A taxonomic study of the genus Gautieria Vitt. is presented.
Existing type collections were re-examined, fully described and
figures. Twenty-six species are recognized. Two provisional subgenera
are proposed: Gautieria and Clelandia. Within the subgenus
Gautieria, two provisional sections are proposed: Gautieria and
Trappea. G. morchellaeformis var. globospora, and
G. morchellaeformis...
The design considerations for fast-settling operational
amplifiers (opamps) differ significantly between sampled-data switchedcapacitor
(SC) and conventional continuous-time applications. In SC
circuits, the shape of the output voltage waveform of an opamp is of no
consequence provided that the output settles to within a specified
tolerance of its steady-state value prior...
"An assessment of quota market efficiency: The New Zealand Annual Catch Entitlement (ACE) market
Balancing actual catch with Annual Catch Entitlement (ACE) is crucial to the efficient operation of the New Zealand Quota Management System (QMS). ACE market efficiency is dependent on the existence of ACE prices that reflect all...
The recent establishment of the Galápagos Marine Reserve (GMR) presents a unique opportunity to analyze the economic implications of using zonification as a tool to manage conflicting claims to a fragile and limited resource. Recognizing that the long-term success of the GMR depends on the cooperation of all of the...
The infrared absorption spectra in the out-of-plane
bending (v₂) region of potassium nitrate were studied for
three phases. Several types of sampled were used: nujol
mulls, fused samples, and N¹⁴-N¹⁵ isotopic mixtures. The
existence of three of the reported polymorphic phases was
confirmed by the spectra. The transitions between phase...
In recent years, studies dealing with temperature regulation,
temperature sensitivity, and physiological responses to temperature
in lizards and other reptiles have increased tremendously. It is
notable that snakes have been largely ignored in such studies. This
no doubt is due to their less direct relationship to ancestral endotherms.
However, problems...
Trace metals in the aquatic environment are generally concentrated
on the surface of solid geochemical phases which eventually become incorporated
into estuarine and marine sediments. The mechanism of trace
metal concentration is believed to be adsorption with various geochemical
phases such as hydrous metal oxides, clays, and organic matter.
Metals...

times of three, five, and ten hours. Parameters used for evaluation
of treatment were biochemical oxygen demand, chemical oxygen
demand, total organic...
Vertisols and other vertic-intergrade soils are found all over the globe, including many agricultural and urban areas. These soils are characterized by their cyclical shrinking and swelling behaviors, where bulk density and porosity distribution both vary as functions of time and/or soil moisture. In turn, alterations in physical soil parameters...
Selenium (Se) is an essential micronutrient of sheep. Supplementation is especially important in young lambs in order to prevent Se-deficiency signs. In the United States, the FDA regulates Se supplementation to ruminant diets at a level of 0.3 mg/kg Se (as fed basis). Questions still exist regarding what chemical form...
The 36 samples collected with a 22-foot semi-balloon shrimp
trawl at depths from 40 to 1,829 meters off the central coast of
Oregon between July 1961 and June 1962 provided preliminary data

Ireland's Catholic Church played an important role in the turn-of-the-century nationalism that shaped James Joyce's identity and writing; yet it also played an important part in preventing that nationalism from achieving its goals of autonomy and cultural independence. For Joyce, this was particularly evident in the dialects and
thought structures...
Pornography remains one of the most controversial topics in our culture. Politicians, religious groups, and special interest organizations tend to focus on the ‘effects’ pornography has on those who consume it, and fear that pornography is a threat to public health. The general discourse surrounding pornography is that men produce...

In the western United States, bighorn sheep (Ovis canadensis) have suffered major die-offs in every state since the mid-1800s, and disease from domestic sheep (Ovis aries) has been a primary factor in these events. Beginning in the early 1900s, poly-factorial, poly-microbial pneumonia was identified as a major disease affecting bighorn...
A survey for incidence and distribution of root diseases was conducted on the Kootenai National Forest using timber inventory subcompartments as primary sample units. Root diseases were located within 23 of 75 sampled subcompartments. At least 1.1 percent of the commercial forest lands within the Forest are infested with root...
An impact survey to determine extent and distribution of root disease centers was completed for the Nezperce National Forest, Idaho, in 1980. Lowlevel
color infrared photography was used to delineate root disease centers
within National Forest inventory subcompartments. Suspected root disease
centers were ground checked to determine associated fungi and...
Spectroscopic ellipsometry (SE) is used to characterize amorphous and crystalline thin films of TiO2. Amorphous precursor films of TiO2 are deposited by radio frequency magnetron sputtering on fused silica and silicon substrates. Annealing the amorphous precursor films induces them to crystallize into either pure or mixed phases of the three...
Methods used to establish permanent plots in precommercially thinned and unthinned stands to monitor root disease development are described. Plots were established in 22 Armillaria-infested stands in northern Idaho and western Montana. The proportion of trees dead and infected was significantly higher for planted than for natural regeneration at the...
Studies on hydromineral balance in fishes frequently employ measurements of electrolytes following euthanasia. We tested the effects of fresh- or salt-water euthanasia baths of tricaine mesylate (MS-222) on plasma magnesium (Mg²⁺) and sodium (Na⁺) ions, cortisol and osmolality in fish exposed to saltwater challenges, and the ion and steroid hormone...
In this study, we characterize the behavioral response of larval zebrafish (Danio rerio) to the noxious chemical allyl isothiocyanate (AITC), an agonist of the nociceptive TRPA1 ion channel, and utilize AITC as an aversive stimulus in an associative learning paradigm. We find that larvae exposed to AITC in both a...
