We estimate the role of peer effects in technology adoption using data from a randomized distribution of menstrual cups in Nepal. Using individual randomization, we estimate causal effects of peer exposure on adoption. We find strong evidence of peer effects: two months after distribution, one additional friend with access to the menstrual cup increases usage by 18.6 percentage points. Using th...

Phagocytosis is the process by which cells internalize particulate material, and is of central importance to immunity, homeostasis and development. Here, we study the internalization of immunoglobulin G-coated particles in cells transfected with Fcgamma receptors (FcgammaRs) through the formation of an enveloping phagocytic cup. Using confocal microscopy, we precisely track the location of fluo...

Participants tasted two cups of coffee, decided which they preferred, and then rated each coffee. They were told (in lure) that one of the cups contained "eco-friendly" coffee while the other did not, although the two cups contained identical coffee. In Experiments 1 and 3, but not in Experiment 2, the participants were also told which cup contained which type of coffee before they tasted. The ...

Condition-specific competition, wherein competitive superiority varies with the abiotic environment, can determine species' distributions in a spatially heterogeneous environment. We investigated this phenomenon with two competing container-dwelling mosquitoes. We tested the hypothesis that habitat drying alters the outcome of interspecific competition, predicting that the competitive impact of...

The paper deals with an innovative device, enabling multi-point grasp, firm hold and gentle transfer of limp sheets to the sorting buffers, before the feeding of the assembly sections. The design process avails of fully implemented digital mock-ups and runs extended virtual trims, to accomplish the analysis of the prospected fixture dynamical behaviour, as stand-alone device and as integrated e...

purpose : to investigate the impact of socioeconomic factors on presenting severity of glaucoma methods : in a cross-sectional study at farabi eye hospital, and during 12 months study period, 258 patients with newly diagnosed glaucoma were enrolled and socioeconomic status of the patients were evaluated. results : lower socioeconomic score was associated with higher intraocular pressure (r=-0.3...

surface roughness is a significant parameter which determines the efficiency of optical components. surface damages induced by grinding strongly influence the mechanical strength and optical quality of optical glasses. it is meaningful to rapid evaluate the surface roughness through the measurement of different grinding parameters. in this study, a cup diamond wheel (d64) is used in grinding pr...

Abstract In the present research, the behavior of 304L austenitic stainless steel in the deep drawing process has been studied at the room temperature through experimental and finite element simulation method. Magnetic method calibrated by XRD was used to measure induced-martensite. Martensite volume fraction in the various portion of the deep drawn cup under optimum Blank Holder Force (BHF) a...

peltier technology opens new opportunities for specialapplications. in the current project, this technology was appliedto design and fabricate a portable thermoelectric beveragecooler and thermoelectric cup. the simulation and results of theexperiment showed that the common beverage cooler is not asuitable design for ignoring the effect of natural convection incooling. in our thermoelectric cup...
