Authors: Arwa Azmeh , Mhanna Ali Boushra , Ahmad Alhasan
Published: July 2021

Purpose: To report unusual case of central retinal vein occlusion (CRVO) as the rst manifestation of Behcet's disease (BD) with coexistent hyperhomocysteinemia (Hcy) and homozygous MTHFR A1298C mutation.in a young male, and to provide a literature review regarding the role of Hcy and MTHFR mutations as risk factors for retinal vein occlusion (RVO) in BD patients. Methods: We are reporting a case of CRVO as the rst manifestation of BD with coexistent Hcy and homozygous MTHFR A1298C mutation.in a young male. A search was conducted in the Medline/pubmed database using keywords "CRVO, Behcet's disease, Hyperhomocysteinemia, homocysteine, MTHFR”. Full texts of 38 original articles directly related to the aim of the review were used. Results: A 30 year old male was found to have BD few months after presenting with Right CRVO. A lab work-up was carried for investigations of thrombophilia and possible coexisting autoimmune disorders, as possible causes for CRVO. Lab results revealed the presence of homozygous mutation of MTHFR A1298C subtype with Hcy, which was strongly suggestive of thrombotic pathophysiology for CRVO in our patient. Later the patient reported an episode of diarrhea with abdominal pain which appeared to be caused by stage 3 ciliac disease. Afterwords he started to have recurrent frequent episodes of painful oral ulcers, with an episode of genital ulceration and folliculitis like lesions on his back and shoulders. A diagnosis of BD was made and previous right CRVO was attributed to retinal vasculitis in the context of BD. The patient was well controlled on IV solumedrol followed by oral prednisolone and oral cyclosporine, which was later replaced by azathioprine 150mg. After a whole year of stabilization tapering of oral prednisolone was continued and by reaching a dose of 2.5 mg the patient had recurrence of right macular edema (ME) with signs of impending left CRVO, which was controlled again by raising oral prednisolone to 80 mg and azathioprine to 200mg. This led to right ME regression and left eye stabilization. While tapering again oral prednisolone and reaching a dose of 12,5 mg, impendig left CRVO progressed to CRVO with ME and right ME recurred. IV solumedrol was started again followed by oral prednisolone, azathioprine 200 mg with the add of iniximab. Both eyes became stable with total regression of ME. 6 months later, recurrent left ME was noticed and treated with suprachoroidal triamcinolone acetonide injection (SCTA). One week post SCTA, left ME regressed and remained stable through 1 month follow up. Conclusion: CRVO can be the rst presentation of BD in young patients. Associated homozygous MTHFR A1298C mutation and Hcy are possible risk factors for hypercoagulability state causing thrombotic complications in these patients

Published: July 2021

No processo de ensino-aprendizagem as atividades práticas ganham destaque, pois permitem a observação e aplicação de conhecimentos técnicos de uma forma que não seria possível esta experiência apenas com a teoria. Determinados conteúdos ministrados abrangem conceitos e técnicas difíceis de serem compreendidos apenas na teoria, mesmo ao se utilizar outros recursos como vídeos e estudos de caso, além disso, certas habilidades só podem ser desenvolvidas ou aprimoradas por meio das aulas práticas. Isso é  perceptível dentro da disciplina de Reprodução e Inseminação Artificial do curso de Bacharelado em Zootecnia. O objetivo do trabalho é relatar uma experiência de aula prática na disciplina de Reprodução e Inseminação Artificial do curso de Bacharelado em Zootecnia e a percepção da importância dessas práticas pelos alunos. O método adotado no presente projeto é a descrição da realização de uma aula prática e apresentação dos relatos dos alunos por meio dos relatórios de aula prática elaborados por eles. Os resultados mostram que a aula prática proporciona um ambiente favorável à participação e interação entre os alunos, de forma que em algum momento da mesma houve a participação de 100% da turma. Esta abordagem permite ainda o desenvolvimento de habilidades técnicas requeridas para a formação do futuro profissional bacharel em Zootecnia. Assim, aula prática no laboratório de Biotecnologia da Reprodução pode ser conifgurada como uma ferramenta metodológica exitosa na disciplina de Reprodução e Inseminação Artificial.

Authors: Abdullah Jumriah , Tasnim Tasnim , Banudi La
Published: July 2021

Background:Based on data from the Central Statistics Agency of Konawe Islands Regency in 2019, it is known that the number of Senior High Schools is 7 units, with a total of 1,717 students. The results of reports of teenagers who married before the age of 18 in 2019 were as many as 49 people. Based on this, the rate of early marriage in the last 2 years actually shows an increase. Researchers took the theme of early marriage because from the results of preliminary studies conducted by researchers, most adolescents have insufficient knowledge about early marriage and its effects on the social environment of adolescents. So it is not surprising why the rate of early marriage in Konawe Islands Regency is generally the third highest in Southeast Sulawesi Province.

Methods:This research is a quantitative research with a comparative study research type. The population in this study were 332 people and 179 samples with the sampling technique using stratified random sampling.

Result:Test results with the Mann Whitney Test The significant value for knowledge shows the value of p-value = 0.000 <value ? = 0.05 and the significant value for the social environment of adolescents shows the value of pvalue = 0.000 <value ? = 0.05, which means that there are differences in knowledge and social environment of adolescents in State Senior High School the Youth Counseling Program and Information are active and inactive towards early marriage.

Conclusion:There are differences in the knowledge and social environment of adolescents in the State MenengaAtas School where the Youth Counseling Program and Information are active and inactive towards early marriage.

Рассматривается гибкая MIMO антенная решетка для сетей пятого поколения, которая способна обеспечить работу в миллиметровом диапазоне волн (mmWave). Разработанная MIMO антенная решетка, способная обеспечить прием и передачу сигналов в диапазоне n258 (24,25-27,5 ГГц) и n261 (27,5-28,35 ГГц). При исследовании было определено влияние изгиба антенного элемента на характеристики матрицы рассеивания (S-параметры), диаграммы направленности, коэффициента полезного действия. При применении изогнутой MIMO антенной решетки было обнаружено, что при малом радиусе изгиба происходит улучшение коэффициента корреляции огибающей, при этом эффективность сложения в MIMO системе не изменяется при формировании изгиба. При исследовании рассматривались изгибы радиусом 100 мм, 250 мм, 500 мм. Применение изогнутых антенных решеток позволяет установить большее число базовых станций с антеннами миллиметрового диапазона волн, что позволяет обеспечить наилучшее покрытие 5G mmWave, так как именно в этом диапазоне волн достигаются основные характеристики сетей пятого поколения: малая задержка при передаче сигналов (1 мс), высокая скорость передачи данных (1 Гбит/с). Развитие сетей пятого поколения открывает новые возможности для каждого пользователя не только в области потребления информации, но и в технологиях Интернета вещей

The article discusses a flexible MIMO antenna array for fifth generation networks, which is capable of providing operation in the millimeter wave (mmWave). The developed MIMO antenna array is capable of providing reception and transmission of signals in the n258 (24.25-27.5 GHz) and n261 (27.5-28.35 GHz) ranges. In the study, we determined the influence of the bending of the antenna element on the characteristics of the scattering matrix (S-parameters), the directivity diagram, and the efficiency. When using a curved MIMO antenna array, we found that at a small bend radius, an improvement in the envelope correlation coefficient occurs, while the addition efficiency in a MIMO system does not change during bending formation. The study considered bends with a radius of 100 mm, 250 mm, 500 mm. The use of curved antenna arrays allows the installation of a larger number of base stations with antennas of the millimeter wavelength range, which allows one to provide the best 5G mmWave coverage, since it is in this wavelength range that the main characteristics of fifth generation networks are achieved: low signal transmission delay (1 ms), high data transfer rate (1 Gbps). The development of fifth generation networks opens new opportunities for each user, not only in the field of information consumption but also in the technologies of the Internet of Things

Приведено исследование, направленное на анализ различных решений для реализации архитектуры нейронной сети на программируемых логических интегральных схемах (ПЛИС) с использованием ускорителей с плавающей запятой. В частности, исследуются две разные реализации: высокоуровневая архитектура для создания нейронной сети на основе программного процессора с различными стратегиями повышения производительности процесса и низкоуровневая архитектура, построенная с использованием каскада арифметических элементов с плавающей запятой, синхронизируемых и координируемых конечным автоматом, описанным на языке высокого уровня VHDL, который реализовал вычисление с плавающей запятой полной точности за долю времени выполнения. Это может принести пользу модели, позволяя включать в систему стандартные интерфейсы (такие как JTAG или I2C), полезные для многих приложений, при сохранении RTL-контроля над потоком данных. Анализ производительностей каждой из архитектур сведен в таблицы. Результаты, полученные в ходе этой работы, могут перейти в новую форму реализации нейронной сети на ПЛИС. Приведены сравнения достигнутой производительности с точки зрения затрат времени и ресурсов ПЛИС, используемых для архитектур. Используя аппаратное ускорение программного процессора для операций с плавающей запятой, было реализовано и протестировано на производительность альтернативное полиномиальное приближение для функций активации

This article provides a study aimed at analyzing various solutions for implementing a neural network architecture on programmable logic integrated circuits (FPGAs) using floating point accelerators. In particular, two different implementations are being investigated: a high-level architecture for creating a neural network based on a software processor with different strategies to improve process performance, and a low-level architecture built using a cascade of floating point arithmetic elements, synchronized and coordinated by a state machine described in a high VHDL layer that implements full precision floating point computation in a fraction of the run time. This can benefit the model by allowing standard interfaces (such as JTAG or I2C) to be incorporated into the system that are useful for many applications, while maintaining RTL control over the data flow. I tabulated the performance analyzes for each architecture. The results obtained can go into a new form of implementation of a neural network on FPGA. I give comparisons of the achieved performance in terms of time and FPGA resources used for architectures. Using hardware acceleration of the software processor for floating point operations, I implemented and tested for performance an alternative polynomial approximation for activation functionse

Published: July 2021

Com intuito de contribuir com técnicas construtivas mais sustentáveis, nos últimos anos surgiram várias pesquisas experimentais com a substituição do agregado natural em concretos estruturais, por agregados de resíduo de construção e demolição (RCD). Diante disso, esta pesquisa realizou um levantamento bibliográfico de algumas pesquisas nacionais realizadas nesta área, com o intuito de verificar as tendências e divergências de comportamento entre os traços fabricados com RCD e elucidar boas práticas para as futuras pesquisas. Por meio da análise dos resultados, constata-se que o abatimento e a resistência à compressão do concreto são as propriedades mais afetadas negativamente pela substituição do agregado natural pelo agregado de RCD e que para obter um concreto com bom desempenho é necessário adotar medidas que visam melhorar as propriedades perdidas com a incorporação de RCD no concreto. Conclui-se que por meio de boas técnicas é possível produzir concretos com agregados de RCD com valores de resistência à compressão similares ao concreto convencional.

Alcoholism via 6-layer customized deep convolution neural network
Authors: Zhu Ziquan
Published: July 2021

Background: Alcoholism is caused by excessive alcohol into the human body. Alcohol primarily damages the central nervous system of the human body and causes the nervous system function disorder and inhibition. Severe addiction can lead to respiratory circulation center inhibition, paralysis and even death. So far, the diagnosis of alcoholism is done by radiologist's manual CT examination. However, the diagnosis process is time-consuming, subjective and boring for doctors. External factors, such as extreme fatigue, lack of sleep and mental concentration, can easily affect the diagnosis process.Methods: In order to solve this problem, this paper proposed a new neural network based on computer vision, which used deep convolution neural network to diagnose alcoholism automatically. A total of 216 brain images were collected. In the 6-layer customized deep convolution neural network structure, there were four convolution layers and two fully connected layers, and each convolution layer was connected with a pooling layer.Results: The results showed that the accuracy, sensitivity, specificity, precision, F1, MCC and FMI were 95.96%±1.44%, 95.96%±1.66%, 95.95%±1.67%, 95.73%±1.72%, 95.84%±1.48%, 91.92%±2.87% and 95.84%±1.48% respectively.Conclusion: It can be concluded from comparison results that the proposed neural network structure is more effective than four state-of-the-art approaches. The proposed method has high accuracy and can be used as a diagnostic method for alcoholism.

The correction of this disorder is always complex and combines various approaches: methods of behavior modification, work with school teachers, psychological and neurophysiological correction methods, as well as drug treatment. The main tasks of correction are to reduce the severity of attention disorders, improve psychosocial adaptation and academic performance. One of the promising methods for correcting attention deficit in an integrated approach is breathing exercises with hypoxic-hypercapnic loads, although experience with their application is unique.
Materials and methods. A total of 190 schoolchildren from Krasnoyarsk with attention deficit were examined. The energy state of the brain was studied using the NEK-5 computer-hardware complex. Correction of attention deficit was realized with the help of breathing exercises with hypoxic-hypercapnic loads.
Results. The study showed that younger students with attention deficit differ from the group of healthy children in terms of constant potentials in the cerebral cortex. The course of respiratory training with hypoxic-hypercapnic loads, in the correctional complex, in children with attention deficit leads to significant positive changes in energy metabolism, normalizes the functional state of the cortical centers, creates the condition for the development of cognitive functions.

Due to this reason, the realization of long-term projects on the stable usage of water resources in all activity spheres using international and regional practice became one of the prio- rities. In this respect, SOCAR started works on the advancement of projects on saving and reuse of water in industrial processes, treatment of industrial and municipal wastewater, desalinization of seawater as well. Desalinization units with antiosmosis are app-lied for satisfaction of water demand in offshore field platforms. The water supply networks, desalinated seawater, the water distilled in the units of biological treatment is used for the irrigation of green planting. Currently, Environmental Department of SOCAR started a pilot project in the Waste Management Centre (WMC) on the elimination of water shortage and increase of water use efficiency. WMC manages the unit of biological treatment of municipal wastewater and the unit for the treatment of industrial sewage as well. Moreover, a contract has been signed with “Ecol Engineering Service” CJSC on the treatment of industrial wastewater in 300 m3/month formed in the process of cuttings cleaning. In the future, cleaned water will be used for the irrigation and technical purposes to increase efficiency of water use.

Numerous research works justified that the main purpose of the stimulation of well operation is the productivity increase via elimination of the damages of bottomhole zone of the reservoir and well. This process occurs directly with creating a kind of structure in the reservoir. Thus, in the field conditions hydraulic fracturing, acid treatment of reservoirs, as well as the cracks (acidic hydraulic fracturing) are applied for the stimulation. The field studies showed that due to the radial flow character the major part of pressure decrease occurs near the well and at the bottomhole. The analysis justifies that any damage in this area significantly increases the pressure reduction and the effect of the damages may be presented by "skin-factor". The paper presents more generalized concept of "skin-effect" - one of the idealizations combining the most significant aspects of bottomhole and downhole damages of operation well. These processes create additional resistance, which decreases production. In our view, the well stimulation is productivity increase. In this case, there is a scientific-practical sense to review the stimulation as a method of reducing the "skin-effect" values. The paper offers a new "generalized skin-effect" or "generalized skin factor" parameter, which gives positive effect, i.e. increases the performance and productivity when occurs a negative value.

Die Fertigung und Prüfung geläppter Hypoidgetriebe basiert in der Praxis auf Erfahrungswissen und erschwert eine objektive Bewertung des Messverfahrens. Eine neu entwickelte Messstrategie nutzt simulierte Lastverschiebung und ein Bildverarbeitungssystem, um charakteristische Tragbildkennwerte aus erfassten Tragbildern in Mehrfachzahnkontakten zu extrahieren und erzielt unter Betriebsbedingungen erste vielversprechende Ergebnisse.

 

Current practices for manufacturing and testing of lapped hypoid gears exploit expert knowledge and impede an objective evaluation. A newly developed measurement strategy uses simulated load displacement and machine vision to extract characteristic contact pattern values in recordings of multiple tooth contacts. Early findings in operating conditions offer promising results and insights to this approach.

Additive Fertigungsverfahren zeichnen sich durch die Möglichkeit der endkonturnahen Fertigung komplexer Geometrien aus. Die geringe Produktivität etablierter Verfahren wie etwa dem Pulverbettverfahren hemmen aktuell den wirtschaftlichen Einsatz additiver Fertigung. Das Hochgeschwindigkeits-Laserauftragschweißen (HLA) soll durch deutlich erhöhte Auftragsraten und somit bisher unerreicht hoher Produktivität bei der additiven Fertigung dazu beitragen, deren Wirtschaftlichkeit zu steigern.

 

Additive manufacturing enables the near-net-shape production of complex geometries. The low productivity of established processes such as powder bed processes is currently limiting the economic use of additive manufacturing. High-speed laser direct energy deposition (HS LDED) is expected to improve the economic efficiency of additive manufacturing by significantly increasing deposition rates and thus previously unattained high productivity.

Daerah Irigasi Susoh merupakan salah satu daerah irigasi teknis yang terletak di Kecamatan Blangpidie Kabupaten Aceh Barat Daya. Pada Daerah Irigasi ini belum terdapat pembagian air secara rotasi sehingga diperlukan pembagian air secara rotasi/giliran. Tujuan dari penelitian ini adalah untuk mengetahui pembagian air sistem rotasi yang terjadi sepanjang tahun di daerah irigasi dan mengetahui alternatif pola tanam untuk mendapatkan Musim Tanam (MT)  berapa yang terjadi kekurangan air pada daerah irigasi Susoh sehingga pembagian air dapat teratasi dimana sebelumnya belum terdapat sistem rotasi pada lokasi ini. Tahapan penelitian adalah pembagian golongan luas layanan saluran sekunder berdasarkan skema jaringan irigasi Susoh. Perhitungan pembagian air dengan sistem rotasi/giliran berdasarkan data debit andalan dengan koefisien tanaman padi yang direncanakan adalah nadeco/prosida. Luas Daerah Irigasi Susoh adalah 2549 Ha dengan 51 petak tersier dan 9 saluran sekunder. Perencanaan sistem rotasi dimulai dengan penjadwalan musim tanam dilanjutkan dengan distribusi air pada MT III secara rotasi, sehingga didapatkan 3 golongan saluran sekunder yang akan dilkakukan pembagian air secara rotasi untuk setiap tahunnya. Hasil penelitian menunjukkan bahwa dalam satu tahun Musim Tanam hanya 2 kali Musim Tanam yang dapat dialirkan air secara penuh berdasarkan debit andalan yaitu November 4,81 m3/dtk, Desember debit andalan dengan 4,65 m3/dtk dan Januari dengan debit andalan 4,72 m3/dtk Musim Tanam I (MTI), Pada awal Maret debit andalan dengan 4,76 m3/dtk, April debit andalan dengan 4,57 dan bulan Mei debit andalan dengan 3,58 m3/dtk Musim Tanam II (MT II), Untuk awal Juli debit andalan dengan 3,00 m3/dtk, Agustus debit andalan dengan 3,30 m3/dtk dan September 3,20 m3/dtk. Musim Tanam III (MT III) debit aliran tidak mencukupi untuk kebutuhan air, sehingga kekurangan maksimal yang terjadi adalah -0,24 m3/dtk, sehingga direncanakan sistem rotasi pada Musim Tanam III (MT III).
