Establishment and evaluation of a Barley starch isolation method with focus on representability

The high viscosity of barley material makes starch isolation problematical using regular methods established for cereals. An adjusted starch isolation method has been set up for barley, based on fractionation and purification. The focus is on attaining truly representative isolates of six flour samples selected for widely differing characteristics within the research program BarleyFunFood (BFF). Beside establishment of the method, this diploma work aspires to serve the BFF with isolated material of sufficient yield valid for further starch characterisation. A pre study was conducted evaluating available wet mixing equipment, experimental conditions and mode of procedure.

Inpackning av giveaway-produkter

We performed our thesis at SCA Hygiene Products in Falkenberg. Our task has been to present a suggestion for a solution of the packing of giveaways that the company uses.In the current situation the work is performed manually, and the company wants to automate the process. In the following report, we present the different solutions that we have developed in our definite model. It includes a picking solution, a shaking table and trays. The product choices we have made are based on existing solutions.To help, we have used Fredy Olsson's books in principle and primary structure.

Produktivitet vid stubblyftning :

Stump wood was used between 1850 and 1950 for production of tar and as firewood. In the 1950s the use decreased because of the introduction of the cheap fossil oil. In the 1970s stump wood became an interesting issue again as a raw material for the pulp industry. Stump lifting has today become a possible source for bioenergy. The objectives with this study were to investigate the productivity of stump lifting and stump extraction, and to analyse the economy.

Den upplevda kroppen : Ett erfarenhetsbetonat möte med Skip Arnold

Studien undersöker huruvida förståelsen av tre kroppsorienterade videokonstverk avSkip Arnold kan beskrivas utifrån pragmatismen och John Deweys erfarenhetsbetonadeestetikbegrepp. Syftet är att studera hur kroppen präglar mötet mellan verk och åskådaresamt hur betraktarens eget erfarande av kroppen kan fungera som utgångspunkt förförståelsen. Studien innefattar tre pragmatiskt inspirerade analyser av verken Girls inbikinis, Head Shaking #2 och Breathing. I samklang med det erfarenhetsbetonadeestetikbegreppet införlivas mina egna erfarenheter av företeelser som vanligtvis intebetraktas som estetiska för att studera förståelsen. Analyserna präglas av ettfenomenologiskt tänkande som vetenskapliggör människans erfarenheter.

Otitis externa hos hund ? förebyggande åtgärder och råd till djurägare

Otitis externa is a disease regularly encountered in veterinary practice. It is estimated to be the most common disease in the external ear canal of dogs and treatment is often delayed due to unfortunate pet owner ignorance. Owners tend to assume that scratching of the ears and head shaking are natural behaviours in their dog and may be neglecting the problem unknowing of how severe it actually is. A literature study has been carried out to examine the causes of otitis externa in order to present a collection of measures that can be used in the treatment and prevention of the disease. In turn these measures can be advised to the dog owner and used in the home environment to make the best qualifications for healthy ears in the dog. The causes of otitis externa have been divided into predisposing, primary, secondary and perperuating causes.

Fosforavskiljning i reaktiva filter vid småskalig avloppsrening

An excessive input of nutrients to lakes and other water bodies has created a problem with eutrophication in Sweden. Untreated, or partially treated, domestic sewage is a major source for discharge of phosphorus (P), which is the nutrient most frequently responsible for eutrophication of most fresh waters and the Baltic Sea. The waste water can be cleaned by filter materials, which have a high P-retention ability and which after saturation may be used as fertilizers. Four potentially suitable filter materials were tested in batch- and column experiments in this study. In the batch experiments, the following materials were shaken with waste water in time series ranging from 5 seconds to 60 minutes: coarse (1-4 mm) and fine (0-2 mm) Polonite® (heated bedrock from Poland); Filtralite® (light expanded clay aggregates with limestone added before burning); water cooled blast furnace slag (BF-slag) and BF-slag mixed with 10% burned limestone.

Metodik för utmattningsberäkning av svets i vibrationsmiljö

In this work, a method was developed and evaluated for calculating the life of welds under the influence of fatigue loads from a vibration environment. Typically, a shaker table is used for testing a component against vibration loads. The shaker table creates a vibration environment that is defined in the frequency domain by a power spectrum.Similarly, a virtual vibration table can be used to calculate the same type of load environment, which can then be used to calculate the expected lifetime. The benefit of this method is that it can be used in design, as well as in simulation of tests before physical verification tests are carried out.Today there are methods for calculating fatigue life of non-welded base material, but since many components contain welded joints, there is a need to apply this method to those types as well. To achieve this, the thesis combines two different areas, which together provide a method for fatigue assessment of welds using a virtual shaker table.The methodology is carried out by modeling the component, and its welded joints, in a finite element program.
