The present study explores the temperature-dependent aqueous speciation of major ions (cations and anions) in Gujarat geothermal waters to better constrain reservoir fluid composition. For this purpose, water samples from Dholera Tuwa region have been chosen for calculation as (DH-1) (TA-3) thermal give lower (138 ± 7°C) upper (166 12°C) range temperature, respectively. In both samples, concentrations free are found be highest compared their complexed species. Among all ionic species,...
The thermal springs of the study area are situated in North-eastern Arunachal Himalayas, India along Subansiri and Siang River valleys with surface temperature ranging between 20 57 °C. pH varies from 7.69 to 9.31, indicating near neutral alkaline nature non-thermal waters. major geochemical processes influencing hydrochemistry demonstrated using conventional graphical plots, modelling by PHREEQC multivariate statistical analysis. waters Chetu Taksing valley primarily Na–Cl Na–HCO3 type,...
Geothermal energy, with associated low-carbon emissions compared to conventional fossil fuels, is presently one of the potential renewable energy sources. The decryption chemistry thermal manifestations geothermal systems, in terms relative abundances various chemical facies, mandatory before launching systematic exploration a given area as it provides valuable information on basic characteristics reservoir. For present study, three clusters hot springs have been selected -1) Shyok-Nubra...
A self-consistent theory of a free-electron laser is developed by the kinetic approach, using method characteristics in helical wiggler and guide magnetic fields. The detailed relativistic particle trajectories obtained fields are used linearized Vlasov–Maxwell equations having variations perpendicular parallel momenta to obtain perturbed distribution function terms electric deviating from vector potential approach. thus obtained, for an arbitrary function, current, conductivity dielectric...
The present study area, Puga, is located along the inflexion point of Indian and Asian plates comprising zone anatectic melting, where thermal activity attributed to extensive igneous during Upper Cretaceous late Tertiary age. area characterized by geysers, past fumaroles, steaming grounds mud pools with vast spread sulfur, carbonates borax deposits surface temperature hot springs 84°C, which boiling water at ~ 4500 m above mean sea level. It only known geothermal system rare alkali...
A conceptual model has been proposed based on water samples collected from geothermal springs in the Shyok suture zone of North-West Himalayas, Ladakh province, India by nurturing hydrogeochemistry, mineralogical insights, and stable isotopic (δD, δ18O) systematics. The reservoir rock is comprised granitic segment with intrusion volcano-plutonics a variety meta-sedimentaries which becomes more exposed towards western side valley form Ophiolitic melange. Thermal waters, located above 3100 m...
The stability analysis of Soret driven double diffusive convection for electrically conducting couple stress liquid is investigated theoretically. confined between two horizontal surfaces and a constant vertical magnetic field applied across the surfaces. Linear used to investigate effect various parameters on onset convection. Effect presented by means Chandrasekhar number. problem analyzed as function number (Q), positive negative parameter (S r) (C), mainly. results show that Q, both Sr C...
The role smokes in warfare is reviewed with particular reference to the world wars, and various types os are discussed. that can defeat modern opto-electronics including infrared (IR)/millimetre wave (MMW) guidance thermal imager described. Environment-friendly non-toxic dealt briefly. future of these circumstances mentioned.
A self-consistent kinetic theory of the free-electron laser is developed based on method characteristics in circularly polarized, periodic, static helical wiggler, and guide magnetic fields. The detailed relativistic particle trajectories obtained wiggler fields are used linearized Vlasov–Maxwell equations having variations perpendicular parallel momenta to obtain perturbed distribution function terms electric thus obtained, for an arbitrary function, current, conductivity, dielectric...
Summary An assessment has been done on the prospectivity of Makhul formation (Tithonian To Berriasian) for unconventional resources in Kuwait fields. It is observed that Lower part Formation only likely potential target hydrocarbon exploration as evidenced from geochemistry data. A wide variation organic content noticed layer to layer. The porosity within matter (less than 1 2%) at nano micron resolution Micro CT,2DSEM measurements. Considering high heterogeneity and mineralogy this...
The present trend abroad is to replace conventional smoke compositions with castable type of because superior performance the latter over former. technology screening smokes has been recently developed for first time in India by Explosives Research & Develop- ment Laboratory, Pune. This paper discusses various advantages large scale manufacture composition. A comparison also made method composition currently followed.
