Urban sprawl, or the unplanned and uncontrolled spreading out of built-up areas in Zaria urban area causes problems of congestion, poor urban basic infrastructure delivery and poor urban planning. This paper analyzed the pattern and implications of urban sprawl using GIS and Remote sensing as an improved approach to analyze and explain sprawling beyond the traditional spatial or cartographic ma...

PURPOSE Although specific genes play a role in regional retinal disease, the correlation of regional gene expression in the disease-affected site has not been previously ascertained. Non-human primates are widely used in models of human retinal function and are theorized to have identical (to human) patterns of expression, but no correlation between primate and human regional retinal gene expre...

The sensitivity of global climate with respect to forcing is generally described in terms of the global climate feedback—the global radiative response per degree of global annualmean surface temperature change.While the global climate feedback is often assumed to be constant, its value—diagnosed from global climate models—shows substantial time variation under transient warming. Here a reformul...

Trauma in children has been a concern but given little attention. Lately however, in Oman, it has been widely discussed in light of prevention of road traffic accidents and home accidents. Trauma in children comes only second to acute infection responsible for morbidity in children, with an annual cost of over £200 millions per year in UK.1 However, there are no cost figures from gulf countries...

Hypoxic pulmonary vasoconstriction (HPV) is thought to actively regulate ventilation-perfusion (V̇a/Q̇) matching, reducing perfusion in regions of alveolar hypoxia. We assessed the extent of HPV in the healthy human lung using inhaled nitric oxide (iNO) under inspired oxygen fractions (FiO2 ) of 0.125, 0.21, and 0.30 (a hyperoxic stimulus designed to abolish HPV without the development of atelect...

The local and regional spread of squamous cancer of the head and neck is well described. We report a possible unusual pattern of spread from a primary laryngeal carcinoma, which presented as gastric perforation.

By recurring to Geometric Probability methods it is shown that the coupling constants, αEM , αW , αC , associated with the electromagnetic, weak and strong (color) force are given by the ratios of measures of the sphere S and the Shilov boundaries Q3 =S 2 ×RP , squashed S, respectively, with respect to the Wyler measure ΩWyler[Q4] of the Shilov boundary Q4 =S ×RP 1 of the poly-disc D4 (8 real d...

The measurements of CMB anisotropy have opened up a window for probing the global topology of the universe on length scales comparable to and beyond the Hubble radius. For compact topologies, the two main effects on the CMB are: (1) the breaking of statistical isotropy in characteristic patterns determined by the photon geodesic structure of the manifold and (2) an infrared cutoff in the power ...
