This study explores the perception and knowledge of environmental problems among students of Atatürk University, Turkey, as a developing country, by comparing their perceptions with known facts about environmental problems at local, national, and global levels. In addition, the correlation between the student groups and their knowledge levels and the differences between the student groups according to their knowledge levels when taking age and gender into account are explored. To this end, the research designed as a case study and pursued an exploratory approach revealed that major perceived environmental problems show differences at local, national, and global levels; that consensus on both major perceived problems and knowledge decreases from a local to global level; that a weak correlation exists between the age (r (205) = -.010; .002; -.071) and gender groups (r (205) = -.099; -.125; .065) in terms of their knowledge at local, national, and global level, respectively; and that the contribution of knowledge at a national level can help to explain differences among the age groups (-.304; .102; -.148) at national level and the gender groups (.131; -.205) at national and global levels.

In recent years, image processing technology has been increasingly studied on intelligent unmanned platforms, and the differences in the shooting environment during tobacco baking pose challenges to image processing algorithms. To address this problem, an ensemble multi-dimensional randomization network (EMRNet) for intelligent recognition of tobacco baking stage is proposed. The first is to obtain the tobacco leaf area during the baking process.

Sleep is essential for brain development and overall health, particularly in children with neurodevelopmental disorders (NDDs). Sleep disruptions can considerably impact brain structure and function, leading to dysfunction of neurotransmitter systems, metabolism, hormonal balance and inflammatory processes, potentially contributing to the pathophysiology of NDDs. This Review examines the prevalence, types and mechanisms of sleep disturbances in children with NDDs, including autism spectrum disorder, attention-deficit hyperactivity disorder and various genetic syndromes.

The medical and cosmetic industries have developed in recent years, there has been a growing demand for new materials. Gold nanoparticles (Au NPs) and chitosan (CS) have been known and used for many years. Unfortunately, despite their numerous advantages and possible applications, such materials may possess certain disadvantages and limitations that constitute a problem in medical or cosmetic applications.

Hydrothermal treatment is a physical modification technology to alter starch structures for the production of resistant starch (RS). However, the underlying regulation mechanism of the multiscale structure and digestive properties of starch by dual hydrothermal synergistic treatment remains unclear. To solve this problem, A- and B-type wheat starch granules (AWS and BWS) were separated and subjected to toughening and heat-moisture synergistic treatment (THT) with various moisture content (10 %, 15 %, 20 %, 25 %).

Food security issues are becoming more pressing due to the world's rapid population expansion and climate change, which also drive up demand for nutrient-dense commodities like meat and cereals. Conventional agricultural practices, which depend on pesticides, fertilizers, and antibiotics, are exacerbating environmental problems, such as antibiotic resistance. Precision fermentation has become a game-changing technique that uses microorganisms to create high-value food ingredients more efficiently and with less negative environmental impact.
