Human resources are the key factors that determine the success of education. The leader is the person most responsible for all the processes of education and teaching that takes place in college. Leaders should strive for alumni of the college of education quality and deserves world amid global and modern. Education leaders not only act as a leader or a manager but also as educators, administrators, supervisors, and citizens should be able to move the campus towards quality education and cooperation among agencies. Today man is facing rapid change arising from the impact of science and liabilities . Especially if it is based on the assumption that all the problems that stem from the application of the concept and an education that stimulates and promotes the progression of science and technology uncontrollable. Islam also emerged among the various issues concerning the education crisis and other problems which urgently demands a solution in the form of the establishment of an educational system that is based on the concept of Islam. One solution is a management solution in education. Aside from the business world, as well as state management organizations have an important role to deliver educational progress. If countries pursue successful management development management education while pursuing successful human child development services through adequate education. The quality of success and education cannot be separated from the contribution of leaders in education itself. It therefore requires a leader who is wise, thoughtful, has a good personality and can direct subordinates to jointly contribute to realizing quality education. .

Since 2020, the entry of Corona virus disease -19 in Indonesia has changed
the order of life in this country. The Corona Virus pandemic has had a
negative impact on Indonesia in various aspects of life. The government
has set restrictions on activities outside the home to minimize the spread of
the virus, but this has actually led to an increase in cases of criminal acts,
especially violence, especially children as victims. The sad thing is that this
case of violence against children is carried out by those closest to them,
namely parents and family. Learning from home and termination of
employment triggers parental emotions that have fatal consequences for
children. cases of violence against children during the pandemic continue
to increase, but the exact number of cases cannot be determined. Many
consider the violence experienced by children as a family matter and does
not need to be interfered with by the authorities. Indonesia has actually
regulated legal protection for children, but in fact it is still being ignored.
The purpose of writing this article is to identify child violence that occurs,
the legal protection provided, as well as any solutions or programs that can
be used to minimize cases of child violence.

Alumina surface was modified by adsorption of an anionic surfactant, sodium sulfate (S.S). Typical S-shaped isotherm of surfactant on alumina was observed. The adsorption of herbicide on alumina and surfactant treated alumina has been investigated.The enhancement in adsorption of herbicide on surfactant treated alumina is observed, which may be attributed to the solubilization of herbicide on surfactant aggregates formed at solid/liquid interface. The effect of pH on adsorption has been studied. The adsorption is greatly influenced by pH of the medium. The applicability of Freundlich equation was tested for equilibrium data. The influence of various factors such as initial concentration, and mass of adsorbent on adsorption was also studied. The batch kinetics has been tested to pseudo second order reaction and rate constants were calculated.

Authors: Khassaf Saleh Issa 
Published: July 2022

In this research ,the effect of cohesive soils ( clay ) and non –cohesive soils sand on equilibrium scour depth was studied .Experiments were carried out on two types of clay and two types of sand as a bed material using an obstruction ( pier ) to create a local scour. The effect of flow velocity and Froude number on scour depth and the occurrence time of equilibrium scour depth were studied . The results show that for the same conditions, the rate of scour in the clayey soils is less than in sandy soils. Also the time required for occurrence of the maximum scour depth ( equilibrium depth ) in clayey soils is more than in sandy soils. Two formulas were found to predict the equilibrium scour depth in terms of Froude number ,the first is for clayey soils and the second for sandy soils .

Published: July 2022

An experimental study on natural convection heat transfer across an eccentric horizontal annulus under the condition of constant surface temperature was carried out. The study included clarifying the effect of eccentricity ratio and the angular position as well as the effect of Raleigh number on the ability of the inner cylinder to heat reject. An experimental set-up was done for this purpose which consists of a cooling water tank and two aluminum cylinders, the outer diameter of the inner cylinder is(26mm), electrically heated from the inside, which represents the heating element, the inner diameter of the outer cylinder is(100mm) which represent cooling element in this set-up. The experimental study showed that the ability of the inner cylinder to transmit heat with free convection is a function to eccentricity ratio and the angular position, as well as Raleigh number, where this ability increases as angular position increases for all eccentricity ratios, while the eccentricity ratio effect depends on the angular position, where the thermal performance for the inner cylinder may be better at the location (δ=180o) for the ratio (ε=0.2), where the maximum enhancement in heat transfer coefficient was recorded as(10%) at this location in comparison with concentric annulus, whilst the location (δ=0o)for the ratio (ε=0.726) was given maximum reduction in heat transfer coefficient for the inner cylinder was recorded as (23%) in comparison with concentric annulus, whilst the coefficient of heat transfer proportional directly with Raleigh number.

Published: July 2022

In this research, Mindlin’s thick plate theory is extended to include orthotropic plates under the effects of externally distributed moments and shearing forces at top and bottom faces of the plate. These shearing forces produce in-plane forces in plates and the extensional effects of these in-plane forces are considered. The transverse sections of the plates have five degrees of freedom. These are the transverse deflection, the two independent rotations of the normal to the middle plane and the two mutually perpendicular membrane displacements. Thus, five expressions of the governing equations for thick orthotropic plates are obtained with the inclusion of the effects of externally distributed moments and applied shearing forces. As an application to the generation of distributed moments and shearing forces, the problems of thick orthotropic plates resting on elastic foundations with both compressional and frictional restraints are investigated. The finite-difference method was used to solve the governing equations. Besides, finite elements are formulated and used. Good agreements are found in the results from both methods of solution.

Published: July 2022

The objective of this work is to study the effect of impact and blast dynamic loading upon concrete plates reinforced with normal deformed steel bars as well as steel or glass fibers. In order to examine the effect of using different volume and weight fractions of s skeletal bars and steel or glass fiber reinforcements on the impact and blast resistance, 24 plates and 24 prisms were manufactured as test specimens. A set consisting 0f 8 plates were tested under high velocity impact using 14.7 caliber bullets with a shooting distance of 63 m. The specimens with 1.5 % steel fiber and two layers of steel mesh (8 mm at 75 mm) have shown resistance to full perforation of the bullet. Improvements to the resistance to spalling, scabbing and crack growth have also been observed. Field blast testing was carried out on a second set of 8 specimens by using a charge of 100 gm located at the center of each specimen. All the plates were 160 mm thick and with had minimum reinforced of 0.75% glass fiber and a single layer of steel mesh (8 mm at 75 mm). Have shown resistance to full perforation of waves and have restricted the number, the width and the growth of cracks. The last set of the remaining 8 plates was subjected to a low speed impact test performed by a falling steel ball. Test results clearly show the significant effect of using steel and glass fiber besides deformed bars to enhance the impact resistance by 400 % and 20 % by using 1.5 % steel fiber and 0.75 % glass fiber resistance .Energy absorption capacity and ductility were also increased by 100 % and 600 % by using 1.5 steel fiber. Chang in compressive strength of about ±6 % and ± (20 – 30 ) % were observed by using 1.5% steel fibers and 0.75% glass fibers respectively. The inclusion of 1.5% steel fibers and 0.75% glass fibers together with deformed steel bars have improved the tensile strength by 200% and 70% respectively.

Review of some documents reflecting the activities of women's and children's public organizations in the 1990s, against the background of the transition from the protection of motherhood and childhood to the protection of women's and children's rights in Russian politics
Authors: Likhodey Elena Maksimovna 
Published: July 2022

The article is an overview of some documents reflecting the activities of two public organizations dealing with women's issues, and one leading activities in the field of children's issues in the 1990s in Russia. The study of documents of public organizations of that period becomes particularly relevant when studying the transition in the country's policy from the protection of motherhood and childhood to the protection of the rights of women and children, since the activities of such organizations reflect the problems that existed in society. Public organizations were often associated with state authorities, political parties or other political associations, as their representatives actively participated in the activities of the former. In this regard, the study of policy formation in this issue is impossible without studying the activities of public organizations. The article, divided into two semantic headings, examines the goals and objectives of public organizations, the agenda of events held by them, resolutions adopted, possible ways to solve public problems that form the vision of the situation by representatives of public organizations. The scientific novelty of the presented article is determined by the fact that in order to write it, the author managed to attract a range of sources stored in the department of non-traditional press of the SPIB of Russia, and to highlight the activities of public organizations in conjunction with the history of the development of some problems in women's and children's issues in Russian politics, reflected in the documents of public organizations. In addition to these sources, periodical press data and memoirs of the participants of the described events, published by themselves, were also used. The conducted research made it possible to make additions to the process of policy formation in the women's and children's issues in the 1990s from the point of view of history. The results of the research can be used in the preparation of courses on the history of Russia, special courses on the history of state and law, when writing textbooks and textbooks.
