Accounts of the governance of prostitution have typically argued that prostitutes are, in one way or another, stigmatised social outcasts. There is a persistent claim that power has operated to dislocate or banish the prostitute from the community in order to silence, isolate, hide, restrict, or punish. I argue that another position may be tenable; that is, power has operated to locate prostitution within the social. Power does not operate to 'desocialise' prostitution, but has in recent times operated increasingly to normalise it. Power does not demarcate prostitutes from the social according to some binary mechanics of difference, but works instead according to a principle of differentiation which seeks to connect, include, circulate and enable specific prostitute populations within the social. In this paper I examine how prostitution has been singled out for public attention as a sociopolitical problem and governed accordingly. The concept of governmentality is used to think through such issues, providing, as it does, a non-totalising and non-reductionist account of rule. It is argued that a combination of self-regulatory and punitive practices developed during modernity to manage socially problematic prostitute populations.

The authors explore the legal and social undercurrents in Australia and Japan which are encouraging corporations to embrace broader social responsibilities. They consider a case study of sexual harassment and its regulation within Australian corporations, uncovering the legal and social conditions that have led to the adoption of sexual harassment policies. The authors propose a model for determining when corporate governance of sexual harassment is likely to be effective and test the model by reference to the experience of sexual harassment in Japan. They draw some conclusions about what the experience of corporate implementation of management of sexual harassment might mean for other areas of human rights.

The diet selected in autumn by steers fistulated at the oesophageous was studied in a subset of treatments in an extensive grazing study conducted in a Heteropogon contortus pasture in central Queensland between 1988 and 2001. These treatments were a factorial array of three stocking rates (4, 3 and 2 ha/steer) and three pasture types (native pasture, legume-oversown native pasture and animal diet supplement/spring-burning native pasture). Seasonal rainfall throughout this study was below the long-term mean and mean annual pasture utilisation ranged from 30 to 61%. Steers consistently selected H. contortus with levels decreasing from 47 to 18% of the diet as stocking rate increased from 4 ha/steer to 2 ha/steer. Stylosanthes scabra cv. Seca was always selected in legume-oversown pastures with diet composition varying from 35 to 66% despite its plant density increasing from 7 to 65 plants/m(2) and pasture composition from 20 to 50%. Steers also selected a diet containing Chrysopogon fallax, forbs and sedges in higher proportions than they were present in the pasture. Greater availability of the intermediate grasses Chloris divaricata and Eragrostis spp. was associated with increased stocking rates. Bothriochloa bladhii was seldom selected in the diet, especially when other palatable species were present in the pasture, despite B. bladhii often being the major contributor to total pasture yield. It was concluded that a stocking rate of 4 ha/steer will maintain the availability of H. contortus in the pasture.

Ethnopharmacological relevance: Traditional remedies used for treating diabetic ailments are very important in the primary health care of the people living in rural Dhemaji district of Assam, north-east India. Novel information gathered from the current survey is important in preserving folk indigenous knowledge. Materials and methods: Interviews were conducted amongst 80 households comprising of 240 individuals using semi-structured questionnaires. The focus was on plants used in treating diabetes mellitus. Results: The current survey documented 21 plant species (20 families) which are reportedly used to treat diabetes mellitus by the rural people in the study area. To the best of our knowledge, Amomum linguiforme, Cinnamomum impressinervium, Colocasia esculenta, Dillenia indica, Euphorbia ligularia, Garcinia pedunculata, Solanum indicum, Sterculia villosa and Tabernaemontana divaricata are recorded for the first time based on globally published literature as medicinal plants used for treating diabetes mellitus and related symptoms. Conclusions: The wide variety of plants that are used to treat diabetes mellitus in this area supports the traditional value that medicinal plants have in the primary health care system of the rural people of Dhemaji district of Assam. The finding of new plant uses in the current study reveals the importance of the documentation of such ethnobotanical knowledge. (C) 2011 Elsevier Ireland Ltd. All rights reserved.

El nopal, es una cactácea originaria de México, de ella se pueden obtener muchos beneficios desde alimento humano, animal y medicinal como también para la elaboración de productos con valor agregado como mermeladas, encurtidos, néctares y jugos. Este cultivo es una alternativa para mejorar los problemas que está enfrentado Nicaragua ante el cambio climático y en especial para las zonas marginales, ya que tiene una excelente adaptación a zonas áridas y semiáridas donde otros cultivos no sobrevivirían. En este trabajo se analizó la influencia de diferentes niveles de compost (0, 0.5, 1, 1.5, 2, 2.5 kg/planta) sobre la dinámica poblacional de arvenses y artrópodos asociados. El ensayo se estableció de febrero a mayo de 2009, en la finca, Guadarrama, comunidad Buena Vista Sur, ubicada en el kilometro 56½ carretera Casares, La Boquita, Diriamba, Carazo. Las variables evaluadas fueron: abundancia, div ersidad, dominancia, cobertura (%), biomasa (kg/ha), y respecto a los artrópodos, se hizo un registro con su respectiva función biológica. Los resultados obtenidos muestran que Cynodon dactylon L. arvense monocotiledónea presentó mayor abundancia con 16 individuos en el tratamiento T1 (0 kg de compost/planta), mientras que en las dicotiledóneas fué Waltheria indica L. con 4 individuos en el tratamiento T4 (1.5 kg de compost/planta), en la diversidad, el mayor número de especies se presentó a los 120 días después de la siembra, obteniéndose 4 especies en los tratamientos T2 y T6 (0.5 y 2.5 kg de compost/planta), como resultado los porcentajes mas altos de cobertura se registraron a los 90 y 120 días despues de la siembra, siendo el 5% el de mayor valor en el T1 (0 kg de compost/planta). En biomasa se encontró diferencia significativa para las arvenses monocotiledóneas, en primer lugar se encuentra el tratamiento T1 (0 kg de compost/planta) registrando el mayor volumen con 57.5 kg/ha, mientras que en las di cotiledóneas no se encontró diferencia significativa solo existió diferencia númerica presentandose con mayor valor el tratamiento T5 (2 kg de compost/ planta) con un volumen de 5 kg/ ha, por lo tanto las más dominantes fueron las monocotiledóneas. Se registraron 6 especies de artrópodos, 1 perteneciente al orden Díptera, 1 Heminóptera, 2 Lepidóptera y 2 pertenecientes al orden Orthóptera.

A sandwich-type plate with metal facings and felt core, fastened by bolts, was studied using both test and finite-element analysis. This type of plate is cheap, light, damping-effective and without pollution; therefore, it is widely used in astronautical engineering. The tests were conducted for different felt thicknesses, bolt numbers, and fastening forces. The results show that the damping depends on friction between the plates and the felt. As compared with an identical stiffness solid plate, the damping of laminated plates can be increased up to 30 times. A mesh with rectangular elements was adopted in the finite-element analysis. In accordance with the slipping mechanism, a rectangular plate clamped on one edge was analyzed with the foregoing elements to determine the resonant frequency and the damping. The difference between the calculated and tested results was within 5 percent for the resonant frequency.

Jerônimo Corte Real, poeta, músico e pintor português, nasceu nos Açores, por volta de 1530, e morreu em Évora, em 1590. Distinguiu-se graças à poesia, sendo chamado docto por Lope de Veja em oposição à classificação de divino, atribuído a Camões. Sucesso do segundo cerco de Div, publicado em 1574, é um poema épico que, segundo Aubrey Bell, é “uma excelente prosa”. Composto por vinte e dois cantos em hendecassílabos brancos, celebra a defesa de Diu, na Índia, por D. João de Mascarenhas e a libertação da praça, em 1546, por D. João de Castro. Os cantos XX e XXII descrevem as façanhas de antigos capitães e profetizam os sucesso futuros do reinado de D. Sebastião. Segundo Brunet, esta é uma edição muito rara, que foi reimpressa em Lisboa, em 1784, por Bento José de Souza Farinha. Uma tradução em língua espanhola por Pedro Padilha foi impressa em Alcalá, em 1597.

In this paper, an AC plasma arc reactorwithworkinggasofhydrogen is applied to destruct chemicalagents. The temperature attains 6000℃ in the arc area and over 2000℃ in the other space of the crucible. The Arsenic (As) contained chemical agent -Adams (DM) used in the experiment, was added into the plasmareactorwith the additives: Fe, CaO, and SiO_2, etc. Pyrolysis and destructionofchemicalagents occurs very quickly in the high-temperature reactor. Gaseous hydrogen was injected into the reactor to form a reductive environment, to reduce the formation of As_2O_3 etc. In the bottom of the crucible, the solid residues of toxicant and additives were melted and formed as vitrified slag. The off-gas was treated by a wet scrubber. The amounts of arsenic distributed in the off-gas, vitrified slag, waste water and solids (soot) were measured. The result shows DM is completely destructed in the plasmareactor. The Arsenic content in the off-gas, vitrified slag, waste water and soot are 0.052 mg/l, 3.0%, 10.44 mg/l, and 5.1% respectively, which will be disposed as the pollutant matters. The results show that the plasma technology is an environmentally friendly technology to destruct chemicals.

A temperature-controlled poolboiling (TCPB) device was developed to perform poolboiling heat transfer studies at both normal gravity and microgravity. A platinum wire of 60 μm in diameter and 30 mm in length was simultaneously used as heaters and thermometers. The heater resistance, and thus the heater temperature, was kept constant by a feedback circuit. The fluid was R113 at 0.1 Mpa and subcooled by 24 nominally for all cases. The results of the experiments at both normal gravity and microgravityin the Drop Tower Beijing were presented. Nucleate and two-mode transition boiling were observed. For nucleate boiling, the heat transfer was slightly enhanced, namely no more than 10% increase of the heat flux was obtained inmicrogravity, while the bubble pattern is dramatically altered by the variation of the acceleration. For two-mode transition boiling, about 20% decrease of the heat flux was obtained, although the part of film boiling was receded inmicrogravity. A scale analysis on the Marangoni convection surrounding bubble in the process of subcooled nucleate poolboiling was also presented. The characteristic velocity of the lateral motion and its observability were obtained approximately. The predictions consist with theexperimental observations.
