the experiment in this study was conducted as a completely randomized block design with ten treatments and four replications. treatments included: to- control, t1- 50g of zn per tree as broadcast application, t2-100g zn per tree, broadcast application, t3- 200g zn per tree as broadcast application, t4- 50 g zn per tree as band application, t5- 50g zn per tree, band application, t6-100g zn per t...
Abstract: In this paper, we obtain analogues of Jørgensen’s inequality for non-elementary groups of isometries of quaternionic hyperbolic n-space generated by two elements, one of which is loxodromic. Our result gives some improvement over earlier results of Kim [9], Markham [14] and Cao [2]. These results also apply to complex hyperbolic space and give improvements on results of Jiang, Kamiya ...
Koebe’s Retrosection Theorem [8] states that every closed Riemann surface can be uniformized by a Schottky group. In [10] Marden showed that non-classical Schottky groups exist, and a first explicit example of a non-classical Schottky group was given by Yamamoto in [14]. Work on Schottky uniformizations of surfaces with certain symmetry has been done by people such as Hidalgo [7]. The natural q...
While several existing Delaunay refinement algorithms allow acute 3D piecewise linear complexes as input, algorithms producing conforming Delaunay tetrahedralizations (as opposed to constrained or weighted Delaunay tetrahedralizations) often involve cumbersome constructions and are rarely implemented. We describe a practical construction for both “collar” and “intestine”-based approaches to thi...
GPS tracking collars, the current method of noninvasively studying large mammals, give limited and undetailed data. The ANIMA project seeks to improve upon tracking collars by creating a tag that integrates a GPS with a magnetometer and an accelerometer. The additional sensors will give information about animal physiology and daily behaviors. To remain a commercially viable option to research s...
OBJECTIVE To evaluate the effects of spinal immobilization on healthy participants. METHODS A systematic review of randomized, controlled trials of spinal immobilization on healthy participants. RESULTS Seventeen randomized, controlled trials compared different types of immobilization devices, including collars, backboards, splints, and body strapping. For immobilization efficacy, collars, ...
This paper uses Regression Discontinuity Design to study the wage effects of a reform that introduced unjust dismissal costs for firms below 15 employees, while leaving firing costs unchanged for bigger firms. We address the endogeneity of the treatment status due to workers and firms sorting around the 15 employees threshold by applying IV techniques on a sample of exogenously displaced worker...
Since 1974 the Fish and Wildlife Service has studied a "toxic collar" to poison coyotes that attack collared sheep and goats. The collar patent (McBride 1974) indicates that the same collar could deliver chemicals to repel coyotes, thus saving both the coyote and the livestock. This report summarizes our experience with nonlethal tests of collars. During collar tests with 10 different toxicants...
