Partial discharge measurements: becoming a fundamental tool for quality control and risk assessment of electrical systems?

This paper will introduce innovative technologies for partial discharge (PD) measurements, trying to answer to the common question that is associated with PD detection, that is, its effectiveness regarding fundamental items for asset management as risk assessment and maintenance planning. To this aim, the application of PD diagnosis to various electrical apparatus, specifically cables, generators and transformers, is discussed, emphasizing important features for PD detection and diagnosis such as noise cancellation, PD phenomena separation and identification, and PD source location
Cognitive Diversity and Team Performance: A Review

During past there is an extensive research on the concept of cognitive diversity and the team performance. However, the relationship direction of the team cognitive diversity and performance is not yet fully answered. There are mixed arguments for the positive and the negative relationships. This paper is the comprehensive study of the relationship of cognitive diversity and the team performance. It clarifies our thinking related to the different positive and negative interpretations by the academicians and practitioners for the relationship. From the past literature major support is given to the positive consequences of the cognitive diversity on team performance but still the negative consequences cannot be ignored. The major implications of the study for the future research are also discussed.
Corporate Governance and Risk Management at Unprotected Banks: National Banks in the 1890s

We examine bank governance and risk choices from the 1890s, a period without distortions from deposit insurance or other government assistance to banks. We link differences in managerial ownership to different corporate governance policies, risk, and methods of risk management. Formal corporate governance and high manager ownership are negatively correlated. Managerial salaries and self-lending are greater when managerial ownership is higher and lower when formal governance is employed. Banks with high managerial ownership (low formal governance) target lower default risk. High managerial ownership, not formal governance, is associated with greater reliance on cash instead of equity to limit risk.
Interventions Aimed at Improving Reading Success: An Evidence-Based Approach

There is a consensus among researchers about the critical elements for effective reading instruction. These elements are the integration of explicit instruction in the alphabetic principle, reading for meaning, and opportunity to learn. These critical elements are present in classroom instruction that prevents reading difficulties as well as effective small-group and one-on-one interventions. Research on effective classroom instruction and reading interventions is described, and the case is argued that the most effective intervention is provided early-in kindergarten through 2nd grade-rather than after 3rd grade, and allows for sufficient intensity, duration, and supportiveness that no child is left behind. Policy implications for changes in (a) the way learning disabilities are identified and (b) the content of professional development of teachers are discussed.
Change in health status after rhinoplasty.

OBJECTIVE To assess the change in health status of patients undergoing rhinoplasty. DESIGN Retrospective mail-based questionnaire study using a validated post-intervention questionnaire specifically designed for otolaryngology surgery. SETTING District general hospital otolaryngology department. PATIENTS All patients (78 in total) undergoing rhinoplasty surgery between October 1998 and November 2003 were included in the study. MAIN OUTCOME MEASURE Glasgow Benefit Inventory, a validated post-intervention questionnaire specifically designed for otolaryngologic surgery. RESULTS The mean total Glasgow Benefit Inventory score was +20.0 (95% confidence interval [CI] 14.2-25.9), and the mean general, social, and physical subscale scores were +25.0 (95% CI 17.3-32.7), +10.2 (95% CI 4.4-16.0), and +9.9 (95% CI 2.7-17.0), respectively. CONCLUSIONS Our results show that the health status of patients undergoing rhinoplasty improved overall and according to each of the subscales used.
Nutrient digestibility and growth of local bull calves as affected by feeding urea and urease enzyme sources treated rice straw

The experiment was conducted for a period of 75 days to study the effect of treatment of straw with urea or with urea and a urease containing chick pea seed meal and midden soil on chemical composition of treated rice straw, feed intake of the animals, nutrients digestibility, body weight gain, and feed conversion efficiency. For the study twelve indigenous growing bulls aged approximately 20 months and weighing 115.16 ± 1.50 kg were divided into four groups having three animals in each group. The animals of group A received 3.5% urea treated fresh straw, group B received 3.5% urea treated ensiled straw, group C received 3.5% urea + 2.5% midden soil treated ensiled straw and group D received 3.5% urea + 2.5% chick pea treated ensiled straw. All the animals were supplied with treated rice straw, green grass and concentrate mixture. Rice straw treated with 3.5% urea resulted an improvement in crude protein content of rice straw from 3.33 to 7.70 and 8.10 % (without ensiling and ensiling) which was further increased by 8.20 and 9.50% with the addition of 2.5% midden soil and 2.5% chick pea seed meal at the time of treatment. Significantly higher (P<0.05) daily dry matter intake was observed in animals fed diet D (4.42) followed by diet C (4.39), diet B (4.34) and diet A (4.12). The total CP intake by the animals of D groups was significantly higher (P<0.01) than that of the animals receiving diet A, B and C. During the 75 days trail, the total live weight gains were 30.50, 35.17, 38.17 and 39.83 kg for bull calves fed diet A (3.5% urea treated straw without ensiling), diet B (3.5% urea treated straw with ensiling), diet C (3.5% urea + 2.5% midden soil treated straw) and diet D (3.5% urea + 2.5% chick pea seed meal treated straw) respectively. The daily live weight gains were 0.41, . 047, 0.51 and 0.53 kg in groups A, B, C and D respectively. Midden soil and chick pea seed meal addition with treated rice straw not only significantly (P<0.01) increased the coefficient of digestibility of DM, CP, and CF but also significantly (P<0.05) increased the coefficient of digestibility of OM, NFE than only urea treated straw (both without ensiling and ensiling). Addition of urease sources also increased (P<0.01) the digestible crude protein (DCP), digestible ether extract (DEE). Digestible nitrogen free extract (DNFE), digestible organic matter (DOM) and total digestible nutrients (TDN) contents were significantly (P<0.05) higher in diet D in comparison to diet A, B and C.

Functional Magnetic Resonance Imaging and Somatosensory Evoked Potentials in Rats with a Neonatally Induced Freeze Lesion of the Somatosensory Cortex

Brain plasticity is an important mechanism for functional recovery from a cerebral lesion. The authors aimed to visualize plasticity in adult rats with a neonatal freeze lesion in the somatosensory cortex using functional magnetic resonance imaging (fMRI), and hypothesized activation outside the primary projection area. A freeze lesion was induced in the right somatosensory cortex of newborn Wistar rats (n = 12). Sham-operated animals (n = 7) served as controls. After 6 or 7 months, a neurologic examination was followed by recording of somatosensory evoked potentials (SSEPs) and magnetic resonance experiments (anatomical images, fMRI with blood oxygen level–dependent contrast and perfusion-weighted imaging) with electrical forepaw stimulation under α-chloralose anesthesia. Lesioned animals had no obvious neurologic deficits. Anatomical magnetic resonance images showed a malformed cortex or hyperintense areas (cysts) in the lesioned hemisphere. SSEPs were distorted and smaller in amplitude, and fMRI activation was significantly weaker in the lesioned hemisphere. Only in a few animals were cortical areas outside the primary sensory cortex activated. The results are discussed in respect to an apparent absence of plasticity, loss of excitable tissue, the excitability of the lesioned hemisphere, altered connectivity, and a disturbed coupling of increased neuronal activity to the hemodynamic response.
Electrochemical oxidation of bisphenol-A from aqueous solution using graphite electrodes

Electrochemical oxidation of bisphenol-A (BPA) from aqueous solution using graphite electrodes has been investigated. The effect of the types and concentration of supporting electrolytes, initial pH and applied current density on the performance of the process were examined. During electrolysis, concentration of BPA has been monitored and determined using UV-vis spectra, chemical oxygen demand (COD) and energy consumption. NaCl has been considered as the best supporting electrolyte among the electrolytes used in the present study. Initial pH 5.0, higher concentration (0.01 to 0.1 M) of supporting electrolyte and higher applied current density (4 to 20 mA cm−2) facilitate the treatment process. The maximum COD removal of 78.3% has been achieved under the optimal experimental conditions such as NaCl concentration of 0.05 M, applied current density of 12 mA cm−2, initial pH 5.0 and electrolysis time of 120 min. When the energy consumption has been found to be decreasing with increasing NaCl concentration, it has increased with increasing applied current density. SEM–EDAX analysis has confirmed that the gases such as oxygen and chlorine are produced during the anodic oxidation in graphite anode. The result of UV-vis spectrum analysis confirms the degradation of BPA from aqueous solution at the end of the treatment.
Genome Update: AT content in sequenced prokaryotic genomes.

Genomes of the month – the good, the bad and the ugly The sequences of three bacterial genomes have been published in the month since the last Genome Update was written, with each representing bacteria with different and interesting lifestyles. The three genomes include that of a member of the acidophilus group of intestinal lactobacilli (a ‘good bacterium’), that of a pathogen that causes a highly contagious respiratory disease in cattle (a ‘bad bacterium’, certainly from the perspective of the ranchers) and that of a bacterial predator that invades and consumes other bacteria (‘ugly’ from the point of view of its prey).
Ability of the Digene Hybrid Capture II Test To Identify Chlamydia trachomatis and Neisseria gonorrhoeae in Cervical Specimens

ABSTRACT The Digene Hybrid Capture II (HCII CT/GC) test is a combination test designed to detect Chlamydia trachomatis andNeisseria gonorrhoeae in a single specimen. It is a nucleic acid hybridization test which uses signal amplification to increase sensitivity. We compared its performance to that of culture on cervical specimens from 1,370 women. Direct fluorescent-antibody assay was used to resolve discrepant results for C. trachomatis. Samples were collected with a proprietary cervical brush or with endocervical swabs. The HCII CT/GC test proved to be sensitive and specific in detecting these organisms. Compared to N. gonorrhoeaeculture, it had a sensitivity of 93% (87/94) and a specificity of 98.5% (1,244/1,263). Compared to C. trachomatis culture, the sensitivity was 97.7% (129/132) and specificity was 98.2% (1,216/1,238). Testing of some specimens with discrepant results by PCR suggested that the test would actually prove to be even more specific if it were compared to a nucleic acid amplification test (NAAT). The sensitivity of C. trachomatis culture was somewhat less, at 88.6% (117/132). The endocervical brush appeared to be better than Dacron swabs for collecting specimens. The HCII CT/GC test offers an attractive format that allows simultaneous detection of C. trachomatis and N. gonorrhoeae with a single specimen. An initial positive result is followed by repeat tests with probes to identify chlamydiae or gonococci. This test is more sensitive than C. trachomatis culture and is at least as sensitive as culture for gonococci. It deserves further evaluation and comparison with NAATs and may well offer an attractive alternative for diagnosis and screening of these infections.
ALBUMIN ADMINISTRATION COMBINED WITH PHOTOTHERAPY IN TREATMENT OF HYPERBILIRUBINAEMIA IN LOW‐BIRTH‐WEIGHT INFANTS

ABSTRACT. Ebbesen, F. , and Brodersen, R. (Department of Neonatology, Rigshospitalet, Copenhagen and Institute of Medical Biochemistry, Aarhus, Denmark). Albumin administration combined with phototherapy in treatment of hyperbilirubinaemia in low‐birth‐weight infants. Acta Paediatr Scand, 70:649,. –Fifty‐nine jaundiced light treated newborn infants with low birth weight were studied. At onset of phototherapy 30 infants received 1 g human serum albumin per kg body weight as a 9 % solution containing sodium caprylate and N‐acetyltryptophan as stabilizers. 29 infants did not receive human serum albumin and served as controls. Blood samples were taken before initiation of the therapy and again 24 and 48 h thereafter, and the following determinations were made: Serum concentrations of unconjugated bilirubin, albumin, reserve albumin for binding of bilirubin by the [l4C]‐MADDS method, packed cell volume and pH. Before infusion of albumin it was found that the binding fraction of serum albumin, i.e. the sum of the serum concentrations of bilirubin‐albumin and reserve albumin, constituted about half of the total serum albumin concentration. The other half was non‐binding, in agreement with previous findings in neonates. The effect of albumin therapy was mainly an unexpected increase of the non‐binding fraction of serum albumin, while the increase of the serum reserve albumin concentration was small and the concentration of bilirubin‐albumin was not changed.
HISTORICAL REVIEW OF INTERSTITIAL PROSTATE BRACHYTHERAPY

In the recent years, interstitial brachytherapy implantation has become the treatment of choice for early stage prostate cancer patients (1, 2, 3). Popularity of this modality is most likely due to the fact that five-and ten-year disease control rates of brachytherapy are equal to those of the surgical and external radiation therapy, whereas, the toxicity and side-effects are perceived to be lower (4,5). It has been estimated that up to 50% of patients with early stage prostate cancer are now treated with ultrasound-guided transperineal interstitial brachytherapy (3-7) with I-125 or Pd-103 radioactive seeds. The principal advantage of this technique is that the seeds can deliver a substantially higher radiation dose to the prostate and less radiation dose to the surrounding tissue compared with external beam irradiation (8, 9). Iodine-125, Pladium-103, and most recently introduced Cs-131 are the most suitable radiation sources for this treatment modality. These sources emit low energy photons and the dose falls quickly with the distance and therefore, seeds deliver low dose to the adjacent rectum and bladder (10-14).
The impact of reference effects on online purchase intention of agricultural products: The moderating role of consumers' food safety consciousness

Purpose The purpose of this paper is to analyze the impact of reference effects on online purchase intention (OPI) of agricultural products in B2C context and to examine how consumers’ food safety consciousness (FSC) moderates that impact. Design/methodology/approach An empirical survey was used to test the hypotheses. Data were collected from a total of 297 online consumers in China. A structural equation modeling is utilized to assess the relationships proposed in the research model. Findings The findings of this study show that reference effects have a significant impact on OPI of agricultural products. Both perceived value (PV) and perceived risk (PR) play a mediating role in the relations between reference effects and OPI, but the mediating effect of the PV is found to be significantly greater than that of the PR. Consumers’ FSC significantly and positively moderates the impact of reference effects on OPI, meaning that the more attention consumers pay to food safety, the greater the impact of reference effects on OPI will become. Research limitations/implications First, this study mainly analyzes the positive impact of reference effects on OPI. Future research could discuss the negative impact of reference effects and compare the differences between them. Second, this study only takes the PV and PR as mediators into the research model. Future research could consider adding trust, attitude, and other variables and further explore and clarify the influencing mechanism between reference effects and OPI. Third, this study examines the moderating role of consumers’ FSC but does not fully discuss the moderating role of product categories. Further research could compare the influence of reference effects among multiple product categories. Practical implications This study provides valuable insights for agricultural enterprises and online vendors that reference effects are one of the most important factors to influence OPI. It suggests to agricultural enterprises and online vendors that reference effects can be used as a new instrument to influence consumers’ online purchase decisions. Originality/value This study for the first time defines reference effects in an online setting and introduces the perspective of reference effects to establish a theoretical model to explain consumers’ OPI of agricultural products. The study reveals the influencing mechanism of reference effects on OPI and thus enriches the theory of online purchase behavior.
Ccdc13 is a novel human centriolar satellite protein required for ciliogenesis and genome stability

ABSTRACT Here, we identify coiled-coil domain-containing protein 13 (Ccdc13) in a genome-wide RNA interference screen for regulators of genome stability. We establish that Ccdc13 is a newly identified centriolar satellite protein that interacts with PCM1, Cep290 and pericentrin and prevents the accumulation of DNA damage during mitotic transit. Depletion of Ccdc13 results in the loss of microtubule organisation in a manner similar to PCM1 and Cep290 depletion, although Ccdc13 is not required for satellite integrity. We show that microtubule regrowth is enhanced in Ccdc13-depleted cells, but slowed in cells that overexpress Ccdc13. Furthermore, in serum-starved cells, Ccdc13 localises to the basal body, is required for primary cilia formation and promotes the localisation of the ciliopathy protein BBS4 to both centriolar satellites and cilia. These data highlight the emerging link between DNA damage response factors, centriolar and peri-centriolar satellites and cilia-associated proteins and implicate Ccdc13 as a centriolar satellite protein that functions to promote both genome stability and cilia formation.
Chitinases from Vibrio: activity screening and purification of chiA from Vibrio carchariae

Fourteen species of Vibrio were screened for chitin‐induced chitinase activity in culture medium. V. carchariae, V. alginolyticus 283 and V. campbellii showed high levels of activity. Screening on agar plates containing swollen chitin showed high levels of chitinase activity by the same three species, and also by V. fischeri and V. alginolyticus 284. An affinity purification procedure was developed for the chitinase from V. carchariae. The purified chitinase was active as a monomer with Mr 63 000–66 000, and displayed activity toward polymeric chitin from acetylated chitosan or from crab shells. N‐terminal sequence analysis and immunological cross‐reactivity confirmed that the enzyme belongs to the group A/chiA family of bacterial chitinases.
Single molecule force spectroscopy on G-quadruplex DNA.

Interest in guanine (G) quadruplexes[1] has intensified over the past decade because they are found in human telomeres,[2] the chromosome ends that govern gene stability, and other parts of the genome, especially in promoters. [3] They have been shown to inhibit the activity of telomerase, an enzyme which maintains the proper length of telomere DNAs and is over-expressed in many types of cancer. [4] As such, the G-quadruplex DNA has been an attractive target for cancer therapy. [5] Despite the wide interest in the topology of G-quadruplexes, their physical properties are not well-understood. [6] There are large differences between the kinetic data obtained in solution using fluorescence and on surfaces using surface plasmon resonance (SPR) approaches,[7] possibly due to destabilization by fluorophore labelling[7a-c] and surface hindrance in the indirect hybridization based SPR approach. [7d] The kinetics and thermodynamics are expected to be different for G-quadruplexes formed from uni-, bi-, and tetra-molecular DNA strands. Furthermore, G-quadruplexes formed from a single DNA strand may have different conformations,[6.7] where minor changes in the DNA sequence may result in significant differences in their thermodynamic properties.

Cue reactivity, habituation, and eating in the absence of hunger in children with loss of control eating and attention‐deficit/hyperactivity disorder

OBJECTIVE Childhood loss of control (LOC) eating and attention-deficit/hyperactivity disorder (ADHD) are highly comorbid conditions and present with disordered eating behaviors, such as overeating. This study sought to delineate shared and specific abnormalities in physiological, cognitive-motivational, and behavioral components of food-specific impulsivity in children with LOC eating and ADHD. Specifically, children's reactivity and habituation to food and eating in the absence of hunger were examined. METHODS Within this community-based study, four groups of 8-13-year-old children with LOC eating (n = 24), ADHD (n = 32), comorbid LOC eating/ADHD (n = 9), and matched controls (n = 34) received a standard laboratory test meal to establish satiety and were then exposed to their favorite snack food in a cue exposure/reactivity trial, while salivation and desire to eat were repeatedly assessed. Subsequently, they were offered a variety of snack foods ad libitum. RESULTS Children with LOC eating, ADHD, and LOC/ADHD did not differ from controls in salivary reactivity and habituation to food cues. Children with LOC eating and ADHD showed greater cue reactivity of the desire to eat than controls, but groups did not differ in its longer-term increments. At free access, only children with LOC/ADHD consumed significantly more energy than controls. Longer-term increments of desire to eat predicted greater energy intake beyond LOC/ADHD group status. DISCUSSION Desire to eat among children with comorbid LOC eating and ADHD was associated with overeating in the absence of hunger, which may contribute to excess weight gain. Delineation of the specific features of childhood LOC eating versus ADHD warrants further study.
Substantia Nigra Hyperechogenicity for the Early Detection of ParkinsonÃ¢ÂÂsDisease

Hyperechogenicity of the substantia nigra (SN+) is an imaging marker which may be detected in individuals at risk for Parkinson’s disease (PD). In this short commentary, the evidence of SN+ as a risk marker for PD including its predictive value, stability and the limitations in assessment are discussed based on the current literature.
