Sobre la materialidad del poema épico o cómo la edición no hace al libro: estética y canon en el sistema literario impreso
Authors: García-Minguillán Claudia
Published: October 2020

La renovación del sistema literario surgida a la estela de los movimientos culturales del siglo xviii alteró la estática situación en la que se encontraba el género épico. Al calor del enfrentamiento entre antiguos y modernos, se publican y acompañan nuevas traducciones y ediciones de los clásicos grecolatinos, lo que incita la composición de nuevos poemas épicos y los posteriores debates entorno a la forja de un canon.  En este trabajo proponemos un estudio que aborda la construcción y la estética de este grupo de textos en cuanto a su soporte material: edición, ilustraciones, grabados, colecciones, obras completas.  Se alcanza a observar cómo la concepción física de un libro fomenta la institucionalización o no de un canon literario, junto a una estética reconocible y asimilable por el público.
Censura, economía y literatura
Authors: Carini Sara
Published: October 2020

El presente estudio se propone analizar las dinámicas económicas y de poder que se dan alrededor de la edición analizando el epistolario que mantuvieron Carlos Barral y el agente literario Erich Linder. Estos documentos de archivo atestiguan el interés que ambas editoriales tenían en la traducción de sus respectivas obras a otros idiomas pero, al mismo tiempo, testimonian los problemas que el mundo de la edición española tenía que superar a la hora de conseguir un título o una autorización por parte de la censura y también las consecuencias que estos problemas daban en las relaciones personales y de negocio. El estudio de estos documentos permite esbozar algunas conclusiones interesantes a la hora de tomar en consideración el desarrollo de las literaturas en lengua española en traducción.
Reelaboraciones en el siglo XX de las novelas de Manuel Fernández y González
Authors: Muñoz de Morales Galiana Javier
Published: October 2020

Manuel Fernández y González fue el novelista español más prolífico y vendido del siglo XIX. Autor de casi doscientos títulos conocidos, el auge de la novela por entregas como negocio editorial le permitió gozar de un éxito sin precedentes en la literatura española, si bien en buena medida este formato condicionó por completo sus textos y lastró la calidad literaria de su producción; sus obras muchas veces tuvieron que alargarse excesivamente para contentar las demandas del público y poder resultar más rentables. Un siglo después, en el XX, Fernández y González siguió reeditándose, pero el modelo de la novela por entregas ya no existía; las casas editoriales que quisieron publicar de nuevo sus obras tuvieron que enfrentarse al problema de lo muy condicionados que estaban esos textos por la antigua industria de la entrega. A fin de adaptar esas obras al mercado del momento, los encargados de esas publicaciones tuvieron que acabar modificando sustancialmente el texto original, abreviando por distintas vías lo que originalmente era muy extenso; los cambios introducidos son tantos y tan significativos que nos permitirían hablar de cocreación y reelaboración en torno a un original.
colección de punzones y matrices del obrador de fundición de la Imprenta Real en dos inventarios decimonónicos
Authors: Corbeto L[opez Albert
Published: October 2020

Desde prácticamente la aparición del arte tipográfico los impresores españoles se vieron obligados a trabajar con letrerías realizadas en unos pocos juegos de matrices importados o con tipos adquiridos directamente en fundiciones foráneas. La restauración de las artes del libro que se produjo en España durante la segunda mitad del siglo XVIII propició la especialización de los artesanos más capaces en el grabado con fines tipográficos. Los punzones y matrices producidos por Jerónimo Gil en el obrador de fundición de la Real Biblioteca, en el que se fundieron los tipos que se usaron para imprimir las mejores obras españolas de la Ilustración, pasaron a finales de siglo a la nueva Imprenta Real. Esta colección se fue ampliando a lo largo del XIX con otros materiales, algunos realizados en el país y otros muchos importados de las mejores fundiciones del continente, como las de Bodoni y Didot. En este trabajo se reproducen dos inventarios decimonónicos de dicha colección en los que se ofrecen informaciones de gran interés para conocer su composición hasta el más mínimo detalle.
Emociones y sentido de autoeficacia de los futuros profesores de inglés
Authors: Reyes-Cruz Maria del Rosario
Published: October 2020

El objetivo de este trabajo fue comprender los estados emocionales que experimentan los profesores de inglés en formación a largo de sus prácticas docentes así como sus fuentes de activación; de igual manera se determinó el sentido de autoeficacia docente de los mencionados practicantes y la influencia que en él ejercen sus emociones. Se utilizó un diseño cualitativo exploratorio. Los participantes fueron 10 profesores de inglés en formación. Los hallazgos indican que todos los practicantes experimentaron estados emocionales negativos al inicio de las prácticas y que la activación provenía del hecho de impartir clases. Las creencias de autoeficacia inicialmente eran bajas y aumentaron paulatinamente a lo largo de las prácticas. Las emociones también evolucionaron de negativas a positivas en ese lapso. Las emociones negativas parecen generar creencias de autoeficacia bajas del mismo modo que las positivas generan creencias de autoeficacia altas.
A new sperm selection criterion for cryopreservation of boar semen
Authors: Trzcińska Monika , Bryła Magdalena
Published: October 2020

This study aimed to define potential markers that could determine the suitability of ejaculate for cryopreservation. Fresh semen from eleven boars (4–7 ejaculates/boar), regardless of their sperm motility, was subjected to a cryopreservation procedure. The sperm quality before and after freezing was assessed based on the sperm membrane permeability and acrosome integrity. The results showed that it was possible to effectively cryopreserve ejaculates below the accepted standards of 70–80% of fresh motile sperm and still obtain a high cryosurvival rate. Moreover, a significant correlation was found between the percentage of viable sperm with apoptotic-like changes, viable sperm with reacted acrosomes, and the cryosurvival rate. The proposed markers for assessing the quality of fresh semen could be used to predict the success of cryopreservation procedures.
Explore the Lessee Accounting Treatment When Utilizing the Islamic Financial Leasing
Authors: Morshed Amer , Széles Zsuzsanna
Published: October 2020

This study aims to discuss the effects of the AAIOFI accounting standards of financial leased assets on the accounting treatment of the lessee in the case of using the Islamic finance lease. The importance of this study became evident when AAIOFI announced Islamic accounting standards with a significant difference between the IFRSs about the recognition of leased financial assets. Islamic financial institutions recognize the financial leased assets following AAIOFI accounting under long-term assets in the statement of financial position. This study used the interviews as a qualitative research method with financial managers of Jordanian companies using Islamic financial leasing. This study reached the conclusion that both Islamic financial leasing parties recognize the assets in the long-term asset side. The recommendations to avoid the inflation of the Islamic financial leased assets will be by applying a reasonable accountancy treatment by the lessee and consider it as operational leasing with proper justification for the non-compliance with the IFRS.

Determination of Sewing Thread Consumption for 602, 605, and 607 Cover Stitches Using Geometrical and Multi-Linear Regression Models
Authors: Sarah Malek , Boubaker Jaouachi , Dominique Adolphe Charles
Published: October 2020

This work deals with prediction of the quantities of sewing threads required to sew a garment using cover stitches for the different classes of 600 (602, 605 and 607 cover stitches) by performing a rapid and precise methods (Geometrical and statistical). Sewing consumption value was estimated based on the geometrical method of different cover stitch shapes to prevent inventory of stocks for each stitch type. In the prediction of the sewing thread consumption for each investigated stitch, it was assumed that the consumption is a function of the input parameters, such as material thickness, stitch density, yarn linear density, and seam width. In addition, a statistical method based on multi-linear regression was established. The coefficient R2 value was determined to evaluate the precision of the geometrical and statistical methods. By comparing the theoretical thread consumption with the experimental ones, it is concluded that the geometrical method is more accurate than the statistical method regarding the range of R2 (from 98.78% to 99.38%), which encouraged industrialists to use geometrical models to predict thread consumption.

The input parameters contributing to the sewing thread consumption behavior were studied and analyzed. It was concluded that the most important parameters influencing thread consumption are stitch density followed by seam width. Both yarn density and material thickness have a low contribution to the thread consumption value.

Authors: Kowalski Krzysztof , Kłonowska Magdalena , Sujka Witold , Latańska Ilona , Kowalski Tomasz Marek
Published: October 2020

This article presents a useful algorithm for designing compression products with intended and graded unit pressure along the part of the body covered with the mentioned garments. The algorithm was developed using Laplace's law and a designated experimental function describing the relationship between strength and relative elongation of knitted fabric, and the results of 3D scanning of different body parts. On this basis, two examples of products in the form of a leg sleeve and arm sleeve were designed for the treatment of lymphoedema in compression classes II and III. The presented compression product design procedure facilitates the process of designing compression garments and eliminates some errors related to this procedure.

Authors: Klimek-Kopyra Agnieszka , Neugschwandtner Reinhard W. , Gląb Tomasz , Oleksy Andrzej , Zając Tadeusz
Published: October 2020

Ecological intensification of crop production involves the use of intercrops and the rational use of inoculation and fertilization in case of intercrops including legume species. The root system plays an important role in the productivity of crops. Therefore, effects of the inoculation treatments (Nitragina) or foliar fertilization (Photrel) or a combination of both were assessed on root parameters of pea grown as pure stand or intercrops with linseed or wheat in a 3-year experiment in Poland. Crop stand composition influenced the root parameters of pea with a higher root length density (RLD) in the root fractions of 0.1–1 mm of pea in pea/linseed intercrops than in the pure stand, a higher mean root diameter (MRD) in pure pea and intercrops of pea with linseed than with wheat, and also a tendency of a higher root dry matter (RDM) in pure pea and pea/linseed than in pea/wheat in 2 out of the 3 years. RLD was higher with Photrel than with Nitragina in root fractions of 0.1–0.5 mm. Treatments did not affect the MRD, but a combination of Nitragina + Photrel increased the RDM in 1 year. Intercropping of pea with linseed and the application of a foliar fertilizer might be a strategy to improve pea root characteristics.
Effect of the Glycemic Index of Meals on Physical Exercise: A Case Report
Authors: Biagini Andrea , Albi Elisabetta
Published: October 2020

Carbohydrate uptake before physical exercise allows to maintain plasma glucose concentration. Though, foods or beverages containing the same carbohydrate concentration do not produce the same glycemic and insulin responses which are related to their glycemic index (GI). Last, most studies of CHO loading have been conducted with male subjects, with the assumption that the results also apply to female athletes.

Sixteen volunteer amateur athletes, eight men and eight women (age 39.1 ± 7.8 y; VO2max 55,7 ± 11,7 ml/kg/min), were selected and then divided into four groups of four people each one. The trial was divided into several days, one for each group. A carbohydrate source or a placebo (energy 86,5 ± 6,7 kcal; CHO 20,0 g; fat 0,3 ± 0,3 g; protein 0,8 ± 0,8 g) was assigned randomly to each athlete in the group: these supplements differed in the ability to increase blood glucose (banana: high-GI; dried apricots: low-GI; energy gel: mixture of CHO with different blood release), while the placebo was composed of water, sodium cyclamate, sodium saccharin and acesulfame potassium. Three blood samples were taken from each athlete from finger, by glucometer: one before supplementation, one half an hour later – at the start of the run – and one at the end of the exercise.

Physical activity consisted of 40 minutes run at medium-high intensity, corresponding to 82% of maximum heart rate or 70% of VO2max. In order to improve the analysis of the results obtained from the detection of biological samples, a questionnaire was submitted to all participants to know their lifestyle and anthropometric and physiological data.

Results highlighted a different glycemic response between men and women, suggesting the consumption of low-GI food rather than high-GI before physical exercise in order to keep plasma glucose levels constant.
Point-of-Care Diagnostics: Molecularly Imprinted Polymers and Nanomaterials for Enhanced Biosensor Selectivity and Transduction
Authors: Denmark Daniel J. , Mohapatra Subhra , Mohapatra Shyam S.
Published: October 2020

Significant healthcare disparities resulting from personal wealth, circumstances of birth, education level, and more are internationally prevalent. As such, advances in biomedical science overwhelmingly benefit a minority of the global population. Point-of-Care Testing (POCT) can contribute to societal equilibrium by making medical diagnostics affordable, convenient, and fast. Unfortunately, conventional POCT appears stagnant in terms of achieving significant advances. This is attributed to the high cost and instability associated with conventional biorecognition: primarily antibodies, but nucleic acids, cells, enzymes, and aptamers have also been used. Instead, state-of-the-art biosensor researchers are increasingly leveraging molecularly imprinted polymers (MIPs) for their high selectivity, excellent stability, and amenability to a variety of physical and chemical manipulations. Besides the elimination of conventional bioreceptors, the incorporation of nanomaterials has further improved the sensitivity of biosensors. Herein, modern nanobiosensors employing MIPs for selectivity and nanomaterials for improved transduction are systematically reviewed. First, a brief synopsis of fabrication and wide-spread challenges with selectivity demonstration are presented. Afterward, the discussion turns to an analysis of relevant case studies published in the last five years. The analysis is given through two lenses: MIP-based biosensors employing specific nanomaterials and those adopting particular transduction strategies. Finally, conclusions are presented along with a look to the future through recommendations for advancing the field. It is hoped that this work will accelerate successful efforts in the field, orient new researchers, and contribute to equitable health care for all.

Published: October 2020

Photodynamic therapy (PDT) is a photo chemotherapeutic strategy that is the application of photosensitizing agent and light on disease or tumor site. The aim of this study is to confirm the feasibility for femtosecond (fs) laser for aminolevulinate (ALA) mediated PDT on skin, breast and bladder cancer cells. Also the remarkable aspects of ALA mediated and laser induced PDT with respect to other literally known applications were investigated.

Metastatic melanoma cells SK-MEL30, mammary epithelial carcinoma cells MCF-7 and bladder cancer cells UMUC-3 were treated with ALA and then the cells were irradiated by fs laser at thirty wavelengths in between 230 and 800 nm for 30s and 60s. Anti-cancer effects of ALA phototherapy on different cancer cell lines were determined. Protoporphyrin IX (PpIX) accumulation was visualized by confocal microscopy. The effective PDT wavelengths were applied to evaluate the degree of apoptosis and necrosis in cells.

The viability tests demonstrated that wavelengths 400-440 nm and 600-630 nm were found to decrease the viability on three model cell lines. PDT at 630 nm exerted cell death by necrosis and apoptosis after 30 s and 60 s periods.

This paper confirms that ALA and femtosecond laser mediated PDT may be used together as therapeutic and diagnostic method to target breast, skin and urinary bladder cancer cells. The use of fs laser allows the flexibility for optimization of wavelength for photosensitizing agents.
Nile Red assay development for the estimation of neutral lipids in Chlorella emersonii and Pseudokirchneriella subcapitata
Authors: Priyanka Priyanka , Kinsella Gemma K. , Henehan Gary T. , Ryan Barry
Published: October 2020

Fluorescent dyes offer a useful method for the measurement of intracellular lipids. They are inexpensive and require simple optical measurement instrumentation, whilst simultaneously providing high throughput application. Nile Red is a hydrophobic, metachromatic dye which has been widely used for detection of intracellular lipids. However, Nile Red fluorescence depends on its concentration, microenvironment polarity, incubation time and, therefore, requires strain specific optimization. Hence, neutral lipids in Chlorella emersonii and Pseudokirchneriella subcapitata cannot be quantified using existing Nile Red methods developed for other microalgae strains and, therefore an optimised procedure for these strains is required. In this method development, the optimal excitation and emission wavelengths were selected based on the solvent used for Nile Red dissolution. The effect of Nile Red concentration, microalgae cell concentration, incubation time on fluorescence intensity was explored and optimised. Quintuplet assay repeats were executed for increased assay robustness for two microalgae strains, Chlorella emersonii and Pseudokirchneriella subcapitata, with protocol reliability confirmed by fluorescence microscopy. In brief, 20% (v/v) DMSO containing 10μg/ml and 5μg/ml Nile red was found to be ideal concentration for neutral lipid estimation in Chlorella emersonii and Pseudokirchneriella subcapitata respectively when an incubation time of 60mins and 40mins at 40°C was used. This optimised Nile Red protocol is a robust, simple and cost-effective method for neutral lipid quantification in Chlorella emersonii and Pseudokirchneriella subcapitata.
Optimization of Lyophilized LAMP and RT-PCR Reaction Mixes for Detection of Tuberculosis
Authors: Agel Esra , Sagcan Hasan
Published: October 2020

Undoubtedly, one of the most infectious diseases in the world is tuberculosis. Key factor for tuberculosis control is to prevent possible contagion with rapid diagnosis and effective treatment. The culture method, which it takes several weeks to obtain results, is the gold standard method for laboratory diagnosis of tuberculosis. In order to prevent possible contagion of tuberculosis, diagnosis must be made in short time and treatment should be started as soon as possible. Normally, clinical samples are studied in advanced laboratories designed for this purpose. However, especially after the screening in rural areas, the transmission of the samples to the centers has many negative effects on the clinical material. Therefore, the latest trend molecular techniques in microbiological diagnosis are developing into point of care systems that can be applied in the field without laboratory infrastructure. The major challenge for molecular-based point-of-care tests is the need to store polymerase enzymes and some of the ingredients used in the cold chain. The aim of this study is to increase the resistance of the amplification reaction mixtures by lyophilizing the tuberculosis diagnosis. Lyophilization was performed on Loop-mediated isothermal amplification (LAMP) and Real-time PCR mixtures. For the lyophilization of LAMP and RT-PCR mixtures, two different experimental setups were tried from the literature except for the developed content. Chemicals such as stachyose, trehalose, glycerol and PEG 8000 are widely using as cryoprotectants. As a result, the developed content (0.5% PEG 8000, 2.0 % Stachyose) was determined the best cryoprotectant mixture. Accordingly, amplification mixtures can be produced with the developed lyophilization method and point of care kits can be developed.
Relationship between organisational silence and employee demographic characteristics: the case of Lithuanian teachers
Authors: Jesevičiūtė-Ufartienė Laima , Brusokaitė Greta , Widelska Urszula
Published: October 2020

Organisational development requires creative and open employees, who must feel confident to use their inventiveness and share ideas. However, some entities encounter organisational silence. The lack of research into this phenomenon in Lithuanian educational institutions encouraged the authors of the article to investigate how demographic characteristics of teachers relate to types of organisational silence. The authors used two nonparametric tests for analyses, i.e. Mann–Whitney U to study gender and Kruskal–Wallis H to investigate age and marital status. The quantitative research targeted teachers of 104 Lithuanian secondary schools. The research findings contribute to filling the knowledge gap in the topic of organisational silence in Lithuania. The enclosed demographic characteristics can help rectify the current situation in educational institutions.
Controlling Effectiveness Model — empirical research results regarding the influence of controlling on organisational performance
Authors: Bieńkowska Agnieszka
Published: October 2020

The article aims to explain how controlling influences an organisation as a whole, considering the job performance of employees and managers. It describes the development and verification of the Controlling Effectiveness Model, which characterises the impact, the place of each variable and the direction of each relationship in the effort to shape organisational performance. The hypothesis was verified with the help of empirical research, which was conducted with 264 organisations operating in Poland. The survey took place in October 2019. The authors of the article used the CAWI method. Efforts had been made to ensure a diversified research sample encompassing various organisational characteristics. The exploratory and confirmatory factor analysis and the sequentially mediated regression model were used to verify the hypothesis. The empirical research allowed confirming a statistically significant indirect impact of the quality of controlling on organisational performance. This relationship depends on the job performance of managers and employees. The analysis of the impact made by controlling on the job performance of employees and managers as we as the organisational performance resulted in a mediation model (the Controlling Effectiveness Model) and confirmed the effect of controlling on organisational performance through the impact on job performance of managers and employees. The article has practical implications. The organisations that decide to implement controlling should focus on the quality of this management support method. It is not enough to simply implement controlling as organisations need to ensure the correct implementation. In this context, it is also relevant to properly shape functional, organisational and instrumental controlling solutions (tailored to the characteristics of the organisation as a whole, as well as to the environmental conditions, under which the organisation operates), which determine the quality of controlling.
Performance and causes of development problems among Latvian grain cooperatives
Authors: Mistris Jānis , Mistre Baiba , Zvaigzne Anda
Published: October 2020

The research aimed to examine Latvian grain cooperatives in terms of their performance and causes of development problems. The research employed several approaches, including a monographic method, induction and deduction, comparison, graphical method, statistical analysis, cause and consequence analysis and a sociological research method in the form of structured expert survey and interviews. The research examined the theory on cooperative development in Latvia and the world, analysed the Latvian grain production industry and made a statistical analysis of the performance of grain cooperatives. The total output of cereals was affected by the total area cropped with cereals, which was proved by the correlation coefficient r = 0.90. An increase in the area used for cereals leads to an increase in the total cereal output. The correlation coefficient showed a strong relationship between independent and dependent variables. Structured interviews with experts allowed the authors to identify the factors that hinder the development of grain cooperatives in Latvia. The industry experts identified the technological factor, i.e., poorly developed agricultural processing. As possible causes of the previously identified problem, experts identified a lack of financial resources, the unclear market situation, workforce problems, additional costs, and a lack of initiative in identifying new opportunities. The expert method helped to identify the most significant problem for the development of Latvian grain cooperatives and the underlying causes. The research allows drawing the attention of policymakers to the main problem regarding the development of grain cooperatives, namely, the technological factor of underdeveloped grain processing. The cooperatives did not own processing enterprises, which was mainly due to an unclear situation in the sales market.
Moderating role of corporate reputation in the influence of external support on organisational resilience and performance
Authors: Zabłocka-Kluczka Anna , Sałamacha Anna
Published: October 2020

The article analyses the influence made by corporate reputation on the mediation model for the impact of external support on organisational performance through resilience. The article aims to clarify the mechanism behind the moderating role of corporate reputation played in the influence of external support on organisational performance and considering the mediating role of organisational resilience. The empirical research was made to verify the existence of the relationship and to reach the aim of the paper. The set of hypotheses was built based on the theoretical research and then verified on the sample of 268 organisations operating in Poland. Dependences among the data selected from the theoretical research were analysed using statistical methods, including the correlation with the moderator and the mediated regression analysis. The obtained results clearly showed that corporate reputation was a moderator of the discussed mediation model for the influence of the external support on organisational performance through resilience. The paper contributes to further development of knowledge in organisational resilience management. It clarifies and stresses the role of two external factors: corporate reputation and external support in shaping the resilience of an organisation and its performance. The obtained results imply specific practical recommendations. Since corporate reputation can be the key to achieving greater organisational resilience and performance, special attention should be given to managing this category in an organisation.
Biomineralogical investigation of late-harvest grapes colonised by Botrytis cinerea Pers.
Authors: Grabowski Marek , Pawlikowski Maciej
Published: October 2020

The ripening process of two grape varieties in the vineyard located in the Sandomierz region was examined. In 2015, the ‘Regent’ and the ‘Sibera’ varieties reached physiological ripeness on 30th September and 3rd October, respectively. On both harvest dates, in addition to soluble solids content, titratable acidity, and pH, the macronutrient content was also determined. In the phase of physiological ripeness, the ‘Sibera’ variety showed higher acidity (1.02 g · 100 mL−1) compared with the ‘Regent’ (0.87 g · 100 mL−1). A higher soluble solids content was found in the ‘Regent’ (20.4°Brix), and slightly lower in the ‘Sibera’ (18.1°Brix). The must of the ‘Regent’ had a higher pH (3.5). This variety also had higher macronutrient contents (K, Ca and Mg). Grapes harvested after 3 weeks (late harvest) showed higher values of sugars, pH, K, and P for both varieties. However, their titratable acidity content, and Ca and Mg contents decreased. Microscopic examination showed differences in mycelial growth of Botrytis cinerea on grape bunches for both of the varieties left for the late harvest. The mycelial growth promoted faster dehydration of the ‘Sibera’ berries. Spot chemical analyses of ‘Sibera’ berry peel performed using EDS (energy dispersive spectroscopy) showed the occurrence of elevated contents of potassium, phosphorus, sulphur, magnesium and silicon. Around skin cracks, sugar crystals as well as hard-to-identify microcrystals were formed containing potassium. On the surface of the ‘Regent’ berries, potassium, and traces of phosphorus, silicon, magnesium, sulphur and calcium were found.
Effect of no-tillage and tillage systems on melon (Cucumis melo L.) yield, nutrient uptake and microbial community structures in greenhouse soils
Authors: Zhang Jian , Wang Jiajia , Wang Pengcheng , Guo Tingting
Published: October 2020

No-tillage (UT) and tillage (TL) influence melon (Cucumis melo L.) production. However, the mechanism of improving the soil quality under UT in melon production is still unavailable. In this study, we attempted to explore the effects of UT and TL treatments on soil fertility and the microbial abundance and diversity in planting melon under greenhouse condition. Soil properties were determined and the bacterial v4-v5 16S rRNA and the fungal internal transcribed spacer gene were pyrosequenced by extracting greenhouse soil DNA. Results showed that the two treatments had different effects on nutrient uptake in melon plants under facility conditions. Additional nitrogen (N) was absorbed in the leaves and fruit in UT treatment. However, the N content in the UT treatment was kept as similar to that of the TL treatment. The phosphorus (P) contents in melon plant leaves and fruits in the UT treatment were higher than those in the TL treatment. High potassium (K) contents were observed in fruits and melon stem under the UT and TL treatments, respectively. Soil pH, organic matter and the available N influenced the bacterial and fungal distributions. The total N, total P and total K in melon plants were correlated with the bacterial and fungal groups in facility soils. The UT treatment had a substantial effect on the microbial diversity in soils planted with melon. Our study provided insights into the response of soil fertility and microbial structures to UT and TL treatments under greenhouse soils, which may aid in managing greenhouse soil quality.
National Lists of Scholarly Publication Channels: An Overview and Recommendations for Their Construction and Maintenance
Authors: Pölönen Janne , Guns Raf , Kulczycki Emanuel , Sivertsen Gunnar , Engels Tim C. E.
Published: October 2020

Purpose

This paper presents an overview of different kinds of lists of scholarly publication channels and of experiences related to the construction and maintenance of national lists supporting performance-based research funding systems. It also contributes with a set of recommendations for the construction and maintenance of national lists of journals and book publishers.

Design/methodology/approach

The study is based on analysis of previously published studies, policy papers, and reported experiences related to the construction and use of lists of scholarly publication channels.

Findings

Several countries have systems for research funding and/or evaluation, that involve the use of national lists of scholarly publication channels (mainly journals and publishers). Typically, such lists are selective (do not include all scholarly or non-scholarly channels) and differentiated (distinguish between channels of different levels and quality). At the same time, most lists are embedded in a system that encompasses multiple or all disciplines. This raises the question how such lists can be organized and maintained to ensure that all relevant disciplines and all types of research are adequately represented.

Research limitation

The conclusions and recommendations of the study are based on the authors’ interpretation of a complex and sometimes controversial process with many different stakeholders involved.

Practical implications

The recommendations and the related background information provided in this paper enable mutual learning that may feed into improvements in the construction and maintenance of national and other lists of scholarly publication channels in any geographical context. This may foster a development of responsible evaluation practices.

Originality/value

This paper presents the first general overview and typology of different kinds of publication channel lists, provides insights on expert-based versus metrics-based evaluation, and formulates a set of recommendations for the responsible construction and maintenance of publication channel lists.

Authors: Jakubowski Krzysztof , Paś Jacek
Published: October 2020

The article presents a general method for identity the security risk factor for alarm signal transmission systems (ASTS), which are used in monitoring buildings and critical infrastructure. The security of the transmission of alarm signals to an alarm receiving center (ARC) is a property of the process, which is associated witch performing of tasks and functions, human factor, hardware and environment components. The process of transmitting alarm signals should be characterized by minimizing risk of external and internal interception/distortion or deformation of transmitted signals and in ideal case signals should be encrypted and integrity checked. Determining the security risk indicator for ASTS will allow optimal organization of electronic security systems.

For this purpose, a flight simulator of the Cessna 172 RG aircraft from the ELITE Company was used. For the purpose of verifying the take-off run length, the article provides a measurement methodology that was developed using information obtained during experimental take-offs. The aim was to obtain a procedure that would allow for repeated take-off runs in the same conditions with the possibility of changing individual influencing factors. Considering the whole measurement chain, the article analyses the influencing factors and quantifies their impact on the uncertainty of the measurement result. The data obtained experimentally we compared with the data in the Flight Manual and at the end carried out the assessment of the impact of global warming on the take-off run of the Cessna 172 RG and generally on the safety of the take-off and on air transport..

The most desirable effect of motorization development is providing a drive unit with high performance parameters and reduce the environmental impact. This study presents the results of tests of a self-ignition engine power output and torque. The tested engine was powered with diesel oil and a mixture of fatty acid methyl esters in the proportions of 10%, 30% and 50% with performance additives, for standard settings of the fuel injection system. The tests were carried out on a chassis dynamometer for full load of the engine. The vehicle was placed on the dynamometer rollers and attached to the base by means of belts. The analysis shows that application of the mixture decreases the engine performance parameters to such a degree that the engine is not put at any risk of damage.

Published: October 2020

The introductory part of the article discusses briefly the basic principles and methods of towing large aircrafts. Then, events that occurred while different large passenger planes were towed are analyzed. Based on the analysis, the main causes of plane damages during towing are indicated. The percentage distribution of individual identified risk factors is determined to show that the main cause is the broadly understood human factor, especially errors of service personnel and the crew. Finally, preventive recommendations were made based on the analysis; they can help avoid such events. The analysis stimulates further research in this field and highlights the necessity to continuously analyze the risk, which should minimize the number of towing-related incidents.

At present, one of the most frequently discussed topics, not only at international conferences, but also within the EU, is the issue of airport financing, as well as the thresholds at which airports can cover their operational costs and when the need for support is justified. The Strategic Airport Development Plan and the Airport Business Plan are one of the most important support documents for making the right decision for airport financing and prepare the project for operational and investment aid. For preparing these documents is significant the category of the airport, that means the number of passengers. This paper is focused on the methodology how can be predict the number of passengers from previous data by used the time series method.

The article addresses investigating the possibilities of making a parameterized flight dynamics model in a mixed reality environment. The purpose was to obtain a model for a Mi-17 helicopter. The Mi-17 VI helicopter flight test characteristics were used to evaluate the above model. As a comparative criterion, compatibility between the model’s selected characteristics and the real object was adopted. Simulation tests were conducted on a cabin simulator set made via MR (mixed reality) technology. Test results confirmed the possibility of reconstructing the selected helicopter type’s flight dynamics using the parameterized model.

Published: October 2020

Hydraulic pumps are among the most complex and responsible units from the point of view of aircraft flight safety. One of the most important scientific and technical problems in improving the reliability of hydraulic pumps is to understand the physical nature of the cause of damage in them and on this basis to develop measures and recommendations to ensure their reliability. The article discusses the characteristics of hydraulic piston pairs of hydraulic pumps according to the kinematics of their movement and load conditions. Selected actual damages of axial piston pumps are discussed. The paper presents a simplified 3D solid model of the cylinder-piston assembly and the mechanism for adjusting the inclination of the piston cylinder block, the axial hydraulic pump, and the model of breaking loads for selected elements of this pump. The digital solid model and element load analysis were developed in SolidWorks Simulation.

The Advantages of Using a Bleed of Air from Behind the Compressor and Supplying It Behind the Turbine in an Aircraft Engine
Authors: Kowalski Mirosław , Kotlarz Wojciech
Published: October 2020

The research paper discusses the advantages of using compressor downstream air partial bleed and supplying it downstream of the turbine, which was applied in a prototype of a “bypass” turbojet engine. The impact of such a solution on the value of achieved basic operating parameters of the engine was described, i.e., unit thrust and unit power consumption. The presented attempt to compare these parameters with the parameters achieved for a turbojet, single flow engine is very important; in the first case without air bleed, and in the second, with air bleed to the environment and with the parameters of a turbojet, turbofan engine with a jet mixer.
