Constructal design is used to study heat removal from a square heated body with a tree shaped high thermal conductivity pathways embedded in the body. The objective is to minimize the defined maximum dimensionless temperature difference for the body. The thermal conductivity of the body is low, and there is a uniform heat generation on it. The volume of the body is fixed. The amount of high con...

We study dynamical correlation functions in the random-field Heisenberg chain, which probes relaxation times at different length scales. Firstly, we show that time associated with imbalance (examining smallest scale) decreases disorder much faster than one determined by dc conductivity (probing global response of system). argue observed dependence on scale originates from local nonresonant regi...

this investigation aimed to assess genetics of body conformation and feed efficiency traits in a control line of rhode island red (rir) chicken taking single hatched out pedigreed 100 chicks at central avian research institute, izatnagar, india. data was analyzed by least squares analysis of variance. least squares means of chick weight (cw), body weight (bw), shank length (sl), keel length (kl...

The impact of a rigid body and rod finite length made viscoplastic incompressible material moving towards each other at constant velocity is studied in the article. One-dimensional motion considered, i.e., velocity, stress, parameters are considered to be averaged over section. According model viscous-plastic material, divided into two parts: region plastic strain that moves as solid after impa...
