The objective of this work was to produce activated carbon chemically from canola seeds wastes and to apply the activated carbon produced in the sorption of Pb and Cd from contaminated water. The activation of the canola seeds wastes was performed with NaOH (1 mol L) for 6 h under constant stirring. Then the activated material was pyrolyzed for 1 h at 750 °C. The activated carbon was subjected to nitroperchloric digestion for the determination of P, K, Ca, Mg, Mn, Zn, Cu and Pb by flame atomic absorption spectrometry (FAAS). It was also realized the thermogravimetric evaluation (TG), infrared spectra (FT-IR), pHPCZ and scanning electron microscopy (SEM). The metals were evaluated for ideal amounts of adsorbent dose and pH and kinetic, thermodynamic and equilibrium parameters. The mass and pH results demonstrated that four grams of adsorbent is needed to decontaminate one liter of contaminated solution. Linearization were obtained by the mathematical models of Langmuir, Freundlich and D-R, with high capacity of removal of both metals. Thus, using canola waste to produce activated carbon it is possible to add value to the canola seed wastes, also, it contributes directly with the economic, social and environmental sustainability of this productive system.

A nanostructured surface is proposed for potential application of anti-icing. This surface integrates microcavities with doubly reentrant nanostructures which can simultaneously enhance static repellency and dynamic pressure resistance. This surface is inspired by the skin structure of a spring tail which can survive even in oil and ethenal. We fabricated nanostructures with overhanging edge which exhibited great wetting resistance ability. It is found that when a droplet impacting on different surfaces, the newly fabricated nanostructured doubly reentrant surface shows a shortest contact duration in comparison with other surfaces. Therefore, the nucleation for icing on a cold doubly reentrant nanostructures is depressed and the surface shows icephobic property. Our new structure showed great wetting resistance ability in both static and dynamic conditions, under low temperature and the theoretical analysis accorded with the existing simulation work. The decrease of contact time for the new surface also gave the potential in applications like anti-icing in the future.

Major challenges for the future transport systems include, inter alia, the reduction of emissions and reasonable energy management. To this end, one of actions popular in recent years is the development of electromobility in cities. This development is often difficult because of the social and infrastructure barriers. The article presents the method that enables to develop electromobility in cities which have a negligible number of charging station. The method is based on new technologies (in this case, multimodal trip planner developed in the framework of an international project Electric Travelling in ERA-NET CoFund Electric Mobility Europe) and acquisition of Big Data determining directly the needs of people travelling. Information gathered can provide a relevant decision-making support while determining the location of charging stations with the objective of promoting electric vehicles.

In this paper, laboratory techniques of removing acid mine drainage rich in iron and sulphate is highlighted. AMD are contaminated water generated from mining of metals rich ore bodies such as pyrites and other iron and sulphide rich minerals. Three waste rocks of shale, bentonite and a mixture rock (shale-bentonite-calcrete) were used in removing the iron-sulphate concentration. Physico-chemical remediating process was carried out in the laboratory targeting the removal of the iron and sulphate in the AMD using these waste rocks. The remediation involved grinding the waste rocks into different particle sizes and sorting the grains using ASTM standard. The sorted waste rocks were arranged into three transparent bottle with regulated dip end. Each waste rock was placed into a distinct bottle. AMD rich in iron-sulphate was sourced from an abandoned mine. The iron-sulphate concentration in the AMD was determined using ICP-MS. The iron-sulphate concentration was determined before and after the remediation. Result show iron concentration in the AMD was 253 mg/l before remediation and 0.08 mg/l, 0.02 mg/l, 0.80 mg/l after remediation for bentonite, mixture and shale respectively. Likewise, sulphate concentration before remediation was 5067 mg/l before remediation and 3207 mg/l, 3662 mg/l, 2238 mg/l after remediation for bentonite, mixture and shale respectively. The laboratory experimentation has shown that controlled laboratory techniques can be used in removal of iron and minimise sulphate contained in AMD. The use of waste rocks of shale or bentonite with variety of grain size contents will remove iron-sulphate contamination and if use as liners in a constructed wetland will minimise the generation of AMD.

Deep-ultraviolet (DUV) light with a wavelength (λ) of 200~300 nm has been spotlighted for the photolysis, water or air purification. Interestingly, DUV light does not exist on the earth surface naturally, because DUV coming from the sun is absorbed by ozone in the atmosphere.[1] Thus, DUV can be used for communication or missile tracking thanks to a weak background interference. For those applications, a development of high-performance DUV photodetector is necessary.[2] DUV detection is also important for sensing biological molecules because some of biological molecules absorption and florescence spectrum is within the range of DUV wavelength.[3] In the meantime, DUV light is dangerous and harmful to human body because of its high energy (>4 eV). Therefore, the development of high-performance DUV photodetector is inevitable to operate the DUV light safely. For the DUV detection, absorber with wide bandgap (>4.5 eV) is required such as AlGaN. Unfortunately, most of existing DUV photodetectors exhibited a poor performance in the DUV detection despite the use of the epitaxial AlGaN layer.[4] In addition, the growth of epitaxial AlGaN layer must be done at high temperature (>1000 C) using complex buffer layers. Ga2O3 is a good candidate for the DUV detection because of its wide bandgap (~5 eV), however, photodetectors using epitaxial Ga2O3 films exhibited a slow response speed with low responsivity.[5] Here, we demonstrated a high-performance DUV photodetector using an amorphous gallium oxide thin films (GaOx) grown by atomic layer deposition (ALD) at a low growth temperature of <250 C for the first time. Interestingly, the amorphous GaOx showed a wide bandgap of (~4.9 eV) which is comparable with epitaxial Ga2O3 films. The photodetector using 30-nm-thick amorphous GaOx film showed a fast response (as short as ~3 us) with high responsivity (~45 A/W at λ = 253 nm) which outperforms conventional DUV photodetectors. The cut-off wavelength is ~ 300 nm that does not respond to visible lights, and the photodetector detects only DUV wavelengths selectively. It should be noted that general substrates such as a glass and quartz can be used for the DUV photodetector owing to the amorphous phase of GaOx film, which enables a practical application of the fabrication protocol. Finally, we demonstrated a flexible DUV photodetector fabricated on polyimide substrate which showed a reliable detection of DUV with the repetitive bending cycles beyond >3000 times at a bending radius of <10 mm. Interestingly, the performance was maintained under the bending radius of <2 mm by a stress engineering. This process scheme will provide an economically useful solution for the development of DUV sensor for various applications.

Globally, diarrhoea is the second leading cause of death among under five children and India alone accounts for 100,000 lives annually, third highest in the world. In low and middle-income countries, contaminated water has been the major source of diarrhoea. It has been seen that lack of improper WaSH (Water, Sanitation and Hygiene) practices accounts for 90% of the total death due to diarrhoea. Objective: To determine the bacteriological quality of drinking water and diarrhoeal morbidity among under five children and to assess the WaSH (Water, Sanitation and Hygiene) practices among children and mothers/care givers. Materials and Methods: A community based cross-sectional study conducted in resettlement colony, Kalyanpuri of Delhi. A total of 553 under five children were studied after attaining consent from mothers/care givers. MPN count per 100 ml was measured from point source as well as drinking water storage vessel. Result: Prevalence of diarrhoea was found to be 40.2% in the period between January 2018 to December 2018. It was found to be more prevalent among children aged between 13-24 months (57.3%). On assessing the bacteriological quality of water samples, 37% of samples were unsatisfactory, 36% suspicious and 22% satisfactory. None of the samples were found to be satisfactory. On assessing the WaSH practices, it was observed that the mother/care givers lacked the knowledge and importance of hand hygiene and sanitation practices. Conclusion: Diarrhoea being a preventable disease yet takes a heavy toll of lives of children. Mere awareness without behaviour change cannot reduce the burden of diarrhoea. Education on WaSH practices, their acceptance and also on household water treatment and storage practices can have a major impact on the burden of diarrhoeal diseases.

Extended Abstract Aim: To conduct water quality assessment in the public beachfront in the urban area of Mariveles town in Bataan, Philippines and compare the results with the previous evaluation. Methods: Four public bathing sites were revisited. Three water samples in each site were collected during the premonsoon season (March 2019) using sterilized bottles for three consecutive weeks. The samples were tested for three bacteriological parameters, namely, faecal coliform, total coliform and heterotrophic plate count. Total coliforms and faecal coliforms have been historically used to establish bathing water quality. Results: As basis, the researchers used the latest version of the Philippine National Standards for Drinking-Water, which also complies with the standards set by the World Health Organization [1]. Both faecal coliform and total coliform were greater than 8.0 MPN/100 mL in most of the samples. Heterotrophic plate count (in CFU/100 mL) was highest in the location near the outlet of Santol river (M = 2138.9, SD = 1664.7) and lowest for Matel beach (M = 281.11, SD = 120.25). Using a one-way analysis of variance, the study showed that there was no significant difference in the HPC of the four sampling locations in the present study. With a one-sample T-test, the researchers found that the water samples did not meet the standards set by the DOH and WHO. Compared with the previous study, a significant decrease in average HPC was observed in the location near the breakwater. Although there was also a decrease in the mean HPC of the location near Santol river and London Drug, the reduction was insignificant. On the contrary, an increase in average HPC was seen on Matel beach. Conclusions: The locations are still classified as high risk mainly due to faecal coliform concentrations, as well as the other two parameters. Public bathers can face gastrointestinal risks when they (accidentally) drink water from these locations. Thus, the water from the studied locations is not recommended for public bathing. Significance of the Study: The results presented in this research can be used as data in tracking the progress of the recent implementation of policies made by the local government of Mariveles geared towards improving the water quality in its town.

Significance of the Study: The results presented in this research can be used as data in tracking the progress of the recent implementation of policies made by the local government of Mariveles geared towards improving the water quality in its town.","PeriodicalId":265434,"journal":{"name":"Proceedings of the 5th World Congress on New Technologies","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115271290","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}

In order to estimate indoor natural radioactivity levels, long and short-term radon tests and ambient gamma dose rate measurements have been performed in several environments of the Faculty of Engineering and in the student canteen of Cagliari University. The measured values were found below the recommended reference levels issued by Directive 2013/59/Euratom. Consistent information about building characteristics, living habits and exposure times were recorded, to be taken into account in the UNSCEAR model. The annual effective dose calculated for each room ranges from 0.004 to 0.628 mSvy. The levels of radon concentration measured until now did not exceed the recommended threshold values; additional testing will be performed to ensure full compliance of indoor air quality requirements.
