A method is described for the simultaneous determination of diclobutrazol, flusilazole, flutriafol, hexaconazole, paclobutrazol, and tetraconazole in apple and pear pulps used in baby food at a limit of 0.01 mg/kg. Apple and pear pulp samples are subjected to selective solid-phase microdispersion (SPMD) with SPE-ED Matrix-38 and acetone-cyclohexane, and the extracts are cleaned up on a Florisil...

Nine hundred fifty-one emergency and 997 nonemergency patients seeking endodontic treatment were the basis of this study. Variables of interest were 10 pain descriptors, percussion and palpation tests, causative factors, and paired pulpal and periapical diagnoses. A higher number of patients suffering from symptomatic pulpal conditions sought emergency care. Odds of caries being a causative fac...

In this study, a set of pulps containing different PSA products that were recycled at the Forest Products Laboratory (FPL) pilot plant were analyzed for deposition using the PIRA deposition device at North Carolina State University. The work is part of the United States Postal Service Environmentally Benign Pressure Sensitive Adhesive effort. The deposition device consists of a counter-rotating...

Abstract Non-destructive testing method scanner based image analysis is used for dirt speck measurement for the evaluation of prints deinkability in waste paper recycling process. The measurement of dirt specks number and area and size classes distribution in undenked and deinked pulps are presented. Two image analysis software tools Spec*Scan, Apogee System and Proton in measurements are used....

Changes in the physical properties of pulp during recycling are sometimes reported to be caused by changes in chemical properties offibres. In order to determine the relationship, if any, between physical and chemical properties, a chemical characterization was carried out of several recycled pulps. Measurements of carbohydrates, lignin, crystallinity index, and DP of cellulose were carried out...

We have studied the structural modifications of lignins from sisal and flax during their soda-anthraquinone (AQ) pulping and subsequent totally chlorine-free (TCF) and elementary chlorine-free (ECF) bleaching. For this purpose, residual lignins were isolated from pulps, analyzed by Py-GC/MS, 2D-NMR, and GPC, and their characteristics were compared to the “milled-wood” lignin of the raw material...

The kraft pulps produced from heartwood and sapwood of Eucalyptus globulus at 130 oC, 150 oC, and 170 oC were characterized by wet chemistry (total lignin as sum of Klason and soluble lignin fractions) and pyrolysis (total lignin denoted as py-lignin). The total lignin content obtained with both methods was similar. In the course of delignification, the py-lignin values were higher (by 2 to 5%)...

AIM The study was undertaken to evaluate mineral trioxide aggregate (MTA) clinically and radiographically as a pulpotomy agent in immature permanent teeth whose pulps were exposed by a complicated crown fracture. MATERIALS AND METHODS Thirty incisors with exposed pulps in twenty-nine patients were examined for this retrospective study. According to exclusion criteria, only twenty-seven teeth ...

Peach (Prunus persica L.), being a potential source of bioactive compounds, has been demonstrated to have medicinal benefits. In this study variation of minerals and antioxidant characteristics (total phenolic contents, total flavonoid contents, reducing power, inhibition of peroxidation using linoleic acid system and DPPH free radical scavenging activity) between peel and pulp parts of differe...

Ohmic heating technology is generally used for processing liquids and solid-liquid mixtures (or pumpable foods) in the food industry. In ohmic processing, the product is heated volumetrically by dissipation of electrical current through it. The main advantages of ohmic heating are the rapid processing and relatively uniform heating achieved. In this review, the application and potential of ohmi...
