Published: February 2023

ABSTRACT

Presentation-Practice-Production (PPP) has been a common teaching model to improve grammar understanding. A videotaped classroom found on YouTube uses the PPP model with proper elicitations that create student-centered. This study aims to investigate the number of elicitation questions in each stage of PPP and its role to stimulate learning that most benefits students. A quantitative method was used to determine the most frequently used type of elicitation question in each stage. In addition, the data of the selected transcript extracts is qualitatively analyzed using conversational analysis. The result shows that closed-ended questions are mostly used in the presentation phase. Meanwhile, open-ended questions are mostly used in the practice and production phases. It is concluded that a close-ended question fits the stage that needs high guidance from the teacher like when lecturing. Meanwhile, the open-ended question is suitable for a stage that is freer for students to practice and explore.

La presente tesis doctoral establece la utilización de un electrolito a base de cloruro de colina y urea (ChCl/Urea) en una relación molar 1:2, este tipo de medio pertenece a una serie de mezclas altamente viscosas con bajo punto de fusión, las cuales reciben el nombre de disolventes eutécticos profundos (DES por sus siglas en inglés). Dicho electrolito se usó para llevar a cabo la síntesis de estructuras metálicas (Zn, Fe y Al) y sus aleaciones, al variar no solo condiciones hidrodinámicas (usando un electrodo de disco rotatorio) sino también de temperatura y potencial aplicado sobre un electrodo de carbón vítreo. En la realización de esta tesis se usaron formalismos teóricos para obtener información, es decir, parámetros cinéticos derivados de la electrodeposición de metales y aleaciones en DES, donde fue posible estimar coeficientes de difusión, frecuencias de nucleación, densidades numéricas de sitios activos, entre otras. El arreglo de la celda que se empleó, así como las técnicas electroquímicas que se utilizaron se detallan en la metodología de este documento. Adicionalmente, se realizó una revisión bibliográfica que comprende no sólo el uso de DES para la deposición electroquímica de Zn, Fe y Al, y sus aleaciones, sino también la utilización de medios acuosos pese a las dificultades que este tipo de electrólitos puedan tener, dado que es indispensable comprender el trabajo que se ha efectuado para tener un punto de comparación, así como el que no se ha realizado para explorar áreas de oportunidad en la electrodeposición de metales y aleaciones en DES.
Lawmaking in Dutch Sri Lanka
Authors: Rupesinghe Nadeera
Published: February 2023

Navigating Pluralities marks a break in understanding the history of Roman-Dutch law in Sri Lanka. Methodologically, it challenges socio-legal studies that concentrate on major jurisdictional conflicts alone, emphasizing the lived experience of everyday practices of judicial forums. It uncovers the navigation of plural practices in the Landraad, a judicial forum set up by the Dutch East India Company in seventeenth-century Sri Lanka. A choice of laws came into play in that forum, that choice being significant at varying degrees for different areas of the law such as evidence, inheritance, land, and marriage law. While there was inevitable conflict, the local normative order was as much a social fact for the early colonial rulers as Roman-Dutch law. This is contrary to the received wisdom of the ages that Roman-Dutch law was imposed on the Sinhalese of the maritime provinces under Dutch control. When translated into everyday lives, such adoption of plural practices could rebound on coloniser and colonised in unexpected ways, revealing the complexities of colonial law in practice.

Aims

Several causes have been reported for coronary artery ectasia (CAE), mostly atherosclerosis and tunica media abnormalities. The main aim of the present study was to investigate if CAE extension differs in distinct clinical settings.

Methods

Three hundred and forty-one patients with diagnosis of CAE were identified among 9659 coronary angiographies and divided into four groups according to the patient's admission diagnosis: stable or unstable angina (S-UA), myocardial infarction (MI), aortic disease, aortic valvular disease (AVD). S-UA and MI were subgrouped according to the presence of obstructive coronary artery disease (OCAD). Multivariable logistic regression was used to investigate the relationship between clinical diagnosis and CAE extension as expressed by Markis classification and number of coronary vessels affected by CAE.

Results

No significant differences in CAE extension were found among the four groups, in terms of vessels affected by CAE (P = 0.37) or Markis class (P = 0.33). CAE was not related to the extension of OCAD as assessed by the Gensini score, which was higher in MI and S-UA groups (P < 0.01). However, when ischemic patients were sub-divided on the basis of the presence of OCAD, MI without obstructive coronary artery disease (MINOCA) was associated with a higher extension of CAE in terms of Markis class 1 (OR 5.08, 95% CI 1.61–16.04; P < 0.01).

Conclusion

The extension of CAE is comparable in patients referred to coronary angiography for different clinical scenarios, including S-UA, MI, aortic disease, and AVD; however, patients with MINOCA were associated with a higher extension of CAE.

Fatty acid correlations with HOMA-IR and HOMA-% β are differentially dictated by their serum free and total pools and flaxseed oil supplementation
Authors: Barre Douglas E. , Mizier-Barre Kazimiera A. , Griscti Odette , Hafez Kevin
Published: February 2023

Objective.The intent of the present study was to test two hypotheses. The primary hypothesis was that there would be differences between blood serum individual free fatty acids (SIFFA) and serum individual total fatty acids (SITFA) in terms of their different relationships (correlations) to each of homeostatic model assessment-individual insulin resistance (HOMA-IR) and homeostatic model assessment-individual insulin resistance-percentage β-cell function (HOMA-% β) remaining in human type 2 diabetic patients with pre-flaxseed oil (FXO) and pre-safflower oil (SFO) administration. The secondary hypothesis was that FXO (rich in alpha-linolenic acid, ALA) supplementation would alter these correlations differently in the SIFFA and STIFFA pools in comparison with the placebo SFO (poor in ALA).

Methods.Patients were recruited via a newspaper advertisement and two physicians. All patients came to visit 1 and three months later to visit 2. At visit 2, the subjects were randomly assigned (double-blind) to flaxseed or safflower oil (placebo) treatment for three months until visit 3.

Results.There were pre-intervention differences in the SIFFA and STIFA pool’s relationships with each of HOMA-IR and HOMA-% β. These relatioships remained either unchanged or became significant after intervention (treatment or placebo). There was a negative correlation found between HOMA-IR and serum free ALA (SFALA) mol % after FXO. Serum total ALA (STALA) mol % had no significant correlations with HOMA-IR and HOMA- % β before and after flaxseed oil administration.

Conclusions.The SIFFA and SITFA pools have different relationships with HOMA-IR and HOMA-% β for each of pre- and post-intervention. It is concluded that the data support both the primary and the secondary hypotheses indicating that they are correct.

Objective. Ovarian torsion is a gynecological emergency that occurs mostly during the female reproductive years due to ovarian masses or surgical manipulation. This work aims to explore the probable protective effect of leptin on rat ovaries due to ischemia-reperfusion (IR) injury.

Methods. Wistar albino rats were divided into four groups: 1) control group; 2) ovarian IR group (OVIR); 3) leptin group I [OVIR + leptin (10 µg/kg body weight, b.w.)]; and 4) leptin group II (OVIR + leptin (100 µg/kg b.w.)]. Serum levels of estradiol and anti-Mullerian hormone (AMH) were measured. Levels of oxidative stress and inflammatory markers in ovarian tissue were determined along with the expression of sirtuin 1 (Sirt1), nuclear erythroid factor-2 (Nrf2), cyclooxygenase-2 (COX-2), nuclear factor kappa (NF-κB), toll like receptor-4 (TLR4), and caspase-3.

Results. Serum estradiol and AMH levels were decreased with increased expression of COX-2, TLR4, caspase-3, and NF-κB and decreased expression of Sirt1and Nrf2 in ovary of the OVIR group, which were improved by exogenous administration of both leptin doses.

Conclusion. Leptin administration dose-dependently reduced the severity of OVIR injury via modulation of Sirt-1/Nrf2 and TLR4/NF-kB/caspase-3 signaling pathways. Thus, leptin may be used as an adjuvant measure to prevent ovarian damage and improve the outcomes. However, clinical studies are needed to evaluate these results in humans.

Quarry, S. Miguel Island, 2021. Author’s photo
 
Urban environmental agency is visible through its materialization, nonetheless, the technological systems behind its production often remain concealed. Buildings and infrastructures, as technological products, are just a small visible part of a complex system – the excavation, exploitation, consumption, erosion, and transformation of basalt stones are among some of the technological procedures behind the physicality of landscapes. The extraction of raw materials from which the island is built leads to operations of material addition or subtraction – and the island reinvents itself, within a network of sites of exploitation and provision.
Through a photographic testimony of a basalt quarry in S. Miguel Island, this paper intends to explore the intertwinement between the extraction sites and its architectural manifestations. In this light, the acknowledgment of these invisible production sites is understood as a form of care for the possible futures of the island’s materialities.
Today, as the concern for the environmental impacts of construction is ever more present on the global agenda, along with a shortage of many resources for civil construction activities, a critical awareness of the territories’ building materials urges. In this sense, to interrogate the island’s dependencies through an urban lens seems to be essential for a control of architectural materials. These landscapes disclose part of the extractions that produce the island, and considering that material and environmental impacts are also located in the future, this analysis seeks to engage urban production with a practice of care.

is one of the regions with potential renewable energy sources, includinghydropower, namely the Micro Hydro Power Plant (PLTMH). The main problem with hydropoweris the flow of water that does not flow continuously throughout the year. A micro hydro that isplaced in a certain location requires a turbine in accordance with the characteristics of theexisting location. In this study, a turbine was designed to obtain a new type of Snail-Lie turbinethat accommodates all existing location parameters. In this turbine, there are variations in theform of gaps or spaces in each particular blade to trap water so that it can increase the torque,where this torque will affect the turbine output. The research method used is to findmathematical models of the Snail-Lie 4 Snail and 8 Snail turbines, make a prototype model tobe tested in the laboratory, make a real Snail-Lie turbine model for field trials. The resultsshowed that the addition of the number of snails from 4 snails to 8 snails caused the turbine'sperformance to increase, this is because the number of snails will affect the performance of theturbines, because the snail functions as a water trap so that it can be used as thrust for theturbine when it rotates. The highest output obtained is at the nozzle position 0° and the nozzleangle of 20° using a snail-lie 8 snail tubing which produces 166.9 rpm turbine rotation, 1086.8rpm generator rotation, 0.707 volt generator voltage, 0.189 watt generator power, and torqueamounting to 0.01 Nm, and an efficiency of 20.8%.

Turbine is a component that plays an important role as an energy converter to be ableto generate electricity in the Micro Hydro Power Plant (MHP). The turbine used in this prototypeis a Pelton tubine. The Pelton turbine is a type of impulse turbine consisting of two blades as aprelude receiver for water jets from the nozzles by utilizing high water heads even though thewater discharge is small. This research will discuss the effect of the number of blades on therotation produced by the Pelton turbine and generator so that it can be seen the voltage,current, power produced that affects the torque value and efficiency obtained on the prototypeMHP. This study aims to obtain a turbine runner with the number of blades that can produce thehighest efficiency, then a variation of the pelton turbine runner is made with different number ofblade parameters from the runner with the number of blades according to the calculationobtained from the reference. Variations in the number of blades used are 14 blades, 16 blades,18 blades, 20 blades, and 22 blades. The results showed that the addition of the number ofblades starting from the smallest caused the performance of MHP to increase, the highestoutput obtained was using a turbine runner with a number of 22 blades which resulted in aturbine rotation of 852.2 rpm before the generator coupled and 497.2 rpm after coupling thegenerator. Generator rotation is 2133.8 rpm, Generator Voltage is 15.72 volts, Generator poweris 33.7 Watts and Torque is 0.6 Nm. The efficiency value using a runner with a number ofblades 22 is 4.54%. The resulting efficiency value is very low because the MHP prototype in                                                                                                          generation is less effective and uses a small generation capacity DC generator, so it cannotgenerate power as much as hydraulic power.

Water reservoirs are temporary water reservoirs, usually placed at the highest. The communityplaces or installs water reservoirs above the house by using gravity so that the water can run downswiftly. In general, to get clean water, people use PDAM services or use well water. Generally, in urbanareas, the water sources used to supply water reservoirs come from PDAMs or wells (boreholes). In theclean water storage system using an upper reservoir has several problems, such as monitoring theavailable water capacity in the borehole which cannot be known so that the pump will operate for a longtime to fill water and cause damage to the pump, due to the difficulty of monitoring and controlling. Thecondition of the upper reservoir water storage is therefore designed in this study with a prototype"WATER SANDING SYSTEM USING UP TANDON AUTOMATICALLY BASED ONMICROCONTROLLER" which can be monitored via SMS and manually.

The large starting current in the starting process has the potential to damage theinduction motor. In minimizing the risk of damage, proper starting methods are needed. TheDirect On Line (DOL) method is a starting method commonly used in induction motors becauseof its economical installation and high work efficiency. The starting method which also has goodwork efficiency is the Variable Speed Drive (VSD). There needs to be a comparative analysisbetween the two methods to find out how the performance of the two methods is.Research results, the ongoing performance of the two starting methods on the fanmotor for cooling towers shows that the performance of the VSD method is superior to that ofthe DOL method. Starting performance on an induction motor can be seen from the efficiencyand economic value of the DOL and VSD methods. This performance is of course taking intoaccount the current, rotation speed and the resulting output power.
