The emergence of antibiotic resistant strains of bacteria has made natural products attract more attention in the medical field. Honey is one such natural product and its medicinal importance has been recorded since ancient times. The in-vitro antibacterial effectiveness of different types of honey (raw and processed) was tested against two species of bacteria; Staphylococcus aureus (Gram-positive) and Escherichia coli (Gram-negative), using the disk diffusion method. Disks impregnated with different concentrations of processed and unprocessed honey were applied to Mueller Hinton agar plates inoculated with the two bacterial species, and the diameters of the zones of inhibitions measured after 24 hours of incubation. Both types of honey showed antibacterial activity against the tested organisms, with the zones of inhibition (ZOI) ranging from 7 mm to 25?mm. S. aureus was more susceptible (maximum zone of inhibition of 25mm) while E. coli was less susceptible (maximum inhibition zone of 17mm). Both raw and processed honey significantly (p < 0.05) inhibited growth of both species of bacteria at a minimum concentration of 40%. The results of this study point to the potential use of honey as an antibacterial agent and therefore a possible alternative therapy against ailments caused by these two bacterial species.

This investigation uses Multi Channel Analyser (MCA) coupled with Gamma Ray Spectroscope (GRS) to investigate some common counting statistics used for radiation measurements of a 137Cs gamma source. Few statistical tests involving 25 and 100 trials for data acceptance were applied to study the stability of counting system. The statistical analysis evaluated count data on on four primary criteria; the Ratio Test, Chauvenet’s Criterion, the Chi-square test, and a control chart. The control chart also reflected almost accurate statistical data except for a minor error during few points of the 25 trial test. Fano factor was also evaluated for both trials to ascertain the measure of reliability and signal to noise ratio of the equipment. The results demonstrated that the counting system was fairly accurate, with a few exceptions. The Ratio Test, Chauvenet’s Criterion, and the Chi-square test each, was passed successfully. After evaluating the statistical data, Poisson distribution was created to better analyze the data.

The present work deals with the study of mechanical properties of epoxy filled with coconut shell powder and egg shell powder. Epoxy with coconut spell powder and egg shell powder composite was prepared with different filler concentration using hand lay-up technique. Specimens were cut according to the ASTM standards for different experiments, such as flexural test, vickers hardness test and water absorption test. It is observed that at 10 wt% of filler content, coconut shell powder gives the best results for Vickers hardness, flexural strength and flexural modulus. In water absorption test 20% C.S.P absorbs more water compared to other samples.

 In this research to estimate of the forming energy of Zn-Ferrite were used of the isothermal reaction by using Avrami equation and Avrami Ozawa for Non-Isothermal reaction in use Flow Injection Synthesis reactor, whether as Isothermal or non-isothermal. According the methods above can be obtainedthe formation energy of Zn-Ferrite. In this research have be done four time isothermal experiments at the temperature 60 0C,70 0C and 80 0C respectively. The sampling of experiment data have be done effectively using pH data logger where both pH and temperature were written in SD card memory automaticallyin form Excel format. As a result the formation enthalpy (?H) 4.2 kcal / mol with entropy (S) 12.6 cal / mol deg and 3:14 density gr / cc,respectively

Present paper ardently deals with the groundwater vulnerability assessment of Bagh River Watershed (WGW-1/B-designated by central ground water board) of Gondia District of Maharashtra State, India. The groundwater vulnerability assessment of the watershed is analyzed according to the guidelines provided by the APHE, ICMR, WHO and BIS10500. The parameters such as pH, EC, TDS, as well as Chloride, Nitrates, and Fluoride pre and post monsoon have been analyzed. Majority of the samples do not comply with EPA, ICMR, BIS and WHO norms for most of the water quality parameters measured. In order to protect groundwater Vulnerability of Bagh River Watershed of Gondia district, various parameters such as the industrial activities in the area, land cover/use data, hydro geological characteristics of upper aquifers, the lithology and nature of the soil zone for the area, and various predominant contaminating sources have been considered.

Generally, all securities are associated with risks. The actual return an investor receives from the securities is related to risks. So it becomes necessary for him to analyze the securities from the view point of their prices, returns and risks. This analysis is useful in understanding the fluctuation of prices of securities and the behavioral pattern of market before one decides to invest in securities. In general short term investors tend to earn more profit in a short period. One of the effective and simple tools used to have an idea for buying and selling of shares to its maximum yielding in 10 days is “Oscillators”. The name itself expresses the oscillating character of price movement from low level to high level. The investor can get the merits of oscillators and be benefited in short term duration. The present study only micro level analysis. Key words: short term, investment, oscillators, securities, investors. Introduction: The word investment has many interpretations as it means different things to different persons. For a person who has lent money to another, it may be an investment for a return. Similarly, if a person purchases shares of a company for the purpose of price appreciation, it is also an investment for him. Investment is a commitment of funds for earning additional income. Security analysis calls for collection of vast information relating to company and market. The market for securities can be regarded as perfect when demand and supply forces determine the prices of securities. Besides the market price, the investors are interested in knowing the intrinsic value of shares. It is the value of net assets available per equity share of the company. It always revolves around the market price. When the intrinsic value is less than the market price, it is advisable to sell the shares. On the other hand, investors intend to buy securities when the intrinsic value of shares held is more than the market price. Thus, the market analysis and estimate of intrinsic value require collection of information from the appropriate sources.

The present paper reports the growth of Urea Thiourea Potassium Sulphate crystal (UTKS) by slow evaporation method at 30 °C. A Single and Powder X-ray diffraction analysis reveals that UTKS crystals belong to orthorhombic structure at various diffracting planes of the grown crystal were identified. In various functional groups of the grown UTKS crystal were identified by FT-IR spectral analysis. Optical transmittance and energy band gap of grown crystal have been measured from UV-Vis studies. Second harmonic generation was investigated to confirm the non-linear optical properties. The thermal behavior has been examined by TG/DTA analysis and the SEM images of the crystal reveal the well formation of the faces of the crystal. Keywords FT-IR, SHG, SEM analysis, Single and Powder XRD, TG/DTA and UV-Vis.

The impact of changing economics on British subsidized theatres, during Margaret Thatcher’s time raises crucial questions about the role of theatre in society and the relationships between the artist and the ruling political party.

Sudanese petrodiesel samples (S1, S2, S3 &S4) were collected from Khartoum refinery in Sudan. Samples were subjected to physicochemical investigation according to the American Society for Testing and Materials (ASTM) Tests include: density, kinematic viscosity, flash point, cloud point, colour, ash content, water content, sulfur content, carbon residue, copper strip corrosion, distillation and calculated cetane number. Results revealed that the physicochemical properties of petrodiesel samples were within the limits assigned by ASTM and Khartoum refinery except the water content for sample S1 was found to be 0.052% wlw. The cetane number was found to be 56.14, 54.72, 57.89 and 56.9 for S1, S2,S3 and S4 respectively, these values were found within recommended values to be used as fuels for diesel engines.
