Abstract:
The year is 1600. It is April and Japan’s iconic cherry trees are in full flower. A battered ship drifts on the tide into Usuki Bay in southern Japan. On board, barely able to stand, are twenty-three Dutchmen and one Englishman, the remnants of a fleet of five ships and 500 men that had set out from Rotterdam in 1598. The Englishman was William Adams, later to be known as Anjin Miura by the Japanese, whose subsequent transformation from wretched prisoner to one of the Shogun’s closest advisers is the centrepiece of this book. As a native of Japan, and a scholar of seventeenth-century Japanese history, the author delves deep into the cultural context facing Adams in what is one of the great examples of assimilation into the highest reaches of a foreign culture. Her access to Japanese sources, including contemporary accounts – some not previously seen by Western scholars researching the subject – offers us a fuller understanding of the life lived by William Adams as a high-ranking samurai and his grandstand view of the collision of cultures that led to Japan’s self-imposed isolation, lasting over two centuries. This is a highly readable account of Adams’ voyage to and twenty years in Japan and that is supported by detailed observations of Japanese culture and society at this time. New light is shed on Adams’ relations with the Dutch and his countrymen, including the disastrous relationship with Captain John Saris, the key role likely to have been played by the munitions, including cannon, removed from Adams’ ship De Liefde in the great battle of Sekigahara (September 1600), the shipbuilding skills that enabled Japan to advance its international maritime ambitions, as well as the scientific and technical support Adams was able to provide in the refining process of Japan’s gold and silver.

Abstract:
This chapter tracks the diffusion of Western-style athletic culture in Japan and Korea since the late nineteenth century. It argues that modern teach sport was introduced to Japan and Korea by British and American educators and Christian missionaries. Many Western team sports were introduced to North Asia by the YMCA. Japan sought excellence in Olympic sports before World War II as evidence of its modernity. Sport served in Korea as a mechanism for expressing anticolonial nationalism. After World War II, economic growth enabled both nations to allocate more resources to excellence in elite sport. Hosting the Asian Games and the Olympics were considered by both Japan and Korea as a stepping-stone to achieving first-class nation status and international recognition.

Abstract:
Asia’s film industries have undergone significant transformation in the last 30 years. From bilateral co-production agreements to pan-Asian financing, Asian cinema has assumed a regional identity beyond its constituent national cinemas. This book examines the dynamic industrial and cultural developments that have enabled greater co-operation and integration between Asia’s film industries. It brings a much-needed focus on how collaborative Asian film industries are affecting models of financing, distribution, exhibition and reception in the region and beyond.

Abstract:
This final chapter returns to the core argument given the fieldwork presented. It is made clear from the case of the digital street that the experience of an urban neighborhood gets filtered through social media. The chapter reviews the transformation of street life in Harlem during the study period based on the different ways that youth, adults, police, and other neighborhood actors used the digital street in relation to each other. The author remarks on the localization of the Internet from the fact that online space enabled residents to rework and control matters in neighborhood space. The chapter ends with key lessons for a service-oriented approach to youth on the street that utilizes the increased visibility and productive aspects of social media use.

Abstract:
After the middle of the nineteenth century, city clerks, social reformers, and journalists began to reflect about the effects of Berlin’s dynamic transformation. This chapter focuses on an influential strand of this literature in which authors claimed that the spread of new activities, such as visits to dance halls or seeking marriage through personal ads, resulted in the decline of people’s “feeling of morality” (sittliches Gefühl). The chapter demonstrates that it was important for contemporary authors to draw on the concept of feeling rather than other concepts of morality, as this enabled them to respond to the rising authority of the natural sciences. Since a number of observers described a feeling of morality as an important element that tied Berliners together as a community, its loss raised concern about the effects of urban change on the bodies and minds of the city’s inhabitants.

Abstract:
Since the disintegration of the Soviet Union, Baku has undergone a tremendous transformation. In this context, demographic trends for the last decade have been quite favourable toward the development of Baku, with a constant increase in population due to the high net-in migration from the rural areas of Azerbaijan. Consequently, it is not surprising that Baku exerts a disproportionately significant influence on the national economy. The city continues to be the leading recipient of investment, most of which is funneled into the construction industry. The post-Soviet transition toward a market economy has enabled Baku to make tremendous progress in urban development and to become one of the fastest growing cities in the region. This chapter looks at the development pattern of Baku, and its attempts to emulate Gulf cities. It will try to answer the question of whether Baku will be able to copy the pattern of the “Pearl of UAE” successfully, or if it will fail because of indigenous and exogenous factors.

Abstract:
Sino-Japanese literature stands out among the Chinese-style literatures of East Asia for the wealth of texts preserved from the early period, its complex symbiosis with a flourishing vernacular tradition, and its pervasive reliance on gloss-reading techniques of Chinese texts (kundoku). These techniques allowed the transformation of Chinese texts into Japanese sound, syntax, and morphology and enabled a distinctive linguistic and creative distance from continental literary production. This chapter surveys the literary culture and production of Early Japan (Asuka, Nara and Heian Periods, seventh through twelfth centuries). After introducing the debates about the varied nomenclature of the corpus of “Sino-Japanese Literature” (kanbun; also called Japanese Literature in Chinese), it sketches the contexts of the emergence of Sino-Japanese textual culture and literature in Japan and gives an overview of major texts in their cultural context. It concludes with reflections on what students of China can learn from Sino-Japanese Literature.

Full text
Abstract:
This book draws on the latest research on the human brain to show how it differs strikingly from those of other animals in its structure and function at molecular and cellular level. It argues that this ‘shift’, enlarging the brain, giving it greater flexibility and enabling higher functions such as imagination, was driven by tool use, but especially by the development of one remarkable tool—language. The complex social interaction brought by language opened up the possibility of shared conceptual worlds, enriched with rhythmic sounds and images that could be drawn on cave walls. This transformation enabled modern humans to generate an exceptional human consciousness, a sense of self that arises as a product of our brain biology and the social interactions we experience. Linking early work by the Russian psychologist Lev Vygotsky to the findings of modern neuroscience, the book also explores how language, culture, and society mediate brain function, and what this view of the human mind may bring to our understanding and treatment of mental illness.

Abstract:
The panda did not become an official symbol of the PRC in a debate over worthy animal emblems, but emerged as a representation of China in various contexts by fulfilling specific needs of the nation. The giant panda became broadly relevant to human society when it was deemed a scientifically interesting animal. International research on pandas has probed most every aspect of the animal’s being. The Chinese government’s persistent endorsement of wide-ranging scientific work on the giant panda over the course of PRC history reflects the tremendous value the Chinese state has placed on the panda as an animal. What is most striking about the giant panda historically is not its curiosity as an oddity in the animal kingdom, but that it stands apart as a cute national symbol. Unlike the more commonly majestic and intimidating choices of eagle or lion, the panda elicits affection. The panda’s gentle allure has been central to its transformation into a powerful political tool. The traits that inspire anthropomorphism have enabled the panda to hold a special position as a diplomat, not only between China and the rest of the world, but also between the human and animal world.

Full text
Abstract:
The Ottoman Army had a significant effect on the history of the modern world and particularly on that of the Middle East and Europe. This study, written by a Turkish and an American scholar, is a revision and corrective to western accounts because it is based on Turkish interpretations, rather than European interpretations, of events. As the world’s dominant military machine from 1300 to the mid-1700’s, the Ottoman Army led the way in military institutions, organizational structures, technology, and tactics. In decline thereafter, it nevertheless remained a considerable force to be counted in the balance of power through 1918. From its nomadic origins, it underwent revolutions in military affairs as well as several transformations which enabled it to compete on favorable terms with the best of armies of the day. This study tracks the growth of the Ottoman Army as a professional institution from the perspective of the Ottomans themselves, by using previously untapped Ottoman source materials. Additionally, the impact of important commanders and the role of politics, as these affected the army, are examined. The study concludes with the Ottoman legacy and its effect on the Republic and modern Turkish Army. This is a study survey that combines an introductory view of this subject with fresh and original reference-level information. Divided into distinct periods, Uyar and Erickson open with a brief overview of the establishment of the Ottoman Empire and the military systems that shaped the early military patterns. The Ottoman army emerged forcefully in 1453 during the siege of Constantinople and became a dominant social and political force for nearly two hundred years following Mehmed’s capture of the city. When the army began to show signs of decay during the mid-seventeenth century, successive Sultans actively sought to transform the institution that protected their power. The reforms and transformations that began frist in 1606successfully preserved the army until the outbreak of the Ottoman-Russian War in 1876. Though the war was brief, its impact was enormous as nationalistic and republican strains placed increasing pressure on the Sultan and his army until, finally, in 1918, those strains proved too great to overcome. By 1923, Mustafa Kemal Atatürk emerged as the leader of a unified national state ruled by a new National Parliament. As Uyar and Erickson demonstrate, the old army of the Sultan had become the army of the Republic, symbolizing the transformation of a dying empire to the new Turkish state make clear that throughout much of its existence, the Ottoman Army was an effective fighting force with professional military institutions and organizational structures.

Abstract The aeroplane played a small but significant role in India’s transformation from colony to republic. Through the prism of aviation, both civil and military, this book traces the story of India’s journey from the Second World War to the emergence of India as a sovereign state. Drawing on archives in India and the United Kingdom, untapped personal collections, and newspaper reports it points to the critical impact of aviation on the shaping of modern South Asia. Control of aviation enabled the Indian state to survive the twin crises of partition and the war in Kashmir. The aeroplane also served as a potent symbol of modernity. The strategic and ideological importance of aircraft was not lost on other contenders for power in South Asia. The Indian princes and Pakistan both also invested substantially in aviation with a view to entrenching their sovereignty. The book makes two key arguments. First, a study of the state’s relationship with aviation reveals that independent India conceptualized sovereignty in ways that diverged radically from its colonial predecessor, stressing the importance of ruptures over continuities in explaining decolonization. Second, that aviation was critical to securing and legitimating independent India. Indeed, the indispensability of aircraft would be confirmed by the independent Indian government’s decision in 1953 to nationalize aviation, heralding an era of near-total state control of aviation. This book is the first comprehensive history of aviation in India and makes important interventions in a number of fields including histories of technology, warfare, politics, transport, and law.

Abstract:
This chapter investigates the role of the Internet in reshaping learning and education. It describes distinctions between formal education, where the Internet has made few inroads, and informal learning, where it seems to have excelled. Moreover, the chapter explores how the Internet has – via the World Wide Web – enabled an expansion in informal and incidental learning opportunities. Online courses are dealt through learning management systems, or virtual learning environments. The Internet's contribution to formal learning has been considerably less transformative than its contribution to informal learning. The Internet is not primarily an educational tool, but it self-evidently offers unique and unparalleled scope for the exploration of new forms of exploration and collaboration in the development and sharing of knowledge.

Abstract:
This chapter tries to show what practical difference it makes if one adopts the approach developed in the foregoing chapters. It focuses on the work that political theory and political theorists might do in support of an effective real-world response to injustice. Much of the conflict around injustice is ideological—it arises from conflicting values, ideas, and interpretations. When an ideology becomes dominant or hegemonic, its key concepts become decontested, making injustice seem natural or normal. To contest this requires a form of counterhegemonic politics, politics designed to challenge the prevailing ideological views and proposing alternative viewpoints. Its success depends on building countervailing power through discursive political engagement, efforts enabled by the work of articulation and translation. The ultimate aim of transformative democratic politics is to establish a reflexive, open-ended, and continual process of repair, renewal, and (re)generation.

Abstract:
From iPods to EZPass technology to YouTube to eGovernment initiatives, the impact of technology is changing our lives more and more each day. This book, a counterpart to a Maryland Public Television documentary, chronicles how and why and shows ways people can take advantage of the revolution in their personal and professional lives. As technology expert Henry C. Lucas, Jr., argues, the fundamentals of business and the economy—not to mention the details of daily life—are changing in every market, in every industry, and in every nation. This book explores the most significant of these technology-enabled transformations to help readers understand and appreciate the opportunities and threats presented by a new, technology-driven global economy. Among other things, Inside the Future demonstrates that: -A revolution in technology is transforming business and the way individuals live and work. -It's essential to adapt to change. Resisting technological advances is futile, and countries or people that fall behind in technology may never catch up. -The U.S. needs to prepare current and future workers for an economy that incorporates technology in every business process, an economy in which there are almost no constraints from time and place, and an economy in which most hierarchical organizations disappear. -The future competitiveness of the country depends on our ability to innovate and implement change enabled by technology. This revolution is leaving no person or organization untouched. From business to education and healthcare, the digitization and mobilization of every process affects us all. Yet this isn't a book about technology, but one that shows how people and organizations can adapt technology to transform their businesses as well as create a more productive, satisfying personal life. Readers will gain a new awareness of how leading organizations apply IT to create transformations, and how they can use technology to improve their lives, remain competitive in the workforce, and survive in this new age of constant change and re-invention.

Abstract:
This chapter covers the multidisciplinary literature on the protection of personal information in the online world, which extends back to the origins of social research on computing, and addresses the link between key structures of the Internet and the literatures on privacy and surveillance. Then, it turns to the literature on the role of international, legal, self-regulatory, and technological policy instruments in protecting personal information online. The nature of the Internet is entirely consistent with the metaphor of the ‘surveillant assemblage’. The Internet has become a fundamentally ‘surveillance-ready’ technology, and is becoming deeply integrated into the structures of social life. The rise of Internet-enabled surveillance and information control is significant. The story of privacy and surveillance is episodic and reflective of quite frenzied attempts to come to grips with unprecedented technological transformations in the light of the most recent scandal or controversy.

This chapter tracks the global circulation of gospel music, a movement enabled in part by the transnational record industry, noting in particular the ways some audiences in the African Diaspora receive and participate in the music in continuity with African American religious practice in the United States. A key interest is the way gospel music reflects religiosity and cultural experience and the transformations that can disrupt the link between these elements in global performances. The chapter traces performances and historical moments that show an encounter with the global in the careers of pioneering gospel performers, including Mahalia Jackson and Rosetta Tharpe. It then describes and analyzes the author’s experience as “performer and culture bearer” of gospel music in two transnational sites: collaborative performances in Malawi and Cuba. The author concludes that the comprehensive integrity of gospel music is presented most coherently when the music is mediated through the lens of both cultural and religious identity.

Abstract:
As a Communist state bordering Vietnam, China actively supported Ho Chi Minh’s wars against France in 1950–1954 and then America in 1965–1970. This book uses new Communist sources to offer an unprecedented Chinese military perspective on the Vietnam War. By documenting the level of Chinese military assistance to Vietnam, it reveals the extent to which the Chinese support of Ho’s military and political objective in the wars was a crucial and indispensable factor in North Vietnam’s victory. The study offers an overview and the particulars of Chinese aid to Ho’s army, or PAVN, in terms of training, weaponry, logistics, advisors, and technology during its transformative years of 1950–1956 in depth and detail based on a foundation of multiple documentary sources, memoirs, interviews, and secondary sources both in China and in Vietnam. With Chinese assistance, the PAVN experienced three important transformative changes from a peasant, rebellion force to a regular, national army. In retrospect, international Communist support to North Vietnam proved to be the decisive edge that enabled the PAVN, or NVA, to survive the American Rolling Thunder bombing campaign and helped the NLF, also known as the Viet Cong, to prevail in the war of attrition and eventually defeat South Vietnam. An international perspective may help students and the public in the West to gain a better understanding of America’s long war.

Abstract:
The triumph of the Cuban Revolution gave the Communist Party a monopoly over both politics and the mass media. However, with the subsequent global proliferation of new information and communication technologies, Cuban citizens have become active participants in the worldwide digital revolution. While the Cuban internet has long been characterized by censorship, high costs, slow speeds, and limited access, this volume argues that since 2013, technological developments have allowed for a fundamental reconfiguration of the cultural, economic, social, and political spheres of the Revolutionary project. The essays in this volume cover various transformations within this new digital revolution, examining both government-enabled paid public web access and creative workarounds that Cubans have designed to independently produce, distribute, and access digital content. Contributors trace how media ventures, entrepreneurship, online marketing, journalism, and cultural e-zines have been developing on the island alongside global technological and geopolitical changes. As Cuba continues to expand internet access and as citizens challenge state policies on the speed, breadth, and freedom of that access, Cuba’s Digital Revolution provides a fascinating example of the impact of technology in authoritarian states and transitional democracies. While the streets of Cuba may still belong to Castro’s Revolution, this volume argues that it is still unclear to whom Cuban cyberspace belongs.

Abstract:
In 2017, Maureen Pytlik graduated from Ottawa’s Carleton University with degrees major in both clarinet performance and mathematics. Her curriculum also included advanced music theory studies and West African drumming and dance. She describes her West African dance experiences as transformative. “I was quite happy to open up and be awkwardly uncoordinated,” she relates, “because it was something that created a lot of group bonding in a way. Feeling part of the group was very important to me because having Asperger’s means it’s not something that I experience easily.” African dance, and drumming too, helped Maureen to navigate a dichotomy which has been difficult for her to manage in her life, and one that she identifies closely with having Asperger’s: the conflicting pulls of competing desires for control and freedom. “I am pulled in these two different directions,” she acknowledges. “My modes of being can fluctuate between the two styles of having control and experiencing freedom, but I have a hard time (as with any polar opposites) hovering in the middle between them without gravitating toward one extreme or the other at any given time.” Music and dance, especially of the West African variety, have enabled her to move closer to achieving that elusive balance.

Full text
Abstract:
La Nijinska: Choreographer of the Modern is the first biography of ballet’s premier female choreographer and a pioneer of the modern tradition in ballet. Overshadowed in life and legend by her brother Vaslav Nijinsky, Bronislava Nijinska had a far longer and more productive career. An architect of twentieth-century neoclassicism, she experienced the transformative power of the Russian Revolution and created her greatest work—Les Noces—under the influence of its avant-garde. Many of her ballets rested on the probing of gender boundaries, a mistrust of conventional gender roles, and the heightening of the ballerina’s technical and artistic prowess. A prominent member of Russia Abroad, she worked with leading figures of twentieth-century art, music, and ballet, including Stravinsky, Diaghilev, Poulenc, Alexandra Exter, Natalia Goncharova, Frederick Ashton, Alicia Markova, and Maria Tallchief. She was also a remarkable dancer in her own right with a bravura technique and powerful stage presence that enabled her to perform an unusually broad repertory. Finally, she was the author of an acclaimed volume of memoirs in addition to a major treatise on movement. Nijinska’s career sheds new light on the modern history of ballet and of modernism more generally, recuperating the memory of lost works and forgotten artists, many of them women. But it also reveals the sexism pervasive in the upper echelons of the early and mid-twentieth-century ballet world and the barriers that still confront ballet’s women choreographers.

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.
