Introduction. Plant oils are valued ingredients of the oil phase of cosmetics. Argan oil is a semi-drying oil and is composed mainly of unsaturated fatty acids. It also contains saturated fatty acids and antioxidants such as tocopherols and polyphenols, among others. Evening primrose oil is rich in UFA and GLA. It is also a source of vitamins, zinc, calcium, magnesium and selenium. Skin has a protective role in the human body. The quality of its function depends on the level of hydration, among other aspects. Appropriate hydration is achieved with suitable skin care products, including natural oil-based emulsions. Aim. The aim of the study was to compare the efficacy of skin hydration for two cosmetic products: argan oil cream and evening primrose oil cream. Material and methods. The studied cosmetic products were assessed in terms of their sensory properties and qualitative composition based on information published at https://ec.europa.eu/growth/sectors/cosmetics/cosing_pl and guidelines included in the Regulation No 1223/2009. Corneometry was used to assess skin hydration and videodermatoscopy was performed. A tester applied a cream on herself for three weeks. Corneometry was performed once a week and videodermatoscopy was performed every day. Results. Corneometry assessment of evening primrose oil cream and argan oil cream indicated a significant increase in skin hydration following the use of the former. The hydration level of the skin of the hands was much lower than that of the face. The left side of the face was less hydrated than the right one. The hydration levels for both hands before and after the study were similar. Conclusions. The study demonstrated a significant impact of the cream used on the level of skin hydration. The evening primrose oil cream turned out to have strong hydrating properties. Despite unfavourable rheological characteristics, the cream did not display comedogenicity.

The issue of uterine bleeding is important not only in gynecology, but also in family medicine. Patients with abnormal uterine bleeding often report to family doctor's outpatient clinics. However, such situations usually require further specialist gynecological care – abnormal uterine bleeding is the most common cause of hospitalization of women in gynecological wards. These patients need detailed diagnosis, and many of them require hospitalization and specialist treatment. The problem of heavy uterine bleeding also affects patients of developmental age, with juvenile bleeding (metrorrhagia iuvenilis) being a particular issue here. This is acyclic bleeding in girls that lasts over 10 days up to 3 months. These bleeds are very heavy and prone to relapse. They can cause anemia. Severe cases and other hemorrhages in gynecology can be life-threatening. Most often pathological changes in the uterine cavity may manifest as abnormal bleeding concern menstruating patients ar reproductive age, as well as those in the peri- and postmenopausal period. However, juvenile bleeding is an important problem in gynecology

Methods Sixteen subjects with UCLP, aged between 7 and 14 years (mean age 10.9 ± 2.7 years) consecutively treated with bonded maxillary expander and hybrid activation were included. The dental casts before and after treatment were digitalized using a 3Shape scanner. Intercanine, interpremolar and intermolar widths (at cusp and gingival levels) and arch perimeters were measured. The significance level for statistical analyses was set as p < 0.05. Results The total treatment time using the hybrid expansion protocol lasted 12 ± 1.9 months while the active expansion time lasted 4 ± 0.2 months. Patients with UCLP showed significant differences in all transverse upper arch dimensions both at cusp and gingival level. Conclusion The use of a bonded maxillary expander with a hybrid activation protocol during growth may be efficient to improve all transverse upper arch widths in patients affected by UCLP

Authors: Ferral Hector , Fimmel Claus J. , Sonnenberg Amnon , Alonzo Marc J. , Aquisto Thomas M.
Published: April 2021

Objectives:

Measurement of hepatic vein pressures is the accepted gold standard for the evaluation of portal hypertension. This study was conducted to evaluate the correlation between hepatic vein pressure measurements and histologic findings from transjugular liver biopsies. The hypothesis was that higher hepatic venous pressure gradients would correlate with a histologic diagnosis of cirrhosis.

Material and Methods:

We identified all patients who underwent transjugular liver biopsies at our institution between January 2015 and December 2019. Of these, 178 patients who had undergone hemodynamic evaluations during the biopsy procedure were included in the study. Demographic information and laboratory data were extracted from the patients’ electronic medical records. The hepatic vein pressure gradient (HVPG) was determined by subtracting the free hepatic venous pressure from the wedged hepatic venous pressure (WHVP), and the portosystemic gradient (PSG) was determined by subtracting the right atrial pressure from the WHVP. HVPG and PSG were compared by linear regression analysis and by calculating their receiver operating characteristics (ROC).

Results:

HVPG and PSG measurements were significantly associated with cirrhosis, with area under the ROC curve of 0.79 and 0.78, respectively. At the optimal cutoff of 9 mmHg, sensitivity and specificity for HVPG were 71% and 83% for HVPG and 67 % and 81% for PSG, respectively. No statistical difference was observed between the two measurements.

Conclusion:

A transhepatic venous pressure gradient above a cutoff of 9 mmHg is predictive of histologic cirrhosis, regardless of whether it is expressed as HVPG or PSG, with acceptable to excellent performance characteristics.
A Simple Theoretical Analysis of the Burn-out Times of an Isothermal Particle of Coal Char Under Air-Firing, Gasification and Oxyfuel Combustion in Fluidised Beds
Authors: Omojola Toyin
Published: April 2021

Coal combustion in air, gasification with carbon dioxide, and oxyfuel combustion in oxygen/carbon dioxide mixtures was studied at high process temperatures in a bubbling fluidised bed reactor where burning is controlled by external mass transfer conditions. Theoretical analysis of the burn-out times of an isothermal particle of coal char in air is provided for the case where a fraction of carbon monoxide is oxidized close to the char particle. Burn-out time equations are provided for the gasification of char in carbon dioxide. Both burn-out time equations are compared to analytical equations derived for the oxy-fuel combustion of char particles in oxygen/carbon dioxide mixtures. The results are particularly relevant for retrofitting existing bubbling fluidised bed reactors for clean energy generation to meet global warming targets.
Development of biometric systems for passenger identification based on noise-resistant coding means
Authors: Gladkikh A. A. , Volkov A. K. , Ulasyuk T. G.
Published: April 2021

The paper deals with the issues of using the biometric technologies to establish identity of a passenger. The purpose of the article is to analyze the techniques of enhancing reliability of various biometric identification facilities by means of using error correction codes. The basic elements and the principle of the classical biometric system functioning are presented. On the basis of the International Civil Aviation Organization (ICAO) recommendations, the procedure features of pattern recognition are presented. The versions to adopt the biometric passenger authentication procedures are under consideration. The conclusion is drawn that with the centralized biometric databases the issues of confidentiality and information security exist. The problems are characterized by the possibility of biometric images compromise, which can potentially lead to the loss of their confidentiality and the impossibility of their further usage for personal identification. The passenger authentication procedure involving the simultaneous use of biometric parameters and contact-free SMART cards seems more reliable. SMART cards are used for distributed storage of biometric and other additional data, thus neutralizing the disadvantages of access to the centralized databases. It is shown that the subsequent step in the development of this domain is the application of biometric cryptography proposing "linking" encryption keys and passwords with the biometric parameters of the subject. Consideration is given to the principle of "fuzzy extractor" operation as one of the variants for the "biometrics-code" converter. Feasibility and necessity of upgrading the means of noise-resistant coding in the systems being studied are shown. The use of permutation decoding data algorithms capable of adequately corresponding to the particular problems of biometric identification is proposed. On the basis of the results of optical communication channels statistical modeling, the necessary and sufficient conditions for application of the permutation decoding tools for binary codes are determined. The problem to minimize memory amount for the permutation decoder cognitive map due to the permutation orbits allocation and usage of the generated loops combinations as pointers of reference plane is solved. The resulting algorithm for finding a unique orbit number and its corresponding reference plane by means of receiver formation of arbitrary parameters permutation from the set of permissible permutations is proposed.

Glucose levels that accumulate in the blood can cause other organ disorders and even cause death. To prevent such occurrence, continuous and regular glucose measuring and monitoring is required for diabetes mellitus (DM) patients. Glucose measurement for DM patients are generally performed several times a day, so be required easy, harmless method of measuring the DM patients, and monitoring data are well recorded. Thus in this research, an android non-invasive glucose level system with wireless communication and automatic data storage on the phone’s memory was developed. The study was begun with the built of electronic and software systems as the central part of the measuring system. The electronic section consists of laser and light sensors that respond to a change in blood glucose (BG) levels, the microcontroller that controlled all of the measuring processes, and Bluetooth modules as transceiver on data communication of the android. The software section is built using an App Inventor developed by the Massachusetts Institute of Technology (MIT) to display and store data measurement on the mobile phone. The calibration process of light sensors is done with the standard tool and at last, the wireless communication systems testing and BG levels measurement. The result shows that 94 mg/dl of BG levels by standard tools equals 2.86 volts of voltage measured by the design system. The higher the BG level, the lower the voltage be. Increase the BG level causes the resistance between the transmitter and the receiver to raise and the voltage becomes low.

El objetivo del trabajo fue analizar cómo afronta América Latina a diferencia del resto del mundo la pandemia del Coronavirus COVID-19 y     consecuencias sanitarias ocasionan a la región. Tras la aparición en Asia del COVID-19, Europa y Estados Unidos hoy viven una expansión acelerada del virus y todo indica que la próxima región además de África podría ser América Latina. La pandemia golpea la región con escasas ventajas para enfrentar el virus, por un lado, en un apresurado intento de frenar la propagación ha tomado medidas radicales mucho antes que los norteamericanos y europeos. Este estudio demuestra que Latinoamérica posee un menor crecimiento económico por lo que afrontaría la pandemia con inferiores herramientas, principalmente con limitadas infraestructuras sanitarias y estancamiento económico además de frágiles gobiernos y con poca maniobra financiera para incrementar el gasto público. No obstante, los países del sur de América a diferencia del Caribe y Centroamérica tienen un periodo invernal y están por entrar hacia un periodo invernal lo cual en teoría favorece la expansión del virus.

Intercultural education in times of restricted travel: Lessons from the Gaza Strip
Authors: Imperiale Maria Grazia
Published: April 2021

This article draws upon a research project on intercultural language education conducted online between 2014 and 2017 with people living in the Gaza Strip (Palestine). Because the Gaza Strip has been under blockade since 2007, people cannot travel in and out freely. This context thus prompts educators and scholars to reflect on intercultural competence from a context of protracted crisis and of forced immobility. This study considers pre-service and in-service English teachers’ understandings of intercultural competence and how these educators encourage intercultural communicative competence (ICC) in their classrooms in the Gaza Strip, where neither teachers, nor students, may have travelled abroad or experienced a face-to-face intercultural encounter. Based on this analysis, this article argues that frameworks for intercultural education and ICC need to capture non-movement and the lack of face-to-face intercultural encounters as agentic in definitions of interculturality. In other words, ICC should be conceptualised in terms of the actual freedoms and opportunities that individuals have to develop and nurture it. In order to propose such a model, this article connects ICC with the capabilities approach (Nussbaum, 2011; Sen, 1999), the capability of mobility (de Haas, 2010), and with the capacity to aspire (Appadurai, 2004).

RESIDU ANTIBIOTIK PADA SUSU KAMBING PE YANG MENDERITA MASTITIS SUBKLINIS DI DESA AIKMUAL LOMBOK TENGAH
Authors: Iskandar Rodi
Published: April 2021

Subclinical mastitis is a disease that often occurs in Etawa (PE) crossbreed goat farms. Farmers in handling this disease usually use antibiotics, giving antibiotics that are not right or according to the procedure can cause residues. The presence of antibiotic residues in goat's milk can have an impact on human health such as poisoning, allergies, and microbiological disorders. This study aims to determine the incidence rate and find the presence of antibiotic residues in the milk of Etawa Peranakan goat who suffer from subclinical mastitis in Aikmual Village, Central Lombok Regency. Test results from 6 samples of etawa-crossed goat milk (PE) suffering from subclinical mastitis using the Bioassay Screening Test method showed negative results containing antibiotic residues. Negative results in the sample are marked by the absence of dead bacteria on paper discs that have been soaked with milk samples from goats that are positive for subclinical mastitis, this is evident from the absence of inhibitory zones formed. The negative effect of this milk sample is due to several possibilities, namely: The stopping period of the drug has been reached and the antibiotics used are in accordance with  the  dose. The duration of the presence of antibiotics in milk depends on several factors,  including: dose, method of administration and type of antibiotic. In  general,  it is applied  that the withdrawal time of narrow spectrum antibiotics is at least 5 days after treatment, for the type of antibiotics that can form a depot (broad spectrum) has a withdrawal time of 1 3 days

The remaining serum obtained was sent to BBVet Wates for CFT examination. The results obtained show negative results on both tests. But one of the samples with the code S9 had gone through an abortion. This might occur due to other factors such as genetic disorders, the presence of viruses such as BVD, toxic agents and live vaccines during pregnancy.
Do Students in Gifted Programs Perform Better? Linking Gifted Program Participation to Achievement and Nonachievement Outcomes
Authors: Redding Christopher , Grissom Jason A.
Published: April 2021

Growing concerns about inequitable access have made public investment in gifted programs controversial in many school districts, yet advocates maintain that gifted services provide necessary enrichment for exceptional students to succeed at school. We provide evidence on whether the typical gifted program indeed benefits elementary students’ achievement and nonachievement outcomes, using nationally representative data from the Early Childhood Longitudinal Study, 2010–2011 kindergarten cohort. Leveraging within-school and within-student comparisons, we find that participating in a school’s gifted program is associated with reading and mathematics achievement for the average student, although associations are small. We find no evidence of a relationship between gifted participation and student absences, reported engagement with school, or student mobility. Black and low-income students do not see the academic gains that their peers experience when receiving gifted services.

Authors: Milchakov Mikhail V.
Published: April 2021

Due to historical features and the heterogeneity of the economic landscape, the regions of Russia are

characterized by significant disparities in the level of socioeconomic development. In order to manage

regional development, a number of important strategic documents have been adopted, including the

Spatial Development Strategy. The tasks of supporting problem regions and developing the largest

agglomerations are articulated in these documents. In the context of the pandemic, new challenges

have emerged related to slowing economic growth and budget constraints. The article examines the

specifics of the formation of individual programs for the socioeconomic development of problem

regions, as well as the situation of cities with more than 1 million inhabitants during the pandemic. The

author presents proposals for improving the measures included in the Spatial Development Strategy

Dynamic multi-patch isogeometric analysis of planar Euler-Bernoulli beams
Authors: Vo Duy , Borković Aleksandar , Nanakorna Pruettha , Bui Tinh Quoc
Published: April 2021

This study presents a novel isogeometric Euler-Bernoulli beam formulation for in-plane dynamic analysis of multi-patch beam structures. The kinematic descriptions involve only displacements of the beam axis, which are approximated by non-uniform rational B-spline (NURBS) curves. Translational displacements of the control points are here considered as control variables. The motivation of this work is to propose a penalty-free method to handle in-plane dynamic analysis of multi-patch beam structures. A simple relation between cross-sectional rotations at the ends of the beams and control variables is derived, allowing the incorporation of the end rotations as degrees of freedom. This improved setting can straightforwardly tackle beam structures with many rigid multi-patch connections, a major challenging issue when using existing isogeometric Euler-Bernoulli beam formulations. Additionally, rotational boundary conditions are conveniently prescribed. Numerical examples with complicated beam structures such as circular arches and frames with kinks are considered to show the accuracy and performance of the developed formulation. The computed results are verified with those derived from the conventional finite element method, and the superior convergence properties of the proposed formulation are illustrated. We additionally discuss about the possible extension of the present approach to spatial beam structures.

Предложен и разработан метод описания спиральных структур разного уровня организации в белках. Метод позволяет охарактеризовать знак хиральности/спиральности и выполнить количественную оценку для α-спиралей, 310-спиралей и coiled-coil-суперспиралей, что существенно для развития разработанной ранее концепции о знакопеременных иерархиях хиральных структур в белках и нуклеиновых кислотах. Достаточным условием метода является взаимное расположение α-углеродов в спирали, что позволяет на порядок снизить количество обрабатываемой информации и является значительным преимуществом при обработке больших массивов данных.

В ходе полевых экспериментов на наземных позвоночных было замечено, что прямое нападение при взаимодействии хищника и жертвы может не только повлиять на динамику популяции, но и косвенно повлиять на страх хищника (ощущаемый жертвой) через химические и/или голосовые сигналы, может также снизить воспроизводство жертвы и изменить ее историю жизни. В настоящей работе исследовано влияние страха на жертву с помощью системы «хищник-жертва» Беддингтона-ДеАнгелиса, включающей убежище жертвы и наличие дополнительной пищи. Во-первых, обсуждена положительность и равномерная ограниченность решений, которые делают предлагаемую систему хорошо работающей. Вводятся критерии существования, анализ локальной и глобальной устойчивости всех состояний равновесия. Далее представлены условия возникновения транскритических бифуркаций. Кроме того, изучен устойчивый характер точки равновесия сосуществования для различных комбинаций факторов задержки; обнаружено, что непрерывное увеличение параметров задержки может переключить стабильность равновесия со стабильной спирали на стабильные колебания предельного цикла через сверхкритическую бифуркацию Хопфа. Для проверки аналитических результатов с помощью MATLAB было выполнено обширное численное моделирование. Численно влияние убежища добычи на выживание хищника было представлено с помощью введения дополнительной пищи.

Предложен метод оценки частотной модуляции электроэнцефалограммы на основе Фурье-фильтрации исходного сигнала в узких частотных диапазонах, с последующим расчетом периодов пик-пик как для максимумов, так и для минимумов восстановленного сигнала. Полученные последовательности обрабатывались с использованием преобразования Фурье. В качестве объектов исследования были использованы электроэнцефалограммы здоровых добровольцев, полученные в ходе фотостимуляции. В целом диапазон электроэнцефалограмм в 7-9 Гц продемонстрировал для затылочных отведений более выраженный феномен частотной модуляции, в отличие от диапазона 13-15 Гц. Выявлено практически полное отсутствие различий для относительных к общей мощности спектральных показателей влияний, модулирующих электроэнцефалограмму. Выявлено два типа частотной модуляции электроэнцефалограмм в исследуемых частотных диапазонах - первый не связан с частотами и характеризуется либо высоким, либо низким уровнем воздействия, второй имеет связь характера модуляции с «несущей» частотой сигнала.
МУЛЬТИФРАКТАЛЬНЫЙ И ВЕЙВЛЕТНЫЙ АНАЛИЗ ИЗМЕНЕНИЯ СТРУКТУРЫ ПАТТЕРНОВ НЕПРОИЗВОЛЬНЫХ КОЛЕБАНИЙ РУКИ ЧЕЛОВЕКА ПРИ БОЛЕЗНИ ПАРКИНСОНА

С помощью методов вейвлетного и мультифрактального анализа показано, что при двигательных нарушениях в структуре паттернов непроизвольных колебаний руки человека, возникающих в процессе выполнения им двигательной задачи, появляются перестройки, сопровождающиеся возникновением долговременных корреляций между последовательными значениями этих колебаний. Эти перестройки являются причиной значительного повышения амплитуды непроизвольных колебаний руки человека с болезнью Паркинсона, по сравнению с такими колебаниями руки здорового человека. Механизм возникновения коррелированной динамики связан с повышением вклада сильных флуктуаций последовательных значений непроизвольных колебаний. Уменьшение амплитуды этих колебаний и энергии их вейвлетного спектра на фоне приема антипаркинсонических препаратов сопровождается уменьшением долговременных корреляций и смещением мультифрактальных характеристик в диапазон, характерный для здорового человека.
