Authors: Hanif Fitra Nur
Published: May 2023

Counting is a material that is considered not easy for most elementary school students. Not only from the considerations that are considered challenging but also the influence of the teacher's teaching style which makes bored, and boring is also a problem. In this study, an educational game balloon shooter prime numbers were made. In game design, the Mamdani fuzzy algorithm is applied to calculate the jumrance of balloons with the input variables of remaining_balloon and remaining_time. The application of the Mamdani fuzzy algorithm is considered successful, as evidenced by the high percentage rate of appearance of all balloons, reaching 76.4%.
Tip Vortex Meandering Characteristics of a Model Helicopter Rotor with Different Tip Shapes
Authors: Uluocak Sinem , Percin Mustafa , Uzol Oguz
Published: May 2023

This paper presents the results of an experimental investigation regarding the tip vortex meandering characteristics for a model helicopter rotor with different blade tip shapes. Phase-locked particle image velocimetry measurements are performed at the rotor phase angles between 0 and 72° with 6° increments. The meandering characteristics are presented along the first and the second principal axes of the meandering motion, which are found using the principal component analysis method. For all blades, the results show that the vortex position scattering along the principal axes can be defined with a Gaussian distribution. The scatterings about the second principal axes have a better agreement with the Gaussian distribution, with a fit up to the 95th percentile of the data, than the first axes for all configurations. Streamwise variations of the standard deviation of the meandering motion along the principal axes and the meandering angle, which is the angle between the slipstream and the first principal axis, are analyzed, and a simple empirical meandering model as a function of wake age is proposed. The meandering angle decreases with the vortex age, so the first principal axis becomes more aligned with the slipstream direction ([Formula: see text]) from close to being perpendicular ([Formula: see text]) at the early wake ages.

Published: May 2023

Presenteeism, çalışanın iş yerinde bulunmasına karşın kişisel veya örgütsel nedenlerle ya da sağlık sorunlarına bağlı olarak üretkenliğinin düşmesi ve iş yerinde bulunsa da verimli çalışamaması durumu olarak tanımlanmaktadır. Kavram olarak presenteeismin tanımı başlarda uzun süre çalışanın sadece hasta olmasına rağmen işe gitmesinin getirebileceği riskler bazında değerlendirilmiştir. Ancak son 15 yılda bazı yazarlar presenteeism kavramının çerçevesinin daha geniş olması gerektiği fikrini ortaya atmışlardır. Tanımında çalışanın işte fiili olarak bulunmasına rağmen zihnen işte olmaması ya da olamaması olarak açıklanan presenteeismin hastalığa indirgenmesi, literatürde tartışma yaratmaktadır. Presenteeism görece yeni bir kavram olup örgütsel davranış ve örgütsel psikoloji alanlarında henüz tartışmaları devam etmektedir. Bu nedenle presenteeismin ve boyutlarının güncel yaklaşımlarla yeniden ifade edilmesi gerekliliğine ihtiyaç vardır. Öte yandan sağlık alanı açısından düşünüldüğünde sağlık çalışanının presenteeism davranışları içerisinde olmasının sağlığa has özellikler bakımından diğer işletmelerin çalışanlarına kıyasla daha büyük risk teşkil edebileceği düşünülmektedir. Böyle bir durumda alt ve orta düzey yöneticinin iyi bir tespit yöntemi uygulaması ve sorunu çözmede hassasiyet göstermesi gerekmektedir. Çünkü sağlıkta işlerin acil ve ertelenemez olduğu, hata, kuşku ve yanılgıya yer olmayan sağlık sektöründe presenteeismin sonuçları ayrı ve ciddi önem taşıyabilmektedir. Bu çalışmada bütünleştirici derleme türü kullanılarak geniş bir literatür taraması ile presenteeismin nedenleri sınıflandırılmakta, sonuçları bireysel ve örgütsel anlamda ele alınmakta, sağlık çalışanları açısından önemi açıklanmakta ve yapılan çalışmalar sonuçlarıyla birlikte değerlendirilerek boyutları tanımlanmaktadır.

Nuclear magnetic resonance (NMR) chemical shift calculation is a powerful tool for structural elucidation, and has been extensively employed in both synthetic and natural product chemistry. However, density functional theory (DFT) NMR chemical shift calculations are usually time-consuming, while fast data-driven methods often lack reliability, making it challenging to apply them to computationally intensive tasks. Herein, we have constructed a 54-layer deep graph convolutional network for 13C NMR chemical shift calculation, which achieved high accuracy with low time-cost, and performed competitively with DFT NMR chemical shift calculations on structure assignment benchmarks. Our model utilizes a semi-empirical method, GFN2-xTB, and is compatible with a broad variety of organic systems, including those composed of hundreds of atoms or elements ranging from H to Rn. We used this model to resolve the controversial J/K rings junction problem of maitotoxin, which is the largest whole molecule assigned by NMR calculation to date. This model has been developed into a user-friendly software, providing a useful tool for routinary rapid structure validation and assignation, as well as a new approach to elucidate the large structures that were previously unsuitable for NMR calculation.

SARS-CoV-2, the new coronavirus variant is a world-wide health crisis. Over spans of human history, preparations derived from natural products have always been recognized as a preliminary source of medications. Taking into account the SARS-CoV-2 main protease (Mpro) as the essential element of the viral cycle and as a main target, herein we highlight a computer-aided comprehensive virtual screening for a focused chemical list of 14 laulimalides marine macrolides against SARS-CoV-2 main protease (Mpro) using a set of integrated modern computational techniques including molecular docking (MDock), molecule dynamic simulations (MDS) and structure-activity relationships (SARs) as well. Indeed, computational studies had disclosed two promising macrolides [laulimalides LA4 (6) and LA18 (13)] based on their remarkable ligand-protein energy scores and relevant binding affinities with the SARS-CoV-2 (Mpro) pocket residues. Consequentially, the two compounds were further investigated thermodynamically though deciphering their MD simulations at 100 ns, where they showed noticeable stability within the accommodated (Mpro) pockets. Moreover, in-deep SARs studies suggested the crucial roles of the C-23 subistituted side chain and the C-20 methoxy as essential pharmacophoric structural features for activity. Such interesting outcomes are highly recommending further in vitro/vivo examinations regarding those marine macrolides and open a gate towards developing more effective antivirals drug leads.

Published: May 2023

The recently discovered I(III) reagent NO2-C6H4-I(OTf)2 is found to rapidly react with hydride sources, including HSiEt3 and relatively hydridic C-H precursors. This represents the first distinct reactions involving direct hydride abstraction by I(III). Direct C-F abstraction is also demonstrated, as well as oxidation of cyclic alkenes to aromatic rings, all representing new reactions for I(III) demonstrating the very high reactivity of NO2-C6H4-I(OTf)2.
Anisotropy-Driven Crystallization of Dimensionally Resolved Quasi-1D van der Waals Nanostructures
Authors: Cordova Dmitri , Chua Kenneth , Huynh Rebecca , Aoki Toshihiro , Arguilla Maxx
Published: May 2023

Unusual behavior in solids emerge from the complex interplay between crystalline order, composition, and dimensionality. In crystals comprising of weakly-bound one-dimensional (1D) or quasi-1D (q-1D) chains, properties such as charge density waves, topologically protected states, and indirect-to-direct band gap crossovers have been predicted to arise. However, the experimental demonstration of many of these nascent physics in 1D or q-1D van der Waals (vdW) crystals is obscured by the highly anisotropic bonding between the chains, stochasticity of top-down exfoliation, and lack of synthetic strategies to control bottom-up growth. Herein, we report the directed crystallization of a model q-1D vdW phase, Sb2S3, into dimensionally resolved nanostructures. We demonstrate the uncatalyzed growth of highly crystalline Sb2S3 nanowires, nanoribbons, and quasi-2D nanosheets with thicknesses in the range of 10 to 100 nm from the bottom-up crystallization of [Sb4S6]n chains. We found that dimensionally resolved nanostructures emerge from two distinct chemical vapor growth pathways defined by diverse covalent intra-chain and anisotropic vdW inter-chain interactions and precise precursor ratios. At sub-100 nm nanostructure thicknesses, we observe the hardening of phonon modes, blue-shifting of optical band gaps, and emergence of a new high-energy photoluminescence peak, suggesting a confinement-induced indirect-to-direct optical band gap crossover. The directional growth of weakly bound 1D ribbons or chains into well-resolved nanocrystalline morphologies provides opportunities to develop ordered nanostructures and hierarchical assemblies that are suitable for a wide range of optoelectronic and quantum devices.
Scanning transmission X-ray spectromicroscopy: a nanotool to probe hematite nanorods for solar water splitting
Authors: Stanescu Stefan , Stanescu Dana , Hitchcock Adam
Published: May 2023

We report a scanning transmission X-ray microscopy (STXM) study of hematite nanorods, prototypical photoanode used in solar water splitting. Hematite nanorods were obtained by hydrothermal growth from aqueous solutions using FeCl3 as precursor. Potentials for onset of water splitting are smaller using this synthesis method, compared to values reported for hematite photoanodes obtained by epitaxial growth. STXM revealed the presence of a hexahydrate iron chloride phase at the surface of the nanorods, which is linked to the low onset potential values. We detail the quantification approach that revealed the specific microstructure of individual hematite nanorods.

Published: May 2023

N-Heterocyclic scaffolds have generated significant interest among medicinal chemists. Among these potential heterocyclic drugs, benzimidazole and imidazopyridine scaffolds are the most prevalent. Over the past few decades, it has gained immense attention. Both are important classes of molecules owing to their wide spectrum of biological activities and clinical applications. Both are used in fashion design and the development of novel synthetic analogs for various therapeutic disorders. A wide variety of derivatives have been developed as potential anticancer, antimicrobial, antiviral, and anti-inflammatory agents in addition to other chemotherapeutic agents. The benzimidazole core is found in a natural system, displaying a wide range of pharmaceutical properties, and has gained significant attention in medicinal chemistry, as reported in several full articles and communications. Imidazopyridines are widely distributed in many pharmacologically important compounds, as shown by their frequent occurrence in a large number of marketed drug formulations and drug candidates, as well as in other fields such as material and organometallic chemistry. These scaffolds have been structurally characterized as ligands that can bind to different receptor sites for the discovery of various emerging drugs. They act as key pharmacophore motifs for the identification and optimization of lead structures to increase the medicinal chemistry toolbox. This review outlines the synthesis and medicinal significance of benzimidazoles and imidazopyridines for their development as lead molecules with improved therapeutic efficiency. Here, we cover the various designs used to obtain both heterocycles to establish a relationship between their combination and biological activities.
Metal-organic frameworks meet Uni-MOF: a transformer-based gas adsorption detector

Published: May 2023

Gas separation is crucial for industrial production and environmental protection, with metal-organic frameworks(MOFs) offering a promising solution due to their tunable structural properties and chemical compositions. Traditional simulation approaches, such as molecular dynamics, are complex and computationally demanding. Although feature engineering-based machine learning methods perform better, they are susceptible to overfitting because of limited labeled data. Furthermore, these methods are typically designed for single tasks, such as predicting gas adsorption capacity under specific conditions, which restricts the utilization of comprehensive datasets including all adsorption capacities. To address these challenges, we propose Uni-MOF, an innovative framework for large-scale, three-dimensional MOF representation learning, designed for universal multi-gas prediction. Specifically, Uni-MOF serves as a versatile "gas adsorption detector" for MOF materials, employing pure three-dimensional representations learned from over 631,000 collected MOF and COF structures. Our experimental results show that Uni-MOF can automatically extract structural representations and predict adsorption capacities under various operating conditions using a single model. For simulated data, Uni-MOF exhibits remarkably high predictive accuracy across all datasets. Impressively, the values predicted by Uni-MOF correspond with the outcomes of adsorption experiments. Furthermore, Uni-MOF demonstrates considerable potential for broad applicability in predicting a wide array of other properties.

The development of new powder feedstocks using nanoparticles (NPs) has the potential to enhance the functionality of as-built parts and overcome the limitations of current additive manufacturing (AM) techniques. This study investigated the impact of NP feedstock modification on the microstructure and functionality of MQP-S after suction casting. Two types of NPs, Ag, and ZrB2, were used, and their effects on grain size distribution and dendritic structure were evaluated. Ag NPs resulted in smaller, more uniform grain sizes and increased functionality, but only for loadings > 0.5 monolayers. ZrB2 resulted in uniformly distributed grain sizes at much lower mass loadings, with even more compact dendritic arms. However, no effect on functionality was observed. The results show that feedstock modification with low melting point metal NPs can improve the microstructure and magnetic properties of permanent magnets produced by AM and highlight the potential of using NPs to develop new powder feedstocks for AM. With this, it provides insights for future research on optimizing AM processes.

With the development of ortho C-H functionalization in Pd/NBE chemistry, the catalytic systems used are becoming increasingly complex. The increasingly complex catalytic systems may have created technical barri-ers for researchers in other fields to apply Pd/NBE chemical methods. This report describes the use of a simple Pd/NBE catalytic system to achieve ortho C-H oxylation and phosphonylation and other functionalization of iodobenzene through templated conversion reactions. The key point of this method is to explore the previous-ly unknown step of introducing dimethylamine in the ortho position of iodobenzene through C-H amination. Aryl dimethylamine is quickly converted to methyl quaternary ammonium salt precipitation, and methyl qua-ternary ammonium salt effectively avoids Hofmann elimination in the subsequent functionalization.
Silicon-based Solid-State Batteries: Electrochemistry and Mechanics to Guide Design and Operation

Published: May 2023

Solid-state batteries are promising alternatives to the incumbent lithium-ion technology however, they face a unique set of challenges that must be overcome to enable their widespread adoption. These challenges include solid-solid interfaces that are highly resistive, with slow kinetics, and a tendency to form interfacial voids leading to delamination which results in diminished cycle life. This modelling study probes the evolution of stresses at the solid electrolyte (SE) solid-solid interfaces, by linking the chemical and mechanical material properties to their electrochemical response, which can be used as a guide to optimise the design and manufacture of silicon (Si) based SSBs. A thin-film solid-state battery consisting of an amorphous Si negative electrode (NE) is studied, which exerts compressive stress on the SE, caused by the lithiation-induced expansion of the Si. By using a 2D chemo-mechanical model, continuum scale simulations are used to probe the effect of applied pressure and C-rate on the stress-strain response of the cell and their impacts on the overall cell capacity. A complex concentration gradient is generated within the Si electrode due to slow diffusion of Li through Si which leads to localised strains. To reduce the interfacial stress and strain at 100% SOC, operation at moderate C-rates with low applied pressure are desirable. Alternatively, the mechanical properties of the SE could be tailored to optimise cell performance. To reduce Si stress, a SE with a moderate Young’s modulus similar to that of lithium phosphorous oxynitride (~ 77 GPa) with a low yield strength comparable to sulfides (~ 0.67 GPa) should be selected. However, if the reduction in SE stress is of greater concern, then a compliant Young’s modulus (~ 29 GPa) with a moderate yield strength (1-3 GPa) should be targeted. This study emphasises the need for SE material selection and to consider other cell components in order to optimise the performance of thin film solid-state batteries.

Published: May 2023

Purpose: The study aims to examine the role of Sustainable Entrepreneurship through the lens of Triple Bottom Line (TBL) with intervention of environment dimensions in Indian MSMEs context.
 
Theoretical framework: Sustainability has become the most important concern in today’s world due to the changes in the climate and environment deterioration. The TBL approach includes the people, planet and profit perspective; environment dimensions include the green and non-green initiatives that would help entrepreneurs to achieve their sustainable goals.
 
Design/methodology/approach: The quantitative research design is adopted to collect 107 entrepreneurs’ data from Delhi NCR using purposive sampling. The study examines the relationship among Sustainable Entrepreneurs (profit, planet and people) and environmental dimensions (green and non-green initiative) using SPSS and Hayes PROCESS.
 
Findings: The study concludes that there exists a correlation between people and planet; people and non-green initiatives; planet and profit; planet and non-green initiatives; and lastly green initiatives and non-green initiatives. In addition, non-green initiative mediates the relationship between people and planet. However, planet is correlated with only profit.
 
Research, Practical & Social implications: The research discusses various approaches for MSME to endeavour sustainability with the help of environment dimensions. The appropriate practice of adopting such sustainable approaches will eventually drive enterprises towards profit, thus becoming sustainable entrepreneurs.

Exploring Moral Hazard and Adverse Selection in Profit Sharing Contract
Authors: Salman Kautsar Riza
Published: May 2023

Purpose:  The aim of this study is to review relevant articles on the problem of adverse selection and moral hazard in profit-sharing contracts in Islamic Banks. Adverse selection and moral hazard problems are problems that occur in profit-sharing contracts, so they impact the low porti on of this contract financing compared to margin-based and fee-based contracts.
 
Theoretical framework:    The profit sharing contract in an Islamic bank has two potential problems, namely adverse selection and moral hazard that arise due to asymmetric information. Asymmetric information can occur due to limited information owned by Islamic banks as owners of funds (shahibul maal) regarding the business to be run by customers (mudharib). This asymmetric information mainly causes the agency problem. If an agent is negligent in making decisions with negative consequences and does not want to take responsibility for his actions, this can be classified as a moral hazard. Moral hazard can be in the form of self-interest, side effects, fraud, opportunism, and the behaviour of agents who commit willful mistakes, negligence and breach of contract. Meanwhile, adverse selection arises when the principal cannot observe the agent's characteristics because of asymmetric information before the contract is signed.
 
Design/methodology/approach:  The study uses a qualitative approach by reviewing previous articles relevant to the discussion. The study is aligned with the practices that occur in profit-sharing contracts. Furthermore, discussions are deepened through forum group discussions with experts and practitioners in Islamic banks.
 
Findings:  The results show that the conflicts in profit-sharing contracts include principal-agent conflicts and principal-principal conflicts due to adverse selection and moral hazards. The study results reveal that signalling and screening measures can be applied to overcome adverse selection problems while monitoring actions and switching to debt contracts can overcome moral hazard problems.
 
Research, Practical & Social implication:  The study has implications for Islamic banks to draw up a clear and complete profit-sharing contract with the mudharib to reduce the moral hazard committed by the mudharib. In this case, Islamic banks can also ask the mudharib to submit comprehensive financial reports regarding their financial performance. Islamic banks must also pay attention to signalling and screening efforts to prevent adverse selection.
 
Originality/value:  The value of the study provides a new literacy regarding the potential for agency conflict in the form of moral hazard and adverse selection that will be faced by Islamic banks when applying profit-sharing contracts with other parties as managers (mudharib).

Theoretical Framework: The existing literature has failed to address the gamut of legal, regulatory, and declarations (particularly Principle 10 of Rio 1992) and administrative frameworks for environmental protection and governance in Nigeria. These appeared to be a farce, hence the refusal to integrate the public and stakeholders’ opinions in environmental management that may conflict with official government policy.
 
Design/Methodology/Approach: The doctrinal method of analysis was adopted. It was based on current materials and drew on contrasting views of learned authors and scholars, as well as various legislative sources. Data was obtained using texts, articles, journals, case law, electronic sources, legislation, and other policy documents.
 
Findings: The results shows how the present legal and regulatory framework for the protection of the environment in Nigeria contradicts the concept of improved public participation.
 
Research, Practical & Social implications: The study suggest the development of an effective legislative framework that incorporates the guiding principles of global public participation initiatives for environmental sustainability.
 
Originality/Value: The value of the study reveals the global significance and the potential of public participation to improve the sustainability of the environment in Nigeria are essential to advancing the status of Principle 10 of the Rio Declaration as an emergent customary international law.

Herbal Rujak Soup Accelerates Uterine Involution On Postpartum Mothers
Authors: Mariati Mariati , Mizawati Afrina , Yorenza Ferly
Published: May 2023

According to the World Health Organization (WHO) in 2021, the highest mothersâ€™ mortality rate cases occurred in Africa with 525 deaths per 100,000 live births and the lowest was in Europe with 13 deaths per 100,000 live births. The most common cause of mothers mortality rate in Indonesia in 2019 was caused by several cases such as bleeding (30.32%). Uterine atony occurs due to failure of uterine contractions to control bleeding after delivery, causing uterine subinvolution. This process is known as uterine involution. The herbal composition of rujak soup is useful for preventing blood clots due to a compound called gingerol in ginger. The type of research used in this study was a quasi-experiment with a two-group post-test design. The population in this study was postpartum mothers from the first day to the tenth day of postpartum at PMB F Bengkulu City as many as 117 people with a sample of 30 respondents. The statistical test used was the Independent T-test. The results of this study indicate that the average acceleration of uterine involution on the seventh day is known that in the herbal soup rujak group is 4.73 and the uterine involution acceleration in the palm juice group is 5.40 with a mean difference between the herbal kuah rujak group and the date palm juice group. 0.67. There was an effect between the group of herbal ingredients of rujak sauce and the palm juice group on the TFU on day 7 with a p value = 0.038 and a mean difference of 0.67. This proves that the herbal rujak soup accelerates uterine involution more. It is hoped that the PMB of the Telaga Dewa Working Area will continue to promote complementary medicine with herbal ingredients to reduce the use of chemical drugs and help deal with problems during the postpartum period

Published: May 2023

The prevalence of overweight and obesity among children has become a global epidemic. The causes of obesity are multifactorial. Changes in lifestyle that lead to westernization and sedentary result in changes in eating patterns in children. The objective of this study was to determine the differences in maternal nutritional knowledge before and after counseling on balanced nutrition using e-booklets and their correlation to the consumption level of elementary school children who experience excess nutrition. The research design used was a pre-experimental one-group pretest-posttest design. A sample of 31 mothers and children who are experiencing excess nutrition from SDN 1 and 2 Sambirejo, Trenggalek regency was selected by purposive sampling. Data analysis employed the Paired Sample T-Test and Chi-Square test. There was an increase in the average score of mothers' knowledge from 69.03 to 77.41 with a p-value = 0.003 with ï¡ = 0.05. However, there was no correlation between a mother's knowledge and intake of energy, carbohydrates, protein, and fat. Nutrition counseling using e-booklet media can increase mothers' knowledge but it is not related to the intake of elementary school children who have more nutrition

The literature review method used a systematic mapping study design. Literature sources were obtained from the Google Scholar, Pubmed, and Proquest databases with 6 years of publication. The literature collection strategy using PEOS was then selected to produce 10 articles that matched the research criteria. Of 10 articles that examined the type of hormonal family planning (KB) that were mostly used were 3 articles with injectable KB, 2 articles on pill KB, 2 articles on KB implants, and 3 articles that did not mention the type. There were 3 articles describe that both <1 year and >1 year duration of the usage can cause vaginal discharge. There were 7 articles with analytical tests, 4 articles (57%) stated that there was a relation between the use of hormonal contraceptive methods and the occurrence of vaginal discharge, while 3 articles (43%) stated that there was no relation between the use of hormonal contraceptive methods and the occurrence of vaginal discharge. There were 3 articles that did a descriptive analysis, it was found that contraceptive users who experienced vaginal discharge were more than 35%. The use of hormonal contraception can cause physiological vaginal discharge since the hormones progesterone and estrogen change the flora and pH of the vagina, besides that vaginal discharge occurs because personal hygiene is not correct
Pro-forma Financial Statements of Technology-growth Company

To secure technological and industrial competitiveness, the KOSDAQ market is implementing a technology-growth listing system. In general, such listed companies have been recognized for their technological prowess at the time of listing, but there are few cases where the technology has been commercialized or realized. Nevertheless, the largest shareholder sold their shares after the lock-up period using the listing system to obtain capital gain. A company that utilizes the listing system for the purpose of acquiring such private gain may overestimate the pro-forma profit and loss to evaluate the company value higher than that of a company that did not sell its shares. Therefore, we verified whether the technology-growth listed companies, in which the largest shareholder sold their shares after the lock-up period, overestimate the pro-forma profit and loss compared to those that did not. The analysis revealed that the technology-growth listed companies in which the largest shareholder sold their shares after the lock-up period overestimated the pro-forma net income for the first year compared to the companies that did not.
Do Employees Have Information on Firm’s Future Performance? Evidence from SEO and ESOP

Published: May 2023

Using a sample of 576 equity right offerings announced between 2006 and 2015, this study analyzes the wealth effects of the discretionary or no allocation of new shares to Employee Stock Ownership Plan (ESOP) and the relationship between ESOP subscription rates and the long-run performance. The major results are as follows. First, for KOSPI firms that have obligation to allocate new shares to ESOP, those that do not allocate new shares have more negative announcement effects and long-run performance than those that do. Similarly, for KOSDAQ firms that have the discretion to allocate new shares to ESOP, those that allocate have less negative announcement effects and long-run performance than those that do not. Second, the significant positive relationship between ESOP subscription rates and long-run performance means that employees have significant information on the firms’ future prospects. Third, news on the large number of shares unsubscribed by ESOP provide negative information to the market. Firms in the top quartile of ESOP subscription rates outperform those in the bottom quartile by 27.54% in the year after purchase. Overall, ESOP members’ decisions regarding allocation and subscription provide valuable information on firm’s future performance.

Thermal buckling analysis of laminated plates with variable angle fiber orientation
Authors: BARAN Fatih , BALKAN Demet
Published: May 2023

The thermal buckling response of square plates with variable angle tows under simply supported conditions is modeled numerically. The path of variable angle tow is modeled as a function of lateral location. The classical lamination theory utilizes fiber paths to calculate thermal loads and stiffness matrices. Using Kirchhoff plate theory and finite element theory, the global material stiffness matrix and the global geometric stiffness matrix of the plate under thermal buckling loads are obtained. By using these matrices, eigenvalues or critical buckling temperature is obtained and the buckling response of the plate is examined. The theoretical results are validated by studies in the literature and finite element models. It has been seen even in an unoptimized span of a sample composite material, variable angle tows (VATs) were 8,60% more resistant to thermal buckling than common composite lay-ups.

Nose rings have through the ages been worn not just in India but all over the world. The reasons for wearing nose rings are varied which often takes ritualistic meanings. Some aboriginal tribes used bone or boar tusks to appear fiercer to their enemies. In tribal societies nose rings can assume amulet function to prevent evil spirits from entering the body. Nose is one of the most visible parts of the face. Nose ornaments greatly enhance and brighten the individual appearance. Therefore, a lot of attention and traditional significance has been attached to their designs. In India, the tradition of nose rings can be a rich source of cultural history of communities. The present study analyzes a few regional traditions pertaining to the practice of wearing nose rings. Nose rings have been selected to represent east, west, north, south, and central regions of India. The nose rings have been documented to highlight their historical and cultural significance and not just their decorative function. The focus of the study is to showcase unique illustrations through carefully selected nose ornaments worn in eight different states of India from the collection of the Amrapali Museum.
