Adventices : effets directs et indirects du réchauffement
2021
Contexte - Les conditions météorologiques extrêmes (gels, précipitations extrêmes, sécheresses automnale ou printanière) ont tendance à se multiplier, perturbant les pratiques agricoles,entraînant des pertes de rendement ou l’abandon de la culture. Les effets de la hausse des températures ou de l’allongement de l’ensoleillement sont plus marqués sur les dates de récoltepar exemple.Mais peut-on prévoir l’impact de ces changements climatiques sur les espèces adventices ?¾ effets diReCts - Les interactions entre caractéristiques climatiques, pratiques culturales et traits biologiques dechaque espèce rendent les prévisions difficiles. La hausse des températures peut avoir des effets directs sur…
Evaluation of Multispectral Data Acquired from UAV Platform in Olive Orchard
2023
Precision agriculture is a management strategy to improve resource efficiency, production, quality, profitability and sustainability of the crops. In recent years, olive tree management is increasingly focused on determining the correct health status of the plants in order to distribute the main resource using different technologies. In the olive grove, the focus is often on the use of multispectral information from UAVs (Unmanned Aerial Vehicle), but it is not known how important spectral and biometric information actually is for the agronomic management of the olive grove. The aim of this study was to investigate the ability of multispectral data acquired from a UAV platform to predict nu…
Estudio funcional y ecográfico con tecnología hd Live y efecto Doppler del trasplante ortotópico de tejido ovárico
2017
Existe la posibilidad, todavía en fase experimental, de preservar la función ovárica y la fertilidad a las niñas y mujeres a las que se les diagnostica un cáncer mediante la extracción de la corteza ovárica, antes del inicio del tratamiento gonadotóxico. La paciente es estudiada, se realiza la extracción de la corteza ovárica y cuando la paciente se cura, se reimplanta la corteza y de esta manera la paciente puede recuperar la capacidad funcional ovárica normal y la posibilidad de quedar embaraza de manera natural (hoy en día la técnica de elección es la preservación de ovocitos y de embriones). En esta tesis se analiza ecográficamente, con la última tecnología disponible, como funcionan es…
Estudio del umbral de disconfort a la presión en el pie de las personas mayores
2014
INTRODUCCIÓN El dolor en el pie en los mayores es uno de los principales problemas de la salud pública¹. El 41,9% de los mayores de 50 años tiene al menos una dolencia del pie². Los problemas más frecuentes de los pies se asocian con la existencia de sobrepresiones³. Los profesionales tratan de disminuirlas mediante adaptaciones⁴. Pero al no tener valores de referencia, dichas adaptaciones suelen realizarse de forma intuitiva⁵. La cuantificación de los umbrales de tolerancia a la presión en la planta del pie permitiría establecer tanto patrones de distribución como criterios de tratamiento y/o prevención del dolor. Conociendo el umbral de disconfort podremos evitar el siguiente estadío, es …
In vitro evaluation of the influence of bone cortical thickness on the primary stability of conventional- and short-sized implants
2022
Made available in DSpace on 2022-04-28T19:50:57Z (GMT). No. of bitstreams: 0 Previous issue date: 2022-01-01 Background: The aim of this in vitro study was to evaluate the influence of the cortical thickness on the primary stability of short and conventional-sized implants with two types of prosthetic connection. Material and Methods: Seventy-two implants were used. These implants were placed in polyurethane blocks that simulated low-density bone tissue (type IV bone), with two bone cortical heights (type I bone): 1mm and 3mm. The implants were divided into 6 groups with 12 implants each according to the type of prosthetic connections (external-hexagon -EH and morse taper- MT) and implant s…
Controversies in ameloblastoma management: Evaluation of decision making, based on a retrospective analysis
2020
Background The ameloblastoma management is still challenging to the high recurrence rates and significant morbidity associated with radical treatment. The purpose of this 10-year retrospective study was to analyze the influence of ameloblastoma type and treatment strategy on the long-term outcomes and recurrence rates. Material and Methods The retrospective analyses of 64 histologically-confirmed ameloblastoma cases was performed. The possible risk factors for recurrence and the development of complications were estimated statistically. Results The treatment strategy applied for this group of patients was the following: thirty-four patients (53.1%) were treated conservatively with enucleati…
Challenges Associated with Byproducts Valorization—Comparison Study of Safety Parameters of Ultrasonicated and Fermented Plant-Based Byproducts
2020
In order to promote the efficient use of byproducts from the production of plant-based beverages, which still contain a large amount of nutritional and functional compounds, microbiological and chemical safety characteristics should be evaluated and, if needed, improved. Many challenges are associated with byproducts valorization, and the most important ones, which should be taken into account at the further steps of valorization, are biological and chemical safety. For safety improving, several technological treatments (biological, physical etc.) can be used. In this study, the influence of low-frequency ultrasonication (US) and fermentation with Lactobacillus casei LUHS210 strain, as phys…
Economic Sustainability of Italian Greenhouse Cherry Tomato
2014
Greenhouse tomato cultivation plays an important role in Sicily, being the primary production area in Italy, due to its favorable pedo-climatic conditions that permit extra-seasonal productions. In Sicily, more than half of greenhouse tomato production is derived from the Province of Ragusa on the southeastern coast, where especially cherry tomato typologies are cultivated. Over the last decade, the Ragusa Province has registered a decrease both in terms of greenhouse tomato area and harvested production due to several structural problems that would require restructuring of the tomato supply chain. Thus, since recognition of real costs and profitability of tomato growing is a vital issue, b…
