This paper presents the dynamics of microbubbles that are pinched-off and breakup in micro-jetting. A microjet is generated in two bubble interaction when a laser induced bubble is impacting a static gas bubble in a microchannel. Gas layers with a height of hundreds of nanometer are pinched off from the accelerated gas bubble wall during the jetting process. They are further modified by surface...

We study the orbital stability and instability of single-spike bound states of critical semi-classical nonlinear Schrödinger equations (NLS) with linear and nonlinear lattices. These equations may model an inhomogeneous Bose-Einstein condensate and an optical beam in a nonlinear lattice. When the linear lattice is switched off, we derive the asymptotic expansion formulas and obtain necessary co...

We study the crack-front fingering instability of an elastic adhesive tape that is peeled off a solid substrate. Our analysis is based on an energy approach using fracture mechanics and scaling laws and provides simple physical explanations for (i) the fact that the wavelength depends only on the thickness of the adhesive film and (ii) the threshold of the instability, and (iii) additionally es...

this paper presents a model of a catchment area in northwest of iran. the researchers have studied ajichai basin which is located in the east part of orumiyeh lake, located at the longitude of 47 52’ e to 45 32’ e and the latitude of 37 26’ n to 38 30’ n. the researchers have chosen the data from tabriz upper air station which is the only one in the area. the research data are seven instability...

Abstract Floatplane is a type of airplane that can take-off and land on the surface water, for it equipped with float installed under fuselage to serve buoyancy force. An important phenomenon often occurs should be avoided during operation porpoising because causes longitudinal instability which has an impact passenger safety comfort. This paper describes mechanism variables influence occurrenc...

OBJECTIVES Ankle injuries account for the highest percentage of injuries in netball, yet the chronic nature of ankle sprains is under reported within this population group. Chronic ankle instability is a term used to describe certain insufficiencies that persist after an acute ankle sprain. The aim of this study was to investigate recurrent sprain, perceived ankle instability and mechanical ank...

This paper explores the potential impacts of introducing real economic incentives in Choice Experiments (CE). While many others have investigated such impacts before, the majority of the literature has focused solely on mitigation of hypothetical bias. We contribute to this literature by widening the scope of research to other behavioural aspects where consumers in CE are often found to deviate...
