Title: Thermoplasmonic response of Au@SiO2 core–shell nanoparticles in deionized water and poly-vinylpyrrolidone matrix

Abstract:Abstract: Metal-dielectric core–shell nanoparticles strongly absorb light and convert into an efficient localized heat source in the presence of electromagnatic radiation at their plasmonic resonance. This process can be enhanced depending on the size, shape, structure, and surrounding media. This study theoretically and experimentally investigated the thermoplasmonic effects of Au@SiO2 core–shell nanoparticles immersed in water and poly-vinylpyrrolidone prepared through laser ablation in liquid. Two lasers (532 nm cw Nd:YAG and 520 nm fs pulsed ytterbium fiber) were used to illuminate the prepared samples. The theoretical thermoplasmonic response of the samples was estimated based on the finite element method of COMSOL multiphysics V5.2a. The generated heat difference of Au@SiO2 in both media with fs pulsed laser irradiation was higher than that of cw laser regarding the power used due to the heat confinement during the time of the pulse that cannot be disspated. This study can serve as a basis for using plasmonic core–shell nanoparticles as a nanoheat source in medical applications.




Title: Fractal Dimension of Gills, Stomach and Lymphoid Organ of White Shrimp Litopenaeus Vannamei Infected with White Spot Virus

Abstract:In the present work we obtain the fractal dimension of the white shrimp Litopenaeus Vannamei (L.V.) infected with the white spot virus, from a two-dimensional point of view. This fractal dimension was obtained by applying the box counting method and implementing it in a program in Matlab, on digital images of histological sections of the stomach, gills and lymphatic organ. The method showed that healthy cuts manifest a non-linearity smaller than the damaged cuts, at least, clearly for the gills and lymphoid. Interestingly, the stomach showed an inverse behavior, showing a greater fractal dimension in its healthy cut.




Title: WOUND HEALING EFFECTS OF KRILL OIL AND ITS COMBINATION WITH OSTEOPONTIN IN RATS

Abstract:Background and Objectives: Wound healing involves the interaction between various cell types, the extracellular matrix, cytokines, and growth factors. Osteopontin and krill oil have medicinal properties that affect wound healing. Research indicates that krill oil acts as an anti-inflammatory, antioxidant, and tissue renewal agent, whereas osteopontin acts as an anti-inflammatory mediator. The aim of the present study was to examine the effect of krill oil and its combination with osteopontin in the healing and repair of wounded skin.\nMaterials and Methods: Forty-five adult male rats (aged 12 weeks and weighing 175±5.2 g) were allocated to three groups (15 rats per group). Skin wound incision was performed in the right thigh area. Rats were treated daily with a local application of 1 µL of normal saline (control), 1 µL of krill oil, or 1 µL of combined krill oil and osteopontin (1:1 v/v). After 1, 5, and 10 days, five rats from each group were euthanised and samples from the wound area were examined by histology.\nResults: Histology revealed obvious sequential acceleration of wound healing in the combined krill oil and osteopontin-treated rats compared with that of the other groups throughout the experimental period. Improvements were observed with regard to epithelial thickness, inflammatory cell infiltration, and contraction of the wound area.\nConclusion: Local applications of combined krill oil and osteopontin have therapeutic potency to improve wound healing. These agents have potential for future clinical applications.




Title: Studying the effect of nanolead concentration doped in polymethyl methacrylate (PMMA) and anthracene on Build up factor

Abstract:In this research, we have studied the shielding properties against gamma ray with energy (0.662MeV) emitted from the radioactive source of (Cs-137) and activity 0.8mCi. These shields made of polymethyl methacrylate (PMMA), anthracene supported by nano lead. The emitted gamma rays are detected by sodium iodide detector supported by thallium NaI(Tl). Buildup factor were calculated as a function for the concentration of lead in the shields in range of (0.5,2,5,7,10%), and as well as buildup factor are calculated for shielding thickness of shields (PMMA) that supported by a concentration of (25%) of nano lead powder in the thickness range of (1, 1.5, 2 ,2.5, 3)cm. The results showed a decrease in the buildup factor with increasing the concentration, while the observed increase in the buildup factor with increasing the thickness of shields with constant concentration (25%) the best composites used (the lowest of buildup factor). Study of the Buildup factor for all shields samples with concentration (10%) showed that the buildup factor value is greater in pure shielding of polymethyl methacrylate (PMMA) and anthracene (without any substance addition), and lower as possible of the buildup factor value as in case of strengthening the polymethyl methacrylate (PMMA), anthracene with concentration (10%) supported by nano-lead.




Title: Development of cost-effective photovoltaic supervision system using Arduino and MATLAB/Simulink platform

Abstract:This paper presents the development of a photovoltaic (PV) supervision system for commercial PV modules by integrating both Arduino-based data acquisition (DAQ) and MATLAB/Simulink platform, which can provide the function of monitoring, evaluation and warning functions. The measurement data of not only the irradiance but the cell temperature, voltage, and current of PV devices are acquired through an Arduino Mega 2560 board. These measurements are monitored and further input to the built-in PV model for theoretical simulation in the MATLAB/Simulink environment. The comparison between measurement and simulation results for PV performance evaluation under practical working conditions are conducted at the same software platform. A fault detection function is built in the following evaluation. The proposed system has been proved to have both accuracy and confidence in the functions of monitoring, evaluation, and fault detection. As compared with the well-developed ones, the proposed system has the advantage of unification for monitoring, evaluation, and fault detection solely in the MATLAB/Simulink platform.




Title: A Study on Calculation of Surface Roughness in External Plunge Centerless Grinding Process

Abstract:This paper introduces a study on calculation of surface roughness when external plunge centerless grinding. In the study, based on the theory of grinding process, the relationship between the surface roughness and the grinding process parameters including the grinding wheel parameters, the workpiece parameters and so on was taken into account. The results of the surface roughness when external plunge centerless grinding are in agreement with the experimental data. Therefore, they can be used for prediction of the surface roughness in practice.




Title: Review: Unit Root Test in Bounded AR Models

Abstract:Despite of extensive literature on modeling non-stationary economic time series, a controversial and rarely discussed topic is how to interpret and analyze time series whose behavior can be well approximated by means of integrated processes I(1) but are ‘limited’ in the sense that their range is constrained in some ways, which are called ‘bounded time series’. So far, very little work has been undertaken to develop unit root tests which can be applied to bounded time series. it is noted that there are three methods of estimation the test statistics of unit root in bounded AR models which are ordinary least squares (OLS), generalized least squares (GLS), and maximum likelihood (ML). A review of the unit root tests in bounded AR models with these methods of estimation are presented here.




Title: The Effect of Dexmedetomidine on Vancomycin-induced Nephrotoxicity in Rats

Abstract:Background: In this study, we aimed to investigate the protective effect of dexmedetomidine on nephrotoxicity and the mechanism of renoprotection following vancomycin-induced nephrotoxicity in rats.\nMethods: Thirty-two albino Wistar rats were divided into four groups of equal sizes. Group C received intraperitoneal (IP) physiological saline solution, Group V received IP 200 mg k-1 vancomycin, Group D received IP 5 µg k-1 dexmedetomidine, and Group V+D received IP 200 mg k-1 vancomycin followed by IP 5 µg k-1 dexmedetomidine 20 minutes after the vancomycin injection. All injections were given every 12 hours apart, for seven days. The renal tissue samples were examined histopathologically. The serum levels of the BUN, Cr, ET-1, NO, TAS, and TOS were evaluated.\nResults: BUN level was significantly higher in Group V compared to the other groups (p<0.05). Cr levels were significantly higher in Group V and Group V+D compared to Group C (p<0.05). The ET-1 level was significantly higher in Group V compared to the other groups (Group V = 244.87 ± 13.3, Group C = 205.04 ± 3.2, Group D = 194.40 ± 7.5, and Group V+D = 231.90 ± 8.6). NO levels were statistically lower in Group V and Group V+D compared to Group C and Group D. Histopathologic assessment revealed that Grade 3 damage was significantly higher in Group V (n = 4) compared to Group V+D (n = 0).\nConclusions: It was determined that vancomycin could stimulate vasoconstrictive mechanisms and inhibit vasodilator mediators, thus causing renal damage. It was also determined that dexmedetomidine, in the dosage applied in the study, can create the opposite effect and reduce the extent of the damage.
