В пределах Нижнего Новгорода и ближайших окрестностей в 400 точках измерены концентрации диоксида углерода и составлена карта его эмиссии. Концентрация углекислого газа варьировала от 311 до 913 ppm и в среднем составила 447 ppm, что выше среднего глобального уровня. Выявлены зоны с повышенным уровнем эмиссии углерода, связанные с промышленными пре...
The distribution of forests by categories of protection is analyzed in accordance with the current normative documents on forest management in the territory of the Russian Federation. It is noted that protective forests are divided into 4 groups of protection categories; each of them includes specific types of protection categories. A considerable ...
An accelerated carbonation method was applied to improve the ability of recycled aggregates to store CO 2 through the rolling carbonation process; moreover, recycled concrete aggregates' physicochemical properties to produce secondary aggregates for civil engineering applications were explored and evaluated. The carbonation tests were carried out i...
The sorption Phenolic wastewater is a kind of hazardous waste due to the presence of free phenol which is a highly toxic organic compound. Described in the literature and implemented, technology solutions for dephenolization are commonly based on thermal destruction. However, thermal treatment technologies have a range of disadvantages and the main...
Low-cost sensors for indoor air quality: performance assessment in simulated real conditionsaAs air quality is more and more a matter of interest among the general population, people strongly express the need to access real-time measurements with low-cost sensors easy to use. For indoor air, a lot of small, connected and low-cost sensors can now re...
The global aviation industry adopted a set of targets to mitigate CO2 emissions resulting from air transportation in 2009. The engine fuel burn is the main driver of CO2 emission; hence it will be the focus of this study. Rotorcraft are designed for supporting different types of missions or operations that are different from fixed wing aircraft. Fo...
The compact Earth system model OSCARv2.2 is used to assess the climate impact of present and future civil aviation carbon dioxide (CO2) emissions. The impact of aviation CO2 on future climate is quantified over the 1940–2050 period, extending some simulations to 2100 and using different aviation CO2 emission scenarios and two background Representat...
The global status of research on the effects of drought, temperature and elevated carbon dioxide (CO2) levels on the cacao plant, and the role of genetic diversity in producing more resilient cacao, are presented in this report. With the aim to enhance what we know about the resilience of cacao to climate change, and generate a comprehensive unders...
