Authors: Pereira Adalmiro , Pereira Ana , Queirós Mario
Published: July 2021

A principal razão indicada para as fusões e aquisições (F&A) que se tem verificado nos últimos vinte anos, é a criação de valor para os acionistas e para a entidade. Vários autores escreveram sobre este tema e se todos concluem que as F&A devem criar valor, na prática tal poderá não se verificar. Por esta razão, achou-se pertinente realizar este estudo, sendo o principal objetivo verificar se as F&A criam realmente valor ou não, para os investidores e organizações envolvidas. A amostra recolhida tem por base algumas F&A registadas no setor Bancário Português. Num primeiro ponto, identificou-se algumas das variáveis estratégicas utilizadas pelos bancos envolvidos na transação. Em seguida, averiguou­‑se se existiu uma criação de valor ou não nos bancos envolvidos no processo de F&A. Depois de se elaborar o estudo, concluiu­‑se que a maioria das fusões abordadas neste estudo criaram valor e que não existe nenhuma relação entre a similaridade estratégica e a criação de valor. Tendo em conta os resultados obtidos, foram mencionadas, ainda, algumas sugestões para a realização de trabalhos futuros.

Edu-Crafting Teacher Identities
Authors: Hostetler Angela
Published: July 2021

“Teacher identity” is a popular topic for discussion and reflection in teacher education. We ask pre-service teachers to consider cultural and personal images of teachers (as expert, caregiver, authoritarian, and so on) in order to accept or resist these images as they contribute to the construction of their own teacher identity. Discussed in theory and aspirational language, teacher identity appears to behave in a reasonably orderly fashion; however, once the novice teacher is introduced to the dynamic world of teaching, teacher identity can become an absolute mess to untangle. As an approach to research, posthumanism offers us a chance to see this mess as beautiful in its lively, evolving, and relational condition. This posthumanist project takes to heart that in order to understand concepts such as identity differently, we must also look differently. After Taylor (2018), who describes posthumanist research as “allowing oneself to be lured by curiosity, surprise, and wonder” (p. 377), I conduct a diffractive auto/ethnographic study of several teachers to find out what happens if I take seriously the value of play in research, wondering what can be gained, in terms of understandings of teacher identities, through cartomancy as a potential source of knowledge. Semetsky (2011) has introduced the use of tarot reading to education theory as a semiotic system that can be engaged with to transform education and heal the human psyche. In my own work, I have built a practice that takes cues from Semetsky and also departs from her work, in the spirit of research creation (Chapman and Sawchuk 2012), forging its own unique method and artistic path. Conducting interviews with five self-identified teachers through video conferencing, I host a dialogue between myself, the teacher, and the tarot cards; a combination of friendly discussion, formalized interview, and tarot reading take place. This unconventional approach to research allows me to give generous attention to these teachers’ identities by acknowledging their connections to other selves, other humans, and more-than-humans. I am particularly hoping to find an expanded sense of teachers' self-perception and an increased recognition of a teacher’s multiple, connected, changing, and changeable identities.

The integrals and integral transformations connected with the joint vector Gaussian distribution
Authors: Mukha V. S. , Kako N. F.
Published: July 2021

In many applications it is desirable to consider not one random vector but a number of random vectors with the joint distribution. This paper is devoted to the integral and integral transformations connected with the joint vector Gaussian probability density function. Such integral and transformations arise in the statistical decision theory, particularly, in the dual control theory based on the statistical decision theory. One of the results represented in the paper is the integral of the joint Gaussian probability density function. The other results are the total probability formula and Bayes formula formulated in terms of the joint vector Gaussian probability density function. As an example the Bayesian estimations of the coefficients of the multiple regression function are obtained. The proposed integrals can be used as table integrals in various fields of research.
Convective instability of air flows in the exhaust shaft above a four-row finned beam
Authors: Karlovich T. B. , Sukhotskii A. B. , Danilchik E. S.
Published: July 2021

Herein, multidirectional quasiperiodic air flows in an exhaust shaft above a four-order horizontal bundle consisting of bimetallic finned tubes used to remove heat in heat exchangers are considered. Modeling of the air movement is carried out on the basis of equations for thermogravitational convection in the Boussinesq approximation. It takes into account the viscosity of the air and the dependence of the air density on the temperature. An interpretation of quasiperiodic airstreams is proposed on the basis of Rayleigh – Bénard convection, as a result of which regular structures, called Rayleigh – Bénard cells, are formed in a liquid or gas. Rayleigh – Bénard cells are an analytical solution to the problem of the stability of hydrodynamics flows in the linear approximation. The appearance of two-dimensional (convective rolls) and threedimensional (rectangular cells) is possible. To estimate the number of emerging structures, the critical Rayleigh numbers were calculated, which characterizes the transition from an unstable mode of the convective fluid flow to a stable mode. For two experiments, the experimental Rayleigh numbers are compared with their critical values. The differences between the experimental conditions and the ideal boundary conditions used in the calculations and the partial destruction of quasiperiodic structures as a result of this are also discussed.
Inhibition of phospholipase A2 by Virasole derivation
Authors: Litvinko N. M.
Published: July 2021

Kinetics of phosphatidylcholine (PC) hydrolysis under the action of pancreatic phospholipase A2 IB, (EC 3.1.1.4, PLA2) in the presence of a lipophilic derivative of the antiviral drug Virazole 1-(3-((tert-butyldimethylsilyl)oxy)-4-hydroxy-5- (((4-methoxyphenyl)diphenylmethoxy)methyl)tetrahydrofuran-2-yl)-1H-1,2,4-triazole-3-carboxamide (Virazole2ЗГ) was studied. The both steps of phospholipolysis were quantitatively characterized: the binding of the enzyme to the lipid-water interface (Ks) and directly the catalytic act (Km) with the determination of the maximum reaction rate (Vmax). It was found that Virazole2ЗГ at a concentration of 0.5 μmol/ml does not affect the Ks value; on the contrary, the Michaelis constant, Km, increases by a factor of 1.8 along with the constancy of the parameter Vmax. Based on the constancy of the Ks values, it seems to be assumed that there is no inhibition of the disintegration of the enzyme-micelle complex in the presence of the effector under the studied reaction conditions. The kinetic parameters of the reaction (the increase in Km and the constancy of Vmax in the presence of Virazole2ЗГ) testify in favor of a moderate competitive inhibition of pancreatic PLA2, Ki = 65 mM, which indicates the possibility of searching for the biological activity of the anti-pancreatitis action in the series of pro-drugs of nucleoside nature.

Authors: Pasovets V. N. , Kovtun V. A. , Pleskachevsky Yu. M.
Published: July 2021

Tribotechnical tests and microstructural studies were carried out. Wear mechanism of nanostructured metalpolymer self-lubricating composite materials has been established. This mechanism involves in the formation of separating polymer layers on the friction surface, which reduces the coefficient of friction and running-in period of parts of friction units. Carbon nanoparticles move along the friction surface, hinder the development of seizure processes during the interaction of microroughnesses of the contacting surfaces of the material and the counterbody during the destruction of the separating polymer layers. It was found that the polymer filler is displaced from the friction zone, carbon nanoparticles are pressed into the open areas of the surface of the copper matrix of the composite when the pressure in the tribocontact is higher than 1.5 MPa. The temperature in the tribocontact increases, the polymer filler degrades, the carbon nanoparticles are removed from the friction zone, the strength properties of the composite decrease, the friction coefficient and the wear rate increase at a sliding speed above 1.5 m/s. The obtained research results can be used in mechanical engineering, transportation industry and power engineering.

Vacancy-oxygen complexes VnOm (n, m ≥ 1) in crystalline silicon are nucleation centers for oxygen precipitates, which are widely used as internal getters in modern technologies of production of silicon-based electronic devices and integrated circuits. For the controllable formation of oxygen precipitates in Si crystals in the technology processes the methods of determination of concentrations of the VnOm complexes are required. The aim of the present work was to find values of the calibration coefficients for determination of concentrations of the VnOm defects in Si from intensities of infrared (IR) absorption bands associated with the local vibrational modes (LVM) of these complexes. A combined electrical (Hall effect) and optical (IR absorption) study of vacancy-oxygen defects in identical silicon crystals irradiated with 6 MeV electrons was carried out. Based on the analysis of the data obtained, the values of the calibration coefficient for the determination of concentration of the vacancy-oxygen (VO) complex in silicon by the infrared absorption method were established: for measurements at room temperature (RT) – NVO = 8.5 · 1016 · αVO-RT cm–3, in the case of low-temperature (LT, Т ≡ 10 K) measurements – NVO = 3.5 · 1016 · αVO-LT cm–3, where αVO-RT(LT) are absorption coefficients in maxima of the LVM bands due to the VO complex in the spectra measured at corresponding temperatures. Calibration coefficients for the determination of concentrations of other VnOm (VO2, VO3, VO4, V2O and V3O) complexes and the oxygen dimer (O2) from an analysis of infrared absorption spectra measured at room temperature have been also determined.
Modeling of the mechanism of heterogeneous inhibition of the active flame centers of a jet burning system by fire extinguishing powder particles
Authors: Kitsak A. I.
Published: July 2021

The relevance of the work is due to the lack of a physical interpretation of the process of extinguishing jet burning systems with fire extinguishing powders, which is important for ensuring effective fire extinguishing at gas and oil complexes and hazardous chemical industries. A mathematical model of the reaction kinetics of heterogeneous inhibition of active flame centers of a jet burning system by fire extinguishing powder particles in an unsteady mode is considered in the approximation of a purely molecular transfer of matter in the reaction zone. The regularities of the mechanism of heterogeneous inhibition of the active flame centers by the particles of the extinguishing powder under conditions when the active particles of the combustion products participate not only in diffuse, but also in convective transport are established. It is shown, that the convective motion of the active flame centers increases the reaction rate of heterogeneous inhibition of their particles of the extinguishing agent. The results obtained allow us to optimize the conditions for the supply of fire extinguishing powder to the jet burning medium for effective flame suppression.

Abstract. Karabakh is one of the main regions in Azerbaijan where local water
resources are formed. The article calculated the water resources of the area using
the data of hydrological observation stations operating on the Karabakh rivers before
the occupation. For research and analysis of average annual water discharge, multiyear observation data of hydrological stations operating on the Karabakh rivers were
collected and integrated into the SpSS Statistics program. For the study multi-year
average observation data of 32 hydrological stations in 20 rivers were collected. In
order to determine the exact location of the hydrological stations operating in the
area, a map was compiled using the Geographic Information System with reference
to the fund and archive materials. In addition, hydrological zoning of the flow was
carried out depending on the orographic features of Karabakh. During the analysis,
two hydrological regions were identified. The first hydrological region is the Tartarchay-Guruchay hydrological region, and the second region is hakari-Oлchuchay
hydrological region.
As a result of the study, it was determined that the water resources of the Karabakh
rivers are 1.64 km3
, which is 5.31% of the total water resources of Azerbaijan. During
the implementation of water management measures in the area, in order to ensure
the water security of the area, the resource potential of atmospheric precipitation
and river flow for the area was analyzed and maps were compiled.

Yaşamak ve var olmak arasındaki ilinti ve birbirinin yerine kullanılabilecek kavramlar gibi görünseler de düşünsel arka planları, tarihsel süreçleri, gündelik hayatla ve özellikle varoluşçulukla ilişkileri irdelendiğinde ikisinin farklı olduğu görülür. Kavramların metinlerde ayrı konumlandırılmasını sağlayan bu farklılığın en önemli sebebi varoluşçuluktur. Sunduğu perspektifle varoluşçuluk, bu kavramların olduğu metinlerin arka planının iyi irdelenmesini, ilişkili oldukları kavramların ne olduğunu ve mahiyetini açımlayarak, metinlerdeki estetik ve katmanlı yapıyı ortaya çıkarmaya odaklanır.

Bu kavramlar arasındaki ilişkinin kesiştiği varoluşçuluğun konumu, başta felsefi, edebi sonrasında diğer metinlerde imgesel söyleyiş, çağrışım, yayılan ve derinleşen anlam katmanlarıyla göze çarpar. Bu metinlerin yazarlarıyla ilgili olarak birçok kişiden söz etmek mümkün. Fakat edebi sahada bu anlamda öne çıkan isimlerden biri İsmet Özel’dir. Şiir serüveninde bireyin varoluşunu sorgulayan söylemin yerleşikliği, Özel’i bu anlamda farklı kılar. Çünkü Özel’in söyleminde yaşam ile varolmak varoluş düzleminde farklı anlamlar ihtiva ederler. Yaşam, genel algı içerisinde ilk insandan günümüze değin kuralları olan, gündelik yaşamla ilintili olarak görünürken; varolmak, devinimle alakalı, öznenin eylemlerine yaslanan, tercihte bulunabilen, bireyin kimliğine vurgu yapan, özetle varoluşçulukla ilintili; bunlara ilaveten İslam geleneğine sıkça atıfta bulunan, söylemini bu kültürün üzerine inşa eden bir özelliktedir.

Bu çalışmada Özel’in Amentü ve Münacaat metinlerinden yola çıkılarak yaşamak ve varolmak kavramları bağlamında varoluşçuluk tartışılmıştır.

Published: July 2021

One of the company's efforts in implementing the commitment to customer satisfaction is carried out through continuous improvement activities. All indicators are evaluated to determine the level of quality stability against process variations that will impact non-compliance with predetermined product specifications. One of the quality problems found in the tire manufacture industry is the out-percentage of tire uniformity, which suddenly increases, one of which is the value of static balance. This study analyses the process variation factors that occur to take corrective and preventive actions through a series of Root Cause Analysis (RCA), Fault Tree Analysis (FTA), and Failure Mode and Effect Analysis (FMEA). Refers to the analysis result, it was found that there was a problem with the rubber film gauge variation at the manufacturing step of the steel breaker, one of the material components in the tire construction. Two main factors cause rubber film thickness variation:  rubber sticky with roll calendar, Radial Run Out (RRO) Roll Calendar out standard, and viscosity compound variation with 12 root problems found. The results of the improvements that have been made can effectively improve rubber film thickness variation, increase the Cpk level of steel breaker material from 0.82 to 1.91 and reduce the out percentage ratio of static balance by 54.65%.

Abstrak

Daging sapi merupakan salah satu komoditas strategis dengan harga yang cukup berfluktuasi. Fluktuasi harga daging sapi dapat berpengaruh terhadap produsen, konsumen, dan industri pengolahan daging sapi skala kecil. Besarnya perubahan harga daging sapi yang terjadi di suatu pasar dapat memengaruhi pasar lainnya dan dapat digunakan untuk mengetahui kekuatan suatu pasar. Kajian ini bertujuan untuk mengkaji volatilitas dan transmisi harga daging sapi di sentra konsumen Jakarta dan sentra produsen Bandung, Semarang dan Surabaya. Data yang digunakan adalah data harian daging sapi. Volatilitas harga harian daging sapi dianalisis dengan menggunakan model GARCH dan transmisi harga dikaji dengan menggunakan model VAR/VECM. Hasil kajian menunjukkan bahwa hanya harga daging sapi Jakarta yang memiliki volatilitas rendah namun persisten dalam jangka panjang. Perubahan harga daging sapi ditransmisikan dua arah dari Jakarta ke Bandung dan Semarang, dan hanya searah dari Jakarta ke Surabaya. Hasil analisis menunjukkan bahwa upaya stabilisasi harga daging sapi dapat dilakukan dengan menjaga ketersediaan daging sapi baik melalui impor (jangka pendek dan menengah) maupun upaya penyediaan bibit sapi dan sapi potong lokal dalam jangka panjang. Iklim usaha daging sapi yang kompetitif juga diperlukan agar ketidaksesuaian perubahan harga antar pasar dapat dikurangi.

Abstract

Beef is one of the strategic commodities with fairly fluctuating prices. Fluctuations in beef prices could affect producers, consumers, and small-scale beef processing industries. The magnitude of changes in beef prices that occur in a market could affect other markets and could be used to determine the strength of a market. The purpose of this paper is to examine the volatility and transmission of beef prices in the consumer centers of Jakarta and the production centers of Bandung, Semarang and Surabaya. The data used is the daily data of beef. Daily price volatility of beef was analyzed using the GARCH model and price transmission was assessed using the VAR/VECM model. The results of the study show that only Jakarta beef prices have low volatility but are persistent in the long term. Changes in beef prices are transmitted in two directions from Jakarta to Bandung and Semarang, and only in one direction from Jakarta to Surabaya. The results of the analysis show that efforts to stabilize beef prices could be carried out by maintaining the availability of beef either through import (short and medium term) or efforts to provide cattle seeds and local beef cattle in the long term. A competitive beef business climate is also needed so that discrepancies in price changes between markets could be reduced.

Published: July 2021

This study presents a description of a rhyolite lava-forming eruption, including the conduit system, degassing history during the lava flow dynamics. We examined the Pleistocene Shiroyama rhyolite lava on Himeshima Island, Japan. The lava is mainly characterized by locally developed obsidian. Based on the structural variation, the obsidian lithofacies correspond to the shallow conduit. The geological investigation and FTIR analyses showed that gas removal from the conduit magma proceeded via vesiculation, fracturing, and brecciation, allowing formation of the dense obsidian. Since the lava originally maintained some extent of water, the lava effervesced just after the effusion. This vesiculation resulted in pervasive bubble coalescence and the formation of abundant permeable pathways. The volcanic gasses escaped via those pathways, allowing collapse of the bubbles and deflation of the lava. AMS (anisotropy of magnetic susceptibility) results indicate that the lava spread concentrically.
Brassinosteroids Application Responses in Fruit Crops – A Review
Authors: Sharma Shashi K.
Published: July 2021

Brassinsteroids (BRs) are a class of novel plant hormones gaining importance as potential allies of agricultural development worldwide. Research findings on influences of exogenous BRs application on various aspects of growth and development like vegetative growth, flowering, fruit set, fruit growth, ripening, storage, and tolerance to various biotic and abiotic stresses in fruit plants’ have been reviewed and discussed. The molecular or biochemical aspects of BRs responses to modulate growth and productivity by activating or withholding enzymatic reaction of different biochemical pathways of fruit plants have been elaborated. BRs are involved in ripening and fruit quality development of climacteric and non-climacteric fruits; as per reports of many researchers, they improve fruit color, phenolics, anti-oxidant activities and post-harvest life of many fruits. Fruit cracking in litchi has been found to be significantly reduced due to BRs application. This group of plant hormones possess the capacity to negate genetoxicity and pesticidal residues in many horticultural crops; it reflects the extension of their uses in producing consumer-friendly fruits through BRs application.

Published: July 2021

The existence and sustainability of the ethbotanical plant species are among the most important resources for the world, especially considering hunger and economic contribution. Moreover, with the use of wild plant species for human and animal health for medical purposes, these plants’ importance are increasing. Therefore social awareness is important for the effective and sustainable use of the relevant species. The main reason for the emergence of this study is this social awareness. Here, we worked on Glechoma hederacea L., which we registered for the first time in Düzce in 2019 due to the environmental and socioeconomic impacts reported to us by the local people. The aims of this study to present the existence of G. hederacea, its habitats, some morphological, phenological data and the impact of the ethnobotanical use of the plant on its sustainability in native range. For this purpose, the plant was followed in Düzce central district between July 2019 and May 2020. As a result, it was determined that G. hederacea started flowering in March in Düzce and the flowering continued until the end of November. In Düzce, which is built on a plain, it has been determined that G. hederacea was widespread primarily in pastures, natural open areas, roadsides, open woodlands, tree edges, agricultural and urban habitats. Moreover, for the sustainability of the plant, it has been determined that villagers take some sub-regional measures against vegetation removal and even carry out small activities for plant propagation. However, the ratio between harvesting rate and planting is not sufficient. Considering this situation, awareness activities for G. hederacea as well as other plant species with ethnobotanical use and, when necessary, encouraging the production of the relevant native species for medical purposes will be useful.
