The Information Effect of Monetary Policy: Self-Defeating or Optimal?
Authors: Janson Wesley , Jia Chengcheng
Published: July 2020

As the Federal Reserve has become more transparent about its decisions on the federal funds target rate, the general public has begun to regard the rate as not only a benchmark interest rate, but also as a signal about the state of the economy. However, the specific information considered by the public to be revealed is not clearly understood. We investigate this question and find that the information revealed by monetary policy decisions is regarding future output growth, not inflation, and that such an information effect is theoretically optimal and does not make interest-rate policies self-defeating.
Implementation of the user-centered design (ucd) method for designing web marketplace of qurban cattle sales in indonesia
Authors: Rahmawati Endra
Published: July 2020

This study aims to create a user interface design for the designing web marketplace of qurban cattle sales in East Java, Indonesia. The word qurban referred as  the qurban animal slaughtered during the Eid al-Adha, especially cow.  The qurban web market can help breeders and customers in the process of selling cattle directly without limited territory.  This is because the process of selling qurban cows is still done traditionally by ordering directly by phone and coming directly to the cattle pen for the selection of qurban animals desired by consumers. To deal with these problems, an alternative solution is needed that can create a Web Marketplace interface design that is designed using the User-Centered Design (UCD) method, focusing on the user's primary needs. This method was chosen because it focuses on the user's goals, characteristics, and workflow in the design process. How the system can be understood and used by users is a top priority in this web design and involves users in designing the marketplace web interface. Therefore it is very suitable for designing a website that is simple and easy to use. The design of the web marketplace of qurban cattle sales has four main features which are promotion of qurban cattle, online qurban cattle bookigs (direct purchases or livestock care services), payment confirmation, and qurban cattle contributions for collective purchases or in groups. The results of the System Usability Scale (SUS) test distributed to 30 respondents obtained a value of 79.3 which indicates that the qurban web marketplace design can be accepted by users and can be classified as good design.
Leaving no one behind: Community Management of At-risk Mothers and Infants under six months (MAMI) in the context of COVID-19 in Gambella refugee camps, Ethiopia
Authors: Rana Ritu , Barthorp Hatty , Murphy Mary T
Published: July 2020

Refugees are at an increased risk of contracting Coronavirus disease (COVID-19) due to their suboptimal living environment and inadequate access to healthcare services. As refugee-hosting countries are preparing to prevent and contain the spread of COVID-19 infections by diverting healthcare efforts, it is equally important to prevent the collapse of existing lifesaving services, including those provided during the first 1,000 days (nutrition services from conception to a child’s second birthday).  

Recently, many international organisations, including United Nations agencies, have published guidance documents for programming in refugee context. Similarly, there is global guidance available for nutrition programs in the context of COVID-19, such as -infant and young child feeding, management of child wasting, and nutrition information management; however, no specific guidance is available for community management of nutritionally at-risk mothers and infants under six months (MAMI).

In response to the major refugee influx, mainly women and children, from South Sudan, GOAL, an international humanitarian response organisation, is implementing a MAMI program since 2014. GOAL believes, despite COVID-19 context, it is critical to continue the MAMI program with adaptive measures to prevent and manage malnutrition among at-risk mothers and infants. In this regard, considering available international guidelines, both nutrition and refugee context-specific, GOAL has developed its own guidelines for the refugee population.

In this article, we present GOAL Ethiopia’s COVID-19 response within nutrition support services, for the South Sudanese refugees, focused on at-risk mothers with infants under six months, living in two Gambella refugee camps. We believe our guidelines will also be helpful for other organisations implementing MAMI in different contexts.

Authors: Amevinya Gideon S , Quarpong Wilhemina , Laar Amos
Published: July 2020

Background

Non-Communicable Diseases (NCDs) are a leading cause of death globally. NCD mortality attributable to unhealthy food environments (FEs) is significant. Heavy marketing of unhealthy foods is an important contributor to unhealthy FEs.

Aims

We examined the extent of commercial food advertising, messaging, and signage on the campus of Ghana’s oldest and largest university.

Methods

We cross-sectionally collected data on all sighted advertisements. Advertisements/signage were categorised as food or non-food adverts, and as healthy or unhealthy (if they were food).

Results

Of 503 advertisements recorded, 238 (47.3%) were food ads. Advertised food products were categorised as healthy (38.7%), unhealthy (57.6%), or other/miscellaneous (3.8%).  The most advertised food product was sugar-sweetened drinks (37.0%).   Different promotional techniques deployed included the use of claim pronouncement, promotional characters, emotional appeal, premium offer, and price promotion.

Conclusions

The preponderance of unhealthy food advertising on the campus of Ghana’s largest university has public health implications. Advertising may influence purchasing behaviour and consumption of unhealthy foods. Publicity and advocacy that motivate development of local policies to regulate various food promotion activities within this, and other Ghanaian food environments are urgently needed.

Authors: Nep EI , Carnachan Susan , Ngwuluka NC , Kontogiorgos V , Morris GA , Sims Ian , Smith AM
Published: July 2020

© 2016 Elsevier Ltd A polysaccharide from the leaves of Sesamum radiatum was extracted by maceration in deionized water followed by ethanol precipitation then chemically and physically characterised. Monosaccharide composition and linkages were determined by high performance anion exchange chromatography (HPAEC), gas chromatography–mass spectrometry (GC–MS) and nuclear magnetic resonance (NMR) spectroscopy respectively. Sesamum gum was composed of glucuronic acid, mannose, galactose, and xylose with trace quantities of glucose, rhamnose and arabinose. Proton and 13C NMR spectroscopy, and linkage analysis revealed a glucuronomannan based structure comprising a backbone of →4)-β-D-GlcpA-(1 → 2)-α-D-Manp-(1→ with side-chains of galactose and xylose. Hydrated sesamum gum displayed temperature independent viscoelastic properties with no thermal hysteresis. Intrinsic viscosity was determined to be 3.31 and 4.40 dL g−1 in 0.1 M NaCl and deionised water respectively, while the critical concentration was determined to be 0.1% w/v. The characterisation performed in this study will help direct potential applications of this material in foods and pharmaceuticals.
Alginate polymerization and modification are linked in pseudomonas aeruginosa
Authors: Moradali M Fata , Donati I , Sims Ian , Ghods S , Rehm BHA
Published: July 2020

© 2015 Fata Moradali et al. The molecular mechanisms of alginate polymerization/modification/secretion by a proposed envelope-spanning multiprotein complex are unknown. Here, bacterial two-hybrid assays and pulldown experiments showed that the catalytic subunit Alg8 directly interacts with the proposed copolymerase Alg44 while embedded in the cytoplasmic membrane. Alg44 additionally interacts with the lipoprotein AlgK bridging the periplasmic space. Site-specific mutagenesis of Alg44 showed that protein-protein interactions and stability were independent of conserved amino acid residues R17 and R21, which are involved in c-di-GMP binding, the N-terminal PilZ domain, and the C-terminal 26 amino acids. Site-specific mutagenesis was employed to investigate the c-di-GMP-mediated activation of alginate polymerization by the PilZAlg44 domain and Alg8. Activation was found to be different from the proposed activation mechanism for cellulose synthesis. The interactive role of Alg8, Alg44, AlgG (epimerase), and AlgX (acetyltransferase) on alginate polymerization and modification was studied by using site-specific deletion mutants, inactive variants, and overproduction of subunits. The compositions, molecular masses, and material properties of resulting novel alginates were analyzed. The molecular mass was reduced by epimerization, while it was increased by acetylation. Interestingly, when overproduced, Alg44, AlgG, and the nonepimerizing variant AlgG(D324A) increased the degree of acetylation, while epimerization was enhanced by AlgX and its nonacetylating variant AlgX(S269A). Biofilm architecture analysis showed that acetyl groups promoted cell aggregation while nonacetylated polymannuronate alginate promoted stigmergy. Overall, this study sheds new light on the arrangement of the multiprotein complex involved in alginate production. Furthermore, the activation mechanism and the interplay between polymerization and modification of alginate were elucidated.

Evaluation of some important physicochemical properties of starch free grewia gum
Authors: Nep EI , Sims Ian , Morris GA , Kontogiorgos V , Smith AM
Published: July 2020

© 2015 Elsevier Ltd. Gums obtained by extraction from the inner bark of stems can be found in association with starch, which must be digested in order to obtain a refined polysaccharide isolate. In the present study, grewia gum obtained from the inner bark of the stems of Grewia mollis was shown to co-exist with starch and the effect of starch digestion on the physicochemical properties of the resultant polysaccharide was evaluated. The gum was extracted by maceration of the inner bark in deionised water and isolated by a combination of filtration, centrifugation and finally precipitation with absolute ethanol to produce the crude grewia gum extract (GG). The presence and content of starch in the gum sample was determined followed by enzymatic digestion of the starch using a-amylase (Termamyl 120L) to give a starch-free extract (GGDS). Physicochemical properties of the extracts such as total carbohydrates, total protein, differential sugar composition, NMR, intrinsic viscosity and rheological behaviour of the samples were evaluated. The GG extract had total carbohydrate content of ~60% out of which 11.8% was starch, and a protein content of 2.3%. Samples also contained galacturonic and glucuronic acid which were highly acetylated. Both samples had a higher proportion of galacturonic acid than glucuronic acid and contained rhamnose, arabinose, galactose, glucose and xylose as neutral sugars in varying proportions. Rheological measurements on 2%w/w dispersions of the extracts show minor differences between both the original extract and the de-starched material but were influenced by changes in pH.
Monoglobus pectinilyticus gen. nov., sp. nov., a pectinolytic bacterium isolated from human faeces.
Authors: Kim CC , Kelly WJ , Patchett ML , Tannock GW , Jordens Z , Stoklosinski HM , Taylor JW , Sims Ian , Bell Tracey , Rosendale DI
Published: July 2020

© 2017 IUMS. A novel anaerobic pectinolytic bacterium (strain 14T) was isolated from human faeces. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain 14T belonged to the family Ruminococcaceae, but was located separately from known clostridial clusters within the taxon. The closest cultured relative of strain 14T was Acetivibrio cellulolyticus (89.7% sequence similarity). Strain 14T shared ~99% sequence similarity with cloned 16S rRNA gene sequences from uncultured bacteria derived from the human gut. Cells were Gram-stain-positive, non-motile cocci approximately 0.6μm in diameter. Strain 14T fermented pectins from citrus peel, apple, and kiwifruit as well as carbohydrates that are constituents of pectins and hemicellulose, such as galacturonic acid, xylose, and arabinose. TEM images of strain 14T, cultured in association with plant tissues, suggested extracellular fibrolytic activity associated with the bacterial cells, forming zones of degradation in the pectin-rich regions of middle lamella. Phylogenetic and phenotypic analysis supported the differentiation of strain 14T as a novel genus in the family Ruminococcaceae. The name Monoglobus pectinilyticus gen. nov., sp. nov. is proposed; the type strain is 14T (JCM 31914T=DSM 104782T).
Structural analysis of oligomeric fructans from excised leaves of Lolium temulentum
Authors: Sims Ian , Pollock CJ , Horgan R
Published: July 2020

Individual fructan tri-, tetra- and pentasaccharide isomers in neutral, water-soluble extracts from Lolium temulentum were purified and the linkages present in these isomeric oligosaccharides were analysed by combined GC-mass spectrometry of partially methylated alditol acetates. 1-Kestose and neokestose were the most abundant trisaccharides with 6-kestose present in much lower amounts. Analysis of isomers of DP 4 and 5 showed that multiple linkage types were present with structures based on all three trisaccharides. Oligosaccharides based on neokestose but with 2,6 linkages between adjacent fructose residues have not been previously detected in higher plants. © 1992.
Extracellular polysaccharides from suspension cultures of Nicotiana plumbaginifolia
Authors: Sims Ian , Bacic A
Published: July 2020

The soluble polymers secreted by cell-suspension cultures of Nicotiana plumbaginifolia contained 78% carbohydrate, 6% protein and 4% inorganic material. The extracellular polysaccharides were separated into three fractions by anion-exchange chromatography using a gradient of imidazole-HCl at pH 7 and the individual polysaccharides in each fraction were then isolated by selective precipitation and enzymic treatment. Monosaccharide and linkage compositions were determined for each polysaccharide after reduction of uronic acid residues and the degree of esterification of the various uronic acid residues in each polysaccharide was determined concurrently with the linkage types. Six components were identified: an arabinoxyloglucan (comprising 34% of the total polysaccharide) and a galactoglucomannan (15%) in the unbound neutral fraction, a type II arabinogalactan (an arabinogalactan-protein, 11%) and an acidic xylan (3%) in the first bound fraction, and an arabinoglucuronomannan (11%) and a galacturonan (26%) in the second bound fraction. © 1995.

Authors: Nunan KJ , Sims Ian , Bacic A , Robinson SP , Fincher GB
Published: July 2020

Cell walls were isolated from the mesocarp of grape (Vitis vinifera L.) berries at developmental stages from before veraison through to the final ripe berry. Fluorescence and light microscopy of intact berries revealed no measurable change in cell wall thickness as the mesocarp cells expanded in the ripening fruit. Isolated walls were analyzed for their protein contents and amino acid compositions, and for changes in the composition and solubility of constituent polysaccharides during development. Increases in protein content after veraison were accompanied by an approximate 3-fold increase in hydroxyproline content. The type I arabinogalactan content of the pectic polysaccharides decreased from approximately 20 mol % of total wall polysaccharides to about 4 mol % of wall polysaccharides during berry development. Galacturonan content increased from 26 to 41 mol % of wall polysaccharides, and the galacturonan appeared to become more soluble as ripening progressed. After an initial decrease in the degree of esterification of pectic polysaccharides, no further changes were observed nor were there large variations in cellulose (30-35 mol % of wall polysaccharides) or xyloglucan (approximately 10 mol % of wall polysaccharides) contents. Overall, the results indicate that no major changes in cell wall polysaccharide composition occurred during softening of ripening grape berries, but that significant modification of specific polysaccharide components were observed, together with large changes in protein composition.
An Assessment of Public Opinion in Balochistan about Federal Form of Government in Pakistan
Authors: Abdul Basit Khan  , Ali Shan Shah  , Tariq Aziz  , Mian Muhammad Azhar
Published: July 2020

Almost every state or society particularly a pluralistic one is composed of various nationalities or sub-national groups whereas every segment has its own distinct identity being a source of pride and strength for its survival. In relatively homogenous societies, the process of nation-building though not easy is at least less cumbersome whereas in pluralistic societies this process demands a lot of hard work on the part of the elite who must exhibit vision, wisdom, foresight and patience; because such societies are always fraught with the danger that any of the nationalities or sub-national group may dominate the others. The societies having a considerable level of social, cultural and linguistic heterogeneity hence horizontally/vertically divided and cross-divided in the pursuit of their distinct preferences and priorities can hardly be united under a single administrative structure nevertheless they can be persuaded to form a union under some common government.  For this purpose, a federal arrangement may be suitable option because it provides for unity in diversity rather than unity in its absolute terms. The federation of Pakistan, since its vey inception, is struggling to create the said unity particularly with reference to the situation in Balochistan which is facing a long and multi-faceted unrest posing a substantial challenge for the federation. The present study empirically explores the nature of grievances of the people of Balochistan with respect to the federation of Pakistan by conducting a field survey and establishes that majority of the people of Balochistan do not believe that the federal design in Pakistan is functioning in its true letter and spirit with reference to Balochistan.
Flank Wear Modelling in High Speed Hard Milling of AISI D2 Steel
Authors: Al Hazza Muataz , Muhammad Khadijah
Published: July 2020

High speed machining has many advantages in reducing time to the market by increasing the material removal rate. However, final surface quality is one of the main challenges for manufacturers in high speed machining due to the increasing of flank wear rate. In high speed machining, the cutting zone is under high pressure associated with high temperature that lead to increasing of the flank wear rate in which affect the final quality of the machined surface. Therefore, one of the main concerns to the manufacturer is to predict the flank wear to estimate and predict the surface roughness as one of the main outputs of the machining processes. The aim of this study is to determine experimentally the optimum cutting parameters: depth of cut, cutting speed (Vc) and feed rate (f) that maintaining low flank wear (Vb). Taguchi method has been applied in this experiment. The Taguchi method has been universally used in engineering analysis.  JMP statistical analysis software is used to analyse statically the development of flank wear rate during high speed milling of hardened steel AISI D2 to 60 HRD. The experiment was conducted in the following boundaries: cutting speed 200-400 m/min, feed rate of 0.01-0.05 mm/tooth and depth of cut of 0.1-0.2 mm. Analysis of variance ANOVA was conducted as one of important tool for statistical analysis. The result showed that cutting speed is the most influential input factors with 70.04% contribution on flank wear.

Father-child discourse in Family Guy: a corpus-based analysis
Authors: Sliepushova Anhelina
Published: July 2020

The article aims at analysis of gender and family stereotypes in father-child communication in an animated series Family Guy, featuring a typical American family. The study focuses on Peter Griffin's discourse, the father of the family, containing his communication with two of his teenage children, a son and a daughter, unveiling gender peculiarities in father-son and father-daughter discourses. The attempt is made to disclose how gender and family roles are verbalized in communication between family members. The conversation, discourse and corpus-based analyses have been used to analyze the main character's discourse in order to single out the father's specific vocabulary — through word lists, keyword lists, clusters and collocations — he uses while communicating with his son and daughter. The findings show that Peter Griffin chooses different language means while talking to his son and daughter. Thus, his discourse addressing his adolescent son Chris is rich in direct addresses, mainly commands when the father tries to discipline his son. Offering his son emotional support or encouragement the father stays forthright with him creating an image of “real men” stereotypical conversations. On the contrary, while communicating with his daughter Peter modifies her name Meg addressing her as honey, sweetheart, one-of-a-kind in father-daughter discourse. However, using diminutives he humiliates his daughter and makes her feel an abandoned child. In this way, he makes her feel special but in a negative way. Family communication created in the animated series reflects gender stereotypes in father's attitude to his children belonging to two different sexes. Nevertheless, this verbal tendency does not affect relationships within the family. For the future, it is worthwhile to compile a larger corpus including mother-child, child-father, and child-mother discourses to get more representative results
Macroscopic Traffic Flow Characterization at Bottlenecks
Authors: Iftikhar Amir , Khan Zawar H. , Gulliver T. Aaron , Khattak Khurram S. , Khan Mushtaq A. , Ali Murtaza , Minallahe Nasru
Published: July 2020

Traffic congestion is a significant issue in urban areas. Realistic traffic flow models are crucial for understanding and mitigating congestion. Congestion occurs at bottlenecks where large changes in density occur. In this paper, a traffic flow model is proposed which characterizes traffic at the egress and ingress to bottlenecks. This model is based on driver response which includes driver reaction and traffic stimuli. Driver reaction is based on time headway and driver behavior which can be classified as sluggish, typical or aggressive. Traffic stimuli are affected by the transition width and changes in the equilibrium velocity distribution. The explicit upwind difference scheme is used to evaluate the Lighthill, Whitham, and Richards (LWR) and proposed models with a continuous injection of traffic into the system. A stability analysis of these models is given and both are evaluated over a road of length 10 km which has a bottleneck. The results obtained show that the behavior with the proposed model is more realistic than with the LWR model. This is because the LWR model cannot adequately characterize driver behavior during changes in traffic flow.

Rectangular Hollow Sections (RHS) because of their high resistance to tension, as well as compression, are commonly used as a bracing member with slotted gusset plate connections in steel structures. Since in this type of connection only part of the section contributes in transferring the tensile load to the gusset plate, shear lag failure may occur in the connection. The AISC specification decreases the effective section net area by a factor to consider the effect of shear lag for a limited connection configuration. This study investigates the effective parameters on the shear lag phenomenon for rectangular hollow section members connected at corners using a single concentric gusset plate. The results of the numerical analysis show that the connection length and connection eccentricity are the only effective parameters in the shear lag, and the effect of gusset plate thickness is negligible because of the symmetric connection. The ultimate tensile capacity of the suggested connection in this study were compared to the typical RHS connection presented in the AISC and the similar double angle sections connected at both legs. The comparison indicates that tensile performance of the suggested connection in this study because of its lower connection eccentricity is much higher than the typical slotted connection and double angle connections. Therefore, a new equation is suggested based on the finite element analyses to modify the AISC equation for these connections.

Published: July 2020

Whenever a member of a structure becomes structurally deficient, it becomes vulnerable to the existing load and for the additional loads that it may be subjected to in the coming future. Since columns are the most important structural element, the structural retrofit of columns, relative to other structural elements is of prime importance. This study intends to investigate the performance and behaviour of an RC column jacketed with Reinforced Concrete columns under axial loads. The objective of this paper is to find out the efficiency of RC jacket in enhancing the strength of an existing RC column. A mathematical design based upon Indian Standards codes has been designed to identify the behaviour of jacketed RC columns. This has been followed by a finite element based numerical simulation using the same material properties as used in the process of designing. The simulation has been done in ABAQUS software with appropriate contact modelling. The analytical model considers that there is no bond slippage between the existing and new concrete surface i.e. the bond between the existing and new concrete is assumed to be perfect. This perfect bond between the surfaces has been modelled by using appropriate constraints in ABAQUS software. The finite element models show fair agreement with the designed values in terms of ultimate capacity and failure mode. The load bearing capacity enhancement of the RC jacketed column has been found to increase substantially. The enhancement capacity results obtained from the finite element software differs about 16-25% from the design values.

In terms of recycling and reuse, today's global generation of waste tire well exceeds its consumption. This has resulted in the accumulation of large stocks of toxic rubber waste that raise health and safety risks. The use of waste tire rubber for the construction of the concrete structure was suggested to combat this challenge. This paper explores tests that were performed with samples of waste tire rubber concrete to evaluate compressive strength, flexural tensile strength, modulus of rupture, and impacts resistance. The main parameters investigated were the rubber ratio as a partial volumetric replacement with fine and coarse aggregate. Chip and crumb rubbers were used to replace coarse and fine aggregate respectively in four different amounts by volume (5%, 10%, 15%, and 20%). Even if the inclusion of waste tire rubber in concrete has specific apparent degradations, the potential benefit seems to overlook the adverse effects and also meet the primary significant value of resolution for rubber waste utilization problems. The results show that the substitution of natural fine or coarse aggregates with crump-chip tier rubber will reduce mechanical properties (compressive, flexural and splitting tensile strength), but increase the impacts resistance to 426% and 396% when 20% coarse aggregates and 20% fine aggregates are replaced by rubber respectively. The proposed mix shows an ability to replace 20% of the aggregate (coarse or fine), and the producing, rubcrete, still structural concrete.

La investigación se realizó en la provincia de Pichincha, cantón Quito, Parroquia Nayón, cuya temperatura varía entre 18°C a 22°C y se encuentra a una altitud de 2325 msnm. La guaba es una especie utilizada para brindar sombra en algunos cultivos como el café y cacao. En este estudio se seleccionaron 15 árboles de guaba en los cuales se marcaron 30 yemas vegetativas/planta para seguirlas en el tiempo y observar su desarrollo. Se realizaron observaciones semanales del paso de las fenofases vegetativa a reproductiva del cultivo para establecer la duración de cada una y la actividad térmica necesaria para que estos cambios se puedan dar.
Durante el estudio los árboles de guaba seleccionados presentaron brotación, caída del follaje y fructificación constante. Estos cambios variaron dependiendo las condiciones climáticas de Nayón. Con los resultados obtenidos finalmente se determinó que la etapa de floración duró 155 días para el cultivo de guaba y un total de 497 unidades térmicas necesarias para cosechar frutos.
La escala BBCH (Biologische Bundesanstalt, Bundessortenamt und Chemische Industrie) describe el desarrollo fenológico de los cultivos desde la germinación hasta la senescencia, comprende 8 etapas principales que son la germinación, desarrollo de las hojas, formación de brotes, aparición de inflorescencias, floración, desarrollo de los frutos, maduración de frutos y senescencia. En base a esta escala se desarrolló una descripción fenológica visual de la guaba de la fase de floración y desarrollo del fruto con las subfases más importante visualizadas (521, 525, 529, 621, 625, 629, 723, 725, 729). Esta información básica y de gran utilidad constituye un fundamento clave para comprender mejor el proceso de desarrollo de este cultivo y mejorar las prácticas de campo y producción.

La migración de metales hacia los alimentos es un tema concerniente a la inocuidad alimentaria y la ingesta dietética es una fuente importante de exposición no ocupacional al aluminio. En esta investigación se determinó la cantidad de aluminio que se transfiere desde las ollas al preparar colada de avena con naranjilla (Solanum quitoense), bebida con pH ácido consumida ampliamente en Ecuador. Su preparación se realizó en ollas de aluminio de cinco marcas comercializadas en Quito y durante siete ciclos de cocción. La cuantificación de la concentración de aluminio transferido a las ciento cuarenta muestras de colada se realizó por espectroscopia de absorción atómica con llama de óxido nitroso-acetileno. Las concentraciones de aluminio transferido al alimento durante los siete tratamientos sobrepasan el límite permisible de 1 mg Al/kg establecido por la Unión Europea (Reglamento Europeo UE 1416:2016), excepto para la marca de olla IV que en el séptimo tratamiento presenta 0,76±0,04 mg Al/kg. El análisis de varianza ANOVA de dos factores indica que las marcas de las ollas y el número de tratamientos aplicados sí afecta estadísticamente a la migración de aluminio.

All powered vehicles have a braking system adopted according to the type of vehicle and work for which they are designed. In Ecuador, there is a great variety of auto parts that are proposed as alternative replacement, varying in cost and quality. This research aims to quantitatively analyze the characteristics of the brake disc material between original and alternate auto parts. This research analyzes three brake disc samples (A, B, C) from different manufacturing sources, using the ASTM E415-08 spectrometry test and the metallography test under the ASTM A247-16A standard. The spectrometry detects 15 elements in each sample, the carbon equivalent of sample A is 18% and 20% higher in relation to sample B and C, which significantly influences the microstructure. The metallographic tests indicate a pearlitic matrix in each sample, however, there is a different distribution and size of the graphite flakes. According to the SAE J431 standard, each auto part meets the material conditions for the brake disc function.

Прецедентні релігійні феномени як інтертекстеми в художній прозі Марії Матіос: лінгвостилістичний вимір
Authors: Берестова Алла
Published: July 2020

У пропонованій статті проаналізовано релігійні інтертекстеми, представлені в таких прозових творах Марії Матіос, як «Апокаліпсис», «Армагедон уже відбувся», «Майже ніколи не навпаки», «Мама Маріца», «Черевички Божої Матері». Вибір теми пояснюється тим, що дотепер особливості функціонування прецедентних релігійних феноменів як інтертекстових елементів у творчому доробку письменниці були обійдені увагою мовознавців. Автор розвідки доходить висновку про те, що в опрацьованих художніх творах активно вживаються прецедентні релігійні феномени (імена, висловлення, тексти, ситуації) в «канонічній» і модифікованій формах. У заголовках і в оповідній тканині досліджувані мовні одиниці виступають як інтертекстеми, що актуалізуються за допомогою текстових алюзій, текстових аплікацій і цитування й виконують сигнально-інформативну, організаційно-композиційну функції, а також функції налаштування, емоційного насичення й традиційно-звичаєвої ідентифікації.
