A facile spectrophotometric method is proposed for determination of Colchicoside (COLSID) in bulk and in dosage forms using ceric ammonium sulphate (CAS). Method involves addition of a known excess of CAS to COLSID and determination of residual CAS with a fixed amount of either Azure B (AB), measuring absorbance at 633nm or Safranin O (SO), measuring absorbance at 519 nm. Calibration graphs are...

We show that a wide variety of non linear cellular automata can be written as a semidirect product of linear ones and that these CAs can be predicted in parallel time O log t This class includes any CA whose rule when written as an algebra is a solvable group We also show with an induction on levels of commutators that CAs based on nilpotent groups can be predicted in parallel time O log t

Neste artigo propõem-se duas metodologias de análise por injeção seqüencial para a determinação de alumínio reativo em águas, baseadas na reação entre o “chrome azurol S” (CAS) e o alumínio. Os métodos desenvolvidos incluem uma determinação direta e uma metodologia cinética (para aplicação a águas residuais com coloração), implementadas na mesma montagem. Os intervalos dinâmicos de trabalho são...

Over the past decade, a pair of instructions called load-linked (LL) and store-conditional (SC) have emerged as themost suitable synchronization instructions for the design of lock-free algorithms. However, current architectures donot support these instructions; instead, they support either CAS (e.g., UltraSPARC, Itanium) or restricted versions ofLL/SC (e.g., POWER4, MIPS, Alpha). T...

The high-pathogenicity island (HPI) of yersiniae encodes an iron uptake system represented by its siderophore yersiniabactin (Ybt). The HPI is present in yersiniae with high levels of pathogenicity--i.e., Yersinia pestis, Y. pseudotuberculosis, and Y. enterocolitica biogroup (BG) 1B--but absent in Y. enterocolitica strains with low (BG 2 to 5) and no (BG 1A) levels of pathogenicity and has been...

— We shall consider an elastic body, with a surface which is partially stuck to a fixed plane. The stuck région has a diameter e and the distance between two neighbouring zones is r\. The critica! size of these zones is given by the relation e = O On). In this case the limit behaviour of the body is described by a boundary condition which is intermediate between the perfect stuck and unstuck ca...

The health impact on populations residing in industrially contaminated sites (CSs) is recognized as a public health concern especially in relation to more vulnerable population subgroups. The aim of this study was to estimate the risk of congenital anomalies (CAs) in Italian CSs. Thirteen CSs covered by regional CA registries were investigated in an ecological study. The observed/expected ratio...

RÉSUMÉ. La qualité de service (QoS) des services Web est un facteur clef de leur réussite. Ceci nécessite le développement de nouvelles méthodes afin de l’analyser. Nous proposons ici des familles de modèles majorant le temps de réponse des services Web composites pour deux types de composition : le « fork and merge » statique et aléatoire. Pour le premier cas, la complexité de résolution des m...

This study examined the welfare implications of euthanizing broilers with 3 gas mixtures relevant to the commercial application of controlled atmosphere stunning (CAS). Birds were implanted/equipped with electrodes to measure brain activity (electroencephalogram, EEG) and heart rate. These signals were recorded using a purpose-built telemetry-logging system, small enough to be worn by each bird...
