The range of the disease is broad but among hospitalized patients with COVID-19 are coagulation disorders, pneumonia, respiratory failure, and acute respiratory distress syndrome (ARDS). The excess production of early response proinflammatory cytokines results in what has been described as a cytokine storm, leading to an increased risk of thrombosis, inflammations, vascular hyperpermeability, multi-organ failure, and eventually death over time. As the pandemic is spreading and the whole picture is not yet clear, we highlight the importance of coagulation disorders in COVID-19 infected subjects and summarize it. COVID-19 infection could induce coagulation disorders leading to clot formation as well as pulmonary embolism with detrimental effects in patient recovery and survival. Coagulation and inflammation are closely related. In this review, we try to establish an association between virus infections associated with innate immune activation, inflammation and coagulation activation.Keywords: COVID-19, coagulation disorders, TLR3, tissue factor Date A point or period of time associated with an event in the lifecycle of the resource 2020 Subject The topic of the resource covid-19, coagulation disorders, TLR3, Tissue factor Source A related resource from which the described resource is derived Biotemas Publisher An entity responsible for making the resource available Universidade Federal de Santa Catarina Coverage The spatial or temporal topic of the resource, the spatial applicability of the resource, or the jurisdiction under which the resource is relevant Pathology http://socictopen.socict.org/files/original/6a979bbf481dd68ce939513745e1fd79.pdf 4de87af820a2a8744af90fe5caeb8744 Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

Title A name given to the resource The experience of distance learning in the bologna process countries during the COVID-19 pandemic Creator An entity primarily responsible for making the resource Bitieva Zarina R., Bulavina Maria A., Bitieva Zalina R. Description An account of the resource In this article, the authors analyze various aspects of the distance learning discourse of the countries participating in the Bologna Process from the point of view of the impact of the pandemic on the development of higher education. The author pays special attention to the practical aspects of the activities of Russian universities during the pandemic, their interaction with each other and the problems of cooperation in the context of distance learning. Naturally, the stress caused by the epidemic and the transition to distance learning, especially for senior teachers, could not but affect the quality of training, but competently and professionally selected materials provided students with an educational result, and teachers with positive feedback and opportunities for self - development. The aim of the article is to demonstrate the experience of distance learning in the context of the pandemic and its impact on the higher education system. The author used the following methods: comparative research; methods of collecting empirical information; conceptual and terminological analysis; a method for solving problems. The results of the study can certainly be considered as revealing the positive dynamics of the development of the Bologna process in the higher education system, especially in the context of the pandemic.

Title A name given to the resource Spatial patterns of Bovine Corona Virus and Bovine Respiratory Syncytial Virus in the Swedish beef cattle population Creator An entity primarily responsible for making the resource Björkman Camilla, Beaudeau François, Alenius Stefan, Frössling Jenny Description An account of the resource Abstract Background Both bovine coronavirus (BCV) and bovine respiratory syncytial virus (BRSV) infections are currently wide-spread in the Swedish dairy cattle population. Surveys of antibody levels in bulk tank milk have shown very high nationwide prevalences of both BCV and BRSV, with large variations between regions. In the Swedish beef cattle population however, no investigations have yet been performed regarding the prevalence and geographical distribution of BCV and BRSV. A cross-sectional serological survey for BCV and BRSV was carried out in Swedish beef cattle to explore any geographical patterns of these infections. Methods Blood samples were collected from 2,763 animals located in 2,137 herds and analyzed for presence of antibodies to BCV and BRSV. Moran's I was calculated to assess spatial autocorrelation, and identification of geographical cluster was performed using spatial scan statistics. Results Animals detected positive to BCV or BRSV were predominately located in the central-western and some southern parts of Sweden. Moran's I indicated global spatial autocorrelation. BCV and BRSV appeared to be spatially related: two areas in southern Sweden (Skaraborg and Skåne) had a significantly higher prevalence of BCV (72.5 and 65.5% respectively); almost the same two areas were identified as being high-prevalence clusters for BRSV (69.2 and 66.8% respectively). An area in south-east Sweden (Kronoberg-Blekinge) had lower prevalences for both infections than expected (23.8 and 20.7% for BCV and BRSV respectively). Another area in middle-west Sweden (Värmland-Dalarna) had also a lower prevalence for BRSV (7.9%). Areas with beef herd density > 10 per 100 km2 were found to be at significantly higher risk of being part of high-prevalence clusters. Conclusion These results form a basis for further investigations of between-herds dynamics and risk factors for these infections in order to design effective control strategies.

Title A name given to the resource HOW TO BUILD ROBUST ON-LINE JOB INTERVIEW RESISTANT TO HEALTH-RISK GENERATED CRISES Creator An entity primarily responsible for making the resource Blagica Novkovska, Violeta Milenkovska Description An account of the resource After the onset of COVID-19 pandemic and observed its extreme negative effect on the economy, it becameclearly visible that the creation of an employees recruitment system avoiding the physical obstacles present inhealth-risk crises is indispensable for keeping the attained company progress level. Current stauts of the issueof use of online interviews in recruitment process is discussed in this paper from various aspects. Qualitativeand quantitative anlaysis of the importance of online interviews and possibilities for their development ispresented. Organization of the recruitment process involving online interviews with using sophisticated ICTanalysis tools is proposed. The possibility for the small and medium companies to use such a system wasconsidered. Involvement of third party services is identified as a working solution for building a stablerecruitment process system. It is expected such approach to lead to creation of robust interviews systemsresistant to sudden shocks, particularly health-generated cryses.

Title A name given to the resource Global warming and avian occupancy of hot deserts: a physiological and behavioral perspective Calentamiento global y ocupación de desiertos cálidos por aves: una perspectiva fisiológica y conductual Creator An entity primarily responsible for making the resource BLAIR WOLF Description An account of the resource Avian adjustments to desert environments are characterized by an integration of behavior and physiology. These responses serve to maintain homeostasis and conserve vital resources such as water. The small size of birds confers a close coupling to the thermal environment and demands rapid adjustments to environmental challenges. Physiological responses to heat stress include hyperthermia, and increased evaporative cooling as environmental temperatures approach body temperature. Behaviorally, desert birds respond to heat stress by drastically reducing activity during the hottest parts of the day and selecting cool shaded microsites. This characteristic behavioral response presents a potential problem in the face of global warming. If birds totally forgo foraging during extremely hot periods, increased evaporative water loss rates due to higher environmental temperatures could lead to significant episodes of direct mortality for birds in these regions. A simple model is presented which integrates behavior and physiology to predict survival times based on dehydration tolerance, microsite selection and environmental temperature.Los ajustes de las aves a ambientes desérticos se caracterizan por la integración de la conducta y fisiología. Estas respuestas permiten mantener la homeostasis y conservar recursos vitales como el agua. El pequeño tamaño de las aves las acopla al ambiente térmico de un modo estrecho y demanda que ellas muestren respuestas rápidas a los desafíos del ambiente. Cuando la temperatura ambiente se aproxima a la temperatura corporal, las respuestas fisiológicas al estrés térmico incluyen hipertermia, así como un aumento en el enfriamiento por evaporación pulmo-cutánea. Conductualmente las aves responden al estrés calórico con la reducción de los patrones de actividad durante la parte mas calurosa del día, y seleccionando micro-sitios sombrados y más frescos. Frente al fenómeno de calentamiento global, estas características respuestas conductuales presentan problemas potenciales. Si las aves deben forrajear durante las horas más cálidas del día, la elevada pérdida de agua evaporativa podría significar episodios directos de mortalidad en estas regiones. Se presenta un modelo simple que integra fisiología y conducta para predecir tiempos de sobrevivencia basados en tolerancia a la deshidratación, selección de micrositios y temperatura ambiente Date A point or period of time associated with an event in the lifecycle of the resource 2000 Subject The topic of the resource Birds, Evaporative Water Loss, aves, avian distribution, balance hídrico, calentamiento global, desiertos cálidos, distribución de aves, global warming, hot deserts, pérdida de agua evaporativa, water balance Source A related resource from which the described resource is derived Revista Chilena de Historia Natural Publisher An entity responsible for making the resource available BMC Coverage The spatial or temporal topic of the resource, the spatial applicability of the resource, or the jurisdiction under which the resource is relevant Botany, Zoology Relation A related resource <a href="http://www.scielo.cl/scielo.php?script=sci_arttext&amp;pid=S0716-078X2000000300003" target="_blank" rel="noreferrer noopener">http://www.scielo.cl/scielo.php?script=sci_arttext&amp;pid=S0716-078X2000000300003</a> http://socictopen.socict.org/files/original/ea07a78fa48ee606652aeab60392475b.pdf 3a4012a348039dab47160cb82588c01a Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

Title A name given to the resource Sistemas de producción de Spondias purpurea (Anacardiaceae) en el centro-occidente de México Creator An entity primarily responsible for making the resource Blanca C Ramírez Hernández, Pimienta Barrios Eulogio, Javier Z Castellanos Ramos, Alejandro Muñoz Urias, Guadalupe Palomino Hasbach, Enrique Pimienta Barrios Description An account of the resource Describimos las características de los agroecosistemas y rasgos morfológicos, físicos y químicos relacionados con la calidad de los frutos de la guayaba, Spondias purpurea L., que se producen en poblaciones silvestres y cultivadas en el centro-occidente de México. Spondias purpurea se desarrolla en suelos rocosos, poco profundos e infértiles, poco aptos para la agricultura tradicional. En los frutos se registró el peso, longitud axial y radial, pH, sólidos solubles totales (SST), azúcares reductores, proteínas y contenido de minerales. El peso promedio de frutos en las variedades cultivadas (20 g) resultó superior al de las silvestres (16 g). Las variedades cultivadas registraron en promedio los valores más altos de pH, SST, azúcares reductores y contenido de proteínas (3.3, 12.15º Brix, 0.38 g/100 g y 1.18 g/100 g, respectivamente) que las silvestres (3.0, 8.31º Brix, 0.24 g/100 g y 0.14 g/100 g, respectivamente). La productividad de la especie es aceptable (de 0.15 ton ha-1 a 5.0 ton ha-1) dado que requiere de un mínimo de manejo agronómico. Esta especie tiene un contenido nutrimental comparable al de las especies frutales más importantes; además, produce frutos frescos durante los meses secos de la primavera por lo que S. purpurea es fuente de agua y alimento para la fauna silvestre y doméstica. Estas características resaltan su importancia agronómica y ecológica para los ambientes tropicales y subtropicales en donde puede ser utilizada en programas de reforestación por su capacidad para desarrollarse en suelos rocosos infértiles, y en agroecosistemas en los que se practica agricultura de subsistencia. De hecho, el cultivo de S. purpurea puede ayudar a convertir suelos marginales en productivos.Production systems of Spondias purpurea (Anacardiaceae) in Central West México. Morphological, physical and chemical traits related with fruit quality characteristics of Spondias purpurea L. agroecosystems were studied in Central-West Mexico for wild and cultivated populations. Spondias purpurea regularly thrive in shallow, rocky infertile soils unsuitable for conventional crops. The weight, axial and radial length, pH, total soluble solids (SST), reducing sugars, proteins and mineral content in fruits were recorded. The mean fresh fruit weight was superior in the cultivated varieties (20 g) than in the wild (16 g). Similarly the highest values of pH, SST, reducing sugars and protein content (3.3, 12.15º Brix, 0.38 g/100 g and 1.18 g/100 g, respectively) were observed in the cultivated plantations compared with wild populations (3.0, 8.31º Brix, 0.24 g/100 g and 0.14 g/100 g, respectively). In cultivated plantations, productivity ranged from 0.15 ton ha-1 to 5.0 ton ha-1, and must be considered satisfactory, considering the low inputs of fertilizers and pesticides applied to orchards. The fruits of S. purpurea are similar in nutrimental content to more important commercial fruit species; it produces fresh fruits during the dry months of spring, when few fresh fruits are available in the local markets. In addition, S. purpurea is a source of water and food for domestic animals and wild fauna. These traits emphasize their agronomical and ecological importance for tropical and subtropical environments, where it can also be used in reforestation programs because it can grow in infertile rocky soils, and in agroecosystems inhabited by low income farmers that practice subsistence agriculture. In fact, the cultivation of Spondias has helped convert marginal lands into productive lands. Rev. Biol. Trop. 56 (2): 675-687. Epub 2008 June 30.
