Nitrogen is one of the most important part of nutrition of winter wheat. However, if in the crop are weeds capable of using nitrogen more efficiently, the area-wide fertilization can make competitive ability higher for weed, after that there is a reduction in the yield of wheat. Example of weed with this ability is cleavers (Galium aparine). Possibility how we can eleiminate this weed ability is using precision placement of fertilizer under the crop row. The aim of this thesis is finding out of positive effects of precision placement of nitrogen fertilizer (calcium nitrate) in comparison with area-wide fertilization for reduction competitive ability of cleavers against wheat. The experiment was containerized and was run in a growth room with controlled conditions. Based of the experiment, it was found, that competition of cleavers was decreased by precision placement of fertilizer but growth of wheat was decreased too because of higher nitrate availability in the soil. This method of fertilization does not produce the expected effect for better wheat competitive ability.

Health Informatics has enlightened by the recent development in the internet of medical things 4.0. Healthcare services have seen greater acceptance of Information and Communications Technology (ICT) in recent years; in light of the increasing volume of patient data, the traditional way of storing data in physical files has eventually moved to a digital alternative such as Electronic Health Record (EHR). However, the conventional healthcare data systems are plagued with a single point of failure, security issues, mutable logging, and inefficient methods to retrieve healthcare records. Solid (Social Linked Data) has been developed as a decentralized technology to alter digital data sharing and ownership for its users radically. However, Solid alone cannot address all the security issues posed to data exchange and storage. This work combines two decentralized technologies, Solid ecosystem and Blockchain technology, to tackle potential security issues using Solidity-based Smart Contracts, thereby providing a secure patient centric design. This research evaluates a model solution for secure storage, emphasizing secure auditing of accessing the data stored. The architecture will also come with algorithms that will provide developers with logical instructions to implement the artefact.

Overweight and obesity trends are on the rise, and young people are no exception. The popular phrase "Freshman 15" suggests that freshmen in college tend to gain weight faster than other populations. There is a growing body of literature that supports evidence of increased weight gain during the transition from high school to college. This study sought to examine not only weight changes among freshmen, but body composition, body mass index (BMI), and waist circumference (WC) changes as well. Body composition was measured using air displacement plethysmography (Bod Pod®). This study examined changes in both males (n = 45) and females (n = 43), as well as a subsample of Division I collegiate athletes (n = 19). The present study evaluated changes that occurred among a final group of 107 participants. Measurements were taken at the beginning of the semester in September, again in December, and at the end of the school year in April. Self-report questionnaires based on nutritional and physical activity were also evaluated. Significant increases in weight (2.1 ± 2.6 kg), BMI (0.69 ± 0.87 kg/m2), and WC (1.7 ± 2.7 cm) did occur during the freshman year. However, the change in body composition was not significant (p > 0.05). There was no relationship between the nutrition responses and the body composition changes that occurred with the exception of a weak relationship between change in "total caloric consumption during your freshman year" and change in body mass (r = 0.25, p < 0.05), change in BMI (r = 0.24, p < 0.05), and change in %BF (r = 0.20, p < 0.05). Regarding exercise, "total time spent doing physical activity during your freshman year" was inversely correlated to change in %BF (r = 0.27, p < 0.01). Finally, differences between non-athletes and athletes were not statistically significant (p > 0.05). These findings indicate that there are significant physical changes that occur during the freshman year of college. These changes may be a result of changes in environment, caloric consumption, and decreased physical activity. However, results did not indicate that these changes include a significant increase in percent body fat.

When dealing with latency-critical applications in Kubernetes, a common strategy is to over-allocate resources to ensure the application can meet its latency guarantees during traffic surges. However, this practice often leads to resource underutilizationas the application will not fully utilize its reserved resources. The Kubernetes scheduler cannot initiate new workloads on the node because of perceived full resource utilization. This study explored the utility of two existing methods, Container Runtime Interface (CRI-RM), which we configured to use the 'balloon policy' and the vertical Pod Autoscaler (VPA) in addressing resource underutilization problems on single node Kubernetes clusters while maintaining latency-grantees of certain pods. Utilizing tc-sim, a network traffic simulator, we deployed four latency-critical and two non-latency-critical pods, all subjected to overallocation. Our finding reveals that VPA was ineffectivein detecting and addressing the underutilization of resources because of its slow response in adjusting requests inside the pods. Moreover, it worsened the underutilization issues of the node. Our configuration of the 'balloon policy' failed to detect theover-allocation issues and further led to performance degradation in the simulator, potentially due to the overhead introduced by CRI-RM. These results underscore the intricacy of over-allocation challenges in latency-critical applications, emphasizing the need for proposed-designed solutions that enable quick and dynamic exchange of resources between pods.

With the increasing scarcity of water resources, soil moisture stress is the single most threat to global soybean production causing extensive yield losses. The objectives of this study were to investigate soil moisture stress effects on all aspects of soybean growth and development processes and to develop functional algorithms that could be used for field management decisions and in soybean crop modeling. To fulfill these objectives, six experiments were conducted; one in vitro osmotic stress study on seed germination, four studies by imposing five soil moisture treatments, 100, 80, 60, 40, and 20% of daily evapotranspiration of the control at different growth stages using sunlit plant growth chambers, and one transgenerational study on seed germination at different osmotic levels and offspring growth at three irrigation treatments (100, 66, and 33% based on field capacity) for plants grown at different soil moisture levels. Two cultivars from maturity group V, Asgrow AG5332 and Progeny P5333RY, with different growth habits were used in all these studies. Midday leaf water potential, plant height, mainstem nodes, gas-exchange traits, canopy reflectance, and several yield components including pod weight, seed yield, and seed quality were measured. Soil moisture stress decreased biomass, net photosynthesis, yield, individual seed weight, maximum seed germination, protein, fatty acids, sucrose, N, and P and increased oil, stachyose, Fe, Mg, Zn, Cu, and B contents. Overall, Asgrow AG5332 was more tolerant to drought stress than Progeny P5333RY. Soil moisture stress induced changes in seed quality that were correlated with seed germination and seedling vigor in the F1 generation. These data can be used to build a model-based decision support system capable of predicting yield under field conditions.
