Law enforcement officers in the field encounter a vast number of confusing street drugs, and administrators looking to purchase portable drug testing technology may find the choices equally confusing. A new landscape report from the Forensic Technology Center of Excellence (FTCoE), Landscape Study of Field Portable Devices for Presumptive Drug Testing, can help clear up that confusion.

Grabenauer notes that from a strict legal perspective, some NPSs are not unlawful, and being able to use a portable device to determine something is not a controlled substance is an important feature. Many devices come with a library that is revised on a regular basis through firmware updates or Internet downloads, a key way of keeping tabs on emerging NPSs. This leads to another advantage portable field devices have over traditional color-based testing, because no one knows how those tests would react with one of the new materials.
Another significant difference between the portable devices and color-based testing is cost, with pricing on the miniaturized versions of lab instruments starting at around $25,000 and going up from there. (Traditional color-based test kits cost relatively little.)

Conclusions regarding bite count rates and body mass index (BMI) in free-living populations have primarily relied on self-report. The objective of this exploratory study was to compare the relationship between BMI and bite counts measured by a portable sensor called the Bite Counter in free-living populations and participants eating in residence.
Feedback data on body weight and total daily intake has been used to successfully modify weight behavior [1]. However, these apps do not including timing and speed of eating behavior. Recently developed portable sensors that detect and provide real time ecologically valid data on eating behavior provide for the first time insight in free-living settings and detect whether results previously obtained in the laboratory or cafeteria setting translate to a free-living environment [2]. To date, eating rate measurements have required in clinic supervised eating, which limits participant sample size and observation of behaviors in a free-living environment. On the other hand, free-living measures of eating rates have long relied on self-report, which has not been demonstrated reliable [3].
Our study has several limitations. The first limitation of the bite counter is that it cannot estimate bite size. Thus, individuals who eat longer may be ingesting smaller food mass per bite, which cannot be calculated by current methods. This ultimately limits the bite counter for deriving cumulative eating curves [19] which aggregate almost the entire set of eating behavior variables (speed, mass, and length) [20]. However, the bite counter applied with doubly labeled water to determine total energy intake per day offers an interesting avenue for triangulating intake data in free-living individuals and providing insights into eating behavior not previously accessible. Also, the bite counter must be turned on and off when the meal begins and ends. This presents a unique challenge and we note that at best the bite-counter represents a lower bound of eating duration. Nonetheless, it does provide objective evidence which perhaps could be combined with self-report and model tracking like those used in smart phone applications [21].
In the context of this study, it does not appear that obese subjects on average have faster bite count rates than normal weight individuals. In fact, in both samples bite count rate was inversely associated with BMI. Individuals with a higher BMI ate longer than their lean counterparts. With additional novel applications of the bite counter, insights into free-living eating behavior may provide avenues for future interventions that are sustainable for long term application.
Vanlandingham said that using portable ultrasound technology allows ER doctors to get a better look at certain types of trauma more rapidly than other methods, which could mean the difference between life or death.
Due to the increased complexity of modern day piloting which demands the ability to handle large ships safely and efficiently, it is becoming more common for pilots to bring their own portable navigation systems onboard with them.
Portable chest X-rays are the most common diagnostic exam in intensive care units. Having the ability to perform them at the bedside is extremely valuable, as there exists clear clinical evidence that the latest digital radiography (DR) detector portable X-ray units allow for portable exams to be performed in almost half the time previously required for computed radiography (CR) and film-based exams.
Smaller panels are most often utilized in NICUs and for orthopedic imaging of extremities, while larger panels are used for most other portable X-ray exams, such as studies of the chest, hips, and abdomen.
Although analog portable X-ray units require a modest investment, $40,000 to $80,000, as compared with their digital cousins, advances in flat panel detector technology have made digital systems coupled with flat panels the gold standard in most U.S. hospitals today. Hospitals with an existing analog system have the option to retrofit a detector, which typically costs $62,000 to $140,000 depending on the size and type of flat panel. New fully-digital portable X-ray units run about $125,000 to $235,000 depending on maximum power output options and type of detector selected.
The 2018 Winter Olympics take place from 9th February to 25th February 2018, in Pyeongchang, South Korea. The elected host city was announced by the International Olympic Committee (IOC) in July 2011. Pyeongchang won on its third consecutive bid, having lost previously to Vancouver in Canada and Sochi in Russia. It is the first Winter Olympic Games and second Olympic Games in South Korea; the 1988 Summer Olympics were held in Seoul. Pyeongchang is also the third Asian city to host the Winter Games after Sapporo, Japan (1972) and Nagano, Japan (1998). It is the first Winter Olympic Games since 1992 to be held in a ski resort town. In June 2015, four new disciplines were approved for inclusion in the games: snowboarding big air; curling mixed doubles; speed skating mass start and Alpine skiing team.

The 2018 FIFA World Cup is held in Russia from 14th June to 15th July 2018. This is the first time that Russia has hosted the World Cup. Some $10 billion is spent on the tournament, which is spread over 14 venues including Moscow and St. Petersburg. As of 2010, there were no stadia in the country with 80,000+ capacities, but Luzhniki Stadium in Moscow is expanded to 90,000 seats in time for the games. France beat Croatia in the final, winning 4-2.
With its sub-surface measurements and hyper-sensitive instruments, Insight greatly improves our understanding of differentiation. The mission confirms whether Mars' core is solid or liquid, and determines why the crust is not divided into tectonic plates that drift like on Earth.* Following a technical issue reported in December 2015, the probe's launch was postponed from March 2016 to May 2018. It touches down on Mars on 26th November 2018.*
The 100,000 Genomes Project is a 300 million (US$467m) effort to sequence the genomes of National Health Service (NHS) patients in England. It was first announced in 2012, with the project expected to run until late 2018.* By utilising such a large sample size, it was hoped that common genetic traits behind a number of cancers and rare diseases could be identified, paving the way for new diagnostic tools, drugs and other treatments.
Current classroom observation strategies include questionnaires, interviews, tests, self-report metrics and live or video review observation. However, these traditional methods are subject to biases from observers in determining behavior nuances, as well as being difficult to analyze for rapid and practical feedback. In addition, the invasiveness of extra body equipment in the classroom may alter the dynamic between students and teachers. The emergence of portable devices into mainstream usage has opened a pathway for a relatively novel source of quantitative data, free from observer bias and often with accompanying analytical tools for convenience. The purpose of this study is to summarize current uses of portable technology and explore how such devices could be used as monitoring tools by both schools and education researchers.
While current portable technology is unlikely to replace more commonly used techniques of observing classes, they have the capacity to augment qualitative strategies, particularly in the area of real-time data output.
