Biomaterials are commonly defined as nonviable materials intended to interface with biological systems to evaluate, treat, augment or replace any tissue, organ or function of the body [].Before a new biomaterial is introduced to the market, various issues are considered, including its designated anatomic location, functional tissue structure and pathobiology, mechanical and ...
2015-8-30 The performance of heat exchangers can be improved to perform a certain heat-transfer duty by heat transfer enhancement techniques. Enhancement techniques can be divided into two categories: passive and active. Active methods require external power, such as electric or acoustic field, mechanical devices, or surface vibration, whereas passive methods do not require external power but make use ...

2020-6-15 The nanofluid also reduced the surface temperature of the CPU and entropy generation rate in the system. A 2.7% decrease in the entropy generation rate of the CPU was attained at 1 Vol% and Re of 300. At 1 Vol% and Re of 700, the CMC/CuO water had an optimal ratio of heat transfer to the pressure drop of 2.29.

2021-11-1 Many studies focus on the buckling behavior and design of pure steel columns exposed to fire. For example, axially and eccentrically loaded columns were studied under fire by Franssen et al. , , .These researchers proposed a procedure for the design of columns under fire loading, which was adopted by EN 1993-1-2 .Gomes et al. proposed alternative formulas to determine the buckling length
2015-11-15 Enzymes are potent catalysts. The enormous catalytic activity of enzymes can perhaps best be expressed by a constant, k cat, that is variously referred to as the turnover rate, turnover frequency or turnover number.This constant represents the number of substrate molecules that can be converted to product by a single enzyme molecule per unit time (usually per minute or per second).

2018-8-1 as follows: (2) R = (T e-T c) / Q where R is thermal resistance (K/W), T e is the average temperature of the evaporator(K), T c is the average temperature at condenser (K), and Q is the amount of heat supplied (W). This ratio is widely used to observe the effectiveness of the PHP. Lesser the value of R, higher is the performance ratings of the PHP.

Liquid asphalt is a petroleum-based product widely used in cities. With urban areas comprised of 45%+ paved surfaces and 20% roofs (), annual demand is 122.5 million metric tons globally and 27 million metric tons in the United States for the liquid asphalt binder that is then typically mixed with other structural materials (e.g., aggregates) depending on usage ().

Steady-state dynamics in a 2D ice-flow model forced by the ocean-atmosphere GCM FOAM, run under relatively warm Snowball conditions (167, 216). Sublimation of meteoric ice (compressed snow) and melting of marine ice (frozen seawater) at low latitudes are balanced by accumulation and freeze-on, respectively, outside the inner tropics.
