Cathepsin D occurs in two forms, a single polypeptide chain (Mr 44 000) and a non-covalent complex of two peptides of Mr 14 000 and 30 000 that is derived by proteolytic processing of the 44 000 polypeptide. The two forms from bovine spleen are closely similar in secondary structure content, in aromatic amino acid environment and in the two step denaturation behaviour. Enzyme activity is lost i...

Deduction chains represent a syntactic and in a certain sense constructive method for proving completeness of a formal system S with respect to the class of S-structures. Given a formula A, the deduction chains of A are built up by systematically decomposing A into its subformulae. In the case where A is a valid formula, the decomposition yields a (usually cut-free) proof of A in the system S. ...

Laying out the logic of Bourdieu’s approach to institutional fi elds, this essay argues that Bourdieu’s theorization of the logic of practice is a generic contest for domination in a plurality of homologously organized fi elds. Bourdieu aligns all practices through the logic of domination, which allows him to homologize group relations in every fi eld. This homologization depends on a homogeniz...

Management research has begun to explore how cultural entrepreneurs use established or declining societal traditions create distinctive new ventures and products. In this study, we propose an alternative pathway for creating entrepreneurial opportunities, that is, through leveraging extinct traditions. Extinct yield opportunities highly products ventures, yet their entails substantial challenge...

This paper contains some valid interpretations of the surgical explanations of the disease Cancer in terms of such relative diseases in Ayurveda. This is a result of a critical observation of the Susruta Samhita, followed by the translation of this authentic text of ancient Indian Surgery done by the author and his colleagues.

There is increasing pressure, both from institutions central to the national scientific mission and from regional and national accrediting agencies, on natural sciences faculty to move beyond course examinations as measures of student performance and to instead develop and use reliable and valid authentic assessment measures for both individual courses and for degree-granting programs. We repor...

Some gastropod specimens belonging to the planorbid genus Ferrissia were recently collected in Lebanon and in Iraq, where the autochthonous species Ferrissia clessiniana (Jickeli, 1882) is supposed to occur. The molecular identification of collected specimens proved that they belong to the allochthonous species Ferrissia fragilis (Tryon, 1863), the protagonist of a dramatic cryptic invasion whi...

A simple method for isolation of kallikrein from human plasma is described. Before activation of the enzyme with acetone, the plasma was treated with 0.2 M-methylamine at pH 8.2 to inactivate a2-macroglobulin and thus prevent the irreversible binding of the active enzyme to the inhibitor. The enzyme was adsorbed on soya-bean trypsin inhibitor-Sepharose 4B and eluted with 5 mM-NaOH, pH 11.3. It ...

Crossover and mutation operations are speci c to this problem One or two point crossover of chains is not directly applicable because the o spring would not always consist in valid chains for the language The same thing can be said about mutation Both cases are solved by codifying the chains with their parse trees or as we will do here by means of their syntax trees annotated with the names of ...
