Detection of specific features in the functioning of a system for the anti-corrosion protection of underground pipelines at oil and gas enterprises using neural networks

The information was reviewed to orderly arrange theoretical provisions and to devise practical recommendations for the diagnostic examination of a system for the anti-corrosion protection of underground metal oil and gas pipelines. A set of informative parameters for modeling functional relations and determining polarization potential in the system "underground metal structure – cathodic protection plant" was formed. It was proposed to apply the algorithm of prediction of corrosive current, the approach of non-linear programming, as well as the neural network, including the corresponding methods of learning, for a pipeline section, taking into account the polarization potential on the outer surface. The test set to evaluate the effectiveness of a neural network was formed. The above-mentioned information is essential for the improvement of the equipment of distant control of metal structures of oil and gas enterprises, that is, the procedures for correct measuring and evaluating direct and alternating voltages, as well as polarization potential in a pipeline. The methods and algorithms of neural networks, which are used to control the anticorrosive protection of underground pipelines, were explored. The study of the effectiveness of artificial neural networks, specifically, a two-layer network of direct propagation with the function of prediction of the resource of metal pipes. Using the polarization potential, we detected the capability of neural networks to perform inaccessible for conventional mathematics operations of processing, comparison, classification of images, capability of self-learning and self-organization relative to underground pipelines. The qualimetric quality criterion for a pipeline section, taking into consideration the optimal range of polarization potential was improved. We developed the method for prediction of the polarization potential of a cathodic protection plant and transitional specific resistance of the insulating coating on the surface of an underground metal structure using a neural network. Taking into consideration the results of analysis of polarization potential and transitional specific resistance, the methodology of formation of information support for procedures of degradation of anticorrosive dielectric coating and metal on the outer surface of an underground metal structure, as well as for predicting its resource, was designed
The impact of cyclophosphamide on menstruation and pregnancy in women with rheumatologic disease

Background While cyclophosphamide (CYC) can save the life of a young woman with severe rheumatologic disease, it may lead to the long-term side-effects of infertility and premature menopause. We compared the reproductive health histories of young women with rheumatologic disease with and without prior CYC exposure to identify the impact of this medication on this important component of health. Methods This research includes a case-series study of women diagnosed with SLE, vasculitis, and scleroderma prior to age 35. Each patient completed a questionnaire about desired childbearing, menstrual regularity, infertility, and pregnancy history. Women with prior CYC therapy were queried about the use of gonadotropin-releasing hormone agonists (GnRH-a) for fertility preservation. The responses to this questionnaire were compared for women with and without CYC exposure. Results Of the 43 participants, 23 had prior CYC exposure and 20 were CYC naïve. The current age of these groups was similar (average age 32), but women with prior CYC were four years younger at diagnosis than women without CYC. More women with prior CYC had cessation of menses in the year prior to the study (30.4% vs 0%, p < 0.05). Of the women with prior CYC exposure, those with loss of menses were older at study enrollment, older at CYC treatment, and had a higher cumulative CYC dose than those with preserved menstruation. While more women with GnRH-a co-therapy during CYC had maintained menses, this difference did not reach statistical significance. Women with prior CYC without GnRH-a co-therapy had a higher frequency of nulliparity and had greater trouble conceiving than women with GnRH-a co-therapy. Few pregnancies were conceived following CYC exposure and all resulted in elective termination, miscarriage, or preterm birth. Conclusion In this cohort of young women with rheumatologic disease, more women with prior CYC than without had amenorrhea, nulliparity, and infertility. GnRH-a co-therapy may prevent these adverse effects of CYC.
Evidence that the COMTVal158Met polymorphism moderates sensitivity to stress in psychosis: An experience‐sampling study

Gene–environment interactions involving the catechol‐O‐methyltransferase Val158Met polymorphism (COMTVal158Met) have been implicated in the causation of psychosis. Evidence from general population studies suggests that Met/Met subjects are sensitive to stress, a trait associated with psychosis. We hypothesized that the Met allele would moderate the effects of stress on negative affect (NA) in controls, and on NA and psychosis in patients with a psychotic disorder. Thirty‐one patients with a psychotic disorder and comorbid cannabis misuse and 25 healthy cannabis users were studied with the experience sampling method (ESM), a structured diary technique assessing current context and emotional and psychotic experiences in daily life. A significant interaction between COMTVal158Met genotype and ESM stress in the model of NA was found for patients (interaction χ2 = 7.4, P = 0.02), but not for controls (interaction χ2 = 3.8, P = 0.15). In the model of ESM psychosis, a significant interaction between COMTVal158Met genotype and ESM stress was also apparent (interaction χ2 = 11.6, P < 0.01), with Met/Met patients showing the largest increase in psychotic experiences as well as NA in reaction to ESM stress. The findings suggest that the COMTVal158Met polymorphism moderates affective and psychotic responses to stress in patients with psychosis, providing evidence for gene–environment interaction mechanisms in the formation of psychotic symptoms. © 2007 Wiley‐Liss, Inc.
Tensile Lattice Strain Accelerates Oxygen Surface Exchange and Diffusion in La1–xSrxCoO3−δ Thin Films

The influence of lattice strain on the oxygen exchange kinetics and diffusion in oxides was investigated on (100) epitaxial La1–xSrxCoO3−δ (LSC) thin films grown by pulsed laser deposition. Planar tensile and compressively strained LSC films were obtained on single-crystalline SrTiO3 and LaAlO3. 18O isotope exchange depth profiling with ToF-SIMS was employed to simultaneously measure the tracer surface exchange coefficient k* and the tracer diffusion coefficient D* in the temperature range 280–475 °C. In accordance with recent theoretical findings, much faster surface exchange (∼4 times) and diffusion (∼10 times) were observed for the tensile strained films compared to the compressively strained films in the entire temperature range. The same strain effect—tensile strain leading to higher k* and D*—was found for different LSC compositions (x = 0.2 and x = 0.4) and for surface-etched films. The temperature dependence of k* and D* is discussed with respect to the contributions of strain states, formation enthalpy of oxygen vacancies, and vacancy mobility at different temperatures. Our findings point toward the control of oxygen surface exchange and diffusion kinetics by means of lattice strain in existing mixed conducting oxides for energy conversion applications.
Guidelines on the laboratory aspects of assays used in haemostasis and thrombosis

Publications known to the writing group were supplemented with additional papers identified by searching Medline/PubMed for publications in the last 12 years using keywords: coagulation assays, amidolytic assays, haemostasis assays, and thrombophilia testing, in core clinical journals and English language. Additional relevant articles were identified by screening reference lists and by publications known to the writing group. The writing group produced the draft guideline which was subsequently revised by consensus by members
A Study of Depression and Obsessionality in Dysmorphophobic and Psoriatic Patients

Summary Measures of depression and obsessionality were made in patients with dysmorphophobia, psoriasis and control subjects. The depression score distinguished all three groups. Patients with dysmorphophobia had significantly higher scores compared to the patients with psoriasis, who in turn had significantly higher scores compared to a control group. Patients with dysmorphophobia and psoriasis had equally elevated obsessional symptom scores compared to controls. It is unlikely, therefore, that dysmorphophobic symptoms are due to an obsessional state. Depression, however, was found to be an important clinical feature of dysmorphophobia.
Radial permeability of the hybrid pine (Pinus elliottii × Pinus caribaea) in Australia

The radial permeability (gas and liquid) of the hybrid pine (Pinus elliottii var. elliottii [PEE] × Pinus caribaea var. hondurensis [PCH]) was investigated for wood samples collected from 30 trees that were 19 years of age and represented various genotypes and stocking rates. The PEE × PCH hybrid is now a very important resource for the Australian forestry industry, producing logs used to manufacture a diverse array of wood products. The permeability of wood influences many important wood properties and industrial processes. For all data combined from all radial sampling positions, there was no significant effect of genotype and stocking rate on radial permeability. Both gas and liquid permeability increased from pith to bark positions within the tree. Conversely, resin content decreased from pith to bark positions. Gas and liquid permeability were significantly positively correlated, and a highly significant negative relationship was also found between permeability (gas and liquid) and resin content.
Substantial sulfatide deficiency and ceramide elevation in very early Alzheimer's disease: potential role in disease pathogenesis

In addition to pathology in the gray matter, there are also abnormalities in the white matter in Alzheimer's disease (AD). Sulfatide species are a class of myelin‐specific sphingolipids and are involved in certain diseases of the central nervous system. To assess whether sulfatide content in gray and white matter in human subjects is associated with both the presence of Alzheimer's disease (AD) pathology as well as the stage of dementia, we analyzed the sulfatide content of brain tissue lipid extracts by electrospray ionization mass spectrometry from 22 subjects whose cognitive status at time of death varied from no dementia to very severe dementia. All subjects with dementia had AD pathology. The results demonstrate that: (i) sulfatides were depleted up to 93% in gray matter and up to 58% in white matter from all examined brain regions from AD subjects with very mild dementia, whereas all other major classes of lipid (except plasmalogen) in these subjects were not altered in comparison to those from age‐matched subjects with no dementia; (ii) there was no apparent deficiency in the biosynthesis of sulfatides in very mild AD subjects as characterized by the examination of galactocerebroside sulfotransferase activities in post‐mortem brain tissues; (iii) the content of ceramides (a class of potential degradation products of sulfatides) was elevated more than three‐fold in white matter and peaked at the stage of very mild dementia. The findings demonstrate that a marked decrease in sulfatides is associated with AD pathology even in subjects with very mild dementia and that these changes may be linked with early events in the pathological process of AD.
Mucho camino: the experiences of two undocumented Mexican mothers participating in their child's early intervention program.

OBJECTIVE This study describes the experiences of two mothers of Mexican origin who are immigrants living under undocumented status in the United States and who participated in their children's early intervention programs. METHOD In-depth interviews, archival data, and participant observation conducted with two mothers of children with special needs provided data for this case study design research. A phenomenological analytical approach and qualitative data analysis software were employed to gain understandings particular to each family's experience. RESULTS These families share similar experiences and interactions with many other families in the United States who live within the context of having a child with a disabling condition. Constraints on family functioning related to the families' status of undocumented immigration included: mothers as active participants in their children's early intervention programs, mothers' understanding of their children, mothers' communication with service providers, and life as an immigrant family of Mexican origin living under undocumented status. CONCLUSIONS The examination of how these mothers negotiated family life while participating in their child's early intervention program provides an appreciation for how these families view the long road--"mucho camino"--involved in achieving their family's well-being.
Caring for Children With Autism in an Emergency Department Setting

Objective Patients with autism spectrum disorder (ASD) and other developmental delays represent a unique patient population. We described a cohort of children with ASD cared for in an emergency department (ED) setting and the specific health care resources used for their care. Methods This is an observational study of consecutive children (<18 years) with ASD presenting for ED care. Comparisons of interest were evaluated using Wilcoxon rank sum and χ2 tests. Odds ratios (ORs) are reported with 95% confidence intervals (CIs). Results There were 238 ED visits over a 9-month period among 175 children. Median age was 9 years, and 62% were male. Reasons for ED visit were medical (51%), psychiatric (18%), injury/assault/trauma (16%), neurological (11%), and procedure related (4%.) Children with psychiatric complaints had longer lengths of stay than those with other chief complaints (P < 0.0001; OR, 5.8; CI, 2.8–11.9) and were more likely to have urine (OR, 8.5; CI, 3.9–18.3) and blood work ordered (OR, 2.5; CI, 1.2–4.9) and less likely to have x-rays ordered (OR, 0.10; CI, 0.02–0.44). Eighteen (8%) children received sedation. None required physical restraint. A total of 30% were admitted to the hospital. Those with psychiatric complaints were more likely to be admitted (54.8% vs 24.5%; OR, 3.7; CI, 1.9–7.4) than those with other chief complaints. Conclusions The care for children with ASD varied with age and health care issues. There was a high prevalence of psychiatric complaints, and many of these children were boarded in the ED waiting for an inpatient psychiatric bed. Those with psychiatric complaints were more likely to have multiple tests ordered and were more likely to be admitted.
Paediatric Femoral Neck Fracture: Experience of Management of our Patients and a Review of the Literature

Background: Femoral neck fractures are rare injuries in children, but their high incidence of long term complications make them an important clinical entity. The aim of this retrospective study was to analyze the clinical outcomes of paediatric femoral neck fractures that we managed over a 5-year period. Methods: The study included 4 children (2 boys and 2 girls) who sustained femoral neck fractures and completed a minimum follow-up of two years. All The children had operative management either by open reduction and internal fixation (ORIF), or closed reduction and internal fixation (CRIF). The outcomes were analyzed using Ratliff criteria and record of complications was kept for all patients. Results: The mean age of included patients was 11 years (range, 3 to 16 years). Based on Delbet’s classification, there were no types I (transepiphyseal) and IV (intertrochanteric), 3 type II and 1 type III. A satisfactory outcome was obtained in all 4 (100%) children even in a child who had cut out of the screws post-operative day 10. Conclusion: Despite a small series of internal fixation for paediatric hip fractures, we had encouraging outcomes with no avascular necrosis, no limb length discrepancy or non-union after a minimum followup of two years.
Semantically based reclassification of Danish land-use and land-cover information

In recent years, the availability of georeferenced data has increased substantially, as have the number of producers and users of this information. As a consequence, there is a growing need for harmonization of data, not least in its classification descriptions. Unfortunately, inadequate metadata hampers understanding of how data sets are produced and what data classes represent. This study describes how five different categorical geodata sets for Denmark, ranging from habitat registrations through maps of agricultural land use to national topographic data, are integrated and how the integrated data set is reclassified to land-use and land-cover classes. All five data sets differ with respect to data acquisition, and description and classification methodologies, and none of the data distinguish between land use and land cover. The purpose of the reclassification was to produce maps of land use and land cover, with classes being compatible with the land cover classification system (LCCS) from the Food and Agriculture Organization of the United Nations. We identified land-cover and land-use classes from the LCCS that matched Danish conditions and cross-tabulated those classes with classes from the integrated Danish data set. Based on the semantic meaning of the class names from the integrated data set, we used heuristic associational knowledge to estimate their membership in the land-use and land-cover classes. The results are three land-use maps and five land-cover maps, indicating qualitative estimates of the presence of land-cover classes measured on an ordinal scale.
X-linked H3K27me3 demethylase Utx is required for embryonic development in a sex-specific manner

Embryogenesis requires the timely and coordinated activation of developmental regulators. It has been suggested that the recently discovered class of histone demethylases (UTX and JMJD3) that specifically target the repressive H3K27me3 modification play an important role in the activation of “bivalent” genes in response to specific developmental cues. To determine the requirements for UTX in pluripotency and development, we have generated Utx-null ES cells and mutant mice. The loss of UTX had a profound effect during embryogenesis. Utx-null embryos had reduced somite counts, neural tube closure defects and heart malformation that presented between E9.5 and E13.5. Unexpectedly, homozygous mutant female embryos were more severely affected than hemizygous mutant male embryos. In fact, we observed the survival of a subset of UTX-deficient males that were smaller in size and had reduced lifespan. Interestingly, these animals were fertile with normal spermatogenesis. Consistent with a midgestation lethality, UTX-null male and female ES cells gave rise to all three germ layers in teratoma assays, though sex-specific differences could be observed in the activation of developmental regulators in embryoid body assays. Lastly, ChIP-seq analysis revealed an increase in H3K27me3 in Utx-null male ES cells. In summary, our data demonstrate sex-specific requirements for this X-linked gene while suggesting a role for UTY during development.
Automatic feature extraction from front and side images

This paper presents a systematic method to detect feature points on the silhouette of human body from front and side images. Based on the correspondence between the coordinates and the eight numbering system of chain codes, the codes that depicted at 90 degree angle were taken as corner points. The system then connects the other associated points horizontally and vertically. Thus, the human landmark positions of head, neck, shoulder, chest, waist, hip, thigh, knee, shank, ankle, and foot can be identified by the relationship between two correlative points. A total of 55 feature points and 26 body measurements can be extracted automatically. The method has been tested on four human subjects and all were correctly extracted.
No association of C‐1019G promoter polymorphism of 5‐HT1A receptor gene with migraine

It is well known that migraine has a strong genetic component, although the type and number of genes involved remains unclear. There is evidence to suggest that serotonin‐related genes may be involved in the pathogenesis of migraine. To investigate whether the 5‐HT1A receptor gene contributes to the risk of migraine we performed an association study of C‐1019G promoter polymorphism of the gene in 102 migraineurs and 93 controls. Subjects were of Han Chinese origin. No significant differences in allele (P = 0.82) or genotype frequencies (P = 0.71) were seen in migraineurs compared with the controls. When migraine with aura, without aura, with family history, without family history were analyzed separately, the frequencies did not vary significantly. Our results suggest that C‐1019G in 5‐HT1A is not a major genetic risk factor for migraine.
Effects of fruit zone leaf removal on the concentrations of phenolic and organic acids in Istrian Malvasia grape juice and wine.

Summary Phenolic acids, represented by hydroxycinnamic and hydroxybenzoic acids and their derivatives, are the most abundant phenolic compounds in grape juice and wine of white grapevine cultivars. The effects of fruit zone leaf removal on the concentration of hydroxycinnamic, hydroxybenzoic and organic acids of cv. Istrian Malvasia grape juice and wine are investigated in this study. Fruit zone leaf removal was applied at three different phenological stages: before blooming, at berry set and at veraison. Control treatment without leaf removal was also included. At veraison two intensities of leaf removal were applied. Phenolic and organic acids were identified and quantified using high-performance liquid chromatography. Juice samples from the grapes treated at the stages before blooming and berry set had the lowest concentrations of tartaric acid and the highest concentrations of malic acid, while juices from veraison stage treatments had the lowest concentrations of malic acid and the highest concentrations of tartaric acid. Before blooming treatment significantly lowered the concentration of all hydroxycinnamic and hydroxybenzoic acids in grape juice in comparison with other investigated treatments, which did not affect the concentration of total hydroxycinnamic acids considerably. The concentration of hydroxybenzoic acids in grape juice was lower in veraison treatments in comparison with berry set and control treatments. The concentrations of hydroxycinnamic, hydroxybenzoic and organic acids in wine followed the same trends as observed in grape juice. It is concluded that the concentration of phenolic and organic acids in grape juice and wine of white grapevine cultivars can be managed with the timing of fruit zone leaf removal according to the desired wine style.
