Authors: Thuy Nguyen Thi Thu , Dung Nghiem Trung , Sekiguchi Kazuhiko , Yamaguchi Ryosuke , Thuy Pham Chau , Bang Ho Quoc
Published: June 2017

Atmospheric ultrafine particles (NPs or PM0.1) were investigated at a roadside of Nguyen Van Cu road (Vinacomin) and at a mixed site in the Hanoi University of Science and Technology (HUST) in Hanoi, Vietnam. The sampling was conducted during a rainy reason and a dry season to determine the characteristics of atmospheric elemental and organic carbon in the nanoparticles. The relative contributions of organic carbon (OC) and elemental carbon (EC) to total carbon (TC) at HUST were 83.7 – 85.0% and 15.0–16.3 %, respectively; whereas those at Vinacomin’s sampling site accounted for 78.6 – 81.5% and 18.5 – 21.4 %, respectively. The study provides an interesting observation that particulate OC and EC have spatial and temporal variations dependent on sampling sites and weather conditions. In contrast, consistent OC/EC ratios were also found at both seasons of each location, in which the ratios were from 3.68 to 5.68. The correlations of OC and EC were found in the rainy season with the slopes ranging from 0.21–0.34; however, these correlations were not observed in the dry season. The relationships between OC and EC, char – EC and soot – EC can be used in primarily determining the sources of NPs in the atmosphere.

Published: June 2017

In this paper, the analytical solution for the cross-ply laminated composite double curved shell panels with stiffeners is presented. Based on the smeared stiffeners technique and the first shear deformation theory (FSDT), the motion equations are derived by applying the Hamilton’s principle. The Navier’s solution for the simply supported boundary condition for all edges is presented. The numerical results are veriﬁed with the known results in the literature. The effects of the number of stiffeners, dimensions of stiffeners, and lamination scheme of cross-ply laminated composite doubly curved shell panels on the natural fundamental frequencies are investigated.
Twelve tips for implementing artistic learning approaches in anatomy education
Authors: Keenan Iain D. , Hutchinson Joseph , Bell Kathryn
Published: June 2017

This article was migrated. The article was marked as recommended. To enhance learning and maximise student satisfaction while simultaneously optimising costs and resources within the modern context and environment of integrated anatomy education, it is vital that innovative methods of delivering learning and teaching are considered for implementation into medical curricula. The development of learning processes including observation, visualisation, haptic reasoning and visuospatial ability are strongly associated with the use of artistic approaches. In addition to being crucial for medical student learning of anatomy and other life sciences, such skills are also relevant for training in surgery, clinical observation and diagnosis. The twelve tips outlined here have been identified with the intention of providing guidance for anatomy educators aiming to incorporate innovative creative and artistic approaches into their own teaching practice within medical curricula. These proposals are underpinned by educational theory and recent research that has investigated artistic learning methods in medical education. Recommendations are also based on our personal experiences from both the undergraduate student point of view as well as the academic educator perspective with respect to the usage of creative and artistic learning approaches in anatomy education at Newcastle University.
(N, N, N’, N’-Tetramethy -p- phebylebediamine dihydrochloride) as a New Analytical Reagent for Spectrophotometric Determination of Iron (III). (Fadhil M. Najib and Nawzad N. Ahmad)
Authors: Najib Fadhil , Ahmad Nawzad
Published: June 2017

New reagent N, N,-N,-N - Tetramethyl-pe phenylenediamine dihydrochloride (TMPDA-2HCl) was described for the determination of Iron (II) spectrophotometrically. Beer's Law was obeyed between (0.4- 2.4 ppm) Iron (III). Optimum conditions were : pH(2-3), λmax= 560 nm, 2ml (0.001M) reagent freshly prepared for final 25ml solution containing 10 to 60 μg [i .e. 0.4-2.4 ppm Fe(III)], color develops after 10 minutes and remains stable for three hours.

Best Straight line drawn by the method of least square gave correlation coefficient of (0.999) between (0 - 2 ppm). At lower limit of Fe(III) determination (0.4 ppm), maximum error did not exceed 5% in the presence of accumulative interfering ions with coefficient of variation of 1.8% there values, for 2 ppm Fe(III), were less that 4% and 0.34% respectively. Average extinction coefficient was about (1.5 x 10^4 L.mol-1. cm-1). The Stoichiometry of the complex [ Fe(III) - R ] was 1:1.

Interferences of 27 ions were studied for their tolerance levels. Only few ions interfered seriously which were Cu2+, Ag+, Zn2+, Sn2+, C2O42-, and F-.

Published: June 2017

Background: The exact role of lycopene has not been studied in the past for its hepatoprotective effects. Hence it was decided to explore its anti-oxidant and anti-inflammatory properties in acute and chronic models of drug- induced hepatotoxicity with the aim to evaluate hepatoprotective potential in rat models of paracetamol and antitubercular drugs (isoniazid + rifampicin) induced hepatotoxicity.Methods: The study was carried out in 70 Wistar rats in two phases. In phase I, models of paracetamol and anti-tubercular drugs induced hepatotoxicity were standardized in 22 Wistar rats and in phase II, hepatoprotective potential of lycopene was evaluated in paracetamol and anti-tubercular drugs induced hepatic damage using 48 Wistar rats. The effects of lycopene were compared with silymarin.Results: There was a significant (p <0.05) reduction in serum bilirubin levels with silymarin and lycopene 10mg/kg treated groups signifying protection against hepatic damage, while vehicle control and lycopene 5mg/kg treated groups had high bilirubin values. Similarly, significant (p <0.001) reduction in the levels of serum transaminases were observed with all the treatment groups though more evident in the positive control and lycopene 10mg/kg treated groups.Conclusions: The results of the present study prove that lycopene exerts hepatoprotective effect against paracetamol and anti-tubercular drugs induced hepatic damage in rats. Lycopene needs to be evaluated in other models of hepatotoxicity and further studies are required to delineate its mechanism of action. Lycopene could be a potential hepatoprotective for clinical use in future.

Authors: Дудкина Марина Петровна
Published: June 2017

В статье проанализированы основные проблемы, связанные с необходимостью воспроизводства человеческого капитала в условиях превращения Западной Сибири в один из основных промышленных регионов страны. Показано влияние Великой Отечественной войны на данный процесс. На основе архивных материалов раскрывается зависимость заболеваемости рабочих предприятий городов Западной Сибири от условий труда в основных промышленных отраслях региона: угольной, металлургической и химической. Эта проблема рассматривалась властью с социально-медицинской точки зрения, поскольку от состояния охраны здоровья в конечном итоге зависело выполнение плановых заданий. Начиная с конца 1940-х гг. государство рассматривало совершенствование производственных и бытовых условий на промышленных предприятиях в качестве приоритетной задачи социально-экономической политики. Уменьшение отрицательных последствий профессиональной заболеваемости на экономическое развитие страны в целом и региона в частности стало одной из главных целей крупной структурной реформы здравоохранения конца 1940-х-начала 1950-х гг. Проведен анализ воздействия основных патогенных факторов в конкретных отраслях промышленности. Приведены конкретные примеры такого воздействия, зафиксированные областными и республиканскими органами управления здравоохранением. Выявлено, что в рассматриваемый период в целом произошло снижение профессиональной заболеваемости, хотя полностью ее преодолеть, конечно, не удалось.

Authors: Camacho Tauta Javier Fernando , Reyes Ortiz Oscar Javier , Méndez González Dolly Fernanda
Published: June 2017

El propósito de este trabajo es analizar experimentalmente una metodología alternativa para el proceso de compactación de suelos en laboratorio. Tradicionalmente se ha utilizado el método conocido como “compactación proctor”, aunque siempre se ha reconocido que no representa fielmente las condiciones en que se produce la compactación en el campo. En el ensayo de compactación giratoria, el proceso se produce por amasado, lo cual asemeja mejor el efecto de los equipos de vibrocompactación en obra. Se realizaron diferentes ensayos con presiones verticales entre 100 y 400 kPa, se mantuvo constante el ángulo de giro (1.25º) y el material se ensayó con diferentes contenidos de humedad. Con los resultados de los ensayos se determinó que para obtener una curva de compactación similar a la conseguida en el ensayo de proctor modificado se pueden utilizar dos opciones, la primera es trabajar con una presión vertical de 400 kPa, 100 giros y ángulo de 1.25º y la segunda opción es aplicar una presión 350 kPa, 300 giros y un ángulo de 1.25º.

Authors: Gaffar Shabarni , Aji Sofyan Multazam N , Hartati Yeni W , Ishmayana Safri , Subroto Toto
Published: June 2017

Basic natriuretic peptide (BNP) is a polypeptide hormone consist of 32 amino acids that secreted by the heart ventricle to respond the excessive stretching of heart muscle cells. BNP can be used as prognostic marker for patients with heart failure. The presence of BNP in blood can be detected by BNP antibody, which is anti BNP-single chain variable fragment (Anti BNP-SCFV). The antibody is a combination of polypeptides between varying region on the heavy chain (VH) and the light chain (VL) of immunoglobulin. Anti BNP-SCFV will bind to BNP through the antigen-antibody interaction. Concentration of BNP in a patientâs blood can be detected through the interaction of BNP with Anti BNP-SCFV using immunosensor method. Production of recombinant Anti BNP-SCFV in Escherichia coli as host is reported in the present study. Anti BNP-SCFV was expressed in fusion form with OmpC signal peptide that direct the protein to a periplasmic space. Expression was performed under RhaBad promoter as control using L-rhamnose as inducer. SDS-PAGE characterization showed consistent band at 28 kDa, which was assumed as Anti BNP-SCFV. The optimum expression was found at four hours after induction with 4 mM inducer. Anti BNP-SCFV was secreted from the cell as characterized by the presence of the protein on periplasmic membrane and extracellular fraction.

Published: June 2017

[abstFig src='/00290003/02.jpg' width='300' text='Underactuated rimless wheel model for collisionless walking' ] In this paper, control methods for achieving collisionless walking of robotic underactuated walkers are discussed. Collisionless walking is a gait type of motion that does not cause collision during the landing of the swing-leg end. First, we introduce a simple point-footed walker and develop its motion equation. Second, we propose two time-scale output deadbeat control approaches and demonstrate mathematically their ability to generate a stable, collisionless walking gait. Overcoming potential barriers at midstance as well as the stability of zero dynamics are guaranteed accordingly. Furthermore, we investigate fundamental gait properties through numerical simulations.

Published: June 2017

[abstFig src='/00290003/05.jpg' width='300' text='Concept of visual lifting approach' ] Biped locomotion generated by control methods based on Zero-Moment Point (ZMP) has been achieved and its efficacy for stable walking, where ZMP-based walking does not include the falling state, has been verified extensively. The walking control that does not depend on ZMP – we call it dynamical walking – can be used in walking that utilizes kicks by toes, which looks natural but is vulnerable to turnover. Therefore, keeping the walking of dynamical motion stable is indispensable to the realization of human-like natural walking – the authors perceive the human walking, which includes toe off states, as natural walking. Our research group has developed a walking model, which includes slipping, impact, surface-contacting and line-contacting of foot. This model was derived from the Newton-Euler (NE) method. The “Visual Lifting Approach” (VLA) strategy inspired from human walking motion utilizing visual perception, was used in order to enhance robust walking and prevent the robot from falling, without utilizing ZMP. The VLA consists of walking gate generation visual lifting feedback and feedforward. In this study, simulation results confirmed that bipedal walking dynamics, which include a slipping state between foot and floor, converge to a stable walking limit cycle.

[abstFig src='/00290003/06.jpg' width='300' text='Short- and long-period sliding passive compass gaits' ] This paper investigates the modeling and analysis of the sliding passive dynamic walking of a compass-like biped robot with pointed feet. First, we present the passive compass-like biped model and redevelop the inelastic collision equation for stance-leg exchange, taking the impulsive frictional effect into account. Second, we numerically show that two different steady motions, the short- and long-period sliding passive compass gaits, can be generated according to the initial conditions in the presence of the effects of the hip damper and impulsive frictional force. Furthermore, we numerically analyze the change characteristics of the gait descriptors with respect to the system parameters, and we discuss the relationship between the short- and long-period gaits.

Published: June 2017

[abstFig src='/00290003/07.jpg' width='300' text='4DOF serial-parallel hybrid manipulator' ] For adapting to the complex working environments of amphibious manipulators, we proposed a serial-parallel hybrid quadruped walking manipulator. We simplified the leg mechanism of the serial-parallel hybrid manipulator as a 2UPU-UPR parallel mechanism, and then analyzed the degree of freedom (DOF) of the parallel mechanism by using the screw theory. The results show that the position of theYdirection and the pose of theZdirection are two independent variables which influence the mechanism movement. We deduced the kinematics inverse solution and the velocity Jacobian matrix of the 2UPU-UPR parallel mechanism. Based on the analysis of the Jacobian matrix, three kinds of kinematic singularities of the 2UPU-UPR parallel mechanism are identified. The results show that the 2UPU-UPR parallel mechanism doesn’t have the kinematic inverse singularity, but it has three kinds of kinematic forward singularities and two kinds of combined singularities. Finally, the variation of motorial parameters of this 2UPU-UPR parallel mechanism was discussed by a calculation example.
KONTRIBUSI METODE MAṢLAḤAH MURSALAH IMAM MALIK TERHADAP PENGEMBANGAN HUKUM EKONOMI SYARI’AH KONTEMPORER
Authors: Asiyah Nur , Ghofur Abdul
Published: June 2017

This paper discusses the contribution of maṣlaḥah mursalah Imam Maliki to the development of sharia economic law. Maṣlaḥah mursalah is one of the methods of determining Islamic law initiated by Imam Malik. Based on the author's search, there are at least two conclusions about the contribution of the maṣlaḥah mursalah Imam Malik method to the development of Shariah economic law. First, maṣlaḥah mursalah as one of the approach model in ijtihād becomes very vital in the development of sharia economic law and siyāsah iqtiṣādiyyah (economic policy). Because the new problems in the emerging economics in this global world continue to grow, which textually found no proposition in the Qur'an and al-Sunnah. Secondly, the need for fatwas, especially in the fatwa of DSN-MUI, which is based on maṣlaḥah mursalah (kemaslahatan) becomes very urgent. The demands of the times have required the Muslim jurists to see the complexity of the contemporary problem and choose a more convenient (taysir) and avoiding difficulties (al-ḥaraj); And the emergence of new cases requires the existence of ijtihād by considering this maṣlaḥah mursalah aspect.

Tulisan ini membahas tentang kontribusi maṣlaḥah mursalah Imam Maliki bagi pengembangan hukum ekonomi syari’ah. Maṣlaḥah mursalah merupakan salah satu metode penetapan hukum Islam yang digagas oleh Imam Malik. Berdasarkan penelusuran penulis, setidaknya ada dua kesimpulan mengenai konstribusi metode maṣlaḥah mursalah Imam Malik terhadap pengembangan hukum ekonomi Syari’ah. Pertama, maṣlaḥah mursalah sebagai salah satu model pendekatan dalam ijtihād menjadi sangat vital dalam pengembangan hukum ekonomi syari’ah dan siyāsah iqtiṣādiyiyah (kebijakan ekonomi). Sebab persoalan baru di bidang ekonomi yang muncul dalam dunia global ini terus berkembang, yang secara tekstual tidak ditemukan dalilnya di dalam al-Qur’an dan al-Sunnah. Kedua, kebutuhan fatwa, terutama dalam fatwa DSN-MUI, yang didasarkan atas maṣlaḥah mursalah (kemaslahatan ) ini menjadi sangat urgen. Tuntutan perkembangan zaman mengharuskan para ahli hukum Islam melihat kompleksitas masalah kontemporer dan memilih pandangan yang lebih memudahkan (taysir) dan menghindari kesulitan (al-ḥaraj); dan munculnya kasus-kasus baru mengharuskan adanya ijtihād memper­timbangkan aspek maṣlaḥah mursalah ini.
Application of a water balance adapted to intermittent water supply and flat-rate tariffs without customer metering in Tiruvannamalai, India
Authors: Mastaller Miran , Klingel Philipp
Published: June 2017

Establishing the water balance developed by the International Water Association (IWA) is a worldwide applied approach to determine and analyse water losses in water distribution systems (WDS). The water balance covers those parts of a WDS within the responsibility of the water utility. Water losses occurring ‘before’ a customer meter are at the expense of the utility, while water lost or wasted ‘after’ the meter is paid for by the customer. This applies to systems where customer metering is in place and/or consumption is charged according to the consumed volumes. However, many WDS in the world lack customer meters, are operated intermittently and apply flat-rate tariffs. In intermittent supplies, a considerable amount of water is lost or wasted within the private properties. The flat-rate tariff might not cover this amount or part of the amount. Thus, actual consumption and wastage should be separately quantified with respect to the utility's water reduction measures. Accepting the described conditions, the authors have developed an adaption of the IWA water balance and the methods to establish the balance. In this paper the application of the developed approach in an initially unmetered WDS with intermittent water supply in the city of Tiruvannamalai, India, is presented.

Biogenic manganese oxides (BioMnOx) can be applied for the effective removal and recovery of trace metals from wastewater because of their high adsorption capacity. Although a freshwater continuous-flow system for a nitrifier-based Mn-oxidizing microbial community for producing BioMnOx has been developed so far, a seawater continuous-flow bioreactor system for BioMnOx production has not been established. Here, we report BioMnOx production by a methanotroph-based microbial community by using a continuous-flow bioreactor system. The bioreactor system was operated using a deep-sea sediment sample as the inoculum with methane as the energy source for over 2 years. The BioMnOx production became evident after 370 days of reactor operation. The maximum Mn oxidation rate was 11.4 mg L−1 day−1. An X-ray diffraction analysis showed that the accumulated BioMnOx was birnessite. 16S rRNA gene-based clone analyses indicated that methanotrophic bacterial members were relatively abundant in the system; however, none of the known Mn-oxidizing bacteria were detected. A continuous-flow bioreactor system coupled with nitrification was also run in parallel for 636 days, but no BioMnOx production was observed in this bioreactor system. The comparative experiments indicated that the methanotroph-based microbial community, rather than the nitrifier-based community, was effective for BioMnOx production under the marine environmental conditions.

Peritonitis is a very common complication in patients treated with continuous ambulatory peritoneal dialysis. The most common causes are gram positive cocci (part of the normal skin flora), and then gram negative bacteria, while fungi are listed as a rare cause of peritonitis. Aeromonas species are identified as a rare cause of continuous ambulatory peritoneal dialysis-related peritonitis. Among them, Aeromonas hydrophila is somewhat more common, followed by Aeromonas caviae.Case presentation. We reported a case of continuous ambulatory peritoneal dialysis peritonitis caused by Aeromonas sobria that is extremely rare cause of this type of peritonitis. In our patient, pseudomembranous colitis occured as a complication and, reinfection – another episode of peritonitis with Klebsiella pneumoniae. Treatment with third-episode cephalosporins was successful and patient continued treatment with continuous ambulatory peritoneal dialysis. Conclusions. The rare causes of peritonitis should not be ignored, especially those which lead to increased morbidity and mortality of patients.

Published: June 2017

Экспериментально изучено влияние оптической подсветки на прохождение терагерцeвого излучения через объемный кристалл полуизолирующего GaAs. Установлено, что без подсветки поглощение электромагнитных волн с частотой порядка 1 THz в исследуемом кристалле практически отсутствует. Оптическая подсветка в области фундаментального поглощения кристалла не влияет на пропускание терагерцевых волн. В то же время при подсветке немного ниже края фундаментального поглощения, т. е. фактически в область прозрачности, пропускание терагерцевого излучения резко падает. При температуре жидкого гелия максимальный эффект достигается при энергии оптических фотонов примерно на 30 meV меньшей ширины запрещенной зоны кристалла. Дальнейшая отстройка подсветки в область меньших энергий сопровождается практически полным восстановлением пропускания. С увеличением температуры образца спектральная область эффективного действия подсветки смещается вместе со сдвигом края фундаментального поглощения в сторону меньших энергий фотонов.

Особенности дифракции света в упорядоченном монослое сфер
Authors: Романов С.Г.
Published: June 2017

Исследованы структура и оптические дифракционные свойства монослоев монодисперсных сфер, кристаллизованных на прозрачных диэлектрических подложках. Рассмотрены два типа дифракционных явлений: поверхностная дифракция света на решетке сфер и волноводные резонансы в плоскости монослоя. Для экспериментального исследования этих явлений измерены оптические спектры ретроотражения и пропускания в зависимости от угла падения света и азимутальной ориентации плоскости падения. Найдено количественное совпадение между структурой монослоя, определенной методами сканирующей электронной микроскопии и дифракции света. Сделан вывод о применимости одномерной дифракции Фраунгофера для описания поверхностной дифракции в гексагональной решетке сфер. В случае наклонного падения света найдена анизотропия спектров дифракции и пропускания в зависимости от ориентации плоскости падения света относительно решетки сфер и линейной поляризации падающего света. Волноводные резонансы плоского двумерного фотонного кристалла аппроксимированы в рамках модели дифракции света в "пустой" гексагональной решетке. Наилучшая аппроксимация дисперсии волноводного резонанса достигнута при использовании зависящего от длины волны эффективного показателя преломления. Продемонстрировано подавление поверхностной дифракции волноводными резонансами фотонного кристалла. Порядки поверхностной дифракции идентифицированы как дифракция в особых точках зон Бриллюэна плоского двумерного фотонного кристалла.

У першу добу значно (на 76,5 %) зменшилася кількість дітей із показником «++++» та на 87 % — з «+++». Із третьої доби кетонурія не визначалася. Висновки. Застосування препарату Гепаргін® в комплексній терапії АС у дітей показало його ефективність у швидкій регресії і купіруванні клінічних симптомів. Використання даного препарату для корекції метаболічних порушень при кетоацидозі патогенетично обґрунтовано. Гепаргін® добре переноситься, зручний у застосуванні у дітей з раннього віку. Результати проведеного спостереження дозволяють рекомендувати Гепаргін® як доповнен-ня до базисної терапії при лікуванні ацетонемічних станів у дитячому віці.
Взаємозв’язок між функціональним нирковим резервом, рівнем сечової кислоти та якістю життя пацієнтів із хронічною хворобою нирок І–ІІІ стадії
Authors: Savytska L.M.
Published: June 2017

Актуальність. Визначення функціонального ниркового резерву дає клініцисту додаткову інформацію про перебіг захворювання, дозволяє раніше виявити порушення, відповідно, провести їх корекцію і вплинути на подальший перебіг захворювання та його прогноз. Мета дослідження: оцінити стан функціонального ниркового резерву в пацієнтів із хронічною хворобою нирок І–ІІІ стадії та виявити його взаємозв’язок із рівнем сечової кислоти в сироватці крові та якістю життя пацієнтів. Матеріали та методи. У 22 пацієнтів із хронічною хворобою нирок було проведено обстеження для визначення стану функціонального ниркового резерву за методикою А.І. Гоженка, адаптованою до амбулаторних умов, із виявленням рівнів сечової кислоти в сироватці крові до та після водно-сольового навантаження 0,5% розчином натрію хлориду з розрахунку 0,5 % від маси тіла. Якість життя визначалася за опитувальником SF-36. Результати. Функціональний нирковий резерв був збережений у 19 пацієнтів (87 %) і становив у середньому 115 ± 54 %, знижений — у 2 пацієнтів (9 %) і становив у середньому 5,7 ± 2,1 %, відсутній — в 1 пацієнта (4 %) і становив –41 %. Рівень функціонального ниркового резерву корелював із рівнем сечової кислоти в сироватці крові, визначеним через годину після проведення водно-сольового навантаження (p = 0,60, p-level 0,018), а також із середнім значенням сечової кислоти, визначеним за 4 роки (p = 0,74, p-level 0,0015). Виявлено також взаємозв’язок між станом функціонального ниркового резерву і такими показниками якості життя, як фізичне функціонування (p = 0,60, p-level 0,03), життєва активність (p = 0,68, p-level 0,01), психічне здоров’я (p = 0,58, p-level 0,04). Висновки. При отриманні високих значень функціонального ниркового резерву в пацієнта варто простежити в динаміці за показниками його сечової кислоти.

Актуальність. Гепатит С залишається однією з провідних проблем внутрішньолікарняних інфекцій, пов’язаних із гемотрансфузіями, введенням препаратів крові, медичними інвазивними маніпуляціями з діагностичною та лікувальною метою. Мета дослідження: установити популяційний рівень таксонів мікробіоти порожнини товстої кишки хворих на хронічний гепатит С. Матеріали та методи. Мікробіологічному дослідженню підлягали 72 зразки вмісту порожнини товстої кишки хворих на хронічний гепатит С, із них жінок було 44, чоловіків — 28, вік хворих становив від 21 до 53 років (у середньому — 37,5 ± 1,7 року). Результати. На основі проведених досліджень установлено, що популяційний рівень бактерій роду Bifidobacterium у порожнині товстої кишки хворих на хронічний гепатит С знижується на 41,28 %, Lactobacillus spp. — на 41,15 %, коефіцієнт кількісного домінування зменшується у 2,07 і 2,22 раза, коефіцієнт значущості — у 3,25 та 3,36 раза відповідно, що сприяє підвищенню популяційного рівня, коефіцієнта кількісного домінування і значущості Bacteroides spp. на 65,01 та 24,94 % відповідно, підвищується на 52,21 % кількість бактерій Escherichia spp., на 26,48 % — Enterococcus spp., на 57,43 % — Peptostreptococcus spp., у 2,03 раза — бактерій роду Clostridium. Результати проведеного дослідження дають можливість практичному лікарю ефективно проводити етіотропну терапію та корекцію змін біотопу пробіотичними засобами з урахуванням кількісних змін даного мікробіоценозу. Висновки. У порожнині товстої кишки хворих на хронічний гепатит С формується виражений дефіцит автохтонних облігатних Bifidobacterium spp. на 41,28 %, Lactobacillus spp. — на 42,15 %, зростає концентрація в біотопі Bacteroides spp. на 65,01 %, Peptostreptococcus spp. — на 57,43 %, Clostridium spp. — у 2,03 раза, а також бактерій роду Escherichia — на 52,21 %, Enterococcus spp. — на 26,48 %.

Psychological contract breach, organizational disidentification, and employees' unethical behavior: Organizational ethical climate as moderator
Authors: Ning NI , Zhaoyi Li
Published: June 2017

We explored the effect of psychological contract breach on employees' unethical behavior and examined the mediating and moderating roles of organizational disidentification and organizational ethical climate, respectively, using data from 362 paired questionnaires. The results of multiple
linear regression analysis showed that psychological contract breach was positively related to employees' unethical behavior and also that organizational disidentification completely mediated the relationship between psychological contract breach and employees' unethical behavior. In addition,
organizational ethical climate moderated the relationship between psychological contract breach and employees' unethical behavior by weakening the mediating role of organizational disidentification. The results demonstrated that avoidance of organizational disidentification and cultivation
of a higher level of organizational ethical climate were conducive to the reduction of employees' unethical behavior.
Diagrammatic Praxis
Authors: Sher Doruff
Published: June 2017

Diagrammatic Praxis was a post-doctoral research process drawing upon applied concepts of the diagram previously explored in my dissertation, ‘The Translocal Event and the Polyrhythmic Diagram.’ As a researcher in the Art, Research, Theory and Innovation (ARTI) lectoraat of the Amsterdam School for the Arts, the primary focus was on image/text relationality as a vehicle for investigating applied theoretical practice in artistic processes. I worked with Foucault’s concept of the diagram, rejuvenated by Deleuze as abstract machine and Massumi’s concept of the biogram. Thinking the diagram entails negotiating several registers of relations between forces immanent to a field of experience. A diagrammatic practice emphasizes movement with and through the dynamic intensities of an inter-disciplinary field, instantiating the commingled performativity of theory and artmaking through fielding. It experientially engages energetic transductions between unformed matter and unformalised function, between the discursive and the non-discursive, the visible and articulable, content and expression, chaos and order, catastrophe and rhythm. The research aims to contribute to emerging discourse on artistic research as experimental methods of reading and writing are interwoven with artmaking processes.
Additionally, the current wave of discourse on vibrant materiality, object ontologies and thing theory resonate with collaborative, diagrammatic methods. Diagrammatic praxis is situated within interdisciplinary investigations of the collaborative dynamics of mattering. How, as Bruno Latour has pointed out, matters of fact emanate as matters of concern. How objects, things, performers and publics might generate the felt concerns of the event. This proposition of gathering, through an intricate mesh of mattering inclusive of things at all scales of experience, from quarks to cosmos, from facts to fictions excites what matters as the experience of the relational dynamics of the event and its emerging concerns.
The material presented in JAR is a compilation of a fraction of the image and text elements from a three-year process, shaped as a graphic essay. Works include graphic translations, works on paper and published texts created from an integral diagrammatic method.
Taking the Book Apart
Authors: Sarah Alford
Published: June 2017

The exposition opens up the artist’s investigations into the historical figure Ellen Gates Starr, co-founder of the Hull House, a settlement house in Chicago, Midwest United States. Reflecting on the life and work of Gates Starr and on the artist’s own works inspired by these, a particular focus of the exposition is the link between artistic mark making and political practice. By way of close reading and research, the artist excavates Starr’s artistic practice and writing, to explore how artistic mark making informed by Starr’s praxis might come to shed some light on our contemporary situation. The exposition also reconsiders some of the politics at stake for the Arts and Craft movement.
Oorwonde - a tactile experience
Authors: Laura Maes
Published: June 2017

The exposition focuses on Oorwonde, a specific practical experiment within the research project Sounding sound art. The work, which falls somewhere between a sound installation and an interactive performance, consists of specially constructed stainless steel operating table upon which visitors, or ‘patients’ are invited to undergo ‘aural surgery’. Next to the concept and construction of Oorwonde, related practices are discussed in terms of their use of subsonic sound in interactive works or installations. The exposition introduces contextual information in regard to the artist’s broader work on the question of what constitutes ‘sound art’, while it’s main purpose remains the description and analysis of this new sound work, as a piece of artistic research.

Authors: Bertha Bermudez (Collaborator)  , Barbara Meneses Gutierrez  , Sarah Fdili Alaoui  , Frederic Bevilacqua  , Chris Ziegler  , Marijke Hoogenboom  , Scott deLahunta
Published: June 2017

The Interactive Installation Double Skin/Double Mind is a virtual interactive version of the Double Skin/Double Mind workshop. This workshop, which has been taught by dance company Emio Greco | PC since 1996, represents the basis of the creative work of choreographers Emio Greco and Pieter C. Scholten.

Participants in this workshop are challenged to discover new interpretations of their dancing body through the movement tracking program Gesture Follower developed by Frédéric Bevilacqua (IRCAM). As result of this comparison different feedback, including emotive icons, sonification and text displays is given through an interface lay out developed by Chris Ziegler. Participants are accompanied by different visualization and sonic information while mentally and physically travelling through the Double Skin/Double Mind structure.
Professional as well as non-professional dancers are invited to experience this installation.
Moore-Penrose equations in involutive residuated semigroups and involutive quantales
Authors: Ignjatovic Jelena , Ciric Miroslav
Published: June 2017

In this paper we provide procedures for testing the existence of various
types of generalized inverses in involutive residuated semigroups and
involutive quantales defined by the Moore-Penrose equations, and for
computing the extreme inverses whenever they exist. We also determine
certain instances when a? = a*, whenever a? exists. The obtained results can
be applied to a wide class of quantales of fuzzy relations and fuzzy
matrices, as well as to Gelfand quantales.
On the second hankel determinant for the kth-root transform of analytic functions
Authors: Alarifi Najla , Ali Rosihan , Ravichandran V.
Published: June 2017

Let f be a normalized analytic function in the open unit disk of the complex
plane satisfying zf'(z)/f(z) is subordinate to a given analytic function
?. A sharp bound is obtained for the second Hankel determinant of the
kth-root transform z[f(zk)/zk]1/k. Best bounds for the Hankel
determinant are also derived for the kth-root transform of several other
classes, which include the class of ?-convex functions and ?-logarithmically
convex functions. These bounds are expressed in terms of the coefficients of
the given function ?, and thus connect with earlier known results for
particular choices of ?.

covariant tensor fields of order two.
Dutch banking culture six years after the fall of ABN AMRO bank
Authors: van Staveren
Published: June 2017

This article presents the results of a survey among more than six hundred
bankers in the Netherlands about banking culture. It addresses the question
why trust in banks remains so low (45% of clients trust banks in the
Netherlands). The key findings indicate that the problem is not so much
immoral bankers or a few rotten apples but rather the dominance of a
competitive banking culture. The findings suggest that clients? trust may be
regained when banks leave behind their focus on performance targets,
financial incentives, and behavioral regulation and move instead to a caring
culture with a focus on relationships and open discussion of ethical
dilemma?s.
