HOW TO GET HIGHER QUALITY SCHOOL PHYSICAL EDUCATION WITH A RETROSPECTIVE ON STANDARDS IN EDUCATION?

There is no improvement in the quality of school physical education without establishing standards in education. Basic problems, questions, and models of effective teaching of physical education (PE) are presented. The goal of this topic is that after the adoption of the standards, the professional public gets to know, prepare, and activate them for their application in practice. Through a comparative analysis of the valid goal and program of physical education for primary education, recommendations for the way of implementation, and characteristics of educational standards for primary education and upbringing, educational goals and tasks are made concrete through student achievements - visible outcomes in behavior and reasoning. This is the answer to the question of how to achieve better effects and increase the quality of physical education, the capacities we have at our disposal. Focus on: competence in skills, knowledge in physical exercise and physical education and evaluation of physical exercise and physical education by students, standards that objectify assessment and grades, make them comparable and provide a basis for developing instruments for self-evaluation. One of the significant contributions to the achievement of teaching in accordance with educational standards is the activation of teachers, students, parents, the school and the local community. Dilemmas were raised in connection with specific problems in the educational field of physical education, and above all the conditions for the implementation of the physical education program, as well as the implementation of teaching content, within the first cycle of basic education, which directly reflect on the possibility of reaching the standard by the end of the mandatory of education.  Article visualizations

A possible engineering and economic framework for implementing demand side participation in frequency regulation at value

In this paper we propose an extension of today's Automatic Generation Control (AGC) to enable the participation of demand in frequency stabilization and regulation. This is in addition to the demand participation in energy markets. We stress that as many intermittent energy resources get deployed, it becomes necessary to account for their fluctuations much the same way as the AGC accounts for load fluctuations at present. We outline both technical and economic approach to implementing AGDC at value. A simple example is used to illustrate proof-of-concept for AGDC. © 2011 IEEE.link_to_subscribed_fulltex

The influence of triangular silver nanoplates on antimicrobial activity and color of cotton fabrics pretreated with chitosan

The effect of cotton fabric pretreatment with biopolymer chitosan (CHT) on deposition of colloidal triangular silver nanoplates was studied. Also, the influence of deposited silver nanoparticles on color and antimicrobial activity of cotton fabrics was evaluated. Characterization of colloidal silver nanoparticles as well as silver nanoparticles deposited on cotton fabrics was performed using electron microscopy (TEM and FESEM), XRD analysis, atomic absorption spectroscopy, UV-Vis absorption, and reflectance spectroscopy. The cotton fabric turned from white to blue color upon deposition of triangular silver nanoplates. Antimicrobial activity of CHT pretreated cotton fabric impregnated with silver nanoparticles was tested against Gram-negative bacteria Escherichia coli, Gram-positive bacteria Staphylococcus aureus, and fungi Candida albicans. Deposited silver nanoparticles imparted excellent antimicrobial properties to cotton fabric. The standard sterilization procedure of cotton fabric for antimicrobial activity testing resulted in color change of the fabric from blue to yellow. This color change is most likely consequence of transformation of triangular silver nanoplates into nanodiscs and/or their agglomeration into spheroids
