An Analysis of Resilience Planning at the Nexus of Food, Energy, Water, and Transportation in Coastal US Cities
Authors: Raub Kristin B. , Stepenuck Kristine F. , Panikkar Bindu , Stephens Jennie C.
Published: June 2021

Climate change poses increased risks to coastal communities and the interconnected infrastructure they rely on, including food, energy, water, and transportation (FEWT) systems. Most coastal communities in the US are ill-prepared to address these risks, and resilience planning is inconsistently prioritized and not federally mandated. This study examined the resilience plans of 11 coastal US cities to understand 1. How FEWT systems were considered within resilience plans and, 2. How nexus principles or elements critical to a nexus approach were incorporated within resilience plans. A “Nexus Index” was created to examine the incorporation of nexus principles, which included partnerships and collaborations, reference to other plans or reports, discussion of co-benefits, cascading impacts, and inclusion of interdisciplinary or cross-silo principles. These principles were used to score each action within the resilience plans. Results showed that only eight actions (1% of all actions across the 11 plans) focused on the connections among FEWT systems within the resilience plans. The transportation system was associated with the most actions, followed by the energy system, water system, and the food system. While FEWT systems were not consistently included, there was evidence from the Nexus Index that the plans included elements critical to a nexus approach, such as the inclusion of partnerships and reference to co-benefits with the actions they designed to build resilience. The heterogeneity among the systems that each plan emphasized reflects the heterogeneity among the challenges that each city faces. While context-specific differences in resilience plans across cities are expected, some consistency in addressing certain infrastructural needs and their nexus interactions may greatly benefit and improve the implementation of resilience planning.

Authors: Andrews Deborah , Newton Elizabeth J. , Adibi Naeem , Chenadec Julie , Bienge Katrin
Published: June 2021

The data centre industry (DCI) has grown from zero in the 1980s, to enabling 60% of the global population to be connected in 2021 via 7.2 million data centres. The DCI is based on a linear economy and there is an urgent need to transform to a Circular Economy to establish a secure supply chain and ensure an economically stable and uninterrupted service, which is particularly difficult in an industry that is comprised of ten insular subsectors. This paper describes the CEDaCI project which was established to address the challenge in this unique sector; this ground-breaking project employs a whole systems approach, Design Thinking and the Double Diamond methods, which rely on people/stakeholder engagement throughout. The paper reviews and assesses the impact of these methods and project to date, using quantitative and qualitative research, via an online sectoral survey and interviews with nine data centre and IT industry experts. The results show that the project is creating positive impact and initiating change across the sector and that the innovative output (designs, business models, and a digital tool) will ensure that sectoral transformation continues; the project methods and structure will also serve as an exemplar for other sectors.
Data-Driven Analysis on Inter-City Commuting Decisions in Germany
Authors: Chen Hui , Voigt Sven , Fu Xiaoming
Published: June 2021

Understanding commuters’ behavior and influencing factors becomes more and more important every day. With the steady increase of the number of commuters, commuter traffic becomes a major bottleneck for many cities. Commuter behavior consequently plays an increasingly important role in city and transport planning and policy making. Although prior studies investigated a variety of potential factors influencing commuting decisions, most of them are constrained by the data scale in terms of limited time duration, space and number of commuters under investigation, largely owing to their dependence on questionnaires or survey panel data; as such only small sets of features can be explored and no predictions of commuter numbers have been made, to the best of our knowledge. To fill this gap, we collected inter-city commuting data in Germany between 1994 and 2018, and, along with other data sources, analyzed the influence of GDP, housing and the labor market on the decision to commute. Our analysis suggests that the access to employment opportunities, housing price, income and the distribution of the location’s industry sectors are important factors in commuting decisions. In addition, different age, gender and income groups have different commuting patterns. We employed several machine learning algorithms to predict the commuter number using the identified related features with reasonably good accuracy.

Published: June 2021

In this comparative study, we investigated different influential factors of mobile-assisted language learning (MALL) for improving productive and receptive language learning skills. To do this, 100 scientific research papers were selected from the top and high-quality journals based on the implications of MALL in higher education language learning. Eight papers were selected according to the specific criteria to categorize the results based on language skills interpretation and technological concepts. Therefore, after thoroughly understanding proposed methodologies and comparing them properly, underlying assumptions about this phenomenon are elaborated, and holistic and sustainable solutions are provided to address this idea. The results of this analysis indicated that Mobile devices are being utilized extensively in developing countries, with vocabulary being the primary language learning area assisted by technology and yielding satisfactory results. According to the findings of this comparative study, LINE and WhatsApp would be of interest among university students to improve receptively (listening and reading) and productivity (writing and speaking), respectively. Moreover, the technology acceptance model (TAM) would be a prominent option for teachers to adapt their current and future educational programs instead of only in-person teaching to improve students’ learning quality.

Synergy Analysis of the Influence of the Connection Cone on the Thermal Distribution during Regeneration
Authors: Mu Mingfei , Dou Lizhuang , Aslam Jawad , Chen Bisheng
Published: June 2021

Diesel particulate filters (DPF) are typically used for particle filtration in vehicle exhausts after a treatment system. The monolith inside a DPF is a symmetrical column structure, frequently an axisymmetric cylinder structure where filtration and regeneration occur. Due to the complex structure before the symmetric monolith, the internal particle distribution is not uniform, which leads to an uneven temperature change when regeneration occurs. During thermal regeneration, the temperature field inside a DPF is affected by the particle load, exhaust temperature and exhaust flow. The relationship between the temperature gradient and velocity vector is also a key factor influencing regeneration performance. Based on the particle-loading test method, a bench for thermal distribution testing during regeneration was built. Via experiments and simulations, the temperature field in an axisymmetric monolith during particle combustion given an uneven particle distribution was analyzed. Through field synergy analysis of the temperature and velocity fields in the monolith, the influence of connection cones with different structures on heat transfer enhancement was studied. The results indicated that compared with a monolith with a conventional linear cone, the radial temperature gradient is 1.1 °C/mm lower, the area of enhanced regeneration is larger, and the regeneration rate is improved in the monolith with a streamlined cone.
Explicit Solutions of Initial Value Problems for Fractional Generalized Proportional Differential Equations with and without Impulses
Authors: Hristova Snezhana , Abbas Mohamed I.
Published: June 2021

The object of investigation in this paper is a scalar linear fractional differential equation with generalized proportional derivative of Riemann–Liouville type (LFDEGD). The main goal is the obtaining an explicit solution of the initial value problem of the studied equation. Note that the locally solvability, being the same as the existence of solutions to the initial value problem, is connected with the symmetry of a transformation of a system of differential equations. At the same time, several criteria for existence of the initial value problem for nonlinear fractional differential equations with generalized proportional derivative are connected with the linear ones. It leads to the necessity of obtaining an explicit solution of LFDEGD. In this paper two cases are studied: the case of no impulses in the differential equation are presented and the case when instantaneous impulses at initially given points are involved. All obtained formulas are based on the application of Mittag–Leffler function with two parameters. In the case of impulses, initially the appropriate impulsive conditions are set up and later the explicit solutions are obtained.

Published: June 2021

Wild yeasts isolated from the surface of apples were screened for antagonistic activity against Penicillium expansum, the main producer of the mycotoxin patulin. Three antagonistic yeasts (Y33, Y29 and Y24) from a total of 90 were found to inhibit P. expansum growth. Identification by ITS region sequence and characterization showed that three selected isolates of yeast should be different strains of Metschnikowia pulcherrima. Several concentrations of the selected yeasts were used to study their in vitro antifungal effectivity against P. expansum on Petri dishes (plates with 63.6 cm2 surface) whereas their potential activity on patulin reduction was studied in liquid medium. Finally, the BCA that had the best in vitro antifungal capacity against P. and the best patulin degradation capacity was selected to be assessed directly on apples. All the selected strains demonstrated antifungal activity in vitro but the most efficient was the strain Y29. Isolated strains were able to reduce patulin content in liquid medium, Y29 being the only strain that completely reduced patulin levels within 120 h. The application of Y29 as biocontrol agent on the surface of apples inoculated with P. expansum, inhibited fungal growth and patulin production during storage. Therefore, the results shown that this yeast strain could be used for the reduction of P. expansum and its mycotoxin in apples or apple-based products by adapting the procedure application.

Elderly residents in nursing homes are at very high risk of life-threatening COVID-19-related outcomes. In this report, an epidemiological and serological investigation of a SARS-CoV-2 outbreak in an Italian nursing home is described. Among the residents, all but one (19/20) were regularly vaccinated against SARS-CoV-2. In mid-February 2021, a non-vaccinated staff member of the nursing home was diagnosed with the SARS-CoV-2 infection. Following the outbreak investigation, a total of 70% (14/20) of residents aged 77–100 years were found positive. The phylogenetic analysis showed that the outbreak was caused by the SARS-CoV-2 variant of concern 202012/01 (the so-called “UK variant”). However, all but one positive subjects (13/14) were fully asymptomatic. The only symptomatic patient was a vaccinated 86-year-old female with a highly compromised health background and deceased approximately two weeks later. The subsequent serological investigation showed that the deceased patient was the only vaccinated subject that did not develop the anti-spike protein antibody response, therefore being likely a vaccine non-responder. Although the available mRNA SARS-CoV-2 vaccine was not able to prevent several asymptomatic infections, it was able to avert most symptomatic disease cases caused by the SARS-CoV-2 variant of concern 202012/01 in nursing home residents.
Ion-Exchange Technology for Lactic Acid Recovery in Downstream Processing: Equilibrium and Kinetic Parameters
Authors: Vecino X. , Reig M. , Valderrama C. , Cortina J. L.
Published: June 2021

The downstream processing for the separation and purification of lactic acid is a hot research area in the bio-refinery field due to its continuous growing market in different sectors, such as the food, cosmetic and pharmaceutical sectors. In this work, the use of ion-exchange technology for lactic acid recovery is proposed. For that, four anion exchange resins with different polymer structures and functional groups were tested (A100, MN100, A200E and MP64). The sorption process was optimized by the Box–Behnken factorial design, and the experimental data obtained in the sorption process were analyzed by using the response surface methodology and fitted at different isotherms and kinetics models. Moreover, regenerant type, contact time and solid/liquid ratio were evaluated in the desorption process. Results showed that the best resin for lactic acid removal was A100, at pH = 4, with a resin/lactic acid solution ratio of 0.15 g/mL during a maximum of 1 h, achieving 85% of lactic acid removal. Moreover, equilibrium data sorption of lactic acid onto A100 resin was fitted by a Langmuir isotherm and by a kinetic model of a pseudo-second order. In addition, in the desorption process, it was stablished that a resin/regenerant ratio of 0.15 g/mL during 30 min with 0.1 M of NaOH solution provided the best results (4.45 ± 0.08 mg/g).
Parameter Identification by High-Resolution Inverse Numerical Model Based on LBM/CMA-ES: Application to Chalk Aquifer (North of France)
Authors: Zouhri Lahcen , Kaidi Sami , Smaoui Hassan
Published: June 2021

The present paper proposes the numerical solution of an inverse problem in groundwater flow (Darcy’s equation). This solution was achieved by combining a high-resolution new code HYSFLO-LBM (Hydrodynamic of Subsurface Flow by Lattice Boltzmann Method), based on LBM, to solve the direct problem, and the metaheuristic optimization algorithm CMA-ES ES (Covariance Matrix Adaptation-Evolution Strategy) to solve the optimization step. The integrated optimization algorithm which resulted from this combination, HYSFLO-LBM/CMA-ES, was applied to the hydrogeological experimental site of Beauvais (Northern France), instrumented by a set of sensors distributed over 20 hydrogeological wells. Hydrogeological parameters measured by the sensors are necessary to understand the aquifer functioning and to serve as input data for the identification of the transmissivity field by the HYSFLO-LBM/CMA-ES code. Results demonstrated an excellent concordance between the integrated optimization algorithm and hydrogeological applied methods (pumping test and magnetic resonance sounding). The spatial distribution of the transmissivity and hydraulic conductivity are related to the heterogeneous distribution of aquifer formations. The LBM and CMA-ES were chosen for their proven excellent performance and lesser cost, in terms of both money and time, unlike the geophysical survey and pumping test. The model can be used and developed as a decision support tool for integrated water resources management in the region.
Electrochemical Processes for the Treatment of Hazardous Wastes Exemplified by Electroplating Sludge Leaching Solutions

Published: June 2021

The solidified landfill disposal of hazardous solid waste such as electroplating sludge in arid/semi-arid areas has potential risks and hazards. In this study, the electrochemical method was used to destroy the structures of metal complexes in electroplating sludge and release metal ions so that the organics were removed by direct mineralization in the anode while the metal was recovered in the cathode. A SnO2/Ti electrode was used as the anode during the electrolysis process. The effect of different current densities (10, 20, 30, 40, 50, 60 A/m2), different pH values (2, 3, 4, 5, 6), and the presence of chloride (0.1 or 0.2 M NaCl) and sulfate (0.1 or 0.2 M Na2SO4) on treatment were investigated. Under the optimal treatment conditions (current density = 50 A/m2, pH = 3), the removal rates of CODCr, TOC, and Ni2+ reached 88.01%, 85.38%, and 97.57%, respectively, with a metal recovery of 97.01%. Further studies showed that active chlorine and active persulfate generated in the presence of chloride and sulfate had less effect on the removal of organics, while hydroxyl radicals played a major role. The dilution of the leachate would be detrimental to electrochemical treatment. The by-products of organic chlorination were produced in low amounts, mainly CHCl3. This method can be used to treat electroplating sludge in various areas to recover valuable metals while removing organic pollutants, complying with the concept of sustainable development. This method provides a new solution for the treatment of metal-containing hazardous solid waste such as electroplating sludge from the perspective of practical application.
Import substitution in Russia: current state and prospects
Authors: Litvinov Evgenij Andreevich , Savinov Yuri Anatolievich , Taranovskaya Evgenia Vadimovna
Published: June 2021

Import substitution is a process of gradual displacement of foreign goods in the domestic market by analogues of domestic production. In Russia, the need to accelerate the development of national production of agricultural raw materials and food products has been discussed since the beginning of the second decade of this century, since the increasing share of foreign goods in the national consumption of products on the domestic market has become a signal of a violation of the country’s food security indicators. The State authorities made the appropriate necessary decisions, which were implemented. This issue became particularly relevant after 2014, when Russia suddenly faced sanctions against it from the United States and its NATO allies. This led to the adoption of the counter-embargo, stimulated the development and implementation of additional eff orts to develop import substitution in our country. In a fairly short period of time, our country has achieved very signifi cant results in increasing its independence from imports, primarily in the food market, in particular in eliminating the shortage of meat and dairy products. The domestic market has become fully secured due to the national production of poultry, pork, many types of vegetables, and confectionery. The national production of beef and dairy products has expanded. This made it possible to signifi cantly reduce the import supply of such goods. The authors consider and analyze the current trends and features of this process. For a number of food products, Russia has become a major exporter on the world market, capturing major positions in the world market of wheat, sunflower oil, fats, a number of other food products, as well as fertilizers. The demand for Russian food products on a large scale is presented by China, the countries of the Middle East, and North Africa. Nevertheless, there are still unresolved problems in the country, which the authors point out. In particular, it is necessary to make eff orts to reduce import supplies of seeds, seedlings, breeding cattle, highly specialized agricultural machines, food equipment, to expand the development or purchase of technologies for processing agricultural products, the production of food additives and other imported components for the processing industry. Of course, there will remain some types of tropical agriculture, which the country will continue to import, since it is impractical to develop their production in Russia for climatic reasons.

Published: June 2021

The article presents the results of the analysis and generalization of the experience of the development of agricultural cooperatives in Canada (a country with a centuries-old history of agricultural cooperation), its successful cooperative practices at various historical stages (including the present). Within the framework of the presented study, a number of important scientific conclusions were obtained, including: 1) generalization of trends in the evolution of Canadian farms (as active participants in agricultural cooperation) and characteristics of their current state; 2) specification of technological and organizational innovations undertaken by Canadian agricultural cooperatives to strengthen their competitive position; 3) identification of promising trends in the development of agricultural cooperation in Canada, reflecting both the essential transformations of the phenomenon under consideration (agricultural cooperative), and fluctuations of its environment; 4) determining the importance of using foreign (Canadian) cooperative experience for the development of agricultural cooperation in Russia. The presented material is distinguished by the novelty of approaches, the adequacy of the research tools used, and the representativeness of the statistical data used. The factors of the effective functioning of Canadian agricultural cooperatives scientifi cally substantiated in the study, as well as the basic principles of their modern models, are advisable to use (as international experience) in the development of the domestic system of agricultural cooperation in a modern (global, mobile, unstable, unpredictable) environment, taking into account its new challenges. The conclusions obtained in the course of the work and the conclusions proposed by the authors are of both scientific interest (for further theoretical and empirical research) and practical significance (for specialists interested in the creation and successful functioning of domestic agricultural cooperatives).
Subjetividad al otro lado de las murallas
Authors: Ávila Royert César Adolfo
Published: June 2021

Este artículo explora el modo en que durante la Antigüedad tardía fueron representados paisajes idealizados en descripciones literarias bajo la forma de ekphrasis tomando como punto de partida un pasaje del Fedro de Platón. Puede ser percibido cómo estas representaciones fuera de las ciudades (especialmente desiertos), se convierten en espacios privilegiados para la apropiación de la subjetividad y además una oportunidad para crear una nueva manera de considerar el conocimiento y la ética, a través de la figura social de los anacoretas y los padres del desierto, en consonancia con una matriz cosmológica particular. Este fenómeno es presentado como una intersección entre la tradición platónica y nuevas transformaciones en la sociedad tardoantigua. De la valoración del conocimiento generado adentro de las murallas de la ciudad en la Atenas de Platón, a la experiencia extramuros en paisajes abiertos, donde explorar la propia interioridad es el principal objetivo de miles de subjetividades que habitaban las afueras de varias ciudades posclásicas.
Periferia Novosecular del arte inespecífico en la obra Ó de Nuno Ramos
Authors: Acevedo Rendón Julián , Gil Blandón Manuela
Published: June 2021

Este artículo se origina en un proyecto realizado en el grupo de investigación “Literaturas marginales” (Marginalia) a través de la línea “Relecturas del canon literario”. La mirada está centrada en el panorama de la literatura contemporánea y su lugar dentro de la postautonomía del arte contemporáneo; en efecto, el canon literario sufre sobresaltos y modificaciones progresivas que conducen a la pérdida de especificidad en los fenómenos literarios y a la disolución de los lenguajes cristalizados.

El objetivo consiste en proyectar una postura investigativa sobre los problemas que forman parte del modo de organización de lo sensible en la literatura contemporánea (y que permitirían hablar de transformaciones y crisis de nociones hasta hace poco consideradas centrales para definir el arte, tales como pertinencia, especificidad y autonomía).

La conjetura converge con consideraciones de carácter crítico literario, filosófico, estético y sociológico, como: la obra literaria Ó (2008) del artista brasileño Nuno Ramos; la dimensión crítica literaria del texto investigativo “Especie, especificidad y pertenencia” (2013a) de la PhD. Florencia Garramuño; y consideraciones filosóficas sobre la contemporaneidad de Giorgio Agamben; el término sociológico “actividades sustitutorias” de Theodore Kaczynski; la postura de Mark Fisher con su texto Realismo capitalista (2016), son el cuerpo de antecedentes que integran este postulado crítico y permite cuestionar los valores y efectos en la experimentación narrativa, y la periferia con la que debe conciliar: la industria, la productividad y el canon literario.

Stratigraphy and structural development of the Precambrian rocks in the area north-east of Disko Bugt, West Greenland
Authors: Escher A , Burri M
Published: June 2021

The Precambrian rocks in the area north-east of Disko Bugt can be divided into a lower gneiss group and an upper supracrustal group. The lower part of the supracrustal group consists of quartzites, amphibolites and garnet-staurolite schists, while the upper part is mainly semipelitic schist. The gneisses were affected by three successive phases of deformation, while in the supracrustals only the two latest phases of folding can be recognized. Evidence is given in support of the idea that the supracrustals were deposited on a gneiss basement after the first phase of folding, the basement being later reactivated mainly during the third and last deformation. Two main tectonic compLexes can be distinguished in the area mapped: a southern complex characterized by a predominarit ENE direction of the fold axes and a northern complex in which the main fold axes are strongly curved around a central gneiss dorne. The transition zone between the southern and northern complex is marked by the presence of severaL important faults and mylonites. The gneiss dorne is flanked in its northern part by a thick granite sheet. The dorne structure appears to have been forrned by a combination of diapiric movements and the interference between two successive deformations. The gneisses and lower supracrustals recrystallized under amphibolite facies conditions, while greenschist facies conditions prevaiLed during the recrystallisation of the upper supracrustals.

Angiospermous leaves from the Lower Cretaceous Kome Formation of northern West Greenland
Authors: Pedersen K.R
Published: June 2021

The Korne Formation occurs on the north side of Nûgssuaq peninsula (70°5'N) in northern West Greenland. It extends from Ikorfat (53°5'W) eastwards to Kûk. The limnic sediments of the Korne Formation, comprising shales, coal seams and sandstones, lie on weathered Precambrian gneisses and are overlain by a younger limnic formation with more sandy sediments. The two formations are separated by a low-angle unconformity at a height of 400-500 m. The upper limnic formation has been shown by means of plant microfossils to belong to the lower part of the Upper Cretaceous. In the western part of the area the two limnic formations are overlain by marine sediments of Senonian age (Rosenkrantz, 1951).
Preliminary report on the stratigraphy of the Precambrian and Eocambrian sediments in the Jørgen Brønlund Fjord – Midsommersø area, southern Peary Land
Authors: Jepsen H.F
Published: June 2021

As a member of the 5th Danish Peary Land expedition led by Eigil Knuth, the author carried out geological field work in an area bounded by Jørgen Brønlund Fjord (82°10' N, 30-32°W), Midsommersø (82°15' , 33-36°W) and Inuiterk Sø (82°, 35°W). The same area was visited in 1966 (Jepsen, 1966) with the main object to study the intrusive rocks. In the summer of 1968 the purpose was partly to study the stratigraphy of the sediments and partly to get a better understanding of the nature of the intrusive rocks. In this note it is mainly the first problem, viz. the stratigraphy of the sediments, that will be discussed.
The Precambrian geology of the Sârdloq area, South Greenland
Authors: Windley B.F.
Published: June 2021

The geology of the Sârdloq area is divided on a chronological basis into two plutonic periods, preceded, separated and followed by periods af basic dyke intrusion. During the Ketilidian plutonic period, veined, banded and homogeneaus gneisses were formed, which were deformed in three periods af folding. The gneisses contain relicts of earlier, 1st period basic dykes. F 1 folds are relicts within the regional gneiss foliation (SI); F 2 folds forrned under syn-migmatitic conditions, giving rise to a major synform the axis af which plunges shallowly NE or SW and F 3 folds are represented by a post-migmatisation buckling af the foliation an axes trending NW–SE but with variable plunge. Ultrabasic and basic intrusions are probably related to the 2nd period basic dykes intruded in the Kuanitic cratogenic period. During the Sanerutian plutonic period the earlier gneisses were reactivated to form a new, more homogeneaus granite, in which the Kuanitic basic dykes are preserved as undisturbed relicts. The intrusion of a swarm af basic dykes under late-plutonic conditions (3rd period) was followed by the intrusion af net-veined diorite sheets, emplacement af homogeneaus microgranite bodies and tectonic emplacement af layered ultrabasic bodies. The formation af abundant dilatational pegmatites and layered aplite-pegmatites followed by a minor phase af basic dyking ended the second plutonic period. During the Gardar period NE-SW and E-W trending dolerite dykes were intruded and followed by faulting and mylonitisation. A swarm af NW-SE trending dolerite dykes was intruded in post-Gardar time.
On the magmatic evolution of the alkaline igneous province of South Greenland
Authors: Sørensen H
Published: June 2021

In 1938 E. Wegmann divided the rocks of southern Greenland into and old basement and a younger formation. The basement consists of the remains of a mountain chain for which Wegmann introduced the name the Ketilides. The younger rocks, which are separated from the Ketilidian orogeny by a long period of denudation, were grouped in the Gardar formation. The Gardar "formation" comprises supracrustal rocks, a great number of dykes and a limited number of plutonic bodies. In this article an outline of the geology and the magmatic evolution of the Gardar province will be given.

Foraminiferal biostratigraphy of the post mid-Miocene in two boreholes in the Danish North Sea
Authors: Konradi Peter B
Published: June 2021

Cutting samples from two exploration wells, Cleo-1 and Kim-1, in the Central Trough area in the northwestern part of the Danish North Sea, have been investigated for foraminiferal content in the section above the prominent mid-Miocene event. Benthonic foraminifera have been used to produce a stratigraphic subdivision by reference to the standard NSB zonation of King. The NSB 12 to NSB 17 zones (Middle Miocene to Middle Pleistocene) have been identified above the event. These zones can be related to the paleo water depth zonation. Paleoenvironrnental reconstruction shows that sediments from the subject interval from Cleo-1 were deposited in a shallower situation than equivalent deposits in Kim-1. A conspicuous hiatus is identified in Cleo-1 at the Pliocene-Pleistocene boundary.
Correlation of Miocene North Sea sequences with the Danish land area based on foraminifera
Authors: Laursen Gitte V , Kristoffersen Finn N
Published: June 2021

In the present study comparisons are made between the Miocene North Sea sequences and the Danish onshore formations based on foraminiferal biostratigraphy. Foraminiferal faunas of four onshore borings previously analyzed by Kristoffersen have been reviewed. Biozones NSB 9 - NSB 13 of the offshore sequences were all found in the Danish Miocene formations, and the obtained results promise well for a future more detailed correlation between the North Sea and the Danish land area.
Comparison of Chemical and Antioxidant Properties of Mentha Piperita L., Salvia Officinalis L., Rosmarinus Officinalis L. and Lavandula Angustifolia L.

Published: June 2021

4 different plant species belonging to the same family mint (Mentha piperita), sage (Salvia officinalis), rosemary (Rosmarinus officinalis), lavender (Lavandula angustifolia) were harvested from the Afyon region. Total antioxidant and phenolic contents were analyzed by DPPH and Folin-Ciocalteu method. The effect of extra virgin olive oils oxidation stability was tested by means of rancimat method. According to DPPH analysis results, M. piperita is the highest antioxidant capacity and the radical scavenging activity is 95.31%. The radical scavenging activities of S. officinalis, R. officinalis and L. angustifolia are respectively 91.83%, 54.28%, and 18.85%. The total phenolic content of M. piperita, S. officinalis, R. officinalis and L. angustifolia plants as gallic acid were respectively; 0.32, 0.28; 0.26 and 0.18 mg/100ml. According to the results of the study, the order of the plants did not change in terms of phenolic and antioxidant content, M. piperita has the highest values and L. angustifolia has the lowest. It was also found that the plants are effective on the oxidation stability of extra virgin olive oil and prevent oxidation in the order of large to small R. officinalis, M. piperita, S. officinalis and L. angustifolia.
Contrastive Analysis and its Implications for Bengali Learners of ESL
Authors: Ara Arjumand
Published: June 2021

Contrastive Analysis, since its introduction as a potential predictor of the influence of the learners’ first language on the second language and the resultant errors, has constantly been subject to criticism on both theoretical and empirical grounds. This once-popular approach of interpreting errors resulting from the interference from the native language met a gradual decline in acceptability as Behaviorism, the theory on which it was based, lost its credibility. Also, empirical findings pointed out its ineffectiveness as the predictor of errors. However, contrastive analysis projects have been carried out in different parts of the world to avoid errors in specific language areas, including pronunciation. This paper aims to shed light on the origin, evolution and significance of the theory, especially in designing instructional materials for the Bengali learners of English as a second language.
