Any defects in street trees may cause injuries to human, vehicles and buildings. This research was investigated in the Babol city, Mazandaran province, in the northern state of Iran.Used the perfect inventory methods and measured the diameter at breathe height (DBH), height and hazardous criteria (dead woods, cracks or seams, decay, wound or cankers, root problems, weak branch unions and skew f...

Define the special tree number, denoted $\mathfrak s\mathfrak t$, to be least size of a height $\omega _1$ which is neither special nor has cofinal branch. This cardinal had previously been studied in context fragments $\m

Given a set of rectangles and a rectangular container with a fixed width, called a strip, the twodimensional strip packing problem (2SP) requires all the given rectangles to be placed orthogonally without overlap within the strip so as to minimize the height of the strip. 2SP and its variants have many applications in steel and textile industries, and it has indirect application in scheduling p...

Hierarchical clustering (HC) is one of the most frequently used methods in computational biology in the analysis of high-dimensional genomics data. Given a data set, HC outputs a binary tree leaves of which are the data points and internal nodes represent clusters of various sizes. Normally, a fixed-height cut on the HC tree is chosen, and each contiguous branch of data points below that height...

almond is among some of the most important nut crops requiring improvement in many aspects of its production. to do that, the first step is an evaluation of the genetic diversity of the existing germplasm. towards this end, 56 vigorous almond seedlings were evaluated with recording eight morphological characteristics (trunk diameter, height of main trunk, canopy density, canopy angle, branch nu...

1. Introduction Suppressing some important technical hypotheses for the moment, the project under-taken in this paper is this: Given a tree T of height and cardinality ω 1 , construct (uniformly in T) a subset S T ⊆ ℵ ω 1 +1 such that, if W is an outer model of V having the same ω 1 , ℵ ω 1 , and ℵ ω 1 +1 in which S T has a closed unbounded (club) subset, then T has a cofinal branch in W. Conve...

this experiment was conducted with the objective of evaluating the performance sage (salvia officinalis l.) in different agroecology of ethiopia for morpho-agronomic and chemical traits at wondo genet, hawassa, qoqa and holleta for two years from 2011/2012 to 2012/2013 cropping seasons. data on plant height, branch number/plant, fresh leaf weight/plant, fresh stem weight/plant, above ground bio...
