Anaerobic Biotransformation of High Concentrations of Chloroform by an Enrichment Culture and Two Bacterial Isolates

ABSTRACT A fermentative enrichment culture (designated DHM-1) was developed that is capable of cometabolically biotransforming high concentrations of chloroform (CF) to nontoxic end products. Two Pantoea spp. were isolated from DHM-1 that also possess this dechlorination capability. Following acclimation to increasing levels of CF, corn syrup-grown DHM-1 was able to transform over 500 mg/liter CF in the presence of vitamin B12 (approximately 3% of CF on a molar basis) at a rate as high as 22 mg/liter/day in a mineral salts medium. CO, CO2, and organic acids were the predominant biodegradation products, suggesting that hydrolytic reactions predominate during CF transformation. DHM-1 was capable of growing on corn syrup in the presence of high concentrations of CF (as may be present near contaminant source zones in groundwater), which makes it a promising culture for bioaugmentation. Strains DHM-1B and DHM-1T transform CF at rates similar to that of the DHM-1 enrichment culture. The ability of these strains to grow in the presence of high concentrations of CF appears to be related to alteration of membrane fluidity or homeoviscous and homeophasic adaptation.
Crowdfunding's potential for the developing world

Crowdfunding is an Internet-enabled way for businesses or other organizations to raise money in the form of either donations or investments from multiple individuals. This new form of capital formation emerged in the wake of the 2008 financial crisis largely because of the difficulties faced by artisans, entrepreneurs and early-stage enterprises in raising funds. Crowdfunding takes advantage of crowd-based decision-making and innovation, and applies it to the funding of projects or businesses. Using social networks, social profiles, and web-based communication, individuals and companies have raised billions of dollars in debt, equity, and donations for projects. Building a crowdfunding ecosystem depends on key enablers to build trust. This document explores specific strategies to drive crowdfunding, the risks in crowdfunding and how to mitigate them, and the potential use of crowdfunding in the developing world.
Functional imaging of brain regions sensitive to communication sounds in primates

There is considerable brain imaging evidence on the neural substrates of speech in humans, but only recently has data for comparison become available on the brain regions that process communication signals in other primates. To obtain insights into the relationship between the substrates for communication in primates, we compared the results from several neuroimaging studies in humans with those that have recently been obtained from macaque monkeys and chimpanzees. We note a striking general correspondence between the primates on the pattern of brain regions that process species-specific vocalizations and the acoustics related to voice identity.
Technology Acceptance, Acceptabilty and Appropriation in Professionnal Bureaucracies : The Case of RFID for Improving Mobile Assets Management in Hospitals

Hospitals, even small ones, handle on a daily basis several thousands of mobile and fixed assets. Mobile assets are very diverse, ranging from infusion pumps, surgical equipment, electrocardiograms, portable x-ray machines, defibrillators to wheelchairs and rotate constantly between different medical wards. Since virtually every patient depends on one or more mobile assets during his or her hospital stay, they are also indispensable in healthcare delivery. Clinical staff spends a significant share of their working time searching for these essential, but commonly misplaced assets. Locating mobile assets is not only a time consuming activity, but the inability to find them when needed is remarkably costly, and possibly life threatening. RFID (Radio Frequency Identification) holds the potential to uniquely and seamlessly track and trace mobile assets and, thus, to improve mobile asset management in hospitals. Compared to other sectors, healthcare organizations adopt RFID at a much slower pace and only a limited number of empirical studies address RFID adoption and implementation in the context of healthcare. This thesis intends to contribute the research arena by analysing a real-life RFID implementation in order improve the management activities of one type of mobile assets, namely infusion pumps in hospital settings. The research focuses on a real-life RFID implementation in one European hospital. Empirical data was collected for a 25 month period from the pre-feasibility stage to post-implementation stage from eight organizations (including the hospital as the main observation site) and from thirty-five participants. Research results can be summarized as follows. To the question why RFID is implemented? The most straightforward answer is to reduce the existing inefficiencies related to mobile assets management. Technological preparedness and readiness drive RFID implementation: This includes familiarity with IT innovations within the hospital, compatibility with existing IT infrastructure (the hospital is almost 100% Wi-Fi enabled), and experience of technological partners with RFID implementation in various sectors. How RFID implementation is carried out? The answer seems to be through a highly iterative five stage process where participants revisited and modified previously agreed steps. The continuous improvement of care services was without a doubt the superseding concern expressed
The Perception of Punctuality in the Management of Time

This article examines the perception of Zimbabweans on time management, particularly on punctuality. It is observed that the perception of time management may be heavily dependent on the culture of a nation and the ethnicity of its citizens. A survey was carried out with 61 randomly selected participants completing a questionnaire. The results did indicate a gross neglect of time as evidenced by the percentage of people that are generally late for various gatherings such as meetings, lectures, conferences, church services and weddings. In some cases, the failure to meet specified times was as a result of nationally controlled factors such as road blocks intended to protect the safety of the passengers who use public service vehicles. Besides being delayed unnecessarily the results generally indicate that in Zimbabwe the range of time in which a person can be said to be late is too wide and has possible effects on the economic development of the nation. Key Words: Punctuality, Time, Time Management, Meetings, Time Day
Spin-wave excitation spectra and spectral weights in square lattice antiferromagnets.

Using a recently developed method for calculating series expansions of the excitation spectra of quantum lattice models, we obtain the spin-wave spectra for square lattice, S=1/2 Heisenberg-Ising antiferromagnets. The calculated spin-wave spectrum for the Heisenberg model is close to but noticeably different from a uniformly renormalized classical (large-S) spectrum with the renormalization for the spin-wave velocity of approximately 1.18. The relative weights of the single-magnon and multiple-magnon contributions to neutron-scattering spectra are obtained for wave vectors throughout the Brillouin zone.
Regulation of Motor Representation by Phase–Amplitude Coupling in the Sensorimotor Cortex

High-γ amplitude (80–150 Hz) represents motor information, such as movement types, on the sensorimotor cortex. In several cortical areas, high-γ amplitudes are coupled with low-frequency phases, e.g., α and θ (phase–amplitude coupling, PAC). However, such coupling has not been studied in the sensorimotor cortex; thus, its potential functional role has yet to be explored. We investigated PAC of high-γ amplitude in the sensorimotor cortex during waiting for and the execution of movements using electrocorticographic (ECoG) recordings in humans. ECoG signals were recorded from the sensorimotor cortices of 4 epilepsy patients while they performed three different hand movements. A subset of electrodes showed high-γ activity selective to movement type around the timing of motor execution, while the same electrodes showed nonselective high-γ activity during the waiting period (>2 s before execution). Cross frequency coupling analysis revealed that the high-γ amplitude during waiting was strongly coupled with the α phase (10–14 Hz) at the electrodes with movement-selective high-γ amplitudes during execution. This coupling constituted the high-γ amplitude peaking around the trough of the α oscillation, and its strength and phase were not predictive of movement type. As the coupling attenuated toward the timing of motor execution, the high-γ amplitude appeared to be released from the α phase to build a motor representation with phase-independent activity. Our results suggest that PAC modulates motor representation in the sensorimotor cortex by holding and releasing high-γ activity in movement-selective cortical regions.
On the Cohomology Comparison Theorem

A relative derived category for the category of modules over a presheaf of algebras is constructed to identify the relative Yoneda and Hochschild cohomologies with its homomorphism groups. The properties of a functor between this category and the relative derived category of modules over the algebra associated to the presheaf are studied. We obtain a generalization of the $Special$ $ Cohomology$ $Comparison$ $Theorem$ of M. Gerstenhaber and S. D. Schack.
An investigation of auditors' perceptions of potential factors influencing auditor independence: a case based on selected Indonesian auditors

Most (if not all) studies on the perceptions of auditor independence were conducted using a quantitative approach. Sending questionnaires to collect data and testing hypothesis by the use of statistics have been very c o m m o n . T h e lack of literature on auditor independence using a qualitative approach has inspired this present study, since the advantages of the qualitative approach cannot be reached by the quantitative. This is a perceptual study of auditor independence using an ethnographic, qualitative approach. Twenty-nine Indonesian auditors have been interviewed, in order to investigate their perceptions of factors that could affect auditor independence. T w o theoretical models of independence, auditors-firms conflict of interest of G o l d m a n and Barlev (1974) and Flint's (1988) material circumstances to independence, are used to explore the issues that were investigated. These issues are not "truths" to be proven, but used rather as interview guidelines. T h e interview data are summarised and pattern coded as proposed by Miles and H u b e r m a n (1984) and then analysed through description, analysis and interpretation suggested b y Wolcott (1994). T h e use of pattern coding allows the researcher to classify answers and compare responses. T h e analysis introduced b y Wolcott allows the researcher not only to analyse what auditors say but also to interpret beyond what they say. This study found that auditor independence would potentially depend on external and internal factors or circumstances. T h e external factors or circumstances are audit firms' characteristics, clients' characteristics, the nature of auditors and clients relationship and sanctions enforced. Audit firms' characteristics included the size of the audit firm and non-audit services rendered to audit clients. T h e clients' backgrounds, existence of a corporate audit committee and clients' contribution to audit fees are regarded as clients' circumstances that could influence auditor independence. Competition a m o n g auditors, clients' directors' roles and the length of audit engagement are consequences of their relationship that could affect auditor independence. Sanctions enforced by the professional b o d y could also influence auditor independence. O n the other hand, internal factors influencing auditor independence c o m e s from auditors themselves. T h e state of professional ethics of auditors as a consequence of professionalism and the auditors' religious values affect auditor independence.
Relationship of Body Core Temperature and Warm-up to Knee Range of Motion.

This study examined the effects of submaximal, treadmill exercise-induced body core temperature (BCT) increase on selected knee range of motion (ROM). Twenty males, 18-35 years old, were tested (randomized crossover) for ROM, BCT, and heart rate (HR), followed by either Treatment I (20 minutes of rest) or Treatment II (20 minutes of submaximal running). The two treatments were subsequently followed by a two-minute passive stretch. Range of motion was assessed before and after passive stretch treatment intervention. Treatment means differed for BCT and HR (p < 0.001) but not for ROM after exercise intervention. It was concluded that 20 minutes of exercise increased BCT (>1 degrees C) but had no effect on knee ROM. J Orthop Sports Phys Ther 1991;13(3):126-131.
THE EXPERIENCE AND DEVELOPMENT OF RESPONSIBLE AND ECO-FRIENDLY AQUACULTURE PRODUCTION PRACTICES FOR FOOD SAFETY AND TRACEABILITY IN TAIWAN

Awareness of environmental conservation, food safety, and responsible aquaculture production has been the key factors to changes in the development of the world aquaculture and seafood communities. Aquaculture plays an important role in supplying fish for the increasing population and has become one of the main sources of animal proteins. The catches from the sea were not able to increase due to the reduced quotas across open seas, limited fishing periods and areas, and increased license fees. To meet this trend, the aquaculture industry has to prepare to enter an era of restructuring and increasing concern for sustainability. Recent developments in responsible and eco-friendly aquaculture production practices to enhance aquaculture food safety and traceability in Taiwan are described in this paper.

Prognostic Factors in Early-Stage Leiomyosarcoma of the Uterus

Uterine leiomyosarcomas (LMSs) are rare cancers representing less than 1% of all uterine malignancies. Clinical International Federation of Gynecology and Obstetrics (FIGO) stage is the most important prognostic factor. Other significant prognostic factors, especially for early stages, are difficult to establish because most of the published studies have included localized and extra-pelvian sarcomas. The aim of our study was to search for significant prognostic factors in clinical stage I and II uterine LMS. The pathologic features of 108 uterine LMS including 72 stage I and II lesions were reviewed using standardized criteria. The prognostic significance of different pathologic features was assessed. The median follow-up in the whole group was 64 months (range, 6-223 months). The 5-year overall survival (OS) and metastasis-free interval and local relapse-free interval rates in the whole group and early-stage group (FIGO stages I and II) were 40% and 57%, 42% and 50%, 56% and 62%, respectively. Clinical FIGO stage was the most important prognostic factor for OS in the whole group (P = 4 × 10−15). In the stage I and II group, macroscopic circumscription was the most significant factor predicting OS (P = 0.001). In the same group, mitotic score and vascular invasion were associated with metastasis-free interval (P = 0.03 and P = 0.04, respectively). Uterine LMSs diagnosed using standardized criteria have a poor prognosis, and clinical FIGO stage is an ominous prognostic factor. In early-stage LMS, pathologic features such as mitotic score, vascular invasion, and tumor circumscription significantly impact patient outcome.
When resources get sparse: A longitudinal, qualitative study of emotions, coping and resource-creation when parenting a young child with severe disabilities

Parents who realize that their newborn child is severely disabled often experience severe physical and emotional stress. Parental well-being is essential for the care-taking of the child. It is yet not known why some cope well and others do not. The aim of this study was to explore how parents coped with parenting a disabled child and how they maintained their energy and personal resources. We explored parents’ experiences, coping and resources over a two-year period after their child was diagnosed with a severely disabling condition using a qualitative, longitudinal approach. Findings were interpreted in a theoretical framework of Lazarus and Folkman’s studies on coping and Fredrickson’s broaden-and-build theory of positive emotions, as well as theories of positive illusions and benefit finding during severe adversity. We found that parents continually created and sustained their personal resources through positive cognitive reappraisals of their circumstances, the consequences of those circumstances and their coping possibilities. Nine main coping strategies were identified constituting transformative pathways in resource-creation. A theory of resource-creation is proposed as an addition to the current understanding of coping and the role of positive emotions. Coping and resources were found to be closely interrelated and portals of intervention are discussed.
Light and Plastid Signals Regulate Different Sets of Genes in the Albino Mutant Pap7-11[OPEN]

The albino pap7-1 mutant of Arabidopsis reveals the relative impact of light and plastid developmental stage on the expression of nuclear genes involved in metabolism and photosynthesis. Plants possessing dysfunctional plastids due to defects in pigment biosynthesis or translation are known to repress photosynthesis-associated nuclear genes via retrograde signals from the disturbed organelles toward the nucleus. These signals are thought to be essential for proper biogenesis and function of the plastid. Mutants lacking plastid-encoded RNA polymerase-associated proteins (PAPs) display a genetic arrest in eoplast-chloroplast transition leading to an albino phenotype in the light. Retrograde signaling in these mutants, therefore, could be expected to be similar as under conditions inducing plastid dysfunction. To answer this question, we performed plastome- and genomewide array analyses in the pap7-1 mutant of Arabidopsis (Arabidopsis thaliana). In parallel, we determined the potential overlap with light-regulated expression networks. To this end, we performed a comparative expression profiling approach using light- and dark-grown wild-type plants as relative control for the expression profiles obtained from light-grown pap7-1 mutants. Our data indicate a specific impact of retrograde signals on metabolism-related genes in pap7-1 mutants reflecting the starvation situation of the albino seedlings. In contrast, light regulation of PhANGs and other nuclear gene groups appears to be fully functional in this mutant, indicating that a block in chloroplast biogenesis per se does not repress expression of them as suggested by earlier studies. Only genes for light harvesting complex proteins displayed a significant repression indicating an exclusive retrograde impact on this gene family. Our results indicate that chloroplasts and arrested plastids each emit specific signals that control different target gene modules both in positive and negative manner.

Urinary tract infections and lupus erythematosus

Background: Infections are one of the main causes of morbidity and mortality in patients with systemic lupus erythematosus. Objective: To analyse urinary tract infection (UTI) risk factors in lupus patients; the influence of these factors on disease activity, organ damage, and disease development; the type and prevalence of UTI; and the micro-organisms involved. Method: 86 control subjects and 81 lupus patients were studied prospectively over a 12 month period and examined on five occasions. Epidemiological data and information on urinary symptoms, disease activity (SLEDAI), and organ damage (SLICC/ACR) data were collected. Autoantibodies, complement levels, urine culture, and antibiogram were determined; urological studies were also carried out. SPPS 10.0 and STATA 6.0. were used for statistical analysis. Results: The prevalence of UTI in lupus patients was 36%. Lupus influences the onset of UTI (p = 0.001), regardless of other variables. UTI risk factors in lupus patients were age (p = 0.002), previous cases of UTI (p = 0.0001), antinuclear antibodies (ANA) >1/80 IU/ml (p = 0.022), thrombocytopenia (p = 0.02), and admission to hospital due to UTI (p = 0.002). Leucopenia (p = 0.09) and the weekly administration of methotrexate (p = 0.06) had a bearing on the onset of UTI; disease development (p = 0.99), lupus activity (p = 0.32), and organ damage (p = 0.36) do not. The uropathogen most frequently isolated was E coli (60%). Conclusions: Lupus patients are likely to have UTI, usually manifesting in the lower tract. They are community acquired, basically caused by E coli, and favoured by age, previous UTI, admissions to hospital due to UTI, thrombopenia, ANA, leucopenia, and methotrexate treatments.
