Key Points

Women are under-represented in high-impact nephrology trials.

Trends remain consistent over the past 20 years and on the basis of target condition.

Addressing the imbalanced enrollment of women in trials could improve disparities in care and outcomes of kidney disease.

Background

Gender disparities in the incidence and complications of kidney diseases are well described. However, analysis to elucidate gender disparities in enrollment in nephrology randomized clinical trials (RCTs) has not been performed.

Methods

We performed a systematic review and meta-analysis of high-impact nephrology RCTs published between 2000 and 2021. We included RCTs enrolling participants aged 18 years and older in the following categories: (1) CKD, (2) AKI, (3) GN, (4) maintenance dialysis, and (5) kidney transplantation. We summarized trial characteristics according to reporting and enrollment of participants, enrollment site, publication year, trial category, and intervention type. Outcomes of interest include the proportion of enrolled male and female participants overall and according to trial category. In addition, we compared enrollment trends in the United States and globally to estimates of kidney disease prevalence.

Results

Most qualifying trials (373/380, 98%) reported the distribution of male and female participants. Enrollment was imbalanced overall with male participants accounting for 62% (n=215,850) of the enrolled participants and female participants for just 38% (n=133,082). Male participants formed most of trial cohorts in AKI (65%), CKD (62%), dialysis (55%), and transplant trials (65%), whereas women were majority enrollees in GN trials (61%). CKD trials under-represented women in both US trials and worldwide.

Conclusions

Women are under-represented in high-impact nephrology trials with the exception of GN trials. This imbalance may contribute to disparities in outcomes and gaps in the care of women with kidney disease.

Authors: YILDIRIM Salih Taner , YILMAZOĞLU Arif
Published: October 2023

In this study, the performance of colemanite, which is a valuable boron waste, and recycled cathode ray tube glass (CRT) in the cement mortar was examined by experimentally. Colemanite waste (CW) and CRT were replaced with cement and aggregate and used as mineral additives, and their effect on the physical and mechanical properties (PP and MP) of mortar was investigated. In addition to the reference sample that didn’t contain CW or CRT, seven more samples were used. In these samples, cement was used at a rate of 2.5% along with CW, and the aggregate was replaced with CRT at the rates of 10%, 20%, and 30%, and with the combination of CW and CRT. The workability, unit weight, and water absorption, compressive strength (CS), flexural strength (FS), and abrasion resistance properties of the mortars were compared. As a result of this study, it has been observed that the use of waste materials can make positive contributions to some of the PP and MP of the mortar. Thus, the goal of both improving the properties of the mortar and making it affordable by using waste materials were achieved.

Method for Coherent Compensation of Side Lobes of the Spectrum of Interfering Reflections in the Problem of Detecting Low-Speed and Inconspicuous Objects
Authors: Heister S. R. , Kirychenka V. V.
Published: October 2023

The detection of low-speed objects is a challenging task. The small radar cross-section of low-speed objects varying from one-thousandths to one-tens of a square meter practically excludes a successful detection of such objects against intense clutter from static objects by existing methods. In this work we present a method of coherent compensation of clutter from static objects in the sidelobes of the spectrum. The method provides successful detection of low-speed and low-visibility objects with reflective characteristics that create signals with power comparable to the power of spectral sidelobes of the clutter. The method is based on the representation of the side lobes of the spectrum of interfering reflections not in the form of noise, which determines the limiting level of “background whitening”, but in the form of a coherent spectral structure, amenable to further compensation. The proposed method must be especially effective in complicated situations such as when detecting signals reflected from low-speed and low-visibility objects (e.g., quadcopters) versus intensive clutter reflections from metal structures and buildings.

Authors: Shofiatul Khulqi Salwa , Eva Novita Restu Cut , Sucipto Imam
Published: October 2023

The importance of family in Islam is widely recognized, as it serves as the foundation for the construction of strong, resilient, harmonious, and happy societies. The establishment of a peaceful and cohesive society is intricately linked to the well-being of each family unit, as families are regarded as the epitome of a nation. To foster harmonious families, the adherence to appropriate processes and procedures in line with Islamic law and local customs is crucial. The dynamics and evolution of social traditions and customs in the context of premarital life exhibit diverse styles. For instance, the engagement traditions observed in various communities such as Seserahan in Java, Peningset or Ngemblok in Sunda, Merisik in Riau, Marhusip in Batak, Maminang in Minangkabau, Mapettuada in Bugis, and many others, exemplify the distinct premarital proposal customs prevalent in society. Khitbah refers to the formal request made by a man to a woman, or vice versa, expressing the intention to marry. It can be done directly or through intermediaries, in accordance with the provisions of Sharia. The Quranic evidence for Khitbah can be found in Surah Al-Baqarah (Chapter 2), Verse 235. Additionally, various hadiths discuss Khitbah, with one narrated by Abu Daud emphasizing the importance of motivating factors when proposing marriage.

Authors: Setiawati Nurul Sri , Sunra La , Sakkir Geminastiti
Published: October 2023

The purpose of this research is to explore the strategies used by English teachers in implementing learning during online classes. This research is qualitative research with a case study approach through interviews. The participants in this study were 2 English teachers from Makassar National Vocational School. The data in this study were obtained through 3 parts of interviews with a total of ten questions. The findings show that the strategies used by English teachers in implementing learning during online classes are diagnostic assessment and discovery learning using several applications including WhatsApp, Zoom, Google Classroom, YouTube, Google Forms, and the Google search engine. Teachers used several other strategies involving peer tutoring, using school facilities, implementing synchronous online learning, and parental counseling to overcome challenges. Therefore, it is recommended for teachers to continue to use or apply a combination of strategies that they have implemented. In addition, because there are also several strategies discussed in this study, readers of this study, especially teachers, can also use other strategies and technologies to increase the variety of their learning activities. Finally, during the observation of the application of discovery learning, the teacher used it to recount text materials with a combination of writing and speaking projects. It has the potential to be used differently in different material focuses and skills. So, it is also suggested that future researchers be more specific with certain aspects of teaching English such as language skills, or certain materials to enrich data related to that field.

Authors: Sharma Advit
Published: October 2023

Attacks and anomalies are quiet common in today’s technological world. However it is important to identify these anomalies as soon as possible since these anomalies can cause various problem. Therefore anomaly detection plays a vital role in detecting these outliers. Anomaly detection detects suspicious activity which fundamentally falls outside of the respected pattern of behaviour. Anomaly detection aims at identifying the unpredicted and unexpected events in data streams which are commonly referred to as anomalous events. Therefore proposed modified linearity based grey swarm algorithm and hyperparameter optimization techniques for improving the performance of the proposed model. Hyperparameter optimization techniques implemented in the proposed model are genetic algorithm (GA), Grid Search and Random Search. Feature selection is implemented in the proposed model is modified linearity based grey swarm algorithm since it has the ability to reduce the convergence. In addition to modified linearity based grey swarm algorithm, modified objective function is employed in the proposed model as it has the capability to find solutions to problems which are difficult to solve. Finally the performance of the proposed model is evaluated and assessed using various performance metrics such as accuracy, recall, precision and F1 score. At last, proposed model is compared with the existing models and found that proposed model outperformed other existing models.
Moving Target Defense Approach for Secure Relay Selection in Vehicular Networks

Published: October 2023

Ensuring the security and reliability of cooperative vehicle-to-vehicle (V2V) communications is an extremely challenging task, due to the dynamic nature of vehicular networks as well as the delay-sensitive wireless medium. The moving target defense (MTD) paradigm has been proposed to overcome the challenges of conventional solutions, based on static network services and configurations. Specifically, the MTD approach involves the dynamic altering of the network configurations to improve resilience to cyberattacks. Nevertheless, the current MTD solution for cooperative networks has several limitations, such as they are not well-suited for highly dynamic environments; they require high synchronization modules that are resource-intensive and difficult to implement; and finally, they rely heavily on the attack-defense models, which may not always be accurate or comprehensive to use. In this paper, we propose an intelligent spatiotemporal diversification MTD scheme to defend against eavesdropping attacks in cooperative V2V networks. Specifically, we design benign random data injection patterns to meet the security and reliability requirements of the vehicular network. Our methodology involves modeling the configuration of vehicular relays and data injection patterns as a Markov decision process, followed by applying deep reinforcement learning to determine the optimal configuration. We then iteratively evaluate the intercept probability and the percentage of transmitted real data for each configuration until convergence is achieved. In order to optimize the security-real data percentage (S-RDP), we developed a two-agent framework, namely MTD-DQN-RSS & MTD-DQN-RSS-RDP. The first agent, MTD-DQN-RSS, tries to minimize the intercept probability by injecting additional fake data, which in turn reduces the overall RDP, while the second agent, MTD-DQN-RSS-RDP, attempts to inject a sufficient amount of fake data to achieve a target S-RDP. Finally, extensive simulation results are conducted to demonstrate the effectiveness of our proposed solution where they improved the system security by almost 28% and 49%, respectively compared to the conventional relay selection approach.
Simulation of performance enhancement of heat exchanger with twisted tapes using ANSYS software
Authors: Fitrianto Taufik Ramadhan , Suhanan
Published: October 2023

Heat transfer effectiveness in a heat exchanger depends on the fluid flow through the exchanger. The heat transfer coefficient is directly proportional to the Nusselt number of the fluid flow. A higher Nusselt number indicates a greater heat transfer rate. The enhancement of heat transfer quality can be achieved by increasing the surface area for heat transfer, disrupting the boundary layer, and inducing swirl flow in the fluid. Twisted tape inserts are used in the heat exchanger to induce swirl flow. In this simulation, six types of inserts with a length of 2000 mm, width of 35 mm, and twist ratios of 2.5, 5.0, 7.5, 10, 12.5, and 15 were used. The mass flow rates of the fluid used were 0.4 kg/s, 0.6 kg/s, and 0.8 kg/s. The simulation was conducted using the ANSYS software with the Computational Fluid Dynamics (CFD) subprogram. The simulation results showed different flow patterns in each experiment. As the number of twists in the twisted tapes increased, the vortex flow in the fluid also increased. The highest performance was observed in the experiment using the twisted tape insert with 15 twists and a mass flow rate of 0.8 kg/s.
Analisis desain stamping die menggunakan FTI forming suite
Authors: Sutisna Nanang Ali , Afandi Vicky Gufron
Published: October 2023

Kajian ini dilakukan pada desain stamping die untuk salah satu komponen bodi mobil menggunakan perangkat lunak FTI Forming Suite. Pada umumnya, proses rancang bangun stamping die yang terdapat di perusahaan, diamati melibatkan tujuh hingga sepuluh percobaan sebelum mendapatkan die yang dapat diterima, yang akibatnya meningkatkan biaya die. Dengan menggunakan perangkat lunak, diharapkan jumlah percobaan berkurang karena desain dianalisis terlebih dahulu untuk mengidentifikasi cacat yang tidak diinginkan dalam proses stamping, seperti kerut, robek, dan springback. Tahapan kajian dimulai dengan membandingkan komponen hasil stamping dengan desainnya. Dengan menggunakan pemindai 3D, geometri komponen diperoleh dan dibandingkan dengan model CAD 3D asli untuk memeriksa penyimpangan komponen dari desain aslinya. Perbandingan antara komponen hasil stamping dengan desain asli menunjukkan ketidaksesuaian. Hal ini kemungkinan besar karena desain telah dimodifikasi untuk mencegah cacat stempel. Selanjutnya, desain asli disimulasikan dengan menerapkan gaya blank holder sebesar 109,7 kN. Simulasi pertama pada komponen desain asli menunjukkan bahwa thickness strain sebesar -14,4% dan memiliki kecenderungan kerutan yang kuat. Oleh karena itu, desain dimodifikasi, kemudian dilakukan simulasi lagi pada desain komponen yang dimodifikasi ini. Modifikasi terutama difokuskan pada radius sudut yang diperlukan, juga pada gaya blank holder menjadi 129,2 kN untuk mencegah kerutan dan mengurangi springback. Simulasi kedua menghasilkan formability yang baik, ditunjukkan dengan forming limit diagram (FLD), zona aman, dan springback yang lebih baik, meskipun thickness strain minimum meningkat menjadi -19,2%. Jadi, dengan menggunakan simulasi perangkat lunak, geometri cetakan yang benar dapat diperoleh sebelum pembuatan cetakan untuk menghindari biaya modifikasi die yang tidak perlu selama proses percobaan. Selain itu, jumlah percobaan dapat diminimalkan, sehingga lead time produksi stamping dies menjadi lebih singkat.

Conclusion: Arthroscopic reconstruction of ACL by quadrupled hamstring autograft fixed by biodegradable screws for both tibia and femur, leads good to excellent results in majority of the cases.
Friction Mechanics- A Review
Authors: Daniel Jibin joy , Amir Salman
Published: October 2023

Conventional wisdom suggests that resistance to sliding (RS) generated at the wire-bracket interface has a bearing on the force transmitted to the teeth. The relative importance of static and kinetic friction and also the effect of friction on anchorage has been a topic of debate. Lot of research work has been done to evaluate the various factors that affect friction and thus purportedly retards the rate of tooth movement. However, relevancy of these studies is questionable as the methodology used hardly simulates the oral conditions. Lately studies have concluded that more emphasis should be laid on binding and notching of archwires as these are considered to be the primary factors involved in retarding the tooth movement. This article reviews the various components involved in RS and the factors affecting friction. Further, research work should be carried out to provide cost effective alternatives aimed at reducing friction.

Introduction: Otosclerosis is an osteodystrophy of the otic capsula which is anatomically expressed by a stapedo-vestibular ankylosis. The objective of this work is to evaluate the audiometric result and to determine the predictive factors of functional failure. Materials and methods: we conducted a retrospective study about 21 ears operated for otosclerosis, within the department of otolaryngology and cervicofacial surgery CHU Mohammed VI Oujda over a period of 3 years (2016-2020). Epidemiological, clinical of patients and preoperative and postoperative audiometry at 12 months were analyzed. Surgical success was defined by a postoperative Rinne (RPO) ≤ 10db. Results: The mean age of the patients was 37,76 years. Female gender was predominant with a sex ratio of 2. The mean time to consultation was 4.2 years. The clinical picture was dominated by deafness which was constant in all patients. Tinnitus was present in 62% of cases. We retained 2 independent factors significantly predictive of functional failure: an age at surgery over 40 years and an audiometric stage III or IV of Aubry. Conclusion: Early post-operative air-bone gap is useful to detect early failure of stapes surgery. Although advanced otosclerosis was considered a negative factor for hearing gain, thanks to stapes surgery patients with advanced otoscle- rosis can better benefit from appropriate hearing aids.

Talasemia merupakan penyakit anemia herediter yang paling sering ditemukan terjadi akibat kondisi genetik dari sintesis hemoglobin yang tidak adekuat atau sintesis hemoglobin abnormal dalam eritrosit. Prevalensi talasemia alfa tinggi terutama di daerah tropis dan sub-tropis (seperti Asia Tenggara, Mediterania, Timur Tengah, dan Afrika) dimana prevalensinya sebesar 12-50%. Pada sebagian besar kasus, talasemia alfa tidak menimbulkan gejala klinis berat dan jarang membutuhkan terapi transfusi darah rutin. Pada kasus An. K, usia 13 tahun, datang ke Poli Anak RS. RSUD H. Abdul Manap dengan keluhan lemas dan mau melakukan transfusi darah yang rutin dilakukan 1 bulan sekali. An. K didiagnosa menderita Talasemia alfa. Setelah dilakukan pengumpulan data secara retrospektif didapatkan hasil Analisa DNA bahwa pasien merupakan penderita talasemia alfa/ penyakit HbH dengan jenis mutasi heterosigot ganda Hb Adana dan Hb Constant Spring sehingga membutuhkan transfusi darah rutin.

The current study assessed how 5 stress protocols applied affected sperm parameters, lipid profile, and some reproductive hormones. Live materials of the study consisted of 50 rats. The number of rats in the groups was equal and they were randomly assigned. Each group consisted of 10 rats. No stress application was conducted in the control group. The rats in the psychological stress group were subjected to a cycle of 4-hour light and 20-hour dark per day. The rats in the physical stress group were deprived of feed and water for two hours per day. In the psychological stress + physical stress group, the psychological and physical stress protocol was conducted. In the first 4 groups, all the applications were conducted for 14 days. A different stress application was applied to the rats in the depression group every day. It was determined that the abnormal sperm rate was high in the stress and depression groups, but the highest rate was in the depression group. In addition, sperm motility and sperm concentration were the lowest in the depression group. While the stress and depression groups had significantly lower serum triglyceride and HDL levels and LH and FSH levels, cholesterol and LDL values were significantly higher. Bax expression and 8 OHdG expression were severe in psychological stress+physical stress group and depression group. When the findings are evaluated collectively; it was determined that stress negatively affected sperm parameters, lipid profile, reproductive hormones, immunofluorescence and immunohistochemical parameters.

The objective of this study was to uncover the milk composition traits of Norduz sheep, which are bred in the Gürpınar district of the Van province, during the mid-term lactation period. The chosen ewes exhibited no signs of clinical or subclinical mastitis. A total of 104 sheep milk samples were meticulously collected to undergo comprehensive milk composition analysis. The chemical and physical attributes of Norduz sheep milk were methodically determined utilizing a milk autoanalyzer. The mean values for various milk constituents were as follows: milk fat (%), 2.48±0.11; solids-not-fat (SNF) (%), 10.76±0.08; milk protein (%), 5.09±0.04; lactose (%), 4.79±0.04; pH, 6.93±0.02; conductivity (mS/cm), 4.41±0.04; freezing point (°C), -0.602±0.80; salt (%), 0.8035±0.66; and density (kg/m3), 1039.73±0.39.

The Covid-19 pandemic has had a significant impact on the world of education. Therefore, the government, through the relevant ministries, makes crucial policies by imposing distance or online learning. In an effort to support this learning, the government has also implemented an internet quota program for students by deactivating various social media so that students focus on learning. However, it cannot be denied that there are obstacles in learning. The results of the questionnaire show that network constraints play a major role in learning. With intermittent sound, the network which often crashes is enough to disrupt the online learning process. The solution offered by students' parents is to change the provider or wait until the network is normal. The dominant solution in the results of this study is to carry out learning variations, namely face-to-face and online as well as recording material and adding learning applications so that if there is a disruption to the learning network, the learning continues because the material is already stored on the students' or parents' mobile phones. All obstacles can be overcome thanks to good cooperation between schools, especially support teachers, parents and students.
Gender-Based Violence and Global Capitalism: Everyday experiences of female laborers in the fast fashion garment industry
Authors: Febrilly Vanesha , Siscawati Mia
Published: October 2023

The garment industry is an industrial sector that recruits more female laborers. However, female laborers in the garment industry often experience various forms of injustice and acts of violence, such as low wages, gender discrimination or high workloads. Various forms of injustice and violence must be studied continuously, considering that this industry is still rapidly growing globally. The emergence of the fast fashion trend encourages the expansion of the garment industry, which can potentially eternalize injustice and violence against female laborers. Female garment laborers bear a substantial role in the production sector, starting from preparing materials, cutting materials, sewing, ironing, and playing various roles as helpers in various production processes. This paper  examines daily experiences of injustice and violence experienced by several female garment laborers from one of the garment factories in Jakarta.  Adopting the theoretical approach of feminist everyday political economy, this paper analyzes those experiences that reflect miscellaneous structural and cultural gender violence heavily influenced by global capitalism.
