Near infrared reflectance spectroscopy is routinely used for the analysis of quality components of feedstuffs. Near infrared spectrophotometers, coupled with a fiber optic probe, could enable direct measurements of the live animal. This study was conducted to characterize changes in the vulva and vestibule during the bovine estrous cycle using near infrared (NI) spectroscopy. Sixteen cycling Holstein cows were observed for estrus twice daily from 40 days postpartum for three estrous cycles or until conception was verified. In addition, weekly rectal palpations, cowside milk progesterone tests, and tailhead chalk were used to aid in estrous detection. Near infrared spectra of both the vulva and the vestibule were collected daily (Model 6500 with 1.83 m fiber optic probe, NIR Systems Inc., 1100 to 2500 nm). Twenty-four estrous periods were confirmed. Vulvar and vestibular spectra of estrous and nonestrous cows were compared. Spectral differences occurred in three regions at 1700 nm, 1790 nm, and 1800 nm (P<.05). These regions are possibly associated with changes in carbohydrate, protein, and water content. Results indicate that direct NI analysis of the live cow is possible and changes in the vulvular and vestibular tissue during the estrous cycle can be detected. However, accurate estrous detection using NI interactance is not practical at the present time because of individual cow variability.

The utilization of composed caged-layer waste (CCLW) in diets for pregnant ewes fed cereal straw was evaluated. Five sheep were assigned to five diets containing, 0, 5.72, 11.37, 23.80, and 32.69% CCLW in a 5x5 Latin square design. Water intake, feed intake and feces output were measured. Feed and feces were analyzed for dry matter, crude protein, acid detergent fiber (ADF), neutral detergent fiber (NDF), organic matter, hemicellulose and minerals. Thus, nutrient digestibility and nitrogen balance could be calculated. Forty dry, pregnant ewes in the last third of generation were assigned to four dietary treatments contained 0, 11.25, 22.08 and 31.26% CCLW in a complete randomized design. The response measured were ewe weight change, lamb birth weight and wool growth. A ewe surgically fitted with a ruminal cannula was assisted to each treatment. These ewes were adapted to diets for a 7-day period and then ruminal sumples were collected at 0, 3, 9 and 12 hours post-feeding. Connulated ewes were rotated through each treatment pen in a 4x4 Latin square design. Collected samples were analyzed for ph, volatile fatty acids, ammonia and total protozoa. Dry matter and organic matter apparent digestibility decreased as the level of CCLW increased (P<0.08). Other measurements (crude protein, NDF, ADF, hemicellulose and total ash apparent digestibility and nitrogen balance) did not differ between treatments (P<0.05). A biological trend indicated an improvement in structural carbohydrate digestibility as the level of CCLW increased. Ruminal propionic acid concentrations increased as the level of CCLW increased. Ruminal propionic acid concentrations increased as the level of CCLW increased (P<0.05). Ruminal ph and ammonia concentration tended to increase as the level of CCLW increased. These measurements indicated a better ruminal environment for fiber hydrolysis. Daily body weight gain, lamb birth weight and wool growth of ewes did not differ between treatments (P<0.05). The results show that CCLW is a satisfactory source of supplemental nitrogen for gestating ewes.

Using three separate and unique sources of data, this study was designed to address: a) the associations between pregnancy-related violence and femicide with sociodemographic characteristics of victims and offenders and with family dynamics, b) how pregnancy affects the risk for threats of violence, power and control tactics, physical violence, stalking, sexual violence, and femicide, and c) how pregnancy contributes to increased severity of abuse. The overall results reveal a significant statistical correlation between pregnancy and the increased risk of intimate partner abuse on many dimensions, including physical abuse, stalking and harassment, sexual abuse, threats of serious harm and death, lethality risk, and power and control. The correlation between pregnancy and femicide is less clear and in need of further examination. While the nature of pregnancy as a risk factor across multiple dimensions of abuse is certainly pervasive, the findings indicate that power and coercive control warrants close attention as a potentially prominent and dangerous dynamic. Women of younger age, those single or divorced, residing with an IP, and having children in the home were shown to have a significantly increased risk of non-lethal and lethal IPV in all three samples. The findings contribute evidence to existing literature concerning potentially catastrophic outcomes for pregnancies occurring in an abusive context, including extremely high rates of miscarriage in abusive relationships. Implications for practice and for research are discussed.

The purpose of the study was to research leadership during uncertainty to identify managerial implications on organizational performance and enhance the limited body of academic literature available on the topic currently. The implications regarding leadership are not limited to the COVID-19 pandemic but instead widely applicable to leadership during uncertainty overall. The pandemic simply provided an example of uncertainty, which was the context. Additionally, as mining is a global industry with widespread follow-on effects on global economies - authors believe that the results from this research are not limited to the mining industry itself and instead widely applicable to senior-level managers in multinational organizations worldwide. The methodology implemented ensures that leaders at any level can extract practical guidance from this research to determine how they may act during times of uncertainty and potential flow-on effects of their chosen leadership style.  Organizations can remain relevant, achieve long-term success and maintain the expected level of performance through uncertainty by adopting a transformational model of leadership that addresses the needs of a fluctuating environment. Uncertainty is the shortage of knowledge and information about probabilities of the future state of events. Organizational leaders need to provide the necessary guidance, inspiration, and motivation to the members because their approach influences the organizational performance. Essentially, people look up to their leaders during uncertain times. The research results showed that transformational managers could offer idealized influence, inspirational motivation, intellectual stimulation, and individualized consideration to team members during uncertainty. These outcomes were achieved through encouraging two-way communication, providing necessary guidance and inspiration to bring out and encourage new idea generation and critical thinking.  Results of the research further showed that transformational leadership has positive effects on organizational performance. Teams functioned properly without much supervision, members remained motivated, the workforce interacted more efficiently, and creative ideas came out when leaders and managers practiced a transformational leadership style. Organizational performance increased through meeting deadlines, maintaining the flow of work, KPIs, production, and non-financial metrics such as culture and safety considerations.

Third-generation advanced high-strength steels (3G AHSS) are being developed to assist in vehicle light weighting so that fuel efficiency may be improved without sacrificing passenger safety. 3G-AHSS have received significant interest from the automotive industry as a critical candidate for their unique combination of high strength and ductility. However, due to selective oxidation of the principal alloying elements such as Mn, Si, Al, and Cr at the steel surface during the annealing stage prior to immersion in the galvanizing Zn(Al, Fe) bath, the process of continuous hot-dip galvanizing of these steel is challenging. This thesis determined the influence of annealing process parameters such as oxygen partial pressure and annealing time, on the selective oxidation and reactive wetting of an Fe-0.15C-5.56Mn-1.17Si-1Al (wt%) prototype 3G AHSS during intercritical annealing as well as continuous galvanizing. Simulated annealing and galvanizing were conducted on the prototype Fe-0.15C-5.56Mn-0117Si-1Al (wt%) 3G steel; Intercritical annealing heat treatments were carried out at 690˚C in a N2-5 vol pct H2 process atmosphere under dew points of 223 K (–50 °C), 243 (–30 °C) and 268 K (–5 °C). MnO was the major oxide formed at the outmost layer of the external oxides on all annealed samples. The experimental parameters, on the other hand, had a substantial impact on the morphology, distribution, thickness, and surface oxide coverage. The greatest Mn surface concentration as well as maximum surface oxide coverage and thickness was obtained by annealing the panels under the 223 K (–50 °C) and 243 (–30 °C) dp process atmospheres. The oxides formed under these process atmospheres largely comprised coarse, compact, and continuous film nodules. In contrast, MnO nodules formed under the 268 K (–5 °C) dewpoint process, exhibited wider spacing between finer and thinner nodules, which was consistent with the internal oxidation mode, while under 223 K (–50 °C) dp process atmosphere, generally external oxidation took place. Poor reactive wetting was obtained for the panels annealed under the 223 K (–50 °C) dp process atmosphere for both the 60 s and 120 s holding times as well as the 243 K (–30 °C) dp process atmosphere for 120 s. This was attributed to the formation of a thick, compact oxide layer on the steel surface, which acted as a barrier between the substrate and Zn bath, preventing Fe dissolution from the substrate surface for the formation of the desired Fe2Al5Znx interfacial layer. However, a well-developed interfacial Fe-Al intermetallic layer was formed under the 268 K (–5 °C) and 243 (–30 °C) dp process atmospheres for intercritical annealing times of 60 s, which is indicative of a good reactive wetting since the thinner and nodule-like oxides on the steel surface after annealing encourage the reactive wetting. External oxides morphology plays a dominant role in facilitating the contact between Zn-alloy bath and the substrate via different mechanisms such as aluminothermic reduction which occurred for the sample annealed under the 268 K (–5 °C) dp process atmosphere. / Thesis / Master of Applied Science (MASc)

The main purpose of the study is to investigate if Boverkets supplement BEN is reasonable for apartment buildings with individual metering and charging for hot water. But also if there is any connection between hot water consumption, number of residents, bathtub and number of rooms in the apartments. Finally, it is investigated whether the residents make any active choice to reduce their consumption of hot water and if so why.In total, measurement data has been obtained from 2097 apartments distributed among 21 tenant-owned associations in Stockholm and Uppsala where Riksbyggen is the estate manager. The study also includes a comprehensive survey that was sent out to 975 apartments distributed among nine tenant-owned associations. The purpose of the survey is to get a better picture of how households reason about their hot water consumption. Through the database provided by Infometric, the work has had access to the apartments' actual hot water consumption. Thus, it has been possible to retrieve measurement data from all associations and to pair individual survey responses with the apartments' unique meter ID.The results presented in the study show that the associations are 27.1% below Boverkets supplement BEN for ordinary fixtures. At BEN for low-flush fixtures, the associations are 19.6% below the supplement. The study shows that factors such as the number of residents and the number of rooms and kitchens have a major impact on hot water consumption. Indications also show that bathtubs affect consumption to the negative to the extent that hot water consumption tends to increase. It also appears that residents are actively trying to minimize their hot water consumption where environmental reasons are stated as the main cause.

In this study I present a new understanding of Vietnamese existentialism during the period 1954-1975, the period between the Geneva Accords and the fall of Saigon in 1975. The prevailing view within Vietnam sees Vietnamese existentialism during this period as a morally bankrupt philosophy that is a mere imitation of European versions of existentialism. I argue to the contrary that while Vietnamese existential philosophy and European existentialism share some themes, Vietnamese existentialism during this period is rooted in the particularities of Vietnamese traditional culture and social structures and in the lived experience of Vietnamese people over Vietnam's 1000-year history of occupation and oppression by foreign forces. I also argue that Vietnamese existentialism is a profoundly moral philosophy, committed to justice in the social and political spheres. Heavily influenced by Vietnamese Buddhism, Vietnamese existential philosophy, I argue, places emphasis on the concept of a non-substantial, relational, and social self and a harmonious and constitutive relation between the self and other. The Vietnamese philosophers argue that oppressions of the mind must be liberated and that social structures that result in violence must be changed. Consistent with these ends Vietnamese existentialism proposes a multi-perspective ontology, a dialectical view of human thought, and a method of meditation that releases the mind to be able to understand both the nature of reality as it is and the means to live a moral, politically engaged life. This study incorporates Vietnamese existential philosophy from 1954-1975 into the flow of the Vietnamese philosophical tradition while also acknowledging its relevance to contemporary Vietnam. In particular, this interpretation of Vietnamese existentialism helps us to understand the philosophical basis of movements in Vietnam to bring about social revolution, to destroy forms of social violence, to reduce poverty, and to foster equality, freedom, and democracy for every member of society. By offering a comparison between Vietnamese existential thinkers and Western existentialists, the study bridges Vietnamese and the western traditions while respecting their diversity. In these ways I hope to show that Vietnamese existentialism makes an original contribution to philosophical thought and must be placed on the map of world philosophies. / Philosophy

The Portevin-le Chatelier effect in a copper-3.2 at.% tin alloy has been used to investigate the rate of vacancy production during reversed plastic flow. The production rate per unit strain has been shown to be approximately half the value found for straight tensile deformation. It was inferred from this that fatigue is not a highly efficient method for producing vacancies. The relationship between the dislocation density and the tensile plastic strain for this alloy has been determined by transmission electron microscopy. It was found to obey the law, p = const. E^1.17±0.13. It was also found that during reversed plastic flow this law was no longer valid. / Thesis / Master of Science (MSc)

Typological distributions are the combined result of universal structural principles, areal diffusion, and shared descent. The core concern of quantitative typology is to disentangle and to identify these various factors.While areal and structural factors can be tested against each other in standard multivariate designs based on sample stratification, genealogical factors cannot be handled by sample stratification since about one third of all proven families (the strata needed) are isolates, i.e. count only one member. In response, typologists have since long sought to control for genealogical relations during sampling rather than during statistical testing. But available methods suffer from a number of drawbacks. Most importantly, they are not sensitive to the fact that different typological variable have different degrees of stability (genealogical dependence) within families, and that this again varies from family to family.This article proposes a refined method for genealogical control during sampling, which is based on DRYER’s (1989) proposals but is sensitive to actual distributions within genealogical units at each taxonomic level.

Heightened perceptions of threat, along with the proximity and nature of terrorist attacks, can influence trust dynamics. This dynamic often increases due to heightened social cohesion and collective resilience. This study examines the influence of jihadist terrorist attacks on social trust within communities in the Netherlands, Sweden, France, and Germany. The study hypothesized and theorized about how jihadist terrorism influences shifts in societal trust among the affected populations. Utilizing a "multiple unexpected events during survey" (MUESD) research design and integrating individual-level responses from the European Social Survey (ESS) with event-specific data from the Global Terrorism Database (GTD). The findings indicate a statistically significant increase in social trust shortly after the attacks, within the first to two weeks. This emphasizes the link between external security threats and internal social cohesion. By providing a nuanced understanding of the resilience responses activated during crises, the study contributes to the knowledge of the socio-political impact of terrorism and offers insights into the shifts in societal trust among affected populations. This research underscores the importance of understanding how societies react to and recover from terrorist threats, shedding light on the dynamics of trust and community solidarity in the face of adversity.
