introduction: the use of radiopharmaceuticals is a powerful tool in the management of patients with infectious or inflammatory diseases in nuclear medicine. in this study ofloxacin as a second-generation fluoroquinolone is used to design a desired infection imaging agent after labeling with 99mtc via direct labeling. methods: ofloxacin was radiolabeled with 99mtc using different concentrations ...

background: the incorporation of thallium-201 into 8-hydroxyquinoline was targeted for cell labeling due to interesting physical properties and wide availability of this nuclide as a single photon emission computed tomography (spect) radionuclide. materials and methods: thallium-201 (t1/2=3.04 d) in tl+ form was converted to tl3+ cation in presence of o3/6m hcl and di-isopropyl ether, controlle...

in this paper we construct antimagic labelings of the regular complete multipartite graphs and we also extend the construction to some families of regular graphs.

it is essential to make urban spaces usable for a wide range of citizens, including aged people. this study was carried out in sari, the center of mazandaran province, northern iran in 2013 to prioritize five urban parks of the city using fuzzy-ahp method in terms of three pre-defined criteria, including safety, security, and environmental health. firstly, the criteria and alternatives were def...

Progress in science has been marked through the ages by public airing of controversial issues. Indeed, the rewards for innovative progress have included banishment, imprisonment, casting out devils, and even burning at the stake (1). Those who dared to challenge prevailing concepts that matter was composed of four fundamental substances, earth, air, fire, and water (2), and that humors were ele...

Let G be a graph with p vertices and q edges and A = {0, 1, 2, . . . , [q/2]}. A vertex labeling f : V (G) → A induces an edge labeling f∗ defined by f∗(uv) = f(u) + f(v) for all edges uv. For a ∈ A, let vf (a) be the number of vertices v with f(v) = a. A graph G is said to be vertex equitable if there exists a vertex labeling f such that for all a and b in A, |vf (a) − vf (b)| ≤ 1 and the indu...

In this paper we introduce remainder cordial labeling of graphs. Let $G$ be a $(p,q)$ graph. Let $f:V(G)rightarrow {1,2,...,p}$ be a $1-1$ map. For each edge $uv$ assign the label $r$ where $r$ is the remainder when $f(u)$ is divided by $f(v)$ or $f(v)$ is divided by $f(u)$ according as $f(u)geq f(v)$ or $f(v)geq f(u)$. The function$f$ is called a remainder cordial labeling of $G$ if $left| e_{...

Let G be a (p, q) graph. Let f : V (G) → {1, 2, . . . , k} be a map. For each edge uv, assign the label gcd (f(u), f(v)). f is called k-prime cordial labeling of G if |vf (i) − vf (j)| ≤ 1, i, j ∈ {1, 2, . . . , k} and |ef (0) − ef (1)| ≤ 1 where vf (x) denotes the number of vertices labeled with x, ef (1) and ef (0) respectively denote the number of edges labeled with 1 and not labeled with 1....

Environmentally friendly products become increasingly popular. To be considered for purchase, they must (1) sufficiently salient and (2) perceived as environmentally (“green”). The current paper investigates whether implicit (packaging material) explicit (eco-labeling) packaging cues can facilitate such salience greenness perceptions. We conducted a mixed-method, within-subjects experiment usin...
