Phosphorylation of Rec8 cohesin complexes regulates mono-orientation of kinetochores in meiosis I
Authors: Liu Yu , Min Yu , Liu Yongxin , Watanabe Yoshinori
Published: March 2024

In meiosis I, unlike in mitosis, sister kinetochores are captured by microtubules emanating from the same spindle pole (mono-orientation) and centromeric cohesion mediated by cohesin is protected in the following anaphase I. The conserved meiosis-specific kinetochore protein meikin (Moa1 in fission yeast) associates with polo-like kinase: Plo1 and regulates both mono-orientation and cohesion protection. Although the phosphorylation of Rec8-S450 by Plo1 associated with Moa1 plays a key role in cohesion protection, how Moa1-Plo1 regulates mono-orientation remains elusive. Here, we identify Plo1 phosphorylation sites in the cohesin subunits, Rec8 and Psm3. The non-phosphorylatable mutations at these sites showed specific defects in mono-orientation. These results enabled the genetic dissection of meikin functions at the centromeres.

Exploring the Role of Nonviolent Intrapersonal Communication in Enhancing our Self-Concept for Evolution of Responsible Citizenship
Authors: Kundu Vedabhyas , Shah Munazah
Published: March 2024

In contemporary times, a large number of individuals- due to multitude of concerns and challenges- oen find themselves engaging in toxic or violent intrapersonal communication. ey have to face difficult situations, varieties of inner conflicts and suffer from stress. Besides, violent intrapersonal communication leads to a negative self-concept and lowering of self-esteem. It is within this background that introducing nonviolent intrapersonal communication- to be nurtured and practiced in our daily lives- becomes crucial. By practicing nonviolent intrapersonal communication, a toxic inner communication ecosystem is transformed into a healthy one. When elements of nonviolent intrapersonal communication- like self-compassion, loving kindness towards self, avoidance of being judgmental towards self- are assimilated, the negative self-concept changes into a positive one. is paper will precisely look at this dimension using open-ended self-reports of respondents who have been oriented towards practicing nonviolent intrapersonal communication. Further, the paper will gauge on how the positive self-concept, which evolves by the use of nonviolent intrapersonal communication, gives a direction toward altruistic action, an essential element of responsible citizenship. e overarching goal of the paper is to attempt to develop an intrinsic link between nonviolent intrapersonal communication and its role in the development of a positive self-concept which gives way to altruistic action.

Globally, pollinating insects face significant pressure, largely due to intensively managed agricultural systems. There has been considerable focus on the provision of resources for pollinators in agricultural landscapes, but without understanding how existing farmland habitats affect pollinators there is a risk these conservation actions could fail.
The aim of this study was to explore the relationships between the quantity, diversity, and quality of on-farm habitats with pollinator communities. To meet this aim, pollinator, floral and habitat features were assessed at twenty-nine sites, encompassing both livestock and crop systems, at a range of farming intensities, in two regions of Ireland.
Results showed that the three main taxonomic pollinator groups (hoverflies, social bees, and solitary bees) were inconsistent in their responses to habitat and environmental variables. Hoverflies were negatively associated with farms with increasing amounts of linear feature and fewer drainage ditches, whereas bumblebees were positively associated with crop farms and the number of grassy margins, drainage ditches and hedgerows at a site. Solitary bees were negatively associated with crop farms and positively associated with high floral species richness. At a species level, community analysis showed that within taxonomic groups, individual species responded differently to environmental variables.
This study demonstrates that different farm types and habitat features impact pollinator groups differently. One-size does not fit all, thus on-farm conservation actions should be designed with knowledge of taxon-specific responses to maximise benefits. The quantity and diversity of essential habitats are important along with the quality of those features in terms of their capacity to provide sufficient resources for pollinators.

Published: March 2024

The steering wheel is among the important components of a vehicle, through it having full control over its direction. It is made of a metal base covered with a polymeric material. To improve the look and feel of a steering wheel, usually it is covered by leather. Choosing the material for covering the steering wheel must be done responsibly, because depending on the material, it can generate a certain type of comfort when using the steering wheel. Thus, the current work aims to evaluate the durability and wear resistance of different types of leather coatings used in automotive steering wheels. A series of tests were performed on leather samples before and after exposing them to special conditions (high\low temperature, humidity, UV) like tensile strength and elongation, tear strength, tear load, surface softness, color fastness and flex resistance. All the tests were performed according to actual standards in ICPI accredited laboratory. The results of the experiment showed that the durability and wear resistance of the leather varied significantly depending on the type of coating. Overall, the study provides valuable insights into the characteristics of different types of leather and can help future research involved in developing more durable and long-lasting steering wheel cover leathers.

Published: March 2024

This research is important because it has a novel to stunting intervention through a family approach. The research also answers previous researchers' expectations regarding the scarcity of research on stunting with a family approach. This research is a cross-sectional study conducted in March-May 2023 using secondary data processed from the 2021 Family Data Collection (PK21) data which is then carried out with a descriptive analysis. Banten Province has a number of families at risk of stunting, one-third of the total families in the province. Namely, 2,658,505 families were recorded and 885,301 families at risk of stunting. In sequence the number of families at risk of stunting in regencies and cities in Banten Province from the largest to the smallest is Cilegon City 219,973 families, Serang City 143,187 families, Tangerang City 118,273 families, South Tangerang City 126,800 families, Pandeglang Regency 115,807 families, Lebak Regency 74,313 families, Serang District 52,204 families and Tangerang District 43,744 families. This study concludes that Serang City, South Tangerang City and Pandeglang Regency are 3 districts/cities that have data on families at risk of stunting exceeding families that are not at risk of stunting in these districts/cities. Lebak, Pandeglang and Serang Regencies which border the Indian Ocean have the dominant factor causing stunting from the sanitation aspect. This study concluded that three times the number of family assistance staff from families at risk of stunting is needed in the context of stunting eradication and stunting prevention in the future.

Published: March 2024

The majority of air conditioning systems, including both cooling and heating systems, consume a significant amount of electrical energy as a result of their high electrical consumption and prolonged periods of operation. The use of thermal insulation materials in the building can help conserve electrical energy used for room conditioning systems. Natural fibers are used as an alternative in the production of thermal insulation, which is commonly referred to as bio-insulators. The utilization of oil palm trunk (OPT) fiber as the primary material for thermal insulation shows promise. This study aims to determine the specific attributes of OPT fiberboard that make it suitable for use as a thermal bio-insulator. The features examined encompass physical, mechanical, thermal, and fire-resistant attributes. The OPT fiber underwent a treatment process involving boiling at a temperature of 80℃ for a duration of 30 minutes. The fiberboard is manufactured using epoxy adhesive and calcium carbonate additive, and then printed using the hand lay-up process and cold-compaction technique. The physical characteristics of fiberboard indicate that there is a direct relationship between its density and water absorption.  Testing revealed that fiberboard has a low thermal conductivity and high heat capacity value. By including calcium carbonate, the burning time of the fiberboard was tested and seen to decrease, indicating a delay in the fiberboard burning process, as evidenced by the extended flame suppression time. The density of OPT fiberboard varies between 0.48 and 0.70 gr/cm3. The absorbency of water is inversely related to its density. Water absorption capacity generally rises with decreased density. The obtained heat capacity value is 1.28-2.38 J⁄(g℃). The mechanical value ranges from 1.00 to 3.55 MPa. The incorporation of calcium carbonate significantly impacts the thermal and mechanical characteristics of the fiberboard. The produced OPT fiberboard satisfies the requirements for good thermal, physical, and mechanical characteristics, making it a suitable bio-insulation material for buildings.

Published: March 2024

Sinabung Volcano is located in the Karo Highlands, Karo Regency, North Sumatra, Indonesia, with a peak of 2460 meters above sea level. This volcano experienced an increase in volcanic activity in the April-October 2021 period, so it is necessary to analyse volcanic seismicity to determine the hypocenter distribution of the volcano. This study aims to determine the hypocenter distribution and classification of volcanic earthquake types based on seismogram recording data of Sinabung Volcano at four stations, namely LKW, BGR, MDD and SGR stations. The method used in this research is Geiger's method with adaptive damping (GAD) to determine the distribution of hypocenters. The results showed that the hypocenter distribution gathered below the crater centre with depths from 0.172 km to 7.139 km. The determination of the hypocenter distribution of volcanic earthquakes is expected to provide information on the depth of the earthquake to determine the movement of magma and the characteristics of events that occur during the pre-eruption process of Sinabung Volcano so that this data can be used for mitigation decision making when there is an increase in the activity of Sinabung Volcano.

Published: March 2024

The development of hard magnets today is progressing very rapidly. Developing hard magnets based on rare earth metals becomes a severe problem when the raw materials are not readily available. The chosen solution is to replace oxide-based permanent magnets with small amounts of rare earth metals substituted to improve their magnetic properties. This study synthesized a permanent magnet oxide based on barium hexaferrite doped with lanthanum and cerium atoms. In the synthesis of this material, a mechanical wet milling technique is used to obtain a single-phase permanent magnetic Ba1-β-γLaβCeγFe12O19 system with composition (β = 0 - 0.5 and γ = 0 - 0.1). The precursors are weighted according to their stoichiometric composition. Each mixed composition was milled by high energy milling (PW 1000 in the mixer/mill) at a milling speed of 1000 rpm using steel balls with an average diameter of 12 mm. Grinding conditions included a ball-to-powder weight ratio of 2:1, milling time 5 hours, then compacted with 7000 Psi pressure and sintered at 1200oC for 2 hours. The surface morphology and microstructure of the resulting sample particles were observed using scanning electron microscopy (SEM) with the SEM JEOL JED 305 brand. The characterization results show that the particles are hexagonally homogeneous in shape with particle sizes in the range of 1000-2000 nm for β = 0 and γ = 0 (without doping). In general, the four samples with varying concentrations of doping ions La3+ and Ce4+ showed homogeneous hexagonal structures but smaller particle sizes than pure barium hexaferrite.

Berdasarkan kuesioner yang disebarkan kepada 52 responden tenaga medis dari berbagai rumah sakit yang berada di Kota Mataram dan di luar Kota Mataram, melalui kuesioner tersebut ditarik kesimpulan bahwa lebih dari 50% responden mengaku memiliki kendala mengenai proses pengecekkan infus pada pasien secara manual, hal ini disebabkan oleh ketersediaan infus pada pasien tidak dapat dipastikan karena laju infus pada pasien berbeda-beda, sehingga saat infus pasien habis memiliki waktu berbeda dan dapat menyebabkan keterlambatan pergantian infus. Akibat yang diterima oleh pasien jika pergantian infus terlambat dapat menyebabkan pergumpalan darah di sekitar daerah pemasangan infus dan dapat beresiko fatal dikemudian hari. Oleh karena itu, penulis melakukan penelitian untuk merancang suatu sistem monitoring massa infus berbasis IoT menggunakan load cell dan vibration motor untuk notifikasi. Penelitian ini menggunakan sensor load cell, vibration motor, dan 7 segment dengan protokol komunikasi data MQTT dan website sebagai antarmuka sistem. Penelitian terbagi menjadi 3 tahap pengujian yaitu pengujian black box, pengujian kalibrasi Sensor Load Cell, pengujian notifikasi, dan pengujian tahap akhir. Dari pengujian yang dilakukan menghasilkan kalibrasi Sensor Load Cell berada pada nilai -1090 dan dibandingkan dengan nilai pada timbangan digital terbukti valid. Serta notifikasi dapat diterima oleh user ketika persentase kapasitas infus berada pada angka 10%.

BUM Desa Putri Nyale Kuta di Desa Kuta merupakan salah satu desa di Kawasan Ekonomi Khusus (KEK) Mandalika yang terletak di Desa Kuta. BUM Desa Putri Nyale Kuta sempat menggunakan sebuah aplikasi untuk mengelola keuangan berbasis desktop, namun penggunaanya masih sulit dipahami oleh pengelola BUM Desa. Selain itu aplikasinya hanya bisa di akses secara lokal di komputer. Untuk itu diperlukan sebuah aplikasi yang lebih mudah untuk digunakan dan dapat diakses di manapun oleh pengelola BUM Desa sebagai penunjang untuk mengelola keuangan. Penelitian ini akan merancang sebuah user interface (UI) dan user experience (UX) dari website yang digunakan untuk mengelola keuangan pada BUM Desa hingga tahap prototype hasil pengodean. Desain dirancang menggunakan metode design thinking yang terdiri dari 5 tahap yaitu emphatize, define, ideate, prototype dan test. Pengujian konsep dilakukan dengan menggunakan metode sequential monadic dan pengujian usabilitas menggunakan System Usability Scale (SUS) untuk dapat mengetahui keterjawaban masalah terhadap UI dan UX yang dirancang. Pengujian melibatkan sebanyak lima responden yang merupakan pengelola keuangan BUM Desa Putri Nyale Kuta. Hasil pengujian konsep menunjukkan bahwa konsep dinilai memiliki keunikan dan perbandingan yang cukup baru, sangat menarik dan disukai, sangat berguna, sangat dipercaya, serta sangat relevan. Hasil pengujian SUS mendapatkan skor 72,5 yang masuk ke dalam kategori “acceptable” dan “good”.

Hydroponics is an agricultural cultivation that uses water as a growing medium. One of the plants that can be cultivated hydroponically is the pakcoy plant. Pakcoy is a plant with an optimum water temperature range for its growth which is 15-30°C. The process of stabilizing the water temperature is important because the optimal temperature will make plant growth good. Currently, the process of monitoring and stabilizing water temperature is done manually and the process is carried out periodically so it is not easy to do. Therefore, the authors conducted a study to design an IoT-based intelligent thermostat for wicking hydroponic systems for pakcoy plants. The intelligent thermostat system consists of a DS18B20 water temperature sensor, a Peltier cooling system, and a water pump and uses the MQTT data communication protocol. This research was conducted with 3 stages of testing, namely, black box testing, Peltier calibration testing, and the final stage of testing which is divided into 2, namely without using a website and using a website. The final stage of testing is carried out in the morning, afternoon, evening, night, and early morning with the results of the system testing working to stabilize the water temperature when there is a temperature change of up to 2°C and then stabilized periodically to a tolerance of 1°C. So it can be concluded that the system in this study belongs to the category of a good system and is feasible to use.

significance of mask usage, many individuals have not been using them correctly. In order to address this issue, a system for image processing was developed using Convolutional Neural Network (CNN) capable of identifying three categories: wearing masks correctly, wearing masks incorrectly, and not wearing a mask. The dataset employed consists of 500 images for each category. Additionally, a comparison between using RGB and grayscale images was conducted, revealing that the RGB-based image model achieved an accuracy of 94.78%, while the Grayscale image reached an accuracy of 89.22%. These results confirm the importance of color information in the mask-wearing position detection process. Through this research, it is hoped to contribute to raising public awareness regarding the significance of proper mask usage in the efforts against Covid-19.

Objective: To compare the retinal nerve fiber layer (RNFL) thickness between malnourished and healthy children using Spectral Domain Optical Coherence Tomography (SD-OCT). Study Design: Cross-sectional study. Setting: Department of Pediatrics, National Institute of Child Health and The Hashmani’s Hospital, Karachi, Pakistan. Period: January 2023 to June 2023. Material & Methods: Twenty-two malnourished children of either gender, aged between 5-12 years, with no ocular findings, and another 22 healthy children of either gender with relatively similar age, with no ocular findings were enrolled. Anthropometric measurements including height and weight were performed and Z-score were calculated. All participants underwent a comprehensive eye examination. The SD-OCT was employed to record thickness of the RNFL. Results: In a total of 44 children, there were 22 (50.0%) boys and 22 (50.0%) girls. The mean age was 9.30±2.93 years (ranging between 5 to 12 years). The mean BMI Z-score was -1.01±2.11. Intraocular pressure was significantly reduced in children with malnutrition (p<0.001). Children with malnutrition were having significantly decreased superonasal (110.27±19.26 vs. 125.32±17.49, p=0.010), and infernonasal (112.86±21.04 vs. 132.00±31.53, p=0.023) RNFL. Correlation of body mass index (BMI) Z-Scores with parameters of RNFL thickness showed a significantly positive relationship with global scores (p=0.031). Conclusion: Our study using SD-OCT revealed that malnourished children exhibited decreased thickness of RNFL compared to healthy children. Furthermore, there was a positive relationship between BMI Z-scores and global RNFL thickness scores.
