Telekardiológia: A telemedicina feladatai és kötelességei
Authors: Borbás János , Forczek Erzsébet , Sepp Róbert , Bari Ferenc
Published: October 2017

Abstract:

Telemedicine is a young science that integrates innovations of information-technology and telecommunications into medical science. A successful telemedicine procedure should guarantee reduced workload of the healthcare system with well secured and cost-effective processes. Our goal was to collect the development phases of telemedicine projects through existing telecardiology solutions. Subsequent to reviewing international publications we analyzed the past and present situation of blood pressure monitoring, remote diagnostics of electrocardiography, implantable cardioverter defibrillator monitoring and pocket ultrasound devices. In case of new solutions (a) several internationally accepted, confidently reproducible “good practices” are needed for creating (b) guidelines and recommendations of international medical associations. They have to ensure (c) cost-effective work, with well-designed sustainability and (d) patient confidentiality. Improving (e) education for professionals and patients is essential. We recommend to telemedicine developers to use our standards in order to introduce their products more effectively into clinical practice. It is encouraging that current possibilities of telecardiology partly or fully meet the aforementioned criteria. Further development of the topic can contribute to financial sustainability of our healthcare and might be able to resolve limitations of human resources. Orv Hetil. 2017; 158(44): 1741–1746.
Measuring and interpreting lexical dispersion in corpus linguistics
Authors: Burch Brent , Egbert Jesse , Biber Douglas
Published: October 2017

The frequency of occurrence and the dispersion of a word are measures of a word’s importance in a collection of texts or a corpus. In particular, lexical dispersion is a statistic in corpus linguistics that measures a word’s homogeneity across the parts of a corpus. There are different ways to measure dispersion and the authors compare three approaches. Both formulaic and interpretative issues pertaining to dispersion are discussed in terms of the frequency of a word in the corpus parts and the variability of a word across the corpus. A simulation study and an application involving words from the British National Corpus indicate that the index constructed from the difference between every possible pair of frequencies of the word in the parts of a corpus is preferred.
Intergrated Water Management in the Wood Manufacturing Industry
Authors: Hogland William , Marques Marcia
Published: October 2017

Industrial wastewater management is still neglected in a dominating part of the companies in Sweden and it is not considered as a threat to health of man and environment. The Environmental Science  &Engineering Research Group (ESERG) at LNU has under financial support of KK-foundation and large/medium-size companies in Southern Sweden been studied. Even though the problem has been studied for half a century there is knowledge missing and the stormwater is still a growing problem. Every time rain falls, it washes off oils, microorganisms, litter, sediments, fertilizers, and foreign chemicals from streets, parking lots, lawns, dumpster pads, metal roofs as well from landfill, industrial and harbour sites. Industrial facilities with large impervious surfaces for different types of handling of materials are generating stormwater effluents of different qualities which vary during different time periods and same stands for process water generated of a variety of volumes and often of high pollutant concentrations. In some catchment areas, industrial and small business activities can release a significant portion of some pollutants that ends up directly into receiving waters but also at the municipal wastewater treatment plant. Small businesses and enterprises do not pay attention to routine operations and neither have they had the economic resources to implement preventive measures, treatment facilities or to employ expertise on their particular environmental issues. The project “Development of an Integrated Approach for Industrial Wastewater and Stormwater Management in the Wood Industry Sector” has generated new knowledge about industrial waste water treatment that will be presented at the Linnaeus Ecotech 10 international conference.
The Influence of Training on Preferences
Authors: Alriksson Stina
Published: October 2017

Any organisation or company that want to bring about a change in the process, procedures or internal organisation encounters the issue of training the staff. Training is commonly used to increase dedication in specific issues for example environmental issues, energy saving or enhancing the overall competence of the staff.

When working with environmental- or energy issues, the attitude of the employees is often considered one of the most important factors for the outcome. In this paper two different studies are compared. In both studies training has been included as a background factor in a conjoint analysis study.

The first study concerns preferences for new materials, in this case advanced high strength steel. The respondents were asked to rank eight alternative steel containers and the results, (preferences) were compared to any previous training the individual respondent had. The same procedure was taken in study number two where employees at a paper & pulp industry was asked to rank eight alternative processes with different environmental impacts.

Also here the respondents were asked to state any previous training and the preferences was compared to previous training.

It has not been possible to show any significant connection between preferences in a specific issue and training in the same area. However, it would be interesting to use the method to measure the effect of training on preferences before and after a specific training session.
Alexandre Herculano e a construção do historiador
Authors: Tasca Michelle Fernanda
Published: October 2017

Este artigo busca apresentar a trajetória do historiador português Alexandre Herculano, sua formação e escolhas profissionais. Para tal objetivo, salientamos os anos iniciais de aprendizado e a importância da experiência do exílio, para então, adentrar ao seu desenvolvimento profissional e à junção dos afazeres de bibliotecário aos de historiador. Pretendemos demonstrar a conciliação entre as duas instâncias, ao mesmo tempo em que discutimos o processo de construção da historiografia oitocentista em que o historiador, para escrever sua síntese histórica, deveria antes de tudo reunir os materiais necessários através de incessantes buscas, catalogações e estudos de documentos que ainda não haviam sido adequadamente manuseados para servir a tais propósitos. Por fim, apresenta a forma como Alexandre Herculano foi lido ao longo dos anos e a mudança no viés crítico dos estudos analíticos
Teachers as curriculum leaders: towards promoting gender equity as a democratic ideal
Authors: Simmonds Shan
Published: October 2017

Curriculum is a site of political, racial, gendered, and theological dispute. Teachers who acknowledge this and see the implications for democratic living embrace their teaching practice as curriculum leaders and participate in complicated conversations. With the focus on gender equity as a democratic ideal, this article explores the lived experiences of some South African female teachers. From the findings, it became evident that some teachers still experience their school contexts as pervaded with patriarchy and sexism, and often fear confronting these traditional discourses. Engaging with subject matter that is likely to cause conflict or confrontation is avoided by some teachers because they do not feel comfortable in such contexts. However, some teachers do emerge as activists for gender justice and create awareness of injustice. These teachers are curriculum leaders who advocate for social change. This article concludes by putting forward some suggestions for how teachers can promote social change through their teaching practices.
A multidisciplinary approach to university engagement: key considerations for dynamic mental health teaching and service provision to a disadvantaged community
Authors: Exner Rosemary , Jansen Jennifer , Stroud Louise , du Preez Mingon
Published: October 2017

Scholarship has an obligation to society in that what is discovered through research and what is taught in the lecture hall should extend beyond the classroom and benefit the community. As a hub of training and knowledge in a local community, the challenge for a university exists in integrating community needs and university resources. Mental health is one discipline where this is particularly relevant and urgent due to the growing need for mental health interventions, particularly in under-serviced communities. A university is well positioned to develop a dynamic multidisciplinary approach to the biopsychosocial teaching of mental health practice and community service provision because it has extensive access to networks of current and future professionals. This reflective article explains the development of such a university-community collaborative initiative attached to the Missionvale Psychology Centre (MPC) at the Nelson Mandela University (NMU) located in Port Elizabeth. It examines the broader teaching and learning opportunities afforded the students as well as the need to deliver a much needed service to the local community. In this article, the initiative is qualitatively analysed through the lens of a combination of observational experience and self-reflection. Insights gained and lessons learnt could benefit other health professionals in comparable positions who are faced with similar challenges in response to student training agendas and the social responsibility of universities in developing countries.
Phantasmagoria: communicating an illusion of entrepreneurship in South African school textbooks
Authors: Maistry Suriamurthee Moonsamy , David Roshnee
Published: October 2017

In this article, we examine discourses of entrepreneurship manifest in selected textbooks used in South African primary schools in the postapartheid era. While an attempt was made to purge school textbooks of discriminatory subject matter, the extent to which new powerful discourses have replaced apartheid ideology remains unknown. There is little dispute that school textbook content communicates subliminal messages about the world. Using critical discourse analysis, we reveal constituted and constitutive ideology at work in the textbooks under study. A dominant discourse that emerged was that individuals in society are responsible for their own economic sustainability despite prevailing and historic conditions of oppression and subjugation, and that entrepreneurship is a readily viable way to achieve economic emancipation because it naturally leads to wealth creation. It communicates as a subtle yet deliberate attempt by the state to displace its responsibility for the economic welfare of the individual citizen. The textbooks uncritically legitimate the values of the neoliberal market system. In this paper, we urge the development of a heightened sensitivity when teacher educators, teachers, and learners engage with such ideological persuasions.
Isolation and quantification of MmuPV1 virions from papillomas v1
Authors: Uberoi Aayushi , Lambert Paul
Published: October 2017

In this section we describe our method of isolation and quantification of MmuPV1 virions from papillomas arising in nude mice that can be serially passaged or used to infect other strains of mice. In our studies we have used both crude virus extracts or purified virus particles. Crude virus extract refers to virus present in supernatants obtained by clarifying papillomatous tissue extracts from nude mice. Our method of generation of crude virus extract has been modified from a previous protocol used to isolate merkel cell polyomavirus from human skin swabs(1). Purified virus particles refer to crude extract clarified over an optiprep gradient. Optiprep gradients have been used to purify papillomavirus generated in vitro (2) and have been described in detail on Dr. Chris Buck’s website: https://home.ccr.cancer.gov/LCO/pseudovirusproduction.htm#_ENREF_7. We measure the amount of encapsidated viral genomic DNA to determine the concentration of "viral genome equivalents" (VGE) in any given stock of virus. For this we use a standard agarose gel electrophoresis followed by SYBR-green staining. The same gel can also be used for southern analysis using MmuPV1-specific probes (3) by nick translation as we have described in detail previously(4). Since virus yields from papillomas of nude mice are very high, we have found agarose gel electrophoresis to be sensitive enough to accurately determine virus concentrations. Other methods of virus quantification have also been described in the literature(5, 6). References: 1. Schowalter RM, Pastrana DV, Pumphrey KA, Moyer AL, Buck CB. 2010.

Authors: Venumbaka Nilaya Reddy , Baskaran Porselvi , Mungara Jayanthi , Chenchugopal Madhan , Elangovan Arun , Vijayakumar Poornima
Published: October 2017

Objective: The present study was undertaken to evaluate and compare the apical extrusion of irrigant and depth of irrigant penetration into the dentinal tubules using the EndoVac irrigating system and the manual irrigation system in primary molar teeth. Study design: Twenty five extracted primary molars satisfying the inclusion and exclusion criteria were divided into two groups of 29 roots in each group with an equal distribution of apical foramen area. The teeth were mounted in pre-weighed glass bottles and the canals were irrigated with both the irrigating systems using 5.25% sodium hypochlorite solution mixed with acid fuchsin which enables the irrigating solution to penetrate efficiently into the dentinal tubules. The amount of irrigant extruded was recorded. The roots were sectioned at 2mm, 4mm and 6mm from the apex and examine the depth of irrigant penetration into the dentinal tubules under a stereomicroscope. Results: Apical extrusion of the irrigant was significantly less with the EndoVac system (1.18±1.04gms) when compared to manual irrigation system (2.3±1.55gms) (P<0.05). EndoVac irrigation system showed greater depth of irrigant penetration into the dentinal tubules (49.90±17.52mm, 32.17±12.20mm and 15.70±8.91mm) compared to the manual irrigation system (30.48±16.27mm, 14.74±9.67mm and 5.59±7.09mm) at 6mm, 4mm and 2mm respectively (P<0.05). Results showed that the depth of irrigant penetration into the dentinal tubules with both the irrigating systems was found to be significantly greater in the six mm sections compared to the four mm and two mm sections (P<0.05). Conclusion: The EndoVac irrigation system showed significantly greater efficacy compared to the manual irrigation system in primary molars with less amount of irrigant extrusion and better depth of irrigant penetration into the dentinal tubules.
Clinical Characteristics of Localized Aggressive Periodontitis in Primary Dentition
Authors: Miller Karina , Treloar Tina , Guelmann Marcio , Rody Wellington J. , Shaddox Luciana M
Published: October 2017

Objectives: Due to the low prevalence of localized aggressive periodontitis (LAP), clinical characteristics of LAP in primary dentition are derived from a few case reports/series in the literature. The goal of this study was to determine common clinical characteristics such as bone and root resorption patterns, in a series of cases with LAP in primary dentition. We hypothesize these cases present aggressive periodontal bone destruction starting mostly around first primary molars and atypical root resorption patterns. Study Design: We have evaluated 33 LAP cases in primary dentition for pattern of bone destruction, root resorption and early exfoliation. Results: Cases evaluated were aged 5–12 (mean=8.7 years). Thirty cases presented more severe bone loss on first than second molars, with relatively fast progression to second molars, altered pattern of root resorption, mostly external (n=16) and early exfoliation of primary teeth due to periodontal bone loss, rather than physiologic root resorption (n=11). Conclusions: This study showed common clinical characteristics found in LAP in primary molars, including possible initiation on first primary molars and abnormal root resorption patterns. These characteristics are important to be early identified and treated in order to prevent possible progression into the permanent dentition.
Periodontal Pathogen Colonization in Young Children by PCR Quantification – A Longitudinal Survey
Authors: Takahashi Karine , Cunha Robson Frederico , Junior Elerson Gaetti Jardim
Published: October 2017

Introduction: Periodontal diseases are among the leading causes of premature tooth loss in adults, but the microbiota associated with this problem is established over time in childhood. Aim: This longitudinal study aimed to verify the occurrence of periodontal pathogens in the oral cavity of children aged six, twelve, eighteen and twenty-four months through PCR quantification, correlating them with the oral microbiota of their mothers. Study design: Saliva and oral biofilm samples were collected from mothers and children by using sterilized paper points. Furthermore, a questionnaire was applied in all periods to evaluate hygiene and dietary habits. Results: A positive correlation was found between mother–child pairs in all periods. No correlation was observed between hygiene and dietary habits and occurrence of periodontal pathogens. Conclusion: Early inclusion of children in preventive and biofilm control programs could contribute to preventing acquisition of aggressive pathogens.

Published: October 2017

Objective: This study estimated the prevalence, extent, buccal distribution and associated factors involving enamel defects in Brazilian schoolchildren. Study design: A cross-sectional study using a multistage cluster random sample of 1,206 8–12-year-old Brazilian schoolchildren was carried out in Pelotas, Brazil. The prevalence of enamel defects in the permanent dentition was determined using the modified Developmental Defects of Enamel index (DDE). Sociodemographic and health data were collected from their mothers using a semi-structured questionnaire. Data were analyzed using Poisson regression modelling for DDE prevalence and negative binomial regression modelling for the extent of DDE. Results: The prevalence of any enamel defects was 64.0% (95% Confidence Interval: 61.4, 67.0); the main types were diffuse opacities (35.0%), demarcated opacities (29.5%) and hypoplasia (3.7%). In general, older children had a lower prevalence and extent of enamel defects than their counterparts (p<0.001). There were no other significant associations. Conclusion: Enamel defects are common, especially among younger children, but the role of pre-, peri- and postnatal exposures remains unclear.

Published: October 2017

In this birth story, Katherine shares that she wanted an unmedicated birth. She planned a hospital birth with a midwife. During her pregnancy, she hired a doula and she and her husband, Corey, attended both natural childbirth classes and a natural comfort measures class. Katherine had an intense labor but was able to relax between contractions, and with the support of her husband and doula, she managed to cope with increasingly difficult contractions. Her commitment and hard work during labor, and the emotional and physical support she received, helped her achieve the unmedicated birth she wanted. Katherine and her husband welcomed their daughter, Clara Mae, into the world after 10.5 hours of labor.

Published: October 2017

Introduction: The Integrated Programme of Maternal and Child Health aims to reduce maternal and child mortality in Guinea-Bissau. The purpose of this article is to share our experience in building a training programme on maternal and newborn care for health-care professionals in Guinea-Bissau.Material and Methods: Regional directors of the four target areas chose a group of staff who provide prenatal and childbirth care to attend the course (12 to 15 trainees per region). In each region, 15 highly interactive and practical sessions were scheduled over eight weeks. The trainees’ summative and reactive assessment was obtained using a multiple choice questionnaire (final test) and an anonymous survey, respectively.Results: Attendees included 25 nurses, 17 midwives and 14 doctors. About two thirds had five years’ practice or less. Test median scores were higher among trainees with two to nine years of practice (54.4% to 60.9%), as compared to those with a year or less (47.8%) or 10 or more years (45.7%). Pedagogical variables were rated as ‘good’ or ‘very good’ by 91% to 95% of the attendees.Discussion: Use of an interactive and practical pedagogical methodology produced positive results and was crucial to tailoring the training to local needs. However, adapting the syllabus according to professional categories and experiences should be considered.Conclusion: Our results warrant further development and evaluation of training programmes on maternal and neonatal care in Guinea-Bissau.
Análise da Revisão Cochrane: Suplementação Alimentar com Ácidos Gordos Ómega-3 no Tratamento da Demência. Cochrane Database Syst Rev. 2016;4:CD009002.

A suplementação alimentar com ácidos gordos poli-insaturados ómega-3, de origem animal e vegetal, é comummente prescrita como alternativa não farmacológica no tratamento da demência, com o objetivo de atrasar a sua progressão e melhorar a função cognitiva dos doentes. Esta utilização deriva em grande medida de estudos pré-clínicos, que estabeleceram o papel dos ácidos gordos poliinsaturados ómega-3 no desenvolvimento e manutenção da integridade do sistema nervoso central, e de estudos epidemiológicos, que demonstraram a ocorrência de estados de malnutrição em doentes com demência. Nesta revisão sistemática Cochrane, os autores incluíram três ensaios clínicos aleatorizados controlados por placebo, com baixo risco de vieses, nos quais doentes com doença de Alzheimer ligeira a moderada foram tratados com ácidos gordos poli-insaturados ómega-3, através de suplementos alimentares. Dos principais resultados desta RS destacam-se a ausência de evidência de um efeito benéfico do tratamento com suplementação com ácidos gordos poli-insaturados ómega-3 sobre a função cognitiva de doentes com doença de Alzheimer e a baixa taxa de efeitos adversos reportados, esta última comparável à dos grupos tratados com placebo. Não existem dados sobre outros tipos de demência. Neste artigo sumarizam-se e discutem-se os principais resultados e conclusões desta revisão sistemática, bem como as suas implicações para a prática clínica diária.

Precision machining of sintered zirconia ceramics is expected for various applications such as dental prostheses or artificial femoral heads. However, machining of zirconia is a major challenge because of its high hardness. We have found that the bending strength and fracture toughness of this material decrease with an increase in temperature. To use this characteristic, we propose a high-speed milling process with a cutting speed of more than 500 m/min because high-cutting speed can generate a large amount of heat during cutting. According to the results of trials, precision machining of the surface was possible with a cutting speed of 670 m/min. Moreover, the amount of flank wear was decreased by the high-speed milling. These results confirmed the possibility of precision cutting of sintered zirconia ceramics.
Transfer-Print of CNTs and its Application to Cell Scaffold
Authors: Kaneko Arata ,   Faculty of System Design, Tokyo Metropolitan University 6-6 Asahigaoka, Hino, Tokyo 191-0065, Japan, Miyazaki Yuuki , Goto Tatsuya
Published: October 2017

A bio-chip using cultured cells is developed for an application to drug screening. Carbon nanotubes (CNTs) are a candidate for this electrode material. A transfer-prints is expected to be a CNT-patterning technique applicable to soft material. This present paper is intended to show some basic properties about the transfer-print of CNTs, and also to demonstrate the possibility of the CNTs as a cell scaffold. The present study prepared several types of surface-modified Si substrate with different wettability to investigate the effects of wettability on the transferring ratio of CNTs. Some Si substrates are terminated by OH or H groups, while other substrates are coated with hydrophobic or hydrophilic self-assembled monolayers. The stamps for transfer-print, which have circular dots (50-μm diameter) or a straight ridge (50-μm width) array, are fabricated using poly-dimethyl-siloxane (PDMS). The surfaces of PDMS stamps are inked by single-walled CNTs by a pre-transferring or casting process. The transfer-prints to surface-modified Si surfaces allow the CNTs to be formed in lines of several tens of micrometers, while the coverage of transfer-printed CNTs is also dominated by surface wettability. The coverage of transfer-printed CNTs increases with the water contact angle of the Si surface. It is reasonable that the transfer-print of CNTs is performed by hydrophobic interactions. Meanwhile, two kinds of polymer (polystyrene (PS) and polyethylene terephthalate (PET)) sheets are also utilized as a substrate. The transfer-prints with heating around the softening point of the polymer allow CNTs to be accurately patterned into an array of 50-μm dots. The coverage of CNTs is 94% on the PET substrate. The PS sheet with patterned CNTs is applied to a cell scaffold. PC12 cells are cultured on the PS sheets so that the cells are selectively adhered to the transfer-printed CNTs. The adhered cells are extended with some pseudopods. It is demonstrated that the transfer-printed CNTs are expected to be electrodes of the cell scaffold.

Recently, the aviation, shipping, and energy industries have been using components that are more thin-walled. Deformations occurring during the cutting of these thin-walled components could lead to dimensional errors. This paper describes a finite element method that requires fewer processes and less processing time than other methods, developed to predict the deformation of workpieces during their cutting. Using this method in conjunction with cutting simulations allows for the analysis of workpiece deformations through the modification of stiffness matrices containing information from cutting simulations, rather than recreating meshes or stiffness matrices. Moreover, part of the processing makes use of an accelerated method of solving simultaneous equations using large scale parallel computations with GPU.
Development of an Injection Mold Capable of Melt Flow Control and Induction Heating and Cooling

Weldlines are a type of defect in polymer injection molding and are known to impair the appearance and mechanical strength of the molded product. A previous study involved designing and fabricating an induction heating and cooling mold that incorporates an induction coil, allowing it to rapidly heat up. The study verified that the use of this mold prevents weldlines and improves the surface properties of the molded product. Although it is possible to prevent impairment of the external appearance caused by weldlines or the exposure of glass fibers on the surface when the mold is applied to glass fiber reinforced thermoplastic, the results of the previous study indicated that it did not significantly improve the mechanical strength. Hence, the present study involved designing and fabricating an injection mold capable of melt flow control in addition to induction heating and cooling by incorporating a melt flow control mechanism that employs a movable core pin to control the flow direction in the mold used in the previous study. The mold is used to form samples of short- and long-glass fiber reinforced polypropylene while simultaneously performing heating and cooling and melt flow control to obtain samples with smooth flat surfaces in which the exposure of glass fibers is prevented while exhibiting increased bending strength.

Published: October 2017

Loss of pregnancy either naturally or by medical termination is a destructive experience to the couple, especially those experiencing recurrent pregnancy losses (RPL). It is important to rule out the genetic aspect as the cause of pregnancy wastages. This retrospective study aimed to determine the frequency of chromosomal abnormalities and its various cytogenetic types in the samples received by Metropolis Healthcare laboratory, Mumbai. This study was conducted on the samples referred for chromosomal karyotyping with a history of Bad Obstetric History (BOH). The couples who had an experience of two or more pregnancy losses were included in this study. Out of the 2102 samples referred, chromosomal abnormality was recorded in 384 (18.27%) cases. Out of chromosomal abnormal cases, 126 (5.99%) patients had reciprocal translocations out of which 27 (21.43%) were Robertsonian translocations. Inversion of chromosome 9 was seen in 81 (21.09%) patients, while inversion Y in 28 (7.29%) patients,  and polymorphic variation like increase in length of satellite or heterochromatic region recorded in almost 149 (38.30%) patients. Cytogenetic evaluation of couples with recurrent pregnancy losses (RPL) is very important as after knowing the parental chromosomal pattern appropriate counseling can be offered to know the risk of recurrence, option of prenatal diagnosis and also opens the option of reproduction in some cases. This will also help them to have a cytogenetically healthy baby. Since the cytogenetic abnormalities are usually familial, the close blood relatives may also be benefited once the abnormality is detected.

At present, titanium and its alloys stand out for their mechanical and biological properties. Vickers hardness and the effect of 15%, 22% and 35% hydrogen peroxide (H2O2) on Ti-10Mo alloy corrosion were evaluated. A conventional double-walled glass cell was used for thermostatization. As reference electrode was used the Ag/AgCl (s)/KClsat and as auxiliary electrode graphite stick. The work electrodes consisted of Ti-10Mo cylinders embedded in polyethylene, with electrical contact by brass wire and silver paint on one end. The electrolyte used was H2O2 in concentrations of 15%, 22% and 35% and potentiodynamic measurements were recorded. The Vickers hardness was evaluated before the treatment using Vickers penetrator under load of 1000g and dwell time of 10s / measurement separately. The results showed an increase in the corrosion values in direct relation with the increase of the H2O2 concentration. At 35% concentration, at constant current of ~ 1.0V the alloy did not passivate, characterizing high corrosion rate. At the concentrations of 15% and 22% the results showed a tendency to pseudopassivation, with release of TiO2 and part of the product of the corrosion becoming semi-adherent to the surface of the working electrode and another part passing through the middle, characterizing intermediate corrosion velocity. It was concluded that higher H2O2concentrations produced higher electrochemical corrosion.Descriptors: Titanium; Alloys; Surface Properties; Corrosion; Tooth Bleaching Agents.

Feedback from employers, internship supervisors, and graduate schools tells us that we are doing a good job of teaching students academically/technically, but our graduates require greater training in communications, critical thinking/problem solving, and leadership/management. Because of their long-term importance to our graduates, we call these “career skills.” To address this issue a task force was established, and over a 2-year period, this group defined the College of Agriculture and Life Sciences [CALS (University of Arizona, Tucson)] Students Career Skills Competencies and vetted them through college faculty and more than 50 companies. We divided the CALS Student Career Skills Competencies into three categories: 1) communication skills, 2) critical thinking/problem solving skills, and 3) leadership/management skills. We are currently asking each degree-granting unit in the college how they do, or will, incorporate these competencies into their curricula, with the idea of incorporating the competencies into existing courses first, to avoid increasing the number of required credit hours for graduation and time to degree. Our goal is that by graduation, each student should have had multiple opportunities to hone each of these competencies.
Identification of Industry Needs and Development of Professional Skills in Students of Horticulture
Authors: Pearson Brian J. , Moore Kimberly
Published: October 2017

Increased global trade coupled with diversified employment opportunities demand college graduates possessing well-developed professional skills. Recent survey results identified the importance of professional skills among candidates seeking employment, with communication being recognized as the most important skill or quality when selecting candidates. The ability to work within a team structure, solve complex problems, and organize and prioritize work also ranked high among industry employment needs. Despite a rigorous focus on discipline-oriented knowledge and skills, development of professional skills in students of horticulture may be overlooked or not fully developed. Teaching methods can be modified to incorporate development of professional skills and discipline-oriented knowledge to enhance student employment preparedness and directly address industry needs.

Eleven hazelnut (Corylus avellana) cultivars, four Spanish (Clon La Masó, Negret N-9, Negret Primerenc, and Pauetet), four Italian (San Giovanni, Tonda Italiana, Tonda di Giffoni, and Tonda Romana), and three cultivars from Oregon State University’s (OSU) breeding program (Clark, Lewis, and Willamette), were evaluated in northeastern Spain over a period of 15 years (2001–14). The trial was planted at the Institute of Agriculture and Food Research and Technology (IRTA)-Mas de Bover Station (Constantí, Spain) in 2001, using own-rooted material, in single-trunk, 6 × 3.5-m spacing, and fitted with drip irrigation. Tree vigor, sucker production, early bearing, and total crop were recorded during the first 9 years. Nut traits were studied over 7 years and nutritional composition analyzed in 3 years. The best agronomic performance was observed in ‘San Giovanni’, ‘Pauetet’, ‘Clon La Masó’, and ‘Tonda Italiana’ that scored the highest total crop and canopy volume, but ‘San Giovanni’ and ‘Clon La Masó’ produced a high number of suckers. The best industrial value of the kernel was given by ‘Tonda di Giffoni’, ‘Negret N-9’, ‘Willamette’, and ‘Clark’ with high roasting aptitude and high fat content, although ‘Negret N-9’ was a little poor in monounsaturated fatty acids. The three cultivars from the Oregon breeding program had good agronomic behavior and industrial potential, but were not an improvement on the traditional Mediterranean cultivars.

Turfgrass species can be classified into two main groups: cool-season and warm-season species. Warm-season species are more suited to a Mediterranean climate. Transplanting is a possible method to convert a cool-season to a warm-season turfgrass in untilled soil. It generally requires the chemical desiccation of the cool-season turfgrass. However, alternative physical methods, like flaming and steaming, are also available. This paper compares flaming, steaming, and herbicide application to desiccate cool-season turfgrass, for conversion to hybrid bermudagrass (Cynodon dactylon x C. transvaalensis) in untilled soil, using transplanting. Two prototype machines were used, a self-propelled steaming machine and a tractor-mounted liquefied petroleum gas flaming machine. Treatments compared in this work were two flaming treatments and two steaming treatments performed at four different doses together with two chemical treatments with glufosinate-ammonium herbicide applications. The cool-season turfgrass species were tall fescue (Festuca arundinacea) and perennial ryegrass (Lolium perenne). The desiccation effect of the various treatments on cool-season turf was assessed by photographic survey 15 days after treatment. The percentage cover of hybrid bermudagrass was visually assessed at 43 weeks after planting. Steaming and flaming effects on both parameters were described by logistic curves. The highest doses of steaming and flaming almost completely desiccated cool-season turf, and similar hybrid bermudagrass cover was established by both the methods as the chemical application (50% to 60%). Thus both flaming and steaming may be considered as valid alternatives to herbicides aimed at turf conversion.

Landscape plant evaluations were conducted in eight states: Colorado, Minnesota, North Carolina, Ohio, Oregon, Pennsylvania, Texas, and Vermont for 17 switchgrass (Panicum virgatum) and five little bluestem (Schizachyrium scoparium) cultivars. Additional locations in Florida (Fort Lauderdale, Fort Pierce, Quincy, and Wimauma), Nebraska (Lincoln), and Lubbock and San Marcos completed 1 or 2 years of the trials. Plants were established in 2012 and data were collected for 3 years, 2013–15. Sites were asked to compile annual data on plant height, width, flowering time, fall color, pests, foliage color determined by the Royal Horticultural Society’s color chart, plant form, flowering date, floral impact, self-seeding, winter injury, landscape impact, and mortality. Texas A&M Agricultural Research and Extension Center (Overton), Florida (all four locations), and Vermont had the highest mortality rate. Southern Florida locations lost 50% of their plants by the end of 2014. Wide variation was reported for landscape impact, individual cultivar height, and width from different regions of the United States. Three of the 17 switchgrass cultivars, Cloud 9, Northwind, and Thundercloud, had a rating of 4.0 or higher averaged over six or more locations for plant form, floral, and landscape impact. ‘Shenandoah’ and ‘Warrior’ switchgrass had a rating of 4.0 or higher averaged over six or more locations for plant form and landscape impact, but not floral impact. Only one of the five little bluestem cultivars, Blue Heaven® rated 4.0 or higher, for plant form and landscape impact when averaged over six or more locations. This range of variability in landscape plant performance demonstrates the importance of local plant evaluations.
Hands-on Horticulture: A Course for Building Enrollments in Plant Science Courses
Authors: Pritts Marvin P.
Published: October 2017

A course was developed at Cornell University for the purpose of attracting nonmajors from across the university, instilling in them an appreciation for horticulture and then encouraging them to take additional horticulture and plant science courses. The course incorporates many engaging and interesting horticultural activities, with scientific concepts and horticultural techniques conveyed almost exclusively through hands-on instruction using the campus as a laboratory. Experiential learning and culinary experiences are key components of the course. Student evaluations are very high (5-year average of 4.94/5.00 with five representing “excellent”), and the class fills to capacity each spring semester with diverse students from across campus. Enrollment in other horticulture classes has increased since the course has been offered. Forty-three percent of students who took Hands-On Horticulture as a freshman, sophomore, or junior subsequently enrolled in at least one other plant science course. Participating horticulture faculty also find the class to be fertile ground for recruiting research and field assistants. Students report an increase in well-being and reduction in stress while taking the course, and write about how their worldview has changed after the course experience. This class has allowed students to discover or rediscover their role and connection to nature while simultaneously providing them horticultural skills and understanding of scientific principles.
