Visiting Friends and Relatives (VFRs) travelers and imported malaria in the Palermo district (Sicily).
2014
Abstract Introduction. Although Italy has been malaria-free since 1970, the infection is commonly introduced into the country by travelers and immigrants from endemic areas. The term VFRs refers to immigrants from malaria-endemic countries who are regularly resident in a malaria-free area, and who travel to their countries of origin to visit friends and relatives (VFRs). This group is at special risk of malaria as they are unaware of having lost their transitory immunity to the disease. Methods. We conducted a retrospective study at the International Travelers Department of Palermo (Italy), examining records of malaria cases (67) reported over the period from 1998 to 2013. Results. VFRs rep…
How Universal Is the Relationship between Remotely Sensed Vegetation Indices and Crop Leaf Area Index? A Global Assessment
2016
This study aims to assess the relationship between Leaf Area Index (LAI) and remotely sensed Vegetation Indices (VIs) for major crops, based on a globally explicit dataset of in situ LAI measurements over a significant set of locations. We used a total of 1394 LAI measurements from 29 sites spanning 4 continents and covering 15 crop types with corresponding Landsat satellite images. Best-fit functions for the LAI-VI relationships were generated and assessed in terms of crop type, vegetation index, level of radiometric/atmospheric processing, method of LAI measurement, as well as the time difference between LAI measurements and satellite overpass. These global LAI-VI relationships were evalu…
Biežākās arodsaslimšanas un to iemesli māsām dažādās vecuma grupās lokālajā slimnīcā
2020
Bakalaura darba tēma – “ Biežākās arodsaslimšanas un to iemesli māsām dažādās vecuma grupās lokālajā slimnīcā”. Izvēlētās tēmas aktualitāti nosaka tas, ka katru gadu cilvēku skaits ar pirmreizējām arodsaslimšanām pieaug. Pēc Valsts darba inspekcijas 2018. gada datiem, veselības aprūpes nozare ir trešā lielākā nozare, kurā ir konstatēts viens no lielākajiem jauno arodslimnieku skaits, turklāt 66% no pirmreizēji apstiprinātajiem arodslimniekiem bija sievietes. Darba mērķis ir izpētīt un analizēt kādas ir biežākās arodsaslimšanas un to iemesli māsām dažādās vecuma grupās. Pētniecības uzdevumi ir izpētīt un analizēt literatūru par arodsaslimšanām, arodsaslimšanām māsu vidū, arodsaslimšanu izrai…

Carbon Stocks in Peri-Urban Areas: A Case Study of Remote Sensing Capabilities
2014
Peri-urban areas are the extension of cities into contiguous areas, where households and farms coexist. Carbon stocks (CSs) assessment, a concept here extended to urban features, has not yet been studied in depth over peri-urban areas due to uncertainties in such CSs quantification, level of detail required about construction materials, and the high spatial variability of those stocks. Remote sensing (RS)-based techniques have been successfully utilized in urban areas for assessing phenomena such as soil sealing, sprawl patterns, and dynamics of surface imperviousness, especially focusing on land cover classification at high to medium spatial scales. Over the floodplain study area of Emilia…

Cálculo de la evapotranspiración real diaria en la zona norte de Finlandia empleando técnicas de teledetección
2005
J. M. Sánchez Tomás (Juan.M.Sanchez@uv.es) Hasta hace poco tiempo el estudio de la evapotranspiración (LE), fundamental en la ecuación de balance de energía, excluía zonas forestales debido a las dificultades experimentales de la toma de medidas en estas regiones. La teledetección acabó con dichas dificultades, facilitando el estudio de la LE real dentro de estas zonas, que suponen en torno a un 30% de toda la superficie terrestre. En este trabajo se presenta un método operativo para determinar la LE real a partir de medidas de temperatura de la superficie realizadas desde satélite. Este estudio se llevó a cabo de abril a junio de 2002 en Sodankylä, una región de bosque boreal en el norte d…
Fire severity estimation in southern of the Buenos Aires province, Argentina, using Sentinel-2 and its comparison with Landsat-8
2018
[EN] Assessment of rural fire severity is fundamental to evaluate fire damages and to analyze recovery processes in a low-cost and efficient way. Burnt areas covering shrubs and grasslands were estimated in more than 30,000 km2 in Argentina from December 2016 to January 2017. The study area presented in this work is located in the South of the Buenos Aires province, and it covers a semiarid area with the presence of xerophilous shrubs and grasslands. This is one of the most abundant ecosystem in Central and Southern Argentina. Field campaigns were carried out over the area affected by the fire in order to georreference the burnt plots and characterized the fire severity in 5 levels. The obj…
Rationale and evidence on the use of tocilizumab in COVID-19: a systematic review
2020
Abstract Background Tocilizumab is an IL-6 receptor-blocking agent proposed for the treatment of severe COVID-19. The aim of this systematic review was to describe the rationale for the use of tocilizumab for the treatment of COVID-19 and to summarize the available evidence regarding its efficacy and safety. Methods MEDLINE, PubMed, EMBASE, pre-print repositories (bioRxiv and medRxiv) and two trial Registries were searched for studies on the use of tocilizumab in COVID-19 or SARS-CoV-2 infection, viral pneumonia, and/or sepsis until 20th June 2020. Results We identified 3 indirect pre-clinical studies and 28 clinical studies including 5776 patients with COVID-19 (13 with a comparison group,…
