Plastic pollution requires, among a suite of other interventions, education to inspire behavioral change and reduce consumption of single-use items. We designed and installed an ocean plastics exhibit at the Oregon Coast Aquarium in Newport, Oregon, USA. We evaluated visitor engagement and the effects of the exhibit on their reported single-use plastic and plastic-related environmental stewardship intentions. Timed interaction observations ( n = 317) revealed children (0–17 years) engaged more with interactive elements than adults (18–80+ years). Ten single-use plastic reduction and plastic stewardship intentions were evaluated through structured questionnaires; the top three behaviors visitors intended to change were: using a reusable straw (37.4%), cleaning the beach (37.4%), and bring-your-own bag to the store or market (33.0%). 18 to 29 year olds had the highest change in desire to address the ocean plastics problem before and after seeing the exhibit, but the lowest likelihood of engaging in either single-use plastics reduction or plastic stewardship actions of all age groups.

In carrying out an investigation into the explosion, among others, the investigative version of the use of a single-use reactive grenade launcher is being considered. The most common for criminal explosions are applied grenade launchers RPG-18, RPG-22, RPG-26. Their use is due to a number of such properties as small size and weight, which makes it possible to transfer them covertly, the range of the shot significantly exceeding the range of the hand grenade throw, the high detonating effect of the rocket grenade explosion. The single-use rocket launchers are generally of the same design. Their differences are in the features of the components construction and dimensional characteristics, which are given in the article. On the basis of expert practice, details ofgrenade launchers that remain at the site of the explosion and have the least damage are determined. These details are the objects of investigation of the explosion technical expertise. These objects include launchers of grenade launchers and rocket parts ofjet grenades. The design features of the launchers, their dimensional characteristics and marking symbols make it possible to determine their belonging to a specific type of jet grenade launchers. Missile parts of jet grenades differ in the form of the combustion chamber of the jet engine, nozzle, in the size ofthe outlet section of the nozzle, in the form and size of the stabilizerfeathers. To determine the belonging of the rocket part of the grenade to a specific type ofjet grenade launcher, it’s necessary to establish a set of structural features and dimensional characteristics. At considerable damage of the combustion chamber of the jet engine, as a rule, the nozzle block remains intact that allows to define diameter of critical section of a nozzle, and on it to establish type of the used single-use grenade launcher.

The COVID-19 pandemic, caused by severe acute respiratory syndrome coronavirus 2, has challenged healthcare providers in maintaining the supply of critical personal protective equipment, including single-use respirators and surgical masks. Single-use respirators and surgical masks can reduce risks from the inhalation of airborne particles and microbial contamination. The recent high-volume demand for single-use respirators and surgical masks has resulted in many healthcare facilities considering processing to address critical shortages. The dry heat process of 80°C (176°F) for two hours (120 min) has been confirmed to be an appropriate method for single-use respirator and surgical mask processing.
