Bond strength prediction for plain bars under lateral tensile compressive stresses
Authors: Zhang Xue , Fan Xing-lang , Dong Wei , Ou Jin-ping
Published: October 2017

The bond strength of plain bars plays an important role in assessing the anchorage capacity of historical buildings. For plain bars, the bond strength greatly depends on the frictional effect, and can easily be affected by the lateral stress around the bars. For bars located in the beam–column joint, the lateral compressive–tensile stresses from gravity and earthquakes might be applied simultaneously. To date, the effect of such biaxial stresses on the bond strength of plain bars has not been evaluated in an analytical manner. Consequently, an analytical approach combining both theoretical and numerical solutions to the bond strength of plain round bars under biaxial tensile compressive stresses is developed. Comparison between test data and the results calculated by the proposed analytical model shows that the model is well capable of predicting the bond strength for different concrete and bars. Moreover, the comparative studies between the proposed analytical model and closed-form solutions show that the partial separation of the bond interface due to the biaxial stresses cannot be ignored in predicting the bond strength of plain bars. Finally, a simplified model with acceptable precision is suggested to substitute for the numerical procedure in the proposed analytical model.

Authors: Primi Stefano , Paulotto Carlo , Llago Acero Ricardo , Calvo Herrera Ignacio
Published: October 2017

This paper describes the design, manufacture, installation and load testing of a 40 m long urban footbridge over the River Manzanares in Madrid, Spain. The main structure of the footbridge consists of a fibre-reinforced polymer girder. The girder was manufactured in a workshop using the resin-infusion process, which is normally used to manufacture fibreglass boat hulls. Potential problems that can arise in the manufacture of such elements are highlighted in the paper and the strategies adopted to cope with them are illustrated. The girder was transported by truck to the site where it was lifted onto reinforced concrete supports. The results of the static and dynamic load tests carried out after completion of the pedestrian bridge are presented.

A espécie Symphysodon aequifasciatus é uma das espécies de peixe ornamental de grande importância econômica no comércio nacional e internacional, no entanto, pouco se sabe sobre seus aspectos fisiológicos e sanitários dessa espécie em cativeiro. Nesse sentido, o objetivo do presente estudo foi determinar o perfil hematológico basal do acará disco mantido em cativeiro. Para isso, 14 animais adultos selvagens foram aclimatados em condições laboratoriais semelhantes às condições ambientais. O sangue dos peixes foi retirado por punção da veia caudal para as análises eritrocitárias, trombocitárias e leucocitárias. O resultado do hemograma mostrou maior frequência de linfócitos e ausência de eosinófilos, basófilos e LG-PAS, semelhante a resultados obtidos por outras espécies da família Cichlidae descritos na literatura. Não foi observada mortalidade indicando adaptação às condições de cativeiro refletido pelo exame sanguíneo normal.

Authors: Rangel Etuany Martins Rangel , Gomes da SIlva Muylaert Monteiro de Castro Bianca , Pereira de Moraes Luciana
Published: October 2017

O presente artigo, mediante revisão bibliográfica, pretende verificar o impacto da masculinidade na saúde do homem na atualidade, articulando categorias-chave como gênero, masculinidade e saúde. Assim propomos uma análise do tema, com objetivo de averiguar até que ponto a masculinidade interfere no processo saúde-doença do homem, salientando os comportamentos socioculturais existentes durante a fase da adolescência que refletem na saúde do indivíduo na fase adulta. Associado a isto, buscar-se-á analisar e discutir como a Política Nacional de Atenção Integral à Saúde do Homem, formulada em 2009 pelo Ministério da Saúde, destinada a qualificar e efetivar a integralidade no direito à saúde, e geradora de ações de saúde que contribuam significativamente para a compreensão da realidade masculina em seus diversos contextos socioculturais e político econômicos, buscando romper obstáculos que impeçam os indivíduos do sexo masculino de frequentar os serviços de saúde. Dessa forma, buscaremos entender como a construção social do gênero masculino interfere nos cuidados da saúde do homem.
A UM PASSO DA BRANQUITUDE: O QUE DIZEM OS CORPOS DAS MULATAS BRASILEIRAS?
Authors: Craveiro Camila , Carvalho Claudia
Published: October 2017

O presente artigo se propõe a discutir a intersecção das matrizes de raça – classe – gênero na sociedade brasileira a partir da figura da mulata, símbolo de beleza tropical e sensualidade. Para tanto, o caminho percorrido retorna à miscigenação que deu origem ao povo brasileiro, passa pela desconstrução do mito da democracia racial, em contraposição aos processos de branqueamento da população, alcançando o racismo corporificado na mulata, cujo corpo é percepcionado como objetificado, sexualizado e disponível. A análise privilegia a perspectiva feminista e descolonial ao questionar as posições de sujeito que as mulatas desempenham na sociedade brasileira.
A EXPERIÊNCIA DA ORGANIZAÇÃO DAS MULHERES INDÍGENAS DE RORAIMA: UMA REFLEXÃO SOBRE MULTICULTURALISMO A PARTIR DAS CONTRIBUIÇÕES DE SUSAN OKIN
Authors: LIMA NATHALIA FERNANDES , MODERNELL BARBARA DANIELLA LAGO , DE ANDRADE DENISE ALMEIDA , DA SILVA SOLANGE TELES
Published: October 2017

O presente artigo tem como objetivo, a partir dos conceitos de gênero, público e privado e multiculturalismo, compreender a proposta de Susan Moller Okin sobre a incompatibilidade entre feminismo e multiculturalismo, considerando-se a experiência da organização das mulheres indígenas de Roraima. Partiu-se da construção social do gênero e suas implicações na divisão desigual do trabalho, para entender como isso contribuiu para a divisão das esferas público e privado, e manutenção da sociedade patriarcal. Buscou-se compreender como essa divisão afeta o direito das mulheres em grupos minoritários, por meio de uma análise sobre o movimento das mulheres indígenas no Estado de Roraima, no norte do Brasil, bem como apontar uma alternativa para o problema apresentado por Okin. Por fim, entende-se ser igualmente necessárias a proteção da identidade dos grupos minoritários e a garantia de espaços igualitários nos grupos minoritários étnicos. Desta forma, a inclusão das mulheres nos espaços de poder e tomada de decisão nestes grupos deve ser compatibilizada com o respeito à relevância que essa mulher confere ao seu pertencimento ao grupo.
A MEDIAÇÃO COMO DIREITO FUNDAMENTAL E ACESSO À JUSTIÇA
Authors: Dalto Natália Pereira
Published: October 2017

O presente trabalho visa refletir sobre uma prática

ainda pouco utilizada no Brasil como meio de resolução

de conflitos e que pode auxiliar na construção de

uma sociedade mais consciente de seus direitos humanos,

onde os cidadãos possam vivenciar a justiça e

a democracia. A mediação como direito humano fundamental

e acesso à justiça onde o cidadão através

do próprio empoderamento tem a oportunidade de

resolver seus conflitos através de técnicas desenvolvidas

por um terceiro imparcial e escolhida pelas partes.

O acesso à justiça é direito humano e essencial ao

completo exercício da cidadania. Mais que acesso ao

judiciário, alcança também o acesso a aconselhamento,

mediação, conciliação, consultoria, enfim, justiça

social, orientando as partes a alcançarem a resolução

de seus conflitos. Precisa-se destacar, entretanto,

que o acesso à justiça, garantido pela Carta Magna,

é um direito e, não, um dever do cidadão de provocar

o Poder Judiciário para debelar todos os conflitos de

interesses surgidos das interações entre os indivíduos

na sociedade. Estabelecida essa premissa, impõe-se

uma mudança de cultura dos sujeitos de direito objetivando

prestigiar os métodos auto compositivos,

como a mediação e a conciliação, como meios adequados

para se dirimir os conflitos de interesses no

Estado Democrático de Direito. Este artigo tem objetivo

de contribuir para a formação de estudantes e

pesquisadores pela justiça e equidade social.

Published: October 2017

Esta pesquisa tem como objetivo investigar a utilização das sociais Facebook e Linkedin por Docentes dos Programas de Pós-Graduação (PPG) classificados pela CAPES na Área de Engenharias III. O método aplicado foi a Mineração de Dados (MD) de Regras de Associação (RA), com o uso do algoritmo Apriori, através do ambiente de MD WEKA. Constatou-se que 85,87% dos docentes são do gênero masculino, 25,03% dos docentes possuem conta no Linkedin ou Facebook; 17,91% dos docentes possuem o Linkedin; e 11,76% dos docentes possuem conta no Facebook. Quanto as ocorrências de postagens no período investigado, 43,48% dos perfis postaram fotos ou imagens de trabalho; e apenas 13,04% postaram vídeos de trabalho. Conclui-se que o uso das redes sociais por docentes para fins educacionais são é incipiente e que as postagens são predominantemente relacionadas ao lazer. Infere-se assim que a rede social ainda não teve o reconhecimento por parte dos docentes do seu potencial no processo de ensino aprendizagem.

Urban Concentration and Spatial Allocation of Rents from natural resources. A Zipf's Curve Approach
Authors: Dentinho Tomaz Ponce
Published: October 2017

This paper aims at demonstrating how countries' dependency on natural resources plays a crucial role in urban concentration. The Zipf's Curve Elasticity is estimated for a group of countries and related to a set of indicators of unilateral transferences. Results show that in comparison to others, countries with higher urban concentration explained by higher Zipf's Curve Elasticity have a higher percentage of income coming from natural resources and education expenditures whereas public spending in health and outflow of Foreign Direct Investment seem to have spatial redistribution effects. Summing up, there are signs that the spatial allocation of property rights over natural resources and related rents influences urban concentration.

Authors: Stankevich Alina
Published: October 2017

In the last years, research investigating consumer behaviour and how their decision-making process has advanced and has become an important topic in the marketing society and literature. To advance the research further, this paper presents an extensive literature review of academic publications in the area of buying decision-making process in marketing and its status. Furthermore, the paper presents latest trends and themes that emerge there. Based on 24 journal articles, reports and marketing books, the core models and theories in this area were evaluated and discussed. Moreover, a framework of “moments that matter” in consumer decision-making process and factors that influence them was elaborated for a possibility to influence consumer behaviour in favour of company’s offers. Furthermore, recommendations for marketers were suggested for deeper understanding the consumer behaviour and their buying strategies to empower marketing campaigns and be a success in the market. The paper also suggests several directions for future research related to buying behaviour.
A Critical Risk Analysis of Absenteeism in the Work Place
Authors: Badubi Reuben Mokwena
Published: October 2017

This study seeks to validate the fact that there is a problem of absenteeism amongst employees in different workplaces and analyzes the impact of a persistent absenteeism by employees on the organization. Employees can be absent at work for various reasons or just deciding to be rebellious as a sign of registering some concerns especially associated with job dissatisfaction in the workplace. Absenteeism in the workplace is catastrophic as it hinders performance and results. Organisations, therefore, should put mechanisms in place that would be geared towards curbing this rampant attitude that should not be entertained. The researcher in this article, based on a narration and assembly of several kinds of literature, explore and expound the types of absenteeism and what influences employees to stay away from work as well as solution to arrest the situation. There is a need for management to countermeasure issues of absenteeism because they impact negatively to the finances, an image of the organization and derail progress too. A qualitative approach was considered when compiling this paper in order to analyse the topic.
Meeting energy requirements in pig nutrition
Authors:   Iowa State University, USA, Patience J. F.
Published: October 2017

The level of energy in a pig’s diet influences the rate and efficiency of gain, the quality of the resulting carcass and even the quality of the pork produced from the carcass. However, energy requirements and energy use in pigs are not well understood, due to the complexity of the topic. Unlike nutrients in the diet, energy is supplied by numerous dietary constituents, and each of these is utilized as an energy source in different ways and in accordance with their metabolic fate. This chapter will discuss the basics of energy metabolism, energy systems, energy sources, energy requirements and methods to improve the utilization of energy by the pig.

Dessacralizando as propriedades: um estudo sobre o aforamento urbano e a mentalidade proprietária do início do século XX em Natal (RN)
Authors: Siqueira Gabriela Fernandes
Published: October 2017

Este artigo objetivou analisar a política de apropriação do solo urbano do terceiro bairro de Natal entre 1901 e 1919, bem como os usos que os sujeitos fizeram desse solo. No período estudado, os sujeitos apropriavam-se do solo urbano de Cidade Nova por meio do instituto do aforamento. Pretende-se investigar as leis federais e estaduais que definiram o aforamento, relacionando-as com as resoluções que regulavam as enfiteuses existentes em Natal e, sobretudo, em Cidade Nova no período estudado. Com esse estudo pode-se demonstrar como a capital do estado que iniciou o século XX com discursos progressistas continuou com uma política de terras tradicional, exemplificando como a mentalidade proprietária moderna não foi plenamente estabelecida em Natal no período estudado.
O Rio de Janeiro de 1860 pela revista Semana Ilustrada: o progresso, os espaços públicos e os trabalhadores.
Authors: Pereira Renan Rivaben
Published: October 2017

No início da década de 1860, com os lucros do café e a supremacia do poder senhorial, o Império do Brasil aspirava prender-se de vez na rabeira do progresso. No Rio de Janeiro, os homens, vestidos “à inglesa”, e mulheres, à moda francesa, aperfeiçoavam os seus requintes pelas maisons francesas que se multiplicavam pela afamada Rua do Ouvidor. A nova folha ilustrada da Corte, a Semana Ilustrada (1860/1876), consumida por estes que, admiravam as óperas italianas e riam nas peças cômicas no teatro Ginásio, não raras vezes reprovava as condições físicas e morais das áreas urbanas da cidade e daqueles que não frequentavam os bailes do Clube Fluminense e do Botafogo, como as quitandeiras das praças de comércio, as lavadeiras do Campo de Sant’ana e os vendedores ambulantes e pretos de ganho da estação ferroviária D.

The wide implementation of social networking sites (SNS) in many fields, for instance, government, celebrities, schools, social groups, events promoted by national organizations or private enterprises, NPOs, businesses, etc., attests to its popularity. Currently more and more educators and students have integrated these online social communication platforms into their learning environment. Learning Management Systems (LMS) also have great features and functions that may serve as a bridge between learners and educators leading to better communication, in addition to helping students increase their learning engagement and teachers in evaluating learning performance. Although many studies have investigated the effects of adopting Facebook as an additional learning management system (LMS), its functions and benefits differing from the LMS have hardly been systematically analyzed. Besides, due to the increasing popularity of mobile devices among the younger generation, university students are obviously likely to use their smart phones to access both Facebook Mobile App and school LMS. Therefore, the first purpose of this study is to determine students’ opinions on mobile Facebook course groups and a mobile LMS course group, through a survey conducted after a 2-semester experiment. The other objective of this study is to evaluate the benefits of each function of mobile FB course groups that may strengthen the current weaknesses of LMS. In addition, regression analysis and t-test were used to reveal the relationships among variables: the FB functions and its benefits for FB course group. The findings might provide a clear notion for teachers regarding the functions and advantages contributed by a mobile FB course group which can be implemented as a supplemental learning system. The results of the research will provide university administrators with more detailed information for improving the LMS’ features or developing new LMS Apps.

Published: October 2017

Many missions have been launched to explore the Moon, Mars, asteroids, and comets, and many researchers are studying and developing lunar and planetary rovers for unmanned planet exploration, and further cooperative missions targeting human lunar exploration are under discussion. A key technology in these missions and orbital services is space robotics, including Al and automation. Space robotics is expected to support external vehicular activities (EVA) and internal vehicular activities (IVA), which will include constructing, repairing, and maintaining orbiting satellites and space structures.

This special issue presents the updated mission results and advanced research activities of space organizations, institutes, and universities, although it does not include all. We hope that this special issue will be useful to readers as an introduction to advanced space robotics in Japan, and that more robotics and Al researchers and engineers will become interested in space robotics and participate in space missions.

We thank the authors for their fine contributions and the reviewers for their generous contributions of time and effort. In closing, we also thank the Editorial Board of the Journal of Robotics and Mechatronics for helping to make this issue possible.
Evaluation of Spring and Fall Fungicide Applications for Large Patch Management in Zoysiagrass
Authors: Obasa Ken , Fry Jack , Bremer Dale , Kennelly Megan
Published: October 2017

The efficacy of spring and fall applications of azoxystrobin, flutolanil, and triticonazole for the control of large patch disease of zoysiagrass (Zoysia spp.) caused by Rhizoctonia solani Kühn AG 2‐2 LP were evaluated under field conditions. The study was conducted on fairway stands of ‘Meyer’ zoysiagrass from 2008 to 2010 at the Rocky Ford Turfgrass Research Center, Kansas State University. Experimental plots were inoculated prior to the start of the studies. All fungicide applications were made with a CO2–powered boom sprayer with XR Tee Jet 8003VS nozzles at 206.8 kPa in water equivalent to 816 L ha−1. Disease assessment was performed by measurement of patch diameters, visual assessment, and by analysis of digital images of affected plot areas. In general, two fall applications of fungicide did not reduce disease compared with one fall application. Fall applications made when thatch temperatures ranged from 17.8 to 23.2°C reduced disease relative to untreated controls. Similarly, two spring applications of fungicide, beginning at an early curative timing, did not reduce disease compared with one spring application.
Organic Fertilizer Deters Vertebrate Pests from White Grub‐Infested Turf
Authors: Williamson R. Chris , Obear Glen R.
Published: October 2017

Soil‐dwelling white grubs cause damage by feeding on turf roots, but vertebrate predation of grubs can cause extensive damage, even at low population densities. As a result, golf course superintendents may use insecticides to reduce white grub populations regardless of population densities. This research explores the potential to deter vertebrates from white grub‐infested areas by applying Milorganite, a turf fertilizer derived from human biosolids. The study was conducted on rough‐height Kentucky bluegrass (Poa pratensis L.) at two different golf courses in Wisconsin in 2008. The fertilizer was applied once at 16.1 or 48.8 kg N ha−1, and vertebrate damage was rated weekly for 4 wk. All control plots received some damage from vertebrate predation. The high and low rates of Milorganite reduced damage from vertebrate predation compared with the nontreated control, but there were minimal differences between rates. These findings suggest that biosolid‐based fertilizers may deter vertebrate predators of white grubs and could provide an alternative to insecticide treatment. The feasibility of this practice remains unclear and would depend on the residual efficacy and required reapplication interval of the products applied.
Effect of Soil Texture and pH on Amicarbazone Persistence
Authors: Gannon Travis W. , Jeffries Matthew J. , Ahmed Khalied A.
Published: October 2017

Amicarbazone is a photosystem II‐inhibiting herbicide utilized for weed species in turfgrasses. Amicarbazone is highly water soluble, has a low soil organic carbon–water partition coefficient, and does not dissociate. Although previous research suggests that amicarbazone persistence may range widely, it has been reported to be very short in acidic soils and moderately persistent in alkaline soils. Laboratory experiments were completed to evaluate the effect of soil pH on amicarbazone persistence and sorption in Drummer loam, Lubbock sandy loam, and Cecil sandy clay loam soils. Amended and unamended soils were included within each experiment for comparison. Amicarbazone persistence ranged widely (9–117 d) due to soil texture and pH and was more persistent under alkaline soil conditions. Under acidic conditions, amicarbazone was more persistent in loam and sandy loam (half‐life, T1/2 = 57 d) compared with sandy clay loam (T1/2 = 9 d), while less difference was noted under alkaline conditions. Calculated sorption coefficients were comparable, suggesting that persistence across soil textures and pH is not solely due to differential sorption. Turfgrass managers should be cognizant of soil pH and texture, as they may affect persistence and bioavailability, thereby influencing turfgrass tolerance.

Preemergence herbicides are used for weed control in turfgrass systems. Indaziflam is a preemergence herbicide used in warm‐season turfgrasses for grassy and broadleaf species. Field research was completed to evaluate the effect of various preemergence herbicide application regimens on established hybrid bermudagrass [Cynodon dactylon (L.) Pers. × Cynodon transvaalensis Burtt‐Davy ‘Tifway’] cover and root mass on sand soils. Evaluated regimens included indaziflam followed by (fb) indaziflam (14 g a.i. ha−1 fb 14 g a.i. ha−1), indaziflam fb indaziflam (21 g a.i. ha−1 fb 21 g a.i. ha−1), indaziflam fb oxadiazon (21 g a.i. ha−1 fb 3285 g a.i. ha−1), indaziflam fb prodiamine (21 g a.i. ha−1 fb 821 g a.i. ha−1), prodiamine fb oxadiazon (821 g a.i. ha−1 fb 3285 g a.i. ha−1) and prodiamine fb prodiamine (821 g a.i. ha−1 fb 821 g a.i. ha−1) applied fall fb late winter in each of two yr. Indaziflam treatment regimens did not adversely affect hybrid bermudagrass cover compared with the nontreated check at any evaluation time. Indaziflam fb prodiamine was the only treatment that consistently reduced hybrid bermudagrass root mass compared with the nontreated check. Results of this research indicates low rates (≤21 g ha−1) of indaziflam may be used without adversely affecting hybrid bermudagrass cover or rooting, providing practitioners with an alternative mode of action compared with conventional mitotic and protoporphyrinogen oxidase inhibitors; however, additional research is needed to quantify effects over multiple application seasons and years.

Topramezone is a broad‐spectrum selective herbicide currently labeled for postemergence weed control in turfgrass. Little is known about its residual effects on sprigged establishment of hybrid bermudagrass (Cynodon dactylon L. Pers. × C. transvaalensis Burtt‐Davy). Research was conducted at the Mississippi State University Turfgrass Research Center on the R.R. Foil Plant Science Farm near Starkville, MS, during summer 2014 and 2015 to evaluate the effects of topramezone (0.049 kg a.i. ha−1) and prodiamine (0.84 kg ha−1) on hybrid bermudagrass (52 m3 ha−1) sprigged directly after herbicide application as well as 1, 2, and 4 wk after application (WAA). Percentage visual estimates of hybrid bermudagrass cover and normalized difference vegetative index (NDVI) were assessed 12 WAA. Visual cover was compared with nontreated plots sprigged on the same date. Regression estimates were calculated for visual hybrid bermudagrass cover and NDVI to demonstrate the effects of sprigging date after herbicide application. Topramezone did not reduce visual estimates of cover or NDVI when hybrid bermudagrass was sprigged directly after herbicide application in either year. Prodiamine did not reduce hybrid bermudagrass cover compared with the nontreated during 2014 but reduced hybrid bermudagrass cover at all sprigging dates except 1 WAA during 2015. Results suggest that topramezone is relatively safe to use for site preparation before sprigging hybrid bermudagrass at any time interval. Future research may assess topramezone in combination with other pre‐emergence herbicides for effective and economically viable alternatives to existing selective and nonselective herbicide applications within sprigged hybrid bermudagrass establishment.

Buffalograss [Buchloë dactyloides (Nutt.) Engelm. syn. Bouteloua dactyloides (Nutt.) Columbus] is often reported as being intolerant of shade, traffic, and sandy soils. Historically, these observations were made on early turf‐type cultivars or common types and may not reflect performance of modern cultivars and germplasm selections. As an example, the 1991, 1996, and 2002 buffalograss National Turfgrass Evaluation Program (NTEP) trials had evaluation sites consisting of sandy loam to sandy clay loam. One of the four sandy loam sites in the 1991 trial, and five of nine sandy loam–sandy clay loam sites in the 1996 and 2002 tests had buffalograss entries rating 6.0 or greater. We have since successfully established buffalograss on sandy sites with management changes typical of grasses considered adapted to sandy sites. In addition, multiyear shade and traffic studies were conducted at the University of Nebraska–Lincoln turfgrass research farm. A Brinkman traffic simulator was used to apply weekly traffic to 104 buffalograss genotypes from mid‐June through October in 2013 and 2014. Following 2 yr of moderate traffic, 70 of the genotypes were minimally affected by the traffic treatment. Shade tolerance studies were started in 2009 and 2013. Three buffalograss genotypes rated in the top 6% of 54 genotypes evaluated when grown under 60% shade cloth in the 2009 study. In 2013, four buffalograss entries grown under 60% shade cloth rated in the top 12% of 34 evaluated genotypes. A comparison of relative performance of 16 genotypes in common among the 2009 and 2013 shade studies highlight significant variability in performance under different environmental conditions and the need for revisiting historical recommendations.

An annual bluegrass (Poa annua L.) phenotype suspected to be resistant to photosystem II (PSII)‐inhibiting herbicides was identified in a zoysiagrass [Zoysia matrella (L.) Merr., cv. ‘Royal’] sod production field during 2013. Research was conducted during 2013 to 2015 to confirm if this phenotype (R) was resistant to PSII‐inhibiting herbicides and evaluate alternative herbicide options for effective preemergence control. In the glasshouse, treatment with the PSII‐inhibiting herbicide simazine at the maximum labeled rate for use in sod production (2240 g ha−1) only controlled this R phenotype 33%, and increasing the application rate to 9000 g ha−1 did not improve control. Comparatively, simazine controlled a known susceptible phenotype (S) 100% at both rates. DNA sequencing identified a genetic mutation in R annual bluegrass that resulted in a serine‐to‐glycine substitution at amino acid residue 264 on the D1 protein targeted by simazine. In the field, applications of simazine at rates of 140 to 9000 g ha−1 controlled R annual bluegrass ≤3% by 212 d after treatment. Applications of indaziflam (35, 52.5, and 70 g ha−1), oxadiazon (3350 g ha−1), prodiamine + sulfentrazone (844 + 416 g ha−1), and pendimethalin + dimethenamid‐P (2240 + 1686 g ha−1) controlled this R phenotype 98 to 100% and reduced plant counts similarly. Our findings confirm the presence of annual bluegrass in a zoysiagrass sod production field that is resistant to PSII‐inhibiting herbicides via target site mutation of the D1 protein. However, rotation to preemergence herbicides with alternative mechanisms of action to simazine can effectively control this phenotype. This marks the first reported case of herbicide‐resistant annual bluegrass in a sod production system. Management of this phenotype is critically important considering that harvesting and shipment of sod could potentially disseminate plants with target site mutations conferring resistance to PSII‐inhibiting herbicides over a wide geographical area.

Cultivation practices on athletic fields reduce compaction caused by continuous traffic from sporting events; however, this cultural practice can reduce turf coverage and quality. The objective of this research was to determine the effects of combining dry‐injection (DI) cultivation with a traditional hollow‐tine (HT) cultivation program on soil physical properties. Research was conducted from 1 May to 31 Aug. 2014 and 2015 on a native soil ‘Tifway’ bermudagrass [Cynodon dactylon (L.) Pers. × C. transvaalensis Burtt Davy] playing surface at the Mississippi State University practice football field in Starkville, MS. Treatments included a combination of HT cultivation, DI cultivation at three frequencies and two depths (12.6 and 24.4 cm), and HT combined with three DI cultivation programs. Hollow‐tine treatments were applied once each year (July). The DI treatments were applied at various frequencies during June, July, and August over the 2‐yr study with a DryJect Maximus. Hollow‐tine treatments significantly reduced surface firmness compared with five DI 12.6‐cm‐depth applications over 2 yr. Incorporating HT into two DI applications to the 24.4‐cm depth reduced surface firmness by 12% compared with two DI applications to the 12.6‐cm depth. No differences in thatch‐mat depth, organic matter concentration, chlorophyll index, normalized difference vegetative index, and turfgrass recovery were observed. Results indicate that DI cultivation used once per year over a 2‐yr period at the 24.4‐cm depth combined with HT on a native soil athletic field is an effective option to reduce soil compaction.

For intensively managed golf greens, organic fertilizers are recommended as an alternative to synthetic fertilizer to reduce nutrient contamination. Dissolved organic C (DOC) strongly enhances solute mobility. Golf greens were established as ‘Penncross’ creeping bentgrass (Agrostis stolonifera L.) sod to examine two commercial organic fertilizers, Milorganite and Nature Safe, compared with synthetic fertilizer and their influence on DOC and phosphate (PO43−) leachate concentrations. Greens were constructed according to the recommendations of the US Golf Association (USGA). Leachates from fertilizer were analyzed for DOC and PO43−. Fertilizers were applied as three applications at 50 kg N ha−1 in July, September, and October of 2006. Total P applied was 24.2, 21.5, and 11.2 kg ha−1 for Nature Safe, Milorganite, and synthetic fertilizer, respectively. Dissolved organic C from Milorganite in the fertilizer was 2.4 vs. 0.9% for Nature Safe, with the DOC extract from Milorganite containing 2.7‐fold greater C content than Nature Safe. Greater DOC from Milorganite more strongly influenced PO43− transport than Nature Safe DOC. Concentrations of PO43− were correlated with DOC in leachate (r = 0.68, P ≤ 0.001). Milorganite promoted 15 to 18% greater PO43− in leachate than synthetic fertilizer and Nature Safe, with Milorganite PO43− as high as 2.49 mg L−1. Greater PO43− in leachate, with Milorganite having 13% lower total P than Nature Safe, can be attributed to Milorganite's 2.7‐fold greater DOC content. The results suggest that DOC from organic fertilizer and their chemical properties may increase PO43− leaching especially on soils with low P sorption capacities.
