Abstract: Fire is one of the main factors causing biodiversity losses, its main effect on ecological process in the forests are losses in stocks of biomass, change in hydrological cycle and nutrients, forest fires are growing in their size and frequency. Forest fire frequencies, aspect, phytosociological analysis, and population structure of the forest of the two community managed forest locally called (Community Forests) of Almora district, in Kumaun Central Himalaya were studied. The sites were divided into two different aspects i.e. South West (SW) and North West (NW). Based on the phytosociological analysis of four sites represented two major forest types: Pure oak forest and mixed oak-conifer forest. The total basal cover of trees ranged from 4.44 m2 ha-1 to 46.52m2 ha-1.Total tree densities varied from 160 ind ha-1 to 230ind ha-1. Sapling density varied from 360 ind ha-1 to 610 ind ha-1 and seedling density from 120 ind ha-1 to 530 ind ha-1. Pinus roxburghii was the dominant species in SW aspect and Quercus leucotrichophora in NW aspect. The total tree biomass ranged between 9.47 t ha-1 to 62.54 t ha-1 in all aspect of the forests, and the maximum tree biomass was found in north-western aspect of Dhaili van Panchayat forest (62.54 t ha-1). Fire was a strong agent of reducing the number of seedlings and saplings and the biomass stock as well in the studied forest sites, it was observed that those studied sites where fire frequency was regular (every year) the number of sapling and seedling count was 360 ind ha-1 and 370 ind ha-1 in south-eastern aspect for both study sites respectively, while this number increased to 610 and 530 ind ha-1 for the north-western aspect where fire occurred once in a five year.

ABSTRACT: The study was carried out to assess the microbiological quality of street-vended ready-to-eat bole (roasted plantain) fish (Trachurus trachurus) in Port Harcourt metropolis, Nigeria. Eighteen samples of roasted plantain and fish were obtained from three (3) locations in Port Harcourt and analyzed using standard techniques. Inoculations were done using the spread plate and the Most Probable Number (MPN) techniques. Results showed that the total viable count of the head of the fish ranged from 1.2×106 to 5.08×106 CFU/g and the mid section ranged from 1.0×106 to 2.83×106 CFU/g. The percentage of pathogenic bacteria species isolated from the bole and fish samples were; Staphylococcus aureus (46.0%), Bacillus cereus (30.0%), Escherichia coli (13.3%) and Proteus sp. (10.0%). Four spoilage moulds were also isolated and they included; Aspergillus niger (33.3%), Apergillus flavus (33.3%), Penicillium sp. (16.7%) and Neurospora sp. (16.7%). The microorganisms isolated from the roasted Atlantic Horse Mackerel were most likely to be as a result of cross contamination from improper handling, storage and display, as well as their survival mechanisms during the roasting process. These microorganisms are involved in a number of diseases of public health concern and it is recommended that the relevant Ministries of Health and Environment enforce laws and ensure strict compliance to these laws.

Abstract : Infectious bronchitis is a highly contagious disease and considered as one of the most important and common poultry diseases. Only few amino acids differences in the S1 protein of infectious bronchitis virus(IBV) may result in poor protection, that make the control of IBV more difficult especially in endemic country such as Egypt. Protection provided by prepared live attenuated bivalent IBV vaccine containing H120 and CR88 IBV strains were compared with those provided by monovalent live attenuated H120 and CR88(D88) vaccines. Assessment of protection following challenge against a local nephropathogenic IBV strain, based on virus reisolation from tracheaeand kidneys at 3rd day post challenge (DPC). Serum IBV enzyme linked immunosorbent assay (ELISA) antibodies geometric mean titres (GMTs) were 5921, 3422 and 8838 for IBV-H120 live attenuated, IBV-CR88 live attenuated and bivalent live attenuated IBV-H120 CR88 vaccines, respectively, where the control group was 349 at the 3rd week post vaccination (WPV). Also, these results were confirmed by HI test where the antibody mean titre were 8.80,9.50, and 10.0 at 3rd week post vaccination for CR88, H120,and bivalent H120-CR88,respectively.Our results showed that the combined bivalent IBV-H120 CR88 vaccine was the best protectotype where it gave an excellent immune response at the 3rd day post challenge. The protection % was 100% in both trachea and kidney virus reisolation, while it was (100%, 80%) in IBV-H120 vaccine, (60%, 80%) in IBV-CR88 vaccine for trachea and kidney respectively.

Abstract: Rheumatic heart disease (RHD) is still an important cause of heart failure in developing countries. Although there are a few studies of Brain natriuretic peptide (BNP) levels in patients with mitral stenosis and regurge, to our knowledge, no previous study has systematically assessed the levels of BNP and the factors stimulating BNP secretion in rheumatic heart disease.BNP is a cardiac hormone secreted from the ventricular myocardium as a response to ventricular volume expansion and pressure overload.The objective of this work was to measure the leveles of BNP in patients with rheumatic mitral stenosis and regurge and its clinical and echocardiographic correlation. We studied 45 patients, 15 patients with rheumatic mitral stenosis, 15 rheumatic mitral regurge and 15 healthy subjects as a control group. The results of this study showed that there was statistically significant difference between the BNP plasma level in mitral stenosis and regurge patients, and group control subjects. Also there was positive correlation between the plasma level of BNP and the severity of MVD, left ventricular end systolic dimension, left ventricular end diastolic dimension, left atrial size and that there was reverse significance correlation between the plasma level of BNP and left ventricular ejection fraction, but there was no correlation with the gender of the subjects or the presence or absence of pulmonary hypertension. The conclusion from our results suggested that in rheumatic, chronic MVD, BNP activation is present and biologically active and reflects essentially the hemodynamic, ventricular and atrial consequences. Thus, BNP emerge as a biomarker of severity of MVD consequence.

Abstract: Perovskites belong to one of the largest oxide families. The interesting physical properties and important applications have been widely investigated in this system since the last century. Among the large perovskite family, one of the most important groups is the ferroelectric oxide, which possesses extremely high values of dielectric constant and low dielectric loss, as well as good dielectric tunability. Ferroelectricity has been known since the 1920s and ferroelectricity in perovskite BaTiO3 (BTO) was first discovered in the 1940s. In the present work we have studied the pervoskite nature of BaTiO3 (BTO) with its Crystal structure and phase transition.

Abstract: Widely used gas sensor types in house and workplace are semiconductor type and catalytic type. In general, semiconductor gas sensor has good merits in sensitivity. Semiconductor metal oxide thin films have been extensively used for gas sensors as their conductivity changes due to interactions with gas molecules. Such sensors also offer low cost, easy fabrication and consistent performance with respect to other type of gas sensors. Recently, there is an increasing trend to use specifically engineered structured materials as gas sensing elements. The use of such structured materials such as belts, rods and wires in micro-, meso- or nano-dimensions, offer high surface to volume ratios and unique structural features that are expected to enhance the properties and performance of gas sensors. Such structured oxide based chemical sensors were also found to decrease the device response time due to rapid diffusion of gaseous species into the materials’ micro-, meso- and nano-porosities. In this paper we have discussed regarding the basic principle of metal oxide gas sensor application.
