Published: January 2016

Abstract
Background
The aim of the present study was to investigate the incidence of adverse events (AEs) during intra-hospital transport (IHT) of critically ill patients and evaluate the risk factors associated with these events.

Methods
This prospective multicenter observational study was performed in 34 intensive care units in China during 20 consecutive days from 5 November to 25 November 2012. All consecutive patients who required IHT for diagnostic testing or therapeutic procedures during the study period were included. All AEs that occurred during IHT were recorded. The incidence of AEs was defined as the rate of transports with at least one AE. The statistical analysis included a description of demographic and clinical characteristics of the cohort as well as identification of risk factors for AEs during IHT by univariate and multivariate logistic regression analyses.

Results
In total, 441 IHTs of 369 critically ill patients were analyzed. The overall incidence of AEs was 79.8 % (352 IHTs). The proportion of equipment- and staff-related adverse events was 7.9 % (35 IHTs). The rate of patient-related adverse events (P-AEs) was 79.4 % (349 IHTs). The rates of vital sign–related P-AEs and arterial blood gas analysis–related P-AEs were 57.1 % (252 IHTs) and 46.9 % (207 IHTs), respectively. The incidence of critical P-AEs was 33.1 % (146 IHTs). The rates of vital sign–related critical P-AEs and arterial blood gas analysis–related critical P-AEs were 22.9 % (101 IHTs) and 15.0 % (66 IHTs), respectively. All data collected in our study were considered potential risk factors. In the multivariate analysis, predictive factors for P-AEs were pH, partial pressure of carbon dioxide in arterial blood, lactate level, glucose level, and heart rate before IHT. Furthermore, the Acute Physiology and Chronic Health Evaluation II score, partial pressure of oxygen in arterial blood, lactate level, glucose level, heart rate, respiratory rate, pulse oximetry, and sedation before transport were independent influential factors for critical P-AEs during IHT.

Conclusions
The incidence of P-AEs during IHT of critically ill patients was high. Risk factors for P-AEs during IHT were identified. Strategies are needed to reduce their frequency.

Abstract
Background
Type 1 diabetes mellitus (T1D) is characterized by autoimmune responses resulting in destruction of insulin-producing pancreatic beta cells. Multipotent mesenchymal stromal cells (MSCs) exhibit immunomodulatory potential, migratory capacity to injured areas and may contribute to tissue regeneration by the secretion of bioactive factors. Therefore, MSCs are considered as a promising approach to treat patients with different autoimmune diseases (AID), including T1D patients. Phenotypical and functional alterations have been reported in MSCs derived from patients with different AID. However, little is known about the properties of MSCs derived from patients with T1D. Since autoimmunity and the diabetic microenvironment may affect the biology of MSCs, it becomes important to investigate whether these cells are suitable for autologous transplantation. Thus, the aim of the present study was to evaluate the in vitro properties and the in vivo therapeutic efficacy of MSCs isolated from bone marrow of newly diagnosed T1D patients (T1D-MSCs) and to compare them with MSCs from healthy individuals (C-MSCs).

Methods
T1D-MSCs and C-MSCs were isolated and cultured until third passage. Then, morphology, cell diameter, expression of surface markers, differentiation potential, global microarray analyses and immunosuppressive capacity were in vitro analyzed. T1D-MSCs and C-MSCs therapeutic potential were evaluated using a murine experimental model of streptozotocin (STZ)-induced diabetes.

Results
T1D-MSCs and C-MSCs presented similar morphology, immunophenotype, differentiation potential, gene expression of immunomodulatory molecules and in vitro immunosuppressive capacity. When administered into diabetic mice, both T1D-MSCs and C-MSCs were able to reverse hyperglycemia, improve beta cell function and modulate pancreatic cytokine levels.

Conclusions
Thus, bone marrow MSCs isolated from T1D patients recently after diagnosis are not phenotypically or functionally impaired by harmful inflammatory and metabolic diabetic conditions. Our results provide support for the use of autologous MSCs for treatment of newly diagnosed T1D patients.
Remittances and child labor in Bolivia
Authors: Coon Michael 
Published: January 2016

Abstract
This article explores the effect of remittances on the prevalence and intensity of child labor in Bolivia. Using household survey data, we find that children in remittance-receiving households are less likely to be actively supplying labor, and the number of hours worked per week declines with the size of remittances received. The size of the impact varies between urban and rural households. Remittances to urban households have a larger impact on moving children completely out of the labor force, but a smaller increase in remittance size is needed for an equal reduction in number of hours worked in rural areas.

Published: January 2016

Part production by deep drawing technology brings important economic advantages. Cupping test is used to determine material suitability for deep drawing. The main principle of the test is redrawing of cylinder metal test piece to the cup. The result of the test is calculation of limiting drawing ratio (LDR) which states the ratio between the largest blank diameter and final cup diameter. Many cupping tests for various materials were performed in order to determine maximal value of LDR that would still allow deep drawing without failure of material integrity.Paper presents the theoretical determination of the limiting drawing ratio (LDR) in dependence on d0/t0 ratio and friction coefficient between blank and punch.Limiting drawing ratio (LDR) converges to Euler’s number (e) for high test piece depth and final cup diameter ratio values. Theoretical analysis of the cupping on drawing die with tractrix curve shows that maximal value of LDR may achieve value LDR>e. This is possible at lower values of test piece depth to final cup diameter ratio. Coefficient of friction has determining influence on LDR value.

Published: January 2016

Abstract
Contaminated storm-water discharge is a growing concern in the United States owing to a steady increase of harmful pollutants entering freshwater sources. This study remediated contaminated storm-water runoff from a bio-oil conversion facility through a simulated constructed wetland. A six-phase series of constructed wetlands was contaminated with varying dilution levels of bio-oil process water. The study concluded that there was a significant decrease in biological oxygen demand (BOD) and microtoxicity over a 10-day remediation cycle within the constructed wetlands for the lower levels of contaminated storm water. The higher levels of contamination changed very little in total volume of pollution. A comparative screening of the bacterial community within the wetlands during the contamination process showed a similar trend in species richness and composition for the first three phases of contamination. There was a shift in richness and diversity for the final three phases of contamination after 10 days. The constructed wetlands were successful at lowering BOD and toxicity levels and achieving permissible pH levels at dilutions higher than 500 times. When the concentrations of contaminated water were lower than 830 mL of contaminated bio-oil wastewater for every 240 liters of rainwater, the constructed wetlands were successful only at achieving permissible pH discharge levels. Better results for high-level contamination may be achievable with longer residence time in the wetlands.
Nonlinear structural analysis of a 2D cut-and-cover tunnel exposed to fire
Authors: Pouran Omid , Harte Reinhard , Peter Carsten 
Published: January 2016

Behaviour of cut-and-cover tunnels exposed to fire should be analysed by using a realistic model which takes account ofsimultaneous mechanical and thermal effects acting on the structure. This has been performed by 2D structural modelsfor a 2-cell tunnel with the aid of FE software package called SOFiSTiK (SOFiSTiK, 2014), in parallel, for two types of elements, beam and plate elements, as a scope of research project financed by BAST. The two considered models were levelled in terms of boundary conditions and the possible mechanical behaviour as well as mesh generation aspects.A nonlinearthermo-mechanical analysis has been performed considering pre-damaged effects on the cross sectionsby taking into account 10 and 15-minute time intervals for a whole duration of 90 minutes. The results of both models are in an acceptable agreement with each other,but they deviate from the simplified, linear-elastic calculation method considering a constant temperature gradient,DT<sub>M</sub> = 50 K,proposed by ZTV-ING Part 5 (BASt, 2013).To improve this method, a linear interpolation of different DT<sub>M</sub>-values with respect to the thickness of theconcrete member has been introduced.

Abstract
Given two holomorphic vector bundles E1 and E2, respectively endowed with two Finsler structures F1 and F2, we build a Finsler metric F on E1 ⊗ E2 involving F1 and F2. Under some hypothesis on global sections of E*1 and E*2, we give an optimal condition under which F is strongly pseudoconvex with negative curvature.
Simple crystallizations of 4-manifolds
Authors: Basak Biplab , Spreer Jonathan 
Published: January 2016

Abstract
Minimal crystallizations of simply connected PL 4-manifolds are very natural objects. Many of their topological features are reflected in their combinatorial structure which, in addition, is preserved under the connected sum operation. We present a minimal crystallization of the standard PL K3 surface. In combination with known results this yields minimal crystallizations of all simply connected PL 4-manifolds of “standard” type, that is, all connected sums of ℂℙ2, S2 × S2, and the K3 surface. In particular, we obtain minimal crystallizations of a pair of homeomorphic but non-PL-homeomorphic 4-manifolds. In addition, we give an elementary proof that the minimal 8-vertex crystallization of ℂℙ2 is unique and its associated pseudotriangulation is related to the 9-vertex combinatorial triangulation of ℂℙ2 by the minimum of four edge contractions.

Estimation Of The Mining Damage Risk In The Hypothetical Impact Area Of The Concurrent Processes Of Rock Mass Disorders
Authors: Piwowarski Wiesław , Isakow Zbigniew , Juzwa Jacek 
Published: January 2016

Abstract
The aim of this work is the estimation of the risk of mining damage occurrence, based on uncertain information regarding the impact of the concurrent processes of deformation and vibration. This problem concerns the experimental and theoretical description of the so-called critical phenomena occurring during the reaction mining area ↔ building object. Post-mining deformations of the rock mass medium and paraseismic vibrations can appear at a considerable distance from the sub-area of the mining operation – hence, the determination of the measures of their impacts is usually somewhat subjective, while the estimation of the mining damage based on deterministic methods is often insufficient. It is difficult to show the correlation between the local maximum of the impact of the velocity vector amplitude and the damage to the building – especially if the measures of interaction are not additive. The parameters of these impacts, as registered by measurements, form finite sets with a highly random character. Formally, it is adequate to the mapping from the probability space to the power set. For the purposes of the present study, the Dempster – Shafer model was used, where space is characterised by subadditive and superadditive measures. Regarding the application layer, the conclusions from the expert evaluations are assumed to be the values of random variables. The model was defined, and the risk of damage occurrence was estimated.
Point Movement Trace Vs. The Range Of Mining Exploitation Effects In The Rock Mass
Authors: Sroka Anton , Knothe Stanisław , Tajduś Krzysztof , Misa Rafał 
Published: January 2016

Abstract
The geometric-integral theories of the rock mass point movements due to mining exploitation assume the relationship between the progress of subsidence and horizontal movement.
By analysing the movement trace of a point located on the surface, and the influence of the mining exploitation in the rock mass, an equation describing the relationship between the main components of the deformation conditions was formulated. The result is consistent with the in situ observations and indicates the change of the rock mass component volume due to mining exploitation. The analyses and in situ observations demonstrate clearly that the continuity equation adopted in many solutions in the form:

$\sum\limits_{i = 1}^{i = 3} {\varepsilon _{ii}= 0}$

is fundamentally incorrect.
Some Aspects Of Using Goafs For Locating Post-Flotation Waste In LGOM Mines
Authors: Mazurkiewicz Maciej , Popiołek Edward , Niedojadło Zygmunt , Sopata Paweł , Stoch Tomasz 
Published: January 2016

Abstract
As a result of mining of deposits of mineral raw materials, spaces are formed in the rock mass, which get partially filled with roof rocks or by the backfill, most often sand. However, some voids remain in the rock mass, and can be used as a place to locate waste.
The thesis analyses systems and operating conditions of mining deposits, in terms of the possible existence of spaces for filling in the LGOM mines. It was determined that the most probable option is to use goafs after mining the ore with a thickness of over 3 m in the last 5 years, with the systems of roof deflection and their partial lifting. Quantitative evaluation of the voids is based on the comparison of the subsidence over the extraction field and the volume of the extracted deposit. It has been proved that the existing voids provide the possibility of locating approximately 8 million m3 of waste in goafs. It is highly possible to locate further 11 million m3 of waste after obtaining positive results of the practical location of them and gaining relevant experience. The goafs after mining with hydraulic filling, goafs in the deposit of the thickness of up to 2 m and mined more than 20 years ago were recognized as useless for locating waste.

Authors: Miladinović Branko , Vakanjac Vesna Ristić , Bukumirović Dragomir , Dragišić Veselin , Vakanjac Boris 
Published: January 2016

Abstract
The inflow of mine water to mining operations is often caused by random events such as precipitation. Consequently, the mine water inflow regime can be defined as a function of random events applying the theory of random processes.
Regression models of the multiple linear correlation type have been used to simulate the inflow of mine water into mining operations, produce short-range predictions and facilitate rapid response inside the mine. The significance of such models lies in the ability to simulate and predict the consequences (mine water inflow), caused by events of a random nature (meteorological parameters: precipitation and air temperature).
The presented prognostic models have been calibrated for mine water inflow to the Štavalj Coal Mine in southwestern Serbia. Mathematical dependencies were defined based on daily mine water inflow rates recorded during the period from 2003 to 2011, which can be used to generate short-range (1-7 day) predictions of mean daily mine water inflow rates to the Štavalj Coal Mine. A strong correlation (coefficient of correlation r = 0.93, Sig. = 0.00) was derived for the one-day forecast. The coefficients of correlation for predictions of mean daily mine water inflow rates related to time periods of two, three...seven days gradually declined to 0.63 (7-day mean daily inflow rate).
Neural Networks In Mining Sciences – General Overview And Some Representative Examples
Authors: Tadeusiewicz Ryszard 
Published: January 2016

Abstract
The many difficult problems that must now be addressed in mining sciences make us search for ever newer and more efficient computer tools that can be used to solve those problems. Among the numerous tools of this type, there are neural networks presented in this article – which, although not yet widely used in mining sciences, are certainly worth consideration. Neural networks are a technique which belongs to so called artificial intelligence, and originates from the attempts to model the structure and functioning of biological nervous systems. Initially constructed and tested exclusively out of scientific curiosity, as computer models of parts of the human brain, neural networks have become a surprisingly effective calculation tool in many areas: in technology, medicine, economics, and even social sciences. Unfortunately, they are relatively rarely used in mining sciences and mining technology. The article is intended to convince the readers that neural networks can be very useful also in mining sciences. It contains information how modern neural networks are built, how they operate and how one can use them. The preliminary discussion presented in this paper can help the reader gain an opinion whether this is a tool with handy properties, useful for him, and what it might come in useful for.
Of course, the brief introduction to neural networks contained in this paper will not be enough for the readers who get convinced by the arguments contained here, and want to use neural networks. They will still need a considerable portion of detailed knowledge so that they can begin to independently create and build such networks, and use them in practice. However, an interested reader who decides to try out the capabilities of neural networks will also find here links to references that will allow him to start exploration of neural networks fast, and then work with this handy tool efficiently. This will be easy, because there are currently quite a few ready-made computer programs, easily available, which allow their user to quickly and effortlessly create artificial neural networks, run them, train and use in practice.
The key issue is the question how to use these networks in mining sciences. The fact that this is possible and desirable is shown by convincing examples included in the second part of this study. From the very rich literature on the various applications of neural networks, we have selected several works that show how and what neural networks are used in the mining industry, and what has been achieved thanks to their use. The review of applications will continue in the next article, filed already for publication in the journal „Archives of Mining Sciences“. Only studying these two articles will provide sufficient knowledge for initial guidance in the area of issues under consideration here.

Published: January 2016

Abstract
Underground hard coal exploitation is often done under conditions of spontaneous fire hazard. The primary way to combat this threat is advanced, active or passive fire prevention. An important activity is the isolation of gobs using aqueous suspensions of fly ash as well as mineral binders. Therefore, the fine-grained suspension are often used in conditions of elevated temperature.
The paper presents results of research on the effect of temperature (up to 80°C) on the properties of suspensions in a liquid state, including their rheological parameters and setting time. Suspensions prepared using the ashes from the hard coal combustion in fluidized bed boilers, and with the addition of Portland cement CEM I 42.5.
During the research it was noted that the increased temperature significantly affect the acceleration of solidification processes of suspensions. In the case of rheological properties, the effect of temperature is ambiguous, among others, due to the phenomenon of sedimentation. However, in most cases, particularly for suspensions of higher solids content a marked increase in shear stress and viscosity of the suspensions with increasing temperature were observed.

Published: January 2016

Abstract
The paper presents the technology of processing Baltic cod (Gadus morhua callarias) and Atlantic salmon (Salmo salar) backbones – by-products from fish processing – for the production of calcium preparations. The raw material for the process consisted of backbones with remaining muscle tissue, devoid of heads and fins (30 kg of each type of backbones). The processing included the following stages: cutting, preliminary processing in an alkaline environment (soaking in 2 M NaOH), processing with 0.1% citric acid, aroma removal and material disinfection (5% H2O2), rinsing with tap water, drying, and grinding the end-product. Calcium preparations from cod (BCP) and salmon (ASP) in the amounts of 1.20 kg and 1.62 kg, respectively, characterized by high calcium content (27.79% in BCP, and 24.92% in ASP) and low protein and fat content (14.20% and 0.25% for BCP, and 10.78% and 0.12% for ASP, respectively) were obtained. The study demonstrated the effectiveness of this technology for production of calcium preparations from fish backbones.
