Stock And Bond Price Dynamics-Evidence From An Emerging Economy

The motivation for this study is that real stock prices are observed to overreact to changes in interest rates. The real stock prices drop when long-term interest rates rise.  It has been observed that bonds and stock prices are typically studied in isolation. The present paper attempts to analyze the dynamic linkages between stock and bond prices in India.   One of the important contributions of this study is that in India, very little/almost no work has been done to understand the dynamics of the stock and bond prices after the recent recession. The present study examined the bivariate causal relationship between stock prices and bond prices.  In the long term; i.e., periods from 2004 to 2007 and 2008 to 2009, there is no causality from stock market to bond market and vice versa. However, it is found that the bond and stock prices had a bivariate causality in the year 2009 and univariate causality in 2010. The results are interesting and support the view that excess volatility causes granger between the stock and bond markets. This can be inferred as a result of recession investors moving to bond markets and after the signs of recovery the investors might be returning to the stock markets.   It is also evident that short-term interest rates have power to forecast short-term stock returns and risk premiums on observation of co-movement between stock and bond prices. This is reiterated by many empirical studies that have shown that the term “structure of nominal interest rates” contains information potentially useful for the conduct of monetary policy

Feeding stimulatory effects of Cyperus rotundus tuber on Cirrhinus mrigala

Traditionally tubers of cyperus (Cyperus rotundus) and its extracts have been used for alluring fish during harvesting in India. An experiment was conducted to evaluate its feeding stimulatory activity and effect on the growth of a commercially important freshwater fish, Cirrhinus mrigala. Three isonitrogenous and isocaloric formulated diets viz. plant ingredient based control and control supplemented with cyperus tuber (CS) at 1% and 5% levels were fed to the fingerlings of mrigal, C. mrigala (2.68+0.20 g) for a period of 45 days. The growth performance and the activity of metabolic enzymes, aspartate aminotransferase (AST) and alanine aminotransferase (ALT), in liver, gill and muscle tissues of mrigal were studied during every 15 days interval. Highest relative growth (72.28%) was obtained in the mrigal fed with the diet containing 5% cyperus (5% CS), while the relative growths were 66.18% and 43.40% for the fish fed with the 1% CS diet and control respectively. The activities of AST and ALT were significantly higher (p<0.01) in both 1% and 5% CS diets as compared to the control in all the tissues studied. Higher aminotransferase activities were observed in the tissues of 5% CS group than in those of 1% CS group throughout the experimental period. The observed higher enzymatic activity was concomitant with the higher growth rate in fish. The results suggested that cyperus tuber supplementation increased feed palatability and growth

Anti Theft Control System Design using Embedded System

Abstract: In modern day vehicles, vehicle anti-theft system is of prime importance. The vehicle anti-theft system presented here consists of multiple layers of protection with one complementing the other, rather than the conventional anti-theft system where a particular system is only being used. The first layer of protection in the system is a Key recognition, based on which the doors are opened. The Key matching is done by utilizing the Minutiae based Key recognition scheme. Also to prevent thieves from breaking the glass and getting inside the vehicle, vibration sensors are used in all the windows with a threshold level to prevent false alarms. Once inside, the vehicle is turned on only with the mechanical keys along with correct key number entry on the combination keypad present, failing to do so for three successive times will result in vehicle getting immobilized by cutting the fuel supply and an alert message is sent to the mobile number of the owner. Further to prevent the seizure of the vehicle, Tyre pressure sensor is also being used which also alerts the owner through a mobile message. The seized vehicle can be tracked using a GPS tracker which is also being attached. The different layers of protection defined are controlled by an ARM 7 based controller acting as the central node. The whole system was tested using a test set up by mimicking the vehicle door, vehicle immobilizer etc. with equivalent motors whereas Key data was received from Matlab based GUI application. The experimental results proved the functionality of the anti-theft system in working environment

Assessment of safety and efficacy of Karallief® Easy ClimbTM, an herbal extract blend for supporting joint health: a double-blind, placebo-controlled, randomized clinical trial

Background: Osteoarthritis is common among the aging population worldwide. The current techniques to manage osteoarthritis focus on relieving pain and slowing the progression of the disease. Herbal or natural supplements have shown promise in achieving both these treatment goals. Two new proprietary herbal extract blends, Karallief® Easy ClimbTM (KEC) and herbal extracts with glucosamine (HEG), are combinations of several natural products shown to be effective in the treatment of knee osteoarthritis. The current study tested the efficacy and safety of KEC and HEG versus a placebo control.Methods: This is a randomized, double-blind and placebo-controlled study. A total of 120 patients were divided into 3 groups and were given KEC, HEG and Placebo in the ratio 1:1:1. Treatment results were assessed using the 30 second chair stand test, WOMAC test, knee flexion test and joint space measurement using X-rays of the knee joint.Results: The study found that the herbal supplements HEG and KEC significantly reduced osteoarthritis-related knee pain and increased joint mobility and were safe to use during 120 days of treatment. Both supplements resulted in an improvement in the 30 second chair stand test results, WOMAC pain scores, knee flexion, and joint space width as measured by X-ray, as compared to the placebo.Conclusions: Natural supplements such as HEG and KEC improve knee osteoarthritis symptoms and can be a safe and effective treatment option for patients with osteoarthritis

Role of an Agro Technique for the Development of Medicinal Plant: Shalparni

Vrikshayurveda a classical science of botanical field, this science deals with growth and development of plants. This science mainly suggests uses of Kunapa jala and Pancha gavya for the high productivity of crops. This concept works around&nbsp;organic farming for effective plant&nbsp;growth. Vrikshayurvedha mentioned Kunapajala as organic liquid manure which is a fermentation product and acts as plant nutrients. There are two types of Kunapajala mainly in practices viz; herbal and non-herbal which is prepared according to the procedures described in Vrikshayurvedha. Considering importance of this we planned a study to investigate role of Vrikshayurvedha concept for the development of medicinal plant; Shalparni. Present study investigated role of Kunapajala in the growth and % yield of plant Shalparni. This study observed that Kunapajala treatment offered best response with respect to root yield and soil physico-chemical parameters. Kunapajala increased plant yield quantitatively as well as qualitatively

Potentially toxic element (PTEs) related health risk assessment from air conditioner filter dust in and around Chennai metropolitan

1078-1088We report the health risk assessment of air conditioner filter dust collected from different parts of Chennai city, Southern India, using geochemistry and magnetic properties as proxy. The particle size analysis indicates dust particles range from 0.5 μm to 955 μm and the dust grains falling in the range between 30 to 40 μm. The XRD results indicate that the dust samples contain magnetite, hematite, goethite, and trace elements. The hazard index (HI) of trace elements for child and adult determined in our study shows the probable risk for elements as: Cr > Pb > Ni > Cu > Zn. The daily exposure for inhalation [carcinogenic and non-carcinogenic LDDinh] and cancer risk for inhalation (CRinh) were showing high risk and health impact for Cr followed by Ni. It is suggested from the study that higher ventilation rate assisted by means of a mechanical system and use of air conditioners with regular cleaning can improve the living conditions in the Metropolitan areas

Cladribine Analogues via O6-(Benzotriazolyl) Derivatives of Guanine Nucleosides

Cladribine, 2-chloro-2′-deoxyadenosine, is a highly efficacious, clinically used nucleoside for the treatment of hairy cell leukemia. It is also being evaluated against other lymphoid malignancies and has been a molecule of interest for well over half a century. In continuation of our interest in the amide bond-activation in purine nucleosides via the use of (benzotriazol-1yl-oxy)tris(dimethylamino)phosphonium hexafluorophosphate, we have evaluated the use of O6-(benzotriazol-1-yl)-2′-deoxyguanosine as a potential precursor to cladribine and its analogues. These compounds, after appropriate deprotection, were assessed for their biological activities, and the data are presented herein. Against hairy cell leukemia (HCL), T-cell lymphoma (TCL) and chronic lymphocytic leukemia (CLL), cladribine was the most active against all. The bromo analogue of cladribine showed comparable activity to the ribose analogue of cladribine against HCL, but was more active against TCL and CLL. The bromo ribose analogue of cladribine showed activity, but was the least active among the C6-NH2-containing compounds. Substitution with alkyl groups at the exocyclic amino group appears detrimental to activity, and only the C6 piperidinyl cladribine analogue demonstrated any activity. Against adenocarcinoma MDA-MB-231 cells, cladribine and its ribose analogue were most active
