During vertebrate embryogenesis, the planar cell polarity (PCP) signalling pathway is responsible for cell movements essential for convergent extension during gastrulation, neural tube closure, neural crest cell migration, and heart morphogenesis. In the heart, the non-canonical Wnt/PCP pathway regulates cell polarity, cell shape, and cell dynamics during formation of the cardiac crescent and deployment of second heart field cardiac progenitors to the poles of the heart tube. PCP signalling is also essential for the establishment of left–right patterning in the early embryo. This chapter reviews our current understanding of PCP signalling in heart morphogenesis and how it affects the pathogenesis of congenital heart diseases.

This chapter talks about how Progressive women faced a number of challenges as they headed out on the campaign trail in 1948. Not only did Women for Wallace activists have to contend with Cold War politics, including debates about the role of Communists in the Progressive Party (PP), they also had to negotiate the competing rationales members claimed for women's political engagement. The feminisms that took root in the PP were most often shaped by debates about the grounds on which Progressive women should demand their right to political participation. Divisions within the Congress of American Women and Women for Wallace organizations were determined by the degree to which members relied upon notions of “difference” between men and women to claim their rights.

This chapter considers the law of nations (LN) and the perpetual peace projects (PPP), two intellectual traditions giving rise to an international theory aimed at regulating or abolishing the use of armed force. It examines the role of the LN and the PPP in the emergence of modern international law and of international organizations and peace movements, and how they influenced and were influenced by the rise of the modern European states. It charts the history of both traditions and the emergence of the state as the main player in internal and international politics before concluding with a discussion on the use of armed force concerning four main cases which were the subjects of considerable debate within both the LN and the PPP: war among states, the right to resist or to fight a revolution against an oppressive regime, humanitarian intervention, and the use of force against stateless indigenous populations.

Haemodynamic monitoring is a significant component in the management of critically-ill patients. Flow-directed pulmonary artery catheters (PAC) are a simple and rapid technique for measuring several continuous or intermittent circulatory variables. The PAC is helpful in diagnosis, guidance of therapy, and monitoring therapeutic interventions in various clinical conditions, including myocardial infarction and its complications, non-cardiogenic pulmonary oedema and severely ill patients.The catheter is inserted through a large vein. The PAC is advanced, after ballooninflation with 1.5 mL of air, through the right ventricle across the pulmonary valve and into the pulmonary artery (PA). Finally, the catheter is advanced to the ‘wedge’ position. The pulmonary artery wedge pressure (PAWP) is identified by a decrease in pressure combined with a characteristic change in the waveform. The balloon should then be deflated and the PA tracing should reappear. Direct measurements include central venous pressure, pulmonary artery pressure, and PAWP, which during diastole represents the left ventricular end-diastolic pressure and reflects left ventricular preload. Cardiac output can be measured by thermodilution technique. Other haemodynamic variables can be derived from these measurements. Absolute contraindications are rare. Relative contraindications include coagulopathy and conditions that increase the risk of arrhythmias.

This book pulls back the curtain on early constitutional conversations between citizens and officials in the People's Republic of China (PRC). Scholars have argued that China, like the former Soviet Union, promulgated constitutions to enhance its domestic and international legitimacy by opening up the constitution-making process to ordinary people, and by granting its citizens political and socioeconomic rights. But what did ordinary officials and people say about their constitutions and rights? Did constitutions contribute to state legitimacy? Over the course of four decades, the PRC government encouraged millions of citizens to pose questions about, and suggest revisions to, the draft of a new constitution. Seizing this opportunity, people asked both straightforward questions like “what is a state?”, but also others that, through implication, harshly criticized the document and the government that sponsored it. They pressed officials to clarify the meaning of words, phrases, and ideas in the constitution, proposing numerous revisions. Despite many considering the document “bullshit,” successive PRC governments have promulgated it, amending the constitution, debating it at length, and even inaugurating a “Constitution Day.” The book deals with all facets of this constitutional discussion, as well as its afterlives in the late 1950s, the Cultural Revolution, and the post-Mao era. It illuminates how the Chinese government understands and makes use of the constitution as a political document, and how a vast array of citizens—police, workers, university students, women, and members of different ethnic and religious groups—have responded.

This chapter illustrates how African American women remained active at both the highest levels of the Progressive Party (PP) and its base, where interracial grassroots networks attempted to bring the ideals of national figures like Eslanda Goode Robeson, Shirley Graham Du Bois, and Charlotta Bass to life. The American Labor Party (ALP)—which served as the PP organization of New York in 1948—was an important vehicle for women fighting racism and U.S. militarism in their local communities. Historians who have documented the ALP's important contributions to New York's early civil rights campaigns often overlook the significance of the party's linkage between peace, racial justice, and women's rights. An examination of the ALP, therefore, offers the opportunity to consider the challenges progressive women's networks encountered in the struggle to keep the hope of positive peace alive.

This chapter examines the nature of the parish churches of the Church of England, the respective roles of priest and people, and the rights and duties of the parochial church council (PCC), churchwardens and others. It first provides an overview of the parish structure before discussing the parish electoral roll and the annual parochial church meeting. It then considers the Parochial Church Councils, parochial property, the liability of the rector for repairs to the chancel, quinquennial inspection, and diocesan quota. It also describes pastoral schemes and orders, pastoral church building schemes, sharing of church buildings, ecumenical relations between the Church of England and other Churches, and churchwardens. Finally, it looks at other lay officers of the parish as well as non-parochial churches and chapels.

Each Concentrate revision guide is packed with essential information, key cases, revision tips, exam Q&As, and more. Concentrates show you what to expect in a law exam, what examiners are looking for, and how to achieve extra marks. Having begun with a consideration of the meaning of tort and the context of the ‘tort system’, Tort Law Concentrate covers the key elements of negligence: duty of care, breach of duty, and causation. Economic loss and psychiatric injury are specifically discussed. The book also explains the intentional torts: trespass to the person and to land as well as the tort in Wilkinson v Downton are covered, as is product liability. The family of nuisance torts, with their importance for environmental control are included, as is the key issue of remedies. This new edition includes coverage of recent case law, such as Barclays Bank plc v Various Claimants (2020) and Lachaux v Independent Print (2019). This edition has been fully updated in light of developments in the law, including the continuing impact of the Human Rights Act 1998 and the Consumer Rights Act 2015.

This chapter discusses the law on creditor claims in England. The English courts have recently considered the ranking and priority of creditors on a number of occasions. The differing classes of claims found in the judgment of Lord Neuberger PSC in Re Nortel GmbH best explain how the distinction between ‘insolvency claims’, ‘administration claims’, and ‘non-enforceable claims’ is reflected in the applicable English rules. With the exception of expenses and shareholders’ claims, all the claims listed by Lord Neuberger are ‘insolvency claims’ because they are all creditors’ claims which are referable to pre-proceeding obligations. The remainder of the chapter deals with insolvency claims, administration claims, and non-enforceable claims in turn. Each section describes: the definition and scope of the claim; rules for submission, verification, and satisfaction or admission of claims; ranking of claims; and voting and other participation rights in insolvency proceedings.

The book provides the first in-depth and empirically grounded analysis on the foundations and trajectories of gaining authority of the four Latin American and Caribbean regional economic courts: the Central American Court of Justice (CACJ), the Caribbean Court of Justice (CCJ), the Andean Tribunal of Justice (ATJ), and the Mercosur Permanent Review Court (PRC). While these courts were, on their terms, established to build common markets and to enforce trade liberalization, they have often developed bodies of jurisprudence in domains often not directly associated with regional economic integration. The CCJ has been most successful in the area of human and fundamental rights; the CACJ has addressed issues related to the enforcement of the rule of law in national legal arenas and long-standing border disputes between the countries of the region; the ATJ is an island of effective adjudication on intellectual property issues; and the PRC has significantly struggled to receive a significant number of cases to rule upon all together. The particular trajectories of the four Latin American and Caribbean Regional Economic Courts (RECs) suggest that there is no universal formula for success for these institutions and that their operational path is not necessarily a function of their formally delegated competences and/or of the will of the Member States, as it is often argued in mainstream legal and political science literature. Rather, local socio-political contextual factors—such as the historical legacies of a region, the interests and dynamics of socialization of legally and politically situated actors, the nature of national and regional politics, and legal culture—often play a far more decisive role in influencing the direction of RECs during and after their establishment.

This well-established and authoritative work is the most detailed reference source on the law relating to minority shareholders. As more and more legal emphasis is put on corporate governance, and as the influence of shareholder activism continues to grow, practitioners increasingly need a source of up-to-date and detailed information on the rights and remedies available to the minority. This is the only book to focus on this increasingly topical and important subject. This sixth edition features a new chapter on share purchase orders and valuation. There is expanded coverage of the relevant non-UK authorities, including cases from Hong Kong, Singapore, the British Virgin Islands, and Cayman. There is also more detailed analysis of shareholder agreements and related developments in contract law relevant to minority shareholders (e.g., arguments around implied terms and good faith). The new edition also covers significant developments in case law, such as Eclairs Group Ltd v JKX Oil & Gas plc.

A challenge to environmental protection and the jus post bellum framework is the rise in Private Security Companies and other Private Security Service Providers (PSCs). The marked increase in the outsourcing of vast amounts of operational and logistical work to PSCs have caused key issues around PSC oversight, regulation, and concern around civilian protection linked to environmental issues to arise. Using the Iraq (2003–11) and Afghanistan (2001–14) conflicts as examples, this chapter explores the growth of PSCs, their environmental performance, and reviews the adequacy of legal and policy frameworks that regulate PSCs to ensure the provision of adequate environmental protection as part of jus post bellum in order to contribute to sustainable peace. Areas of law explored include international humanitarian law, international human rights law, binding legislation and soft law specific to PSCs, contract litigation, corporate liability, state and non-state actor obligations in respect to PSCs, and shared responsibility.

This book reviews the first-hand experiences of men and women who provide a human perspective on issues that have shaped US engagement with China: politics and diplomacy, business and education, art and culture, journalism, law and human rights. It describes how, for them, China was more than just another place, it was an idea, a cause, a revolution, a civilization; some were born in China, others were motivated by curiosity and adventure; and some saw China as an existential threat, some as a socialist utopia, and others worked to improve US-China relations for non-ideological reasons. The book also chronicles Chinese Americans who wanted to help China overcome the poverty and humiliation of its past. Looming over the narratives presented in the book is the question of whether starkly different Chinese and Western worldviews could find common ground. Was it best to abide by Chinese norms, taking into account China’s unique history and culture? Or should individual civil and human rights be defended as universal? Would the PRC move in the direction of Western-style liberal democracy? Or was the Communist Party destined to continue on an authoritarian path? The figures in this book had distinctive answers to these questions. Their stories hold up a mirror to our two societies, helping to explain how we have arrived at the present moment.

Koffman & Macdonald’s Law of Contract provides a clear, academically rigorous, account of the contract law which is written in a style which makes it highly accessible to university students new to legal study.

[Introducción]. Con motivo de los 40 años transcurridos desde la Declaración de Alma-Ata, el 11 y 12 de diciembre de 2017 la Organización Panamericana de la Salud (OPS) convocó en Quito el Foro Regional “Salud Universal en el Siglo XXI: 40 años de Alma-Ata”. Como parte de este movimiento regional la Directora de la OPS, la Dra. Carissa F. Etienne tomó la iniciativa de crear una Comisión de Alto Nivel, denominada “Salud Universal en el Siglo XXI: 40 años de Alma-Ata”, presidida por la Dra. Michelle Bachelet y el Embajador Sr. Néstor Méndez, y conformada por un grupo interdisciplinario de expertos regionales. Entre ellos había representantes de la comunidad, la academia y actores políticos, como ex ministros de salud y líderes de sindicatos y movimientos de diferentes grupos sociales. El objetivo de la Comisión fue elaborar recomendaciones para la Directora de OPS que permitieran hacer efectivo el derecho a la salud de las personas, entendido como un derecho humano fundamental, a partir del análisis de los avances y los desafíos que tienen los sistemas de salud en la Región de las Américas. El presente documento refleja el posicionamiento de la Comisión en torno a la Atención Primaria de Salud (APS) y la búsqueda de soluciones para hacer efectivo el derecho a la salud, además del enfoque utilizado para orientar el debate, el análisis y las recomendaciones sobre cómo garantizar este derecho. El documento se basa en los reportes elaborados por cinco grupos temáticos: a) modelo de atención de salud, b) modelo institucional, c) modelo de financiamiento, d) salud y protección social y e) recursos humanos de salud, los cuales están disponibles como anexos a este informe. Estos grupos temáticos fueron liderados por los miembros de la Comisión, y reunieron a un gran número de expertos académicos y movimientos sociales de diferentes países de la Región. La Comisión presenta diez recomendaciones para lograr la salud para todas y todos en la Región de las Américas en el contexto del siglo XXI. [Introduction]. To mark the 40th anniversary of the Declaration of Alma-Ata, the Pan American Health Organization (PAHO) convened the Regional Forum “Universal Health in the 21st Century: 40 Years of Alma-Ata” on December 11-12, 2017, in Quito, Ecuador. As part of this regional movement, PAHO Director Dr. Carissa F. Etienne convened a High-Level Commission: Universal Health in the 21st Century: 40 Years of Alma-Ata, chaired by Dr. Michelle Bachelet and Ambassador Néstor Mendez, and made up of an interdisciplinary group of regional experts, including representatives from communities and academia, as well as political actors, such as former health ministers, trade union leaders, and representatives of different social movements. The objective of the Commission was to develop recommendations for the PAHO Director on how to give effect to the right to health as a fundamental human right, based on an analysis of the progress and challenges faced by health systems in the Region of the Americas. This document reflects the Commission’s position regarding primary health care (PHC), the search for solutions to ensure the right to health, and the approach taken in discussions, analysis, and recommendations on how to guarantee this right. It is based on reports prepared by the five thematic groups addressing: a) health care model, b) institutional model, c) financing model, d) health and social protection, and e) human resources for health (see annexes to the present report). The thematic groups were led by members of the Commission, bringing together a great number of academic experts and social movements from different countries in the Region. In this report, the Commission presents 10 recommendations for achieving health for all in the Region of the Americas in the 21st century.

Without assuming prior legal knowledge, books in the Directions series introduce and guide readers through key points of law and legal debate. Questions, diagrams, and exercises help readers to engage fully with each subject and check their understanding as they progress. This book explains the key topics covered on equity and trusts courses. The content of the text is designed to emphasise the relationship between equity, trusts, property, contract, and restitution to enable students to map out conceptual connections between related legal ideas. There is also a focus on modern cases in the commercial sphere to reflect the constantly changing and socially significant role of trusts and equity. The book starts by introducing equity and trusts. It then includes a chapter on understanding trusts, and moves on to consider capacity and formality requirements, certainty requirements, and the constitution of trusts. Various types of trusts are then examined such as purpose, charitable, and variation trusts. The book then describes issues related to trusteeship. Breach of trust is explained, as is informal trusts of land. There is a chapter on tracing, and then the book concludes by looking at equitable liability of strangers to trust and equitable doctrines and remedies. This new edition includes coverage of significant recent cases, including Patel v Mirza [2016], Supreme Court on the right to recover wealth transferred between parties to an illegal scheme; Burnden Holdings (UK) Ltd v Fielding [2018] UKSC 14; [2018] 2 WLR 885, Supreme Court on limitation of actions; Barnett v Creggy [2016], Court of Appeal on breach of trust and limitation of actions; Singha v Heer [2016], Court of Appeal on facts giving rise to declaration of trust; Clydesdale Bank plc v John Workman [2016], Court of Appeal on dishonest assistance in a breach of trust; Bathurst v Bathurst [2016], on variation of trusts; Newman v Clarke [2016], on fiduciary conflict of interest; RBC Trustees (CI) Ltd v Stubbs [2017], on rectification of a trust deed on the ground of mistake; Erlam v Rahman [2016] EWHC 111 and JSC Mezhdunarodniy Promyshlenniy Bank v Pugachev [2017] EWHC 2426, on ‘sham” trusts’. It also provides coverage of the 2017 Money Laundering, Terrorist Financing and Transfer of Funds Regulations (SI 2017/692 as well as the EU Fourth Money Laundering Directive ((EU) 2015/849), as amended by the The EU Fifth Money Laundering Directive ((EU) 2018/843)

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.
