Carbonyl sulphide (COS) is a potential tracer of gross primary productivity (GPP), assuming a unidirectional COS flux into the vegetation that scales with GPP. However, carbonic anhydrase (CA), the enzyme that hydrolyses COS, is expected to be light independent, and thus plants without stomata should continue to take up COS in the dark. We measured net CO2 (AC ) and COS (AS ) uptake rates from ...

Crisis management process has to comply with various norms and regulations; at the same time, it needs to constantly deal with uncertainty and adapt the process scenario to a current situation. These requirements make process design challenging: whereas conventional activityoriented modeling formalisms ensure process control by design, they provide only limited support for run-time adaptability...

Shadow bands, gap and pseudogaps in high-T c superconductors. Within the framework of the Charge Density Wave Quantum Critical Point (CDW-QCP) scenario for high-Tc super-conductors (HTCS), we introduce a model for tight-binding electrons coupled to quasi-critical fluctuations. In the normal state our model reproduces features of the Fermi Surface (FS) observed in ARP ES measurements on optimall...

The purpose of this project is to extend the Heston model in order to incorporate the term structure (TS) of the implied volatility surface. This includes implementing a TS within the Heston model and its calibration to a set of market instruments. The TS Heston model with piecewise constant parameters is implemented to match the TS and the COS pricing method is used for fast option pricing. We...

Abstract In this study, a multifunction polymeric adhesion promoter and anti-aging compound based on the triethanolamine salt of acrylamide acrylic acid copolymer (COS) was prepared characterized using Fourier-transform infrared spectroscopy (FTIR). The impact different COS contents tensile, adhesion, thermal properties NBR composite NBR/PET sandwich evaluated. composites containing displayed g...

Soil is a major contributor to the biosphere–atmosphere exchange of carbonyl sulfide (COS) and carbon monoxide (CO). COS is a tracer to quantify terrestrial photosynthesis based on the coupled leaf uptake of COS and CO2, but such use requires separating soil COS flux, which is unrelated to photosynthesis, from ecosystem COS uptake. For CO, soil is a significant natural sink that influences the ...

Net photosynthesis is the largest single flux in the global carbon cycle, but controls over its variability are poorly understood because there is no direct way of measuring it at the ecosystem scale. We report observations of ecosystem carbonyl sulfide (COS) and CO2 fluxes that resolve key gaps in an emerging framework for using concurrent COS and CO2 measurements to quantify terrestrial gross...

The Classroom of the Sea (COS) Project is an interactive problem-based learning environment embedded in marine science for deaf high school students to assist them in understanding and communicating scientific concepts. COS mixes a real and virtual environment for the students and teachers aboard a research vessel as they gather marine science data to address a problem. The students note the lo...

Chitosan and its oligosaccharides exhibit numerous biochemical characteristics, which includes immune enhancing, antimicrobial anti-viral properties. products have drawn much attention of both food pharmaceutical industry due to their peculiar physiochemical characteristics effectiveness in cancer therapies. Current study describes the different physiological chemical properties along with usef...
