Research On Phenol Wastewater Treatment By Electrochemical Oxidation, Tian-Cheng Li, Shen-Lin Zhu
Research On Phenol Wastewater Treatment By Electrochemical Oxidation, Tian-Cheng Li, Shen-Lin Zhu
Journal of Electrochemistry
Electrochemical oxidation is an effective technology for the phenol wastewater treatment, and the anode properties are important to the electrochemical oxidationefficiency. The over-potentials of oxygen evolution have been measured for thestainless steel, feasible graphite and SnO_2/Ti anode respectively. Moreover, the synthetic phenol wastewater was treated by the electrochemical oxidation with the stainless steel or feasible graphite anodes. The experimental results showed that the order of the over-potential is SnO_2/Ti > graphite > stainless steel; meanwhile, the COD values of purified water were approaching to or less than 100 mg·L~(-1), and the phenol concentrations in the purified water were below 0.5 mg·L~(-1).

Cervids readily adapt to suitable human-altered landscapes and can cause several types of damage, including economic loss associated with landscape and agricultural plantings, human health and safety concerns, and adverse impacts on natural habitats. The need for effective, practical, and nonlethal tools to manage damage caused by elk (Cervus elaphus), mule deer (Odocoileus hemionus), and white-tailed deer (Odocoileus virginianus) has been heightened by the growing prevalence of locally overabundant populations and public demand for nonlethal wildlife management methods. Various frightening devices are available commercially, but most have not been subjectively evaluated. We used consumption …

United States Department of Agriculture Wildlife Services: Staff Publications
The need for alternative predator capture techniques is increasing because of concerns about the efficiency, selectivity, and injury of currently available capture methods. There also is a need for comparative data evaluating new or seldom used methods. In an initial evaluation, we first surveyed wildlife managers for information on cage-trapping; using these data, we conducted a field study of 4 coyote (Canis latrans) capture systems for animal damage management. We tested the SoftCatch®, Collarum®, Wildlife Services–Turman, and Tomahawk®, systems for capturing coyotes in Arizona and south Texas during 2001 and 2002. We determined capture efficiency and selectivity and …

The increased use of radio-telemetry for studying movement, resource selection, and population demographics in reptiles necessitates closer examination of the assumption that radiotransmitter attachment does not bias study results. We determined the effects of radiotransmitter attachment on fecal glucocorticoid metabolite levels of wild three-toed box turtles (Terrapene carolina triunguis) in captivity. During May 2002 we captured 11 adult three-toed box turtles in central Missouri. We housed turtles in individual pens in a semi-natural outdoor setting. We radio-tagged 6 turtles, and the remaining 5 turtles served as controls. We captured and handled all turtles similarly during treatments. We collected …
Food Habits Of Wolves In Relation To Livestock Depredations In Northwestern Minnesota, Andreas S. Chavez, Eric M. Gese
Food Habits Of Wolves In Relation To Livestock Depredations In Northwestern Minnesota, Andreas S. Chavez, Eric M. Gese
United States Department of Agriculture Wildlife Services: Staff Publications
Wolves (Canis lupus) have recolonized many areas of the Midwestern United States, prompting concern over the possible risk wolves may pose to livestock producers. To better understand the risks wolves may pose to livestock, we initiated a 3-y study examining the food habits of wolves in an agricultural area of northwestern Minnesota and their relation to depredation records of livestock losses in the same area. We collected 533 wolf feces during the non-winter seasons from 1997–1999. White-tailed deer (Odocoileus virginianus) was the most abundant food item (39.2%) of all prey items for all 3 y combined. …

Attitudes Of Rural Landowners Toward Wolves In Northwestern Minnesota, Andreas S. Chavez, Eric M. Gese, Richard S. Krannich
United States Department of Agriculture Wildlife Services: Staff Publications
The natural recolonization of gray wolves (Canis lupus) into parts of their former range in the upper Midwest of the United States has led to wolves establishing territories in semi-agricultural areas containing livestock. As part of a study on wolf–livestock relationships in a northwestern Minnesota agricultural area, we surveyed rural landowners within and outside of wolf range to assess perceptions regarding the risks wolves pose to livestock (mainly cattle). The mean response score for rural landowners to the statement “I think wolves should be allowed to exist in northwest Minnesota” was between neutral and disagree. There was no …

The United States Fish and Wildlife Service (USFWS) developed guidelines for the composition and role of endangered species recovery implementation teams, but few teams have been established and their success has not been evaluated. Using the recovery program of the red wolf (Canis rufus) as a model, we describe the genesis, function, and success of the Red Wolf Recovery Implementation Team (RWRIT) in helping guide the establishment of a viable red wolf population in eastern North Carolina. In operation since 1999, the RWRIT meets bi-annually to review USFWS progress and provide recommendations aimed at maximizing success of species …

Measurement Of The W Boson Polarization In Top Decay At Cdf At Sqrt(S)=1.8 Tev, Darin Acosta, Kenneth A. Bloom, Collider Detector At Fermilab Collaboration
Kenneth Bloom Publications
The polarization of the W boson in t→Wb decay is unambiguously predicted by the standard model of electroweak interactions and is a powerful test of our understanding of the tWb vertex. We measure this polarization from the invariant mass of the b quark from t→Wb and the lepton from W→lν whose momenta measure the W decay angle and direction of motion, respectively. In this paper we present a measurement of the decay rate (fv+A) of the W produced from the decay of the top quark in the hypothesis of V+A structure of the tWb vertex. …

Alfalfa: The Queen Of Forage Crops, It Don't Get Any Better, Warren C. Thompson
Kentucky Alfalfa and Stored Forage Conference
For anyone who has grown or used alfalfa, there is no question but that alfalfa is the best forage crop they have dealt with. Perhaps that is one reason that we in professional agriculture have given so much special interest to the crop and why it is held in such high esteem and the position it demands in research and refinement investments over the years at the private and public sectors.

Alfalfa use by dairy cattle has decreased in recent years because of excessive nonprotein nitrogen and low fiber digestibility. Ideal attributes for plant modification of alfalfa may include those that increase milk potential per acre and/or per ton, enhance digestible NDF, improve protein content and amino acid balance, improve agronomic traits for insect protection (safer forage supply), herbicide tolerance, virus resistance, drought tolerance, cold tolerance, improved mineral availability and enhanced yield. Progress in attaining these attributes will accelerate with the use of biotechnology. Livestock and hay enterprises will benefit from alfalfa that is less prone to contain mycotoxins or toxic …

In late 1997 Forage Genetics International (FGI) and Monsanto began a joint project to develop Roundup Ready alfalfa. FGI collaborated with Montana State University to produce the first transgenic Roundup Ready alfalfa plants. The same CP4 glyphosate tolerance gene that has been effectively used in developing multiple other Roundup Ready crops, was successfully inserted into an elite FGI alfalfa plant in early 1998.

Growing Alfalfa For Wildlife, Don Ball
Kentucky Alfalfa and Stored Forage Conference
Alfalfa has long been recognized as a superb forage crop, which is why it is widely grown for dairy cattle, horses, sheep, and many other types of domesticated forage-consuming animals. Reasons for its popularity include wide adaptation, excellent nutritive value, good yield potential, perennial growth habit, a long growing season, and the fact that (in association with Rhizobium bacteria) it is a nitrogen-fixing legume that does not require periodic applications of nitrogen fertilizer.
Progress Towards Sclerotinia--Resistant Varieties, Paul C. Vincelli
Progress Towards Sclerotinia--Resistant Varieties, Paul C. Vincelli
Kentucky Alfalfa and Stored Forage Conference
Sclerotinia crown and stem rot (SCSR), caused by the fungus Sclerotinia trifoliorum, is one of the most important factors limiting the success of late-summer alfalfa seedings in the region. Infections of S. trifoliorum that progress into the crown of a fall-sown alfalfa plant can kill it during winter or spring green up. Stand losses by the following spring may be insignificant (1-3%) or nearly total, with 95-99% of the stand being dead (and often even rotted away and gone by spring green-up).

Alfalfa Hay For Horses (And Horse Owners!), Laurie Lawrence, Bryan Cassill
Kentucky Alfalfa and Stored Forage Conference
Alfalfa is one of the most common hays fed to horses in Kentucky. Other hays that are often used include timothy and orchardgrass. As a legume, alfalfa has many nutritional advantages over timothy or orchardgrass. Alfalfa hay contains more protein and calcium than grass hays and thus is an excellent source of these nutrients for broodmares and growing horses. Another legume that may be useful as a hay for horses is red clover. Nutritionally, red clover has many of the same advantages as alfalfa. However, red clover has some non-nutritional characteristics which have traditionally limited its popularity with horse owners. …

Advances In Alfalfa Seed Coating, Bill Talley
Kentucky Alfalfa and Stored Forage Conference
Seed coating for alfalfa has been available since the mid to late 70’s. Over the last 30 years, advances in the industry have made it the choice of many producers. The purpose of the coatings at that time was mainly to add weight to increase the ballistic properties and to be a carrier for the rhizobia. Through research and new technology, coatings have evolved and shown great agronomic benefits. Seed coating can provide an opportunity to supply effective quantities of needed materials to each seed, which can influence both the physical property, and the microenvironment of the seed. Coatings can …
Impact Of Alfalfa In Lincoln County, Dan Grigson
Impact Of Alfalfa In Lincoln County, Dan Grigson
Kentucky Alfalfa and Stored Forage Conference
Lincoln County is located 45 miles south of Lexington, Kentucky. It is part of 3 geographical regions of the state-the outer Bluegrass, the Knobs, and the Eastern Pennyroyal area. Thus the land ranges from moderate sloping fields that can be row cropped to fields that are nearly too steep to mow. The majority of the land is best suited for hay and pasture production. The soil fertility is moderately high with limestone, sandstone, shale and siltstone parent material. The land is very well suited to growing very productive forage crops.

Teaching Stand Management Using Virtual Alfalfa Plants, S. Ray Smith, Lars Muendermann, Av Singh
Kentucky Alfalfa and Stored Forage Conference
A ‘virtual’ alfalfa plant model was developed at the University of Manitoba in Canada as part of a comprehensive grazing research project. This model shows an alfalfa plant ‘growing’ on a computer screen and the plant’s response to grazing (similar to time-lapse photography). The original model was designed and constructed by Av Singh to show the research potential of visually modeling alfalfa plant growth. The ability to visually ‘grow’ a plant on a computer screen also provides an excellent teaching and extension tool.

Medieval Warming, Little Ice Age, And European Impact On The Environment During The Last Millennium In The Lower Hudson Valley, New York, Usa, Dee Cabaniss Pederson, Dorothy M. Peteet, Dorothy Kurdyla, Tom Guilderson
United States National Aeronautics and Space Administration: Publications
Establishing natural climate variability becomes particularly important in large urban areas in anticipation of droughts. We present a well-dated bi-decadal record of vegetation, climate, land use, and fire frequency from a tidal marsh in the Hudson River Estuary. The classic Medieval Warm Period is evident through striking increases in charcoal and Pinus dominance from ~800–1300 A.D., paralleling paleorecords southward along the Atlantic seaboard. Higher inputs of inorganic sediment during this interval suggest increased watershed erosion during drought conditions. The presence of the Little Ice Age ensues with increases in Picea and Tsuga, coupled with increasing organic percentages due to …

Optical Detection Of Ultracold Neutral Calcium Plasmas, Elizabeth Ann Cummings
Optical Detection Of Ultracold Neutral Calcium Plasmas, Elizabeth Ann Cummings
Theses and Dissertations
We demonstrate an optical method to detect calcium ions in an ultracold plasma. We probe the plasma with a 397 nm laser beam tuned to a calcium ion transition. The probe laser beam is focused to a 160 µm waist allowing fine spatial resolution. Ions are detected by measuring fluorescence using a Photo-Multiplier Tube (PMT). The signal, an average of 4000 acquisitions, has a temporal resolution of 120 ns. We present the details of this method, potential improvements, and prospects of imaging the expanding plasma ions. We also present preliminary work on spatially resolved absorption measurements, as well as additional …

Evidence For Static Stress Changes Triggering The 1999 Eruption Of Cerro Negro Volcano, Nicaragua And Regional Aftershock Sequences, M. Diez, P. C. La Femina, Charles B. Connor, W. Strauch, Tenorio V. Tenorio
Geology Faculty Publications
Remarkable evidence of coupling between tectonic and magmatic events emerges from investigation of three tectonic earthquakes, aftershock sequences and eruption of Cerro Negro volcano, Nicaragua in 1999. Here, we explain this coupling through static stress changes following three Mw 5.2 earthquakes. We use focal mechanism solutions to estimate fault system geometry and magnitude of slip from these events, which are then used to calculate the change in minimum horizontal principal stress (σ3) for the region and the change in Coulomb failure stress on optimally oriented fault planes. Results of these simulations indicate that σ3 was reduced by …

Long Period Variables In The Globular Cluster 47 Tuc: Radial Velocity Variations, Thomas Lebzelter, Peter R. Wood, Kenneth H. Hinkle, Richard R. Joyce, Francis C. Fekel
Information Systems and Engineering Management Research Publications
We present near infrared velocity curves for 12 long period variables (LPVs) in the globular cluster 47 Tuc (NGC 104). New light curves are also presented for these variables. Results are compared with the period-luminosity sequences occupied by the LPVs in the LMC. Sequence C variables (fundamental mode pulsators) have larger velocity amplitudes than sequence B variables (first overtone pulsators). We show that, at similar luminosities, higher mass loss rates are associated with larger pulsation amplitudes. One variable (V18) does not fit the normal period luminosity sequences and it has an unusually large amount of circumstellar dust, suggesting that it …

Excited states in 166Hf were populated in the β+/∈ decay of 166Ta and studied through off-beam γ –ray spectroscopy at the Yale moving tape collector. New coincidence data found no support for two previously reported excited 0+ states and led to a substantially revised level scheme. Similarities between the revised level scheme of 166Hf and the X(5) critical point symmetry are discussed, and the extent of X(5) behavior in this mass region is explored through the W and Os isotopes. Among X(5) candidates with N > 90, good agreement is observed for most energies and …
