Multimedia technology in banking

Banking in the global village becomes reality with multimedia communication systems that connect far flung regions and integrate all their various marketplaces. International banks in particular face the major challenge of achieving the right balance between global and local. They must identify local customers' requirements and satisfy them by exploiting the expertise and technology available worldwide     

The choose-get-keep model of psychiatric rehabilitation: A synopsis of recent studies.

Objective: Comprehensive review of studies using the choose-get-keep (CGK) process model of psychiatric rehabilitation. Also, other studies are identified that have demonstrated methodologies useful in future research on the CGK model. Intervention Model: The CGK process is conceptualized as the phases through which people with psychiatric disabilities proceed as they engage in psychiatric rehabilitation. Conclusion: The CGK model is a potentially useful psychiatric rehabilitation intervention that can be implemented in a variety of service settings and that focuses on the activities of the practitioner and the service recipient. The CGK model warrants further empirical study to examine its effectiveness. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Acidic hydrolysis of plasmalogens followed by high-performance liquid chromatography

A simple, quantitative method for determining the plasmalogen content of small samples is reported here. The method uses the different susceptibility to acid-catalyzed hydrolysis of the alkyl, alkenyl and acyl linkages to separate the plasmalogen subclass from the other two non-labile subclasses. Hydrolysis of plasmenylethanolamine and plasmenylcholine was complete after 4 and 1 min of acid treatment, respectively. The acid-catalyzed hydrolysis did not alter the phospholipid fatty acid composition, making this method useful for fatty acid compositional analysis of the plasmalogen subclass. High-performance liquid chromatography was used for separations, and phospholipids were quantitated by assay of lipid phosphorus or by direct quantitation of peak area. Using this method, small amounts (10 nmol) of ethanolamine glycerophospholipid and choline glycerophospholipid are subjected to acid-catalyzed hydrolysis and subsequent separation of the resulting lysocompounds obtained from plasmalogens from the more acid-stable alkylacyl and diacyl glycerophospholipid fractions. Our values for plasmalogens from commercial preparations of choline and ethanolamine glycerophospholipids agree with literature values. The usefulness of the method is demonstrated for small glycerophospholipid samples that are equivalent to samples from cultured neural cells.     

Technological and spoiling characteristics of the yeast microflora isolated from Bella Di Cerignola table olives

This study focused to investigate the technological significance and the spoiling impact of diverse yeast strains, isolated from 'Bella di Cerignola' Italian table olives. Sixty-four isolates (belonging mainly to the species Candida famata and C. guilliermondii ) were studied to assess their growth at different temperatures (15, 25 and 37 °C), pHs (4.0, 5.0 and 9.5) and NaCl concentrations (0–10.0%) in lab medium. Their pectolytic, xylanolytic, lipolytic and catalase activities were also evaluated. Most of the yeasts showed a moderate pectolytic activity and were able to grow at pH 9.5 after 120 h of incubation. Salt and temperature were the most important environmental variables affecting yeast growth, which could exert a strong selective pressure on yeast population. Candida guilliermondii appeared more resistant to high salt concentrations, whereas C. famata was able to grow at 15 °C.     

Effects of practice on character-classification performance.

Presented a character-classification task to 7 male college students under conditions of limited practice consistent with the characterization of memory search as a high-speed internal exhaustive serial comparison process having an average rate of 25-30 symbols/sec. Ss each performed under 3 positive set size conditions on each of 30 sessions. Results indicate that throughout sessions (a) the relationship between set size and response latency remained linear; (b) equality of slopes obtained from positive and negative trials was maintained; and (c) the estimate of scanning rate was stable, and its absolute value almost identical to previous values obtained with limited practice.

Correlates of household smoking bans among Chinese Americans.

No population-based data are available on the degree to which Chinese Americans have adopted smoke-free household policies and whether these policies are effective in reducing environmental tobacco smoke (ETS) exposure. The present study examines the prevalence of smoke-free home rules among Chinese Americans living in New York City, describes predictors of adopting full smoking bans in the home, and explores the association between household smoking restrictions and ETS exposure at home. In-person interviews using a comprehensive household-based survey were conducted with 2,537 adults aged 18-74 years. Interviews were conducted in Mandarin, Cantonese, and other Chinese dialects. A total of 66% of respondents reported that smoking was not allowed inside the home, 22% reported a partial ban on smoking in the home, and 12% reported no smoking ban. Among current smokers, 38% reported a full household smoking ban. Current smoking status was the strongest predictor of less restrictive household smoking policies. Knowledge of the dangers of ETS, support of smoke-free air legislation, years in the United States, gender, income, and marital status also were associated with household smoking bans. Those living with a total household smoking ban were significantly less likely to report 30-day exposure to ETS than were those living in homes with a partial ban or no ban (7% vs. 68% and 73%, respectively). In homes of smokers and nonsmokers alike, exposure to ETS remains high. Smoke-free home rules and interventions among smokers and nonsmokers to raise awareness of the dangers of ETS have the potential to significantly reduce exposure to household ETS among this immigrant population.     

Studies on the mechanical degradation of cellulose

The mechanical degradation by high-speed stirring of cellulose in dilute n-butanol suspensions was investigated on six different samples with degrees of polymerization (DP) between 300 and 7500. The degrees of polymerization were determined viscosimetrically in CuEn (copper ethylendiamine complex) at different times of mechanical action. The distributions of the DP were measured on the polymer-analogous nitrates by size exclusion chromatography (HPSEC) in THF. The investigations reveal that only high-molecular-weight cellulose undergoes degradation, whereas celluloses with a starting DP₀ < 3000 remain undegraded. In the case of degradation the decrease of the DP with time is exponential, reaching a “limiting” DP (DP_∞) of about 3200 which does not diminish further. The narrowing with degradation time of the distributions of DP of the degraded samples allows to assume that the bonds splitting by the action of mechanical forces are the so-called “weak links” present in high-molecular-weight cellulose. The course of the nonuniformity U with decreasing DP, could be confirmed by mathematical derivation of the relationship between U and the degree of degradation DP₀/DP_t, considering the scission of only “weak links”.     

The effect of temperature on the pattern of torpor in a marsupial hibernator

The feeling that life has had no meaning is an impediment to a peaceful death. Life review enables a person to identify events that have been of worth and so enhances self-esteem. This approach has been extended and formalized by establishing a biographer service to compile oral and written biographies of patients who may be expected to benefit from such a re-examination of their lives. The service is now also being offered to patients whose disability precludes most other forms of activity. The value of biography as therapy is considered and it is concluded that it has much to offer in the circumstances described.     

Nanostructured electrochemical sensors based on functionalized nanoporous silica for voltammetric analysis of lead, mercury, and copper

We have successfully developed electrochemical sensors based on functionalized nanostructured materials for voltammetric analysis of toxic metal ions. Glycinylurea self-assembled monolayers on mesoporous silica (Gly-UR SAMMS) were incorporated in carbon paste electrodes for the detection of toxic metal ions such as lead, copper, and mercury based on adsorptive stripping voltammetry (AdSV). The electrochemical sensor yields a linear response at a low ppb level of Pb2+ (i.e., 2.5-50 ppb) after a 2-min preconcentration period, with reproducible measurements (%RSD = 3.5, N = 6) and an excellent detection limit (1 ppb). By exploiting the interfacial functionality of Gly-UR SAMMS, the sensor is selective for the target species, does not require the use of a mercury film, and can be easily regenerated in dilute acid solution. The rigid, open, parallel pore structure, combined with suitable interfacial chemistry of SAMMS, also results in fast analysis times (2-3 min). The nanostructured SAMMS materials enable the development of miniature sensing devices that are compact and low cost, have low energy consumption, and are easily integrated into field-deployable units.
