Statistical approach for the estimation of watershed scale nitrate export: a case study from Melen watershed of Turkey
Authors: Akiner Muhammed Ernur , Akkoyunlu Atilla 
Published: May 2016

Abstract
Nutrient pollution such as nitrate (NO3−) can cause water quality degradation in rivers used as a source of drinking water. This situation raises the question of how the nutrients have moved depending on many factors such as land use and anthropogenic sources. Researchers developed several nutrient export coefficient models depending on the aforementioned factors. To this purpose, statistical data including a number of factors such as historical water quality and land use data for the Melen Watershed were used. Nitrate export coefficients are estimates of the total load or mass of nitrate (NO3−) exported from a watershed standardized to unit area and unit time (e.g. kg/km2/day). In this study, nitrate export coefficients for the Melen Watershed were determined using the model that covers the Frequentist and Bayesian approaches. River retention coefficient was determined and introduced into the model as an important variable.

Published: May 2016

Summary
The purpose of this study was to determine what communication and instructional techniques including coaching strategies were being implemented by coaches and physical education (PE) teachers working in residential or day schools for the deaf throughout the U. S. Further, to share this information with coaches and PE teachers in general education classrooms. Questionnaire was answered electronically from 32 coaches and PE teachers (38 % return rate). Topics in the survey included: a) types of sports/PE classes; b) mode of communication used; c) coaching and teaching techniques; d) coaching and teaching strategies; e) breakdowns in communication; f) advice to new coaches a teachers starting out in the field. Advice for new coaches, who had not previously worked with the individuals who are deaf or hard of hearing (D/HH), six themes emerged: become fluent in ASL, remember to get the student’s attention before you start signing, use a lot of modelling, role playing, and videos (when needed), keep it simple, stress the fundamentals and insist on repetition until skills are mastered, and be flexible, each player will learn differently. Our results suggest that targeted and adapted communication strategies in PE and physical activities play important role for individuals who are D/HH.
Analysis of Horizontal Displacements Measured over the Mining Operations in Longwall No. 537 at the Girondelle 5 Seam of the Bw Friedrich Heinrich-Rheinland Coal Mine
Authors: Tajduś Krzysztof 
Published: May 2016

Abstract
The article presents an analysis of the horizontal land surface displacements taking place as an effect of coal exploitation on the Girondelle 5 seam in the Friedrich Heinrich-Rheinland mine in Germany. The paper presents changes in displacement vectors measured on the surface following the progress of the exploitation face and an analysis of horizontal displacement measurements assuming that their magnitude is proportional to the profile of subsidence trough slope. Then, the values of horizontal displacement coefficient B are assessed for selected longitudinal and transversal calculation cross-sections of longwall No. 537.
Sub-Level Stoping in an Underground Limestone Quarry: An Analysis of the State of Stress in an Evolutionary Scenario
Authors: Cardu Marilena , Dipietromaria Sergio , Oreste Pierpaolo 
Published: May 2016

Abstract
The aim of this study was to evaluate the state of stress of a „voids-pillar“ structure excavated by means of the sub-level stoping method in an underground limestone quarry near Bergamo (Italy). Both the current structure of the quarry (i.e. the rooms exploited till now) and a possible future scenario were analysed using the (FDM) FLAC 2D code. The quarry has been in operation since 1927; at present, exploitation is carried out underground via the sub-level stoping method. Exploitation involves two levels, with 5 rooms on the upper level and 9 rooms on the lower level.
After analysing data obtained from laboratory and in situ tests carried out on rock samples and natural discontinuities, the geomechanical properties of the medium, knowledge of which is essential in order to establish the parameters that must be included in the numerical model, were evaluated.
The implementation of three numerical models made it possible to study both the present conditions of quarry exploitation and the evolution of the exploited rooms, as well as a possible expansion involving a third level of rooms. Using the results obtained regarding the stress-strain present in the pillars, a potential change in room geometry was proposed aimed at reducing the stress state inside the pillars, decreasing plasticity and increasing overall quarry safety.
Manifestations of Slovak and Rusyn Identity in Vasil Stefan Koban’s The Sorrows of Marienka and Excerpt from Michal
Authors: Židová Diana 
Published: May 2016

Abstract
Vasil Stefan Koban (1918-2007) was an American writer of Slovak origin. His cultural identity is, however, somewhere between Rusyn and Slovak, but all his writings were published in Slovak journals such as Slovakia, or Almanac run by National Slovak Society. The Slovak translation of his only novel, The Sorrows of Marienka, was published in 2006 with the subtitle Púť Slovákov za lepším životom do Ameriky. The book is about the life of his mother Marienka who after marriage to Ivan Kinda emigrates from Jarabina to Conemaugh, an American coal mine town. Excerpt from Michal: Biography of a Galician Coal Miner, 1906-1933 is a revised version of the story in which Michal, Koban’s father and Marienka’s second husband, loses his leg in an accident and he must stay in a hospital for a year. In both stories Koban uses lots of Slovak words, but on the other hand, he mentions that Michal helped to build the Russian Orthodox Church of St. John the Baptist in Conemaugh with other Galicians, his natives, since he was born in Habowa. Although he considered himself to be of Slovak origin, Koban is enlisted under Carpatho-Rusyn Literature in The Greenwood Encyclopedia of Multiethnic American Literature. The article focuses on manifestations of Slovak and Rusyn identity in Koban’s two most notable literary works.

Effect of hypoxia on the expression of genes encoding insulin-like growth factors and some related proteins in U87 glioma cells without IRE1 function
Authors: Minchenko Dmytro O. , Kharkova A. P. , Halkin O. V. , Karbovskyi L. L. , Minchenko O. H. 
Published: May 2016

Abstract
Objective. The aim of the present study was to investigate the effect of hypoxia on the expression of genes encoding insulin-like growth factors (IGF1 and IGF2), their receptor (IGF1R), binding protein-4 (IGFBP4), and stanniocalcin 2 (STC2) in U87 glioma cells in relation to inhibition of endoplasmic reticulum stress signaling mediated by IRE1 (inositol requiring enzyme 1) for evaluation of their possible significance in the control of tumor growth.
Methods. The expression of IGF1, IGF2, IGF1R, IGFBP4, and STC2 genes in U87 glioma cells transfected by empty vector pcDNA3.1 (control) and cells without IRE1 signaling enzyme function (transfected by dnIRE1) upon hypoxia was studied by qPCR.
Results. The expression of IGF1 and IGF2 genes is down-regulated in glioma cells without IRE1 signaling enzyme function in comparison with the control cells. At the same time, the expression of IGF1R, IGFBP4, and STC2 genes was up-regulated in glioma cells upon inhibition of IRE1, with more significant changes for IGFBP4 and STC2 genes. We also showed that hypoxia does not change significantly the expression of IGF1, IGF2, and IGF1R genes but up-regulated IGFBP4 and STC2 genes expression in control glioma cells. Moreover, the inhibition of both enzymatic activities (kinase and endoribonuclease) of IRE1 in glioma cells does not change significantly the effect of hypoxia on the expression of IGF1, IGF1R, and IGFBP4 genes but introduces sensitivity of IGF2 gene to hypoxic condition. Thus, the expression of IGF2 gene is resistant to hypoxia only in control glioma cells and significantly down-regulated in cells without functional activity of IRE1 signaling enzyme, which is central mediator of the unfolded protein response and an important component of the tumor growth as well as metabolic diseases.
Conclusions. Results of this study demonstrate that the expression of IGF1 and IGF1R genes is resistant to hypoxic condition both in control U87 glioma cells and cells without IRE1 signaling enzyme function. However, hypoxia significantly up-regulates the expression of IGFBP4 gene independently on the inhibition of IRE1 enzyme. These data show that proteins encoded by these genes are resistant to hypoxia except IGFBP4 and participate in the regulation of metabolic and proliferative processes through IRE1 signaling.
Mechanisms involved in the regulation of neuropeptide-mediated neurite outgrowth: a minireview
Authors: Lestanova Z. , Bacova Z. , Bakos Jan 
Published: May 2016

Abstract
The present knowledge, regarding the neuronal growth and neurite extension, includes neuropeptide action in the central nervous system. Research reports have brought much information about the multiple intracellular signaling pathways of neuropeptides. However, regardless of the differences in the local responses elicited by neuropeptides, there exist certain functional similarities in the effects of neuropeptides, mediated by their receptors. In the present review, data of the relevant studies, focused on G protein-coupled receptors activated by neuropeptides, are summarized. Particularly, receptors that activate phosphatidylinositol-calcium system and protein kinase C pathways, resulting in the reorganization of the neuronal cytoskeleton and changes in the neuronal morphology, are discussed. Based on our data received, we are showing that oxytocin increases the gene expression of GTPase cell division cycle protein 42 (Cdc42), implicated in many aspects of the neuronal growth and morphology. We are also paying a special attention to neurite extension and retraction in the context of neuropeptide regulation.
Micro RNAs: an arguable appraisal in medicine
Authors: Voglova K. , Bezakova J. , Herichova Iveta 
Published: May 2016

Abstract
Micro RNAs (miRNAs) represent a newly discovered class of regulatory molecules in the human body. miRNA is a short double stranded RNA sequence interfering with mRNA, causing in most cases, inhibition of translation. Synthesis of miRNAs shows an increasing developmental pattern and postnatally miRNAs are synthesized in all cells possessing transcriptional machinery. miRNAs usually target several mRNAs and therefore conclusive evidences proving their functions are not always ease to be acquired. In spite of this difficulty, functions of miRNAs were firmly established in the development, the cardiovascular and neural diseases, and cancer. Many miRNAs have been reported to be associated with physiological state of cells and/or tissues. This finding becomes fundamental, especially when consider that these miRNAs can be released from cell into intracellular space or circulation. Correlation between miRNA production in tissues and its contribution to multisource miRNA pool in the circulation is in a focus of biomarker-oriented researchers. Recently, circulating miRNAs have been suggested to be applicable as biomarkers in several types of cancer, cardiovascular injury, and diabetes. Role of miRNAs in the organism intercellular signaling is still under the broad investigation. Several miRNA mimics, intended for treatment of disease, are being currently tested in the clinical trials.

Published: May 2016

Abstract
Florists’ greens are becoming increasingly important in contemporary floristry. Numerous studies conducted on cut flowers have led to the development of technologies for their post-harvest handling; however, in the case of florists’ greens they are still insufficient. Moreover, the extensive range of florists’ greens lacks leaves and the leafy culms of grasses. The aim of this study was to determine the post-harvest longevity of the leaves and leafy culms of ornamental grasses conditioned in water solutions of gibberellic acid and 8-hydroxyquinoline sulphate. The post-harvest longevity of leaves was examined in cultivars of the following species: Glyceria maxima Hartm. ‘Variegata’, Miscanthus sinensis Thunb. ‘Zebrinus’ and Spartina pectinata Link. ‘Aureomarginata’. The post-harvest longevity of leafy culms was investigated in Alopecurus pratensis L. ‘Aureovariegatus’, Chasmanthium latifolium Michx., Miscanthus sinensis Thunb. ‘Silberspinne’, Pennisetum alopecuroides L. and Phalaris arundinacea L. ‘Picta’. Conditioning in gibberellic acid had a positive effect on the post-harvest longevity and fresh weight loss and the index of leaf greenness of leaves in the case of Miscanthus sinensis ‘Zebrinus’, while conditioning in 8-hydroxyquinoline sulphate improved fresh weight loss and the index of leaf greenness of the leafy culms of Miscanthus sinensis ‘Zebrinus’, Pennisetum alopecuroides and the leaves of Glyceria maxima ‘Variegata’.
Factors Contributing to SMEs Failure in Meeting Supplier Performance Standards
Authors: van Scheers Louise 
Published: May 2016

Abstract
This study sought to determine the factors that contribute to the failure of small and medium enterprises (SMEs) in meeting supplier performance standards. Suppliers are faced with the challenge of SMEs failing to meet supplier performance standards because they rely on these providers of products and services, mainly SMEs, for their operations and to ultimately achieve their mandate. The researchers were able to establish the main factors contributing to SME failure in meeting supplier performance standards. These are as follows: unclear specifications and terms of references from suppliers; insufficient information provided to SME suppliers to ensure understanding of requirements; insufficient feedback and support; no support of SME suppliers based on their Black Economic Empowerment (BEE) status; limited or no use of business support programs by SME suppliers; and external factors such as access to finance, changes in the economy, and location.
New Factors Inducing Changes in the Retail Banking Customer Relationship Management (CRM) and Their Exploration by the Fintech Industry
Authors: Kotarba Marcin 
Published: May 2016

Abstract
Growing levels of regulation force financial institutions to change their business models toward lower risk levels, higher capital adequacy, service quality, and more stable revenue pools. In parallel with the regulatory changes, the banks are subject to pressure from accelerated technology development and social changes. These two factors influence the behavior of customers and induce changes in the customer relationship management (CRM). Taking the example of retail banking, the factors and their impacts are explained. Additionally, a view on the FinTech industry is presented, highlighting areas where traditional financial institutions are losing market share to technology-savvy and socially oriented new ventures with exceptional CRM capabilities. The conclusion contains proposed strategic actions that need to be undertaken in order to prepare the financial services industry for managing customer relationships in the increasingly technosocial environment.

Published: May 2016

Abstract
Staphylococcal toxic shock syndrome (TSS) is most frequently produced by TSS toxin-1 (TSST-1) and Staphylococcal enterotoxin B (SEB), and only rarely by enterotoxins A, C, D, E, and H. Various clinical pictures can occur depending on severity, patient age and immune status of the host. Severe forms, complicated by sepsis, are associated with a death rate of 50-60%. The case of a Caucasian female infant, aged seven weeks, hospitalized with a diffuse skin rash, characterized as allergodermia, who initially developed TSS with axillary intertrigo, is reported.
TSS was confirmed according to 2011 CDC criteria, and blood cultures positive for Methicillin-sensitive Staphylococcus aureus (MSSA). Severe development occurred initial, including acidosis, consumption coagulopathy, multiple organ failures (MOF), including impaired liver and kidney function. Central nervous system damage was manifest by seizures. Clinical management included medical supervision by a multidisciplinary team of infectious diseases specialist and intensive care specialist, as well as the initiation of a complex treatment plan to correct hydro electrolytic imbalances and acidosis. This treatment included antibiotic and antifungal therapy, diuretic therapy, immunoglobulins, and local treatment similar to a patient with burns to prevent superinfection of skin and mucous membranes lesions. There was a favourable response to the treatment with resolution of the illness.

Published: May 2016

Abstract
Jaundice in sepsis is usually caused by cholestasis, and its onset can precede other manifestations of the infection. Inflammation-induced cholestasis is a common complication in patients with an extrahepatic infection or those with inflammatory processes. We describe the case of a 47 years old female who presented with low back pain and paravertebral muscular contracture. She subsequently developed a cholestatic syndrome with clinical manifestations such as jaundice, followed by fever and sepsis with multiple organ dysfunction. Initially labeled as biliary sepsis, the diagnosis was crucially reoriented as the blood cultures were positive for Streptococcus pyogenes and the magnetic resonance imaging (MRI) findings suggested spondylodiscitis as well as a paravertebral abscess.

Published: May 2016

Abstract

Introduction: Intraabdominal pressure monitoring is not routinely performed because the procedure assumes some invasiveness and, like other invasive procedures, it needs to have a clear indication to be performed. The causes of IAH are various. Mechanically ventilated patients have numerous parameters set in order to be optimally ventilated and it is important to identify the ones with the biggest interference in abdominal pressure. Although it was stated that mechanical ventilation is a potential factor of high intraabdominal pressure the set parameters which may lead to this diagnostic are not clearly named.

Objectives: To evaluate the relation between intraabdominal pressure and ventilator parameters in patients with mechanical ventilation and to determine the correlation between intraabdominal pressure and body mass index. Material and method: This is an observational study which enrolled 16 invasive ventilated patients from which we obtained 61 record sheets. The following parameters were recorded twice daily: ventilator parameters, intraabdominal pressure, SpO2, Partial Oxygen pressure of arterial blood. We calculated the Body Mass Index (BMI) for each patient and the volume tidal/body weight ratio for every recorded data point.

Results: We observed a significant correlation between intraabdominal pressure (IAP) and the value of PEEP (p=0.0006). A significant statistical correlation was noted regarding the tidal volumes used for patient ventilation. The mean tidal volume was 5.18 ml/kg. Another significant correlation was noted between IAP and tidal volume per kilogram (p=0.0022). A positive correlation was found between BMI and IAP (p=0.0049), and another one related to the age of the enrolled patients. (p=0.0045).

Conclusions: The use of positive end-expiratory pressures and high tidal volumes during mechanical ventilation may lead to the elevation of intraabdominal pressure, a possible way of reducing this risk would be using low values of PEEP and also low volumes for the setting of ventilation parameters. There is a close positive correlation between the intraabdominal pressure levels and body mass index.
Analysis of time-fractional hunter-saxton equation: a model of neumatic liquid crystal
Authors: Atangana Abdon , Baleanu Dumitru , Alsaedi Ahmed 
Published: May 2016

Abstract
In this work, a theoretical study of diffusion of neumatic liquid crystals was done using the concept of fractional order derivative. This version of fractional derivative is very easy to handle and obey to almost all the properties satisfied by the conventional Newtonian concept of derivative. The mathematical equation underpinning this physical phenomenon was solved analytically via the so-called homotopy decomposition method. In order to show the accuracy of this iteration method, we constructed a Hilbert space in which we proved its stability for the time-fractional Hunder-Saxton equation.

Abstract
In this paper, we study the oscillation of solutions to a non-linear fractional differential equation with damping term. The fractional derivative is defined in the sense of the modified Riemann-Liouville derivative. By using a variable transformation, a generalized Riccati transformation, inequalities, and integration average techniquewe establish new oscillation criteria for the fractional differential equation. Several illustrative examples are also given.
