The paper has conducted a study on the variation of tensile strength for four woven fabrics made from wool type yarns depending on fiber composition, warp and weft yarns tensile strength and technological density using ANCOVA regression model. In instances where surveyed groups may have a known history of responding t…
An investigation was made of the influence of the production equipment on the homogeneity and physicomechanical properties of composites based on polyolefins filled with aluminium trihydrate. The quality of mixing and the degree of dispersion of the components were assessed from the magnitude of the coefficient of var…
The fire safety and physicomechanical properties of three grades of developed composites based on thermoplastic elastomers are given. A method for lowering the flammability of polymers by introducing fireproofing agents is examined.
Work has been carried out to optimise the production of polyamide 6 and layered nanocomposites by anionic polymerisation, during which a layered aluminosilicate is mixed directly with the monomer, catalyst, and activator, and polymerisation of the monomer (oligomer) results in intercalation of the polymer in the inter…
β-nucleant is used in polypropylene homopolymer (h-PP) primarily to improve its toughness as this particular property is important for piping and pipe coating application. In this work, the effect of β-nucleating agent on h-PP as topcoat material for pipe coating was investigated. The distribution of the nucleating ag…
Objectives: Wound healing and angiogenesis are impaired in patients with diabetes and peripheral vascular disease. We developed a novel treatment by systemic administration of mesenchymal stem cells (MSC) coated with nanocarrier composed of adhesion molecule -nanoparticle complex (AMNC). AMNC-MSC significantly enhance…
Cell resourcing remains one of the major problems in the development of patient-specific TEBVs. The iPSC derived cardiovascular cells provide a promising source for TEBVs and cell therapy. The goal of this study is to construct TEBVs using patient-specific iPSCs. Using a non-integrated episomal vector based reprogramm…
Objectives: Molecular imaging enables non-invasive in vivo detection of vulnerable plaques. Last year, we reported an atherosclerosis imaging agent, 111In-labeled liposome. The liposome was modified with phosphatidylserine (PS), since macrophages recognize PS to phagocytize apoptotic cells in the plaque. PS modificati…
GaN is a semiconductor material with great potential for use in high power electronics and optoelectronics due to the high electron mobility, high breakdown voltage, high thermal stability, and large direct bandgap of GaN. Si is a desirable substrate material for GaN heteroepitaxy due to the low cost of production, la…
This article discusses why it is essential to develop new codes and standards for nuclear power industry. The reason for developing new codes for nuclear power sector is simple to understand. It has to do with the fundamental purpose of all standards: Standards exist to serve not only all the stakeholders in an indust…
Front Cover: The framework structure of rigid poly(amide acid) and polyimide networks can be tuned by the selection of a robust and symmetric crosslinker structure. The S4-symmetric four-armed crosslinker can provide homogeneous network structures compared with the C3-symmetric three-armed crosslinker. Further details…
Se elaboraron los especimenes, reproduciendo en cada uno de ellos las temperaturas registradas, a fin de lograr las caracteristicas obtenidas en cada extremo de las barras de acero cortadas con los metodos analizados. Todo esto a fin de que los ensayos realizados representen de la forma mas cercana, los resultados obt…
Cationic gemini surfactants have been used for delivery of DNA into cells. These cationic surfactants are known to strongly bind to DNA to form a complex. In the dilute regimen, when the gemini-DNA complexes are mixed with helper neutral lipids, they undergo spontaneous assembly to form particles that are able to tran…
가스화기 종류는 크게 고정층, 유동층, 분류층으로 나눌 수 있으며 석탄 가스화기 는 주로 분류층을 이용한 대형 가스화시스템 개발에 치중되어 있다. 석탄은 다량의 연료 공급이 용이하므로, chemical 및 합성연료 생산, IGCC와 같이 투자규모가 큰 사업을 대상으로 발전했으며 상용화된 석탄 가스화기는 분류층 방식을 활용하였다. 분류층 가스화기는 석탄을 미분화 하여 이용하고 산소를 가스화제로 사용하므로 수 천 톤/일 이상의 대형 시스템에 적합하며 고온 가스화 과정에서 Ash melting을 동반 하므로 석탄 내 회재 특성에 민감하여 사용 가능한 연료 범위가 비교적…
국민생활 수준의 향상으로 내수시장이 확대되어 현재 우리나라의 자동차 등록대수는 1,950만 여대에 이른다. 이로 인하여 폐자동차의 발생량도 지금까지 일시적인 감소를 제외하고는 꾸준히 증가하여, 2013년에는 77만 여대가 발생하였다. 이중 일부는 중고 차로서 수출되고 대부분은 해체되어 재활용 대상이 된다. 폐자동차의 해체공정을 살펴 보면, 최초 해체업자에게 인도되어 유용 부품이 회수된 후, 압축하여 슈레더 업체로 옮겨지며 이렇게 압축된 차량을 press body라고 한다. Press body에서 철, 비철금속 등의 유가금속을 회수하기 위한 슈레더 공정을 거치고 나면…
The manufacturing process of glass fibers used for the reinforcement of composite material consists in drawing a glass melt at high temperature through an array of thousands of small orifices (i.e. the bushing plate) into fibers using a winder. This process is sensitive to numerous disturbances that can cause the fibe…

Polarization properties of the surface plasmon resonance (SPR) in a nanosized gold film fabricated by the thermal evaporation are studied with the use of the internal reflection method and the modulation polarimetry technique. The spectral and angular characteristics of the reflection coefficients for linearly polariz…
En dispersant correctement des nano-objets dans diverses matrices, on obtient des matériaux composites dont les propriétés offrent de nouvelles opportunités. Cependant, il est indispensable de caractériser les nano-objets au préalable et d'en contrôler la qualité pour garantir la reproductibilité des propriétés visées…
