Regression analysis is used for the estimation of the pKa values, %analgesic activity (%AA) and % decreasing activity of central nervous system (CNS) depressant property (%DA) of eight substituted imidazolin-5(4H)-ones by using various types of descriptors as parameters. These parameters are based on quantum chemical treatments. They were derived by employing semi-empirical calculations represented by Austin model 1 (AM1). The parameters used for representing the variation observed in the pka values, %AA and %DA are atomic, structural, and molecular properties, including charges on hetro atoms present in the compounds, energies of HOMO (EHOMO) and LUMO (ELUMO)orbitals, hardness of molecules (η) , chemical potential (μ) electrophilicity index (ω), total energy (TE), stretch (Str), bend (Bd), 1,4-Vander Waals interactions (1,4VDW), and Non1,4- Vander Waals interactions (Non 1,4-VDW). The relation of pKa, %AA, and %DA and each of these parameters of the studied compounds is investigated.
Depending on these relations, three sets of parameters were constructed, each of them representing the most sufficiently and reliable set to describe the effect of substituents and structure of imidazolinone under consideration on the studied properties with highly predictive power indicated by high consistency between the calculated and experimental values expressed by correlation coefficient values (R2) close to unity and standard error (SE) less than %5 of the experimental values.
The three sets of parameters were used for the estimation of pKa, %AA and %DA of a number of hypothetical compounds with structures similar to those considered before but with different substituents as a test of the validity of the derived parameters. The calculated values were within acceptable range compared with other values found in the literature.

Generating Mosaic Images Based On Texture Analysis

Photo-mosaic (mosaic-image) generation is the process of dividing an input image into equal rectangular blocks (image blocks), each of which is replaced with another image (tile image) that matches the features of a corresponding image block. When the produced photo mosaic is seen from a distance, it seemingly forms the input image.
Photo mosaic is not a new concept; however, only a few publications on this subject are available because of its commercial nature. The quality of the produced photo mosaic depends on the size of the database and the variety of images. In addition to process time, a bottleneck occurs because of the discrepancy in the match rate between the input image and the produced photo mosaic.
This research proposes three intelligence-based approaches for producing photo mosaics in less time: (1) k-means clustering with Manhattan distance, (2) back propagation neural network with Manhattan distance, and (3) hybrid fuzzy logic with Elman neural network.
Three groups of features are extracted and then used to find the best matching tile image for each corresponding image block within the container image. The first group comprises statistical features extracted from a 64-gray level quantized histogram. These features are variance, mean, skewness, kurtosis, and energy. The second group is a subset of Tamura features, namely, coarseness, contrast, and directionality. The last group includes a feature called edge rate, which is computed as the percentage of edge pixels within an image that can be detected using a Canny filter. In addition, two methods of color correction are used to adjust the colors of a tile image to match the colors of a corresponding image block. The first method is based on mean, whereas the second is based on histogram specification.
Finally, experimental results show that hybrid fuzzy logic with Elman neural network is the best among the three approaches used. This technique needs 10.0 seconds to produce photo mosaics, with a correlation rate of 0.82 between the container image and the produced photo mosaics,using mean-based color correction. By contrast, this approach needs 42.33 seconds to produce photo mosaics, with a correlation rate of 0.86, using histogram specification-based color correction.

The following open problem stated that, if T: A⟶B is a dense range homomorphism between Banach algebras A and B such that B is semi-simple. Is T automatically continuous? (see [1]).
In [3] given a partial solution of the above problem as follows:
Let A and B be Fréchet algebras such that B is semi simple, the spectral radius rB is continuous on B and the spectral radius rA is continuous at zero. If T : A ⟶ B is a dense range homomorphism, then T is automatically continuous.
In this paper, we prove the following result :
If T : A+ ⟶ B+ is a dense range homomorphism between Jordan – Banach algebras A+ and B+ such that B+ is semi simple, the spectral radius rB+ is continuous on B+ and the spectral rA+ is continuous at zero, then T is automatically continuous.

Magnetically treated water was used for the determination of the physiomechanical properties (setting time, water/powder ratio (W/P) and compressive strength) of a local plaster of Paris. The results were compared with that of ordinary, and non-treated water to determine the same properties.
It was found out that through using magnetically treated water, setting time has decreased by an average of (15.3 %); water powder ratio (W/P) has increased by an average of (2.4 %) and compressive strength has decreased by an average of (22.5 %) compared with the results of ordinary water. Thereforemagnetically treated water may be considered as an accelerator for the plaster of Paris rather than a retarder.

 The study included three stages, the first stage is to prepare the monomer (basic unit  Nʹ,N di-Asetil benziden) and the second stage is preparing the polyamide and third stage  is doping the polymer single doping by acidic solutions H2SO4, HCl with concentrations (0.25 , 0.5 , 0.75 , 1) Molar and different metal chlorides with percentages ( 3-20 )%. Then the best doping of acidic solutions (H2SO4) and best doping of metal chlorides (FeCl3)  doped binary doping by mixing with pure polyamide to prepared samples that doped binary doping.
         Current-Voltage (I-V) characteristics were measured to show the conduction mechanism also the electrical conductivity (σ) as a function of temperature within the range (300-360)K and calculate the activation energy (Ea) and studying the optical characteristics represented by ( FT - IR ) for the prepared sample before and after doping to show the binary doping effect on this characteristics as well as comparing between them. The aging effect on the sample which gives the highest electrical conductivity (σ) for three months was studied also.
       The results showed that the electrical conduction mechanism is ohmic  within the low voltage and space charge limited current (SCLC) at high voltage. Also we see that the binary doping affect the electrical conduction mechanism and it is higher than the conduction of pure and primary doping with acidic solutions and metal chlorides . and the activation energy for the binary doping is about ( 0.184)eV which is much  less than the activation energy for  the pure and single doped.
The optical characteristics represented by ( FT - IR ) also showed an obvious change in the beam intensity comparing with pure polyamide, and the doped by acidic solution, the reason referred  to formation an electronic density of the active groups charge transfer complexes. The effect of the time factor of the binary doped we found that the conductivity of the binary doped polyamide increased when we took into consideration the time factor, the conductivity increased in the beginning of the storing then decreased gradually reached to(7.11 ͯ 10-4 S.m-1) the settled along the aging period approximately.
