Conventional hypergolic propellant combinations, using hydrazine and its derivatives as fuels dinitrogen tetroxide based oxidizers, have been applied in spacecraft for attitude roll control systems more than 50 years. However, due to their high toxicity carcinogenic potential, investigations into alternative green propellants are an active field current research efforts. Promising candidates co...

The dripping faucet experiment seeks to provide a relatively simple visualization of a system that exhibits seemingly predictable dynamics that quickly transitions to an entirely unpredictable, chaotic behavior under certain conditions. This behavior is first modeled through equations determine from previosu research and papers in order to understand the general phenomenon and established a bas...

BACKGROUND In previous pilot studies we have demonstrated that the Treatment Motivation and Readiness Test (TRE-MORE) is capable of predicting the outcome of obesity therapy and that a higher muscle mass (MM) is associated with a greater weight loss. Purposes of the present study were: to confirm the predictive value of TRE-MORE scores and MM, using a standardized non-pharmacologic intervention...

OBJECTIVE To explore factors influencing participation and attrition in a family-led weight-management programme for obese Pacific children. DESIGN Qualitative study used bilingual in-depth interviews at exit and end of an 8-week weight-management programme. SETTING New Zealand. SUBJECTS Forty-two parents/primary caregivers of obese children who were randomised in the intervention weight-...

This paper presents an experimental investigation of the effect impact force on residual strength capacity simply supported reactive powder slabs. Eight specimens reinforced concrete slabs with dimensions 500 x mm and 70 in four categories were used. The influences slab compressive (conventional concrete), steel fiber proportion (1, 1.5, 2%), percentage reinforcement tension zone (ρ1=0.007, ρ2=...
