Prior to the 2001 CMER pilot study, several TFW cooperators conducted independent field studies of the distribution of perennial and seasonal headwater streams (Table 1). All of the studies were conducted during the summer low flow seasons of 1998 or 2000, in part, to evaluate proposed regulatory guidelines that differentiate non-fish-bearing headwater streams on the basis of the seasonal flow ...

in recent years several studies have been done in the field of laminar flame speed. one of the important characteristics of the combustion is the laminar flame speed. in this study, the effects of co2 and n2 on the laminar flame speed of natural gas and gasoline fuel mixture have been investigated. schlieren method has been used in this study. experiments were carried out at pressure of 1 bar a...

Background: Laminar flow ventilation systems were developed to reduce surgical contamination in joint arthroplastyto avoid periprosthetic joint infection (PJI). The goals of this study are to evaluate the cost-effectiveness and economicviability of installing and maintaining a laminar flow system in an operating room.Methods: A Monte Carlo simulation was used to evaluate the c...

To reveal the inner mechanism of gas explosion dynamic behavior affected by gas equivalent concentration, a high speed Schlieren image system and flow field measurement technology was applied to record the gas explosion flame propagation and flame structure transition. The results show that a flame front structure transition occurs, followed by a flame accelerating propagation process. The lami...

We consider the inverse mean curvature flow in RobertsonWalker spacetimes that satisfy the Einstein equations and have a big crunch singularity and prove that under natural conditions the rescaled inverse mean curvature flow provides a smooth transition from big crunch to big bang. We also construct an example showing that in general the transition flow is only of class C.

Occurrence of laminar separation bubbles on solid walls of an elliptic cylinder has been simulated using a recently developed transitional model for boundary layer flows. Computational method is based on the solution of the Reynolds averaged Navier-Stokes (RANS) equations and the eddy-viscosity concept. Transitional model tries to simulate streamwise fluctuations, induced by freestream turbulen...

An autoradiographic method (14C-iodoantipyrine autoradiography) was used to measure regional optic nerve blood flow (ONBF) under basal conditions in 11 adult female cats. Flow was measured in six regions of the optic nerve: (1) prelaminar, (2) laminar, (3) 1 mm post-laminar, (4) 4 mm post-laminar, (5) 6 mm post-laminar, and (6) intracranial optic nerve and chiasm. A gradient of flow rates was f...

A laminar family is a collection A of subsets of a set E such that, for any two intersecting sets, one is contained in the other. For a capacity function c on A, let I be {I : |I ∩ A| ≤ c(A) for all A ∈ A}. Then I is the collection of independent sets of a (laminar) matroid on E. We present a method of compacting laminar presentations, characterize the class of laminar matroids by their exclude...
