BACKGROUND This research focused on the effects of low electric current (μE)-assisted sonic agitation of sodium hypochlorite on Enterococcus faecalis infected human root dentin. METHODS Extracted human canine roots were instrumented, sterilized, and experimentally contaminated with E. faecalis. After incubation for 21 days, the presence of the biofilm was confirmed by scanning electron micros...

Abstract Heat input is a key component of welding procedure, which dependent on the several fall voltages composing total voltage loss. As current practice primarily reliant trial and error to determine settings for desired heat input, means understand predict loss interest engineers. Voltage, amperage, arc length measurements using ER4043 1.2 mm at varying were used break down constituents giv...

INTRODUCTION This study sought to assess the effects of amperage (mA) and field of view (FOV) on intracanal metal post artifacts and the diagnostic parameters for detection of vertical root fracture (VRF) in teeth with intracanal posts. METHODS AND MATERIALS In this diagnostic study, 80 human single-canal teeth were evaluated by cone-beam computed tomography (CBCT). Nickel chrome cast posts w...

AIM To assess computed tomography (CT) pulmonary angiography (CTPA) dose and image quality in a large teaching hospital, and subsequently, to optimise the protocol in order to reduce the dose without affecting image quality. MATERIALS AND METHODS Dose-length product (DLP), patient size, and objective quality parameters (contrast-to-noise ratio and signal-to-noise ratio on standardised levels)...

The goal of this study is to measure left ventricular stroke volume (SV) from the brachial artery (BA) using electrical bioimpedance. Doppler-derived SV was used for comparison. Twenty-nine healthy adults were recruited for study. Doppler echocardiographic-derived SV was obtained from the product of distal left ventricular outflow tract cross-sectional area and systolic velocity integral. SV fr...

Heating of chromatographic columns, transfer lines, and other devices is often required in neuroscience research. For example, volatile compounds passing through a capillary column of a gas chromatograph (GC) can be split, with half exiting the instrument through a heated transfer line to an insect antenna or olfactory sensillum for electroantennographic detector (GC-EAD) recordings. The heated...

The use cu electro-convulsive therapy has established itself in psychiatric practice. Opinion varies considerably about the risk of fractured limbs and spines. Accidental electric shocks have caused severe injuries to the spine and limbs, but with electro-convulsive therapy the passage of the current is briefer, the voltage is lower, the amperage is less and the size of the terminals is smaller...

Electrochemical ferrous iron (Fe2+) wastewater treatment is gaining momentum for treating municipal due to its decreasing costs, environmental friendliness and capacity removal of a wide range contaminants. Disinfection by electrocoagulation (Fe-EC) has been occasionally reported in full scale industrial applications, yet controversy remains regarding underlying elimination mechanisms kinetics....

Urban transport systems play a major role in the development of today’s societies, but they require technological changes to reduce their environmental impact. The problem lies level autonomy, which is why electrical energy production are proposed for self-consumption, efficiently feeding accumulators. As provided by photovoltaic installations has lower recharge speeds, conventional with high t...

Background The use of cone beam computed tomography (CBCT) in dentistry has proven to be useful in the diagnosis and treatment planning of several oral and maxillofacial diseases. The quality of the resulting image is dictated by many factors related to the patient, unit, and operator. Materials and methods In this work, two dental CBCT units, namely Scanora 3D and 3D Accuitomo 80, were assesse...
