This chapter provides four case histories that can be used in the training of future users of the International Schedule for the Integrated Assessment and Staging of Care for Dementia (IDEAL schedule) and its accompanying ‘Menu of care options’. The case histories describe patients with different types and severity levels of dementia and have been written in a manner that makes them understandable in different settings or countries, as well as having been shown to be useful in the training of users of the schedule in different countries. Ratings for the case histories are provided according to the seven dimensions of the IDEAL schedule, with the consequent links to the ‘Menu of care options’. The chapter also includes suggestions about the development of local case histories typical for the setting in which the schedule will be used when training users in that setting.

The objective of perforating is to maximize well productivity by establishing good connectivity between the wellbore and formation. The conventional method of perforation — perforation by shooting (PS) — cannot achieve expected wellbore productivity due to a region of reduced permeability around the perforation tunnel. In this study, it has been established that permeability is decreased in the range of 30%–75% due to the implementation of the PS technique compared to the openhole completion. As a result, a new perforation technique — perforation by drilling (PD) — has been proposed in this paper. To simulate a perforated completion, cylindrical sand samples (0.0572 in OD) consolidated with cement with varying porosity were prepared. These samples were perforated (0.0136 m ED) by the PS, PD and Casting techniques. Perforations created by the Casting techniques are considered the ideal, openhole perforation tunnel. Fluid flow rates and differential pressure across the perforated samples were measured for three different types of samples using “Geotechnical Digital System” triaxial testing set-up. Fluid flow rates with changing differential pressure and finally pressure build-up data with time indicates the PD technique can achieve better wellbore productivity compared to the PS technique. Results indicate that at 100 kPa differential pressure the PS, PD and Casting techniques can achieve 0.20 mL/s, 0.65 mL/s and 1.00 mL/s fluid flow rates respectively across a sample.

Existing research on work hour mismatches has examined gender and occupational differences, but it has largely assumed that these factors work independently of each other. This paper combines insights from the stress of higher status hypothesis and the concept of the ideal worker to examine the intersections of gender and occupation in relation to inequalities in workers’ abilities to control the amount of time they spend in paid work. I also offer a longitudinal and process-oriented analysis by examining how men and women in upper, middle, and lower prestige occupations differ in their chances of having hour mismatches, resolving mismatches, and in the methods through which they resolve them. Findings indicate that men and women experience different types of mismatches and men in upper level occupations are at greater risk of mismatches and least likely to find resolutions, yet outcomes are heavily influenced by the intersections of gender and occupation, illustrating the need for this type of analysis. There are few results to indicate differences in the mechanism of mismatch resolution by either gender or occupation.

Because of different types of load, material properties deviation and construction errors, structures have initial defects inevitably. Therefore structural damages emerge easily and have strong randomness. At the same time, the ideal design model often has difference with structure in service. To most structures, the initial testing dates cannot be obtained, while this initial model is very important to structural damage detection. So the ideal model needs to revise. In this paper, elastic modulus, Poisson ratio and link section area are given as initial random defects and these defects obey normal distribution which can be constructed by Monte Carlo probabilistic design method. Firstly, the sensitivity parameters to structural response will be received by PDS technology from Ansys. Next, the square pyramid space grid models with random defects were obtained. Finally, given link element damage, using the method combined curvature mode difference with wavelet transform, the link element damage can be determined. Through analysis, the effects about the initial defects to damage detection will be obtained.

AbstractDifferent models of tumor growth are considered. Some mathematical methods are developed to analyze the dynamics of mutations enabling cells in cancer patients to metas-tize. The mathematical models consist of some stochastic dynamical systems describing tumor cells and immune effectors. It is also considered a method to find the ideal outcome of some treatments. Some different types of dendritic cells are considered. The obtained results will help to find some suitable treatments,which can be successful in returning an aggressive tumor to its passive,non-immune evading state. The principle goal of this paper is to find ways to treat the cancer tumors before they can reach an advanced stage devel-opmen.AMS Subject Classifications92B05, 37C45.

AbstractAll-ceramic systems represent an excellent restorative alternative for fixed dental prostheses, single crowns, and veneers in the anterior dentition. With respect to improved mechanical properties, lithium disilicate ceramic material provide a broad range of indications, and extended veneers can serve as an alternative to full crowns. Although ceramic veneers represent a more conservative approach compared to crowns, the correct indication is essential to achieving the ideal outcome. The following case reports describe two types of fixed restorations of the anterior dentition: extended lithium disilicate ceramic veneers and lithium disilicate full crowns. Factors influencing treatment selection for each type of restorations are presented.

This article discusses the basic concepts of Berdyaev’s philosophy, traces the relationship of his philosophical view and political convictions. This relationship is revealed through the concept of personality, which is the central concept of Berdyaev’s philosophy. Through the attitude to the personality, we can reveal the attitude of N. A. Berdyaev to the institution of the state, understand the social preferences of the Russian philosopher, who has come a long way from the representative of Russian Marxism to Russian religious philosophy. Having understood his ideas about the ideal structure of society, we can understand the attitude of N. A. Berdyaev to the Soviet state. The article distinguishes between two different types of relationships: the individual and society - collectivism and communitarianism. Berdyaev’s view is shown in the origins of Russian communism, which, in the opinion of the philosopher, are found not only in Western European philosophy, but also in the historical mentality of Russian people.

Athletes from contact sports are more prone to orofacial injuries because of the exposure to possible shocks and collisions derived from physical proximity. The use of protector polymeric mouthguards proved to be useful in the prevention of the described injuries. There are different types of mouthguards with varying ranges of protection and prices, but they are all made from polymers and share the same propose: to absorb and dissipate the impact energy resulting from the shocks. As they are used inside the mouth, they should not impair breathing and speaking nor compromise the comfort of the athlete. However, the ideal mouthguard is yet to be created. The choice of the most appropriate polymeric material and the standard required properties have not yet been reported. Regardless of the numerous studies in this field, normalized control parameters for both material characterization and mouthguard fabrication are absent. This paper aims to present a review of the current types of available mouthguards and their properties/characteristics. Moreover, a detailed description of the most common polymers for the fabrication of mouthguards, together with the manufacturing techniques, are discussed.

A 2D bond-breaking model is presented that allows the extraction of the intrinsic line or edge energy, fracture toughness, and strain energy release rate of graphene from measured and calculated 2D Young’s moduli and 2D pristine strengths. The ideal fracture stress of perfect graphene is compared with the critical fracture stresses of defective graphene sheets containing different types of imperfections. This includes (multiple) vacancies in the subnanometer range, grain boundaries, slits in the nanometer region, and artificial pre-cracks with sizes of 30 nm to 1 ?m. Independent of the type of defect, a common dependence of the critical fracture strength on the square root of half defect size is observed. Furthermore, the results suggest the applicability of the Griffith relation at length scales of several nanometers. This observation is not consistent with simulations pointing to the existence of a flaw tolerance for defects with nanometer size. According to simulations for quasi-static growth of pre-existing cracks, the atomic mechanism may also consist of an alternating sequence of bond-breaking and bond-rotation steps with a straight extension of the crack path. Independent of the exact atomic failure mechanism brittle fracture of graphene is generally assumed at low temperatures.
