Background & Aims of the Study: Due to the increasing pollution of water resources, tow documented methods: the Heavy metal potential index (HPI) and the Heavy metal evaluation index (HEI) were evaluated for their suitability for contamination monitoring of heavy metals (As, Zn, Pb, Cd and Cu) contamination in groundwater resources of Asadabad Plain during spring and summer in 2012. Material...

For any integer  ‎, ‎a minus  k-dominating function is a‎function  f‎ : ‎V (G)  {-1,0‎, ‎1} satisfying w) for every  vertex v, ‎where N(v) ={u V(G) | uv  E(G)}  and N[v] =N(v)cup {v}. ‎The minimum of ‎the values of  v)‎, ‎taken over all minus‎k-dominating functions f,‎ is called the minus k-domination‎number and is denoted by $gamma_k^-(G)$ ‎. ‎In this paper‎, ‎we ‎introduce the study of minu...

If G = (V, E, σ) is a finite signed graph, a function f : V → {−1, 0, 1} is a minusdominating function (MDF) of G if f(u) +summation over all vertices v∈N(u) of σ(uv)f(v) ≥ 1 for all u ∈ V . In this paper we characterize signed paths and cycles admitting an MDF.

Plasmids pMV158 and pTB913, originating from Streptococcus agalactiae and a thermophilic Bacillus respectively, were sequenced to completion. Both contained a BA3-type minus origin of replication and an RSA-site, believed to constitute a site-specific recombination site. These two regions were more than 99% homologous to the corresponding regions of the Staphylococcus aureus plasmid pUB110. Del...

Observation probability • Probability to observe Yo(fk,tm) given tempo bi and RST mj 1) Compute the Yo(l,tm,bi) corresponding to the assumption bi 2) Select the mj which have a reference tempo Bj close to bi: (abs(log2(bi/Bj))<0.3785 3) Compute the one-minus cosine distance between Yo(l,tm,b) and mj=Yj(l) Template-Based Estimation of Tempo: Using Unsupervised or Supervised Learning to create be...

A thermostatted reaction cuvet, operating under computerized or manual temperature control in the ultraviolet or visible region, is described and evaluated. The cell was designed for use with the automated chemistry system described earlier [Clin. Chem. 19, 1114 (1973)], but can readily be adapted for other applications. The entire 3-ml cuvet assembly warms from ambient temperature to 37 degree...

There was rapid efflux of L-leucine, L-phenylalanine, and alpha-methyl-D-glucoside after infection of Salmonella typhimurium with the clear plaque mutant C1 of phage P22. The efflux was similar to that observed with cyanide or arsenate treatment except that there was partial recovery in the case of phage infection and almost complete recovery under the condition of lysogeny. There was no efflux...

The article contains new information about the locations of rare and spreading species flowering plants in Western Siberia Southern Ural (Kurgan Region, Chelyabinsk Tomsk Republic Altai). Among them, four (Bidens frondosa L., Lappula intermedia (Ledeb.) Popov, Melica altissima Verbascum lychnitis L.) are reported as for three (Aquilegia vulgaris Dianthus barbatus Lepidium sativumL.) Altai, two ...
