Published: July 2022

Al-based automotive alloys with different level of Si content has been conducted on the characterization of machined surfaces in terms of roughness, temperature, chips formation as well as microstructue evaluation under different machining conditions. For this experiment a shaper machine with HSS single point V-shaped cutting tool is used at different cutting speed and depth of cut. The experimental results show that the surface roughness of the alloys decresess with cutting speed and depth of cut but it is more prominent on cutting speed. It is because of high cutting speed is more associated with the higher cutting temperatur and softening the work material leading to better surface finish. Higher Si added alloys shows the better surface finish due to formation of different intermettalics as more brittle. For brittle and higher hardness it produces the higher temperature during machining. During machining relatively curly and short chips are form by the high Si added alloy becase of its low elongation properties. Fracture surfaces of higher Si added alloy display more crack propagation obtained by the plate-like Si rich intermetallics.

Penerapan teknologi komunikasi satelit pada umumnya menggunakan frekuensi c-band sehingga menyebabkan alokasi frekuensi tersebut makin terbatas. Permasalahan yang ada pada sistem komunikasi satelit yaitu belum menggunakan frekuensi ku-band. Penggunaan frekuensi berbeda tentunya memiliki performansi yang berbeda dengan adanya pengaruh dari ukuran diameter VSAT dan redaman hujan. Pada penelitian ini bertujuan untuk mengetahui pengaruh diameter antena terhadap kualitas penerimaan komunikasi VSAT dan menganalisa pengaruh redaman hujan pada komunikasi VSAT dengan frekuensi ku-band dan c-band. Penelitian ini menggunakan Matlab untuk menghitung parameter link budget dan metode prediksi redaman hujan model ITU-R P.618-5 berdasarkan data parameter link yang diperoleh dari PT.Telkomsat. Hasil penelitian ini diperoleh bahwa performansi VSAT penggunaan ukuran diameter antena 1 meter, 3.8 meter, dan 4.5 meter untuk frekuensi Ku-band menghasilkan masing-masing parameter Eb/No sebesar 10.67 dB, 15.91 dB, dan 16.17 dB. Sedangkan untuk frekuensi C-band diperoleh nilai 12.6 dB,17.27 dB, dan 17.45 dB. Berdasarkan hasil tersebut maka diameter antena yang 1 meter merupakan yang paling efektif. Serta penggunaan frekuensi ku-band memiliki kelemahan terhadap redaman hujan dengan nilai redaman sebesar 35,37dB pada curah hujan 145 mm/h, sedangkan pada pengunaan frekuensi c-band tidak terlalu terpengaruh dengan redaman hujan dengan nilai redaman 2,25 dB pada curah hujan yang sama.

Published: July 2022

In this study, we used extract from Roselle (Hisbiscus sabdariffa L.) Calyx to determine its ability as an antioxidant supplement to improve motility, progressive score and abnormality of goatâ€™s sperms. Pooled semen from four male goats with average of live body weight 34.4 Â± 0.6 kg and body condition score 2.5 Â± 0.1 were aliquot into two groups: Control group; 0 mg/ml and Treatment groups; (Treatment 1:13 mg/ml, Treatment 2: 20 mg/ml, Treatment 3: 33 mg/ml, Treatment 4: 43 mg/ml of Roselleâ€™s extract. All the semen parameter was observed at 0 hour, 0.5 hour, 1.0 hour, 1.5 hours after semen collection. The supplementation of extender with 13 mg/ml, 20 mg/ml, 33 mg/ml, 43 mg/ml of extract from Roselle Calyx does not affect sperm motility, progressive score and morphology of goat (p>0.05). However, all sperm, regardless with supplementation and without supplementation of Roselle extract were maintained in good quality (60%) up to 1.5 hours. It is quite difficult to conclude that there are no effect of Roselle extract on sperm quality due toÂ arise possibility ofÂ factors that may contribute to inefficiency effect of Roselle extract on sperm parameter. There were high possibility that the causes are due to inefficiencies of extraction method and/or degradation of anthocyanin pigment during extraction and storage process. Unsuitable extraction method could results in low yield and unstable of anthocyanin pigment. Moreover, temperature, pH and light causes the pigment to become unstable during processing and storage leading to degradation. Thus we suggest anthocyanin content monitoring in extract Roselle Calyx are required for future study.

Quality of service management for an intent-based heterogeneous network using mobile QoE application
Authors: Beshley Mykola , Prislupskiy Andriy , Beshley Halyna 
Published: July 2022

Traditional Service Level Agreement (SLA) based on the quality of service (QoS) management methods are insufficient to ensure quality-related contracts between service providers and users. This article proposes a user-centric method for QoS management in heterogeneous mobile networks. Based on a new QoE metric on a scale of 1 to 5, this method considers the commercial value of electronic services to end-users. With this approach, the configuration and functionality of the network automatically change depending on the requirements of the end-users. The work proposes a conceptual model for constructing an intent-based software-defined heterogeneous network, which effectively manages shared resources and adapts to users’ needs. A prototype of a mobile and operator application for adaptive client-oriented service delivery in a heterogeneous network has been developed, which makes it possible to obtain the ordered QoE based on the feedback between the user and the network operator. Using this approach will allow network operators to provide individualization of service users with a certain level of QoS by analyzing their estimates of QoE (ordered through the developed mobile application). And the use of machine learning algorithms will allow to react to unfavorable combinations of values of quality indicators and prevent the situation when the user is not satisfied with the quality of services received for adaptive prediction of the moment of network reconfiguration. We propose a method for managing the QoS provision in a heterogeneous wireless network using Big Data technology and a mobile QoE application, which considers and analyzes the estimates of the ordered QoE and allows users QoS improvement according to the demand. It is demonstrated that using the proposed method in a heterogeneous wireless network allows reducing the number of dissatisfied users with the quality of service by up to 60% using an experimental study.
Features of cognitive disorders in patients with different forms of neurological and ischemic complications who underwent cardiac surgery
Authors: Mankovsky D. S. 
Published: July 2022

Objective — to study the features of cognitive impairment in patients with various forms of neurological and ischemic complications who underwent cardiac surgery (CS), to consider the data obtained in the development of rehabilitation programs for this category of patients.
Methods and subjects. We examined 700 patients who were treated at the Heart Institute of the Ministry of Health of Ukraine after undergoing CS with an artificial circulation procedure. The sample size is extremely large, and makes it possible to transfer the results to the entire population of patients who have suffered from CS. Among the examined patients the following groups were identified: a) patients with cerebral infarction (CI) in the postoperative period, numbering 86 people, the performance of patients in this group was compared with patients with CS without myocardial infarction in the postoperative period, numbering 614 people taken from the same sample); b) patients with signs of postoperative encephalopathy, numbering 217 people (which included patients with CI). The performance of patients in this group was compared with that of 483 patients with CS without signs of postoperative encephalopathy, taken from the same sample.
The study was conducted using the Trail Making Test, TMT (R. M. Reitan, Wolfson D., 1993); Verbal Fluency Test, VFT (M. D. Lezak, 1995); Stroop Color Interference Test (J. R. Stroop, 1935); Luria’s test for memorizing ten unrelated words (Luria AR, 1969). Statistical analysis of differences in the quantitative values of indicators was performed using the nonparametric Mann‑Whitney test.
Results. Our study found significant cognitive impairment in patients with CS. It was found that the presence of ischemic and neurological complications in the postoperative period significantly impairs cognitive function. The most significant negative impact on the cognitive sphere has the presence of CI in the postoperative period: patients with CI showed signs of severe cognitive deficits. Manifestations of cognitive deficits were also found in patients with postoperative encephalopathy, although the quantitative indicators characterizing cognitive functioning in this group of patients were better than in patients with CI.
Conclusions. The identified patterns should be taken into account when developing treatment, rehabilitation and preventive measures for patients with CS.

For almost 2 years, the SARS­CoV­2 pandemic has had a profound impact on the world of medicine and research. Research excitement caused by the new SARS­CoV­2 coronavirus may stimulate the study of demyelinating diseases (multiple sclerosis, acute disseminated encephalomyelitis acute), conversely, deepening our knowledge of the pathogenesis of demyelination and its association with viral infections may lead to studies in the immunopathogenesis of COVID­19. Technological advances that have been rapidly mastered to combat SARS­CoV­2 may soon be used to address multiple sclerosis. A striking example is the potential use of mRNA­based technology to develop tolerant vaccines that suppress CNS autoimmunity. Clinical trials are already underway to evaluate IFN­B, fingolimod, dimethyl fumarate, and masitinib (a tyrosine kinase inhibitor that is effective in phase 3 studies for primary progressive multiple sclerosis) as potent inhibitors of coronavirus.
The study presents a clinical case of acute disseminated encephalomyelitis (ADEM) associated with SARS­CoV­2 in a 39­year­old woman who was examined and treated at the Lviv Regional Clinical Hospital. The woman complained of severe dizziness, periodic numbness of the tongue, and snowlines of speech. From the anamnesis, it is known that from 07.05.2020 to 20.05.2020 she was treated for confirmed COVID19 infection in the Lviv Regional Infectious Diseases Hospital. Her condition was of moderate severity, she received an oxygen therapy. Neurological manifestations are horizontal nystagmus in both directions, high tendon and periosteal reflexes on all limbs, bilateral Babinski’s symptom, intentional tremor when performing a finger test on both sides. The diagnosis of demyelinating disease (possibly caused by COVID19) was established on the basis of serological studies (polymerase chain reaction to SARSCoV2), clinical findings, magnetic resonance imaging (multiple supra and infratentorial focal lesions of the white matter of the brain). The positive use of corticosteroids in the treatment of acute diffuse encephalomyelitis associated with SARSCoV2 has been reported. Thus, accurate diagnosis and timely treatment of acute demyelinating disease caused by SARSCoV2 virus are of great clinical importance.
The impact of sleep disorders on the formation and course of cardiovascular diseases. Review

Published: July 2022

It is well known that several common mechanisms of pathogenesis make the basis of formation of sleep disorders, hypertension, and type 2 diabetes mellitus (DM 2). First of all, one should take into account possible activation of the sympathoadrenal system, which underlies both the pathogenesis of hypertension and always accompane lack of quality sleep. It has been established that markers of systemic inflammation are raised in both chronic sleep disorders and hypertension and DM 2. Another unifying factor is the increase in aldosterone levels, which is characteristic of both sleep disorders and hypertension and DM 2. A number of studies have demonstrated the role of endothelial dysfunction in the development of chronic sleep disorders. Eating disorders, such as eating high‑calorie meals at bedtime, are both a risk factor for diabetes and sleep disorders. Normally, there are circadian rhythms of blood pressure regulation and insulin production and secretion, which can be observed in circadian sleep disorders. An important factor that contributes to the formation of sleep disorders in patients with hypertension and diabetes is the increase in anxiety and depression, which also often accompany both conditions.At the same time, it has not been established which factors exactly cause insomnia development in patients with hypertension and diabetes. Thereare no data on the occurrence of various sleep disorders in this group of patients in the Ukrainian population, the role of stress hormones in formation of chronic sleep disorders hasn’t been investigated. The most important factor from the point of view of a practitioner is the data on the effects of medicinal products for the treatment of hypertension and diabetes on sleep quality. The role of non‑medicinal correction, such as teaching patients the basics of sleep hygiene in the treatment and prevention of sleep disorders, has not been studied.Thus, insomnia can act as both risk factor for hypertension and diabetes mellitus and often accompany them, significantly affecting the quality of life of patients, treatment effectiveness, and prognosis in this group of patients.
