Wind is one of the cleanest and cheapest renewable energies. One of the wind energy production technologies is use of small wind turbines installed in urban areas. However, installing these turbines in urban areas is associated with problems such as low wind speed and turbulence but if installed in the wrong location, their generated electricity is zero. In this study for the use of wind energy...

Suppose M is a maximal ideal of a commutative integral domain R and that some power Mn of M is finitely generated. We show that M is finitely generated in each of the following cases: (i) M is of height one, (ii) R is integrally closed and htM = 2, (iii) R = K[X; S̃] is a monoid domain over a field K, where S̃ = S ∪ {0} is a cancellative torsion-free monoid such that ⋂∞ m=1 mS = ∅, and M is the m...
Object To study the outcomes of GnRHa on final adult height in Chinese idiopathic central precocious puberty (ICPP) girls and the involved factor(s) that can predict height gain. Methods We conducted a retrospective analysis on 10 years of data obtained from three clinical hospitals from January 2005 to March 2015, and 101 girls with ICPP, who received GnRHa therapy for more than six months a...
Varying the substrate temperature T(s) from 285 to 353 K, both the aggregation behavior of Ag atoms and the preferred structures of the atomic Ag islands on silicone oil surfaces are investigated. After deposition, the deposited Ag atoms form isolated islands with a preferred height. Our observations reveal that, as T(s) increases, the preferred island height increases from 20.0 to 33.0 nm, whi...
Background and purpose: Severe early childhood caries (S-ECC) are amongst the major problems of oral health in children. The purpose of this study was to determine any relationship between S-ECC and body mass index (BMI) in children (2-4 years of age). Materials and methods: In this case-control study, 300 S-EEC infected and 300 S-ECC free children were randomly selected from Tehran kinderga...
We show that for every homomorphism from A to a finite semigroup S there exists a factorization forest of height at most 3 |S|−1. Furthermore, we show that for every non-trivial group, this bound is tight. For aperiodic semigroups, we give an improved upper bound of 2 |S| and we show that for every n ≥ 2 there exists an aperiodic semigroup S with n elements which reaches this bound.
Ocean wave height is one of the critical factors to decide efficiency ocean energy conversion system. Usually, only when resonate occurs between (ocean speed in vertical direction) and system, can from into electric be maximized. Therefore, this paper proposes two predication methods predict future 1.5–2.5 s. Firstly, data fitting real achieved by polynomial method, which beneficial height. Sec...
in this research, a cold model of internally circulating fluidized bed is investigated. the aim is to find the effects of some of the operating parameters on the performance of the reactor. experiments were carried out in a glass column (30 mm i.d. and 25 cm height) with a centrally located draft tube (11 mm i.d. and 5 or 7 cm height). the bed was loaded with white silica particles (dp = 0.15 -...
We quantified the effect of stand age and tree species composition on canopy transpiration ( E C ) by analysing transpiration per unit leaf area ( E L ) and canopy stomatal conductance ( G S ) for boreal trees comprising a five stand wildfire chronosequence. A total of 196 sap flux sensors were used on 90 trees consisting of Betula papyrifera Marsh (paper birch; present in the youngest stand), ...
