Authors: Rao K. Tejeswara , Rao D. Uma Maheswara , Kumar P. B. Pradeep
Published: August 2022

In agriculture, green manure is created by leaving uprooted or sown crop parts to wither on a field so that they serve as a mulch and soil amendment. The plants used for green manure are often cover crops grown primarily for this purpose. The green manuring is the easiest and cheapest way to enrich the soil fertility besides adding huge amount of organic carbon to the soil and also which prevents soil erosion. The non-availability of green manure seed preceding to paddy is major a constrain at farmers level. In rice fallow pulses the yields are declining due to severe incidence of YMV and farmers are unable reap the pulses in rice fallow situations. Keeping in view of the present scenario in rice fallow pulses, this study on performance of seed production of green manure crops for seed availability and profitability were taken up in farmers fields as On Farm Testing. In the present study the performance of, sunnhemp (Crotalaria juncea L.) was studied for seed yield in rice fallow situation during Rabi, 2018-19 and Rabi, 2019-20 under rainfed ecosystem by DAATT Centre in collaboration with Department of Agriculture.The On-Farm Trails (OFTs) were conducted at farmers fields in 7 locations randomly covering entire district in Rabi, 2018-19 and Rabi, 2019-20. Observations were recorded on days to maturity and seed yield. The results revealed that significantly higher seed yield was observed in sunnhemp. Seed yield increase was achieved to a tune of 84.00% in sunhemp crop (1179 kgha-1) over control. The increase in seed yield could be attributed to the performance of sunnhemp crop in-terms of more growth and yield components. The farmers realized that, sunnhemp is best suitable green manure crop for seed production in Visakhapatnam district of North Coastal Zone, Andhra Pradesh.

Authors: BULUT Murat , SÖZBİR Nedim
Published: August 2022

Battery technology has been used for geostationary satellites since the first satellite sputnik-1 was launched in 1957. The majority of larger geostationary satellite’s lives range from 7 to 15 years. During the lifetime of satellites, the batteries used must complete 1000 to 33000 cycles without any problems or likelihood of maintenance. There are three battery technologies, Li-ion, Ni-H2 and Ni-Cd, that are well proven for Geostationary satellite applications. Energy density, lifetime, weight, ampere-hour capacity, depth of discharge, ruggedness and recharge-ability, battery management, thermal management, and self-discharge are main parameters that should be considered when comparing electrical and thermal performance of these three battery technologies. The purpose of this study is to compare the thermal control system for these three batteries for three-axis stabilized geostationary satellites. In particular, the thermal dissipation was compared, which is the temperature range required for battery operation. Thermal analysis was performed for Li-ion batteries using ThermXL software, and showed a temperature results variation ranging between 10.9 oC and 32.7 oC. The temperature during the battery module was not greater that its qualification temperature results.
Neutronic and Thermalhydraulic Evaluation of Annular Fuel in PWR with Three Different Nanofluids
Authors: TİFTİKÇİ Ali
Published: August 2022

In pressurized nuclear reactors, one of the fuel design principles is the fuel centerline temperature limit. Since the thermal conductivity of UO2 is not high, the temperature increases rapidly from the fuel surface to the fuel center. To overcome this limitation, the use of annular type fuels instead of solid fuels is one of the improvement efforts. In this study, the effects of using annular fuel in a typical PWR are investigated. At the same time, the effects of adding nanoparticles (〖Al〗_2 O_3,Cu and TiO_2) to the coolant water in the case of solid and annular fuels are also investigated. For both cases, neutronic and thermalhydraulic calculations are made and compared. In neutronic point of view, it has been shown that the use of annular fuel does not cause a significant change in the k_eff value but the presence nanoparticles reduces the k_eff. This reduction is maximum for Cu+water and minimum for 〖Al〗_2 O_3+water nanofluids. In thermalhydraulic point of view, it has been shown that the annular fuel positively affects the fuel temperature limits and the addition of nanoparticles could provide an additional contribution to this, provided that it is in very small amounts (φ

Authors: Gradidge Philippe , Phaswana Merling , Chau Josephine
Published: August 2022

Background: Data from empirical investigations on the feasibility and acceptability of using sit-stand desks in an office-based setting in low- and middle-income settings are limited.
Objectives: To explore the perceptions of South African office workers towards using height-adjustable sit-stand desks to reduce sitting time during vocational hours.
Methods: Self-reported sedentary behaviour and in-depth, semi-structured interviews were conducted in December 2020. Thematic content analysis approach was used to develop themes.
Results: Eleven office workers with a work-time sitting time of 8 (6-8) hours were interviewed (age 40.5 ± 12.6 years), most (91%) were female. The main themes emerged and included: overall impressions of the height-adjustable sit-stand desks; enablers versus barriers to using the desk and readiness to continue using sit-stand desks.
Conclusion: The findings of this research add to the evidence on environmental workstation modifications for reducing sedentary behaviour. Further investigations on the efficacy of sit-stand desks are recommended in South African university office workers.

Published: August 2022

The research was conducted to study physical parameters and histological structural patterns based on the coat color of Black Bengal goat skins. Five hundred skins were randomly selected, and measured using scientific instruments and the Haematoxylin-Eosin staining method was used for histological study. Black coat color skin was found the highest (58%), the mean weight, length, and width of Black Bengal goat skin was 998.80 gm, 29.24, and 20.91 cm, respectively but there were no significant differences among the groups. The mean thickness of the skin was 1.97, 1.43, and 1.96 mm in the butt, bell, and shoulder regions, respectively, and significantly different between the groups in all categories. All slaughtered goats were flayed using the “Muchki” (Hoisting and fisting) method. The average flay cut length, depth, and mechanical and parasitic damages were 20.2 mm, 1.50 mm, 6.11, and 1.50 %, respectively. No significant difference (p > 0.05) was found in inedible fleshing by-products, but significant differences (p < 0.05) were found in trimming by-products production and salt required for curing. Salted skins were preserved for an average of 3.5 days. Hair follicles, sebaceous glands, erector pili muscles, collagen fibers, and fiber bundles were more regular in the butt region than shoulder and belly regions in the black, brown, white, and mixed coat color of Black Bengal goat skins.

How Citizenship Norms and Digital Media Use Affect Political Participation: A Two-Wave Panel Analysis
Authors: Oser Jennifer
Published: August 2022

A centrally important question for researchers of media and communication is whether any type of individual-level behavior (e.g., digital media use) or normative attitude (e.g., norms of good citizenship) contributes to equalizing patterns of political participation, which often favor higher-status groups. Drawing on a two-wave repeated panel telephone survey that uses a nationally representative sampling frame, the study’s research design facilitates a robust analysis of how citizenship norms and digital media use affect political participation, with a focus on comparing higher- and lower-status groups. Specifically, the study analyzes a survey conducted in 2018 (Wave 1) and 2019 (Wave 2) among Israeli citizens, with a representative sampling of the generally higher-status Jewish majority and the lower-status Arab minority. The findings indicate that citizenship norms and digital media use in Wave 1 have a time-ordered positive effect on nonelectoral participation in Wave 2 for both Jewish and Arab citizens of Israel. However, the findings also show that for voting, the only statistically significant determinant is citizens’ Jewish or Arab identity. At a time when many democracies are facing severe challenges due to democratic erosion and social disintegration, this study contributes a normatively encouraging finding that key factors identified in the literature on citizenship norms and digital media use do not contribute to participatory inequalities between the Jewish majority and Arab minority in Israel. The findings also show, however, that it is essential to look beyond digital media use patterns to mobilize lower-status groups to become politically engaged in electoral-oriented politics.

Published: August 2022

The paper examined the disaster awareness and preparedness in Nigerian polytechnic libraries. A survey research design was used for the study. Purposive sampling was used to select one hundred and forty respondents from the library staff which include the academic staff and the non-academic staff. Questionnaire was used as the main instrument for gathering data. Findings revealed that that there is no disaster control plans in the polytechnic libraries under the study and the staff admitted that they were not preparing for disasters. Fire extinguishers were the common disaster equipment available in all the libraries. Lack of fund and disaster control plans were the major constraints facing the staff in creating awareness and preparing for disasters. The paper recommended that polytechnic managements should constitute disasters control committee in all the polytechnic libraries and at the same time disaster control plans should be made compulsory in all the polytechnic libraries as part of their working document.

Published: August 2022

A capacidade do algodoeiro de se recuperar após uma desfolha se faz em função do nível de redução da área foliar, estágio de desenvolvimento da planta em que ocorrer a injúria, condições climáticas e práticas do sistema de cultivo. O objetivo deste estudo foi avaliar os efeitos da desfolha no desenvolvimento, produtividade e qualidade de fibra do algodoeiro, nos sistemas de espaçamentos adensado e convencional. Para isso, conduziu-se experimentos em condições de campo, em Dourados (MS), utilizando-se a cultivar NuOpal RR®, em delineamento de blocos ao acaso (com parcelas subdivididas) e quatro repetições em dois sistemas de cultivo (adensado e convencional). Os tratamentos constituíram-se de cinco fases de desenvolvimento da cultura: V3, B1, F1, F5 e C1, (de acordo com a escala de Marur e Ruano (2001) e quatro níveis de desfolhamento artificial (0%, 33%, 66% e 99% da área foliar). O efeito da desfolha nos índices de produtividade e qualidade de fibras foi dependente do estádio do fenológico em que a cultura se encontrava independente do sistema de cultivo estudado. Já quando as plantas estavam nos estádios B1 e F1 e sofreram desfolha de 99%, este afetou os índices de qualidade de fibras, enquanto a redução de área foliar no estádio C1 não afetou os índices de qualidade e produtividade do algodoeiro.

Abstract
The ability of the cotton plant to recover after defoliation is a function of the level of reduction of the leaf area, stage of development of the plant in which injury occurs, climatic conditions and practices of the cultivation system. The objective of this study was to evaluate the behavior of cotton submitted to different levels and times of defoliation in systems of conventional and narrow row cultivation. Experiments were conducted in field conditions, in Dourados (MS), using the cultivar NuOpal RR® in a randomized block design (with subdivided plots) and four replications in two cultivation systems (narrow row and conventional). The treatments consisted of five stages of crop development: V3, B1, F1, F5 and C1, (according to the scale of Marur & Ruano (2001) and four levels of artificial defoliation (0%, 33%, 66 % and 99% of the leaf area artificially eliminated.) The effect of defoliation on the indexes productivity and fiber quality depends on the phenological stage in which the culture was, independent of the cultivation system studied. When the plants were in stages B1 and F1 and suffered defoliation of 99%, this affected the fiber quality indexes, while the reduction of leaf area in the C1 stage did not affect the quality and productivity indexes of the cotton.

Published: August 2022

Bezoars are concretions of undigested or partially digested foreign material in the gastrointestinal tract. They occur in patients with altered gastrointestinal motility or anatomy (previous gastricsurgery, diabetes mellitus, neurological disorders). They are rare, with an estimated %0.3 on upper endoscopy. The most common symptoms include abdominal pain, nausea, vomiting, early satiety, anorexia, and weight loss. We present a patient who diagnosed with 8-9 cm phytobezoar, and treated by endoscopic method. An 87 years old woman presented to our emergency room with upper abdominal pain, nausea, and postprandial emesis for 3 days. Emergency esophagogastroduodenoscopy revealed prepyloric antrum, gastric phytobezoar (8-9 cm) and ulcers (10-12 mm). We used an endoscopic snare to cut the bezoar into several pieces. After endoscopy, all bezoars disappeared. There was no recurrence during 1-year follow-up. In conclusion, endoscopic treatment may be a safe and viable option for the extraction of gastric bezoars presenting with gastric outlet obstruction. This is the rare case that such a large phytobezoar (8×9 cm) has been fragmented with an ordinary polypectomy snare.

The objective of this present study is to signify biochemical features of three reared trouts (brook trout, rainbow trout, Black Sea trout) that are economically consequential and reared fish species in the Eastern Black Sea region. The rainbow trout has been reared successfully for a long period of time. However, brook trout and the Black Sea trout have been two new species to be reared in the region with a high potential contribution to the economy. Therefore, there is a strong need to determine and report the differences between the fish (especially the two new species), levels of carbohydrates, energy, carotenes (Vitamin A), fatty acid, and proximate composition (protein, lipid, moisture, and ash). In addition, the lipid indices [Atherogenic Index (AI), Thrombogenic Index (TI), and polyene index (PI)] were also measured and reported for the trouts. Moreover, the color of the fillets of the fish was also measured. The results of this present study show that the average levels of moisture and protein varied while the average levels of lipid and ash were close to each other. The highest levels of carbohydrates, energy, and carotenes were determined in the muscle of brook trout in this study. The highest meat yield was also obtained from brook trout followed by Black Sea trout and rainbow trout. A total of 19 fatty acids were determined for Black Sea trout and brook trout and 17 fatty acids for rainbow trout in the present study. The omega-3 levels of the all trout used for the present study were roughly twice as much as that of the omega-6, except for rainbow trout.

For this purpose, a face-to-face survey was conducted with 325 randomly selected enterprise owners. It was determined that 94.7% of the barns in the enterprises in the county consisted of tied free-stall barns. Furthermore, 33% of the barns were between 16 and 20 years old and 31.2% of them were older than 21 years. Stone (95.4%) and brick (66.2%) were commonly used as building materials in the construction of the barn walls, and mainly galvanized sheet metal (77.4%) was used for the roof. The barn floor was also determined to be mostly concrete (61.9%) or stone (48.2%). Some of the standard barn elements were available in almost all of the enterprises in the county, such as feeder (100.0%), urinary canal (85.3%), window (96.7%), however other elements such as the feeding alley (6.6%), automatic waterer (1.3%) and ventilation holes (22.8%) were available in a small number of enterprises. The relationship between the number of windows in the barns, the level of farm size and the level of education of the breeders was found to be statistically significant (P<0.01). The percentage of enterprises with two windows in their barns was the highest (48.2%) in the county, and this was followed by enterprises with three, four, one and five windows in the barn, respectively.

C. cyminum (cumin) and M. communis (myrtle) comprise many biologically active molecules. In this study, cumin seed and myrtle leaves were mixed then hydrodistilled and analyzed by GC-MS. The main components of the essential oil were cuminal (50.71%), 1,8 cineole (8.30%), O-cymene (7.88%), β-pinene (7.62%), α-pinene (7.16%), γ-terpinene (6.09%) and α-terpinolene (2.19%). The antifungal activity of the essential oil against C. albicans, C. parapsilosis and C. tropicalis was investigated using spectrophotometric broth microdilution, colorimetric broth microdilution, and agar well diffusion tests. Antimicrobial mechanism of the EO was researched by TTC-dehydrogenase relative activity, protein and DNA leakage analysis. While the MIC values of the oil were 3.29 mg mL-1 for C. albicans, 3.57 mg mL-1 for C. parapsilosis and 3.65 mg mL-1 for C. tropicalis, the 50% cytotoxic concentration values were between 0.17 mg mL-1 and 2.61 mg mL-1 for Candida species. The inhibition values against yeasts in dark and light conditions were found as 42.1 mm on C. parapsilosis and 39 mm on C. tropicalis exposed dark and light, respectively. The inhibition zones of oil in water, glucose, glycerol and salt environment. As a result, the highest IZ was found as 26.6 mm on C. albicans and 26 mm on C. tropicalis in the presence of a 3% glycerol environment. The DNA and protein levels were increased when yeast was exposed to the EO. As a result, the oil of mixed C. cyminum and M. communis preserved its antimicrobial stability in different environmental conditions and should contribute to new antifungal research.

The efficiency of Islamic banking practices operating under the name of Participation Banks in Turkey and their share in the financial system have gradually increased, and thanks to the products offered by these banks, significant progress has been made in bringing savings into the financial system, in obtaining resources from abroad as well as from within the country, and in the diversification of resources. Determining the impact level of global crises to the Islamic banking system, which is built on interest-free transactions, will enable the efficiency of the system to be determined and the necessary improvements to be made for the faulty aspects. In this context, in our study, the developments in the performance of participation banks operating in Turkey in the face of global economic/financial problems caused by the 2008 global financial crisis and the Covid-19 pandemic are discussed in comparison with deposit banks. By using the Gregory-Hansen cointegration test, which considers the structural breaks in the system, the effects of the ratio of operating expenses to assets, financing-deposit (participation fund) ratio, non-performing financing ratio, and capital adequacy ratio indicators on the return on assets were analyzed. According to the findings, there was a break in the performance of participation banks in 2010 (the period when the crisis turned into a debt crisis in Europe) after the 2008 global financial crisis, but no break in the pandemic process. In terms of deposit banks, a break occurred in 2009, right after the global financial crisis. Other findings of the study include that the Covid-19 process did not create a break on deposit banks.
PETROL FİYATI ŞOKLARININ BİST100 GETİRİ ENDEKSİ ÜZERİNE KISA VE UZUN DÖNEM ASİMETRİK ETKİSİ: NARDL YAKLAŞIMINDAN KANITLAR
Authors: ALTINTAŞ Halil
Published: August 2022

Bu çalışma, Türkiye’de 2003 Ocak-2019 Ocak dönemi arasında Ready (2018) tarafından önerilen üç farklı petrol fiyatı şokunun (talep, arz ve risk) BIST100 getirisi üzerindeki doğrusal olmayan etkisini NARDL modeli yaklaşımı ile incelemektedir. Elde ettiğimiz sonuçlarda petrol fiyatı şoklarıyla BIST100 getirisi arasında doğrusal olmayan eşbütünleşme ilişkisinin varlığına ve petrol fiyatı şoklarındaki pozitif ve negatif değişmelerin kısa ve uzun dönemde önemli ölçüde değiştiği sonucuna rastlanmıştır. Pozitif ve negatif petrol talep şokları katsayıları sırasıyla, pozitif ve negatiftir ve pozitif petrol talep şokunun negatif petrol talep şokundan daha büyük ekonomik etkiye sahiptir. Bu sonuç global talep artışından hisse getirilerinin daha fazla etkilendiği anlamına gelmektedir. Toplam etkiler değerlendirildiğinde hem pozitif petrol arz şokunun hem de pozitif petrol talep risk şokunun incelenen dönemde hisse senedi getirilerinin azalmasında daha büyük etkiye sahip olduğu sonucuna ulaşılmıştır.

Çalışmada, Ankara ili Çankaya ilçesinde mesken nitelikli bağımsız bölümlerin fiyat oluşumunda etkin olan parametreler mekânsal ekonometrik yöntemlerde En Küçük Kareler (EKK) yöntemi kullanılarak Spatial Error Model (SEM), Spatial Auto Regressive Model (SAR) ile Spatial Durbin Model (SDM) tarafından döndürülen sonuçlara göre değerlendirilmiştir. Belediyelerin en önemli gelir girdisi olarak emlak vergisinin doğru belirlenmesi bağımsız bölümün fiyatının olabildiğince doğru tahmin edilebilmesine fiyatın doğru tahmin edilebilmesi ise fiyatı oluşturan parametrelerin doğru belirlenebilmesine bağlıdır. Mekânsal ekonometrinin sonuç çıktılarından olan rho katsayısı ile belirlenen yapı stoklarının birbirlerinin fiyatına olan etkisi aracılığıyla incelenen birimdeki sosyal etkileşim de belirli bölgelerin oluşturulması esnasında göz önüne alınması gereklidir. Durbin modelinin döndürdüğü çevre etkileşimi ise hangi sosyal tabakaların hangi fiyat oluşumuna ne kadar etkin olduğunun belirlenmesinde bir araç olarak kullanılabilir. Mekânsal ekonometrik sonuçların doğru değerlendirilmesi fiyat oluşumundan sosyal tabakaların etkileşimine kadar birçok konuda karar verilebilmesine yardımcı olabilecektir. Çalışmada emlak beyan değeri üzerinde etkin parametrelerin özellikle beyan değerinin denklemden dışlanmasıyla ortaya çıktığını dolayısıyla beyan değerinin doğru olarak belirlenmesinin ne derece önemli olduğu ortaya konulmuştur. Bu bağlamda belediyelerin profesyonel kurumlardan destek alması zorunluluğu da çalışmanın gayri ihtiyari sonuçlarından birisi olarak ortaya çıkmıştır.

Since the beginning of the pandemic, COVID-19 (COronaVIrus Disease-2019) has been viewed as a respiratory disease with characteristic symptoms including cough, shortness of breath, and difficulty breathing. However, some patients still have respiratory complaints and post-inflammatory changes in the lung tissue according to high-resolution computed tomography of the chest organs (CT scan) even after discharge from the hospital.

The aim. To assess the functional changes in the respiratory system in patients who had COVID-19-associated lung injury using a comprehensive testing of the respiratory function (spirometry, body plethysmography and diffusion test) in the first 6 months after discharge from the hospital.

Methods. The study included 434 patients (252 men and 182 women, aged 20 to 79 years), who were divided into 3 groups depending on the time interval between discharge from the hospital and the respiratory function test: Group 1 – 15 – 45 days; Group 2 – 46 – 93 days; Group 3 – 94 – 183 days. All patients underwent a comprehensive testing of respiratory function.

Results. The average pulmonary ventilation indicators remained within the normal range both in the general group and in separate groups. A decrease in DLCO was found in most patients: in 53% of people in the general group, in 54, 54 and 51% of cases in Groups 1, 2 and 3, respectively. Restrictive ventilation disorders (reduction of TLC below the lower limit of normal (LLN)) were detected in 29 % of people in the general group, 33, 27 and 26% in Groups 1, 2 and 3, respectively. Obstructive ventilation disorders (decrease in FEV1/FVC below LLN) were detected in 2 % in the general group, and in 3, 1 and 1% in groups 1, 2 and 3, respectively. Statistically significant correlations were found between the maximum volume of lung tissue damage in the acute period of COVID-19, the age of the patients, and the respiratory function indicators.

Conclusion. The pulmonary ventilation indicators normalized within 6 months after COVID-19, while a decrease in lung diffusion capacity persisted in most patients and required further active follow-up.

Computed tomography (CT) guided percutaneous procedures like the fine needle aspiration cytology (FNAC) and fine needle aspiration biopsy (FNAB) are reliable techniques for diagnosing various thoracic diseases. These modalities are used for diagnosis in suspicious lung, pleural, mediastinal and vertebral and pulmonary lesions.

The aim. We conducted a study in a Pulmonary Medicine Department of tertiary care hospital to study the efficacy and safety of CT guided FNCA/FNAB in thoracic diseases.

Methods. A retrospective study was conducted at a tertiary care center with Information and Ethics committee permission within a total duration of two years. The study included patients presenting with following: 1) mediastinal mass lesions, 2) pulmonary solitary pulmonary nodules/masses, 3) pulmonary cavity, cyst and consolidation of undiagnosed etiology, 4) pleural mass, nodules, loculated collections, 5) extra-pulmonary and spinal tuberculosis suspects with pre/paravertebral abscess. Procedure details, radiological images and pathological and microbiological reports were retrieved from case record book of patients available in department.

Results. Study population consisted of 108 patients. Neoplastic diseases were 85 (78.70%) and Non- neoplastic diseases 23 (21.29%). In neoplastic diseases 78.82% patients had lung Cancer of which 85.07% non small cell carcinoma and 14.92% small cell lung cancer. Out of non small cell lung cancer adenocarcinoma of lung was the commonest. The most common non neoplastic diseases was tuberculosis. CT guided biopsy procedure was performed without any complications in 61.11%. The most common complication was pneumothorax (27.77%). The yield of CT guided biopsy was 98.14%.

Conclusion. Percutaneous CT-guided lung biopsy is an effective, highly accurate, and safe method of obtaining tissue for the diagnosis of indeterminate pulmonary lesions especially in neoplastic diseases and tuberculosis.
