Vanadium is considered as an essential trace element in some animals. In human’s classification of vanadium as an essential nutrient is still a topic of debate among various research groups. Nutritionally vanadium is thought to be a cofactor in various enzymatic reactions. Increased levels of insulin in blood (hyperinsulinemia) associated with type-2 diabetes mellitus. Increase intake of fat in...

To the Editor: Mohs micrographic surgery (MMS) for melanoma is controversial because of concerns about accuracy detecting on frozen sections. This study's primary analysis examined sensitivity and specificity using hematoxylin eosin (H&E) melanoma-associated antigen recognized by T cells (MART-1) sections compared with permanent The secondary evaluated whether section specimens can be subsequen...

extended abstract 1. statement of the problem in the era prior to the contemporary arabic literature, long, epic poems, which are considered to be the first sparks of epic poetry, were composed. one of these poems, or maybe the very first one of them, is the long, renowned ode of “ozrie” composed by sheikh kazem al-ozri. the poet owes his fame, to a large extent, to this poem. in terms of liter...

Three years of paired TRMM radar, passive microwave (PM), lightning and NCEP reanalysis data are used to answer the question: “Can we classify a storm as flashing, or not, based only on microphysical and environmental observations?”. Univariate, rule-based threshold models are tested, as well as multivariate linear (discriminant analysis) and multivariate nonlinear (neural network) logistic reg...

There is growing interest from ecological experts to create qualitative models of phenomena for which numerical information is sparse or missing. We present a number of successful models in the field of environmental science, namely, the domain of global warming. The motivation behind the effort is to enrich the DynaLearn interactive learning environment model repository. We first model two of ...

The 2-parameter family of massive variants of Einstein’s gravity (on a Minkowski background) found by Ogievetsky and Polubarinov by excluding lower spins can also be derived using universal coupling. A Dirac-Bergmann constrained dynamics analysis seems not to have been presented for these theories, the Freund-Maheshwari-Schonberg special case, or any other massive gravity beyond the linear leve...
