A user can pose her information need in form of query represented by Q within any definite collection of documents. The unfortunate thing is that, it is impossible to determine ahead which document fits within the relevance definition as depicted by the query. An approach is such that for every information need, there exists an underlying relevance model R assigning the probabilities P(w|R) to the word occurrence in the sets of relevant documents. This method amongst other derives query-document relevance via techniques which are not flexible enough taking into cognizance the incertitude inherent in the process of information retrieval. This work integrate two models: Fuzzy String matching and Fuzzy ranking models to ameliorate this problem by employing fuzzy techniques instead of hard-line methods based on probability.

The motivation of this work is to identify thermal effects on the structural and contact behaviour of a disc-pad assembly using a finite element approach. The first analysis is performed on the disc-pad model without the presence of thermal properties. Structural performance of the disc-pad model such as deformation and von Mises stress is predicted. Next, thermomechanical analysis is performed on the same disc-pad model with the inclusion of convection, adiabatic and heat flux elements. The prediction results of temperature distribution, deformation, stress and contact pressure are presented. Comparison of the structural performance between the two analyses (mechanical and thermomechanical) is also made. From this study, it can assist brake engineers to choose a suitable analysis in order to critically evaluate structural and contact behaviour of the disc brake assembly.

Radiation protection against short wavelength radiation have beeen studied by using Barium sulfate-Epoxy mixture. The outcome of this research showed a good new information about the ability of barium sulfate-Epoxy mixture to protect the humans and environment against short wavelength rays. There is an easy procedure, low cost and available materials to construct the shielding instead of that high cost shielding. Increasing barium sulfate ratios in barium-epoxy mixture leads to increased gamma ray attenuation with decreasing gamma photon energy. The results of high attenuation of gamma ray is due to the prevent of the ray to transimitted through the mixture. A new procedure for radiation protection are used in the labs and work places, which were used the radioactive materials. Short wavelength radiation causes hazards on health of humans and environment, the measurement of gamma photons transmission through barium-epoxy mixture are investigated. The count of CPS is done by maestro software after applying the mixture on cement block. There were two decay energys of gamma ray emitting at 59.5 keV and 26.3 keV. The scattering of gamma ray was studied at various angles.

Much controversy exists over the clinical significance, need for screening and management of PFO in divers. In this study, we investigated the prevalence of PFO, using transesophageal echocardiography (TEE) as the gold standard diagnostic method, in subjects with at least 20 years of diving experience. We recruited 20 male professional military divers with mean (SD) age of 42.1±2.7 years and without any history of cardiac illness. While imaging both atria using TEE, agitated saline was rapidly injected into a right antecubital venous catheter, during normal respiration and also during Valsalva maneuver. A right to left shunt was diagnosed if micro-bubbles appeared in the left atrium within three cardiac cycles. We detected PFO in 13 (65%) of the participants. TEE revealed 7 small, 4 medium and 2 large shunts in our subjects. Moreover regarding the type of right-to-left shunts we found type I and II in 11 (55%) and 2 (10%) of the subjects, respectively. None of them had clinical or echocardiographic signs which could be related to prolonged increase in the right atrial pressure. However, evidence of mild valvular heart disease and mild left ventricular hypertrophy was found in 4 and 2 subjects, respectively. In conclusion, the high prevalence of PFO in our sample warrants further investigation. Furthermore safety of the current diving practices might need to be reassessed in our country based on the evidence accumulating with respect to diving risk and cardiovascular status.

Cookie making behaviour of two wheat–barley flour blends 70:30 and 50:50 (w/w) was modified by addition of 5% and 10% of white/black chia and white/brown teff wholemeal flour. Barley and chia flour have stronger and positive impact on water, sucrose and sodium carbonate SRC; diminishing of lactic acid SRC was softer after chia incorporation. Increase water absorption resulted into significant weakening of dough during overmixing; all three alternative flour contributed to change into dough viscoelastic properties in terms of decrease in the extensigraph extensibility softer than one in elasticity. Conducted amylograph test is designed for constant flour/water ratio – adding of non-traditional flours was in turn recorded as higher suspension viscosity, corresponding with enhancement levels. Bakery softer bi-/tri-composite dough formed biscuits of higher specific volume as well as spread ratio, with somewhat better impact of both teff flour types. Sensorial scoring revealed out acceptability of all 18 tested recipes including alternative flours; partial shifts were observed in terms of paler colour or soft by-taste characteristic for barley or chia. Principal component analysis distinguished tested samples according to barley content; subgroups were clustered according to chia/teff presence in blends, with higher weight of the addition level than white/black seeds type.

Geological situation on the Kremnica-Šturec deposit are currently well examined. Prognostic mineral resources calculated by the Snowden Mining Industry Consultants, in compliance with the requirements of the JORC Code are as follows: 15.4 Mt of ore with the average metal content of 1.75 g.t-1 of gold and 14.9 g.t-1 of silver in the categories of measured and indicated resources. Additional 9.7 Mt of ore with the average metal content of 0.89 g.t-1 of gold and 5.1 g.t-1 of silver in the category of inferred resources (all the data are for the marginal sample of 0.40 g.t-1 of gold). Preliminary study is elaborated on the basis of these prognostic mineral resources (Ortac Resources Ltd). \nAt present, the deposit development, preparation and mining is being considered and the excavation of the reserved deposit using the underground mining method is being prepared for the purpose of excavation of ores containing Au and Ag.

Ezetimibe belongs to a new class of lipid-lowering agents that selectivity inhibits the intestinal absorption of cholesterol and related plant sterols. Due to very low solubility in the aqueous media ezetimibe shows low bioavailability. The aim of the present study investigation was to develop a Lipid Based Formulation (LBF) to enhance the dissolution as well as the oral bioavailability of practically water insoluble Ezetimibe. Type I & Type IV LBF formulation was prepared and evaluated. Solubility of the drug in different oils, Surfactant & co-surfactant was determined. On the basis of the solubility of the ezetimibe in the different oil, surfactant & co-surfactant. Type I & Type IV formulation was prepared in Capriyol 90 (83 mg/ml), Capmul MCM C8 (73.7783 mg/ml) & Cremophore RH 40 (260 mg/ml), Cremophore EL (148 mg/ml), Acysol K 140 (327 mg/ml), Acrysol EL 135 (138 mg/ml), combination of various surfactants with PEG 400. Lipid based formulation then further evaluated for its percentage transmittance, robustness to dilution, stability and drug content. The optimized formulation of Ezetimibe loaded in Lipid based formulation shows complete in vitro drug release in 20min while drug shows only 25.5% drug release in 90 min. In Vitro study proved that the potential use of Lipid based formulation improves the dissolution rate of poorly water soluble drug-Ezetimibe.

The inhibition efficiency and adsorption characteristics of Tridax procumbens Linn leaves extract added in varied concentrations to 1M HCl solution in which mild steel coupons were immersed was investigated in this study using the conventional weight loss measurement method. Mass loss, corrosion rate measurement, atomic adsorption spectroscopy (AAS), Fourier transform infra red spectroscopy (FTIR), and scanning electron microscopy; were used for the analysis. The results show that within the selected range of concentration of the extract and corrosion test temperatures, the inhibition efficiency obtained was within the range of 81 and 96 %. The efficiency values were observed to increase with increase in the extract concentration but decreased with increase in temperature (although less than 5 % reduction was observed for all extract concentrations). The inhibitor molecules were noted to be physically adsorbed on the mild steel surface with OH, NH, and CO groups confirmed as the active phytochemical constituents in the extract responsible for the adsorption. The adsorption model fitted perfectly with the Langmuir adsorption isotherm indicating that the extract was strongly adsorbed on the mild steel surface.
