The Markandeya River Basin stretches geographically from 15o56′ to 16o08′ N latitude and 74o37′ to 74o58′ E longitude, positioned in the midst of Belgaum district, in the northern part of Karnataka. The groundwater quality of 54 pre-monsoon samples in the Markandeya River Basin was evaluated for its suitability for drinking and irrigation purposes by estimating pH, EC, TDS, hardness and alkalinity besides major cations (Na+, K+, Ca2+, Mg2+) and anions (HCO3–, Cl–, SO42–, pO43-, F-, NO3–), boron, SAR, % Na, RSC, RSBC, chlorinity index, SSp, non-carbonate hardness, potential Salinity, permeability Index, Kelley’s ratio, Magnesium hazard and Index of Base Exchange. Negative Index of Base Exchange indicates the chloro-alkaline disequilibrium in the study area and the majority of water samples fall in the rock dominance field based on Gibbs’ ratio. permeability indices of classes I and II suggest suitability of groundwater for irrigation. Based on Cl, SO4, HCO3 concentrations, water samples can be classified as normal chloride (96.3%) and normal sulfate (94.4%) and normal bicarbonate (44.4%) water types.

Current guidelines for implantable cardioverter-defibrillator （ICD） therapy in heart failure patients were established by multiple device Irials; however, very few geriatric patients （patients ≥ 65 years old） were included in these studies. This article explores the controversies of ICD implantation in the geriatric population, management of delivered ICD therapy in this age group, and the end of life care in patients with ICD.

In this paper, we have introduced a six-compartmental epidemic model with hand, foot and mouth disease （HFMD） infection. The total population is divided into six subclasses, namely susceptible, exposed, infective in asymptomatic phase, infective in symptomatic phase, quarantined and recovered class. Some basic properties such as boundedness and non-negativity of solutions are discussed. The basic reproduction number （R0） of the system is obtained using next generation matrix method. Then the deterministic dynamical behaviors of the system are studied. Our study includes the existence and stability analysis of equilibrium points of the system. The sensitivity analysis of our system helps us to find out the parameters of greater interest. Next, we deal with the epidemic model with three controls （two treatment controls with quarantine control）. We show that there exists an optimal control, which is effective in controlling the disease outbreak in a cost effective way. Numerical simulation is presented with the help of MATLAB, which shows tile reliability of our model from the practical point of view.

previous studies have shown that the ascending, oxidizing brines play a very important role in Kupferschiefer mineralization. Fractures could be the pathway of the brines. In order to clarify the influences of the brines on bulk organic matter, aromatic hydrocarbons and Kupferschiefer mineralization, one veinlet Kupferschiefer profile from the Lubin mine, southwestern poland was studied with the microscopic, geochemical and Rock-Eval methods. The microscopic results indicate that organic matter of the veinlet sample consists dominantly of bitumen. Its extract content is higher than in other samples. The dominant aromatic compounds are naphthalene and alkylated naphthalenes (Na-pAH), which have migrated into the veinlet sample from other sediments. The content of phenanthrene and its methylated derivatives (ph-pAH) is much lower than in other samples. The reason may be due to their heavier mass than Na-pAH. It is more difficult for ph-pAH to migrate. The Na-pAH was probably removed from the shale by distillation and enriched in fractures because of their relatively low boiling point. The content of biphenyl and alkylated biphenyls (Bi-pAH) indicates the influence degree of oxidizing fluids. Their content in the veinlet sample is higher than in other sample. The high Tmax value of the veinlet sample also reveals a more intense influence of the oxidizing fluids than in other samples. Besides the higher Tmax value, its HI value is higher than in other samples. One can presume that its original hydrocarbon content should be higher than this value because they could be partly depleted by the brines.
