Madurella mycetomatis is the main causative agent of human eumycetoma, a severe debilitating disease endemic in Sudan. It has been suggested that eumycetoma has a soil-borne or thorn prick-mediated origin. For this reason, efforts were undertaken to culture M. mycetomatis from soil samples (n = 43) and thorn collections (n = 35) derived from areas in which it is endemic. However, ribosomal sequ...

The purpose of this study is to explore how student competition using the tit-for-tat strategy could be remedied with a minimum design change in order to support student to collaborate constructively in a computer supportedcollaborative learning system called SWoRD (Scaffolded Writing and Reviewing in the Discipline) [5], a reciprocal peer reviewing of writing system. We identified a factor for...

Modulation of synapses under acute stress is attracting much attention. Exposure to acute stress induces corticosterone (CORT) secretion from the adrenal cortex, resulting in rapid increase of CORT levels in plasma and the hippocampus. We tried to test whether rapid CORT effects involve activation of essential kinases as non-genomic processes. We demonstrated rapid effects (~1 h) of CORT on the...

objective : the major objective of this study was to determine the means and 95% confidence interval of normal 6 years old children's motor-verbal skills. based on the results of this study we could develop a measure to diagnose abnormal motor skills. in addition, in this follow-up study, we compared the first-graders' motor-verbal skills to their own skills one year earlier. method: ...

A path in an edge colored graph is said to be a rainbow path if every edge in this path is colored with the same color. The rainbow connection number of G, denoted by rc(G), is the smallest number of colors needed to color its edges, so that every pair of its vertices is connected by at least one rainbow path. A rainbow u − v geodesic in G is a rainbow path of length d(u, v), where d(u, v) is t...

Sun's announcement of the programming language Java more than anything popularized the notion of mobile code, that is, programs travelling on a heterogeneous network and automatically executes upon arrival at the destination. We describe several classes of mobile code and we extract their common characteristics, where security proves to be one of the major concerns. With these characteristics a...

the number of students who can not complete school programs is a serious problem facing many educational systems in all educational levels . drop oui and repetition are one of the most common matters that many educators and researchers interest to study it. there are many reasons on the retention and non-completion patterns, but it can find rarely a philosophical viewpoint on the problem. the a...
