Responsibility as an Ethics and Sustainability Element during the Pandemic.

This article addresses two perspectives of responsibility: as an element of taking action and as ethics towards one's fellow citizens and the environment. These aspects have been used since the beginning of the pandemic. In this context, we wanted to determine the mechanism that triggers increased responsibility. We have considered two possible initial processes: one external and one learned from the family in early childhood or trained/learned during studies. Based on that, three concerns were brought to our attention. First, we targeted the impact of the pandemic on respondents' degree of responsibility for their livelihoods. Second, we wanted to determine to what extent the new situation increased the interviewee's involvement only in some activities. The third statement called into question the causal relation between the influence of extrinsic elements on a highly educated person's degree of responsibility. The focus group was the active population of the industrial sector in the North-West border area of Romania. The data obtained are the result of the sociological survey implementation. The people in the region were subject to several new limiting external factors. The results show that the unique challenges up to that point made them more accountable for their actions in a situation that affected them directly (pandemic). It also can be underlined that lifelong education is important in forming healthy principles of responsibility.

Analysis of Sustainable Communication Patterns during the Telework Period in Western Romanian Corporations.

The research was conducted in a particular context, the recent pandemic. It is a comparative study of the methods and quality of communication in global companies between 2021 and 2022. The corporations involved in the research are important providers of flexible production, quality, and logistics solutions that cover customers' real needs. They are active in the automotive industry and units involved in mass production in the electronics industry, household appliances, and cosmetics industries. In their case, it was noted that to achieve operational objectives such as developing employee skills, using advanced technologies, and exceeding customer expectations, it is important to use innovative methods and tools such as single platforms, which allow access to the most important information from a distance, anywhere, anytime. It is significant that, according to the research, the preferred method of communication by employees, regardless of the existing conditions, is face-to-face. Primarily, this method is chosen because it provides an open area of interpersonal interaction. The participants observe non-verbal attitudes or can perceive emotions and feelings. Their personality can be identified through unintentional contact to obtain constructive feedback through guidance and counseling. Moreover, it can be formed and develop productive, intentional connections. Stakeholders' efficient and effective open dialogs are encouraged in this sense.

Salvia officinalis L. Essential Oil: Characterization, Antioxidant Properties, and the Effects of Aromatherapy in Adult Patients.

The purpose of this study is to reveal the chemical and biochemical characteristics and the potential aromatherapy applications of the essential oil (EO) of Salvia officinalis (common sage) within a hospital environment. The chemical composition was determined by gas chromatography with mass spectrometry and ATR-FTIR spectroscopy. Three types of sage EOs were included in this study: two commercial oils and one oil obtained by in-house hydrodistillation. Based on the findings, these EOs were included in different chemotypes. The first two samples were similar to the most common chemotype (α-thujone > camphor > 1,8-cineole > ß-thujone), while the in-house sage EO revealed a high content of 1,8-cineole, borneol, α-thujone, similar to the Dalmatian type. The latter sample was selected to be evaluated for its antioxidant and medical effects, as borneol, a bicyclic monoterpene, is known as a substance with anesthetic and analgesic effects in traditional Asian medicine. The study suggests that the antioxidant capacity of the sage EO is modest (33.61% and 84.50% inhibition was determined by DPPH and ABTS assays, respectively), but also that the inhalation of sage EO with high borneol content by hospitalized patients could improve these patients' satisfaction.

Recent Trends in Biosensors for Environmental Quality Monitoring.

The monitoring of environmental pollution requires fast, reliable, cost-effective and small devices. This need explains the recent trends in the development of biosensing devices for pollutant detection. The present review aims to summarize the newest trends regarding the use of biosensors to detect environmental contaminants. Enzyme, whole cell, antibody, aptamer, and DNA-based biosensors and biomimetic sensors are discussed. We summarize their applicability to the detection of various pollutants and mention their constructive characteristics. Several detection principles are used in biosensor design: amperometry, conductometry, luminescence, etc. They differ in terms of rapidity, sensitivity, profitability, and design. Each one is characterized by specific selectivity and detection limits depending on the sensitive element. Mimetic biosensors are slowly gaining attention from researchers and users due to their advantages compared with classical ones. Further studies are necessary for the development of robust biosensing devices that can successfully be used for the detection of pollutants from complex matrices without prior sample preparation.

Closing the Loop with Keratin-Rich Fibrous Materials.

One of the agro-industry's side streams that is widely met is the-keratin rich fibrous material that is becoming a waste product without valorization. Its management as a waste is costly, as the incineration of this type of waste constitutes high environmental concern. Considering these facts, the keratin-rich waste can be considered as a treasure for the producers interested in the valorization of such slowly-biodegradable by-products. As keratin is a protein that needs harsh conditions for its degradation, and that in most of the cases its constitutive amino acids are destroyed, we review new extraction methods that are eco-friendly and cost-effective. The chemical and enzymatic extractions of keratin are compared and the optimization of the extraction conditions at the lab scale is considered. In this study, there are also considered the potential applications of the extracted keratin as well as the reuse of the by-products obtained during the extraction processes.

Removal of Cypermethrin from Water by Using Fucus Spiralis Marine Alga.

Alpha-cypermethrin is a synthetic pyrethroid that was extensively used for insect control, since the early 1980s. However, it is known that its presence in the environment has toxic effects on humans and aquatic life forms. For this reason, it is commendable for it to be removed completely from the contaminated environment. In this study, we evaluated the adsorption capacity of a marine alga for the removal of cypermethrin from water. The adsorption experiments were performed based on the batch equilibrium technique. The samples containing the pesticide were analyzed using gas chromatography with an electron capture detector, after liquid-liquid extraction in hexane. The results obtained from the kinetic adsorption studies showed that the equilibrium time was attained after 40 min. The adsorption parameters at equilibrium concentrations, obtained through the Langmuir, Freundlich, and Temkin models, showed that the used brown marine alga has a maximum amount of adsorbed cypermethrin of 588.24 µg/g. The correlation coefficients obtained for each model prove that the Langmuir model best fits the experimental data.
