Age, growth, and long-distance dispersal in the western North Atlantic of vexillifer larvae of the pearlfish, Echiodon dawsoni, with notes on Carapus bermudensis (Ophidiiformes: Carapidae)

Creator:: Govoni, John J., Terwilliger, Mark, and Markle, Douglas F.
Abstract:: We examined 120 vexillifer larvae of Echiodon dawsoni and 40 of Carapus bermudensis collected from the continental shelf and slope of the Gulf of Mexico and the western North Atlantic to Nova Scotia. Age was estimated for a subset of vexillifers, from which otoliths (sagittae) were excised and growth increments...

The extraction of pentachlorophenol from pressure treated wood using supercritical carbon dioxide

Creator:: Yi, Jung-Seok
Abstract:: The extraction of pentachlorophenol (PCP) from pressure treated wood wafers with supercritical carbon dioxide has been studied. Experimental data were obtained for the effects of pressure (17.5 - 25.0 MPa), temperature (313 - 353 K), flow rate (1 - 3 ml/min at supercritical conditions), and sample size (0.8 x 10...

Geostatistical applications to salinity mapping and simulated reclamation

Creator:: Al-Taher, Mohamad A.
Abstract:: Geostatistical methods were used to find efficient and accurate means for salinity assessment using regionalized random variables and limited sampling. The random variables selected, sodium absorption ratio (SAR), electrical conductivity (EC), and clay content were measured on samples taken over an area of fifteen square miles. Ordinary kriging and co-kriging...

Development of a test procedure for water sensitivity of asphalt concrete mixtures

Creator:: Al-Swailmi, Saleh H.
Abstract:: Environmental factors such as temperature, air, and water can have a profound effect on the durability of asphalt concrete mixtures. In mild climates where good quality aggregates and asphalt cement are available, the major contribution to deterioration may be due to traffic loading and the resultant distress is manifested in...

Cyclic nucleotides, cyclic nucleotide phosphodiesterase, protein kinase, and phosphoprotein phosphatase in the central nervous system of Manduca sexta

Creator:: Albin, Edward Elmo
Abstract:: Adenosine 3', 5' -cyclic monophosphate (cyclic AMP, cAMP) and guanosine 3', 5' -cyclic monophosphate (cyclic GMP, cGMP) were quantitated in the central nervous system (CNS) of the insect Manduca sexta by competitive protein binding techniques. The M. sexta CNS was found to contain a strikingly high level of cGMP, about...

S-adenosylmethionine : [triangle]²⁴-sterol methyltransferase and the regulation of ergosterol biosynthesis in Saccharomyces cerevisiae

Creator:: Bailey, Richard B.
Abstract:: The inhibition of S-aden.osylmethionine: Δ²⁴-sterol methyltransferase (EC 2.1.1.41) activity by endogenous cellular components has been studied in vitro. The principal inhibitors were Na⁺ and K⁺; Cs⁺, NH₄⁺ and Li⁺ were also shown to inhibit the reaction. The inhibition by potassium cation has been studied, and we have found that energy...

Cholinesterase activity in the neural retina of the developing chick

Creator:: Rynd, Lori Suzanne
Abstract:: Developmental changes in the enzymes acetylcholinesterase (EC 3.1.1.7) and pseudocholinesterase (EC 3.1.1.8) were examined in ovo and in vitro in the neural retina of the developing chick. In addition, investigations of cellular interactions and hormones as possible control mechanisms of enzyme synthesis were made. The specific activity of acetylcholinesterase, a...

Multiple forms of carboxylesterases in the green bean (Phaseolus vulgaris L.) and pea (Pisum sativum L.)

Creator:: Veerabhadrappa, Patnagere Siddaveera Sheety
Abstract:: Esterase activity of an aqueous extract of the green bean was separated into fourteen bands, while aqueous extracted pea esterases revealed seven bands, by polyacrylamide-gel electrophoresis. The fourteen bands of bean esterase activity formed three groups; slow, intermediate and fast moving. α-Naphthyl acetate, propionate, and n-butyrate and AS naphthol acetate...
