Effect of High Intensity Interval Training on Antioxidants of Male Physical Education Students

The purpose of this study is to find out the efficiency of high intensity interval training on antioxidants of male physical education students. To achieve the purpose thirty (30) male physical education students were selected from Swami Vivekanand Subharti University, Department of Physical Education, Meerut, Utter Pradesh. These subjects were tested on antioxidants before and after eight weeks of high intensity interval training (HIIT). The mean maximal aerobic speed 4.21 m/s was used as a criterion velocity to set running paces for highintensity interval training. Statistical technique used in the present study was 2×2 ANOVA with repeated measures on last two factors. The result of the study revealed that eight weeks of high intensity interval training resulted in 32.65% of increase in Superoxide dismutase (SOD) (F(1,28) =4.663, p < 0.05) and 8.86% on Glutathione peroxidase (GPx) (F(1,28) = 14.88, p < 0.05). However, 4.92% of reduction is noticed in Catalase (CAT) (F(1,28) = 14.88, p < 0.05). It is concluded that high intensity interval training for eight weeks resulted in significant alterations in antioxidants and which indirectly lowered the lipid peroxidation of male physical education students

Unusual presence of Wormian (sutural) bones in human skulls

Wormian bones are a subset of the small intrasutural bones that lie between the cranial sutures formed by the bones of the skull vault. They are formed due to additional ossification centres in or near sutures. They are usually considered as normal variants and seem to be determined genetically in certain populations. They have been linked with rapid cranial expansion as they appear in great number in hydrocephalic skulls. They are commonly found in the lambdoid suture and fontanelles but are occasionally seen in other sutures especially the coronal, squamosal, and sagittal sutures. We examined 25 dried human skulls with the aim to find out the occurrence and variations of Wormian bones, and surprisingly we found Wormian bones in the coronal, squamosal, and sagittal sutures in 6 skulls. These are uncommon sites of occurrence of sutural bones as reported in the literature. These findings prompted us to report these cases as their presence can lead to confusion in diagnosis in cases of skull fractures. (Folia Morphol 2011; 70, 4: 291–294

Otorhinolaryngological causes of proptosis and their sequelae in an eye clinic in Osogbo, south west Nigeria

This was a one year descriptive-cases-series of proptosis presenting to a tertiary eye clinic between January to December 2011. Socio- demographic data were obtained. Subjects aged between 41/ years to 2 75 years who had proptosis referred from the Otorhinolaryngology clinics were examined. Visual acuities, clinical examination of the anterior and posterior segment of the eye, ocular alignment and systemic examination were done. Otorhinolaringologists' findings, laboratory results, radio diagnostic tests, and previous surgical intervention were noted. The major causes of proptosis were due to malignancy (66%) followed by infections and cystic lesions in equal proportions. Half of the subjects who developed visual impairment had improvement in vision and improved facial symmetry after appropriate treatments were instituted. Cases of strabismus were also corrected. Co- management is here demonstrated to give the best cosmetic and visual outcome.Keywords: Otolaryngological causes, proptosis, visual impairmen

Comparative study of thermal insulation boards from leaf and bark fibres of camel’s foot ( Piliostigma thonningii L.)

Plants and agricultural wastes with high degrees of fibrous content in form of lignocellulose compounds have been identified as main ingredient in composites, making them suitable for manufacturing of insulation boards and panels. Thus, several researches have succeeded in using these plants and agro waste fibres in developing renewable and environmentally friendly thermal insulation products. The aim of this study was to compare the performance of insulation boards made from leave and bark fibres of Pilios tigma thonningii L.in terms of density, water absorption, apparent thermal conductivity, specific heat and thermal diffusivity. The leave and the bark fibres were prepared in form of squared boards of 200 mm x 200 mm and thickness of 20 mm using natural ru bber latex as a binder. The fibre to binder ratio was varied with a composition of 1:1, 1:2, 1:3 and 1:4. The LFB recorded densities between 528.6 kg/m 3 and 538.4 kg/m3 while in the BFB the densities are between 558.3 kg/m3 and 711.8 kg/m3 at various compositions. The Percentage water absorption for the LFB is between 36.51% and 12.03% while the BFB is between 25.02% and 13.23%. Similarly, the apparent thermal conductivity values for LFB are between 0.032096 W/mK and 0.040855 W/mK while that of the BFB are between 0.039439 W/mK and 0.043406 W/mK. The specific heat values of the LFB are between 2901.88 J/kg.K and 3656.48 J/kg.K and that of the BFB are between 2044.46 J/kg.K and 2512.61 J/kg.K while the thermal diffusivity is between 2.05E-8m2/s and 8.07E-9m2/s for the LFB and 1.57E-8m2/s to 2.68E-8m2/s for BFB. The boards recorded thermal properties that are comparable to those of the commercially available products with LFB performing consistently better than the BFB. Key words: Thermal Insulation, Leave fibres, Bark fibres, apparent thermal conductivity, Lignocellulose compounds, Fibrous conten

The use of fuzzy real option valuation method to rank Giga Investment Projects on Iran's natural gas reserves

Giga investments are exposed to numerous systematic and unsystematic (or specific) risks that significantly influence their feasibility and value. In addition to the conventional issues and complexities in evaluating investment projects, factors such as long construction time, high amount of capital required and irreversibility of investment, increase uncertainty of cash flows in these types of projects. As a consequence, decision makers are usually not satisfied with the results of the most popular valuation methodology – discounted cash flow analysis – in valuation of Giga investments. The most promising methodology of valuing flexibility in such investment projects is the real options valuation which quantifies the value of embedded flexibilities through option pricing techniques.In this paper, fuzzy real options valuation techniques are used to rank Giga project proposals faced in Iran's gas industry. To this end, different scenarios of project payoff and future uncertainties are quantified, using fuzzy numbers based on findings from earlier real option valuation methods.Keywords: Giga Investment, Fuzzy Pay Off, Real options valuation, Natural Gas, Ira

Cogeneration Power-Desalting Plants Using Gas Turbine Combined Cycle

The gas-steam turbine combined cycle (GTCC) is the preferred power plant type because of its high efficiency and its use of cheap and clean natural gas as fuel. It is also the preferred type in the Arab Gulf countries where it is used as cogeneration power-desalting plant (CPDP). In this chapter, descriptions and analysis of the GTCC components are presented, namely, the gas turbine cycle (compressor, combustor, gas turbine), heat recovery steam generator, and steam turbine. Combinations of the GTCC with thermally driven desalination units to present CPDP are presented. A parametric study to show the effect of using GTCC on several operating parameters on the CPDP is also presented, as well as cost allocation methods of fuel between the two product utilities (electric power and desalted seawater are also presented)
