ICT policy is required to facilitate e-services to the citizens and to guide stakeholders of ICT to minimize the socio-economic barriers in ICT facilities. This study has examined the vision, objectives, strategic themes of the National Information and Communication Policy (NIP) 2018 of Bangladesh to find out whether this policy addresses ‘Digital Divide’ and encouraging digital inclusion of Bangladesh. In last decade, the government of Bangladesh has initiated massive digitization, still the question remains, are the citizens receiving the e-services at doorstep or it is creating digital divide. Bangladesh is an agricultural country and 62% of citizen live in rural areas. Furthermore, for receiving e-services it requires ICT accessibility, engagement, and skill, but most of the citizen do not have those perquisites. That is why, rapid digitization and e-services of the government has created the possibility of digital divide. This study has investigated the e-services accessibility for the citizen as committed in ICT policy 2018. For this study, author followed a qualitative method for primary data collection. Author has examined the NIP 2018 with relevant policy documents and finds the underlying gaps and issues, which have the threats of digital divide. Author has also conducted FGDs and Key Informant Interview (KII) to find out possible policy solution. The author has identified the issues, challenges, and gaps while analyzing the NIP 2018. Despite that, the author has proposed, if the NIP 2018 would implement with priority and dedication, the government of Bangladesh can minimize the threats of digital divide and bring the e-services to the doorstep of the citizen.

The Department of Agricultural Extension (DAE) is considered as the most prominent public organization in Bangladesh for disseminating agricultural information to the farmers. In this line, the objectives of this study were to determine the extent of effectiveness of DAE regarding their services for improving farming skill and to determine the factors affecting the effectiveness of DAE services. Data were collected from two villages of Nawabganj Upazila (sub-district) in Dinajpur district using structured interview schedule. Descriptive statistics and linear regression analysis were done to explain the data. The findings revealed that majority (70.2 %) of the farmers think that the DAE services are moderately effective for improving farmer’s skill. Among the rest of the respondents, 7.7% and 22.1 % were commented as less and high effective category respectively. The inferential analysis revealed that farmers' education, organizational participation, cosmopoliteness and time spent in farming had positive and significant contribution with effectiveness of DAE services. This means that the initiative for higher these factors would increase the effectiveness of DAE services. The extension personnel, development practitioners and other researchers may be benefited from the findings. The policy makers should also consider these important factors to increase the effectiveness of DAE regarding agricultural advisory services.

The development of new tools that could meet the demand of sustainable energy production has attracted worldwide scientific attention. Over the past few decades, significant research efforts have been carried out to efficiently reduce water to H2 (green fuel) over semiconductor photocatalysts. Numerous semiconductor photocatalysts have been employed in photocatalysis for optimum H2 production. All the techniques were chosen based on their flexibility, cost-effectiveness, and ease of availability. Recently, polymeric carbon nitride (g-C3N4) received worldwide attention in visible light photocatalysis for energy and environmental applications due to its low price, robust nature, and superior thermal stability. Nevertheless, g-C3N4 (CN) exhibits shortfalls such as high charge carrier's recombination rate and weak reduction ability. To overcome these drawbacks, herein, for the first time we have fabricated B-TiO2/MIL-53(Fe)/CN ternary composite via hydrothermal and wet-chemical methods. The resultant B-TiO2/MIL53(Fe)/CN ternary composite shows drastically improved photocatalytic activity for hydrogen evolution compared to the bare CN, B-TiO2, and MIL53(Fe) components. The B-TiO2/MIL53(Fe)/CN ternary composite produced approximately 166.3 and 581.2 μmol h−1 g−1 of hydrogen under visible light and UV–visible light irradiations, respectively, with the assistance of co-catalyst Pt. Photo-luminescence (PL) and the fluorescence (FL) spectroscopy measurements reveal that the enhanced photoactivity is due to the greatly promoted charge carrier's separation and transfer at the interfacial contact of the well-aligned three-component systems. This work will promote the design and development of efficient photocatalyst based on CN for clean energy production and environmental purification.

It is highly desired to enhance charge separation and O

The 2021-2022 flood is one of the most serious flood events in Malaysian history, with approximately 70,000 victims evacuated daily, 54 killed and total losses were up to MYR 6.1 billion. From this devastating event, we realized the lack of extreme precipitation and flood inundation information, which is a common problem in tropical regions. Therefore, we have developed Flood-Tropical framework to provide a rapid extreme precipitation information and flood inundation mapping by utilizing (1) a cloud-computing platform, the Google Earth Engine (GEE); (2) open-sources satellite images such as Global Precipitation Mission (GPM), Sentinel-1 SAR and Sentinel-2 optical; and (3) flood victim information. The preliminary results on the 2021-2022 Malaysia flood were satisfactory, as the accuracy of inundated floods was up to 70%. Overall, two precipitation peaks resulted 60000 to 70000 people mostly in Selangor and Pahang evacuated on 21 – 24 December 2021, and 10000 to 15000 people from southern Peninsular evacuated on 2 – 6 Jan 2022. Extreme daily precipitation of up to 230 mm/day was observed and resulted in an inundated area of 77.43 km² in Peninsular Malaysia. This framework can act as a useful tool for local authorities to visualize extreme precipitation and floods for rescue planning and flood management.

Aim: To explore the students' opinion about the learning of the cognitive domain of the course learning outcomes studied through online learning methodology. Methods: A structured questionnaire containing eleven questions regarding the cognitive domain of course learning outcomes has been distributed among the willing participants who are studying in the college of medicine. The completely filled questionnaires were evaluated.

The conceptual model seems to be an integral part of academic research. Any conceptual model should be developed based on theoretical reasoning and practical relevance of the topic. However, for most instances, climate change adaptation studies do not ground on such rationale and relevance. A relatively lower R2 value of such studies further indicates a lack of care for developing the conceptual modelling of the study. Thus, the current study attempted to propose a conceptual model for assessing the determinants of farmers’ adaptation to climate change in Bangladesh. A three-stage approach was used in constructing the model. First, relevant literatures were collected and analysed. Second, a list of factors compiled from the first stage (i.e., analysis of literature review) was refined using the Delphi method. Finally, the result of the Delphi method was cross-evaluated by Focus Group Discussion (FGD). Based on this, the present study proposes a multi-dimensional conceptual model that includes personal, economic, institutional and environmental determinants and might influence farmers’ adaptation decision to climate change. This finding is expected to be suitable, in particular, for Bangladesh and other developing countries in general. Most importantly, it is expected to guide future research in assessing the factors influencing farmers’ adaptation strategies to climate change effect and other similar events such as adopting agricultural technologies.

Coeliac disease (CD) is a gluten-induced enteropathy affecting 1% of the population and has extra intestinal manifestations. One such expression involves nervous system, and CD may present as gluten ataxia (GA), peripheral neuropathy and epileptiform disorder among others. Considerable controversy exists on the exact pathophysiological mechanism of gluten leading to ataxia. It is, however, clear that in intestinal axis tissue transglutaminase 2 (tTG2) is the primary target but in the nervous system, tTG6 may be the causative antigen although its exact role is not clear. Furthermore, it has also been postulated that anti-gangliodise antibodies may play a role in the emergence of central pathology if not the key contender. Moreover, the association of neurological injury with non-coeliac gluten sensitivity (NCGS), a related but pathologically different condition implies an independent mechanism of neuronal injury by gluten in the absence of CD. This review will touch on the salient features of CD and the nervous system and will highlight current controversies in relation to gluten and GA.

Introduction: Remdesivir is among the investigational drugs which show some promising effect against COVID-19, it may be due to its broad-spectrum antiviral action against some RNA viruses. To date very few clinical studies have been conducted on the use of remdesivir to the treatment of COVID-19. The main objective of the present study was, to conduct a review on the effect of Remdesivir to the treatment of COVID-19. To the best of our knowledge, this is the first systematic review on the effect of remdesivir drug to the treatment of COVID-19. Methodology: We have searched PubMed, for published studies on assessing the effect of remdesivir drug among patients with confirmed COVID-19. The main search terms used were “COVID-19” or “SARS-CoV-2”, “remdesivir”, and “systematic review”. Results: Only 11 research articles were found eligible for enclosure in this systematic review, among selected studies only two were randomized, placebo-controlled trial of intravenous remdesivir. Data on the efficacy of remdesivir in the patients with confirmed COVID-19 from clinical Phase-III trials are still pending. Recently, in the latter half of May month, results of two hospital based randomized, double-blind, placebo-controlled phase III trials studies were reported, both the studies found that remdesivir was efficient in the treatment of patients with confirmed COVID-19. However, Wang et al., (2020) found that remdesivir treatment was not significantly associated with clinical benefits. Conclusion: From the systematic review, the use of remdesivir to cure patients with confirms COVID-19 was found promising; however, further clinical studies with large patient size need to be considered. The efficacy and safety of remdesivir in the treatment of COVID-19 will require to be emphasized in future research studies.

Aim: The present study was undertaken with the aim to standardize ultrasound measured urinary bladder wall thickness (UMUBWT) as an additional routine noninvasive test to assess the bladder outflow obstruction (BOO) and to monitor the therapeutic effects of BOO in follow-up after surgical correction of obstruction. Methods: This is an interventional study (pretest-posttest type of clinical trial) conducted between December 2012 to May 2015 where sample size was 55 and sampling technique was purposive. In BOO patient transabdominal sonography was performed using a 7.5 MHz. probe. The thickness of the anterior bladder wall at the midline was measured in both preoperative and postoperative period ( three months after operation) at 3 points approximately 1 cm apart and the average value was recorded. Results: In this study age range was 21-73 years with mean±SD of age was 48.76±15.08 years. In BOO patient preoperative UMUBWT was 0.51 ± 0.16 cm and which reduced to 0.26 ± 0.05 cm three months after surgical correction of obstruction. Conclusion: UMUBWT is a noninvasive, cheap and easily available additional diagnostic tool for detecting BOO as well as it can measure the therapeutic effects in postoperative period.

A 28 years old male with well developed secondary sexual characteristics was admitted in BSMMU with a grossly swollen, malformed phallus and passage of urine mostly through an opening in the perineum. After birth, his parents noticed that when the baby micturates the phallus is swollen and few drops of urine comes out through the external urethral meatus but most of the urine comes out through an opening in the perineum. No treatment was taken by his parents for this complaint. At puberty his secondary sexual characteristics developed normally. He felt sexual urge towards females but his penis was not erected. At the peak of his sexual excitement, orgasm occurs with release of whitish seminal fluid which comes mostly through perineal opening. His general physical examination was unremarkable & examination of the genitalia revealed well developed scrotum. Both of the testes were normal in size, shape and consistency but the penile shaft was large and flabby, and the ventral aspect of the penis appeared as a sac with mild pseudo phimosis. Careful palpation suggested the absence of the corpus spongiosum & corpora cavernosa. Both these findings were subsequently confirmed by a duplex colour doppler study. The penis distended ventrally when he tried to micturate and the urinary stream was narrow. About 75% of urine flow evacuates through perineal opening which was located about 2 cm from anal opening in the midline ventrally. A voiding cystourethrogram revealed that whole of the anterior urethra was grossly dilated with narrowing at the bulbar part & external urerthral meatus. There was another passage (about 5 cm) from the scrotal margin up to proximal posterior urethra. Cystogram showed a bladder diverticulum at left lateral wall. An urethrocystoscopic examination revealed that just proximal to the stenosed external urethral meatus the urethra is widely dilated which seemed like a transparent fusiform sac with irrigating fluid. Whole of the anterior urethra was very thin walled with transmitting lights through it. Proximal part of the urethra near the external sphincter was grossly narrowed. Urethrocystoscope was also introduced through the abnormal urethral opening into the perineum which was located in the midline raphe of the perineal region about 2 cm from the anal verge. This urethra joined with the penile urethra distal to the external sphincter. Prostatic part of the common urethral channel was normal containing verrumontanum and a normal bladder neck.

This paper presents an experimental analysis of heat transfer using different shaped fills in a counter flow induced draft cooling tower. The main objective is to determine and compare the characteristics of the cooling tower using newly shaped (splash and film) fills and the regular used fills. The newly shaped fills are inverted U-shape cross-sectional splash fill and film fill with ripple plates. The obtained results show that the performance is affected by the type and arrangement of the fills. The modified splash fill has increased the wetted surface area of fill within the same volume compared to regular fills. The film fill with ripple plates has been used such that water from the distribution device ran down on both surfaces of each ripple plate. By the arrangement of ripple plates, cooling loss by premature dropping off of water has been avoided. Performance factors like range, approach, effectiveness, cooling capacity, evaporation loss, percent loss are calculated from collected data for newly shaped fills, and regular shaped fills. It is observed that range, effectiveness, and cooling capacity increases with both newly shaped fills. When ripple plated film fill is used; range, effectiveness, and cooling capacity is found highest among the different shape of fills used in this study. At the same time evaporation loss and percent loss are found lowest for inverted-U shaped splash fill.

Hypohidrotic ectodermal dysplasia (HED) is a congenital anomaly characterized by hypohydrosis, hypotrichosis and hypodontia. Mutations in at least four genes (EDAR, EDARADD, WNT10A, TRAF6) have been reported to cause both autosomal recessive and autosomal dominant forms of HED. Mutations in two other genes (EDA and IKBKG) have been reported to cause X-linked HED. To clinically characterize three consanguineous families (A-C) segregating with autosomal recessive HED and identify possible disease-causing variants of EDAR and EDARADD genes. The genes, EDAR and EDARADD, were sequenced in Family A and C, and exome sequencing was performed in Family B. Additionally, in Family A and C, the effect of the identified variants was examined by analysis of EDAR mRNA, extracted from hair follicles from both affected and unaffected members. Sequence analysis revealed three possible disease-causing EDAR variants including a novel splice acceptor site variant (IVS3-1G > A) in Family A and two previously reported mutations (p.[Ala26Val], p.[Arg25*]) in the two other families. Previously, the nonsense variant p.(Arg25*) was reported only in the heterozygous state. Analysis of the RNA, extracted from hair follicles, revealed skipping of a downstream exon in EDAR and complete degradation of EDAR mRNA in affected members in family A and C, respectively. Computational modelling validated the pathogenic effect of the two variants identified in Family B and C. The three variants reported here expand the spectrum of EDAR mutations associated with HED which may further facilitate genetic counselling of families segregating with similar disorders in the Pakistani population.

Objective: To explore the in vitro pharmacological activities of fruit of Diospyros malabarica. Method: 70% ethanolic extracts of Diospyros malabarica was screened against ten pathogenic bacteria, five strains of gram +ve, five strains of gram –ve bacteria and fungi by using disc diffusion method. Moreover, to study the toxicity of this fruit, we conducted a saltwater shrimp lethality bioassay based on the ability to kill laboratory cultured brine shrimps (Artemiasalina). Results: Fruits extracts were found to exhibit antimicrobial activity against bacterial pathogens with the zone of inhibition ranges between 13mm to 19mm. Fruit Extracts was also tested for its antifungal activity against fungal strains exhibiting zone of inhibition ranges from 14 mm to 19 mm. The fruit extract of Diospyros malabarica shows significant lethality towards brine shrimps at LD50 value of 93.55 ppm. Conclusion: Plant extracts is potentially effective in suppressing microbial and fungal growth. As fruit extracts has significant LD50 value thus it can be further used for cancer cell line studies.

It is a great challenge to prepare chip thermistors with high positive temperature coefficient of resistivity (PTCR) jump and simultaneously low room temperature resistivity by reduction-reoxidation method. In this work, the influence of Mn doping on Ba0.996La0.004(Bi0.5Na0.5)0.003TiO3 based chip thermistors were carefully investigated and Mn doping was proved to be an effective way in preparation of high-performance PTCR ceramics with low resistivity. The results showed that Mn can't create a high enough potential barrier in un-oxidized samples but can obviously increase the value of potential barrier height after reoxidation. The trap activation of Mn d states near Curie point helps to reduce room temperature resistivity and increase PTCR jump in reoxidized samples. As a result, samples with extremely low resistivity and high PTCR jump of 103.4 were reported for the first time.

Herein, powder samples of Cd/Fe co-doped ZnO nanoparticles have been synthesized via sol-gel route. The impact of co-doping on physical properties of the samples is examined by various techniques. The XRD patterns show that the samples possess hexagonal wurtzite structure of the parent ZnO. In photoluminescence spectra, red and blue shifts observed for near-band-edge UV emission and green-band (GB) emission, respectively, confirming substitutional incorporation of Cd/Fe into the ZnO lattice. The Cd/Fe co-doped ZnO gives superior electrochemical activities because of high charge collection and facilitate the electrons at the interfaces of doped ZnO and the electrode layer. Mossbauer studies reveal that disorders enhance close to Fe3+ as Cd/Fe co-doping increases. C3F3 sample shows higher ΔD1 compared to the other samples, suggesting that more Fe3+ exist close to the defective sites. The disk diffusion method was used for antibacterial performance of two bacteria Pseudomonas aeruginosa (P. aeruginosa) and Bacillus flexus (B.flexus). C2F2 shows the highest antibacterial activates among all samples.

The study was undertaken to assess the extent of the area used for tobacco cultivation and to determine some selected characteristics of tobacco farmers that significantly influence farmers’ cultivation of tobacco. The selected characteristics were- age, education, farm size, annual income, tobacco cultivation experience, family labor, time spent in tobacco cultivation, profitability, agent contact, input availability, level of pest infestation and market security perception. The study was conducted at three villages of Mirpur upazilla under Kushtia district with the help of an interview schedule from September 12 to October 3, 2018. Twenty-five percent (25%) of the farmers were randomly selected from a population of 424 tobacco farmers. Out of the total population, 106 tobacco farmers were selected as the sample of the study. Multiple linear regressions were used in order to identify the important factors for tobacco cultivation. The findings also revealed that age, education, annual income, family labor and agent contact have a significant positive contribution to tobacco cultivation. Therefore, to reduce tobacco cultivation area coverage by the farmers, the policy should be made by giving emphasize on the significant factors.

A common challenge forward-looking utilities are facing when deploying advanced applications that facilitate voltage optimization and service restoration is to provide adequate sensor data for a Distribution System State Estimator (DSSE) so that it provides sufficiently accurate estimates of the system states to enable these applications in an operational environment. We developed a stochastic method that informs telemetry and operational forecasting requirements by quantifying the DSSE performance in supporting advanced applications. The performance metric used is the $\alpha $ risk, which is the likelihood of a DSSE giving a false positive when determining if voltage and loading constraints are met. We applied this method to six real-world industrial/commercial/residential distribution circuits and evaluated $\alpha $ risk improvements provided by circuit-level sensors and operational forecasting. The results show that a combination of sensor deployment schemes was needed to reduce the $\alpha $ risk for undervoltage to effectively zero. Also, sensors deployed at large loads significantly reduce $\alpha $ risks on industrial/commercial circuits while operational forecasting consistently reduces $\alpha $ risks on all circuits. The practical method does not require advanced mathematics and can be readily used by utilities to inform grid modernization investments in sensor technologies so that advanced applications can be executed optimally and violation-free.

Agricultural mechanization has the potential to greatly increase cropping intensity and production. The identification of factors that influence adoption and dis-adoption will assist policymakers in filling knowledge gaps, allowing for more successful policy implementation in Bangladesh. As a result, this study was carried out to ascertain the factors influencing the adoption and dis-adoption of rice-wheat threshers in Bangladesh. The International Food Policy Research Institute's (IFPRI) Bangladesh Integrated Household Survey (BIHS) data were used in the analysis. A total of 5605 households were selected to fulfill the objectives, and a bivariate probit model was employed. According to the findings, 52.41% households adopted the thresher, with 13.75% abandoning it later. When compared to non-adopters, farmers with larger farm sizes and regular extension contacts were 31% and 33% more likely to adopt. Dis-adoption analysis, on the other hand, revealed that the chance of dis-adoption was 9.3% lower for households that maintained contact with extension officers as compared to their counterparts. Demand-driven extension services have the ability to promote adoption while lowering dis-adoption. Farmer-based groups and technology-based extension initiatives can help to keep adoption going.

Broussonetia papyrifera (B. papyrifera) is an allergenic plant in the mulberry family that grows at varied elevations and climatic conditions worldwide. In northern Pakistan, B. papyrifera is abundant and it produces a substantial amount of pollen that disperses in the air causing allergies in some humans. Climate change affects pollen production. To investigate potential changes in pollens development and potential allergenicity, B. papyrifera pollens were collected in summer and in spring from different regions in Pakistan. Study samples were subjected to morphological analysis, Fourier Transform Infrared Spectroscopy (FTIR) analysis for biochemical differences, and Liquid Chromatography-Mass Spectrometry (LCMS) for metabolome analysis. Morphological studies of the dried pollen by light microscopy showed seasonal and regional differences in pollens size and exine morphology. FTIR analysis showed inter-regional and inter-seasonal differences in the metabolome of the pollen. Differences in lipid and protein functional groups of pollen from different regions showed variation in the FTIR spectra. These differences in FTIR spectra correlated with the changing climatic conditions. Metabolome analysis of targeted pollen samples identified 33 organic compounds of seven different groups. Four unsaturated fatty acids were identified that have a potential role in allergic responses. The findings in this study are unique in demonstrating climatic variables that effect B. papyrifera pollen physiology (FTIR analysis) which also confirms differences in pollen-associated lipid metabolites identified by LCMS analysis. These results demonstrate information that may be used to predict potential changes in allergy risks from pollens of B. papyrifera in the future. The findings may provide a model for predicting variation in pollen structure and associated allergies in response to climate changes for other species.

Ever since the dawn of human life on this planet, man has always sought to understand Nature, his own place in the scheme of creation and the purpose of life itself. Religion played a vital role in shaping the human life and aligning the socio-cultural behaviors. After the beginning of Prophetic Mission in 610 C.E., the Prophet Muhammad PBUH and his companions started preaching of Islam in Arab and beyond the Arab boundaries afterwards. During this Prophetic Mission of preaching Islam, the Holy Prophet PBUH and his companions faced different social and economical problems in order to stop this mission. Specially, in the era of Makkan life of the Holy Prophet PBUH. He adopted different strat-egies to get rid of these hurdles and problems. He also laid down basic principles in order to continue the Prophetic Mission in this scenario. A discussion is prem-editated to explore the principles set by the Holy Prophet PBUH for preaching of Islam in this scenario. In this article, a discussion about the Terminology of "Hikmah" is described along with some practical examples also.

A typical Z-scheme system is composed of two photocatalysts which generate two sets of charge carriers and split water into H2 and O2 at different locations. Scientists are struggling to enhance the efficiencies of these systems by maximizing their light absorption, engineering more stable redox couples, and discovering new O2 and H2 evolutions co-catalysts. In this work, Au decorated WO3/g-C3N4 Z-scheme nanocomposites are fabricated via wet-chemical and photo-deposition methods. The nanocomposites are utilized in photocatalysis for H2 production and 2,4-dichlorophenol (2,4-DCP) degradation. It is investigated that the optimized 4Au/6% WO3/CN nanocomposite is highly efficient for production of 69.9 and 307.3 µmol h−1 g−1 H2 gas, respectively, under visible-light (λ > 420 nm) and UV–visible illumination. Further, the fabricated 4Au/6% WO3/CN nanocomposite is significant (i.e., 100% degradation in 2 h) for 2,4-DCP degradation under visible light and highly stable in photocatalysis. A significant 4.17% quantum efficiency is recorded for H2 production at wavelength 420 nm. This enhanced performance is attributed to the improved charge separation and the surface plasmon resonance effect of Au nanoparticles. Solid-state density functional theory simulations are performed to countercheck and validate our experimental data. Positive surface formation energy, high charge transfer, and strong non-bonding interaction via electrostatic forces confirm the stability of 4Au/6% WO3/CN interface.
