As a paradigm for heat conduction in 1 dimension, we propose a class of models represented by chains of identical cells, each one of which containing an energy storage device called a “tank”. Energy exchange among tanks is mediated by tracer particles, which are injected at characteristic temperatures and rates from heat baths at the two ends of the chain. For stochastic and Hamiltonian models ...

What is a landmine? The purpose of a landmine is to disable, immobilize or kill. It is an explosive device activated either by a person or vehicle, or command detonated by electric wire or radio signal. Most landmines are laid on or just below the surface of the ground and are activated by pressure or trip-wire. Normally manufactured from very durable materials such as plastic, bakelite, concre...

The aim of this study is to examine the effect replacing waste aluminum sawdust (AS) with fine aggregate on strength and durability properties concrete. For this, concrete mixtures a cement dosage 400 kg/m3 water/cement (W/C) ratio 0.40-0.50-0.60 were prepared. AS obtained from Elazig industrial site was added by 0%, 0.5% 1% volume. After curing in pool for 28 days, produced samples subjected a...

Abstract The manufacturing of cement liberates the green-house gasses into atmosphere. To overcome this problem so many alternative materials has been invented by researchers to minimize addition cement. incorporation these as cementitious material in concrete enhances attributes concrete. In scenario metakaolin gained momentum a substitution Most studied performance incorporating normal curing...

Steam accumulation is one of the most effective ways thermal energy storage (TES) for solar (STE) industry. However, steam accumulator concept penalized by a bad relationship between volume and stored; moreover, its discharge process shows decline in pressure, failing to reach nominal conditions turbine. From economic point view, 60% 70% cost TES that pressure vessel tanks (defined as US$/kWhth...

A model scald tank was constructed to study the mixing pattern of water in a poultry scalding system. Tank dimensions were approximately 6 m long by 10.5 cm wide with a water depth of 18 cm. Water was vigorously agitated with compressed air delivered through a 1.9-cm polyvinyl chloride pipe on the bottom of the tank. Food coloring was added to the tank at a single point, and water samples were ...

many researchers have investigated how to increase the overall efficiency of solar-driven thermal systems. several key parameters, such as collector efficiency and storage tank characteristics, may impose some constraints on the annual solar fraction (asf) of such systems. in this paper, the behaviour of integrating the phase change material (pcm) in sdhw systems is modelled and optimized numer...

Elevated water tanks supported by the reinforced concrete (RC) Staging are classified as inverted pendulum structures. These are considered as structures of high post-earthquake importance and should remain functional after the seismic events. National codes of various countries recommend Force-Based Design (FBD) procedure for water tank staging, which does not ensure nonlinear performance leve...

The effect of Vernonia amygdalina Del. leaves on the reproductive potential of male Clarias gariepinus was investigated using 56 fish (425±75.7 g). Four diets with crude protein level of 45% were formulated with different inclusion levels of V. amygdalina leaves. The leaves were added to the basal diet at 0% (control), 5%, 10% and 15% inclusion levels. The 56 male C. gariepinus were randomly di...
