Banker plants with Aphidius colemani Viereck were tested in greenhouses in Massachusetts and New York for control of cotton aphid Aphis gossypii Glover, and green peach aphid Myzus persicae (Sulzer) on 2 spring flower crops, pansies ( Viola tricolor hortensis ) and Marguerite daisies ( Argyranthemum hybrid). Banker plants consisted of pots of barley plants infested with the bird cherry-oat aphi...

Wolves (Canis lupus) in North America are considered obligate predators of ungulates with other food resources playing little role in wolf population dynamics or wolf prey relations. However, spawning Pacific salmon (Oncorhyncus spp.) are common throughout wolf range in northwestern North America and may provide a marine subsidy affecting inland wolf-ungulate food webs far from the coast. We co...

Objectives: This study reviews the impact of living in a high-rise building or in a fl at on an upper storey on the development and health of children. Methods: A literature search was conducted to identify original English (from PubMed, dated 1960–2008) and Japanese (from ‘Ichushi-Web’, dated 1983–2008) studies that have investigated the relationship between high-rise living and children’s dev...

Given the extent of tropical forest deforestation and as a number of conservation programmes and local communities rely on forest fragments, it has become important to understand how fragment exploitation by local communities affects forest structure and function. The effects of forest exploitation on forest structure and status of forest fragments were investigated in 20 nonreserved forest fra...

This paper summarize the principles main methods for structural dynamic identification and presents the experiences in using operational modal analysis techniques in Civil Engineering field. Shown black-box modelling of system for describes the input-output relation of the system and given its application to 11 storey reinforced concrete building. The monitoring, experimental details and data-p...

The traditional Extended Kalman filter (EKF) is a useful tool for structural parameter identification with limited observations. It is, however, not applicable when the excitations on the structure are unknown or the excitation locations are not monitored. A novel Extended Kalman filter approach referred to as the General Extended Kalman filter with unknown inputs (GEKF-UI) is proposed to estim...

In this paper, first steps are taken towards characterizing rank-decorated lattices of cyclic flats Z(M) that belong to matroids M can be represented over a prescribed finite field Fq. Two natural maps from the lattice minor given. Binary characterized via their flats. It is shown simple binary matroid without isthmuses atomic.
