The Ammonia beccarii, Anomalina sp., Asterorotalia dentata, Ammonia tepida, Quinquloculina seminulum, Asterorotalia trispinosa, and Elphidium crispum are abundant. Anomalina sp., represent the shelf environment and it is a good indication of flooding or marine water incursion into the estuary. Q-mode cluster analysis revealed that the foraminifera could be grouped into 6 clusters. Occurrence and distribution of foraminiferal assemblages studied in the Gosthani estuary sediments, infers that these sediments were deposited in marine environment.

The present study of resulting spectra of metamorphic high grade rocks like charnockite can require striping techniques to resolve interference problems between low and high Z elements on the applications of light energy-PIXE using Si (Li) detector. In all forms of X-ray analysis, including thick-target light energy-PIXE, the X-ray signal is a dependent of the ionization cross section and for low-energy protons, the cross section is high for the K shells of light elements and the L shells of heavy elements in charnockite rock providing sufficient fluorescent yield for analytical purposes. For Z > 55, 3 MeV protons cannot ionize K-shell electrons and analysis depends on the use of L-X-ray lines in charnockite rock. Such L-X-ray spectra are complicated and can be affected by interferences K-X-rays from low Z elements. The low Z elements present in the charnockite were identified by previous complementary analytical techniques, but not identified in this study due to the above PIXE experiment limitations, and also particularly due to the dimensions of Si (Li) detector because of low energy K-X-rays of the elements absorbed by the detector window. Both interferences complexity and detector efficiency can lead to difficulties and ambiguity in the interpretation of spectra of low Z charnockite composition, a problem that is exacerbated by uncertainty in relative K-X-ray line intensities of low Z elements. From this investigation, the light energy-PIXE is ideal for the analysis of low Z<55 elements except lower K-X-rays of Z<17 elements using K-X-ray lines without high Z elements present in charnockite samples.

Protons of such energies do not accurately excite K-X-rays for high Z elements in matrix geological compositions like charnockite. In this analysis, low-energy PIXE (LE-PIXE) uses K-X-rays of Low Z elements and L-X-ray series for high Z elements. The resulting spectra between K-X-rays of light elements and L-X-rays of heavy elements can require striping techniques to resolve overlap difficulties in matrix composition. The results high Z elements in charnockite are to be expected, as the cross section for K-shell ionization of high-Z elements have greater values in the proton energy range of greater than 3 MeV in case of charnockite matrix composition. It has been suggested that the overlap of these discrete, gamma-rays with the Xray spectrum may be serious problem in charnockite high energy PIXE (HE-PIXE) work, sufficient to preclude its use as a viable analytical technique. The conclusion proves that for a very complex matrix charnockite material of unknown chemistry, a HE-PIXE analytical spectrum may contain various X-ray and gamma peaks, some of which may overlap, making the analysis of line identities and the evaluation of X-ray counts intractable. It does not however represent any intrinsic drawback in HE-PIXE, nor does it mean that HE-PIXE is any more or less intractable than many other nuclear analytical techniques. Alternatively, the same analytical tool use could be made of gamma-rays in HE-PIXE as in low energy analytical tools like PIGE, NRA or INAA to obtain the results of charnockite at high Z completely.

Satellite images of Landsat-7 ETM+ (2000) Landsat ETM+ (2010) Landsat OLV-TIRS (2016) and 1975 SI Toposheets have been used to study the temporal changes in the land use and land cover by onscreen digitisation techniques in ARC GIS 10.1 software followed by image processing to obtain changes in various classes of land use during study period from 1975 to 2016. The classes include plantation, settlements, water bodies, coastal area, wetlands, agriculture land and area under river course of both rivers. The classes, which have shown an increased area from 1975 to 2016, include Agriculture (from 56.93 % to 63.95%) and Settlements (from 1.40% to 3.43%). The classes that have shown the decreasing trend of Land Use are Plantation (from 19.76% to 13.14%), water bodies (from 2.29% to 0.77%), Wetlands (from 0.72% to 0.57%). The area under river course of both the rivers has shown a decreasing trend. The analysis reveals that due to increased irrigation facility plantation, wetlands and water bodies have brought under agricultural use and this trend need to be arrested. The Plantation area for natural resource management furthermore declines the soil erosion in between the Vamsadhara and Nagavali river area.

Statecharts can be seen as an extension of state-transition diagrams that allows modeling hierarchy, orthogonality, and interdependence. Due to their features to represent reactive systems, Statecharts have been adapted to represent and deal analytically with performance models (reactive systems whose performance is to be evaluated). An interesting feature present in Statecharts is to record the system's state, which cannot be represented in Markov models in a straightforward manner due to its "memory-less" property. The contributions of this paper are: show that Statecharts are a feasible alternative to specify a reactive system so that its performance can be evaluated by both analytical and simulation techniques; show that the inclusion of the memory representation in the Statecharts specification can indeed be mad...

By investigating the geochemical nature of complex charnockite material, the experimental factors which are related to the missing elements in this study of wide range of elements obtained from PIXE spectrum through the previous analytical techniques have been discussed.
