Worrying about La Niña Floods as We Bake under El Niño Heat

ABSTRACT:

SST anomalies equal to or greater than 0.5 °C in the Niño 3.4 region are indicative of ENSO warm phase or El Niño conditions. Oceanic Niño Index is defined as the SST anomalies over Niño 3.4 averaged over the three months ending with the current month. During an El Niño, when the SST anomaly shifts eastwards, droughts and wildfires occur in Indonesia and Australia while heavy rains, floods, and landslides prevail in Peru. Currently, a strong El Niño which commenced in May 2015 and peaked in January 2016 is weakening as reflected by its SST anomaly pattern over the central and eastern Pacific.

Biopolymer Electrolyte Based Dye-Sensitized Solar Cells (BioPE-DSSC)

ABSTRACT:

In polymer electrolytes, the mechanism of the interaction between polymer and salt can be explained with ion solvation by the polymer. Among synthetic based polymer electrolytes, biopolymer electrolytes have been investigated and drawn great attentions for dye-sensitized solar cell applications. The biopolymer electrolyte based dye-sensitized solar cells can be used for many applications to provide environmentally friendly, low cost and economic solar cells for the society, and help to overcome "Climate Change" issue and reduce pollutants through decrease the chemical processes for the production of synthetization of polymers.

Germanium Flat Fiber Dosimetry Kit

ABSTRACT:

The Ge-FF dosimetry kit can be used to monitor exposure to ionizing radiation in both real times and offline, emitting either a radioluminescent or thermoluminescent signal respectively, which allows the worker to react timely when the radiation dosage levels exceed the allowed dosage. The fibers have been shown to have unsurpassed response towards radiation exposures, including that from UV, X-rays, gamma rays, alpha particles and neutrons, making this fiber materials the basis of an excellent multi-purpose radiation detector. The present development has potentials for application in measuring the actual amount of radiation used at the location of a tumor during radiotherapy; measuring radiation used in diagnostic x-ray clinics; measuring levels of radiation prevalent in the environment, and; measuring radiation levels in outer space from satellite-based facilities.

Innovation in Healthcare OsteoKnee™

ABSTRACT:

OsteoKnee™ is an early detection tool for osteoarthritis and it helps medical staff to observe, and monitor the condition of the symptom of OA in the patient. OsteoKnee™ functions in two modes, namely the pressure mode and the sound mode. It has great potential to be commercialized because there is currently no diagnostic equipment available for OA assessment based on knee sound and knee pressure in the market.

High Impact Publication in CHEMICAL REVIEWS: Superoxide Ions

ABSTRACT:

Due to its significant role in diverse natural processes, O2 importance has been thoroughly characterized. In terms of industrial applications, other generation methods such as chemical and electrochemical methods, photochemical and photocatalytic methods and generation at oxide surfaces are employed. The electrochemical generation of O2- entails the reduction of O2 using an electrolyte with low viscosity, and high O2 solubility. Electrochemical preparation is dubbed as the most convenient method because no by-products are formed, although high purity O2 and lots of energy are needed. Following synthesis according to any of the above methods, detection of the final product in aprotic/protic/ILs media is crucial.

Portable Modular Electrical Discharge Machine (PMEDM) for Micro Application

ABSTRACT:

The advantages of EDM over conventional machining techniques, particularly in relation to the machining of electrically conductive workpieces, have also led to the development of PMEDM. The main distinguishing feature between PMEDM and conventional EDM is the dimension of the plasma channel radius that resulted from the localizing sparking. In view of the above, it would be advantageous to have a portable EDM machine for effecting micro electrical discharge machining at a remote worksite

CAHAYA: 2-Micron Q-switched Fiber Laser

ABSTRACT:

In material processing industry, conventional laser cutting and marking for plastic materials application, additional chemical additives were used to increase laser light absorption at the cutting area. In contrast to commercially available lasers such as gas laser or dye laser, CAHAYA is an all-fibre laser technology. Extra external protective wear such as safety goggle is not required during the laser operation as the laser is "Eye-safe".

mySMART Leg

ABSTRACT:

The successful prosthetic leg users usually are able to wear their legs while carrying out daily activities, especially when they have good control over the prosthetic leg. The novelty of mySMART leg technology is its ability to detect the activities of amputee purely from the socket itself, without using brain signals or electromyography signal, which requires additional placement of delicate electrodes in their day-to-day wearing of their prosthetic leg.

A Dual Function Anti-Vibration System

ABSTRACT:

The damper consists primarily of four rubber pads surrounded by steel plates and is based on compression and tension concept in rubber cubes and shear in rubber pads. To evaluate the performance of Chevron Rubber damper device due to earthquake excitation, a steel frame with pin supports equipped with Chevron rubber damper device is modelled by ABAQUS v6.12.3.
