Formation of conscious motivation for physical education classes among pedagogical students with impaired health

The article presents the results of the first stage of research to determine the level of motivation of students of a pedagogical profile with impaired health to physical education classes. It is shown that conscious choice of students of motor activity will not only increase the level of attending physical education classes, but will also increase their interest in them and will provide active participation in the educational process, which will become the basis for the formation of conscious motivation in students with impaired health physical education classes. The results of the questionnaire survey among the first and second year students identified the main issues that need to be addressed in order to significantly improve the educational process of physical education with students with impaired health. These include: Introducing changes to the curriculum and syllabuses in physical education for students with disabilities, namely in its theoretical section. The purpose of theoretical training will be to form students' knowledge of healthy lifestyles, health status, components of physical health: physical development, physical fitness, physical activity, physical performance. This will not only promote the development of the aforementioned components of physical health in physical education classes, independent physical education and sports, while actively pursuing recreation and leisure, but will also significantly contribute to the formation of conscious motivation in them. The educational process of physical education of student youth can be successful only if the achievement of the goal of learning becomes the dominant motive of this pedagogical process, and the main condition for the formation of motivation is the inclusion of students in the corresponding educational activity. According to the results of the survey, most students preferred to play badminton. Badminton is one of the most widespread and versatile forms of realization of physical activity of a person, due to the wide possibilities of individual choice, dosage of exercises, their variety and degree of complexity. Badminton refers to acyclic complex coordination sports. He is characterized by such features as speed of movement, speed of thinking, speed of execution of technical techniques with the maximum reduction of preparatory actions, manifestation of morally strong-willed qualities.

Totally acyclic complexes and locally Gorenstein rings

A commutative noetherian ring with a dualizing complex is Gorenstein if and only if every acyclic complex of injective modules is totally acyclic. We extend this characterization, which is due to Iyengar and Krause, to arbitrary commutative noetherian rings, i.e. we remove the assumption about a dualizing complex. In this context Gorenstein, of course, means locally Gorenstein at every prime.

${\mathcal{B}$-BOUNDED COHOMOLOGY AND APPLICATIONS

A discrete group with word-length (G, L) is [Formula: see text]-isocohomological for a bounding classes [Formula: see text] if the comparison map from [Formula: see text]-bounded cohomology to ordinary cohomology (with coefficients in ℂ) is an isomorphism; it is strongly [Formula: see text]-isocohomological if the same is true with arbitrary coefficients. In this paper we establish some basic conditions guaranteeing strong [Formula: see text]-isocohomologicality. In particular, we show strong [Formula: see text]-isocohomologicality for an FP∞ group G if all of the weighted G-sensitive Dehn functions are [Formula: see text]-bounded. Such groups include all [Formula: see text]-asynchronously combable groups; moreover, the class of such groups is closed under constructions arising from groups acting on an acyclic complex. We also provide examples where the comparison map fails to be injective, as well as surjective, and give an example of a solvable group with quadratic first Dehn function, but exponential second Dehn function. Finally, a relative theory of [Formula: see text]-bounded cohomology of groups with respect to subgroups is introduced. Relative isocohomologicality is determined in terms of a new notion of relative Dehn functions and a relativeFP∞ property for groups with respect to a collection of subgroups. Applications for computing [Formula: see text]-bounded cohomology of groups are given in the context of relatively hyperbolic groups and developable complexes of groups.

Synthesis and Complexation of a Chiral Sexidentate Pendant-Arm Macropolycyclic Polyamino Acid

The reaction of the acyclic complex ion (methyl (SS,SS)-3-[(2�-aminocyclohexyl)amino]-2-[(2�-aminocyclohexyl)-aminomethyl]propionate)copper(II) with formaldehyde and nitroethane in basic solution yields the pendant-arm macrocyclic complex (SS,SS)-(methyl-15-methyl-15-nitro-2,6,13,17-tetraazatricyclo[16.4.0.07,12]docosane-4-carboxylate)copper(ii) ion. Reduction with zinc in hydrochloric acid yields the hydrochloride salt of the pendant-arm macrocycle (SS,SS)-15-amino-15-methyl-2,6,13,17-tetraazatricyclo[16.4.0.07,12]docosane-4-carboxylic acid (1), separated into and isolated as the major trans (1a) and minor cis (1b) isomers. Co-ordination of (1) to several metal ions [CoIII, CrIII, NiII, ZnII, CuII] and comparison with a previously reported analogue without the cyclohexane rings, trans-13-amino-13-methyl-1,4,8,11-tetraazacyclotetradecane-6-carboxylic acid (2a) salt, is described. The [Ni{(1a) – H+}](ClO4) crystallizes in the monoclinic space group P21, a 9.710(2), b 14.442(1), c 10.317(2) Å, β 96.02(2)°. The nickel displays a distorted octahedral geometry, with all four secondary amines coordinated (Ni–N range 2.044(7)–2.063(6) Å), in addition to pendant primary amine (Ni–N, 2.109(6) Å) and carboxylate (Ni–O, 2.100(6) Å) groups. Protonation constants for the trans (1a) and cis (1b) isomers and stability constants of these isomers with the labile metal ions ZnII, CdII, HgII, PbII, MnII, and CoII were determined by potentiometric titrations. The log K values for 1 : 1 complexes show small variations between geometric isomers.
