BACKGROUND Laptop computers may release nickel and cobalt when they come into contact with skin. Few computer brands have been studied. OBJECTIVES To evaluate nickel and cobalt release from laptop computers belonging to several brands by using spot tests, and to quantify the release from one new computer by using artificial sweat solution. METHODS Nickel and cobalt spot tests were used on t...

As a tendency to use new technologies, gadgets such as laptop computers are becoming more popular among students, teachers, businessmen and office workers. Today laptops are a great tool for education and learning, work and personal multimedia. Millions of men, especially those in the reproductive age, are frequently using their laptop computers on the lap (thigh). Over the past several years, ...

The use of laptop computers is increasing, and many children and young adults spend hours with their laptops on their laps daily. We report a case with erythema ab igne on the thigh of a 17-year-old girl, induced by use of laptop computers four to five hours daily for nine months.

The design, development, testing, and integration methodology for antennas integrated into laptop computers is described. Two key parameters are proposed and discussed for laptop antenna design and evaluation: standing wave ratio (SWR) and average antenna gain. A novel averaging technique was developed and applied to these to yield a measurable, repeatable, and generalized metric. A prototype a...

Computers freezing to work is a common problem and can cause unexpected damages if the work is important but not saved yet. This kind of problems is often caused by software failures which are hard to predict. This paper focuses on the reliability analysis of laptop computers experiencing multiple occurrences of failures in operation. The failure has been defined as the event that the computer ...

Laptop burn is a real condition and medical reports indicate that using a laptop across the legs can indeed cause it. in very rare cases, the condition can cause damage leading to skin cancer. A 24-year-old man presented with an asymptomatic reddish brown pigmentation on the thighs. After an extensive work-up, burning caused by use of a laptop was observed. Burning was induced in 3 days by usin...

One of the goals of introducing computers to the classroom is to support students who are more reluctant to the use of technology or who do not have a computer at home in acquiring computer literacy. Studies have shown that these students are often girls. The goal of the present study is to find out if the difference between boys and girls in computer literacy can be leveled out in a laptop pro...

Students often have their own individual laptop computers in university classes, and researchers debate the potential benefits and drawbacks of laptop use. In the presented research, we used a combination of surveys and in-class observations to study how students use their laptops in an unmonitored and unrestricted class setting—a large lecture-based university class with nearly 3000 enrolled s...
