Primarily, the vibrational spectroscopic signature of 4-chloro-3-(trifluoromethyl)aniline has been studied experimentally by means of FT-IR and FT-Raman techniques. The electron donating and electron withdrawing effects on the structure of aniline and effects of substituent positions on the vibrational spectra of the title molecule in comparison with similar kind of molecules have also been illustrated. The details about hyperconjugative interactions, HOMO-LUMO energy gap, and molecular electrostatic potential (MEP) surface analysis have been predicted with the help of theoretical density functional theory computations.

The purpose of this study was to detect the concentrations of various heavy metals in meat, liver, milk and fodder of buffaloes by using atomic absorption spectroscopy. For this purpose samples were collected from areas of Kasur and Ring road each having three different sites where fields are irrigated with the industrial effluents. During present investigations the level of most heavy metals in meat of buffaloes ranges from Zn 13.9 to 22.5, Co 0.625 to 33.125, Cu 0.15 to 12.8, Cd 0.14 to 20.4, Ni 2.45 to 27.54, Cr 0.242 to 0.406.However the concentration of these metals in liver of buffaloes ranges from Zn 10.81 to 77.43, Co 3.958 to 20.625, Cu 1.52 to 12.88, Cd 11.85 to 26.1, and Ni 1.29 to 23.38, Cr 0.3122 to 0.4061. In milk of buffaloes it ranges from Zn 3.197 to 18.15, Co 3.958 to 166.458, Cu 0.22 to 6.06, Cd 20.4 to 209, Ni 2.54 to 65.04, Cr 0.2653 to 3.844. Similar levels were seen in fodder of buffaloes Zn 13.15 to 25.05, Co 0.208 to 53.125, Cu 0.38 to 10.61, Cd 0.05 to 9, Ni 0.45 to 47.54, and Cr 0.383 to 0.4765. Generally most values of heavy metals have been found higher in milk of buffaloes from areas of Kasur. Detoxication of industrial effluents being used for irrigation purpose is highly recommended.

Bipolar plates (BPs) are a key component of Proton Exchange Membrane (PEM) Fuel Cells with multifunctional character. They uniformly distribute fuel gas and air, conduct electrical current from cell to cell, remove heat from the active area, and prevent leakage of gases and coolant. Bi-Polar Plates also significantly contributes to the volume, weight and cost of Proton Exchange Membrane Fuel Cell stacks. Hence, there are vigorous efforts worldwide to find suitable materials for Bi-Polar Plates. The materials include non-porous graphite, coated metallic sheets, polymer composites, etc. This paper reviews various types of materials, in use and proposed, for Bi-Polar Plates and critically examines their physical and chemical properties.

This study investigated the development of thermo-regulated and eco-friendly bricks for thermo-regulated houses using anthill clay. Anthill Clay samples obtained from two tropical climatic locations were crushed, properly mixed with adequate water and varied proportions of Cement (0 - 20%), and subjected to standard laboratory experiments. The anthill clay samples for chemical composition, particle size distribution using sieve analysis and Atterberg limits tests were drawn before the compounding of the mixture for other tests. Specimens prepared using anthill clay and anthill-cement mix were tested, for physical, mechanical and thermal properties. The results of chemical composition, particle size distribution, atterberg limits and natural moisture content, showed that the Anthill Clay is a fireclay composed of inorganic coarse silt materials with mild plasticity. The chemical composition revealed that the clay contained residual carbon on ignition of 1.2% which is from the organic matter used by the white ants (termites) in compounding the clay, it is also responsible in regulating the amount of heat that enters the anthill. The effects of Cement on the anthill clay were visible on the dry density with an optimum value of 1878 kgm-3 at 10% additive. The Linear shrinkage and water absorption showed an inversely proportional effect to increasing additive amounts with optimum values of 1.86% and 4.22% at 10% additive respectively. The compressive strength increased with a maximum value of 9.04 Nmm-2 at 20% additive and an optimum value of 3.75 Nmm-2 at 10% additive, while the abrasion index decreased with a minimum value of 0.162units at 20% additive. The thermal conductivity had a direct proportional increase with % cement increase in the bricks, with a minimum value of 0.621W/mK at 0% additive with acceptable values at the other additive percentages. Based on the need to develop a thermo-regulated-eco-friendly brick with improved functional properties and thermoregulatory ability, the optimum product was achieved at 10% admixture (Anthill Clay + Cement 10%) which adhered to all recommended standards of the selected properties for clay bricks. The anthill clay does not emit CO2 and hence the control was from the quantity of cement added. This percentage proportion of the additive is suitable for the production of Anthill Clay brick for building thermo-regulated houses and agricultural storage structures, in urban and most especially in rural areas that are capable of withstanding the recent global warming effects in Nigeria and the world.

The devolved system of governance should not instill a change dilemma in the Kenyan people. It is evident that devolution is likely to be met with resistance from leaders and other members. It is also evident that devolution may intensify inequalities among communities in Kenya since some regions have more natural resources endowed than others Devolution may also be a transfer of the evils committed at the central system of government like corruption and misappropriation of funds to devolved systems. Ultimately, leadership should embrace reducing change resistance methodologies of building trust in the people involved in devolution, discuss upcoming changes, avoid threats in initiating change and involves all stakeholders in implementation devolution for successful implementation of the new structure of governance. The national and county levels should embrace optimum utilization of natural and human resource, focused strategy planning, aggressive resource mobilization and financial planning management. In addition each level of government should exercise integrity and respect constitutional, functional status and government institutions at various levels. Finally, different levels of the devolved structure have an obligation to build on their strengths and opportunities while seeking to eliminate weakness found and boldly face their threats.

This paper evaluates the economic impact of projects fund and personnel costs of propagation on operating performance of the country's two main products, namely wheat and canola, between the years 1997-2007, in Parsabad Moghan region. In this study, data is consisting of three sections: descriptive analysis, and regression relations. In regression analysis, "projects’ fund and propagation of personnel costs" is the independent variable; and “wheat yield" as well as "canola yield" are dependent variables which are inserted into two separate equations, respectively. And given the significance of the value of F (P = 0/0000), in both equations, and also with regard to the high amount of R ¬ 2, it can be concluded that propagation credits are the major role in increasing or reducing the performance of these two products. It can also be concluded that the effect of propagation in increasing the wheat is more than canola yield and it is able to explain 91% of the performance of this product. Also, given the amount of R2, the credits in the case of canola is able to explain 71% of the changes in performance of this product.

Cyperus Articulates extract (CA), was investigated as a green corrosion inhibitor for C steel in 0.5 MH2SO4 solution using mass loss, electrochemical frequency modulation (EFM), potentiodynamic polarization, and (EIS)electrochemical impedance spectroscopy techniques. The temperature effect on corrosion behavior with addition of various concentrations was done in the temperature range of 25-45 ºC by weight loss. Polarization diagram given that the investigated extract is a cathodic behavior. The inhibition efficiency was found to rise with increase in the investigated extract concentration and lower with increase in solution temperature. Adsorption of inhibitor on metal surface found obeyed the adsorption isotherm Langmuir’s. The activation and adsorption parameters were measured and illustrated. The data from electrochemical and chemical methods are a good agreement.
