This paper reports on photocatalytic decolorization of a hazardous indigo carmine dye solution. The photocatalytic decolorization was carried out in the presence of the catalyst ZnO. The effect of catalyst dose, pH and initial dye concentration on the degradation process has been assessed. The aqueous dye solution was degraded in a photochemical reactor in the presence of UV light (365nm) along...

Because the parturient should be always considered as a patient with a full stomach and a possible difficult airway, succinylcholine is considered the muscle relaxant of choice for rapid sequence induction of general anesthesia. During pregnancy, the level of plasma cholinesterase which hydrolyses succinylcholine is moderately decreased, and hence hydrolysis of succinylcholine remains within th...

In this paper we present eFarnel, a new electronic voting scheme based on the paper-based Farnel protocol. The new scheme corrects problems observed in previous proposes to simulate Farnel electronically. Moreover, we also define a new kind of mix net, called F-Mix-Net, which is required by our protocol.

A MIX net takes a list of ciphertexts (c1; ; cN) and outputs a permuted list of the plaintexts (m1; ; mN) without revealing the relationship between (c1; ; cN) and (m1; ; mN). This paper shows that the Jakobsson's ash MIX of PODC'99, which was believed to be the most eecient robust MIX net, is broken. The rst MIX server can prevent computing the correct output with probability 1 in our attack. ...

Lactose is typically produced via cooling crystallization either from whey(-permeate) (edible-grade) or aqueous solution (pharmaceutical-grade). While in solution, lactose present 2 anomeric forms, α- and β-lactose. During under standard process conditions, only α-lactose crystallizes, depleting the of α-anomer. In practice, mutarotation kinetics are often assumed to be much faster than crystal...

Despite the considerable variation in milk composition found among mammals, a constituent common across all groups is lactose, the main sugar and osmole in most eutherians milk. Exceptions to this are the families Otariidae (fur seals and sea lions) and Odobenidae (walruses), where lactose has not been detected. We investigated the molecular basis for this by cloning alpha-lactalbumin, the modi...

Lactose intolerance has been reviewed in published statements by the Protein Advisory Group of the United Nations System,’ the Food and Nutrition Board of the National Research Council,2 and the American Academy of Pediatrics, Committee on Nutrition.’ Each of these statements deals principally with the advisability of encouraging population groups with a high rate of lactose intolerance to cons...

Mutations in the lacY gene of Escherichia coli have been used to analyze the functional organization of lactose permease. Deletions suggest that the NH2 terminus of lactose permease is not essential and can be replaced by residues of the cytoplasmic enzyme beta-galactosidase. Negative dominant mutations in the lacY gene can be explained by the assumption that membrane-associated lactose permeas...
