ALICE is one of four major experiments of particle accelerator LHC installed in the European laboratory CERN. The management committee of the LHC accelerator has just approved a program update for this experiment. Among the upgrades planned for the coming years of the ALICE experiment is to improve the resolution and tracking efficiency maintaining the excellent particles identification ability, and to increase the read-out event rate to 100 KHz. In order to achieve this, it is necessary to update the Time Projection Chamber detector (TPC) and Muon tracking (MCH) detector modifying the read-out electronics, which is not suitable for this migration. To overcome this limitation the design, fabrication and experimental test of new ASIC named SAMPA has been proposed . This ASIC will support both positive and negative polarities, with 32 channels per chip and continuous data readout with smaller power consumption than the previous versions. This work aims to design, fabrication and experimental test of a readout front-end in 130nm CMOS technology with configurable polarity (positive/negative), peaking time and sensitivity. The new SAMPA ASIC can be used in both chambers (TPC and MCH). The proposed front-end is composed of a Charge Sensitive Amplifier (CSA) and a Semi-Gaussian shaper. In order to obtain an ASIC integrating 32 channels per chip, the design of the proposed front-end requires small area and low power consumption, but at the same time requires low noise. In this sense, a new Noise and PSRR (Power Supply Rejection Ratio) improvement technique for the CSA design without power and area impact is proposed in this work. The analysis and equations of the proposed circuit are presented which were verified by electrical simulations and experimental test of a produced chip with 5 channels of the designed front-end. The measured equivalent noise charge was <550e for 30mV/fC of sensitivity at a input capacitance of 18.5pF. The total core area of the front-end was 2300?m × 150?m, and the measured total power consumption was 9.1mW per channel.

Este estudo exploratório, de caráter descritivo, tem como objetivos compreender a relação do Estado com a organização profissional dos assistentes sociais nas diferentes conjunturas sócio-históricas da trajetória da profissão; conhecer o contributo do associativismo sindical e profissional para a organização dos assistentes sociais em Portugal; caraterizar as diversas formas de associativismo profissional e sindical dos profissionais de Serviço Social e compreender a importância da regulação profissional para a categoria. Na trajetória do Serviço Social no nosso país, identificámos várias estruturas associativas desde os anos 50 do século XX. Apesar dessa diversidade ao nível da organização profissional, nos últimos anos tem sido o projeto de constituição da ordem o que tem congregado os profissionais de Serviço Social, embora de forma fragmentada. Em Portugal não existe um estatuto jurídico de regulação da profissão de assistente social, sendo do interesse dos profissionais, utentes e sociedade que o mesmo seja efetivado. A criação de uma ordem profissional poderá vir a fortalecer o trabalho dos profissionais de Serviço Social, bem como proteger e regulamentar o exercício profissional e a formação académica. Com a erosão do Estado Social, as relações de trabalho tendem a ser desregulamentadas e flexibilizadas, subsistindo a precariedade e o desemprego. O enfrentamento a estas questões por parte do movimento associativo é ténue e a sua não articulação fragiliza a proteção dos profissionais, como indiciam a subsistente ausência da constituição da ordem profissional e a extinção do Sindicato Nacional de Profissionais de Serviço Social, apesar do ressurgimento do associativismo sindical durante o presente ano (2013). As condições atuais diferem das existentes aquando do processo de obtenção da licenciatura e estruturação e implementação das carreiras profissionais de Serviço Social que potenciaram e galvanizaram os assistentes sociais. A categoria profissional apresenta-se desmobilizada e com pouco poder reivindicativo, e as associações profissionais e sindicais vivem com constrangimentos financeiros, funcionando em regime de voluntariado, o que denota a insipiência da sua estrutura organizativa. A atual conjuntura justificaria uma maior convergência, debate e processos de resistência por parte das estruturas associativas face ao agravamento de políticas baseadas na austeridade, que têm reflexos no mercado de trabalho, formação e organização profissional. Parece justificar-se a existência de estratégias articuladas com maior clareza sobre o projeto para a categoria, apostando num debate que se faça com os seus diversos intervenientes. Desta forma, o associativismo poderá constituir uma alavanca que confira maior dinamismo às suas estruturas organizacionais, maior visibilidade e presença pública da categoria, mas também uma maior solidez das suas organizações, que não sendo corporativas ou elitistas, salientem o primado da ética do serviço sobre a ética do ganho. / This descriptive exploratory study aims to understand the relationship between the State and the professional organisation of the social workers in the different social-historical situations of the profession course; to know the contribute of the unions and professional membership drive to the organisation of the social workers in Portugal; to characterise the several ways of the social workers’ professional and union membership drive and to understand the importance of the professional regulation for the area. In the Social Service trajectory in our country, we have identified several associative structures since the 1950s. Despite this diversity concerning the professional organisation, the project of constituting the professional order has been responsible for the social workers’ congregation in the past years, although in a fragmented way. In Portugal, there is not a legal status of regulation of the social workers’ profession, and it is of the interest of the professionals, users and society that this may be brought about. The creation of a professional order may strengthen the activity of the social workers, as well as it may protect and regulate the profession exercise and the university education. With the Social State’s erosion, the work relationships tend to be deregulated and softened, persisting the job insecurity and the unemployment. The associative movement does not strongly face these issues, and its non-articulation weakens the professionals’ protection, as the permanent absence of the professional order creation and the extinction of the National Social Workers Union show, despite the reappearance of the union membership drive during the present year (2013). The current conditions are not equal to the ones existent in the process of obtaining the university degree and the structuring and implementing of professional careers in the Social Service area, which have strengthened and galvanised the social workers. The professional category is not mobilised and it has few claimable power; the professional and unions’ associations live with financial problems, functioning in a volunteering regime, which shows the insipience of its organisation structure. The current situation would justify a bigger convergence, debate and resistance processes on behalf of the associative structures regarding the worsening of policies based on austerity – this has consequences in the work market, training and professional organisation. It seems to be pertinent the existence of strategies articulated in a clearer way about the project for this professional area, investing in a debate among its several participants. Therefore, the professional membership drive may constitute a lever that can give more dynamism to its organisational structures, a bigger visibility and public presence of the area, but also a stronger solidity in its organisations which, being not corporative or elitist, may highlight the service’s ethics over the profit’s ethics.

NOAA’s National Centers for Coastal Ocean Science (NCCOS) conducts and supports research, monitoring, assessments, and technical assistance to meet NOAA’s coastal stewardship and management responsibilities. In 2001 the Biogeography Branch of NCCOS partnered with NOAA’s National Marine Sanctuary Program (NMSP) to conduct biogeographic assessments to support the management plan updates for the sanctuaries. The first biogeographic assessment conducted in this partnership focused on three sanctuaries off north/ central California: Cordell Bank, Gulf of the Farallones and Monterey Bay. Phase I of this assessment was conducted from 2001 to 2004, with the primary goal to identify and gather the best available data and information to characterize and identify important biological areas and time periods within the study area. The study area encompasses the three sanctuaries and extends along the coastal ocean off California from Pt. Arena to Pt. Sal (35°-39°N). This partnership project was lead by the NCCOS Biogeography Branch, but included over 90 contributors and 25 collaborating institutions. Phase I results include: 1) a report on the overall assessment that includes hundreds of maps, tables and analyses; 2) an ecological linkage report on the marine and estuarine ecosystems along the coast of north/central California, and 3) related geographic information system (GIS) data and other summary data files, which are available for viewing and download in several formats at the following website: http://ccma.nos.noaa.gov/products/biogeography/canms_cd/welcome.html Phase II (this report) was initiated in the Fall of 2004 to complete the analyses of marine mammals and update the marine bird colony information. Phase II resulted in significant updates to the bird and mammal chapters, as well as adding an environmental settings chapter, which contains new and existing data and maps on the study area. Specifically, the following Phase II topics and items were either revised or developed new for Phase II: •environmental, ecological settings – new maps on marine physiographic features, sea surface temperature and fronts, chlorophyll and productivity •all bird colony or roost maps, including a summary of marine bird colonies •updated at-sea data CDAS data set (1980-2003) •all mammal maps and descriptions •new overall density maps for eight mammal species •new summary pinniped rookery/haulout map •new maps on at-sea richness for cetaceans and pinnipeds •most text in the mammal chapter •new summary tables for mammals on population status and spatial and temporal patterns
