Authors:   Irkutsk National Research Technical University, Yakovleva Ariadna А. , Nguyen Thuy Tr. ,   Irkutsk National Research Technical University
Published: July 2022

The sorption properties of some sands selected in the coastal zones of economically important, but at the same time ecologically oppressed territories of Vietnam are considered. The purpose of the research is to assess the absorption capacity of sands in relation to emulsified petroleum products, to identify their ecological role in typical situations of spillage of small amounts of toxic substances. It is shown that the sorption qualities of the sands depend on the location of the sands, their geochemical and granulometric heterogeneity. It turned out that according to the content of α-quartz, the sands used can be divided into two types with a clearly expressed correlation of sorption qualities with the mineral content. Quartz sands, represented by fine-grained pellets, have a high ability to retain oil films. Sands with a content of 10–11% (wt.) corundum are represented by larger and sharper-edged particles with lower bulk density and reduced absorption capacity. For each sand maximally saturated with gasoline components, the reaction to “rainy” or “sunny” weather has been investigated. For the first case, desorption with repeated washing with water has been carried out, in the second case, drying with heating and subsequent single passing of water through a layer of sand. It is shown that gasoline films are firmly held on sand particles during washing, but are easily removed when heated. With repeated washing of the underlying layers, it reaches about a quarter of the initial gasoline content in the emulsion, which is filtered through sand. When drying with heating, up to a quarter of volatile hydrocarbons are dispersed from the sands, while an insignificant amount of organic matter is found in the filtrates.

Authors:   Central Siberian Botanical Garden of the Siberian Branch of the Russian Academy of Sciences, Gerasimovich Lyudmila V.
Published: July 2022

The article presents the results of a long-term introduction of Tulipa sylvestris L. in the SB RAS Central Botanical Garden collection. Plants of the species T. sylvestris bloom abundantly and have a reproductive factor of 1–2 for the daughter bulbs. It was found that the short phase of flowering is characterized by smooth temperature changes, the most dramatic for a long period. We also established a direct dependence of the duration of the flowering period on the amount of precipitation during this period, the correlation coefficient was 0,7. Under the conditions of the CSBG, the species introduced T. sylvestris increased the parameters of the morphometric characters and decreased the indicators of an important decorative feature – the length of the petal. The number of days with of temperatures above zero and the number of sunny days have a significant impact on the quantity and parameters of vegetative organs. The amount of precipitation has a positive effect on the length of the anther, thus increasing the length of the stamen. The length of the filament and the height of the goblet also depend on the number of sunny days. The result can be considered an assessment of the success of the introduction, which for individuals of the species T. sylvestris was six points out of seven. The evaluation of resistance to introduction showed that plants of this species can be considered highly resistant in cultivation.

Authors: Sahoo Pravas Ranjan , Pashupathi M. , Patra Ritun , . Anika , . Komal , Kumar Ajay
Published: July 2022

Background: Leishmania infantum, one important intracellular parasite causes most potentially lethal diseases such as leishmaniasis i.e. Visceral leishmaniasis in dogs. Although certain chemical drugs such as pentostam, amphotericin B, miltefosine have been trailed against this disease, but all these drugs induced antibiotic resistance and toxicity in the host. Further, the trypanothione synthetase, a key enzyme of this parasite which catalyzes a reaction, maintaining thiol redox within the cell. Methods: The binding study was carried out with selected natural/synthetic phytocompounds/drugs against the modeled trypanothione synthetase though molecular docking. Result: The generated protein model with lowest discrete potential energy (DOPE) -19960.97 was found good in quality with z score of -5.19 and quality factor of 61.83% and it was found that the natural inhibitors glycyrrhetic acid (GRA) and Theaflavin (TFN) showed highest binding energies of -7.34 and -6.95 Kcal/mol. This study may be concluded that the natural inhibitors glycyrrhetic acid (GRA) and Theaflavin (TFN) would be potential regimen in treatment of canine leishmaniasis.
When treating medial patellar luxation in dogs is a block trochleoplasty superior over a wedge trochleoplasty?
Authors: Norell Candetoft Maria
Published: July 2022

PICO question

As part of the surgical correction for medial patellar luxation in dogs, which procedure results in a better outcome for the patient: block or wedge recession trochleoplasty?

 

Clinical bottom line

Category of research question

Treatment

The number and type of study designs reviewed

Three studies satisfied the inclusion criteria for answering the PICO; one cadaver study, one retrospective observational study and one clinical case series

Strength of evidence

Weak

Outcomes reported

Postoperative complications including reluxation rates.

Ex vivo: Trochlear groove depth, patella articular contact, percentage of recessed trochlear surface area, resistance to medial patella luxation

Conclusion

There is only weak evidence to support block recession trochleoplasty over wedge recession trochleoplasty as part of the surgical correction for medial patella luxation in dogs. Both procedures are associated with a good clinical outcome. There are some proposed benefits to trochlear block recession made from an ex vivo study comparing the two procedures. These include an increased patellar volume under the trochlear ridges when the stifle is extended. The articular contact and recessed trochlear surface area were also increased in the trochlear block recession group when compared to trochlear wedge recession. However, the clinical relevance of these perceived benefits remains unproven. In practice, and until prospective randomised controlled trials are carried out, veterinary surgeon preference and previous experience remain relevant factors in choosing which procedure to perform

 

How to apply this evidence in practice

The application of evidence into practice should take into account multiple factors, not limited to: individual clinical expertise, patient’s circumstances and owners’ values, country, location or clinic where you work, the individual case in front of you, the availability of therapies and resources.

Authors:   Global Studeis Education Association, Lee Eun Hwa , Kim Sang Mi
Published: July 2022

This study aims to analyze faculty perception and the need for teaching competency in developing countries through field research in the context of posit-COVID. To this end, this research developed a survey tool consisting of 34 questions in 7 areas and analyzed the collected data from 163 respondents of a national university in the Philippines. Then, the study conducted the t-test, Borich's needs, and The Locus for Focus to derive priorities and support areas for improvement needs. The research results are as follows. First, there is a significant difference between importance and performance in teaching competency, confirming the need for improvement. In particular, it showed high demand in instruction competency related to e-learning and major classes, teaching strategy related to learner participation-centered instruction, strategy on evaluation and feedback, and content knowledge. On the other hand, in terms of the competence for instructional design and analysis and organizational value practice, the difference between importance-performance level and the demand was at the lowest level. This study suggested a specific need for the development of competency for university faculty, which can serve as a basis for understanding the local needs of developing countries and exploring the way for international cooperation in higher education.
Comparative Studies on Effectiveness of Multicultural Curriculum in Korean-Swedish Teachers’ Colleges : Based on the Effect Analysis of TALIS 2018
Authors:   Global Studeis Education Association, Kim You Ah
Published: July 2022

The developed countries have made efforts to reform policies and curriculums for teacher professionalization in an multicultural or multilingual school environment through the mandatory courses of teacher training institutions. Nevertheless, Korean teachers tend to belatedly acquire the related expertise of the teaching methodology in Professional Learning Communities(PLC) rather than in teachers’ colleges.
Based on the comparison of the responses of TALIS 2018 from 2,223 Korean teachers and 6,168 Swedish teachers, who have taught in classrooms with migrant students, the effectiveness on 'Preparation for teaching elements teaching in a multicultural or multilingual setting(.057)' and 'Cultural diverse class adapt teaching to cultural diversity of students(.393)' of Swedish teachers were higher than that of Koreans. Therefore we can draw implications to nurture the related professionalism of pre-service teachers as a compulsory competency in the teachers’ college curriculum, and foster the political supports with the core strategy of the Korean National Curriculum 2022.
Cosmopolitan Approach on 'Comfort Women' Issue
Authors:   Global Studeis Education Association, Park Seong In
Published: July 2022

This study aims to analyze the ‘comfort women’ researches conducted in Korea after the 2015 Korea-Japan ‘Comfort Women’ Agreement, thinking that the Agreement served as important momentum to trigger an increase in ‘comfort women’ research in Korean society. ‘Comfort women’ researches in Korea were classified largely into the three following subject areas: First, the comfort women issue as a Korea-Japan political, diplomatic conflict. Second, the comfort women issue as a reconstruction of historical memory. Third, the comfort women issue as a social practice. Then the challenges and directions for ‘comfort women’ research were presented as follows. First, oral history about the testimony of victims should be studied. Second, ‘comfort women’ discourse, which reproduces confrontation between countries should be overcome. Third, discussion on political responsibility is required in comfort women issue. To get closer to solving ‘comfort women’ issue, further studies on political responsibility of community that tolerated structural injustice and epistemic violence as well as judicial and moral responsibility for direct violence such as war crime, cruel treatment, and violation of women’s rights are also required.
Mind the Gap: The Role of Expectations and Experience in Attracting and Retaining International Students in Korea
Authors:   Global Studeis Education Association, Potter Cuz , Oh Jihye , Kang Kyuwon
Published: July 2022

This study is intended to help Korean universities more successfully attract and retain international students by exploring the gap between cognitive, affective, and external expectations and experiences. Researchers conducted in-depth interviews with Korean studies students across a range of ethnicities and nationalities in 2021. The paper finds that the gap can be reduced in two ways. First, universities can manage the unrealistic expectations about life in Korea created through media portrayals through education and pre-enrollment exposure. Second, universities must increase their commitment to act in loco parentis for international students, who lack the tacit cultural knowledge and social networks to navigate difficulties alone.
Foreign Capital in the Women's Press in Poland in 1989-2019 – Attempted Summary Olga Dabrowska-Cendrowska
Authors: Dabrowska-Cendrowska Olga , Walkowiak Natalia
Published: July 2022

Press companies with foreign capital have been functioning on the Polish media market since 1990. In the nineties, women’s press was dominated by four media giants with German capital: Bauer Media, Burda Poland, G+J Poland, and Axel Springer Poland (‘The Big German Four’), which were later joined by Edipresse Poland and Marquard Media. In the years between 2001 and 2016, mergers and acquisitions took place which led to a concentration of the press market. As a result, in 2019 Bauer Media became the definitive leader, systematically expanding its press range in the group of multi-thematic magazines. Despite taking action, neither Edipresse Polska nor Burda International was able to compete with the media giant. The aim of this article is to analyze changes in the segment of women's multi-thematic magazines which took place between 1989 and 2019. The research used the method of system analysis, a research approach used in social sciences, which considers the notion of the system and its analysis as crucial for the understanding of social phenomena. It was assumed that the women's press published in Poland is a part of the Polish media system. It is a closed sub-segment. Considering this multi-thematic magazine group as a whole without dividing it into subsegments, it is obvious that Bauer Media was the ultimate leader – owning 13 titles i.e. 56.5% of the available magazine range. The remaining 10 magazines (43.5%) were owned by Burda International (5), Marquard Media (2), Edipresse Polska (1), Agora S.A (1) and Wydawnictwo Zwierciadło (1). In the years 2018-2019, the media giant Bauer Media extended its magazine range and gained a monopoly in the advice and gossip magazine subsegment.
Facteurs Géographiques Explicatifs des Inondations en Milieu Urbain: Cas du Bassin Versant du Cours d’eau Goley a Sinfra (Centre-Ouest Côte d’Ivoire)
Authors: Adaye Kouassi Albert , Andon N’Guessan Simon , Yao-Kouassi Quonan Christian
Published: July 2022

Cette étude géographique qui a allié le système d’Information géographique (SIG) et les enquêtes socio-culturelles de terrain révèle que les inondations urbaines du cours d’eau Goley de Sinfra ne sont liées à la forme de son bassin versant mais au mode d’occupation de cet espace. Le mode d’occupation de la surface du bassin versant est à l’origine des facteurs comme l’imperméabilisation de l’espace par l’urbanisation induisant une grande quantité d’eau ruisselée, le désordre urbanistique matérialisé par les installations des habitats hors lotissement dans les servitudes et lits du réseau hydrographique dédiés au fonctionnement hydrologique du cours d’eau. L’anthropisation anarchique des servitudes et lits urbains du Goley, l’absence d’aménagements de ces derniers contre les inondations, la présence de divers aménagements dont des voiries aux ponts obstrués par la matière plastique formant des digues de barrage et les acteurs gestionnaires de cet espace sont les facteurs explicatifs des inondations urbaines du Goley à Sinfra. La sacralisation d’une partie du tronçon du réseau hydrographique urbain du Goley montre la mainmise des populations sur cet espace et heurte d’avance tout projet d’aménagement du cours d’eau Goley contre les inondations dans le bassin versant urbain.

Published: July 2022

Leafy vegetables are an important source of essential components of rural people diet in tropical Africa. This study aimed to characterize the free amino acids of five leafy vegetables consumed in Western Côte d 'Ivoire. The leaves of Abelmoschus esculentus, Celosia argentea, Ipomea batatas, Manihot esculenta, and Myrianthus arboreus were collected at maturity from cultivated farmlands located at Dabou (Abidjan District). These five leaves were washed and oven-dried at 60 °C for 3 days. The dried leaves were then ground and the powdered samples of each leaf were analysis for its amino acid contents using HPLC. The results showed that the amino acid contents of each leaf vegetable were significantly different (p ˂ 0.05). The proline which is a non-essential amino acid was found in all the leaves with contents varying from 563.6 ± 1.08 to 1562.9 ± 1.88 mg/100 g. For essential amino acids, leucine contents of the leaves ranged from 175.9 ± 0.56 to 9685.9 ± 5.14 mg/100 g. Among the five leafy vegetable, lysine was quantified in leaves of C. argentea (266.7 ± 0.89 mg/100 g), I. batatas (7225.9 ± 2.56 mg/100 g) and M. arboreus (182.4 ± 0.66 mg/100 g). Tryptophan could not be detected in C. argentea, M. esculenta and M. arboreus. M. esculenta recorded the highest content of valine (1639.1 ± 1.39 mg / 100 g) compared to C. argentea (1069.4 ± 1.2 mg / 100g). Methionine is the only sulfur amino acid detected in C. argentea (165.1 ± 0.61 mg / 100g). These results show that leafy vegetables consumed in Western Côte d'Ivoire are an important source of amino acids. Therefore, they can contribute to improving the nutritional quality of food and ensure food security.

As the global population moves towards 10 billion people, record high temperatures are being set on an annual basis, while agricultural soils and water resources are experiencing serious attrition. Clearly the challenge of food security is ever more urgent. Increasing genetic gains of staple foods is a key part of the solution, since seed-embedded technologies are readily adopted by farmers. Improved breeding technologies facilitate the identification of complementary parents for hybridization and the selection of improved progeny. This chapter outlines a historical basis for plant selection and examines the areas in which sensor technology has evolved from our eyes to the application of proximal and remote sensing. The use of none-invasive methods are presented that can aid with selection of crop characteristics critical for improving yield potential, such as photosynthesis and partitioning-related traits, as well as the detection of traits that help protect yield, related to disease and lodging resistance.

Published: July 2022

Plant phenotyping technologies have been developing rapidly in the last decades. Among various phenotyping technologies, optical sensing such as RGB, multi-spectral and hyperspectral imaging have become popular and widely applied in different applications. In this chapter, these optical sensors are generally introduced first with a review of recently published literature in this area. With the objective of helping users to wisely select the right sensor for the right phenotyping application, this chapter also focuses on the comparison of advantages and disadvantages between the different sensor options. Particularly, the major bottleneck challenges around the optical sensors are discussed, including the distribution of stresses/nutrients/color across the canopy, the complexity of the canopy’s 3D structure, plant’s diurnal changes, and the impacts from the changing environmental conditions. Some potential solutions to these challenges are provided in the case studies, and the future technology development trend is also discussed.

Published: July 2022

The revolution in digital phenotyping combined with the new layers of omics and envirotyping tools offers great promise to improve selection and accelerate genetic gains for crop improvement. This chapter examines the latest methods involving digital phenotyping tools to predict complex traits in cereals crops. The chapter has two parts. In the first part, entitled “Digital phenotyping as a tool to support breeding programs”, the secondary phenotypes measured by high-throughput plant phenotyping that are potentially useful for breeding are reviewed. In the second part, “Implementing complex G2P models in breeding programs”, the integration of data from digital phenotyping into genotype to phenotype (G2P) models to improve the prediction of complex traits using genomic information is discussed. The current status of statistical models to incorporate secondary traits in univariate and multivariate models, as well as how to better handle longitudinal (for example light interception, biomass accumulation, canopy height) traits, is reviewed.

Recent models predict population to peak in 2064 at around 9.7 billion, and then will likely decline to about 8.8 billion by 2100. This requires to increase crop production significantly. Precise phenotyping of the large breeding populations under diverse environments is required to harness the full potential of modern breeding techniques, and has become the new bottleneck in breeding programs. Development and application of advanced cost and time efficient phenotyping techniques on a large scale will have a major impact on achievable genetic gain in general and grain yield in specific. Traditional phenotyping techniques applied are generally time consuming and labor intense. This puts an upper limit on the size of the screening population. As such, the role of high-throughput phenotyping (HTP) techniques that allow fast and accurate phenotyping of large breeding populations in the field cannot be understated in its role for achieving higher grain yields.

Telah dilakukan penelitian tentang distribusi beberapa parameter metereologi saat terjadi kebakaran hutan dan lahan di kabupaten Muaro Jambi. Parameter metereologi yang digunakan adalah suhu maksimum dan kelembaban rata-rata harian kabupaten Muaro Jambi sepanjang tahun 2019. Data tersebut diolah menggunakan Microsoft Excel dan dipetakan menggunakan perangkat lunak Surfer 11 untuk melihat distribusi suhu maksimum dan kelembaban rata-rata secara temporal. Surfer 11 secara default menggunakan metode Kriging dalam proses gridding data. Selain itu digunakan juga data jumlah titik panas (hotspot) provinsi Jambi tahun 2019 berdasarkan data satelit AQUA/TERRA (LAPAN) untuk melihat distribusi titik panas berdasarkan bulan dan kabupaten. Hasil yang diperoleh yaitu suhu maksimum yang terbesar berada pada rentang 33.5 °C  – 36 °C dan kelembaban rata-rata terkecil berkisar 62% – 72%, terjadi pada bulan September 2019. Sedangkan dari pengolahan data hotspot, jumlah titik panas terbanyak terdapat di kabupaten Muaro Jambi dan terjadi pada bulan September 2019. Hal ini menunjukkan bahwa kebakaran hutan dan lahan akan cenderung mudah terjadi pada kondisi cuaca suhu tinggi dan kelembaban rendah

Potassium feldspar (Kfeldspar), along with albite, is one of the leading minerals of alkaline ore (rare-metal-rare-earth) fenites of the Kosyu ore cluster of the Middle Timan. In the studied potassium feldspars, the data on an insignificant admixture of sodium oxide (0.19-0.38 wt.%) according to the results of microprobe analysis are confirmed by X-ray diffraction studies, which also indicate a minimal structural admixture of the albite component in KF. As determined by X-ray diffraction, potassium feldspar of ore fenites is a microcline. Several of its varieties have been established: the maximum microcline (Oktyabrskoe ore field), the low microcline (Novobobrovskoe and Verkhne-Shchugorskoe ore fields), and the intermediate microcline (Nizhne-Mezenskoe ore field). Kfeldspars of fenites were formed under the action of alkaline solutions on quartzite sandstones in a fairly wide temperature range from 375° to 510°C. The lowest temperature (375°C) is the most ordered maximum microclines of the Oktyabrskoe ore field. For low microclines, temperatures of 420°C and 455°C have been determined for the Novobo¬brovskoe and Verkhne-Shchugorskoe fields, respectively. The least ordered intermediate microcline of the Nizhne-Mezenskoe ore field was formed in the range of 485-510°C.
