Authors: Nguyen Ngoc-Van Thi , Nguyen Kim-Ngan Huynh , Huynh Ngọc , Pham To-Lien , Kim Kyeong Ho
Published: June 2022

Pesticide residues in vegetables (watercress, mustard green, choy sum, daikon, okra, and yam) from Mekong Delta, Vietnam were analysed by liquid chromatography-tandem mass spectroscopy (LC-MS/MS). QuEChERS (Quick, Easy, Cheap, Effective, Rugged, Safe) extraction, matrix-matched calibration, and dynamic multiple reaction monitoring methods were used. The linear range used was 5 - 200 ng/mL, resulting in R2 > 0.99. The recovery was satisfactory with values within 74.47 - 116.93%, and the RSD was < 15% for most compounds. The percentage of samples with residues above the maximum residue levels (MRLs) was 59%. Pesticide residues were detected above their MRLs in samples of watercress (47%), mustard green (80%), choy sum (83%), daikon (87%), and yam (60%). The results indicated the prevalence of pesticide residues in commonly consumed vegetables in Vietnam, and emphasised the urgent need to develop comprehensive intervention measures to reduce the potential health risk to consumers.

Published: June 2022

The most essential process of Acanthus ilicifolius L. tea production is drying. The current convective drying method (e.g., hot-air drying) of producing dried A. ilicifolius is inadequate due to its high energy consumption and long drying time, thus leading to undesirable final product quality. The objective of the present work was therefore to evaluate how the different standard drying methods and conditions namely hot-air drying (HAD), microwave drying (MWD), microwave-vacuum drying (MWVD), and freeze drying (FD) affect the greenness, chlorophyll content, antioxidant content, antioxidant activity, and anti-tyrosinase activity of A. ilicifolius leaves. MWD increased the drying rate of A. ilicifolius leaves by 6.7 times as compared to HAD. The logarithmic model best described moisture evolution during MWD and MWVD. The coefficient of diffusivity for MWD and MWVD was 10 times higher than that of HAD. The greenness of samples dried using HAD, MWD, and MWVD was 58.6 - 78.9, 51.7 - 73.9, and 56.4 - 68.8% lower than that of FD, respectively. As compared to HAD at 80°C, the greenness of the sample dried using MWD and MWVD at 700 W was 16.63 and 5.18% higher, respectively. MWD at 700 W was the best condition for minimising decomposition of the flavonoids (26.0%) and antioxidant activity namely DPPH assay (27.9%), FRAP scavenging (37.1%), reducing power (29.8%), Fe2+ chelating ability (22.9%), and Fe2+-1,10-Phenanthroline reducing (33.6%) of these medicinal leaves as compared to FD. Chlorophyll content, total phenolics, ABTS assay, and tyrosinase enzyme inhibition of leaves dried at MWD 700 W were not significantly different from those of the FD sample.

Authors: Thummajitsakul Sirikul , Boonburapong Bongkoj , Silprasit Kun
Published: June 2022

Fourier-transform infrared spectroscopy (FTIR) chemometrics and determination of antioxidant and anti-glucosidase activities of flower extract and natural dye solution from Sesbania javanica were performed. Total phenolic content and total flavonoid content were the highest in ethanolic flower extract, while antioxidant activity (1/EC50 = 0.4935) and α-glucosidase inhibition (1/EC50 = 2.9671) were the highest in dye solution, obtained from mixing white clay filler with aqueous dye extract. The correlations of FTIR data, bioactive compound contents, and biological activities were assessed by partial least squares structural equation modelling. Results showed that a strongly positive relationship was significantly demonstrated between FTIR fingerprints and bioactive compound contents (β = 0.825, t = 17.037, p value < 0.05), and between bioactive compound contents and biological activities (β = 0.563, t = 3.000, p value < 0.05). However, a strongly negative relationship was significantly found between FTIR fingerprints and biological activities (β = -1.204, t = 6.065, p value < 0.05). Moreover, the PCA and cluster analysis from FTIR data led to well grouping in PC plots and phylogenetic trees. Interestingly, the PCA and cluster analysis from FTIR data of plant extracts in powdered form provided better separation in PC plots and phylogenetic trees than in liquid form.

Investigation of the Relationship between Online Privacy Concerns and Internet Addiction among University Students
Authors: YAZGAN Çağdaş Ümit
Published: June 2022

The fact that the cyber environment does not have clear boundaries, and the difficulties in taking control of this environment, can turn online sharing into a source of concern in terms of privacy. In particular, the tendency of internet addicts to use the internet uncontrollably can increase the probability of experiencing privacy concerns. This research aims to reveal the relationship between internet addiction levels and online privacy concerns of university youth, one of the segments most addressed by web-based communication technologies. The research was designed with a cross-sectional and correlational survey design within the scope of quantitative research methods. The sample of the research consists of 524 students studying at a state university in Turkey. Quantitative data were collected face-to-face through an introductory information form, and a questionnaire including the scales of “Online Privacy Concern” and “Internet Addiction”. The study determined that online privacy concerns were significantly higher among first-year students, female students, and those using Instagram accounts. It was determined that male students had higher internet addiction levels. In the study, it was revealed that as the internet addiction levels of university students increased, their online privacy concerns also increased. In addition, it was determined that internet addiction explained 15.7% of the total variance of online privacy concerns. Based on the positive relationship between internet addiction and online privacy concern levels of university students, it can be said that the problems related to internet use intersect, intertwine and feed each other.

Türkiye’de pek çok çocuk kanalı ve bu kanallarda yayınlanan birçok çizgi film bulunmaktadır. Yerli ve yabancı kaynaklı olan bu çizgi filmler, değer aktarımı konusunda büyük bir rol üstlenmektedir. Fakat çizgi filmlerin olumlu değerleri olduğu kadar olumsuz değerleri de içerdiği yadsınamaz bir gerçektir. Çocuklar, çizgi filmlerdeki karakterleri model alarak değerleri kazanmaktadırlar. Dolayısıyla da çizgi filmlerin olumlu ve olumsuz değerleri içerip içermediklerinin tespiti önem arz etmektedir. Bu nedenle de bu araştırmada ülkemizde yayınlanan ve yerli bir yapım olan Niloya çizgi filmi, içerdiği değerler açısından incelenmiştir. Doküman incelemesi yöntemi kullanılarak yapılan araştırma sonucunda Niloya’nın internette yayınlanan 79 bölümünden seçkisiz olarak belirlenen 20 bölümünde 20 farklı değer kategorisinde toplam 128 değer tespit edilmiş ve bu değerler içerisinde en sık tekrar eden değerlerin yardımseverlik, nezaket, sevgi, saygı değerleri olduğu belirlenmiştir. Öte yandan Niloya çizgi filminin incelenen hiçbir bölümünde travmatik olabilecek korku veya şiddet içeren herhangi bir söz, fiil ya da görüntüye yer verilmediği tespit edilmiş ve bu bulgulardan yola çıkarak Niloya çizgi filminin çocuklara değer aktarımı konusunda katkı sağlayacağı sonucuna ulaşılmıştır.
Microscale Discrete Element Model for Simulating Bridging Behavior of Fractured Glass Laminates
Authors: Wang Xing-er , Yang Jian , Peng Shennan , Wang Yige , Hou Xiaonan
Published: June 2022

The bridging behavior between fragments is one vital factor in the post-fracture stage of glass laminates. A particle-based discrete element model was developed in this work to simulate the bridging behavior of fractured glass laminates. The model was based on the calibration of hyperelastic PVB material properties using soft-bond model and further validated with the experimental data as well as the observations from through-crack-tensile tests. In order to investigate the bridging performance of fractured glass laminates with multiple fragments under uniaxial tension, three factors encompassing the crack aligning, fragment number and adhesion conditions were considered to perform a parametric study. The results give an exploratory application of the developed discrete element models in the estimation of the post-fracture behaviors. It is found that the smaller fragment size can diminish the tension-stiffening effect in the non-aligned case which might generate an enhancing ratio of initial modulus up to nearly 3.6. The non-aligned cracks can also lead to a very high strength if the adhesion ability can be guaranteed. However, the delamination of fragments is expected to control the post-fracture strength of fractured glass laminates with PVB interlayer.

Evaluación de la propuesta de aprendizaje bimodal como alternativa en el post-confinamiento
Authors: Peña Fernández Mª Ángeles M , Peña-Fernández Antonio
Published: June 2022

El modelo de educación bimodal adoptado por algunas universidades españolas durante el post-confinamiento se ha fundamentado en la compatibilización de la enseñanza presencial y la no presencial, para acomodarse de forma satisfactoria a la nueva realidad de las aulas universitarias. El salto a la virtualidad del curso pasado nos permitió enriquecer el modelo de enseñanza tradicional con respecto al futuro, y el recorrido del curso actual nos lleva a la combinación de ambos tipos de educación, presencial y virtual, cuya principal contribución es la de dar continuidad a un curso lectivo, y también, la de lograr la flexibilización de las estrategias pedagógicas. Además, el replanteamiento del proceso de enseñanza-aprendizaje ha supuesto una importante reestructuración de espacios y procesos que aseguran no sólo la salud de todos los miembros de la comunidad universitaria, sino una docencia de calidad orientada a promover el desarrollo personal e intelectual permanente de los estudiantes en el tiempo. El éxito de la transformación social en la que estamos inmersos depende en gran medida de la educación, por ello, la comunidad educativa debe ajustase adecuadamente a esas nuevas circunstancias. En el futuro será importante indagar con perspectiva sobre la repercusión de todos los cambios provocados por la COVID en el proceso de enseñanza y aprendizaje de estudiantes y profesores.  Un aspecto transcendental será conocer el progreso de los estudiantes en la era postpandemia y adoptar las acciones pedagógicas que sean necesarias para adaptarnos a dicho nuevo escenario.
Fertility preservation for patients with cancer
Authors: Lee Sanghoon , Kim Tak
Published: June 2022

Background: The survival rate of cancer patients is increasing owing to the early diagnosis and treatment methods. Radiotherapy and chemotherapy may cause serious complications, such as ovarian failure and infertility. In particular, preservation of fertility in women of reproductive age with cancer could improve their quality of life as well as reduce social and psychological pain.Current Concepts: Embryo or oocyte cryopreservation is a method of fertility preservation; however, it cannot be utilized by all women with cancer because of the complications of the condition and treatment method. Ovarian tissue cryopreservation and transplantation enables fertility preservation in those needing immediate cancer treatment, such as chemotherapy or radiotherapy, or those unqualified for ovarian stimulation. A recent review reported that frozen-thawed ovarian transplantation led to approximately 130 live births with a conception rate of approximately 30%. Endocrine function recovery occurred in 92.9% of the patients between 3.5 and 6.5 months after transplantation.Discussion and Conclusion: In this study, we introduced various methods and strategies for improving the outcomes of ovarian tissue cryopreservation and transplantation. These results could serve as a reference for patients and clinicians to choose the best options for fertility preservation based on the patient’s current situation and condition.

Published: June 2022

Background: The rapid increase in the number of coronavirus disease (COVID-19) patients led to the operation of COVID-19 facilities for patients with mild COVID-19 in South Korea. We analyzed the correlation and effect of risk factors associated with the worsening of patients with mild COVID-19 leading to their transfer from a community treatment center to a hospital.Methods: This retrospective cohort observational study included 1,208 COVID-19 patients with mild symptoms who were admitted to the Namsan Community Treatment Center between June 2020 and January 2021. A chi-square test was performed to examine the differences in the transfer rate by age, sex, nationality, presence of symptoms at admission, and season, and a multivariable logistic regression analysis was performed to examine the association of variables to the hospitalization rate.Results: Of the 1,208 patients, 212 (17.5%) were transferred to a hospital due to clinical deterioration. Increasing odds of hospital transfer were associated significantly with higher age and presentation in autumn, whereas sex and symptomatic illness at admission did not show a statistically significant association.Conclusion: The findings indicate the importance of the initial risk classification of COVID-19 patients based on thorough assessment and close monitoring, timely allocation of appropriate resources to high-risk groups that are likely to develop severe disease, and reduction of medical resource wastage and limiting of administrative force to ensure that patients receive the best treatment.
Signaling Sustainability: Exploring Consumer Perspectives on
Communicating Apparel Sustainability Information
Authors: Williams Annie , Hodges Nancy
Published: June 2022

The fashion industry is characterized by unsustainable production and
consumption. However, a consistently noted barrier to sustainable and
responsible apparel consumption is a lack of consumer knowledge. A
potential solution to mitigate this barrier is to use apparel labeling to signal
the sustainability of an item to consumers. Thus, the purpose of this study is
to employ signaling theory to explore the aspects of sustainability that resonate
with consumers and why, the modes of communication preferred by
consumers, and how such information would affect their apparel consumption
decisions. In-depth interviews were conducted with a diverse sample
of twenty participants. Analysis of the data resulted in the identification of
three emergent themes related to communicating information about sustainability
that were used to structure the interpretation: Its Importance is
Relative, Signal Mode vs. Message, and Increasing the Interest Level. Overall,
participants preferred simple, yet detailed messages on apparel labels
to communicate aspects of an apparel item’s sustainability. Ultimately, such
labeling signals sustainability to consumers, enabling them to differentiate
between sustainable and unsustainable apparel.
FPIC, international law, social space, and indigenous territories in FPIC during extractive projects in Latin America. A romantic or tragic story?
Authors:   COCEMFE  (Madrid-España), Macias Marín Aguasantas , Lapierre Robles Michelle André ,   COMFOR-SUDOE; Universidad de Valladolid (Valladolid-España)
Published: June 2022

The development and implementation of the free, prior, and informed consent (FPIC) can be understood both as a “romantic” and “tragic” story, using a sharp reflection made by Susan Marks (2012) regarding Human Rights. Following this idea, this essay intends to analyse the main developments of FPIC international human rights in the last three decades (the successful story) and the clear and strong limitations of its use in Latin America (the tragic side to it).Despite the fact that the romantic narrative tells us about a progressive recognition and protection of indigenous rights in international law, especially with instruments such as the ILO Convention 169 (ILO-C169) and the United Nations Declaration of the Rights of Indigenous Peoples (UNDRIP), these advances have been and are currently deactivated. Through the revision of postcolonial literature and an analysis of relevant research in Latin America, this essay explains how the supposed progress is clearly limited by imbalances in the history of international law itself and in the territorial governance system that is configured in large-scale extractive projects, where FPIC is applied or not. In this manner, despite apparently overcoming colonial times against indigenous peoples, the permanent structure of neo-colonization of indigenous territory prevails for an ever-growing global market.
Acoso sexual callejero verbal y no verbal: fenómeno social naturalizado.
Authors:   Universidad de Otavalo (Otavalo-Ecuador), Saavedra Román Tatiana
Published: June 2022

El artículo presenta los hallazgos relevantes con respecto a la naturalización del acoso sexual callejero, producto de la investigación de grado titulada Mecanismos de sensibilización sobre la naturalización e invisibilización del acoso sexual callejero verbal y no verbal en estudiantes universitarios de Otavalo. Se empleó una metodología cualitativa, para poder comprender las experiencias, actitudes y opiniones sobre la temática de estudio. El acoso sexual callejero es un problema social que repercute en la integridad del ser humano. Atañe toda manifestación física, verbal y no verbal no consentida, llevando consigo una connotación sexual reproducida en el espacio público. Dichas expresiones se encaminan a las microviolencias cotidianas, donde la sociedad las vincula como actos normalizados. Se constató que, por sus acciones "naturalizadas" se ha favorecido su "invisibilización" como problema, desconociéndose a su vez la magnitud por la permisividad de estas prácticas dentro de la ciudadanía.

Authors:   Universidad de Venecia ( Venecia-Italia), Manea Anna ,   FLACSO- Ecuador (Quito-Ecuador)
Published: June 2022

A partir del concepto de informalidad laboral se analizan nuevas formas de trabajo generadas por la economía de plataforma y los impactos que tienen en el espacio público. El hiperespacio juega un papel fundamental en la creación de nuevos capitales sociales y nuevas formas de resistencia a dinámicas creadas por el despotismo intrínseco de los algoritmos. La duplicidad de los espacios que los trabajadores de plataforma, aunque en dimensiones distintas, se mueve hacia la misma dirección. La investigación se concentra en el caso de estudio de la Avenida República del Salvador, de la ciudad de Quito. Sin embargo, aunque el punto de análisis sea esta calle quiteña, el dinamismo del trabajo de plataforma llega a influenciar a la ciudad entera, por lo cual, el área de estudio se expande inevitablemente.
El papel de la universidad en los proyectos estatales de desarrollo: Análisis de los proyectos de Gabriel García Moreno y Rafael Correa
Authors:   PUCESI (Ibarra-Ecuador), Andrade Ortega Alfonsina
Published: June 2022

A partir del siglo XIX cada uno de los gobiernos ha implementado una serie de políticas a través de las cuales se evidencia su visión de desarrollo nacional. Estas visiones, en general han estado articuladas al plano netamente económico. El presente analiza las políticas de desarrollo implementadas por los gobiernos de Gabriel García Moreno y Rafael Correa debido a que, pese a estar separadas por más de un siglo de diferencia, presentan muchas similitudes en la relación que establecen entre Universidad, Estado y Desarrollo. La presente investigación utilizó una metodología exploratoria histórica de los datos, lo que permitió el análisis secuencial de los mismos. El análisis comparativo de estos dos proyectos permitió evidenciar que, durante estos dos gobiernos, la ciencia y la tecnología se convirtieron en un eje fundamental del desarrollo nacional. Por tal motivo, se dio importancia a la articulación de la universidad al proyecto político estatal para transformar la matriz productiva del país. Esto llevó a que la universidad mire y entienda su entorno bajo el filtro del Estado y responda únicamente a sus requerimientos.
Ajwa date (Phoenix dactylifera L.) is hepatoprotective against toxicity by antituberculosis drugs - an experimental study
Authors: Majeed Sadia , Aslam Usman , Zaffar Sehrish , Chiragh Sadia
Published: June 2022

Background and Objective: Hepatotoxicity induced by antituberculosis drugs is quite common and often linked with oxidative stress. Ajwa dates are rich in antioxidants and flavonoids; therefore, these may be protective against the oxidative stress to liver. This study was designed to determine the hepatoprotective effects of Ajwa dates on hepatotoxicity induced by antituberculous drugs in an experimental model.
Methods: This experimental study was conducted at the Post Graduate Medical Institute, Lahore, Pakistan. A total of 30 male rabbits were divided into 5 groups, with 6 animals in each group. Group A and B were fed on normal diet. Group C, D, and E were fed on a diet supplemented with whole Ajwa dates, flesh, and seed powder, respectively. Group B, C, D, and E were given isoniazid 50 mg/kg and rifampicin 100 mg/kg orally for 14 days. After the rabbits were sacrificed, hepatotoxic changes were examined histologically in all groups according to standard criteria.
Results: Liver to body weight ratio was higher in disease group (B) as compared to the healthy control group A (p-value = 0.03), Ajwa flesh group D (p-value = 0.02) and Ajwa seed powder group E (p-value = 0.07). Differences between experimental groups were not statistically significant for both liver weight, and liver weight to body weight ratio. On histological examination, degeneration, necrosis, steatosis, triaditis, and fibrosis were seen in the disease group B while no such changes were observed in group C, D, and E.
Conclusion: Ajwa dates (Phoenix dactylifera L.) has a protective role against isoniazid and rifampicin-induced hepatocellular injury and fibros.

The new facet of healthcare leadership: “Sustainability for NextGen”
Authors: Khan Khalid Rahim , Khalid Ambreen
Published: June 2022

A sustainable healthcare framework implies maintaining both the current and future quality of healthcare through balancing social, environmental and financial constraints. Health care faculties in Medical Universities hold a professional obligation to yield ‘sustainability-oriented’ healthcare leaders, having a sense of eco-accountability, environmental justice, and intergenerational resource equity. For this multipronged diverse approach, the most cardinal contribution, for a sustainability continuum, by the current generation of professionals is to develop a ‘sustainability mindset’ for the healthcare leaders of tomorrow. The ripple effect of the ‘sustainability mindset’, thus created will be the key factor, to traverse through generations to come, for individual health, healthcare systems and most importantly for the planetary health.
Vanadyl(acetylacetonate)2 mediated hydrolytic splitting of 1,3,5-triazine in a solution of toluene at 130 °C: The crystal structure of its axial formamide adduct
Authors: Arslan Evrim , Bernal Ivan , Lalancette Roger
Published: June 2022

A toluene reaction of vanadyl bis(acetylacetonate) with 1,3,5-triazine produces a symmetrical three-fold hydrolytic cleavage of the triazine, and these three formamide moieties are found in the crystal structure. One of the resulting formamides attaches itself to the sixth (axial) position of the vanadyl complex, producing materials in which the remaining two formamides are trapped in the resulting lattice. Those crystals belong in space group Pca21, Z = 4 and the final R-factor = 0.030 for 3213 data collected at 100 K.
Dijital Platformlarda İslâmî İmgeler (Kalifat Dizisi Örneği)
Authors: Çakır Furkan
Published: June 2022

Bireysel düşüncelerini başkalarına aktarma ve hatta empoze etme düşüncesi insanlık tarihi kadar eskidir. Nitekim ilâhî kitabımız, ilk insanların şeytanın söylediği sözlerden etkilenerek kandırıldığını ifade etmiştir. Hz. Peygamber’in insanları doğru yola sevk etmek için tebliğ ettiği ve bu vazifeyi yerine getirmekle görevlendirildiği bilinen bir gerçektir. Asıl itibarıyla insanın olduğu her yerde bu durumun gerçekleşmesi gayet tabiîdir. Fakat tarih boyunca özellikle kültürel ve teknolojik sahadaki ilerlemeler sözü edilen faaliyetlerde kullanılan araçları değiştirmiştir. Örneğin; yazı malzemesinin temininin kolaylaşması ve matbaa alanında gelişmeler yaşanmasıyla fikirler daha çok yazıyla aktarılmıştır. Modern döneme gelince televizyon, bilgisayar ve bunların destekleyicisi olarak internetin geçirdiği dijital değişim ve dönüşümlerle birlikte görsel çalışmalar hız kazanmıştır. Bu doğrultuda televizyon ve akabinde dijital yayın platformları yaygınlaşmış ve hatta dijital platformlara rağbetin artmasıyla medya sektöründe zorunlu bir değişiklik gerekmiştir. Bu değişikliği öngörerek dijital yayın sektörüne hızlı bir giriş yapan ve milyonlarca abone sayısına ulaşan en büyük dijital yayın platformu Netflix’tir. Bilindiği üzere görsel medya uygarlığının tek olmasa da en önemli gayesi ekonomik çıkar elde etmektir. Ancak bununla birlikte Netflix ve benzeri şirketlerin içerikleriyle düşünce dünyalarını, hayatı anlamlandırma yöntemlerini ve hatta ideolojilerini kasıtlı ya da kasıtsız empoze ettiği de muhakkaktır. Bu doğrultuda hem ilgilisi fazla hem de ses getirme etkisi yüksek olduğu için dini imgeler taşıyan program, dizi ve film gibi yayınlara dijital platformlarda büyük oranda yer verilmektedir. Ancak kimi zaman insanların doğru bilgiye ulaşması ve her türlü hurafeden uzaklaşmasına yol açan bu yayınlar, çoğu zaman yanlış bir din öğretisinin aktarılmasına sebep olmaktadır. Sözü edilen platformda son günlerde en çok izlenen içerikler arasında yer alan ve İsveç’ten sözde İslâm Devleti’nin sınırları içerisindeki Rakka’ya giden bir ailenin dram dolu hikâyesini anlatan Kalifat dizisinin, izleyicilerini İslâm öğretileri hakkında farklı şekillerde yönlendirdiği görülmektedir. Çalışmamızda bu dizide yer alan İslâmî imgeler, din istismarı ve İslamofobi gibi başlıklar üzerinden tahlil edilecek ve dijital platformların din algısını ne denli şekillendirdiği üzerinde durulacaktır. Ayrıca değişen medya ve dijital platformların dönüşümüne, dizinin amaç ve hedeflerine uygunluğuna ve IŞİD militanlarının düşünce dünyalarının İslâm’ın esas öğretileriyle ne denli örtüştüğüne de temas edilecektir. Tüm bunların akabinde genelde medya sektöründe özelde dijital platformlarda algı oluşturmanın imkânına vurgu yapılacaktır.
İslâm Devletler Hukukunda Devletin Gayrimüslimlere Ait Mâbetler Hususunda Yürüttüğü Politikanın Dinî mi Yoksa Siyasî mi Olduğu Üzerine Bir İnceleme
Authors: Atcı İsa
Published: June 2022

Müslüman olmayıp belirli şartlar çerçevesinde İslâm devletinin hâkimiyetinde yaşayan insanlara “gayrimüslim” denilmektedir. Hz. Peygamber Medine’ye hicretiyle beraber gayrimüslim toplumla karşılaşmış ve bunlarla ilgili duruşunu “Medine Sözleşmesi” ile net bir şekilde ortaya koymuştur. Sahabe dönemi ile başlayan yoğun fetih hareketleri sonucunda gayrimüslimler İslâm devletinin tebaası olmuştur. Bunlarla ilgili hukukî düzenlemeler gerçekleştirilerek devlet nezdindeki ve toplum içerisindeki statüleri belirlenmiştir. İslâm inancını kabul etmeye zorlanmayan bu insanlara inanç ve ibadet hürriyeti de tanınmıştır. Bununla birlikte bu hürriyetin çerçevesi, İslâm devleti ve Müslüman toplumun maslahatı ile sınırlandırılarak toplumsal güven ve huzur temin edilmiş, bir arada yaşamanın temel parametreleri tesis edilmeye çalışılmıştır. İslâm devletleri, sulh ile alınan yerler ile savaş sonucunda alınan yerlerdeki gayrimüslim mâbetlerini farklı değerlendirmiştir. Sulh ile alınan yerlerde, mâbetlerin yıkılması veya camiye çevrilmesi hususunda gayrimüslim halkın rızası alınırken; savaş ile alınan yerlerde bulunan mâbetler üzerindeki tasarruflarda böyle bir rızaya ihtiyaç duyulmamıştır. İlkesel olarak gayrimüslimlerin fetih öncesi inşâ edilmiş olan mâbetlerine dokunmama ve onları tamir etmeme prensibi hemen hemen bütün dönemlerde korunmuş, yeni mâbet inşâ edilmesine de olumlu bakılmamıştır. İlkesel olarak din ve vicdan hürriyeti kapsamında gayrimüslimler inançlarında serbest bırakılmış ve Müslüman olmaya zorlanmamışlardır. Ancak Müslüman toplumun dinini muhafaza edebilmesi için gayrimüslimlerin din, kültür ve geleneklerini ulu orta yaşamalarına izin verilmediği gibi; mâbetleri hususunda da kısıtlamalar getirilmiştir. Bu bağlamda bazı kiliselerin yıkılması ve mevcut mâbet sayısının azaltılması gibi bir dizi önlem alınmıştır. Buna rağmen zarurî ihtiyaç halinde yeni mâbet inşâsına izin verildiği de olmuştur. Bu durumda mâbetlerin ihtişamlı inşâ edilmesine izin verilmemiş, mimaride bazı ölçülere riâyet etmeleri şart koşulmuştur. Bu çalışmada Hz. Peygamber döneminden başlamak üzere İslâm hukuk tarihinin farklı dönemlerinden bazı uygulama örnekleriyle İslâm devletlerinin gayrimüslimlerin ibadethânelerine yönelik yürüttüğü politikaların dinî mi yoksa siyasî mi olduğu sorusuna cevap aranacaktır. Bu bağlamda İslâm devletinde “zimmî” olarak tanımlanan bu insanların genel hukukî statülerinden ziyade bunlara ait mâbetlerin durumu bu çalışmamızın temelini oluşturmaktadır. Çalışmamız Hıristiyan ve Yahudilere ait mâbetler ile sınırlı tutulmuştur.

The most abundant heavy non-ferrous metals in industrial wastewater and spent solutions are lead, copper, zinc, nickel, however, it depends on the type of the industry. This work proposes the concepts of an electrochemical method of divalent copper removal from spent solutions with help of granular graphite electrodes. The study was conducted changing the meanings of the five major parameters including the current density (i), the concentration of copper (II) ions (C), the surface area of graphite electrodes (S), the concentration of sulfuric acid in the solution (M) and the electrolysis duration (τ) affecting Cu (II) ions removal percentage from solution. Experimental results show that the current density, surface area of the granular graphite electrodes and the time are the main factors that affect the removal percentage of Cu (II), while the changes in sulfuric acid concentration in solution have a minor effect. Highest copper removal value 97% and 54 % current efficiency was observed in conditions: i =150A/m2, τ = 1.5 h, [H2SO4] = 0.4 M, S = 150 cm2 which is considered as an optimal condition for copper removal process by granular graphite electrode.

The leaching of copper-containing raw materials with environmentally friendly reagents under near-environmental conditions is an important problem of modern hydrometallurgy. In this regard this article presents kinetic regularities of leaching of sulfide mineral – chalcocite (Cu2S) using the simplest amino acid – glycine (Gly) in alkaline medium at 25 ºС. It is assumed that the leaching is mainly due to complexation of copper (II) glycinates. The influence of different parameters on the amino acid leaching process such as concentrations of glycine, sodium hydroxide, hydrogen peroxide, reagent ratio and duration of the experiment were studied. The results of atomic absorption analysis indicated a significant increasing of copper recovery efficiency from chalcocite when the oxidant hydrogen peroxide was added to the alkaline glycine solution system. After 30 minutes the degree of copper recovery has reached 30.79 % in the system «Cu2S-0.1M Gly-0.1M NaOH-0.1M H2O2» while without hydrogen peroxide about 4 % of copper has been leached. The research results allow to recommend glycine as a promising reagent for hydrometallurgical copper production process.

The raw material for alcohol production is a variety of plant materials, which contain sufficient amounts of digestible sugars or other carbohydrates that can be saccharified. Dahlias are tuberous plants of the Asteraceae family with a quick and powerful growth and a long vegetation period. The study of the chemical composition of dahlia tubers is of undoubted interest in terms of practical health care. Dahlia tubers are the main raw material for obtaining inulin, which has a wide range of pharmacological action. The vegetative (aboveground) part of dahlia has been an object of research. The purpose of this study has been to study the chemical composition of raw alcohol, obtained from the dahlia tubers. For this purpose, the chemical composition of the tuber of dahlia plants belonging to the Compositae family has been studied. It has been found that the tubers of dahlia contain a large amount of biologically active substances: protein, coumarin, polyphenol, pectin and inulin. Dry alcoholic yeast (TC BY 100104781.010-2005 dried alcoholic yeast Saccharomyces cerevisiae produced in Belarus) has been used as yeast. The fermentation process has taken place at the room temperature for 2-3 weeks. After 2 weeks it has been filtered, the quantity of wort has been measured and distilled. The chemical composition of the raw alcohol, obtained from dahlia tubers has been identified on an Agilent 7890A/5975C chromato-mass spectrometer.

In systems based on bituminous film-forming agents, the adsorption of a surfactant AC-1 at the interface with air and aluminum powder has been studied. The effect of temperature, quantitative contents of the film-forming and initial surfactant concentration on the parameters and mechanism of AC-1 concentration on the interface has been established. The equilibrium indicators of the adsorption of surfactant AC-1 at the interface between the film-forming agent and air were determined (limiting adsorption Г∞, thickness of the adsorption layer δ of the surfactant AC-1 group, landing area S of the functional group of AC-1 surfactants). A decrease in Г∞in 1.5-2.0 times (0.91∙ 10-5mol/m2 with Ĉs = 1.78) and δ (2.80∙10-9÷3.00∙10-9 m) with an increase in temperature from 280 to 310K and solvent concentration up to Ĉs = 1.78. The area S of the occupied amino group in the adsorption layer was 8.50 ∙ 10-20÷10.00 ∙ 10-20 m2. The value of the resulting thermal effect (ΔН) for bituminous compositions with Ĉs = 1.17÷1.78, regardless of the surfactant content, is plus 38-40 kJ/mol;for compositions with a solvent content of 1.78 (ĈSAA = 0.06) with an increase in temperature from 300 to 313 K, there was a decrease in the resulting adsorption index by 1.0 ∙ 10-6mol/m2 and ΔH to a level of 20÷1.5 kJ/mol2.A proportional increase in the adsorption of AC-1 on aluminum powder from the initial concentration of surfactants and an insignificant decrease in the adsorption index in systems more concentrated in bitumen were established.

An annual increase in the consumption of the automobile fuels makes us look for new ways of their obtaining. It is also important that the environmental and operational requirements for the quality of the motor fuels, obtained during oil production (associated petroleum gas, gas condensate) are systematically made more rigorous. One of the ways to solve the problems described above is to use the process of oxidative desulfurization to improve the quality of the petroleum products. In this case, oxidative desulfurization of the straight-run gasoline fraction, obtained from the gas condensate of the Karachaganak field, has been carried out. The oxidation process has been carried out with hydrogen peroxide in the presence of salts of the transition metals, molybdenum and vanadium. The optimal technological parameters (Patm, T=600C, 2 h, H2O2:S=4:1 (mol), Me:S=1:100 (mol)) of the oxidation process for the straight-run gasoline fractions have been selected. Under the optimal conditions of the oxidation process, the total sulfur content has been reduced by 89.9%. It has been shown that the molybdenum compounds exhibit greater activity in the oxidation of sulfur-containing compounds at a temperature of 600C, as compared to the vanadium compounds. A schematic diagram of the purification of the gasoline fractions from the sulfur-containing compounds by oxidative desulfurization, followed by its extraction desulfurization with the most effective N,N-dimethylformamide has been presented.

In this paper, the object of research is an innovative model of regional management of freshwater resources in the context of achieving environmental goals. The study found that the most problematic issues are the lack of clear criteria and methodological mechanisms in the formation of the basic innovative principles of freshwater resource management in the context of sustainable development. When solving the problems posed in the work, the methods of analysis and synthesis, comparative comparison and logical generalization were used. On their basis, the analysis of the main principles of adaptation of the world experience of regional management of freshwater resources in the context of the implementation of the European Union Water Framework Directive was carried out and the conceptual foundations for the formation of an innovative model for the management of freshwater resources of territories in the context of sustainable development were developed. A cluster model of a regional innovation-information portal of freshwater resources is proposed, which allows uniting the efforts of public authorities, the population, the public, scientific institutions and business in solving problematic issues related to the ecosystem based on smart technologies in the context of sustainable development. It is determined that for the functioning of the cluster model it is necessary to develop institutional, legislative, regulatory, scientific and innovative, investment support. It is substantiated that the functioning of the cluster model of the regional innovation-information portal of freshwater resources will solve the following problems:–creation of a unified data bank for monitoring the quality of water resources, the results ofscientific and technical activities, business planning and design for the conservation, restoration and purification of water;–information services in the field of innovation;–attraction of business representatives to co-financing of innovative projects.Thanks to the results of the conducted studies, it is possible to more objectively and balanced assess the possible schemes and tools for managing the territory’s freshwater resources. The conceptual approach presented in the paper is a rather flexible tool with a free choice of elements of analysis depending on the goals and objects of management.
