Acute mesenteric ischemia is a life-threatening vascular emergency associated with a very high mortality rate. In the setting of necrotic bowel, the current standard of care requires a laparotomy with bowel resection and surgical or endovascular revascularization of the superior mesenteric artery. Unfortunately, mesenteric bypass confers high perioperative mortality, in some reports up to 45%. A hybrid technique that employs an exploratory laparotomy, catheterization of the distal superior mesenteric artery, and stent deployment across the atherosclerotic lesion was first described in 2004 for the treatment of acute-on-chronic mesenteric ischemia. This chapter describes the appropriate clinical indications, the technical aspects of performing this hybrid procedure, as well as the challenges and common pitfalls encountered.

This handbook examines cutting-edge developments in research and applications of small or mesoscopic superconductors, offering a glimpse of what might emerge as a giga world of nano superconductors. Contributors, who are eminent frontrunners in the field, share their insights on the current status and great promise of small superconductors in the theoretical, experimental, and technological spheres. They discuss the novel and intriguing features and theoretical underpinnings of the phenomenon of mesoscopic superconductivity, the latest fabrication methods and characterization tools, and the opportunities and challenges associated with technological advances. The book is organized into three parts. Part I deals with developments in basic research of small superconductors, including local-scale spectroscopic studies of vortex organization in such materials, Andreev reflection and related studies in low-dimensional superconducting systems, and research on surface and interface superconductivity. Part II covers the materials aspects of small superconductors, including mesoscopic effects in superconductor–ferromagnet hybrids, micromagnetic measurements on electrochemically grown mesoscopic superconductors, and magnetic flux avalanches in superconducting films with mesoscopic artificial patterns. Part III reviews the current progress in the device technology of small superconductors, focusing on superconducting spintronics and devices, barriers in Josephson junctions, hybrid superconducting devices based on quantum wires, superconducting nanodevices, superconducting quantum bits of information, and the use of nanoSQUIDs in the investigation of small magnetic systems.

Chapter 6 places the analysis developed in this book in a broader normative perspective, focusing on a series of challenges and dilemmas associated with the transformation in the logic of security provision examined in the previous chapters. It pays particular attention to the ways in which the particular dynamics of commercialization of security provision have involved departures from principles of transparency and democratic accountability, and the problems associated with such departures in countries with long histories of anti-democratic governance. Finally, the chapter reflects on the difficulties of promoting liberal-democratic standards of “good governance” in contexts in which (in)security is performed by hybrid networks of security entrepreneurs that blur the boundaries between licit/illicit activities.

Chapter 9 turns to further epistemic barriers for decision makers: the problems of (nonmoral) ignorance and (nonmoral) uncertainty. The concepts of “ignorance” and “uncertainty” are elucidated, the problem of uncertainty is defined, and it is argued that the problem of ignorance should be treated as a special case of the problem of uncertainty. The three salient attempts to solve the problem are the Pragmatic, Austere, and Hybrid approaches. Combined solutions to the problem of error and the problem of uncertainty are explored, and it is argued that the only feasible approaches marry the Austere Response to the problem of error with the Hybrid Response to the problem of uncertainty in a two-tier system. The top-tier code provides the correct theoretical account of right and wrong, while the lower-tier rules provide associated decision-guides. Consistency requires that different normative terms be used by the top-tier rules and by the lower-tier rules.

The introduction launches an investigation into how martial arts differentiate themselves from violence, countering the commonplace assumptions that modern, hybrid sport fighting is a descent into brutality and that traditional martial arts transcend conflict. This section addresses the central paradox of combat sport training, that practicing actions associated with violence—punches, kicks, takedowns—can render a martial artist calmer, more focused, and more peaceful. The chapter illustrates how frames and devices associated with agonistic play allow fight sports to contend with the very risks they engage. Investigating the differences between fighting, as consensual and mutual, and violence, as non-consensual and one-sided, this chapter puts forward the central claim of Risk, Failure, Play: that play consists of techniques and practices that enable us to manage fraught realities with intelligence.

Shockley writes creatively in response to an inscription written on the side of the jar associated with the title of the collection. As a contemporary black woman and as a literary critic and a poet herself, Shockley seeks out her multifaceted relatedness to the person and legacy of Dave the Potter. In this hybrid of creative and scholarly writing, Shockley uses the format of the letter to imaginatively reply directly to “Dave.” In the process, Shockley transforms the terms of historical inquiry to better suit the diasporic terms of her relation to a “him” who is never finally in the past nor an object of impersonal history.

Several psychophysical and neuropsychological investigations suggest that the processing of number and spatial information is strongly associated. A popular account argues that this association has its origin in the underlying mental representation of numbers taking the form of a horizontally-orientated mental number line, which is isomorphic to the representation of physical lines. Recently, however, several alternative explanations have been put forward. We describe those theories and argue that no current account is on itself able to explain the full range of observations. To do this, a hybrid account is proposed which takes into account the underlying representation, but emphasizes the processing mechanisms required by the task at hand.

This chapter analyzes the film career of D. A. Pennebaker. Pennebaker's key word is “interesting.” In numerous interviews, he has referred to events, subjects, and topics that have a certain “attractive” quality, in the sense that they demand attention, as interesting. In this way, he has insisted that a filmmaker “must shoot only what interests you.” His diversity of interesting films encompasses hybrid forms in which components of “documentary” mix with heightened dramatic elements associated with fiction film. These films include Daybreak Express (1953–57), an avant-gardist look at New York City; Jane (1962), a study of the actress Jane Fonda; Depeche Mode 101 (1989), and Only the Strong Survive (2002).

Sleep paralysis is an experience of being temporarily unable to move or talk during the transitional periods between sleep and wakefulness: at sleep onset or upon awakening. The feeling of paralysis may be accompanied by a variety of vivid and intense sensory experiences, including mentation in visual, auditory, and tactile modalities, as well as a distinct feeling of presence. This chapter discusses a variety of sleep paralysis experiences from the perspective of enactive cognition and cultural neurophenomenology. Current knowledge of neurophysiology and associated conditions is presented, and some techniques for coping with sleep paralysis are proposed. As an experience characterized by a hybrid state of dreaming and waking, sleep paralysis offers a unique window into phenomenology of spontaneous thought in sleep.

The putative explanatory role of mathematics is further pursued in this chapter in the context of the so-called indispensability argument. Our conclusion here is that the possibility of mathematical entities acquiring some explanatory role is not well motivated, even within the framework of an account of explanation that might be sympathetic to such a role. We also consider the claim that certain scientific features have a hybrid mathematico-physical nature, again in the context of a specific example, namely that of spin, but we argue that the assertion of hybridity also lacks strong motivation and comes with associated metaphysical costs. Furthermore, such claims fail to fully grasp the details of the interrelationships between mathematical and physical structures in general and the distinction between the mathematical formalism and its interpretation in particular.

This introductory chapter traces a process of cultural transformation that, beginning in the early decades of the twentieth century, led to the rise after World War II of the phenomenon called slapstick modernism. Manifesting itself in literature, (underground) film, and popular music, the rise of slapstick modernism signaled the coalescence in cultural practice of the artistic experimentation associated with high modernism, and the socially disruptive lunacy linked to the comic film genre. However, the concept of slapstick modernism has yet to receive adequate theorization; this is partly due to the insufficiency of the terms initially used to capture the specificity of this new, hybrid cultural entity. Slapstick modernism had no manifesto of the sort that mobilized the various avant-garde ventures of the early decades of the twentieth century.

This chapter provides an overview of key surveillance theories and their implications for law and regulation. It presents three stages of theories that characterize changes in thinking about surveillance in society and the disciplining, controlling, and entertaining functions of surveillance. Beginning with Bentham’s Panopticons and Foucault’s panopticism to discipline surveillees, surveillance theory then develops accounts of surveillant assemblages and networked surveillance that control consumers and their data doubles, to finally branch out to theorizing current modes of surveillance, such as sousveillance and participatory surveillance. Next, surveillance technologies and practices associated with these stages are discussed. The chapter concludes by highlighting the implications for regulators and lawmakers who face the challenge of regulating converging, hybrid surveillant infrastructures and assemblages, both in their context-dependent specificity and in their cumulative effect on citizen/consumers.

This chapter presents an account of color constancy that explains a well-known division in the data from color-constancy experiments: So-called “paper matches” exhibit a much higher level of constancy than so-called “hue-saturation matches.” It argues that the visual representation of objective color is the representation of something associated with a function from viewing circumstances to color appearances. Thus, a relatively robust constancy in the representation of objective color is perfectly consistent with a relatively less robust level of constancy in color appearance. The account also endorses Hilbert’s idea that we can represent the color of the illumination on a surface as well as the color of the surface itself. Finally, the chapter addresses an objection to the hybrid view that notes our capacity to make very fine-grained distinctions between the objective colors of surfaces.

The crisis parameters of the development of the ukrainian-russian border society are analyzed in the coordinates of the civilizational borderland, marked by the "intersection" of controversial socio-cultural markers, identification matrices, local values, meanings and symbols. Using the conceptual principles of transitology, the strategies of social transformations and cultural practices in the border space, the mechanisms of identification confrontations and mental confrontations are considered. The impact of borderland on spatial and socio-cultural dynamics and the increase in the risks of the emergence of states of "existential transitivity" and "hybrid identity" in the border society are assessed. It is proven that modern challenges associated with the russian-ukrainian war require systematic monitoring of the mental consequences of destabilization of the security environment in the border region, development of conceptual principles for the formation of a consolidation identity and representation of the conditions for its implementation, development of algorithms for minimizing identity conflicts in the context of civilizational transformations and long-term existential crises.

The key features of glomerular diseases—haematuria, proteinuria, loss of glomerular filtration rate, and hypertension—were recognized in the nineteenth century, and some earlier, but Richard Bright is usually given credit for synthesizing the concepts of renal disease, and glomerulonephritis came under the heading of Bright’s disease for almost a century. Separation into different types was based on first clinical syndromes, but in the early twentieth century, pathological description was improving and with the introduction of percutaneous renal biopsies in the 1950s, in the 1960s histopathological definitions assumed the ascendancy. A unifying classification of glomerular disease remains work in progress. Current classifications are pathologically based but increasingly include the results of other investigations (including genotype and a variety of immunological and other tests). This chapter follows this pragmatic, hybrid approach, categorizing glomerular disease by pattern on renal biopsy except where aetiological factors are clearly identified (e.g. HIV nephropathy), or associated multisystem disease is defined (e.g. lupus nephritis), or the immunopathogenesis is well characterized (e.g. antiglomerular basement membrane disease).

This entry in the Food Culture around the World series helps those in the United States understand the new immigrants from Central America who have brought their food cultures with them. Food Culture in Central America illustrates the unique foodways of the region in depth–and in English–for the first time. Important foods and ingredients, techniques, and lore associated with food preparation are surveyed. Typical meals eaten at home are presented, with attention to the cultural context in which those meals take place, including regional or national differences. The book also examines various meal settings–street vendors, modest comedors, and fancy restaurants. The role of food in common festivals and life cycle rituals is explored as well, including Christmas, Semana Santa, and Quincineras. Author Michael R. McDonald emphasizes the living process of "metatezation," referring to the use of the traditional metate, a stone platform used to grind ingredients, resulting in the unique flavors and textures of the cuisines. The process echoes the concept of "mestizaje," the intense hybrid mixture of identities throughout Latin America, which is also explained.

The resurgence of asexualism in Germany in the nineteenth century coincided with the Naturphilosophie movement associated with Romanticism which arose in reaction to mechanical models of the universe, among them Baron d’Holbach’s. Johann Gottlieb Fichte, a Kant disciple, claimed that the “absolute ego” creates it’s own reality, which we mistake for the “real world”. Friedrich Wilhelm Schelling, the “philosopher king” of the Romantics, attempted a balance between Fichte’s subjective idealism and Johann Wolfgang von Goethe’s (relative) objectivism. In general, nature philosophers granted equal weight to reason and to the imagination, and adopted a pantheistic theology, influenced by Baruch Spinoza. Franz Joseph Schelver believed the production of seeds was a vegetative process. August Henschell dismissed Koelreuter’s hybrids as artifacts resulting from experimental damage. He thought the release of pollen freed the spiritual essence of the plant from base matter. Georg Wilhelm Friedrich Hegel also challenged the sexual theory of plants.

The Bantu languages are in some sense remarkably uniform (subject, verb, order (SVO) basic word order, noun classes, verbal morphology), but this extensive language family also show a wealth of morphosyntactic variation. Two core areas in which such variation is attested are subject and object agreement. The book explores the variation in Bantu subject and object marking on the basis of data from 75 Bantu languages, discovering striking patterns (the Relation between Asymmetry and Non-Doubling Object Marking (RANDOM), and the Asymmetry Wants Single Object Marking (AWSOM) correlation), and providing a novel syntactic analysis. This analysis takes into account not just phi agreement, but also nominal licensing and information structure. A Person feature, associated with animacy, definiteness, or givenness, is shown to be responsible for differential object agreement, while at the same time accounting for doubling vs. non-doubling object marking—a hybrid solution to an age-old debate in Bantu comparative morphosyntax. It is furthermore proposed that low functional heads can Case-license flexibly downwards or upwards, depending on the relative topicality of the two arguments involved. This accounts for the properties of symmetric object marking in ditransitives (for Appl), and subject inversion constructions (for v). By keeping Agree constant and systematically determining which featural parameters are responsible for the attested variation, the proposed analysis argues for an emergentist view of features and parameters (following Biberauer 2018, 2019), and against both Strong Uniformity and Strong Modularity.

Focusing on four East European polities—Bosnia, Serbia, Bulgaria, and Romania—this book examines the dynamics and implications of processes of commercialization of security that have occurred following the collapse of communist regimes. These processes have been central to post-communist liberalization, and have profoundly shaped those states and their integration into European institutional structures and global economic and political circuits. They have also affected—and been shaped by—the behavior and power of regional and global actors (e.g. European institutions, regional and global corporations) in Eastern Europe. By virtue of the fact that they combine in complex ways local, national, regional, and global dynamics and actors, processes of security commercialization in the former Eastern bloc can be seen as instances of “glocalization.” Several aspects of security commercialization are particularly important. To begin with, private actors—specifically private security companies (PSCs)—have been reconstituted as partial agents of public power. As such, they have come to be systematically involved in performing security practices traditionally associated with the state. In addition, a potent commercial logic has come to permeate public security institutions. This has led to redefinition of the relationship between the state and its population in ways that defy conventional wisdom about the role of the state, and pose difficult normative challenges. More broadly, processes of security commercialization in Eastern Europe, which involve important performative dimensions, have led to the emergence of complex, hybrid networks of security providers that transcend domestic/international, public/private boundaries and behave, in many ways, as entrepreneurs.

Creativity is at the vanguard of contemporary capitalism, valorized as a form of capital in its own right. It is the centrepiece of the vaunted ‘creative economy’, and within the latter, the creative industries. But what is economic about creativity? How can creative labour become the basis for a distinctive global industry? And how has the solitary artist, a figment of Romantic thought, become the creative entrepreneur of twenty-first-century economic imagining? Such questions have long provoked scholars interested in economics, sociology, management and law. This book offers a fresh approach to the theoretical problems of cultural economy, through a focus on intellectual property (IP) within the creative industries. IP and its associated rights (IPR) are followed as they journey through the creative economy, creating a hybrid IP/IPR that shapes creative products and configures the economic agency of creative producers. The book argues that IP/IPR is the central mechanism in organizing the market for creative goods, helping to manage risk, settle what is valuable, extract revenues, and protect future profits.. Most importantly, IP/IPR is crucial in the dialectic between symbolic and economic value on which the creative industries depend: IP/IPR hold the creative industries together. The book is based on a detailed empirical study of creative producers in the UK, extending sociological studies of markets to an analysis of the UK’s creative industries. It makes an important, empirically grounded contribution to debates around creativity, entrepreneurship, and precarity in creative industries and will be of interest to scholars and policymakers alike.

Donkeys carried Christ into Jerusalem while in Greek myth they transported Hephaistos up to Mount Olympos and Dionysos into battle against the Giants. They were probably the first animals that people ever rode, as well as the first used on a large-scale as beasts of burden. Associated with kingship and the gods in the ancient Near East, they have been (and in many places still are) a core technology for moving people and goods over both short and long distances, as well as a supplier of muscle power for threshing and grinding grain, pressing olives, raising water, ploughing fields, and pulling carts, to name just a few of the uses to which they have been put. Yet despite this, they remain one of the least studied, and most widely ignored, of all domestic animals, consigned to the margins of history like so many of those who still depend upon them. Spanning the globe and extending from the donkey's initial domestication up to the present, this book seeks to remedy this situation by using archaeological evidence, in combination with insights from history and anthropology, to resituate the donkey (and its hybrid offspring such as the mule) in the unfolding of human history, looking not just at what donkeys and mules did, but also at how people have thought about and understood them. Intended in part for university researchers and students working in the broad fields of world history, archaeology, animal history, and anthropology, but it should also interest anyone keen to learn more about one of the most widespread and important of the animals that people have domesticated.

As we write these words, the COVID-19 pandemic has become part of our lives in a much more controlled way. For instance, some of our habits have changed and we are able to resume our activities in the way of a “new normal,” returning to social contact with family, friends, and colleagues. In returning to a life without the constraint of the virus at such a high level, the academy tries to resume its rituals, including scholarly events. Email boxes and physical boards at universities are once again filling up with calls for submission of abstracts for congresses, seminars, and workshops. As these events are happening again, academia seems to be reflecting on the pros and cons of onsite scientific events. While acknowledging the importance of such scientific events and their potential for strengthening scholarly communities and collaborations, many academics have begun questioning the real impact of being physically present. This questioning seems to be based on several factors. On the one hand, it is clear that universities have been increasingly devaluing academics’ presence in congresses (unless by invitation). They allocate less funding for these activities, especially for those academics who wish to attend an event without presentation. With no presentation, institutions devalue attendance in performance appraisal processes. Increasingly, academic institutions value publications (indexed, despite some positive movement seeking to counter the tyranny of the “publish or perish” motto), and an academics ability to raise funding. Yet, not all congresses are associated with publication processes in indexed journals or proceedings. Books of abstracts (once edited by any congress) are almost extinct, namely because of their devaluation by institutes of higher learning (and funding entities). On the other hand, the massive and necessary use of online scientific events in 2020 and 2021 allowed us to realize that it is possible, efficient, and effective to hold these events in a format different from the traditional one. The internet offers versatility and more and more congresses are now offered online or in hybrid formats. These formats allow academics to overcome financial and physical complications caused by in-person scholarly events. Academics can request less funding and, at the same time, mitigate concerns of acceptance without presentations, covering classes while away, or having to supplement university sponsorship with personal funds. At some universities, funding comes after attendance regardless of availability of those funds and academics are asked to pay registration fee, plane tickets, and lodging with the expectation of being reimbursed upon return. This is particularly challenging given the present economic situation around the globe. At the same time, while physically at the event and away from families, work continues to accumulate for academics. They then must wade through this excess upon returning home, adding to an already excessive workload. This makes maintaining a work-life balance challenging. We at New Trends in Qualitative Research (NTQR) believe it is particularly relevant to discuss this topic within the context of the release of NTQR Volume 11. NTQR is an indexed journal associated with international scientific events in the field of qualitative research - Congreso Ibero-Americano en Investigación Cualitativa (CIAIQ) and the World Conference on Qualitative Research (WCQR). Specifically, the volume that we edit here aggregates works that, having been originally presented at WCQR2022 (held in an online format), went through a double-blind review process. This volume, annually edited (as WCQR is an annual event), allows us, as editors, to condense a diverse set of qualitative research work, focusing on different topics, and with different methodological designs. And, our concern as editors has always been to assure the quality of the published works, namely through a careful review and editing process. We do not know if we are ready to give up our physical presence at scientific events. But, with opportunities such as online presentations and online publishing venues, we may now be much more judicious in this presence. We may now take time to ponder the relevance of investing in attending a scientific event, and selecting (hand-drawn) two or three events per year, at most. WCQR has a strong emphasis in the building of a scientific community (in this case, bonded by the interest in qualitative research), reconciling physical and online presence, and is associated with quality journals. These aspects help academics to select it as one of the events where it is important to be present. Sincerely, The Editors

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.
