Throughout Africa and particularly in Ghana, there are concerns about malaria infection during pregnancy. This study aimed to investigate factors that influence malaria prevention and control practices among pregnant women residing in Chorkor and Korle-Gonno in Accra, Ghana. One hundred and twenty pregnant women between ages 18-49 were randomly recruited during antenatal sessions at a maternity...

The synthesis and characterisation of several sodium zincate complexes are reported. The all-alkyl monomeric sodium zincate, (PMEDTA)·Na(μ-CH2SiMe3)Zn(t)Bu22, is prepared by combining equimolar quantities of (t)Bu2Zn, (n)BuNa and PMDETA (N,N,N',N'',N''-pentamethyldiethylenetriamine)]. A similar approach was used to prepare and isolate the unusual dimeric zincate [(PMEDTA)·Na(μ-(n)Bu)Zn(t)Bu2]23...

Today, since the contemporary world is changing to meet the needs of various people, the aim should be to provide a condition for areas and buildings in order to respond to the needs of various shapes, its future audience requirements, adaptability, flexibility, versatility, etc. Since the scarcity of environmental resources and ecological crises in the world today cannot justify the demolition...

Salen complexes of the heavy alkaline-earth metals, calcium and strontium, were prepared by the reaction of various salen(t-Bu)H(2) ligands with the metals in ethanol. Six new calcium and strontium compounds, [Ca(salen(t-Bu))(HOEt)(2)(thf)] (1), [Ca(salen(t-Bu))(HOEt)(2)] (2), [Ca(salpen(t-Bu))(HOEt)(3)] (3), [Ca(salophen(t-Bu))(HOEt)(thf)] (4), [Sr(salen(t-Bu))(HOEt)(3)] (5), and [Sr(salophen(...

This paper presents an approach for analyzing security-critical software for vulnerability to bu er overrun attacks. In practice, bu er overruns are a commonly exploited attack against security-critical software systems. Bu er overrun attacks are made possible by aws in designing and implementing software. This paper describes a software analysis tool that dynamically analyzes software source c...

The unpredictable intestinal absorption and erratic bioavailability of oral busulfan (Bu) has limited the drug's use in high-dose pretransplantation conditioning therapy. To standardize drug delivery, we solubilized Bu for parenteral use. This new intravenous (i.v.) Bu formulation was combined with oral Bu and cyclophosphamide (Cy) to evaluate (1) the human acute toxicity of i.v. Bu and its sol...

Gene silencing by RNA interference (RNAi) is a promising approach for gene therapy. However, up to today, it is still a major challenge to find safe and efficient non-viral vectors. Previously, we reported PEI-Bu, a small molecular weight PEI derivative, as an efficient non-viral carrier. However, like many PEI-based polymers, PEI-Bu was too toxic. In order to reduce cytotoxicity while maintain...

During the routing of global interconnects, macro blocks form useful routing regions which allow wires to go through but forbid bu ers to be inserted. They give restrictions on bu er locations. In this paper, we take these bu er location restrictions into consideration and solve the simultaneous maze routing and bu er insertion problem. Given a block placement de ning bu er location restriction...

A potentially useful trianionic ligand for the reduction of dinitrogen catalytically by molybdenum complexes is one in which one of the arms in a [(RNCH(2)CH(2))(3)N](3-) ligand is replaced by a 2-mesitylpyrrolyl-alpha-methyl arm, that is, [(RNCH(2)CH(2))(2)NCH(2)(2-MesitylPyrrolyl)](3-) (R = C(6)F(5), 3,5-Me(2)C(6)H(3), or 3,5-t-Bu(2)C(6)H(3)). Compounds have been prepared that contain the lig...
