Property in body parts and products of the human body

An intriguing question, which until recently had not been directly explored by the courts, is the extent to which English law recognises body parts and products of the human body as property capable of ownership. Although the common law currently recognises no general property in a dead body (and only limited possessory rights in respect of it), this apparent “no-property rule” provides no justification, it is submitted, for denying proprietary status to parts or products of a living human body. The recent decision of the Court of Appeal in Yearworth v. North Bristol NHS Trust ([2009] EWCA Civ 37) lends strong support to the view that genetic material (as the product of a living human body) is capable of ownership, at least in the context of a claim in the tort of negligence and bailment. This article examines the various issues by reference to both English and Commonwealth authority.

Jackson v JH Watson Property Investment Ltd.

Comments on the Chancery Division decision in Jackson v JH Watson Property Investment Ltd on whether a landlord was liable in nuisance to a long leaseholder in respect of damage caused to the demised property by a building defect which pre-dated the grant of the lease or whether the principle of caveat lessee applied. Considers whether the defect amounted to "disrepair" within the meaning of the landlord's repairing covenant.

Property development: Appraisal and finance

The book provides an overview to the context of property development so that academics, students and professionals can examine the stages of development in the process - from initial consideration, to site finding, general appraisal, valuation, funding, construction and marketing, with a focus on two key areas of the process: appraisal and finance. The Second Edition reflects the developing research interests of the authors by putting property development and appraisal in a wider economic environment and the appraisal process was treated in a more holistic manner. Secondly, more case studies were included and the chapters framed with clear objectives key terms and summaries. Thirdly, this edition examined in more detail the property development and appraisal process in relation to sustainability and other key issues such as climate change, the changing financial environment, planning design and global influences. Research on appraisal techniques is incorporated in chapters 3-5. Research on property finance based on the original Property Lending Surveys carried out by the author and incorporated in other texts (Property Finance, 1994, 2003) is included in chapters 6-8. Research on property companies and their capital structures in included in chapter 8. Analysis of the relationship between sustainability and design is included in chapter 9. This is a key text in the area of property development, sales of the First Edition and Second Edition have been in the thousands globally to academics, students and practitioners.

The valuation of property investments

In the seventh edition, the book has been updated and revised to reflect changes in the market, the development of appraisal methods and the subsequent changes in professional practice. The intial overview in Part I of the book, The Economic and Legal Framework, has been revisd to show the present position. Changes in appraisal techniques based on the research of the authors have been incorporated in Part II on Investment Valuation. Revisions have also been made in part II, again based on the research activities of the authors, which examines Investment Appraisal.The serves a number of purposes. First, it provides a critical examination of valuation techniques, with particular reference to the investment method of valuation. Second, it supplies practising valuers and appraisers with more effective data, information and techniques to enable them to carry out their valuations, appraisals and negotiations in an increasily competitive field. Finally, it provides assistance to students and academics in understanding the context of and a range of approaches to the valuation and appraisal of property investments. This book has been a key text in property investment appraisal for more than 30 years, it has sold many thousands of copies globally to academics, students and practitioners.

Effect of machine dependence on wall failure property measurements, Jenike versus an annular shear tester

Annular, ring or torsional shear testers are commonly used in bulk solids handling research for the purpose of powder characterisation or equipment design. This paper reports from a DEFRA sponsored project which aims to develop an industrial powder flow-ability tester, (based on the annular shear tester) that is economic to buy and quick and easy to use in trained but unskilled hands. This paper compares the wall failure loci measured with an annular shear cell with measurements obtained using the accepted standard wall friction tester, the Jenike shear cell. These wall failure loci have been measured for several bulk solids which range from fine cohesive powders to free-flowing granular materials, on a stainless steel 304 2B wall surface.

Unbiased Linear Property Estimation For Spheres From Sections Exhibiting Overprojection And Truncation

In the biological sciences, stereological techniques are frequently used to infer changes in structural parameters (volume fraction, for example) between samples from different populations or subject to differing treatment regimes. Non-homogeneity of these parameters is virtually guaranteed, both between experimental animals and within the organ under consideration. A two-stage strategy is then desirable, the first stage involving unbiased estimation of the required parameter, separately for each experimental unit, the latter being defined as a subset of the organ for which homogeneity can reasonably be assumed. In the second stage, these point estimates are used as data inputs to a hierarchical analysis of variance, to distinguish treatment effects from variability between animals, for example. Techniques are therefore required for unbiased estimation of parameters from potentially small numbers of sample profiles. This paper derives unbiased estimates of linear properties in one special case—the sampling of spherical particles by transmission microscopy, when the section thickness is not negligible and the resulting circular profiles are subject to lower truncation. The derivation uses the general integral equation formulation of Nicholson (1970); the resulting formulae are simplified, algebraically, and their efficient computation discussed. Bias arising from variability in slice thickness is shown to be negligible in typical cases. The strategy is illustrated for data examining the effects, on the secondary lysosomes in the digestive cells, of exposure of the common mussel to hydrocarbons. Prolonged exposure, at 30 μg 1−1 total oil-derived hydrocarbons, is seen to increase the average volume of a lysosome, and the volume fraction that lysosomes occupy, but to reduce their number.
