Ultramafic and Mafic Rocks Found in the Near Vicinity of Mariupolites within the Alkaline Oktiabrski Massif (SE Ukraine) – Preliminary Investigations
Authors: Dumańska-Słowik Magdalena , Heflik Wiesław 
Published: June 2016

AbstractThe preliminary results of the mineralogical and geochemical investigations of ultramafic (peridotite and pyroxenite) and mafic (olivine gabbro) rocks from the Mazurovski Field of the Oktiabrski Massif in South-eastern Ukraine are presented in this paper. Peridotite is mainly composed of olivine (forsterite), pyroxene (diallage), plagioclase (labradorite) and ore minerals such as magnetite, ilmenite and pyrite. Antigorite and talk are secondary components. Diallage with subordinate plagioclase, olivine and Fe compounds (oxides/sulphides) are found in pyroxenite. Gabro is made of two generations of plagioclase, diallage, olivine, biotite and amphiboles (hornblende and actinolite). Chlorite, talk and ore minerals (ilmenite, pyrite, Fe oxides/hydroxides) occur as its subordinate components. On the basis of their mineral composition peridotite was classified as wehrlite, pyroxenite as clinopyroxenite, whereas the mafic rocks are represented by olivine gabbro. The mafic rocks are most likely products orginating from calc-alkaline magma. Owing to the fact that chromite was not identified in periodite, it is very probable that this rock is loco-temperature differentation product of ultramorfic rocks. The ultrabasic rocks and enriched with Al2O3, CaO and Fe and complethy impoverished of REES and alkalis. Only one olivine gabbro shows some amounts of REEs (0.096 wt.% REEs with the distinct predominance of LREE over HREE) and alkalis (2.89–4.0 wt.% Na2O + K2O), which are surely genetically associated with alkaline rocks occurring in the near vicinity of the ultramafic and mafic rocks of the Oktiabrski Massif. The enrichment of gabbro in REEs and alkalis most probably proceeded post-magmatic activity.
Market Capacity of Coal for Heating and its Regional Differentiation as a Basis for Making Directions of Marketing Activities of Mining Companies in a Segment of Individual Customers
Authors: Bogacz Paweł 
Published: June 2016

Abstract
The article describes the importance of individual client in making level of demand for hard coal in Poland, and points to lack of use this potential by Polish hard coal producers. These arguments were derived firstly on the basis of analysis of the present structure of the hard coal market in Poland, including terms of the competitive situation. Secondly were taken into account characteristics of the level of demand for the product generated by the segment of individual clients. First of all the author focused on the second element, indicating the size and capacity of the quantitative and valuable part of the market for the year 2013. These analyses were carried out on the national level and in terms of individual provinces. In this way the level of the annual capacity of individual clients in Poland is 19.25 million Mg of hard coal. Taking into account prices of coal, calculation of the capacity of value is equal to 15.6 billion złoty per year. In regional terms the author also identified the most attractive in terms of capacity volumes and values Polish province, which included Mazowieckie and Silesia.
Prospective copper resources in Poland
Authors: Oszczepalski Sławomir , Speczik Stanisław , Małecka Kinga , Chmielewski Andrzej 
Published: June 2016

Abstract
The most significant copper reserves in Poland are confined to sediment-hosted stratiform Kupferschiefer-type deposits that occur at the Zechstein/Rotliegendes transition in the Fore-Sudetic Monocline and North-Sudetic Trough. Gradual depletion of shallow reserves results in exploitation of deeper beds. Latest studies of numerous drill hole cores strongly indicate that the Kupferschiefer series in SW Poland (outside the Lubin-Sieroszowice Copper District) contains a very large volume of prognostic, prospective and hypothetical resources.
38 prospects have been delineated (including 6 areas with prognostic resources, 4 with prospective resources, and 28 areas with hypothetical resources). Among the prospective areas, particular attention is paid to the areas adjacent to the existing mines of Lubin-Sieroszowice copper district, with prognostic resources (Białołęka, Grochowice, Kulów, Luboszyce). Also the areas: Nowiny, Żarków and Mirków are interesting due to accessible depths, Sulmierzyce and Janowo areas due to considerable resources and reasonable depth, and Mozów area – because of high Cu-Ag grading mineralized body with credible continuation to south east through Jany and Grochowice prospects, towards the Lubin-Sieroszowice mining district. It can be estimated that approximately 179 million tons Cu and 346 thousand tons Ag concentrated as potential resources in prospects of SW Poland for future mining, which will be possible, when geological and technological barriers (depth, temperature, oil and gas) will meet economic trends in the world market. Expected progress in underground mining at depths exceeding 1500 m (a depth limit for economic categories) will make this approach effective and technically possible.
Additional six prospective areas have been delineated in the contact zone between Upper Silesia and Małopolska blocks, where porphyry-type Mo-Cu-W mineralization (locally with skarns) occurs within porphyry/granitoid rocks and Ediacaran, Ordovician, Silurian, Devonian and Carboniferous metasediments and other sedimentary formations.
It should be noted, however, that irregular network of examined drill holes tended to simplify the ranges of prospects and to overestimate resource evaluation. Extensive deep exploration drilling is required to verify resource potential of granted and applied exploration licenses in several targets. The long-term challenges require new solutions for mining industry of the future and industrial market within the EU, to enable the reindustrialization of Europe.
Radiometric Methods of Monitoring of a Coal Separation Process in a Pulsating Jig
Authors: Cierpisz Stanisław , Kryca Marek , Sobierajski Waldemar , Gola Marian 
Published: June 2016

Abstract
A new monitoring system based on the monitoring of natural radiation emitted by the material in the separation zone of a jig compartment has been developed and tested in parallel with a radiometric density meter and a conventional float. The authors investigated the correlation between the separation density monitored by the meter and the intensity of the natural radiation. The measuring head of the radiometric density meter consists of a 137Cs radiation source and a detector in the form of a scintillation counter. The signal from the detector is measured over a period of 0.15 s at the end of each cycle of pulsations (1.2 s) when the material is compressed. The control systems were installed in the second compartment of the OM20-type jig. The aim of control was to stabilise the separation density at desired values. The separation process was monitored by a radiometric density meter (RDM) to indicate changes in the separation density over a given period of time. The RDM was installed close to the upper edge of the product overflow wall to measure the density of the material separation layer reporting in half to the product and in half to the refuse. A conventional float, indicating the position of the heavy fraction in the bed, was used as a basic sensor in the control system. After first experiments the RDM replaced the float as a main sensor in the closed loop control. In the third experiment a new monitor, based on the measurement of the natural radiation emitted by the material (NRM) accumulating below the product overflow wall was used. A good correlation between the NRM indications and the RDM measurements indicates that the radiometric density meter RDM can be replaced effectively by the NRM, especially in control systems where separation density is stabilised at desired values.
Thermogravimetric analyses (TGA) of lignins isolated from the residue of corn stover bioethanol (CSB) production
Authors: Tao Yubo , Li Shujun , Li Peng , Wu Qinglin 
Published: June 2016

AbstractIn the course of corn stover bioethanol (CSB) production, a lignin-rich residue is left behind, which is a potential feedstock for biofuel and other high-value products. In the present paper, this residual lignin was separated by precipitation from the alkali-solution and by extraction with organic solvents (benzyl alcohol, dioxane, and ethanol), respectively. Thermogravimetric analyses (TGA) at a heating rate of 30 K min-1showed that the degradation of all lignins took place in a temperature range between 400 K and 1073 K, with maxima at around 600 K. The char yield of alkali-lignin is higher than that of the CSB residue and the lignins isolated by organic solvents. Derivative TG (DTG) curves reflect well the comprehensive thermal degradation processes. The kinetic parameters according to the Kissinger’s method indicate that the CSB residue and all lignins follow approx. the first-order reaction law, except for benzyl alcohol lignin withn=1.4. As for the effects of separation methods, the DTG curves of benzyl alcohol lignin exhibited a less regular form and its wide temperature profile may have contributed to its apparently higher reaction order.

Published: June 2016

Abstract
At the turn of the 21st century, <100 Iberian lynx (Lynx pardinus) individuals were found to occur in Southern Spain. Research conducted when the species was that scarce identified Mediterranean scrubland as its breeding habitat. In recent years, the population has grown both in number of individuals and occupied surface. Here, we describe the use of olive tree plantations with low scrub density as breeding habitats by the Iberian lynx. Our results suggest that habitats that were formerly considered as non-suitable, such as agricultural land, could indeed host Iberian lynx breeding territories in areas with low scrubland coverage if wild rabbits are abundant.
Ninomiya–Victoir scheme: Strong convergence, antithetic version and application to multilevel estimators
Authors: Al Gerbi Anis , Jourdain Benjamin , Clément Emmanuelle

Abstract
In this paper, we are interested in the strong convergence properties of the Ninomiya–Victoir scheme which is known to exhibit weak convergence with order 2. We prove strong convergence with order

. This study is aimed at analysing the use of this scheme either at each level or only at the finest level of a multilevel Monte Carlo estimator: indeed, the variance of a multilevel Monte Carlo estimator is related to the strong error between the two schemes used on the coarse and fine grids at each level.
Recently, Giles and Szpruch proposed a scheme permitting to construct a multilevel Monte Carlo estimator achieving the optimal complexity

In the same spirit, we propose a modified Ninomiya–Victoir scheme, which may be strongly coupled with order 1 to the Giles–Szpruch scheme at the finest level of a multilevel Monte Carlo estimator. Numerical experiments show that this choice improves the efficiency, since the order 2 of weak convergence of the Ninomiya–Victoir scheme permits to reduce the number of discretisation levels.
A new proof of geometric convergence for the adaptive generalized weighted analog sampling (GWAS) method
Authors: Kong Rong , Spanier Jerome 
Published: June 2016

Abstract
Generalized Weighted Analog Sampling is a variance-reducing method for
solving radiative transport problems that makes use of a biased (though
asymptotically unbiased) estimator. The introduction of bias provides a
mechanism for combining the best features of unbiased estimators while
avoiding their limitations. In this paper we present a new proof that
adaptive GWAS estimation based on combining the variance-reducing power of
importance sampling with the sampling simplicity of correlated sampling
yields geometrically convergent estimates of radiative transport solutions.
The new proof establishes a stronger and more general theory of geometric
convergence for GWAS.

Authors: Zhu Xiangqian , Yoo Wansuk 
Published: June 2016

Abstract
Numerical simulation is an economical and effective method in the field of marine engineering. The dynamics of mooring cables has been analysed by a numerical simulation code that was created on a basis of a new element frame. This paper aims at verifying the accuracy of the numerical simulation code through comparisons with both the real experiments and a commercial simulation code. The real experiments are carried out with a catenary chain mooring in a water tank. The experimental results match the simulation results by the numerical simulation code well. Additionally, a virtual simulation of a large size chain mooring in ocean is carried out by both the numerical simulation code and a commercial simulation code. The simulation results by the numerical simulation code match those by the commercial simulation code well. Thus, the accuracy of the numerical simulation code for underwater chain mooring is verified by both the real experiments and commercial simulation code.

Published: June 2016

AbstractElectrochemical machining is an unique method of shaping in which, for optimal parameters tool has no wear, surface layer properties after machining are similar to the core material and surface quality and accuracy increase together with material removal rate increase. Such advantages of electrochemical machining, besides of some ecological problems, create industry interest in the range of manufacturing elements made of materials with special properties (i.e. turbine blades of flow aircrafts engines). In the paper the nowadays possibilities and recent practical application of electrochemical machining in aircraft have been presented.
Importance of Advanced Planning of Manufacturing for Nuclear Industry
Authors: Shykinov Nick , Rulko Robert , Mroz Dariusz 
Published: June 2016

Abstract
In the context of energy demands by growing economies, climate changes, fossil fuel pricing volatility, and improved safety and performance of nuclear power plants, many countries express interest in expanding or acquiring nuclear power capacity. In the light of the increased interest in expanding nuclear power the supply chain for nuclear power projects has received more attention in recent years. The importance of the advanced planning of procurement and manufacturing of components of nuclear facilities is critical for these projects. Many of these components are often referred to as long-lead items. They may be equipment, products and systems that are identified to have a delivery time long enough to affect directly the overall timing of a project. In order to avoid negatively affecting the project schedule, these items may need to be sourced out or manufactured years before the beginning of the project. For nuclear facilities, long-lead items include physical components such as large pressure vessels, instrumentation and controls. They may also mean programs and management systems important to the safety of the facility. Authorized nuclear operator training, site evaluation programs, and procurement are some of the examples. The nuclear power industry must often meet very demanding construction and commissioning timelines, and proper advanced planning of the long-lead items helps manage risks to project completion time. For nuclear components there are regulatory and licensing considerations that need to be considered. A national nuclear regulator must be involved early to ensure the components will meet the national legal regulatory requirements. This paper will discuss timing considerations to address the regulatory compliance of nuclear long-lead items.

Preventing and responding to gambling-related harm and crime in the workplace
Authors: Binde Per 
Published: June 2016

Aims Problem gambling, even if it occurs in leisure time, can cause harm in the workplace. Problem gamblers are preoccupied with gambling and often suffer from psychiatric and psychosomatic symptoms caused by their excessive gambling. This may lead to inefficiency at work and absenteeism. Severe gambling problems typically lead to a constant need for money, which may result in theft of money or goods from the workplace and in embezzlement. This paper outlines measures to prevent and respond to gambling-related harm and crime in the workplace. Methods A review of the literature and qualitative interviews with therapists specializing in problem gambling treatment, peer counsellors from mutual support societies, recovered problem gamblers who have embezzled, and professionals working in workplace crime security and the prevention of alcohol, drug and gambling harm. Results Important measures in preventing and responding to gambling harm in the workplace include: substance use and gambling policy, problem gambling awareness, attention to signs of gambling-related harm, control functions, appropriate responses to harmful gambling, and rehabilitation. Conclusion The workplace should play a greater role in the universal, selective and indicated prevention of problem gambling.
Pregnant substance-abusing women in involuntary treatment: Attachment experiences with the unborn child
Authors: Myra Siv Merete , Ravndal Edle , Torsteinsson Vigdis Wie , Wiig Eli Marie 
Published: June 2016

Background Use of coercion against pregnant women who misuse substances was legalised in Norway in 1996. The background for the law was that substance abuse during pregnancy represents a significant health problem for the child. Aim The main aim of this study was to explore if an attachment between the mother and her unborn child was possible in a context of coercion as experienced from the woman's perspective. The women had many challenges, such as lack of social support and poor living conditions. Material Data were collected in eight qualitative in-depth interviews. Findings The main findings show how involuntary detention enabled safety for and connection with the unborn child. Within this context, the pregnant substance-abusing women's own relational experiences and developmental histories represent the most significant barrier for their ability to bond with the expected child. Conclusions The study underlines the importance of helping women with their own attachment experiences in order to break the generational transference of risk and pathology, and in this way, start the attachment process to the unborn child during the coerced treatment stay. Implications of the findings are discussed.
Area, depth and elevation of cryoconite holes in the Arctic do not influence Tardigrada densities

Published: June 2016

Abstract
Water bears (Tardigrada) are known as one of the most extremophile animals in the world. They inhabit environments from the deepest parts of the oceans up to the highest mountains. One of the most extreme and still poorly studied habitats which tardigrades inhabit are cryoconite holes. We analysed the relation between area, depth, elevation and tardigrades densities in cryoconite holes on four glaciers on Spitsbergen. The mean (±SD) of cryoconite area was 1287.21±2400.8 cm2, while the depth was on average 10.8±11.2 cm, the elevation 172.6±109.66 m a.s.l., and tardigrade density 24.9±33.0 individuals per gram of wet material (n = 38). The densities of tardigrades on Hans Glacier reached values of up to 168 ind. cm3, 104 ind. g−1 wet weight, and 275 ind. g−1 dry weight. The densities of tardigrades of the three glaciers in Billefjorden were up to 82 ind. cm2, 326 ind. g−1 wet weight and 624 ind. g−1 dry weight. Surprisingly, although the model included area, depth and elevation as independent variables, it cannot explain Tardigrada density in cryoconite holes. We propose that due to the rapid melting of the glacier surface in the Arctic, the constant flushing of cryoconite sediments, and inter-hole water-sediment mixing, the functioning of these ecosystems is disrupted. We conclude that cryoconite holes are dynamic ecosystems for microinvertebrates in the Arctic.
