#waterimpact

The women of today, be it in urban or rural areas finds themselves at the frontline of these impacts more often than before. Now, say if this particular water collection source begins to shrink during harsh, drier months or during a drought, the distance now needed to travel to secure another water source increases significantly. This already strenuous task now becomes psychologically challenging too. The extra effort and time now taken to collect water cuts into other daily activities needed to en-hance her personal wellbeing – resting, studying, entertaining herself, tending to her children and the elderly as and when needed, etc. Giving a voice to them on a common platform with participants from all levels of gov-ernance can allow the sharing of valuable information and prized success stories.

Highspeed impact of small hydrophobic objects can generate several interesting physical phenomena (Rayleigh-Plateau instability leading to pinch of the air cavity, water curtain sealing which leads to Rayleight-Taylor instability). Here, the authors looked at the water entry of a dense millimetric sphere with a highspeed camera. The frames are separated by 1.9 ms. The 1mm radius sphere is coated to be hydrophobic and impact the water at 540cm/s. At the impact a splash forms at the surface and close inward sealing the air cavity which detaches from the surface and sinks with the spheres. The air being lighter than water, on top of the cavity there is water above (a bit like when you flip a glass of water). A Rayleigh-Taylor Instability arises and is clearly visible in a jet like form. In the mean time the  cavity pinches off due to surface tension.  The jet produced by the instability will then meet the end of the broken cavity and generate an under water splash. These events repeat with smaller bubbles. Reference: The water-entry cavity formed by low Bond number impacts,Jeffrey M. Aristoff, Tadd T. Truscott, Alexandra H. Techet and John W. M.

whirlwind of colors by Markus Reugels Via Flickr: What can i say.... Here i like the colors . With such shapes it´s very hard to get smooth forms. Here are chaos . but the Colors and swirling colors ... I love it ;) Strobist Info: ISO 320 F16 1/160 One flash (Vivitar 285 at 1/32) with DIY Softbox behind Frosted glas . Sony @700 With Minolta 100 2.8 Thank you for watching ,commenting and Fav my Pictures ! I appreciate them very much . Regards, Markus
