to investigate the prevalence of cryptosporidium infection in horses, a total of 221 faecal specimenswere collected from 18 villages of urmia, northwestern iran. the samples were studied microscopically bymodified ziehl-neelsen staining. the cryptosporidial infection was found in the collected samples from 11 of18 villages. although the prevalence of the infection was 15.8%, none of the infecte...

This study aimed to investigate the relationship between race horse breed and the frequency of limb injuries through the time of training and racing. The study population consisted of 4042 Thoroughbred and 2553 Arabian horses raced at Warsaw race Track, from 2000 to 2008. Among these horses, 94 Thoroughbreds and 32 Arabians had different limb injuries. Based on the achieved results, it is possi...

This report presents the results and details of a content-based image retrieval project using the Top-surf descriptor. The experimental results are preliminary, however, it shows the capability of deducing objects from parts of the objects or from the objects that are similar. This paper uses a dataset consisting of 1200 images of which 800 images are equally divided into 8 categories, namely a...

Black ash (Fraxinus nigra) is a species used for basketmaking by several Native American Tribes in Eastern North America. In recent years, there has been a decline in availability of quality ‘basket trees’, and the purpose of this study was to determine what site characteristics allow for the growth of appropriate ring widths required for black ash splints used to make baskets. Three ecosystems...

Climate change is expected to increase the extent and severity of wildfires throughout the boreal forest. Historically, black spruce (Picea mariana (Mill.) B.S.P.) forests in interior Alaska have been relatively free of non-native species, but the compounding effects of climate change and an altered fire regime could facilitate the expansion of non-native plants. We tested the effects of wildfi...

change system to measure the net exchange of CO2 at the surfaces of three shady feather moss and three exposed sphagnum moss sites in a black spruce forest during 35 days at the end of the 1995 growing season. Midday gross photosynthesis was 0.5 to 1.0 μmol m s by feather moss and 0.5 to 2.5 μmol m s by sphagnum moss. Photosynthesis by sphagnum moss was reduced by approximately 70% at 0 °C, and...

Cardiac arrhythmias, caused by disorders in the generation and transmission of cardiac impulses, is included among the heart disorders that cause inefficient blood circulation. The most commonly-used method for diagnosing this disorder is electrocardiography. In this study, we aimed to identify and diagnose different types of arrhythmia prevalent among the seemingly-healthy horses of Sanandaj C...
