Hands-off legislation, toothless policy statements, unknowing parents, uncaring participants, and unwilling social network intermediaries (SNIs), have conspired to invite impersonation, denigration, sexual or aggressive solicitation, cyber-bullying, and happy slapping to the members of most social networking websites (SNWs). The situation is serious serious because the user-generated content (U...

If C is a clutter with n vertices and q edges whose clutter matrix has column vectorsA = {v1, . . . , vq}, we call C an Ehrhart clutter if {(v1, 1), . . . , (vq, 1)} ⊂ {0, 1} n+1 is a Hilbert basis. Letting A(P ) be the Ehrhart ring of P = conv(A), we are able to show that if C is a uniform unmixed MFMC clutter, then C is an Ehrhart clutter and in this case we provide sharp upper bounds on the ...

The term “alkylating agent― has been defined and a detailed discussion made of the mechanisms (Sni and Sn@) by which they interact with nucleophilic centers. The various nucleophiles likely to be encountered in vivo are discussed in terms of their relative reactivities toward alkylating agents. With regard to Sn@ reactors it was possible to group them into four sections on the basis of thei...

Fig mosaic disease (FMD) is a viral disease that spreads in all Tunisian fig (Ficus carica L.) orchards. RT-PCR technique was applied to leaf samples of 29 fig accessions of 15 fig varieties from the fig germplasm collection of High Agronomic Institute (I.S.A) of Chatt-Mariem, to detect viruses associated to FMD. Analysis results show that 65.5% of the accessions (19/29) and 80.0% (12/15) of th...

Often in biomedical studies, the routine use of linear mixed-effects models (based on Gaussian assumptions) can be questionable when the longitudinal responses are skewed in nature. Skew-normal/elliptical models are widely used in those situations. Often, those skewed responses might also be subjected to some upper and lower quantification limits (QLs; viz., longitudinal viral-load measures in ...
