Arboga Mekaniska Verkstad : Förslag på saneringsåtgärder gällande gjuteriet och plåtverkstaden
The inDustrialization in Sweden has increased the large number of areas that have been contaminated with various types of pollution. One of those sites are the property Höjen 3:24 in Arboga where ?Arboga Mekaniska Verkstad? once been. The property wants to increase the use of the old former foundry building with the adjacent ?plate-workshop? and believe there are two options for the building: That the building either should be used as a warehouse/concert hall, or rebuilt into a cultural center. An environmental evaluation has shown that the levels of heavy metals are over the Swedish environmental protection agency guidelines of less sensitive land.
Comparison of stable environment in prior approved and non-prior approved horse stables
To establish good horse welfare there are several factors that need to be considered. One important factor is the environment in which the horses are kept. In Sweden horses are stabled during long periods of time in the cold season and consequently the stable environment is even more important. The most essential environmental factors in a horse stable are ambient temperature, relative humidity (RH) and concentrations of contaminants in the stable air. The air in a horse stable contains Dust, noxious gases, moulds and microorganisms which all can contribute to developing respiratory diseases in horses.
Miljöeffekter av alternativa system för behandling av hushållsavfall i Santiago, Chile : en jämförelse mellan deponering och förbränning med energiutvinning
This report was written by Lisa Bengtson and Hanna Paradis and describes the
degree thesis "Environmental impacts of solid waste treatment in the Metropolitan
Region, Santiago, Chile ? a comparison between current system and incineration
with energy recovery". The purpose of this thesis was to investigate if incineration
with energy recovery could be motivated through an environmental perspective as
an alternative to landfilling of solid waste in Santiago, Chile. The study was
performed with Life Cycle Analysis as a theoretical base.
In Santiago, situated in the thirteenth region of Chile, Región Metropolitana, lives
6,5 million inhabitants. The major part of the solid waste produced in the region is
landfilled on three different sanitary controlled landfills situated outside the city
center.
HANDSFREE-ENHET FÖR MOBIL TRYGGHETSTELEFON
Cnior Mobile AB i Lindesberg utvecklar en mobil trygghetstelefon för äldre. Detta examensarbete går ut på att utforma en handsfree-enhet för denna. Handsfree-enheten ska integreras i larmknappen, som bärs av användaren runt handleden, och har kontakt med telefonen via blåtandsradio. I examensarbetet ingår att välja ut lämplig högtalare och mikrofon, hitta lösningar för smuts- och vattentålighet samt att lösa problem med ekon och bakgrundsstörningar.En högtalare hittades som uppfyllde kraven för smuts- och vattentålighet samtidigt som den hade utmärkt frekvensgång för återgivning av tydligt tal. Vattenavrinning från högtalaren löstes genom att ett sinussvep sänds ut från högtalaren varje gång ett samtal ska kopplas upp.
Salmonella prevalence in the poultry feed industry in Pakistan
Abstract
One of the leading causes of food borne infections in the world is due to Salmonella by con-suming poultry products including eggs and meat. According to US Food and Drug Admin-istration (2009), 2 to 4 million cases of Salmonellosis in humans occur every year only in US. Salmonella causes wide range of diseases with enteric and typhoid fever, food poisoning, di-arrhea and gastro-enteritis. Many serotypes of Salmonella do not have host specificity and cause disease in all kinds of animals and humans. Salmonella has capability to modify accord-ing to the changing environment and it can develop resistance against routine elimination practices of sanitation, chemical treatments and antibacterial drugs.
Newly established poultry inDustries in Pakistan are confronting various infectious diseases including Salmonellosis while in Sweden Salmonella prevalence in animal products con-sumed for humans is extremely low.
Utsidan räknas : ?En materialstudie
Judged by appearance. This is the conclusion of research made on shopper behavior that revealed that consumers tend to go by their instinct when evaluating vacuum cleaners in a purchasing situation. Many buy the first vacuum cleaner they interact with and few buy pre-planned brands. Almost none even turn the machine on before taking a purchase decision.Electrolux Floor Care Europe has their factory for vacuum cleaners in Hungary. Increased competition from China makes it harder to "only" produce vacuum cleaners with good performance.
Utvärdering av lufthalts- och nedfallsmätningar gjorda vid Korsnäsverken : Samband mellan miljöförbättrande arbete i pappers- och massaindustrin och föroreningar i närområdet
En nedgång har setts i Sverige och Europa när det gäller luftföroreningar de senast årtiondena. Nedgången beror bland annat på minskade emissioner från inDustrier, övergång från uppvärmning med olje- och kolpannor till fjärrvärme och förbättrad bränslekvalitet. Denna studie utvärderar lufthalts- och nedfallsmätningar gjorda i närheten av pappers- och massainDustrin Korsnäs i Gävle. Mätserierna startar vid sent 1970-tal och går fram till årsskiftet 2009/2010. Nedfall av stoft, sulfat, natrium, kalcium och lufthalter av svaveldioxid samt sot studerades.
Förbränning av biobränsle på Saugbrugs pappersbruk : Variation i rökgasstoftets sammansättning
Norska pappersmassainDustrin Norske Skog Saugbrugs AS använder flera olika biobränslen i en bränslemix vid produktion av ånga för internt bruk. Biobränslen visar stora variationer i asksammansättning och producerad askmängd, varför syftet var att studera dessa i förhållande till bränslemixen, via en statistisk analys av Saugbrugs befintliga data. Rökgaserna från förbränningen renas med ett elektrofilter med tre avskiljningsfält för askstoftet, och en teori om fraktionering av aska från de olika fälten vad gäller innehåll av ekotoxiska metaller fanns. Provtagning, analys av partikelstorlek och laboratorieanalys av askstoft i rökgasen samt aska avskilt av de olika fälten i elektrofiltret var därför motiverat. Förbränningen som helhet alstrar stora mängder aska som sedan deponeras.
Omvårdnadsrutiner för katt med astma
Feline asthma is a condition very similar to the respiratory disease affecting humans. It is causing, among other things, a constriction of the bronchial airways, an increase of mucus production and damage to, or erosion of, the epithelial membrane. The symptoms occur intermittently and do, in most cases, evolve during a long period of time.
The aim of this essay was to investigate whether there are any nursing routines for feline patients with asthma in animal clinics and animal hospitals in Sweden, and if so, to compare similarities and differences. A literary study of research material also led to a suggestion of how to form a nursing routine for this type of patient.
Strötorvsanvändning i djurstallar : en litteraturgenomgång
Peat litter has been used in animal houses for a long time. Because of its good ability to absorb liquid and nutrients from the manure it can create a dry surface for animals and a valuable manure product. Through changes in agricultural practises the use of peat litter has diminished and is to a great extent replaced by straw, sawDust and cutter shavings although Sweden is rich in peat-findings.
The aim of this work was to summarize the presented knowledge about the used of peat
litter, techniques, advantages and disadvantages and to compare with other commonly
used litter materials. Articles on peat litter have been searched for in magazines, databases and books at SLU library. Visits to peat inDustries, interviews with peat producers and with peat researchers contributed to the material.
Peat is not a uniformly material.
