This study investigated the influence of nanoclay on the impact damage resistance of glass fiber-epoxy composites under high velocity ice impact loading. Addition of 0.5 wt. % nanoclay into epoxy was shown to improve damage resistance compared to composite plates having no nanoclay platelet. The glass fiber-epoxy composites containing nanoclay brought about substantial improvement in ice impact...

The influence of nanoclay on the impact damage resistance of glass fiber–epoxy composites has been investigated using high-velocity repeated ice impact tests. The incorporation of nanoclay into epoxy enhances the impact resistance of the composites. The impact of ice is a realistic scenario for composite structures such as aircraft fuselages, wing skins and fan blades and it is not a completely...

The Antarctic contribution to sea-level rise has long been uncertain. While regional variability in ice dynamics has been revealed, a picture of mass changes throughout the continental ice sheet is lacking. Here, we use satellite radar altimetry to measure the elevation change of 72% of the grounded ice sheet during the period 1992-2003. Depending on the density of the snow giving rise to the o...

It is now acknowledged that certain foods may affect mood and behavior. Recently, the food industry has seen a rise in foods containing beverages such as green tea cake, ice-cream, coffee biscuits as per the traditional chocolate as a food and cocoa beverage. Green tea has been suggested to exert numerous health properties, including anxiolytic properties (Vignes et. al. 2006), as does cocoa (i...

BACKGROUND Consumption of low fat dairy foods may decrease the risk of obesity, type 2 diabetes, hypertension, and all cardiovascular risk factors linked with increased probability of cognitive impairment. AIM To examine associations between dairy intake and self-reported cognitive function and psychological well-being, and to test the novel hypothesis that dairy consumption may benefit cogni...

IMPORTANCE Given the importance of developing healthy eating patterns during early childhood, policies to improve the elementary school food and beverage environments are critical. OBJECTIVE To examine the association between district and state policy and/or law requirements regarding competitive food and beverages and public elementary school availability of foods and beverages high in fats,...

carotenoids are the main pigments of tomato, of which 93% is lycopene. lycopene has desirable physiological effects in human sush as cancer prevention. recent years, because of harmful side effects of synthetic colouring agents used in food products, employing of natural food colouring agents has become very important. in this research firstly, solvent extraction method was used for tomato caro...
