This study has been carried to evaluate the effect of the entomopathogenic fungi
Beauveria bassiana on the various developmental stages of Phthorimaea
operculella. Both first and second instars larvae were more susceptible than the third
and fourth instars. The infected prepupae and pupae resulted in marked decreases in
the emergence and longevity of moths, deposited eggs and egg hatchability. An
obvious increase in the pupal duration was observed and malformed adults were also
recorded. The latent was markedly obvious, especially in high doses of B. bassiana.

Let R be a non zero ring with identity and let M be a non zero module over R. An
R-module M is called cosingular if Z*(M)=M where Z*(M)={m ∈ M, mR<<E(M)},
in this paper we introduce the concept that an R-module M is weak-cosingular if
Z*(M)≤e M. and we call that an R-module has (weak-S*)property if every submodule
N of M contains a direct summand K of M such that K≤N and N/K is weakcosingular.
And we study the properties of this kind of modules, and the relation
between this modules and other kind of modules.

   Nanochemistry is a significant area which involves the synthesis, design, and manipulation of particle structures with dimensions ranging from 1 to 100 nanometres. It is now one of the major concerns of pharmaceutical and biological researchers. The current study discusses recent advances in the use of silver nanoparticles (AgNPs) as a selective sensor for qualitative and colorimetric quantitative detection of mercury ions.   The synthesis of significant noble metal AgNPs is described as a novel, low-cost, quick, and simple method for detecting mercury ions. Due to the seriousness of mercury toxicity to our cells, AgNPs may be successfully employed for the detection of ecologically harmful mercury ions in a wide variety of aqueous

The study of Mars's ionosphere was made by investigating the measurements of the electron density (Ne) depending of the variation of the solar activities through different local time, different seasons, and different altitudes. The datasets has been taken from MARSIS on board the Mars Express spacecraft, the investigation for the solar indices and the electron density (Ne) have been made for two period of time depending on the strength of the geomagnetic storms, the first one was taken when the geomagnetic storms was low as in years (1998 & 2005), the data was chosen for three seasons of these years, Winter (December), Summer (June) and Spring (April). The second period was taken for the years (2001 & 2002) when the geomagnetic s

This paper aims to study the asymptotic stability of the equilibrium points of the index 2 and index 3 Hesenberg differential algebraic equations. The problem reformulated to an equivalent explicit differential algebraic equations system, so the asymptotic stability is easily investigated. The singular points such as impasse points and singularity induced bifurcation points are identified in this kind of differential algebraic equations by using conclusion of the explicit differential algebraic equations.

In the current research work, improved and fast method to get a good approximation of the most important 256 colors of a RGB-Picture was introduced. In this paper, we propose a spatially-adaptive optimum octree quantization method for robust color printing. The goal of spatially-adaptive octree quantization is to use quantization well-suited for smooth areas, and to use octree quantization method better suited for edges. It may be useful for digital image compression, graphics- and game programmers. Also, this includes reduction of the overall number of colors, quantization or patterning the reduced number of colors, generating bitmap images, and even handling Boolean (on/off) transparency. The results show the suggested adaptive octree

In this study different methodological approaches are used and described by many features (indicators) of complex socio-economic process. Outcome of analysis has the most reliable and acceptable representation of the studied process specific to chosen case. In order to solve problems in this area (depending on the situation, case under consideration), methods from two groups are most often used: multidimensional comparative analysis and multi-criteria decision analysis. The first of these cases concern problems at the macro level (socio-economic development, demographic situation, population's living standards, etc.), in which the decisionmaker's participation is relatively small (eg the selection of diagnostic variables or expert assess
