در این تحقیق نانوسیمهای آلیاژی cocu و nicu درون حفره های قالب پلی کربنات با قطر اسمی 30nm به روش الکتروانباشت تهیه شدند. به منظور رشد نانوسیمهای cocu و nicu به ترتیب از دو الکترولیت مجزای حاوی نمکهای co، cu وni ، cu استفاده شد. برای بررسی رفتار پتانسیودینامیکی الکترولیتها و تعیین ولتاژ بهینه انباشت، منحنی cv مربوط به هر یک از الکترولیتها تهیه و مورد مطالعه قرار گرفت. ساختار نانوسیمها با استفاد...
Guest Editors’ Introduction: at the nexus of mentoring and technology By: WILLIAM A. KEALY AND CAROL
With the ever-increasing role of technology as an innovative force in society, we have witnessed major changes in the types of education being developed and in how learning and instruction is conceptualised. Consider, for example, the dramatic rise in the number of Internet-based courses offered in higher education as well as the evolving role of the teacher as creator of learning environments....
Purpose – The purpose of this paper is to suggest a way to support work-integrated learning for knowledge work, which poses a great challenge for current research and practice. Design/methodology/approach – The authors first suggest a workplace learning context model, which has been derived by analyzing knowledge work and the knowledge sources used by knowledge workers. The authors then focus o...
امروزه کاربرد الکترودهای رسانای شفاف و منعطف نانوسیم های نقره (agnws) به عنوان جایگزینی برای الکترودهای ito در سلول های خورشیدی پلیمری، به شدت مورد توجه قرار گرفته است. در این مطالعه سنتز و روش های کنترل ابعاد agnw ها بررسی شده است. ابتدا agnw ها به روش پلی اُل سنتز شدند. اثر حضور دانه سدیم کلراید به عنوان یک فاکتور کلیدی در تشکیل agnw ها مورد ارزیابی قرارگرفت و هم چنین اثر نسبت پلیمر پلی وینیل ...
Effective conservation of fish species of greatest conservation need (SGCN) requires an understanding of species– habitat relationships and distributional trends. Thus, modeling the distribution of fish species across large spatial scales may be a valuable tool for conservation planning. Our goals were to evaluate the status of 10 fish SGCN in wadeable Iowa streams and to test the effectiveness...
Effective conservation of fish species of greatest conservation need (SGCN) requires an understanding of species-habitat relationships and distributional trends. Thus, modeling the distribution of fish species across large spatial scales may serve as a potentially valuable tool for conservation planning. Our goals were to evaluate the status of 10 Iowa fish SGCN in wadeable Iowa streams and tes...
Vertebrate gap junctions, composed of proteins from the connexin gene family, play critical roles in embryonic development, co-ordinated contraction of excitable cells, tissue homoeostasis, normal cell growth and differentiation. Phosphorylation of connexin43, the most abundant and ubiquitously expressed connexin, has been implicated in the regulation of gap junctional communication at several ...
Background: Although the human genome sequence was declared complete in 2004, the sequence was interrupted by 341 gaps of which 308 lay in an estimated approximately 28 Mb of euchromatin. While these gaps constitute only approximately 1% of the sequence, knowledge of the full complement of human genes and regulatory elements is incomplete without their sequences. Results: We have used a combina...
