We review the inventories of primordial noble gases and nitrogen in meteorites, their carrier phases, how and where they may have been incorporated, as well as processes modifying their abundances on meteorite parent bodies. Some of the many distinct noble gas and nitrogen components have an isotopic composition very different from that in the Sun. These components reside in presolar grains. “A...

Abnormal growth of population and development enormously increases energy demand. In present scenario utilization of fossils fuels to meet this demand is not enough and also leads to pollution, global warming, climate change as well as natural disaster. Therefore, hydrogen as energy carrier is a major option on these prospects as it is non-polluting and renewable. The renewable hydrogen energy ...

Worldwide research groups are searching for anticancer compounds, many of them are organometalic complexes having platinum group metals as their active centers. Most commonly used cytostatics from this group are cisplatin, carboplatin and oxaliplatin. Cisplatin was used fot the first time in 1978, from this time many platinum derivatives were created. In this review we present biological proper...

Because of growing environmental concerns and increasingly stringent regulations governing auto emissions, new more efficient exhaust catalysts are needed to reduce the amount of pollutants released from internal combustion engines. To accomplish this goal, the major pollutants in exhaust-CO, NO(x), and unburned hydrocarbons-need to be fully converted to CO(2), N(2), and H(2)O. Most exhaust cat...

[1] Noble gas concentrations and isotopic ratios are presented for 38 deep ( 0.5–3.6 km) brine samples in the Michigan Basin. These brine samples clearly show the presence of an important crustal component of He, Ne, Ar, and Xe. Both Arcrust and Xecrust display the presence of a strong vertical gradient along the sedimentary strata of the basin. We show that the in situ production for these two...

Climate changes are one of the most significant aspects, which cause a threat to all human beings living on planet Earth. could happen due both natural internal processes and external forcing, or persistent anthropogenic changes. The identified drastic temperature changes, increase in emitted greenhouse gasses, sea-level as witnessed from acquired data; such ice cores, during past centuries eve...

An apparent paradox is obtained in all previous treatments of the Trouton-Noble experiment; there is a three-dimensional (3D) torque T in an inertial frame S in which a thin parallel-plate capacitor is moving, but there is no 3D torque T in S, the rest frame of the capacitor. Different explanations are offered for the existence of another 3D torque, which is equal in magnitude but of opposite d...

Yet, when I began to set my thoughts in order, the concept of surgery and what it takes to be a surgeon proved to be elusive. Each word or definition suggested more words and more description. It began to look as if there was just too much material to describe this entity, almost “too many notes.”1 The topic would not reduce itself. I became engrossed with finding a way to adequately describe s...

We compare taxes and quotas when firms and the regulator have asymmetric information about the slope of firms’ abatement costs. Damages are caused by a stock pollutant. We calibrate the model using cost and damage estimates of greenhouse gasses. Taxes dominate quotas, as with additive uncertainty. This model with multiplicative uncertainty allows us to compare expected stock levels under the tw...
