(Anti-)chiral Superfield Approach to Nilpotent Symmetries: Self-Dual Chiral Bosonic Theory

We exploit the beauty and strength of the symmetry invariant restrictions on the (anti-)chiral superfields to derive the Becchi-Rouet-Stora-Tyutin (BRST), anti-BRST and (anti-)co-BRST symmetry transformations in the case of a two (1+1)-dimensional (2D) self-dual chiral bosonic field theory within the framework of augmented (anti-)chiral superfield formalism. Our 2D ordinary theory is generalized onto a (2, 2)-dimensional supermanifold which is parameterized by the superspace variable Z^M = (x^\mu, \theta, \bar\theta) where x^\mu (with \mu = 0, 1) are the ordinary 2D bosonic coordinates and (\theta,\, \bar\theta) are a pair of Grassmannian variables with their standard relationships: \theta^2 = {\bar\theta}^2 =0, \theta\,\bar\theta + \bar\theta\theta = 0. We impose the (anti-)BRST and (anti-)co-BRST invariant restrictions on the (anti-)chiral superfields (defined on the (anti-)chiral (2, 1)-dimensional super-submanifolds of the above general (2, 2)-dimensional supermanifold) to derive the above nilpotent symmetries. We do not exploit the mathematical strength of the (dual-)horizontality conditions anywhere in our present investigation. We also discuss the properties of nilpotency, absolute anticommutativity and (anti-)BRST and (anti-)co-BRST symmetry invariance of the Lagrangian density within the framework of our augmented (anti-)chiral superfield formalism. Our observation of the absolute anticommutativity property is a completely novel result in view of the fact that we have considered only the (anti-)chiral superfields in our present endeavor.Comment: LaTeX file, 20 pages, journal reference is give

The Wear Project

When we meet a character in a performance, the implicit understanding is that they have existed until the point where we join their journey and will continue existing after we leave them. Their clothing tells a story to the audience before any words are spoken and before any action takes place. As a Costume Designer and Lecturer, my awareness of costuming as an anthropological practice has led me to explore these principles using myself as the subject of scrutiny. For one year I am logging every clothing combination I go through along with memories, prices, locations and dates etc. in order to explore the clothing decisions I make and the stories, embedded in my clothes, that I am surrounded by every day. What does my wardrobe mean to me inwardly and reveal outwardly to others? How does this 'me-search' extend my artistic practice? The Wear Project will be a visual archive, a teaching tool, and a foundation for further academic research/writing through the questions it raises about design, visual storytelling, memory, dress and audience: a personal interrogation generating a critical framework for understanding the dramaturgical significance of costume. I welcome any interest, suggestions, questions, provocations, conversations or counter- projects that could lead my research, costume design or performance related teaching in general into unexplored areas. The Wear Project is available for anybody to view or use on flickr at http://bit.ly/1kAYv74

Pedagogies applied to develop student self-awareness and written self-evaluations: a costume case study

In 2013–14 a change in assessment criteria percentage weightings on the BA Stage Management and Technical Theatre course at East 15 Acting School was implemented – a course taught mainly through authentic learning processes. This change, coupled with the increase in emphasis on reflective processes in higher education in general, highlighted that students not only on this course but also more widely need to be able to articulate their learning more rigorously than before through more comprehensively written self-evaluations. Through a discussion of critical thinking and reflection and instinctively applying Art and Design pedagogies to teaching on what is traditionally considered to be a vocational course, this article charts an experimental case study following students on the Costume Pathway, hoping to improve their ability in this area. The aim was to develop the self-awareness and analytical and reflective thinking involved in evaluating personal working practices to a high standard in order to improve the written communication thereof. Therefore, this article is also a reflection on how a thorough understanding from educators of what self-evaluation demands of students can enrich student learning experiences and develop transferable skills to produce industry-ready and life-ready graduates

Carryover effects of residual herbicides at three sites in N.E. Saskatchewan

Non-Peer ReviewedThe residual effects of three rates of picloram, chlorsulfuron, metsulfuron, metribuzin, and cyanazine, applied to a Vierdale loam (Heath Park), Helfort silty clay loam and Etomami clay (Somme) in 1985, were investigated on eight rotational crops. Picloram applied to cereals at the recommended rate of 0.024 kg/ha continued to suppress yields of lentils and field peas two years after application. Alfalfa, red clover and sweetclover were not affected, whereas canola yield increased due to the residual weed control provided by the herbicide. Chlorsulfuron residues adversely affected lentils, canola, red clover and sweetclover even at the lowest rate of 0.01 kg/ha but peas were not affected. Hetsulfuron residues from the 0.006 kg/ha rate injured lentils, red clover and sweetclover. The recommended rates of metribuzin (0.41 kg/ha) and cyanazine (1.44 kg/ha) for TT-canola did not have any carryover effects, whereas the 2× rates injured lentils, peas, and Tobin canola two years after application. Crested wheatgrass and smooth bromegrass were not affected by any of the herbicides tested even 1 year after application. In general, the risk of injury to rotational crops was greatest at Meath Park (pH = 7.8, OM = 5.6 %) and least at Melfort (pH = 6.2, OM = 12 %)

Pertumbuhan Tinggi Tanaman Sambiloto (Andrographis Paniculata. Ness) Hasil Pemberian Pupuk Dan Intensitas Cahaya Matahari Yang Berbeda

This study aimed to evaluate the effect of fertilization and different light intensities on growth of plant height of bitter plant (Andrographis paniculata Ness). The study was conducted using Completely Randomized Design (CRD) with 3 x 3 factorial pattern. The main factor was fertilization treatment consisted of three levels: NPK (Urea 1.2 grams per plant, TSP 2.4 g per plant and KCl 0.6 g per plant), animal manure (1.2 kg per plant) and without fertilization. The second factor was the different light intensities consisted of three levels: full light intensity, half-shade and full shade. Each treatment combination was repeated 3 times. Growth of plant height was observed 1 and 2 months after application of fertilizer and light intensity. Data were analyzed using the Analysis of Variance (Anova).The research results showed that bitter plant height differed at fertilization levels and different light intensities. NPK fertilization combined with 40 % light intensity (P2N1) gave the highest plant height

Spatial structures and directionalities in Monsoonal precipitation over South Asia

Precipitation during the monsoon season over the Indian subcontinent occurs in form of enormously complex spatiotemporal patterns due to the underlying dynamics of atmospheric circulation and varying topography. Employing methods from nonlinear time series analysis, we study spatial structures of the rainfall field during the summer monsoon and identify principle regions where the dynamics of monsoonal rainfall is more coherent or homogenous. Moreover, we estimate the time delay patterns of rain events. Here we present an analysis of two separate high resolution gridded data sets of daily rainfall covering the Indian subcontinent. Using the method of event synchronization (ES), we estimate regions where heavy rain events during monsoon happen in some lag synchronised form. Further using the delay behaviour of rainfall events, we estimate the directionalities related to the progress of such type of rainfall events. The Active (break) phase of a monsoon is characterised by an increase(decrease) of rainfall over certain regions of the Indian subcontinent. We show that our method is able to identify regions of such coherent rainfall activity
