The symbiotic relationship of sediment and biofilm dynamics at the sediment water interface of oil sands industrial tailings ponds

Abstract. Aircraft-based measurements of methane (CH4) and other air pollutants in the Athabasca Oil Sands Region (AOSR) were made during a summer intensive field campaign between 13 August and 7 September 2013 in support of the Joint Canada–Alberta Implementation Plan for Oil Sands Monitoring. Chemical signatures were used to identify CH4 sources from tailings ponds (BTEX VOCs), open pit surface mines (NOy and rBC) and elevated plumes from bitumen upgrading facilities (SO2 and NOy). Emission rates of CH4 were determined for the five primary surface mining facilities in the region using two mass-balance methods. Emission rates from source categories within each facility were estimated when plumes from the sources were spatially separable. Tailings ponds accounted for 45 % of total CH4 emissions measured from the major surface mining facilities in the region, while emissions from operations in the open pit mines accounted for ∼ 50 %. The average open pit surface mining emission rates ranged from 1.2 to 2.8 t of CH4 h−1 for different facilities in the AOSR. Amongst the 19 tailings ponds, Mildred Lake Settling Basin, the oldest pond in the region, was found to be responsible for the majority of tailings ponds emissions of CH4 (> 70 %). The sum of measured emission rates of CH4 from the five major facilities, 19.2 ± 1.1 t CH4 h−1, was similar to a single mass-balance determination of CH4 from all major sources in the AOSR determined from a single flight downwind of the facilities, 23.7 ± 3.7 t CH4 h−1. The measured hourly CH4 emission rate from all facilities in the AOSR is 48 ± 8 % higher than that extracted for 2013 from the Canadian Greenhouse Gas Reporting Program, a legislated facility-reported emissions inventory, converted to hourly units. The measured emissions correspond to an emissions rate of 0.17 ± 0.01 Tg CH4 yr−1 if the emissions are assumed as temporally constant, which is an uncertain assumption. The emission rates reported here are relevant for the summer season. In the future, effort should be devoted to measurements in different seasons to further our understanding of the seasonal parameters impacting fugitive emissions of CH4 and to allow for better estimates of annual emissions and year-to-year variability.

This article discusses the symbiotic relationship of mutualism between mass media andterrorism. Whether we realize it or not, acts of terrorism in the homeland are still interestingand economically valuable news material in front of the mass media. On the other hand, onthe part of terrorists, the news about terrorist acts actually becomes a strategic campaignarea to show their existence. The research uses a qualitative approach to narrative analysismethod. The results of the study are www.okezone.com and www.tribunnews.com placingthe terror terror events in Medan Mapolrestabes as interesting and economically valuablenews material. The style of the news flow is arranged with a choice of tense, dramatic andsensational nuances of words. In addition, the display of photo and video illustrationsshortly after the explosion also aims to display as if the news of the explosion event is true,not engineering, objective and valid. The combination technique of choice of words, storyline, placement techniques and the size of photos and videos all aim to make the emotions ofthe reader participate dissolved in a tense situation as the situation at the scene of theexplosion. The practice of compiling this kind of news flow is called, as Jean Baudrillard'spractice of simulation. The practice of simulation through the practice of compiling newslines and the touch of visual image technology will eventually create conditions ofhyperreality. Namely the conditions between reality will be mixed with the pseudo so it isdifficult to distinguish which is original and fake. Next, the airing of a list of victims ofunknown origin will actually give birth, as Pierre Bourdie calls it symbolic violence. That is,the practice of violent symbols aimed no longer at the physical target but rather consciousthoughts. Symbolic violence in the appearance of the victim list really has the potential tocreate traumatic feelings towards the families of the victims.

The Relationship

The article explores the equation among nature, nation and gender in the nationalist context. Developing the argument that both nature and nation were feminised and deified as mother and mother goddess in the nationalist context, the article deploys feminist perspectives to critically examine this on a fourth-axis science. By looking at the relationship of the scientist, J. C. Bose, to these categories, the article hopes to unravel the complex relationship of the Indian scientist to nation, nature, gender and science. It is argued that due to being a ‘Sakta’, Bose had a symbiotic relationship to nature, and consequently to science, thereby presenting an ‘alternative’ to Western modes of relating to science and nature. The article submits that this alternative was cast in patriarchal constructions of both science and nature and views the associations of mother with nation and nature within larger feminist critiques of science. The article submits that while these sleeping metaphors set an alternative paradigm to the Western modes of relating to nature through science, they reproduced patriarchal constructions of the same. The article is an effort at grafting feminist perspectives on (a) science and (b) nationalism with postcolonial perspectives on science and modernity.

Analyze Data

This research aims to inventory local wisdom in the management and utilization of plants as food and medicine by local communities. The method conducted in this study is the purposive sampling method that aims to inventory plant species, direct observation, and analyze data by calculating density and basal area. The results showed 243 individual plants, consisting of 53 types of trees from 17 families, and found 29 types of plants were used as food and medicine. The utilization of plants by local communities varies. People use plant species for various benefits, namely foodstuffs, building materials, handicrafts, and traditional medicines. Local wisdom in the local community is the knowledge that lasts for generations and has a symbiotic relationship of mutualism with the forest ecosystem at the research site.
