Breakthrough data analysis of adsorption of volatile organic compounds on granular activated carbon

Volatile Organic Compounds (VOCs) such as methanol, ethanol, methyl ethyl keton, benzene, n-propanol, toluene, and o-xylene were adsorbed in a laboratory-scale packed-bed adsorber using granular activated carbon (GAC) at 101.3 kPa. The adsorber was operated batchwise to obtain the breakthrough curves of VOCs under the adsorption conditions such as adsorption temperatures (298–323 K), flow rates of nitrogen (60×10−6-150×10−6m3/min), GAC amount of 0.002 kg, and concentration of VOCs (3,000–6,000 ppmv). The adsorption kinetics was obtained by fitting the experimental breakthrough data to the deactivation model, combining the adsorption of VOCs and the deactivation of GAC. The adsorption isotherm, and adsorbed amount and adsorption heat of VOCs were obtained using the breakthrough curve: the former for comparison with the conventional isotherm models, the latter for correlation with the physical properties of VOCs.
Inside “Pandora’s box”

AbstractOBJECTIVE: To explore the attitudes and experiences of abused women to identify characteristics that helped or hindered abuse disclosure to clinicians and to determine how women viewed potential interventions to improve detection and treatment in a medical setting. DESIGN: Focus group data conducted and analyzed with qualitative methodology. SETTING: Three community-based mental health centers and one women’s shelter. PARTICIPANTS: Twenty-one women in group therapy for domestic violence. MAIN RESULTS: Eighteen (86%) of the 21 women had seen their “regular doctor” in the prior year; only 1 in 3 had discussed the abuse with the clinician. The major discussion themes were medical problems that were exacerbated with abuse, lack of ability to access medical care due to abuser interference, emotional attitudes about abuse that acted as barriers to disclosure, clinician characteristics that helped or hindered disclosure, and treatment experiences and preferences. Women described how their medical problems began or worsened during the abusive period. one in three women described how abusers blocked them from receiving medical care. Women reported intense shame about the abuse and described their self-denial of abuse. Women stated they were inclined to discuss abuse if they felt the clinician was perceived to be caring, was easy to talk to, had a protective manner, or if the clinician offered a follow-up visit. There was no consistent clinician gender preference among the women. One in four women had received psychotropic medication for problems associated with abuse. Many feared addiction, or a loss of alertness, increasing their risk for more abuse. CONCLUSIONS: Many abused women experience worsening health and seek medical care; most do not volunteer a history of violence even to their regular clinicians. Many of the barriers to disclosure of abuse could be overcome by a physician’s knowledge of the link between abuse and medical illness, an understanding of the women’s emotions about abuse, and her treatment preferences.
The Effectiveness of an Education Intervention Related to Knowledge Increase Among Adolescents Regarding Dietary Calcium and Prevention of Osteoporosis

THE EFFECTIVENESS OF AN EDUCATIONAL INTERVENTION RELATED TO KNOWLEDGE INCREASE AMONG ADOLESCENTS REGARDING DIETARY CALCIUM AND PREVENTION OF OSTEOPOROSIS By Deborah K. Fast The purpose of this study was to assess the effectiveness of an educational intervention for b*** 1 1 grade adolescents regarding dietary calcium and the prevention of osteoporosis. This was a secondary analysis o f data from a study that used a preexperimental pre-test-posttest; no control group design. Eighty-two boys and 102 girls completed the Healthy Bones Knowledge Questionnaire (HBKQ) as a pretest, received an educational intervention based primarily on dietary calcium intake, then completed the questionnaire again as a posttest. As a group, the students demonstrated a significant increase in correct answers to calcium-related HBKQ items (t = 3.31, p = .001). Further analysis revealed that girls experienced a knowledge increase (t = 2.95, p = .004) while boys did not.
Dual use of VA and non-VA primary care

AbstractOBJECTIVE: To determine how frequently veterans use non-Department of Veterans Affairs (VA) sources of care in addition to primary care provided by the VA and to assess the association of this pattern of “dual use” to patient characteristics and satisfaction with VA care. DESIGN: Cross-sectional telephone survey of randomly selected patients from four VA medical centers. PARTICIPANTS: Of 1,240 eligible veterans, 830 (67%) participated in the survey. MEASUREMENTS AND MAIN RESULTS: Survey data were used to assess whether a veteran reported receiving primary care from both VA and non-VA sources of care, as well as the proportion of all primary care visits made to non-VA providers. Of 577 veterans who reported VA primary care visits, 159 (28%) also reported non-VA primary care visits. Among these dual users the mean proportion of non-VA primary care visits was 0.50. Multivariate analysis revealed that the odds of dual use were reduced for those without insurance (odds ratio [OR] 0.34; 95% confidence interval [CI] 0.18, 0.66) and with less education (OR 0.60; 95% CI 0.38, 0.92), while increased for those not satisfied with VA care (OR 2.40; 95% CI 1.40, 4.13). Among primary care dual users, the proportion of primary care visits made to non-VA providers was decreased for patients with heart disease (p<.05) and patients with alcohol or drug dependence (p<.05). CONCLUSIONS: Primary care dual use was common among these veterans. Those with more education, those with any type of insurance, and those not satisfied with VA care were more likely to be dual users. Non-VA care accounted for approximately half of dual users’ total primary care visits.
Association between Temporomandibular Dysfunction and Depression in People Living with HIV/AIDS

Background: The origin of temporomandibular dysfunction (TMD) is complex and associates with several factors, including emotional states, such as depression, currently considered one of the main etiological factors of TMD. Objective: to measure the prevalence of temporomandibular dysfunction and its association with the degree of depression in people living with HIV/AIDS. Method: cross-sectional, descriptive, exploratory, quantitative study, developed through the application of Fonseca’s instrument for evaluation of TMD and the Beck Depression Inventory (BDI) in people living with HIV/AIDS from the Expert Assistance Service (EAS). For data analysis, one used Fisher's exact test with statistical significance level p<0.05. Results: The study enrolled 32 subjects, of whom the majority had brown color (65.63%), incomplete elementary school (43.75%), was single (56.25%), with income lower than or equal to the minimum wage ( 87.5%), had mild TMD diagnosis (53.13%), associated with mild degree of depression (40.63%). Conclusions: there was a prevalence of Depression and Temporomandibular Dysfunction in the majority of the sample, and a significant association between those two diseases. It is necessary nursing interventions in health education and early detection of the signs and symptoms of those diseases in that population.
Aggregating school based findings to support decision making: Implications for educational leadership

Successful school reform is dependent on the quality of decisions made by educational leaders. In such decision making, educational leaders are charged with using sound research findings as the basis for choosing school reform initiatives. As part of the debate regarding the usability of various evaluative research designs in providing information in support of decision making, randomised field trials (RFT) have been advanced as the only valid way of determining program effectiveness. This paper presents a methodological rationale that would apply multi-level statistical analysis to aggregated, pre-post intervention data readily available from multiple school sites within a multiple baseline design framework to provide educational leaders with a valid alternative to RFT designs. Presented and discussed is an illustrative application of the potential value of such a design, in establishing the effectiveness of a cluster of reading programs in a form, that is directly applicable by educational decision makers considering reform initiatives and involving developmental reading.
Chemical composition and physicochemical properties of squash (Cucurbita moschata) cultivated in Bolivar department (Colombia)

The present work has evaluated the morphological, chemical and physicochemical properties of three components of squash (the peel, pulp and seed). Proximate composition and physicochemical properties of oil were performed according to AOAC procedures. Different morphological characteristics showed considerable similarities among different cultivars from Bolivar department (Colombia). The higher moisture and carbohydrate contents were established in the pulp with 85.34 % and 81.45 %, and the peel with 81.06 % and 79.23 %, respectively. On the other hand, the seeds had higher amounts of oils and proteins with 25.70 % and 52.6, respectively. The Fourier transform infrared spectroscopy (FTIR) spectrum showed relations with the functional groups of the different vegetal parts with their chemical composition. Considering the proximate composition in the different part of squash appear to be quite promising technological and commercial exploitation.
Balassa-Samuelson: Still haven't found what we're looking for?

Despite its strong theoretical position when it comes to explaining inflation in transition economies, the empirical merits of the Balassa-Samuelson (B-S) effect are weak. This paper points to three theory-based contributing factors to these weak findings and offers an alternative approach. First, the short-term focus makes B-S prone to underestimating the magnitude of the productivity growth differential. Second, the conventional demand side CPI based sectoral composition reduces the extent to which the productivity growth differential is passed through to inflation. Third, by ignoring the dependence between the two main B-S components, a second downward bias to the productivity growth pass through comes about. The key to our proposed alternative centres around an endogenous relation between the productivity growth differential and sector sizes. The long-run supply-side approach allows us to capture inflation drivers that conventional B-S fails to incorporate. The paper provides a blueprint for future empirical analysis.
Stakeholder Theory and Marketing: Moving from a Firm-Centric to a Societal Perspective

This essay is inspired by the ideas and research examined in the special section on “Stakeholder Marketing” of the Journal of Public Policy & Marketing in 2010. The authors argue that stakeholder marketing is slowly coalescing with the broader thinking that has occurred in the stakeholder management and ethics literature streams during the past quarter century. However, the predominant view of stakeholders that many marketers advocate is still primarily pragmatic and company centric. The position advanced herein is that stronger forms of stakeholder marketing that reflect more normative, macro/societal, and network-focused orientations are necessary. The authors briefly explain and justify these characteristics in the context of the growing “prosociety” and “proenvironment” perspectives—orientations that are also in keeping with the public policy focus of this journal. Under the “hard form” of stakeholder theory, which the authors endorse, marketing managers must realize that serving stakeholders sometimes requires sacrificing maximum profits to mitigate outcomes that would inflict major damage on other stakeholders, especially society.
Phytochemical Screening, Total Phenolics, Flavonoids Contents, Total Antioxidant Capacity and Antifungal Activity of Cymbopogon giganteus Extracts from Burkina Faso

Extracts obtained from roots, stems, leaves and flowers of Cymbopogon giganteus using hexane, dichloromethane (DCM), ethyl acetate and methanol were screened for their phytochemicals, total phenolics content, (TPC), total flavonoids content (TFC), total antioxidant content (TAC) and for their antifungal activity. Tannins, flavonoids, phenolic acids and alkaloids were mainly found in extracts, depending of the solvent used for extraction. TAC were evaluated using Ferric Reducing Antioxidant Power (FRAP) and DPPH radical scavenging assays. Results from FRAP assay showed that methanolic flower extracts had highest TAC (112.94 ± 2.4 μg TE/mg of extracts), followed by leaves (68.56 ± 7.53 μg TE/mg of extract), roots (45.17 ± 4.28 μg TE/mg of extracts) and stems (39.21 ± 2.34 μg TE/mg of extract). The highest TPC were found in methanolic flowers extracts (171.17 ± 1.42 GAE/mg of extract) whereas DCM and ethyl acetate roots extracts exhibited the best TFC with respectively 348.34 ± 12.48 and 323.86 ± 31.55 μg of QE/mg of extract. Only methanolic extracts of C. giganteus different parts were tested at 10 mg/mL on four local fungi. Results showed that methanolic roots extracts had an inhibitory effect of 16.16%, 19.15% and 10.79% respectively on the radial growth of Fusarium moniliforme, Phoma sorghina and Aspergillus flavius. Methanolic flowers extracts only inhibited Fusarium moniliforme radial growth at 19.4171% and Aspergillus flavius at 7.11%. None of plant parts extracts showed an inhibitory effect on Bypolaris orezae.
The large-scale magnetic field in the fourth Galactic quadrant

Aims. We have re-examined the published rotation measures (RMs) of extragalactic point sources and pulsars with |b| < 3 ◦ to study the magnetic field in the fourth Galactic quadrant. Methods. We reduced the influence of structure in electron density as much as possible by excluding objects for which Hα-data indicate large fluctuations in ne somewhere along the line of sight. We also excluded objects for which the RM may have been significantly “corrupted” by an intervening supernova remnant. We modeled RM(l), the longitude dependence of RMof the unaffected extragalactic sources and pulsars. Weassumed several geometries for thelarge-scalefield.All but one of those arebased on logarithmic spiral arms (with various pitch angles and widths), while one has circular symmetry. We also made different assumptions about the large-scale ne-distribution. Results. The data suggest the following generic behaviour of the large-scale field in the 4th Galactic quadrant. The field is most likely organized along logarithmic spiral arms and shows two significant reversals: from the Norma arm (CCW field) to the Norma-Crux interarm region (CW field), and from the Norma-Crux interarm region to the Crux arm (CCW field). The present data do not constrain the field in and beyond the Crux-Carina interarm region. Although the models give a good description of the global character of RM(l), individual RM-estimates deviate by typically 15 times their measurement errors. We argue that these large deviations are most likely due to the “small-scale” field that dominates on scales of up to several hundred pc. Conclusions. The picture that emerges is thus of a field that has significant structure on smaller scales, but for which the average values in arms and interarm regions are nevertheless well-defined. In addition, this smaller-amplitude large-scale field appears to reverse at each arm-interarm boundary that we can study with the present data. We briefly discuss the link between these results and theoretical predictions.
Palliative radiotherapy knowledge among community family physicians and nurses

Background. Primary care physicians and nurses care for patients with advanced cancer and need to be aware of the role for palliative radiotherapy (PR). Methods. We surveyed 250 family physicians, family medicine residents, and nurses attending oncology educational symposia to determine their knowledge of PR. Results. The survey response rate was 59%, and most respondents (77%) were involved with the care of cancer patients. Many (58%) thought that their knowledge of PR was insufficient for their needs. Although bone metastasis and spinal cord compression were frequently recognized indications for PR, only 50% of other assessed indications for PR were correctly identified. Almost all respondents stated that they wanted to learn more about PR. Conclusions. More education regarding PR is required for primary care physicians and nurses caring for cancer patients.
Molecular dynamics simulations of Ar + bombardment of Si with comparison to experiment

The authors present molecular dynamics (MD) simulations of energetic Ar+ ions (20–200eV) interacting with initially crystalline silicon, with quantitative comparison to experiment. Ar+ bombardment creates a damaged or amorphous region at the surface, which reaches a steady-state thickness that is a function of the impacting ion energy. Real-time spectroscopic ellipsometry data of the same phenomenon match the MD simulation well, as do analogous SRIM simulations. They define positional order parameters that detect a sharp interface between the amorphous and crystalline regions. They discuss the formation of this interesting feature in the simulation, and show that it provides insight into some assumptions made in the analysis of experimental data obtained by interface-sensitive surface spectroscopy techniques.
Avoiding order reduction when integrating linear initial boundary value problems with exponential splitting methods

It is well known the order reduction phenomenon which arises when exponential methods are used to integrate in time initial boundary value problems, so that the classical order of these methods is reduced. In particular, this subject has been recently studied for Lie-Trotter and Strang exponential splitting methods, and the order observed in practice has been exactly calculated. In this paper, a technique is suggested to avoid that order reduction. We deal directly with non-homogeneous time-dependent boundary conditions, without having to reduce the problem to homogeneous ones. We give a thorough error analysis of the full discretization and justify why the computational cost of the technique is negligible in comparison with the rest of the calculations of the method. Some numerical results for dimension splittings are shown which corroborate that much more accuracy is achieved. ∗Email: isaias@mac.uva. es †Corresponding author.

Biosensing using photonic crystal nanolasers

Photonic crystal nanolasers are fabricated and operated simply, and can be applied as disposable sensors for biomedical applications. They are sensitive to the change with environmental index and surface charge. Functionalizing the nanolaser surface with an antibody, the specific binding of target antigen is detected with a detection limit 2-4 orders lower than that achieved by current standard methods, enzyme-linked immuno-sorbent assay. Nanolasers also detect negatively-charged deoxyribonucleic acid from their emission intensity. This technique requires neither labels nor spectroscopy, which simplifies screening procedures. Its applicability for high-speed detection of endotoxin and for label-fee imaging of living cells are also demonstrated.
NU 273.pmd

This experiment was carried out at the at the poultry sector of the School of Veterinary Medicine and Animal Science – UNESP, Botucatu campus, and aimed at evaluating the effect of the inclusion of flavonoids along with mannan oligosaccharides (MOS) as compared to other additives on the performance, carcass and parts yields, and meat quality of broilers reared from 1 to 42 days of age. A total number of 1500 Cobb broilers were distributed according to a completely randomized experimental design into five treatments, with six replicates of 50 birds each. Treatments consisted of a control group, probiotic 1, probiotic 2, antibiotic, and flavonoids+MOS. For the period of 1 to 42 days of age, there were no differences among treatments as to daily weight gain, feed intake, mortality, and final body weight, but a significant difference was found for feed conversion ratio for the flavonoids+MOS treatment. Carcass and parts yields were not significantly influenced by the treatments. Tbars number, which indicates meat fat oxidation index, was significantly different in both refrigerated and frozen meat. The lowest oxidation index was obtained with the flavonoids+MOS treatments. Under the conditions of the present study, the supplementation of broiler diets with flavonoids+MOS was effective.
Brief report: Factors affecting outpatient follow-up compliance of emergency department patients

AbstractBACKGROUND: Emergency department (ED) patients often fail to follow-up with referrals to outpatient clinics and physicians. OBJECTIVE: To compare the effects of 2 ED discharge instructional methods on outpatient follow-up compliance and to evaluate sociodemographic characteristics as possible factors affecting outpatient follow-up compliance. DESIGN AND PARTICIPANTS: Randomized trial of ED patients. At discharge, the intervention group had their follow-up appointment made and the standard group was given our hospital’s referral service phone number to make their own follow-up appointment. MEASUREMENTS: Outpatient clinics were called 1 month after each subject’s ED discharge to ascertain if they followed-up. Poisson regression was used to examine the effects of sociodemographic factors on follow-up compliance. RESULTS: Of 287 eligible subjects, 250 (87%) agreed to participate. Follow-up rates were 59% for the intervention group and 37% for the standard group (P<.001). Having a primary care physicians appeared to increase ED patients’ outpatient follow-up compliance and having Medicaid insurance appeared to decrease outpatient follow-up compliance, but neither of these findings was statistically significant. CONCLUSIONS: In our ED, patients who have their outpatient follow-up appointment made at discharge have a significantly greater probability of follow-up compliance compared with patients given standard discharge instructions. Most sociodemographic characteristics do not affect out ED patients’ follow-up compliance.
