Direct functionalization strategy has been employed to modify the surface of the magnetic hollow spheres with (3-Aminopropyl)triethoxysilane (APTES) for targeted drug delivery. Magnetic hollow spheres were characterized by XRD, BET, FE-SEM, VSM and FT-IR. Model drug camptothecin (CPT) has been used to evaluate drug loading and in vitro release.
A pure and ZnO added CdO thin films are prepared by chemical bath deposition to study their ethanol sensing properties. The depositions were carried out in a highly alkaline condition where in cadmium acetate was used as a source of cadmium while zinc acetate was added as the source of Zn inclusion. These films were subsequently annealed at 723K and studied for its morphological, optical and gas sensing...
Human iris provides a unique structure suitable for non-invasive biometric assessment. The irises are as distinct as fingerprints even for twins. In this paper a robust system for person identification is presented that uses a technique of localization, alignment, feature extraction, and matching the features of irises. A CASIA iris database has been used to observe the performance of the proposed...
The basic requirement for studying starting analysis of Induction motor are the starting current of Induction motor and the voltage flicker during start up. This paper will summarize several common methods and provide application guidelines for proper selection of starting devices. Starting method reviewed will include different types of starters, comparative study of results obtained in laboratory...
Full adders are important components in applications such as digital signal processors (DSP) architectures and microprocessors. In addition to its main task, which is adding two numbers, it participates in many other useful operations such as subtraction, multiplication, division, address calculation, ..Etc. In this paper we have presented study of different logic structure using 1-bit full adder...
Recently, several experimental systems based on programmable logic have been designed and implemented which are programmed using a hardware design methodology. One necessary component of the software environment will be a library of standard macrocells corresponding to commonly used arithmetic and logical operations. In this paper Array multiplier is designed specially for programmable logic. This...
