The HAP complex occurs in many eukaryotic organisms and is involved in multiple physiological processes. Here it was found that in Picea wilsonii, HAP5 (PwHAP5), a putative CCAAT-binding transcription factor gene, is involved in pollen tube development and control of tube orientation. Quantitative real-time reverse transcription-PCR showed that PwHAP5 transcripts were expressed strongly in germ...

In order to study the influence of change guide vane airfoil on flow characteristics in draft tube a reversible hydraulic turbine, turbine was used as object study, and effect pattern, energy loss, pressure pulsation area studied based SST k-ω turbulence model. The results show that under low conditions, modified movable directly affects direction speed water entering tube, reduces density vort...

In this thesis a theoretical expression for the conductance through a bent nanotube is derived. The idea is inspired by a recent work by K. Flensberg and C. Markus, in which bent nanotubes are shown to be a prominent candidate for qubit realization [1]. An approximate Hamiltonian for graphene in the vicinity of the high-symmetry K(K′)-points is developed from the tightbinding model. An extensio...

A fast, easy anastomotic technique with a high patency rate would facilitate the development of microvascular surgery. This article describes a new nonsuture method of end-to-side microvascular anastomosis using a soluble polyvinyl alcohol (PVA) T-shaped tube as an internal stent and plastic adhesive. Two kinds of T-shaped tubes were used: Type I tube had a short straight tube connected to a lo...

CORRECTED transposition is commonly considered to be the resuilt of a leftward l)ending of the bulboventricular loop instead of a rightward bending, with concomitantly abnormal development of the trtuncuis septum.'-3 Recently an embryologic study was carried out by one of u-s of normal eight to 19 somites hulman embryos (Streeter's age groups horizon X and XI) and a 6.6-mm. human embryo with an...

The influences of diameter and length of the Fe-N₄-patched carbon nanotubes (Fe-N₄/CNTs) on oxygen reduction reaction (ORR) activity were investigated by density functional theory method using the BLYP/DZP basis set. The results indicate that the stability of the Fe-N₄ catalytic site in Fe-N₄/CNTs will be enhanced with a larger tube diameter, but reduced with shorter tube length. A tube with to...

Recently friction stir welding for manufacturing of welded tubes has been developed. Friction stir welding is a continuous solid state welding process in which a non-consumable rotating tool using severe plastic deformation Can join materials can be join materials. Commonly, a portion of a specially shaped rotating tool is plunged between metalsjoint cross section and adjacent faces of the join...

BACKGROUND The EndoFlex is a new type of tracheal tube with an adjustable distal tip that can be bent without the use of a stylet. The aim of this study was to compare a standard endotracheal tube with the EndoFlex tracheal tube for intubation in patients with simulated cervical spine injury. METHODS A group of 60 patients without any kind of the cervical spine injury, classified as the ASA p...

The paper is focused on an analysis and optimization of the rotary draw benging process to eliminate bent tube ovality by modification pressure bar geometry. bending realized WafiosCNC machine. A that for automotive application made 34MnB5 steel. Currently, after angle 120°, unacceptable occurs. Therefore, it necessary improve quality production thus prevent formation ovality. In this case, ge...
