Marx sharply criticized the contemplative materialism of the Young Hegelians, viewing "the essence of man" in isolation and abstraction , instead arguing that the nature of man could only be understood in the context of his economic and social relations.  Marx argued that understanding the origins of religious belief were not enough in moving towards its elimination; instead declaring that it was the underlying social and economic structure which gave rise to religious belief and that it was a transformation of this which was a necessary precondition to the elimination of religion. 
Impedance -based single cell analysis systems are commonly known as Coulter counters . They represent a well-established method for counting and sizing virtually any kind of cells and particles. The label-free technology has recently been enhanced by a " lab-on-a-chip " based approach and by applying high frequency alternating current (AC) in the radio frequency range (from 100 kHz to 30 MHz) instead of a static direct current (DC) or low frequency AC field.  This patented technology allows a highly accurate cell analysis and provides additional information like membrane capacitance and viability . The relatively small size and robustness allow battery powered on-site use in the field.
I just had the most horrible experience, which I think I can fix. I painted a few canvasses in a combination of acrylic ink and acrylic paint, both in light application. The background is gesso I tinted myself with acrylic paint. I haven’t touched them in at least two days. So today I tried to apply the soft gel as instructed above, and the paint started coming off. I was applying the gel with a sponge brush so as to minimise strokes. I wasn’t brushing hard against the canvas. I don’t know what the heck I did, or what happened. I hope it’s just a matter of having not let the canvasses sit long enough, but two days seemed plenty to me given the thinness of the paint application.
