Motivated by the theoretical calculations that Fe3−xMnxSi can simultaneously exhibit a high spin polarization with a high Curie temperature to be applied in spintronic devices, and in order to further study the effect of Mn contents on the physical properties of Fe3−xMnxSi, we have investigated the effect of Mn substi…
To overcome some drawbacks of optical system for plane and concave grating typed spectrometer, including serious aberration, worse spectral fatness and low diffraction efficiency etc, a novel optical system based on volume phase holographic transmission (VPHT) grating was designed in this paper. For this grating, its…
以聚乙二醇单甲醚作大分子引发剂,异辛酸亚锡作催化剂,将不同比例的e-己内酯（CL）与4-甲基-e-己内酯（MCL）单体开环共聚,并通过控制CL和MCL的投料比以及投料方式,得到了疏水链段上CL和MCL不同比例和分布的4组聚合物.核磁和凝胶渗透色谱法表征了聚合物的结构,示差扫描量热法,广角X射线衍射和红外光谱表征了聚合物的结晶性.采用透析的方法,制备了4种聚合物的纳米胶束,以及载药（阿霉素DOX）胶束,并研究了胶束的自组装行为以及对阿霉素的包裹和释放情况.结果表明MCL单体的引入降低了聚合物的结晶性,提高了对DOX的载药量,加快了DOX的释放.通过激光共聚焦显微镜和流式细胞仪研究了Hep G2肝癌细胞对不同内核结构载药胶束的内吞情况…
Foram investigadas propriedades físicas (densidade de massa aparente; absorção de água) e mecânicas (resistência à compressão e à tração na flexão; módulo de elasticidade) de materiais compósitos com matriz de papel usado reforçado com pó de serragem e de gesso. Os ensaios foram realizados conforme normas brasileira e…

One of the most difficult tasks in estimating any project is to capture all of the costs involved in the project. Every cost estimate requires three basic components. The first is the establishment of standard units of measure. The second component of an estimate is the determination of the quantity of units for each…
Inverse photoelectron spectroscopy (IPES) has been implemented at the University of Massachusetts Lowell through this ARO-funded DURIP award.The instrumentation consists of a low energy electron gun and a photon detector installed in an ultrahigh vacuum (UHV) chamber.When impinging electrons land in unoccupied electro…

Studies dealing with urgent clinical therapy, are described in this chapter with regard to the action of stem cells. Cell therapy – as a basal treatment of myocardial cell loss – has the fundamental aim to prevent or to reverse remodelling by reconstitution of damaged tissue and/or of perfusion, thereby leading to myo…
A finite element model of fibre metal laminate (FML) fuselage was developed in order to evaluate its impact response under survivable crash event. To create a reliable crash finite element (FE) model of FML fuselage, a ?building block approach? is adapted. It involves a series of validation and verification tasks in o…
Glycolic acid is being studied as a total or partial replacement for formic acid in the Defense Waste Processing Facility (DWPF) feed preparation process.After implementation, the recycle stream from DWPF back to the high-level waste tank farm will contain soluble sodium glycolate.Most of the potential impacts of glyc…
In this work we establish the well-posedness for infinitesimal dislocation\nbased gradient viscoplasticity with isotropic hardening for general gradient\nmonotone plastic flows. We assume an additive split of the displacement\ngradient into non-symmetric elastic distortion and non-symmetric plastic\ndistortion. The th…

The Peruíbe Black mud is used in therapeutic treatments such as psoriasis, peripheral dermatitis, acne and seborrhoea, as well as in the treatment of myalgia, arthritis, rheumatism and non-articular processes.Likewise other medicinal clays, it may not be free from possible adverse health effects due to possible hazard…
More and more attention has been paid to the research on phytoremediation and hyperaccumulators. Arsenic (As) uptake by hyperaccumulator plant species depends on many different environmental factors. Fertilizer is one of the most important factors because the plant growth needs nutrients. In this study, the pot experi…
This article presents nano composite TiO2.Fe2O3/laterite materials, which were successfully prepared by hydrometallurgical method. The materials were modified using urea as the nitrogen source. The particles size of the materials is from 20-30 nanometers. The obtained materials can not only absorb arsenic compounds bu…
The sorption of nonionic surfactants (polyoxyethylated nonylphenols with different numbers of oxyethyl groups (NF-12, NF-100)), on a potassium polytitanate surface is studied under different conditions of sorption, concentrations of modifier, and acidities of suspension. Quantitative characteristics of sorption are ca…
Stir casting technique is a conventional and cheap method for the fabrication of Metal Matrix Composites (MMCs). In the present research, Al-6063 as matrix material and fly ash as particulate reinforcement was fabricated with the help of stir casting technique to produce low cost AMC. In this work, the effect of heigh…
A theoretical model is presented to predict effective thermal conductivity of real two phase materials from the values of thermal conductivity of the constituent phases and their volume fraction. Here we develop a numerical expression for effective thermal conductivity of Cu-solder system in two phase system is being…
The attractive application potentials of graphene demand highly efficient, lowcost, and large-scale preparation of this novel carbon material. Therefore, controllable synthesis of graphene has become one of the major tasks in graphene-related research. Since the first successful preparation of single-layer graphene, u…
