proteomics concerns itself with the characterization and function of all cellular proteins, the ultimate determinants of cellular function. mass spectrometry has emerged as the preferred method for in-depth characterization of the protein components of biological systems. using mass spectrometry, key insights into the composition, regulation and function of molecular complexes and pathways have...

Climate is a complex system which is changing mainly due to the increase of greenhouse gases. Because of the importance of climate change and the effects it can have on water resources, in recent years, this topic has been taken into consideration for different basins on Earth. The objective of this study is to investigate the effects of climate change and forecasting meteorological variables o...

The effect of sonication temperature on the debundling of carbon nanotube (CNT) macro-bundles is reported and demonstrated by analysis with different particle sizing methods. The change of bundle size over time and after several comparatively gentle sonication cycles of suspensions at various temperatures is reported. A novel technique is presented that produces a more homogeneous nanotube disp...

Porous polyethersulfone membranes as used in oenology were investigated in order to evaluate temperature-dependent permeances in a temperature range from 10 to 35 °C. A temperature correction factor was determined for this type of membrane to get accurate and comparable results for further developments. Moreover, the membranes were modified with a bio-inspired polydopamine coating in order to r...

There are fewer problems encountered with optical voltage transducers in comparison with their inductive and capacitive counterparts. Although capacitive and inductive transformers are used vastly for the purpose of measurement and protection in the networks, they cause problems such as core saturation and improper transient responses which decrease the accuracy of measurement and eficiency of ...

Colloidal nanocrystals have long been used to study the dependence of phase stability and transitions on size. Both structural phase stability and phase transitions change dramatically in the nanometre size regime where the surface plays a significant role in determining the overall energetics of the system. We investigate the solid–solid phase transformation of crystallization in amorphous GeT...

climate change which is derived by increase of atmospheric co2 concentration and other greenhouse gases could have considerable effects on productivity of crops in the future. climate change impacts on chickpea yield were investigated and yield maps of dryland areas of zanjan province were provided. investigated scenarios were control scenario, in which simulated current situation, and climate ...

adenosine deaminase is an aminohydrolase (ec 3.5.4.4) which participates in the purine metabolism where it degrades either adenosine or 2'-deoxyadenosine producing inosine or 2'-deoxyinosine, respectively. the enzyme contains a parallel alpha/beta -barrel motif with eight central beta strands and eight peripheral alpha helices. ada is located both in the cytosol and on the cell membrane. since ...

Phase change materials based on chalcogenides are key enabling technologies for optical storage, such as rewritable CD and DVD, and recently also electrical nonvolatile memory, named phase change memory (PCM). In a PCM, the amorphous or crystalline phase affects the material band structure, hence the device resistance. Although phase transformation is extremely fast and repeatable, the amorphou...
