Minimizing combine harvester rear losses by intelligent modeling of MOG passing concave
Although the mean of combine losses is about 4-5% in advanced countries, unfortunately in Iran is about 20% and higher. In order to obtain little loss it is necessary that product process such as cutting, convayting, threshing, separating, etc., would be optimized. Threshing is one of these processes which has more effect on combine performance. Reduction of MOG passing concave could reduce the load on shoes that would increase cleaning system efficiency and decrease foreign materials in the bin. In order to evaluate effecting parameters on MOG passing concave, experiments were conducted in 4×3×3 factorial pattern with Randomized Blocks design. Independent variables in this experiment were, stem height, feed rate, threshing clearance ratio and rotational speed of threshing cylinder. To offer an intelligent model to forecasting of MOG passing concave and evaluating of these parameters’ effects on MOG passing, Neurosolution was used. Multilayer Perceptron (MLP) network with four inputs and one output was used to analysise. Results showed that the amount of MOG passing concave had dependent to rotational velocity of threshing cylinder, stem height, feed rate and threshing clearance ratio, respectively. The amount of MOG passing has increased with reduction in stem height, feed rate, threshing clearance ratio and speed up of threshing cylinder.

Vibrational spectra, NBO, HOMO-LUMO and NMR (1H and 13C) analyses of 5-bromo-2-methoxybenzaldehyde
In this work, the spectral properties of 5-bromo-2-methoxybenzaldehyde (BMB) are studied using density functional theory (DFT) employing B3LYP/6-311++G (d) and B3LYP/6-311++G (d, p) levels of theory. There are four conformers, C1, C2, C3, and C4 for this molecule. The computational results diagnose the most stable conformer of BMB as the C1 form. The optimized geometrical parameters obtained by B3LYP/6-311++G (d, p) method show good agreement with experimental X-ray data. The electric dipole moment (m) and first hyperpolarizability (?) values of the investigated molecule are computed using scaled quantum mechanics (SQM) method. The calculated results also show that the BMB might have microscopic non-linear optical (NLO) behavior with non-zero values. A study on the electronic properties, such as HOMO and LUMO energies, is performed. The isotropic chemical shift computed by 1H and 13C nuclear magnetic resonance (NMR) chemical shifts of the BMB calculated using the gauge invariant atomic orbital (GIAO) method also shows good agreement with experimental observations.

Inter-mobility and interoperability between IPv4 and IPv6 networks
Transitioning IPv6 takes several challenges and hurdles. Significant work has been carried out to different transition scenarios to prove their suitability is under research. It is observed in the literature that the Internet infrastructure still has not significantly migrated from IPv4 to IPv6, even after the introduction of IPv6 in 1995. While IPv4 and IPv6 Internet infrastructures co-exists together, IPv4 mobile users should not be restricted to utilize only IPv4 based networks and IPv6 mobile users should not be restricted to utilize only IPv6 based networks. The current Internet protocols IPv4 and IPv6 adopted for the Mobile Internet connectivity provide facility for roaming of IPv4 mobile node into IPv4 based networks and facility for roaming of IPv6 mobile node into IPv6 based networks. This paper highlights the need of mobile Internet connectivity while roaming of IPv4 mobile node into IPv6 based networks and similarly while roaming of IPv6 mobile node into IPv4 based networks by providing inter-mobility and interoperability between IPv4 and IPv6 mobile nodes when they are in each other’s IP networks. This paper also emphasizes that more research have to be carried out, to design an integrated architecture addressing, inter-mobility and interoperability for IPv4 nodes in IPv6 networks and to design an integrated architecture addressing, inter-mobility and interoperability for IPv6 nodes in IPv4 networks.

The Solution of the Problem of Relation between Geometry and Natural Sciences
The work is devoted to solution of an actual problem – the problem of relation between geometry and natural sciences. Methodological basis of the method of attack is the unity of formal logic and of rational dialectics. It is shown within the framework of this basis that geometry represents field of natural sciences. Definitions of the basic concepts "point", "line", "straight line", "surface", "plane surface", and “triangle” of the elementary (Euclidean) geometry are formulated. The natural-scientific proof of the parallel axiom (Euclid’s fifth postulate), classification of triangles on the basis of a qualitative (essential) sign, and also material interpretation of Euclid’s, Lobachevski’s, and Riemann’s geometries are proposed.
