We investigate the extent to which irreversibility of pollution shapes free-riding problems inherent in (differential) games. To this end, we use two-country differential Irreversibility is a hard type: While strictly positive and concave below certain threshold level pollution, decay drops zero above threshold. Assuming that damage function preferences are quadratic, first examine both coopera...
For most multidomain proteins the thermal unfolding transitions are accompanied by an irreversible step, often related to aggregation at elevated temperatures.As a consequence the analysis of thermostabilities in terms of equilibrium thermodynamics is not applicable, at least not if the irreversible process is fast with respect the structural unfolding transition. In a comparative studywe inves...
Human serum albumin (HSA) is known to undergo both reversible and irreversible thermal unfolding and refolding, depending upon the experimental conditions (end temperature) at neutral pH. In this report we have used high precision densimetric and ultrasonic measurements to determine the apparent specific volume (phi v) and compressibility (phi k) of HSA at different unfolded and refolded states...
If a measurement process is regarded as an irreversible process, then by Second law of thermodynamics the entropy should increase after any measurement process. By the same spirit a quantum system undergoing repeated measurement should show strong irreversibility leading to entropy production. On the contrary we show that in quantum Zeno effect setting the entropy of a quantum system decreases ...
the voltammetric behaviour of sulfadoxine (sdn) was studied at a glassy carbon electrode in 0.2 m phosphate buffer solutions using cyclic, differential-pulse (dpv) and square wave voltammetry (swv). the dependence of the current on ph, concentration, and scan rate was investigated to optimize the experimental conditions for the determination of sdn. the oxidation process was shown to be diffusi...
Background and purpose: Asthma is a widespread chronic inflammatory disease of the airways that may become uncontrollable in severe subtypes, even with radical treatments. The present study attempts to determine the risk factors of the irreversible airway obstruction in severe asthma patients. Materials and methods: The study population were 72 patients with severe asthma, aged 16- 75 year old...
Concentrated sugarcane juice (CSJ) is considered as one of the healthy sugar products, and so a potential feedstock in beverage formulations soft drinks. However, irreversible aggregates, which are unattractive to customer, found with CSJ derived from membrane filtration during storage. This study examined formation aggregates concentration CSJ, The process for goes by 3 stages, polysaccharides...
