Since the demand is very high, it is impossible to power up the entire world using petrol and diesel. The depletion of fossil fuels and the worst impact on environmental pollution have led to the search for renewable clean energies. Micro algae are presently the favourable source of biofuels for the substitution of fossil fuels. This study focused on to extract bio-oil from the Botryococcus algae which has high lipid content, by using pyrolysis method. The Botryococcus algae oil is used as the biofuel in the direct injection (DI) diesel engine. The 90% diesel is blended with 10% Botryococcus algae oil and the test was carried out to analyse the effect of diesel-biofuel on the engine performance, emission and properties such as SFC, BTE, CO, NOx and HC. The experiment was conducted on a single cylinder four stroke diesel engine with diesel and biofuel blend at varying loads. The performance and emission results of the blended biofuel and diesel were compared, and the performance results, shows the biofuel blend is almost closer to the diesel, and the biofuel blend gives less emission than the diesel.","PeriodicalId":35407,"journal":{"name":"Progress in Industrial Ecology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43621274","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Initially, vibration sources were collected from the wind turbine using piezoelectric accelerometer and from that vibration source; needed features are extracted using ARMA through MATLAB.

In this experimental work, the diesel engine has initially run by diesel alone, secondly, 10% cottonseed methyl ester biodiesel (B10) and finally emulsion of 10% water with B10 (WiB10E) in combination. The emulsified biodiesel WiB10E shows the maximum reduction of NOX emissions in comparison with the pure diesel and B10 fuel operations. Also, due to the cooling effect provided by the water in the combustion chamber, the WiB10E shows the slight increase of the HC and CO emissions. Since WiB10E fuel has a boiling point difference, it leads to secondary atomisation. The WiB10E has shown the higher cylinder pressure of 65.92 bars at a crank angle of 366° due to microexplosion. Hence, emulsified biodiesel fuel is efficient in the reduction of NOX emissions amongst all the techniques.","PeriodicalId":35407,"journal":{"name":"Progress in Industrial Ecology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42186278","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main purpose of this paper is to investigate the effects of different EVs' charging and discharging strategies in a SM. With EVs and absence of DERs and therefore satisfaction of the full load from the upstream network, is considered as the base case. For each scenario, six different charging technologies are examined. In addition, three different pricing policies based on system marginal price (SMP) are considered.

This paper describes the preparation of thin films ZnSe with V, In and Cu doped using thermal evaporation method with a vacuum of 10-5 Torr. The thin film was obtained from this work could be applied in heterojunction solar cell because of several advantages including high absorption coefficient value and direct band gap. The samples prepared on a glass and n-type Si wafer substrate. These films have been annealed for 1 h in 450 K. X-ray diffraction XRD results indicated that ZnSe thin film possesses poly-crystalline structure after doping with preferential orientation (111) and the atomic force microscopy (AFM) were used to examine the surface morphology. Optical studies were done using UV-Visible spectroscopy and the band gap energy was found to decrease with doping. Hall measurements showed that all the films are p-type with high carriers concentration (3.26 × 1017 cm-3) in ZnSe:Cu thin film. The built in potential was determined from the C-V measurements which revealed an abrupt junction for all heterojunction samples. The conversion efficiency calculated from dark and illuminated I-V characteristics of ZnSe/Si solar cell pure and doping. The chances for achieve type of doping can be improved by designing growth conditions that destabilise the formation of compensating centres, which is important for optical device applications, the effect of doping on main different factors such as open-circuit voltage, short-circuit current density, fill factor, the photovoltaic conversion efficiency of ZnSe pure and doped.

Meanwhile, the results of t test and Pareto charts reveal that UV irradiation time and weight fraction have a positive effect on the responses. However, the influence of pH on the removal efficiency of methyl orange is negative.
