BACKGROUND Studies have shown that abdominal girth and vertebral column length have high predictive value for spinal spread after administering a dose of plain bupivacaine. we designed a study to identify the specific correlations between abdominal girth, vertebral column length and a 0.5% dosage of plain bupivacaine, which should provide a minimum upper block level (T12) and a suitable upper b...

The objective of the present paper is to study maximum radius r a connected graph order n, minimum degree δ ≥ 2 and girth at least g 4. Erdős, Pach, Pollack Tuza proved that if = 4, is, triangle-free, then ≤ n − + 12, noted up value additive constant, this upper bound tight. In we shall determine exact maximum. For larger values little known. We settle for 6 , 8 prove an every even g, which con...

In this paper, we prove that a linear block code with girth 2( t +1) is -sequential-recovery locally repairable codes (LRCs) locality xmlns:xlink="http://www.w3.org/1999/xlink">r if its parity-check matrix has column weight at least 2 and row most +1. This gives new connection between seque...

Morris and Saxton used the method of containers to bound number n-vertex graphs with m edges containing no ℓ-cycles, hence girth more than ℓ. We consider a generalization r-uniform hypergraphs. The hypergraph H is minimum ℓ ≥ 2 such that there exist distinct vertices v 1 , … hyperedges e i + ∈ for all ≤ Letting N r ( n ) denote hypergraphs larger defining λ = ⌈ − ∕ ⌉ we show which tight when di...
