Development of hydrophilic GO-ZnO/PES membranes for treatment of pharmaceutical wastewater
Authors: Mahlangu O. T. , Nackaerts R. , Mamba B. B. , Verliefde A. R. D.
Published: March 2017

Membrane application in water reclamation is challenged by fouling which deteriorates membrane performance in terms of permeate flux and solute rejection. Several studies focusing on antifouling membranes incorporated with nanoparticles have been carried out, but these membranes are not yet a viable solution due to their high energy requirements and inability to completely remove or degrade trace organic compounds (TOrCs). Therefore, this study aims at fabricating polyethersulfone (PES) membranes for treatment of pharmaceutical wastewater by using a unique membrane synthesis approach. PES membranes were synthesised by casting two different solutions before coagulation. Therefore, the synthesis technique was called ‘double-casting phase inversion’. The membranes were impregnated with nanohybrid graphene oxide-zinc oxide (GO-ZnO) to increase their hydrophilicity, rejection of pharmaceuticals (by decreasing membrane-solute hydrophobic interactions), resistance to organic fouling and photodegradation properties. The addition of GO-ZnO increased membrane hydrophilicity and pure water permeability. The rejection of TOrCs and anti-fouling properties were also improved due to a reduction in membrane-solute and membrane-foulant hydrophobic interactions, respectively. In addition to improved TOrC rejection properties and resistance to fouling, GO-ZnO/PES membranes degraded Brilliant Black.

Published: March 2017

The increasing need in techniques of storing big data presents a new challenge. One way to address this challenge is the use of distributed storage systems. One strategy that implemented in distributed data storage systems is the use of Erasure Code which applied to network coding. The code used in this technique is based on the algebraic structure which is called as vector space. Some studies have also been carried out to create code that is based on other algebraic structures such as module.  In this study, we are going to try to set up a code based on the algebraic structure which is a generalization of the module that is semimodule by utilizing the max operations and sum operations at max plus algebra. The results of this study indicate that the max operation and the addition operation on max plus algebra cannot be used to establish a semimodule code, but by modifying the operation "+" as "min", we get a code based on semimodule. Keywords:   code, distributed storage systems, network coding, semimodule, max plus algebra

Published: March 2017

Heavy metals such as nickel and cadmium from the waste of human activities (industry, domestic,) can lead the pollution and sediments deposited on the seabed. Water pH changing, can lead to the release (leaching) metals in the sediment into the water body and then it will be bioaccumulated on biota arround the environment. To see the effect of pH changing on the release (leaching) of these metals, extracting the sediment at pH variations has done (TCLP method). From the results of detection metals cadmium (Cd) and nickel (Ni) release studies, to see the hazards of cadmium and nickel metal, carried out a simulation of bioaccumulation test on biota using bioindikator Cyprinus carpio (OECD Guideline 305). Based on the analysis of data obtained in the nickel content in the sediment extract pH 3, 5 and 7 reached 2.55 to 27.94 µg/g, while for cadmium reaches 4.31 to 4.68 µg/g. Observation of metallic nickel and cadmium bioaccumulation in fish hass done for 28 days by looking at levels of cadmium and nickel on the gills of fish and meat. In the flesh of fish, the highest cadmium concentration of 3.179 µg/g while in the gills is 5.392 µg/g. The highest nickel concentrations in fish flesh is equal to 4.557 µg/g while for gill is equal to 10.417 µg/g. The study results indicate the presence of cadmium and nickel metal accumulation on biota. Keywords: TCLP method, biota, Cyprinus carpio

It is considerably challenging task to have a buffer zone (BZ) around protected areas (PA) in the urban area due to the conflict of interest between conservation and development. There is a need for ‘win-win situation’. This research is to identify the impact of a potential buffer zone on human and conservation of natural environment which derived from the stakeholders’ understanding. In-depth interviews with stakeholders of the PA and their surroundings were carried out. The findings suggested that a ‘dual purpose’ BZ – environmental conservation and socio-economic benefits are suitable for the FRIM area.Keywords:; Buffer Zone Concept; Protected Areas; Urban Setting; FRIM, MalaysiaISSN: 2398-4287© 2017.

Unique Land Use Pattern and Travel Behavior on Waterborne Transport
Authors: Yupho Sauvanithi , Jomsueb Tienwanan , Pujinda Panit
Published: March 2017

Before the emergence of paved road and highways, waterways and waterborne transport once were the heart of transportation that provided mobility and flexibility for Thais. Cities relied on waterways for commerce, socio-economic opportunity, and leisure until the advent of motorway development. Many canals were covered over and turned into streets, while cities were converted to inland development, resulting in the decline of the role of waterways. However, at present, there are four waterways that are making a comeback due to the ever-congested traffic on roads. Currently, water transit accounts for only three percent of transport modes (Trip Generation Model, 2011), but the key waterways provide direct and efficient travel to central Bangkok. Although it is an escape from inland-traffic, waterborne transport itself has various limitations on catchment area that requires different travel behavior.Keywords: Waterborne Transport; Travel Behavior; Land Use Pattern; BangkokISSN: 2398-4287© 2017.

The Application of Discourse Analysis to English Reading Teaching in Chinese Universities—What is the Focus?
Authors: Nie Yanwei
Published: March 2017

Reading is a primary avenue of language input and the spread of knowledge. Some EFL learners focus on vocabulary and grammar, but ignore the broader relationship between words, sentences and paragraphs in reading. Due to this, it is of great necessity to introduce discourse analysis to English reading teaching because of its potential to improve students’ discourse awareness and reading comprehension. While discourse analysis covers three aspects, structure of discourse, cohesion and coherence, and background information and context, this paper aimed to identify the ideal focus of discourse-based English reading teaching and to uncover pedagogical differences between English majors and non-English majors in Chinese universities. The research findings show that Chinese students have a good sense of discourse in general, and the main difference between English majors and non-English majors is that English majors are more inclined to grasp the main idea by analyzing the structure of discourse. The pedagogical implication is that if discourse-based reading teaching is applied for non-English major students, it should focus more on reading strategies related to the structure of discourse.

The purposes of the research are: To determine differences in learning outcomes of students with learning model Cooperative Group Investigation and Direct Instruction teaching model, to determine differences in learning outcomes student's mastery of the material that has low prerequisite Physics and Physics prerequisite mastery high, to determine the interaction between Models of Learning and the level of mastery learning model materials physics prerequisite in improving student learning outcomes Physics. The sample in this study conducted in a cluster random sampling of two classes, where the first class as a class experiment applied learning models Cooperative Group Investigation as a class and the second class of controls implemented Direct Instruction model. The instrument is used in this study is physics learning outcomes tests in narrative form as many as 10 questions and materials physics prerequisite mastery tests in narrative form as many as 7 questions that have been declared valid and reliable. The results were found: there are differences in physical students learning outcomes are taught by Cooperative Group Investigation learning model and Direct Instruction teaching model. There is a difference in student's learning outcomes that have a low mastery of prerequisite Physics and Physics prerequisite mastery of the material is high. There is interaction between learning models and the level of student mastery of the material prerequisites of Physics in influencing the physical students learning outcomes.
