Solutions of the proteins represent in one sense simple systems, rather than complex ones. The properties of proteins in solutions which depend more or less upon changes in electric charge can be investigated directly through the study of the electric mobility of the protein ions 1 and indirectly by means of titration curves with acids, optical rotation, viscosity, etc. If one makes certain ass...

Measurement of optical rotation in RbTiOAsO4 (RTA) with the tilter method resulted in an optical rotation of r12 1⁄4 þ17ð3Þ /mm at a wavelength of 670 nm, when a (100) sample was tilted about [001]. A tilt about [010] showed no rotation, as expected from the directional dependence of optical rotation calculated from the tensor in point group mm2. The absolute Miller-indices of the samples were ...

The using possibility of the vortex light beam with topological charges 2 and 5 for the rotation of the micromechanical element (microturbine) was considered. The results of the full-scale experiment on the optical rotation of the special form microturbine were presented. We evaluated the force moment, acting the microturbine.

The tillage-based winter wheat (Triticum aestivum L.)-summer fallow (WW-SF) cropping system has dominated dryland farming in the Pacific Northwest USA for 125 years. We conducted a large-scale multidisciplinary 8-year study of annual (i.e., no summer fallow) no-till cropping systems as an alternative to WW-SF. Soft white and hard white classes of winter and spring wheat, spring barley (Hordeum ...

Nutrient content (Nitrogen, Phosphorous, Potassium) monitoring in soils is essential for the proper use of fertilizers to minimize environmental impact wrong pattern fertilization practice. Collecting samples from different locations and laboratory testing takes longer costs a lot. New-generation digital sensors are smart enough replace chemical lab real-time with minimum effort almost precise ...

Three-dimensional photonic crystals (3D PhCs) are a fascinating platform for manipulating photons and controlling their interactions with matter. One widely investigated structure is the layer-by-layer woodpile structure, which possesses a complete photonic bandgap. On the other hand, other types of 3D PhC structures also offer various possibilities for controlling light by utilizing the three ...

We propose to implement a \multi-argus" facility at CFHT. The main scientiic driver of this project is the study of the evolution of the Tully-Fisher relation at intermediate redshift, thanks to the use of the optical rotation curves of spiral galaxies. The multiplex gain makes this project quite attractive, even on a 4m-size telescope such as CFHT. From the instrumental side, the idea is to mo...

In recent, Kar.S et.al [ Phys Rev D 67,044005 (2003) ] have obtained static spherically symmetric solutions of the Einstein-Kalb-Ramond field equations. We have shown that their solutions, indeed, represent Wormholes. In Einstein-Cartan theory, the symmetric Christoffel connection is modified with the introduction of an anti-symmetric tensorial term,known as space time torsion, which is presume...

Organic farming technology may be relatively unknown to farmers at the time when they switch from conventional into organic farming. Therefore, experience gained over time and learning by doing may be important determinants in the efficiency of organic farming. It may also take time to reach the optimal nutrient stock of soil and optimal nutrient supply for arable crops under organic farming. T...

INTRODUCTION Occupational exposure to noxious dusts, gases, and fumes most likely contributes to obstructive lung disease. We studied whether self-reported farming work is associated with non-reversible airways obstruction. METHODS Following the burden of obstructive lung disease (BOLD) study protocol, we surveyed a gender-stratified population-based sample of 2,200 adults aged 40 years and o...
