La Cultura Profesional De Los Docentes En Enseñanza Secundaria: Un Estudio Biográfico, José Ignacio Rivas Flores, Maria Del Pilar Sepúlveda Ruíz, Pilar Rodrigo Muñoz

Education Policy Analysis Archives (EPAA)

This work discusses the "voices" of teachers working "at the chalk face". We are interested in learning what teachers think and behave. Therefore, we conducted our research about their working conditions. We also developed teachers’ professional biographies to learn how these educators construct concepts and practices related to their profession and what constitutes their "professional culture". We understand that the professional culture characterizes teachers’ professional frameworks and choices; therefore, any attempt to successfully promote an educational reform, must understand and pay attention to the “professional culture”

Study Of Partial Discharge Activity In Magnet Wires Aged By Combined Stresses, Ashwini Mani

Theses and Dissertations

Partial discharge testing is a nondestructive method of identifying possible premature insulation breakdown. Magnet wires are used in various electrical equipment like injection coils, solenoids, small transformers and motors. Winding wires used in high voltage systems are subjected to several stresses during operation, which considerably lowers their lifetime. A prolonged combined effect of these stresses causes aging of the wires, inception of partial discharge activity, and degradation of the organic material in the enamel coating and varnish used by the manufacturer. The tests were conducted for AWG 30 and AWG 31 twisted magnet wire samples. The samples are aged under …

Identification And Location Of Sunken Logs Using Sidescan Sonar Technology, Aravindh Srivatsav Ravichandran

Theses and Dissertations

Identifying the location of sunken logs is a task of considerable interest in today?s world economy. The main motive of this work is to find and locate sunken cypress logs that were lost during the transit to a lumber mills. Underwater logging is possible because of the fact that many of the logs were barely affected by the decades of submersion. Cypress logs, the types of logs used in this research have a natural resistant to rotting. The other probability for the logs not being affected significantly, even staying in water for decades, is the high density of the growth …

Evaluation Of Chitosan Gelatin Complex Scaffolds For Articular Cartilage Tissue Engineering, Harshal Prabhakar Mahajan

Theses and Dissertations

In search of better scaffolding materials for in vitro culture of chondrocytes, the combination of chitosan (similar to glycosoaminoglycans) and gelatin (denatured collagen) was tested due to its resemblance to cartilage extra-cellular matrix (ECM). Porous scaffolds were fabricated from chitosan gelatin blends (1:1, 2:1, and 3:1). The response of chondrocytes to them was evaluated from the amount of sulphated GAG and collagen type 2 secreted after 3 and 5 weeks. The effect due to static (transwell inserts) and dynamic (rotating bioreactor) culture methods was analyzed. Results indicate that 1:1 chitosan gelatin blends showed the best chondro-conductive potential. The rotating bioreactor …

With the explosive deployment of wireless LAN technology in the past few years and increasing demand on multimedia applications, the efficient utilization of the precious wireless radio link resources and support of Quality of Service (QoS) in WLANs has become a prominent research issue. In this thesis, an adaptive p-persistent based I 802.11 MAC scheme in WLANs has been proposed. The proposed scheme can maximize the total channel throughput, and also provide service differentiation among multiple traffic classes. This is achieved by updating the transmission probabilities for the stations that compete for transmissions in a WLAN, adaptively based on the …

Fatigue Crack Growth Under Residual Stresses Around Holes, Ramesh Nagaralu

Theses and Dissertations

Compressive residual stresses induced by tensile overloads, compressive under loads, or by a cold-expansion process in specimens containing a circular hole and their influence on subsequent fatigue crack growth in aluminum alloys are studied. The finite element method is used to calculate residual stresses. The superposition method, which uses crack-tip stress intensity factors for cases involving remote loading and residual stresses, is used to calculate crack growth life for three kinds of tests from the literature: (1) fatigue of a circular hole specimen after an overload or under load, (2) single crack growing from a circular hole after a severe …

Biomechanical And Metabolic Changes Within Rabbit Articular Cartilage Following Treatment With Radiofrequency Energy, Christopher Larry Horstman

Theses and Dissertations

The effects caused to articular cartilage by the remote use of arthroscopically-delivered RF energy to soft tissues in the joint are unknown. This investigation reported the short and long-term effects of bRF and mRF energy on the biomechanical properties and metabolic activity of articular cartilage. In addition, the effect of Cosequin® therapy was addressed. Thirty New Zealand white rabbits were randomly assigned to one of two treatment groups (Group 1 - placebo; Group 2 - Cosequin®). Histopathology, cell viability, GAG synthesis, and mechanical function of the articular cartilage were compared between groups. Data were analyzed using a mixed model ANOVA …

A Consideration Of Church Planting Through Radio Broadcasting In Thailand, Byung Jo Chang

The research focuses on founding and organizing the broadcasting station in the hopes of giving non Christians opportunities to hear the gospel for the first time, and helping them to become Chris like.

The potential radio broadcasting missions carry, the meaning of it all, and the efficiency behind planting a church through the broadcasting missions is examined. These …

Cyanate Ester, Epoxy And Epoxy/Cyanate Ester Matrix Polyhedral Oligomeric Silsesquioxane Nanocomposites, Kaiwen Liang

Theses and Dissertations

Cyanate ester (PT-15, Lonza Corp) composites containing the inorganic-organic hybrid polyhedral oligomeric silsesquioxanes (POSS), octaaminophenyl(T8)POSS (C6H4NH2)8(SiO1.5)8, cyanopropylheptacyclopentyl(T8)POSS, (C5H9)7(SiO1.5)8(CH2) 3CN or TriSilanolPhenylPOSS (C42H38O12Si7), were synthesized respectively. These PT-15/POSS composites were characterized by FT-IR, X-ray diffraction (XRD), small-angle neutron scattering (SANS), scanning electron microscopy (SEM), X-ray energy dispersive spectroscopy (X-EDS), transmission electron microscopy (TEM), dynamic mechanical thermal analysis (DMTA) and three-point bending flexural tests. XRD, TEM and IR data are all consistent with molecular dispersion of octaaminophenyl(T8)POSS and TriSilanolPhenylPOSS due to the chemical bonding of the POSS macromer into the continuous cyanate ester network phase. In contrast to octaaminophenyl(T8) POSS and TriSilanolPhenylPOSS, …

The Geology And Hydrology Of The Proposed Upper Mccurtain Creek Watershed Impoundment Choctaw County, Mississippi, Leonard D (Leonard Dwight) Rawlings

Theses and Dissertations

The McCurtain Creek watershed was proposed for a large reservoir project resulting in the commissioning of this study to assess the site?s geology, hydrogeology, and surface hydrology to find whether or not the site was suitable. Data was collected from 57 geophysical logs from coal exploration boreholes to produce geologic and aquifer cross sections. A program to assess discharge identified surface hydrology characteristics of the stream at five locations. Twenty-seven geotechnical boreholes, 23 standpipe piezometers, and the data from the coal exploration were used to map the water table using ArcGIS 8.3 software. Eighteen piezometers at stream sites, used to …

Screening Soybean Genotypes For High Temperature Tolerance By In Vitro Pollen Germination, Pollen Tube Length And Physiological Techniques, Mohammed A. Salem

Theses and Dissertations

We are now witnessing changing environmental conditions and these changes will likely continue into the coming decades due to projected increases in temperatures on the earth surface. Recent model projections suggest that the global mean surface air temperatures will increase by 1.4 to 5.8 °C by 2100. The consequences of these high temperatures include reductions in crop yields. Soybean is one of the major crops grown in the US, where high temperatures (>35 °C) during reproductive growth decreased yield. Two experiments were conducted to determine the effects of temperature on soybean pollen germination properties and identify responses to temperature …

An Investigation Of Firms' Earnings Management Practices Around Product Recalls, Zeeshan Ahmed

Theses and Dissertations

This study investigates the earnings management practices of firms around product recalls. In recent years, the management of earnings around firm-specific events has received considerable attention in the finance and accounting literature. New equity issues, mergers and acquisitions, share repurchases, and management buyouts are some events around which at least some firms have been shown to manage their earnings to achieve managements? objectives. Product recalls offer yet another interesting occasion when managers have incentives to cover up the true financial performance of their firms and mislead investors. In order to determine whether firms announcing product recalls manage earnings more aggressively …

Individualistic Roamers Or Community Builders?:Differences And Boundaries Among Rvers, Gloria Anne Mattingly

Theses and Dissertations

The number of leisure and working RVers roaming America?s highways, now conservatively estimated at over eight million, continues to increase (Curtin 2001; Sommer 2003). In spite of their growing presence and unique lifestyle, these populations remain sociologically understudied. This exploratory case study of two distinctly different RV parks is a small but significant step toward filling that research gap. At both RV parks I found a diverse population of individualists who value self-contained travel, freedom, relaxation, and sociality. In spite of sharing a collective, subcultural lifestyle, they differed along multiple axes. Marked differences separate RVers into three broad groups (full-timers, …
