Polysulfone/Cellulose Acetate Phthalate/Polyvinylpyrrolidone (PSf/CAP/PVP) Blend Membranes: Effect of Evaporation Time on Blend Membrane Characteristics

Recently, researchers proved that the evaporation time during the membrane fabrication process has a significant effect on the characteristics and performance of membranes. In this study, flat sheet asymmetric polysulfone/cellulose acetate phthalate/polyvinylpyrrolidone (PSf/CAP/PVP) blend membranes were fabricated at different evaporation time in the range of 0–20 s to investigate the effect of the evaporation time on characteristics of the blend membranes. The PSf/CAP/PVP blend membranes were characterized in terms of water content, porosity, pure water flux and permeability coefficient. The results showed that an increase of evaporation time from 0 to 20 s has resulted in decreasing of water content and porosity of the PSf/CAP/PVP blend membranes. The permeation water flux of the blend membrane was decreased with the increment of evaporation time. This indicated that an increase of evaporation time would lead to a decrease of the membrane permeability coefficient and hence increased the membrane resistance to permeation of water through the membranes

Bat Ecotourism Potential At Wind Cave Nature Reserve, Sarawak Through Bat Conservation Study

The study conducts roost site mapping, roost sites preferences, bat assemblage and bat acoustic call at the Wind Cave Nature Reserve (WCNR) from 2013 to 2015. The area lack information on bats and the existing information has not been updated for quite some time. The study utilizes the non-consumptive method that uses observation, data logger and the wildlife acoustic song meter to collect data. The data obtained are important as baseline data for future management and conservation of the bats species at the WCNR. This information also provides additional interesting information to tourists. This paper is a collection of the ecological studies of cave-dwelling bats that have been conducted at the WCNR. The findings from the study such as species list; and a map that show the location of the bats and their roost sites preferences can help increase awareness towards the conservation of bats at WCNR to promote better ecotourism benefit

Process capability of high speed micro end-milling of Inconel 718 with minimum quantity lubrication

The demand for micro-parts is expected to grow and micro-machining has been shown to be a viable manufacturing process to produce these products. These micro-products may be produced from hard-to-machine materials such as superalloys under little or no metal cutting fluids to reduce machining cost or drawbacks associated with health and environment. This project aims to investigate the capability of micro end-milling process of Inconel 718 with minimum quantity lubrication (MQL). Microtools DT-110 multi-process micro machine was used to machine 10 micro-channels with MQL and 10 more under dry condition while maintaining the same machining parameters. The width of the micro-channels was measured using digital microscope and used to determine the process capability indices, Cp and Cpk. QI Macros SPC for Excel was used to analyze the resultant machining data. The results indicated that micro end-milling process of Inconel 718 was not capable under both MQL and dry cutting conditions as indicated by the Cp values of less than 1.0. However, the use of MQL helped the process to be more stable and capable. Results obtained showed that the process variation was greatly reduced by using MQL in micro end-milling of Inconel 718

Thermoluminescence properties of the Cu-doped lithium potassium borate glass

Characteristics of lithium potassium borate glasses with various copper concentrations are reported. The glasses were prepared by the melt quenching method and irradiated with photons to doses in the 0.5-4.0. Gy range. Glowing curves, dose response curves, reproducibility of the response, dose threshold, thermal fading and optical bleaching were studied

An integrated model to design earthquake resistant structures

Selection of the material and design of earthquake resistance structures are an important issue today. Many people die every year due to inappropriate design and selection of the materials. There are several software to be used for structural design of buildings, however they just design the structure based on some limited standards. There is a need to develop a computer-based earthquake resistant design model to integrate the current market’s software with different design standards of different countries. The objective of this study is to propose a model to integrate the local structural design standards/codes with available market’s programs. To achieve this objective, Microsoft Excel was used as the core of the model to be integrated with one of the market’s program. Then, the model was developed in three phases. To test the model, the Iranian design standard (Code 2800) was used to design a 7-story apartment. The results show that the model can be fully integrated with those market’s programs which support Microsoft Excel. The result of Phase 1 of the model is useful to select the optimum selection of the material while Phase 2 and 3 contribute to design of the earthquake resistant structure

Bioconcrete strength, durability, permeability, recycling and effects on human health: a review

Concrete has become as one of the common material in the construction sector, which makes it of great interest to the researchers in pursuit for the production of concrete with better properties. This is mainly because the existing concrete has several limitations in terms of strength, ductility, durability and resistance to cracking. To overcome this problem with the use of bioconcrete, it can self-heal and also posses other value added features like high durability, increased strength and less water absorption capacity. Even though several studies to date have been focused on the development of bioconcrete but the aspects of advantage and disadvantages using bioconcrete has not been discussed so far. The objective of this study is to review the positive and negative impacts of bioconcrete application in the aspect of strength, durability, permeability, recycling and its effects on human health. A systematic review has been used to review some of the relevant and recently published works in this area. The diverse advantages has been mainly covered like; increasing the concrete durability, increasing the concrete strength, increasing of concrete permeability, and ability of biological concrete for recycling. The effect of biological concrete on human health as one of the main disadvantages using bioconcrete has also been covered. The findings of this paper can be considered significant for the stakeholders in the construction sector, as well as the engineers in gaining insight towards the potential use of biological concrete in the field of construction, considering both the merits and demerits of using biological concrete. As a conclusion, the research paper highlights several advantages and disadvantages of bioconcrete that helps to predict the future commercial application of bioconcrete in the construction industry

Voids characteristic of hot mix asphalt containing waste cooking oil

Pure bitumen production through crude oil petroleum refining process is not desirable in road pavement application. The asphalt binder exhibits insufficient properties for pavement construction and need to be modified with various additives. In this study, the effect of untreated and treated waste cooking oil (WCO) on voids properties of hot mix asphalt was evaluated. A 5% of WCO (by weight of binder) was selected and replaced into the modified binder before being mixed with the aggregates in asphalt mixture. The voids characteristic of hot mix asphalt was determined based on Marshall Mix design test. Five different content of bitumen i.e. 4%, 4.5%, 5%, 5.5% and 6% was chosen on the basis of min and max value as required by Malaysia public work department. Test results show that the voids filled with bitumen and density was increase as the bitumen content increases from 4% to 6% for untreated and treated WCO mixes. Furthermore, the result also indicates that the void in total mix was linearly decreased when the bitumen content increased from 4% to 6%
