Carl Remigius Fresenius: Analytical Chemistry´s Father
No full textEn este trabajo se pasa revista a los aspectos de la vida y de la obra de Carl Remigius Fresenius, un eminente químico alemán del siglo XIX considerado como el padre de la Química Analítica. El trabajo se divide en varias secciones y hace hincapié: i) en la publicación de sus dos libros de texto sobre análisis cualitativo (1841) y cuantitativo (1845), que se convirtieron en un referente durante casi un siglo, en la sistemática de cationes conocida como marcha del sulfhídrico; ii) en la fundación de un laboratorio en Wiesbaden (1848) destinado a la enseñanza de la química y a sus aplicaciones practicas, y; iii) en la fundación de la primera revista analítica, el “Zeitschrift für analytischen Chemie” (1861). Fresenius es considerado por la Federación Europea de Sociedades Químicas como uno de los cien químicos más eminentes de la historia.This paper reviews aspects of the life and work of Carl Remigius Fresenius, an eminent German chemist of the nineteenth century considered as the father of analytical chemistry. The manuscript is divided into several sections and emphasizes the publication of two textbooks on qualitative (1841) and quantitative (1845) analysis, which became a landmark for nearly a century, paying also attention to the systematic cation analysis known as “hydrogen sulphide scheme”, to the foundation of a laboratory in Wiesbaden (1848) for the teaching of chemistry and its practical applications, and in the founding of the first analytical journal, "Zeitschrift für analytische Chemie" (1862). Fresenius is considered by the Federation of European Chemical Societies as one of the hundred most distinguished chemists of the history
Privacy protection against physical intrusion: development of a pure intrusion tort in England and Wales
No full textThis article argues that intrusion into privacy is not comprehensively protected in England and Wales despite the availability of the cause of action for misuse of private information. Therefore, the author argues for the development of pure intrusion tort category in England and Wales
The dynamics and genius of Nigeria's indigenous legal order
No full textThis article challenges the colonial delegitimization of Nigeria's customary law. The author describes customary law's fundamental bases, and argues that these bases are what ensured customary law's survival during colonial rule, and also what provide for customary law's contemporary relevance. Globalization, increased international interaction, and the eclipse of tribal insularity necessitate a permanent form of customary law that is decipherable to foreigners and non-Indigenous people of Nigeria. However, the author opines that if rigidification of customary law is to be avoided, then the present practice of proving it as a fact ought to be retained. Factual proof is defended as an incident of the primordial nature and primary source of customary law, rather than any weakness in the comparison of customary law with the received English law. Under Nigerian law, after a rule of customary law is proved to exist, the court must consider whether it is judicially enforceable, or whether it is repugnant to natural justice, equity and good conscience. The author argues that the 'repugnancy doctrine' was routinely employed in a legal 'cleansing' mission, and was the engine for the imposition of hegemonic, foreign culture. The author suggests caution in the uncritical and contemporary use of the repugnancy doctrine and its precedents. Other instances of non-judicial enforcement of customary law are also considered, such as the contractual exclusion of customary law, and the exclusion of customary law based on the uncustomary nature of the subject matter of litigation. Finally, the author addresses the specific question of the constitutionality of customary law. Customary law's patriarchal foundation and general discrimination against women and female children are problematic issues that require sensitive and imaginative judicial use of customary law. The author argues that the Nigerian judiciary should undertake careful constitutional and sociological analysis before striking down any rule of customary law. The court should make reference to South Africa's constitutional experience, which has comparative similarities to Nigeria. The article concludes with a call for an interpretive approach to customary law that ensures its survival and adaptation to the dictates of equality in an egalitarian society

Body parts in property theory: an integrated framework
No full textThe role of property theory as a framework for analysis and regulation of body parts has become a debate of topical importance because of the emergence of biomedical technologies that utilise body parts, and also because the application of the concept of property, even with respect to historically and traditionally accepted forms of property, raises serious challenges to the property analyst. However, there is another reason for the topicality of property in relation to body parts: a proprietary approach confers on a claimant the advantage of continuing control that is tellingly lacking in non-property frameworks underpinned, for instance, by consent, negligence, privacy and unjust enrichment rules. In some circumstances, such as an unauthorised blood test performed on a blood sample obtained with consent, the continuing control provided by property law might be the only chance a claimant has to obtain a remedy. Economy of space, however, requires that only a prolegomenon on body parts and property theory is given below. Thus, the analysis begins by providing in outline a framework for comprehensive analysis of body parts within the realm of property theory; thereafter, the author engages with the normative question of whether body parts or rights exercisable over body parts could be admitted into the category of property

‘Orphaned’ transplantable organs: Law, ethics, and ownership
No full textThe legal status of an organ, in the period between its extraction from the body of a donor and its implantation in the body of a recipient, is unclear. In that period, the excised organ might be said to be orphaned because of its ambiguous custodial and proprietary status, and a host of activities might take place which could jeopardise its safety or viability for transplantation. For instance, what happens if the organ was lost or damaged in transit? Not inconceivably, a thief might snatch the organ from the possession of the transplant team; a transplant surgeon could use the organ for the treatment of their relative or close friend, a celebrity, or an influential political figure, instead of transplanting the organ into the properly selected and designated recipient contrary to the established allocation criteria. The excised organ might be damaged maliciously by a third party, say, an enemy of the proposed recipient who was bent on frustrating the recipient’s only means of receiving a life-saving treatment. Further, a live donor might change their mind on donation to the potential recipient after the organ has already been extracted. While these scenarios raise an interesting mix of legal, ethical, political and social questions, a fundamental enquiry that permeates the whole gamut of issues engendered by the hypothetical above is the question of ownership and proprietary entitlement to an excised (orphaned) organ. Accordingly, this article interrogates the question of proprietary control or ownership of an orphaned organ.Peer reviewe

Automatedgeneration of fuzzy control system using genetic algorithm, 1995
No full textFuzzy logic based controllers have emerged to be an inexpensive and simple solution for complex control problems. The main components of the fuzzy logic control are the rule base, the membership functions, and the inference engine. Membership functions are used to combine the antecedents and consequent (of the rules) to determine the output of the rules. Fuzzy controllers, however, suffer from significant drawbacks such as the formulation of the membership functions and tuning the rule base. In this thesis, a genetic algorithm is used to generate the fuzzy logic controller's rule base and to tune the membership functions. Temperature and pressure control in a boiler plant is used as a test bed application
