Changing Perception of Students toward Hospitality Industry: A Comparative Analysis

Hospitality Management Institutes have seen a tremendous growth in the recent years. More and more students are inclining to pursue hospitality related course from the institutes at national level or at different universities or from private institutes. The popularity of this course among the young aspirants is because of various factors such as, job opportunities, different avenues, popularity of various television program based on cooking skills, parents of students already into hotel business, eligibility criteria, entrepreneurship plans, overseas job opportunities, passion and interest, etc. Whenever a student takes admission to the hospitality course he does think positive about the industry. But by reaching to the final year this positivity turns into the negativity and the student takes a decision either not to join the industry or to pursue something else. Therefore, a study is conducted to understand the difference between the perception of 1st year and final year students studying hospitality courses toward the hospitality industry. A structured questionnaire was designed in which 21 variables were included on the basis of review of the literature. Further, T-test was applied to find out the significant difference between the perceptions of 1st year and final year students. Fifteen variables were found where no significant difference exists between the perception of 1st year and final year students. Six variables were found with a significant difference between the perception of 1st year and final year students. The results show that overall a significant difference is there between the perception of 1st year and final year students and null hypothesis is rejected. The study also reveals the fact that 1st year students do have positive perception toward the industry as compared to the final year students

EFAVIRENZ, A WELL KNOWN ANTIVIRAL DRUG, MIGHT BE A NEW OPTION IN THE TREATMENT OF CANCER

Cancer is a potentially fatal disease, where cells abnormally divide which hurts the tissues. The incidences of cancer are increasing worldwide and become one of the leading causes of death. A numbers of anticancer agents are available in the market or under clinical trials used for its treatment, but unfortunately, none of them is able to treat cancer. Thus, the exploration of novel mechanistic pathways of existing molecules may help to develop more effective anticancer agents. Efavirenz, a well-known non-nucleoside reverse transcriptase inhibitor, used in the highly active antiretroviral therapy (HAART) for the treatment of human immunodeficiency virus (HIV) infected patients with tolerable side effects. Newly emerging data revealed that efavirenz has the potential to induce toxic effects against a wide range of cancer cells by altering various cancer pathways. Thus, this existing antiretroviral drug with already known safety profiles could be rapidly utilized for the treatment of various cancers.Keywords: Efavirenz, Endogenous reverse transcriptase, Apoptosis, Anticance

Medical Schools Ignore the Nature of Consciousness at Great Cost

The essential question of the relationship between consciousness and matter is ignored in medical school curricula, leading to a machine-like view of the human being that contributes to physician burnout and intellectual dissatisfaction. The evidence suggesting that the brain may not be the seat of consciousness is generally ignored to preserve the worldview of the primacy of matter. By investigating new frameworks detailing the nature of consciousness at different levels of hierarchy, we can bring intellectual rigor to a once opaque subject that supports a fundamental reality about our experience: We are human beings, not only human bodies

Sprays are among the very main factors of mixture formation and combustion quality in almost every internal combustion engine. In present study spray penetration depth of various spray models are compared with the variation in injected pressure. The Mahua oil is taken as a biodiesel is the present study and Hiroyasu model can be used for predicting the performance of Mahua biodiesel. Hiroyasu model is found best model among all models studied for high injected pressure. The penetration depth difference of Hiroyasu and Arregle models increased sharply with lapse of time. Keywords: biodiesel; penetration depth; injection pressure; spra

Scalable Dense Non-rigid Structure-from-Motion: A Grassmannian Perspective

This paper addresses the task of dense non-rigid structure-from-motion (NRSfM) using multiple images. State-of-the-art methods to this problem are often hurdled by scalability, expensive computations, and noisy measurements. Further, recent methods to NRSfM usually either assume a small number of sparse feature points or ignore local non-linearities of shape deformations, and thus cannot reliably model complex non-rigid deformations. To address these issues, in this paper, we propose a new approach for dense NRSfM by modeling the problem on a Grassmann manifold. Specifically, we assume the complex non-rigid deformations lie on a union of local linear subspaces both spatially and temporally. This naturally allows for a compact representation of the complex non-rigid deformation over frames. We provide experimental results on several synthetic and real benchmark datasets. The procured results clearly demonstrate that our method, apart from being scalable and more accurate than state-of-the-art methods, is also more robust to noise and generalizes to highly non-linear deformations.Comment: 10 pages, 7 figure, 4 tables.

PHARMACOLOGICAL EVALUATION OF ANTI-HYPERLIPIDAEMIC ACTIVITY OF VACHA CHURNA (ACORUS CALAMUS LINN.) AND MUSTA CHURNA (CYPERUS ROTUNDUS LINN.)

Vacha is identified botanically as Acorus calmus Linn belongs to the family Araceae. In Pharmacological study was carried out on Wistar strain albino rats. The activity of the drug was analyzed under the following groups: Group I - Water control, Group II - Cholesterol control, Group III - Vacha Churna and Group IV - Musta Churna. Parameters like ponderal changes, histopathological study of organs, and biochemical parameters mainly the lipid profile were studied. In present study animals administered with hyperlipidaemic diet have shown increase in body weight in comparison to normal rats, however the observed increase is found to be statistically non-significant. Both the test drugs non-significantly attenuated the body weight, among them the magnitude of decreased bodyweight is more in Vacha treated group. In present study administration of hyperlipidaemic diet did not affect the weight if heart, liver and kidney to significant extent in comparison to normal rats. In test drug treated groups also the weight of these organs not affected to significant extent. Administration of Vacha churna and Musta churna did not affect serum lipid parameters in comparison to cholesterol control rats except on serum HDL cholesterol in which moderate attenuation was observed. The test drugs contrary to the expectation did not significantly lower neither the cholesterol nor the triglyceride level in the serum

A novel mechanical seal design with superior thermal characteristics

A mechanical face seal is an important component of variety of pumps used in chemical, petrochemical and process industry. The primary function of a mechanical seal is to prevent leakage of the process fluid from the pump housing and shaft to the environment. The factors that affect the performance of a mechanical seal to leak are friction, wear and its thermal characteristics. Improving upon the thermal characteristics of a mating ring in a mechanical seal would enhance its performance. Implanting a heat exchanger in the mating ring hold great promise for improving the performance of mechanical seals from the viewpoint of reducing heat at the interface and hence enhance the performance of the mechanical seal. To reveal what affect the implanted heat exchangers can have on the thermal characteristics of different seals, in this thesis, three different designs of mating rings were tested in a test rig and the results were compared to a conventional seal in this thesis. A new design of a mechanical seal with an implanted heat exchanger in its mating ring is reported. The mating ring incorporates an internal channel in which a coolant (either a gas or a liquid) flows to remove heat from the seal face. Prototypes were built and tested in a pump. Results are indicative of effective cooling and improved performance when compared to a conventional seal. A Coating on the mating ring was successfully implemented. A simplified heat transfer analysis using the results of the finite element method is also presented for all the seal designs

Designing a reusable class cluster: a hypertext cluster

This thesis is a contribution to the study of object-oriented software engineering, focusing upon the reuse-approach to build reliable and extendable software. A hypertext system has been developed to study the reuse. The ET++ and MacApp framework class libraries provide standard components that can be re-used to develop application-specific programs. A plug-compatible design is presented in this work; this design approach facilitates building applications that work with frameworks based on similar principles running on different platforms. Hypertext is chosen as an example domain for designing class clusters, while ET++ and MacApp are selected as frameworks. A survey of reuse and hypertext is done at various levels. The hypertext specific classes are designed, keeping the commonalities in mind to provide adequate generalization. These classes are implemented on the ET++ and MacApp frameworks. There are variations in the two implementations, but overall design of the classes remains the same. The design is validated by testing it against the changing requirements of the system and adding new functionality to the system. The effectiveness of the plug-compatible approach is explored

Analysis of Monopile Foundation for Offshore Wind Turbine

Load deformation characteristics of monopile are being analyzed in the project. As monopile is a supporting structure for offshore wind turbines. Due to varying environmental conditions exact prediction of load value is not possible but it is important to analyze the load vs deformation relationships to see the behavior of monopile. Monopile structure is subjected to wave, wind load and vertical load for the analysis wave are taken to sinusoidal in nature. The p-y method indicates that the design code recommended p-y curves overestimate for the case of large diameter monopiles the initial stiffness and underestimate the ultimate bearing capacity. When applying the recommended p-y curves as linear springs in a 2D Winkler beam model, the global response of monopole can be calculated regarding load and applied displacement. It is about response based analysis, in which the failure load is being derived from the model developed in MATLAB. In FEM using Abaqus and PLAXIS 3D lateral deflection of the monopile is being seen to visualize the effect of the static lateral load as well as dynamic lateral load with and without vertical loadings. To compare the analysis methods reliability is being calculated using response surface and first order method and the probability of failure is being calculated

ATMOSPHERIC DENSITY ESTIMATION USING SATELLITE PRECISION ORBIT EPHEMERIDES

The current atmospheric density models are not capable enough to accurately model the atmospheric density, which varies continuously in the upper atmosphere mainly due to the changes in solar and geomagnetic activity. Inaccurate atmospheric modeling results in erroneous density values that are not accurate enough to calculate the drag estimates acting on a satellite, thus leading to errors in the prediction of satellite orbits. This research utilized precision orbit ephemerides (POE) data from satellites in an orbit determination process to make corrections to existing atmospheric models, thus resulting in improved density estimates. The work done in this research made corrections to the Jacchia family atmospheric models and Mass Spectrometer Incoherent Scatter (MSIS) family atmospheric models using POE data from the Ice, Cloud and Land Elevation Satellite (ICESat) and the Terra Synthetic Aperture Radar - X Band (TerraSAR-X) satellite. The POE data obtained from these satellites was used in an orbit determination scheme which performs a sequential filter/smoother process to the measurements and generates corrections to the atmospheric models to estimate density. This research considered several days from the year 2001 to 2008 encompassing all levels of solar and geomagnetic activity. Density and ballistic coefficient half-lives with values of 1.8, 18, and 180 minutes were used in this research to observe the effect of these half-life combinations on density estimates. This research also examined the consistency of densities derived from the accelerometers of the Challenging Mini Satellite Payload (CHAMP) and Gravity Recovery and Climate Experiment (GRACE) satellites by Eric Sutton, from the University of Colorado. The accelerometer densities derived by Sutton were compared with those derived by Sean Bruinsma from CNES, Department of Terrestrial and Planetary Geodesy, France. The Sutton densities proved to be nearly identical to the Bruinsma densities for all the cases considered in this research, thus suggesting that Sutton densities can be used as a substitute for Bruinsma densities in validating the POE density estimates for future work. Density estimates were found using the ICESat and TerraSAR-X POE data by generating corrections to the CIRA-72 and NRLMSISE-00 atmospheric density models. The ICESat and TerraSAR-X POE density estimates obtained were examined and studied by comparing them with the density estimates obtained using CHAMP and GRACE POE data. The trends in how POE density estimates varied for all four satellites were found to be the same or similar. The comparisons were made for different baseline atmospheric density models, different density and ballistic coefficient correlated half-lives, and for varying levels of solar and geomagnetic activity. The comparisons in this research help in understanding the variation of density estimates for various satellites with different altitudes and orbits
