We report the basic luminescence properties and the continuous-wave (CW) laser operation of a Pr(3+)-doped KYF(4) single crystal in the Red and Orange spectral regions by using a new pumping scheme. The pump source is an especially developed, compact, slightly tunable and intra-cavity frequency-doubled diode-pumped Nd:YAG laser delivering a CW output power up to about 1.4 W around 469.1 nm. At ...

Purpose This study aims to demonstrate that orange-derived and lemon-derived systems can be used in continuous processes as efficient adsorbents the entrapment of some anionic cationic dyes textile dyeing wastewater effluents. Design/methodology/approach Physically chemically modified orange lemon mesocarps are natural for Basic Blue 3, Yellow 21, Red 18 Green 4 Acid 264, 49 337, all commonly i...

Immediate allergic reactions to orange are rare and immunoglobulin (Ig) E–mediated [1]. We report the case of a 28-year-old man with anaphylaxis induced by fresh orange juice. The reaction was dose-dependent and could only be confi rmed by challenge test, because specifi c IgE to orange was undetectable by skin prick test (SPT) and CAP immunoassay. The patient had experienced identical anaphyla...

Monomeric [Co(II)(hep-H)(H2O)4]SO4 [1]SO4 and [Co(II)(hep-H)2(H2O)2](NO3)2 [2](NO3)2 have been developed from 2-(2-hydroxyethyl)pyridine (hep-H) and CoSO4·7H2O/Co(NO3)2·6H2O, respectively, at 298 K. On exposure to heat (120 °C), the light orange single crystal of [1]SO4 transforms to a pink single crystal corresponding to the neutral sulfato bridged dimeric complex [(Co(II)(hep-H)(H2O)2(μ2-sulf...

BACKGROUND Vitamin D has been added to calcium-fortified orange juice. It is unknown whether vitamin D is as bioavailable from orange juice as it is from supplements. OBJECTIVES The objective was to compare the bioavailability of vitamin D(2) and vitamin D(3) from orange juice with that from vitamin D(2) and vitamin D(3) supplements. A secondary aim was to determine which form of vitamin D is...

Lead forms the complexes with xylenol orange in the basic solution. An adsorptivedifferential pulse stripping method for the determination of lead is proposed. The procedureinvolves an adsorptive accumulation of lead on a hanging mercury drop electrode (HMDE) inthe presence of xylenol orange, followed by reduction of adsorbed lead by voltammetric scanusing differential pulse modulation. The opt...
