Weed Control and Cultivar Tolerance to Saflufenacil in Soybean (Glycine max)

Weed Control and Cultivar Tolerance to Saflufenacil in Soybean (Glycine max) Robert Thomas Miller University of Guelph, 2012 Advisors: Peter H. Sikkema Darren E. Robinson Studies were conducted in 2009 and 2010 under field and growth room conditions to determine a) cultivar tolerance of soybean to preemergence (PRE) applications of saflufenacil and b) the biologically effective rate of saflufenacil/dimethenamid-p for control of annual weeds applied PRE alone and prior to an in-crop application of glyphosate. Environmental conditions following application influenced the amount of soybean injury caused by saflufenacil, as well as the rate of saflufenacil/dimethenamid-p required for the control of annual weeds. Increased soybean injury from saflufenacil was observed when soybean emergence was delayed due to cool, wet conditions following planting. Injury decreased with time; however, sensitive soybean cultivars were unable to fully recover from early season injury under adverse environmental conditions. OAC Hanover was the most sensitive cultivar in both field and hydroponic testing. With adequate moisture and above average temperatures in 2010, between 224 and 374 g a.i. ha of saflufenacil/dimethenamid-p was required for 80% control of common ragweed, common lambsquarters, and green foxtail 4 weeks after treatment (WAT). In contrast, with below average temperatures and excessive moisture in 2009, between 528 and 613 g a.i. ha of saflufenacil/dimethenamid-p was necessary for the same level of weed control. Pigweed species were least affected by environmental conditions after application with only 245 g a.i. ha required for 80% control 4 WAT in both years. Excellent full season control of all weed species was achieved with saflufenacil/dimethenamid-p applied PRE followed by glyphosate postemergence (POST). However, there was no difference in yield when saflufenacil/dimethenamid-p was followed by glyphosate POST compared to a single glyphosate POST application.
Functional analysis of the accumulation associated protein (Aap) of Staphylococcus epidermidis

S. epidermidis is one of the primary opportunistic pathogens associated withindwelling medical devices such as intravenous catheters and artificial heartvalves and joints. S. epidermidis is also a permanent commensal resident onhuman skin and mucus membranes providing a large potential reservoir for thecontamination of medical implants. Persistent colonisation of implants occurs viabiofilm formation and infected implants must usually be replaced. The surfaceboundprotein, accumulation associated protein (Aap), is one of the main biofilmpromoting surface molecules on S. epidermidis. Aap is a LPXTG protein with arepetitive B-region, thought to promote biofilm formation as well as providing astalk structure to project the A-domain away from the cell surface. Aap isexpressed in lateral tufts of fibrils on the surface of a sub-population of strainNCTC 11047 and, here, similar sub-populations are shown to be present inother S. epidermidis strains. In order to determine the function of specificdomains of Aap in adhesion and biofilm formation Aap constructs with andwithout the A-domain and with varying numbers of B-repeats were expressed onthe surface of Lactococcus lactis MG1363 and Staphylococcus aureus. Theexpression of Aap with the A-domain on the surface of L. lactis increasedcorneocyte adhesion 20-fold compared to L. lactis carrying Aap without an Adomain. Several S. epidermidis isolates also used the A-domain of Aap toadhere to corneocytes, emphasizing the role of Aap in skin adhesion. Inaddition, Aap promoted adhesion to polystyrene although only the A-domainadditionally promoted adhesion to tissue culture treated polystyrene.Furthermore, biofilms were cultivated under flow conditions and analyzed byconfocal microscopy. Aap, with the A-domain on the surface of both L. lactis andS. aureus, enhanced microcolony formation suggesting a potential role for the Adomainin the early stage of biofilm formation. The A-domain of Aap is thereforemultifunctional because, in addition to mediating adhesion to corneocytes it canpromote initial attachment to polystyrene and functions in the early accumulationstage of biofilm formation.
Large‐scale pattern of biomass partitioning across China's grasslands

Aim To investigate large-scale patterns of above-ground and below-ground biomass partitioning in grassland ecosystems and to test the isometric theory at the community level. Location Northern China, in diverse grassland types spanning temperate grasslands in arid and semi-arid regions to alpine grasslands on the Tibetan Plateau. Methods We investigated above-ground and below-ground biomass in China's grasslands by conducting five consecutive sampling campaigns across the northern part of the country during 2001-05. We then documented the root : shoot ratio (R/S) and its relationship with climatic factors for China's grasslands. We further explored relationships between above-ground and below-ground biomass across different grassland types. Results Our results indicated that the overall R/S of China's grasslands was larger than the global average (6.3 vs. 3.7). The R/S for China's grasslands did not show any significant trend with either mean annual temperature or mean annual precipitation. Above-ground biomass was nearly proportional to below-ground biomass with a scaling exponent (the slope of log-log linear relationship between above-ground and below-ground biomass) of 1.02 across various grassland types. The slope did not differ significantly between temperate and alpine grasslands or between steppe and meadow. Main conclusions Our findings support the isometric theory of above-ground and below-ground biomass partitioning, and suggest that above-ground biomass scales isometrically with below-ground biomass at the community level.
Histoire évolutive des remaniements chromosomiques en liaison avec la mobilisation d'éléments transposables chez les téléostéens antarctiques Nototheniidae : la radiation adaptative du groupe " Trematomus "

L’alternance de periodes glaciaires et interglaciaires durant les 20 derniers Ma a mene a des changements environnementaux repetes au niveau du plateau continental antarctique. C’est dans ce contexte que les teleosteens de la famille des Nototheniidae se sont adaptes et diversifies a travers plusieurs vagues de radiations (dont les Trematominae), dominant l’Ichtyofaune australe. Parmi les Nototheniidae, le groupe « Trematomus » (genres Cryothenia, Pagothenia, Trematomus et Indonotothenia) est celui ou l’on observe la plus grande diversite chromosomique, avec des nombres diploides de chromosomes allant de 24 a 58, impliquant de nombreux rearrangements ayant accompagne les speciations. Nous avons cherche a caracteriser ces remaniements chromosomiques. Avec un caryotype ancestral infere de 2n = 48, une conservation des unites chromosomiques entre especes, et une constance des tailles de genome, l’hypothese de rearrangements structuraux sans polyploidisation prealable est la plus probable. Afin de reconstruire l’histoire evolutive de ces evenements, nous avons recherche les homologies chromosomiques interspecifiques. Ceci nous a permis de reconstituer les remaniements (majoritairement des fusions) que nous avons repositionnes sur la phylogenie resolue des « Trematomus ». Contrairement a ce qui a ete publie pour le genre Notothenia, nos resultats suggerent des acquisitions multiples et independantes. Les elements transposables (ETs) peuvent etre impliques dans les remaniements chromosomiques par le biais de recombinaisons ectopiques. Ils participent alors a la diversification des lignees au cours de l’evolution. En raison de leur regulation epigenetique, leur mobilisation massive peut etre induite en cas de variations environnementales importantes. Nous nous sommes interesses a trois super-familles d’ETs (DIRS, Gypsy and Copia) dans ces genomes. Les DIRS1 ont montre des patrons d’insertions en points chauds dans les regions centromeriques et pericentromeriques. Etant donne leur mode de transposition decrit et leur propension a s’inserer dans des copies preexistantes, nous proposons un role des elements DIRS1 comme facilitateurs des fusions observees lors de la diversification des « Trematomus ».
The impact of video game intervention on reducing stress and enhancing language achievement and communication skills

This study investigated whether video game intervention can play a role in reducing stress, and in improving English language proficiency and communication skills of English as Foreign Language (EFL) learners in Iran. Elementary EFL students (n = 100) fromtwo classes at a private language institute voluntarily participated in this study. The participants were randomly divided into two groups. The experimental group had video games incorporated into their learning experiences for eightweeks, while the control group’s learning experiences remained unchanged. The participants completed measures of perceived stress, communication skills, and an English language proficiency test at pre-test and post-test stages. Additionally, five students were randomly selected from each group and invited for semi-structured interviews. Analysis indicatedthat perceived stress decreased significantly in the experimental group while the level of stress did not change in the control group. Additionally, the communication skills and English language proficiency of students in the experimental group also increased significantly, but remained unchanged in the control group. These findings suggest that video game intervention holds potential as a tool for decreasing stress in Iranian EFL students and for enhancing their communication skillsin English language classrooms. Additionally, video game interventions may enrich teacher-student relationships.
Factors Affecting Users' Purchase Intention and Attitudes towards Mobile Advertising

The growing number of mobile users encourages companies to take advantage of these opportunities to improve their marketing strategy. One of the marketing strategies that can be done through mobile devices is mobile advertising. However, the problem is that many users still consider mobile advertising as spam and many companies do not know how to start mobile advertising. While to start mobile advertising, must first understand the attitude of mobile users themselves. Therefore, this study aims to analyze the factors that can affecting Tokopedia application user's attitude to mobile advertising seen from affective and cognitive side. Additionally, this study aims to analyze the impact of mobile advertising on purchase intention of users to purchase products or services offered through mobile advertising. This research uses quantitative approach which is done by collecting respond from 565 Tokopedia application user's. The data is then analyzed using CB-SEM method using AMOS 21. Based on the results of analysis, the writers found that perceived ease of use, perceived usefulness, positive emotions, and negative emotions affect the user's attitude towards mobile advertising. Next, attitude also has an effect on user's purchase intention on advertised products or services.
Bilingual first language acquisition at the interface between syntax and pragmatics

The present article provides an overview of some recent research in bilingual first language acquisition with special reference to Romance languages. It addresses two language contact phenomena, language mixing at the lexical level and crosslinguistic influence at the syntactic level. For both contact phenomena, there is evidence that they are unrelated to language dominance (as measured in terms of MLU). Language mixing is negatively correlated with the number of utterances per minute, a measure for language fluency. Cross-linguistic influence at the syntactic level is due to computational complexity which is caused for example by the invasive interplay of pragmatics and syntax. This kind of interplay will be discussed on the basis of the presence or absence of the null-subject property, comparing Italian and German, and by studying the presence or absence of object clitics, comparing French and German. Since cross-linguistic influence affects bilingual individuals to different degrees (sometimes referred to as individual variation), we discuss the assumption that the degree to which the influence manifests itself differs as a function of fluency (measured in words produced per minute). The more fluent the child is in the language with the computationally complex analysis, the less the effect of cross-linguistic influence. In sum, the language which exhibits influence is determined by computational complexity as defined, for example, by the invasive interplay between pragmatics and syntax. The degree of manifestation of the influence depends on fluency in the computationally complex language.
Developmental anomalies: Mutational consequence of mouse zygote exposure

One of the objectives of mutagenesis research in mice is to enrich our knowledge of basic mammalian biology. The practical goal is to apply this knowledge to the problems of human health. The research described here exemplifies this philosophy. The observation that certain mutagens induced high incidences of fetal anomalies and death following exposure during the zygote stage is a new phenomenon in mutagenesis and experimental embryopathy. The mechanism for the induction of zygote-derived anomalies appears to be genetic, but it is not of the conventional type. These zygote-derived anomalies resemble the large class of stillbirths and sporadic defects in humans that are of unknown etiology. The zygote research in mice presents an opportunity for studying the molecular and cellular pathogenesis of this class of defects. 12 refs., 1 fig., 3 tabs.
The Biographical and Human Resource Management Predictors of Union Membership Engagement of Low- and Middle-Income Workers

In this study, the researcher investigated the biographical and human resource management (HRM) predictors of union membership. The literature reviewed revealed that there is little research on this topic in the South African context. The literature reviewed also showed that males, permanent employees, employees who are less committed, who have a level of quality of work-life (QWL) and engagement, and those who are satisfied are more likely to be unionized. A cross-sectional survey design was used to address the research questions. One thousand questionnaires were distributed and 874 were completed by the respondents at Marabastad Mall in the City of Tshwane Metropolitan Municipality (CTMM) in South Africa. The study results showed that employment status was the highest predictor ( -1.782, p<0.05) of union membership, and gender and job satisfaction were not predictors of union members. This study had managerial implications, in the sense that when hiring employees on a part-time basis, having employees who are committed and offering employees QWL (i.e. excellent fringe benefits) will impact negatively on union membership. In terms of policymakers, the study revealed that developing remuneration policies that are pro-employee (i.e. offering excellent working conditions and fringe benefits) would make them satisfied, possibly be productive, and they would engage less in counterproductive industrial actions like strikes, which in South Africa are the amongst highest in the world.
Functional traits of alien plants across contrasting climatic and land‐use regimes: do aliens join the locals or try harder than them?

1 Two main views have been put forward to explain whether coexisting alien and resident plant species should show converging or diverging functional attributes. According to the ‘try‐harder’ hypothesis, successful aliens should differ from resident species with traits that allow them to deal better with the local conditions than resident species. On the other hand, the ‘join‐the‐locals’ hypothesis stresses the importance of filtering by environmental factors and predicts strong functional trait similarities between alien and native species, especially among the dominants.
Managing Impulsive Purchases in Multi-Channel Online Retailing: Product Categories and Organizational Choices

Multiple online channels allow a retailer to cover a wider range of situational purchase settings but also expose it to a more complex spectrum of consumer purchase behavior. Compared with the conventional desktop computer-based Web channel, the mobile-based application channel enables retailers to understand consumers better and, also, makes them more vulnerable to impulse purchases. The unique features of consumer experience and purchase behavior in each online channel raise the question of whether these channels should be managed jointly or separately. This study seeks to identify retail settings that favor a particular organizational choice. The extant literature on multi-channel retail has paid scant attention to differences between these primary online channels. Our study helps to fill this gap, and it aims to equip retailers with a simple tool for comparing the organization's choices with regard to managing sales across the two channels. We build a parsimonious model that captures key aspects of consumers' impulsive purchase behavior across various product types and two different online channels. In this model, the consumer's utility from purchasing a product via a particular channel consists of two correlated components: a channel-independent "base'' component and a channel-specific "impulsive'' component. We use this model to examine retailer performance when pricing is delegated to managers under separate-channel and joint-channel management schemes. We find that products which induce impulsive purchase behavior strongly correlated with the base product valuation, such as high-value hedonic products, favor the joint-channel setup. In contrast, products with strong negative correlation between the base and impulsive valuation components, such as high-end durables, do better under separate-channel management. Online retailers should carefully curate their delegation strategies to manage the interplay between channels' natural differences and the product characteristics that shape how consumers' impulsive purchase behavior is related to their base valuations.
A comparative study on the chemical and physical attributes of wild farmed Nile tilapia (Oreochromis niloticus).

The research was directed towards the study of the fish species Orcochromis niloticus (Trewavas), formerly Tilapia nilotica (Linnaeus) in order to comparing the chemical composition and fish body weight characteristics of its farmed with their natural counterpart (collected from Nile River). Forty nine assorted fish species of each group (Tilapia noliticus) were randomly collected fresh from Sudan University Fish Farms and Nile River. For two groups the filleting yield (head, skin, viscera, fins and skeleton and fillet were taken) and chemical analysis were performed. The sequence percentage variation of fish body weight components in each fish was varied among studied species. Thus the order tend to decrease from fillet, head, fins and skeleton, viscera and skin in farmed fish and from fillet, head, fins and skeleton, skin and viscera in wild fish. Concerning the chemical analysis of major body constituents of studied fish whose main elements moisture, dry matter, ash, protein, fat and NFE were determined. Protein and fat content level was found to be significantly different (P 0.05) in the farmed and wild fish species.

The Proterozoic Biosphere: Atlas of Representative Proterozoic Microfossils

Introduction On the following plates are illustrated microfossils from 48 geologic units (representing about 10% of the units listed in Table 22.3). Although coverage is by no means exhaustive, the fossils illustrated are representative of the diversity and level of organization exhibited by particularly well-preserved Proterozoic assemblages. In selecting the fossils illustrated, emphasis has been placed on inclusion of holotype specimens, particularly holotypes of taxa described from the Soviet Union, relatively few of which have been previously illustrated in the non-Russian language literature (and none of which has been previously illustrated using interference contrast optics). As summarized below, emphasis has also been placed on illustration of assemblages of Middle and Late Proterozoic age; this atlas therefore complements, but does not duplicate, illustrations of Early Proterozoic communities included in Hofmann and Schopf (1983). The atlas contains more than 300 new illustrations, including photomicrographs of specimens not previously figured from the Dismal Lakes Group, River Wakefield Subgroup, Skillogalee Dolomite, the Gunflint Iron Formation, and the Gaoyuzhuang, Galeros, Kwagunt, and Myrtle Springs Formations. Acknowledgments Soviet type specimens were provided for study by E. Aseeva, T. N. Hermann, T. Jankauskas, N. Mikhailova, V. Sergeev, and A. Weiss; photomicrography of these specimens was carried out by C. V. Mendelson, J. W. Schopf, and G. Vidal; this work, conducted at the Palaeontological Institute in Moscow, was facilitated through the courtesy of M. A. Fedonkin and B. S. Sokolov. Studies of new material from the Gaoyuzhuang Formation were carried out in collaboration with R. Mikawa (University of Chicago); studies of new specimens from the River Wakefield Subgroup and the Skillogalee Dolomite were carried out by or in collaboration with T. R. Fairchild (Universidade de Sao Paulo, Brazil).
