Herbicide damage to sensitive crops

"Over the past several decades in Missouri and other states, the greatest and most widespread uses of herbicides have been in the production of row-crops and forages and in the clearing of brush for pasture improvement."--First page.John Lower and Larry Lockshin (Department of Horticulture) and L.E.

Nitrogen and Potassium Interact to Shape a Yield Response Surface

In a field experiment with banana, fertilizer variables were applied systematically in strips across the blocks so that N increased gradually from none to large quantities in one direction, while K increased gradually perpendicular to the N fertilizer. An aerial view of the blocks and a plot of banana yields as influenced by the variables illustrate the interaction of the nutrients applied

Equation of state of forsterite

Shock wave data for pure forsterite with initial bulk densities of 2.6 and 3.1 g/cm^3 are obtained to 0.370 Mb by impacting series of specimens with tungsten alloy plates that are launched at speeds of up to 2.3 km/sec with a high-performance propellant gun. The onset of a shock-induced phase change, probably corresponding to the forsterite-‘post spinel’ phase change is observed at 0.280±0.025 Mb. Because of the low shock temperatures, the transition is believed to be limited by the reaction rate and this pressure value should be taken only as an upper limit. Adiabats derived from the Hugoniot data for the forsterite phase are fit to the two-parameter finite strain Birch-Murnaghan equation and to two simple ionic equations of state. The Birch-Murnaghan form of the equation of state gives a zero-pressure bulk modulus (1.29 Mb) that agrees more closely with the ultrasonic data than the modulus obtained from the ionic equations of state. An unusual relaxation effect, in which the elastic shock precursor velocity varies from 5.8 to 9.5 km/sec, is also observed. The characteristic time of the relaxation process appears to be less than 1 μsec

Fully Differential Cross Sections for Electron-Impact Excitation-Ionization of Aligned D₂

We examine fully differential cross sections for 176 eV electron-impact dissociative excitation-ionization of orientated D2 for transitions to final ion states 2sσg, 2pσu, and 2pπu. In previous work [Phys. Rev. A 88, 062705 (2013)PLRAAN1050-294710.1103/PhysRevA.88.062705], we calculated these cross sections using the molecular four-body distorted wave (M4DW) method with the ground-state D2 wave function being approximated by a product of two Dyson 1s-type orbitals. The theoretical results were compared with experimental measurements for five different orientations of the target molecule (four in the scattering plane and one perpendicular to the scattering plane). For the unresolved 2sσg + 2pπu final states, good agreement with experiment was found for two of the five measured orientations, and for the 2pσu final state, good agreement was found for three of the five orientations. However, theory was a factor of 200 smaller than experiment for the 2pσu state. In this paper, we investigate the importance of the approximation for the molecular ground-state wave function by repeating the M4DW calculation using a better variational wave function for the ground state

Creating and assessing a web site for science students

vi, 20 leaves ; 29 cm. + 1 computer optical disc. --This project entitled Creating and Assessing a Web Site for Science Students was created to facilitate the use of the Internet in the teaching and learning of Science at Lindsay Thurber Comprehensive High School. In order to accomplish this, different avenues for creating web pages were explored and a web site creation program called ADOBE Go Live 5.0 was learned and used to built the Science Department web site. The site was then uploaded to the district server and attached to the Lindsay Thurber web page. Teachers within the Science department introduced the site to students, and the students were given several months to use the site. Students were surveyed to determine the effectiveness of the site, how it was being used, and how the site might be improved for future use. The results of the survey show that students think the web site is well designed; yet it is not being used in a very significant way. Having students and teachers use the site is critical to realizing the value of this project. The challenge that lies ahead is getting students and teachers to use the site as a tool that can make teaching and learning of Science more efficient. This challenge will be met by involving more teachers in the vision of this project, posting information for students that they can only get off the site, and implementing changes to make the site easier to use
