Genetic Mapping and QTL Analysis for Disease Resistance

24 One mapping population derived from Tifrunner × GT-C20 has shown great potential in 25 developing high dense genetic map and identification of QTLs for important disease 26 resistance, Tomato spotted wilt virus (TSWV) and leaf spot (LS). Both F2 and F5 generation27 based genetic maps were constructed previously with 318 and 239 marker loci, respectively. 28 Higher map density could be achieved with the F2 map (5.3 cM/locus) as compared to the F5 29 (5.7 cM/locus). QTL analysis using multi-environment phenotyping data from F8 and higher 30 generation for disease resistance identified 54 QTLs in the F2 map including two QTLs for 31 thrips (12.14 – 19.43% PVE), 15 for TSWV (4.40–34.92% PVE) and 37 for LS (6.61– 32 27.35% PVE). Twenty-three QTLs could be identified in F5 map including one QTL for 33 thrips (5.86% PVE), nine for TSWV (5.20 – 14.14% PVE) and 13 for LS (5.95–21.45% 34 PVE). Consistent QTLs identified in each map have shown higher phenotypic variance than 35 non-consistent QTLs. As expected, the number of QTLs and their estimates of phenotypic 36 variance were lower in the F5 map. This is the first QTL study reporting novel QTLs for 37 thrips, TSWV and LS in peanut, and thus, future studies will be conducted to refine these 38 QTLs. 39 40 41 42 The Plant Genome: Posted 31 July 2013; doi: 10.3835/plantgenome2013.05. 0018
Feasibility study of a positron lifetime spectrometer for measurements of porous and polymer films with a DC positron beam

Positron Annihilation Lifetime Spectroscopy (PALS)is an increasingly important analysis technique that can be efficiently used to characterize the free volume sizes in porous silica and polymer thin ﬁlms. In this document a design of a non-expensive lifetime spectrometer to measure positron annihilation lifetime spectra in thin ﬁlms with a continuous (DC) magnetically guided slow positron beam is described. The system uses secondary electrons emitted from the surface of the sample by the primary positrons in order to generate a START timing signal. Simulation results show that the time resolution can be expected to be $\lessim$ 300 ps at FWHM.
Numerical Predictions of the Responses of a Square Prism Based on the Approach of Rigid Aeroelastic Model

ABSTRACT: A numerical method is developed to predict the dynamic responses of a square prism based on the concept of a rigid aeroelastic model. Verification of the accuracy of the numerical model is firstly carried out by comparing the numerical results with those from available wind tunnel measurements. The model is then used to predict the responses of a prototype building. Based on the resulting along-wind and across-wind responses as well as the corresponding aerodynamic damping ratios, the mechanisms are investigated in detail.
Preservice teachers' pedagogical content knowledge of using particle models in teaching chemistry

In this article, we describe the results of a study of the pedagogical content knowledge (PCK) of preservice chemistry teachers in the context of a postgraduate teacher education program. A group of preservice teachers (n = 12) took part in an experimental introductory course module about the use of particle models to help secondary school students understand the relationship between phenomena (e.g., properties of substances, physical and chemical processes) and corpuscular entities (e.g., atoms, molecules, ions). The module emphasized learning from teaching by connecting authentic teaching experiences with institutional workshops. Research data were obtained from answers to written assignments, transcripts of workshop discussions, and reflective lesson reports, written by the participants. The outcomes of the study revealed that, initially, all participants were able to describe specific learning difficulties, such as problems secondary school students have in relating the properties of substances to characteristics of the constituent particles. Also, at this stage, all preservice teachers acknowledged the potential importance of using models of molecules and atoms to promote secondary school students' understanding of the relationship between phenomena and corpuscular entities. After teaching, all preservice teachers demonstrated a deeper understanding of their students' problems with the use of particle models. In addition, about half of the participants had become more aware of the possibilities and limitations of using particle models in specific teaching situations. Through learning from teaching, the preservice teachers further developed their PCK of using particle models, although this development varied among preservice teachers studied. © 2005 Wiley Periodicals, Inc.

An unstructered DG-FEM method for nonlinear wave-structure interaction

This abstract describes recent work on applying the Discontinuous Galerkin Finite Element Method (DG-FEM) to solve a set of highly accurate Boussinesq-type equations for the interaction of nonlinear waves with bottom mounted structures. We present here some validation results in 2-D which establish the accuracy and convergence properties of the scheme, along with some preliminary results in 3-D for the diﬀraction of waves around bottom mounted structures. The mathematical model being applied is derived in [7, 6], and we consider both the Pad´e (4,4) and the Pad´e (2,2) versions of this method which can accurately propagate nonlinear waves in relative water depths up to kh ≈ 25 & 10 respectively ( k the wavenumber, h the water depth) up to something near the stable breaking limit. The associated wave kinematics (vertical distribution of pressure and velocity) are accurate up to kh ≈ 12 & 4 respectively. A ﬁnite diﬀerence based solution to these equations has been used to obtain solutions for highly nonlinear wave run-up on piecewise rectangular structures as described in [4, 5] and references therein. This solution, as implemented, is limited to a rectangular, uniformly spaced grid and hence piecewise rectangular structures. The main goal of the present work is to remove this limitation and allow the treatment of more general geometries. The choice of a DG-FEM methodology provides the geometric ﬂexibility of an unstructured grid while also providing ﬂexibility in the local order of accuracy of the numerical scheme. This combination could lead to improved computational eﬃciency, although this has yet to be demonstrated. To brieﬂy the mathematical we consider water waves in 3-D using a coordinate system with origin in the still-water plane and the z -axis
USE OF GIS IN THE ASSESSMENT OF AIR POLLUTION IN CUSCO, PERU by JOHN LANIER PEARCE

Cusco, Peru is a city of 323,644 full time residents and an average annual tourist population of 800,000. Located at 71° 58’28”W and 13°31’23”S and covering 617 km the city resides in a central valley high in the Andes Mountains averaging over 11,000 ft in elevation. Ambient air quality had never been assessed in Cusco. There were three objectives for this research: first, investigate ambient, regional, and street-level air pollutant concentrations in Cusco, second, characterize the spatiotemporal relationships between particle concentrations and human and physical geographical factors, and third, model particulate concentrations in a specific region of Cusco for select time periods during the day. The study took place from July 10 July 21, 2005.

The Development of a Social Service Quality Scale for Disabled Adults

The purpose of this study is to identify the components of social service quality, and to develop a reliable and valid measurement instrument. The concept of a social care service quality for disabled adults is clarified and the processes involved in scale development presented. Three core components of social care service quality are identified, namely, process, outcome, and engagement quality. The reliability and validity of this three-factor scale are verified using empirical data. Disability service institutions were selected using Korea Health & Welfare Information Service’s disability service institution information. Survey subjects 1000 case were selected from institutions and service users in 11 regions. It was found that the social service quality scale has predictive capability in relation to correlation among the three core components (=77.638, RMSEA=.047, GFI=.984, CFI=.987). The quality scale tool described in this article will allow disabled adults to have more involvement choosing the social care services that best fit their needs.
Neural and Behavioral Responses to the Use of Auditory Feedback in Vocal Control

A large body of evidence suggests that the motor system maintains a forward model that predicts the sensory outcome of movements. When sensory feedback does not match the predicted consequences, a compensatory response corrects for the motor error and the forward model is updated to prevent future errors. Like other motor behaviours, vocalization relies on sensory feedback for the maintenance of forward models and to stabilize vocalizations. Experiment 1 used event-related potentials (ERPs) to examine sensory processing of short feedback perturbations during an ongoing utterance. In one session, participants produced a vowel at an FO of their own choosing. In another session, participants matched the FO of a cue voice. An FO perturbation of 0,25, 50,100, or 200 cents was introduced for 100 ms. A mismatch negativity (MMN) was observed. Differences between sessions were only found for 200 cents perturbations. Reduced compensation when speakers experienced the 200 cents perturbations suggests that this larger perturbation was perceived as externally generated. The presence of an MMN, and no earlier (N100) response suggests that the underlying sensory process used to identify and compensate for errors in mid-utterance may differ from feedback monitoring at utterance onset. In Experiment 2, we used a frequency altered feedback (FAF) paradigm to study the role of auditory feedback in the control of vocal pitch (F0). We adapted participants to a one semitone shift and induced a perturbation by briefly removing the altered feedback. This was compared to a control block in which a 1 semitone perturbation was introduced into an unshifted trial, or trials were randomly shifted up 1 semitone, and a perturbation was introduced by removing the feedback alteration. The compensation response to mid-utterance perturbations was identical in all conditions, and was always smaller than the compensation to a shift at utterance onset. These results are explained by a change in the control strategy at utterance onset and mid-
Stability of Hyaluronan-Pectic Gel Particles in the Conditions of the Artificial Gastrointestinal Environment

Spherical hyaluronan-pectic gel particles (HPGPs) from hyaluronic acid (HA) and low-methyl esterified pectins of callus cultures of tansy, duckweed, campion and commercial apple pectin were obtained by the method of ionotropic gelation in the presence of calcium ions. We investigated the morphology, swelling and degradation of the obtained HPGPs in the conditions of a simulated gastrointestinal environment and established that the greatest stability in the artificial environment of the digestive tract is achieved with HPGPs obtained from the pectin of tansy callus cultures. HPGPs can be used as potential carriers for drug delivery systems in parts of the small and large intestine. (International Journal of Biomedicine. 2017;7(4):310-314. )
A New Generic Method for Quantifying the Scale Predictability of the Fractal Atmosphere: Applications to Model Verification

AbstractThe authors revisit the issue regarding the predictability of a flow that possesses many scales of motion raised by Lorenz in 1969 and apply the general systems theory developed by Selvam in 1990 to error diagnostics and the predictability of the fractal atmosphere. They then introduce a new generic method to quantify the scale predictability of the fractal atmosphere following the assumptions of the intrinsic inverse power law and the upscale cascade of error. The eddies (of all scales) are extracted against the instant zonal mean, and the ratio of noise (i.e., the domain-averaged square of error amplitudes) to signal (i.e., the domain-averaged square of total eddy amplitudes), referred to as noise-to-signal ratio (NSR), is defined as a measure of forecast skill. The time limit of predictability for any wavenumber can be determined by the criterion or by the criterion , where is the golden ratio and m is a scale index. The NSR is flow adaptive, bias aware, and stable in variation (in a logarithm .
Agent-Based Modelling applied to 5D model of the HIV infection

This paper proposes a Multi-Agents Model to simulate the phenomenon of the infection by the human immunodeficiency virus (HIV). Since the HIV was isolated in 1983 and found to be the cause of the Acquired Immune Deficiency Syndrome (AIDS) in 1984, lots of studies have been carried out to understand the complex dynamics between the HIV virus and the immune system. The simplest model was the 3D mathematical model. But the complexity of this phenomenon and the diversity of cells and actors which affect its evolution requires the use of new approaches such as multi-agents approach that we have applied in this paper. The results of our simulator on the 5D model are promising because they are consistent with biological knowledge’s. Therefore, the proposed approach is well appropriate to the study of population dynamics in general and could help to understand and predict the dynamics of HIV infection.
Does a Blended Infant Massage-Parenting Enhancement Program Improve Infant Health Outcomes?

Purpose: This study aimed to determine whether a blended Infant Massage-Parenting Enhancement Program (IMPEP) improved infant health outcomes (growth, development, safety in home environment/infant safety, and immunizations) among infants of Substance-Addicted Mothers (SAMs) actively engaged in outpatient rehabilitation. Methods: Designed as a randomized, three-group controlled trial testing two levels of psycho-educational intervention (IMPEP versus Parenting Enhancement Program [PEP]) and a control group (standard of care parenting resources), the study was conducted in two substance abuse centers in southeast Florida on a convenience sample of 138 infants. IMPEP or PEP classes were held weekly on Weeks 2-5, with data collected at Baseline, Week 6, and Week 12 via an Infant Detecto Beam Scale with standardized measuring stick, the Bayley Scales of Infant Development, and two instruments developed for this study--the Home Environment Safety Checklist and the Infant Immunization Status Checklist. Data analyses included descriptive and nonparametric inferential tests, using Kruskall-Wallis, ANOVA, post-hoc Wilcoxon Rank Sum, and Mann-Whitney U tests. Results: Infants of IMPEP SAMs preferentially demonstrate greater growth than infants of PEP SAMs, as reflected in length, weight, and head circumference measures at 6 and 12 weeks postBaseline, while overall growth was observed chronologically in all study groups. There were no clinically meaningful differences among study groups in infant development, home and infant safety, as well as immunization status. Conclusion: The findings suggest that IM blended into a parenting enhancement program has value-added effects in promoting infant growth but not in infant development, home and infant safety, and immunization status.
THE CONSIDERATION AND PURPOSE OF BORROWING: AN EMPIRICAL EVIDENCE FROM INDONESIA LISTED COMPANIES

Debt often graced in most of capital structure of companies, particularly in financial statement and became issues in context of trade off theory and pecking order theory in most studies. Debt usually related with profit matter, because it is always want to be achieved by every companies. It started when companies own equity is insufficient to create investment in company’s assets for making profit, then it make debt is one alternative fund for financing investments aimed at achieving the desired profit. The objective of this study is to give answers as empirical evidence for the questions about why companies need debt and what is the relevance capital structure theory to explain this behavioral tendency in these period of observation. Conducting path analysis with trimming model as method of analysis, the results shows that, degree of operating leverage is negatively significant to debt equity ratio and debt equity ratio is negatively significant to return on equity. The implication of this findings shows the application of pecking order theory, because most of companies depend their funding from internal, which is make them have more stable cash flow and beside that, the consideration of business risk is very important so they keep the capital structure in optimum debt that make them have low probability of bankruptcy.
The influence of public debt on the performance of the economy

Thanks to public debt, nations maintain a stable tax rate and at the same time raise expenses for suppressing budget crises. Public debt is considered risk-free and is issued by the national government. However, extensive public debt raises interest rates, extrudes private investments, worsens fixed balance, widens short-term fluctuation and has a negative impact on economic growth. The performance of the economy can be measured mostly by GDP, which is expressed as the monetary value of all finished products and services produced in a certain time period in one country. The aim of this paper is to explore the relationship, or rather identify the mutual correlation of public debt of one country and its performance (GDP). The research includes countries of the European Union, which have an identifiable timeline of public debt and GDP. The source of this data is the database of the World Bank. The information is from the period of years from 1995 through 2015. The correlation of the whole file of countries and then individual countries is ascertained. On the basis of the results, we can state that in the explored sample of countries, high dependence between public debt and GDP has been proven.
Accuracy of circulation estimation schemes applied to discretised velocity field data

Numerical experiments are conducted on the velocity field of the Oseen vortex to determine the effect of random errors in the velocity field on the circulation estimate. The circulation is estimated by either a velocity integral or a vorticity integral over a particular region of integration. A novel method for the determination of this region is used. The accuracy of circulation estimation schemes is characterised in terms of the velocity sample spacing, the amount of random noise in the velocity field and the vorticity estimation scheme used. It is found that, in general, the velocity integral outperforms the vorticity integral in terms of reducing total error.
An integrated production performance measurement system

Presents an original integrated production performance measurement system (IP2MS) based on a model able to examine simultaneously several production performances of different operation centres of a firm. The need for an integrated examination of the performances is of crucial importance for today’s manufacturers in order to achieve a competitive advantage. Obtains a quantitative and homogeneous appraisal of the production performances; furthermore, identifies activities responsible for the major differences between actual and desired levels of performance. The proposed model has been empirically tested in some significant medium‐large enterprises of Northern Italy.
Fusion-based approach to change detection to reduce the effect of the trade-off parameter in the active contour model

This study proposes an approach to unsupervised change detection in which two different change maps are fused using different trade-off parameters of an active contour model. First, the change vector analysis method is conducted to produce a difference image from multitemporal and multispectral remotely sensed images. Second, two change maps are obtained based on the difference image using an active contour model using two different values of the trade-off parameter. Finally, an advantage fusion strategy is proposed to yield a final change map by fusing the two change maps, thereby reducing false alarms and preserving the accurate outlines of the changed regions. Two experiments are conducted with Landsat-7 Enhanced Thematic Mapper Plus and Landsat-5 Thematic Mapper data sets to evaluate the performance of the proposed method. Results confirm the effectiveness of the proposed approach vis-à-vis some of the state-of-the-art methods. This work contributes to the reduction of the effect of the trade-off parameter on the accuracy of the change map.
Collagen quantification in rabbit dermal wounds treated with heterologous platelet-rich plasma gel

Platelet-rich plasma (PRP) has been extensively studied as a biomaterial for wound treatment, and the heterologous PRP is usefulin the event that obtaining the patient’s own blood is impossible. This study aimed to evaluate and compare wound healing in rabbits and quantify the collagen in experimentally induced wounds in a control group and in a group treated with heterologous PRP gel. We hypothesize that this gelis capable of promoting proper healing with no adverse reactions, increased collagen content. The clinical aspects of coloring, edema, hyperemia, exudation, crust, granulation, pain sensitivity, and retraction index of the wounds were measuredon days 7, 14, and 17 after the injury. Collagen quantification by Picrosirius staining and evaluation under polarized light was performed on the 17th day. Crust was present in both groups at all evaluated time points, with the absence of other clinical signs. The wound contraction rate and collagen quantity did not differ between groups. In conclusion, the suggested hypothesis was partially confirmed; the heterologous PRP gel was unable to increase the amount of collagen and accelerate the wound healing process, however, wound healing was efficient and similar in both groups and there was no local adverse reaction. Thus, despite the scarcity of studies in the literature, the heterologous PRP gel is an effective alternative treatment for wounds in the absence of other sources of PRP.
Maternal and fetal effects after inhalation of the herbicide flumetralin

Farm workers at Brazilian tobacco plantations are frequently exposed to toxic chemicals and eventually became contaminated with these products. Flumetralin is a inhibitor of axillary bud growth on tobacco and the effects of gestational exposure should be investigated since many pesticides cross the placental barrier and cause birth defects. The aim of this study was to investigate maternal and fetal effects caused by inhalation of Flumetralin. Pregnant Swiss mice inhaled Flumetralin for 10 or 20 minutes on the seventh day of pregnancy. On the 18 th day, animals were euthanized and subjected to laparotomy for removal of the uterus and embryos. The uterus was weighed and the embryos were examined. Fetuses of both treatments showed visceral changes in the uterus, kidney and liver. Skeletal abnormalities included hydrocephalus and incomplete skull ossification in both groups. In addition, the treatment of 20 minutes exposure caused anomalies in the occipital bone and the 13 rd rib besides internal bleeding. There was reduction in maternal weight gain and impaired intrauterine development of the fetus. The weight of heart, liver, kidneys and testicles of fetuses were significantly decreased. Inhalation of flumetralin proved to be potentially teratogenic in both treatments, with greater damage in the group treated for 20 minutes.
