Sending private messages over communication environments under surveillance is a very important challenge in communication security and has attracted a lot of attention from cryptographers through time. We believe that resources other than cryptographic keys can be used to provide communication privacy. We consider private message transmission (PMT) in an abstract multipath communication settin...

Solving algebraic problems is a complex process that is influenced by various factors including teachers‟ instruction. The present intense interest in research on teachers‟ knowledge and proficiencies demands that future problem-solving research pay close attention to the mathematical and pedagogical knowledge and proficiencies a teacher should possess. This study explores the Prospective Mathe...

The CEO of the University Research Foundation (URF), Dave Norton, decided to sponsor an information systems (IS) development project to facilitate automation of discovery disclosure tracking. Discovery disclosure is the process at URF that tracks establishment and progress of funded (federal grants and contracts) inventions, innovations, and discoveries made by principle investigators (PIs). Da...

The PMT gene family in Candida albicans encodes five isoforms of protein mannosyltransferases (Pmt proteins Pmt1p, Pmt2p, Pmt4p, Pmt5p, and Pmt6p) that initiate O mannosylation of secretory proteins. We compared virulence characteristics of pmt mutants in two complex, three-dimensional models of localized candidiasis, using reconstituted human epithelium (RHE) and engineered human oral mucosa (...

Putrescine N-methyltransferases (PMTs) are the first specific enzymes of the biosynthesis of nicotine and tropane alkaloids. PMTs transfer a methyl group onto the diamine putrescine from S-adenosyl-l-methionine (SAM) as coenzyme. PMT proteins have presumably evolved from spermidine synthases (SPDSs), which are ubiquitous enzymes of polyamine metabolism. SPDSs use decarboxylated SAM as coenzyme ...

The assumption for this research is that there are managers and members in distributed projects that do not have the right support and help from Project Management Tools (PMT), which would be useful in their work. The purpose of this paper is to improve the conditions for management tools in distributed projects. To achieve the purpose, an idealized PMT is designed, based on managerial cybernet...

This study evaluated the effects of problem-solving skills training (PSST) and parent management training (PMT) on children (N = 97, ages 7-13 years) referred for severe antisocial behavior. Children and families were assigned randomly to 1 of 3 conditions: PSST, PMT, or PSST and PMT combined. It was predicted that (a) each treatment would improve child functioning (reduce overall deviance and ...

Pasteurella multocida toxin (PMT) activates the G-proteins Gαi(₁₋₃), Gα(q), Gα₁₁, Gα₁₂ and Gα₁₃ by deamidation of specific glutamine residues. A number of these alpha subunits have signalling roles in neurones. Hence we studied the action of this toxin on rat superior cervical ganglion (SCG) neurones and NG108-15 neuronal cells. Both Gα(q) and Gα₁₁ could be identified in SCGs with immunocytoche...
