the goal of this study was to define the normal range of diameter in the deep vein of the lower limb and to compare this range with diameter of the veins with acute thrombosis and of veins with chronic thrombosis by using color doppler sonography. the study was cross sectional. the vein diameter and vein to artery ratio in different levels were measured and the following results were obtained. ...

We give asymptotically sharp upper bounds for the maximum diameter and radius of (i) a connected graph, {ii) a connected trangle-free graph, (iii) a connected C,-free graph with n vertices and with minimum degree 6, where n tends to infinity. Some conjectures for J&-free graphs are also stated. Let G be a connected graph with vertex set V(G) and edge set E(G). For any XJJ E V(G) let dG(x,y) den...

Drought is one of the most critical environmental stresses that reduce agricultural production. This study aimed to examine effects individual and simultaneous inoculation Rhizophagus intraradices, Serendipita indica, Pseudomonas fluorescens on physical properties soil growth parameters single cross 704 maize under three levels drought stress (80%, 50%, 25% available water). It was found intrar...

Background: The seeds of some medicinal plants and their compounds have long been valued for their numerous health benefits. Objective:To investigate some physical and chemical properties of Salvia spp. Methods: Some physico-chemical properties in five species of Salvia seeds (consisted of S. officinalis L., S. macrosiphon L., S. hypoleuca L., S. sclarea L. and S. nemorosa L.) were measured ...

Variation in angiosperm vessel diameter is of major functional significance. In the light of recent models predicting optimal vessel taper given resistance imposed by conductive path length, we tested the prediction that plant size should predict vessel diameter, with dryland plants having narrower vessels for their stem sizes. We assembled a comparative dataset including vessel and stem diamet...

Nanofluidic transistors (NFTs), composed of solid-state nanopores with an electrically controlled embedded gate electrode, promise exciting new ways to build chemical and biological circuits that can be used in drug-delivery and lab-on-a-chip systems. However, the reliable fabrication of sub-10nm gated nanopores and control over biomolecule capture and transport has been challenging. Herein, we...

To point 2: The deduction of number distributions/mass mixing ratios from single particle data is linked with rather large uncertainties. Nevertheless, we have added the results of our calculation and the discussion of these values (see end of comment). The mass mixing ratio will be around 0.1 ppbm for all nonvolatile particles and the dN/dlogDP for a particle diameter of 0.75 μm is around 10ˆ-...
