Wagner, Peter D. Gas exchange assessment in the critically ill. Oxford University Press, 2016. http://dx.doi.org/10.1093/med/9780199600830.003.0076.

Full text
Abstract:
Chapter 75 laid out the basic principles that govern pulmonary gas exchange, a step necessary for the appropriate application and interpretation of common clinical tests of gas exchange. The present chapter discusses the several common tests and indices used to analyse and quantify gas exchange abnormalities in critically-ill patients. There is special emphasis on inherent limitations of each technique, as well as on ways to minimize technical and experimental errors when the necessary measurements are made. Limitations and errors are considered to be of major clinical importance because, while the measurements and indices themselves are easy to obtain, and have been in routine use for many years, serious errors of interpretation can occur if the limitations and common errors are not appreciated and allowed for. In particular, it is pointed out that factors external to the lungs can dramatically change arterial oxygenation in the critically-ill patient. This means that not all changes in gas exchange reflect changes in lung pathology. It is not uncommon for arterial PO2 to change without change in lung disease severity when external factors such as metabolic rate, cardiac output, and blood temperature change.

Full text
Abstract:
Since the early 1990s, at least forty-five initiatives have been mounted to improve the environmental and social performance of the mining industry. Many changes in the formal legal and regulatory systems have also been introduced. However, no systematic approach has been adopted to test whether this effort is making a difference. Without such monitoring of success, the tension between companies, communities, and governments regarding the role of mining in society will continue. This chapter makes the case for using ‘contribution analysis’ to fill this gap, a systematic means to assess and track mining’s contribution to human and ecosystem well-being over the full project and product life cycles. This is a higher test than current practice. It brings out a fuller picture of the positives and negatives of natural resources and their management, provides greater opportunity for the perspectives of all interests to be heard, and is fairer.

The conclusion suggests how the book’s theoretical and empirical findings can inform our understanding of the relationship between states and civil society more generally, and teases out the implications of this study for future research on different kinds of politicization and policy formation. It also examines the implications of trade battles for democratic practices and movement mobilization. It describes how NAFTA has become a litmus test for candidates, and how opposition to NAFTA and to the loss of jobs to foreign countries may have impacted the 2016 presidential election. Although too many variables are in play to determine all the effects of NAFTA, the chapter describes some of those effects on jobs, manufacturing, and inequality.

Full text
Abstract:
Was it communism or socialism that succumbed in 1989? Was communism dead in 1989, when the ‘Sinatra Doctrine’ (‘each does it his own way’) replaced the Brezhnev Doctrine in East Central Europe? Or did the patient agonise until the official dismemberment of the Soviet Union in 1991? Twenty-seven countries share a communist past in Europe and Asia. Of the surviving five, not all would pass the ‘Leninist test’. Which legacies affect post-communist systems has been an issue under debate since shortly after the fall of the Old Regimes. Claus Offe pointed out that post-communist regimes are faced with a ‘dilemma of simultaneity’, amounting to a ‘triple transition’: the process of having to cope concomitantly with unconsolidated borders, democratisation, and property redistribution. While other authors have often wondered which legacies ‘count’ in post-communism (those of communism itself or the ante-communist heritage), it is Herbert Kitschelt's merit to have pointed out that the modes of communist rule have been in turn influenced by historical antecedents.

Full text
Abstract:
Chapter 9 describes the food stamp program as inseparable from the romantic certainties that gave rise to the Personal Responsibility and Work Opportunities Reconciliation Act of 1996 (PRWORA). It focuses on Temporary Assistance for Needy Families (TANF). The characteristics of food stamp recipients and welfare recipients generally and the performance of welfare programs—objective social need and response—are less germane to the American people than their beliefs in virtue. Those beliefs are sustained by faith in an imagined tradition more than by social reality or even the effects that those beliefs have on the conditions of need. Food stamp benefits, taken together with all means-tested welfare programs, are inadequate to routinely raise recipients out of poverty. Serious deprivation remains widespread. Rather than relieve poverty, these public welfare programs ceremonialize the tenets of policy romanticism.

Full text
Abstract:
According to Adams’ thesis the probability of a conditional is the conditional probability of the consequent given the antecedent. According to Stalnaker semantics, a conditional is true at a world just in case its consequent is true at all closest antecedent worlds to the original world. The chapter argues that Adams’ thesis and Stalnaker semantics are ways of cashing out the same ‘Ramsey test’ idea. Unfortunately, a well-known class of triviality theorems shows that Adams’ thesis and Stalnaker semantics are incompatible. Stefan Kaufmann has proposed (for reasons largely independent of the triviality theorems) a revised version of Adams’ thesis, which the chapter calls Kaufmann’s thesis. The chapter proves that combining Kaufmann’s thesis with Stalnaker semantics leads to ‘local triviality’ results, which seem just as absurd as the original triviality results for Adams’ thesis.

Full text
Abstract:
This chapter reviews Fodor’s contribution to the epic Chomsky-Piaget Royaumont debate. The issue that was under discussion was a familiar one, namely, what psychological processes underlie concept learning. Piaget thought concept learning involved the formation and confirmation of hypotheses that a learner generates through the construction and organization of stimuli gathered from the environment, and modifying them when they proved to be inconsistent. However, Fodor pointed out a fundamental flaw in this theory: it is silent about the origin of the concepts used in generating the hypotheses. Fodor argued that in order for these hypotheses to be tested, let alone generated, they needed to have been readily available to the learner, suggesting that all primitive concepts are innate, and that concept acquisition relies on the process of triggering these concepts that are innately available to the learner, and not through construction by means of progressive guesses and trial-and-error.

Full text
Abstract:
This book presents a new neurocognitive theory of dreams that documents the similarities of dreaming to waking thought, demonstrates that personal psychological meaning can be found in a majority of dream reports, has a strong developmental dimension based on excellent longitudinal and cross-sectional studies carried out in sleep labs with children ages 3–15, locates the neural substrate for dreaming in the same brain network active during mind-wandering and daydreaming, and marshals the evidence that shows it is very unlikely that dreaming has any adaptive function. These claims are based on five different sets of descriptive empirical findings that were developed between the late 1950s and the first sixteen years of the twenty-first century. All of these findings were unanticipated by scientific dream researchers and then resisted to varying degrees by dream theorists for a variety of reasons. The first five chapters spell out the theory and the evidence for it without any discussion or criticism of past theories. The next two chapters present detailed criticisms of two major alternative theories. The penultimate chapter presents evidence that it is very unlikely that dreaming has any adaptive function in the evolutionary sense of the term, although humans have invented uses for dreams in religious and healing rituals. In that regard, dreaming has an emergent function in culture that was invented in the course of history due to human cognitive capacities. The final chapter presents a general agenda for future research using new methodologies to test all of the neurocognitive hypotheses.

Full text
Abstract:
To date, most network research contains one or more of five major problems. First, it tends to be atheoretical, ignoring the various social theories that contain network implications. Second, it explores single levels of analysis rather than the multiple levels out of which most networks are comprised. Third, network analysis has employed very little the insights from contemporary complex systems analysis and computer simulations. Foruth, it typically uses descriptive rather than inferential statistics, thus robbing it of the ability to make claims about the larger universe of networks. Finally, almost all the research is static and cross-sectional rather than dynamic. Theories of Communication Networks presents solutions to all five problems. The authors develop a multitheoretical model that relates different social science theories with different network properties. This model is multilevel, providing a network decomposition that applies the various social theories to all network levels: individuals, dyads, triples, groups, and the entire network. The book then establishes a model from the perspective of complex adaptive systems and demonstrates how to use Blanche, an agent-based network computer simulation environment, to generate and test network theories and hypotheses. It presents recent developments in network statistical analysis, the p* family, which provides a basis for valid multilevel statistical inferences regarding networks. Finally, it shows how to relate communication networks to other networks, thus providing the basis in conjunction with computer simulations to study the emergence of dynamic organizational networks.

Abhishek, Abhishek, and Michael Doherty. Investigations of calcium pyrophosphate deposition. Oxford University Press, 2016. http://dx.doi.org/10.1093/med/9780199668847.003.0051.

Full text
Abstract:
Joint aspiration and microscopic examination of the aspirated synovial fluid remains the gold standard for the diagnosis of calcium pyrophosphate crystal deposition (CPPD). If synovial fluid aspiration is not feasible, plain radiography and/or ultrasound scanning may be used to detect chondrocalcinosis (CC) which predominantly occurs due to calcium pyrophosphate (CPP) crystals, and this can be used as a diagnostic surrogate for CPPD as suggested by the EULAR Task Force. Acute CPP crystal arthritis often associates with a brisk acute phase response (elevated C-reactive protein (CRP) and/or erythrocyte sedimentation rate (ESR), plasma viscosity) and neutrophilia. A mildly raised CRP and/or ESR may be present in chronic CPP crystal inflammatory arthritis. On the contrary, asymptomatic CC, or CPPD with osteoarthritis does not cause raised acute phase reactants. As CPPD most commonly occurs due to increasing age and osteoarthritis, investigations to screen for underlying metabolic abnormalities should be carried out in those with early-onset CPPD (under 55 years), or in those with florid polyarticular CC. As hyperparathyroidism gets more common with ageing its presence should be specifically sought in all age groups. Tests for other predisposing metabolic conditions should only be carried out in the presence of specific clinical features. Genotyping for mutations, especially in the ANKH gene, may be warranted in those with a family history of premature CPPD and no evidence of inherited metabolic predisposition, but such testing is unavailable to most clinicians.

Full text
Abstract:
This book marks out a modernist counter-tradition. The book proceeds from an anachronism common to Italian- and English-language literature and cinema: a fascination with outmoded, paradigmatically pre-modern educational forms that persists long after they are displaced in modernizing, reform-minded pedagogical theories. Old Schools shows that these old-school teaching techniques organize key works by Walter Pater, Giovanni Pascoli, James Joyce, Pier Paolo Pasolini, and Glauber Rocha. All of these figures oppose ideologies of progress by returning to and creatively reimagining the Latin class long since left behind by progressive educators. Across the political spectrum, advocates of progressive education, from Jean-Jacques Rousseau to John Dewey and Giovanni Gentile, had targeted Latin in particular. The dead language—taught through time-tested techniques including memorization, recitation, copying out, and other forms of repetition and recall—needed to be updated or eliminated, reformers argued, so that students could breathe free and become modern, achieving a break with convention and constraint. By contrast, the works that Old Schools considers valorize instruction’s outmoded techniques, even at their most cumbersome and conventional. Like the Latin class to which they return, these works produce constraints that feel limiting but that, by virtue of that very limitation, invite valuable resistance. As they turn grammar drills into verse and repetitious lectures into voiceovers, they find unlikely resources for creativity and critique in the very practices that progressive reformers sought to clear away.

Full text
Abstract:
‘He began to feel the danger of paying Elizabeth too much attention’. Pride and Prejudice , one of the most famous love stories of all time, has also proven itself as a treasured mainstay of the English literary canon. With the arrival of eligible young men in their neighbourhood, the lives of Mr. and Mrs. Bennet and their five daughters are turned inside out and upside down. Pride encounters prejudice, upward-mobility confronts social disdain, and quick-wittedness challenges sagacity. Misconceptions and hasty judgements bring heartache and scandal, but eventually lead to true understanding, self-knowledge, and love. It’s almost impossible to open Pride and Prejudice without feeling the pressure of so many readers having known and loved this novel already. Will you fail the test - or will you love it too? As a story that celebrates more unflinchingly than any of Austen’s other novels the happy meeting-of-true-minds, and one that has attracted the most fans over the centuries, Pride and Prejudice sets up an echo chamber of good feelings in which romantic love and the love of reading amplify each other.

Abstract:
Muir Gray, Anne Mackie and Angela Raffle have been at the forefront of achieving improvements in UK screening over recent years, and they bring a wealth of experience to this non-technical introductory guide covering all aspects of screening. As USA expert Gilbert Welch describes it, this book is “A readable yet encyclopaedic guide to screening: its history, its key design elements, its implementation and policy challenges… A must read for clinicians, managers, and policy makers who would like to assist Raffle Mackie and Gray in achieving their goal: ‘to sort out the mess’.” The first four chapters deal with concepts, methods and evidence, explaining what screening is and how it is evaluated. Chapters five to eight describe practical aspects, for example how to make policy, and how to deliver screening to a high standard. The book includes numerous examples and real-life case histories, giving important reminders of the need to be vigilant for the hidden influence of commercial incentives and ‘bad science’ if we are to achieve best value health and healthcare. A comprehensive glossary makes medical terms accessible to all, and each chapter concludes with a summary and self-test questions. Reference is made to the UK National Health Service, a leader in screening, but the book is internationally relevant because the principles of good screening apply in any setting. The controversies, paradoxes, uncertainties, and ethical dilemmas of screening are explained in a balanced way.

Abstract:
Almost no systematic theorizing is generality-free. Scientists test general hypotheses; set theorists prove theorems about every set; metaphysicians espouse theses about all things regardless of their kind. But how general can we be? Do we ever succeed in theorizing about ABSOLUTELY EVERYTHING in some interestingly final, all-caps-worthy sense of ‘absolutely everything’? Not according to generality relativism. In its most promising form, this kind of relativism maintains that what ‘everything’ and other quantifiers encompass is always open to expansion: no matter how broadly we may generalize, a more inclusive ‘everything’ is always available. The importance of the issue comes out, in part, in relation to the foundations of mathematics. Generality relativism opens the way to avoid Russell’s paradox without imposing ad hoc limitations on which pluralities of items may be encoded as a set. On the other hand, generality relativism faces numerous challenges: What are we to make of seemingly absolutely general theories? What prevents our achieving absolute generality simply by using ‘everything’ unrestrictedly? How are we to characterize relativism without making use of exactly the kind of generality this view foreswears? This book offers a sustained defence of generality relativism that seeks to answer these challenges. Along the way, the contemporary absolute generality debate is traced through diverse issues in metaphysics, logic, and the philosophy of language; some of the key works that lie behind the debate are reassessed; an accessible introduction is given to the relevant mathematics; and a relativist-friendly motivation for Zermelo–Fraenkel set theory is developed.

Full text
Abstract:
During the past 30 years the Catholic bishops of the United States have captured the national headlines with their statements on nuclear disarmament and economic justice, their struggles to address sexual abuse by clergy, their concerns about abortion and religious freedom, and their defense of refugees and immigrants. The nearly 200 bishops leading local dioceses, though, are a varied mix of Church leaders. In 2016 all of the bishops were surveyed with an eye to better understanding who are the bishops as individuals (their background, education, and experiences), what are their day-to-day activities, their challenges and satisfactions as Church leaders, how they manage their dioceses, and how they speak out on public issues. The data are enriched by frequent quotes and anecdotes from the interviewed bishops. During the past 25 years the Church has gone from Pope John Paul II to Benedict XVI to Pope Francis, and the Catholic Church in the United States, along with its bishops, are dramatically different. The bishops of the United States have had their leadership tested by the sex abuse scandals, the movement of Catholics from the Northeast and Midwest to the South and West, and the arrival of more Catholic immigrants than they have seen in a century along with the ongoing decline in the number of priests and sisters serving the Catholic community. This book provides a unique and comprehensive view of who the bishops are, where they are from, and how they are leading the Church in the United States in the era of Pope Francis.

Full text
Abstract:
The Early Music revival has had far-reaching consequences on how music of the past is performed, both by specialists and non-specialists. This timely book is a practical step-by-step course of lessons for violinists and violists in both these categories, covering the interpretation, technique, culture, and historical background of the Baroque violin repertoire. Written by a violinist and teacher specializing in Baroque music over many years, it guides readers from the basics (how to hold the violin) to Bach, via music from a wide variety of styles. Avoiding obscure musicological jargon, it is eminently readable and accessible. Packed with information, detailed observations on the music under discussion, and relevant quotations from historical and contemporary sources, it covers everything the Baroque violin student should know and may be considered the equivalent of two to three years of individual lessons. The book contains over 100 exercises devised for and tested on students over the years. The author’s holistic approach is evident through the exercises aimed at bringing out the individual voice of each student, and his insistence that what happens within, the identification and manipulation of affects, is a vital part of successful performance. Imitating the voice, both spoken and sung, is a constant theme, beginning with the simple device of playing words. There are fifty lessons, including five Ornamentation Modules and ones on specific topics: temperament, rhetoric, the affects, and so on. All the music, transcribed for both violin and viola, is downloadable from the website, where there is also a series of videos.

Abstract:
Bones are multifunctional passive organs of movement that supports soft tissue and directly attached muscles. They also protect internal organs and are a reserve of calcium, phosphorus and magnesium. Each bone is covered with periosteum, and the adjacent bone surfaces are covered by articular cartilage. Histologically, the bone is an organ composed of many different tissues. The main component is bone tissue (cortical and spongy) composed of a set of bone cells and intercellular substance (mineral and organic), it also contains fat, hematopoietic (bone marrow) and cartilaginous tissue. Bones are a tissue that even in adult life retains the ability to change shape and structure depending on changes in their mechanical and hormonal environment, as well as self-renewal and repair capabilities. This process is called bone turnover. The basic processes of bone turnover are: • bone modeling (incessantly changes in bone shape during individual growth) following resorption and tissue formation at various locations (e.g. bone marrow formation) to increase mass and skeletal morphology. This process occurs in the bones of growing individuals and stops after reaching puberty • bone remodeling (processes involve in maintaining bone tissue by resorbing and replacing old bone tissue with new tissue in the same place, e.g. repairing micro fractures). It is a process involving the removal and internal remodeling of existing bone and is responsible for maintaining tissue mass and architecture of mature bones. Bone turnover is regulated by two types of transformation: • osteoclastogenesis, i.e. formation of cells responsible for bone resorption • osteoblastogenesis, i.e. formation of cells responsible for bone formation (bone matrix synthesis and mineralization) Bone maturity can be defined as the completion of basic structural development and mineralization leading to maximum mass and optimal mechanical strength. The highest rate of increase in pig bone mass is observed in the first twelve weeks after birth. This period of growth is considered crucial for optimizing the growth of the skeleton of pigs, because the degree of bone mineralization in later life stages (adulthood) depends largely on the amount of bone minerals accumulated in the early stages of their growth. The development of the technique allows to determine the condition of the skeletal system (or individual bones) in living animals by methods used in human medicine, or after their slaughter. For in vivo determination of bone properties, Abstract 10 double energy X-ray absorptiometry or computed tomography scanning techniques are used. Both methods allow the quantification of mineral content and bone mineral density. The most important property from a practical point of view is the bone’s bending strength, which is directly determined by the maximum bending force. The most important factors affecting bone strength are: • age (growth period), • gender and the associated hormonal balance, • genotype and modification of genes responsible for bone growth • chemical composition of the body (protein and fat content, and the proportion between these components), • physical activity and related bone load, • nutritional factors: – protein intake influencing synthesis of organic matrix of bone, – content of minerals in the feed (CA, P, Zn, Ca/P, Mg, Mn, Na, Cl, K, Cu ratio) influencing synthesis of the inorganic matrix of bone, – mineral/protein ratio in the diet (Ca/protein, P/protein, Zn/protein) – feed energy concentration, – energy source (content of saturated fatty acids - SFA, content of polyun saturated fatty acids - PUFA, in particular ALA, EPA, DPA, DHA), – feed additives, in particular: enzymes (e.g. phytase releasing of minerals bounded in phytin complexes), probiotics and prebiotics (e.g. inulin improving the function of the digestive tract by increasing absorption of nutrients), – vitamin content that regulate metabolism and biochemical changes occurring in bone tissue (e.g. vitamin D3, B6, C and K). This study was based on the results of research experiments from available literature, and studies on growing pigs carried out at the Kielanowski Institute of Animal Physiology and Nutrition, Polish Academy of Sciences. The tests were performed in total on 300 pigs of Duroc, Pietrain, Puławska breeds, line 990 and hybrids (Great White × Duroc, Great White × Landrace), PIC pigs, slaughtered at different body weight during the growth period from 15 to 130 kg. Bones for biomechanical tests were collected after slaughter from each pig. Their length, mass and volume were determined. Based on these measurements, the specific weight (density, g/cm3) was calculated. Then each bone was cut in the middle of the shaft and the outer and inner diameters were measured both horizontally and vertically. Based on these measurements, the following indicators were calculated: • cortical thickness, • cortical surface, • cortical index. Abstract 11 Bone strength was tested by a three-point bending test. The obtained data enabled the determination of: • bending force (the magnitude of the maximum force at which disintegration and disruption of bone structure occurs), • strength (the amount of maximum force needed to break/crack of bone), • stiffness (quotient of the force acting on the bone and the amount of displacement occurring under the influence of this force). Investigation of changes in physical and biomechanical features of bones during growth was performed on pigs of the synthetic 990 line growing from 15 to 130 kg body weight. The animals were slaughtered successively at a body weight of 15, 30, 40, 50, 70, 90, 110 and 130 kg. After slaughter, the following bones were separated from the right half-carcass: humerus, 3rd and 4th metatarsal bone, femur, tibia and fibula as well as 3rd and 4th metatarsal bone. The features of bones were determined using methods described in the methodology. Describing bone growth with the Gompertz equation, it was found that the earliest slowdown of bone growth curve was observed for metacarpal and metatarsal bones. This means that these bones matured the most quickly. The established data also indicate that the rib is the slowest maturing bone. The femur, humerus, tibia and fibula were between the values of these features for the metatarsal, metacarpal and rib bones. The rate of increase in bone mass and length differed significantly between the examined bones, but in all cases it was lower (coefficient b <1) than the growth rate of the whole body of the animal. The fastest growth rate was estimated for the rib mass (coefficient b = 0.93). Among the long bones, the humerus (coefficient b = 0.81) was characterized by the fastest rate of weight gain, however femur the smallest (coefficient b = 0.71). The lowest rate of bone mass increase was observed in the foot bones, with the metacarpal bones having a slightly higher value of coefficient b than the metatarsal bones (0.67 vs 0.62). The third bone had a lower growth rate than the fourth bone, regardless of whether they were metatarsal or metacarpal. The value of the bending force increased as the animals grew. Regardless of the growth point tested, the highest values were observed for the humerus, tibia and femur, smaller for the metatarsal and metacarpal bone, and the lowest for the fibula and rib. The rate of change in the value of this indicator increased at a similar rate as the body weight changes of the animals in the case of the fibula and the fourth metacarpal bone (b value = 0.98), and more slowly in the case of the metatarsal bone, the third metacarpal bone, and the tibia bone (values of the b ratio 0.81–0.85), and the slowest femur, humerus and rib (value of b = 0.60–0.66). Bone stiffness increased as animals grew. Regardless of the growth point tested, the highest values were observed for the humerus, tibia and femur, smaller for the metatarsal and metacarpal bone, and the lowest for the fibula and rib. Abstract 12 The rate of change in the value of this indicator changed at a faster rate than the increase in weight of pigs in the case of metacarpal and metatarsal bones (coefficient b = 1.01–1.22), slightly slower in the case of fibula (coefficient b = 0.92), definitely slower in the case of the tibia (b = 0.73), ribs (b = 0.66), femur (b = 0.59) and humerus (b = 0.50). Bone strength increased as animals grew. Regardless of the growth point tested, bone strength was as follows femur > tibia > humerus > 4 metacarpal> 3 metacarpal> 3 metatarsal > 4 metatarsal > rib> fibula. The rate of increase in strength of all examined bones was greater than the rate of weight gain of pigs (value of the coefficient b = 2.04–3.26). As the animals grew, the bone density increased. However, the growth rate of this indicator for the majority of bones was slower than the rate of weight gain (the value of the coefficient b ranged from 0.37 – humerus to 0.84 – fibula). The exception was the rib, whose density increased at a similar pace increasing the body weight of animals (value of the coefficient b = 0.97). The study on the influence of the breed and the feeding intensity on bone characteristics (physical and biomechanical) was performed on pigs of the breeds Duroc, Pietrain, and synthetic 990 during a growth period of 15 to 70 kg body weight. Animals were fed ad libitum or dosed system. After slaughter at a body weight of 70 kg, three bones were taken from the right half-carcass: femur, three metatarsal, and three metacarpal and subjected to the determinations described in the methodology. The weight of bones of animals fed aa libitum was significantly lower than in pigs fed restrictively All bones of Duroc breed were significantly heavier and longer than Pietrain and 990 pig bones. The average values of bending force for the examined bones took the following order: III metatarsal bone (63.5 kg) <III metacarpal bone (77.9 kg) <femur (271.5 kg). The feeding system and breed of pigs had no significant effect on the value of this indicator. The average values of the bones strength took the following order: III metatarsal bone (92.6 kg) <III metacarpal (107.2 kg) <femur (353.1 kg). Feeding intensity and breed of animals had no significant effect on the value of this feature of the bones tested. The average bone density took the following order: femur (1.23 g/cm3) <III metatarsal bone (1.26 g/cm3) <III metacarpal bone (1.34 g / cm3). The density of bones of animals fed aa libitum was higher (P<0.01) than in animals fed with a dosing system. The density of examined bones within the breeds took the following order: Pietrain race> line 990> Duroc race. The differences between the “extreme” breeds were: 7.2% (III metatarsal bone), 8.3% (III metacarpal bone), 8.4% (femur). Abstract 13 The average bone stiffness took the following order: III metatarsal bone (35.1 kg/mm) <III metacarpus (41.5 kg/mm) <femur (60.5 kg/mm). This indicator did not differ between the groups of pigs fed at different intensity, except for the metacarpal bone, which was more stiffer in pigs fed aa libitum (P<0.05). The femur of animals fed ad libitum showed a tendency (P<0.09) to be more stiffer and a force of 4.5 kg required for its displacement by 1 mm. Breed differences in stiffness were found for the femur (P <0.05) and III metacarpal bone (P <0.05). For femur, the highest value of this indicator was found in Pietrain pigs (64.5 kg/mm), lower in pigs of 990 line (61.6 kg/mm) and the lowest in Duroc pigs (55.3 kg/mm). In turn, the 3rd metacarpal bone of Duroc and Pietrain pigs had similar stiffness (39.0 and 40.0 kg/mm respectively) and was smaller than that of line 990 pigs (45.4 kg/mm). The thickness of the cortical bone layer took the following order: III metatarsal bone (2.25 mm) <III metacarpal bone (2.41 mm) <femur (5.12 mm). The feeding system did not affect this indicator. Breed differences (P <0.05) for this trait were found only for the femur bone: Duroc (5.42 mm)> line 990 (5.13 mm)> Pietrain (4.81 mm). The cross sectional area of the examined bones was arranged in the following order: III metatarsal bone (84 mm2) <III metacarpal bone (90 mm2) <femur (286 mm2). The feeding system had no effect on the value of this bone trait, with the exception of the femur, which in animals fed the dosing system was 4.7% higher (P<0.05) than in pigs fed ad libitum. Breed differences (P<0.01) in the coross sectional area were found only in femur and III metatarsal bone. The value of this indicator was the highest in Duroc pigs, lower in 990 animals and the lowest in Pietrain pigs. The cortical index of individual bones was in the following order: III metatarsal bone (31.86) <III metacarpal bone (33.86) <femur (44.75). However, its value did not significantly depend on the intensity of feeding or the breed of pigs.
