Abstract:

In a priori analogies, the analogue is constructed in imagination, sharing certain properties with the primary subject. The analogue has some further property clearly consequent on those shared properties. Ceteris paribus the primary subject has that property also. The warrant involves non-empirical, e.g., moral intuition but is also defeasible. The argument is thus neither deductive nor inductive, but an additional type. In an inductive analogy, the analogues back the warrant from below. Distinguishing these two types of arguments by analogy gives epistemic evaluative factors primacy over res

Abstract:

To be able to assess animal welfare the researcher must presuppose a number of background assumptions that cannot be tested by means of ordinary empirical data collection. In order to substantiate these assumptions two sorts of inferences have to be relied upon, which the authors designate by the terms 'analogies' and 'homologies'. Analogies are evaluative, philosophical reflections by means of which it is made clear what provisions or states constitute the welfare of humans and other animals. By means of analogies it may, for example be argued that animal welfare consists of subjective experi

Abstract:

Abstract This paper studies metaphor use in British Public Bill Committee debates. It focuses on the way in which legislators frame their arguments in metaphorical terms under the form of figurative analogies. Because these figurative analogies can be misleading by oversimplifying the issue under discussion, resisting them by putting forward counter-argumentation is a crucial and necessary skill. The purpose of this paper is to explore the phenomenon of countering figurative analogies in legislative debates, and to show that resistance to figurative analogies is a complex phenomenon comprising

Summary This paper examines the problem of differential identification as posed in Saussure’s Cours de linguistique générale. The solution proposed by Ducrot seems unlikely to have been Saussure’s own and would result in recognizing a proliferation of variants for every sign in the system. Saussure’s analogy with handwriting appears to provide a more promising line of approach, but in the end leads to no less intractable difficulties.

Abstract Diels-Alder and ene reactions of germaethene Me2Ge=C(SiMe3)2 (2) with butadienes respectively, take place regioselectively, as well as stereoselectively. They are accelerated by an increasing tendency of substituents in butadiene or propene to donate electrons (e.g. 2-methylbutadiene > butadiene; 2-methylpropene > propene), and retarded by an increasing bulkyness of substituents in 1,4- or 1,3-positions (e.g. 1-methylbutadiene > 2-methylbutadiene; 1-vinylpropene > propene).

In this communication we show that T cell locomotion is affected by direct interaction with neurohormones.

Activity was dependent on the peptide NH2-terminal sequence, stimulated by enkephalin analogues with specificity for classical delta or mu types of opiate receptor, and inhibited by the opiate receptor antagonist naloxone. Our studies suggest that such neuropeptides stimulate T cell chemotaxis by interaction with sites analogues to classical o

For these tools to be effective and not impact the design process in negative ways, they must fit well with the information and interaction needs of their users. However, the user requirements

Resolution of some of the potent GABA analogues, in particular (+)-(4S)- and (-)-(4R)-4- aminocyclopent-1-ene-1-carboxylic acid (5), has been achieved by crystallization of isopropylideneribonolactone esters or pantolactone esters of the phthalimido -protected intermediates.

Abstract:

3β,5,6β-Trihydroxy-5α-pregnan-20-one 3-pivalate (I) was converted into 3β,6β-dihydroxy-5-methyl-19-nor-5β-pregn-9-en-20-one 3-pivalate 5-acetate (II) under conditions of Westphalen rearrangement. Deoxygenation in the position 6β was effected by treatment of the corresponding 6β-thiobenzoate or thioimidazolide with tributyltin hydride. Progesterone analogues XII and XIII, prepared from the 6-deoxy compound IX, exhibit abortive activity.

Abstract:

Two new mechanical analogues for teaching a.c. power flow over a lossless line are suggested. The first analogue is simple. It illustrates the phase angle between the sending end voltage and the receiving end voltage. The second analogue is somewhat more complicated and mathematically exactly analogous to the a.c. power flow model. It uses a concept which is familiar to every human: the inertia of mass. With this analogue we illustrate not only the voltage phase shift but also the maximum power over a line.

In addition, new luciferin analogues providing longer wavelength luminescence have been developed that show promise for improved deep tissue imaging.

The aim of this study was to evaluate for the first time the in vivo brightness and spectral characteristics of firefly (Luc2), c

Their binding to staphylococcal cells is enhanced by the nongalloyl analogues (−)−epicatechin (EC) and (−)−epigallocatechin (EGC). EC and EGC significantly increased the capacity of ECg and EGCg to reduce levels of staphylococcal oxacillin resistance.

Synthetic unsaturated analogues of the natural polyamine were examined as possible substrates for spermine synthase and as replacements for spermidine in supporting the growth of SV-3T3 cells. It was found that N-(3-aminopropyl)-1,4-diamino-cis-but-2-ene [the cis isomer of the alkene analogue of spermidine] was a good substrate for spermine synthase, but that the trans isomer [N-(3-aminopropyl)-1,4-diamino-trans-but-2-ene] and the alkene analogue [N-(3-aminopropyl)-1,4-diaminobut-2-yne] were not substrates.

But until now, no information is available whether these treatment approaches might interfere with chemically related drugs, e.g. nucleoside analogues used in cancer or viral therapy.

Abstract:

Despite the many benefits of pulses, their consumption is still very low in many Western countries. One approach to solving this issue is to develop attractive pulse-based foods, e.g., plant-based cheeses. This study aimed to assess the suitability of different types of pulse flour, from boiled and roasted yellow peas and faba beans, to develop plant-based cheese analogues. Different stabilizer combinations (kappa- and iota-carrageenan, kappa-carrageenan, and xanthan gum) were tested. The results showed that firm and sliceable pulse-based cheese analogues could be prepared using all types of p
