The Effect of Electrospinning Parameters on Piezoelectric PVDF-TrFE Nanofibers: Experimental and Simulation Study
No full textPolyvinylidene fluoride and its copolymers can be used as active materials for energy harvesting and environmental sensing. Energy harvesting is one of the most recent research techniques for producing stable electrical energy from mechanical sources. Polyvinylidene fluoride–trifluoroethylene (PVDF-TrFE) is applicable for sensors and self-powered devices such as medical implants and wearable electronic devices. The preparation of electrospun P(VDF-TrFE) nanofibers is of great interest for the fabrication of sensors and self-powered devices, nanogenerators, and sensors. In this regard, it is necessary to investigate the effects of various parameters on the morphology and piezoelectric output voltage of such nanofibers. In this study, we have examined the effect of concentration and feed rate on the nanofiber diameter. It has been found that by increasing the concentration and feed rate of the polymer solution, the diameter of the nanofibers increases. The experimental results and the finite element method (FEM) simulation have also shown consistency; when the nanofiber diameter increases, the output voltage of the nanofibers decreases. This behavior can be related to the strain reduction in the deformed nanofibers
Development of Porous Polyacrylonitrile Composite Fibers: New Precursor Fibers with High Thermal Stability
No full textPolyacrylonitrile (PAN) fibers with unique properties are becoming increasingly important as precursors for the fabrication of carbon fibers. Here, we suggest the preparation of porous PAN composite fibers to increase the homogeneity and thermal stability of the fibers. Based on the thermodynamics of polymer solutions, the ternary phase diagram of the PAN/H2O/Dimethylformamide (DMF) system has been modeled to introduce porosity in the fibers. Adding a conscious amount of water (4.1 wt.%) as a non-solvent to the PAN solution containing 1 wt.% of graphene oxide (GO), followed by wet spinning, has led to the preparation of porous composite fibers with high thermal stability and unique physicochemical properties. Differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) results elucidate that PAN/GO/H2O porous composite fibers have a higher thermal decomposition temperature, increased residual weight, reduced heat release rate, and higher crystallinity in comparison with the pristine PAN fibers, being a promising precursor for the development of high-performance carbon fibers. The results show a promising application window of the synthesized PAN fibers in electronic and electrochemical devices

No full textIsolation of resonance in acoustic backscatter from elastic targets using adaptive estimation schemes
No full textThe problem of underwater target detection and classification from acoustic backscatter is the central focus of this paper. It has been shown that at certain frequencies the acoustic backscatter from elastic targets exhibits certain resonance behavior which closely relates to the physical properties of the target such as dimension, thickness, and composition. Several techniques in both the time domain and frequency domain have been developed to characterize the resonance phenomena in acoustic backscatter from spherical or cylindrical thin shells. The purpose of this paper is to develop an automated approach for identifying the presence of resonance in the acoustic backscatter from an unknown target by isolating the resonance part from the specular contribution. An adaptive transversal filter structure is used to estimate the specular part of the backscatter and consequently the error signal would provide an estimate of the resonance part. An important aspect of this scheme lies in the fact that it does not require an underlying model for the elastic return. The adaptation rule is based upon fast Recursive Least Squares (RLS) learning. The approach taken in this paper is general in the sense that it can be applied to targets of unknown geometry and thickness and, further, does not require any a priori information about the target and/or the environment. Test results on acoustic data are presented which indicate the effectiveness of the proposed approach.The work of M. R.

1938 revisited? Should doors open wider to Syrian refugees?
No full textDoes it seem that every time the world watches refugees flee violence and persecution while politicians claim their country can\u27t possibly take in asylum seekers, we lamentingly claim that the world will never again turn its back on these people.
And yet the next time we seem people streaming out of a war zone with nothing but their families and the shirts on their back we forget the promise we made the last time this happened?
For a world that promised \u27Never Again\u27 after World War II, how much have we actually learned from the handling of refugee crises of the past? Are we making the same mistakes over and over again?
Do you see echoes of the treatment of Jews fleeing the Holocaust in government rhetoric about refugees from Syria and Iraq? And if so, what explains this short-sightedness?

Wave-Induced Currents Within Mangrove Forest
No full textMangroves are tidal trees commonly observed along the sheltered shorelines of most tropical (from equator to 23.5° North and South latitude) and few subtropical (23.5° to 40° North and South latitude) countries. These plants are adapted to loose wet soils, saline habitats and periodic tidal submergence. With more attention paid into the approach of building with nature, natural coastal defence strategies are gaining more importance as an asset in addressing the coastal squeeze that is prevalent not only in urban areas, but also in agriculture and industrial areas that are located along the coastline. Mangroves are receiving more attention due to their coastal protective role against wave and hydrodynamic forcings as well as their ability to adapt to sea level rise. Mangrove vegetation attenuates and damps the hydrodynamics forcings by providing obstacles to the flows and creating drag. To date and to the knowledge of the author, no study has been conducted on interaction of the wave-induced currents with mangrove vegetation. This lack of relevant studies may be due to the fact that mangrove forests and the foreshore in front of the mangroves are usually of very gently sloping bed (varying in order of 1:300 to 1:1500). This means that in order to conduct physical model experiments to study wave-induced current within a mangrove forest, a very large wave basin is required in order to conduct modelling without using a very large scale factor difference between prototype and model. This is to ensure that the relevant processes are representing prototype as closely as possible, as well as to be measureable. Numerical modelling of the interaction of wave-induced current with mangrove vegetation is yet to be conducted due to the lack of measured data for validation, both field as well as experimental measurements. An experiment by Hulsbergen (1973) was selected as validation data for current study. The main objective of the study is to understand the difference of nearshore processes for (stationary) tidal gradient-driven and oblique wave-driven current for both with and without mimic mangrove vegetation. The scope of the study involves desktop analysis of the main validation data and other relevant and similar experiments, assessment of reliability of Delft3D for the study, validation against measured data, and simulation of various hydraulic conditions for condition with mangrove forest. Among questions answered in this study are the extent of wave-induced longshore current damping within mangrove forest, the significance of wave-induced longshore current within mangrove forest, the effects of bed slope and mangrove density on wave-induced current and the extent of model’s reliability for current study. It was shown that the damping of wave-induced longshore current is more than 80% and the contribution of waveinduced current to the total velocity can be more than 70%. Of course, both of the above was specific to the bathymetry, mangrove properties and hydraulic conditions specified within current study. Furthermore, it was shown that bed slope and mangrove density affect wave-induced longshore current within the mangrove forest. It was also found that current model setup has its limitations.Civil Engineering | Hydraulic Engineering | Coastal Engineerin
Change in Attitude in Renal Function in Major Beta Thalassemia
No full textThalassemia is a multisystemic disease in the field of hemolysis and chronic anemia caused by the erythropoietic disorder. The severe effects of iron overload from continuous blood transfusion iron chelators side effects, and involvement of multiple organs in thalassemias such as heart failure, liver, and endocrine dysfunction can all affect kidney function. Although there has been much debate about changes in renal function in thalassemia for many years, the presence of hyperfiltration and ultimately, decreased renal function in almost all studies. It seems for the researchers to look beyond kidney function in a thalassemia perspective, because of secretory biomarkers of proximal tubular renal cells that are sensitive to pathologic agents, which may be a good indicator of the courses of treatment and prognosis of patients. Future studies will be sooner or later.
