Neither Technicians nor Technocrats: pluralism and democratic accountability in schools
Authors: Kelly Peter
Published: September 2020

Whether the relationship between policymaking and science has been affected by the coronavirus pandemic remains unclear. The success scientists have enjoyed in dealing with the virus and hopes they will develop a vaccine may increase the status of some experts whilst damaging populist
anti-science sentiment. Some may call for increased technocracy, where experts run the state. However, the opposite is also possible, as science is exposed as a combination of evidence and opinion, and tarnished by its association with untrustworthy politicians using it to justify their policies.
This, then, would seem like a good time to clarify the scope and limitations of science in developing public policy. The author's interest is in education, where managerial practices dominate whilst a new science modelled on evidence-informed medicine has emerged, which promises to find out
'what works' to raise student attainment. But evidence has limitations and politics often influences its selection and interpretation – concerns that could undermine public confidence and play into populist hands. Instead, decision-makers should acknowledge these difficulties, take a
more pluralist stance to research-informed practice, and act transparently to allow public scrutiny and support democratic accountability.

PURPOSE: The purpose of this study was to induce sufficient fatigue through the Jiu-Jitsu game imitation exhaustion treatment that reflects the characteristics of Jiu-Jitsu competition, and then fatigue-related indicators according to the self-healing treatment method performed during the break between each treatment and to examine the effect on Jiu-Jitsu exercise performance.METHODS: Eight Jiu-Jitsu athletes (28.3±3.62 years, 24.6±2.5 kg/m2, 14.6±4.6% fat) participated in the study, and their exercise performance, RPE, lactate, CK, and CRP were measured after inducing exhaustion using the Jiu-Jitsu Fight Gone Bad (JFGB; 4 rounds×6 minutes JFGB, 12 minutes of recovery between rounds) test. These variables analyzed using two-way ANOVA with bonferroni’s correction.RESULTS: All the exercise performance, lactate level, and RPE showed only the difference over time according to JFGB treatment, and there was no significant difference according to recovery methods (passive recovery; PR, active recovery; AR, cryotherapy; CTR, oxygen inhalation; OIR). On the other hand, in the case of CRP, there was no significant difference in interaction effect, group, and time main effects. CK showed a significant difference only before and after JFGB treatment, but similarly, there was no difference according to recovery methods.CONCLUSIONS: Regardless of the recovery method, all variables showed a significant difference only over time according to the JFGB test, and the AR, CTR, and OIR methods were similar to the PR. However, it was observed that in the case of CK, immediately after the JFGB test, it increased significantly regardless of recovery measures.

Published: September 2020

The authors examined the efficiency of plasma-pulse-driven dielectric barrier discharge oxidation of a solution of methylene blue (C16H18ClN2S) and wastewater from dye-producing plants, in which the main component is 2,4-dinitrotoluene (CH3C4H3(NO2)2), as well as models of the organic component of wastewater of nuclear power plants, the main constituent of which is a phosphate (PO4 3−)-based detergent with a 26.8% surfactant content. Water films with a thickness of 0.1 mm were processed with a discharge voltage equal to 3 × 1011 V/s. The energy efficiency of water treatment was studied against the specific energy input, the frequency of the repetition of the discharge pulses and the parameters of the fluid and gas going through the discharge chamber. The highest energy output was reached at an air velocity in the discharge chamber of ∼1 cm/s, which provides a concentration of ozone (O3) of ∼1.5 mg/l. The highest energy output, the processing of 87 g of wastewater with 1 kWh, was obtained by treating an aqueous solution of methylene blue with an initial concentration of 50 mg/l at 65% decomposition. An energy consumption of 10 J is the most efficient value for treatment of the tested 10 ml wastewater samples.
The Replacement of Seashells with Calcite in White Ceramic Glaze Preparation
Authors: KOROGLU Levent , PEKŞEN Ceren
Published: September 2020

In this study, the effect of seashell utilization as a replacement for calcite on the surface features and optical properties of white ceramic glazes was investigated. As received seashells collected from Black Sea beaches of Samsun, Turkey and purified seashells at 700°C for 1 h were used as calcite replacement by 15 wt.%. Seashell powders were incorporated to white glaze compositions which are applied on the surface of different fired clay bodies such as red clay, chamotte, white and porcelain by dipping technique. Next, the glazed green bodies were sintered at 1100ºC for 8 h. Following to TG-DTA, heating microscope, XRD and optical analysis, the obtained results exhibited that as received seashell powder (SP-1) was composed of calcite (CaCO3), whereas purified seashell powder (SP-2) comprised aragonite (CaCO3) and calcium oxide (CaO). The iron (hematite) content in red clay and the impurities in seashells composition caused specks and crawlings on the surface of glazed red clay bodies and of some glazes containing seashell, respectively. In generally, the higher CaO content in SP-2 enhanced gloss (60°) values, and whiteness values of most glazed surfaces were closed to each other. The color of chamotte bodies increased redness-greenness values. The variations in optical parameters were mainly associated with the difference in body compositions. SP-1 contained glaze, applied on porcelain body, was selected as optimal because that had 33 gloss value, high whiteness (87) and no surface defect. Therefore, the utilization of as received seashells by 15 wt.% as calcite replacement allows eco-friendly and cost-effective production of white ceramic glazes without any additional heat treatment.

Authors: ÇETİNKAYA Süleyman , DEMİR Ali
Published: September 2020

In this research, we discuss the construction of analytic solution of non-homogenous initial boundary value problem including PDEs of fractional order. Since non-homogenous initial boundary value problem involves Caputo fractional order derivative, it has classical initial and boundary conditions. By means of separation of variables method and the inner product defined on L^2 [0,l], the solution is constructed in the form of a Fourier series with respect to the eigenfunctions of a corresponding Sturm-Liouville eigenvalue problem including fractional derivative in Caputo sense used in this study. Illustrative example presents the applicability and influence of separation of variables method on fractional mathematical problems.
Evaluación de destrezas de pensamiento crítico: validación de instrumentos libres de cultura
Authors: Vásquez-Alonso Ángel , Manassero-Mas Maria Antonia
Published: September 2020

Es un lugar común que el pensamiento crítico es una parte importante en la enseñanza y aprendizaje de las materias STEM (ciencia, tecnología, ingeniería y matemáticas). Sin embargo, la investigación sobre pensamiento crítico ha dedicado más atención a los programas de enseñanza que a la igualmente necesaria tarea de evaluar los efectos de esos programas, de modo que los estudios empíricos de evaluación constituyen la excepción más que la regla en este tema. Este estudio presenta la validación piloto de dos pruebas de evaluación de destrezas de pensamiento crítico con dos grupos naturales de estudiantes de primaria y secundaria, que participan en un programa de aprendizaje basado en pensamiento. Las pruebas se diseñan adaptadas a las destrezas enseñadas y la edad de los estudiantes, combinando cuestiones de instrumentos publicados y cuestiones figurativas de nuevo diseño, independientes de la cultura y de los conocimientos escolares. Los resultados muestran una relación positiva entre las puntuaciones de las pruebas y los criterios de validación independientes y externos (calificaciones escolares y notas del programa de pensamiento de los estudiantes). Se aporta una correlación excepcionalmente alta en una de las prueba y valores aceptables de la fiabilidad de las escalas; además, las nuevas cuestiones figurativas presentan mejor fiabilidad y validez que las verbales. Finalmente, se discuten las aportaciones de este estudio piloto, la toma de decisiones futuras para mejorar los instrumentos presentados y el desarrollo del diseño de instrumentos libres de cultura a medida, iniciados en este estudio.

Representações para Professor em Artigos de Opinião Jornalísticos sob a Perspectiva Sistêmico-funcional
Authors: Chagas Nédilã Espíndola , Schmidt Ana Paula Carvalho
Published: September 2020

O presente artigo tem por objetivo analisar as representações para professor e seus referentes em artigos de opinião de autoria de professores, publicados no blog Educação e Mídia, que é parte do conteúdo oferecido pela versão online do periódico paranaense Gazeta do Povo. Para tanto, tomamos por pressuposto teórico a Linguística Sistêmico-Funcional (HALLIDAY, 2014), mais especificamente o sistema de transitividade que realiza a metafunção ideacional, muito embora também tenhamos recorrido à metafunção interpessoal. A análise nos possibilitou observar que aos professores são manifestadas diferentes representações das quais se destacam a de responsável pelo processo de ensino e aprendizagem e pelas relações afetivas que repercutem na formação do educando como cidadão.
Logical Forms Depend on Semantic Models: the Illusory Disjunctive Sentences as Pieces of Evidence
Authors: López-Astorga Miguel
Published: September 2020

A teoria dos modelos mentais é capaz de explicar um amplo espectro de fatos relacionados à cognição. No entanto, pode-se pensar que o problema com essa teoria do ponto de vista linguístico é que ela ignora a forma lógica e, portanto, a sintaxe. Foi proposto que existem maneiras de vincular a teoria dos modelos mentais a estruturas formais. Contudo, permanece um problema em propostas desse tipo: a detecção de formas lógicas sempre parece depender de possibilidades icônicas como as suscitadas pela teoria mencionada, o que, por sua vez, parece significar que esse último arcabouço se refere a aspectos realmente básicos da cognição e da linguagem. Este artigo tenta mostrar que tudo isso está correto recorrendo a um exemplo que parece não ter sido estudado em profundidade a partir dessa perspectiva: o caso das sentenças ilusórias disjuntivas, ou seja, sentenças disjuntivas que as pessoas tendem a considerar verdadeiras e que na verdade não são.

Dans cet article, nous avons pour but de discuter des relations entre langage et travail, en focalisant sur le rôle potentiellement formatif des genres textuels dans le contexte du travail d’enseignement. Nous présenterons les genres qui circulent dans les situations de travail enseignant et ceux qui peuvent être produits à des buts formatifs, en distinguant ceux qui circulent dans la sphère de travail ceux qui ont un potentiel d’apprentissage et/ou de développement. Notre étude se base sur l’orientation épistémologique de l’Interactionnisme Social et se sert de trois cadres théoriques : celui de l’Interactionnisme Socio-discursif, d’une part ; et ceux de la Clinique de l’Activité et de l’Ergonomie de l’Activité des Professionnels de l’Education, d’autre part. Nous montrerons, de manière spécifique, une analyse d’une auto-confrontation et nous discuterons de son potentiel pour le développement des enseignants et pour la formation. Nous discuterons ainsi du rôle des verbalisations sur la situation de travail dans le processus de formation de l’enseignant, à travers des genres produits en situation de travail qui constituent une activité symbolique dans laquelle le langage devient un instrument de formation et de développement.

Petrophysics and paradigms of oil and gas geology
Authors: Khitrov Aleksey M. , Danilova Elena M. , Konovalova Irina N. , Popova Marina N.
Published: September 2020

The main provisions of the current paradigm of prospecting, exploration and production of hydrocarbons, which are based on petrophysics and seismic exploration, are considered. It is shown that within its framework it is possible to apply any new ideas about the structure of natural reservoirs, the origin and migration of hydrocarbons.
This paradigm will make it possible to move to the preparation of a qualitatively new resource base of the oil and gas complex through the discovery and development of hydrocarbon deposits in the best natural reservoirs with the best petrophysical parameters, high density of light oil and gas reserves, and high well production rates.
New highly profitable hydrocarbon deposits will be discovered in areas with developed infrastructure, mainly in well-known oil and gas provinces.
Oil of the XXI century: a new paradigm
Authors: Zapivalov Nikolay P.
Published: September 2020

The scale of risks, uncertainties, errors and disasters associated with the prospecting, exploration and production of hydrocarbons that has accumulated to date makes it necessary to rethink the fundamental principles of the oil and gas industry. After 70 years of educational, practical and scientific work in petroleum geology, developing the foundations of geofluidodynamics of oil and gas-saturated systems, the author came to the conclusion about the need to develop a new paradigm. The main author’s petro-geological paradigm is that an oil reservoir is a living fluid-rock system, the state and parameters of which can rapidly change in a continuous mode under the influence of natural and man-made factors in accordance with the laws of spontaneous self-regulation. Suggestions and recommendations are made for the competent management of the technological process of oil production.

Published: September 2020

Self-propping fracturing (in-situ proppant) has become an area of increasing interest in the development of fracturing technology over the past several years. In this paper, we review previous developments in this field and introduce latest research on self-propping fracturing technology. We identify the principles, key processes, and advantages behind the technology and introduce the properties of the liquids and solids involved. We developed a phase-change regulator and first carried out a physical distribution simulation test on the fluids and solids used. We also introduce the first-ever field test of self-propping fracturing liquid in volume fracturing of an unconventional oil well. This technology solves the technical difficulties associated with unconventional sand fracturing, especially those concerning the improvement of the fracture-controlled reserves. Its successful implementation provides new design concepts and advances technological change in the hydraulic fracturing industry.
Effect of Nanoparticle Shape on Viscoelastic Surfactant Performance at High Temperatures
Authors: Hanafy Ahmed , Najem Faisal , Nasr-El-Din Hisham A.
Published: September 2020

Viscoelastic surfactants (VESs) have been used for acid diversion and fracturing fluids. VESs were introduced because they are less damaging than polymers. VESs' high cost, low thermal stability, and incompatibility with several additives (e.g., corrosion inhibitors) limit their use. The goal of this study is to investigate the interaction of VES micelles with different nanoparticle shapes to reduce VES loadings and enhance their thermal stability.

This work examined spherical and rod-shaped nanoparticles of silica and iron oxides. The effects of particle size, shape, and surface charge on a zwitterionic VES micellization were conducted. The physical properties were measured using ζ-potential, dynamic light scattering (DLS), and transmission electron microscopy (TEM). The rheological performances of VES solutions were evaluated at 280 and 350°F using a high-pressure/high-temperature rotational rheometer. The proppant-carrying capacity of the fracturing fluids was evaluated using a high-pressure/high-temperature see-through cell and dynamic oscillatory viscometer. The fluid loss and formation damage were determined using corefloods and computed-tomography scans.

The interaction between nanoparticles and VES is strongly dependent on the VES concentration, temperature, nanoparticle characteristics, and concentration. The spherical particles at 7-lbm/1,000 gal loading extended the VES-based-fluid thermal stability at VES loading of 4 wt% up to 350°F. The nanorods effectively enhanced and extended the thermal-stability range of the VES system at VES concentration of only 2 wt%. Both particle shapes performed similarly at 4 wt% VES and 280°F. The addition of silica nanorods extended the thermal stability of the 4 wt% VES aqueous fluid, which resulted in an apparent viscosity of 200 cp for 2 hours. The addition of rod-shaped particles enhanced the micelle to micelle entanglement, especially at VES loading of 2 wt%. The use of nanoparticles enhanced the micelle/micelle networking, boosting the fluid-storage modulus and enhancing the proppant-carrying capacity. The addition of nanoparticles to the VES lowered its fluid-loss rate and minimized formation damage caused by VES-fluid invasion.

This research gives guidelines to synthesize nanoparticles to accommodate the chemistry of surfactants for higher-temperature applications. It highlights the importance of the selected nanoparticles on the rheological performance of VES.

Backgroud: Diabetes mellitus is a common chronic disease and a severe public health issue. The incidence trends for type 1 diabetes (TIDM) and type 2 diabetes (T2DM) have rarely been studied on a global scale. We aimed to determine the temporal and geographical trends of diabetes globally.Methods: Data on diabetes mellitus, including incidence, prevalence from 1990 to 2017 were obtained from the 2017 Global Burden of Disease study. We calculated the estimated annual percentage changes (EAPCs) in age-standardized incidence rate (ASIR) of diabetes mellitus according to sex, region, and disease type.Results: The worldwide incident cases of diabetes mellitus has increased by 102.9% from 11,303,084 cases in 1990 to 22,935,630 cases in 2017 worldwide, while the ASIR increased from 233.58/100,000 persons (95% UI, 218.95–249.37) to 284.56/100,000 persons (95% UI, 262.17–309.71) in this period [EAPC=0.87, 95% confidence interval (CI):0.79–0.96]. The global ASIRs of T1DM and T2DM both demonstrated significant increase during 1990-2017, with EAPCs of 0.34 (95% CI:0.30–0.39) and 0.89 (95% CI:0.80–0.97), respectively. The ASIR trends also varied considerably by regions and countries. The increase in ASIR was greatest in high sociodemographic index regions (EAPC=1.05, 95% CI:0.92–1.17) and lowest in low-SDI regions (EAPC=0.79, 95% CI:0.71–0.88). Conclusions: Both the number of incident cases and ASIR of diabetes mellitus increased significantly during 1990-2017 worldwide, but the temporal trends varied markedly across regions and countries.

Background: Uterine clear cell carcinoma (UCCC) is a rare histological type of endometrial cancer with poor prognosis and high risk of tumor relapse. Although adjuvant chemotherapy (CT) and/or radiotherapy (RT) are often recommended for early stage UCCC patients, the effectiveness of these treatment strategies remains unclear. Methods: Systematic review and meta-analysis were applied to evaluate treatment-related outcomes of stage I-II UCCC patients. Search strategy was applied using electronic databases until June 1st, 2019. Inclusion criteria were retrospective, observational and prospective studies that reported outcome of UCCC patients receiving adjuvant therapy. Clinical endpoints like overall survival (OS) and progression-free survival (PFS) were evaluated. Data were extracted by two independent reviewers and a meta-analysis was performed. Results: 12 articles with a total of 3845 patients were analyzed. Overall, adjuvant CT after surgery could improve 5 year-OS significantly compared to patients without CT (odds ratio (OR): 0.75, 95% confidence interval (CI): 0.58-0.95; p=0.02). In comparison, RT could also improve OS in UCCC patients of early stage (OR: 0.61, 95% CI: 0.46-0.82; p=0.001) compared to the patients without RT, in US and Europe patients. Lastly, when comparing the patients undergoing both CT and RT with those receiving CT or RT alone, no further improvement in OS was observed (OR: 0.95, 95% CI: 0.53-1.72; P=0.88). Conclusions: Either CT or RT after surgery could improve the OS of early stage of UCCC patients. However, combinatorial CT and RT treatment did not improve the OS compared with CT or RT treatment alone.

Background: The control of schistosomiasis has been centered to date on a single drug, praziquantel, with shortcomings including treatment failure, reinfection, and emergence of drug resistance. Drug repurposing, combination therapy or nanotechnology were explored to improve antischistosomal treatment. The aim of the present study was to utilize a novel combination of the three strategies to improve the therapeutic profile of praziquantel. This was based on a fixed-dose nanocombination of praziquantel and miltefosine, an antischistosomal repurposing candidate, co-loaded at reduced doses into lipid nanocapsules, for single dose oral therapy.Methods: Two nanocombinations were prepared to provide 250 mg praziquantel-20 mg miltefosine/kg (higher fixed-dose) or 125 mg praziquantel-10 mg miltefosine/kg (lower fixed-dose), respectively. Their antischistosomal efficacy in comparison with a non-treated control and their praziquantel or miltefosine singly loaded counterparts was assessed in murine schistosomiasis mansoni. A single oral dose of either formulation was administered on the initial day of infection, and on days 21 and 42 post-infection. Scanning electron microscopic, parasitological, and histopathological studies were used for assessment. Preclinical data were subjected to analysis of variance and Tukeyʼs post-hoc test for pairwise comparisons.Results: Lipid nanocapsules (~58 nm) showed high entrapment efficiency of both drugs (> 97%). Compared to singly loaded praziquantel-lipid nanocapsules, the higher nanocombination dose showed a significant increase in antischistosomal efficacy in terms of statistically significant decrease in mean worm burden, particularly against invasive and juvenile worms, and amelioration of hepatic granulomas (P ≤ 0.05). In addition, scanning electron microscopy examination showed extensive dorsal tegumental damage with noticeable deposition of nanostructures.Conclusions: The therapeutic profile of praziquantel could be improved by a novel multiple approach integrating drug repurposing, combination therapy and nanotechnology. Multistage activity and amelioration of liver pathology could be achieved by a new praziquantel-miltefosine fixed-dose nanocombination providing 250 mg praziquantel-20 mg miltefosine/kg. To the best of our knowledge, this is the first report of a fixed-dose nano-based combinatorial therapy for schistosomiasis mansoni. Further studies are needed to document the nanocombination safety and explore its prophylactic activity and potential to hinder the onset of resistance to the drug components.
Learning Experiences Among GP Registrars After a Focused Cardiac Ultrasound Training Program: A Qualitative Interview Study
Authors: Sjöström Rita , Klockmo Carolina , Söderström Lars , Nilsson Gunnar
Published: September 2020

Background: Until recently, clinical ultrasound technology was limited to the hospital-based disciplines, and few studies assessed training in focused cardiac ultrasound (FCU) in primary care. We designed an interview study among general practitioner (GP) registrars taking part in an FCU training program and discussed their experiences compared to their documented skills.Methods: This qualitative content analysis used an inductive approach. Five GP registrars and their tutor participated in semi-structured individual interviews during April–July 2017. Participants were interviewed after they each had conducted 20 supervised and 7–10 independent examinations and were encouraged to complete self-directed study using video tutorials on web-based platforms. FCU examinations of study patients recruited from primary care clinics were conducted with a hand-held device (Vscan 1.2) at the Centre of Clinical Research, Östersund Hospital, Sweden. Results: We identified two categories of information: the prerequisites of learning FCU and the acquisition of skills for professional development. Combining theoretical education with hands-on tutorials was an essential part of FCU learning. However, participants suggested that the training program should include group tutorials to give a deeper understanding of scanning positions and a reference standard for evaluating the FCU recordings. In skill acquisition, participants experienced more confidence in performing the technical aspects of FCU than in interpreting the images to evaluate cardiac function. The participants saw several possibilities for applying FCU in primary care, including as a screening tool in rural clinics or to support referrals to specialized care.Conclusions: After completing 20 supervised FCU training sessions, previously inexperienced examiners felt that assessment of cardiac function was more difficult than acquiring adequate ultrasound images. To gain confidence in assessment of cardiac function, respondents suggested personal feedback and group tutorials with discussion of clinical examples in smaller groups for improvement of learning. Demographic differences between patients seen in hospital wards and primary care clinics should also be considered in the design of FCU training programs.
