Catchment area, environmental variables and habitat type as predictors of the distribution and abundance of Portulaca oleracea L. in the riparian areas of Serbia

Portulaca oleracea L.is one of the most widely distributed plant species, invading a host of worldwide regions.Rivers and canals, as corridors connecting neighboring habitats, are known to exhibit high invasion levels.Consequently, the aim of this paper was to show which catchment areas, environmental factors and habitat types can be seen as predic

Functional Identification of Px-fringe and Px-engrailed Genes under Heat Stress in Chlorpyrifos-Resistant and -Susceptible Plutela xylostella (Lepidoptera: Plutellidae)

In our previous research, the fitness cost of resistance of the diamondback moth (DBM), Plutella xylostella found in insecticide-resistant DBM (Rc-DBM) under heat stress was based on heavier damage to wing veins when compared to insecticide-susceptible DBM (Sm-DBM).To investigate the molecular mechanism of the damage to the veins between Rc- and Sm

Can microprocessor knees reduce the disparity in trips and falls risks between above and below knee prosthesis users?

While all lower limb prosthesis walkers have a high risk of tripping and/or falling, above PROTECTING CREAM knee prosthesis users are reported to fall more frequently.Recognising this, engineers designed microprocessor knees (MPK) to help mitigate these risks, but to what extent these devices reduce this disparity between above and below knee users

Retrodirective Antenna for Inter-Satellite Data Transmission

A new X-band retrodirective antenna based on superheterodyne mixer and phase conjugating technology is proposed for inter-satellite data transmission in this paper.The novel phase conjugating circuit, utilizing the reciprocity of the passive mixers, achieves high RF-IF and LO-IF isolations, high communication link gain, and a very compact low profi
