Modern arable land in the Republic of Tyva is located on chestnut soils (69%) and chernozems (25%), but the former are characterized by low fertility. Soil fertility depends on the particle size distribution, structure, water-air regime, etc. Durind agricultural use of soils, the disturbance of the structure, especially of light particle size distribution, as well as depletion of humus and nutrient reserves can occur in them. Therefore, the aim of our work was to identify the influence of fallows on the change in the waterphysical properties of chestnut soils of the BarunKhemchiksky district of the Republic of Tyva. The chestnut soils of fallow and arable lands of the Barun-Khemchiksky district of the Republic of Tyva with the laying of two soil sections in arable and fallow fields were chosen as the object of the study. Soil samples from two horizons (arable and subsurface) were selected by the five-spot method. The water properties of these soils were subjected to the following analyzes: determining the water permeability of the soil according to the method of N. A. Kachinsky, determining the speed and height of rising water, determining the total capillary moisture capacity. As a result, it was found that the soil cover of the studied territories is represented by light loamy chestnut soils. Samples of fallow soil showed good water permeability with the amount of incoming water 80–100 mm per 1 hour. The water-lifting rate of soil arable land samples is slightly greater than the soil samples of the fallow: the soil sample of the arable layer of the arable land was completely moistened after 20 minutes, and the soil sample of the arable horizon of the fallow – only after 40 minutes. The moisture capacity of the fallow soil samples turned to be slightly higher than the arable land. An analysis of the studied samples indicates the improvement in the water-physical properties of the chestnut soils of the fallow compared with the arable field. Relatively low moisture capacity and accelerated water capacity indicate a destroyed and dispersed structure of arable land.
USE OF INDUCTION HEATING FOR REPAIRING ELECTRIC MOTORS

Published: February 2021

The quality of the production process depends on the reliability of technological and electrical equipment. The technological process of repairing electric motors includes the assembly of the electric motor and its installation. To date, the dominant position for performing this operation is occupied by the methods of “sledgehammers” or “oil baths”. The assembly of the electric motor can be carried out after heating of its individual parts. Both of these assembly methods are quite time-consuming, time-consuming and require significant physical strength from the maintenance staff. One of the main tasks is to heat the motor housing to the required temperature, which ensures the free installation of the stator and rotor. The possibility of using induction heating at the final stage of repair of an electric motor is considered. Induction heating is the heating of conductive bodies in an electromagnetic field due to the induction of eddy currents in them. In this case, electrical energy is converted into thermal energy due to its triple conversion. The intensity and nature of the heating are influenced by the current frequency, the strength of the electric and magnetic fields. By changing the indicated values, it is possible to obtain the necessary character of heating, its intensity and uniformity. For the study, the line equipment and the assembly process of 14 sizes of electric motor housings of the DATA and AIML series were considered. Calculation of heating temperatures for connection with interference fit of the DATA 63 electric motor housing with a stator and a rotor with a bearing was made. The calculation results of the heating temperature in two ways showed that using the induction method, the elements of the electric motor heat up 15% faster than during the operation of the heater. When creating the installation, the following requirements must be taken into account: high electrical and thermal efficiency, ease of maintenance, ease of controlling the heating process, and the possibility of its full automation. The use of induction heating allows one to automate the heating process and assembly of the electric motor, and makes it possible to increase the accuracy of the process without reducing operating time, increasing the stability and quality of the entire process.

The article presents data on biocenotic diagnostics of 12 farms in the Moscow region that are endowed with endometritis and mastitis in cows, as well as gastrointestinal and respiratory diseases of newborn calves, with the aim of identifying zoo-hygienic, zootechnical and veterinary deficiencies to optimize the strategy for dealing with them. Studies on biocenoses were carried out in 12 farms unsuccessful in cows’ obstetric and gynecological diseases, gastrointestinal and respiratory diseases of newborn calves, with a total number of cattle 12 254, including 4445 cows. For this purpose, field trips were periodically carried out for epizootological examinations of farm biogeocenoses and for the selection of blood serum stabilized with heparin and samples of pathological material for bacteriological, mycological, virological, hematological and immunological studies. It was established that in experimental farms there are no proper conditions to ensure the breaking of the epizootic chain during the infectious process. So, the main factors that contribute to the development and spread of these pathologies are poor food supply, violations of elementary veterinary and sanitary rules for keeping and milking, and failure to fully implement measures to prevent these diseases. An analysis of the epizootic situation for cattle diseases caused by conditionally pathogenic bacteria indicates that farms that are unsuccessful for factor infections have all the conditions for the circulation of pathogens, repeated passage through susceptible animals, the increase in the virulence of conditionally pathogenic microorganisms, and in some cases for appearing pathogenicity in saprophytic bacteria. An effective fight against malignant microbial ecosystems requires in-depth knowledge of the parasitocenoses’ quantitative and species composition, the study of relationships between its individual representatives, the mandatory identification of pure cultures of all its members, and determination of the microbial agents marker biological properties, as well as detailed biocenotic diagnosis of the animal habitat (farm, barn, etc.).

Numerous studies have shown that animals with the same genetic potential can differ in productiveness. In this regard, specialists in this industry, when predicting the milk productivity of adult animals in the process of raising young cattle, divide rearing into separate periods. In order to study the conditions for growing dairy calves, a comparative analysis of the conditions for keeping and feeding calves in two farms of the Republic of Tyva was carried out. The conditions of growing calves in the dairy period in the conditions of different farms with the same breed composition of cattle were studied. A comparative analysis of the influence of the composition and level of the diet on the growth of young animals is given. Calves of both groups by birth weight at birth did not have significant differences: they were 0.05-0.07 kg. In dairy farms MUP “KaaKhemsky” and “OOO Turanskoye” young cattle from birth to 6 months are kept in separate rooms. There are no significant differences in the calf feeding schedule. In the Municipal Unitary Enterprise “Kaa-Khemsky” feeding with haylage of young animals is introduced from two months of age; at the farm of “OOO Turanskoye” silage has been given to calves from 4 months. However, from 4 months to six months of age, they showed a significant difference in the increase in live weight. At 4 months, the difference averaged 4.27 kg, at 5 and 6 months – 6.39 and 8.59 kg, respectively. As a result of the studies, it was concluded that a decrease in the drinking of whole milk and the introduction of a substitute at its early, three-month-old age, which are compensated by a large intake of hay, feed and silage, do not provide a high average daily gain in live weight of the growing organism of young cattle.

Embryology (from the Greek embryon – embryo, logos – doctrine) is not just a biological discipline, but a science that studies the formation, development, and also the formation of embryos of living beings from the moment of the appearance of germ cells and their fusion until the birth of the world a new organism. One of the largest embryologists who studied the development of avian embryos, Hamilton, considering it amazing how the beginning of the functioning of one organ correlates with the functioning of other organs and systems of the body, writes: "It is not surprising that there are certain sensitive periods when the embryo is susceptible to disturbances both in the internal and and in the external environment". Quite a lot of literature is devoted to the issues of periods of hypersensitivity, or, as they are usually called, critical periods in the embryogenesis of various animals (invertebrates and vertebrates). The position of critical periods of development was first put forward by the English physician-scientist K. Stockard in the 20s. XX century And later it was deepened and expanded by the Soviet scientist-embryologist PG Svetlov. Periods of increased sensitivity to damaging influences in the embryonic development of fish are named. Omitting a large number of works, let us inform that Korovina, recognizing the stages of development and formation of a new quality at each stage, denies the existence of periods of increased sensitivity to the action of all environmental factors without exception. The author acknowledges that there are periods in embryonic development when embryos are equally sensitive to several influences, but considers it necessary to emphasize the specificity of the response to various environmental factors.

Published: February 2021

Статья посвящена исследованию вопроса нациестроительства в условиях современных социально-политических реалий Российской Федерации. Раскрывается значимость отмеченного процесса для страны, его влияние на уровень и качество консолидации российского общества. Необходимость переосмысления содержательных моментов данной тематики связана прежде всего с повышением порога угроз неуправляемого развития современности. На основе изученных материалов научной литературы, резолюций заседаний профильных органов власти в сфере реализации государственной национальной политики Российской Федерации, а также анализа данных отечественных и западных СМИ, приводится авторская категоризация обозначенных вызовов. Особое внимание уделяется таким проблемам, как использование этнического фактора западными государствами для дестабилизации внутриполитической ситуации в стране, недостаточный уровень профессионализма и отсутствие должной концентрации определенных органов государственной власти на достижении поставленных лидером Федерации целей. В результате проведенного исследования автор приходит к выводу, что, во-первых, задачи нациестроительства не будут реализованы в полной мере без широкого спектра деятельности в таких сферах, как культура, языковая политика, нормотворчество и др.; во-вторых, необходимо консолидировать усилия власти и общества в формировании единых норм внутреннего взаимодействия, чтобы нивелировать возникающие проблемы внутри государства и вовремя реагировать на внешние угрозы.

Published: February 2021

The author reflects on the possibility of implementing the idea of sustainable development in the environment of human life in various areas and between them. He begins by answering the question what is the human living environment, presents the typology of the areas that make up this environment and indicates the role of human in destroying it. Then, he analyzes selected pairs of areas of the human living environment that are opposite to each other (genuine – artificial, external – internal, natural – social, real – virtual, as well as local – global) because of the possibility of maintaining a balance within them and between them. The balance is a prerequisite for effective implementation of the idea of sustainable development. Finally, he made several conclusions resulting from his reflection.
Contemporary architectural interventions in the historical tissue of Cádiz – contextual minimalism in the service of genius loci
Authors: Białkiewicz Joanna
Published: February 2021

Discussions devoted to the contemporary approach to the historical heritage usually evoke strong emotions, residing somewhere between the conceptual poles of mimetic reproduction and ruthless anastylosis of forms and materials. Against this background, the four projects implemented in Cádiz, Spain, described in this paper appear to be very successful in their somewhat subdued formal character, the emphasis put on functionalism and space revitalisation, and the application of the concept of transparent architecture not conflicting with the historical one, non-aggressive, and at the same time thoroughly modern.

The connections between architecture and typhlology were not always obvious. Despite many related research problems, these sciences developed separately, and the study results of specialists from both departments did not reach the other discipline. An attempt to reduce this distance was made in the late decades of the 20th century by Polish architects, aware of the possibility of solving specific problems of the blind through architectural activities.

The work is an attempt to constitute an interdisciplinary relationship between architecture and typhlology. The author indicates and names common issues important for both sciences, and also attempts to outline areas of their potential cooperation. In addition, she also highlights the values ​​that can flow from this partnership.
ZNACZENIE MIEJSC SYMBOLICZNYCH W HISTORYCZNYM KRAJOBRAZIE MIASTA NA PRZYKŁADZIE LOKALIZACJI WIEŻY BISMARCKA W SZCZECINIE
Authors: Bielecka-Łańczak Oksana
Published: February 2021

W artykule przedstawiono problem, jakim jest tworzenie elementów kompozycji krajobrazu o znaczeniu symbolicznym zarówno w skali miasta, jak i całego regionu oraz ich wpływ na sposób zagospodarowania terenów sąsiednich, z uwzględnieniem zmiany znaczenia miejsca i jego charakterem. Z inicjatywy Związku Studentów Niemieckich podjęta została, zakończona ogłoszeniem konkursu w 1899 r., ogólnonarodowa akcja budowy „wież” poświęconych Bismarckowi, z płonącym na ich szczycie wiecznym ogniem lub też innych form mauzoleów wprost odwołujących się do starogermańskiej tradycji upamiętniania wybitnych władców lub mitycznych bohaterów. Stała się ona pretekstem do tworzenia całej serii kompozycji krajobrazowych na obszarze Rzeszy Niemieckiej. Wieża w Szczecinie może stanowić ważny przyczynek dla analizy i oceny zarówno kreacji, jak i deprecjacji przestrzeni symbolicznej, na skutek zmian politycznych, a także próby przywrócenia znaczenia i charakteru symbolu „wieży” trwale wpisanego w panoramę miasta.
UWARUNKOWANIA KONSERWATORSKIE W PLANOWANIU KRAJOBRAZU ZABYTKOWEGO NA PRZYKŁADZIE UZDROWISKA W SWOSZOWICACH
Authors: Myczkowski Zbigniew , Rymsza-Mazur Wojciech
Published: February 2021

Artykuł prezentuje uszczegółowienie wytycznych konserwatorskich, które określają dopuszczalne formy i zakres bezpiecznego, z konserwatorskiego punktu widzenia, rozwoju historycznego zespołu uzdrowiska w Swoszowicach we współczesnych uwarunkowaniach gospodarczych i społecznych, zapewniających prawidłowe wykorzystanie funkcji tego obiektu przy harmonijnym zachowaniu jego walorów zabytkowych i krajobrazowych. Taki postulat z jednej strony wychodzi naprzeciw stosownym zapisom ratyfikowanej przez Polskę w 2005 r. Europejskiej Konwencji Krajobrazowej (Konwencja Florencka, 2000) i stosownym wymogom prawodawstwa polskiego, z drugiej wpisuje się treść i brzmienie kierunków zagospodarowania przestrzennego Krakowa i perspektywę wsparcia jego kompleksowej metropolitalnej rangi. Tym bardziej że potencjał swoszowickich wód ma udowodnioną od ponad stulecia europejską z kolei rangę, której bieg historii nie pozwolił na optymalny rozwój uzdrowiska, a obecna chwila wydaje się taką możliwość realnie rysować. Wykazano, że rolę centrum swoszowickiego uzdrowiska od zawsze spełniał budynek Łazienek. Tutejsze Stare Łazienki, poza funkcją kąpielową pełniły od początku funkcję mieszkalną oraz rolę Domu Zdrojowego (odbywały się tu koncerty, spotkania towarzyskie). W latach 1860–1915 rolę centrum zdroju przejęły Nowe Łazienki, jednak po 1922 rola ta powróciła do budynku pierwotnego. W innych galicyjskich uzdrowiskach centrum wyznaczone było początkowo przez pałac właścicieli zdroju (o ile istniał), a następnie Dom Zdrojowy lub reprezentacyjne budynki Łazienek położone zazwyczaj wzdłuż głównej osi deptaku. Słusznie zatem należy w tym obiekcie upatrywać punktu odniesienia do poszukiwania zasadniczej kanwy kompozycyjnej parku, jak z kolei obiekt Szwajcarki po północnej stronie traktu drogowego – jest istotnym punktem odniesienia zarówno dla kompozycji przestrzeni parku, jak i przede wszystkim dla poszukiwania bezpiecznych z konserwatorskiego punktu widzenia stref ingerencji inwestycyjnej nieszkodzącej historycznemu układowi, a wychodzącej naprzeciw współczesnym standardom obiektu uzdrowiskowego o europejskim potencjale. Zatem zachowując starożytną zasadę, mówiącą o priorytecie nieszkodzenia przejętej z przeszłości postaci zabytkowego zespołu parku uzdrowiskowego, można i należy wskazać te jego obszary, które w ramach stref i kierunków „dopuszczalnej ingerencji inwestycyjnej pod nadzorem konserwatorskim” pozwolą uzdrowisku na sprostanie europejskim standardom i wpisanie tego niezwykłego obiektu w strategiczną funkcję turystyki kulturowej, rekreacyjnej i zdrowotnej.

Doliny rzeczne, obok lasów, są podstawowymi elementami struktury ekologicznej krajobrazu w Polsce. W znacznej części to obszary zalewowe rzek, jednocześnie będące istotnym elementem systemów przyrodniczych, zarówno lokalnych, jak i ponadlokalnych – stanowią bowiem naturalne korytarze ekologiczne. Specyficzne warunki przyrodnicze panują w dolinach rzek podgórskich i górskich. Problematyka zagospodarowania dolin rzecznych jest omówiona na przykładach gmin podgórskich Wilamowice (woj. śląskie) i Strzyżów (woj. podkarpackie). Głównym celem artykułu jest ocena zgodności dotychczasowego i planowanego zagospodarowania dolin rzecznych wymienionych gmin z uwarunkowaniami ekofizjograficznymi (lokalizacja zabudowy, zagrożenie i ochrona przeciwpowodziowa, warunki gruntowo-wodne, zanieczyszczenie wód powierzchniowych i podziemnych). Istotna w prezentowanym temacie jest również problematyka gospodarki przestrzennej i jej rola w kształtowaniu krajobrazu i ochronie zasobów wodnych (w tym lokalizacji obiektów hydrotechnicznych, małej retencji, zalesień) z uwzględnieniem zapisów Ramowej Dyrektywy Wodnej Unii Europejskiej.

Published: February 2021

An antireflection (AR) structure that incorporates a subwavelength grating (SWG) is a promising candidate for suppressing the Fresnel reflection of a silicon prism used as a component of an injection-seeded THz wave parametric generator (is-TPG) to improve the efficiency in extracting THz waves. Here, a two-dimensional binary AR-SWG with a 20 μm period is designed and then numerically and experimentally realized. The measured transmittance of the AR-SWG is discovered to be greater than 80% from 0.5 to 4.0 THz and to exceed 90% from 1.25 to 2.83 THz. Moreover, the AR-SWG is tightly attached to the Si prism of the is-TPG by direct-bonding technology. Compared to the is-TPG without AR-SWGs, the output increases by 1.3–1.5 times from 1.09 to 2.52 THz. The improvement in THz light extraction efficiency is thus successfully demonstrated.
Crystallite size analysis of Al/Ni multilayer powder by synchrotron radiation X-ray diffraction
Authors: Yamashita Soto , Yamamoto Rino , Miyake Shugo
Published: February 2021

The self-propagated exothermic reaction characteristics of Al/Ni multilayer powders can be employed as heat sources and controlled by cold-rolling conditions. This feature depends on the heat propagation inside of crystal grains. Therefore, the crystallographic factor that relates cold-rolling conditions to exothermic characteristics should be identified. To determine the change trend in crystallite size with the increase in the number of rolling passes, the crystallite sizes in the Al/Ni multilayer powder were calculated using Scherrer’s equation, and precise X-ray profiles were obtained using the synchrotron radiation X-ray diffraction method. The results indicate that the crystallite sizes were refined by increasing the number of rolling passes up to 30; from 30 to 40 passes, however, the crystallite sizes increased. It is assumed that, in addition to the Al/Ni multilayer powder being thin and multilayered, the increase in crystallite size at 40 passes allows for the smooth propagation of heat, consequently improving the exothermic characteristics. Therefore, crystallite size is the dominant parameter in the relationship between rolling conditions and exothermic characteristics.
Effect of C- and Fe-doped GaN buffer on AlGaN/GaN high electron mobility transistor performance on GaN substrate using side-gate modulation
Authors: Villamin Maria Emma , Kondo Takaaki , Iwata Naotaka
Published: February 2021

Side-gate (SG) modulation on AlGaN/GaN high electron mobility transistor performance with C-doped GaN buffer (C-GaN) and Fe-doped GaN buffer (Fe-GaN) layer on GaN substrate is experimentally investigated. The SG contacts are located 6 μm from either side of the device mesa, and etched near the channel layer. SG modulation is done by two methods, that is, applying a fixed side-gate voltage (V
SG) bias while the DC characteristics are measured, and bidirectional dual sweeping the applied V
SG while measuring the on-state drain current (I
D). At fixed high negative V
SG, a drastic decrease in transconductance and I
D is evident for C-GaN as compared to Fe-GaN. Moreover, evidence of larger memory effect in C-GaN, is demonstrated as shown in the I
D hysteresis feature using bidirectional dual-sweep V
SG measurements. The I
D decreased at high negative V
SG is inferred to be due to the field modulation caused by the SG.
Effects of thermal expansion and degeneracy on ambipolar carrier mobility of non-peripherally hexyl-substituted phthalocyanine
Authors: Fujisaki Masataka , Fujii Akihiko , Yoneya Makoto , Tohnai Norimitsu , Ozaki Masanori
Published: February 2021

The origin of the negative temperature dependence of carrier mobility in a crystal phase of 1,4,8,11,15,18,22,25-octahexylphthalocyanine was studied by utilizing a charge transport simulation based on Marcus theory and density functional theory. In order to understand the unique negative temperature dependence of carrier mobility, the theoretical calculation was carried out by taking the thermal expansion of the lattice parameters into consideration. The calculated hole mobility exhibited the similar temperature dependence as the experimental results. In the electron mobility calculation, the negative temperature dependence could be simulated by considering the degeneracy of lowest unoccupied molecular orbitals as well as the thermal expansion.

Published: February 2021

Purpose: The objective of the present study is to examine how work engagement, job demands and organizational commitment affect turnover intention among employees in Penang manufacturing industry. Research Methodology: Quantitative approach will be used in this study by distributing the online questionnaire to collect data from a sample of 75 employees drawn from manufacturing companies in Penang, Malaysia. Results: The present study found out that work engagement and job demands have no significant relationship with turnover intention. Besides, the present study indicates that organizational commitment is negatively related to turnover intention. Limitations: In this research, only 75 employees from Penang manufacturing industry had participated in the study. Since this small number of employees could not represent the entire Malaysia population, the future research should expand to involve a bigger sample of employees from Malaysia manufacturing industry to collect more reliable results. Contribution: The findings of this research provide benefits to the Federation of Malaysian Manufacturing (FFM) and manufacturing companies as they can understand the devastation effects of turnover and be equipped with strategies to decrease the turnover rate. Keywords: Employee, Job demands, Manufacturing industry, Organizational commitment, Turnover intention, Work engagement
Accountability: a necessity to pro-poor service delivery in Municipal Councils in Uganda

Purpose: There is mounting fear that the present-day Local Government managers do not appropriately respond to pro-poor service delivery. Yet, the number of people lacking access to quality services is swelling. This fault has placed a growing burden on Local Governments to enhance local councilors' political accountability by ensuring that the basic services are made delivered to citizens with accountability. Given the different challenges and observed shortage of political accountability in Uganda, this study examined the contribution of political accountability towards achieving pro-poor service delivery in a Ugandan Municipality. Research methodology: Using five Focus group discussions, perspectives on accountability are debated as a foundation for improving service delivery. Limitation: The study covers only Uganda and may not easily be generalised to other countries. Results: Results indicate that political accountability is key to implementing a municipal development plan. Contribution: The study contributes to knowledge so that hands-on accountability holds potential and requires more consideration as a means to assimilate learning-based methods and role-players network to back up the delivery of pro-poor services. It is proposed that local councilors become more responsive to meet the growing need for pro-poor service delivery in a Municipal council.

Published: February 2021

This paper presents a case series of two neonates reporting with difculty in opening the eyes on the rst day of life. On ocular examination multiple adhesional bands are found between lids in both the eyes. On systemic evaluation a smooth philtrum, low set ears suggesting Edward's syndrome was revealed in baby A and baby B had posterior cleft palate, dermal erosions along with mandibular dysplasia revealing ectodermal dysplasia cleft palate syndrome. Transection under local anesthesia was done on both the babies. Examination post transection revealed normal eyelid function. Ankyloblepharon Filiform Adnatum (AFA) in a neonate should alert the ophthalmologist because it can be rarely associated with life threatening multi-systemic defects. This case series aims to highlight such rare presentations and exemplies the need for multidisciplinary approach. Early surgical intervention performed can reduce the risk of occlusion induced amblyopia and also helps in the detailed ophthalmologic examination later in life.

Background: The objective of any mastectomy is to rid the chest wall of any breast tissue but since the breast being unencapsulated, there is every chance that some amount of breast tissue may be left behind in the skin aps after resection.
As the remnant breast tissue is likely to be exposed to the same carcinogenic risk factors as the tissue removed. Hence, there is always a
possibility that the residual tissue may become the seat of a recurrence. To get rid the chest wall so far the residual breast tissue will Objective: be
minimal and the recurrence of breast carcinoma will be less. Patents Data source: of proven case of CA breast who underwent MRM at RG KAR

USE OF ULTRASOUND IN DELIVERING SPINAL ANAESTHESIA IN CASE OF
ANKYLOSING SPONDYLITIS
Authors: Das Suspa , Purushotham R. , Gopal Vinodh Krishna
Published: February 2021

Ankylosing spondylitis (AS) is a chronic inammatory disease
involving the axial skeleton and peripheral joints. It usually affects
human leukocyte antigen-B27-positive individuals. Due to
ossication of interspinous ligaments there is the formation of a
bamboo-like spine. There is limitation of movement of neck when
cervical spine is involved, thus making neck extension in general
anaesthesia difcult. Involvement of the temporomandibular joint
makes mouth opening difcult. Involvement of the cricoarytenoid
joints makes oral intubation even more difcult.
A RARE CASE OF PRIMARY SQUAMOUS CELL CARCINOMA AT
ILEOSTOMY SITE: CASE REPORT
Authors: Soni Hitesh , Kalia Saurabh , Mehta J M , Agarwal Manisha
Published: February 2021

Primary squamous cell carcinoma at ileostomy site is extremely rare and there are only eight reported cases prior to our
report. The present case report describes a patient of ileostomy formation 12 years prior to evaluation after total colectomy
who now presented with mass at stomal and parastomal site and underwent biopsy and Positron emission tomography (PET) scan. Tumor was
suspected and hence wide local excision with en bloc resection of the ileostomy and ileo-rectal anastomosis was done and histopathology showed
differentiated Squamous cell carcinoma (SCC), Grade 1. This case underlines the need of regular follow-up of patients with stomas to allow the
timely detection of stomal problems and the early diagnosis and management of the rare complication of parastomal squamous-cell carcinoma.
Also, persistent peristomal ulcerations and proliferative lesions must undergo biopsies to rule out malignancy. Wide local excision of the
carcinoma with en bloc resection of ileostomy and formation of new ileostomy at a different site is usually done to manage such cases.
Energisation Method for Offshore Wind Farms Connected to HVdc via Diode Rectifiers

Published: February 2021

Diode rectifiers (DRs) have been recently suggested as a viable alternative for connecting offshore wind farms (OWFs) to HVdc, eliciting growing interest from both industry and academia. However, energisation of DR-connected OWFs is not straightforward. The present study constitutes a proof of concept of a novel energisation method for DR-connected OWFs, in which auxiliary power is provided from the shore through the HVdc link and the dc bus bar of one or more WTs. The proposed method provides an alternative with minimal additional hardware, which can be easily extended to more WTs in the OWF, increasing reliability by providing redundancy. The study includes coinciding auxiliary loads with active and reactive power components and a semi-aggregated OWF model, in which every WT is individually represented in the string containing the energising WT. An additional sequence of simulation events is considered following the initial energisation sequence. Such sequence comprises wind power taking over the provision of the auxiliary power. The simulation results indicate that the proposed method is a suitable alternative for energising OWFs connected to HVdc via DRs.

The manuscript has been submitted to the CIGRÉ Symposium 2021.
A Very Low-phase-noise CMOS Ring VCO Intended for Sensor Interfaces
Authors: Esmaeilzadeh Mahin , Audet Yves , Ali Mohamed , Sawan Mohamad
Published: February 2021

We describe in the paper a ring voltage-controlled oscillator (VCO)
indicating an improved phase noise over a wide range of frequency offsets and
an extended frequency/voltage tuning range. The phase noise is improved by
leveraging a better linearity approach, while reducing the VCO gain and
maintaining wide tuning range. The proposed VCO is a block of a time-domain
comparator embedded in a monitoring and readout circuit of an industrial sensor
interface. An analytical model is extracted resulting in closed-form
expressions for both input-referred noise and phase noise of the VCO. Employing
the analytical expressions, the contributed noise and phase noise limitations
are fully addressed, and all the effective factors are investigated. The
prototype of the proposed VCO was implemented and fabricated in a 0.35 µm CMOS
process. The integrated VCO consumes 0.903 mW from a 3.3 V supply, when running
at its maximum frequency of 9.37 MHz. The measured phase noise of the proposed
VCO is -147.57 dBc/Hz at 1 MHz offset from the 9.37 MHz oscillation frequency,
and the occupied silicon area of circuit is 0.005 mm2.
3M-CDNet: A Universal Powerful Benchmark for Remote Sensing Image Change Detection
Authors: Song Kaiqiang , Jiang Jie
Published: February 2021

Abstract—While deep learning-based
methods have gained popularity and have made remarkable progress in remote
sensing (RS) image change detection (CD), the limited amount of available data
hinders the performance of most supervised methods. The CD networks transferred
or derived from other fields can be fronted with a weak generalization
capability. Developing a universal benchmark for performance evaluations based
on the available datasets is urgent. To address these problems, we proposed a
lightweight network, termed 3M-CDNet, which only requires about 3.12 M parameters. The lighter the network,
the easier it is to train and alleviate overfitting the limited amount of
data, resulting in a better generalization capability. 3M-CDNet has a flexible modular design that
achieves performance improvements by incorporating plug-and-play modules. 3M-CDNet gains accuracy improvements in two ways: (1) the application of
deformable convolutions (DConv) in
the backbone network to gain a good geometric transformation modeling capacity
for CD and (2) the application of an effective two-level feature fusion
strategy to enhance the feature representation capacity. 3M-CDNet gains a good
generalization capacity by incorporating effective “tricks” to alleviate
overfitting, in which online data augmentation (Online DA) is applied to increase the diversity of the training
samples, and Dropout regularization is
applied in the classifier. Extensive ablation studies
have proved the effectiveness of the core components. Experiment results
suggest that 3M-CDNet outperforms state-of-the-art methods on several optical RS
datasets and serves as a new universal benchmark. Specifically, 3M-CDNet
achieves the best F1-score, i.e., LEVIR-CD (0.9161), Season-Varying
(0.9473), and DSIFN (0.7031).
The Contactless Badge" designed IR - Thermometer Evaluating Temperature & Social/Physical Distancing by Fabricating the MLX90614 Thermal Sensor during Covid- 19 Global Emergency
Authors: Kumar Abhijeet
Published: February 2021

The proposed applied
research is based on the IR thermometer functions by introducing novel
additional application improvement and fabrication in the design. In this
study, the concept of the custom compact device (shape illustrates - “A Badge”)
that functions as same of existing products, measures the surface temperature
of a body whether received data processed by Microcontroller (AtMega328P).
Observations state that the device functions in a way that there is any thermal
change comparison of the ambient temperature (D-1 m). The mode is activated and
produces a sound by a buzzer that is inside it. For distance measuring, it
measures the intensity of IR radiation emitted by a body in a particular
direction and an area. The change in ambient temperature (D- 1 m) up to 99o
F then produces another sound to alert and read the temperature when it comes
across the body (with the sensitivity area of D-1m.). It will be an
optimum up-gradation at the level in primary healthcare instrumentation &
helpful to noncontact, quickly and accurately measure moving and high
temperature objects.
