Nanoparticles possess unique properties, which can be applied in medical applications; they address targets such as cellular therapy, tissue repair, Nano-biosensors, drug delivery, magnetic resonance imaging and magnetic fluid hyperthermia. In this work, different sized cobalt ferrite nanoparticles (CFNP) were synthesized with narrow size distribution, by using chemical precipitation methods, to aim for finding the optimum particle size which has high heating efficiency in the applied magnetic field. The obtained powder was calcined at different temperature (600°C, 800°C, 900°C, and 1000°C). The sample which characterized by Transmission Electron Microscopy (TEM) confirmed the formation of single-phase CFNP in the range 10–115 nm depending on the annealing temperature and Vibrating Sample Magnetometer (VSM) to get the magnetization and coercivity of the powder. Localized magnetic particle hyperthermia treatment using ferrimagnetic nanoparticles continue to be an active area of medical application. So, homemade induction heater was designed. The induction heater was designed to be capable of generating high frequency, strong alternative magnetic fields (8 kA·m–1, 135 kHz). In vitro heating efficiencies in test tube, at a MNPs concentration of 250 mg CFNP·ml-1, were measured in the applied field. The temperature increase (ΔT) of the tube content at 60 s was 29.9°C for MNPs of 18 nm, 26.7°C for 25 nm, 25°C for 60 nm and 22.9°C for MNPs of 95 nm. The smallest nanoparticles (18 nm) exhibiting a high heating efficiency. In conclusion, we found that the size of the CFNP increased with increasing the calcined temperature at which the synthesis of the nanoparticles was performed. The heating efficiency of the particles was improved with decreasing particle size from 95 nm to 18 nm in the alternating magnetic field.

The effect of Si addition on hardness, microstructure, and behavior of wear of Al-0.1Mg-0.35 Ni-(4, 6, 8, and 10) wt %Si alloy has been investigated. The alloy is melted in an electric furnace and Si added to the melt in a metal mold. The microstructure for samples and worn surfaces were analyzed and characterized using X-ray diffraction the residual voltage (XRD), energy dispersive spectroscopy (EDS), scanning of electron microscopy (SEM) and atomic force microscopy (AFM), respectively. The results have showed that the Si morphology remained particle shaped and an intermediate phase Al3Ni was observed. The hardness and tensile strength increased, wear rate decreases and the coefficient of friction CoF remained constant. Further, the impact of Si addition on the behaviour of the Al-0.1Mg- 0.35Ni-(4, 6, 8, 10) wt %Si is also evaluated in this study. Finally, it is concluded that the Si addition significantly improves of tribological properties of the Al-0.1Mg-0.35Ni-(4, 6, 8, 10) wt %Si alloy.

Cream cheese produced from pasteurized milk and cream which has soft texture and mild flavor and is one of the most delicious cheese and has high fat and humidity. Nowadays, problems such as obesity, cardiovascular disease, atherosclerosis and cancer are due to consumpting the high fat products, so reducing the fat in foods is very attractive field. In this study, the effect of xanthan gum at level 0.05, 0.17, 0.3 and carboxymethyl cellulose at 0.02, 0.11, 0.2 on chemical and sensory properties of cream cheese was studied. Chemical results showed that there was no significant difference in pH value between treatments. Protein and dry matter content of the samples ranged from 6.005% to 7.31% and 30.02% to 30.975% respectively. Increasing the level of xanthan and CMC in cream cheese resulted in decrease the dry matter content. There was significant difference (p<0.05) in protein and NaCl content between treatments with increase the used gums, but about fat had not effect. The results of sensory properties including texture, flavor, odor, color and overall acceptability showed that replacing xanthan and CMC had not adverse impact on the organoleptical characteristics of cream cheese and general acceptance of the product was good. The lower levels of xanthan in combination with each of the three levels; 0.02, 0.11, 0.2 CMC gum were more acceptable than other samples.

The main purpose of doing this experiment is to find out the condition what happen when two magnets are in normal form. By which side they are being attracted and by which side they are being repelled. And what happen when we flip the magnet? Both flipping one by one. Many of the people doing the experiment are not known what the results are when we flip any one of the magnet to their real position. They are thinking the result should be same. It’s so easy to perform this you only needed two magnet of high power so easily you can observe the results. First take the reading normally and then flip the magnet simultaneous one by one. This gives me incredible results. On just flipping the magnets it just changes its whole properties. On the basis of flipping the magnet mechanically we can design the magnetic motor which would exceed all the available efficiencies. And the one which people are looking for results like over unity motor might be possible by this concept. Because magnetism and electromagnetism are even now missing secrets, and everything is yet to be discovered. The other is to clear the misconception of magnets that the strength of magnet on other side changes when the magnetic dipoles are shifted in other direction. When magnet is attracted or repelled by one side strongly in that situation, what will be the results on other side of it? Either it will be repelled by that force only or the force will be decreased for other side. This result can also be used in making very efficient electric motors.

In this paper, moment-curvature behavior of reinforced concrete column with constant axial load is determined using finite element method and then it is introduced to a single degree of freedom (SDOF) model based on Euler- Bernoulli theory. Using this SDOF model, dynamic response of the RC column under the blast loading is estimated. The introduced SDOF includes secondary moments (P-δ) effects, nonlinear behavior of the material and effects of strain rate on concrete and steel materials through the time calculation of the model. Results obtained from SDOF model for transverse displacement of RC column under blast loading is compared to analysis by finite element software OPENSEES. Then, introduced SDOF method is used for drawing Pressure-Impulse (P-I) diagram of the column with considering the presence of axial compressive load. According to the results, introduced SDOF model has simple and quick computations and accuracy of predictions is acceptable.

This paper presents the results of extensive numerical simulations, based on the control volume method, of 2D nanofluid fluid flow around a heated elliptical cylinder with different incidence angle and aspect ratio. The continuity and momentum equations have been numerically solved using a SIMPLE algorithm. Two types of nanofluids consisting of Al2O3 and CuO nanoparticles dispersed separately in base fluids of water and ethylene glycol mixture 60:40 (by mass), were selected to evaluate their effect on the flow over elliptical cylinder, also their superiority over conventional fluids. The thermo-physical parameters of nanofluid have been estimated using the theory of one fluid phase, a contemporary correlations of thermal conductivity and viscosity of nanofluids have been used in this paper, which are functions of particle volumetric concentration as well as temperature. The results of heat transfer characteristics of nanofluid flow over elliptical cylinder reveled clear improvement comparing with the base fluids. This enhancement is more important in flows with different geometry characteristics of the elliptical cylinder. While the aspect ratio and the incidence angle, exert significant influence on the heat transfer characteristics. The obtained results indicate that the use of aspect ratio 0.83 and incidence angle 79.2° lead to the highest amounts of heat transfer inside the tube.
