Introduction： Nephrolithiasis is quite common in this part of the *** the metabolic workup Uric acid and Calcium assay are important. Calcium ＆ Uric acid lithiasis accounts for significant number of cases. But, the values given as reference do not seem to apply in tropical countries like India. We tried to analyse the values of Serum Calcium ＆ Uric acid in both normal healthy individuals and those with calculus disease in out patient department. Material and methods： The study was conducted in outpatient department wherein Serum Uric acid, Calcium ＆ Phosphorus levels were assessed in fasting state in all patients irrespective of age and sex in the period Jan. 2010- June 2015. A total of 9887 patients with stone disease were kept in Group A and 8967 patients with other diseases in group B who acted as control, were enrolled for the study. The demographic profile was recorded and associated metabolic disorders were also documented. Patients with associated features of bony pains and gout were also specified. Result： The Uric acid levels in the control group B were quite lower than the reference values in either sex. However, the values were more than 6 mg/dl in nephrolithiasis group A. The *** levels of control in group B were significantly lower than the reference value and patients with nephrolithiasis in group A also had hypocalcemia. Conclusion： Nephrolithiasis is a metabolic disorder with majority of patients having higher Uric acid levels with hypocalcemia in our *** normal values in control group is on the lower side of reference value which could be due to variation on account of climatic, dietary and geographical factors. It needs broader studies to redefine reference values of Uric acid and Calcium in tropical countries like India.

This study provides a combined analysis on the palynology, fossil charcoal and biomarkers of the subsurface coal deposits from a borehole RMB #2 drilled at the Dhulia Coal Block, Rajmahal Basin, India, in attempts to establish the chronology of sedimentation and to propose palaeobotanical as well as geochemical evidence for the occurrence of wildfires in these sediments. The palynological investigation suggests a Scheuringipollenites barakarensis palynoassemblage from the lower Barakar Formation, dated as Artinskian(Early Permian) in age. This assemblage reveals the dominance of Glossopteridales and sub-dominance of taxa belonging to Cordaitales and *** charcoal in sediments is usually recognized as a direct indicator for the occurrence of palaeo-wildfires. More data involving the anatomical features of fossil charcoal analyzed by Field Emission Scanning Electronic Microscope broaden our knowledge on Early Permian wildfires from the peninsula of India. The studied macroscopic charcoal fragments exhibit anatomical details such as homogenized cell walls, uniseriate simple and biseriate alternate pitting on tracheid walls and rays of varying heights pointing to a gymnospermous wood affinitity. The excellent preservation of charcoal fragments, shown by their large sizes and almost unabraded edges, suggests a parautochthonous origin. The embedded biomarker study performed for charcoal sediments and its characterization demonstrate the presence of n-alkanes, isoprenoids, terpenoids and aromatic compounds. A bimodal distribution pattern of n-alkanes with a Cmaxat n-C25 is identified. Diterpenoids and pentacyclic terpenoids are identified, indicating the input of an early conifer vegetation and bacterial activity, respectively. The identified polyaromatic hydrocarbon(PAH) compounds, together with the charcoal fragments, clearly suggest that repeated wildfire events occurred during the deposition of these Artinskian sediments in the Rajmahal Basin.

To overcome the shortcomings of 1 D and 2 D Otsu’s thresholding techniques, the 3 D Otsu method has been *** all Otsu’s methods, 3 D Otsu technique provides the best threshold values for the multi-level thresholding processes. In this paper, to improve the quality of segmented images, a simple and effective multilevel thresholding method is introduced. The proposed approach focuses on preserving edge detail by computing the 3 D Otsu along the fusion phenomena. The advantages of the presented scheme include higher quality outcomes, better preservation of tiny details and boundaries and reduced execution time with rising threshold levels. The fusion approach depends upon the differences between pixel intensity values within a small local space of an image;it aims to improve localized information after the thresholding process. The fusion of images based on local contrast can improve image segmentation performance by minimizing the loss of local contrast, loss of details and gray-level distributions. Results show that the proposed method yields more promising segmentation results when compared to conventional1 D Otsu, 2 D Otsu and 3 D Otsu methods, as evident from the objective and subjective evaluations.
