Fundamental Insights into Copper-Epoxy Interfaces for High-Frequency Chip-to-Chip Interconnects.

Future processes and materials are needed to enable multichip packages with chip-to-chip (C2C) data rates of 50 GB/s or higher. This presents a fundamental challenge because of the skin effect, which exacerbates signal transmission losses at high frequencies. Our results indicate that smooth copper interconnects with relatively thin cuprous oxides (CuO, Cu) and amine-functional silane adhesion promoters improve interfacial adhesion with epoxy dielectrics by nearly an order of magnitude.

This study aimed to provide national and zonal-level estimates of the causes of under-five death in Nigeria in the 2013-2018 periods.

The willingness of cooperative societies to sponsor house ownership in Akure, Nigeria.

Housing cooperatives are the organizations among others, which have played important roles in meeting the housing needs of people. In Nigeria, housing finance is through the formal and informal institutions; and personal residences accounted between 75 and 90 per cent of household wealth, that represents between 3 and 6 times their annual income. Finance is an important determinant of success and failure of housing ownership.

Impacts of non-oxidative torrefaction conditions on the fuel properties of indigenous biomass (bagasse).

Biomass is considered as the largest renewable energy source in the world. However, some of its inherent properties such as hygroscopicity, lower energy content, low mass density and bio-degradation on storage hinder its extensive application in energy generation processes. Torrefaction, a thermochemical process carried out at 200-300°C in a non-oxidative environment, can address these inherent problems of the biomass.

Predicting the degradation potential of Acid blue 113 by different oxidants using quantum chemical analysis.

In this work, quantum chemical analysis was used to predict the degradation potential of a recalcitrant dye, Acid blue 113, by hydrogen peroxide, ozone, hydroxyl radical and sulfate radical. Geometry optimization and frequency calculations were performed at 'Hartree Fock', 'Becke, 3-parameter, Lee-Yang-Parr' and 'Modified Perdew-Wang exchange combined with PW91 correlation' levels of study using 6-31G* and 6-31G** basis sets. The Fourier Transform-Raman spectra of Acid blue 113 were recorded and a complete analysis on vibrational assignment and fundamental modes of model compound was performed.

Newborn resuscitation practices and paucity of resuscitative devices in Nigeria; a call to action.

Background: Neonatal resuscitation is a method of preventing morbidities & mortality from asphyxia. Up to 85% of facilities in sub-Saharan Africa lack supplies or skilled personnel for neonatal resuscitation. Relative to the place of birth and the skill of the birth attendant, a variety of resuscitative practice are employed to make babies cry instead of helping the baby breathe.

Comparative outcome of overhead and total body phototherapy for treatment of severe neonatal jaundice in Nigeria.

: In Nigeria, neonatal jaundice is commonly treated by overhead phototherapy with neonates lying supine, often with effective exposure of less than one half of the body surface. Total body exposure in phototherapy has been in use for less than 2 years in Nigeria, but is available in only five neonatal centres.: To compare the effectiveness of total body exposure (TBPE) with the conventional partial exposure (COPT) for treatment of hyperbilirubinaemia.

Complete Ectopia Cordis: A Case Report and Literature Review.

Ectopia cordis is a congenital heart exposure defined as complete or partial protrusion of heart through ventral defect in the thoracoabdominal wall alone or with other viscera in cases of pentalogy of Cantrell.
