Frequency response analysis (FRA) is a method of monitoring power transformer’s mechanical integrity. However, identifying the type fault and its severity by comparing measured responses still challenging mostly relies on personnel expertise. This paper taking one step forward to standardize FRA interpretation process proposing guidelines based various international standards case studies. In t...

The Forestry Reclamation Approach uses uncompacted, mounded spoils to reforest mined-land and has been successful in hardwood forests in the Appalachian region. A surface coalmine reclamation site in the Pacific Northwest was used to compare the site’s standard reclamation approach (Reference) with a modified version of the Forestry Reclamation Approach (FRA) along with a modified FRA treatment...

The AP-1 (activator protein-1) complex, which consists of proteins of the Fos and Jun families, is thought to play an important role in the balance between cell proliferation and apoptosis, the response to genotoxic stress and cell transformation. In cells containing oncogenic Ras, the major components of AP-1 are Fra-1 and c-Jun. Signalling from Ras to AP-1 is through the Raf/MEK[mitogen-activ...

Folate receptor alpha (FRA) is a cell surface protein whose aberrant expression in malignant cells has resulted in its pursuit as a therapeutic target and marker for diagnosis of cancer. The development of immune-based reagents that can reproducibly detect FRA from patient tissue processed by varying methods has been difficult due to the complex post-translational structure of the protein where...

Frazzled (Fra) is the DCC-like Netrin receptor in Drosophila that mediates attraction; Roundabout (Robo) is a Slit receptor that mediates repulsion. Both ligands are expressed at the midline; both receptors have related structures and are often expressed by the same neurons. To determine if attraction versus repulsion is a modular function encoded in the cytoplasmic domain of these receptors, w...

MicroRNA-34a (miR-34a), a transcriptional target of p53, is a well-known tumor suppressor gene. Here, we identified Fra-1 as a new target of miR-34a and demonstrated that miR-34a inhibits Fra-1 expression at both protein and messenger RNA levels. In addition, we found that p53 indirectly regulates Fra-1 expression via a miR-34a-dependant manner in colon cancer cells. Overexpression of miR-34a s...

It is asserted that epithelial rests in dental follicle (DF) existing around the impacted teeth in adults are effective in cyst formation. In this study, it is intended for determining and comparing the immunoreactivity (IR) ratio of ATF-2 and Fra-2 proteins, the members of Activator Protein-1 (AP-1) family which regulates important cellular activities such as growth, proliferation and differen...

Epithelial-to-mesenchymal transition (EMT) is a complex biological program occurring in physiological and pathological conditions. The acquisition of a mesenchymal state by cancer cells is associated with loss of epithelial features, decreased cell adhesion and increased migration and invasion, which together are crucial for metastasis. Down-regulation of the adherens junction protein E-cadheri...

An approach based on the nearest neighbors techniques is presented for producing thematic maps of forest cover (forest/non-forest) and total stand volume for the Terai region in southern Nepal. To create the forest cover map, we used a combination of Landsat TM satellite data and visual interpretation data, i.e., a sample grid of visual interpretation plots for which we obtained the land use cl...

Power transformers are key components in electrical power supplies and their failure could cause severe consequences on continuity of service and also generates substantial costs. Identifying problems at an early stage, before catastrophic failure occurs, is a great benefit for reliable operation of power transformers. Frequency Response Analysis (FRA) is a new, well-known and powerful diagnost...
