Design and analysis of a high-performance surface inset permanent magnet motor with asymmetrical rotor
Authors: Zhao Wenliang , Liu Cong , Li Yujing , Fan Xue , Wang Xiuhe
Published: September 2020

This paper presents a novel design strategy for surface inset permanent magnet (SIPM) motors to suppress torque pulsations and maintain the high output torque by integrating the magnet skewing and asymmetrical rotor configurations. The magnet skewing is implemented within one magnet pole pitch to reduce cogging torque by avoiding excessive torque degradation, and the asymmetrical rotor is designed to improve the utilization of the torque components, thus to compensate the decreased torque due to the magnet skewing. To highlight the advantages of the proposed motor, a conventional SIPM motor is adopted for performance comparison with the aid of the finite element method. As a result, the proposed SIPM motor highly reduced the cogging torque (−79.7%) and torque ripple (−54.7%) while maintaining a high average torque when compared to the conventional SIPM motor.
Probabilistic operation management of automated distribution networks in the presence of electric vehicles and renewable energy sources
Authors: Parsa Navid , Bahmani-Firouzi Bahman , Niknam Taher
Published: September 2020

Distribution automation is well recognized as an effective solution to enhance the reliability and efficiency of these grids in a timely manner. This paper introduces an effective probabilistic operation framework for the automated distribution networks (ADNs) incorporating the plug-in electric vehicles (PEVs) charging/discharging schemes in the presence of different renewable energy sources (RESs). To this end, this paper pursues four different strategic approaches. Firstly, an effective fuzzy based probabilistic method is proposed to model the forecast error in the wind and solar units well as the load demand through the cloud theory. Secondly, an appropriate framework is devised to model the PEVs random behaviour considering their essential parameters such as the charging/discharging rate and arrival/departure time to/from the parking lots (PLs), the discharging level at driving mode on the road and the effects of battery degradation. As the third goal, an appropriate objective function which can consider automation indices including the social welfare and reliability is considered. Since the operation problem is a nonlinear continuous non-numerical problem, it requires an applicable and effective optimization algorithm which is regarded as the fourth goal of this paper. In this regard, a new θ-modified bat algorithm is introduced to find the optimal solution of the problem. The proposed model is simulated and examined on the IEEE 69-bus standard test system wherein results reveal the effectiveness and applicability of the proposed operation management framework.

Published: September 2020

About almost 5- 6% of men who had vasectomy surgery come back to doctors for its reversal in the form of microsurgical vasovasostomy or simplified Loupe Assisted vasovasostomy. Vasovasostomy is a technique which is used to regain fertility in men. This technique, over the years, has gone through many advancements with better results, including one layer, two layers and now three layers microsurgery with equipments and techniques to form a meticulous anastomosis. While, on the other hand, simple Loupe Assisted technique is done using Prolene Stent. During vasovasosotomy it is extremely important to maintain normal blood supply to the tissues and muscle to build a tension free anastomosis.

In this modern age of in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI), it has become immensely important to clearly identify the outcomes of both the surgery procedures to void future issues after vasectomy reversal. Little data is present in comparison of the outcomes of both the vasectomy reversal methods. Therefore, this paper is compiled up to throw some light on case studies to better evaluate the best methods of reversal. A study was carried out in the hospital of bahawalpur from January 2017 to January 2019.

Authors: Kiyat Warsono El
Published: September 2020

Pisang merupakan salah satu komoditas unggulan Indonesia. Salah satu produk turunan dari pisang yang tinggi nilainya ialah wine. Namun, pisang mengandung berbagai polisakarida, seperti: pektin, pati, dan xilan yang dapat menyebabkan warnanya keruh dan kental bila dibuat wine. Berdasarkan hasil studi, proses enzimatis sari pisang dengan kelompok enzim lignoselulolitik (pektinase, selulase, dan hemiselulase) dapat mendegradasi polisakarida seperti pektin, pati, dan xilan pada sari buah pisang sehingga menghasilkan produk yang jernih dan yield yang lebih banyak. Penggunaan enzim α-amilase dapat meningkatkan kadar gula terlarut dan pereduksi sari pisang yang berpengaruh terhadap pembentukan etanol. Sonikasi secara tunggal tidak berpengaruh signifikan terhadap yield dan kejernihan sampel namun berpengaruh signifikan bila digabungkan dengan enzim pektinase dan selulase. Penggunaan jenis enzim yang berbeda dapat mempengaruhi dan memberikan presepsi sensori yang berbeda.

在过去的很长一段时间，中国的城市饮用水净化技术是比较传统和落后的，其主要的流程是从水源地把水取出来，然后在自来水厂进行初步的处理，然后在自来水的反应装置中加入水净化试剂以及消毒剂等等，去除水中的杂质、气味、毒害物质、微生物、虫卵等等，经过了初步的净化后水就会进入到沉淀池当中，通过一定的物理和化学反应将水中悬浮颗粒沉淀到池底，最后，再次进行水的消毒。这些措施一旦完成，那么就可以向城市的家庭和企业提供可以饮用的自来水了。然而，由于粗放式的经济社会发展情况，导致了水生态遭到了破坏，水污染的问题日益严重，过去常常使用的水净化技术已不再能够有效地处理水中的某些有毒有害物质，处理不彻底的水对人民的身体健康有严重的影响，所以说为了进一步改善和提高水处理和净化能力，满足城市饮用水的更高标准的要求，建议采用新一代的超滤自来水净化处理技术。

Documentary and guarantee function of Polish administrative court’s dissenting opinions in direct tax cases
Authors: Kowalski Patryk
Published: September 2020

This article presents the results of the examination dissenting opinions submitted by judges of Polish administrative courts in direct taxation cases in the years 2004–2018. The analysis covered the judgments of all sixteen administrative courts issued in the abovementioned period. These criteria led to the selection of research material covering a votum separatum from judgments on personal income tax, corporate income tax, inheritance tax, financial transaction tax, real estate tax. During the performed case studies using quantitative analysis it has been determined that, for example, dissenting opinions were very rarely submitted in comparison to the number of judgements issued by administrative courts. In the course of case studies using qualitative analysis it has been observed, that, for example, small number of votum separatum submitted from the rulings of the voivodship administrative courts regarding direct tax cases may indicate the predictability of the judicial process of applying tax law and, consequently, the implementation of the constitutional principle of legal certainty. It may indicate also the unambiguity of tax law and, consequently, the implementation of the constitutional principle of correct legislation (at least at the stage of first instance).

MELT PROPERTIES OF THE FOUR SALT SYSTEM AlF3-KF-NaF-ZrF4
Authors: Buhaenko Valery , Chupryna Volodymyr , Lysenko Oleh
Published: September 2020

The fusibility of salt mixtures in the anhydrous quadruple AlF3-KF-NaF-ZrF4 system was studied. The direction of lowering the melting point of substances in the tetrahedron of the composition of the quadruple system, the influence of complexation on lowering the melting point of salt mixtures, were clarified.

The fusibility of salts in the ternary AlF3-NaF-ZrF4 system was investigated experimentally by methods of thermal phase analysis. The diagram of fusibility to the isotherm of 900 °C is constructed. Primary crystallization fields are represented by the phases of the initial salts (AlF3, KF, ZrF4) of the compounds that were formed in binary subsystems (2KF∙ZrF4, 7NaF∙6ZrF4, 3NaF∙4ZrF4, 5NaF∙3AlF3) and Na3AlF6-Na3ZrF7 solid solutions. The minimum melting point was 466 ° C in a triple eutectic.

The fusibility of salt mixtures was experimentally studied in the subsystem K2ZrF6-Na2ZrF6-KAlF4-NaAlF4, which was a section of the tetrahedron of the composition of the quadruple system AlF3-KF-NaF-ZrF4. The fusibility diagram of this subsystem was constructed. A triple point with a melting point of 450 °C was found. Primary crystallization fields are represented by compounds K2ZrF6, Na2ZrF6 and solid solutions KAlF4-NaAlF4.

The low-melting region of the compositions in the tetrahedron of the composition of the quadruple system was shifted to the faces NaF-KF-ZrF4 and AlF3-KF-ZrF4. The intense chemical interaction of the starting materials of the quadruple system with the formation of complex compounds and the extensive formation of solid solutions complicated the determination of crystallizing solid phases and the establishment of monovariant equilibria in quadruple mixtures.

Quadruple eutectic in the four component system was formed by the merger of four monovariant lines. To calculate the composition of the quadruple eutectic by the melting temperature and the composition of the eutectic of the triple subsystems, the coordinates of the four triple points are necessary. The characteristic of two triple points was obtained as a result of an experimental study of the fusibility diagrams of auxiliary sections of a tetrahedron of the composition: K2ZrF4-Na2ZrF6-KAlF4-NaAlF4 and KZrF6-NaAlF4-(0,5NaF+0,5ZrF4)-KAlF4, which were located near the quadruple eutectic.

Published: September 2020

Previous publications reported the use of remote ischemic preconditioning (rIPC) as a non-drug method for increasing physical performance. However, the reported data are of a contradictory nature. Aim: to evaluate the potential of rIPC for increasing the physical performance of laboratory animals. The study was performed on 72 white outbred male rats. An assessment of the physical performance was carried out using a modiﬁed Porsolt test. The hind limbs of non-anesthetized animals were subjected to preconditioning. The results of a single and course (during 5 days) application of rIPC was evaluated. A single use of rIPC increased the average swimming time in the experimental group by 38.5%. The course application of rIPC did not lead to signiﬁcant changes in the indicators of physical performance in any of the animal groups.
