BACKGROUND The articularis genus muscle pulls the suprapatellar pouch upwards when the knee joint is extended, preventing mechanical impingement of the joint capsule which theoretically could cause anterior knee pain. However, few anatomical studies have addressed this muscle. Here we present the precise morphology of articularis genus. MATERIALS AND METHODS A total of 22 (13 male and 9 femal...

in order to study the effect of different levels of nitrogen and sulfur fertilizers on yield, yield components, content of some elements, qualitative and quantitative traits of spring safflower (serin cv.) an experiment was conducted at agriculture and natural resource research station of ardabil in 2008. this experiment was carried out in factorial experiment in completely randomized block des...

Nutrition as an environmental factor has a special place in the growth, main and sub branches number of Rosa damascena Mill. and these morphological traits affected yield and flower number of the plant. So, this experiment was conducted in the Research Institute of Forest and Rangelands, Karaj, Iran, to evaluate the effect of macro- and micronutrients on the plant growth. A split plot design wa...

The acoustic field in a Pekeris channel with an attenuating basement is critically examined, based on contour integrations of the wave number integrals for the two domains. In both regions, the field consists of a finite sum of proper (square integrable) normal modes plus a branch line integral around a hyperbolic cut. For low bottom attenuation, only "trapped" modes exist but as the loss incre...

The median nerve is usually formed just lateral to the third part of the axillary artery by the union of its medial and lateral roots coming from medial and lateral cords of the brachial plexus respectively. It then descends down in the front of the arm and crosses superficial to the brachial artery from lateral to medial side. It enters the cubital fossa along with the brachial artery. Normall...

The study aimed to evaluate the comparative anatomy of liver and intrahepatic branching portal vein Eurasian otter (Lutra lutra) American mink (Neovison vison). Due their highly valuable fur, minks have expanded range many parts Europe become available for biomedical studies. In this study, ten adult five otters were used. was studied by combined injection dissection technique. macroscopic reve...

An A-tree is a metric space in which any two points are joined by a unique arc. Every arc is isometric to a closed interval of R . When a group G acts on a tree (Z-tree) X without inversion, then X/G is a graph. One gets a presentation of G from the quotient graph X/G with vertex and edge stabilizers attached. For a general R-tree X, there is no such combinatorial structure on X/G . But we can ...
