No full textLa doctrina malikí sobre esclavitud y el Miray de Ahmad Baba
No full textLa obra Miray al-s. uud, del alfaquí de Tombuctú Ah. mad Baba (1556-1627), perteneciente a la escuela jurídica malikí, es una fatwà u opinión legal en el marco de la jurisprudencia islámica, que aborda la cuestión de los esclavos negros (sudan) que reclamaban la libertad en los mercados del norte de África, por haber sido capturados siendo musulmanes, algo que no está permitido en el islam. De acuerdo con el Derecho islámico clásico, sólo los no musulmanes que no cuenten con la protección de un pacto o del estatuto de lad imma, pueden ser esclavizados. Ah. mad Baba reitera esta doctrina en el Miray, haciendo hincapié en que, de acuerdo con la religión islámica, no existe ninguna relación entre el color de la piel y la esclavitud, y que los negros que habitan el bilad al-sudan (el África occidental premoderna) no son esclavos por naturaleza. Además, como medio para evitar la esclavización de musulmanes libres procedentes del África occidental premoderna, el autor lleva a cabo una clasificación de los pueblos que, en su época, han adoptado o no el islam en este ámbito geográfico, un sistema que plantea serias debilidades estructurales a la hora de llevar a cabo su fin, quizá también intencionadas.
The work Miray al-s. uud, written in 17th century Timbuktu by Ah. mad Baba (1556- 1627), an Islamic scholar that adhered to the Malikí law school, is a fatwa or legal opinion that addresses the issue of the black (sudan) slaves that claimed their freedom in the markets of North Africa, for having been captured while being Muslims, something not allowed in pre- Modern Islamic law. According to it, only infidels without the protection of a pact or of the dhimma status can be legally enslaved. Ah. mad Baba repeats this doctrine, while emphasising that the black skin colour has nothing to do with slavery in islam, and that the peoples of pre-Modern West Africa (bilad al-sudan) are not slaves by nature. Besides this, and as a means of preventing the capture and sale of free African Muslims, the author classifies the peoples of sub- Saharan Africa according to their adherence (or lack of) to islam, a system that, however, could be hardly put into practice, as perhaps intended by the author himself
An Updated View of the Effect of Probiotic Supplement on Sports Performance: A Detailed Review
No full textPurpose of ReviewModulation of the host microbiota through probiotics has been shown to have beneficial effects on health in the growing body of research. Exercise increases the amount and diversity of beneficial microorganisms in the host microbiome. Although low- and moderate-intensity exercise has been shown to reduce physiological stress and improve immune function, high-intensity prolonged exercise can suppress immune function and reduce microbial diversity due to intestinal hypoperfusion. The effect of probiotic supplementation on sports performance is still being studied; however, questions remain regarding the mechanisms of action, strain used, and dose. In this review, the aim was to investigate the effects of probiotic supplements on exercise performance through modulation of gut microbiota and alleviation of GI symptoms, promotion of the immune system, bioavailability of nutrients, and aerobic metabolism.Recent FindingsProbiotic supplementation may improve sports performance by reducing the adverse effects of prolonged high-intensity exercise.SummaryAlthough probiotics have been reported to have positive effects on sports performance, information about the microbiome and nutrition of athletes has not been considered in most current studies. This may have limited the evaluation of the effects of probiotic supplementation on sports performance.Trakya UniversityThe figure and table produced by Miray Nur Aykut (first author) are original
Dosage delivery of chiral ruthenium catalysts using non-ionic surfactants for asymmetric transfer hydrogenation reactions in aqueous media
No full textIn this study, non-ionic surfactants, namely Synperonic (R) F108 and Tween (R) F108, were used as media to dissolve [RuCl(p-cymene)(R,R)-Ts-DPEN] for the dosage delivery and recycling of chiral ruthenium catalysts in asymmetric transfer hydrogenation reactions of ketones in water. The non-ionic surfactant-based catalytic systems bearing ruthenium catalysts in microgram scale can be used directly to conduct transfer hydrogenation reactions in nano-sized micelle structures (60-90 nm) in water under an air atmosphere. The micellar catalyst in the aqueous phase can be recycled from the reaction mixture and can be used up to 8 times in asymmetric transfer hydrogenation reactions of acetophenone

Role of formulation additives on the properties of thermoplastic polyether ester elastomer-based and carbon fabric-reinforced multilayer composites
No full text© The Author(s) 2022.In this study, multilayer carbon fabric-reinforced composites (CFRC) were manufactured by compression molding technique with the combination of carbon fabric and thermoplastic polyether ester elastomer (TPEE) composites. The TPEE-based polymer layers were prepared as binary, ternary, and quaternary composites using carbon black (CB) or N-(β-aminoethyl)-γ-aminopropyl-trimethoxysilane (AEAP) modified carbon black (mCB), ethylene-glycidyl methacrylate copolymer (EGMA) and/or paraffin oil. The effects of formulation additives on multilayer CFRC were investigated in terms of their mechanical, electrical resistivity, electrically stimulated shape memory properties and morphologies. Tensile modulus of neat TPEE included multilayer CFRC increased slightly with the addition of both mCB and oil to TPEE. The highest impact strength of 112.2 kJ/m2 was obtained for TPEE-mCB-EGMA-Oil containing CFRC multilayer composites, which was 30% higher than CFRC with neat TPEE. All modified and reinforced CFRC exhibited higher electrical conductivities than neat TPEE containing CFRC. Electrically triggered bending test showed that combination of TPEE, mCB, EGMA and oil together with carbon fabric in multilayer structure revealed 80% shape recovery ratio within less than 2 min

One ofthe usage is the fill areas. However, it has been thought that using of natural data is notconsidered in architectural design while landfills were planning. Wind is a naturalelement that directly affect the quality of life. It has been seen that the wind, should beincluded in design studies as a determining element in the design criteria. Otherwise,open spaces become uncomfortable. It has been suggested that landfills of Maltepecoastal areas have different climatic data before being filled. It has been thought that theutilization rate of coastal areas decrease comparing usage of unfilled areas. It has beenshowed with two-year individual observations that the rate changes according to usersand climate.The aim of the project is to reveal the problem that the usage rate in Maltepe/İstanbulfill area changes depending on the wind intensity. In this study filling area examined interms of wind speed and determined the intensity of usaged. According to obtaineddatas, the speed of the wind above 5 m/s in the open area is taken as the threshold value at where the user is disturbed. Methods and materials;?

Bu değerlendirme sonucunda, çalışma mimarlık bina bilgisi alanında yapıldığından örneklerin analizinde yerleşim ve mekansal ölçeklerine odaklanılmış, örneklerin tasarım kriterleri tespit edilmiş ve örnekler hem literatürdeki kriterlerle hem de birbiriyle karşılaştırılmıştır. Bu değerlendirmeler sonucunda, Türkiye’de evsizler için üretilecek modüler yaşam birimlerinin tasarım kriterlerine yönelik öneriler geliştirilmiştir. Bu çalışmanın, gelişmekte olan ülkeler için mimari açıdan örnek teşkil edebileceği ve Türkiye’de belediyeler ve merkezi yönetim için uygulanabilirlik konusunda bir rehber olabileceği öngörülmektedir.Homelessness is one of the most significant problems encountered on a global scale today, and this situation has reached the level of a potential threat in Türkiye as well. It is observed that the number of homeless persons is increasing gradually around the world, and it is thought that studies related to homelessness will gain importance. It is seen that various institutions and organizations have successful practices and effective policies to solve the homelessness problem in developed countries. These studies are the applications that guide the design and implementation process of the homeless living units to be designed in terms of architecture. It is believed that there is a need for architectural studies for the homeless persons in Türkiye. The aim of this research is to examine the problem of homelessness from an architectural perspective, to determine the design criteria of modular living units to be developed for the homeless, and to develop suggestions for architectural projects to be produced for the homeless in Türkiye. In the thesis, within the scope of literature research, first of all, project site, spatial, and structural scale criteria for the design criteria of modular living units for the homeless were determined, and the analysis framework was created. In this context, along with the project samples of modular living units produced for the homeless in developed countries and in design stage, the project in design stage of the author was included in the analysis, and a total of eight samples were evaluated in the context of the determined criteria. As a result of this evaluation, as the study was carried out in the field of architectural building design and theory, the analysis of the samples focused on project site and spatial scales, the design criteria of the samples were determined, and the samples were compared both with each other and the criteria in the literature. As a result of these evaluations, suggestions have been developed for the design criteria of modular living units to be produced for the homeless in Türkiye. It is envisaged that this study can set an architectural sample for developing countries as a guide on applicability for municipalities and central government in Türkiye
