Abstract: Asymmetric curcumin analogue compound is an anticancer compound synthesized from cullilawan oil with several stages of the process such as; Isolation of safrol from cullilawan oil, safol isomerisation, oxidation, intermediate product synthesis and asymmetric curcumin analog synthesis. The amount of energy used for asymmetric curcumin analog synthesis process gives effect to yield. The purpose of this research is to know the effect of process energy on asymmetric curcumin analogue yield from lawang oil. The results of the study showed that the synthesis of curcumin analogue compounds using microwave method on different energy quantities (8.4kJ, 25.2 kJ, 33.6 kJ, 75 kJ) gives effect to yield. The greater the energy used in the process will lower the yield and the energy that gives the highest yield is 8.4 kJ.

Keywords: Asymmetric curcumin analogues, microwaves method, Energy, cullilawan oil

Abstract: A new chain of Schiff base complexes made up of Cu (II), Co (II), Cd (II),Ni (II), and Mn (II) ions derivatives were obtained by the condensation of 4-dimethyl-aminobenzaldehyde, and 4-aminoantipyrin and some amino acids. The structures of all synthesized complexes were established on the basis of their elemental analysis (UV, FTIR, and 1HNMR). The study of X-ray crystallographic shows that the compound (Z)-4-((4-(dimethylamino)benzylidene)amino)-1,5-dimethyl-2-phenyl-1,2-dihydro-3H-pyrazol-3-one (L5) crystallized in monoclinic system with space group of C2/c and the unit cell dimensions are a= 17.7916, b= 6.8610, c= 29.7199, α =90.000 β =101.326 γ = 90.000., Z = 8 and V = 3557.20 Å3.The antibacterial activity of the complexes are tested against Bacillus subtilis, Bacillus cereus and Pseudomonas aeruginosa.

Abstract: The tomato leafminer, Tuta absoluta (Meyrick), is becoming one of the key pests of tomato in Tanzania; which account for its production loss of up to 80 to 100% if left unchecked.The pest was first introduced in Tanzania in 2014.due to porous nature of our borders and lack of quarantine regulations implementation. Tomato producers in Tanzania have little understanding of leafminers, and hence lack best practices for it control.The pest have developed resistance to dozens of pesticides and therefore the (IPM) strategy that employs bio-chemical, biological, physical and cultural methods is the only best option we had at time. Since its introduction in 2014, there was no any sound action plan being implemented.............

Abstract: The research of the present work was to investigate the removal of methylene blue dyes from aqueous solution by using Acid Activated Glossocardia linearifolia Stem (AGLS) carbon. Generally, dyes are organic compounds used as colouring products in chemical, textile, paper, printing, leather, plastics and various food industries. Contaminated waste water passed out from the industry should be treated. In this study, Glossocardia linearifolia Stem carbon was studied for its potential use as an adsorbent for removal of a cationic dye methylene blue. The various factors affecting adsorption, such as initial dye concentration, contact time, adsorbent dose and effect of temperature, were evaluated..............

Abstract: Sm3+ doped SrBi2-xO4 oxides were prepared by sol - gel method via nitrate citrate route with 'x' values ranging from 0.0, 0.1, 0.2, 0.3, and 0.4 (samples C0 - C4). X-ray powder diffraction analysis reveals the single phase monoclinic structure with the space group of P/2m. Rietveld refinement of unit cell structure shows lowered agreement factors Rp , Rwp and Rexp for all the samples. Average crystallite size was determined by Scherrer's relation in the range of ̴ 36 - 45nm. Magnetic properties of the samples were analyzed by using Vibrating Sample Magnetometer at room temperature which reveals a weak ferromagnetic behaviour for C1 to C4 and diamagnetic behaviour for sample C0. EPR studies recorded at liquid helium temperature.............

Abstract: The influence of seasonal changes on the properties of the water in Merta City, Nagaur, Rajasthan was investigated. Composites samples from different sites of Merta City were collected and assessed for both pre-monsoon and post-monsoon seasons. The values of the various parameters were as follows: pH 7.3 to 8.1 for Pre-monsoon season and 7.0 to 7.7 for Post-monsoon season; conductivity 874 to 9138 mhos/cm for Pre-monsoon season and 786 - 8225 mhos/cm for wet season; total dissolved solids (TDS) 568 to 5940 mg/L for dry season and 511 to 5346 mg/L for Post-monsoon season; Fluoride 0.892 to 2.56 mg/L for Pre-monsoon season and 0.83 to 2.38 mg/L for Post-monsoon season. The values for other parameters were exceeding the BIS permissible limit for drinking water. Therefore, the water is highly contaminated & non potable.

Abstract: TIn this paper, a model/software that can predict insulation failure in a natural gas pipeline transmission system was developed by applying established principles of heat flow and gas dynamics. By using the model/software, one will not only know when insulation failure occurred but the location in the long distance pipeline where it occurs. This will reduce the problems associated with late detection, with its adverse consequences such as hydrate formation and pipeline blockage, and explosion and fire

Abstract: About 17.2 million Kenyans lack access to clean water due to increased population growth, high rate of industrialisation and poor waste management. The situation may worsen if immediate measures are not taken. Lead and cadmium are the main heavy metals in contaminated water and their harmful effects such as lung cancer, mental retardation and nerve disorder cannot be under estimated. Available methods for removing these metal ions from water such as use of activated carbon are very expensive and unaffordable to low income earners. Maize cobs which have minimal use after maize harvesting can be utilised to reduce environmental pollution. The primary aim of this study was to investigate the ability of maize cobs derived products to adsorb both lead (II) and cadmium (II) ions and remove methylene blue and turbidity from contaminated water. Maize cobs charcoal was prepared by heating dry maize cobs in a furnace in limited air. Activation was done by use of 1 M sulphuric acid and heating the mixture in a closed vessel............

Abstract: We realized the highly selective synthesis of 1,4-disubstituted 1,2,3-triazoles starting from a terminal alkyne and arylazides, without the presence of metal catalyst, using the sequence hydroamination/1,3-dipolar cycloaddition reaction. The structure of synthesized products was determined by the usual spectroscopic methods (IR, 1H NMR and 13C NMR). The 1,2,3-triazoles obtained were tested for their antimicrobial properties. Most of them showed a significant antibacterial activity against Pseudomonas aeruginosa,
Citrobacter freundii, Escherichia coli, Staphylococcus aureus, and a fungicidal activity against Aspergillus flavus and Aspergillus ochraceus.

Abstract: The newly developed Agar-SiO2 nanocomposite was prepared by hydrothermal method at room temperature. Such nanocomposites could be promising candidate for biomedical and environmental applications. Structural morphology was characterized using scanning electron microscopy (SEM) and Chemical interactions between SiO2 and Agar were analyzed using Fourier transform infrared spectroscopy equipped with attenuated total reflectance (FTIR-ATR), scanning electron microscopy-energy dispersive X-ray spectrophotometry (SEM-EDS) thermogravimetric analysis (TG) and differential scanning calorimetry (DSC). According to the TEM observation, the average composite granules size was about 60 nm and the embedded SiO2 nanoparticles were uniform with an average diameter of 25 nm.

Abstract: The kinetics of the interaction between Chromium (vi) Oxide and Hydrogen Peroxide were studied. Hydrogen Peroxide is marketed in the form of an aqueous solution and being a limiting reagent in this research, its concentration was first determined by titration with standard solution of Potassium Permanganate (0.02M) before its subsequent utilization. The effect of varying mass of CrO3 on the decomposition of fixed volume of H2O2 was studied by measuring the volume of oxygen evolved and the time taken for the evolution to cease. Similarly, the effect of the decomposition of varying volumes of H2O2 with fixed mass of CrO3 was also studied. At the end of the reaction, the volume of O2 evolved and the time taken for the evolution of O2 were equally recorded. The results of the above decompositions indicated that CrO3 acted as a catalyst. The decomposition of H2O2 catalyzed by CrO3 was found to be a first order reaction..............
