The possibility of performing the function of a logical key by a device based on a waveguide of spin waves containing two channels differing in the thickness of a ferrite film is shown. To switch the key state, the dependence of the type of interference (constructive or destructive) on the output converter common to both channels on the degree of waveguide deformation under the action of an electrically controlled actuator is used.

AbstractThe results of a study of internal optical losses and current injection efficiency in vertical-emitting lasers of a spectral range of 1.55 µm obtained by sintering plates of high-q Bragg reflectors and the active region on the basis of thin strained InGaAs/InAlGaAs quantum wells have been presented. It has been shown that the proposed design of the laser provides a record low level of internal optical losses (less than 6.5 cm^–1) and high efficiency of current injection (more than 90%) at room temperature, which allows the realization of submilliampere threshold currents. As the temperature rises to 85°C, the current injection efficiency drops to 70% due to the thermal emission of charge carriers from the active region, accompanied by an increase in internal optical losses to 9.1 cm^–1 because of an increase in absorption on free carriers and/or intersubband absorption in the valence band.
Спектральная сенсибилизация фото-ЭДС в монокристаллическом кремнии
Authors: Горяев М.А.
Published: June 2019

AbstractThe effect of an organic dye deposited on the surface of a semiconductor on the photo-EMF spectrum in monocrystalline silicon has been studied. Sensitization of the internal photoeffect has been found in the semiconductor in the absorption band of the dye. An optimal concentration of the dye on the semiconductor surface that corresponds to a dye film thickness of 10–15 nm has been determined. The mechanism of sensitization is discussed on the basis of the theory of nonradiative inductive-resonant energy transfer from the dye to the semiconductor.
THE MAIN CLINICAL SYNDROMES ASSOCIATED WITH ACTIVE CRONIC ATIPICAL EPSTEINE-BARR VIRUS INFECTION: CREATED ALGORITHM OF CLINICAL AND LABORATORY DIAGNOSTIC
Authors: Nesterova I. V. , Khalturina E. O.
Published: June 2019

The annual steady increase of the herpesviral infections number in the human population is one of the most important interdisciplinary problems of modern medicine. Clinicians and laboratory diagnostics physicians face difficulties in clinical symptoms assessing, inadequate laboratory diagnostics and difficulties in interpretation of the obtained results. This is connected with a low awareness of atypical chronic active infection symptoms caused in particular by the Epstein-Barr virus (EBV), of the ability to fully diagnose, and of serious consequencescaused by prolonged activity of herpesviruses in the human body. Studies were carried out to determinethe functioning features of the antiviral defense system, as well as defects and disorders in the interferon system in patients suffering from various mono-, mixed herpesvirus infections and bacterial co-infections. The main clinical syndromes associated with these herpetic infections, as well as prevailing nosological forms of concomitant diseases, have been identified. Among the group of patients suffering from mono-herpesvirus infections, the leading position takes the allergic syndrome (55%), while the syndrome of chronic fatigue syndrome (85%) and the infectious syndrome (68%) prevail in the incidence of patients with mixed herpesvirus infections. Extended testing of the antiviral protection main mechanisms state made it possible to identify the most frequent defects in the functioning of antiviral immunity: disturbances in induced production of IFNα and IFNγ, deficiency of cytotoxic T lymphocytes, deficiency of natural killer cells, including EKT, and / or inadequate absence of their activation, neutropenia. The revealed clinical syndromes and functioning features of the antiviral defense system will allow us to further develop the concept of complex, individualized, etio- and immunopathogenetic therapy.

Published: June 2019

The analysis of the dynamics of heart rate and blood pressure components in students of five ethnic groups - Arabic, Indian, African, Latin American and Russian, taking into account the most characteristic types of autonomous regulation of heart rate (HR) with the third moderate predominance of autonomous regulation (MPAR) and the fourth - a pronounced predominance of autonomous regulation (PPAR) HR. A mediocre level of fitness of the cardiovascular system among students: Russian and Arab with MPAR HR at both stages; Indian and Latin American with MPAR and PPAR HR types of regulation of heart rhythm at the 1st stage; African with MPAR HR on the 2nd stage. The rest of the students - a good level of fitness. High vs. normal values of systolic pressure indicate a maladaptive state of groups of Arab and African students at both stages, Indian with the MPAR HR at the second stage. Increased pulse pressure (PP) in Russian students at the second stage with the PPAR HR, among Arabic, Latin American, African students at both stages, notes a decrease in their myocardial functionality against the background of diastolic fatigue and disadaptation to conditions of relative physiological rest. Under conditions of relative physiological rest, the high anti-normal values of systolic blood pressure (SBP) indicated the maladaptive state of groups of Arab and African students at both stages, Indian with MPAR at the 2nd stage. High PD in all subgroups of Arab, African and Latin American students at the 2nd stage with PPAR and at the rest of the groups with MPAR and PPAR HR are objective indicators of myocardial diastolic fatigue, reduction of its functional capabilities and manifestation of maladaptation in conditions of relative physiological rest.
The specificities of the research in the economics’ development of Sevastopol
Authors: Piskun Elena I. , Khokhlov Vladimir V.
Published: June 2019

A comprehensive study of regional processes implies a qualitative analysis of indicators over time, which is necessary not only to identify current trends, but also to make forecasts that are used in the development of regional development strategies and programs. In order to study the development of the city of Sevastopol on the basis of statistical data on the state of the economy in the Ukrainian and Russian periods, as well as determine the possibility of their use for making forecasts, it is necessary to solve the issue of homogeneity of the series of economic indicators. The existing criteria for verifying the homogeneity of data are not applicable to the solution of the issue of compatibility of multidimensional series belonging to different time intervals. The article proposes the use of exploratory factor analysis to solve this problem. However, the lack of statistical data leads to a degeneration of the matrix of pairwise correlations of economic indicators. To obtain estimates of the parameters of the factor model, a generalized inverse matrix is used, which is obtained as a result of a matrix iterative procedure. Exploratory factor models for the Ukrainian and Russian periods of Sevastopol have fundamental differences, and the corresponding multidimensional series cannot be combined for a holistic study of economic processes in the region.
Trends and strategies of labor emigration from Tajikistan to OECD countries
Authors: Rakhmonov Abubakr K. , Manshin Roman V.
Published: June 2019

The article discusses the trends and strategies of labor emigration from Tajikistan to OECD countries. Waves and types of emigration from Tajikistan, adaptation of emigrants from Tajikistan to OECD countries. As well as the migration policy of the OECD countries in relation to immigrants from Tajikistan. Tajik labor migrants are becoming increasingly brighter than the prospect of getting a job not only in the CIS countries, but also in Europe, Asia and North America, where working conditions are better, and wages are much higher than in Russia and Kazakhstan. The OECD countries can rightfully be considered as new directions of Tajik emigration. An important feature of the tendency and strategy of labor emigration as a result of our research would be to note the combination of educational and vocational qualifications, resettlement and seasonal labor, labor migration - mostly unskilled and skilled with retraining and internship of labor migration from Tajikistan. Adaptation of immigrants is accompanied by some difficulties. The main one is job searches, which usually take several months. For the most part, the emigrants of Tajikistan consider Eastern Europe and Greece as countries of temporary residence, their main goal being moving to Western Europe (Austria, Germany, Scandinavian countries, etc.). There are cases of intentional destruction of their passports by Tajik migrants when they move to Germany with subsequent appeal to the authorities under the guise of refugees from Afghanistan, since both Tajiks and Afghans speak Farsi (Dari) to receive refugee status and corresponding benefits in Germany. In the OECD countries, new Tajik communities are being formed, which may become, in the near future, networks of attraction for new migrants from Tajikistan.

Published: June 2019

Introduction. Exogenous lipoid pneumonia (ELP) is caused by inhalation or aspiration of different oily substances of animal, vegetable, or mineral origin. It can be in acute or chronic form. Herein, we report a case of ELP in its chronic form, confirmed in surgical lung biopsy. Case outline. A 47-year-old male locomotive engineer, former smoker, without clinical symptoms, with a history of pneumonia two years previously, was referred to our institution. The operating diagnosis of multifocal subpleural tumors was made based on the chest computed tomography. A surgical lung biopsy confirmed a diagnosis of ELP. Conclusion. Diagnosis of ELP is frequently made after surgical biopsy performed for suspected neoplasm, because of neglecting profesional exposure to mineral oils.

Published: June 2019

Introduction. The implantable device for mechanical support of the left ventricular circulation (LVAD) is widely applied as a therapeutic option for survival and improvement of the quality of life in patients with the end-stage heart failure. The objective of our paper was to present the implantation of the aforementioned device together with the aortic valve replacement in the same procedure. Case outline. The patient was admitted to the hospital during his terminal stage of heart failure, with ejection fraction of 18%. The ergospirometry test showed that the maximum VO2 was 10.1 ml/kg/min. Because the medicament therapy hadn?t provided adequate results, the LVAD device was implanted as a bridge until transplantation. Due to severe aortic insufficiency, the aortic valve was concomitantly replaced with bioprosthesis in order to prevent the negative effect of this valvular disease on pump work and clinical outcome. Conclusion. This case report confirms that LVAD implantation with the correction of a significant aortic insufficiency is a procedure with satisfactory short-term and long-term results.

Published: June 2019

Introduction/Objective. Although effectiveness of atypical antipsychotics in patients with schizophrenia is mostly similar, there are significant differences in adverse effects rate and treatment costs, making comparison of their cost/effectiveness ratios essential for optimal drug choice. The aim of this study was to compare cost/effectiveness of aripiprazole and olanzapine in long-term treatment of schizophrenia. Methods. A four-state, three-month cycle Markov model was built to compare aripiprazole and olanzapine. The model assumed that patients who relapse on treatment with both aripiprazole and olanzapine are further treated with clozapine. The perspective of the National Health Insurance Fund was chosen, and the period covered by the model was 10 years. The model results were obtained after Monte Carlo microsimulation of a sample with 1,000 virtual patients. Both multiple one-way and probabilistic sensitivity analysis was made. Results. After base-case analysis aripiprazole was dominated by olanzapine, as net monetary benefit was negative (-390,341.96 ?} 29,131.53 RSD) and incremental cost/effectiveness ratio (ICER) was above the willingness-to-pay line of one Serbian gross domestic product per capita per quality-adjusted life year (QALY) gained. Multiple one-way and probabilistic sensitivity analysis confirmed results of the base case simulation. Conclusion. Olanzapine has more beneficial cost/effectiveness ratio than aripiprazole for long-term treatment of schizophrenia in Serbian milieu.

Published: June 2019

Introduction/Objective. Presbycusis, elderly hearing loss, is a progressive, bilateral sensoryneural hearing loss characterized by reduced sensitivity of hearing and understanding speech in a noisy environment, thereby impairing communication and inducing anxiety. The objective was to examine the impact of hearing amplification on subjective hearing disability assessment and anxiety in people with presbycusis. Method. Sample consisted of 120 respondents aged 47?85 with presbycusis, 60 subjects with and 60 subjects with no auditory amplification. The standardized Hearing Handicap Inventory for the Elderly and the Spielberger State Trait Anxiety Inventory were used in the study. Results. In subjects with hearing amplification, test/retest has no statistical significance in the STAI and HHIE scales and subscales, except the HHIE-S (p = 0.004) with a lower score on the retest. Respondents in whom hearing amplification was performed during the year was statistically significant in HHIE (p = 0.016), HHIE-S (p = 0.004) and STAI-S (p = 0.029) which speaks of favorable effect of hearing amplification. In the group with no hearing amplification, statistical significance was observed in relation to the HHIE scores (p = 0.002), HHIE-E (p = 0.000), STAI (p = 0.000), STAI-S (p = 0.001) and STAI-T (p = 0.001) and it was noticed that anxiety, loss of emotional contacts, and more pronounced degree of hearing impairment were the result of unassisted hearing rehabilitation. Conclusion. Audiological practice should include tests for assessment of hearing disability and anxiety in order to preserve health in later life.
Krigets fångar och änglar: Svenska hjälparbetare under första världskriget
Authors: Ingmar Oldberg Karl
Published: June 2019

Mycket har skrivits om första världskriget och dess politiker och militärer, inte minst vid jubileerna hundra år efteråt, men mycket mindre om offren, krigsfångarna och hjälparbetarna. Den här boken handlar om det svenska Röda korsets (RK) insatser i Ryssland bland de två miljonerna krigsfångar, främst från Tyskland och Österrike-Ungern, som spreds till läger över hela landet. Eftersom Sverige var neutralt i kriget, vände sig Tyskland och Ryssland 1915 till Sverige för att utväxla och få fram hjälp till sina respektive krigsfångar. Över tusen järnvägsvagnar med förnödenheter gick genom Sverige från Trelleborg till Haparanda för vidaretransport på ryska järnvägar. Inalles 77 svenska delegater arbetade på plats i Ryssland. Många var kvinnor, oftast ur överklassen, som sökte sig ut i arbetslivet som volontärer. De var tysktalande och anklagades ofta lokalt för tyskvänlighet och spioneri, många arresterades och några dödades. Detta blev Sveriges första stora humanitära insats utomlands och inledde en tradition som fortsatt till våra dagar.

The process of learning should be good and right, of course, must be supported by various facilities in addition to the ability of teachers to organize learning. The selection and utilization of teaching aids is one of the important things that must be considered by the teacher so that the learning process can be more meaningful and can achieve the expected goals. In reality some elementary school teachers teaching social studies in the Buleleng sub-district rarely use the aid of teaching aids in their teaching and learning process. This happened because some of the teachers considered that to make an IPS teaching aid was very difficult to do, to use these teaching aids in social studies learning took a relatively long time so the teacher decided to teach without teaching aids. Another reason given is that the cost of making IPS teaching aids costs a lot. Based on this, it is deemed necessary to make training for teachers in making simple IPS teaching aids and use them in learning in elementary schools. The activity was attended by 30 people from the Undiksha FIP PGSD alumni teachers. After the implementation of this activity the teacher is no longer having difficulty making IPS teaching aids and is able to use IPS teaching aids well.
Un diagnóstico de la universidad mexicana en la obra El libro de la universidad imaginada
Authors: Reynoso Jaime Jenaro
Published: June 2019

Una de las tendencias en los estudios dedicados a instituciones educativas como la universidad sostiene que la práctica investigativa tiene sentido si propone soluciones a los problemas detectados. Para este enfoque de investigación, la intervención en el funcionamiento de la institución solo puede realizarse cuando se hace sobre la base de las conclusiones que arrojan los estudios acerca de las condiciones presentes en las que aquellas funcionan; a su vez, la compresión y valoración que se hace del modo en que opera una institución solo puede lograrse después de revisar retrospectivamente el proceso que la llevó al estado en que se diagnostica.

De esa manera, la imaginación y elaboración de propuestas de solución a problemas detectados, en un aspecto o en el conjunto de la universidad, es procedente cuando quienes la ejercitan lo hacen con los vastos saberes que la formación, el estudio y la experiencia profesional les proporcionan. Tal es el caso de Eduardo Ibarra Colado, quien a partir de su experiencia académica ha promovido la escritura a ocho manos de El libro de la universidad imaginada. Hacia una universidad situada entre el buen lugar y ningún lugar, en el cual la colectividad autoral presenta a la universidad mexicana como una institución inoperante y vieja que debe cambiar hacia una propuesta que aparentemente parece utópica, pero cuyos argumentos llevan a pensarla como necesaria. Por ello, los objetivos del presente documento son ofrecer un acercamiento al concepto diagnóstico, describir la trayectoria del iniciador de la idea plasmada en el referido libro y presentar los rasgos de la universidad anquilosada, la cual, según los autores, debe desaparecer.

Published: June 2019

A growing body of literature has given shape and voice to the emerging field of interreligious studies. However, most of related studies have tended to focus on the relations between religious communities in Western countries. The scholars have not given adequately attention to the richness and complexity of the relations among different religious communities in Asian region and possibility of theoretical and practical contributions to interreligious relations. This article seeks to analyzes the interreligious relations among different religious communities in Indonesia based on data generated through interviews with Muslim, Christian and Kaharingan communities in Indonesia. Employing the concept of Third Space, this article focuses on the performance of interreligious relations between Muslims, Christians, and the adherents of local religion of Kaharingan in Kalimantan Tengah province, Indonesia. It explains the the third space issue in the narrative of interfaith relations and the third space in the practice of interreligious relations in the region. This study find that the diverse religious communities in Indonesia practice a peaceful and co-existence life, which is strongly inspired and driven by shared particular social-cultural contexts of rich treasures and precious tradition of cultural heritage in the forms of Indonesian communalism and community spirit. It concludes that the diverse religious communities create “third spaces”, as common grounds between them which are shared at individual, institutional and societal levels.

Use of Earth Observation Images and GIS Techniques for Groundwater Exploration in Hard Rock Terrain
Authors: MOHANA P. , Muthusamy S
Published: June 2019

Prolonged drought and improper maintenance of water resources increased the demands on ground-water supplies resulting are focuses for the need to evaluate ground-water resources in the hard rock terrain. In recent years, Remote-Sensing methods have been increasingly recognized as a means of obtaining crucial geo-scientific data for both regional and site-specific investigations. This work aims to develop and apply integrated methods combining the information obtained by geo-hydrological field mapping and those obtained by analyzing multi-source remotely sensed data in a GIS environment for better understanding the Groundwater condition in hard rock terrain. In this study, digitally enhanced Landsat ETM+ data was used to extract information on geology, geomorphology. Hill-Shading techniques are applied to SRTM DEM data to enhance terrain perspective views and to extract Geomorphological features and morphologically defined structures through the means of lineament analysis. A combination of Spectral information from Landsat ETM+ data plus spatial information from SRTM-DEM data is used to address the groundwater potential of alluvium, colluvium and fractured crystalline rocks in study area. The spatial distribution of groundwater potential zones shows regional patterns related to lithologies, lineaments, drainage systems and landforms. High yielding wells and springs are often related to large lineaments and corresponding structural features such as dykes. The results demonstrate that the integration of remote sensing, GIS, traditional fieldwork and models provide a powerful tool in the assessment and management of water resources and development of groundwater exploration plans.
Revision of the first Carboniferous palaeofloristic locality discovered in Argentina
Authors: Correa Gustavo , Césari Silvia N.
Published: June 2019

The first Carboniferous palaeofloristic locality recognized in Argentina is situated to the south of the Sierra Chica de Zonda in San Juan Province, Argentina. The fossiliferous site known as Retamito or Río del Agua provided plant remains which were studied by the Polish scientist Ladislaus Szajnocha in 1891. Szajnocha proposed an early Carboniferous age for the assemblage and described some species of lycophytes and sphenophytes, and foliage of cordaitalean and probable pteridosperms. Subsequent studies of this outcrop and its palaeontological content have been few, and a new interdisciplinary approach is needed. The succession is interpreted as fluvial-deltaic in origin, with intercalation of shallow marine deposits, which provided diagnostic plant components of the Nothorhacopteris/Botrychiopsis/Ginkgophyllum Biozone of the late Carboniferous in Argentina. Palynological assemblages recovered from the same strata contain bisaccate taeniate pollen and spores (e.g. Striatosporites heyleri) that support an age probably not older than early Moscovian.
Fern spore viability considered in relation to the duration of the Cretaceous-Paleogene (K-Pg) impact winter. A contribution to the discussion
Authors: Berry Keith
Published: June 2019

The Cretaceous-Paleogene (K-Pg) boundary Chicxulub impact is supposed to have produced a nearly decade-long impact winter which resulted in a mass-extinction event among dicot angiosperms but which left pteridophytes comparatively unaffected. Dicot angiosperms subsequently recovered from the soil seed bank following an episode of global deforestation, although this recovery took centuries. Pteridophytes, on the other hand, are supposed to have recovered within months of the impact event, due to the characteristic, short-term viability of fern spores in the soil bank – an interpretation consistent with the assumption that the dominant fern spore at the K-Pg boundary fern spore spike, Cyathidites Couper, was produced by cyatheaceous foliage. At the K-Pg boundary section near Sugarite, New Mexico, however, Cyathidites spores are more likely to have been produced by schizaeaceous foliage, which produces spores capable of germinating after spending about a decade or more in the soil and which already commanded similar depositional settings in western North America during the Maastrichtian. Therefore, the protracted – millennial – timescale for fern dominance in the earliest Danian could be related to the unique ecology of schizaeaceous ferns that recovered from a persistent spore bank in a habitat that they already dominated, presumably by suppressing the colonization of angiosperms.
Understanding a continuous inland aeolian deposition: a closer look into a chronological and sedimentary record of the north-eastern European Sand Belt
Authors: Kalińska Edyta
Published: June 2019

A belt of inland aeolian sand sediments termed the European Sand Belt (ESB) runs throughout Europe, and its western part has gained greater attention, while attention to the eastern part has been limited. Whereas clear aeolian–paleosol sequences that reflect colder–-armer phases are known from its western part, such alternation is practically undetectable in the eastern part. This study combines the available chronological and sedimentary data from the north-eastern part of the ESB, with a special focus on the Baltic State region. Here, aeolian deposition took place between 15.9±1.0 ka and 8.5±0.5 ka, almost instantly following a deglaciation and drainage of paleolakes, and thereafter practically without longer-term stability. Lack of paleosols is likely due to the prevalence of pioneer vegetation, reflecting dry and cold climate conditions, and thus giving limited opportunity for soil development.
Methods to describe the botanical composition of vegetation in grassland research
Authors: Peratoner Giovanni , Pötsch Erich M.
Published: June 2019

In terms of botanical composition, grassland vegetation in experimental plots and field studies can be described by means of different parameters (plant density, cover, frequency or yield proportion). Each parameter describes different features, which under certain circumstances may be correlated one to each other to some extent, but are not fully equivalent. The choice of the parameter to be assessed depends therefore, in first instance, on the specific aim of the investigation. For the assessment of the chosen parameter, many methods are available that differ from each other in terms of subjectivity, precision, effort and requirement for technical equipment. The choice of method depends mainly on the required precision, the affordable effort and on the available resources.
Fuzzy Supervised Multi-Period Time Series Forecasting
Authors: Ilieva Galina
Published: June 2019

The goal of this paper is to propose a new method for fuzzy forecasting of time series with supervised learning and k-order fuzzy relationships. In the training phase based on k previous historical periods, a multidimensional matrix of fuzzy dependencies is constructed. During the test stage, the fitted fuzzy model is run for validating the observations and each output value is predicted by using a fuzzy input vector of k previous intervals. The proposed algorithm is verified by a benchmark dataset for fuzzy time series forecasting. The results obtained are similar or better than those of other fuzzy time series prediction methods. Comparative analysis shows the high potential of the new algorithm as an alternative to fuzzy prediction and reveals some opportunities for its further improvement.
A combination of biochar and regulated deficit irrigation improves tomato fruit quality: A comprehensive quality analysis
Authors: Keabetswe Larona , Shao Guang Cheng , Cui Jintao , Lu Jia , Stimela Tebogo
Published: June 2019

Quality of fresh produce is the most critical issue in the economics of a vegetable enterprise. In order to investigate the effect of biochar amendment and deficit irrigation on tomato fruit quality, experimental research was conducted under a rain shelter in southern China during the 2017 and 2018 growing seasons. The experiment consisted of five treatments. Crops were irrigated to 100% of field water capacity at all growth stages as treatments T1 and T2. The other treatments received 30% less irrigation water than T2 when its soil water content reached 70% of field capacity, and were designated as treatments T3, T4 and T5, applied at the vegetative (stage I), flowering and fruit development (stage II), and fruit ripening (stage III) stages, respectively. Treatment T1 included no biochar, while the other treatments included 10% biochar by weight. The results showed that the total soluble solids (TSS) content, sugar-to-acid ratio (SAR), vitamin C (VC) content, and colour index (CI) increased in the deficit irrigation treatments depending on the phenological stage, the fruit ripening stage in particular. Meanwhile, single fruit weight was significantly (p < 0.05) reduced by water deficit at stages II and III, subsequently affecting the total fruit yield. Biochar improved soil moisture conservation and had a positive effect on fruit quality as evidenced by better single quality attributes (p < 0.05) of T2 over T1. The GRA and TOPSIS appraisal methods were used to conduct the comprehensive quality analysis. Eventually, treatment T5 ranked the best in both seasons, and this was also confirmed by the combinational evaluation method.

The emergence and spread of Quinone outside Inhibitor (QoI) fungicide resistance in the Irish Zymoseptoria tritici population in the early 2000s had immediate impacts on the efficacy of the entire group of fungicides for the control of septoria tritici blotch. As a result, a dramatic reduction in the quantities applied to winter wheat occurred in the following seasons. Even in the absence of these fungicides, the frequency of the resistance allele, G143A in the pathogens mtDNA has remained exceptionally high (>97%), and as such, it can be anticipated that continued poor efficacy of current QoI fungicides will be observed. Amongst the isolates with G143A, differences in sensitivity to the QoI pyraclostrobin were observed in vitro. The addition of the alternative oxidase (AOX) inhibitor salicylhydroxamic acid increased sensitivity in these isolates, suggesting some continued impairment of respiration by the QoI fungicides, albeit weak. Interestingly, amongst those tested, the strains from a site with a high frequency of inserts in the MFS1 transporter gene known to enhance QoI efflux did not exhibit this increase in sensitivity. A total of 19 mtDNA haplotypes were detected amongst the 2017 strain collection. Phylogenetic analysis confirmed the suggestion of a common ancestry of all the haplotypes, even though three of the haplotypes contained at least one sensitive strain.
The interpretative significance of ripple-derived sedimentary structures within an upper Neogene fluvial succession of central Poland

Published: June 2019

Sedimentary structures discussed in the present study are genetically linked to ripples that consist of pure sand or alternating sand and mud layers. All types of ripple-related structures, such as climbing-ripple cross-lamination and heterolithic bedding, i.e., flaser, wavy and lenticular (nodular), have been identified for the first time in fluvial strata that have been characterised previously as commonly massive. These small-scale bedforms, produced by migrating ripples, have been documented in a fluvial channel of late Neogene age in central Poland. The abundance and co-occurrence of the structures discussed and their spatial distribution provide evidence of their formation under very low-energy conditions, when flow velocity changed markedly, but was often significantly less than 0.5 m/s. Therefore, these ripple-derived sedimentary structures are here recognised as typical of channel fills of an anastomosing river.

Grain size analysis is an important sedimentological tool used to unravel hydrodynamic conditions, mode of transportation and deposition of detrital sediments. For the present study, detailed grain size analysis was carried out in order to decipher the palaeodepositional environment of Middle–Upper Jurassic rocks of the Ler Dome (Kachchh, western India), which is further reinforced by facies analysis. Microtextures were identified as grooves, straight steps and V-shaped pits, curved steps and solution pits suggesting the predominance of chemical solution activity. Grain size statistical parameters (Graphic and Moment parameters) were used to document depositional processes, sedimentation mechanisms and conditions of hydrodynamic energy, as well as to discriminate between various depositional environments. The grain size parameters show that most of the sandstones are medium- to coarse-grained, moderately to well sorted, strongly fine skewed to fine skewed and mesokurtic to platykurtic in nature. The abundance of medium- to coarse-grained sandstones indicates fluctuating energy levels of the deposition medium and sediment type of the source area. The bivariate plots show that the samples are mostly grouped, except for some samples that show a scattered trend, which is either due to a mixture of two modes in equal proportion in bimodal sediments or good sorting in unimodal sediments. The linear discriminant function analysis is predominantly indicative of turbidity current deposits under shallow-marine conditions. The C-M plots indicate that the sediments formed mainly by rolling to bottom suspension and rolling condition in a beach subenvironment. Log probability curves show that the mixing between the suspension and saltation populations is related to variable energy conditions.
Desert loess: a selection of relevant topics

In discussions on loess, two types are often demarcated: glacial loess and desert loess. The origin of the idea of desert loess appears to lie with V.A. Obruchev who observed wind-carried silt on the Potanin expedition to Central Asia in 1895. It might be considered that desert loess would be defined as loess associated with deserts but it came to be thought of as loess produced in deserts. This led to some controversy as no mechanism for producing silt particles in deserts was readily available. Bruce Butler in Australia in particular cast doubt on the existence of desert-made loess.

Butler indicated loess-like deposits in Australia which he called Parna; these are very like loess but the silt sized particles are actually clay mineral agglomerates of silt size- formed in dry lake regions.

At the heart of the desert loess discussion is the problem of producing loess material in deserts. It has been suggested that there are no realistic mechanisms for forming large amounts of loess dust but there is a possibility that sand grain impact may produce particle shattering and lead to the formation of quartz silt. This would appear to be a reasonable mechanism for the African deposits of desert loess, but possibly inadequate for the huge deposits in China and Central Asia. The desert loess in China and Central Asia is loess associated with a desert. The material is formed in cold, high country and carried by rivers to the vicinity of deserts. It progresses then from deserts to loess deposit.

Adobe ground may be defined as desert loess. Adobe occurs on the fringe of deserts, notably in the Sahelian region of Africa, and in SW USA. The use of adobe in construction represents the major utilization of desert loess in a social context. More understanding of adobe is required, in particular with respect to the adobe reaction, the low order chemical reaction which provides modest cementitious properties, and can be likened to the pozzolanic reactions in hydrating cement systems.

The location of loess and loess-like ground on the peripheries of deserts is aided by the observation of the nesting sites of bee-eater birds. These birds have a determined preference for loess ground to dig their nesting tunnels; the presence of nest tunnels suggests the occurrence of desert loess, in desert fringe regions.

We seek amalgamation and contrast: ten main topics are considered: words and terms, particles, parna, geotechnical, adobe, people, birds, Africa, Central Asia, Mars. The aim is some large generalizations which will benefit all aspects of desert loess investigation.

In the paper, an attempt was made to answer the following question: what is the maturity level of the Polish companies operating in the agricultural machinery sector within the area of the implementation of quality management principles, methods and tools? In reference to such an outlined purpose, as necessary activities, it was recommended: at the theoretical level – using the reconstruction and interpretation method of the subject literature – to nominate the questions giving opinions on the maturity level in the sphere of the effective implementation of quality management principles, methods and tools; at the design level – to compile a research tool in the form of an assessment sheet that constitutes a result of the literature exploration and discussion among deliberately chosen experts; and at the empirical level – questioning among manufacturers of parts, components and finished agricultural machinery.
Experiencing mobbing at workplace facing psychological gender and occupational burnout
Authors: Góralewska-Słońska Anna
Published: June 2019

The problem of mobbing in the work environment is significant, there are many factors determining mobbing, and its negative effects affect both the employees of the organization and their social environment as well as the work process. The aim of this study is to determine the relationship of experiencing mobbing with psychological gender dimensions and occupational burnout. 180 people participated in the study, a group of respondents consisted of 123 women and 57 men, aged 20 to 57 years. The research process used: Negative Action Questionnaire (NAQ), Psychological Gender Inventory (IPP) and Questionnaire to study behaviours and experiences related to work (AVEM).

In order to analyse the obtained research results, a correlation analysis was performed to check the relationship between experiencing mobbing activities, (1) and the psychological gender and (2) burnout as well as a linear regression analysis to check what predictors of burnout are. The results of statistical analyses revealed that there is no connection between the experience of mobbing and the psychological gender dimension – femininity, while it was noticed that at the level of statistical tendency there is the relationship between the experience of mobbing and the psychological gender dimension – masculinity. Analysing the results obtained, it was noticed that there is a connection between the experience of mobbing and burnout, people experiencing mobbing are at risk of occupational burnout.
