When monitoring a process which has multivariate normal variables, the Shewhart-type control chart (Hotelling (1947)) traditionally used for monitoring the process mean vector is effective for detecting large shifts, but for detecting small shifts it is more effective to use the multivariate exponentially weighted moving average (MEWMA) control chart proposed by Lowry et al. (1992). It has been...

We describe the larval stage of Simulium cuasiexiguum Shelley, Luna Dias, Maia-Herzog & Lowry and Simulium obesum Vulcano and provide new distribution records of four black fly species in the State of São Paulo (Simulium cuasiexiguum, Simulium metallicum s.l. Bellardi, Simulium stellatum Gil Azevedo, Figuer6 & Maia-Herzog and Simulium oyapockense s.l. Floch & Abonnenc) and three species in the ...

Typically, these kinds of questions are answered with reference to the inherent properties of the assessment mechanism. For example, Lowry et.al. [7] and Menzies & Cukic [8] contrast the costs and defect detection decay rates of formal methods, white box testing, and black box testing. That analysis made assumptions about the completeness of the search and the cost of setting up each run. A dra...

Meryta pastoralis F. Tronchet & Lowry, a new species from the island of Hiva Oa in the Marquesas archipelago, is described and illustrated. It differs from other Polynesian members of the genus by its fully free ovaries, a feature shared with one other species found in the region, Meryta choristantha (native to the Austral Islands), distinguished by its ovate to spatulate (vs. elliptic to obova...

inhibiting subtilisin BPN'. This paper describes purification and characterization of a subtilisin inhibitor (FMSI) from foxtail millet grain. Protein was measured by the method of Lowry et al.2) using bovine serum albumin as a standard. Protein concentrations of enzyme solutions were measured spectrophotometrically with extinction coefficients as described previously.3) The concentration of St...

Note. Since this paper was accepted for publication, crystalline porphobilinogen has been prepared from human acute porphyria urine (Westall, R. G. (1952), Nature, Lond., 170, 614). The results described in the present paper have been confirmed in every respect using crystalline material we have prepared by Westall's method, from the urine of rabbits in which porphyria had been induced by the a...

About the Cover: Nanomaterials are highly reactive and dynamic in the environment and can undergo a range of physical, chemical, and biological transformations. Some examples of transformations include heteroaggregation, adsorption of biomacromolecules, biodegradation, and sulfidation. These transformations will affect the nanomaterial properties and environmental behaviors and impacts. Profess...
