Dicamba Spray Drift as Influenced by Wind Speed and Nozzle Type
(Cambridge Univ Press, 2017-09-01)
With the release of dicamba-resistant crops, it is necessary to understand how technical and environmental conditions affect the application of dicamba. This study sought to evaluate drift from dicamba applications through ...
EFFECT OF DRYING TEMPERATURE AND AIR SPEED ON CICHORIC ACID AND ALKYLAMIDE CONTENT OF ECHINACEA PURPUREA
(INT SOC HORTICULTURAL SCIENCE, 2002)
The objective of the investigations was to determine the effect of drying temperature and air speed on cichoric acid and alkylamide content in one-year-old Echinacea purpurea aerial biomass. The samples were obtained from ...
Comparison of environmental indicators of two aviaries for laying Hens
The aim of this paper is to compare the environmental indicators of two housing systems for laying hens. The roof of aviary I was built with cement-asbestos tile, ridge vent, and long eaves. The roof of aviary 2 was built ...
Influence of the environment on behavior patterns of laying hens kept in cages
The aim of this paper is to verify the correlation between environmental indicators and behaviors expressed by laying hens kept in cages. The birds react to a severe environment through their behaviors, end the behaviors ...
Laser ultrasonics system for measurement of speed of sound in gases
In this work we developed a setup to measure the speed of sound in gases using a laser ultrasonics system. The mentioned setup is an all optical system composed by a Q-switched Nd:YAG laser to generate the sound waves, and ...
