Strip Processing systems (SPS’s) are composed of multiple tension zones. These zones are separated by driven rolls such as bridles whose speed is regulated by a closed loop controller. Given that the typical tension regulator regulates tension by trimming the reference to a closed speed loop controller, the designer of the tension regulator cannot ignore the effects of closing the speed loop, a...

Transport of colloids with transient wetting fronts represents an important mechanism of contaminant migration in the vadose zone. The work presented here used steady-state saturated and transient unsaturated flow columns to evaluate the transport of a fluorescent latex microsphere (980 nm in diameter) with capillary wetting fronts of different solution surface tensions and ionic strengths. The...

Structural alterations during epithelial-to-mesenchymal transition (EMT) pose a substantial challenge to the mechanical response of cells and are supposed to be key parameters for an increased malignancy during metastasis. Herein, we report that during EMT, apical tension of the epithelial cell line NMuMG is controlled by cell-cell contacts and the architecture of the underlying actin structure...

A new risk assessment method for anchor dragging is proposed. Using several kinds of information that can be commonly obtained on the navigational bridge ships, touch down point chain to seabed estimated based ship’s equations motion. Firstly, accelerations and velocities ship are numerically evaluated using GPS data. Secondly, hydrodynamic forces, such as added mass, damping force wind force, ...

We identify four orthogonal dimensions along which information in engineering design organizations can be ordered, namely (i) the principle of ordering (top down vs. bottom up), (ii) the structure of ordering (aggregation-decomposition vs. generalization-specialization), (iii) the breadth of ordering (diversity vs. parsimony) and (iv) the perspective of ordering (horizontal vs. historical). Fou...

in order to investigate the effect of soil matric potential and tube layout on yield and water use efficiency of greenhouse cucumber, a field experiment was carried out during 2010 and 2012 growing seasons at an experimental farm in jiroft territory. the treatments were laid out in strip split plot a randomized complete block design with three replications. the treatments were comprised of fore...

child with down's syndrome is an individual who is suitable and eligible to receive early intervention services. this study aimed to measure the family outcome among parents of down syndrome children, on the impact of receiving early intervention and identify the factors influencing it.a cross sectional was conducted from april 2009 until january 2010 with a total of 125 parents of children wit...

Acanthophyllum laxiusculum is one of the most widely distributed species of the genus in Iran that flourishes in steppe and mountainous regions of the country. In the present study, water-soluble content of A. laxiusculum roots was extracted by boiling water and further successively purified partially by a defined solvent system. Surface tension measurements revealed the ability of plant extrac...

Aero-Pipeline Spraying System is a special ultra-working-width precision pesticide sprayer, which can broaden working scope, improve working efficiency, precisely transfer feed liquid to farm field that need to be sprayed, spray pesticides to crops in a very close range, and then improve working precision and reduce the losses of liquid materials such as pesticides. During the ultra-working-wid...
