Reflexões sobre os vinte anos de experiência do grupo de teatro Tá na Rua

O artigo trata dos conceitos de um teatro público e de um teatro privado, a partir do surgimento da burguesia capitalista. O capitalismo estabeleceu um conflito entre as manifestações públicas (festas dramáticas) e o teatro de recinto fechado. As fontes brasileiras para um teatro público são vistas pela restauração e recuperação das nossas origens mediterrâneas em oposição ao pensamento protestante da América do Norte e Europa

Review on multi-agent system collaboration in learning management system domain by deploying wireless sensor networks for student location detection

Student location detection in Learning Management System (LMS) by utilizing Multi-Agent System (MAS) which contains sensor nodes is a new area of research. This study reviews several studies to ascertain the potential of integrating these two technologies to automate students’ class attendance in Higher Learning Institutions (HLIs). Currently, the HLIs are using paper-based process to record students’ attendance in the class, that is time consuming and is not possible to monitor students all the time, that they suppose to be in learning environment. Introducing the sensor networks and MAS in LMS system is to enable the instructors or lecturers to be aware of the presence of their students once they reach the system’s domain. The collaboration using MAS facilitates the retrieval and recording of students’ details from the sensors and then sends them to LMS servers through Cluster Head Sensor. The information that is collected and recorded by the agents include the signal strength of the students’ device and their profiles which can facilitate to know the exactly locations of the students, by comparing such information with the information already stored in LMS database. Therefore, a system architecture that comprises MAS with sensor networks in LMS is presented in this study for monitoring students’ attendance in the classes and labs. This type of system architecture with improved LMS features is more focused and intended for HLIs that follow the blended learning system. This proposed system has potential of boosting learning process in HLIs by providing new feature in LMS that monitor students’ activities in blended systems, that support classroom and online teachings

The Theatrical Performance Space and its Mechanisms in Ali Abdulnabi Al-Zaidi’s Texts

يسعى المخرج المسرحي في بحثه الدائم عن نصوص معاصرة تعالج قضايا الواقع إلى اختيار النصوص التي تمنحه القدرة على الخيال وتكوين مشهدي يثير المتفرجين ويجذبهم إلى العرض المسرحي بإيجاد فضاء سينوغرافي يقوم بتشكيله فنان السينوغرافيا الذي يقع على عاتقهُ ترجمة الرؤية الإخراجية للمخرج بواسطة المؤثر البصري والتشكيل الصوري للعرض، وهنا ما ينطبق على نصوص الكاتب العراقي علي عبد النبي الزيدي المسرحية؛ لأنها تترك للمخرج وفنان السينوغرافيا المجال الواسع والحرية الكاملة لتقديم عرض بصري تتوازن فيه التكوينات الدرامية مع التكوينات السينوغرافية، وهنا من أهم ما يميز نصوص الزيدي لأنها ذات حيوية عالية وتحتوي على تشكيلات ادائية تجذب المخرجين والسينوغرافيين على حد سواء. وبذلك جاء البحث في أربعة فصول؛ الأول: احتوى على مشكلة البحث واهميته والحاجة إليه وهدف البحث الذي تلخص في السؤال التالي (ماهي الآلية التي عمل عليها السينوغرافيون في تقديم فضاء العرض المسرحي في نصوص علي عبد النبي الزيدي المسرحية؟) وحدود البحث وتعريف المصطلحات، أما الفصل الثاني فجاء بمبحثين؛ الأول: (مفهوم الفضاء المسرحي (السينوغرافيا)) والثاني: (السينوغرافيا في المسرح العربي) ثم مؤشرات الإطار النظري، والفصل الثالث: وهو فصل الإجراءات وتحليل العينة وهي عرض مسرحية (واقع خرافي) إخراج جواد الأسدي 2012. والفصل الرابع وهو فصل النتائج والاستنتاجات، وبعده مصادر البحث ومراجعه.In his constant search for contemporary texts that address issues of reality, the theatrical director seeks to choose texts that give him the ability to imagine and create a scene that excites the spectators and attracts them to the theatrical show by finding a scenographic space formed by the scenography artist, who is responsible for translating the directory vision through visual effect and image formation for the show. This is applied to the texts of the Iraqi playwright Ali Abdulnabi Al-Zaidi, because it leaves for the director and the scenographer a wide scope and complete freedom to present a visual show in which the dramatic formations are balanced with the scenographic formations. One of the most important features of Al-Zaidi’s texts is that they have high vitality and contain performance formations that attract both directors and Scenographers. Therefore, the research is in four chapters. The first one includes the research problem, its importance and need and the research goal which is summarized  in the following question: What is the mechanism by which the Scenographers have worked to present the space of the theatrical show for Ali Abdulnabi Al-Zaidi's theatrical texts? It also includes the research limits and terms definition. The second chapter contains two topics. The first one is the concept of the theatrical space (Scenography) and the second one is the scenography in Arab theatre. They followed by the indications of theoretical framework. The third chapter tackles the procedures and analysis of sample which is the play (Fabulous Reality) directed by Jawad Al-Asadi (2012(. The fourth chapter includes results, conclusions and reference

Proanthocyanidin Attenuation of Oxidative Stress and NF- κ

Hyperlipidemia and hyperglycemia result in oxidative stress and play a major role in the development of diabetic nephropathy (DN). We explored the effects of proanthocyanidin (PA) on the induction and progression of DN in apolipoprotein E-deficient mice. Diabetes Mellitus was induced in ten-week-old male apoE−/−mice using streptozotocin (STZ). Mice were fed with a high-fat diet in presence or absence of PA. PA treatment significantly reduced the high cholesterol levels, restored renal functions, and reduced albuminuria in the PA-treated diabetic mice compared with the diabetic untreated mice. In addition, the glomerular mesangial expansion in the diabetic mice was attenuated as a result of PA supplementation. Moreover, PA treatment restored the elevated levels of MDA and CML and the reduced activity of SOD and GSH in the diabetic mice. Furthermore, PA feeding reduced the activation and translocation of NF-κB to the nucleus compared with the diabetic untreated animals. Reduction of NF-κB activation resulted in the attenuation of the expression of IL-6, TGFβ, and RAGE which protected PA-treated mice against DN. The renoprotective effects of PA were found to be time independent regardless of whether the dietary feeding with PA was started pre-, co-, or post-STZ injection. In conclusion, part of the beneficial effects of PA includes the disruption of the detrimental AGE-RAGE-NFκB pathways

Artificial intelligence-based regional flood frequency analysis methods : a scoping review

Flood is one of the most destructive natural disasters, causing significant economic damage and loss of lives. Numerous methods have been introduced to estimate design floods, which include linear and non-linear techniques. Since flood generation is a non-linear process, the use of linear techniques has inherent weaknesses. To overcome these, artificial intelligence (AI)-based non-linear regional flood frequency analysis (RFFA) techniques have been introduced over the last two decades. There are limited articles available in the literature discussing the relative merits/demerits of these AI-based RFFA techniques. To fill this knowledge gap, a scoping review on the AI-based RFFA techniques is presented. Based on the Scopus database, more than 1000 articles were initially selected, which were then screened manually to select the most relevant articles. The accuracy and efficiency of the selected RFFA techniques based on a set of evaluation statistics were compared. Furthermore, the relationships among countries and researchers focusing on AI-based RFFA techniques are illustrated. In terms of performance, artificial neural networks (ANN) are found to be the best performing techniques among all the selected AI-based RFFA techniques. It is also found that Australia, Canada, and Iran have published the highest number of articles in this research field, followed by Turkey, the United Arab Emirates (UAE), India, and China. Future research should be directed towards identification of the impacts of data quantity and quality, model uncertainty and climate change on the AI-based RFFA techniques

Potential for conservation agriculture in the dry marginal zone of central Syria: A preliminary assessment

This paper reports on early soil related outcomes from conservation agriculture (CA) benchmark sites located within the marginal rainfed environment of agro-ecological zone 4 (annual rainfall: 200–250 mm) in pre-conflict central Syria. The outcomes reported are specifically those that relate to beneficial soil quality and water retention attributes relative to conventional tillage-based soil management practices applied to the fodder barley–livestock system, the dominant system in the zone. On-farm operational research was established to examine the impact of a barley (Hordeum vulgare) and vetch (Vicia sativa) rotation intercropped with atriplex (Atriplex halimus) and salsola (Salsola collina), under CA and conventional tillage agriculture, on the soil quality parameters and crop productivity. Preliminary results showed that CA had a positive effect on the soil quality parameters and crop performance. The soil moisture and hydraulic conductivity were higher under CA (p < 0.05), combined with improved productivity (grain and above-ground biomass) under specific crop mixes. The results suggest that despite the marginal nature of the zone, the use of CA is a viable option for the future of farmers’ livelihoods within similar localities and agro-climates, given the benefits for soil moisture and grain and straw productivity. In addition, it is likely to positively impact those in marginal environments where both pastoralism and agro-pastoralism production systems co-exist and compete for crop biomass as a main source of livestock feed. The increase in grain and straw yields vis-à-vis improvements in biophysical parameters in the CA system relative to tillage agriculture does suggest, however, that the competition with livestock for biomass is likely to reduce over time, and farmers would be able to return increased levels of straw (as stubble and residue) as mulch, given improved biomass yields

Adaptive design model on heterogeneous Learning Management System (LMS) by utilizing Multi-Agent System (MAS)

Content synchronization in LMS(Learning Management System) is a new area of research which involves the transfer of data from one machine to another. Many researchers have conducted their researches concerning synchronization in different applications on data transfer. Therefore, in this paper we introduce a new idea of synchronization in heterogeneous LMSs and to share learning contents among different learning institutions. The major contribution in this paper, is based on the integration of rsync with MAS (Multi-Agent System) in heterogeneous learning management systems (LMSs) environment using SCORM (Sharable Content Object Reference Model), so as different learning in stitutions in higher education (HE)can seamlessly share learning contents in the different LMSs. Hence, a new model of heterogeneous LMS(HLMS)has been presented for easily sharing of learning contents in Higher Learning Institutions (HLI)

Cyclic Alopecia and Abnormal Epidermal Cornification in Zdhhc13-Deficient Mice Reveal the Importance of Palmitoylation in Hair and Skin Differentiation

Many biochemical pathways involved in hair and skin development have not been investigated. Here, we reported on the lesions and investigated the mechanism underlying hair and skin abnormalities in Zdhhc13skc4 mice with a deficiency in DHHC13, a palmitoyl-acyl transferase encoded by Zdhhc13. Homozygous affected mice showed ragged and dilapidated cuticle of the hair shaft (CUH, a hair anchoring structure), poor hair anchoring ability, and premature hair loss at early telogen phase of the hair cycle, resulting in cyclic alopecia. Furthermore, the homozygous affected mice exhibited hyperproliferation of the epidermis, disturbed cornification, fragile cornified envelope (CE, a skin barrier structure), and impaired skin barrier function. Biochemical investigations revealed that cornifelin, which contains five palmitoylation sites at cysteine residues (C58, C59, C60, C95, and C101), was a specific substrate of DHHC13 and that it was absent in the CUH and CE structures of the affected mice. Furthermore, cornifelin levels were markedly reduced when two palmitoylated cysteines were replaced with serine (C95S and C101S). Taken together, our results suggest that DHHC13 is important for hair anchoring and skin barrier function and that cornifelin deficiency contributes to cyclic alopecia and skin abnormalities in Zdhhc13skc4 mice

Work-Life Balance Starts with Proper Deadlines and Exemplary Agencies

Diversity, equity and inclusion (DEI) programs can only be implemented successfully if proper work-life balance is possible in Heliophysics (and in STEM field in general). One of the core issues stems from the culture of "work-above-life" associated with mission concepts, development, and implementation but also the expectations that seem to originate from numerous announcements from NASA (and other agencies). The benefits of work-life balance are well documented; however, the entire system surrounding research in Heliophysics hinders or discourages proper work-life balance. For example, there does not seem to be attention paid by NASA Headquarters (HQ) on the timing of their announcements regarding how it will be perceived by researchers, and how the timing may promote a culture where work trumps personal life. The same is true for remarks by NASA HQ program officers during panels or informal discussions, where seemingly innocuous comments may give a perception that work is expected after "normal" work hours. In addition, we are calling for work-life balance plans and implementation to be one of the criteria used for down-selection and confirmation of missions (Key Decision Points: KDP-B, KDP-C).Comment: White paper submitted to the Decadal Survey for Solar and Space Physics (Heliophysics) 2024-2033; 6 page
