Abstract. The Integrated Carbon Observation System (ICOS) is a pan-European research infrastructure which provides harmonized and high-precision scientific data on the carbon cycle and the greenhouse gas budget. All stations have to undergo a rigorous assessment before being labeled, i.e., receiving approval to join the network. In this paper, we present the labeling process for the ICOS atmosphere network through the 23 stations that were labeled between November 2017 and November 2019. We describe the labeling steps, as well as the quality controls, used to verify that the ICOS data (CO2, CH4, CO and meteorological measurements) attain the expected quality level defined within ICOS. To ensure the quality of the greenhouse gas data, three to four calibration gases and two target gases are measured: one target two to three times a day, the other gases twice a month. The data are verified on a weekly basis, and tests on the station sampling lines are performed twice a year. From these high-quality data, we conclude that regular calibrations of the CO2, CH4 and CO analyzers used here (twice a month) are important in particular for carbon monoxide (CO) due to the analyzer's variability and that reducing the number of calibration injections (from four to three) in a calibration sequence is possible, saving gas and extending the calibration gas lifespan. We also show that currently, the on-site water vapor correction test does not deliver quantitative results possibly due to environmental factors. Thus the use of a drying system is strongly recommended. Finally, the mandatory regular intake line tests are shown to be useful in detecting artifacts and leaks, as shown here via three different examples at the stations.

Ethical research that ensures the enhancement of quality of human life for present and future generations is the need of the day. This inherits the typical requirement to impose zero or minimal stress on the environment. Currently, planet earth is witnessing global warming and largely unpredictable weather changes, primarily due to greenhouse gas emissions. Transportation sector is one of the major engineering sectors contributing to greenhouse gas emissions. One way to mitigate/minimize these emissions is to use lightweight materials in the construction of vehicles for use in land, water, aerospace and space applications. Towards this, magnesium based materials are viable options which are suitable to replace aluminum based materials allowing ~ 35% weight saving on a component basis. As magnesium is abundant in nature and is a nutritional element, its availability and recyclability is not an issue. Accordingly, this paper will focus on the development of magnesium based nanocomposites capable of replacing conventional materials in multiple engineering and biomedical applications.

Feedlot management systems for beef cattle are becoming a more common practice in Australia reflecting opportunities to ensure quality of product whilst maintaining cost efficiencies within production. However, feedlot systems have been identified as point sources of greenhouse gases emissions (GGE: methane, nitrous oxide and the indirect greenhouse gas ammonia). It has been estimated that feedlot systems contribute 3.5% of total direct methane emissions (Alford et al. 2006), and 30% of total emissions from livestock wastes. Furthermore, approximately 1% of total N2O emissions from agriculture are attributed to livestock. This paper reports methane, N2O and NH3 emissions from an Australian feedlot system managed under summer climatic conditions. It compares actual measured emissions with estimated from three recognised models used by national governments to estimate total GGE per annum from livestock agriculture.

Air pollution is one of the main environmental reasons for many diseases in Bulgaria. Plenty of studies indicate that the country is still far from achieving air quality levels that do not pose a risk to people and the environment. The current research is directed toward eight companies in Bulgaria, which are responsible for over 70% of greenhouse gas emissions from fixed installations. The study was conducted during the period of 2016 to 2019. The main hypothesis is that due to the public importance of these companies’ activities, the quantity and quality of non-financial information disclosed by them will be significant. Additionally, it is examined how the required obligation for some companies to publish together with their annual financial statements and non-financial declaration has reflected on the disclosures made by them. The research is conducted on the basis of annual financial statements published by the companies, non-financial declarations, annual activity reports and information contained on their websites.

This paper aims at examining the integration of enterprise with biogas that contributes for quality of life in Nepal. The results have been estimated by using the data of FY 1992/93 to 2010/11. The number of biogas plants, cultural development, health and sanitation, reduction of greenhouse gas emission, forest conservation, and production of compost fertilizer has been comprised as variables for this study. Among others, Leslie Alvin White's model has been employed in this study. White introduced a formula, P = ET; Where, E is a measure of energy consumed per capita per year, T is the measure of efficiency in utilizing energy harnessed, and P represents the degree of cultural development in terms of product produced. The study establishes a significant role of enterprise integration with biogas for quality of life. It improves health and sanitation through providing clean energy and smokeless kitchen that directly associated with children and women's health and environment. The results shows improvement in people’s livelihood through starting agro & forest based micro enterprises by utilizing saved time due to biogas installation. Likewise, the study reveals that 415,314 tons of compost fertilizer can be produced annually that can promote agro-based enterprises. Moreover, 2.4 tons of reduction in greenhouse gas emission annually per household can be achieved by new Clean Development Mechanism (CDM) methodology. Last but not least, 296,653 trees can be protected per year that enhance greenery and protect environment. As a whole, all these factors contribute for enterprise integration in one way or another that play a vital role for the quality of life.Journal of Advanced Academic Research Vol.1(1) 2014: 68-75

The soil from three organically cultivated plots in Rioja Alavesa vineyards, specifically in Lanciego (Álava, Spain), and the foliage of their vines were analyzed. The aim of this study was to determine differences in soil and grapevine quality between different aged vineyards. The first 20 centimeters of the soil were sampled and leaves were collected during the growing season. The results show that the quality of the soil in the three plots was optimal and did not differ from reported values of soils from traditionally cultivated plots. The only element found at a lower concentration in the three plots and the leaves was iron. Organic cultivation of vineyards is a viable mode of cultivation and could help reduce greenhouse gas emissions and contamination by pesticides and fertilizers.
