We explore the connections between the well-studied Aztec Diamond graphs and a new family of graphs called the Half-Hexagons, discovered by Jonathan Novak. In particular, both families of graphs have very simple domino shuffling algorithms, which turn out to be intimately related. This connection allows us to prove an “arctic parabola” theorem for the Half-Hexagons as a corollary of the Arctic ...

For sexual reproduction of Allium hirtifolium, collected bulbs were planted in the field. In order to develop ovary embryo and seed setting, control self-pollination and natural open pollination took placed using honey bees under cages. Ovary development and seed setting of A. hirtifolium extraordinary were affected by pollination and there was a significant difference between mean effect of se...

Pommé et al. published a paper claiming that the 209Po half-life is 20 % higher than the erroneous value of 102 (5) a used for 50 years. Collé and Collé published a critique saying that 'this claim cannot withstand critical scrutiny'. In this work, counterarguments are presented to the critique. The experiment has been continued and a new intermediate half-life value of 122.7 (27) a was obtaine...

over the four decades, a significant decrease has been observed in age-related mortality caused by cardiovascular disease. people in developing countries suffer from cad at a relatively younger age and about half of mi occurs under the age of fifty years. abuse of anabolic steroids is one of the less common causes of atherosclerosis. in this report, a 23-year-old body builder male referred to e...
