… luminescence of an exit sign, based upon Swedish regulations. Scientific experiments have been conducted in a controlled environment, where exit sign luminescence was graded by an evaluation group. The results of these have been verified by similar experiments that took place in …
… or there actually existed amateur craftsmen. Through archaeological experiments and artefact studies I intend to investigate if it has been at all possible for a less experienced bronze caster to produce usable objects. The purpose is also to investigate and put to the test the …
Sammanfattning Laborationer i naturvetenskapliga ämnen är en naturlig del av undervisningen. Syftet med den här uppsatsen är att ta reda på om man tar bort en möjlighet till inlärning och förståelse för eleverna om laborationer inte används i undervisningen. Vidare ville jag …
… to work for tests with patch loading caused by a local moment. A number of experiments were made, for which two parameters were varied, the thickness of the web and the length of the attachment. The loaded attachment was made very stiff, because it should not be deformed in …
… sometimes given. By modifying the aeration control strategy three full-scale experiments have been made, with the intention to reduce the air consumption. The experiments were carried out during week 37-50 in the autumn of 2006 and showed that savings could be made. The regular …
test av olika filtertekniker avsedda för enskilda brunnar
… distribution of arsenic and factors governing that distribution are discussed. Experiments regarding As removal by different filter techniques were carried out in a small water purification plant in the village of Lästringe, located 40 km NE of the city of Nyköping. Only ground …
… (IOCO) and an anion exchange resin (Purolite). The study included batch experiments with artificial water, from the Ärla water purification plant, and water from a stream near the Stripa mine, both sites having uranium levels higher than 15 micrograms per litre. The results that …
… of a rest by product from ethanol production, called drankvatten. Laboratory experiments were carried out with two process sets, each with two continues stirred tank reactors (CSTR). The process consisted of a thermophilic (55ºC) reactor as the first step in which the substrate …
Studie av alternativa mätmetoder
… measurement methods have been estimated through literature study. Laboratory experiments were conducted on two measurement systems, designed from two differential pressure methods. From the result from these experiments, a system for field measurement was designed from the lab …
… maximal performances in bench press the participants was divided into two experiments groups and one control group. Intervention groups performed a specifically designed push up program on a vibrating plate respectively a step board during 12 weeks Initial load at 60 % of 1 RM …
metodutveckling och tillämpning avseende odling och resistensstudier mot komplement, särskilt interaktion med faktor H
… phagocytosis with the aid of microscopy and FACS was performed. The culturing experiments showed Borrelia to be rather easy to culture, although a strict sterile technique has to be applied. Concerning sensitivity to complement, the B.afzelii strains showed to be resistant to …
fördröjd groning hos raps : försök med frö-coating samt litteraturgenomgång om frögroning, coating och praktisk tillämpning i reläodling
… enable the seed to take up water and germinate. The results from the experiments showed that it is difficult to find a chemical, which can meet the requirements of delayed germination with a built-in time factor. The acid fraction was shown to harm the seed while breaking down …
… of liming and Ca2+ on the Cd uptake by carrots. In order to do that, two experiments were conducted. The long-term experiment was conducted in a climate chamber where the carrots were grown in a sand/peat substrate for eleven weeks. Two levels of Cd were tested, 0.23 and 2.3 …
… significant. Experiment arrangement and implementation for this type of experiments could be revised in order to better consider stem rust. Measurements of microclimate are not reliable as a forecasting method. Our experiments show that the temperature and humidity throughout …
… enhance nutrition use efficiency in agriculture. This thesis consists of two experiments, growing microalgae in drainage water from a clay soil and cultivating algae for maximal growth. Both experiments were performed in our photobioreactor. The algae cultivated in drainage …
