Relationship between sulfur deficiency in oilseed rape ( Brassica napus L . ) and its attractiveness for honeybees

Oilseed rape showing macroscopic symptoms of sulfur deficiency influences the behavior of honeybees, something that has been observed repeatedly in production fields. The symptomatology of sulfur deficiency in cruciferous crops is characteristic during the whole vegetation period. The peculiarity of sulfur deficiency symptoms during flowering depends on the moment when sulfur becomes a limiting factor. An early appearance of sulfur deficiency is regularly related to the change of the petal color from bright to pale yellow, or even white petals. At the same time, the petals are modified in size and shape. By comparison, a late occurrence of sulfur deficiency usually results in the change of color mentioned earlier, while other morphological parameters are not affected. It was the aim of this paper firstly to provide a condensed description of sulfur deficiency symptoms in oilseed rape during the vegetation period, secondly to determine the influence of the sulfur supply on morphological characteristic of oilseed rape petals, and thirdly to present for the first time data about the attractiveness of flowering oilseed rape for honey bees in relation to the S supply.
Quality of life response to resistive airflow training in patients with chronic obstructive pulmonary disease

This study was conducted to determine the quality of life response to resistive airflow training in patients with chronic obstructive disease. Sixty male patients were diagnosed clinically according to GOLD 2016 have moderate (GOLD 2) COPD with age ranged from 45-50 years enrolled in the study for twelve weeks. They were chosen from outpatient clinic of El-Sahel Teaching Hospital and were assigned into two groups equal in numbers. Both groups received traditional chest physical therapy (relaxed positions, diaphragmatic breathing, pursed lip breathing and postural drainage), while in program of the study group resistive airflow training using expand-a-lung was added. The 6MWT (walking distance and SPO2), and HRQL were assessed for both groups before and after 12 weeks of training. There was significant increase in results of 6MWT (walking distance 91.21%↑ and SPO2 4.34%↑), and significant decrease in the HRQL 75%↓ for the study group when compared with the control group . Resistive airflow training with expand-a-lung is an effective rehabilitative method for COPD patients in combination with traditional chest physical therapy improves HRQL, walking distances, peripheral oxygen saturation.
Measuring the Nonmarket Value of Massachusetts Agricultural Land: A Case Study

Agricultural land provides a variety of " nonmarket" services to the Commonwealth, including wildlife habitat, scenic vistas, and recreation . This study utilizes an iterative bidding game to estimate willingness-to-pay of residents of three central Massachusetts counties to preserve state agricultural land. Through the use of these data, estimates of the value of these nonmarket amenities are derived so that a fuUer measure of the value of agricultural land can be obtained. This information may be useful to policy makers administering such programs as the Agricultural Preservation Restriction Act (Chapter 780) which are designed to arrest the conversion of Massachusetts farmland to urban uses.
Theory of stellar convection - II. First stellar models

We present here the first stellar models on the Hertzsprung-Russell diagram, in which convection is treated according to the new scale-free convection theory (SFC theory) by Pasetto et al. The aim is to compare the results of the new theory with those from the classical, calibrated mixing-length (ML) theory to examine differences and similarities. We integrate the equations describing the structure of the atmosphere from the stellar surface down to a few per cent of the stellar mass using both ML theory and SFC theory. The key temperature over pressure gradients, the energy fluxes, and the extension of the convective zones are compared in both theories. The analysis is first made for the Sun and then extended to other stars of different mass and evolutionary stage. The results are adequate: The SFC theory yields convective zones, temperature gradients ∇ and ∇e, and energy fluxes that are very similar to those derived from the 'calibrated' MT theory for main-sequence stars. We conclude that the old scale dependent ML theory can now be replaced with a self-consistent scale-free theory able to predict correct results, as it is more physically grounded than the ML theory. Fundamentally, the SFC theory offers a deeper insight of the underlying physics than numerical simulations.
Accounting for Heterogeneity of Public Lands in Hedonic Property Models

Open space lands, national forests in particular, are usually treated as homogeneous entities in hedonic price studies. Failure to account for the heterogeneous nature of public open spaces may result in inappropriate inferences about the benefits of proximate location to such lands. In this study the hedonic price method is used to estimate the marginal values for proximity to the Pike National Forest. The results indicate that specifying the forest as homogeneous overstates the benefits for homes within two miles relative to specifying the forest based on land use characteristics, because the significant negative effect from noise-intensive activities is omitted.

Diagnostic value of growth differentiation factor-15 and β2-microglobulin in children with congenital heart disease combined with chronic heart failure and its relationship with cardiac function.

OBJECTIVE This study aimed to investigate the diagnostic value of growth differentiation factor-15 (GDF-15) and β2-microglobulin (β2-MG) in infants with congenital heart disease (CHD) combined with chronic heart failure and its relationship with cardiac function. PATIENTS AND METHODS A total of 100 cases of infants diagnosed with CHD combined with chronic heart failure in our hospital from July 2015 to July 2018 were selected as the experimental group, and 80 cases of healthy subjects underwent health examination in our hospital during the same period were selected as the control group. The levels of serum GDF-15 and β2-MG and LVEF index of the two groups were compared. The correlation analysis of GDF-15 and β2-MG levels and cardiac function classification was conducted. The diagnostic value of GDF-15 and β2-MG was analyzed by ROC curve. RESULTS The levels of GDF-15 and β2-MG were significantly higher in severe and moderate heart failure groups than those in mild heart failure group, and the levels were significantly higher in severe heart failure group than those in moderate heart failure group (p<0.001). Levels of GDF-15 and β2-MG in the experimental group were significantly higher than those in the control group (p<0.001) and the LVEF index in the experimental group was significantly lower than that in the control group (p<0.001). There was a positive correlation between levels of GDF-15 and β2-MG and the severity of heart failure. The sensitivity, specificity, and AUC of GDF-15 alone in diagnosis of CHD combined with chronic heart failure were respectively 91.25%, 74.00% and 0.821, those of β2-MG alone were 82.50%, 62.00% and 0.819, and those of GDF-15 combined with β2-MG were 82.50%, 82.00% and 0.888. In the prognosis, the sensitivity of GDF-15 and β2-MG was respectively 91.30%, 56.52%, specificity was 62.96%, 94.44%, and AUC was 0.806, 0.817. CONCLUSIONS Levels of GDF-15 and β2-MG are positively correlated with the severity of cardiac function, which can be used as an ideal indicator for early diagnosis of CHD combined with chronic heart failure, as well as a clinical indicator to judge the condition.
Cell Motility and Cancer

Cell migration is an essential systemic behavior, tightly regulated, of all living cells endowed with directional motility that is involved in the major developmental stages of all complex organisms such as morphogenesis, embryogenesis, organogenesis, adult tissue remodeling, wound healing, immunological cell activities, angiogenesis, tissue repair, cell differentiation, tissue regeneration as well as in a myriad of pathological conditions. However, how cells efficiently regulate their locomotion movements is still unclear. Since migration is also a crucial issue in cancer development, the goal of this narrative is to show the connection between basic findings in cell locomotion of unicellular eukaryotic organisms and the regulatory mechanisms of cell migration necessary for tumor invasion and metastases. More specifically, the review focuses on three main issues, (i) the regulation of the locomotion system in unicellular eukaryotic organisms and human cells, (ii) how the nucleus does not significantly affect the migratory trajectories of cells in two-dimension (2D) surfaces and (iii) the conditioned behavior detected in single cells as a primitive form of learning and adaptation to different contexts during cell migration. New findings in the control of cell motility both in unicellular organisms and mammalian cells open up a new framework in the understanding of the complex processes involved in systemic cellular locomotion and adaptation of a wide spectrum of diseases with high impact in the society such as cancer.
Collecting the Contemporary in the Imagined City

textabstractAbstract: Collecting the contemporary is hot. More and more cultural museums look beyond their walls and go out into the street searching for contemporariness. This transformation towards an open and audience-centred institution is still far from complete. Many museums face certain obstacles and issues on this journey. In my talk I would like to focus on three of these issues, seen from the perspective of a cultural scientist. The talk ends by discussing the concept of the Imagined City.
Functional morphology of antennae and sensilla of Hippodamia variegata (Coleoptera: Coccinellidae)

The lady beetle Hippodamia variegata is an important biocontrol agent of many aphids. In this study, the fine morphology of antennae as well as the typology, morphology and distribution of antennal sensilla were comprehensively examined by scanning electron microscopy. The antennal morphology of female and male are similar and consist of the scape, pedicel, and nine flagellomeres. No significant difference was detected in the length of each segment between two sexes, while the male antennae are much stronger than females. In total, six types of sensilla can be defined on antenna, including Böhm bristle, sensilla chaetica (with three subtypes), sensilla basiconica (with three subtypes), sensilla trichodea, sensilla placodea and sensilla coeloconica. It is worth noting that sensilla chaetica III distributed only on the fixed position of male antennae. In addition, the functional morphology of antennae of H. variegata were compared with other lady beetles from multiple perspectives. Specially, the function of sensilla were also discussed according to their morphology, location and information from previous studies.
Management and Risk in the Frame of Ipm with Biological Control Methods

The demographic development of human population, the pollution, with pesticides, the needs for better quality crops, determined the farmers, policy makers, scientists and the public to make steps further in order to adopt strategies, to issue laws, guides, directives to implement in practice the use of IPM and biological control of pests and Phyto-pathogens for implementing sano-genetic advanced agriculture. This is a short review paper discussing the modern and future IPM.
Policy Risk and the Business Cycle ∗

The argument that uncertainty about monetary and ﬁscal policy has been holding back the recovery in the U.S. during the Great Recession has a large popular appeal. This paper uses an estimated New Keynesian model to analyze the role of policy risk in explaining business cycles. We directly measure risk from aggregate data and ﬁnd a moderate amount of time-varying policy risk. The “pure uncertainty”-eﬀect of this policy risk is unlikely to play a major role in business cycle ﬂuctuations. In the estimated model, output eﬀects are relatively small because policy risk shocks are i) too small and ii) not suﬃciently ampliﬁed.
Subjective experience of social cognition in young people at Ultra-High Risk of psychosis: a 2-year longitudinal study

Abstract Purpose Impairments in SC have been reported in people at Ultra-High Risk (UHR) of psychosis exclusively using neurocognitive tasks. The aims of this study are (1) to assess subjective experience of SC in adolescent and young adult community help-seekers identified through UHR criteria, (2) to explore significant associations of SC with psychopathology and functioning in UHR individuals; and (3) to monitor longitudinally the SC stability after a 2-year follow-up period. Methods: Participants (97 UHR, 141 First-Episode Psychosis [FEP], and 98 non-UHR/FEP), aged 13-35 years, completed the Comprehensive Assessment of At-Risk Mental States (CAARMS) and the GEOPTE scale of social cognition for psychosis. Within the UHR group, a multiple linear regression analysis (with GEOPTE scores as independent variables and CAARMS dimension subscores and treatment measures as dependent variables) was also performed across the 2-year longitudinal design. Results: In comparison with non-UHR/FEP, both UHR and FEP subjects showed significantly higher GEOPTE scores. Both after 12 and 24 months of follow-up, UHR individuals had a significant decrease in severity on GEOPTE SC subscore. In the UHR group, GEOPTE scores showed significant positive correlations with general psychopathology, positive and negative symptoms. Regression analysis showed a significant contribution of SC in predicting baseline social isolation, impaired role functioning, and general psychopathology. After 1 year of follow-up, improvement in SC was predicted by the number of psychotherapy sessions and lower doses of antipsychotics. Conclusions: SC deficits are prominent in UHR individuals and are similar in severity to those of FEP patients. However, they tend to decrease over time along with the delivery of targeted, specialized interventions for early psychosis.
Wing-body aeroelasticity on parallel computers

This article presents a procedure for computing the aeroelasticity of wing-body configurations on multiple-instruction, multiple-data parallel computers. In this procedure, fluids are modeled using Euler equations discretized by a finite difference method, and structures are modeled using finite element equa- tions. The procedure is designed in such a way that each discipline can be developed and maintained independently by using a domain decomposition approach. A parallel integration scheme is used to com- pute aeroelastic responses by solving the coupled fluid and structural equations concurrently while keep- ing modularity of each discipline. The present procedure is validated by computing the aeroelastic re- sponse of a wing and comparing with experiment. Aeroelastic computations are illustrated for a high speed civil transport type wing-body configuration. HE analysis of aeroelasticit y involves solving fluid and structural equations together. Both uncoupled and coupled methods can be used to solve problems in aeroelasticit y associated with nonlinear systems.1 Uncoupled methods are less expensive but are limited to very small perturbations with moderate nonlinearity. However, aeroelastic problems of aero- space vehicles are often dominated by large structural defor- mations and high flow nonlinearities. Fully coupled pro- cedures are required to solve such aeroelasticity problems accurately. Such coupling procedures result in an increased level of complication. Therefore, aeroelastic analysis has been mostly performed by coupling advanced computational fluid dynamics (CFD) methods with simple structural modal equations or ad- vanced computational structural dynamics (CSD) methods with simple flow solutions. However, these approaches can be less accurate for the aeroelastic analysis of practical problems such as a full aircraft configuration in transonic regime. It is necessary to develop a fully coupled procedure utilizing ad- vanced computational methods for both disciplines. Recently, coupled fluid-structural interaction problems are being studied using finite difference Euler or Navier-Stokes flow equations and finite element structural equations of mo- tion as demonstrated by an aeroelastic code ENSAERO.2'3 However, applications are limited to simple structural models. For the complicated fluid and structural models, computations are performed in a step-by-step fashion.4 The main reason is that the use of detailed models for both disciplines requires unprecedented computing speeds and amounts of memory. The emergence of a new generation of parallel computers can pos- sibly alleviate the restriction on the computational power. To solve the coupled fluid-structural equations some at- tempts have been made to solve both fluids and structures in
Outbreak of leaf spot and fruit rot in Florida strawberry caused by Neopestalotiopsis spp.

Pestalotiopsis-like species have been reported affecting strawberry worldwide. Recently, severe and unprecedented outbreaks have been reported in Florida commercial fields where leaf, fruit, petiole, crown, and root symptoms were observed, and yield was severely affected. The taxonomic status of the fungus is confusing since it has gone through multiple reclassifications over the years. Morphological characteristics, phylogenetic analyses, and pathogenicity tests were evaluated for strawberry isolates recovered from diseased plants in Florida. Phylogenetic analyses derived from the combined ITS, β-tub, and tef1 regions demonstrated that although there was low genetic diversity among the strawberry isolates, there was a clear separation of the isolates in two groups. The first group included isolates recovered over a period of several years, which was identified as Neopestalotiopsis rosae. Most isolates recovered during the recent outbreaks were genetically different and may belong to a new species. On PDA, both groups produced white, circular, and cottony colonies. From the bottom, colonies were white to pale yellow for Neopestalotiopsis sp. and pale luteous to orange for N. rosae. Spores for both groups were five-celled with three median versicolored cells. Mycelial growth and spore production were higher for the new Neopestalotiopsis sp. isolates. Isolates from both groups were pathogenic to strawberry roots and crowns. However, the new Neopestalotiopsis sp. proved more aggressive in fruit and leaf inoculation tests, confirming observations from the recent outbreaks in commercial strawberry fields in Florida.
Prevalence of Lifetime History of Traumatic Brain Injury among Older Male Veterans Compared to Civilians: A Nationally Representative Study.

Traumatic brain injury (TBI) is common among older adults as well as among Veterans in the United States and can increase risk for dementia. We compared prevalence of TBI in older male Veterans and civilians using a nationally representative sample. We examined data from 599 male respondents to the 2014 Wave of the Health and Retirement Study (HRS), a nationally representative survey of older adults, randomly selected to participate in a comprehensive TBI survey. Respondents self-reported no injury, non-TBI head/neck injury (NTI), or TBI. We used weighted analyses to examine prevalence of injury and relative risk of injury sub-types. Among male Veterans, we found a national prevalence of over 70% for lifetime history of any head/neck injury (TBI plus NTI), 14.3% for multiple NTI, and 36% for lifetime history of at least one TBI. In contrast, prevalence estimates for male civilians were 58% for lifetime history of head/neck injury, 4.8% for multiple NTI, and 45% for lifetime history of at least one TBI (all comparisons p<0.001). Male civilians have higher self-reported TBI prevalence, while male Veterans have higher self-reported NTI and multiple-NTI prevalence. Further research on drivers of the unexpectedly higher prevalence of lifetime history of TBI in male civilians, as well as on mechanisms and sequelae of the highly prevalent non-TBI head/neck injuries among older male Veterans, is warranted.
Influence of substrates and buffer layers on the quality of NbN ultra thin film for THz HEB

In order to improve the crystalline quality of NbN ultra thin film for THz HEB applications, several buffer layers have been selected and investigated. The influence of the buffer layers on thermal boundary resistance of membrane-type Hot Electron Bolometer (HEB) devices and on their IF bandwidth is discussed. The influence of substrates and buffer layers on the quality of NbN ultra thin film has been studied by performing Atomic Force Microscopy (AFM) and low reflectometry measurements on NbN films on different substrates (3 μm SOI substrate and MgO buffered 3 μm SOI substrate). In particular, the physical properties (roughness and thickness) of NbN film layers have been carefully measured.
Tracking and Classification of Dynamic Obstacles Using Laser Range Finder and Vision

A multi-module architecture to detect, track and classify objects in semi-structured outdoor scenarios for intelligent vehicles is proposed in this paper. In order to fulfill this task it was used the information provided by a laser range finder (LRF) and a monocular camera. The detection and tracking phases are performed in the LRF space, and the object classification methods work both in laser (with a Majority Voting scheme and a Gaussian Mixture Model (GMM) classifier) and in vision spaces (AdaBoost classifier). A sum decision rule based on the Bayesapproach is used in order to combine the results of each classification technique, and hence a more reliable object classification is achieved. Experiments using real data confirm the robustness of the proposed architecture.
Preoperative period of potentially contaminated surgeries: risk factors for surgical site infection

Objective: To associate risk factors of the preoperative period of potentially contaminated surgeries performed in a teaching hospital in the southern region of Brazil with the occurrence of surgical site infection in the postoperative period in the hospital and at home. Methods: A quantitative descriptive cross-sectional study conducted from February to June 2015 with 90 participants by means of individual data collection and observation, from the preoperative period, immediate postoperative period and up to seven days after discharge. The Statistical Package for Social Sciences was used for data analysis. Categorical variables were analyzed descriptively by simple frequency and percentages, and numerical variables by position and dispersion measurements. Results: The surgical site infection in the postoperative period in the hospital occurred in 10% of participants, and in the postoperative period at home in 46.7%. Risk factors: gender, age, underlying diseases, medications, alcoholism and smoking habits were significant for the development of these infections. Conclusion: Checking the health history and performing follow-up of surgical patients during the preoperative period and surgical recovery to reduce surgical site infection are recommended.
