Darcy's Law is one of the most essential concepts in hydrogeology. Before moving on to more complex problems, students must first thoroughly understand the basic principles of one-dimensional fluid flow through saturated porous media that are embodied in Darcy’s Law. We believe that the best way for students to learn these principles is through experimentation. In this paper, we introduce an ex...

IN THE experiments performed on the canine heart-lung preparation, Patterson, Piper, and Starling observed that when venous return was augmented, cardiac performance initially increased, but when venous return was elevated beyond a critical level, the performance progressively declined, i.e., there was a descending limb of the Starling curve.1-3 During the past 20 years a number of studies have...

this research considers whenever husband's permission is necessary in islam jurisprudence. there are many traditionsabout this subject. these traditionsexpress that woman is obliged to get permission from her husband to do some religious act recommended such as fasting, pilgrimage,aitkafand other daily affairs such as leaving home, vow and so on.therefore,it is necessary to examine the imp...

In Image processing face recognition plays an important role in various biometric applications. WLD (Weber’s Local Descriptor) will be used for face recognition. WLD is a texture descriptor that performs better than other similar descriptors but it is holistic due to its very construction. Image is divided into number of blocks and WLD is calculated for each block and then concatenate them. Thi...

The theory of open quantum systems is used to study the local temperature and heat currents in metallic nanowires connected to leads at different temperatures. We show that for ballistic wires the local temperature is almost uniform along the wire and Fourier’s law is invalid. By gradually increasing disorder, a uniform temperature gradient ensues inside the wire and the thermal current linearl...

In the paper we explain the notion of geometrical net from the view of coding of music information. A direct, elementary, and very short alternative proof of the assertion that there are no transcendental semitones generating Pythagorean system, is given. This is a conclusion of the negation of the psychological Weber – Fechner’s law. Further, we discuss about a kind of uncertainty bounded with...

the paper discusses study of kant's deontological ethics in organization and comparison of it with pillars of worldly ethic in organization and whether kant's ethics is compatible with them. kant's ethics is one of the most deontological theories in which intention and motive of action are basic roles. kant merely regarded the motive of action of moral rules, respect to them. kan...

Let (Et, t ≥ 0) be a geometric Brownian motion. In this paper, we compute the law of a generalization of Dufresne’s translated perpetuity (following the terminology of Salminen-Yor) : ∫ +∞ 0 E s (E2 s + 2aEs + b)2 ds, and show that, in some cases, this perpetuity is identical in law with the first hitting time of a threedimensional Bessel process with drift. We also study the law of the followi...

Strike activity in Spain is unusually high compared to most other developed countries and, moreover, it has remained at a high level for the last decade, whilst strike rates have been falling in most other countries. One possible explanation for this poor strikes record is Spanish labour law with respect to industrial disputes which may be too permissive, or have remained permissive whilst othe...
