This study investigated the influence of ZnO nanostructures on dye adsorption to increase the photovoltaic conversion efficiency of solar cells. ZnO nanostructures were grown in both tree-like and nanorod (NR) arrays on an AZO/FTO film structure by using a hydrothermal method. The results were observed in detail using X-ray diffraction, field-emission scanning electron microscopy (FE-SEM), UV-v...

The limited jetty capacity of ports causes costly ship delays, particularly for large ocean-going vessels. Terminal operators attempt to reduce ship delays both in number and duration but have to take the number of jetties and their functionality and layout as a fact. Ships can arrive according to a schedule, for example based on stock levels, or unscheduled, or even uncontrolled which is the c...

The characteristics of restaurant wastewater were investigated. High oil and grease contents were detected. Electrocoagulation was used to treat this type of wastewater. Different electrode materials and operational conditions were examined. Aluminum was preferred to iron. Charge loading was found to be the only variable that affected the treatment efficiency significantly. The optimum charge l...

The current financial crisis seems to be seriously affecting the freight transport system. In this scenario, transport terminals play a crucial role to avert the risk of recession by increasing their efficiency and automation. Only in this way is it possible both to reduce the price of the services offered (loading, unloading, dwelling, logistic services ...) and increase terminal earnings. In ...

Transferrin (Tf) was immobilized onto Fe3O4@SiO2 nanoparticles with high doxorubicin (DOX) loading (TfDMP), for dual targeting of cancer, by chemically coupling both Tf and DOX with dual-function magnetic nanoparticles (DMPs) using a multi-armed crosslinker, poly-L-glutamic acid. With high trapping efficiency for magnetic targeting, TfDMP exhibits a Tf receptor-targeting function. Moreover, the...

Start sites of DNA replication are marked by the origin recognition complex (ORC), which coordinates Mcm2-7 helicase loading to form the prereplicative complex (pre-RC). Although pre-RC assembly is well characterized in vitro, the process is poorly understood within the local chromatin environment surrounding replication origins. To reveal how the chromatin architecture modulates origin selecti...

In this paper, drug–loaded chitosan microspheres were prepared by spray drying technique, using glutaraldehyde as cross–linking agent and salicylic acid as model drug. Effects of formulation and process parameters on the morphology of chitosan microspheres were investigated. The drug loading and encapsulation efficiency were determined. In vitro release of the drug into phosphate buffer at 37 °...

introduction water is consumed in almost all industries. consequently the used water is turning to a waste that usually should be treated to meet the regulated standard level prior to reuse or discharge into the environment. cutting oil wastewater is an emulsion normally comprised of1-10% oil and the remainder water. the main functions of this oil in industry are lubrication, friction reduction...

Analysis of the laminated composite plates under transverse loading is considered using the new method of Isogeometric Analysis (IGA). Non-Uniform Rational B-Splines(NURBS)are used as shape functions for modeling the geometry of the structure and also are used as shape functions in the analysis process. To show robustness of the new technique, some examples are represented and are compared with...
