chrysanthemum (dendranthema grandiflorum (ramat.) kitamura cv. pattriot) is one of the most important and marketable cut flowers in the world. however, a relatively limited vase life reduces its marketability. the aim of this study was to evaluate the efficacy of salicylic acid (sa) and citric acid (ca) in extending the vase life of chrysanthemum flowers. therefore, a factorial experiment based...

Ferulic acid is an important phenolic antioxidant found in or added to diet supplements, beverages, and cosmetic creams. Two designs of paper-based platforms for the fast, simple and inexpensive evaluation of ferulic acid contents in food and pharmaceutical cosmetics were evaluated. The first, a paper-based electrochemical device, was developed for ferulic acid detection in uncomplicated matrix...

Anion [CMo(N[R]Ar)(3)](-) (R = C(CD(3))(2)CH(3) or (t)Bu, Ar = 3,5-C(6)H(3)Me(2)) containing one-coordinate carbon as a terminal substituent and related molecules have been studied by single-crystal X-ray crystallography, solution and solid-state (13)C NMR spectroscopy, and density functional theory (DFT) calculations. Chemical reactivity patterns for [CMo(N[R]Ar)(3)](-) have been investigated,...

Abstract 1-(Phenylamino-1,3,4-thiadiazol-5-yl)-3-phenyl-3-oxopropan (PTPO) was selected as the investigated material for studying protection performance mild steel in 1 mol L-1 hydrochloric acid solution. The inhibitor assessed using weight loss measurements complemented with morphological analytical techniques and density functional theory (DFT) modelling. PTPO demonstrated significant inhibit...

The antioxidant activity of Annona squamosa (A. squamosa) leaf was carried out using methanol extract and fractionated namely n-hexane, ethyl acetate residue. performed the 1-diphenyl-2-Pycrilhydrazil (DPPH) method. test residue yielded IC50 6.87, 169.99, 31.55 44.75 ppm. fraction with ppm by column chromatography silica gel G60 as stationary phase n-hexane: mobile phase. results obtained 181 f...

The study was conducted to evaluate the effect of vitamin E and zinc supplementation on energy metabolites, lipid peroxidation, and milk production in peripartum Sahiwal cows. For this, thirty-two pregnant dry Sahiwal cows were selected at sixty days prepartum and divided into four groups viz control, T1, T2, and T3 of eight each. Group T1 were supplemented with zinc at 60 ppm/d/cow, group T2 w...

OBJECTIVES The ototoxicity of occupational exposure to toluene plus noise was investigated in a longitudinal study in rotogravure printing and existing findings in the literature were evaluated. MATERIAL AND METHODS The study comprised four repeated examinations during 5 years and started with 333 male workers. Lifetime weighted average exposures (LWAE) to toluene and noise were determined fr...

A novel conductometric hydrogen sulfide (H2S) sensor was fabricated by AC dielectrophoretic assembly of amino acid mediated grown gold nanoparticles across microfabricated gold electrodes. Excellent sensing performance toward hydrogen sulfide, including a sensitivity of 29.84% ppm , a lower detection limit in the sub-ppm level, the upper detection limit of 2 ppm, and a response time of<20 s for...

We evaluated the airway irritation of isoprene, isoprene/ozone, and isoprene/ozone/nitrogen dioxide mixtures using a mouse bioassay, from which we calculated sensory irritation, bronchial constriction, and pulmonary irritation. We observed significant sensory irritation (approximately 50% reduction of mean respiratory rate) by dynamically exposing the mice, over 30 min, to mixtures of isoprene ...

An experiment was conducted on mungbean (Vigna radiata L.) during three consecutive years of zaid (2016 to 2018) at Agricultural Research Station, Ummedganj, Kota (Rajasthan). The consisted 12 treatment combinations including irrigation regimes (IW/CPE ratio 0.8, 1.0 and 1.2) four fertility amendments along with foliar spray bio-regulator (100 % RDF, 100 RDF + salicylic acid ppm, 125 ppm 150% p...
