为了充分利用城市固体废弃物中的各项资源,本项工作将固体废弃物中的高密度聚乙烯(H igh dens itypo lyethy lene,HDPE)回收后与废弃的木纤维进行复合,成功地制备出再生型木塑复合材料。研究了木纤维长度、含量以及相容剂对木塑复合材料热性能和力学性能的影响。通过扫描电子显微镜观察了复合材料的冲击断口形貌,分析了此类复合材料的断裂机制。结果表明:木纤维的加入使HDPE的结晶温度降低,结晶速度减慢;相容剂的加入大大改善了木纤维与基体树脂之间的界面结合。随着木纤维含量的增加,木塑复合材料的弯曲强度升高,冲击强度下降。

Investigation of Crystallization and Microstructure of Na2O-CaO-P2O5-SiO2-Al2O3Bio Glass Ceramic System

引用

New Journal of Glass and Ceramics 2012年第1期2卷 1-6页

作者： bahman Mirhadia Behzad Mehdikhanib 不详

The effects of Al2O3 on the crystallization behavior of glass compositions in the Na2O-CaO-P2O5-SiO2 system were investigated by differential thermal analysis (DTA), X-ray diffraction (XRD) and scanning electron microscopy (SEM). In this system, thermal parameters of glasses were studied by DTA. The density of the glass ceramic samples was measured by Archimedes’ method. It was found that the glass-ceramic containing 2.0 molar percent Al2O3 had desirable sintering behavior and reached to an acceptable density. Phase investigation and micro structural study were performed by XRD and SEM, respectively.

On the Performance of Blind Chip Rate Estimation in Multi-Rate CDMA Transmissions Using Multi-Rate Sampling in Slow Flat Fading Channels

引用

Wireless Sensor Network 2009年第2期1卷 69-75页

作者： Siavash GHAVAMI bahman ABOLHASSANI School of Electrical Engineering Iran University of Science and Technology Tehran Iran

This paper considers blind chip rate estimation of DS-SS signals in multi-rate and multi-user DS-CDMA systems over channels having slow flat Rayleigh fading plus additive white Gaussian noise. Channel impulse response is estimated by a subspace method, and then the chip rate of each signal is estimated using zero crossing of estimated differential channel impulse response. For chip rate estimation of each user, an algorithm which uses weighted zero-crossing ratio is proposed. Maximum value of the weighted zero crossing ratio takes place in the Nyquist rate sampling frequency, which equals to the twice of the chip rate. Furthermore, bit time of each user is estimated using fluctuations of autocorrelation estimators. Since code length of each user can be obtained using bit time and chip time ratio. Fading channels reduce reliability factor of the proposed algo-rithm. To overcome this problem, a receiver with multiple antennas is proposed, and the reliability factor of the proposed algorithm is analyzed over both spatially correlated and independent fading channels.

There has been a progressively rivalry among different cities for attaining development opportunities and attraction of economic and social capitals in the recent years. In this universal rivalry, the quality of spaces and urban design are considered as key factors for evaluating cities. Therefore, in this research in order to comprehend the spatial deficiency of the public welfare services in different regions of Ahwaz city, issues such as land uses in different parts of the city, the state and per capita of land uses in the city and comparison of the current land uses with per capita of Comprehensive Plan approved in 1988 are analyzed. Also, evaluation and comparison of the land uses distribution state in different parts of Ahwaz in form of different regions of the city, population distribution in those regions, residential spaces distribution in the regions, commercial spaces distribution in the regions, educational spaces distribution in the regions, religious, sanitary and therapeutic, athletic, administrative spaces, green spaces and other spaces distribution in the different regions are also evaluated in this research.

In this article we are going to introduce the neural network approach to approximate the solution for optimization problems. Using this approach we are able to approximate the optimum values for the large class of functions in particular giving the prices of different products that are resulted from refining the crude petroleum into different substances. We are going to design a neural network that can provide us with a decomposition of the given crude petroleum into resulted products in such a way that is most beneficial for the refinery.

Oligonucleotide delivery by chitosan-functionalized porous silicon nanoparticles

Nano Research 2015年第6期8卷 2033-2046页

Porous silicon nanoparficles （pSiNPs） are a promising nanocarrier system for drug delivery owing to their biocompatibility, biodegradability, and non-inflammatory nature. Here, we investigate the fabrication and characterization of thermally hydrocarbonized pSiNPs （THCpSiNPs） and chitosan-coated THCpSiNPs for therapeutic oligonucleotide delivery. Chitosan coating after oligonucleotide loading significantly improves sustained oligonucleotide release and suppresses burst release effects. Moreover, cellular uptake, endocytosis, and cytotoxicity of oligonucleotide-loaded THCpSiNPs have been evaluated in vitro. Standard cell viability assays demonstrate that cells incubated with the NPs at a concentration of 0.1 mg/mL are 95% viable. In addition, chitosan coating significantly enhances the uptake of oligonucleotide-loaded THCpSiNPs across the cell membrane. Moreover, histopathological analysis of liver, kidney, spleen, and skin tissue collected from mice receiving NPs further demonstrates the biocompatible and non-inflammatory properties of the NPs as a gene delivery vehicle for intravenous and subcutaneous administration in vivo. Taken together, these results suggest that THCpSiNPs provide a versatile platform that could be used as efficient vehicles for the intracellular delivery of oligonucleotides for gene therapy.

将固体废弃物中的高密度聚乙烯(HDPE)回收后与废弃的木纤维以及短切玻璃纤维进行复合,成功地制备出混杂型木塑复合材料。研究结果表明,采用长径比较大的L型玻璃纤维增强时,木塑复合材料的弯曲强度、弯曲模量以及冲击强度同时得到提高,而采用长径比较小的玻璃纤维增强时,弯曲性能和冲击强度均呈现下降趋势。玻璃纤维增强木塑复合材料的主要破坏模式为玻璃纤维的拔出、玻璃纤维断裂、界面脱粘等。在玻璃纤维/木纤维/HDPE混杂体系中由于组元之间的协同增强作用,形成了特殊的三维网络结构,木塑复合材料的力学性能得到显著改善。
