The Line graph L(G) of an undirected graph G is another graph L(G) that represents the find adjacencies between the edges of G. In this paper, we find the Maximum and Minimum of total coloring for a certain Line graphs of a snake graph families and further we established the results on maximum number colors required to total coloring to the graph G is denoted by and similarly we color the vertex of a snake graph and obtained certain results and denoted by X_Max^(G)

The difficulty of calculating transient heat transfer in foamed concrete panel is complex due to its porous and multi-phase material nature. This paper reports the basis of one-dimensional Finite Difference method to acquire thermal properties of foamed concrete. Additionally, this paper also incorporates the execution of the method and the validation of thermal properties model of foamed concrete. A one-dimensional finite difference heat conduction programme has been developed to predict the temperature development through the thickness of the foamed concrete slab, based on an initial estimate of the thermal conductivity-temperature relationship as a function of porosity and radiation within the voids. The accuracy of the model was evaluated by comparing predicted and experimental temperature profiles obtained from small scale heat transfer test on foamed concrete slabs, so that the temperature history of the specimen calculated by the programme closely matches those recorded during the experiment.

In this paper, various generalized imputation procedures have been suggested and their corresponding families of estimators of population mean have been considered. Asymptotic expressions for biases and mean squared errors have been obtained. Optimum conditions are investigated at which the proposed family of estimators has minimum mean squared errors. It has been shown that the proposed imputation procedures and the resulting families of estimators due to Singh and Horn (2000), Ahmed et al. (2006), Shukla and Thakur (2008) and Pandey et al (2015) are members of the suggested procedures and estimators. The results of this paper are general and of immense useful.

Green leafy vegetables play an important place in a well-balanced and healthy diet Aim: To determine the mineral and anti-nutrient content of fresh GLV, quantify the change on drying Results: Two common (Moringa oleifera and Trigonella foenum graecum) and two uncommon (Boerhaavia diffusa and Trianthema portulacastrum) greens were selected. Their ash content ranged from 1.75±0.19 (T. foenum graecum) to 3.63±0.16 g/100g (B.diffusa) in fresh leaves. In dried leaves the ash was between 10.57±0.19 (M. oleifera) and 18.98±0.26 g/100g. (T.portulacastrum).T.foenum graecum had the least iron (3.79±0.2mg), M.oleifera had the highest (4.43±0.16 mg/100g) iron. Phytate content was 2.46±0.13 (T.portulacastrum) to 5.24±0.20 (B.diffusa) mg in fresh leaves. Conclusion: Drying concentrates the nutrients and antinutrient content

Coal is the major source of electricity in South Africa and a large volume of coal fly ash waste is generated by the thermal fired power stations which have become a serious environmental issue because of the problem of the disposal. The aim of this research is to assess the quality and beneficiation of the coal fly ash samples. The fly ash sample was characterized using analytical techniques such as X-ray diffraction (XRD), X-ray fluorescence (XRF), scanning electron microscopy (SEM) and Fourier transform infrared (FTIR) spectroscopy. The morphology of the fly ash is spherical and the XRD identified mullite, gypsum, magnetite, lime, quartz and hematite mineral phases. The elemental composition of the fly ash using XRF containing major elements: SiO2, Al2O3, Fe2O3, CaO, while the minor elements are P2O5, SO3, MgO, NaO, TiO2, and V2O5. The result shows that the coal fly ash sample is class C ash with high pozzolanic properties that is suitable to be used for making concrete or cement.

Mucinous tubular and spindle cell renal cell carcinoma is a rare tumor described in the 2004 WHO classification as a new entity with an indolent clinical course. In this study, we report the case of a 60-year-old man with a large mass involving the upper pole of the left kidney. The patient underwent left radical nephrectomy. The histological findings showed it to be a mucinous tubular and spindle cell renal cell carcinoma of grade 1 of Fuhrman’s classification with hilar infiltration. Because of the favorable outcome of this histological entity, mucinous tubular and spindle cell carcinoma must be differentiated from papillary renal cell carcinoma, especially from the variant with sarcomatoid dedifferentiation. The aim of this work is to draw the attention of pathologists and clinicians to this new entity, and the importance of its diagnosis for the patient’s prognosis.

Two simple and sensitive spectrophotometric methods (Method A& Method B) in the visible region have been developed for determination of Entacapone in bulk and pharmaceutical formulations. Method A is based on Oxidation of Entacapone with Fe(III) under controlled experimental conditions followed by complex formation between Fe(II) and bathophenanthroline to give red colored complex which can be measured at 535 nm. Method B (p-nitroaniline) is based on electrophilic aromatic substitution to form brown colored complex which can be measured at 470 nm. The color obeyed Beer’s law in the concentration range of 2-10 ?g/ml for Method A and 10-50 ?g/ml for Method B respectively. When Pharmaceutical formulations (Tablets) containing Entacapone were analyzed, the results obtained by proposed methods are in good agreement with labeled amounts. Recovery in both methods was 98%-102%.

Prior knowledge about the presence of a plant pathogen in an infected plant material and natural reservoir is the first requirement for a successful disease management strategy. This becomes more crucial in case of quarantine pathogen like T. indica in order to alleviate unnecessary restrictions that prevent the movement of wheat across the globe and tells how this pathogen hinders the wheat trade of India. More over the potential risk of its dissemination in international wheat trade and germplasm exchange, there is a need for quick, sensitive, reliable and alarming method to identify T. indica to facilitate implementation of specific disease control strategies and for accurately selecting areas for quarantine. The detection of Karnal bunt (KB) is based primarily on the presence of teliospores on wheat seeds. However, accurate and reliable identification of T. indica teliospores by spore morphology alone is not always possible. Research based on genomic advances and innovative detection methods as well as better knowledge of the T. indica life cycle will facilitate their early and accurate detection, thus improving the sanitary status of cultivated plants in the near future. A new, novel, highly accurate molecular tests are emerging which help in surveillance of KB. This brief review will present the overview of classical and emerging T. indica detection and diagnosis assays and a repertoire of molecular diagnostic tools that can serve as a foundation stone for identifying and detecting T. indica inoculum load on multiple, rapid-cycling, real-time, PCR platforms both in vitro and in vivo conditions. This also provide an efficient way for disease surveillance and disease forecasting

The combined effects of thermal radiation and viscous dissipation on unsteady, laminar, free convective flow with heat and mass transfer over an incompressible viscous fluid past a non-isothermal vertical cone with variable surface temperature and concentration are considered in this article. The dimensionless governing equations of the flow that are unsteady, coupled and non-linear partial differential equations are solved by an efficient, accurate and unconditionally stable finite difference scheme of Crank-Nicolson type. The velocity, temperature and concentration fields have been studied for the effect of Eckert number (Ec), Prandtl number (Pr), radiation parameter (F), Schmidt number (Sc), buoyancy ratio parameter (N), semi vertical cone angle ( ), surface temperature power law exponent (n) and surface concentration power law exponent (m). The local skin-friction, Nusselt number and Sherwood number are also presented and analyzed graphically. It is observed that, when the radiation parameter increases, the velocity decreases close to the cone surface and an increase in Eckert number is observed to increase both velocity and temperature. The present results are compared with the available results in literature and are found to be in good agreement.
