MWD and MPD System Combination Successfully Manages Ultra-High LCM Concentrations and Cement Slurries in Loss Scenarios
Authors: Valerio Alexander , Carvalho Gabriela Luisa
Published: February 2020

Whilst drilling the 12 ½" and 8 ½" sections on a HPHT field in the North Sea, fluid losses were encountered which required the pumping of high concentration Loss Circulation Material (LCM) as well as multiple ‘through the bit’ cement squeezes. The reservoir had been under production for many years and was now at a point where it had significantly depleted and the formation was very delicate, making it easily subjected to fracturing. Losses were expected to be an upcoming challenge as the mud weight window was so narrow and due to the HPHT rating of the offshore reservoir and the fractured nature of the geology, this posed as a serious risk that required pre-planned mitigation.

The ability to pump ultra-high LCM concentrations was discussed in pre-planning as being one of the key mitigation strategies to stemming losses. However, it was thought that pumping LCM would block a typical MWD pulser due to the narrow geometries of the flow paths within. Successful onshore testing was conducted prior to drilling operations to prove that the MWD pulser selected had the ability to permit the flow of ultra-high concentrations of LCM. A closed loop system was created onshore and LCM with concentrations up to 420kg/m3 (147lbs/bbl) was pumped through the MWD tool without blocking it up and with full functionality throughout. This gave the operator the confidence to pump LCM through the MWD tools, if required in the field.

The use of an MPD (Managed Pressure Drilling) system was also required to keep the equivalent circulating density within the tight mud weight window by maintaining a constant bottom-hole pressure through the application of Surface Back-Pressure (SBP). This was critical as the well, when static, was underbalanced. The incorporation of MPD also gave the operator the ability to ‘squeeze’ LCM/cement into the well and formation by applying surface back pressure during ‘through the bit’ LCM/cement jobs. During field operations, the operator did go on to pump a 320 kg/m3 (112 lbs/bbl) LCM pill through the MWD tool without plugging during a loss scenario. Pumping LCM through the MWD tool reinforced the formation and enlarged the mud weight window from <0.01sg to 0.03sg allowing operations to continue. In addition, muliple "through the bit" MPD LCM/cement squeezes were conducted on two wells in the same field with no negative effect on any of the MWD tools.

The partnership between the MWD and MPD systems formed a key part of the losses management. The MWD system could identify exactly what downhole pressure losses were seen at, which was then transmitted by the pulser to the surface. The MPD system would then use an algorithm based calculation to apply the exact required SBP to maintain a constant bottomhole pressure, that was within the mud window. This provided the operator a safe and efficient solution to continue to the target depth in a very challenging narrow margin well.

Wellbore instability is caused by the radical change in the mechanical strength as well as chemical and physical alterations when exposed to drilling fluids. Unscheduled events that are related to wellbore instability account for more than 10% of the drilling cost, which is estimated to one billion dollars per annual cost. Understanding shale-drilling fluid interaction plays a key role in minimizing drilling problems in unconventional resources. The need for providing a more suitable drilling fluid system for drilling operations in unconventional resources is growing. The major consequences of improper fluid selection include bit-balling, hole sloughing, and most importantly low drilling rates. This study will evaluate the effect of different inhibitive drilling fluid systems on shale drilling performance. The mud systems use in this study include cesium formate, KCl based mud systems, and a conventional water-based mud. The conventional water-based mud is used as reference fluid. An innovative HPHT drilling simulator is used to perform real-time drilling operations on cylindrical shale core samples obtained from the Tuscaloosa Marine Shale (TMS). The process involved simulating real-time drilling operation at downhole conditions where different fluids served as drilling fluid. A comparative analysis of the impact of each drilling fluid systems on the drilling performance as then performed. The analysis focused on drilling parameters such as rate of penetration, torque, and friction factor during drilling. This paper evaluates the compatibility between different fluid systems and shale formations. The paper also provides an overview of the effect of the inhibitive mud systems on drilling performance. The inhibitive muds systems (KCl based fluids and cesium formate) provided improved drilling performance compared to conventional water-based mud.

Enhancement of Water Imbibition in Shales by use of Ketone Solvent
Authors: Argüelles-Vivas Francisco J. , Wang Mingyuan , Abeykoon Gayan A. , Okuno Ryosuke
Published: February 2020

This paper presents an application of 3-pentanone, a symmetric short ketone, to enhance the water imbibition in coreflooding of fractured carbonate cores. 3-Pentanone was tested in two ways: 1.1-wt% 3-pentanone solution in reservoir brine (3pRB) and pure 3-pentanone (3p) as a miscible solvent. It was presented previously that 3p is a mutual solvent for oil and water, and can rapidly change the rock wettability to strongly water-wet with its electron-rich oxygen atom through the oil and water phases. The main objective of this research is to investigate how the initial water saturation in the matrix affects the imbibition of 3pRB or 3p from the fracture and the resulting recovery of oil from the matrix.

The experimental results were analyzed in terms of material balance (mass and volume) with simplifying assumptions. This analysis enabled to estimate how much of the injected components were imbibed into the surrounding matrices from the fracture and the relative contribution of the injected components to displacing oil in the matrix.

For the injection of 3pRB, the oil recovery was consistently greater when there was an initial aqueous phase in the matrix. While the presence of an initial aqueous phase did not affect the imbibed fraction of the injected 3p, it made it more effective for 3p to enhance the oil displacement by water in the matrix. For example, 87% of the oil recovered from the matrix was displaced by water (the rest by 3p) for the coreflood with an initial water saturation of 31%.

The injection of pure 3p showed that a larger amount of oil was recovered from the matrix with the presence of an initial aqueous phase in the matrix. The oil recovery mainly came from the displacement of oil by 3p in the matrix with a minor contribution of water. Results for the 3pRB and 3p injections indicate collectively that 3-pentanone was more effective in enhancing oil recovery when an aqueous phase was initially present in the matrix.
Quantitative Analysis of the Effect of Perforation Interaction on Perforation Stability Using the Finite Element Method
Authors: Araki Naoto , Morita Nobuo
Published: February 2020

Although a well has hundreds of perforations, a single perforation is normally used for perforation interaction analysis assuming the perforations are shot symmetrically and the stress state around a perforation is symmetric in both vertical and horizontal directions. However, for the single/double spiral perforations shot in inclined wells, no vertical and horizontal symmetry surfaces exist. Required elements for multi-perforation model are more than 10,000, which results in complex mesh generation and long computation time. This study investigates perforation interaction to find the optimum perforation design which yields the highest productivity while maintaining mechanical stability.
Introduction of Newly Deployed Wellbore Cleaning Technique

Published: February 2020

It is common knowledge that over its life-cycle an oil producer or water injector may experience a reduction in near-wellbore permeability or overall fluid connectivity to or from the reservoir from in-wellbore impediments that negatively impact productivity or injection. Such permeability reductions or fluid connectivity losses are often related to near-wellbore damage or ‘skin’ or in-well damage induced by fill, scales, waxes, asphaltene or other blocking mechanisms. In recent years an increasing number of coiled tubing ("CT") stimulation and cleanout interventions has led to the advancement of downhole tools focused on remediating such damage mechanisms. One such development that has been successfully deployed to re-establish water injection rates for reservoir pressure support in oil field production operations is a multi-directional, cavitational-based fluid pulsing tool that provides a hydro-mechanical means to both remove detritus materials from the immediate wellbore but also stimulate the near-wellbore region.

Sieve analysis, sedimentation and laser diffraction have been the methods of choice in determining particle size distribution (PSD) for sand control design. However, these methods do not provide any information regarding the particle shape. In this study, we introduce the application of Dynamic Image Analysis (DIA) to characterize particle sizes and shape descriptors of sand bearing formations.

Dynamic Image Analysis, an advanced method of particle size and shape characterization, along with other PSD measurement methods, including sieving combined with sedimentation, and laser diffraction, was utilized to study size and shape variations of 372 unconsolidated formation sand samples from North America, Latin America, and the Middle East. Different methods were compared for the estimation of PSD and fines content, which is important for sand control design.

Through minimizing the sampling and measurement errors, the deviation between different PSD measurement techniques was attributed solely to the shape of the particles and the amount of fine fraction. For fines content measurement, the values obtained through Feret Min. parameter values (the minimum size of a particle along all directions) calculated by DIA and sieving measurement are comparable within a 5% confidence band. The deviation between the results of different methods becomes more significant by increasing fines content. Moreover, this deviation increases for less isodiametric grains. The fines and clay content show higher values when measured by any wet analysis. Laser diffraction also tends to overestimate the fines fraction and underestimate silt/sand fraction compared to other dry techniques. By comparing the deviation of the DIA and sieving at standard mesh sizes, an algorithm has been developed which chooses the equivalent sphere sizes of DIA with minimum deviation from sieving.

This study performs several measurements on formation sands to illustrate the real advantage of the new methods over traditional measurement techniques. Furthermore, particle shape descriptors were used to explain the deviation between the results of different PSD measurement methods.

Published: February 2020

Background: The aim of this review was to evaluate the efficacy and tolerability of ubrogepant in patients with episodic migraine. Methods: We systematically searched PubMed, Embase, MEDLINE, Cochrane Library, and clinicaltrials.gov from inception to JULY, 2019. Randomized controlled trials of the efficacy and/or tolerability of ubrogepant for migraine were included. Meta-analysis was conducted by RevMan 5.3 software. Results: A total of 4 RCTs involving 4 163 patients were included. The meta-analysis showed that there were significant differences in the percentage of subjects with PF, PR, SPF, SPR, sound without phobia, light without phobia and nausea compared with the control group. (RR=1.31,95%CI:1.18~1.45，P<0.00001, RR=1.63,95%CI:1.46~1.82，P<0.00001, RR=1.22,95%CI:1.15~1.29，P<0.00001, RR=1.32,95%CI:1.22~1.42，P<0.00001, RR=1.16,95%CI:1.05~1.27，P=0.002), all the differences were statistically significant. Conclusions: For adult patients with episodic migraine, ubrogepant could effectively abort the acute attack. High-quality, adequately powered RCTs are needed to fully evaluate the efficacy and tolerability of ubrogepant for episodic migraine.

Published: February 2020

Background: Canine vector-borne pathogens (CVBP) comprises a relevant and globally distributed group of disease agents. The aim of this study is to determine de co-occurrence of the most relevant CVBP of veterinary and zoonotic interest, in free-ranging, owned, rural dogs of central Chile, and to evaluate risk factors and potential “hidden” hematological alterations associated to pathogen co-infection by two or more pathogens.Methods: Nine groups of canine vector-borne pathogens (CVBP) were molecularly investigated in 111 free-ranging, owned rural dogs in the Metropolitan Region of Chile. Results: At least one pathogen was detected in 75% of the dogs. The most prevalent agent was Anaplasma platys (36%), followed by Candidatus Mycoplasma haematoparvum (CMhp; 31%), Mycoplasma haemocanis (Mhc; 28%), Trypanosoma cruzi (17%), Leishmania spp. (4.5%) and Acanthocheilonema reconditum (1%). DNA of Ehrlichia spp., Rickettsia spp., Bartonella spp., Piroplasmida and Hepatozoon spp. was not detected. Thirty-eight dogs (34%) were coinfected, either by two (n=20), three (n=7), or four agents (n=1). The most common co-infection pattern was CMhp – Mhc (n=14). CMhp was involved in 71%, Mhc in 58%, and A. platys in 50% of the co-infections. Prevalence of A. platys was higher in juvenile than in adult dogs, whereas the opposite was found for CMhp and Mhc. Adult dogs had five times more probabilities of being coinfected than young animals. Dogs positive for A. platys were infested by a larger number of Rhipicephalus sanguineus sensu lato ticks than uninfected individuals. At clinical evaluation, most of the animals were considered healthy, with only eight dogs (7%) presenting pale mucous membranes. Co-infected animals showed higher white blood cell count, segmented neutrophil count and GGT levels than non-co-infected dogs. Conclusions: This study represents the first report of Leishmania sp. in Chile. Clinically healthy but infected dogs as those studied here may act as reservoirs of CVBP, potentially contributing to the spread of these pathogens to other tick-exposed dogs as well as human beings or protected wild carnivores.

Authors: Guettaf Youcef , Kenai Said , Khatib Jamal , Yahiaoui Walid
Published: February 2020

Aims:

The aim of this study is to discuss the performance of SCC with natural
pozzolana under hot climate conditions.

Background:

The performance of vibrated concrete under hot climate is well investigated.
However, the effect of hot climate on SCC is tittle investigated. North African and Middle
Eastern countries are subjected to hot and dry environments especially during summer periods.
Hence there is a need to investigate the performance of SCC under hot climate.

Objective:

The objective of this paper is to study the effect of water curing duration followed
by natural hot climate exposure on the performance of SCC with Natural Pozzolan
(NP).

Methods:

It is an experimental investigation where Concrete specimens were exposed to a
standard curing environment (relative humidity RH = 100% and Temperature T°= 20°C ± 2°C)
for 0, 1, 3, 7, 14 and 28 days, followed by a second cure in a hot environment in open air on
a laboratory terrace in North Africa area during summer time with a temperature of 35°C to
45°C and a relative humidity of 65% to 75%. The cement was substituted by NP in weigh at
three substitution levels (0%, 15% and 25%).

Results:

The experimental results show the importance of the wet curing in hot climate, especially
when NP is used. Substituting cement by NP improves the self-compacting concrete
durability for the long term.

Conclusion:

The substitution of cement by natural pozzolan reduced water permeability and
capillary absorption. The hot climate has no negative effect on the evolution of the mechanical
strength and durability of the SCC with natural pozzolan when undergoing a long initial
wet cure.

Para el mundo de las ciencias sociales es sabido el problemático contenido del concepto región, sobre todo al constatar que en muchas ocasiones este constructo está prefigurado con base en dinámicas económicas, políticas, sociales, culturales y territoriales que se transforman a lo largo del tiempo. Ello hace que, en sentido estrictamente espacial, las regiones sean entes cambiantes, por ende la imposibilidad de su delimitación por parte de políticas públicas que las intenten configurar en escenarios de la administración gubernamental. Con base en esta constatación, el presente dossier da cuenta de diferentes escenarios territoriales que se articularon alrededor de actividades económicas específicas, las cuales lograron prefigurar escenarios en los cuales diversos agentes desarrollaban formas de interrelación que constituyeron a las regiones como escenarios intermediarios entre el espacio local y global. En algunos casos, los autores logran demostrar cómo tales fenómenos trascendieron el ámbito eminentemente material y llegaron a ser pieza constitutiva del andamiaje simbólico, político y social sobre el cual se desarrollaron diversos conglomerados, algunos de los cuales trascendían el escenario nacional, demostrando el carácter variable de los procesos de regionalización.
A escrita intermediária web documentária: um dispositivo metodológico para a produção do saber

Published: February 2020

Ao longo deste artigo, trataremos sobre a utilização científica de uma ferramenta hipermidiática web documentária como dispositivo metodológico de análise dos discursos. Descreveremos o desenvolvimento da nossa metodologia e a construção de tal dispositivo, interpretado como a “escrita intermediária” (Achard, 1994) de uma pesquisa doutoral em Ciências da Informação e da Comunicação. A tese em questão debate a produção patrimonial através dos discursos sociais, uma pesquisa que produziu e coletou uma heterogeneidade de documentos (audiovisual, fotográfico, sonoro, cartográfico, jpeg, pdf, etc). O dispositivo metodológico web documentário autoriza a manipulação destes documentos heterogêneos, permitindo ao pesquisador de analisar semio-pragmaticamente os discursos. O trabalho de organização e de estruturação do conjunto documentário evidencia por fim a construção da “representação documentária” (Tardy, 2012) da pesquisa.

Published: February 2020

Представлен обзор работ по решению обратных задач рассеяния звуковых волн упругими телами. Теоретические основы решения обратных задач дифракции звука базируются на фундаментальных исследованиях проблемы обратных задач для уравнений в частных производных, выполненных отечественными учеными. В самой общей классификации обратные задачи акустики делятся на обратные задачи излучения (ОЗИ) и обратные задачи рассеяния (ОЗР). При решении задач первого класса по характеристикам звукового поля определяют некоторые параметры излучателя. При решении задач второго класса измерения параметров рассеянного звукового поля используют для идентификации свойств рассеивающего объекта. Большая часть приложений акустических методов основана на решении обратных задач дифракции, когда по параметрам излучаемого или отраженного звукового поля судят о параметрах объекта или среды. Анализ звуковых полей составляет основу методов в гидро- и аэроакустике; исследований в биологии и медицине; неразрушающего контроля и диагностики объектов; ультразвуковой дефектоскопии; обследовании и испытании материалов, конструкций и сооружений. Решения всех обратных задач основаны на решении прямых задач дифракции. В работе представлены наиболее значимые результаты в решении прямых задач рассеяния звуковых волн упругими объектами. Выделены работы, посвященные проблемам обратных задач рассеяния звука неоднородными упругими телами. Это направление составляет предмет интересов в исследованиях авторов.

Methods for identifying counterfeit money in the territory of the Principality/Kingdom of Serbia in the 19th century
Authors: Jaukovic Gordana , Knezevic-Lukic Nevenka
Published: February 2020

Counterfeiting is one of the oldest and most persistent criminal offences.
Scientific and technological development has enabled the emergence of a more
modern money manufacturing technology and improvement of money protection
systems, though at the same time it broadened the possibilities for criminal
offences, notably the production of counterfeits. In the mid-1860s, the
money in circulation in the Principality/Kingdom of Serbia was of foreign
origin, comprising 43 types of different metal coins and one type of paper
money. Gold and silver money of European origin was deemed by the people to
be better and ?purer? than Turkish money. In an effort to establish control
over the technological process of manufacturing the national currency and at
the same time prevent the counterfeiting of money of different types and
origin, the Principality of Serbia appointed chemists Mihajlo Raskovic and
later Sima Lozanic, as ?examiners of ores and false money?. Almost all
counterfeit currencies appeared immediately in circulation in the territory
of the Principality/Kingdom of Serbia. This paper presents the methods used
in the process of identifying false/suspect money, methods used to determine
the nominal value of money, the importance of introduction of those
scientific methods in the criminal and legal sphere of the
Principality/Kingdom of Serbia, which can be considered the beginning of the
forensic chemistry in Serbia.
Der ungeklärte ethnische konflikt und die soziale kluft zwischen den Juden und den Samaritanern in Joh 4: 4-42
Authors: Kostresevic Milan
Published: February 2020

In wissenschaftlichen Interpretationen der Begegnung Jesu mit der Samariterin
wird oft vorgeschlagen, dass sie als ein erster Schritt in Richtung
Vers?hnung zwischen den Juden und den Samaritern erl?utert wird. Diese
Analyse ergibt sich aus den erz?hlerischen Details des johanneischen Textes,
in dem die Samariterin den j?dischen Jesus als Propheten (4,19) und einen
m?glichen Messias (4,29) anerkannte. Sp?ter luden die samaritanischen
Dorfbewohner ihn zu ihrem Platz ein, dem er ohne weiteres zustimmte (4,40).
Nach seinem Besuch haben sie ?berzeugt gestanden, dass er tats?chlich der
?Erl?ser der Welt? ist (4,42). Mit dieser Abfolge von Ereignissen scheint
sich der ethnische Bruch zwischen den beiden ethnischen Gruppen zu l?sen.
Diese Annahme l?sst jedoch die Dynamik zwischen den verschiedenen ethnischen
Gruppen au?er Acht, insbesondere das Vorhandensein einer ethnozentrischen
Haltung unter den Gruppenmitgliedern. Diese Studie nimmt seine Existenz
unter allen Charakteren von Joh 4: 4-42 wahr, einschlie?lich des
johanneischen Jesus. Um diese Behauptung zu untermauern, zielt diese Arbeit
darauf ab, die gesamte Erz?hlung kritisch zu betrachten, wobei insbesondere
den Versen, in denen das Thema ethnische Identit?t entweder best?tigt oder
in Frage gestellt wird, besondere Aufmerksamkeit gewidmet wird, um zu pr?fen
und zu untersuchen, ob tats?chlich erste Schritte zur Harmonisierung
ethnischer Herkunft unternommen werden oder nicht. Da kein Schritt in dem
Sinne auch nach dem Lesen dieses Ph?nomens in Bezug auf moderne
Indentit?tskonzepte gefunden wurde, schl?gt man vor, die Perikope als reine
Glaubensbekehrung der Samaritaner zu Jesus zu lesen, der zuf?llig ein Jude
ist.
Using the intervention ladder to examine policy influencer and general public support for potential tobacco control policies in Alberta and Quebec

Published: February 2020

Objective

To assess general public and policy influencer support for population-level tobacco control policies in two Canadian provinces.

Methods

We implemented the Chronic Disease Prevention Survey in 2016 to a census sample of policy influencers (n = 302) and a random sample of members of the public (n = 2400) in Alberta and Quebec, Canada. Survey respondents ranked their support for tobacco control policy options using a Likert-style scale, with aggregate responses presented as net favourable percentages. Levels of support were further analyzed by coding each policy option using the Nuffield Council on Bioethics intervention ladder framework, to assess its level of intrusiveness on personal autonomy.

Results

Policy influencers and the public considered the vast majority of tobacco control policy options as “extremely” or “very” favourable, although policy influencers in Alberta and Quebec differed on over half the policies, with stronger support in Quebec. Policy influencers and the public strongly supported more intrusive tobacco control policy options, despite anticipated effects on personal autonomy (i.e. for policies targeting children/youth and emerging tobacco products like electronic cigarettes). They indicated less support for fiscally based tobacco control policies (i.e. taxation), despite these policies being highly effective.

Conclusion

Overall, policy influencers and the general public strongly supported more restrictive tobacco control policies. This study further highlights policies where support among both population groups was unanimous (potential “quick wins” for health advocates). It also highlights areas where additional advocacy work is required to communicate the population-health benefit of tobacco control policies.

This paper aims at analysing the rise of innovative and experimental poetics within the American poetic grounds and the factors that remain extremely influential in establishing an alternate poetic culture that emerged with the rise of modernism within poetic circles. With influential and significant American poetic voices like Ezra Pound, T.S. Eliot and innovative women poets like Gertrude Stein popularising the use of ‘experimental’ techniques within the processes of poetic construction, the American poetic culture witnessed the rapid growth of an alternate realm of poetic activity that particularly gained significant recognition in the post-war era. This paper attempts to present an overview of the various post-war poetic groupings that contributed to the establishment of an experimental tradition within contemporary American poetics.
Mechanisms of Interaction Between the State and Capitalism: History and Modernity (Article 2)
Authors: Tambiyants Yulian Grigoryevich , Shalin Viktor Viktorovich
Published: February 2020

The study analyzes the mechanisms of interaction between government institutions and big businesses in the period of organized capitalism as well as modern globalization. In the authors’ opinion, even a kind of bourgeois-based state was largely autonomous and performed functions assigned to it by society at the stages of primitive accumulation and organized capitalism. It took place during the large-scale economic crisis that shook the foundations of the capitalist system. In that period, the authorities revised their involvement in economic processes by taking ultimate responsibility for redistribution and by overcoming obvious resistance to business community. At the present stage of global capitalism, the official elites and big businesses still tend to converge or even intermingle and merge. A common environment of politicians and top managers is established on the basis of class and ideological unity. The alliance between big businesses and government institutions is becoming increasingly organic and inseparable, which affects political decisions accordingly. It is of the utmost importance that these processes result in a growing class nature of the modern state. An emerging political and economic hybrid can only be effective in neo-liberalist context.
Tabaco e Equipamento de Proteção Individual na Colheita. A Compreensão dos Agricultores Familiares no Sul do Brasil

O presente artigo objetiva analisar a compreensão dos agricultores que produzem tabaco no sul do Brasil acerca da utilização do equipamento de proteção individual (EPI) na colheita do tabaco. Associado ao manuseio do fumo verde há um risco da intoxicação por nicotina, conhecida como doença da folha verde do tabaco – DFVT, a qual poderia ser evitada com a utilização de EPI. Pouco se conhece das práticas, das adaptações e do entendimento que os agricultores fazem do EPI de colheita. Via a utilização da perspectiva orientada aos atores (POA) e com o suporte de múltiplos estudos de casos verificou-se a hipótese de que os agricultores embora reconheçam a necessidade do uso do EPI, usam práticas/estratégias  diferenciais baseadas em suas vivências para lidar com a possibilidade de intoxicação pela nicotina. Os resultados confirmam que os produtores conhecem o EPI, a DFVT e as relações entre as duas. Contudo, possuem esparsas informações sobre a limpeza do EPI e pouco se protegem no manuseio das folhas nas estufas, especialmente pela ocorrência de uma nova forma de intoxicação, nominada por eles como “bafo do fumo quente”. Finalmente, o artigo reflete as adaptações e inovações fundamentadas nas experiências dos agricultores (capacidade de agência) que ao mesmo tempo não seguem as recomendações oficiais, trazem indagações sobre o desenvolvimento de novos produtos e processos para qualificar a vida destes agricultores.
Flowering and fruiting of Ananas comosus L. Merr. in two cultivation systems under subtropical conditions

Published: February 2020

Pineapple production in the subtropics is limited by low temperatures. Frost affects the growth and development of the plants, being the main factor that compromises production. One way to mitigate this problem is the use of plastic covers (greenhouses), which could, however, negatively affect the productivity. We studied the flowering and fruiting of pineapple (Ananas comosus L. Merr.) in two cropping systems (greenhouse and field) in a subtropical region in the northeast of Argentina. Two experimental batches, with plastic covers and uncovered, divided into eight plots, were set up and phenological crop monitoring was performed. The experimental design was completely random. At the time of harvest, physical and chemical variables, such as length of fruit length with crown, fruit length without crown, equatorial diameter, density, firmness, °Brix and acidity values, were analysed to represent fruit quality. The results showed significant differences between the cultivation systems studied. Cultivation type had a marked effect on fruit quality; fruits produced in the greenhouse had a higher weight and size than those produced in the field; however, the chemical variables related to flavour did not differ significantly between the two cultivation types.

Salah satu identitas etnik Jawa yang hadir di Makassar adalah dengan panggilan Mas bagi orang Jawa laki-laki. Panggilan Mas ini telah berlangsung sekian lama dan belum diketahui pasti kapan dimulainya, dengan rentang waktu, maka identitas Mas sudah menjadi milik orang Jawa laki-laki di Sulawesi khususnya Makassar. Kedua etnik di Makassar yakni; etnik luar Jawa dan etnik Jawa memiliki pemakaan yang sama terhadap Mas yaitu; merupakan sapaan untuk memberikan penghormatan kepada orang lain dan sebagai pintu keakraban terhadap orang yang belum diketahui identitasnya, terutama untuk para pedagang, sapaan Mas merupakan hal yang biasa, namun yang menjadi problem adalah pada aplikasi dan generalisasi terhadap etnik Jawa di Makassar.
Long-term monitoring of a winter bat assemblage revealed large fluctuations and trends in species abundance

Published: February 2020

Monitoring studies in Strzaliny, one of the greatest hibernacula in Poland, comprised 31 annual bat censuses (1989–2019). The abundance peaked in 2002 for Myotis myotis, 2009 for Myotis nattereri and 2008 for the whole assemblage. Comparison of the maximum abundance in the monitoring period with that from 1980 to 1982 showed an almost fourfold increase for the whole assemblage, tenfold increase for M. nattereri and fourfold increase for M. myotis.

In 1989–2019, the numbers of M. myotis, M. nattereri, Myotis daubentonii and Plecotus auritus were fluctuating, but most of the recorded changes could not be explained by methodological problems or a direct human impact. Therefore, the cumulative results largely reflected the real trends in the species abundance. A long-term upward trend in the whole bat assemblage was recognisable, but with a stable or slightly decreasing phase in the last decade. An upward trend in M. nattereri was even stronger and has only slightly flattened recently. In M. myotis, the trend was clearly upwards up to the early 2000s, but weakly downwards in the following years. In M. daubentonii and P. auritus, no significant trend was determined. In strongly fluctuating M. daubentonii, the numbers were mostly moderate or high, and even increasing, up to 2008 and only moderate or low in the following years. In P. auritus, an increase occurred in the 1980s and early 1990s, and then, after the stochastic human-induced drop in 1994, its abundance remained relatively stable.

The population trends in Strzaliny largely reflected the general trends assessed for a large part of Europe. This suggests that the general population trends may be recognisable even in one large winter assemblage if it is reliably and consistently monitored through a long period. In this context, the hibernaculum in Strzaliny appeared to be a model object for such studies.

КОМПАРАТИВНІ ФРАЗЕОЛОГІЧНІ ОДИНИЦІ УКРАЇНСЬКОЇ, ПОЛЬСЬКОЇ ТА АНГЛІЙСЬКОЇ МОВ НА ПОЗНАЧЕННЯ ЕМОЦІЙ
Authors: ПАТЕН Ірина
Published: February 2020

У статті р озглянуто компаративні фразеологічні одиниці на позначення емоцій української, польської та англійської мов, з’ясовано, що емоції є предметом вивчення не лише філософії, психології чи фізіології, а й лінгвістики; зазначено, що компаративна фразеологія ґрунтується на переосмисленому стійкому порівнянні, а порівняння – це основа людського мислення, спосіб пізнання людини і світу; обґрунтовано, що носії обстежуваних мов найчастіше використовують компаративні фраземи для вираження негативних емоцій, адже людство в першу чергу звертає увагу на недоліки і таким чином вдосконалюється за допомогою критики та іронії, а позитивні емоції не викликають такої гострої реакції, тож відповідних компаративних фразем є небагато.

ЛEКСИКА НА ПОЗНАЧЕННЯ РЕЛІГІЙНИХ ПОНЯТЬ В РОМАНІ «РАЙ» В. БАРКИ
Authors: ПИШНА Наталія
Published: February 2020

Письменник-емігрант В. Барка підтверджує, що в роки, в які він жив і працював, не було змоги через культурно-релігійні, суспільно-політичні причини писати твори з християнською проблематикою в Україні, а лише за кордоном. Роман “Рай” В. Барки насичений релігійними номінаціями, які в статті диференційовано на різні лексико-семантичні підгрупи та проаналізовано. З’ясовано, що автор обстежуваного твору неодноразово ілюструє демонологічну лексику, вживає її на позначення злої сили та збагачує твір релігійними синонімійними та антонімійними номенами.

ЦИТАТНО-РЕМІНІСЦЕНТНИЙ (ІНТЕРТЕКСТУАЛЬНИЙ) ВИМІР ПОЕТИЧНОГО ДИСКУРСУ МАЙДАНУ
Authors: СТЕЦИК Марія
Published: February 2020

У статті майданівські поетичні тексти досліджуються крізь призму рецептивної стилістики (інтертекстуальності), тобто їхньої смислової багатошаровості (цитати, натяки, алюзії, ремінісценції). Зазначено, що актуалізований націєцентричний цитатний тезаурус – це вищий, художньо опосередкований рівень побутування дискурсу, який, з одного боку, засвідчує авторську майстерність, інтелектуалізм та органічну рецептивну асоціативність мовомислення, з іншого – вимагає підготовленого читача, реципієнта з багатим літературно-художнім та загальнокультурним досвідом. Розлогий цитатно-ремінісцентний та алюзивно-алегоричний простір майданівської поезії спростовує тезу про те, що це література факту невисокої художньої вартості.
