An optimal management of large Karst sites, with emphasis on the conservation of cave fauna while allowing recreational use, is proposed. A detailed study of the relative biological value of each section in a reference cave, the east Belgian ‘Grottes de Han’ Cave, was made in comparison with 40 others in Belgium.Computer analysis provided a selection of optimal routes through the Cave. Each different route reflects the synthetic coefficients derived to weight biological and aesthetic values. This method of optimal cave resource control, developed to prevent deterioration in underground environments, can also be applied to other natural sites visited by humans.

Computer modeling of the wrist has followed other fields in the search for descriptive methods to understand the biomechanics of injury. Using patient-specific 3D computer models, we may better understand the biomechanics of wrist fractures in order to plan better care. We may better estimate fracture morphology and stability and evaluate surgical indications, design more adequate or effective surgical approaches and develop novel methods of therapy. The purpose of this review is to question the actual advances made in the understanding of wrist fractures using computer models.

Evidence-based assessment relies on research and theory to inform the selection of constructs to be assessed for a specific assessment purpose, the methods and measures to be used in the assessment, and the manner in which the assessment process unfolds. An evidence-based approach to clinical assessment necessitates the recognition that, even when evidence-based instruments are used, the assessment process is a decision-making task in which hypotheses must be iteratively formulated and tested. In this chapter, we review (a) the progress that has been made in developing an evidence-based approach to clinical assessment in the past decade and (b) the many challenges that lie ahead if clinical assessment is to be truly evidence-based.

AbstractAn altered facial appearance is more difficult to face, than problems related to ill-fitting denture or eating. The selection of maxillary anterior teeth for complete denture has long posed problem in clinical practice and a controversy about the best method to employ still exists. An attempt is made in the present study to clinically correlate the face form with maxillary central incisor tooth form in males and females of Davangere population. In 1914, Leon William's projected the “the form method” where he classified facial forms as square, tapering, and ovoid. Maxillary central incisors were selected according to the facial forms.Of total 100 subjects four different tooth forms and face forms were evaluated. They are: square, ovoid, square-tapered, tapered. No significant correlation existed between face form in male and females. Females exhibited greater correlation between face forms and inverted tooth form but that correlation is not sufficient to serve as a guide for selection of anterior teeth.

High Efficiency Deep Grinding (HEDG) has been known to secure high removal rates in grinding processes at high wheel speed, relatively large depth of cut and moderately high work speed. High removal rates in HEDG are associated with very efficient grinding and secure very low specific energy comparable to conventional cutting processes. Though there exist HEDG-enabled machine tools, the wide spread of HEDG has been very limited due to the requirement for the machine tool and process design to ensure workpiece surface integrity. HEDG is an aggressive machining process that requires an adequate selection of grinding parameters in order to be successful within a given machine tool and workpiece configuration. This paper presents progress made in the development of a specialised HEDG machine. Results of HEDG processes obtained from the designed machine tool are presented to illustrate achievable high specific removal rates. Specific grinding energies are shown alongside with measured contact arc temperatures. An enhanced single-pole thermocouple technique was used to measure the actual contact temperatures in deep cutting. The performance of conventional wheels is depicted together with the performance of a CBN wheel obtained from actual industrial tests.

Due to the fact that the major portion of pharmaceuticals and agrochemicals contains heterocyclic units and since the overall number of commercially used heterocyclic compounds is steadily growing, heterocyclic chemistry remains in the focus of the synthetic community. Enormous efforts have been made in the last decades in order to render the production of such compounds more selective and efficient. However, most of the conventional methods for the construction of heterocyclic cores still involve the use of strong acids or bases, the operation at elevated temperatures and/or the use of expensive catalysts and reagents. In this regard, electrosynthesis can provide a milder and more environmentally benign alternative. In fact, numerous examples for the electrochemical construction of heterocycles have been reported in recent years. These cases demonstrate that ring formation can be achieved efficiently under ambient conditions without the use of additional reagents. In order to account for the recent developments in this field, a selection of representative reactions is presented and discussed in this review.

Editor's Note: Guidelines for Selecting Books to Review Occasionally, we receive questions regarding the selection of books reviewed in the Journal of Economic Literature. A statement of our guidelines for book selection might be useful, therefore. The general purpose of our book reviews is to help keep members of the American Economic Association informed of significant English-language publications in economics research. Annotations are published of all books received. However, we receive many more books than we are able to review so choices must be made in selecting books for review. We try to identify for review scholarly, well-researched books that embody serious and original research on a particular topic. We do not review textbooks. Other things equal, we avoid volumes of collected papers such as festschriften and conference volumes. Often such volumes pose difficult problems for the reviewer who may find himself having to describe and evaluate many different contributions. Among such volumes, we prefer those on a single, well-defined theme that a typical reviewer may develop in his review. A volume that collects together papers from a wide assortment of different topics is not preferred to one devoted exclusively to one topic. We avoid volumes that collect previously published papers unless there is some material value added from bringing the papers together. Also, we refrain from reviewing second or revised editions unless the revisions of the original edition are really substantial. Our policy is not to accept offers to review (and unsolicited reviews of) particular books. We have examined the consequences of an alternative policy and have determined that we lack the resources to deal appropriately with unsolicited reviews. Coauthorship of reviews is not forbidden but discouraged and we ask our invited reviewers to discuss with us first any changes in the authorship or assigned length of a review.

The fast growth of the service sector is one of the characteristic features of the contemporary economy. Amongst other CEE countries, Poland is one of the emerging locations for this sector. The aim of the paper is to examine and compare the business service sector in India, Ireland and Poland. Both India and Ireland are exceptional locations for this industry, so comparing the state and operating conditions in Poland with those countries can be insightful. A literature study is used to determine the motives of companies undertaking offshore investments, upon which a selection of location factors is made. In the empirical part, those factors are analyzed in a descriptive way. This allows us to draw conclusions concerning this sector in Poland. This country, to some extent, possesses selected positive features of both India and Ireland, which explains the current growth of the sector.

The attempt to expand the traditional academic ideas about diagnostics in social work has been made, in particular the selection of social diagnostic methods, the purposes of their application, professional situations and focus groups in which these methods can be applied.The research determines the opportunities of application social diagnostics in pedagogical practice, to identify the optimal methods of social diagnostics and the conditions in which it is advisable to apply this type of diagnostic by professional participants of the educational process.Other methods have been proposed in addition to the classic list of social diagnostic methods, such as interlocution, interviews and surveys of all types; they are unpopular in modern social and socio-pedagogical work, but due to their accessibility, validity, ease of processing and in formativeness can be used even by recent graduates. These include a genogram, a family sociogram, as well as an eco-map, the map of social environment and the map of social contacts.The viability of applying social diagnostic methods in a teacher’s daily practice for preventing, revealing and solving social problems has been determined.During the investigation, the author concludes that social diagnostic is the most significant technique among many universal ones that a social worker/social pedagogue can use in his/her work. The optimal location for diagnostic work is an educational institution. It provides quick access to the client base with the widest range, allows you to work with clients in the system of social relations, enables diagnostic work with less motivational pressure, covers relationships with parents/families and facilitates their involvement in preventive work

Film genre patterns and complex narrative strategies in the service of authorshipFrom the Euro-American canon of contemporary filmmaking a selection of films has been made, the directors of which transition from low-budget, arthouse, regional first features made in the years 1997–1998 mainly Cube and Pi, with occasional references to Run, Lola, Run and Following to big-budget, Hollywood-funded blockbusters presented in the years 2009–2010 Splice and Black Swan, occasionally referring to The International and Inception. Within this framework the issue of how generic patterns are used by these directors fond of narrative complexity is discussed. While in the debut features narrative complexity is the main issue, leading to a revisionist usage of sci-fi Natali and psychological thriller/horror Aronofsky, as well as action film Tykwer and noir detection film Nolan, in the 2009–2010 blockbusters narrative complexity is hidden behind apparently sincere generic imitation. This latter procedure, on closer inspection, reveals the allegorical recreation of genres as types as defined by Laetz and McIver Lopes in The Routledge Companion to Film and Philosophy. The aim is to examine narratively complex designs as tools in establishing the authorial names of these directors, based on their first features, with attention paid to the consistency of film genres referenced.
