Abstract:

Introduction: Cryopreservation of human sperm is considered a routine practice in assisted reproduction laboratories. Semen samples are mainly cryopreserved as a back-up for procedures, donor sperm, and validation of samples from human immunodeficiency virus-positive patients. Human immunodeficiency virus semen samples generally result in a low yield of purified spermatozoa after decontamination. These samples need to be cryopreserved for later use. Unlike conventional cryopreservation, vitrification does not use harmful cryoprotectants, thereby potentially reducing sperm damage. Vitrification

Abstract:

Digital Preservation addresses a significant threat to our cultural and economic foundation: the loss of access to valuable and, sometimes, unique information that is captured in digital form through obsolescence, deterioration or loss of information of how to access the contents. Digital Preservation has been defined as “The series of managed activities necessary to ensure continued access to digital materials for as long as necessary” (Jones, Beagrie, 2001/2008). This thesis develops a conceptual model of the core concepts and constraints that appear in digital preservation - DePICT (Digital

Abstract:

The seafood industry is of considerable importance to both the New Zealand and global economies and therefore tissue preservation technologies that increase product quality and/or prolong shelf life have the potential to add significant value. Technologies for maintaining the viability of isolated tissues also have a wide range of other medical and industrial applications. This thesis examines the relationship between metabolic function, oxidation and cell death and the resulting stability of the non-viable tissues during long term storage in chinook salmon (Oncorhynchus tshawytscha) red and w

Abstract:

La question « SDF » est étudiée au sein de deux paradigmes : l’approche critique qui insiste sur les phénomènes de domination sociale et l’approche interactionniste qui souligne les adaptations successives que les individus mettent en oeuvre. Ces adaptations sont étudiées à travers des situations particulières dans lesquelles l’identité de sansdomicilese construit et une carrière se dessine. Cette carrière est abordée soit comme une carrière de désocialisation dont la clochardisation constitue l’horizon, soit comme une carrière de survie dont le maintien de soi forme la perspective quotidienne

Abstract:

Edible flowers have been used in food since ancient times. Currently, their consumption has increased in less traditional countries in what regards this practice, as a result of the growth and development of gastronomic market and by the gourmet chefs, who begin to use edible flowers in their dishes, due to their beauty and taste. However, it is a very perishable product, whose quality and safety need to be guaranteed. In this order, the main objective of the present work was to test several post-harvest technologies (separately and combined) to different edible flowers species, accordi

Several successes have been recorded in the field of action recognition but only very few has focused on dance. This is because dance actions and, especially Traditional African dance, are long and involve fast movement of body parts. This research proposes a novel framework that applies data science algorithms to the field of cultural preservation by applying various deep learning techniques to identify, classify and model Traditional African dances from videos.

Abstract:

<p>Modeling microbial inactivation has a great influence on the optimization, control and design of food processes. In the area of food safety, modeling is a valuable tool for characterizing survival curves and for supporting food safety decisions. The modeling of microbial behavior is based on the premise that the response of the microbial population to the environment factors is reproducible. And that from the past, it is possible to predict how these microorganisms would respond in other similar environments. Thus, the use of mathematical models has become an attractive and relevant tool in
