Abstract Background Despite the numerous policy interventions targeted at preventing early age at first childbirth globally, the prevalence of adolescent childbirth remains high.Meanwhile, skilled birth attendance is considered essential in preventing childbirth-related complications and deaths among adolescent mothers.Therefore, we estimated the p

It is of great significance for ecological environment protection to clarify the regional evolution characteristics of shallow water under the disturbance of multi-working face mining.In this paper, the catastrophe theory method, GIS spatial analysis function and FEFLOW numerical calculation method were comprehensively used to study the instability

n this study, a batch Accessories least square estimator that utilizes optical observation data is developed and utilized to determine geostationary orbits (GEO).Through numerical simulations, the effects of error sources, such as clock errors, measurement noise, and the a priori state error, are analyzed.The actual optical tracking data of a GEO s

Objectives: The objective of this study was to identify naturally occurring typologies of Faroese adolescents on the basis of Push-Pull MIG Gun their exposure to traumatic and negative life events.It was hypothesized that underlying typologies of trauma and negative life events would be uncovered.Furthermore, it was hypothesized that males would be
