    Analyzing the perception of students regarding administrative support, educational process quality, and institutional management within universities in Romania

    We examine Romanian university students’ perceptions of administrative and institutional support, educational process quality, and institutional management, with a focus on how these dimensions shape overall satisfaction and trust in universities. The study is motivated by persistent challenges in infrastructure, teaching quality, transparency, and student representation in Romanian higher education. We conducted a cross-sectional, quantitative study using an online, self-administered questionnaire completed by N = 6,951 students from bachelor’s, master’s, and doctoral programs across public/private HEIs in all eight development regions of Romania. Analyses included descriptive statistics, Pearson correlations, and linear regression to assess relationships among key constructs; internal consistency was excellent (Cronbach’s α = 0.928). Student satisfaction is significantly associated with the material base, teaching quality, support for research, decision-making transparency, and the quality of administrative services. Notable correlations include: transparency with research support (r = 0.604), transparency with teaching satisfaction (r = 0.565), teaching satisfaction with study-subject relevance (r = 0.532), and material base with transparency (r = 0.589). Administrative services relate to perceptions of the material base (r = 0.489). Only ~22% report high satisfaction with the educational process, and 20.7% indicate the material base needs improvement, despite over half rating it good to very good. Findings indicate that targeted investment in infrastructure, stronger institutional transparency (including participatory governance and consistent communication), and effective student representation are pivotal to improving satisfaction

    Biofouling in reverse and forward osmosis membrane systems

    Global freshwater demand has significantly increased over the past century and continued growth is expected in the coming century. Since more than 97 percent of the water in the world is seawater, desalination technologies have the potential to solve the fresh water crisis. Currently, the most used desalination technology is reverse osmosis, where a semipermeable membrane is used to separate the salt from the water. The driving force of reverse osmosis desalination is hydraulic pressure, which has to be greater than the osmotic pressure of the seawater. Due to the high hydraulic pressure reverse osmosis has a high energy demand. Lately, hybrid desalination systems, e.g. indirect desalination with forward osmosis combined with low pressure reverse osmosis are getting more importance. Forward osmosis is also a membrane based process that uses the osmotic pressure difference as driving force. One of the main advantages of forward osmosis is the limited amount of external energy requirement compared to reverse osmosis. The major problem of membrane desalination process is fouling, the accumulation of unwanted material on the membrane surface, causing performance decline and increase of costs. Several types of fouling can occur in membrane processes, biofouling (microbial biofilm formation), scaling (mineral salt precipitation), organic fouling (deposition of organic macromolecules) and colloidal fouling (deposition of particulate matter). In practice biofouling is considered as the major problem in membrane systems.BT/Environmental Biotechnolog

    Analyzing Climate Change Awareness Campaigns: A Bibliometric Study of Scientific Research

    This study presents a bibliometric analysis of scientific research on climate change awareness campaigns, using data from the Web of Science (WoS) database and the keywords “climate change” and “campaign”. Publications from 1994 to 2024 were examined to identify key trends, author networks, and institutional contributions. Following PRISMA guidelines, 1274 records were initially retrieved; after applying exclusion criteria, 1207 documents were included in the final dataset. The results reveal a steady growth in publication output, especially over the last decade, with dominant contributions from environmental sciences, meteorology and atmospheric research, and science and technology studies. While “campaign” is frequently mentioned, it often serves as a methodological or communicative element within broader climate-related research. The United States, the United Kingdom, and Germany lead in publication volume and influence, with increased contributions from countries in the Global South. The global collaboration map highlights strong international efforts and interdisciplinary integration. Based on these findings, future research should evaluate campaign effectiveness, leverage digital tools, foster cross-regional knowledge exchange, and strengthen the link between scientific evidence and public policy. This study offers a foundation for more inclusive, impactful, and evidence-driven climate change communication strategies
