This paper deals with the implementation of Simple Algorithm for detection of range and shape of tumor in brain MR images. Tumor is an uncontrolled growth of tissues in any part of the body. Tumors are of different types and they have different Characteristics and different treatment. As it is known, brain tumor is inherently serious and life-threatening(More)
In the present investigation an attempt was made to prevent ulcerative colitis and to improve the patient compliance by developing enteric coated (EC) tablets of prednisolone and to reduce the side effects of anti inflammatory drugs in G.I.T. by developing conventional tablets of prednisolone by wet granulation technique and the prepared prednisolone based(More)
Three-month-old mulberry (Morus alba L.) cultivars (salt tolerant cv. S1 and salt sensitive cv. ATP) were subjected to different concentrations of NaCl for 12 d. Leaf area, dry mass accumulation, total chlorophyll (Chl) content, net CO2 assimilation rate (P N), stomatal conductance (g s), and transpiration rate (E) declined, and intercellular CO2(More)
Aim: The present study was sought to investigate the antidiabetic and wound healing activity of bark extract of Polyalthia longifolia against alloxan induced diabetic rats. Method: The antidiabetic activity is evaluated by estimating the blood glucose level, total protein, total cholesterol, creatinine and blood urea and nitrogen in alloxan induced diabetic(More)
Fourier transform Raman and infrared spectra of 4-hydroxy-2,6-dimethyl pyrimidine (HDMP) were recorded and interpreted by comparison with respective theoretical spectra calculated using HF and B3LYP methods. The HDMP equilibrium geometry with Cs symmetry, harmonic vibrational frequencies, infrared and Raman intensities were determined using HF/6-311G and(More)
The FT-IR and FT-Raman spectra of 4,6-dichloro-2-(methylthio)pyrimidine (DMP) have been recorded and analyzed. The optimized geometry, intramolecular hydrogen bonding, and harmonic vibrational wave numbers of DMP have been investigated with the help of B3LYP density functional theory (DFT) method supplemented with 6-31G** basis set. The infrared and Raman(More)
The FT-IR and Raman spectra of 2, 6-dichloro-3-nitrobenzoic acid (DCNBA) have been recorded and analyzed. The equilibrium geometry, various bonding and harmonic vibrational wavenumbers have been calculated with the help of density functional theory (DFT/B3LYP/cc-pvdz/6-311++G(d,p)) method. The optimized geometrical parameters obtained by B3LYP/6-311++G(d,p)(More)
In contrast to fossil fuels, the use of biofuels for thermal applications and power generation provides significant environmental advantages. Since Bio-Oil is extracted from organic wastes, it is a CO2 Neutral technique and can generate CO2 credits. In the present scenario energy sectors and individual entrepreneurs can opt a new way of power generation(More)
