Kidd Mine – dealing with the issues of deep and high stress mining – past, present and future

Kidd Creek Mine is the deepest active base metal mine in the world, extending to a depth of 3 km below surface. The mine operators and engineers have met the ongoing challenges of mining sublevel open stopes at extreme depth through the utilisation of cutting edge technology, while expanding on a knowledge base encompassing 48 years of continuous operation under increasingly difficult conditions. Methods of dealing with geotechnical, logistical, and environmental challenges will be discussed, and areas for future development or pure research will be suggested.
Late childhood and adolescence growth sensitivity to political transition: the case of South African Cape coloured schoolchildren during and post-apartheid

Abstract South Africa underwent major social and economic change between 1987 and 1995. The release of Nelson Mandela in February 1990 proclaimed an end to the political system of apartheid, and the first freely elected non-White government in 1994 instigated social and economic reforms aimed at alleviating the consequences of apartheid. This paper aims to examine the impact of these socio-economic and political changes on height, weight and body mass index (BMI) in childhood and late adolescence. An analysis was carried out of longitudinal data of 258 urban and rural South African Cape Coloured schoolchildren (6-18 years old) across the transitional periods from apartheid between 1987 and 1990, to this transition between 1991 and 1993, and finally to post-apartheid between 1994 and 1995. The anthropometric measures were standardized into age independent Z-scores. Analyses of variance with repeated measures were conducted to examine the growth in height, weight and BMI across these periods. The results show a significant main effect of measurement periods on height, weight and BMI Z-scores. Across time, the subjects increased in overall size, height, weight and BMI. For all the anthropometric measures there was a significant interaction effect between measurement period and sex, but none between measurement period and SES. The average increase in height, weight and BMI across time differed significantly for girls and boys, the average z-scores being greater in girls than in boys. For boys, there was little difference in height, weight and BMI Z-scores according to SES, and little increase across periods. Girls were generally taller, heavier with greater BMI than boys, and their scores increased across the time periods. High SES girls were taller, heavier and had higher BMI than low SES girls. Across the measurement periods, BMI and weight somewhat converged between the high and low SES girls. In the discussion these differences reflecting social sex distinctions are addressed.

ETF Competition and Market Quality

Our paper investigates competition between ETFs that hold nearly identical baskets of securities. We provide strong evidence that incumbent-fund market quality is negatively affected when a new fund is added to an asset class. The degradation in liquidity is even more severe whenever both funds follow the same benchmark. Furthermore, increasing the number of ETFs in an asset class does not put downward pressure on expense ratios. Thus, decreasing market quality, enumerated by increasing bid-ask spreads and price impacts, is not offset by decreasing costs of fund ownership – resulting in a loss of surplus for investors and incumbent ETF providers.

Establishment risk from pet-trade freshwater turtles in the European Union

The pet-turtle market has grown in recent years and become an important pathway for the introduction of alien species in Europe. The import of Trachemys scripta elegans has been banned by European Commission Regulation due to its species’ expanding territory and negative impact on native species. Since the demand from hobby breeders persists, however, blocking imports of this popular subspecies opens up the possibility for the introduction of other potentially invasive turtles. We determined those turtle species most common in the pet trade within the Czech Republic, which is the most important producer, importer and exporter of ornamental aquatic animals in the EU. The determination of establishment risk for the EU as a whole was then individually evaluated for turtle species based on known establishment models. Chelydra serpentina , Apalone spinifera , Apalone mutica , and Sternotherus odoratus were considered most problematic, because these species have serious establishment risk and are imported to the EU in substantial numbers. Also localities in the EU were identified where probability is highest for establishment of non-native turtles.
Computed tomographic scanning measurement of skull bone thickness: a single center study

Background: Computerized tomography scan (CT scan) can be useful for the measuring the calvarial thickness in human beings. This could help in identifying the racial and the gender variations in calvarial thickness in a population. The data obtained about calvarial thickness study in human population may be useful for researchers, anatomists, anthropologists, surgeons and manufacturers of surgical screws. Methods: This was an observational study carried out on 104 subjects, with a normal computerized tomography CT scan of the head. Any subject with a skull fractures or an underlying intracranial lesion were excluded from study. A total of 52 males and 52 females who presented in the radiology department for CT head were studied in a consecutive manner. The thickness of skull bone was measured on console (Somatom, Siemens 16 slice). Results: Our study population consisted of 52 male and 52 female subjects. The mean age for males was 48.03 (Range 18-70) years and while as the mean age of females was 47.37 (Range 18-73) years. We did not find any difference in the thickness of the frontal bone at upper third, middle third and lower third between the two sexes. However, the posterior third parietal bone, the anterior and middle third occipital bone was significantly thicker in females when compared to males. Conclusions: Our study suggests that the anterior third of the parietal bone has a more calvarial thickness on the right side than on the left side in both males and females. However, the female calvarium has a significantly thicker calvarium at the posterior third parietal; anterior and middle third occipital bones when compared to male counterparts showing a sexual dimorphism in our study population.
SMALL AND MEDIUM ENTERPRISES AS AN EFFECTIVE SECTOR FOR ECONOMIC DEVELOPMENT AND EMPLOYMENT CREATION IN ALGERIA

This paper examines the current developments of small and medium-size enterprises (SMEs) in Algeria and investigates the contribution of those enterprises to economic development and employment creation. To this end the study uses the available data from the Algerian National Office of Statistics (ONS) and the Algerian Ministry of Industry, Small and Medium Enterprise and Investment Promotion; to analyze the effectiveness of those enterprises in terms of employment and wealth creation. The results of our research reveal that SMEs in Algeria are too fragile and do not contribute effectively to creating employment opportunities in which unemployment remains high, particularly among youth. Although Algeria has managed to diversify its economy, this diversification is still weak and the productive fabric remains largely concentrated in the hydrocarbon sector. In addition labor-intensive SME sector remains underdeveloped.
The Usefulness of Corporate Financial Reports: Evidence from the United Arab Emirates

The purpose of this paper is to examine the usefulness of financial reports to users in the United Arab Emirates (UAE). It is an attempt to find out whether current practices satisfy users’ needs of information and the extent to which these needs have been satisfied by the current disclosure practices of UAE companies. A survey questionnaire was used to explore whether the financial reports published by UAE firms were relevant to the needs of their users and to identify the disclosure items they perceived as important. Of the 512 questionnaires distributed to major external users of financial reports, 404 were returned. The results indicate that users in the UAE consider corporate annual reports to be the most important source of information. However, the level of corporate financial disclosure in the UAE does not provide sufficient information to the users. In fact, it meets only 61% of the needs reported by external users of financial reports. The users also nominated several areas of concerns, including delays in the availability of annual reports, the lack of creditability of financial information, and the non-accessibility of financial reports.

Trial of a special end user terminal that aids field operators during emergency rescue operations

This research is part of an EC Framework VI project called OASIS (Open Advanced System for dISaster and emergency management http://www.oasis-fp6.org/). OASIS involves developing an IT framework for interoperability in crisis management across national and agency boundaries and providing a number of applications to support user requirements. This paper discusses trials to evaluate an end user system that aids field personnel during emergency rescue operations. The system consists of a Head Mounted Display (HMD), camera, deployable ad-hoc wireless network and a noise reducing earpiece called PARAT which acts as a low noise voice pick-up for voice activated commands. The system presents relevant graphical and textual information to the users through a set of predefined commands and aims to improve communication between the operators. Eight fire-fighters participated in an evaluation trial utilising a simulated "Search and Rescue" scenario. A full system description, integration implications, scenario and results from the trial are presented.
Acquisition and evaluation of thermodynamic data for morenosite-retgersite equilibria at 0.1 MPa

Abstract Metal-sulfate salts in mine drainage environments commonly occur as solid solutions containing Fe, Cu, Mg, Zn, Al, Mn, Ni, Co, Cd, and other elements. Thermodynamic data for some of the endmember salts containing Fe, Cu, Zn, and Mg have been collected and evaluated previously, and the present study extends to the system containing Ni. Morenosite (NiSO4·7H2O)-retgersite (NiSO4·6H2O) equilibria were determined along five humidity buffer curves at 0.1 MPa and between 5 and 22 °C. Reversals along these humidity-buffer curves yield ln K = 17.58-6303.35/T, where K is the equilibrium constant, and T is temperature in K. The derived standard Gibbs free energy of reaction is 8.84 kJ/mol, which agrees very well with the values of 8.90, 8.83, and 8.85 kJ/mol based on the vapor pressure measurements of Schumb (1923), Bonnell and Burridge (1935), and Stout et al. (1966), respectively. This value also agrees reasonably well with the values of 8.65 and 9.56 kJ/mol calculated from the data compiled by Wagman et al. (1982) and DeKock (1982), respectively. The temperature- humidity relationships defined by this study for dehydration equilibria between morenosite and retgersite explain the more common occurrence of retgersite relative to morenosite in nature.
Surfing for Inspiration: digital inspirational material in design practice

Over the last decade, many new opportunities have emerged to support creativity and problem-solving in design by finding inspirational materials via the Internet. Online design communities such as those of Behance and Pinterest showcase portfolios and user-made artwork, and they offer support for d esigners’ day -to-day work to find and collect inspirational material. However, very little is known about how these communities affect inspiration-related practices of professional designers and how designers view them. This paper presents new data on the practices designers employ when seeking digital inspiration sources online and reflecting on, tracking, and managing them in today’s Web design. Current practice and views on sources of inspiration were described based on responses from 51 professional designers. The results suggest that the Internet has become a prevalent source for ideas in design, yet designers experience mounting issues of trust and relatedness with regard to online sources. Therefore, encouraging both should be considered a guiding principle for tools aimed at supporting designers within the realm of design practice.
Decay width and coupling constants of charm and bottom mesons.

In the last decade, charmed and bottom meson spectroscopy have seen great success in experimental sector. Experiments like LHCb, Babar etc are providing many new states which are being added to their spectroscopy. Newly predicted states like B(5970), D2(3000), D(3000), B(5840) and many more still need to be assigned their proper place in the spectroscopy. So we studied the decay constant and the coupling constants of these states using the heavy quark effective theory as our model. We analyzed the two-body strong decays of the above states to their ground state mesons with light pseudo-scalar mesons (p;h;K). We also obtained the ratios among their strong decays, which can be confronted to the experimental data for the verification of their JP states. In addition to this, we also study the strong decays of their spin and strange partners, which are still experimentally not observed, and may be useful for future experiments in searching for these heavy-light mesons.

Does sovereign debt ratings news spill over to international stock markets

The evidence here indicates that sovereign debt rating and credit outlook changes of one country have an asymmetric and economically significant effect on the stock market returns of other countries over 1989-2003. There is a negative reaction of 51 basis points (two-day return spread vis-a-vis the US) to a credit ratings downgrade of one notch in a common information spillover around the world. Upgrades, however, have no significant impact on return spreads of countries abroad. Closeness (e.g., geographic proximity) and emerging market status amplify the effect of a spillover. Downgrade spillover effects at the industry level are more pronounced in traded goods and small industries.
Progression of rabbit haemorrhagic disease virus 2 upon vaccination in an industrial rabbitry: a laboratorial approach

Rabbit haemorrhagic disease virus 2 (RHDV2) emerged recently in several European countries, leading to extensive economic losses in the industry. In response to this new infection, specific inactivated vaccines were developed in Europe and full and rapid setup of protective immunity induced by vaccination was reported. However, data on the efficacy of these vaccines in an ongoing-infection scenario is unavailable. In this study we investigated an infected RHDV2 indoor industrial meat rabbitry, where fatalities continued to occur after the implementation of the RHDV2 vaccination, introduced to control the disease. The aim of this study was to understand if these mortalities were RHDV2-related, to discover if the dead animals showed any common features such as age or time distance from vaccination, and to identify the source of the outbreak. Anatomo-pathological analysis of vaccinated animals with the virus showed lesions compatible with systemic haemorrhagic disease and RHDV2-RNA was detected in 85.7% of the animals tested. Sequencing of the vp60 gene amplified from liver samples led to the recognition of RHDV2 field strains demonstrating that after the implementation of vaccination, RHDV2 continued to circulate in the premises and to cause sporadic deaths. A nearby, semi-intensive, RHDV2 infected farm belonging to the same owner was identified as the most probable source of the virus. The main risk factors for virus introduction in these two industries were identified. Despite the virus being able to infect a few of the vaccinated rabbits, the significant decrease in mortality rate observed in vaccinated adult rabbits clearly reflects the efficacy of the vaccination. Nonetheless, the time taken to control the infection also highlights the importance of RHDV2 vaccination prior to the first contact with the virus, highly recommendable in endemic areas, to mitigate the infection’s impact on the industry.
Mealworm Powder as Culture Media of Local Isolate Semarang Entomopathogenic Nematodes

Many researchers confirmed that entomopathogenic nematodes (EPNs) of the genera Heterorhabditis and Steinernema can be cultivated in vitro using artificial media that containing animal nutrition. However, artificial media with insect component hasn’t been widely studied. This research aims to analyze the population of EPNs isolate of Semarang cultivated in mealworm powder media. Five doses of mealworm powder ( Tenebrio molitor ) were tested in this research, i.e: 0.5; 1.0; 1.5; 2.0 g. Culture media using 1 g of mealworm larvae was used as control. The best treatment was further tested for its pathogenicity on Macrotermes sp. at seven levels of invective juveniles (IJs) : 0; 50; 100; 150; 200; 250; 300 IJs/mL. Each treatment was repeated five times. The EPNs population and termites mortality were analyzed using ANAVA, whereas pathogenic value was calculated using Probit analysis. The result showed EPNs population were significantly (LSD test; α> 0.05), likewise on termites mortality. The EPNs isolate of Semarang optimally at 0.5 g mealworm powder and pathogenicity against termites based on LD 50 and LD 90 values at 220 JI/mL and 410 JI/mL doses, respectively. In conclusion, this result can be an alternative to mass cultivation of EPNs, in effort of development of local bioinsecticides. The findings of this study also inform farmers that EPNs can be easily cultivated using the simple and available materials.
Cross Correlation of Demands in Water Distribution Network Design

The aim of water distribution design is to size and configure a system so that it meets existing and future demands while providing pressures above a minimum level for service and fire protection. Extended period simulation EPS is used in design to determine network pressures under varied diurnal demand patterns. In EPS, diurnal demands are almost invariably assumed to change in unison, or in statistical terms, to be strongly correlated in space. This paper first tests this common assumption by investigating the extent to which cross correlation in demand affects the mean and standard deviation of pressure heads in water networks, and then investigates how cross correlated demands can influence capital costs in network design. Preliminary findings from two examples indicate that the standard deviation of pressure head and capital costs can be sensitive to the level of cross correlation between nodal demands. Thus a realistic assessment of cross correlation in demand can lead to a more economical design.

Damage to Residual Stand Caused by Mechanized Selection Harvest in Uneven- Aged Picea abies Dominated Stands

(L.) Karst) dominated stands in west-central Sweden. The objective was to quantify level and type of damage caused by harvesting and to quantify the difference between two treatments: T20) only skid road harvest (20 m distance between ca. 4 m wide roads), and T40) skid road harvest (40 m distance between ca. 4 m wide roads) combined with thinning between the roads. In T40, the goal was to harvest approximately the same standing volume as in T20. After harvest, two circular sample plots (radius 18 m, i.e. 1018 m
The use of referential cohesion in academic texts by Persian EFL learners

Writing cohesively remains a challenging task for many ESL and EFL learners and users of English, even at advanced levels. Despite its importance in academic writing, elements of cohesion have rarely been researched especially among Persian EFL writers. This study is aimed at filling the gap in the literature through an investigation of referential ties as one of the most explicit cohesion markers (Halliday and Matthiessen 2004). Papers by Persian scholars in the engineering field who attended a Nanotech conference in Malaysia, were reviewed for referential ties based on Systemic Functional Grammar (Halliday 1994; Halliday and Matthiessen 2004). The distribution and categorization of such ties were described using both descriptive and inferential statistics. Subsequently the reference usage by Persians who performed research in Malaysian and Iranian universities were compared. A discussion is presented to examine any improvements due to the environment for the group of Persians studying in Malaysian universities using English language as the medium of instruction. The results confirm that Persians studying in Malaysian universities produce and repeat some components of referential ties more frequently in their academic writing when compared with their peers studying in Iranian universities. In addition, the results of this study are compared with the findings of some other studies among ESL/EFL learners of different nationalities to explain the cases of overuse, underuse, and misuse of referential cohesion which has implications for pedagogical objectives.
