Authors: Ismail Ade , Laela Ela
Published: March 2024

Optimization of the amount of production to maximize profits is still an obstacle to the growth of MSMEs in Indonesia. This study aims to determine the combination of the production amount of each Bakso Barokah Shop product type and the optimization of the income obtained. A linear program of simplex methods with POM-QM software is then used to obtain accurate research results. Based on the analysis results, the maximum profit per week of Barokah Meatball Shop is IDR 2,700,000, which is six times the production of Mercon meatballs. The calculation results show that the optimal meatball production is to focus on Mercon meatball production rather than other meatballs. The results of this study can be used as a decision-making consideration related to production problems to get optimal profits.
INDIA: THIRD-PARTY FUNDING IN PRACTICE OF INTERNATIONAL ARBITRATION
Authors:   Gujarat National Law University, India, GANDHI Vikas H.
Published: March 2024

High expenses are associated with international investment arbitration. To save the additional expenditure of the adjudication, parties typically prefer sponsored third-party ar bitration proceedings. On the other hand, the third-party funder is interested in funding the arbitration to benefit significantly from the dispute’s resolution. Interestingly, the arbitrators should be able to overlook the Third-Party Funding [TPF] issue to gain the necessary compe tency. Their competence is limited to disputes between the foreign investor and the host state only. This article discusses the concept and legal status of the third-party funder in arbitration. Keywords: Arbitration, third-party funding, expenses, adjudication, disputes, dispute resolution.

Documenting perceptions and misconceptions of shark conservation among students in Ghanaian coastal communities within the context of shark tourism
Authors: Amponsah Samuel
Published: March 2024

In Ghana, students have rarely been engaged in shark conservation programs. The study aimed to provide the perceptions and misconceptions about sharks among students in Ghana. From the Western region of Ghana, two senior high schools were visited from March to June 2023, and 111 questionnaires were administered to them with the assistance of a resident teacher. Most of these students believe that i) sharks do not eat humankind as food, ii) fishing activities do not affect shark behavior, iii) the decline in fish does not affect the shark population, and iv) fishermen in Ghana face a lot of shark attacks. On perceptions, most of the students perceived that i) shark fishing should not be stopped, ii) shark ecotourism will yield more money than shark fishing, and iii) MPAs will conserve shark population in Ghana. From the study, it was evident that knowledge and attitudes showed a strong positive correlation (r = 0.61). Therefore, incorporating shark related topics into the curricula of schools, taking students on educational tours to the fishing communities, and engaging them in outreach programs will enlighten their knowledge of sharks and foster their awareness of shark conservation and shark ecotourism in Ghana.
The Implications of Actovegin® in Sport: A Brief Review
Authors: Milovanovic Dragana , Stojanovic Emilija
Published: March 2024

Actovegin® (or Solcoseryl) is a deproteinized hemoderivative of calf’s blood, which contains more than 200 bioactive constituents. Screening and identification of biologically active molecule(s) is challenging due to the complexity of many constituents that may influence various cellular biochemical pathways and are found naturally in the body. Actovegin® comes in different forms including cream, gel, ointment, tablets, and injectable solution. Currently, according to section M2, Chemical and Physical Manipulation of the World Anti-Doping Code, intravenous injections of Actovegin® exceeding 100 ml is prohibited and further serial injections must be at least 12 hours apart. Although the performance-enhancing effects of Actovegin® are still anecdotal, the use of this drug has undoubtedly been widespread in sports for more than two decades. Existing findings provide promising results regarding the effect of Actovegin® in treating muscle injuries at the injected site. Further research exploring other forms of Actovegin ® (tablets, gel, cream) is encouraged to better understand the potential benefits of Actovegin® in applied sports settings.
Assessing tropism and genetic traits of carp oedema virus isolates to enhance detection strategies
Authors: Adamkowska Natalia , Kiełpińska Jolanta , Bergmann Sven Michael
Published: March 2024

Introduction

Carp oedema virus (CEV) is a relatively understudied poxvirus. It exhibits an affinity for gill and skin epithelial cells. Investigations were conducted into selected aspects of CEV biology, with a focus on determining cell and tissue tropism of CEV, acquiring gene sequences and updating CEV tests in fish tissues.

Material and Methods

A total of 238 common carp tissue samples from nine aquaculture farms were analysed. The study evaluated the efficacy of intermediate detection of CEV by real-time PCR and in situ hybridisation. The genes encoding protein P4a were sequenced, analysed and aligned in a phylogenetic tree using a molecular evolution model.

Results

In situ hybridisation revealed the necessity to validate the Centre for Environment, Fisheries and Aquaculture Science protocols for sampling for CEV detection and to use the tissues for which the virus has the highest tropism, namely the skin and kidneys, rather than solely the gills. The level of genetic variability was determined, and it was shown that CEV mutates systematically. The creation of two distinct phylogenetic clades confirms certain strains’ description as Polish isolates.

Conclusion

Determining the localisation of CEV genetic material in organs and tissues is pivotal for shaping the World Organisation for Animal Health guidelines. The utility of molecular diagnostics has been demonstrated in the skin and kidney of carp, in addition to the gills, impelling their inclusion in diagnostic protocols. The clusters identified in the phylogenetic tree offer valuable insights for developing the current PCR primers. The prevalence of CEV infection in aquaculture, juxtaposed with its notably lower detection in wild fish, underscores the significance of mandatory molecular diagnostic testing for CEV in carp farming.
Analysis of the season-dependent component in the evaluation of morphological and biochemical blood parameters in Shetland ponies of both sexes during exercise
Authors: Tkaczenko Halina , Lukash Oleksandr , Kurhaluk Natalia
Published: March 2024

Introduction

Determination of morphological and biochemical blood indices facilitates assessment of the health and welfare of horses, their nutrient demand, the effects of training already undertaken, and the horses’ suitability for exercise. Identification of the season-dependent components and the effects of sex and exercise on changes in frequently referenced haematological and biochemical parameters was the main goal of the current study.

Material and Methods

The blood morphology of 21 healthy adult Shetland ponies (11 mares and 10 stallions) aged 6.5 ± 1.4 years from the central Pomeranian region in Poland was analysed. Blood samples were taken once per season for one year.

Results

No statistically significant season-dependent differences were found in the blood morphology parameters in either mares or stallions before or after exercise. Beta-coefficient results revealed the strength and type of the relationship of red blood cell distribution width (RDW) and granulocyte count (GRA) with the season, of red blood cell count (RBC), haematocrit, mean corpuscular volume and mean platelet volume with the sex, and of RDW, white blood cell count, GRA and RBC with the exercise factor. Biomarkers demonstrating the relationship between aerobic and anaerobic levels of energy metabolism in the blood did not show any sex dependency in regression analysis.

Conclusion

The sex-independence of energy metabolism biomarkers may indicate the universality of these parameters. Both seasonality itself and its combination with the exercise factor took part in the formation of effective adaptive reactions for maintenance of morphological blood indices in the ponies during exercise.
Phylogenetic analysis of the trypanosomatid parasite Lotmaria passim in honey bees (Apis mellifera) in Poland
Authors: Iller Maria , Lipczyńska-Ilczuk Karolina , Sokół Rajmund , Borsuk Grzegorz , Bancerz-Kisiel Agata
Published: March 2024

Introduction

Lotmaria passim (L. passim) is a single-celled flagellate which colonises the bee gastrointestinal tract and is highly prevalent in honey bees. This parasite is associated with colony losses. Honey bee (Apis mellifera) colonies were sampled from five apiaries in the north-eastern part of Poland for the phylogenetic analysis of L. passim.

Material and Methods

Each apiary consisted of approximately 60 bee colonies, of which 20 were randomly selected. Samples of 60 differently aged worker bees were collected from each colony and pooled. A total of 100 bee colonies from five apiaries were examined. Protozoa of the Trypanosomatidae family were identified by PCR. L. passim was detected in 47 (47%) of the samples. The 18S ribosomal (r) RNA amplicons of L. passim were sequenced by a commercial service. Their sequences were analysed with BLASTN and noted to be compatible with the GenBank sequences of this region of the organism’s genome. A sequence analysis was performed using the BioEdit Sequence Alignment Editor and Clustal W software.

Results

The amplicon sequences of L. passim were 100% homologous with the sequences deposited in GenBank under accession numbers KM066243.1., KJ684964.1 and KM980181.1.

Conclusion

This is the first study to perform a phylogenetic analysis of L. passim in Polish honey bees. The analysis demonstrated high levels of genetic similarity between isolates of L. passim colonising apiaries in the north-eastern region of Poland.
Serological characterisation of Lagovirus virus-like particles originating from native and mutated VP60 of rabbit haemorrhagic disease virus 2 and European brown hare syndrome virus
Authors: Krejmer-Rąbalska Martyna , Peplińska Marta , Szewczyk Bogusław , Fitzner Andrzej
Published: March 2024

Introduction

Since lagoviruses cannot be cultivated in vitro, using expression systems is an alternative and promising way of producing diagnostic viral antigens. It opens up their use as active immunogens for vaccine production.

Material and Methods

Virus-like particles (VLPs) were produced in a baculovirus expression system in Spodoptera frugiperda 9 (Sf9) insect cells based on wild-type and mutated variants of the virus capsid VP60 protein from a Polish strain of European brown hare syndrome virus (EBHSV) and wild-type and mutated versions of this protein from a Polish strain of rabbit haemorrhagic disease virus 2 (RHDV2). The mutations were the substitution of an arginylglycylaspartic acid (Arg-Gly-Asp/RGD) motif in the P2 subdomain and, in the S or P2 domain, the substitution of three lysines. The VLPs were purified with sucrose gradient ultracentrifugation.

Results

Protein production was confirmed by Western blot analysis using rabbit or hare sera and ELISA tests with different types of monoclonal antibody. The haemagglutination properties of some VLPs were also evaluated. Electron microscopy of wild-type EBHSV, wild-type RHDV2 and the four VP60 variants produced in this experiment revealed the formation of characteristic VLP structures.

Conclusion

For the first time, mutated VLPs of RHDV2 with an RGD motif in the VP60 sequence were obtained, which could potentially be used to deliver cargo to eukaryotic cells. Virus-like particles based on the VP60 proteins of EBHSV and RHDV with a three-lysine substitution in the S or P2 domains were also obtained. Potential exists for VLPs of EBHSV and RHDV2 as vaccine candidates.
Transforming Megacities: Value and Impacts of Mixed-Use Developments with Multi-Criteria Decision-Making
Authors: Valero Alfonso
Published: March 2024

This research article explores the valuation of mixed-use developments and their impact on urban planning and city regeneration. The study introduces a Multi-Criteria Decision Making (MCDM) methodology to analyze complex buildings developed in Shanghai from 2009 to 2019. Two MCDM appraisals are offered in different developments using three groups of key indicators that served as benchmarks for other Chinese clusters and global megacities. The article addresses two primary research questions: how mixed-use assets can be assessed using MCDM, and what the key performance indicators and factors contributing to the success of mixed-use developments are. The findings highlight the importance of connectivity, previous real estate experience, ESG strategies, international branding, architectural design, financial metrics, and adaptability of the real estate industry in evaluating mixed-use assets. The study provides insight to stakeholders involved in real estate development, including urban planners, developers, and investors, enabling them to make informed decisions and improve sustainable practices. The research also highlights the importance of considering ESG principles, community benefits, and long-term strategies when assessing mixed-use developments to drive social change and contribute to urban regeneration.
Exploring Public Interest in Limited-Use Areas and Compensation from Airports in Poland: A Google Trends Analysis
Authors: Bełej Mirosław
Published: March 2024

This article evaluates online social behavior regarding the establishment of limited-use areas (LUAs) around the airports in Warsaw and Gdansk. The study relied mainly on an analysis of Google Trends statistics, in particular the dynamics of keyword searches. The article suggests that assessments of online behavior can provide a deeper understanding of social behavior. The study involved an OLS regression analysis and a causal impact analysis of the intervention based on a Bayesian structural time-series model. This article analyses different phases of an information society's activity, from the introduction of LUAs around airports to the deadline for submitting compensation claims. The results indicate that the number of searches for the keyword "compensation" increased significantly after the introduction of LUAs and that RSV decreased after the end of the compensation process, which confirms that the intervention significantly influenced the analyzed time series.
Massive primary pulmonary artery rhabomyosarcoma: A case report
Authors: Rashidi Farid , Bilehjani Eissa , Mousavi-Aghdas Seyed Ali , Parvizi Rezayat
Published: March 2024

Background:

Pulmonary artery sarcomas (PAS) are rare tumours causing an insidiously progressive obstruction of the pulmonary circulation. The clinical presentation is often indistinguishable from chronic thromboembolic pulmonary hypertension (CTEPH). However, the atypical appearance of a heterogeneous filling defect in CT pulmonary angiography (CTPA) should prompt further investigation.

Case Presentation:

A previously healthy young man presented with massive haemoptysis, acute respiratory distress, and progressive exertional dyspnea since the year before. Echocardiography demonstrated severe right ventricular dysfunction and highly probable pulmonary hypertension. CTPA revealed an extensive filling defect with an appearance concerning PAS. Due to syncopal episodes at rest, the patient underwent urgent pulmonary artery endarterectomy (PEA). A massive tree-like tumour was excised as a result. Post-operatively, reperfusion injury and refractory pulmonary oedema mandated extracorporeal membrane oxygenation (ECMO). Unfortunately, ECMO was complicated with massive haemolysis and acute kidney injury. The patient succumbed to multi-organ failure. Through tissue analysis established a diagnosis of embryonal rhabdomyosarcoma.

Discussion:

Unfortunately, the patient had not reached out for his worsening dyspnea. PASs should not be mistaken for a thrombus and anticoagulation should be avoided. The urgent condition precluded biopsy and tissue diagnosis. Similarly, neoadjuvant chemotherapy was not feasible. Post-operatively, reperfusion injury and pulmonary oedema ensued, which mandated ECMO. This complication should be anticipated preoperatively. There is a need for more data on PASs to establish a consensus for management.

Recent empirical studies have identified the presence of the Turn of the Month (TOM) effect on various stock markets. This effect is a yell-knoYn calendar anomaly in stock markets, characterized by higher returns and increased trading volume around the beginning of each month. The researchers have proposed several explanations for this anomaly, includ- ing factors such as increased liquidity, YindoY dressing practices, and neys announcements. This study focuses on investigating the TOM effect in the Indian stock market, specifically focusing on size of firms and trading activity by individual investors, as Yell as domestic and foreign institutional investors. We analysed the closing prices of four indices (Nifty 50, S&P BSE Sensex, Nifty SmallCap 50, and BSE SmallCap) from April 2007 to February 2023. Our analysis involved using parametric t-tests and non-parametric Mann-Whitney U tests to assess the significance of our findings. The results indicate that the TOM effect is indeed significant in the Indian stock market, Yith higher returns observed during the days surrounding the TOM. Furthermore, this effect is more pronounced in smaller indices com- pared to larger ones. Additionally, Ye found that domestic institutional investors engage in significant trading activity toYards the end of the trading month, Yhile individual investors do not demonstrate the same pattern. Foreign investors also exhibit notable differences in trading activity betYeen the TOM and the rest of the month.

Authors: Wahyuningtyas Endah Tri , Majidi Lalu Muhammad Syahril , Murtadho Muis , Musriha  , Susesti Dina Anggraeni , Primasari Niken Savitri
Published: March 2024

Purpose: This research aims to investigate the relationship between Environmental, Social, and Governance (ESG) performance and capital structure, using Debt-to-Equity Ratio (DER) and Debt-to-Asset Ratio (DAR) proxies, in Indonesia and Malaysia. The study seeks to address the gap in the literature by exploring how ESG factors influence the capital structure decisions of both financial and non-financial companies in these countries. Additionally, the research analyzes the impact of ESG performance on the cost of equity and cost of debt.
 
Methods: The research utilizes secondary data extracted from annual reports and sustainability reports spanning from 2015 to 2020. A total of 102 companies, comprising 59 Indonesian companies and 52 Malaysian companies registered on CSRHub, are included in the analysis. ESG performance is assessed based on community, environmental, social, and governance indicators. Capital structure is measured using DER and DAR proxies. Statistical analysis techniques are employed to examine the relationship between ESG performance and capital structure, as well as its impact on the cost of equity and cost of debt.
 
Results and Discussion: The research findings indicate that community, environmental, social, and governance performance exhibit a negative effect on the cost of equity, suggesting that companies with stronger ESG performance experience lower costs of equity financing. However, these ESG factors do not significantly affect the cost of debt. This implies that while ESG performance may influence equity holders' perceptions of risk and return, it may not have a direct impact on the cost of debt financing for companies in Indonesia and Malaysia.
 
Implications of the Research: The results of this research have important implications for companies, investors, and policymakers interested in understanding the relationship between ESG performance, capital structure decisions, and financing costs. By demonstrating the impact of ESG factors on the cost of equity, the findings underscore the importance of integrating sustainability considerations into financial decision-making processes. Moreover, the research highlights the need for further investigation into the mechanisms through which ESG performance influences capital structure and financing costs.
 
Originality/Value: This study contributes to the literature by offering novel insights into the relationship between ESG performance and capital structure in Indonesia and Malaysia. By examining the impact of ESG factors on both equity and debt financing costs, the research expands our understanding of how sustainability considerations influence corporate financial decisions. The findings provide valuable guidance for companies seeking to enhance their ESG performance and optimize their capital structure, ultimately contributing to more sustainable and responsible business practices in emerging markets.

Published: March 2024

ABSTRACT

Background and Objective: Replacing lost dentin with an appropriate substitute has been challenging in recent years. Biodentine and conventional glass ionomers are used as dentin replacement materials. This study aimed to compare the Vickers microhardness (VHN), diametral tensile strength (DTS), and setting time of Biodentine and glass ionomer cement (GIC).
Methods: This experimental study was conducted in the Department of Science of Dental Materials at Fatima Memorial College of Dentistry, Lahore, in collaboration with the Interdisciplinary Research Centre of Biomedical Materials, COMSATS Lahore from December 2022 to March 2023. A total of fifty disc-shaped samples (4 × 2 mm) of Biodentine and GIC Gold Label 2 were fabricated to assess the VHN, DTS, and setting time after immersion in distilled water for 1 hour and after 3 days. Data were analyzed by applying the paired and independent t-tests using Statistical Package for Social Sciences 26.0.
Results: The mean VHN value of Biodentine and GIC Gold Label 2 cement was 23.4 ± 1.5 and 17.5 ± 1.27 after 1 hour and 31.9 ± 1.66 and 29.6 ± 1.58 after 3 days, respectively. DTS of Biodentine [7.0 ± 0.91 mega pascal (MPa)] was significantly greater than GIC Gold label 2 (5.5 ± 0.68 MPa) after 1 hour (p < 0.05). However, after 3 days, there was a slight increase in the DTS of Biodentine (9.3 ± 1.53 MPa) while compared to GIC Gold label 2 (8.2 ± 1.0 MPa) and this difference was not statistically significant (p > 0.05). Biodentine had a higher setting time than GIC Gold label 2, with an initial setting time of 6.7 minutes compared to 2.9 minutes.
Conclusion: GIC Gold label 2 has a shorter setting time than the but Biodentine which, however, showed higher Vicker’s microhardness and DTS. Therefore, Biodentine may be a more suitable substitute for dentine replacement than the GIC Gold label 2.
Fibroadenoma of the Breast Occurring Synchronously in Twin Sisters- A Case Report
Authors: Iqbal Firdous , Gul-e-Rana
Published: March 2024

Fibroadenomas (FAs) are the most common benign tumors of the breast in young females. Most of the time, it presents as a well-circumscribed, painless, firm to hard, mobile, and slow-growing unilateral or bilateral breast lump. The median age of its presentation is 25 years with rare occurrence after menopause. The exact etiology of FA is still unclear. Unopposed estrogen in the growing breasts of young females is considered as a main factor in its pathogenesis. Family history and development of FA in identical twins are suggestive of genetic contribution to the pathogenesis of these tumors.

This is a case report of young twin sisters who presented at a tertiary care hospital in Lahore with a complaint of a synchronously developed unilateral breast lump. Fine needle aspiration cytology was planned after taking a detailed history and clinical examination of both patients. Diagnosis of FA was confirmed radiologically and through cytological examination. To the best of the authors’ knowledge, this is the first case of its kind reported from Pakistan.
Need to revisit ethics training of doctors for effectively serving rural communities; a review
Authors: Tarar Zunaira Haris , Chaudhry Saima
Published: March 2024

The dawn of globalization has produced the need for doctors who are prepared to facilitate communities regardless of their ethical constraints. Medical ethics is an integral component of undergraduate training and has gradually affirmed that different ethical issues are encountered by doctors within rural settings and urban areas. There is a strong need to acknowledge that ethics varies as we move not only from urban or rural settings, but also as we move across different regions, countries, and continents. There have been various studies conducted in different regions of the world to highlight the presence of different ethical issues arising in various settings. This review aims to highlight common ethical issues faced by general practitioners in rural settings as various regions have different customs which influence their decision-making skills and the patients’ relationship with their practitioner. This gives rise to the necessary task of providing training for doctors so that they are better equipped to handle these challenging scenarios in primary health care domains in order to facilitate optimal health care for patients from diverse backgrounds in different settings ethically and professionally.

: Strontium hexaferrite (SrFe12O19) materials were synthesized through the hydrothermal method with conditions at R= (Fe3++ Sr2+)/(OH ̶) ratio of 2 to 4 (R ratio of 1/2, 1/3 and 1/4 were, respectively abbreviated to M2, M3 and M4). R has been examined by employing Fe(NO3)3 and Sr(NO3)2 as the initial materials. The effects of R ratio on the structure, particle size, magnetic and microwave-absorbing properties of the samples were studied. The coercivity and saturation magnetization of M4 sample reach 5.2 kOe and 58.7 emu/g, respectively. The optimal reflection loss of the M4 at the thickness of 1.5 mm reached a value as large as - 48.27 dB in the frequency range of 2 to 18 GHz. The improvement in microwave absorption performance of M4 sample compared to M2 and M3 was mainly resulted from the increased magnetic properties with increasing R ratio.

By using cyclic voltammetry (CV) and chronoamperometry (CA) techniques, the thermodynamics and kinetics of palladium electrodeposition on glassy carbon electrode (GCE) in deep eutectic solvent were studied. The Pd electrodeposition process via progressive 3D nucleation mechanism was controlled by the diffusion. Non-linear fitting methods were applied to obtain the kinetic parameters in the light of Harrison – Thirsk (H-T) and Scharifker – Hills (S-H) models for 3D nucleation and growth process. From that, the diffusion coefficient of Pd (II) in reline at ambient temperature was calculated by two different ways, and the obtained results showed that it is of cm2/s by using CV. Moreover, some important parameters such as the number density of active sites on the electrode surface (No) and the nucleation frequency per active site (A) were estimated by fitting experimental CAs data with Scharifker-Mostany model.

Authors: Quan Tran Quoc , Hung Nguyen Dang , Thang Vu Duc
Published: March 2024

In this work we studied investigates the nonlinear vibrations of a rectangular saturated porous functionally graded (FG) plate on elastic foundations in thermal environment. The mechanical properties of the saturated porous material vary smoothly with the thickness in three different distributions of porosity including uniform, symmetrically irregular, and asymmetrically irregular. The basic equations are employed by the Reddy’s higher order shear deformation theory, incorporating the geometrically nonlinear von Kármán strain-displacement relationship, stress-strain relations based on the elastic theory for porous materials by Biot, and an analytical solution obtained through the Galerkin method and Airy’s stress function for the simply supported plate. The influence of the geometrical and material parameters, elastic foundations and temperature increment on the nonlinear vibrations of the saturated porous FG plate were specifically evaluated through numerical investigations.
