Roadside vegetation management final report for the period July 1986 to June 1991 (FHWA-OK-91-10) 2147

The information contained within this report addresses: (1) Research -- involving the use of herbicides and plant growth regulators for roadside vegetation management; (2) Maintenance -- implementing research results into an operational phase of the Oklahoma Department of Transportation (ODOT) maintenance program; and (3) Training -- conducting pesticide applicator certification programs and providing continuing educational programs for these certified applicators. The following are recommendations and/or conclusions based upon the research results. (1) Roundup rates may be reduced from 0.75 to 0.62 lb. ai./A in the western and central portions of Oklahoma while maintaining 90% control of johnsongrass. In the eastern one-third of the state, rates of Roundup should be maintained at 0.75 lb. ai./ A to achieve the 90% level of control. (2) When applied at equal rates, SC-0224 and Roundup provide equal con tro l of johnsongrass. (3) The additive Frigate, significantly increases the activity of Roundup and Roundup plus Oust treatments. (4) A single application of Arsenal applied at 1.2 lb. ai. in combination with Oust at 0.047 lb. ai. applied in 40 gallons of water per acre will effectively control bermudagrass encroachment into paved roadside shoulders and seams when applied in late May or June to actively growing bennudagrass. (5) Musk this tle can be effectively controlled with Transline at 0.125 to 0.25 lb. ai. in 25 to 50 gallons of water per acre applied during March through April when thistle plants are actively growing and prior to bolti ng (flowering). (6) Vision, a plant growth regulator, applied under an EUP label suppresses of bermudagrass growth along roadsides. S everal larg e-scale demonstrations were initiated throughout the duration of this project and are described as follows: Musk thistle control with Transline; johnsongrass control with Roundup+ Oust and/or Frigate; c on trol of Kudzu with Arsenal; bermudagrass encroachmen t control with Arsenal; silver bluestem control with Roundup, alone, or in combination with Oust and/or Frigate; bermudagrass canopy height su ppression with Vision or Poast plus a crop oil. Training activities included certification of 59 1 new ODOT herbi cide applicators and providing continuing educational programs for 1354 ODOT certified applicators.Final Report July 1986-June 1991N

Roadside vegetation management final report for the period December 1991 to September 1996 (FHWA-ODOT-96-05) 2187

The infonnation contained within this report addresses: (1) Research - involving the use of experimental, newly labeled and traditionally available herbicides in combination with mowing for roadside vegetation management; (2) Maintenance implementation of research results into an operational phase of the Oklahoma Department of Transportation ·s (ODOT) maintenance program. as well as performing on-site visits, telephone and written consultation to ODOT personnel; and (3) Training - conducting pesticide applicator certification programs, and providing continuing education programs for these certified applicators. The following are conclusions based on our research: (1) Campaign herbicide or Roundup plus 2,4-D may be used postemergence in place of atrazine or diuron applied pre-emergence for the control of winter annual grasses and broadleaf weeds. Tlllling of herbicide application is critical. (2) Ammonium sulfate may be added to either Campaign herbicide or the combination treatment of Roundup + 2,4-D amine to i?lprove control of winter annual weeds. This product addition may allow end users to reduce use rates of these herbicides. (3) Primo plus Oust may be used for temporary growth and seedhead suppression of common bermudagrass on roadsides; additional product labeling will be required to implement this treatment into the maintenance phase of ODOTs vegetation management'program. (4) The product Plateau., when combined with Roundup, will provide an acceptable level of both seedling and rhizome johnsongrass control (minimum of 80% control) in common bermudagrass roadsides with potential to reduce phytotoxicity as compared to the traditional Oust plus Roundup herbicide treatment. Several research plot tours, meetings, sprayer calibration workshops, musk thistle head weevil collection/release days as well as herbicide/fertilizer demonstrations were conducted throughout the duration of this project in order to implement current research information into an operational phase of ODOTs roadside vegetation management program. Training achievements included the execution of 12 pesticide applicator certification schools resulting in 146 new herbicide applicators becoming certified. A total of 68 continuing education programs were conducted with 2, 795 ODOT certified applicators attending over a 5 year period. Numerous training information sheets were developed and provided to applicators during workshops.Final Report, December 1991-September 1996N

Roadside vegetation management guidelines

Integrated Roadside Vegetation Management (IRVM) i s a collective process that uses the most appropriate scientifically-based vegetation management techniques to meet the department' s goals in both an environmentally and economically sound manner. IRVM recognizes that every component of a program can be greatly dependent upon the other components. Whether cultural, chemical or biological, all components are used to manipulate the roadside plant community during a short period of time but with longterm goals. If the guidelines in this manual are followed, they will help ensure that the department is accountable and that goals are met as efficiently and economically as possible.N

Full surface examination of small spheres with a computer controlled scanning electron microscope

This report discusses a computer automated stage and Scanning Electron Microscopy (SEM) system for detecting defects in glass spheres for inertial confinement laser fusion experiments. This system detects submicron defects and permits inclusion of acceptable spheres in targets after examination. The stage used to examine and manipulate the spheres through 4..pi.. steradians is described. Primary image recording is made on a roster scanning video disc. The need for SEM stability and methods of achieving it are discussed

Suggestion, hypnosis and hypnotherapy: a survey of use, knowledge and attitudes of anaesthetists

Publisher's copy made available with the permission of the publisher © Australian Society of AnaesthetistsClinical hypnosis is a skill of using words and gestures (frequently called suggestions) in particular ways to achieve specific outcomes. It is being increasingly recognised as a useful intervention for managing a range of symptoms, especially pain and anxiety. We surveyed all 317 South Australian Fellows and trainees registered with ANZCA to determine their use, knowledge of, and attitudes towards positive suggestion, hypnosis and hypnotherapy in their anaesthesia practice. The response rate was 218 anaesthetists (69%). The majority of respondents (63%) rated their level of knowledge on this topic as below average. Forty-eight per cent of respondents indicated that there was a role for hypnotherapy in clinical anaesthesia, particularly in areas seen as traditional targets for the modality, i.e. pain and anxiety states. Nearly half of the anaesthetists supported the use of hypnotherapy and positive suggestions within clinical anaesthesia. Those respondents who had experience of clinical hypnotherapy were more likely to support hypnosis teaching at undergraduate or postgraduate level when compared with those with no experience.http://www.aaic.net.au/Article.asp?D=200408

Simple choreographies of the planar Newtonian NN-body Problem

In the $N$-body problem, a simple choreography is a periodic solution, where all masses chase each other on a single loop. In this paper we prove that for the planar Newtonian $N$-body problem with equal masses, $N \ge 3$, there are at least $2^{N-3} + 2^{[(N-3)/2]}$ different main simple choreographies. This confirms a conjecture given by Chenciner and etc. in \cite{CGMS02}.Comment: 31pages, 6 figures. Refinements in notations and proof

Introduction of Empirical Topology in Construction of Relationship Networks of Informative Objects

Understanding the structure of relationships between objects in a given database is one of the most important problems in the field of data mining. The structure can be defined for a set of single objects (clustering) or a set of groups of objects (network mapping). We propose a method for discovering relationships between individuals (single or groups) that is based on what we call the empirical topology, a system-theoretic measure of functional proximity. To illustrate the suitability and efficiency of the method, we apply it to an astronomical data base

Controllability on infinite-dimensional manifolds

Following the unified approach of A. Kriegl and P.W. Michor (1997) for a treatment of global analysis on a class of locally convex spaces known as convenient, we give a generalization of Rashevsky-Chow's theorem for control systems in regular connected manifolds modelled on convenient (infinite-dimensional) locally convex spaces which are not necessarily normable.Comment: 19 pages, 1 figur
