Molecular taxonomy and genetic diversity analysis of Therea petiveriana L.
Sheeba, T. J., Manu Thomas Mathai, Aneesh Nair and Florida Tilton

The introduction of DNA barcoding has highlighted the expanding use of the mtDNA gene, cytochrome c oxidase I (COI), as a genetic marker for species identification (Dawnay et al., 2007). In the current study, COI gene based barcoding was employed to identify the seven spotted cockroach, Therea petiveriana. The genetic diversity amongst this cockroach collected from various locations in Tamil nadu, India was analysed by the banding patterns obtained in RAPD PCR. This was further validated...

The effect of stabilizers on Electroless copper plating from Saccharose-containing methane Sulphonate baths
BalaRamesh, P., Venkatesh, P. and Rekha, S.

The effect of addition of 2-Mercaptobenzothiazole (2-MBT), Thiourea, N-Methyl thiourea and 2,2’-dipyridyl on electroless copper deposition from a methane sulphonate bath are studied. Saccharose and Para formaldehyde are used as the complexing and reducing agents respectively. All the stabilizers are found to improve the bath stability and produce the quality deposits. Of the four stabilizers studied, 2,2’-dipyridyl produces brightest copper deposits with more compact and finer sized...

Modelling thermal degradation kinetics of colour in curry leaf paste
Esther Magdalene Sharon, M., Kavitha Abirami, C. V. and Alagusundaram, K.

Curry leaf, has been used as a food flavourant in Asian-Indian cuisine since ancient times. The colour degradation kinetics of curry leaf paste was studied using fraction conversion technique during thermal treatment at 50, 65, 80 and 95 °C for up to 60 min. Blanched, comminuted curry leaf paste was subjected to heat treatment at selected temperatures in awater bath with agitation. Treated samples were removed from the bath at selected time intervals (0–60 min after come-up period), cooled...

An analysis of the monetary policy transmission mechanism in Nigeria
Ogunsakin Sanya

This paper examines the analysis of the transmission mechanism of monetary policy in Nigeria. To achieve the broad objective of this paper, the vector auto-regression approach is employed as estimation technique. From the empirical result, it is revealed that an increase in the interest rate tends to be accompanied by a reduction in inflation and an increase in exchange rate but show insignificant impact on the level of production. The study finally suggests that monetary authority in...

Geophysical investigations for locating buried iron slag at Lejja, Southern Nigeria
Ugwu, G. Z. and Ezema, P. O.

Archaeological geophysics involving the use of resistivity imaging and induced polarization (IP) techniques were used to locate buried iron slag and furnaces at Lejja, Southeastern Nigeria. The instrument used was the ABEM Lung measuring meter system, employing the Wenner electrode configuration. The acquired resistivity and IP data were processed and interpreted using Res2DINV software. The inverse resistivity models revealed the presence of relatively high resistivity materials of about...

Topic-digital smile designing (DSD) protocol to rehabilitate a trauma case- a case report
Dr. Prafulla Thumati, Dr. Padmaja S, Dr. Rakhi Manwani and Dr. Minal Mahantshetty

Objective - Appropriate application of principles of smile designing for any restorative work can drastically improve the esthetics of the patients. This case report describes the treatment for fractured maxillary anterior teeth using digital smile designing technique rather the conventional approach.
Background - Much Literature is available on conventional smile designing but discussion on digital smile designing is sparse. Clinical Considerations - The treatment plan included...

Slip effect on MHD oscillatory flow of fluid in a porous medium with heat and mass transfer and chemical reaction
Daniel, S., Tella, Y. and Joseph, K. M.

The slip effect on MHD oscillatory flow of fluid in a porous channel with heat and mass transfer and chemical reaction has been studied. The temperature prescribed at plates is uniform and asymmetric. A closed form analytical method is employed to solve the momentum and energy equations. The skin frictions, the Nusselt numbers and Sherwood numbers are evaluated using perturbation technique. The effects of various dimensionless parameters on velocity and temperature profiles are considered...

Hydrogenation with ruthenium nano particles supported on MCM-48
Bipul Kumar Nath and Jatindra Nath Ganguli

MCM-48 was synthesized by hydrothermal method using tetraethylorthosilicate (TEOS) and N-Cetyl-N,N,N-trimethylammoniumbromide (CTAB) as the template in a Teflon lined stainless steel autoclave at 433 K for 60 hours. The prepared MCM-48 was characterized by taking IR, XRD, SEM, EDX and Surface Area Analysis. The XRD pattern shows well ordered MCM-48 structure. The particle size was determined from the SEM image. Ruthenium nano particle were prepared by stirring Ruthenium chloride (0.0185g)...

Evaluation of cereal-legume intercropping systems through productivity and competition ability
Malay Kumar Mandal, Mahua Banerjee, Hirak Banerjee, Animesh Pathak and Rajib Das

A field experiment was carried out during kharif season of 2010 and 2011 at Sriniketan Research Farm, Visva-Bharati, West Bengal. Maize crop produced highest grain yield in sole cropping which was statistically at par with intercropping situations like maize + soybean (1:2) and maize + groundnut (2:4). The mean land equivalent ratio in two years ranged from 1.21 to 1.84, indicating biological sustainability of intercropping over sole cropping. The highest relative crowding coefficient, SPI...

Association of hba1c with prevalence and severity of coronary artery disease in diabetic and Nondiabetic patients in...
Iqra Mehraj, Irfan Yousuf Wani, Khurshid Aslam, Shariq Masoodi and Yasser Yousuf Wani

Background: Diabetes mellitus is an established risk factor for coronary artery disease (CAD). In diabetic patients measurement of glycosylated hemoglobin is a way of assessing glycemic control. The major form of glycosylated hemoglobin is HbA1c which reflects the state of glycemia over last three months.
Introduction: Studies conducted to assess the correlation of HbA1c with CAD in diabetic patients have shown it to be an important predictor. Association of raised HbA1c with CAD has...
