The Impact of Firm Size on Dividend Behaviour: A Study With Reference to Corporate Firms across Industries in India
Azhagaiah Ramachandran,Veeramuthu Packkirisamy
Managing Global Transitions , 2010,
Abstract: The objective of this paper is to examine the association between the Corporate Leverage (CL) and the Dividend Policy (DP) of firms across industries in India in respect of Size of Corporate Firms. The investigation is conducted on a panel sample of 73 firms across industries [Cement, Chemical and Fertilizer, IT, Oil and Gas, Pharmaceutical, Shipping, and Textiles], which listed their shares in National Stock Exchange (NSE) in India for the period 1996–2007. The impacts of Capital Structure (CS) variables (leverage) on DP measures – dividend payout (Net dividend paid/net income) in the presence of some basic fundamental variables are considered to be the determinants of DP, using the Multiple Regression Technique (OLS method). The results of the cross-sectional ols Model for the selected sample firms under various sectors show that there is a significant effect of selected independent variables. Therefore, this study proves that the DP of Small Size, Medium Size, Large Size, and Overall Corporate Firms across industries in India is dependent on the level of debt in CS.

Computer Science , 2013,
Abstract: Attendance Management System (AMS) can be made into smarter way by using face recognition technique, where we use a CCTV camera to be fixed at the entry point of a classroom, which automatically captures the image of the person and checks the observed image with the face database using android enhanced smart phone. It is typically used for two purposes. Firstly, marking attendance for student by comparing the face images produced recently and secondly, recognition of human who are strange to the environment i.e. an unauthorized person For verification of image, a newly emerging trend 3D Face Recognition is used which claims to provide more accuracy in matching the image databases and has an ability to recognize a subject at different view angles.

BMC Complementary and Alternative Medicine , 2006, DOI: 10.1186/1472-6882-6-35
Abstract: Plants were collected from Palni hills of Southern Western Ghats and the ethnobotanical data were gathered from traditional healers who inhabit the study area. The hexane and methanol extracts were obtained by cold percolation method and the antimicrobial activity was found using paper disc diffusion method. All microorganisms were obtained from Christian Medical College, Vellore, Tamil Nadu, India.The results indicated that out of 18 plants, 10 plants exhibited antimicrobial activity against one or more of the tested microorganisms at three different concentrations of 1.25, 2.5 and 5 mg/disc. Among the plants tested, Acalypha fruticosa, Peltophorum pterocarpum, Toddalia asiatica,Cassia auriculata, Punica granatum and Syzygium lineare were most active. The highest antifungal activity was exhibited by methanol extract of Peltophorum pterocarpum and Punica granatum against Candida albicans.This study evaluated the antimicrobial activity of the some ethnomedicinal plants used in folkloric medicine. Compared to hexane extract, methanol extract showed significant activity against tested organisms. This study also showed that Toddalia asiatica, Syzygium lineare, Acalypha fruticosa and Peltophorum pterocarpum could be potential sources of new antimicrobial agents.According to World Health Organization (WHO) more than 80% of the world's population relies on traditional medicine for their primary healthcare needs. Use of herbal medicines in Asia represents a long history of human interactions with the environment. Plants used for traditional medicine contain a wide range of substances that can be used to treat chronic as well as infectious diseases. A vast knowledge of how to use the plants against different illnesses may be expected to have accumulated in areas where the use of plants is still of great importance [1]. The medicinal value of plants lies in some chemical substances that produce a definite physiological action on the human body. The most important of these bio
A Review on IELTS Writing Test, Its Test Results and Inter Rater Reliability

Theory and Practice in Language Studies , 2012, DOI: 10.4304/tpls.2.1.138-143
Abstract: This research paper is based on the Academic Modules of IELTS test. A study is conducted to evaluate the performance of IELTS test takers and to analyze inter rater reliability in evaluating the test. The test is held at a private university and there are 9 participants who are the students of Foundation, Diploma and Degree courses were assessed only on writing component. This test is rated by three different raters to observe inter rater reliability in evaluating the test. The findings show that rating is not reliable and there is less agreement between the raters as different raters awarded different marks for the students. The total accumulated marks are 588 out of maximum 900 marks and the average score of these 9 students are 65.3% and falls under band 6. Since the IELTS test uses holistic marking, the raters find that the scoring rubrics are too vague in defining the qualities of writing. This study proposes analytic scoring system as a better procedure in assessing IELTS test, whereby it uses separate scales to assess different aspects of writing rather than a single score. The inter rater reliability issue can be overcome if test providers are able to furnish grading scales that could clearly equate the total marks achieved by a candidate to an appropriate band. The result and discussion from this study cannot be generalized to all IELTS candidates as there are many limitations in this study such as student preparedness, tester marking experience, time constraint, and reliability of the test and the validity of the marks tabulation method.

Advances in Environmental Sciences , 2012,
Abstract: The results of the present study describe observations about the distribution of the intertidal polychaete Onuphis eremita along sandyshore of Tranquebar coast, southeast India. The samplings were collected from three different water levels during one year. In sandy shores thebeach worms were crowded. The tidal exposure and percentage composition of sediment particles and organic matter were the main factors influencingthe animal abundance. Highest density was 15.66/m2 in low water mark (LWM) in summer and lowest density occurred during monsoon(4/m2) at high water mark (HWM). The larger animals (32.6 cm) were collected at low water mark and smallest animals (9.2 cm) at midwater mark levels. The environmental parameters showed significant variation with respect to the polychaete distribution. In general the lowwater mark level harbored a larger range of size and number of individuals than the mid water mark and high water mark levels. In addition,these worms had got importance in this region due to their use as bait for more common edible fishes like Sea boss, Groupers, Siver Sillago,Snappers, Rabbitfish and other smaller carangids.

Kaushik Gopalan,K. Sairam,R. Nandakrishnan,Veeramuthu Venkatesh
Journal of Artificial Intelligence , 2013,
Abstract: In cosmopolitan expanses, parking of vehicles has become a major problem as it is becoming unproductive. It is also one of the key causes of city traffic congestion. A mechanism is needed to monitor the parking area. Other associated issues such as lighting of large parking lots and tracking availability of parking spots need to be addressed. The proposed study discussed these issues and gave a solution by employing Open Source Gate Initiative (OSGi), a middleware that helps in efficient communication. The parking system discussed here integrates various communication standards such as the SMS features of a standardized mobile, ZigBee enabled proximity sensors and a system meant for storage and processing of the data. The proposed architecture eliminates the hassles of searching empty parking spots and thus can save a lot of time on a daily basis for the general public who own and use a vehicle for commuting. The merits of this study compared with the existing models are emphasized here. This study also highlighted the advantages of using a standardized middleware such as OSGi for the communication between sensors and a system meant for the storage and processing of the obtained data.

Journal of Language Teaching and Research , 2011, DOI: 10.4304/jltr.2.4.934-940
Abstract: It was noted that one of the most distressing challenges faced by the L2 college students was the poor presentation of their journal writing skills. The researcher noticed a prevailing pattern in their journal writing, where most of them were unable to construct proper sentences, making too many grammatical errors and also lacking in vocabulary. These factors have eventually restricted them from expressing their ideas clearly and effectively in their journal writing. Therefore, this study is primarily designed to look at how second language learners have acquired the use of English language through journal writing and how they have improved within a short time frame. The researcher scaffold a number of 3 undergraduate university college students by using several interactive writing techniques and instructions in writing a journal which showed their progress, daily activities and new experiences. The writing errors from the samples of written journals during week 1 were as it was written before and during the scaffolding period. Data were collected and the results of the progression were obtained based on the observation and comparison of written journals on week 1 and 5. The scaffolding technique presented in this study has helped remedy the challenges faced by the target students by further developing their effectiveness in journal writing.

Journal of Agricultural Chemistry and Environment (JACEN) , 2013, DOI: 10.4236/jacen.2013.21004
Abstract: Three anthocyanins (cyanidin 3-diglucoside, cyanidin 3-sambubioside and cyanidin 3-glucoside) together with eleven known alkaloids (lycoricidine, hipppeastrine,O-Demethyllycoramin, lycoricidinol, galanthine, lycorine, lycorenine, lycoramine, galanthamine, homolycorine and pretazettine) were identified in the flower and bulb of Lycoris radiata using high-performance liquid chromatography coupled with UV detection and electrospray ionization mass spectrometry. Anthocyanins play a major role in protecting plant’s DNA from the UV spectrum of sunlight and also in attracting insects for the purpose of pollination. Thus, knowledge on the contents and types of anthocyanins of L. radiata will help to evaluate the adaptive evolution of flowers and provide useful information for the ornamental breeding.

Abstract: Antibacterial and antifungal activities were tested using Disc diffusion method and Minimum Inhibitory Concentration (MIC). Column chromatography was used to isolate compounds from hexane extract. X-ray crystallography technique and GC-MS analysis were used to identify the compoundsAntibacterial and antifungal activities were observed in hexane, chloroform, ethyl acetate and methanol extracts. Hexane extract of C.speciosus showed good activity against tested fungi also. Two sesquiterpenoid compounds were isolated (costunolide and eremanthin) from the hexane extract. Both the compounds did not inhibit the growth of tested bacteria. But, both the compounds inhibited the tested fungi. The compound costunolide showed significant antifungal activity. The MIC values of costunolide were; 62.5 μg/ml against Trichophyton mentagrophytes, 62. μg/ml against T. simii, 31.25 μg/ml against T. rubrum 296, 62.5 μg/ml against T. rubrum 57, 125 μg/ml against Epidermophyton floccosum, 250 μg/ml against Scopulariopsis sp, 250 μg/ml against Aspergillus niger, 125 μg/ml against Curvulari lunata, 250 μg/ml against Magnaporthe grisea.Hexane extract showed promising antibacterial and antifungal activity. The isolated compound costunolide showed good antifungal activity.Infectious diseases caused by bacteria, fungi, viruses and parasites are still a major threat to public health, despite the tremendous progress in human medicine. Their impact is particularly large in developing countries due to the relative unavailability of medicines and the emergence of widespread drug resistance [1]. Medicinal plants have been a source of bioactive compounds to treat many diseases. Traditionally used medicinal plants produce a variety of compounds with known therapeutic properties [2].Costus speciosus (Koen ex.Retz.) Sm. (Costaceae, Family)is widely used in Ayurveda. The plant rhizome is bitter, useful in treating burning sensation, constipation, leprosy, worm infection, skin diseases, fever, asthma, bronc

Abstract: Background Couroupita guianensis Aubl. (Lecythidaceae) is commonly called Ayahuma and the Cannonball tree. It is distributed in the tropical regions of northern South America and Southern Caribbean. It has several medicinal properties. It is used to treat hypertension, tumours, pain, inflammatory processes, cold, stomach ache, skin diseases, malaria, wounds and toothache. Methods The fruits of Couroupita guianensis were extracted with chloroform. Antimicrobial, antimycobacterial and antibiofilm forming activities of the chloroform extract were investigated. Quantitative estimation of Indirubin, one of the major constituent, was identified by HPLC. Results Chloroform extract showed good antimicrobial and antibiofilm forming activities; however it showed low antimycobacterial activity. The zones of inhibition by chloroform extract ranged from 0 to 26 mm. Chloroform extract showed effective antibiofilm activity against Pseudomonas aeruginosa starting from 2 mg/mL BIC, with 52% inhibition of biofilm formation. When the chloroform extract was subjected to HPLC-DAD analysis, along with Indirubin standard, in the same chromatographic conditions, it was found that Indirubin was one of the major compounds in this plant (0.0918% dry weight basis). Conclusions The chloroform extract showed good antimicrobial and antibiofilm properties. Chloroform extract can be evaluated further in drug development programmes.
