Eph-Ephrin Signaling and the Role of EFN-4 in Caenorhabditis Elegans Nervous Systems Development
… <em>Caenorhabditis elegans </em>ephrin-A, <em>efn-4</em>, has a defined role in hypodermal patterning but its role in nervous system development is not well understood. We find that loss-of-function mutations in <em>efn-4</em> lead to suppression of axon branching in <em>C. elegans</em> model …

Quantitative photoluminescence studies in a-Si:H/c-Si solar cells
… in terms of splitting of quasi-Fermi levels EFn-EFp derived from PL, which gives the maximum achievable Voc. Effective lifetime Tau eff,pl and its intensity dependence are also calculated. Using the advantage of PL as a contactless method, consecutively processed layers during device …

Investigating the role of ephrins and their receptors in mouse folliculogenesis and ovulation
… hormone (LH) that triggers ovulation. Ephrins (Efn genes) and Eph receptors (Eph genes) are membrane-associated signaling molecules that mediate communication at sites of cell-cell contact, and have been extensively studied in the context of embryonic development. The published literature …

"A Community of People Worthy of the Name Community": The Engagement Practices, Wellness, and Self-Identity of Anishinaabe Young Women and Young Two-Spirit People of Eabametoong First Nation
… people living in Eabametoong First Nation (EFN). Guided by Community-Based Participatory Research and Indigenous Research Methodologies, I collaborated with contributors from EFN to understand the way engagement, well-being, and self-identity are interconnected. The contributors with whom I …

Ephrin Receptors, AIY Interneuron Physiology, and Behavior
… ventral AIYL/R contact. Conversely, the ephrin EFN-4 is required for dorsal AIYL/R connectivity. We have extended these studies and show that the AIYL/R ventral contact is mediated via the ephrin gene <em>efn-1</em>. In addition, we show that this connectivity requires both VAB-1 kinase activity …

Transcriptional Regulation of kal-1 in the Nematode Caenorhabditis elegans
… synergistic lethality with mutations in the <em>efn-4</em> gene, similar to those seen in <em>kal-1</em>, although they did not obviously affect neuroblast migration and gastrulation cleft duration. To identify additional regulatory targets of <em>cnd-1</em>, we performed a comparative …

Electron disintegration of helium between 45 and 100 MeV
The differential cross section of 4He(e,efn)3He:,was measured at five angles over an energy range of 45-100 MeV. Electrons from the National Bureau of Standards 120 MeV, 40 kW linear electron accelerator struck a gaseous-He target. The charged reaction products were detected by 10 lithium drifted …

High valent element fluorosulfates and fluoride- fluorosulfates
… nonstoichiometric materials of the type EFn(SO3F)5_„ (E = As, I) and BrFn(SO3F)3_,i;the nonstoichiometric property of these compounds has not been previously recognized. The oxidation of molybdenum pentafluoride (MoF5) by either S206F2 or FOSO2F produced MoOF3(SO3F) in addition to MoF6 …

The Comparative Anatomy of Extrafloral Nectaries in the Cactus Family (Cactaceae)
Extrafloral nectaries (EFNs) are specialized glands that unlike floral nectaries, which function primarily in pollination, are typically associated with plant defense, attracting invertebrates whose presence and activity can reduce herbivory. EFNs were first observed in cacti in 1837 and have been …

Incentives and Barriers to Participation in Community Nutrition Education Programs for Recipients of Food Stamps and Temporary Assistance to Needy Families
… Expanded Food and Nutrition Education Program (EFNEP) and the Food Stamp Nutrition Education (FSNE) program. This qualitative study sought to hear the voices of the women so that nutrition programs can be made more successful in reaching this population. Personal interviews were conducted with …
