objective: to evaluate and report the functional results of surgical management of intercondylar fractures of the humerus in adults using a novel dual plating technique. methods: a total number of 60 patients with riseborough and radin type ii, iii, and iv intercondylar humerus fractures were operated with open reduction through a trans-olecranon approach and internal fixation using two plates ...

in this paper, overall heat transfer coefficient and friction factor of water based γ-al2o3 nanofluid in a double tube counter flow heat exchanger have been measured experimentally under turbulent flow condition. for better dispersion of γ-al2o3 nanoparticles in distilled water, magnetic stirrer and ultrasonic vibrator (with a power of 240 kw and frequency of 35 khz) were implemented. the stabi...

a unital $c^*$ -- algebra $mathcal a,$ endowed withthe lie product $[x,y]=xy- yx$ on $mathcal a,$ is called a lie$c^*$ -- algebra. let $mathcal a$ be a lie $c^*$ -- algebra and$g,h:mathcal a to mathcal a$ be $bbb c$ -- linear mappings. a$bbb c$ -- linear mapping $f:mathcal a to mathcal a$ is calleda lie $(g,h)$ -- double derivation if$f([a,b])=[f(a),b]+[a,f(b)]+[g(a),h(b)]+[h(a),g(b)]$ for all ...

abstract determining saturated hydraulic conductivity (ks) is one of the important soil characteristics that its estimation is important in soil and water studies. there are several methods for estimating ks in unsaturated conditions. these methods include the inversed-auger-hole method, the double-ring infiltrometer and the single-ring pressure infiltrometer. the measurement of ks by these met...

Beta-titanium alloys containing only fully biocompatible elements are very perspective materials for production of bioimplants. They have good properties for use as biomaterials, including above mentioned biochemical compatibility, low elastic modulus (important for biomechanical compatibility), in comparisson with previously used alloys. Moreover they are suitable for forging. Perspective meth...
