The use of cooperative learning to foster the enhancement of students' linguistic competence in essay writing in the english language undergraduate program at the university of Cordoba

In the pursue of bilingualism and language communicative competence with international standards, in Colombia, there has been an amplified emphasis on language use for communicative purposes. This has led to a preoccupying negligence towards language accuracy and correctness in English language classes. This has generated an elevated number of language learners who use the language inaccurately. This has become more disturbing by realizing future English language teachers make part of this community of inaccurate language users. Therefore, this research has undertaken the task of determining if the implementation of Cooperative Learning and its principles during classwork can benefit and improve university undergraduate students’ linguistic competence in a grammar class belonging to an English Language Teaching program. For this purpose, action research has been selected as a study design with the purpose of utilizing the data obtained for the learning betterment of the participants of the study. Also, the procedures for data collection have been implemented using mixed methods where error analysis was combined with Repeated-Measures Analysis of Variance and later triangulated with a questionnaire and an interview applied to the participants. The results, have displayed that the use of Cooperative Learning as an approach to learning in class can positively influence the improvement of participants’ linguistic competence and also generate positive attitudes towards this learning approach

Lunar rated fasteners

A catalog of fasteners is presented for a variety of applications to be used in a lunar environment. The fastening applications targeted include: covers, panels, hatches, bearings, wheels, gears, pulleys, anchors for the lunar surface and structural fasteners (general duty preloadable). The robotic installation and removal of each fastener is presented along with a discussion of failure modes. Structural performance data is tabulated for various configurations. Potential materials for the space environment are presented along with recommendations of appropriate solid film lubricants. Three original fastener designs were found suitable for the lunar environment. A structural analysis is presented for each original design

Effects of Ambient Gases On ICF Target Capsules

We researched how the chemical and physical properties of a plasma polymer fuel capsule change as they are exposed to ambient gases. The fuel capsules contain the deuterium fuel inside them, they serve as the outer shell for the fuel and act as a ablator for the process. If they are reactive or diffusive with the atmosphere this can change their mass and effect the outcome of the fusion shots performed at the National Ignition Facility where High Powered Lasers are incident upon a gold hohlraum containing a capsule. We discovered that nitrogen and water vapor diffuse into the material but they also desorb with none to little net gain in mass, oxygen as we suspected is more reactive and adds to the mass of the polymer irreversibly

Understanding and Efficiently Managing Right-to-Take Challenges in Kentucky

Executive Summary Kentucky constitutional and statutory law requires that a fair process be in place to let a property owner challenge a condemnor’s right to acquire private property, including a right to appeal the initial decision. Property acquired by a condemnor must be for public use, and property owners have the right to an immediate and expedited hearing on right-to-take. Two of these requirements will remain in place regardless of statutory revisions: the requirement that property must be needed (i.e., not arbitrary) for public use, and the right to one appeal. Only an amendment(s) to the Kentucky Constitution would alter these requirements. The right to an expedited hearing is granted by statute and subject to statutory revisions. Most condemnation practitioners perceive the frequency of right-to-take challenges as holding steady, while other see them as increasing. Attorneys report that most property owners make right-to-take challenges because they perceive the condemnor’s offer of just compensation as unfair. Attorneys also observe that property owners sometimes leverage challenges as a delay tactic or to minimize a project’s impact on their property. Kentucky has what the legal community considers a quick take approach to eminent domain, which means that the right to access and use property is obtained before a final determination is made on compensation. While a property owner is free to make right-to-take challenge or appeal an unsatisfactory decision of a challenge, Kentucky’s Eminent Domain Act and legal precedents require expedited trials and appeals of this issue. Additionally, condemnation practitioners currently have tools at their disposal to help prevent a challenge or overcome delays in resolving a challenge. A range of solutions are available to improve the right-to-take process. For example, before identifying a parcel as requiring condemnation, preventative measures can be taken during right-of-way negotiations and must be implemented with Division of Right of Way agents working more closely with attorneys prior to. Other solutions can be adopted through more efficient record keeping during a roadway project’s planning and acquisition phases. Attorneys litigating these cases can leverage a number of legal tools, including the use of an Agreed Interlocutory Order and Judgment; dismissing suits and refiling them after a perceived deficiency has been corrected; a more informed understanding of stays with a selective use of supersedeas bonds, and Civil Rule 11 sanctions (imposition of attorney fees). Early right of entry agreements are also available. One strategy not fully available in Kentucky is a statutory requirement holding that the losing party pay attorney fees if a challenge is made. A condemnor can request — and has been awarded — attorney’s fees after a successful defense of a right-to-take challenge. However, the award is discretionary and will only be granted in the face of egregious conduct. Compared to other states, Kentucky employs similar resolution methods (e.g., monetary settlements, plan changes). And its performance in resolving right-to-take challenges equals that of other states

Light is Loud A Sound Driven LED Suit

We approach performance as fundamentally a hybrid situ- ation: that performer and technology are united in a post- phenomenological embrace. Light is Loud takes this as a starting point: the form of the performer is subsumed into an array of lights that takes the temporal shape of a self- referential text. The loss of the human form in the piece be- comes a critical statement on the ambiguity of hybridity. In a completely darkened space, a figure with some strips of LEDs speaks a short poem overtly on the nature of “loud”. While the title of the piece, Light is Loud, suggests “daz- zling”, the effect is a meditation on the nature of quiet.

Field observations of swash zone infragravity motions and beach cusp evolution

The definitive version was published in Journal of Geophysical Research 110 (2005): C02018, doi:10.1029/2004JC002485.Fluid flows consistent with low-mode edge waves were evident in video observations of swash motions during a field experiment in which beach cusps developed on an initially smooth beach. As beach cusps grew, energy lying along low-mode dispersion curves increased. The most energetic edge-wave propagation direction changed from upcoast to downcoast as the orientation of the cusp horns rotated. These observations suggest a coupling between morphodynamics and hydrodynamics, and are evidence that beach cusp evolution might control low-mode edge wave dynamics.This work was performed while Y.

STB-White

The final design of a hypersonic, SCRAMjet research aircraft, which is to be dropped from a carrier plane, is considered. Topics such as propulsion systems, aerodynamics, component weight analysis, and aircraft design with waverider analyses are stressed with smaller emphasis placed on aircraft systems such as cockpit design and landing gear configurations. Propulsion systems include analysis of the turbofanramjet for acceleration to low hypersonic speed (Mach 6.0) and analysis of the SCRAMjets themselves to carry the aircraft to Mach 10.0. Both analyses include the use of liquid hydrogen as fuel. Inlet design for both propulsion systems is analyzed as well. Aerodynamic properties are found using empirical and theoretical formulas for lift and drag on delta-wing aircraft. The aircraft design involves the integration of all preliminary studies into a modified waverider configuration
