Dalam bangunan rumah tinggal, sistem struktural dinding bata terkekang (Confined Masonry Wall, CMW) sering digunakan untuk menghadapi beban gempa karena kemampuannya dalam menahan beban searah bidang dinding (in-plane). Penelitian ini bertujuan untuk menganalisis respons struktural CMW terhadap Gempa Pidie Jaya 2016 melalui pendekatan eksperimental dan pemodelan macro. Penelitian ini menggunakan perangkat lunak SeismoStruct untuk pemodelan CMW. Parameter pemodelan mencakup karakteristik material dan struktural, seperti modulus elastisitas, kuat luluh, kuat tekan, kuat tarik, serta panjang sendi plastis pada elemen kolom dan balok, juga karakteristik dinding pasangan bata. Pembebanan Non-linear Time History (NLTH) dilakukan dengan variasi Peak Ground Acceleration (PGA) 0,3g, 0,6g, 0,8g, dan 1,0g. Validasi menunjukkan error terendah pada PGA 0,3g (0,14%) dan tertinggi pada PGA 1,0g (3,87%). Hasil analisis menunjukkan perbedaan respons struktur pada variasi PGA dan arah gempa. Output analisis lebih fokus pada arah horizontal dengan deformasi maksimum terjadi pada PGA 1,0g (1,05908 mm) yang tergolong dalam batas Deformasi Elastis. Penelitian ini memberikan wawasan tentang respon struktural CMW terhadap Gempa Pidie Jaya 2016. Melalui pendekatan eksperimental dan pemodelan, CMW menunjukkan potensi untuk mengatasi gempa dengan tingkat keparahan yang sesuai.

Authors: Zurma Jihan Arifa , Huzaim Huzaim , Hasibuan Purwandy
Published: January 2024

Salah satu jenis profil baja yang cukup populer belakangan ini yaitu profil baja hollow. Baja hollow adalah salah satu jenis baja yang terdapat lubang kosong pada bagian tengahnya. Penggunaan baja hollow untuk komponen struktur pada bangunan masih sangat jarang ditemukan. Hal ini disebabkan karena ketebalan baja hollow yang sangat tipis jika dibandingkan dengan tulangan biasa dan terdapat rongga kosong yang mudah tertekuk jika diberikan beban. Untuk mengatasi hal tersebut, mortar digunakan sebagai pengisi rongga kosong pada baja hollow. Penelitian ini akan merencanakan sebuah inovasi dengan menempatkan rangka bidang baja hollow pada struktur bawah bangunan seperti pondasi. Oleh karena itu, diperlukan sebuah upaya untuk melindungi rangka bidang tersebut agar terhindar dari korosi yaitu dengan merancang suatu rangka bidang yang diselimuti oleh beton sehingga terbentuk struktur balok beton yang dikuatkan oleh rangka bidang baja hollow yang terisi mortar. Tujuan yang ingin dicapai pada penelitian ini adalah untuk mengetahui nilai kapasitas dan daktilitas balok beton yang diperkuat oleh rangka bidang baja hollow yang terisi mortar dengan variasi tinggi rangka. Penelitian ini  menguji 3 buah balok beton yang divariasikan berdasarkan ketinggian rangka yaitu 400 mm, 500 mm dan 600 mm. Setiap benda uji diberi nama RBT40, RBT50, dan RBT60. Hasil penelitian menunjukkan bahwa adanya pengaruh pemakaian beton yang menyelimuti rangka bidang terhadap nilai kapasitas dan daktilitas, dimana semakin tinggi rangka bidang maka kapasitas balok beton dalam menahan beban semakin baik namun pada nilai daktilitas menunjukkan hasil yang berbanding terbalik.

Nosology of Genetic Skeletal Disorders, Pakistan: An Updated review
Authors: Khan Mujahid , Umair Muhammad
Published: January 2024

Genetic skeletal disorders (GSDs) are heritably and clinically varied class of bone and cartilage anomalies, characterized by irregular growth/development of the skeleton. They are rare, but their cases may be upraised with endogamy as it increases homozygosity. Pakistan has highest rate (55-60%) of consanguinity, which is highly detrimental to health. Still, Pakistan has no reliable data (geographical prevalence, clinical and epidemiological data) associated with GSDs and other rare genetic disorders. Unfortunately, due to the lack of adequate clinical/diagnostic resources and genetic knowledge, the suspected cases of genetic disorders are misdiagnosed and hence mistreated, thus, casing psycho-socio-economic problems.
The present study reviewed current literature, published in several internet data-bases included the Nosology of Genetic Skeletal Disorders: (2023 Revision)" from Pakistan. GSDs such as Acromesomelic dysplasia, Mucopolysaccharidosis, Polydactyly, Synpolydactyly and Split hand/Split foot malformation were reported in several families and have a 55.04% of all the reported GSDs from Pakistan.
Till-date, in the literature 72 different mutated genes has been reported from Pakistani community. This review will help clinicians and researchers in understanding, diagnosis and management of GSDs and will offer a descriptive of approach to carry out fruitful molecular genetic research in genetically vulnerable and low resource regions. Moreover, it will also speed up the possible therapy development and may insist the stakeholders to establish a multi-level network to find a path towards the healthcare challenges of GSDs from Pakistan.

Published: January 2024

Dieser Beitrag beschäftigt sich mit möglichen suburbanen Erschließungsmöglichkeiten im suburbanen Raum am Beispiel des Gemeindeorts Kernen-Stetten. Ausgehend von der Annahme, dass der ÖPNV im suburbanen Bereich mit deutlich unattraktiveren Grundbedingungen zu kämpfen hat und viele Ausbaumaßnahmen zeit-intensiv sind, sollten für die Gemeinde verschiedene ÖPNV-Anbindungsmöglichkeiten aufgezeigt werden, mit denen mehr Leute auf den ÖPNV umsteigen könnten. Hierfür soll zunächst eine ÖPNV-Bestandaufnahme durchgeführt werden, sowie mit der Seilbahn, der Stadtbahn und der Taktverdichtung des Expressbus drei mögliche infrastrukturelle Erschließungsmöglichkeiten präsentiert werden, die anhand verschiedener verkehrsplanerischer Indikatoren vergleichend präsentiert werden. Ziel dieses Beitrags soll eine kritische Ausei-nandersetzung mit den verschiedenen Möglichkeiten sein, wie die Anbindungsqualität und die Abwicklung der Wege vom und zum Gemeindeteil Stetten bei jedem potenziellen ÖPNV-Projekt nachhaltig verbessert werden könnte, welche indirekt auch eine Maßnahme gegen die Luftverschmutzung in der Landeshauptstadt Stuttgart darstellen kann.
Understanding the Adiabatic Evolution of Surface States in Tetradymite Topological Insulators under Electrochemical Conditions
Authors: Weng Guorong , Laderer William , Alexandrova Anastassia N.
Published: January 2024

Nontrivial surface states in topological materials have emerged as exciting targets for surface chemistry research. In particular, topological insulators have been utilized as electrodes in electrocatalytic reactions. Herein, we investigate the robustness of topological surface states and band topology under electrochemical conditions, specifically in the presence of an electric double layer. First-principles band structure calculations are performed on the electrified (001) surfaces of Bi2Te3, Bi2Se3, and Sb2Te3 using an implicit electrolyte model. Our results demonstrate the adiabatic evolution of the surface states upon surface charging. Under oxidizing potentials, the surface states are shifted upward in energy, preserving the Dirac point on the surface and the band inversion in the bulk. Conversely, under reducing potentials, hybridization is observed between the surface and bulk states, suggesting a likely breakdown of topological protection. The position of the Fermi level, which dictates the working states in catalytic reactions, should ideally be confined within the bulk bandgap. This requirement defines a potential window for the effective application of topological electrocatalysis.

A method was developed that enables the magnesium chloride (MgCl2)-activated S-acetamidomethyl cysteine sulfoxide (Cys(Acm)(O)) to induce the sp2(C−H) sulfenylation of the indole ring of Trp residues. The reaction operates under mild acidic conditions using acetic acid or an ionic liquid in a highly Trp-selective manner to give the Trp-sulfenylated products. Other than Trp, all other proteinogenic amino acids are unreactive to the sulfenylation conditions. We demonstrated the successful application of this reaction to a variety of peptides, including lysozyme protein. Furthermore, we achieved the Trp-modification of a monoclonal antibody (trastuzumab®) by a MgCl2-mediated reaction in an acidic ionic liquid. The resulting modified antibody exhibited antibody performance comparable to the parent protein. The presence of an amide moiety in the Acm group contributes to the difference in chemical behavior between S-Acm and S-p-methoxybenzyl (MBzl)-protected cysteine sulfoxide. This is because the S-Acm sulfoxide is converted to S-chlorocysteine responsible for Trp-sulfenylation under less acidic conditions than those required for the reaction of S-MBzl sulfoxide. Based on this rationale, we prepared a linker possessing S-Acm and S-MBzl oxide moieties and subjected the linker to hetero dimerization of DNA-binding Myc and Max peptides containing a Trp handle. The one-pot/stepwise Cys-Trp conjugation between the linker and DNA-binding peptides allowed the generation of a heterodimeric Myc/Max DNA binder.

Authors: Nurullah Rabbani Golam Mustafa MD. , Nath Avishek , Hasan Emon Md Mehedi
Published: January 2024

This study aims to investigate the challenges and opportunities associated with the integration of Big Data Analytics (BDA) within Management Information Systems (MIS) in the context of Bangladesh, a developing economy with distinct characteristics. A mixed-methods approach was employed, combining survey data from 40 organizations and in-depth interviews with key informants to explore BDA implementation challenges and opportunities unique to Bangladesh. The findings reveal that organizations in Bangladesh encounter challenges related to limited technological infrastructure, data security and privacy concerns, skill shortages, and regulatory complexities. Despite these challenges, BDA offers significant opportunities, including economic and business growth, government support, local market understanding, and increased competitiveness. This study is limited by its focus on the Bangladeshi context and may not fully capture the diversity of challenges and opportunities in other developing economies. Future research should consider cross-cultural comparisons and sector-specific analyses. The insights generated by this research provide organizations in Bangladesh with a roadmap for navigating BDA implementation challenges while harnessing its potential for economic growth and market competitiveness. Policymakers and government bodies can use these findings to formulate policies that support BDA adoption and economic development. As organizations leverage BDA to understand local market dynamics and enhance customer experiences, there is potential for improved products and services that cater to the unique preferences of Bangladeshi consumers. This has implications for broader society in terms of enhanced consumer satisfaction. This study contributes to the literature by enriching our understanding of the complexities of BDA integration in developing economies. It highlights the need for tailored strategies, fosters innovation, and positions BDA as a catalyst for economic growth and competitiveness in Bangladesh. The research is limited to a sample of 40 organizations in Bangladesh, and the findings may not be fully generalizable to all industries and contexts within the country.

OPTIMIZATION OF QUANTITATIVE RESEARCH METHODS IN SOCIAL SCIENCES IN THE ERA OF BIG DATA
Authors: Song Yirui
Published: January 2024

As information technology continues to advance, the complexity of data is ever-increasing. Traditional quantitative research methods in the social sciences, such as basic visualization and traditional statistical models, are gradually becoming inadequate in meeting the demands of modern data analysis. Despite the challenges that big data presents, it also brings new opportunities – through its usage, the optimization of traditional methods can be achieved. More intricate graphing techniques such as mosaic plots, alluvial plots, slope charts, and area charts, alongside machine learning algorithms that are better adapted for big data analysis such as decision trees, random forests, and K-Means algorithm, are opening new avenues for quantitative analysis in social sciences. This will ultimately foster further development of the field by allowing new methods and ideas to emerge.

Authors: Hasan Emon Md Mehedi
Published: January 2024

Solar technology has gained significant attention as a promising renewable energy source to mitigate climate change and reduce dependence on fossil fuels. This study aimed to assess the awareness, knowledge, and perception of solar technology among the general population. A survey was conducted among a diverse sample of respondents, and data were collected on their awareness, knowledge, perceived benefits, barriers to adoption, and factors influencing acceptance of solar technology. The findings revealed that while a considerable proportion of respondents had some level of knowledge about solar technology, there is room for improvement in increasing awareness and knowledge. Media was the most common source of awareness, but other potential sources, such as education, friends, family, and community-based initiatives, can play a significant role. The benefits of solar technology were recognized, but barriers to adoption, including cost, availability, and lack of awareness, were identified. Socio-demographic factors, such as age, education, and income, were found to influence perception and use of solar technology. Based on the findings, collaborative efforts among media, educational institutions, government, NGOs, and communities should be made to increase awareness and knowledge about solar technology, particularly targeting segments of the population with lower knowledge levels. Additionally, measures such as financial incentives, subsidies, and maintenance services should be considered to address the barriers to adoption. The study underscores the importance of increasing awareness, knowledge, and favorable perceptions of solar technology to promote its wider adoption for a sustainable energy future.
