Delineation of female performance on the Rey-Osterrieth Complex Figure.

103 female college students (aged 18–24 yrs) were administered the Rey-Osterrieth Complex Figure on Copy, Immediate Recall, and 20-min Delayed Recall. Ss were grouped based on handedness, familial handedness, and academic major (mathematics/science and nonmath/science). Based on the scoring system of D. Waber and J. Holmes (see PA, Vols 72:24305 and 74:9917) the mathematics/science anomalous dominance groups obtained higher mean scores than all other subgroups, and the non-math/science familial right-handers were the low performers. The high-performing groups may have an increased ability to coordinate the use of left- and right-hemisphere processing. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Watershed and River Systems Management Program: Overview of Capabilities

Beginning in January 1992, the Bureau of Reclamation (Reclamation) and the US Geological Survey (USGS) formulated plans for the Watershed and River Systems Management Program—a cooperative interagency effort to develop and implement flexible and robust river basin management tools for the benefit of managers and decision makers using a data centered approach. In addition to Reclamation and the USGS, a number of other agencies and universities have made substantial contributions to the success of the program. The result has been the need driven research and development of state-of-the-art technology which benefits water managers and technical specialists in many river basins.     

An empirical study of domain knowledge and its benefits tosubstructure discovery

Discovering repetitive, interesting, and functional substructures in a structural database improves the ability to interpret and compress the data. However, scientists working with a database in their area of expertise often search for predetermined types of structures or for structures exhibiting characteristics specific to the domain. The paper presents a method for guiding the discovery process with domain specific knowledge. The SUBDUE discovery system is used to evaluate the benefits of using domain knowledge to guide the discovery process. Domain knowledge is incorporated into SUBDUE following a single general methodology to guide the discovery process. Results show that domain specific knowledge improves the search for substructures that are useful to the domain and leads to greater compression of the data. To illustrate these benefits, examples and experiments from the computer programming, computer aided design circuit, and artificially generated domains are presented     

Fourier-transform Raman spectra of ivory. III: Identification of mammalian specimens

The FT-Raman spectra of six mammalian ivories, other than elephant and mammoth, are presented and spectral differences formulated into a protocol for the identification of animal species from the ivory samples. In this study, sperm whale, walrus, wart hog, narwhal, hippopotamus and domestic pig are considered. The results, which are obtained non-destructively from a variety of specimens, suggest that FT-Raman spectroscopy provides a potentially useful method for the identification of mammalian ivory.     

Antimicrobial mixtures used by tissue banks for harvested skin: comparative in vitro activity

The activities of antimicrobial combinations from three geographically diverse skin/tissue banks used in the processing of skin/ tissue were compared using bacteria and yeast isolated from burn patients. All formulations showed 90% or more effectiveness against bacteria generally susceptible to antibiotics but were less effective (60-80%) when tested against bacteria resistant to specific antimicrobials. Anti-yeast activity was present when an appropriate antifungal agent was included in the combination. All formulations were stable for at least six weeks. Results of this study raise certain questions about the use of these antimicrobial combinations in contemporary skin/tissue banking and point the way toward areas for future study.     

Peanut proteins as food supplements: A compositional study of selected Virginia and Spanish peanuts

Three peanut cultivars (Virginia, red-skinned, and white-skinned Spanish) were analyzed and compared as potential protein supplements for food uses. The seeds were solvent-extracted in the laboratory to yield defatted flours with 9–10% nitrogen contents. Protein isolates were prepared from the flours by subsequent extraction with dilute salt solutions buffered at pH 7.0. Various parameters were compared, such as total protein contents, soluble proteins, amino acid compositions of flours and protein isolates, free amino acids and free sugars of defatted flours, and certain trace minerals in flours and soluble proteins. The application of these results to the selection of certain types of peanuts for potential uses as protein supplements in food products is discussed. Presented in the Symposium, Oilseed Proteins, 66th Annual AOCS Meeting, Dallas, Texas, April 27–30, 1975.     

Immunization of Aotus nancymai with recombinant C terminus of Plasmodium falciparum merozoite surface protein 1 in liposomes and alum adjuvant does not induce protection against a challenge infection

Merozoite surface protein 1 (MSP-1) of Plasmodium falciparum is an antimalarial vaccine candidate. The highly conserved 19-kDa C-terminal processing fragment of MSP-1 (MSP-1(19)) is of particular interest since it contains epitopes recognized by monoclonal antibodies which inhibit the invasion of erythrocytes in vitro. The presence of naturally acquired anti-MSP-1(19) antibodies in individuals exposed to malaria has been correlated with reduced morbidity, and immunization with an equivalent recombinant P. yoelii antigen induces substantial protection against this parasite in mice. We have expressed P. falciparum MSP-1(19) in Escherichia coli as a correctly folded protein and immunized Aotus nancymai monkeys by using the protein incorporated into liposomes and adsorbed to alum. After vaccination, the sera from these animals contained anti-MSP-1(19) antibodies, some of which competed for binding to MSP-1(19) with monoclonal antibodies that inhibit parasite invasion of erythrocytes in vitro. However, after challenge with either a homologous or a heterologous strain of parasite, all animals became parasitemic and required treatment. The immunization did not induce protection in this animal model.     

Taste-potentiated noise-illness associations.

In five experiments we attempted to establish aversions to a noise presented each time thirsty rats licked a water source. Using an apparatus and a procedure similar to those of previous studies which reported noise-illness associations, weak taste-potentiated noise-illness associations were found (Experiment 1). However, when the apparatus and procedure were varied, noise-illness associations were not observed (Experiments 3, 4, and 5). The noise used in all of these failures was readily associated with shock (Experiment 2), which indicates that this noise was salient to the rats and could be associated with an aversive event. These failures to find noise-illness associations occurred despite the fact that the conditions were chosen to maximize the likelihood of observing these associations. Taste-illness associations always developed normally. The results are consistent with the idea that conditioned aversions to all exteroceptive stimuli are not equally well potentiated by taste.
