Összefoglalás
Kutatómunkánk elsődleges célja a repce és napraforgó tarlómaradvány N-tartalmának Magyarországra jellemző reprezentatív értékeinek meghatározása volt az országos statisztikai termésadatok és a növényminták N-tartalmának laboratóriumi mérése alapján. Továbbá összefüggést kerestünk a talaj és a növény N-tartalma között.
Vizsgálataink során egész Magyarországot reprezentáló mintavételt végeztünk repce és napraforgó állományokból, 126 növény- és mintegy 70 talajmintát gyűjtöttünk be, melyek N-tartalmát laboratóriumban határoztuk meg.
Kiszámoltuk a két növény országos termésátlagával keletkező tarlómaradvány mennyiségét és a mért N-tartalom értékek alapján megbecsültük a tarlómaradványok N-tartalmát. Összefüggést mutattunk ki a talaj és a növény N-tartalma között. Esettanulmány jeleggel kiszámítottuk egy olyan terület N-mérlegét, amelyre vonatkozóan rendelkezésre áltak a számításhoz szükséges adatok.
Eredményeink legfőbb gyakorlati vonatkozása, hogy a növényi maradványok felszecskázása és talajba dolgozása útján visszapótolt N mennyiségének meghatározása hosszabb távon hozzájárulhat a növénytáplálás költségeinek csökkentéséhez, illetve a természeti erőforrásokkal való takarékosabb gazdálkodáshoz.

Propósito:este artículo revisa algunas concepciones del pensamiento crítico y destaca
su importancia para la educación. Descripción: primero, presenta algunos enfoques fi-
losóficos y psicológicos del pensamiento crítico y su influencia en las políticas educativas
internacionales y nacionales como un medio para fomentar la ciudadanía activa y, a su
vez, el desarrollo sostenible. En segundo lugar, destaca la relación entre el pensamiento
crítico y el Aprendizaje Integrado de Contenido y Lenguas Extranjeras (aicle). En tercer
lugar, los autores de este artículo insisten en el papel vital que tienen los maestros en el
desarrollo del pensamiento crítico. Punto de vista: el concepto de pensamiento crítico
ha sido abordado por diferentes académicos a través de la historia. Aunque ellos pueden
diferir, todos tienen características comunes, como la disciplina intelectual, la integridad,
la libertad, la ciudadanía, la creatividad y la empatía. Por lo tanto, el desarrollo del pensa-
miento crítico debe ser inherente a la educación, ya que las sociedades necesitan ciuda-
danos que faciliten su progreso. Un ejemplo de cómo se puede desarrollar el pensamiento
crítico en la educación se ilustra a través de la implementación de aicle en las clases de
idiomas. Conclusión: teniendo en cuenta que los estudiantes pasan mucho tiempo en la
escuela, los maestros están llamados a ayudar a la familia a desarrollar las habilidades de
pensamiento crítico de nuestros estudiantes durante sus prácticas de enseñanza regulares.

Authors: Varma Ankur , Varshney Varma Aditi , Joseph Jebin 
Published: November 2019

Background: Acute appendicitis is a diagnostic dilemma for surgeons due to wide array of differential diagnosis and sometimes due to atypical presentation. Diagnosis using sonography, which is the most common modality, has a very low specificity and sensitivity. In such cases it puts a surgeon in dilemma especially in an emergency setting. The integration of clinical scores into the diagnostic process in acute appendicitis has been shown to improve decision making and reducing the negative appendectomy.Methods: This is a prospective observational study attempted to compare the efficiency of Alvarado and Raja Isteri Pengiran Anak Saleha Appendicitis (RIPASA) score, in pre-operative diagnosis of acute appendicitis and to correlate these scores with histo-pathological diagnosis.100 cases satisfying inclusion and exclusion criteria were selected for study. Based on detailed history and thorough clinical examination, diagnosis of acute appendicitis was made.Results: Sensitivity for detecting acute appendicitis was found to be higher using RIPASA score. Negative appendectomy rate by RIPASA and Alvarado scoring systems were 11.5 and 19.2% meanwhile it was 12% with sonography.Conclusions: In the diagnosis of acute appendicitis, clinical scoring is a fast, simple, reliable, non-invasive, repeatable and safe diagnostic modality without extra expense and complications. This study shows RIPASA is a better scoring system than Alvarado in the diagnosis of acute appendicitis.
FOREIGN INVESTMENT AND THE POLITICAL ECONOMY OF INDONESIAN CAPITAL MARKET IN 2015-2016
Authors: Al-Fadhat Faris , Raihan Nadhir Mohammad 
Published: November 2019

Purpose of the study: This article examines the impact of foreign investment—especially through the capital market—towards the economic stability and strategic policy in Indonesia. Despite being a member of G20, a group of states with the world’s highest Gross Domestic Products, Indonesia is still a developing state whose need for investment to support economic growth is high. On the other side, Indonesia has a low capital accumulation rate due to low people’s savings which inhibits the development projects. Therefore, the government prioritizes the incoming flow of foreign investment.
Methodology: This study applies the international political economy approach to provide critical analysis of Indonesian contemporary foreign investment, especially in the capital market. The data used is the investment activities through the Indonesia Stock Exchange during 2015-2016.
Main Findings: It argues that Indonesia’s considerable dependence on investment has enabled foreign investors to play the capital flow to influence the national economic stability for their interests. Such influence was a result of two strategies: (i) the transaction domination in the capital market through the Indonesia Stock Exchange, and (ii) the alliance with financial actors in accessing inside information—which is not commonly owned by domestic investors.
Implications/Applications: This study suggests that the politics of foreign investors has contributed towards the changes of government policies in the financial sectors to facilitate the process and to ensure the flow of foreign investment to Indonesia. Such policies include the government’s control of interest rates, fiscal policy, as well as currency stability through macroprudential regulation.
Novelty/Originality: Essentially, the capital market is not politically neutral. It has been used by foreign investors to augment their interests by dominating transactions and building political alliances at the domestic level.

Aim: To evaluate the marginal adaptation of provisional crowns made of acrylic and bisacrylic resins using different impression materials. Methods: a metal die and a matrix applied through a direct technique were used to fabricate the specimens. The impression materials used as a matrix were divided into four groups: Irreversible hydrocolloid (IH), laboratory silicone (LS), condensation silicone (CS), and addition silicone (AS). After the impression procedures, each matrix was loaded with the provisional prosthetic materials, Alike, Duralay, Protemp 4, and Structur 3 (n = 12). Marginal discrepancy was evaluated using a stereomicroscope at ×45 magnification. The images obtained were transferred to the Corel Draw X7 program, and the distances from the cervical margins of the specimen to the reference lines at the metal die were measured vertically. The data were analyzed by using 2-way ANOVA followed by the Tukey test (α=.05). Results: the acrylic resins had higher values ​​of marginal discrepancy compared to the bisacrylic resins. A statistically significant difference was found between all impression materials, and the irreversible hydrocolloid presented higher values of discrepancy (303.28–613.31 μm), whereas addition silicone had the lowest (48.61–190.06 μm). Conclusions: the bisacrylic resins had a better marginal adaptation compared to the acrylic resins. The addition silicone promoted a better marginal adaptation of the provisional prosthetic materials tested, followed by condensation silicone, laboratory silicone, and irreversible hydrocolloid.

Aim: The objective was to evaluate, quantitative and qualitative, the abrasive effect of three polishing systems on the monolithic zirconia ceramic. Methods: Thirty disk-shaped samples of Yttria Tetragonal Zirconia Polycrystal (Y-TZP) were randomly distributed in three groups (n = 10) according to polishing system: G1- Komet system (KO); G2 - CeraGloss system (CG); G3 - Eve Diacera system (EV). The surface roughness (Ra) was obtained with Rugosimeter in four different moments: a) initial - glaze sample (Ra0); b) after occlusal adjustment with diamond burs (Ra1); c) after polishing with the abrasive systems (Ra2); d) after polishing with felt disc and diamond paste (Ra3). Four additional samples were observed in scanning electron microscopy (SEM). Results: According to the Generalized Estimating Equation followed by the Bonferroni test (α = 0.05), the CG provided the lowest Ra2 (0.63 μm), not differing significantly from the KO (0.78 μm). The highest Ra2 was obtained with the EV (0.97 μm), which did not differ significantly from the KO. There was no statistical difference in Ra between the polishing with the abrasive systems (Ra2) and the final polishing with diamond paste (Ra3). SEM images showed that the polishing systems did not completely remove the grooves caused by the diamond burs during the occlusal adjustment. Conclusion: It was concluded that CG promoted smoother surface of the monolithic zirconia ceramic compared to EV, and intermediate smoothness was obtained with KO.

Deep-sea fans: tapping into Earth's changing landscapes
Authors: Hessler Angela M. , Fildani Andrea 
Published: November 2019

ABSTRACTDeep-sea fan sediments carry physical and chemical signatures that reflect the conditions under which their native landscapes evolved. Fans are long-lived, strongly net-depositional heaps of terrigenous debris, in some cases directly connected to a major river catchment. Here we use recent findings from deep-sea fans around the world to reason that modern fans might be our most continuous record of Cenozoic landscape change over large geographic scales. We opt for the use of multiple signatures that indicate major shifts in composition, because this approach avoids the problems inherent to measuring sediment flux alone. We emphasize the importance of looking across grain size, in particular at the clay fraction, the fastest carrier of sedimentary signals. Highlighted cases show the range of environmental signals preserved in deep-sea fans, observed over millennial and longer time scales, and how these signals help us understand the climate–surface interactions important to the carbon cycle. Revisiting legacy core with new techniques, in addition to future drilling campaigns, can provide the observational constraints needed to fill recognized gaps in climate models and landscape–erosion projections.

AbstractAlthough Bohai oilfield is still the main force of China offshore oilfield, some blocks had run out of production and need to be decommissioned. NB field which belonged to CNPC was in this state and has been decommission. In this job, most of procedure had been optimized. For pursued the best cutting performance, Abrasive Waterjet Cutting System (AWCS) had been used for multi-layer casing-strings and platforms cutting operation. Resistance force of casing-string pulled out and platform lifted had been calculated by using soil mechanics for choosing the suitable floating crane before the lifting operation. A numerical simulation was provided for checking the max displacement of platform after pile legs were cut. Moving sequence had been made based on the results of the simulation. The operation time of single casing-string had been reduced by using optimized working flow. With assistant of 150 tons class floating crane, 7-8 hours could be saved for each casing-string. Assemblage and dismantlement operation of casing-strings and pile legs cutting except the first and last casing-string or pile leg of the platform could be saved. The results of numerical simulation showed that platforms would have enough stability for decommission operation while all the pile legs had been cut. Based on the simulation results, all the platforms had been moved used one-stop operation after they had been cut and much time and money was saved. Based on the results of calculation of pulling out resistance force, 150 tons class and 500 tons class floating crane had been chosen for lifting casing-strings and platforms. During the job, the deviation of casing-strings was bigger than pile legs. The extra pulling loading was appeared for conductors. In order to find out the reason of that phenomenon, an experiment was conducted. The results of experiment could become a guidance for the next job.

Published: November 2019

Abstract
After drilling each section of a well, cement is placed in the annulus of the casing and the formation. The cement integrity must be ensured during the life cycle of the well or after abandonment. If for any reason, the cement lost its integrity, the consequences could be severe for personnel, equipment, and the environment. When the cement fail, leakages may occur through the cement pathways and sealant materials are used to plug these pathways. This study investigates a temperature activated epoxy resin sealant to evaluate the potential use of this sealant as an alternative to Portland cement in oil and gas wells. This study focuses on analyzing the rheological behavior of the sealant, the effect of temperature on the rheology and the curing time of the sealant, the penetrability of the sealant into small voids, and the blocking efficiency of the sealant. Experimental tests were conducted to evaluate the epoxy resin sealant including rheological measurements, density, injectivity, blocking efficiency, and mechanical properties. The findings of this study show that this sealant has low viscosity and Newtonian rheological behavior, low density as low as water, high injectivity and penetrability even in small gaps, ability to resist differential pressure higher 1000 psi, and extremely high compressive strength. This work demonstrates that epoxy resin sealant can be used effectively and safely in sealing cement voids.
