OBJECTIVES Given the burden associated with vehicle-related trauma, there is interest in time and cost effective methods of providing information to assist recovery. This systematic review aims to address the question: "Do targeted early information interventions improve outcomes following vehicle--related injuries for persons of working age?" DATA SOURCES Ovid Medline, EMBASE, PsychINFO and ...

in this paper we propose and simulate a new heterostructure mesfet, called δ-doped ldd hmesfet. to improve carrier velocity in vicinity of the source in channel of gaas mesfet, one can replace source with alxga 1-x as. by increasing al content, discontinuity of hetero-interface could be increased. therefore, the velocity increases in the low field. however, increasing al mole fraction in excess...

the present study sought to investigate the acquisition of referential, quasi and expletive subject pronouns, three different types of obligatory subjects in english, by adult persian speaking l2 learners of english at different stages of l2 acquisition. a grammaticality judgment test and a translation test were designed and developed to elicit the participants' knowledge of obligatory subjects...

The utilization of Pd nanoparticles stabilized by aggregates of hetero-oligophenylene derivative 3 as an excellent catalyst in a copper/amine free Sonogashira coupling reaction under aerial conditions at room temperature has been demonstrated.

A DNA duplex was used as a scaffold to evaluate the intrinsic reactivity of [2 + 2] photodimerization between stilbene derivatives; the duplex pre-organizes the substrates avoiding the need for an association step. Unmodified stilbenes were first introduced at base-pairing positions on complementary DNA strands. The duplex was then irradiated with 340 nm UV light. HPLC analyses revealed that [2...
