BACKGROUND Integrated Management of Childhood Illness (IMCI) is regarded as a standard public health approach to lowering child mortality in developing countries. However, little is known about how health workers adhere to the guidelines at the national level in sub-Saharan African countries. METHODS Data from the Service Provision Assessment surveys of Namibia (NA) (survey year: 2009), Kenya...

in this article, we have investigated the role of dimethylamine (dma), tributylamine (tba), triethanoleamine (tea), trishydroxymethylamine (trizma), and hexamethyleneterraamine (hmta), in the formation of zeolitic compounds. the experiments were carried out in acidic and basic media using si/al< 10 and si/a1>10. the structure of the resulting synthetic zeolites were similar to natro davyne, amm...

Partially deuterated Ca3Al2(SiO4)y(OH)12 4y–Al(OH)3 mixtures, prepared by hydration of Ca3Al2O6 (C3A), Ca12Al14O33 (C12A7) and CaAl2O4 (CA) phases in the presence of silica fume, have been characterized by Si and Al magic-angle spinning–nuclear magnetic resonance (MAS–NMR) spectroscopies. NMR spectroscopy was used to characterize anhydrous and fully hydrated samples. In hydrated compounds, Ca3A...

Ke et al. (1) raised old questions about the origins and evolution of modern humans in East Asia. Unfortunately, they have shed no new light on the subject, their study amounting only to a large-scale genotyping of three previously observed Asian Y chromosome alleles (2). The authors provided no explicit statistical tests of any of their conclusions, which in any event are not new (3). Nor did ...

Trauma is the leading cause of death in the industrialized world between the ages of one and 40. A number of risk factors including age and gender have been implicated in this regard. It is therefore not surprising that the majority of trauma victims are young males. Their mortality rate following trauma is not only higher compared to females, but they are also more prone to subsequent sepsis. ...

Aluminum silicide microparticles with oxidized rough surfaces were formed on Si substrates through a spontaneous granulation process of Al films. This microparticle formation was caused by interdiffusion of Al and Si atoms at hypoeutectic temperatures of Al-Si systems, which was driven by compressive stress stored in Al films. The size, density, and the composition of the microparticles could b...
