Monitoring for leak hazards is an important consideration in the deployment of carbon dioxide geologic sequestration. Failure to detect and correct leaks may invalidate any potential emissions benefits intended by such projects. Presented is a review of remote sensing methods primed to serve a central role in any monitoring program due to their minimally invasive nature and potential for large ...

Melanic pigmentation results from melanin produced by the melanocytes present in the basal layer of the oral epithelium. One of the most common causes of oral pigmentation is smoker melanosis, a condition associated with the melanocyte stimulation caused by cigarette smoke. This paper aims to illustrate the use of a carbon dioxide laser in the removal of the gingival melanic pigmentation for ae...

UNLABELLED BACKGROUND OF OBJECTIVE: Treatment of xanthelasma palpebrarum may prove difficult due to its delicate location at the periorbita and its sometimes extensive dimension. During recent years, carbon dioxide and argon lasers have been used with good results. However, local anesthesia is always required, and there is a concrete risk of scarring and pigmentation changes after the treatment...

An experimental method is presented for characterization of the combined intensity and frequency modulation produced when the injection current of a laser diode is modulated. The reported technique is based on the analysis of the harmonic signals produced when a modulated laser is used to probe a gas absorption line by the so-called wavelength-modulation spectroscopy method. Based on a theoreti...

to evaluate the effects of various concentration of carbon dioxide and salinity stress on morphophysiological characteristics of amaranthus tricolor l. an experiment was conducted in greenhouse conditions in faculity of agriculture ferdowsi university of mashhad. the experiment was split plot based on completely randomized design with three levels of co2 (380, 700, 1050 µl/l) and three concentr...

The objective of this study is to conduct a systematic review the literatures on effect treatment combining 9300 nm carbon dioxide (CO2) lasers and fluoride prevention enamel caries. A literature search was performed using PubMed, Scopus, Web Science. keywords were ((9300 nm) OR (9.3 µm) (carbon laser) lasers) (CO2 lasers)) AND ((fluoride) (fluorides)) ((dental caries) (caries) (remineralizatio...

Introduction: The use of lasers for treatment has become a common phenomenon in the medical field. Currently, numerous laser systems are available for dental use. The use of lasers for periodontal treatment becomes more complicated because the periodontium consists of both hard and soft tissues. Methods: Related articles were gathered and selected carefully and reviewed. Among the many lasers a...

An overview of several innovations regarding in situ laser-heating techniques in the diamond anvil cell at the high-pressure beamline ID27 of the European Synchrotron Radiation Facility is presented. Pyrometry measurements have been adapted to allow simultaneous double-sided temperature measurements with the installation of two additional online laser systems: a CO2 and a pulsed Nd:YAG laser sy...
