The United States Department of Defense tests its weapons systems to many different real as well as man-made environments prior to deploying the systems to the troops. The intent of testing is to insure the systems function as they are intended without adverse reactions. One of the required tests is a Radiation Hazards test to insure that non-ionizing radio frequency waves generated by transmitters, such as radios and jammers, do not cause harm to personnel, ordnance or fuel. This test is typically performed at a DoD test lab and data taken at the lab is used to determine safe operating parameters for a particular piece of equipment. This thesis presents measurements as well as mathematical models to demonstrate methods that can be employed to take more relevant Radiation Hazards data.

Studies were conducted on oats in the greenhouse and on wheat in the field to determine the effects of varying amounts of sodium and potassium upon the yield of grain and straw and upon the concentrations in the grain and straw of the following elements: K, Na, Ca, Mg, P, N, and Mn. The experiments were arranged in a randomized complete block design and the data were analyzed statistically for significant variations. Results of this investigation may be summarised thus: 1. The straw of oats and wheat contained higher concentrations of Na and Ca than the grain, while the grain or oats and wheat contained more P and N than the straw. 2. Sodium decreased the Ca content of oat grain and straw, and decreased the P content of oat straw. 3. The concentrations of the elements were more variable in the straw than in the grain or oats and wheat. 4. Potassium depressed Na, Ca and P in oat straw. 5. Potassium decreased the Mg content of oat straw, and increased the Mg content of oat grain. 6. Oats contained more Na, Ca, and Mg than wheat. 7. Manganese was not significantly affected by Na or K fertilization. / M.S.

The purpouse of the thesis was compared the comparison in the yields of hulled and naked verifield varieties and new breeding genotypes of oats. The research was conducted in the breeding station Selgen Krukanice and and it was mainly focused on the main elements of yieĺd - number of plants, cuttings, and lat per m2, toatal grain yield, the number of grains per panicle, and the quality of grain - weight of thousand grains, density and share of fixed plugs. Results of the main elements of yield was average at all genotypes of oat, qualitative parametres wasslighty below average, the reason wast dry and warm weather. Also was found good health of oats, cause of weather, that was not favorable for disease development.

This project was designed to help Hi3G Access AB’s IT department to get a better overview of the testing state in the different cross functional teams. Furthermore it was designed to identify teams and system where regression tests had the potential and the need of being automated. This information was gathered by conducting a survey designed for all the software testers at the company, followed by performing semi-structured interviews with one tester from each team. For the most suitable system and test case, an automation solution prototype was created with an automation tool using an agile test automation process model. The automation tool was evaluated regarding complexity, userfriendliness, available documentation and performance. The team and the system decided to be most prioritized and suitable was the team that worked with the Enterprise resource planning (ERP) system. The automation tool used for the prototype was Oracle applications testing suite (OATS). The project revealed that many teams at Hi3G Access AB were quite far in the automation process. The tool evaluated in the project presented itself to be straightforward and easy to learn/use. However the tool was missing a widespread discussion board and also lacked free support. / Projektet var utformat för att hjälpa Hi3G Access ABs IT-avdelning få en bättre överblick gällande de olika korsfunktionella gruppers testsituation. Vidare var målet att identifiera team och system där regressionstester hade potential och behov av automatisering. Denna information samlades in genom att utföra en enkät avsedd för alla mjukvarutestare på företaget, följt av att utföra semistrukturerade intervjuer med en testare från varje team.För det mest lämpliga system och testfall skapades en automatiserad prototyplösning genom en agil testautomatiseringsmodell. Automatiseringsverktyget utvärderas gällande komplexitet, användarvänlighet, tillgänglig dokumentation och prestanda.Teamet och systemet som valdes som mest prioriterat och lämpligt var teamet som arbetade med Enterprise resource planning (ERP) systemet. Automatiseringsverktyget som användes för prototypen var Oracle Applications Testing Suite (OATS).Projektet visade att många team på Hi3G Access AB hade kommit ganska långt i automatiseringsprocessen. Verktyget som utvärderades visade sig vara okomplicerat och lätt att både lära sig och att använda. Däremot så var avsaknaden av ett utbrett diskussionsforum ett faktum samt att produkten saknade fri support.

WestBred 881 durum commands a premium price due to its superior quality, but it produces a lower yield than other commercially available cultivars. Studies conducted at Maricopa in 1987 suggested that yields of WestBred 881 may be increased by 3-inch row spacing. Studies were conducted at three commercial farms in an effort to mimic the effect obtained with 3-inch row spacing by using conventional grain drills to obtain more uniform plant spacing. Seeding twice in parallel directions did not result in the desired effect because the seed planted in the first pass was covered by extra soil from the second pass, and the seedlings emerged from cracks made by the disk openers from the second pass. Broadcasting on beds resulted in a poor stand and non- uniform plant distribution compared to drilling the beds. Planting twice in perpendicular directions to each other resulted in a more uniform plant distribution than drilling once, but a slightly poorer stand was achieved due to extra wheel traffic and yields were not significantly increased. The best method to obtain a more uniform plant spacing may be to seed with a 3-inch drill.

Gypsum is applied to alleviate the problems associated with sodium- affected soils, such as surface crusting and impeded water infiltration. Due to the uncertainties in identifying gypsum-responsive sites, field studies were initiated to further our understanding of conditions responsible for the response of wheat to gypsum applications. Gypsum was applied at rates ranging from 0 to 4 T/A on two commercial farms near Coolidge, AZ. No differences in wheat grain yield, grain protein, stand, grain bushel weight, or plant height were detected at the 5% probability level at either site with the exception of increased plant height at one site. The positive benefits of gypsum have been documented in the past with certain soils; this study is just one of many required to more positively define gypsum-responsive sites in Arizona. The economics of gypsum application involves delivery and application cost of gypsum and the change in yield and value of subsequent crops.
