Lawrence Livermore National Laboratory Safeguards and Security quarterly progress report ending March 31, 1996
LLNL carries out safeguards and security activities for DOE Office of Safeguards and Security (OSS) and other organizations within and outside DOE. LLNL is supporting OSS in 6 areas: safeguards technology, safeguards and materials accountability, computer security--distributed systems, complex-wide access control, standardization of security systems, and information technology and security center. This report describes the activities in each of these areas
Pembuatan Metil Ester Sulfonat dari Refined Bleached Deodorized Stearin Minyak Sawit Menggunakan Oleum
PEMBUATAN METIL ESTER SULFONAT DARI REFINED BLEACHED DEODORIZED STEARIN MINYAK SAWIT MENGGUNAKAN OLEUM. Telah dilakukan proses pembuatan metil ester sulfonat dengan menggunakan oleum sebagai sumber SO3. Beberapa variabel proses seperti suhu dan perbandingan mol antara SO3 dan metil ester telah dilakukan untuk mendapatkan kondisi optimal untuk proses sulfonasi yang menggunakan reaktor falling film. Kondisi proses yang optimal diperoleh pada suhu antara 80 0C hingga 90 0C. Perbandingan mol reaktan 1,2 menghasilkan kandungan bahan aktif sebesar 93%. Metil ester sulfonat yang diperoleh dengan bilangan iod 1,15, tegangan permukaan 29 dyne/cm dan 180 klett sebagai indikasi warna
Lawrence Livermore National Laboratory safeguards and security quarterly progress report to the U.S. Department of Energy. Quarter ending September 30, 1996
The paper describes tasks undertaken in each of the following areas: Safeguards technology program (STP); Safeguards and material accountability (SMA); Computer security, distributed systems; Complex-wide access control system (CWAC); and Standardization of security systems (SSS). The STP develops advanced, nondestructive analysis technology for measurement of special nuclear materials. Work focuses on R and D relating to X- and gamma-ray spectrometry and to development of computer codes for interpreting the spectral data obtained by these techniques. The SMA is concerned with four areas: insider protection; material accountability; planning and evaluation; and information security. The Computer Security Technology Center provides expertise and solutions to the many information security problems present in today`s computer systems and networks. Incidents of intrusions, computer viruses, the purposeful replacement of legitimate software for illegal purposes, and similar acts are being addressed by the creation of security software, the delivery of incident response expertise, and research and development into secure systems. The purpose of the CWAC is to develop an approach that will allow visitors to use their DOE standard badge in access control systems throughout the DOE complex. The purpose of the SSS project is to support the standardization of security systems to meet DOE orders and requirements, and to support the DOE in offering relevant security technology and capabilities to Federal standardization efforts

Diagnóstico do meio físico da bacia hidrográfica do Rio do Imbé - RJ: aplicação de metodologia integrada como subsídio ao manejo de microbacias.
O Diagnóstico do Meio Físico da Bacia do Rio do Imbé (BHRI) integra os estudos que subsidiam o projeto Manejo Sustentável de Recursos Naturais em Microbacias do Norte-Noroeste Fluminense - SMH-SEAAPI/GEF (Global Enviroment Facility), cujo principal objetivo é apoiar produtores rurais de base familiar na autogestão dos recursos naturais, visando o desenvolvimento rural baseado em um modelo de agricultura socioambientalmente sustentável. A metodologia adotada partiu da integração da base cartográfica e dos dados digitais de mapeamentos temáticos do meio físico (clima, recursos hídricos, geologia, geomorfologia, solos e uso e ocupação das terras). Adotou-se no presente estudo a escala 1:250.000, compatível com a maioria dos dados secundários, que foram transformados para uma mesma projeção cartográfica e inseridos em uma base de dados digital. Inicialmente, foi realizada a síntese dos dados de solos e geomorfologia para a identificação e delimitação de unidades morfopedológicas. Em seguida, essas unidades foram agrupadas em seis zonas agroecológicas, considerando as potencialidades e fragilidades dos recursos naturais, os padrões de uso e o estado de degradação das terras. As zonas foram descritas e caracterizadas com base no conjunto de dados temáticos disponível e complementados com as informações levantadas em campo. O trabalho de campo foi orientado para verificação da diversidade dos aspectos físicos, das atividades antrópicas e dos problemas de degradação e conflitos relacionados ao uso dos recursos naturais. Foram considerados ainda o histórico socioeconômico e ambiental da região e a percepção dos atores locais com relação aos aspectos mencionados. Os resultados evidenciaram que a BHRI, face à singular interação dos aspectos fisiográficos e antrópicos, possui uma diversidade ambiental contrastante, apresentando diferentes potencialidades de uso e níveis de fragilidade. Contudo, o diagnóstico do meio físico, obtido segundo a metodologia apresentada, poderá constituir-se em um instrumento importante para subsidiar a tomada de decisões no que se refere às estratégias de planejamento, manejo adequado, monitoramento e avaliação dos recursos naturais, a serem adotados pelo projeto
