Effect of foliar and substrate fertilization on lady palm seedling growth and development

Lady palm, [Rhapis excelsa (Thunberg) Henry ex. Rehder] is one of the most cultivated ornamental palms in the world, for use as a vase plant or in shaded landscapes. Because limited information exists on lady palm response to fertilizers, the objective of this study was to evaluate the effect of different types of fertilization and substrates on lady palm seedling growth and development. Three year old lady palms were planted in 8-L pots, filled with a mix of soil, manure, and sand 1:1:1 (v:v:v), placed under a 50% shade, and irrigated with microspray. Treatments were substrate fertilization with 500 g P(2)O(5) and 100 g K(2)O per m(3); fertilization with 1.8 kg of P(2)O(5) (simple superphosphate) per m3; 50 g of nitrogen (N), P(2)O(5), and K(2)O of a granulated fertilizer (10:10:10) per m(3), control (without fertilization), and a foliar fertilization in addition to these treatments using the commercial product Biofert (8:9:9). Treatments were replicated four times in a randomized block design. Each treatment plot consisted of four plants. Data were collected at 140, 170, 200, 230, 260, and 290 days after transplanting (DAT) for plant heights, stem diameter at substrate level, number of leaves, shoots, and canopy, roots fresh and dry matter samples were harvest at 290 days. Foliar fertilization resulted in significantly greater plant height in a 140, 120, 200, and 230 DAT and plant diameter on the 140, 260, and 290 DAT. There was interaction among factors for number of leaves with fertilization based on P(2)O(5) and K(2)O when leaf fertilizer was added that resulted in a greater number of leaves.

Prompt and non-prompt J/ψ production in pp collisions at √s =7 TeV

The production of J/ψ mesons is studied in pp collisions at √s = 7 TeV with the CMS experiment at the LHC. The measurement is based on a dimuon sample corresponding to an integrated luminosity of 314 nb-1. The J/ψ differential cross section is determined, as a function of the J/ψ transverse momentum, in three rapidity ranges. A fit to the decay length distribution is used to separate the prompt from the non-prompt (b hadron to J/ψ) component. Integrated over J/ψ transverse momentum from 6.5 to 30 GeV/c and over rapidity in the range {pipe}y{pipe} < 2.4, the measured cross sections, times the dimuon decay branching fraction, are 70.9 ± 2.1(stat.) ± 3.0(syst.) ± 7.8(luminosity) nb for prompt J/ψ mesons assuming unpolarized production and 26.0 ± 1.4(stat.) ± 1.6(syst.) ± 2.9(luminosity) nb for J/ψ mesons from b-hadron decays. © CERN for the benefit of the CMS collaboration 2011.

Stuart Hall, cultural studies e a nostalgia da dominação hegemônica

Stuart Hall é um dos poucos autores contemporâneos que ainda se apóia no conceito de ideologia. Ela interfere na língua falada definindo limites, regulando a forma discursiva com a intenção de estabilizá-la e congelá-la. Ela domina o bloco histórico e a estratégia seria a de unir as camadas populares, a partir de dentro, para que estas possam fortificar-se e combatê-la. Mas todo esse esquema tem sabor nostálgico, como se houvesse uma manobra dos poderosos e os dominados não se identificassem com os signos de poder e prestígio. Como no caso da “leitura crítica”, não seria o caso de modernizar Stuart Hall?

L'adulterio come strumento sociale: confronto tra Anna Karenina e Lady Chatterley

Lo scopo di questo lavoro è confrontare due opere, Anna Karenina di Lev Tolstoj e L’amante di Lady Chatterley di David Herbert Lawrence e dimostrare che essi non hanno in comune solo il tema dell’adulterio, ma anche e soprattutto l’averlo inteso come strumento di ribellione sociale. In Tolstoj troviamo l’adulterio censurato nel corso della narrazione, poiché esso viene condannato sia dalla società che dall’autore stesso, che aveva come intento dare una lezione morale. Lawrence invece esalta e descrive l’adulterio, poiché nel suo caso diventa lo strumento di scoperta dell’amore vero e di ritorno al primitivismo a dispetto della civiltà industrializzata. Quindi, pur appartenendo a due epoche diverse e a due società con differenti visioni circa matrimonio e famiglia, le due eroine sono similari per il coraggio che dimostrano nell’andare contro le rispettive società.

The Lady Footballers and the British Press, 1895

Nettie Honeyball and Florence Dixie founded the British Ladies Football Club (BLFC) in 1894 with the aim to provide football-playing opportunities for girls and young women, but also as a means of making money. Theirs, in effect, was an attempt to create a professional football league for women. Public interest in 'the lady footballers' was enormous, at least in its early stages, and generated considerable attention from the press. Overall, press coverage of the BLFC was negative (football is a man's sport; football is a working-class sport; women are physically incapable of playing the game; women shouldn't appear publicly in bifurcated garments, etc.), with only a few notable exceptions. Did the stance adopted depend on the political leaning of the newspaper? Or were the reporters simply reflecting the social and economic realities of their time, struggling to 'explain' a marginal group - women athletes, or more specifically, middle-class women football players - engaging in a working-class male game? This article examines the press coverage of the BLFC. The double standard evident in the newspaper coverage was, on the surface, as one might expect: if a woman played well, she was a freak, possibly a man in disguise; if she didn't play well, it proved that women shouldn't play football. But on closer examination, the double standard was actually rather nuanced: if she played well and looked the part of a woman, she could be subject to praise; yet if she played well and didn't conform to the standard of feminine beauty, she faced ridicule, and her gender called into question.
