Narcissus is one of the very popular flowers among Iranians. This flower has a short life. To investigate the increasing of vase life of cut Narcissus, sour orange fruit extract in concentrations of 2.5, 4, 5.5 and 7 ml L-1 and sucrose in concentrations of 3, 4, 5 and 6% were used. In addition, distilled water was used as a control treatment. In this experiment, characters of vase life and perc...

BACKGROUND Right insular cortex is involved in taste discrimination, but its functional organization is still poorly known. In general, sensory cortices represent the spatial prevalence of relevant features for each sensory modality (visual, auditory, somatosensory) in an ordered way across the cortical space. Following this analogy, we hypothesized that primary taste cortex is organized in sim...

Studies have shown that smokers rationalize smoking by self-exempting beliefs. This study explored lay beliefs about smoking in Kelantan, Malaysia, using focus groups among outpatients, medical students and staff, and a questionnaire survey of 193 male smokers. In focus groups, patients said they could do something to make smoking safe. When asked, 'Do you think there are any safe ways to smoke...

Caustic scrubbing is a technology that has been used for the removal of H2S and other acid species from gases in different industries for many years. Improvements in design and control strategies, favorable prices for caustic compared with other non-regenerable H2S scavenging chemicals, and the potential for sales value for the NaHS (sodium bisulfide) product have made caustic scrubbing an econ...

Flow of sour cherry (Prunus cerasus L. cv. Montmorency) gum solutions through a glass capillary was Newtonian for pressure gradients from 0 to 1.8 megapascals per meter, and hydraulic conductance was inversely proportional to solution viscosity in this range. However, flow became plastic at pressure gradients above 1.8 megapascals per meter, resulting in a decrease in solution viscosity. The ma...

PURPOSE The discoloration of acrylic resin denture bases may lead to significant esthetic problems. The aim of this in vitro study was to investigate the effects of frequently consumed drinks on the color changes of fresh and aged, heat-polymerized, conventional acrylic resin. MATERIALS AND METHODS Eighty-four, heat-polymerized acrylic resin specimens (4 mm x 5 mm x 30 mm) were fabricated. Ha...

Sour congee, a traditional fermented cereal gruel, has been consumed for hundreds of years in the western regions of Inner Mongolia in China. The preparation procedure for sour congee could be generalized across different regions. Cereal grains, mainly millet and rice (sometimes blended with a little maize) are soaked with clean water in a pot at room temperature (about 25°C) for 3‒4 days. Duri...

Dispersive liquid-liquid microextraction method (DLLME) combined with high-performance liquid chromatography-ultraviolet detection (HPLC-UV) was used to determine thiamine (B1), nicotinamide (B3) and pyridoxine (B6) in sour cherry juice. This method was rapid, simple and sensitive. Separation was accomplished using a C18 column. The optimum chromatographic conditions were found to be: mobile ph...
