This work deals with the vibrational spectroscopy of Hexafluorobenzene (HFB) by means of quantum chemical calculations. The FTIR and FT-Raman spectra were measured in the condensed state. The fundamental vibrational frequencies and intensity of vibrational bands were evaluated using density functional theory (DFT) with the standard B3LYP / 6-311+G** basis set combinations, and was scaled using various scale factors which yields a good agreement between observed and calculated frequencies. The vibrational spectra were interpreted with the aid of normal coordinate analysis based on scaled quantum mechanical force field. The results of the calculations were applied to simulated infrared and Raman spectra of the title compound, which showed excellent agreement with the observed spectra.

Schiff bases are typically synthesized by the condensation of amines and a carbonyl bearing compounds. Schiff bases are important intermediates for the synthesis of various bioactive compounds.These compounds and their metal complexes are very important as catalysts in various biological systems, polymers, dyes and medicinal and pharmaceutical fields. Furthermore, they are reported to show a variety of biological activities including antibacterial and antifungal activities.

In order to assess the antioxidant activity of the basidiocarp of mushrooms, viz., Boletus edulis, Ganodrema tsugae and Micoporus xanthopus., an invitro investigation was carried out. The result of the study revealed that the enzymatic antioxidants like catalase and peroxidase were recorded maximally in the basidiocarp of the fungus M. xanthopus (34.190 U mg^-1 and 116.53 U mg^-1 enzyme protein) and minimally in G. tsugae and B. edulis (9.602 U mg^-1 and 66.59 U mg?1 enzyme protein). The non-enzymatic antioxidants like ascorbic acid (vitamin C) and tocopherol (vitamin E) were much pronounced in B. edulis basidiocarp (17.15 µg^-1 and 56.13 µg g^-1 ) compared to M. xanthopus and G. tsugae (17.15 µg^-1 and 26.07 µg g^-1 ) respectively.

Phyllanthus niruri L belongs to family Euphorbiaceae is a field weed. Effect of aqueous and ethanolic extract of P.niruri was investigated on in vitro human blood platelet aggregation in terms of PT (prothrombin time) and APTT (activated partial thromboplastin time). In PT activity was observed maximum in aqueous extracts of aerial parts at 1000 µgmL-1, which was 28 times higher than the standard value. Among the plant parts, aerial parts gave better activity than roots. APTT activity was higher in aqueous extract of roots at 750 µgmL-1 and aerial parts at 1000 µgmL-1 that was 10.75 and 9 times higher, respectively over the standard values. The study revealed that P. niruri has potent anti-platelet aggregation properties.

With the digital technology getting inexpensive and popular, there has been a tremendous increase in the volume and availability of audio through cable and Internet such as music on demand. Currently several web sites host audio and provide users with the facility to browse and watch online audio clips. Due to enhancement in technology in the recent years lots of music is available as handy media for various devices. Thus there is an urgent need of analyzing music for storage, indexing and retrieval. In this paper we aimed at classifying music on the basis of their audios. We have identified three audios for this purpose: happy, angry and sad. These cognitive styles have few things in common. Identifying and extracting these features is a challenging problem. On the basis of our observations and literature review we have identified the eight features namely energy, entropy, zero-crossing rate, spectral rolloff, spectral centroid, spectral flux, RMS of signal and MFCC. After extracting features we have used neural network based training for classification. We have used Artificial Neural Content Techniques and neural net tool for this purpose. We have populated a database of 150 songs consisting of 50 songs of each category. In this population 90 songs are used for training set and 60 for testing. The experimental results demonstrate the effectiveness of our classification system. We have obtained an overall accuracy of nearly 75%. The complete system is developed in ARTIFICIAL NEURAL NETWORK of the system.

Ditch cutting samples of organic rich intervals (Nkporo, Mamu, Nsukka and Imo formations) in Anambra basin from Oda River-1 and Anambra River-2 wells were subjected to Total Organic Carbon (TOC) and Rock-eval Pyrolysis analyses to evaluate their organic matter richness, organic matter type and thermal maturity. The samples comprised of shales, siltstones, lignites and claystones. The shales are dark coloured and moderately indurated with carbonaceous silt and dolomite stringers. The siltstones are fine to medium grained and dark grey to brown in colour. The lignites are grey to black coloured, medium grained, moderately hard to brittle and occurred as stringers. The claystones are grey coloured and medium grained. The TOC and Pyrolysis derived S2 results of the samples are 0.98-4.71 wt. % and 0.12-5.39 mg/g, respectively indicating poor to excellent source rocks. Hydrogen Index, Tmax, Genetic potential and measured vitrinite reflectance are 9-114 mg/g, 424 -471oC, 0.13-5.67 mg/g rock, and 0.41-0.88, respectively. Rock-eval data from the two wells indicated predominantly kerogen type IV kerogen with subordinate gas prone kerogen type III organic matter. Mamu Formation samples dominated kerogen type III and were abundant in Anambra River-2 well. Most samples from Anambra River-2 well are thermally mature while fewer samples from Oda River-1 well are thermally mature for hydrocarbon generation. However, majority of kerogen type III in Anambra River-2 well contained inert carbon.

The most significant energy consumers in energy related industries are boilers and other gas-fired systems. Combustion efficiency term commonly used for boilers and other fired systems and the information on either carbon dioxide (CO2) or oxygen (O2) in the exhaust gas can be used. Efficiency increase and pollutant emission control are the most significant projects of the world. In this paper the incomplete combustion process has solved and the effect of excess air to boiler pollution has considered. The concept of equilibrium constant and molar balanceused to find unknown coefficient in combustion products. The conclusion shows there is an optimum for excess air to reduce boiler pollution and increase boiler efficiency. The conclusion also shows to reduce mole fraction of NO, CO2 and CO in a gas fired boiler, the excess must be about 10 percent.

This paper estimated Foster-Greer-Thorbecke (FGT) poverty indices from the generalized burr density function to further justify the wide flexibility and applicability of the function in fitting many life datasets. It computed estimates of the parameters of the selected density and the goodness of fit statistic from the 2010 Harmonized Nigeria Living Standard Survey (HNLSS) dataset conducted by the National Bureau of Statistics (NBS) of Nigeria. The goodness of fit test indicated that the selected density was appropriate and estimates of the indices obtained from the density were approximately close to the ones obtained through the traditional approach.

The research paper seeks to identify challenges of mobile deposit in Ghana. The study used stratified, convenience and purposeful techniques to arrive at the sample size and descriptive statistics for the presentation and analysis of findings. The mobile deposit solution is 24 hours a day 7 days a week service which makes it convenient for clients of First Capital Plus Bank to deposit money anytime anywhere through mobile banking has proven to be very effective means of mobilizing deposit apart from the traditional usual walk in deposit (Banson et al, 2013). The findings shows that mobile deposit as a way of deposit mobilization through mobile banking has some challenges with the major ones being Accessibility to Speed Banking Cards (SBC’s), Network failure, Deposit not credited to clients account, Delay in crediting clients account and Clients going to the bank before some challenges can be resolved. Accessibility to SBC’s is the key challenge among all.
