Currently, CPR includes two techniques.The first is mouth-to-mouth resuscitation, the so-called breath of life. The other is chest compression: pushing down hard on a victim's chest, more than once a second, pressing it down at least an inch and a half before releasing. When did CPR ch...
Chi-square tests confirmed that the MBID and the control group were not significantly different in boy/girl ratio (60.9% boys in MBID group / 66.3% boys in control group,p = 0.29) and in the distribution over the three BART conditions (p = 0.48). Moreover, the three BART co...
Various biotic and abiotic stresses threaten the cultivation of future agricultural crops. Among these stresses, heat stress is a major abiotic stress that substantially reduces agricultural productivity. Many strategies to enhance heat stress tolerance
Of the 90% of Thanksgiving meals that feature some sort of cranberry, I wonder what is the ratio of dishes that use fresh cranberry vs. processed cranberry (canned, jellied, prepared sauces). Joe’s family’s Thanksgiving dinners rely on Ocean Spray jellied cranberry sauce. The tradition is...

closer geographically. Utilizing a 0-20cm to 0-30cm ratio, the study ascertained the depth percentage of the 20-30cm layer and predicted the presence of 137Cs and 210Pb in the bulk sample at that depth. Given the observed 20% 137Cs proportion at 20-30cm depth, the considerable H0 value ...
The majority (78%) of the participants were women, which is in accordance with the general ME/CFS patient population that has a female-to-male ratio ranging from 2:1 to 5:1 [113]. Inclusion of severely affected patients, however, did not seem representative. In general, 10 to 25% of...
