Authors: Horváth Gábor
Published: September 2023

Az elmúlt húsz évben folytatott kutatások eredményeként egyre több repülőtéren találkozhatunk a helyfüggetlen toronyirányítási rendszer (a továbbiakban: Remote Tower) technológiával, így túlzás nélkül állíthatjuk, hogy mára valósággá vált a helyszíntől független repülőtéri irányító szolgáltatások biztosítása. A technológiában rejlő potenciál azonban nemcsak a polgári, hanem a katonai légiforgalmi szolgáltatások konvencionális működési rendjét is átalakíthatja. A szerző, az alábbi tanulmány keretében az utóbbi alkalmazási terület reziliens1 aspektusát mutatja be.

Authors: Kurul Ramazan , Dıramalı Murat , Özdemir Dilruba , Erdoğan Kevser Ezgi
Published: September 2023

Objectives: Resin printing is a rapidly growing technology with a diverse range of applications. This study aims to examine the usability of 3D resin printed models in anatomy education. Methods: The study included 84 students who were randomly assigned to either a 3D resin print group (n=42) or a plastic model group (n=42) based on their sex, lateralization, anatomy quiz scores, and Purdue spatial visualization test rotations scores. After attending a lecture, each participant examined an original sacrum and either a 3D printed or a plastic model, depending on their group. The participants were then asked to compare the models to the original using a visual analog scale (VAS) questionnaire, which consisted of four questions about the model’s weight, anatomical accuracy, level of detail, and texture quality. The participants’ ability to identify the models was evaluated using a 3-point Likert scale. Results: The results showed that the 3D printed model had significantly higher ratings than the plastic model in terms of weight, level of detail, and texture quality (p<0.05). There was no significant difference in accuracy scores (p>0.05) or the participants’ ability to identify the models (p>0.05). Conclusion: 3D resin printed models are superior to plastic models in some aspects. These results suggest that 3D resin printed model can be used as in the conventional anatomy training approach.
A Study on Determinants of Profitability of Private Banks in Bangladesh: Empirical Evidence from Panel Data Estimation.
Authors: Biswas Gautam Kumar
Published: September 2023

This study seeks to reveal the determinants of profit of private banks in Bangladesh using a panel data set spanning from 2005-2018. In my study, I used Return on Equity (ROE) and Return on Assets (ROA) as the proxies for profit of banks. Using the panel data model, the study found that Loan to Asset Ratio (LAR) and Capital Adequacy Ratio (CAR) had a positive association with the profit of banks, while the growth rate of Gross Domestic Product (GDP) had a negative effect on banks profit. But the other macroeconomic variable, inflation, didn’t have any impact on profit for banks operating in Bangladesh. The findings of the study can help the management of banks and policymakers achieve efficiency and earn higher profits.

This work corresponds to an analysis of the scientific production on the species Emerita brasiliensis Schmitt, 1935 through bibliometric indicators. Emerita brasiliensis is a decapod crustacean belonging to the Hippidae family. This species inhabits the intertidal benthic zone of beaches and, despite being distributed in great abundance along the Brazilian coast, has been suffering anthropic impacts on its habitat. The research object was chosen due to the need to understand the level of knowledge about the characteristics of this organism, which point to it as a potential bioindicator, in addition to having great ecological importance on sandy beaches and having considerable relevance in marine food chains. Bibliometric research is a method of quantitative analysis on a given subject. Through this method, it was possible to detect different lines of research on the subject, recognize limitations and determine patterns to research on this species. The collected data expose the contribution of the scientific community to that area of study. Thus, the objective of this study is to evaluate the scientific production on the species Emerita brasiliensis based on the analysis of articles published in journals or conference proceedings indexed in the Scopus database. The amount of information collected corresponds to a search of articles published over the 20 years (1981-2021).

Authors: AKÇURU Sedat , ERDEMİR Mustafa
Published: September 2023

The aim of the study is to reveal the experiences of lecturers regarding this phenomenon in the process of transition to distance education due to the Covid-19 pandemic and to compare these experiences with face-to-face education. For this purpose, a phenomenological design, which is a method of qualitative research, was used in the study, and semi-structured interviews were conducted with 18 lecturers. The interviews were subjected to content analysis and as a result of the analysis, the lecturers' views on distance education were revealed. The lecturers evaluated distance education negatively because of limited interaction, lack of communication, insufficient technological tools and equipment, technical infrastructure problems, measurement and evaluation not reflecting the reality, and this education model is not suitable for applied courses. In the distance education process, there were differences compared to face-to-face education in the general teaching of the course, the methods and techniques used, the activity of the stakeholders, the time used for a course and the completion of the content of the course planned until the end of the semester. The advantages of face-to-face education were listed as the ease of involving students in the course process, the fact that validity and reliability reflect the reality, and the ease of interaction and communication.
Austeridad y defensa: los discursos de las élites económicas centroamericanas durante la pandemia
Authors: Robles-Rivera Francisco , Alvarenga Ximena , Fuchs Gustavo
Published: September 2023

Las élites económicas centroamericanas han sido reacias a políticas redistributivas y democráticas aun en contextos de crisis. Este artículo analiza los discursos de las élites económicas durante los primeros seis meses de la pandemia del covid-19 en Centroamérica. Metodológicamente analiza los discursos contenidos en las declaraciones públicas en materia económica y fiscal realizadas por las principales cámaras empresariales de cada país para la atención de la emergencia. El artículo argumenta que esas élites ubicaron sus discursos en dos escenarios: a) los discursos que priorizaron una agenda de austeridad, y que en menor medida reflejaron tensiones con los gobiernos, y b) los discursos que llamaron a la defensa de las cámaras empresariales y que reflejaron más tensiones discursivas con los gobiernos.

Authors: Mustansar Nayab , Rafi Rizwan
Published: September 2023

Coronaviruses are zoonotic, meaning they are transmitted between animals and people. Detailed investigations found that SARS-CoV was transmitted from civet cats to humans and MERS-CoV from dromedary camels to humans. Several known coronaviruses are circulating in animals that have not yet infected humans. Common signs of infection include respiratory symptoms, fever, and cough, shortness of breath and breathing difficulties. In more severe cases, infection can cause pneumonia, severe acute respiratory syndrome, kidney failure and even death. In this article we have surveyed and did surveillance of 10 military camps of CPEC Chinese officials. No confirmed case would have been found though a lot of suspected cases were put into quarantine for further investigation. Moreover, WHO defined strategic Objectives and Preparedness and response redefined. Public recommendations and awareness was also discussed in detail.
Synergistic antiproliferative effect of mechlorethamine and amyloid beta-peptide on the human lung cancer cell line H441
Authors: L. Lukov Georgi , T Tuthill
Published: September 2023

Mechlorethamine (ME) is an antineoplastic agent which has been in clinical use for more than six decades. ME therapy is associated with high toxicity, and it is often in combination with other therapeutics. The use of additional antiproliferative agents could allow the use of ME at lower concentrations, which could lead to comparable therapeutic results, but with lower toxicity. Recent findings have shown that the amyloid β-peptide (Aβ) has antiproliferative properties toward the human cancer cell line, H441 among others. In this study, the cooperative antiproliferative effect of Aβ and ME on the human cell line, H441, isolated from papillary adenocarcinoma lung tissue, was measured. Cells were cultured for 72 hours under standard culturing conditions in growth media containing either Aβ (2 µM), a very low dose of ME (0.2 µM), or both agents combined. We observed a 48% decrease in cell proliferation when Aβ and ME were used simultaneously, compared to 30% and 33% when ME or Aβ, respectively, were used independently. The study demonstrates that the antiproliferative properties of Aβ can augment the anticancer effect of toxic chemotherapeutics such as ME when used at lower doses.

In September 1986, under the auspices of the refugee Studies Programme, an international seminar on the implementation of the OAU and UN Conventions and Domestic Legislation Concerning the Rights and Obligations of Refugees in Africa was held at Oxford Univerity. There were thirty-five participants from Africa, including academics and officials nominated by seventeen African governments. A number of eminent scholars, government officials, refugees, and agency personnel from Asia, Europe and the Americas were involved. The seminar focused chiefly on refugees in Africa, but one of its purposes was to acquaint participants with law, policy, and practice in all the regions of the world affected by mass exodus. Each African government representative presented a paper on the legal situation for refugees in their country. Guest speakers reported on the situation for refugees in Southeast Asia, Pakistan, Canada, Europe, Central America, Britain, the US, and Mexico. Through films and lectures, the participants were able to consider a range of related topics: for instance, how different development models lead to oppression; the psychological consequences of authoritarian regimes; the rights of the child; the special problems of women refugees; torture; and the problems of adaptation to life in asylum.

As Síndromes Poliglandulares Autoimunes (SPA) são consideradas endocrinopatias raras em que ocorrem alterações autoimunes nas glândulas endócrinas, acompanhadas de outras doenças não endócrinas. Tendo em vista a complexidade de associações em cada subtipo, suas particularidades e gênese dos mecanismos envolvidos, este artigo  busca, através de uma meta-analise, equacionar seus aspectos descritivos mais atuais e importantes para a prática clínica. As SPA podem ser classificadas nos tipos I, II, III e IV de acordo com a idade de início e os órgãos afetados. Interações complexas entre fatores genéticos, epigenéticos e ambientais provavelmente contribuem para o desenvolvimento dessas síndromes, que idealmente devem ser diagnosticadas em estágios iniciais, dada a sua alta morbidade e mortalidade. O tratamento adequado de cada uma das alterações é essencial para preservar a qualidade de vida dos pacientes.

Published: September 2023

En los Andes occidentales del sur del Ecuador existen remanentes de bosques tropicales montanos andinos, BTMA, que merecen ser estudiados ecológicamente para valorarlos y conservarlos. El objetivo de esta investigación fue describir la diferencia de parámetros taxonómicos y funcionales de la vegetación arbórea y, además, explicar su relación con variables predictoras. Se utilizaron predictoras de clima, de suelos y una autocorrelación espacial para explicar las diferencias en la composición, diversidad, densidad arbórea, biomasa y rasgos funcionales entre dos tipos de BTMA: bosque siempreverde montano (BSM) y bosque siempreverde montano alto (BSMA). La diferencia en la composición de especies fue descrita con análisis de similitudes y escalamiento multidimensional no métrico. Las diferencias en la diversidad, densidad, biomasa y rasgos funcionales se evaluaron mediante pruebas de medias con t de Student. La relación entre la composición de especies y variables predictoras fue analizada con partición de varianza, y la densidad arbórea, biomasa aérea y rasgos funcionales, con modelos lineales generalizados. La composición de especies fue diferente entre los dos tipos de bosques. Estas diferencias fueron explicadas por el clima y la autocorrelación espacial. La densidad arbórea y la biomasa aérea fueron superiores en el BSMA. El promedio ponderado del área foliar (AF) fue superior en el BSM, y el área foliar específica (AFE) fue mayor en el BSMA. La composición de especies fue explicada por la precipitación media anual (PMA) y la temperatura media anual (TMA); la densidad arbórea, por la TMA, la densidad aparente (DA) y la materia orgánica; la biomasa arbórea aérea, por la TMA; el AF, por la TMA y la DA, y el AFE, por la PMA. Se concluye que los parámetros de la vegetación varían en gradientes altitudinales pequeños, donde existe heterogeneidad ambiental condicionada por el clima y ciertas variables de los suelos.

Published: September 2023

Self-assembling peptides are attractive alternatives in biomaterial science, due to their variability and biocompatibility. Unfortunately, such peptides have poor solubility, their purification and synthesis and overall handling is challenging. Our goal was to develop a cage peptide design with which full control over self-assembling can be achieved. Theoretically, aggregation can be supressed if the amino acid side chains in critical positions are temporally masked. Considering several biological and synthetic requirements a photosensitive protecting group, p-hydroxy-phenacyl (pHP) was chosen as a “masking” moiety. To test our theory, EAK16-II was chosen as our model self-assembling peptide and a caged derivative containing photolabile pHP groups was synthesised. Both spectroscopic and in vitro experiments on A2058 melanoma cells confirmed our hypothesis, that the caged-EAK16-II peptide has good solubility, and the hydrogel formed after photolysis resulted in similar viability and cell aggregate formation of melanoma cells as the native EAK16-II-based hydrogel.
How Nanoparticle Size and Bubble Merging is Governed by Short-Range Spatially-Controlled Double-Beam Laser Ablation in Liquids
Authors: Riahi Farbod , Doñate-Buendía Carlos , Barcikowski Stephan , Gökce Bilal
Published: September 2023

Pulsed laser ablation in liquid (LAL) is a method for synthesizing nanoparticles with controlled composition and high purity. However, current research predominantly examines isolated cavitation bubbles, overlooking real-world LAL scenarios where numerous bubbles interact simultaneously. This study addresses this gap by investigating the effects of short-range micrometric spatially controlled double-pulse laser ablation in liquids on nanoparticle size distribution. Gold and YAG are used as model materials, and a dimensionless parameter, H*, is introduced to quantify the ratio between double bubble spatial separation and their maximum height. This parameter correlates with cavitation bubble merging time, bubble volume change rate, and subsequent nanoparticle size increase. Shadowgraphs provide valuable insights into bubble contact and fusion dynamics, showcasing phase separation by a thin water film and subsequent merging into a single bubble. Notably, a two-fold increase in nanoparticle size is observed for both Au and YAG at H* = 0.25. Our research indicates a strong association between nanoparticle size trends and cavitation bubble volume rate change, particularly emphasized at H* = 0.25. Understanding the dynamics of neighboring bubbles during LAL emphasizes the relevance of lateral pulse distances in dual-beam LAL, impacting particle size distribution in a distance-dependent manner.
Computational Examination of Transition Metal-Salen Complexes for the Reduction of CO2
Authors: McCarver Gavin , Yildirim Taner , Zhou Wei
Published: September 2023

In this comprehensive study, we investigated the catalytic potential of seven transition metal-salen (TM-salen) complexes for the reduction of CO2 using ab initio methods. Our findings revealed distinct catalytic behavior among the TM-salen complexes, driven by their electronic and geometric properties. The reduction of hydrogen to H2 was most favorable on Mn-salen and Cu-salen complexes, indicating potential competition with CO2 reduction. Notably, later TM-salen complexes (Co, Ni, Cu, Zn) exhibited higher energy requirements for the initial CO2 reduction, whereas Mn- and Fe-salen complexes demonstrated potential-controlled selectivity, favoring CO2 reduction beyond HCOOH at specific thresholds. Our results highlight Cr-salen and Fe-salen complexes as promising candidates for CO2RR catalysts due to their reduced competition with hydrogen reduction and low overpotentials for CO2 reduction. Furthermore, the distinct reaction profiles of TM-salen complexes offer valuable insights for the design and development of efficient catalysts for sustainable CO2 conversion and other chemical transformations. These findings provide a foundation for further exploration and optimization of TM-salen complexes as viable catalysts in environmental and energy-related applications.

Published: September 2023

The Ca/Mg-biochar hybrids have outstanding phosphate adsorption abilities over most modified adsorbents when applied in stoichiometric amounts; recent MgO-functionalized lignin-based bio-charcoal reported the highest phosphate uptake (906.8 mg/g). Apart from large phosphate uptake, Ca/Mg-rich biochars offer a variety of advantages like non-renewable phosphate recovery, soil amendment, resource utilization, waste management and conversion, etc. However, complex preparation methods, expensive metallic reagents, and/or the need for energy-intensive equipment limit the economic interest for these composites. Therefore, in this review, the latest Mg/Ca-biochar synthesis methods are evaluated, emphasizing the value of utilizing green/ waste materials and reagent-free fabrication methods leading to sustainable development. Among the loaded elements, Ca and Mg are employed to provide a prospect of high phosphate uptake as well as increased phosphate recovery. The spent Ca/Mg-biochar hybrids with large phosphate loadings can be implemented as safe slow-release phosphate fertilizers or can be recycled using practical methods; a recent study found that basification followed by tap water addition recovered over 82% phosphate, after reusing the absorbent for 4 cycles, without affecting its stability. At the end of the review, the real-time applications, and limitations of these biochars, important knowledge gaps in the literature, and future directions are summarized, aiming to promote the sustainable utilization of Ca/Mg-modified biochar in various environmental applications.
The Effect of the Pandemic on the RMG Export of Bangladesh: Exploring the Economic Channels of Transmission
Authors: Banik Banna
Published: September 2023

This study aims to empirically analyse the potential long-run and short-run effects of the COVID-19 pandemic on the ready-made garments (RMG) export growth of Bangladesh. We distinguish two transmission channels: credit growth and degree of openness to trade, through which the pandemic could affect the RMG export, using monthly time series data from June 2009 to August 2020. We employ a bounds test approach to the autoregressive distributed lag (ARDL) cointegration method. The bounds test specifies long-run and short-run relationships between credit growth, openness, and RMG exports. We found that the pandemic has a significant negative effect in the short run but a positive impact on export through these transmission channels in the long run. Thus, more credit support to this sector and opening up the economy for international trade is essential for the total recovery of the RMG export.
How would indian economy become worth $ 5 trillion? Performance of selected variables for previous few years conveys a different state of affairs
Authors: Bhalla N. S. , Sidhu T. S. , Sanjeev  , Shruti Sarin
Published: September 2023

Now a days, it has been frequently listened that Indian Economy would become worth $5 trillion by the end of 2024. The present government seems to be all committed to reach this mammoth target only in dialogues and speeches. Success or failure of any economy depends upon the efficiency and effectiveness of the government because the government plans, formulates policies or strategies, implements the same and deploys resources. No doubts, the external environment such as conditions prevalent in the global economy also put impact on the individual economies yet the government has a crucial role to play therein. Through this article, the authors have tried to evaluate the Indian economy on the basis of the performance of selected seven variables (GDP growth rate, Fiscal Deficit as % of GDP, Inflation Rate (Retail Consumer Price Index and wholesale Price index), Volume of Foreign Exchange Reserves, Output Growth Rate of Primary, Secondary and Tertiary Sectors, International Hunger Index) for the period of three years starting from 2016-17 to 2018-19. This article is based on the secondary data accessed from various websites and articles available online through internet. The performance of Indian economy is worth appreciating as far as Fiscal Deficit, Inflation and Foreign Exchange reserves are concerned, but the position for the rest of the variables has not been satisfactory. So the target of becoming $ 5 trillion economy seems too difficult to be achieved, if not impossible.

Forensic Interviews with Children: Exploring the Kinds of Information Interviewers Prompt
for and those which Children Provide
Authors:   , Shearer Kelly
Published: September 2023

Child maltreatment court cases often rely heavily on children’s eyewitness testimony as primary evidence, because alternative or corroborating evidence is often unavailable. When obtaining children's testimony, forensic interviewers are faced with the challenging task of gathering the specific details required by the criminal justice system, whilst managing children's developmental capabilities. Much research has focused on the effects of question structure (e.g., open/closed) on children's recall, however less focus has been placed on the content of these questions. In this study we analysed forensic interviews conducted with children in New Zealand (n=24), to explore the kinds of information children are being asked for and what they are offering in their accounts. Interviewers asked for, and children provided many different categories of information in their accounts and rarely indicated any difficulty or tentativeness in their responses. We were unable to evaluate the accuracy of children’s information but suggest caution should be exercised by interviewers in asking for categories of information that may exceed children’s capabilities, given their tendency to guess, infer or be compliant to interviewer requests in the absence of memory, understanding or knowledge to do so.
The Clinical Anesthesia Effect of Remifentanil Combined with Propofol in Laparoscopic Cholecystectomy in the Elderly
Authors: Fan Li
Published: September 2023

Objective: To explore and analyze the effect of remifentanil combined with propofol for anesthesia in patients undergoing laparoscopic cholecystectomy, and to explore its clinical application value. Methods: A total of 64 patients who underwent laparoscopic cholecystectomy were selected and randomly divided into two groups, with 32 patients in each group. The anesthesia used in the control group was propofol combined with fentanyl, whereas the observation group was propofol combined with remifentanil and fentanyl. Medical staff routinely performed thyroidectomy on the patients after receiving anesthesia. After the treatment was completed, the researchers recorded the adverse reactions of the patients and the anesthesia effect during laparoscopic cholecystectomy and analyzed the anesthesia effect of the patients. Results: After the operation, the excellent and good rates of anesthesia in the observation group were significantly higher (P < 0.05). Pain in the observation group was significantly lower (P < 0.05). The clinical indicators after receiving anesthesia were significantly better in the observation group (P < 0.05). During the operation period, the two groups had different degrees of adverse reactions, while the incidence of adverse reactions in the observation group was relatively lower (P < 0.05). Conclusion: Patients in the observation group showed better anesthesia and lower pain levels during surgery, higher excellent and good rates of anesthesia, lower VAS scores, and better anesthesia indicators. Therefore, remifentanil-propofol combined anesthesia can be used as an effective anesthesia option in laparoscopic cholecystectomy, which improves the anesthesia effect during the operation and the postoperative pain control of patients and has clinical application value.

To explore the effective treatment of orthopedic trauma infection, the cases selected were 35 patients with orthopedic trauma infection. The study period was from January 2020 to December 2022. They were divided into the study group (n = 18) and the control group (n = 17) through the double-blind randomization of the medical record numbered envelopes. The patients in the control group were treated with conventional debridement and dressing change, and the patients in the study group were treated with negative pressure sealing drainage technology. The frequency of dressing changes, visual analogue scale (VAS) score, wound healing time, hospitalization time, and good wound healing rate were compared between the two groups. The number of dressing changes, VAS score, wound healing time, and hospitalization time in the study group were lower than those in the control group (P < 0.05), and the rate of good wound healing in the study group was higher than that in the control group (P < 0.05). Negative pressure sealing drainage technology for orthopedic trauma infection patients can decrease the number of dressing changes, reduce pain, accelerate the time for wound healing, shorten hospitalization time, and improve wound healing effect, which has the value of popularization and application.
