In this work, the optimum homogeneous phantom size for an equivalent whole-body electromagnetic (EM) modeling is calculated. This will enable the simple characterization of plane wave EM attenuation and far-field link budgets in Active Medical Implant (AMI) applications in the core region of the body for Industrial, Scientific, Medical and MedRadio frequency bands. A computational analysis is done to determine the optimum size in which a minimum phantom size reliably represents a whole-body situation for the corresponding frequency of operation, saving computer and laboratory resources. After the definition of a converge criterion, the computed minimum phantom size for subcutaneous applications, 0–10 mm insertion depth, is 355 × 160 × 255 mm3 for 402 MHz and 868 MHz and a cube with a side of 100 mm and 50 mm for 2.45 GHz and 5.8 GHz, respectively. For deep AMI applications, 10–50 mm insertion depth, the dimensions are 355 × 260 × 255 mm3 for 402 MHz and 868 MHz, and a cube with a side of 200 mm and 150 mm for 2.45 GHz and 5.8 GHz, respectively. A significant reduction in both computational and manufacturing resources for phantom development is thereby achieved. The verification of the model is performed by field measurements in phantoms made by aqueous solutions with sugar.

The widespread formation of unfavorable environmental, the swiftness of modern life with large information and psycho-emotional loads and extremely natural and climatic cataclysms, as well as harmful addictions and wrong way of life of modern human, lead to the development of stress and disruption of the mechanisms of adaptation of the human body and its accelerated wear. This stimulates the development of research on the creation of new methods of integrated assessment of health and quantitative assessment of the aging processes of the body systems and the whole body, as well as the possibilities of new methods of risk assessment of climatic and environmentally related pathological and age-related diseases. The aim of the work was to consider the methodology of quantitative assessment of individual health and the rate of aging of the human body on the basis of the system index of Biological age (BA); description of its essence and structure, requirements for tests - biomarkers of aging used as the index of BA, definition of possibilities and scope of application of the BA method in modern practice of Biomedicine. The use of modern methods of scientific analysis - a systematic approach to the analysis of the processes of human aging and determine its quantitative side - the value of BA, allows a reasonable approach to the choice of the number of BM, to take into account their information content and precision, and the cost of diagnostics and availability for different users, to take into account the specific objectives of the researcher. The use of the index-partial BA allows individual approaching the choice of biomarkers and create personalized panels for the definition of BA programs for the prevention of aging in personalized preventive medicine. The complexity of the content and calculation of indices of BA requires automation and the use of methods of modern computer science and computer calculations and programs. For this purpose, we have created special computer software for diagnosing aging by calculating the BA indices with the possibility of choosing BM and automatic calculation of indicators and conclusions.

Schinckel, A. P., Einstein, M. E., Ajuwon, K. M. and Adeola, O. 2013. Characterization of whole body compositional growth of male ducks during the twenty-nine day post-hatch period. Can. J. Anim. Sci. 93: 113–122. Changes in whole body dry matter, lipid, ash, energy, crude protein, and amino acids were evaluated during a 29 d post-hatch period in White Pekin ducks. Drakes were assigned to slaughter 1, 8, 15, 22, or 29 d post-hatch with four replicates of four ducks per slaughter period. The body weight (BW) data were fitted to the Weibull function with the form:[Formula: see text]where BWit is the BW of the ith duck at t days of age and A, B, C, and IP are parameters. The value of IP, the inflection point, which minimized the residual SD, was 40 d. Values of A (8591 g, SE=190), B (42.87, SE=11.5), and C (1.7399, SE=0.050) resulted in an R 2 of 0.9836 and residual SD of 83.7 g. Allometric (Y=A BWB), linear-quadratic and exponential (Y=exp (b0+b1BW+b2 (BW)2) functions of BW were fitted to the chemical component and amino acid mass data. Dry matter percentage of the ducks increased (P<0.01) with age. The protein content of the dry matter decreased (P<0.01) from day 1 to day 8 (69 to 58.2%) and then increased to 60% by d 29. Concentrations of several amino acids were affected (P<0.05) by age. The predicted accretion rates of Lys, Trp, and Met relative to protein accretion increased as age increased. The predicted daily accretion rates for major indispensable amino acids increased rapidly the first 5 d post-hatch and subsequently increased but at a decreasing rate to day 29 post-hatch. The relative growth rates of chemical components and indispensable amino acids were affected by age indicating that the nutrient requirements of ducks differ from day 1 to day 29 post-hatch. Compositional growth and amino acid accretion data can be used to model the nutrient requirements of ducks.

The following thesis will explore the contemporary meaning of ‘Place’ and the lost relationship between human sensitivity -both emotional and physical- and the setting, which together would form the very definition of a place, and will make an attempt to re-define this relationship. By returning to the basic definition of place, this paper emphasizes the fact that place without memory is simply space without meaning and that unlike places of our time that put little emphasis on the embodied memory, memory of place is experienced through not only mind but also the entire body. The paper will take a bottom-up approach where ‘Space’ as a fundamental element of ‘Place’ and its transformation to place is discussed. There will be a comprehensive discussion on place itself and the role and ability of embodied memory in creation of place. Each section will make an effort to consider the current circumstances of ‘Place’ and how they might be transformed to establish a relationship between embodied memory of space and the physical location. Here, senses, movement and basic orientation of the body will be discussed as elements empowering the embodied memory and having the ability to transform spaces–or non-places- of our time into place. Movement if not one of our five senses, inspires us to engage our whole body; we see, touch and smell what surrounds us, and also understand the setting in the sense that we engage or interact with it. The design project will explore the act of movement as the fundamental element of forming embodied memory of ‘Space’ and transforming it into ‘Place’. Element of path, which links two significant nodes - one known as a place and another a non-place- will be incorporated to represent the act of movement and its impact on creation of a ‘Place’.

Diachasmimorpha Longicaudata

The communication and reproduction of insects are driven by chemical sensing. During this process, chemical compounds are transported across the sensillum lymph to the sensory neurons assisted by different types of soluble binding proteins: odorant-binding proteins (OBPs); chemosensory proteins (CSPs); some members of ML-family proteins (MD-2 (myeloid differentiation factor-2)-related Lipid-recognition), also known as NPC2-like proteins. Potential transcripts involved in chemosensing were identified by an in silico analysis of whole-body female and male transcriptomes of the parasitic wasp Diachasmimorpha longicaudata. This analysis facilitated the characterization of fourteen OBPs (all belonging to the Classic type), seven CSPs (and two possible isoforms), and four NPC2-like proteins. A differential expression analysis by qPCR showed that eleven of these proteins (CSPs 2 and 8, OBPs 2, 3, 4, 5, 6, 9, 10, and 11, and NPC2b) were over-expressed in female antenna and two (CSP 1 and OBP 12) in the body without antennae. Foraging behavior trials (linked to RNA interference) suggest that OBPs 9, 10, and 11 are potentially involved in the female orientation to chemical cues associated with the host. OBP 12 seems to be related to physiological processes of female longevity regulation. In addition, transcriptional silencing of CSP 3 showed that this protein is potentially associated with the regulation of foraging behavior. This study supports the hypothesis that soluble binding proteins are potentially linked to fundamental physiological processes and behaviors in D. longicaudata. The results obtained here contribute useful information to increase the parasitoid performance as a biological control agent of fruit fly pest species.

AbstractUsing the notion of an elementary loop, Gebser and Schaub (2005. Proceedings of the Eighth International Conference on Logic Programming and Nonmonotonic Reasoning (LPNMR'05), 53–65) refined the theorem on loop formulas attributable to Lin and Zhao (2004) by considering loop formulas of elementary loops only. In this paper, we reformulate the definition of an elementary loop, extend it to disjunctive programs, and study several properties of elementary loops, including how maximal elementary loops are related to minimal unfounded sets. The results provide useful insights into the stable model semantics in terms of elementary loops. For a nondisjunctive program, using a graph-theoretic characterization of an elementary loop, we show that the problem of recognizing an elementary loop is tractable. On the other hand, we also show that the corresponding problem is coNP-complete for a disjunctive program. Based on the notion of an elementary loop, we present the class of Head-Elementary-loop-Free (HEF) programs, which strictly generalizes the class of Head-Cycle-Free (HCF) programs attributable to Ben-Eliyahu and Dechter (1994. Annals of Mathematics and Artificial Intelligence 12, 53–87). Like an HCF program, an HEF program can be turned into an equivalent nondisjunctive program in polynomial time by shifting head atoms into the body.

SummaryThe conventional radioisotope scanner has been used as a whole body counter. The background index of the system is 10.9 counts per minute per ml of sodium iodide crystal. The sensitivity and derived sensitivity parameters have been evaluated and found to be suitable for clinical studies. The optimum parameters for a single detector at two positions above the lying subject have been obtained. It has been found that for the case of 131I measurement it is possible to assay a source located at any point in the body with coefficient of variation less than 5%. To add to the versatility, a fixed geometry for in-vitro counting of large samples has been obtained. The retention values obtained by the whole body counter have been found to correlate with those obtained by in-vitro assay of urine and stool after intravenous administration of 51Cr-albumin.

Academic Debate

Over the past thirty years, academic debate over pornography in the discourses of feminism and cultural studies has foundered on questions of the performative and of the word's definition. In the polylogue of Droit de regards, pornography is defined as la mise en vente that is taking place in the act of exegesis in progress. (Wills's idiomatic English translation includes an ‘it’ that is absent in the French original). The definition in Droit de regards alludes to the word's etymology (writing by or about prostitutes) but leaves the referent of the ‘sale’ suspended. Pornography as la mise en vente boldly restates the necessary iterability of the sign and anticipates two of Derrida's late arguments: that there is no ‘the’ body and that performatives may be powerless. Deriving a definition of pornography from a truncated etymology exemplifies the prosthesis of origin and challenges other critical discourses to explain how pornography can be understood as anything more than ‘putting (it) up for sale’.

This essay seeks to dispel entrenched critical opinion regarding dance across Nietzsche's writings as representative of Dionysian intoxication alone. Taking as its prompt the riposte of Alain Badiou, ‘Nietzsche is miles away from any doctrine of dance as a primitive ecstasy’ and ‘dance is in no way the liberated bodily impulse, the wild energy of the body’, the essay uncovers the ties between dance and Apollo in the Nietzschean theory of art while qualifying dance's relation to Dionysus. Primarily through an analysis of The Dionysiac World View and The Birth of Tragedy, the essay seeks to illuminate enigmatic statements about dance in Nietzsche (‘in dance the greatest strength is only potential, although it is betrayed by the suppleness of movement’ and ‘dance is the preservation of orderly measure’). It does this through an elucidation of the specific function of dance in Nietzsche's interpretation of classical Greece; via an assessment of the difficulties associated with the Nietzschean understanding of the bacchanal; and lastly through an analysis of Nietzsche's characterization of dance as a symbol. The essay culminates in a discussion of dance's ties to Nietzschean life affirmation; here the themes of physico-phenomenal existence, joy and illusion in Nietzsche are surveyed.
