The existence of a relatively long (ca. 40 yr) satellite imagery archive for examination of potential worldwide forest change motivated an inspection of the relation between forest features observable from higher resolution airborne and satellite imagery and measures of forest biomass, height, and age. Using these data, we inspected the relation between stand age, mean diameter, height, and sta...

BACKGROUND Multiple sclerosis (MS) is a chronic and disabling disorder with considerable social effects and economic sequelae. It is one of the major causes of disability in young adults. OBJECTIVES This study aimed at detecting the prevalence of MS among the population of Al Quseir city. METHODS This study is a part of door-to-door survey of major neurological disorders that was conducted ...

the hyrcanian forests have been highly exploited in recent decades by human impacts. easy access, abundance and variety of valuable forest yields have led to population growth density, creation of new residential areas and deforestation activities. change detection is one of the main methods of management and evaluation of natural resources. we investigated forest changes in southern surroundin...

Ef®cient identi®cation of forest age is useful for forest management and ecological applications. Here we propose a user-assisted method for determining forest age using high spatial resolution remotely sensed imagery. This method requires individual trees to be extracted from imagery and represented as points. We use a local maximum ®lter to generate points that are converted to Voronoi polygo...

professor jean yoyotte, one of the most prominent french egyptologists, holds that perhaps unlike what the egyptians themselves maintain, the fountainhead of everything is not in egypt; yet one has to agree that circa 3000 bc, egypt was indeed much more advanced than its neighboring states. indelible relics, architectural masterpieces, and works of art remaining from that era have reached us th...

Physical and imagined movements show similar behavioral constraints and neurophysiological activation patterns. An inhibition mechanism is thought to suppress overt movement during motor imagery, but it does not effectively suppress autonomic or postural adjustments. Inhibitory processes and postural stability both deteriorate with age. Thus, older people's balance is potentially vulnerable to ...

Group A rotavirus (RVA) acute gastroenteritis (AGE) is a common cause of severe childhood diarrhea. The dominant circulating RVA genotypes in a given region may vary between and within the geographic regions and from year to year. Our cross-sectional study was designed to determine the burden of RVA genotypes among children with AGE admitted to referral Children Hospital at Egypt prior to imple...
