Abstract: Three parts of Citrus paradisi grown in Nigeria were chosen with the aim of investigating the chemical compositions of the essential oils and their antimalarial effects. Two-dimensional Gas Chromatography coupled to Time of Flight Mass Spectrometry (GC-TOFMS) was used for compositional profiling and an in vitro anti-plasmodial activity against Plasmodium falciparum (CQS) NF54 was used for malarial screening of the oils. Pulverized plant samples were hydrodistilled using all-glass Clevenger-type apparatus to obtain the essential oils. The compositional profile of the stem oil revealed 36 components (93.28 %). A total of 179 compounds totaling 78.11 % were identified in the root oil while 126 components amounting to 90.51 % were detected in the fruit peel oil. The major components of the stem.........

Abstract: The modification of kola-nuttesta with 0.2M sulphuric acid and 39.9%(v/v) formaldehyde was carried out at 500C. The formaldehyde modified kola-nuttesta (FMKT) and unmodified kola-nuttesta (UKT) were characterized by specific gravity, point of zero charge, melting point, solubility and FTIR spectroscopy. The adsorption capacity of the formaldehyde modifiedkola-nuttesta(FMKT)for Cu2+ and Fe2+ ions in aqueous solution at equilibrium conditions and room temperature were: 2.24 mg/g for Cu2+, 1.97 mg/g for Fe2+.The unmodifiedkola-nuttesta(UKT) gave adsorption capacities of 2.05 mg/g for Cu2+ and 2.12 mg/g for Fe2+metal ions. Percentage removal of the metal ions from a single........

Abstract: European member states have to comply with the Directive 2009/30/EC, which mandates the use of biofuels in motor fuels. Bioethanol is one of the possible renewable fuels that can be used. However, in Mediterranean member states with higher climate temperatures during summer, the production of gasoline with bioethanol as an oxygenate blending component will face increased volatility problems. This study examines the impact of ethanol addition (from 0.5 to 10% v/v) on vapor pressure of refinery streams used for gasoline blends and on commercial motor gasoline fuels. The addition of ethanol in small proportions increased the vapor pressure of the final gasolines tested. The change in vapor pressure was measured (expressed) using delta VP – ΔRVP. The ΔRVP was calculated in each........

Abstract: In this work, the characteristics of NaA zeolite membranes for Cr6+, Zn2+, Cd2+, Co2+ and Pb2+ metals removal from synthesized solutions are presented. These Membranes were elaborated on clay (region of Meknas) which were prepared and characterized by XRD, SEM and N2 permeation. Then we study the effects of synthesis parameters such as temperature T and time on the proprieties of the zeolite membranes. The best conditions for prepared membranes are obtained for T= 80°C, t= 24 h. The tests for the removel of heavy metals in particular: Cr6+, Zn2+, Cd2+, Co2+ and Pb2+ on these NaA zeolite membranes, show that Cr( VI) is around 25%, while it reaches 98% for the other metals after 30 min of filtration.

Abstract: Investigation on Density (ρ) and viscosity (η)of various binary solutions of n-propyl acetate and iso- propyl alcohol have been carried out over a temperature range from 305K to 320K from the data obtained; Excess molar volume (VmE) and deviation in viscosities (Δη)were calculated. These data have been interpreted in terms of possible molecular interactions in binary solutions.

Abstract: The crystal chemistry, thermal studies, electrical conductivity of Nd1-xCaxCrO3(0≤ x≤ 0.5) have investigated. The orthorhombic structure of crystalline sample and lattice constant increases with increasing Ca content(x). The conductivity increases with increasing Ca2+ Contents upto x=0.3. The electrical conductivity can be described by the small polaron hopping conductivity mechanism. Calcium doping significantly depresses the chromium vapourization of NdCrO3 Chemical compatibility and thermal stability under condition this cathode material can be considered as intermediate temperature solid oxide fuel cell.

Abstract: The electrochemical degradation of wastewater containing indigo carmine dye was investigated by synthesized Ru/ graphite modified electrode.The kinetics of degradation by graphite and Ru/graphite modified electrode are compared. Indigo carmine is one of the most important textile dye. The wastewater of indigo carmine can be oxidized to Isatine, which is hydrolyzed to antranilic acid, a compound that is toxic to aquatic life. IR and SEMwere observed for synthesized Ru/ graphite modified electrode.The thin film formation of Ru or encapsulated in graphite rod is observed from SEM/EDAX .The effect of concentration of the dye and the current on the kinetics of degradation were studied. The ICE values of different experimental conditions are evaluated. The anodic oxidation by Ru............

Abstract: Groundwater quality of 40 villages of Bhopalgarh Tehsil, Jodhpur district, Rajasthan was analyzed to identify the nature of groundwater. The groundwater samples were collected in clean polyethylene one-liter cans and subjected for analysis in the laboratory. The physico-chemical parameters studied were pH, electrical conductivity, fluoride (F), chloride (Cl), sulphate, nitrate, total dissolved solids (TDS), Ca and Mg hardness and total hardness (TH). The findings revealed that some of the samples contained chemical constituent beyond permissible limits prescribed by Bureau of Indian Standards (BIS), which cause various hazardous effects. In this paper, regional groundwater contamination will broadly refer to the types of groundwater contamination that can be observed at the regional scale. Based on these results, it is recommended that any groundwater source in the study area should be tested before use for its portability and other domestic or industrial uses.
