Women on March in Goa : the gender transition in Higher Education after the Statehood

This paper attempts to address the interesting phenomenon of dominance of women in higher educational sector of Goa-a remarkable postcolonial event which occurred after Goa attained statehood in 1987. The Indian state of Goa has been experiencing a rapid socio-economic and cultural transformation. At present it enjoys many of the highest human development indicators in India, matching some of the developed countries. Its’ projected population at present is 1.45 million (Indian decennial census 2001 reported 1.348 million). When the Portuguese rule ended, the literacy was just 31 % whereas it stood at 82 % in 2001. Goa is a highly urbanized state in India. In 1960 there were just five towns and 15 % urban population. In 2001 the figures were, 44 towns and 50 % urban population. On economic front Goa has made tremendous progress mainly on account of the growth of mining, tourism and the service sector. Tourist arrivals in Goa have exceeded the state’s population from 2001. The Gross state domestic product (GSDP) at current prices in 2003-04 was Indian Rupees (Rs.) 96570 million, up from Rs. 3930 million when Goa became a full-fledged state. The banks are flush with funds indicating a booming economy. Goa has lowest birth and death rates and a life expectancy of 68 years for the males and 72 for females. The sex ratio however has shown a declining trend since 1960, from 1066 to 960 in 2001 (Table 1).The sex ratio for 0-6 years age group was 933. On this background we intend to examine the changing pattern of female education in Goa.

¿Quién debe ser el intérprete supremo de la Constitución?: el precedente constitucional en la acción de amparo en el Ecuador

La regulación jurídica es contradictoria respecto de la validez de la jurisprudencia como fuente del derecho. Sin embargo, los cambios constitucionales que se vienen dando desde las reformas de 1992 y 1996, y la Constitución de 1998, abren la posibilidad de la construcción, a través del diseño legislativo o judicial, de lo que se ha denominado “precedente constitucional”. En este trabajo se busca explicar la naturaleza de este precedente respecto de las sentencias de amparo constitucional; evidenciar los modelos de regulación y determinar dentro de cuál está o debería estar el caso ecuatoriano; determinar cuáles son los fines que se buscan con su aplicación a los casos concretos. Las grandes líneas de abordaje de este trabajo son la interpretación constitucional, el análisis de la jurisprudencia y las legislaciones comparadas, y el nuevo rol que los jueces tienen como creadores de derecho. El objeto principal de este estudio será el análisis de la problemática del precedente constitucional para dar respuesta a las siguientes preguntas: ¿cómo se aplica el precedente de manera general y cómo debe aplicárselo a las sentencias de amparo constitucional?; y, ¿cómo esta aplicación puede fortalecer la justicia constitucional y al Tribunal Constitucional como intérprete supremo de la Constitución? En definitiva, esta obra retoma la cuestión discutida entre Kelsen y Schmit: quién debe ser el defensor de la Constitución?, Pregunta reformulada frente a la nueva realidad constitucional: “¿Quién debe ser el intérprete supremo de la Constitución?: el precedente constitucional en la acción de amparo en el Ecuador.”

Photocatalytic degradation of humic acid in saline waters. Part 1. Artificial seawater: influence of TiO2, temperature, pH, and air-flow

We report the first systematic study on the photocatalytic oxidation of humic acid (HA) in artificial seawater (ASW). TiO2 (Degussa P25) dispersions were used as the catalyst with irradiation from a medium-pressure mercury lamp. The optimum quantity of catalyst was found to be between 2 and 2.5 g l(-1); whiled the decomposition was fastest at low pH values (pH 4.5 in the range examined), and the optimum air-flow, using an immersion well reactor with a capacity of 400 ml, was 850 ml min(-1). Reactivity increased with air-flow up to this figure, above which foaming prevented operation of the reactor. Using pure. oxygen, an optimal flow rate was observed at 300 nil min(-1), above which reactivity remains essentially constant. Following treatment for 1 h, low-salinity water (2700 mg l(-1)) was completely mineralised, whereas ASW (46000 mg l(-1)) had traces of HA remaining. These effects are interpreted and kinetic data presented. To avoid problems of precipitation due to change of ionic strength humic substances were prepared directly in ASW, and the effects of ASW on catalyst suspension and precipitation have been taken into account. The Langmuir-Hinshelwood kinetic model has been shown to be followed only approximately for the catalytic oxidation of HA in ASW. The activation energy for the reaction derived from an Arrhenius treatment was 17 ( +/-0.6) kJ mol(-1). (C) 2003 Elsevier Science Ltd. All rights reserved.

IR spectrum and radiative forcing of CF4 revisited

Carbon tetrafluoride (CF4) is included as a greenhouse gas within the Kyoto Protocol. There are significant discrepancies in the reported integrated infrared (IR) absorption cross section of CF4 leading to uncertainty in its contribution to climate change. To reduce this uncertainty, the IR spectrum of CF4 was measured in two different laboratories, in 0 933 hPa of air diluent at 296 +/- 2K over the wavelength range 600-3700 cm(-1) using spectral resolutions of 0.03 or 0.50 cm(-1). There was no discernable effect of diluent gas pressure or spectral resolution on the integrated IR absorption, and a value of the integrated absorption cross section of (1.90 +/- 0.17) x 10(-16) cm(2) molecule(-1) cm(-1) was derived. The radiative efficiency (radiative forcing per ppbv) and GWP (relative to CO2) of CF4 were calculated to be 0.102 W m(-2) ppbv(-1) and 7200 (100 year time horizon). The GWP for CF4 calculated herein is approximately 30% greater than that given by the Intergovernmental Panel on Climate Change (IPCC) [ 2002] partly due to what we believe to be an erroneously low value for the IR absorption strength of CF4 assumed in the calculations adopted by the IPCC. The radiative efficiency of CF4 is predicted to decrease by up to 40% as the CF4 forcing starts to saturate and overlapping absorption by CH4, H2O, and N2O in the atmosphere increases over the period 1750-2100. The radiative forcing attributable to increased CF4 levels in the atmosphere from 1750 to 2000 is estimated to be 0.004 W m(-2) and is predicted to be up to 0.033 W m(-2) from 2000 to 2100, dependent on the scenario.

Synthesis, crystal structure and reactivity of copper(II) complexes of tetradentate N2S2 donor ligands

Two new hexa-coordinated mononuclear copper(II) complexes of two ligands L-1 and L-2 containing NSSN donor sets formulated as [Cu(L)(H2O)(2)](NO3)(2) [1a, L = 1,2-bis(2-pyridylmethylthio)ethane (L-1), 1b L = 1,3-bis(2-pyridyl-methylthio)propane (L-2)] were synthesized and characterized by physico-chemical and spectroscopic methods. In 1a the single crystal X-ray crystallography analysis showed a distorted octahedral geometry about copper(II) ion. The crystal packing evidences pairs of complexes arranged about a center of symmetry and connected through a H-bond occurring between aquo ligands and nitrate anions. On reaction with chloride and pseudohalides (N-3(-) and SCN-), in acetonitrile at ambient temperature. complexes 1 changed to monocationic penta-coordinated mononuclear copper(H) species formulated as [Cu(L)(Cl)]NO3 (2), [Cu(L)(N-3)]NO3 (3). and [Cu(L)(SCN)]NO3 (4). These copper(II) complexes have been isolated in pure form from the reaction mixtures and characterized by physico-chemical and spectroscopic tools. The solid-state structure of 2a, established by X-ray crystallography, shows a trigonal bipyramidal geometry about the metal ion with a trigonality index (tau) of 0.561. (C) 2009 Elsevier B.V.

Provenance of chalk tesserae from Brading Roman Villa, Isle of Wight, UK

Thin section petrographical analysis of chalk tesserae at Brading Roman Villa, Isle of Wight, England, identifies a range of planktonic foraminifera and the calcareous algal cyst Pithonella that identify the Late Cenomanian Rotalipora cushmani Biozone (BGS Foraminiferal Biozones 4iii to 7). The local chalk crop to the north of the villa includes rocks of R. cushmani Biozone age, and indicates a likely local, rather than long distance, source for the tesserae. Microfossils provide a powerful tool for identifying the provenance of artefacts in Roman Britain.

Exact design manifold control of a class of nonlinear singularly perturbed systems

The integral manifold approach captures from a geometric point of view the intrinsic two-time-scale behavior of singularly perturbed systems. An important class of nonlinear singularly perturbed systems considered in this note are fast actuator-type systems. For a class of fast actuator-type systems, which includes many physical systems, an explicit corrected composite control, the sum of a slow control and a fast control, is derived. This corrected control will steer the system exactly to a required design manifold.
