Moduli spaces of stable sheaves over quasi-polarized surfaces, and the relative Strange Duality morphism
Authors: Makarova Svetlana 
Published: December 2021

The main result of the present paper is a construction of relative moduli spaces of stable sheaves over the stack of quasipolarized projective surfaces. For this, we use the theory of good moduli spaces, whose study was initiated by Alper. As a corollary, we extend the relative Strange Duality morphism to the locus of quasipolarized K3 surfaces.Comment: 15 pages; comments welcome; part of the author's PhD thesis. Published version
Inference from Weak Hadiths in Beliefs from Sunni Scholars
Authors: Muhammad Esmail Allaa Eddin 
Published: December 2021

تعد العقيدة الإسلامية هي أهم علوم الشريعة فبها يدخل الإنسان للإسلام وإذا اختل ركن من أركان العقيدة يخرج الإنسان من الدين، ولذلك ذكر العلماء أن مصادر العقيدة يجب أن تكون ذات موثوقية عالية ولذلك كانت العقيدة الإسلامية مأخوذة من كتاب الله ومما تواتر وصح من قول النبي صلى الله عليه وسلم. وقد قرر علماء العقيدة أن الحديث الضعيف لا يؤخذ به في باب العقائد بل لا بد لتقرير أبواب الإيمان من أن يكون الحديث صحيحاً سالماً لا علة فيه. ولكن هذه القاعدة العامة قد لا يسير العلماء على وفقها في كل الأوقات حيث نجد أنهم في فروع العقيدة كانوا يتساهلون في الاستدلال ببعض الأحاديث الضعيفة. وتأتي الدراسة هنا لتبين مصادر العقيدة وتتحدث عن منهج السلف الصالح في الاستدلال بالحديث الضعيف، وعن ضوابط الأخذ بالحديث الضعيف في العقائد، ثم يذكر الباحث أمثلة من استدلالات العلماء بالحديث الضعيف في تقرير فروع العقيدة الإسلامية، والله الموفق للصواب والحمد لله رب العالمين.

Abstract
The Islamic creed is the most important science of Sharia, through which a person embraces and follows Islam, and if one of the pillars of the creed is missing, then the person steps out of Islam. For this reason, the scholars mentioned that the sources of the creed must be highly authenticated and certified. Therefore, the formation and extraction of Islamic creed is based on al-Quran, and on authentically documented sayings of Prophet Muhammad, may Allah bless him and grant him peace. The creed science scholars and experts have declared that a doubtful and unreliable hadith is not to be taken into account in the science of creed; rather it is necessary to establish the science of creed and its sections that the hadith must be authenticated and attested without having any fault or weakness. However, scholars may not follow this general (but) important rule at all the times, as we find that in the subjects and chapters of creed they used to be lenient in deducing some doubtful and unreliable hadiths. The study comes here to explain the sources of science of creed and to discuss about the approach of the righteous predecessors in deduction and argumentation using doubtful and unreliable hadiths, and about the rules and regulations for adopting weak hadiths in the science of creed. Then the researcher mentions examples of scholars’ argumentation using the weak hadith in establishing the sections of the Islamic faith. And all praises to almighty Allah.

Published: December 2021

Purpose. Examine the formation of quality (biochemical component, vitamin content) of frozen berries and jam from sea buckthorn as affected by varietal characteristics.
Methods. Laboratory, mathematical and statistical, physicochemical.
Results. The main component of frozen sea buckthorn berries is water, 75.5–77.4%. In jam, water content mades up 57.5%. Studies have shown that frozen berries of different varieties contain ash (0.3%), protein (from 0.85 to 0.89), carbohydrates (mono- and disaccharides, 4.5–5.0), fat (5.0– 5.3%). The content of carbohydrates in the jam at the actual humidity was 32.0%, the content of ash and protein was also the lowest, 0.5–0.6%, and the fat content was 3.8%. The carbohydrate content increased due to the addition of sugar during the preparation of the jam. The content of vitamins in frozen sea buckthorn berries varied significantly depending on the variety. Thus, the content of vitamin C in the berries of variety ‘Uliublena’ was 178 mg/100 g, while in the variety ‘Yelyzaveta’ 167 mg/100 g. In sea buckthorn jam, the content of vitamins B9, B3 and E was 46–72% higher compared to berries, apparently due to the reduction of its humidity during cooking. The content of vitamin C decreased to 55.5 mg/100 g, and the remaining vitamins did not change compared to frozen berries. The content of vitamins B9 and B3 decreased by 16%, vitamin C by 82%, and the content of vitamins B7, B1, B2, B6 and B5 by 45–50% compared to frozen berries. The integrated score of 100 g of frozen sea buckthorn berries satisfies this need with vitamin C – 185–197%, depending on the variety. The need for vitamin E is satisfied only by 15.3–16.7%, and the rest of the vitamins – by 0.5–3.8%, depending on the variety of sea buckthorn. The integral rate of 100 g of sea buckthorn jam satisfies the daily requirement of an adult with vitamin C by 61.7%, vitamin E by 28.7%, and the rest of the vitamins by 0.8–4.0%.
Conclusions. The quality of frozen berries significantly depends on the variety of sea buckthorn. Frozen sea buckthorn berries contain the most vitamin C, 167–178 mg/100 g, and jam 55.5 mg/100 g of product. The content of vitamin E is 2.30–2.50 and 4.31 mg/100 g of product, respectively. The content of other vitamins is low, which is confirmed by the analysis of the calculation of the integrated score. The greatest daily requirement of 100 g of frozen berries and jam is provided by vitamin C and E. Therefore it is necessary to use freezing and preparation of jam as sources of vitamin C and E.

Violência de gênero e COVID-19: interseccionalidade e vulnerabilidade da mulher no Maranhão
Authors: Alvares Maria Emília Miranda , Rego Angela Barbara Lima Saldanha 
Published: December 2021

Este trabalho aborda a relação entre pandemia da COVID-19 e os dados veiculados na mídia envolvendo violência de gênero no Estado do Maranhão, entre março e setembro de 2020. O contexto pandêmico vem impactando a vida das pessoas, com reflexos na saúde mental, no aumento do estresse, da convivência conflituosa e das situações de violência. Utilizando como metodologia a análise crítica de dados, em cotejo com as teorias do mandato de masculinidade de Rita Segato e do racismo e sexismo na cultura brasileira de Lélia Gonzalez, constata-se o chamado à mulher para a constante posição do cuidado, ao passo que se torna facilmente descartável no cenário pandêmico. Reflete-se acerca da necessidade de publicização do debate sobre crimes de gênero, contrariamente à crença do senso comum de que se trata de um assunto de foro íntimo, postura comumente referendada pelas instituições de Estado.
