Published: October 2019

A new LC method for tizanidine hydrochloride in tablet dosage form using a charged aerosol detector (CAD) is described. The influence of various parameters on chromatographic system was investigated by factorial designs and Derringer's desirability. Chromatographic conditions were: mobile phase constituted of acetonitrile and ammonium acetate buffer 17 mM (60:40; v/v), column oven at 39 °C and flow rate 0.8 mL.min-1 performed in on Acclaim Trinity P1 column UV at 230 nm. Thus, it was possible to validate a simple method to assay the tizanidine and its counter-ion in three formulations (drug reference, generic and manipulated). Method showed specificity when challenged by forced degradation and excipients. Finally, the method was compared with USP monograph method demonstrating equivalence in assay evaluation.

Baclofen is a muscle relaxant used as a first option to treat spasticity and muscle spasms in patients with spinal cord injuries, which is available in Brazil as 10 mg tablets. The compendia methods employ HPLC by ion pairing that requires the use of specific reagents and column conditioning, increasing the waste generation and the cost of analysis. In this study, an isocratic, simple and stability-indicating HPLC method was validated to assay baclofen tablets. A C-18 column (Luna®, 150 x 4.6 mm, 5μm), mobile phase composed by triethylamine 10 mM pH 7.0, methanol and acetonitrile (80:15:5), flow rate 1 mL/min and detection at 220 nm was used. The baclofen retention time was 6.2 min and the method was linear in the range of 5 – 100 μg.mL-1 (r = 0.9999). Method selectivity was demonstrated by the forced degradation study and simultaneous analysis of baclofen impurity. The method showed accuracy (mean recovery 99.27%) and precision (RSD < 2%). The robustness was evaluated by factorial design, and the method was robust robust regarding the proposed variations. The developed method met the requirement of current guidelines, being indicative of stability and suitable for the determination of baclofen in tablets.
On the damping intensity of the odd Fourier impulse loading the boundary of the periodic composite
Authors: Kula D.
Published: October 2019

Investigated in the paper boundary effect behaviour for a single odd amplitude which loads rectangular boundary of the two-phased periodic composite layer confirms the common view through the prism of the expected strong suppression of the boundary impulses of the physical field near the boundary of the region occupied by the composite. There is no presence of a composite reaction to the boundary loadings mentioned here different than the exponential damping effect. However, the presence in the general equation describing the boundary effect equations the component 2?ssurf pqz?q with the first space derivative responsible for suppression of the solution along the axis Oz should cause not only exponential type of boundary temperature fluctuation damping. This component disappears in principle for the boundary effect analysed for a single impulse.

Description of epidemiological characteristics at time of diagnosis of 3 hematological neoplasms of lymphoid origin in a domestic reference hospital.
Authors: Nambo Lucio María de Jesús
Published: October 2019

Background. Non-Hodgkin mantle cell lymphoma (MCL), chronic lymphocytic leukemia (CLL), and multiple myeloma (MM) have in common that they are neoplasms which originate in B cells, they present in adult patients, and there is no therapeutic option which achieves a definitive cure. In Mexico, there is scant information on the incidence and characteristics of these neoplasms. Objective. The objective of the study was to identify the demographic, clinical characteristics and the most frequently used treatments of patients with diagnosis of MCL, CLL, or MM who received care at a Mexican hospital. Material and methods. Aretrospective study was conducted, analyzing the clinical records of patients with diagnosis of MCL, CLL, or MM who received care at the Siglo XXI National Medical Center Cancer Hospital Hematology Service. Results. 399 patients were included, 214, (54%) men and 185 (46%) women, with median age 60 years (38 to 88). The distribution was 31 (8%) patients with MCL, 21(5%) with CLL, and 347 (87%) with MM. The most common initial clinical manifestation was weight loss in MCL and CLL, and lumbar pain in MM. The median time for a patient to see a doctor was greater in patients with MM than in MCL and CLL(7.2 vs. 5 and 6 months). The common denominator in the 3 neoplasms was that most of the patients were in an advanced stage of the disease at the time of diagnosis.Conclusion.  Most of demographic characteristics of patients included  were similar to those described in the literature; however, the age of patients with myeloma was lower, the time to diagnosis was greater and stage of disease at diagnosis was higher than expected.Keywords.Mantle lymphoma, lymphocytic leukemia, multiple myeloma.
Effects of the European Common Agricultural Policy on Preserving Biodiversity: Farmland Birds in Slovenia
Authors: Slabe-Erker Renata , Ogorevc Marko , Kmecl Primož , Ciglič Rok
Published: October 2019

This paper assesses the effects of agricultural payments on changes in farmland bird diversity in Slovenia. Diversity was measured by Shannon index, while the impacts were estimated with the first-difference estimator on panel data for municipalities with and without special protection areas for birds. The effects of agricultural payments on farmland biodiversity require that the balance of financial instruments be taken into account when the agricultural policy is being drafted. The effects of payments in municipalities with and without special protection areas indicate the need to consider the landscape perspective and adapt schemes to landscape type while preparing the national agricultural policy.
Land-Use Change Related to Topography and Societal Drivers in High-Mountains – A Case Study in the Upper Watershed of the Tergi (Kazbegi Region), Greater Caucasus
Authors: Theissen Tim , Otte Annette , Waldhardt Rainer
Published: October 2019

High mountain ecosystems, with strong topographic and climatic gradients, are fragile and particularly sensitive to changes in land use. The abandonment of historic cultural landscapes has often led to changes in the pattern of land cover and thus, to a shift in the functions of high mountain landscapes, like fresh water supply, productivity or erosion control. In order to understand the effects of land-use change on the land-cover pattern at the local and regional scale, we analyzed and classified the mountainous landscape structure in the Kazbegi region in Georgia, located in the Central Greater Caucasus. For 13 settlements, we determined the land cover as present in 1987 and 2015, and quantified the changes over time to detect land-cover development trends for each settlement. Using a cluster analysis, the study area was analyzed regarding to topography (altitude, aspect, slope) and distance to settlements at the regional scale to gain six groups with separating conditions. Furthermore, each settlement was classified according to topography and land-cover change to obtain site-specific, comparative development trends. Our results show that this Caucasian high-mountain landscape is characterized by open grassland (67%) used as pasture and hay meadow, and natural birch forests (7%) in patches in the upper half of the subalpine belt. Within the settlements but also in their surroundings, field vegetables are cultivated in home gardens (1%). Land-cover change during the observation period mainly affected the cultural grassland with hay meadow abandonment. Moreover, shrubbery and forest expanded considerably on abandoned pastures. We further detected a strong relationship to topography that considerably varied between settlements resulting in specific trends in land-use change. Hay-making and arable land cultivation are focused today on sun-exposed and gentle slopes near the settlements. Shrub encroachment and reforestations were localized on farther distances and mostly on north-exposed slopes. Besides providing basic information about the historic and current land-use and land-cover patterns, our results quantify the landscape change during almost 30 years. A spatio-temporal analysis revealed an understanding of how land-use decisions influence the landscape pattern. In the context of societal development, regional socioeconomic processes, like shifts in the agricultural structure and population outmigration, seem to be societal drivers of changes. Our findings reveal linkages and interrelationships between natural, human-induced environmental and socioeconomic processes within high-mountain socio-ecological systems. Moreover, we suggest that sustainable land-use strategies for spatial development on sub-regional level, especially in marginal high-mountain regions, should consider topography and its influence on land-use change.
The European spruce bark beetle Ips typographus (L.) in wind-damaged stands of the eastern part of the Tatra National Park – the population dynamics pattern remains constant
Authors: Grodzki Wojciech , Fronek Wojciech Gąsienica
Published: October 2019

In March 2017, in the eastern part of the Tatra National Park in Poland, large windthrowns affected the passively and actively protected Norway spruce Picea abies stands. In early 2018, a set of 12 small research plots (20 trees on each plot) was established in the Norway spruce stands next to the windblown area – 6 in the stands under active nature protection (broken and fallen trees processed in 2017), and 6 in the stands under passive nature protection (trees left on the ground). Living trees on the plots were regularly checked during the growing season in order to identify and register the spruces infested by Ips typographus, which were dissected in 2 or 4 half-meter sections. 155 spruces (64%) infested by I. typographus were recorded on all 12 plots: 118 out of 120 (98%) in passive and 37 out of 120 trees (31%) in active protection. Mean infestation density calculated on 128 samples from 47 trees was higher under passive than under active protection (1.23 and 0.92 mating chamber per 1 dm2, respectively). Among 1709 gallery systems, those with 2 maternal galleries prevailed (63.0%); the mean share of females was higher in passive than in active protection zone (63.1 and 59.6% respectively). The mean number of progeny per one female was higher in active than in passive protection zone (20.23 and 19.12 respectively). I. typographus attack on standing trees had lower intensity in the stands previously subjected to the processing and removal of fallen and broken trees, which indicates positive effect of implemented active protection procedures. The parameters describing I. typographus population on attacked trees, as well as low activity of natural enemies, demonstrate its reproduction potential and resulting high risk of a new outbreak, according to the pattern known earlier from the other areas in Poland and Europe.
Ecological and genetic aspects of distribution of the marginal populations of Swiss stone pine (Pinus cembra L.) in Ukrainian Carpathians
Authors: Mohytych Vasyl , Klisz Marcin , Yatsyk Roman , Hayda Yuriy , Sishchuk Mariana
Published: October 2019

Current distributions of Swiss stone pine mostly cover the mountain regions of Europe (Alps and Carpathians). Easternmost distribution of this species is located in western Ukraine. Due to environmental fragmentation in Eastern Carpathians and competition with Norway spruce and other species, marginal populations of Swiss stone pine create isolated island, where other species are not able to cope with harsh conditions. Still, Pinus cembra L. play an important role for soil-formation and soil-protection in high elevations. The evidence of recent reduction in the area of Swiss stone pine raises the question whether the introduction of this species at lower altitudes can be successful? According to the studies conducted on reciprocal transplant experiments, Swiss stone pine population from higher elevation are able to profit in low elevation sites. Thus, parallelly with gene conservation activity, the possibilities of assisted migration should be recognized for this species.
Europeanisation effects in the court jurisprudence
Authors: Gombos Katalin
Published: October 2019

Nowadays, the notion of Europeanisation, which has formerly been used as a description for multi-level governance, prevails also in the area of law. Legal Europeanisation is a process that appears in the interactions of legal systems of the Member States between one another, as well as between European law and the laws of the Member States. Its main area is the appearance of European legal elements in the legal practice of Member States. At some point, the court practice of Member States may affect European law, as well. Due to the occurrence of comparative law elements, interactions can be observed between courts in the EU. According to our basic premise, the interactions can be best observed through the practice of different courts. This article aims to prove this premise by establishing different guiding principles through further Hungarian court decisions in the field of civil law.

The article specifically considers two basic ideas on the issue at hand: one is slightly critical (Karabelnikov) while the second is rather optimistic in regard with the recent development (Zykov). The main goal is to introduce the issue to the respective readers and to try to inflame a discussion.
Information needs of Trade Fair Visitors — A Survey of the Participants of Kompozyt-Expo 2018 and Fastener Poland
Authors: Proszowska Anita
Published: October 2019

The article presents the results of surveys concerning the information needs of people visiting trade fairs and the conditions for satisfying these needs on the example of the participants of KOMPOZYT-EXPO 2018 and FASTENER POLAND. The results of the surveys are preceded by an overview of literature describing the behaviours of people visiting trade fairs.

The surveys were conducted during the aforementioned fairs by means of a direct questionnaire. On the basis of 98 cases qualified for analysis it was concluded, among others, that visitors during fairs look mainly for information about novelties in a given branch, about the current situation of the branch. They also look for information of an educational character. Moreover, over a half of respondents declared that they don’t prepare for participation in fairs in any specific way and when they plan the sequence of visits to particular stands, they follow mainly the invitations from exhibitors (over 54%). Summing up their presence at fairs over 30% of respondents don’t use special indicators of assessment.

The described surveys, due to small size of the sample, are preliminary in character and refer to a narrow branch represented by respondents, that’s why verification based on a bigger group of respondents and representatives of other branches is required.

Published: October 2019

The present research is focused on developing ZnAl2O4 (gahnite) spinel as an antireflection coating material for enhanced energy conversion of polycrystalline silicon solar cells (PSSC). ZnAl2O4 has been synthesized using dual precursors, namely aluminum nitrate nonahydrate and zinc nitrate hexahydrate in ethanol media. Diethanolamine has been used as a sol stabilizer in sol-gel process for ZnAl2O4 nanosheet fabrication. ZnAl2O4 nanosheet was deposited layer-by-layer (LBL) on PSSC by spin coating method. The effect of ZnAl2O4 coating on the physical, electrical, optical properties and temperature distribution in PSSC was investigated. The synthesized antireflection coating (ARC) material bears gahnite (ZnAl2O4) spinel crystal structure composed of two dimensional (2D) nanosheets. An increase in layer thickness proves the LBL deposition of ARC on the PSSC substrate. The ZnAl2O4 2D nanosheet comprising ARC on the PSSC was tested and it exhibited a maximum of 93 % transmittance, short-circuit photocurrent of 42.364 mA/cm2 and maximum power conversion efficiency (PCE) 23.42 % at a low cell temperature (50.2 °C) for three-layer ARC, while the reference cell exhibited 33.518 mA/cm2, 15.74 % and 59.1 °C, respectively. Based on the results, ZnAl2O4 2D nanosheets have been proven as an appropriate ARC material for increasing the PCE of PSSC.
Fault Prognosis of Hydraulic Pump Based on Bispectrum Entropy and Deep Belief Network
Authors: Li Hongru , Tian Zaike , Yu He , Xu Baohua
Published: October 2019

Fault prognosis plays a key role in the framework of Condition-Based Maintenance (CBM). Limited by the inherent disadvantages, most traditional intelligent algorithms perform not very well in fault prognosis of hydraulic pumps. In order to improve the prediction accuracy, a novel methodology for fault prognosis of hydraulic pump based on the bispectrum entropy and the deep belief network is proposed in this paper. Firstly, the bispectrum features of vibration signals are analyzed, and a bispectrum entropy method based on energy distribution is proposed to extract the effective feature for prognostics. Then, the Deep Belief Network (DBN) model based on the Restrict Boltzmann Machine (RBM) is proposed as the prognostics model. For the purpose of accurately predicting the trends and the random fluctuations during the performance degradation of the hydraulic pump, the Quantum Particle Swarm Optimization (QPSO) is introduced to search for the optimal value of initial parameters of the network. Finally, analysis of the hydraulic pump degradation experiment demonstrates that the proposed algorithm has a satisfactory prognostics performance and is feasible to meet the requirements of CBM.
Measurement Techniques for Electromagnetic Shielding Behavior of Braided-Shield Power Cables: An Overview and Comparative Study
Authors: Hu Peng , Zhou Zhongyuan , Li Jinpeng , Zhou Xiang , Sheng Mingjie , Li Peng , Zhou Qi
Published: October 2019

More and more EMC tests have shown that the radiated emission problems of the equipment under test mainly concentrate on the intercon- nected power cables and cable connectors. Measurement of shielding performance is a prerequisite for quantitative and qualitative evaluation of the frequency-dependent characteristic of braided-shield power cables and cable connectors. Due to the asymmetric geometric structures of these cable assemblies, compared with the coaxial and symmetrical communication cables, the commonly used transfer impedance testing methods may not be suitable. In view of this, several improved simple and effective measurement methods, including transfer impedance and shield reduction factor testing methods, were proposed in recent years. These methods, based on the equivalent circuit model of the characteristic parameters, provide good repeatability for the measurement of shielding performance. This paper presents an overview analysis of various measurement techniques for shielding performance of power cables and cable connectors, highlights some of its equivalence principle in measurement setups, and showcases a brief comparison between transfer impedance and shield reduction factor.
Moderation by Researchgate Related to Comments on “Predatory” Publishing Practices
Authors: Tsigaris Panagiotis , Teixeira da Silva Jaime A.
Published: October 2019

The intersection between academia and social media is gradually overlapping. The ability to vent personal and professional discord online, either through blogs or social media, has had both positive and negative consequences on academic communication, with the public and/or in the public domain. ResearchGate (RG) is one of the most popular academic social media sites that allows commenting, either in response to published papers or to questions that are posed on that platform. This paper explores an important aspect of a high-profile, topical and controversial 2017 paper (Derek Pyne; Journal of Scholarly Publishing; DOI: 10.3138/jsp.48.3.137) that had based itself on a flawed blacklist created by Jeffrey Beall. In that paper, unfounded claims were made regarding financial rewards as remuneration schemes at a “small business school” in Canada related to publishing papers in “predatory” journals, i.e., in open access journals that were blacklisted by Beall. Based on those claims, Pyne used RG as a platform to target academics at his research institute. Pyne could have, but did not, use the scholarly platform to engage with his colleagues in an academic debate about his controversial findings, causing personal disrepute on three occasions. Consequently, RG was contacted with a claim of defamation on each occasion. Within hours of each claim, Pyne’s comments were deleted. In early May, RG also erased his social media account. The issue of actualor potential insults in the public domain, such as on blogs, is rarely discussed, much less related to academic social media sites like RG.  This case study, and the issues discussed herein related to social media more broadly, will be useful for academics to better navigate increasingly challenging publishing waters.

Published: October 2019

Although LinkedIn is the world’s largest professional networking site, the research concerningself-presentation on the platform is limited and fragmented. The main goal of the study was to ex-plore the self-presentation of Polish football managers on LinkedIn in four dimensions: completenessand attractiveness of the profile, network-embeddedness, and activity. Using quantitative contentanalysis of managers’ profiles (N=319), the research shows that the managers exploit the potentialof LinkedIn to build their personal professional brand only in a very limited and mostly static way. Inaddition, the self-presentation in LinkedIn is the best among managers working in Polish FootballAssociation, improves with the length of professional experience, and shows only slight differencesbetween women and men.
Miss Phases of Canadian Federalism
Authors: Evans Michelle Joan
Published: October 2019

A critical review of Simeon and Robinson's "Dynamics of Canadian Federalism." Simeon and Robinson evaluate the evolutionary path of Canadian federalism throughout history using the lens of historical institutionalism. In Simeon and Robinson’s “The Dynamics of Canadian Federalism” in James Bickerton and Alain-G. Gagnon’s Canadian Politics 5th ed., the authors argue that the best way to understand Canadian federalism is by evaluating how key historical factors shaped the application of federal principles. They categorize Canadian federalism into periods and outline what historical factors defined the type of federalism that was pertinent at the time. Canadian federalism has achieved great success in responding to times of international crisis through strong leadership and maintaining the federation despite historical pressures. The question remains, what factors of Canadian politics will inform the next phase of Canadian federalism and how will the Canadian government account for the presence of Indigenous Canadians that have not been considered throughout the evolution of Canadian federalism.

Oil palm (Elaeis guineensis Jacq) is an important crop for Indonesia as one of non fuel export commodities. Development, improvement of quality and productivity of oil palm is influenced by a lot of factors, among others are land characteristics. This research was aimed to know the relationship between oil palm productivity and physical land characteristic including soil, slope and the crop age. The results of this research were expected to be useful to improve oil palm productivity and the oil palm plantation development.This research was done within the site of PT. Perkebunan Nusantara VIII at Cimulang, Bogor. In this research, analyzing correlation between productivity of blocks that have homogenous land characteristic with physical land characteristic parameter including soil and slope. Block with homogenous land characteristic was block which 75% or more of it’s area had similar characteristics. These blocks were determined by overlying block map, slope map and soil map. The result show that were 20 homogenous blocks out of all the 38 blocks of the site the PT. Perkebunan Nusantara VIII at Cimulang. Average production was depend on crop age. At study areas, the highest average fresh fruit bunch production obtained from plants 5 years, which was equal to 22.87 tons acre-1 year-1 and the lowest average fresh fruit bunch production obtained from plants 3 years, which was equal to 0.66 tons acre-1 year-1.  Based on soil, the highest average fresh fruit bunch production obtained from the SPT 11 (Typic Eutrudox), which was equal to 12.54 tons/acre/year and the lowest average fresh fruit bunch production obtained from SPT 1 (Oxic Dystropept), which was equal to 9.51 tons/acre/year. Based on slope class, the highest average fresh fruit bunch production obtained from block with slope class B (8-15%), which was equal to 12.54 tons/acre/year, and the lowest average production was equal to 9.98 tons/acre/year from the slope class.

Encontrando que el contexto social de crianza caracterizado por el abandono estatal y la presencia constante de la guerrilla, facilitó su ingreso a la organización; igualmente, se encuentra la resignificación del rol de mujer, convirtiéndose en un sujeto político e incidente en el cambio social. Así mismo, se indaga sobre la maternidad y la crianza, encontrando mujeres decididas con el cambio social en pro de sus nuevas familias y comprometidas con la lucha desde el escenario político. Finalmente, como retos identificados se encuentra el relativo a la seguridad y los temores con la terminación de los acuerdos pactados, siendo estos, obstáculos para la reintegración social efectiva de las mujeres excombatientes.
