The Hydraulic Laboratory of Liège University, Belgium, is historically considered from its foundation in 1937 to the mid-1960s. The technical facilities of the various Buildings are highlighted, along with canals and instrumentation available. It is noted that in its initial era, comparatively few basic research has been conducted, mainly due to the professional background of the professors leading the establishment. This state was improved in the past 50 years, however, particularly since the Laboratory was dislocated to its current position in the novel University Campus. Biographies of the leading persons associated with the Liège Hydraulic Laboratory are also presented, so that a comprehensive picture is given of one of the currently leading hydraulic Laboratories of Europe.

Allusions to other texts abound in John McGahern's fiction. His works repeatedly, though diffidently, refer to literary tradition. Yet the nature of such allusiveness is still unclear. This article focuses on how allusion in The Pornographer (1979) is depicted as an intellectual and social practice, embodying particular attitudes towards the function of texts and the knowledge they represent. Moreover, the critique of the practice of allusion that the novel undertakes is shown to have broader significance in terms of McGahern's whole oeuvre and its evolving attempts to salvage something of present value from the literature of the past.

Oral route is presently the gold standard in the pharmaceutical industry where it is regarded as the safest, most economical and most convenient method of drug delivery resulting in highest patient compliance. Over the past three decades, orally disintegrating tablets (FDTs) have gained considerable attention due to patient compliance. Usually, elderly people experience difficulty in swallowing the conventional dosage forms like tablets, capsules, solutions and suspensions because of tremors of extremities and dysphagia. In some cases such as motion sickness, sudden episodes of allergic attack or coughing, and an unavailability of water, swallowing conventional tablets may be difficult. One such problem can be solved in the novel drug delivery system by formulating “Fast dissolving tablets” (FDTs) which disintegrates or dissolves rapidly without water within few seconds in the mouth due to the action of superdisintegrant or maximizing pore structure in the formulation. The review describes the various formulation aspects, superdisintegrants employed and technologies developed for FDTs, along with various excipients, evaluation tests, marketed formulation and drugs used in this research area.

Background: Oleanolic Acid (OA) is a ubiquitous product of triterpenoid compounds. Due to its inexpensive availability, unique bioactivities, pharmacological effects and non-toxic properties, OA has attracted tremendous interest in the field of drug design and synthesis. Furthermore, many OA derivatives have been developed for ameliorating the poor water solubility and bioavailability. Objective: Over the past few decades, various modifications of the OA framework structure have led to the observation of enhancement in bioactivity. Herein, we focused on the synthesis and medicinal performance of OA derivatives modified on A-ring. Moreover, we clarified the relationship between structures and activities of OA derivatives with different functional groups in A-ring. The future application of OA in the field of drug design and development also was discussed and inferred. Conclusion: This review concluded the novel achievements that could add paramount information to the further study of OA-based drugs.

In this chapter, 18:1-2, 4-6 is identified as the original poem against Cush inherited by the supposed late-exilic redactor who added v 7 at the end of the poem. Verse 3 was originally a marginal note on 17:12-14 written in the post-exilic period which was mistakenly copied into the verse’s current position. The only intentional secondary addition made to the original oracle against Cush is v 7 where one finds some points of contact with chs 40-55. Verse 7 foretells that the Cushites who were stricken by YHWH in the past will one day acknowledge his sovereignty and bring tributary gifts to Zion. The future restoration of a once afflicted people, their journey to Zion, and various connections with chs 40-55 all suggest that 18:7 is a continuation of the same vision first set out in 14:1-2.

AbstractJohann Ludwig Wilhelm Thudicum described sphingolipids (SLs) in the late nineteenth century, but it was only in the past fifty years that SL research surged in importance and applicability. Currently, sphingolipids and their metabolism are hotly debated topics in various biochemical fields. Similar to other macromolecular reactions, SL metabolism has important implications in health and disease in most cells. A plethora of SL-related genetic ailments has been described. Defects in SL catabolism can cause the accumulation of SLs, leading to many types of lysosomal storage diseases (LSDs) collectively called sphingolipidoses. These diseases mainly impact the neuronal and immune systems, but other systems can be affected as well. This review aims to present a comprehensive, up-to-date picture of the rapidly growing field of sphingolipid LSDs, their etiology, pathology, and potential therapeutic strategies. We first describe LSDs biochemically and briefly discuss their catabolism, followed by general aspects of the major diseases such as Gaucher, Krabbe, Fabry, and Farber among others. We conclude with an overview of the available and potential future therapies for many of the diseases. We strive to present the most important and recent findings from basic research and clinical applications, and to provide a valuable source for understanding these disorders.

In recent years, The Confidence-Man: His Masquerade, a difficult work and for long an unjustly neglected one, has begun to command increasingly greater critical attention and esteem. As more than one contemporary writer has noted, the verdict of the late Richard Chase in 1949, that the novel represents Melville's “second best achievement,” has served to prompt many to undertake a second reading (or at least a first) of the book. Before this time, the novel had traditionally been the one Melville readers have shied away from—as overly discursive, too rambling altogether, on the one hand, or as an unfortunate outgrowth of the author's morbidity on the other. Elizabeth Foster, in the admirably comprehensive introduction to her valuable edition of The Confidence-Man (1954), systematically traces the history of the book's reputation and observes that even with the Melville renaissance of the twenties, the work stands as the last piece of the author's fiction to be redeemed. Only lately, she comments, has it ceased to be regarded as “the ugly duckling” of Melville's creations. But recognition does not imply agreement, and it should not be thought that in the past fifteen years critics have reached any sort of unanimity on the novel's content. Since Mr. Chase's study, which approached the puzzling work as a satire on the American spirit—or, more specifically, as an attack on the liberalism of the day—and which speculated upon the novel's controlling folk and mythic figures, other critics, by now ready to assume that the book repaid careful analysis, have read the work in a variety of ways. It has been treated, among other things, as a religious allegory, as a philosophic satire on optimism, and as a Shandian comedy. One critic has conveniently summarized the prevailing situation by remarking that “the literary, philosophical, and cultural materials in this book are fused in so enigmatic a fashion that its interpreters have differed as to what the book is really about.”

Over the past three or four years, great strides have been made in our understanding of the proteins involved in recombination and the mechanisms by which recombinant molecules are formed. This review summarizes our current understanding of the process by focusing on recent studies of proteins involved in the later steps of recombination in bacteria. In particular, biochemical investigation of the in vitro properties of the E. coli RuvA, RuvB and RuvC proteins have provided our first insight into the novel molecular mechanisms by which Holliday junctions are moved along DNA and then resolved by endonucleolytic cleavage.

AbstractMars simulation studies have in the past mainly investigated the effect of the simulation conditions such as UV radiation, low pressure and temperature on pure cultures and much has been learnt about the survival potential of sporeformers such asBacillus subtilis. However, this approach has limitations as the studies only investigate the properties of a very limited number of microorganisms. In this paper we propose that Mars simulations should be carried out with complex microbial communities of Martian analogues such as permafrost or the deep biosphere. We also propose that samples from these environments should be studied by a number of complementary methods and claim that these methods in combination can provide a comprehensive picture of how imposed Martian conditions affect the microbial community and in particular the survival of its constituents – microbes as well as biological material in general. As an interesting consequence this approach can lead to the isolation of bacteria, which are more recalcitrant to the imposed Martian conditions than the pure cultures that have previously been studied.
