Treatment of injuries to peripheral nerves after a segmental defect is one of the most challenging surgicalproblems. Therapies for peripheral nerves injury are largely ineffective. Therefore, the current study wasconducted to investigate effects either acellular human umbilical cord tissue powder on repair 1 cm criticalsize defect radial nerve guided by bovine urinary bladder matrix conduit alone or seeded with mesenchymalstem cells derived from human umbilical cord. For this purpose, sixteen healthy mongrel dogs were used.They were randomly divided into two equal groups (n=8), before proceeding with the surgical procedures,the dogs were generally anesthetized and aseptic conditions were established. Then, the surgery was carriedout with the aid of magnifying lens. All dogs subjected to radial nerve neurotmesis from the right limb. Inthe scaffold group, a 1cm of radial nerve was transected and resulted gap bridged with a portion of 14mmacellular bovine urinary bladder submucosa conduit which was then filled with 0.05mg acellular humanumbilical cord powder and then sutured to the two stumps using 6-0 nylon epineural by simple interruptedpattern. In combination group, the gap was bridged with acellular bovine urinary bladder submucosa conduitwhich was filled with 0.05mg acellular human umbilical cord powder then seeded with 50 µl (5x106)mesenchymal stem cells derived from human umbilical cord, then fixed onto two stumps using 6-0 nylonepineural by simple interrupted pattern. Each group was further divided into two equal subgroups (n=4)categorized according to the post operation periods, that were 8 and 16th weeks for neurohistopathologicalexaminations. The histopathological examination of regenerated nerve sections (two samples of 5 mm lengtheach) were collected from the middle (coaptation site) and distal segments were used to determine the degreeof the radial nerve regeneration. The histopathological findings relative convergence between the scaffoldand combination groups in their components such as the increased number of Schwann cells proliferation,parallel arrangement of nerve fibers and remarkable angiogenesis on 16th weeks. In conclusion; this studyshowed that the decellularized both scaffolds alone or seeded with mesenchymal stem cells derived fromhuman umbilical cord could support the radial nerve regeneration and allow the reinnervation of the targetorgan.

Published: March 2021

Obesity and bronchial asthma (BA) are two major health concerns. These entities have been furtherestablished by several meta-analyses. Still, these analyses denote to ‘‘general-obesity’’, that classicallymeasured via body mass index (BMI), which is a broad measure unable to distinguish between lean musclebulk and body fats. Thus, other indices, should applied like waist perimeter, waist/hip ratio, and conicityindex (CI), which are also reasonable, and normalized easily. Sufficient studies on the BA association withCI are lacking up till now. Our work was designed based on the theory that obesity worsens BA symptoms,aiming to evaluate the asthma relationships and CI.Methodology: This is an observational-study conducted on 410 asthmatics consulting outpatient-respiratoryclinic. They were diagnosed by pulmonologists, then referred for spirometric pulmonary functions (SPF)and fractional exhaled nitric oxide (FENO) tests. Patients’ weight, height and BMI were measured andaccordingly divided into two-classes ‘‘nonobese and obese’’. The X2-test was applied to analyze theassociations among qualitative parameters. Level of significant acceptance was 5%, and the analyses hadcompleted by using the SPSS package.Results: Mean±SD of weight, height, and BMI were 80.9±15.4, 1.64±1.6, and 30.8±5.4, respectively. AObindices were 96.2±14.3, 107.1±10.6, 0.98±0.9 and1.25±0.1 for waist, hip, W/HR, and CI respectively. Themean FENO-measures were 43.8 ppb. There was a significant variation in the means of PEF and FEV1/FVConly, although the FENO-tests were equivalent between the sexes.There was a strong association betweenCI with increasing age. The CI had a weak non-significant association with increasing FENO-results.Conclusion: The conicity index as an anthropometric index of central obesity is not associated with theFENO test among adult asthmatic patients. There was non-significant variation between obese and nonobesegroups. The CI is not useful in the prediction of adult BA.

Published: March 2021

This study attempts to identify the manifestations of extreme shyness among students, shed light on the effect of counselling interventions in reducing the level of non-positive shyness, and highlight behavioural indicators that may lead to improved social interaction. The study researchers utilised a systematic approach to study a female gifted student with a high level of shyness that prevents her from engaging in normal social interaction. The study participant is a gifted student designated gifted as indicated by the Mawhiba scale in 2019-2020, and she was deliberately chosen for the purpose of this four-week case study. Multiple resources and a special tool for data collection were used to analyse the output and ultimately suggest a package of consultancy solutions for this study. The study reveals that the thorough and extensive consultancy program makes a remarkable impact on the characteristics of the study participant and to the same degree on the family and school. In addition, a number of specific strategies were identified as successful means in attaining reduced self-consciousness while increasing confidence and social interaction skills. From a quantitative perspective, the study utilises Sternberg’s emotional intelligence index and a shyness scale, which led the researchers to better understand the study participant's emotional intelligence and lower her level of shyness and inhibition.
Age differences in sustained attention tasks: A meta-analysis
Authors: Vallesi Antonino , Tronelli Virginia , Lomi Francesco , Pezzetta Rachele
Published: March 2021

Many aspects of attention decline with aging. There is a current debate on how aging also affects sustained attention. In this study, we contribute to this debate by meta-analytically comparing performance on the go/no-go Sustained Attention to Response Task (SART) in younger and older adults. We included only studies in which the SART had a low proportion of no-go trials (5%–30%), there was a random or quasirandom stimulus presentation, and data on both healthy younger and older adults were available. A total of 12 studies were suitable with 832 younger adults and 690 older adults. Results showed that older adults were slower than younger adults on go trials (g= 1, 95% CI [.72, 1.27]) and more accurate than younger adults on no-go trials (g= .59, 95% CI [.32, .85]). Moreover, older adults were slower after a no-go error than younger adults (g= .79, 95% CI [.60, .99]). These results are compatible with an age-related processing speed deficit, mostly suggested by longer go RTs, but also with an increased preference for a prudent strategy, as demonstrated by fewer no-go errors and greater posterror slowing in older adults. An inhibitory deficit account could not explain these findings, as older adults actually outperformed younger adults by producing fewer false alarms to no-go stimuli. These findings point to a more prudent strategy when using attentional resources in aging that allows reducing the false-alarm rate in tasks producing a tendency for automatic responding.

Authors: Arriola Guillermo
Published: March 2021

La producción actual de mezclas asfálticas en caliente para carreteras, aportan grandes cantidades de gases tóxicos nocivos para el medio ambiente debido a las altas temperaturas durante su preparación, por lo que se necesitan tomar medidas correctivas que sean sostenibles y económicas. Éstas medidas pueden verse reflejadas durante la elaboración de mezclas con la inclusión de otros materiales como aceites, polímeros o plásticos que influyan en la disminución de la temperatura. En la investigación se optó por incorporar un aceite crudo de palma de una planta de origen africano muy usado en la ciudad de Yurimaguas, Perú. Los aceites que se emplearon fueron del tipo industrial y artesanal a una temperatura de mezcla máxima de 130°C. Las variaciones de temperatura aceptables estuvieron en el rango de 128°C, 125,50°C, 120°C, 117,50°C y 115°C, considerando en todos los casos los requerimientos de laboratorio. Los resultados obtenidos indican que el aceite crudo de palma si influye en el diseño de mezclas asfálticas de hasta 115°C bajando considerablemente en 45°C respecto a una mezcla asfáltica en caliente típica, sin perder de lado la óptima relación estabilidad y flujo.

The most topical issues of upstream development in the Republic of Kazakhstan from the point of view of geology, drilling and development are considered. In view of the complexity of the development of hydrocarbon resources in the future, it is important to facilitate access to geological data and to involve the geological community as much as possible in their analysis and generalization. Rational use of data provides for remastering of regional seismic lines, and updating the structure model, primarily the Caspian Basin, based on modern processing and reinterpretation. The value of timely data analysis is illustrated in three specific examples. The experience of drilling wells dictates its requirements for contracts, equipment, personnel training, which brings forward a number of urgent issues presented in the work. One of the key roles in the development is played by the objectivity of recording parameters and accounting for products. The correct placement of wells, the effectiveness of which is shown by example and the reasonable implementation of the latest achievements, is a real step towards high yield of subsoil in today's difficult economic conditions

Согласно мировым прогнозам, в связи с истощением запасов легких нефтей в недалекой перспективе возникнет проблема переработки исключительно тяжелого углеводородного сырья. Для решения этого вопроса необходимо совершенствовать или частично изменять существующие технологии нефтепереработки, например, путем интегрирования классических и нетрадиционных методов. В случае использования механо-волнового воздействия на обрабатываемое нефтяное сырье, имеет место деструкция его молекулярных структур, протекание химических реакций, облегчающих процесс более глубокой переработки. Целью статьи является исследование процессов превращений высокомолекулярных компонентов тяжелого нефтяного сырьяпри термомеханическом – гидродинамическом воздействии на него.

В процессе гидродинамического воздействия на нефтяное сырье происходит разрыв длинноцепочных молекул углеводородных соединений, т. е. изменяется их исходный химический состав. На основании исследования физико-химических свойств нефтяного сырья - исходной тяжелой нефти и нефтяных остатков, характера их фракционного состава при атмосферной разгонке, предложен механо-волновой-гидродинамический метод переработки без использования реагентов и катализаторов. Разрабатываемая технология может обеспечить эффективное решение задач по углублению переработки тяжелой нефти: увеличению выхода дистиллятов, снижение количества нефтяных кубовых остатков, при энергетически малозатратной и экологической безопасности технологии производства.

Президент Касым-Жомарт Токаев в Послании народу «Казахстан в новой реальности: время действий» указал, что «длительный нефтяной суперцикл завершился и надо быть готовым к новой конъюнктуре мирового рынка. Создание по-настоящему диверсифицированной, технологичной экономики для нас не просто необходимость, этот путь уже безальтернативен. При этом экономика обязана работать на повышение благосостояния народа». Более того, шестое направление плана действий в Послании Главы государства посвящено экологии и защите биоразнообразия. Но экология должна входить в пятерку главных приоритетов государства. К тому же в плане действий не отражена энергетическая утилизация твердых бытовых отходов и политика низкоуглеродного развития. Страны ЕС своей главной целью объявили достижение нулевых выбросов парниковых газов к 2050 г. и уже в следующем году планируют ввести «пограничный углеродный налог» на импортируемую продукцию из стран с высоким уровнем выбросов, куда, к сожалению, относится, также Казахстан, который входит в первую десятку стран с самым высоким уровнем углеродоемкости ВВП. Хотя вклад страны в общемировые выбросы парниковых газов не превышает 1% [1].

Falling oil prices raise questions about the future of the energy industry globally, regionally and locally, as well as the role of fossil fuels in the transition to a more sustainable energy future after the pandemic. The global economy is already undergoing an energy transition from fossil fuels to more sustainable energy sources. Renewable energy is increasingly deflationary, and oil prices will have to compete with it, despite falling oil prices driven by the economy and pandemic. It is not known what life will look like in the post-«COVID-19» oil industry, even if oil demand returns to normal, supply consumption will take some time. We may see further diversification in the energy market and for renewable energy to play a greater role. However, it is important that energy resources are balanced in a sustainable and equitable way that supports the growth of the V.P. TUDORACHE1*, Associate Professor PhD.

Hydraulic fracturing is one of the most effective methods for stimulation. At present, it is actively used around the world, as well as in our country, in Kazakhstan. Currently, many producing fields are at their advanced production stage, and new fields are in such geological conditions when hydrocarbons are extracted from tight reservoirs. Hydraulic fracturing allows maintaining the economic profitability of the development of such fields. However, like other stimulation methods, hydraulic fracturing has a number of disadvantages, including proppant flowback. Proppant flowback after hydraulic fracturing treatments is quite serious challenge. This could be the deterioration of the downhole equipment with a subsequent frequent workovers; decrease in well productivity. Some special methods including preventive as well as corrective measures already exist in the industry to overcome the proppant flowback problems. The paper considers systematization of fourteen preventive methods. Based on physical, chemical, and technological properties of each listed method, as well as the knowledge of the main reasons of the proppant flowback the authors systematize all methods and propose an initial decision-making algorithm and a matrix of methods applicability. The algorithm and the matrix were tested under conditions of Uzen field, Kazakhstan. The paper may be of interest to fracturing engineers, production engineers, operation engineers, and other professionals

Выполнено обобщение доступных геолого-геофизических материалов и опубликованных данных о кольцевых субвертикальных структурах и флюидопроявлениях в пределах фрагмента Скифско-Туранской плиты (Каспийский регион). На акватории Северного и Среднего Каспия ранее были выявлены: зоны пленочных «сликов» не техногенного происхождения; зоны естественных нефтепроявлений; зоны газовых сипов; «газовые трубы», «газо-водо-грязевые трубы», покмарки и экс-покмарки; бугристые формы донного рельефа, приуроченные к очагам газопроявлений. На полуостровах Бузачи и Тюбкараган ранее были выявлены типичные газо-водо-грязевые сопки, именуемые «сальзы». На территориях Арало-Каспийского региона часто встречаются конусообразные формы рельефа – «чукалаки». Эти объекты традиционно изучались геоморфологами, ботаниками и почвоведами, которые формирование их объясняли разгрузкой подземных вод. Анализ бузачинских грязевых сопок и чукалаков позволяет предполагать их генетическую идентичность. Высказаны соображения об актуальности их изучения с целью экологического мониторинга и возможного использования при геологоразведочных работах на углеводородное сырье (Часть II).

В статье рассматриваются результаты исследования процесса каталитического риформинга прямогонного бензина, полученного из смеси нефти месторождений, расположенных в Южном регионе Казахстана. Изучен индивидуальный и групповой углеводородный состав исходного гидроочищенного бензина и риформата с целью установления степени превращения углеводородов на разных этапах каталитического риформинга. В результате исследования процесса каталитического риформинга прямогонного бензиновой фракции (85–180°С) установлен химизм и механизм реакций, которые основываются на следующих реакциях: дегидроциклизация парафиновых углеводородов, дегидрирование и дегидроизомеризация нафтеновых, изомеризация нафтеновых и парафиновых углеводородов. Сравнение физико-химических свойств и группового углеводородного состава гидрогенизата и продуктов риформинга показывает, что сумма н-парафиновых и нафтеновых углеводородов после каталитического риформинга уменьшается в 3–4 раза по сравнению с исходным бензином, а концентрация ароматических углеводородов значительно возрастает за счет реакции дегидрирования цикланов и дегидроциклизации нормальных парафинов.
