Model-based prognosis for intergranular corrosion

Among the advantages of Aluminium-based alloys for structural use is their corrosion resistance. However, while Aluminium alloys are highly resistant to uniform (general) corrosion, they are much more susceptible to types of localised corrosion, especially intergranular corrosion, which is a localised attack along the grain boundaries which leaves the grains themselves largely unaffected. In order to estimate the progress of such corrosion in a given sample, it is considered possible to generate a numerical model of some sort. While there has been much effort spent in the development of electrochemistry-based models, the use of grey and black-box models remains largely unexplored. One exception to this is the use of Cellular Automata (CA) models which have recently been exploited to model the progression of uniform corrosion. The object of the current paper is to apply the CA methodology to the case of intergranular corrosion. The first phase of the work has been concerned with generating appropriate CA rules which can qualitatively reproduce observed physics, and this work is reported here. A model is proposed which shows qualitative agreement with experimental data on the advance of the corrosion front

Strain Evolution around corrosion pits under fatigue loading using digital image correlation

Localised corrosion plays a dominant role in the failure of components and structures exposed to the conjoint effects of corrosion and fatigue through the mechanism of corrosion fatigue. In general materials show good fatigue resistance when tested in air. However, under the synergistic effect of a corrosive environment and cyclic stress, this fatigue resistance is greatly diminished Please click Additional Files below to see the full abstract

Poket Musafir: a guide for smart muslim travelers

Prayer (solat) is one of the five pillars of the Islamic faith and it has been stated in the hadeeth of Jaabir (may Allah be pleased with him) who said; I heard the Messenger of Allah (peace and blessings of Allah be upon him) say; “Between a man and shirik and kufr there stands his giving up prayer”. In other words, it is prayer that distinguished the believer from the disbeliever. Given the importance for Muslims to perform their five daily prayers even during travel, an android application, Poket Musafir was developed to guide them in performing their obligations. Poket Musafir included in its menu details on rulings regarding Jamak and Qasr (combining and shortening of prayers) during travel, calculation on distance to see whether one is eligible to perform Jamak and Qasr prayers, common Q&A faced by Muslim travellers in performing their prayers. This application also has quizzes, and can be used by school students to help them understand the topic and test their knowledge, on what they have learnt in a more dynamic way instead of static text in the textbook. Poket Musafir was developed using Android Studio, Adobe Photoshop CS6, GNU Image Manipulation Program (GIMP) and Adobe Illustrator

Loop mediated isothermal amplification based detection of equine respiratory pathogens using a portable, smartphone-based setup

New tools are needed to enable rapid detection, identification, and reporting of infectious viral and microbial pathogens in a wide variety of point-of-care applications that impact human and animal health. We report the design, construction, and characterization of a multiplexed platform for multiplexed analysis of disease-specific DNA sequences that utilizes a smartphone camera as the sensor in conjunction with a handheld “cradle” that interfaces the phone with a silicon-based microfluidic chip embedded within a credit card-sized cartridge. Utilizing specific nucleic acid sequences for four equine respiratory pathogens as representative examples, we demonstrate the ability of the system to utilize a single 15 µL droplet of test sample to perform selective positive/negative determination of target sequences, including integrated experimental controls, in approximately 30 minutes. Our approach utilizes loop mediated isothermal amplification (LAMP) reagents pre-deposited into distinct lanes of the microfluidic chip, which, when exposed to target nucleic acid sequences from the test sample, generates fluorescent products that, when excited by appropriately selected light emitting diodes (LEDs) are visualized and automatically analyzed by a software application running on the smartphone microprocessor. The system achieves detection limits comparable to those obtained by laboratory-based methods and instruments. Assay information is combined with information from the cartridge and the patient to populate a cloud-based database for epidemiological reporting of test results

Indoor air quality (IAQ) in preschools and its association with respiratory inflammation among pre-schoolers

Introduction: Children spend most of the time indoors and make them easily exposed to indoor air contaminants. Exposure to poor indoor air quality has led to various health problem especially, respiratory-related illness. This study is intended to determine the relationship between indoor air pollutants exposure and the airway inflammation among children aged 5 to 6 years old in selected preschools from mid-2015 until mid-2016. Methods: Four hours of indoor air quality assessment had been conducted at six preschools in Puchong district (urban area) and six preschools in Hulu Langat district (suburban area) of Selangor. The respiratory inflammation among 120 healthy preschool children had been assessed using non-invasive biomarker of Fractional Exhale Nitric Oxide (FeNO). Meanwhile, respiratory symptoms and information on possible residential air pollutant exposures were obtained from a standardized questionnaire. Results: The indoor air quality measurement demonstrated significant high concentration air pollutants (PM0.1, PM2.5, PM10, VOCs) at the preschools in the urban as compared to preschools in the suburban area(p < 0.05). Besides, PM2.5 was found to be significantly associated with respiratory inflammation (FeNO value) measured (p<0.05). Conclusion: The exposure of PM0.1, PM2.5, and PM10 had increased occurrences of respiratory inflammation and respiratory symptoms among susceptible populations like children

The Adhesive Strength of Epoxy/Sol-Gel Materials Modified by Various Ratio of γ-Al2O3 Nanoparticles

In this study, the use of sol-gel/epoxy adhesive based on the combination of organic and inorganic components within the adhesive matrix have been studied. The combination of different amounts of γ-Al2O3 nano-particles to the adhesive matrix was evaluated. Mild steel specimens were prepared for lap joints, which were cured in an oven at 200°C for 16 hours. The bond strength of the sol-gel/epoxy matrix was investigated using a universal tensile test machine. The presence of Al-OH and/or Si-OH bonds increases causing an increase in the strength of the bulk material. This process is seen through the appearance of an absorption peak shoulder which appears in the range of ~ 1088 to1100 cm-1 which corresponds to Al-O-Si or Si-O-Si. The maximum adhesive strength of composite sol-gel/epoxy adhesive recorded was 23±0.4 MPa. This was obtained when small amounts of γ-Al2O3 nano-particles (4.0 wt%), were incorporated within the matrix. However, as the level of these inorganic materials in the adhesive matrix increased further, the adhesive shear strength gradually decreased. At a high ratio of γ-Al2O3 particles, poor interfacial bonding or adhesion between the filler and the adhesive matrix is recorded. Scanning Electron Microscopy (SEM) is used to investigate the fracture surface with 4.0 wt% γ-Al2O3, the scanning shows a very small distance of cracks, suggesting the material may act as a barrier to crack propagation and thus increases the energy required for fracture
