Zooplankton populations are spatially heterogeneous in nature and inside ship ballast tanks. Sampling methods should take heterogeneity into account, particularly when estimating quantitative variables such as abundance or concentration. It is particularly important to generate unbiased estimates of zooplankton concentration in ballast water when assessing compliance with new international ball...

With the rapid development of intelligent buildings, a lot of researchers have found that it is difficult to establish mathematical model when the problem that energy-saving in water supply system of an intelligent building tank is focused, because that the outflow of the tank volume is volatile when the water is daily living water. In this paper, fuzzy control theory is used to establish a flu...

The paper outlines a method to determine the sedimentation efficiency in modernized tanks with incorporated lamella packets. The method takes into account the properties of the suspension (density, viscosity, solid phase distribution) and tank design parameters – flow intensity and settling surface. Several types of grain size distributions are considered: the log-normal distribution and genera...

Electric fish sense the perturbations of a self generated electric field through their electroreceptive skin. This sense allows them to navigate and reconstruct their environment in conditions where vision and sonar cannot work. In this article, we use a sensor inspired by this sense to address both problems of locating and estimating the size of small objects (electrolocation) and navigating i...

PPO-inhibiting herbicides in combination with glyphosate for postemergence applications is a common approach to manage glyphosate- and ALS-inhibitor-resistant weeds. PPO-inhibitors can reduce translocation when applied tank-mixtures, but adjuvants may be used overcome this effect. Additionally, optimal droplet size affected by tank-mixtures of different it crucial herbicide efficacy. Field gree...

Osteoclasts are the principle bone-resorbing cells. Precise control of balanced osteoclast activity is indispensable for bone homeostasis. Osteoclast activation mediated by RANK-TRAF6 axis has been clearly identified. However, a negative regulation-machinery in osteoclast remains unclear. TRAF family member-associated NF-κB activator (TANK) is induced by about 10 folds during osteoclastogenesis...

The crashworthiness of helicopter fuel tank is vital to the survivability of the passengers and structures. In order to understand and improve the crashworthiness of the soft fuel tank of helicopter during the crash, this paper investigated the dynamic behavior of the nylon woven fabric composite fuel tank striking on the ground. A fluid-structure interaction finite element model of the fuel ta...

Aiming at the characteristics of multi-size particles in waste heat recovery sinter vertical tank, a steady-state gas-solid transfer model tank was established. Based on exergy analysis, influences physical properties and working conditions capacity were studied. Finally, optimum parameter combination obtained by orthogonal test method. Results showed that mono-size no longer suitable for analy...
