abstract sensitive and precise voltammetric methods for the determination of trace amounts of furaldehydes, mainly as furfural (f) and 5-hydroxymethyl-2-furaldehyde (hmf), in waste waters and other matrices is described. determination of total furaldehyde at < ?g g-1 levels in alkaline buffered aqueous media was individually investigated. by the use of ordinary swv and adsorptive square wave ...
introduction acetic acid bacteria are large group of obligate aerobic gram negative bacteria with the ability to oxidize ethanol to acetic acid (1). they are widely distributed in natural habitats and classified in family acetobacteraceae. members of this family are useful in industrial production of vinegar(2). acetic acid bacteria (aab) can use substrates as glucose, ethanol, lactate or glyc...
The term ‘fragmentation functions’ is widely used for two related if conceptually different sets of functions describing final-state single particle energy distributions in hard scattering processes (see Refs. [1,2] for introductory reviews, and Refs. [3,4] for summaries of recent experimental and theoretical research in this field). The first are cross-section observables such as the functions...
The story of Abraham’s willingness to give up his beloved son (Gen. 22) is a highly productive text – that is, it has triggered subsequent literary activity and played significant role in the composition shaping other texts. In this essay, I want first explore possibility 1 Kgs 17–18 yet another which an author alluded Gen. 22 then reflect on use as source for narratives composed analogies it.

Platelet concentrates for surgical use are autogenous regenerative preparations, produced by the centrifugation of the patient own blood sample. Most techniques are often regrouped inappropriately under the historical term of Platelet-Rich Plasma (PRP). Since 15 years, their use dramatically increased in many surgical fields, particularly in oral and maxillofacial surgery. The literature on thi...
In previous lectures we’ve mentioned that one of the reasons that distributed systems are different (and more complicated) than nondistributed systems is due to partial failure of system components. We’ve mentioned that dependability is an important challenge in designing and building distributed systems and that the presence of failure often makes achieving transparency (e.g., for RPC) difficu...
Evidence based medicine Evidence-based medicine relies mainly on the findings from clinical trials, and to minimise selection bias such trials should ideally be randomised. As the results of clinical studies are rarely identical, the fairest judgement on the effectiveness of a therapeutic intervention is generated through systematic review of clinical trials. Systematic reviews have to demonstr...
