“There have been many times I’ve had my judgement and decisions called into question simply because I brought attention to discrimination or something culturally insensitive. As a brand consultant who toe-dips in influencing, I’ve sat at both ends of the table and seen first-hand how race, gender and the intersection of identity impact decisions for brands. Sometimes the subtle ways clients will edit all or most women of color from a creative deck is shocking. I’ve gotten into heated arguments, strained relationships and lost clients because of it. I’ve personally dropped out of influencer campaigns and refunded checks when I’ve felt the brand overall didn’t fight for black people.”—Shiona Turini, stylist/creative consultant
That’s not true. It will melt solder wrapped around a copper tube. Materials with a low resistivity will still heat up, it just takes longer.
It is understandable that using disposable batteries will produce a larger amount of waste product over time, but how much worse/better are the environmental impacts of producing and then eventually discarding a lithium ion pack? It is hard for me to imagine that the waste products involved in the production process and the waste material left in a discarded LiPo battery pack are more environmentally-friendly than those same aspects of alkaline batteries.
Some researchers are experimenting with the formation of CNTs from ethylene. Supported catalysts (Fe, Co, Ni), containing either a single metal or a mixture of metals, seem to induce the growth of isolated SWNTs or SWNT bundles in the ethylene atmosphere. The production of SWNTs, as well as double-walled CNTs (DWNTs), on Mo and Mo-Fe alloy catalysts has also been demonstrated. CVD of carbon within the pores of a thin alumina template (called a membrane) with or without a Ni catalyst has been achieved. Ethylene was used with reaction temperatures of 545°C for Ni-catalyzed CVD, and 900°C for an uncatalyzed process. The resultant carbon nanostructures have open ends, with no caps.
Thank you so much for giving everyone a very special chance to read articles and blog posts from this web site. It is always very sweet and stuffed with a good time for me and my office friends to search your web site more than 3 times a week to read the new secrets you have got. And of course, we are actually astounded with the unbelievable tricks you serve. Selected 2 ideas in this posting are particularly the most effective I’ve ever had.

Hans-Peter Neth – MD of Retecon Machine Tools The excitement of this large exhibition is never ending. The pace at which all manufacturers are developing, upgrading and exhibiting their latest technologies is stimulating and incredible.
Both WK2 and SS2 are fully reusable, Palermo emphasizes: “Reusability is at the heart of dramatically changing the economics of access to space to enable new markets to develop and enterprises to thrive. WK2, as the workhorse of our spaceflight system, is fully reusable and can release multiple SS2s per week.”

have you seen old saltwater resistive dimmers? they used to use them in theaters, basically steel rods in a triangle or inverted v, with the resistance increasing as you lift it out of the water.
