Abstract

In the simple buildings, shallow foundations can be used to support the construction above them. This shallow foundation has various types, including the type of footplate which can be calculated using the Terzaghi equation. In the Terzaghi equation, it requires dimension parameters of the footing and soil material parameters such as cohesion and soil volume weight which requires laboratory testing to obtain it. Meanwhile, Schmertmann provides an equation to obtain the Terzaghi bearing capacity factor in the form of Nq and Nγ by using the Cone Penetration Test (CPT). This bearing capacity factor value can be used to calculate the bearing capacity using the Terzaghi Equation. In addition, Schmertmann also provides an equation to directly calculate the bearing capacity value based on CPT data. Based on this problem, this study analyzes the bearing capacity of various footplate dimensions using the Schmertmann approach. The study took place in the Argoboga, Salatiga which the type of soil based on the CPT test value generally is sandy soil. The results show that the bearing capacity calculated by the Nq correlation method is greater than the Nγ correlation method and the direct correlation method. In addition, the greater the difference between the dimensions and the depth of the foundation, the greater the deviation of the bearing capacity results between each method.

Abstract

Shear walls in high-rise buildings serve to increase the resistance of high-rise buildings to lateral loads. This study aims to compare the structural performance of an existing 8 (eight) storey building designed as a special moment resisting frame structure against a building designed as a dual system, which consists of: structural vibration time, base shear force, displacement, and drift. Three configurations for shear walls are designed, as follows: (1) L-shaped located at the corner of one side of the building, totaling 2 (two) units (SW1); (2) L-shaped located at the four corners of the building totaling 4 (four) units (SW2); and 3) I-shaped located along the side of the building totaling 6 (six) units (SW3). Simulations are run using the Etabs by taking into account dead loads, live loads, and earthquake loads. The results show that the addition of shear walls can: (1) reduce the vibration period of the structure up to 62,55% in SW3, (2) increase the base shear force up to 86,34% in SW3, (3) reduce peak displacement up to 84,86% in SW3, and (4) reduce the drift between floors up to 89,58% in SW3. However, the SW2 is considered to be better applied to the building by taking into account the structural performance, effectiveness and efficiency factors.

Abstract

Introduction Savory plant (Satureja bachtiarica) belonging to the Lamiaceae family and the genus Satureja is considered as a valuable medicinal plant. Flowering branches are widely used in food and pharmaceutical industries. This plant is native of Iran and grows well in the western, southwestern and central regions of Iran. Cultivation of permanent medicinal plants adapted to the dryland farming conditions of each region can be the best option for alternative annual cereal cultivation. Establishment of permanent medicinal plants, while creating suitable vegetation, can prevent erosion caused by repeated annual plowing. One of the main pillars in sustainable agriculture is the use of organic fertilizers in crop ecosystems with the aim of eliminating or significantly reducing the harms of chemical fertilizers. Organic fertilizers help to human health and environment. Also it is absolutely evident the importance of their application to medicinal plants that are directly related to human health. In dryland farming condition, plant density is an effective strategy to improve plant yield, which depends on climate and rainfall. At optimum density, plants make the most of environmental factors such as light, moisture, and nutrients. Plant density per unit area is one of the important factors in creating competition among plants. The appropriate distance between planting rows and between plants on the row are usable growth space of each plant. Proper density is one of the important factors in the success of dry farming of medicinal plants. Therefore, achieving proper density in different areas is very important. Materials and Methods An experiment was conducted as a split plot based on randomized complete block design with three replications at Homand rangeland research station of Damavand in 2017 and 2018 in dryland farming conditions. Organic fertilizer as a main factor included three levels of cattle manure (30 tons ha-1), wheat straw (10 tons ha-1) enriched with ammonium sulfate, and control (no fertilizer). Plant density included three levels of 26666, 40000, and 80000 plants ha-1 as a sub-factor. Measured traits included plant height, canopy area, number of main branches, shoot dry matter yield, percentage of dry weight to fresh weight of plant, and percentage of moisture to dry soil at 0-20 and 20-40 cm depths. Analysis of variance was performed using SPSS software. The statistical significance of differences in mean values was assessed by Duncan's multiple range test. Results and Discussion The results showed significant differences between treatments in measured traits. Among the measured traits, the effect of organic fertilizer and plant density on plant height, canopy area, number of main branches, shoot dry matter yield were significant at 1% level. The interaction effect of year, organic fertilizer and plant density showed that the highest of shoot dry matter yield (426 kg ha-1) was related to cattle manure application and high plant density in second year. The highest plant height and number of main branches were observed 34 cm and 29 numbers, respectively in treatment of cattle manure and second year. Organic fertilizers increased the storage capacity of soil moisture and created suitable conditions for growth and increased the biological Satureja bachtiarica yield. Improving soil structure and nutrients and better root growth increased plant growth and yield due to the use of organic fertilizers. The plant density due to higher plant per unit area, plant competition, optimal use of available space, and also establishment and more plant growth in the second year increased significantly the Satureja bachtiarica yield. Conclusions This study showed that understanding the success of establishment and full tolerance of this plant under dryland farming conditions and the minimum soil moisture in the cold semi-steppe region (Damavand) with an average rainfall about 340 mm per year and also the use of cattle manure and high plant density can increase the economic yield of Satureja bachtiarica in second year of cultivation.

Abstract

Objectives Studies have demonstrated high rates of mortality in people with proximal femoral fracture and SARS-CoV-2, but there is limited published data on the factors that influence mortality for clinicians to make informed treatment decisions. This study aims to report the 30-day mortality associated with perioperative infection of patients undergoing surgery for proximal femoral fractures and to examine the factors that influence mortality in a multivariate analysis.Setting Prospective, international, multicentre, observational cohort study.Participants Patients undergoing any operation for a proximal femoral fracture from 1 February to 30 April 2020 and with perioperative SARS-CoV-2 infection (either 7 days prior or 30-day postoperative).Primary outcome 30-day mortality. Multivariate modelling was performed to identify factors associated with 30-day mortality.Results This study reports included 1063 patients from 174 hospitals in 19 countries. Overall 30-day mortality was 29.4% (313/1063). In an adjusted model, 30-day mortality was associated with male gender (OR 2.29, 95% CI 1.68 to 3.13, p80 years (OR 1.60, 95% CI 1.1 to 2.31, p=0.013), preoperative diagnosis of dementia (OR 1.57, 95% CI 1.15 to 2.16, p=0.005), kidney disease (OR 1.73, 95% CI 1.18 to 2.55, p=0.005) and congestive heart failure (OR 1.62, 95% CI 1.06 to 2.48, p=0.025). Mortality at 30 days was lower in patients with a preoperative diagnosis of SARS-CoV-2 (OR 0.6, 95% CI 0.6 (0.42 to 0.85), p=0.004). There was no difference in mortality in patients with an increase to delay in surgery (p=0.220) or type of anaesthetic given (p=0.787).Conclusions Patients undergoing surgery for a proximal femoral fracture with a perioperative infection of SARS-CoV-2 have a high rate of mortality. This study would support the need for providing these patients with individualised medical and anaesthetic care, including medical optimisation before theatre. Careful preoperative counselling is needed for those with a proximal femoral fracture and SARS-CoV-2, especially those in the highest risk groups.Trial registration number NCT04323644

Abstract

Self-healing concrete is a dependable construction material for cracks recovery via autonomous or autogeneous mechanisms. When bacteria react with water vapour and urea, calcium carbonate (CaCO3) particles are produced, which can repair cracks and protect concrete reinforcement. The addition of fibre to the concrete is expected to reduce crack width and play a role in the bridging mechanism in the calcium carbonate deposit in larger crack. Given the potential of these two materials, the purpose of this research is to examine the mechanical strength of concrete resulting from this bacterial-based concrete innovation, which includes compressive strength and split tensile strength. The study employs experimental methods. The test specimens were concrete with bacillus subtilis bacteria as a healing agent and fibres extracted from recycled polyethylene terephthalate (PET) fibres, and the reference specimens were the normal concrete. At the age of 28 days, all test specimens moulded in the shape of a standard concrete cylinder of 150 x 300 mm were tested using Universal Testing Machine. The results showed that using bacteria and 1% of PET reduced compressive and tensile strength by 10% and 1%, respectively, when compared to control specimens. PET has a lower material stiffness than other concrete constituent materials, so its use should be limited to achieve positive results. [ABSTRACT FROM AUTHOR]

Abstract

Construction cementitious materials or construction-based materials, such as cement paste, mortar, and concrete, are one of the most utilized materials in building construction today. This material's advantages include its high compressive strength, durability, lower labor costs, and applicability to a wide range of building applications. In its use, this material is susceptible to shrinkage, which produces a decrease in the material's volume because of reduced moisture content and loss of water during the hardening process. In a mixture of cement-based construction materials with a low water-cement ratio, superabsorbent polymer (SAP) is known to be one of the materials with "healing agent" capabilities. In addition, the usage of this material can automatically cover cracks. This study aims to examine the use of superabsorbent polymer in improving the durability of cement-based construction materials, as well as the problems that could occur if this material is applied in Indonesia. Several techniques, including data collection techniques, data reduction, data analysis, data presentation, and drawing conclusions, are used to conduct a literature review. The result of this research is a literature review on the definition of SAP, its durability, and its challenges in Indonesia. [ABSTRACT FROM AUTHOR]

Abstract

Self-healing concrete (SHC) is a concrete material innovation which can cure a crack on the concrete by microorganism supplementary as a healing agent. Besides, plastic is a material frequently utilized, yet it increases the amount of plastic waste in environment. Thus, the plastic waste has been developed as a synthetic fiber inside the concrete. Plastic waste supplementary in SHC has potential in increasing mechanic characteristics on the concrete. However, research discussing plastic waste substitution in SHC has been uncovered. This research aimed at analyzing load strength value ability accession, elasticity modulus, strength of tensile, and evaluation result resulted from crack cover of SHC Bacillus subtilis bacteria based with the substitution of plastic waste on the concrete was normal. This study employed experimental method by utilizing two compositions of concrete: A's composition (bacteria concrete and plastic fiber) and R (normal concrete). Both of compositions later would be molded consisting of 3 cylinders 150×300 mm and 3 prism 75×75×150 mm. Next, the treatment was undertaken for 28 days before testing. To evaluate the crack, the tested concretes were placed into three different treatments; indoor, outside, and immersed on water. Furthermore, the research showed the elasticity modulus value, and it decreased up to 7.75%, compared with normal concrete. The crack closure evaluation showed that crack closure in concrete by immersed on water by coverage as calcium carbonate sediment in the crack area on the 14th and 28th compared with other treatment.

Abstract

The reinforced concrete beam structure plays a role in receiving bending force and shear force so that it will undergo deformation during loading. In order to maximize the performance of the beams, reinforcement is added to help in withstanding tensile stresses because the concrete is weak against tensile. If the deflection arising from large loading results in the servisability of the beam is also less comfortable. For this reason, the rigidity of the beam needs to be designed so that the deflection of the beam can be limited. Realizing the importance of rigidity to the behavior of structures, the researchers conducted research on the behavior and characteristics of graded concrete beam. This research was conducted to determine the effect of singly and doubly reinforcement configurations on the rigidity of graded concrete beam. There were six specimens in this study. Each specimen is formed with two concrete mixtures, namely 20 MPa and 40 MPa with a beam shear span ratio of 2.5. Testing was performed numerically using the FEA application. The results showed that the behavior of single-reinforced and double-reinforced graded beams was between their control beams. Then, the double reinforced configuration on the gradation beam results in higher rigidity than the single reinforced gradation beam with an increase of up to 27.51%. The deformation ability of double reinforced gradation beams has increased by up to 38% than that of single-reinforced gradation concrete beams. In addition, with a double reinforcement configuration, the curvature of the gradation concrete beam is reduced to -2.19%. The design of the double reinforcement configuration is more recommended as a reinforcement for gradation concrete beams in subsequent studies. [ABSTRACT FROM AUTHOR]

Abstract

The expected failure of the structure is an important parameter to consider when designing reinforced concrete beams. The magnitude of tensile and compressive stresses due to loading, which is determined by the reinforcement configuration, has a large influence on structural failures. The addition of reinforcing steel can improve the resistance of reinforced concrete beams to tensile stress, but it reduces the beam's ductility. On the other hand, in recent years, reinforced concrete innovation has been developed in an effort to optimize the performance of beams by grading the quality of concrete. In comparison to normal concrete beams, reinforced graded concrete beams (RGCB) exhibit more complex behavior. Based on this, this study was carried out to investigate the effect of single and double reinforcement on RGCB. In the modeling, RGCB with concrete quality of 40 MPa on compressed fibers and 20 MPa on tensile fibers was modeled. The beam geometry is b=179 mm, h=358 mm, and the a/d ratio is 2.5. All specimens of the test object are designed with a low rebar ratio in the expectation that the beam will be ductile. The study's findings are as follows: (1) the crack pattern created on the RGCG resembles a higher quality control concrete beam; (2) RGCB experience bending failure in the middle of the span followed by shear failure; (3) the use of different concrete strengths in RGCB creates an unsustainable cracking pattern; and (4) the use of double reinforcement on RGCG shows more distributed strain propagation compared to RGCG with single reinforcement.

Abstract

Optical Character Recognition (OCR) research includes computer vision, artificial intelligence, and pattern recognition. Character recognition has garnered a lot of attention in the last decade due to its broad variety of uses and applications, including multiple-choice test data, business documents (e.g., ID cards, bank notes, passports, etc.), and automatic number plate recognition. This paper introduces an automatic recognition system for printed numerals. The automatic reading system is based on extracting local statistical and geometrical features from the text image. Those features are represented by eight vectors extracted from each digit. Two of these features are local statistical (A, A th), and six are local geometrical (P1, P2, P3, P4, P5, and P6). Thus, the database created consists of 1120 statistical and geometrical features. For the purpose of recognition, the features of the test image are compared with the features of all the images saved in the database depending on the value of the Minimum Distance (MD). All digits (0–9) were identified with 100% accuracy. The average computational time required to recognize a numeral at any font size is 0.06879 seconds.

Abstract

Concrete is the largest contributor to carbon emissions in the construction sector. However, recently there have been no studies analyzing embodied carbon in normal concrete with specific reviews on one structural element and reinforced concrete buildings with variations in structural configuration. The purpose of this study is to determine the influence of material variables and designs of reinforced concrete beam and reinforced concrete buildings on the value of embodied carbon which can then be used as a consideration of low-emission building design. This research was conducted using parametric analysis methods using Building Information Modeling-based applications and ICE Cement, Mortar, and Concrete Model – V1.1 Beta. Reinforced concrete beam were designed with single reinforcement with minimum and maximum reinforcement ratio and in cross-sectional dimension ratios, namely 1:3, 1:2, and 2:3. Reinforced concrete buildings were designed with 3 variations of column elevation, namely 3000 mm, 3500 mm, 4000 mm, and 3 variations in beam span, namely 3000 mm, 4000 mm, 6000 mm. The results of this study show that the greater the ratio of width to height of the beam (b/h) and the reinforcement ratio, the higher the embodied carbon produced. The denser and higher the elevation of the column used, the greater the embodied carbon produced. In reinforced concrete buildings, the cradle-to-gate stage produces embodied carbon by 49.69%, the construction stage by 2.93% and End of Life by 4.39%. [ABSTRACT FROM AUTHOR]

Abstract

Based on the empirical equation, the calculation of the bearing capacity of the pile foundation is influenced by the characteristics of the soil indicated by the cone resistance and friction (CPT) and the SPT value. However, determining the bearing capacity is also influenced by the material parameters of the foundation used. Based on SK SNI T-15-1991-03 [1] and ACI 363-92 [2], the determination of the concrete elasticity modulus is influenced by density, concrete compressive strength, and the correction factor. The value of this parameter can affect the bearing capacity and the settlement. Based on this, this study analyzes the behavior of driven single concrete piles at a diameter of 400 mm on the downward and uplift bearing capacity and the settlement with the variation of concrete compressive strength. This parameter can affect the elasticity modulus and the density of the material. The analysis was carried out using the Allpile program and empirical equation. The pile was reviewed at depth of 8 meters on clay soil. The results show that the downward bearing capacity is not affected by the weight, density, concrete compressive strength, and elasticity modulus (pile parameter material). Meanwhile, the result of the uplift bearing capacity is influenced by the alteration in the weight and density which affect the compressive strength and elasticity modulus. The value of the elasticity modulus affects the settlement of the foundation. The relationship that results in a corresponding point between weight, settlement, and uplift bearing capacity occurs approximately at 2.78 kN/m, 0.032 cm, and 94.6 kN. [ABSTRACT FROM AUTHOR]

Abstract

Detecting small objects using computer vision is a challenging task due to their small size in the image and therefore the lack of features when describing them. In this paper, a computer was trained to detect three small balls using 20 levels of the AdaBoost cascade classifier. The features of the balls in each level are described using the HOG feature descriptor. Three balls were recorded in practice at various distances (d = 2, 3, 4, ..., 10 m) from the camera and the targets (balls). The frames are then taken from the videos and resized using five magnification factors (RS = 1, 3, 5, 7, and 9) to make the balls seem as they should. According to the results, the detection rate of balls at all distances was 80% when using the magnification factor RS = 1, 90% when using the magnification factor RS = 3, 5, and 7, and 100% when using the magnification factor RS = 9. The suggested approach was also used in calculating the height and width of the detected balls. The overall results indicated that the height and width of the balls dwindle as the distance between the camera and the targets increases.

Abstract

Policy Points American health care policy must be critically assessed to establish the role it plays in sustaining and alleviating the health disparities that currently exist in molecular genetic testing. It is critical to understand the economic and sociocultural influences that drive patients to undergo or forgo molecular testing, especially in marginalized patient populations. A multipronged solution with actions necessary from multiple stakeholders is required to reduce the cost of health care, rebalance regional disparities, encourage physician engagement, reduce data bias, and earn patients' trust.The health status of a population is greatly influenced by both biological processes and external factors. For years, minority and low socioeconomic patient populations have faced worse outcomes and poorer health in the United States. Experts have worked extensively to understand the issues and find solutions to alleviate this disproportionate burden of disease. As a result, there have been some improvements and successes, but wide gaps still exist. Diagnostic molecular genetic testing and so-called personalized medicine are just now being integrated into the current American health care system. The way in which these tests are integrated can either exacerbate or reduce health disparities.We provide case scenarios-loosely based on real-life patients-so that nonexperts can see the impacts of complex policy decisions and unintentional biases in technology without needing to understand all the intricacies. We use data to explain these findings from an extensive literature search examining both peer-reviewed and gray literature.Access to diagnostic molecular genetic testing is not equitable or sufficient, owing to at least five major factors: (1) cost to the patient, (2) location, (3) lack of provider buy-in, (4) data-set bias, and (5) lack of public trust.Molecular genetic pathology can be made more equitable with the concerted efforts of multiple stakeholders. Confronting the five major factors identified here may help us usher in a new era of precision medicine without its discriminatory counterpart.

Abstract

Context.— Myriad forces are changing teaching and learning strategies throughout all stages and types of pathology education. Pathology educators and learners face the challenge of adapting to and adopting new methods and tools. The digital pathology transformation and the associated educational ecosystem are major factors in this setting of change. Objective.— To identify and collect resources, tools, and examples of educational innovations involving digital pathology that are valuable to pathology learners and teachers at each phase of professional development. Data Sources.— Sources were a literature review and the personal experience of authors and educators. Conclusions.— High-quality digital pathology tools and resources have permeated all the major niches within anatomic pathology and are increasingly well applied to clinical pathology for learners at all levels. Coupled with other virtual tools, the training landscape in pathology is highly enriched and much more accessible than in the past. Digital pathology is well suited to the demands of peer-to-peer education, such as in the introduction of new testing, grading, or other standardized practices. We found that digital pathology was well adapted to apply our current understanding of optimal teaching strategies and was effective at the undergraduate, graduate, postgraduate, and peer-to-peer levels. We curated and tabulated many existing resources within some segments of pathology. We identified several best practices for each training or educational stage based on current materials and proposed high-priority areas for potential future development.

Abstract

Morgan, B, Mirza, AM, Gimblet, CJ, Ortlip, AT, Ancalmo, J, Kalita, D, Pellinger, TK, Walter, JM, and Werner, TJ. Effect of an 11-week resistance training program on arterial stiffness in young women. J Strength Cond Res XX(X): 000-000, 2022-The current investigation was conducted to determine the effect of 2 resistance training models on indices of arterial stiffness in young, healthy women. Twenty-four women, untrained college students, aged 18-22 years were randomized into 1 of 3 groups: control (CON) group (n = 8), high-intensity (HI) resistance exercise group (n = 8), and high-volume (HV) resistance exercise group (n = 8). Subjects randomized to resistance training groups were required to perform strength training exercises 3-5 days a week for 11 weeks. The exercise regimen consisted of 2-3 sets of 3-8 repetitions (80-90% of 1 repetition maximum [1RM]) for the HI group and 3-4 sets of 10-15 repetitions (50-70% of 1RM) for the HV group. All subjects were instructed to continue their normal diet and avoid cardiovascular exercise during the study. After the intervention, there was a significant increase in carotid femoral pulse wave velocity (PWV) (6.39 ± 0.73 to 8.40 ± 2.31 m·s-1; p0.05) and carotid radial PWV (9.77 ± 1.74 to 12.58 ± 2.09 m·s-1; p0.05) in the CON group alone. Both the HI and HV groups increased their maximum squat (36.6 ± 7.9 vs. 41.3 ± 31.8 percent change; p0.05), bench press (34.4 ± 12.6 vs. 23.4 ± 11.1 percent change; p0.05), and seated row (22.0 ± 12.6 vs. 21.9 ± 12.5 percent change; p0.05), respectively. Our findings support the use of resistance training exercise without undue impact on vascular compliance in otherwise healthy women.

Abstract

The examination of morphological alterations in tissues is fundamental in Pathology. Traditional training in gross dissection has several limitations, including the risk of transmissible diseases, formaldehyde exposure and limited specimen availability. We describe a teaching method using anatomical simulators.Liquid silicone-based artisan neoplastic anatomical models were used in conjunction with clinical scenarios. Eighty-five medical students participated in a gross dissection experience and were asked to complete a feedback questionnaire. Additionally, a workshop was organized for students to compare three different teaching methods. The first one used still images (Group1-G1), the second a video explanation (Group2-G2), and the third directly observed a pathologist while grossing (Group3-G3).The knowledge acquisition questionnaire showed an average value of 4.4 out of 5 (1-5) (range 3.4-4.7, σ0.89). The categories 'knowledge of resection margins' and 'macroscopic diagnosis' received the highest values (4.8, σ0.11 and 4.7, σ0.32, respectively), followed by 'understanding of handling and gross examination of the surgical specimen' (4.5, σ0.49), 'prognosis' (4.3, σ0.67) and 'understanding of a tumor resection' (3.9, σ0.96) (p0.05). Regarding teaching methods, G3 spent less time than G2 and G1 with mean times of 15'39″ (σ2'12″), 16'50″ (σ3'45″), and 17'52″ (σ2'12″), respectively (p0.05). Gross dissection marks (0-5) showed statistically significant differences (p0.05). G2 obtained better results (3.7;σ0.54) than G3 (3.4;σ0.94) or G1 (3.1;σ0.8).This preliminary study demonstrates that it is possible to implement a gross dissection simulation module at medical school and thus enable the acquisition of skills in a secure environment.

Abstract

Beton merupakan material penyumbang emisi karbon terbesar pada sektor konstruksi. Namun hingga saat ini belum ada penelitian yang menganalisis embodied carbon pada beton normal dengan variasi metode pencetakan tinjauan spesifik pada satu elemen struktur dan bangunan beton bertulang dengan variasi konfiguasi struktur. Tujuan penelitian ini yaitu dapat diketahuinya pengaruh variabel material dan desain beton balok beton bertulang dan bangunan beton bertulang terhadap nilai embodied carbon yang selanjutnya dapat digunakan sebagai pertimbangan desain bangunan rendah emisi. Penelitian ini dilakukan dengan metode analisis parametrik menggunakan aplikasi berbasis Building Information Modeling yaitu Tekla Structural Designer 2022 Educational Version dan ICE Cement Mortar and Concrete Model ndash V1.1 Beta. Beton didesain dengan 5 variasi mutu dan 2 metode pencetakan. Balok beton bertulang didesain dengan tulangan tunggal kondisi rasio pembesian perlu dan rasio pembesian maksimum dengan 3 variasi rasio dimensi penampang (b/h) yaitu 1 3 1 2 dan 2 3. Bangunan beton bertulang didesain dengan 3 variasi elevasi kolom yaitu 3000 mm 3500 mm 4000 mm dan 3 variasi jarak antar kolom yaitu 3000 mm 4000 mm 6000 mm. Hasil dari penelitian ini menunjukan bahwa seiring bertambahnya mutu beton maka semakin besar pula embodied cabon yang dihasilkan. Beton dengan metode pencetakan pra cetak menghasilkan embodied carbon yang lebih besar dengan persentase selisih berkisar antara 7 6% - 9 51% pada mutu yang bersesuaian. Semakin besar rasio lebar terhadap tinggi balok (b/h) dan rasio pembesian yang digunakan maka semakin tinggi pula embodied carbon yang dihasilkan balok beton bertulang baik pada perhitungan teoritis dan pendekatan lapangan. Peningkatan embodied carbon pada setiap rasio dimensi penampang yang digunakan terhadap rasio pembesian berkisar antara 37-56% pada perhitungan teoritis dan 46-61% pada pendekatan lapangan. Semakin rapat dan tinggi elevasi kolom yang digunakan maka semakin besa

Abstract

Static hand gesture recognition is critical in the development of a system for human-computer interaction. Many human-computer interactions, such as human-robot interaction, game control, control of smart home devices, and others, use hand gestures as a fundamental and natural language of the body. The direction of rotation of static hand gestures is the subject of this research, and the focus is on six degrees of rotation (0°, 45°, 90°, 180°, 270°, and 315°). This work presents an ideal approach that can recognize the angle of hand gestures based on the Aggregate Channel Features (ACF) detector. This approach consists of three main stages: preprocessing (image labelling), computer training, and hand angle detection based on the ACF detector. The training process consists of 25 stages. The static hand gesture dataset contained 569 images (361 for training and 208 for testing). The average time cost to detect all hand gesture angles was 0.9445 seconds, and all hand angles were recognized with 100% accuracy. This is a strong indication that supports our approach.

Abstract

The World Wide Web comprises of huge web databases where the data are searched using web query interface. Generally, the World Wide Web maintains a set of databases to store several data records. The distinct data records are extracted by the web query interface as per the user requests. The information maintained in the web database is hidden and retrieves deep web content even in dynamic script pages. In recent days, a web page offers a huge amount of structured data and is in need of various web-related latest applications. The challenge lies in extracting complicated structured data from deep web pages. Deep web contents are generally accessed by the web queries, but extracting the structured data from the web database is a complex problem. Moreover, making use of such retrieved information in combined structures needs significant efforts. No further techniques are established to address the complexity in data extraction of deep web data from various web pages. Despite the fact that several ways for deep web data extraction are offered, very few research address template-related issues at the page level. For effective web data extraction with a large number of online pages, a unique representation of page generation using tree-based pattern matches (TBPM) is proposed. The performance of the proposed technique TBPM is compared to that of existing techniques in terms of relativity, precision, recall, and time consumption. The performance metrics such as high relativity is about 17-26% are achieved when compared to FiVaTech approach.

Abstract

Background Inflammatory bowel disease (IBD) can lead to substantial impairments of quality-of-life. Clinical guidelines and quality indicators aid physicians in practice but may not reflect the perspectives and experiences of patients with IBD. To address this, the objectives of this study were to understand patient experiences with IBD care and to explore priorities. Methods Based on a convenience sample of 36 participants, five focus groups were completed at four sites across Canada. Data were analyzed using a deductive thematic analysis approach to assess emergent themes and variability in participants’ experiences. Results Our results are organized by themes of structure, process and outcomes to illustrate common issues with respect to how care is organized in the healthcare system, how patients receive and experience care and how patients perceive the outcomes of their care. Our results frame a health systems quality approach that signal needed improvements in access to care, the need for innovation with respect to virtual medicine, the potential expansion of multidisciplinary team-based care and the importance of addressing the psychosocial dimensions for patients with IBD and their caregivers in order to better deliver patient-centred care. Conclusions The issues identified have the potential to impact priority areas in the system, IBD care delivery, and how outcomes can be improved by focusing on ‘lived experience’ and patient-centred care. The differing values and perspectives of all those involved in caring for patients with IBD underscore the importance of good communication with patients, caregivers and family members, as well as staying responsive to evolving needs.

Abstract

This case highlights the importance of pursuing nonpharmacologic analgesic modalities in orthopedic surgery to combat the current opioid epidemic. Presented is a patient who underwent an arthroscopic rotator cuff repair and biceps tenodesis operation and through the use of neurostimulation (in the form of auricular electrostimulation), fully recovered from surgery without the usage of any opioid or nonsteroidal anti-inflammatory medications. The patient was fitted with a novel auricular electrostimulation device (DyAnsys Primary Relief) in the immediate postoperative period that provided constant neurostimulation for 10 days, this neurostimulator was the only analgesic modality used in this case, and the patient reported minimal postoperative pain. The utility of this case centers around the lack of postoperative opioid use, presenting the idea that postsurgical orthopedic pain can be managed in a nonpharmacologic capacity, combatting the fields’ ongoing opioid epidemic.
