This article demonstrates the practices and waste management policies (WMP), adopted by companies participating in the Corporate Sustainability Index (CSI) of the state of the stock exchange in Sao Paulo, Brazil (BOVESPA). It also presents the results that these practices provided for these companies and for the environment. The study was conducted in the two companies with the highest sales in the year 2013 in the fields of power generation, financial institutions, water and wastewater, pulp and paper, telephony and highway concession. The search strategy was divided into five stages and through the 2013 year of sustainability reporting content analysis, it was found that companies that already have advanced and positive practices with respect to sustainability, serve as reference and stimulus for other companies adopt these concepts. The survey also found that companies in the electricity sector that have the same types of waste, have different management practices, a fact confirmed in telephone companies too, highway concessions and financial institutions. It also showed that the adoption of WMP practices provided advantages in terms of cost reduction and revenue growth for all companies surveyed and mostly, all these gains also reflected positive results for the environment and nature.

The theme of sustainable development has increasingly impacted the spheres of Brazilian society and has contributed to greater awareness to the need of natural resources conservation as well as issues on how to continue promoting socio-economic development of regions. One of the key issues for sustainable development is the generation of electricity with more use of renewable sources and, therefore, less environmental degradation. In this scenario, historically, Paraná State of Brazil has been one of the largest producers of electricity in the country, almost entirely from hydraulic source, due to the large existing river basin in the state. However, the use of this source in Brazil is declining due to depletion of water potential and also the pressure of society with respect to environmental, social and economic impacts caused by damming of rivers and flooding of cities and areas to form large reservoirs. To overcome these limitations, other sources have been studied and used, such as biomass and wind. Photovoltaic generation has been contemplated in Brazilian government policies only to supply electricity with off-grid systems in remote locations. However, due to the recent Resolution 482/2012 of ANEEL (Brazilian Electricity Regulatory Agency), which establishes rules for micro and mini-generation of electricity, it is possible that consumers install grid connected photovoltaic systems up to 1 MWp, as have been widely used in the urban environment installed or integrated on roofs as a form of distributed generation, particularly in Europe, where counts with installed capacity in GW range, while in Brazil it counts only with a few MW. Given this new perspective of growth of the Brazilian photovoltaic electricity generation this paper presents the potential of solar photovoltaic power generation in Paraná State, Brazil, with a comparative analysis with the potential presented by some European countries.

This paper describes the implementation of proposed KBS automatically aware of context or constraints in which the user has to deal with to come up with intelligent DSS. Context is a fundamental information resource that has to do closely with the use of knowledge. The proposed KBS is equipped with the Expert system (ES) providing Decision Support system (DSS), aimed for realizing effective utilization of captured CNC operator knowledge when they assess machining parameters within product data. The newest module in the proposed KBS is equipped with automated contextbased DSS constructed from incoming task restraints and other related machining aspects, such as machining parameter values, cutting tool, workpiece material, etc. In this work, the discussions are focussing on CNC milling operations. According to the implementation result, CNC operators have shown enhanced accuracy on defining machining parameter values with respect to specific constraints.

External communications is a critical element in the U.S. Navy design and utilization of a ship's combat system. The communications antenna system is a key factor in attainment of reliable circuit performance and reduction of electromagnetic interference (EMI). To maintain pace with improved ship manufacturing techniques and construction materials, along with design efforts to reduce topside generated EMI/RFI effects, an improved antenna design must also evolve. With the ever increasing complexity in the integration of the topside environment, the RF aspects of the antenna designs must be augmented by detailed analysis of the operating environment and the mechanical design if the goals of reliability and quality performance are to be achieved. The Naval Electronic systems Command has developed a new “Broadband HF Communications Antenna.” This paper traces the design evolution and describes the processes in determining current design deficiencies, the design objectives to correct these deficiencies and the results obtained.

The critical minerals industries in Indonesia may pose possible environmental and human health risks due to the release of pollutants into soil, water, and air, as well as the use of materials and energy. This study investigates the possible environmental and human health impacts of Indonesia's nickel, gold, copper, tin, and bauxite mining and processing industries. This study utilizes the latest version of the OpenLCA software, version 2.0, in combination with the Ecoinvent 3.8 database. To evaluate potential environmental consequences and health effects on humans, CML-IA Baseline and Environmental Priority Strategies (EPS) are employed in product development. The EPS system was developed utilizing a hierarchical methodology with the objective of furnishing the product developer with data regarding the financial impact of human health impairment resulting from a particular product development. The production of one tonne of gold, nickel, bauxite, tin, and copper results in the emission of 7.34.E+07, 4.61.E+04, 3.10.E+04, 1.02.E+04, 8.01.E+03 kg CO₂ eq/t, respectively, contributing to global warming. This production is associated with asthma cases of 7.79.E+01 (gold industry), 2.21.E−03 (copper industry), 1.81.E−03 (tin industry), 9.21.E−04 (nickel industry), and 4.71.E−06 (bauxite industry) Personyears/t. Electricity consumption and the release of carbon dioxide are the main factors contributing to global warming. The primary cause of asthma cases is the utilization of fuel oil and electricity. Power plant chimneys can employ various technologies, such as cyclones, bag filters, and scrubbers, to mitigate the release of polluting gas emissions. The critical mineral industry must prioritize handling and governing of steam power facilities to minimize their negative effects on the environment and human health. © 2024 The Authors

Microalgae is one of the main substances used in the biomass production process in order to produce environmentally-friendly biofuels. Microalgae biomass production process influenced by several of environmental factors, specifically, the use of catalysts which play an important role in order to produce a significant yield of microalgae biomass. The use of catalyst should obey the rules of green chemistry and also minimalizing the negative impact to the environment. This paper aims to compare the effectiveness of the use of three types of catalysts: biocatalysts (enzymes), homogeneous and heterogeneous catalysts. These three types catalyst then used as additive components in the transesterification process to produce microalgae biomass. This study was conducted by collecting data related to the yield of biomass contained in several scientific journals through the Science Direct website using the systematic literature review method. The data processing involves a semi meta-analysis method using the one-way Analysis of Variance (ANOVA) test, followed by the Least Significant Difference (LSD) test using Fisher’s method.

In addition to ASNE which he joined in 1977 he is a member of IEEE and ASE and has had several technical papers published on Radar Radar Processing and Transmission Lines. Mr. Bradford E. Kruger:is a Senior Member of the Technical Staff at ITT Gilfillan Los Angeles Calif. He received his B.S.E.E. and M.S.E.E. degrees from the University of California at Berkeley in 1955 and 1956 respectively and has been with Gilfillan since then. For the past fifteen years he has been involved in the concept formulation and design of numerous radar systems for the Army Navy and Marine Corps. Most recently he has been the Principal Radar Systems Engineer for the SSURADS then the DDGX Program. In addition to ASNE which he joined in June 1980 he is a member of IEEE and holds several patents in Radar and Antenna Technology.

The best topside location for an antenna is on top of the highest mast on the ship, thus affording all-around coverage and minimum interference. However, usually only one antenna can occupy that site. Modern naval combatants have numerous antennas, and the necessary compromises in mounting all of them means that even the best site is often electro-magnetically compromised by adjacent structures and other antennas. A contrary approach is to mount larger antennas lower, and to design the ship to minimize blockage. This is “The UNIMAST Concept,” which argues for a single mast on which are mounted all the ship's major rotating surveillance antennas. The larger antennas rotate around the lower part of the mast, while lighter antennas, e.g., surface search, are sited above. This paper discusses the degradation of sidelobes due to present topside design and numerically relates degradation to Electronic Counter-Countermeasures (ECCM) performance. Removal of that degradation via the UNIMAST Concept requires that a device known as an Annular Rotary Coupler (ARC) be used. The development of just such a high power, wide-band ARC on a Navy-sponsored R&D contract is herein described. Also described is the potential backfitting of the UNIMAST Concept to existing ships; e.g., the DDG-993. Battle damage vulnerability of the UNIMAST Concept with respect to a conventional two mast design is addressed. It is argued that the UNIMAST Concept affords no degradation in vulnerability due to improved potential for protecting vital antenna parts.

NAVAL ENGINEERS JOURNAL 1984年第2期96卷 47-58页

作者： DANGEL, R BRICE, AE The Authors A. Edward Brice was born and educated in Scotland where he graduated from the James Watt Memorial College and Paisley Technical College. His earliest marine engineering experience was obtained at Scotts's Shipbuilding and Engineering Company Limited from 1952 to 1959 where he was involved in the production and design of steam and diesel machinery plants for both Naval and commercial ships. During a five year stay in Canada Mr. Brice gained diversified experience in industries other than marine such as petrochemical plants and steel mills. He moved to the U.S. in 1964 where he was the design supervisor in charge of marine engineering at NASSCO covering new construction for American President Lines AFS type ships for the U.S. Navy Project Mohole Car Ferries for the State of Washington and 17 LST's for the U.S. Navy. During the contract definition phase of the DD-963 Mr. Brice authored several portions of the technical proposal while employed by Litton industries. He was also responsible for the system and detail design including the technical management of sub-contracts for the steam propulsion plant for the LHA 1 Class ships. Mr. Brice has been active in the Washington area for the last ten years performing marine engineering projects for the U.S. Navy. His principal interest since 1974 has been in shipboard energy conservation. He assisted in the development of the NavySTMSYS program and later in the operational verification aboard FF-1074. Mr. Brice has conducted four SECA T visits aboard ships with 1200 PSI steam plants and has recently completed an at-sea visit aboard on AOR with a 600 PSI steam plant. Richard Dangel was bom in New York City. He received his Bachelor's degree from the Sloan School of Industrial Management of the Massachusetts Institute of Technology in 1955. He has also completed graduate work for a Masters in Engineering Administration at George Washington University. Since graduation he has spent 11 years in private industry with companies in the DOD engineering research

The Ship Energy Conservation Assist Team (SECAT) program was initiated in Fiscal Year (FY) 82 by the Naval Sea systems Command (NAVSEA) to demonstrate and introduce individual Ship Commands to known energy conserving techniques without adding equipment complexity or additional maintenance burden. The principal objective is to provide each ship with an energy consumption, coupled with recommended energy conservation strategies. The technique involves both in-port and underway monitoring and introduction of energy efficient machinery plant alignments, fuel consumption curve generation, and most efficient speed curves. The program has completed visits on six combatants and enjoys the support of both the Commander, Naval Surface Forces, U.S. Atlantic Fleet (COMNAVSURFLANT) and the Commander-in-Chief, U.S. Atlantic Fleet (CINCLANT). Plans are to perform SECAT on additional DDG 2 and FF 1052/1078 Class ships and initiate SECAT on additional ship types in FY 83.
