Modern Era

Plastic waste represents one of the largest environmental problems of the modern era and disposable water bottles comprise a substantial portion of that waste in the U.S. Colleges are in a unique position to create systems that foster sustainable behaviors among their constituents. Since 2015, Allegheny College has installed water refill stations, and initiated a free water bottle program and an awareness campaign to reduce single-use bottles on the college’s campus. Two surveys were distributed to the student body between 2018 and 2019 to assess the efficacy of those initiatives and learn about any barriers. Bottled water use has reduced significantly since 2014, with the majority of students stating that they most commonly drink water from refill stations while on campus. Demographic factors like income, sex, or place of origin were not related to the amount of bottled water consumption or type of water preference among students. The primary barrier to students eliminating disposable water bottle use was found to be a lack of water refill stations in dormitories. Research aimed at changing behaviors to benefit the environment should consider the barrier of convenience. This research provides a valuable lesson that can extend beyond college campuses and into public settings.

Harmful Effects

Bottled water is one sector of the beverage industry that has recently experienced substantial growth. The littering of plastic water bottles and the carbon emissions produced from bottled water production results in harmful effects on the environment. To reduce the harm of bottled water production and litter, government and non-government organisations have implemented litter abatement and behavioural change strategies targeting bottled water consumption and subsequent loss of bottles to the environment. Our study evaluated the success of one of these strategies, which is a filtered water refill station, implemented along the Brisbane River in Queensland, Australia. We found plastic bottle litter decreased after a water refill station was put into operation. However, given the location of the refill station, we suggest the behavioural change strategy employed did not reach its full potential. We highlight factors that could be employed to achieve maximum benefits when implementing similar behavioural change strategies.

The Impact

The plastic bottles that are used for packaging water are harmful to the environment. The objective of this study was to examine the influence of consumers’ environmental concern on both their intention to reduce consumption of water sold in single-use plastic bottles and their actual behaviour. An extended version of the theory of planned behaviour is used as the main theoretical framework. Structural equation modelling is employed based on data gathered in 2020 from 1011 Polish respondents to test the study’s hypotheses. The results support the model, as all tested relations are statistically significant. More specifically, we confirm the indirect impact of environmental concern on both intention and behaviour concerning bottled water consumption (BWC): environmental concern is positively related to attitudes towards reducing BWC, subjective norms regarding reduction in BWC, perceived behavioural control over BWC, and perceived moral obligation to protect natural resources, all of which, in turn, are positively related to intention to reduce BWC. We also prove that intention to reduce BWC is positively related to consumption of non-bottled water. The results may serve to guide decision makers seeking to promote ecologically friendly behaviour.

Considerable Damage

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.
