Pandemic outbreaks of H1N1 infections are frequently reported around the world. Despite the availability of influenza remedies, the high tendency for influenza virus to mutate can lead to the emergence of drug-resistant strains. Additionally, the adverse effects of current anti-flu drugs that can occur for some patients, such as potential psychiatric problems caused by oseltamivir, have led some countries to implement restrictions on the use of these drugs. In response to the urgent demand to explore and design novel antivirals, we have developed potent anti-flu materials derived from alginate (Alg) of seaweeds. Preparation involves a mixture of sodium alginate with ammonia sulfite (AS) in a one-step pyrolytic reaction, which forms carbonized nanogels (CNGs). We have characterized the chemical and physical properties of these Alg@AS CNGs, validated the anti-flu activity in vitro and in vivo, and explored the underlying mechanisms that Alg@AS CNGs could exert. Our results indicate that the Alg@AS CNGs have abundant sulfite/sulfate surface moieties, and that they have high biocompatibility and remarkable viral suppression properties against H1N1. The viral suppression of Alg@AS CNGs was shown to be superior to other sulfated polysaccharides, such as fucoidan, carrageenan, and chondroitin sulfate. The administration of Alg@AS CNGs to H1N1-infected cells and mice resulted in higher cellular viabilities and mouse survival rates, respectively. Improved pathological indices were observed in lung sections, which showed substantially reduced gene expression of inflammatory mediators in tissues upon Alg@AS CNG treatment. We further showed that the Alg@AS CNGs could inhibit H1N1 infection by binding to viral particles and lowering the oxidative stress in cells. © 2022, The Authors. All rights reserved.

作者： Tseng, Wan-Ling Lin, Cheng-Wei Wang, Yi-Chi Hsu, Huang-Hsiung Chiu, Kuan-Ming Wu, Yueh-Shyuan Hsieh, Yi-Huan Chen, Ying-Ting Ocean Center National Taiwan University Taipei Taiwan Research Center for Environmental Changes Academia Sinica Taipei Taiwan Swedish Meteorological and Hydrological Institute Sweden Department of Energy Engineering Nation United University Taiwan Green Energy and Environment Research Laboratories Industrial Technology Research Institute Taipei Hsinchu Taiwan Office of Sustainability National Taiwan University Taipei Taiwan International Degree Program in Climate Change and Sustainable Development National Taiwan University Taipei Taiwan

The transition to renewable energy sources, such as offshore wind farms, is essential in mitigating climate change. Taiwan has set ambitious targets to harness wind energy from the Taiwan Strait, but offshore wind farm installations are highly dependent on weather conditions, particularly wind speeds. This study examines the relationship between the El Niño-Southern Oscillation (ENSO) and offshore wind farm installation by assessing weather windows—periods with wind speeds below 12 m per second at a height of 100 m for at least 12 h. Our analysis shows that during La Niña years, the number of feasible weather windows decreases by up to 40 %, particularly between October and June, compared to neutral and El Niño years. This decrease can be as high as fourfold in December, significantly impacting installation schedules. Seasonal variations are also notable, with wind speeds exceeding 12 m s⁻¹ in winter 66.4 % of the time, compared to 29.4 % in spring, making spring and summer the most favorable periods for installation. However, even during these favorable seasons, La Niña years can bring higher wind speeds, necessitating careful planning. These results underscore the importance of integrating ENSO forecasts into project planning to avoid installation delays and optimize installation timelines. By leveraging seasonal and interannual climate variability predictions, decision-makers can improve the resilience of offshore wind farm projects and ensure efficient energy transition strategies. © 2024

The SA'AR-5 Corvette program is the first major warship construction to be entirely accomplished using a 3-dimensional, interference checked computer based design. This paper discusses the organization and approach used to create the design models which form the basis for interference checking as well as the source of extracted production data. The design or product model is the nucleus of the computer data base that defines the configuration of the entire ship. The data base includes geometry, weight, and material, as well as production control data. The ability of the computer to link such diverse information is the key to maintaining configuration control during the course of the design and construction. The ease with which formatted manufacturing data (both N.C. fabrication and installation) can be extracted enables the preparation of detailed packages containing the desired geometry as well as the associated material and sequencing data, thus assuring the producibility of the design. The SA'AR-5 design is CAD/CAM's state of the art in U.S. shipbuilding.

A research group at the Massachusetts Institute of technology has completed the first phase of the development of a computer assisted model for analyzing complex decisions and policies regarding oil spill cleanup. The model is the product of an ongoing MIT Sea Grant project, sponsored by a consortium of government and industry organizations, including the National oceanic and Atmospheric Administration, the U.S. C oast G uard , the U.S. N avy , the Commonwealth of Massachusetts, the Spill Control Association of America, JFB Scientific Corporation, the Doherty Foundation, Petro-Canada and Texaco. The model can be used, among other things, in strategic planning for the long-term oil spill response needs of a region, in assisting On Scene Coordinators in responding to a specific spill (tactical/operational setting), in evaluating the environmental and economic damages of a spill versus the cost of cleanup, in simulation and training, and in the analysis of various policy and regulatory issues such as the effects of delays, the use of dispersants and the investigation of liability and compensation issues. The paper describes the model in detail, focuses on its potential uses and presents experience with its application in conjunction with pollution control efforts of the U.S. Navy. Specifically, we outline the application of the model in the Port of Charleston, South Carolina, an ongoing project sponsored by the Naval Facilities engineering Command. The difficulty of gathering data for such an application is discussed.

NAVAL ENGINEERS JOURNAL 1982年第6期94卷 63-71页

作者： LIBERATORE, DJ BASKERVILLE, JE LCdr. Donald J. Liberatore USN: began his career in the U.S. Navy in 1965. He has had many diverse assignments involving surface ships and submarines during the past seventeen years. During his tour at Naval Shipyard Portsmouth (N.H.) he was Assistant Design Superintendent and responsible for the introduction of Heat Recoverable Coupling technology into the shipyard. Presently he is assigned to the Naval Sea Systems Command (NAVSEA) in the Sonar Dome Office. Prior assignments within NAVSEA have been as Assistant Ship Systems Design Manager for the SSNX and FA-SSN preliminary designs in the Submarine Propulsion Analysis Branch in the Submarine Hydrodynamics Branch and in the Gear Coupling and Clutch Branch. He received his Bachelor of Engineering degree from Vanderbilt University in 1971 and in 1977 graduated from Massachusetts Institute of Technology with his M.S. degree in Naval Architecture and Marine Engineering and his Professional degree of Ocean Engineer. A member of ASNE since 1975 LCdr. Liberatore also is a member of IEEE SNAME the Naval Institute and Sigma Xi. Cdr. James E. Baskerville USN: is presently assigned to NAVSEA as the Ship Manager for the DDG 51 the Navy's next generation surface combatant.

Although Heat Recoverable Couplings (HRCs), used to join pipe, may be labeled innovative “state-of-the-art” technology for U.S. Naval Shipyards, they have been in use in foreign ships and high technology industries for over a decade. HRCs provide a permanent leak-proof pipe joint in specified applications without the use of high temperature and the inherent hazards of an open flame. Manufactured from NITINOL, a nickel-titanium alloy developed by the U.S. Navy, the couplings exhibit a “shape memory” characteristic. That is, they return (shrink) to a specified shape (pipe diameter) thus forming a mechanical seal when the expanded coupling is removed from a cryogenic environment and warmed above approximately —130°C. This paper provides background information into the development of NITINOL, technical explanation of shape memory metallurgy, and a summary of results, with specific examples, describing the trial use of HRCs at Pearl Harbor and Norfolk Naval Shipyards. Limited return cost data and recommendations for future use are presented. Then, using the HRC program as a basis, the Authors discuss the conservative nature of the ship repair and maintenance environment. This environment, in the Authors' opinion, couples with complex contractual constraints and requirements which serve to restrict the introduction of new ideas. An analogy is made to Russian tenacity of recent years which promotes “exploring and doing” while we in the U.S. Navy are frequently content to study.

While most of the theater ballistic missiles (TBM) in threat countries' inventories are of the shorter range SCUD varieties, mid- to long-range versions are currently in development in a number of third world countries. Threat potential exists in the following three battle spaces: endo-atmosphere (0-30 km), high endo-atmosphere (30-70 km) and exo-atmosphere (greater than 70 km). The inherent short range and low speed of endo-atmospheric threats match well with capabilities of SM-2 Block IVA, which equips the Navy with an area defense capability The exo-atmospheric TBMs are longer range and can threaten more targets which may be widely dispersed. Their higher velocities reduce response times dramatically Therefore, exo-atmospheric TBMs create the need for Standard Missile-3 (SM-3), which provides the Navy with theater wide defense capability. Defining its area and theater wide systems as clearly endo-atmospheric and exo-atmospheric systems allows the Navy to use derivatives of the Standard Missile Block IV to take full advantage of the conditions associated with each of these operating zones. Use of an existing missile and ship system baseline also allows use of the existing interface structure to minimize cost. To counter the endo-atmospheric TBMs, the SM-2 BLK TVA upgrades include an advanced imaging infrared (IIR) seeker, an improved fast-reaction auto pilot and a forward looking RE all in the same volume as the existing missile. The highly responsive SM-2 Block IVA missile, complemented with Aegis weapons systems modifications, provides capability against enemy aircraft and cruise missiles, as well as TBMs. Standard Missile-3 (SM-3) replaces the SM-2 Block TV warhead, radar and guidance section with a boosted third stage and an advanced kinetic warhead (KW). Operation in the exo-atmospheric region permits a KW design with autonomous guidance control and divert thrusters for high maneuverability and has the capability of achieving very high interceptor velocities.

Taylor Naval Ship Research and Development Center in 1957 as a co-operative student/trainee and received his Bachelor of Science Degree in Physics from Virginia Polytechnic Institute. As a 32-year-old naval architect in 1971 he received both the VietnamHonorServiceMedaland the Navy'sMeritoriousCivilianServiceAwardfor his eight months as liaison with the Vietnamese NAVVS ferro-cement ship program. As head of the Seakeeping and Stabilization Group of the Surface Ship Dynamics Branch his work has led to the development of a new standard Ship Motion Computer Program and the application of ship motions to ship habitability operability and survivability problems. A major area of this work has been the ship/aircraft interface which is particularly sensitive to ship motions wind and other environmental factors. Mr. Dennis A. Woolaver:has been employed as a Naval Architect at the David W. Taylor Naval Ship Research and Development Center since 1965 where his work has resulted in numerous patents.

The potential use of rudders as anti-roll devices has long been recognized. However, the possible interference of this secondary function of the rudder with its primary role as the steering mechanism has prevented, for many years, the development of practical rudder roll stabilizers. The practical feasibility of rudder roll stabilization has, however, in recent years been demonstrated by two systems designed and developed for operational evaluation aboard two different U.S. C oast G uard Cutters, i.e., Jarvis and Mellon of the 3,000-ton, 378-foot HAMILTON Class. The authors describe the major components of the rudder roll stabilization (RRS) system, along with the design goals and methodology as applied to these first two prototypes. In addition, a brief history of the hardware development is provided in order to show some of the lessons learned. The near flawless performance of the prototypes over the past four years of operational use in the North Pacific is documented. Results from various sea trials and reports of the ship operators are cited and discussed. The paper concludes with a discussion of the costs and benefits of roll stabilization achieved using both a modern anti-roll fin system, as well as two different performance level RRS systems. The benefits of roll stabilization are demonstrated by the relative expansion in the operational envelopes of the USS OLIVER HAZARD PERRY (FFG-7) Class. The varying levels of roll stabilization suggest that the merits of fins and RRS systems are strongly dependent on mission requirements and the environment. The demonstrated performance of the reliable RRS system offers the naval ship acquisition manager a good economical stabilization system.

He has over 19 years of experience in ship structure research and light weight metallic development for U.S. Navy fleet applications. He received a B.S. in civil engineering from Long Island University and a M.S. in ocean engineering from Stevens Institute of Technology.

Since the early 1980s, the U.S. Navy, in conjunction with industry, has continued to develop and test innovative lightweight structural concepts with the purpose of seeking alternative replacements for conventional plate beam metallic structures. One commercially available concept currently under investigation is lightweight metallic corrugated core sandwich panels. This paper presents both elastic and plastic design methods for lightweight metallic corrugated core sandwich panels subjected to air blast loading. The equations presented in this paper, while not a complete solution to the complicated dynamic, elastic plastic phenomena of blast wave-rigid body interaction, are offered as a set of relatively simple analytical expressions that can be used in preliminary design. Because of the closed form nature of the equations the designer has the capability to quickly identify the most important parameters effecting the response of lightweight metallic corrugated core sandwich panels to air blast loads.
