The aim of this study was to determine the characteristics of the distribution of energy plant moisture content along the height of their shoots and the dynamics of moisture during storage in natural conditions. The shoots of Spartina, Miscanthus and willow were used in the study. Entire shoots were cut into sections of 10 cm and for each set in monthly cycles for six months moisture content was evaluated. After a month＇s storage of freshly cut shoots the biggest decrease of content moisture in the shoots of Spartina and Miscanthus was recorded, by 31% and 22%, respectively, and the lowest in willow shoots （12%）. After sixth months of shoots storage the lowest moisture content （10%-12%） was reached in miscanthus. The most uneven moisture content along the height of shoots Spartina was characterized because on one third of the height from the bottom, the moisture content of shoots was 20%, and the top had moisture content in the range 5%-10%. Willow shoots were characterized by the smallest drop in moisture, and the final moisture content was about 23%, with the top part of moisture content of 10%-20%. The dynamics of moisture change during the six months of storage of grass shoots （Miscanthus and Spartina） in natural conditions under roofing was described by one power function regression, and willow by another one. Empirical models can be used to predict changes in moisture content of these plants in experiment conditions, since the coefficients of determination were 94.66% and 89.18%, respectively.

This paper focuses on an analysis of the surface texture formed during precision machining of tungsten carbide. The work material was fabricated using direct laser deposition （DLD） technology. The experiment included precision milling of tungsten carbide samples with a monolithic torus cubic boron nitride tool and grinding with diamond and alumina cup wheels. An optical surface profiler was applied to the measurements of surface textures and roughness profiles. In addition, the micro-geometry of the milling cutter was measured with the appli- cation of an optical device. The surface roughness height was also estimated with the application of a model, which included kinematic-geometric parameters and minimum uncut chip thickness. The research revealed the occurrence of micro-grooves on the machined surface. The surface roughness height calculated on the basis of the traditional kinematic-geometric model was incompatible with the measurements. However, better agreement between the theoretical and experimental values was observed for the minimum uncut chip thickness model.

We investigate a reaction-diffusion model in which a Turing pattern develops and reproduces the formation of periodic segments behind a propagating chemical wave front. The chemical scheme involves two species known as activator and inhibitor. The model can be used to mimic the formation of prevertebrae during the early development of vertebrate embryo. Deterministic and stochastic analyses of the reaction-diffusion processes are performed for two typical sets of parameter values, far from and close to the Turing bifurcation. The effects of a local source or sink of inhibitor on the growing structure are studied and successfully compared with experiments performed on chick *** show that fluctuations may lead to the formation of additional prevertebra.

ABSTRACT The Pauwels Classification of femoral neck fractures, initially published in 1935, is used world-wide. Unfortunately, modern textbooks give varying angle and anatomic specifications between the classified fracture grades. This inconsistency is perpetuated in the literature, so that it is difficult to compare conclusions made by different authors. Pauwels himself left room for interpretation. He published two studies, one in 1935 and one in 1973, each including 3 diagrams. The 1935 version cited an angle of 8° representing the vector of static forces acting on the femoral head. The 1973 diagrams, however, cited an angle of 16° to represent dynamic forces, without changing the angle from horizontal. This already complex sche- me is complicated by the fact that it depends on other factors such as femoral neck shaft (CCD) angle, femoral neck and head diameter, and/or distance of the fracture from the center of the femoral head. The multitude of factors argues against a rigid classification based on fixed angles from horizontal. Pauwels himself did not establish fixed critical angles between the fracture grades. In his own explanation of the system, he placed more value on mechanical considerations such as compression stress, shear stress, tensile force, shearing force, and torque. We propose therefore a simplified version of the Pauwels Classification: Grade I for fractures impacted in valgus, Grade II for fractures without free torque, and Grade III for fractures with free torque.
