In this study, indices and ratio calculations were performed using osteometric measurements of the long bones (humerus, radius, femur, tibia) of the thoracic and pelvic limbs in domestic cats. For this purpose, the bones of a total of 55 adult animals, comprising 33 males and 22 females, were used. Sexual differences were observed in osteometric measurements at a level of significance of p < 0.05, while no gender-related differences were observed in index values. The intermembral and humerofemoral index values were determined to be 89.83 +/- 3.22 and 94.42 +/- 5.46, respectively, while the brachial and crural index values were determined to be 96.65 +/- 3.54 and 106.55 +/- 6.63, respectively. The intermembral and humerofemoral indices obtained showed that the pelvic limbs of domestic cats were longer than the thoracic limbs. In domestic cats, both the thoracic and pelvic limbs had different activities in hunting, movement, and habitat strategies. A low brachial index indicated hunting manipulation and climbing movements requiring strength, while a high crural index and low intermembral index supported jumping and agility capacities. The data obtained were believed to serve as a reference for veterinary practice and zooarchaeological approaches, in addition to understanding the habitat strategy of domestic cats in urban life.

Penelitian ini bertujuan untuk menganalisis dan merancang ulang (redesain) bangunan Masjid Sabilal Muttaqin di Batam dengan pendekatan arsitektur postmodern, guna menciptakan ruang ibadah yang lebih fungsional, estetis, serta kontekstual terhadap kebutuhan masyarakat modern. Masjid sebagai ruang publik religius memiliki peran penting, tidak hanya sebagai tempat beribadah, tetapi juga sebagai pusat aktivitas sosial, edukatif, dan kultural yang memperkuat nilai-nilai kebersamaan. Permasalahan utama pada bangunan eksisting meliputi desain arsitektur yang monoton, sirkulasi udara yang kurang optimal akibat penggunaan jendela mati, serta akses masuk yang membingungkan antara area laki-laki dan perempuan. Penelitian ini menggunakan metode kualitatif deskriptif dengan teknik pengumpulan data melalui observasi lapangan, wawancara dengan pengurus masjid, serta analisis elemen desain berdasarkan aspek tata ruang, pencahayaan alami, penghawaan, dan estetika visual bangunan. Penerapan konsep postmodern dilakukan melalui prinsip eklektisisme, yaitu penggabungan unsur arsitektur klasik, modern, dan tradisional Melayu yang diekspresikan dalam bentuk komposisi warna, ornamen geometris, serta rancangan atap berlapis yang dinamis. Hasil perancangan menunjukkan bahwa penerapan gaya postmodern mampu memperkuat identitas visual masjid, meningkatkan kenyamanan termal dan sirkulasi ruang, serta menciptakan pengalaman ruang ibadah yang lebih inklusif, harmonis, dan berkarakter lokal. Temuan ini menegaskan bahwa pendekatan arsitektur postmodern merupakan strategi desain yang relevan bagi revitalisasi bangunan keagamaan di era kontemporer tanpa menghilangkan nilai-nilai spiritual dan budaya lokal.

In the Khurmala field, Kurdistan, a challenging water injection well required the cementing of a 7" liner while managing pre-existing formation losses. The primary objectives were to prevent further losses during cementing and ensure long-term zonal isolation, given the cement’s continuous exposure to bottom-hole pressures of 3000 psi during water injectivity post-completion. A novel ultra-lightweight (ULW) flexible cement slurry with a density of 9.5 ppg was developed to maintain equivalent circulating density (ECD) below the fracture point. The slurry was designed to provide improved mechanical properties for sustained zonal isolation under high-pressure conditions. To meet the challenges of cementing a 7" liner in the Khurmala field’s loss-prone formation, a 9.5 ppg ULW flexible cement slurry was developed. The slurry was designed to maintain the ECD below the formation’s fracture gradient, preventing losses. Mechanical properties, including Young's modulus and Poisson’s ratio, were optimized using Cement Stress Analysis software and extensive lab working to ensure flexibility, minimize micro-annuli, and withstand high injection pressures. The slurry blend was engineered for homogenous particle distribution to achieve a compressive strength of 2000 psi, ensuring consistent mechanical performance. A spacer with bridging LCM was also designed to mitigate losses. Extensive laboratory testing was performed under simulated downhole conditions, confirming its ability to maintain zonal isolation and structural integrity under continuous high-pressure exposure. The cement mixing and pumping operations were carried out as planned, with no losses encountered during the job. Post-job cement bond log (CBL) results demonstrated exceptional zonal isolation and bond quality. The cement successfully maintained its integrity under continuous exposure of 3000 psi, confirming the effectiveness of the design and the field application of the ULW flexible cement slurry. The Ultra-light weight slurry and improved mechanical properties ensured safe cement placement without inducing losses and ultimately provided long-term well integrity. The key novelty of this work is the development and field application of a 9.5 ppg ultra-lightweight flexible cement slurry designed for long-term zonal isolation in water injection wells. The slurry’s mechanical properties were tailored to withstand high-pressure conditions while ensuring long-term durability over extended time, even when exposed to compression, traction, and potential creation of micro-annuli. The approach provided an innovative solution to the challenges of cementing in weak formation, delivering both immediate operational success and sustained well integrity.

The main challenge addressed by this project is population ageing, a pressing issue for public policies in both Spain and Portugal. This phenomenon is particularly prominent in the regions involved in the project (EuroACE: Extremadura, Central Portugal, and Alentejo), which share common characteristics: low population density and a high rate of ageing. Thus, the project tackles shared territorial challenges in the Spain–Portugal cross-border area. Objectives: The primary objective of the project is to improve the quality of life of older adults by promoting autonomy using innovative technologies and cross-border cooperation. Methods: The promotion of physical activity, cognitive and socio-emotional stimulation, as well as the use of Information and Communication Technologies—such as robotics, serious games, and brain-computer interfaces—will be the main tools developed throughout the project. Through the development and implementation of these solutions and the application of technical knowledge, the cross-border cooperation is expected to contribute to addressing the demographic challenge of an ageing population. Results: The project is expected to have a positive impact on the EuroACE region, involving around 200 professionals in the implementation of the developed solutions with over 1,000 older adults. Through the project’s beneficiary partners, the results are also expected to impact over 50 institutions and companies in the business ecosystem. Conclusion: The EuroAGE+ Network will be essential in fostering research and innovation in the field of health and healthy ageing, improving quality of life and extending the healthy life expectancy of the population.

Kesadaran siswa dalam menjaga keamanan data, menerapkan etika digital, dan memanfaatkan teknologi secara produktif masih rendah, sehingga berpotensi menimbulkan risiko penyalahgunaan teknologi dan perilaku digital yang tidak tepat. Faktor-faktor yang mempengaruhi rendahnya literasi digital siswa meliputi kurangnya pengetahuan dan keterampilan digital, rendahnya kesadaran dan disiplin, keterbatasan dukungan guru dan akses teknologi, serta materi pembelajaran yang kurang interaktif. Pengabdian ini bertujuan untuk mengukur tingkat literasi digital siswa, mengidentifikasi faktor-faktor yang mempengaruhi, serta merancang dan melaksanakan program pelatihan literasi digital yang efektif bagi siswa SMK. Metode yang diterapkan mencakup penyampaian materi interaktif, tugas kreatif berupa pembuatan video ajakan atau iklan digital, serta evaluasi kuantitatif dan kualitatif melalui pre-test, post-test, observasi, dan diskusi kelompok. Hasil pelatihan menunjukkan peningkatan rata-rata skor pre-test dari 2,86 menjadi 4,46, atau sebesar 64,06%, serta perubahan sikap positif peserta. Temuan ini menegaskan bahwa pelatihan literasi digital yang terstruktur penting untuk meningkatkan pengetahuan, keterampilan, dan sikap bijak siswa SMK.
