Heap Leaching and the Water Environment – Does Low Cost Recovery Come at a High Environmental Cost ?

Heap leaching is a processing technology with low operating costs and is being increasing considered for the treatment of marginal grade metalliferous ores. However, heap leach facilities significantly modify the site water balance and pose a risk of process water loss to the receiving environment. Historic mismanagement of heap leach operations has caused widespread environmental damage, and civil society and regulators may therefore regard heap leaching with caution. Heap leach facilities may also prove challenging to regulate in terms of mining environmental legislation since they function as processing facilities during operation but become in situ waste facilities on closure.

Geometrical registration of images: the multiresolution approach

Geometrical registration of two images is nowadays a current and important step in remote sensing in view of further processing and interpretation of the data. Therefore, geometrical registration of images with different ground resolutions is useful for a better comprehension of dynamic processes (i.e., deforestation, desertification), as well as for extrapolating models of interpretation from a small region to larger areas. We present a new method of automatic registration, based on a multiresolution decomposition of the images using the wavelet transform. The main properties of this transform, as well as how the use of the wavelet model leads to an automated geometric matching between the different images, are described.
Psychophysiological effects of incentive feedback on unmanned aircraft operators’ mood and motivation

Extensive aerial surveillance using unmanned aerial vehicles require persistent motivation to monitor areas under surveillance, track people or vehicles, and carry out multiple checklists. Environmental factors and behavioural triggers can attenuate or enhance the approach motivation. The aim of this study was to test whether ambient lighting in the ground control station of an unmanned aerial vehicle and task feedback can incite motivation changes. Thirty participants were randomly allocated to a light (red, blue, or control) condition and a feedback (negative or positive) condition to test the effects of light and feedback on motivation during a 20-minute study. Self-report measures of mood state and motivation were taken while the participant completed two rounds of a visual search task before and after the ambient light and feedback interventions. Positive motivation increased in the blue light condition and decreased in the red and the control group relative to the baseline. No other significant effects were found, however trends in the data suggest that blue light raises approach motivation, and red light decreases approach motivation. The findings suggest that ambient interventions could be a useful tool to ensure a positive motivation is maintained for the operation of unmanned vehicles.
Constructing Urbanism: Relating the Construction of Architecture to the Process of Urbanization in the Middle Bronze Age Southern Levant

In this thesis, I seek a framework for understanding urbanization during the early Middle Bronze Age in the southern Levant by identifying and investigating patterns in the archaeological record during the transition from non-urban society and culture to a system of urbanism. The broad focus of my research is how urbanization occurred during this period, by specifically addressing three questions: (1) how were urban settlements built, in terms of materials and building practices? (2) what was the energetic cost of building cities, and how was this construction organized, in terms of resources and labour? and (3) how does this process of construction relate to the overall organizational processes of urbanization? I investigate patterns in the process of construction during this period by detailing architectural innovations throughout the region within their chronological and stratigraphic contexts. My methods include compiling databases of the dimensions of different aspects of architecture at a number of sites, as well as a detailed sampling and geoarchaeological analysis of mud-bricks at three case-study sites (Dan, Megiddo and Pella). By analysing bricks and reconstructing the process of their manufacture and use, I address the energetic cost of building cities, and how construction was organized, in terms of resources and labour. By highlighting the chaine opertoire of urban construction, I indicate the key socio-economic mechanisms in practice during urbanization and identify degrees of social organization through labour and material resources. Patterns of labour management and modes of production provide a window into social processes otherwise difficult to perceive, including possible power structures and discrete social entities. Taken together with other aspects of technological innovation during this period, architecture allows for a discussion of urbanization as a process of developing social complexity that is based on patterns of standardization measureable through the archaeological record.
Le renforcement des sols compressibles par inclusions rigides verticales : modélisation physique et numérique

Cette technique de renforcement associe un reseau d'inclusions et un matelas constitue de sol granulaire, intercale entre le sol renforce et l'ouvrage. Dans ce matelas se developpement des voutes qui transferent partiellement les charges vers les inclusions, permettant ainsi la reduction et l'homogeneisation des tassements en surface du massif renforce. Le renforcement peut etre complete par une nappe geosynthetique en base du matelas. Les domaines d'application sont les fondations de remblais routiers et ferroviaires et les fondations de zones industrielles. Les differents elements de ce systeme sont en interactions complexes. Ce travail contribue a la comprehension du comportement de ce type d'ouvrage, et s'interesse plus particulierement a la modelisation des mecanismes se developpant dans le matelas de transfert de charge. Une base de donnees experimentale est constituee, afin de servir de reference a des modelisations numeriques. Pour cela, un modele physique bidimensionnel mettant en œuvre des materiaux analogiques est developpe. La premiere etape de la modelisation numerique consiste en une modelisation bidimensionnelle en milieu continu, validee a partir des resultats experimentaux obtenus. Des modeles de comportement specifiques aux divers materiaux sont mis en œuvre. L'analyse est etendue numeriquement. La seconde etape de la modelisation tridimensionnelle en milieu continu de cas realiste. Les comportements du sol du matelas et du sol compressible sont pris en compte par des modeles de diverses complexites. Le systeme est d'abord pris en compte par une cellule elementaire, puis par une section courante de remblai.
2 The model : equation of motion and vacuum solutions

f(Ricci) gravity is a special kind of higher curvature gravity whose bulk Lagrangian density is the trace of a matrix-valued function of the Ricci tensor. It is shown that, under some mild constraints, f(Ricci) gravity admits Einstein manifolds as exact vacuum solutions, and can be ghost free around maximally symmetric Einstein vacua. It is also shown that the entropy for spherically symmetric black holes in f(Ricci) gravity calculated via Wald’s method and the boundary Noether charge approach proposed by Majhi and Padmanabhan are in good agreement.
A Benthic Survey of Inner Bantry Bay

In February 1993 sediment samples were collected from a total of 18 stations in Bantry Harbour, Glengarriff Harbour and along the north shore of Whiddy Island. The samples were analysed for grain size, organic carbon content and the abundance of benthic infauna. The benthic infauna were identified to family level. The sediments in Bantry Harbour and Glengarriff Harbour were comprised of fine particles with typically >80% of the dry weight being in the silt/clay (<63 μm) fraction. In contrast, the sediments close to Whiddy Island contained relatively high amounts of coarser material. In Bantry Harbour a total of 53 families with 742 individuals were identified from the ten stations sampled. Of the 53 families identified, 21 were Polychaeta, 6 Bivalvia, 7 Gastropoda, 3 Echinodermata, and 16 Crustacea. A total of 31 families with 491 individuals were identified from the five stations sampled in the Glengarriff Harbour area. Of these 16 were Polychaeta, 4 were Bivalvia, 3 were Gastropoda, 1 was Echinodermata, and 7 were Crustacea. From the three stations sampled in the vicinity of Whiddy Island 47 families with 461 individuals were identified. Of these 23 were Polychaeta, 8 Bivalvia, 4 Gastropoda, 2 Echinodermata, and 10 Crustacea. In Bantry Harbour and Glengarriff Harbour cirratulid polychaetes were dominant and the benthic infaunal composition was indicative of stressed environmental conditions. In contrast, the sediments close to Whiddy Island exhibited a very healthy faunal composition with no one family predominating and high numbers of amphiuroid echinoderms were recorded from these sampling stations
Face Detection using Fusion of Skin Detection and Viola-Jones Face Detection

Face Detection is the first step of any automated face and facial expression recognition system. It is applied in many applications such as computer vision and biometric applications like face recognition, expression recognition and classification, security access systems, video surveillance, and intelligent human computer interaction. A false detection rate and slow detection speed remain major problems in face detection. In this paper, we present a method to avoid these problems, by combining skin detection and Viola and Jones Face detection. Skin detection is used to reject false positive. After determining all possible face candidate regions, the Viola Jones detector is applied to detect face. Our method has high detection rate and accuracy than an individual face detector. It can perform quiet well in complex background and varying lighting conditions when it is applied images with complex backgrounds. Experimental results show the effectiveness of the proposed method.

Results of the Puritan-American Museum of Natural History Expedition to Western Mexico. 5, Pliocene and Pleistocene megafossils from the Tres Marías Islands. American Museum novitates ; no. 1940

Metazoan invertebrates of Pliocene and Pleistocene age were collected by the junior author from Maria Madre and Maria Cleofas Islands during the expedition's visit to the Tres Marias Islands, March 23 to April 7, 1957 (see Emerson, 1958, for the itinerary). Although few species are represented in the collections, the occurrence of fossiliferous sediments on Maria Cleofas Island, the most southeasterly of this insular group, is recorded here for the first time. Brief notes on the stratigraphy and on a few lithologic specimens are also included. In order to give a more complete presentation of the Pliocene paleontology of these islands, the megafossils cited by Jordan and Hertlein (1926a) from Maria Madre Island are included in the present faunal list, and the nomenclature of the previously reported species has been brought up to date. Late Pleistocene fossils from Maria Cleofas Island are listed, with remarks on the paleogeographic significance of the assemblage. The present expedition's collections from Maria Madre
Hyporheic Exchange in the Petit Buëch, Southern France

A point bar along the Petit Buech in southern France was studied for the effect of the interaction between groundwater and surface water. This so-called hyporheic exchange was clearly visible at multiple locations on the point bar. Residence time increases when water from the river infiltrates into the subsurface, influencing the transportation of nutrients and pollutants. A fieldwork was performed to do measurements on elevation, porosity and hydraulic conductivity. Grain size measurements were performed to calculate a porosity of 0.18 to 0.35. Hydraulic conductivity was calculated using porosity and groundwater velocity, resulting in an average hydraulic conductivity of 0.16 m/s. In ArcGIS the measurements were interpolated. Interpolations showed locations of large hydraulic conductivity in the inland part of the study area. In groundwater flow model MODFLOW, random fields of hydraulic conductivity were imported for particle tracing experiments in PMPATH. These resulted in residence time distributions having an average residence time of ~20 days. Fluxes were calculated along the river boundary, indicating a surplus of water infiltrating into the area of 1.6 m/s. Either the water exfiltrates into gullies on the point bar or elsewhere beyond the study area.
FeatherNets: Convolutional Neural Networks as Light as Feather for Face Anti-Spoofing

Face Anti-spoofing gains increased attentions recently in both academic and industrial fields. With the emergence of various CNN based solutions, the multi-modal(RGB, depth and IR) methods based CNN showed better performance than single modal classifiers. However, there is a need for improving the performance and reducing the complexity. Therefore, an extreme light network architecture(FeatherNet A/B) is proposed with a streaming module which fixes the weakness of Global Average Pooling and uses less parameters. Our single FeatherNet trained by depth image only, provides a higher baseline with 0.00168 ACER, 0.35M parameters and 83M FLOPS. Furthermore, a novel fusion procedure with "ensemble + cascade" structure is presented to satisfy the performance preferred use cases. Meanwhile, the MMFD dataset is collected to provide more attacks and diversity to gain better generalization. We use the fusion method in the Face Anti-spoofing Attack Detection Challenge@CVPR2019 and got the result of 0.0013(ACER), 0.999(TPR@FPR=10e-2), 0.998(TPR@FPR=10e-3) and 0.9814(TPR@FPR=10e-4).
Government mandated lockdowns do not reduce Covid-19 deaths: implications for evaluating the stringent New Zealand response

The New Zealand policy response to Coronavirus was the most stringent in the world during the Level 4 lockdown. Up to 10 billion dollars of output (≈3.3% of GDP) was lost in moving to Level 4 rather than staying at Level 2, according to Treasury calculations. For lockdown to be optimal requires large health benefits to offset this output loss. Forecast deaths from epidemiological models are not valid counterfactuals, due to poor identification. Instead, I use empirical data, based on variation amongst United States counties, over one-fifth of which just had social distancing rather than lockdown. Political drivers of lockdown provide identification. Lockdowns do not reduce Covid-19 deaths. This pattern is visible on each date that key lockdown decisions were made in New Zealand. The apparent ineffectiveness of lockdowns suggests that New Zealand suffered large economic costs for little benefit in terms of lives saved.
Psychosocial and Demographic Characteristics of Children and Adolescents With Headache Presenting for Treatment in a Headache Infusion Center

Approximately 10% of pediatric patients have recurrent headaches, with migraine being the most common headache type. If untreated, migraine may progress to status migrainosus, a debilitating condition of prolonged duration, high pain severity, and significant disability. There is high variability in the treatment of status migrainosus including medications used and treatment setting, which may occur in the emergency room, as an inpatient admission, or, less often, in an outpatient infusion center. The paucity of research on the treatment of status migrainosus is a limitation to treatment effectiveness.
Allogenic chondrocyte/osteoblast-loaded β-tricalcium phosphate bioceramic scaffolds for articular cartilage defect treatment

Abstract The medical community has expressed significant interest in the treatment of cartilage defect. Successful repair of articular cartilage defects remains a challenge in clinics. Due to the huge advantages of 3D micro/nanomaterials, 3D artificial micro/nano scaffolds have been widely developed and explored in the tissue repair of articular joints. In this study, chondrocyte/osteoblast-loaded β-tricalcium phosphate (β-TCP) bioceramic scaffold and chondrocyte-loaded β-TCP bioceramic scaffold were prepared by micromass stem cell culture and bioreactor-based cells-loaded scaffold culture for articular cartilage defect treatment. The results demonstrate chondrocyte and osteoblast can be successfully induced from allogeneic bone marrow stromal cells using micromass stem cell culture. Further, chondrocyte-loaded β-TCP scaffold and osteoblast-loaded β-TCP scaffold can be successfully prepared by bioreactor-based cells-loaded scaffold culture. Finally, the scaffolds are applied for Beagle articular cartilage defect treatment. The relative cartilage regeneration abilities on Beagle femoral trochleae were as follows: Chondrocyte/osteoblast-loaded β-TCP bioceramic scaffold group > chondrocyte-loaded β-TCP bioceramic scaffold group > β-TCP bioceramic scaffold. Therefore, micromass stem cell culture and bioreactor-based cells-loaded scaffold culture can be applied to prepare chondrocyte/osteoblast-loaded β-TCP bioceramic scaffold for articular cartilage defect treatment. It suggests allogenic chondrocyte/osteoblast-loaded β-TCP bioceramic scaffold could be potentially used in the treatment of patients with cartilage defects.

Early Cannabis Use and School to Work Transition of

We study the impact of early cannabis use on the school to work transition of young men. Our empirical approach accounts for common unobserved confounders that jointly affect selection into cannabis use and the transition from school to work using a multivariate mixed proportional hazard framework in which unobserved heterogeneities are drawn from a discrete mixing distribution. Extended models account for school leavers’ option of returning to school rather than starting work as a competing risk. We find that early cannabis use leads young men to accept job offers more quickly and at a lower wage rate compared to otherwise similar males who did not use cannabis. These effects are present only for those who use cannabis for longer than a year before leaving school. Overall, our findings are consistent with a mechanism whereby early non-experimental cannabis use leads to greater impatience in initial labor market
Relationships and responsiveness in the psychological treatment of trauma: The tragedy of the APA clinical practice guideline.

The therapeutic relationship and responsiveness/treatment adaptations rightfully occupy a prominent, evidence-based place in any guidelines for the psychological treatment of trauma. In this light, we critique the misguided efforts of the American Psychological Association's (APA, 2017) Clinical Practice Guideline on Posttraumatic Stress Disorder in Adults to advance a biomedical model for psychotherapy and thus focus almost exclusively on treatment methods for particular disorders. Instead, the research evidence, clinical expertise, and patient preferences and culture (the necessary triumvirate of evidence-based practice) should converge on distinctive psychological guidelines that emphasize the therapy relationship, treatment adaptations, and individual therapist effects, all of which independently account for patient improvement more than the particular treatment method. Meta-analytic findings and several trauma-specific studies illustrate the thesis. Efforts to promulgate guidelines without including the relationship and responsiveness are seriously incomplete and potentially misleading. The net result is an APA Guideline that proves empirically dubious, clinically suspect, and marginally useful; moreover, it squanders a vital opportunity to identify what actually heals the scourge of trauma. We conclude with recommendations for moving forward with future APA practice guidelines. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

FUELS FLEXIBILITY IN HEAVY-DUTY GAS TURBINES

INTRODUCTION World events have highlighted the critical role that fuels play in power production. The cost and availability of fuel are preeminent planning considerations. Consequently, the ability of any prime mover to burn a wide range of fuels-or fuels flexibility-continues to be of primary importance. In the past, most land-based gas turbines used natural gas or distillate fuels. A smaller but significant number used the lower-cost, poorer-grade fuels. During the past decade, however, there has been a decided change in this pattern. More and more, machines are being called upon to handle the lower-grade fuels, particularly in the international scene. Included in this category are blends, crudes, residual oils, and the lower heat-content gases. To this list will be added coal-derived fuels of the future. The purpose of this paper is to discuss the properties of the various fuels and how these properties influence GE heavy-duty turbine design and operation.
