Sentiment Analysis in Marathi Language

Sentiment analysis is inevitable in current era. Internet is growing day-by-day. Now-a-days everything is online. We can shop, buy, and sell online. People can give feedbacks / opinions on the internet. Customers can compare among various products by analyzing the product reviews. As more and more people from different age groups and languages are becoming new internet users, we need it in regional languages. Till date most of the work related to sentiment analysis has been done in English language. But when it comes to Indian languages, not much research has done except for few languages. This paper mainly focuses on performing sentiment analysis in one of the Indian languages i.e. Marathi

Formulation and evaluation of thermoreversible mucoadhesive nasal gels of metoclopramide hydrochloride

The prolonged residence of drug formulation in the nasal cavity is of utmost importance for intranasal drug delivery. The objective of the present investigation was to develop a mucoadhesive in situ gel with reduced nasal mucocilliary clearance in order to improve the bioavailability of the antiemetic drug, metoclopramide hydrochloride. The in situ gelation upon contact with nasal mucosa was conferred via the use of the thermogelling Pluronic flake 127 (18%). Mucoadhesion was modulated via the use of hydroxy propyl methyl cellulose (HPMC), sodium carboxy methyl cellulose (Na CMC) and sodium alginate (Na-alginate) whereas drug release was modified by varying concentrations of polyethylene glycol 6000 (PEG 6000). The results revealed that the different mucoadhesives increased the gel viscosity but reduced its sol gel transition temperatures. The increase in viscosity was highest in formulations with Na-alginate and lowest in formulations with HPMC. PEG 6000 significantly decreased mucoadhesive strength of formula containing 0.3% HPMC (776.6 ± 19.55 to 713.6 ± 5.03), 0.2% Na CMC (656 ± 11.13 to 575 ± 9.07) and 0.2% Na-alginate (659 ± 11.13 to 618.3 ± 9.45) whereas the gelation temperature increased by 3 to 4 °C. 100% of drug diffusion was found at four hours for formulation F5, F9, and F12. Formulation F5 showed maximum permeability (0.00949 ± 0.00021 mg.cm/min) than other formulation containing PEG6000. This study concluded the potential use of mucoadhesive in situ nasal gel in terms of ease of administration, accuracy of dosing, prolonged nasal residence and improved nasal bioavailability.Colegio de Farmacéuticos de la Provincia de Buenos Aire

Tensile Strength Measurement for Foundry Sand Brick

Tensile strength is an important concept in engineering, especially in the fields of material science, mechanical engineering and structural Engineering. The tensile strength of a material is the maximum amount of tensile stress that can be applied to it before it ceases to be elastic. If more force is applied the material will become plastic or even break. Passed the elastic limit, the material will not relax to its initial shape after the force is removed. See Hooke's Law and Modulus of elasticity. The tensile strength where the material becomes plastic is called yield tensile strength. This is the point where the deformation (strain) of the material is unrecovered, and the work produced by external forces is not stored as elastic energy but will lead to contraction, cracks and ultimately failure of the construction. Clearly, this is a remarkable point for the engineering properties of the material since here the construction may lose its loading capacity or undergo large deformations. On the stress-strain curve below this point is in between the elastic and the plastic region. The Ultimate Tensile Strength (UTS) of a material is the limit stress at which the material actually breaks, with sudden release of the stored elastic energy. Tensile strength is measured in units of force per unit area. In the SI system, the unit is Newton per square meter (N/m² or Pa - Pascal). The U.S customary unit is pounds per square inch (or PSI)

A Neighbor Coverage-Based Probabilistic Rebroadcast for Reducing Routing Overhead in Mobile Ad Hoc Networks Using Cluster Scheme

Due to high mobility of nodes in mobile ad hoc networks (MANETs), there exist frequent link breakages which lead to frequent path failures and route discoveries. The overhead of a route discovery cannot be neglected. In a route discovery, broadcasting is a fundamental and effective data dissemination mechanism, where a mobile node blindly rebroadcasts the first received route request packets unless it has a route to the destination, and thus it causes the broadcast storm problem. In this paper, we propose a neighbor coverage-based probabilistic rebroadcast protocol for reducing routing overhead in MANETs. In order to effectively exploit the neighbor coverage knowledge, we propose a novel rebroadcast delay to determine the rebroadcast order, and then we can obtain the more accurate additional coverage ratio by sensing neighbor coverage knowledge. We also define a connectivity factor to provide the node density adaptation. By combining the additional coverage ratio and connectivity factor, we set a reasonable rebroadcast probability. Our approach combines the advantages of the neighbor coverage knowledge and the probabilistic mechanism, which can significantly decrease the number of retransmissions so as to reduce the routing overhead, and can also improve the routing performance

Influence of thickness on properties of plasticized oat starch films.

The aim of this study was to investigate the effect of thickness (between 80 and 120 µm) on apparent opacity, water vapor permeability and mechanical properties (tensile and puncture) of oat starch films plasticized with glycerol, sorbitol, glycerol:sorbitol mixture, urea and sucrose. Films were stored under 11, 57, 76 and 90% relative humidity (RH) to study the mechanical properties. It was observed that the higher the thickness, the higher was the opacity values. Films without the plasticizer were more opaque in comparison with the plasticized ones. Glycerol:sorbitol films presented increased elongation with increasing thickness at all RH. Puncture force showed a strong dependence on the film thickness, except for the films plasticized with sucrose. In general, thickness did not affect the water permeability

EFFECT OF LOWER ETHANOL GASOLINE BLENDS ON PERFORMANCE AND EMISSION CHARACTERISTICS OF THE SINGLE CYLINDER SI ENGINE

Alcohols, basically ethanol is considered as a leading alternative fuel for automotive application because of its ability to reduce the air pollution and cost of the fuel. This paper investigates the effect of lower ethanol gasoline blends (up to 20% by volume) on performance and emission characteristics of the single cylinder four stroke SI engine. Tests were carried out for power, torque, fuel consumption and brake mean effective pressure, while exhaust emissions were analyzed for CO, CO2, and HC by using different ethanol gasoline blends on volume basis at wide open throttle and variable engine speed from 4000 to 8000 rpm. Results were compared with the pure gasoline. It showed that as the ethanol content increases the power, torque, fuel consumption, brake mean effective pressure and CO2 emission while reduces HC and CO emission

A Validated RP-HPLC Method for the Determination of Telmisartan In Bulk and Pharmaceutical Dosage Form

A RP-HPLC method has been developed and validated for the estimation of telmisartan in bulk and pharmaceutical dosage form. A RP-HPLC isocratic separation was achieved on C18 column (250.6 mm i.d., 5m) utilizing a mobile phase comprising of methanol and acetonitrile in the ratio of 90: 10(v/v) and the eluents from the column were detected using a variable wavelength detector at 237nm. The proposed method has permitted the quantification of telmisartan in the linearity range of 20-100g/ml and the flow rate was maintained at 1ml/min. The column was maintained at ambient temperature and the complete separation was achieved for telmisartan in an overall analytical run time of approximately 10 minutes. The retention time of telmisartan was found to be 3.3 minutes. The limit of detection and limit of quantification were found to be 2.82 and 8.54 ?g/ml, respectively. The percentage recovery was found to be in between 87.3 to 103.18%. The method was found to be suitable for the routine quality control analysis of telmisartan in bulk drug and formulation. The method was validated as per ICH guidelines
