Abstract
Background: The quality of online health-related information may affect users’ understanding and medical decision-making with dramatic impact, particularly in case of stroke. Objective: The objective of this study was to assess the quality of information about stroke on the Romanian and Hungarian websites in terms of completeness and accuracy. Methods: The research was designed as an observational cross-sectional study. The sample included 25 Romanian and 25 Hungarian websites presenting information about stroke for the general public. General characteristics such as website ownership, main goal, website genre and medical approach were identified by the evaluators using a predetermined set of common instructions. The completeness and accuracy of the information were assessed by two independent assessors against a quality benchmark. Results: Overall, most of the websites were owned by private commercial companies (42%), had educational goal (66%), were designed as medical web-portals (46%) and had a conventional medicine approach (72%). Mean completeness score was 5.6 points (SD± 1.9) for Romanian sites and 4.1 points (SD ± 2.4) for Hungarian sites (p = 0.017). Mean accuracy score was 6.2 points (SD ± 1.1) for Romanian sites and 7.0 points (SD ± 0.7) for Hungarian sites (p = 0.02). Conclusions: The information about stroke on the Romanian and Hungarian websites had poor quality. Although we found statistically significant differences between the quality scores of the two language sub-samples and two site characteristics associated with significantly higher quality, the practical relevance of these findings for online health information seekers should be interpreted with caution.

Published: September 2018

Abstract
This paper deals with the relationship between grain yield and grain losses during harvest. Measurements were carried out on a combine harvester with axial harvesting device allowing various adjustments to combine harvester parameter settings, such as rotor speed, gap between separator and rotor, fan speed, holes of the upper and lower sieves. Values of harvest losses in combine harvester with custom settings for the given crops were compared with values of losses obtained by a harvester with manufacturer’s recommended settings. This paper observes the losses in grains of spring barley and winter wheat crops. All the measurements made showed lower grain losses when the combine harvester settings were customized. In general, custom settings provided quantitative losses lower by 0.198% than settings recommended by manufacturer.

Published: September 2018

Abstract
The level of technical knowledge and skills of project managers shows a high differentiation, which has an impact on the management of (non)investment projects in the given region, regardless of the sector area such as agriculture, entrepreneurship or services. This paper aims to confirm that the level of technical knowledge and skills of project managers is highly differentiated in the South Moravian Region of the Czech Republic and to identify the knowledge areas that are affected by the ignorance in this region the most. The research has shown that the management knowledge areas most affected by ignorance in the South Moravian Region of the Czech Republic are namely Scope management, Quality management and Communication management. These findings show a high level of differentiation in the knowledge and skills of project managers on the regional level, having direct impact on public and private projects in the given region. Due to this issue, there should be established certain standards for project management, which can be demanded by central authorities.

Published: September 2018

Abstract
The paper deals with biogas yield production from two co-substrates - sorghum silage mixture of corn silage and crushed potatoes combined with mixture of livestock manure and swine slurry - in a semi-continuous digester under mesophilic conditions. This paper aims to evaluate the suitability of alternative substrates for biogas production under biogas plant operational conditions. In the first experiment, biogas yield was 0.159 Nm3 per hour with methane content of 56.96% vol. In the second experiment, biogas yield was 0.18 Nm3 per hour with methane content of 52.95% vol. Experiments confirmed that both substrates are suitable for biogas production under the given conditions.
Statistical Process Control as a Failure Removal Improvement Tool
Authors: Zasadzień Michał , Midor Katarzyna 
Published: September 2018

Abstract
Continuous improvement should be a part of the strategy of every modern company that wishes to meet the requirements posed by the demanding, competitive market. The article presents a concept of applying a tool known from quality engineering, i.e. Shewhart control charts, for the improvement of the maintenance process in a small company providing services for the agricultural and construction industries. The improvement of the process included the reducing of the downtime of belt conveyors due to failures. Using control charts allowed the detection of interferences in the process and defining of their nature. Using other tools such as 5 WHY allowed the identification of the root causes of overly long downtimes and, consequently, formulation and implementation of improvements and preventive measures that were optimal for the organisation. The verification of actions taken has shown their positive impact on the process, which was reflected in the shortening of downtime and, subsequently, streamlining the failure removal process. The paper presents a possibility and validity of utilising quality engineering tools, such as Shewhart’s charts, 5 WHY or Ishikawa diagram, for improving the maintenance processes.
Interplanetary External Driven Quasidynamo as the Origin of Geomagnetic Jerks Correlated with Length of Day and Gravity Anomaly
Authors: Lutephy Mohsen 
Published: September 2018

Abstract
We report phenomenological inevitable correlation between the Sun’s magnetic field oscillation through the Earth and the Jupiter, with sinusoidal geomagnetic jerks observed at the Earth, additionally aligned with the gravity and length of day sinusoidal variations and we observe too that the Sun and Jovian planets alignments with Jupiter are origin of the observable abrupt geomagnetic jerks whether historical or new, and experimental results demonstrate a possible explanation on the base of the planetary induced currents upon the metallic liquid cores of the planets upon the varying external magnetic fields as the source of heat flows continued by frictional turbulent and convectional fluid fluxes, amplified and expanding by the Earth magnetic field and observations are showing too that it should be an electric coupling effect between metallic cores of the planets, under the magnetic field oscillation so that Jupiter conductive metallic region interacts with Earth metallic core while the Sun’s magnetic field is oscillating through the Jupiter and we see a relation between secular variation of the Earth’s magnetic field and long term trend of 5.9-years signals as a new method to measure geomagnetic secular variation by LOD signals.
Ithyoclinostomum dimorphum Diesing, 1850 (Digenea, Clinostomidae) in Hoplias malabaricus (Erythrinidae) with the fi rst report of infection of the eyes
Authors: Chagas De Souza D. , Lima Correa L. , Tavares-Dias M. 
Published: September 2018

Abstract
The present study investigated the occurrence of metacercariae of Ithyoclinostomum dimorphum in Hoplias malabaricus in the basin of the São Francisco River in the state of Minas Gerais (Brazil). Twenty-nine fish were examined in June 2012 during a survey of fish and parasitic fauna. Of the fish examined, 34.5 % had infected eyes, intestine and musculature, with a mean intensity of 1.1 and an abundance of 0.4 per fish. The prevalence in the intestine was 31.0 %, with mean intensity of 1.1 and mean abundance of 0.3. In the eyes, the prevalence was 3.4 %, with a mean intensity of 1.0 and mean abundance of 1.0. The metacercaria found in the right eyeball was lodged between the cornea and iris. The low parasitism did not affect the condition factor (Kn) of the parasitized fish. This was the first report of I. dimorphum in the eyes of Hoplias malabaricus, a secondary intermediate host for this endoparasite.
Constitutions, Citizenship and the Challenge of National Integration and Nation-Building in Africa
Authors: Mbaku John Mukum 
Published: September 2018

Summary
Most countries in Africa are both “multination” and “polyethnic” states. This is due partly to the forced amalgamation, by the European colonialists, of the continent’s “ethnocultural nations” into single economic and political units that were called “colonies.” These colonies eventually evolved into what are today’s independent African countries. Today, many of these ethnocultural groups want to secede and form their own independent polities in order to have more autonomy over policies that affect their well-being, including especially their cultural and traditional values. The struggle by these groups for either outright secession or so-called enhanced rights has created many challenges for governance, national integration and nation-building in many countries in Africa today. Throughout the continent, inter-ethnic conflict, for example, over the allocation of scarce resources, has produced sectarian violence that has led to civil wars (as occurred in Liberia, Sierra Leone, Rwanda, and Nigeria) and significantly endangered prospects for peaceful coexistence. It has been suggested that the solution to this political quagmire is the creation of differentiated citizenship rights for each of these groups. The paper suggests that of the three types of differentiated citizenship that have been suggested as a way to accommodate diversity—self-government rights, polyethnic rights, and special representation rights—self-government rights pose the greatest threat to social, political, and economic stability in the African countries. The solution to this governance challenge may lie in inclusive and robust dialogue, which can help these groups find a way to remain citizens of their present polities, while at the same time, retaining their cultural identities.
Vanishing Set-Aside Authority in International Commercial Arbitration
Authors: Chen Meng , Wang Chengzhi 
Published: September 2018

Summary
Traditional set-aside theory is subject to considerable challenges as a result of an uncompromising trend towards autonomy and internationalism in international arbitration. The silence and ambiguity of international law regarding enforcement of set-aside arbitral awards allow some states to abandon their own set-aside authority or ignore set-aside decisions made by competent courts. This article presents a range of evidence that demonstrates the enforcement of set-aside arbitral awards has become a common phenomenon. This article first introduces robust academic debates regarding set-aside authority. Then this article exposes omission and ambiguity in the legal source, which leads to confusion in enforcement proceedings of set-aside arbitral awards. This article describes and analyses selected cases and practical data in order to summarize the approaches taken by national courts when reviewing foreign set-aside decisions. Finally, this article briefly evaluates the most promising solutions to the contradictory enforcement proceedings of set-aside arbitral awards.
Emergency Measures of Protection in International Arbitration
Authors: Feigerlová Monika 
Published: September 2018

Summary
Numerous arbitration rules were amended over the last five years to include provisions on the so-called emergency arbitration measures. An emergency arbitrator is appointed before the constitution of a full arbitral tribunal and is empowered to grant an interim relief that the applicants could have historically obtained in these urgent situations from ordinary courts only. The article discusses key aspects and challenges of the new institute in the context of both international commercial and investment arbitration.
GPS Investigations under Constitution of Japan – Comparison with the U.S Cases
Authors: Tsuji Yuichiro 
Published: September 2018

Summary
This paper reviews GPS investigations in Japan and the United States. In 2017, the Japanese Supreme Court held that warrantless GPS search was illegal. The case reviewed in this article illustrates the boundary of permissible investigation using advanced technology and highlights the fact that rapidly developing technology challenges legal research. In the 2017 decision discussed in this paper, law enforcement challenged the permissible scope of investigating warrantless GPS searches; a challenge common in other countries, like the U.S. The U.S. Supreme Court has already decided this case in United States v. Jones decision in 2012. Both of Japanese and American decision takes similar reasoning for their decisions.
Interpretation of the Principle of Informing Parties in Polish Administrative Proceeding – Conclusions and Postulates
Authors: Bisztyga Andrzej , Płonka-Bielenin Katarzyna 
Published: September 2018

Summary
The principle of informing parties in the Polish administrative procedure is specified in Article 9 of the Act of 14 June 1960, the Code of Administrative Procedure. Public administration bodies are obliged to duly and comprehensively inform the parties on the factual and legal circumstances that may affect the determination of their rights and obligations being the subject of administrative proceedings. The authorities ensure that the parties and other persons involved in the proceedings do not suffer damage due to ignorance of the law, and for this purpose they provide them with necessary explanations and instructions. In administrative proceedings, not the principle of ignorantia iuris nocet the obligation of the authority, resulting in particular from Articel 9 CAP is to inform the party about the factual and legal circumstances that may affect the determination of rights and obligations that are subject to current or potential behavior. This principle applies in particular to proceedings in the field of social assistance and proceedings in the field of family benefits, where a specific law is shaped in accordance with the activities of the party. It should be assumed that a breach the party‘s information rules is an intrinsic and sufficient reason for repealing the decision, even if it is in accordance with substantive law.

Published: September 2018

AbstractIn order to ensure better availability of water resource to different users, we undertook a dependability study of system for drinking water supply. A real case study was done on the water supply network in the city of El Hadjarin Algeria. We started from the site modelling, which provided a calculation of a Hydraulic Criticality Index (HCI) in order to prioritize the importance of pipes in the network. Once the indices were calculated, a modelling procedure of reliability block diagram was applied. The objective was to study and analyse the existing network to measure the water availability problems and try to provide viable solutions. An action on the structural aspect and hardware may be required in order to ensure better availability of water and make the system more reliable. Spatial modelling is also proposed to be able to monitor different parts of the network where problems may occur.
Hydrochemical assessment of water quality for irrigation: A case study of the wetland complex of Guerbes-Sanhadja, North-East of Algeria

Published: September 2018

AbstractThe wetland complex of Guerbes-Sanhadja (north-eastern Algeria), has experienced in recent years a certain economic expansion, particularly agricultural, about 47% of the useful agricultural area marked by several varieties of crops ranging from market gardening to speculative crops, requiring large quantities of water for irrigation purposes, however the swampy areas are the main sources used for irrigation purposes in this practice. It is therefore necessary for this water to have physicochemical properties adapted to plants, in particular the absence of salinity. This study was done to evaluate the status of the swamps areas quality and its suitability for irrigated agriculture. To achieve this objective, water samples from ten swamps areas water were collected from Guerbes-Sanhadja in February and June of 2016. The water quality of these swamps was estimated from different water quality parameters such as pH and electrical conductivity (EC), the chemical parameters like Na+, K+, Ca2+, HCO3−, SO42−, Cl−, BOD5, NO3−, NO2−, NH4+ and PO43−. Based on the physico-chemical analyses, irrigation quality parameters like sodium absorption ratio (SAR), percent sodium (% Na), residual sodium carbonate (RSC), permeability index (PI), magnesium hazard (MH) were calculated. The results showed that the overall concentration of nitrate was very high. About 60 percent of the swampy areas had suitable water quality for chloride, and they had a concentration below the permissible limit for crop irrigation. From the Richards diagram, it is observed that most of the samples from the study area fall in the good to permissible classes for irrigation purpose.
Estimating the runoff coefficient using the analytic hierarchy process

Published: September 2018

AbstractThe runoff coefficient (RC) is a parameter that is very often used in surface hydrology in order to characterize the drainage capacity of a watershed. The traditional estimate of this coefficient is often made from abacuses based on 2 or 3 parameters to the maximum. In this work, three numerical models are presented. Two models are based on experimental work. The first one is based on three criteria, namely the vegetation cover, the type of soil, and the slope. The second one considers the size of the watershed, the maximum daily rainfall and the type of soil. In practice, it is not easy to estimate the coefficient of runoff by simultaneously considering the influence of several criteria. In order to overcome this problem, a third model is developed and presented; it allows capitalizing the information from the first two models mentioned above. The objective of the present work is to be able to verify the comparability of these criteria and to assess the relative importance of each of them.
Assessment of the impact of climate change on the freshwater availability of Kaduna River basin, Nigeria
Authors: Okafor Gloria C. , Ogbu Kingsley N. 
Published: September 2018

AbstractChanges in runoff trends have caused severe water shortages and ecological problems in agriculture and human well-being in Nigeria. Understanding the long-term (inter-annual to decadal) variations of water availability in river basins is paramount for water resources management and climate change adaptation. Climate change in Northern Nigeria could lead to change of the hydrological cycle and water availability. Moreover, the linkage between climatic changes and streamflow fluctuations is poorly documented in this area. Therefore, this study examined temporal trends in rainfall, temperature and runoff records of Kaduna River basin. Using appropriate statistical tools and participatory survey, trends in streamflow and their linkages with the climate indices were explored to determine their amplifying impacts on water availability and impacts on livelihoods downstream the basin. Analysis indicate variable rainfall trend with significant wet and dry periods. Unlike rainfall, temperature showed annual and seasonal scale statistically increasing trend. Runoff exhibit increasing tendency but only statistically significant on annual scale as investigated with Mann–Kendall trend test. Sen’s estimator values stood in agreement with Mann–Kendall test for all variables. Kendall tau and partial correlation results revealed the influence of climatic variables on runoff. Based on the survey, some of the hydrological implications and current water stress conditions of these fluctuations for the downstream inhabitants were itemized. With increasing risk of climate change and demand for water, we therefore recommend developing adaptive measures in seasonal regime of water availability and future work on modelling of the diverse hydrological characteristics of the entire basin.
Effect of 2014 massive flood on well water qualities: A case study on Kelantan River basin, Malaysia

Published: September 2018

AbstractThe effect of physical and biological qualities of wells after submergence was assessed following December 2014 flood in Kelantan. Studies were carried out on a total of 65 wells from 13 stations around Kelantan River basin in which the wells’ water were sampled for pH, total dissolved solid (TDS), turbidity and microbial contamination. About 95% of the well showed to be contaminated, 7 out of 65 samples (11.1%) showed TDS values >400 μS·cm−1; and 19 samples (29.2%) recorded turbidity beyond 7.0 NTU. Statistical non-parametric tests carried out on independent groups showed that the status of well contamination was neither determined by both degree of submergence nor by the geographical location. Also the physico-chemical parameters are independent of flood inundation. However, TDS and turbidity values changed based on geographical location, at p < 0.05. Well from estuary recorded higher TDS (241.2 μS·cm−1 ±159.5 SD) and turbidity (8.04 NTU ± 6.53 SD) compared to those from inner basin (TDS at 156.3 μS·cm−1± 88.9 SD; turbidity at 2.90 NTU ± 2.46 SD), respectively. The flood water had played significant role in the transmission of existing contaminant, and most of the wells were unsafe for drinking. We concluded that the degree of flood submergence does not necessarily determine the severity of the well contamination in Kelantan, but the existing contamination may exacerbate further the potential risk during post flood period.
