Stock-scion interactions on growth and rubber yield of Hevea brasiliensis Interação porta-enxerto x enxerto sobre vigor e produção de borracha de Hevea brasiliensis

Scientia Agricola, 2007
Rubber tree cultivation [Hevea brasiliensis (Willd. ex Adr. de Juss.) Muell.-Arg.] uses mostly the budding propagation method, however the expected stand uniformity due to the use of vegetative propagation is theoretical, since high variation for yield ...

The Independence Ratio of 4‐Cycle‐Free Planar Graphs

Journal of Graph Theory, EarlyView.
ABSTRACT We prove that every n $n$‐vertex planar graph G $G$ with no triangle sharing an edge with a 4‐cycle has independence ratio n ∕ α ( G ) ≤ 4 − ε $n\unicode{x02215}\alpha (G)\le 4-\varepsilon $ for ε = 1 ∕ 30 $\varepsilon =1\unicode{x02215}30$. This result implies that the same bound holds for 4‐cycle‐free planar graphs and planar graphs with no ...

An entropy based proof of the Moore bound for irregular graphs [PDF]

, 2010
We provide proofs of the following theorems by considering the entropy of random walks: Theorem 1.(Alon, Hoory and Linial) Let G be an undirected simple graph with n vertices, girth g, minimum degree at least 2 and average degree d: Odd girth: If g=2r+1 ...

A lower bound on the order of the largest induced forest in planar graphs with high girth

, 2015
We give here new upper bounds on the size of a smallest feedback vertex set in planar graphs with high girth. In particular, we prove that a planar graph with girth $g$ and size $m$ has a feedback vertex set of size at most $\frac{4m}{3g}$, improving the

Guidelines for replacement of a balloon gastrostomy tube in infants and pediatric patients: The American Society for Parenteral and Enteral Nutrition

Journal of Parenteral and Enteral Nutrition, EarlyView.
Abstract Background Balloon gastrostomy tube (BGT) placements are increasing due to their ability to facilitate care of medically complex children. Management for routine and nonroutine tube replacement, including verification of proper replacement, lacks standardization, varying widely among different institutions and settings.

Near-colorings: non-colorable graphs and NP-completeness [PDF]

, 2013
A graph G is (d_1,..,d_l)-colorable if the vertex set of G can be partitioned into subsets V_1,..,V_l such that the graph G[V_i] induced by the vertices of V_i has maximum degree at most d_i for all 1

Lower preoperative Kellgren–Lawrence grade is associated with improved long‐term survivorship following medial meniscus posterior root repair

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose The purpose of this study was to determine whether there was an association between preoperative Kellgren–Lawrence (KL) grade and long‐term failure rates, reoperation free survival rates, and patient reported outcomes of patients undergoing medial meniscal posterior root repair (MMPRR).
