Personality and Attitudes of Indian Young Female Workforce: Entrepreneurial Orientation by Education and Regions
Subhash C. Kundu,Sunita Rani
Managing Global Transitions , 2007,
Abstract: This investigation analyzes the impact of region and educational background on entrepreneurial orientation of Indian young female trainees by using four personality descriptors i.e. need for achievement, innovation, personal control, and self-esteem around three attitude components i.e. affect, behavior, and cognition. The findings reflect the highest score of the respondents on the achievement motivation as compared to the other three personality descriptors (innovation, personal control, and self-esteem) and lowest score on the self-esteem dimension. Among attitude components, cognition has emerged as highest. Entrepreneurial orientation score of the sample as a whole is moderately high and female trainees from South India are having an edge over their counterparts from North India. Significant differences are not found between females of different educational backgrounds.
Association of arbuscular mycorrhizal fungi in certain medicinal plants of Apocynaceae and Asclepiadaceae
S. SWARUPA RANI and C. MANOHARACHARY*
Indian Phytopathology , 2012,
Abstract: Thirty one host plants belonging to Apocynaceae and Asclepiadaceae were screened for arbuscular mycorrhizal (AM) fungal association in their rhizosphere soils. All plants which were either medicinal or ornamental were found harbouring AM fungi. 48 fungal species representing Acaulospora, Archaeospora, Entrophospora, Gigaspora, Glomus, Scutellospora and SClerocystis were encountered. Glomus with 28 species was the predominant genus. All the host plants surveyed form new host record for AM fungi in India.
Vitamin D and Musculoskeletal Status in Nova Scotian Women Who Wear Concealing Clothing
Rani C. I. Ojah,Jo M. Welch
Nutrients , 2012, DOI: 10.3390/nu4050399
Abstract: Bone and muscle weakness due to vitamin D deficiency is common among Muslim women who reside in sunny, equatorial countries. The purpose of this study was to determine if living in a northern maritime location additionally disadvantages women who wear concealing clothes. A cross-sectional matched pair design was used to compare women who habitually wore concealing clothing with women who dressed according to western norms. Each premenopausal hijab-wearing woman ( n = 11) was matched by age, height, weight and skin tone with a western-dressed woman. Subjects were tested by hand grip dynamometry to assess muscular strength and by quantitative ultrasound at the calcaneus to assess bone status. Nutritional intake was obtained by 24 h recall. Serum 25-hydroxyvitamin D (s-25(OH)D) status was determined in seven matched pairs. The hijab group had lower s-25(OH)D than women who wore western clothes (40 ± 28 vs. 81 ± 32 nmol/L, p = 0.01). Grip strength in the right hand was lower in the hijab-wearing women ( p = 0.05) but this appeared to be due to less participation in intense exercise. Bone status did not differ between groups ( p = 0.9). Dietary intake of vitamin D was lower in the hijab-wearers (316 ± 353 vs. 601 ± 341 IU/day, p = 0.001). This pilot study suggests that women living in a northern maritime location appear to be at risk for vitamin D insufficiency and therefore should consider taking vitamin D supplements.

Eclética Química , 2010, DOI: 10.1590/S0100-46702010000300003
Abstract: a simple, sensitive and reproducible spectrophotometric method was developed for the determination of sitagliptin phosphate in bulk and in pharmaceutical formulations. the proposed method is based on condensation of the primary amino group of sitagliptin phosphate with acetyl acetone and formaldehyde producing a yellow colored product, which is measured spectrophotometrically at 430nm. the color was stable for about 1 hour. beer's law is obeyed over a concentration range of 5-25 μg/ml. the apparent molar absorptivity and sandell sensitivity values are 1.067 x 104 lmol-1cm-1 and 0.0471 μgcm-2 respectively. all the variables were studied to optimize the reaction conditions. no interference was observed in the presence of common pharmaceutical excipients. the validity of the method was tested by analyzing sitagliptin phosphate in its pharmaceutical preparations. good recoveries were obtained. the developed method was successfully employed for the determination of sitagliptin phosphate in various pharmaceutical preparations.
VISCOELASTIC MODELING OF GROUND RESPONSE TO STRONG SURFACE WAVES
RAJNEESH KAKAR,MONIKA RANI,K. C. GUPTA
International Journal of Engineering Science and Technology , 2013,
Abstract: Since soil dynamic behaviour is nonlinear in nature therefore a nonlinear viscoelastic model for isotropic materials is proposed in this study. This model is a combination of inelasticity and nonlinear damping. In this model, the shear modulus is taken as a function of the excitation level. The viscosity is assumed to vary nonlinearly.The validity of this model is checked for low amplitude ground motion response towards strong seismic waves. This method is imposed into a one dimensional finite element approach for a dry soil. The validation of this model is studied for cyclical loading. This model is based on the principle of nonlinear elasticity and nonlinear viscoelasticity which investigate the ground response to strong surface waves excitation. Finally, finite element method is introduced for numerical calculations. Mathematics Subject Classification: 74S05; 74D10; 74J15; 74J30.
SALT STRESS TOLERANCE AND STRESS PROTEINS IN WHEAT (Tritium Aestivum L.)
R. Johnsi Rani,C. Merlin Rose
International Research Journal of Pharmacy , 2012,
Abstract: One of the unique properties of living organisms is growth. Growth is a complex phenomenon and represents the end result of metabolic pathways bringing about an overall irreversible change. Growth is the final morphological expression of various metabolic activities taking place in the plant. Salt stress influences all these metabolic activities and hence influences growth also. Salt stress is caused by concentrations greater than the required for optimum growth of a typical crop plant. If excessive amounts of salt enter into the plant, salt will eventually rise to toxic levels and reduce the photosynthetic leaf area of the plant that cannot sustain growth. Because of the importance of wheat in Indian Agricultural Economy and in order to understand the processes that give rise to tolerance of salt and to identify the salt stress proteins into salt stress effect on plant growth was studied using different salt solutions like copper sulphate, cadmium chloride and zinc sulphate with different concentrations like 200μM, 150 μM and100 μM.
Nanosuspension technology and its applications in drug delivery
Arunkumar N,Deecaraman M,Rani C
Asian Journal of Pharmaceutics , 2009,
Abstract: Solubility is an essential factor for drug effectiveness, independent of the route of administration. Poorly soluble drugs are often a challenging task for formulators in the industry. Conventional approaches for enhancement of solubility have limited applicability, especially when the drugs are poorly soluble simultaneously in aqueous and in non-aqueous media. Nanosuspension technology can be used to improve the stability as well as the bioavailability of poorly soluble drugs. Nanosuspensions are biphasic systems consisting of pure drug particles dispersed in an aqueous vehicle, stabilized by surfactants. These are simple to prepare and are more advantageous than other approaches. Techniques such as wet milling, high-pressure homogenization, emulsification-solvent evaporation and super critical fluid have been used in the preparation of nanosuspensions. It has the advantage of delivery by various routes, including oral, parenteral, pulmonary and ocular routes. The present article reviews the current methods used to prepare nanosuspensions and their application in drug delivery.
Cost Analysis for a Supplier in an Inflationary Environment with Stock Dependent Demand Rate for Perishable Items
Madhu Jain,G. C. Sharma,Varsha Rani
Advances in Decision Sciences , 2014, DOI: 10.1155/2014/457276
Abstract: The present study is concerned with the cost modeling of an inventory system with perishable multi-items having stock dependent demand rates under an inflationary environment of the market. The concept of permissible delay is taken into account. The study provides the cost analysis of inventory system under the decision criteria of time value of money, inflation, deterioration, and stock dependent demand. Numerical illustrations are derived from the quantitative model to validate the results. The cost of inventory and optimal time are also computed by varying different system parameters. The comparison of these results is facilitated by computing the results with neurofuzzy results. 1. Introduction Inflation is a very common scenario of a dynamic market which affects a common man and the decision makers equally. The term inflation refers to the increment in the rates of the goods. Most of the inventory models, developed so far, did not include the inflation and time value of the money as parameters of the system. But, during the past two decades, a sudden downfall in the market caused highly inflated rates and decision makers felt the need of considering the inflation an integrated part of an inventory model. There are many items which are subject to decay with respect to time. The concept of deterioration has been incorporated by some researchers in different frameworks (cf. [1–3]). The management of inventory emphasizing on time dependent deterioration with salvage value was discussed by Mishra and Shah [4]. Jain et al. [5] considered the concept of deterioration to develop a deterministic production inventory model with time-varying demand. Manna et al. [6] developed an EOQ model for noninstantaneous deteriorating items. The concept of exponential deterioration was considered by Mahata [7] to develop an EPQ-based inventory model. Xiao and Xu [8] discussed a supply chain with deteriorating items for a vendor managed inventory. Wang et al. [9] optimized a seller’s credit period in a supply chain for deteriorating items. Some notable works in the direction of inventory models with time value of money along with inflation are due to Bose et al. [10], Moon and Lee [11], Chang [12]. Singh and Jain [13] developed a model to study the supplier credits in an inflationary environment when reserve money was available. An inventory model by considering the concepts of inflation, deterioration, and permissible delay in the payments was studied by Jain and Chauhan [14]. Sarkar and Moon [15] analyzed an EPQ model by incorporating the effect of inflation for an
Spherical Gravitational Collapse of Anisotropic Radiating Fluid Sphere  [PDF]
B. C. Tewari, Kali Charan, Jyoti Rani
International Journal of Astronomy and Astrophysics (IJAA) , 2016, DOI: 10.4236/ijaa.2016.62013
Abstract: We here present a relativistic model for a spherically symmetric anisotropic fluid to study the various factors of physical and thermal phenomenon during the evolution of a collapsing star dissipating energy in the form of radial heat flow. We also proposed a table of some new parametric class of solutions which will be useful for constructing the new compact star models. The constructed algorithm obeys all the relevant requirements of a realistic model and matched with Vaidya exterior metric over the boundary. At the initial stage the interior solutions represent a static configuration of perfect fluid which then gradually starts evolving into radiating collapse. The apparent luminosity as observed by the distant observer at rest at infinity and the effective surface temperature are zero in remote past at the instant when collapse begins and at the stage when collapsing configuration reaches the horizon of the black hole.
Load Balanced Routing Mechanisms for Mobile Ad Hoc Networks  [PDF]
Amita RANI, Mayank DAVE
Int'l J. of Communications, Network and System Sciences (IJCNS) , 2009, DOI: 10.4236/ijcns.2009.27070
Abstract: Properties of mobile ad hoc networks (MANET) like dynamic topology and decentralized connectivity make routing a challenging task. Moreover, overloaded nodes may deplete their energy in forwarding others pack-ets resulting in unstable network and performance degradation. In this paper we propose load-balancing schemes that distribute the traffic on the basis of three important metrics -residual battery capacity, average interface queue length and hop count along with the associated weight values. It helps to achieve load bal-ancing and to extend the entire network lifetime. Simulation results show that the proposed load-balancing schemes significantly enhance the network performance and outperform one of the most prominent ad hoc routing protocols AODV and previously proposed load balanced ad hoc routing protocols including DLAR and LARA in terms of average delay, packet delivery fraction and jitter.
