Background: Neutron contamination in our environment can cause harmful biological effects on human body. Therefore, many efforts have been made to construct a neutron dosimeter to estimate the received dose. Objective: To design a simple neutron dosimeter. Methods: The primary dosimeter had 3He as a spherical thermal neutron detector encircled by paraffin 10 cm in radius. Then, the paraffin sph...

Background. The reactive abilities of goalkeepers are crucial and may directly impact match results. Therefore, research on factors that may enhance goalkeeper performances during diving tasks (DT) and how these factors are mediated would provide valuable information for coaches and goalkeepers. Objectives. The purpose of this investigation was to: (i) assess the impact of caffeine consumption...

BACKGROUND Double-triggering (DT) is a frequent type of patient-ventilator asynchrony and has potentially severe consequences, such as alveolar overdistention or the generation of intrinsic PEEP. However, the first breath of DT could be patient-triggered (DT-P), auto-triggered (DT-A), or ventilator-triggered (DT-V). OBJECTIVE To differentiate DT-P, DT-A, and DT-V using airway pressure or flow...

and Applied Analysis 3 Definition 2.2 see 6 . A subset S of a BCI-algebra X is called subalgebra of X if x ∗ y ∈ S whenever x, y ∈ S. For a BCI-algebra X, we denote x ∧ y y ∗ y ∗ x for all x, y ∈ X 6 . For more details we refer to 3, 5, 6 . 3. t-Derivations in a BCI-Algebra/p-Semisimple BCI-Algebra The following definitions introduce the notion of t-derivation for a BCI-algebra. Definition 3.1....

background routine screening for distress is internationally recommended as a necessary standard for good cancer care given its high prevalence and negative consequences on quality of life. this study attempts to support validation of distress thermometer (dt) in shiraz, iran and in the second step to investigate privilege/priority of dt over other referent criterion measures. material and meth...

BACKGROUND AND PURPOSE While there have been recent reports of brain retention of gadolinium following gadolinium-based contrast agent administration in adults, a retrospective series of pediatric patients has not previously been reported, to our knowledge. We investigated the relationship between the number of prior gadolinium-based contrast agent doses and increasing T1 signal in the dentate ...

Nephrogenic systemic fibrosis is a progressive, potentially fatal multiorgan system fibrosing disease related to exposure of patients with renal failure to the gadolinium-based contrast agents used in magnetic resonance imaging. Because of this relationship between nephrogenic systemic fibrosis and gadolinium-based contrast agents, the U.S. Food and Drug Administration currently warns against u...

OBJECTIVE Arterial spin-labelling (ASL) MRI uses intrinsic blood water to quantify the cerebral blood flow (CBF), removing the need for the injection of a gadolinium-based contrast agent used for conventional perfusion imaging such as dynamic susceptibility contrast (DSC). Owing to the non-invasive nature of the technique, ASL is an attractive option for use in paediatric patients. This work co...
