Honey has been used as a bio monitor to determine environmental quality in the environments which are polluted by heavy metals, radioactivity and pesticides. The study sought to determine the levels of some heavy metals (Cd, Cr, Ni, Zn, Cu, Pb, As, and Mn) in honey and assess their potential health risk to consumers. Samples of honey were harvested from within 5km of the Tamale Metropolis of Ghana. A known weight (5g) of honey samples were digested using an oxi-acidic mixture of HNO3/H2O2 and filtered into a 50ml volumetric flask. The contents of the minerals in the digests were analyzed using atomic absorption spectrometer (AAS). The analysis revealed that the concentrations of lead (79.815 ± 16.796 mg/Kg), nickel (15.785 ± 10.968 mg/Kg), copper (13.855 ± 10.213 mg/Kg) and manganese (8.215 ± 4.452 mg/Kg) in the samples exceeded the FAO/WHO maximum permissible limits. The elevated levels of these metals may be evidence of possible pollution agents (vehicular and industrial emissions, pollution of farm soils and pockets of water) in the study area. The Health Risk assessment (THQ< 1) showed no significant public health risk to consumers. However, we recommend regular monitoring of heavy metals from the natural environment of Tamale to mitigate possible future threats to public health.

Education is one of very important component of development. Progress of any country principally reflects with literacy level of the population. The Government of India has assigned high priority to the education sector not only to achieve the Univerlisation of Elementary Education by 2010 but also to improve the quality of education at all levels. Some of the initiatives such as District Primary Education Programme (1994), the Mid Day Meal Scheme (1995) and the Sarva Siksha Abhiyan (2001) have led some positive impact in elementary education, specifically in rural areas. But most of the work or research carried out for primary school education and educationist or researchers concentrated on primary education only. Therefore it is an attempt a look out to the development of upper primary school education in India.

Magnesium oxide (MgO) nanoparticles were synthesized through chemical coprecipitation followed by thermal treatment. Structural, optical and luminescence properties along with dielectric properties were studied and relaxation mechanisms were explored. The structural characterization studies confirmed the formation of nano sized MgO particles with hierarchical structures and high purity. The dielectric properties were studied in different frequency range at different temperatures. In addition, the Cole –Cole plot are used to explore the relaxation mechanism prevalent in nanostructured MgO. In dielectric materials there are multiple dipole relaxation mechanisms which give rises to spreading of relaxation time on the average relaxation time.

In this paper, a modified distributive arithmetic algorithm is designed and implemented on FPGA for OFDM system. In order to reduce the number of storage elements required to store the partial products, input register is split into two sections. Bottom section of register is used to access the partial products and the top section of input register is used as select line of multiplexer structure. The addition of partial products is executed in parallel to reduce the latency of the DWT/IDWT computation. The modified DA algorithm is modeled using HDL and is implemented on Spartan 3E devices. The design operates at 60 MHz and consumes power less than 0.036 W and is thus suitable for low power applications. The developed DWT/IDWT model can be integrated with QAM modulator and form a OFDM system used for power line applications.

Current scenario in healthcare sector in Uttarakhand is disappointing. Public health service run by Government is overburdened and collapsing. Hilly geographical size, increase population density, lack of transport, inaccessibility, illiteracy, poverty, poor nutritional status, diversity in food habit and life style are various impediments. Government priorities for providing health service to rural areas is yet to be fulfilled. At this stage low budget from state for health, lack of funds and coordination have triggered down trend in health services in rural and hilly areas. As medical science is fast developing and information resource is pouring in, there is urgent need for dissemination knowledge by interlinking primary, secondary and tertiary level health centers using the ICT and e-Governance applications. This will help health personal to deliver high quality services. IT giants are experimenting for e-Governance application in health sector both in Government and private hospitals, This paper reviews use of e-Governance through ICT applications at National Level and also in Uttarakhand province. It presents facts on tele-medicine, tele-referal services and health information dissemination by Video conferencing, Some suggested services using ICT in healthcare are explained in this paper also. Use of Mobile phone to communicate health related alerts using SMS services in rural areas suggested here in this paper.

For any graph , the lict graph of a graph is the graph whose vertex set is the union of the set of edges and set of cut vertices of in which two vertices are adjacent if and only if corresponding members are adjacent or incident .A set of edges in a graph is called edge dominating set of if every edge in is adjacent to atleast one edge in ,denoted as and is the minimum cardinality of edge dominating set in . In this paper, many bounds on were obtained in terms of vertices , edges and other different parameters of but not in terms of elements of . Further we develop its relation with other different domination parameters.

A computational study on performance and emission characteristics of single cylinder, four stroke SI engine operating on ethanol-gasoline blends was carried out on AVL BOOST at different compression ratios. In this paper Vibe two zone model was selected for the study of combustion analysis and simulation were carried out for different blends of ethanol and gasoline i.e. from 0% to 30% of ethanol by volume with the increment of 10. The computational results show that gasoline fuel produces more power and torque than E10, E20 and E30. Whereas there is a considerable decrease in the emission of HC and CO but NOX increases with increase in ethanol content.

This study investigated the effectiveness of Free Primary Education (FPE) as one of the integrated education management strategies (IEMS) on enrolment aspect of pupils’ participation in public primary schools of Kakamega County, Kenya. The study conformed to the 8-4-4 system of education in 3 phases: pre-FPE Phase( 1995 – 2002), First-FPE Phase(2003-2010) and Second-FPE Phase (2011- 2018). A sample size of 82 schools representing 30% of Public Primary Schools was purposively sampled from 273 schools in four selected sub-counties: Lurambi(20), Shinyalu(24), Mumias East(18) and Navakholo (20). The research found that FPE policy had positive impact on retention of pupils in school.

In this study, the effect of paddy dehusking rate in rubber the roll sheller at four levels of 60, 70, 80 and 90% were investigated on some milling properties as head brown rice yield (HBY), head rice yield (HRY) and whiteness of three Iranian rice varieties namely Binam, Khazar and Sepidroud was examined. The results revealed that the HBY decreased from 92.58 to 89.72%, 90.83 to 86.61% and 84.83 to 78.18% for Binam, Khazar and Sepidroud varieties, respectively as the paddy dehusking rate increased from 60 to 90%. However, the highest HRY of 82.17% was observed for Binam variety at the dehusking rate of 80% and the lowest value of 65.97% was recorded for Sepidroud variety at the husking rate of 60%. There was an increasing trend for rice whiteness with decreasing in paddy dehusking rate. It was decreased from 36.1 to 30.8, 36.5 to 30.1 and 35.4 to 29.8 for the varieties of Binam, Khazar and Sepidroud varieties, respectively as the paddy dehusking rate increased from 60 to 90%.

A teacher in an engineering college is a professional in two ways, he is an engineer and he is also a teacher. Teacher has to keep on upgrading himself in his subject and at the same time has to develop skill to translate his expertise in his field into a proper style of teaching leading to effective learning by the students. The present communication is aimed at stimulating the teacher to think, evolve and execute practice leading to effective learning by the students. Here the author presents his personal experience on some of the effective teaching techniques in teaching various subjects of Chemical Engineering at undergraduate level. Details of the methods are also given.
