UV, first, second and third derivative spectrophotometric methods have been developed for the determination of ezetimibe in pharmaceutical formulation. The solutions of standard and sample were prepared in methanol. For the first method, UV spectrophotometry, the quantitative determination of the drug was carried at 233 nm and the linearity range was found to be 6-16 mug/ml. For the first, seco...

Silicon (Si) nanostructures that exhibit a significantly low reflectance in ultraviolet (UV) and visible light wavelength regions are fabricated using a hydrogen etching process. The fabricated Si nanostructures have aperiodic subwavelength structures with pyramid-like morphologies. The detailed morphologies of the nanostructures can be controlled by changing the etching condition. The nanostru...

The application of ultraviolet absorption detector (UV) and circular dichroism (CD) detectors in series in HPLC systems has been increased in recent years. In this work, an effective method to determine the enantiomer concentration on line in chiral drugs was explored. Ibuprofen (IBP) racemate was applied. The total concentration and concentration difference of S-(+)-IBP and R-(-)-IBP were obta...

An (a, d)-edge-antimagic total labeling of a graph G with p vertices and q edges is a bijection f from the set of all vertices and edges to the set of positive integers {1, 2, 3, . . . , p + q} such that all the edge-weights w(uv) = f(u) + f(v) + f(uv);uv ∈ E(G), form an arithmetic progression starting from a and having common difference d. An (a, d)-edgeantimagic total labeling is called a sup...

Apotransferrin (apo Tf)  in 0.1 M N-(2hydroxyethyl)piperazine-N2-ethanesulfanic acid at 25 ˚C  and pH 7.4 has been titrated with acidic solution of Tb3+. The binding of Tb3+ at  the two specific metal-binding sites of transferrin was followed from the changes in the difference UV spectra at 245 nm. The molar absorptivity per binding site for Tb3+...

A (p, q)-graph G is (a, d)-edge antimagic total if there exists a bijection f : V (G) ∪ E(G) → {1, 2, . . . , p + q} such that the edge weights Λ(uv) = f(u) + f(uv) + f(v), uv ∈ E(G) form an arithmetic progression with first term a and common difference d. It is said to be a super (a, d)-edge antimagic total if the vertex labels are {1, 2, . . . , p} and the edge labels are {p+ 1, p+ 2, . . . ,...

A graph G of order p and size q is called (a, d)-edge-antimagic total if there exists a bijective function f : V (G) ∪ E(G) → {1, 2, . . . , p + q} such that the edge-weights w(uv) = f(u) + f(v) + f(uv), uv ∈ E(G), form an arithmetic sequence with first term a and common difference d. The graph G is said to be super (a, d)-edge-antimagic total if the vertex labels are 1, 2, . . . , p. In this p...

UV intensity near the AOS and OSF sites in northern Chile was measured with handheld UVA and UVB radiometers and was compared with that taken at Socorro AOC, Nobeyama, and Mitaka. Typical UVA opacity was about 0.4 at Pampa La Bola near the AOS site, about 0.6 both at San Pedro de Atacama near the OSF site and at Nobeyama, and about 0.7 at Mitaka (best conditions), respectively. The UVA intensit...

OBJECTIVE To compare the therapeutic efficacy of narrowband (TL-01) UV-B phototherapy vs photochemotherapy (psoralen-UV-A [PUVA]) in patients with chronic plaque-type psoriasis. DESIGN Open, nonrandomized, intraindividually controlled paired comparison study. SETTING Phototherapeutic unit in a university hospital. PATIENTS Twenty-five patients with chronic plaque-type psoriasis. INTERVE...
