Vegetarisk kost och dess påverkan på den orala hälsan
Många faktorer påverkar den orala hälsan, däribland kosten. Idag finns många olika kosttyper samt livsstilar, och något som ökar i Sverige är den vegetariska kosthållningen. Syftet med denna litteraturstudie är därför att kartlägga vilken inverkan vegetarisk kost har på den orala hälsan. Artiklarna som användes i denna litteraturstudie hämtades från databasen PubMed, och studiernas referenslistor granskades kritiskt. Det upptäcktes också artiklar genom referenslistgranskningen.
Lågstadiebarn och stress : Ur ett skolmiljöperspektiv
This study is about the use of textbooks in teaching English as a second language and about teachers? attitudes and opinions of using textbooks during lessons. The aim of the study is to receive a deeper understanding of the use of textbooks in English teaching and to learn about why teachers choose whether to use the textbook approach or not. The study contains an analysis of the textbooks the teachers in our study used. The analysis shows the actual content and the types of texts together with the design and the structure of the textbooks.
Arbetssätt och ätande vid ett kommunalt äldreboende
According to The National Board of Health and Welfare, about 200 000 elderly persons get some help or support with eating or nutrition problems. This was approximately 2 percent of the population. Older people in sheltered accommodation in community care were not able to manage their own nutrition. The older people were dependent on the food that was offered to them, when and how the food was served. This was a specific responsibility for the nursing staff.
Varför blir inte barnen av med sina huvudlöss?
Över hela världen anses huvudlusen (Pediculus humanus capitis) vara den vanligaste ektoparasiten hos människa. I Sverige säljs det ca 100 000 förpackningar med avlusningsmedel varje år, så problemet är uppenbart. Resistensutveckling hos huvudlöss tros vara en viktig orsak till ökningen av dessa parasiter. I maj 2010 kom Läkemedelsverket ut med nya behandlingsrekommendationer där medicintekniska produkter är förstahandsval. Malation respektive permetrin ligger på en tredje respektive fjärdeplats i denna rekommendation.
Bergkyla och bergvärmeutredning för industrilokalen Rödbergsmyran 5 i Umeå, Västerbotten.
Grubbe Ventilation AB is a sheet metal and ventilation company who provides design, installation, service, and repair of ventilation. The company is expanding their business by building a new facility in Umeå, Västerbotten. The property is designed to be used for both office and industrial work.Grubbe Ventelation AB has not yet decided upon wish system which is to be established to provide the building with heating and cooling. The consulting firm Umeå Projekt Team has therefore been asked to investigate the possibilities to invest in geothermal- heating and cooling.If the investigation of a geothermal heating- and cooling system would provide favorable results it would be a very appropriate alternative that provides energy at low costs and are an environmentally friendly option as the energy comes from stored solar energy in the ground is provided by stored solar energy in the ground.The facility ´s heating and cooling consumptions are calculated in the program BV2 and the result indicate a heating demand of 185 000 kWh per year due to thermal transmittance, transmission losses, heating of warm water and a cooling requirement of 5500 kWh.Three different systems of geothermal heating and cooling were tested in the computer program Energy Earth Design. The results show no difference in the dimensioning of the drill hole if merely heating were to be used or both heating and cooling were to be established.
Brucellosis in small ruminants : an investigation of knowledge, attitude and practices in peri-urban farming around the region of Dushanbe, Tajikistan
Landlocked Tajikistan is situated in Central Asia and is not only the smallest republic of Central Asia, but it is also one of the most mountainous with some of Central Asia?s highest peaks. Tajikistan is currently and historically the most financially disadvantaged country within Soviet Union/Russian territories.
Agriculture is the main occupation for more than half of the country?s population. Unfortunately, however, only 7% of Tajikistan is arable land and the agriculture productivity is low.
Högprestandakugghjul
Kugghjul är ett av de viktigaste elementen som finns i en maskin. Kuggväxlar har den högsta verkningsgraden bland kända energiomvandlare idag. Kuggväxlar har höga krav och det krävs en robust konstruktion för att göra dem okänsliga för störningar. Störningar på kuggväxlar ger upphov till transmissionsfel. Transmissionsavvikelser orsakar olika typer av oönskat beteende som exempelvis utmattning och buller är ofta en följd av tillverkningsavvikelser.I detta arbete har ett kommersiellt program, Helical3D, som bygger på kontaktmekanik och finita element metoden används för att studera inverkan av tillverkningsavvikelser på växelns prestanda i form av kontakttryck och transmissionsfel.
Is the Use of the Rubber as a Preventive Measure to the Spread of HIV/AIDS Morally Justifiable? Ethical Reflections on the Controversy
Since the Human Immunodeficiency Virus (HIV) that causes Acquired Immune Deficiency Syndrome (AIDS) was discovered in the 1980s, the condom has scientifically proven to be the only technological device that can prevent transmission of the virus during sexual intercourse. This technical approach to the HIV has strongly emphasized that prevention is only possible if the condom is properly used. However, as a technological artifact the condom has shown that its use is laden with values. The question of values on condoms has brought in a heated debate on the moral justifications of its use. In Malawi, just as in other African countries, the Faith Community has rejected the Governmentsplea to promote condoms as the preventive measure against the virus.The Faith Community has emphasized on abstinence and mutual faithfulness as the only reliable means to the prevention of HIV/AIDS.
Variation i fruktsamhet hos semingaltar
Artificial insemination (AI) has had a great influence on the development of pig production and is today widely practiced (Gerrit et al., 2005). With AI, genetic progress can at a short period of time be spread worldwide compared with using natural service and the best boars can be intensively used. This is also one of the biggest risks with AI; the impact of semen containing a genetic disease or contamination of pathogens can be enormous. Fortunately, it is a small risk of disease transmission due to many tests of the boars and the semen before use (Maes et al, 2008). It is important that the boars used for insemination have good breeding values along with good reproduction features and have good fertility results (Robinson et al., 2005).
Den svenska versionen av Children?s International Mucositis Evaluation Scale : - Tonåringar och föräldrars åsikter om instrumentets frågor
ABSTRACTBackground: In all cancer therapies occurs more or less side effects, there one of them are mucositis. Symptoms of mucositis include wound and blister in the oral mucosa and affects 50-80% of children undergoing cancer treatment. Today there is no Swedish tested assessment scale for mucositis.Aim: To describe how teenagers with cancer and parents of children younger than 12 years with cancer perceive issues in a mouth-assessment instruments, Children?s International Mucositis Evaluation Scale (ChIMES), that have recently been translated into Swedish.Method/Design: The study was a quantitative descriptive research design. The participants were teenagers with cancer 12- 18 years (N=15), and parents (N=15) of children younger than 12 years.
Muntliga källor från Rystad : Intervjumetoden som historiebruk
AbstractHow do we remember? What do we remember? How does the memory change over time? These are the main questions in this essay.Five persons, who have lived or are still living in the old parish Rystad, situated seven kilometers from the town Linkoping south of Lake Roxen, have participated in interviews. They have been given the possibility to present their oral history which has been recorded and later transmitted to texture. The participants represent different social backgrounds and professions and they were born between the years 1920 ? 1936.
Genetiska studier på fågelinfluensa :
In the spring of 2006 we had our first outbreak of avian influenza of highly pathogenic H5N1 (HPAI) among wild birds in Sweden. This disease have impact on poultry industries world wide. Sporadically the virus infects other species than birds and we now know it can even cause fatal infection of humans. There are not yet any confirmed cases of transmission of the disease between humans though a suspected case in an Indonesian family is under investigation. If a mutation occurs that changes the pathogenicity and host affinity to humans we are at a risk of a new pandemia, perhaps like the Spanish flu in 1918-1920.
Cross-sectional study of the prevalence of Babesia bigemina in Uganda : wildlife-livestock interface at and around LMNP
Ticks and the diseases they transmit are of major importance throughout the world. In Uganda, cattle are the most important livestock from an economic point of view. Livestock keepers fear bi-directional transmission of tick-borne pathogens between their livestock and wild animals. This cross-sectional study was conducted to establish and compare the sero-prevalence of the tick-borne pathogen Babesia bigemina among randomly selected Ankole Long-horned cattle and European crossbred cattle on 30 farms in Kiruhura district, in two sub-counties near Lake Mburo National Park in South-western Uganda. Half of the farms were situated in close proximity to the park and thereby housed cattle with more frequent wildlife-livestock interface (Sanga), whereas the other half had less frequent contact (Kikatsi).
Patientens kunskap om parodontit före och efter icke kirurgisk parodontal behandling utförd av tandhygienist : En kvantitativ studie
Parodontit är en kronisk inflammatorisk sjukdom, som orsakas av patogena bakterier som fäster på tändernas ytor, där de bildar plack. Sjukdomen kan förebyggas genom god munhygien. Syftet med studien var att beskriva och jämföra parodontit relateradkunskap och dess relation till munhygiensvanor hos patienter före och 1-år efter icke kirurgisk parodontal behandling utförd av tandhygienist samt jämföra om det föreligger någon skillnad i kunskap efter behandling mellan två olika munhälsoundervisningsprogram. Ett ytterligare syfte var att beskriva om det föreligger någon skillnad i kunskap om parodontit med avseende på ålder, kön och utbildningsnivå. Studien var en beskrivande, jämförande studie med kvantitativ ansats och en del av en experimentell tvågruppsstudie.Urvalet bestod av 113 individer, 60 kvinnor och 53 män, i åldern 20-65 år som var remitteras till en specialistklinik i parodontologi.
