As networking has become popular, Web-learning tends to be a trend while designing a tool. Moreover, five-axis machining has been widely used in industry recently; however, it has potential axial table colliding problems. Thus this paper aims at proposing an efficient web-learning collision detection tool on five-axis machining. However, collision detection consumes heavy resource that few devi...

The renin-angiotensin system (RAS) is a major regulator of renal fibrosis. Besides the classical renin/Angiotensin-converting enzyme (ACE)/angiotensin II (Ang II)/AT1 and AT2 axis, multiple new axes have been recently described. The new members have added new dimensions to RAS, including the ACE2/Ang(1-7)/Mas receptor axis, the prorenin/(pro)renin receptor(PRR)/intracelluar pathway axis, and th...

Diabetes is a metabolic disorder which affects whole body systems including reproductive system. Diabetes is also a contributing factor to infertility. Metformin is one of the most common drugs to control hyperglycemia. In this study, 36 adult Sprague-Dawley female rats (170-210 g) were divided into 3 groups (control, diabetic and diabetic-treated by metformin). In second and third groups, diab...

Let Γ ⊂ Rs be a lattice, obtained from a module in a totally real algebraic number field. Let G be an axis parallel parallelepiped, and let |G| be a volume of G. In this paper we prove that lim sup |G|→∞ (det Γ#(Γ ∩G)− |G|)/ ln |G| > 0. Thus the known estimate det Γ#(Γ ∩ G) = |G| + O(ln |G|) is exact. We obtain also a similar result for the low discrepancy sequence corresponding to Γ.

Crystals of glycine phosphite G l y H 3 P 0 3 (abbreviated as GPI ) belong to the low-symmetry representatives of hydrogen-bonded crystals. At room temperature the unit cell of this compound is monoclinic (space group P21 /a) and contains four formula units [1]. The crystal structure is characterised by the presence of infinite chains of hydrogen-bonded phosphite anions that are directed along ...

The Turing reaction-diffusion model explains how identical cells can self-organize to form spatial patterns. It has been suggested that extracellular signaling molecules with different diffusion coefficients underlie this model, but the contribution of cell-autonomous signaling components is largely unknown. We developed an automated mathematical analysis to derive a catalog of realistic Turing...

These days, in industrial robot applications, servo motors with reducer have been used to move manipulators. Due the weight of parts, it causes undesirable conditions such as backward movement, downward movement and vibration caused by moments inertia at time movement. In this study, step motor ball screw driven actuators, which use push-pull force instead reducers, were utilized provide rotati...

introduction: different mechanisms are involved in stress induced analgesia (sia) and hyperalgesia (sih). repeated stress induces development of tolerance to sia. the role of hpa axis and gs signaling pathway in these effects are investigated in the current study. methods: forced swim stress (5 min/day) in water (20±1 ºc) was employed to adult male wistar rats (200-250 g). the nociceptive thres...
