Authors: Kravchenko Galina A. , Lvova Elvira L. , Makarov Alexey M. , Stolyarov Sergey V. 
Published: October 2020

Electrical machines are widely used in various branches of the national economy. In particular, electric motors are one of the main elements in electrical power generation systems. The electric machines used at this ensure reliable operation of individual power units and the entire power supply system in general. The reliability of engines’ operation is largely determined by the quality of its insulation, that is why the improvement of methods for controlling the isolation of high voltage asynchronous motors is an actual task.
The aim of the research is to develop a method of continuous automated control of electric insulation condition in stator windings of an asynchronous motor basing on the analysis of experimental and industrial operation data making it possible to estimate the dynamics of changes in the main insulation parameters.
The main elements showing reliability of high-voltage electric machines, applied electro-insulation structures, methods for controlling insulation resistance in a high-voltage electric motor are considered in the article. The research performed was based on the results of the experimental and industrial operation of the automated system of insulation control under working voltage at the real facility carried out by the group of companies «Energopribor» of the town of Cheboksary.
The analysis of existing methods for insulation control is given, the scheme of insulation control by superpositioning test current with the frequency which is different from industrial one. The authors propose the method to estimate the dynamics of resistance changes in insulation of stator windings of the asynchronous motor, to reveal its approximation to the maximum permissible state in the process of operation and in reserve shutdown. Software modeling was carried out, the results of which correspond to the data of experimental and industrial operation.
The results obtained during the research allowed to systematize the obtained experimental data, to modernize the hardware part of the diagnostic complex DUKAT-SCAD, to outline the criteria area for its applicability.

Authors: Braverman Mara , Brown Daniel , Acha E. Marcelo 
Published: October 2020

Fish metamorphosis is an important ontogenetic process with a key role on early stages survival and on successful recruitment to adult populations. The whitemouth croaker (Micropogonias furnieri) is an important commercial resource for the coastal fisheries of Argentina and Uruguay. Metamorphosis, using morphometric and morphological analyses during larval development was studied. Changes in morpho-meristic characters before and after metamorphosis were employed to determine the length interval of this transition by employing Principal Component Analysis. Individuals (n=430) from 4 to 41 mm standard length (SL) were collected in the Río de la Plata estuary (35.45º S, 56.35º W) in March 2006. Length ranges of individual´s developmental stages were associated with the presence of key morphological characters. During early life stages, M. furnieri changes from a big-headed, robust shape larva to a slender and more elongated body form. Most of the morphometric variables showed an inflexion point at 15.2 mm SL, with a 95% confidence interval of 14.0 – 16.4 mm. The anterior part of the body grows faster during early stages, probably related to an intense feeding activity strategy. The completion of pectoral fin rays and the onset of squamation determine the beginning of metamorphosis at 11-12 mm SL. At around 18 mm SL, squamation ends, first barbels develop and the sagittae otolith primordium is closed. The length-at-metamorphosis for M. furnieri was established between 9 to 18 mm SL, since all developmental characters studied highly overlapped at that interval. All those processes are indicative of the beginning of the juvenile period associated to the settlement and the start of a bottom-oriented life-style.

Authors: Hamid Nawaz Tipu  , Dawood Ahmed  
Published: October 2020

Abstract
Objective: The aim of this study was to describe and identify clinical presentation of primary immunodeficiency disorders (PIDs). Characteristic quantitative and qualitative immunological abnormalities have been described which help in establishing a definitive PID diagnosis.
Methods: Cross sectional study in Immunology department, Armed Forces Institute of Pathology, Rawalpindi, Pakistan, from Jan 2016 to Dec 2018. Sixty patients of different PIDs including humoral defects, combined immunodeficiency, phagocytic defects and other miscellaneous disorders, were diagnosed over a period of 3 years in our institute. Their clinical presentation and laboratory data are presented in this study.
Results: In 3 years, 40 (66%) males and 20 (33%) females were diagnosed, with 13 (21.6%) patients of humoral deficiency, 22 (36.6%) of severe combined immunodeficiency, 18 (30%) of phagocytic defects and 7 (11.6%) of other miscellaneous disorders. Maximum patients belonged to Punjab province, i.e., 23 (38.3%). Their mean age for initiation of symptoms was 7 + 12.6 months, while diagnosis was made at mean age of 26 + 39.28 months, in all groups combined. Respiratory infections were commonest presentation, in 46 (76.6%) patients. Also 46 (76.6%) patients had consanguineous parents. Presence of family history of PID in 27 (45%) patients is not associated with an earlier diagnosis (p 0.955). Each group of patients carried characteristic laboratory findings.
Conclusion: PIDs should be suspected in offsprings with warning signs coming from consanguineous parents. There is a need to introduce genetic diagnosis of PIDs in order to timely diagnose less characteristic PID presentations. Continuous...

Published: October 2020

Abstract
Lipomas in the submandibular region are very uncommon. Large submandibular neck mass (greater than 10 cm) with a rapid growth rate, may raise concern about possible malignancy of salivary glands. Failure to distinguish salivary gland tumour and liposarcoma from a lipoma may represent a medico-legal pitfall. It is very important for the surgeon to rule out liposarcomas when dealing with giant lipomas in such regions. We report a case of a 65-year-old male who presented in the OPD with complains of pain and a 15x12 cm, giant submandibular solitary lipoma of anterior neck which had rapidly increased in size. The diagnosis of lipoma was confirmed on physical examination, radiological investigations and Fine Needle Aspiration Cytology (FNAC). The Patient underwent surgical excision. The surgery produced excellent cosmetic results and no functional impairment. This study illustrates the literature regarding aetiology, epidemiology, followed by diagnostic and treatment modalities of submandibular lipomas.

Published: October 2020

Abstract
Objective: This project aimed at determining time-dependent ultrastructural and hematological changes taking place in blood stored in local blood banks of Khyber Pakhtunkhwa.
Methods: It was a longitudinal study with repeated measures design. Twenty healthy blood donors participated in this study. An amount of 250ml blood was collected from each donor and stored in Citrate Phosphate Dextrose Adenine-1 (CPDA-1)-containing blood bags. Within first four hours, baseline samples were taken while subsequent samples were obtained at 5 days interval till day 20 th . Structural changes in RBCs were observed under light and scanning electron microscope (SEM) at different intervals. Furthermore, hematological parameters and osmotic fragility were also determined.
Results: Remarkable alterations were seen in RBCs morphology. From 5th day onwards, multiple visible spicules were observed on the RBC’s outer membrane and more than 2/3rd cells were abnormal at day 20. There was a significant reduction in RBCs count and hemoglobin concentration while the remaining parameters remained unchanged. Osmotic fragility increased significantly over time, with &lt;1% haemolysis noted in baseline samples as compared to 2.4% haemolysis on day 20th (p?0.0001).
Conclusion: Prolonged storage of blood results in distorted RBCs morphology and increased fragility. Transfusion of such cells would potentially result in rapid lysis in patients with hepatosplenomegaly and conditions requiring multiple blood transfusions.
Keywords: Red cells storage, scanning electron microscope, osmotic fragility, Transfusion, Blood storage, hemoglobin.

KONSEP MURABAHAH DAN APLIKASINYA DALAM PERBANKAN SYARIAH
Authors: Hikmah Dwi Astuti  
Published: October 2020

ABSTRACT
In practice more Islamic banks use murabahah contracts than other contracts. Endemic characteristics that are certain in the amount of installments and margins also give rise to the perception that the use of murabahah contracts can reduce the level of risk of financing. In fiqh there is indeed no portfolio arrangement in Islamic financial institutions. Then institutionally, the choice of murabahah contract compared to other contracts is the most attractive, profitable and least risky option so that the bank is basically allowed to prioritize murabahah in its product contract.

INSTRUMEN DISTRIBUSI DALAM EKONOMI ISLAM
Authors: Saiful Anwar  
Published: October 2020

Abstract
Distribution in the Islamic concept does not only prioritize economic aspects where size is based on the amount of property owned, but also discusses how the use of human potential can be distributed, in the form of appreciation for the right to life in life. Then the distribution is expected to overcome the problem of income distribution between various classes in society. Therefore in Islam Allah SWT implies one form of social virtue, like zakat. If this is used as the concept of income distribution, the economic system will run smoothly and the community will prosper. Gap and hunger will easily be eliminated due to the prevalence of the distribution system. And in Islamic economics a person's wealth does not make the cause of others experiencing economic difficulties, both production and consumption. Therefore Islam provides clear boundaries in living this life, including regulating matters regarding distribution. The whole is to regulate so that there is no social inequality between one party and another party and have an impact on actions or counterproductive. Therefore Islam stipulates the existence of distribution instruments, including the principle of cooperation between mudharabah and musyarakah, the existence of zakat, infaq, alms and endowments as well as other assets or income owned.

Reassessing long-term drought risk and societal impacts in Shenyang, Liaoning Province, north-east China (1200–2015)
Authors: Tang LingYun , Macdonald Neil , Sangster Heather , Chiverrell Richard , Gaulton Rachel 
Published: October 2020

Abstract. The occurrence of two severe droughts in north-east China since 2000 has
raised attention in the risk presented by droughts. This paper presents a
historic drought series for Shenyang in Liaoning Province, north-east China,
from 1200 CE to the present with a reconstructed long precipitation series
(1906–2015) augmented with historical documentary accounts. Analysis of the instrumental series using a standardized precipitation index (SPI) and
extending it using historical records has produced a combined series
spanning over 8 centuries. The combined long series was analysed for
patterns in drought frequency, severity and typology. Three droughts
comparable to those since 2000 occur in the instrumental series during the
early 20th century (i.e. 1907, 1916–1918 and 1920–1921), and coeval
archival sources reveal the human impacts of these severe droughts. The
archival sources demonstrate how reduced vulnerability resulting from
societal and cultural changes in the early 20th century helped prevent
the loss of life experienced during comparable severe droughts at the end of the 19th century (1887 and 1891). Incorporating a longer temporal
perspective to drought analysis shows that onset is often earlier than is
documented explicitly within the archives, and so combined SPI series for a
region could provide an early warning of drought development expressed as a
water deficit in the previous year. Analysis of archival data provides a
rich historical description of impacts and societal responses to severe
drought. The archives provide a rich historical description of drought
impacts and responses at the personal and community level whilst also
detailing the different roles played by communities, state and international organizations in responding to events.
Organization of convective ascents in a warm conveyor belt
Authors: Blanchard Nicolas , Pantillon Florian , Chaboureau Jean-Pierre , Delanoë Julien 
Published: October 2020

Abstract. Warm conveyor belts (WCBs) are warm, moist airstreams of extratropical cyclones leading to widespread clouds and heavy precipitation, where associated diabatic processes can influence midlatitude dynamics. Although WCBs are traditionally seen as continuous slantwise ascents, recent studies have emphasized the presence of embedded convection, the impact of which on large-scale dynamics is still debated. Here, detailed cloud and wind measurements obtained with airborne Doppler radar provide unique information on the WCB of the Stalactite cyclone on 2 October 2016 during the North Atlantic Waveguide and Downstream Impact Experiment. The measurements are complemented by a convection-permitting simulation, enabling online Lagrangian trajectories and 3-D objects clustering. Trajectories rising by 150 hPa during a relatively short 12 h window are identified as ascents and examined in the WCB region. One-third take an anticyclonic turn at upper levels, while two-thirds follow the cyclonic flow at lower levels. Identified trajectories that reach a 100 hPa (2 h)−1 threshold are further categorized as fast ascents. They represent one-third of the ascents and are located at lower levels mainly. Both radar observations and simulation reveal the presence of convective updrafts in the WCB region, which are characterized by moderate reflectivity values up to 20 dBZ. Fast ascents and updraft objects with vertical velocities above 0.3 m s−1 consistently show three main types of convection in the WCB region: (i) frontal convection along the surface cold front and the western edge of the low-level jet, (ii) banded convection at about 2 km altitude along the eastern edge of the low-level jet, and (iii) mid-level convection below the upper-level jet. Frontal and banded convection result in shallow ascents, while mid-level convection contributes to the anticyclonic WCB outflow. The results emphasize that convection embedded in WCBs occurs in a coherent and organized manner rather than as isolated cells.
Finite element simulations for investigating the strength characteristics of a 5 m composite wind turbine blade
Authors: Muyan Can , Coker Demirkan 
Published: October 2020

Abstract. Full-scale structural tests enable us to monitor the mechanical response of the blades under various loading scenarios. Yet, these tests must be accompanied by numerical simulations so that the physical basis of the progressive damage development can be better interpreted and understood. In this work, finite element analysis is utilized to investigate the strength characteristics of an existing 5 m RÜZGEM composite wind turbine blade under extreme flapwise, edgewise and combined flapwise plus edgewise loading conditions. For this purpose, in addition to a linear buckling analysis, Puck's (2D) physically based phenomenological model is used for the progressive damage analysis of the blade. The 5 m RÜZGEM blade is found to exhibit sufficient resistance against buckling. However, Puck's damage model indicates that laminate failure plays a major role in the ultimate blade failure. Under extreme flapwise and combined load cases, the internal flange at the leading edge and the trailing edge are identified as the main damaged regions. Under edgewise loading, the leading edge close to the root is the failure region. When extreme load case is applied as a combination of edgewise and flapwise loading cases, less damage is observed compared to the pure flapwise loading case.

$ \lambda(P)$-nuclearity of locally convex spaces having generalized bases
Authors: Deheri G. M. 
Published: October 2020

It has been established that a $DF$-space having a fully-$\lambda(P)$-basis is $\lambda(P)$-nuclear wherein $P$ is a stable nuclear power set of infinite type. It is shown that a barrelled $G_1$-space $\lambda(Q)$ is uniformly $\lambda(P)$-nuclear iff $\{e_i,e_i\}$ is a fully-$\lambda(P)$-basis for $\lambda(Q)$. Suppose $\lambda$ is a $\mu$-perfect sequence space for a perfect sequence space $\mu$ such that there exist $u\in \lambda^\mu$ and $v\in \mu^x$ with $u_i\ge \varepsilon >0$ and $v_i\ge \iota >0$ for some $\varepsilon$ and $\iota$ and for all $i$. Then the following results are found to be true. (i) A sequentially complete space having a fully-$(\lambda,\sigma \mu)$-basis is $\lambda(P)$-nuclear, provided $\mu$ is a $DF$-space in which $\{e_i,e_i\}$ is a semi-$\lambda(P)$-basis. (ii) Suppose $\{e_i,e_i\}$ is a fully-$(\lambda, \sigma \mu)$-basis for a barrelled $G_i$-space $\lambda(Q)$. If $\mu$ is barrelled and $\{e_i,e_i\}$ is a semi-$\lambda(P)$-basis for $\mu$ then $\lambda(Q)$ is uniformly $\lambda(P)$-nuclear. (iii) A $DF$-space with a fully-$(\lambda, \sigma\mu)$-basis is $\lambda(P)$-nuclear wherein $(\lambda,\sigma\mu)$ is barrelled in which $\{e_i,e_i\}$ is a semi-$\lambda(P)$-basis.
