The Globalization of Indian Hindi Movie Industry = Globalizacija hindujske filmske industrije
Rajesh K. Pillania
Management , 2008,
Abstract: Indian movie industry, notably Bollywood, has come a long way in the last two centuries. All in all, it has been a long story of nearly nine decades, with the early shaky screen images having been turned into a multi-pronged and vast economic empire. Today it is the biggest movie industry in the world in terms of number of films. The industry has produced approximately 27,000 feature films and thousands of documented short films. Having established itself as an industry and being duly recognized as one, the Indian popular cinema has over its course made a lot of progress in almost all areas, such as retail infrastructure, financing, marketing and distribution. With a huge spread of Indian diaspora and the growth of Brand India, it has made inroads in the international market. In fact, in the recent past, the export sales of many Indian movies were higher than the domestic sales. The industry has made progress in all four aspects of globalization, (i.e., goods/services, capital, technology and people). In the future in order to get a big market share and give Hollywood a run for its money, however, the industry needs to put in a lot of money and effort, particularly in the international marketing and distribution.
FORMULATION AND EVALUATION OF BILAYER LIQUISOLID TABLETS OF ATORVASTATIN CALCIUM AND FELODIPINE
K. Rajesh,R. Rajalakshmi
International Research Journal of Pharmacy , 2013,
Abstract: Oral route is one of the most popular routes of drug delivery due to its ease of administration, patient compliance, and flexible design of dosage forms. Though it is a convenient route it provides several challenges to the formulator to design a medication. The objective of this study was to develop and evaluate bilayer liquisolid tablets of Atorvastatin calcium as immediate release layer and Felodipine as sustained release layer, to provide polytherapy through a single tablet. The new mathematical model was used to formulate various liquisolid compacts of Atorvastatin calcium and Felodipine and compared with the direct compression tablets. Fourier Transform Infra Red Spectroscopy (FTIR) and Differential scanning calorimetry (DSC) were performed and there was no significant interaction between drug and excipients. The release rates of prepared liquisolid compacts were higher compared to the directly compressed tablets. Dissolution profiles were carried out by using model independent approach. Felodipine liquisolid tablets follow Zero order as “best fit model”.
On-line Drill Wear State Monitoring by Virtual Instrumentation in Machining of Mild Steel
S. Rajesh,K. Marimuthu
Journal of Applied Sciences , 2012,
Abstract: On-line drill wear state monitoring and effective tool replacement at proper time is an important technique to be developed to realize a fully automated manufacturing system. In this study, the standard data acquisition software LabVIEW (Laboratory Virtual Instrumentation Engineering Workbench), in the application of virtual instrumentation is used to predict the drill wear states. Drilling operations have been performed in mild steel workpiece by High-Speed Steel (HSS) drill bits over a wide range of varying cutting conditions. The effective drill wear models are established based on the relationship between cutting current signals and the varying cutting parameters (cutting speed, feed and drill diameter). The cutting tool status is continuously monitored and the degree of drill wear is displayed as a percentage of the maximum permissible wear. LabVIEW facilitates defective tool replacement at the proper time based on drill wear states in the automated manufacturing environment. The effectiveness and reliability of the method are verified by experimental results.

Abstract: The hydrodistilled essential oil of the roots of Chromolaena odorata (L.) R. M. King & H. Rob. was analysed by gas chromatography equipped with flame ionization detector (GC-FID) and gas chromatography coupled with mass spectrometry (GC/MS). A total of twenty-nine compounds have been identified, accounting 97.6% of the total oil. The main constituents were himachalol (24.2%), 7-isopropyl-1,4-dimethyl-2-azulenol (17.6%), androencecalinol (14.1%), and 2-methoxy-6-(1-methoxy-2-propenyl) naphthalene (5.6%). The essential oil consists mainly of phenyl derivatives (41.6%), followed by oxygenated sesquiterpenes ((26.6%), long-chain hydrocarbons (18.9%), sesquiterpene hydrocarbons (6.8%), oxygenated monoterpenes (2.8%), and monoterpene hydrocarbons (0.9%). This study revealed that the roots of C. odorata produced different chemotypes other than leaves oil. This is the first report on the essential oil composition of the roots of C. odorata. 1. Introduction Chromolaena odorata (L.) R. M. King & H. Rob. (Syn: Eupatorium odoratum L.) (Asteraceae) is a perennial herb and distributed throughout India, tropical Asia, and Mexico [1, 2]. In traditional medicine this plant is used in the treatment of coughs, colds, and skin diseases [3], wound healing, and as a local antiseptic agent [4]. C. odorata is a medicinal plant having diverse pharmacological properties, namely, anti-inflammatory [5, 6], antimicrobial [7, 8], antigonorrhoeal [9], antipyretic, antispasmodic [6], diuretic [10], analgesic [11], and wound healing [12] activities. The chemical compositions of the essential oils of C. odorata that have been reported from different countries [13–20] are summarized in Table 1. The essential oil constituents of the leaves of C. odorata from Benin reported as α-pinene, pregeijerene, geijerene, β-pinene, and germacrene D [13] as the major compounds. In a report from Cameroon and Congo, α-pinene and p-cymene [14], while, from India, pregeijerene, epi-cubebol, cubebol, cis-sabinene hydrate, 10-epi-γ-eudesmol, germacrene-D-4-ol, δ-cadinene, germacrene D, geijerene, cyperene, 10-epi-γ-eudesmol, α-muurolol and khusimone [15] have been identified as the major constituents. The major compounds such as α-pinene, geijerene, and pregeijerene from Ivory Coast [16, 17] and α-pinene, β-pinene, germacrene D, β-copaen-4α-ol, β-caryophyllene, geijerene, pregeijerene [18], α-pinene, cadinene, camphor, limonene, β-caryophyllene and cadinol isomer [8] from Nigeria have been identified. In another report from Thailand, pregeijerene, germacrene D, α-pinene, β-caryophyllene, vestitenone,
On Intuitionistic Fuzzy Filters of Intuitionistic Fuzzy Coframes

Journal of Mathematics , 2013, DOI: 10.1155/2013/793824
Abstract: Frame theory is the study of topology based on its open set lattice, and it was studied extensively by various authors. In this paper, we study quotients of intuitionistic fuzzy filters of an intuitionistic fuzzy coframe. The quotients of intuitionistic fuzzy filters are shown to be filters of the given intuitionistic fuzzy coframe. It is shown that the collection of all intuitionistic fuzzy filters of a coframe and the collection of all intutionistic fuzzy quotient filters of an intuitionistic fuzzy filter are coframes. 1. Introduction Frame theory is topology seen through notions of lattice theory; here one takes the lattice of open sets as the basic notion. The concept of Frames has been studied by many mathematicians including Banaschewski, Dowker, and Johnstone. For details one can refer to [1–3]. In 1965 Zadeh [4] introduced the concept of fuzzy sets as the generalization of ordinary subsets. The concept of ideals of a fuzzy subring was studied by Mordeson and Malik in [5] and Prajapati in [6]. In 1983, Atanassov [7] proposed a generalization of the notion of fuzzy set, known as intuitionistic fuzzy sets. In our earlier paper [8, 9], we introduced the concept of intuitionistic fuzzy frames and intuitionistic fuzzy filters of a frame. In this paper, intuitionistic fuzzy filters of a coframe and intuitionistic fuzzy filters of an intuitionistic fuzzy coframe are studied and examined. Subcoframe of the collection of all intuitionistic fuzzy filters of the coframe is obtained. 2. Preliminaries In this section we will review some fundamental definitions. Definition 1. Let be any set; then for any arbitrary , and . Definition 2 (see [1, 2]). A frame is a complete lattice satisfying the infinite distributive law for any and . Definition 3 (see [1, 2]).

A subset of a coframe closed under arbitrary meets, finite joins and having unit (top) element and zero (bottom) element of the coframe is called a sub coframe of . Definition 5 (see [1, 2]). For any coframe , a subset of is a filter if and ,?? . Definition 6 (see [7]). Let be a nonempty set. An intuitionistic fuzzy set (IFS) of is an object of the form , where and define, respectively, the degree of membership and the degree of nonmembership of the element and , for all .

Role of tyrosine phosphorylation in sperm capacitation / acrosome reaction
Rajesh K Naz, Preeti B Rajesh
Reproductive Biology and Endocrinology , 2004, DOI: 10.1186/1477-7827-2-75
Abstract: The process of fertilization is characterized by a series of complex set of events. It involves a species-specific interaction between egg and sperm activating a chain of events that leads to formation of zygote, fetus and finally a baby. However, before a spermatozoon can fertilize an oocyte, it must undergo a cascade of biochemical and physiological changes that facilitates its binding and penetration into the oocyte [1,2]. This time-dependent acquisition of fertilizing competence has been defined as "Capacitation" [3,4].Capacitation confers upon the spermatozoon an ability to gain hyperactive motility, interact with oocyte zona pellucida (ZP), undergo acrosome reaction and initiate oocyte plasma membrane fusion [1]. Capacitation normally occurs in the female genital tract, however, it can also be achieved in vitro. In fact, most of the information about various aspects of sperm capacitation has emanated from in vitro studies. Sperm cells can be capacitated in vitro by using chemically defined media containing appropriate concentrations of electrolytes, metabolic energy sources, and serum albumin (cholesterol acceptor). Although minor variations exist between these media depending on the mammalian species, most of these media contain bicarbonate, calcium and a macromolecule predominantly serum albumin.Although capacitation of a sperm cell is required before fertilization virtually in every mammalian species studied, the molecular mechanisms and signal transduction pathways involved in this process are not clearly understood. Capacitation involves an increase in membrane fluidity, cholesterol efflux, ion fluxes resulting in alteration of sperm membrane potential, increased tyrosine phosphorylation of proteins, induction of hyperactivation and the acrosome reaction. Protein phosphorylation represents a very important aspect of capacitation. Recently, many advances have been made in the study of phosphorylation of proteins during capacitation, which we will review in
Solution of the Generalized Abel Integral Equation by Using Almost Bernstein Operational Matrix  [PDF]
Sandeep Dixit, Rajesh K. Pandey, Sunil Kumar, Om P. Singh
American Journal of Computational Mathematics (AJCM) , 2011, DOI: 10.4236/ajcm.2011.14026
Abstract: A direct almost Bernstein operational matrix of integration is used to propose a stable algorithm for numerical inversion of the generalized Abel integral equation. The applicability of the earlier proposed methods was restricted to the numerical inversion of a part of the generalized Abel integral equation. The method is quite accurate and stable as illustrated by applying it to intensity data with and without random noise to invert and compare it with the known analytical inverse. Thus it is a good method for applying to experimental intensities distorted by noise.

Mishra, Rajesh K.;Agarwal, Rekha;
Brazilian Journal of Physics , 2008, DOI: 10.1590/S0103-97332008000500007
Abstract: coronal mass ejections are vast structures of plasma and magnetic fields that are expelled from the sun into the heliosphere. this material is detected by remote sensing and in-situ spacecraft observations. the present study deals with the influence of four types of cmes namely asymmetric 'full' halo cmes, partial halo cmes, asymmetric and complex 'full' halo cmes and 'full' halo cmes on cosmic ray neutron monitor intensity. the data of ground based neutron monitor of moscow and cme events observed with instruments onboard and wind spacecraft have been used in the present analysis. the method of superposed epoch (chree) analysis has been used to the arrival times of these cmes. it is noteworthy that the frequency of occurrence of asymmetric 'full' halo cmes is significantly high, whereas frequency of occurrence of asymmetric and complex 'full' halo cmes is low compared to other cmes. significant enhancement in cosmic ray intensity is observed after 4 days of the onset of asymmetric full halo and 6 days after the onset of full halo cmes. the fluctuations in cosmic ray intensity are more prior to the onset of both types of the cmes. however, during partial halo cmes the cosmic ray intensity peaks, 8- 9 days prior to the onset of cmes and depressed 3 days prior to the onset of cmes, whereas in case of asymmetric and complex full cmes, the intensity depressed 2 days prior to the onset of cmes and enhanced 2 days after the onset of cmes. the deviations in cosmic ray intensity are more pronounced in case for asymmetric and complex full halo cmes compared to other cmes.
