Shababa A. Bahjat; Adeeba younis Sherif; Musa’ab Hani Salih

JOURNAL OF EDUCATION AND SCIENCE, Volume 26, Issue 1, Pages 22-31
DOI: 10.33899/edusj.2013.89666

Abstract
Biodeterioration of paper and parchment in ancient books and documents represents a cause of great concern for libraries and archives all over the world. The degradation processes occurring in paper, typically occur over extended timescales (~20 to >200 years). The study of the mechanisms underlying the microbiological attack of historical materials has been widely practiced and still represents one of the main focuses of those institutions and laboratories that are involved in cultural heritage conservation.
A total of seventy historical manuscripts stored in different public and personal libraries were sampled for isolation and characterization of cellulolytic bacteria. The age of the manuscripts varied from 170-1030 years old. The characterization of the bacterial isolates was based on colony morphology, biochemical test and their ability to hydrolyze cellulose.
Fourty nine bacterial isolates including 46 gram positive rods and 3 gram positive cocci were purified for further characterization. Fourty six gram positive isolates were sporeformers belonging to the genus Bacillus. Iodine solution was used to detect cellulolytic activity on CMC agar.. Results have shown that 16% of the isolates were weak producers, 53% moderate, 21% high and 10% v. high producers.

Keywords: cellulolytic bacteria, historic documents,paper, deterioration.

Mechanical Properties of Low Density Polyethylene / Citrus Aurantium Shell Composite

Hamed A. Hamde

JOURNAL OF EDUCATION AND SCIENCE, Volume 26, Issue 1, Pages 32-39
DOI: 10.33899/edusj.2013.89645

Abstract:
Mechanical properties of (LDPE-463)/Citrus Aurantium shell composite are assessed with respect to the effect of Citrus aurantium shell content varying from 2.5% to 50%. An obvious decrease in the mechanical parameters is recorded after adding Citrus aurantium shell of a high weight ratio. The mechanical properties of loaded film have been evaluated through several parameters concerning the elastic deformation based on measuring the load – elongation characteristics. The melt index is found to be increased up to 56.5 with increasing the filler concentration up to 50%, while the incorporation of the filler has adversely affected mechanical properties by reducing the tensile at yield and break, impact and elongation. This reduction is due to two reasons poor interaction between filler particles and LDPE chains and low molecular weight of the short molecular chains of the composite thus resulting in a lower tensile strength and elongation at yield and break and may be related to particles/matrix interface which depends on the properties of both the filler and the host polymer. Finally the filler contributes to reducing the cost due to the change made in melt index, viscosity and the reducing of LDPE in the composite matrix.

JOURNAL OF EDUCATION AND SCIENCE, Volume 26, Issue 1, Pages 57-66
DOI: 10.33899/edusj.2013.89663

Abstract
Polarization Mode Dispersion (PMD) plays a great role in high bit rate optical communication systems. This factor had been studied thoroughly in this article of optical layout simulation by (OptiSystem7.0). This simulation had revealed some interesting features of (PMD) relating its major parameters, i.e, (PMD coefficient(DPMD)), mean scattering section, and scattering section dispersion). An optimum values have found for the mentioned parameters were: DPMD= 2, mean scattering section=150, scattering section dispersion=110.
The opportunity to study the influence of PMD on high bit rate network can be of a substantial benefits to engineer the optical communication network.

ABSTRACT
A fuzzy logic model was constructed to classify the d.c glow discharge regions (Townsend dark region, glow discharge region, arc discharge) which including the design of computerized fuzzy inference system that depends on one of the intelligent techniques (Fuzzy logic). Their input consists of linguistic variables describing the fundamental parameters (current, voltage) of standard (I-V) curve of electrical discharge, and their output consists of three linguistic variables(dark, glow, arc) that describe the d.c. electrical discharge regions. It is suggested in this study that three different types of Gaussian membership functions in different forms for each variable. The results seem to be a good compatible with other published researches, making use of the MATLAB scientific software version 7.6.0.324 (R2008a

JOURNAL OF EDUCATION AND SCIENCE, Volume 26, Issue 1, Pages 149-161
DOI: 10.33899/edusj.2013.89420

Abstract
This paper deals with finding outliers in a multivariate linear regression model after assuming a model of normal – Wishart distribution. This method is based on the estimation of probability of an outlier for each observation by mixed Bernoulli model with shifting location outlier. We show how to obtain the posterior distribution in the mixed model by Gibbs sampler algorithm. Also the determination of the number of outliers is done by criterion of marginal likelihood distribution. The theoretical results of this research are applied to real data of multivariate linear regression. The results obtained are so encouraging in determining the outliers in these data.
