ON THE NUMBER OF PRIMES LESS THAN OR EQUAL x
(3) Z I"—1 log p = x log x + 0{x). r-ix\-pJ Since [x/^>]= [[#]/£], it is clear that (3) then holds for all real x>0. We propose to show in this note that the order of w(x) =the number of primes less than or equal x (a result originally due to Tschebyschef, cf. [l]) may be derived very quickly from (3) as a consequence of a general theorem which has no particular relationship to prime numbers. T...

متن کاملThe Bondage Number of Graphs with Crossing Number Less than Four
The bondage number b(G) of a graph G is the smallest number of edges whose removal results in a graph with domination number greater than the domination number of G. Kang and Yuan [Bondage number of planar graphs. Discrete Math. 222 (2000), 191198] proved b(G) 6 min{8,∆+ 2} for every connected planar graph G, where ∆ is the maximum degree of G. Later Carlson and Develin [On the bondage number o...

Abstract Background: The aim of study was to compare the effect of Kangaroo mother care (KMC) and conventional methods of care (CMC) in low birth weight babies less than 2000 grams. Method: One hundred babies with birth weight less than 2000 grams and without clinical problem were randomized in two groups the intervention group (N=50) who received Kangaroo mother care and the control gr...
متن کاملThe Separation of Chlorine into Isotopes (Isotopic Elements) and the Whole Number Rule for Atomic Weights.
The purpose of this note is to outline a theory elaborated by the author Which appears to afford satisfactory explanation of much of the published data relating to the degradation of carbohydrates by enzyme systems both "in vivo" and "in vitro." Experimental work to test the theory has been in progress for some time' and on completion may necessitate certain modifications. As this is intended t...
