Authors: Andrusevych Kateryna , Zadorozhnaya Galina
Published: December 2019

The flora of vegetation cover of sod-lithogenic soil on loess loams was studied at a reclaimed site in the Nikopol manganese-ore basin. The control site is located on the black soil of the steppe area. The species composition of plants was studied in both sites annually for three years. Ecological analysis of the flora was carried out according to Raunkiaer’s system of life-forms and Belgard’s system of ecomorphs. It has been established that the floristic composition on the reclaimed site is significantly poorer than that of the steppe site. The reclaimed site was found to be have fewer species and a smaller number of families. The comparative inconstancy and dynamism of floristic composition on reclaimed soil is shown. The reclaimed ecosystem is distinguished by a significant share of the participation of annual and biennial plant forms. This indicates the anthropogenic transformation of the vegetation cover of the reclaimed soil. Also, a distinctive feature of the reclaimed soil flora is the smaller number of ecological groups of species. Such groups are united according to the ecological optimum to one of the environmental parameters.

Authors: Thapamagar Tilak , Bhandari Shivish , Ghimire Kishor , Bhusal Daya Ram
Published: December 2019

The Alpine musk deer (Moschus chrysogaster) is classified as an “Endangered” species by the IUCN Red list category. We studied anthropogenic pressure on the musk deer population in the Khaptad National Park, Nepal. The questionnaire survey was applied from October to November 2018. Out of 111 respondents, 77% reported that the primary objective for poacher kills to the musk deer was musk pod, followed by skin (15%) and meat (8%). The major part of the killing tools represented traps; however, 23% respondents stated that poachers also use snares, 20% respondents reported guns, and 18% persons interviewed had no idea regarding the tool the poachers use to kill the musk deer. There was a significant difference between the male and female respondents regarding their opinion on musk deer conservation; male respondents exhibited more positive attitudes towards musk deer conservation than female respondents (Chi-squared 8.21; P < 0.05). People based conservation awareness programs and alternative income generating sources must be employed for long term musk deer conservation in the Nepal Himalayas.
Periodontal Disease in Association with Systemic Diseases in the Dog
Authors: Penlington L. , Faixová Z.
Published: December 2019

Periodontal disease (PD) is the second most common disease affecting dogs in UK veterinary practices. Veterinary and human literature suggests that periodontal disease may be associated with bacteraemia and a chronic, systemic release of inflammatory mediators which produce direct or immune-mediated changes elsewhere in the body. Thirty canine periodontal patient’s electronic medical histories were analysed for comorbidities. The findings were analysed overall to identify any possible associations. Seventy three percent of these dogs had comorbidities, most commonly haematopoietic, cardiovascular, musculoskeletal and hepatic systems were involved. The most prevalent comorbidities were: high liver enzymes, heart murmur, mitral valve disease, and monocytosis. Other interesting comorbidities were: endocarditis, neutrophilia, submandibular lymph node enlargement and arthritis. Periodontal disease patients had a higher prevalence of disease when compared to the disease prevalence data for UK pet dogs in general. Mitral valve disease was over 17 times more likely in the periodontal disease patients. Comorbidity disease prevalence also increased with more severe periodontal disease stages. This study supports an association between periodontal disease and systemic diseases in the dog. Further studies should focus on confirming a cause and effect relationship. Until then, these data may be useful for veterinarians to examine periodontal patients for concurrent diseases and can be used as a tool to promote dental disease prevention to pet owners.
Antioxidant Enzymes of Honeybee Larvae Exposed to Oxamyl
Authors: Prezenská M. , Sobeková A. , Sabová L.
Published: December 2019

Oxamyl is a carbamate insecticide used to control a broad spectrum of insects. It can also affect non-targeted organisms when applied incorrectly. The world food production depends partially on honeybee pollination abilities and therefore it is directly linked to the health of bees. The success of the colony development depends, among other factors, on the health of the larvae. The first 6 days are crucial for their development. In this stage, the worker larvae grow exponentially and may be exposed to xenobiotics via their diet. In this study, we investigated the effect of oxamyl on honeybee larvae (Apis mellifera) by monitoring the changes in their antioxidant enzyme system. The activities of superoxide dismutase, catalase and glutathione-S-transferase were determined in the homogenates of in vitro reared honeybee larvae after their single dietary exposure to oxamyl at doses of 1.25, 2.5, 5, 10 and 20 µg a.i./larva (a. i.—active ingredient). The doses of oxamyl did not cause statistically significant changes in the activities of the enzymes. Even a slight activation of these enzymes protected the larvae from the adverse effects of the reactive oxygen species (ROS). Marked changes in both the enzyme activity and the content of lipid peroxidation products were observed at the oxamyl dose of 10 µg a. i./larva. This fact may indicate a potential oxidative damage to the larvae. These results allowed us to assume that the toxic effects of oxamyl involves not only the inhibition of acetylcholine esterase but is also associated with ROS production.
Radiocaesium in Honey from Košice and Prešov Regions in Eastern Slovakia
Authors: Beňová K. , Dvořák P. , Špalková M.
Published: December 2019

The activity of radiocaesium was measured in 50 samples of blossom and honeydew honey obtained in the years 2017 and 2018 from beekeepers from various localities of Košice and Prešov regions, eastern Slovakia. The measurements were carried out by gamma spectrometry in Marinelli-type vessels of volume 450 ml without any previous processing of samples. The activity of radiocaesium in honey samples were low, below the detection level of 0.2 Bq.kg−1 in the majority of samples, and was near the levels measured before the Chernobyl disaster. Higher values were detected in honeydew honey compared to the blossom honey. Consumption of honey from the regions presents no risk of exposure to 137Cs.
Detection of Chromosomal Breaks Induced by Thiacloprid in Human Lypmhocytes and Detection of Double-Strand Breaks Based on γH2AX Histone Phosphorylation
Authors: Samková G. , Galdíková M. , Schwarzbacherová V. , Koleničová S.
Published: December 2019

Thiacloprid, a neonicotinoid insecticide, is widely used to control various species of pests in the current agriculture of today. The potential genotoxic effects of thiacloprid on human peripheral blood lymphocytes were investigated in vitro by chromosome aberrations (CA), and double-strand breaks (DSB), which were detected by the phosphorylation of γH2AX histone. Human peripheral blood lymphocytes were exposed to 30, 60, 120, 240, 480 µg.ml−1 doses for the last 24 and 48 hours of culture. Thiacloprid increased CA at the concentrations of 240, 480 μg.ml−1 (P < 0.05), but these results did not confirm genotoxicity. The mitotic index (MI) was important to us; it served as a basis for the confirmation of the cytotoxicity of this insecticide. During 48 hours of culture, at the concentration of 480 µg.ml−1, its value rapidly decreased (0.42) (P < 0.001), which did not allow us to analyse the results because of the high cytotoxic response.
Observation of Seasonal Changes of Selected Hematological Parameters in Trachemys Spp.
Authors: Novoveský E. , Halán M.
Published: December 2019

This study focused on observation of seasonal changes of selected haematological parameters in Trachemys spp. The experiment involved 6 turtles of the same species and approximately the same size. From September 2017 to December 2018 on a monthly basis, the samples of turtle blood were collected and blood smears were made, which were subsequently evaluated by the light microscopy. During the period of observation, we focused on the changes in the percentage of individual types of cells in a leucogram. The most significant differences in the percentage of leukocytes were observed during hibernation and during the summer period. The blood profiles revealed that the most heterophilic granulocytes were most abundant in the summer, when their values reached 50 % of the leukocytes. Significant changes in the percentage of heterophilic and basophilic granulocytes occurred during the period of hibernation. The number of heterocytes during hibernation decreased to 30 %. On the contrary, the number of basophils increased significantly to 33 %. Eosinophilic granulocytes, lymphocytes, and monocytes did not show such notable changes. The results of the study demonstrated that in turtles of the Trachemys genus, changes in their leuco-grams occurred during the period of hibernation. These changes are important for the evaluation of health condition of the turtles, determination of the prognosis and the treatment.
Occurrence of Malassezia Spp. on Healthy Human Skin
Authors: Malinovská Z. , Čonková E. , Váczi P. , Harčárová M. , Böhmová E.
Published: December 2019

The genus Malassezia currently includes seventeen species that have been isolated from healthy and diseased human and other animal skin. Malassezia are implicated in a range of cutaneous diseases in humans: pityriasis versicolor, atopic or seborrheic dermatitis, dandruff, folliculitis and psoriasis. The outbreak of the disease depends on the interaction between the host immune system and Malassezia species. Malassezia stimulates both the cellular and humoral immune response in humans. Although Malassezia species have been associated with various dermatological diseases in people, the detailed pathological role of Malassezia remains obscured. Malassezia yeasts require lipids for their growth and therefore to a greater extent they colonize the sites with more sebaceous glands. The ecosystem on skin is complex and its balance depends on several factors. The aim of this study was to determine the presence of Malassezia yeasts in clinically normal skin of 42 healthy, randomly selected individuals of different ages. In the group of people examined, up to 30 persons (71.4 %) represented by children, adults and the elderly were positive to Malassezia yeasts. It has been shown that the back is an area with a higher incidence (66.7 %) of observed yeast compared to the head (40.5 %).
Optimal Criteria for the Selection of Probiotics, Based on their Mode of Action
Authors: Szabóová R.
Published: December 2019

The objective of this review was to discuss some of the criteria which influence the selection of microorganisms with probiotic properties based on their mode of action. The most common bacteria that belong to the “group” probiotics are the Lactobacillus and Bifidobacterium species/strains. Probiotics have benefits and effects by their mechanism of action in different axial locations such as: producing substances, influencing immune function and response, modification as well as maintenance of a healthy population of microorganisms in the intestinal environment. Probiotics have demonstrated significant potential as therapeutic options for a variety of diseases Potential peripheral pathways that link probiotic ingestion in the brain function are focused on the role of the vagal afferent nerve signalling and changes in the cerebral levels of neuromodulators. The application of probiotic microorganisms represents a way to effectively influence the composition of the intestinal microbiome and the immune system of the host, as well as they can be considered as a suitable alternative to influence a healthy quality of life.
Decompressional equilibration of the Midsund granulite from Otrøy, Western Gneiss Region, Norway
Authors: Holmberg Johanna , Bukała Michał , Jeanneret Pauline , Klonowska Iwona , Majka Jarosław
Published: December 2019

The Western Gneiss Region (WGR) of the Scandinavian Caledonides is an archetypal terrain for high-pressure (HP) and ultrahigh-pressure (UHP) metamorphism. However, the vast majority of lithologies occurring there bear no, or only limited, evidence for HP or UHP metamorphism. The studied Midsund HP granulite occurs on the island of Otrøy, a locality known for the occurrence of the UHP eclogites and mantle-derived, garnet-bearing ultramafics. The Midsund granulite consists of plagioclase, garnet, clinopyroxene, relict phengitic mica, biotite, rutile, quartz, amphibole, ilmenite and titanite, among the most prominent phases. Applied thermodynamic modelling in the NCKFMMnASHT system resulted in a pressure–temperature (P–T) pseudosection that provides an intersection of compositional isopleths of XMg (Mg/Mg+Fe) in garnet, albite in plagioclase and XNa (Na/Na+Ca) in clinopyroxene in the stability field of melt + plagioclase + garnet + clinopyroxene + amphibole + ilmenite. The obtained thermodynamic model yields P–T conditions of 1.32–1.45 GPa and 875–970 °C. The relatively high P–T recorded by the Midsund granulite may be explained as an effect of equilibration due to exhumation from HP (presumably UHP) conditions followed by a period of stagnation under HT at lower-to-medium crustal level. The latter seems to be a more widespread phenomenon in the WGR than previously thought and may well explain commonly calculated pressure contrasts between neighboring lithologies in the WGR and other HP–UHP terranes worldwide.
The relation of the seismicity in the eastern part of the Ukrainian Carpathians and the distribution of electrical conductivity in the Earth’s crust
Authors: Kováčiková Svetlana , Logvinov Igor , Tarasov Viktor
Published: December 2019

We present results of a study of the peculiarities of the seismicity and electrical conductivity distribution beneath the Ukrainian Eastern Carpathians. Based on the analysis of seismic data for the years 1999–2016, specific zones of concentration of earthquake sources related to the principal fault systems and their intersections have been distinguished. This paper covers two zones, one linked to the contact of the Outer Carpathians and the Carpathian Foredeep and another one linked to the fault system transverse to the Carpathians strike. Both belts of earthquake sources concentration correlate well with the geoelectric models of the studied area obtained as a result of 2D and quasi-3D inversion. Most of the seismic events occur at the intersection of the mentioned seismic zones, at shallower depths, than the main conductive structures appear, concentrated at their marginal parts. The interrelation of both phenomena suggests their common explanation by processes occurring in active fault systems: fracturing, shear deformation, migration of highly mineralized fluids, high porous pressure, accumulation and release of tectonic stress.
Th–U–total Pb monazite geochronology records Ordovician (444 Ma) metamorphism/partial melting and Silurian (419 Ma) thrusting in the Kåfjord Nappe, Norwegian Arctic Caledonides

Published: December 2019

The northern extent of the Scandinavian Caledonides includes the Skibotn Nappe Complex of still debated structural position. This paper is focused on part of this complex and presents new U–Th–total Pb monazite dating results for the migmatitic gneiss of the Kåfjord Nappe. The rocks show mineral assemblage of garnet + plagioclase + biotite + white mica + kyanite + rutile ± K-feldspar ± sillimanite. Thermodynamic modelling suggests that garnet was stable at P–T conditions of ca. 680–720 °C and 8–10 kbars in the stability field of kyanite and the rocks underwent partial melting during exhumation following a clockwise P–T path. This episode is dated to 444 ± 12 Ma using chemical Th–U–total Pb dating of the Y-depleted monazite core. Second episode highlighted by growth of secondary white mica resulted from subsequent overprint in amphibolite and greenschist facies. Fluid assisted growth of the Y-enriched monazite rim at 419 ± 8 Ma marks the timing of the nappe emplacement. Age of migmatization and thrusting in the Kåfjord Nappe is similar to the Kalak Nappe Complex, and other units of the Middle Allochthon to the south. Nevertheless, the obtained results do not allow for unambiguous definition of the tectonostratigraphic position of the Skibotn Nappe Complex.
Exhumation history of the Variscan suture: Constrains on the detrital zircon geochronology from Carboniferous–Permian sandstones (Northern Gemericum; Western Carpathians)
Authors: Vozárová Anna , Šarinová Katarína , Laurinc Dušan , Lepekhina Elena , Vozár Jozef , Rodionov Nickolay , Lvov Pavel
Published: December 2019

The Late Paleozoic sedimentary basins in the Northern Gemericum evolved gradually in time and space within the collisional tectonic regime of the Western Carpathian Variscan orogenic belt. The detrital zircon age spectra, obtained from the Mississippian, Pennsylvanian and Permian metasediments, have distinctive age distribution patterns that reflect the tectonic setting of the host sediments. An expressive unimodal zircon distribution, with an age peak at 352 Ma, is shown by the basal Mississippian metasediments. These represent a relic of the convergent trench-slope sedimentary basin fill. In comparison, the Pennsylvanian detrital zircon populations display distinct multimodal distributions, with the main age peaks at 351, 450, 565 Ma and smaller peaks at ~2.0 and ~2.7 Ga. This is consistent with derivation of clastic detritus from the collisional suture into the foreland basin. Similarly, the Permian sedimentary formations exhibit the multimodal distribution of zircon ages, with main peaks at 300, 355 and 475 Ma. The main difference, in comparison with the Pennsylvanian detrital zircon assemblages, is the sporadic occurrence of the Kasimovian– Asselian (306–294 Ma), as well as the Artinskian–Kungurian (280–276 Ma) igneous zircons. The youngest magmatic zircon ages nearly correspond to the syn-sedimentary volcanic activity with the depositional age of the Permian host sediments and clearly indicate the extensional, rift-related setting.
Smart defence: Joint geospatial support in NATO
Authors: Rada Josef
Published: December 2019

Smart defence in NATO may in its very nature represent not only automated remote solutions for battle activities, but harmonized and efficient system of geospatial support of deployed units as well. The objective of this study is to uncover the essence of allied geospatial support mechanism, determine critical spots and propose appropriate system enhancements. Wealth of experience of members of the Armed forces of the Czech Republic was utilized to summarize the state of geospatial support in NATO. It is preferentially experience from foreign operations ISAF and KFOR, cooperation with NATO Headquarters SHAPE and from participation in Multinational Geospatial Support Group. Presented proposals for improvements of geospatial support might have significant impact on intelligence service and military units themselves.

Highlights for public administration, management and planning:

• Multinational Geospatial Support Group will become a single complex executive component of NATO geospatial support for foreign operations.

• Financial and capacity means for geospatial support must be centralized directly within NATO structure to reach maximum efficiency.

• Production of standardized-only scale set maps covering territory of NATO and areas of interest is to be obligatorily for all member nations.

• Access to the web service CoreGIS should be granted for all NATO nations at a national level.
Standardization supporting future smart cities – a case of BIM/GIS and 3D cadastre
Authors: Janečka Karel
Published: December 2019

The aim of the paper is to give an overview of selected ongoing ISO standardization activities in the domain of geographic information dealing with BIM/GIS and 3D cadastre. The presented international standards have also a close relation to the activities (e.g. 3D spatial planning) from which the smart cities could benefit. In particular, in this paper the ISO 19152 Geographic information – Land Administration Domain Model (LADM) standard and ISO 19166 Geographic information – BIM to GIS conceptual mapping (B2GM) standard (still under development) are emphasized. Both mentioned standards are also strongly interrelated with each other. The ISO 19152 standard supports the smart registration of real estates by providing a conceptual schema incorporating 3D parcels, i.e. the 3D cadastre. 3D cadastre can provide the accurate, authoritative and unambiguous foundation for understanding the urban form. The second version of the ISO 19152 is also going to be extended to manage the spatial planning information. This enables 3D spatial planning in connection with the legal information, which is all together of big importance for building the smart cities. Furthermore, the ISO 19166 standard is going to provide a conceptual framework for transformation of BIM into GIS (at various level of details) and vice versa. This enables a wider use of existing detailed and semantically rich 3D digital BIM data in building of the 3D cadastre and smart cities GIS projects.

Highlights for public administration, management and planning:

• There are currently two running projects within International Organization for Standardization (ISO) from which the smart city should benefit – the international standard ISO 19166 BIM2GIS and ISO TR 23262 GIS (geospatial) / BIM interoperability.

• There is an existing international standard ISO 19152 Land Administration Domain Model (LADM) supporting the creation of the 3D cadastre.

• The second version of the international standard ISO 19152, which is now under development, will bring a support for spatial planning and also the examples of technical encodings of LADM in BIM/IFC and CityGML.
Web GIS in mountaineering in Croatia
Authors: Nevistić Zvonimir , Špoljarić Drago
Published: December 2019

Using maps is inevitable in many human activities as well as in mountaineering. Until recently, most of the spatial and attribute data of the mountaineer’s interest could have been found only in analog form. With the development of information technology, global navigation satellite systems (GNSS), easily accessible measuring sensors and digital cameras, it is easier to collect, store, visualize, share, and update spatial data. The web GIS with its associated applications assumes dominance in browsing and dissemination of spatial data, and is applied in areas where there is a need for processing, analysis and visualization of various data that contain a spatial component, including mountaineering. When planning hiking, mountaineers need both spatial and attribute information on mountaineering facilities, checkpoints, and hiking trails in the form of GNSS traces. Through the interactive web application interface, it is possible to connect all these data, enabling easy viewing, browsing and analysis, or performing various spatial queries, which greatly facilitates the planning of hiking excursions. This paper presents a review and comparison of four most visited Croatian mountaineering portals: HPS’s Interactive Mountaineering Map of Croatia, Mountaineering portal and Geodetic mountaineering portal developed at the Faculty of Geodesy of the University of Zagreb and planinarenje.hr portal developed by the group of mountain enthusiasts. Numerous data on Croatian mountains and peaks, mountain facilities, huts and hiking trails are now accessible through portals to anyone with Internet connection, either with the computers, tablets or smartphones. All users can browse, filter and download data from the portal, and there are additional options for authorized users such as commenting on portal content. Several thematic portals of neighboring countries were also analyzed (portal of the Slovenian Mountaineering Association, Slovak mountaineering portal and one Swiss mountaineering portal) and compared with Croatian portals. Finally, the importance of the web GIS portals for the development of mountaineering tourism was emphasized, as well as the ecological culture and the sustainability of the mountaineering environment (preservation of mountain trails and facilities, protection of endemic plants, karst and geological features, etc.).

Highlights for public administration, management and planning:

• The presented web GIS represent an effective and efficient tool for planning and conducting trips in mountain areas as it allows better organization and management of mountain content for the tourists and other hikers.

• Registered users can participate in the portal update (e.g. peak or hill endonyms) and this can be used by State Geodetic Administration for their register of geographical names (http://rgi.dgu.hr/pretrazivanje)

• The Web GIS can also be used as a support in the tourism development of local mountain areas with respect to the ecological culture and sustainability of the mountain environment.
Using artificial neural network for labelling polygon features in topographic maps
Authors: Pokonieczny Krzysztof , Borkowska Sylwia
Published: December 2019

The purpose of this article was to present the methodology which enables automatic map labelling. This topic is particularly important in the context of the ongoing research into the full automation of visualization process of spatial data stored in the currently used topographic databases (e.g. OpenStreetMap, Vector Map Level 2, etc.). To carry out this task, the artificial neural network (multilayer perceptron) was used. The Vector Map Level 2 was used as a test database. The data for neural network learning (the reference label localization) was obtained from the military topographic map at scale 1 : 50 000. In the article, the method of applying artificial neural networks to the map labelling is presented. Detailed research was carried out on the basis of labels from the feature class “built-up area”. The results of the analyses revealed that it is possible to use the artificial intelligence computational methods to automate the process of placing labels on maps. The results showed that 65% of the labels were put on the topographic map in the same place as in the case of the labelling which was done manually by a cartographer. The obtained results can contribute both to the enhancement of the quality of cartographic visualization (e.g. in geoportals) and the partial elimination of the human factor in this process.

Highlights for public administration, management and planning:

• Map label placement is among key variables ensuring the usability of topographic maps across disciplines.

• We present the neural network approach for automating the process of labelling topographic maps with locality names.

• The presented case study applies to the military map in scale 1:50 000, but can be applied on other maps and geoportals.
Parameter recalculation for a rainfall-runoff model with a focus on runoff curve numbers
Authors: Řehánek Tomáš , Podhorányi Michal , Křenek Jan
Published: December 2019

One of the fundamental issues of hydrology is determination of total runoff volume from rainfall. The mutual relationship of these quantities can be experimentally determined by measuring rainfall and runoff. Rainfall-runoff models describe natural relations on the basis of variables determining physio-geographical conditions of a territorial unit as well as hydraulic properties of the respective river network. In the proposed paper, we focused on parameter recalculation of a rainfall-runoff model with focusing on runoff curve numbers (CN). The objective of this study was to update the data (CN) in the old modelling structures within the FLOREON+ (FLOods REcognition on the Net – Study Area) system and replace them with the new ones. The parameters of runoff CN were estimated according to available GIS layers primarily related to the existing soil conditions and land use. In the first phase, the calculation procedure was prepared for the smaller Porubka and Lubina basins, and then it was applied to the whole basin area. The results showed that the new runoff CN recalculation procedure resulted in reduction of the simulated runoff (peak discharge, volume) in the Odra River sub-basins, which also led to approximation to the real measured runoff in the Ostrava-Svinov profile. The derived method is applicable to other basins as well.

Highlights for public administration, management and planning:

• Runoff volumes resulting from rainfall significantly contribute to risk processes, such as soil erosion and floods.

• The partially automated procedure for rainfall-runoff estimation is preseted, based on data for soil conditions and land cover.

• Derivation is based on the original principles determined by the US Soil Conservation Service and can be applied to any river basin in the area of the Czech Republic.

• In the future, the proposed methodology will be adapted to run within the ArcMap application.

Prototype Spatio-temporal Predictive System of pest development of the codling moth, Cydia pomonella, in Kazakhstan
Authors: Afonin A. , Kopzhassarov B. , Milyutina E. , Kazakov E. , Sarbassova A. , Seisenova A.
Published: December 2019

A prototype for pest development stages forecasting is developed in Kazakhstan exploiting data from the geoinformation technologies and using codling moth as a model pest in apples. The basic methodology involved operational thermal map retrieving based on MODIS land surface temperature products and weather stations data, their recalculation into accumulated degree days maps and then into maps of the phases of the codling moth population dynamics. The validation of the predicted dates of the development stages according to the in-situ data gathered in the apple orchards showed a good predictivity of the forecast maps. Predictivity of the prototype can be improved by using daily satellite sensor datasets and their calibration with data received from a network of weather stations installed in the orchards.
Interactive effect of Meloidogyne incognita and Macrophomina phaseolina on the development of root–rot disease complex in relation to growth and physiological attributes of chickpea
Authors: Sumbul A. , Mahmood I.
Published: December 2019

The interactive relationship between the root–knot nematode Meloidogyne incognita and the root-rot fungus Macrophomina phaseolina in a root–rot disease complex of chickpea (Cicer arietinum var. avrodhi) was studied in a net house. The present study was carried out in such a manner so that the pathogenic potential of M. incognita and M. phaseolina individually, simultaneously and sequentially could be monitored. The pathogens singly as well as in combination led to significant reduction in growth, yield, nutrient and biochemical parameters. Gaseous exchange parameters like photosynthetic rate, transpiration rate and stomatal conductance were also reduced following infection of plants by the pathogens. However, maximum reduction was noticed in simultaneous inoculation with both pathogens. Sequential inoculation, where M. incognita preceded M. phaseolina by 15 days, was more damaging to the crop in comparison to that where M. phaseolina preceded M. incognita inoculation by 15 days. Infection by M. phaseolina caused a considerable reduction in the number of galls, egg–masses and nematode multiplication, with the highest reduction observed in plants simultaneously inoculated with the pathogens. Those plants also showed the highest disease severity in terms of percent root–rot. Thus, a manifold action plan to reduce the impact of the root-rot disease complex on chickpea crops has to be formulated.

The mite fauna in foliage and litter of a sprayed alfalfa hay field with the acaricide-insecticide bifenthrin, was studied based on monthly samplings from foliage and litter in Central Greece between 2008–2009. Potential differentiations between this field and two adjacent alfalfa hay fields, which were not subjected to pesticide applications and were managed with different number of cuttings, were also evaluated in terms of population fluctuation over time, population density, species richness, diversity and spatial distribution. The sprayed field hosted 50 and 68 species and morphospecies in foliage and litter respectively, depicting high relative abundance of oribatid and prostigmatic mites. Neoseiulus aristotelisi Papadoulis, Emmanouel and Kapaxidi, was a new record for alfalfa, previously found in rice in Macedonia, Greece. The seasonal fluctuation of mites, particularly in foliage, was similar in all fields. The spatial distribution of a Zygoribatula species, which was common and dominant in all fields, was also aggregated. Finally, the sprayed field shared similar mite diversity with the two non-sprayed fields, but not similar species richness.

Mating disruption (MD) has been a successful approach for pest control of several lepidoptera. Field trials to evaluate the efficacy of communication disruption of low pheromone load formulation on Thaumetopoea pityocampa were carried out in 2010 and 2011 in an urban park. The efficacy of MD was assessed by comparing male T. pityocampa catches in pheromone traps, between MD and Control areas. In the 1st year of the application the percentage of male inhibition ranged from 85 to 100% during the 1st month of the flight period and 95-100% during the whole flight period in the 2nd year. The pheromone remained in the polymeric matrix was almost 30% after 7 weeks under laboratory aging conditions. Combining the pheromone release results with the male disorientation results we can assume that after 7 weeks the remaining pheromone concentration was still sufficient to achieve MD. This study indicates that air permeation with the major sex pheromone component (Z)-13-hexadecen-11-ynyl acetate, at a rate of 20 g/ha for one application per season, can affect the orientation of T. pityocampa males. Since mating disruption is an environmentally safe method for pest control, it could be a valuable tool to control T. pityocampa in urban areas and parks.

Productivity is a significant aspect of construction industry that plays vital role for success and failure of any construction project. This industry generates 11% to 13% of GDP all around the globe and the cost of labour in any building project is 20% to 35% of the cost of Building. On daily basis labour utilizes 30% of time on productive activities rest 70% of the time is ruined in non-productive activities, there are multi factors which are affecting the labour production in construction industry hence this study provides an overview of productivity, Total Factor productivity, method used to measure accurate productivity in construction projects. The objective of this study is find out percentage up to what extent labour production is affected due to weather conditions, however this study is carried out in arid climate region in Month of June 2018, where minimum temperature was recorded 26.0 Celsius degree at 7:30 AM and Maximum was 47.80 Celsius degree at 3:00 PM. A descriptive survey research design approach was adopted using continuous observation method of study. Project work study manual served as the research instrument to collect the data on selected building sites for 30 working days. Data collected were analyzed using descriptive statics. The results show that average monthly production of mason gang was recorded with less production of 28.759%, Carpentry gang with average monthly loss of production 16.74% & steel fixer gang had average monthly loss of production was 12.188. This concludes that prior to signing the contract for construction project. The location, environment, topography of region, capacity of construction operatives must be kept in mind to decide the proper timeline for the successful of project.
Predict of Asphalt Rutting Potential Based on IDT and Validation with ANN
Authors: Divandari Hassan
Published: December 2019

Rutting occurs due to accumulation of incrementally small permanent deformations from each load application and it can cause irreparable problems in pavements. On the other hand, the Marshall Mix design which is known as the main method in Iran, the lack of a simple test to determine specimen resistance to permanent deformation as the major reason for asphalt rutting is noticeable. Although today many devices are used for rutting measurement, none of them have the ability to use in wider field. In addition, prevalent methods of evaluating rutting potential are usually costly and time consuming. Mentioned parameters illustrate the necessity of developing a simple method, not only having fine precision, but also are able to predict rutting performance with low cost in the short term in laboratory. In this research, after performing the main tests on specimens, IDT test results and Marshall Parameters were used to develop a mathematical model to estimate specimen rut depth. The model is validated by using ANN and makes it possible to evaluate mixtures rutting potential while OBC is being determined in laboratory. So not only is there no need to use expensive instruments of rutting test, but also a remarkable time saving in mix design procedure is achievable.

Authors: Javadzadeh P.
Published: December 2019

In recent years, nano technology has been significantly implemented in geotechnical engineering, especially for soil remediation. Using this technology has improved soil resistance parameters and led to the stabilization of many problematic soils. Clay soils, due to their nature, have a large dispersion on the surface of the earth. The widespread dispersion of these types of soils in the site of structures, describes the necessity of studying and investigating new methods of improving and amending the resistive properties of these soils. This research is a review of the use of nanotechnology for the improvement of soil resistive properties by geotechnical researchers.

Authors: Karimi F. , Ranjbaran A. , Amirian P.
Published: December 2019

Fragility curves are useful tools for evaluating the probability of structural damage due to earthquakes as a function of ground motion indices. The force reduction factor (R) is one of the seismic design parameters that determine the nonlinear performance of building structures during strong earthquakes. R factor itself is mostly a function of displacement ductility (µ), natural period of a structure, and soil conditions. A statistical method (Path Analysis) is proposed for the first time to determine the effect of R, µ and T on the column fragility curve parameters of typical box girder, two spans reinforced concrete highway bridge class. An analytical approach was adopted to develop the fragility curves based on numerical simulation. The R, µ and fundamental period T have been used to characterize different bridge configurations. The total, direct, and indirect effects of the variables as having significant effect on fragility curve parameters were identified.
Experimental Study of the Effects of Flow Discharge, Diameter, and Depth on Shear Stress in a Rectangular Channel with Rigid Unsubmerged Vegetation
Authors: Maturi Foad , Behdarvandi Askar Mehdi
Published: December 2019

Shear stress is one of the most critical parameters in hydraulic and coastal engineering, which is often measured indirectly. Since there is no instrument to measure this parameter directly and given that it is usually calculated by measuring other parameters such as velocity and pressure and using some equations, shear stress measurement is often accompanied with large measurement errors. In this study, a new technique and direct measurement using physical modeling in a hydraulic knife-edge flume and load cell were employed to measure the shear stress in a rectangular channel with rigid unsubmerged vegetation with Dv= 20, 25, and 32mm in

Q=25 and 30 Lit/S and y=10, 12, 17, and 20 cm. The results indicate that the shear stress and the dimensionless

ratio decrease in a constant flow discharge with increasing the flow depth. It was also shown that the shear stress would be enhanced with an increase

in vegetation diameter due to increasing vegetation density against flow. According to dimensionless ratios of

Windows and shading devices play a significant role in designing building facades to control the rate of the received daylight and improve visual comfort. This study is aimed to provide an optimization basis for building’s façade considering two variables of Annual Sun Exposure (ASE (1000/250h)) and the view to outside of an office. In this research, the effect of various parameters of shading louvers to the south was investigated in Tehran, Iran. The parameters were number, depth, angle as well as thickness. In this review, Rhino/Grasshopper plug was employed for simulations; moreover, Galapagos evolutionary solver component was used to run the optimization process. This study’s findings showed that it was possible to reach a view of nearly 90% of the interior spaces while the value of ASE (1000/250h) still remained in the reasonable range.
