We investigated the production of neutralino pairs via photon-photon collisions in the minimal supersymmetric model(MSSM) at future linear colliders. The numerical analysis of their production rates is carried out in the mSUGRA scenario. The results show that this cross section can reach about 18 femto barn for χ̃1χ̃ 0 2 pair production and 9 femto barn for χ̃2χ̃ 0 2 pair production with our chosen...

Aerial emissions from livestock production continue to be an area of concern for both the potential health and environmental impacts. However, information on gaseous, especially greenhouse gas (GHG) emissions for swine breeding/gestation and farrowing production facilities is meager. A 4300-sow breeding, gestation, and farrowing facility in Iowa was selected for extensive field monitoring. A Mo...

Relativistic coupled cluster theory is used to determine accurate electric field gradients in order to provide a theoretical value for the nuclear quadrupole moment of (139)La. Here we used the diatomic lanthanum monohalides LaF, LaCl, LaBr, and LaI as accurate nuclear quadrupole coupling constants are available from rotational spectroscopy by Rubinoff et al. [J. Mol. Spectrosc. 218, 169 (2003)...

Materials and methods: Oral-fluid and serum samples were collected from one barn on each of three PRRSV-infected finishing sites. Six pens per barn (20 to 30 pigs per pen) were sampled repeatedly, beginning when the pigs entered the facilities (3 weeks of age), and then at 5, 8, 12, and 16 weeks of age. Serum samples were tested using a commercial PRRS ELISA. Both serum and oral-fluid samples w...

A prototype sound monitoring and evaluation system was used to measure the noise level in a medium-sized dairy barn. In addition, distribution of from shelter also modeled order determine how much barn, where only animals, mechanical tools working workers barn were source, affect neighboring operations terms intensity. Considering that intensity fluctuates according activities during day, equal...

Såväl svensk som internationell forskning visar att barn placerats i samhällsvård har sämre skolresultat än andra barn. Däremot är kunskapen om hur deras utbildningskarriärer ser ut över en längre tid begränsad. Med hjälp av femtioårig uppföljning kohort bestående drygt 12 000 personer födda 1953, vilka nästan 8 procent varit placerade före 13 års ålder, vi följt utbildningsvägar hela livsförlo...

The Kerinci Rice Barn is the object of this printmaking. rice barn was chosen as creation because its existence already threatened with extinction. In fact, philosophical value very noble and profound. This printmaking made in a surreal style. concept distortion used to make work more surreal. idea behind use an idiom express oneself through art. stages method are: contemplation, prototype, for...
