Wild blueberry producers apply fungicide uniformly without considering significant bare spots in the field. The wrong or over use of fungicide in bare spots results in an increased cost of production and threatens the environment. An automated prototype variable rate (VR) sprayer was used for spot-application (SA) of Chlorothalonil (Bravo®) fungicide in a(More)
The wild blueberry industry is spending over $80 million CAD per year on agrochemicals for 93 000 ha under production in North America. A pressing need to reduce agro-chemical usage and production cost has resulted in the development of a smart sprayer for spot-application of agrochemicals in wild blueberry fields. This paper encompasses the economic(More)
Wild blueberry (Vaccinium angustifolium Ait.) fields in the north east Canada are naturally grown in a course textured thin layer of soil and below this layer is a soilless layer of gravel. The root zone depth of this crop varies from 10 to 15 cm. Investigating the depth to the gravel layer below the course textured soil is advantageous, as it affects the(More)
An automated sensing and control system (hardware and software) was developed for real-time spot-application of granular fertilizer in mowed wild blueberry fields. The custom hardware system was incorporated into a commercial pneumatic granular fertilizer spreader. Custom software for the sensing and control system was developed by combining color(More)
Wild blueberry fields have a significant proportion of bare spots/weed patches, scattered throughout the field, emphasizing the need for targeted fertilizer applications. The existing prescription map-based variable rate (VR) spreader cannot take account of the presence of small, irregularly shaped bare spots/weed patches during fertilization as only each(More)
Omental torsion is a rare cause of acute abdomen. It usually presents with acute onset right-sided abdominal pain. Adult male between 40 and 50 years of age and obesity are the most common risk factor amongst others. Clinical diagnosis is challenging and difficult to differentiate from more common clinical pathologies such as acute appendicitis and/or acute(More)
, we wish to notify the readers on the hazards caused by instant gas geysers. Two such cases presented to us last winter. Two young patients a 19 years old female admitted on 6th of February 2014, and 21 years old male admitted on 19th January, 2014 while taking a bath were found unconscious in the bathroom and presented to the emergency. These bathrooms(More)
