In matters involving permitting, litigation, or remediation of impacted groundwater, knowing more is way better than knowing less. At Dragun Corporation, we use a multi-technique approach to characterize groundwater and groundwater contamination to develop a more robust and precise site characterization to answer tough questions, withstand rigorous expert review, and/or optimize remediation.
Iconic singer Aretha Franklin had it all: respect, talent, fame and fortune, but what she didn't have was a prepared estate. Reports indicate that the Queen of Soul didn't have a will or trust set up before her death from cancer in August. Now her fortune might be in limbo for her survivors.
A mine site's two largest operational costs are vehicle fuel and tires. Tire longevity is improved by limiting tire temperatures to the manufactures guidelines by limiting the tire's combination of speed, load, and inflation.
The 18650 cell has become the workhorse of the lithium ion battery industry and is a good candidate for analysis of most lithium ion batteries properties. Tesla automobiles, laptop computers, e-cigarettes, scooters, and grid energy storage all use the 18650. The 18650 cell is a leader in cost reduction, stored energy has been continually increasing and over 2 billion cells were manufactured in 2016. Lithium ion cells are truly a marvel of chemistry and electrical engineering.
Discovering end-to-end request-processing paths is crucial in many modern IT environments for reasons varying from debugging and bottleneck analysis to billing and auditing. Existing solutions for this problem fall into two broad categories: statistical inference and intrusive instrumentation. The statistical approaches infer request-processing paths in a "most likely" way and their accuracy degrades as the workload increases. The instrumentation approaches can be accurate, but they are system dependent as they require knowledge (and often source code) of the application as well as time and effort from skilled programmers.
Schools, including public, private, and charter K-12 schools, and colleges and universities, have a responsibility to protect students from physical and emotional harm. Harm that creates a climate of fear can interfere with a student's education, leading to a range of outcomes from failing courses to, in the worst case, suicide. Properly identifying, investigating, and handling school bullying, harassment, and intimidation claims can help school administrators protect children and avoid costly litigation.
Hazard recognition plays a vital role in keeping employees safe. Some hazards are easily recognized, for example an employee climbing up a 20-ft ladder while holding tools in both hands is an obvious fall hazard. While some safety hazards are immediately recognizable, others require training to spot and avoid. One such hazard is hydrogen sulfide (H2S). Training is a key method to avoid the "ostrich zone." You do not want to bury your head when facing this hazard.
Many in the recreational boating public are not aware of a serious type of accident that is neither rare nor without serious consequences. In these incidents the large outboard engine on a fast-moving boat strikes an underwater or floating object, breaks off the boat and flips into the passenger area while still running. The potential for disaster is obvious.
Think you've done everything a prudent person should do to make sure your workers are safe? Think you've done everything necessary to protect yourself and your company against a wrongful death suit? Well, I've got news for you, it's not good and here's why
Welcome to the third and final post in our multipart series of blog posts about a young boy's fall and serious injury at a public playground. In our first post we gave a brief overview of the incident and our investigation. In the second post we discussed some of the safety standards applicable to public playgrounds. In this post, we will examine some of the impact-absorbing playground surfaces available to protect children at playgrounds from injury. If you would like to read the first two posts, they are available here and here.
