Brucellosis in small ruminants : a seroprevalence study in peri-urban farming around the region of Dushanbe, Tajikistan

The mountainous Central Asian and former Soviet country Tajikistan is the least advantaged country economically among the former Soviet Union states. Approximately 6.5 % of the land is arable in a country where roughly 80 % of the households typically own small numbers of sheep and goats. Management practices and animal husbandry in the villages such as uncontrolled breeding, mixing of animals on pastures favor Transmission of infectious diseases. Brucellosis is a zoonotic bacterial disease caused by Brucella spp. The disease is endemic in Tajikistan. B.

Fördröjning och bortfall av nätverkskorrektioner : osäkerhetskällor för nätverks-RTK

Network RTK is a real-time technique for accurate positioning with Global Navigation Satellite Systems (GNSS). The technology means the use of correction data from a network of GNSS receivers with known positions (reference stations) to reduce the uncertainty in position for the user´s GNSS receiver (rover). However, this requires that the correction data can be transferred seamlessly to the user in real time. Commonly the corrections are transferred via mobile phones. The Swedish National Land Survey operates a nationwide Network RTK service, where users can receive correction data via GSM or mobile Internet (GPRS).

Design comparison between HiperLAN/2 and IEEE802.11a services

This paper is a study and comparison between the two Wireless LAN (WLAN) standards HiperLAN/2 and IEEE 802.11a. WLANs are used instead or together with ordinary LANs to increase mobility in for example an office. HiperLAN/2 is an European standard developed by ETSI and the IEEEs standard is American. A WLAN-card consists roughly of a Medium Access Control (MAC), Physichal layer (PHY) and an antenna. The antenna is the same for the different standards.

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).

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).

Socialt kapital på arbetsmarknaden - En möjlig väg ut?

People are constantly using there friends in order to ask for a favor or to get hold of some information. This is usually done unconsciously and it is just viewed as everyday life behavior. The function and the use of these links definitely have a value, which means that it can be viewed as a form of capital. But this capital is not caught in the traditional theories of physical capital or human capital; it demands it?s on theorization.

En undersökning av framtidametoder för att säkra förband i produktion

The thesis is an examination of the methods that are appropriate and long-term choice to obtain clamping force and secure screw joints in production. The employer, Scania CV AB, Transmission manufactures axle gears to all trucks produced in Södertälje. One of the most common assembly elements is screw joints, where the clamping force is essential to achieve a secure joint. Current methods to secure the joint is due much of the friction effect and is an indirect method to measure the clamping force. The clampforce accuracy becomes more widely with torque angle control.
