A graph G is well-covered if all its maximal independent sets are of the same cardinality. Assume that a weight function w is defined on its vertices. Then G is w-well-covered if all maximal independent sets are of the same weight. For every graph G, the set of weight functions w such that G is w-well-covered is a vector space. Given an input claw-free graph G, we present an O (

effects of lamb and parents coefficient of inbreeding (ci) on wool weight were studied using 10,868 wool records belonging to 3,244 iran black lambs (1,633 males and 1,611 females) representing 96 rams and 995 ewes collected during 1983-2006 from animal breeding station of abbas abad. year and month of shearing, ci of lamb and dam, sex and birth type had significant affect on wool weight among ...

1. The rate of utilization (k) of labelled thyroxine increased when energy intake, given as standard pig meal, was doubled from 20 to 40 g/kg body-weight per d. When the bulk of food was increased, but not its energy content, the value of k did not change. Ambient temperature was constant throughout the experiment. 2. Groups of pigs were given pig meal at 20 g/kg body-weight, 40 g/kg body-weigh...

this experiment was conducted to evaluate the effects of salt stress on some agro-physiological traits in ten varieties of bread (triticum aestivum l.) and durum (triticum turgidum l.) wheats in seedling stage. a greenhouse experiment was carried out as a split plot experiment based on a completely randomized design with four replications in hydroponic condition. different agronomic and physiol...

the fruit set rate and yield of pear are commonly low due to insufficient pollination, as the species is unattractive to honeybees. to improve honeybee foraging behavior for the pollination of dangshan pear (pyrus bretschneideri cv. dangshansuli), nine methods were used to attract bees. a control treatment of colonies was fed with normal sugar syrup, while six other treatments were fed using su...

An outer-independent double Italian dominating function (OIDIDF)on a graph $G$ with vertex set $V(G)$ is a function$f:V(G)longrightarrow {0,1,2,3}$ such that if $f(v)in{0,1}$ for a vertex $vin V(G)$ then $sum_{uin N[v]}f(u)geq3$,and the set $ {uin V(G)|f(u)=0}$ is independent. The weight ofan OIDIDF $f$ is the value $w(f)=sum_{vin V(G)}f(v)$. Theminimum weight of an OIDIDF on a graph $G$ is cal...

pharaoh cuttlefish (sepia pharaonis) is commercially important and native cephalopods in the persian gulf and oman sea. in 2013, a total of 150 eggs of pharaoh cuttlefish were collected from 20 m depth in about 6 miles south of lengeh port and transferred to the laboratory of mollusks research station in bandar-e lengeh. eggs were incubated in temperature of 27.5±0.5 0c (mean ± sd) and salinity...
