Dendritic cells (DC) generated from human umbilical cord blood might replace patients' DC in attempts to elicit tumor-specific immune response in cancer patients. We studied the efficiency of transfection of human cord blood DC with plasmid DNA carrying the enhanced version of green fluorescent protein (EGFP) as a reporter gene, to test if nonviral gene transfer would be a method to load DC with protein antigens for immunotherapy purposes. Cord blood mononuclear cells were cultured in serum-free medium in the presence of granulocyte-monocyte colony stimulating factor (GM-CSF), stem cell factor (SCF) and Flt-3 ligand (FL), to generate DC from their precursors, and thereafter transfected by electroporation. Maturation of DC was induced by stimulation with GM-CSF, SCF, FL and phorbol myristate acetate (PMA). Transfected DC strongly expressed EGFP, but transfection efficiency of DC, defined as HLA-DR(+) cells lacking lineage-specific markers, did not exceed 2.5%. Expression of the reporter gene was also demonstrated in the DC generated from transfected, purified CD34(+) cord blood cells, by stimulation with GM-CSF, SCF, FL, and tumor necrosis factor alpha (TNF-alpha). Transfection of CD34(+) cells was very efficient, but proliferation of the transfected cells was much reduced as compared to the untransfected cells. Therefore, the yield of transgene-expressing DC was relatively low. In conclusion, nonviral transfection of cord blood DC proved feasible, but considering the requirements for immunotherapy in cancer patients, transfection of differentiated DC or generation of DC from transfected hematopoietic stem cells provide only a limited number of DC expressing the transgene.

Reflections on richness and complementarity in diversity: The Tuning Journal contribution to global education and scholarship
Authors: Gobbi Mary
Published: November 2019

The progress so far with the Journal has more than justified the Spirit evoked by the European Bologna Process and the key role played by the Tuning founders and activists in their endeavor to enable Higher Education Institutions to address the challenges of this Century. They have helped contribute to the necessary reforms of the European Higher Education Space. Tuning commenced with aspirations to facilitate student centred learning underpinned by effective pedagogy, stakeholder engagement and the achievement of quality assured competence-based education. What is crucial in the Tuning vision, particularly as it is now literally sharing experience within the global community, is the commitment to avoid uniformity, celebrate diversity, recognize points of convergence and find opportunities to share good practices. In true academic fashion, we must be ever ready for debate and deliberation.Published online: 29 November 2019
ИССЛЕДОВАНИЕ И АНАЛИЗ МЕТОДОВ ОПРЕДЕЛЕНИЯ ЭФФЕКТИВНОСТИ ПРИМЕНЕНИЯ ТЕХНОЛОГИИ ПРОПАНТНОГО ГИДРОРАЗРЫВА ПЛАСТА
Authors: Галкин Владислав Игнатьевич , Колтырин Артур Николаевич
Published: November 2019

Актуальность. Большинство месторождений ООО «ЛУКОЙЛ-ПЕРМЬ» находятся на завершающей стадии разработки, и на них выполняется большое количество операций гидроразрыва пласта (ГРП). В условиях высокой выработки запасов, обводнения скважин и снижения пластового давления необходимо планировать проведение ГРП на тех скважинах, где может быть получен максимальный прирост дебитов нефти. Цель: разработка методики прогноза дебитов нефти с использованием вероятностно-статистических методов. Объекты: данные по использованию пропантного ГРП на карбонатном В3В4 объекте Батырбайского месторождения. Методы: анализ данных по оценке эффективности ГРП с помощью использования вероятностно-статистических методов. Результаты. С использованием вероятностно-статистического метода построены многомерные математические модели оценки эффективности ГРП, которые позволили определить приросты дебитов нефти. Одним из основных преимуществ вероятностно-статистического метода является то, что все используемые для прогноза показатели, имеющие различные размерности, были переведены в безразмерные величины, что упрощает сопоставительный анализ. Кроме этого, выполнено сравнение полученных приростов дебитов нефти с методом расчета дебита жидкости через удельный коэффициент продуктивности. Выполненный анализ показал, что разработанный вероятностно-статистический метод прогноза обеспечивает более точную сходимость с фактическими данными по приростам дебитов нефти, в отличие от результатов, полученных по методу удельного коэффициента продуктивности. Значения коэффициентов парной корреляции для вероятностно-статистического метода составили по объекту разработки В3В4 – 0,85, тогда как по методу удельной продуктивности, соответственно, – 0,15, что на статистическом уровне подтверждает более высокую эффективность предлагаемого метода.
ВЛИЯНИЕ ПЕТРОФИЗИЧЕСКИХ ПАРАМЕТРОВ РИФОГЕННЫХ КАРБОНАТНЫХ КОЛЛЕКТОРОВ НЕФТЯНЫХ МЕСТОРОЖДЕНИЙ ТУРНЕЙСКО-ФАМЕНСКИХ ОТЛОЖЕНИЙ ВЕРХНЕГО ПРИКАМЬЯ НА ПРОДУКТИВНОСТЬ ДОБЫВАЮЩИХ СКВАЖИН
Authors: Мартюшев Дмитрий Александрович , Зайцев Роман Александрович
Published: November 2019

Актуальность работы обусловлена тем, что большинство карбонатных залежей нефтяных месторождений Верхнего Прикамья, приуроченных к рифовым структурам, относится к коллекторам трещинно-порового типа. При разработке таких сложнопостроенных объектов продуктивность скважин зависит от раскрытости и проницаемости трещин, их относительной емкости и взаимной сообщаемости между трещинами и матрицей, от азимутального распространения естественных трещин по площади залежей. Указанные параметры и факторы по-разному проявляются на отдельных участках залежей в процессе их разработки, и в этой связи вопрос оценки и прогнозирования коэффициентов продуктивности добывающих скважин нефтяных месторождений Верхнего Прикамья является одним из актуальных и приоритетных. Цель: по промысловым данным получить эмпирические зависимости для оперативного прогнозирования параметров естественной трещиноватости и продуктивности добывающих скважин, эксплуатирующие турнейско-фаменские отложения месторождений Верхнего Прикамья. Объекты: турнейско-фаменские карбонатные отложения месторождений Верхнего Прикамья. Методы. В основу работы положены литературные материалы и исследования ученых в данной области. Исследования основаны на фактических промысловых материалах геофизических, гидродинамических исследований, которые проводились на нефтяных месторождениях Верхнего Прикамья; данных лабораторных исследований кернового материала и шлифов горных пород. Результаты. Определены относительная емкостная характеристика трещин, коэффициенты перетока между трещинами и матрицей и средняя раскрытость трещин, а также их динамика при снижении забойных и пластовых давлений в процессе разработки залежей. Получена система эмпирических зависимостей для оценки и прогнозирования средней раскрытости и относительной емкости трещин, коэффициентов перетока между матрицей и трещинами, а также продуктивности добывающих скважин в процессе разработки нефтяных залежей с карбонатными коллекторами.
ПРОФИЛЬ КОНЦЕНТРАЦИИ ВЫСОКОИНЕРЦИОННЫХ ЧАСТИЦ В ПРИСТЕННОЙ ТУРБУЛЕНТНОСТИ ПРИ БОЛЬШИХ ЧИСЛАХ РЕЙНОЛЬДСА
Authors: Сиковский Дмитрий Филиппович
Published: November 2019

Актуальность работы обусловлена многочисленными применениями турбулентных газодисперсных потоков во многих аппаратах и устройствах, применяемых в добыче полезных ископаемых, при транспортировке природных ресурсов, в энергетике, химической технологии и других отраслях промышленности. В качестве примеров можно привести технологии и установки пневмотранспорта порошкообразных материалов, штреки горных выработок, вентиляционные каналы для помещений различных типов, системы газоочистки и т. д. Течения со взвешенными частицами также широко распространены в природе и являются объектами исследований в метеорологии, геоморфологии, гидравлике русловых процессов и речных наносов и др. Взаимодействие инерционных частиц с неоднородными пристенными турбулентными потоками является весьма сложным явлением, требующим детального моделирования на основе глубокого понимания механизмов взаимодействия частиц с многомасштабными турбулентными вихревыми структурами. Цель: моделирование распределения и статистических параметров движения высокоинерционных частиц в пристенной зоне турбулентного потока при больших числах Рейнольдса на основе стохастической лагранжевой модели турбулентности среды. Методы: статистическое моделирование методом Монте-Карло движения частиц на основе стохастической лагранжевой модели турбулентности среды и теории подобия пристенной турбулентности. Результаты. Стохастическое лагранжево моделирование динамики высокоинерционных частиц в логарифмическом слое пристенной турбулентности при больших числах Рейнольдса показало существенную неравновесность статистики скорости частиц вблизи стенки. Показано, что вблизи стенки имеет место вызванная турбофорезом аккумуляция частиц, вследствие которой концентрация частиц на стенке более чем в 3 раза превышает концентрацию частиц в ядре потока при условии упругого отскока частиц от стенки. В то же время интенсивность пульсаций нормальной к стенке компоненты скорости частиц не равна нулю на стенке и составляет примерно 1/3 от интенсивности пульсаций скорости в ядре потока.

Актуальность. Минеральный состав глин тавдинской свиты изучался неоднократно. Полученные результаты, содержащиеся в геологических отчетах и немногочисленных опубликованных работах, зачастую слабо коррелируются друг с другом. Подобное противоречие вызвано отбором проб для технологических испытаний с различных участков, которые относятся к двум подсвитам, имеющим ряд отличий. Возраст, стратиграфическое положение и химико-минералогические особенности пород, слагающих тавдинскую свиту, остаются дискуссионными и актуальными вопросами, что требует дополнительных исследований. Детальное изучение литологии глин тавдинской свиты принимает важное значение в связи с планами по расширению сырьевой базы и потребностью перепрофилизации части производственных мощностей на выпуск новой товарной продукции. Цель работы: изучение вещественного состава глин тавдинской свиты эоцена Западной Сибири для выявления их генезиса и практического использования Методы: полевые исследования, рентгеноструктурный анализ, рентгенофлуоресцентный анализ, определение огнеупорности, масс-спектрометрия с индуктивно-связанной плазмой, сканирующая электронная микроскопия, литолого-петрографический анализ в шлифах. Результаты. Представлены результаты исследований химического и минерального составов, особенностей литологии и микростроения глинистых пород из Кыштырлинского участка (Тюменская область). Глинистые породы обладают определенной вариативностью минерального состава, но неизменным остается глинистый слюдистый смешаннослойно-смектитовый матрикс. В нижней подсвите глинистая масса пород сложена преимущественно иллитом и смешанослойными образованиями иллит-смектитового состава. Глины верхней подсвиты больше соответствуют каолинит-иллит-монтмориллонитовому типу с примесями пирита, минералов кремнезёма, сульфатов, карбонатов и органического вещества. Формирование таких смешаннослойных масс, вероятно, обусловлено трансформацией обломочных минералов и первичного глинистого субстрата. Установленное распределение редкоземельных элементов индицирует существенные изменения в восстановительно-окислительных условиях морского бассейна на различных этапах его существования. Изученные глины рассматриваются как полиминеральные.

The Energetics of the an ExB Propulsor That Avoids the Hidden Momentum Pitfall
Authors: Cornwall Remi
Published: November 2019

This paper updates earlier thoughts by the author on a putative electromagnetic propulsion system, to perform a more detailed energy balance. The previous paper demonstrated how momentum could be dumped to the ground state of the electromagnetic field but a claim was left somewhat hanging at the end of the previous paper, that the work done in changing the craft's velocity would effectively shift the centre of mass of the field-although that would be an infinitesimal shift in practice. The craft must always supply work to change velocity, such as by an accelerate/de-accelerate cycle and superficially this looks to violate the conservation of energy; we prove that this isn't so.

Mastering reading comprehension is a must for language learners. Without mastering reading comprehension students aren’t able to grasp the message on their written form of learning material. Yet, reading comprehension oftenly considered to be difficult by students. This may caused by teacher’s method of teaching that doesn’t effective. This article compare between the use of Cooperative Learning method model Teams-Games-Tournaments (TGT) and Direct Instructional Method (DI) to teach studentsz reading comprehension. Here describe there is significant difference in reading comprehension achievement between the students taught using TGT and those taught using DI of the eighth grade students of one state junior high school in Grogol, and whether TGT is more effective than DI to teach reading comprehension. The method used in this study is experimental method (comparative study). The population of the research is all the eighth grade students. The sample was taken by using cluster random sampling. Two groups of student were taken, VIII-B as experimental group and VIII-C as control group. The instrument to collect data is test. The data were analyzed using t-test formula. The computation showed that t-observation (to) is 3.32 consulting t-table (78, 0.05) = 1.96, therefore the to is higher than tt. It is concluded that there’s significant difference between experimental and control group. Besides, the mean of the group of students taught using TGT is 62.62, while that of those taught using DI is 59.46, meaning that TGT gives better achievement than DI. Thus, TGT is more effective than DI to teach reading comprehension.

Published: November 2019

This article describes a study on the process of developing and using English teaching materials by English teachers in a vocational school. The study was initiated by observing the classroom activities which focused on how teachers used the teaching materials. Beside the observation process, the data also gathered through an interview between the researcher and the two teachers. The result of data analysis showed that the process of developing teaching materials consisted of two major steps; 1) student’s need analysis process and 2) materials adaptation process. Meanwhile, the developed materials such as pictures, videos, course books, and direct listening materials were applied in the arranged discussion activity. It can be sum up that the teachers developed teaching materials by considering student’s needs. The teaching materials were developed by adapting several existed teaching materials. They were then used mostly in the discussion activity and used as a brainstorming for students.
Overview of Russo-Kurdish Relations in the Context of Turkey and Syria (1813-2019)
Authors: KONAK İsmet
Published: November 2019

When Russia builds military,
economic, and social relationships with Turkey and Syria, it also actively
considers how to win the “kindness” of the Kurds. The Putin administration,
aware of this necessity, has attempted to pursue a “balanced policy” in recent
years. Despite the policy’s issues during the Afrin (Kurdish: Efrîn) Campaign
and the Operation of Peace Spring, Russo-Kurdish relations are constantly
developing and growing in importance. The relationship, which began following
the Treaty of Gulistan, has always followed the bumby cruise. The Ottoman
Empire (and later the Republic of Turkey) has played an especially active role
in determining the scope of this relationship. This paper uses a general
framework to analyze the Russo-Kurdish relationship from the age of Imperial
Russia to the modern era of the Russian Federation.
Racismo na educação escolar
Authors: Santos Gabriel Gustavo , Aparecida Lopes do Vale Rosiney
Published: November 2019

Este artigo tem por objetivo problematizar e refletir acerca do sujeito negro e a sua relação com o saber escolar. Para tanto, escolhemos, como ponto de partida, o texto literário Lembrança das lições (1996), do autor negro Cuti, Luiz Silva, para servir como elemento deflagrador dessa problemática, já que esse texto literário materializa para a ficção os dramas comumente vivenciados pela população negra nas escolas. Partindo de uma pesquisa bibliográfica, pretendemos discutir sobre o modo como o negro é representado nas mídias e ambientes escolares e o impacto dessas representações na forma como ele enxerga a sua condição e, consequentemente, no modo como se relaciona com o saber escolar. No decorrer de nossa investigação pudemos constatar que muitos discursos, com ampla difusão em diversas mídias e no próprio âmbito escolar, podem propiciar a perpetuação do racismo de cor, de modo que suas consequências na vida de um sujeito negro podem, e geralmente são, como exposto no texto supracitado, ser devastadoras.
The effect of Endovascular Aneurysm Repair on Renal Function in Patients Treated for Abdominal Aortic Aneurysm

Published: November 2019

Aim:

The effect of endovascular aneurysm repair in patients treated for abdominal aortic aneurysm has
not been clearly defined. The objective of the present article was to provide a contemporary literature review and
perform an analysis to determine the effect of EVAR on renal function in the early post-operative period and
during follow-up.

Methods:

A systematic review of the literature was undertaken to identify all studies reporting the effect of
EVAR on renal function. Outcome data were pooled and combined overall effect sizes were calculated using
fixed or random-effects models.

Results:

Thirty-two studies reporting on 24846 patients were included. Acute renal failure after EVAR occurred
with an estimated frequency of 9% (95%CI: 5-16%; I2=97%). Median follow-up period was 19.5 months (range
1-60 months). The estimated frequency of chronic renal failure during follow-up was 7% (95%CI: 3-17%;
I2=98%). Hemodialysis was required in 2% (1-3%; I2=97%) of the cases.

Conclusion:

High-level evidence demonstrating the effect of EVAR on the incidence of acute and chronic renal
failure is lacking. Based on the current available data, nearly 10% of patients undergoing EVAR for AAA have an
increased risk for renal dysfunction after the procedure. Whether this deterioration may lead to a worse outcome
has not been adequately proved.
Acute Kidney Injury after Complex Endovascular Aneurysm Repair
Authors: Liang Nathan L. , Mohapatra Abhisekh , Avgerinos Efthymios D. , Katsargyris Athanasios
Published: November 2019

Background:

Complex endovascular repair of abdominal aortic aneurysm carries higher perioperative
morbidity than standard infrarenal endovascular repair.

Objective:

This study reviews the incidence and associated factors of acute kidney injury in complex aortic endovascular
repair of juxtarenal, pararenal, and thoracoabdominal aortic aneurysms.

Methods:

A literature review was performed for all studies on the endovascular repair of juxtarenal, pararenal,
and thoracoabdominal aneurysms that evaluated rates of acute kidney injury as an outcome. Outcomes were further
analyzed by the level of anatomic complexity and method of repair.

Results:

52 studies met inclusion criteria, with a total of 5454 individuals undergoing repair from 2004 to 2017.
The overall rate of acute kidney injury ranged widely from 0 to 41%, with a rate of hemodialysis from 0 to 19%
(temporary) and 0 to 14% (permanent). Increasing anatomic complexity was associated with higher rates of acute
kidney injury. Mode of endovascular repair, learning curve effect, and preoperative chronic renal insufficiency
did not demonstrate any associations with the outcome.

Conclusion:

Published rates of acute kidney injury in complex aortic aneurysm repair vary widely with few definitively
associated factors other than increasing anatomic complexity and operative time. Further study is
needed for the identification of predictors related to postoperative acute kidney injury.
Impact of Heavy Metals on Host Cells: Special Focus on Nickel-Mediated Pathologies and Novel Interventional Approaches
Authors: Magrone Thea , Russo Matteo A. , Jirillo Emilio
Published: November 2019

Background:

Heavy metals [arsenic, aluminium, cadmium, chromium, cobalt, lead, nickel
(Ni), palladium and titanium] are environmental contaminants able to impact with host human cells,
thus, leading to severe damage.

Objective:

In this review, the detrimental effects of several heavy metals on human organs will be discussed
and special emphasis will be placed on Ni. In particular, Ni is able to interact with Toll-like
receptor-4 on immune and non-immune cells, thus, triggering the cascade of pro-inflammatory cytokines.
Then, inflammatory and allergic reactions mediated by Ni will be illustrated within different organs,
even including the central nervous system, airways and the gastrointestinal system.

Discussion:

Different therapeutic strategies have been adopted to mitigate Ni-induced inflammatoryallergic
reactions. In this context, the ability of polyphenols to counteract the inflammatory pathway
induced by Ni on peripheral blood leukocytes from Ni-sensitized patients will be outlined. In particular,
polyphenols are able to decrease serum levels of interleukin (IL)-17, while increasing levels of IL-
10. These data suggest that the equilibrium between T regulatory cells and T helper 17 cells is recovered
with IL-10 acting as an anti-inflammatory cytokine. In the same context, polyphenols reduced
elevated serum levels of nitric oxide, thus, expressing their anti-oxidant potential. Finally, the carcinogenic
potential of heavy metals, even including Ni, will be highlighted.

Conclusion:

Heavy metals, particularly Ni, are spread in the environment. Nutritional approaches
seem to represent a novel option in the treatment of Ni-induced damage and, among them, polyphenols
should be taken into consideration for their anti-oxidant and anti-inflammatory activities.

:

Aging has been considered a progressive decrease of a living organism’s homeodynamics,
which indicates a reduction of psycho-biological resilience. This narrative review provides an
overview of the available literature related to the holistic approach of integrative medicine, Psychoneuroendocrineimmunology
(PNEI) and hormesis in the aging process. On the basis of Pathophysiology
of cell senescence and of chronic degenerative diseases, possible preventive/therapeutic
pathways have been examined. Chronic low grade cellular inflammation and chronic stress have
been shown as the general interlinked factors inducing aging, on the basis of complex biochemical,
cell and multi-organ derangements. The main cell degenerative processes which have been related
to aging are: altered mitochondria DNA/metabolism, excessive oxidative stress, glycation, alteration
of autophagy and proteasome, and genome alterations. Literature about longevity-targeting interventions,
beyond conventional medicine, describes a spectrum of possible measures to improve
psycho-biological resilience, based on the PNEI paradigm, on hormesis and upon mitochondriatargeted
interventions. Calorie restriction, exercising, fasting, nutraceuticals, sleep regulation, specific
breathing, meditation and psychotherapy are discussed, among others.

Authors: Jain Jay Kumar , Chauhan Dipti , Sharma Sanjay
Published: November 2019

Background & Objective:

The main aim of this paper is to development of efficient model of minimize the energy for wireless sensor networks. In this paper we have proposed the dual probability based energy estimation model in wireless sensor network.

Methods:

We proposed dual probability based function measure the expected value of energy for the transmission of data. This function creates subgroup of networks based on energy function and will change the operation of energy management in scenario of sensor node data processing. This function also integrates the cloud based services with sensor network. The benefit of this function is that it increases the throughput of network and quality of service.

Results:

The proposed model is simulated in MATLAB R-2014a environment and the results are obtained using different scenario of network density. Finally, we analyze the performance of our proposed work with respect to following metrics: Data Utility, Energy Consumptions, and Data Reconstruction Error.

Conclusion:

The dual probability based function reduces the level value of sensors node grouping of data according to their design model. So the overall performance of proposed model is better instead of CP model.
