Prevailing Educational Philosophy among Secondary School Teachers at Irbid Governorate Schools from their Point of View

This study aimed to identify the prevailing educational philosophy among secondary school teachers at Irbid Governorate Schools from their point of  view. The study was conducted on a sample that consisted of 215 male and female teachers from the first Directorate of Education of Irbid by using a questionnaire consisting of 60 items that represent the pragmatism, Islamic, existential, ideal and realistic philosophies. The study found that the level of having philosophical beliefs among secondary school teachers was intermediate; and that the Islamic philosophy was ranked first followed by pragmatism, idealism, realism, and existentialism respectively. The results of the study showed that there were no statistically significant differences due to the study variables (sex and major) on the studied instrument as a whole or on the interaction between them. In addition, there were no statistically significant differences due to the variables on the fields of study separately, and on the interaction between them, except the field of ideal philosophy on the variable of major in favor of literary stream

Inheritance of Ten Characters in Barley Crosses

Inheritance of many characters in barley has been studied, and two or more genes have been located in each of the seven pairs of chromosomes. Studies of the mode of inheritance of these characters will aid plant breeders materially in working with plants of diverse genetic make-up. Hybridization followed by selection and testing can improve present varieties by replacing them with new ones having more desirable characters. Barley (Hordeum sp._ is one of the few species of plants widely distributed which is well adapted to genetical analysis. This plant has a lower number of chromosomes, complete self fertility, and a wealth of easily classifiable, hereditary characters. This study represents the data obtained in an investigation of ten characters in barley in the F2 and F3 generations. The nature of the inheritance, genes involved, and possible linkages have been determined

The Effects of Head Pose and Face Roundness on Age Progression in Children Faces

Background: This paper analyzes the geometric changes in human face during childhood to estimate the related age; cranial changes are used as age-progression features within childhood stage (0-12) years. Infant face is close to the circular shape turning to an ellipse shape over age progression face oval is determined and drawn using face landmarks, were it’s robust against opening mouth, thinness, fatness or face occlusion by hair. Materials and Methods: The experiments depending on two types of face dataset. First one is the standard FG-NET dataset, which was provided with face landmark points numbered from 1 to 68 [14, 15]. Besides, an Internet-based collected data set of (3010) face images extracted from Daily Photo Project. Results: Drawn face ellipse provided set of measures that significantly modeled changes in forehead size and face roundness. Studied age period was between birth and 12 years old. Exaggerated head size at birth provides round face with big forehead, which starts shrinking as age progresses natural face. Conclusion: Face ellipse provided efficient measures and distances to represent face changes along childhood. Comparing with published researches in young-face age estimation, proposed face ellipse recorded encouraging results. &nbsp

Effect of vincristine and vinblastine on mice spermatozoa in vitro

The aim of this project was to study the in vitro effect of antineoplastic drugs (vincristine and vinblastine) on mice spermatozoa. Eighteen adult (age 8-9 weeks) male mice were divided into three groups equally. The animals in each group were slain by cervical dislocation, the testes were removed and two tails of epididymides isolated. Spermatozoa were obtained from the two tails of epididymides by mincing in 500 µl TCM-199.The first group non-treated (unadded) as a control group, second group added 10 µg/ml of vincristine to TCM-199 and the third group added 10 µg/ml of vinblastine to TCM-199. After 10 minutes from added of vincristine and vinblastin measured the following test: spermatozoa activity, percentage dead spermatozoa and morphological abnormalities of spermatozoa. The obtained results indicated that vincristine and vainblastine showed significant reduction in activity, while increased in percentage of dead/live spermatozoa and morphological abnormalities of spermatozoa compared with the control group. Moreover, the data showed that vincristine and vinblastin had effect on spermatozoa in vitro

Using Lognormal Function to Measure Negative Chromatic Dispersion of Broadband Photonic Crystal Fiber

Negative chromatic dispersion curves in a highly dispersive dual-concentric core pure silica photonic crystal fiber (PCF) have been investigated and measured. Our investigation depends on a simulation process for previous experimental results that were obtained by plane wave expansion (PWE) method. In the presented simulation process an approximation function will be considered to create a mathematical model that enables us to measure chromatic dispersion curves in this typical type of PC.The variations in the  dispersion band-width that product as a function of lattice constant variation and air- holes diameters of lattice structure were carefully observed using Log normal approximation function. The obtained results by lognormal function match well with these obtained by PWE This work is devoted to supply fibers manufacturers with a précised  model that can evaluate PCF performance by measuring negative dispersion and dispersion band-width theoretically and accurately. Keywords: Chromatic dispersion, Photonic crystal fiber, lognormal function, Lattice structure parameters

Assessment of the Buckling Behavior of Square Composite Plates with Circular Cutout Subjected to In-Plane Shear

This paper aims at evaluating the effect of various parameters on the buckling load of square cross-ply laminated plates with circular cutouts. The parameters considered in this study are: (1) cutout size (2) cutout location (3) fiber orientation angle and (4) type of loading. Three types of in-plane loading were considered; namely, uniaxial compression, biaxial compression and shear loading. The reduction in the buckling load due to the increase of cutout size was significant in the case for shear loading as compared to uniaxial and biaxial compression. For relatively small size cutouts, a better performance was achieved if the cutout is kept close to the edge of the plate, however, for relatively large size cutouts, a higher buckling load is achieved if the cutout is kept in the middle of the plate. Several other imperative findings based upon the various parameters are also presented in this study

A hybrid algorithm for voltage stability enhancement of distribution systems

This paper presents a hybrid algorithm by applying a hybrid firefly and particle swarm optimization algorithm (HFPSO) to determine the optimal sizing of distributed generation (DG) and distribution static compensator (D-STATCOM) device. A multi-objective function is employed to enhance the voltage stability, voltage profile, and minimize the total power loss of the radial distribution system (RDS). Firstly, the voltage stability index (VSI) is applied to locate the optimal location of DG and D-STATCOM respectively. Secondly, to overcome the sup-optimal operation of existing algorithms, the HFPSO algorithm is utilized to determine the optimal size of both DG and D-STATCOM. Verification of the proposed algorithm has achieved on the standard IEEE 33-bus and Iraqi 65-bus radial distribution systems through simulation using MATLAB. Comprehensive simulation results of four different cases show that the proposed HFPSO demonstrates significant improvements over other existing algorithms in supporting voltage stability and loss reduction in distribution networks. Furthermore, comparisons have achieved to demonstrate the superiority of HFPSO algorithms over other techniques due to its ability to determine the global optimum solution by easy way and speed converge feature
