To combat climate change increase in carbon sink or forest cover is most important adaptation technique. India has committed to create additional carbon sink of 2.5 to 3 billion tonnes of CO2 equivalent by 2030 in Intended Nationally Determined Contribution (INDC) submitted to Paris meet COP 21 (Conference Of Parties). A IPCC Tier II analysis of different mangrove sites of India will give a better snapshot of role of mangrove cover as carbon sinks to combat climate change and to achieve national target of carbon s...

Policies supporting rice cultivation and investments in water infrastructures facilitated intensification and diversification of land-use in the Vietnamese Mekong Delta. Although the major changes are acknowledged in the literature, few studies have examined the dynamism of land-use across the delta. Overlaying land-use maps, we identified land-use dynamic by the number of changes observed during the 11-year study period. Land-use was found to be highly variable, changing by 14.94% annually between 2001 and 2012. ...

The work is devoted to the new calibration method for vector geomagnetometer in the visualized coordinate system, which is connected with the body of the instrument. Standard navigation aids allows to transform geomagentic vector in the visualized coordinate system to the global coordinate system. It can be used for linking the received magnetograms to the coordinates on the terrain. The method allows to take into account the non-orthogonality of sensitive axes, difference of sensitivity and offset of magnetic fie...

Detailed geoecological mapping of anthropogenic heavily modified regions has its own specifics. A high degree of anthropogenic transformation of the landscape components affects the possibility of such mapping. Comprehensive positional analysis and synthesis at the geographical point was the main research method to the needs of allocating of types of geotopes. This method allows us to create complex geoecological relatively homogeneous units of small areas. This research was done in the cadastral territory of Porп...

Economists usually apply quantitative methods for analysing economic data. Most of this data has a connection to a particular place or space. In geography, the location plays a crucial role, and together with attributes of such location it represents geospatial data. Collaborative work of economists and geographers (geoinformaticians) offer great opportunities in geospatial-economic data analysis and visualisation. Joining two relatively distinct disciplines brings added value for both economy and geography. In ot...

Latvia has been actively involved in reducing global climate change. However, since 2006, along with an increase in economic activity, greenhouse gas emissions (GHG) from LatviaпїЅs agricultural sector have tended to increase; besides, the agricultural sector is the second largest source of GHG emissions, in 2015 accounting for 24.2% of the total GHG emissions in the country. Such changes in GHG emissions from agriculture in Latvia indicate that without additional measures Latvia cannot reach its GHG emission targ...

The literature mentions that marine algae biomass is an important resource of mineral elements, polysaccharides (agar-agar, alginats), proteins and vitamins. The superior valorification of this biomass represents a highly important resource for the pharmaceutical industry, textile and dyes industry, nutrition industry and for soil fertilization. At the Romanian Black Sea Coast the macro-algae biomass envelopment is reported mainly in summer and is registered especially by the green macro-algae group; thus the larg...

The marine ecosystem has been the cradle of life on Earth, and the entire evolution of human populations was related to the sea. Always present, in most great civilizations, from economy to art, the marine ecosystem always played a special and complex part in the human conscience and sole. Our article focuses on the relationship between certain factors of the marine ecosystems and both wellness and pathology of the eyes. Just like the tide of the sea goes both ways, so do the effects of the sea water and its assoc...

In the northwestern Black Sea the Danube deep sea fan has an extent of over 150 km and stretches from several hundred meters water depth down to the abyssal plain at 2200 m water depth. This large turbiditic system comprises a series of channel-levee systems, with deposits of mass transport. Its evolution was due to the fluctuations of sea level and sediment inputs. Sedimentary and seismic facies identified on the Danube deep sea fan are similar to those that characterize most fans of this type. In the study area ...

The microseismic monitoring is a method of monitoring of fracture propagation during hydraulic fracturing (HF)process. An array of several hundred geophones is placed on the surface to record little ground tremors induced by fracturing process. Filtration and summation of signals from geophones is essential to identify and locate fracturing events from underground. Authors propose a method of matched filtering, that is usually used for detection of outliers in music records, to improve signal to noise ratio. A rea...

One of the directions of rational use of energy resources in the field of drying of wood is the use of the managed heat pumps having the considerable potential for reduction of primary energy consumption when drying. Heat pumps can be used in combination with traditional fuel or electricity as an additional power source, or to act as the independent generator of heat and at the same time as draining device. The advantage of heat pumps is lower energy consumption for each unit of remote moisture, more exact managem...

The aim of the present work is to develop, substantiate, and study a fundamentally new method of derivation of composite electrolytic films making it possible to control their composition and structure.

The upper boundary of this field will descend with a velocity depending on the dispersity and density of a...

Soil contamination is a component that contributes to the increase of environmental pollution, as soil is the key element that underpins food production for household consumption. The transfer of contaminants from soil to plants is one of the input mechanisms of human exposure to metals through food chain. Mathematical models are documented as effective tools, that could help observe pollutants impact on agricultural products (vegetables and fruits) as well as on environmental systems, to evaluate different scenar...

Noxious agents released into the atmosphere that can cause harmful effects on human health and environment are often in the form of a complex of toxic substances in which both solid and gas particles are present. Polluting elements do not remain at the sources where they are produced, but due to influential factors, they are propagated to significant distances. Assessment of pollutant dispersion in the atmosphere is performed using mathematical dispersion models. This study presents the assessment of the impact of...

The noise in the workplace is a health problem of workers. It is estimated that a third of European workers are exposed to noisy working conditions more than a quarter of their working time. Hearing loss caused by noise is still one of the most common occupational disease in Europe, accounting for about one third of all occupational diseases. In order to identify employees and workplaces that are exposed to noise levels should to perform measurements of noise periodically. The methods for determining working condi...

The European Union has set a target to cut its greenhouse gas emission levels by 80% to 95% until 2050, if compared to 1990. Agricultural soil is an important carbon store and food provider in the world as well as greenhouse gas emission reducer via carbon sequestration. In order to assess the climate change mitigation effectiveness of the measures, it is necessary to obtain statistically significant data before and after the implementation. The greenhouse gas measurements from soil are commonly determined using s...

None of optical devices is perfect. Each lens has some errors, e.g. tilt, coma, spherical or chromatic aberration. The more lenses are in the optical device the more errors can reveal. All these imperfection accumulates and multiplies during the path through the optical device. It is necessary to know how the light passes through and interacts with each optical element. There are some possibilities of simulation of these defects. One of these methods is ENZ (Extended Nijboer-Zernike) theory which can be set up for...
