BACKGROUND Expedited partner therapy (EPT), the practice of treating the sex partners of persons with sexually transmitted infections without their medical evaluation, increases partner treatment and decreases gonorrhea and chlamydia reinfection rates. We conducted a stepped-wedge, community-level randomized trial to determine whether a public health intervention promoting EPT could increase it...

Pt-doping of an ultrathin Pd nanosheet results in the unprecedented structural rearrangement of a Pd nanosheet into a PdPt nanotent structure, in which a tripod stands on a triangular nanosheet. Further growth of Pt phase on this nanotent structure is dependent on the presence of surface-stabilizing CO molecules, leading to the formation of two distinct nanoscale phase segregated structures wit...

Due to its environmentally benign character, supercritical carbon dioxide (scCO2) is considered in green chemistry, as a substitute for organic solvents in chemical reactions. In this paper, an innovative approach for preparation of flame retardant cotton fabric was obtained by utilizing supercritical carbon dioxide with co-solvent. A novel phosphorusnitrogen containing piperazine derivative, t...

With the accelerating process of urbanization, developing countries are facing growing pressure to pursue energy savings and emission reductions, especially in urban passenger transport. In this paper, we built a Beijing urban passenger transport carbon model, including an economy subsystem, population subsystem, transport subsystem, and energy consumption and CO2 emissions subsystem using Syst...

By the application of an ultra fast magnetic field sweeping (2.0 × 105 T/sec) and the zero-field magnetic resonance (ZFMR)/FID techniques, we are able to probe the dynamics at the level anti-crossing region of the photo-excited triplet states of pentacene-h14 in p-terphenyl (PHPT) and pentacene-d14 in p-terphenyl (PDPT) systems. The crossing is a non-adiabatic passage at such a high jumping rat...

Lipids comprise a significant, highly plastic proportion of the biomass in haptophytes, ubiquitous, globally and genetically diverse clade photosynthetic microalgae. Recent studies have investigated cellular lipidomes disparate, individual species haptophytes under nutrient-replete nutrient-limited conditions, but not how vary across larger evolutionary or its ecological functional groups. We c...

People life is today surrounded by a digital world environment which enables to interact with user and to react on user needs not only after user’s requests, but also before the user needs grow. Paper deals with a concept of User Adaptive System (UAS) with two areas of user context along with reaction on them. A Predictive Data Push Technology (PDPT) Framework concept is mentioned as a possible...
