An attempt is made to present some experimental predictions of the five dimensions Kaluza–Klein theory. The conversion of photons into dilatons in the static magnetic fields are considered in detail. The differential cross-sections are presented for the conversions in a magnetic field of the flat condensor and a magnetic field of the solenoid. A numerical evaluation shows that in the present technical scenario, the creation of dilatons at high energies may have the observable value.

The effects of capillary grooves on surface wetting and evaporation have been analysed. An attempt has been made to obtain expressions which approximately describe the increase in heat transfer in order to select for given properties and temperature differences a groove of optimum design. For this purpose, it is assumed that the heat transfer mechanism is determined by thermal resistance of the liquid layers inside the grooves. From a numerical evaluation of linearized equations, heat transfer rates have been computed for grooves with triangular, semicircular, and square cross sections.

The Magnetic Field

The classical processes: the conversion of photons into gravitons in the static electromagnetic fields are considered by using Feynman perturbation techniques. The differential cross-sections are presented for the conversion in the electric field of the flat condenser and the magnetic field of the solenoid. A numerical evaluation shows that the cross-sections may have the observable value in the present technical scenario.

<p style="text-align: justify;"><strong>Aims</strong>: To detect and identify the cultivable microorganisms putatively associated with esca disease in representative Lebanese vineyards.</p><p style="text-align: justify;"><strong>Methods and results</strong>: Two field surveys were conducted in Lebanon in 2005 and 2007 to study the fungal community associated with grapevine wood lesions. A total of 68 vines showing typical esca symptoms were randomly sampled in 17 vineyards and cross sections were obtained of cordons and trunks. The shape and type of inner necrosis and discoloration were examined and isolations were made from the symptomatic wood. Isolation results showed that inner necrosis and isolated fungi were similar to those previously found elsewhere, namely in Central Europe or Mediterranean countries. Additionally, three methods for numerical evaluation of micro-organisms found were compared.</p><p style="text-align: justify;"><strong>Conclusion</strong>: Most fungal pathogens generally associated with grapevine trunk diseases were detected, of which the basidiomycete <em>Fomitiporia mediterranea</em> and species of the ascomycete family <em>Botryosphaeriaceae</em> were the most frequently encountered. Additionally, a large diversity of other wood colonizing micro-organisms was detected. The putative role of some of the obtained micro-organisms in the process of wood degradation related to esca disease is discussed.</p><p style="text-align: justify;"><strong>Significance and impact of the study</strong>: This isolation study is presently the most completed that was carried out with grapevine wood samples collected in Lebanon. Besides, it is the first to provide isolation results based on a classification of inner necrosis in five categories and to compare three criteria for numerical evaluation. This study also tends to further highlight that <em>Botryosphaeriaceae</em> species are common wood inhabiting fungi that should be associated with esca.</p>

Analytical Expressions

A general analytical expressions for the cross-section and the polarization of nucleons arising in the inclusive deuteron stripping reaction have been derived in the diffraction approximation. The nucleon–nucleus phases were calculated in the framework of Glauber formalism and making use of the double-folding potential. The tabulated distributions of the target nucleus density and the realistic deuteron wave function with correct asymptotic at large nucleon–nucleon distances were used. The calculated angular dependences for the cross-sections and the analyzing powers of the [Formula: see text] reaction are compared with corresponding experimental data.

Induced Currents

Horizontal patterns of antennas near conducting towers of square and triangular cross sections are found by numerical evaluation of the integral equations for the induced currents. The computed patterns for moderate cross-sectional dimensions of the prisms and their distance from the antenna are presented and some similarities with the patterns of circular cylindrical towers are established.
