This diploma thesis deals with chemical analysis of selected frozen, dried and lyophilized fruit, specifically Mirabelle de Nancy, Aronia Nero and blackcurrant varieties Gairn Ben and Ben Lomond. In the theoretical part taxonomy and botanical characteristics of selected fruit are given. Subsequently the utilization of fruit in food industry is described. In common the theoretical part focuses on lyophilisation and drying of fruit and raw food. Further in this part the methods of phenolic substances, anthocyanins, antioxidant capacity and finally ascorbic acid and carbohydrates value measurements are specified. In the experimental part the value were determined measurements of biologically active substances: total phenols, total anthocyanins, antioxidant capacity, ascorbic acid and carbohydrates. For all value measurements were compared the frozen, dried and lyophilised samples of every single fruit. Further, the every sort of fruit were compared to each other. Following the raw food preparaon a product of lyophilised fruit was made.

This thesis deals with the study of soils freezing in terms of phase change of water contained in the soil strata on green roofs. The aim of this work is to verify the effect of phase transformation of water on the course of temperature oscillation. First described the basic characteristics of soils generally, and subsequently described processes occurring during phase transformation of water in the soil and has been carried out experimental verification of the effect of moisture in the soil on the course of temperature oscillation. In the overall evaluation of the work, an analysis of the effect of phase change water in soil on the course of temperature oscillation and the resulting conclusion of work.

<p>In recent years conservation of minor livestock breeds has been faced with numerous challenges attributed to decreasing national herd sizes, as well as differences in reproduction and growth. One such minor swine breed, the Large Black pig (LB), is increasingly attractive to small farmers due to their foraging abilities and carcass characteristics. Therefore, the LB pigs have been used in niche pork production systems which market pasture-raised pork products. The LB breed is critically endangered, maintaining a registered breeding population of less than 400 animals, with increasing prevalence of inbreeding and genetic drift. Therefore, the LB breed could benefit from a genetic importation to increase genetic diversity in a national herd with rapidly decreasing animal numbers. A genetic importation would require frozen semen to be brought in from another country for use in breeding U.S. pigs. Frozen-thawed semen (FTS) presents challenges for swine due to the reduced motile sperm cells which negatively impacts fertility. Therefore, the present study evaluated the utilization of FTS in a genetic importation for the LB pig. </p><p>A genetic importation occurred in 2016 where semen from the United Kingdom was used on various farms in the U.S. but resulted in zero piglets born. Therefore, 16 LB sows were donated to Purdue University for research into improving estrous and ovulation synchronization to facilitate FTS utilization. Four breeding replicates were performed where following 14 days of Matrix feeding, OvuGel® was administered at 144 h following last Matrix feeding (LMF) or 96 h in post-weaned sows and two FTS inseminations occurring at: 30 and 36 h, 17 and 23 h, 24 and 30 h, and 24 and 32 h after OvuGel® for replicates 1-4, respectively. Approximately 2.64±0.3 billion motile sperm cells per insemination were utilized in replicates 1-3 with American LB FTS, with replicate 4 utilizing 0.34±0.03 billion motile sperm cells of imported FTS. Follicle diameter (<i>P</i>=0.260), ovulation within 48 h of OvuGel® (<i>P</i>=0.411), and weight prior to breeding (<i>P</i>=0.681) did not influence conception rate, however expression of estrus was determined to significantly influence conception rate (<i>P</i>=0.043). Seventy-five LB piglets were weaned across the first three breeding replicates, with parity 2 sows observed to have larger litter sizes than parity 1 sows (<i>P</i>=0.066).</p> <p>Large Black and Duroc-sired (DS) crossbred pigs from replicates 1 and 2 farrowing were fed corn and soybean meal based finishing diets supplemented with (FIB) or without alfalfa and wheat middlings (CON). Following 6 dietary phases through finishing, 25 LB and 25 DS pigs were slaughtered at similar ages for digestive organ dissection and carcass measurements. Loin muscles were evaluated for fresh pork quality and instrumental color and tenderness. LB pigs had a reduced ADG (<i>P</i><0.0001) and G:F (<i>P</i><0.0001) compared to DS pigs. Pigs fed FIB resulted in reduced ADG (<i>P</i>=0.020) and reduced G:F (<i>P</i>=0.007). At slaughter LB pigs were 26.4 kg lighter than DS pigs (<i>P</i><0.0001), and pigs that were fed FIB had lighter live weights (<i>P</i>=0.002) than pigs fed CON. LB pigs had 28.5±1.3 cm² smaller longissimus muscle area (<i>P</i><0.0001), yielding 2.0 cm more 10^th rib back fat than DS pigs (<i>P</i><0.0001). CON pigs had heavier HCW (<i>P</i><0.0001) than FIB pigs, however FIB pigs had greater percent lean (<i>P</i>=0.015). LB pigs had significantly reduced percent lean than DS pigs (<i>P</i><0.0001). LB pigs had loins with reduced drip loss (<i>P</i>=0.009) and cooked shear force values (<i>P</i><0.0001). Overall, the growth and carcass composition of the pigs was most affected by genotype, and to a lesser extent than the type of diet fed. </p> <p>In conclusion, the genetic importation of LB semen was successful as ½ blood piglets were created for dispersal into the U.S. LB herd. Improvements in FTS utilization in this heritage breed contributed to the successful creation of live-born pigs. Additionally, growth and carcass information was obtained for LB breeders to use in understanding and marketing of this heritage breed of pigs.</p>

After the fall of the Soviet Union a number of violent ethnic disputes were concluded through the establishment of ceasefires but have yet to be finalized through peace accords. This development resulted in the creation of de facto states in a setting known as ‘frozen conflicts’. These de facto states have managed to endure decades of unrecognition, stuck in a situation of “no war, no peace” and constitutes today “effective” political entities. The post-war development in these frozen conflicts has continuously surprised academia, defying pessimistic prediction of their sustainability. Following the positive, hybridized peace etymology laid out by Oliver Richmond, this thesis aims at exploring the peace- and state processes that has occurred during the Nagorno Karabakh peace process in order to explain the ambiguous developments that have been going on despite the limbo-like state of unrecognition. The relation between external and internal processes is interrogated through a periodization of key events, and thereafter a comprehensive analysis of how the processes relate to each other over time. The thesis concludes that the strong presence of identity politics regarding the historical Nagorno Karabakh favors the often violent and protective state formation process but is at least partially controlled by the international attempts at peace building. Local formations of peace do not allow for a reintegration of Nagorno Karabakh into Azerbaijan, at least not without explicit and extensive security and autonomy guarantees. Likewise, the external processes of peace and state building does not allow for local agency from Nagorno Karabakh, as it is viewed through a negative ontology of peace. The processes does provide some rather successful developments, as the almost finalized Land swap deal and the Madrid principles, but lacks the momentum of conquering the dominance of perceived or actualized violent state formation processes.

A scarcity of experimental studies covering the decomposition of dismembered body parts has created a gap in knowledge of the effect of dismemberment on the estimation of post-mortem interval (PMI) and their post-mortem history in a forensic context. The aim of this study was to record the decay of detached body parts in some depositional settings where they are likely to be disposed of: burial, wrapping and freezing. A series of controlled laboratory experiments was carried out using Sus scrofa body parts and pork belly, to understand how ambient temperature, soil moisture, and wrapping and freezing of body parts affected their decomposition. Rates of decay were subject to a higher temperature and soil moisture level in a burial microenvironment, with metabolic microbial activity confirming the results. Temperature was a predominant factor in the decay rates of wrapped body parts, with a raised ambient temperature causing even higher temperature in the wrapped microenvironment, resulting in accelerated decay rates. Freezing decelerated the decomposition of body parts, retarding microbial growth and activity and causing differential decomposition between body parts. Freezing demonstrated morphological changes in body parts specific to this microenvironment. Predominantly Gram-negative bacteria that may be associated with body microflora were involved in decomposition in all three microenvironments. Taphonomic, chemical and microbiological analyses carried out in this study have a potential for forensic application in the examination of dismembered remains that have been deposited in freezing and indoor settings. Further experiments are necessary to understand buried decomposition patterns in field conditions.

In this thesis, I analyze the Minions from Universal Pictures' Despicable Me franchise (2010-2020), Olaf from Disney's Frozen franchise (2013-2019), and Ducky and Bunny from Pixar's Toy Story 4 (2019). Although these characters are not intended to represent human beings but are fictional nonhuman species, examining them through the lens of racialization defamiliarizes them and reveals how children's media not only perpetuates specific caricatures of people of color but subtly naturalizes what race is as an assemblage of visual, verbal, performative, and affective components. While scholars studying racial representations in children's animated films often focus on how animated characters speak in non-white dialects, engage in stereotypes, and reproduce visual aspects of race, this interpretive framework does not address the ways in which race goes beyond the surface, nor does it address complex interactions between race, gender, and sexuality. Rather than asserting that nonhuman animated characters are certain races, my term "submerged racialization" suggests that animated characters are not direct representations of "real" non-white bodies but are aggregates of what it is to be racialized in historically specific ways that are co-constitutive with gender and sexuality. These features dwell beneath the surface like a skeleton, overdetermining how the characters perform without necessarily influencing their outward appearance in easily recognizable ways. In the first chapter, I analyze how the Minions enact a multi-layered submerged racialization as Black, Asian American, and indigenous beings. The second chapter discusses how Olaf's racialization shifts across different objects in the Frozen franchise, addressing his relationship to Blackness and Hawaiianness in the first film, the featurette, "pull apart" plush toys, and Hula Olaf figures. Finally, in my third chapter, I show how Ducky and Bunny fulfil roles as Black comedic sidekicks and demonstrate how Black men have been constructed as aggressive, hypersexual threats. By uncovering the submerged racialization underlying today's most popular children's franchises, I stress that race is reproduced and reinvented in the seemingly innocent intimate spaces around us. / Master of Arts / What race are the Minions? While this may seem a strange question, scholars of children's animated films have often described the race of nonhuman animated characters based on whether they speak in non-white dialects, engage in stereotypes, and reproduce certain visual characteristics, such as black skin. However, I argue that the Minions from Universal Pictures' Despicable Me franchise (2010-2020), Olaf from Disney's Frozen franchise (2013-2019), and Ducky and Bunny from Pixar's Toy Story 4 (2019) are "submerged racialized figures" and not direct representations of "real" non-white bodies. These characters demonstrate what it means to be racialized in historically specific ways that intersect with their gender and sexuality. Their racial features dwell beneath the surface like a skeleton, affecting their representation without necessarily influencing their outward appearance in easily recognizable ways. In the first chapter, I analyze how the Minions demonstrate a multi-layered submerged racialization throughout the franchise as Black, Asian American, and indigenous beings. The second chapter discusses how Olaf's racialization shifts across different objects in the Frozen franchise, changing his relationship to Blackness and Hawaiianness in the first film, the featurette, "pull apart" plush toys, and Hula Olaf figures. Finally, in my third chapter, I show how Ducky and Bunny fulfil roles as Black comedic sidekicks and demonstrate how Black men have been constructed as aggressive, hypersexual threats. By uncovering the submerged racialization within today's most popular children's franchises, I demonstrate how race is reproduced and reinvented in the seemingly innocent intimate spaces around us.
