Nötkreaturs betesselektion på vallar baserade på fyra olika fröblandningar

En beteendestudie med nötkreatur utfördes under maj-september 2014 på försöksytor sådda i juli 2012 med fyra vallfröblandningar (A-D). Fröblandning A och B innehöll båda 35 % ängsgröe (Poa pratensis), 10 % Rödsvingel (Festuca rubra) och 20 % vitklöver (Trifolium repens) men skilde sig genom att fröblandningen för vall A innehöll 35 % engelskt rajgräs (Lolium perenne) och B innehöll 35 % rörsvingel (Festuca arundinacea). Fröblandningarna C och D hade arter i samma proportioner men skilde sig med avseende på sorter där C bestod av grässorter av fodertyp medan D bestod av sorter för sport ändamål. Både C och D innehöll 44 % ängsgröe, 12 % rödsvingel och 44 % engelskt rajgräs och ingen vitklöver, men vall C syftade i övrigt till att ha likartad sammansättning som A. Syftet med beteendestudien var att studera om nötkreatur föredrar eller undviker någon av vallarna.

Akustisk trädgårdskonst : att ge sonisk karaktär åt en plats

Ljud och trädgård är kanske inte det första par man tänker sig som gifta men de tus historia kan spåras längre tillbaka i tiden än man kan föreställa sig. När jag bestämde mig för att skriva min kandidatuppsats om akustisk trädgårdskonst trodde jag att ljudinstallationer i trädgårdar och parker var ett nytt fenomen. En helt ny värld öppnade sig framför mina ögon då jag insåg att så inte var fallet. Konstgjorda ljudkällor, såsom gyllene fåglar och vattenorglar, har kommit och gått genom tiderna medan naturliga ljud, såsom vind och fågelsång, bestått. När det kommer till vår egen tid är trädgårdsljud, även om moderna material och tankesätt används, en konstform som starkt präglas och inspireras av sin historia. Du kan skapa olika sorters ljudmiljöer i din trädgård beroende på vad du väljer att använda för material.

Tekniska möjligheter för artificiell spridning av renlav :

Forestry and reindeer husbandry are entitled to use the same land for their operations. For this reason, conflicts occasionally arise between them. Soil scarification is a forestry operation which has a negative effect on the occurrence of reindeer lichen. Reindeer lichens are of crucial importance to reindeers and reindeer husbandry, especially in the winter when reindeers primarily feed on different lichen species (Cladina spp. and Cetraria spp.).

Prästgårdsträdgårdar : barndomsskildringar från 14 prästgårdsträdgårdar i Växjö stift

Few rectory gardens are today remaining in their former design and the cultural heritage that they represent are disappearing. Since 1987-88 the parishes are no longer bound to keep housing for their priests, which means that they, for economical reasons, are starting to sell their rectories. With this in mind, a group of people, growing up in rectories in Småland and Öland between the 1930th and 1950th, formed an interest group to save the memory of their rectory gardens. On the basis of their memories, they have written a couple of descriptions of the rectories, which describe the gardens content, design and the life they once lived there. With this compilation of the 14 rectory gardens I want to keep the memory of them and create a ground for future work in this field. Historically the rectory gardens played an important roll as patterns and examples in the countryside.

Slaktsvins basala behov i kommersiell uppfödning : Slaktsvins basala behov i kommersiell uppfödning oönskade beteenden, skador och välfärdspåverkan

The Swedish Welfare Act § 4 says that "Animals must be kept and cared for in a good environment for animals and in such a way that promotes their health and allow them to behave naturally." Pigs in the wild spend 80% of their waking hours walking around and rooting for food, eating and exploring their environment with its snout. Fattening pigs in commercial farms spend 80% lying doing nothing. A lactating sow is lying down most of her day, and only 10-20% of the body surface is in contact with the floor, so the pressure is high on these spots. Piglets lie down and paddle with their legs, with high liquid content in the tissues, several times an hour, to stimulate and massage the sow's udder. In the existing system, these individuals are held more often on floors that are anything but inviting to sleep on.

Avskiljning av uran från dricksvatten med reaktiva filter :

Water is our most important provision and its quality is above all dependent on the geological conditions in the area from where it is extracted. Due to geological properties there are certain areas with an elevated risk of high uranium levels in the ground water, which in turn constitutes a risk for human health. Consumption of water that contains a high concentration of uranium implies a health risk due to the chemical characteristics of uranium. Livsmedelsverket (The National Food Administration) and Socialstyrelsen (The National Board of Health and Welfare) therefore recommend that precautionary measures should be taken when the uranium concentration in ground water exceeds 15 micrograms per litre. In particular, drinking water collected from wells in areas with uranium-rich bedrock may have a harmfully high level of uranium. One of the wells of the Ärla water purification plant, located near Eskilstuna, Sweden, contains water that exceeds the guideline of 15 micrograms per litre. One interesting technique for removing uranium from drinking water is adsorption to reactive filter materials.

Artificiell insemination i dikobesättningar

Den vanligaste produktionsformen av nötkött sker i dikobesättningar, där kor och kvigor förväntas föda en kalv per år. I sådana besättningar är fertilitet hos djuren en viktig faktor, då förmågan att föda fram en kalv varje år påverkar inkomsten. I Sverige används naturlig betäckning i störst utsträckning, men ett alternativ är artificiell insemination. Syftet med detta arbete är att undersöka för- och nackdelar med artificiell insemination och varför det inte används i samma utsträckning inom dikobesättningar som hos mjölkkor, samt när det kan vara aktuellt att använda sig av. Den artificiella inseminationens påverkan på dräktighetsresultat varierar mycket i studierna, från 37 till 74 %, men det antyds att 50 % är ett gränsvärde där resultat över detta kan anses godtagbara. Ekonomiskt finns fördelar så som ökade kalvvikter och mindre förluster relaterat till kalvningssvårigheter, men nackdelar i form av ökade kostnader för veterinärtjänster och mediciner samt för arbete.

Shareadox : -The paradox of service quality assurance in Sharing Economy businesses

The purpose of the Sharing Economy is to exploit unused resources between people, as an alternative to buying new and owning themselves (Gansky, 2010). Gansky (2010) argues that a major reason why the Sharing Economy has grown in recent times is, besides from the recession and people?s increased environmental awareness, the urbanization which has made people move closer to each other and in to the big cities. This in addition to an increased use of GPS technology in smartphones enables people to be constantly connected to an ever-changing network. People now share and exchange services and products from each other.

Närståendes erfarenheter av att leva med en svårt sjuk partner som fått konstgjord näring i livets slutskede :  

Bakgrund: Vid palliativ vård i hemmet förändras tillvaron såväl för den sjuke som för de närstående. Den sjuke har ofta svårt att äta vanlig mat och kan behöva tillförsel av konstgjord näring. Närstående kan uppleva ett stort ansvar för den sjukes näringsintag när han eller hon vårdas hemma. Adekvat näringsintag är av betydelse för det fysiska välbefinnandet. Men vad vi äter påverkar också livskvalitet i social, kulturell och psykologisk bemärkelse.

Dokumentation av ensilering med fokus på clostridiesporer i mjölk :

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.

Optimalt ekologiskt : att gestalta praktfulla parker som kan skötas på ett hållbart sätt

This is a graduate work at the Swedish University of Agricultural Sciences, The Department of Urban and Rural Development, Ultuna. The purpose of this paper has been to find out and describe principles for designing parks that offers good recreational and aesthetical values and require little amount of carbon dioxide emissions during their maintenance. The purpose has also been to see if it's possible to use city wastewater in some extent to assure the plants water supply and to find other means to make it less necessary to use purified water for watering. Recently made studies as well as older ones show how important green areas are in dense city structures both from a health and a climate perspective. Trees and other plants adsorbs different forms of air pollution and can also lower the temperature in the surrounding area through their transpiration.

Cultivation of Chlorella vulgaris in nutrient solution from greenhouse tomato production : a possibility to reduce nutrient levels and produce commercially interesting metabolites

The idea of using algae in different areas and exploring its possibilities is nothing new. Already in the early 1950s microalgae was explored as a possible food resource because of its high protein content. Lately there has been an increased interest in its potential for industrial use. Wastewater treatment is a possible use of algae since the algae grow well on the nutrients present in the water. This offers the possibility to grow algae for nutrient reduction and use the biomass for energy or animal feed since many alga species has a good nutritional value. Approximately 800-1000 m3 water is applied per 1000 m2 of greenhouse area during one season in a tomato production.

Påverkan på Valboåsen från verksamheter inom Svedens industriområde samt närliggande områden : hot mot grundvattnets kvalitet och kvantitet?

The aim of this work was to find out what potential contaminants from roads, residential area and businesses within Svedens industrial area that can affect groundwater quality and quantity. Data collection was from SGU, VISS, internal material from Gävleborg county Administrative Board and Gävle municipality archive. GIS software ArcGIS was used to create the map images in the work. The studied area is located approximately ten kilometers west of Gävle city and consists of the esker Valboåsen, which is a glacifluvial deposit that in its central parts consist of coarse material that is overlaid by sand, clay and silt. North of esker Valboåsen there are the river Gavleån which has an inflow to the groundwater in the esker. This inflow represents the largest part of the groundwater recharge.

Hästägares kunskapsnivå och attityder angående hästutfodring

Horse owner?s knowledge about horse feeding and nutrition is directly linked to the horse?s health and welfare. According to several studies, both Swedish and foreign, horse owners generally have inadequate knowledge about horse feeding. The housing systems and feeding routines of today differs in many ways from what horses have adapted to through evolution. Wild horses live in harem herds and roam on large open fields, spending about 60 % of the day grazing, mainly grass and herbs.

Utfodring i finmaskiga hönät : hästens ättid och skötarens arbetsmiljö

Horses are by nature herbivores, specialized on grass, and graze during the main part of the day. The horse has neither changed this basic behaviour nor the function of gastro-intestinal tract, when the horse was domesticated by man. A horse on pasture has an even production of saliva and gastric acids. The buffering effect of the saliva makes the pH in the stomach above four throughout most of the day. With abnormal long breaks of eating, the pH may decrease, causing an increased risk of gastric ulcer.
