Published: November 2022

Geological structures in the Bukit Gadang geothermal area have been identified using the geomagnetic method to determine the type of fault. Data was measured using a magnetometer in the area with dimensions of 1200 m × 1200 m consisting of 144 points at 12 tracks, and the spacing between points was 100 m. Magnetic anomaly data performed diurnal and IGRF (International Geomagnetic Reference Field) corrections. Furthermore, reduced to poles and continuous upwards processes were carried out to remove noise and separate local and regional anomalies. The magnetic field anomaly ​​in the study area ranges from -1771.8 nT to 1089.9 nT, dominated by negative values, indicating the presence of heat sources and the influence of demagnetization of subsurface rocks. The 2D modeling results show that two primary rocks dominate the study area; pyroclastic flow units and andesite lava rock, which come from the Jantan and Batino volcanic formations. The caprock rock layer was identified in the upper layer with a depth of 850 meters. The reservoir rock layer with low susceptibility values ​​was below the caprock layer. The 3D modeling results show a normal fault with a depth of 300-800 meters or at the border of the Jantan volcanic formation with the Batino volcanic formation. The fault line leads to the southeast-northwest (N160°E). The faults obtained from the 2D and 3D models are suspected to be the outflow of geothermal fluid from the reservoir rock layer and form a manifestation in the form of a hot spring at Bukik Gadang.

Published: November 2022

The implementation of Case-Based learning in chemistry learning has grown rapidly in the last ten years. To find trends and issues in the application of case-based learning in chemistry learning, a systematic review is needed. This study aims to analyze the types of CBL and forms of CBL cases used in chemistry learning. The research method used is a systematic review of articles published in the Scopus journal obtained from the Scopus database for the last 10 years (2011-2021). Search articles using titles, abstracts, or keywords that meet logical conditions (“Case-Based Learning”) or (“Case Method”) and (“Chemistry”). The population of this study was 200 articles published in the Scopus database and the sample used was 93 articles. The findings showed that the CBL learning model has a learning syntax that includes four (4) stages, namely: Case Orientation (determining the object to be tested), Peer Instructions (choosing cases that are relevant to the object being studied), Case Review (building initial theory and reviewing literature), Evaluation (collecting, organizing data, analyzing data and developing conclusions). The CBL model presents complex cases in the form of factual news related to the essence of the problem context in the form of story descriptions and integrates information sources in the context to solve cases. The percentages of the 93 articles analyzed were 32% PBI, 31% PBL, and 30% PJBL. Thus, it can be concluded that CBL learning is implemented in three (3) learning approaches, namely CBL in Inquiry-Based Learning, CBL in Problem Based Learning, and CBL in Project-Based Learning

Published: November 2022

Non-thermal plasma is one of the new techniques that is being focused on in the medical world, one of which is used for sterilization because non-thermal plasma is known to have a bactericidal effect. Reactive species produced by non-thermal plasma are antimicrobial. One factor affecting plasma species' reactive composition is the gas source used. Therefore, this study aimed to determine the effect of reactive species produced from non-thermal plasma generation of SDBD using different gas sources, namely free air, oxygen, and nitrogen, in treating Escherichia Coli bacteria. The gas flow used is 1 liter/minute. Reactive species produced by plasma were characterized using Optical Emission Spectrometry (OES). SDBD Non-thermal plasma treatment for Escherichia Coli bacteria samples was repeated three times for each treatment, and then the Anova test was performed. The results of this study indicate that bacterial death at the decontamination level depends on the composition of the gas used during treatment. Plasma using an O2 gas source has a more effective inactivation ability, namely 6 x 107 CFU/ml, compared to the control, which is 409 x 107 CFU/ml. At the same time, the treatment results with free air and nitrogen gas sources were 6.33 x 107 CFU/ml and 41.67 x 107 CFU/ml. These results indicate that the composition of ROS and RNS influences bacterial inactivation, where ROS is more effective in inactivating bacteria than RNS

Published: November 2022

The Bengkaung area, Batulayar District, West Lombok is suspected to be very vulnerable to the risk of earthquake hazards. However, in this area no scientific research, either geological or geophysical, has ever been carried out regarding this hazard. How are the physical characteristics of the lithology and structure in the area to the risk of earthquake disaster? The purpose of this study was to determine the physical characteristics of the lithology and subsurface structures that were validated by the level of damage. The method used is the geoelectric method and local building damage data. The results of the 2D geoelectric anomaly modeling show the characteristics of the subsurface lithological layers in the form of sand, sandstone, clay, andesite lava faults, fresh andesite lava, and granite. The fault was detected in the center of the study area in a north-south direction. Earthquake hazard analysis shows that the cause of the high risk of earthquake hazard in Bengkaung Village is the presence of faults and cohesive lithology. The highest potential risk is in the southern part of Bengkaung Village. The southern area of ​​Bengkaung Village is dominated by clay that has cohesive properties, especially on the surface. The western and northern parts of Bengkaung Village have medium and low vulnerability to earthquake hazards. The last two areas are dominated by non-cohesive soils in the form of sandy soils and lapilli pumice

Multiple treatment options are available for replacement of a missing anterior tooth, each with its own pros and cons. This case report aims to describe the use of a conservative and cost-effective approach for replacing a missing mandibular anterior tooth with periodontally compromised abutment teeth. Here we describe a case in which a single abutment tooth was minimally prepared for a Cantilevered Metal Resin-Bonded Fixed Partial Denture. This report provides a brief literature review regarding the success rates and various designs for resin-bonded fixed prosthesis. It also emphasizes on proper case selection for better long-term prognosis. The results after 1 year follow up of this case demonstrated optimal clinical success of the restoration which encourage the use of this minimally invasive technique for replacing missing teeth.
Urban Development and Fishing Livelihoods in the Museum: Nostalgia and Discontent in Central Vietnam
Authors: Were Graeme
Published: November 2022

This article explores how the topics of fishing and urban development are addressed in a Vietnamese social history museum. Drawing on a project taking place in the Museum of Danang, it describes the way the museum represented the voices of a displaced fishing community who were moved from traditional fishing huts on the riverside to a social housing complex as part of Danang’s urban development plan in the 2000s. Capturing the impact of the community’s relocation on their fishing livelihoods through an exhibition of objects, photographs and texts, the article reveals ways in which nostalgia is recruited to make social, political and moral commentary on urban equality and livelihood change in a rapidly developing city. Methodologically, the project explored the limits of critical representation in an authoritarian state and how nostalgia can be understood as a subtle call for ethical action.

Authors: Simonsson Märit
Published: November 2022

This article examines authenticity in relation to exhibitions about films and television series and the objects they contain, defined here as fiction exhibitions and fiction objects. The study is based on an analysis of Game of Thrones: The Touring Exhibition. Material and constructed authenticity are examined and used in the analysis. It is concluded that the exhibition relates to both categories of authenticity, as it contains authentic material from the production of the series and constructs authenticity by emphasizing the fiction objects’ value. The value of objects is also discussed in relation to the representation of different fictional cultures in the exhibition. Comparing exhibitions and objects of fiction with exhibitions and objects of cultural history, the paper concludes that their authentic qualities are similar, confirming that fiction exhibitions and objects are no less authentic than exhibitions and objects in established museums.

Published: November 2022

Objective: We aimed to compare the distances of the landmarks to the skin, image quality, and ease of application in the ultrasound-guided obturator nerve block (ONB) in different positions.

Materials and Methods: 40 volunteers aged between 20-65 years were included in the study. The distances of the landmarks (anterior and posterior branches of the obturator nerve; junction of the abductor longus and abductor brevis muscles with the pectineus muscle) to the skin, which were taken as a reference for the ultrasound-guided obturator block, were measured and compared in 3 different positions (P1=Neutral position; P2=45o Abduction; and P3=Flexed knee) given to the leg. We also evaluated the quality of the ultrasound image and the ease of application in each measurement by assigning a subjective observer score and comparisons were made for three positions.

Results: While the mean of the distances of the landmarks to the skin were the shortest in P3 and the longest in P1 position, there was no significant difference between the groups (p>0.05). A statistically significant difference was observed between P1 and P3 in the distance of the junction of the muscles to the skin surface (p<0.05). The highest score for the clarity of ultrasound images and ease of accessing the measurement points was the P3 position (p=0.00). In addition, in our correlation analysis, we found that as the distance of the landmarks to the skin surface decreased, the image clarity and the ease of access to the obturator nerve (score) increased, where p<0.05.

Conclusions: In ultrasound guided ONB, in P3 position landmarks get closer to the skin, and image clarity and ease of detection for landmarks increases in parallel with this position. As a result, the ultrasound guided ONB can be best done by giving flexed knee position.

Energy, exergy and cost analysis of flour production from wheat in Nigeria: Case study of Nigeria Eagle Flour mills, Ibadan
Authors: Moradeyo Odunfa  , Olorunferanmi Lois Joel
Published: November 2022

The significant increase in energy costs has generally contributed to an increase in the cost of production, flour production inclusive. In manufacturing industries, efforts are being made towards the reduction of the cost of energy consumed during production. This study was therefore designed to evaluate the energy requirements, operation costs, exergy losses, and propose methods for optimizing energy use in wheat flour production, using Nigeria Eagle Flour Mill, Ibadan as a case study. Analysis was carried out in three phases, pre-analysis, data collection and detailed analysis phases. A walk-through process analysis method was used for data collection and a model containing the mass, energy, and exergy balance equations were built in Microsoft Excel® 2010 to analyse data collected. Electrical energy was found to be the most used energy in both mills and the milling process was the most energy intensive in flour production, accounting for an average energy intensity of 187.49MJ/ton in Mill A and 280.37MJ/ton in Mill B. Lighting was observed to consume approximately 7% of the electrical energy supplied, prompting a lighting analysis to highlight potential energy savings. The energy cost per ton was found to be the lowest (4404naira/ton) when electrical energy from the gas plant accounted for 77 per-cent of energy input. The mill's overall irreversibility and exergetic efficiency were calculated to be 404.942KW and 15.74 percent, respectively. Only 16% of the total exergy input into the flour mill exited through product streams, 1% through waste streams, and 83% was destroyed due to irreversibilities. The B1/B2 rolling bench destroyed the most exergy, accounting for approximately 8.53 percent of the mill's irreversibility. It was established that the components with the highest waste streams had the highest irreversibilities. Minimizing waste streams would reduce the amount of exergy lost and increase the exergetic efficiency of components. To improve system efficiency, several process optimization and machine modifications were recommended.

Background and aim: Obesity and hypertension are public health concerns. An increase in body weight is typically followed by an increase in blood pressure. This study aimed to investigate the association of general and central obesity with hypertension in Bangladeshi adults using WHO classification. Methods: A Cross-sectional study of Bangladeshi adults (both males and females) aged (20-65 years). General obesity was determined by BMI in kg/m2. WHO classification for BMI for Asian population are underweight (BMI <18.5), normal (BMI 18.5-23.5), overweight (BMI 23.5-27.5) and obese (BMI ˃27.5). Central obesity was defined as a WC≥80 cm for females and ≥90 cm for males. Hypertension was defined by systolic blood pressure (SBP) ≥140mmHg and/or, diastolic blood pressure (DBP) ≥90mmHg and/ or, intake of anti-hypertensive drugs at the time of data collection. Prehypertension was defined as SBP 120–139mmHg; and/or DBP 80–89mmHg. Multinomial logistic regression analyses were performed to assess the association of general and central obesity with hypertension. Results: In this study, the overall prevalence of hypertension in Bangladeshi males and females was 15.3% and 6.0% respectively. The males had a higher prevalence of general obesity (13.3%), central obesity (35.3%) and hypertension (15.3%) compared to the females (13.0, 28.5, and 6.0%, respectively). The odds of having hypertension for general and central obesity were 2.18 95% CI (1.12-4.23), 1.53 95% CI (0.94-2.5) while adjusted odds ratio (aOR) were 1.31 95% CI (0.76-2.27) and 1.67 95% CI 0.97-2.87 respectively. Conclusion: Thus, not only general obesity but also central obesity should be used to assess obesity in Bangladeshi adults.

Published: November 2022

The convolutional neural network (CNN) is the most widely used machine learning technique within the fields of image and video processing. It is primarily used to categorize images using vast datasets. This require a lot of calculations. The effectiveness of a field-programmable gate array (FPGA) as a hardware accelerator for CNNs will give excellent performance at low power budgets. The employment of the Winograd algorithm can reduce the number of processing stages in CNN. 2-D convolution is employed for the bulk of calculations in CNNs. The tactic for computing convolution for smaller filter sizes that uses Winograd minimum filtering is the handiest. The comparison of computation complexity for multiplications will be performed using Matlab. The architecture of the Winograd-based processing element, RTL coding in Verilog HDL, and the test bench are designed to examine the performance. The Xilinx Vivado / Cadence tool will be used to implement the processing element in the convolution unit on an FPGA or ASIC.

Yumuşak güç, ekonomik ve askeri gücü öncelikleyen sert gücün yanında politik gücü kullanmanın dolaylı bir yolu olarak tanımlanmakta ve muhatap olunan aktörlerin ve toplumların tutumlarını ve tercihlerini etkileme çabalarını ifade etmektedir. Bu kapsamda bir yumuşak güç bileşeni olarak kamu diplomasisi, maddi olmayan manevi unsurlar marifetiyle muhatap olunan aktör ve toplumların tercihlerinin etkilenmesi şeklinde kavramsallaştırılmaktadır. Dolayısıyla kamu diplomasisi ekonomik ve askeri teşviklere ve tehditlere dayalı güç kullanımının aksine, maddi olmayan varlıklarla yakından bağlantılıdır. Kamu diplomasisi temelde bir ülkenin politikalarının ve toplumunun bir başka ülke yönetimi ve halkı tarafından hoş görülmesi ve desteklenmesi maksadıyla, ülkenin belirli politikalarının anlatılması ve muhatapların ikna edilmesi, ülkenin kaynaklarının tanıtımının yapılması için, sivil toplum kuruluşları veya gerçek kişiler gibi devlet dışı kurumlar tarafından gerçekleştirilen çabaların tümüdür. Bu çalışmada kamu diplomasisi olgusu çeşitli boyutlaruyla açıklanmakta, akabinde önemli bir kamu diplomasisi vasıtası olarak diaspora ve Avusturya Türk diasporası üzerinden ve Avusturya Türkiye minasebetleri bağlamında bir değerlendirme yapılmaktadır. Bu bağlamda başarılı birer kurumsallaşmış kamu diplomasisi vasıtaları olarak Yunus Emre Enstitüsü ile Avusturya Türk Kültür Vakfı üzerinden kavramsal bir inceleme yapılmaktadır.

One of the good sources of animal protein comes from meat because it contains various kinds of nutrients needed by the body including protein, carbohydrates, water, vitamins, fats and various essential amino acids. The presence of high nutritional value in meat can also be utilized by various microorganisms to grow so that it can reduce the quality of meat. Some of these microorganisms can be transmitted to humans and cause disease or also known as zoonotic diseases. One way to prevent the growth of microorganisms in meat is by preserving meat using natural ingredients that can come from plants. One of the plants that has the potential to inhibit bacterial growth is Salam leaves (Eugenia polyantha, Weight.). The purpose of this study was to determine the value of the content in Salam Leaves (Eugenia polyantha, Weight.) and to determine the effect of giving Salam Leaf extract (Eugenia polyantha, Weight.) to early decay, pH value and Total Bacterial Colony. The study began with the collection of Salam leaves (Eugenia polyantha, Weight.) and then the extract was made. The extract obtained was then diluted and stored. The research was continued by taking meat samples from the Traditional Market in Surabaya and then cut into uniform sizes and soaked in Salam leaf extract with different concentrations. After incubation, the meat quality was tested for the beginning of spoilage, pH value and total bacterial colonies. The results of the observations showed that the best results were found in the P4 treatment with an extract concentration of 20%. This result is indicated by the lack of fog formed in the initial spoilage test, the pH value is close to the ultimate pH of the meat and a low total bacterial colony.

Floor cleaning and disinfection are essential components of maintaining animal health status and meeting regulatory requirements in research vivaria. However, best practices for method, frequency, and evaluation techniques have not been established. Reuse of cotton string mop and bucket
systems has been implicated in spreading contamination in the human hospital setting. We evaluated 4 different combinations of disinfectant and mop systems commonly used in rodent vivaria. Eight housing rooms were mopped a total of 4 times using one of the following methods: quaternary ammonium
compound (QUAT) and cotton string mop (QC), QUAT and microfiber mop (QM), hydrogen peroxide disinfectant (HPD) and cotton string mop (HC), or HPD and microfiber mop (HM). ATP and RODAC samples of the floor were taken before and after mopping. The time to mop each room, floor drying time, and
the amount of disinfectant used were recorded. The QC method was associated with significantly more bacterial contamination while all other methods significantly reduced bacterial contamination. The QC method performed significantly worse in reducing bacterial contamination as compared with
all other methods when cotton mop heads were reused. All methods except QC significantly reduced ATP levels, with the HC and HM methods being significantly more effective at reducing ATP levels than the QC and QM methods. Costs were similar for the QC, QM, and HM methods. The results of this
study indicate that reuse of cotton string mop heads with QUAT increases floor contamination while HPD is effective for up to 3 reuses. Single use microfiber mops were effective with both QUAT and HPD but did not result in more effective cleaning or disinfection than cotton string mops.
