Free chlorine (FC) and free bromine (FB) produced during ozonation treatment of aquarium seawater pose a serious threat to the health of ornamental aquatic animals, but little is known about the concentration levels of these chemicals in aquarium facilities. In this study, a highly selective and sensitive analytical method based on the derivatization of FC and FB to corresponding 4-halo-2,6dime...

How does the use of social networking sites (SNSs) affect social capital offline and online? The increasing popularity of SNSs such as Facebook (FB) implies a significant change in the way we interact with others. In an extensive longitudinal study (N = 311), carried out in Norway between 2008 2010, we examined the relationship between FB use and social capital, with a focus on interpersonal in...

We surveyed households in rural and urban areas of KwaZulu Natal, South Africa, to assess the exposure of the inhabitants to fumonisin B(1) (FB(1)), a mycotoxin produced by Fusarium verticillioides. In southern African regions maize, used as a staple food by the population, is prone to F. verticillioides infection. Furthermore, high levels of FB(1) in maize have been associated with esophageal ...

To ascertain the agronomic value of material resulting from compost-bedded pack (CBP) in dairy barns, a cross-over experiment was designed with eight dry non-pregnant Holstein cows. The study performed two 11-week periods. Bedding materials used were: (1) CBP sawdust (S) and (2) forest biomass (FB). Samples were taken raw bedding across experiment. We conducted an additional preparing piles, on...

There are no accurate data on the diagnostic value of preoperative flexible bronchoscopy (FB) for persistent ground-glass nodule (GGN) of the lung. We evaluated the value of preoperative FB in patients with suspected GGN-type lung cancer. We retrospectively searched a database for subjects who had 'ground-glass opacity', 'non-solid nodule', 'part-solid nodule', or 'sub-solid nodule' on chest co...

The cross sections for the reactions ee → φη, φη, ρη, ρη have been measured using a data sample of 516 fb collected with the Belle detector at the KEKB asymmetric-energy ee collider. The corresponding values of the cross sections are: 1.4± 0.4± 0.1 fb (φη), 5.3± 1.1± 0.4 fb (φη), 3.1± 0.5± 0.1 fb (ρη) and 3.3± 0.6± 0.2 fb (ρη). The energy dependence of the cross sections is presented using Bell...
