the influence of melatonin receptor 1a gene on litter size was studied in 150 ewes from zel (n=100) and naeini (n=50) sheep breeds. two restriction fragment length polymorphism (rflp) analyses were done to determine all genotypes occurring by variations at mnli and rsai restriction sites. the m and c were the most frequent alleles in both of these breeds. the mm genotype was predominant in zel ...

copper vanadate nanostructures were prepared via ex-situ precipitation approach in presence of schiff-base ligand (n,n׳ -buthylenebis(acetylacetone iminato)dianion = acacbn) as a new capping agent. the effect of different cu sources and ph on the size, morphology and size distribution of copper vanadate nanostructures was investigated. the as-prepared products were characterized using x-ray dif...

 Let $R$ be a ring‎, ‎and let $n‎, ‎d$ be non-negative integers‎. ‎A right $R$-module $M$ is called $(n‎, ‎d)$-projective if $Ext^{d+1}_R(M‎, ‎A)=0$ for every $n$-copresented right $R$-module $A$‎. ‎$R$ is called right $n$-cocoherent if every $n$-copresented right $R$-module is $(n+1)$-coprese-nted‎, ‎it is called a right co-$(n,d)$-ring if every right $R$-module is $(n‎, ‎d)$-projective‎. ‎$R$...

to evaluate effects of melatonin treatment in combination with progestagen on reproductive performance of ewes during the anestrus period, 60 ewes were used and allocated randomly in two groups during the anoestrous peiod: all ewes synchronize by cidr and receive pmsg (600 iu) on the day of cidrs removal. ewes in group treatment( n=30 ) resived melatonin implants(18 mg) 35 days before inserting...

Magnesium oxide nanoclusters have attracted much attention due to their potential applications to catalysis and novel optoelectronic materials. In the present study, we have studied the electronic and magnetic properties of the stoichiometric magnesium oxide nanoclusters (MgO)n  for n = 2-20. Although the binding energy increases with the size of the cluster, it  re...

Comparator networks for constructing binary heaps of size n are presented which have size O(n log log n) and depth O(log n). A lower bound of n log log n ?O(n) for the size of any heap construction network is also proven, implying that the networks presented are within a constant factor of optimal. We give a tight relation between the leading constants in the size of selection networks and in t...

It is proved that every regular expression of size n can be converted into an equivalent nondeterministic nite automaton (NFA) of size O(n(log n) 2) in polynomial time. The best previous conversions result in NFAs of worst case size (n 2). Moreover, the nonexistence of any linear conversion is proved: we give a language Ln described by a regular expression of size O(n) such that every NFA accep...

Functional data analysis is a relatively new and rapidly growing area of statistics. This is partly due to technological advancements which have made it possible to generate new types of data that are in the form of curves. Because the data are functions, they lie in function spaces, which are of infinite dimension. To analyse functional data, one way, which is widely used, is to employ princip...
