A STUDY OF THE RELATIONSHIP BETWEEN TEACHERS' PERCEPTION TOWARDS THEIR LEADERSHIP CAPACITY AND ORGANIZATIONAL COMMITMENT AT KAW DAI NATIONAL SCHOOL IN KARLI, SHAN STATE, MYANMAR

This research study was to determine the relationship between teachers’ perception of their leadership capacity and organizational commitment at Kaw Dai National School in Karli, Shan State, Myanmar. The research instrument was a questionnaire adopted from Lamberts’ (2003) Leadership Capacity School Survey questionnaire and Ismail’s (2012) Survey Questionnaire for Organizational Commitment. The participants were all full-time teachers working in Kaw Dai National School in the academic year 2020 and the responses were analyzed utilizing Descriptive Statistic, Frequency and Percentage, Mean and Standard Deviation, and the Pearson Product-Moment Correlation Coefficient. Based on the study result, it was determined that there was a significant relationship between teachers' perception towards their leadership capacity and their organization commitment at Kaw Dai National School. Additionally, the relationship was interpreted as moderate because the correlation (r)value was .624. Teachers’ quality, leadership capacity, and organizational commitment of teachers are important for student achievement and organizational success. But, at Kaw Dai National School, some aspects of teachers' leadership capacity and organizational commitment were found to be still moderate, so, it was suggested that the school should consider improving them

Area of review: how large is large enough for carbon storage?

The Texas Gulf Coast is an attractive target for carbon storage. Stacked sand-shale layers provide large potential storage volumes and defense-in-depth leakage protection. However, multiple perforations resulting from intensive hydrocarbon exploration and production have weakened seal integrity in many favorable locations. If the ultimate goal of carbon storage is to isolate large volumes of CO2 for hundreds to thousands of years, plume migration will encounter inadequately completed wells miles away from the injection zone. Moreover, the detrimental impact of CO2 on cement could undermine the structural integrity of all contacted wells, although pressure effects subside quickly after injection. Even wells abandoned to current standards cannot be guaranteed leak-free in the long term. We describe spatial statistics extracted from the Texas RRC Well Bore database as applied to carbon storage. Although the Area of Review (AOR) has been traditionally defined by a fixed radius with the strong regulatory requirement that the injectate stays within the injection layer, buoyancy is a major characteristic of CO2 that introduces a third dimension into the Area of Review process. Using simple geological mapping to characterize structural traps, we determine the likely pathway and the contacted volume of a migrating plume. The latter can be as large as a fault compartment with dimensions of 20 km × 20 km. However, the contacted volume is ultimately a function of the total injected volume, and the specifics of each project should dictate the dimensions of the zone of endangering influence (ZEI). An option, viable for the Texas Gulf Coast, to reduce geologic uncertainty, to decrease the impact of wells, and to limit the amount of information to be collected, is to inject CO2 below the maximum penetration of most wells.Bureau of Economic Geolog

An interdisciplinary approach to restore missing maxillary lateral incisor with Orthodontics and Implant Prosthodontics: A Case Report

Abstract The absence of the maxillary lateral incisors create an asthetic problem that can be managed with different treatment modalities. Comprehensive treatment planning is required to achieve a satisfactory result, keeping in mind the aesthetics, function and periodontal stability. An interdisciplinary treatment approach is beneficial and involves orthodontic closure of the space with maxillary canine substitution or space opening for single- tooth implants, bridges and tooth-supported restorations. The present case of a 21-year-old female dental student with agenesis of maxillary left lateral incisor with the presence of maxillary left canine in place of lateral incisor, and midline deviation. Treatment included space creation and placement of 3.3mm implant together with bone augmentation, immediate temporization and finally restored with porcelain crown after healing period of three months

Intelligent Wound Dressing for Therapeutic and Diagnostic Management of Wound Infection

Wound infection is a global problem and approximately 13,000 patients with burns required treatment in hospitals in England and Wales every year. Diagnosis of burn infection is problematic and currently diagnosed by clinical observation and judgement. Standard microbiological culture to identify causative pathogens usually take several days. If pathogens present, this will causes tissue damage by further colonization, extensive infection and formation of difficult-to-treat wound biofilm in wounds which inevitably require aggressive antibiotic treatments. Early indication of infection at point-of-care and ability to rapidly distinguish between infected and non-infected states of wound will help in clinical decision making, prevent over-management by inappropriate use of antibiotics, improve patient outcomes and reduce costs of treatment. Here we have develop an intelligent wound dressing that can detect the infection in wounds. The dressing is made of a hydrated agarose film in which the fluorescent dye containing vesicles were mixed with agarose and dispersed within the hydrogel matrix. The release of dye is triggered by interaction of vesicles with virulence factors, secreted in population-density-dependent fashion via quorum sensing, from pathogenic bacteria. Efficacy of dressing was tested with developed static wound biofilm model using clinical strains of Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus and Enterococcus faecalis. The dressing indicated a clear response when in contact with biofilms produced only by pathogenic strains of bacteria. Colorimetric detection on wound biofilms of prevalent pathogens (S. aureus, P. aeruginosa and E. faecalis) is also demonstrated using an ex-vivo porcine skin model of burn wound infection

Structure of Carbon Nanotubes in Colloidal Solutions under the Influence of a Constant Electric Field

Processes of self-organization in diffusive and limited conditions of colloidal solutions of carbon nanotubes under the influence of constant electric fields are studied. It is established that functionalized MCNT – COOH in a drop of colloidal solution is oriented in an electric field in a controllable way, which is of great practical value
