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

Grids functionally combine globally distributed computers and information
systems for creating a universal source of computing power and information. Grid is
a very large scale, generalized distributed network computing system that can scale
to Internet-size environments with machines distributed across multiple
organizations and administrative domains. The emergence of new variety
applications demand that Grids support compatible efficient data and resource
management mechanisms, This paper provides an application level load balancing
for individual parallel jobs for grids data, implemented by using Borland JBuilder 7

Four types of surfactants derivatives of phthalic anhydride and alkyl amines consist of different length of hydrocarbon chains were prepared. The prepared surfactants were characterized by Infrared spectrophotometer and CHN analysis. The physical properties of the prepared de-emulsifiers were measured i.e. (pH, density, viscosity, CMC, molar conductivity and flash point). The efficiency of the prepared de-emulsifiers were studied with time and long side chain substituted. The hydrophilic-lipophilic balance (HLB) was calculated. The polarizability and dipole moment were studied by PM3 quantum mechanical method using the Hyperchem series program. The theoretical results were compared with the practical results
Three sites at the Al-aaras tourist island lake were selected to study the physicochemical
characters and epipelic algal communities . Monthly samples for 12 month

In vitro test has been made to find out the efficacy of aqueous and ethanolic extract of Peganum harmala seeds against Entamoeba histolytica in three concentrations (1000, 1500, 2000 μg/ml) in an exposure time of 2hrs, preliminary chemical analysis has been performed for some chemical groups which may exist in the seeds.
Results showed that all concentrations of alcohol extracts caused high mortality against parasite by using the alcohol extract in all used concentrations, this may due to the high containing of alkaloids. The highest mortality percentage achieved by alcohol extract was 97.5% while it was 90.1% by aqueous extract at 2000 μg/ml.

In this paper, a numerical approximation for a time fractional one-dimensional bioheat equation (transfer paradigm) of temperature distribution in tissues is introduced. It deals with the Caputo fractional derivative with order for time fractional derivative and new mixed nonpolynomial spline for second order of space derivative. We also analyzed the convergence and stability by employing Von Neumann method for the present scheme.
Some microorganisms, including fungi, are characterized by their removal efficiency and reducing the concentrations of heavy metals such as Pb and Cr from industrial water. The present study aims to estimate the efficiency of Penicillium digitatum (Pers.) Sacc. as a low-cost biosorbent in reducing Pb and Cr from industrial water with optimum biosorption conditions (acidity of 1.5 , 4, and 5; temperature of 30 °C). The Fourier transform infrared spectroscopy (FTIR) analysis was also used for determining the roles of the functional groups in this biosorbent. The results indicated that the highest P. digitatum efficiency values for reducing the levels of Pb and Cr were 84% and 70% , respectively, at pH of 5 after 24 h.

In industrial applications, these vibrations remain often caused by the impact of weights on the foundation machine. Typically, these basics transmit effective vertical stresses to the surface layers. Accordingly, the dynamic performance of natural clay soils under the influence of individual active loads was careful in this work. Energy A deflection scale system dropped different loads from several elevations. The application of this research was to study the surface soil responses only. These responses include the vertical displacements, velocities, and accelerations implied by impacts on t

The hydrological model was created for the watersheds of the Al-Shuwaija marsh. Sixty simulations were conducted to model the Shuwaija marsh for different return periods and rainstorms, where the model was calibrated and then validated to predict the flow and volume of water using the (WMS) program. The SCS method was used to calculate the value of the total curve number (CN) based on the land use

The proposed network self-fault management reduced the load of network traffic by reducing the request and response between the server and client, which achieves less downtime for each node in state of fault occurring in the client. The performance of the proposed system is measured by three measures: efficiency, availability, and reliability. A high efficiency average is obtained depending on the faults occurred in the system which reaches to
