Tire-chip reinforced foundation as liquefaction countermeasure for residential buildings

To prevent vibration-induced and liquefaction-induced damage to residential buildings during earthquakes, a low-cost technique has been developed and described here. It utilizes a mixture of tire chips and gravel as the horizontal reinforcing inclusion under the foundation of residential houses. The horizontal reinforcing inclusion refers to a layer of tire chips and gravel which is placed horizontally beneath the foundation. This mixture of tire chips and gravel provides sufficient bearing capacity to the foundation. In this research, a series of small-scale 1 g model shaking table tests was performed to evaluate the effectiveness of the technique. In addition, cyclic undrained triaxial tests were performed to evaluate the liquefaction susceptibility of tire chip-gravel mixtures. The results of the model tests indicated that when the thickness of the reinforced layer is 10 cm (2 m in prototype) and the gravel fraction (percentage by volume of gravel in the mixture) is 50%, the technique yields the best performance. The element tests also indicated that the gravel fraction plays an important role. A gravel fraction of 50–60% by volume was found to be the best mixing percentage, at which the rise in excess pore water pressure could be significantly restrained without compromising the stiffness of the reinforcing inclusion.

Characterization of the functioning of the Motril–Salobreña coastal aquifer (SE Spain) through the use of environmental tracers

Environmental tracers were used to characterize the origin and determine the age of the groundwater in the Motril–Salobrena aquifer (south-eastern Spain). The stable isotope concentrations (δ18O/δ2H), compared to the results obtained in previous studies, indicate that most of the recharge during the sampling period was from irrigation return flow and the carbonate Escalate aquifer. The combined dating of 3H, 3He, 4He, 85Kr, and 39Ar allowed establishing the presence of modern water throughout the aquifer, although with different mixing percentages. Thus, there is a large zone characterized by a fluvial domain with 100% young waters ( 170 years), and the percentage of young water is reduced (22.5%). This is explained by the greater distance that groundwater travels (aquifer thicknesses is over 250 m) and the lower permeability of the aquifer in the deeper sectors.

Application of mathematical models and microfluidics in the analysis of saliva mixing with antiseptic solutions

Background/Aim: Human saliva offers many advantages over blood-based biochemical assays, therefore, becomes the biological fluid of interest. Once antiseptic solutions react with saliva, both fluids undergo significant changes of their biophysical properties, consequently, those changes have an impact on their principal function. Material and Methods: In this study, saliva was collected and mixed with 0,1% chlorhexidine digluconate solution, fluoride mouthwash, zinc-hydroxyapatite solution and CPP-ACP paste. Microfluidic PVC/Green tape chips within the experimental setup were used to simulate solution mixing. The chip had 2 inlets and 1 outlet, and channel was designed in Y shape without any obstacles. The inlet channels were set at a 60° angle. The channel width was 600 µm and the diameter of inlets and outlet was 2 mm. For better visualization, blue food coloring was added to the saliva. The procedure was recorded with digital USB microscope camera and afterwards the percentage of mixing was obtained by MATLAB programming language. Results: Obtained results show incomplete mixing of all the solutions with saliva. The value of mixed liquid, when mixing 0,1% chlorhexidine digluconate solution with saliva was 51,11%. In case of medium concentration fluoride mouthwash, result was 84,37%. Zinc hydroxyapatite solution obtained result of 85,24%, and the fourth tested solution, CPP-ACP paste, 83,89%. Conclusions: Analyzed mouthwashes exhibit specific, non uniform behavior during mixing with saliva. Microfluidic setups could be efficiently used in simulating real clinical conditions in laboratory settings. Image processing mathematical models are applicable, accurate and useful in determination of the interaction of saliva with commonly used antiseptic solutions.

Characterisitics Examination of Bentonite Mortar with Replacement of Cement

The experimental investigation on alternate concrete from aged volcanic ash or hydrated aluminium silicate was done by partially replacing bentonite with OPC. Bentonites consist of the fundamental elements of cement like silica, magnesium and calcium. The total assets of bentonite in the country are about 531 million tons bulk of the resource in Tamil Nadu.The partial replacement of bentonite with cement leads to reduction of cement content in concrete mix and furthermore decreases the transfer and contamination issues. Cylinders and cubes were casted and tested for the 7th, 14th and 28th days respectively.10, 20, 30, 40 and 50% replacement of bentonite with cement are done. Slump test are also done to study the workability characteristics of replacement concrete according to Indian standards. Finally the estimation was computed for all the partial replacement of concrete samples of bentonite according to percentage of mix.

Passive mixing rate of trapped squeezed nanodroplets—A time scale analysis

The elegance of digital microfluidics is in incorporating high quantities of manipulated micro and nanodroplets on-chip, each of which can be considered a small-volume carrier of various chemical and biological reagents. Therefore, the analysis of on-demand manipulation of these micro and nanocarriers is extremely important in developing an optimized lab on a chip. In this work, passive coalescence and mixing between two trapped, squeezed nanodroplets inside a closed microfluidic device was investigated. The droplets are composed of glycerol dyed in blue and red, dispersed inside oleic acid as the carrier oil. A microwell with a circular cross section was fabricated on the top wall of the microchannels to trap the first droplet for increasing the mixing precision and minimizing the viscous shear stress imposed on the droplets from the channel walls. The energy minimization theory was used to develop a parametric study for this trapping technique and to choose the optimum design parameters for droplet trapping in terms of efficiency. Image processing was performed on the snapshots of the trapped glycerol nanodroplets during mixing. Growth in passive mixing percentage was demonstrated to be asymptotical and was formulated with an empirical equation of exponential form as a function of the passive mixing relaxation time. The required time for the passive mixing of a glycerol droplet pair was measured considering various thresholds for the final standard deviation of the gray intensity indices. This finding was of the order of magnitude of the diffusive mixing time scale and physically consistent with the Stokes flow regime.

Production of sensitive gas sensors using CuO/SnO2 nanoparticles

Metal oxide nanoparticles, such as CuO and SnO2, are outstanding systems for H2S gas sensing in air. In this work, those nanoparticles were deposited with different mixing percentages on substrates to form percolating networks of nanoparticles. Electrical electrodes were deposited on the nanoparticles’ films to investigate their gas sensing response against H2 and H2S, and their electrical characteristics. The sensor devices based on CuO–SnO2 nanoparticles revealed enhanced sensing characteristics against H2S with a sensitivity of 10 ppm. The enhanced sensing characteristics could be attributed to the formation of PN-junctions among CuO and SnO2 nanoparticles. The reasonable production cost (due to simple structure and cheap used materials), low power consumption ( ~ 1 µW for H2S at room temperature), high sensitivity, high response, and reasonable response time of the present sensors qualify them for practical implementation in portable gas sensing devices with enhanced characteristics.

Tracing and quantifying contributions of end members to karst water at a coalfield in southwest China

Karst water, which provides 25% of the world's drinking water, is especially vulnerable to anthropogenic contamination. Such is the case in southwestern China with trace element pollution in important karst aquifers. Approximately 20% of the total study area consisted of abandoned mine tailings with elevated concentrations of Fe, S, Mn, As, Cu, and Cr. Acid mine drainage (AMD) water originating from pyrite oxidation of the tailings was characterized by low pH and high concentrations of Fe, SO42−, and As. Concentrations of Fe, Mn, Al, SO42−, As, Cd, and Pb in spring water in wet and dry seasons were greater than WHO and USEPA drinking water guidelines. Based on the results of mineral characterizations, hydrogeochemistry, and isotopic compositions (δ34SSO4, δ18OSO4, and δ18OH2O), the chemistry of AMD water was primarily controlled by pyrite oxidation, river water by atmospheric precipitation, and spring water by carbonate rock dissolution and mixing with river and AMD waters. A three-end-member mixing model identified the contributions of these different end members to spring water quality. Although AMD water was characterized by the lowest mixing percentages during the wet (14.1%) and dry (26.9%) seasons, it played a very important role in degrading spring water quality. Based on these findings, an investigation strategy was developed for illuminating seasonal water quality and potential remediation methods corresponding to the contaminants in the spring water are also proposed to manage this seriously polluted karst system. Results could benefit remediation planning for these distinctively complex and vulnerable systems in other regions of the world.

CFD analysis and RSM-based design optimization of novel grooved micromixers with obstructions

Computational fluids dynamics (CFD) and response surface methodology (RSM) are used to optimize grooved micromixers with obstructions. The starting geometry is inspired by the work of Wang and co-workers (Wang et al., 2012) which consists of a Y-type micromixer with cylindrical grooves adjoining to the main straight channel. Obstructions are added to the grooved micromixers. To observe influences of obstruction shape, simulations are carried out for three types of geometric shapes: circular, square and diamond. The effects of obstruction dimension (OD) and offset (OF) in the range of 60–120 µm and 0–30 µm, respectively, are investigated on the percentage of mixing (φ), pressure drop (Δp) and mixing energy cost (mec). The numerical experiments are designed based on a five-level CCD to develop statistical models for the optimization procedure. Results show that φ monotonically increases with the increase of OD in all values of OF for all obstruction shapes. Same trend is observed with increase in the offset. Moreover, results reveale that Δp and mec increase with the increase of OD at almost all offset values for all shapes of obstructions. Conversely, the pressure drop and the mixing energy cost reduce as OF increases. Finally, φ, Δp and mec are considered as the objective functions to numerically optimize the performance of grooved micromixers with obstructions. Overall desirability values of 0.796, 0.834 and 0.760 are found for micromixers with circular, diamond-shaped and square obstructions, respectively. For circular obstructions, the obtained optimal value of dimension is 110.75 µm, while the respective value for the diamond-shaped obstructions is 116.98 µm and for the square obstructions is 116.88. In addition, the constant value of 30 µm is predicted for the optimum offset for all obstructed micromixers.

RENEWABLE ENERGY AND POLICY DEVELOPMENT IN MALAYSIA

Research Highlights This paper aims to assess the current progress of RE in this country and identify the impact of business sustainability idea towards RE policy development. The extensive review presented in this work offers a useful reference for policy makers, corporate managers and researchers who have vested interest in business sustainability and renewable energy related studies. ___________________________________________________________________________ Research Objectives The objectives of this study is to explore the evolving concept of business sustainability towards environmental concern and to identify the impact of business sustainability idea towards Malaysia’s policy development on RE deployment. Methodology This is conceptual paper where the authors tend to make the analysis by exploring particular theories on business sustainability, renewable energy (RE), and the engagement of RE activities on Malaysia policy development. Results All energy sources have some impact and benefit on our environment. For instance, renewable energy (RE) is energy resource that naturally replenished over time and always can be generated such as solar, wind and hydro energy. However, if the rate of use exceeds the rate of renewal, gradually it will become unsustainable. Thus, to have a sustainable energy which defined as energy production that can last for the foreseeable future is crucial and become main focus of recent national policies, strategies and development plan as of many countries. Malaysia energy consumption still heavily depended on the non- renewable energies (RE) such as fossil fuel and natural gases. Unfortunately, the use of the non-RE is unsustainable and can contribute adversely towards the environment and economic performance of a country. Renewable energy is brought to play as it is believed sustainable and has the potential to thrive in infinitely competitive market of contemporary business nowadays. Therefore, in 2009, the government of Malaysia has announced a National Renewable Energy Policy and Action Plan (NREPAP) as part of their commitment to accelerate the growth of RE as an alternatives energy sources for the coming years. Moving onwards, a strong policy is needed to tackle the challenges in meeting the demand, energy security and also the affordability of energy pricing. Thus, in energy security dimension, perhaps the government should put attention on renewable energy by engaging more on the alternative mechanism to deploy RE capacity through program such as Large-Scale Solar PV, Net Metering as at current practices and also other new initiative like green certificates. The exploration on new RE resource such as wind, geothermal, ocean thermal energy conversion (OTEC) also could assist in build up a new opportunity to enlarge the share of renewable energy mix percentage and ensure the future energy security (UNDP, 2007) Findings The energy industry is changing fast and in multiple directions. It is also regularly known as the catalyst for development in a country. Realizing the importance of energy as a vital dimension in economic and social development, the government of Malaysia has been continuously reviewing its energy policy and practices to ensure long-term sustainability, reliability and security of energy supply (Mohamed & Lee, 2006). The private sector even the communities should also be more corporate in social responsibilities and make compromises for instance by participating in green programs and accepting longer payback periods in RE projects. Nevertheless, continuous efforts and strong support from the societies are vital to ensure RE development can reach its maximum potential. This effort is also supported by (Dincer, 2000) and (Wutenhagen, Wolsink, & Buer, 2007) where they are stressed that increases the public awareness and acceptance on RE, it is as the initial step to make the sustainable energy program successful. This is done through the media, professional organizations, public and government channels. In conclusion, since there is still insufficient insight to critically reasoning the RE development in aspect of business and sustainability, the paper insists to contributes more to the research on energy policies enhancement in Malaysia particularly. This could be a challenge on governing agenda that involves a series of tradeoffs, market players, organizations and companies (Oliveira, 2018) and these efforts are important to ensure the future success of the RE development in Malaysia.

An Investigation into the Suitability of GGBS and OPC as Low Percentage Single-Component Binders for the Stabilisation and Solidification of Harbour Dredge Material Mildly Contaminated with Metals

The occurrence of contaminated materials encountered during harbour dredging is becoming increasingly problematic for harbour and port authorities. The risks to human health, wildlife and port infrastructure of exposure to such contaminants necessitates the removal or containment of such risks. As with contaminated terrestrial sites the solidification and stabilization (S/S) of this material has been proven to be an effective alternative to disposing of contaminants off-site, typically via dumping at sea or in a landfill. Research, to date, on S/S has been focused on heavily contaminated sediments in large industrial ports. However, with tightening environmental regulations, the limits of acceptable contamination are generally decreasing. This means the number of port dredging projects requiring contaminant remediation is increasing. There is now a need to examine the effectiveness of S/S on harbour sites that are mildly contaminated from both an environmental and project feasibility viewpoint. To that end, this study examines the effectiveness of various S/S mix percentages of ordinary Portland cement (OPC) and ground granulated blast furnace slag (GGBS) in retarding the leaching of contaminants from a mildly contaminated harbour site.

Comparison of Engineering Geology Properties Natural Granite with Artificial Types

Understanding of the geological characteristics of artificial stone is of particular importance. Appearance, size and dimensions, specification of particle surface and minerals forming aggregates are among the characteristics of rock materials that affect the homogeneous and cladding environment. Volume variations, water absorption, resistance to atmospheric agents and wear resistance are the most fundamental features of engineering stone in artificial stone. In this research, to investigate and compare the resistance properties (Uniaxial Compression, Brazilian, Point Load, Ultra Sonic) and the physical properties of artificial stones made with additives (polyester resin, vinyl ester resin, glass fiber and aggregate type) with three granite samples, we will cover the Alamut granite, Takab granite and Nehbandan granite. The results of the study show that the glass of fiber glass samples compared to non-woven glass made of resin and aggregates, has more 15% of tensile strength, 14% of uni - axial compressive strength and 12% of the point load index. As well as, resistance of samples made with a leaden resin is 1.64 times more than polyester resin specimens. Based on this study, the mixing plan and percentage ratio combination is the most important principle in the strength and strength of artificial stone

From result of research can be concluded that semekin big percentage of mixing of used oil hence influence to smoke thickness in Isuzu Panther diesel motor. The used oil mixture of 5% to 40% of the resulting smoke thickness is still within the threshold of the exhaust emissions in accordance with Regulation of the Ministry of Environment No. 5 of 2006 which is smoke thickness below 70%.

Preparation and studying of some properties of polymer composites reinforced with natural and artificial fibers

This work concerns the thermal and sound insulation as well as the mechanical properties of polymer matrix composite reinforced with glass fibers. These fibers may have dangerous effect during handling, for example the glass fibers might cause some damage to the eyes, lungs and even skin. For this reason the present work, investigates the behavior of polymer composite reinforced with natural fibers (Plant fibers) as replacement to glass fibers. Unsaturated Polyester resin was used as matrix material reinforced with two types of fibers, one of them is artificial (Glass fibers) and the other type is natural (Jute, Fronds Palm and Reed Fibers) by hand lay-up technique. All fibers are untreated with any chemical solvent. The Percentage of mixing was (90 wt. %) of the matrix while the weight fraction of each type of fibers was fixed (10 wt. %). The mechanical tests included impact and flexural strength tests. The results showed that the impact strength and flexural strength of the composites reinforced with Jute fibers is higher than that of Glass fibers and other natural fibers. The coefficients of thermal conductivity of the composites were measured by Lee's disc apparatus, the results show that the thermal insulation of the composite reinforced with jute fibers is higher than that of glass fibers and other natural fibers. The acoustic insulation of the composites reinforced with Jute fibers showed excellent result in insulation compared with glass fibers and other natural fibers.

Proposed Cone Calorimeter for Woven Carpet

It is necessary to achieve the best specifications in carpets that provide safety to human health in establishments and buildings. This can be achieved by reducing the emissions of toxic gases from combustion via controlling the carpets composition. This research presents a study on carpets behavior when burning samples with different mixing specifications to determine the combustion products by conducting a test using cone Calorimeter to determine the effect of different structures of the carpet on combustion products. The study includes the effect of both the quality of the material used and their different densities and thicknesses. The research provides an analysis of carpet combustion products from different emissions, such as the amount of carbon monoxide CO, the amount of carbon dioxide CO2, smoke density, heat of combustion, and the heat released rate. It is clear that the rate of heat released is uneven in samples with different percentages of mixing. The samples with higher mixing percentage of synthetic fibers give lower temperature while the samples with higher wool percentage give higher temperature. The temperature of combustion increases gradually with the increase of the percentage of wool while the density of the smoke decreases which achieves the required safety of carpets. In addition to this, the research proves the increase of both CO and CO2 as the percentage of synthetic fibers in products which confirms the necessity to avoid the adverse effects of these emissions on human health.

Exploitation of Waste Materials for Repairing Concrete

Epoxy and polymers played a significant role in the world of construction and repair in the past few decades. The major problem in using epoxy for construction repair is its high cost. The current study aims at confronting this problem, and attempting decrease cost by adding waste materials without affecting it’s properties.Window glass and porcelain tile waste were chosen to add to the epoxy at different percentages (10, 20, 30, and 40 %) to create composites that could be used as new repairing materials. The experiment will attempt to find out the suitable percentage of mixing. Such percentage is not used when bonding the concrete to decrease the cost of concrete repairing. Accordingly, the new composites were tests for compression and bond strength to measure the adhesion strength. The final results showed a general improvement in the properties of the new composite when adding glass and porcelains, yet the porcelains results were much better than glass as filler with epoxy, which achieved the main objective of the current work in finding a developed and better repair material used for cracks and construction with a less cost.

Mapping Crop Calendar Events and Phenology-Related Metrics at the Parcel Level by Object-Based Image Analysis (OBIA) of MODIS-NDVI Time-Series: A Case Study in Central California

Remote sensing technology allows monitoring the progress of vegetation and crop phenology in large regions. Seasonal vegetation trends are commonly estimated from high temporal resolution but coarse spatial resolution satellite imagery, e.g., from MODIS-NDVI (Moderate Resolution Imaging Spectroradiometer—Normalized Difference Vegetation Index) time-series, which has usually limited their application to scenarios with few land uses or crops covering areas larger than actual parcel sizes. As an alternative, this paper proposes a general and robust procedure to map crop phenology at the level of individual crop parcels, and validates its feasibility in a complex and diverse cropland area located in central California. A first calibration phase consisted of evaluating the three curve-fitting models implemented in the TIMESAT software (i.e., asymmetric Gaussian (AG), double logistic (DL), and adaptive Savitzky–Golay (SG) filtering) and reporting the model and its settings that best adjusted to the MODIS-NDVI profile of each crop studied. Next, based on the selected crop-specific models and with a crop map previously obtained from ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer) multi-temporal images, the procedure mapped four crop calendar events (i.e., start, end, middle, and length of the season) and five phenology-related metrics (i.e., base, maximum, amplitude, derivatives, and integrals of the NDVI values) of the study region by object-based image analysis (OBIA) of the MODIS-NDVI time-series. To mitigate the impact of mixed pixels, the OBIA procedure was designed to automatically apply a restrictive criterion based on the coverage of MODIS-NDVI pixels in each crop parcel: (1) using only the MODIS-NDVI pixels that were placed 100% within each crop parcel (i.e., “pure” pixels); or (2) if no “pure” pixels exist in any crop parcel, using only pixels with coverage percentages greater than 50%, and in such cases, reporting the mixing percentage in the output file. The calibration phase showed that the performance of the SG filtering was superior in most crops, with the exception of rice, while the AG model was intermediate in all of the cases. Differences between the dates of the start and end of the season that were observed in 120 ground-truth fields and the ones estimated by the crop-specific models were in a range of 11 days (for the corn fields) and 22 days (for the vineyard fields) on average. The OBIA procedure was also validated in 240 independent parcels with “pure” MODIS-NDVI pixels, reporting 89% and 82% of accuracy when mapping the start and end of the season, respectively. Our results revealed different growth patterns of the studied crops, especially of the crop calendar events of herbaceous (i.e., corn, rice, sunflower, and tomato) and woody crops (i.e., almond, walnut, and vineyard), of the NDVI derivatives of rice and the other studied herbaceous crops, and of the NDVI integrals of vineyard and the other studied woody crops. The resulting maps and tables provide valuable geospatial information for every parcel over time with several applications in cropland management, irrigation scheduling, and ecosystem modeling.
