In recent years, research has been underway to create working bodies of excavation machines that allow digging soil at higher speeds. One these new types are and transport with an inertial bottom discharge rotor. The paper presents the results studies high-speed proposes a method for determining average values energy intensity transportation, proposed equations can be recommended calculating ta...

Objectives. The increased use of unmanned aerial vehicles necessitates the search for jet fuels based on hydrocarbon materials with high energy intensity and physical density. purpose work was to analyze influence various factors mass hydrocarbons. This analysis is required substantiate algorithm locating energy-intensive CnHm structures. Methods. Combustion calculated using additive procedures...

BACKGROUND Guatemala has experienced a substantial increase in overweight and obesity in recent years, yet physical activity patterns and consequent energy expenditure are largely unexplored in this population. METHODS To describe overall physical activity levels (PAL) and activities contributing to daily energy expenditure, we analyzed time spent in daily activities as reported by 985 women ...

Dual-pulse laser-induced breakdown spectroscopy (LIBS) provides improved sensitivity compared to conventional single-pulse LIBS. We used a combination of Nd: yttrium aluminum garnet (YAG) and CO2 lasers to improve the sensitivity of LIBS. Significant emission intensity enhancement is noticed for both excited neutral lines and ionic lines for dual-pulse LIBS compared to single-pulse LIBS. Howeve...
