Antioxidant activities of sliver carp scale collagen peptides -SCSCP- were investigated. SCSCP was separated by ultrafiltration using the Omega membranes with molecular weights cut-off of 5, 3, and 1ku. Antioxidant activities of ultrafiltration fractions were evaluated using six in vitro methods. The results showed th…
The antimicrobial activities, free radical scavenging capacity, the content of total phenols, and total flavonoids of primary and secondary distilled bamboo vinegar were investigated. In addition, the primary and secondary distillation bamboo vinegar was analyzed for the main bioactive compounds by HPLC. The results i…
We analyze the polarization-preserving property of two conventional edge-lit light guide plates (LGPs) based on scattering dots and refractive microgrooves and find that these two structures almost completely depolarize the incident linearly polarized light. We then propose a new edge-lit LGP based on total internal r…
日本産生糸とイタリア産生糸は、蚕品種・セリシン含有量の多寡に基づいて生糸市場で住み分けを行っていた。従って、日本産生糸が経糸として使われなくなるという事態は起きなかった。しかし、日本がセリシン含有量の多い生糸を生産するようになると住み分けが崩れた。
La siguiente propuesta busca seleccionar o modificar un ensayo fundamental de caracterización por deformación permanente en mezclas asfálticas, que pueda ser implementado en el LanammeUCR. Inicialmente se consideran los ensayos confinados de barrido de esfuerzos no destructivos y los ensayos barridos de esfuerzos a di…
In this study the effects of the cutting-tool coating material and cutting speed on the cutting forces and surface roughness were determined using the Taguchi experimental design. For this purpose, the nickel-based superalloy Hastelloy X was machined under dry cutting conditions with three different cemented-carbide t…
A newly designed Vacuum Coating System (VCS) system has been used for the first time to prepare magnetic iron thin films on plastic kapton and rigid glass substrates at different rotation speeds (0 rpm, 30 rpm, 60 rpm, and 90 rpm). The powdered iron as a source material was evaporated by a resistively heated furnace p…
Magnesium and its alloys are widely used in many industrial applications because of their high specific strength (strength/density) ratio. However, these applications are still restricted by the relatively poor surface resistance of these materials. To overcome the inherent drawbacks a useful solution is to deposit a…

Jami Mosque of Yazd is one of the great and important mosques of Azari style in Iran. We can imply to the features of this building such as high facade, long minarets, beautiful tiling, dome & etc. The utilization of designs in plaster cast, beautiful designs and tiling are very important and interpretable. The combin…
One of the effective ways to improve properties of cellulosic material is modifying it by using enzyme and substance has molecular structure similar to cellulose like chitosan. In our study cotton fabric Giza 70 and blended fabric cotton with polyester ratio (65:35). Were used treated fabrics by two concentrations 0.1…
Iranian rural carpets are major sources for the study of Iranian rural art and culture. Applications of motifs and colors of these carpets reflect the culture, customs, art and lived experience of the local people. The presence of common aspects in frames of Kheshti rugs and their colors, indicate the presiding spirit…
Safavid pottery, like the other arts in this period has experienced considerable growth and dynamism. In this period masterpieces of pottery, from lusterware and “blue and white" to the Celadon and Kubachi and Gombroon have been produced in numerous centers of pottery. Many ceramics from Kerman and Mashhad have surviv…
[[abstract]]本研究主要在探討不同規格的聚乳酸(PLA)之物理及熱性質，並選用出適當的聚乳酸原料，經熔融紡絲製成POY 纖維，量測其在不同參數設定下之伸度與強度等，再依據參數的設定，假撚成DTY 纖維，並且對紡製而成的DTY 纖維做初步的探討，以建立適用於紡絲及紡織之聚乳酸原料技術與完整的聚乳酸紡絲及紡織品最佳化製程之加工參數，促進聚乳酸纖維材料的應用層面。由結果中得知PLA 6201D 為最合適之原料，在紡絲速度為3000m/min 之POY 纖維之纖維品質較佳。又以假撚機之加工速度為600m/min 及延伸率為1.45 者可得出較佳的強度及伸度的DTY 纖維。因此DTY 纖維的假撚機參數設定中延伸比的設定對於DTY…
[[abstract]]鎂合金因其質輕和價格低廉等特性，在各個產業中的使用量日益增加，但因其不耐腐蝕，限制許多作用，所以使用微弧氧化技術作表面處理，又在市場的需求下，外觀也日益受到重視。本實驗使用微弧氧化後的AZ31 鎂合金板材，使用反應性染料成功對其進行染色，但其耐日光牢度差，無法達到工業上照射200 小時的要求。本實驗用不同染色條件探討其耐日光牢度，然後進行耐日光改善處理，由實驗結果顯示在pH12 溫度70℃濃度3%下塗佈後可從50 小時提升到200 小時，且有最佳△E 值為4.06，為改善耐日光最佳的條件。 Features such as lightweight and inexpensive of magnesium,…
[[abstract]]The central task of this research is devoted to the measurement of the solubility of two antioxidants-D-isoascorbic acid and calcium L-ascorbate dihydrate-in supercritical carbon dioxide. The experiment, using a semiflow type apparatus, takes data at various temperatures, over pressures ranging from 12 MPa…
[[abstract]]本研究設計ㄧ新穎的多紡口電紡結構，搭配近場靜電紡絲製程技術(Near-field Electrospinning)，達到同時電紡多根PVDF 纖維的目標，再導入玻璃滾筒式收集方式，製作出批量綑狀且高機能的聚偏氟乙烯(Polyvinylidene fluoride, PVDF)壓電纖維。製程中，藉由定量注射幫浦的輔助，使PVDF 溶液裝填於以印刷電路板(Printed circuit board, PCB)與錫球結構製作的多紡口系統結構中，施予1.0*107 至1.6*107V/m的環境電場，使PVDF液滴而形成泰勒錐狀(Taylor cone)，其突破表面張力形成極細的PVDF壓電纖維，並批量收集於滾動中的…
Tendon injuries are often associated with significant dysfunction and disability due to tendinous tissue’s very limited self-repair capacity and propensity for scar formation. Dental-derived mesenchymal stem cells (MSCs) in combination with appropriate scaffold material present an alternative therapeutic option for te…
Se interpreta el rol histórico e ideológico de la matriz epistémica que rige el origen, regularidades y formas culturales de conocer para comprender, que la verdad del conocimiento se soporta en el episteme.
Economic growth has traditionally been linked to road freight transport demand, leading to a steady rise in social and environmental impacts. Concern about this problem has caused the EU to promote a decoupling strategy aimed at boosting sustainable development in European countries by improving the efficiency of tran…
