The primary objective of this study was to determine sharps disposal practices among people with diabetes in a community care clinic. Secondary objectives were to identify patterns of sharps use and ...barriers to proper use.
Surveys were distributed to patients at a community care clinic in person and via mail. Survey questions focused on how sharps are used and disposed of, the frequency of sharps changes, sharps disposal training, sharps identification, and confidence in sharps disposal. Participant demographics and diabetes profiles were also collected.
Among 89 respondents, mean age was 60 years (range 29-93 years), 61.8% were Caucasian, 88.8% had type 2 diabetes, and 60.7% had had a diabetes diagnosis for ≤10 years, with diverse diabetes management methods; 57.3% did not receive or were unsure of sharps training, 25.8% discarded used sharps without a designated sharps container, and 37.1% properly disposed of sharps containers at sharps disposal facilities. Barriers to proper sharps practices included perceived safety of reusing sharps and waste with single use, cost, and the hassle of disposal. Those with prior sharps training were more likely to properly use and discard sharps; however, gaps in knowledge were still evident in this population.
Results indicate gaps in proper sharps use and disposal knowledge among people with diabetes. Responses revealed sharps practices that are inconsistent with current federal and state regulations and are potentially dangerous for those handling improperly discarded sharps. Targeted sharps usage and disposal education resources are needed for individuals with and without prior sharps training.
In this study, carbon fiber reinforced polymer (CFRP) was connected to either a stainless steel or titanium screw and then placed in a salt water solution, with measurements being taken using a ...potentiostatic electrochemical impedance spectroscopy (PEIS) system to determine each system’s impedance values at varying frequencies. The collected numerical data was then used to determine the number of interfaces within each sample via a modeling program in the PEIS system that used Randles Circuits (RC) in series. Samples were also examined using a scanning electron microscope (SEM) and an energy-dispersive X-ray spectroscopy (EDS) system to determine if any products of the metallic corrosion had caused any mechanical damage to the CFRP. It was noted that the titanium exhibited stable impedance values over the course of the experiment while also not causing any damage to the CFRP structure. The stainless steel on the other hand exhibited more erratic impedance values of the course of the study while also showing apparent damage to the surface of the CFRP to which it was connected in the form of delamination.

Media multitasking entails simultaneously engaging in multiple tasks when at least one of the tasks involves media (e.g., online activities and streaming videos). Across two studies, we investigated ...one potential trigger of media multitasking, state boredom, and its relation to media multitasking. To this end, we manipulated participants' levels of state boredom using video mood inductions prior to administering an attention-demanding 2-back task during which participants could media multitask by playing a task-irrelevant video. We also examined whether trait boredom proneness was associated media multitasking. We found no direct evidence that state boredom leads to media multitasking. However, trait boredom proneness correlated with greater amounts of media multitasking in Experiment 1, but not in Experiment 2. Surprisingly, in both experiments, post-task ratings of state boredom were equivalent across conditions, alerting us to the short-lived effects of video mood inductions and the boring nature of cognitive tasks.
Evidence suggests that one's likelihood of media multitasking increases with time-on-task, which can negatively impact performance. The opportunity costs account of sustained attention might explain ...this finding. This account states that rising feelings of boredom and effort signal increasing opportunity costs, motivating us to direct our attention elsewhere and causing progressive decreases in performance. We examined whether patterns of media multitasking, boredom, effort and performance during a sustained attention task supported the notion that rising opportunity costs drive temporal increases in media multitasking. We further tested this account by affording one group of participants the option to respond to increasing opportunity costs by watching a video (media multitasking) while completing the task. Another group received no such option. Temporal patterns of media multitasking, boredom, effort and performance partially supported the opportunity costs view. Surprisingly, many also multitasked with activities outside the experimental context. Exploratory analyses revealed that patterns of boredom, effort and performance among these individuals and those who did not multitask supported the opportunity costs view. Our findings suggest that many media multitask in response to rising opportunity costs signaled by changes in feelings of boredom and effort - a relation that may be particularly problematic for online studies.
The precision length calibration process is very much like any length measurement process, but taken to a significantly higher level. Both processes are composed of the same elements. In this ...article, the following five key parts of any measurement/calibration process are presented.

Screw threads are one of those important elements of mechanical design that are often taken for granted but find usage in critically important applications. There is a very complex science behind ...applications of threads--even thinking about it can send shivers down the spine of the most astute mechanical engineer. The large spread of applications requiring threaded parts come with such a variety of performance requirements that one can get lost in some of the principle design functions such as how a threaded part is assembled to a matching part, how a threaded part performs under different operating conditions, and the strength of the threaded components. On a straight threaded plug gage, the two most common checks that need to be certified are the plug gage major diameter and the pitch diameter. As with other dimensional standards, there are industry standards that define how thread standards must be calibrated. In this case, ASME B1.3 is the one to reference.
