© 2018 by Taylor & Francis Group, LLC. ¿Mining¿ refers to the excavation of economically important resources from terrestrial landmasses, thereby generating a large quantity of valuable precursors for commercial and industrial activities. Mineral products such as coal, aluminum, copper, iron, gold, and mineral sand are examples from the mining industry. Though mining advances global economic prosperity, this industry severely disturbs the land, water resources, and the environment (Figure 4.1). Mined waste materials such as tailings, subsoils, oxidized wastes, and fireclay are the main causes for land disturbance. Presence of potentially hazardous substances such as heavy metals in elevated concentrations in the mined waste materials has caused land contamination. Poor soil characteristics such as low-level organic matter and poor soil texture and structure have resulted in deterioration of the land, adversely affecting the establishment of plants and soil microbial flora and fauna (Boyer et al. 2011, Johnson 2003, Larney and Angers 2012, Sopper 1992). Disturbed mine sites are known to contaminate water resources 60 61in many countries, mainly from acid mine drainage (Bolan et al. 2003, Lindsay et al. 2015, Taylor et al. 1997). Therefore, these sites need to be rehabilitated to minimize potential environmental consequences, thereby enhancing their utilization. Revegetation of mine sites is one of the potential strategies that can be applied to improve these disturbed land masses. Here, infertile soil properties are improved by a series of processes such as land application of biowastes

© 2018 by Taylor & Francis Group, LLC. Acid mine drainage (AMD) from both active and abandoned mine sites is a major environmental issue for the mining industry in environmentally concerned regions of the world (Gray 1997, Lindsay et al. 2015). The term is used to describe any seepage, leachate, or drainage affected by the oxidation products of sulfide minerals in mine sites when exposed to air and water (Figure 3.1). Both chemical reactions and biological transformations are recognized as being responsible for generating AMD (Lindsay et al. 2015). AMD is typically characterized by low pH and high levels of dissolved metal salts, as well as high concentrations of acidity, sulfate, iron, and other metals (Gray 1997). Once the AMD process begins, it is difficult to control, often accelerates, and is likely to persist for decades or centuries. In the absence of natural or added neutralizing materials 34(carbonate minerals such as calcite or dolomite), the AMD is likely to contain toxic levels of heavy metals such as Fe, Al, Mn, Cu, Pb, Zn, and Cd, which can cause serious environmental problems in soil and water systems (Sengupta 1994)

© 2018 by Taylor & Francis Group, LLC. Spoil to Soil: Mine Site Rehabilitation and Revegetation presents both fundamental and practical aspects of remediation and revegetation of mine sites. Through three major themes, it examines characterization of mine site spoils; remediation of chemical, physical and biological constraints of mine site spoils, including post mine-site land-use practices; and revegetation of remediated mine site spoils. Each theme includes chapters featuring case studies involving mine sites around the world. The final section focuses specifically on case studies with successful mine site rehabilitation. The book provides a narrative of how inert spoil can be converted to live soil. Instructive illustrations show mine sites before and after rehabilitation. The purpose of this book is to provide students, scientists, and professional personnel in the mining industry sensible, science-based information needed to rehabilitate sustainably areas disturbed by mining activities. This book is suitable for undergraduate and graduate students majoring in environmental, earth, and soil sciences; environmental and soil scientists; and mine site environmental engineers and regulators

© 2018 by Taylor & Francis Group, LLC. The Australian beef cattle industry is one of the most efficient and ranks third largest in beef export in the world, contributing 4% of beef supply. As on 2013, the meat value produced from beef cattle, in Australia is estimated to be $12.3 billion (Fastfacts, 2013). Beef cattle production ranges from intensive farms on fertile lands to extensive range lands. With the increase in human population and increase in affordability of meat-based food, the demand for beef cattle is also increasing

© 2018 by Taylor & Francis Group, LLC. Soils are a prime and very important natural resource, and soil fertility is a major concern for sustainable agriculture and economic development of any country. In recent decades, problems of contaminated land sites, water bodies, groundwater, and air worldwide have increased manyfold due to anthropogenic activities. Mining is one of the anthropogenic activities that cause pollution problems in, around, and outside of mining areas. It results in the mobilization of metals and organic and inorganic substances into the environment, which causes pollution of air, soils, sediments, vegetation, and surface and groundwater. It also increases the morbidity and mortality of plant and animal species and results in the loss of visual, aesthetic characteristics of landscapes (Bolan et al. 2003; Pavli et al. 2015)

© 2018 by Taylor & Francis Group, LLC. Degradation of land resources as a result of mining activities poses serious threat to the environment. It has been estimated that around 0.4 × 106km2area of land is impacted by mining activities around the world (Hooke and Martín-Duque 2012). Unfortunately, a significant percentage of this area has never been reclaimed, which poses health risks to ecosystems and humans. Often, these wastes contain hazardous substances such as heavy metals, organic contaminants, radionuclides, and crushed limestone, where the latter could become a potential source of atmospheric CO2emission. Thus, they not only pose serious risk to the groundwater and surface water, but also to the atmosphere (Wijesekara et al. 2016). In order to tackle the issues related to mine wastes and manage the affected sites sustainably, an appropriate physical, chemical, and biological characterization of waste materials becomes very prudent. Due to the lack of both above- and below-ground biodiversity, mine waste sites are very poor in organic matter content. This in return leads to poor seed germination, plant growth, and vegetation establishment. In many cases, the associated toxic contaminants also seriously compromise the soil health, microbial life, and plant growth (Castillejo and Castelló 2010, Larney and Angers 2012). This chapter describes the physicochemical characteristics of mine wastes, including spoil, tailings, and overburden, by underpinning their source-property relationships. The value of readily available biowaste resources, including biosolids, composts, and manures, in improving such physicochemical properties of mining-impacted soils/sites is also discussed

© 2018 by Taylor & Francis Group, LLC. Historically, mining of metalliferous ore bodies was a relatively dispersed activity, with numerous small mines occurring throughout many western countries including the United States, the United Kingdom, and Australia (Soucek et al. 2000, Grant et al. 2002, Mayes et al. 2009). Many metalliferous mine sites began operation in the late eighteenth and early nineteenth centuries and were abandoned in most instances before the environmental movement in Western countries. As such, there was very little recognition of the potential impacts caused by the dispersal of metal toxicants such as arsenic (As), cadmium (Cd), copper (Cu), lead (Pb), and zinc (Zn) into the surrounding environments from these sites. Many of these contaminants are cariogenic in humans (e.g., As), cause a range of human health-related impacts (Pb, Cd), and are toxic to ecological receptors in nearby streams and surrounding terrestrial environments (Cu, Zn, Mn, Ni). As a result of the lack of regard for potential impacts, much of the mining waste was discarded carelessly throughout mining sites, and in some cases, directly into nearby watercourses

© 2018 by Taylor & Francis Group, LLC. In the era of global competition, mineral exploitation has been significantly increased resulting in pressure on the environment in the form of massive deforestation, soil pollution, and erosion. Despite global economic importance, mineral industries have adversely affected the ecosystems across the world. The impact of mine waste in soil depends on its type and composition, commodity being mined, type of ore, and technologies used to process the ore. Mining types and activities are several, which include surface mining, underground mining, openpit mining, in situ mining, pillar mining, slope mining, block caving, and quarrying. And thus mine waste materials vary in their physical and chemical composition and potential for soil contamination. The different 96types of mine waste materials are overburden, waste rock, tailings, slags, mine water, sludge, and gaseous wastes. Overburden includes the soil and rock that are removed to gain access to the ore deposits at openpit mines. It is usually dumped on the surface at mine sites where it will not hinder further expansion of the mining operation. Waste rock contains minerals in concentrations considered too low to be extracted at a profit. It is often stored in heaps on the mine site. Tailings are finely ground rock and mineral waste products of mineral processing operations. They also contain leftover processing chemicals, and usually are deposited in the form of water-based slurry into tailings ponds. Slags are nonmetallic by-products from metal smelting. Mine water is produced in a number of ways at mine sites and varies in its quality and potential for environmental contamination. Sludge is produced at active water treatment plants used at some mine sites and consists of the solids that have been removed from the water as well as any chemicals. Gaseous wastes are produced during high-temperature chemical processing such as smelting, and consist of particulate matter and oxides of sulfur

© 2018 Informa UK Limited, trading as Taylor & Francis Group The purpose of this study was to establish a set of normative data (growth curve and centiles) for the Infant Monitor of vocal Production (IMP) using a representative population of infants with typically developing hearing. A linear mixed effect model and regression was used to derive ¿stage-for-age¿ trajectory and growth centiles from the standard sequence of IMP assessment scores of 85 infants with normal hearing (age range 3¿13 months). A significant linear relationship was demonstrated between IMP scores and infant age (p¿<¿.001). No significant relationship was found between IMP scores and gender, mono/bilingual language environment, singleton/sibling status, maternal education, or maternal work status. Inter-rater reliability and correlation for agreement was strong (0.94). These findings show that IMP assessment depicts the vocal development of infants with normal hearing as an hierarchical relationship between the complexity of infant vocal productions and infant age. Normative gains in vocal competency (-1SD/+1SD) approximated one IMP question per month of age from an infant¿s baseline level of IMP achievement.

© 2018 The University of Newcastle. Objective: Individual and environmental resilience protective factors are suggested to be associated with adolescent condom use; however, previous studies have not comprehensively examined such associations. This study aimed to determine the associations between condom use, and numerous individual and environmental resilience protective factors in sexually active Australian adolescents. Methods: Participants were Grade 10 students attending 28 Australian government high schools (n=1,688). An online survey (2011) collected data regarding: sexual intercourse (past year), condom use and 14 individual and environmental resilience protective factors. Multivariable backward stepwise logistic regression models examined associations between student condom use and protective factors (total, subscale). Results: Only total environmental protective factors remained in the final total score model; students with higher total environmental protective factors scores were 2.59 times more likely to always use a condom(95%CI:1.80-3.74). Only three of 14 protective factor subscales were associated with a higher likelihood of always using a condom in the final subscale model (individual: goals/aspirations; environmental: community participation, pro-social peers). Conclusions: Total environmental and three protective factor subscales demonstrated prominent associations with consistent use of condoms in sexually active adolescents. Implications for public health: Consideration of particular resilience protective factors in adolescent sexual risk behaviour prevention, such as condom use, is warranted.

© 2016 Elsevier Inc. This review aimed to determine the most popular physical activities performed by children, adolescents, and adults globally. Statistic bureau websites and article databases Scopus, ProQuest, SPORTDiscus, and Science Direct were searched between November 17th, 2014 and April 31st, 2015. Eligible studies were published in the last 10¿years with participation rates for specific physical activities among individuals five years or older. Data extraction for included articles (n¿=¿64) was assessed independently and agreed upon by two authors. A random-effects model was used to calculate participation rates in specific activities for each age group and region. In total 73,304 articles were retrieved and 64 articles representing 47 countries were included in the final meta-analysis. Among adults, walking was the most popular activity in the Americas (18.9%; 95% CI 10.2 to 32.5), Eastern Mediterranean (15.0%; 95% CI 5.8 to 33.6), Southeast Asia (39.3%; 95% CI 0.9 to 98.0) and Western Pacific (41.8%; 95% CI 25.2 to 60.6). In Europe and Africa, soccer (10.0%; 95% CI 6.5 to 15.1) and running (9.3%; 95% CI 0.9 to 53.9), respectively, were top activities. Child and adolescent participation results were highly dependent upon region. American youth team sport participation was high, while youth from the Eastern Mediterranean and Western Pacific were more likely to report participation in lifelong physical activities. Global data for adults reflects a consistent pattern of participation in running and walking. Among all age groups and regions soccer was popular. In children and adolescents, preferences were variable between regions.

© The Royal Australian and New Zealand College of Psychiatrists. Objective: Interventions are required to redress the disproportionate tobacco-related health burden experienced by persons with a mental illness. This study aimed to assess the efficacy of a universal smoking cessation intervention initiated within an acute psychiatric inpatient setting and continued post-discharge in reducing smoking prevalence and increasing quitting behaviours. Method: A randomised controlled trial was undertaken across four psychiatric inpatient facilities in Australia. Participants (N = 754) were randomised to receive either usual care (n = 375) or an intervention comprising a brief motivational interview and self-help material while in hospital, followed by a 4-month pharmacological and psychosocial intervention (n = 379) upon discharge. Primary outcomes assessed at 6 and 12 months post-discharge were 7-day point prevalence and 1-month prolonged smoking abstinence. A number of secondary smoking-related outcomes were also assessed. Subgroup analyses were conducted based on psychiatric diagnosis, baseline readiness to quit and nicotine dependence. Results: Seven-day point prevalence abstinence was higher for intervention participants (15.8%) than controls (9.3%) at 6 months post-discharge (odds ratio = 1.07, p = 0.04), but not at 12 months (13.4% and 10.0%, respectively; odds ratio = 1.03, p = 0.25). Significant intervention effects were not found on measures of prolonged abstinence at either 6 or 12 months post-discharge. Differential intervention effects for the primary outcomes were not detected for any subgroups. At both 6 and 12 months post-discharge, intervention group participants were significantly more likely to smoke fewer cigarettes per day, have reduced cigarette consumption by 3/450% and to have made at least one quit attempt, relative to controls. Conclusions: Universal smoking cessation treatment initiated in inpatient psychiatry and continued post-discharge was efficacious in increasing 7-day point prevalence smoking cessation rates and related quitting behaviours at 6 months post-discharge, with sustained effects on quitting behaviour at 12 months. Further research is required to identify strategies for achieving longer term smoking cessation.

© 2015 Australian College of Mental Health Nurses Inc. The implementation of smoke-free policies in inpatient psychiatric facilities, including patient adherence, mental health nursing staff support, and provision of nicotine-dependence treatment to patients, has been reported to be poor. The extent to which the quality of smoke-free policy implementation is associated with patient views of a policy is unknown. We conducted a cross-sectional survey of 181 patients (53.6%, n = 97 smokers; and 46.4%, n = 84 non-smokers) in an Australian inpatient psychiatric facility with a total smoke-free policy. Smokers' adherence to the policy was poor (83.5% smoked). Only half (53.6%) perceived staff to be supportive of the policy. Most smokers used nicotine-replacement therapy (75.3%); although few received optimal nicotine-dependence treatment (19.6%). Overall, 45.9% of patients viewed the smoke-free policy in the unit as positive (29.9% smokers; 64.3% non-smokers). For smokers, adhering to the ban, perceiving staff to be supportive, and reporting that the nicotine-replacement therapy reduced cravings to smoke were associated with a more positive view towards the smoke-free policy. These findings support the importance of patient adherence, mental health nursing staff support, and adequate provision of nicotine-dependence treatment in strengthening smoke-free policy implementation in inpatient psychiatric settings.

© The Author(s) 2014. Statistical analyses are important for real-world validation of theoretical model predictions. In this article, a statistical analysis of real data shows empirically how thermal resistance, thermal mass, building design, season and external air temperature collectively affect indoor air temperature. A simple, four-point, diurnal, temperature-by-time profile is used to summarise daily thermal performance and is used as the response variable for the analysis of performance. The findings from the statistical analysis imply that, at least for moderate climates, the best performing construction/design will be one in which insulation and thermal mass arrangements can be dynamically altered to suit weather and season.

Yet with the heterogeneous nature of many communication disorders, case studies allow clinicians and researchers to closely observe and report on change. Such information is valuable and can further inform large-scale experimental designs. In this research note, a statistical analysis for case-study data is outlined that employs a modification to the Reliable Change Index (Jacobson & Truax, 1991). The relationship between reliable change and clinical significance is discussed. Example data are used to guide the reader through the use and application of this analysis. Method: A method of analysis is detailed that is suitable for assessing change in measures with binary categorical outcomes. The analysis is illustrated using data from one individual, measured before and after treatment for stuttering. Conclusions: The application of this approach to assess change in categorical, binary data has potential application in speech-language pathology. It enables clinicians and researchers to analyze results from case studies for their statistical and clinical significance. This new method addresses a gap in the research design literature, that is, the lack of analysis methods for noncontinuous data (such as counts, rates, proportions of events) that may be used in case-study designs.

Dating back to 255 Mya, a diversity of vertebrate species have excavated mysterious, deep helical burrows called Daimonelix (devil's corkscrews). The possible functions of such structures are manifold, but their paucity in extant animals has frustrated their adaptive explanation. We recently discovered the first helical reptile burrows, created by the monitor lizard Varanus panoptes. The plugged burrows terminated in nest chambers that were the deepest known of any vertebrate, and by far the deepest of any reptile (mean = 2.3 m, range = 1.0-3.6 m, N = 52). A significant positive relationship between soil moisture and nest depth persisted at depths > 1 m, suggesting that deep nesting in V. panoptes may be an evolutionary response to egg desiccation during the long (approximately 8 months) dry season incubation period. Alternatively, lizards may avoid shallower nesting because even slight daily temperature fluctuations are detrimental to developing embryos; our data show that this species may have the most stable incubation environment of any reptile and possibly any ectotherm. Soil-filled burrows do not support the hypothesis generated for Daimonelix that the helix would provide more consistent temperature and humidity as a result of limited air circulation in dry palaeoclimates. We suggest that Daimonelix were used mainly for nesting or rearing young, because helical burrows of extant vertebrates are generally associated with a nest. The extraordinary nesting in this lizard reflects a system in which adaptive hypotheses for the function of fossil helical burrows can be readily tested.

© 2015 Informa UK Ltd. Decline in linguistic function has been associated with decline in cognitive function in previous research. This research investigated the informativeness of written language samples of Australian men from the Health in Men's Study (HIMS) aged from 76 to 93 years using the Computerised Propositional Idea Density Rater (CPIDR 5.1). In total, 60 255 words in 1147 comments were analysed using a linear-mixed model for statistical analysis. Results indicated no relationship with education level (p = 0.79). Participants for whom English was not their first learnt language showed Propositional Idea Density (PD) scores slightly lower (0.018 per 1 word). Mean PD per 1 word for those for whom English was their first language for comments below 60 words was 0.494 and above 60 words 0.526. Text length was found to have an effect (p = <0.0001). The mean PD was higher than previously reported for men and lower than previously reported for a similar cohort for Australian women.

© The Author 2014. Published by Oxford University Press on behalf of the Society for Research on Nicotine and Tobacco. All rights reserved. Introduction: Persons with a mental disorder smoke at higher rates and suffer disproportionate tobacco-related burden compared with the general population. The aim of this study was to determine if a smoking cessation intervention initiated during a psychiatric hospitalization and continued postdischarge was effective in reducing smoking behaviors among persons with a mental disorder. Methods: A randomized controlled trial was conducted at an Australian inpatient psychiatric facility. Participants were 205 patient smokers allocated to a treatment as usual control (n = 101) or a smoking cessation intervention (n = 104) incorporating psychosocial and pharmacological support for 4 months postdischarge. Follow-up assessments were conducted at 1 week, 2, 4, and 6 months postdischarge and included abstinence from cigarettes, quit attempts, daily cigarette consumption, and nicotine dependence. Results: Rates of continuous and 7-day point prevalence abstinence did not differ between treatment conditions at the 6-month follow-up; however, point prevalence abstinence was significantly higher for intervention (11.5%) compared with control (2%) participants at 4 months (OR = 6.46, p = .01). Participants in the intervention condition reported significantly more quit attempts (F[1, 202.5] = 15.23, p = .0001), lower daily cigarette consumption (F[4, 586] = 6.5, p < .001), and lower levels of nicotine dependence (F[3, 406] = 8.5, p < .0001) compared with controls at all follow-up assessments. Conclusions: Postdischarge cessation support was effective in encouraging quit attempts and reducing cigarette consumption up to 6 months postdischarge. Additional support strategies are required to facilitate longer-term cessation benefits for smokers with a mental disorder.

© 2014 John Wiley & Sons Ltd. Background: Convective warming is effective in maintaining core temperature under anesthesia. It may increase evaporative water loss (EWL). If significant, further investigation of warming modifications to minimize this impact would be warranted. Objectives: To quantify EWL in two groups of children (warmed and nonwarmed) having surgical procedures under anesthesia. Methods: We performed an observational study of well children having general anesthesia for elective surgical procedures lasting =60 min. They were recruited sequentially to each of three age groups: 1-12 months, 13 months - 5 years, and 5-12 years - with each age group divided into convectively warmed (43°C) and nonwarmed (21°C) subgroups. Evaporative heat loss (EHL) was calculated from accurate measurement of net EWL during the surgical period. Results: Sixty children were studied. As a percentage of body mass, mean EWLs were 0.29 (warmed) and 0.09 (nonwarmed). Using an ANCOVA model, only procedure duration had a significant impact and explained why the extended procedural time in some convectively warmed children led to higher mean EWLs for that group. For the nonwarmed group, the mean Tcoredrop was 1.27°C with a contribution from EWL of 0.6°C over ~70 min. Conclusions: Within the age range 1 month-12 years, EHL is not significantly influenced by convective heating under anesthesia. There is no thermal advantage in exploring technique modifications such as humidifying the warming air. Previous estimates of the contribution of EHL to total heat loss in anesthetized children may require revision.

Copyright (c) 2010 Mosby, Inc. All rights reserved. OBJECTIVE: To evaluate whether a child-centered physical activity program, combined with a parent-centered dietary program, was more efficacious than each treatment alone, in preventing unhealthy weight-gain in overweight children.STUDY DESIGN: An assessor-blinded randomized controlled trial involving 165 overweight/obese 5.5- to 9.9- year-old children. Participants were randomly assigned to 1 of 3 interventions: a parent-centered dietary program (Diet); a child-centered physical activity program (Activity); or a combination of both (Diet+Activity). All groups received 10 weekly face-to-face sessions followed by 3 monthly relapse-prevention phone calls. Analysis was by intention-to-treat. The primary outcome was change in body mass index z-score at 6 and 12 months (n=114 and 106, respectively).RESULTS: Body mass index z-scores were reduced at 12-months in all groups, with the Diet (mean [95% confidence interval]) (-0.39 [-0.51 to 0.27]) and Diet + Activity (-0.32, [-0.36, -0.23]) groups showing a greater reduction than the Activity group (-0.17 [-0.28, -0.06]) (P=.02). Changes in other outcomes (waist circumference and metabolic profile) were not statistically significant among groups.CONCLUSION: Relative body weight decreased at 6 months and was sustained at 12 months through treatment with a child-centered physical activity program, a parent-centered dietary program, or both. The greatest effect was achieved when a parent-centered dietary component was included.

The complexes [imH2]2 [CuCl4], [imH2], [CuBr4], and [imH2]2[ZnCl4] containing the imidazolium cation [imH2]+ have been prepared for the first time and studied by laser Raman and infrared spectroscopy. The spectroscopic data are compared to those from studies with imidazole, imidazolium chloride, methylammonium tetrachlorocuprate(II), caesium tetrachlorocuprate(II), and caesium tetrachlorozincate(II). It is concluded that in [imH2]2[MCl4] (M = Cu and Zn), a distorted tetrahedral (D2d) model is favoured for [CuCl4]2- and that [ZnCl4]2- possesses a slight distortion from Tdsymmetry. © 1973, CSIRO.
