    Nasal tuberculosis is a rare clinical entity which mainly presents in elderly people. Nasal tuberculosis has always been considered to be secondary to tuberculosis of the lungs, and in rare instances it is a primary infection, usually when mycobacteria are inhaled. We describe the case of a 10-year-old girl who was successfully treated for primary nasal tuberculosis. This patient is one of the very few children who have been reported to have primary nasal tuberculosis. PMID:27366187

    Parathyroid carcinoma (PC) is a rare cause of hypercalcaemia in children. Only 7 cases of PC have been reported so far in the world journal. The authors report the 8th case of parathyroid carcinoma in children less than 16 years of age. A 10 year old girl presented with difficulty in walking, dorsiflexion and ulnar deviation of both wrist joints and occasional pain in the central abdomen of about two years duration. Biochemical investigations revealed serum calcium 12.2 mg/dL (normal 9-11 mg/dL), serum alkaline phosphate 4992 U/L (normal 50-136 U/L), PTH (parathyroid hormone) 2217 pg/ml (normal 9-80 pg/ml). Parathyroid scintigraphy localized the lesion in the left parathyroid gland. X-ray showed bilateral coxa vera, genu valgus deformity and multiple stress fractures in both wrist joints. Histopathology confirmed PC with capsular and vascular invasion.

    Scurvy, or hypovitaminosis C, is an uncommon condition that exists today primarily within certain unique populations-particularly the elderly subjects, patients with neurodevelopmental disabilities or psychiatric illnesses, or others with unusual dietary habits. Vitamin C is an essential nutrient in the human body, and is important in synthesizing collagen factor whose faulty production is responsible for most of the clinical manifestations of scurvy. These clinical manifestations can include dystrophic or corkscrew hairs, gingival hyperplasia, and weakened blood vessel walls, causing bleeding in the skin, joints, and other organs. Although rare in the Unites States, the presence of scurvy should not be forgotten because of its presence among susceptible populations. Moreover, with its diagnosis, treatment and cure is one of the simplest in modern medicine. We report a case of scurvy in a 10-year-old autistic child.

    Purpose: The purpose of this study is the development of reference pediatric phantoms for 5- and 10-year-old children to be used for the calculation of organ and tissue equivalent doses in radiation protection. Methods: The study proposes a method for developing anatomically highly sophisticated pediatric phantoms without using medical images. The 5- and 10-year-old male and female phantoms presented here were developed using 3D modeling software applied to anatomical information taken from atlases and textbooks. The method uses polygon mesh surfaces to model body contours, the shape of organs as well as their positions, and orientations in the human body. Organ and tissue masses comply with the corresponding data given by the International Commission on Radiological Protection (ICRP) for the 5- and 10-year-old reference children. Bones were segmented into cortical bone, spongiosa, medullary marrow, and cartilage to allow for the use of micro computer tomographic ({mu}CT) images of trabecular bone for skeletal dosimetry. Results: The four phantoms, a male and a female for each age, and their organs are presented in 3D images and their organ and tissue masses in tables which show the compliance of the ICRP reference values. Dosimetric data, calculated for the reference pediatric phantoms by Monte Carlo methods were compared with corresponding data from adult mesh phantoms and pediatric stylized phantoms. The comparisons show reasonable agreement if the anatomical differences between the phantoms are properly taken into account. Conclusions: Pediatric phantoms were developed without using medical images of patients or volunteers for the first time. The models are reference phantoms, suitable for regulatory dosimetry, however, the 3D modeling method can also be applied to medical images to develop patient-specific phantoms.

    2015-01-01

    Choroidal osteoma is a rare, benign tumor, usually diagnosed in healthy adult women in their second or third decade of life. Though its etiology and pathogenesis are unclear, it is usually diagnosed due to its typical clinical features of yellowish-orange colored subretinal lesion at posterior pole and a dense echogenic plaque persisting even in lower gains on B-scan ultrasonography. Mostly unilateral (79%), the median age of diagnosis is 26 years. It is relatively rare in children. We report a case of choroidal osteoma in a 10-year-old boy. PMID:26586966

    Incontinentia pigmenti is a rare genodermatosis in which the skin involvement occurs in all patients. Additionally, other ectodermal tissues may be affected such as the central nervous system, eyes, hair, nails and teeth. The disease has an X-linked dominant inheritance pattern. But in our case, there was a mutation in the body cells due to incontinentia pigmenti. The dermatological findings occur in four successive phases. We report the case of a 10-year-old female presented cutaneous, dental and ophthalmic characteristic with 3 years follow-up. Dental anomalies such as hypodontia, peg-shaped anterior teeth, malformed primary and permanent teeth, and delayed eruption were seen in our patient.

    Peroral endoscopic myotomy (POEM) is a new endoscopic treatment for achalasia with very good short-term results in adults. Data about POEM in pediatric patients are missing. We present the case of a 10-year-old male patient with type I (classic) achalasia, successfully treated with POEM. The procedure was accomplished in a similar fashion to the technique used in adults. Short-term results were fine, with a complete control of dysphagia and absence of reflux. We suggest that POEM is a suitable option in pediatric patients—similar to adults—but long-term results must be awaited. PMID:26171309

    We describe a 10 year old boy with organising pneumonia associated with acute Mycoplasma pneumoniae infection. The diagnosis of organising pneumonia was made by open lung biopsy and the M pneumoniae infection was proven serologically. Antibiotic and long term corticosteroid treatment resulted in steadily improving pulmonary function monitored by spirometry. The introduction of anti-inflammatory treatment with NSAIDs/immunosuppressive agents in order to spare steroids was well tolerated and resulted in further improvement of the pulmonary function. To our knowledge this is the first documented case of Mycoplasma pneumoniae associated organising pneumonia to be reported in a child.

    Neurocysticercosis is the most common parasitic infection of the central nervous system caused by larvae of Taenia solium. Spinal cysticercosis is an uncommon site of cysticercal infection, and isolated intramedullary involvement is even rarer. We present a case of 10-year-old girl who presented with gradual onset paraparesis with sensory loss and bowel and bladder incontinence. Magnetic resonance imaging (MRI) of spine revealed a cystic lesion with mural nodule (scolex) which was diagnostic for cysticercosis. Patient was treated with antihelminthic, which led to marked clinico-radiological improvement. PMID:21977090

    Effects of characteristics of science classrooms on the science achievement of students were examined in the context of a simple model. The model incorporated prior attributes of the students in terms of home background, sex, and verbal and quantitative ability. The model was estimated by means of partial least squares multivariate procedures using data for 10-year-old Queensland students from the Second International Science Study. The results demonstrated the dominant influence of home background and verbal/mathematical ability. Female students tended to have lower scores after allowing for the influence of the other variables in the model. Students who stated that there were more student initiated activities in their science lessons tended to have lower achievement.

    A 10 year old girl with diarrhea, abdominal pain, weight loss and fever of one month and a half of evolution. Analytical and sonographic findings raised the possibility of inflammatory bowel disease. Endoscopy and histology showed findings consistent with Crohn's disease. Treatment was initiated with mesalazine and exclusive enteral nutrition. Later corticosteroid treatment, immunosuppressive drugs and ursodeoxycholic acid were added due to cholestasis and persistent hypergammaglobulinemia. Magnetic resonance cholangiography and liver biopsy confirmed the diagnosis of concomitant primary sclerosing cholangitis. The association between Crohn's disease and primary sclerosing cholangitis is rare, predominantly in males between 20 and 40 years old and it presents a great clinical variability. The confirmation of the diagnosis requires magnetic resonance cholangiography or endoscopic retrograde cholangiopancreatography. The prognosis is poor and there is no treatment to slow the progression of the disease.

    2009-07-01

    The genetic and environmental etiology of high math performance (at or above the 85%tile) was examined in a population-based sample of 10-year-old twins (nMZ = 1,279, nDZ = 2,305). Math skills were assessed using a web-based battery of math performance tapping skills related to the UK National Math Curriculum. Probandwise concordance rates and liability threshold models indicated that genetic and shared environmental influences were significant, and that these estimates were generally similar to those obtained across the normal range of ability and did not vary significantly by gender. These results suggest that the genetic and environmental influences at the high end of ability are likely to be continuous with those that affect the entire range of math performance across all children irrespective of gender.

    Recently, the incidence of pertussis has been increasing; however, reports on mixed infection of pertussis with other respiratory pathogens are rare in highly immunized populations. We report the case of a 10-year-old girl who presented with cough, post-tussive emesis, and fever. She was subsequently diagnosed with bronchopneumonia. Although she had received five doses of diphtheria-tetanus-acellular pertussis vaccine, polymerase chain reaction of her nasopharyngeal aspirate confirmed Bordetella pertussis infection. In addition, serologic testing for Mycoplasma pneumoniae was also positive. The patient was treated with roxithromycin without any complications. This is the first report of mixed B. pertussis and M. pneumoniae infection in Korea. To avoid under-diagnosis, pertussis should be considered in patients with chronic cough even when other respiratory pathogens have been documented. PMID:26483996

    Purpose To determine the amount and time course of binocular visual acuity improvement during treatment of bilateral refractive amblyopia in children age 3 to <10 years old Design Prospective, multicenter noncomparative intervention Methods 113 children (mean age = 5.1 years) with previously untreated bilateral refractive amblyopia were enrolled at 27 community- and university-based sites and were provided optimal spectacle correction. Bilateral refractive amblyopia was defined as 20/40 to 20/400 best-corrected binocular acuity in the presence of ≥ 4.00 D hypermetropia by spherical equivalent and/or ≥ 2.00 D astigmatism in each eye. Best-corrected binocular and monocular visual acuities were measured at baseline and at 5, 13, 26 and 52 weeks. The primary study outcome was binocular acuity at one year. Results Mean binocular visual acuity improved from 0.50 logMAR (20/63) at baseline to 0.11 logMAR (20/25) at one year (mean improvement 3.9 lines, 95% confidence interval [CI] = 3.5 to 4.2). Mean improvement at one year for the 84 children with baseline binocular acuity of 20/40 to 20/80 was 3.4 lines (95% CI = 3.2 to 3.7) and for the 16 children with baseline binocular acuity of 20/100 to 20/320 was 6.3 lines (95% CI = 5.1 to 7.5). The cumulative probability of binocular acuity of 20/25 or better was 21% at 5 weeks, 46% at 13 weeks, 59% at 26 weeks, and 74% at 52 weeks. Conclusions Treatment of bilateral refractive amblyopia with spectacle correction improves binocular visual acuity in children age 3 to <10 years old, with most improving to 20/25 or better within one year.

    2015-01-01

    BACKGROUND Preventing obesity is a worldwide public health priority. In vulnerable children living in obesogenic environments, with easy access to high-caloric food, alterations in inhibitory control functions might favor excessive food intake and affect energy regulation. We hypothesized that overweight/obese children would present lower inhibitory control in comparison to normal weight children. METHODS We measured inhibitory control functions in 93 otherwise healthy overweight/obese and 92 normal weight 10-year-old children using the Stroop test and the Go/No-Go task. Event-related potentials were recorded during the Go/No-Go task. RESULTS Overweight/obese children showed slower reaction times (1248.6 ms (95% confidence interval (CI): 1182.9–1314.3) vs 1149.0 ms (95% CI: 1083.0–1215.1)) on the Stroop test, higher reaction time variability (0.25 (95% CI: 0.22–0.27) vs 0.21 (95% CI: 0.19–0.24)) on the Go/No-Go task and decreased P300 amplitude (4.1 µV (95% CI: 3.0–5.2) vs 6.4 µV (95% CI: 5.2–7.6)) on event-related potentials compared with normal weight children. CONCLUSIONS Our results indicate altered inhibitory control functions in otherwise healthy overweight/obese children, which might contribute to their excessive food consumption. PMID:25869603

    Myxoma is a benign connective tissue tumor that is most commonly found in the heart. Because myxoma of the external ear is extremely rare, its diagnosis may be easily delayed or it may be misdiagnosed as another disease. Moreover, because it can be a part of Carney complex (autosomal dominant syndrome), its correct diagnosis is very important. We experienced a 10-year-old girl who had a mass on the posterior surface of the tragus at the entrance of the left ear canal. Fine-needle aspiration revealed mucoid content of the cystic mass, but its cytology did not confirm the diagnosis. The whole mass was surgically removed, and the diagnosis was confirmed as myxoma with a stellate spindle cell proliferation in the hypocellular matrix. Thorough examination failed to determine any presentation of Carney complex, and her final diagnosis was isolated myxoma of the external auditory canal. This is the first reported study regarding myxoma of the external auditory canal in the Korean literature. PMID:26915162

    Objective Pregnancies complicated by diabetes mellitus impair offspring memory functions during infancy and early childhood. The purpose of this study was to investigate the long term consequences of such pregnancies on memory and memory-related brain regions in 10-year-old children. Method Nineteen (19) children of diabetic mothers (CDMs) and thirty-five (35) children of non-diabetic mothers participated in this 10 year follow-up study. Memory performance was assessed using a continuous recognition memory task during which children made old/new judgments in response to pictures of concrete and abstract objects presented after different lags or delays. In addition, the volume of the hippocampal formation was measured using high resolution structural images. Results At 10 years of age, recognition memory performance of CDMs did not differ from children of non-diabetic mothers. Similarly, the volume of the hippocampal formation did not differ between groups. However, the size of the hippocampal formation in CDMs predicted the time those children needed to provide accurate responses in the continuous recognition memory task. Conclusion CDMs do not show memory impairments by 10 years of age, despite evidence for such impairments early in life. However, subtle differences in underlying neural processes may still be present. These results have important implications for long-term cognitive development of CDMs. PMID:26348971

    Lederman, Sheri G.

    Executive function (EF) is an umbrella term used to identify a set of discrete but interrelated cognitive abilities that enable individuals to engage in goal-directed, future-oriented action in response to a novel context. Developmental studies indicate that EF is predictive of reading and math achievement in middle childhood. The purpose of this study was to identify the association between EF and science achievement among normally developing 10 year olds. A sample of fifth grade students from a Northeastern suburban community participated in tests of EF, science, and intelligence. Consistent with adult models of EF, principal components analysis identified a three-factor model of EF organization in middle childhood, including cognitive flexibility, working memory, and inhibition. Multiple regression analyses revealed that executive function processes of cognitive flexibility, working memory, and inhibition were all predictive of science performance. Post hoc analyses revealed that high-performing science students differed significantly from low-performing students in both cognitive flexibility and working memory. These findings suggest that complex academic demands specific to science achievement rely on the emergence and maturation of EF components.

    The association of attention-deficit-hyperactivity disorder (ADHD) with bullying in the peer group in school was studied in an entire population of 577 fourth graders (10-year-olds) in one municipality in Stockholm, Sweden. The schoolchildren were screened for ADHD in a two-step procedure that included Conners'ratings of behavioural problems: teacher and parent interviews in a first step; and a clinical assessment in the second. Information about bullying was collected from the children themselves in a classroom questionnaire. Five-hundred and sixteen children (89.4%; 252 females, 264 males), for whom there was information from all data sources, were included in the study population. Conners'ratings that were collected from parents early in first grade were available for 382 of these children. Hypotheses were tested by multivariate analyses with adjustment for sex and parental education. Pervasive ADHD was diagnosed in 9.5% (95% confidence interval [CI] 5.6-12.8) of the males and 1.6% (CI 0.1-3.1) of the females. ADHD was associated with bullying other students (adjusted odds ratios (OR) 3.8 [CI 2.0-7.2]) as well as being bullied (often, OR 10.8 [CI 4.0-29.0]; sometimes, OR 2.9 [CI 1.5-5.7]). Bullying other students in fourth grade was associated with high scores in parental reports of behavioural problems at entry into first grade, suggesting a causal link to the ADHD syndrome. Being bullied, on the other hand, was not linked to behavioural problems at school entry. This study demonstrates a connection between ADHD and bullying in the peer group at school. Evaluation and treatment strategies for ADHD need to include assessment and effective interventions for bullying. Evaluation of ADHD should be considered in children involved in bullying.

    Objective Epidemiological evidence shows an inverse relationship between sleep duration and overweight/obesity risk. However, there are few polysomnographic studies that relate the organization of sleep stages to pediatric overweight (OW). We compared sleep organization in otherwise healthy OW and normal weight (NW) 10-year-old children. Subjects Polysomnographic assessments were performed in 37 NW and 59 OW children drawn from a longitudinal study beginning in infancy. Weight and height were used to evaluate body-mass index (BMI) according to international criteria. Non-REM (NREM) sleep (stages N1, N2 and N3), rapid eye movement (REM) sleep (stage R), and wakefulness (stage W) were visually scored. Sleep parameters were compared in NW and OW groups for the whole total sleep period (SPT) and for each successive third of it using independent student t-tests or non-parametric tests. The relationship between BMI and sleep variables was evaluated by correlation analyses controlling for relevant covariates. Results The groups were similar in timing of sleep onset and offset, and sleep period time. BMI was inversely related to total sleep time (TST) and sleep efficiency. OW children showed reduced TST, sleep efficiency, and stage R amount, but higher stage W amount. In analysis by thirds of the SPT, the duration of stage N3 episodes, was shorter in the first third and longer in the second third in OW children, compared with NW children. Conclusions Our results show reduced sleep amount and quality in otherwise healthy OW children. The lower stage R amount and changes involving stage N3 throughout the night suggest that OW in childhood is associated with modifications not only in sleep duration, but also in the ongoing nighttime patterns of NREM sleep and REM sleep stages.

    BACKGROUND/OBJECTIVES Diet plays an important role in growth and development of children. However, dietary intakes of children living in either rural or urban areas can be influenced by household income. This cross-sectional study examined energy, nutrient and food group intakes of 749 urban children (1-10 years old) by household income status. SUBJECTS/METHODS Children's dietary intakes were obtained using food recall and record for two days. Diet adequacy was assessed based on recommended intakes of energy and nutrients and food group servings. RESULTS For toddlers, all nutrients except dietary fiber (5.5 g) exceeded recommended intakes. Among older children (preschoolers and school children), calcium (548 mg, 435 mg) and dietary fiber (7.4 g, 9.4 g) did not meet recommendations while percentage of energy from total fat and saturated fats exceeded 30% and 10%, respectively. The mean sodium intakes of preschoolers (1,684 mg) and school children (2,000 mg) were relatively high. Toddlers in all income groups had similar energy and nutrient intakes and percentages meeting the recommended intakes. However, low income older children had lowest intakes of energy (P < 0.05) and most nutrients (P < 0.05) and highest proportions that did not meet recommended energy and nutrient intakes. For all food groups, except milk and dairy products, all age groups had mean intakes below the recommended servings. Compared to middle and high income groups, low income preschoolers had the lowest mean intake of fruits (0.07 serving), meat/poultry (0.78 serving) and milk/dairy products (1.14 serving) while low income toddlers and school children had the least mean intake of fruits (0.09 serving) and milk/dairy products (0.54 serving), respectively. CONCLUSION Low socioeconomic status, as indicated by low household income, could limit access to adequate diets, particularly for older children. Parents and caregivers may need dietary guidance to ensure adequate quantity and quality of home

    Background and Aims The increase in overweight and obese children may be linked to increased rates of dyslipidaemia. The aim was to assess the prevalence of dyslipidaemia and associated risk factors among the Northern Mexican child population. Methods and Results Four hundred and fifty-one subjects aged between 2 and 10 (47.5% girls) took part in the Nuevo León State Survey of Nutrition and Health 2011–2012. According to the 2011 Expert Panel on Integrated Guidelines for Cardiovascular Health and Risk Reduction in Children and Adolescents, serum lipid levels (mg/dL) were categorized into three subgroups (acceptable, borderline-high/low or high/low) as follows: TChol: acceptable <170, borderline-high 170–199, high ≥200; LDL-chol: acceptable <110, borderline-high 110–129, high ≥130; non-HDL-chol: acceptable <120, borderline-high 120–144, high ≥145; HDL-chol: acceptable >45, borderline-low 40–45, low <40; and TG: acceptable <75, borderline-high 75–99, high ≥100 in ≤9 year-old children, and acceptable <90, borderline-high 90–129, and high ≥130 in 10 year-old children. The overall prevalence of borderline-high + high TG, non-HDL-chol, TChol, and LDL-chol was 63.0%, 44.1%, 43.5%, and 29.9%, respectively. The overall prevalence of borderline-low + low HDL-chol was 46.3%. The overall frequency of dyslipidaemia was 54.3%. Thirteen children (2.9%) had all five symptoms of dyslipidaemia. The most common dyslipidaemia was high TG in combination (26.2%) and in isolation (10.6%). Conclusions Half of the children had at least one abnormal lipid concentration. A high TG level was the most frequent dyslipidaemia. Obesity was associated with the occurrence of at least one abnormal lipid level. These findings emphasize the need to pay further attention to the prevention of cardiovascular disease and obesity from an early age. PMID:25793380

    Limbic encephalitis is a rare neurological disorder that may be difficult to recognize. Clinical features include memory impairment, temporal lobe seizures and affective disturbance. We report the case of a 10-year-old girl with type 1 diabetes mellitus that presented with seizures, depressed mood and memory changes. The diagnosis of glutamic acid decarboxylase 65 (GAD65) mediated limbic encephalitis relied on cerebral magnetic resonance imaging lesions and high serological and cerebrospinal fluid GAD65-antibodies titers. High-dose steroidal therapy was started with clinical improvement. Relapse led to a second high-dose steroid treatment followed by rituximab with remission. A correlation between serum GAD65-antibodies levels and symptoms was found, demonstrating GAD65-antibodies titers may be useful for clinical follow-up and immunotherapy guidance. This report raises awareness of this serious neurological condition that may be associated with type 1 diabetes, underlining the importance of an early diagnosis and prompt treatment for a better prognosis.

    Regional odontodysplasia (RO) is an uncommon, developmental anomaly of the dental hard tissues that affects ectodermal and mesodermal dental components with characteristic clinical and radiographic findings. Clinically, RO affects a particular segment in either or both dentitions in the maxilla or mandible or both jaws. Radiographic features have consistently demonstrated thin and defective layers of enamel and dentine, resulting in a faint, fuzzy outline, creating a ghost-like appearance. The RO etiology is uncertain; numerous factors have been suggested and considered as local trauma, irradiation, hypophosphatasia, hypocalcemia, hyperpyrexia. A case of RO in a 10-year-old girl whose chief complaint were forwardly placed upper front teeth and the absence of eruption of permanent teeth. Clinical and radiographic features are described.

    Cyanotic breath-holding spells are generally benign and resolve spontaneously by 4 to 5 years of age. Treatment with iron and other drugs has been employed in selected cases with very frequent and severe episodes. We describe a 10-year-old boy with recent-onset cyanotic breath-holding spells that were activity limiting. He was unable to participate in physical activities with his peers as any argument or emotional upset provoked these spells. Treatment with oral iron and piracetam was ineffective. However, treatment with oral theophylline produced dramatic amelioration of symptoms, and he was once again able to participate in play activities with his peers. We believe that general central nervous system stimulant and respirogenic effects of theophylline were instrumental in control of symptoms in our child.

    OBJECTIVE To review the current information on medical complications, psychological implications, and legislative issues related to body piercing, a largely unregulated industry in the United States. METHODS We conducted a MEDLINE search of English language articles from 1966 until May 1998 using the search terms “body piercing” and “ear piercing.” Bibliographies of these references were reviewed for additional citations. We also conducted an Internet search for “body piercing” on the World Wide Web. MAIN RESULTS: In this manuscript, we review the available body piercing literature. We conclude that body piercing is an increasingly common practice in the United States, that this practice carries substantial risk of morbidity, and that most body piercing in the United States is being performed by unlicensed, unregulated individuals. Primary care physicians are seeing growing numbers of patients with body pierces. Practitioners must be able to recognize, treat, and counsel patients on body piercing complications and be alert to associated psychological conditions in patients who undergo body piercing.

    The aim of this study was to assess the reproducibility and validity of a non-quantitative 28-item food frequency questionnaire (FFQ). Children aged 9-10 years (n = 50) from three schools in Dunedin, New Zealand, completed the FFQ twice and a four-day estimated food diary (4DEFD) over a two-week period. Intraclass correlation coefficients (ICC) and Spearman's correlation coefficients (SCC) were used to determine reproducibility and validity of the FFQ, respectively. Weekly intakes were estimated for each food item and aggregated into 23 food items/groups. More than half of the food items/groups (52.2%) had an ICC ≥0.5. The median SCC between FFQ administrations was 0.66 (ranging from 0.40 for processed meat to 0.82 for sweets and non-dairy drinks). Cross-classification analysis between the first FFQ and 4DEFD for ranking participants into thirds showed that breakfast cereals had the highest agreement (54.0%) and pasta the lowest (34.0%). In validity analyses, 70% of food items/groups had a SCC ≥0.3. Results indicate that the FFQ is a useful tool for ranking children according to food items/groups intake. The low respondent burden and relative simplicity of the FFQ makes it suitable for use in large cohort studies of 9-10 year-old children in New Zealand. PMID:27164137

    Previous studies have emphasized the importance of rater issues in studying the etiology of variation in internalizing and externalizing problems in children. Earlier results indicate only moderate agreement between parents, and assume that parents assess a specific aspect of their child's behavior. In comparable samples of younger children, additive genetic effects are the main factor explaining individual differences in both internalizing and externalizing behavior. It is unknown whether this pattern of rater influences and variance decomposition will be consistent in older children. Child Behavior Checklists (Achenbach, 1991), completed by both parents, were collected in a sample of 2956 Dutch 10-year-old twin pairs. The etiology of individual differences in internalizing and externalizing syndromes was examined using a model that corrected for possible rater bias, rater-specific effects and unreliability. The best fitting model suggested that disagreement between the parents is not merely the result of unreliability and/or rater bias, but each parent also provides specific information from his/her own perspective on the child's behavior. Significant influences of additive genetic, shared environmental and unique environmental factors were found for internalizing and externalizing syndromes.

    Serenoa repens, commonly known as saw palmetto, is the sole species currently classified in the genus Serenoa. The plant is a low shrubby palm that is native of West Indies, and it grows in the coastal lands of North America and other European mediterranean countries. Its fruits contain high concentrations of fatty acids and phytosterols. S. repens extracts have been studied for the symptomatic treatment of benign prostatic hyperplasia. Recently, they have been proposed to treat androgenic alopecia and other hair disorders. We report a new case of hot flashes in a 10-year-old girl using a food supplement containing the extract of S. repens for the treatment of hirsutism. When the girl discontinued the treatment, the hot flashes stopped. A 'rechallenge' of the supplement was tried and symptoms reappeared. About 4 months after starting therapy, the girl experienced menarche. Exposure to the plant-derived product could be responsible for the appearance of menarche. In our opinion, use of phytotherapeutic agents in pediatric patients should be associated to a better evaluation of benefit/risk profile taking in account the physiological changes that occurs at different ages in this subgroup of population.

    Background: Variations in the structure of teeth have always been a great curiosity to the dentist from the scientific and practical point of view. Aim: To evaluate the prevalence of a few aberrant morphological features namely, cusp of Carabelli in primary maxillary second molar and in permanent first molar, five cusp in primary maxillary second molar and permanent first molar, shoveling and double shoveling with respect to permanent maxillary central incisors, four cusped primary mandibular second molar and permanent first molar, six cusped primary mandibular second molar and permanent first molar and seven cusped primary mandibular second molar and permanent first molar in 6–10 year old children belonging to the East Bengaluru, a City in India. Design: A cross-sectional survey was conducted among 2111 children by two stage sampling method. Type III examination was performed. The findings were subjected to Chi-square test. Results: 83.8% of the studied population had one or more of the variations checked for, as mentioned above. The variation most commonly seen was double shoveling (66.6%) followed by shoveling (65.7%). No significant results were observed in any trait with respect to gender. Conclusion: This study is the first of its kind, providing a baseline data of the prevalence of morphological details in the pediatric Indian population. PMID:26604571

    The study purpose was to examine parental perceptions of the mealtime environment in families with school-aged children and identify strategies to improve the dietary quality of meals. Cross-sectional surveys were completed by a convenience sample of 107 parents (86% mothers, 14% fathers) of 8- to 10-year-old children who were recruited from afterschool child care programs/elementary schools. SAS (version 9.1) was used to produce descriptive frequencies of parental reports of positive and negative perceptions of mealtime. Parents reported frequent family meals; however, they indicated that family dinners were eaten at full-service restaurants, purchased from fast-food establishments, or picked up as takeout foods at least weekly (47.0%, 28.3%, and 23.8%, respectively). Conflicts about food were problematic for some families (40.2% on at least some days), and appeared to be related to children's food pickiness. Parents reported many benefits of family meals, including time for conversation, feelings of togetherness, shared nutrition, and ceremony. Areas where parents desired change included assistance with meal planning, food preparation, and clean-up; spending more time at meals; assistance with children's food pickiness; new recipes and meal ideas; and decreasing conflict at mealtimes. Findings suggest that interventions to increase family meal frequency and promote healthful foods at mealtimes should address promoting food acceptance among children, sharing responsibilities among parents and children for meal planning and preparation, decreasing conflict at meals, and eating out healthfully.

    Tracheobronchial pediatric tumors are very rare and procedures like pneumonectomy are seldomly indicated due to the associated morbidity. If a surgical approach is considered, the ideal oncological technique would be the minimally invasive sleeve resection, allowing preservation of lung parenchyma (very important in pediatric patients). Here we present the first report of a thoracoscopic right upper tracheo-bronchial sleeve lobectomy in a pediatric patient. A 10-year-old female patient, who received multiple antibiotic treatments for recurrent pneumonia without improvement, was diagnosed with a right upper lobe (RUL) carcinoid tumor. The patient was proposed for uniportal thoracoscopic surgery. The patient was placed in a lateral decubitus position and a single 3 cm incision was performed at the anterior level of 4th intercostal space. A right upper lobectomy with a tracheo-bronchial sleeve resection using the uniportal technique was successfully performed. The postoperative course was uneventful and the patient was discharged home on the 7th postoperative day. The bronchoscopic control showed excellent caliber of the anastomosis with no complications. The uniportal video-assisted thoracoscopic surgery (VATS) approach is an excellent option for endobronchial tumor management in pediatric patients, offering a quick recovery and low morbidity. The performance of a thoracoscopic sleeve anastomosis in young patients is crucial and should only be performed by very experienced thoracoscopic surgeons. PMID:27747037

    Background. Submacular hemorrhage can occur after blunt trauma to the eye. Intravitreal tissue plasminogen activator (tPA) and gas injection are often used for treatment and are effective for submacular hemorrhage caused by age-related macular degeneration. This report describes the clinical outcome in a child with submacular hemorrhage caused by traumatic choroidal rupture who underwent successful intravitreal tPA injection and pneumatic displacement. Case Presentation. A 10-year-old boy developed sudden decrease of vision and a central scotoma in his right eye after trauma. Submacular hemorrhage was found in the eye. Visual acuity was 20/70 OD. Tissue plasminogen activator (12.5 μg in 0.05 mL) and 0.3 mL of pure sulfur hexafluoride were injected into the vitreous cavity under general anesthesia. After surgery, the patient was instructed to maintain a prone position. Displacement of the submacular hemorrhage from the fovea revealed a choroidal rupture, presumed to be the cause of the hemorrhage. After 4 months of follow-up, visual acuity was restored and final visual acuity is 20/16. Conclusion. Intravitreal tPA and gas injection can be an effective treatment for children with submacular hemorrhage. PMID:27722001

    Purpose. To examine the association of the Family Nutrition and Physical Activity (FNPA) screening tool, a behaviorally based screening tool designed to assess the obesogenic family environment and behaviors, with cardiovascular disease (CVD) risk factors in 10-year old children. Methods. One hundred nineteen children were assessed for body mass index (BMI), percent body fat (%BF), waist circumference (WC), total cholesterol, HDL-cholesterol, and resting blood pressure. A continuous CVD risk score was created using total cholesterol to HDL-cholesterol ratio (TC:HDL), mean arterial pressure (MAP), and WC. The FNPA survey was completed by parents. The associations between the FNPA score and individual CVD risk factors and the continuous CVD risk score were examined using correlation analyses. Results. Approximately 35% of the sample were overweight (19%) or obese (16%). The mean FNPA score was 24.6 +/- 2.5 (range 18 to 29). Significant correlations were found between the FNPA score and WC (r = -.35, p<.01), BMI percentile (r = -.38, p<.01), %BF (r = -.43, p<.01), and the continuous CVD risk score (r = -.22, p = .02). No significant association was found between the FNPA score and TC:HDL (r=0.10, p=0.88) or MAP (r=-0.12, p=0.20). Conclusion. Children from a high-risk, obesogenic family environment as indicated with a lower FNPA score have a higher CVD risk factor profile than children from a low-risk family environment.

    The aim of this study was to assess the reproducibility and validity of a non-quantitative 28-item food frequency questionnaire (FFQ). Children aged 9–10 years (n = 50) from three schools in Dunedin, New Zealand, completed the FFQ twice and a four-day estimated food diary (4DEFD) over a two-week period. Intraclass correlation coefficients (ICC) and Spearman’s correlation coefficients (SCC) were used to determine reproducibility and validity of the FFQ, respectively. Weekly intakes were estimated for each food item and aggregated into 23 food items/groups. More than half of the food items/groups (52.2%) had an ICC ≥0.5. The median SCC between FFQ administrations was 0.66 (ranging from 0.40 for processed meat to 0.82 for sweets and non-dairy drinks). Cross-classification analysis between the first FFQ and 4DEFD for ranking participants into thirds showed that breakfast cereals had the highest agreement (54.0%) and pasta the lowest (34.0%). In validity analyses, 70% of food items/groups had a SCC ≥0.3. Results indicate that the FFQ is a useful tool for ranking children according to food items/groups intake. The low respondent burden and relative simplicity of the FFQ makes it suitable for use in large cohort studies of 9–10 year-old children in New Zealand. PMID:27164137

    Limbic encephalitis is a rare neurological disorder that may be difficult to recognize. Clinical features include memory impairment, temporal lobe seizures and affective disturbance. We report the case of a 10-year-old girl with type 1 diabetes mellitus that presented with seizures, depressed mood and memory changes. The diagnosis of glutamic acid decarboxylase 65 (GAD65) mediated limbic encephalitis relied on cerebral magnetic resonance imaging lesions and high serological and cerebrospinal fluid GAD65-antibodies titers. High-dose steroidal therapy was started with clinical improvement. Relapse led to a second high-dose steroid treatment followed by rituximab with remission. A correlation between serum GAD65-antibodies levels and symptoms was found, demonstrating GAD65-antibodies titers may be useful for clinical follow-up and immunotherapy guidance. This report raises awareness of this serious neurological condition that may be associated with type 1 diabetes, underlining the importance of an early diagnosis and prompt treatment for a better prognosis.

    Traffic injuries have become a major health-related issue to school-aged children. To study this type of injury with numerical simulations, a finite element model was developed to represent the full body of a 10-year-old (YO) child. The model has been validated against test data at both body-part and full-body levels in previous studies. Representing only the average 10-YO child, this model did not include subject-specific attributes, such as the variations in size and shape among different children. In this paper, a new modeling approach was used to morph this baseline model to a subject-specific model, based on anthropometric data collected from pediatric subjects. This mesh-morphing method was then used to rapidly morph the baseline mesh into the subject-specific geometry while maintaining a good mesh quality. The morphed model was subsequently applied to simulate a real-world motor vehicle crash accident. A lung injury observed in the accident was well captured by the subject-specific model. The findings of this study demonstrate the feasibility of the proposed morphing approach to develop subject-specific human models, and confirm their capability in prediction of traffic injuries.

    Heart rate variability (HRV) is a non-invasive quantitative marker of cardiac autonomic function derived from continuous electrocardiogram (ECG) recordings. Normative HRV values and development factors have not been established in pediatric populations. The objective was to derive referent time- and frequency-domain HRV values for a population-based sample of children. Children aged 9-11 years (N = 1,036) participated in the Québec Longitudinal Study of Child Development cohort cardiovascular health screening. Registered nurses measured anthropometrics (height, weight) and children wore an ambulatory Holter monitor to continuously record an ECG signal. HRV variables included time (SDNN, pNN50, RMSSD, SDANN) and frequency (HF, LF, LF/HF ratio) domain variables. Normative HRV values, stratified by age, sex, and heart rate, are presented. Greater heart rate (β avg  = -0.60, R avg (2)  = 0.39), pubertal maturation (β avg = -0.11, R avg (2)  = 0.01), later ECG recording times (β avg = -0.19, R avg (2)  = 0.07), and higher diastolic blood pressure (β avg = -0.11, R avg (2)  = 0.01) were significantly associated with reduced HRV in 10-year-old children. The normative HRV values permit clinicians to monitor, describe, and establish pediatric nosologies in primary care and research settings, which may improve treatment of diseases associated with HRV in children. By better understanding existing values, the practical applicability of HRV among clinicians will be enhanced. Lastly, developmental (e.g., puberty) and procedural (e.g., recording time) factors were identified that will improve recording procedures and interpretation of results. PMID:25056158

    The objective of this work was to study through in the electromyography the upper and lower umbilical rectus abdominis and the anterior and posterior parts of the external oblique muscles of children 8 to 10 years old. The children studied practice artistic and rhythmical gymnastic sports at the training and learning level and the study was made during abdominal exercise in the dorsal decubitus position on the ground and on a board. The children were divided into 2 groups: Group I - ten already trained children; Group II - nineteen learners. The participants in Group I practiced an average of 5 times a week and those in Group II practiced 2 times a week. The exercises analyzed were: on the ground, lifting the legs 30, 20 and 10 cm high with the knees flexed 90 degrees; flexing the trunk while maintaining the legs elevated and the knees flexed; flexing the trunk with homo and heterolateral rotation of the trunk while maintaining the legs elevated and the knees flexed. On the board, flexing the trunk with the knees flexed 90 degrees on top of the board inclined 30, 20 and 10 cm; flexing the trunk with rotation of the trunk homo and heterolateral with the knees flexed on the board inclined 30, 20 and 10 cm. The results showed that the superior umbilical part of the rectus abdominis muscle presented more intense action potential than the inferior-umbilical part; the more intense action potential occurred at the flexing of the trunk and at the flexing of the trunk with homo and heterolateral rotation. The anterior part of the external oblique muscle presented more intense action potential than the posterior part; the more intense action potential occurred at the flexing of the trunk and at the flexing of the trunk with heterolateral rotation. In both of the muscles the more intense action potential occurred between 45 and 60 degrees of flexing the trunk; the children in Group I presented more intense action potential than those in Group II; the exercise of lifting the

    Background Little is known about ethnic, cultural and socioeconomic differences in childhood ownership and attitudes to pets. The objective of this study was to describe the factors associated with living with different pet types, as well as factors that may influence the intensity of relationship or ‘attachment’ that children have to their pet. Data were collected using a survey of 1021 9–10 year old primary school children in a deprived area of the city of Liverpool, UK. Results Dogs were the most common pet owned, most common ‘favourite’ pet, and species most attached to. Twenty-seven percent of dog-owning children (10% of all children surveyed) reported living with a ‘Bull Breed’ dog (which includes Pit Bulls and Staffordshire Bull Terriers), and the most popular dog breed owned was the Staffordshire Bull Terrier. Multivariable regression modelling identified a number of variables associated with ownership of different pets and the strength of attachment to the child’s favourite pet. Girls were more likely to own most pet types, but were no more or less attached to their favourite pet than boys. Children of white ethnicity were more likely to own dogs, rodents and ‘other’ pets but were no more or less attached to their pets than children of non-white ethnicity. Single and youngest children were no more or less likely to own pets than those with younger brothers and sisters, but they showed greater attachment to their pets. Children that owned dogs lived in more deprived areas than those without dogs, and deprivation increased with number of dogs owned. ‘Pit Bull or cross’ and ‘Bull Breed’ dogs were more likely to be found in more deprived areas than other dog types. Non-whites were also more likely to report owning a ‘Pit Bull or cross’ than Whites. Conclusions Gender, ethnicity and socioeconomic status were associated with pet ownership, and sibling status with level of attachment to the pet. These are important to consider when

    Basic competence in theory of mind is acquired during early childhood. Nonetheless, evidence suggests that the ability to take others' perspectives in communication improves continuously from middle childhood to the late teenage years. This indicates that theory of mind performance undergoes protracted developmental changes after the acquisition of basic competence. Currently, little is known about the factors that constrain children's performance or that contribute to age-related improvement. A sample of 39 8-year-olds and 56 10-year-olds were tested on a communication task in which a speaker's limited perspective needed to be taken into account and the complexity of the speaker's utterance varied. Our findings showed that 10-year-olds were generally less egocentric than 8-year-olds. Children of both ages committed more egocentric errors when a speaker uttered complex sentences compared with simple sentences. Both 8- and 10-year-olds were affected by the demand to integrate complex sentences with the speaker's limited perspective and to a similar degree. These results suggest that long after children's development of simple visual perspective-taking, their use of this ability to assist communication is substantially constrained by the complexity of the language involved.

    Are individual differences in numerical performance sustained by variations in gray matter volume in schoolchildren? To our knowledge, this challenging question for neuroeducation has not yet been investigated in typical development. We used the Voxel-Based Morphometry method to search for possible structural brain differences between two groups of 10-year-old schoolchildren (N = 22) whose performance differed only in numerical transcoding between analog and symbolic systems. The results indicated that children with low numerical proficiency have less gray matter volume in the parietal (particularly in the left intraparietal sulcus and the bilateral angular gyri) and occipito-temporal areas. All the identified regions have previously been shown to be functionally involved in transcoding between analog and symbolic numerical systems. Our data contribute to a better understanding of the intertwined relationships between mathematics learning and brain structure in healthy schoolchildren. PMID:23630510

    Background: Aneurysmal bone cysts are rare occurrences in the cervical spine. Surgical treatment in pediatric patients is a challenge. Complete tumor resection offers the best chance for cure. Description: Diagnosis and surgical management of an expansile aneurysmal bone cyst of the cervical spine involving all three spinal columns in a 10-year-old boy. Results: Surgical treatment included tumor excision and circumferential fusion, and produced no neurological or vascular sequelae. This approach minimizes the risk of recurrence and the possibility of postoperative spinal instability. Conclusion: Spinal instability is preferably addressed with reconstruction and stabilization. Cervical aneurismal bone cyst lesions are ideally treated with complete resection to minimize the chance of recurrence. In pediatric cases, defects created by resection should be corrected by fusion to minimize the risk of postoperative instability and growth abnormality. PMID:23526912

The first group included 15 children with local EEG deviations in the right hemisphere, and the second group included 21 children without EEG deviations from the age norm (control group). In both groups, verbal and nonverbal higher mental functions and the ability to voluntary control of activity were assessed by means of neuropsychological methods. As compared to children of the control group, children with local EEG deviations in the right hemisphere demonstrated some difficulties in strategy formation, reduced ability to maintain already formed programs, increased fatigue, changes in affective behavior (anxiety and behavioral excitability), deficit of visual and somatosensory perceptual synthesis, reduction in object recognition efficiency, and visual memory deficit.

    Introduction Provision of oral health knowledge to the children by their teachers at the school level can prove to be more fruitful because it is the time period during which the children begin to learn the basic oral hygiene practices and are most prone to dental caries. Aim This study was carried out to assess the effect of training school teachers on oral hygiene status of 8-10 years old government school children of Udaipur city, India. Materials and Methods A total of nine school teachers and 279, 8-10 year old school children from two government schools were included in the study. The questionnaire on oral health knowledge and practice contained 17 questions to evaluate the knowledge and practice of children towards oral hygiene before and after the teachers training program. Baseline and six months post training data on oral health knowledge and practice was obtained by the questionnaire method. Baseline and six months post training data on oral hygiene status was obtained by OHI-S Index. Statistical analysis was done using software SPSS 22, the test used were McNemar’s test, paired t-test. Results Pre and post training data were compared and it was found that there was a significant improvement in oral health knowledge and practices of school teachers and children. Also oral hygiene status of school children was significantly improved after the program. Conclusion Results of the present study suggest that experiential learning is an effective school based oral health education method for improvement of oral hygiene in primary school children.

    A 10-year old MueTec2010, white light CD measurement system, installed at DNP Photomask Europe and previously owned by STMicroelectronics, has been upgraded to fulfill the high-end optical CD measurement requirements, and to add the film thickness measurement capability. That is the ultimate upgrade, consisting of two new computers with WINDOWS 2000 operating system, a new 150X measurement objective, a new 16-bit CCD digital camera, a new tube lens for the old Leica Ergoplan microscope, and the NanoStar software with the pattern recognition option. The upgrade yielded an average 45% repeatability improvement for isolated and dense lines and spaces, with 1.2nm average repeatability in a 0.3-10μm CD nominal range. Contact holes report an average 50% repeatability improvement, with 2.5nm average repeatability. The improved precision allows a +/-2-nm CD calibration and correlation down to 0.4μm CD nominal. Overall, the upgraded MueTec2010 shows same or better performance than the already installed Leica LWM250UV CD measurement system, despite the longer illumination wavelength of the former. The improved short and long term repeatability reduced the Gauge RandR figure from 24% to 11% at +/-20nm tolerance, which qualifies the system for high-end binary mask down to 0.5μm CD nominal. The feasibility to calibrate the system for 248nm Molybdenum Silicide Phase Shifting Masks is currently being investigated. In addition to that, the new measurement algorithms, the capability to take multiple measurements within the FOV, and the pattern recognition capability included in the NanoStar software gave a 75% throughput boost to the fully automated macros for the weekly calibration tests of the laser writing tools, compared to the LWM250UV run time. With little additional hardware and software, the system has also been upgraded to include the film thickness measurement capability for the PSM resist coating process (2nd exposure), without the need for a dedicated, more expensive

    The purpose of this study was to develop new conceptual designs for large Pb, Fe, and U-shielded spent fuel casks which have been optimized for the shipment of 2-, 3-, 5-, 7-, or 10-year-old PWR spent fuel assemblies. Design specifications for about 100 cases of potential interest are presented along with a brief 20-page synopsis of the associated analyses. Optimized shielding requirements are presented for each type of cask as a function of the age of the spent fuel and the number of assemblies in the cask. With respect to criticality, a new type of inherently subcritical fuel assembly separator is described which uses hollow, borated stainless-steel tubes in the wall-forming structure between the assemblies. Steady-state and transient heat transfer analyses for casks under nominal and accident conditions were performed using the SCOPE code for Shipping Cask Optimization and Parametric Evaluation. Based on criticality, shielding, and heat transfer considerations, it appears that optimized cask designs could be developed to carry 15 to 18 five-year-old PWR fuel assemblies or as many as 18 to 21 ten-year-old PWR fuel assemblies. 4 figures, 4 tables.

    The current study investigated the development of metacognitive monitoring-based control of spacing choices in children and adults. Moreover, we assessed whether metacognitive learning decisions are influenced by the effects of previous metacognitive decisions. We tested groups of 7-year-olds, 10-year-olds, and adults in a task with two learning blocks in which they needed to monitor their learning through judgments of learning (JoL) and in which they then needed to decide whether to space their study, mass it, or terminate it. Extending previous findings, our study provides the first evidence that already by 7 years of age children can make metacognitive controlled scheduling decisions. The results also revealed that adults had more clearly differentiated strategies related to their JoL. Furthermore, our study provides evidence that participants of all age groups improved their relative monitoring accuracy in the second learning block and adjusted their JoL. However, only adults changed their strategy choices. PMID:25703006

    Objectives: The premature loss of primary teeth is a potential risk factor for poor arch length development. Adequate arch length is important to the progression of the permanent teeth. Poor arch length can lead to crowding, ectopic eruption, or impaction of these teeth. This study is designed to assess the prevalence of premature loss of primary teeth in the 5-10-year-old age group. Materials and Methods: The study group included 185 children, that is, 91 boys and 94 girls. The dental examination was conducted by an experienced examiner under sufficient artificial light. Data including patient age and missing teeth were collected. Descriptive statistics were applied for data analysis, and from the results, Chi-square tests were used at a level of significance of 5% (P < 0.05). Results: We observed a 40.54% prevalence of premature loss of primary teeth with no statistically significant difference between genders. The lower left primary second molar was the most commonly absent tooth in the dental arch (13.5%). Conclusion: The status of premature loss of primary teeth was high in the study group. Implementation of efficient educational and preventive programs to promote oral health would help children maintain a healthy primary dentition and eventually prevent the disturbances in the future development of normal occlusion. Early detection and management of the space problems associated with the early loss of primary teeth would help in reducing malocclusion problems.

    Pediatric primary care is an important setting in which to address obesity prevention, yet relatively few interventions have been evaluated and even fewer have been shown to be effective. The development and evaluation of cost-effective approaches to obesity prevention that leverage opportunities of direct access to families in the pediatric primary care setting, overcome barriers to implementation in busy practice settings, and facilitate sustained involvement of parents is an important public health priority. The goal of the Healthy Homes/Healthy Kids (HHHK 5-10) randomized controlled trial is to evaluate the efficacy of a relatively low-cost primary care-based obesity prevention intervention aimed at 5 to 10 year old children who are at risk for obesity. Four hundred twenty one parent/child dyads were recruited and randomized to either the obesity prevention arm or a contact control condition that focuses on safety and injury prevention. The HHHK 5-10 obesity prevention intervention combines brief counseling with a pediatric primary care provider during routine well-child visits and follow-up telephone coaching that supports parents in making home environmental changes to support healthful eating, activity patterns, and body weight. The contact control condition combines the same provider counseling with telephone coaching focused on safety and injury prevention messages. This manuscript describes the study design and baseline characteristics of participants enrolled in the HHHK 5-10 trial. PMID:23816490

    This report details many of the interrelated considerations involved in optimizing large Pb, Fe, or U-metal spent fuel shipping casks containing 1, 2, 3, 5, 7, or 10-year-old PWR fuel assemblies. Scoping analyses based on criticality, shielding, and heat transfer considerations indicate that some casks may be able to hold as many as 18 to 21 ten-year-old PWR fuel assemblies. In the criticality section, a new type of inherently subcritical fuel assembly separator is described which uses hollow, borated stainless-steel tubes in the wall-forming structure between the assemblies. In another section, details of many n/..gamma.. shielding optimization studies are presented, including the optimal n/..gamma.. design points and the actual shielding requirements for each type of cask as a function of the age of the spent fuel and the number of assemblies in the cask. Multigroup source terms based on ORIGEN2 calculations at these and other decay times are also included. Lastly, the numerical methods and experimental correlations used in the steady-state and transient heat transfer analyses are fully documented, as are pertinent aspects of the SCOPE code for Shipping Cask Optimization and Parametric Evaluation. (While only casks for square, intact PWR fuel assemblies were considered in this study, the SCOPE code may also be used to design and analyze casks containing canistered spent fuel or other waste material. An abbreviated input data guide is included as an appendix).

    Most studies do not consider the potential variation in carbon concentration among the different tree components of the same species in regional scale. This study examined the carbon concentrations of the components (i.e., foliage, branch, stem, and root) in a 10-year-old poplar species (Populus davidiana Dode) from the Desertification Combating Program of Northern China. The highest and lowest carbon concentrations were found in the stem and foliage, respectively. There was a significant difference in carbon concentrations among the different tree components. All of the observed carbon concentrations of tree components were lower than those predicted using the conversion factor of 0.5 applied to component biomass. Stem carbon made up 59.7% of the total tree biomass carbon. The power equation estimating proportion of tree biomass carbon against the independent variable of diameter at breast height explained more than 90% of the variability in allocation of carbon among tree components. Tree height, as a second independent variable is also discussed. Our results suggest that the difference in organic carbon concentration among tree components should be incorporated into accurately develop forest carbon budget. Moreover, further investigations on how the diameter at breast height equation developed in the present study performs across broader scales are required.

  4. Is waist-to-height ratio a useful indicator of cardio-metabolic risk in 6-10-year-old children?

    PubMed Central

    2013-01-01

    Background Childhood obesity is a public health problem worldwide. Visceral obesity, particularly associated with cardio-metabolic risk, has been assessed by body mass index (BMI) and waist circumference, but both methods use sex-and age-specific percentile tables and are influenced by sexual maturity. Waist-to-height ratio (WHtR) is easier to obtain, does not involve tables and can be used to diagnose visceral obesity, even in normal-weight individuals. This study aims to compare the WHtR to the 2007 World Health Organization (WHO) reference for BMI in screening for the presence of cardio-metabolic and inflammatory risk factors in 6–10-year-old children. Methods A cross-sectional study was undertaken with 175 subjects selected from the Reference Center for the Treatment of Children and Adolescents in Campos, Rio de Janeiro, Brazil. The subjects were classified according to the 2007 WHO standard as normal-weight (BMI z score > −1 and < 1) or overweight/obese (BMI z score ≥ 1). Systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting glycemia, low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglyceride (TG), Homeostatic Model Assessment – Insulin Resistance (HOMA-IR), leukocyte count and ultrasensitive C-reactive protein (CRP) were also analyzed. Results There were significant correlations between WHtR and BMI z score (r = 0.88, p < 0.0001), SBP (r = 0.51, p < 0.0001), DBP (r = 0.49, p < 0.0001), LDL (r = 0.25, p < 0.0008, HDL (r = −0.28, p < 0.0002), TG (r = 0.26, p < 0.0006), HOMA-IR (r = 0.83, p < 0.0001) and CRP (r = 0.51, p < 0.0001). WHtR and BMI areas under the curve were similar for all the cardio-metabolic parameters. A WHtR cut-off value of > 0.47 was sensitive for screening insulin resistance and any one of the cardio-metabolic parameters. Conclusions The WHtR was as sensitive as the 2007 WHO BMI in screening for metabolic risk factors in 6-10-year-old children. The public health message “keep your waist to less

    The authors present a case of echocardiographic diagnosis of a rare congenital cardiovascular anomaly in the form of mixed partial anomalous pulmonary veins connection in a 10-year-old girl with Turner syndrome and congenital mild stenosis of insufficient bicuspid aortic valve, made while diagnosing the causes of intestinal tract bleeding. The article presents various diagnostic difficulties leading to the delayed determination of a correct diagnosis, resulting from the absence of symptoms of circulatory failure in the early stage of the disease and the occurrence of severe and dominant auscultatory phenomena typical for congenital aortic valve defect which effectively masked the syndromes of increased pulmonary flow. The authors discuss the role of the impact of phenotypic characteristics of the Turner syndrome, in particular a short webbed neck restricting the suprasternal echocardiographic access and the presence of psychological factors associated with a long-term illness. The importance of indirect echocardiographic symptoms suggesting partial anomalous pulmonary veins connection in the presence of bicuspid aortic valve, e.g. enlargement of the right atrium and right ventricle, and paradoxical interventricular septum motion were emphasized in patients lacking ASD, pulmonary hypertension or tricupid and pulmonary valve abnormalities. The methodology of echocardiographic examination enabling direct visualization of the abnormal vascular structures was presented. Special attention was paid to the significance of highly sensitive echocardiographic projections: high right and left parasternal views in sagittal and transverse planes with patient lying on the side, with the use of two-dimensional imaging and color Doppler. Finally, the limitations of echocardiography resulting from the visualization and tracking of abnormal vascular structures hidden behind ultrasound non-conductive tissues were indicated, as was the role of other diagnostic modalities, such as angio

    Skin piercings continues to be a growing socially accepted phenomenon. The nursing profession needs to modify and increase its knowledge in order to adequately respond to this new situation. The nursing profession must learn what are the legal parameters which regulate skin piercing, what type of health education should be applied regarding skin piercing, what limits exist when carrying out skin piercing on patients, what prior- and post-piercing treatments are required, as well as the possible complications which may occur due to skin piercing and how to deal with those complications once they arise.

    Differentiation between the normal variant cleft epiphysis and Salter-Harris type III fracture of the first proximal phalanges of the foot in children might be challenging. The authors describe a case of a 10-year-old ballet dancer girl with bilateral epiphyseal segmentation of the first proximal phalanges of the foot, unresponsive to conservative treatment. Considered a nonhealing stress-induced fracture, operative treatment with closed reduction and Herbert screw insertion was chosen on both sides. Complete union was achieved, with significant reduction of pain. The presented case suggests that internal fixation can be a viable option in the treatment of the problem. PMID:26919623

    Background. The oral an perioral piercing has a long history as part of religious, tribal,cultural or sexual symbolism and nowdays there is a high incidence of oral and perioral piercing in the adolescent population. This practice has a long history as part of religious, tribal, cultural or sexual symbolism. This article reviews current knowledge on injuries or diseases that might be produced by piercing in the oral cavity. We propose a classification to diagnosed the pathologies related to oral an perioral piercing Methods. A search was conducted of articles in PubMed, Scielo published between 1997 and 2007, using the key words ``oral and perioral, piercing ´´, ``oral, piercing and disease”, ``recessions and oral piercing´´. It has reviewed about twentythree articles 17 were narrative reviews and 6 case series Results. A review was carried out on the origins of oral and perioral body piercing and its local implications, classifying the different alterations like recessions, systemic implications that it can produce in the oral and perioral cavity. Conclusion. Patients with oral and perioral piercing should be regularly followed up because of the possible development of different types of adverse effects. Clinical implications. Adverse effects of oral and perioral piercing can be systemic, with transmission of infectious diseases such as hepatitis B or C, or can be local, with alteration of oral mucosae or even of dental structures.

    OBJECTIVE The objective of this study was to assess attitudes of patrons and medical school faculty about physicians with nontraditional facial piercings. We also examined whether a piercing affected the perceived competency and trustworthiness of physicians. DESIGN Survey. SETTING Teaching hospital in the southeastern United States. PARTICIPANTS Emergency department patrons and medical school faculty physicians. INTERVENTIONS First, patrons were shown photographs of models with a nontraditional piercing and asked about the appropriateness for a physician or medical student. In the second phase, patrons blinded to the purpose of the study were shown identical photographs of physician models with or without piercings and asked about competency and trustworthiness. The third phase was an assessment of attitudes of faculty regarding piercings. MEASUREMENTS AND MAIN RESULTS Nose and lip piercings were felt to be appropriate for a physician by 24% and 22% of patrons, respectively. Perceived competency and trustworthiness of models with these types of piercings were also negatively affected. An earring in a male was felt to be appropriate by 35% of patrons, but an earring on male models did not negatively affect perceived competency or trustworthiness. Nose and eyebrow piercings were felt to be appropriate by only 7% and 5% of faculty physicians and working with a physician or student with a nose or eyebrow piercing would bother 58% and 59% of faculty, respectively. An ear piercing in a male was felt to be appropriate by 20% of faculty, and 25% stated it would bother them to work with a male physician or student with an ear piercing. CONCLUSIONS Many patrons and physicians feel that some types of nontraditional piercings are inappropriate attire for physicians, and some piercings negatively affect perceived competency and trustworthiness. Health care providers should understand that attire may affect a patient's opinion about their abilities and possibly erode confidence

    Sjogren-Larsson syndrome (SLS) is an autoimmune disease, uncommon in childhood. We report a case of SLS in a 10-year-old girl with a history of tumor, calor and rubor in the back of her toes almost every month, which resolved in 4-5 days without therapy. She did not complain of dry mouth or dry eyes. The laboratory findings showed high inflammation markers, rheumatoid factor 128 IU, Waaler-Rose 256 IU, anti nuclear antibody (ANA) 1/640, SSA (anti Sjogren antigen A) and SSB (anti Sjogren antigen B) positive and hypergammaglobulinemia. The Schirmer's test resulted to be pathologic, the ultrasonography images and biopsy of minor salivary glands revealed focal periductal lymphocytic infiltrate and sialoduct ectasia class IV of juvenile Sjogren syndrome. The juvenile Sjogren syndrome is frequently under-diagnosed. Clinical manifestations in children might be different from the adult form, although laboratory findings may be similar to those found in adults.

    In Europe, the piercing mode has naturally been associated with specific complications raising an important public health problem. The debate on the role physicians should play requires a careful analysis of the ethical issues involved. Specifically, should the piercing be done in a medical setting? This question is raised because, when performed under ideal conditions, the act of piercing requires a certain degree of medical competency: history taking, asepsia, technical procedure (hemostasis), anesthesia.... However, mandatory medicalization would not, in our opinion, appear to be desirable since we are dealing with a social rite which lies outside the domain of specific medical care. Nevertheless, although we do not advocate systematic medicalization, we do believe that medicine should play a role, in terms of public health, in this emerging practice. We discuss the modalities of a health education dialogue which could be established with professional practicing piercing.

    Recently, gain-of-function (GOF) mutations in the gene encoding signal transducer and activator of transcription 1 (STAT1) have been associated with chronic mucocutaneous candidiasis (CMC). This case report describes a 10-year-old boy presenting with signs of common variable immunodeficiency (CVID), failure to thrive, impaired neurological development, and a history of recurrent mucocutaneous Candida infections. Sequencing of the STAT1 gene identified a heterozygous missense mutation in exon 7 encoding the STAT1 coiled-coil domain (c.514T>C, p.Phe172Leu). In addition to hypogammaglobulinemia with B-cell deficiency, and a low percentage of Th17 cells, immunological analysis of the patient revealed a marked depletion of forkhead-box P3(+)-expressing regulatory T cells (Tregs). In vitro stimulation of T cells from the patient with interferon-α (IFNα) and/or IFNɣ resulted in a significantly increased expression of STAT1-regulated target genes such as MIG1, IRF1, MX1, MCP1/CCL2, IFI-56K, and CXCL10 as compared to IFN-treated cells from a healthy control, while no IFNα/ɣ-mediated up-regulation of the FOXP3 gene was found. These data demonstrate that the STAT1 GOF mutation F172L, which results in impaired stability of the antiparallel STAT1 dimer conformation, is associated with inhibited Treg cell development and neurological symptoms.

    It is important to understand adult outcomes in childhood obesity prevention programs as parents and caregivers have a significant influence on the eating and physical activity habits of youth. Grounded in the social cognitive theory, the iCook 4-H study was centered on a dyad model (9-10 year-olds and their primary meal preparers) to teach healthy cooking skills, shopping and meal habits, and being active as a family. The program took place in five states and dyads (n = 54) were recruited through flyers, e-mails, and in-person contact. The focus of this article is to provide findings from adult program participants. Demographics and self-reported food intake, procurement, preparation and safety practices, feeding relationships, mealtime routines, and height and weight were collected through surveys at baseline and program completion, which spanned 3 months. Descriptive statistics including two-related samples tests and paired samples t tests were used to assess pre- and post-program survey data responses at p < 0.05 significance level. Most had a bachelor's degree (31%) or some college (29%), about half were white, 66% were married, about 30% of households participated in assistance programs, and 82% were female. At program conclusion, participants significantly improved meal planning, prioritizing healthy meal choices, shopping with a grocery list, and reading Nutrition Facts Labels. There were also significant, positive differences noted in cooking skill confidence (p = 0.015), desire to cook more meals at home, and fewer fast food meals. Adult-youth feeding interactions also significantly improved. There were also significant increases in fruit juice (100%), vegetable soup, and whole grain consumption. Based on results, adults reported improvements in meal planning, cooking, and purchasing skills that were taught in classes. PMID:26970294

    2010-01-01

    Tongue piercing has become an increasingly popular form of body art. However, this procedure can occasionally be complicated by serious bacterial infections. The present article reports a case of prosthetic valve endocarditis caused by a Gemella species in a patient with a pierced tongue, and reviews 18 additional cases of local and systemic bacterial infections associated with tongue piercing. Infections localized to the oral cavity and head and neck region included molar abscess, glossal abscess, glossitis, submandibular lymphadenitis, submandibular sialadenitis, Ludwig’s angina and cephalic tetanus. Infections distal to the piercing site included eight cases of infective endocarditis, one case of chorioamnionitis and one case of cerebellar abscess. Oropharyngeal flora were isolated from all cases. While bacterial infections following tongue piercing are rare, there are reports of potentially life-threatening infections associated with the procedure. Both piercers and their clients should be aware of these potential complications, and standardized infection prevention and control practices should be adopted by piercers to reduce the risk.

    Body piercing, a type of body modification that is practiced in many cultures, creates an unnatural tract through tissue that is then held open by artificial means. Today, professional body piercing is often performed in piercing establishments that are subject to dissimilar forms of regulation. The most frequently reported medical complication of body piercing and similar body modifications, such as dermal implantation, is infection. Patients with piercings who undergo surgery may have additional risks for infection, electrical burns, trauma, or airway obstruction. The published research literature on piercing prevalence, complications, regulations, education, and nursing care is outdated. The purpose of this article is to educate nurses on topics related to nursing care for patients with piercings and similar body modifications, including the history, prevalence, motivations for, and perceptions of body piercings as well as possible complications, devices used, locations, healing times, regulations, patient education, and other health concerns.

    The associations of body piercing with other social characteristics, personality, and sexual behavior were investigated in a population-based sample of young adults, in light of the theory that body piercing has meaning in terms of a corporeal expression of the self. At age 26 years, 966 (95%) of 1019 members of the birth-cohort of the Dunedin Multidisciplinary Health and Development Study were asked about body piercing (at interview) and sexual behavior (questions presented by computer). Assessment of personality traits was conducted at ages 18 or 21 years. In total, 183 participants (9% of the men and 29% of the women) had piercings at a site other than the earlobes. People who lived outside New Zealand or who were of Maori descent were more likely to be pierced, but unemployment and low occupational status were not significantly related to piercing. Women who were pierced, compared with those without piercings, were more likely to have personality traits of low constraint or high negative emotionality. Women with piercings were also more likely to report having had, during the previous year, five or more heterosexual partners (odds ratio, 5.8, 95% CI: 2.3-14.6) or any same-sex partner involving genital contact (odds ratio, 10.3, CI: 2.9-37.2). The associations with sexual behavior in men were weaker and not statistically significant. In this population, body piercing in women was associated with sexual behavior. Having multiple heterosexual partners or any same-sex partner was very rare among women without piercings. The theory of meaning for body piercing was generally supported, offering the possibility of a richer understanding of this phenomenon in the general population.

    The implication of a traumatic injury to a permanent molar tooth as a complication by tongue piercing with ornamental jewelry is reported. An appropriate restorative management of the fractured tooth is described. The dentist's role in prevention and treatment of unfavorable complications is outlined. The rationales for selection of specific treatment modalities, in view of the degree of damage to hard dental tissues, are discussed. The range of hard tissue injuries resulting from tongue jewelry varies from a simple crack propagating into the enamel to a fractured tooth. A variety of factors must be considered before employing the available restorative methods. PMID:11491628

    The new legal regulations and agreements dealing with the type of locales and personnel authorized to implant body rings through pierced holes known popularly as piercings brings with it the need for nurses to learn about this practice and to adapt our habitual sanitary techniques, in an urgent manner, in order to cover the increasing aesthetic demand. The nursing profession needs to amplify its range of treatments for this piercing practice so it is not limited to merely inserting rings or studs in holes.

    2009-10-01

    Piercings and tattoos have become very popular in western society in recent decades, particularly among younger generations. Reports of medical complications associated with these decorative techniques have increased in parallel with the rise in their popularity. Due to their high frequency, adverse cutaneous reactions are particularly important among these potential complications. Tattoo-related complications include a number of cutaneous and systemic infections secondary to breach of the epidermal barrier, acute and delayed inflammatory reactions with different histopathological patterns, the appearance of benign and malignant tumors on tattooed areas of skin, and certain dermatoses triggered by isomorphic phenomena. Piercing-related complications are similar, though some, such as pyogenic skin infections, are much more common due to the delayed wound healing after piercing in certain sites. We must differentiate between complications that are independent of the site of piercing, and specific complications, which are closely related to the body area pierced. The rate of complications after performing piercings or tattoos depends on the experience of the artist, the hygiene techniques applied, and the postprocedural care by the customer. However, some of these complications are unpredictable and depend on factors intrinsic to the patient. In this article, we review the most common decorative techniques of body art, with particular focus on the potential cutaneous complications and their management. PMID:19775542

    Primary bone lymphoma has been defined as a solitary lesion in bone, without concomitant involvement of the extra osseous hematopoietic system, with no evidence of extra osseous disease within 6 months of the onset of symptoms. The vast majority of cases are of the large B-cell non-Hodgkin type. They are rare bone tumor. Distinguishing primary bone lymphoma from other bone tumors is important because the former has a better response to therapy and a better prognosis. PMID:24617185

    : This study reports on the QEEG observations recorded from a yogi during tongue piercing in which he demonstrated voluntary pain control. The QEEG was recorded with a Lexicor 1620 from 19 sites with appropriate controls for impedence and artifacts. A neurologist read the data for abnormalities and the QEEG was analyzed by mapping, single and multiple hertz bins, coherence, and statistical comparisons with a normative database. The session included a meditation baseline and tongue piercing. During the meditative baseline period the yogi's QEEG maps suggesting that he was able to lower his brain activity to a resting state. This state showed a predominance of slow wave potentials (delta) during piercing and suggested that the yogi induced a state that may be similar to those found when individuals are under analgesia. Further research should be conducted with a group of individuals who demonstrate exceptional self-regulation to determine the underlying mechanisms, and whether the skills can be used to teach others how to manage pain.

    A. Keith Pierce was a solar astronomer who will be remembered for bringing the physics lab to the telescope and for his design of the world's largest solar telescope, the 1.5-meter McMath Telescope on Kitt Peak in Arizona. Born in Lincoln, Nebraska, he died of cancer in Tucson on 11 March 2005. He was eighty-six. His father, Tracy Pierce, had gone to graduate school in Berkeley, California, with a major in mathematics and a minor in astronomy. Fellow students of his class included Seth Nicholson and Donald Shane, people who were later to influence young Keith's life. Tracy Pierce received an appointment as an instructor, later Professor, of mathematics at the University of Nebraska in Lincoln. In his spare time dad Tracy became something of a telescope nut, following "the bible" —Albert Ingall's A.T.M (Amateur Telescope Making). His enthusiasm rubbed off on his son. Seth Nicholson, who became a famous Mt. Wilson Observatory astronomer, and Donald Shane from Berkeley, both stayed at the Pierce home while on their Sigma Xi lecture tours. After two years at Lincoln, followed by two more at Berkeley, Keith had earned his bachelor's degree in astronomy. During World War II, Dr. Shane became personnel director at the E.O. Lawrence Radiation Lab and arranged for Keith to work there at the cyclotron. A crash program to produce U235 from U238 was under way. At a crucial point in 1942 the cyclotron turned out the sought-after material. Much celebration ensued among the Rad Lab leaders. During this gala, Keith was on the night-shift and pretty much on his own. It was then that he turned a valve to the right, when left was called for, and the entire system went down. Shortly thereafter he was sent to Oak Ridge for the duration of the war. He cannot have been thought of badly, however, because he was invited to the Trinity test in New Mexico. (He didn't go because of the pending birth of his first son, John.) The year 1945 found Keith back in Berkeley working on his Ph

    Body piercing indicates the puncturing of a part of the body in which jewelry may be worn. In recent years, oral piercing is increasingly popular especially among young people. Body piercing has to be considered as a surgical procedure to all intents and purposes and, as such, has to be performed only by qualified personnel able to assure high standards of professionalism in facilities subject to sanitary inspections. The aim of the present work is to verify what risks patients may be exposed to and what complications may occur after a healthcare professional performs oral piercing. Our retrospective study includes 108 patients (74 males and 34 females) aged between 14 and 39 years, who had oral piercing done 12±4 months earlier. All the patients underwent clinical examination to reveal the possible presence of late complications. After piercing, none of the 108 patients developed widespread complications. Although all patients said they had followed the piercers' instructions, 96% of them reported postoperative local complications such as bleeding within 12 hours of piercing (90%), perilesional edema for 3±2 days after piercing surgery (80%), and persistent mucosal atrophy (70%).

    BACKGROUND Piercings are body embellishments commonly seen in young people, however their inherent risk of infection and scarring disorders are less divulged. OBJECTIVE To evaluate the prevalence of body piercings among medical students and their possible dermatologic consequences. METHODS Cross-sectional study with 58 medical students, by means of a structured questionnaire covering socio-demographic characteristics, technical issues related to the piercing and characteristics of the dermatologic complications. RESULTS The sample was predominantly female (86.2%), with mean age 24 ± 3 years. The placement of the first piercing occurred during adolescence (median age 15), without medical supervision (91.4%) or knowledge of parents/guardians (74%). Most piercings were made of metal alloy/stainless steel, in a dumbbell model (51.7%), inserted in the umbilical area (53.5%) or ear (41.4%), with frequent cutaneous reactions in the first six months post-piercing. Hypertrophic scarring, pain, swelling and infection (p<0.05) had significantly higher frequencies among those with navel piercings. CONCLUSION Piercing insertion occurred during adolescence. Local inflammatory and infectious reactions were common. Scarring disorders and dermatitis appeared in the long term. There is need for preventive and educational activities, starting with those in the academic environment. PMID:25387495

    Pierce's Disease (PD) of grapevines, caused by Xylella fastidiosa subsp. fastidiosa (Xf), is a limiting factor in the cultivation of grapevines in the US. There are presently no effective control methods to prevent or treat PD. The therapeutic and prophylactic efficacy of a phage cocktail composed of four virulent (lytic) phages was evaluated for control of PD. Xf levels in grapevines were significantly reduced in therapeutically or prophylactically treated grapevines. PD symptoms ceased to progress one week post-therapeutic treatment and symptoms were not observed in prophylactically treated grapevines. Cocktail phage levels increased in grapevines in the presence of the host. No in planta phage-resistant Xf isolates were obtained. Moreover, Xf mutants selected for phage resistance in vitro did not cause PD symptoms. Our results indicate that phages have great potential for biocontrol of PD and other economically important diseases caused by Xylella. PMID:26107261

    2009-11-01

    Laser piercing is one of the inevitable requirements of laser profile cutting process and it has a direct bearing on the quality of the laser cut profiles. We have developed a novel power ramped pulsed mode (PRPM) laser piercing technique to produce much finer pierced holes and to achieve a better control on the process parameters compared to the existing methodology based on normal pulsed mode (NPM). Experiments were carried out with both PRPM and NPM laser piercing on 1.5-mm-thick mild steel using an in-house developed high-power transverse flow continuous wave (CW)-CO 2 laser. Significant improvements in the spatter, circularity of the pierced hole and reproducibility were achieved through the PRPM technique. We studied, in detail, the dynamics of processes involved in PRPM laser piercing and compared that with those of the NPM piercing.

    Piercing has become a widespread fashion trend in Western industrialized nations within recent years. The invasive application of ornaments through cutaneous and mucosal surfaces enables the penetration of various pathogens into subcutaneous tissue. The authors describe the hazards of piercing and facial body art as they apply to 3 patients. Perichondrial auricular abscess, granulomatous perichondritis of the nasal ala, and embedding of a stud in the lower lip were the respective diagnoses. Literature was reviewed for the cultural origins and current practices of piercing, the legal background of piercing as a business, typical medical complications, and treatment recommendations. Numerous communications have been published on medical complications of piercing. The patients presented and the review of the literature illustrate that piercing is not a harmless fashion and that regulations of piercing as a business seem desirable to prevent further complications.

    2007-02-27

    An oscillator circuit is disclosed which can be formed using discrete field-effect transistors (FETs), or as a complementary metal-oxide-semiconductor (CMOS) integrated circuit. The oscillator circuit utilizes a Pierce oscillator design with three inverter stages connected in series. A feedback resistor provided in a feedback loop about a second inverter stage provides an almost ideal inverting transconductance thereby allowing high-Q operation at the resonator-controlled frequency while suppressing a parasitic oscillation frequency that is inherent in a Pierce configuration using a "standard" triple inverter for the sustaining amplifier. The oscillator circuit, which operates in a range of 10 50 MHz, has applications for use as a clock in a microprocessor and can also be used for sensor applications.

    2013-10-18

    Surface-piercing vegetation often captures particles that flow on the water surface, where surface tension forces contribute to capture. Yet the physics of capillary capture in flow has not been addressed. Here we model the capture of floating particles by surface-piercing collectors at moderately low Reynolds numbers (Re<10). We find a trade-off between the capillary force, which increases with the collector diameter, and the relative size of the meniscus, which decreases with the collector diameter, resulting in an optimal collector diameter of ~1-10 mm that corresponds to the regime in which many aquatic plant species operate. For this diameter range the angular distribution of capture events is nearly uniform and capture can be orders of magnitude more efficient than direct interception, showing that capillary forces can be major contributors to the capture of seeds and particulate matter by organisms.

    Oral piercing is a practice that has gained acceptance as a sign of individuality, marginality, decoration or group membership. In spite of its banal appearance, as seen in various scientific studies, piercing is not without risks. Complications include infection, bleeding and local trauma, which are frequent enough to raise questions about the safety and dangers of piercing. The case presented here revealed marked gingival recession accompanied by substantial bone loss caused by piercing the lower lip and tongue. Dental practitioners should be aware of the increasing number of patients with pierced intraoral and perioral sites and be prepared to provide appropriate guidance to patients who contemplate body piercing that involves oral sites.

    Previous studies have shown that older children gesture more while telling a story than younger children. This increase in gesture use has been attributed to increased story complexity. In adults, both narrative complexity and imagery predict gesture frequency. In this study, we tested the strength of three predictors of children's gesture use in a narrative context: age, narrative complexity (measured by discourse connectors), and use of imagery (measured by story length). French-, Spanish-, and English-speaking children between 4 and 10 years participated in this study. Including these three groups allows us to test for the generalizability of our results and for cross-linguistic differences in gesture frequency. All the children watched cartoons and retold the story. The results showed that the length of the story was a significant predictor of children's gesture rate while age and discourse connectors were not. There were no differences between language groups. One possible in interpretation of these results is that children's gesture frequency is strongly linked to activation of imagery.

    Background Studies in high-income countries have shown inverse associations between adiposity and cognitive performance in children. We aimed to examine the relationship between adiposity and cognitive function in Indian children. Methods At a mean age of 9.7 years, height, weight, triceps and subscapular skinfold thicknesses and waist circumference were recorded for 540 children born in Mysore, India. Body fat percentage was estimated using bio-impedance. Cognitive function was assessed using 3 core tests from the Kaufman Assessment Battery for children-II edition and additional tests measuring learning, short-term memory, reasoning, verbal and visuo-spatial abilities, attention and concentration. Data on the parents’ socio-economic status, education, occupation and income were collected. Results According to WHO definitions, 3.5% of the children were overweight/obese (BMI>+1SD) and 27% underweight (BMI<−2SD). Compared to normal children, overweight/obese children scored higher in tests of learning/long-term retrieval, reasoning and verbal ability (unadjusted p<0.05 for all). All the cognitive test scores increased with increase in BMI and skinfold thickness, (unadjusted β=0.10 to 0.20 SD; p<0.05 for all). The effects, though attenuated, remained mainly significant after adjustment for age, sex and socio-economic factors. Similar associations were found for waist circumference and percentage body fat. Conclusions In this Indian population, in which obesity was uncommon, greater adiposity predicted higher cognitive ability. These associations were only partly explained by socio-economic factors. Our findings suggest that better nutrition is associated with better cognitive function, and that inverse associations between adiposity and cognitive function in high-income countries reflect confounding by socio-economic factors.

    Schools at all levels welcome a visit from Antarctic research scientists who can combine science, a tale of adventure and cute pictures of penguins, but how can this opportunity be used to build an activity that lasts longer than a one hour visit? In the UK some primary schools have adopted a methodology termed 'Mantle of the Expert' in which the class do all their curriculum work as if they are an imagined group of experts. The approach allows different areas of the curriculum to be brought together in a challenging but fun activity. This paper will describe 'An Antarctic Quest: the Mystery of the Box' in which a class of 28 children were given the imaginary challenge of recovering an equipment box buried in Antarctica. To complete the task, the children found themselves investigating glaciology, climate, geography, history, international politics, clothing technology and transport. A few can now imagine themselves as Antarctic scientists.

    Toxic epidermal necrosis is a severe mucocutaneous disease with a high mortality rate. A third of the patients surviving the acute phase will develop pulmonary complications. The most frequent complication is bronchiolitis obliterans. Despite well-conducted treatment, in most cases, lung injury often leads to chronic respiratory failure. We describe here the case of a young patient that presented a toxic epidermal necrosis at the age of 3 years. Poor therapeutic compliance result in chronic respiratory failure and after 7 years of follow-up, pulmonary transplant remains the only long-term alternative. Close monitoring of respiratory symptoms in the course of toxic epidermal necrosis, intense treatment as soon as they appear and a long-term follow-up are essential to postpone chronic respiratory failure.

    Reported in the statistics of the Southern California Graphesthesia Test are significant sex differences for certain young age groups, with females scoring higher than males. In contrast, another study has reported that adult males scored higher than females on the same test. The purpose of this study was to examine the interaction between sex and age and to investigate a possible explanation for this interaction. Sixty-four normal children between the ages of 6.0 and 7.0 years, and 10.0 and 11.0 years were administered two graphesthesia tasks. One task was an adaptation of the Graphesthesia Test of the Southern California Sensory Integration Test (SCSIT). In this task, shapes were drawn sequentially on the palmar surface of the child's hand. A second task was devised whereby each of the same shapes was presented in a simultaneous manner, that is, the entire outline of each shape was pressed onto the palmar surface of the child's hand. Results indicated that for both tasks, younger boys performed relatively less ably than girls, but older boys equalled or surpassed the girls. At a level approaching significance, females scored relatively higher than males on the sequential task, and males scored relatively higher than females on the simultaneous task. However, this tendency toward an interaction between sex and the type of task does not fully explain the interaction between sex and age on graphesthesia tasks.

    2016-07-01

    There are few data in the literature on microscopic gastritis and colitis in the pediatric population. The diagnosis is often made after the occurrence of complications. We report the case of a 10.5 year-old girl for whom the diagnosis was made several years after the initial symptoms. Test for infections, inflammation, and auto-immunity yielded normal results. Upper endoscopy and colonoscopy revealed an abnormal mucosa. However, histology showed microscopic inflammation and fibrotic lesions in the lamina propria, and a thick subepithelial collagenous band. This led to the diagnosis of collagenous gastritis and colitis. Budesonide treatment resulted in the cessation of diarrhea and significant weight gain. Treatment by oral budesonide indeed seems to be highly effective but relapses are frequent when the treatment is stopped. This case shows the importance of being vigilant regarding transit disorders with impact on growth kinetics. Upper endoscopy and colonoscopy need to be carried out when children have organic diarrhea with normal blood tests. PMID:27266639

    Data from the 10-year follow-up of the 1970 British Births Survey were examined for associations between motor performance and dyslexia. Five tests of motor performance were used: (a) balancing on one leg, (b) throwing a ball in the air, clapping and catching it, (c) walking backwards, (d) sorting matches and (e) graphaesthesia (recognizing shapes drawn on the palm of the hand). These tests were given to 12 950 children aged between 10 and 11 years old. The cohort was divided into nine groups based on three levels of literacy achievement and three levels of possible indicators of dyslexia. The group with the most severe underachievement and most possible indicators (children most likely to be severely dyslexic) comprised about 2% of the total. Of this group, 35.3% failed one motor test and 16.4% failed more than one (51.7% in total), compared with 26.8% and 7.7% of normal achievers. The children had greater problems with balance than those in the other two severely underachieving groups but the effects were small. It is suggested that the use of a balance test only as a screener for dyslexia could result in a proportion of dyslexics being missed and that remedial motor training programmes for children with dyslexia should be offered only to those with co-occurring motor difficulties.

    Day-to-day variability and stability of children’s physical activity levels across days of the week are not well understood. Our aims were to examine the day-to-day variability of moderate-to-vigorous physical activity (MVPA), to determine factors influencing the day-to-day variability of MVPA and to estimate stability of MVPA in children. The sample comprises 686 Portuguese children (10 years of age). MVPA was assessed with an accelerometer, and BMI was computed from measured height and weight. Daily changes in MVPA and their correlates (gender, BMI, and maturity) were modeled with a multilevel approach, and tracking was calculated using Foulkes & Davies γ. A total of 51.3% of boys and 26.2% of girls achieved 60 min/day of MVPA on average. Daily MVPA was lower during the weekend (23.6% of boys and 13.6% of girls comply with the recommended 60 min/day of MVPA) compared to weekdays (60.8% and 35.4%, boys and girls, respectively). Normal weight children were more active than obese children and no effect was found for biological maturation. Tracking is low in both boys (γ = 0.59 ± 0.01) and girls (γ = 0.56 ± 0.01). Children’s MVPA levels during a week are highly unstable. In summary, boys are more active than girls, maturation does not affect their MVPA, and obese children are less likely to meet 60 min/day of MVPA. These results highlight the importance of providing opportunities for increasing children’s daily MVPA on all days of week, especially on the weekend. PMID:26262632

    Fatness generally has a negative influence on the performance of a variety of motor and cardiorespiratory fitness tests. The aim of this comparison was to analyse the effects of three grades of obesity on somatic growth, physical performance and oxygen consumption during exercise. Volunteer boys with definitely different grades of obesity were recruited for the comparison. In the group of mildly obese children (G1; n=23) BMI ranged between 24 kg.m -2 and 26 kg.m -2 ; and individual percent body fat was between 33% and 33.5%. In the case of moderate obesity (G2; n=23) BMI ranged between 26.5 kg.m -2 and 28.5 kg.m -2 ; and percent body fat was between 35% and 36%. In the extremely obese group (G3; n=20) BMI was greater than 31 kg.m -2 ; percent body fat was greater than 37.5%. Oxygen consumption during the 1,200 m run-test was measured by VIMEX-ST-type (USA) telemetric equipment.The greatest absolute aerobic power referred to the G3 boys, and the lowest oxygen consumption was characteristic of the mildly obese group. The very high differences between the body mass means resulted in a more marked inter-group variability in mean relative oxygen uptake.The predicted relative fat and high body fat content observed on the trunk, and the elevated level of resting blood pressure may indicate serious risks for the development of cardio-respiratory and metabolic disease. The very low oxygen consumption relative to body mass and poor physical performance are expected consequences of physiologic and environmental influences on the obese population.

    The purpose of this work was to verify in vitro adherence of E. corrodens and S. oralis to the surface of tongue piercings made of surgical steel, titanium, Bioplast, and Teflon. For this, 160 piercings were used for the count of Colony Forming Units (CFU) and 32 piercings for analysis under scanning electron microscopy. Of these, 96 (24 of each type) were individually incubated in 5 mL of BHI broth and 50 μL of inoculum at 37°C/24 h. The other 96 piercings formed the control group and were individually incubated in 5 mL of BHI broth at 37°C/24 h. Plates were incubated at 37°C/48 h for counting of CFU/mL and data were submitted to statistical analysis (p value <0.05). For E. corrodens, difference among types of material was observed (p < 0.001) and titanium and surgical steel showed lower bacterial adherence. The adherence of S. oralis differed among piercings, showing lower colonization (p < 0.007) in titanium and surgical steel piercings. The four types of piercings were susceptible to colonization by E. corrodens and S. oralis, and bacterial adhesion was more significant in those made of Bioplast and Teflon. The piercings presented bacterial colonies on their surface, being higher in plastic piercings probably due to their uneven and rough surface. PMID:27725949

    Summary Objective Specific regulations about education and training for body piercing licensure courses have to be considered due to the great increase in oral piercing practices. The aim of the present survey was to assess the local and systemic risk awareness in the practice of oral piercing and their prevention in a sample of Italian piercers. Materials and methods An anonymous 20-item questionnaire was administered to 30 body licensed piercers in a small town of central Italy. Licenses certificates were issued by Lazio Region after the completion of an approved training program for standard body piercing including 90 hours of course and a final examination as provided by regional law. The questionnaire surveyed on oral cavity anatomy, local and systemic risks as result of oral piercing, piercing maintenance and need of a dental visit. Results Response rate was 66.6%. Only 20% of respondents was aware about oral cavity anatomy and none had knowledge about tongue and gums anatomy. Only 10% enlightened the need of a dental visit and 30% was aware about piercingrelated temporary paralysis. The piercing maintenance was habitually proposed only by 40% of respondents. Conclusion The study participants showed a low level of awareness regarding the potential health risks of oral piercing. Poor knowledge of anatomy and local and systemic risks and poor awareness of the importance of piercing maintenance explanation. PMID:25774247

    We study the chaotic dynamics of the Pierce diode, a simple spatially extended system for collisionless bounded plasmas, focusing on the concept of edge of chaos, the boundary that separates transient from asymptotic dynamics. We fully characterize an interior crisis at the end of a periodic window, thereby showing direct evidence of the collision between a chaotic attractor, a chaotic saddle, and the edge of chaos, formed by a period-3 unstable periodic orbit and its stable manifold. The edge of chaos persists after the interior crisis, when the global attractor of the system increases its size in the phase space.

    Evaluation of water status in Jonathan apples was performed for 20 days. Loss moisture content (LMC) was carried out through slow drying of wholes apples and the moisture content (MC) was carried out through oven drying and lyophilisation for apple samples (chunks, crushed and juice). We approached a non-destructive method to evaluate LMC and MC of apples using image processing and multilayer neural networks (NN) predictor. We proposed a new simple algorithm that selects the texture descriptors based on initial set heuristically chosen. Both structure and weights of NN are optimised by a genetic algorithm with variable length genotype that led to a high precision of the predictive model (R(2)=0.9534). In our opinion, the developing of this non-destructive method for the assessment of LMC and MC (and of other chemical parameters) seems to be very promising in online inspection of food quality.

    NASA Astrophysics Data System (ADS)

    Chiodi, F.; Roman, B.; Bico, J.

    2010-05-01

    The hairs of a painting brush withdrawn from a wetting liquid self-assemble into clumps whose sizes rely on a balance between liquid surface tension and hairs bending rigidity. Here we study the situation of an immersed carpet in an evaporating liquid bath: the free extremities of the hairs are forced to pierce the liquid interface. The compressive capillary force on the tip of flexible hairs leads to buckling and collapse. However we find that the spontaneous association of hairs into stronger bundles may allow them to resist capillary buckling. We explore in detail the different structures obtained and compare them with similar patterns observed in micro-structured surfaces such as carbon nanotubes "forests".

    This study aimed to explore the current practice of performing high ear-piercing regarding consent protocols, and methods of practice using questionnaire-based survey in Hertfordshire and North London. Recommendations for good clinical practice are also made. 100 establishments performing ear piercing were identified. A 16-item questionnaire on techniques used, methods of high-ear piercing, methods of sterilization, consent issues and aftercare was completed. Seventy-six establishments agreed to participate. All practitioners prepared the skin before piercing. 58 (76%) used a needle for piercing, 11 (15%) used a spring-loaded gun and seven (9%) used both. 97% of the practitioners obtained written consent before proceeding. 9 (12%) had a lower age limit of 16 years and three (4%) of 18 years. 27 piercers (36%) provided an aftercare leaflet, 41 (54%) warned the patients about risks of infection, 16 (21%) warned about cosmetic deformity and 1 (1%) specifically mentioned cauliflower ear. Results indicated that high ear piercing is an invasive procedure with a significant risk of complications leading to cosmetic deformity. Establishments should be required to counsel patients properly about the risks and potential complications of the procedure. A code of practice should be drawn up with a minimum age for piercing, requirement for proper consent, excellent hygiene and good information for postoperative care.

    We aimed to investigate the association of psychopathology with tattooing and body piercing among adolescents in Istanbul by means of self-report questionnaires. Tenth, eleventh and twelfth grade students from 2 high schools in Istanbul with a total number of 607 participated in the study. The Youth Self Report, Children's Depression Inventory and a detailed semi-structured inquiry assessing tattooing, body piercing and some psychiatric and psychosocial variables were administered to the students. The prevalence of tattooing and body piercing were 4.8 and 7 %, respectively. The adolescents with tattooing and body piercing were found to have a higher frequency of alcohol and drug use, smoking, going to bars/night clubs and lower school grades when compared to those without tattooing and body piercing. Externalizing problems, mainly delinquent and aggressive behaviours were more prominent in the adolescents with tattooing and body piercing. Tattooing and body piercing in adolescents may be indicative of mental health risks.

    The cause of behavioural changes described by Alzheimer for his original case, Auguste D., has been recently reconfirmed by histological examination. However, there has been active speculation regarding the cause of behavioural changes exhibited by the political satirist Jonathan Swift (1667-1745) during the final three years of his life for over 250 years. Swift's symptoms of cognitive changes, memory impairment, personality alterations, language disorder and facial paralysis have all been apportioned differing levels of significance in various attempts at retrospective diagnosis. The various medical arguments put forward from the 18th through 20th centuries will be critically examined. The diagnoses considered refer to evolving theories of insanity, phrenology, localization of cortical function, hydrocephalus, psychoanalysis, aphasia, dementia and depression in ageing. Re-consideration of the attempts to re-diagnose Swift's final mental state by the leading neurological thinkers of the day, including Wilde (The Closing Years of Dean Swift's Life. Dublin: Hodges and Smith, 1849), Bucknill (1882), Osler [Osler's textbook Principles and Practice of Medicine (1892); published in St Thomas's Hospital Gazette (London) 1902; 12: 59-60), Brain (Irish Med J 1952: 320-1 and 337-346) and Boller and Forbes (J Neurol Sci 1998; 158: 125-133) reveal the changing attitudes regarding the significance of behavioural symptoms to neurological diagnosis from the 18th century to the present day.

    250 years ago, the satirical writer and clergyman Jonathan Swift from Dublin (1667-1745) founded the first Irish lunatic asylum. Rejecting the theories put forward by the English philosopher Thomas Hobbes and the doctor Thomas Willis, he was influenced by the ideas of the Scottish doctor and the "enlightened" thinker John Locke. Swift's St. Patrick's Hospital did not, however, realise a new philosophical concept: architecture and therapeutic approach of the new institution were clearly modelled on the much older Hospital of St. Mary of Bethlehem ( = Bedlam). Despite its conservative conceptual basis, the first institution dedicated to the mentally ill and intellectually subnormal in Ireland became a starting point for the apparantly unstoppable expansion of the, at one time, most comprehensive asylum system in the world. After Swift's Hospital had been enlarged twice at the tax-payers' expense (1778, 1793), the administration decided to relieve the institution by erecting the Richmond Asylum (1810), the first public asylum in Ireland. When this establishment also became overcrowded, in 1817, legislation was passed which led to the establishment of the oldest system of public asylums in Europe.

    In 1833 an accomplished 26-year-old linguist suffered a non-paralytic stroke. After he recovered, though he could utter a variety of syllables with ease, he spoke an unintelligible jargon that caused him to be mistaken as a foreigner. He was examined repeatedly over the course of a year by Jonathan Osborne (1794-1864), a Dublin physician and professor of materia medica, who found that the patient understood whatever was said to him, that he could read and write fluently, but had difficulty repeating words read to him or in reading aloud. Osborne recommended that he learn to speak English, his natural language, de novo and over 8 months measured his considerable improvement. To explain the patient's singular difficulty in repeating spoken words Osborne argued it was 'highly probable that, having been conversant with five languages, the muscular apparatus ranged among them, forming a kind of polyglot jargon [that was] wholly unintelligible' and the patient was 'unable to penetrate into and select the contents of the store according as the [words] were required'. The discrepancy between comprehension and repetition was later termed conduction aphasia. PMID:21052861

  10. Plant cell piercing by a predatory mite: evidence and implications.

    PubMed

    2015-02-01

    Omnivorous arthropods can play an important role as beneficial natural enemies because they can sustain their populations on plants when prey is scarce, thereby providing prophylactic protection against an array of herbivores. Although some omnivorous mite species of the family Phytoseiidae consume plant cell-sap, the feeding mechanism and its influence on the plant are not known. Using scanning electron microscopy we demonstrated that the omnivorous predatory mite Euseius scutalis penetrates epidermal cells of pepper foliage and wax membranes. Penetration holes were teardrop shape to oval, of 2-5 µm diameter. The similarities between penetration holes in pollen grains and in epidermal cells implied that the same penetration mechanism is used for pollen feeding and plant cell-sap uptake. Variation in shape and size of penetration holes in leaves and a wax membrane were attributed to different mite life stages, depth of penetration or the number of chelicerae puncturing (one or both). Punctured stomata, epidermal and vein cells appeared flat and lacking turgor. When the mite penetrated and damaged a single cell, neighboring cells were most often intact. In a growth chamber experiment very large numbers of E. scutalis negatively affected the growth of young pepper plants. Consequently caution should be taken when applying cell-piercing predators to young plants. Further studies are needed to take advantage of the potential sustainability of plant cell-sap feeding predators.

    The specification of left-right asymmetry of the visceral organs is precisely regulated. The earliest breakage of left-right symmetry occurs as the result of leftward flow generated by asymmetric beating of nodal cilia, which eventually induces asymmetric Nodal/Lefty/Pitx2 expression on the left side of the lateral plate mesoderm. PIERCE1 has been identified as a p53 target gene involved in the DNA damage response. In this study, we found that Pierce1-null mice exhibit severe laterality defects, including situs inversus totalis and heterotaxy with randomized situs and left and right isomerisms. The spectrum of laterality defects was closely correlated with randomized expression of Nodal and its downstream genes, Lefty1/2 and Pitx2. The phenotype of Pierce1-null mice most closely resembled that of mutant mice with impaired ciliogenesis and/or ciliary motility of the node. We also found the loss of asymmetric expression of Cerl2, the earliest flow-responding gene in the node of Pierce1-null embryos. The results suggest that Pierce1-null embryos have defects in generating a symmetry breaking signal including leftward nodal flow. This is the first report implicating a role for PIERCE1 in the symmetry-breaking step of left-right asymmetry specification. PMID:27305836

    Tattoos and piercings are increasing, especially among youths, but the risk of hepatitis C virus (HCV) infection from these practices has not been adequately assessed and there are conflicting findings in the literature. We evaluated the risk of HCV infection from tattooing and piercing using the Meta-analysis of Observational Studies in Epidemiology (MOOSE) guidelines. Studies that specified the venue of tattooing and/or piercing showed no definitive evidence for an increased risk of HCV infection when tattoos and piercings were received in professional parlors. However, the risk of HCV infection is significant, especially among high-risk groups (adjusted odds ratio, 2.0-3.6), when tattoos are applied in prison settings or by friends. Prevention interventions are needed to avoid the transmission of hepatitis C from tattooing and piercing in prisons, homes, and other potentially nonsterile settings. Youths also should be educated on the need to have tattoos and piercings performed under sterile conditions to avoid HCV infection. PMID:22291098

    Abstract Hepatitis B and hepatitis C are 2 types of potentially life-threatening liver diseases with high infection rate. Body piercing represents a progressively popular sociocultural phenomenon which is also a potential exposure approach for hepatitis B virus (HBV) and hepatitis C virus (HCV). Conclusions from those researches with statistically risk assessment of body piercing on HBV and HCV transmission are contradictory. Systematically analyze the association between body piercing and the risk of transmitting hepatitis B virus and hepatitis C virus for general population. Make evidence-based recommendations to the current practice and wake up public awareness of this health-threatening behavior. Comprehensive and high sensitivity search strategies were performed to exhaustively search related studies before 15 January 2015 (MEDLINE, EMBASE, WANFANG, CNKI datasets for published literatures, and Google and Google scholars for related grey articles). Two authors identified relevant studies for the review, abstracted data, and assessed literature quality independently and critically according to the selection criteria and quality assessment standard. Odds ratio (OR) and corresponding 95% confidence interval (CI) were used to estimate risk of HBV and HCV infection in relation to body piercing status. Subgroup analysis and sensitivity analysis were conducted to examine the source of heterogeneity and test the robust of the results. A total of 40 studies were included in this systematic review (10 for Hep-B, 26 for Hep-C, 4 for both Hep-B and Hep-C), the pooled OR (95% CI) for the association between body piercing and transmission of HBV/HCV is 1.80 (1.18, 2.75) and 1.83 (1.27, 2.64), respectively. Subgroup analysis suggested that highest risk of body piercing related to hepatitis C infection was for former soccer and veterans with OR of 4.63 (2.65, 8.10), while strongest association between body piercing and hepatitis B was for samples derived from students

    In this work three capsule-based dry powder inhalers, available for generics product development, were compared. Two technologically different dry powder formulations were used in order to relate the capsule piercing position and motion in the device to their aerodynamic performance. A "pierce and inhale" design, in which the capsules pierced with RS01, HandiHaler or Turbospin devices were aerosolized in the same device or transferred and aerosolized with another device, was constructed and carried out. The results obtained showed that two dry powder formulations, i.e., a drug/lactose blend or a carrier-free powder, aerosolized using capsule based inhalers, performed differently. The aerosolization of drug carrier mixture in terms of drug dispersion and emitted dose, was more sensible to the piercing and device combination than the carrier free powder. The motion of the capsule during the aerosolization boosted the powder emission, whereas the powder disaggregation was more influenced by the airflow pattern around the capsule and inside the inhaler turbulence chamber.

  17. Self-Pierce Riveting Through 3 Sheet Metal Combinations

    One way to reduce the CO{sub 2} emissions in automotives is to reduce the weight of the Body-In-White. One easy to achieve the weight reduction is to replace steel sheet materials with Al alloys, which is 3 times lighter. One issue is the joining process, especially with combinations between steel grades and AL alloys. Example of combination of mixed material combinations (Al-steel) might be found in the door structure. The reason is because of the AL alloys worthier crash performance so the automotive manufacturer might want to use crash impact beams made by high strength steels in a AL intensive door structure. The joining process between aluminum and steel are problematic due it's not possible to use traditional spot-welding technologies due to the materials total difference in microstructure characteristics as well thermal properties. To overcome this issue then mechanical as well adhesion joining are frequently used. This paper describes a development process and subsequently analysis of a self-pierce rivet (SPR) process between 3 sheet metal combinations. The multi-material combinations in this study were a combination of ultra high strength steels sheets (DP1000) and a Al-alloy (AA 6014). The analysis of the SPR process, in sense of mechanical strengths, has been done by peel- and shear tests. To reduce the amount of future physical tests a virtual FE-model has been developed for the process. This FE model of the process has been subsequently used to analyze the mechanical strength during plastic deformation. By using inverse analysis a correct contact algorithm has been evaluated that would predict the binding force between the rivet and sheet under a deformation process. With this new virtual model it will not only possible to analyze and develop the SPR process but also to achieve the final strength of the joint.

  18. A study of the zona piercing process in piezodriven intracytoplasmic sperm injection

    2008-08-01

    The mouse zona piercing process in piezodriven intracytoplasmic sperm injection (piezo-ICSI) is modeled and simulated with the material point method (MPM) to study the physics behind the piercing process. The MPM simulation reveals that the lateral vibration of the injection pipette plays a key role in the piercing process and disproves the claim that the axial displacement of the pipette pierces the zona. The lateral vibration of the injection pipette is further analyzed using the finite element method to investigate the role of mercury in the piercing process. It is shown that the use of mercury generally reduces the amplitude of the pipette tip and that a shorter piezopulse duration results in a smaller vibration amplitude. This implies that the effect of mercury on the piezo-ICSI procedure may lie in causing less oocyte damage due to the reduced amplitude of the pipette tip, and the development of a piezo-ICSI procedure without using mercury is possible by changing the dimensions of the injection micropipette and the piezodrill controller parameters.

    Chitinozoans are an extinct group of organic microfossils of uncertain biological affinity. In shape, they resemble minute (50{mu}m-2,000{mu}m) flasks and vases. Chitinozoan fossils occur in marine sedimentary rocks ranging from Cambrian to Carboniferous in age. Chitinozoan diversity is low in the Ridley and Pierce Limestones. Thirteen taxa were identified; two were left in open nomenclature, and one (Conochitina ridleyensis) is provisionally considered to be a new species. Low chitinozoan abundance and the sporadic distribution of chitinozoans in the Ridley and Pierce Limestones is believed to be the result of variable environmental conditions associated with a marine, shallow-shelf environment. The short-ranging chitinozoan taxa Lagenochitina baltica, Conochitina robusta, and Rhabdochitina turgida allow an accurate age assignment to be made for the Ridley and Pierce Limestones. These formations can now be correlated with the Conochitina hirsuta-Lagenochitina sp. A biozone, indicating an upper Blackriveran (mid-Caradocian) age assignment.

    Three aluminium alloy and steel sheets were joined with a self-piercing rivet. Self-pierce riveting has the function of joining steel and aluminium alloys having very different melting points due to plastic joining. The requisites for joining the three sheets are the driving of the rivet leg through the middle sheet, the flaring of the rivet leg in the lower sheet and the prevention of the fracture of the lower sheet. The joinability for various combinations of the three sheets was determined. When the rivet leg is small, no driving through the middle sheet occurs, the lower sheet ruptures for a large rivet leg. In addition, 980 MPa high strength steel, mild steel and aluminium alloy sheets were joined by the self-pierce riveting.

  1. Response to Schaefer's Comments on Pierce & Jacoby (1995) Regarding the Type 1A Supernova 1937C

    1996-08-01

    We address Schaefer's [AJ, 111, 1668(1996)] criticisms of the photometry of the Type Ia supernova, SN 1937C, presented by Pierce & Jacoby [AJ, 110,2885 (1995)] in which they reanalyzed the photographic films of Baade & Zwicky [ApJ, 88,411(1938)]. Most of Schaefer's arguments were addressed by Pierce & Jacoby and shown to be either irrelevant or insignificant. Schaefer's principal argument centers on whether Beyer [AN, 268, 341(1939)] used day vision or night vision in his visual observations, and states that this issue affects Pierce & Jacoby' s photographically derived magnitudes so as to create errors up to 0.5 mag. However, Pierce & Jacoby's photographic analysis has no dependence on Beyer's data, and so Schaefer's point is immaterial. Nevertheless, in reviewing the Pierce & Jacoby analysis, we have identified a small potential Systematic error in the Pierce & Jacoby V magnitudes that may be as large as 0.15 mag 30 days after peak, approaching 0.0 mag close to peak. These deviations arise from the differences between the standard star and SNIa spectral energy distributions, and are far smaller than the 0.5 mag error near peak that Schaefer claims. Schaefer also claimed that Pierce & Jacoby used only a subset of the available data in fitting their light curve to templates. We demonstrate that restricting the fits to the data region near maximum light is essential or the derived peak magnitude will be systematically too bright because the templates overshoot the peak to compensate for undershooting at later times. Using all the data out to late times, as Schaefer proposes, introduces errors up to 0.2 mag. None of Schaefer's arguments affects the conclusions of Pierce & Jacoby more than ~2%. Thus, the best estimates for the peak B and V mags for SN 1937C remain 8.94+/-0.03 and 9.00+/-0.03. These values lead to H_0_ = 68+/-5 or 74+/-6 km/s/Mpc if the slopes of the decline rate relationship are 1.0 or 1.6, respectively, or H_0_ = 66+/-5 if the more recent slope of 0

    Mixed Pierce-two-stream instability may occur in an extraction system of a negative ion source based on a volume-produced plasma. The reasons for instability development are discussed. Analytically the conditions of unstable beam propagation are determined. The instability threshold is shown to be increased compared with the pure Pierce instability. The influence of inclined perturbations on the instability behavior is investigated. The numerical calculations are performed in COMSOL Multiphysics. The simulation results confirm the existence of such a mixed instability appearance that develops due to both the electrons of the external circuit and the background positive ions. PMID:26931917

    The purpose of this study was to describe correlates of sedentary behaviour (SED) in children at elevated risk of obesity because of parental obesity. Participants were 534 children aged 8-10 years with ≥ 1 obese parent. SED and physical activity (PA) were measured by accelerometer, screen time by self-report, and height, weight, waist circumference, and cardiovascular fitness objectively measured. Data describing the child, parents, friends, and home and neighbourhood environments were from child self-report. Higher total SED time was significantly positively associated with child's age, mother's age, Tanner stage, weight status or waist circumference, less self-reported PA, choosing screen time over PA/sport, mother saying PA/sport good for them, and fewer weekly physical education (PE) classes. Exceeding 2 h/day screen time was significantly associated with child's age, male sex, weight status or waist circumference, choosing screen time over PA/sport, and dinnertime TV viewing. Children regularly watching TV with dinner had 2.3 times greater odds (95% confidence interval (CI) 1.52, 3.58) of exceeding screen time guidelines compared with children rarely watching TV with dinner; children reporting ≤ 2 PE classes/week had 2.4 times greater odds (95% CI 1.41, 4.10) of being in the highest SED tertile compared with children reporting >2 PE classes/week. Hence, the most sedentary children are older, more biologically mature, less active, more overweight/obese, have fewer PE classes, and are more likely to choose screen time over PA and watch TV with dinner compared with less sedentary children. PE opportunities and mealtime TV viewing are potentially modifiable targets for reducing total SED and screen time in children. PMID:25415850

  7. Persistence of 10-year old Exxon Valdez oil on Gulf of Alaska beaches: The importance of boulder-armoring

    2006-01-01

    Oil stranded as a result of the 1989 Exxon Valdez spill has persisted for >10 years at study sites on Gulf of Alaska shores distant from the spill's origin. These sites were contaminated by "oil mousse", which persists in these settings due to armoring of underlying sediments and their included oil beneath boulders. The boulder-armored beaches that we resampled in 1999 showed continued contamination by subsurface oil, despite their exposure to moderate to high wave energies. Significant declines in surface oil cover occurred at all study sites. In contrast, mousse has persisted under boulders in amounts similar to what was present in 1994 and probably in 1989. Especially striking is the general lack of weathering of this subsurface oil over the last decade. Oil at five of the six armored-beach sites 10 years after the spill is compositionally similar to 11-day old Exxon Valdez oil. Analysis of movements in the boulder-armor that covers the study beaches reveals that only minor shifts have occurred since 1994, suggesting that over the last five, and probably over the last 10 years, boulder-armors have remained largely unmoved at the study sites. These findings emphasize the importance of particular geomorphic parameters in determining stranded oil persistence. Surface armoring, combined with stranding of oil mousse, results in the unexpectedly lengthy persistence of only lightly to moderately weathered oil within otherwise high-energy wave environments. ?? 2006 Elsevier Ltd.

    The relationship between exposure to electromagnetic fields from non-ionizing radiation and adverse human health effects remains controversial. We aimed to explore the association of environmental radiofrequency-electromagnetic fields (RF-EMFs) exposure with neurobehavioral function of children. A subsample of 123 boys belonging to the Environment and Childhood cohort from Granada (Spain), recruited at birth from 2000 through 2002, were evaluated at the age of 9-11 years. Spot electric field measurements within the 100 kHz to 6 GHz frequency range, expressed as both root mean-square (S(RMS) and maximum power density (S(MAX)) magnitudes, were performed in the immediate surrounds of childreńs dwellings. Neurocognitive and behavioral functions were assessed with a comprehensive battery of tests. Multivariate linear and logistic regression models were used, adjusting for potential confounders. All measurements were lower than reference guideline limits, with median S(RMS) and S(MAX) values of 285.94 and 2759.68 μW/m(2), respectively. Most of the cognitive and behavioral parameters did not show any effect, but children living in higher RF exposure areas (above median S(RMS) levels) had lower scores for verbal expression/comprehension and higher scores for internalizing and total problems, and obsessive-compulsive and post-traumatic stress disorders, in comparison to those living in areas with lower exposure. These associations were stronger when S(MAX) values were considered. Although some of our results may suggest that low-level environmental RF-EMF exposure has a negative impact on cognitive and/or behavior development in children; given limitations in the study design and that the majority of neurobehavioral functioning tasks were not affected, definitive conclusions cannot be drawn.

    The increasing prevalence of childhood overweight and obesity has been associated with an increased risk for cardiovascular disease (CVD). While several studies examined the effect of single behaviors such as physical activity (PA), sedentary behavior or diet on CVD risk, there is a lack of research on combined associations, specifically in children. Therefore, the purpose of this study was to examine the joint association of PA or screen time (ST) and diet on CVD risk factors in children. PA, STand diet were assessed via questionnaire in 210 fifth grade students (age: 10.6 ± 0.4 years). The healthy eating index (HEI) was subsequently calculated as indicator for diet quality. Height, weight, % body fat, and resting blood pressure were measured according to standard procedures and blood samples obtained via fingerprick were assayed for blood lipids. Total cholesterol HDL ratio (TC:HDL), mean arterial pressure (MAP), and % body fat were used as indicators of CVD risk. 55% of children did not meet current PA recommendations on at least 5 days/week and 70% exceeded current recommendations for ST. Further, only 2.5% possessed a "good" diet (HEI> 80). There was no significant association of PA or STand diet on CVD risk score. Neither TC:HDL, MAP, and % body fat nor the total CVD risk score was significantly correlated with diet, PA, or ST. Children in the high PA group, however, had significantly better diet scores. Despite the fact that self-reported PA, ST, or dietary intake were not directly related to CVD risk in this sample, higher activity levels were associated with a healthier diet and lower ST indicating an overall healthier lifestyle of this subgroup.

  11. Proposal for a universal measurement system for school chairs and desks for children from 6 to 10 years old.

    2017-01-01

    In a primary education classroom of any country, children of the same age have very different statures, reaching variations of 200 mm (Gonçalves, 2012). However, the school furniture provided is not suitable or adaptable to these differences. Designing school furniture able to respond to these variations is, therefore, a challenge for ergonomics and design in a global market. It is clearly not viable for industries to adapt productions for each country. When competitiveness and limitation of resources are essential for the viability of any product it becomes essential to find a universal system adapted to the requisites of any country. Taking as prescription measure the popliteal height obtained from the data of different countries, a universal measurement system for the school chair and desk set is proposed, combining the ellipse methodology used by Molenbroek et al. (2003) and the (mis)match equations mentioned by Castellucci et al. (2014b). From the results obtained, it can be concluded that only 5 sizes are needed to implement this new measurement system of evolutionary school furniture for the primary education classroom.

    This study examines the association between objectively-measured physical activity (PA) intensities and sedentary behavior (SED) in a cohort of 532 children aged 8-10 y. PA and SED were assessed by accelerometer over 7-days. Television and computer/video-game use were self-reported. Associations between PA intensities and SED variables were assessed by Spearman correlations and adjusted multiple linear regression. Higher mean daily moderate-to-vigorous and vigorous PA (MVPA, VPA) were negatively associated with mean daily SED (r = -0.47 and -0.37; p < .001), and positively associated with mean daily total PA (r = .58 and 0.46; p < .001). MVPA was also positively associated with light PA (LPA; r = .26, p < .001). MVPA and VPA were not significantly associated with TV, computer/video or total screen time; accelerometer SED was only weakly associated with specific SED behaviors. On average, for each additional 10 min daily MVPA, children accumulated >14 min less SED, and for each additional 5 min VPA, 11 min less SED. Thus, over the course of a week, higher mean daily MVPA may displace SED time and is associated with higher total PA over and above the additional MVPA, due to concomitant higher levels of LPA. Public health strategies should target both MVPA and SED to improve overall PA and health in children. PMID:24018974

    1996-01-01

    After 10 years in Geo orbit, during the spring 1993 eclipse season, soft shorts occurred in cells of two of the three batteries on the F2R spacecraft On battery #1, the cell soft short turned suddenly into a hard short; the resulting sudden 1.2V fall in battery voltage and rise in temperature was observed via telemetry. On battery #3, the deleterious impact of its soft short increased day by day, manifesting itself as a drop in battery voltage part-way through each eclipse, causing high loading on the remaining good battery. This paper reports how by planned charge management, including applying (against-the-book) overcharge ratios (C/D) exceeding 1.75, the battery #3 cell soft short was 'built down' until the cell voltage fade ceased. The problem with the battery #3 soft-shorted cell was fought with partial success throughout the latter half of the fall 93 season, and the lessons learned were applied to alleviate the problem during the spring 94 and fall 94 eclipse seasons. The life of the spacecraft was successfully prolonged until it was retired in March 1995.

    Introduction: The premature loss of primary teeth may reduce arch length required for the succeeding tooth and, hence, predisposes crowding, rotation and impaction of the permanent teeth. There are only limited studies carried out about the prevalence of early loss of primary teeth. Aim: The present study was performed to evaluate the prevalence of early loss of primary teeth in school children in Chidambaram town in Tamilnadu, India. Settings and Design: A total of 1121 school children (561 boys and 560 girls) between 5 and 10 years of age were selected for the study. Materials and Methods: An experienced examiner performed all clinical examinations under natural light. Data including age and missing tooth was collected. Statistical Analysis Used: Microsoft Excel/2000 (Microsoft Office XP) data spreadsheet was used and later exported to the Statistical Package for Social Science (SPSS) for Windows (version 10.0). Descriptive statistics was applied and, from the results, chi-square tests were applied at a level of significance of 5% (P < 0.05). Results and Conclusions: The results showed that 16.5% of the sample had early loss of primary teeth, but no differences were observed between genders (P > 0.05). The greatest prevalence was found among the 8-year olds (5.08%), and the most commonly missing teeth were the right lower primary first molars (16.82%). It can be concluded that the prevalence of early loss was high and that the lower primary molars were the most commonly missing teeth in the present study PMID:22557893

    Reading disabilities are one of the most significant causes of school failure and may result from different causes and cognitive processes. A comprehensive battery of neuropsychological tests was applied to a control group of 102 children (46 girls, 56 boys) with no history of learning disabilities and 32 children (13 girls, 19 boys) with poor reading achievement (PRA) to characterize their cognitive profile. A principal component analysis of the cognitive measures was undertaken to identify cognitive domains. Age-adjusted normative data were computed from controls for verbal and visuospatial abilities, psychomotor skills, executive functions, and a total score. Significant differences were found between the 2 groups. Although single tests could not identify children with PRA, measures of oral and written language, immediate and working memory, calculation, and verbal learning discriminated the 2 groups. A logistic regression model using these factors allowed us to identify 91.2% of healthy children and 96.9% of children with PRA. PRA may result from different patterns of cognitive difficulties, and it is more common in children with oral language and working-memory deficits. Wide-range cognitive testing is necessary to identify strong and weak areas to plan personalized intervention programs. PMID:25117206

    1. Of the scarce Calyptra minuticornis, C. orthograpta and C. labilis, 51, 24, and 7 adults, respectively, were observed during some 600 night inspections at over 100 sites in 1965--1967 and 1971--1977. 2. Hitherto biologically completely unknown, and not recorded before in S.E. Asia, the latter two species flew in or near tropical monsoon forests in hilly regions (300--600 m) of N. Thailand (C. orthograpta also N. Laos). C. minuticornis was found in these and in tropical evergreen and semi-evergreen rain forests of S. Thailand and N.W. Malaysia. 3. In N. Thailand the three species were more common at the end of the cool season/start of the hot season and at the start of the rainy season. They were active mainly during the first half of the night 4. Flight and piercing behaviour, alighting, resting, enemies, and the lack of females, were similar to virtually identical with the "classical" skin-piercing blood-sucking C. eustrigata. 5. C. labilis was seen attacking elephant, C. orthograpta also water buffalo and sambar, C. minuticornis also zebu and tapir but not sambar. C. minuticornis settled on man also but did not pierce. 6. Through no piercing of hosts' skin has actually been seen in nature, indirect evidence suggests that the 3 moths are likely to be occasional blood-suckers. They pierced and sucked blood from the author's skin in experiments. 7. Reasons for lack of direct evidence may be: less developed hematophagy, less favoured hosts, lack of easy-to-pierce injured skin (which also trigger the piercing response), different climatic and phytoecological environment, fewer specimens than in the case of C. eustrigata. 8. Field observations and experiments indicate that the closely related, fruit-piercing Oraesia emarginata is not skin-piercing blood-sucking--a habit likely to be exhibited mainly in humid equatorial regions by a few Calyptra only.

    At present tattoos and piercings can no longer be regarded as destructive acts of self mutilation practized by fringe groups. Body modifications (BMs) are found in virtually all preindustrial cultures and have their roots in ancient myths and magical rituals. The prevalence of tattoos and piercings in the German population is 8.5% and 6.8%, respectively. Unemployed young men and young women who do not live in a firm partnership show particularly high prevalences. The incidence of BMs correlates positively with the personality trait "sensation seeking", particularly in young women. BMs often serve to express individuality and identity, and they also reflect changed attitude towards the human body and body art as well as following fashion trends. However, BMs can also provide valuable diagnostic indications for identity search and risk taking behaviour.

    First impressions based on practitioner appearance often form the basis for preliminary assumptions regarding trust, confidence, and competence, especially in situations where patients or family members do not have an established relationship with the physician. Given their growing prevalence, we strove to further investigate whether visible tattoos or piercings on a medical provider affects a patient's perception of the provider's capabilities and their trust in the care that would be provided. A survey using photographs of simulated practitioners was administered to 314 participants split between rural and urban locations. Study volunteers rated tattooed practitioners with lower confidence ratings when compared with nontattooed practitioners and reported greater degrees of discomfort with greater degrees of facial piercing. We concluded that these factors adversely affect the clinical confidence ratings of practitioners, regardless of the gender, age group, or location of participants.

    2006-11-01

    The possibility of modeling fast processes in the collisionless single-emitter plasma diode (Knudsen diode with surface ionization, KDSI) by means of the Pierce-diode is studied. The KDSI is of practical importance in that it is an almost exact model of thermionic energy converters (TICs) in the collisionless regime and can also be used to model low-density Q-machines. At high temperatures, the Knudsen TIC comes close to the efficiency of the Carnot cycle and hence is the most promising converter of thermal to electric energy. TICs can be applied as component parts in high-temperature electronics. It is shown that normalizations must be chosen appropriately in order to compare the plasma characteristics of the two models: the KDSI and the Pierce-diode. A linear eigenmode theory of the KDSI is developed. For both nonlinear time-independent states and linear eigenmodes without electron reflection, excellent agreement is found between the analytical potential distributions for the Pierce-diode and the corresponding numerical ones for the KDSI. For the states with electron reflection, the agreement is satisfactory in a qualitative sense. A full classification of states of both diodes for the regimes with and without electron reflection is presented. The effect of the thermal spread in electron velocities on the potential distributions and the (ɛ,η) diagrams is analyzed. Generally speaking, the methodology developed is usefully applicable to a variety of systems in which the electrons have beam-like distributions.

    Despite numerous studies on utilizing polymeric vesicles as nanocapsules, fabrication of tunable molecular pathways on transportable vesicle walls remains challenging. Traditional methods for building penetrated channels on vesicular membrane surface often involve regulating the solvent polarity or photo-cross-linking. Herein, we developed a neat, green approach of stimulation by using CO2 gas as “molecular drill” to pierce macroporous structures on the membrane of polymersomes. By simply introducing CO2/N2 gases into the aqueous solution of self-assemblies without accumulating any byproducts, we observed two processes of polymeric shape transformation: “gas breathing” and “gas piercing.” Moreover, the pathways in terms of dimension and time were found to be adjustable simply by controlling the CO2 stimulation level for different functional encapsulated molecules in accumulation, transport, and releasing. CO2-breathing and piercing of polymersomes offers a promising functionality to tune nanocapsules for encapsulating and releasing fluorescent dyes and bioactive molecules in living systems and also a unique platform to mimic the structural formation of nucleus pore complex and the breathing process in human beings and animals.

    The fastidious phytopathogenic bacterium, Xylella fastidiosa, poses a substantial threat to many economically important crops, causing devastating diseases including Pierce's Disease of grapevine. Grapevines (Vitis vinifera L.) planted in an area under Pierce's Disease pressure often display differences in disease severity and symptom expression, with apparently healthy vines growing alongside the dying ones, despite the fact that all the vines are genetic clones of one another. Under the hypothesis that endophytic microbes might be responsible for this non-genetic resistance to X. fastidiosa, endophytic fungi were isolated from vineyard cvs. 'Chardonnay' and 'Cabernet Sauvignon' grown under high Pierce's Disease pressure. A Cochliobolus sp. isolated from a Cabernet Sauvignon grapevine inhibited the growth of X. fastidiosa in vitro. Bioassay-guided isolation of an organic extract of Cochliobolus sp. yielded the natural product radicinin as the major active compound. Radicinin also inhibited proteases isolated from the culture supernatant of X. fastidiosa. In order to assess structure-activity relationships, three semi-synthetic derivatives of radicinin were prepared and tested for activity against X. fastidiosa in vitro. Assay results of these derivatives are consistent with enzyme inactivation by conjugate addition to carbon-10 of radicinin, as proposed previously. PMID:25892412

    Hepatitis B and hepatitis C are 2 types of potentially life-threatening liver diseases with high infection rate. Body piercing represents a progressively popular sociocultural phenomenon which is also a potential exposure approach for hepatitis B virus (HBV) and hepatitis C virus (HCV). Conclusions from those researches with statistically risk assessment of body piercing on HBV and HCV transmission are contradictory.Systematically analyze the association between body piercing and the risk of transmitting hepatitis B virus and hepatitis C virus for general population. Make evidence-based recommendations to the current practice and wake up public awareness of this health-threatening behavior.Comprehensive and high sensitivity search strategies were performed to exhaustively search related studies before 15 January 2015 (MEDLINE, EMBASE, WANFANG, CNKI datasets for published literatures, and Google and Google scholars for related grey articles). Two authors identified relevant studies for the review, abstracted data, and assessed literature quality independently and critically according to the selection criteria and quality assessment standard. Odds ratio (OR) and corresponding 95% confidence interval (CI) were used to estimate risk of HBV and HCV infection in relation to body piercing status. Subgroup analysis and sensitivity analysis were conducted to examine the source of heterogeneity and test the robust of the results.A total of 40 studies were included in this systematic review (10 for Hep-B, 26 for Hep-C, 4 for both Hep-B and Hep-C), the pooled OR (95% CI) for the association between body piercing and transmission of HBV/HCV is 1.80 (1.18, 2.75) and 1.83 (1.27, 2.64), respectively. Subgroup analysis suggested that highest risk of body piercing related to hepatitis C infection was for former soccer and veterans with OR of 4.63 (2.65, 8.10), while strongest association between body piercing and hepatitis B was for samples derived from students/community with OR of

    The present study examined the prevalence and acceptance of body piercings and tattoos among a community sample from the southern German-speaking area of Central Europe. A total of 440 respondents completed information about their own body piercings and tattoos and reported whether they would be likely never to have piercings and tattoos in the future. Analyses indicated that 19.8 and 15.2% of respondents had piercings (excluding the earlobe) and tattoos, respectively. Women were more likely to have body piercings than men, but there were no sex differences in tattooing. There were also few sociodemographic differences in piercings and tattoos, and most participants reported being likely to consider body art in the future. These results are considered in relation to prevalence estimates of body art in other Western countries and the associated health risks.

  19. Pierced Lasso Bundles Are a New Class of Knot-like Motifs

    A four-helix bundle is a well-characterized motif often used as a target for designed pharmaceutical therapeutics and nutritional supplements. Recently, we discovered a new structural complexity within this motif created by a disulphide bridge in the long-chain helical bundle cytokine leptin. When oxidized, leptin contains a disulphide bridge creating a covalent-loop through which part of the polypeptide chain is threaded (as seen in knotted proteins). We explored whether other proteins contain a similar intriguing knot-like structure as in leptin and discovered 11 structurally homologous proteins in the PDB. We call this new helical family class the Pierced Lasso Bundle (PLB) and the knot-like threaded structural motif a Pierced Lasso (PL). In the current study, we use structure-based simulation to investigate the threading/folding mechanisms for all the PLBs along with three unthreaded homologs as the covalent loop (or lasso) in leptin is important in folding dynamics and activity. We find that the presence of a small covalent loop leads to a mechanism where structural elements slipknot to thread through the covalent loop. Larger loops use a piercing mechanism where the free terminal plugs through the covalent loop. Remarkably, the position of the loop as well as its size influences the native state dynamics, which can impact receptor binding and biological activity. This previously unrecognized complexity of knot-like proteins within the helical bundle family comprises a completely new class within the knot family, and the hidden complexity we unraveled in the PLBs is expected to be found in other protein structures outside the four-helix bundles. The insights gained here provide critical new elements for future investigation of this emerging class of proteins, where function and the energetic landscape can be controlled by hidden topology, and should be take into account in ab initio predictions of newly identified protein targets.

    Background: Individuals with high-level spinal cord injuries need effective ways to perform activities. Objectives: To develop and test a medically supervised tongue-piercing protocol and the wearing of a magnet-containing tongue barbell for use with the Tongue Drive System (TDS) in persons with tetraplegia. Methods: Volunteers with tetraplegia underwent initial screening sessions using a magnet glued on the tongue to activate and use the TDS. This was followed by tongue piercing, insertion of a standard barbell, a 4-week healing period, and an exchange of the standard barbell for a magnet-containing barbell. This was then used twice weekly for 6 to 8 weeks to perform computer tasks, drive a powered wheelchair, accomplish in-chair weight shifts, and dial a phone. Symptoms of intraoral dysfunction, change in tongue size following piercing, and subjective assessment of receiving and wearing a magnet-containing tongue barbell and its usability with the TDS were evaluated. Results: Twenty-one volunteers underwent initial trial sessions. Thirteen had their tongues pierced. One individual’s barbell dislodged during healing resulting in tongue-tract closure. Twelve had the barbell exchanged for a magnet-containing barbell. One subject withdrew for unrelated issues. Eleven completed the TDS testing sessions and were able to complete the assigned tasks. No serious adverse events occurred related to wearing or using a tongue barbell to operate the TDS. Conclusions: Using careful selection criteria and a medically supervised piercing protocol, no excess risk was associated with tongue piercing and wearing a tongue barbell in people with tetraplegia. Participants were able to operate the TDS. PMID:25762861

  4. Ventilation Inception and Washout, Scaling, and Effects on Hydrodynamic Performance of a Surface Piercing Strut

    2014-11-01

    High-lift devices that operate at or near a fluid free surface (such as surface-piercing or shallowly-submerged propellers and hydrofoils) are prone to a multiphase flow phenomenon called ventilation, wherein non-condensable gas is entrained in the low-pressure flow, forming a cavity around the body and dramatically altering the global hydrodynamic forces. Experiments are being conducted at the University of Michigan's towing tank using a canonical surface-piercing strut to investigate atmospheric ventilation. The goals of the work are (i) to gain an understanding of the dominant physics in fully wetted, partially ventilated, and fully ventilated flow regimes, (ii) to quantify the effects of governing dimensionless parameters on the transition between flow regimes, and (iii) to develop scaling relations for the transition between flow regimes. Using theoretical arguments and flow visualization techniques, new criteria are developed for classifying flow regimes and transition mechanisms. Unsteady transition mechanisms are described and mapped as functions of the governing non-dimensional parameters. A theoretical scaling relationship is developed for ventilation washout, which is shown to adequately capture the experimentally-observed washout boundary. This material is based upon work supported by the National Science Foundation Graduate Student Research Fellowship under Grant No. DGE 1256260. Support also comes from the Naval Engineering Education Center (Award No. N65540-10-C-003).

  5. Water Surface Ripples Generated by the Turbulent Boundary Layer of a Surface-Piercing Moving Wall

    Free surface ripples created by subsurface turbulence along a surface-piercing moving wall are studied experimentally. In this experiment, a meter-wide stainless steel belt travels horizontally in a loop around two rollers with vertically oriented axes, which are separated by 7.5 meters. One of the two 7.5-m-long belt sections between the rollers is in contact with the water in a large open-surface water tank and the water level is adjusted so that the top of the belt pierces the water free surface. The belt is launched from rest with a 3 g acceleration in order to quickly reach a steady state velocity. This belt motion creates a temporally evolving boundary layer analogous to the spatially evolving boundary layer created along the side of a ship hull moving at the belt velocity, with a length equivalent to the length of belt that has passed the measurement region. The water surface ripples generated by the subsurface turbulence are measured in a plane normal to the belt using a cinematic LIF technique. It is found that the overall RMS surface fluctuations increase linearly with belt speed and that the spatial distributions of the fluctuations show a sharp increase near the wall. The support of the Office of Naval Research is gratefully acknowledged.

    Pierce's disease, caused by the bacterium Xylella fastidiosa, is one of the most devastating diseases of cultivated grape, currently restricted to the Americas. To test the long-standing hypothesis that Pierce's disease results from pathogen-induced drought stress, we used the Affymetrix Vitis GeneChip to compare the transcriptional response of Vitis vinifera to Xylella infection, water deficit, or a combination of the two stresses. The results reveal a redirection of gene transcription involving 822 genes with a minimum twofold change (P < 0.05), including the upregulation of transcripts for phenylpropanoid and flavonoid biosynthesis, pathogenesis-related proteins, abscisic acid- and jasmonic acid-responsive biosynthesis, and downregulation of transcripts related to photosynthesis, growth, and nutrition. Although the transcriptional response of plants to Xylella infection was largely distinct from the response of healthy plants to water stress, we find that 138 of the pathogen-induced genes exhibited a significantly stronger transcriptional response when plants were simultaneously exposed to infection and drought stress, suggesting a strong interaction between disease and water deficit. This interaction between drought stress and disease was mirrored in planta at the physiological level for aspects of water relations and photosynthesis and in terms of the severity of disease symptoms and the extent of pathogen colonization, providing a molecular correlate of the classical concept of the disease triangle in which environment impacts disease severity.

    Chronic upper gastrointestinal (GI) symptoms of unclear etiology are frustrating to patients and physicians alike. The integrative medicine procedures of acupuncture and neural therapy may provide treatment options. Tongue piercing, which is prevalent in 5.6% of the adolescent population, may be a contributing factor in upper gastrointestinal symptoms. The objectives of the study were as follows: (1) To demonstrate the usefulness of an integrative medicine treatment approach in two cases of patients with chronic abdominal pain, nausea, and vomiting of unclear etiology who had failed standard medical management. (2) To identify scars from tongue piercings as a possible contributing factor in chronic upper GI symptoms of unclear etiology. Two retrospective case studies are presented of young adult females who were seen in a private multi-physician integrative medicine practice in the US. The patients were treated with neural therapy and acupuncture. The desired outcome was the cessation or reduction of the frequency of abdominal pain, nausea, and vomiting. Both patients had resolution of their symptoms. From this study, we have concluded the following: (1) Tongue scars from tongue rings may be causes of chronic upper gastrointestinal symptoms.

    This final report summarizes the design and performance of the VUW-8028 Pierce-Wiggler electron beam systems, which can be used to power high frequency gyro-BWO's. The operator's manual for this gyro-BWO beamstick is included as appendix A. Researchers at Lawrence Livermore National Laboratory (LLNL) are developing a gyro-BWO with a center frequency of 250 GHz, 6% bandwidth, and 10 kV peak output power. The gyro-BWO will be used to drive a free electron laser amplifier at LLNL. The electron beam requirements of the gyro-BWO application are: Small beam size, .100 inch at 2500 gauss axial magnetic field; a large fraction of the electron energy in rotational velocity; ability to vary the electrons' axial velocity easily, for electronic tuning; and low velocity spread i.e. little variation in the axial velocities of the electrons in the interaction region. 1 ref., 13 figs.

    Data from 15 jewellery students, in their 1st and 3rd years of training, were analysed to show how data collected from work settings can be used to objectively evaluate performance in the use of tools. Participants were asked to use a piercing saw to cut 5 lines in a piece of metal. Performance was categorised in terms of functional dynamics. Data from strain gauges and a tri-axial accelerometer (built into the handle of the saw) were recorded and thirteen metrics derived from these data. The key question for this paper is which metrics could be used to distinguish levels of ability. Principal Components Analysis identified five components: sawing action; grasp of handle; task completion time; lateral deviation of strokes; and quality of lines cut. Using representative metrics for these components, participants could be ranked in terms of performance (low, medium, high) and statistical analysis showed significant differences between participants on key metrics.

    Because of their unique physical, chemical, and electrical properties, carbon nanotubes are an attractive material for many potential applications. Their interactions with biological entities are, however, not yet completely understood. To fill this knowledge gap, we present experimental results for aqueous systems containing single-walled carbon nanotubes and phospholipid membranes, prepared in the form of liposomes. Our results suggest that dispersed single-walled carbon nanotubes, instead of piercing the liposome membranes, adsorb on them at low ionic strength. Transmission electron microscopy and dye-leakage experiments show that the liposomes remain for the most part intact in the presence of the nanotubes. Further, the liposomes are found to stabilize carbon nanotube dispersions when the surfactant sodium dodecylbenezenesulfonate is present at low concentrations. Quantifying the interactions between carbon nanotubes and phospholipid membranes could not only shed light on potential nanotubes cytotoxicity but also open up new research venues for their use in controlled drug delivery and/or gene and cancer therapy.

    The equilibria bifurcations of the biparametric version of the classical Pierce diode, a one-dimensional plasma-filled device, are analyzed in detail. Our investigation reveals that this spatiotemporal model is not structurally stable in relation to a second control parameter, the ratio of the plasma ion density to the injected electron beam density. For the first time, we relate the existence of one-fluid chaotic regions with specific biparametric equilibria bifurcations, identifying the restricted regions in the parametric plane where they occur. We show that the system presents several biparametric scenarios involving codimension-two transcritical bifurcations. Finally, we provide the spatial profile of the stable and unstable one-fluid equilibria in order to describe their metamorphoses.

    Do women suffering from borderline symptomatology differ from women without these symptoms regarding their motives for body modifications?A sample of 289 women with body modifications were questioned about their tattoos, piercings and motives for body modifications as well as about symptoms of borderline personality disorder. Women with borderline symptomatology were compared to women without borderline symptomatology concerning the extent of and motives for body modification.The 2 groups showed no differences in regard to amount and extent of body modifications. The "borderline"-group considered individuality, coping and management of negative life-events to be more crucial reasons for body modification than the non-borderline females.The degree of a person's body modification is not a feasible indicator for psychopathological strain. Though, for people with borderline tendency body modification may serve as a coping strategy similar to self-injury.

    Washington State has some of the highest percentages of school immunization exemptions in the country. We compared school immunization records in a rural school district in Pierce County, Washington, to immunization records in the state immunization information system (IIS) and parent-held records. Correcting school immunization records resulted in an increase in the number of students classified as fully immunized from 1,189 to 1,564 (p < .0001). We conducted school-based immunization clinics that increased the number of fully immunized students to 1,624 (p = .013). Immunized students with certificates of exemption on file suggest exemptions of convenience. Strategies to improve school immunization services include assigning IIS access to school administrative staff and educating school staff and parents on the importance of immunization.

    Study of the mechanisms understanding how chemically functionalized carbon nanotubes internalize into mammalian cells is important in view of their design as new tools for therapeutic and diagnostic applications. The initial contact between the nanotube and the cell membrane allows elucidation of the types of interaction that are occurring and the contribution from the types of functional groups at the nanotube surface. Here we offer a combination of experimental and theoretical evidence of the initial phases of interaction between functionalized carbon nanotubes with model and cellular membranes. Both experimental and theoretical data reveal the critical parameters to determine direct translocation of the nanotubes through the membrane into the cytoplasm as a result of three distinct processes that can be summarized as landing, piercing and uptake.Study of the mechanisms understanding how chemically functionalized carbon nanotubes internalize into mammalian cells is important in view of their design as new tools for therapeutic and diagnostic applications.

  17. Simulation of the Groundwater-Flow System in Pierce, Polk, and St. Croix Counties, Wisconsin

    2009-01-01

    Groundwater is the sole source of residential water supply in Pierce, Polk, and St. Croix Counties, Wisconsin. A regional three-dimensional groundwater-flow model and three associated demonstration inset models were developed to simulate the groundwater-flow systems in the three-county area. The models were developed by the U.S. Geological Survey in cooperation with the three county governments. The objectives of the regional model of Pierce, Polk, and St. Croix Counties were to improve understanding of the groundwaterflow system and to develop a tool suitable for evaluating the effects of potential water-management programs. The regional groundwater-flow model described in this report simulates the major hydrogeologic features of the modeled area, including bedrock and surficial aquifers, groundwater/surface-water interactions, and groundwater withdrawals from high-capacity wells. Results from the regional model indicate that about 82 percent of groundwater in the three counties is from recharge within the counties; 15 percent is from surface-water sources, consisting primarily of recirculated groundwater seepage in areas with abrupt surface-water-level changes, such as near waterfalls, dams, and the downgradient side of reservoirs and lakes; and 4 percent is from inflow across the county boundaries. Groundwater flow out of the counties is to streams (85 percent), outflow across county boundaries (14 percent), and pumping wells (1 percent). These results demonstrate that the primary source of groundwater withdrawn by pumping wells is water that recharges within the counties and would otherwise discharge to local streams and lakes. Under current conditions, the St. Croix and Mississippi Rivers are groundwater discharge locations (gaining reaches) and appear to function as 'fully penetrating' hydraulic boundaries such that groundwater does not cross between Wisconsin and Minnesota beneath them. Being hydraulic boundaries, however, they can change in response to

    Foreign body (FB) aspiration is commonly seen in children but less commonly in adolescents. Headscarf pin aspiration is common in Muslim girls, who inappropriately place the pins between their lips while securing the scarf on the head. Bronchoscopy is the treatment modality of choice, and surgery is rarely required. An 11-year-old girl was admitted as a case of accidental aspiration of headscarf pin. X-ray chest showed a radiopaque object in the left bronchus piercing the lung parenchyma. Computed tomography (CT) chest confirmed the diagnosis. The headscarf pin was removed by flexible bronchoscopy as the ear, nose, and throat (ENT) surgeon failed to remove it by rigid bronchoscopy. The FB was removed successfully and the patient was discharged home. Removal of a sharp pin by bronchoscopy is difficult, especially if it pierces the lung parenchyma. In our case, the pin was bent by forceps and then removed by a flexible bronchoscope, which requires a highly skilled professional. PMID:27578937

    2007-05-01

    Geologic investigations in Honduras and Nicaragua reveal features and structures which correlate to southern Mexico in sufficient detail to constrain the latest Cretaceous position of the Chortis block along the truncated southwestern margin of Mexico. Two regional features common to southern Mexico and Honduras are 1) their Precambrian basement contain both containing Grenville age protoliths and 2) the similar Mesozoic cover of Late Cretaceous clastic, marine sandstone and shale over Early Cretaceous shallow water platform carbonate rocks. Three north trending piercing lines are common to southern Mexico and to the Chortis block: 1) north trending mid-Cretaceous arc and geochemical trends of Teloloapan arc in Mexico and the Manto arc in Honduras; 2) north trending late Cretaceous structural belts southern Mexico and the Frey Pedro, Comayagua, Minas de Oro and La Flor structural belts of Honduras and 3) a north trending common magnetic signature in Mexico separating the Guerrero terrane from the autochthonous terranes of Mexico and in Honduras forming the southwestern edge of the Precambrian continental basement. A forth piercing line is the east trending alignment of the eastern Honduras Colon fold belt with late Cretaceous east trending fold belt of southeastern Guatemala. Our best fit alignment of these features and piercing lines place the northern limit of the Chortis block along the southern margin of Mexico between Zihuatenejo and Acapulco in the latest Cretaceous and is consistent with 35 degrees of post-Cretaceous counterclockwise rotation of the Chortis block.

    Though the popularity of body modification increases, psychosocial data about practitioners of body piercing and tattooing are few and controversial. Most studies used semi-structured interviews and relatively small sample sizes. The aim of this study was to explore psychosocial background information (motivation, sexual abuse) for body modification practises based on a sufficiently large sample. A core group of 432 subjects with body piercings and/or tattoos (readers of a specialised magazine on body modification; mean age: 28 years) was investigated in this study using a 55-item questionnaire. The mean number of body modifications (piercings and tattoos) was nine. Participants with a history of sexual abuse and high users with more than 10 body modifications differed from those without these features with respect to several motivations and consequences of body modification. Participants with sexual abuse often stated that they wanted to overcome certain experiences, and high users were characterised by the feeling of an addiction to continue body modification. Clinicians should include questions on body modifications and their motives in anamnestic schedules.

    A vertical flexible, thin, cylindrical shell is considered to be clamped to a rigid base in shallow water and piercing its surface. The shell is composed of an isotropic and homogeneous material and may be empty inside or filled with compressible fluid. Linear acoustics and structural dynamics are used to model sound scattering caused by an external incident sound wave. A solution is derived using a Fourier transform in the tangential and vertical directions. A collocation technique coupled with an orthogonalization procedure is used to account for the edge conditions of the shell. It is shown that zero sound scattering, indicating acoustic invisibility, is theoretically attainable and can be achieved when a continuous distribution of an oscillating pressure load is applied on the shell's wall. Similarly, zero sound transmission into the shell's inner fluid can also be considered. The possibility of using a pre-determined discrete distribution of the applied pressure load is also discussed. The derived equations are numerically solved to examine sound scattering by a thin aluminium shell in shallow water. PMID:21690137

    In the present work, a recently developed solid state joining technique, Friction self-piercing riveting (F-SPR), has been applied for joining high strength aluminum alloy AA7075-T6 to magnesium alloy AZ31B. The process was performed on a specially designed machine where the spindle can achieve the motion of sudden stop. Effects of rivet rotating rate and punch speed on axial plunge force, torque, joint microstructure and quality have been analyzed systematically. During F-SPR, higher rotating rate and slower punch speed can reduce axial force and torque, which correspondingly results in a slightly smaller interlock between rivet leg and joined materials. Improved localmore » flowability of both aluminum and magnesium alloys under a higher rotating speed results in a thicker aluminum layer surrounding the rivet leg, where formation of Al-Mg intermetallics was observed. Equivalent joint strength obtained in this study are higher than the yield strength of the AZ31 Mg alloy. One of the tensile failure modes is the rivet fracture, which is due to local softening of rivet leg from frictional heat. Lastly, other two failure modes include rivet pullout and shear through of bottom sheet.« less

    The Tacoma landfill, located in western Pierce County, Washington, has been used for the disposal of waste since about 1960. Disposal operations are planned to continue at this site until at least 1990. Data were compiled and interpreted to help understand the possible effects of the landfill on water quality in the surrounding area. Data were collected from published and unpublished reports of the U.S. Geological Survey, and from predominantly unpublished data in the files of other government agencies. The Tacoma landfill is underlain by unconsolidated, glacially derived deposits that consist of a wide variety of mixtures of clay to boulder-sized materials. Ground water is mostly the result of rainfall on the land surface, and moves through artesian aquifers (under the landfill) that are tapped for both domestic and municipal use. Hazardous liquid and dissolved wastes are probably present in the landfill, and potential flow paths for waste migration exist. An undetermined number of single-family domestic wells and 18 public-supply wells are within 3 miles of the landfill, three as close as 0.2 miles. There is only limited evidence indicating ground- and surface-water contamination. Further investigations of the geology, hydrology and water quality are needed to characterize the impact the landfill has on ground- and surface-water of the surrounding area. (USGS)

    Depleted uranium (DU) from the military testing and use of armor-piercing kinetic energy penetrators has been shown to accumulate in soils; however, little is known about the toxicity of DU geochemical species created through corrosion or weathering. The purpose of the present study was to assess the toxic effects and bioaccumulation potential of field-collected DU oxides to the model terrestrial invertebrates Eisenia fetida (earthworm) and Porcellio scaber (isopod). Earthworm studies were acute (72 h) dermal exposures or 28-d spiked soil exposures that used noncontaminated field-collected soils from the US Army's Yuma and Aberdeen Proving Grounds. Endpoints assessed in earthworm testing included bioaccumulation, growth, reproduction, behavior (soil avoidance), and cellular stress (neutral red uptake in coelomocytes). Isopod testing used spiked food, and endpoints assessed included bioaccumulation, survival, and feeding behavior. Concentration-dependent bioaccumulation of DU in earthworms was observed with a maximum bioaccumulation factor of 0.35; however, no significant reductions in survival or impacts to cellular stress were observed. Reproduction lowest-observed-effect concentrations (LOEC) of 158 mg/kg and 96 mg/kg were observed in Yuma Proving Ground and a Mississippi reference soil (Karnac Ferry), respectively. Earthworm avoidance of contaminated soils was not observed in 48-h soil avoidance studies; however, isopods were shown to avoid food spiked with 12.7% by weight DU oxides through digital tracking studies.

    In this study, the tensile and fatigue behaviour of self-piercing rivets (SPRs) in carbon fibre reinforced plastic (CFRP) to aluminium 6111 T82 alloys were evaluated. An average maximum lap-shear tensile load capacity of 3858 N was achieved, which is comparable to metal-to-metal SPR lap-shear joints. The CFRP-Al SPRs failed in lap-shear tension due to pull-out of the rivet head from the CFRP upper sheet. The CFRP-Al SPR lap- shear specimens exhibited superior fatigue life compared to previously studied aluminium-to- aluminium SPR lap-shear joints. The SPR lap-shear joints under fatigue loads failed predominantly due to kinked crack growth along the width of the bottom aluminium sheet. The fatigue cracks initiated in the plastically deformed region of the aluminium sheet close to the rivet shank in the rivet-sheet interlock region. Scatter in fatigue life and failure modes was observed in SPR lap-shear specimens tested close to maximum tensile load.

    The external starshade is a method for the direct detection and spectral characterization of terrestrial planets around other stars, a key goal identified in ASTRO2010. Tests of this approach have been and continue to be conducted in the lab and in the field (Samuele et al., 2010, Glassman et al., 2014) using non-collimated light sources with a spherical wavefront. We extend the current approach to performing night-time observations of astronomical objects using small-scale (approximately 1/300th) starshades and the McMath-Pierce Solar Telescope at Kitt Peak National Observatory. We placed a starshade directly in the path of the beam from an astronomical object in front of the main heliostat. Using only flat mirrors, we then directed the light through the observatory path and reflected it off the West heliostat to an external telescope located approximately 270m away, for an effective baseline of 420m.This configuration allowed us to make measurements of flat wavefront sources with a Fresnel number close to those expected in proposed full-scale space configurations. We present the results of our engineering runs conducted in 2015.

    Pierce's disease (PD) caused by Xylella fastidiosa prevents cultivation of grapevine (Vitis vinifera) and susceptible hybrids in the southeastern United States and poses a major threat to the grape industry of California and Texas. Genetic resistance is the only proven control of X. fastidiosa. Genetic engineering offers an alternative to heretofore ineffective conventional breeding in order to transfer only PD resistance traits into elite cultivars. A synthetic gene encoding lytic peptide LIMA-A was introduced into V. vinifera and a Vitis hybrid to assess in planta inhibition of X. fastidiosa. Over 1050 independent transgenic plant lines were evaluated in the greenhouse, among which nine lines were selected and tested under naturally-inoculated field conditions. These selected plant lines in the greenhouse remain disease-free for 10 years, to date, even with multiple manual pathogen inoculations. However, all these lines in the field, including a grafted transgenic rootstock, succumbed to PD within 7 years. We conclude that in planta production of antimicrobial lytic peptides does not provide durable PD resistance to grapevine under field conditions. PMID:25894660

    This paper presents a new approach, in applying the Pierce two-node model, to predict local skin temperatures of individual body parts with good accuracy. In this study, local skin temperature measurements at 24 sites on the bodies of 11 human subjects were carried out in a controlled environment under three different indoor conditions (i.e. neutral, warm and cold). The neutral condition measurements were used to adjust the local skin set-points in the model for each body part. Additional modifications to the calculation algorithm were introduced corresponding to different body parts. The local core set-points were then calculated, using a line search method, as the input values that allow the model to predict the skin temperatures with maximum deviation of ±0.1°C for the neutral condition. The model predictability was verified for the other two indoor conditions, and the results show that the modified model predicts local skin temperatures with average deviation of ±0.3°C.

    2015-01-28

    Experimental observations are presented of a single surface-piercing column subject to a wide range of surface gravity waves. With the column diameter, D, chosen such that the flow lies within the drag-inertia regime, two types of high-frequency wave scattering are identified. The first is driven by the run-up and wash-down on the surface of the column in the vicinity of the upstream and downstream stagnation points. The second concerns the circulation of fluid around the column, leading to the scattering of a pair of non-concentric wavefronts. The phasing of the wave cycle at which this second mode evolves is dependent upon the time taken for fluid to move around the column. This introduces an additional time-scale, explaining why existing diffraction solutions, based upon a harmonic analysis of the incident waves, cannot describe this scattered component. The interaction between the scattered waves and the next (steep) incident wave can produce a large amplification of the scattered waves, particularly the second type. Evidence is provided to show that these interactions can produce highly localized free-surface effects, including vertical jetting, with important implications for the setting of deck elevations, the occurrence of wave slamming and the development of large run-up velocities.

  14. Surface-Piercing Activities of the Humpback Whale, Megaptera, Related to Parasites and Mechanics}

    2006-12-01

    Humpback whales leap out of the water (breach), strike the water surface with their long fins (flipper), strike the water surface with their tail (lobtail), and hold motionless in a vertical position with their heads above water (spyhop). These four surface-piercing activities were known to early whalers, but their explanations remain uncertain. A whale breaches by swimming from depth toward the water surface at an oblique angle, propelling himself into the air at an angle to the water's surface (0 to 70 degrees), rotating about his long axis, and landing on his back, belly up to the sky. Rotation requires applying angular momentum to the whale's trunk, which photographs suggest comes from flinging out the flipper on the side rotating upward, and keeping the downward-rotating flipper closer to the trunk. The humpback has unusually long flippers (long moment arms) up to 30 percent of trunk length. Its generic name, Megaptera, can translate as `long flipper'. Continued use of one flipper as the moment arm raises the possibility of right-handed or left-handed whales, but Whitehead's (1985) data do not support that result. Parasites as a cause of breaching is a hypothesis at least as old as Beale (1839), but in the last half of the 20th century, breaching, flippering, and lobtailing came to be understood as social activities of whales. Whitehead's work in the 1980s provides much data on humpback activities, as well as a prevailing social interpretation of the data. External parasites (loosely defined) include whale lice (fingernail-sized crablike animals) and barnacles (both fixed shell and flexible goosenecked species). Thousands of these animals may inhabit a single whale. Whale lice populate crevices of the jaws and eyes, the pleats in the throat pouch under the jaw, and shelter at fixed barnacles. Fixed barnacles thrive on exposed bumps on the whale's head and flippers. Gooseneck barnacles appear in photos attached to trailing edges of fins and tail. Some parasites

    The surface-water hydrology in Clear, Clarks, and Clover Creek Basins in central Pierce County, Washington, is described with a conceptual model of the runoff processes and then simulated with the Hydrological Simulation Program-FORTRAN (HSPF), a continuous, deterministic hydrologic model. The study area is currently undergoing a rapid conversion of rural, undeveloped land to urban and suburban land that often changes the flow characteristics of the streams that drain these lands. The complex interactions of land cover, climate, soils, topography, channel characteristics, and ground- water flow patterns determine the surface-water hydrology of the study area and require a complex numerical model to assess the impact of urbanization on streamflows. The U.S. Geological Survey completed this investigation in cooperation with the Storm Drainage and Surface Water Management Utility within the Pierce County Department of Public Works to describe the important rainfall-runoff processes within the study area and to develop a simulation model to be used as a tool to predict changes in runoff characteristics resulting from changes in land use. The conceptual model, a qualitative representation of the study basins, links the physical characteristics to the runoff process of the study basins. The model incorporates 11 generalizations identified by the investigation, eight of which describe runoff from hillslopes, and three that account for the effects of channel characteristics and ground-water flow patterns on runoff. Stream discharge was measured at 28 sites and precipitation was measured at six sites for 3 years in two overlapping phases during the period of October 1989 through September 1992 to calibrate and validate the simulation model. Comparison of rainfall data from October 1989 through September 1992 shows the data-collection period beginning with 2 wet water years followed by the relatively dry 1992 water year. Runoff was simulated with two basin models-the Clover

    In the present paper the influence of a higher setting velocity in the joining process of self piercing solid-rivets is shown. In the conventional process tool velocities well below 1 m/s are common. The present research results show the potential of increasing them in the range of about 5 m/s. The results are especially relevant for joining high-strength steels. These steel sheets often cause problems in the process of riveting mixed materials, e. g. aluminium-steel compound. The high strength of the steel sometimes leads to undesirable material flow in the joining process or unwanted burr development. These effects, which are described in detail in the article, can be reduced significantly for the investigated cases by the use of higher tool velocities. Using a high speed camera and a load cell, a test setup based on a drop tower was realized. It was used to time the force signals and the motion profile of the high speed riveting process. The results of the force analysis show an oscillating force progression. Within a numerical research the principal effects influencing the results of the riveting process can be shown. It was found that the pulse-like force transmission between riveting machine and punch, results in various vibrations especially of long and thin tool parts. Hence the rivet penetrates the sheet metal with non-uniform velocities. As a result the early indentation of die into the lower sheet metal at the beginning of the process is reduced, so that the final process step provides a sufficient material flow into the circular rivet groove. A strain-rate dependent process model with elastic tool properties and consideration of inertia effects is presented.

    Xylella fastidiosa (X. fastidiosa) infects a wide range of plant hosts and causes economically serious diseases, including Pierce's Disease (PD) of grapevines. X. fastidiosa biocontrol strain EB92-1 was isolated from elderberry and is infectious and persistent in grapevines but causes only very slight symptoms under ideal conditions. The draft genome of EB92-1 revealed that it appeared to be missing genes encoding 10 potential PD pathogenicity effectors found in Temecula1. Subsequent PCR and sequencing analyses confirmed that EB92-1 was missing the following predicted effectors found in Temecula1: two type II secreted enzymes, including a lipase (LipA; PD1703) and a serine protease (PD0956); two identical genes encoding proteins similar to Zonula occludens toxins (Zot; PD0915 and PD0928), and at least one relatively short, hemagglutinin-like protein (PD0986). Leaves of tobacco and citrus inoculated with cell-free, crude protein extracts of E. coli BL21(DE3) overexpressing PD1703 exhibited a hypersensitive response (HR) in less than 24 hours. When cloned into shuttle vector pBBR1MCS-5, PD1703 conferred strong secreted lipase activity to Xanthomonas citri, E. coli and X. fastidiosa EB92-1 in plate assays. EB92-1/PD1703 transformants also showed significantly increased disease symptoms on grapevines, characteristic of PD. Genes predicted to encode PD0928 (Zot) and a PD0986 (hemagglutinin) were also cloned into pBBR1MCS-5 and moved into EB92-1; both transformants also showed significantly increased symptoms on V. vinifera vines, characteristic of PD. Together, these results reveal that PD effectors include at least a lipase, two Zot-like toxins and a possibly redundant hemagglutinin, none of which are necessary for parasitic survival of X. fastidiosa populations in grapevines or elderberry.

    Hydroxysteroid (17beta) dehydrogenase 10 (HSD10) is a mitochondrial multifunctional enzyme encoded by the HSD17B10 gene. Missense mutations in this gene result in HSD10 deficiency, whereas a silent mutation results in mental retardation, X-linked, syndromic 10 (MRXS10). Here we report a novel missense mutation found in the HSD17B10 gene, namely c.194T>C transition (rs104886492), brought about by the loss of two forked methyl groups of valine 65 in the HSD10 active site. The affected boy, who possesses mutant HSD10 (p.V65A), has a neurological syndrome with metabolic derangements, choreoathetosis, refractory epilepsy and learning disability. He has no history of acute decompensation or metabolic acidosis whereas his urine organic acid profile, showing elevated levels of 2-methyl-3-hydroxybutyrate and tiglylglycine, is characteristic of HSD10 deficiency. His HSD10 activity was much lower than the normal control level, with normal β-ketothiolase activity. The c.194T>C mutation in HSD17B10 can be identified by the restriction fragment polymorphism analysis, thereby facilitating the screening of this novel mutation in individuals with intellectual disability of unknown etiology and their family members much easier. The patient's mother is an asymptomatic carrier, and has a mixed ancestry (Hawaiian, Japanese and Chinese). This demonstrates that HSD10 deficiency patients are not confined to a particular ethnicity although previously reported cases were either Spanish or German descendants.

    For a significant number of patients, there exists no, or only little, interest in developing a treatment for their disease or condition. Especially with regard to rare diseases, the lack of commercial interest in drug development is a burning issue. Several interventions have been made in the regulatory field in order to address the commercial disinterest in these conditions. However, existing regulations mainly focus on the provision of incentives to the sponsors of clinical trials of orphan drugs, and leave unanswered the overarching question about the rightful place of orphan drugs in resource allocation systems. In this article, we analyse the ethical aspects of funding research and development in the field of rare diseases. We then propose an ethical framework that can help health policy makers move forward in the difficult matter of fairly allocating resources for the prevention, diagnosis and treatment of rare diseases.

    Objective To examine the differences in dietary intakes of children consuming school meals and packed lunches, the contribution of lunchtime intake to overall dietary intake and how lunchtime intake relates to current food-based recommendations for school meals. Design Cross-sectional analysis of overall intake of macronutrients and food choice from 4-day food diaries and school lunchtime intake from the two diary days completed while at school. Setting Norfolk, UK Subjects One thousand six hundred and twenty six children (aged 9-10 years) attending 90 Norfolk primary schools Results At school lunchtime school meal eaters consumed more vegetables, sweet snacks, chips, starchy foods, and milk, and less squash/cordial, fruit, bread, confectionery and savoury snacks than packed lunch eaters. These differences were also reflected in the overall diet. On average school meal eaters met School Food Trust (SFT) food-based standards, while food choices among packed lunch eaters were less healthy. The contribution of food consumed at school lunchtime to overall diet varied by food and lunch type, ranging from 0.8% (milk intake in packed lunches) to 74.4% (savoury snack intake in packed lunches). Conclusions There were significant differences in the foods consumed by school meal and packed lunch eaters, with food choices among school meal eaters generally in line with SFT standards. The food choices made at school lunchtime make a significant contribution to overall diet. PMID:21936970

    Energy balance is regulated by a multifaceted system of physiological signals that influence energy intake and expenditure. Therefore, variability in the brain's response to food may be partially explained by differences in levels of metabolically active tissues throughout the body, including fat-free mass (FFM) and fat mass (FM). The purpose of this study was to test the hypothesis that children's body composition would be related to their brain response to food images varying in energy density (ED), a measure of energy content per weight of food. Functional magnetic resonance imaging (fMRI) was used to measure brain response to High (>1.5kcal/g) and Low (<1.5kcal/g) ED food images, and Control images, in 36 children ages 7-10years. Body composition was measured using bioelectrical impedance analysis. Multi-subject random effects general linear model (GLM) and two-factor repeated measures analysis of variance (ANOVA) were used to test for main effects of ED (High ED vs. Low ED) in a priori defined brain regions of interest previously implicated in energy homeostasis and reward processing. Pearson's correlations were then calculated between activation in these regions for various contrasts (High ED-Low ED, High ED-Control, Low ED-Control) and child body composition (FFM index, FM index, % body fat). Relative to Low ED foods, High ED foods elicited greater BOLD activation in the left thalamus. In the right substantia nigra, BOLD activation for the contrast of High ED-Low ED foods was positively associated with child FFM. There were no significant results for the High ED-Control or Low ED-Control contrasts. Our findings support literature on FFM as an appetitive driver, such that greater amounts of lean mass were associated with greater activation for High ED foods in an area of the brain associated with dopamine signaling and reward (substantia nigra). These results confirm our hypothesis that brain response to foods varying in energy content is related to measures of child body composition.

    The Aussie Optimism: Positive Thinking Skills Program (AOPTP) is a school-based prevention program aimed at addressing anxious and depressive symptoms in children aged 9–10 years. Nine-hundred and ten students from 22 Australian primary schools situated in low socio-economic areas were randomly assigned to either an intervention or control group, and assessed at a 30-month follow up. Those in the intervention group received the AOPTP program, where the control group continued to receive the regular health education course. Students completed self-report measures regarding their levels of depression, anxiety, and attribution style. Parents also reported on their children's externalizing and internalizing problems outside of school. There were no significant differences between groups in regard to anxiety or depression, as well as no significant differences in attributional styles. Parents reported significantly less hyperactive behaviors from children in the intervention group. This finding suggests that AOP-PTS has the capacity to treat externalizing problems at a medium term effect. The decrease in the externalizing problems provides evidence of a partial medium term intervention effect. Future studies should continue to evaluate the program at a long term follow up.

    Negative associations between bone turnover markers and bone mineral density have been reported. In order to study the association between ambient air pollution and bone turnover markers, as indicators of bone loss, we investigated associations between land-use regression modeled air pollution (NO2, PM2.5 mass, PM2.5 - 10 [coarse particles], PM10 mass and PM2.5 absorbance) and bone turnover markers in 2264 children aged 10 years. Serum osteocalcin and C-terminal telopeptide of type I collagen (CTx), measured by Modular-System (Roche), were the two bone turnover markers considered in this analysis. In total population, NO2, PM2.5 - 10 and PM10 mass exposure were positively and significantly associated with both osteocalcin and CTx. A 2.5 (95% CI: 0.6, 4.4) ng/ml increase in osteocalcin and a 24.0 (95% CI: 6.7, 41.3) ng/L increase in CTx were observed per IQR (6.7μg/m(3)) increase in NO2, independent of socioeconomic status, sex, age, pubertal status, fasting status and total physical activity. The estimated coefficients were 3.0 (95% CI: 0.1, 5.8) for osteocalcin and 32.3 (95% CI: 6.1, 58.5) for CTx with PM2.5 - 10; 3.2 (95% CI: 0.0, 6.4) for osteocalcin and 30.7 (95% CI: 1.7, 59.7) for CTx with PM10. Children living close to a major road (≤ 350m) had higher levels of both osteocalcin (1.4 [-1.2, 4.0] ng/ml) and CTx (16.2 [-7.4, 39.8] ng/L). The adverse impact of ambient air pollution on bone turnover rates observed in one of the study areas showed stimulation of more such studies.

    A high residential altitude impacts on the growth of children, and it has been suggested that linear growth (height) is more affected than body mass. The aim of the present study was to estimate the prevalence of obesity, overweight, underweight, and stunting in groups of native Tibetan children living at different residential altitudes (3700 vs 4300 m above sea level) and across ancestry (native Tibetan vs Han Chinese children living at the same altitude of 3700 m), as well as to examine the total effect of residential altitude and ancestry with stunting.Two cross-sectional studies of 1207 school children aged 9 to 10 years were conducted in Lhasa in 2005 and Tingri in 2007. Conventional age- and sex-specific cutoff values were used for defining underweight, normal weight, overweight, or obesity, whereas stunting was defined from sex-specific height-for-age z-scores (≤-2.0).The prevalence of underweight was high at 36.7% among Tingri Tibetan girls and 31.1% in Tingri Tibetan boys. The prevalence was statistically significant lower in Lhasa Tibetan girls (20.2%) than in both Tingri Tibetan girls and Han Chinese girls (33.7%), with a similar trend seen among boys. Severe and moderate stunting were found in 14.6% and 35.7%, respectively, of Tingri children, and near null among Han Chinese and native Tibetans in Lhasa. In logistic regression analyses, socioeconomic status and diet did not substantially change the observed crude association (total effect) (odds ratio [OR] = 3.3; 95% confidence interval [CI] 1.1-10.3) between ancestry and stunting. Similarly, adjustment for diet did not alter the crude association (direct effect) (OR = 101.3; 95% CI 37.1-276.4) between residential altitude and stunting.The prevalence estimates of stunting and underweight were high, and clearly higher among native Tibetan children living at a higher residential altitude (Tingri) than the lower residential altitude (Lhasa), in addition to being higher among Han Chinese children than Tibetan children living at the same residential altitude (Lhasa). Thus, physical growth according to age, in terms of both height and weight, affected children living at an altitude of 4300 m above sea level. PMID:26496254

    Musical training has been shown to positively influence linguistic abilities. To follow the developmental dynamics of this transfer effect at the preattentive level, we conducted a longitudinal study over 2 school years with nonmusician children randomly assigned to music or to painting training. We recorded the mismatch negativity (MMN), a cortical correlate of preattentive mismatch detection, to syllables that differed in vowel frequency, vowel duration, and voice onset time (VOT), using a test-training-retest procedure and 3 times of testing: before training, after 6 months and after 12 months of training. While no between-group differences were found before training, enhanced preattentive processing of syllabic duration and VOT, as reflected by greater MMN amplitude, but not of frequency, was found after 12 months of training in the music group only. These results demonstrate neuroplasticity in the child brain and suggest that active musical training rather than innate predispositions for music yielded the improvements in musically trained children. These results also highlight the influence of musical training for duration perception in speech and for the development of phonological representations in normally developing children. They support the importance of music-based training programs for children's education and open new remediation strategies for children with language-based learning impairments.

    Cognitive models of drawing are mainly based on assessment of copying performance of adults, whereas only a few studies have verified these models in young children. Moreover, developmental investigations have only rarely performed a systematic examination of the contribution of perceptual and representational visuo-spatial processes to copying and drawing from memory. In this study we investigated the role of visual perception and mental representation in both copying and drawing from memory skills in a sample of 227 typically developing children (53% females) aged 7-10 years. Participants underwent a neuropsychological assessment and the Rey-Osterrieth Complex Figure (ROCF). The fit and invariance of the predictive model considering visuo-spatial abilities, working memory, and executive functions were tested by means of hierarchical regressions and path analysis. Results showed that, in a gender invariant way, visual perception abilities and spatial mental representation had a direct effect on copying performance, whereas copying performance was the only specific predictor for drawing from memory. These effects were independent from age and socioeconomic status, and showed that cognitive models of drawing built up for adults could be considered for predicting copying and drawing from memory in children.

    The rising prevalence of childhood obesity is a key public health issue worldwide. Increased eating frequency (EF) is one aspect of diet that has been beneficially associated with obesity, although the mechanisms are unclear. The aims of the current study were to determine whether increased EF was associated with improved adiposity in children, and if this was due to differences in dietary and activity behaviors. Cross-sectional data from 1,700 children aged 9-10 year were analyzed to examine the associations between EF, as estimated from diet diaries, measures of adiposity, and activity measured by accelerometer. Analyses were stratified by obesity status using waist-to-height ratio to define obesity as it has been shown to be a good predictor of adverse health outcomes. Mean EF was 4.3 occasions/day and after adjustment for underreporting, energy intake (EI), and activity significant relative mean differences of -2.4% for body weight (P = 0.001), -1.0% for BMI (P = 0.020), -33% for BMI z-score (P = 0.014), and -0.6% for waist circumference (P = 0.031) per increase in eating occasion were found in healthy-weight but not centrally obese children. Differences between the extreme quartiles of EF were observed for total fat intake at breakfast (-18%, P < 0.001), fruit and vegetables from snacks (201% healthy-weight and 209% centrally obese children, P < 0.01), and for healthy-weight children, vigorous activity (4%, P = 0.003). Increased EF was favorably associated with adiposity, diet quality, and activity behaviors in healthy-weight but not centrally obese children. Future obesity interventions should consider the mediating role of diet quality and activity in the relationship between EF and adiposity in children.

    Tatoos and piercing, though they might appear as something like a trend, if not a craze, remain for a majority minority and even fringe practices. For the adolescent, questing for his identity (no more a child, not yet an adult), the tegmental sign is a way of engraving in the flesh dramatic events of his existence. The body mark is a search for independence, a symbolic attainment of self-reliance, a way of severing the umbilical cord and of asserting oneself. In face of a life no longer under control, the body is an object at hand, on which self-will is almost unbridled... These body modifications testify to change. PMID:16414301

    Polyurethane foam (PUF) mini-column was used to eliminate copper and iron for the determination of nickel in pierced rings. The PUF mini-column was connected to FIA system for on-line sorption of copper and iron in complexes form of CuSCN(+) and FeSCN(2+). For this season, the acid solution containing a mixture of Ni(II), Fe(III), Cu(II) and SCN(-) ions was firstly flew into the PUF column. Then, the percolated solution which Fe(III) and Cu(II) ions is separated from analysis was injected into FIA system to react with 4-(2-pyridylazo) resorcinol (PAR) reagent in basic condition which this method is called pH gradient technique. The Ni-PAR complexes obtained were measured theirs absorbance at 500 nm by UV visible spectrophotometer. In this study, it was found that Cu(II) and Fe(III) were completely to form complexes with 400 mmol/L KSCN and entirely to eliminate in acidic condition at pH 3.0. In the optimum condition of these experiments, the method provided the linear relationship between absorbance and the concentration of Ni(II) in the range from 5.00 to 30.00 mg/L. Linear equation is y=0.0134x+0.0033 (R(2)=0.9948). Precision, assessed in the term of the relative standard deviation, RSD, and accuracy for multiple determinations obtained in values of 0.77-1.73% and 97.4%, respectively. The level of an average amount of Ni(II) in six piercing rings was evaluated to be 14.78 mg/g.

    Microneedle (MN) is a relatively recent invention and an efficient technology for transdermal drug delivery (TDD). Conventionally, mathematical models of MNs drug delivery define the shape of the holes created by the MNs in the skin as the same as their actual geometry. Furthermore, the size of the MN holes in the skin is considered to be either the same or a certain fraction of the length of the MNs. However, the histological images of the MN-treated skin indicate that the real insertion depth is much shorter than the length of the MNs and the shapes may vary significantly from one case to another. In addressing these points, we propose a new approach for modeling MN-based drug delivery, which incorporates the histology of MN-pierced skin using a number of concepts borrowed from image processing tools. It is expected that the developed approach will provide better accuracy of the drug diffusion profile. A new computer program is developed to automatically obtain the outline of the MNs-treated holes and import these images into computer software for simulation of drug diffusion from MN systems. This method can provide a simple and fast way to test the quality of MNs design and modeling, as well as simulate experimental studies, for example, permeation experiments on MN-pierced skin using diffusion cell. The developed methodology is demonstrated using two-dimensional (2D) numerical modeling of flat MNs (2D). However, the methodology is general and can be implemented for three dimensional (3D) MNs if there is sufficient number of images for reconstructing a 3D image for numerical simulation. Numerical modeling for 3D geometry is demonstrated by using images of an ideal 3D MN. The methodology is not demonstrated for real 3D MNs, as there are not sufficient numbers of images for the purpose of this paper.

    Seabird population counts on the Pribilof Islands during summer 1984 were lower than counts made in 1976 or 1982, and usually much lower than in 1976. Estimates of black-legged kittiwake productivity were very low in 1984 on St. George and St. Paul islands and at Cape Pierce. The study also proposes a strategy for monitoring regional trends in seabird populations, productivity, and feeding habits, and detecting effects from oil and gas industry activities.

    Turbulent fluctuations in the vicinity of the water free surface along a flat, vertically oriented surface-piercing plate are studied experimentally using a laboratory-scale experiment. In this experiment, a meter-wide stainless steel belt travels horizontally in a loop around two rollers with vertically oriented axes, which are separated by 7.5 meters. This belt device is mounted inside a large water tank with the water level set just below the top edge of the belt. The belt, rollers, and supporting frame are contained within a sheet metal box to keep the device dry except for one 6-meter-long straight test section between rollers. The belt is launched from rest with a 3- g acceleration in order to quickly reach steady state velocity. This creates a temporally evolving boundary layer analogous to the spatially evolving boundary layer created along a flat-sided ship moving at the same velocity, with a length equivalent to the length of belt that has passed the measurement region since the belt motion began. Cinematic Stereo PIV measurements are performed in planes parallel to the free surface by imaging the flow from underneath the tank in order to study the modification of the boundary layer flow field due to the effects of the water free surface.

    Xylella fastidiosa is a xylem-limited bacterium in plant hosts and causes Pierce's disease (PD) of grapevines, which differ in susceptibility according to the Vitis species (spp.). In this work we compared X. fastidiosa biofilm formation and population dynamics when cultured in xylem saps from PD-susceptible and -resistant Vitis spp. under different conditions. Behaviors in a closed-culture system were compared to those in different sap-renewal cultures that would more closely mimic the physicochemical environment encountered in planta. Significant differences in biofilm formation and growth in saps from PD-susceptible and -resistant spp. were only observed using sap renewal culture. Compared to saps from susceptible V. vinifera, those from PD-resistant V. aestivalis supported lower titers of X. fastidiosa and less biofilm and V. champinii suppressed both growth and biofilm formation, behaviors which are correlated with disease susceptibility. Furthermore, in microfluidic chambers X. fastidiosa formed thick mature biofilm with three-dimensional (3-D) structures, such as pillars and mounds, in saps from all susceptible spp. In contrast, only small aggregates of various shapes were formed in saps from four out of five of the resistant spp.; sap from the resistant spp. V. mustangensis was an exception in that it also supported thick lawns of biofilm but not the above described 3-D structures typically seen in a mature biofilm from the susceptible saps. Our findings provide not only critical technical information for future bioassays, but also suggest further understanding of PD susceptibility.

    Fishing is a major local industry in Malaysia, particularly in rural areas. However, the rapidly increasing price of fuel is seriously affecting the industry's viability. At present, outboard petrol engines are the preferred choice for use in small-scale fishing boats because they deliver the advantages of high speed and low weight, they are easy to install, and they use minimal space. Petrol outboard engines are known to consume a greater amount of fuel than inboard diesel engines, but installing diesel engines with conventional submerged propellers in existing small-scale fishing boats is not economically viable because major hullform modifications and extra expenditure are required to achieve this. This study describes a proposal to enable reductions in fuel consumption by introducing the combined use of a diesel engine and surface-piercing propeller (SPP). An analysis of fuel consumption reduction is presented, together with an economic feasibility study. Resulting data reveal that the use of the proposed modifications would save 23.31 liters of fuel per trip (40.75 %) compared to outboard motors, equaling annual savings of RM 3962 per year.

    The host preference of the economically important fruit piercing moth, Calyptra lata (Butler 1881), was studied when exposed to different fruits and the odors of those fruits in enclosed feeding assays and in a two-choice olfactometer. The fruits consisted of three ripe and locally available types: raspberries, cherries and plums. Moths were released in cages with the ripened fruit and observed for any feeding events, which were then documented. Moths fed on both raspberries and cherries, but not on plums. To test the role of olfactory cues in fruit preference, male moths were released singly in the two choice olfactometer, with one type of fruit odor released in one arm and background control air in the other. The behavior of the moths was recorded on video. Parameters scored were 1) time to take off, 2) flight duration and 3) total time to source contact. The moths showed a significant preference for raspberry odor, exhibited a neutral response to cherry odor and significantly avoided the odor of plums. These results indicate that Calyptra lata demonstrates selective polyphagic feeding behavior and uses olfactory cues from both preferred and non-preferred fruits to detect and locate potential food sources. The possible implications for pest control are discussed. PMID:27324579

    A Brazilian isolate of Hibiscus latent Fort Pierce virus (HLFPV-BR) was firstly found in a hibiscus plant in Limeira, SP, Brazil. RACE PCR was carried out to obtain the full-length sequences of HLFPV-BR which is 6453 nucleotides and has more than 99.15 % of complete genomic RNA nucleotide sequence identity with that of HLFPV Japanese isolate. The genomic structure of HLFPV-BR is similar to other tobamoviruses. It includes a 5' untranslated region (UTR), followed by open reading frames encoding for a 128-kDa protein and a 188-kDa readthrough protein, a 38-kDa movement protein, 18-kDa coat protein, and a 3' UTR. Interestingly, the unique feature of poly(A) tract is also found within its 3'-UTR. Furthermore, from the total RNA extracted from the local lesions of HLFPV-BR-infected Chenopodium quinoa leaves, a biologically active, full-length cDNA clone encompassing the genome of HLFPV-BR was amplified and placed adjacent to a T7 RNA polymerase promoter. The capped in vitro transcripts from the cloned cDNA were infectious when mechanically inoculated into C. quinoa and Nicotiana benthamiana plants. This is the first report of the presence of an isolate of HLFPV in Brazil and the successful synthesis of a biologically active HLFPV-BR full-length cDNA clone. PMID:27139727

    Ethylene is a stress hormone with contrasting effects on herbivore resistance. However, it remains unknown whether these differences are plant- or herbivore-specific. We cloned a rice 1-aminocyclopropane-1-carboxylic acid (ACC) synthase gene, OsACS2, whose transcripts were rapidly up-regulated in response to mechanical wounding and infestation by two important pests: the striped stem borer (SSB) Chilo suppressalis and the brown planthopper (BPH) Nilaparvata lugens. Antisense expression of OsACS2 (as-acs) reduced elicited ethylene emission, SSB-elicited trypsin protease inhibitor (TrypPI) activity, SSB-induced volatile release, and SSB resistance. Exogenous application of ACC restored TrypPI activity and SSB resistance. In contrast to SSB, BPH infestation increased volatile emission in as-acs lines. Accordingly, BPH preferred to feed and oviposit on wild-type (WT) plants--an effect that could be attributed to two repellent volatiles, 2-heptanone and 2-heptanol, that were emitted in higher amounts by as-acs plants. BPH honeydew excretion was reduced and natural enemy attraction was enhanced in as-acs lines, resulting in higher overall resistance to BPH. These results demonstrate that ethylene signaling has contrasting, herbivore-specific effects on rice defense responses and resistance against a chewing and a piercing-sucking insect, and may mediate resistance trade-offs between herbivores of different feeding guilds in rice.

    Insect double-stranded (ds)RNA expression in transgenic crops can increase plant resistance to biotic stress; however, creating transgenic crops to defend against every insect pest is impractical. Arabidopsis Mob1A is required for organ growth and reproduction. When Arabidopsis roots were soaked in dsMob1A, the root lengths and numbers were significantly suppressed and plants could not bolt or flower. Twenty-four hours after rice roots were immersed in fluorescent-labelled dsEYFP (enhanced yellow fluorescent protein), fluorescence was observed in the rice sheath and stem and in planthoppers feeding on the rice. The expression levels of Ago and Dicer in rice and planthoppers were induced by dsEYFP. When rice roots were soaked in dsActin, their growth was also significantly suppressed. When planthoppers or Asian corn borers fed on rice or maize that had been irrigated with a solution containing the dsRNA of an insect target gene, the insect's mortality rate increased significantly. Our results demonstrate that dsRNAs can be absorbed by crop roots, trigger plant and insect RNAi and enhance piercing-sucking and stem-borer insect mortality rates. We also confirmed that dsRNA was stable under outdoor conditions. These results indicate that the root dsRNA soaking can be used as a bioinsecticide strategy during crop irrigation. PMID:25828885

    Pacific Northwest National Laboratory conducted video-based boat surveys to identify fall Chinook salmon (Oncorhynchus tshawytscha) spawning areas located in deep water (greater than 1 m) downstream of Bonneville Dam in fall 2004. This report documents the number and extent of Chinook salmon spawning near Ives and Pierce Islands of the Columbia River and is the sixth in a series of reports prepared since 1999. The main objectives of this study were to find deepwater spawning locations of fall Chinook salmon in the main Columbia River channel, collect additional data on physical habitat parameters at spawning sites, and provide estimates of adult spawners in the surveyed area. The primary search area was adjacent to the upper portion of Pierce Island, and the secondary search zone was downstream of this area near the lower portion of Pierce Island. A secondary objective was to document the occurrence of any chum salmon (O. keta) redds in the deeper sections downstream of Hamilton Creek (slough zone search area). Fall Chinook salmon redd numbers were down slightly from the record number found during 2003. The number of fall Chinook redds found in the Ives-Pierce Island complex (river km 228.5) during 2004 was 293, which does not include the number of shallow water redds found by visual observation by boat by the Oregon Department of Fish and Wildlife. The redds encompassed an area of 14.6 ha occurring adjacent to the lower part of Ives Island and Pierce Island. Peak spawning activity, based on redd counts and live fish seen near redds, was on or near November 16, 2004. An expanded redd count based on percentage video coverage in the primary and secondary search zones was 3,198 fall Chinook salmon redds at water depths exceeding approximately 1.0 m (approximately 125 kcfs) with an estimated spawning population of 10,800. Fall Chinook salmon redds were found at water depths from 1.07 to 7.6 m and were constructed predominantly of medium cobbles ranging in size from 7

    In 1999, crop consultants scouting for stink bugs (Hemiptera spp.) in South Carolina discovered a formerly unobserved seed rot of cotton that caused yield losses ranging from 10 to 15% in certain fields. The disease has subsequently been reported in fields throughout the southeastern Cotton Belt. Externally, diseased bolls appeared undamaged; internally, green fruit contain pink to dark brown, damp, deformed lint, and necrotic seeds. In greenhouse experiments, we demonstrated transmission of the opportunistic bacterium Pantoea agglomerans by the southern green stink bug, Nezara viridula (L.). Here, green bolls were sampled from stink bug management plots (insecticide protected or nontreated) from four South Atlantic coast states (North Carolina, South Carolina, Georgia, and Florida) to determine disease incidence in the field and its association with piercing-sucking insects feeding. A logistic regression analysis of the boll damage data revealed that disease was 24 times more likely to occur (P = 0.004) in bolls collected from plots in Florida, where evidence of pest pressure was highest, than in bolls harvested in NC with the lowest detected insect pressure. Fruit from plots treated with insecticide, a treatment which reduced transmission agent numbers, were 4 times less likely to be diseased than bolls from unprotected sites (P = 0.002). Overall, punctured bolls were 125 times more likely to also have disease symptoms than nonpunctured bolls, irrespective of whether or not plots were protected with insecticides (P = 0.0001). Much of the damage to cotton bolls that is commonly attributed to stink bug feeding is likely the resulting effect of vectored pathogens.

    The xylem-limited bacterium Xylella fastidiosa (Xf) causes Pierce's disease (PD), an important disease of grapevine, Vitis vinifera L. Grapevine rootstocks were developed to provide increased resistance to root disease, but rootstock effects on cane and vine diseases remain unclear. Grapevines that consisted of Cabernet Sauvignon or Chardonnay grafted to 13 different rootstocks were inoculated with Xf and evaluated for PD severity and Xf titer after 6 months. A subset of six rootstock/scion combinations had xylem sap phenolic levels assessed in non-infected and Xf-infected grapevines. Vigor also was analyzed by measuring root lengths and masses. Cabernet Sauvignon grafted to 101-14MG, 1103P, 420A, or Schwarzmann had reduced PD severity compared to Cabernet Sauvignon grafted to 110R, 5BB, or SO4. Chardonnay grafted to Salt Creek or Freedom had reduced PD severity compared to Chardonnay grafted to RS3 or Schwarzmann. Chardonnay grafted to RS3 had greater Xf titer than Chardonnay grafted to 101-14MG, Freedom, or Salt Creek. No other differences in Xf titer among rootstocks were observed. Of the six scion/rootstock combinations which had xylem sap phenolics analyzed, Chardonnay/RS3 had the highest levels of most phenolics whereas Cabernet Sauvignon/101-14MG had the lowest phenolic levels. However, Chardonnay/101-14MG, which had mild PD symptoms, had greater sap levels of caftaric acid than other scion/rootstock combinations. Sap levels of caftaric acid, methyl salicylate, a procyanidin trimer, and quinic acid were greater in Xf-infected vs. non-infected grapevines. Chardonnay on 101-14MG or Salt Creek had greater root mass than Chardonnay on RS3. Cabernet Sauvignon on 101-14MG had greater root mass than Cabernet Sauvignon on 110R. These results identified rootstocks with the capacity for reducing PD symptom progression. Rootstocks also were shown to affect Xf titer, xylem sap phenolic levels, and plant vigor. PMID:24376452

    Fall chinook salmon (Oncorhynchus tshawytscha), thought to originate from Bonneville Hatchery, were first noted to be spawning downstream of Bonneville Dam by Washington Department of Fisheries and Wildlife (WDFW) biologists in 1993 (Hymer 1997). Known spawning areas included gravel beds on the Washington side of the river near Hamilton Creek and Ives Island. The size of this population from 1994 to 1996 was estimated at 1,800 to 5,200 fish (Hymer 1997), and 554 fish in 1998 (Van der Naald et al. 1999). These estimates were based on carcass surveys and visual observation of redds by boat near the shoreline. Pacific Northwest National Laboratory (PNNL) conducted underwater video surveys in the fall of 1999 and 2000 to determine the extent of the fall chinook salmon spawning and to estimate the number of redds occurring in deeper water. Estimates of redds occurring in water depths exceeding 2.2 m at 143,000 cubic feet per second (kcfs) were 499 in 1999 (Mueller and Dauble 1999) and 567 redds >2.2 m at 127 kcfs in 2000 (this study). The majority of the redds found were confined near the main river channel adjacent to Pierce Island. Chum salmon (O. keta) also have been documented using the mouth of Hamilton Creek and portions of Hamilton Slough for spawning. The majority of chum salmon were found to spawn in shallow water at the mouth of Hamilton Creek adjacent to Ives Island. Estimates of the natural chum salmon spawning population for 1998 were 226 (Van der Naald et al. 1999). Chum salmon spawning near Ives Island are part of the Columbia River evolutionary significant unit (ESU), and are included in the Endangered Species Act of 1973 (ESA) listing in March 1999. Our main objective of this study was to locate deep water spawning locations of fall chinook salmon in the main Columbia River channel and to collect additional data on physical habitat parameters at spawning sites. The secondary objective was to map any chum salmon redds located in the deep sections of

    The Olalla 7.5' quadrangle, which lies almost in the center of the Puget Lowland, displays the broad range of geologic environments typical of the region. The upland plain is fluted by the passage of the great continental ice sheet that last covered the area about 17,000 (14,000 radiocarbon) years ago. The plain is cut by channel deposits, both late glacial and postglacial in age, and it is cleaved even more deeply by one of the major arms of Puget Sound, Colvos Passage, which here separates the west coast of Vashon Island from the Kitsap Peninsula. Beneath the deposits of the last ice sheet is a complex sequence of older Quaternary-age sediments that extends about 400 m below the modern ground surface. These older sediments are best exposed along the shorelines and beach cliffs of Puget Sound, where wave action and landslides maintain relatively fresh exposures. The older sediments typically are compact, having been loaded by ice during one or more episodes of glaciation subsequent to their deposition. Locally these sediments are also cemented by iron and manganese oxides and hydroxides, a consequence of many tens or hundreds of thousands of years of weathering and groundwater movement. Our map is an interpretation of a 6-ft resolution lidar-derived digital elevation model combined with the geology depicted on the "Geologic map of the Olalla 7.5' quadrangle, King, Kitsap, and Pierce Counties, Washington," by Booth and Troost (2005), which was described, interpreted, and located on the 1953 1:24,000-scale topographic map of the Olalla 7.5-minute quadrangle. The original topographic base map, derived from 1951 aerial photographs, has 20-ft contours, nominal horizontal resolution of circa 40 ft (12 m), and nominal mean vertical accuracy of circa 13 ft (4 m). This new DEM has a horizontal resolution of 6 ft (2 m) and mean vertical accuracy circa 1 ft (0.3 m). The greater resolution and accuracy of the lidar DEM facilitated a much-improved interpretation of many

    We compared microstructures of Late Pre-Cambrian to Early Cambrian Ara Salt diapirs from the deep subsurface (3.5-5 km) of the South Oman Salt Basin and from surface-piercing salt domes of the Ghaba Salt Basin. Laterally, these basins are approximately 500 km apart but belong to the same tectono-sedimentary system. The excellent data situation from both wells and outcrops allows a unique quantification of formation and deformation mechanisms, spanning from sedimentation to deep burial, and via re-activated diapir rise to surface piercement. Microstructures of gamma-irradiated and etched thin sections indicate dislocation creep and fluid-assisted grain boundary migration as the main deformation mechanisms operating in the deep subsurface. Microstructures from the surface are characterised by large ‘old’ subgrain-rich crystals. These ‘old’ grains are partly replaced by ‘new’ subgrain-free and subgrain-poor crystals, which show gamma irradiation-decorated growth bands and fibrous microstructures, indicative of pressure solution creep and static recrystallisation, most likely due to surface piercement and exposure. Using subgrain size piezometry, the maximum differential stresses for the subsurface salt is 1.7 MPa and those for the surface-piercing salt is 3.4 MPa, the latter value displaying the high stress conditions in the diapir ‘stem’ as the salt rises on its way to the surface.

    Staff who work in facilities such as health care, dentistry, drug treatment, and tattoo/body piercing are likely to encounter persons with hepatitis C virus (HCV) and be privy to their HCV status. The purpose of this paper is to assess staff comfort with varying levels of intimacy (i.e., social distance) with people who have HCV. We examine how previous contact with persons with HCV and knowledge of HCV including HCV specific training affect desire for social distance. Data are from a 2007 sample of 82 individuals working in health care, dentistry, drug treatment, or tattoo/body-piercing studios located in the Pacific Northwest region of the United States. Multivariate analyses indicate that staff desire social distance from persons with HCV, but contact of certain types reduce desire for social distance. We discuss how the findings have implications for people employed in these fields, as they point to the need to dispel myths and reduce fear among staff working in facilities that may serve persons with HCV.

    This report presents information used to characterize the groundwater-flow system in the Chambers-Clover Creek Watershed and vicinity, and includes descriptions of the geology and hydrogeologic framework; groundwater recharge and discharge; groundwater levels and flow directions; seasonal groundwater level fluctuations; interactions between aquifers and the surface-water system; and a water budget. The study area covers about 706 square miles in western Pierce County, Washington, and extends north to the Puyallup River, southwest to the Nisqually River, and is bounded on the south and east by foothills of the Cascade Range and on the west by Puget Sound. The area is underlain by a northwest-thickening sequence of unconsolidated glacial and interglacial deposits which overlie sedimentary and volcanic bedrock units that crop out in the foothills along the southern and southeastern margin of the study area. Geologic units were grouped into 11 hydrogeologic units consisting of aquifers, confining units, and an underlying bedrock unit. A surficial hydrogeologic unit map was developed and used with well information from 450 drillers' logs to construct 6 hydrogeologic sections, and unit extent and thickness maps. Groundwater in unconsolidated glacial and interglacial aquifers generally flows to the northwest towards Puget Sound, and to the north and northeast towards the Puyallup River. These generalized flow patterns likely are complicated by the presence of low permeability confining units that separate discontinuous bodies of aquifer material and act as local groundwater-flow barriers. Water levels in wells completed in the unconsolidated hydrogeologic units show seasonal variations ranging from less than 1 to about 50 feet. The largest groundwater-level fluctuation (78 feet) observed during the monitoring period (March 2007-September 2008) was in a well completed in the bedrock unit. Synoptic streamflow measurements made in September 2007 and July 2008 indicated a

    A groundwater-flow model was developed to contribute to an improved understanding of water resources in the Chambers-Clover Creek Watershed. The model covers an area of about 491 square miles in western Pierce County, Washington, and is bounded to the northeast by the Puyallup River valley, to the southwest by the Nisqually River valley, and extends northwest to Puget Sound, and southeast to Tanwax Creek. The Puyallup and Nisqually Rivers occupy large, relatively flat alluvial valleys that are separated by a broad, poorly drained, upland area that covers most of the model area. Chambers and Clover Creeks drain much of the central uplands and flow westward to Puget Sound. The model area is underlain by a northwest-thickening sequence of unconsolidated glacial (till and outwash) and interglacial (fluvial and lacustrine) deposits. Ten unconsolidated hydrogeologic units in the model area form the basis of the groundwater-flow model. Groundwater flow in the Chambers-Clover Creek Watershed and vicinity was simulated using the groundwater-flow model, MODFLOW-2000. The finite-difference model grid comprises 146 rows, 132 columns, and 11 layers. Each model cell has a horizontal dimension of 1,000 by 1,000 feet, and the model contains a total of 123,602 active cells. The thickness of model layers varies throughout the model area and ranges from 1.5 feet in the A3 aquifer unit to 1,567 feet in the G undifferentiated unit. Groundwater flow was simulated for both steady-state and transient conditions. Steady-state conditions were simulated using average recharge, discharge, and water levels for the 24-month period September 2006-August 2008. Transient conditions were simulated for the period September 2006-August 2008 using 24 monthly stress periods. Resource managers and local stakeholders intend to use the model to evaluate a range of water resource issues under both steady-state and transient conditions. Initial conditions for the transient model were developed from a 3-year

    Pacific Northwest National Laboratory conducted video-based boat surveys in fall 2003 to identify spawning areas for fall Chinook salmon (Oncorhynchus tshawytscha) in deep water (>1 m) downstream of Bonneville Dam. This report documents the number and extent of Chinook salmon spawning near Ives and Pierce islands of the Columbia River, and is the fifth in a series of reports prepared since 1999. The primary objective of this study was to find deepwater spawning locations of fall Chinook salmon in the main Columbia River channel, collect additional data on physical habitat parameters at spawning sites, and provide estimates of adult spawners in the surveyed area. The secondary objective was to document the occurrence of any chum salmon (O. keta) redds in the deeper sections near below Hamilton Creek. Results from the 2003 study show a continuing trend upward in the number of fall Chinook salmon redds found within the survey zones. The number of fall Chinook redds found in the Ives Pierce Island complex (river km 228.5) has increased by a factor of five since the surveys began in 1999. The total number of redds found during 2003 was 336, which compares to 192 in 2002, 43 in 2001, 76 in 2000, and 64 in 1999. The redds encompassed an area of 13.7 ha occurring adjacent to the lower part of Ives Island and Pierce Island. Peak spawning activity, based on redd counts and live fish seen near redds, was on or near November 24, 2003. An expanded redd count based on percentage of video coverage in the primary and secondary search zones was 3,218 fall Chinook salmon redds in water exceeding 1 m deep and flowing at about 125 kcfs. Fall Chinook salmon redds were found at water depths from 1.07 to 7.6 m and were constructed predominantly of medium cobbles ranging from 7.6 to 15.2 cm in diameter. Two chum salmon redds were found in a small location downstream from Hamilton Creek in water depths of approximately 1 m. No salmon redds were found in other areas searched, including near

    The Storfjorden in the Svalbard Archipelago (Norwegian Arctic Ocean) is a sill-fjord with an active polynya where intense sea ice formation produces significant amounts of near-freezing brine-enriched shelf water, which flows over the sill and sinks into Fram Strait down the continental slope of Western Svalbard as a dense plume from the sill depth of 115m. On its downward descent the dense water encounters a layer of warm, saline Atlantic Water that occupies the upper layer of the West Spitsbergen current within a depth range of approximately 200-500m. Hydrographic observations in the Storfjorden overflow region have been carried out over the past 30 years. In some years the Storfjorden cascade has been observed to reach depths of over 2000m in Fram Strait, where it shows up within the Norwegian Sea Deep Water as a temperature maximum due to the heat gained by turbulent mixing as the plume pierces through the warm Atlantic Water. At other times the cascade was arrested within the layer of Atlantic Water. It has been unclear what parameters control whether the piercing would take place or not. The eventual depth of the cascaded waters has a proven effect on the maintenance of the Arctic halocline and (when piercing occurs) the ventilation of the deep Arctic basins. Due to its location at the gateway into the Arctic Ocean, the Storfjorden cascade plays an important role in modifying the properties of the Atlantic Water inflow into the Arctic. We use a high-resolution 3-D numerical ocean model (NEMO) to simulate the descent of a cascade of saline and near-freezing shelf water into simplified, yet realistic, ambient stratification on an idealised conical slope based on the bathymetry of western Svalbard and Fram Strait. The model uses 1 km horizontal resolution and 42 layers in the vertical. The vertical grid is a complex combination of s- and z- coordinates specifically designed for this study. In a series of model runs we vary mainly the inflow rate 'Q' and the

    The type of host tissues and cells ingested by piercing and sucking insects greatly affects their nutrient intake, which may subsequently affect insect fitness. This study describes the sex differences in feeding site selection between male and female nymphs of the Chinese white wax scale insect (CWWS), Ericerus pela (Chavannes), feeding on leaves of the Chinese privet, Ligustrum lucidum. Our data showed that the stylet tips of female nymphs terminated in the phloem sieve elements of main or lateral veins, while those of male nymphs terminated in the palisade parenchyma. We concluded that female nymphs fed from sieve elements and males fed from parenchyma cells. The potential impact of these feeding patterns was discussed in relation to the selection of a site for attachment, nutrient acquisition, and mouthpart stretching mechanism. Among these factors, selection of a site for attachment and mouthpart stretching mechanism may be the main cause of sex differences in feeding sites between female and male nymphs of CWWS.

    Pacific Northwest National Laboratory conducted video-based boat surveys to identify fall chinook salmon (Oncorhynchus tshawytscha) spawning areas located in deep water (>1 m) downstream of Bonneville Dam in the fall of 2002. This report documents the number and extent of chinook salmon spawning near Ives and Pierce Islands of the Columbia River, and is the fourth in a series of reports prepared since 1999. The main objective of this study was to find deepwater spawning locations of fall chinook salmon in the main Columbia River channel, collect additional data on physical habitat parameters at spawning sites, and provide estimates of adult spawners in the surveyed area. The secondary objective was to document the occurrence of any chum salmon (O. keta) redds located in the deeper sections near below Hamilton Creek. There was a significant increase in the number of fall chinook salmon redds found in the locations surveyed during the 2002 surveys when compared to previous surveys by Pacific Northwest National Laboratory. A total of 192 redds were found in two general locations adjacent to Pierce Island (river km 228.5) encompassing an area of approximately 9.31 ha. Peak spawning activity, based on redd counts and live fish seen near redds, was on or near November 15, 2002. An estimated 1,768 fall chinook salmon redds at water depths exceeding {approx}1.m ({approx} 125 kcfs) were documented in 2002. This estimate is the expanded number based on the number of redds found within the pre-defined survey area. Fall chinook salmon redds were found at water depths from 0.9 to 8.5 m and were constructed in gravel to large cobble ranging in size from 4.83 to 13.4 cm in diameter. No chum salmon redds were found in areas surveyed during 2002, although several carcasses were found at the mouth of Woodward Creek and in the deeper sections below Hamilton Creek.

    Folate and vitamin B-12 are essential for normal brain development. Few studies have examined the relationship of maternal folate and vitamin B-12 status during pregnancy and offspring cognitive function. To test the hypothesis that lower maternal plasma folate and vitamin B-12 concentrations and higher plasma homocysteine concentrations during pregnancy are associated with poorer neurodevelopment, 536 children (aged 9-10 y) from the Mysore Parthenon birth cohort underwent cognitive function assessment during 2007-2008 using 3 core tests from the Kaufman Assessment Battery, and additional tests measuring learning, long-term storage/retrieval, attention and concentration, and visuo-spatial and verbal abilities. Maternal folate, vitamin B-12, and homocysteine concentrations were measured at 30 +/- 2 wk gestation. During pregnancy, 4% of mothers had low folate concentrations (<7 nmol/L), 42.5% had low vitamin B-12 concentrations (<150 pmol/L), and 3% had hyperhomocysteinemia (>10 micromol/L). The children's cognitive test scores increased by 0.1-0.2 SD per SD increase across the entire range of maternal folate concentrations (P < 0.001 for all), with no apparent associations at the deficiency level. The associations with learning, long-term storage/retrieval, visuo-spatial ability, attention, and concentration were independent of the parents' education, socioeconomic status, religion, and the child's sex, age, current size, and folate and vitamin B-12 concentrations. There were no consistent associations of maternal vitamin B-12 and homocysteine concentrations with childhood cognitive performance. In this Indian population, higher maternal folate, but not vitamin B-12, concentrations during pregnancy predicted better childhood cognitive ability. It also suggests that, in terms of neurodevelopment, the concentration used to define folate deficiency may be set too low. PMID:20335637

    Objectives Most studies reporting evidence of adverse effects of lead and cadmium on the ability to balance have been conducted in high-exposure groups or have included adults. The effects of prenatal exposure have not been well studied, nor have the effects in children been directly studied. The aim of the study was to identify the associations of lead (in utero and in childhood) and cadmium (in utero) exposure with the ability to balance in children aged 7 and 10 years. Design Prospective birth cohort study. Participants Maternal blood lead (n=4285) and cadmium (n=4286) levels were measured by inductively coupled plasma mass spectrometry in women enrolled in the Avon Longitudinal Study of Parents and Children (ALSPAC) during pregnancy. Child lead levels were measured in a subsample of 582 of ALSPAC children at age 30 months. Main outcome measures Children completed a heel-to-toe walking test at 7 years. At 10 years, the children underwent clinical tests of static and dynamic balance. Statistical analysis using SPSS V.19 included logistic regression modelling, comparing categories of ≥5 vs <5 µg/dL for lead, and ≥1 vs <1 µg/L for cadmium. Results Balance at age 7 years was not associated with elevated in utero lead or cadmium exposure (adjusted OR for balance dysfunction: Pb 1.01 (95% CI 0.95 to 1.01), n=1732; Cd 0.95 (0.77 to 1.20), n=1734), or with elevated child blood lead level at age 30 months (adjusted OR 0.98 (0.92 to 1.05), n=354). Similarly, neither measures of static nor dynamic balance at age 10 years were associated with in utero lead or cadmium exposure, or child lead level. Conclusions These findings do not provide any evidence of an association of prenatal exposure to lead or cadmium, or lead levels in childhood, on balance ability in children. Confirmation in other cohorts is needed. PMID:26719320

    Abstract A high residential altitude impacts on the growth of children, and it has been suggested that linear growth (height) is more affected than body mass. The aim of the present study was to estimate the prevalence of obesity, overweight, underweight, and stunting in groups of native Tibetan children living at different residential altitudes (3700 vs 4300 m above sea level) and across ancestry (native Tibetan vs Han Chinese children living at the same altitude of 3700 m), as well as to examine the total effect of residential altitude and ancestry with stunting. Two cross-sectional studies of 1207 school children aged 9 to 10 years were conducted in Lhasa in 2005 and Tingri in 2007. Conventional age- and sex-specific cutoff values were used for defining underweight, normal weight, overweight, or obesity, whereas stunting was defined from sex-specific height-for-age z-scores (≤−2.0). The prevalence of underweight was high at 36.7% among Tingri Tibetan girls and 31.1% in Tingri Tibetan boys. The prevalence was statistically significant lower in Lhasa Tibetan girls (20.2%) than in both Tingri Tibetan girls and Han Chinese girls (33.7%), with a similar trend seen among boys. Severe and moderate stunting were found in 14.6% and 35.7%, respectively, of Tingri children, and near null among Han Chinese and native Tibetans in Lhasa. In logistic regression analyses, socioeconomic status and diet did not substantially change the observed crude association (total effect) (odds ratio [OR] = 3.3; 95% confidence interval [CI] 1.1–10.3) between ancestry and stunting. Similarly, adjustment for diet did not alter the crude association (direct effect) (OR = 101.3; 95% CI 37.1–276.4) between residential altitude and stunting. The prevalence estimates of stunting and underweight were high, and clearly higher among native Tibetan children living at a higher residential altitude (Tingri) than the lower residential altitude (Lhasa), in addition to being higher among Han Chinese children than Tibetan children living at the same residential altitude (Lhasa). Thus, physical growth according to age, in terms of both height and weight, affected children living at an altitude of 4300 m above sea level. PMID:26496254

    Folate and vitamin B-12 (B-12) are essential for normal brain development. Few studies have examined the relationship of maternal folate and B-12 status during pregnancy to offspring cognitive function. To test the hypothesis that lower maternal plasma folate and B-12 concentrations and higher plasma homocysteine concentrations during pregnancy, are associated with poorer neurodevelopment, cognitive function was assessed during 2007-2008 among 536 children (aged 9-10 y) from the Mysore Parthenon birth cohort. Maternal folate, B-12 and homocysteine concentrations were measured in stored plasma samples taken at 30±2 wk gestation. The children’s cognitive function was measured using 3 core tests from the Kaufman Assessment Battery and additional tests measuring learning ability, long-term storage/retrieval, attention and concentration, visuo-spatial and verbal abilities. During pregnancy 4% of mothers had low folate concentrations (<7 nmol/L), 42.5% had low B-12 concentrations (<150 pmol/L) and 3% had hyperhomocysteinemia (>10 μmol/L). There was a 0.1-0.2 SD increase in the children’s cognitive scores per SD increase in maternal folate concentration (p<0.001 for all tests). The associations with learning ability and long-term storage/retrieval, visuo-spatial ability, attention and concentration were independent of maternal age, BMI, parity, the parents’ education, socio-economic status, rural/urban residence, religion, the child’s gestational age, birth size, sex and the children’s size, educational level and folate and B-12 concentrations at 9.5 y. There were no consistent associations of maternal B-12 and homocysteine concentrations with childhood cognitive performance. Conclusions In this Indian population higher maternal folate, but not vitamin B-12 concentrations during pregnancy, predicted better childhood cognitive ability. PMID:20335637

  15. A New Era in Solar Thermal-IR Astronomy: the NSO Array Camera (NAC) on the McMath-Pierce Telescope

    The U.S. National Solar Observatory Array Camera (NAC) is a cryogenically cooled 1Kx1K InSb ``Aladdin" array that recently became operational at the McMath-Pierce facility on Kitt Peak, a high dry site in the southwest U.S. (Arizona). The new camera is similar to those already incorporated into instruments on nighttime telescopes, and has unprecedented sensitivity, low noise, and excellent cosmetics compared with the Amber Engineering (AE) device it replaces. (The latter was scavenged from a commercial surveillance camera in the 1990's: only 256X256 format, high noise, and annoying flatfield structure). The NAC focal plane is maintained at 30 K by a mechanical closed-cycle helium cooler, dispensing with the cumbersome pumped--solid-N2 40 K system used previously with the AE camera. The NAC linearity has been verified for exposures as short as 1 ms, although latency in the data recording holds the maximum frame rate to about 8 Hz (in "streaming mode"). The camera is run in tandem with the Infrared Adaptive Optics (IRAO) system. Utilizing a 37-actuator deformable mirror, IRAO can--under moderate seeing conditions--correct the telescope image to the diffraction limit longward of 2.3 mu (if a suitable high contrast target is available: the IR granulation has proven too bland to reliably track). IRAO also provides fine control over the solar image for spatial scanning in long-slit mode with the 14 m vertical "Main" spectrograph (MS). A 1'X1' area scan, with 0.5" steps orthogonal to the slit direction, requires less than half a minute, much shorter than p-mode and granulation evolution time scales. A recent engineering test run, in April 2008, utilized NAC/IRAO/MS to capture the fundamental (4.6 mu) and first-overtone (2.3 mu) rovibrational bands of CO, including maps of quiet regions, drift scans along the equatorial limbs (to measure the off-limb molecular emissions), and imaging of a fortuitous small sunspot pair, a final gasp, perhaps, of Cycle 23.

    We examined the apoptotic effect of a novel Probiotics Fermentation Technology (PFT) kefir grain product; PFT is a natural mixture composed primarily of Lactobacillus kefiri P-IF, a specific strain of L. kefiri with unique growth characteristics. The aim of this study was to examine the apoptotic effect of PFT on human multidrug-resistant (MDR) myeloid leukemia (HL60/AR) cells in vitro and explore the mechanistic approach underlying its effect. HL60/AR cells were cultured with PFT (0.6–5.0 mg/ml) for 3 days. The apoptotic effect of PFT was assessed through examination of percent apoptosis, caspase 3 activation, Bcl-2 expression levels and changes in mitochondrial membrane potential (MMP). PFT induced apoptosis in HL60/AR cells in a dose-dependent manner which was maximal at 67.5% for 5 mg/ml. Induction of apoptosis was associated with activation of caspase 3, decreased expression of Bcl-2 and decreased polarization of MMP. In addition, PFT showed a unique characteristic of piercing holes in HL60/AR cells, as indicated by AFM studies. This hole induction may be responsible for the apoptotic effect on cancer cells. These results suggest that PFT may act as a potential therapy for the treatment of MDR leukemia. PMID:24430613

    Fall chinook salmon Oncorhynchus tshawytscha, thought to originate from Bonneville Hatchery, were first noted to be spawning downstream of Bonneville Dam by Washington Department of Fisheries and Wildlife (WDFW) biologists in 1993 (Hymer 1997). Known spawning areas include gravel beds on the Washington side of the river near Hamilton Creek and Ives island. Limited spawning ground surveys were conducted in the area around Ives and Pierce Islands during 1994-1997 and based on these surveys it was believed that fall chinook salmon successfully spawned in this area. The size of this population from 1994 to 1996 was estimated at 1,800 to 5,200 fish (Hymer 1997). Recently, chum salmon were also documented spawning downstream of Bonneville Dam. Chum salmon O. kisutch were listed as threatened under the Endangered Species Act (ESA) in March, 1999. There are several ongoing investigations to define the physical habitat characteristics associated with fall chinook and chum salmon spawning areas downstream of Bonneville Dam. A major concern is to determine what flows (i.e. surface elevations) are necessary to ensure their long-term survival. Our objective was to locate deepwater spawning locations in the main Columbia River channel and to collect additional data on physical habitat parameters at the site. This objective is consistent with the high priority that the Northwest Power Planning Council's Independent Advisory Board and the salmon managers have placed on determining the importance of mainstem habitats to the production of salmon in the Columbia River Basin.

    Due to its extreme sexual dimorphism and disparate hosts, no female myrmecolacid has been matched to its conspecific male to date. Here, for the first time to our knowledge, a morphological description is given of the matched female and male myrmecolacid, Caenocholax fenyesi waloffi ssp. nov. from Veracruz, Mexico: the female parasitic in a cricket and the male parasitic in an ant. For examined segments of DNA, the male and female are identical. Male C. fenyesi Pierce sensu lato was described 94 years ago from Veracruz. The male from Texas USA, which, for the same DNA segments, shows 15% divergence from the morphologically identical male from Veracruz, is given subspecies status, and is named Caenocholax fenyesi texensis ssp. nov. The discovery of the female finally enables many interesting studies to be pursued, such as speciation in morphologically cryptic taxa, the sexes of which parasitize disparate hosts. Caenocholax fenyesi sensu lato may also be evaluated for biocontrol of the red imported fire ant, Solenopsis invicta Buren, which is a pest in the USA and Australia. PMID:15101403

    Xylella fastidiosa is an important phytopathogenic bacterium that causes many serious plant diseases including Pierce's disease of grapevines. X. fastidiosa is thought to induce disease by colonizing and clogging xylem vessels through the formation of cell aggregates and bacterial biofilms. Here we examine the role in X. fastidiosa virulence of an uncharacterized gene, PD1671, annotated as a two-component response regulator with potential GGDEF and EAL domains. GGDEF domains are found in c-di-GMP diguanylate cyclases while EAL domains are found in phosphodiesterases, and these domains are for c-di-GMP production and turnover, respectively. Functional analysis of the PD1671 gene revealed that it affected multiple X. fastidiosa virulence-related phenotypes. A Tn5 PD1671 mutant had a hypervirulent phenotype in grapevines presumably due to enhanced expression of gum genes leading to increased exopolysaccharide levels that resulted in elevated biofilm formation. Interestingly, the PD1671 mutant also had decreased motility in vitro but did not show a reduced distribution in grapevines following inoculation. Given these responses, the putative PD1671 protein may be a negative regulator of X. fastidiosa virulence. PMID:25811864

    The American Lake Gardens (McChord AFB-Area D) site is an active U.S. Air Force base located at McChord Air Force Base, Pierce County, Washington. The site consists of two areas, Area D and American Lake Garden Tract (ALGT). From the mid-1940's to the present, no known industrial activities have occurred in the ALGT area; however, seven waste disposal sites have operated within the Area D portion of the site. Concurrent with DOD investigations, EPA discovered TCE in ground water monitoring wells installed at the ALGT, and in 1984, concluded that waste disposal sites in Area D were the likely source of ground water contamination. The ROD addresses remediation of the contaminated onsite and offsite ground water plume, as a final remedy. The primary contaminants of concern affecting the ground water are VOCs including benzene, PCE, TCE, toluene, and xylenes; other organics; and metals including arsenic, chromium, and lead. The selected remedial action for the site is included.

    Comet C/2012 S1 (ISON) is unique in that it is a dynamically new comet derived from the Oort cloud reservoir of comets with a sun-grazing orbit. Infrared (IR) and visible wavelength observing campaigns were planned on NASA's Stratospheric Observatory For Infrared Astronomy (SOFIA) and on National Solar Observatory Dunn (DST) and McMath-Pierce Solar Telescopes, respectively. We highlight our SOFIA (+FORCAST) mid- to far-IR images and spectroscopy (approx. 5-35 microns) of the dust in the coma of ISON are to be obtained by the ISON-SOFIA Team during a flight window 2013 Oct 21-23 UT (r_h approx. = 1.18 AU). Dust characteristics, identified through the 10 micron silicate emission feature and its strength, as well as spectral features from cometary crystalline silicates (Forsterite) at 11.05-11.2 microns, and near 16, 19, 23.5, 27.5, and 33 microns are compared with other Oort cloud comets that span the range of small and/or highly porous grains (e.g., C/1995 O1 (Hale-Bopp) and C/2001 Q4 (NEAT) to large and/or compact grains (e.g., C/2007 N4 (Lulin) and C/2006 P1 (McNaught)). Measurement of the crystalline peaks in contrast to the broad 10 and 20 micron amorphous silicate features yields the cometary silicate crystalline mass fraction, which is a benchmark for radial transport in our protoplanetary disk. The central wavelength positions, relative intensities, and feature asymmetries for the crystalline peaks may constrain the shapes of the crystals. Only SOFIA can look for cometary organics in the 5-8 micron region. Spatially resolved measurements of atoms and simple molecules from when comet ISON is near the Sun (r_h< 0.4 AU, near Nov-20-Dec-03 UT) were proposed for by the ISON-DST Team. Comet ISON is the first comet since comet Ikeya-Seki (1965f) suitable for studying the alkalai metals Na and K and the atoms specifically attributed to dust grains including Mg, Si, Fe, as well as Ca.

    The area around Ives Island below Bonneville Dam on the Columbia River supports spawning populations of chum and fall chinook salmon. Because this area is sensitive to water level fluctuations caused by changes in discharge from Bonneville Dam and from tidal cycles, we initiated a study to quantify flow-dependent changes in available spawning habitat for chum and fall chinook salmon. We conducted surveys to characterize the substrates available in the Ives Island study area. Detailed bathymetry was also obtained to serve as a foundation for two-dimension hydrodynamic modeling, which was used to estimate water velocities, depths, and wetted area over a range of simulated flows. Habitat surveys were conducted and logistic regression was used to identify physical habitat variables that were important in determining the presence of chum and fall chinook salmon redds. The physical habitat data were analyzed using the logistic regression models to create probability coverages for the presence of redds in a Geographic Information System. There was generally good agreement between chum and fall chinook salmon redd locations and areas where we predicted suitable spawning habitat. We found that at Columbia River discharges less than 120 kcfs, an important chum salmon spawning area below the mouth of Hamilton Creek could only be supported by discharge from Hamilton Creek. Chum salmon did not appear to spawn in proportion to habitat availability, however our predictive model did not include all variables known to be important to chum salmon redd-site selection. Fall chinook salmon spawning habitat was less sensitive to flow and the main channel of the Columbia River along Pierce Island was predicted to contain sufficient habitat at all modeled flows.

    Pacific Northwest National Laboratory initiated studies to identify potential fall chinook salmon (Oncorhynchus tshawytscha) spawning habitat and assess the extent of spawning in deep water (>1 m) downstream of Bonneville Dam in the fall of 1999. This report provides results from 2001, the third year of our effort. The main objective of this study was to find deepwater spawning locations of fall chinook salmon in the main Columbia River channel, collect additional data on physical habitat parameters at spawning sites, and provide estimates of adult spawners in the area. The secondary objective was to map any chum salmon redds located in the deeper sections near Hamilton Slough. River flows during the spawning surveys in 2001 were lower than in 1999 and 2000. Peak spawning activity, based on redd counts and live fish seen near redds, was on or near November 9, 2001. The location of the spawning area was similar to that of 1999 and 2000. One difference was the majority of redds were found in deeper water (>1.5 m) and closer to the shoreline adjacent to Pierce Island. Because of the low river flows during the fall of 2001, only a handful of redds were found using the boat-deployed video system within Hamilton Slough. No chum salmon (O. keta) redds were found in areas surveyed during 2000. (Note: surveys were limited to deeper sections of Hamilton Slough and near the main river channel.) An estimated 717 fall chinook salmon redds at water depths exceeding 1.5 m ({approx} 125 kcfs) were documented in 2001. These estimates are expanded from the number of redds found within a predefined survey area. Fall chinook salmon redds were found at water depths from 1.5-4.6 m and were located in a general area of {approx} 4.9 ha. Fall chinook salmon redds were constructed in gravels ranging from 3.2-13.4 cm in diameter and water velocities of 0.29-0.70 m/s.

    Plant defensive strategies bring into play blends of compounds dependent on the type of attacker and coming from different synthesis pathways. Interest in the field is mainly focused on volatile organic compounds (VOCs) and jasmonic acid (JA). By contrast, little is known about the oxidized polyunsaturated fatty acids (PUFAs), such as PUFA-hydroperoxides, PUFA-hydroxides, or PUFA-ketones. PUFA-hydroperoxides and their derivatives might be involved in stress response and show antimicrobial activities. Hydroperoxides are also precursors of JA and some volatile compounds. In this paper, the differential biochemical response of a plant against insects with distinct feeding behaviours is characterized not only in terms of VOC signature and JA profile but also in terms of their precursors synthesized through the lipoxygenase (LOX)-pathway at the early stage of the plant response. For this purpose, two leading pests of potato with distinct feeding behaviours were used: the Colorado Potato Beetle (Leptinotarsa decemlineata Say), a chewing herbivore, and the Green Peach Aphid (Myzus persicae Sulzer), a piercing-sucking insect. The volatile signatures identified clearly differ in function with the feeding behaviour of the attacker and the aphid, which causes the smaller damages, triggers the emission of a higher number of volatiles. In addition, 9-LOX products, which are usually associated with defence against pathogens, were exclusively activated by aphid attack. Furthermore, a correlation between volatiles and JA accumulation and the evolution of their precursors was determined. Finally, the role of the insect itself on the plant response after insect infestation was highlighted.

    Introduction Haemoglobin A1c (HbA1c) is widely used in the management of diabetes. Therefore, the reliability and comparability among different analytical methods for its detection have become very important. Materials and methods A comparative evaluation of the analytical performances (precision, linearity, accuracy, method comparison, and interferences including bilirubin, triglyceride, cholesterol, labile HbA1c (LA1c), vitamin C, aspirin, fetal haemoglobin (HbF), and haemoglobin E (Hb E)) were performed on Capillarys 2 Flex Piercing (Capillarys 2FP) (Sebia, France), Tosoh HLC-723 G8 (Tosoh G8) (Tosoh, Japan), Premier Hb9210 (Trinity Biotech, Ireland) and Roche Cobas c501 (Roche c501) (Roche Diagnostics, Germany). Results A good precision was shown at both low and high HbA1c levels on all four systems, with all individual CVs below 2% (IFCC units) or 1.5% (NGSP units). Linearity analysis for each analyzer had achieved a good correlation coefficient (R2 > 0.99) over the entire range tested. The analytical bias of the four systems against the IFCC targets was less than ± 6% (NGSP units), indicating a good accuracy. Method comparison showed a great correlation and agreement between methods. Very high levels of triglycerides and cholesterol (≥ 15.28 and ≥ 8.72 mmol/L, respectively) led to falsely low HbA1c concentrations on Roche c501. Elevated HbF induced false HbA1c detection on Capillarys 2FP (> 10%), Tosoh G8 (> 30%), Premier Hb9210 (> 15%), and Roche c501 (> 5%). On Tosoh G8, HbE induced an extra peak on chromatogram, and significantly lower results were reported. Conclusions The four HbA1c methods commonly used with commercial analyzers showed a good reliability and comparability, although some interference may falsely alter the result. PMID:27812304

    Pierce’s Disease (PD) of grapevines, caused by Xylella fastidiosa subsp. fastidiosa (Xf), is a limiting factor in the cultivation of grapevines in the US. There are presently no effective control methods to prevent or treat PD. The therapeutic and prophylactic efficacy of a phage cocktail composed of four virulent (lytic) phages was evaluated for control of PD. Xf levels in grapevines were significantly reduced in therapeutically or prophylactically treated grapevines. PD symptoms ceased to progress one week post-therapeutic treatment and symptoms were not observed in prophylactically treated grapevines. Cocktail phage levels increased in grapevines in the presence of the host. No in planta phage-resistant Xf isolates were obtained. Moreover, Xf mutants selected for phage resistance in vitro did not cause PD symptoms. Our results indicate that phages have great potential for biocontrol of PD and other economically important diseases caused by Xylella. PMID:26107261

    Transportation Accident Resistant Containers (TARC)s are used for enhanced safety during movement of nuclear weapons. Its design features a tough stainless steel outer skin, redwood for impact mitigation and fire protection and a rugged aluminum inner container. Redwood absorbs impact energy by crushing, similar to the way foam crushes in other containers. Redwood also functions to insulate the weapon from heat and fire. When a TARC is involved in a fire, the redwood will slowly burn forming a good insulating char. The redwood can continue to smolder once the fire is out. To ensure the smolder is extinguished, water can be directed into any accident caused hole in the skin. If no hole exists, it may be necessary to create one. This document discusses tool selection, testing, and a simple but effective method of creating an access hole in the outer skin large enough to apply fire fighting techniques.

    The Milky Way and its surrounding environs contain gas moving at high velocities with respect to the Sun. For the past half century, most of the information available for these high velocity clouds (HVCs) has come from H I 21cm surveys. Improvements in these surveys have recently led to the idea that some of the high velocity H I clouds may be located outside the Milky Way within the Local Group. Such a hypothesis is testable by various means, but the neutral gas content of the clouds tells only half of a much more complex story. In this talk I will present new information about the ionized gas within HVCs, their impact on the gaseous atmosphere of the Galaxy, and their relevance to the cosmic web of hot gas that may contain a significant fraction of the baryonic material in the low-redshift universe.

    We investigate the interaction between an infinite cylinder and a free fluid-fluid interface governed only by its surface tension. We study the deformation of an initially flat interface when it is deformed by the presence of a cylindrical object, tilted at an arbitrary angle, that the interface “totally wets”. Our simulations predict all significant quantities such as the interface shape, the position of the contact line, and the force exerted by the interface on the cylinder. These results are compared with an experimental study of the penetration of a soap film by a cylindrical liquid jet. This dynamic situation exhibits all the characteristics of a totally wetting interface. We show that whatever the inclination, the force is always perpendicular to the plane of the interface, and its amplitude diverges as the inclination angle increases. Such results should bring new insights in both fluid and solid mechanics, from animal locomotion to surface micro-processing.

I examine an historical case of ethnographic research and the sustained moral outrage to the research expressed by the subjects of that research. I suggest that the moral outrage was legitimate and articulate some of the ethical issues underlying that outrage. I argue that morally problematic Ethnographic research of public behavior can derive from research practice that includes a tendency to collapse the distinction between harm and moral wrong, a failure to take account of recent work on ethical issues in privacy; failure to appreciate the deception involved in ethnographers' failure to reveal their role as researchers to subjects and finally a failure to appropriately weigh the moral significance of issues of invasion of privacy and inflicted insight in both the research process and subsequent publication of research.

    In this essay, I enjoy using Amitabh Bachchan, perennial idol of the Bollywood screen, as a point of departure for ruminations on the construction of male friendship and male love within both Indian cinema and its primarily male audience (which, in a sense, represents in turn Hindi culture at large). Using translations of songs from Amitabh's films interlaced with my own personal experiences, we see how homosexuality thrives in covert yet recognized places in Indian culture, and how subtler forms of homosexuality are actually engendered under the auspices of normative patriarchal culture. Songs were translated by the author in collaboration with Jia Das.

  19. Jonathan Reichert and Barbara Wolff-Reichert Award: Updating Lab Curricula via the Tom Sawyer method of painting a fence

    NASA Astrophysics Data System (ADS)

    Spalding, Gabriel

    2014-03-01

    The undergraduate curriculum ought to provide a broad foundation for a career in experimental science. (After all, even theoretical physicists benefit from a foundational understanding of experimentalism - and may even, at some point in their careers, be called upon to teach undergraduate courses with labs.) Yet, while the teaching of mathematical formalism within the traditional physics major consists of an extended, ``spiral curriculum'' (which repeatedly revisits, reinforces, and refines key concepts), a great many programs would benefit from expanding the curricular ``space'' given to lab instruction: I will argue that research experience ought not be considered a substitute for the sort of broad grounding a full curriculum of lab instruction can provide. Most importantly, I will describe powerful ways in which we can help you to introduce new instructional lab modules (and models). Inertia is no longer a valid excuse: far too much assistance is available to you for it to be ignored. Let the revolution begin!

    With expanding health insurance coverage, innovative technologies, improved diagnostic acumen, and pharmaceutical additions combining to increase life expectancy, quality of life, and concomitant costs, the American health care system is under significant stress. However, it pales in comparison to the challenges faced by health care leaders during the American Civil War. As we approach the 150th anniversary of the conclusion of that war, it is appropriate to review key strategic health care decisions faced by military leaders during the Civil War and how their resultant outcomes may provide an appropriate perspective for today's leaders.

  4. Sex between men in the context of HIV: The AIDS 2008 Jonathan Mann Memorial Lecture in health and human rights

    PubMed Central

    2008-01-01

    Gay, bisexual, and other men who have sex with men (MSM) have been among the most affected populations by HIV since the AIDS pandemic was first identified in the 1980s. Evidence from a wide range of studies show that these men remain at the highest risk for HIV acquisition in both developed and developing countries, and that despite three decades of evidence of their vulnerability to HIV, they remain under-served and under-studied. Prevention strategies targeted to MSM are markedly under-funded in most countries, leading to limited access to health services including prevention, treatment, and care. We explore the global epidemic among MSM in 2008, the limited funding available globally to respond to these epidemics, and the human rights contexts and factors which drive HIV spread and limit HIV responses for these men. What do we mean by the term MSM? MSM is a construct from the 1990s that tries to capture behavior and not identity. It was crafted to avoid stigmatizing and culturally laden terms such as gay or bisexual, which do not capture the wide diversity of orientations, sexual practices, cultures, and contextual settings in which male same-sex behaviors occur, and where HIV transmission and acquisition risks are centered. MSM includes both gay and non-gay identified men, bisexual men, and MSM who identify themselves as heterosexuals. It also includes men engaging in "situational" sex between men, such as can occur in prisons, schools, militaries or other environments; and it includes male sex workers who may be of any orientation but are often at very high risk for HIV. MSM may include some biologically male transgender persons, though some do not identify as male. And MSM includes a wide array of traditional and local terms worldwide–with enormous cultural diversity in Asia, Africa, Latin America and elsewhere. We use the term MSM here at its most inclusive.

    Bistrow, Van

    What aren't we teaching about physics in the traditional lecture course? Plenty! By offering the Advanced Laboratory Course, we hope to shed light on the following questions: How do we develop a systematic process of doing experiments? How do we record procedures and results? How should we interpret theoretical concepts in the real world? What experimental and computational techniques are available for producing and analyzing data? With what degree of confidence can we trust our measurements and interpretations? How well does a theory represent physical reality? How do we collaborate with experimental partners? How do we best communicate our findings to others?These questions are of fundamental importance to experimental physics, yet are not generally addressed by reading textbooks, attending lectures or doing homework problems. Thus, to provide a more complete understanding of physics, we offer laboratory exercises as a supplement to the other modes of learning. The speaker will describe some examples of experiments, and outline the history, structure and student impressions of the Advanced Lab course at the University of Chicago Department of Physics.

  6. Fragmentation of armor piercing steel projectiles upon oblique perforation of steel plates

    Paris, V.; Weiss, A.; Vizel, A.; Ran, E.; Aizik, F.

    2012-08-01

    In this study, a constitutive strength and failure model for a steel core of a14.5 mm API projectile was developed. Dynamic response of a projectile steel core was described by the Johnson-Cook constitutive model combined with principal tensile stress spall model. In order to obtain the parameters required for numerical description of projectile core material behavior, a series of planar impact experiments was done. The parameters of the Johnson-Cook constitutive model were extracted by matching simulated and experimental velocity profiles of planar impact. A series of oblique ballistic experiments with x-ray monitoring was carried out to study the effect of obliquity angle and armor steel plate thickness on shattering behavior of the 14.5 mm API projectile. According to analysis of x-ray images the fragmentation level increases with both steel plate thickness and angle of inclination. The numerical modeling of the ballistic experiments was done using commercial finite element code, LS-DYNA. Dynamic response of high hardness (HH) armor steel was described using a modified Johnson-Cook strength and failure model. A series of simulations with various values of maximal principal tensile stress was run in order to capture the overall fracture behavior of the projectile's core. Reasonable agreement between simulated and x-ray failure pattern of projectile core has been observed.

    A review of results from the Uhuru satellite is presented. An intensive treatment of two subjects is given, rather than a broad review. First, Cyg X-1, a stellar X-ray source and a candidate for a black hole, is discussed; second, the X-ray source in the Perseus cluster of galaxies, which may be a cloud of hot intergalactic gas, is treated. In both cases, the train of logic used in establishing the nature of these objects is presented and evaluated. For both, while alternative explanations cannot be completely eliminated, they become more difficult to sustain when examined in detail, suggesting that the candidate explanations are more likely correct.

  9. Geology and metallization of the White River Area, King and Pierce Counties, Washington

    SciTech Connect

    McCulla, M.S.

    1986-01-01

    Bedrock of the White River area is dominated by Miocene age volcanics of andesite to rhyolite composition, which may be in part coeval with plutonic phases of the nearby 26 - 14 m.y. Tatoosh batholith. These volcanic rocks host two spatially distinct and gold-bearing epithermal deposits of the acid-sulfate type that are structurally, temporally, and genetically related to the formation and resurgent magmatic activity at the margin of an early Miocene caldera (22.6 - 19.1 m.y.). The age of hydrothermal activity is 20.4 +/- 0.1 m.y. based on UAr/TZAr analysis of hypogene alunite from the mineralized zone. Hydrothermal alteration and metallization of both deposits is chemically and mineralogically similar and consists of a central core of pervasive silicification that grades outward into zones of advanced argillic, argillic, and propylitic alteration. The largest of the two target areas is defined by a silica capping. Sulfur isotope analyses of cogenetic alunite-pyrite-enargite demonstrate a (34)S of +28.8 per thousand for the alunite-pyrite mineral pair. This large fractionation corroborates other field and mineralogic evidence for the hypogene origin of the alunite, and provides a geologically reasonable isotopic temperature estimate of 190 C for this epithermal deposit. Fold was introduced in at least 3 distinct episodes of structural-hydrothermal activity. The highest concentration of gold is within a zone measuring 1600 by 300-600 feet, and is localized in parts of the similar capping that contain outcrops of matrix-supported explosion breccias and veins having anomalous concentrations of up to 480 ppb Au, 13.7 ppm Ag, 1900 ppm As, 213 ppm Sb, 7.5 ppm Hg, and 10 ppm Mo.

    The Poverty Bay quadrangle lies near the center of the region?s intensively developing urban core. Less than 20 km north lies the city of Seattle; downtown Tacoma lies just southwest of the quadrangle. The map area expresses much of the tremendous range of Quaternary environments and deposits found throughout the central Puget Lowland. Much of the ground surface is mantled by a rolling surface of glacial till deposited during the last occupation of the Puget Lowland by a great continental ice sheet about 14,000 years ago. A complex sequence of older unconsolidated sediments extends far below sea level across most of the quadrangle, with no bedrock exposures at all.

    A prototype high frequency tuning fork oscillator has been fabricated and tested in an integrated surface micromachining technology. The amplifier circuitry uses a capacitive current detection method, which offers superior noise performance over previous resistive methods. The prototype device has an output frequency of 1.022 MHz and exhibits a noise floor of {minus}88 dBc/Hz at a distance of 500 Hz from the carrier. The dominant source of frequency instability is the nonlinearity introduced by the use of parallel plate actuation.

  2. Surface-water quality assessment of the Clover Creek basin, Pierce County, Washington, 1991-1992

    USGS Publications Warehouse

    McCarthy, K.A.

    1996-01-01

    Increasing urbanization in the 67-square-mile Clover Creek Basin has generated interest in the effects of land-use changes on local water quality. To investigate these effects, water-quality and streamflow data were collected from 19 surface-water sites in the basin over a 16-month period from January 1991 through April 1992. These data were used to understand the effects of surficial geology, land-use practices, and wastewater disposal practices on surface-water quality within the basin. The basin was divided into four drainage subbasins with dissimilar hydrogeologic, land-use, and water-quality characteristics. In the Upper Clover Creek subbasin, the high permeability of surficial geologic materials promotes infiltration of precipitation to ground water and thus attenuates the response of streams to rainfall. Significant interaction occurs between surface and ground water in this subbasin, and nitrate concentrations and specific conductance values, similar to those found historically in local ground water, indicate that sources such as subsurface waste-disposal systems and fertilizers are affecting surface- water quality in this area. In the Spanaway subbasin, the presence of Spanaway and Tule Lakes affects water quality, primarily because of the reduced velocity and long residence time of water in the lakes. Reduced water velocity and long residence times (1) cause settling of suspended materials, thereby reducing concentrations of suspended sediment and constituents that are bound to the sediment; (2) promote biological activity, which tends to trap nutrients in the lakes; and (3) allow dispersion to attenuate peaks in discharge and water-quality constituent concentrations. In the North Fork subbasin, the low permeability of surficial geologic materials and areas of intensive land development inhibit infiltration of precipitation and thus promote surface runoff to streams. Surface pathways provide little attenuation of storm runoff and result in rapid increases in stream discharge in response to rainfall. Substantial increases in concentrations of constituents associated with surface wash off, for example, suspended sediment, ammonia, phosphorus, and fecal coliform, also were observed in this subbasin during rainfall. In the Lower Clover Creek subbasin, which is the most downstream subbasin, stream-discharge and water-quality characteristics show the integrated effects of the entire basin. The data show that further characterization of local ground water and discharge from stormwater outfalls entering Clover Creek and its tributaries would be necessary to successfully apply a numerical water-quality model to the basin.

  3. Water quality in the lower Puyallup River valley and adjacent uplands, Pierce County, Washington

    USGS Publications Warehouse

    Ebbert, J.C.; Bortleson, Gilbert C.; Fuste, L.A.; Prych, E.A.

    1987-01-01

    The quality of most ground and surface water within and adjacent to the lower Puyallup River valley is suitable for most typical uses; however, some degradation of shallow groundwater quality has occurred. High concentrations of iron and manganese were found in groundwater, sampled at depths of < 40 ft, from wells tapping alluvial aquifers and in a few wells tapping deeper aquifers. Volatile and acid- and base/neutral-extractable organic compounds were not detected in either shallow or deep groundwater samples. The quality of shallow groundwater was generally poorer than that of deep water. Deep ground water (wells set below 100 ft) appears suitable as a supplementary water supply for fish-hatchery needs. Some degradation of water quality, was observed downstream from river mile 1.7 where a municipal wastewater-treatment plant discharges into the river. In the Puyallup River, the highest concentrations of most trace elements were found in bed sediments collected downstream from river mile 1.7. Median concentrations of arsenic, lead, and zinc were higher in bed sediments from small streams compared with those from the Puyallup River, possibly because the small stream drainages, which are almost entirely within developed areas, receive more urban runoff as a percentage of total flow. Total-recoverable trace-element concentrations exceeded water-quality criteria for acute toxicity in the Puyallup River and in some of the small streams. In most cases, high concentrations of total-recoverable trace elements occurred when suspended-sediment concentrations were high. Temperatures in all streams except Wapato Creek and Fife Dutch were within limits (18 C) for Washington State class A water. Minimum dissolved oxygen concentrations were relatively low at 5.6 and 2.0 mg/L, respectively, for Wapato Creek and Fife Dutch. The poorest surface-water quality, which can be characterized as generally unsuitable for fish, was in Fife Dutch, a manmade channel and therefore uncharacteristic of other small streams.

  8. Forces on surface-piercing vertical circular cylinder groups on flooding staircase

    NASA Astrophysics Data System (ADS)

    Jiang, Li-jie; Shao, Wei-yun; Zhu, David Z.; Sun, Zhi-lin

    2014-04-01

    Flooding into underground spaces has become a common threat and caused significant damages and casualties in the past decades. To improve the understanding of people walking through the flooding staircase, a 1:2-scale physical model of a staircase with rest platform was assembled. An instrument was developed to measure the hydrodynamic forces acting on individual vertical circular cylinders, as well as cylinder groups arranged side-by-side, in tandem and staggered cylinder arrays on the flooding staircase. The results show that the horizontal hydrodynamic force on a cylinder increases rapidly with the increasing of the inundated depth on the entrance of the staircase. With a side-by-side tight cylinder array, the force on the central cylinder is always larger than an isolated one. The force on the downstream cylinder in tandem cylinder array is always smaller. However, the drag coefficients of both cases are much larger than the corresponding ones in a horizontal bed channel. For the case of staggered cylinder array, the force on the downstream cylinder varies with the change of the transverse spacing and the longitudinal distance between cylinders.

  9. Piercing the water surface with a blade: Singularities of the contact line

    NASA Astrophysics Data System (ADS)

    Alimov, Mars M.; Kornev, Konstantin G.

    2016-01-01

    An external meniscus on a narrow blade with a slit-like cross section is studied using the hodograph formulation of the Laplace nonlinear equation of capillarity. On narrow blades, the menisci are mostly shaped by the wetting and capillary forces; gravity plays a secondary role. To describe a meniscus in this asymptotic case, the model of Alimov and Kornev ["Meniscus on a shaped fibre: Singularities and hodograph formulation," Proc. R. Soc. A 470, 20140113 (2014)] has been employed. It is shown that at the sharp edges of the blade, the contact line makes a jump. In the wetting case, the contact line sitting at each side of the blade is lifted above the points where the meniscus first meets the blade edges. In the non-wetting case, the contact line is lowered below these points. The contours of the constant height emanating from the blade edges generate unusual singularities with infinite curvatures at some points at the blade edges. The meniscus forms a unique surface made of two mirror-symmetric sheets fused together. Each sheet is supported by the contact line sitting at each side of the blade.

  12. Newspaper representations of mental illness and the impact of the reporting of "events" on social policy: the "framing" of Isabel Schwarz and Jonathan Zito.

    PubMed

    Paterson, B

    2006-06-01

    Concerns have been raised internationally about the role of the media in influencing public opinion and by implication, social policy on mental health issues. In particular, anxieties have been expressed that an "excessive" focus by the news media on violence in association with mental illness may reinforce pre-existing stereotypes and by escalating public concerns lead to the adoption of policies which place a high priority on the safety of the public. Such assertions are often contained in the numerous studies that record a seemingly disproportionate number of stories featuring violence in association with mental health. What is, however, almost invariably lacking is a developed theory of agency that explains how or why such depictions of mental illness might exert an influence on social policy. This paper critically examines the potential significance of the way in which responsibility for events is constructed for social policy by means of a discourse analysis, inspired by the genealogical work of Michel Foucault. It uses the device of "frames" originally developed by Goffman to explore the nature of newspaper coverage of two deaths to which causal responsibility for changes in the nature of English social policy in mental health has been attributed. Results presented suggest that attempts to assert a causal influence between media coverage and changes in the nature of social policy must engage with the question of agency.

These moths are placed within the subfamily Calpinae, whose other members are known to exhibit a broad range of feeding behaviors including those that can be considered 'piercers' of fruits or other hosts and 'tear feeders'. Here, we reconstruct a phylogenetic hypothesis of Calpinae using molecular data to test whether hematophagy in Calyptra arose from plant or animal-related behaviors. We use a Bayesian method of ancestral state reconstruction to determine the most likely feeding behaviors for the subtribes and genera within this lineage.

    The rpfF gene from Xylella fastidiosa, encoding the synthase for diffusible signal factor (DSF), was expressed in 'Freedom' grape to reduce the pathogen's growth and mobility within the plant. Symptoms in such plants were restricted to near the point of inoculation and incidence of disease was two- to fivefold lower than in the parental line. Both the longitudinal and lateral movement of X. fastidiosa in the xylem was also much lower. DSF was detected in both leaves and xylem sap of RpfF-expressing plants using biological sensors, and both 2-Z-tetradecenoic acid, previously identified as a component of X. fastidiosa DSF, and cis-11-methyl-2-dodecenoic acid were detected in xylem sap using electrospray ionization mass spectrometry. A higher proportion of X. fastidiosa cells adhered to xylem vessels of the RpfF-expressing line than parental 'Freedom' plants, reflecting a higher adhesiveness of the pathogen in the presence of DSF. Disease incidence in RpfF-expressing plants in field trials in which plants were either mechanically inoculated with X. fastidiosa or subjected to natural inoculation by sharpshooter vectors was two- to fourfold lower in than that of the parental line. The number of symptomatic leaves on infected shoots was reduced proportionally more than the incidence of infection, reflecting a decreased ability of X. fastidiosa to move within DSF-producing plants.

    The water-budget area received about 1,428,000 acre-feet or about 52 inches of precipitation per year (January 1, 2011, to December 31, 2012). About 41 percent of precipitation enters the groundwater system as recharge. Seven percent of this recharge is withdrawn from wells and the remainder leaves the groundwater system as discharge to rivers, discharge to springs, or submarine discharge to Puget Sound, or exits the study area through subsurface flow in the Green River valley.

    Xylella fastidiosa is a xylem-limited bacterium in plant hosts and causes Pierce’s disease (PD) of grapevines, which differ in susceptibility according to the Vitis species (spp.). In this work we compared X. fastidiosa biofilm formation and population dynamics when cultured in xylem saps from PD-susceptible and -resistant Vitis spp. under different conditions. Behaviors in a closed-culture system were compared to those in different sap-renewal cultures that would more closely mimic the physicochemical environment encountered in planta. Significant differences in biofilm formation and growth in saps from PD-susceptible and -resistant spp. were only observed using sap renewal culture. Compared to saps from susceptible V. vinifera, those from PD-resistant V. aestivalis supported lower titers of X. fastidiosa and less biofilm and V. champinii suppressed both growth and biofilm formation, behaviors which are correlated with disease susceptibility. Furthermore, in microfluidic chambers X. fastidiosa formed thick mature biofilm with three-dimensional (3-D) structures, such as pillars and mounds, in saps from all susceptible spp. In contrast, only small aggregates of various shapes were formed in saps from four out of five of the resistant spp.; sap from the resistant spp. V. mustangensis was an exception in that it also supported thick lawns of biofilm but not the above described 3-D structures typically seen in a mature biofilm from the susceptible saps. Our findings provide not only critical technical information for future bioassays, but also suggest further understanding of PD susceptibility. PMID:27508296

    In 2003, the Puget Sound Lidar Consortium obtained a lidar-derived digital elevation model (DEM) for the Puget Sound region including all of the Poverty Bay 7.5' quadrangle. For a brief description of lidar (LIght Detection And Ranging) and this data acquisition program, see Haugerud and others (2003). This new DEM has a horizontal resolution and accuracy of 6 ft (2 m) and vertical accuracy of approximately 1 ft (0.3 m). The greater resolution and accuracy of the lidar DEM have facilitated a new interpretation of the geology, especially the distribution and relative age of some surficial deposits.

    The American Lake Gardens site is on the National Priorities List. Two areas within the site are the areas of primary contamination; the northeast section's contamination is believed to have come from the closed landfill (now a golf course) on McChord AFB, and the southwest section's contamination from Fort Lewis. Both Fort Lewis and McChord AFB are NPL sites. The environmental contamination on-site consists of trans-1,2-dichloroethylene (530 ppb), trichloroethylene (260 ppb), methylene chloride (38 ppb), tetrachloroethylene (52 ppb), benzene (6 ppb), and 1,1,1-trichloroethane (18 ppb) in ground water. The site is considered to be of potential public health concern because of the risk to human health caused by the possibility of exposure to hazardous substances via ground water (from private wells still in use) and surface water.

    Nowadays the problem of design of durable ecologically friendly superhydrophobic surfaces is of great importance for science and technology. A recent paper in Applied Surface Science reports the method of fabricating the superhydrophobic metallic surfaces by infrared nanosecond laser surface texturing without using hydrophobic agents. Since this method of surface texturing can be considered as one of the most suitable for various industrial applications, the nature of superhydrophobic state of surfaces produced by laser texturing in the abovementioned paper deserves to be analyzed in detail. Authors of the commented paper attributed the change in wettability to the partial deoxidation of CuO into Cu2O on the surface during storage in atmosphere. However, such interpretation of the results contradicts to the basic notions in the theory of wetting and to more accurate and detailed data. In our Comment we discuss these contradictions point by point.

    The musculature of the male genitalia was reviewed for the tribe Xanthorhoini and related tribes (Lepidoptera, Geometridae, Larentiinae). The genitalia morphology of males of 11 species was discussed and illustrated, and nine paired and unpaired genital muscles identified. Muscles m1, m2(10), m5(7), m6(5), m7(6), m8(3) and m21 have similar position in all species considered in the paper. Comparative morphology of the male terminalia and position of extensors of the valvae m3(2) and flexors m4 confirmed the previously uncertain separation of Euphyiini and Scotopterygini. Cataclysmini share musculature characters with the tribe Xanthorhoini. The generic affiliation of Xanthorhoe biriviata (Borkhausen) is questionable considering an unusual location of muscles m4. Generally, the places of attachment of the muscles m3(2) and m4 to the sclerites afford valuable characters for the higher classification of this group.

    As part of the effort to assess seismic hazard in the Puget Sound region, we map fault scarps on Airborne Laser Swath Mapping (ALSM, an application of LiDAR) imagery (with 2.5-m elevation contours on 1:4,000-scale maps) and show field and laboratory data from backhoe trenches across the scarps that are being used to develop a latest Pleistocene and Holocene history of large earthquakes on the Tacoma fault. We supplement previous Tacoma fault paleoseismic studies with data from five trenches on the hanging wall of the fault. In a new trench across the Catfish Lake scarp, broad folding of more tightly folded glacial sediment does not predate 4.3 ka because detrital charcoal of this age was found in stream-channel sand in the trench beneath the crest of the scarp. A post-4.3-ka age for scarp folding is consistent with previously identified uplift across the fault during AD 770-1160. In the trench across the younger of the two Stansberry Lake scarps, six maximum 14C ages on detrital charcoal in pre-faulting B and C soil horizons and three minimum ages on a tree root in post-faulting colluvium, limit a single oblique-slip (right-lateral) surface faulting event to AD 410-990. Stratigraphy and sedimentary structures in the trench across the older scarp at the same site show eroded glacial sediments, probably cut by a meltwater channel, with no evidence of post-glacial deformation. At the northeast end of the Sunset Beach scarps, charcoal ages in two trenches across graben-forming scarps give a close maximum age of 1.3 ka for graben formation. The ages that best limit the time of faulting and folding in each of the trenches are consistent with the time of the large regional earthquake in southern Puget Sound about AD 900-930.

  9. MC 2: Constraining the Dark Matter Distribution of the Violent Merging Galaxy Cluster CIZA J2242.8+5301 by Piercing through the Milky Way

    The galaxy cluster CIZA J2242.8+5301 at z = 0.19 is a merging system with a prominent (~2 Mpc long) radio relic, which together with the morphology of the X-ray emission provides strong evidence for a violent collision along the north-south axis. We present our constraints on the dark matter distribution of this unusual system using Subaru and Canada-France-Hawaii Telescope imaging data. Measuring a high signal-to-noise ratio lensing signal from this cluster is potentially a challenging task because of its proximity to the Milky Way plane (|b| ~ 5°). We overcome this challenge with careful observation planning and systematics control, which enables us to successfully map the dark matter distribution of the cluster with high fidelity. The resulting mass map shows that the mass distribution of CIZA J2242.8+5301 is highly elongated along the north-south merger axis inferred from the orientation of the radio relics. Based on our mass reconstruction, we identify two sub-clusters, which coincide with the cluster galaxy distributions. We determine their masses using Markov Chain Monte Carlo analysis by simultaneously fitting two Navarro-Frenk-White halos without fixing their centroids. The resulting masses of the northern and southern systems are M200=11.0-3.2+3.7× 1014 M⊙ and 9.8-2.5+3.8× 1014 M⊙ , respectively, indicating that we are witnessing a post-collision of two giant systems of nearly equal mass. When the mass and galaxy centroids are compared in detail, we detect ~1' (~190 kpc) offsets in both northern and southern sub-clusters. After investigating the statistical significance of the offsets by bootstrapping both mass and galaxy centroids, we find that the galaxy luminosity-mass offset for the northern clump is statistically significant at the >~ 2σ level whereas the detection is only marginal for the southern sub-cluster in part because of a relatively large mass centroid error. We conclude that it is yet premature to uniquely attribute the galaxy-mass misalignment to self-interaction of dark matter and discuss caveats.

  10. Mid to late Devonian back-arc rift basins in the Brooks Range, AK, and across the Arctic: a possible paleogeographic piercing point for Arctic reconstructions

    NASA Astrophysics Data System (ADS)

    2013-12-01

    The westernmost Brooks Range, Alaska, is underlain by basement of probable Baltic or Timanian affinity (e.g. Miller et al., 2011; Amato et al., 2009), while the eastern Brooks Range is underlain by Laurentian affinity basement (e.g. Strauss et al., 2013). A post-Timanian and pre-Mississippian suture or contact is thus required based on continuity of late Devonian and younger strata across the Brooks Range (e.g. Dumoulin et al., 2002). This inferred juxtaposition has been proposed as the distal and diachronous (though possibly non-collisional) continuation of the Caledonian orogen (e.g. Moore et al., 2012) but the actual location and character of this suture within basement rocks of the Brooks Range remain speculative. New laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) U-Pb single grain detrital zircon (DZ) geochronology of basement rocks from the Cosmos Hills, Slate Creek, and Wiseman regions suggest that metamorphic rocks in these regions are Devonian, not pre-Devonian. New SHRIMP-RG analyses of the Kogoluktuk orthogneiss (Cosmos) (zircon: 383 Ma × 5 Ma, 2-sigma errors, consistent with Dillon et al. 1980) revealed no inherited cores from which to infer basement affinity. DZ spectra from metasedimentary and metavolcanic wall rock contain youngest detrital zircon populations with ages (390 Ma) just barely older than the cross-cutting intrusive age, providing tight bracketing of depositional age. These zircon ages are noticeably younger than Caledonian magmatic ages (430-420 Ma) suggesting deposition in a volcanically and tectonically active setting (likely extensional) as originally suggested by Hitzman et al (1986). Zircon spectra (Cosmos) contain notable amounts of "Timanian" age zircons (c. 700-550 Ma), and a spread of zircons from 1-2 Ga (including 1.5-1.6 Ga ages of the Laurentian "magmatic gap', e.g. Grove et al. 2008) more typical of derivation from Baltic rather than Laurentian sources. East in the Wiseman and Slate Creek localities, the detrital signature becomes characteristically Laurentian, with a notable absence of Timanian and "magmatic gap" ages. A youngest age population of 390 Ma still provides a maximum depositional age, but minimum age is poorly constrained. The coarse and feldspathic nature of many of these intercalated volcanic and clastic sequences suggests a proximal provenance, thus serving as a proxy for local pre-Devonian basement ages and affinity. We might, therefore, infer a non-Laurentian basement for the AACM at least as far east as the Cosmos Hills but not further east than the Wiseman region. These Devonian-age volcanic/rift basins may be related to slab roll-back and induced backarc rifting that occurred obliquely across a 'Caledonian' suture, possibly in response to global plate re-organization. Rifting, accompanied by bimodal volcanism (the Ambler Sequence), may have aided the removal and translation of peri-Baltic terranes to a position outboard of the proto-Cordilleran margin ('Northwestern Passage' of Colpron & Nelson, 2009). Further correlations might be drawn with the Sakmarian-Magnitogorsk arcs of the pre-Uralian margin of Europe. These Devonian backarc rift sequences - more widespread than previously thought - may serve as critical additional tie-points for paleogeographic reconstructions of the Arctic.

    Extreme rituals (body-piercing, fire-walking, etc.) are anecdotally associated with altered states of consciousness-subjective alterations of ordinary mental functioning (Ward, 1984)-but empirical evidence of altered states using both direct and indirect measures during extreme rituals in naturalistic settings is limited. Participants in the "Dance of Souls", a 3.5-hour event during which participants received temporary piercings with hooks or weights attached to the piercings and danced to music provided by drummers, responded to measures of two altered states of consciousness. Participants also completed measures of positive and negative affect, salivary cortisol (a hormone associated with stress), self-reported stress, sexual arousal, and intimacy. Both pierced participants (pierced dancers) and non-pierced participants (piercers, piercing assistants, observers, drummers, and event leaders) showed evidence of altered states aligned with transient hypofrontality (Dietrich, 2003; measured with a Stroop test) and flow (Csikszentmihalyi, 1990; Csikszentmihalyi & Csikszentmihalyi, 1990; measured with the Flow State Scale). Both pierced and non-pierced participants also reported decreases in negative affect and psychological stress and increases in intimacy from before to after the ritual. Pierced and non-pierced participants showed different physiological reactions, however, with pierced participants showing increases in cortisol and non-pierced participants showing decreases from before to during the ritual. Overall, the ritual appeared to induce different physiological effects but similar psychological effects in focal ritual participants (i.e., pierced dancers) and in participants adopting other roles.

  6. Altered States of Consciousness during an Extreme Ritual

    Extreme rituals (body-piercing, fire-walking, etc.) are anecdotally associated with altered states of consciousness—subjective alterations of ordinary mental functioning (Ward, 1984)—but empirical evidence of altered states using both direct and indirect measures during extreme rituals in naturalistic settings is limited. Participants in the “Dance of Souls”, a 3.5-hour event during which participants received temporary piercings with hooks or weights attached to the piercings and danced to music provided by drummers, responded to measures of two altered states of consciousness. Participants also completed measures of positive and negative affect, salivary cortisol (a hormone associated with stress), self-reported stress, sexual arousal, and intimacy. Both pierced participants (pierced dancers) and non-pierced participants (piercers, piercing assistants, observers, drummers, and event leaders) showed evidence of altered states aligned with transient hypofrontality (Dietrich, 2003; measured with a Stroop test) and flow (Csikszentmihalyi, 1990; Csikszentmihalyi & Csikszentmihalyi, 1990; measured with the Flow State Scale). Both pierced and non-pierced participants also reported decreases in negative affect and psychological stress and increases in intimacy from before to after the ritual. Pierced and non-pierced participants showed different physiological reactions, however, with pierced participants showing increases in cortisol and non-pierced participants showing decreases from before to during the ritual. Overall, the ritual appeared to induce different physiological effects but similar psychological effects in focal ritual participants (i.e., pierced dancers) and in participants adopting other roles.

  8. Gamma-ray exposure hazard due to stowage of M-774 APFSDS (Armour-piercing fin-stabilized discarding-sabot) rounds in a Leopard C-1 main battle tank. Technical note

    SciTech Connect

    Robitaille, H.A.

    1983-09-01

    The M-744 APFSDS anti-tank round contains a depleted-uranium penetrator of 3.4 kgram mass. Since depleted uranium is naturally radioactive, the storage of a substantial number of these rounds inside a Leopard C-1 main battle tank creates a gamma radiation field within the vehicle. Gamma-ray exposure rates have been measured using a sodium-iodide spectrometer at each of the four crew-member locations and for two turret orientations, with 59 rounds stowed in the vehicle. In all cases the measured gamma-ray dose rates were less than a maximum of 0.17 millirad per hour observed at the loader's position. Assuming the loader spent an entire week (168 hours) at his station, his integrated dose would amount to 29 mRad - approximately a factor of 4 lower than the maximum currently allowed by Canadian Forces regulations. It is therefore concluded that the M774 round does not represent a significant gamma radiation hazard to Leopard C1 crewmembers.

  17. The Cognitive Processes Underlying Event-Based Prospective Memory In School Age Children and Young Adults: A Formal Model-Based Study

    PubMed Central

    Smith, Rebekah E.; Bayen, Ute Johanna; Martin, Claudia

    2010-01-01

    Fifty 7-year-olds (29 female), 53 10-year-olds (29 female), and 36 young adults (19 female), performed a computerized event-based prospective memory task. All three groups differed significantly in prospective memory performance with adults showing the best performance and 7-year-olds the poorest performance. We used a formal multinomial process tree model of event-based prospective memory to decompose age differences in cognitive processes that jointly contribute to prospective memory performance. The formal modeling results demonstrated that adults differed significantly from the 7-year-olds and 10-year-olds on both the prospective component and the retrospective component of the task. The 7-year-olds and 10-year-olds differed only in the ability to recognize prospective memory target events. The prospective memory task imposed a cost to ongoing activities in all three age groups.
