Coupling infrared gas analysis & cavity ring down spectroscopy

For autonomous, high-temporal-resolution measurements of DIC and ?13C–DIC

Biogeosciences, 14, 1305-1313, 2017Biogeosciences, 14, 1305-1313, 2017 | http://www.biogeosciences.net/14/1305/2017/

Abstract. A new approach to autonomously determine concentrations of dissolved inorganic carbon (DIC) and its carbon stable isotope ratio (?13C–DIC) at high temporal resolution is presented.

The simple method requires no customised design. Instead it uses two commercially available instruments currently used in aquatic carbon research. Continue reading

FDA warns Thermogram Assessment Services

Over Unapproved Marketing Claims

FDA LetterheadOnline — The FDA recently released a warning letter it sent to Thermogram Assessment Services over a lack of federal clearance or approval for devices it markets.

The agency identified the Palos Verdes, Calif.-based company’s Spatial Thermographic Imaging and Integrated Thermography Systems, as well as its infrared cameras as devices intended for use in diagnosing diseases or other conditions or for use in curing, mitigation, treatment or prevention of disease without the appropriate clearance.

How to Choose a Temperature Data Logger for Vaccine Storage

By CAS admin

Vaccine temperaturesOnline  —  Vaccine temperature data loggers are a cost-effective way to stay in compliance with CDC recommendations concerning proper vaccine storage.

The CDC’s 2016 Vaccine Storage and Handling Toolkit states that the surest way to avoid losing valuable vaccine supplies is to use a temperature monitoring system for every medical storage unit in your facility. Continue reading

Horrific Air Pollution in Europe & Asia

Europe Reaches 7 cigarettes per day equivalent, a pack a day in India & China

Screen Shot-BE_AP_EuropeOnline  —  It’s winter, and that’s the worst air pollution period for Europe and China. The levels over much of the continent are in the unhealthy range.

In the figure we show a map of the pollution of particulate matter in Europe, “PM[2.5]”, the most lethal of the common air pollutions.

The map was taken from our website: http://berkeleyearth.org/air-quality-real-time-map/, where it is updated hourly. Continue reading

Non-contact infrared thermometers for measuring body temperature in acutely ill children: a method comparison study

Nonthermofocus-contact infrared thermometers for measuring body temperature in acutely ill children: a method comparison study. Health Technology Assessment

Authors’ objectives

Fever in young children is very common, and doctors measure a child’s temperature to help them decide whether the child can be kept at home or needs to go in to hospital. National guidelines recommend measuring temperature whenever a child is ill using a digital thermometer in the armpit or an infrared thermometer in the ear.

However, both of these types of thermometers can be difficult to use in unwell children who are not cooperating with the doctor.

A new type of thermometer, the non-contact infrared thermometer, can measure temperature very quickly without touching the child. However, a recent review found that at present there is not enough research evidence to recommend their widespread use.

In this study we aim to assess whether non-contact thermometers are as good at measuring temperature as digital armpit or infrared ear thermometers.

We will also compare their ability to detect a fever and the number of times they fail to work (either because the child won’t cooperate or the device doesn’t work) with these standard types.

We will ask parents and children what they think about the different types of thermometers, and interview some parents in more detail about this. We will see whether non-contact thermometers produce similar results when the measurement is repeated in the same child.

Since some non-contact thermometers are much more expensive than others, we will assess two brands:Read ore at the link below.
