Methods: We measured bone Pb concentrations in vivo using portable XRF and KXRF, each measured at the mid-tibia bone in 71 people, 38-95 years of age (mean SD = 63 11 years) living in or near three Indiana communities, US; 10 participants were occupationally exposed. We estimated the correlation between bone Pb concentrations measured by both devices. We also examined the extent to which the detection limit (DL) of the portable XRF was influenced by scan time and overlying soft tissue thickness. Finally, we quantified the associations of estimated bone Pb concentration with age and age with soft tissue thickness.
Results: The mean bone Pb concentration measured via portable XRF was 12.3 16.7 mg Pb/kg dry bone. The uncertainty of a 3-minute (N = 60) in vivo portable XRF measurement ranged from 1.8 to 6.3 mg/kg, in the context of soft tissue thickness ranging from 2 to 6 mm. This uncertainty was reduced by a factor of 1.4 with 5-minute measurements (N = 11). Bone Pb measurements via portable XRF and KXRF were significantly correlated: r = 0.48 for all participants, and r = 0.73 among participants with soft tissue thickness

Conclusion: With its ease of use, portability, and comparable sensitivity with conventional KXRF systems, the portable XRF could be a valuable tool for non-invasive quantification of bone Pb in vivo, especially for people with thinner soft tissue.
Scientists have a portable Vitals monitor that allows them to view the Vitals interface from anywhere on the map, including maps that otherwise do not have a stationary Vitals monitor, such as The Skeld and MIRA HQ. The portable Vitals monitor has a battery that drains upon use but recharges as the Scientist completes tasks or automatically recharges if they have completed all of their tasks.
For players who already have Among Us on their phones and/or PCs, they might not be as interested in getting yet another version - unless everyone in their home wants to play Among Us at the same time, that is. Thankfully, Among Us on Switch costs $4.99 USD - the same price as it does on PC. This means buying a copy of Among Us to have on a portable device like a Switch, as well as purchasing it on PC, is still cheaper than buying most other video games - many of which off much less replayability than Among Us does.
Portable generators provide power to tools and appliances when you need supplemental electricity. They run on gasoline, diesel, or propane and are typically equipped with at least two electrical outlets. Because their combustion engines emit fumes, portable generators should only be used outdoors and at a safe distance from living spaces, although extension cords can be used to carry the power indoors.
While a power outage keeps most people in the dark, it can completely strand electric car owners. If you depend on an electric car to get around, having a portable generator will ensure that you can drive to work, go to the grocery store, pick up the babysitter, rush to the emergency room, or travel wherever else you need to go, even during an extended blackout.
In areas where flooding is an issue, basements often have sump pumps that pump away unwanted water before it can accumulate and cause damage. Heavy rains are the worst possible times for sump pumps to stop working, and unfortunately, power outages often occur during thunderstorms. When you plug the sump pump into a portable generator, you gain the peace of mind of knowing your basement will stay dry even though the power is out.
A key part of the cappuccino is the milk; a key part of the milk is the foam. Foam is what separates a cappuccino from a latte; while the foam-to-milk ratios vary from place to place, even among top-tier venues, a point of agreement is that a cappuccino is mostly foam; a latte is mostly milk.
Gear guru took another look at the portable shower itself and decided he could come up with better idea for RV camping where we have more space to carry stuff. He bought a sprayer unit for less than $20 from a hardware store. It has a wide mouth for ease of pouring in hot water. The pump, hose and nozzle are already in place.
MAXbarbell sells a freestanding portable pull bar unit built by Trapeze Rigging. The goal of this post is to give some advice about when it would make sense to use a freestanding portable pull up bar instead of some of the other types of bars available on the market.
1. It is appealing to have the ability to pack and reassemble your pull-up bar anywhere you work out. With the pull-up unit you can take it to the park, beach, office or swimming pool. The portable pull-up bar can be packed in a bag and only weighs 22lbs; this means you can even take it on a plane.
6. When you need something you can put away and reassemble in under a minute, our pull-up bar is perfect. Also (sad but true), many pieces of home exercise equipment get used a few times, collect dust, then get thrown to the curb. We truly hope that nothing you buy from MAXbarbell.com suffers this fate. In any case, the Trapeze Rigging freestanding portable pullup bar makes a great coat hanger.
Unfortunately for the more adventurous photographers among us, most lighting equipment was not made for hanging over rushing rivers or balancing on rocks, but Zach Gray shows us how to get the job done with a minimum of sketchiness:
But not all golfers tee off in foursomes, which is to say that not everybody needs the quantity of coffee provided in a typical serving from a drip or pour-over coffee maker. For those among us who prefer to tee it up solo, Good Walk has a new line built with you in mind.
As a crewmate, you must perform distracting tasks on a ship (like wiring an electrical panel) while avoiding getting killed by one or more imposters among the crew. Along the way, the crew might determine who the imposter is and eject them into space by popular vote.
The most effective ways to improve your indoor air are to reduce or remove the sources of pollutants and to ventilate with clean outdoor air. In addition, research shows that filtration can be an effective supplement to source control and ventilation. Using a portable air cleaner and/or upgrading the air filter in your furnace or central heating, ventilation, and air-conditioning (HVAC) system can help to improve indoor air quality. Portable air cleaners, also known as air purifiers or air sanitizers, are designed to filter the air in a single room or area. Central furnace or HVAC filters are designed to filter air throughout a home. Portable air cleaners and HVAC filters can reduce indoor air pollution; however, they cannot remove all pollutants from the air. 2ff7e9595c
