In addition, the consistent results obtained using different methodologies demonstrate that the presented force-probing assays and the theoretical model can serve a combined testbed to investigate nanoscale mechanics of the living cell membrane.Photoluminescence (PL) was used to estimate the concentration of carbon in GaN grown by hydride vapor phase epitaxy (HVPE). The PL data were compared with profiles of the impurities obtained from secondary ion mass spectrometry (SIMS) measurements. Comparison of PL and SIMS data has revealed that apparently high concentrations of C and O at depths up to 1 µm in SIMS profiles do not represent depth distributions of these species in the GaN matrix but are rather caused by post-growth surface contamination and knocking-in impurity species from the surface. In particular, PL analysis supplemented by reactive ion etching up to the depth of 400 nm indicates that the concentration of carbon in nitrogen sites is below 2-5 × 1015 cm-3 at any depth of GaN samples grown by HVPE. We demonstrate that PL is a very sensitive and reliable tool to determine the concentrations of impurities in the GaN matrix.The aim of this review was to conduct a meta-analysis to assess the effectiveness of behavioural interventions to reduce HIV-related risk behaviours among key populations people who inject drugs, female sex workers, men who have sex with men and transgender in Nepal over the last two decades. Using four electronic databases, we performed a systematic search of the literature on HIV interventions implemented in Nepal and published from January 2001 to December 2016. In addition, grey literature was also scrutinised for potential articles. The search focussed specifically on behavioural interventions (peer education and HIV testing se
