Estimation of Electrical Performance of a Polymer Insulator with Deposited Moss on the Surface under Impulse Voltage Condition in Foggy Weather

This paper presents a study about electric field behaviour of 10kV polymer insulator with moss deposition under foggy condition. The aim of this simulation experiment was to determine if this field affect the initiation of pollution flashover. To study this effect, simulations were carried out using High Frequency Structure Simulator (HFSS). The simulation experiment includes the results of electric field distribution along the insulator and also the magnitude of electric field at three different locations in identifying the parts of the insulator’s surface that likely to initiate pollution flashover. The moss deposited polymer insulator displayed uniformed and considerably intense distribution of electric field with the clean insulator. The field result showed the likelihood in discharging a corona effect. In short, the results indicated that electric field along the insulator surface would likely be influenced by moss deposition and foggy air.

The Expectations of Businesses Settled in a Science Park

Science parks are created to support the development and growth of knowledge-based businesses and to foster the economic development of a region. Based on an exploratory qualitative study, this research project aims, firstly, to understand the expectations of businesses established in science parks, which is not very well documented in the literature and, secondly, to highlight the motivations of a business to settle in a science park. In order to do so, the research is based on a constructivist approach. Twelve semi-structured interviews were conducted between September 2016 and April 2017 with managers of organizations established in seven science parks in the province of Quebec, Canada. The analysis these interviews identified six major motivations of businesses to settle in a science park. It also revealed eleven major expectations of the science park's contributions for a business established. As a contribution, this research provides some recommendations not only for the managers of science parks, but also for the managers of businesses who want to be established in a science park. This research provides insights for science park managers about the incentives to set up to attract new business and about the support to provide for the business established in a science park in their development.

Sericin Ameliorates the Properties of Poly(Vinyl Alcohol) Hydrogel Prepared by Simple Repeated Freeze-Thaw Process without the Use of Chemical Crosslinking

Hydrogel of polyvinyl alcohol (PVA) and sericin can be easily produced using a repeated freeze-thaw process. The effects of polymer concentration (4-8 %wt), blending ratio of PVA/sericin (100/0-50/50), and the number of freeze-thawing cycle (4, 8, and 12 cycles) on chemical and physical properties of the hydrogels obtained were studied. We here showed that higher polymer concentration, higher PVA ratio, and more cycles of freeze-thawing produced the hydrogels with high gel (crosslinked) fraction (>90), wall-like structure, and high compressive modulus (100-170 kPa). When the sericin ratio was increased, the hydrogels showed less gel fraction (60-80), more porous structure with highly interconnected pores, and better swelling ability (up to 8-9 times of its original state). The formation of the PVA/sericin hydrogels was occurred by the conformational changes of both PVA and sericin. The secondary structures of PVA and sericin turned to more stable crystalline conformation during the freeze-thawing process, as confirmed by fourier transform infrared (FTIR) spectroscopic results. Furthermore, all hydrogels were not toxic to human skin keratinocytes (HaCaT) cells while the anti-oxidant activity of sericin component in hydrogels was confirmed. We concluded that the freeze-thawing process was a simple and effective technique for fabrication of PVA and sericin, which both are water-soluble, into the stable hydrogels without the use of any chemical solvents or further crosslinking. More importantly, sericin enhances the biological activities of the hydrogels, allowing the use of this hydrogel in various medical applications such as wound dressing.

Influence of Crosslinking Agent Concentration on The Microencapsulation Parameters of Collagen Hydrolysate-Walled Microcapsules

Despite being a lot of discussion, a large amount of chrome tanned leather is still being tanned in the world. After tanning with chrome, chrome solid leather wastes occurred. These chrome wastes arise during mechanical processes such as trimming, shaving, buffing and splitting. These solid wastes containing trivalent chromium and may be oxidized to hexavalent chromium by the appropriate conditions in the landfill areas. Increasing environmental awareness and regulations have been making great pressure on the leather industry. Nowadays, solid leather wastes tanned with chromium are assessed by hydrolysis with the enzyme in high alkaline media and can subsequently be used for several applications. However, there is still no definitive solution to these chromed solid leather wastes. In this study, microcapsules of collagen hydrolysate cross-linked with glutaraldehyde containing Lavender essential oil were prepared by coacervation method. The influence of crosslinking agent concentration on the oil load (%), oil content (%) and encapsulation efficiency (%) of lavender oil microcapsules were investigated. As the crosslinking agent concentration increased, the oil load (%) decreased but oil content (%) and encapsulation efficiency (%) of microcapsules increased. The best result obtained by using 5 g of collagen hydrolysate, 7 ml of glutaraldehyde and 7 ml of lavender oil.

Preparation and Characterization of Nano Titania modified PVA-Pectin polymer electrolyte membranes for DMFC

In this study, poly vinyl alcohol and pectin are in situ cross-linked using dual cross-linker comprising a mixture of sulfosuccinic acid and glutaraldehyde followed by solvent casting.Titanium dioxide nanoparticles are incorporated into polymer solutions that controls alignment and disentanglement of polymer chains at molecular level. It is shown that rational design of membrane microstructure with proper arrangement of hydrophobic and hydrophilic domains has been formulated by blending PVA with PC. Water sorption through nanocomposite membrane enhanced when optimum quantity of titanium dioxide particles are present. In addition, titanium dioxide nanoparticles help to provide more inter-connected proton conducting pathways and acts as reinforcing units. Through the hydrogen bonds formed between surface functional groups of titanium oxide nanoparticles and polymer chains, protons are transferred through the membrane both by hopping and vehicular mechanisms. Titanium dioxide nanoparticles also act as fillers and effectively prevent the methanol permeation. Polymer voids are occupied by the presence of Titanium dioxide nanoparticles that selectively allow protons to pass through form anode to cathode side. Both improved proton conductance and lower methanol permeability, electrochemical selectivity of nano Titanium dioxide modified PVA-Pectin polymer electrolyte membrane is enhanced. With further enriched proton conductivity by the presence of titanium dioxide nanoparticles, fabricated pectin polyvinyl alcohol hybrid nanocomposite membrane exhibit higher electrochemical selective factor.

Why should a Laboratory be required for Linear Circuits I ?

When in the fall semester of 2017 at the University of Pittsburgh at Bradford, a Laboratory was added to Linear Circuits I , it provided an absolute amazing insight into the absence of practical knowledge of students. They could not identify resistors, or capacitors. They had in most cases no idea what a DMM was and how to use it. Setting up fairly simple circuits on a proto-board and making voltage and current measurements had to be shown to each Lab group. A Lab experiment with an Op-Amp meant, that several of the Op-Amps were sacrificed to the smoke god. Students were amazed by what an Oscilloscope could do and how one could see the charge and discharge of a capacitor. At the end of each experiment, MatLab was used to verify the practical results obtained. What was gratifying at the end of the semester that each student group had high praise for the inclusion of a Laboratory into the curriculum. All the frustration and the extra work involved was worth it if one looked at the final result and that a practical component had been added to the students background, which would serve them well in a summer internship or in the Co-op program.

The Accumulation of Heavy Metals in Leaves of Woody and Vegetable Plants

It is shown that the improvement of the environment can be achieved by using the adsorption properties of leaves of woody plants, which are able to absorb the exhaust gases from vehicles, industrial plants, dust and vapors from air. The number of toxic influence of heavy metals on vegetable plants was established with good indicative properties: Cd > Ni >Pb. Accumulation of heavy metals, leaves of the juniper have any symptoms of poisoning, inhibition of root growth, formation of necrosis, dwarfism, wilting, dropping foliage, etc, especially in leaves exposed to cadmium. Different kinds of heavy metals have their own specifics, which defining the maximum level of exposure in the investigated samples. Virtually all heavy metal compounds are toxic and have carcinogenic effect.It should be noted that the main source of it are the smokestacks of factories, the industrial enterprises and exhaust gases from vehicles. If there is an excess of heavy metals, occur symptoms on plants - growth noticeably slows, getting a dwarf form.Thus, on the basis of obtained date, we get conclusion, that the accumulation of heavy metals by leaves of woody plants, in our casejuniper and oak, is due to the passage of the adsorption process of toxic metals contained in the air basin.

Characterization of P(Hema-Gma)-Ida Membrane to Adsorbing Leather Dye

Different chemical substances and too much water are used during leather production. Therefore, the waste water load of the leather industry is harmful to the environment. One of the pollution source is the production of leather coloring process is a further need to focus on the removal of dye waste waters subject. These water-soluble dyes have a small organic molecular size. Besides the environmental hazards that these dyes cannot be underestimated, they also have harmful effects on human health. In this study, poly (hydroxyethyl methacrylate-glycidyl methacrylate) p (HEMA-GMA) hydrogel membranes were synthesized by UV polymerization method. The hydrogel synthesized is modified with imino diacetic acid (IDA) and then chelated with trivalent chromium ions. The chelating capacity of the membranes were determined according to the time, pH and concentration parameters. Dynamic swelling test, elemental analysis, ninhydrin analysis and adsorption, desorption and reusability performances of membranes were also determined. As a result of the analyzes, it was understood that the hydrogel membrane had high adsorption capacity. The adsorption capacity of the p (HEMA-GMA) -IDA-Cr (III) hydrogel membrane did not decrease even after 5 desorption. At the end of the fifth cycle, the membrane was found to have a dye-binding capacity of about 92%. According to these results, the reusable property of the membrane also makes it cost effective as well as effective adsorption.

Study of Convert Waste Stabilization Pond Geometry to Treated Wastewater Efficiency, (El- Burullus Lake, Egypt) As a Case Study

The simulation of hydrodynamics water quality in ponds is a developing tool that worth studying in order to understand their internal processes and interactions. Pond design involves several physical, hydrological, geometrical, biological and dynamic variables to provide high hydrodynamic efficiency and maximum substrate utilization rates. Computational fluid dynamic modelling (CFD) allows the combination of these factors to predict the behavior of ponds by using different configurations. In this research mathematical model developed by Danish Hydraulic Institute (DHI), was formulated to simulate WQ parameter. This model was calibrated and used to simulate a scenario to improve study reach water quality in polluted lakes. The study applied on El-Burullus Lake, which is the second largest northern lake in Egypt which belongs to high eutrophic lake type and suffers from several problems. The model was run at steady and variable state with raw wastewater to study the real effect of the polluted drains, which discharge high amount of polluted wastewater into the El-Burullus Lake and know the lake situation after make baffles scenario. The major functions performed by baffles are to reduce hydraulic short-circuiting and to provide a submerged surface which can encourage the growth of attached biomass. Attached biomass growing on the surface of the baffles could increase the total mass of organisms in the pond and thus improve the treatment efficiency and therefore reduce the eutrophication rate in the pond such as (NH3-N, PO4-P and NO3-N). Results showed that there are a significant variance between the rate of NH3-N, PO4-P and NO3-N before and after make baffles, and the overlap between baffles (L=0.50 baffle) is more efficient than no overlap. In conclusion, waste ponds and be improved easily and economically to be more efficient by making baffles in the lake which can increase the water velocity, avoided the dead zones area and reduce the eutrophic concentration.
