Vehicle Pollutant Emissions
The combustion of common petroleum fuels like petrol and diesel in IC engines releases the following major species: nitrogen, water, CO2, O2, NOx, CO, unburned hydrocarbons (VOCs), and PM in the exhaust. Secondary species like SO2, N2O, aldehydes, and ammonia can also be produced. CO2 is a GHG and is thus harmful to the global environment but in the amounts leaving automotive exhaust, it is not harmful to human health directly. Water and nitrogen are benign species. The remaining species (CO, NOx, VOCs, PM, and SO2) are pollutants and have harmful health implications. In addition to these exhaust emissions, non-exhaust emissions (as PM) are also produced by vehicles, most notably from brake, tyre, and road wear, and re-suspension of previously deposited roadside dust.

Effects of Climate Change on Northeastern American Forests
Forests and forestry-related industries and ecosystem services play a critical role in the daily life of all societies, including in cultural, ecological, social, economic, and environmental aspects. Globally, there are about 4.1 billion hectares of forestland. In the United States, there are about 304 million hectares of forestland, covering about 34% of the total land area, and the forest product industry produces over USD 200 billion worth of forestry products annually. Evidence suggests these precious resources may be negatively impacted by climate change via direct and indirect processes, including wildfires, insect/pest pressure, drought, extreme storm events, increased air temperature, solar radiation, vapor pressure deficit, and other factors and variables that can be detrimental.

Methods for Measuring Landslides
Landslides are among the most destructive geo-disasters, causing substantial property damage and safety problems worldwide. Defined as the gravitational movement of mass down a slope, they can result from various events such as severe precipitation, earthquakes, volcanic activity, and human activities.

Seagrass Bed Pollution
Due to climate change and human activities, seagrass is in crisis as the coverage of seagrass declines at an accelerated rate globally. The eutrophication in coastal waters and discharge of pollutants such as sulfide, heavy metals, organic matter and microplastics caused by human activities are important reasons for seagrass loss. In addition, environmental stressors lead to reduced immunity and decreased resistance of seagrass to various pathogens, leading to seagrass wasting diseases.

Large Mammals as Vitamin C Sources for MIS 3 Hominins
The acquisition of large prey by hominins living during the Marine Isotope Stage 3, including Neanderthals and Anatomically Modern Humans, had nutritional and bioenergetic implications: these contain high fat amounts, provide a high energy return, and the strategies and skills required to acquire small prey were different from those required to acquire the former. Vitamin C availability at several MIS 3 periods could have had a strong seasonal variability and would have been decisive for hominin groups’ survival.

Advancing Surface Plasmon Enhanced Fluorescence based POC technologies
Point-of-care (POC) diagnostic platforms are globally employed in modern smart technologies to detect events or changes in the analyte concentration and provide qualitative and quantitative information in biosensing. Surface plasmon-coupled emission (SPCE) technology has emerged as an effective POC diagnostic tool for developing robust biosensing frameworks. The simplicity, robustness and relevance of the technology has attracted researchers in physical, chemical and biological milieu on account of its unique attributes such as high specificity, sensitivity, low background noise, highly polarized, sharply directional, excellent spectral resolution capabilities.

Past Developments of Carpathian Forests
The Carpathians are the second largest mountain range in Europe and provide multiple ecosystem services of enormous regional importance. The Carpathians belong to seven Central and Eastern European countries (Czech Republic, Slovakia, Poland, Hungary, Ukraine, Romania, and Serbia), whose share of forest land is among the lowest in Europe (27%). With a total area of 9.92 million hectares, Carpathian forests constitute over 70% of the total forested land in Slovakia and Romania, with Romania alone harboring more than 45% of all Carpathian forests. Most of the Carpathian forests are dominated by European beech (Fagus sylvatica), Norway spruce (Picea abies), oak (Quercus robur, Quercus petraea), and silver fir (Abies alba) stands, covering over 70% of the altitudinal range (with the highest point being Gerlachovský štít, 2655 m a.s.l., in the Slovakian Tatra Mountains). The Carpathian Mountains were characterized in terms of their forests in the period starting from Holocene deglaciation. Climate fluctuations and human activities have led to substantial changes in forest systems, and anthropogenic activities, such as logging, fire activities, and grazing, have shaped the distribution and structure of present-day Carpathian forests. The rapid climate change in recent decades adds uncertainty to the future development of these forest systems.
