After completing education, medical students are expected to provide good medical services, so good mental health must be possessed. But in reality psychological problems occur since the time of medical education. This condition resulted in their unhappiness. Spirituality is believed to play a role in increasing happiness, so increasing spirituality will increase happiness. There has been no research on the relationship between spirituality and happiness in medical students, especially in Indonesia. The purpose of this study was to see the relationship of spirituality for individual medical students that has an impact on happiness. The study adopted an analytical observational type with a cross sectional design. The study subjects were randomly selected by sampling a population of 100 medical students at Universitas Sebelas Maret class of 2020-2023. Primary data were taken using spirituality instruments based on DSES to determine the level of spirituality and happiness instruments based on SHS and SWLS to determine the level of happiness. To analyze ordinal relationships, a spearman correlation test is used. The results showed that medical students at Universitas Sebelas Maret had a high level of spirituality, while the level of happiness was in the medium category. The relationship between spirituality and happiness showed significance with a correlation value of r = 0.179; p = 0.037 (p < 0.005) indicates that there is a weak relationship between spirituality and happiness. Many factors affect happiness, the higher the spirituality of medical students, the higher the level of happiness. Keywords: spirituality; happiness; medical students

This article explored the transition from paradiplomacy to protodiplomacy in Catalonia and Kurdistan, two regions at the forefront of this shift. Protodiplomacy involves the direct participation of subnational entities in diplomatic activities akin to those of recognized nation-states, challenging traditional diplomatic hierarchies and altering the global diplomatic landscape. Catalonia has greater autonomy in matters such as governance and economy, while Kurdistan has more limited autonomy in matters such as security and governance. As such, this research showed that paradiplomacy could serve as a means to increase regional engagement in international politics. This research provided an in-depth analysis of how the South Sulawesi Provincial Government's paradiplomacy initiative impacts the export of agricultural products to Egypt. Through a comparative analysis of Catalonia and Kurdistan, this study elucidated the motivations, consequences, and challenges associated with this transition. It emphasized the significance of effective paradiplomacy practices between central and local governments. Catalonia and Iraqi Kurdistan exemplified modern paradiplomacy, showcasing their capabilities on an international stage. The research identified high Iraqi Kurdish nationalism as a key driver of the shift towards protodiplomacy in Kurdistan. It also highlighted the internal structural factors within Iraq that propelled Iraqi Kurdistan's diplomatic efforts, culminating in a referendum that marked a peak in separatist interest. This research underscored the dynamic nature of protodiplomacy, highlighting the motivations behind subnational diplomatic endeavors and the transformative implications for central-local government relations.

Non-tunneling hemodialysis catheter is one of the most convenient vascular accesses for hemodialysis in End Stage Kidney Disease (ESRD) patients. However, these catheters have the highest morbidity among all available accesses. Current guidelines recommend that non-tunneled hemodialysis catheters be placed for no more than 2 weeks to prevent bacterial contamination. This study was conducted in Dr. Hasan Sadikin General Hospital, Bandung, Indonesia, throughout January-December 2021. A correlation test with a prospective observational analysis design was applied to find the link between the duration of non-tunneled hemodialysis catheter placement and the incidence of positive bacterial culture on the catheter. Pearson correlation test was used to see the strength of the correlation, with a significance limit of 0.05. This study involved 28 subjects. The most common location for catheter placement was in the jugular vein, and laboratory examinations showed no correlation between leukocyte values and positive bacterial culture results. Hypertension and diabetes mellitus were not significant risk factors (p-value 0.887). At ≤14 days of catheter placement, only 1 (6.7%) of the subjects presented a positive culture result. Most of the positive bacterial culture results were found at a duration of 15-30 days of placement, (n=8; 53.3%). The results of the Pearson test showed a p-value of 0.036 and an r-value of 0.399, indicating a significant result with a strong correlation between the two variables. The duration of placement of hemodialysis catheters has a positive correlation with the incidence of positive bacterial cultures, which can increase the risk of systemic infection associated with hemodialysis catheters.

This article delves into the crucial aspects of the Constitutional Court of the Republic of Indonesia's decision, focusing on the emergency state of administrative law concerning open legal policy decisions referred back to legislators, particularly regarding the tenure of village heads. The study employs a conceptual and legal approach, centering on the Constitutional Court Decision No.15/PUU-XI/2023 concerning the village head's position. This represents an open legal policy for law framers, paving the way for the political prevention of Pilkades (village head elections) money politics. Law No. 6 of 2014, which is under consideration for revision, lacks explicit measures against money politics. The methodology adopted is normative legal research that integrates legal theory with legislation. The findings indicate that open legal policy rulings necessitate immediate action by law framers, signaling administrative law urgency. The rationale is that law framers must react to that decision, and revising the law does not necessarily require inclusion in the National Legislation Program (Prolegnas). Decision on open legal policies must be administratively executed by law framers, including the issuance of Government Regulation in Lieu of Law (Perpu), which subsequently require legislative approval to become law. In essence, the decision of the Constitutional Court carries a moral and ethical coercive force, achieved by transforming ius constitutum into ius constituendum.

Abstract An arbitration Agreement between the parties is an important source of law in the arbitration proceeding, especially in International Commercial Arbitration. Arbitration Agreements, which could be made before and after the dispute, provide jurisdiction to the arbitral tribunal to settle the dispute. Traditionally, the arbitration agreement provides that only the parties in the agreement could be bound by the arbitration proceeding. However, in commercial arbitration, there is a circumstance in which a third party could be bound to arbitration proceedings. Indonesia has an arbitration law based on Law No. 30 Year 1999 concerning Arbitration and Alternative Dispute Resolution. This law stipulates how arbitration proceedings could proceed in Indonesia, including third-party issues in arbitration proceedings, as stipulated in Article 30. However, it depends on an arbitrator to settle since the Law itself does not explain further. The definition also does not govern in BANI Rules and Procedure as BANI procedural law. One opinion based on the writer’s research shows that commercial arbitration in Indonesia could also consider Indonesian Civil Procedural Law, as well as the regulation toward third parties’ involvement. Some of the mechanism of third parties’ involvement that has been regulated in Indonesian Civil Procedural Law is Vrijwaring, Tussenkomst, and Voeging. Abstrak Perjanjian Arbitrase di antara para pihak merupakan sumber hukum utama dalam proses arbitrase, khususnya dalam Arbitrase Komersial Internasional. Perjanjian Arbitrase dapat dibuat sebelum dan setelah sengketa, dan merupakan dasar kewenangan dari lembaga arbitrase untuk menyelesaikan sengketa. Secara konsep, perjanjian arbitrase hanya mengikat para pihak yang terikat dalam perjanjian arbitrase. Namun demikian, terdapat kondisi bilamana pihak ketiga dapat terikat dalam proses arbitrase. Indonesia mengatur arbitrase dalam UU No. 30 Tahun 1999 tentang Arbitrase dan Alternatif Penyelesaian Sengketa. Undang-undang ini mengatur bagaimana proses arbitrase di Indonesia, termasuk para pihak dalam proses arbitrase sebagaimana diatur dalam Pasal 30. Hal ini sangat tergantung pada arbiter untuk memutuskannya karena undang-undang tidak memberikan penjelasan lebih lanjut. Penjelasan selanjutnya juga tidak diatur dalam Hukum Acara BANI. Berdasarkan hasil penelitian yang dilakukan, dalam arbitrase komersial di Indonesia, para pihak perlu mempertimbangkan Hukum Acara Perdata yang berlaku di Indonesia, khususnya mengenai pengaturan bagaimana pihak ketiga bisa terikat dalam proses arbitrase. Mekanisme keterlibatan pihak ketiga yang diatur dalam Hukum Acara Perdata Indonesia yaitu Vrijwaring, Tussenkomst, and Voeging.

Islam actually exists as rahmatan lil 'alamin. Understanding of Islam has a balance of reasoning and realistic thinking, and refers to various sources that are comprehensive and consistent. Education is a means of human regeneration to deal with the development of an intellectual civilization that continues to be dynamic by promoting improvements for the good of human life itself. This article uses a descriptive qualitative approach with a literature study data collection technique related to religious moderation in the realm of education. The data is analyzed inductively after first being categorized according to the need for data synchronization. The results of the study prove that mainstreaming religious moderation in Islamic educational institutions in Indonesia is an urgency for a religious and state foundation in this republic. The Republic of Indonesia has a rich culture and various differences that must be preserved in a unified nation based on Pancasila and the 1945 Constitution which was declared by the founding fathers of this nation.

Plastic waste is a growing environmental concern worldwide, and the development of sustainable solutions to manage plastic waste has become a critical priority. One promising solution is the conversion of plastic waste into useful products, such as bricks. This study investigates the potential use of waste polypropylene (PP) bumper, a common automotive plastic waste, to produce eco-friendly bricks. The waste PP bumper was collected from a local industry and mixed with sand in ratios ranging from 100 % PP to 40% PP. The produced bricks were subjected to compression, flexural, and water absorption tests. Results showed that the addition of sand to the PP waste bumper improved the mechanical and water absorption properties of the bricks. In particular, the plastic bricks with minimal inclusion of 5 % bitumen exhibited the highest compressive strength of 8.532 MPa and flexural strength of 1.287 MPa while maintaining low water absorption of 0.04 %. The results of this study suggest that waste PP bumper can be used as a viable raw material for eco-friendly brick production, and the optimal ratio of PP and sand can be determined based on the desired properties of the bricks. The future application of these eco-friendly bricks can be in construction projects in which able to replace traditional clay bricks and contribute to the reduction of plastic waste in landfills.

This study addresses the challenge of preferential weld corrosion in ASTM A333 carbon steel piping, investigating the intricate interplay of various factors. The welding process induces microstructural alterations, making affected areas more prone to corrosion, resulting in Preferential Weld Corrosion (PWC). While the addition of 1 % nickel filler shifts the galvanic potential of Weld Metal (WM), its impact on PWC is marginal due to the high rates of its intrinsic corrosion. Notably, nickel filler addition accelerates corrosion in the heat-affected zone (HAZ). In carbon dioxide (CO2) environments, the presence of acetic acid (HAc) intensifies corrosion; yet, the application of morpholine as pH neutralizer effectively counters its effects. Imidazoline based corrosion inhibitor prove successful in PWC mitigation, particularly at elevated pH levels. Furthermore, Post Weld Heat Treatment (PWHT) significantly reduces hardness, aligning with a decrease in corrosion. Of paramount importance, this study not only examining the effects of individual factors, including microstructure, pH adjustment, corrosion inhibitors, and PWHT, but also scrutinizing their combined impacts. The integration of PWHT with pH adjustment and inhibitor injection yields corrosion rates below 0.1 mm/y, ensuring a remarkable 30-year service life even under challenging conditions. This study underscores the necessity of a comprehensive strategy, combining these factors, to effectively manage preferential weld corrosion in carbon steel weldments.

Age estimation in adults is a complicated task because of various external factors occur concurrently with increasing age. The geometric morphometric method (GMM) is an approach that focuses on shape analysis and is widely recognized for its high reliability and reproducibility. The aim of this study was to explore the variation of cervical vertebrae among different age groups of the Malaysian population by GMM. Lateral skull radiographs of 432 subjects comprising four adult age groups; young adult age group (20–30 years old), early middle age group (31–40 years old), late middle age group (41–50 years old) and, elder adult age group (51–60 years old) were selected. Fifty-three 2-dimensional (2D) landmarks were applied to the digitalized radiographs by TPSDig2 (Version 2.31) software. Geometric morphometric analysis was performed by MorphoJ software. Results showed that the first three principal components (PC) contributed to 47.71 % of the cervical vertebrae variation and were shown in both lollipop and wireframe graphs. Procrustes ANOVA indicated that the shape was significantly different among different age groups. Canonical variate analysis revealed significant differences of both mahalanobis and procrustes distances among age groups with substantial individual overlap within groups. Discriminant function analysis (DFA) showed a correct classification rate for 61.5 % of cases respective to age groups. In conclusion, this study found significant differences in the shape of cervical vertebrae among different age groups of the Malaysian population using the GMM.

The hydrographic survey reduction using ellipsoid has been available since the advent of the global navigation satellite system (GNSS), with a potential to streamline operation and enhance bathymetric output. Spatially continuous separation surfaces connecting a chart datum (CD) to a geodetic ellipsoid is required for this technique. Universiti Teknologi Malaysia (UTM) has invented a new quasi-seamless separation model for Malaysian waters, known as the Malaysian Vertical Separation (MyVSEP) model, through semi-empirical models to capture the spatial variability of a tidal datum between coastal and offshore areas. A continuous vertical datum is established to develop MyVSEP models by combining the coastal and offshore datasets. The coastal datasets referred to the vertical reference point computed from coastal tide gauges, while the offshore datasets referred to the vertical reference surfaces derived from satellite altimetry. Mean sea level (MSL) or mean sea surface (MSS), mean dynamic topography (MDT), lowest astronomical tide (LAT), and highest astronomical tide (HAT) are the vertical datums involved in developing the continuous MyVSEP model. However, the integration of the vertical datum has only been conducted over the Peninsular Malaysia region. For Sabah and Sarawak, datum integration cannot be implemented due to the limitation of coastal datasets. The assessment of the integrated vertical datum with coastal tide gauges is discussed in this study. The finding shows that the root mean square error (RMSE) agreement between the integrated Universiti Teknologi Malaysia 2020 (iUTM20) model and coastal tide gauges yields below 2.0 cm. The iUTM20 lowest astronomical tide and highest astronomical tide models also show significant improvement compared to the altimetric-derived tidal models, which recorded the root mean square error agreement with coastal tide gauges of 1.8 cm and 2.0 cm, respectively. The development of a continuous vertical separation model for the Ellipsoidally Referenced Surveying technique indirectly optimizes marine geospatial information resources, especially for the National Hydrographic Centre in Malaysia.

BackgroundAccording to the World Bank, Malaysia reported an estimated 97 tuberculosis cases per 100,000 people in 2021. Chest x-ray (CXR) remains the best conventional method for the early detection of pulmonary tuberculosis (PTB) infection. The intervention of artificial intelligence (AI) in PTB diagnosis could efficiently aid human interpreters and reduce health professionals’ work burden. To date, no AI studies have been evaluated in Malaysia. ObjectiveThis study aims to evaluate the performance of Putralytica and Qure.ai software for CXR screening and PTB diagnosis among the Malaysian population. MethodsWe will conduct a retrospective case-control study at the Respiratory Medicine Institute, National Cancer Institute, and Sungai Buloh Health Clinic. A total of 1500 CXR images of patients who completed treatments or check-ups will be selected and categorized into three groups: (1) abnormal PTB cases, (2) abnormal non-PTB cases, and (3) normal cases. These CXR images, along with their clinical findings, will be the reference standard in this study. All patient data, including sociodemographic characteristics and clinical history, will be collected prior to screening via Putralytica and Qure.ai software and readers’ interpretation, which are the index tests for this study. Interpretation from all 3 index tests will be compared with the reference standard, and significant statistical analysis will be computed. ResultsData collection is expected to commence in August 2023. It is anticipated that 1 year will be needed to conduct the study. ConclusionsThis study will measure the accuracy of Putralytica and Qure.ai software and whether their findings will concur with readers’ interpretation and the reference standard, thus providing evidence toward the effectiveness of implementing AI in the medical setting.

Learning PAI online raises various problems that have an impact on students' mental and spiritual. The object of this research study is junior high school students because they have an unstable nature and patterns of thinking. The purpose of this study was to determine the problems of the impact of the weak mental and spiritual students. So that efforts can be made to develop students with the application of PAI subjects. This study uses descriptive qualitative methods in the analysis that has been carried out to solve post-pandemic problems. The results of this study indicate that the online learning provided by the teacher is expected to be effective and ideal. However, not all subjects can apply this because of the challenges and obstacles, especially in PAI lessons. Because there are 6 basic topics of discussion including Akidah-Akhlaq, Qur'an-Hadith, Fiqh, and History of Islamic Culture (SKI). Online learning on PAI subjects turned out to have an effect on students' mental and spiritual. Most students who are mentally and spiritually weak will have various disorders of morality. For this reason, there is a need for mental spiritual development from PAI learning such as advice from the al-Qur’an and Hadith.

The production in industry, are involving distribution to transport the goods. Recently, distribution activities are using unmanned vehicle, that is Automated Guided Vehicle (AGV). In real condition, AGV are facing environment with complexity of high uncertainity and unlinearity. Because of this, robust control method could be considered to be used to improve the control performance.

This phenomenon could damage the motor. This research aim to reduce chattering and improve the control performance, with modifying signum function to saturation function. This research are using ROS, V-Rep and microcontroller. Microcontroller for processing algorithm and another function. Moreover, saturation function had succcessfully reducing rise time about 30%, overshoot 16% and RMSE 0.21%.

Abstract Background Cardiac tamponade occurs when fluid or blood, fills the pericardial space, and causes hemodynamic compromise due to compression of the heart. It is a potentially life-threatening condition, that requires rapid recognition and immediate treatment. Formerly, blind or surgical techniques were used, and it is associated with complications. Medical technology development has enabled us to perform the procedure safely, with the assistance of ultrasound devices. This article will highlight the novel use of an in-plane subcostal technique, as a safe option for pericardiocentesis in cardiac tamponade. Case presentation A 50-year-old man presented to the emergency department (ED) with shortness of breath and shock. He was intubated for respiratory distress. His bedside echocardiography showed cardiac tamponade. Ultrasound-guided pericardiocentesis was carried out using an in-plane technique, at the subcostal region, with a high-frequency linear ultrasound transducer. This particular method provided full visualization of needle trajectory throughout the procedure. It was successfully completed with no complications and patient’s hemodynamic status improved post-procedure. He was successfully discharged on day 13. Conclusions The in-plane subcostal pericardiocentesis is a safe, and simple approach that can be performed in the ED for patients with cardiac tamponade. We recommend this new in-plane method, with high-frequency linear transducer at the subcostal area as an alternative when cardiac window for other approaches cannot be visualized.

Mild steel is a type of carbon steel with quite a low carbon content, or particularly known as plain-carbon steel. It is often used as a construction material because of its relatively low price. However, unlike stainless steel, it has low corrosion resistance, therefore some form of a protective film should be applied to prevent it from rusting in the corrosive environment. The inhibiting action of the synthesised dithiocarbamates (DTC), namely, Co(II) N-butylmethyldithiocarbamate, Co[BuMedtc]2 and Co(II) N-ethylbenzyldithiocarbamate, Co[EtBenzdtc]2 towards the corrosion behaviour of mild steel in acidic solution was studied. The proposed structures of complexes were characterised by using Fourier transform infrared (FTIR), ultraviolet-visible (UV-Vis), gravimetric analysis, molar conductivity, and melting point measurement. The analysis data deduced that the DTC ligands have successfully coordinated to Co(II) ion in a bidentate manner. The corrosion inhibition study showed that Co[BuMedtc]2 was a better corrosion inhibitor compared to Co[EtBenzdtc]2 because this is most likely due to the presence of a less bulky alkyl substituent (-CH3) in Cu[BuMedtc]2 and hence, showing great corrosion inhibition performance. Besides, the shorter the alkyl chain length in Cu[BuMedtc]2, the higher the solubility of the complex in the acid medium. The complexes showed better effectiveness in hydrochloric acid (HCl) rather than sulphuric acid (H2SO4) solution. The corrosion happened more actively in HCl than H2SO4 due to the chloride ions shown more destructive effect than sulfate ion on the carburised low carbon steel samples. In addition, when the concentration of inhibitor increases, the corrosion rate will be decreased.

An early detection of disease can save the plant. One of the ways is by using eye-observation, which is time-consuming. Having a machine learning technology that can automate early detection would benefit modern and conventional farming. This study emphasizes the review of Hyperspectral Image (HSI) reconstruction using the Hierarchical Synthesis Convolutional Neural Networks (HSCNN) based method in early plant disease detection. Capturing hundreds of spectral bands during image acquisition enables the HSI capturing devices to provide more detailed information. Detection of disease with Red Green Blue (RGB) images needs to be done when it shows a notable spot or sign. However, the disease can be spotted with the correct range of spectral bands on HSI before a notable spot or sign is shown. The usage of HSI image is significantly important as it is rich in information and properties needed for image detection. Although HSI device is significantly important in early plant disease detection, the devices are expensive and require specialized hardware and expertise. Thus, reconstructing the Reg Green Blue (RGB) image to HSI is required. This research implemented two types of HSCNN-based methods, Densed network (HSCNN-D) and Rectified Linear Unit network (HSCNN-R), for HSI reconstructions. The results show that HSCNN-D outperformed the HSCNN-R with less Mean Relative Absolute Error (MRAE) of 2.15%.

Upwelling is a vital ocean behaviour, especially for the Fisheries Industry, where upwelling will help to detect fish ground at a particular ocean area. However, the study of upwelling is minimal and not well understood due to some reasons and constraints, such as limited observation. Upwelling lacks a comprehensive in-situ observation system where it relies on limited information collected from the ground-truthing execution such as ships, buoys, and current meter. This study aims to analyse the upwelling pattern in the southern region of the South China Sea by using a multi-mission satellite altimeter. In order to derive the physical oceanography that involves upwelling, such as sea surface height (SSH), Mean Dynamic Topography (MDT), and the Sea Level Anomaly (SLA), the Radar Altimeter Database System is used. Five Satellite Altimeter mission is used in this study, which is JASON-2, JASON-3, CYROSAT2, SARAL, SENTINAL3A from 2013 to 2017. Validation is made using a statistical method showing a good correlation between Altimetry data and Tidal Data at tide gauge, which is 0.84 to 0.97, respectively. Also, monthly altimetry derived Geostrophic Current was assessed by analysing the current pattern where it shows a similarity with a previous study where the current velocity is 0.5ms-1 to 2ms-1. From the result, eddies can be seen in the seasonal and monthly Absolute Geostrophic Ocean Current (AGOC) map, indicating the present presence of upwelling. In conclusion, this study will benefit other researchers in terms of both upwelling and eddy studies.

The purpose of this study is to describe the application of the reward and punishment method in increasing English vocabulary and to explore information about the advantages and disadvantages of the reward and punishment method. The research method in this study is a descriptive method. Data collection techniques were carried out by observation, interviews, and documentation. The results of this study found that mastery of English vocabulary increased. In addition, the level of confidence and student satisfaction in the learning process is getting better. The practice of giving rewards and punishments is adjusted to the needs of students. Rewards are in the form of handicraft gifts, praise, and grades. While punishment is in the form of repetition of material and not getting a prize. The advantage of this method is that it fosters a sense of competitiveness and motivates maximum learning. While the drawbacks of this method are in the form of costs that must be prepared for gifts and focus on only active students, on the contrary it becomes a burden for students who are lazy and have weak mentality.

Microbial community diversity of healthy and unhealthy shrimp (Penaeus vannamei) with early mortality syndrome (EMS), collected from shrimp farms in Kedah and Penang, Malaysia, were examined using a cultivation method and 16S rRNA gene analysis. This study aimed to describe and identify the major abundance of shrimp’s microbial communities and its relationship with shrimp health status (healthy or unhealthy with EMS). In 16S rRNA gene analysis of metagenomic and culturable bacterial numbers, these were found to differ between healthy and unhealthy cases, whereby the bacterial community diversity might have potentially contributed to the health status. The results revealed significant differences by healthy status and by sampling time. Based on the results, the bacterial communities of healthy shrimp were composed of members of the genera Pseudomonas (32% of the total reads), Photobacterium (21% of the total reads), Acinetobacter (15% of the total reads) and Vibrio (10% of the total reads). Meanwhile, the members of the genera Vibrio (40% of the total reads), Photobacterium (25% of the total reads), Pseudomonas (10% of the total reads) and Paracoccus (7% of the total reads), were greatly predominant in unhealthy shrimp with EMS, with highly dynamic bacterial communities.

Abstract The development of urban accumulations in recent decades has led to the transformation of urban heat islands (UHI) into regional heat islands (RHI). The contributions of the biophysical, climate, and socioeconomic factors to RHI in urban agglomeration remain poorly understood. Here Yangtze River Delta urban agglomeration (YRDUA) in eastern China has been selected as a case area to explore the influences trends, of the influencing factors to RHI by using MODIS data from 2003 to 2017. Results showed that, in summer, the area fraction of daytime RHI in YRDUA has increased from 21.74 to 31.03% in 2003 and 2017, respectively. As compared to 2003, the annual nighttime RHI area in 2017 has increased from 7510 to 20,097 km2. The dominant factors of surface RHI intensity (SRHII) showed seasonal variation. Enhanced vegetation index (EVI) (interpretation of 33.27%) was the dominant factor of daytime SRHII in spring. The most important factor was normalized difference build-up density (NDBI) (37.28% and 26.83%, respectively) in summer and autumn. In winter, precipitation (26.16%) was the most influential. At night, Modified Normalized Difference Water Index (MNDWI) had a dominant effect on SRHII in spring (54.12%), autumn (52.62%), and winter (24.19%). The dominant factor of nighttime SRHII in summer was EVI (42%). Moreover, water bodies harm RHI during the day while having a positive effect at night. These findings can provide a theoretical basis for regional environment improvement and regional sustainable development.

Honey has a long history of therapeutic properties for multiple diseases, including inflammation and oxidative stress. This review aimed to provide a better understanding and renewed interest in the potential role of honey in obesity control, obesity-related diseases treatment and weight management, with specific reference to its components and the effect of honey overall. There is compelling evidence that honey possesses the desired properties for this purpose, as seen in the in vitro , in silico, in vivo and clinical analyses discussed in this review. This review also highlights the components potentially responsible for the health benefits of honey. Honey and its components reduce blood sugar levels, improve insulin sensitivity and lipid metabolism by reducing triglycerides, and reduce total cholesterol and LDL levels while increasing HDL levels that prevent excessive weight gain and reduce the risk of obesity and its complications. Further controlled studies are necessary to validate the role of honey in the management of obesity, both as a preventive and as a therapeutic agent.

Ticks transmit a number of bacterial, protozoal and viral pathogens that cause many diseases like ehrlichiosis, hemorrhagic fever, theileriosis, babesiosis and anaplasmosis in livestock. This study was designed for molecular characterization of BM86 gene of Rhipcephalus (Boophilus) microplus tick. In this study, the BM86 gene was amplified, using primers fl anked by restriction enzyme sites. The molecular detection of R. microplus was studied in three districts belonging to diff erent ecological zones in the province of the Punjab, Pakistan. Tick samples were collected and initially screened through microscopy and further analyzed by PCR and sequencing, the phylogenetic tree generated by using the MEGA 7 through Neighbor Joining method using best model through the phylogenetic analysis of R. microplus. Pairwise comparisons of nucleotide sequences showed nucleotide diff erences ranging between 0.007 and 0.01%. Haplotype and nucleotide diversity in Bm86 gene was found among diff erent districts. Six single nucleotide polymorphism were seen sequences of BM 86 from indigenous tick population collected from the Punjab province. More interestingly out of these 6 polymorphism we got 2 from district Okara, 3 from district Sahiwal, and 1 in Mandi Bahauddin. Conserved regions were observed among the local strains for BM86 gene. A common convergence in similar clade was with the local Pakistan R. microplus. Local mean diversity was 0.005 and overall mean diversity was 0.038. Field strain has been isolated as candidate specie for local tick vaccine, which in turn will increase the efficacy of future tick vaccine including reduction of economic burden on the farmer.

Actinomycete is one of the beneficial bacteria groups inhabiting rhizosphere soil. They can promote plant growth through various mechanisms. In the previous study we have isolated rhizosphere actinomycetes from maize rhizosphere with direct plant growth promotion characters. The aims of the present study were to analyze the ability of maize rhizosphere actinomycetes to solubilize phosphate, determine alkaline phosphatase activity, and study their genetic diversity based on phoD gene. Thirteen rhizosphere actinomycete isolates were able to solubilize phosphate at concertation range 55.84±2.27 mg/L to 144.48±5.71 mg/L. The activity of extracellular alkaline phosphatase was exhibited by all maize rhizosphere actinomycetes isolates in various level ranging from 0.08 mU/mL to 0.51 mU/mL. The phoD gene, one of the three homologous genes which encode alkaline phosphatases, was successfully detected in all isolates and identified as alkaline phosphatase D of Streptomyces spp. The partial phoD sequences of the isolates were located within metallophosphatase domain of alkaline phosphatase D. Alignment analysis showed that the deduced amino acid sequences of PhoD were mostly conserved in the isolates and Streptomyces spp. Essential residues involved in the active core arrangement of PhoD which binds metal ion cofactors were conserved. Constructed phylogenetic tree showed that the isolates were divided into two groups within PhoD cluster. PhoD of the isolates and Streptomyces spp. had closer relationship to purple acid phosphatase compared to other homologous PhoA and PhoX which form separate cluster. Generated three-dimensional structure model of partial PhoD had high similarity to alkaline phosphatase D of Bacillus subtilis (2YEQ) and showed overlapping structure based on super-positioning analysis.

To enable conservation of degraded land requires Map of Conservation Activity Plan (CAP). The map is established based on a model developed by the then Ministry of Environment and Forestry. One step to analyze the CAP is land unit elimination (LUE) having area of < 1 cm2. This study aimed to determine the effect of LUE on the CAP at Air Bengkulu Watershed. Maps used for input to CAP are EHL (Erosion Hazard Level), Soil Depth, Slope, Population Pressure, and the Recommended Landuse, whereas to calculate EHL requires R, K, LS, C, and P Factors. CAP Map as a result without involving LUE is compared to the CAP Map with involving LUE. The research result showed that the LUE influences on the change of the recommended of the CAP up to 77.6% of the total area of the study, either in engineering recommended or in vegetatively recommended conservation, while the rest (22.4%) were unchanged.

The study investigated the potential of probiotic isolate Bacillus subtilis AsCh-A4 (Accession No. MF543124) fermented feed to improve growth profile of Labeo rohita fingerlings. Morphometric measurements and nutritional indices of control and experimental groups were compared fortnightly in 90 days experiment. The formulated fish feed was fermented by Bacillus subtilis AsCh-A4 up to seven days and administered at 3% (b/w) with live (G1) and dead (G2) bacterium. G1 group showed significant higher values of DG (Daily gain) and RGR% (percent relative growth rate) in wet body weight than control and G2 while Specific Growth Rate (0.08 – 0.11%) in G1 within phase IV – VI followed by G2 (0.07%) at phase IV over control group. In all groups, the computed condition factor was 1.13, 0.91, 1.09 indicating isometric fish growth. Significantly increased body contents i.e., total protein (phase IV – VI), total carbohydrate (phase V) in G1 and DNA (phase IV) in G1 as well as G2 (phase II – III). Moreover, no significant change was assessed in total lipids, cholesterol, RNA contents, Alkaline phosphatase, Alanine aminotransferase, protease and somatic indices in all groups. Aspartate aminotransferase and acid phosphatase were significantly decreased in G1 (phase II – III) and G2 (phase III) while amylase increased in G1 (phase II). These results clearly demonstrated the growth promoting effect of the probiotics for rohu fish.

Apart from the major drawback of black staining once lesion is arrested, few studies have indicated that dental personnel’s perception and attitude towards silver diamine fluoride (SDF) influences its usage. This report aims to provide a systematic review presenting dental personnel’s knowledge, attitudes, and perceptions, (KAPs) regarding SDF. A search of multiple electronic literature databases and a manual search were performed. The review was reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 statement. A comprehensive search yielded 719 publications and 14 cross-sectional studies matching the inclusion criteria. Awareness of SDF among respondents ranged from 29.6% to 87.8%, whereas awareness of its use in dentistry ranged from 14.4% to 94.5%. Regarding attitude towards SDF, the mean score ranged from 3.39 to 14.35. An increase in knowledge of and attitude towards SDF is significantly associated with the usage of SDF and may increase the usage of SDF. This review provides vital information on dental personnel’s KAPs regarding SDF. It is anticipated that the adaptation of SDF usage will be more widespread in the future, especially among children. Findings from the review may assist intervention programs to change misperceptions and to enhance awareness regarding SDF among dental personnel.

Contemporary Universiti Teknologi Malaysia 2020 Mean Sea Surface (UTM20 MSS) and Mean Dynamic Topography (UTM20 MDT) models around Malaysian seas are introduced in this study. These regional models are computed via scrutinizing along-track sea surface height (SSH) points and specific interpolation methods. A 1.5-min resolution of UTM20 MSS is established by integrating 27 years of along-track multi-mission satellite altimetry covering 1993–2019 and considering the 19-year moving average technique. The Exact Repeat Mission (ERM) collinear analysis, reduction of sea level variability of geodetic mission (GM) data, crossover adjustment, and data gridding are presented as part of the MSS computation. The UTM20 MDT is derived using a pointwise approach from the differences between UTM20 MSS and the local gravimetric geoid. UTM20 MSS and MDT reliability are validated with the latest Technical University of Denmark (DTU) and Collecte Localisation Services (CLS) models along with coastal tide gauges. The findings presented that the UTM20, CLS15, and DTU18 MSS models exhibit good agreement. Besides, UTM20 MDT is also in good agreement with CLS18 and DTU15 MDT models with an accuracy of 5.1 and 5.5 cm, respectively. The results also indicate that UTM20 MDT statistically achieves better accuracy than global models compared to tide gauges. Meanwhile, the UTM20 MSS accuracy is within 7.5 cm. These outcomes prove that UTM20 MSS and MDT models yield significant improvement compared to the previous regional models developed by UTM, denoted as MSS1 and MSS2 in this study.

BackgroundIn Malaysia, the Sugar-Sweetened Beverages (SSBs) tax was announced during the parliament's 2019 Budget Speech. The tax was slated to be enforced by April 2019 but was later postponed to July 2019. The announcement has since generated significant media coverage and public feedback. ObjectiveThis study presents a qualitative and quantitative cross-sectional study using netnography to examine how Malaysian online news articles responded to the SSBs tax after the announcement and postimplementation. MethodsOnline news articles published on popular online news platforms from November 2018 to August 2019 were downloaded using NCapture and imported into NVivo for analysis using the inductive approach and thematic content analysis following the initial SSBs implementation announcement. ResultsA total of 62 news articles were analyzed. Most of the articles positively portrayed the SSBs tax (46.8%) and highlighted its health impacts (76%). There were 7 key framing arguments identified in the articles. The positive arguments revolved around incentivizing manufacturers to introduce healthier products voluntarily, positive health consequences, the tax’s impact on government revenue, and the use of the generated revenue toward beneficial social programs. The opposing arguments included increased operating costs to the manufacturer, the increased retail price of drinks, and how the SSBs tax is not a robust solution to obesity. The top priority sector considered in introducing the tax was the health perspective, followed by economic purposes and creating policies such as regulating the food and drinks industry. ConclusionsThe majority of online news articles positively reported the implementation of the SSBs tax in Malaysia. This suggests media played a role in garnering support for the health policy. As such, relevant bodies can use negative findings to anticipate and reframe counteracting arguments opposing the SSBs tax.

Different modification methods and software programs were developed to obtain accurate local geoid models in the past two decades. The quantitative effect of the main factors on the accuracy of local geoid modeling is still ambiguous and has not been clearly diagnosed yet. This study presents efforts to find the most influential factors on the accuracy of the local geoid model, as well as the amount of each factor's effect quantitatively. The methodology covers extracting the quantitative characteristics of 16 articles regarding local geoid models of different countries. The Statistical Package of Social Sciences (SPSS) software formulated a strong multiple regression model of correlation coefficient r = 0.999 with a high significance coefficient of determination R2 = 0.997 and adjusted R2 = 0.98 for the required effective factors. Then, factor analysis is utilized to extract the dominant factors which include: accuracy of gravity data (40%), the density of gravity data (25%) (total gravity factors is 65%), the Digital Elevation Model (DEM) resolution (16%), the accuracy of GPS/leveling points (10%) and the area of the terrain of the country/state under the study (9%). These results of this study will assist in developing more accurate local geoid models. Keywords: Accuracy of local geoid model, Multiple regression model, Influence factors

Thickness checking is one of the quality control procedures in the brake pad industry. This research aims to address the issue of the time effectiveness of the thickness checking by turning the technique into an automatic process, from specimen preparation to data recordings; the technical aspects, the geometric design, and the structure analysis are critical elements of the industrial machinery. However, economic analysis is considered when it becomes an investment by a company with long-term use expectations. Thus, this research provides structural analysis, time checking estimation, and simple investment feasibility studies on break-even points and a simple payback period to ensure that the new design can improve testing performance. Monte Carlo simulation offers the calculation of investment feasibility with the three possibilities of pessimistic, optimistic, and realistic results in achieving a break-even point (BEP) and a simple payback period.

During the last few years, there has been an increase in public awareness of antimicrobial fabrics, as well as an increase in commercial opportunities for their use in pharmaceutical and medical settings. The present study reports on the optimized fabrication of protonated polyaniline (PANI)-integrated polyester (PES) fabric. Para-toluene sulfonic acid (pTSA) was used to protonate the PANI fabric and thus grant it antibacterial performance. The results of a 1,1-diphenyl-2-picrylhydrazyl (DPPH) scavenging assay showed high antioxidant activity of protonated PANI fabric at a scavenging efficiency of 84.83%. Moreover, the findings revealed remarkably sensitive antibacterial performance of PANI-integrated fabric against the following Gram-positive bacteria: methicillin-resistant Staphylococcus aureus (MRSA), S. epidermidis, and S. aureus; and also against the following Gram-negative bacteria: P. aeruginosa, E. coli, and S. typhi. Attenuated total reflectance–Fourier transform infrared (ATR–FTIR) spectroscopy and energy dispersive X–ray fluorescence (EDXRF) were used to determine the changes in the structural and elemental compositions of PANI fabric upon treatment with bacterial strains. Electrochemical impedance spectroscopy (EIS) revealed that the electrical conductivity value of protonated PANI fabric decreased by one (1) order of magnitude against P. aeruginosa and S. aureus, from 3.35 ± 7.81 × 10−3 S cm−1 to 6.11 ± 7.81 × 10−4 S cm−1 and 4.63 ± 7.81 × 10−4 S cm−1, respectively. Scanning electron microscopy (SEM) analysis showed the disruption of bacterial membranes and their structures when exposed to protonated PANI fabric; meanwhile, thermogravimetric analysis (TGA) demonstrated that the fabric retained its thermal stability characteristics. These findings open up potential for the use of antimicrobial fabrics in the pharmaceutical and medical sectors.

The study of geopolymers has become an interesting concern for many scientists, especially in the infrastructure sector, due to having inherently environmentally friendly properties and fewer energy requirements in production processes. Geopolymer attracts many scientists to develop practical synthesis methods, useful in industrial-scale applications as supplementary material for concrete. This study investigates the geopolymerization of fly ash and geothermal silica-based dry activator. The dry activator was synthesized between NaOH and silica geothermal sludge through the calcination process. Then, the geopolymer mortar was produced by mixing the fly ash and dry activator with a 4:1 (wt./wt.) ratio. After mixing homogeneously and forming a paste, the casted paste moved on to the drying process, with temperature variations of 30, 60, and 90 °C and curing times of 1, 3, 5, 7, 14, 21, 28 days. The compressive strength test was carried out at each curing time to determine the geopolymer’s strength evolution and simulate the reaction’s kinetics. In addition, ATR-FTIR spectroscopy was also used to observe aluminosilicate bonds’ formation. The higher the temperature, the higher the compressive strength value, reaching 22.7 MPa at 90 °C. A Third-order model was found to have the highest R2 value of 0.92, with the collision frequency and activation energy values of 1.1171 day−1 and 3.8336 kJ/mol, respectively. The utilization of coal fly ash and silica geothermal sludge as a dry activator is, indeed, an approach to realize the circular economy in electrical power generations.

Development of reason or innovative creative thinking in Islamic education so far has been seen as not having a normative and theological foundation in the Koran so that it is clashed with the development of morals that already have a normative basis in the Koran, namely qolb. This study analyzes the concept of ‘Aql in the Koran as a normative-theological foundation for critical, creative and innovative thinking in Islamic education. The approach in this study is a qualitative type of library research. The data source in this study is the interpretation of the Qur'anic verses about the activities of thinking or berpikir ‘Aql, such as thinking (fikr), pondering (taddabur), understanding (tabashshur), understanding and so forth. The data analysis technique used in this study is interpretive hermeneutics. Qur'anic verses about neuroscience can be traced through key terms that refer to brain activity. The results showed that the interpretation of neuroscience verses can be traced through the concepts of tafakur, tadabur, ta'aqul, and so on. The interpretation of the concept of ‘Aql in the perspective of neuroscience can be a theological normative foundation in the development of critical, creative and innovative thinking in Islamic education. the results of this study will have implications for the paradigm of Islamic education which was originally only oriented to developing dichotomic qolb-based morals into the development of the critical thinking potential of students who are more holistic with a more scientific approach.

When a car is parked under the sunlight for a long period of time, solar radiation enters the vehicle through the car glass and becomes trapped inside the car. This causes the cabin interior air temperature to increase and this is especially noticeable in tropical countries with hot and humid climates that are situated near the equator like Brunei Darussalam. Aside from causing thermal discomfort to the passengers inside the car, degradation of the surfaces of the car interior may also be accelerated. This paper aims to demonstrate the severity of the heat by recording a number of temperature measurements in a certain period of time for two different types of cars, under three different conditions for each car and comparing them to the ambient temperature. It is observed that the interior temperature depends on the design of the car. We experimented temperature measurements for two types of car models, i.e., saloon and SUV models. Saloon car is design such as way that its interior volumes space is smaller than the SUV designed car. The smaller interior volume spaced Saloon car exhibits higher maximum temperature of 68.7°C whereas the larger interior volume spaced SUV car exhibits maximum temperature of 59.4°C under fully exposed to sun with same environmental conditions.

Human beings and the complexity they have will never run out to be studied and discussed. So, one of interesting topics of psychology to discuss is concept of ‘fitrah’. The most essential identity of human beings is ‘fitrah’. This issue is more interesting if it is viewed through two perspectives: modern psychology and Islamic psychology. Both kinds of psychology have denied each other. The basis of modern psychology which is separated from element of divinity, makes the conception of ‘fitrah’ dichotomist-secularistic, this is the opposite of Islamic psychology. According to Islam, human beings consist of bodies and rûḥ. Obviously, the two aspects have a specific purpose. At least, Allah states that the purpose of human creation consists of two things, worshipping Him and becoming His khalîfah on this earth. So, the paradigm of Islamic psychology is absolutely related to the element of divinity. God remains the highest subject and influences the paradigm of Islamic psychology which is being tawḥîdiy. For various natural structures they have and the purpose of their creation, human beings are considered to have goodness potency and could do good things. However, external influences still allow them to do evil doings or bad things. This paper discusses this concept of ‘fitrah’ using Islam as a paradigm. The author tries to explain the concept of man as a creature created by fitrah, its physical and psychological structure, and the purpose of human creation and its implications for the psychology paradigm of Islam.

Silver (Ag) particles have sparked considerable interest in industry and academia, particularly for health and medical applications. Here, we present the “green” and simple synthesis of an Ag particle-based silicone (Si) thin film for medical device applications. Drop-casting and peel-off techniques were used to create an Si thin film containing 10–50% (v/v) of Ag particles. Electro impedance spectroscopy (EIS), X-ray diffraction analysis (XRD), scanning electron microscopy (SEM), energy dispersive X-ray (EDX), and tensile tests were used to demonstrate the electrical conductivity, crystallinity, morphology-elemental, and mechanical properties, respectively. The oriented crystalline structure and excellent electronic migration explained the highest conductivity value (1.40 × 10−5 S cm−1) of the 50% Ag–Si thin film. The findings regarding the evolution of the conductive network were supported by the diameter and distribution of Ag particles in the Si film. However, the larger size of the Ag particles in the Si film resulted in a lower tensile stress of 68.23% and an elongation rate of 68.25% compared to the pristine Si film. The antibacterial activity of the Ag–Si film against methicillin-resistant Staphylococcus aureus (MRSA), Bacillus cereus (B. cereus), Klebsiella pneumoniae (K. pneumoniae), and Pseudomonas aeruginosa (P. aeruginosa) was investigated. These findings support Si–Ag thin films’ ability to avoid infection in any medical device application.

Herein we report the synthesis and characterization of electro-conductive chitosan–gelatin–agar (Cs-Gel-Agar) based PEDOT: PSS hydrogels for tissue engineering. Cs-Gel-Agar porous hydrogels with 0–2.0% (v/v) PEDOT: PSS were fabricated using a thermal reverse casting method where low melting agarose served as the pore template. Sample characterizations were performed by means of scanning electron microscopy (SEM), attenuated total reflectance–Fourier transform infrared spectroscopy (ATR–FTIR), X-ray diffraction analysis (XRD) and electrochemical impedance spectroscopy (EIS). Our results showed enhanced electrical conductivity of the cs-gel-agar hydrogels when mixed with DMSO-doped PEDOT: PSS wherein the optimum mixing ratio was observed at 1% (v/v) with a conductivity value of 3.35 × 10−4 S cm−1. However, increasing the PEDOT: PSS content up to 1.5 % (v/v) resulted in reduced conductivity to 3.28 × 10−4 S cm−1. We conducted in vitro stability tests on the porous hydrogels using phosphate-buffered saline (PBS) solution and investigated the hydrogels’ performances through physical observations and ATR–FTIR characterization. The present study provides promising preliminary data on the potential use of Cs-Gel-Agar-based PEDOT: PSS hydrogel for tissue engineering, and these, hence, warrant further investigation to assess their capability as biocompatible scaffolds.

This article presents the research methodology of hadith in the motivation books in Malaysia. There are ten books have been collected and 149 of hadith that have been research in this study. However, the researchers only studied 123 hadith, while 26 hadith are repeated. Based on the analysis of the status of 123 hadith, the researchers found 75 hadith were rated as maqbul hadith (Sahih and hasan), 42 hadith have had on the chain (sanad), and the remaining 6 hadith undetermined status. This study is a contribution to the writing of Islamic studies to enable the reader to know the status of the hadith set forth in motivational books whether it is accepted or rejected. In addition, this study also provides a set of guidelines for writers of motivational books genre to present hadith into their works. It would be beneficial to authors who have no background in Islamic studies and studies of hadith in producing better quality.
