This study focused on the effectiveness of the Metacognitive and Explicit Approaches on the improvement of the Grade 9 students’ academic achievement in Chemistry based on their pre-test and post-test scores. The respondents of the study were composed of 80 Grade 9 students with the same level of achievements in science. This study employed the Experimental Research Design, specifically, the Pre-test / Post-test Explicit approach design. With this design, the researcher identified two whole classes of the Grade 9 students for the school year 2014-2015. These classes were randomly selecte

Since radial forces always occur during tapping due to the uneven load distribution on the individual teeth, the tool model represents an essential part of the entire closed-loop model.

Abstract:
AbstractThe current principles and pillars in the management of gunshot maxillofacial injuries have largely been the result of an exhaustive experimental approach spanning centuries of warfare. However, while medical professionals endlessly strive to revolutionize healthcare in combat injury, there are simultaneous efforts directed towards creation of new and ever more lethal arms and ammunition. Consequently, these doctrines continue to undergo significant transformations with a contemporary understanding of war injuries as well as the advent of new surgical materials and modern instrumentati

Abstract:
The flow behavior of the two-blade MERIT rotor in hover, focusing on both pre-stall and stall regimes, is investigated through a comprehensive numerical-experimental approach. The study leverages unsteady RANS simulations to compute rotor thrust and power polars and validates them against experimental measurements. Valuable insights are provided into the capabilities of unsteady RANS methods and modern turbulence models for predicting rotor performance across these critical operating conditions. Furthermore, the numerical model incorporates blade deformations by implementing the experimentally

Abstract:
Failures of structural and mechanical components have long been attributed to environmentally assisted cracking (EAC). The umbrella of EAC encompasses several phenomena, including stress corrosion cracking (SCC), corrosion fatigue (CF), hydrogen embrittlement (HE) and liquid metal embrittlement (LME). The latter, LME, has resulted in the failure of components in petrochemical and aeronautical industries, among others. The effects are detrimental, with crack tip velocities on the order of centimeters per second and failures occurring rapidly. Previous research has provided numerous underlying m

Abstract:
The pre-heating of engine coolant using electrical and fuel-based pre-heaters has been practiced for decades. There are many valid reasons for pre-heating engines such as increasing fuel economy, reducing pollution from combustion, reducing engine wear and increasing comfort. Those reasons are particularly true in colder climates where cars are used for short trips of up to 10 minutes or 5 kilometers. In this paper an unconventional approach for pre-heating engines before starting is studied. The pre-heating is accomplished by assuming storage of a certain amount of the engine’s hot coolant in

Abstract:
Injecting a polymer solution into a porous medium significantly increases the modeling complexity, compared to model a polymer bulk solution. Even if the polymer solution is injected at a constant rate into the porous medium, the polymers experience different flow regimes in each pore and pore throat. The main challenge is to assign a macroscopic porous media “viscosity” to the fluid which can be used in Darcy law to get the correct relationship between the injection rate and pressure drop. One can achieve this by simply tabulating experimental results (e.g., injection rate vs pressure drop).

We conduct a discrete choice experiment with leaders of a random sample of 164 Peruvian indigenous communities (ICs) - to our knowledge, the first use of rigorous stated preference methods to analyze land titling. We find that: (i) on average, IC leaders are willing to pay US$35,000-45,000 for a title, roughly twice the per community administrative cost of titling; (ii) WTP is positively correlated with the value of IC land and the risk of land grabbing; and (iii) leaders prefer titling processes that involve indigenous representatives and titles that encompass land with cultural value.
