It is appreciated that the olives in Romania have recorded higher prices, so in this paper it is desirable to analyse exactly the evolution of the prices for the olives, but also the main factors that can influence these changes, such as import prices, the situation of the areas and production...

Romania is a country with a high production potential for the vegetables and fruits, due in particular to the high natural fertility of soils and to the climate diversity. Besides the favorable conditions for the production of fruits and vegetables, it should be mentioned that Romania is a...

Wool fiber is commonly used in textile industry, however, it has some technical problems which affect the quality and performance of the finished products such as felting shrinkage, handle, lustre, pilling, and dyeability. These problems may be attributed mainly in the presence of wool scales on...

Microstructure evolution of shot peened S30432 austenitic stainless steel under external loading was investigated by X-ray diffraction method. The domain size, micro-strain, and dislocation density were calculated by Voigt method and Williamson method, respectively. The results show that the...

With the proposal by H.E. Stanley and coworkers and the late G.W. Robinson and his coworkers that liquid water exists as two rapidly exchanging microdomains of different densities, the already complex living cell has acquired new levels of complexity. Microdomains are apparently of the order of...

In the framework of SOS models, the dynamics of isolated and pairs of surface steps of monoatomic height is studied, for step–edge diffusion and for evaporation kinetics, using Monte Carlo techniques. In particular, various interesting crossover phenomena are identified. Simulational results...

We report the inclusion of temperature effects on the Mahan-Nozières-De Dominicis framework to study both many-body and temperature effects in photoluminescence spectra of doped semiconductors. The electronic part of the correlation function characterizes the photoluminescence spectra. We have...

We present investigations of the electronic and magnetic structure of the Rare Earth valence states. In particular, we have examined ultra thin films (≤ 10 ML) of the rare earth metals gadolinium and neodymium epitaxially grown on tungsten (110). Various experiments on dichroism in angular...

A model study of the characteristic signatures of carrier-correlation effects on the excitonic differential absorption spectra in semiconductors is presented. Using an effectively one-dimensional tight-binding system Coulomb-induced carrier-correlations up to third-order in the optical field are...
