SITE QUALITY CURVES FOR AFRICAN MAHOGANY PLANTATIONS IN BRAZIL
Authors: Ribeiro Andressa , Ferraz Filho Antonio Carlos , Tomé Margarida , Scolforo José Roberto Soares
Published: March 2017

ABSTRACT Site quality estimation is an important tool in forest management since it is useful for modeling growth and yield for even-aged stands. Data from African mahogany (Khaya ivorensis A. Chev.) Brazilian plantations were used to develop a model to predict dominant height growth, comparing dynamic base-age invariant site index models with the guide curve method (static models). For the evaluation of the candidate models qualitative and quantitative criteria were used. We also verified the stability of the candidate models, preferring a model providing fewer site class changes when predicting site index from different ages. The Lundqvist-Korf function fitted with the guide curve method proved to be effective and accurate for site classification and dominant height predictions of African mahogany stands. The range of observed site index, at a reference age of 15, was between 17 and 33 meters.

ABSTRACT Knowing how a wildfire will behave is extremely important in order to assist in fire suppression and prevention operations. Since the 1940’s mathematical models to estimate how the fire will behave have been developed worldwide, however, none of them, until now, had their efficiency tested in Brazilian commercial eucalypt plantations nor in other vegetation types in the country. This study aims to verify the accuracy of the Rothermel (1972) fire spread model, the Byram (1959) flame length model, and the fire spread and length equations derived from the McArthur (1962) control burn meters. To meet these objectives, 105 experimental laboratory fires were done and their results compared with the predicted values from the models tested. The Rothermel and Byram models predicted better than McArthur’s, nevertheless, all of them underestimated the fire behavior aspects evaluated and were statistically different from the experimental data.

RESUMO A modelagem do comportamento do fogo consiste em uma importante tarefa que pode ser utilizada para atividades de prevenção e combate. Entretanto, com base em estudos anteriores, os modelos comumente utilizados em outros países não o estimam corretamente nos plantios de eucalipto híbrido no Brasil. Sendo assim, este estudo teve por objetivo construir novos modelos empíricos para estimar a velocidade de propagação, comprimento das chamas e consumo do material combustível para o fogo dentro da respectiva vegetação em questão. Para tal, 105 queimas laboratoriais foram realizadas em que as principais características meteorológicas e do material combustível que poderiam interferir no comportamento do fogo foram controladas e/ou medidas. Variáveis dependentes e independentes foram correlacionadas por meio da regressão multivariada. O modelo para a velocidade de propagação proposto baseou-se na velocidade do vento, densidade do leito e no teor de umidade do material combustível de 1h de timelag (r2 = 0,86); o modelo para o comprimento das chamas baseou-se na espessura do leito, no teor de umidade do material combustível de 1h de timelag e na velocidade do vento (r2 = 0,72); o modelo para o consumo do material combustível teve como variáveis independentes o teor de umidade do material combustível de 1h de timelag, a densidade do leito e a carga do material combustível de 1h de timelag (r2 = 0,80). Os modelos construídos serviram de base para o desenvolvimento do software “Eucalyptus Fire Safety System”.

Abstract The occurrence of viable cells in mammary gland secretions attests the functionality of the defense system. This fact, along with applied medicine, is fundamental for the healing udder. The objective of this study was to evaluate the in vitro viability of milk leukocytes challenged with four intramammary anti-mastitis drugs. We collected eight cow milk samples that were negative after a bacteriological examination. Cell suspensions were submitted to an evaluation of viability through Trypan Blue exclusion before and after incubation with the drugs. Mean pre-incubation viability rate (± standard deviation) of milk cells was 50.17% (± 6.50). Mean post-incubation viability rates (± standard deviation) of control group (devoid of any drug), Drug 1 (anhydrous cephalonium), Drug 2 (gentamicin), Drug 3 (procaine benzylpenicillin associated with dihydrostreptomycin nafcillin), and Drug 4 (benzathine cloxacillin) were, respectively, 31.36% (± 3.61); 26.23% (± 4.49); 7.82% (± 2.33); 3.10% (± 0.94); and 30.33% (± 4.14). The uppermost impairments were found when milk cells were challenged with Drug 2 and Drug 3. Although antimicrobial activity of tested drugs was not appraised, and a single aspect of cell function was tested, we concluded that treatments 2 and 3 could impair the functionality of milk leukocytes and could provide an ineffective immunological response, and an effective response is essential to control mammary infections.

Published: March 2017

Abstract The Cerrado Biome is considered one of the world's biodiversity hotspots because of its rich biodiversity, the high level of endemism and the increasing threat. The Cerrado is composed by a mosaic of different vegetation types, including physiognomies that vary from grasslands (campo limpo) to savannas (typical cerrado or cerrado sensu stricto) and cerrado woodlands (cerradão). However, the factors that determine the composition of the Cerrado’s flora and the structure of the physiognomies that compose this biome are still poorly understood. Here, we investigate the influence of the chemical and granulometric properties of the soil and the effect of geographic distance on the occurrence and abundance of woody species in three Cerrado phytophysiognomies – cerrado woodland (cerradão), dense cerrado savanna and typical cerrado savanna – in the Cerrado-Amazon transition. We tested the hypothesis that the edaphic characteristics and geographic space determine the species composition and the structure of the woody vegetation of these three phytophysiognomies. We demonstrate that the dissimilarities in the structure and composition of the three sites were determined more by space (13% of explanation) than edaphic properties (1%), but primarily by the interaction between these two factors (26%). We conclude that, in situations where the chemical and granulometric properties of the soil are relatively homogeneous, as we found in the present study, geographic distance between sites has a greater influence than variation in the substrate’s properties on modelling the occurrence and abundance of the woody plant species in the Cerrado.

Published: March 2017

Abstract Cladocerans occupy an important position among the bacterial consumers in freshwater food webs, being relatively non-selective filter feeders that can exert a strong impact on microbial populations. We evaluated the bacterivory potential of three cladocerans species of subtropical and tropical occurrence (Ceriodaphnia silvestrii, Daphnia gessneri and Ceriodaphnia cornuta) at different life stages, by scanning electron microscopy (SEM) and by the quantification of their bacterial consumption rates using fluorescently labeled bacteria (FLB). All species showed filter mesh sizes sufficiently narrow to retain bacteria. The largest distance between setules was found in primiparous C. cornuta, and the smallest in neonate D. gessneri. The lowest ingestion (IR) and removal (RR) rates were observed in primiparous C. silvestrii and the highest values were observed in adults of D. gessneri. We conclude that bacteria may be considered an important food supplement, particularly for neonates who presented smaller intersetular distances and higher filtration rates than the other life stages.

Published: March 2017

Abstract Introduction The detection of small caries lesions is still a challenge for dental professionals who in their clinical practice have a wide variety of methods to detect caries on occlusal surfaces. Objective To clinically assess the effectiveness of the Vista Proof fluorescence camera, the Vista Cam digital intraoral micro camera and the International Caries Detection and Assessment System (ICDAS) visual criterion for detecting caries lesions on occlusal surfaces of permanent teeth. Material and method One hundred and seven posterior teeth from adult patients were examined visually and by means of digital radiographs by an examiner who rated them according to the presence or absence of occlusal caries. The teeth were then assessed by the other examiner using ICDAS, fluorescence and magnified digital images. The effectiveness of the methods was measured based on sensitivity, specificity, positive and negative likelihood ratio. For each method, the Receiver Operating Characteristic (ROC) curve and the Area Under the ROC curve (AUROC) were estimated. Result There was exceptional discrimination capacity for the intraoral images (AUROC=.93) and the ICDAS (AUROC=.91), with no significant statistical difference between them (z=.35, p=.73). The fluorescence exhibited an acceptable discrimination capacity (AUROC=0.78), although it was lower than the others. The positive likelihood ratio for the fluorescence was only 2.32, compared to 20.58 for the intraoral image and 58.11 for the ICDAS. Conclusion Both methods and the ICDAS exhibited an adequate clinical performance, although the ICDAS and intraoral image were more effective than the fluorescence.

Published: March 2017

Abstract Introduction: Stroke has a high prevalence in the world’s population and a significant impact on those affected. Objective: To determine the relationship between body functions evaluated according to the International Classification of Functioning, Disability and Health (ICF) parameters and the referral of post-stroke subjects to rehabilitation services in the city of João Pessoa-PB. Methods: This study was an observational cross-sectional study involving patients diagnosed with stroke who were affected for less than 60 months and linked to the Family Health Strategy (Estratégia de Saúde da Família - ESF). The ICF stroke core sets that identify disabilities in the body function dimension were used to construct the research instrument. Access to rehabilitation was explored using a questionnaire developed from a literature review. The statistical method of logistic regression was used to identify the disabilities in body functions that were relevant to the referral of the post-stroke subject for rehabilitation. Results: The functions that were significant (p < 0.05) were functions relating to muscle tone (OR = 2.38), functions relating to voluntary movement control (OR = 2.60), emotional functions (OR = 2.22), and sexual functions (OR = 3.92). Conclusion: The findings of this study indicate that the presence of disability in these functions is associated with the referral of chronic phase post-stroke subjects to rehabilitation. Therefore, rehabilitation services should be organized to meet the specific requirements of treatment of the sequelae caused by stroke.

Published: March 2017

Abstract Introduction Assessing the functional capacity of the upper limbs (UL) is essential to direct treatments in clinical practice but there is a lack of research on specific methods for this end. Objective To verify the relationship of physical activity, grip strength (GS) and body mass index (BMI) with performance on 6-minute Pegboard and Ring Test (6PBRT) in healthy subjects. Methods Cross-sectional, exploratory and quantitative study. Apparently healthy adults were evaluated, both sexes, according to sociodemographic and anthropometric aspects, health conditions, physical activity level (IPAQ - short version), GS and functional capacity of the upper limbs (6PBRT). The data were analyzed descriptively using means, standard deviations, absolute figures and percentages. Correlations were found between variables using Spearman’s correlation coefficient (p < 0.05). The Statistical Package for Social Sciences (SPSS) for Windows, version 17.0 was used for analysis purposes. Results In total, 50 individuals were evaluated, the majority classified as active (54%). The mean GS was 30.70 ± 9,47kgf and the average number of loops moved during the 6PBRT was 277.6 ± 34.48. There was no correlation between the number of rings moved in 6PBRT and the level of physical activity (r = 0.076; p = 0.602), GS (r = -0.008; p = 0.956) or BMI (r = 0.031; p = 0.829). Conclusion The level of physical activity, GS and BMI did not influence the performance on 6PBRT, demonstrated by the lack of correlation between these variables.

Authors: Faria Luiza Martins , Barbosa Sayonara de Fátima Faria
Published: March 2017

Abstract Introduction: Physical function impairment is a significant concern for patients who survive their intensive care unit (ICU) stay, due to its impact on the patient’s independence and functional status. In this context, the choice of a suitable instrument for the assessing functional status is important, because an inappropriate assessment could lead to incorrect conclusions regarding patient prognosis, treatment benefits, and condition. Objective: To identify which functional assessment tools are used in Brazil to assess patients who are in ICU. Additionally, we investigated the translation, adaptation, and validation of these instruments for use in this population. Methods: We searched Pubmed, SCIELO, Lilacs, and Scopus in November 2015. No language or date restrictions were applied to the search. Results: Ten studies and seven instruments were identified. The most commonly used instruments were the Karnofsky Performance Status Scale Scores and the Functional Independence Measure. Conclusion: The instruments found in the review were neither specifically developed to assess the functional status of ICU patients, nor were they validated for use in this population in Brazil. Transcultural development or adaptation studies should be conducted, followed by a validation process.

Abstract Sarcocystis spp., Neospora spp., and Toxoplasma gondii are Apicomplexa protozoa that can infect horses. This study aimed to investigate the occurrence of antibodies against Sarcocystis spp., Neospora spp., and T. gondii in horses slaughtered in southern Brazil. The presence of histological lesions, tissue cysts, and Sarcocystis spp. DNA in the hearts of these horses was also investigated. A total of 197 paired serum and heart samples were evaluated by serology and direct microscopic examination; 50 of these samples were subjected to histopathological and PCR analyses. Antibodies against at least one of the protozoa were detected in 146 (74.1%) of the serum samples. The frequencies of positive serology were: 36% (71/197) against Sarcocystis spp., 39.1% (77/197) against Neospora spp., and 47.2% (93/197) against T. gondii. No cysts, Sarcocystis spp. DNA, or histopathological lesions were observed in myocardial tissue samples. The frequencies of antibody seropositivity against Sarcocystis spp., Neospora spp., and T. gondii showed that horses are frequently infected by these parasites in southern Brazil. The absence of sarcocysts in horse tissues is compatible with their role as aberrant/accidental hosts in the life cycle of Sarcocystis spp..

Abstract This study evaluated the influence of the initial weight, feeding period and temperature on weight gain and biological parameters of the non-parasitic phase of partially engorged Rhipicephalus sanguineus females that were artificially fed using plastic tips as feeding devices. The device did not alter the oviposition of the females or any other parameters evaluated. Furthermore, it was observed that the temperature of the feeding the group did not affect the weight gain and biology of ticks. This device has great potential for the development of studies on bioagent transmission because it provides higher intake of blood by ixodid ticks.
New morphological data and molecular diagnostic of Henneguya friderici (Myxozoa: Myxobolidae), a parasite of Leporinus friderici (Osteichthyes: Anostomidae) from southeastern Brazil
Authors: Vidal Letícia Poblete , Luque José Luis
Published: March 2017

Abstract The myxozoan Henneguya friderici is a parasite of the gills, intestine, kidney and liver of Leporinus friderici, a characiform fish belonging to the family Anostomidae. Forty-two specimens of L. friderici that had been caught in the Mogi Guaçú River, state of São Paulo, were studied. Elongated white plasmodia were found in the gill filaments of 10 host specimens (24%). The mature spores had an ellipsoidal body with polar capsules of equal size and caudal length greater than body length. This study also described 18S rDNA sequencing of H. friderici infecting the gill filaments. This produced a sequence of 1050 bp that demonstrated significant genetic differences with previously described species of Henneguya. Similarity analysis using sequences from species that clustered closest to those produced by this study showed that the species with greatest genetic similarity to H. friderici was H. leporinicola, with 94% similarity.

Published: March 2017

The development of permanent energy-efficient houses for ever-increasing urban slum dwellers using sustainable construction materials is a major challenge in developing countries such as India. The exposed building surfaces (walls and roof) play a significant role in controlling the peak cooling load demand in climatic zones where median temperatures are high. This study examines the baseline building model performance for peak cooling load demand using the traditional construction materials for walls (fly ash bricks) and roof (reinforced cement concrete (RCC)). As approved by standards and local government practice, the building plan for one-, two- and three-storied structures was modelled in Revit software. With the aim to achieve energy efficiency in a cost-effective manner over the base case model, bio-fuel ash cellular lightweight (BFA-CLW) bricks and expanded polystyrene geofoam (EPGF) as an insulator were analysed. Results indicate that the model with BFA-CLW bricks and an EPGF-RCC roof is energy efficient, cost competitive and would conserve peak cooling load as compared with the base case building model. It can be concluded that to enhance the energy efficiency of urban slum houses, the application of locally available novel sustainable products and a computational approach for faster design decisions should be practised.
The ESRD Quality Incentive Program—Can We Bridge the Chasm?
Authors: Weiner Daniel , Watnick Suzanne
Published: March 2017

The ESRD Quality Incentive Program (QIP) is the first mandatory federal pay for performance program launched on January 1, 2012. The QIP is tied to the ESRD prospective payment system and mandated by the Medicare Improvements for Patients and Providers Act of 2008, which directed the Centers for Medicare and Medicaid Services to expand the payment bundle for renal dialysis services and legislated that payment be tied to quality measures. The QIP links 2% of the payment that a dialysis facility receives for Medicare patients on dialysis to the facility’s performance on quality of care measures. Quality measures are evaluated annually for inclusion on the basis of importance, validity, and performance gap. Other quality assessment programs overlap with the QIP; all have substantial effects on provision of care as clinicians, patients, regulators, and dialysis organizations scramble to keep up with the frequent release of wide-ranging regulations. In this review, we provide an overview of quality assessment and quality measures, focusing on the ESRD QIP, its effect on care, and its potential future directions. We conclude that a patient-centered, individualized, and parsimonious approach to quality assessment needs to be maintained to allow the nephrology community to further bridge the quality chasm in dialysis care.
Assessing hillslope-channel connectivity in an agricultural catchment using rare-earth oxide tracers and random forests models

Published: March 2017

Soil erosion from agricultural areas is a large problem, because of off-site effects like the rapid filling of reservoirs. To mitigate the problem of sediments from agricultural areas reaching the channel, reservoirs and other surface waters, it is important to understand hillslope-channel connectivity and catchment connectivity. To determine the functioning of hillslope-channel connectivity and the continuation of transport of these sediments in the channel, it is necessary to obtain data on sediment transport from the hillslopes to the channels. Simultaneously, the factors that influence sediment export out of the catchment need to be studied. For measuring hillslope-channel sediment connectivity, Rare-Earth Oxide (REO) tracers were applied to a hillslope in an agricultural catchment in Navarre, Spain, preceding the winter of 2014-2015. The results showed that during the winter no sediment transport from the hillslope to the channel was detected.To test the implication of the REO results at the catchment scale, two contrasting conceptual models for sediment connectivity were assessed using a Random Forest (RF) machine learning method. The RF method was applied using a 15-year period of measured sediment output at the catchment scale. One model proposes that small events provide sediment for large events, while the other proposes that only large events cause sediment detachment and small events subsequently remove these sediments from near and in the channel. For sediment yield prediction of small events, variables related to large preceding events were the most important. The model for large events underperformed and, therefore, we could not draw any immediate conclusions whether small events influence the amount of sediment exported during large events. Both REO tracers and RF method showed that low intensity events do not contribute any sediments from the hillslopes to the channel in the Latxaga catchment. Sediment dynamics are dominated by sediment mobilisation during large (high intensity) events. Sediments are for a large part exported during those events, but the system shows a memory of the occurrence of these large events, suggesting that large amounts of sediments are deposited in and near the channel after these events. These sediments are gradually removed by small events. To better understand the delivery of sediments to the channel and how large and small events influence each other more field data on hillslope-channel connectivity and within-channel sediment dynamics is necessary.

Малый бизнес в современной России: проблема источников финансирования
Authors: Шавалеева Лена Салаватовна
Published: March 2017

Малый бизнес – один из важных резервов экономического развития современной России. Однако его развитие, наряду с другими причинами, серьезно тормозится нехваткой источников финансирования. Использование собственного капитала, бюджетных средств, заемного капитала и инвестиций сильно ограничивается негативным влиянием целого ряда финансово-экономических, организационно-правовых, кадрово-управленческих и иных факторов. В последние годы ужесточение требований банков к заемщикам все чаще побуждает малый бизнес налаживать деловые контакты с венчурными фондами. Однако далеко не все предприниматели готовы работать в достаточно специфических условиях, диктуемых этим сегментом бизнеса. Большую роль в решении актуальных инвестиционных проблем российского малого бизнеса призвано играть государство, политика которого в данной сфере должна учитывать интересы обеих сторон – и субъектов, и объектов инвестиционных отношений.

Published: March 2017

Debater o papel da cultura digital na universidade na perspectiva de docentes ali envolvidos e analisar criticamente os principais usos atribuídos em sala de aula a esses aspectos compuseram a intenção central dessa investigação. A metodologia, de abordagem qualitativa, teve como instrumento de coleta de dados um questionário aberto que foi aplicado a 31 docentes da área de ciências humanas, biológicas, exatas e tecnológicas em um centro universitário na cidade de São Paulo.Os resultados indicam que os professores posicionam-se em relação à cultura digital expressando a possibilidade de construir aulas mais interativas e criativas, contribuindo efetivamente com o aprendizado na universidade. Declaram acionar diferentes recursos digitais em aula, de forma online e offline, de maneira colaborativa ou não com predomínio de slides em aparelhos multimídia, filmes e atividades na plataforma Moodle. Nas sugestões priorizam o cuidado com a infraestrutura tecnológica institucional e em menor grau a formação docente, que foi apresentada por eles como um dos desafios centrais. Faz-se urgente repensar a  cultura digital a partir de um referencial crítico-reflexivo de formação e conhecimento de novas interfaces digitais e de uma equilibrada gestão dos recursos tecnológicos de cada instituição de ensino.

A Study of Interest and Perception of the Financial Planning Profession Among Finance Undergraduate Students
Authors: Chen Leon , Severns Roger
Published: March 2017

We conducted an annual survey of undergraduate students taking finance courses over the past 5 years (2009–2014). Our results showed that although more than 70% of students considered the financial planning profession to some extent, the percentage of students who had seriously considered it declined over time, despite the increasing number of new hires in the area. Our regression models showed that students with a higher level of related experience were more likely to show increased interest over time and that male students were less likely to change their minds regarding their decisions to become a financial planner. These results suggest that academic programs need to form stronger partnerships with the industry and to facilitate better communications with female students regarding the profession.
Low- and Moderate-Income Tax Filers Underestimate Tax Refunds: Implications for Financial Counseling and Policy
Authors: Hall Crystal C. , Romich Jennifer L.
Published: March 2017

Low- and moderate-income tax filers often receive refund and tax credit checks that easily total a fifth or more of their total annual income. This study uses data collected in 2009 and 2010 from 79 clients of a volunteer income tax assistance (VITA) program to compare filers’ estimates of their returns before the tax preparation process with their returns calculated by trained VITA volunteers. Most filers (75%) underestimated their refunds, and 52% underestimated by $500 or more. Hence, at least some portion of the refund arrives as an unanticipated windfall. Counseling and planning work with low- and moderate-income families should take these significant lump sum income events into consideration.
Financial Management and Culture: The American Indian Case
Authors: Danes Sharon M. , Garbow Jennifer , Jokela Becky Hagen
Published: March 2017

Study investigates distal and proximal contextual influences of the American Indian culture that affect financial decisions and behaviors. Primary household financial managers were interviewed. Study was grounded in Deacon and Firebaugh’s Family Resource Management theory. Findings indicated that American Indians view many concepts differently than conventional disciplinary meanings. Most critical is that money is not the only currency used within the culture but relationships and nature are also used as other currencies. Further findings of note are (a) the cultural belief that resources must be shared with all family members is seen as an obligation and often creates major resource demands, (b) spirituality and nature are of major importance in resource decisions, and (c) the holistic, integrated view of health and well-being is essential to consider when working with American Indians on resource management. Three resource management patterns were discovered: mainstream, traditional, and hybrid. Expense and income worksheets were developed reflecting cultural nuances.
Use of Financial Planners and Portfolio Performance
Authors: Lei Shan , Yao Rui
Published: March 2017

Using data from the 2013 Survey of Consumer Finances, this study evaluates the potential effect of using financial planners on household portfolio performance, which was measured by Sharpe Ratio. Results revealed that households that reported using financial planners demonstrated better portfolio performance than those that did not. This lends empirical support to claims that professional financial planning services provide value to clients. Implications for investors, financial planning professionals, and researchers are discussed. Considering the direct relation between wealth accumulation and portfolio performance, financial planners should explore ways in which to work with those with limited resources to help them realize the benefits of using financial planners and improve their portfolio performance as a result.
Care-Related Out-of-Pocket Expenditures in Canada

Published: March 2017

This research examined the prevalence and amount of care-related out-of-pocket expenditures of family caregivers and the factors that influence this spending. Secondary analysis of 2007 General Social Survey (Cycle 21) data yielded population estimates for Canadians age 45 years and older. Thirty-five percent of respondents—1.2 million Canadians—reported care-related out-of-pocket expenditures, which amounted to almost $12.6 million. Caregivers who were more likely to incur these costs reported higher levels of stress, were caring for a family member or friend with more complex health conditions, were providing more intense levels of care, and lived further away from the care receiver. We find that care-related out-of-pocket spending is common among Canadian caregivers, that it can be substantial, and that relatively few caregivers receive financial supports that can defray these costs.

Background: Why HIV-infected individuals have poor responses to standard dose and schedule hepatitis B virus immunization is not well understood.Methods: We compared the serologic and cellular immune profiles of treated HIV-infected individuals with similar durations of infection and preserved CD4 counts (>350 cells/microliter) by hepatitis B vaccine (HBV) response before and after vaccination.Results: Similar levels of immune activation and plasma cytokine profile were found between non-responders and responders. The baseline plasma levels of CXCL-13, a surrogate of germinal center reactivity, were significantly lower in HBV responders compared to HBV non-responders and were a predictor of both vaccine response and titer. Furthermore, response to HBV vaccination was associated with a significantly higher frequency of circulating IgGhigh memory B cells post vaccination and preserved Th1 antigen-specific T-cell responses.Conclusions: Taken together, our data suggest that preserved Th1 responses are associated with hepatitis B vaccine response in treated HIV infection.
Linear Mathematical Model for Seam Tracking with an Arc Sensor in P-GMAW process

Published: March 2017

Arc sensors have been used in seam tracking and widely studied since the 80s; commercial arc sensing products for T and V shaped grooves have been developed. However, it is difficult to use these arc sensors in narrow gap welding because arc stability and sensing accuracy are not satisfactory. Pulse gas melting arc welding (P-GMAW) has been successfully applied in narrow gap welding and all position welding processes, so it is worthwhile to research P-GMAW arc sensing technology. In this paper, we derived a linear mathematical P-GMAW model for arc sensing, and the assumptions for the model are verified through experiments and finite element methods. Finally, the linear characteristics of the mathematical model were investigated. In torch height changing experiments, uphill experiments, and groove angle changing experiments the P-GMAW arc signals all satisfied the linear rules. In addition, the faster the welding speed, the higher the arc signal sensitivities; the smaller the groove angle, the greater the arc sensitivities. The arc signal variation rate needs to be modified according to the welding power, groove angles, and swing or rotate speed.
