D on’t tell your high school football coach, but it is possible to have teamwork even if nobody’s in charge. Inside a cell, for example, myosin VI motors work in concert to haul cargoes along the actin cytoskeleton, Sivaramakrishnan and Spudich reveal (1). Instead of providing muscle power, myosin VI is one of the unconventional myosins whose job is intracellular transportation. Researchers hav...

Farming systems for pest control, based on the stimulo-deterrent diversionary strategy or push-pull system, have become an important target for sustainable intensification of food production. A prominent example is push-pull developed in sub-Saharan Africa using a combination of companion plants delivering semiochemicals, as plant secondary metabolites, for smallholder farming cereal production...

In this research, a functionally graded microbeam bonded with piezoelectric layers is analyzed under electric force. Static and dynamic instability due to the electric actuation is studied because of its importance in micro electro mechanical systems, especially in micro switches. In order to prevent pull-in instability, two piezoelectric layers are used as sensor and actuator. A current amplif...

Push-pull technology improves agricultural productivity. However, its long-term effect on biomass carbon and soil organic (SOC) is not yet known. The aims of this study were: to assess the push-pull (1) (2) SOC, considering climatic conditions length time that had been practiced a farm; (3) establish relationship between SOC farms. Aboveground were measured 36 farms in western Kenya, encompassi...

the natural frequency and pull-in instability of clamped-clamped nano-actuators in the presence of a dielectric layer are analyzed. the influence of the presence of casimir force, electrostatic force, fringing field effect, axial force, stretching effects and the size effect are taken into account. the governing equation of the dynamic response of the actuator is transformed in a non-dimensiona...

[1] A sensitivity analysis reveals that large uncertainty exists in estimates of solute retardation factor R made from sorption push-pull tests. A simplified push-pull data interpretation method for estimating instantaneous linear sorption in confined aquifers is developed. The new method is less restrictive in its application than the conventional method that uses an approximate analytical sol...

The load transfer mechanisms of cable bolts differ from those for normal rebar bolts. The cable bolts used in mines are basically steel strands with different constructions depending on the number of wires or elements and the way they are laid. Tendon bolts (rebar and cable) are normally evaluated for their strength and load transfer properties. The tendon strength can be evaluated by the tensi...
