Acid biodesulphurisation of coal discards using a heap leaching approach
… amount of wastes, which include waste rock, coal discards, and coal fines, posing significant environmental risks. The presence of sulphidic minerals, particularly pyrite, in these wastes can lead to the formation of acidic runoffs, known as acid rock drainage (ARD), when exposed to moisture and …

Shadows of the Ravine: Mortality-Themed Discards from Bradbury's Illinois Novels
This thesis offers a focused examination of thematically-related story-chapters that Ray Bradbury originally intended for his first novel concept—Summer Morning, Summer Night, a book set in the vivid memories of his own small-town Midwest childhood. The stories at the heart of this thesis were …

Desulphurisation flotation for the selective removal of pyrite from coal discards using microorganisms
… produce large amounts of waste rock and coal discards that contain significant quantities of sulphide minerals with Acid Rock Drainage (ARD) generating potential. ARD is caused by the exposure of sulphide minerals, primarily pyrite (FeS2), to both water and oxygen, and microorganisms. This is …

Fish landings, discards and benthic material from demersal trawling in the western English Channel (ICES VIIe)
This study examined the impact of inshore single boat otter trawling from Newlyn, Looe, Plymouth and Salcombe and pair boat demersal trawling from Looe and Plymouth on the benthic environment off the SW peninsula of the UK between 1998 and 2000. Fish and shellfish species (54 and 11 species …

Development of co-disposal methods for coal discards and fine waste for the prevention of acid mine drainage
… has led to the considerable increase in coal discards (CD) and fine waste (FW) arising from mining and processing operations. These wastes typically contain sulphide minerals, which when oxidised may lead to the generation of acidic and toxic discharge. A deficit of naturally occurring …

Rory lines : silver lining for seabirds in South Africa's demersal trawl fisheries
… towards the trawl warps while feeding on factory discards alongside the vessel. The Albatross Task Force (ATF) helped to develop and test a new device, the Rory Line (RL), to be used in conjunction with tori lines, and designed to reduce warp strikes by placing a physical barrier between the …

Inventory management in a pharmaceutical company : minimizing discard practices
… company SPM has over 400 cases of inventory discards over the past five years which constitute a significant operating cost. Due to the complexity and randomness of each case, the root causes that result in inventory discards are not identified by the management, thereby hindering SPM from …

Using stable isotopes as a tool to understand the trophic relationships and movement of seabirds off Southern Africa
… natural prey whereas males take more fishery discards, although the sex-based difference was confounded by colony effect. Marked inter-colony variation probably results from regional differences in oceanic conditions between, prey availability and among gannets, variation in dependence on …

Discarding in UK Commercial Fisheries
… reform the CFP. A key objective is to eliminate discards and reduce unwanted catches. A discard ban and catch quotas for regulated species will be implemented. The EC argues that this will create strong incentives for more selective fishing, but little supporting evidence from EC fisheries is …

Mining Multifaceted Customer Opinions from Online Reviews
… natural language processing algorithms but discards valuable information in reviews that are not in the scope of the predefined construct. This study proposes a new method of extracting customer opinions and opinion targets from reviews with the Aspect Sentiment Triplet Extraction (ASTE) …

Validation of catch estimates for select species within the British Columbia groundfish hook-and-line catch monitoring program
… of species-by-area catch, including at-sea discards. The program, overseen by the Department of Fisheries and Oceans Canada, provides official estimates of total catch via fisher logbooks and dockside monitoring. This research provides a description of program components, examines weaknesses …

Inundation Flooding in Urban Environments using on-lattice Density Functional Theory
… of such an equilibrium-based approach, which discards the timedependence of flooding, stems from a combination of three aspects. First, the model has a minimum of input quantities and an efficient computational time. Second, the model comes with an ease of modeling a variety of city elements …

The Ethics of Humanitarian Intervention
… theorists should resist the emerging trend that discards right intention as a central requirement in favour of a more consequentialist analysis. I argue that interventions must be conducted in a manner that is consistent with the humanitarian purpose and would be accepted by the innocent …

Void Ecologies: Resistance, Commoning and Pleasure in the Discard Space
… By tracing the grassroots reclamation of discards across speculative, embodied and spatial dimensions in a sixty-year period (1964-2024), I demonstrate how these practices facilitate the development of “commoner” materially-linked consciousnesses that undermine and move in defiance of …

Addressing the impact of the EU CFP landing obligation on the northern North Sea ecosystem and Shetland fisheries in a changing climate.
… ocean warming. The model focusses on catch, discards and diets within ICES area IVa to represent specific mixed fisheries surrounding the Shetland Isles. The model uses stock assessments and North Sea International Bottom Trawl Survey (NS IBTS) data, tailored discard estimations and fish …

A systematic review of DTI studies in Bipolar Disorder
… or by a methodology which ignores tracts and discards potentially meaningful data. This background in the review includes a detailed exposition of the main DTI techniques and shortcomings. The review aims to determine whether certain white matter tracts are affected preferentially in the …

Parametrized maneuvers for autonomous vehicles
… parametric programming necessary conditions that discards the objective function, leaving a simple coordinatized feasible space including all dynamically admissible vehicle motions. A trajectory interpolation algorithm uses projection and integration methods to create the classes, starting from …

Models for project management
… difficult to manage: their non repetitive nature discards the trial and error learning, while their short life span is particularly unforgiving to misjudgments. Some authors have found that effective scheduling is an important contributor to the success of research and development (R&D), as well …

On the Geometric Characterization of the Lenke Classification Scheme for Idiopathic Scoliosis
… determines the Lenke Classification of each, and discards any curves that appear unnatural. By defining a metric that places an emphasis on certain geometric similarities, the software is able to define diameters of classification groups and separations between different classification groups. In …
