A new analysis method is introduced for investigating whether major flares are clustered in certain fixed regions of the Sun in rigidly-rotating coordinate systems. This method is applied to analysis of major flares of solar cycles 19–23. Northern and southern hemispheres are separately analyzed, and it is found that longitude distributions of flares in the two hemispheres are different. Theref...

BACKGROUND Most universities currently practice traditional practical spot tests to evaluate students. However, traditional methods have several disadvantages. Computer-based examination techniques are becoming more popular among medical educators worldwide. Therefore incorporating the computer interface in practical spot testing is a novel concept that may minimize the shortcomings of traditio...

Background: Spot pricing is considered as a significant supplement for building a full-fledged market economy for the Cloud ecosystem. However, it seems that both providers and consumers are still hesitating to enter the Cloud spot market. The relevant academic community also has conflicting opinions about Cloud spot pricing in terms of revenue generation. Aim: This work aims to systematically ...

OBJECTIVES To expand previous G-spot anatomical and histological investigations; to examine the G-spot complex anatomic role in the anterior vaginal wall ballooning bio-mechanisms; and to determine, which division of autonomic nervous system (sympathetic or parasympathetic) dominates at the time of female sudden death. STUDY DESIGN A prospective-descriptive case series anatomical study on ele...

OBJECTIVES Plasma concentrations are frequently used for therapeutic drug monitoring of antiretroviral drugs. Dried blood spot sampling offers a patient-friendly and easy alternative to plasma sampling. However, dried blood spot concentrations are not necessarily equal to plasma concentrations and therefore the objective of this work was to establish the relationship between nevirapine and efav...

Hematoma expansion (HE) occurs in approximately one-third of patients with intracerebral hemorrhage and leads to high rates of mortality and morbidity. Currently, contrast extravasation within hematoma, termed the spot sign on computed tomography angiography (CTA), has been identified as a strong independent predictor of early hematoma expansion. Past studies indicate that the spot sign is a dy...

In Helicobacter pylori the stringent response is mediated solely by spoT. The spoT gene is known to encode (p)ppGpp synthetase activity and is required for H. pylori survival in the stationary phase. However, neither the hydrolase activity of the H. pylori SpoT protein nor the role of SpoT in the regulation of growth during serum starvation and intracellular survival of H. pylori in macrophages...

introduction: to compare the effects of 0.05% sodium fluoride (naf) mouthrinse, gc tooth mousse and gc mi paste plus on white spot formation inhibition. materials and methods: thirty pairs of extracted human premolars were cut in half mesio-distally with a disc. the teeth were coated with nail varnish, except a part of the buccal and/or lingual enamel, which was used as the test area, and then ...

fungal diseases, chocolate spot (botrytis fabae sard) is the most destructive diseases of faba bean and causes considerable dramatic damage losses on faba bean yield worldwide. the levels of resistance to chocolate spot were evaluated in 35 faba bean cultivars and one susceptible check (ilb365) and local check (barkat) at the gorgan agricultural research station during the 2010 and 2011 croppin...
