Qualitative Consideration

This article examines the link between Serbia’s demographic and socioeconomic momentum on the one hand, and the migration phenomenon on the other. This is done both to determine the restrictions for development and to identify the potential scope for using migration as a catalyst of Serbia’s development as an emigration country. The revised push and pull model by Fassmann and Musil (2013) and the migration transition model (from emigration to immigration countries), developed by Fassmann and Reeger (2012) have been chosen as the article’s theoretical frame of reference. The emphasis in the article is on qualitative consideration of these topics, but one that is based on various types of records. To that end, the author has used statistics and the findings of various national studies conducted in the recent years.

Qualitative Consideration

The practical aim of the research is to develop a methodology for assessing the functional state of the musculoskeletal system in the case of complex human pathologies and associated injuries with the objective distinction of interdependent anatomical and functional disorders in the osteoarticular system, nervous and muscular subsystems, identification pathology severity in the separate subsystems and the degree of influence for each of them on the movement organization as a whole. In patients with cerebral palsy the neurological movement disturbance is a priority component, differentiation of which may by difficult due to lack of tools to evaluate objectively and display the features of functioning nervous system in normal and pathological conditions. The authors propose a set of interval indicators of stabilometric study and method to use it providing the more qualitative consideration individual characteristics and the formation of clinically interpretable representation of a visual results image as compared with the standard vector and frequency indicators.

Qualitative Consideration

SummaryA method is presented for the calculation of the streamwise component of vorticity, for flows in rotating passages. The method may be regarded as an extension of the methods applied in recent years to the calculation of secondary flows in stationary passages.Attention is concentrated on the quantityI=p+½ρV2−½ρU2,whereVis the fluid velocity relative to the rotor andUis the rotor tangential velocity.Iremains constant along a streamline in the rotor, and is found to enter into the equation for the generation of vorticity in much the same way as the total head enters for flow in stationary passages.An approximate calculation of the streamwise vorticity generated in a simple axial-flow rotor is made, and qualitative consideration is given to the flow in a centrifugal impeller. Just as for the calculation of secondary flows in stationary passages, an approximate shape of the streamline must be assumed before the secondary flows can be calculated.
