Effect of weed elimination treatments on survival, growth and important pest population of poplars in the nurseries of Safrabasteh research station, Guilan province [PDF]

open access: yesتحقیقات جنگل و صنوبر ایران, 2009
Poplar is a one of the fast growing and prolific species that is used for afforestation programs. Advising agro-technical methods with attention to ecological aspects is one of the effective and important factors in integrated management of pests.

Growth and performance of bare and pot rooted seedlings of Loblolly pine (Pinus taeda L.) after plantation [PDF]

open access: yesتحقیقات جنگل و صنوبر ایران, 2005
Seedling production of P. taeda in plastic bags is economically more expensive than bare-rooted method due to limited space for root development (root rotation) and its negative effects on subsequent seedlings growth and performance at field.

Bounded diameter arboricity [PDF]

open access: yesJournal of Graph Theory, 2018
AbstractWe introduce the notion of bounded diameter arboricity. Specifically, the diameter‐ arboricity of a graph is the minimum number such that the edges of the graph can be partitioned into forests each of whose components has diameter at most . A class of graphs has bounded diameter arboricity if there exists a natural number such that every ...

Survival and growth of 10 broadleaved and needleleaved tree species in Fars Province [PDF]

open access: yesتحقیقات جنگل و صنوبر ایران, 2005
Importance of wood as a basic material in industry, along its broad uses and diverse by-products leads us to change our direction from exploitation of natural forests towards artificial forest plantation.

The Minimum Harmonic Index for Unicyclic Graphs with Given Diameter

open access: yesDiscussiones Mathematicae Graph Theory, 2018
The harmonic index of a graph G is defined as the sum of the weights 2d(u)+d(v)${2 \over {d(u) + d(v)}}$ of all edges uv of G, where d(u) denotes the degree of a vertex u in G.

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

open access: yesFEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...
