Published: May 2018

Abstract
Introduction. The Internet has enabled an easy method to search through the vast majority of publications and has improved the impact of scholarly journals. However, it can also pose threats to the quality of published articles. New publishers and journals have emerged so-called open-access potential, possible, or probable predatory publishers and journals, and so-called hijacked journals. It was our aim to increase awareness and warn scholars, especially young researchers, how to recognize these journals and how to avoid submission of their papers to these journals.
Methods. Review and critical analysis of the relevant published literature, Internet sources and personal experience, thoughts, and observations of the authors.
Results. The web blog of Jeffrey Beall, University of Colorado, was greatly consulted. Jeffrey Beall is a Denver academic librarian who regularly maintains two lists: the first one, of potential, possible, or probable predatory publishers and the second one, of potential, possible, or probable predatory standalone journals. Aspects related to this topic presented by other authors have been discussed as well.
Conclusion. Academics should bear in mind how to differentiate between trustworthy and reliable journals and predatory ones, considering: publication ethics, peer-review process, international academic standards, indexing and abstracting, preservation in digital repositories, metrics, sustainability, etc.

Published: May 2018

Abstract
Introduction. Reactive stroma co-evolves with prostatic carcinoma. The aim of this study is to establish stromal changes in the prostatic cancer tissue and to quantify those changes.
Methods. Samples from 70 patients treated with radical prostatectomy due to prostatic cancer were used for this analysis. Stromal changes in prostatic cancer tissue were analyzed using histochemical stain Trichrome Masson and immunohistochemical stains Vimentin and Desmin and those changes were compared to the stromal composition in the surrounding benign prostatic hyperplasia. These changes were quantified as following: for the histochemical stain Trichrome Masson we measured the intensity of the stain and for the immunohistochemical stains Vimentin and Desmin we used the “stromal index” that combines the frequency and intensity of the signal. We correlated the received data between each parameters and with tumor grade and tumor stage using the Spearman rank correlation test.
Results. There was significant correlation between Trichrome Masson staining intensity and tumor grade (R=0,27 p=0,023) and tumor stage (R=0,24 p=0,049), between Vimentin expression and tumor grade (R=0,35 p=0,003) and tumor stage (R=0,28 p=0,019) and between Desmin expression and tumor grade (R=−0,25 p=0,035).
Conclusion. Analyses of the stromal composition and the expression of stromal markers in prostatic carcinoma and their quantification could serve as an additional tool in evaluation of tumor aggressiveness and tumor extension.

Published: May 2018

Abstract
Recently, specifically in the last decade, at the University Clinic of Gynecology and Obstetrics, the number of patients treated with epidural analgesia for painless childbirth, which in some percentage ends in Caesarian section (35%), has increased. The increased use of the epidural anesthesia and analgesia is due to the fact that it is one of the most popular ways of childbirth today. This situation is a result of the benefits that epidural anesthesia has for the patient, which consist of allowing the pregnant woman to be conscious during childbirth and to feel and see her child coming into the world, accompanied with smaller intensity of intraoperative and postoperative pain. However, the results or the effects in practice have shown that in certain insignificant percentage patients can have negative consequences from the received analgesia (anesthesia) such as: headache, cases of durra puncture, epidural abscess or hematoma, neurological outbursts etc. But, the subject of this analysis or the aim of this study is the appearance of Horner’s syndrome, as one of the negative effects of the epidural anesthesia, which even though rarely (only in 1% of the cases) can appear as a result of the epidural anesthesia. In the case study using the historic, comparative and empirical method we will try through a specific case to determine the causes for the occurrence of the Horner’s syndrome, how it should be treated and what are the consequences for the patient.

Authors: Duma Filip , Bojadzieva Sonja , Sofijanova Aspazija , Stamatova Ana , Andonovski Angelcho , Jordanova Olivera 
Published: May 2018

Abstract
Tethered spinal cord syndrome is a neurological disorder caused by tissue attachments that limit the movement of the spinal cord within the spinal column. Attachments may occur congenitally at the base of the spinal cord (medullary cone) or they may develop near the site of an injury to the spinal cord. These attachments cause an abnormal stretching of the spinal cord. The course of the disorder is progressive.
We present two patients that were diagnosed at age of three months and three years, respectively. Final diagnosis was made by magnetic resonance imaging, and both patients were referred to University Clinic of Neurosurgery for further treatment.
Our aim is to illustrate the advantages of the early diagnostics of this progressive condition, to present diagnostic methods that are age-dependent and to illustrate the early clinical indicators for its existence.
Economic and Environmental Analysis of Shrimp Farming in Chilika Lake, India
Authors: Lopamudra Mishra 
Published: May 2018

Abstract
The shrimp culture industry around Chilika Lake has expanded in the last two decades under the rationale of providing economic benefits at national, regional, community and household levels. Salinisation and pollution of agricultural land especially rice paddies by seepage usually ruin crops and render the land unsuitable for agriculture. As a result there is the decline in the yield rate, which led to the conversion of agricultural land to shrimp ponds. After the shrimp culture for some years the land will be unable to support any natural or agricultural productivity. In due course, these shrimp ponds are abandoned being fit for nothing. The lack of emphasis on enforcement of different legislation, particularly environmental legislation, has allowed the shrimp farms to operate in and around the lake using culture practices that degrade the environment. Thus, the problem with the state is not a lack of legislation, but an unwillingness or inability to enforce it. As a result of this, an established livelihood system is broken down as land with multiple agricultural uses is turned over to mono-crop production. This in turn will lead to abandoned land, which is of no use after few years.

Published: May 2018

Abstract
The efficiency of exploiting the software takes on new dimensions under the conditions of integrated exploitation at the level of process and structural organization of SMEs found within the regional strategic alliances. The modeling and simulation of the leadership and regulation processes of the supply, sales and production flows imply a complex display of forces between the different partners of the logistic chain which can be supported by the existence of some data bases developed based on information partnership whose purpose is to counterattack the communication barriers and to ensure a flow and flexibility of the entire logistic flow. The modeling and simulation of the non-industrial processes can lead to the increase of the efficient development of the rural areas and small urban areas through agro-tourism, combining elements that are specific to some fields such as agriculture, ecology, merchandise/people transportation and tourism.

Authors: Bogdanov R.V. , Kostiukevych O.M. 
Published: May 2018

Abstract
A computer simulation program for discharge in a magnetron sputtering device with two erosion zones was developed. Basic laws of the graphite target sputtering process and transport of sputtered material to the substrate were taken into account in the Monte Carlo code. The results of computer simulation for radial distributions of density and energy flux of carbon atoms on the substrate (at different values of discharge current and pressure of the working gas) confirmed the possibility of obtaining qualitative homogeneous films using this magnetron sputtering device. Also the discharge modes were determined for this magnetron sputtering device, in which it was possible to obtain such energy and density of carbon atoms fluxes, which were suitable for deposition of carbon films containing carbon nanotubes and other nanoparticles.

Authors: Saleem Muhammad , Iqbal Yaseen , Qin Shan , Wu Xiang , Zhu Feng 
Published: May 2018

Abstract
(La, Nd)2/3TiO3 ceramics were prepared through a conventional solid state mixed oxide route. For phase and microstructure analysis, XRD and SEM were used, respectively. Microwave dielectric properties were measured using a network analyzer. XRD patterns revealed the formation of the parent (La, Nd)2/3TiO3 phase along with (La, Nd)4Ti9O24 as a secondary phase. The microstructure consisted of rectangular and needle shaped grains, which decreased in size from 4 μm to 2 μm with an increase in sintering temperature from 1300 °C to 1350 °C. Decrease in grain size caused an increase in density of the samples from 4.81 g/cm3 to 5.17 g/cm3. Microwave dielectric properties of the samples calcined and sintered in air atmosphere were εr = 40.35, Q × f = 3499 GHz and τf = 0 ppm/°C, whereas for a sample calcined in nitrogen and sintered in air they were εr = 40.18, Q × f = 4077 GHz and τf = +4.9 ppm/°C, respectively.

Published: May 2018

Abstract
The aim of the present work was to study magnetoelectric effect (ME) in (BiFeO3)x-(BaTiO3)1-x solid solutions in terms of technological conditions applied in the samples fabrication process. The rapidly growing interest in these materials is caused by their multiferroic behaviour, i.e. coexistence of both electric and magnetic ordering. It creates possibility for many innovative applications, e.g. in steering the magnetic memory by electric field and vice versa. The investigated samples of various chemical compositions (i.e. x = 0.7, 0.8 and 0.9) were prepared by the solid-state sintering method under three sets of technological conditions differing in the applied temperature and soaking time. Measurements of the magnetoelectric voltage coefficient αME were performed using a dynamic lock-in technique. The highest value of αME was observed for 0.7BiFeO3-0.3BaTiO3 solid solution sintered at the highest temperature (T = 1153 K) after initial electrical poling despite that the soaking time was reduced 10 times in this case.

Abstract
In view of possible practical applications of transparent crystals for mechanical stress sensors, theoretical investigation of piezo(elasto)optic effect in crystals might be useful for searching for proper materials, possessing large coefficients of elasto-optic effect, and for determination of uniaxial stress directions of maximum piezo-optical sensitivity. The influence of the uniaxial stresses on the electronic band structure, density of states, and optical properties of potassium sulphate crystal β-K2SO4 have been studied in the framework of the density functional theory using the ab initio CASTEP code. Increase in the band gap, Eg of the crystal takes place for three crystallographic directions and for moderate uniaxial stresses, σ < 1.5 GPa. Dependencies of principal refractive indices and polarizabilities upon principal uniaxial stresses are discussed together with other features of electronic structure of the crystal.

Published: May 2018

Abstract
Rare earth (RE) ions play an important role in the improvement of the optical properties of ceramics. Rare-earth ceramics are commonly used in display panels, fluorescent lamps and lasers. The luminescence properties of Magnesium Boro-Tellurite (MBT) Eu3+ and Dy3+ doped ceramics have not been reported before. Therefore, the aim of this paper is to determine the effect of different compositions on the luminescence properties of the MBT material. A series of xTeO2-(70-x)B2O3-30MgO ceramics with 10 ≤ x ≤ 40 mol % doped with 1 mol % of Eu3+ and Dy3+ ions was prepared via the solid-state reaction method. The influence of various compositions on the crystalline phase and photoluminescence properties of the samples were investigated by X-ray diffraction (XRD) and luminescence spectroscopy. The crystalline phases obtained in this study are Mg3(BO3)2, MgB4O7, Mg2B2O5, Mg(Te2O5) and MgTe3O6. It was stated that the crystalline phases have not changed as a result of doping with Eu3+ and Dy3+ ions. The emission spectra of Eu3+: MBT ceramics showed strong red emission at 612 nm due to the transition of 5D0 → 7F2 and meanwhile, the Dy3+: MBT ceramics showed a blue emission at 480 nm due to 4F9/2 → 6H15/2 transition and yellow emission at 576 nm due to 4F9/2→6H13/2 transition. Both the rare-earth doped phosphors showed bright emission.

Abstract
In this study, nitrocellulose (NC) fiber blanket prepared by electrostatic spinning method has been used as a template, and copper nitrate (Cu(NO3)2) as an oxidant to synthesise polyaniline nanotubes doped with heteropolyacid (H4SiW12O40, SiW12) using UV light catalytic method. Infrared spectroscopy (IR), X-ray powder diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) technologies were applied to characterize the prepared samples of polyaniline nanotubes. The results show that the external diameter of the tube is about 200 nm, and the internal diameter about 170 nm. We also give a reasonable speculation and explanation about the formation mechanism of the nanotubes.

Published: May 2018

Abstract
In this paper various types of films made of carbon nanotubes (CNTs) are presented. These films were prepared on different substrates (Al2O3, Si n-type) by the two-step method. The two-step method consists of physical vapor deposition step, followed by chemical vapor deposition step (PVD/CVD). Parameters of PVD process were the same for all initial films, while the duration times of the second step - the CVD process, were different (15, 30 min.). Prepared films were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and field emission (FE) measurements. The I-E and F-N characteristics of electron emission were discussed in terms of various forms of CNT films. The value of threshold electric field ranged from few V/μm (for CNT dispersed rarely on the surface of the film deposited on Si) up to ~20 V/μm (for Al2O3 substrate).

Abstract
Mg0:95Ni0:05Ti0:98Zr0:02O3 ceramics was prepared via conventional solid-state mixed-oxide route. The phase, microstructure and microwave dielectric properties of the sintered samples were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM) and a vector network analyzer. The microstructure comprised of circular and elongated plate-like grains. The semi quantitative analysis (EDS) of the circular and elongated grains revealed the existence of Mg0:95Ni0:05T2O5 as a secondary phase along with the parent Mg0:95Ni0:05Ti0:98Zr0:02O3 phase, which was consistent with the XRD findings. In the present study, εr ~17.1, Qufo~195855 ± 2550 GHz and τf ~ -46 ppm/K was achieved for the synthesized Mg0:95Ni0:05Ti0:98Zr0:02O3 ceramics sintered at 1325 °C for 4 h.
Anharmonic phonon properties in Eu0.5Ba0.5TiO3
Authors: Cao Xian-Sheng 
Published: May 2018

Abstract
Phonon properties have been studied using reduced sound velocity of Eu0.5Ba0.5TiO3 (EBTO). To achieve this aim, the anharmonic phonon-phonon interaction and the spin-phonon interaction were used. It was shown that the reduced sound velocity of multiferroic EBTO exhibits a kink at TN = 1.9 K. This anomalously reduced sound velocity can be interpreted as an effect of vanishing magnetic ordering above TN. What’s more, the ferroelectric subsystem cannot be influenced by the magnetic subsystem above TN for TN ≪TC in the EBTO. It was found that the reduced sound velocity decreases as T increases near ferroelectric transition TC. That is to say, the sound velocity softens near ferroelectric transition TC. It is also noteworthy that the reduced sound velocity softens when the RE (the coupling between the ferroelectric pseudo-spins and phonons), V(3) and |V(4)| (the third- and fourth-order atomic force constants of the anharmonic phonons, respectively) increase. These conclusions are all in good accordance with the experimental data and theoretical results.

Abstract
The power output of plasma experiments and fusion reactors is a crucial parameter. It is determined by neutron yields that are proportional and directly related to the fusion yield. The number of emitted neutrons should be known for safety reasons and for neutron budget management. The PF-1000 is the large plasma facility based on the plasma focus phenomenon. PF-1000 is operating in the Institute of Plasma Physics and Laser Microfusion in Warsaw. Neutron yield changes during subsequent pulses, which is immanent part of this type device and so it must be monitored in terms of neutron emission. The reference diagnostic intended for this purpose is the silver activation counter (SAC) used for many years. Our previous studies demonstrated the applicability of radio-yttrium for neutron yield measurements during the deuterium campaign on the PF-1000 facility. The obtained results were compared with data from silver activation counter and shown linear dependence but with some protuberances in local scale. Correlation between results for both neutron monitors was maintained. But the yttrium monitor registered the fast energy neutron that reached measurement apparatus directly from the plasma pinch. Based on the preliminary experiences, the yttrium monitor was designed to automatically register neutron-induced yttrium activity. The MCNP geometrical model of PF-1000 and yttrium monitor were both used for calculation of the activation coefficient for yttrium. The yttrium monitor has been established as the permanent diagnostic for monitoring fusion reactions in the PF-1000 device.
Best Practice of Selecting Strategic International Agency Banking
Authors: Chan Leslie Soon-Lim 
Published: May 2018

Abstract
International agency or correspondent banking (corbanking) is cross border bank to bank businesses that agent banks act on behalf of principals. Despite drastic changing banking environment, corbanking remains from doing business by mainly fee based, packaging reciprocal products and services, and so on. Corbanking is therefore identified as an alternative to serve clients worldwide in a strategic low cost way. Best practice to identify for entering corbanking relationships and selecting their correspondents are the themes of this paper, which are useful for financial institutions to make strategic and operational decisions for their expansion. Eighteen determinant factors to establish corbanking relationships and nineteen selection criteria of correspondents were identified through literature reviews, case studies, and exploratory surveys. Empirical surveys were conducted on 43 sample banks in Australia, which were further categorized in ten bank groups. Analytical methods included descriptive statistics and stepwise least square regression with case studies. The findings were: the most significant factor for financial institutions to enter correspondent banking systems was the bank size and a lower ranking factor was location not physically present, whereas there was different consensus for different bank groups about the selection criteria for agents overseas.
