We investigate fluid transport in random velocity fields with unsteady drift. First, we propose to quantify fluid transport between flow regimes of different characteristic motion, by escape probability and mean residence time. We then develop numerical algorithms to solve for escape probability and mean residence time, which are described by backward Fokker-Planck type partial differential equ...

This research was performed to identify the incidence of deformity of lower extremity and to identify the relationship of the incidence between the deformities. Once the incidences and relationship are found, next purpose was to find the effects of physical characteristics and residence styles on the development of lower extremity deformities. One hundred fifteen males and 108 females participa...

INTRODUCTION AND OBJECTIVE Spinal pain (SP) has become a very common problem in contemporary societies and occurs in adults, youths, and even children. The aim of the study was to determine whether the prevalence and characteristics of SP, as well as the determinants leading to SP in Polish youths, vary depending on the place of residence. The determinants considered were out-of-school physical...

INTRODUCTION: Perception of beauty is influenced by the individual’s geographic, ethnic, cultural, and demographic background. However, objective measurements remain the foundation for aesthetic evaluations. In the quest for to better define “ideal” lip characteristics, this study assumes interdependence between variables such as country of residence, sex, age, occupation, and aesthetic percept...

the informality of possession and lack of security in residence are among the characteristics attributed to the informal settlements, as well as, they are a key to other problems’ solutions. this essay investigates some of the typical cases of iran’s informal settlements, and this intends to find out the possession conditions, as well as, the conditions necessary for the recognition of the ...

Prevention of mother-to-child transmission of HIV was added to standard antenatal care (ANC) in 2000 for Colombians enrolled in the two national health insurance schemes, the 'subsidized regime' (covering poor citizens) and the 'contributory regime' (covering salaried citizens with incomes above the poverty threshold), which jointly covered 80% of the total Colombian population as of 2007. This...

OBJECTIVE To investigate the association between altitude of residence and risk of sudden infant death syndrome (SIDS). METHODS A retrospective, case control study in the Tyrol, Austria enrolled 99 infants with SIDS occurring between 1984 and 1994, and 136 randomly selected control cases. Data on pregnancy, delivery, child care practice, and socio-demographic characteristics including altitud...

Constructed wetlands have gained much importance for treating domestic, industrial and agricultural wastes and are considered as an effective secondary or tertiary treatment method. The main characteristics affect the removal efficiency of constructed wetland are the vegetation type, hydraulic residence time and substrate. The aim of the present study is to examine effect of vegetation type on ...

In vivo single molecule tracking has recently developed into a powerful technique for measuring and understanding the transient interactions of transcription factors (TF) with their chromatin response elements. However, this method still lacks a solid foundation for distinguishing between specific and non-specific interactions. To address this issue, we took advantage of the power of molecular ...
