The performance metric for tank cars and other hazardous materials vehicles involved in accidents has generally been conditional probability of release given involvement in an accident. This metric considers the probability of a release event occurring but does not take into account the quantity of product lost in a release incident. In this paper, a new metric termed “release risk” is introduc...

in addition to increment of the vehicle sprung mass, the main physical effects of addition of cng tank to the vehicle are the longitudinal and height displacement of center of gravity, which have the most influences on the handling, braking, roll stability and spin stability of the vehicle. increment of cng tank mass to the sprung mass of the vehicle increases the vehicle under-steer gradient, ...

knowledge of fluid flow can play a basic role in optimizing mixing processes. in preparation of sodium perborate, sodium metaborate and hydrogen peroxide, as raw materials, mix and react in the presence of a turbine mixer. in this investigation, the effect of the presence of baffle in a mixing tank equipped with a two-impeller turbine agitator was studied. at first, steady state flow in the tan...

The differentiation of bone-resorbing osteoclasts is induced by RANKL signaling, and leads to the activation of NF-κB via TRAF6 activation. TRAF family member-associated NF-κB activator (TANK) acts as a negative regulator of Toll-like receptors (TLRs) and B-cell receptor (BCR) signaling by inhibiting TRAF6 activation. Tank(-/-) mice spontaneously develop autoimmune glomerular nephritis in an IL...

In order to study the dynamic response of LNG storage tank under action seismic load and isolation effect lead-core rubber bearing, this paper establishes experimental model with reference structural form large-scale tank, test is obtained using a shaking table test. Simplified mechanical models non-isolated isolated tanks are proposed responses corresponding calculated Newmark-beta method. Und...

Planar straining and destraining of turbulence is an idealized form of turbulencemeanflow interaction that is representative of many complex engineering applications. This paper studies experimentally the response of turbulence subjected to a process involving planar straining, a brief relaxation and destraining. Subsequent analysis quantifies the impact of the applied distortions on model coef...

the present work examines leaching of lipoxygenase-1 from soybean flour employing stirred tank vessel. the effect of operating parameters, impellers speed, operational period, temperature, ph and scale-up were considered.the acetic acid ph: 5.2 increased the leaching of lipoxygenase- 1.the sensitivity of agitator speed and geometrical-scale-up on the enzymeleaching has been conducted. the effec...

There has been renewed interest in the performance, functionality, and sustainability of traditional small-scale storage interventions (check dams, farm bunds tanks) used within semi-arid regions for improvement local water security landscape preservation. The Central Groundwater Board India is encouraging construction such alleviation scarcity to improve groundwater recharge. It important reso...

The simulated moving bed (SMB) is a well-established, fully continuous process for chromatographic separation of difficult tasks with overlapping peaks, but it relatively complex. 1-SMB, which uses only one column includes residence time zones to preserve concentration profiles, simpler semi-continuous alternative. This work examines the possible design these zones. Simulation studies were cond...

This paper represents a detailed techno-economic analysis of typical commercial-scale catalytic decarboxylation process naphthenic acids over HZSM-5 zeolite. Simulation the has been performed in ASPEN Plus®. The performance modeled unit was compared to experimental results data from similar plant. Two models were developed for proposed industrial plant based on continuous flow reactors; first i...
