Authors: Kavka Mariya
Published: October 2023

The aim is to identify and analyze risk factors for venous thromboembolism in patients diagnosed with uncomplicated acute calculous cholecystitis.

Materials and Methods. A prospective analysis of clinical data of 71 patients diagnosed with uncomplicated acute calculous cholecystitis was conducted. Two clinical groups were formed: subgroup 1A (n=6) included patients diagnosed with venous thromboembolism, and subgroup 1B (n=65) included patients without venous thromboembolism.

Results and Discussion. During the study, the coagulation potential of the patients was studied. The prothrombin index on the third day of the postoperative period and at the time of discharge was significantly higher in subgroup 1A patients (109.1% and 123.0%) compared to subgroup 1B patients (98.0% and 96.4%). The situation with total fibrinogen is similar: the mean level of this indicator during the entire observation period was significantly higher in patients of subgroup 1A (p<0.05). The mean D-dimer level at the time of hospital discharge in subgroup 1A was 3.6 mg/ml higher compared to the level of this indicator on the first day after surgery, and in subgroup 1B it was only 0.5 mg/ml higher. The risk of venous thromboembolism according to the Caprini score in subgroup 1A was 7.5 [5.5; 9.0] points, compared to 6.0 [4.0; 8.0] points in subgroup 1B. Assessment of the risk of venous thromboembolism according to the Rogers scale showed similar results: 8.0 [6.3; 9.8] points for patients of subgroup 1A and 7.0 [6.0; 8.0] points for subgroup 1B. When assessing the interleukin 1 beta (IL1b) level, its increased value was detected in subgroup 1A - 14.0 [7.0; 33.7] pg/ml, as opposed to subgroup 1B, where it was 9.0 [3.5; 26.2] pg/ml. Similar results were found in the assessment of tumor necrosis factor TNF: the mean values of this cytokine level were also higher in subgroup 1A (13.9 [7.9; 15.8] pg/ml) than in subgroup 1B (8.8 [6.0; 13.1] pg/ml).

Conclusions. According to the results of the study, the following factors for the development of venous thromboembolism in patients with uncomplicated acute calculous cholecystitis were determined: elevated levels of indicators of total fibrinogen, D-dimer, interleukin 1 beta (IL1b) and tumor necrosis factor (TNF) at the time of admission. The mean values of the total risk assessment points according to the Caprini score and Rogers scale were significantly higher (p<0.05) in the subgroup of patients with uncomplicated acute calculous cholecystitis who later developed venous thromboembolism.

Mesenchymal stem cells (MSCs) are used for the improvement of the repair of allografts.

Aim. Based on the analysis of cytokines and proteins of the extracellular matrix in the blood serum of laboratory rats, to evaluate the course of metabolic processes after filling a defect in the femoral metaphysis with allogeneic bone implants saturated with MSCs.

Material and Methods. On the model of a transcortical defect in the metaphysis of the femur, the content in the blood serum of 3 and 12 months white rats of interleukin-1 (IL-1), interleukin-6 (IL-6), transforming growth factor-b (TGF-b), osteocalcin (OC) and osteopontin (OP) on the 14th, 28th and 90 days was investigated.

Results and Discussion. Use of MSCs in 3-month-old rats led to an increase in IL-1 concentration: 0.300(0.269; 0.329, 0.308(0.273; 0.339), 0.295(0.271; 0.319) pg/ml of IL-1 for the 14th, 28th and 90th days, respectively, which higher than the level of rats without MSCs by 1.69 (p=0.008), 1.37 (p=0.008) and 1.46 (p=0.008) times, respectively. For 12-month-old rats: IL-1 (0.414(0.387;0.437), 0.426(0.389; 0.448) and 0.407(0.368;0.423) pg/ml on the 14th, 28th and 90th days, respectively), which exceeded the data of rats without MSCs in 1.69 (p=0.008); 1.38 (p=0.008) and 1.46 times (p=0.008). In the blood serum of rats with MSCs TGF-b: 3-month: - 1.826(1.637;2.015), 1.379(1.247; 1.568) and 1.675(1.476;1.893) ng/ml on the 14th, 28th and 90th days, respectively, which was 1.57 (p=0.008), 1.98 (p=0.008) and 1.51 (p=0.008) times less than the data of the comparison group; 12-month-old - 1.976(1.749; 2.234), 1.492(1.218;1.734) and 1.813(1.636;2.028) ng/ml on the 14th, 28th and 90th days, respectively, which is less than the level of rats without MSCs of 1.50 ( p=0.008), 1.92 (p=0.008) and 1.51 (p=0.008) times. When introducing MSCs OP: 3-month-old rats - 13.55(12.90; 14.04), 14.14(13.43;14.87) and 14.12(13.75;14.77) ng/ml, which was higher than in rats without MSCs in 1.11 (p=0.008), 1.11 (p=0.008) and 1.17 (p=0.008) times; 12-month-old - 15.26(14.70; 15.81), 16.38(15.88; 16.91) and 16.06(15.53; 16.67) ng/ml, which is more than the comparison group 1.11 (p=0.008), 1.16 (p=0.008) and 1.22 (p=0.008) times;

Conclusions. Saturation of allografts with MSCs led to an increase in biochemical markers of inflammation from the 14th day. Bone remodeling in rats with MSCs was characterized by lower activity. In 12-month-old rats in comparison with 3-month-old animals we noted more active inflammation, with a slowed activity in bone remodeling.

Authors: Sych Susan Margaret
Published: November 2023

The following article provides a historical perspective to the notion there is a divide between academic and vocational education and training (VET). The author explores the biases held by parents, teachers, administrators and policy-makers toward VET, and provides explanations of why these views might be held. Even though positive changes have been made in promoting VET there still remains an undercurrent of negative discourse. The autobiographical approach of the article provides the writer with the means to challenge the negative perspectives, and presents a personal view into how VET might be vindicated from denigrating attitudes.
The Relationship Between The Attitudes of Teaching Profession, Life Satisfaction, Possible Selves and The Emotional States of Pre-Service Teachers

Published: October 2023

In this study, the relationship between pre-service teachers' attitudes towards the teaching profession, their life satisfaction, possible selves and emotional states were examined. This study, in which the quantitative research approach was adopted, was carried out with the relational survey model and was realized with the participation of 685 pre-service teachers. Data were collected in the 2021-2022 Academic Year. Personal information form, “Attitude Scale Towards Teaching Profession”, “Life Satisfaction Scale”, “Pre-service teachers' Possible Self Scale” and “Emotional State Scale” were used as data collection tools. As a result of the analyzes, it was seen that there was a positive and significant relationship between the attitudes of pre-service teachers towards the profession and their life satisfaction, expected possible teacher selves and emotional states. Accordingly, the more the teaching profession is loved and the more it satisfies the teacher, the more it can improve the quality of life in a positive way. In addition, a negative relationship was found between the pre-service teachers' life satisfaction and feared potential teacher selves, and a positive relationship was found between their life satisfaction and emotional states. This result suggests that there is a link between pre-service teachers' overall life satisfaction and their concerns about future teacher roles and responsibilities. Another result of this study is that there is a positive relationship between the pre-service teachers' emotional states and their expected potential teacher selves, and a negative significant relationship between their emotional states and feared possible teacher selves. This result means that pre-service teachers' feared potential teacher self-perceptions may become stronger when they evaluate themselves negatively, have concerns about their professional future, or have negative emotional experiences. According to the results of this study, it is understood that pre-service teachers' attitudes towards the profession are related to both their self-esteem as a teacher and their perception of professionalism.

Published: November 2023

The need for improved wet adhesives has driven research on mussel-inspired materials incorporating dihydroxyphenylalanine (Dopa) and related analogs of the parent catechol, but practical application of these functionalities is limited by their susceptibility to oxidation. Here, we investigate the molecular-level adhesion of the catechol analogs dihydroxybenzamide (DHB) and hydroxypyridinone (HOPO) as a function of pH. We find that the molecular structure of the catechol analogs influences their susceptibility to oxidation in alkaline conditions, with HOPO emerging as a particularly promising candidate for pH-tolerant adhesives for diverse environmental conditions.

Authors: Mwesiga T. R. , Kaswamila A. L. , Mwakipesile A. E.
Published: October 2023

Purpose: The purpose of this study is to investigate the implications of these reforms from a revenue collection perspective in Geita District using Geita Gold Mine Limited (GGML) as a case study.

Design/Methodology/Approach: This study utilizes a mixed-method approach, by using both qualitative and quantitative approaches. The study population consisted of individuals from sampled households in six wards around GGML with a sample size of 384 respondents. The study used both stratified and simple random sampling methods in selecting respondents.  The qualitative data were collected through in-depth interviews, focus group discussion and documentary analysis while the quantitative data were collected through the survey method. Qualitative data were analysed using content analysis and quantitative data from households were analysed using descriptive statistics.

Research Implications/Limitations: This study is limited to GGML and Geita District only, which may not fully capture the diverse range of other mining companies operating outside the district within Tanzania.

Findings: Study findings indicated that the mining legislation helped to improve the quality of institutions as well as resource governance. For instance, due to improvements in resource governance such as the increase in royalty and mining supervision the revenue from mining activities almost tripled to a total of TZS 664 billion as compared to TZS 196 billion that was collected four years back from 2017.

Practical Implications: The findings are expected to have a significant on improving the traceability of gold production and reporting their activities more transparently. Additionally, reforms can lead to more efficient and effective collection of royalties, taxes, and fees related to gold mining operations, resulting in increased government revenue

Social Implications: The social implications of this research are essential, as the increase in mining revenue through taxes, royalties, service levies and other fees can help to improve social services such as education and health services. The mining sector can also contribute to the provision of employment to host communities which has a direct impact on improving social welfare.

Originality/Value: The novelty of this research lies in its holistic and sector-specific examination of revenue collection reforms in the gold mining industry, considering economic, environmental, social, and governance dimensions. It offers a comprehensive understanding of how reforms in this critical sector can impact both individual nations and the global resource landscape.
Synthesizing Non-Uniformly Excited Antenna Arrays Using Tiled Subarray Blocks
Authors: Mohammed Jafar Ramadhan
Published: November 2023

Conventionally, non-uniformly excited antenna arrays are synthesized by independently determining the excitation amplitude and phase of each single element. Such an approach is considered to be the most expensive and complex design method available. In this paper, the tilling technique is harnessed to synthesize non-uniformly excited antenna arrays. To apply this technique, the array elements are first divided into different subarray shapes, such as rectangles or squares known as tiles. The use of rectangular tile blocks instead of a single element architecture greatly simplifies the array design process and reduces array complexity. Next, the problem concerned with synthesizing sub-arrays comprising rectangular tile blocks is formulated and solved by using horizontal and vertical orientations of tiles having different shapes and sizes, and their larger integer expansions. The third approach to tiled design is a mixture of both previous tile architectures. A genetic algorithm is used to design such tiled arrays offering optimum sidelobe levels, beam width, directivity and taper efficiency. Simulation results demonstrated the effectiveness of the proposed tiled arrays.
Turkish Aid Allocation in Turbulent Times: Changes and Continuities in Turkish Aid Modality
Authors: MENGÜASLAN Hikmet
Published: October 2023

This paper investigates how Turkey has adjusted its foreign aid behavior over international and domestic shifts after the July 15 Coup Attempt. There have recently been exceptional developments in international/regional power structures whereby Turkey has a centrality, e.g., the war between Ukraine and Russia. Similarly, main pillars of Turkey’s foreign policy have been modified, best exemplified in increasingly strong sings of insecurity and lack of trust between Turkey and its erstwhile strategic partners. More importantly for Turkish aid allocation, a new framework – ‘Turkish-type Development Assistance Model’ (TDAM) has been introduced in late 2010s. As a result, the structural context in the early 2000s which has assisted Turkey in ascending the donor ranks has been gradually giving way to more ambiguous and elusive outlook for many types of international cooperation including foreign aid. To this background, the paper utilizes an interpretive analytical framework based on the critical analysis of key statements as well as on descriptive statistical analysis of databases (such as OECD and TIKA), and compares discursive, practical, and institutional patterns of Turkish aid allocation between the periods of 2003-2015 and 2016-2022 with the purpose of identifying the changes and continuities in Turkish development assistance with a macro-lens. It is concluded that given the growing polarization and competition in development landscape, TDAM should be seen as a robust and operational alternative for the maintenance of ‘relevant and impactful development assistance’ by embodying practical ways of ensuring mutual development without a secret agenda.

The battery has a capacity of 20-Ah with 48-V nominal voltage. The battery charger circuit uses the combination of an AC-DC converter in the form of a single-phase diode bridge rectifier and a full-bridge DC-DC converter, operating in medium frequency (MF) at 1 kHz. The full-bridge converter is controlled by a PWM controller SG3526 that sends its output to the 4 MOSFETs that built the converter. Due to operation at frequency of 1 kHz, the transformer’s core can use the laminated silicon steel sheet that is known as the E-I core. The battery is charged using the constant-current method by maintaining the charging current at a constant value. The functional test of the battery shows that by using 5-A constant current charging, the battery takes 80 minutes to its full condition from 50% capacity at the beginning.Keywords: lithium-ion battery charger, battery electric vehicles, medium frequency full-bridge DC-DC converter, silicon steel-core transformer

The author’s approach is proposed, based on the analysis of existing approaches to understanding the category of “municipal formation” and based on the totality of the interaction of four macro-systems (social, economic, municipal establishments, management). In the article sections of the methodological approach to assessment are substantiated and developed, requirements for their implementation are formulated, and approbation is carried out on the example of the municipality “Kirov City”. The novelty consists in the proposed methodological approach to assessing the socio-economic development of a municipality, which allows a comprehensive analysis of the results achieved over a long-term period in dynamics, including determining the level of competitiveness of the municipality and public assessment, and monitoring socio-economic development within the selected corridor of sustainable development in the long term. The results can be used by regional authorities and local governments to improve the effectiveness of management decisions, and by local stakeholders (business structures and the local population) to formulate development strategies taking into account trends and prospects for the development of the territory.

The development of Internet technology affects the dissemination of data, especially in vital government archives. This research uses a hybrid singular value decomposition (SVD) and discrete wavelet transform (DWT) method, which aims to protect the copyright of vital archives. The stages of the insertion and extraction process are carried out to test the effect of the alpha value on the quality (imperceptibility) and robustness of the inserted image by measuring the Peak Signal-to-Noise Ratio (PSNR), verifying similarity by measuring the Normalized Cross-Correlation (NC) and Structural Similarity Index (SSIM). The results of research with ten vital archives and a watermark protection logo in JPEG format with a size of 512x512 pixels obtained a maximum PSNR with a value of α = 0.01 of 41.0567 dB, NC of 0.98904, and SSIM of 0.98023 in the Cibereum Land Certificate. So, it can be proven that this method produces vital archive watermarks that can be extracted and are robust to JPEG compression attacks of 75%, median filtering 3x3, Gaussian noise 0.01, speckle noise 0.01, and salt and pepper noise 0.01 but not resistant to rotation 80 and cropping attacks 2%.

Eri silkworm (Samia cynthia ricini) is a potential silk producing insect in Indonesia. This study aimed to analyze the production performance of the S. c. ricini silkworm with cassava leaves feed (Manihot utilissima) and their cocoon productivity that mounting on different mountages (wood and carton),and also calculate the financial analysis. The silkworm was reared in altitude 176 m asl. Production performance observed were feed consumption (ingesta and digesta), larval productivity (length, breadth, and weight), and cocoon productivity (the effective rate of rearing and cocoon quality). Feed consumption and larval production were analyzed descriptively, the effective rate of rearing was compared using a t-test, cocoon quality was analyzed using a completely randomized design factorial 2 × 2 pattern. The first factor was sex and the second factor was mountages media that were used with three replications. Financial analysis was calculated using profit, R/C ratio, and BEP. The results showed the optimum consumption of cassava leaves during the study was 27.17 ± 2.39 g of feed ingestion and 19.15 ± 2.30 g of feed digestion. Mountages media did not significantly (P>0.05) influence the effective rate of rearing and cocoon quality. Cocoon weight, pupal weight, and shell ratio was affected by cocoon sex. Financial analysis calculation result showed that wood mountages gives the best value, with the profit value was Rp 21.877.819/year, R/C ratio was 1.61, BEP of yarn was 5.67 kg, BEP of eggs was 110.10 box.

Introduction: The diagnosis and management of systemic toxicity in patients following regional infiltration analgesia is of paramount importance. While the mechanism and risk factors have been elucidated in previous studies, we believe that due to the potentially life-threatening nature of this rare occurrence, a greater focus on diagnostic precision and management enhancements is warranted. Cases: Here, we describe three cases of LAST, the first in a 59 year old female following elective L4-L5 laminectomy and L5-S1 fusion, who suffered a cardiac arrest after receiving local Exparel and Marcaine at the time of closure; the second in a 69 year old woman following a rib block using local Exparel and Marcaine for the management of multiple rib fractures, who had a witnessed tonic-clonic seizure requiring intubation. The third patient is an 80-year-old male, who after an elective L4-L5 laminectomy and fusion, suffered a cardiac arrest after receiving local anesthetic (Exparel and Marcaine) at the time of closure. All patients were treated with intralipids and eventually recovered with no lasting deficits. Conclusion: LAST events most commonly occur in the first minutes after injection, and are characterized by CNS and cardiovascular toxicities, as seen in these patients. Delayed presentations up to several days post exposure have been described. These cases exposed the opportunity for education in early recognition and most important, the need to improve the availability of intralipids. Prompt recognition and access to intralipid is critical to the treatment of LAST, and education regarding this rare but life-threatening condition is needed in surgical and trauma centers.

In recent years, considerable interest has been evoked all over the world in the application of biological methods of controlling crop pests. Three of the major reasons for this have been: (1) the rapid development of resistance in insect and mite pests to many chemical pesticides, (2) the hazards that many of the recently developod organo- phosphorous and other toxic compounds pose to human and wild life and (3) the development of serious outbreaks subsequent to the use of a chemical pesticide, resulting from annihilation of existing natural enemy populations. Whatever other reasons there may be, it is gratifying to note that greater interest is now being taken in biological control and measures being taken to prevent further serious upsets in the balance of nature.

In the Lower Bhavani Project ayacut, Ragi was one of the major food crops raised under pre-project conditions. The soils of the ayacut are poor in nutrients resulting in low yield of crops. It was therefore, to be expected that the crops would respond to application of fertilizers under conditions of canal irrigation. To study the response of Ragi under irrigated conditions to different manurial treatments for fixing the optimum and economic manurial practice, manurial trials were conducted at the Agricultural Research Station, Bhavanisagar from 1960-61 to 1964-65 and the results of these trials are presented in this paper.
