First mock-up of the CBM STS module based on a new assembly concept
A molecular dynamics model has been developed to investigate the effect of the crystallographic orientation on the material deformation behaviors in nano- indentation/scratching of BCC iron. Two cases with different substrate orientations have been simulated. The orientations along x, y and z direction are [001], [100] and [010] for Case I and [111], [-1-12] and [1-10] for Case II, respectively. Case I and Case II exhibit different deformation patterns in the substrate. During indentation, the pile-up can be observed in Case I, but not in Case II. During scratching the pile-up ahead of the movement of the indenter has been enlarged in Case I, while a chip with the disordered atoms is generated in Case II. It has been found that Case I has both higher hardness and larger coefficient of friction. The ratios of the hardness and the coefficient of friction between cases I and II are nearly 2. The reason is attributed to the different crystallographic orientations used in both cases
The correlation between parental attitude and susceptibility to drug addiction among students
© 2015, Canadian Center of Science and Education. All rights reserved. The susceptibility to drug addiction affects the formation of the students personality. One of the reasons of its appearance is the socialization defects within the family, regrettable attitude of parents to children. The purpose of this article is to identify and investigate the particularities of the parental attitude to the students of the secondary vocational and higher education institutions who have different levels of susceptibility to drug addiction. To analyze the parental attitude two criteria are used in the research: the degree of emotional bond, parents’ attachment to the child (love, acceptance, warmth or emotional rejection and coldness) and the degree of control over his behavior (high—with lots of restrictions and prohibitions; low—the minimum prohibitive tones). They represent three main factors: positive interest vs. hostility, directivity vs. autonomy and inconsistency as a sharp transition from one extreme to another. The research shows that the formation of susceptibility to addiction among the students of the secondary vocational schools is influenced by the particular attitudes of both parents, while university students are mostly affected by their mothers’ attitude. It is found that the particularities of the child-parent relationships in forming susceptibility to addiction affect more the students of the secondary vocational schools than the higher education students. The research data allow to improve the psycho-pedagogical programs aimed at reducing drug addiction susceptibility among students
Plane torsion waves in quadratic gravitational theories
The definition of the Riemann-Cartan space of the plane wave type is given.
The condition under which the torsion plane waves exist is found. It is
expressed in the form of the restriction imposed on the coupling constants of
the 10-parametric quadratic gravitational Lagrangian. In the mathematical
appendix the formula for commutator of the variation operator and Hodge
operator is proved. This formula is applied for the variational procedure when
the gravitational field equations are obtained in terms of the exterior
differential forms.Comment: 3 May 1998. - 11
Mobile technologies in implementation of programs of internal tourism development
Now a days great attention is paid to the programs of the development of domestic tourism, its informational support, the development of new tourist products. But in spite of efforts in this direction, the population of Russia still has not enough information about tourist recreational opportunities of particular regions and in the whole countr
3,5-Bis(4-fluorophenyl)-1-phenyl-4,5-dihydro-1H-pyrazole
In the title compound, C21H16F2N2, the dihedral angle between the fluorophenyl groups is 66.34 (8)°, and the dihedral angle between the envelope-configured pyrazole group (N/N/C/C/C) and the benzene ring is 11.50 (9)°. The dihedral angles between the benzene and the two fluoro-substituted phenyl groups are 77.7 (6) and 16.7 (5)°. Weak C—H⋯π interactions contribute to the stability of the crystal structure

Communicating with people living with dementia who are nonverbal: the creation of Adaptive Interaction
Loss of verbal language production makes people with dementia appear unreachable. We previously presented a case study applying nonverbal communication techniques with a lady with dementia who could no longer speak, which we termed Adaptive Interaction. The current small-n study examines the applicability of Adaptive Interaction as a general tool for uncovering the communication repertoires of non-verbal individuals living with dementia. Communicative responses of 30 interaction sessions were coded and analysed in two conditions: Standard (Baseline) and Adaptive Interaction (Intervention). All participants retained the ability to interact plus a unique communication repertoire comprising a variety of nonverbal components, spanning eye gaze, emotion expression, and movement. In comparison to Baseline sessions, Intervention sessions were characterised by more smiling, looking at ME and imitation behaviour from the people with dementia. These findings allude to the potential of Adaptive Interaction as the basis for interacting with people living with dementia who can no longer speak
Reasoning over Knowledge-based Generation of Situations in Context Spaces to Reduce Food Waste
Abstract. Situation awareness is a key feature of pervasive computing and requires external knowledge to interpret data. Ontology-based reasoning approaches allow for the reuse of predefined knowledge, but do not provide the best reasoning capabilities. To overcome this problem, a hybrid model for situation awareness is developed and presented in this paper, which integrates the Situation Theory Ontology into Context Space Theory for inference. Furthermore, in an effort to rely as much as possible on open IoT messaging standards, a domain-independent framework using the O-MI/O-DF standards for sensor data acquisition is developed. This framework is applied to a smart neighborhood use case to reduce food waste at the consumption stage
