Production of Activated Carbons from Food/Storage Waste.

This paper deals with the adsorption of organic and inorganic pollutants on the surface of carbonaceous adsorbents prepared via the chemical activation of expired or broken food products-the solid residue of the "cola-type" drink as well as spoilt grains of white rice and buckwheat groats. The activation process was conducted in the microwave furnace with the use of two activating agents of different chemical nature-potassium carbonate and orthophosphoric acid. The activated carbons were characterized based on the results of elemental analysis, low-temperature nitrogen adsorption/desorption, Boehm titration, thermal analysis, and scanning electron microscopy. Additionally, the suitability of the materials prepared as the adsorbents of methylene blue and iodine from the aqueous solutions was estimated. The materials obtained via chemical activation with H3PO4 turned out to be much more effective in terms of both model pollutant adsorptions. The maximum sorption capacity toward iodine (1180 mg/g) was found for the white-rice-based activated carbon, whereas the most effective in the methylene blue removal (221.3 mg/g) was the sample obtained from the solid residue of the expired "cola-type" drink. For all carbonaceous materials, a better fit for the experimental adsorption data was obtained with the Langmuir isotherm model than the Freundlich one.

Female Sex and Living in a Large City Moderate the Relationships between Nursing Students' Stress Level, Perception of Their Studies, and Intention to Practice Professionally: A Cross-Sectional Study.

One way to increase nursing retention is to expand the number of nursing education programs; however, a more cost-effective initial step would be to ensure that each graduate will start a professional career. Nursing studies expose students to prolonged and uncontrolled stress that negatively affects their professional identity and health. Two hundred and fifty-four nursing students participated in this study. The data were obtained using the Perceived Stress Scale (PSS-10), a proprietary questionnaire on the students' perception of their study, intention to practice in the future, and other metrics. Among our sample, a dozen students were unsure that they would enter the nursing profession. Stress levels in women were higher than in men. Respondents indicated that they were afraid of the return of the pandemic. This analysis was significant among people living in large cities. Based on our findings, five themes should be prioritised: favourable study environment and adequate competencies (including implementation of stress management techniques, especially among women and students living and studying in large cities), appropriate working hours, quality of practical classes, and quality of personal protective equipment.

Novice nurses' readiness to practice in an ICU: A qualitative study.

BACKGROUND: Novice nurses (newly qualified within the first 3-year period of professional practice after registration) must first face the reality and complexity of caring for high-acuity patients in the critical care setting, which can be an unfamiliar and demanding environment. The successful transition from education to professional practice of novice nurses hired for intensive care must be supported. AIM: To explore Polish novice nurses' readiness to practice in an intensive care unit (ICU). Our study objectives included investigating pre-registration preparation for work in an ICU, identifying the most needed competencies to work in an ICU, and analysing organizational aspects of the professional orientation period. STUDY DESIGN: A qualitative phenomenology design was applied. METHODS: We conducted qualitative content analysis based on individual semi-structured in-depth interviews. Study recruitment was performed using a purposeful and network sampling strategy. The final number of participants was 17 Polish novice nurses. RESULTS: The majority of responders replied that they were not prepared to work in an ICU after graduation. Professional orientation was planned-generally for a period of 3 months; however, in most places it was shortened. The respondents identified the five competencies most needed to work in an ICU: communication, teamwork, professional self-confidence, and knowledge and its practical use. Their enhancement could be achieved through simulations during both pre-registration and professional training. CONCLUSION: Analysis of the novice nurses' orientation period revealed many difficulties that indicated a lack of readiness to practice in an ICU after graduation. Identifying novice nurses' strengths and weaknesses regarding clinical competence is important to guide the design of orientation programmes in ICU settings and nursing education programmes. RELEVANCE TO CLINICAL PRACTICE: Readiness for ICU work may be improved by enriching education with simulations that enable training in the practical use of knowledge and critical care procedures. A supportive work environment is crucial during professional orientation.
