Abstract Effects of egg retention on movement and dispersal activity of Trichogramma principium (Hymenoptera, Trichogrammatidae) females were investigated under laboratory conditions. Individual females were observed during one minute in the absence of hosts. Movement activity and dispersal rate were estimated by the length of the track and by the distance from the start point, respectively. Be...

Evidence has demonstrated that the use of dynamic ultrasound guidance (USG) for central venous catheter (CVC) significantly decreases attempts, failures, and complication rates. Despite national organizations recommending the use of USG and its increasing availability, USG is used inconsistently and non-uniformly. We sought to determine if an online training module for CVC insertion with ultras...

Greve and Bianchini (2006) have posed the question, “Should the Retention trial of the Test of Memory Malingering be optional?” The answer to this question is important given the finding by Slick, Tan, Strauss, and Hultsch (2004) that the Test of Memory Malingering (TOMM; Tombaugh, 1996) is one of the most commonly used malingering tests among surveyed psychologists. Greve and Bianchini (2006) ...

A rhesus monkey was tested in an auditory list memory task with blocked and mixed retention delays. Each list of four natural or environmental sounds (from a center speaker) was followed by a retention delay (0, 1, 2, 10, 20, or 30 sec) and then by a recognition test (from two side speakers). The monkey had been tested for 12 years in tasks with blocked delays. An earlier (4 years prior) blocke...

AbstractThis study aimed at examining the effect of pictorial presentation of vocabulary on EFL students’ retention relying on Dual Coding Theory and Additivity Hypothesis, both of which emphasize the additive effect of images on recall. To that end, 63 students who were in grade three of high school served as the participants of the study. They were randomly divided into three groups of still ...

The purpose of this study was to evaluate and compare the retention strength of five cement types commonly used in implant-retained fixed partial dentures, before and after compressive cyclic loading. In five solid abutments screwed to 5 implant analogs, 50 metal Cr-Ni alloy copings were cemented with five luting agents: resin-modified glass ionomer (RmGI), resin composite (RC), glass ionomer (...

We develop a simple framework for the analysis of models with dynamic treatment e ects, accounting for both dynamic selection and that the e ect of treatment may di er over time. In the context of our application, the framework permits students who are retained in kindergarten to di er in unobservable ways from students who are retained in second grade. Furthermore, being retained in rst grade ...

In a refrigeration cycle, some of the oil circulates and resides in cycle components. The worst scenario of oil circulation in the cycle is where a large amount of oil is retained outside the compressor. High oil retention causes system performance and reliability degradations. The purpose of this study is to experimentally clarify oil retention and pressure drop characteristics due to the pres...

BACKGROUND The anterior cingulate cortex (ACC) and medial thalamus (MT) are two of the main components of the medial pain pathway that subserve the affective aspect of pain. The hypothesis of the present study was that the ACC is involved in short-term aversive information processing and that the MT is critical for encoding unconditioned nociceptive information. The roles of these two component...

BACKGROUND Self-directed BLS-training, using a personal training manikin with video has been shown to be as effective as instructor-led training. This has not previously been investigated for AED-training. MATERIALS AND METHODS This prospective, randomized study with a non-inferiority design compared traditional instructor-led training with three DVD-based AED-training methods (2.5min DVD wit...
