Adaptation to new environmental stress is often associated with an alteration of one or more life history parameters. Insecticide resistant populations of insects often have reduced fitness relative to susceptible populations in insecticide free environments. Our previous work showed that three populations of bed bugs, Cimex lectularius L., evolved significantly increased levels of resistance t...

OBJECTIVE To prospectively establish risk factors for hamstring muscle strain injury using magnetic resonance imaging (MRI) to define the diagnosis of posterior thigh injury. METHOD In a prospective cohort study using two elite Australian Rules football clubs, the anthropometric characteristics and past clinical history of 114 athletes were recorded. Players were followed throughout the subse...

Fermentation technology has a long history and low-temperature fermentation now become the focus of research. This paper reviews mechanism application optimization relevant strains. Low-temperature leads to differential expression growth in metabolism genes (PSD1, OPI3, ERG3, LCB3 NTH1). can be applied foods various advantages, such as increasing changes volatile flavor compounds other correspo...

The deformation of inclusions in the steel was affected by thermal history during physical simulation processing. After plain strain compression with a reduction 30 pct, average aspect ratio sample cooled down to 1673 K from semi-solid state 1.89, which significantly higher than 1.29 heated persistently up same temperature. mechanism revealed inclusion transformation.

The determination of the dynamic response titanium alloys is vital for aerospace industrial applications. present research investigates effect strain history and temperature on localization in Ti-6Al-4V grade-5 alloy. experimental campaign was conducted using a Split Hopkinson Tensile Bar (SHTB) equipped with an ultra-highspeed camera. characterization material highly affected once necking occu...
