The airflow characteristics around and within an isolated gable roof building was investigated using CFD simulation based on steady RANS computation. Model validation and grid sensitivity analysis were conducted to ensure the reliability of the results. Three different roof pitches of gable roof namely 15º, 25º and 35º were considered in this study. The model validation results show well agreement with those of Tominaga et al. (2015). In general, the streamline and pressure coefficient were found to be significantly depending on the roof pitch. The streamline shows the velocity at the inlet opening and outlet opening increased as the roof pitch increase except the roof opening outlet increased between 15º and 25º then decreased between 25º and 35º. The spatial distribution of pressure coefficient at the windward side and the interior of the building decreased as the roof pitch increased. The difference in the flow fields of 25º and 35º roof pitch is large with the presence of window and roof opening relative to the difference between 15º and 25º roof pitch. In terms of spatial distribution of pressure coefficient and streamline, steeper roof pitch is more preferable.

Abstract- The study of face recognition is one of the areas of computer vision that requires significant research at the moment. Numerous researchers have conducted studies on facial image recognition using a variety of techniques or methods to achieve the highest level of accuracy possible when recognizing a person's face from existing images. However, recognizing the image of a human face is not easy for a computer. As a result, several approaches were taken to resolve this issue. This study compares two (two) machine learning algorithms for facial image recognition to determine which algorithm has the highest level of accuracy, precision, recall, and AUC. The comparison is carried out in the following steps: image acquisition, preprocessing, feature extraction, face classification, training, and testing. Based on the stages and experiments conducted on public image datasets, it is concluded that the SVM algorithm, on average, has a higher level of accuracy, precision, and recall than the k-NN algorithm when the dataset proportion is 90:10. While the k-NN algorithm has the highest similarity in terms of accuracy, precision, and recall at 80%: 20% and 70%: 30% of 99.20. However, for the highest AUC percentage level, the k-NN algorithm outperforms SVM at a dataset proportion of 80%: 20% at 100%.
An Analysis of Grammatical Errors Made by Students in Writing Descriptive Text at The Third Year Students of English State Islamic University Imam Bonjol Padang
Authors: Christina Dian , Rasmita Rasmita
Published: November 2021

The students usually make error on the use of grammar when they produce an English writing, also in writing descriptive text.

It is due to the difference between Indonesia and English grammatical system. If the students are not able to use those aspects correctly, it would be worried that their writing which is good content and organization would not give good sense because the readers misunderstand the message conveyed.

The purpose of this study was to describe types of grammar errors made by the third year students in paragraph writing.

The population of this research was 68 students of the third year students of English State Islamic University Imam Bonjol Padang, which were divided into two classes: class A and B. The sample was 30 students by using cluster random sampling.

This research was done by giving some topics and students had to choose one of the topics given such as “My Daily Activities”, “My Favorite Lecturer”, and “My Best Friend in this Semester”. The researcher uses qualitative method in order to obtain valid findings from 30 students of third year students of English.

Based on the error analysis conducted, the researcher found that errors regarding sentence structure are the most dominant errors, with the biggest number of errors are in verb and verb groups with the biggest number of errors are in addition verb (64,10%).

Then, it is followed by errors regarding nominal with the biggest number of errors are in inappropriate addition of nominal (35,90%). Last, the errors regarding pronoun with the biggest number of errors are in inappropriate selection pronoun (24,59%).

The findings show that the students have difficulties in using correct sentence structure, especially in omission verb. This problem may occur due to their lack understanding of grammatical rules.
State Law, Dispute Processing, and Legal Pluralism: Unspoken Dialogues from Rural India, By Kalindi Kokal, London: Routledge, 2020, 218 pp.
Authors: Silipigni Daniela
Published: November 2021

This book review discusses Kokal’s central points in State Law, Dispute Processing, and Legal Pluralism: Unspoken Dialogues from Rural India. Within the review, Kokal’s arguments of legal pluralism are pointed out and linked back to theories related to this field, such as Ehrlich’s theory of living law and Luhmann’s systems theory. The review explores Kokal’s idea of parallel legal systems being interconnected and operating at the same time. The review further sets forward the importance of Kokal’s work as providing an enlightening perspective to the socio-legal discussion of what is law and if we should conceptualise it in terms of state law or adopt a more bottom-up approach to the issue, as Kokal did in her own work.
Realización múltiple: Una crítica del argumento selectivo
Authors: Ríos Diego
Published: November 2021

El presente trabajo es una crítica del argumento selectivo con el que se ha buscado justificar la realización múltiple. Nuestra investigación se desarrolla en tres etapas: primero, se presenta un problema; luego, se describe la pretendida solución selectiva al mismo; finalmente, se critica tal solución. El problema consiste en explicar cómo realizadores que carecen de propiedades comunes producen efectos uniformes. La solución consiste en identificar un mecanismo selectivo que retiene aquellos realizadores que, a pesar de carecer de una estructura física común, son capaces de producir los mismos efectos. La crítica de dicha solución sostiene que la selección es impotente para explicar la realización múltiple por al menos dos razones. En primer lugar, por cuanto la existencia de realización múltiple supone una variación que es exógena al proceso selectivo. Y en segundo lugar, por cuanto la selección, lejos de promover variación al nivel de los realizadores, tiende a eliminarla. Los defensores del modelo selectivo identificaron correctamente un problema, pero fracasaron en mostrar que la selección pueda contribuir a su solución.
La noción de naturaleza en Aristóteles en el marco de sus críticas a Platón
Authors: Di Camillo Silvana Gabriela
Published: November 2021

En este trabajo, me propongo explicitar la noción aristotélica de naturaleza en el marco de sus críticas a Platón. En primer lugar, examinaré muy brevemente la propuesta de Platón en el Fedón y las críticas de Aristóteles a las Ideas como causas en Metafísica I 9; en segundo lugar, analizaré la definición de phýsis en Física II 1 como principio inmanente de movimiento; finalmente, intentaré mostrar cómo esa noción puede comprenderse mejor en el marco de la reapropiación y crítica de Platón, no solo por su característica inmanencia sino también por su eternidad a través de la generación natural. La phýsis, en Aristóteles, permite dar cuenta tanto de las propiedades esenciales cuanto de los procesos que experimentan los entes naturales.
El “regreso a la historia” y la pólis en el curso de Heidegger De la esencia de la verdad (1931-1932)
Authors: Rossi Luis Alejandro
Published: November 2021

El artículo se propone mostrar que el interés de Heidegger por pólis como concepto está ligado a una reformulación de la problemática de la intersubjetividad presentada en Ser y tiempo. Exponemos la relación entre el existenciario “ser uno con otro” (Miteinandersein) y “pólis”, con el fin de mostrar que con este concepto Heidegger designa la comunidad propiamencionada en el § 74 de Ser y tiempo, lo que implica que la temática ligada a la pólis tiene un sentido político en su pensamiento ya hacia 1931. La hipótesis es que la utilización de pólis como concepto está asociada en primer lugar a una radicalización política en direcciónal nacionalismo völkisch por parte de Heidegger.

В умовах Операції Об’єднаних Сил на сході України кожен воїн повинен бути забезпе- чений усім найнеобхіднішим для ведення бойових дій у складних умовах. Високоякісна військова форма відноситься в речовому забезпеченні до предметів першої необхідності. Тому одяг спеціального при- значення для військовослужбовців займає важливу нішу на українському ринку текстильних матері- алів та одягу й вимагає глибокого вивчення вимог до нього та визначення напрямів удосконалення. Тема є актуальною, має вагоме значення, тому що камуфляжний спецодяг – один із найважливіших чинників бойової готовності й виживання. Він використовується для захисту тіла від несприятливих впливів зовнішнього середовища: холоду, надмірної сонячної радіації, вітру, дощу та снігу, від меха- нічних ушкоджень, від пилу, бруду й укусів різних комах. Польова форма одягу повинна полегшувати бойову діяльність воїнів: маскувати їх на місцевості, бути зручною при обслуговуванні бойової техніки й озброєння, не заважати при подоланні перешкод, у тому числі й водних, лісистих, болотистих місць тощо. З естетичної точки зору військовий одяг прикрашає людину й дає можливість розпізнавати військовослужбовців служб, а також за їхніми військовими званнями. Однак найважливіше значення одягу полягає в зниженні втрат тепла організмом людини та забезпеченні найсприятливіших умов для підтримки температури тіла на постійному рівні. Одяг закриває більше як 80% поверхні тіла людини. З його допомогою навколо тіла утворюється штучний клімат (мікроклімат), який повинен бути най- більш сприятливим (комфортним). У сучасних умовах ведуться пошуки нових способів і форм матері- ального забезпечення військ на рівні достатньої комфортності для військовослужбовців ЗС України.

Важлива глобальна проблема XXI століття – безпека продуктів харчування. Сьогодні в умовах загрози швидкого поширення коронавірусу в Україні та світі питання продовольчої безпеки як ніколи є пріоритетним. У статті проаналізовано проблеми у сфері продовольчої безпеки в умовах пандемії коронавірусу. Зокрема, розглянуто основні проблеми, до яких призвела пандемія, зменшення об’ємів загального постачання продуктів харчування, брак сезонних робітників-мігрантів, закриття багатьох підприємств, шкіл та інших закладів освіти, а також обмеження щодо подорожей і соціаль- них зборів, зниження споживчих настроїв, зупинка декількох галузей – роздрібної торгівлі, готельного й ресторанного бізнесу, авіаперевезень, зменшення обсягів надходжень до бюджету, замороження інвес- тицій і виробничих ланцюжків українськими компаніями. Автор обґрунтовано показує вплив якості й доступності харчових продуктів на рівень життя, соціальну активність людини, на демографічний аспект її існування. Проаналізована економічна доступність продовольства України у 2016–2020 рр. Досліджені проблеми привертають увагу науковців і суспільства з огляду на необхідність реагування на виклики, зумовлені коронавірусною пандемією в продовольчій галузі. Доведено необхідність упрова- дження інноваційних технологій для підтримки харчової галузі та мінімізації ризиків продовольчої без- пеки. Описані в праці проблеми підштовхують наголосити на необхідності реагування суспільства на виклики, спричинені пандемією в продовольчій сфері, і стимулюють товаровиробників упроваджувати інновації науки й технологій для підтримки харчової галузі.

Authors: Лозова Т. М.
Published: November 2021

У статті наведено результати дослідження стійкості молочного жиру до автоокис- нення. Розглянуто можливість поліпшення зберігання цього жиру у спосіб сповільнення процесів окис- нення шляхом використання натуральних добавок-антиоксидантів рослинного походження. Наведено результати досліджень вчених, які займаються проблемою пошуку антиоксидантів. Зазначено, що застосування антиоксидантів має ґрунтуватися на лабораторному вивченні специфіки та особливос- тей природи жиру, його складу. Важливе значення відводиться контролю ступеня окиснення жиру. Метою статті є встановлення антиоксидантних властивостей добавок на рослинній основі з метою виявлення можливості подовжити тривалість збереження молочного жиру, а отже, продуктів із його вмістом. Автором статті показано позитивну дію натуральних антиоксидантів стосовно збе- реження якості молочного жиру. Продемонстровано, що додавання до складу молочного жиру рос- линних добавок у різних концентраціях (% до маси жиру) сприяє помітному сповільненню утворення й накопичення продуктів глибокого окиснення та збереженню його якості. Досліджено антиоксидант- ний вплив таких добавок на основі лікарсько-технічної сировини, як звіробій звичайний, квіти бузини чорної, вільха чорна. Доведено, що застосування зазначених добавок у концентрації 0,2% до маси жиру сприяє сповільненню накопичення вторинних продуктів окиснення в 1,7–2,3 раза. Вивчено також антиоксидантний ефект рослинних добавок плодів черемхи, перстачу прямостоячого і материнки звичайної в концентрації 0,1 і 0,2%. Застосування цих добавок у концентрації 0,2% виявляє вищу дію порівняно з концентрацією 0,1% приблизно на 30%. Їхнє використання обмежує утворення вторинних продуктів окиснення до 1,9 раза. Встановлена антиоксидантна дія досліджених рослинних добавок на молочному жирі обґрунтовується вмістом цінних біологічних сполук, таких як біофлавоноїди, антоці- ани, хлорогенової, аскорбінової кислот тощо.

Aim: To develop tables to assess the physical development of high schoolers based on the interaction of total physical dimensions.
materials and methods: To achieve this goal, we studied the indicators of body length, body weight and chest circumference of 7-17 years old boys (n=1111) and girls (n=1133) of secondary schools in Kyiv (Ukraine). Multiple correlation was used to calculate the interaction of indicators of total physical dimensions, and multiple regression was used to develop gender and age standards of physical development of high schoolers.
Results: The tables to assess physical development of high schoolers of a certain gender and age have been developed. The tables contain body length in vertical direction and body weight or chest circumference in horizontal direction, depending on what is needed for determination: the proper values of CC or body weight. The quantitative characteristics of high schoolers with good, excessive, below average and low levels of physical development are presented.
Conclusions: Rational organization of physical training of high schoolers is impossible without objective testing of the level of their physical development. Timely corresponding testing is a guarantee in preventing physical strains and health problems.

Aim: To study the impact of small doses of radiation pollution of environment on the physical development and health of students from different areas of residence.
materials and methods: The study was conducted at Polissya National University (Zhytomyr, Ukraine) during 2012-2020. 647 students of different specialties in the age of 17-23 were interviewed about the use of preventive measures to eliminate the consequences of the Chernobyl Nuclear Power Plant (CNPP) accident in 1986 and other factors of radiation pollution of environment. In addition, 127 students who were born, lived for some time or periodically lived in the area of low doses of radioactive contamination (58 males and 69 females) and 238 students who lived in the clean area from radioactive contamination (113 males and 125 females) were interviewed to compare the samples.
Results: The comparative analysis of the students’ physical development from different areas of residence showed that the students from the clean area have better indicators of average body height, body weight, Erisman index with no significant differences (P>0.05). Significant differences were revealed in the indicators of the circumference of the chest and the dynamometry of the hand (P<0.05-0.01).
Conclusions: It was established that long-term residence in the area with low doses of radioactive contamination has a negative impact on the physical development and health of the students. The students who have lived for a long time in the area of radioactive contamination more often suffer from a disease, miss classes and get tired faster during physical education sessions. It was clarified that the majority of the students are not involved in health preservation activities, but only in cases when they face significant health problems associated with the need to see a doctor, disability, etc.

Published: November 2021

The aim: To determine the prevalence rate of Staphylococcus aureus infection among children with Cystic Fibrosis in the Dnieper region, to provide microbiological characteristics of the isolates and to elevate their susceptibility to antimicrobials.
Materials and methods: Sputum, tracheobronchial lavage waters and/ or deep smear from the posterior pharyngeal wall were taken from children with genetically confirmed Cystic Fibrosis. Bacteriological method was the main. The first screening for small colony variants of Staphylococcus aureus was carried out after 48 hours of incubation. The antimicrobials susceptibility testing was determined by disk-diffusion method according to the EUCAST 2019. Microsoft Office Excel 2010 was used for statistical data processing.
Results: Twenty one children were enrolled in the survey. The culture of Staphylococcus spp. was obtained from all patients with 40.8% positive for Staphylococcus aureus. Small colony variants appeared with the prevalence rate 21.6% after 48 hours of incubation. The frequency of associations between Staphylococcus aureus with auxotroph phenotype with the presence of Pseudomonas aeruginosa was significantly higher than with wild-type group. The 3d-generation aminoglycosides, the 3d-generation fluoroquinolones, linezolid, rifampicin and tetracyclines showed the best antimicrobial activity, however, resistance to cefoxitin and gentamicin was significantly higher in auxotroph-modified group.
Conclusions: Infection Staphylococcus aureus is common among children. The appearance of auxotrophs registered after treatment with aminoglycosides and/ or co-trimoxazole and co-infection Pseudomonas aeruginosa. Isolates of Staphylococcus aureus showed good chemotherapeutic sensitivity, but tendency in increasing resistance registered for auxotroph-modified phenotype.

The aim: In this study, we present a sub-analysis of physical functionality in sufferers of mild knee osteoarthritis (OA) following a clinical assessment of a novel nutraceutical supplement Tregocel® complementary to standard treatment.
Materials and methods: We evaluated the results of a multicenter, open-label, single-arm efficacy and safety evaluation of a polyherbal nutraceutical, performed in subjects with symptomatic, mild knee OA (n = 107, 59.7 ± 10.8 yrs, 68.2% female) over 36 weeks. Physical function was assessed using a standardized walking challenge (6-min walk test), combined with WOMAC indices and leg flexion measurements. Sub-analysis was performed using a linear mixed model that tracked changes in the walking challenge outcomes over time, adjusted for age, gender, and OA duration.
Results: Walking distance was significantly improved with the duration of nutraceutical use, increasing by 0.72 m (95% CI: 0.56, 0.88) per week of product administration. Similarly, there were significant decreases in WOMAC indices per week for stiffness (-1.6, 95% CI: -1.8, 1.4), daily functioning (-13.5, 95% CI: 14.9, 11.9) and global outcome (-19.2, 95% CI -21.3 – -17.1). Furthermore, supine heel-to-high flexion distance was improved relative to the duration of nutraceutical use.
Conclusions: The use of a polyherbal nutraceutical resulted in clinical improvements in several indices of physical functioning in mild knee OA suffers. Trial registration: NCT03636035

The aim is to substantiate morphologically the resection boundaries of the salivary gland tissue in the surgical treatment of patients with pleomorphic adenoma of different histological variants.
Materials and methods: The study used autopsy, surgical and biopsy material, divided into 2 groups. Group 1 included autopsy material (n=6), represented by tissue fragments of the parotid salivary gland, in which macroscopic and microscopic examination did not reveal any general pathological processes. Group 2 included surgical and biopsy material from 30 patients, represented by pleomorphic adenomas with adjacent tissue of the salivary gland at a distance of 0.5 cm and 1.0 cm. Histological, morphometric and statistical research methods were used.
Results: The morphological features of the salivary gland tissue which was adjacent to the pleomorphic adenoma at a distance of 1.0 cm, practically corresponded to the physiological norm. However, the tissue of the salivary gland, bordering the tumor at a distance of 0.5 cm, was characterized by pronounced changes. These changes were: violation of the ratio of the specific volumes of the parenchyma and stroma; atrophy of the terminal sections and ducts with cystic expansion of some ducts; thickening of the secretion and formation of calculi in the lumen of some ducts; atrophic and alterative changes in the epithelial lining the terminal sections and ducts; sclerosis and lipomatosis, areas with hyalinosis and dystrophic calcification in the stroma; hemodynamic disturbances in the stroma with a decrease in the number of vessels; pronounced focal or diffuse immune infiltration in the stroma in some areas with the lymphoid follicles formation.
Conclusion: The comprehensive study has confirmed that removal of the tumor with the adjacent tissue of the salivary gland at a distance of 1.0 cm in patients with pleomorphic adenoma of various histological variants is the most justified from the morphological point of view.

The aim is to study the dynamics of lipid peroxidation and antioxidant protection in the blood of patients with generalized periodontitis accompanied by normo-, hyper- and hyporeactivity of the body after patch surgery.
Materials and methods: 216 people aged 45 between 55 years with a diagnosis of generalized periodontitis of II, III degree of severity, chronic course were examined. Depending on the condition of reactivity of the organism, patients were divided into three groups: the first consisted of people with normoreaction; the second included patients with hyperreaction; the third group was made up by people with hyporeaction. Patients after initial therapy, underwent patch surgery. Blood sampling was performed after surgery on the 1st, 2nd, 4th, 6th and 9th day. The content of diene conjugates, malonic dialdehyde and peroxide hemolysis of erythrocytes, superoxide dismutase activity, catalase, and total antioxidant activity was determined by the biochemical method.
Results: Normoreaction was characterized by two-phase moderate activation of lipid peroxidation with maxima on the 1st and 6th day against the normalization of the balance of oxidative systems by the end of observations. For hyperreaction pronounced activation of lipid peroxidation (significant increase in the content of diene conjugates and malonic dialdehyde with a maximum on the 1st day) accompanied by depletion of antioxidant protection activity was typical. Hyporeaction was characterized by slow activation of lipid peroxidation (increase in diene conjugates and malonic dialdehyde with a maximum on the 4th day) accompanied by insufficient activity of antioxidant protection.
Conclusion: Correction of altered parameters in patients with generalized periodontitis accompanied by impaired (hyper- and hypo-) reactivity of the body with bringing them to values of normoreactivity is considered to be a condition for optimizing mucosal wound healing after surgery and further stabilization of the periodontal tissues.

In this paper, we present a simple design of a feed network for the antenna to achieve a lower side lobe level. Side Lobe Levels (SLL) are critical issues in the detection of an object. Higher side lobe levels can increase the false detection of objects in an autonomous vehicle system. The array is designed and simulated for four different frequencies, one at a time to make it a scalable design. The chosen frequencies are 10 GHz, 15 GHz, 20 GHz, and 24 GHz. The feed network design consists of eight patch elements with an equal power divider and CST studio software is used for simulations. From simulation results, it can be observed that VSWR is equal to 1.26, 1.16, 1.62, and 1.05 at respective frequencies. So, the radiation efficiency can be achieved as -1.14 dB, -0.92 dB, -0.46 dB, -0.41 dB. The results substantiate that proposed design can reduce the SLL more than -24.5 dB in the elevation plane and also it is greater than 14.4 dB at all the aforementioned frequencies.

Air pollution in India poses a big threat to human lives. In 2017, 77% of population of India was subjected to PM2.5 (Particulate Matter) exposure resulting in mortality of 6.7 lakh throughout the country. In this study, Long Short-Term Memory (LSTM) model, a powerful deep learning technique is applied for PM2.5 prediction. Three variants of LSTM model, LSTM for regression, LSTM for regression using window and LSTM for regression with time steps are developed to predict PM2.5 concentration in India. The metrics used to evaluate the performance of the predictive models are root mean square error (RMSE) and coefficient of determination (R2). The models are applied to continuous ambient air quality data collected from 14 stations in India, for the period from May 01, 2019 to April 30, 2020 at an interval of every 15 minutes. The optimal results are obtained from the models with the tuned parameters of 64 epochs and batch size of 32. All the three variants of LSTM model performed equally well in predicting PM2.5 concentration. The experimental results revealed that the value of R2 is maintained at 0.9 consistently for all the variants of LSTM model. The low values of RMSE and high values of R2 proved the reliability of the model. Thus, the proposed model gives awareness about the air pollution level in India and alerts the society to take precautionary steps to save their lives. Further the urban planners can have idea of the pollution levels for their planning and decision making.

Nowadays, Engineers are actively seeking to improve construction materials and properties. In that, the usage of the castellated beam is become very popular due to its advantageous structural applications. In existing researches are described the presence of large openings in the web that creates different mechanical behaviour compared to strong web beams. While it does not deal with the behaviour of the shear strength performances of the castellated beam, which is due to the limitations on maximum allowable deflections by welding stiffeners. Therefore, this research analysis intends on augmentation of shear strength in castellated beam. Hence, the work incorporates shear stiffeners along with the web opening of the web adjacent to the shear region. Consequently, it leads to increase the shear strength of the castellated beam chassis with regard to cyclic loading and also efficiently reduce the deflection. In order to improve the behaviour of the castellated chassis beam, the study investigation providing the diagonal stiffeners on the web opening with the shear zone and thus compared to without stiffeners and vertical stiffeners. At last castellated beam and deflection effects with increased depth of web openings are analysed with the aid of Finite Element Analysis software ANSYS 16.0. From the experimental findings, the paper achieves the maximum deflection of forwarding and reverse cyclic loading is 7.7mm and 7.29mm respectively. This demonstrates the efficacy and the confines of the assorted studies of stiffening solutions.

In this study, numerical simulations were carried out to explore the response of the reinforced honeycomb sandwich structure with varying cell size (7, 10 and 15 mm), node length (25, 37.5 and 50 mm) and cell wall thickness (0.1, 0.2, 0.3 and 0.4 mm). The honeycomb structure made of aluminum alloy 8011 were subjected to low intensity blast loads by varying mass of TNT (10 g, 15 g, 20 g and 25 g) and standoff distance (200 mm, 250 mm and 300 mm). Commercial finite element code LS-DYNA was employed to carry out numerical simulations for both conventional and reinforced honeycomb sandwich structure keeping identical geometrical and blast load parameters. The deformation of the back face sheet was a major parameter to establish blast resistance of the core. Failure mechanisms of reinforced honeycomb was characterized as fully folded region, partially folded region, and clamped region. Reinforced honeycomb sandwich outperformed the conventional honeycomb sandwich structure of identical geometry parameters under similar blast loads. Increase in cell-wall thickness and node length enhanced the blast resistance whereas, increment in cell size reduced the blast resistance of the reinforced honeycomb sandwich structure.
