The Department of Highways (DOHs), Thailand, designed and constructed a 6m high reinforced earth embankment near Highway No.11 Phitsanulok-Uttaradit in Thailand. Two types of reinforced earth embank-ment were constructed; on one side, bags of soil were used to construct a Reinforced Steep Slope (RSS) with a 70 degree sloping face and on the other side, a Mechanically Stabilized Earth Wall (MSEW) was constructed with a vertical concrete panel as a facing. The test embankment was 18m long and 15m wide at the top. Three types of polymeric geogrid reinforcements were installed in the reinforced steep slope (RSS) facing and two …

For growth in a closed environment, which is indicative of the situation in laboratory experiments, autonomous ODE models do not necessarily capture the dynamics under investigation. The importance and impact of a closed environment arise when the question under examination relates, for example, to the number of the surviving microbes, such as in a study of the spoilage and contamination of food, the gene silencing activity of fungi or the production of a chemical compound by bacteria or fungi. Autonomous ODE models are inappropriate as they assume that only the current size of the population controls the growth-decay dynamics. This …
Lower Bounds On The Kobayashi Metric Near A Point Of Infinite Type, Tran Vu Khanh
Lower Bounds On The Kobayashi Metric Near A Point Of Infinite Type, Tran Vu Khanh
Faculty of Engineering and Information Sciences - Papers: Part A
2015 Mathematica Josephina, Inc. Under a potential-theoretical hypothesis named f-property which holds for all pseudoconvex domains of finite type and many examples of infinite type, we give a new method for constructing a family of bumping functions and hence plurisubharmonic peak functions with good estimates. The rate of lower bounds on the Kobayashi metric follows by the estimates of peak functions. The application to the continuous extendibility of proper holomorphic maps is given.
Fatigue Properties Of Intact Sandstone In Pre And Post-Failure And Its Implication To Vibratory Rock Cutting, M N. Badge, Shivakumar Karekal
Fatigue Properties Of Intact Sandstone In Pre And Post-Failure And Its Implication To Vibratory Rock Cutting, M N. Badge, Shivakumar Karekal
Faculty of Engineering and Information Sciences - Papers: Part A
The pre-and post-failure fatigue properties of intact sandstone subjected to uni-axial cyclical loading in the laboratory is presented with its possible implication to vibratory rock cutting. The fatigue results subjected to sinusoidal, ramp and square waveforms at cyclic loading frequency of 5 Hz and peak amplitude of 0.05 mm is discussed herewith. It is observed that fatigue behaviour is a function of the dynamic energy of the load and the shape of the waveform. From the presented results, the practical significance of the behaviour of rock and rock masses within the excavation systems subjected to cyclic loads, especially in the …

The increase of antibiotic resistant microorganisms urged the development and synthesis of novel antimicrobial biomaterials to be employed in a broad range of applications, ranging from food packaging to medical devices. This work describes the production and characterization of a protein-based electrospun fibrous membranes bearing antimicrobial properties. Its composition is exclusively comprised of proteins, with fish gelatine as structural matrix and bovine lactoferrin (bLF) as the active antimicrobial agent. The bLF bactericidal effect was determined against clinical isolates of Escherichia coli and Staphylococcus aureus through microdilution assays. Two distinctive methods were used to incorporate bLF into the fish gelatine nanofibres: …
The Role Of Pyrimidine And Water As Underlying Molecular Constituents For Describing Radiation Damage In Living Tissue: A Comparative Study, Martina C. Fuss, L Ellis-Gibbings, Darryl B. Jones, M J. Brunger, Francisco Blanco, A Muñoz, Paulo Limao-Vieira, Gustavo Garcia

Water is often used as the medium for characterizing the effects of radiation on living tissue. However, in this study, charged-particle track simulations are employed to quantify the induced physicochemical and potential biological implications when a primary ionising particle with energy 10 keV strikes a medium made up entirely of water or pyrimidine. Note that pyrimidine was chosen as the DNA/RNA bases cytosine, thymine, and uracil can be considered pyrimidine derivatives. This study aims to assess the influence of the choice of medium on the charged-particle transport, and identify how appropriate it is to use water as the default medium …

Although biofeedback systems have been used to improve balance with success, they were confined to hospital training applications. Little attempt has been made to investigate the use of in-shoe plantar force measurement and wireless technology to turn hospital training biofeedback systems into wearable devices. This research developed a wearable biofeedback system which detects body sway by analyzing the plantar force and provides users with the corresponding haptic cues. The effects of this system were evaluated in thirty young and elderly subjects with simulated reduced foot sensation. Subjects performed a Romberg test under three conditions: (1) no socks, system turned-off; (2) …
