Stalk cutter device and method of use

The stalk cutter device and method of use thereof obtains a desired length of plant stalk, particularly a cornstalk, from a desired distance from the ground. The stalk cutter device includes a pair of handles pivotally connected to a pair of pruning type of cutters. A support rod is mounted through the pivot connections of the cutters and extends laterally a desired distance from the lower cutter to support the device at the desired height to cut the desired portion of the stalk

How Can We Best Test The Effects Of Pollutants And Changes On The Animals And Plants Of Chesapeake Bay?

The animals and plants of the Bay, and the processes in which they are involved, are the basis for almost every use and desirable quality of the Bay. They provide both commercial and recreational fisheries, assimilate some quantities of wastes, contribute to esthetic quality, provide a favorable environment for many birds and mammals and feed all of the species which are used by man. However, the biota are directly or indirectly affected by many human activities - by maritime transport, recreational activities, agricultural production, waste discharges, domestic development, engineering activity, and other land-based activities. Therefore, the ultimate and most important question to be considered in evaluating any new pollutant or proposed environmental modification is - What effect will it have on the biota?https://scholarworks.wm.edu/vimsbooks/1175/thumbnail.jp

Diagnosis and Conservative Treatment of Skeletal Class III Malocclusion with Anterior Crossbite and Asymmetric Maxillary Crowding

A 28-year-9-month male presented for orthodontic consultation for skeletal Class III malocclusion (ANB -30) with a modest asymmetric Class II/III molar relationship, complicated by an anterior crossbite, deep bite, and 12mm of asymmetric maxillary crowding. Despite the severity of a malocclusion, Discrepancy Index (DI) = 37, the patient desired non-invasive camouflage treatment. Lin’s 3-Ring diagnosis revealed that treatment without extractions or orthognathic surgery was a viable approach. Arch length analysis indicated that differential interproximal enamel reduction (IPR) could resolve the crowding and midline discrepancy, but a miniscrew in the infrazygomatic crest (IZC) was needed to retract the right buccal segment. The patient accepted the complex, staged treatment plan with the understanding that it would require ~3.5 years. Fixed appliance treatment with passive self ligating (PSL) brackets, early light short elastics (ELSE), bite turbos (BTs), IPR, and IZC retraction opened the vertical dimension of occlusion (VDO), improved the ANB 20 and achieved an excellent alignment, as evidenced by a CRE of 26 and a Pink and White (P&W) dental esthetic score of 3. The worksheets for the DI, CRE, and P&W scores are attached within this case report

Investigating the effects of planting date and Aphis gossypii management on reducing the final incidence of cotton leafroll dwarf virus

This is the first study to research management strategies for cotton leafroll dwarf virus (CLRDV) in the southeastern U.S. The efficacy of aphid vector management to reduce final CLRDV incidence was investigated concurrent with efforts to monitor aphid population dynamics and timing of CLRDV spread. Adjusting the planting date and insecticide applications did not reduce the final incidence of CLRDV, which was confirmed in 60–100% of plants per plot using RT-PCR. Aphid population density was reduced, but not eliminated with foliar insecticide applications. Aphis gossypii was the only species observed on cotton and was the dominant species collected in pan traps. Three distinct periods of virus spread were detected with sentinel plants including early, mid-and late-season. Most virus spread occurred during large aphid dispersal events

Johnson Noise Thermometry for Advanced Small Modular Reactors

Temperature is a key process variable at any nuclear power plant (NPP). The harsh reactor environment causes all sensor properties to drift over time. At the higher temperatures of advanced NPPs the drift occurs more rapidly. The allowable reactor operating temperature must be reduced by the amount of the potential measurement error to assure adequate margin to material damage. Johnson noise is a fundamental expression of temperature and as such is immune to drift in a sensor s physical condition. In and near core, only Johnson noise thermometry (JNT) and radiation pyrometry offer the possibility for long-term, high-accuracy temperature measurement due to their fundamental natures. Small, Modular Reactors (SMRs) place a higher value on long-term stability in their temperature measurements in that they produce less power per reactor core and thus cannot afford as much instrument recalibration labor as their larger brethren. The purpose of this project is to develop and demonstrate a drift free Johnson noise-based thermometer suitable for deployment near core in advanced SMR plants

Glubodies: randomized libraries of glutathione transferase enzymes

AbstractBackground: The immunoglobulin framework has been mutagenized to engineer recombinant libraries of proteins as potential diagnostics and novel catalysts, although the often shallow binding cleft may limit the utility of this framework for binding diverse small organic molecules. By contrast, the glutathione S-transferase (GST) family of enzymes contains a deep binding cleft, which has evolved to accommodate a broad range of hydrophobic xenobiotics. We set out to determine whether GST molecules with novel ligand-binding characteristics could be produced by random mutagenesis of segments of the binding cleft.Results: We have identified two ligand-recognition segments (LRSs) in human GST P1, which are near the active site in the folded protein, but have characteristics indicating that the integrity of their sequence is not essential for the overall structure or activity of the protein. Libraries of GST P1-derived proteins were produced by substituting randomized sequences for an LRS or inserting random sequences into an LRS. The recombinant proteins in the libraries, collectively designated as ‘glubodies,’ generally retain enzymatic activity but differ markedly both from each other and from the parent enzyme in sensitivity to inhibition by diverse small organic compounds. In some instances, a glubody is inhibited by completely novel structures.Conclusions: We have shown that a non-antibody framework can be used to create large libraries of proteins with a wide range of binding specificities for small organic molecules. The glubodies provide a rich source of data for correlating the structural and functional features of proteins relevant to ligand binding. The criteria applied for identifying an LRS in GST P1 are generally applicable to other protein frameworks
