1	Incorporating cover crops into successful corn production systems in the Mid-south Mullican, Nolan 13 August 2024 (has links) (PDF) Cover crops are known to produce many conservation benefits. However, grower adoption remains low due to various issues and poor economic returns. This study was conducted to identify factors and management practices needed to integrate cover crops into Midsouth corn production systems. The effects of cover crop species, herbicide termination timing, and mechanical termination methods on the growth, grain yields, and economic returns of corn [Zea Mays (L.)] were investigated in Mississippi. The presence of living cover crops at planting stunted corn growth when they were not terminated by herbicides at least four weeks preplant. A legume cover crop reduced corn yield only when it was terminated at planting. The inclusion of a legume benefited the system compared to cereal rye. Cover crops produced neutral to negative crop yields, and all treatments reduced economic returns. Negative economic returns and production risks will likely limit cover crop adoption by corn growers.
2	Framtagning av ny cykelbelysning med ljussignalering / Development of new bicycle lights with signal lights Ghorbani, Nathalie January 2018 (has links) Syftet med projektet var att ta fram en ny cykelbelysning för att höja cyklisters säkerhet och förenkla trafikregler samt utförandet av signalering. Genom en nulägesanalys av befintliga produkter, elektronikkomponenter och slutanvändarnas uttalanden kunde kundbehov tas fram. Därefter rangordnades kundbehoven och en funktionslista tillsammans med en produktspecifikation kunde verkställas. Med dem som grund utfördes en idégenerering med flera olika lösningskoncept där ett val gjordes baserat på en Kesselringmatris. Det vinnande konceptet var ett par pedaler med integrerad belysning. Genom en accelerometer fungerar pedalen som en bromslykta och med hjälp av en extern kontroll kan körriktningsvisare sättas igång som projiceras på marken. Elektriciteten som behövs till pedalernas belysning genereras när cyklisten roterar pedalaxeln via en generator. Som slutsats uppfylldes projektets mål men mer arbete behöver göras kring projektets avgränsningar för en färdig produkt. / The purpose of the project was to develop a new bicycle light in order to improve cyclists’ safety and to make it easier for them to follow traffic regulations. Using a status analysis of existing products, electronics and the end users statements the customer needs could be documented. Then the needs were ranked and a function list together with a product specification was produced. With them as a base the brainstorming could begin where multiple concept solutions were made and one of them chosen as a winner through a Kesselring matrix. The winning concept was a pair of pedals with integrated lighting. With the help of an accelerometer the pedal worked as a brake light and with an external control system turn signals could be turned on and were projected on the ground. The electricity needed for the pedals light system is generated when the user rotates the pedal axis with the help of a generator. As a conclusion all the project goals were fulfilled but more work needs to be done regarding the projects limitations for a complete production ready product.
