Antimicrobial and Cytotoxic Activities of Root Extracts of Piper Chaba
Authors: Naz Tarannum , Mosaddik Ashik , Haque M. Ekramul 
Published: January 2009

Â Â Antibacterial and antifungal properties of petroleum ether, chloroform, ethyl acetate and methanol extracts of Piper chaba (Choi) roots were studied by disc diffusion method and these activities were compared with primary standard drugs Kanamycin and Nystatin, respectively. The extracts were found to exhibit promising antibacterial and antifungal properties against Gram-positive, Gram-negative bacteria and fungi. The extracts were also studied for their cytotoxic activities by brine shrimp lethality bioassay, where gallic acid was used as primary standard. It was observed that the petroleum ether extract was potent cytotoxic with the LC50 value of 0.95 Âµg/ml against Artemia salina (L). The essential oils of the petroleum ether extract of Piper chaba roots were analysed by GC/MS. It was observed that most of the compounds were sesquiterpenes, some were long chain fatty acids and some were monoterpenes and alkaloids. Seventeen compounds were identified from the GC/MS analysis.Â Keywords: Piper chaba, antibacterial activity, antifungal activity, cytotoxicity.Â Â© 2009 JSR Publications.

Published: January 2009

BaCaB2BFeB16BOB27B hexaferrite particles were prepared using two different techniques namely (i) reverse micelle and (ii) co-precipitation with and without presence of surfactants (cationic, anionic and nonionic). The precipitate was calcinated at 950ËC for 4 hours and characterized by using various instrumental techniques. The structural studies of the samples were studied by using XRD and SEM. The field dependent magnetic properties of prepared Ba-Ca hexaferrite powder was investigated at room temperature by using vibrating sample magnetometer. It has been observed that the type of surfactant plays a crucial role in deciding the morphology of the particles. There is significant change in crystallite size of the resultant Ba-Ca hexaferrite prepared in presence of anionic surfactant sodium dodecyl sulfate (SDS) and reverse micelle route. The samples prepared in presence of cationic and non ionic surfactants show agglomerated large particles. Magnetic study reveals that the value of anisotropy constant (K) depends on the type of surfactant used. The sample prepared in presence of nonionic surfactant Polyethylene glycol sorbitan monooleate (Tween 80) shows low anisotropy constant (0.26×10P-3P HAP2P/kg) where as the sample prepared in presence of SDS surfactant exhibits high anisotropy constant (3.26×10P-3 PHAP2P/kg) compared to normal sample (0.41 ×10P-3P HAP2P/kg).Keywords: Barium calcium hexaferrite particles; Surfactants; Structural and magnetic properties.© 2009 JSR Publications.

Peroxy Complex and Crossing Point Temperature of Talcher Coals - An Adducer to Assess the Spontaneous Combustibility Character
Authors: Behera P. , Mohanty G. 
Published: January 2009

Spontaneous combustibility character of the Talcher coals has been measured in terms of peroxy complex and crossing point temperature. Coal samples collected from the two horizons i.e. Karharbari Formation and Barakar Formation were separately studied and the values measured for the aforesaid parameters were recorded. It was found that the coals of this coalfield are highly prone to spontaneous combustion but the coals of the Karharbari Formation show less proneness compared to Barakar Formation.

Hourly and daily clearness index and diffuse fraction at a tropical station, Ile‐Ife, Nigeria
Authors: Okogbue E. C. , Adedokun J. A. , Holmgren B. 
Published: January 2009

AbstractDataset consisting of hourly global and diffuse solar radiation measured over the period February 1992 and December 2002 have been utilized to investigate the diurnal and seasonal variations of hourly and daily clearness index together with the diffuse fraction at a tropical station Ile‐Ife (7.5°N, 4.57°E), Nigeria. Statistical analysis (the frequency and cumulative frequency distribution of the hourly and daily clearness index) and subsequent characterization of the sky conditions over the station based on these were also done, and their implications for solar energy utilization in the area discussed.Daytime (11:00–15:00 LST) monthly mean hourly diffuse fraction, M̄d (explained in a separate ‘List of Symbols’ provided, along with other symbols used in this article), have values, which are most of the time less than 0.52, 0.54 and 0.60 respectively for January, February and March in the dry season. However, during the months of July and August (which are typical of the wet season), the values range between 0.61 and 0.85 (being generally greater than 0.65) with the corresponding values of the monthly mean hourly clearness index, M̄T, ranging between 0.23 and 0.45.Statistical analysis of hourly and daily clearness index showed that the local sky conditions at the station were almost devoid of clear skies and overcast skies (clear skies and overcast skies occurred for only about 3.5% and 4.8% of the time respectively). The sky conditions were rather predominantly cloudy (cloudy skies occurred for about 88% of the time) all the year round. Copyright © 2009 Royal Meteorological Society
Visible light photopolymerization of nitro‐stilbenzene photosensitive initiating systems
Authors: Gao Fang , Peng Huayong , Yang Long , Liu Xiaojiao , Wang Jianchao , Hu Nvdan , Xie Ting , Li Hongru , Zhang Shengtao 
Published: January 2009

AbstractIn this paper, we presented four novel visible light photoinitiating systems, which employed nitro‐stilbenzene derivatives as photoinitiators. Visible light photopolymerization of these systems was studied completely. The results showed that the chemical structures of the photoinitiators, photoinduced electron transfer approach, solvent polarity, and monomers played significant effects on the visible light photopolymerization. The electrochemistry of nitro‐stilbenzene was dramatically influenced by the linking benzophenone moiety. The cyclic voltammograms of four photoinitiators were determined and discussed. We further estimated the thermodriving force for electron transfer between nitro‐stilbenzene and benzophenone. Thermal stabilities of new photoinitators were determined by the analysis of differential scanning calorimetry (DSC) and thermogravimetry (TG) in this paper. Copyright © 2009 John Wiley & Sons, Ltd.
