| 1 | Is there a relationship between vitamin D with insulin resistance and diabetes mellitus?显示文摘Available data suggest a possible link between abnormalvitamin D level and abnormal glucose homeostasis,two of the most common chronic medical conditions.Both conditions are associated with inflammation,and the exact mechanism for role of either on the other is not well clear.Literature investigating the link between vitamin D and either pre-diabetic states or diabetes is reviewed.Vitamin D deficiency is detrimental to insulin synthesis and secretion in animal and human studies.In humans,it has been shown by majority of observational studies,that vitamin D is positively correlated with insulin sensitivity and its role is mediated both by direct mechanism through the availability of vitamin D receptors in several tissues and indirectly through the changes in calcium levels.Large number of,but not all,variable samples cross sectional human trials have demonstrated an inverse relation between vitamin D status and impaired glucose tolerance,insulin resistance or diabetes.To compliment this conclusively,evidence from intervention studies is critically warranted before we can frankly state that vitamin D plays a role in diabetes prevention or treatment.Absence of both sizable prospective observational trials utilizing 25(OH)D as the main variable and the non-availability of randomized studies specifically designed to assess the effects of vitamin D on pre-diabetes and diabetes states,are the main obstacles to draw solid and conclusive relationships. | Kamal AS Al-Shoumer Thamer M Al-Essa | 2015 | World Journal of Diabetes2015，6，8： | 13 |
| 2 | Mechanical properties of cotton fabric reinforced geopolymer composites at 200-1000℃显示文摘Geopolymer composites containing woven cotton fabric(0-8.3 wt%)were fabricated using the hand lay-up technique,and were exposed to elevated temperatures of 200℃,400℃,600℃,800℃and 1000℃.With an increase in temperature,the geopolymer composites exhibited a reduction in compressive strength,flexural strength and fracture toughness.When heated above 600℃,the composites exhibited a significant reduction in mechanical properties.They also exhibited brittle behavior due to severe degradation of cotton fibres and the creation of additional porosity in the composites.Microstructural images verified the existence of voids and small channels in the composites due to fibre degradation. | Thamer ALOMAYRI Les VICKERS Faiz U.A.SHAIKH It-Meng LOW | 2014 | Journal of Advanced Ceramics2014，3，3： | 4 |
| 3 | Influence of diversion angle on water and sediment flow into diversion channel显示文摘Accumulation of the sediment in the stream of the diversion channels adversely affects its operational systems.Diversion channels are often constructed perpendicular to the main river.In this study,the water flow and sediment transport in the diversion channel with different angles were investigated in an attempt to maximize water discharge and minimize sediment discharge.A physical model with movable bed was used to simulate water and sediment flow with five diversion angles(θ)between(30°-90°).Moreover,three bed width ratios(Br)(the relation between diversion to main channel bed width)between 30%and 50%and five total discharges between(7.25 L/s to 12.25 L/s)were considered for each case of(θ).The results showed,up to 10%,increasing in proportion discharge ratios for 30 and 45 diversion angles compared with 90° diversion angle.The results also showed that the lowest diversion sediment concentration was provided by the(θ)of 30°.Across all scenarios,the average proportion concentration reduction was 64%,compared with 90diversion angle.Closer observation of the diversion system mechanism confirmed that decreased(θ)result in decreased sediment concentrations in the diversion channels.In conclusion,the diversion channel water and sediment discharge could be effectively managed by changing the(θ)to 30° or 45° instead of 90°. | Nashwan Kamalaldeen Alomari Badronnisa Yusuf Thamer Ahmad Mohammad Abdul Halim Ghazali | 2020 | International Journal of Sediment Research2020，35，6： | 4 |
| 4 | Characterisation of mechanical and thermal properties in flax fabric reinforced geopolymer composites显示文摘This paper presents the mechanical and thermal properties of flax fabric reinforced fly ash based geopolymer composites.Geopolymer composites reinforced with 2.4,3.0 and 4.1 wt%woven flax fabric in various layers were fabricated using a hand lay-up technique and tested for mechanical properties such as flexural strength,flexural modulus,compressive strength,hardness,and fracture toughness.All mechanical properties were improved by increasing the flax fibre contents,and showed superior mechanical properties over a pure geopolymer matrix.Fourier transform infrared spectroscopy(FTIR)and scanning electron microscopy(SEM)studies were carried out to evaluate the composition and fracture surfaces of geopolymer and geopolymer/flax composites.The thermal behaviour of composites was studied by thermogravimetric analysis(TGA)and the results showed significant degradation of flax fibres at 300℃. | Hasan ASSAEDI Thamer ALOMAYRI Faiz U.A SHAIKH It-Meng LOW | 2015 | Journal of Advanced Ceramics2015，4，4： | 4 |

| 6 | Broad bandwidth SOA-based multiwavelength laser incorporating a bidirectional Lyot filter显示文摘We demonstrate a broad bandwidth multiwavelength laser based on a bidirectional Lyot filter and a semiconductor optical amplifier with a mechanism of intensity-dependent loss as the flatness agent. A wide bandwidth of a multiwavelength spectrum of 32.9 nm within a 5 dB uniformity is obtained under optimized polarization parameters. For this case, the number of generated lasing lines is 329 with a fixed wavelength separation of 0.1 nm. The power stability of this multiwavelength laser is less than 1.35 dB within 200 min time frame. This shows that the bidirectional Lyot filter provides an alternative option for multiwavelength generation in laser systems. | Abdul Hadi Sulaiman Muhammad Zamzuri Abdul Kadir Nelidya Md Yusoff Noran Azizan Cholan Fairuz Abdullah Ahmad Fauzi Abas Mohammed Thamer Alresheedi Mohd Adzir Mahdi | 2018 | Chinese Optics Letters2018，16，9： | 2 |
| 7 | Rapid and robust slope failure appraisal using aerial photogrammetry and 3D slope stability models显示文摘Slope failures are an inevitable aspect of economic pit slope designs in the mining industry.Large open pit guidelines and industry standards accept up to 30%of benches in open pits to collapse provided that they are controlled and that no personnel are at risk.Rigorous ground control measures including real time monitoring systems at TARP(trigger-action-response-plan)protocols are widely utilized to prevent personnel from being exposed to slope failure risks.Technology and computing capability are rapidly evolving.Aerial photogrammetry techniques using UAV(unmanned aerial vehicle)enable geotechnical engineers and engineering geologists to work faster and more safely by removing themselves from potential line-of-fire near unstable slopes.Slope stability modelling software using limit equilibrium(LE)and finite element(FE)methods in three dimensions(3D)is also becoming more accessible,user-friendly and faster to operate.These key components enable geotechnical engineers to undertake site investigations,develop geotechnical models and assess slope stability faster and in more detail with less exposure to fall of ground hazards in the field.This paper describes the rapid and robust process utilized at BHP Limited for appraising a slope failure at an iron ore mine site in the Pilbara region of Western Australia using a combination of UAV photogrammetry and 3D slope stability models in less than a shift(i.e.less than 12 h). | Neil Bar Michael Kostadinovski Michael Tucker Glen Byng Rully Rachmatullah Arturo Maldonado Markus Pötsch Andreas Gaich Alison McQuillan Thamer Yacoub | 2020 | International Journal of Mining Science and Technology2020，30，5： | 2 |
