Executive Summary: Observations show that warming of the climate is unequivocal. The global warming observed over the past 50 years is due primarily to human-induced emissions of heat-trapping gases. These emissions come mainly from the burning of fossil fuels (coal, oil, and gas), with important contributions from the clearing of forests, agricultural practices, and other activities. Warming over this century is projected to be considerably greater than over the last century. The global average temperature since 1900 has risen by about 1.5ºF. By 2100, it is projected to rise another 2 to 11.5ºF. The U.S. average temperature has risen by a comparable amount and is very likely to rise more than the global average over this century, with some variation from place to place. Several factors will determine future temperature increases. Increases at the lower end of this range are more likely if global heat-trapping gas emissions are cut substantially. If emissions continue to rise at or near current rates, temperature increases are more likely to be near the upper end of the range. Volcanic eruptions or other natural variations could temporarily counteract some of the human-induced warming, slowing the rise in global temperature, but these effects would only last a few years. Reducing emissions of carbon dioxide would lessen warming over this century and beyond. Sizable early cuts in emissions would significantly reduce the pace and the overall amount of climate change. Earlier cuts in emissions would have a greater effect in reducing climate change than comparable reductions made later. In addition, reducing emissions of some shorter-lived heat-trapping gases, such as methane, and some types of particles, such as soot, would begin to reduce warming within weeks to decades. Climate-related changes have already been observed globally and in the United States. These include increases in air and water temperatures, reduced frost days, increased frequency and intensity of heavy downpours, a rise in sea level, and reduced snow cover, glaciers, permafrost, and sea ice. A longer ice-free period on lakes and rivers, lengthening of the growing season, and increased water vapor in the atmosphere have also been observed. Over the past 30 years, temperatures have risen faster in winter than in any other season, with average winter temperatures in the Midwest and northern Great Plains increasing more than 7ºF. Some of the changes have been faster than previous assessments had suggested. These climate-related changes are expected to continue while new ones develop. Likely future changes for the United States and surrounding coastal waters include more intense hurricanes with related increases in wind, rain, and storm surges (but not necessarily an increase in the number of these storms that make landfall), as well as drier conditions in the Southwest and Caribbean. These changes will affect human health, water supply, agriculture, coastal areas, and many other aspects of society and the natural environment. This report synthesizes information from a wide variety of scientific assessments (see page 7) and recently published research to summarize what is known about the observed and projected consequences of climate change on the United States. It combines analysis of impacts on various sectors such as energy, water, and transportation at the national level with an assessment of key impacts on specific regions of the United States. For example, sea-level rise will increase risks of erosion, storm surge damage, and flooding for coastal communities, especially in the Southeast and parts of Alaska. Reduced snowpack and earlier snow melt will alter the timing and amount of water supplies, posing significant challenges for water resource management in the West. (PDF contains 196 pages)

Os constituintes começaram a apresentar os pedidos de Destaques para votação das emendas em separados. O prazo para a entrega dos requerimentos vai até o dia 22.7.1988 a meia-noite. Cada constituinte tem o direito de apresentar 4 (quatro) Destaques. O primeiro a chegar foi o Líder do PMDB, Nelson Jobim. Até o final da tarde mais de 180 constituintes já tinham apresentado seu Destaque, como foi o caso dos deputados Francisco Kuster (PMDB-SC) e Nelson Frederich (PMDB-PR). O Centrão que fez algumas reuniões anteriormente, já sabe o que quer retirar do texto e acredita que têm votos suficientes para isto. Os constituintes considerados progressistas acham que os temas que foram objeto de acordo no 1º Turno devem permanecer no texto e acreditam que pouca coisa deve ser modificada. Jair Menegheli (Presidente da CUT) disse que os sindicalistas já estão preparados para a defesa de seus direitos no 2º Turno.

Techniques are described for preparing acetate peels of sectioned valves of ocean quahogs, Arctica islandica, for age determinations. The respective sequence of preparation begins by sectioning left valves oriented to include a single hinge tooth, bleaching to remove the heavy periostracum, embedding the valves in an epoxy resin, grinding and polishing the embedments to a high luster, etching the exposed cut valve surfaces, and applying sheet acetate with acetone. Annuli are clearly defined relative to growth increments in the peel preparations for all sizes and ages of ocean quahogs. (PDF file contains12 pages.)

A Sessão do Plenário da Constituinte começou com os líderes de diversos partidos se revesando na tribuna a favor e contra a proposta do Centrão para a mudança do Regimento Interno. Após muita confusão e debate, é posta em votação a proposta do Centrão. O líder Mário Covas comunica que o PMDB se retira da votação. O PMDB e os Partidos Progressistas se retiram e os constituintes começam a votação. O Centrão está sozinho no Plenário. As galerias do Plenário se enchem com participantes de um evento da CUT, CGT e Contag. Vaias e chuvas de papel cobrem o Centrão a cada voto. Finda a votação, a mudança do Regimento é aprovada. Diante da impossibilidade de acordo, o presidente do PMDB, sugere que a Mesa faça um substitutivo com as alterações objeto de divergência. Ulysses Guimarães sugere a apresentação de um projeto de resolução para tentar o acordo entre os constituintes. Emendas e destaques poderão aperfeiçoar a proposta aprovada pelo Centrão.

O projeto da Mesa da Constituinte, entrou em negociação logo após a aprovação do projeto do Centrão, que tinha o mesmo objetivo: alterar o Regimento Interno. Agora prevalece o projeto de resolução da Mesa da Constituinte que deve ser votado terça ou quarta feira da próxima semana. Os principais pontos são: Ficam mantidas as emendas coletivas assinadas por 280 constituintes; as emendas coletivas podem ser a títulos, mas a votação será feita por capítulos; as propostas com maior número de assinaturas terão preferência para votação; o prazo para apresentação de emendas ao projeto de Constituição será de 7 dias; as emendas velhas não serão aceitas; cada constituinte pode apresentar 4 emendas e 6 destaques. A maioria dos constituintes já sabe o que quer manter e o que quer modificar no projeto aprovado pela Sistematização. Os movimentos sindicais se reunirão durante todo o dia de ontem no Congresso Nacional. Eles querem que o Plenário mantenham os avanços conseguidos na Comissão de Sistematização

Ainda não saiu o acordo sobre a estabilidade no emprego. Sindicalistas e constituintes se reúnem para discutir as propostas apresentadas. Nesta reunião, os constituintes ouviram os presidentes da CUT e da CGT e não chegaram a nenhum acordo. Em outra reunião, participou o presidente dos Metalúrgicos de São Paulo. Mas, também não se chegou a um acordo. Manifestação realizada por diversas entidades de classes dá uma abraço a Constituinte. Dando-se as mãos, povo e líderes sindicais deram a volta ao prédio do Congresso, para pedir aos constituintes que garantam os avanços sociais já aprovados nas etapas anteriores. A garantia do direito do preso é votada, estabelecendo de que forma uma pessoa deve ser presa. O destaque que exige a ordem judiciária escrita para se efetuar qualquer prisão em território nacional foi aprovado. O direito de propriedade será votado a seguir.

In account of the decision of the IBSFC (International Baltic Sea Fisheries Commission) to admit alternative codend constructions to the presently legal of diamond meshes with 120 mm mesh opening, since seven years a vivid research activity is encouraged at the fishing technology institutions around the Baltic. Though a center of gravity in this field of research lies in the EUproject BACOMA (participants Finland Sweden, Denmark) also the corresponding national institutes of other Baltic countries (Germany, Poland, Russia) have been active with similar investigations. German experiments in 1999 dealt with the effect of the use of netting made of double instead of single yarn on the selectivity. Further research was done on modifications of codends made from netting turned 90° from its original orientation and on simplified versions of the so-called Multipanel codend which consists of three equal diamond and three square mesh panels. The experiments demonstrated on the one hand a definite deterioration of the selective properties in a codend made from double instead of single yarn. Constructional changes in codends made from netting turned 90° on the other hand brought a further improvement of the selectivity of such codends. Finally, the investigations on the Multipanel codend revealed the overwhelming influence of the square mesh panels on the selectivity success. If in a conventional diamond codend three windows are cut out starting 50 cm from the real end of the codend in such a way that the remaining parts have the same breadth as the square mesh panels to insert, the selective effect of such a codend is remarkably improved. According to further preliminary tests this seems to be nearly independent from the type of material used.

The fishery ministers of the EU agreed in their yearly pre-Christmas marathon session on 18th and 19th Dec. 1997 on next year’s TACs and country quota. Main decision was the increase of the TAC for North sea cod and a smaller than feared cut of cod TACs in the West of Scotland zone, the Irish Sea and the English Channel. For the first time ministers set country quota for horse mackerel; until 1997 there had been - with the exception for Portugal and Spain - only a common quota. Also for the much disputed sandeel fishery a TAC of 1 mio. t was finally established, as well as for bluefin tuna and swordfish in the Atlantic and Mediterranean. For 1998 the EU member countries dispose of a total catch quota of 4.46 mio. t in EU waters, and together with quota in third country waters of 5.2 mio. t. Of this total quota, 3.16 mio. t are fish for human consumption and 2.1 mio. t fish for industrial purposes.

The preliminary results obtained from the study of stomach contents of specimens of Gymnarchus niloticus of a size ranging from 56 cm (66 grams) to 152 cm (12.0 kg.) from August to December, 1982 indicate for these sizes an exclusively piscivorous diet. The predominant prey species in Lake Chad are Tilapia/Sarotherodon , and Clarias . The prey is often cut in two parts before it is swallowed. Small prey may be swallowed whole. The implication of this prey capture method on prey-predator relationship and therefore the impact of the predator is discussed. The breeding season of Gymnarchus niloticus in Lake Chad has been deduced from observation of changes in gonad maturity stages and the results indicate that breeding takes place between August and November. Data are also presented on the fecundity, size of ripe eggs and probable size at maturity

A biosensor based on imaging ellipsometry (BIE) has been developed and validated in 169 patients for detecting five markers of hepatitis B virus (HBV) infection. The methodology has been established to pave the way for clinical diagnosis, including ligand screening, determination of the sensitivity, set-up of cut-off values (CoVs) and comparison with other clinical methods. A matrix assay method was established for ligand screening. The CoVs of HBV markers were derived with the help of receiver operating characteristic curves. Enzyme-linked immunosorbent assay (ELISA) was the reference method. Ligands with high bioactivity were selected and sensitivities of 1 ng/mL and 1 IU/mL for hepatitis B surface antigen (HBsAg) and surface antibody (anti-HBs) were obtained respectively. The CoVs of HBsAg, anti-HBs, hepatitis B e antigen, hepatitis B e antibody and core antibody were as follows: 15%, 18%, 15%, 20% and 15%, respectively, which were the percentages over the values of corresponding ligand controls. BIE can simultaneously detect up to five markers within 1 h with results in acceptable agreement with ELISA, and thus shows a potential for diagnosing hepatitis B with high throughput.

Live African prawns Macrobrachium vollenhovenii were collected from Asejire reservoir (Nigeria) by trapping. After acclimatization, the prawns were differently amputated: some had their eye-stalks cut; some had their chelae cut; some had both eyestalks and chelae cut while some were intact which served as the control. Each set was placed under different levels of crude protein viz 15%; 20%; and 25%. Weekly weight changes were monitored. Results obtained were subjected to statistical analysis including analysis of variance (ANOVA). The results showed that prawns fed with 20% crude protein had the best growth rate. Specimens with the eyestalk and chelae removed also showed superior growth when compared with the others. Specimens that had their eyestalks removed were able to feed for 18 hours in the day while those with intact body fed for 6 hours during the same period. The amputation of the chelate appendages reduced considerably the cannibalistic urge in the prawns. This enabled a high number of prawns to be grown in the experimental tanks
