In addition to all the well-known "digestive" activity of the digestive apparatus, which until now was considered its only function, there is still another - "periodic", flowing inside digestion and, apparently, not having a direct relation to it. It happens all the time when the digestion is nt. With the end of it, it arises, and with the beginning, it stops.

In a series of three articles, spline approximation is presented from a geodetic point of view. In part 1, an introduction to spline approximation of 2D curves was given and the basic methodology of spline approximation was demonstrated using splines constructed from ordinary polynomials. In this article (part 2), the notion of B-spline is explained by means of the transition from a representation of a polynomial in the monomial basis (ordinary polynomial) to the Lagrangian form, and from it to the Bernstein form, which finally yields the B-spline representation. Moreover, the direct relation between the B-spline parameters and the parameters of a polynomial in the monomial basis is derived. The numerical stability of the spline approximation approaches discussed in part 1 and in this paper, as well as the potential of splines in deformation detection, will be investigated on numerical examples in the forthcoming part 3.

The well-known epistolary conflict between Fyodor Dostoevsky and Nikolai Strakhov over the latter's slander of the great Russian writer's terrible sins is considered in the article from the point of view a philosophical anthropology and relations not two but between three participants of this story: Dostoyevsky, Strakhov and Tolstoy. This conflict is presented through anthropological, existential, and class prisms of description, based on a reconstruction of Strakhov's concept of man as a controversial, dual, and undefined being reflected in Dostoevsky's work. A direct relation between the definition of the dual nature of man in the works of Strakhov and Dostoevsky and interpersonal conflicts within "boundary forms of literature" is substantiated. Special attention is paid to the class of seminarians, the object of Dostoevsky's targeted criticism. He saw their worst characteristics in Strakhov personality. Tolstoy plays the role of an arbiter in this controversy, assessing the situation both in terms of literary, existential and religious thought. In the course of his examination of this conflict, his unexpected closeness to Dostoevsky was discovered in regard to assessment of Strakhov. The point of their coincidence was the "pink Christianity" of the writers, who justify man in a quite similar manner, in terms of their religious consciousness.

The incidence of head injuries is growing with greater mechanization in industry and an increase in high velocity transport. The injuries could be caused by a penetrating or blunt force either by direct violence or indirectly, such as a fall on the feet or buttocks. There is no direct relation to the severity of injury to skull bones and extent of cerebral disorder.We is reporting two cases of head injury from forensic point of view. TAJ 2010; 23(1): 98-102

Despite this being the age when information is readily available, the analysis,the dissemination, and the effect of pioneering Islamic knowledge inall fields is a relatively recent endeavor with only a handful of books thatcover these areas from an academic point of view. The Muslim Contributionto the Renaissance is a comprehensive addition; it is a collection ofnumerous examples of Islamic innovation, and places these examples in their historical context in direct relation to the developing West—a timecalled the “Dark Ages”’ in Europe and the “Golden Age” in the Muslimworld. This Golden Age was one of high calibre scholasticism and practicalexploration in all fields, and it directly influenced the emergence in theWest of what was to be called the “Renaissance.” ...

Customer Relationship Management can have great help to different companies of different sizes as it offers direct relation with the efficient in organizing, disseminating, and establishing values. The current study is the investigation into and comparison of Customer Relationship Management (CRM) and Electronic Customer Relationship Management (E-CRM). The study also aims to compare CRM and ECRM. The study also aims at showing to what extent building good relationships with the customer is of great role to companies. The study reviewed the recent articles published in the international databases. No exclusion criteria were made according to the country or location of the study. It views profit from another perspective as it focuses on establishing good relationships with the customers and clients as it is a better window to create customer retention and loyalty and thus lead to profits is seen and treated from the customers and client's retention and loyalty point of view to assure customers and clients loyalty and retention, the study follows customer orientation approach.

The term geo-sciences has been used here to include the disciplines geology, geophysics and geochemistry. However, in order to apply geophysics and geochemistry effectively one must begin with a geological model. Therefore, the science of geology should be used as the basis for lunar exploration. From an astronomical point of view, a lunar terrain heavily impacted with meteors appears the more reasonable; although from a geological standpoint, volcanism seems the more probable mechanism. A surface liberally marked with volcanic features has been advocated by such geologists as Bülow, Dana, Suess, von Wolff, Shaler, Spurr, and Kuno. In this paper, both the impact and volcanic hypotheses are considered in the application of the geo-sciences to manned lunar exploration. However, more emphasis is placed on the volcanic, or more correctly the defluidization, hypothesis to account for lunar surface features.

ABSTRACTThe mechanism by which a shepherd satellite exerts a confining torque on a ring is considered from the point of view of a single ring particle. It is still not clear how one might most meaningfully include damping effects and other collisional processes into this type of approach to the problem.

The origin of mica polytypes has long been a challenging problem for crystal- lographers, mineralogists and petrologists. From the petrological point of view, interest in this field arose from the potential use of layer stacking data to furnish further informations about equilibrium and/or kinetic conditions prevailing during the crystallization of the widespread mica-bearing rocks. From the compilation of previous experimental works dealing with the occurrence domains of the various mica "polymorphs" (1Mr, 1M, 2M1, 2M2 and 3T) within water-pressure vs temperature fields, it became clear that most of these modifications should be considered as metastable for a fixed mica species. Furthermore, the natural occurrence of long-period (or complex) polytypes could not be accounted for by phase considerations. This highlighted the need of a more detailed kinetic approach of the problem and, in particular, of the role growth mechanisms of basal faces could play in this crystallographic phenomenon.

1. Introduction. Studies of radiation damage in ceramics are of interest not only from a fundamental point of view but also because it is important to understand the behavior of ceramics in various practical radiation enyironments- fission and fusion reactors, nuclear waste storage media, ion-implantation devices, outer space, etc. A great deal of work has been done on the spectroscopy of point defects and small defect clusters in ceramics, but relatively little has been performed on defect agglomeration using transmission electron microscopy (TEM) in the same kind of detail that has been so successful in metals. This article will assess our present understanding of radiation damage in ceramics with illustrations using results obtained from the authors' work.
