Balance of Cost, Time, and Quality Related to Construction Projects Regarding the Reinforced Concrete of Underground Structures using a Meta-Heuristic Algorithm
Authors: Hosseini S. A. , Akbarpour A. , Ahmadi H. , Aminnejad B. 
Published: February 2018

AbstractUnderground spaces having features such as stability, resistance, and being undetected can play a key role in reducing vulnerability by relocating infrastructures and manpower. In recent years, the competitive business environment and limited resources have mostly focused on the importance of project management in order to achieve its objectives. In this research, in order to find the best balance among cost, time, and quality related to construction projects using reinforced concrete in underground structures, a multi-objective mathematical model is proposed. Several executive approaches have been considered for project activities and these approaches are analyzed via several factors. It is assumed that cost, time, and quality of activities in every defined approach can vary between compact and normal values, and the goal is to find the best execution for activities, achieving minimum cost and the maximum quality for the project. To solve the proposed multi-objective model, the genetic algorithm NSGA-II is used.
Efficiency and Limitations of Decompressive Craniectomy in Patients after Traumatic Brain Injury – Preliminary Results
Authors: Hanko M , Richterova R , Kolarovszki B. 
Published: February 2018

Abstract

Introduction: Decompressive craniectomy (DC) has been recently proven effective tier II therapeutic procedure in the treatment of refractory posttraumatic intracranial hypertension. However, its full potential and effectivity is yet to be described and this surgery remains controversial. The goals of our study include analysis of efficiency of DC and description of risk factors associated with unfavourable outcome.

Methods: 24 patients who underwent DC at the Clinic of Neurosurgery, JFM CU in Martin, during years 2015–2016 were prospectively observed. Selected demographic, clinical, and radiographic factors were analysed and compared with patient’s GOS (Glasgow Outcome Scale) at the time of their first ambulatory control (after 3.5 months in average).

Results: We observed mortality of 29.17 %. Good outcome (GOS 4–5) was achieved by 29.17 % of the patients as well. Preoperative GCS ≤ 5 (p = 0.049), intraventricular bleeding (p = 0.0268), midline shift ≥ 15 mm (p = 0.0067), and the volume of intracranial lesion (R = −0.41, p = 0.046), especially its extracerebral component (R = −0.46, p = 0.02), were identified as statistically significant negative prognostic factors.

Conclusion: DC is effective in the management of patients with traumatic brain injury. Good outcome is achieved by 29.17 % of the patients. Described negative prognostic factors (preoperative GCS ≤ 5, intraventricular bleeding, midline shift ≥ 15 mm, and increasing the volume of traumatic mass lesion) could help in targeting this surgery only to patients who are expected to benefit from it.
An Analog of the Neumann Problem for the 1-Laplace Equation in the Metric Setting: Existence, Boundary Regularity, and Stability
Authors: Lahti Panu , Malý Lukáš , Shanmugalingam Nageswari 
Published: February 2018

Abstract
We study an inhomogeneous Neumann boundary value problem for functions of least gradient on bounded domains in metric spaces that are equipped with a doubling measure and support a Poincaré inequality. We show that solutions exist under certain regularity assumptions on the domain, but are generally nonunique. We also show that solutions can be taken to be differences of two characteristic functions, and that they are regular up to the boundary when the boundary is of positive mean curvature. By regular up to the boundary we mean that if the boundary data is 1 in a neighborhood of a point on the boundary of the domain, then the solution is −1 in the intersection of the domain with a possibly smaller neighborhood of that point. Finally, we consider the stability of solutions with respect to boundary data.

Here we give a brief overview on the eighth annual conference on Modern Stellar Astronomy held in the Ural FederalUniversity (Ekaterinbourg, Russia) in June 2017, to commemorate the 100th birthday of Prof. K. Barkhatova (1917-1990).
Pragmatic Perspectives on Understanding Strangers
Authors: Várhegyi Nikolett , Furkó Péter 
Published: February 2018

AbstractThe present paper approaches the theme of “understanding strangers” through discussing some of the methodological issues in interlanguage pragmatics (ILP), with special reference to Hungarian-English Interlanguage (IL) requests. Written discourse completion tasks (WDCT) were used to collect data from 20 English major university students. The CCSARP Project’s 9-scale request strategies table proposed by Blum-Kulka, House, and Kasper (1989) was incorporated into the research, the proposed categories were extended by labels relating to mixed strategies and responses where no answers were provided. The structure of the paper is as follows: after a brief overview of the literature in the field of ILP with a special focus on WDCT, the validity of the methodology is highlighted through the discussion of issues relating to labelling/coding categories as well as interannotator (dis)agreements. By analysing and comparing utterances on the basis of our annotation output and validating the results with the aid of ReCal, we have confirmed that WDCT is a reliable and valid tool for testing ILP competence in speech acts performance.

Published: February 2018

Abstract
The main aim of this research was to implement appropriate Statistical Process Control (SPC) techniques for quality characteristics on sewing floor of garment Industry. Among different SPC quality improvements tools, control charts have been selected. After analyzing and selecting different critical parameters based on company and customer requirements, the X-bar and R charts for variable and c-charts for attribute quality characteristics have been identified and implemented in the trouser sewing lines for quality improvement. The check points for selected control chart implementation have also been designed. Remedial action plans for the occurred special cause variations and process stability were developed. The project incorporated theoretical and on-job training schemes for different quality team members, to understand the SPC concept and its implementation procedure. After implementation, significant improvements in the sewing section were achieved. The four months analysis before and after implementation of the SPC tools showed that the rejection percentage was reduced from 9.141% to 6.4%. Successful implementation of the result of this project can significantly improve process performance of other similar manufacturing units with appropriate modification.
Two Concepts of Freedom in Criminal Jurisprudence
Authors: Rosenberg Roni 
Published: February 2018

Abstract
The goal of this essay is to identify and discuss two aspects of liberty by examining the distinction between act and omission in criminal jurisprudence. Criminal law makes a significant distinction between harmful actions and harmful omissions and, consequently, between killing and letting die. Any act that causes death is grounds for a homicide conviction -- subject, of course, to the existence of the other elements necessary for establishing criminal liability, such as causation and mens rea. However, liability for death by omission is subject to the additional identification of a duty to act. In other words, the defendant will be liable only if we can identify such a duty and show that the breach of this duty resulted in the victim’s death. This distinction between act and omission is rooted in an ethical perspective, in which we instinctively see a difference between actively behaving in a manner that causes harm and passively failing to prevent such harm. Nevertheless, since the beginning of the 1960s, there has been a significant movement to attack and criticize this moral distinction. This critique impacts upon the legal sphere as well, since if the moral distinction between act and omission is not obvious, the legal distinction cannot be clear-cut either. This lack of clarity has led to many attempts to lay a logical foundation for the intuitive understanding that there is indeed a legal distinction between act and omission.
This essay focuses on two principles that reflect different aspects of human liberty which are reflected in criminal jurisprudence. The first is liberal liberty, and the second which I propose, is personal autonomy. While both relate to liberty of the individual, they approach it from different angles, and this difference in perspective results in different definitions of act and omission in criminal jurisprudence.
The Protection of Legitimate Expectations in Administrative Law: A Horizontal Perspective
Authors: Parchomiuk Jerzy 
Published: February 2018

Abstract
The term “protection of legitimate expectations” in administrative law traditionally draws our attention to vertical relationships between the State and an individual. In my text I propose a non-traditional approach to the issue of protection of legitimate expectations in administrative law. Instead of analysing the problem from the perspective of the relationship between the administrative body and the individual, I have attempted to tackle the problem from the perspective of entities involved in peer relationships.
The subject of my analysis is the principle of good faith as the axiological foundation for the protection of legitimate expectations in administrative law. Next the article addresses the specific legal institutions that express the protection of legitimate expectations in horizontal perspective: prohibition to make assertions contradictory to prior position (estoppel), institutions that express the protection of legitimate expectations in administrative contracts, as well as the principle of good faith in relationship between administrative bodies. The principle of good faith is a universal legal construct that forms the foundation of the legal system. Thus it is applicable in the sphere of administrative law, especially in the case of the relationship between equal-level entities.
Performance evaluation of cobas HBV real-time PCR assay on Roche cobas 4800 System in comparison with COBAS AmpliPrep/COBAS TaqMan HBV Test
Authors: Kim Hanah , Hur Mina , Bae Eunsin , Lee Kyung-A , Lee Woo-In 
Published: February 2018

Abstract

Background:
Hepatitis B virus (HBV) nucleic acid amplification testing (NAAT) is important for the diagnosis and management of HBV infection. We evaluated the analytical performance of the cobas HBV NAAT (Roche Diagnostics GmbH, Mannheim, Germany) on the cobas 4800 System in comparison with COBAS AmpliPrep/COBAS TaqMan HBV Test (CAP/CTM HBV).

Methods:
Precision was evaluated using three levels of cobas HBV/HCV/HIV-1 Control Kit, and linearity was evaluated across the anticipated measuring range (10.0–1.0×109 IU/mL) at seven levels using clinical samples. Detection capability, including limit of blank (LOB), limit of detection (LOD) and limit of quantitation (LOQ), was verified using the 4th WHO International Standard for HBV DNA for NAT (NIBSC code: 10/266). Correlation between the two systems was compared using 205 clinical samples (102 sera and 103 EDTA plasma).

Results:
Repeatability and total imprecision (coefficient of variation) ranged from 0.5% to 3.8% and from 0.5% to 3.5%, respectively. Linearity (coefficient of determination, R2) was 0.999. LOB, LOD and LOQ were all acceptable within the observed proportion rate (85%). Correlation was very high between the two systems in both serum and plasma samples (correlation coefficient [r]=0.995).

Conclusions:
The new cobas HBV real-time PCR assay on the cobas 4800 System showed reliable analytical performances.
Anti-streptavidin IgG antibody interference in anti-cyclic citrullinated peptide (CCP) IgG antibody assays is a rare but important cause of false-positive anti-CCP results
Authors: Berth Mario , Willaert Sofie , De Ridder Carol 
Published: February 2018

Abstract

Background:
The detection of anti-cyclic citrullinated peptide (anti-CCP) IgG antibodies in blood is mainly used for the diagnosis of rheumatoid arthritis. Falsely elevated anti-CCP IgG antibodies due to anti-streptavidin IgG antibodies were suspected in our laboratory.

Methods:
In this study, we evaluated, in a standardized approach, the prevalence of anti-streptavidin IgG antibodies in a primary care setting and the effect of anti-streptavidin IgG antibodies on anti-CCP IgG assays from three different important commercial manufacturers (Abbott, Roche Diagnostics, Thermo Fisher Scientific). Three different populations were consecutively and prospectively studied: serum samples from 1000 ambulatory patients, 286 serum samples from patients for which anti-CCP was requested and 89 serum samples from patients which had previously given a positive anti-CCP result on Architect® i2000.

Results:
The frequency of confirmed anti-streptavidin IgG-positive samples detected in this study was 0.6% (8/1375). Anti-CCP IgG was determined on the eight samples with confirmed anti-streptavidin IgG antibodies: with the Cobas® method, seven positive anti-CCP results were observed and five positive anti-CCP results with the Architect® method. No positive anti-CCP IgG results were obtained with the EliA™ method. Rheumatoid factor was negative in these eight samples.

Conclusions:
Anti-streptavidin IgG antibodies rarely cause false-positive results in some anti-CCP assays. However, despite being an infrequent assay problem, it could possibly lead to diagnostic confusion or even an incorrect diagnosis of rheumatoid arthritis.
Roman Jakobson in Retrospect

Abstract
An aperçu of the early years (1961–1965) in the life of a working scholar with a lasting record of achievement that touches on many details in the fraught relations between Roman Jakobson and the author, one of his most outstanding students. The account of these peripeteia, framed in cultural as well as biographical terms, provides an unusual insight into the sociology of knowledge as it pertains to the development of linguistics and semiotics in the twentieth century.
Continua and clustering processes
Authors: Ponzio Julia 
Published: February 2018

Abstract
Peirce’s definition of topology is strictly related to the connection models of the parts of continua. In the last part of his life, Peirce elaborated his topological analysis of continuity in order to answer some important questions which arose in his early works. This paper demonstrates that it is very important to connect the topological analysis of continuity with the questions it tries to answer. If not connected to the basic questions topology tries to answer, topological analysis may appear as the search for a hidden structure that keeps reality together, something to which reality must be traced back to be understood. This hidden structure is the continuum conceived as a precondition that justifies the unity of reality. By contrast, if we reconnect Peirce’s idea of continuum to the questions it attempts to answer, the continuum appears no longer as the condition of possibility for the relations that constitute the unity of reality. On the contrary, it appears as a form whose formation itself is conditioned by relations.
Solving systems of linear Boolean equations with noisy right-hand sides over the reals
Authors: Alekseev Evgeny K. , Oshkin Igor’ B. , Popov Vladimir O. , Smyshlyaev Stanislav V. 
Published: February 2018

Abstract
The paper is concerned with the problem of solution of a system of linear equations with noisy right-hand side in the following setting: one knows a random m × N-matrix A with entries from {–1, 1} and a vector xA + ξ ∈ ℝ
N
, where ξ is the noise vector from ℝ
N
, whose entries are independent realizations of a normally distributed random variable with parameters 0 and σ
2, and x is a random vector with coordinates from {–1, 1}. The sought-for parameter is the vector x. We propose a method for constructing a set containing the sought-for vector with probability not smaller than the given one and estimate the cardinality of this set. Theoretical calculations of the parameters of the method are illustrated by experiments demonstrating the practical implementability of the method for cases when direct enumeration of all possible values of x is unfeasible.
Cross-border Inter-Adriatic Cooperation: A Case Study
Authors: Sarno Emilia 
Published: February 2018

Abstract
The paper highlights the cultural and legislative framework which favours the cross-border cooperation between the countries on the shores of the Adriatic Sea. It looks at the importance of geographical and socio-economic proximity and analyses the formation of the Adriatic-Ionian Euro-region. This context is useful for the development of those territories, considered marginal, which can renew their economies through cooperation. As a case study, what is analysed is the possible cross-border relations between the Italian region Molise and Montenegro. The two territories have several elements in common and can use cooperation as a means of renewing their economy. Furthermore, the crossborder cooperation is the right strategy to modernise the agricultural sector and strengthen the tourism. For this reason, the paper aims to highlight how the cooperation is the lens through which we can identify the territorial potential which, when amplified through comparison, will emerge more clearly.
Biodegradable glucose and glucosamine grafted polyacrylamide/graphite composites for the removal of acid violet 17 from an aqueous solution
Authors: Kumarasamy Gayathri , Nachimuthu Palanisamy 
Published: February 2018

Abstract
In this work, the structural characterization and adsorption behavior of glucose and glucosamine grafted polyacrylamide/graphite composites (denoted as Gu-g-PAM/graphite and GA-g-PAM/graphite) were investigated. The grafted polymers were characterized by using Fourier transform infrared (FT-IR) spectroscopy, 1H nuclear magnetic resonance (NMR), 13C NMR and N2 sorption studies. The adsorption behavior of grafted polymers was compared by varying parameters such as pH, initial dye concentration, agitation time, adsorbent dose and temperature. The results showed that GA-g-PAM/graphite composite was an effective adsorbent for the uptake of acid violet 17 (Av-17) from an aqueous solution. The superior adsorption behavior was attributed to the presence of -NH2 and -OH groups in GA-g-PAM/graphite. Langmuir, Freundlich and Dubinin-Radushkevich (D-R) isotherms were used to describe the adsorption isotherm. The adsorption isotherm of the adsorbents fitted well with the Langmuir model with the maximum adsorption capacity (qo) of 78.13 mg/g for GA-g-PAM/graphite. The efficiency of adsorption with time was described using pseudo first-order, pseudo second-order and intra particle diffusion kinetic models. The kinetic study revealed that the adsorption equilibrium was attained within 50 min. The thermodynamic analysis stated that the adsorption of dye is spontaneous, physical and endothermic in nature. Desorption results revealed that all the adsorbents exhibit excellent stability and remarkable regeneration ability.
Control Premium and Minority Discounts in Polish Business Valuation Practices – Evidence from Research
Authors: Byrka-Kita Katarzyna , Grudziński Michał 
Published: February 2018

AbstractThe paper presents the results of a survey of business valuation practice in Poland. The aim of this study was to assess the premium for control as well as discounts for minority interests by practitioners involved in the valuation of companies in Poland. The survey was conducted on a sample of 191 respondents between February and April 2011. The population of entities under survey consists of: authorized NewConnect3 / Catalyst advisers, brokers, valuation analysts working for leading consulting firms, and experts appointed by the court. The evidence from the research demonstrates that most of respondents do not know how to apply premium control and minority discounts in business valuation. Incorrect approaches to the application of control premiums or minority discounts reflect that this area of valuation lacks thorough analysis in the Polish market. As a consequence, particularly in the case of lawsuits it may cause unjustified transfers of value between the parties.
