Size of home range of Tengmalm’s owl (Aegolius funereus) males during breeding season assessed by radio-telemetry in the Jizera Mountains, Czechia
Authors: Kouba Marek , Tomášek Václav
Published: March 2019

Animal home ranges are typically characterized by their size, shape and a given time interval and can be affected by many different biotic and abiotic factors. Understanding of animal movements and assessing the size of their home ranges are essential topics in ecology and necessary for effective species protection, especially concerning birds of prey. Using radio-telemetry (VHF; 2.1 g tail-mounted tags) we studied the movements of two Tengmalm’s owl (Aegolius funereus) males during the breeding season 2008 in a mountain area of Central Europe (the Czech Republic, the Jizera Mountains: 50˚ 50’ N, 15˚ 16’ E). We determined their average nocturnal hunting and diurnal roosting home range sizes. The mean hunting home range size calculated according to the 90% fixed kernel density estimator was 251.1 ± 43.2 ha (± SD). The mean roosting home range size calculated according to the 100% minimum convex polygon method was 57.9 ± 15.8 ha (± SD). The sizes of hunting home ranges during breeding in this study coincide with those previously reported by other studies focusing on Tengmalm’s owl males. However, we found the roosting home ranges were smaller in size compared to those previously reported. This result was most probably connected with different habitat structure in our study area, which was severally damaged by air-pollution in the past, thus probably offering fewer suitable hiding-places, for instance from predators. We found the roosting locations were concentrated in the oldest and densest Norway spruce forest patches. We emphasize that these parts of forest stands require the highest possible protection in our study area.
Influence of terrain attributes on organic carbon stocks distribution in soil toposequences of central Poland
Authors: Kozłowski Michał , Komisarek Jolanta
Published: March 2019

The paper presents the results of research on the relationship between topography of undulated morainic plateau of postglacial landscape and distribution of organic carbon stocks in soil toposequences. The mean value of the soil organic carbon stocks (SOCS) for Retisols/Luvisols (RT/LV) was statistically lower than for the Phaeozems/Gleysols (PH/GL) but for RT/LV a higher variation of SOCS in comparison to PH/GL was observed. On the basis of Pearson correlation coefficient, the cartographic depth to water (DTW), the topographic wetness index (TWI) and the saga wetness index (SWI) were the most strongly correlated with the SOCS from among 13 analysed topographic attributes. In addition, the DTW was more correlated with SOCS than other topographic variables. Moreover, the DTW based on the channel networks with 2 ha flow initiation thresholds better correlate with SOCS than DTW obtained on the basis of channel networks with 1 ha and 4 ha flow initiation thresholds. Using Stepwise multiple regression analysis (SMLR), we concluded that the topographic attributes controlling the soil water content and slope shape had most impact on SOCS of the undulated morainic plateau of agricultural ecosystem. In this landform, where the RT/LV and PH/GL soil sequences dominate, the SOCS can be estimated by the DTW, TWI and GC (general curvature) with an estimation error of 0.21 kg m−2. In view of the increasing availability of LiDAR data and power of GIS tools, the use of topographic metrics to assess spatial variability of soil properties will play an increasingly important role in the estimation of soil properties.
Impact of crop residues and biopreparations on nitrogen changes in Haplic Luvisol – model experiment
Authors: Šimanský Vladimír , Jonczak Jerzy , Kováčik Peter , Bajčan Daniel
Published: March 2019

Agroecosystem crop residues are considered to be a primary resource of organic substances, and are subject to the different transformation processes in the soil environment. The decomposition processes of organic substance can be also regulated by the application of the different biopreparations. The decomposition of organic substances in soil also causes changes in nitrogen content and its forms. It is essential for farmers to know about these processes in order flexibly to regulate and affect the transformation processes of the applied crop residues via the biopreparations directly in the production conditions. The changes of content and forms of nitrogen and its calculated parameters in Haplic Luvisol influenced by the applied crop residues (wheat – WR, rape – RR) and biopreparations (Betaliq, Trichomil) were monitored in the small-pot experiment carried out at the Department of Soil Science (FAFR, SUA-Nitra). The laboratory experiments were established for the incubation period 4, 7, 14, 28, 60, 90 and 180 days. The applied crop residues had statistically significant impact on the contents of total nitrogen (Nt) and potentially mineralizable nitrogen (Npot) and inorganic forms N, similarly also the values of labile nitrogen (LN) and nitrogen pool index (NPI). The biopreparations affected statistically significantly the average values Npot, LN, nitrogen lability index (NLI) and nitrogen management index (NMI). During the incubation period, the contents Npot and values LN and other calculated indexes of nitrogen fluctuated significantly.

Authors: Kamineni Aditya , Duda Sunil Kumar , Chowdary Venkaiah , Prasad C.S.R.K.
Published: March 2019

Compared to homogeneous traffic flow, traffic speed variation is drastic with the involvement of heterogeneity. With an intent of studying the negative upshot of fluctuating speeds of heterogeneous traffic on the environment, the current paper is the outcome of the research done on various highways located in the states of Andhra Pradesh and Telangana in India, with an objective of developing a comprehensive noise prediction model by taking into account the traffic and roadway factors. Quantified noise levels [Leq (dBA) and L10 (dBA)] revealed that for the traffic speed variation of 10 to 95 kmph, the traffic noise levels were significantly affected by the variations in the proportion of the vehicle. On a specific note, the proposed model can be effectively used for the highway traffic noise prediction especially for the heterogeneous traffic, as the difference between the measured and predicted noise levels are within 1 to 10 dB (A).
Measurement of Airport Efficiency. The Case of Colombia
Authors: Olariaga Oscar Díaz , Moreno Luis Pulido
Published: March 2019

Since the mid-1990s, Colombia’s main airports (including those with the highest traffic) have been privatized, transferring governance to private operators. The remaining airports in the network (the smallest ones) continue with public governance. Based on this, the objective of this research article is to know, analyse and even measure the airport efficiency in a context of structural reform and at the same time compare this with the measure in airports with public governance. The methodology used to carry out the study is the Data Envelopment Analysis, and this methodology uses only “technical variables” (that is, only those related to infrastructure). The main results of the research reveal higher efficiency indices in the major (or more important) airports, almost all of them under private governance, although there is also a group of them (usually very small airports) with very low efficiency levels.
Making Temporary Permanent: The Silent Transformation of the Temporary Foreign Worker Program
Authors: Foster Jason
Published: March 2019

During the mid-2000s the number of temporary foreign workers (TFWs) present in Canada increased dramatically, more than tripling in eight years. The bulk of the increase was due to an expansion of the Temporary Foreign Worker Program (TFWP) to include lower-skilled occupations. The stated reason for the expansion was to address short-term labour shortage s. Contrary to expectations, upon the onset of the economic downturn in 2008, the number of TFWs did not decrease significantly, and appears to be increasing again in 2010 and 2011. This paper tracks the evolution of the TFWP from a stable program designed to address short-term labour needs in high-skilled occupations into a broader labour market tool. The paper examines the most recent available statistical data for the TFWP and other documentary evidence to argue the role of the TFWP in Canada’s labour market has quietly shifted, becoming a permanent, large-scale labour pool for many industries, reminiscent of European migrant worker programs. The paper also examines the potential labour market implications of an expanded, entrenched TFWP.
Alliance Building to Create Change: The Women's Movement and the 1982 CUPW Strike
Authors: Nichols Leslie J.
Published: March 2019

Social movements are significant to change mainstream ideologies and values over what is seen to be critical for society. The women’s movement helped to change ideas about women and their roles in society . One significant change, for more universal maternity, only occurred through the alliance with CUPW. This paper will illustrate that the alliance between the women’s movement and CUPW was significant to change public opinion and help to gain paid maternity leave for the majority of working women in Canada. In sum, the power these two groups generated in alliance produced one of the most important social benefits we currently enjoy as Canadian citizens. As a result, alliances are powerful and should be used to further any movement to towards equality.

Authors: Dube Misheck , Phethlo-Thekisho Nomonde
Published: March 2019

This article discusses the psychosocial challenges of widows in the Binga District in Zimbabwe. The feminist and ecological perspectives were used as theoretical frameworks to elucidate the various challenges faced by the widows in the district. Using a qualitative research approach which locates the participants in their cultural contexts and habitants, a phenomenological research design was employed. Aiming at providing a bifocal perspective on the psychosocial plight of widows, samples were drawn from populations of both widows and social service providers. Purposive sampling was used for selecting three categories of participants, namely ten widows for in-depth interviews, two focus group discussants with each group consisting of seven widows, and nine social service providers who were individually interviewed as key informants. Data were thematically analysed with predetermined themes and emerging themes. The results showed that widows in the Binga District were vulnerable and experienced intense psychosocial problems, which need systematic, interconnected, professional and localised social interventions.

Published: March 2019

Pressure fluctuation in single-phase pumps has been studied widely, while less attention has been paid to research on multiphase pumps that are commonly used in the petroleum chemical industry. Therefore, this study investigates the pressure fluctuation for a multiphase rotodynamic pump handling air–water two-phase flow. Simulations based on the Euler two-fluid model were carried out using ANSYS_CFX16.0 at different Inlet Gas Void Fractions (IGVFs) and various flow rate values. Under conditions of IGVF = 0% (pure water) and IGVF = 15%, the accuracy of the numerical method was tested by comparing the experimental data. The results showed that the rotor–stator interaction was still the main generation driver of pressure fluctuation in gas–liquid two-phase pumps. However, the fluctuation near the impeller outlet ascribe to the rotor–stator interaction was weakened by the complex gas–liquid flow. For the different IGVF, the variation trend of fluctuation was similar along the streamwise direction. That is, the fluctuation in the impeller increased before decreasing, while in the guide vane it decreased gradually. Also, the fluctuation in the guide vane was generally greater than for the impeller and the maximum amplitude appeared in the vicinity of guide vane inlet.

Published: March 2019

The effectiveness and performance of industrial hydro-processing Ebullated Bed Reactors (EBRs) are highly dependent on the bed hydrodynamics and operating conditions. In present work, hydrodynamics of EBRs was studied in a cold model experimental setup using air–water–solid particles system. Pressure gradient method and Residence Time Distribution (RTD) technique were used to estimate the individual holdups, and dispersion coefficients in the lab-scale ebullated bed column. System Hydraulic Efficiency (HEF) was also estimated. The results showed that liquid internal recycle ratio, which characterized the EBRs, has a predominant effect on the individual holdups and dispersion coefficients. Empirical correlations were developed for prediction of phase holdups, and dispersion coefficients with good accuracy.
Infinite Dilution Activity Coefficients as Constraints for Force Field Parameterization and Method Development
Authors: Duarte Ramos Matos Guilherme , Calabró Gaetano , Mobley David
Published: March 2019

Molecular simulations begin with an underlying energy model or force field, and from this, can predict diverse physical properties.

However, force fields were often developed with relatively limited datasets, yet accuracy for diverse properties across a broad chemical space is desirable, so tests of such accuracy are particularly important. Here, to this end, we calculate 237 infinite dilution activity coefficients (IDACs), comparing with experimental values from NIST's ThermoML database. We found that calculated IDAC values correlate strongly with experiment (Pearson R of 0.92+/- 0.01), and allow us to identify specific functional groups which appear to present challenges to the force field employed. One potentially valuable aspect of IDACs, as compared to solvation free energies which have been frequently employed as force field tests, is that the same molecules serve both as solutes and solvents in different cases, allowing us to ensure force fields are not overly tuned to one particular environment or solvent.

Published: March 2019

The current financial situation of both domestic and foreign organizations with a developed corporate network has aggravated the problem of building an effective system to manage payments within the group of organizations. It is also necessary to develop a methodology of accounting for and control of payments in corporate systems able to meet the requirements ofinternational practice. The article discusses some evidence confirming the need for ongoing payments and the emergence of liabilities in corporate systems. The authors prove that settlements with contractors are the link that transforms any systemof holding type into a single organism, which makes it possible to develop and build an effective management model for such corporate system, reduce tax risks and cut the costs of its maintenance. In their research the authors use the methods of comparison, grouping and analysis of results of activity of corporations on the issues of redistribution of financial resourceswithin the group and the valuation of liabilities which arise in corporate systems. This results in drawing conclusion about structuring and validity of accounting procedures related to arising, movement of and ending the liabilities in corporate systems. This article intends to stimulate discussion and future research of the problems identified by the research.

Abstract. The inhibition capacity of the angiotensin converting enzyme (ACE) was determined by 5 different methylthiomorpholine compounds: (4-tert-butyl-2-(thiomorpholin-4-ylmethyl)phenol (LQM318), 4-tert-butyl-2,6-bis(thiomorpholin-4-ylmethyl)phenol (LQM319), 3,5-bis(thiomorpholin-4-ylmethyl) pyrogallol (LQM322), 4-methoxy-2-thiomorpholin-4-ylmethyl-1-phenol (LQM328) and 3,6-bis(thiomorpholin-4-ylmethyl)benzene-1,2-diol (LQM329), using Captopril as a reference. This last drug is used as an antihypertensive agent and known for its biological effect over ACE. The study was done using the capillary electrophoresis technique, with an in-line reaction using hippuryl-histidyl-leucine (HHL) as substrate to produce hippuric acid (HA). HA was detected at 254 nm, which is the detection wavelength to get the quantification of this compound. That was performed under the experimental conditions reported for such interaction. From this, the electrophoretic mobility of hippuric acid was computed in order to deduce the effective migration time and the recovered quantity, to prove and quantify the in-line activity of the enzyme. Resumen.

The increasing volcanic activity of Anak Krakatau volcano has raised concerns about a major disaster in the area around the Sunda Strait. The objective of the research is to fuse Landsat-8 OLI (Operational Land Imager) and Sentinel-1 TOPS (Terrain Observation with Progressive Scans), an integration of SAR and optic remote sensing data, in observing the lava flow deposits resulted from Anak Krakatau eruption during the middle 2018 eruption. RGBI and the Brovey transformation were conducted to merge (fuse) the optical and SAR data.  The results showed that optical and SAR data fusion sharpened the appearance of volcano morphology and lava flow deposits. The regions are often constrained by cloud cover and volcanic ash, which occurs at the time of the volcanic eruption.  The RGBI-VV and Brovey RGB-VV methods provide better display quality results in revealing the morphology of volcanic cone and lava deposits. The entire slopes of Anak Krakatau Volcano, with a radius of about 1 km from the crater is an area prone to incandescent lava and pyroclastic falls. The direction of the lava flow has the potential to spread in all directions. The fusion method of optical Landsat-8 and Sentinel-1 SAR data can be used continuously in monitoring the activity of Anak Krakatau volcano and other volcanoes in Indonesia both in cloudy and clear weather conditions.
