Published: December 2022

Biogas slurry (BGS) is an anaerobic digested organic material that can be used as an organic fertiliser. As cow urine (CU) is rich in plant nutrients, it may be used as diluting agent in biogas production to enhance the fertiliser quality of BGS. To explore the potency of CU on the fertiliser quality of BGS, four experimental trials were constructed by mixing cow dung (CD) and CU in varying proportion designated as T0 (50% CD + 50% Water) as control, T1 (50% CD + 50% CU), T2 (40% CD + 60% CU), T3 (30% CD + 70% CU) for biogas production. The quality of BGS was evaluated by studying its biochemical and microbial properties. The enzymatic activities revealed that all the CU amended samples showed better activities than control and were increased with the increase in CU. Compared to the control, the increase in urease, protease and phosphatase activities were 11.6% to 64.6%, 4.6% to 29.6% and 22.1% to 50.0%, respectively while cellulase activities were decreased from 25.9% to 3.1%. Most of the bacterial populations also increased in CU amended samples; total bacteria (TB) 20% to 60%, phosphate solubilizing bacteria (PSB) 33% to 67% and nitrogen fixing bacteria (NFB) 0% to 33%. Phytohormone, indole acetic acid (IAA) content and glycemic index (GI) were also increased with increase in CU (IAA- 23.5% to 59.5% and GI- 6.2% to 100.5%). With respect to all parameters analysed, CU amended samples can be considered superior to the control one except for their cellulase activities. Thus, utilization of cow urine improves the quality of BGS as organic fertiliser. This finding will help in reducing environmental pollution by utilizing hazardous cow urine as well as improving fertiliser quality of biogas slurry for agronomic use.

Non-alcoholic fatty liver disease (NAFLD) could be diagnosed either by imaging or histology, and laboratory parameters from RFT such as AST, ALT, GGT, as well as UP. In this study, data were collected from Advanced Pathology Sdn. Bhd. The data collected from random population in the year of 2020 were used to identify the association between the parameters of AST, ALT, GGT and UP in presumed NAFLD patients, which are being compared by age, and gender. The results show that the level of GGT was having an insignificant association between gender (p >0.05), but there is a statistically significant association between the age group of respondents (p <0.05). In addition, results from AST indicated that the gender of respondents has a significant relationship with AST (p <0.05), however insignificant correlation between the age group (p >0.05). While for ALT, it proved an insignificant correlation between the gender of respondents (p >0.05), but significant correlated with the age of respondents (p <0.05). Lastly, Chi-square test independence gave a result of p-value = 0.137 (p >0.05), which proved insignificant correlation between gender of respondents and presence of UP andp-value = 0.261 (p >0.05), which proved insignificant correlation between age of respondents and presence of UP.
(Chi-square test, p-value <0.05).

Published: December 2022

Em 2020, o Supremo Tribunal Federal fixou teses a partir do julgamento conjunto dos temas 386 e 1.021, envolvendo o direito às adaptações razoáveis por objeção de crença religiosa. Com o julgamento do tema 386, restou garantida a possibilidade de realização de etapas de concurso em datas e locais diferentes daqueles previstos originalmente em edital. Com o julgamento do tema 1.021, restou garantido o dever do administrador público de disponibilizar obrigação alternativa para seus servidores. Merece atenção das teorias do direito e da justiça o modo como estes direitos foram previstos nas respectivas teses, com forte semelhança ao direito à adaptação razoável que assiste às pessoas com deficiência. Tal como previsto no texto da Convenção Internacional sobre os Direitos das Pessoas com Deficiência, o Supremo introduz os elementos razoabilidade e proporcionalidade, explicitando a existência de limites à busca por segurança e previsibilidade em nome do ideal democrático pluralista.

Authors: ATALAN Ozlem 
Published: December 2022

İnsanlar, İslam dininde, tüm dinlerde olduğu gibi ibadetlerini yapabilecekleri mekânlar inşa etmişlerdir. Bu dini yapılar, plan şemaları ve yapım malzemeleri ile ilerleyen zamanlarda değişime ve gelişime uğramıştır. Tüm dinlerde olduğu gibi, her bir ibadet yapısının farklı isimleri vardır. İslam dininde, camiler Allah’ın evi sayıldığı için, Müslümanlar tarafından kutsal mekanlardır. Camilerin gelişimi, Hz. Muhammed döneminden itibaren ilerleyerek devam etmiştir. Tüm İslam ülkelerindeki camiler, mimari özellikleri ve süslemeleri yönüyle birbirinden farklı özellikler göstermektedir. İslam ülkelerindeki cami yapıları, hem tarihsel kronolojiye göre hem de bölgelere göre farklılıklar taşımaktadır. Osmanlı İmparatorluğu döneminde de dini mimari, Osmanlı kültürünün devamı olarak oluşmuştur. Osmanlı’nın dini mimarisi, yüzyıllar süreci içinde değişim ve gelişim göstermiştir.
Osmanlı döneminde, Manisa 15. yüzyıl ortalarından, 16. yüzyıl sonuna kadar Osmanlı şehzadelerinin saltanata hazırlık yaptıkları bir siyasi kent olmuştur. Manisa’da II. Murad, Fatih Sultan Mehmet, Kanuni Sultan Süleyman, II. Selim, III. Murad, III. Mehmet ve I. Mustafa gibi sultanların içinde olduğu 16 şehzade sancakbeyliğini yürütmüştür. Şehzadelerin Manisa’da yaşadığı süreç içinde, kendileri ve aileleri tarafından pek çok cami, han, hamam, imaret, medrese, sıbyan mektebi, çeşme, hastane, köprü ve kütüphane gibi birçok Osmanlı eseri inşa edilmiştir. Bu eserlerin pek azı günümüze ulaşabilmiştir. Çalışmada, Osmanlı cami mimarisinin gelişim süreci irdelemiştir. Bu bağlamda, Manisa’da yer alan 15. yüzyıl ortalarına ait Hatuniye Camisi’nin mimari özellikleri ile 15. ve 16. yüzyıllarda Manisa’da inşa edilen camiler içindeki yeri araştırılmıştır.

Published: December 2022

Purpose: To find out frequency of cataract in seaside workers and possible factors associated to its development.
Study Design: Cross sectional observational.
Place and Duration of Study: Tyrrhenian coast of Tuscany (Italy), between Rosignano Marittimo and Cecina municipalities in July 2021.
Methods: Ninety-eight seaside workers were selected through convenience sampling technique. All the working subjects selected for this study had a bilateral natural vision equal to or greater than 6/10 in the anamnestic data collection, declared they had not eye diseases in the past and rarely used protective glasses during their work.
Results: The mean age of 98 outdoor workers is 40. Patients with the cataract are older than people without cataract (median 41 vs 38) (p < 0.001) and have a lower visual acuity (0.6 vs 0.7) (p < 0.001); stratifying by job, refraction state and Intra Ocular Pressure (IOP), there aren’t significant association with cataract. The multivariate analysis confirms that age and visual acuity are associated with the development of the cataract (OR 1.99 and 0.01, respectively).
Conclusion: Although senile cataract is an age related disease but Visually significant cataract is seen in persons working outdoors for longer hours.

КОММОДИФИКАЦИЯ ТОПОНИМИИ СОВРЕМЕННОЙ МОСКВЫ В СОЦИОЛИНГВИСТИЧЕСКОМ АСПЕКТЕ
Authors: Соколова Татьяна Петровна 
Published: December 2022

Практика именования и переименования объектов городского пространства (от спортивных стадионов и жилых комплексов до станций метрополитена) в современной Москве позволяет исследовать нейминг как арену экономической и социокультурной борьбы за урбанонимическое пространство. На примере Москвы представляется возможность выявить некоторые механизмы скрытого взаимодействия между различными группами, вовлеченными в процесс топонимической коммерциализации. В частности, в статье раскрывается роль легендарных московских спортивных обществ и футбольных клубов, а также их влиятельных владельцев и деловых партнеров в трансформации городского пространства, в том числе языкового. Рассматриваются также проблемы коммерческого нейминга жилых комплексов Москвы и стратегия «встраивания» искусственно созданных брендов в топонимический ландшафт современной столицы, выявляются последствия коммодификации, которая приводит к социальной поляризации, росту социальной напряженности и дисбалансу в развитии городского пространства Москвы.
The Effect of Lecithin and Horse Serum on the Hemolytic Action of Certain Peptones
Authors: Epstein Albert A. 
Published: December 2022

Abstract
In a preceding communication (1) it was shown that certain peptone fractions cause hemolysis and agglutination of different species of red blood cells. The peptones used in the tests were the individual fractions obtained by separation of Witte's peptone and those arising from the peptic digestion of casein. As stated there, corresponding peptone fractions from the two sources, possess similar properties, although in certain instances the reactions obtained differ in degree.
The hemolysis produced by the peptones is as follows:
Peptone B (Witte) hemolyzes ten species of red blood cells: Human beef, horse, goat, rabbit, guinea-pig, cat, dog, mouse and pig.
Peptone B (Casein) hemolyzes ten species of red blood cells: Human, beef, horse, goat, rabbit, guinea-pig, cat, mouse, goose and pig.
Peptone A (Witte) hemolyzes ten species of red blood cells: Human beef, horse, goat, sheep, rabbit, guinea-pig, dog, goose and pig.
Deuteroalbumose B (Witte) hemolyzes nine species of red blood cells: Human, beef, horse, goat, sheep, rabbit, guinea-pig, cat and goose.
Bacterial Cultures of Human Spleens Removed by Surgical Operation
Authors: Sellards Andrew Watson 
Published: December 2022

Abstract
In recent years, considerable evidence has accumulated which proves that bacteria can be cultivated from the unexposed tissues of the body, especially the lymphatic glands of normal men and the usual laboratory animals. In contrast to these findings, it was formerly assumed that the unexposed tissues of the body are sterile. Absolute freedom of the internal viscera from bacteria would constitute a rather remarkable relationship to our bacterial environment. When we consider the intimate contact of bacteria with skin and more especially the mucous membrane of the alimentary tract, it would be rather unexpected that these structures should form an absolute barrier against the entrance of bacteria. Consequently, it is not surprising to find a fairly definite flora present in the interior of the body under normal conditions.
Cells Involved in the Immune Response
Authors: Abdou Nabih I. , Richter Maxwell 
Published: December 2022

Abstract
Normal bone marrow antigen-reactive cells could be stimulated to commence the sequence of intracellular reactions characteristic of the afferent limb of the immune response by incubation with antigen in vitro in cell culture. Injection of these in vitro-stimulated bone marrow cells, along with antigen, into irradiated immunoincompetent recipients resulted in a reconstitution of the host's immune competence that was characterized by plaque-forming capacity in the spleen cells 7 days later. Recipients of cells irradiated following in vitro incubation with the antigen gave normal immune responses, whereas irradiation of the cells before in vitro incubation with the antigen completely suppressed the capacity of these cells to transfer immunocompetence. Bone marrow cells irradiated in vitro could exclude the trypan blue dye but failed to undergo blastogenesis and mitosis when cultured in the presence of phytohemagglutinin.
Data in support of the clonal selection theory, with respect to the antigen reactive cells (ARC) present in the normal rabbit bone marrow, were also presented. Precommitment of the ARC to one antigen could not be subverted even if the cells were incubated for 24 hr in vitro in the presence of a second non-cross-reacting antigen in high concentration. Therefore, the ARC is unipotential with respect to antigenic specificity.
