Den livsmedelshygieniska kvaliteten hos franska opastöriserade dessertostar :
This study was performed to investigate the bacteriological quality of French cheeses made from raw milk. Fifty cheeses of this type were purchased from Swedish retail premises. The methods described by the Nordic Committee on Food Analysis (NMKL) were used to determine the number of Enterobacteriaceae, presumptive Escherichia coli, coagulase positive staphylococci and Listeria monocytogenes. In 32 cheeses (64%) the number of bacteria mentioned above exceeded the determined maximum value. Thirty samples (60%) showed high counts of Enterobacteriaceae.
Avveckling av tomträtter
In this report a study is carried out with the aim to identify added values of EPC projects implemented in schools in order to increase the interest of EPC projects on the market. The report examines how the planned maintenance, supervision, maintenance and corrective maintenance is affected, how insurance premiums and terms are affected, the indoor environment and how the tasks of the operating staff is changing. A literature study of energy savings, energy use in schools, maintenance and insurance as well as how energy efficiency improvements are related to the Swedish environmental objectives has been made. Visits were carried out in Ludvika, interviews were also carried out with operation technicians and local strategists in Ludvika as well as employees of insurance companies.Schools often have neglected maintenance and problems with ventilation and indoor environment. Schools also have a large energy saving potential due to their low utilization, mainly because they are empty parts of the year.
Effekten av olika andelar grovfoder och kraftfoder i foderstaten på mjölkproduktion, välfärd och hälsa hos mjölkkor
Dairy cows transform grass to milk with help from ruminal microorganisms that can digest indigestible fiber in their feed. The digestive system of the cow is adapted to a diet consisting of forage and disorders like acidosis, laminitis and abomasal displacement can occur if the feed contains too much starch. To achieve the highest production possible the cow has to be given a high amount of concentrate or grain as the difference in milk yield is significant, approximately 1000 kg energy corrected milk per cow and year between conventional and organic cows that are fed a lower versus a higher share of forage. If the cow shall be able to eat the same amount of energy from forage as from grain or concentrate the eating- and rumination time gets longer and she might not be able to eat enough, which will result in a lower milk yield and will make it harder for the cow to recover from the negative energy balance that originate from the beginning of the lactation. Fat and in a sense protein content differs also depending on if the cow is given a high or low share of forage..
På egna ben? En kvalitativ studie om gymnasieelevers framtidssyn.
AbstractThe purpose of this essay was to examine how young people who are about to graduate from high school define and value their future. We also wanted to se which emotions they associate with their future and what or who influences them in their choices in life.The questions for our study were:What does it mean for these youths to become an adult?What images do they have of future education, profession and unemployment?What or who influences the picture they have of their future?What kind of attitude do they have towards the future?We approached the research with a qualitative method and interviewed ten youths in high school. Our conclusion was that the youths had an ambivalent attitude towards becoming adults; it was scary and yet exciting. The youths had the impression that education was important in order get a good job and to avoid unemployment.
Identifiering av infektion i sår, en litteraturstudie
Regardless of what discipline nurses work in, wound care is one of the tasks. Caring for wounds involves early detection of signs of infection, in order to avoid complication. Wound infection extends suffering for the patient and causes unnecessary costs for society. The aim was to describe how nurses can identify infection in wounds. Method: The design of the study was a literature review, where13 scientific articles were examined and analyzed.
Internets effekt på skatteplanering : en fallstudie
We have seen a revolution in the area of communication on a worldwide scale. We begin talking about terms as globalisation, integration and deregulation of the financial market. Companies have been tax planning for decades, the questions is if Internet has made an increase of companies than uses tax planning and which roll Internet plays. It is hard to really pinpoint all the effects of the Internet because of the relatively new area of research. This thesis will take various factors under study such as globalisation, development of the offshore industry and the fight against harmful taxation by the OECD and other organisations in order to describe the effects of Internet.
Elevers problemlösningsstrategier : En studie av gymnasieelevers val av strategier vid problemlösning
The purpose of this study is to examine senior high school students? strategies and reasoning when solving mathematical problems and make a review of the concept problem solving. The purpose is also to examine if the students? choice of strategies are influenced when their mathematical knowledge is improved.The study was conducted in two science classes at a senior high school. All the students were asked to individually solve two mathematical problems.
Rangordningens inverkan på beteendet hos nötkreatur (Bos taurus) och dess konsekvenser för djurtillsynen :
Extensively kept animals for meat production have the right to live in a good
environment. Cattle (Bos Taurus) as social animals live in small herds in the
wild. When holding animals extensively new problems have arisen regarding
human ? animal interactions. One welfare problem is to be able to come close
enough to the animals to investigate their health condition.
Biogaspotential vid samrötningav mikroalger och blandslam från Västerås kommunala reningsverk
Because of the increasing trends in energy consumption and increased environmental awareness, greater focus has been placed on improvement and development of renewable energy sources. An already proven and accepted method is biogas production from anaerobic digestion at municipal wastewater treatment plants.In the waste water treatment process solid material and dissolved pollutants are separated from the water, forming a sludge. The sludge is separated from the process and stabilized during anaerobic digestion or aerobic aeration. Most often, mesophilic anaerobic digestion is used. Because of degradation by microorganisms, biogas with a high content of methane is formed during the digestion.
Motivation for eating roughage in sows : as an indiction of hunger
Today?s feeding methods can determine the domestic pig?s abilities to fulfill basic behavioral needs, such as foraging, and the way in which pigs are feed is an important aspect. Feed does not only provide the energy and nutrients critical for survival, but feeding is also associated with a number of other factors contributing to well-being and reproduction. Today the feed for gestated sows is often composed by high energy and low dietary fiber grain products such as wheat. Three kg of this kind of feed can often be consumed by the sow within 20 minutes.
Synchronous Latency Insensitive Design in FPGA
A design methodology to mitigate timing problems due to long wire delays is proposed. The timing problems are taking care of at architecture level instead of layout level in this design method so that no change is needed when the whole design goes to backend design. Hence design iterations are avoided by using this design methodology. The proposed design method is based on STARI architecture, and a novel initialization mechanism is proposed in this paper. Low frequency global clock is used to synchronize the communication and PLLs are used to provide high frequency working clocks.
Artrikedom av kärlväxter i övergivna och restaurerade hagmarker : betydelsen av igenväxningsgrad och tid sedan igenväxning började
Continuously grazed grasslands have remarkably high plant species diversity. In Sweden this type of habitat has declined for the last two centuries. Changed land use has caused habitat fragmentation and loss of habitat quality. This has caused a great number of plant species to end up on the verge of extinction. To try to save this unique habitat and the species that are tied to it, lots of resources are laid on restoration of abandoned grasslands.
In this study, plant species richness of continuously grazed, abandoned and restored grasslands were related to degree of overgrowth, time since overgrowth started and rate of overgrowth.
Ekologisk aspekt som mervärde : En studie om långsiktig överlevnad för ekologiskt nischade livsmedelsföretag
Background: With the increased globalization food prices went down for a while, only to skyrocket to new levels. Prices of organic food, which already were more expensive than conventional, are now even more expensive. The current financial crisis results in reduced consumption which creates a threat to the smaller grocery stores. Globalization and the increased competition have had a negative impact on the environment but at the same time the desire to solve these issues has increased appreciably. The environmental aspect has been given higher priority by the individual, which led to a wider range of organic products and dramatically increased the number of stores selling organic products, leading to a greater competition among the stores selling organic food. Problem definition: What factors are important for organic retail business long term survival?Purpose: Trough case studies analyze and evaluate the organic niche retail companies? strategies of marketing.Methods: This study is based on both qualitative and quantitative research methods.
Kurs i projektarbete : Elevsyn på kursen och mina egna tankar om ett alternativ
This study has been performed at a smaller high school and with its industry students, the high school is located in a small industrial community. The purpose of my study has been to find out what students think about their work with the project work, what they think has been positive and negative, how their motivation is influenced by the work on the project and if the work has been affected by factors outside the school world.The interviews have been carried out like normal conversation with open questions. The students who participated in the study comes from the school where I did my internship. The selection was done by asking all students from a specific course, those who were positive to participate are also the ones I have chosen to interview. My main study results, in summary, described as the students, once they were inside their work were positive to the project work and felt motivated in their work. Negative experiences, for the students which attend a practical program, has mainly been economic, as the school does not provide any financial support.
Modellering av delvis kända objekt med hjälp av bilder
Today many different types of lock systems are used all over the world. Passwords, finger prints and magnetic strips are a few examples. When the key is a three dimensional object, lika a physical metal key, the security depends, in a high degree, on that you can?t copy the object without access to it. One approach to copying the object is photographing the object, and from these photographs create a copy.
