Published: December 2021

Glyphosate-resistant sourgrass is difficult to control, particularly when perennial, and strategies that improve the control efficiency against this grass and preserve the useful life of graminicides are warranted. Therefore, the present study aimed to answer the following questions: (i) Does fractionating the doses of ACCase inhibitors improve the control of perennial sourgrass? (ii) Does alternating the chemical groups cyclohexanediones (DIMs) and aryloxyphenoxypropanoates (FOPs) improve the control of perennial sourgrass, and does the order of their application affect sourgrass control efficiency? (iii) Does the addition of glyphosate to ACCase inhibitors improve to the control of perennial sourgrass resistant to 5-enol-pyruvyl-shiquime-3-phosphate synthase inhibitors? Two field experiments (I and II) were performed in 2018 and repeated in 2019. In experiment I, the treatments included a single or fractional application clethodim + quizalofop-P-ethyl (216 + 108 g a.i. ha-1), clethodim (216 g a.i. ha-1), and quizalofop-P-tefuryl (108 g a.i. ha-1), applied in the order of clethodim followed by quizalofop-P-tefuryl and vice versa, as well as a control treatment. In experiment II, the treatments included a single or fractional application of clethodim + quizalofop-P-ethyl (216 + 108 g a.i. ha-1) and clethodim (108 g a.i. ha-1), isolated or associated with glyphosate, as well as a control treatment. In both experiments, the interval between the fractional applications was 7 days. Percentage of control, number of tillers per plant, and height of sourgrass plants were determined. Compared with the unfractionated application, the fractionation of clethodim + quizalofop-P-ethyl and clethodim increased control by respectively 20-24 and 25-30%. Fractionated clethodim has greater
Acute Dislocations of the Sternoclavicular Joint: A Review Article

Published: December 2021

Acute dislocations of the sternoclavicular joint are uncommon injuries, and it is difficult for physicians to develop expertise in treating these injuries because of their infrequent nature. No level I evidence currently exists for these injuries, but several retrospective studies and surgical techniques have been described. For acute injuries, current recommendations include early treatment with closed reduction. If unable to attain or maintain reduction after a closed attempt, open management should be considered. Previous reviews have outlined relevant anatomy, physical examination findings, and imaging for these injuries. This article aims to review updated information from the past decade regarding techniques for reduction, outcomes, and complications related to the injury and surgical management.
Influence of Oligonucleotide-Stopper on Size and Thermal Stability of Concatemer DNA Compexes
Authors: Filippov Nikolay , Lomzov Aleksandr , Pyshnyi Dmitriy
Published: December 2021

Multicomponent polymeric associates based on nucleic acids are well used in drug and gene delivery into cells, in DNA fragments manipulations, in amplifying of the molecular hybridization signal, etc. Nevertheless, the formation of these systems is not well studied. In this paper, influence of a component that terminates concatemer elongation on a length and thermal stability of the multicomponent complex was studied. We have shown that addition of a oligonucleotide-stopper to the polymeric complex consisting of two oligonucleotide species decreases the length of concatemer complexes proportionally to the stopper concentration. Effect of the stopper on melting temperature was shown to be concentration dependent. We have proposed a thermodynamic model, which allows one to predict the thermal stability and the length distribution of the concatemeric complex consisting of two types of oligonucleotides in the presence of the stopper. We have also determined the length of polymeric complexes, which makes the maximum contribution to the intensity of the analyzed signal

Published: December 2021

The results of the application of PIV technique to study the turbulent structure of cavitating flows around a cascade of NACA0015 series hydrofoils are presented. Based on instantaneous velocity fields measured, spatial distributions of the mean velocity were calculated as well as the second-order statistical moments of liquid velocity fluctuations. Quantitative characteristics of the flows around the cascade and a solitary profile were demonstrated to be considerably different due mainly to discrepancies in distributions of the mean pressure and mutual impact of cavitation clouds

Published: December 2021

For the formation of a narrow atomic diagnostic beam the providing of small angular divergence is fundamentally important issue. When using a slit geometry angular divergence of the beam in the direction along the slit is mainly determined by ion temperature in the plasma source. As a result of the applying the multislit ion optics to the injector RUDI the total beam current (in ions) is increased from 2 to 3 A, the angular divergence of the beam in the direction along the slit is reduced to 0.35º

What’s in a Name? Questions for a New Monument
Authors: Troensegaard Margrethe
Published: December 2021

What is the contemporary condition of the monument? In relation to the current issue’s discussion of immersive and discursive exhibition practices, this essay places itself at a slight remove; rather than to analyse and evaluate specific curatorial strategies it seeks to raise questions of relevance to such practices and begins by moving the discourse out of the museum and into the public space. The point of interrogation here is the monument, a form with a particular capacity to tease and expose the triad we find at the core of any curatorial discourse: the relation between institution, artwork and audience. Following an introductory reflection on how to describe and define a ‘monument’, a term so broadly used it all but loses its value, the text proceeds to examine three cases, Monument de la Renaissance Africaine, Dakar (2010), Danh Vo’s WE THE PEOPLE (DETAIL), various locations (2010-13), and Thomas Hirschhorn’s Gramsci Monument, New York (2013). The sequencing of these geographically and culturally diverse works makes way for an interrogatory piece of writing that addresses the question of permanence versus temporariness of the artwork as exhibition (and the exhibition as artwork), and that of the political agency of the artistic form. Probing the social agency of the monument, the text draws lines between the symbolising capacity once held by modern sculpture and the oscillation between immersion and discursiveness as two complimentary modes of communication. The discursive content or function of the monument (i.e. what it commemorates) is activated through the viewer’s personal, immersive encounter with its form, a form that potentially places its viewer as a participant to the construction of its message rather than as a mere receiver.

Authors: Zankova Bisera
Published: December 2021

The article discusses the democratic changes in the Bulgarian society and the new regulatory system from the perspective of media and legal cultures. The article analyzes legal phenomena as such, as well as the social environment in which they have emerged and developed during the years of democratic transition. Law is a social regulator and has to serve the public interest. In Bulgaria, however, it has always been subject to the political will of the majorities and could not fulfill its function to provide the necessary basis for the establishment of democratic regulatory culture, management culture and culture of independence within the media.

El IESALC/UNESCO tiene el agrado de presentar un nuevo número de la revista Educación Superior y Sociedad (EES). Se da esta edición en un contexto en el que la pandemia de Covid-19, lejos de haber sido superada, ha costado ya más de cinco millones de vidas en el mundo, sin que todavía se puedan precisar plenamente sus efectos en la sociedad y en los sistemas educativos. Al tiempo que en todo el continente persisten las restricciones de movilidad y siguen en lontananza las perspectivas de retorno masivo a la presencialidad, las instituciones de educación superior han tenido que reinventarse y asumir, además, un importante rol en la mitigación de los efectos sociales de la pandemia. A su vez, han buscado modificarse, al punto de que la indagación sobre los efectos de la enfermedad y sobre la llamada “nueva normalidad” constituyen un tema central de nuestras reflexiones. A todo ello le dedicamos una convocatoria especial como dossier de este número. Consideramos que este número de ESS será sin duda una importante contribución al ineludible debate sobre la pandemia, la postpandemia y el futuro de la universidad y la educación en general, y contribuirá con seguridad a enriquecer los planteamientos de los colegas investigadores y de las autoridades universitarias y educativas de la región, pero también fuera de ella.

THE EFFECT OF OLIVE OIL SUPPLEMENTATION IN ADOLESENCE
Authors: Andi Faradilah  , Darmawansyih  , Darwis Burhanuddin
Published: December 2021

Background

Olive oil has been shown to reduce the risk of atherosclerosis through its anti-inflammatory, antioxidant, and vasodilator effects. Olive oil contains polyphenols against the reaction of Reactive Oxygen Species. In Al Quran, Surah Al Mu'minin verse 20, it is stated that olive oil can be helpful as an appetite enhancer. This effect can occur through the role of MUFA as olive oil composition in the mechanism of the gut-brain axis where the hormone ghrelin produced by the intestine will enter the brain to induce appetite. The Adolescent period is a significant concern because this is a period of growth and development that requires adequate nutritional intake. The sustainability of appetite in adolescents is a good sign for fulfilling nutritional needs to support optimal growth and development.

Objective

This study aims to examine the effect of olive oil supplementation on the appetite score in adolescents.

Methods

The study was conducted at the Tahfizh Al Quran Zam-Zam Islamic Boarding School with 30 subjects divided into two groups: the treatment group (n = 15) and the control group (n = 15) who met the inclusion criteria. The study revealed that no difference was showed in the proportion of appetite scores in the two groups.

Conclusion

There is no difference of the appetite scores on the administration of olive oil in adolescents.

Key words: Olive oil, food intake, appetite score, adolescents.

The following works have been implemented Kalamkas field: a complex of geological, geophysical and field exploration; correlation schemes to track the lithology of the formation; clarifying structural maps and engineering maps; justifying activities to select one or more wells for horizontal drilling; hydrodynamic calculations and estimating their flow rate.
Deep oil. Offshore deposits of the Gulf of Mexico
Authors: Iskaziev K. O. , Syngaevsky P. E. , Khafizov S. F.
Published: December 2021

This article continues a series of reviews of the worlds oil and gas basins, where active exploration and development of hydrocarbon deposits in superdeep (6 km +) horizons are taking place, as probable analogues of projects in the Caspian megabasin, primarily the Eurasia project. In this regard the Gulf of Mexico is of great interest, since this region is very well studies over such a long history of its development and thus makes it possible to analyze a huge amount of data collected during this time.

The Gulf of Mexico includes the deep-water, offshore and coastal parts of three countries the United States, Mexico and Cuba, and is one of the most important oil and gas provinces in the world. Its deposits are represented by various complexes from the Middle Jurassic to modern sediments, with a total thickness of 14,000 m and more. Exploration for hydrocarbons has been going on here for almost 100 years. During this time, various new technologies have been developed and successfully applied, such as forecasting abnormally high reservoir pressure, cyclostratigraphy and seismic facies analysis, characterization of low-resistivity productive reservoirs and the search for ultra-deep hydrocarbon deposits.

Of all the variety of objects developed in the Gulf, in the context of the study of deep deposits, the main interest and possible associations with the Caspian megabasin are the deposits of the Norflet Formation of the Upper Jurassic, which are discussed in the main part of this article. Of course, we are not talking about a direct comparison; in particular, the aeolian origin of part of the section makes this object significantly different. Nevertheless, according to the authors, studying it, as well as understanding how a successful project for its development is being implemented right before our eyes, can provide a lot of important information for working in the deep horizons of the Caspian region.

The article is divided into two parts. The first examines the geological history of the formation of the Gulf of Mexico Basin, the features of the deep-lying productive complex of the Norflet Formation. The second part provides information about the history of exploration of the Norflet productive complex, characteristics of the main discoveries, as well as the prospects for discoveries of new superdeep deposits in the Norflet Formation within the Gulf of Mexico (sectors of the United States and Mexico). Analysis of the history of the development of this complex by the global player Shell, is very important, as one of the scenarios for the development of deep horizons in other oil and gas basins, incl. Caspian. International Oil Companies are able to mobilize the necessary resources and technology to effectively address this challenge.
The importance of selecting the correct mapping methods for fractured carvernous reservoirs in complex carbonate sediments
Authors: Mankenov K. K.
Published: December 2021

In this article, the author attempted to draw attention to finding and identifying structurally complex reservoir zones in mature carbonate fields, where fractures are of paramount importance. The development of fractured reservoirs of carbonate fields is one of the main areas for boosting production, and most of the significant discoveries took place in described areas. According to the latest calculations, more than 60% of oil reserves and 30% of gas are concentrated in carbonate sediments.

Adapting new technologies and transforming the prospecting paradigm makes it achievable to identify fundamentally new areas of research and give an entirely new level of understanding of the geological structure and reservoir properties of mature fields with structurally complex reservoirs. The probability that many of them contain prospects is very high, prospecting and developing these areas that can give them a second life and ensure profitable production.
Durability of cement stones in injection wells
Authors: Agzamov F. A.
Published: December 2021

Cement stone is the weakest component of the wells, it is easily destroyed when working inside the casing and is vulnerable to the action of most formation fluids. In injection wells, under the action of water injected into the reservoir, intensive leaching of the cement stone occurs, which leads to its complete degradation after several years of well operation. The consequence of this is the injection of fluid into other formations and increased corrosion of the casings. Analysis of the field experience of injection wells showed that inter-reservoir crossflows result in cement stone complete collapse in 4-6 years, while in production wells it retained its properties after 20 years.

Theoretical consideration of the leaching corrosion process made it possible to determine the main directions of reducing the corrosion rate, aimed at improving the structural characteristics of cement stone. Among these, a decrease in the initial water-content and optimization of the porous structure should be optimized.

Analysis of the loads acting on the cement sheath in wells showed that during perforation, hydraulic fracturing and well drilling for deepening, the stresses arising in the cement stone exceed its strength characteristics. Therefore, it is advisable to use reinforced and self-healing cements to minimize these negative effects.
Controlled deep perforation by radial drilling of channels with the "Perfobur" technical system to intensify the reservoir inflow
Authors: Bashirov A. I. , Galas I. R. , Лягов I. A. , Nazyrov M. F.
Published: December 2021

The paper presents a technology for controlled deep penetrating perforation using the Perfobur technical system to intensify inflow by drilling radial channels 69 mm in diameter, up to 25 metres in length. This technology was first applied to a carbonate reservoir in the Bashkirian tier, characterised by high heterogeneity and close proximity of bedrock water.

An adjacent well, close to the acid fracture well, with identical reservoir properties, was selected. Well "A" was acid fractured and well "B" was drilled using Perfobur technology with two directional channels, each 14 metres in length. In well "B", after drilling the channels, hydrochloric acid solution was injected through a special hydromonitor nozzle at two points. A total of 48 m3 of acid was injected into the "B" well.

Comparing the results of well "B" with the well where the hydrofracturing was performed allow speaking about high efficiency of the controlled radial drilling technology. The ability to predict the channel trajectory, knowledge of its actual trajectory in combination with acid treatment of the reservoir using hydromonitor nozzle at a considerable distance from the reservoir allows achieving a significant increase in oil flow rate with lower water cut of the produced oil.

Assessment of nutrition knowledge during lactation among postpartum women
Authors: Kalita-Kurzyńska Kinga , Mołas Aleksandra , Kozak Karolina , Dulęba Marta , Kiersnowska Iwona
Published: December 2021

Background: Breastfeeding is the most appropriate form of nutrition for newborns and infants. During lactation, milk production is an important function of a new mother’s body. The lack of a healthy, balanced diet carries a high risk of macro- and micronutrient deficiencies in postpartum women.
Aim of the study: The aim of the study was to explore the nutrition knowledge of postpartum mothers during lactation, based on current guidelines.
Material and methods: The study involved 103 postpartum mothers who stayed in the maternity and neonatal ward in a secondary care hospital from April 2019 to January 2020. The diagnostic survey method was used as the research tool, which included an original questionnaire. Participation in the study was voluntary and anonymous. Results were analyzed using Microsoft Excel descriptive statistics. The analysis of Spearman’s R correlation between the variables was performed in the Statistica 13.1 program. Statistical significance was taken at p < 0.05.
Results: The average score among respondents was 4.82/10 points. Most study participants (77%, n = 79) considered breastfeeding women to have greater energy and nutritional requirements. More than half of the study participants (59%, n = 61) declared that some food products should be eliminated from the diet, namely strawberries, citrus fruit and chocolate.
Conclusions: Women’s knowledge about nutrition during lactation is insufficient. There is a need to intensify education in this area by medical professionals including midwives.

For many years it has been well known that tar was an available commodity in the Norwegian Iron Age, but until recently no production site or installation for such production was known. In this paper two recently discovered tar production sites, in south-eastern and mid-Norway respectively, are presented and discussed. Both are clay-lined funnel-shaped pits that are dug into the ground with an upper part where the wood was stacked and lit, and a lower part where the tar was collected in a container. The Norwegian tar production pits are similar to contemporary Swedish ones found in large numbers in mid-Sweden. The type is also known from the eastern part of Central Europe where they came into use a few centuries later than in Scandinavia.
Pilegrimsspor fra Tynset: En detektorfunnet blymedaljong med kristne motiver
Authors: Simonsen Margrete Figenschou , Kjesrud Karoline
Published: December 2021

In 2016, a metal detectorist found a circular lead medallion with iconography on both sides in Tynset in the Østerdalen valley. This article studies the medallion’s shape, function and symbolical content. The object is interpreted as a pendant comparable with pilgrim badges from the late medieval period. The motifs are identified as Christian, representing the apocalyptical Mary with Christ on one side, and a passion and resurrection scene on the other. In this article, the medallion is compared to Norwegian and other European pilgrim badges and amulets with the same motifs, suggesting its origin most likely to be Aachen in Germany. Aachen was one of the most visited holy places for pilgrimage in Europe. The motifs can be connected to the Marian cathedral in Aachen, at the same time as expressing religious content regularly transmitted in the late medieval church. By comparing the motifs with Old Norse texts and images, the article demonstrates how the amulet’s religious messages potentially could influence the bearer – possibly a Norwegian pilgrim.

In the Golden Isles of Georgia, the Gullah art of braiding sweetgrass into baskets can be traced back over 400 years to its West African roots. This skill is passed on from generation to generation, preserving the oral history, sovereignty, and culture of the Gullah people. Local and indigenous coastal communities, like the Gullah-Geechee, have a deep connection with their natural environment as they depend on forests, fisheries, and wildlife resources for their livelihood and culture. These frontline communities are also facing a complex web of challenges that include rising sea levels, coastal erosion, saltwater intrusion, encroaching development and increasing property taxes, and loss of fisheries and other coastal livelihoods. As communities develop strategies to address these complex challenges, they need access to place-based research and education that is unique to their people, culture, and ecology.
Co-Creating Learning in Oceanography
Authors:   University of Bergen, Glessmer Mirjam , Daae Kjersti
Published: December 2021

Using active methods to involve students in teaching improves student learning (Deslauriers et al., 2011, 2019; Freeman et al., 2014). For many teachers, breaking up a lecture with multiple choice questions and peer instruction has become an integral part of their teaching (Stains et al., 2018). We suggest involving students in creating the framework in which they learn together with their teachers (Cook-Sather et al., 2014; Bovill, 2020). Teaching then becomes more inclusive, and students try out new roles that support them in becoming more independent, secure, and responsible (Bovill, 2020). Co-creation gives students the chance to feel competent both in class and in their lives, as formative interactions make taught content more relevant to them (Boston, 2002; Black and William, 2009). Experiencing competency, autonomy, and relatedness is what makes intrinsic motivation possible (Deci and Ryan, 2000). It is thus not surprising that co-creation enhances learning and leads to more positive interactions between students and teachers (Bovill, 2020; Kaur and Noman, 2020).

Ndomondo-Sigonda et al. (2017) observed that there is scarcity of information on human resources (person-nel devoted to regulation of medicines) in the domain of medicines regulation in the sub-Saharan Africa (SSA). The published information on medicines regulation by the National Medicines Regulatory Authorities (NMRAs) in the Economic Community of West African States (ECOWAS) region are no longer current and consistent with the current realities in the NMRAs. In order to reveal this occurrence, show the trends that exist over the years and make appropriate recommendations, data were collected and compared from 2005, 2010 and 2017 research reports on seven regulatory features of the fifteen Members States of ECOWAS. The re-sults show that there was missing information per regulatory feature and country. There was also an overall increasing trend in the number of NMRAs in the region that showed progress with respect to the measured regulatory features - Autonomy (Authority and Legal form), Marketing Authorization), GMP inspection, Quality Control, Quality Management System, Information Management System and Harmonization and International cooperation. People of Africa have a valuable story to tell as it relates to medicines regulation. This report is written by a West African from the perspective of a West African involved in the study and practice of medi-cines regulation by the NMRAs in the ECOWAS.
Geo-economics and the Hub and Spokes system: the Japanese case
Authors: Vega Ricardo
Published: December 2021

This paper examines the reasons why Japan has been building a foreign trade policy based on a hub-and-spokes system. It will be argued that trade efficiency and exports promotion are assumptions that need a broader reconsideration through a geo-economics approach. What defines Japan’s pursuit of several bilateral trade agreements is assuring its relative economic hegemony whilst changes in the world balance of power are taking place. As Japan faces an uncertain and unforeseeable future, it needs to strengthen its trade policy to guarantee access to international markets. Japan’s trade policy goes beyond the efficiency scope and it entails a geo-economics elucidation.

Padrões espaço-temporais trazem conhecimento de sequências de eventos, local e momento em que ocorrem. Encontrar tais padrões é uma tarefa complexa e de grande valor para diferentes domínios. No entanto, nem todos os padrões são frequentes em todo um conjunto de dados, ocorrendo com frequência em espaço e tempo restritos. Este trabalho formaliza a Mineração de Sequências Restritas no Espaço e no Tempo, sem o uso de limiares de restrição para tempo e espaço. Isso permite que diferentes tamanhos de sequências, intervalos de tempo e espaço tridimensional apresentem tais padrões. Traz também validação com uma implementação testada sobre um conjunto de dados sísmico real. Tendo como resultado uma análise de sensibilidade e avaliação do uso de recursos que indicam a validade e viabilidade da solução.

The goal is to compare their topics of interest and evolution over the COVID-19 pandemic period by analyzing Jupyter Notebook and Python projects from a year before and during the pandemic. We employ a state-of-art algorithm to find topics based on the repositories descriptions, and compare the performance of tuning its hyperparameters for better accuracy.
Managing Sparse Spatio-Temporal Data in SAVIME: an Evaluation of the Ph-tree Index
Authors: Herrera Stiw , Silva Larissa Miguez da , Reis Paulo Ricardo , Silva Anderson , Porto Fabio
Published: December 2021

Scientific data is mainly multidimensional in its nature, presenting interesting opportunities for optimizations when managed by array databases. However, in scenarios where data is sparse, an efficient implementation is still required. In this paper, we investigate the adoption of the Ph-tree as an in-memory indexing structure for sparse data. We compare the performance in data ingestion and in both range and punctual queries, using SAVIME as the multidimensional array DBMS. Our experiments, using a real weather dataset, highlights the challenges involving providing a fast data ingestion, as proposed by SAVIME, and at the same time efficiently answering multidimensional queries on sparse data.

Extended Pre-Processing Pipeline For Text Classification: On the Role of Meta-Features, Sparsification and Selective Sampling
Authors: Cunha Washington , Rocha Leonardo , Gonçalves Marcos A.
Published: December 2021

Pipelines for Text Classification are sequences of tasks needed to be performed to classify documents. The pre-processing phase of these pipelines involves different ways of manipulating documents for the learning phase. This Master Thesis introduces three new steps into the traditional pre-processing phase: 1) Meta-Features Generation; 2) Sparsification; and 3) Selective Sampling. Our experimental results, based on more than 5.600 measurements, show that our proposal can achieve significant gains in effectiveness when compared to the traditional TF-IDF representation (up to 52%) and word embeddings (up to 46%), at a much lower cost (9.7x faster). Our Master Thesis also includes a thorough and rigorous evaluation of the trade-offs between cost and effectiveness associated with the introduction of these new steps into the pipeline, as well as a comprehensive comparative experimental evaluation of many alternatives. This thesis falls under the topics of (i) Document Management and Classification, (ii) Information Retrieval Models and Techniques, (iii) and Text Database of the SBBD Call for Papers.
User Steering Support in Large-scale Workflows
Authors: Souza Renan , Mattoso Marta , Valduriez Patrick
Published: December 2021

Large-scale workflows that execute on High-Performance Computing machines need to be dynamically steered by users. This means that users analyze big data files, assess key performance indicators, fine-tune parameters, and evaluate the tuning impacts while the workflows generate multiple files, which is challenging. If one does not keep track of such interactions (called user steering actions), it may be impossible to understand the consequences of steering actions and to reproduce the results. This thesis proposes a generic approach to enable tracking user steering actions by characterizing, capturing, relating, and analyzing them by leveraging provenance data management concepts. Experiments with real users show that the approach enabled the understanding of the impact of steering actions while incurring negligible overhead.
