Published: July 2022

En el presente trabajo se compara la confiabilidad estructural de un edificio de concreto reforzado destinado a uso de oficinas y ubicado en el suelo blando de la Ciudad de México, utilizando dos sistemas estructurales distintos. El primero es a base de marcos resistentes a momento de concreto reforzado (sistema convencional) y en el segundo se incorporan muros de cortante ubicados estratégicamente en los marcos exteriores (sistema dual). Para las dos edificaciones se utilizan modelos estructurales complejos los cuales son sometidos a varios registros sísmicos del suelo blando con la finalidad de estimar y comparar la confiabilidad de ambos sistemas utilizando curvas de peligro de demanda. Es importante mencionar que también se hace una comparación de los resultados obtenidos del diseño de los dos sistemas estructurales en términos de otros indicadores de demanda ingenieril. El parámetro utilizado para estimar la confiabilidad estructural es la distorsión máxima de entrepiso, la cual se obtiene mediante análisis dinámicos incrementales que permiten la elaboración de curvas de fragilidad sísmica. La estimación de la confiabilidad estructural se hace mediante modelos probabilísticos al combinar las curvas de fragilidad y de peligro sísmico. Finalmente, con los resultados obtenidos se comprueba que utilizar el sistema dual puede ser una buena alternativa de diseño, obteniendo una solución más económica y un mejor comportamiento sísmico.

Published: July 2022

Fenomena budaya bersarung adalah bahasan penelitian yang digali menggunakan pendekatan etnografi. Informan yang terlibat adalah pelaku budaya bersarung dari beragam profesi dan latar belakang. Data diperoleh dari studi pustaka termasuk media online. Sarung adalah busana yang dikenal masyarakat Indonesia sebagaimana di banyak bagian negara lain di Asia. Sarung dipakai untuk menutup tubuh bagian bawah seperti busana adat daerah, mulai dari busana sehari-hari hingga busana pengantin. Barthes (1997) menyatakan busana sebagai pembentuk identitas kolektif sehingga didalamnya terkandung penanda bermakna. Di lain pihak Malcom Barnard (2002) menyebutkan bahwa fungsi busana tidak hanya sebagai pelindung tubuh namun juga sebagai alat komunikasi. Ketika sarung menjadi bagian dari busana sehari-hari, acara adat, ritual keagamaan hingga pernikahan, sarung telah mendukung aktivitas masyarakat maka ini adalah praktek budaya keseharian. Belakangan ini sarung untuk laki-laki maupun perempuan dipopulerkan kembali oleh masyarakat perkotaan khususnya pecinta fesyen. Selain pembiasaan baru tersebut, oleh sekolompok lain masyarakat sarung dibedakan peruntukannya berdasarkan motif. Ada pemahaman bahwa kaum laki-laki hanya pantas menggunakan sarung bila motifnya berciri geometris. Sarung sebagai budaya yang mengandung makna penting bagi masyarakat mewarnai kehidupan fesyen lokal.

An analysis of trends in the development of situation on brucellosis in the world over past decade and the data on the main risk factors for the occurrence of epidemiological complications regarding this infection in various regions of the world are provided in the paper. An expert assessment of the current epizootiological and epidemiological situation on brucellosis, the coverage of population and animals with immunization in the Russian Federation is given. Over 9 months of 2021, 210 potentially hazardous as regards brucellosis in cattle areas and 24 sites – as regards brucellosis in small ruminants – were registered in Russia. Compared to the same period in 2020, there was a decrease in the number of newly identified hazardous sites for bovine brucellosis by 35.8 % (117 areas). However, long-term upward trend in epizootiological adversity for bovine brucellosis in Russia persists. The epidemiological situation on brucellosis in the country for the period of 2012–2021 is characterized as unfavorable. Decrease in the number of newly detected human brucellosis cases (by 25.1 % of long-term average values) is observed against the background of persistent unfavorable epizootic conditions for brucellosis among epidemiologically significant species of small ruminants and cattle in regions with developed animal husbandry. In 2021, clusters of human cases were registered in the Republic of Dagestan and Penza Region. In the Republic of Dagestan, against the background of aggravation of epizootiological and epidemiological situation on brucellosis, there was also an alarming trend towards prevalence of a relatively high incidence among minors. The proportion of cases of brucellosis among children under the age of 17 in the Republic amounted to 60.3 % of the total number of minors with newly diagnosed brucellosis in Russia over the past 10 years. Taking into account current epizootic, epidemic situations and the long-term dynamics of the development of situation on brucellosis in the Russian Federation, the incidence of brucellosis among the population is predicted to be 10–15 % lower than the average long-term values – 0.18–0.20 per 100000 of the population – in 2022. The number of human cases of brucellosis can range from 250 to 300.
The ‘New Humanitarians’: Vernacular aid in Greece
Authors: Maya Adi 
Published: July 2022

Since 2015, the ’refugee crisis’ in Greece has turned the Eastern Mediterranean migration route into one of the main entry points to Europe. In response, a grassroots solidarity movement has emerged in the Aegean islands that has become instrumental for boat rescue at sea, and for camp service provision. These local and international volunteers, as well as refugees, identify as ‘New Humanitarians’. This paper presents the emic aspects of the ‘New Humanitarians’, and focuses on vernacular actors and how they challenge the humanitarian landscape in Greece by examining their principles, practices, and discourse.
A key finding is that the ‘New Humanitarian’ principles that they model revisit the existing ones—i.e. solidarity, hospitality, equality, and agency. Other findings show that the ‘New Humanitarians’ are reproducing governing technologies imposed by the government and other agencies. They do so while trying to contest mainstream humanitarianism and pleading for much-needed change in the European border regime and refugee management systems.

Abstract
Green roof is the roof of a building that is partially or completely enfolded with vegetation and its associated components. It promotes the sustainability of buildings and provides comfort for urban ecosystem. We have investigated the viability of using organic waste as a growing medium. This study determines the most suitable growing substrate by investigating organic wastes of Sawdust, Wood bark, Bio char, Coir, Compost and Base medium under the parameters of density, moisture content, drought resistance and thermal resistance, contribution for vegetation growth, pH, electric conductivity and nutrient constituents. Investigation of chemical parameters is a unique aspect of this study. New methodologies using mathematical concepts were used to find thermal conductivity and EC of specimens in our research. Preliminary study results shows that the most substrate composition will comprise 60% growing medium and 40% base medium (fertilizer + potting mix).During the experimental studies, we have compared the test results of each organic waste specimens under the mentioned physical and chemical parameters. Base medium (90:10) has highest bearing capacity to withstand external loads including vegetation and other imposed loads. Sawdust (60:40) exhibited optimum attributes for lightweight substrate by having least saturated unit weight, dry unit weight and the highest moisture content. In terms of drought resistance and vegetation growth, Bio char (60:40) was exceptional. Wood bark (60:40) exhibited the most convincing thermal resistance. The best characteristics in terms of pH, EC and nutrient content were exhibited by Sawdust (60:40), Coir (60:40) and Compost (60:40) correspondingly. Based on final ratings by considering all the experimental results, Coir (60:40) have emerged as the optimum growing medium in terms of physical and chemical properties. The authors emphasize to utilize this experimental study results into large-scale construction industries to promote the urban ecosystems through sustainable green roof constructions.

Abstract
Traditional wireless data aggregation (WDA) technology based on the principle of separated communication and computation is difficult to achieve large-scale access under the limited spectrum resources, especially in scenarios with strict constraints on time latency (e.g. autonomous driving). To solve this problem, Over-the-Air Computation (AirComp) has emerged as a new fast WDA solution. AirComp can perform ultra-high-speed wireless data aggregation in the scenario of limited communication capacity. In this paper, to overcome the disadvantage of wireless channel propagation, we use reconfigurable intelligent surface (RIS) to assist AirComp. As far as we know, most of the research on AirComp is focused on optimizing aggregation errors. Most edge devices of the Internet of Things (IoT) are battery-powered. Therefore, optimizing the transmit power of devices could prolong the life cycle of nodes and save the system power consumption. In this paper, we aim for minimizing the system transmit power subject to maximum tolerable aggregation error constraint, while ensuring that each device rate meets the minimum rate constraint. Unfortunately, the problem presented is a very tricky non-convex problem. To solve the proposed thorny problem, we propose a two-step optimization method. Specifically, we introduce matrix lifting technology to transform the original problems into semidefinite programming problems (SDP) in the first step and then propose an alternate difference-of-convex (DC) framework to solve SDP subproblems. The numerical results show that RIS-assisted communication can greatly save system power and reduce aggregation error. And the proposed alternate DC method is superior to the alternate SDR method.

Abstract
Genomic instability is a hallmark of most cancers and presumably results from dysfunction of mutator genes. Yet methods to identify the complete catalogue of mutator genes in human and systematic investigations of their roles in cancer are lacking. Here we developed MutaGene to define genes associated with suppression of genomic instability and identified 1534 putative mutator genes based on the TCGA dataset. We observed that cancer patients with deficiency of mutator genes, in contrast to other genes in cancer pathways or DNA repair pathways, were coupled with strong immunogenicity, e.g., elevated neoantigen burden, immune infiltration, and expression of immune checkpoint inhibitors. The results suggest that patients with deficiency of mutator genes may be favorable candidates for immunotherapy due to their elevated mutation burden. We next integrated the mutator gene catalogue with data of cancer patients post immune checkpoint blockade treatment in the MSK-IMPACT cohort. We found that deficiency of mutator genes, particularly the ones suppressing insertion-deletion mutations, predicted strong anti-tumor effects of the immunotherapy and positive clinical outcomes. Taken together, the mutator genes identified in this study enabled fresh insights into genome instability and serve as robust biomarkers for cancer immunotherapy.

Abstract
BackgroundFibrotic interstitial lung disease associates with a considerable symptom burden, deterioration of quality of life, and mortality; thus, Palliative Care is an alternative for symptoms control. The aim was to analyze its effect in the quality of life.MethodsObservational, prospective study that included patients referred to Palliative Care. Demographic data, baseline functional capacity, symptoms intensity, and quality of life were registered through unidimensional and multidimensional scales before the intervention and then at 30- and 90- days ups. The primary outcome was to analyze the score change through an analysis of variance.ResultsFourteen patients were included with a median age of 63 years (Interquartile Range 54–71), 85% were women. Baseline evaluation confirmed a moderate functional impairment (Karnofsky 65, Interquartile Range 50–70) and deterioration of quality of life (Saint George´s Respiratory Questionnaire-I, 91 points, Interquartile Range 84–96). Frequent baseline symptoms documented by the Edmonton Symptom Assessment System were cough, dyspnea, tiredness, anxiety/depression, and pain. After 90 days of Palliative Care, a significant improvement was observed both in symptoms control and quality of life, based on a 20-point decrease in Saint George´s Respiratory Questionnaire-I (p = 0.008).ConclusionsThe Palliative Care intervention improves symptoms control, and the quality of life patients perceive.

Published: July 2022

Abstract
Background: Spine disorders are becoming more prevalent in today’s ageing society. Motion abnormalities have been linked to the prevalence and recurrence of these disorders. Various protocols exist to measure thoracolumbar spine motion, but a standard multi-segmental approach is still missing. This study aims to systematically evaluate the literature on stereophotogrammetric motion analysis approaches to quantify thoracolumbar spine kinematics in terms of measurement reliability, suitability of protocols for clinical application and clinical significance of the resulting functional assessment. Methods: Electronic databases (PubMed, Scopus and ScienceDirect) were searched until February 2022. Studies published in English, investigating the intersegmental kinematics of the thoracolumbar spine using stereophotogrammetric motion analysis were identified. All information relating to measurement reliability; measurement suitability and clinical significance was extracted from the studies identified. Results: Seventy-four studies met the inclusion criteria. 33% of the studies reported on the repeatability of their measurement. In terms of suitability, only 35% of protocols were deemed suitable for clinical application. The spinous processes of C7, T3, T6, T12, L1, L3 and L5 were the most widely used landmarks. The spine segment definitions were, however, found to be inconsistent among studies. Activities of daily living were the main tasks performed. Comparable results between protocols are however still missing. Conclusion: The literature to date offers various stereophotogrammetric protocols to quantify the multi-segmental motion of the thoracolumbar spine, without a standard guideline being followed. From a clinical point of view, the approaches are still limited. Further research is needed to define a precise motion analysis protocol in terms of segment definition and clinical relevance.

Published: July 2022

Abstract
Systematic study on the microstructural evolution and mechanical properties of ferritic stainless steel (FSS) 430 with different annealing processes were carried out in the present work. The results show that microstructural refinement can be achieved by optimization of annealing processes, improving elongation, yield strength and tensile strength of FSS 430. An optimal annealing temperature of 950 ℃ is found with better homogeneity and enhanced mechanical properties among the cold-rolled and annealed FSSs. During annealing processes, the fraction of high angle grain boundaries of FSS 430 annealed at 950 ℃ is found to be the highest, indicating that a homogeneous microstructure with high recrystallization rate is formed inside the FSS 430 strips. In addition, high fraction of the hard grains (SF < 0.4) and low fraction of the soft grains are found inside FSS 430 annealed at 950 ℃, improving the plasticity of material. Overall, the optimization of annealing processes benefits the microstructural refinement of FSS and thereby improving the mechanical properties of materials.

Abstract
During recent decades, focus has increased on biodiesel production from wastes or other nonedible resources. The high expense of the manufacturing process is one of the major obstacles it faces. So, continuous research for cheaper and safer resources is more important. Seed oil from various vegetables and fruit species has garnered a lot of: attention recently in the production of biodiesel, such as date palm. The date palm is. one of the most. popular fruits in the Middle East Egypt has recorded now as the highest countries production of dates. The oil of date seeds (DSO) has high concentrations of fatty acids and minerals. In biodiesel production, lipid extraction is an important step. But the advanced extraction techniques are preferred to protect human health and the environment. Therefore, the demand for innovative and environmentally friendly products is now necessary. Transesterification is the process in which oils (mostly triglycerides) bond with alcohol in the existence of a catalyst to form an alkyl ester. Synthesizing the green catalyst and utilizing it in the manufacture of biodiesel have a great added value. The high yield of biodiesel supports the catalyst suitability for the transesterification reaction. Immobilized lipase, moreover, plays a critical function in the transesterification process, that it is more effective and safer. DSO is being studied to see if its fatty acid profile or physicochemical properties suggest it could be a suitable biodiesel source.
