Use of academic social networks by researchers of Sociology in Mexico

Since the 1980s, Mexico has had the National System of Researchers (SNI), a program that recognizes the prestige and quality of the scientific production of the academics that comprise it. Through this, an economic stimulus is granted according to the level obtained, which can be: candidate, level I, II, III, and emeritus. The main of this work is to analyze how the 125 researchers of level III of the area of Sociology have incorporated the use of science 2.0 tools for the visibility and dissemination of their scientific production, from the creation and updating of academic profiles in Google Scholar and on two academic social networks: ResearchGate, and Academia.edu. For this, regardless of the particular indicators of each of these platforms, we review: level of update of the profile; type of documents deposited; number of downloads, cites and visits to their profile.

Features of t teleroentgenographic parameters of the upper and lower jaws in Ukrainian young men and young women with orthognathic occlusion and with different types and profiles of the face according to Schwarz A. M.

Numerous studies have shown that teleroentgenographic indicators differ in people of different races, ethnicities, different populations, inhabitants of different geographical areas and often differ from the values of such indicators described by the authors of classical methods of cephalometric analysis. The aim of the study was to establish teleroentgenographic parameters that can be most often corrected during orthodontic and surgical interventions and to determine their features in Ukrainian young men and young women with orthognathic occlusion depending on profiles and facial types according to Schwarz A. M. The results of studies of lateral teleroentgenogram of the head of 49 young men aged 17 to 21 years and 76 young women aged 16 to 20 years with a physiological bite as close as possible to orthognathic using dental cone-beam tomography Veraviewepocs 3D Morita (Japan) are presented in this work. The morphometric teleroentgenographic parameters of the upper and lower jaws and inter-jaw parameters, which can most often change during surgical, orthodontic, cosmetic interventions in groups of persons with different profiles or types of faces according to Schwarz A. M., were determined. All significant differences between groups of young men with different facial profiles and between groups of young women with different facial profiles are of the same type: in both young men and young women with the first type of face profile – angle B is greater than in representatives with the third profile type, and angle MM is greater than in representatives with the third and second profile types; both in young men and young women with a second face type profile – distance R.asc. larger than the representatives with the first profile type; in both young men and young women with the third face profile type, the angle F is larger than in the representatives with the first profile type, the angle I is larger than in the representatives with the first and second profiles type, and the distances L-Mand and R.asc. larger than the representatives with the first profile type; the angle T have greater values in young men or young women with the first profile type of the face than with the second and third profiles type and have greater values in the representatives with the second profile type than with the first type profile of the face. Another picture is observed in the analysis of indicators in young men and young women with different face types. Thus, in persons with the third type of face the distance Max is greater than in persons with the first type and with the second type of face; the angle F in young men or young women with the third type of face is greater than in representatives with the second and first types, and in representatives with the second type – greater than in young men or young women with the first type of face. Young men with the first type of face have higher values of angles G, B and T than young men with the third type and angle B than young men with the second type of face; in young men with the second type of face – greater values of angle I than in young men with the first type and angle B than in young men with the third type of face; young men with the third type of face have larger values of angle I and distance R.asc. than young men with the first type of face. In young women, only tendencies to higher values of I and T angles were recorded in persons with the third type of face than with the first type. The obtained results indicate the need to divide young men and young women into separate groups according to the profile and type of person for an individualized approach to the definition and analysis of teleroentgenographic indicators in the population of Ukraine.

Multi-Objective Optimization of Modified Cycloidal-Toothed Gerotor Pumps by Genetic Algorithm

Cycloidal-toothed gerotors are formed by the combination of epicycloid and a hypocyloid arcs that use the pitch circles as their base circles. They are a common profile type used in industry likely because they can be generated by simple parametric equations. One of the problems with the cycloidal-toothed profile type is that the radius of curvature of both the inner and outer gear are zero when the gears contact at the pitch point which can lead to high contact stress. A gear generation algorithm has been developed that modifies the hypocycloid tooth form to eliminate contact in regions with very low radii of curvature that is yet to be described in scientific literature. Seven performance metrics are developed to evaluate size, flow ripple, adhesive wear, contact stress, radial gap leakage, lateral gap leakage, and inlet throttling that are used as objective functions in a multi-objective optimization. The pump geometry is optimized by applying the NSGA-II algorithm with a population size of 1000 for 500 generations to produce a pareto front, and the results are compared to two cycloidal-toothed gerotors used in the automotive industry. Two designs were found that significantly reduce the contact stress in the profiles while giving the same performance in the other six objective functions in comparison to the profiles used in industry. Another two designs are found that can significantly reduce several objective functions if the size of the pump can be increased slightly.

PENILAIAN KINERJA TRIPLE BOTTOM LINE PERUSAHAAN HIGH PROFILE DAN LOW PROFILE YANG LIST DI BEI

This research is conducted with the aim of analyzing the performance of companies in Indonesia if measured by Triple Bottom Line and testing whether companies with high environmental risk (high profile type) have different performance with companies with low environmental risk (low profile type). Triple Bottom Line performance is measured by the GRI-G4 Index. The data were obtained from companies listed on the Indonesia Stock Exchange in 2017 and the research sample was conducted with purposive technique and obtained 42 companies. Data is obtained by downloading Financial reports and CSR Report at www.idx.co.id. Data analysis was done by descriptive statistic and Independent Sample T Test. The results showed that performance based on Triple Bottom Line in Indonesia in 2017 was low (24%). Whereas, if observed on performance differences in companies with high profile type with low profile type, profit performance measured by economic aspects and the performance of planets measured by environmental aspects is unlikely. While the performance of people measured by social aspect shows difference between high profile company and low profile.

AEOLIAN SEDIMENT TRANSPORT AT A MAN-MADE DUNE SYSTEM; BUILDING WITH NATURE AT THE HONDSBOSSCHE DUNES

This paper presents the influence of aeolian sediment transport on the initial morphological evolution of beach and dunes at the man-made dune system ‘Hondsbossche Dunes’ at the Dutch coast. In total 35 million m^3 dredged material was used for the construction of a beach, dune and foreshore system. This study focused on differences in morphological response within the five different realized dune profile types. A conceptual framework was developed, based on the assessment of (1) environmental forcing, (2) sediment supply from aeolian and marine sources and (3) dune types. These three components were quantified from an analysis of measured profile evolution and the application of an aeolian sediment transport model for the first 19 months since the project delivery date in May 2015. Morphological changes were most pronounced in the first seven months after construction. Dune growth of a profile type at this location is determined by a temporal and alongshore variability in local processes that determines the aeolian sediment supply towards the dunes and the dune geometry that determines the capacity of the profile type to capture the sediments. The model simulations managed to qualitatively reproduce alongshore variations in dune growth as a result of spatial variations in sediment availability, grain size, profile shape and interaction with vegetation. Overall, this study shows the relevance of both marine and aeolian processes in such man-made dynamic systems that are comparable to natural systems. Continuing the monitoring and modelling of this system will improve the quantitative knowledge for design optimization of the Building with Nature philosophy.

Construction of Shale Gas Well

The paper describes shale gas borehole axes trajectories (vertical, horizontal, multilateral). The methodology of trajectory design in a two-and three-dimensional space has been developed. The selection of the profile type of the trajectory axes of the directional borehole depends on the technical and technological possibilities of its implementation and the results of a comprehensive economic analysis of the availability and development of the field. The work assumes the possibility of a multivariate design of trajectories depending on the accepted (available or imposed) input data.
