A dynamic knowledge base and its data compression with homomorphism
Authors: Qin Bin
Published: November 2021

In reality there are always a large number of complex massive databases. The notion of homomorphism may be a mathematical tool for studying data compression in knowledge bases. This paper investigates a knowledge base in dynamic environments and its data compression with homomorphism, where “dynamic” refers to the fact that the involved information systems need to be updated with time due to the inflow of new information. First, the relationships among knowledge bases, information systems and relation information systems are illustrated. Next, the idea of non-incremental algorithm for data compression with homomorphism and the concept of dynamic knowledge base are introduced. Two incremental algorithms for data compression with homomorphism in dynamic knowledge bases are presented. Finally, an experimental analysis is employed to demonstrate the applications of the non-incremental algorithm and the incremental algorithms for data compression when calculating the knowledge reduction of dynamic knowledge bases.

Published: November 2021

Since small objects occupy less pixels in the image and are difficult to recognize. Small object detection has always been a research difficulty in the field of computer vision. Aiming at the problems of low sensitivity and poor detection performance of YOLOv3 for small objects. AFYOLO, which is more sensitive to small objects detection was proposed in this paper. Firstly, the DenseNet module is introduced into the low-level layers of backbone to enhance the transmission ability of objects information. At the same time, a new mechanism combining channel attention and spatial attention is introduced to improve the feature extraction ability of the backbone. Secondly, a new feature pyramid network (FPN) is proposed to better obtain the features of small objects. Finally, ablation studies on ImageNet classification task and MS-COCO object detection task verify the effectiveness of the proposed attention module and FPN. The results on Wider Face datasets show that the AP of the proposed method is 11.89%higher than that of YOLOv3 and 8.59%higher than that of YOLOv4. All of results show that AFYOLO has better ability for small object detection.

Background: An elevation in iron levels, together with an accumulation of α-synuclein within the oligodendrocytes, are features of the rare atypical parkinsonian disorder, Multiple System Atrophy (MSA). We have previously tested the novel compound ATH434 (formally called PBT434) in preclinical models of Parkinson’s disease and shown that it is brain-penetrant, reduces iron accumulation and iron-mediated redox activity, provides neuroprotection, inhibits alpha synuclein aggregation and lowers the tissue levels of alpha synuclein. The compound was also well-tolerated in a first-in-human oral dosing study in healthy and older volunteers with a favorable, dose-dependent pharmacokinetic profile. Objective: To evaluate the efficacy of ATH434 in a mouse MSA model. Methods: The PLP-α-syn transgenic mouse overexpresses α-synuclein, demonstrates oligodendroglial pathology, and manifests motor and non-motor aspects of MSA. Animals were provided ATH434 (3, 10, or 30 mg/kg/day spiked into their food) or control food for 4 months starting at 12 months of age and were culled at 16 months. Western blot was used to assess oligomeric and urea soluble α-synuclein levels in brain homogenates, whilst stereology was used to quantitate the number of nigral neurons and glial cell inclusions (GCIs) present in the substantia nigra pars compacta. Results: ATH434 reduced oligomeric and urea soluble α-synuclein aggregation, reduced the number of GCIs, and preserved SNpc neurons. In vitro experiments suggest that ATH434 prevents the formation of toxic oligomeric “species of synuclein”. Conclusion: ATH434 is a promising small molecule drug candidate that has potential to move forward to trial for treating MSA.
Postural neurologic deficits after decompressive craniectomy: A case series of sinking skin flap syndrome in traumatic brain injury
Authors: Bateman Emma A. , VanderEnde Jordan , Sequeira Keith , MacKenzie Heather M.
Published: November 2021

BACKGROUND: Hemicraniectomy to manage raised intracranial pressure following traumatic brain injury (TBI) has improved survival but may increase the incidence of Sinking Skin Flap Syndrome (SSFS). SSFS is a clinical syndrome in which patients with craniectomy develop objective neurologic abnormalities due to the pressure of the atmosphere on the unprotected brain, often presenting with postural headaches and neurologic deficits that localize to the craniectomy site. Previously thought to be a rare complication of craniectomy after TBI, evidence suggests SSFS is under-recognized. OBJECTIVE: To describe the clinical and radiographic features leading to diagnosis and the impact of temporizing and definitive management of SSFS on outcomes in inpatients with moderate/severe TBI. METHODS: Two patients’ symptoms, qualitative behaviour observation, physical and cognitive outcome measures, and neuroimaging pre- and post-temporizing measures and cranioplasty are presented. RESULTS: Both patients demonstrated partial improvements with temporizing measures and substantial improvements in functional, cognitive, physical, and rehabilitation outcomes from the cranioplasty and resolution of SSFS. CONCLUSIONS: Rehabilitation care providers are critical to the timely diagnosis and management of SSFS, including the use of temporizing measures and advocacy for definitive treatment with cranioplasty. These cases highlight the diverse clinical presentations and importance of SSFS diagnosis to improve patient outcomes.

Published: November 2021

BACKGROUND: Assessing physical activity (PA) in people with multiple sclerosis (PwMS) is essential to follow-up the recommended PA level. The International Physical Activity Questionnaire (IPAQ) and the Incidental and Planned Exercise Questionnaire (IPEQ) have been widely used, but their validity has not been investigated previously in PwMS. OBJECTIVE: This study aimed to assess the convergent and criterion validity of the IPAQ and the IPEQ in PwMS. METHODS: 50 PwMS were asked to wear an Actigraph for seven days and to fill the IPAQ and IPEQ. Sedentary, moderate (MPA), vigorous (VPA) and moderate to vigorous PA (MVPA) levels were recorded. RESULTS: Significant correlations were found between sitting time as reported by IPAQ and sedentary time as recorded by Actigraph (r = 0.41, p = 0.003), VPA by IPAQ and VPA as recorded by Actigraph (r = 0.46, p = 0.001), and MVPA by IPAQ and MVPA by Actigraph (r = 0.36, p = 0.011). IPEQ showed poor both criterion and convergent validity when compared to the Actigraph. Both IPAQ and IPEQ overestimate the intensities of PA for all the derived parameters. CONCLUSIONS: Findings of this study are important as they suggest that IPAQ in particular had convergent validity when compared to Actigraph data, but still had the problem of overestimating PA levels.

Published: November 2021

BACKGROUND: Appropriate body image self-perceptions provide a good help to increase the feeling of personal well-being, thus having an important impact on health. Universities, having an important role in shaping of the future workers, represent an important setting to approach health issues. OBJECTIVE: This study determined to what extent different types of students in higher education (four categories of students were created: “self-secure”, “perfect”, “destructive” and “apologetic”) are likely to adopt different health risk behaviors. METHODS: A cross-sectional study in a sample of students from five European Universities in the 2016/2017 academic year was conducted. Based on the combination of body image perception and body mass index, four types of students were identified: “self-secure” (overweight students with a good self-esteem); “perfect” (underweight students with a good self-esteem); “destructive” (overweight students with a poor self-esteem); “apologetic” (underweight students with a poor self-esteem). RESULTS: The study reveals that the defined types of students differed in terms of risk behavior. When the control was included, the “self-secure” student type had a reduced likelihood of being on a diet (22.3%) and physically active (17.8%) than other students (p < 0.001). CONCLUSIONS: The results of this paper raise concerns about the future because the body dissatisfaction of the college student could be a big impact in long term whether at collective, personally or even professionally.
Self-employment, work and health: A critical narrative review
Authors: Khan Tauhid Hossain , MacEachen Ellen , Hopwood Pamela , Goyal Julia
Published: November 2021

BACKGROUND: Self-employment (SE) is a growing precarious and non-standard work arrangement internationally. Economically advanced countries that favor digital labor markets may be promoting the growth of a demographic of self-employed (SE’d) workers who are exposed to particular occupational diseases, sickness, and injury. However, little is known about how SE’d workers are supported when they are unable to work due to illness, injury, and disability. OBJECTIVE: Our objective was to critically review peer-reviewed literature focusing on advanced economies to understand how SE’d workers navigate, experience, or manage their injuries and illness when unable to work. METHODS: Using a critical interpretive lens, a systematic search was conducted of five databases. The search yielded 18 relevant articles, which were critically examined and synthesized. RESULTS: Five major themes emerged from the review: (i) conceptualizing SE; (ii) double-edged sword; (iii) dynamics of illness, injury, and disability; (iv) formal and informal health management support systems; and (v) occupational health services and rehabilitation. CONCLUSION: We find a lack of research distinguishing the work and health needs of different kinds of SE’d workers, taking into consideration class, gender, sector, and gig workers. Many articles noted poor social security system supports. Drawing on a social justice lens, we argue that SE’d workers make significant contributions to economies and are deserving of support from social security systems when ill or injured.
Getting back to work: Experiences of the individual placement and support model from those with mental health conditions, an interpretative phenomenological analysis
Authors: Raeside Claire , McQueen Jean
Published: November 2021

BACKGROUND: Evidence continues to build on the value of Individual Placement and Support (IPS), enabling those with long-term mental health conditions to find mainstream employment. Many of these individuals would like to work; however, unemployment for this population remains high. IPS research thus far has targeted the effectiveness of the model, with less emphasis on how individuals perceive and experience IPS and the return to work. OBJECTIVE: This study explores the barriers, enablers, meaning and personal experience of being supported to find work through IPS, for individuals with long-term mental health conditions. Findings based on lived experiences of nine participants from two Scottish centres running IPS, should be useful to enhance and develop services. METHODS: This study involves qualitative data collection, using semi-structured interviews and Interpretative Phenomenological Analysis (IPA). RESULTS: Transcript analysis revealed three master themes: 1) “Working is good for me”: positive aspects to working; 2) “Rome wasn’t built in a day”: time-unlimited supported journey and 3) “My inner critic”: negative aspects to working. Participants praised IPS for the on-going practical and emotional support in overcoming self-identified occupational barriers. CONCLUSION: Paid employment was greatly associated with financial freedom, social inclusion, increased self-esteem and alleviation of depressive symptoms. Participants described the person-centred, time-unlimited approach taken by the employment specialists (ESs) or occupational therapists (OTs), as the main enabler to maintaining paid employment. Barriers, such as anxiety and work-related stress were identified, however, participants felt supported to overcome some of these negative symptoms.
Mounting a smartphone on a steering-wheel to facilitate ease of visibility of the navigation screen: A systematic product design approach
Authors: Verma Indresh Kumar , Karmakar Sougata
Published: November 2021

BACKGROUND: Both professional and personal car drivers use smartphones as In-Vehicle Infotainment System (IVIS) and generally mount it wherever they feel convenient. Inappropriate or sub-optimal positioning of navigation devices increases off-road eye-glance duration and fixation frequency. OBJECTIVE: The current research aimed to develop a smartphone holding device to facilitate the mobile-phone’s easy mounting on the steering wheel’s hub, ensuring the screen’s visibility at a comfortable viewing angle in a vertical upright position irrespective of the steering wheel’s rotation. METHODS: A systematic product design methodology was adopted to develop the final product. The morphological chart was adopted for generating the different concepts of the smartphone mounting device. A Pugh chart was used for screening the various concepts generated in the previous step. Finally, a prototype of the selected best concept was made. User acceptance was assessed by taking feedback from users, and System Usability Scale (SUS) was used for usability evaluation. RESULTS: The developed innovative mounting device was light-weight and easy to use (SUS score 83.5). The final prototype was very effective in changing the angle of the smartphone to facilitate easy visibility at a comfortable viewing angle through the use of a ball and socket mechanism at the base. A ball bearing system was used in the mobile-phone holder for maintaining vertical stationary position during steering wheel rotation. CONCLUSION: As the device is useful for mounting the smartphone on the steering wheel’s hub, it might reduce driver distraction.
Revalidating U.S. Army soldiers’ perceptions of combat arms job tasks: Frequencies, importance and expectations of performance
Authors: Boye Michael W. , Cohen Bruce S. , Canino Maria C. , Foulis Stephen A. , Sharp Marilyn A.
Published: November 2021

BACKGROUND: In 2013 the U.S. Army began developing physical tests to predict a recruit’s ability to perform the critical physically demanding tasks (CPDTs) of combat arms jobs not previously open to women. OBJECTIVE: To revalidate 15 CPDTs chosen by subject matter experts (SMEs) and researchers through questionnaires pertaining to task performance frequency, perceived importance, and performance expectations. METHOD: Web-administered job analysis questionnaires were completed by 2,090 soldiers. Seventy-three percent ranged between 25–38 years of age, 66%were staff sergeants or above, and 73%were in service for 7 + years. RESULTS: Overall, the nine SME-endorsed CPDTs were conducted more frequently and rated as more important than the six tasks identified by researchers. Foot march, dragging a casualty to safety, and connecting a tow bar (vehicle transport) were identified as the combined most important, most frequently performed and highly expected CPDTs to be performed. The canonical correlation between task performance frequencies and ratings of task importance across all 15 CPDTs was 0.82 (p < 0.001). Expectations of task completion were strongly associated with more frequent task performance (Cramer’s Vs ranged 0.22 to 0.71; all p’s < 0.001), but not task importance (only four CPDTs at p < 0.05). CONCLUSION: This study revalidates the value of CPDTs chosen by SMEs and researchers. Soldier readiness should reflect tasks identified by incumbents as important to success (e.g., evacuating a casualty) be trained more often, whereas others classified as frequently performed, but less important (e.g., filling sandbags), be deemphasized while ensuring that standards are met.

Authors: Singh Kirtiman , Rathore Abhishek , Bhana Indu , Chourasiya Mahendra
Published: November 2021

Background and Aims: To evaluate the prevalence and clinical significance of carotid artery plaque, in patients with coronary artery disease.

Material and Methods: A total of 1000 patients with 40-80 years of age with coronary artery disease were enrolled. Carotid ultrasonography was performed in all these patients.

Results: Among 100 patients with carotid artery disease, 36 had a carotid plaque. In plaque-positive cases, a majority of patients were in a 50 – 60-year age group. Dyslipidemia was found to be the most common risk factor for carotid plaque. In 36 plaque-positive cases, 20 (56%) were having the plaque at the carotid bulb and 16 (44%) were having the plaque at the common carotid artery. Out of 36 cases, 16 (44%) were hyperechogenic, 8 (22%) were calcified, 6 (17%) were moderate echogenic, 6 (17%) were low echogenic.

Conclusion: High-resolution B-mode ultrasonography is a useful non-invasive method to evaluate carotid atherosclerosis. Carotid plaques of the common carotid artery are a surrogate marker of atherosclerosis and associated with cardiovascular events. Routine screening of patients with coronary artery disease may be considered.

Keywords: Carotid artery stenosis, coronary artery disease, cardiovascular events, atherosclerosis, carotid ultrasonography.

Authors: Chebochakov Ye. Ya. , Murtaev V. N.
Published: November 2021

Relevance. According to the conducted studies, it was found that the disadvantages of steppe nature management include water erosion, deflation and other adverse phenomena. Similar processes are taking place in Siberia. At present, the redevelopment of deposits is beginning and soil degradation is again manifested in the steppe regions of Khakassia. For the rational and efficient use of land resources, it is necessary to develop a technology for processing soil deposits in the arid steppe zone of the south of Central Siberia.Methods. The study of the efficiency of soil cultivation technologies for the erosional agroecological group of fallow lands was carried out in the arid steppe agrolandscape region of the Republic of Khakassia, located in the south of Central Siberia. Research for four years was carried out in the link of fodder crop rotation: a long-term (20–25 years) cereal-forb fallow — oats (corn) for green mass by the method of B.A. Dospekhov. When performing the work, statistical and graphical methods were used.Results. It is established that malicious perennial grasses and juvenile weeds grow on long-term fallow lands (20–25 years). High efficiency of complex application of herbicides of continuous action (Tornado 500, Octopus Extra) and intensive tillage was revealed. Tillage of a long-term deposit to a depth of 18–20 cm, disking, fine flatcutting treatment and spraying with herbicide reduces the number of perennial weeds by 2 times more compared to technologies, that include small treatments and herbicide application. In the arid steppe zone, the technology with tillage of a long-term deposit to a depth of 18–20 cm increases the productivity of the feed crop rotation link by an average of 25.3–33.7% compared to technological operations involving small-scale processing (12–14 cm and 14–16 cm).

Relevance. The article is devoted to the actual problem of the spring-summer seeding of winter rye on drained lands.Methods and results. The studies were carried out in 2017–2020 at the experimental site of VNIIMZ (Tver region), drained by a closed drain. The soil of the experimental site is sod-podzolic light loamy gleyic slightly acidic, the content of humus is 1.8–2.4%, exchangeable potassium and available phosphorus content is increased and high. In field experiments, the effectiveness of spring-summer sowing dates for winter rye in a fallow field of crop rotation was studied with a ridge belt-spread cultivation method. It has been established that under the conditions of the north-west of the Non-Chernozem zone winter rye with its spring-summer sowing can form practically the same yields as with the standard cultivation technology. On average over 4 years the biological yield of rye grain when grown after spring rape was 3.69 t/ha, and with spring-summer sowing in a fallow field and harvesting the next year — 3.70 t/ha. The leveling of the variants in terms of yield with a significant difference between them in the plant density occurred due to productive tillering. The coefficient of productive bushiness in the control was 1.4, and with spring-summer sowing — 2.3. Differences between the variants in the number of productive stems, the number of grains per ear, and the weight of 1000 grains on average over 4 years were insignificant. High efficiency of harrowing of spring-summer crops of rye was noted both in the sowing year (late August — early September) and in spring after overwintering. The preservation of plants improved, the number of productive stems increased by 14.3%, and the biological productivity of rye increased by 18.4%. The technology of cultivation of winter rye with spring-summer sowing can significantly reduce the amount of field work in the fallow field, eliminate the costs of plowing, cultivation, sowing, rapeseed, and reduce the total production costs for maintaining 1 hectare of a fallow field by 7–10 thousand rubles.

Published: November 2021

Cylindrical coaxial heaters are increasingly used in agricultural production. However, their widespread use is restrained by the fact that it is still necessary to supplement the calculation methodology, which would make it possible to take into account its geometric dimensions, dielectric and magnetic permeability, surface effect and proximity effect, uneven distribution of electric and magnetic fields along the heater, and a number of other factors when choosing the parameters of the heater. Such a task is relevant in the design of electric heaters for the production needs of dairy farms, taking into account what the methodology presented below has been developed. This technique gave a positive effect in relation to the development of an experimental electric pasteurizer.

En las últimas décadas ha ido aumentando la opción de alimentación vegetariana en la población general y también en la edad pediátrica. Esto nos ha enfrentado a numerosas preguntas respecto a los beneficios y riesgos que se pueden presentar por su implementación. La restricción de alimentos im- plica la potencial deficiencia de varios nutrientes, estableciéndose algunos de ellos como críticos para este período de desarrollo y rápido crecimiento, por lo que la inocuidad de las dietas vegetarianas no ha sido del todo establecida a nivel mundial. Los principales nutrientes críticos son hierro, zinc, calcio, vitamina B12 y ácidos grasos omega 3. Los grupos de mayor riesgo de presentar deficiencias nutricionales son lactantes, adolescentes, opciones vegetarianas más restrictivas y aquellos que no po- seen adecuada asesoría nutricional profesional. Es por estas razones que las dietas vegetarianas deben ser estrictamente supervisadas. Sociedades científicas como la americana, canadiense, italiana y britá- nica de nutrición reconocen las dietas vegetarianas como saludables en la edad pediátrica siempre que sean supervisadas por profesionales de salud idóneos.

Published: November 2021

Актуальним питанням харчової безпеки є створення харчових продуктів, що містять білок. Риба залишається одним із ключових джерел білків. У цій статті об’єктом дослі- дження є риба хек, яка шляхом інфрачервоного сушіння та подрібнення була перетво- рена на концентрат супу. Результати експерименту показали, що зі збільшенням відстані випромінення сенсорні властивості хека покращуються, але водночас збільшується три- валість сушіння. Зі зміною відстані випромінювання ступінь зміни тривалості сушіння нижчий, ніж ступінь зміни температури сушіння. У діапазоні температур від 55 °C до 65 °C вологість сухої основи хека зменшується з часом експоненційно. З підвищенням тем- ператури тривалість сушіння, яка забезпечує його безпечне зберігання, скорочується, і навпаки. Тому, щоб заощадити матеріальні ресурси та час, відстань випромінювання має бути зменшена відповідно до передумови забезпечення якості сушіння. На кінцевій стадії висушування велика кількість вільної води у хека виводиться за рахунок випаро- вування. Як наслідок – важко видалити внутрішню зв’язану воду та хімічну воду через ефект сушки, і крива сушіння поступово стає пологою. Нами представлено технологію приготування та рецептуру рибного супового концентрату. Відповідно до цієї технології, висушена риба подрібнюється до тонкого ступеня подрібнення і змішується з іншими рецептурними компонентами. Рецептура супового концентрату математично оптимі- зований. Було вибрано оптимальне співвідношення компонентів рецептури: 20 г порошку хека, 3 г солі, 0,7 г глутамату натрію, 0,5 г порошку імбиру, 4 г білого цукру, 0,5 г коньячної камеді, 0,9 г ксантанової камеді, 0,6 г гуарової камеді. Завдяки високій харчовій цінності риби хек отриманий продукт буде мати високий вміст білків, вітамінів А і D, кальцію, магнію, селену та інших життєво необхідних нутрієнтів. Суха порошкоподібна струк- тура робить його зручним для зберігання та транспортування.

Проведено аналіз сучасного стану водних та земельних ресурсів басейну річки Цир (зона Полісся, Волинська область, Камінь-Каширський район) з метою виявлення основних проблем їх раціонального використання та охорони в умовах зміни клімату. На основі проведеного гідрологічного, геологічного та гідрогеологічного аналізу сфор- мовано сучасні гідрографічні характеристики річки Цир. Аналіз даних показує, що на території басейну річки Цир розвинені процеси заболочення та підтоплення заплави річки, а також карстоутворення і розвіювання пісків еолових гряд і дюн. Майже всюди схили долини є слабо розчленованими, здебільшого відкритими, розораними, місцями залісненими. Переважають піщані або суглинисті ґрунти, рідше – супіщані або глинисто-піщані. Встановлено, що в межах басейну річки Цир розвинені процеси заболочення та підто- плення заплави річки. Деградація ґрунтів проявляється у вигляді вітрової ерозії та кар- стоутворення. Аналіз технічного стану Цирської осушувальної системи, магістральним каналом якої є річка Цир, вказує на те, що через незадовільний стан русла (заростання та замулення) річки Цир система не спроможна належним чином виконувати своє функціональне при- значення – відведення дренажного стоку та сезонне водорегулювання. Крім того, відсут- ність експлуатаційних заходів на внутрішньогосподарській мережі Цирської осушуваль- ної системи призвела до неможливості ефективного використання сільськогосподарських угідь через затоплення понижених ділянок рельєфу. Як заходи щодо раціонального використання та охорони водних і земельних ресур- сів басейну річки Цир пропонуються організація і проведення експлуатаційних заходів, зокрема на внутрігосподарській мережі, а також відновлення водорегулюючої функції дренажної системи шляхом реконструкції та будівництва нової інженерної інфраструк- тури меліоративної системи, що забезпечить двостороннє регулювання дренажного стоку в умовах зміни клімату.

Стаття присвячена дослідженню технологічного процесу очищення газів від пилу електрофільтрами в умовах цементного виробництва з метою розробки автоматизова- ної системи контролю та візуалізації технологічних параметрів, що дає змогу контро- лювати процес у режимі реального часу, вчасно визначити аварійні ситуації. Це питання є актуальним з огляду на те, що цементна промисловість з кожним роком збільшує свою виробничу потужність, а зменшення викидів в атмосферу запилених та отруйних газів дозволить уникнути виплати штрафів та зменшити виплати за шкідливі викиди. Для досягнення поставленої мети було проаналізовано технологічний процес і роботу наяв- ної системи управління обезпиленням газів та визначено, що цю систему можна вдоско- налити шляхом застосування нових підходів і методів управління та візуалізації роботи самої системи у режимі реального часу. Досліджено схему руху часток в електрофільтрі та схему руху газу під дією електричного вітру, на основі цього аналізу виконано мате- матичний опис технологічного процесу та розроблено алгоритми керування струшу- ванням, в якому передбачено корекцію сили струшування, що дає змогу проводити ефек- тивні струшування з мінімальним руйнуванням обладнання електрофільтра. Розроблена система контролю та візуалізації відповідає трирівневій структурі, де на першому рівні виконується вимірювання параметрів технологічного процесу, на другому реалізується логічне управління механізмами згідно алгоритмів керування, а на третьому відбувається взаємодія системи управління з операторами, накопичується та обробляється архівна та оперативна інформація про стан обладнання. Практичне значення полягає в засто- суванні отриманої автоматизованої системи контролю та візуалізації основних техно- логічних параметрів для отримання оперативної інформації у реальному часі як самого технологічного процесу, так і оптимізації режиму струшування електродів при очищенні газів холодного кінця печі від пилу в електрофільтрі.

Динаміка об’єктів з розподіленими параметрами описується диференціальними рівняннями в частинних похідних параболічного типу, які з крайовими умовами є мате- матичними моделями багатьох нестаціонарних нелінійних процесів. Математичними моделями тепломасопереносу є системи рівнянь параболічного типу з такими ж гранич- ними умовами. Усі реальні процеси, як правило, є нелінійними. Вибір оптимального методу розв’я- зання тієї або іншої задачі теорії поля і технічного засобу для її реалізацій є складним питанням. У наш час найбільше поширення при математичному моделюванні складних об’єк- тів з розподіленими параметрами одержали методи дискретизації математичної моделі шляхом просторово-тимчасового квантування. Представлення математичної моделі об’єктів з розподіленими параметрами системами звичайних диференціальних або алгебраїчних рівнянь дозволяє моделювати їх на аналогових і цифрових обчислю- вальних машинах. Можна прийняти, що час роботи циркуляційної системи обмежений часом досягнення температурним фронтом експлуатаційної свердловини. Проведеними дослідженнями [1] встановлено, що теплоприток від гірського масиву, що оточує шар, у реальних пласто- вих умовах не виявляє істотного впливу на час роботи циркуляційної системи в постій- ному температурному режимі. Тому в розрахунках теплопритоком нехтуємо. У добуванні геотермальної енергії має місце напірна фільтрація, при якій величина μ має значення порядку 10-6 м-2. У зв’язку з цим система виходить на стаціонарний режим за час, малий у порівнянні з часом її роботи. У статті пропонується метод моделювання руху температурного фронту з вико- ристанням диференціальної моделі з переходом до кінцево-різницевої. Після обчислення першого наближення значення швидкості руху холодної води це значення уточнюється з використанням ітерацій за різними параметрами моделі.

Petroleum hydrocarbon contamination remains a major challenge confronting soil health, environmental sustainability, and food security in oil exploration areas. In this study, the effect of Bonny Light crude oil on cowpea (Vigna unguiculata L. Walp.) was investigated with a view to assessing its toxicity to plant growth and performance. Pristine soil samples were collected in different pots and contaminated with crude oil to achieve 0.0%, 2.5%, 5.0%, 7.5% and 10.0% v/w contamination levels. Viable seeds of cowpea were planted and monitored for the emergence and subsequent growth for a period of 12 weeks. Results showed that the crude oil extended the period of seed germination and delayed the emergence of sprouts by 2 days at a rate of 96.7%, 80.0%, 50.0%, 96.7%, and 73.3% emergence respectively. The plants’ shoots, roots, and leaves lengths were longer in control than in the contaminated soil. Phytotoxicity study showed that shoots, roots and leaves lengths of the plants were significantly reduced by ≥ 50% of the control. The relative plants' weights, chlorophyll, and the number of leaves were worst affected especially in plants grown in higher crude oil concentrations where fewer or absence of leaves was observed at the end of the experiments. No yield parameter was observed in all plants grown in contaminated soil as opposed to the control where flowers, fruits, and seeds were produced. The findings illustrated that the growth rate of V. unguiculata was severely affected due to hydrocarbon contamination in a concentration-dependent manner. It further demonstrated the imminent danger to food security especially in frontier basins with impending oil exploration activities. Therefore, there is a need to identify and integrate effective measures that minimize or prevent oil spillage in the course of oil exploration activities with a view to avoiding the repeat of persistent pollution problems disturbing host communities.

RNA extraction is an important process before gene expression assessment at the transcriptomic level. RNA is a sensitive material to environmental factors such as temperature and contaminants, so the RNA extraction process generally requires sophisticated and expensive laboratory instruments. In this study, we extract RNA from Staphylococcus aureus bacteria using the PureLink® RNA Mini Kit. The instruments used in this study are basic instruments such as a hand homogenizer and non-thermal centrifuge. The results of RNA extraction were visualized using agarose gel electrophoresis. These results indicate that bacterial RNA extraction can be performed using the PureLink® RNA Mini Kit even with inexpensive basic laboratory instruments.

This study investigates the correlation between leukocyte number and the patient's awareness level after craniotomy surgery, both high (leukocytosis) and low (leukopenia). Several studies reveal that an increase in leukocytes affects mortality rates due to the high level of leukocytes affecting our body's functionalities, including awareness. Previous studies revealed that a leukocyte count exceeding 17.5x106/L was associated with a lower GCS score, a longer hospital stay, and worsening CT scan results, regardless of the type of focal lesion that occurred. This study uses observational methods in the form of retrospective case studies. The data was collected from the medical records of the Operation room at Jemursari Islamic Hospital in 2018-2019 with a sample size of 89. The research was conducted at Jemursari Islamic Hospital Surabaya from May 2018 to August 2019. Data were analyzed using the Spearman correlation test with p <0.05. Results showed no significant relationship between the leukocyte count and the consciousness level of post-craniotomy patients. Future research could estimate the specific effects on the morphology of specific leukocyte cells that are elevated in post-craniotomy patients. This research is expected to provide insight into the effect of leukocytes on consciousness to reduce patient mortality after craniotomy.
