 The stimulatory effect of earthworms (Lumbricus terrestris L.) on soil microbial activity was studied under microcosm-controlled conditions. The hypothesis was tested that microbial stimulation observed in the presence of a soil invertebrate would be due to the utilization of additional nutritive substances (secretion and excretion products) that it(More)
A head-up display (HUD) is a projection of symbology into the pilot’s forward field of view that enables the pilot to monitor the instrumentation while, theoretically, also viewing the external domain. Although the HUD has been shown to improve flight per formance, there are perceptual and cognitive issues that need to be addressed. This ar ticle reviews(More)
BACKGROUND Fluoroscopic guidance is frequently utilized in performing various types of interventional techniques. The major purpose of fluoroscopy is accurate needle placement to ensure target specificity and accurate delivery of the injected drug. However, radiation exposure may be associated with risks to physician, patient, and personnel. Multiple(More)
We investigate the effectiveness of sonification (continuous auditory display) for supporting patient monitoring while reducing visual attentional workload in the operating theatre. Non-anaesthetist participants performed a simple continuous arithmetic task while monitoring the status of a simulated anaesthetised patient, reporting the status of vital signs(More)
We have identified five patients with severe combined immunodeficiency (SCID) who developed multiple monoclonal serum immunoglobulin components (multiclonal gammopathy) following bone marrow transplantation. Four patients received haploidentical bone marrow stem cells depleted of T cells and other mature marrow cells by soy lectin agglutination and/or sheep(More)
This study of was conducted to explore the contribution of attentional skills to early language, and the influence of early language markers on the development of attention, simultaneously examining the impact of parent-child interaction factors (reciprocity/synchrony and sensitivity/responsivity), including their potential moderator effects. All children(More)
The placement of nutrition information on the front of food packages has been proposed as a method of providing simplified and visible nutrition information. This study aimed to determine the most acceptable and effective front-of-pack food labelling system for Australian consumers. Consumers' preferences and ability to compare the healthiness of mock food(More)
To study the long-term effects of exposure to maternal hyperglycemia and insulin deficiency in utero, we used the syngeneic islet transplanted streptozotocin-diabetic rat model of diabetes in pregnancy and examined insulin secretion and action in 6-month-old offspring. Female rats were rendered diabetic with streptozotocin and then transplanted with 2500,(More)
OBJECTIVE To investigate consumers' understanding of terms commonly used to provide guidance about frequency and quantity of food consumption. METHODS A survey of 405 shoppers explored how frequently consumers thought food labeled with the terms "eat often," "eat moderately," "eat occasionally," "a sometimes food," and "an extra food" should be eaten. In(More)
The design of new human machine systems, and the analysis of current human machine systems pose interesting dilemmas for the human factors specialist. Cognitive Work Analysis (CWA), (Vicente, 1999; Rasmussen, Pejtersen, & Goodstein, 1994) is an analytical framework for modeling both work environments and safe, flexible strategies workers can use to act upon(More)
