alpha toxin derived from clostridium perfringens was used for diagnosis of streptococcus agalactiae (st.agalactiae) by rapid and spot camp tests. the selected cl.perfringens strain was cultured in optimized conditions; the supernatant of culture was concentrated by ultra filter and purified by deae cellulose chromatography. the efficacy of both purified and crude α-toxins were examined by rapid...

Introduction. FIDO is the prototype rover for the Mars 2003 mission, complete with an Athena-like science payload [1]. FIDO will be deployed in April 1999 for a series of tests at Silver Lake, CA [2]. In preparation for these tests, we have examined a suite of rocks collected at the site to anticipate the problems expected in field analyses on available rock surfaces as opposed to surfaces that...

Analysis of advanced displacement in construction progress of tunnel excavation with weak surrounding rock is carried out by numerical method and comparison of model test result. In allusion to the problems of regional landslides and extruded large-deformation seriously impacting the stability of rock mass in construction process of large-section tunnel with weak surrounding rock, the elastic-p...

We present langid.py, an off-the-shelf language identification tool. We discuss the design and implementation of langid.py, and provide an empirical comparison on 5 longdocument datasets, and 2 datasets from the microblog domain. We find that langid.py maintains consistently high accuracy across all domains, making it ideal for end-users that require language identification without wanting to i...

One challenge in spoken language recognition is the availability of training data. In this paper, we propose a virtual example construction method to derive artificial training examples from the existing training data. Using the proposed method, both target virtual examples and non-target virtual examples can be derived from the available training samples. An iterative virtual example selection...

Evidence is emerging that the closely related ROCK1 and ROCK2 serine/threonine kinases support the invasive and metastatic growth of a spectrum of human cancer types. Therefore, inhibitors of ROCK are under preclinical development. However, a key step in their development involves the identification of genetic biomarkers that will predict ROCK inhibitor antitumor activity. One identified mechan...

UNLABELLED The Atraumatic Restorative Treatment (ART) approach was suggested to be a suitable method to treat enamel and dentine carious lesions in patients with disabilities. The use of a restorative glass-ionomer with optimal mechanical properties is, therefore, very important. OBJECTIVE To test the null-hypotheses that no difference in diametral tensile, compressive and flexural strengths ...

clay minerals are considered the most important components of clastic reservoir rock evaluation studies. the shurijeh gas reservoir formation, represented by shaly sandstones of the late jurassic-early cretaceous age, is the main reservoir rock in the eastern kopet-dagh sedimentary basin, ne iran. in this study, x-ray diffraction (xrd), x-ray fluorescence (xrf), scanning electron microscopic (s...
