Exercise is a common component of weight loss strategies, yet exercise programs are associated with surprisingly small changes in body weight [1-4]. This may be due in part to compensatory adaptations, in which calories expended during exercise are counteracted by decreases in other aspects of energy expenditure [1, 5-10]. Here we examined the relationship between a rodent model of voluntary ex...

this research explores the possible benefits to be derived from interactions between wheels, for supporting a greater proportion of applied loads in the shallower soil layers. this creates possibilities for reducing the risk of deep soil compaction. previous research indicated that different interaction modes occurred under simulated wheel arrangements, being mostly dependent upon the spacing b...

A new hexagonal bipyramidal Ni8 cluster is reported and its magnetic behaviour is analyzed. The molecular structure consists of a hexagonal wheel capped by two additional apical Ni(2+) ions. This structure supports ferromagnetic superexchange interactions between adjacent Ni(2+) ions in the wheel and an antiferromagnetic superexchange interaction between the wheel and apical Ni(2+) ions.

The future's wheel: A new class of wheels, based on subphthalocyanine fragments, for future incorporation in functional nanovehicles is reported (see figure). The syntheses of a symmetric wheel, a nitrogen-tagged wheel, and their ethynyl-bridged homodimers are presented. Theoretical calculations and STM imaging demonstrate the advantage of a bowl-shaped structure and the efficiency of the tag f...

The problems of determining dynamic and kinematic parameters of wheel-legged mobile robot were considered in the paper. The numerical computer model of robot was worked out and simulation researches of suspension were completed. The motion of wheel on road with obstacles and walking motion of wheel were analyzed for determining kinematic and dynamic parameters.

Since car manufacturers pursue in the development of environmental -friendly vehicle, the demand for extensive research on stability, controllability, and reliability of electric vehicles (EVs) increases. Electric powered and by-wire control technology allow manufacturers to build independent four -wheel steering of an allwheel drive in-wheel EV. In past research, we investigated the advantages...

Conventional angle sensors can measure only 360°,but passenger car steering wheel turns through +/-720 (a total of 4 complete turns). In this paper we describe iGMR based steering wheel angle sensor implementation which can be used as a rotation sensor to measure +/720°. KeywordSteering Wheel Angle Sensor, IGMR, Angle Sensor, GMR.

The purpose of this paper is to study the behavior of elastic-plastic stresses under severe drag braking. A railway wheel performs three tasks, aiding in trian movement, supporting the car load, and acting as a brake drum. Finite element computer programs are developed for elasto-plastic stress analysis. An attempt is made here to find an improved fillet profile of the wheel with the intention ...
