The textural characteristics of three commercial activated carbons, Filtrasorb 400 (F400), Industrial React High Affinity
and Picabiol, commonly used in water treatment, are reinvestigated. Nitrogen physisorption isotherms are determined in the
range P/P
0 = [4 × 10−7–0.998] and processed using BET, αS (Sing), Dubinin–Radushkevich and Density Functional Theory methods. In addition, fractal dimensions are determined by the
Frenkel–Halsey–Hill procedure. Since F400 is often considered as a reference material in studies on the adsorption of solutes
in aqueous solutions, a review of the textural characteristics of this carbon is carried out. The results obtained in this
work using the different methods are consistent and a critical crossed comparison of these results allows discussing the limitations
of the methods used. In particular, the impact of the P/P
0 range considered on S
BET value is examined. In addition, the accuracy of the BET specific surface area is assessed in the light of information from
recent literature. 相似文献

Background
Decreased bone mineral density and osteoporosis in postmenopausal women represents a growing source of physical limitations and financial concerns in our aging population. While appropriate medical treatments such as bisphosphonate drugs and hormone replacement therapy exist, they are associated with serious side effects such as osteonecrosis of the jaw or increased cardiovascular risk. In addition to calcium and vitamin D supplementation, previous studies have demonstrated a beneficial effect of dietary silicon on bone health. This study evaluated the absorption of silicon from bottled artesian aquifer water and its effect on markers of bone metabolism. 相似文献134.

Physicochemical Properties and Eating Qualities of Milled Rice from Different Korean Elite Rice Varieties 总被引:1,自引:0,他引:1
Mi-Young Kang Catherine W. Rico Chae-Eun Kim 《International Journal of Food Properties》2013,16(3):640-653
Physicochemical properties and palatability of rice from six elite varieties in Korea (Chucheongbyeo, Saechucheongbyeo, Mihyangbyeo, Hitomebore, Nampyeongbyeo, and Ilpumbyeo) were analyzed. All samples, which contained 17–18 g/100 g rice starch amylose, belong to low-amylose rice group. Hitomebore variety showed abundant amount of essential amino acids, highest palatability score (82.9), and lowest mineral content. The rice samples contained relatively similar concentrations of saturated (21–24 g/100 g rice) and unsaturated (75–78 g/100 g rice) fatty acids. Mihyangbyeo variety exhibited the highest amount of protein (8.10 g/100 g rice), sugar content, and pasting temperature (82.75°C) and time (3.78 min), but lowest viscosity values. Ribose, rhamnose, and potassium were found to have negative correlations with palatability and breakdown viscosity, indicating that gelatinization characteristics could also be used in evaluating the eating quality of rice. Results of this study could assist plant breeders in developing rice varieties with improved genetic traits and high eating quality. 相似文献

This study examined the relationship of early alliance ruptures and their resolution to process and outcome in a sample of 128 patients randomly assigned to 1 of 3 time-limited psychotherapies for personality disorders: cognitive–behavioral therapy, brief relational therapy, or short-term dynamic psychotherapy. Rupture intensity and resolution were assessed by patient- and therapist-report after each of the first 6 sessions. Results indicated that lower rupture intensity and higher rupture resolution were associated with better ratings of the alliance and session quality. Lower rupture intensity also predicted good outcome on measures of interpersonal functioning, while higher rupture resolution predicted better retention. Patients reported fewer ruptures than did therapists. In addition, fewer ruptures were reported in cognitive–behavioral therapy than in the other treatments.

There are currently increasing requests for psychologists to provide “consultation” services to their peers, other professionals (ex., physicians, social workers, school teachers) or community services (ex., school, community agencies, mental health services, mass-medias). However, so far, there are few empirical works systematically aiming at defining the character of that professional activity and consultation may still be confused with the competency of intervention in the field of clinical psychology. This article aims at defining “consultation” as a specific professional activity, presenting the models of consultation and exploring clinical examples of consultation. Then, practical, ethical and training considerations related to “consultation” activities are discussed and some recommendations are provided, based on available literature.

In order to develop a microbiological baseline of meat produced for domestic consumption in the state of New South Wales, chilled carcases were sampled from 16 abattoirs. Aerobic Plate Counts (APCs) and Escherichia coli counts were obtained from samples taken by sponging sites specified for each species in the Microbiological Guidelines to the Australian meat standard. On beef carcases the mean log10 APC/cm2 was 2.21 and E. coli was detected on 25% of carcases (mean log positives ?0.61/cm2). For sheep carcases corresponding values were 2.4, 53% and log10 -0.06/cm2, respectively. For pig carcases values were 2.81, 63% and log10 -0.23/cm2, respectively. For skin-off goat carcases values were 1.15, 27% and log10 -0.38/cm2, respectively. In the present survey, levels of indicator bacteria on carcases processed via the co-regulatory system operated in Australia were similar to those established in surveys of abattoirs that operate the traditional system overseen by government inspectors. 相似文献

Listeners had to compare, with respect to pitch (frequency), a pure tone (T) to a combination of pure tones presented subsequently (C). The elements of C were either synchronous, and therefore difficult to hear out individually, or asynchronous and therefore easier to hear out individually. In the “present/absent” condition, listeners had to judge if T reappeared in C or not. In the “up/down” condition, the task was to judge if the element of C most similar to T was higher or lower than T. When the elements of C were synchronous, the up/down task was found to be easier than the present/absent task; the converse result was obtained when the elements of C were asynchronous. This provides evidence for a duality of auditory comparisons between tone frequencies: (1) implicit comparisons made by automatic and direction-sensitive “frequency-shift detectors”; (2) explicit comparisons more sensitive to the magnitude of a frequency change than to its direction. Another experiment suggests that although the frequency-shift detectors cannot compare effectively two tones separated by an interfering tone, they are largely insensitive to interfering noise bursts.
