EC17-11-80 Nebraska Outdoor Education Series: Plant a Tree

Not all trees or shrubs can find a home in your yard or apartment. Help your child to discover a home for the tree or shrub he or she grows or receives. The greatest benefit of this Plant-A-Tree project is being close to a living plant. This project will: introduce five tree planters - one from each area of Nebraska, discuss the parts of tree seeds, give examples of how tree seeds travel, discuss preparation of soil, demonstrate how to grow a seedling tree from seed, demonstrate how to transplant a tree, and offer suggestions for activities and exhibits

June 14 tsunami warning response in Lincoln County

On June 15, 2005, a 7.2 earthquake occurred off the coast of Northern California. The earthquake was widely felt. A tsunami warning was issued to the West Coast. This document contains correspondence between a citizen and Lincoln County Commissioners regarding the County's response to the emergency, and offering suggestions for improvement.

High-pressure structural investigation of several zircon-type orthovanadates

Room temperature angle-dispersive x-ray diffraction measurements on zircon-type EuVO4, LuVO4, and ScVO4 were performed up to 27 GPa. In the three compounds we found evidence of a pressure-induced structural phase transformation from zircon to a scheelite-type structure. The onset of the transition is near 8 GPa, but the transition is sluggish and the low- and high-pressure phases coexist in a pressure range of about 10 GPa. In EuVO4 and LuVO4 a second transition to a M-fergusonite-type phase was found near 21 GPa. The equations of state for the zircon and scheelite phases are also determined. Among the three studied compounds, we found that ScVO4 is less compressible than EuVO4 and LuVO4, being the most incompressible orthovanadate studied to date. The sequence of structural transitions and compressibilities are discussed in comparison with other zircon-type oxides.Comment: 34 pages, 2 Tables, 11 Figure

Plurisubharmonic polynomials and bumping

We wish to study the problem of bumping outwards a pseudoconvex, finite-type domain \Omega\subset C^n in such a way that pseudoconvexity is preserved and such that the lowest possible orders of contact of the bumped domain with bdy(\Omega), at the site of the bumping, are explicitly realised. Generally, when \Omega\subset C^n, n\geq 3, the known methods lead to bumpings with high orders of contact -- which are not explicitly known either -- at the site of the bumping. Precise orders are known for h-extendible/semiregular domains. This paper is motivated by certain families of non-semiregular domains in C^3. These families are identified by the behaviour of the least-weight plurisubharmonic polynomial in the Catlin normal form. Accordingly, we study how to perturb certain homogeneous plurisubharmonic polynomials without destroying plurisubharmonicity.Comment: 24 pages; corrected typos, fixed errors in Lemma 3.3; accepted for publication in Math.

An Integral Kernel for Weakly Pseudoconvex Domains

A new explicit construction of Cauchy-Fantappi\'e kernels is introduced for an arbitrary weakly pseudoconvex domain with smooth boundary. While not holomorphic in the parameter, the new kernel reflects the complex geometry and the Levi form of the boundary. Some estimates are obtained for the corresponding integral operator, which provide evidence that this kernel and related constructions give useful new tools for complex analysis on this general class of domains

Oiled birds : how to search for and capture oiled birds at Oregon intertidal areas

This is written primarily as a step-by-step guide for the person(s) responsible for organizing searches of oiled birds and/or for training volunteers to handle oiled birds. It also gives details that can be useful to anyone that catches or handles birds, whether oiled or not. This monograph is based on the author's field experience after an oil spill along the Oregon Coast. But its findings are also applicable elsewhere, if the appropriate governmental agencies are substituted as necessary for the U.S. Fish and Wildlife Service or Oregon Department of Fish and Wildlife. Perhaps the most significant point made is that a bird's legs should be fully supported when it is picked up. If supported, the bird remains calmer, and the bird won't be able to use its feet to scratch a volunteer. Photographs illustrate the correct way to handle an oiled bird from capture until it is transported in a box. This publication does NOT include information about rehabilitating oiled birds
