Published: October 2021

В данной работе
были измерены темновые и фототоки, проведено изучение роста методом молекулярно-лучевой
эпитаксии nBn-гетероструктур InSb/In1-xAlxSb на подложках InSb (001), где In1-xAlxSb является
широкозонным барьером (B). Ввиду наличия рассогласования между постоянными решетки
барьерного слоя и подложки InSb, необходимо определить оптимальную долю алюминия и толщину
барьера, при которой слой InAlSb будет псевдоморфным, для этого была выращена серия слоев InAlSb
с постоянной x=0.4, 0.3, 0.2 и переменной долей алюминия, в варизонных барьерах доля алюминия
изменялась от 0.4 до 0.1 (I) и от 0.35 до 0.15 (II) в процессе роста структуры от поглощающего слоя к
контактному. Контроль состояния поверхности в процессе роста проводился методом дифракции
быстрых электронов. После роста был проведен анализ
выращенных слоев методом рентгеновской дифракции с
определением степени релаксации слоя InAlSb.

Directional microwave coupled-line couplers with high lateral coupling level
Authors: Fanyaev I. A.
Published: October 2021

Classic сoupled-line couplers with a high lateral coupling level by type of directivity are counterdirectional. Restrictions on their synthesis are imposed by the gap between transmission lines, which must be extremely small (tens of microns), the difference in the phase velocities of even and odd modes, which must be compensated and others. This makes it difficult of manufacturing couplers. Described in technical literature сoupled-line couplers with a high lateral coupling level with changed types of directivity are either quite bulky or have small dimensions due to the use of discrete inductors and capacitances, which complicates the technological process with surface mounting when implementing the final device. In this article we propose a compact сoupledline coupler with a high lateral coupling level, which implements power transfer to a single port (0 dB, crossover). The coupler topology uses periodic loops that are located between сoupled-line. The equivalent circuit of the coupled lines was calculated and analyzed for a single periodic stub. This allowed us to determine the necessary parameters and dimensions of the topology. The device is narrow-band (3 GHz ± 5 %), transmission coefficient minus 0.44 dB at the center frequency of 3 GHz, isolation for isolated ports is not less than 35 dB. The proposed compact coupler with a coupling level of 0 dB suits building distribution circuits in which it is necessary to exclude the intersection of transmission lines. The information on the synthesis of the 3 dB co-directional microwave coupler on coupled strip lines with lateral electromagnetic coupling is given. The coupler is characterized by a high isolation level with an isolated port, not less than 40 dB. The imbalance of the amplitudes between the working (through and connected) and the input port is minus (3.4 ± 0.8) dB.
Simulation of forward current-voltage characteristics for Schottky diodes with MOS trenches
Authors: Solovjov J. A.
Published: October 2021

Present work is devoted to the development of a mathematical model for the forward current-voltage characteristic of Schottky diodes with a metal – oxide – semiconductor (MOS) trench structure, which takes into account the accumulation of the main carriers in silicon near the walls of the trenches at a forward bias. The proposed model considers the decrease of the series resistance of the Schottky diode drift region with an increase in the voltage at the rectifying contact due to the enrichment of silicon with electrons near the walls of the trenches. The proposed model is compared with the experimental results for Schottky diodes with a metal – oxide – semiconductor trench structure with a nominal reverse voltage of 45.0 V and a nominal forward current of 50.0 A. It is shown that the error in calculating the direct voltage value for the new model does not exceed 1.2 % in the range of direct currents from 20.0 to 50.0 A, which is 4.6–9.7 times less than the calculation error for the classical model. The results obtained can be used to develop the structure and geometry of Schottky diodes with a metal – oxide – semiconductor trench structure with required electrical parameters.
Gallium nitride heterostructure field-effect transistor with a heat-removal system based on a trench in the passivation layer filled by a high thermal conductivity material
Authors: Volcheck V. S. , Stempitsky V. R.
Published: October 2021

The self-heating effect poses a main problem for high-power electronic and optoelectronic devices based on gallium nitride. A non-uniform distribution of the dissipated power and a rise of the average temperature inside the gallium nitride heterostructure field-effect transistor lead to the formation of a hot spot near the conducting channel and result in the degradation of the drain current, output power and device reliability. The purpose of this work is to develop the design of a gallium nitride heterostructure field-effect transistor with an effective heat-removal system and to study using numerical simulation the thermal phenomena specific to this device. The objects of the research are the device structures formed on sapphire, each of whom features both a graphene heat-eliminating element on its top surface and a trench in the passivation layer filled by a high thermal conductivity material. The subject of the research is the electrical and thermal characteristics of these device structures. The simulation results verify the effectiveness of the integration of the heat-removal system into the gallium nitride heterostructure field-effect transistor that can mitigate the self-heating effect and improve the device performance. The advantage of our concept is that the graphene heat-eliminating element is structurally connected with a heat sink and is designed for removing the heat immediately from the maximum temperature area through the trench in which a high thermal conductivity material is deposited. The results can be used by the electronics industry of the Republic of Belarus for developing the hardware components of gallium nitride power electronics.

Authors: Talukdar Mrinal , K R Prashanth , Paul Ratnadeep
Published: October 2021

Introduction: Acute pancreatitis (AP) is characterized by a spectrum of symptoms, ranging from a local inammatory process to the more severe
form (acute necrotizing pancreatitis) which is associated with a systemic inammatory response. The overall mortality rate of AP is between 5%
and 15%, reaching 30 % in severe acute pancreatitis (SAP). Early optimized care may improve prognosis in patients with severe forms but it
remains a challenge to identify these poor prognosis cases especially in the rst 48 hours. This study will evaluate the efcacy of serum D-Dimer in
prediction of severity and outcome of acute pancreatitis. A prospective observati Methods: onal study of 60 patients presenting with AP was done at
st st Silchar Medical College from 1 June 2017 to 31 May 2018. APACHE-II, Ranson criteria, and CT severity index (CTSI) of all patients were
calculated,. D-Dimer was done for all patients. The patients were stratied into categories of severe pancreatitis, organ failure and pancreatic
necrosis, as well as the number of deaths. The comparison of D-Dimer with other scoring systems was done by area under the receiver-operating
curve (AUC) to predict severity, organ failure, necrosis, and death. Of the 60 patie Result: nts, 15 (25%) developed SAP, 12 (20%) Organ failure
(OF), 22 (36.7%) pancreatic necrosis and 3 (5%) died. ROC curves were generated and following cut-off were selected for comparison of severity,
organ failure, necrosis and death; Ranson ≥ 3, APACHE II ≥ 8, CTSI ≥ 4. Cut-off of D-Dimer value for severity, organ failure, necrosis and death are
≥1397µg/L, ≥1886µg/L, ≥1890µg/L and ≥5769µg/L respectively. The AUC of D-Dimer (0.914) in predicting severity of disease is similar to
that of Apache 2 (0.958) and Ranson (0.899). CTSI (0.715) had lowest AUC among them. The AUC of D-Dimer (0.833) in predicting of organ
failure of disease is similar to that of Ranson (0.908) and lower than Apache 2 (0.980). CTSI (0.715) had lowest AUC among them. The AUC of
CTSI (0.892) in predicting the necrosis was higher than Apache 2 (0.590), Ranson score (0.578) system and D-Dimer. The AUC of D-Dimer
(0.953) in predicting of mortality of disease is similar to that of Apache 2 (0.933), CTSI (0.953) and lower than Ranson score (0.816). Conclusion:
D-Dimer is an easy tool for assessment of severity and prognosis of acute pancreatitis. CTSI is best for predicting pancreatic necrosis.

Surgical care is an integral component of health systems, and so is the appropriate management of the surgical wound. Excessive inammation and edema, in the post-surgical period, can result in delayed wound healing, infective complications and increased length of hospital stay, among other complications. Systemic enzyme therapy (SET) with trypsin and bromelain, in combination with the bioavonoid rutoside, has been extensively investigated as alternatives to conventional therapies for pain and swelling associated with many inammatory conditions. The multi-pronged pharmacodynamic action of these ingredients on different inammatory processes has been highlighted in this review. Additionally, clinical studies demonstrating the benecial effects of SET in multiple surgical settings, including general surgical, dental, orthopaedic, cosmetic surgeries, are also discussed

Published: October 2021

Phyllodes tumor is a rare neoplasm of female breast have its origin from the broepithelial cells of breast. It predominantly occur in females (0.3-
0.5%). Phyllodes in pregnancy are larger in size and rapidly growing may be because of the inuence of pregnancy hormones on the female breast
tissues. A 22 year old female with six months of pregnancy with phyllodes tumor of right breast was posted for wide local excision and
reconstruction of defect using latissimus dorsi myocutaneous ap. She had presented with swelling of approximately 24cm X10cm X 6cm in her
right breast which developed pain since last eight days. She was maintained on the intravenous injection duvadilan (isoxsuprine) 80 mg 8 hourly for
three days perioperatively for tocolysis. The case was done using thoracic epidural catheterization at T6-T7 interspace using 0.75% ropivacaine
with no perioperative complications. The choice of anesthetic technique for the emergency procedures in pregnancy will depend on the trimester
and the type and duration of surgical procedure. Whenever possible, a regional anesthetic technique should be used.

An oral modied release dosage forms have always been more effective therapeutic alternative to conventional dosage forms. The present
invention is directed to a modied release pharmaceutical composition of indomethacin by using hydrophilic release retardant polymers like
HPMC K15M, Na CMC alone or in combination. Matrix embedded prolong release tablet formulations of Indomethacin were prepared by wet
granulation technique and evaluated for tablet properties such as the thickness, hardness, friability, weight variation, drug content, drug release
kinetics and in vitro release studies. The inuence of drug polymer ratio on drug release was studied by dissolution test. The FTIR studies showed
no interactions among drug and polymers. The tablets formulation (F7 and F8) containing combined polymers of HPMC K15M and Na CMC
resulted in slower drug release rate form the matrix. So, it can be concluded that Indomethacin prolong release tablets using HPMC K15M and Na
CMC as the retardant has successfully extended the release of indomethacin from its formulations. The mixing of two cellulose polymers, ionic and
non-ionic, for the formulation of hydrophilic matrices, resulted in a valuable decrease in drug release rate. All the formulations showed KorsmeyerPeppa’s model as a best t.

Authors: Rastogi Priyank , Singh Arya Tungvir , Gupta Abha
Published: October 2021

BACKGROUND: There has been an alarming increase in the prevalence of Coronary Artery Disease (CAD) worldwide and is a leading cause of
mortality in India. Yoga is emerging as a signicant tool in managing the disease.
OBJECTIVES:The study was conducted to nd out the effect of yogic lifestyle modication on anginal episodes in CAD patients.
METHODS: This prospective, controlled study included the CAD patients between the ages 30 to 70 years who were randomised to yoga group
(group A, n=51) and control group (group B, n=51). They were assessed clinically on the basis of number of anginal episodes per week. The yoga
group patients were prescribed a family based yoga programme in addition to the conventional drug treatment for CAD. The control group received
conventional drug therapy alone. The patients were assessed at baseline and thereafter, at the end of 6 months.
RESULTS: The number of anginal episodes per week reduced signicantly by 25.40% in the yoga group vis-à-vis the control group at the end of
six months (independent t-test p-value<0.01). It was also inferred from the study that while at baseline, there was no statistically signicant
difference between the yoga and control groups (independent t-test p-value>0.05), the difference became signicant at the end of six months
(independent t-test p-value<0.05).
CONCLUSIONS: In the present study, we witnessed a substantial and signicant effect of yogic lifestyle intervention in decreasing the number
of anginal episodes per week in CAD patients thereby reducing the morbidity associated with the disease considerably

Climatic Bases and Analysis of Proposed Cloud Attenuation Model for Satellite Links Application
Authors: Adewusi Mustapha
Published: October 2021

Consistently required lager bandwidth at lower cost induce increases in magnitude of transmission frequency for satellite signal. This is phenomenally accompanied by proportional hydrometeors attenuation. Hence, there is need to evaluate cloud attenuation impact in every climatic region periodically. This report is one of the outcomes of experimental communication research carried out at tropical Ota (6.7oN, 3.23oE) station, southwest, Nigeria. The station spectrum analyzer measures its received beacons total attenuation at 12.245 GHz and elevation angle 59.9o to Astra satellites located at 28.2oE. Daily maximum, minimum and mean temperatures; rain amount, wind speed and direction as well as time of occurrence of each of these weather parameters were also measured. Then the radiometric data including acquired radiosonde data were analysed under rainy and non-rainy conditions, to obtain cloud attenuation contribution from the total attenuation measured per minute. The various data used range in measurement periods between four and fifty-eight years. The outputs were used to compute the station cumulative distributions for the existing cloud models and for the integrated station’s data. Statistical analysis comparing the two cumulative distributions show a high difference between the measured data and existing models’ predicted values. Hence a cloud attenuation computation algorithm and its simulation program were developed and used to derive a new tropical cloud attenuation model. The results of climatic data and analysis were used to justify the well corroborated new cloud attenuation model.

O envelhecimento é um processo natural que traz consigo efeitos deletérios que podem resultar em comorbidades, perda da qualidade de vida e morte. A Hipertensão Arterial (HÁ) a comete uma grande quantidade de idosos. A musculação é uma modalidade de atividade/exercício físico que utiliza manifestações da força como forma de sobrecarga. O objetivo do presente estudo foi avaliar e comparar, na literatura científica, com uma visão crítica, os efeitos dos protocolos de treinamento de musculação em diferentes manifestações da força (Força máxima, hipertrófica e de resistência) em idosos hipertensos no controle não medicamentoso da HA e os principais mecanismos desse controle. A revisão de literatura crítica apresenta a musculação como parte necessária para prevenção e tratamento não medicamentoso de idosos com HA, não especificando a relação com as diferentes manifestações da força (Máxima, Hipertrófica e de Resistencia). A musculação possui efeitos agudos e crônicos sobre a HA de idosos, sendo estes favoráveis a saúde e qualidade de vida dos mesmos, benefícios que são atribuídos ao ganho de massa muscular e força.

Rhinolithiasis is a rare condition in our current practice. We report the case of a 19 year old woman, presenting with a double symptom marked by rhinorrhea and chronic unilateral nasal obstruction evolving since the age of 7 years, without any known foreign body. Rhinoscopy and nasal endoscopy coupled with CT scan were decisive examinations for the positive diagnosis. The therapeutic management consisted in the extraction of the rhinolithiasis resulting in the vacuity of the nasal cavity. The evolution was favorable with simple postoperative courses.

A Cognitive Linguistics Diagnosing Of Iraqi EFL Students’ Difficulties in Using Synonyms
Authors: Nasser Sura Muttlak
Published: October 2021

Learning and teaching synonyms for Iraqi EFL students is a difficult task. Learning synonyms means learning how words can be related to each other. Understanding synonyms helps students to understand the meaning of the word easily and avoid mistakes committed in synonyms as a result of their knowledge concerning this area. Iraqi EFL students face difficulties in using appropriate synonyms. This study was conducted in the Department of English, College of Education for Women, University of Baghdad, to indicate first-year students’ incompetence in using synonyms. The participants of this study, fifty female students during the first semester, were chosen randomly for the academic year 2019-2020. In order to achieve the aim of this study, the researcher used pre and posttest as tools for collecting data. The data was analyzed by the SPSS program. Figures and tables were used to present the data. The present study reveals the difficulties that occurred when Iraqi EFL students used synonyms. This is due to the need for information about English equivalent words, then suggests suitable solutions for them. Also this study reveals that the domains theory has indeed been demonstrated to be effective in precisely understanding the semantic domains of English lexical concepts.
“¿Qué sos, Nicaragua, para dolerme tanto?” Gioconda Belli and the Nicaraguan Cause”
Authors: RocaMartinez Silvia
Published: October 2021

This article traces Gioconda Belli’s trajectory as a writer, feminist, and political activist. Belli, who is known as one of the organic intellectuals of the Nicaraguan Sandinista Revolution, has consistently used her platform as one of the most renowned contemporary Latin American writers to provide a voice that transcends national borders to the Nicaraguan cause since the early 1970s. Through the analysis of some of her most notable works, some of her contributions in the national and international press, as well as social media publications, we examine the way her many roles have informed each other over the years and accomplished a two-fold goal: on the one hand, she has documented and theorized on the recent history of Nicaragua, in addition to keeping those in power in check; on the other hand, she has become one of the foremothers of Nicaraguan feminism. As this article shows, not only has she crafted—both in writing and action— a roadmap for younger generations of women, but she has also documented and influenced the evolution of feminism in Nicaragua.

Published: October 2021

Purpose: Тo determine the possibilities of quantitative assessment of mpMRI with EOB-DTPA in the differential diagnosis of benign and malignant tumors in children.

Material and methods: 30 patients (male — 17, female — 13) with 83 tumors underwent MRI. Age ranged from 5 months to 20 years. All children underwent MRI on 3T or 1.5T MR-scanners using body coil. Fat saturated T1WI were performed before and after hepatotropic MR-contrast agent (gadoxetic acid) injection in arterial, portal, venous and delayed phases (1, 5, 20, 40 min). Tumors were divided into 2 groups: benign (52) and malignant (31). In this work we use only pre- and postcontrast T1WI. Diagnosis was confirmed histologically (all malignant and a part of benign FLL) and long-term MRI follow-up studies (for benign). To eliminate influence of external factors we used coefficients for each MR-program, the signal was normalized to intact liver parenchyma, spleen, abdominal aorta and v. cava inferior, also normalization to native series has been performed. Coefficients were compared for malignant and benign tumors using Student’s t-test, significantly different parameters were further used to build mathematical model by constructing a logistic regression with step-by-step selection of the most informative values.

Results: Regression model is presented by formula. The model is informative and statistically significant (p < 0.001). If A>0.5 tumors has a malignant nature if А ≤ 0.5–benign. Model sensitivity and specificity are 0.862 and 0.925, respectively.

Conclusion: Our model could be an excellent assistance in differentiation of benign and malignant focal liver lesions and reduces diagnostic path, effects the proper patients management.

Published: October 2021

Purpose: Assessment of the capabilities of the ultrasound method in the diagnostics of a rare Hurthle-cell tumor of the thyroid gland on the example of a clinical case of a patient with malignant neoplasms of independent primary multiple localizations in comparison with other research methods.

Material and methods: A comprehensive study of materials from the history of the disease, the results of clinical, laboratory, instrumental, morphological research methods and their comparison with diagnostic cases from literature data.

Results: Despite the full comprehensive examination of the patient, including ultrasound, MRI, PET/CT, puncture biopsy under ultrasound control, it was not possible to make the correct diagnosis before the operation. The presence of other malignant diseases in the patient’s history, the presence of altered paratracheal nodes in the same zone, and the rare occurrence of Hurthle thyroid tumors played a role.

Conclusions: Hurthle-thyroid cell tumors are a rare disease, but it must always be taken into account in the diagnostic search, since even benign Hurthle tumors have a high risk of malignancy and spreading of distant metastases.

The year 2020 was the year of infectious diseases with the arrival of SARS-CoV-2, which represented a profound change in the world we knew. However, we present a brief description of some of the top infectious diseases articles from 2020 not related with SARS-CoV-2. We reviewed a selection of the most important and relevant achievements in diagnosis and therapy related to bacteremia, nosocomial pneumonia, skin and soft tissue infections, infections by Clostridioides difficile, mycobacterial infections and invasive fungal infections. This year entailed a significant step forward in the indisputable value of the health care stewardship programs.
Analysis of the Strong and Weak Monotonic External Stability of the Resonance in a Perturbed Dynamical System
Authors: Lyubimov Vladislav V.
Published: October 2021

A perturbed dynamical system involving two ordinary differential equations is under review. Whereupon, the differential equation for determining the fast phase contains the ratio of the two frequencies. When these frequencies coincide for a long time, a resonance is implemented in this system. The aim of this paper is to obtain the conditions of monotonic external stability and instability of this resonance. The sufficient conditions for the external stability and instability of the resonance defined in this paper assume that the signs of the analyzed derivatives remain unchanged in the non-resonant section of the change in the independent variable. This paper gives a new classification of the phenomenon of external stability of resonance, which includes weak, linear, and strong stability. It should be noted that the conditions of monotonic external stability and instability of the resonance presented in this paper can be used in various scientific and technological problems, in which resonances are observed. Particularly, the concluding part of the paper considers the application of the results obtained within the framework of the problem of the perturbed motion of a rigid body relative to a fixed point.
