Risk assessment of exposure to heavy metals in drinking water in Kilimambogo, Kenya

Article in Press

It is very crucial for man to use clean water for drinking, domestic use, agriculture, food production or other purposes, since it has a great impact on health. The concentration levels of Cu, Cd, Mn, Fe, Ni, Pb and Zn in borehole and surface water of Kilimambogo region were measured using the atomic absorption spectrometer (AAS). pH of the water samples was also measured on site using a digital pH standard meter. The...

Ex-vivo transdermal delivery of Annona squamosa entrapped in niosomes by electroporation

Article in Press

Reactive molecules derived from molecular oxygen and free radicals are commonly known as Reactive Oxygen Species (ROS). These molecules have been suggested to produce oxidative stress in cells leading to many pathological problems like diabetes, cancer, inflammation, neurodegenerative disorders, and aging. Antioxidants can remove free radicals from the human body. Therefore, it is of remarkable interest to increase the...

Design of a narrowband pass unequal power divider using double splintered rectangular ring shape coupled lines with swastika shaped metamaterials (SWMTM)

Article in Press

This paper presents the design of a narrowband pass unequal power divider using double splintered rectangular ring shape coupled lines. The substrate material used between the power divider and the ground is of Rogers RT 5880 (lossy) with a relative permittivity of 2.2. The shape used in design makes the power divider more efficient. The device works at 5.9 GHz with the insertion loss of -3.4 dB at one port and -5.02 dB at...

Liquid-liquid extraction of Zr(IV) from sulphuric acid medium using tri-n-octyl amine in kerosene

Article in Press

The extraction behaviour of Zr(IV) with tri-n-octyl amine (TOA) in kerosene has been studied through a novel method solvent extraction. The mechanism of extraction and the species extracted have been identified. Quantitative extraction of Zr(IV) with TOA was achieved in kerosene by changing different parameters such as acid variation, diluent effect, metal concentration variation, extractant variation, effect of chloride...

Electro-generated low-band-gap conjugated polymer based on Benzothidiazole

Article in Press

Poly (4,7-bis(2,3-dihydrothieno[3,4-b][1,4]dioxin-5-yl)-2,1,3-benzothiadiazole) (PBEDT) a novel low – band – gap polymer has been synthesised by electro-polymerisation of a trimer composed of precursors ethylenedioxythiophene combined with 2,1,3-benzothiadiazole. The Ultraviolet–visible (UV-V) is spectrum of the trimer in chloroform solution gave two absorption bands with peaks at 323 nm and another at 482 nm with an onset...

Influence of the Reynolds number on the parietal exchanges of a paraboloidal retention pond full of water in forced convection

Article in Press

In this work, the authors study the influence of the Reynolds number on the heat and mass transfers in an interface air- water of a parabolic pond of retention full of water in forced convection. The free surface of the pond is crossed by a forced warm air. In the water, the vorticity-stream function is adopted. To resolve the equations in the air which are constituted by a mixture dry air and of steam, the hypotheses of...

Solutions of the space-time fractional of some nonlinear systems of partial differential equations by using modified extended direct algebraic method

Article in Press

In this work, we handle the space – time fractional of classical Drinfeld's Sokolov – Wilson system, the fractional (2+1) – dimensional Davey–Stewartson system and the fractional generalized Hirota- Satsuma coupled KdV systemto solve analytically. Firstly, we use fractional traveling wave transformations to convert fractional nonlinear partial differential equations to nonlinear ordinary differential equations. Next,...

The two-variable )-expansion method for solving the nonlinear potential Boussinesq and ZKBBM equations

Article in Press

We apply the two-variable )--expansion method to construct new exact traveling wave solutions with parameters of the nonlinear potential Boussinesq and ZKBBM equations. This method can be thought of as the generalization of the well-known )---expansion method given recently by Wang and co-workers (2008). When the parameters are replaced by special values, the well-known solitary wave solutions of this equation are...
