The interest for locally produced food is increasing due to consumer concern about the environment, distrust of industrial foods and a demand for high quality products. Apple is the predominant fruit crop in Sweden, and by processing apples into cider and vinegar, these products could significantly contribute to the development of the market of local foods.In this study different yeast types and different bacterial cultures were evaluated for their suitability in cider and vinegar production from cloudy apple juice. Ten apple cultivars (Aroma, Baldwin, Belle de Boskoop, Bramley, Cortland, Gravensteiner, Ingrid-Marie, Jonathan, Rubinola and Spartan) were also evaluated for their suitability for production of juice, cider and vinegar. Chemical analyses including total soluble solids, titratable acidity and total phenols were performed on the products along with sensorial evaluation by taste panels.The yeast strains were shown to have an effect on fermentation rate and the resulting content of total phenols in ciders fermented from cloudy apple juice. Dry commercial starter strains gave a higher appreciated cider compared to cider that was spontaneously fermented, and the ale yeast Safale S-04 was concluded to be the most suited for fermentation of cloudy apple juice.For vinegar production, the bacterial culture had an effect on TSS, but not on any other chemical or taste characteristics.

To produce milk of good standard the feed for the animals kept for milk production is an important part in the work of quality. This makes it important to feed them with good forage, especially when feeding with silage. The process of making silage is very complex and requires a careful handling to be successful. The fundamental idea is to create an anaerobic environment in the herbage to favour the desirable micro-organisms, in this case the lactic acid bacteria. This environment is created by careful handlings were the importance is to pack the crop well and cover it as soon as possible to exclude oxygen.

AbstractThe purpose of project is to study the possibility for Borås Energy & Environment to build and run a commercial ethanol production facility in Borås. The project also studies the technology for the production of ethanol using renewable energy, e.g. lignocelluloses with focus on two processes, svag-syra hydrolyse and enzymatic hydrolyse. The technology of the process is based of hydrolysation of biomass (hemicelluloses and cellulose) to sugar and extract it to ethanol. These two techniques will compare with each other to determine which of them that it?s more suitable for ethanol production.

Vitamin A och dess derivat har en avgörande funktion i kroppen, både hos dräktiga tikar och hos övriga hundar genom att påverka synförmåga och tillväxt av epitel samt andra viktiga cellulära mekanismer. För att fosterutvecklingen ska fungera normalt behöver moderdjuret få i sig tillräcklig mängd vitamin A via kosten. För höga mängder kan däremot ha en skadande effekt och leda till missbildningar hos fostret. En av de vanligaste missbildningarna orsakade av ett överintag av vitamin A är gomspalt. Syftet med den här litteraturstudien är att beskriva hur den normala utvecklingen av gommen går till och genom vilka mekanismer ett överintag av vitamin A hos moderdjuret kan bidra till uppkomst av gomspalt hos fostret. Utvecklingen av gommen börjar med ett intramaxillärt område som uppkommer genom sammanfogning av tre olika vulster, två från överkäken (maxillarvulsterna) och en från näsområdet (nasofrontala vulsten). Det intramaxillära området består av tre delar varav den ena utgör den primära gommen.

The milk production has developed rapidly the last years. The milk production per cow is increasing and the production units are larger with an increasing number of animals and a decreasing number of workers. Many milk producers invest in automatic milking systems (AM) to meet this change. In these systems the cows can voluntary decide milking frequency and usually the milking frequency are higher than two times per day. But how does the milking frequency effect the composition of the milk? The aim of the present study was to study the effect of milking frequency on the milk composition and the milk fat quality.

Urbaniseringen i Kampala växer snabbare än den ekonomiska tillväxten, vilket skapar en stor grupp människor med så svag köpkraft att de inte kan köpa mat för dagen. En lösning på problemet är att odla sin egen mat, men med de begränsade landarealer som en växande befolkning leder till, finns det inte tillräckligt med mark att odla eller bedriva extensiv boskapsproduktion. Bönderna tvingas därför att utfodra djuren med de biprodukter som genereras från hushållet och från den lokala marknaden. Uganda är en av världens främsta bananproducenter, där den större delen av produktionen går till landets egna humankonsumtion, vilken i sin tur genererar enorma kvantiteter bananskal varje år. Bananskalen säljs på de lokala marknaderna och utgör en billig foderkälla till framförallt idisslare för Ugandas bönder.

Milk fat is an important feature in many different milk products and other foodstuffs and it is often crucial for the dairy plants that the milk fat is stable for different manufacturing processes. Lipolysis is the enzymatic degradation of fat and is the one of the causes for an elevated amount of free fatty acids (FFA) in milk. Further, the change in fatty acid (FA) composition in milk can affect the stability of the product and also the manufacturing process. Both internal and external factors, at farm level or at the dairy plants can affect both FA composition and content of FFA. Milking frequency (MF=number of milkings per cow and day) and the composition of feed are two examples of factors generally performed at farm level. The objective of the present study was to evaluate how FA composition of milk and amount of FFA are influenced by two different ingredients supplemented to concentrate.

Diabetes mellitus is an endocrine disorder affecting a range of different mammals, including dogs, cats, horses and humans. Worldwide, 347 million people have diabetes, and the disease is an increasing burden on the world?s poorest countries. The disease is characterised by chronic hyperglycaemia and afflicted individuals experience increased thirst, polyuria and weight loss, sometimes despite increased appetite. Diabetes mellitus is either insulin dependent or non-insulin dependent.

The purpose of this retrospective study was to investigate the prescription of antibiotics to dogs at the small animal clinic at Ecole Nationale Vétérinaire, Nantes, France. The purpose was also to compare the possible prescription patterns in France with those seen in a similar study by Petersson (2003) at the small animal clinic at the Swedish University of Agricultural Sciences, Uppsala. Antibiotics are very important in veterinary medicine and are used both to treat infections and to prevent them. The use of antibiotics however is not without complications and the risk of developing antimicrobial resistance is of most concern. Resistance has been shown to exist against all currently known antibiotics and potentially all pathogenic bacteria could develop resistance to one or more antibiotics. This study analysed the case records for all dogs presented to the small animal clinic at Ecole Nationale Vétérinaire, Nantes, France during October 2001 and March 2002 to identify patients which were treated with systemic antibiotics. For these cases the antibiotic used, classified according to the ATCvet system, and the indication for use was noted. A total of 292 cases (146 per month) resulted in administration of systemic antibiotics.

Bakgrund: Denna litteraturstudie handlar om avnavling och när det är optimalt att avnavla det fullgångna friska barnet. Avnavling har länge varit ett diskuterat ämne bland obstetriker, barnmorskor och föräldrar. Föreliggande studie ska bidra till att öka barnmorskans och övrig vårdpersonals medvetenhet om när avnavling bör ske och när det är fördelaktigt för barnet att avnavlas. Rekommendationen är att friska fullgångna barn avnavlas sent om inte situationen kräver en tidig avnavling eller att föräldrarna önskar tidig avnavling pga. donation till biobanken.

Sammanfattning Kisel (Si) är det näst vanligaste ämnet (drygt 25 %) i berggrunden. Bara en del av detta är tillgängligt som monokiselsyra, den form i vilken kisel är upptagbart för växter. Jordens kiselinnehåll är beroende av bergets vittring. Mycket höga halter av kisel återfinns i naturen i vulkaniska substrat (pimpsten innehåller drygt 66 % Si och scoria närmare 47 % Si), i diatomit (ett mineral bestående av resterna från encelliga kiselhaltiga alger, s.k. diatoméer) innehållande 66 % Si, scoria approximatly 47% Si), in diatomite (a mineral consisting of the remainings of single celled algae, diatoms containing < 40 % Si) and in some clays (30-60% Si).

Uttaget av biomassa har ökat i det svenska skogsbruket. Energi från biomassa är en viktig del i att Sverige nu uppnått EU´s miljömål om att minst 50 % av vår energiförbrukning skall komma från förnyelsebara källor. I och med en ökad förbränning av biobränslen bildas också mer vedaska som idag till största del deponeras. Aska är starkt basverkande och innehåller alla de mineralnäringsämnen, förutom kväve, som träden under sin tillväxt tagit upp. Ett ökat biomassauttag och ett intensivare skogsbruk ger en ökad naturlig försurning, och en ökad bortförsel av mineralnäringsämnen.

This study aims to assess the normal inflow of extraterrestrial chromite to Earth. The results from the investigationare compared to earlier studies of middle Ordovician Orthoceratite Limestone in which 1 - 3 extraterrestrial chromitegrains ( >63 ?Êm ) per kilogram limestone were found. These values have been interpreted as evidence of a twoorders of magnitude increase in the flux of extraterrestrial matter to Earth during a part of middle Ordovician.From an early Paleocene marine sedimentary sequence with known sedimentation rate in Zumaia, northernSpain, 90,5 kilogram of condensed limestone, dated to about 63 Ma, was sampled. The limestone was dissolved inhydrochloric- and hydrofluoric acid and the residue was sieved and searched for opaque minerals under the binocularmicroscope.

Syftet med detta projekt var att studera inverkan av gröda och skördetidpunkt på kemisk sammansättning och vomnedbrytning av neutral detergent fibre (NDF) och torrsubstans (TS) i helsäd samt att jämföra ANKOM DaisyII in vitro-metoden med in situ-metoden med avseende på nedbrytningsförloppet i vommen av NDF och TS i helsäd. Havre, korn, rågvete och vårvete odlades i storrutor med tre upprepningar i fält. Hela försöket upprepades under två år (2002 och 2003). Varje storruta delades upp i två smårutor, som skördades vid tidig mjölkmognad respektive tidig degmognad. In vitro-inkubering skedde med ANKOM DaisyII-inkubator av 48 prover från båda åren.

The aim of the project was to develop a method to investigate differences in adhesion of microorganisms to materials that contains lignocellulose. The method was tested on a gram-positive (Micrococcus lutea) and one gram-negative (E-coliJM109) bacteria.The study was begun by cultivation of the two microorganisms. The cultivation was done to calculate the generation times of the bacteria and to obtain growth curves. Cells from these cultivations were also frozen (-70ºC) and later used for inoculation.At STFI-Packforsk AB the total charge on the mass was measured and later a conductivity titration on the mass was executed as well, all to find out more about the different properties of the mass. Properties that in a later part of this study could possibly be linked to the adhesion of cells to the pulp.
