Recycle, Bury, or Burn Wood Waste Biomass?: LCA Answer Depends on Carbon Accounting, Emissions Controls, Displaced Fuels, and Impact Costs

This study extends existing life cycle assessment (LCA) literature by assessing seven environmental burdens and an overall monetized environmental score for eight recycle, bury, or burn options to manage clean wood wastes generated at construction and demolition activity sites. The study assesses direct environmental impacts along with substitution effects from displacing fossil fuels and managed forest wood sourcing activities. Follow‐on effects on forest carbon stocks, land use, and fuel markets are not assessed. Sensitivity analysis addresses landfill carbon storage and biodegradation rates, atmospheric emissions controls, displaced fuel types, and two alternative carbon accounting methods commonly used for waste management LCAs. Base‐case carbon accounting considers emissions and uptakes of all biogenic and fossil carbon compounds, including biogenic carbon dioxide. Base‐case results show that recycling options (recycling into reconstituted wood products or into wood pulp for papermaking) rank better than all burning or burying options for overall monetized score as well as for climate impacts, except that wood substitution for coal in industrial boilers is slightly better than recycling for the climate. Wood substitution for natural gas boiler fuel has the highest environmental impacts. Sensitivity analysis shows the overall monetized score rankings for recycling options to be robust except for the carbon accounting method, for which all options are highly sensitive. Under one of the alternative methods, wood substitution for coal boiler fuel and landfill options with high methane capture efficiency are the best for the overall score; recycling options are next to the worst. Under the other accounting alternative, wood substitution for coal and waste‐to‐energy are the best, followed by recycling options.
All Three Domains of the Hepatitis C Virus Nonstructural NS5A Protein Contribute to RNA Binding

ABSTRACT The hepatitis C virus (HCV) nonstructural protein NS5A is critical for viral genome replication and is thought to interact directly with both the RNA-dependent RNA polymerase, NS5B, and viral RNA. NS5A consists of three domains which have, as yet, undefined roles in viral replication and assembly. In order to define the regions that mediate the interaction with RNA, specifically the HCV 3′ untranslated region (UTR) positive-strand RNA, constructs of different domain combinations were cloned, bacterially expressed, and purified to homogeneity. Each of these purified proteins was probed for its ability to interact with the 3′ UTR RNA using filter binding and gel electrophoretic mobility shift assays, revealing differences in their RNA binding efficiencies and affinities. A specific interaction between domains I and II of NS5A and the 3′ UTR RNA was identified, suggesting that these are the RNA binding domains of NS5A. Domain III showed low in vitro RNA binding capacity. Filter binding and competition analyses identified differences between NS5A and NS5B in their specificities for defined regions of the 3′ UTR. The preference of NS5A, in contrast to NS5B, for the polypyrimidine tract highlights an aspect of 3′ UTR RNA recognition by NS5A which may play a role in the control or enhancement of HCV genome replication.
Effects of water immersion on sympathoadrenal and dopa-dopamine systems in humans.

Water immersion to the neck increases central blood volume and evokes a marked diuresis and natriuresis. The present study examined simultaneously effects of water immersion on activities of three endogenous systems thought to participate in sodium homeostasis: the sympathetic nervous system, the atrial natriuretic peptide system, and the renal dopa-dopamine system. Hourly urine collections and antecubital venous blood samples were obtained from 10 normal subjects before, during, and after sitting in a water-immersion tank for 3 h; four control subjects were studied while seated without immersion. Urine volume was increased by more than threefold after 1 h of immersion (from 1.2 +/- 0.2 ml/min at baseline to 5.9 +/- 0.7 ml/min, P less than 0.001) and peaked during the second hour. Urinary sodium excretion increased by more than twofold (from 103 +/- 17 mu eq/min at baseline to 196 +/- 36 mu eq/min at 1 h, P less than 0.001) and peaked during the third hour. Plasma levels and urinary excretion of norepinephrine (NE) and epinephrine were suppressed consistently during immersion (P less than 0.05). There was a marked, prompt, and sustained increase in plasma levels of immunoreactive atrial natriuretic factor (irANF) from 6.9 +/- 1.9 pg/ml baseline to 17.3 +/- 4.3 pg/ml at 1 h (P less than 0.001). Urinary excretion of dopa, dopamine, and 3,4-dihydroxyphenylglycol, a neuronal metabolite of NE, changed in a triphasic pattern, with decreased excretion during the first hour of immersion (P less than 0.01), small but consistent increases during the next 2 h, and decreased excretion, to below baseline, during recovery (P less than 0.01 for dopa and dopamine).

The impact of health plan delivery system organization on clinical quality and patient satisfaction.

OBJECTIVES The purpose of this study was to examine the extent to which measures of health plan clinical performance and measures of patient perceptions of care are associated with health plan organizational characteristics, including the percentage of care provided based on a group or staff model delivery system, for-profit (tax) status, and affiliation with a national managed care firm. DATA SOURCES Data describing health plans on region, age of health plan, for-profit status, affiliation with a national managed care firm, percentage of Medicare business, total enrollment, ratio of primary care physicians to specialists, HMO penetration, and form of health care delivery system (e.g., IPA, network, mixed, staff, group) were obtained from InterStudy. Clinical performance measures for women's health screening rates, child and adolescent immunization rates, heart disease screening rates, diabetes screening rates, and smoking cessation were developed from HEDIS data. Measures of patient perceptions of care are obtained from CAHPS survey data submitted as Healthplan Employer Data and Information Set, Consumer Assessment of Health Plans 2.0 H. STUDY DESIGN Multivariate regression cross-sectional analysis of 272 health plans was used to evaluate the relationship of health plan characteristics with measures of clinical performance and patient perceptions of care. PRINCIPAL FINDINGS The form of delivery system, measured by percent of care delivered by staff and group model systems, is significantly related (p < or = .05) with four of the five clinical performance indices but none of the three satisfaction performance indices. Other variables significantly associated with performance were being geographically located in the Northeast, having nonprofit status, and for patient satisfaction, not being part of a larger insurance company. CONCLUSIONS These comparative results provide evidence suggesting that the type of delivery system used by health plans is related to many clinical performance measures but is not related to patient perceptions of care. These findings underscore the importance of the form of the delivery system and the need for further inquiry that examines the relationship between organizational form and performance.
First Heart Sound Detection for Phonocardiogram Segmentation

This paper presents an algorithm for accurate and improved detection of the first heart sound S1 for heart sound cardiac cycle segmentation under noisy environments. The proposed algorithm integrates an S1/S2 selection step and an S1 identification step. An adaptive sub-level tracking algorithm based on wavelet transform is proposed to separate the S1 and S2 from other components such as murmurs and noises. This is followed by a detection procedure based on Shannon energy to reject the overlapping interference so that the peaks of S1 and S2 can be detected. Criteria of time interval, energy and phonocardiogram (PCG) collecting position are used to identify S1 with respect to the beginning of each cardiac cycle. Experimental results show that the proposed algorithm leads to an efficient segmentation of PCG cycle. Due to its simplicity and fast implementation, the method can be deployed clinically for further analysis and eventual use
Immunopathogenesis of Pulmonary Granulomas in the Guinea Pig after Infection with Mycobacterium tuberculosis

ABSTRACT Pulmonary tuberculosis in guinea pigs is similar to the disease in humans and is accordingly widely used as a model to test tuberculosis vaccines. The primary site of expression of acquired immunity and the hallmark of tuberculosis is the granuloma. Granuloma morphology is well described, but there is limited information regarding T-cell subset influx. We monitored the course of pulmonary tuberculosis in guinea pigs and observed four distinct immunohistopathological stages. In all stages there were similar numbers and arrangement of CD4 and CD8 T cells. There were only small numbers of apoptotic lymphocytes, scattered around and within the necrotic core, and acid-fast bacilli were visible both within macrophages and free within airway debris. A key finding of the study was the observation that the development of the necrotic core was an early event and almost certainly preceded the emergence of the acquired immune response. This in turn suggests that innate mechanisms are the basis of the early lesions and that subsequent acquired responses are unable to moderate them. This hypothesis differs from the current dogma that excessive activity of T cells mediates delayed-type hypersensitivity and that cellular cytolysis is the root cause of the necrosis.
Improved control on the complementary half controlled three phase PWM boost rectifier

In order to improve the performance of complementary half controlled three phase PWM boost rectifier, an improved control scheme including the current coordinate control and grid voltage oriented control is proposed. The current coordinate control is applied to obtain sinusoidal grid-side input currents and steady DC bus voltages. Grid voltage oriented control is applied to eliminate the impact of grid voltage distortion on grid-side input currents and implement independent control of active and reactive power. The simulation model using the Matlab/simulink was built to validate the availability of the proposed control scheme. The simulation results demonstrate that the low THD of the input current and the steady DC voltage can be obtained even if the grid voltage is distorted with the unbalanced and harmonic component.
Membrane tubulin

Tubulin has been identified as a membrane component of nerve synaptosomes and myelin, plasma membranes of platelets, thyroid, and tissue culture cells, brain and liver coated vesicles, mitochondria, and in cilia but not flagella of certain molluscs. Membrane tubulin can differ from cytoplasmic forms in isoelectric point, non‐polar amino acid substitutions, lack of carboxy‐terminal tyrosine, carbohydrate content, and selective ability to reassociate with lipids. This tubulin may function as an attachment site for binding vesicles or plasma membranes to cytoplasmic microtubules, as a source of precursor tubulin at the growing tips of axonemes, or as a component of signal transduction in sensory cilia.
Identification of a human immunodeficiency virus type 1 that stably uses tRNALys1,2 rather than tRNALys,3 for initiation of reverse transcription.

HIV-1 virions contain approximately equal amounts of tRNALys,3 and tRNALys1,2, yet tRNALys,3 has been found to be exclusively used for initiation of reverse transcription. Since previous studies have shown that even if the primer binding site (PBS) was mutated to be complementary to tRNALys1,2, the virus did not stably use tRNALys1,2 to initiate reverse transcription, the virus must have evolved a mechanism for the exclusive use of tRNALys,3 to initiate reverse transcription. To investigate how HIV-1 discriminates tRNALys1,2 from tRNALys,3 for initiation of reverse transcription, two proviral genomes that contain nucleotide changes in U5 and a PBS to be complementary to regions of tRNALys1,2 were constructed. One genome contains 5 [HXB2(L12-AC)] nucleotides while another contains 15 [HXB2(L12-ACgg)] nucleotides in U5 complementary to the anticodon region of tRNALys1,2. Viruses derived from the transfection of the proviral genomes were infectious in SupT1 cells. Analysis of the endogenous reverse transcription reactions from viruses derived from HXB2 (L12-AC) and HXB2 (L12-ACgg) obtained from transfection revealed that both exclusively used tRNALys1,2 to initiate reverse transcription. Following extensive in vitro culture, though, sequence analysis of proviral genomes revealed that while the virus derived from HXB2(L12-AC) stably maintained a PBS complementary to tRNALys1,2, the virus derived from HXB2 (L12-ACgg) had reverted back to contain a PBS complementary to tRNALys,3. RNA modeling of the U5-PBS of the genome from HXB2(L12-AC) supports the conclusion that the fine specificity for discrimination between tRNALys,3 and tRNALys1,2 for use as a primer for HIV-1 reverse transcription resides in the structure of the U5-PBS region of the viral genome.
Weekly Intravenous and Intraperitoneal Paclitaxel Combined with S-1 for Malignant Ascites due to Advanced Gastric Cancer

Malignant ascites caused by gastric cancer are chemotherapy resistant and carry a poor prognosis. The efficacy of a regimen including intraperitoneal paclitaxel (PTX) was evaluated in 33 gastric cancer patients with ascetic fluid in the peritoneal cavity diagnosed with computed tomography (CT) scanning. Synchronous administration of intravenous (50 mg/m2) and intraperitoneal (20 mg/m2) PTX was performed via a subcutaneously placed intraperitoneal catheter on days 1 and 8, and S-1 was administered twice daily at 80 mg/m2/day for 14 consecutive days from day 1 to day 14, followed by 7 days of rest. The ascitic fluid volume was calculated with NIH Image J software using continuous CT images. After 2–4 treatment cycles, 23 (70%) patients showed reductions in their ascitic volumes of >50%. Ascites disappeared completely in 8 patients and were markedly reduced (to <3% of the original volume) in 4 of the 9 patients (44%) who initially had massive (>2,500 ml) ascites. Median overall survival was significantly better in patients with ascitic reduction. Weekly intravenous and intraperitoneal PTX combined with S-1 was highly effective in gastric cancer with malignant ascites. The change in ascitic fluid volumes determined by CT image measurements is a useful predictor of outcome in these patients.
The Role of Performance Reporting System Characteristics for the Coordination of High-Cost Areas in Hospitals

Abstract This paper explores the role of a performance reporting regime’s characteristics for two non-financial performance measures that are commonly used in the management of operating theaters (OTs) in German hospitals. The performance measures are the on-time first case of the day starts and the percentage of deviations from the short-term OT plan. The characteristics studied are reporting detail, reporting method and reporting frequency. We find that the degree of detail that the reporting system provides on the causes of negative performance exerts a significant positive effect on both performance measures. The reporting method and frequency do not affect performance. We also study the effect of existing processual, organizational and governance-related problems on performance. We find that these problems exert a significant negative effect on performance but that performance can be improved by detailed reporting.
Evidence that helping at the nest does not result in territory inheritance in the Seychelles warbler

In an environment that has a shortage of territories, helping to rear younger siblings (‘alloparenting’) is proposed to facilitate territory acquisition in two ways: (i) through group augmentation that leads to an increase of the territory with subsequent partial inheritance (budding); and (ii) through site dominance that leads to greater success when competing for the natal or a nearby territory after the death of the territory owner (complete territory inheritance). Most young Seychelles warbler (Acrocephalus sechellensis) males either show alloparenting or budding behaviour. Future budders had significantly more aggressive interactions with neighbours and assisted their parents more with territory defence than similarly aged future alloparents or non–helpers. This led to an increase of the natal territory of future budders before actual budding took place, whereas the natal territories of future alloparents remained constant in size. Alloparents never became budders and vice versa, refuting partial inheritance as an advantage of alloparenting. Natural male breeding vacancies were never inherited by alloparents born on vacant or other territories, but were inherited by budders born on the vacant territory or, if these were absent, predominantly by budders from neighbouring territories. We offer explicit experimental evidence against the ‘helping at the nest to inherit’ hypothesis. Experimentally created male breeding vacancies, with both a male alloparent and a similarly aged sibling budder present simultaneously in the vacant territory, were filled by budders only. Site dominance over territory inheritance is linked to budding and not to alloparenting.
Pathophysiology of Age-Related Cerebral White Matter Changes

The pathogenesis of age-related cerebral white matter changes (WMC) is still a matter of investigation. Alterations of deep small vessels, such as arteriolosclerosis, are considered to play a central role in the development of WMC. Stenosis or occlusion of small vessels may cause sudden or more chronic ischemia resulting in small areas of necrosis (lacunar infarction) or diffuse alterations consistent with the definition of white matter incomplete infarct. Moreover, the arteriolosclerotic changes may cause loss of autoregulation in the deep white matter and consequent cerebral blood flow fluctuations in response to changes of systemic blood pressure. Both these types of mechanisms may be particularly harmful because the blood supply of the white matter is of the terminal type with scarce anastomoses. Other pathophysiological hypotheses on the origin of WMC have been raised, and they can probably be considered as complementary to the ischemic one. The small vessel alterations could lead to damage of the blood-brain barrier and chronic leakage of fluid and macromolecules in the white matter. The increased interstitial fluid concentration in abnormal white matter may be also a consequence of arterial hypertensive bouts. Genetically determined factors could play an important role in the development of WMC, and at least one disease (cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy – CADASIL) characterized by severe leukoencephalopathy exists with a determined genetic origin. It is possible that other genetic factors contribute, by interaction with conventional risk factors, to the development of white matter injury in nonfamilial cases.
A Comparison of Omaha Worksite Health Promotion Activities to the 1992 National Survey with a Special Perspective on Program Intervention

Purpose. The purpose of this study was to compare the results from a survey of Omaha worksite health promotion activities with the results of a 1992 national survey. Comparisons were made on: (1) the kinds of health promotion activities offered, (2) progress toward the Healthy People 2000 worksite objectives, (3) types of program intervention offered, and (4) administrative factors. Design. A one-time, written, mail-out/mail-back survey design was used. Setting. The study took place in Omaha, Nebraska. Subjects. All area public and private worksites with 250 or more employees were sent surveys. Individuals who were preselected and identified as the best qualified within the company completed the survey instrument. Of the 176 worksites surveyed, 86 completed the survey (49%). Measures. Descriptive statistics (percentages) were used to compare the two surveys on kinds of programs offered, progress toward Healthy People 2000 related to worksite health promotion, the types of program intervention offered, and administrative factors. Results. Generally, a greater percentage of respondent worksites from the national survey are offering more health promotion activities and have made more progress toward the Healthy People 2000 worksite objectives than the Omaha worksites. Results from both surveys showed that low levels of intervention are more prevalent than high levels of intervention, and that health promotion activities in most worksites are coordinated by human resources departments and not by someone professionally prepared in health education. Conclusions. Traditionally, major goals of worksite health promotion programs have focused on important organizational outcomes such as improved productivity/morale, reduction in absenteeism, and health care cost-containment. It is important to recognize, however, that low levels of intervention have less impact than more intensive programs on these desired outcomes. Future goals for local and national worksite health promotion programs may need to encourage implementation of more intensive intervention programs.
The role of positron emission tomography in the management of bone metastases

Positron emission tomography (PET) is a nuclear medicine technique that only recently has been widely used in clinical oncology. PET, as a metabolic imaging technique, demonstrates advantages over and complements structural imaging methods and also demonstrates differences from conventional nuclear medicine, all of which has led to its enormous growth in clinical applications in recent years.
An internet based interactive telemedicine system for remote healthcare

To enable remote monitoring and diagnosis of patients located far from medical facilities, a prototype Internet based telemedicine system is developed. The developed telemedicine system establishes an audio-visual connection as well as a data path from the patient's home to the medical personnel's office through a web browser interface. A remote controlled wireless camera installed on the patient side can be tilted, zoomed, and panned by the doctor, at the medical facility, to examine different parts of the patient's body through the web interface. Unlike many of the existing systems, the established data path enables additional diagnosis functions such as electrocardiogram, blood pressure, respiration, temperature, and stethoscope. Results from laboratory and field testing of the developed system are presented and avenues for broader implementation in integrated facilities using low cost wireless networks will be discussed.
How have global financial institutions responded to the challenges of the post-crisis era?

ABSTRACT The study examines the largely unexplored effect of changes in the competitive landscape for large, global financial institutions on their ability to take risks, as well as deploy capital and labour in an efficient manner based on a novel measure of inefficiency. The analysis shows during 2001–2013 that inefficiency peaked during the 2008 crisis period and has fallen back to levels close to pre-crisis periods. The model also performs well in out-of-sample forecasts of the financial firms’ future market values. These results suggest that large financial firms have been adjusting to the ‘new normal’ of the post-crisis period and thus are able to use capital and labour more efficiently within the constraints of current market conditions. In addition, a non-linear pattern between inefficiency and a firm’s asset size suggests that there might be an optimal scale for such firms in the $450–650 billion range.
