Every additional oxpecker improved detection distance by 9 m. Rhinos alerted by oxpeckers’ alarm calls never re-oriented in our direction but moved to face downwind. Thus, oxpeckers’ calls communicate only threat proximity, not direction, and rhinos assume the hunter is stalking from downwind. We confirm that oxpeckers guard rhinos and the…[Read more]

All class 1a tumours had high nuclear BAP1 expression and all class 2 had low nuclear BAP1 expression. Fifty percent of the class 1b tumours had low nuclear BAP1 expression. Among the tumours with low nuclear BAP1 expression, 68% developed metastasis, while 9% developed metastasis among high nuclear expression. Fifty-five percent developed…[Read more]

The present study reveals the distribution of terrestrial radionuclides (226Ra, 232Th and 40K) and heavy metals (Cr, Ni, Cu, Zn, Pb, Co) from soil samples of Una, Hamirpur and Kangra districts of Himachal Pradesh (India). The 226Ra, 232Th, 40K activity concentration in the studied region has been varied from 8 to 3593 Bq kg-1; 21-370 Bq kg-116;…[Read more]

A longstanding philosophical premise perceives simplicity as a desirable attribute of scientific theories. One of several raised justifications for this notion is that simple theories are more likely to indicate the true makeup of natural systems. Qualitatively parsimonious hypotheses and theories keep to a minimum the number of different…[Read more]

The uncorrected distance visual acuity (UDVA, photopic and mesopic light conditions) was excellent in both groups with statistically significant better results in the IC-8 goup (logMAR; IC-8 group -0.1 ± 0.07, Symfony group 0.07 ± 0.1, p-value 0.02 (photopic); IC-8 group 0.12 ± 0.09, Symfony group 0.22 ± 0.1, p-value less then 0.01 (mesopic)). Bin…[Read more]
