    Full Text Available The fuzziness and randomness is integrated by using digital characteristics, such as Expected value, Entropy and Hyper entropy. The cloud model adapted to reliability evaluation is put forward based on the concept of the surface to air missile weapon. The cloud scale of the qualitative evaluation is constructed, and the quantitative variable and the qualitative variable in the system reliability evaluation are corresponded. The practical calculation result shows that it is more effective to analyze the reliability of the surface to air missile weapon by this way. The practical calculation result also reflects the model expressed by cloud theory is more consistent with the human thinking style of uncertainty.

    1988-12-01

    Evaluation of 86 employees with a history of leukopenia at the Naval Weapons Center (NWC), China Lake, California, was done by exposure questionnaires, medical histories, physical examinations, peripheral blood smear, and bone marrow evaluations, including morphologic examination, stem cell culture, and cytogenetics. Forty-eight subjects were found to be leukopenic at the time of the study, and two subjects were found to have hairy cell leukemia. All subjects had positive exposure histories and were healthy at the time of the study. Review of peripheral smears identified the patients with marrow abnormalities. Bone marrow cultures revealed several patients with possible marrow suppression. Chromosome studies were not diagnostic. Five-year follow-up health questionnaires revealed no significant health problems; the two workers with hairy cell leukemia are alive and fully functional. Leukopenia in itself does not appear to be a risk factor for poor health, and it is unknown whether or not it may be a useful screening tool to identify workers at risk in toxic environments. Careful evaluation of blood cell counts and peripheral smears should be sufficient to identify people with potential marrow abnormalities.

    We propose to develop a national center of excellence in Regolith Radiative Transfer (RRT), i.e., in modeling spectral reflectivity and emissivity of grainy or structured surfaces. The focus is the regime where the structural elements of grainy surfaces have grain sizes and separations of tens of microns, comparable to the wavelengths carrying diagnostic compositional information. This regime is of fundamental interest to remote sensing of planetary and terrestrial surfaces.

    A survey of environmental surfaces in two Atlanta area day care centers was conducted to determine the prevalence of fecal coliform bacteria, considered a marker for the presence of fecal contamination which might contain pathogenic parasites, bacteria, or viruses. Fecal coliforms were found in 17 (4.3%) of 398 representative samples of building surfaces, furniture, and other objects. These surfaces may be involved in the chain of transmission of enteric diseases among children. Therefore, disinfection of inanimate objects, in addition to good handwashing, may be important in controlling the spread of enteric diseases in day care centers. PMID:6830225

    The authors take issue with the assessment that the advent of antisatellite weapons implies that the beneficial role of satellites in arms control, confidence building, and conflict resolution has been judged less important than their ability to support actual military operations. They argue that there is still an opportunity to negotiate a militarily significant and verifiable constraint on the growth of antisatellite technology that would be in the security interest of the US and the world as a whole. They base their opinion on an assessment of the roles of the existing military satellites and their vulnerability to antisatellite weapons and the probable impact of antisatellite weapons on various kinds of crisis and conflict. 10 figures, 1 table

    Present day air-delivered weapons are of a closed architecture, with little to no ability to tailor the weapon for the individual engagement. The closed architectures require weaponeers to make the target fit the weapon instead of fitting the individual weapons to a target. The concept of a flexible weapons aims to modularize weapons design using an open architecture shell into which different modules are inserted to achieve the desired target fractional damage while reducing cost and civilian casualties. This thesis shows that the architecture design factors of damage mechanism, fusing, weapons weight, guidance, and propulsion are significant in enhancing weapon performance objectives, and would benefit from modularization. Additionally, this thesis constructs an algorithm that can be used to design a weapon set for a particular target class based on these modular components.

  20. Nuclear weapons modernizations

    Kristensen, Hans M. [Federation of American Scientists, Washington, DC (United States)

    2014-05-09

    This article reviews the nuclear weapons modernization programs underway in the world's nine nuclear weapons states. It concludes that despite significant reductions in overall weapons inventories since the end of the Cold War, the pace of reductions is slowing - four of the nuclear weapons states are even increasing their arsenals, and all the nuclear weapons states are busy modernizing their remaining arsenals in what appears to be a dynamic and counterproductive nuclear competition. The author questions whether perpetual modernization combined with no specific plan for the elimination of nuclear weapons is consistent with the nuclear Non-Proliferation Treaty and concludes that new limits on nuclear modernizations are needed.

    In some societies, weapons are plentiful and highly visible. This review examines recent trends in research on the weapons effect, which is the finding that the mere presence of weapons can prime people to behave aggressively. The General Aggression Model provides a theoretical framework to explain why the weapons effect occurs. This model postulates that exposure to weapons increases aggressive thoughts and hostile appraisals, thus explaining why weapons facilitate aggressive behavior. Data from meta-analytic reviews are consistent with the General Aggression Model. These findings have important practical as well as theoretical implications. They suggest that the link between weapons and aggression is very strong in semantic memory, and that merely seeing a weapon can make people more aggressive. Copyright © 2017 Elsevier Ltd.

    Effects of artificial pinning centers (APCs) into ErBa 2 Cu 3 O 7-δ films are discussed. The APCs used in this paper is BaZrO 3 and Zn which are mixed into ErBa 2 Cu 3 O 7-δ ceramic targets. The targets with various contents of APCs are ablated and films are grown on substrates with the APCs. X-ray diffraction patterns show there are no other phases than ErBa 2 Cu 3 O 7-δ and APCs. Transmission electron microscopy (TEM) shows the BaZrO 3 APSs grow along the c-axis of the films. The introduction of APCs decreases surface resistance (R S ) of ErBa 2 Cu 3 O 7-δ films and increases critical current density (J C ) of the films. R S measurements revealed that the ErBa 2 Cu 3 O 7-δ films with APCs showed a lower R S than that of the ErBa 2 Cu 3 O 7-δ films without APCs

  7. Rays as weapons

    Vogel, H.

    2007-01-01

    Purpose: Ionizing radiation is being regarded as life threatening. Therefore, accidents in nuclear power plants are considered equal threatening as nuclear bomb explosions, and attacks with dirty bombs are thought as dangerous as nuclear weapon explosions. However, there are differences between a nuclear bomb explosion, the largest imaginable accident in a nuclear power plant, and an attack with a dirty bomb. It is intended to point them out. Method: The processes are described, which damage in a nuclear bomb explosion, in the largest imaginable accident in a nuclear power plant, and in an attack with a dirty bomb. Their effects are compared with each other, i.e. explosion, heat, shock wave (blast), ionizing radiation, and fallout. Results: In the center of the explosion of a nuclear bomb, the temperature rises to 100 Mio deg.C, this induces damaging heat radiation and shock wave. In the largest imaginable accident in a nuclear power plant and in the conventional explosion of a dirty bomb, the temperature may rise up to 3000 deg. C, heat radiation and blast are limited to a short distance. In nuclear power plants, explosions due to oxyhydrogen gas or steam may occur. In nuclear explosions the dispersed radioactive material (fall out) consists mainly of isotopes with short half-life, in nuclear power plants and in dirty bomb attacks with longer half-life. The amount of fall out is comparable in nuclear bomb explosions with that in the largest imaginable accident in a nuclear power plant, it is smaller in attacks with dirty bombs. An explosion in a nuclear power plant even in the largest imaginable accident is not a nuclear explosion. In Hiroshima and Nagasaki, there were 200,000 victims nearly all by heat and blast, some 300 died by ionizing radiation. In Chernobyl, there have been less than 100 victims due to ionizing radiation up till now. A dirty bomb kills possibly with the explosion of conventional explosive, the dispersed radioactive material may damage

    A method and apparatus for non-invasively indentifying different types of nuclear weapons is disclosed. A neutron generator is placed against the weapon to generate a stream of neutrons causing fissioning within the weapon. A first detects the generation of the neutrons and produces a signal indicative thereof. A second particle detector located on the opposite side of the weapon detects the fission particles and produces signals indicative thereof. The signals are converted into a detected pattern and a computer compares the detected pattern with known patterns of weapons and indicates which known weapon has a substantially similar pattern. Either a time distribution pattern or noise analysis pattern, or both, is used. Gamma-neutron discrimination and a third particle detector for fission particles adjacent the second particle detector are preferably used. The neutrons are generated by either a decay neutron source or a pulled neutron particle accelerator.

    International Nuclear Information System (INIS)

    Karp, R.C.

    1991-01-01

    Recent improvements in East-West relations and the process of dramatic political change in Europe may result in unprecedented opportunities to reduce the global arsenal of nuclear weapons. Despite these welcome developments, the prospects for effectively controlling the spread of nuclear capability in the Third World have remained much less encouraging. The possibility of large reductions in nuclear weapons poses fundamental questions about their purpose. Why have some states chosen to acquire nuclear weapons? How and why have these decisions been maintained over time? Why have some states elected to approach, but not cross, the nuclear threshold? This book examines the commonalities and differences in political approaches to nuclear weapons both within and between three groups of states: nuclear, non-nuclear and threshold. The chapters explore the evolution of thinking about nuclear weapons and the role these weapons play in national security planning, and question the official security rationales offered by the nuclear weapon states for the maintenance of nuclear capabilities. For the non-nuclear weapon states, the book presents an analysis of alternative ways of assuring security and foreign policy effectiveness. For the threshold states, it examines the regional contexts within which these states maintain their threshold status. This book transcends traditional East-West approaches to analysis of nuclear issues by giving equal prominence to the issues of nuclear proliferation and non-nuclearism. The book also provides a comprehensive analysis of how current approaches to nuclear weapons have evolved both within and among the groups of countries under study

    Silicon vacancy (SiV) centers in diamonds have emerged as a very promising candidate for quantum emitters due to their narrow emission line resulting in their indistinguishability. While many different quantum emitters have already been used for the excitation of various propagating plasmonic modes......, the corresponding exploitation of SiV centers has remained so far uncharted territory. Here, we report on the excitation of surface plasmon modes supported by silver nanowires using SiV centers in nanodiamonds. The coupling of SiV center fluorescence to surface plasmons is observed, when a nanodiamond situated...

  17. Nuclear weapons free zones

    Stahl, K.

    1990-01-01

    The article analyses the concept and problems of the two nuclear weapons free zones in Latin America and in the South Pacific established by the Treaty of Tlatelolco and the Treaty of Rarotonga. So far the nuclear weapons states except China have refused to sign the additional protocols of the Treaties or have signed them only with considerable provisos. Therefore they don't fully recognize the nuclear weapons free status of those zones, or they don't recognize it at all. Both Treaties contain no provisions to regulate the transit of nuclear weapons through the zones. This allows de facto the stationing of nuclear weapons in the military bases of the US which are located within the nuclear weapons free zone of Latin America. The Treaty of Tlatelolco contains also the right of the states, party to the Treaty, to explode nuclear devices for peaceful purposes. Since peaceful and military nuclear explosions cannot be distinguished technically, this right could also undermine the nuclear weapons free status of the region. Important nuclear threshold countries like Argentina and Brazil have furthermore refrained from putting the Treaty into force. (orig.) [de

    Nanoscale quantum probes such as the nitrogen-vacancy (NV) center in diamonds have demonstrated remarkable sensing capabilities over the past decade as control over fabrication and manipulation of these systems has evolved. The biocompatibility and rich surface chemistry of diamonds has added to the utility of these probes but, as the size of these nanoscale systems is reduced, the surface chemistry of diamond begins to impact the quantum properties of the NV center. In this work, we systematically study the effect of the diamond surface chemistry on the quantum coherence of the NV center in nanodiamonds (NDs) 50 nm in size. Our results show that a borane-reduced diamond surface can on average double the spin relaxation time of individual NV centers in nanodiamonds when compared to thermally oxidized surfaces. Using a combination of infrared and X-ray absorption spectroscopy techniques, we correlate the changes in quantum relaxation rates with the conversion of sp 2 carbon to C-O and C-H bonds on the diamond surface. These findings implicate double-bonded carbon species as a dominant source of spin noise for near surface NV centers. The link between the surface chemistry and quantum coherence indicates that through tailored engineering of the surface, the quantum properties and magnetic sensitivity of these nanoscale systems may approach that observed in bulk diamond.

    2017-11-01

    Beginning in the 1940's, the United States has pursued the development of hypersonic technologies, enabling atmospheric flight in excess of five times the speed of sound. Hypersonic flight has application to a range of military and civilian applications, including commercial transport, space access, and various weapons and sensing platforms. A number of flight tests of hypersonic vehicles have been conducted by countries around the world, including the United States, Russia, and China, that could lead the way to future hypersonic global strike weapon systems. These weapons would be especially effective at penetrating conventional defenses, and could pose a significant risk to national security.

    Lithium fluoride nanocrystals are irradiated by gamma quanta at 77 K. The radiation color centers formed in a near-surface layer of nanocrystals are studied. Absorption, luminescence and luminescence excitation spectra of the surface defects have been measured. It has been found that the luminescence excitation spectra for aggregated surface centers consist of two or three bands with not very much different intensities. Reactions of the surface centers separately with electrons and with anion vacancies have been investigated. Numbers of anion vacancies and electrons entering into the centers composition have been established and it has been found that F{sub S1}, F{sub S1}{sup −}, F{sub S2}, F{sub S2}{sup −}, F{sub S3}{sup +} and F{sub S3} types of the surface centers are formed. The degree of luminescence polarization has been defined and it has been determined that the polarization degree for F{sub S2}{sup +} centers changes sign under transition from one excitation band to another. It has been shown that during irradiation at 77 K radiation-induced defects are formed more efficiently on the surface than in the bulk. - Highlights: • Radiative color centers were fabricated in lithium fluoride nanocrystals. • The unique absorption and luminescence characteristics are inherent in the centers. • The reactions of these centers with electrons and anion vacancies were studied. • The degree of luminescence polarization was defined. • Numbers of anion vacancies and electrons forming the centers were established.

  4. Virtual nuclear weapons

    Energy Technology Data Exchange (ETDEWEB)

    Pilat, J.F.

    1997-08-01

    The term virtual nuclear weapons proliferation and arsenals, as opposed to actual weapons and arsenals, has entered in recent years the American lexicon of nuclear strategy, arms control, and nonproliferation. While the term seems to have an intuitive appeal, largely due to its cyberspace imagery, its current use is still vague and loose. The author believes, however, that if the term is clearly delineated, it might offer a promising approach to conceptualizing certain current problems of proliferation. The first use is in a reference to an old problem that has resurfaced recently: the problem of growing availability of weapon-usable nuclear materials in civilian nuclear programs along with materials made `excess` to defense needs by current arms reduction and dismantlement. It is argued that the availability of these vast materials, either by declared nuclear-weapon states or by technologically advanced nonweapon states, makes it possible for those states to rapidly assemble and deploy nuclear weapons. The second use has quite a different set of connotations. It is derived conceptually from the imagery of computer-generated reality. In this use, one thinks of virtual proliferation and arsenals not in terms of the physical hardware required to make the bomb but rather in terms of the knowledge/experience required to design, assemble, and deploy the arsenal. Virtual weapons are a physics reality and cannot be ignored in a world where knowledge, experience, materials, and other requirements to make nuclear weapons are widespread, and where dramatic army reductions and, in some cases, disarmament are realities. These concepts are useful in defining a continuum of virtual capabilities, ranging from those at the low end that derive from general technology diffusion and the existence of nuclear energy programs to those at the high end that involve conscious decisions to develop or maintain militarily significant nuclear-weapon capabilities.

    Chemical Weapons are kind of Weapons of Mass Destruction (WMD). They were used large quantities in WWI. Historically, large quantities usage like WWI was not recorded, but small usage has appeared now and then. Chemical weapons are so called "Nuclear weapon for poor countrys" because it's very easy to produce/possession being possible. They are categorized (1) Nerve Agents, (2) Blister Agents, (3) Cyanide (blood) Agents, (4) Pulmonary Agents, (5) Incapacitating Agents (6) Tear Agents from the viewpoint of human body interaction. In 1997 the Chemical Weapons Convention has taken effect. It prohibits chemical weapons development/production, and Organization for the Prohibition of Chemical Weapons (OPCW) verification regime contributes to the chemical weapons disposal. But possibility of possession/use of weapons of mass destruction by terrorist group represented in one by Matsumoto and Tokyo Subway Sarin Attack, So new chemical terrorism countermeasures are necessary.

    The memoirs of the author traces his life from his first-year graduate studies in physics at the University of Rochester in 1942 to his present position as Director of the University of California's Institute on Global Conflict and Cooperation. The part of his life involved in making weapons extends from 1942 to 1961. During this period, he worked with E.O. Lawrence on the Manhattan Project and served as director of Livermore after it became the Atomic Energy Commission's second nuclear weapons laboratory. He also served on many government advisory boards and commissions dealing with nuclear and other weapons. In 1961, the combination of a heart attack and changes in administration in Washington led York too return to the University of California for the talking peace portion of his life. He has since become a public exponent of arms control and disarmament and the futility of seeking increased security through more and better nuclear weapons. York's explanation of his move from making weapons to talking peace leaves the reader with a puzzle

    Purpose: X-ray findings are described, which are typical for injuries due to conventional weapons. It is intended to demonstrate that radiographs can show findings characteristic for weapons. Material and method: The radiograms have been collected in Vietnam, Croatia, Serbia, Bosnia, Chad, Iran, Afghanistan, USA, Great Britain, France, Israel, Palestine, and Germany. Results: Radiograms of injuries due to hand grenades show their content (globes) and cover fragments. The globes are localized regionally in the victim's body. Survivors of cluster bombs show singular or few globes; having been hit by many globes would have been lethal. Shotguns produce characteristic distributions of the pallets and depth of penetration different from those of hand grenades and cluster bombs; cover fragments are lacking. Gunshot wounds (GSW) can be differentiated in those to low velocity bullets, high velocity projectiles, and projectiles, which disintegrate on impact. The radiogram furnishes the information about a dangerous shock and helps to recognize the weapon. Radiograms of victims of explosion show fragments and injuries due to the blast, information valid for therapy planning and prognosis. The radiogram shows details which can be used in therapy, forensic medicine and in war propaganda - examples could be findings typical for cluster bombs and for dumdum bullets; it shows the cruelty of the employment of weapons against humans and the conflict between the goal of medical care and those of military actions. Conclusion: Radiographs may show, which weapon has been employed; they can be read as war reports.

    Anderson, Peter D

    2012-04-01

    The potential for biological weapons to be used in terrorism is a real possibility. Biological weapons include infectious agents and toxins. Toxins are poisons produced by living organisms. Toxins relevant to bioterrorism include ricin, botulinum, Clostridium perfrigens epsilson toxin, conotoxins, shigatoxins, saxitoxins, tetrodotoxins, mycotoxins, and nicotine. Toxins have properties of biological and chemical weapons. Unlike pathogens, toxins do not produce an infection. Ricin causes multiorgan toxicity by blocking protein synthesis. Botulinum blocks acetylcholine in the peripheral nervous system leading to muscle paralysis. Epsilon toxin damages cell membranes. Conotoxins block potassium and sodium channels in neurons. Shigatoxins inhibit protein synthesis and induce apoptosis. Saxitoxin and tetrodotoxin inhibit sodium channels in neurons. Mycotoxins include aflatoxins and trichothecenes. Aflatoxins are carcinogens. Trichothecenes inhibit protein and nucleic acid synthesis. Nicotine produces numerous nicotinic effects in the nervous system.

    Dyson, F.

    1984-01-01

    The British-born physicist presents a full-blown critique of US weapons policy. His careful evaluation of opposing views leads him to endorse a live-and-let-live concept of arms control, which would reject both assured destruction and first use of nuclear weapons in favor of abolishing them. Dyson's faith in the humane progress of military technology and his tolerance of dangerous conventional weapons will not please dovish readers, while his denunciation of military idolatry and his support of a nuclear freeze will disappoint some hawks. Along with moving personal memories of war and pacifism, the most original sections of the book are the author's insightful comments about the Soviet Union and the issue of verification

    The safe destruction and dismantling of chemical, nuclear and conventional weapons is of fundamental importance to the security of all countries represented in this volume. Expertise in the field is not confined to one country or organisation: all can benefit from each other. There is an ever present danger of proliferation of weapons of mass destruction: approximately two dozen countries have ongoing programmes to develop or acquire such weapons, and many are also gaining the capability to build air-surface delivery systems. But much can be done to prevent proliferation by reducing leakage of materials and know-how and by solving the problems of the destruction of surplus weapons systems, which has now come to be a key issue. In 13 sessions of the workshop attention was paid to (1) Dismantlement and Destruction of Chemical, Nuclear and Conventional Weapons; (2) Status of Implementation of Arms Control Treaties and Voluntary Commitments; (3) National Perspectives on Cooperation in Disarmament; (4) Stocktaking of National and Bilateral Disposal/Destruction Programmes: Chemical Weapons; (5) Stocktaking of National and Bilateral Disposal/Destruction Programmes: Nuclear Weapons; (6) Stocktaking of National and Bilateral Disposal/Destruction Programmes: Conventional Weapons.

    Previously, we demonstrated that children in day care centers commonly experience diarrhea due to rotavirus, giardia, and bacterial pathogens. Multiple agents frequently coexist, and the environment is heavily contaminated with enteric bacteria during outbreaks. A study of environmental surface contamination with rotavirus was performed during three non-outbreak periods. Of 25 samples collected from environmental surfaces and teachers hands at a day care center, 4 (16%) were positive for rotavirus antigen when a fluorescence assay was used. We also examined the survival of two animal viruses, rotavirus SA-11 and poliovirus type 1, and bacteriophage 12 on similar environmental surfaces in a laboratory. Poliovirus type 1 and bacteriophage f2 were more resistant to drying than rotavirus SA-11 and could be recovered after a 90-min exposure on a dry surface. Rotavirus SA-11 could be detected for 30 min. All three viruses survived longer when they were suspended in fecal material than when they were suspended in distilled water. These data suggest that several agents, including rotavirus, can remain viable on contaminated surfaces long enough to be transmitted to susceptible children. This finding helps explain why rotavirus shows a mode of spread like that of parasitic and bacterial agents within day care center settings. PMID:6314896

    Nitrogen-vacancy (NV) centers in diamonds are interesting due to their remarkable characteristics that are well suited to applications in quantum-information processing and magnetic field sensing, as well as representing stable fluorescent sources. Multiple NV centers in nanodiamonds (NDs) are especially useful as biological fluorophores due to their chemical neutrality, brightness and room-temperature photostability. Furthermore, NDs containing multiple NV centers also have potential in high-precision magnetic field and temperature sensing. Coupling NV centers to propagating surface plasmon polariton (SPP) modes gives a base for lab-on-a-chip sensing devices, allows enhanced fluorescence emission and collection which can further enhance the precision of NV-based sensors. Here, we investigate coupling of multiple NV centers in individual NDs to the SPP modes supported by silver surfaces protected by thin dielectric layers and by gold V-grooves (VGs) produced via the self-terminated silicon etching. In the first case, we concentrate on monitoring differences in fluorescence spectra obtained from a source ND, which is illuminated by a pump laser, and from a scattering ND illuminated only by the fluorescence-excited SPP radiation. In the second case, we observe changes in the average NV lifetime when the same ND is characterized outside and inside a VG. Fluorescence emission from the VG terminations is also observed, which confirms the NV coupling to the VG-supported SPP modes. (paper)

    Full Text Available Background: Hippotherapy uses horseback riding movements for therapeutic purposes. In addition to the horse's movement, the choice of equipment and types of floor are also useful in the intervention. The quantification of dynamic parameters that define the interaction of the surface of contact between horse and rider provides insight into how the type of floor surface variations act upon the subject's postural control. Objective: To test whether different types of surfaces promote changes in the amplitude (ACOP and velocity (VCOP of the center of pressure (COP displacement during the rider's contact with the saddle on the horse's back. Method: Twenty two healthy adult male subjects with experience in riding were evaluated. The penetration resistances of asphalt, sand and grass surfaces were measured. The COP data were collected on the three surfaces using a pressure measurement mat. Results: ACOP values were higher in sand, followed by grass and asphalt, with significant differences between sand and asphalt (anteroposterior, p=0.042; mediolateral, p=0.019. The ACOP and VCOP values were higher in the anteroposterior than in the mediolateral direction on all surfaces (ACOP, p=0.001; VCOP, p=0.006. The VCOP did not differ between the surfaces. Conclusion: Postural control, measured by the COP displacement, undergoes variations in its amplitude as a result of the type of floor surface. Therefore, these results reinforce the importance of the choice of floor surface when defining the strategy to be used during hippotherapy intervention.

    We present a study of the spin properties of dense layers of near-surface nitrogen-vacancy (NV) centers in diamond created by nitrogen ion implantation. The optically detected magnetic resonance contrast and linewidth, spin coherence time, and spin relaxation time, are measured as a function of implantation energy, dose, annealing temperature, and surface treatment. To track the presence of damage and surface-related spin defects, we perform in situ electron spin resonance spectroscopy through both double electron-electron resonance and cross-relaxation spectroscopy on the NV centers. We find that, for the energy (4 -30 keV) and dose (5 ×1011-1013ions/cm 2 ) ranges considered, the NV spin properties are mainly governed by the dose via residual implantation-induced paramagnetic defects, but that the resulting magnetic sensitivity is essentially independent of both dose and energy. We then show that the magnetic sensitivity is significantly improved by high-temperature annealing at ≥1100 ∘C . Moreover, the spin properties are not significantly affected by oxygen annealing, apart from the spin relaxation time, which is dramatically decreased. Finally, the average NV depth is determined by nuclear magnetic resonance measurements, giving ≈10 -17 nm at 4-6 keV implantation energy. This study sheds light on the optimal conditions to create dense layers of near-surface NV centers for high-sensitivity sensing and imaging applications.

  9. Evolution of Oxygen Deficiency Center on Fused Silica Surface Irradiated by Ultraviolet Laser and Posttreatment

    Directory of Open Access Journals (Sweden)

    Hai-Bing Lü

    2014-01-01

    Full Text Available Evolution of oxygen deficiency centers (ODCs on a fused silica surface irradiated using a 355 nm ultraviolet (UV laser beam in both vacuum and atmospheric conditions was quantitatively studied using photoluminescence and X-ray photoelectron spectroscopy. When the fusedsilica surface was exposed to the UV laser in vacuum, the laser damage threshold was decreased whereas the concentration of the ODCs was increased. For the fuse silica operated under the high power lasers, creation of ODCs on their surface resulted from the UV laser irradiation, and this is more severe in a high vacuum. The laser fluence and/or laser intensity have significant effects on the increase of the ODCs concentration. The ODCs can be effectively repaired using postoxygen plasma treatment and UV laser irradiation in an excessive oxygen environment. Results also demonstrated that the “gain” and “loss” of oxygen at the silica surface is a reversible and dynamic process.

The divergence-lightning relationships and the importance of wind direction are addressed, and the verification is summarized.

  11. The morality of weapons research.

    Science.gov (United States)

    Forge, John

    2004-07-01

    I ask whether weapons research is ever justified. Weapons research is identified as the business of the engineer. It is argued that the engineer has responsibility for the uses to which the tools that he designs can be put, and that responsibility extends to the use of weapons. It is maintained that there are no inherently defensive weapons, and hence there is no such thing as 'defensive' weapons research. The issue then is what responsibilities as a professional the engineer has in regard to such research. An account is given to ground the injunction not to provide the means to harm as a duty for the engineers. This account is not, however, absolutist, and as such it allows justifiable exceptions. The answer to my question is thus not that weapons research is never justified but there must be a strong assurance that the results will only be used as a just means in a just cause.

    Full Text Available Public fitness centers and exercise facilities have been implicated as possible sources for transmitting community-acquired bacterial infections. However, the overall diversity of the bacterial community residing on the surfaces in these indoor environments is still unknown. In this study, we investigated the overall bacterial ecology of selected fitness centers in a metropolitan area (Memphis, TN, USA utilizing culture-independent pyrosequencing of the 16S rRNA genes. Samples were collected from the skin-contact surfaces (e.g., exercise instruments, floor mats, handrails, etc. within fitness centers. Taxonomical composition revealed the abundance of Firmicutes phyla, followed by Proteobacter and Actinobacteria, with a total of 17 bacterial families and 25 bacterial genera. Most of these bacterial genera are of human and environmental origin (including, air, dust, soil, and water. Additionally, we found the presence of some pathogenic or potential pathogenic bacterial genera including Salmonella, Staphylococcus, Klebsiella, and Micrococcus. Staphylococcus was found to be the most prevalent genus. Presence of viable forms of these pathogens elevates risk of exposure of any susceptible individuals. Several factors (including personal hygiene, surface cleaning and disinfection schedules of the facilities may be the reasons for the rich bacterial diversity found in this study. The current finding underscores the need to increase public awareness on the importance of personal hygiene and sanitation for public gym users.

  13. The Effects of Nuclear Weapons. Third edition

    Glasstone, S; Dolan, P J

    1977-01-01

    Since the last edition of ''The Effects of Nuclear Weapons'' in 1962 much new information has become available concerning nuclear weapon effects. This has come in part from the series of atmospheric tests, including several at very high altitudes, conducted in the Pacific Ocean area in 1962. In addition, laboratory studies, theoretical calculations, and computer simulations have provided a better understanding of the various effects. A new chapter has been added on the electromagnetic pulse. The chapter titles are as follows: general principles of nuclear explosions; descriptions of nuclear explosions; air blast phenomena in air and surface bursts; air blast loading; structural damage from air blast; shock effects of surface and subsurface bursts; thermal radiation and its effects; initial nuclear radiation; residual nuclear radiation and fallout; radio and radar effects; the electromagnetic pulse and its effects; and biological effects.

    most important requirements of Military Standards (muzzle velocity, caliber size and shooting accuracy. In studies of barrel wear, there are numerous theories that explain barrel wear as thermal, mechanical and chemical effects of the projectile and propellant gas on the inner tube surface. It was found that barrel wear is a result of simultaneous effects of all factors mutually linked and very complex, so that, theoretically speaking, they cannot be uniformly determined. The extent of effects of particular factors in the wear process depends on the type of weapon systems and exploitation conditions (mode of fire, intensity and mode of barrel cooling, maintenance, storage conditions, etc.. It is considered that, for small arms, the main factor of wear is the effect of projectiles on the barrel while for artillery weapon barrels it is the erosive effect of powder gases. A life-death barrel which is determined by "ballistic death," is not necessary to be discarded, ie reparation can be done by "new calibration". The procedure of barrel reparation is economically acceptable and gives the possibility of extension of working lifetime and modification of the gun barrel. METHODS OF BARREL LIFE-TIME CALCULATION The conditions for calculating the gun barrel lifetime are described. Since the barrel lifetime depends primarily on the exploitation regime, the usage procedure (shooting program in the military terminology Is prescribed for each individual weapon in particular. The lifetime empirical calculation methods discussed here comprise the methods of French and Russian scientists, i.e.Justrov, Linte, Gabo and Orlov. They are mainly based on empirical constants and elements of the barrel, bullet, projectile velocity and mode of fire. These methods are only partially reliable and cannot predict with certainty the barrel lifetime, - for example, some expressions state that lifetime increases with the increase in initial velocity and barrel caliber, which is incorrect and contrary

    We investigated the influence of spins on surface of nanodiamonds (NDs) to the longitudinal relaxation time (T{sub 1}) and transverse relaxation time (T{sub 2}) of nitrogen vacancy (NV) centers in ND. A spherical model of the NDs was suggested to account for the experimental results of T{sub 1} and T{sub 2}, and the density of surface spins was roughly estimated based on the statistical analysis of experimental results of 72 NDs containing a single NV center. For NDs studied here, the T{sub 1} of NV center inside is highly dependent to the surface spins of the NDs. However, for the T{sub 2} of NV center, intrinsic contributions must be much pronounced than that by surface spins. In other words, T{sub 1} of an NV center in NDs is more sensitive to the change of the surface spin density than T{sub 2}.

    Full Text Available Autonomous weapons would have the capacity to select and attack targets without direct human input. One important objection to the introduction of such weapons is that they will make it more difficult to identify and hold accountable those responsible for undesirable outcomes such as mission failures and civilian casualties. I hypothesize that individuals can modify their attribution of responsibility in predicable ways to accommodate this new technology. The results of a survey experiment are consistent with this; subjects continue to find responsible and hold accountable political and military leaders when autonomous weapons are used, but also attribute responsibility to the designers and programmers of such weapons.

    Diamonds are widely used for jewelry owing to their superior optical properties accounting for their fascinating beauty. Beyond the sparkle, diamond is highly investigated in materials science for its remarkable properties. Recently, fluorescent defects in diamond, particularly the negatively charged nitrogen-vacancy (NV(-)) center, have gained much attention: The NV(-) center emits stable, nonbleaching fluorescence, and thus could be utilized in biolabeling, as a light source, or as a Förster resonance energy transfer donor. Even more remarkable are its spin properties: with the fluorescence intensity of the NV(-) center reacting to the presence of small magnetic fields, it can be utilized as a sensor for magnetic fields as small as the field of a single electron spin. However, a reproducible defect and surface and defect chemistry are crucial to all applications. In this article we review methods for using nanodiamonds for different imaging purposes. The article covers (1) dispersion of particles, (2) surface cleaning, (3) particle size selection and reduction, (4) defect properties, and (5) functionalization and attachment to nanostructures, e.g., scanning probe microscopy tips.

    This study documented background chemical composition of soils, groundwater, surface; water, and sediments of Kennedy Space Center. Two hundred soil samples were collected, 20 each in 10 soil classes. Fifty-one groundwater wells were installed in 4 subaquifers of the Surficial Aquifer and sampled; there were 24 shallow, 16 intermediate, and 11 deep wells. Forty surface water and sediment samples were collected in major watershed basins. All samples were away from sites of known contamination. Samples were analyzed for organochlorine pesticides, aroclors, chlorinated herbicides, polycyclic aromatic hydrocarbons (PAH), total metals, and other parameters. All aroclors (6) were below detection in all media. Some organochlorine pesticides were detected at very low frequencies in soil, sediment, and surface water. Chlorinated herbicides were detected at very low frequencies in soil and sediments. PAH occurred in low frequencies in soiL, shallow groundwater, surface water, and sediments. Concentrations of some metals differed among soil classes, with subaquifers and depths, and among watershed basins for surface water but not sediments. Most of the variation in metal concentrations was natural, but agriculture had increased Cr, Cu, Mn, and Zn.

The proposals arise from a full review carried out in 1989 and include points raised by the Select Committee on the Trident programme. Studies of productivity, pay and conditions, information systems and long term manufacturing strategy have been started to enable recommendations of the reorganisation of the establishments to be made. The details of the Bill were debated for just over two hours. The debate is reported verbatim. The main issues were over the principle of contractorisation, possible staff redundancies, conditions of employment, safety and security. The proposal that the Bill be read a second time was carried.

  11. Verification of Chemical Weapons Destruction

    International Nuclear Information System (INIS)

    Lodding, J.

    2010-01-01

    The Chemical Weapons Convention is the only multilateral treaty that bans completely an entire category of weapons of mass destruction under international verification arrangements. Possessor States, i.e. those that have chemical weapons stockpiles at the time of becoming party to the CWC, commit to destroying these. All States undertake never to acquire chemical weapons and not to help other States acquire such weapons. The CWC foresees time-bound chemical disarmament. The deadlines for destruction for early entrants to the CWC are provided in the treaty. For late entrants, the Conference of States Parties intervenes to set destruction deadlines. One of the unique features of the CWC is thus the regime for verifying destruction of chemical weapons. But how can you design a system for verification at military sites, while protecting military restricted information? What degree of assurance is considered sufficient in such circumstances? How do you divide the verification costs? How do you deal with production capability and initial declarations of existing stockpiles? The founders of the CWC had to address these and other challenges in designing the treaty. Further refinement of the verification system has followed since the treaty opened for signature in 1993 and since inspection work was initiated following entry-into-force of the treaty in 1997. Most of this work concerns destruction at the two large possessor States, Russia and the United States. Perhaps some of the lessons learned from the OPCW experience may be instructive in a future verification regime for nuclear weapons. (author)

    Full Text Available Oil (called by some black gold has not always been as coveted and used, but only in the last hundred years has established itself as a highly sought after as an indispensable proper functioning of modern economic activity that an important factor in international politics. International oil regime has changed in the last decades. In 1960, oil regime was a private oligopol which had links with governments main consuming countries. By then the price of a barrel of oil was two U.S. dollars and seven major transnational oil companies decided the amount of oil that will be produced. Meanwhile the world region with the largest oil exports were more strongly expressed nationalism and decolonization. Result, it was so in the late 60s in the region occur independent states. They have created an organization aim of this resource to their advantage - OPEC (Organization of Petroleum Exporting Countries. Thus since 1973 there have been changes in the international regime governing oil field, namely producing countries were fixed production rate and price. After this time the oil weapon has become increasingly important in the management of international relations. Oil influenced the great powers to Middle East conflicts that occurred in the last century, but their attitude about the emergence of new sources of oil outside OPEC. In the late 90's, Russia has become a major supplier of oil to the West.

    Calvez, Jean-Yves

    2005-01-01

    Written after the 2005 NPT review conference, this article first recalls the early stages of nuclear proliferation: acquisition of nuclear weapons by Great-Britain, USSR, France and China, and creation of the NPT in 1970. The author briefly evokes some weaknesses and violations of this treaty: emergence of new nuclear powers (India, Pakistan, Israel) and of nuclear weapon programmes (Iran, North Korea). He outlines the lack of true rules to impede countries to develop nuclear weapons, and then states that the only solution seems to be a simple abolition of these weapons. This option is notably supported by the Catholic Church as outlined and recalled here. The author discusses the situation of this abolition option, and notices that, even though NPT members committed themselves on this way, some also decided to develop new and smaller weapons. Then, it becomes always more difficult to persuade countries not to possess these weapons. The author finally discusses the issues of terrorism threat in relationship to the miniaturisation process, and regrets the lack of commitment in an abolition process

    Using infrared (IR) spectroscopy and density functional theory (DFT) calculations, interaction of CO with the strongest known pure Brønsted carborane superacids, H(CHB11Hal11) (Hal = F, Cl), was studied. CO readily interacted at room temperature with H(CHB11F11) acid, forming a mixture of bulk salts of formyl and isoformyl cations, which were in equilibrium An(-)H(+)CO COH(+)An(-). The bonding of CO to the surface Brønsted centers of the weaker acid, H(CHB11Cl11), resulted in breaking of the bridged H-bonds of the acid polymers without proton transfer (PT) to CO. The binding occurred via the C atom (blue shift ΔνCO up to +155-167 cm(-1), without PT) or via O atom (red shift ΔνCO up to -110 cm(-1), without PT) always simultaneously, regardless of whether H(+) is transferred to CO. IR spectra of all species were interpreted by B3LYP/cc-pVQZ calculations of the simple models, which adequately mimic the ability of carborane acids to form LH(+)CO, LH(+)CO, COH(+)L, and COH(+)L compounds (L = bases). The CO bond in all compounds was triple. Acidic strength of the Brønsted centers of commonly used acid catalysts, even so-called superacidic catalysts, is not sufficient for the formation of the compounds studied.

    To assess effects of off-centering, automatic exposure control, and padding on attenuation values, noise, and radiation dose when using in-plane bismuth-based shields for CT scanning. A 30 cm anthropomorphic chest phantom was scanned on a 64-multidetector CT, with the center of the phantom aligned to the gantry isocenter. Scanning was repeated after placing a bismuth breast shield on the anterior surface with no gap and with 1, 2, and 6 cm of padding between the shield and the phantom surface. The 'shielded' phantom was also scanned with combined modulation and off-centering of the phantom at 2 cm, 4 cm and 6 cm below the gantry isocenter. CT numbers, noise, and surface radiation dose were measured. The data were analyzed using an analysis of variance. The in-plane shield was not associated with any significant increment for the surface dose or CT dose index volume, which was achieved by comparing the radiation dose measured by combined modulation technique to the fixed mAs (p > 0.05). Irrespective of the gap or the surface CT numbers, surface noise increased to a larger extent compared to Hounsfield unit (HU) (0-6 cm, 26-55%) and noise (0-6 cm, 30-40%) in the center. With off-centering, in-plane shielding devices are associated with less dose savings, although dose reduction was still higher than in the absence of shielding (0 cm off-center, 90% dose reduction; 2 cm, 61%) (p < 0.0001). Streak artifacts were noted at 0 cm and 1 cm gaps but not at 2 cm and 6 cm gaps of shielding to the surface distances. In-plane shields are associated with greater image noise, artificially increased attenuation values, and streak artifacts. However, shields reduce radiation dose regardless of the extent of off-centering. Automatic exposure control did not increase radiation dose when using a shield.

    The words "chemical and biological weapons" (CBW) send a shiver down most spines these days. With the end of the Cold War, the possibility of a massive nuclear confrontation appears remote, so today many popular doomsday scenarios center on the aggressive use of chemical or biological warfare by rogue nations or terrorist groups. As exaggerated as some of the accounts are, with CBW cast as the latest unseen, unstoppable enemy, the threat posed by these weapons is all too real, and growing. Images p931-a PMID:10585899

  2. Why are U.S. nuclear weapon modernization efforts controversial?

    Science.gov (United States)

    Acton, James

    2016-03-01

    U.S. nuclear weapon modernization programs are focused on extending the lives of existing warheads and developing new delivery vehicles to replace ageing bombers, intercontinental ballistic missiles, and ballistic missile submarines. These efforts are contested and controversial. Some critics argue that they are largely unnecessary, financially wasteful and potentially destabilizing. Other critics posit that they do not go far enough and that nuclear weapons with new military capabilities are required. At its core, this debate centers on three strategic questions. First, what roles should nuclear weapons be assigned? Second, what military capabilities do nuclear weapons need to fulfill these roles? Third, how severe are the unintended escalation risks associated with particular systems? Proponents of scaled-down modernization efforts generally argue for reducing the role of nuclear weapons but also that, even under existing policy, new military capabilities are not required. They also tend to stress the escalation risks of new--and even some existing--capabilities. Proponents of enhanced modernization efforts tend to advocate for a more expansive role for nuclear weapons in national security strategy. They also often argue that nuclear deterrence would be enhanced by lower yield weapons and/or so called bunker busters able to destroy more deeply buried targets. The debate is further fueled by technical disagreements over many aspects of ongoing and proposed modernization efforts. Some of these disagreements--such as the need for warhead life extension programs and their necessary scope--are essentially impossible to resolve at the unclassified level. By contrast, unclassified analysis can help elucidate--though not answer--other questions, such as the potential value of bunker busters.

  3. Mobility of chemisorbed molecules and surface regeneration of active centers during dehydration of isopropanol on aluminium oxide and aluminosilicate

    By a differential isotope method involving 14 C the authors have investigated the surface mobility of chemisorbed molecules of isopropanol during its dehydration in an adsorption layer on aluminium oxide and aluminosilicate. The chemisorbed alcohol molecules possess marked surface mobility which plays a decisive part in the mechanism of surface regeneration of the active catalyst centers in the process of dehydration. The cessation of the reaction long before the adsorbed alcohol is completely used up is explained by the hypothesis that there is local overpopulation of the active sectors by water formed by the reaction; this hinders further surface regeneration and repetition of the elementary events of dehydration

In the current era, rising geopolitical tensions between the United States and Russia and China have led to assumptions in all three major space powers that warfighting in space now is inevitable, and possible because of rapid technological advancements. New capabilities for disrupting and destroying satellites include radio-frequency jamming, the use of lasers, maneuverable space objects and more capable direct-ascent anti-satellite weapons. This situation, however, threatens international security and stability among nuclear powers. There is a continuing and necessary role for diplomacy, especially the establishment of normative rules of behavior, to reduce risks of misperceptions and crisis escalation, including up to the use of nuclear weapons. U.S. policy and strategy should seek a balance between traditional military approaches to protecting its space assets and diplomatic tools to create a more secure space environment.

    Synthetic diamond production is a key to the development of quantum metrology and quantum information applications of diamond. The major quantum sensor and qubit candidate in diamond is the nitrogen-vacancy (NV) color center. This lattice defect comes in four different crystallographic orientations leading to an intrinsic inhomogeneity among NV centers, which is undesirable in some applications. Here, we report a microwave plasma-assisted chemical vapor deposition diamond growth technique on (111)-oriented substrates, which yields perfect alignment (94% ± 2%) of as-grown NV centers along a single crystallographic direction. In addition, clear evidence is found that the majority (74% ± 4%) of the aligned NV centers were formed by the nitrogen being first included in the (111) growth surface and then followed by the formation of a neighboring vacancy on top. The achieved homogeneity of the grown NV centers will tremendously benefit quantum information and metrology applications

    2017-04-01

    The World Radiation Monitoring Center (WRMC) is the central archive of the Baseline Surface Radiation Network (BSRN). The BSRN was initiated by the World Climate Research Programme (WCRP) Working Group on Radiative Fluxes and began operations in 1992. One of its aims is to provide short and long-wave surface radiation fluxes of the best possible quality to support the research projects of the WCRP and other scientific projects. The high quality, uniform and consistent measurements of the BSRN network can be used to monitor the short- and long-wave radiative components and their changes with the best methods currently available, to validate and evaluate satellite-based estimates of the surface radiative fluxes, and to verify the results of global climate models. In 1992 the BSRN/WRMC started at ETH Zurich, Switzerland with 9 stations. Since 2007 the archive is hosted by the Alfred-Wegener-Institut (AWI) in Bremerhaven, Germany (http://www.bsrn.awi.de/) and comprises a network of currently 59 stations in contrasting climatic zones, covering a latitude range from 80°N to 90°S. Of the 59 stations, 23 offer the complete radiation budget (down- and upwelling short- and long-wave data). In addition to the ftp-service access instituted at ETH Zurich, the archive at AWI offers data access via PANGAEA - Data Publisher for Earth & Environmental Science (https://www.pangaea.de). PANGAEA guarantees the long-term availability of its content through a commitment of the operating institutions. Within PANGAEA, the metadata of the stations are freely available. To access the data itself an account is required. If the scientist accepts to follow the data release guidelines of the archive (http://bsrn.awi.de/data/conditions-of-data-release/) he or she can get an account from amelie.driemel@awi.de. Currently, more than 9,400 station months (>780 years) are available for interested scientists (see also https://dataportals.pangaea.de/bsrn/?q=LR0100 for an overview on available data

    Total body surface area (TBSA) burned is a powerful descriptor of burn severity and influences the volume of resuscitation required in burn patients. The incidence and severity of TBSA overestimation by referring institutions (RIs) in children transferred to a burn center (BC) are unclear. The association between TBSA overestimation and overresuscitation is unknown as is that between TBSA overestimation and outcome. The trauma registry at a BC was queried over 7.25 years for children presenting with burns. TBSA estimate at RIs and BC, total fluid volume given before arrival at a BC, demographic variables, and clinical variables were reviewed. Nearly 20 per cent of children arrived from RIs without TBSA estimation. Nearly 50 per cent were overestimated by 5 per cent or greater TBSA and burn sizes were overestimated by up to 44 per cent TBSA. Average TBSA measured at BC was 9.5 ± 8.3 per cent compared with 15.5 ± 11.8 per cent as measured at RIs (P < 0.0001). Burns between 10 and 19.9 per cent TBSA were overestimated most often and by the greatest amounts. There was a statistically significant relationship between overestimation of TBSA by 5 per cent or greater and overresuscitation by 10 mL/kg or greater (P = 0.02). No patient demographic or clinical factors were associated with TBSA overestimation. Education efforts aimed at emergency department physicians regarding the importance of always calculating TBSA as well as the mechanics of TBSA estimation and calculating resuscitation volume are needed. Further studies should evaluate the association of TBSA overestimation by RIs with adverse outcomes and complications in the burned child.

  15. Prerequisites for a nuclear weapons convention

    1999-01-01

    A Nuclear Weapons Convention (NWC) would prohibit the research, development, production, testing, stockpiling, transfer, use and threat of use of nuclear weapons and would serve their total elimination.' In this fashion it follows the model laid out by the biological and chemical weapons conventions. The NWC would encompass a few other treaties and while replacing them should learn from their experiences. The Nuclear Weapons Convention should at some given point in the future replace the Non-Proliferation Treaty (NPT) and so resolve its contradictions and shortcomings. The main objectives of an NWC Would be: reduction of the nuclear arsenals of the 'five' nuclear weapons powers down to zero within a set of fixed periods of time; elimination of stockpiles of weapons-usable materials and, where existent, nuclear warheads in de-facto nuclear weapon and threshold states; providing assurance that all states will retain their non-nuclear status forever

  16. Disposition of excess weapons plutonium from dismantled weapons

    International Nuclear Information System (INIS)

    Jardine, L.J.

    1997-01-01

    With the end of the Cold War and the implementation of various nuclear arms reduction agreements, US and Russia have been actively dismantling tens of thousands of nuclear weapons. As a result,large quantities of fissile materials, including more than 100 (tonnes?) of weapons-grade Pu, have become excess to both countries' military needs. To meet nonproliferation goals and to ensure the irreversibility of nuclear arms reductions, this excess weapons Pu must be placed in secure storage and then, in timely manner, either used in nuclear reactors as fuel or discarded in geologic repositories as solid waste. This disposition in US and Russia must be accomplished in a safe, secure manner and as quickly as practical. Storage of this Pu is a prerequisite to any disposition process, but the length of storage time is unknown. Whether by use as fuel or discard as solid waste, disposition of that amount of Pu will require decades--and perhaps longer, if disposition operations encounter delays. Neither US nor Russia believes that long-term secure storage is a substitute for timely disposition of excess Pu, but long-term, safe, secure storage is a critical element of all excess Pu disposition activities

    The immediate problem facing us with respect to proliferation and nuclear power involves reprocessing and the availability of plutonium from reprocessing plants. One solution supported by the Atomic Industrial Forum is that reprocessing centers be restricted to locations in those industrial nations already having weapons capability and that the energy of the reprocessed plutonium be returned to the user nation in the form of low enriched uranium. Thus, the plutonium would remain where it would not add to problems of proliferation

    The satellite detection of a nuclear explosion in the South Atlantic and Israel's destruction of a research reactor in Iraq make it essential to strengthen existing monitoring and enforcement programs to prevent proliferation. While there was no reliable evidence that either South Africa or Iraq was violating non-proliferation agreements, worst case scenarios can demonstrate to unfriendly countries that South Africa had diverted fuel to test a nuclear weapon and that Iraq is intending to produce weapons-grade plutonium 239. The situation can be improved by formulating better terms and conditions for internationalizing access to materials. Nuclear suppliers need to agree on terms that will assure their customers that contracts for civil programs will be honored. The International Atomic Energy Agency (IAEA), which includes both nuclear suppliers and customers, could achieve stronger agreements that take into account recent technological advances that will expand enrichment and reprocessing activities. 23 references, 1 figure

    The debate concerns the authorisation of payment of the money required to reorganise the atomic weapons establishment in the United Kingdom provided for in the Atomic Weapons Establishment Bill in progress through Parliament. In the Bill the contractorisation of the establishment is recommended and some sort of Government owned company operated scheme set up. The debate lasted about half an hour and is reported verbatim. The issues raised concerned the actual sums likely to be incurred in the formation of a Company to carry out the designated activities of the Bill. These are connected with the research, development, production or maintenance of nuclear devices and the premises needed. The government spokesman suggested the sums required to support the Bill would not be large and the resolution was agreed to without a vote. (UK)

    It is shown that surface color centers of the same type are formed in the surface layer and in regions with damaged crystal structure inside crystalline lithium fluoride after γ-irradiation. Results are presented from a study of the effect of pre-irradiation annealing on the efficiency with which surface centers are formed in lithium fluoride nanocrystals. Raising the temperature for pre-irradiation annealing from room temperature to 250°C leads to a substantial reduction in the efficiency with which these centers are created. Surface color centers are not detected after γ-irradiation for pre-irradiation annealing temperatures of 300°C and above. Adsorption of atmospheric gases on the crystal surface cannot be regarded as a necessary condition for the formation of radiation-induced surface centers.

Some of these phenomena became known only as a result of the use or testing of bombs and are not as yet fully understood. They produce physical or biological effects or both, almost all of which are directly detrimental to human health. Some are likely to damage the environment

  5. Quantum Control of a Nitrogen-Vacancy Center using Surface Acoustic Waves in the Resolved Sideband Limit

    Science.gov (United States)

    Golter, David; Oo, Thein; Amezcua, Maira; Wang, Hailin

    Micro-electromechanical systems research is producing increasingly sophisticated tools for nanophononic applications. Such technology is well-suited for achieving chip-based, integrated acoustic control of solid-state quantum systems. We demonstrate such acoustic control in an important solid-state qubit, the diamond nitrogen-vacancy (NV) center. Using an interdigitated transducer to generate a surface acoustic wave (SAW) field in a bulk diamond, we observe phonon-assisted sidebands in the optical excitation spectrum of a single NV center. This exploits the strong strain sensitivity of the NV excited states. The mechanical frequencies far exceed the relevant optical linewidths, reaching the resolved-sideband regime. This enables us to use the SAW field for driving Rabi oscillations on the phonon-assisted optical transition. These results stimulate the further integration of SAW-based technologies with the NV center system.

  6. Anti-3D Weapon Model Detection for Safe 3D Printing Based on Convolutional Neural Networks and D2 Shape Distribution

    2018-03-01

    Full Text Available With the development of 3D printing, weapons are easily printed without any restriction from the production managers. Therefore, anti-3D weapon model detection is necessary issue in safe 3D printing to prevent the printing of 3D weapon models. In this paper, we would like to propose an anti-3D weapon model detection algorithm to prevent the printing of anti-3D weapon models for safe 3D printing based on the D2 shape distribution and an improved convolutional neural networks (CNNs. The purpose of the proposed algorithm is to detect anti-3D weapon models when they are used in 3D printing. The D2 shape distribution is computed from random points on the surface of a 3D weapon model and their geometric features in order to construct a D2 vector. The D2 vector is then trained by improved CNNs. The CNNs are used to detect anti-3D weapon models for safe 3D printing by training D2 vectors which have been constructed from the D2 shape distribution of 3D weapon models. Experiments with 3D weapon models proved that the D2 shape distribution of 3D weapon models in the same class is the same. Training and testing results also verified that the accuracy of the proposed algorithm is higher than the conventional works. The proposed algorithm is applied in a small application, and it could detect anti-3D weapon models for safe 3D printing.

  7. For a convention for nuclear weapon elimination

These two texts are contributions presented in London at the Global Summit for a Nuclear Weapon-free World. The first one calls into question the deterrence principle and the idea of a nuclear weapon-based security. It calls for different forms of action to promote a nuclear weapon-free world. The second text stresses the role and the responsibility of states with nuclear weapons in nuclear disarmament and in the reinforcement of the nuclear non proliferation treaty (NPT)

    Full Text Available Abstract Background The threat posed by the use of weapons of mass destruction (WMD within the United States has grown significantly in recent years, focusing attention on the medical and public health disaster capabilities of the nation in a large scale crisis. While the hundreds of thousands or millions of casualties resulting from a nuclear weapon would, in and of itself, overwhelm our current medical response capabilities, the response dilemma is further exacerbated in that these resources themselves would be significantly at risk. There are many limitations on the resources needed for mass casualty management, such as access to sufficient hospital beds including specialized beds for burn victims, respiration and supportive therapy, pharmaceutical intervention, and mass decontamination. Results The effects of 20 kiloton and 550 kiloton nuclear detonations on high priority target cities are presented for New York City, Chicago, Washington D.C. and Atlanta. Thermal, blast and radiation effects are described, and affected populations are calculated using 2000 block level census data. Weapons of 100 Kts and up are primarily incendiary or radiation weapons, able to cause burns and start fires at distances greater than they can significantly damage buildings, and to poison populations through radiation injuries well downwind in the case of surface detonations. With weapons below 100 Kts, blast effects tend to be stronger than primary thermal effects from surface bursts. From the point of view of medical casualty treatment and administrative response, there is an ominous pattern where these fatalities and casualties geographically fall in relation to the location of hospital and administrative facilities. It is demonstrated that a staggering number of the main hospitals, trauma centers, and other medical assets are likely to be in the fatality plume, rendering them essentially inoperable in a crisis. Conclusion Among the consequences of this

    We report a scheme for investigating two-step stimulated structure change of luminescence centers. Amorphous silica nanospheres with uniform diameter of 9–15 nm have been synthesized by Stöber method. Strong hydroxyl-related infrared-absorption band is observed in infrared spectrum. The surface hydroxyl groups exert great influence on the luminescent behavior of silica. They provide stable and intermediate energy states to accommodate excitation electrons. The existence of these surface states reduces the energy barrier of photochemical reactions, creating conditions for two-step excitation process. By carefully examining excitation and emission process, the nearest excitation band is absent in both optical absorption spectrum and excitation spectrum. This later generated state confirms the generation of new luminescence centers as well as the existence of photochemical reactions. Stimulated by different energies, two-step excitation process impels different photochemical reactions, prompting generation of different lattice defects on surface area of silica. Thereby, tunable luminescence is achieved. After thermal treatment, strong gap excitation band appears with the disappearance of strong surface excitation band. Strong blue luminescence also disappears. The research is significance to precise introducing structural defects and controlling position of luminescence peaks.

    International Nuclear Information System (INIS)

    Zhigalov, V.

    1998-01-01

    A serious psychological barrier to acceptance of the concept for achieving the nuclear-weapon-free world is fear of facing the prospect that one or more nations or extremist political groups might develop their own nuclear weapons. Actually this is a question of stability of the nuclear-weapon-free world. From this point of view the most effective system of verification is an absolute necessity. This system must ensure detection of so called undeclared nuclear activity at early stage. Scientists of Russian nuclear centers are working today on solving this problem. This paper is considered to be a comprehensive attempt to analyze the technical and organizational aspects of the problems of transition to a nuclear-weapons-free world, setting aside the difficulties of resolving purely political problems

    2015-03-01

    We present a simple and effective method of loading particles into an optical trap. Our primary application of this method is loading photoluminescent material, such as diamond nanocrystals containing nitrogen-vacancy (NV) centers, for coupling the mechanical motion of the trapped crystal with the spin of the NV centers. Highly absorptive material at the trapping laser frequency, such as tartrazine dye, is used as media to attach nanodiamonds and burn into a cloud of air-borne particles as the material is swept near the trapping laser focus on a glass slide. Particles are then trapped with the laser used for burning or transferred to a second laser trap at a different wavelength. Evidence of successful loading diamond nanocrystals into the trap presented includes high sensitivity of the photoluminecscence (PL) to the excitation laser and the PL spectra of the optically trapped particles

    2007-01-01

    Purpose: Since the invasion into Iraq in 2003, weapons of mass destruction (WMD), have come to general notice; they include today chemical, biological, and atomic/nuclear weapons, (CW, BW, and AW). Radiological findings shall be described. Material and methods: X-ray findings of victims of WMD are described. From CW, own observations are reported. Examples of (possible) X-ray findings of victims of BW are described. AW may induce radiation disease. Results: Exposure to sulfur-lost induces severe bronchitis; if the radiograph shows pulmonary infiltrations, the prognosis is bad; a late consequence maybe bronchiectasis. BW can be based on bacteria, virus or toxins. An approach of the X-ray findings for BW victims is based on the assumption that the disease induced by BW has the same (or a similar) clinic and radiology as that induced by the original microorganism or by the unchanged toxism. This approximation may have its limits, if the germ or toxin has been modified. In survivors of AW, the radiology is probably that of victims of thermal radiation and blast. Conclusion: WMD seem to be a real or a possible threat. They can be used in war, in terrorist attacks, in crime, and in action of secret services. In case that WMD are employed, X-ray diagnostic will be used to evaluate the prognosis (triage) and the risk of infection

An approach of the X-ray findings for BW victims is based on the assumption that the disease induced by BW has the same (or a similar) clinic and radiology as that induced by the original microorganism or by the unchanged toxism. This approximation may have its limits, if the germ or toxin has been modified. In survivors of AW, the radiology is probably that of victims of thermal radiation and blast. Conclusion: WMD seem to be a real or a possible threat. They can be used in war, in terrorist attacks, in crime, and in action of secret services. In case that WMD are employed, X-ray diagnostic will be used to evaluate the prognosis (triage) and the risk of infection.

    Techniques incorporating wind convergence that can be used for the short-term prediction of thunderstorm development are described. With these techniques, the convergence signal is sensed by the wind network array 15 to 90 min before actual storm development. Particular attention is given to the convergence cell technique (which has been applied at the Kennedy Space Center) where each convective region is analyzed independently. It is noted that, while the monitoring of areal and cellular convergence can be used to help locate the seeds of developing thunderstorms and pinpoint the lightning threat areas, this forecasting aid cannot be used in isolation.

  1. Weapons material and the commercial fuel cycle

    In 1991, the United States and the former USSR had arsenals of ∼18,000 and 27,200 nuclear weapons, respectively. Approximately 10,000 of the US and 13,000 of the former USSR weapons were in the strategic category, and the remainder were tactical weapons. The dramatic changes in the political climate between the United States and the republics of the former USSR have resulted in the signing of the Strategic Arms Reduction Treaty (START I and II), agreements to substantially reduce nuclear weapons arsenals. Tactical weapons have already been collected in Russia, and strategic weapons are to be collected by the end of 1994. The major issues in accomplishing the treaty reductions appear to be funding, transport safety, storage capacity, and political issues between Russia and Ukraine because the latter seems to be using its weapons for political leverage on other matters. Collectively, the US and former USSR warhead stockpiles contain tremendous inventories of high-enriched uranium and weapons-grade plutonium which if converted to light water reactor fuel would equate to an enormous economic supply of natural uranium, conversion services, and enrichment separative work. The potential for this material entering the light water reactor fuel marketplace was enhanced in July 1992, when the two US industrial companies, Nuclear Fuel Services and Allied-Signal, announced that they had reached a preliminary agreement with the Russian ministry, Minatom, and the Russian Academay of Sciences to convert Russian high-enriched uranium to low-enriched uranium

    Cloud-to-ground lightning is related in time and space to surface convergence for 244 days during the summer over a 790 sqkm network. The method uses surface convergence, particularly the average over the area, to identify the potential for new, local thunderstorm growth, and can be used to specify the likely time and location of lightning during the life cycle of the convection. A threshold of 0.0000075/sec change in divergence is used to define a convergence event, and a separation of 30 min between flashes defines a lightning event. Time intervals are found to be on the order of 1 hr from beginning convergence to first flash, and (CH110) 2 hr from beginning convergence to the end of lightning. Major differences between the convergence-lightning relationships based on low-level mean onshore and offshore flow are noted.

  5. Consequences of the Use of Neutron Weapons

    1998-01-01

    In modern conceptions of the use of nuclear weapons there is a significant role of so called enhanced radiation weapons, also known as neutron weapons. Its most important feature is that all other effects (blast, thermal) are minimized in favour of neutron radiation. Because of the great penetrative capability and biological efficiency, neutron beam is ideal weapon against people in shelters and armoured vehicles. Material goods stay saved and also there is no significant long- term radioactive contamination. After the use of this weapons, which is possible even for tactical tasks on limited area, one must count with great number of people irradiated with doses in wide range - from those enough for instantaneous incapacitation to those which cause only long-term effects. For the purpose of maximal efficiency in this situation, it is necessary to work out plans for dosimetric control, first aid, transport and medical treatment of irradiated people (soldiers and civilians) in war conditions.

  6. Nuclear experts and nuclear weapons proliferation

    International Nuclear Information System (INIS)

    Mueller, H.

    1979-01-01

    In Germany the issue of nuclear weapons proliferation has attracted scant attention. Most potential nuclear weapon states are important trade partners of the FRG and, since further proliferation of nuclear weapons could worsen conflicts involving these, it should be in the FRG's interest to limit proliferation. The security of the FRG is also dependent on the common interest of the great powers to avoid nuclear war. The contradictory positions of Usa and the USSR on nuclear weapons policy regarding themselves and non-nuclear weapon states encourages less developed countries to see nuclear weaponry as useful. The NPT and IAEA safeguards have only limited inhibiting effect. The nuclear export policy of the FRG has been dominated by short term economic advantage, neglecting the negative long term effects of decreased political stability. The FRG should formulate a policy based on self-restraint, positive stimuli and extension of controls, using its economic strength to deter proliferation. (JIW)

    , making it the only state ever to do so, and in February 2005 it declared that it possessed nuclear weapons. It attempted long-range missile launches in July 2006 and April 2009, conducted nuclear tests in October 2006 and May 2009, and since late 2008 has claimed status as a nuclear weapons state outside the NPT. The shortcomings and outright failures in nuclear diplomacy with the DPRK have a long lineage. Under the Agreed Framework of October 1994, the Clinton Administration bought time by freezing North Korea's plutonium production capabilities, but a comprehensive resolution of controversies that triggered the first nuclear crisis was deferred indefinitely. The Bush Administration was openly contemptuous of the arrangements negotiated under its predecessor and walked away from the Agreed Framework, but it lacked a credible fallback plan when Pyongyang resumed its plutonium-based activities. Some senior Bush Administration officials, moreover, were convinced that North Korea would wilt under pressure or even collapse outright, but the DPRK defied such expectations, and moved quickly toward an avowed weapons capability. The DPRK's long pursuit of strategic autonomy, however, remains at the center of this story, and starkly contradicts the North's claims that it is intent on a non-nuclear future. North Korea signed various agreements that, at least in theory, invalidated pursuit of nuclear weapons. These agreements included Pyongyang's assent to basic non-proliferation documents; an inter-Korean accord that entered into force in 1992; bilateral agreements with the United States; and multilateral declarations negotiated at the Six-Party Talks in Beijing in 2005 and 2007. But negotiated agreements failed to eliminate the North Korea's pursuit of the technologies and expertise necessary for a weapons program. By walking away from these agreements, Pyongyang compelled Washington and other capitals to undertake reassessments of previous policies. (author)

    2015-10-01

    After having evoked the behaviour of nuclear countries regarding the development of nuclear weapons and uranium procurement, or nuclear programmes after the Second World War until nowadays, the author presents the non proliferation Treaty (NPT) as a construction at the service of super-powers. He comments and discusses the role of the IAEA control system and its evolutions: a control limited to declared installations, an export control with the spectre of plutonium, a control system thwarted by some technological innovations, information systems coming in, and an additional protocol related to the application of guarantees. He comments the evolution of the context from a bipolar world to a world without pole which raises the issue of how to have commitments respected: description of the role and practice of non proliferation during the Cold War, after the Cold War, and in a world without governance

    We all want to prevent the use of nuclear weapons. The issue before us is how best to achieve this objective; more specifically, whether the peaceful applications of nuclear energy help or hinder, and to what extent. Many of us in the nuclear industry are working on these applications from a conviction that without peaceful nuclear energy the risk of nuclear war would be appreciably greater. Others, however, hold the opposite view. In discussing the subject, a necessary step in allaying fears is understanding some facts, and indeed facing up to some unpalatable facts. When the facts are assessed, and a balance struck, the conclusion is that peaceful nuclear energy is much more part of the solution to preventing nuclear war than it is part of the problem

    1983-01-01

    This reviews the work of AWRE at Aldermaston and Foulness. The main programme is nuclear and is concerned with the design and development of warheads for strategic and tactical nuclear weapons for the British nuclear deterrent, including those for the Royal Navy's missile carrying submarine fleet. The work is described grouped as design physics, development and materials. Services to these groups and to the whole establishment are provided by Engineering, Safety and Administration. The work ranges from long-term fundamental research, the development of technology, design, prototype development to the environmental testing of engineered products. In materials research the emphasis is on plutonium, uranium and beryllium, on high explosives and a wide range of inorganic and organic materials. The physics of the earth's crust is studied to aid detection of underground nuclear explosions. Reactor research facilities include the two reactors, Herald and Viper. (U.K.)

  11. A comparative study on optical and magnetic resonance properties of near-surface NV centers in nano and bulk diamond

    2014-01-01

    Using shallow nitrogen-vacancy (NV) centers in diamond for applications in magnetometry requires the generation of stable defects in the NV charge state in sufficiently high density and high quality spin properties. Recent studies reported about NV defects close to the surface created by ion implantation or during chemical vapor deposition growth technique and in nanodiamonds point to a scenario where defects are stabilized in the neutral charge state and that the minority of negatively charged state defects have poor spin properties, i.e.g shorter coherence times compared to NV defects deeply localized in bulk diamond. This undesirable behavior appears to result from the interaction with rapidly fluctuating electric fields created by moving charges at the surface and with interface effects associated with the termination of the diamond surface. Here we report studies of photoluminescence and magnetic resonance properties of shallow NV ensembles created by low energy nitrogen ion implantation in electronic grade diamond substrate and nanodiamonds with low nitrogen concentration. We verified the shallow NV center spin properties through pulsed optically detected magnetic resonance (ODMR) protocols and found longitudinal time constant (T1) of a few milliseconds and transversal relaxation time constant (T2) of a few microseconds for shallow defects implanted in bulk diamond. For nanodiamonds, the T2 coherence time is similar to the case in bulk sample but on the other hand the T1 coherence time is ten times shorter than in bulk. Additionally was found the T2* is around one microsecond for shallow NV defects in bulk samples meanwhile in nanodiamonds it is around twenty nanoseconds. It worth to mention that all the measurements were performed in NV ensembles which show just two ODMR resonance lines with applied magnetic field as if they were magnetically equivalent. In that sense we are trying to apply chirped pulses and Ramsey pulse sequence to check this assumption

    Full Text Available Construction of the Olympic Games 2004 Sailing Center is planned in the Saronikos Gulf, in the area of Agios Kosmas. A multi-disciplinary base-line study was carried out to provide background levels of inorganic and organic pollutants before the construction. Two shallow reefs (water depth 2-3 m are the predominant features in the area’s underwater topography. The reef consists of solid rock formations and pebbles, whereas sandy sediments cover predominantly the remaining seabed. Some pockets of fine-grained sand were identified within the existing marina. Sedimentary heavy metal contents were found to be low, showing only slight heavy metal enrichment, attributed mainly to heavy mineral abundance in the area. A small enrichment for lead could be related to anthropogenic sources. Patterns of low concentrations were observed for organic carbon and organic nitrogen. Conversely, the sediment petroleum hydrocarbon content was found to be relatively high, implying anthropogenic pollution related to ship effluents and increased marine traffic.

    Weapons related webpages from nine cryptomarkets were manually duplicated in February 2016. Information about the listings (i.e. sales proposals) and vendors' profiles were extracted to draw an overview of the actual online trafficking of weapons. Relationships between vendors were also inferred through the analysis of online digital traces and content similarities. Weapons trafficking is mainly concentrated on two major cryptomarkets. Besides, it accounts for a very small proportion of the illicit trafficking on cryptomarkets compared to the illicit drugs trafficking. Among all weapon related listings (n=386), firearms only account for approximately 25% of sales proposal since the proportion of non-lethal and melee weapons is important (around 46%). Based on the recorded pseudonyms, a total of 96 vendor profiles were highlighted. Some pseudonyms were encountered on several cryptomarkets, suggesting that some vendors may manage accounts on different markets. This hypothesis was strengthened by comparing pseudonyms to online traces such as PGP keys, images and profiles descriptions. Such a method allowed to estimate more accurately the number of vendors offering weapons across cryptomarkets. Finally, according to the gathered data, the extent of the weapons trafficking on the cryptomarkets appear to be limited compared to other illicit goods. Copyright © 2017 Elsevier B.V.

    Although the spin properties of superficial shallow nitrogen-vacancy (NV) centers have been the subject of extensive scrutiny, considerably less attention has been devoted to studying the dynamics of NV charge conversion near the diamond surface. Using multicolor confocal microscopy, here we show that near-surface point defects arising from high-density ion implantation dramatically increase the ionization and recombination rates of shallow NVs compared to those in bulk diamond. Further, we find that these rates grow linearly, not quadratically, with laser intensity, indicative of single-photon processes enabled by NV state mixing with other defect states. Accompanying these findings, we observe NV ionization and recombination in the dark, likely the result of charge transfer to neighboring traps. Despite the altered charge dynamics, we show that one can imprint rewritable, long-lasting patterns of charged-initialized, near-surface NVs over large areas, an ability that could be exploited for electrochemical biosensing or to optically store digital data sets with subdiffraction resolution.

  17. Collector for recovering gallium from weapons plutonium

    1998-09-01

    Currently, the separation of gallium from weapons plutonium involves the use of aqueous processing using either solvent extraction of ion exchange. However, this process generates significant quantities of liquid radioactive wastes. A Thermally Induced Gallium Removal process, or TIGR, developed by researchers at Los Alamos National Laboratories, is a simpler alternative to aqueous processing. This research examined this process, and the behavior of gallium suboxide, a vapor that is swept away by passing hydrogen/argon over gallium trioxide/plutonium oxide heated at 1100 C during the TIGR process. Through experimental procedures, efforts were made to prevent the deposition of corrosive gallium onto furnace and vent surfaces. Experimental procedures included three options for gallium removal and collection: (1) collection of gallium suboxide through use of a cold finger; (2) collection by in situ air oxidation; and (3) collection of gallium on copper. Results conclude all three collection mechanisms are feasible. In addition, gallium trioxide exists in three crystalline forms, and each form was encountered during each experiment, and that each form will have a different reactivity

    2011-03-01

    Although chemicals have been reportedly used as weapons for thousands of years, it was not until 1915 at Ypres, France that an industrial chemical, chlorine, was used in World War I as an offensive weapon in significant quantity, causing mass casualties. From that point until today the development, detection, production and protection from chemical weapons has be an organized endeavor of many of the world's armed forces and in more recent times, non-governmental terrorist organizations. The number of Chemical Warfare Agents (CWAs) has steadily increased as research into more toxic substances continued for most of the 20 th century. Today there are over 70 substances including harassing agents like tear gas, incapacitating agents, and lethal agents like blister, blood, chocking, and nerve agents. The requirements for detecting chemical weapons vary depending on the context in which they are encountered and the concept of operation of the organization deploying the detection equipment. The US DoD, for example, has as a requirement, that US forces be able to continue their mission, even in the event of a chemical attack. This places stringent requirements on detection equipment. It must be lightweight (developed for this application, including, but not limited to: mass spectroscopy, IR spectroscopy, RAMAN spectroscopy, MEMs micro-cantilever sensors, surface acoustic wave sensors, differential mobility spectrometry, and amplifying fluorescence polymers. In the future the requirements for detection equipment will continue to become even more stringent. The continuing increase in the sheer number of threats that will need to be detected, the development of binary agents requiring that even the precursor chemicals be detected, the development of new types of agents unlike any of the current chemistries, and the expansion of the list of toxic industrial chemical will require new techniques with higher specificity and more sensitivity.

    Sun, Kai; Tao, Min-Long; Tu, Yu-Bing; Wang, Jun-Zhong

    2017-05-04

    Molecular rotors with an off-center axis and the chiral feature of achiral CuPc molecules on a semi-metallic Bi(111) surface have been investigated by means of a scanning tunneling microscopy (STM) at liquid nitrogen (LN₂) temperature. The rotation axis of each CuPc molecular rotor is located at the end of a phthalocyanine group. As molecular coverage increases, the CuPc molecules are self-assembled into various nanoclusters and finally into two-dimensional (2D) domains, in which each CuPc molecule exhibits an apparent chiral feature. Such chiral features of the CuPc molecules can be attributed to the combined effect of asymmetric charge transfer between the CuPc and Bi(111) substrate, and the intermolecular van der Waals interactions.

    The use of chemical or biological weapons, whether by a State or terrorists, continues to be a serious security concern. Both types of weapons are prohibited by multilateral treaties that have very broad membership, but both the Biological Weapons Convention and the Chemical Weapons Convention are facing major challenges. In particular, the continued use of chemical weapons in the Syrian civil war by government forces risks eroding the norm against the use of such weapons. This paper briefly explore the recent history of efforts to constrain chemical and biological weapons and outlines challenges for the future.

    Russett, B.

    1989-01-01

    To the degree that people's fears of nuclear war are deep and pervasive, they become subject to manipulation by cynical or politically utopian promises, whether those promises be to abolish nuclear weapons from the earth or to create a leakproof peace shield (SDI). But the basic yearning for protection could also be mobilized to support serious arms reduction and arms control agreements. Nuclear weapons provide the basis for a vivid form of symbolic politics, perhaps equivalent in foreign policy considerations to the Korean and Vietnam wars during their durations, and in similar ways (although not necessarily as severe) as unemployment does among domestic policy issues. This paper presents survey research directed specifically at the role of public opinion on nuclear imagery (difference between expectation of nuclear war versus any kind of weapon war; willingness to spend on nuclear weapons versus conventional ones or general defense spending) can help in understanding these phenomena

    In 1993, the U.S.A. and the CIS signed Start 2 (the Strategic Arms Reduction Treaty) in which they committed themselves the reduce their nuclear weapon arsenals to a fraction of that of 1991. For forty-five years the antagonism between the superpowers had been a dominating factor in world history, determining large areas of social life. When Start 2 will have been completed in 2003, some 200 t of weapon grade plutonium and some 2000 t of highly enriched uranium (Heu) will arise from dismantling nuclear weapons. In the absence of the ideological ballast of the debate about Communism versus Capitalism of the past few decades there is a chance of the grave worldwide problem of safe disposal and utilization of this former nuclear weapon material being solved. Under the heading of 'swords turned into plowshares', plutonium and uranium could be used for peaceful electricity generation. (orig.) [de

    2005-01-01

    This publication brings a complex and comprehensive view of the weapons of mass destruction phenomenon in the context of present military and political situation. It emphasizes the threat posed by proliferation of these destructive devices and their carriers as well as the threat present in their possession by unpredictable totalitarian regimes or terrorist groups. The publication is structured into four basic parts: Introduction Into The Topic, Nuclear Weapons, Chemical Weapons and Biological Weapons. The Introduction reflects the latest developments on the field of military technologies, which lead to the development of new destructive devices with characteristics comparable to basic types of WMDs - nuclear, chemical and biological. Based on the definition of WMD as 'weapon systems with enormous impact causing mass destruction, population, equipment and material losses', the modern mass destruction devices are assorted here, such as ecological, radiological and beam weapons, aerosol and container intelligent ammunition, the outburst of dangerous chemical substances from infrastructure, non-conventional weapons and military devices. The Nuclear Weapons part depicts the most destructive device of mass destruction mankind ever invented in close detail. It maps the history of most significant discoveries in nuclear physics, development and construction of the first nuclear weapons, accumulation of nuclear warheads and their carriers in the Cold war era, attempts of nuclear disarmament and reducing the number of nuclear weapons in possession of superpowers and their proliferation in the world's crisis regions including North Korea and Iran. The chapters devoted to theoretical grounds and physical principles of nuclear and thermonuclear weapons' functioning, the main categories and types, as well as destructive effects and consequences of use contain an adequate mathematical apparatus. This chapter's conclusion brings the overview of nuclear armament of states that

  7. Oil and influence: the oil weapon examined

    Energy Technology Data Exchange (ETDEWEB)

    Maull, H

    1975-01-01

    The term ''oil weapon'' as used here signifies any manipulation of the price and/or supply of oil by exporting nations with the intention of changing the political behavior of the consumer nations. The political potential of the oil price is fairly restricted so, in effect, the supply interruptions are of prime concern. Manipulating price does, in principle, offer the possibilities of both conferring rewards and inflicting sanctions. Oil could be sold on preferential prices and terms. A precondition for using the oil weapon successfully would be the ability to cause real and serious damage to the consumer countries. Four damaging potentials for using the oil weapon could include its application by: (1) one producer against one consumer; (2) one producer against all consumers; (3) a group of producers against one consumer; and (4) by a group of producers against all consumers. It is concluded that the oil weapon will continue to be a force in the international system. (MCW)

    1995-01-01

    The American Association for the Advancement of Science sponsored a seminar during September 1993 in Kiev, Ukraine, titled, ''Toward a Nuclear-Free Future--Barriers and Problems.'' It brought together Ukrainians, Belarusians and Americans to discuss the legal, political, economic, technical, and safeguards and security dimensions of nuclear weapons dismantlement and destruction. US representatives initiated discussions on legal and treaty requirements and constraints, safeguards and security issues surrounding dismantlement, storage and disposition of nuclear materials, warhead transportation, and economic considerations. Ukrainians gave presentations on arguments for and against the Ukraine keeping nuclear weapons, the Ukrainian Parliament's nonapproval of START 1, alternative strategies for dismantling silos and launchers, and economic and security implications of nuclear weapons removal from the Ukraine. Participants from Belarus discussed proliferation and control regime issues. This paper will highlight and detail the issues, concerns and possible impacts of the Ukraine's dismantlement of its nuclear weapons

  9. Perceived popularity of adolescents who use weapons in violence and adolescents who only carry weapons.

    2017-01-01

    Prior research has found that persistently delinquent youth or more violent youth were less popular than their less delinquent peers (Young, 2013). However, recent research has also found that weapon carrying is associated with being more popular in adolescence (Dijkstra et al., 2010). The present paper examines the perceived popularity of adolescents who carry weapons in comparison to those who both carry and use weapons in acts of violence or threatened violence. Data consist of two waves from the National Longitudinal Study of Adolescent to Adult Health. Analyses use OLS regression with lagged predictors. This paper found no differences in number of friends between weapon carriers and weapon users. However, among both male and female gang members, those who did not use or carry weapons (abstainers) named significantly fewer friends than weapon users. Among females, weapon abstainers both named and were named by significantly more people than weapon users. These differences were not observed for males. Implications of these results and directions for future research are discussed.

    'Some 35,000 nuclear weapons remain in the arsenals of the nuclear powers, with thousands still deployed on hair-trigger alert. Whatever rationale these weapons may once have had has long since dwindled. Political, moral, and legal constraints on actually using them further undermine their strategic utility without, however, reducing the risks of inadvertent war or proliferation. The objective of nuclear non-proliferation is not helped by the fact that the nuclear weapon States continue to insist that those weapons in their hands enhance security, while in the hands of others they are a threat to world peace. If we were making steady progress towards disarmament, this situation would be less alarming. Unfortunately, the reverse is true.' - United Nations Secretary-General Kofi Annan. 'Something is wrong with the nuclear disarmament and non-proliferation regime. Although seemingly well-equipped with an arsenal of legal and political mechanisms, such as the Nuclear Non-Proliferation Treaty (NPT), the 1996 Advisory Opinion of the International Court of Justice (ICJ), decades' worth of General Assembly (GA) resolutions and even a recent slew of ad-hoc, plurilateral initiatives such as the Proliferation Security Initiative, the regime created to prevent the catastrophe of nuclear war remains inadequate. This insufficiency is even starker when viewed in relation to the regimes controlling other weapons of mass destruction. Despite its own challenges, the Organization for the Prohibition on Chemical Weapons remains relatively well-funded and well-situated to facilitate the implementation of the Chemical Weapons Convention (CWC). Even the Biological and Toxin Weapons Convention (BTWC), while still lacking the necessary verification mechanisms, has managed to effectively criminalize not just the use and threat of use of biological weapons, but also their production, development and stockpiling. Meanwhile, the anti-nuclear regime seems to be faltering. Progress made in

    1958-10-01

    The program of the Atomic Energy Commission on environmental contamination from weapons tests is designed for the overall evaluation of the hazard to humans from test operations. It is limited to studies of the deposition of activity at long range rather than the problems associated with immediate, close-in fallout. The program has largely been a study of Sr{sup 90}, since considerations based on experience and measurement indicate that it is the isotope of greatest potential hazard. Data are presented pertinent to the monitoring of long-range fallout, particularly Sr{sup 90} and Cs{sup 137}. Values are tabulated for the fallout deposition, air concentrations, water concentrations, and the amounts in foods and human bone. In addition, results are given for some experimental investigations. The report of these results is not interpretative although certain papers that do attempt to interpret the present situation with respect to Sr{sup 90} in particular are reprinted. Bibliographies are presented covering the period since the 1957 hearings before the Joint Committee on Atomic Energy concerning the nature of radioactive fallout and its effects on man. A document list of submissions to the United Nations Scientific Committee on the Effects of Atomic Radiation is given to illustrate the work done in other countries. Several papers on the subject, which have not been generally available, are reprinted.

    In this study leading experts summarize the work of a working group meeting during several years, and they represent the state of the art of the international discussion about the non-proliferation of nuclear weapons. The technical basis of proliferation, the relations between energy policy and nuclear energy, as well as the development of the non-proliferation system up to the present are thoroughly studied. Special attention is paid to the further development of the instruments of the non-proliferation policy, and approaches and ways to improving the control of the fuel cycle, e.g. by means of multinational methods or by improving the control requirements are analyzed. Also the field of positive inducements and negative sanctions to prevent the proliferation as well as the question of ensured supply are elucidated in detail. A further section then analyzes the functions of the international organizations active in this field and the nuclear policy of the most important western industrial nations, the RGW-states and the threshold countries of the Third World. This volume pays special attention to the nuclear policy of the Federal Republic of Germany and to the possibilities and necessities of a further development of the non-proliferation policy. (orig.)

  17. Electroshock weapons can be lethal!

    2008-03-01

    Electroshock weapons (EWs)-stun guns, tasers, riot shields-are electroconductive devices designed to safely incapacitate healthy men neuromuscularly, so they are called nonlethal or less-lethal. EW firms seeking large nonmilitary markets targeted law enforcement and corrections personnel, who began using EWs in prisons/jails and on public patrol in 1980 in the USA. This shifted the EW-shocked population from healthy soldiers to a heterogeneous mix of both sexes, ages 6-92, in a wide variety of health conditions! An EW operates by disrupting normal physiological processes, producing transient effects in healthy people. But if a person's health is sufficiently compromised, the margin of safety can be lost, resulting in death or permanent health problems. 325 people have died after EW shock since 1980. Did the EW cause these deaths? Evidence indicates that EWs do play a causal role in most such deaths. EWs can be lethal for people in diabetic shock^1 (hypoglycemia), which may be why Robert Dziekanski-a Polish immigrant to Canada-died so quickly after he was tasered at Vancouver Airport: not having eaten for over 10 hours, he likely was severely hypoglycemic. The EW death rate in North America is 30 times higher than need be, because EW users have not been properly trained to use EWs on a heterogeneous population safely! ^1J.

    The Configurable Muon Tracker (CMT) is an adaptation of the existing drift tube detector commercially available from Decision Sciences International Corporation (DSIC). NSTec engineered the CMT around commercially available drift tube assemblies to make a detector that is more versatile than previous drift tube assemblies. The CMT became operational in February 2013. Traditionally, cosmic-ray muon trackers rely on near-vertical trajectory muons for imaging. Since there are scenarios where imaging using vertical trajectory muons is not practical, NSTec designed the CMT specifically for quick configurability to track muons from any trajectory. The CMT was originally designed to be changed from vertical imaging mode to horizontal imaging mode in a few hours with access to a crane or other lifting equipment. In FY14, locations for imaging weapon trainers and SNM were identified and it was determined that lifting equipment would not typically be available in experimental areas. The CMT was further modified and a portable lifting system was developed to allow reconfiguration of the CMT without access to lifting equipment at the facility. This system was first deployed at Los Alamos National Laboratory’s W-division, where several trainers were imaged in both horizontal and vertical modes. Real-time images have been compared in both modes showing that imaging can be done in both modes with the expected longer integration time for horizontal mode. Further imaging and post processing of the data is expected to continue into early FY15.

    The formidable task of restructuring the former Soviet Union's economic system depends largely on it success in converting a defense industry that once employed 11 million Soviet workers to peaceful pursuits, says Artiom Ustinov, a researcher in the U.S. and Canada Institute in Moscow. open-quotes Governments could convert defense facilities into those that develop and manufacture products that people desperately need and want,close quotes says Ustinov. Unfortunately, such a transformation cannot happen quickly because the former Soviet Union lacks a high-tech sector into which former weapons workers can migrate. An even more serious problem stems from a traditional isolation from world markets. Civilian manufacturing in the former Soviet Union, which was never forced to meet international standards for quality and performance, has been marked by inferior products. open-quotes With financial support, a well-defined program, incentives, and retraining, the military research labs could find themselves in a better position to release their huge potential for creative rather than destructive purposes,close quotes Ustinov concludes

    Among the some 170 sovereign states in the world, five are legally recognized as nuclear weapon states (NWS) under the terms of the 1968 Non-Proliferation Treaty (NPT). Six countries (Argentina, Brazil, India, Israel, Pakistan, and South Africa) are counted as threshold states: they possess sizeable unsafeguarded nuclear facilities or have passed the brink of a nuclear test or of clandestine weapon production. Six other countries (Iran, Iraq, Libya, Taiwan, and North and South Korea) have been suspected periodically of either considering the nuclear weapon option or of working secretly on the development of weapons. Thus, about 150 non-nuclear weapon states (NNWS) remain which neither possess nuclear weapons nor strive to acquire them. These states are distributed throughout the globe and encompass highly industrialized as well as underdeveloped countries, liberal democracies, socialist states, sheikdoms and dictatorships. Some NNWS face acute military threats; other are far removed from the quarrels of the world, as in the case of some remote fortunate islands. Furthermore, NNWS may be members of nuclear-umbrella alliances or may have opted for a policy of neutrality or non-alignment

    This article describes a brief history of chemical warfare, which culminated in the signing of the Chemical Weapons Convention. It describes the current level of chemical weapons and the risk of using them. Furthermore, some traditional technology for the development of chemical weapons, such as increasing toxicity, methods of overcoming chemical protection, research on natural toxins or the introduction of binary technology, has been described. In accordance with many parameters, chemical weapons based on traditional technologies have achieved the limit of their development. There is, however, a big potential of their further development based on the most recent knowledge of modern scientific and technical disciplines, particularly at the boundary of chemistry and biology. The risk is even higher due to the fact that already, today, there is a general acceptance of the development of non-lethal chemical weapons at a technologically higher level. In the future, the chemical arsenal will be based on the accumulation of important information from the fields of chemical, biological and toxin weapons. Data banks obtained in this way will be hardly accessible and the risk of their materialization will persist.

  2. China's mixed signals on nuclear weapons

    1991-01-01

    Ultimately, it is nuclear whether the Chinese leadership has made up its collective mind on practical nuclear weapons. It is known from Chinese official sources, including articles in Communist Party and military publications and histories of the Chinese nuclear program, that an internal debate has proceeded for more than two decades, punctuated by occasional nuclear exercises or low-yield warhead tests. But China presumably has less reason now to pursue development of tactical nuclear weapons than in previous decades: relations with the Soviet Union have improved and military confrontation has eased; China's relations with India and Vietnam are also improving. The decision may already have been made, however, and the weapons built. The mystery surrounding Chinese tactical nuclear weapons is itself interesting, but it is also symbolic of the difficulty of understanding China's nuclear weapons program and policies. The West has accumulated a considerable body of knowledge about China's nuclear forces, especially historical material. But important aspects of China's nuclear behavior and its future as a nuclear power are hard to discern. A key question is China's future role in the spread of nuclear-capable weapons to other countries. China might add to international efforts to stem the proliferation of nuclear related technology, or it might become the world's missile merchant. It could make a constructive contribution to arms control efforts in general, or it could act as a spoiler

  7. Nuclear Weapons in Russia's approach to conflict

    International Nuclear Information System (INIS)

    Johnson, Dave

    2016-11-01

    President Putin has moved nuclear weapons to the foreground of the European security landscape. New risks and dangers arise from the apparent coupling of nuclear weapons capabilities with Moscow's revanchist and irredentist foreign and defence policies toward its neighbours. Nuclear weapons are the central feature and capstone capability in Russia's evolving concept of strategic deterrence and are important tools for achieving Russia's geopolitical aims. Russian thinking on the role and place of nuclear weapons in upholding national security and in achieving strategic aims is reflected in military policy, force structure and posture, and exercises and operations. Russia's political and military leaders are not only re-conceptualising the role of nuclear weapons. They are also building the military capabilities that can credibly threaten the calibrated employment of nuclear weapons for deterrence, de-escalation and war-fighting from the regional to large-scale and global levels of conflict. New and still developing concepts for the employment of conventional long-range precision weapons in tandem with nuclear weapons for regional deterrence and containment of local and regional conflicts add volatility to the regional tensions and uncertainties created by recent Russian aggression. Russia's reliance upon integrated conventional and nuclear capabilities in reasserting its influence in its perceived sphere of special interest, intended to contain conflicts at a manageable level, could actually increase the risk of the potential employment of nuclear weapons. NATO nations collectively, and the three NATO nuclear powers (Great Britain, France, and the United States) individually, have recognized this new reality and have begun to adapt to it. In that context, the aim of this paper is to elaborate a clearer understanding of the place and role of nuclear weapons in Russia's approach to conflict, based on nuclear-related policy statements and military-theoretical writing

  9. Vulnerability assessment of a space based weapon platform electronic system exposed to a thermonuclear weapon detonation

    Science.gov (United States)

    Perez, C. L.; Johnson, J. O.

    Rapidly changing world events, the increased number of nations with inter-continental ballistic missile capability, and the proliferation of nuclear weapon technology will increase the number of nuclear threats facing the world today. Monitoring these nation's activities and providing an early warning and/or intercept system via reconnaissance and surveillance satellites and space based weapon platforms is a viable deterrent against a surprise nuclear attack. However, the deployment of satellite and weapon platform assets in space will subject the sensitive electronic equipment to a variety of natural and man-made radiation environments. These include Van Allen Belt protons and electrons; galactic and solar flare protons; and neutrons, gamma rays, and x-rays from intentionally detonated fission and fusion weapons. In this paper, the MASH vl.0 code system is used to estimate the dose to the critical electronics components of an idealized space based weapon platform from neutron and gamma-ray radiation emitted from a thermonuclear weapon detonation in space. Fluence and dose assessments were performed for the platform fully loaded, and in several stages representing limited engagement scenarios. The results indicate vulnerabilities to the Command, Control, and Communication bay instruments from radiation damage for a nuclear weapon detonation for certain source/platform orientations. The distance at which damage occurs will depend on the weapon yield (n,(gamma)/kiloton) and size (kilotons).

  10. Combating the terrorist use of mass destruction weapons, particularly nuclear weapons

    The risks of mass destruction weapons vary and also forms of damages resulting therefrom. While the effects of nuclear weapons are focused, sudden and comprehensive, the chemical weapons have limited impacts relatively unless used intensively severe prejudice to the element of surprise, and thus impaired the efficacy of their influences,especially that they affect exceptionally the individuals in the area of injury and biological weapons do not announce themselves except through their effect that appears later than the time of use as they affect exceptionally the organisms in the area of injury.The mass destruction weapons have turned from being a purely military means in the early twentieth century and have now become the means of violence against governments and countries that they should prepare themselves for and respond in ways of successful and effective countermeasures. Despite the fact that the acquisition of mass destruction weapons can be considered as a priority objective, which terrorist groups and organizations steadily seek but their accessibility is flanked by a lot of difficulties. Addressing the risk of further spread of nuclear weapons, and especially after doubling the power of those high-risk weapons, the international community has an approach to take a number of arrangements that complement each other to control and resist nuclear proliferation, either for the states or for terrorist groups.

    2012-01-01

    Full Text Available This paper analyzed the conditions for the occurrence of corrosion processes on historically important weapons and military equipment made of steel during the period in outdoor environment. A considerable attention has been given to the characteristics of the most important corrosion products formed on the steel surface. The formation of akaganite, β-FeOOH is a sign of active corrosion under a layer of corrosion products. The conditions that cause the formation and regeneration of hydrochloric and sulphuric acid during the exposure to the elements were analyzed. The most often applied methods of diagnostics and procedures of removing active corrosion anions (desalination were described as well. The NaOH solution of certain pH values still has the most important application for the desalination process. The procedures for cleaning the surface before the application of protective coatings and the application of chemicals that transform rust into stable compounds were discussed. As protective coatings, different types of organic coatings plated on well-prepared steel surfaces were used and sometimes special types of waxes as well. This paper presents the results of the tests of corrosion products taken from the exhibits of weapons and military equipment from the Military Museum in Belgrade.

    Zero-phonon lines have been registered in photoluminescence spectra of near-surface layer radiation color centers in lithium fluoride nanocrystals. They have been assigned to transitions of the definite types centers. The frequencies of phonons participating in the transitions of the different type centers located both in the near-surface layer and in the crystal bulk have been measured and compared. The Huang-Rhys parameters for the transitions of these centers have been determined. It has been found that the Huang-Rhys parameters for the studied transitions in the near-surface layer centers of the certain composition are less than for those in the crystal bulk centers of the same composition. This feature is connected with the difference of the electron density distribution in defects. Temperature dependences of the zero-phonon lines widths and shifts have been measured. It has been determined that both widths and shifts grow faster with the increase of a temperature for the defects transitions with the lesser Huang-Rhys parameters. Phonons lifetimes are estimated from the experimental data.

  14. Does nuclear power lead to nuclear weapons

    International Nuclear Information System (INIS)

    Prawitz, J.

    1977-01-01

    It is pointed out that 'reactor grade' plutonium usually contains about 30 % Pu240 and is unsuitable for weapons. While it is possible to obtain an explosion, it is more difficult to initiate one and its effect, which will be considerably less than with bomb grade plutonium, is difficult to predict. The critical mass will be larger and more cooling required. The proliferation problem is then discussed and the four aspects, vertical, horizontal, sub-national and revolutionary, mentioned. In connection with nuclear power it is the second and third aspects which are of interest. In discussing the possibility of terrorist groups obtaining plutonium, a study by the Swedish Defence Research Institute is quoted as estimating that 10-20 qualified specialists and several years secret preparation would be necessary to make a nuclear weapon. Other authors, e.g. Ted Taylor, have maintained that it would be much easier, but examples of 'student designs' are primitive and unlikely to detonate. Even so, it is emphasised that safeguards and physical security are necessary. Horizontal proliferation is a more real problem and the NPT and IAEA safeguards are discussed in this connection. In conclusion the question of whether the proliferation of nuclear weapons via nuclear power can be prevented cannot be answered with a clear yes or no. Certain states may use nuclear weapon potential as a bargaining factor. However the decision to acquire nuclear weapons is political and while a nuclear power industry would be of help, it would not be decisively so. (JIW)

    Whether he intended it or not, Bush has taken steps that mean the beginning of the end for nuclear weapons. His proposals significantly reduce the numbers of nuclear weapons and the burdens associated with deploying and controlling them. And although he retains many of the options for continuing and regenerating the nuclear arsenal, he has exposed the fact that there are no longer any grand justifications or doctrinal needs for nuclear weapons - and that the nuclear machine is choking on its economic, political, environmental, and human contradictions. The initiatives fundamentally altered the nuclear stance of both nations. Yet, as momentous as the changes were, they were set in motion in an almost businesslike manner. Neither leader truly framed the moves as an end to the nuclear age. But they didn't need to. The steps they have taken practically guarantee it

  17. Prions: the danger of biochemical weapons

    Directory of Open Access Journals (Sweden)

    Eric Almeida Xavier

    2014-09-01

    Full Text Available The knowledge of biotechnology increases the risk of using biochemical weapons for mass destruction. Prions are unprecedented infectious pathogens that cause a group of fatal neurodegenerative diseases by a novel mechanism. They are transmissible particles that are devoid of nucleic acid. Due to their singular characteristics, Prions emerge as potential danger since they can be used in the development of such weapons. Prions cause fatal infectious diseases, and to date there is no therapeutic or prophylactic approach against these diseases. Furthermore, Prions are resistant to food-preparation treatments such as high heat and can find their way from the digestive system into the nervous system; recombinant Prions are infectious either bound to soil particles or in aerosols. Therefore, lethal Prions can be developed by malicious researchers who could use it to attack political enemies since such weapons cause diseases that could be above suspicion.

    Both the United States and Russia are retaining as strategic reserves more plutonium and HEU for potential reuse as weapons, than is legitimately needed. Both have engaged in discussions and have programs in various stages of development to dispose of excess plutonium and HEU. These fissile material disposition programs will take decades to complete. In the interim there will be, as there is now, hundreds of tons of separated weapon-usable fissile material stored in tens of thousands of transportable canisters, each containing from a few to several tons of kgs of weapon-usable fissile material. This material must be secured against theft and unauthorized use. To have high confidence that the material is secure, one must establish criteria against which the adequacy of the protective systems can be judged. For example, one finds such criteria in US Nuclear Regulatory Commission (USNRC) regulations for the protection of special nuclear materials

It describes the medical consequences of the effects of blast, heat and ionizing radiation from nuclear weapons, including details from the Hiroshima and Nagasaki atomic bombings. The medical consequences of a nuclear attack including consideration of the casualties, care of the injured, psychological effects and the outcome are also discussed. It is concluded that if for none other than purely medical reasons, nuclear warfare must never be allowed to happen. (UK)

    Only nuclear explosions near or above the earth's surface or under water have contributed substantial amounts of transuranic materials to the world bioenvironment. The amounts of transuranics placed in the environment through underground test ventings, accidents involving US nuclear weapons, and releases during weapon production operations have been negligible in comparison with those from atmospheric testing of nuclear explosives. On the order of 10 5 Ci of plutonium has been dispersed within our environment from about 400 nuclear explosive tests, including those by the US, Great Britain, and Russia, between 1945 and 1963, plus more recent nuclear explosive tests in the atmosphere by China, India, and France

    1993-01-01

    Between 1952 and 1958 Britain conducted five separate nuclear weapons trials in Australia. Australia had the uninhabited wide open spaces and the facilities which such tests need and Britain was able to use its special relationship with Australia to get agreement to conduct atomic tests in Australia and establish a permanent test site at Maralinga. Other non-nuclear tests were conducted between 1953-1963. The story of Britain's involvement in atomic weapons testing in Australia is told through its postal history. Both official and private covers are used to show how the postal communications were established and maintained throughout the test years. (UK)

    Reasons for India's total ban on the export of rhesus monkeys to U.S. have been explained. The major reason is that some of the animals were used in nuclear weapon related radiation experiments. This was a clear violation of a stricture in the agreement about supply of monkeys. The stricture prohibited the use of animals for research concerning military operations, including nuclear weapon testing. It is pleaded that a strict enforcement of strictures rather than a total ban on the export of monkeys would be better in the interest of advancement of knowledge in human medicine and disease control.

    The alteration of a knee immobilizer into a sharp weapon by a prisoner prompted us to survey neighboring penal institutions to determine the frequency of such events. We mailed a nine-item survey to all detention facilities in Tennessee, Arkansas, and Mississippi. A second survey was sent to nonresponding institutions 6 weeks after the initial mailing. The Regional Medical Center at Memphis, the designated facility for evaluation and treatment of prisoners from the county jail and state penitentiary. Survey respondents included 25 state penitentiaries, 31 county jails, 1 state minimum-security facility, 1 state maximum-security facility, 1 work-release center, 1 county detention center for drunken-driving offenders, and 1 federal penitentiary. Of the 81 institutions surveyed, 77% responded to one of the two mailings. Forty percent responded in the affirmative when asked whether stolen or unauthorized medical equipment from outside their institutions had been discovered among inmates. When respondents were questioned as to whether medical equipment, prescribed or not, had been used or altered in a criminal manner, 34% responded "yes." Medications and medical appliances were listed in the responses. A survey of 81 local and neighboring penal institutions in a three-state area revealed that the illicit use of medicine and medical devices by prisoners is a legitimate safety concern of prison personnel and health care workers when medical care for inmates must be sought outside the security of their institutions. The modification of medical equipment into weapons by incarcerated patients, although clearly recognized as a security and safety problem by police authorities, appears to be unappreciated by health care workers providing episodic care to inmates.

    In 1993, as the CWC ratification process was beginning, concerns arose that the complexity of integrating the CWC with national law could cause each nation to implement the Convention without regard to what other nations were doing, thereby causing inconsistencies among States as to how the CWC would be carried out. As a result, the author's colleagues and the author prepared the Manual for National Implementation of the Chemical Weapons Convention and presented it to each national delegation at the December 1993 meeting of the Preparatory Commission in The Hague. During its preparation, the Committee of CWC Legal Experts, a group of distinguished international jurists, law professors, legally-trained diplomats, government officials, and Parliamentarians from every region of the world, including Central Europe, reviewed the Manual. In February 1998, they finished the second edition of the Manual in order to update it in light of developments since the CWC entered into force on 29 April 1997. The Manual tries to increase understanding of the Convention by identifying its obligations and suggesting methods of meeting them. Education about CWC obligations and available alternatives to comply with these requirements can facilitate national response that are consistent among States Parties. Thus, the Manual offers options that can strengthen international realization of the Convention's goals if States Parties act compatibly in implementing them. Equally important, it is intended to build confidence that the legal issues raised by the Convention are finite and addressable.

  7. Nuclear Weapons Enterprise Transformation - A Sustainable Approach

    International Nuclear Information System (INIS)

    O'Brien, K H

    2005-01-01

    Nuclear weapons play an essential role in United States (U.S.) National Security Policy and a succession of official reviews has concluded that nuclear weapons will continue to have a role for the foreseeable future. Under the evolving U.S. government policy, it is clear that role will be quite different from what it was during the Cold War. The nuclear-weapons stockpile as well as the nuclear-weapons enterprise needs to continue to change to reflect this evolving role. Stockpile reductions in the early 1990s and the Stockpile Stewardship Program (SSP), established after the cessation of nuclear testing in 1992, began this process of change. Further evolution is needed to address changing security environments, to enable further reductions in the number of stockpiled weapons, and to create a nuclear enterprise that is cost effective and sustainable for the long term. The SSP has successfully maintained the U.S. nuclear stockpile for more than a decade, since the end of nuclear testing. Current plans foresee maintaining warheads produced in the 1980s until about 2040. These warheads continue to age and they are expensive to refurbish. The current Life Extension Program plans for these legacy warheads are straining both the nuclear-weapons production and certification infrastructure making it difficult to respond rapidly to problems or changes in requirements. Furthermore, refurbishing and preserving Cold-War-era nuclear weapons requires refurbishing and preserving an infrastructure geared to support old technology. Stockpile Stewardship could continue this refurbishment approach, but an alternative approach could be considered that is more focused on sustainable technologies, and developing a more responsive nuclear weapons infrastructure. Guided by what we have learned from SSP during the last decade, the stewardship program can be evolved to address this increasing challenge using its computational and experimental tools and capabilities. This approach must start

    The U.S. Army Fort Irwin National Training Center (NTC), in the Mojave Desert, obtains all of its potable water supply from three groundwater basins (Irwin, Langford, and Bicycle) within the NTC boundaries (fig. 1; California Department of Water Resources, 2003). Because of increasing water demands at the NTC, the U.S. Geological Survey (USGS), in cooperation with the U.S. Army, completed several studies to evaluate water resources in the developed and undeveloped groundwater basins underlying the NTC. In all of the developed basins, groundwater withdrawals exceed natural recharge, resulting in water-level declines. However, artificial recharge of treated wastewater has had some success in offsetting water-level declines in Irwin Basin. Additionally, localized water-quality changes have occurred in some parts of Irwin Basin as a result of human activities (i.e., wastewater disposal practices, landscape irrigation, and/or leaking pipes). As part of the multi-faceted NTC-wide studies, traditional datacollection methods were used and include lithological and geophysical logging at newly drilled boreholes, hydrologic data collection (i.e. water-level, water-quality, aquifer tests, wellbore flow). Because these data cover a small portion of the 1,177 square-mile (mi2 ) NTC, regional mapping, including geologic, gravity, aeromagnetic, and InSAR, also were done. In addition, ground and airborne electromagnetic surveys were completed and analyzed to provide more detailed subsurface information on a regional, base-wide scale. The traditional and regional ground and airborne data are being analyzed and will be used to help develop preliminary hydrogeologic framework and groundwater-flow models in all basins. This report is intended to provide an overview of recent water-resources and land-surface deformation studies at the NTC.

    The volume contains, in addition to an introduction into the matter, the texts of the Foreign Trade Act (FTA), the War Weapons Control Act and all relevant ordinances. Foreign trade transactions of the Federal Republic of Germany are essentially, but not exclusively, governed by the FTA. They are strongly influenced by the legislation of the European Communities which in the form of directives are immediately effective here, and in the form of guidelines oblige the German lawgiver or ordinance giver to translate them into practice, mostly by appropriate modifications of the foreign trade ordinance, the import and export lists. It is not the war weapons which are the problem, but the so-called dual-use goods, namely articles, technologies and knowledge which, as a rule, serve civil purposes, which, however, may be used also to produce weapons, in particular ABC weapons or rockets. Nowadays we are concerned about several third-world states which are obsessed by the wish to build their own atomic bomb. (orig./HSCH) [de

  18. The Spear: An Effective Weapon Since Antiquity

    Directory of Open Access Journals (Sweden)

    Robert E. Dohrenwend

    2012-07-01

    Full Text Available The spear is perhaps man’s oldest weapon, and may even be his oldest tool. Over the hundreds of thousands of years of the weapon’s existence, it evolved from a pointed stick into an efficient hunting missile, and then became the most effective hand-held bladed weapon humans ever devised. The spear and its use is the only martial art originally devised for use against species other than our own, and more than any other weapon, the spear emphasizes the relationship between hunting and warfare. Virtually without exception, the spear is present wherever there are humans. The spear may claim to be the senior martial art, and the weapon is still in use today. Early techniques are preserved by the small number of Japanese sojutsu schools, and modern Chinese martial artists have developed elegant and impressive gymnastic routines for the spear. The javelin throw is a modern Olympic track and field event, and there are people who have resurrected the Aztec atlatl for sporting competition. Today, the spear is still used in Europe for hunting wild boar, and the continued issue of the obsolete bayonet to modern soldiers testifies to a deep, almost instinctive respect still possessed by the military for the spear.

  19. Burning weapons-grade plutonium in reactors

    International Nuclear Information System (INIS)

    Newman, D.F.

    1993-06-01

    As a result of massive reductions in deployed nuclear warheads, and their subsequent dismantlement, large quantities of surplus weapons- grade plutonium will be stored until its ultimate disposition is achieved in both the US and Russia. Ultimate disposition has the following minimum requirements: (1) preclude return of plutonium to the US and Russian stockpiles, (2) prevent environmental damage by precluding release of plutonium contamination, and (3) prevent proliferation by precluding plutonium diversion to sub-national groups or nonweapons states. The most efficient and effective way to dispose of surplus weapons-grade plutonium is to fabricate it into fuel and use it for generation of electrical energy in commercial nuclear power plants. Weapons-grade plutonium can be used as fuel in existing commercial nuclear power plants, such as those in the US and Russia. This recovers energy and economic value from weapons-grade plutonium, which otherwise represents a large cost liability to maintain in safeguarded and secure storage. The plutonium remaining in spent MOX fuel is reactor-grade, essentially the same as that being discharged in spent UO 2 fuels. MOX fuels are well developed and are currently used in a number of LWRs in Europe. Plutonium-bearing fuels without uranium (non-fertile fuels) would require some development. However, such non-fertile fuels are attractive from a nonproliferation perspective because they avoid the insitu production of additional plutonium and enhance the annihilation of the plutonium inventory on a once-through fuel cycle

    1997-09-01

    The objective of finding nuclear material at entry portals is to provide a secure perimeter as large as a weapon damage radius so that operations could be conducted within it relatively unencumbered. The objective of wide area search for nuclear material to provide a safe zone of similar dimensions in an area in which it is not possible to maintain a secure perimeter, to provide assurance for civilians living at an area at risk, or to provide rapid, wide area search of regions that could conceal nuclear threats to forces in the field. This rapid, wide-area, and confident detection of nuclear materials is the essential first step in developing the ability to negate terrorist nuclear assemblies or weapons. The ability to detect and negate nuclear materials are necessary to prevent the forced, massive evacuation of urban populations or the disruption of military operations in response to terrorist threats. This paper describes the limitations to current sensors used for nuclear weapon detection and discusses a novel approach to nuclear weapon detection using a combination of directional information (imaging) and gamma ray energy (color) to produce a gamma ray color camera

    Full Text Available Drilling is one of the most useful metal cutting processes and is used in various applications, such as aerospace, electronics, and automotive. In traditional drilling methods, the thrust force, torque, tolerance, and tribology (surface roughness are related to the cutting condition and tool geometry. In this paper, the effects of a pre-center drill hole, tool material, and drilling strategy (including continuous and non-continuous feed on thrust force, surface roughness, and dimensional accuracy (cylindricity have been investigated. The results show that using pre-center drill holes leads to a reduction of the engagement force and an improvement in the surface quality and cylindricity. Non-continuous drilling reduces the average thrust force and cylindricity value, and High Speed Steels HSS-Mo (high steel speed + 5–8% Mo reduces the maximum quantity of cutting forces. Moreover, cylindricity is directly related to cutting temperature and is improved by using a non-continuous drilling strategy.

  7. The risk of nuclear weapons proliferation

    International Nuclear Information System (INIS)

    Oelgaard, P.L.

    1994-01-01

    During the later years the risks of nuclear proliferation have again become a major topic of interest. This is primarily due to the acute problems caused by Iraq, North Korea, and the 3 new states of the former USSR, Ukraine, Kazakhstan and Belarus. Analysis shows that security problems and prestige are the two most important motives, when the risks of proliferation are considered. But motives are not enough. To produce nuclear weapons a number of technological requirements must also be fulfilled. The country must be able to produce almost pure fissile material, i.e. 235 U or 239 Pu. It must also be able to solve a number of metallurgical, explosive, ignition, physics and other problems. These are in particular non-trivial, if a implosion weapon is to be designed. A review is made of the nuclear facilities in a number of the countries which have been suggested as possible future nuclear weapons countries. In particular facilities which can produce almost pure fissile materials, 235 U and 239 Pu, are considered. The possibility of nuclear terrorists have often been discussed in the media. However, it seems very unlikely that even a major terrorist or mafia organization will be able to solve all the weapons design problems, even if they could steal the fissile material. It is finally discussed what can be done to reduce the risk of further nuclear proliferation. Political pressure can be brought to bear on countries outside the NPT to join it, but it can be counter-productive, and sometimes the countries that are able to exert such pressure, are not willing to do so for other political reasons. The problem of countries which are party to the NPT, but which are believed to acquire nuclear weapons capability in violation of the treaty, can be countered by unannounced inspections of non-declared facilities. However, such inspections can only be meaningfully performed if the necessary intelligence is available. (EG)

    Drotning, W.; Wapman, W.; Fahrenholtz, J.

    1993-01-01

    Robotic systems are being developed by the Intelligent Systems and Robotics Center at Sandia National Laboratories to perform automated handling tasks with radioactive weapon parts. These systems will reduce the occupational radiation exposure to workers by automating operations that are currently performed manually. The robotic systems at Sandia incorporate several levels of mechanical, electrical, and software safety for handling hazardous materials. For example, tooling used by the robot to handle radioactive parts has been designed with mechanical features that allow the robot to release its payload only at designated locations in the robotic workspace. In addition, software processes check for expected and unexpected situations throughout the operations. Incorporation of features such as these provides multiple levels of safety for handling hazardous or valuable payloads with automated intelligent systems

    Russell, G.J.; Seeger, P.A.; Fluharty, R.G.

    1977-03-01

    Parametric studies, using continuous-energy Monte Carlo codes, were done to optimize the neutronics of the Weapons Neutron Research (WNR) target and three possible target/moderator configurations: slab target/slab moderators, cylindrical target/cylindrical moderator, and cylindrical target/double-wing moderators. The energy range was 0.5 eV to 800 MeV. A general figure-of-merit (FOM) approach was used. The WNR facility performance can be doubled or tripled by optimizing the target and target/moderator configurations; this approach is more efficient than increasing the Clinton P. Anderson Meson Physics Facility (LAMPF) accelerator power by an equivalent factor. A bare target should be used for neutron energies above approximately 100 keV. The FOM for the slab target/slab moderator configuration is the best by a factor of at least 2 to 3 below approximately 1 keV. The total neutron leakage from 0.5 eV to 100 keV through a 100- by 100-mm area centered at the peak leakage is largest for the slab moderator, exceeding that of the cylindrical moderator and double-wing moderator by factors of 1.7 and 3.4, respectively. The neutron leakage at 1 eV from one 300- by 150-mm surface of a slab moderator is 1.5 times larger than that from one 155- by 150-mm surface of a cylindrical moderator. When compared with the 1-eV leakage from two 100- by 150-mm surfaces of a double-wing moderator, that from the slab moderator is 3.4 times larger. 107 figures, 13 tables

    Full Text Available The Terracotta Army of the First Emperor of China is one of the most emblematic archaeological sites in the world. Many questions remain about the logistics of technology, standardisation and labour organisation behind the creation of such a colossal construction in just a few decades over 2,000 years ago. An ongoing research project co-ordinated between the UCL Institute of Archaeology and the Emperor Qin Shihang's Terracotta Army Museum is beginning to address some of these questions. This paper outlines some results of the typological, metric, microscopic, chemical and spatial analyses of the 40,000 bronze weapons recovered with the Terracotta Warriors. Thanks to a holistic approach developed specifically for this project, it is possible to reveal remarkable aspects of the organisation of the Qin workforce in production cells, of the standardisation, efficiency and quality-control procedures employed, and of the sophisticated technical knowledge of the weapon-makers.

    The potential for chemical weapons to be used in terrorism is a real possibility. Classes of chemical weapons include nerve agents, vesicants (blister agents), choking agents, incapacitating agents, riot control agents, blood agents, and toxic industrial chemicals. The nerve agents work by blocking the actions of acetylcholinesterase leading to a cholinergic syndrome. Nerve agents include sarin, tabun, VX, cyclosarin, and soman. The vesicants include sulfur mustard and lewisite. The vesicants produce blisters and also damage the upper airways. Choking agents include phosgene and chlorine gas. Choking agents cause pulmonary edema. Incapacitating agents include fentanyl and its derivatives and adamsite. Riot control agents include Mace and pepper spray. Blood agents include cyanide. The mechanism of toxicity for cyanide is blocking oxidative phosphorylation. Toxic industrial chemicals include agents such as formaldehyde, hydrofluoric acid, and ammonia.

    Following a brief historical introduction the concept of proliferation, vertical horizontal and subnational, is presented, and its relationship to nuclear power discussed. The risk of nuclear weapon proliferation, based on political decision, motivation and costs, is related to access to enriched uranium, plutonium and uranium 233. The possibilities for diversion and theft from nuclear facilities are discussed. International measures to prevent proliferation, the Non-Proliferation Treaty (NPT)and the IAEA safeguards system, are described and discussed. Measures which may be enacted against countries which break the NPT are discussed. Restrictions on international nuclear trude, both multilateral and unilateral, are also discussed, especially those at present, or shortly to be, enforced by USA, Canada and Australia. The International Nuclear Feel Cycle Evaluation (INFCE) is briefly presented. The physical protection of nuclear materials is also discussed. Finally the basc principles of nuclear weapons are briefly presented. (JIW)

    It is unlikely that anybody would imagine the route to a nuclear-weapon-free world as a straight and unimpeded one. At the moment, there is a fading interest in the possibility of the concerted bilateral reduction of the US and Russian nuclear weapon stockpiles. The reason is evident: these powers demonstrate quite different approaches to two large political campaigns initiated in American political circles, namely NATO expansion to the East, and the attack on Anti-Ballistic-Missile (ABM) Treaty. Russia considers these initiatives as provocative in content and high-handed in the form. The West argues that Russian response is unjustified and insists on the peaceful nature of its plans?

    Nuclear weapons occupy a paradoxal place both in the collective imagination and in the historical reality: on the one hand everybody dreads the apocalypse horror, and on the other hand, dissuasion appears as an unchanging and quite comfortable situation. However, the world has become multipolar in this domain as well. The geopolitical map is reconstructing. Doctrinal revisions, initiatives against nuclear weapons proliferation, and nuclear disarmament measures are now on the agenda. The best foreign and French experts examine for the first time the consequences of these evolutions. They analyse in particular the split up risks and the potential consequences of a nuclear conflict in regions where atomic arms have become a key-component of the strategic landscape: Middle-Est, Far-East, Southern Asia. The choices France and its allies will have to face are examined as well. (J.S.)

    1978-01-01

    The theme of Dr. Marshall's lecture was that it is, from the viewpoint of prevention of proliferation of nuclear weapons,preferable to use plutonium as a fuel in FBR reactors rather than store it in what, in effect, would be plutonium mines. The true threat of proliferation lies in uranium enrichment. The FBR reactor is misunderstood and the US policy is not against breeders as such. Safeguards against the misuse of plutonium by leaving a residue of radioactivity after reprocessing is quite feasible, despite certain practical problems and extra costs. Weapon proliferation is subject to political objectives and intentions. Definite proposals are, (a) a limited number of reprocessing centres, (b) an accelerated development of FBR reactors, (c) a new FBR fuel cycle, (d) stop storage of spent thermal reactor fuel, (e) reinforced safeguards.

    Military descentralization of Latin America will constitute a measure that will keep its peoples from squandering in nuclear weapons out of their limited resources and will protect them from eventually being attacked in such fashion within their territories. This constitutes a considerable contribution award avoiding proliferation of nuclear weapons as well as a giant step towards general and complete disarmament. It will also constitute evidence that Latin America, faithful to its universalist tradition, not only must make a greater effort towards proscribing from its territories the treat of a nuclear war, but also must use all its resources to persevere in its struggle for welfare and progress of its peoples, cooperating along with the rest of the world to achieve the ideals of mankind as a whole

    Building on recent work in uncertainty quanti cation, we examine the use of imprecise probability methods to better characterize expert knowledge and to improve on misleading aspects of Bayesian analysis with informative prior distributions. Quantitative approaches to incorporate uncertainties in weapons certi cation are subject to rigorous external peer review, and in this regard, certain imprecise probability methods are well established in the literature and attractive. These methods are illustrated using experimental data from LANL detonator impact testing.

    Properties of Po-210 make it possible for its use as weapon of mass destruction. Po-210 occurs naturally in minute quantities in the human body, in Uranium ore (< 0.1 mg Po-210 / ton ) and as a product of Radon-222 gas decay chain. Po-210 also occurs as deposition on vegetation (tobacco leaves). Po-210 is produced by bombardment of Bi-209 with neutrons in a nuclear reactor. Russia produces 8 grams per year for export to USA market

    Response to the public health threat posed by nuclear weapons is a medical imperative. The United States, in contrast to other nations, has chosen a course that assures maximal casualties in the event of a nuclear attack, on the theory that prevention of the attack is incompatible with preventive measures against its consequences, such as blast injuries and radiation sickness. A decision analysis approach clarifies the risks and benefits of a change to a strategy of preparedness

  10. The US nuclear weapon infrastructure and a stable global nuclear weapon regime

    Energy Technology Data Exchange (ETDEWEB)

    Immele, John D [Los Alamos National Laboratory; Wagner, Richard L [Los Alamos National Laboratory

    2009-01-01

    US nuclear weapons capabilities -- extant force structure and nuclear weapons infrastructure as well as declared policy -- influence other nations' nuclear weapons postures, at least to some extent. This influence can be desirable or undesirable, and is, of course, a mixture of both. How strong the influence is, and its nature, are complicated, controversial, and -- in our view -- not well understood but often overstated. Divergent views about this influence and how it might shape the future global nuclear weapons regime seem to us to be the most serious impediment to reaching a national consensus on US weapons policy, force structure and supporting infrastructure. We believe that a paradigm shift to capability-based deterrence and dissuasion is not only consistent with the realities of the world and how it has changed, but also a desirable way for nuclear weapon postures and infrastructures to evolve. The US and other nuclear states could not get to zero nor even reduce nuclear arms and the nuclear profile much further without learning to manage latent capability. This paper has defined three principles for designing NW infrastructure both at the 'next plateau' and 'near zero.' The US can be a leader in reducing weapons and infrastructure and in creating an international regime in which capability gradually substitutes for weapons in being and is transparent. The current 'strategy' of not having policy or a Congressionally-approved plan for transforming the weapons complex is not leadership. If we can conform the US infrastructure to the next plateau and architect it in such a way that it is aligned with further arms reductions, it will have these benefits: The extant stockpile can be reduced in size, while the smaller stockpile still deters attack on the US and Allies. The capabilities of the infrastructure will dissuade emergence of new challenges/threats; if they emerge, nevertheless, the US will be able to deal with them in

  11. Western Option - Disarmament of Russian Weapon Plutonium

    International Nuclear Information System (INIS)

    Tveiten, B.; Petroll, M.R.

    2002-01-01

    The Western Option concept describes an approach to the conversion of weapon-grade plutonium from Russian nuclear warheads under the special aspects of meeting the criteria of irreversible utilization. Putting this concept of plutonium conversion into non-weapon-grade material into effect would make a major contribution to improving security worldwide. This study is based on an agreement between the Russian Federation and the United States of America concluded in September 2000. It provides for the conversion of 34 t of weapon-grade plutonium in each of the two states. This goal is also supported by other G8 countries. While the United States performs its part of the agreement under its sole national responsibility, the Russian program needs financial support by Western states. Expert groups have pointed out several options as a so-called basic scenario. The funds of approx. US Dollar 2 billion required to put them into effect have not so far been raised. The Western Option approach described in this contribution combines results of the basic scenario with other existing experience and with technical solutions available for plutonium conversion. One of the attractions of the Western Option lies in its financial advantages, which are estimated to amount to approx. US Dollar 1 billion. (orig.) [de

    During the turbulant transitional events in world politics in the nineties, the control of nuclear weapons plays a major role. While the superpowers are reducing their nuclear arsenal, the danger of nuclear anarchy in the world remains virulent. The NPT of 1968 is up for review soon. The falling apart of the former communist sphere of power, and the regions of conflict in the Third World present new risks for the proliferation of nuclear arms. For unified Germany, which explicitly renounced nuclear weapons, this situation presents difficult questions concerning national safety policies and international responsibility. This volume presents contributions which take a new look at topical and long-term problems of nuclear NP politics. The authors evaluate the conditions under which the NP regime came into being, and assess short- and long-term possibilities and risks. The following papers are included: 1.) Basic controversies during the negotiations concerning the Treaty on non-proliferation of nuclear weapons (Ungerer); 2.) Prologation of the NPT 1995 and appropriate problems concerning safety and control (Haefele/Lauppe); 3.) Consequences of the Iraq case for NP policy (Ficher); 4.)

  13. Nuclear weapons and the World Court ruling

    International Nuclear Information System (INIS)

    Singh, J.

    1998-01-01

    based on the initiatives by non-governmental organizations, the World Health Organisation (WHO) Assembly asked the International Court of Justice for an advisory opinion in 1993 whether, considering the environmental and health consequences, the use of nuclear weapons by a state in war or other armed conflict would be a breach of its obligations under international law. The World Court decided that it was not able to give an advisory opinion as requested, because of the fact that questions of use of force and such like were beyond the scope of specialized agencies like the WHO. The Court has ruled that the international community, especially the five nuclear weapon states have not only an obligation to negotiate a treaty for total nuclear disarmament, but also have an obligation to conclude such treaty. We may expect that the nuclear weapon states will cynically disregard the ruling of the World Court as they have been doing to the basic obligation itself in pursuit of nuclear hegemony. But the remaining 150 countries or so also bear a responsibility to keep nudging the recalcitrant states into implementing their commitments to disarm

  14. The German Debate on Tactical Nuclear Weapons

    2008-01-01

    This report analyses the debate in Germany about tactical nuclear weapons deployments in Europe. It is mainly based on interviews conducted with senior officials from the German Federal Foreign Ministry, the Federal Ministry of Defence, senior members of Parliament as well as experts from research institutes and think-tanks. The interviews focused on the more recent past in the German debate as well as the future of tactical nuclear weapon deployments in Germany and Europe. The report concludes that while a change of Germany's position on tactical nuclear weapons is unlikely to change in the short-term, several developments will make it unlikely that the continued involvement of Germany in NATO nuclear sharing will have to be debated in the medium term. Should the next Parliamentary elections, which will take place in 2009 at the latest, result in a Social Democrat-led government, a push for a reduction of Germany's involvement in NATO nuclear sharing appears possible. A conservative-led government is likely to maintain the nuclear status quo within NATO

  15. The Chemical Weapons Convention -- Legal issues

    Energy Technology Data Exchange (ETDEWEB)

    1997-08-01

    The Chemical Weapons Convention (CWC) offers a unique challenge to the US system of constitutional law. Its promise of eliminating what is the most purely genocidal type of weapon from the world`s arsenals as well as of destroying the facilities for producing these weapons, brings with it a set of novel legal issues. The reservations about the CWC expressed by US business people are rooted in concern about safeguarding confidential business information and protecting the constitutional right to privacy. The chief worry is that international verification inspectors will misuse their power to enter commercial property and that trade secrets or other private information will be compromised as a result. It has been charged that the Convention is probably unconstitutional. The author categorically disagrees with that view and is aware of no scholarly writing that supports it. The purpose of this presentation is to show that CWC verification activities can be implemented in the US consistently with the traditional constitutional regard for commercial and individual privacy. First, he very briefly reviews the types of verification inspections that the CWC permits, as well as some of its specific privacy protections. Second, he explains how the Fourth Amendment right to privacy works in the context of CWC verification inspections. Finally, he reviews how verification inspections can be integrated into these constitutional requirements in the SU through a federal implementing statute.

    A radiation disaster was predicted in case of 1 kt nuclear weapon terrorism on the surface. Despite small size, serious radiation exposure became clear in a range more than 10 km that can't be by an aerial explosion. This kind of exposure comes from radioactive fallout of fission products, not from direct nuclear radiation. This spreads to a lee area. More than 1,000,000 population receive a serious dose including fatal dose if the nuclear disaster occurs in Tokyo is expected. If adequate radiation protection applies to the population, 70% of victim may be saved. A method to be effective as this kind of protection is escape from a danger zone by the subway after more than one hour sheltering in a concrete building. (author)

  17. Why are sexually selected weapons almost absent in females?

    Directory of Open Access Journals (Sweden)

    Anders BERGLUND

    2013-08-01

    Full Text Available In sex role reversed species, predominantly females evolve sexually selected traits, such as ornaments and/or weapons. Female ornaments are common and their function well documented in many species, whether sex role reversed or not. However, sexually selected female weapons seem totally absent except for small wing spurs in three jacana species, present in both males and females. This poor female weaponry is in sharp contrast to the situation in species with conventional sex roles: males commonly have evolved sexually selected weapons as well as ornaments. At the same time, females in many taxa have naturally selected weapons, used in competition over resources or in predator defence. Why are sexually selected weapons then so rare, almost absent, in females? Here I briefly review weaponry in females and the function of these weapons, conclude that the near absence of sexually selected weapons begs an explanation, and suggest that costs of sexually selected weapons may exceed costs of ornaments. Females are more constrained when evolving sexually selected traits compared to males, at least compared to those males that do not provide direct benefits, as trait costs reduce a female’s fecundity. I suggest that this constraining trade-off between trait and fecundity restricts females to evolve ornaments but rarely weapons. The same may apply to paternally investing males. Whether sexually selected weapons actually are more costly than sexually selected ornaments remains to be investigated [Current Zoology 59 (4: 564–568, 2013].

    This seminar is another excellent opportunity for those involved in preventing chemical weapons production and use to learn from each other about how the Chemical Weapons Convention (CWC) can become a foundation of arms control in Africa and around the world. The author is grateful to the staff of the Organization for the Prohibition of Chemical Weapons (OPCW) for inviting him to address this distinguished seminar. The views expressed in this paper are those of the authors alone, and do not represent the position of the government of the US nor or of any other institution. In 1993, as the process of CWC ratification was beginning, concerns arose that the complexity of integrating the treaty with national law would cause each nation to implement the Convention without regard to what other nations were doing, thereby causing inconsistencies among States Parties in how the Convention would be carried out. As a result the Manual for National Implementation of the Chemical Weapons Convention was prepared and presented it to each national delegation at the December 1993 meeting of the Preparatory Commission in The Hague. During its preparation, the Manual was reviewed by the Committee of Legal Experts on National Implementation of the Chemical Weapons Convention, a group of distinguished international jurists, law professors, legally-trained diplomats, government officials, and Parliamentarians from every region of the world, including Mica. In February 1998, the second edition of the Manual was published in order to update it in light of developments since the CWC entered into force on 29 April 1997. The second edition 1998 clarified the national implementation options to reflect post-entry-into-force thinking, added extensive references to national implementing measures that had been enacted by various States Parties, and included a prototype national implementing statute developed by the authors to provide a starting point for those whose national implementing

  20. Safeguards for a nuclear weapon convention

    International Nuclear Information System (INIS)

    Fischer, D.

    1999-01-01

    An NDT presupposes a fundamental commitment by all parties to its final objective and hence requires a high and sustained level of confidence amongst all states concerned. The appropriate format for an Nuclear Disarmament Treaty (NDT) would probably be a multilateral treaty open to all states. The treaty must necessarily include the five nuclear weapon states and a procedure would have to be found for securing the ratification of the threshold states without conferring upon them the status of nuclear weapon states. While the IAEA may well be able to carry out the safeguards tasks required by an NDT it would probably be necessary to establish a new international organization to verify the elimination of all nuclear weapons. The experience of UNSCOM and the IAEA in Iraq, and of the IAEA in the DPRK, have shown how difficult the verification of international obligations is in the absence of a commitment to disarm, while the experience of the INF and START treaties, and of the IAEA in South Africa have shown how much simpler it is when the parties concerned are fully committed to the process. Verifying and safeguarding an NDT would be largely an extrapolation of activities already carried out by the nuclear weapon states under the INF and START treaties and by the IAEA in the routine application of safeguards as well as in its less routine work in Iraq, South Africa and the DPRK. Both the verification and safeguarding tasks would be made very much easier if it were possible to bring down to a few hundred the number of nuclear warheads remaining in the hands of any avowed nuclear weapon state, and to conclude a cutoff convention. Experience is needed to show whether the additional safeguards authority accorded to the IAEA by 'programme 93+2' will enable it to effectively safeguard the facilities that would be decommissioned as a result of an NDT and those that would remain in operation to satisfy civilian needs. Subject to this rider and on condition that the IAEA

    The isotopes 236 U, 239 Pu and 240 Pu are present in surface soils as a result of global fallout from nuclear weapons tests carried out in the 1950's and 1960's. These isotopes potentially constitute artificial tracers of recent soil erosion and sediment movement. Only Accelerator Mass Spectrometry has the requisite sensitivity to measure all three isotopes at these environmental levels. Coupled with its relatively high throughput capabilities, this makes it feasible to conduct studies of erosion across the geographical extent of the Australian continent. In the Australian context, however, global fallout is not the only source of these isotopes. As part of its weapons development program the United Kingdom carried out a series of atmospheric and surface nuclear weapons tests at Maralinga, South Australia in 1956 and 1957. The tests have made a significant contribution to the Pu isotopic abundances present in the region around Maralinga and out to distances ∼1000 km, and impact on the assessment techniques used in the soil and sediment tracer studies. Quantification of the relative fallout contribution derived from detonations at Maralinga is complicated owing to significant contamination around the test site from numerous nuclear weapons safety trials that were also carried out around the site. We show that 236 U can provide new information on the component of the fallout that is derived from the local nuclear weapons tests, and highlight the potential of 236 U as a new fallout tracer. - Highlights: • Measured 236 U inventories around the Maralinga Test Nuclear weapons test site. • Comparison of 236 U and 239 Pu soil depth profiles at Maralinga. • Differences in 236 U and 239 Pu inventories indicate most Pu fallout is from the safety trials, rather than the weapons tests.

  3. The real value of nuclear-weapon-free zones

    1998-01-01

    The international community has greeted the establishment of two new nuclear weapon-free zones with praise. Africa and South Asia are the regions which will join, once the respective treaties are ratified and in force, Latin America and the South Pacific to ensure that extensive areas of the earth remain free of nuclear weapons. The usual reaction to these accomplishments is to hail them as important contributions to international peace and security, and as meaningful steps towards a world free of nuclear weapons. The nuclear weapon-free zones have their value but this value relates mainly to the countries within the zone. The interest of nuclear-weapon states are not really affected, or, if they are, the influence is not significant. One should bear in mind that the really important and meaningful nuclear weapon-free zones have yet to be achieved

    The shapes of sexually selected weapons differ widely among species, but the drivers of this diversity remain poorly understood. Existing explanations suggest weapon shapes reflect structural adaptations to different fighting styles, yet explicit tests of this hypothesis are lacking. We constructed finite element models of the horns of different rhinoceros beetle species to test whether functional specializations for increased performance under species-specific fighting styles could have contributed to the diversification of weapon form. We find that horns are both stronger and stiffer in response to species-typical fighting loads and that they perform more poorly under atypical fighting loads, which suggests weapons are structurally adapted to meet the functional demands of fighting. Our research establishes a critical link between weapon form and function, revealing one way male-male competition can drive the diversification of animal weapons.

  5. (236)U and (239,)(240)Pu ratios from soils around an Australian nuclear weapons test site.

    The isotopes (236)U, (239)Pu and (240)Pu are present in surface soils as a result of global fallout from nuclear weapons tests carried out in the 1950's and 1960's. These isotopes potentially constitute artificial tracers of recent soil erosion and sediment movement. Only Accelerator Mass Spectrometry has the requisite sensitivity to measure all three isotopes at these environmental levels. Coupled with its relatively high throughput capabilities, this makes it feasible to conduct studies of erosion across the geographical extent of the Australian continent. In the Australian context, however, global fallout is not the only source of these isotopes. As part of its weapons development program the United Kingdom carried out a series of atmospheric and surface nuclear weapons tests at Maralinga, South Australia in 1956 and 1957. The tests have made a significant contribution to the Pu isotopic abundances present in the region around Maralinga and out to distances ∼1000 km, and impact on the assessment techniques used in the soil and sediment tracer studies. Quantification of the relative fallout contribution derived from detonations at Maralinga is complicated owing to significant contamination around the test site from numerous nuclear weapons safety trials that were also carried out around the site. We show that (236)U can provide new information on the component of the fallout that is derived from the local nuclear weapons tests, and highlight the potential of (236)U as a new fallout tracer.

    1994-01-01

    This report presents preliminary considerations for recovering and converting weapon plutonium from various US weapon forms into feed material for fabrication of reactor fuel elements. An ongoing DOE study addresses the disposition of excess weapon plutonium through its use as fuel for nuclear power reactors and subsequent disposal as spent fuel. The spent fuel would have characteristics similar to those of commercial power spent fuel and could be similarly disposed of in a geologic repository

  9. What Happens to Deterrence as Nuclear Weapons Decrease Toward Zero?

    Science.gov (United States)

    2011-04-01

    Steps reducing reliance on deployed nuclear weapons en route to zero will be discussed. They include broadly enhancing cooperation and transparency agreements beyond the provisions for verifying limits on deployed strategic nuclear warheads and delivery systems in the New START treaty. Two questions that will be addressed are: What conditions would have to be established in order to maintain strategic stability among nations as nuclear weapons recede in importance? What would nuclear deterrence be like in a world without nuclear weapons?

    Besides presenting data in a format useful to plasma modellers, these data collection activities also serve the function of disclosing gaps in the available data base. The IAEA review panel has pointed out that information on processes of electron ejection and reflection is sparse and is generally unsatisfactory for purposes of modelling sheath effects. The US and Japanese Data Centers recently held a joint workshop where it was concluded that data on trapping and reemission was in an unsatisfactory state. In this case the parameters used to record the phenomena are closely related to the model adopted to describe the process. Existing handbooks on materials are generally weak in the areas closely related to metallurgical properties. All three data centers continue to pursue different aspects of the data collection and review process with a close interaction to avoid significant overlap of activities

  11. Nuclear weapons in Europe: Why zero is better

    International Nuclear Information System (INIS)

    Daalder, I.H.

    1993-01-01

    Given the fundamental changes in the political context and NATO's perception of nuclear weapons, what role remains for US nuclear weapons in preserving security in Europe? Are US nuclear deployments on the continent still necessary? Is there a requirement for extended deterrence and, if so, does its credibility depend on the continued basing of US nuclear weapons in Europe? And what is the role of arms control in effecting any desirable restructuring in nuclear force postures? In addressing these questions, it becomes clear that US nuclear weapons can now be removed from Europe - they no longer serve the political and military functions they once did

  13. ON THE OFFENSE: USING CYBER WEAPONS TO INFLUENCE COGNITIVE BEHAVIOR

    Directory of Open Access Journals (Sweden)

    Mary Fendley

    2012-12-01

    Full Text Available There is an increasing recognition that cyber warfare is an important area of development for targeting and weaponeering, with far-reaching effects in national defense and economic security. The ability to conduct effective operations in cyberspace relies on a robust situational awareness of events occurring in both the physical and information domains, with an understanding of how they affect the cognitive domain of friendly, neutral, and adversary population sets. The dynamic nature of the battlefield complicates efforts to understand shifting adversary motivations and intentions. There are very few approaches, to date, that systematically evaluate the effects of the repertoire of cyber weapons on the cognitive, perceptual, and behavioral characteristics of the adversary. In this paper, we describe a software environment called Cognitive Cyber Weapon Selection Tool (CCWST that simulates a scenario involving cyber weaponry.This tool provides the capabilities to test weapons which may induce behavioral state changes in the adversaries. CCWST provides the required situational awareness to the Cyber Information Operations (IO planner to conduct intelligent weapon selection during weapon activation in order to induce the desired behavioral change in the perception of the adversary. Weapons designed to induce the cognitive state changes of deception, distraction, distrust and confusion were then tested empirically to evaluate the capabilities and expected cognitive state changes induced by these weapons. The results demonstrated that CCWST is a powerful environment within which to test and evaluate the impact of cyber weapons on influencing cognitive behavioral states during information processing.

  14. Strategies for denaturing the weapons-grade plutonium stockpile

    International Nuclear Information System (INIS)

    Buckner, M.R.; Parks, P.B.

    1992-10-01

    In the next few years, approximately 50 metric tons of weapons-grade plutonium and 150 metric tons of highly-enriched uranium (HEU) may be removed from nuclear weapons in the US and declared excess. These materials represent a significant energy resource that could substantially contribute to our national energy requirements. HEU can be used as fuel in naval reactors, or diluted with depleted uranium for use as fuel in commercial reactors. This paper proposes to use the weapons-grade plutonium as fuel in light water reactors. The first such reactor would demonstrate the dual objectives of producing electrical power and denaturing the plutonium to prevent use in nuclear weapons

    Full Text Available In November 2016 in the Moscow Kremlin State Historical and Cultural Museum and Heritage Site in the framework of events dedicated to the 210th anniversary of the Armoury Chamber museum, an international conference “Historical weapons in museums and private collections”. This scientific forum continued the tradition of conferences held in the Moscow Kremlin Museums in 1999-2007. The participants of this forum discussed a number of priority topics for the studies of the weapon collection history in the Kremlin. These topics were relevant to the national and world studies of weaponology as a whole. In addition to general issues of the history of arms and armour, a number of reports were devoted to the functioning of the historical centers of arms production, weapons collections in Russia and abroad, particular items, as well as the activities of gunsmiths, designers of weapons. The conference was attended by representatives of more than 20 Russian and foreign museums, 14 academic and university research centers and institutions, private collectors and lovers of ancient weapons. During the three days of the conference 36 reports were presented and discussed. Organizers of the conference highlighted a number of reports including new attributions of the items from the Kremlin collections. The conference program is available on the official website of the Moscow Kremlin State Museums. The conference results were published as a collection of proceedings. The weaponology forum in the Kremlin will be held annually. The Moscow Kremlin Museums invite researchers of historical weapons, museum employees and collectors to the active cooperation.

    2007-04-01

    The nuclear build-up of the United States and the Soviet Union during the Cold War is often portrayed as an arms race. Some part was indeed a bilateral competition, but much was the result of automatic application of technical advances as they became available, without careful consideration of strategic implications. Thus, the history of nuclear weapon design is partly designers responding to stated military needs and partly the world responding to constant innovations in nuclear capability. Today, plans for a new nuclear warhead are motivated primarily by the desire to maintain a nuclear design and production capability for the foreseeable future.

  1. A strategy for weapons-grade plutonium disposition

    Energy Technology Data Exchange (ETDEWEB)

    Sylvester, K.W.B. [Iowa State Univ., Ames, IA (United States)

    1994-09-01

    A political as well as technical analysis was performed to determine the feasibility of glassification (vitrification) for weapons grade plutonium (WGPu) disposition. The political analysis provided the criteria necessary to compare alternative storage forms. The technical areas of weapon useability and environmental safety were then computationally and experimentally explored and a vitrification implementation strategy postulated. The Monte Carlo Neutron Photon (MCNP) computer code was used to model the effect of blending WGPu with reactor grade Pu (RGPu). A mixture of 30% RGPu and 70% WGPu more than doubled the surface flux from a bare sphere of the mixture which assumedly correlates to a significantly increased predetonation probability. Rare earth diluents were also examined (using MCNP) for their ability to increase the compressed critical mass of the WGPu mixture. The rare earths (notably Eu) were effective in this regard. As Pu-239 has a 24,100 year half life, reactivity control in the long term is an environmental safety issue. Rare earths were investigated as criticality controllers due to their neutron absorption capabilities and insolubility in aqueous environments. Thorium (a Pu surrogate) and the rare earths Eu, Gd, and Sm were added to two standard frits (ARM-1 and SRL-165) and formed into glass. Aqueous leach tests were performed (using MCC-1P guidelines) to measure rare earth leaching and determine the added elements` effects on glass durability. Europium was much more leach resistant than boron in the glasses tested. The elements had no negative effect on the environmental durability of the glasses tested at 90 C and minimal effect at room temperature. No fission product releases were detected in the ARM-1 compositions (which contained numerous simulated fission products).

  3. Is the nuclear weapon taboo? The nuclear weapon is useless and expensive. Let us not leave the nuclear weapon as an inheritance

    Gauchet, Nathalie; Norlain, Bernard; Beach, Hugh; Beckett, Margaret; Quiles, Paul; Rocard, Michel; Ramsbotham, David

    2012-03-01

    Starting with the definition of the word taboo as stated in a dictionary (a topic it would be unbecoming to evoke, under social and moral proprieties), the author of the first article discusses the status of the nuclear weapon, outlining that it is expensive, useless and monstrous. She notices that conventions on chemical weapons seem to be more efficient than the NPT, that, even if the reasons for abolition are known as well as ways to reach it, it seems difficult to actually address this issue. She evokes different voices coming from different countries or international bodies calling for this abolition. She also states that the nuclear weapon is not a deterrent weapon but a weapon of domination, and calls for the mobilisation of the civil society throughout the world. A second article states that the nuclear weapon is useless and expensive, and that we have to get rid of this hazard for the sake of the planet. Former ministers, Prime ministers, and generals consider that we can and must give up nuclear weapons, notably because the strategic context has completely changed since the fall of the Berlin wall, and support the action of Global Zero

  4. The Regulation of the Possession of Weapons at Gatherings

    Directory of Open Access Journals (Sweden)

    Pieter du Toit

    2013-12-01

    Full Text Available The Dangerous Weapons Act 15 of 2013 provides for certain prohibitions and restrictions in respect of the possession of a dangerous weapon and it repeals the Dangerous Weapons Act 71 of 1968 as well as the different Dangerous Weapons Acts in operation in the erstwhile TBVC States. The Act also amends the Regulation of Gatherings Act 205 of 1993 to prohibit the possession of any dangerous weapon at a gathering or demonstration. The Dangerous Weapons Act provides for a uniform system of law governing the use of dangerous weapons for the whole of South Africa and it furthermore no longer places the onus on the individual charged with the offence of the possession of a dangerous weapon to show that he or she did not have any intention of using the firearm for an unlawful purpose. The Act also defines the meaning of a dangerous weapon. According to our court’s interpretation of the Dangerous Weapons Act 71 of 1968 a dangerous weapon was regarded as an object used or intended to be used as a weapon even if it had not been designed for use as a weapon. The Act, however, requires the object to be capable of causing death or inflicting serious bodily harm if it were used for an unlawful purpose. The possession of a dangerous weapon, in circumstances which may raise a reasonable suspicion that the person intends to use it for an unlawful purpose, attracts criminal liability. The Act also provides a useful set of guidelines to assist courts to determine if a person charged with the offence of the possession of a dangerous weapon had indeed intended to use the weapon for an unlawful purpose. It seems, however, that the Act prohibits the possession of a dangerous weapon at gatherings, even if the person carrying the weapon does not intend to use it for an unlawful purpose. The state will, however, have to prove that the accused had the necessary control over the object and the intention to exercise such control, as well as that the object is capable of

    The enhancement and quenching of Eu3+ ion emission were investigated in Zn2SnO4:Eu3+@Au (ZTO:Eu3+@Au) nanocomposites. Under 361 nm excitation we revealed the extinction of the intrinsic defect emission and the enhancement of Eu3+ ion emission when Au content in samples is increased, but under excitation wavelength of 394 nm we observed only the suppression of Eu3+ ion emission. The cause of the observed PL behavior is related to the interaction between surface plasmon induced by gold nanoparticles and luminescence centers in the samples.

    Bitzek, Erik; Gumbsch, Peter

    2004-01-01

    Atomistic simulations of an accelerating edge dislocation were carried out to study the effects of drag and inertia. Using an embedded atom potential for nickel, the Peierls stress, the effective mass and the drag coefficient of an edge dislocation were determined for different temperatures and stresses in a simple slab geometry. The effect of {1 1 1} surfaces on an intersecting edge dislocation were studied by appropriately cutting the slab. A dislocation intersecting a surface step was used as a model system to demonstrate the importance of inertial effects for dynamically overcoming short range obstacles. Significant effects were found even at room temperature. A simple model based on the dislocation-obstacle interaction energies was used to describe the findings

    2000-01-01

    The Office of Fissile Materials Disposition is responsible for disposing of inventories of surplus US weapons-usable plutonium and highly enriched uranium as well as providing, technical support for, and ultimate implementation of, efforts to obtain reciprocal disposition of surplus Russian plutonium. On January 4, 2000, the Department of Energy issued a Record of Decision to dispose of up to 50 metric tons of surplus weapons-grade plutonium using two methods. Up to 17 metric tons of surplus plutonium will be immobilized in a ceramic form, placed in cans and embedded in large canisters containing high-level vitrified waste for ultimate disposal in a geologic repository. Approximately 33 metric tons of surplus plutonium will be used to fabricate MOX fuel (mixed oxide fuel, having less than 5% plutonium-239 as the primary fissile material in a uranium-235 carrier matrix). The MOX fuel will be used to produce electricity in existing domestic commercial nuclear reactors. This paper reports the major waste-package-related, long-term disposal impacts of the two waste forms that would be used to accomplish this mission. Particular emphasis is placed on the possibility of criticality. These results are taken from a summary report published earlier this year

    After a brief history of the Iranian nuclear crisis since 2003, the author discusses the four aspects of this crisis which make it a textbook case: a country which wants to control the whole nuclear process and therefore may reach the capacity to produce military-grade uranium (this raises the question of the relationship between nuclear energy and disarmament), the validity and efficiency of international controls is at stake, divergence may appear on the ways to have international treaties respected (different approaches between Europe and the USA), a country which is looking for nuclear weapon for matters of regional security and power (this raises the issue of a new approach to security). Then, the author describes the new nuclear threats: proliferating states, terrorist groups, and states with nuclear weapons (attitude of the USA, China, Russia, France and the United Kingdom, perspective of a nuclear disarmament of Europe). He gives an overview of the current status of disarmament and of treaties (START, NPT), and discusses the opportunities to save the non proliferation treaty from collapsing in 2005

  10. Nuclear weapons complex: What went wrong?

    International Nuclear Information System (INIS)

    Martin, J.E.

    1991-01-01

    The nuclear weapons complex has generated significant volumes of radioactive wastes dating back to the 1940s. Such wastes included transuranic radioisotopes-for example, plutonium-generated as byproducts of the operations. Most of these wastes at the major disposal site were not classified in the same way nuclear wastes are classified today; the definitions of high- and low-level wastes have changed over time, and, in the case of the latter, different classes have been established that determine methods for disposal and handling. Waste disposal was not a high priority during World War II. After the war, however; resources were not committed to either waste-disposal research or the development of a national waste management policy. AEC's failure to develop a national policy on radioactive waste disposal is easier to understand than to excuse. The disposal problem parallels the chemical waste disposal situation, where there were no federal and few state laws regulating chemical waste disposal until 1976, following publicity about Love Canal. This same story has been repeated for radioactive and mixed wastes and facility safety at the nation's nuclear weapon sites

    2000-01-01

    This study on nuclear futures is a product of work undertaken by the Mountbatten Centre for International Studies (MCIS) of the University of Southampton. The study has pursued three goals: to attempt to understand the dynamics of the nuclear present; to elucidate a range of possible nuclear futures that may emerge; and to assess different strategies that could be pursued in response to these futures, including proposals for promoting nuclear disarmament. The aim was to draw on research, meetings and outreach to achieve these goals, and to use the knowledge gained to help inform the international policy-making community. The work underlying this study was divided into two stages. During the first stage, the apparent threat perceptions of the five acknowledged NWS (China, France, Russia, the UK and the United States) and the three de facto NWS (India, Israel and Pakistan) were explored . The purpose of this research was to identify the main factors (or shapers) that seem to have influenced nuclear weapons policy in all these states, and to assess their relative importance. The second stage of the work drew on the conclusions reached on the eight countries. The shapers were divided into categories on the basis of their apparent impact on nuclear weapons policy. This study summarizes the main conclusions reached in the course of this work

  12. Nuclear power and nuclear weapons proliferation

    International Nuclear Information System (INIS)

    Anon.

    1978-01-01

    An appropriate non-proliferation treaty should not discriminate among the non-weapon states, but should seek a cooperative approach with all countries seeking nuclear power and willing to accept international safeguards. Near-term proliferation problems, represented by nations already on the threshold of weapon capability, should not be confused with the long-term problem of world-wide nuclear development. The first can be handled with incentives and disincentives imposed on specific countries, while the latter involves the distribution of plutonium on the basis of alternative fuel cycles. To retain world leadership, U.S. efforts along these lines should be to encourage a dialogue between suppliers and recipients and to coordinate the economic and security issues of its own non-proliferation and foreign policies. One option is a U.S. commitment to a multinational fuel storage and reprocessing facility. Technical evaluation and demonstration of alternative fuel cycles to reach an international consensus would be a parallel activity

    The U.S. government has been assisting the Russian Federation (RF) Ministry of Defense (MOD) for many years with nuclear weapons transportation security (NWTS) through the provision of specialized guard escort railcars and cargo railcars with integrated physical security and communication systems, armored transport vehicles, and armored escort vehicles. As a natural continuation of the NWTS program, a partnership has been formed to construct a training center that will provide counterterrorism training to personnel in all branches of the RF MOD. The Abramovo Counterterrorism Training Center (ACTC) is a multinational, multiagency project with funding from Canada, RF and the U.S. Departments of Defense and Energy. ACTC will be a facility where MOD personnel can conduct basic through advanced training in various security measures to protect Category IA material against the threat of terrorist attack. The training will enhance defense-in-depth principles by integrating MOD guard force personnel into the overall physical protection systems and improving their overall response time and neutralization capabilities. The ACTC project includes infrastructure improvements, renovation of existing buildings, construction of new buildings, construction of new training facilities, and provision of training and other equipment. Classroom training will be conducted in a renovated training building. Basic and intermediate training will be conducted on three different security training areas where various obstacles and static training devices will be constructed. The central element of ACTC, where advanced training will be held, is the 'autodrome,' a 3 km road along which various terrorist events can be staged to challenge MOD personnel in realistic and dynamic nuclear weapons transportation scenarios. This paper will address the ACTC project elements and the vision for training development and integrating this training into actual nuclear weapons transportation operations.

    In war, the weapons and technologies employed have direct effects on how battles are waged. When new weapons are introduced, they can dramatically alter the outcomes of warfare-and consequently change the course of history itself. This reference work provides a fascinating overview of the major weapon systems and military technologies that have had a major impact on world history. Addressing weapons as crude as the club used by primitive man to the high-tech weapons of today such as unmanned drones, Instruments of War: Weapons and Technologies That Have Changed History offers nearly 270 profusely illustrated entries that examine the key roles played by specific weapons and identify their success and failures. The book begins with an introductory essay that frames the subject matter of the work and discusses the history of weapons as a whole. The text is concise and accessible to general readers without extensive backgrounds in military history yet provides the detailed information necessary to convey the comp...

  9. Emerging nuclear energy systems and nuclear weapon proliferation

    International Nuclear Information System (INIS)

    Gsponer, A.; Sahin, S.; Jasani, B.

    1983-01-01

    Generally when considering problems of proliferation of nuclear weapons, discussions are focused on horizontal proliferation. However, the emerging nuclear energy systems currently have an impact mainly on vertical proliferation. The paper indicates that technologies connected with emerging nuclear energy systems, such as fusion reactors and accelerators, enhance the knowledge of thermonuclear weapon physics and will enable production of military useful nuclear materials (including some rare elements). At present such technologies are enhancing the arsenal of the nuclear weapon states. But one should not forget the future implications for horizontal proliferation of nuclear weapons as some of the techniques will in the near future be within the technological and economic capabilities of non-nuclear weapon states. Some of these systems are not under any international control. (orig.) [de

  10. Proposals for chemical weapons during the American Civil War.

    Hasegawa, Guy R

    2008-05-01

    Proposals for chemical weapons that arose during the American Civil War are described. Most incendiary and all biological agents are excluded. The described proposals appeared primarily in periodicals or letters to government officials on both sides. The weapons were usually meant to temporarily disable enemy combatants, but some might have been lethal, and Civil War caregivers were ill-prepared to deal with the weapons' effects. Evidently, none of the proposed weapons were used. In only one instance was use against civilians mentioned. Among the agents most commonly proposed were cayenne pepper or other plant-based irritants such as black pepper, snuff, mustard, and veratria. Other suggested agents included chloroform, chlorine, hydrogen cyanide, arsenic compounds, sulfur, and acids. Proponents usually suggested that the chemicals be included in explosive artillery projectiles. Less commonly proposed vehicles of delivery included fire engines, kites, and manned balloons. Some of the proposed weapons have modern counterparts.

    This preliminary note about is important to consider when discussing hopes of achieving a nuclear-weapon-free world. Without a serious effort to establish intelligent, powerful bodies to control and judge the behavior of the nations on Earth, whatever they future weapons may be, the objective to reach a nuclear-weapon-free world may even succeed, but it is not enough to stop wars and death. Even more than that: if taken alone, as the 'Great Way', it could prove negative, for it could slow down the general effort to achieve peace on out planet. A nuclear-weapon-free world is of course a very good idea but two points must be discussed: how to achieve the nuclear-weapon-free world; and what will happen afterwards. Some considerations on the second point are made

    The focus of the project was to design and synthesize light element compounds and nanomaterials that will reversibly store molecular hydrogen for hydrogen storage materials. The primary targets investigated during the last year were amine and hydrogen terminated silicon (Si) nanoparticles, Si alloyed with lighter elements (carbon (C) and boron (B)) and boron nanoparticles. The large surface area of nanoparticles should facilitate a favorable weight to volume ratio, while the low molecular weight elements such as B, nitrogen (N), and Si exist in a variety of inexpensive and readily available precursors. Furthermore, small NPs of Si are nontoxic and non-corrosive. Insights gained from these studies will be applied toward the design and synthesis of hydrogen storage materials that meet the DOE 2010 hydrogen storage targets: cost, hydrogen capacity and reversibility. Two primary routes were explored for the production of nanoparticles smaller than 10 nm in diameter. The first was the reduction of the elemental halides to achieve nanomaterials with chloride surface termination that could subsequently be replaced with amine or hydrogen. The second was the reaction of alkali metal Si or Si alloys with ammonium halides to produce hydrogen capped nanomaterials. These materials were characterized via X-ray powder diffraction, TEM, FTIR, TG/DSC, and NMR spectroscopy.

  13. Psychological markers underlying murder weapon profile: a quantitative study.

    The horrific nature of murder using different types of weapons has been an important focal point of many criminological studies. Weapons that are used in murders seem to play dominant roles in murder investigations as they may provide information leading to arrest. The established factors for weapon usage include environmental context, demography and availability of weapons. However, there is insufficient research attention on the psychological functioning of murderers for particular weapon usage. In light of this, the current study seeks to narrow this gap of information by identifying the influences of psychological traits on weapon usage among a sample of male murderers. The present cross-sectional study was conducted among 71 male murderers incarcerated in 11 prisons within Peninsular Malaysia. The selection of the sample was based on predetermined selection criteria using a purposive sampling method. A guided self-administered questionnaire comprising sociodemography variables and four Malay validated psychometric instruments: Zuckerman-Kuhlman Personality Questionnaire-40-Cross-Culture, Self-control Scale, "How I Think" Questionnaire and Aggression Questionnaire; was used. Independent sample t-test was performed to establish the mean score differences of psychological traits between the murderers who used single and multiple weapons while Kruskal-Wallis tests were carried out to ascertain the differences between the specific types of weapons used among the murderers. Following this, one-way ANOVA was carried out to ascertain the psychological trait differences among the murderers according to the different sources of weapon. Results indicated specific psychological traits influenced the number(s), source(s) and type(s) of weapon used in committing murder. The findings have implications for the psychological profiling of unknown murderers within the Malaysian context.

  14. Nuclear weapons issues in South Asia

    Joeck, N.

    1993-07-02

    This report discusses how the US can play a productive mediating role in South Asia by engaging India and Pakistan in an international forum to manage nuclear weapons, as Edward Teller advocated. India and Pakistan have developed their nuclear capabilities because they fear their neighbors, not because they want to threaten fear their neighbors, not because they want to threaten the US. The appropriate response for the US, therefore, is diplomatic engagement and negotiations. In addition to the international approach, encouragement and facilitation of regional and bilateral interactions will also be important. Formal arms control agreements have been reached, but less formal confidence-building measures, and unilateral security pledges may well be combined to form a more secure strategic environment in South Asia than a nuclear armed confrontation across the porous South Asian border.

    Passive dripping, the slow dripping of blood under gravity, is responsible for some bloodstains found at crime scenes, particularly drip trails left by a person moving through the scene. Previous work by other authors has established relationships, under ideal conditions, between the size of the stain, the number of spines and satellite stains, the roughness of the surface, the size of the blood droplet and the height from which it falls. To apply these relationships to infer the height of fall requires independent knowledge of the size of the droplet. This work aims to measure the size of droplets falling from objects representative of hand-held weapons. Pig blood was used, with density, surface tension and viscosity controlled to fall within the normal range for human blood. Distilled water was also tested as a reference. Drips were formed from stainless steel objects with different roughnesses including cylinders of diameter between 10 and 100 mm, and flat plates. Small radius objects including a knife and a wrench were also tested. High speed images of the falling drops were captured. The primary blood drop size ranged from 4.15±0.11 mm up to 6.15±0.15 mm (depending on the object), with the smaller values from sharper objects. The primary drop size correlated only weakly with surface roughness, over the roughness range studied. The number of accompanying droplets increased with the object size, but no significant correlation with surface texture was observed. Dripping of blood produced slightly smaller drops, with more accompanying droplets, than dripping water. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

The effect of process variables such as extraction temperature (30–50 °C, power of ultrasound (20–40 W, extraction time (10–30 min and solid–liquid ratio (1:10–1:20 g/ml is studied. Multiple regression analysis was done on the experimental data to develop second-order polynomial models with high coefficient of determination value (R2 > 0.99. The optimal conditions based on both individual and combinations of all process variables (extraction temperature of 50 °C, ultrasound power of 20 W, extraction time of 20 min and solid–liquid ratio of 1:18.6 g/ml were determined by Derringer’s desired function methodology. Under these conditions, total anthocyanin (10.26 ± 0.39 (mg/100 g, phenolics (552.64 ± 1.57 (mg GAE/100 g and flavonoid (104 ± 1.13 (mg RE/100 g content values were determined and it is closely related with the predicted values (10.17 mg/100 g of total anthocyanin, 546.98 mg GAE/100 g of total phenolics and 100.93 mg RE/100 g of total flavonoid content and indicted the suitability of the developed models.

  17. From weapons to waste: The future of the nuclear weapons complex

    International Nuclear Information System (INIS)

    Wasserman Goodman, Sherri

    1992-01-01

    This paper examines how decision-making power has shifted within the nuclear weapons complex, from the federal government operating agency, in which power was originally vested by the Atomic Energy Act, to the states and to regulatory authorities. Additionally, when the original operating agency, the Atomic Energy Commission (AEC), was abolished in the 1970s, substantial decision-making power shifted from Washington to the field sites. This paper identifies the needs for future materials and weapons production, and recommends that restart of old plants be abandoned as no longer militarily necessary. Instead, the U. S. should take advantage of what may be a unique opportunity to 'leapfrog' to new, smaller, technologically-advanced plants that will meet the needs of the nuclear arsenal in the post-Cold War world. This paper then looks at the current state of DOE's environmental restoration/waste management program, and the technological, legal and political problems it faces in trying to accomplish its mission of cleaning up all nuclear weapons sites. This paper argues that the U. S. government no longer has the exclusive authority to make and carry out critical decisions affecting a cleanup program that will cost the U. S. over $200 billion over the next 20-40 years. Moreover, there are competing theories about the principles that should guide the cleanup program. Finally, the author examines alternative futures for the DOE'S environmental restoration/waste management program. (author)

    2012-06-01

    The aim of this work was to improve the ability of electro-Fenton technique for the remediation of wastewater contaminated with synthetic dyes using a model azo dye such as Azure B. Batch experiments were conducted to study the effects of main parameters, such as dye concentration, electrode surface area, treatment time, and voltage. In this study, central composite face-centered experimental design matrix and response surface methodology were applied to design the experiments and evaluate the interactive effects of the four studied parameters. A total of 30 experimental runs were set, and the kinetic data were analyzed using first- and second-order models. The experimental data fitted to the empirical second-order model of a suitable degree for the maximum decolorization of Azure B by electro-Fenton treatment. ANOVA analysis showed high coefficient of determination value (R(2) = 0.9835) and reasonable second-order regression prediction. Pareto analysis suggests that the variables, time, and voltage produce the largest effect on the decolorization rate. Optimum conditions suggested by the second-order polynomial regression model for attaining maximum decolorization were dye concentration 4.83 mg/L, electrode surface area 15 cm(2), voltage 14.19 V, and treatment time of 34.58 min.

  19. Males that drop a sexually selected weapon grow larger testes.

    Costly sexually selected weapons are predicted to trade off with postcopulatory traits, such as testes. Although weapons can be important for achieving access to females, individuals of some species can permanently drop (i.e. autotomize) their weapons, without regeneration, to escape danger. We capitalized on this natural behavior to experimentally address whether the loss of a sexually selected weapon leads to increased testes investment in the leaf-footed cactus bug, Narnia femorata Stål (Hemiptera: Coreidae). In a second experiment, we measured offspring production for males that lost a weapon during development. As predicted, males that dropped a hind limb during development grew significantly larger testes than the control treatments. Hind-limb autotomy did not result in the enlargement of other nearby traits. Our results are the first to experimentally demonstrate that males compensate for natural weapon loss by investing more in testes. In a second experiment we found that females paired with males that lost a hind limb had 40% lower egg hatching success than females paired with intact males, perhaps because of lower mating receptivity to males with a lost limb. Importantly, in those cases where viable offspring were produced, males missing a hind limb produced 42% more offspring than males with intact limbs. These results suggest that the loss of a hind-limb weapon can, in some cases, lead to greater fertilization success. © 2017 The Author(s). Evolution © 2017 The Society for the Study of Evolution.

    The effect of different irradiations (gamma-, UV-radiation, alpha particles, protons, helium ions) on surface properties of oxide materials (SiO{sub 2}, BeO, Al{sub 2}O{sub 3}) is studied. It is established that in such a case surface defects with donor-acceptor properties are formed. The attempt is made to develop a mathematical model of accumulation and destruction of radiation defects and to use it for assessment of oxide-adsorbents efficiency. Depending on ratio of quantity of surface defects to volume ones, which characterizes adsorptive activity of the materials, the oxides studied can be arranged in the following series: SiO{sub 2} > BeO > Al{sub 2}O{sub 3} [Russian] Исследовано влияние различных видов облучения (гамма-, УФ-излучения, альфа-частицы, протоны и ионы гелия) на поверхностные свойства оксидных материалов (SiO{sub 2}, BeO, Al{sub 2}O{sub 3}). Установлено, что при этом образуются поверхностные дефекты, имеющие донорно-акцепторные свойства. Сделана попытка создать математическую модель накопления и гибели радиационных дефектов и использовать эту модель для оценки эффективности адсорбентов-оксидов. В зависимости от отношения количества поверхностных дефектов к объемным, характеризующего поглощающую активность материалов, изученные оксиды можно расположить в следующий ряд: SiO{sub 2} > BeO > Al{sub 2}O{sub 3}.

    Speaking on the problems of preventing proliferations of nuclear weapons and nuclear disarmament the author suggests the following measures to reach these goals: signing a treaty that binds all the nuclear weapon states to the no-first-use principle as a basic policy; the United Nations should put the elimination of nuclear weapons on its agenda; having the treaty safeguarded two-pronged verification regime, one would be technological verification, the second one - so called societal verification which means that not just a group of experts but everybody would be asked to take part in ensuring that the treaty would not be violated

    In this article, the author shows that a nuclear weapon-free world would probably be more dangerous than today's world because benefits of the existence of nuclear weapons are probably more important that the risks related to their existence. He outlines that nuclear deterrence has been very efficient for these last 65 years. He states that the disappearance of nuclear weapons could be envisaged only after a large transformation of safety conditions, but that such transformations are actually not at all under way. It would indeed require peaceful and democratic world governance

    The converter-type negative ion source currently employed at the Los Alamos Neutron Science Center (LANSCE) is based on cesium enhanced surface production of H(-) ion beams in a filament-driven discharge. In this kind of an ion source the extracted H(-) beam current is limited by the achievable plasma density which depends primarily on the electron emission current from the filaments. The emission current can be increased by increasing the filament temperature but, unfortunately, this leads not only to shorter filament lifetime but also to an increase in metal evaporation from the filament, which deposits on the H(-) converter surface and degrades its performance. Therefore, we have started an ion source development project focused on replacing these thermionic cathodes (filaments) of the converter source by a helicon plasma generator capable of producing high-density hydrogen plasmas with low electron energy. In our studies which have so far shown that the plasma density of the surface conversion source can be increased significantly by exciting a helicon wave in the plasma, and we expect to improve the performance of the surface converter H(-) ion source in terms of beam brightness and time between services. The design of this new source and preliminary results are presented, along with a discussion of physical processes relevant for H(-) ion beam production with this novel design. Ultimately, we perceive this approach as an interim step towards our long-term goal, combining a helicon plasma generator with an SNS-type main discharge chamber, which will allow us to individually optimize the plasma properties of the plasma cathode (helicon) and H(-) production (main discharge) in order to further improve the brightness of extracted H(-) ion beams.

  9. Excess Weapons Plutonium Immobilization in Russia

    International Nuclear Information System (INIS)

    Jardine, L.; Borisov, G.B.

    2000-01-01

    The joint goal of the Russian work is to establish a full-scale plutonium immobilization facility at a Russian industrial site by 2005. To achieve this requires that the necessary engineering and technical basis be developed in these Russian projects and the needed Russian approvals be obtained to conduct industrial-scale immobilization of plutonium-containing materials at a Russian industrial site by the 2005 date. This meeting and future work will provide the basis for joint decisions. Supporting R and D projects are being carried out at Russian Institutes that directly support the technical needs of Russian industrial sites to immobilize plutonium-containing materials. Special R and D on plutonium materials is also being carried out to support excess weapons disposition in Russia and the US, including nonproliferation studies of plutonium recovery from immobilization forms and accelerated radiation damage studies of the US-specified plutonium ceramic for immobilizing plutonium. This intriguing and extraordinary cooperation on certain aspects of the weapons plutonium problem is now progressing well and much work with plutonium has been completed in the past two years. Because much excellent and unique scientific and engineering technical work has now been completed in Russia in many aspects of plutonium immobilization, this meeting in St. Petersburg was both timely and necessary to summarize, review, and discuss these efforts among those who performed the actual work. The results of this meeting will help the US and Russia jointly define the future direction of the Russian plutonium immobilization program, and make it an even stronger and more integrated Russian program. The two objectives for the meeting were to: (1) Bring together the Russian organizations, experts, and managers performing the work into one place for four days to review and discuss their work with each other; and (2) Publish a meeting summary and a proceedings to compile reports of all the

  10. (+/-)-catechin: chemical weapon, antioxidant, or stress regulator?

    (+/-)-Catechin is a flavan-3-ol that occurs in the organs of many plant species, especially fruits. Health-beneficial effects have been studied extensively, and notable toxic effects have not been found. In contrast, (+/-)-catechin has been implicated as a 'chemical weapon' that is exuded by the roots of Centaurea stoebe, an invasive knapweed of northern America. Recently, this hypothesis has been rejected based on (+/-)-catechin's low phytotoxicity, instability at pH levels higher than 5, and poor recovery from soil. In the current study, (+/-)-catechin did not inhibit the development of white and black mustard to an extent that was comparable to the highly phytotoxic juglone, a naphthoquinone that is allegedly responsible for the allelopathy of the walnut tree. At high stress levels, caused by sub-lethal methanol concentrations in the medium, and a 12 h photoperiod, (+/-)-catechin even attenuated growth retardation. A similar effect was observed when (+/-)-catechin was assayed for brine shrimp mortality. Higher concentrations reduced the mortality caused by toxic concentrations of methanol. Further, when (+/-)-catechin was tested in variants of the deoxyribose degradation assay, it was an efficient scavenger of reactive oxygen species (ROS) when they were present in higher concentrations. This antioxidant effect was enhanced when iron was chelated directly by (+/-)-catechin. Conversely, if iron was chelated to EDTA, pro-oxidative effects were demonstrated at higher concentrations; in this case (+/-)-catechin reduced molecular oxygen and iron to reagents required by the Fenton reaction to produce hydroxyl radicals. A comparison of cyclic voltammograms of (+/-)-catechin with the phytotoxic naphthoquinone juglone indicated similar redox-cycling properties for both compounds although juglone required lower electrochemical potentials to enter redox reactions. In buffer solutions, (+/-)-catechin remained stable at pH 3.6 (vacuole) and decomposed at pH 7.4 (cytoplasm

  16. Arms Control: US and International efforts to ban biological weapons

    Energy Technology Data Exchange (ETDEWEB)

    1992-12-01

    The Bacteriological (Biological) and Toxin Weapons Convention, the treaty that bans the development, production, and stockpiling and acquisition of biological weapons was opened for signature in 1972 and came into force in 1975 after being ratified by 22 governments, including the depository nations of the USA, the United Kingdom, and the former Soviet Union. In support of the Convention, the USA later established export controls on items used to make biological weapons. Further, in accordance with the 1990 President`s Enhanced Proliferation Control Initiative, actions were taken to redefine and expand US export controls, as well as to encourage multilateral controls through the Australia Group. Thus far, the Convention has not been effective in stopping the development of biological weapons. The principal findings as to the reasons of the failures of the Convention are found to be: the Convention lacks universality, compliance measures are effective, advantage of verification may outweigh disadvantages. Recommendations for mitigating these failures are outlined in this report.

    We had a weapons science breakout session last week. Although it would have been better to hold it closer in time to this workshop, I think that it was very valuable. it may have been less of a 'short-sleeve' workshop environment than we would have liked, but as the first time two communities-the weapons community and the neutron scattering community- got together, it was a wonderful opportunity to transfer information during the 24 presentations that were made.

    The author studies the actual situation of nuclear deterrence policies, the possibilities of use chemical weapons as massive destructions weapons for non nuclear governments. The situation of non proliferation of nuclear weapons took a new interest with the disintegration of the communism block, but it seems that only few nuclear matter disappeared towards proliferating countries. The denuclearization of Bielorussia, Ukraine and Kazakhstan makes progress with the START I treaty; China has signed the Non proliferation treaty in 1992, it conducts an export policy in matter of equipment and know-how, towards Iran, Pakistan, North Korea, Saudi Arabia and Syria. In a future of ten years, countries such, Iran, North Korea could catch up with Israel, India and Pakistan among non declared nuclear countries. For chemical weapon, Libya, Iran and Syria could catch up with Iraq. (N.C.)

    This report reviews aspects of the military applications of the inertial confinement fusion (ICF) program at Sandia Laboratories. These applications exist in the areas of: (1) weapon physics research, and (2) weapon effects simulation. In the area of weapon physics research, ICF source technology can be used to study: (1) equations-of-state at high energy densities, (2) implosion dynamics, and (3) laboratory simulation of exoatmospheric burst phenomena. In the area of weapon effects simulation, ICF technology and facilities have direct near, intermediate, and far term applications. In the near term, short pulse x-ray simulation capabilities exist for electronic component effects testing. In the intermediate term, capabilities can be developed for high energy neutron exposures and bremsstrahlung x-ray exposures of components. In the far term, system level exposures of full reentry vehicles will be possible if sufficiently high pellet gains are achieved

    This book discusses the acquisition of nuclear weapons by India and Pakistan and its effect on security of the South Asian region. The author uses quantitative analysis to establish the relationship between nuclearization and conventional stability in the region between 1971 and 2002. He shows a positive correlation between nuclear proliferation and conventional instability during these three decades. Thus, this study affirms that nuclear weapons have failed to prevent conflict in South Asia. In fact, they have escalated tensions

  10. The evolution of tail weaponization in amniotes.

    Arbour, Victoria M; Zanno, Lindsay E

    2018-01-31

    Weaponry, for the purpose of intraspecific combat or predator defence, is one of the most widespread animal adaptations, yet the selective pressures and constraints governing its phenotypic diversity and skeletal regionalization are not well understood. Here, we investigate the evolution of tail weaponry in amniotes, a rare form of weaponry that nonetheless evolved independently among a broad spectrum of life including mammals, turtles and dinosaurs. Using phylogenetic comparative methods, we test for links between morphology, ecology and behaviour in extant amniotes known to use the tail as a weapon, and in extinct taxa bearing osseous tail armaments. We find robust ecological and morphological correlates of both tail lashing behaviour and bony tail weaponry, including large body size, body armour and herbivory, suggesting these life-history parameters factor into the evolution of antipredator behaviours and tail armaments. We suggest that the evolution of tail weaponry is rare because large, armoured herbivores are uncommon in extant terrestrial faunas, as they have been throughout evolutionary history. © 2018 The Author(s).

  11. Basin-Scale Assessment of the Land Surface Energy Budget in the National Centers for Environmental Prediction Operational and Research NLDAS-2 Systems

    This paper compares the annual and monthly components of the simulated energy budget from the North American Land Data Assimilation System phase 2 (NLDAS-2) with reference products over the domains of the 12 River Forecast Centers (RFCs) of the continental United States (CONUS). The simulations are calculated from both operational and research versions of NLDAS-2. The reference radiation components are obtained from the National Aeronautics and Space Administration Surface Radiation Budget product. The reference sensible and latent heat fluxes are obtained from a multitree ensemble method applied to gridded FLUXNET data from the Max Planck Institute, Germany. As these references are obtained from different data sources, they cannot fully close the energy budget, although the range of closure error is less than 15%formean annual results. The analysis here demonstrates the usefulness of basin-scale surface energy budget analysis for evaluating model skill and deficiencies. The operational (i.e., Noah, Mosaic, and VIC) and research (i.e., Noah-I and VIC4.0.5) NLDAS-2 land surface models exhibit similarities and differences in depicting basin-averaged energy components. For example, the energy components of the five models have similar seasonal cycles, but with different magnitudes. Generally, Noah and VIC overestimate (underestimate) sensible (latent) heat flux over several RFCs of the eastern CONUS. In contrast, Mosaic underestimates (overestimates) sensible (latent) heat flux over almost all 12 RFCs. The research Noah-I and VIC4.0.5 versions show moderate-to-large improvements (basin and model dependent) relative to their operational versions, which indicates likely pathways for future improvements in the operational NLDAS-2 system.

    For 40 years, the Pugwash Conference on Science and world affairs has been making unremitting efforts to achieve it main objectives the struggle to eliminate nuclear weapons, the elimination of wars and maintenance of world peace. The end of the Cold War vigorously encouraged world efforts in arms control and disarmament. On the day of exploding her first nuclear bomb in October 1964, China declared solemnly that it would never be the first to use nuclear weapons at any time under any circumstances. China has also committed unconditionally not to use nuclear weapons or threaten to use nuclear weapons against non-nuclear weapon states and nuclear free zones. China is the sole nuclear weapon state that has made this commitment, and she has kept her word. China is in favour of comprehensive nuclear test ban in the move towards complete nuclear disarmament, taking an active part in the CTBT negotiations in Geneva and contributing to the conclusion of a fair, reasonable, verifiable treaty of universal adherence and unlimited duration within this year

    Based on the analysis of the long process of negotiations for implementing the Treaty of Tlatelolco and its history during the last three decades, especially its influence on other regions of the world for stimulating the creation of new nuclear-weapon-free zones, the following conclusions were drawn: nuclear danger still persists; the end of Cold War implies the end of a nuclear threat; the nuclear fear should not become nuclear complacency and be accepted by international community; common security as the goal of international community should be recognised and definitive abolition of nuclear weapons should be sought; the Treaty of Tlatelolco represents the cornerstone for creating new nuclear-weapon-free zones; Treaties of Tlatelolco, Rarotonga, Bangkok and Pelindaba should be examples to be followed by other regions and groups of countries for creating new nuclear-weapon-free zones which should be recognised as very important phase in achieving a nuclear-weapon-free world and means for attaining an international regime of non-proliferation of weapons for mass destruction

    Full Text Available Operating of weapon on the tank is mostly by manually. It is not desired performance for a critical operation. An automatic control system is required to operate the weapon with the target while maintaining the accuracy. In this paper has designed an automatic weapon control system using object image proccessing. Various an image processing methods used to improve the weapon accuracy to obtain the intended target. The method used in digital image processing is the Camshift motion tracking method. This method is compared with the Lucas Canade motion tracking method. This comparison is conducted to found more precise results between the two methods. Results of object image processing are used to control the direction of the weapon that towards the desired goal. The results show that the implementation of the Lucas Canade motion tracking method using fire simulation tools have been successful. The performance of the Lucas Canade motion tracking methods is better than the CamShift method. Using Lucas Canade method for weapon controller is accordance with the purposes.

    2017-09-01

    Guns are associated with aggression. A landmark 1967 study showed that simply seeing a gun can increase aggression-called the "weapons effect." This meta-analysis integrates the findings of weapons effect studies conducted from 1967 to 2017. It includes 162 effect-size estimates from 78 independent studies involving 7,668 participants. The theoretical framework used to explain the weapons effect was the General Aggression Model (GAM), which proposes three routes to aggression-cognitive, affective, and arousal. The GAM also proposes that hostile appraisals can facilitate aggression. As predicted by the GAM, the mere presence of weapons increased aggressive thoughts, hostile appraisals, and aggression, suggesting a cognitive route from weapons to aggression. Weapons did not significantly increase angry feelings. Only one study tested the effects of weapons on arousal. These findings also contribute to the debate about social priming by showing that incidental exposure to a stimulus (weapon) can affect subsequent related behavior (aggression).

    Bozeman, William P; Teacher, Eric; Winslow, James E

    2012-12-01

    TASER (TASER International, Scottsdale, AZ) conducted electrical weapons (CEWs) are commonly used by law enforcement officers. Although animal studies have suggested that transcardiac CEW discharges may produce direct cardiac effects, this has not been demonstrated in human studies. This study sought to determine the incidence and outcomes of transcardiac CEW probe impact locations in a large series of actual CEW deployments. A multi-center database of consecutive CEW uses by law enforcement officers was retrospectively reviewed. Case report forms were independently reviewed by three investigators to identify cases with paired probe configurations potentially producing a transcardiac discharge vector. Descriptive analysis was performed and inter-rater reliability was assessed. Among 1201 total CEW uses, 813 included probe deployments and 178 cases had paired anterior probe impacts potentially capable of producing a transcardiac discharge vector. This represents 14.8% of all CEW uses (95% confidence interval [CI] 12.9-16.9%) and 21.9% of CEW uses in probe mode (95% CI 19.1-24.9%). Inter-rater agreement was very good, with kappa = 0.82. There were no immediate deaths in any cases (97.5% CI 0.0-0.3%) to suggest a cardiac dysrhythmia, including those with transcardiac discharge vector. CEW deployments with probe impact configurations capable of producing a transcardiac discharge occur in a minority of cases in field use conditions. None of these cases, transcardiac or otherwise, produced immediately fatal dysrhythmias. These data support the overall safety of CEWs and provide a benchmark estimate of the likelihood of transcardiac discharge vectors occurring in field use of CEWs. Copyright © 2012 Elsevier Inc.

    Pacific Northwest Laboratory (PNL) has measured the radionuclide concentration of short-lived debris from a radioactive cloud, produced by a nuclear weapons test conducted by the People's Republic of China on March 15, 1978. Analysis with a 40 cfm Sierra impactor showed that a large portion of the radioactivity was associated with relatively large particles. Surface air samples showed significant concentrations of 124 Sb. Samples of rain water from New York State showed that radioactivity arrived on the east coast at about the same time as peak debris levels were observed on the west coast. Highest concentrations of 131 I occurred along the Washington State--Canadian border

    Six classes of experiments form the base of a program of thermal neutron scattering at the Weapons Neutron Research (WNR) Facility. Three classes are to determine the average microscopic positions of atoms in materials and three are to determine the microscopic vibrations of these atoms. The first three classes concern (a) powder sample neutron diffraction, (b) small angle scattering, and (c) single crystal Laue diffraction. The second three concern (d) small kappa inelastic scattering, (e) scattering surface phonon measurements, and (f) line widths. An instrument to couple with the WNR pulsed source is briefly outlined for each experiment

    1992-01-01

    Global fields of precipitable water W from the special sensor microwave imager were compared with those from the European Center for Medium Range Weather Forecasts (ECMWF) model. They agree over most ocean areas; both data sets capture the two annual cycles examined and the interannual anomalies during an ENSO episode. They show significant differences in the dry air masses over the eastern tropical-subtropical oceans, particularly in the Southern Hemisphere. In these regions, comparisons with radiosonde data indicate that overestimation by the ECMWF model accounts for a large part of the differences. As a check on the W differences, surface-level specific humidity Q derived from W, using a statistical relation, was compared with Q from the ECMWF model. The differences in Q were found to be consistent with the differences in W, indirectly validating the Q-W relation. In both W and Q, SSMI was able to discern clearly the equatorial extension of the tongues of dry air in the eastern tropical ocean, while both ECMWF and climatological fields have reduced spatial gradients and weaker intensity.

  3. Spatial variations in microbial community composition in surface seawater from the ultra-oligotrophic center to rim of the South Pacific Gyre.

    Full Text Available Surface seawater in the South Pacific Gyre (SPG is one of the cleanest oceanic environments on earth, and the photosynthetic primary production is extremely low. Despite the ecological significance of the largest aquatic desert on our planet, microbial community composition in the ultra-oligotrophic seawater remain largely unknown. In this study, we collected surface seawater along a southern transect of the SPG during the Integrated Ocean Drilling Program (IODP Expedition 329. Samples from four distinct sites (Sites U1368, U1369, U1370 and U1371 were examined, representing ~5400 kilometers of transect line from the gyre heart to the edge area. Real-time PCR analysis showed 16S rRNA gene abundance in the gyre seawater, ranging from 5.96×10(5 to 2.55×10(6 copies ml(-1 for Bacteria and 1.17×10(3 to 1.90×10(4 copies ml(-1 for Archaea. The results obtained by statistic analyses of 16S rRNA gene clone libraries revealed the community composition in the southern SPG area: diversity richness estimators in the gyre center (Sites U1368 & U1369 are generally lower than those at sites in the gyre edge (Sites U1370 & U1371 and their community structures are clearly distinguishable. Phylogenetic analysis showed the predominance of Proteobacteria (especially Alphaproteobacteria and Cyanobacteria in bacterial 16S rRNA gene clone libraries, whereas phylotypes of Betaproteobacteria were only detected in the central gyre. Archaeal 16S rRNA genes in the clone libraries were predominated by the sequences of Marine Group II within the Euryarchaeota, and the Crenarchaeota sequences were rarely detected, which is consistent with the real-time PCR data (only 9.9 to 22.1 copies ml(-1. We also performed cultivation of heterotrophic microbes onboard, resulting in 18.9% of phylogenetically distinct bacterial isolates at least at the species level. Our results suggest that the distribution and diversity of microbial communities in the SPG surface seawater are closely

  4. Chemical and biological weapons in the 'new wars'.

    Science.gov (United States)

    Ilchmann, Kai; Revill, James

    2014-09-01

    The strategic use of disease and poison in warfare has been subject to a longstanding and cross-cultural taboo that condemns the hostile exploitation of poisons and disease as the act of a pariah. In short, biological and chemical weapons are simply not fair game. The normative opprobrium is, however, not fixed, but context dependent and, as a social phenomenon, remains subject to erosion by social (or more specifically, antisocial) actors. The cross cultural understanding that fighting with poisons and disease is reprehensible, that they are taboo, is codified through a web of interconnected measures, principal amongst these are the 1925 Geneva Protocol; the Biological Weapons Convention; and the Chemical Weapons Convention. Whilst these treaties have weathered the storm of international events reasonably well, their continued health is premised on their being 'tended to' in the face of contextual changes, particularly facing changes in science and technology, as well as the changed nature and character of conflict. This article looks at the potential for normative erosion of the norm against chemical and biological weapons in the face of these contextual changes and the creeping legitimization of chemical and biological weapons.

  5. Civil nuclear energy and the proliferation of nuclear weapons

    International Nuclear Information System (INIS)

    1990-04-01

    The issue of whether civil nuclear programmes contribute to the risk of proliferation of nuclear weapons has been discussed since civil programmes were first considered, and has always complicated public attitudes to civil nuclear energy. This paper seeks to define the extent to which there is such ''linkage''. It does not deal with the linkages that exist between nuclear weapons and other industries and activities - for example, those involved in weapons delivery systems -since these are not within the Uranium Institute's area of competence. Linkage concerns regarding civil nuclear programmes arise primarily over the possibility of their being used to produce highly enriched uranium or plutonium for use in weapons. The technologies which can give rise directly to these materials are therefore ''sensitive'' in proliferation terms. Linkage may also arise through the relevant experience of the trained workforce. Such linkage is, however, limited by institutional, technical and economic factors. First, important institutional constraints on using a civil programme for military purposes exist in the form of a network of bilateral agreements and international treaties - most particularly the Nuclear Non-Proliferation Treaty - and the international safeguards inspections. Secondly, without access to the technologies of enrichment or reprocessing, the fissile material needed for an explosive cannot be obtained from any plant or process used to produce electricity. Finally, establishing a civil programme - with equipment whose design is optimized for electricity production - in order to develop weapons is an expensive route compared to specialized facilities.

    This paper examines international treaties in relation to the threat or use of nuclear weapons including the 1968 Nuclear Non-Proliferation Treaty and the 1996 Comprehensive Test Ban Treaty. It can be concluded that the effect of the aforesaid international treaties is still in doubt without explicit enforcement mechanisms and penalty for non-compliance. This paper also reviews the International Court of Justice's advisory opinion on the legality of the threat or use of nuclear weapons and comments that a clear explanation on the legality of use of nuclear weapons in 'extreme circumstances of self-defence' is required. Examples from current state practice in relation to nuclear non-proliferation efforts are also provided, with special attention to China, North Korea and Iran. This paper suggests that China as a leader of developing countries should extend its efforts on nuclear non-proliferation and conduct communication between North Korea and Iran and other nuclear weapons states to reduce or prohibit nuclear weapons.

  7. Hitler's bomb: the secret story of Germans' attempts to get the nuclear weapon

    Karlsch, Rainer

    2007-01-01

    In this historical book, the author claims to have evidence concerning the development and testing of a possible 'nuclear weapon' by Nazi Germany in 1945. The 'weapon' in question is not alleged to be a standard nuclear weapon powered by nuclear fission, but something closer to either a radiological weapon (a so-called 'dirty bomb') or a hybrid-nuclear fusion weapon. Its new evidence is concerned primarily with the parts of the German nuclear energy project (an attempted clandestine scientific effort led by Germany to develop and produce atomic weapons during World War II) under Kurt Diebner, a German nuclear physicist who directed and administrated the project

    Emergence of and the motivations behind the concept of nuclear weapon free zone, the conceptual linkage between the nuclear weapon free zone and the Non-Proliferation Treaty and the problems involved in the implementation of nuclear weapon free zone proposals put forward from time to time are discussed. Pakistan's proposal for a nuclear weapon free zone in South Asia, motivations behind the proposal, and India's response to it are examined. It is pointed out that both the NPT and nuclear weapon free zone indirectly grant a certain amount of legitimacy to the use of nuclear weapons. (M.G.B.)

  9. Canadian--American relations and the nuclear weapons controversy, 1958--1963

    Ghent, J.M.

    1976-01-01

    This study attempts to explain the nuclear weapons controversy as it developed between 1958 and 1963. The nuclear controversy centered around Canada's acceptance of a nuclear role, within the American alliance system, for the Canadian armed forces. In the period 1958-1959, when the critical weapons decisions were being taken, Canadian political authorities lost control of the policy-making process, permitting the Canadian and American military bureacracies to initiate nuclear plans suited to their common needs and objectives. Prime Minister Diefenbaker's reluctance to arm the systems acquired by transborder bureaucratic coalition is also re-examined. Previous analysts have regarded the government's hesitations over nuclear weapons as the product of Diefenbaker's personal antagonism towards President Kennedy or as a futile attempt to reverse the process of continental integration. The opening of the Kennedy papers reveals the degree to which Diefenbaker was committed to close Canadian-American cooperation and the effort he made to overcome the president's hostility towards him. This study emphasizes the importance of Diefenbaker's sensitivity to public, parliamentary, and cabinet opposition to nuclear arms. The secret U.S. demand for nuclear bases in Labrador and Newfoundland is revealed. Thus the question of nuclear storage in Canada for Canadian forces was complicated by U.S. insistence that Canada simultaneously provide nuclear storage for the strategic forces of the U.S. Finally, the extent of American responsibility for Diefenbaker's demise is re-assessed, and the conclusion is reached that the U.S., through Canadian-American military interaction and the initiative of the ambassador in Ottawa, did in fact help to bring down the government of Canada

  10. Hazards of chemical weapons release during war: new perspectives.

    Science.gov (United States)

    Reutter, S

    1999-01-01

    The two major threat classes of chemical weapons are mustard gas and the nerve agents, and this has not changed in over 50 years. Both types are commonly called gases, but they are actually liquids that are not remarkably volatile. These agents were designed specifically to harm people by any route of exposure and to be effective at low doses. Mustard gas was used in World War I, and the nerve agents were developed shortly before, during, and after World War II. Our perception of the potency of chemical weapons has changed, as well as our concern over potential effects of prolonged exposures to low doses and potential target populations that include women and children. Many of the toxicologic studies and human toxicity estimates for both mustard and nerve agents were designed for the purpose of quickly developing maximal casualties in the least sensitive male soldier. The "toxicity" of the chemical weapons has not changed, but our perception of "toxicity" has. PMID:10585902

  11. Environmental Restoration Strategic Plan. Remediating the nuclear weapons complex

    International Nuclear Information System (INIS)

    1995-08-01

    With the end of the cold war, the US has a reduced need for nuclear weapons production. In response, the Department of Energy has redirected resources from weapons production to weapons dismantlement and environmental remediation. To this end, in November 1989, the US Department of Energy (DOE) established the Office of Environmental Restoration and Waste Management (renamed the Office of Environmental Management in 1994). It was created to bring under a central authority the management of radioactive and hazardous wastes at DOE sites and inactive or shut down facilities. The Environmental Restoration Program, a major component of DOE's Environmental Management Program, is responsible for the remediation and management of contaminated environmental media (e.g., soil, groundwater, sediments) and the decommissioning of facilities and structures at 130 sites in over 30 states and territories

  12. Open-area concealed-weapon detection system

    Science.gov (United States)

    Pati, P.; Mather, P.

    2011-06-01

    Concealed Weapon Detection (CWD) has become a significant challenge to present day security needs; individuals carrying weapons into airplanes, schools, and secured establishments are threat to public security. Although controlled screening, of people for concealed weapons, has been employed in many establishments, procedures and equipment are designed to work in restricted environments like airport passport control, military checkpoints, hospitals, school and university entrance. Furthermore, screening systems do not effectively decipher between threat and non-threat metal objects, thus leading to high rate of false alarms which can become a liability to daily operational needs of establishments. Therefore, the design and development of a new CWD system to operate in a large open area environment with large numbers of people reduced incidences of false alarms and increased location accuracy is essential.

    International Nuclear Information System (INIS)

    Deplech, M.; Tommasi, J.; Zaetta, A.

    2000-01-01

    In the frame work of the AIDA/MOX phase I/I/ program (1994-1997) between France and Russia, the disposition of plutonium in reactors was studied. The LWR (Light Water Reactor), FR (Fast reactors), CANDU (Heavy Water Reactors), HTR (High Temperature Reactors) options for using excess dismantled weapons plutonium for peaceful commercial nuclear power generating purposes offer some advantages over the remaining options (storage). The AIDA/MOX phase 1 program covers different topics, among which are the neutronic aspects of loading reactors with weapons-grade plutonium. The conclusions are that the weapon plutonium consumption is similar in the different type of reactors. However, the use of inert matrices allows to increase the mass balance for a same denaturing level. The use of Thorium as a matrix or special isotopes to increase the proliferation resistance prove to be insufficient. (author)

    This communication addresses real-time weapon classification by analysis of asynchronous acoustic data, collected from microphones on a sensor network. The weapon classification algorithm consists of two parts: (i) feature extraction from time-series data using symbolic dynamic filtering (SDF), and (ii) pattern classification based on the extracted features using the language measure (LM) and support vector machine (SVM). The proposed algorithm has been tested on field data, generated by firing of two types of rifles. The results of analysis demonstrate high accuracy and fast execution of the pattern classification algorithm with low memory requirements. Potential applications include simultaneous shooter localization and weapon classification with soldier-wearable networked sensors. (rapid communication)

    2008-01-01

    The Chemical Weapons Convention (CWC) was drafted with the recognition that it is impossible to envision every way in which toxic chemicals might be used for aggressive purposes. As terrorist organizations and rogue states replace the major powers as the most likely candidates to employ chemical weapons, the agents of choice may differ from those developed for battlefield use. Twenty- first century chemical warfare may target civilians or agricultural production, and clandestine production-facilities may manufacture toxic agents from chemical precursors, not monitored under the CWC control regime. The effects (on CWC implementation) of changing industrial technologies, including ongoing developments in chemical process technology, dual-use industrial chemicals, and rapid methods for discovering biologically active chemicals, are considerable Also considered is how commercial technologies could be misused for the development of novel chemical weapons, and how such abuses might be detected and monitored.

    2018-01-01

    Full Text Available In recent wars, there is an increasing trend that unmanned aerial vehicles (UAVs are utilized to conduct military attacking missions. In this paper, we investigate a novel multidepot UAV routing problem with consideration of weapon configuration in the UAV and the attacking time window of the target. A mixed-integer linear programming model is developed to jointly optimize three kinds of decisions: the weapon configuration strategy in the UAV, the routing strategy of target, and the allocation strategy of weapons to targets. An adaptive large neighborhood search (ALNS algorithm is proposed for solving the problem, which is tested by randomly generated instances covering the small, medium, and large sizes. Experimental results confirm the effectiveness and robustness of the proposed ALNS algorithm.

  17. Canadians, nuclear weapons, and the Cold War security dilemma

    Eaton, M.A.

    2007-01-01

    This dissertation provides a history of Canadian ideas about nuclear weapons from the late 1950s until the end of the Trudeau era in 1984. Throughout this period, Canadians reacted to the insecurity they felt in the world around them by expressing many conflicting, often irreconcilable views about a range of nuclear weapon issues, including Canada's acquisition of nuclear warheads in 1963, the U.S. ABM program in the 1960s and early 1970s, the role of Canadian nuclear technology in the development of India's first nuclear explosion, and the Trudeau government's decision to allow the U.S. military to test cruise missiles in northern Canada The dissertation concludes with an examination of the emergence of a broadly-based, increasingly mainstream and influential anti-nuclear movement in the early 1980s, the clearest manifestation of the insecurity Canadians experienced at the time. .The nuclear debates examined in this dissertation reveal that Canadians were divided over nuclear weapons, nuclear strategy, the arms race, proliferation, and arms control and disarmament. In particular, they came to fundamentally different conclusions about how Canada's nuclear weapon policies, and its support for the nuclear policies of its alliances, would contribute to international stability and order. Some believed that their security rested on the maintenance of a strong Western nuclear deterrent and supported Canada contributing to its credibility; others believed that the constant modernisation of nuclear arsenals fuelled by the superpower arms race posed a serious threat to their security. This conceptual dilemma-the security through nuclear strength argument versus the fear that the quest for security through quantitative and qualitative improvements of nuclear stockpiles increased the likelihood of nuclear war-left Canadians divided over the value and utility of nuclear weapons and the strategies developed around them. At the same time, Canadians' ideas about nuclear weapons

    1994-04-01

    This report summarizes the findings of a nationwide survey of public perceptions of nuclear weapons in the post-cold war environment. Participants included 1,301 members of the general public, 1,155 randomly selected members of the Union of Concerned Scientists, and 1,226 employees randomly selected from the technical staffs of four DOE national laboratories. A majority of respondents from all three samples perceived the post-cold war security environment to pose increased likelihood of nuclear war, nuclear proliferation, and nuclear terrorism. Public perceptions of nuclear weapons threats, risks, utilities, and benefits were found to systematically affect nuclear weapons policy preferences in predictable ways. Highly significant relationships were also found between public trust and nuclear weapons policy preferences. As public trust and official government information about nuclear weapons increased, perceptions of nuclear weapons management risks decreased and perceptions of nuclear weapons utilities and benefits increased. A majority of respondents favored decreasing funding for: (1) developing and testing new nuclear weapons; (2) maintaining existing nuclear weapons, and (3) maintaining the ability to develop and improve nuclear weapons. Substantial support was found among all three groups for increasing funding for: (1) enhancing nuclear weapons safety; (2) training nuclear weapons personnel; (3) preventing nuclear proliferation; and (4) preventing nuclear terrorism. Most respondents considered nuclear weapons to be a persistent feature of the post-cold war security environment.

    This report discusses DOE's efforts to correct the environmental problems facing the nuclear weapons complex. It focuses on three main points. First, the weapons complex faces a variety of serious and costly environmental problems. Second, during the past year, DOE has made some important changes to its organization that should help change its management focus from one that emphasizes materials production to one that more clearly focuses on environmental concerns. Third, because resolution of DOE's environmental problems will require considerable resources during a period of budgetary constraints, it is imperative that DOE have internal controls in place to ensure that resources are spent efficiently

    The detection and identification of concealed weapons is an extremely hard problem due to the weak signature of the target buried within the much stronger signal from the human body. This paper furthers the automatic detection and identification of concealed weapons by proposing the use of an effective approach to obtain the resonant frequencies in a measurement. The technique, based on Matrix Pencil, a scheme for model based parameter estimation also provides amplitude information, hence providing a level of confidence in the results. Of specific interest is the fact that Matrix Pencil is based on a singular value decomposition, making the scheme robust against noise.

    International Nuclear Information System (INIS)

    Durand, Daniel; Nivet, Roland

    2017-01-01

    A first article notices that modernisation of nuclear weapons are resumed with the emergence of new nuclear temptations: ambitious modernisation programme in the USA, catching-up race by Russia to be able to pierce antimissile defences, Chinese modernisation, renewal of the British Trident programme, doubling of nuclear military budgets in France, developments in India and Pakistan. However, the author discusses the possible emergence of new opportunities for a nuclear disarmament: humanitarian ICAN campaign for a treaty of interdiction of nuclear weapons. He highlights the need of a debate in France on these issues even though no politician dares to take a strong position in favour of nuclear disarmament. In a third article, a member of an activist association shows that, after the adoption of a U N resolution on favour of the elaboration of a treaty of interdiction of nuclear weapons, reaching such a treaty is possible. The action of civil society seems necessary

  11. The tale of the shrinking weapon: seasonal changes in nutrition affect weapon size and sexual dimorphism, but not contemporary evolution.

    Science.gov (United States)

    Miller, C W; McDonald, G C; Moore, A J

    2016-11-01

    Sexually selected traits are often highly variable in size within populations due to their close link with the physical condition of individuals. Nutrition has a large impact on physical condition, and thus, any seasonal changes in nutritional quality are predicted to alter the average size of sexually selected traits as well as the degree of sexual dimorphism in populations. However, although traits affected by mate choice are well studied, we have a surprising lack of knowledge of how natural variation in nutrition affects the expression of sexually selected weapons and sexual dimorphism. Further, few studies explicitly test for differences in the heritability and mean-scaled evolvability of sexually selected traits across conditions. We studied Narnia femorata (Hemiptera: Coreidae), an insect where males use their hind legs as weapons and the femurs are enlarged, to understand the extent to which weapon expression, sexual dimorphism and evolvability change across the actual range of nutrition available in the wild. We found that insects raised on a poor diet (cactus without fruit) are nearly monomorphic, whereas those raised on a high-quality diet (cactus with ripe fruit) are distinctly sexually dimorphic via the expression of large hind leg weapons in males. Contrary to our expectations, we found little evidence of a potential for evolutionary change for any trait measured. Thus, although we show weapons are highly condition dependent, and changes in weapon expression and dimorphism could alter evolutionary dynamics, our populations are unlikely to experience further evolutionary changes under current conditions. © 2016 European Society For Evolutionary Biology.

  17. Surplus weapons-grade plutonium: a resource for exploring and terraforming Mars

    Energy Technology Data Exchange (ETDEWEB)

    Muscatello, A.C.; Houts, M.G.

    1996-12-31

    With the end of the Cold War, greater than 100 metric tons (MT) of weapons-grade plutonium (WGPu) have become surplus to defense needs in the United States and the Former Soviet Union. This paper is a proposal for an option for WGPu disposition, i.e., use of the plutonium as a fuel for nuclear reactors for Mars exploration and eventual terraforming. WGPu was used in nuclear weapons because it has a much smaller critical mass than highly enriched uranium, allowing lighter weapons with consequent longer ranges. Similarly, WGPu reactors would also require smaller amounts of fuel to attain a critical mass, making the reactor much lighter overall and resulting in large savings in launch costs. The greater than 100 MT of WGPu would generate about 1000 billion kilowatt hours of heat energy, much of which could be converted into electricity. The waste heat would also be useful to a Martian outpost or colony. A potential way of getting the WGPu reactors into space is a large gas gun like that being developed at the Lawrence Livermore National Laboratory to orbit materials by achieving high velocity at the surface, greatly reducing launch costs and enhancing reliability. Reactor components would be launched on conventional rockets or space shuttles, the reactor fuel rods would be injected into orbit using the gas gun, and the reactor would be assembled in space. Implementation of this proposal would allow disposition of a serious, expensive problem on earth by removing the WGPu from the planet and simultaneously provide a very large energy resource for Mars exploration and terraforming.

Reactor components would be launched on conventional rockets or space shuttles, the reactor fuel rods would be injected into orbit using the gas gun, and the reactor would be assembled in space. Implementation of this proposal would allow disposition of a serious, expensive problem on earth by removing the WGPu from the planet and simultaneously provide a very large energy resource for Mars exploration and terraforming

    , contained in MOX-fuel, with zirconium alloys and stainless steels is not known. The knowledge of its acceptable content in fuel will permit to choose an optimum variant of plutonium purification from gallium. Therewith, it is possible to guess that the acceptable content of gallium in plutonium dioxide used for fabrication of the fuel for the reactors on fast and thermal neutrons can be different. To furnish the environmental safety of MOX-fuel during its storage, transportation and production, plutonium dioxide must be refined from americium-241, which is being accumulated in weapons-grade plutonium on the account of decaying plutonium-241. At present, in Russia there are several technologies under study, which principally allow to resolve the tasks mentioned above. All technologies have advantages and disadvantages, but none of them can be considered complete since in each one there are fields that are not studied sufficiently, and mainly, in many processes a final result, the quality of plutonium dioxide, is not assessed. Detailed description of some technologies of the conversion is included. These are being studied in scientific centers at MINATOM

  4. Disposition of weapons-grade plutonium in Westinghouse reactors

    International Nuclear Information System (INIS)

    Alsaed, A.A.; Adams, M.

    1998-03-01

    The authors have studied the feasibility of using weapons-grade plutonium in the form of mixed-oxide (MOX) fuel in existing Westinghouse reactors. They have designed three transition Cycles from an all LEU core to a partial MOX core. They found that four-loop Westinghouse reactors such as the Vogtle power plant are capable of handling up to 45 percent weapons-grade MOX loading without any modifications. The authors have also designed two kinds of weapons-grade MOX assemblies with three enrichments per assembly and four total enrichments. Wet annular burnable absorber (WABA) rods were used in all the MOX feed assemblies, some burned MOX assemblies, and some LEU feed assemblies. Integral fuel burnable absorber (IFBA) was used in the rest of the LEU feed assemblies. The average discharge burnup of MOX assemblies was over 47,000 MWD/MTM, which is more than enough to meet the open-quotes spent fuel standard.close quotes One unit is capable of consuming 0.462 MT of weapons-grade plutonium per year. Preliminary analyses showed that important reactor physics parameters for the three transitions cycles are comparable to those of LEU cores including boron levels, reactivity coefficients, peaking factors, and shutdown margins. Further transient analyses will need to be performed

  6. Internationalization to prevent the spread of nuclear weapons

    International Nuclear Information System (INIS)

    1980-01-01

    The recent International Nuclear Fuel Cycle Evaluation (INFCE) has concluded that, in a world in which an increasing number of countries are using nuclear energy for peaceful purposes, no technical ways exist to prevent the spread of nuclear weapons. Non-proliferation is a political problem and must, therefore, be solved by political means. The reasons why countries want nuclear weapons - whether to meet their real or perceived security requirements or for political prestige - must be removed. Resolution of regional conflicts would diminish the stimulus for proliferation, while significant nuclear disarmament measures would de-emphasize the role of nuclear weapons in international politics. Meanwhile, institutional arrangements could minimize the risks of nuclear weapon proliferation. One such arrangement could be the internationalization of the sensitive, that is, the most proliferation-prone, elements of the nuclear fuel cycle. This book analyses some of the political, economic, technical and legal issues involved in internationalizing the nuclear fuel cycle. It consists of two parts. Part I is SIPRI's (Stockholm International Peace Research Institute) evaluation of the advantages, as well as the weaknesses, of the existing proposals for internationalization. Part II contains the papers contributed to the SIPRI symposium on 'internationalization of the nuclear fuel cycle', which was held in October/ November 1979. (author)

  7. Nuclear electric power and the proliferation of nuclear weapon states

    International Nuclear Information System (INIS)

    Walske, C.

    1977-01-01

    Control and elimination of the strategic nuclear weapons held by the nuclear weapon states remains the central problem in the arms control and disarmament field. Whether the proliferation of nations with nuclear weapons can be stopped is dubious. A sovereign nation will launch a nuclear weapons program if it has the motivation and resource. Motivation depends on military and political considerations. The necessary resources are economic and technological. Conditions in some sovereign states explain this issue. A survey of commercial nuclear power programs outside the USA lists 45 countries using or planning to use nuclear reactors for power generation. There are currently 112 reactors now operating outside the United States, 117 more under construction, 60 on order, and 180 planned. The U. S. as of December 1976 has 64 operating reactors, 72 under construction, 84 on order, and 8 planned. Nuclear trade and export policies are discussed. In this article, Mr. Walske says that American industry is convinced that the need for nuclear energy abroad is more urgent than in the United States; that in the long run, the breeder reactor must be developed to enable the supply of nuclear fuel to last for centuries; and that the experience of American industry abroad has convinced it that emphasis on restrictive, denial type policies will almost certainly fail--a collapse of what has been gained through the test ban treaty and the nonproliferation treaty

  11. Civil nuclear energy and the proliferation of nuclear weapons

    International Nuclear Information System (INIS)

    1990-04-01

    The issue of whether civil nuclear programmes contribute to the risk of proliferation of nuclear weapons has been discussed since civil programmes were first considered, and has always complicated public attitudes to civil nuclear energy. This paper seeks to define the extent to which there is such 'linkage'. Linkage concerns arise primarily over the possibility of their being used to produce highly enriched uranium or plutonium for use in weapons. Linkage may also arise through the relevant experience of the trained workforce. Such linkage is, however, limited by institutional, technical and economic factors. First important institutional constraints on using a civil programme for military purposes exist in the form of a network of bilateral agreements and international treaties - most particularly the Nuclear Non-Proliferation Treaty - and the international safeguards inspections. Secondly, without access to the technologies of enrichment or reprocessing, the fissile material needed for an explosive cannot be obtained from any plant or process used to produce electricity. Even enrichment and reprocessing, as normally used in electricity programmes, do not give rise to the materials used in weapons. Finally, establishing a civil programme - with equipment whose design is optimized for electricity production - in order to develop weapons is an expensive route compared to specialized facilities.

    Science.gov (United States)

    2014-03-01

    Nuclear weapons pose a combination of political and ethical dilemmas the solution to which has not been found. On one hand, in the view of both US government leaders and US allies, nuclear deterrence continues to play an essential part in the US role as the ultimate source of military strength for the alliances among the major democratic countries. It also continues to be in demand by countries that believe themselves to be isolated and threatened. On the other hand, nuclear weapons, besides being effective deterrents, can cause unprecedented loss of life and risk the demise of civilizations. No ban or technical precaution could prevent the rebuilding of nuclear weapons in a crisis. No diplomatic arrangement to date has erased the threat of invasion and war in the world. Only the abandonment of war and the threat of war as instruments of policy can make nuclear weapons obsolete. The slow, halting, risky road to that end remains the only hope for a world in which lasting solutions to the nuclear dilemmas are possible.

  17. Between Allies and Rivals: Turkey, Nuclear Weapons, and BMD

    International Nuclear Information System (INIS)

    Kibaroglu, Mustafa

    2014-01-01

    This paper discusses Turkey's attitudes vis-a-vis nuclear weapons and Ballistic Missile Defense in the light of recent developments in the Iranian nuclear program and NATO's evolving concept of extended deterrence. On the one hand, the long-standing forward deployment of US tactical nuclear weapons in Turkey and the country's role in the US Phased Adaptive Approach BMD architecture are still considered to be key elements of national security. On the other, security guarantees offered to Turkey by NATO and the US appear less and less credible in the face of rising regional threats. As this paper shows, there is a growing gap between official policy and public perceptions inside Turkey vis-a-vis the US, Iran, and nuclear weapons, as well as a growing Turkish aspiration to autonomy in its security and defense policy. While one should not expect Turkey to develop nuclear weapons anytime soon, an unchecked Iranian regional power could bring Ankara to hedge its bets in the long term. Turkey's controversial recent decision to buy a Chinese system for its national air and missile defense rather than European or US equipment should be seen in the light of this search for autonomy.

    Extensive exposure to chemical weapons such as mustard gas, nerve gas and cyanide caused high mortality, morbidity, injuries, and chronic side effects in vital organs, especially the respiratory tract. Chemical weapons were heavily used by Iraq against Iranian soldiers between 1984-1986. Then, against the Iraqi Kurd in Sheikh Wasan and Balisan valley, during April 1987 and in Halabja on 18th March 1988. Reports suggested that as many as 2.9 percent of the Kurdish population have been exposed to chemical weapon at some level. This case report describes a Kurdish lady who was exposed to mustard gas during a chemical attack in sheikh Wasan in Iraq. A thirty two years old woman wearing black clothes presented to our center at 1999 complaining from shortness of breath (SOB). Her condition started 12 years ago when the Iraqi Government attacked her village Sheikh Wasan by Chemical weapons which included Mustard gas and nerve gases such as Sarin, Tabun and VX in April 1987. She described how the gas smelled like garlic as it spread over the village. During the attack she suffered from sever SOB, cough, skin burn and eyes irritation and lacrimation. After several days of being without medical care, she received some medical attention by local medical staff at the area because the Iraqi authorities at that time refused and prohibited them from management at the major hospitals. After several days when she returned back to her home she found that several members of her family have died during the exposure to chemical gases. Among the dead people were her husband, her son, her brother in addition to other second and third degree relatives. Since that time she suffered from repeated attacks of cough and SOB and wheezing that were increased by exertion and cold exposure. The attacks were more sever with time and the SOB has interfered with her daily activity and even lastly she was suffering from SOB at rest and during sleep that made her unable to sleep lying down.

To perform a content analysis of the depictions of violence and weapon carrying in music videos, including 5 genres of music (rock, rap, adult contemporary, rhythm and blues, and country), from 4 television networks and to analyze the degree of sexuality or eroticism portrayed in each video and its association with violence and weapon carrying, as an indicator of the desirability of violent behaviors. Five hundred eighteen videos were recorded during randomly selected days and times of the day from the Music Television, Video Hits One, Black Entertainment Television, and Country Music Television networks. Four female and 4 male observers aged 17 to 24 years were trained to use a standardized content analysis instrument. Interobserver reliability testing resulted in a mean (+/- SD) percentage agreement of 89.25% +/- 7.10% and a mean (+/- SD) kappa of 0.73 +/- 0.20.

  15. US and Russia face urgent decisions on weapons plutonium

    International Nuclear Information System (INIS)

    Hileman, B.

    1994-01-01

    Surplus plutonium poses a ''clear and present danger to national and international security,'' warns a National Academy of Sciences (NAS) study released in January, titled ''The Management and Disposition of Excess Weapons Plutonium.'' Over the past few years, many different methods of disposing of plutonium have been proposed. They range from shooting it into the Sun with missiles, to deep-seabed disposal, to fissioning it within a new generation of nuclear reactors. The NAS report rejects most of the methods suggested so far, but does recommend pursuing two of the options. One is to incorporate the plutonium in mixed-oxide fuel, a mixture of plutonium and uranium oxides, and use it to fuel commercial nuclear reactors. The other is to mix the plutonium with high-level waste and molten glass and mold the resulting material into large glass logs for eventual geologic disposal. Both are discussed here. The panel that wrote the NAS study is a standing committee called the Committee on International Security ampersand Arms Control. It suggests steps that should be taken now to guard supplies of plutonium removed from weapons. One step is bilateral US-Russian monitoring of warhead dismantlement. Others include setting up secure interim storage for the fissile materials and establishing an international monitoring system to verify the stockpiles and ensure that materials are not withdrawn for use in new weapons. The panel also urges Russia to stop producing fissile weapons materials and both countries to commit a very large fraction of their plutonium and highly enriched uranium from dismantled weapons to nonaggressive uses. The US and Russia have already made initial moves to accomplish these goals but have not fully implemented any of them

  16. From Russian weapons grade plutonium to MOX fuel

    International Nuclear Information System (INIS)

    Braehler, G.; Kudriavtsev, E.G.; Seyve, C.

    1997-01-01

    The April 1996, G7 Moscow Summit on nuclear matters provided a political framework for one of the most current significant challenges: ensuring a consistent answer to the weapons grade fissile material disposition issue resulting from the disarmament effort engaged by both the USA and Russia. International technical assessments have showed that the transformation of Weapons grade Plutonium in MOX fuel is a very efficient, safe, non proliferant and economically effective solution. In this regard, COGEMA and SIEMENS, have set up a consistent technical program properly addressing incineration of weapons grade plutonium in MOX fuels. The leading point of this program would be the construction of a Weapons grade Plutonium dedicated MOX fabrication plant in Russia. Such a plant would be based on the COGEMA-SIEMENS industrial capabilities and experience. This facility would be operated by MINATOM which is the partner for COGEMA-SIEMENS. MINATOM is in charge of coordination of the activity of the Russian research and construction institutes. The project take in account international standards for non-proliferation, safety and waste management. France and Germany officials reasserted this position during their last bilateral summits held in Fribourg in February and in Dijon in June 1996. MINATOM and the whole Russian nuclear community have already expressed their interest to cooperate with COGEMA-SIEMENS in the MOX field. This follows governmental-level agreements signed in 1992 by French, German and Russian officials. For years, Russia has been dealing with research and development on MOX fabrication and utilization. So, the COGEMA-SIEMENS MOX proposal gives a realistic answer to the management of weapons grade plutonium with regard to the technical, industrial, cost and schedule factors. (author)

  17. Measurement techniques for the verification of excess weapons materials

    International Nuclear Information System (INIS)

    Tape, J.W.; Eccleston, G.W.; Yates, M.A.

    1998-01-01

    The end of the superpower arms race has resulted in an unprecedented reduction in stockpiles of deployed nuclear weapons. Numerous proposals have been put forward and actions have been taken to ensure the irreversibility of nuclear arms reductions, including unilateral initiatives such as those made by President Clinton in September 1993 to place fissile materials no longer needed for a deterrent under international inspection, and bilateral and multilateral measures currently being negotiated. For the technologist, there is a unique opportunity to develop the technical means to monitor nuclear materials that have been declared excess to nuclear weapons programs, to provide confidence that reductions are taking place and that the released materials are not being used again for nuclear explosive programs. However, because of the sensitive nature of these materials, a fundamental conflict exists between the desire to know that the bulk materials or weapon components in fact represent evidence of warhead reductions, and treaty commitments and national laws that require the protection of weapons design information. This conflict presents a unique challenge to technologists. The flow of excess weapons materials, from deployed warheads through storage, disassembly, component storage, conversion to bulk forms, and disposition, will be described in general terms. Measurement approaches based on the detection of passive or induced radiation will be discussed along with the requirement to protect sensitive information from release to unauthorized parties. Possible uses of measurement methods to assist in the verification of arms reductions will be described. The concept of measuring attributes of items rather than quantitative mass-based inventory verification will be discussed along with associated information-barrier concepts required to protect sensitive information

    Base-line and long-term monitoring of water resources of the National Guard Training Center at Fort Indiantown Gap in south-central Pennsylvania began in 2002. Results of continuous monitoring of streamflow and turbidity and monthly and stormflow water-quality samples from two continuous-record long-term stream sites, periodic collection of water-quality samples from five miscellaneous stream sites, and annual collection of biological data from 2002 to 2005 at 27 sites are discussed. In addition, results from a stream-geomorphic analysis and classification and a regional groundwater-flow model are included. Streamflow at the facility was above normal for the 2003 through 2005 water years and extremely high-flow events occurred in 2003 and in 2004. Water-quality samples were analyzed for nutrients, sediments, metals, major ions, pesticides, volatile and semi-volatile organic compounds, and explosives. Results indicated no exceedances for any constituent (except iron) above the primary and secondary drinking-water standards or health-advisory levels set by the U.S. Environmental Protection Agency. Iron concentrations were naturally elevated in the groundwater within the watershed because of bedrock lithology. The majority of the constituents were at or below the method detection limit. Sediment loads were dominated by precipitation due to the remnants of Hurricane Ivan in September 2004. More than 60 percent of the sediment load measured during the entire study was transported past the streamgage in just 2 days during that event. Habitat and aquatic-invertebrate data were collected in the summers of 2002-05, and fish data were collected in 2004. Although 2002 was a drought year, 2003-05 were above-normal flow years. Results indicated a wide diversity in invertebrates, good numbers of taxa (distinct organisms), and on the basis of a combination of metrics, the majority of the 27 sites indicated no or slight impairment. Fish-metric data from 25 sites indicated results

    Toxins are hazardous biochemical compounds derived from bacteria, fungi, or plants. Some have mechanisms of action and physical properties that make them amenable for use as potential warfare agents. Currently, some toxins are classified as potential biological weapons, although they have several differences from classic living bio-terror pathogens and some similarities to manmade chemical warfare agents. This review focuses on category A and B bio-terror toxins recognized by the Centers for Disease Control and Prevention: Botulinum neurotoxin, staphylococcal enterotoxin B, Clostridium perfringens epsilon toxin, and ricin. Their derivation, pathogenesis, mechanism of action, associated clinical signs and symptoms, diagnosis, and treatment are discussed in detail. Given their expected covert use, the primary diagnostic challenge in toxin exposure is the early detection of morbidity clusters, apart from background morbidity, after a relatively short incubation period. For this reason, it is important that clinicians be familiar with the clinical manifestations of toxins and the appropriate methods of management and countermeasures.

  2. Probabilistic consequence study of residual radiological effects from a hypothetical ten-ton inadvertent nuclear yield. Weapons Safety Program

    1994-01-01

    In this paper we study the potential radiological consequences of a strategic bomber accident, in which one of the assumed on-board nuclear weapons explodes with an arbitrarily chosen 10-ton nuclear yield. The frequency of such an occurrence is infinitesimal. The safety design features in today s nuclear weapons' systems essentially forbid its occurrence. We have a chosen a military base which has the feature of being a representative combination of urban and rural populations. The assumed ''crash site'' is near the northwest comer of the military base, close to civilian housing located just across the street from the base. A worst case wind would be from the ESE (east south east). This would cause fission debris to be dispersed toward the largest population centers and, thus, would lead to the largest Pu ''collective'' doses (i.e., a dose integrated over time and summed over individuals). Also, if an ESE wind were blowing at accident time, some people in nearby housing could receive lethal gamma-ray doses from fallout before evacuation could occur. It is assumed only one weapon undergoes nuclear yield; the other on-board weapons would HE detonate and the Pu would be aerosolized and lofted. We assume an activity-size distribution and lofting similar to those used to predict fallout measured at NTS. The main thrust of our study is to provide estimates of probabilistic radiological risks to the population local to a strategic bomber crash site. The studied radiological consequences are: cloud-passage doses from Pu inhalation; doses from groundshine due to gamma-producing radionuclides; and areal contamination from Pu and the long-lived fission products Cs-137 and Sr-90

    The article gives an overview on worldwide efforts to eliminate chemical weapons and facilities for their production in the context of the implementation of the 1997 Chemical Weapons Convention (CWC). It highlights the objectives of the Organisation for the Prohibition of Chemical Weapons (OPCW), the international agency set up in The Hague to implement the CWC, and provides an overview of the present status of implementation of the CWC requirements with respect to chemical weapons (CW) destruction under strict international verification. It addresses new requirements that result from an increased threat that terrorists might attempt to acquire or manufacture CW or related materials. The article provides an overview of risks associated with CW and their elimination, from storage or recovery to destruction. It differentiates between CW in stockpile and old/abandoned CW, and gives an overview on the factors and key processes that risk assessment, management, and communication need to address. This discussion is set in the overall context of the CWC that requires the completion of the destruction of all declared CW stockpiles by 2012 at the latest.

    2002-04-01

    This thesis concerns a nuclear accident that occurred in the Thule (Pituffik) area, NW Greenland in 1968, called the Thule accident.Results are based on different analytical techniques, i.e. gamma spectrometry, alpha spectrometry, ICP-MS, SEM with EDX and different sediment models, i.e. (CRS, CIC). The scope of the thesis is the study of hot particles. Studies on these have shown several interesting features, e.g. that they carry most of the activity dispersed from the accident, moreover, they have been very useful in the determination of the source term for the Thule accident debris. Paper I, is an overview of the results from the Thule-97 expedition. This paper concerns the marine environment, i.e. water, sediment and benthic animals in the Bylot Sound. The main conclusions are; that plutonium is not transported from the contaminated sediments into the surface water in this shelf sea, the debris has been efficiently buried in the sediment to great depth as a result of biological activity and transfer of plutonium to benthic biota is low. Paper II, concludes that the resuspension of accident debris on land has been limited and indications were, that americium has a faster transport mechanism from the catchment area to lakes than plutonium and radio lead. Paper III, is a method description of inventory calculation techniques in sediment with heterogeneous activity concentration, i.e. hot particles are present in the samples. It is concluded that earlier inventory estimates have been under estimated and that the new inventory is about 3.8 kg (10 TBq) of {sup 239,240}Pu. Paper IV, describes hot particle separation/identification techniques using real-time digital image systems. These techniques are much faster than conventionally used autoradiography and give the results in real time. Paper V, is a study of single isolated hot particles. The most interesting result is that the fission material in the weapons involved in the accident mostly consisted of {sup 235}U

    The Laser-Ultrasonic technique uses laser energy to generate ultrasound waves in various solids. In normal conditions, this technique is used to inspect large structures without destruction, but in military use, we hope get this destruction. Nociceptors in Human skin can feel cold, heat, mechanical and other stimuli, when the stimulus exceeds a certain threshold will produce pain. Based on this principle, a laser induced pain weapon may be made. The generated ultrasound wave form is affected by features of laser pulse. The results obtained from the finite element model of laser generated ultrasound are presented in terms of temperature and displacement. At first step, the transient temperature field can be precisely calculated by using the finite element method. Then, laser generated surface acoustic wave forms are calculated by coupling the temperature distribution. Displacement is used to represent the mechanical action of skin caused by laser ultrasound. Results from numerical simulation are compared with other references; the accuracy of the method is proved accordingly. The results of simulation in the given conditions demonstrate that the stresses generated by pulse laser in human skin model were about -8 and +4 MPa. According to the results of simulation, the max and min stress are both emerged in the range of 0 600 um, that is exactly the location of myelinated Aδ and unmyelinated C nociceptor. The value of stress is can be adjusted by chose suitable parameters of laser. The study provides a possibility for developing a new non-lethal weapon to control riots or crowd.

    2007-01-01

    The optical properties of the F A1 :Ag + color centers and CN interactions at the flat, edge and corner surfaces of LiI (0 0 1) were investigated by using quantum mechanical configuration interaction singles (CIS) and density functional theory (DFT) ab initio methods. Clusters of variable sizes were embedded in the simulated Coulomb fields that closely approximate the Madelung fields of the host surfaces, and the nearest-neighbor ions to the defect site were allowed to relax to equilibrium in order to calculate the optical properties. The sensitivity of the calculated transition energies (Stokes shifts) of F A1 :Ag + centers as well as related optical properties such as optical-optical conversion efficiency, relaxed excited states of the defect-containing surface, orientational destruction of the point defect, recording sensitivity, and the Glasner-Tompkins empirical rule, to the coordination number of the surface ion and artificial polarization were examined. The dependance of the adsorption energies of CN at LiI (0 0 1) surface, the coadsorption of CN, and the charge transfer reactions between CN and the paramagnetic iodine vacancy on the coordination number and artificial polarization effects were also clarified

    This dissertation provides a history of Canadian ideas about nuclear weapons from the late 1950s until the end of the Trudeau era in 1984. Throughout this period, Canadians reacted to the insecurity they felt in the world around them by expressing many conflicting, often irreconcilable views about a range of nuclear weapon issues, including Canada's acquisition of nuclear warheads in 1963, the U.S. ABM program in the 1960s and early 1970s, the role of Canadian nuclear technology in the development of India's first nuclear explosion, and the Trudeau government's decision to allow the U.S. military to test cruise missiles in northern Canada The dissertation concludes with an examination of the emergence of a broadly-based, increasingly mainstream and influential anti-nuclear movement in the early 1980s, the clearest manifestation of the insecurity Canadians experienced at the time. .The nuclear debates examined in this dissertation reveal that Canadians were divided over nuclear weapons, nuclear strategy, the arms race, proliferation, and arms control and disarmament. In particular, they came to fundamentally different conclusions about how Canada's nuclear weapon policies, and its support for the nuclear policies of its alliances, would contribute to international stability and order. Some believed that their security rested on the maintenance of a strong Western nuclear deterrent and supported Canada contributing to its credibility; others believed that the constant modernisation of nuclear arsenals fuelled by the superpower arms race posed a serious threat to their security. This conceptual dilemma-the security through nuclear strength argument versus the fear that the quest for security through quantitative and qualitative improvements of nuclear stockpiles increased the likelihood of nuclear war-left Canadians divided over the value and utility of nuclear weapons and the strategies developed around them. At the same time, Canadians

    This thesis deals with the possible employment of nuclear weapons in the ongoing confrontation between India and Pakistan. After reviewing the nuclear capabilities of both Indian and Pakistan and assessing their possible delivery systems, this dissertation explores the emerging picture regarding the Indian and Pakistani nuclear doctrines. It is argued that, after exploring the current structure of the armed forces in both countries and after analyzing the theatres of operations, it is highly unlikely that either country seeks to employ nuclear weapons in a tactical, battlefield role. It is also argued that neither India or Pakistan is making an effort to evolve a nuclear war-fighting doctrine. Moreover, it is shown that nuclear weapons have simply led to a re-thinking of military tactics on the part of India so as to minimize the chance of a nuclear strike by limiting the aims and objectives of any Indian military action. In stark contrast, it is shown that South Asian cities present far more lucrative targets for nuclear strikes. As a result of this and the geographic and tactical limitations of South Asian battlefields, it is argued that both India and Pakistan have based their fledgling nuclear strategies around a 'city-busting' concept. The existing command and control systems in both countries are examined and found to be adequate if both countries adopt a strict 'second-strike' approach to the employment of nuclear weapons. It is further argued that nuclear weapons, while limiting the scale of any future India-Pakistan war, will not play a major role in preventing a conflict between the two countries. Rather, the basic operational parity that exists between the two countries in terms of their conventional forces is responsible for preventing the outbreak of war. The thesis also briefly explores the rationale behind the acquisition of nuclear weapons in both countries and on their basic security perceptions. The issue of confidence building measures and the

    Torch Technologies Inc., is actively involved in chemical sensor networking and data fusion via multi-year efforts with Dugway Proving Ground (DPG) and the Defense Threat Reduction Agency (DTRA). The objective of these efforts is to develop innovative concepts and advanced algorithms that enhance our national Chemical Warfare (CW) test and warning capabilities via the fusion of traditional and non-traditional CW sensor data. Under Phase I, II, and III Small Business Innovative Research (SBIR) contracts with DPG, Torch developed the Advanced Chemical Release Evaluation System (ACRES) software to support non real-time CW sensor data fusion. Under Phase I and II SBIRs with DTRA in conjunction with the Edgewood Chemical Biological Center (ECBC), Torch is using the DPG ACRES CW sensor data fuser as a framework from which to develop the Cloud state Estimation in a Networked Sensor Environment (CENSE) data fusion system. Torch is currently developing CENSE to implement and test innovative real-time sensor network based data fusion concepts using CW and non-CW ancillary sensor data to improve CW warning and detection in tactical scenarios.

    1987-11-01

    Judging from its name alone, the Atomic Energy Control Board would seem a logical place to get information on nuclear weapons. If we are involved in the control of atomic energy, we must know something about its military uses. In actual fact, however, our regulatory activities are restricted to the development and use of nuclear energy for peaceful purposes, and our safeguards - an international audit system to discourage the diversion of nuclear materials and equipment from peaceful applications to the production of explosive devices. Not being the best source of information on the subject of weapons, we have prepared this fact sheet to assist your research. Simply look for the topic heading that interests you, to find out where to go for more information.

    During the hardest times of the Cold War, like in October 1962 with the Cuba crisis, the World lived in the fear of a nuclear confrontation between the USA and the USSR. If this time seems far away now, the risks of a nuclear conflict are probably greater today because no serious progress has bee done during the last ten years and because, from now on, nine, and maybe ten states possess nuclear weapons. In April 2009, US President Barack Obama, gave a talk in Prague (Czech Republic) in which he stressed again on the enormous risks that this situation was running on humanity and urged the world to get rid of nuclear weapons. The aim of this book is to present the main steps of this process, which started in the 1960's, and the arguments which justify its necessity. (J.S.)

    Three new adhesives of the polyurethane type have been developed to meet the requirements for the current phase 3 nuclear weapons. They are designated Halthanes to avoid confusion with Adiprenes. Two of these adhesives are made from LLL-developed MDI-terminated prepolymers cured with a blend of polyols. The third is made from an LLL-developed prepolymer terminated with Hylene W and cured with aromatic diamines. All of the adhesives have low moduli over a wide temperature range, bond rapidly and well to most substrates, and are compatible with weapons components. This report updates information reported in Chemistry Department Technical Notes Nos. 75-23 and 75-24. Characterization and compatibility studied are continuing

    Full Text Available This paper aims at explaining the lessons learned from the chemical attacks that took place in 2013 in the Syrian military conflict, especially the sarin attacks on the Ghouta area of Damascus on August 21. Despite the limitations the UN Mission found while investigating the use of chemical weapons (CW in Syria, some interesting conclusions for the scientific and medical community can be obtained from its reports. These include the advantages of the Chemical Weapons Convention procedure for the investigation of alleged CW use, when compared with the United Nations mechanism for similar investigations, the difficulties of differential diagnosis based only on clinical signs and symptoms and the impact of secondary contamination when responding to a CW attack.

    2016-03-01

    Full Text Available This article details the terrorist activities of the Japanese cult, Aum Shinrikyo, from the perspective of its complex engineering efforts aimed at producing nuclear and chemical weapons. The experience of this millenarian organization illustrates that even violent non-state actors with considerable wealth and resources at their disposal face numerous obstacles to realizing their destructive aspirations. Specifically, Aum’s attempts at complex engineering were stymied by a combination of unchecked fantastical thinking, self-imposed ideological constraints, and a capricious leadership. The chapter highlights each of these mechanisms, as well as the specific ways in which they constrained the decision-making process and the implementation of the complex engineering tasks associated with their unconventional weapons development.

    2012-07-01

    Full Text Available In martial tradition, spears and lances have always played a very important role as main weapons on the battlefield, as exemplified through Iranian military history. Its reach and cheap production were important factors for establishing formations of soldiers equipped with spears and lances. Additionally, the combat techniques of spears and lances were relatively easy and one could learn the techniques of spearfighting and lancefighting much easier than other weapons, such as swords. The first part of the article describes some types of spears and lances that were used in the Islamic period of Iran. Then the method of carrying a spear/lance is analyzed and additionally some offensive techniques, feinting techniques, attacking techniques to the animal carrying the opponent, and defensive techniques using spears/lances are described as documented by Persian manuscripts.

    1995-01-01

    Beyond the satisfaction of witnessing the end of the nuclear arms race, the availability of large quantities of plutonium from the dismantlement of nuclear weapons in Russia and the US can be perceived as a challenge and an opportunity. A challenge because poor management of this material would maintain a problematic situation in terms of proliferation; an opportunity because such plutonium represents a high value energy source that the civilian industry is capable of using efficiently, actually turning it from swords to plowshares. The object of this paper is to describe the main characteristics of the use of weapons plutonium in the civilian cycle to produce electricity through the use of mixed uranium-plutonium oxide (MOX), or moxification. A comparison with the main alternate solution--plutonium vitrification--is offered, in particular with regard to industrial availability, energy resource management, economy, environment and proliferation

    2006-01-01

    Full Text Available As terrorists attacks increase in frequency, hospital disaster plans need to be scrutinized to ensure that they take into account issues unique to weapons of mass destruction. This paper reports a review of the literature addressing hospital experiences with such incidents and the planning lessons thus learned. Construction of hospital disaster plans is examined as an ongoing process guided by the disaster planning committee. Hospitals are conceived as one of the components of a larger community disaster planning efforts, with specific attention devoted to defining important linkages among response organizations. This includes the public health authorities, political authorities, prehospital care agencies, and emergency management agencies. A review is completed of six special elements of weapons of mass destruction incidents that should be addressed in hospital disaster plans: incident command, hospital security, patient surge, decontamination, mental health consequences, and communications. The paper closes with a discussion of the importance of training and exercises in maintaining and improving the disaster plan.

    Ewing, R.C.; Lutze, W.; Weber, W.J.

    1995-05-01

    At present, there are three seriously considered options for the disposition of excess weapons plutonium: (i) incorporation, partial burn-up and direct disposal of MOX-fuel; (ii) vitrification with defense waste and disposal as glass ''logs''; (iii) deep borehole disposal (National Academy of Sciences Report, 1994). The first two options provide a safeguard due to the high activity of fission products in the irradiated fuel and the defense waste. The latter option has only been examined in a preliminary manner, and the exact form of the plutonium has not been identified. In this paper, we review the potential for the immobilization of plutonium in highly durable crystalline ceramics apatite, pyrochlore, monazite and zircon. Based on available data, we propose zircon as the preferred crystalline ceramic for the permanent disposition of excess weapons plutonium

    2008-11-01

    This report addresses the development of a nuclear infrastructure in Iran, and assessments are made on the near-term potential this infrastructure might yield of either nuclear power or nuclear arms production. The most significant facilities are treated in a more elaborate fashion, as these are assumed to have key roles in either a true civilian programme, or in the prospect of weapons-grade fissile material production. The future potential capacity for the latter is calculated under certain presumptions, both in the case that Iran focuses its efforts on uranium-based nuclear weapons, and in the case that it should choose the plutonium path to nuclear weapons. All the conclusions and findings in this report are based on technological considerations. This means that social or political assessments have not prevailed, rather the picture of Iran's nuclear programme is drawn through descriptions and assessments of facilities and systems, and their role in the bigger context. Definite conclusions have not been made as to whether Iran's nuclear programme currently is aimed towards nuclear arms or nuclear power. The secrecy surrounding some of the most prominent nuclear sites together with more or less credible allegations of purely weapons-related activities in the past, make it hard not to conclude that Iran until the disclosures in 2002 made as great an effort as it could on its way on developing nuclear weapons covertly. The scope of today's nuclear programme seems, on the other hand, most likely to be in part to help relieve the ever-increasing need for energy, although considerable deficits to this strategy are identified, at the same time as the Iranian people are united in a giant, high-prestige project in defiance of massive international pressure. Adding to this is a much-feared ability to rapidly being able to redirect their nuclear efforts, and develop nuclear arms in perhaps as little as one year. This so-called break-out scenario, where Iran presumably

    2010-01-01

    The U.S. Department of energy has decided to dispose of a portion of the nation's surplus weapons-grade plutonium by reconstituting it into mixed oxide (MOX) fuel and irradiating the fuel in commercial power reactors. Four lead test assemblies (LTAs) were manufactured with weapons-grade mixed oxide (WG-MOX) fuel and irradiated in the Catawba Nuclear Station Unit 1, to a maximum fuel rod burnup of ∼47.3 GWd/MTHM. As part of the fuel qualification process, five rods with varying burnups and initial plutonium contents were selected from one assembly and shipped to the Oak Ridge National Laboratory (ORNL) for hot cell examination. ORNL has provided analytical support for the post-irradiation examination (PIE) of these rods via extensive fuel performance modeling which has aided in instrument settings and PIE data interpretation. The results of these fuel performance simulations are compared in this paper with available PIE data.

    The fuel cycle industry in Russia has necessary basis and experience to begin solving problems of ensuring safe utilisation of weapons plutonium. Russian concept of plutonium management (both civil and military) is based on the fuel cycle closing in the nuclear power industry to increase the efficiency of the fuel use and decrease the activity of the long lived waste. Short term program of plutonium management in Russia includes safe and reliable storage of weapons and separated civil plutonium until they are used in reactors. Further studies are needed concerning optimal use of MOX fuel in fast BN reactors as well as in WWER type reactors having in mind non-proliferation aspects, nuclear radiation safety, economics and ecology

  7. A simple method for rapidly processing HEU from weapons returns

    1994-01-01

    A method based on the use of a high temperature fluidized bed for rapidly oxidizing, homogenizing and down-blending Highly Enriched Uranium (HEU) from dismantled nuclear weapons is presented. This technology directly addresses many of the most important issues that inhibit progress in international commerce in HEU; viz., transaction verification, materials accountability, transportation and environmental safety. The equipment used to carry out the oxidation and blending is simple, inexpensive and highly portable. Mobile facilities to be used for point-of-sale blending and analysis of the product material are presented along with a phased implementation plan that addresses the conversion of HEU derived from domestic weapons and related waste streams as well as material from possible foreign sources such as South Africa or the former Soviet Union.

    In this paper author deals with the plutonium produced in power reactors and with their using. Excess plutonium, mineralized in a ceramic matrix and incised in HLW glass, is a less attractive target for terrorist groups than either aged, irradiated weapons grade MOX fuel, or aged, U oxide spent fuel. This is especially true after the Russian and United States' Pu Disposition Programs have been completed, until the material (spent MOX fuel or the immobilized form) is stored in a sealed, repository.

  12. Nuclear weapons proliferation as a world order problem

    International Nuclear Information System (INIS)

    Falk, R.

    1977-01-01

    World-order concerns have intensified recently in light of mounting evidence that a weapons capability will soon be within easy reach of more and more governments and of certain nongovernmental groupings as well. One reliable source estimates that by 1985 as many as fifty countries could ''produce enough plutonium each year for at least several dozen nuclear explosives.'' In an even more immediate sense, ''economic competition among nuclear suppliers today could soon lead to a world in which twenty or more nations are but a few months from a nuclear weapons force.'' Three developments have created this ''world order'' sense of concern: (1) increased pace of civilian nuclear power deployment globally as a consequence of rising oil prices, unreliability of oil supplies, and reality of dwindling oil reserves in any case; (2) actuality of India's nuclear explosion in May 1974 which demonstrated vividly how any state that pursues a ''civilian'' program can also develop its own weapons capability; and (3) the intensification of competition for international nuclear sales which makes it increasingly evident that nonproliferation goals are no longer compatible with the pursuit of national commercial advantage; essentially, this reality has emerged from a break in the American monopoly over civilian nuclear technology and the willingness of French and German suppliers to provide all elements of the nuclear fuel cycle, including enrichment and reprocessing facilities,to any nation that feels it can afford to buy them; the German-Brazilian deal (worth at least $4 billion) has proven to be the equivalent in the commercial realm of India's ''peaceful'' nuclear explosion. Such developments disclose the alarming prospect that easier access to nuclear technology will make it relatively simple and thus more likely for a beleaguered government or a desperate political actor of any sort to acquire and possibly use nuclear weapons

    US scientists argue for funding to support basic research which would make the decommissioning of one of the world's nuclear stockpiles cheaper and more effective. This runs contrary to current popular and political thought, from citizens' groups and state governments, that the stockpile should be dismantled immediately and publicly due to their suspicion of scientists and fear that stockpiled weapons could still be used. This article examines the debate between the two opposing views. (UK)

    Furukawa, K.

    2009-01-01

    The Aum Shinrikyo, an obscure cult religious group, attacked the Tokyo subways employing sarin gas in March 1995, which was viewed as a mark of a new era in terrorism. The Aum Shinrikyo remains the one empirical example of a religiously motivated cult with an affluent amount of financial and human resources and motivations to use unconventional weapons. The Aum Shinrikyo's leaders included the scientific elite of a young generation as well as former Yakuza members who had close ties with organized crime networks. Aum succeeded in establishing an extensive network to procure weapons, material, and drug, primarily in Russia but also other countries including the United States and even North Korea. Despite the fact that the law enforcement authority had already obtained various pieces of information that reasonably indicated that Aum was producing sarin by late 1994, the law enforcement authority became too cautious to advance its investigation to arrest Aum members until it was too late. Japan's experience with the Aum Shinrikyo's threats provides valuable insights for democratic governments seeking to thwart the deadly plans of religiously motivated non-state actors. It reveals the tremendous difficulties for a democratic society to confront the terrorists who were willing to pursue their deadly 'divine' objectives, especially when the society had no experience to encounter such a threat. This presentation will explain the chemical and biological weapon programs of the Aum Shinrikyo, especially focusing on the following elements: Intention and capability of the Aum Shinrikyo; Weapon systems and mode of attacks, including their target selections; The lessons learned from this case for the prevention and crisis/consequence management n the event of CBW terrorism.

    2009-02-01

    Full Text Available Abstract In December 2008, the US Commission on the Prevention of Weapons of Mass Destruction Proliferation and Terrorism, released a report, World At Risk. The Report points to the fact that, not only is the use of a weapon of mass destruction in a terrorist attack before the end of 2013, more likely than not, but also to the fact that terrorists are more likely to be able to obtain and use biological weapons than nuclear. This paper examines the recommendations of the report in the context of the historic and geopolitical changes, in particular globalization. The authors highlight the "dual-use" dilemma, as described in the report, as the paradoxical use of technology developed for the benefit of mankind being used for sinister purposes. The mitigation of such a threat lies in broad stakeholder involvement and cooperation, including non-state actors, governments and the bio-tech industry itself. The importance of vigilance measures within the life science community is emphasized and, the authors propose, could include a web-based didactic course in bioterrorism and weapons of mass destruction identification. The site could outline safety protocols, have detailed disaster management tutorials, and could be specifically tailored for different subsets of industry and health professionals. The paper concludes with an endorsement of a multi-pronged approach including strong international guidelines and intelligence cooperation and preparatory measures such as the wide-spread use of detection systems as well as diagnostic decision support systems for bioterrorism detection at the local level.

  3. Disposal of fissionable material from dismantled nuclear weapons

    International Nuclear Information System (INIS)

    Taylor, J.J.

    1991-01-01

    The reduction in tensions between the United States and the Soviet Union has improved the prospects for nuclear disarmament, making it more likely that significant numbers of nuclear warheads will be dismantled by the United States and USSR in the foreseeable future. Thus, the question becomes more urgent as to the disposition of the weapons materials, highly enriched uranium and plutonium. It is timely, therefore, to develop specific plans for such disposal. The overall process for disposal of weapons materials by the burnup option involves the following steps: (1) removing the weapons material from the warheads, (2) converting the material to a fuel form suitable for power reactors, (3) burning it up as a power reactor fuel, and (4) removing the spent fuel and placing it in a permanent repository. This paper examines these four steps with the purpose of answering the following questions. What facilities would be appropriate for the disposal process? Do they need to be dedicated facilities, or could industrial facilities be used? What is the present projection of the economics of the burnup process, both the capital investment and the operating costs? How does one assure that fissionable materials will not be diverted to military use during the disposal process? Is the spent fuel remaining from the burnup process proliferation resistant? Would the disposal of spent fuel add an additional burden to the spent fuel permanent repository? The suggested answers are those of the author and do not represent a position by the Electric Power Research Institute

    Full Text Available The following article presents the development of the bow and arrow, and its important role in the history of Iran. The bow always played an important role not only on the battlefield, but also in hunting. It was also considered as a sacred weapon and additionally a royal symbol. Bow and arrow were considered as a superior weapon in comparison with other types of weapons because one could fight with them at a safer distance as one offered by swords, maces and axes. The first part of the article presents a short history of the bow in Iran. Based on historical Persian manuscripts, the next part explains the structure of the composite bow and the materials used for making it. The third part describes some types of bows based on the material, place of production, the usage, and bow type based on the length of the bow and the arrows. The following part talks about different types of arrows based on morphology of arrowheads, the type of plume/feather, the material of the shaft, the material of the arrowhead, the length of arrows, the target of arrows, the place of production of arrowheads and terms for describing its different features of an arrowhead. Then, the article talks about different types of thumb rings, bowstrings, quivers and bow cases and arrow guides for shooting short arrows. The next part discusses different principles of archery as explained in Persian manuscripts. Finally the article describes different archery targets.

    2014-07-01

    The radical religious group Aum Shinrikyo was founded in Japan in the 1980s and grew rapidly in the 1990s. Aum members perpetrated a mass murder in Matsumoto City in 1994, where they used sarin as a chemical weapon to poison approximately 500 civilians. On March 20, 1995, Aum deployed sarin in an even larger terrorist attack on the Tokyo Subway System, which poisoned some 6,000 people. After the Tokyo Subway attack, the Japanese Police arrested the sect's senior members. From 2005 through 2011, 13 of these senior members were sentenced to death. In this article, aspects of Aum's chemical and biological terrorism are reviewed. Sarin production efforts by the sect are described, including how the degradation product of sarin in soil, methylphosphonic acid, enabled the detection of sarin production sites. Also, Aum's chemical-warfare agents other than sarin are described, as are its biological weapons. The author was permitted by the Japanese government to interview Dr. Tomomasa Nakagawa, one of the senior members of Aum Shinrikyo. From Dr. Nakagawa the author obtained valuable inside information about Aum's chemical and biological weapons programs. Copyright © 2014 Central Police University.

    The Convention on the Prohibition on the Development, Production, Stockpiling and Use of Chemical Weapons and on their Destruction, opened for signature, January 13, 1993, in Paris, France (CWC), is an unprecedented multilateral effort to eradicate an entire category of weapons of mass destruction and assure their continued absence through international verification. The CWC has been signed by over 150 nations, and is expected to enter into force in 1995. With its far-reaching system to verify compliance, the CWC presages a new foundation for international security based neither on fear nor on trust, but on the rule of law. A central feature of the CWC is that it requires each State Party to take implementing measures to make the Convention operative. The CWC goes beyond all prior arms control treaties in this regard. For this approach to succeed, and to inspire the eradication of other categories of mass destruction weaponry, coordination and planning are vital to harmonize CWC national implementation among States Parties. This Manual for National Implementation of the Chemical Weapons Convention is designed to assist States Parties, duly taking into account the distinctive aspects of their legal systems, in maximizing CWC enforcement consistent with their national legal obligations.

    Jaeger, C.D.

    1994-01-01

    Sandia National Laboratories was a member of the Weapons Complex Reconfiguration (WCR) Safeguards and Security (S ampersand S) team providing assistance to the Department of Energy's (DOE) Office of Weapons Complex Reconfiguration. The physical security systems in the new and upgraded facilities being considered for the WCR had to meet DOE orders and other requirements set forth in the WCR Programmatic Design Criteria (PDC), incorporate the latest physical security technologies using proven state-of-the-art systems and meet fundamental security principles. The outcome was to avoid costly retrofits and provide effective and comprehensive protection against current and projected threats with minimal impact on operations, costs and schedule. Physical security requirements for WCR facilities include: (1) reducing S ampersand S life-cycle costs, (2) where feasible automating S ampersand S functions to minimize operational costs, access to critical assets and exposure of people to hazardous environments, (3) increasing the amount of delay to outsider adversary attack, (4) compartmentalizing the facility to minimize the number of personnel requiring access to critical areas and (5) having reliable and maintainable systems. To be most effective against threats physical security must be integrated with facility operations, safety and other S ampersand S activities, such as material control and accountability, nuclear measurements and computer and information security. This paper will discuss the S ampersand S issues, requirements, technology opportunities and needs. Physical security technologies and systems considered in the design effort of the Weapons Complex Reconfiguration facilities will be reviewed

    Everyone knows about the reported recovery of a crashed alien spaceship near Roswell, New Mexico in July 1947. However, most people are unaware that, at the time of the incident, Roswell Army Airfield was home to the world's only atomic bomber squadron, the 509th Bomb Group. Was this merely a coincidence? During the Cold War, the United States and the Soviet Union built thousands of the far more destructive hydrogen bombs, some of them a thousand times as destructive as the first atomic bombs dropped on Japan. If the nuclear standoff between the superpowers had erupted into World War III, human civilization - and perhaps the very survival of our species - would have been at risk. Did this ominous state of affairs come to the attention of outside observers? Was there a connection between the atomic bomber squadron based at Roswell and the reported crash of a UFO nearby? Did those who pilot the UFOs monitor the superpowers' nuclear arms race during the dangerous Cold War era? Do they scrutinize American and Russian weapons sites even now? UFOs and Nukes provides the startling and sometimes shocking answers to these questions. Veteran researcher Robert Hastings has investigated nuclear weapons-related UFO incidents for more than three decades and has interviewed more than 120 ex-US Air Force personnel, from former Airmen to retired Colonels, who witnessed extraordinary UFO encounters at nuclear weapons sites. Their amazing stories are presented here.

    It is pointed out that the long-range antiship standoff missile is emerging as the foremost threat on the seas. Delivered by high speed bombers, surface ships, and submarines, a missile attack can be mounted against selected targets from any point on the compass. An investigation is conducted regarding the configuration of a system which could most efficiently identify and destroy standoff threats before they launch their weapons. It is found that by using ships for carrying and launching missiles, and employing aircraft with a powerful radar only for search and missile directing operations, aircraft cost and weight can be greatly reduced. The employment of V/STOL aircraft in preference to other types of aircraft makes it possible to use ships of smaller size for carrying the aircraft. However, in order to obtain an all-weather operational capability for the system, ships are selected which are still big enough to display the required stability in heavy seas.

    2018-03-01

    We present a multiscale study examining the impact of a regional exchange of nuclear weapons on global climate. Our models investigate multiple phases of the effects of nuclear weapons usage, including growth and rise of the nuclear fireball, ignition and spread of the induced firestorm, and comprehensive Earth system modeling of the oceans, land, ice, and atmosphere. This study follows from the scenario originally envisioned by Robock, Oman, Stenchikov, et al. (2007, https://doi.org/10.5194/acp-7-2003-2007), based on the analysis of Toon et al. (2007, https://doi.org/10.5194/acp-7-1973-2007), which assumes a regional exchange between India and Pakistan of fifty 15 kt weapons detonated by each side. We expand this scenario by modeling the processes that lead to production of black carbon, in order to refine the black carbon forcing estimates of these previous studies. When the Earth system model is initiated with 5 × 109 kg of black carbon in the upper troposphere (approximately from 9 to 13 km), the impact on climate variables such as global temperature and precipitation in our simulations is similar to that predicted by previously published work. However, while our thorough simulations of the firestorm produce about 3.7 × 109 kg of black carbon, we find that the vast majority of the black carbon never reaches an altitude above weather systems (approximately 12 km). Therefore, our Earth system model simulations conducted with model-informed atmospheric distributions of black carbon produce significantly lower global climatic impacts than assessed in prior studies, as the carbon at lower altitudes is more quickly removed from the atmosphere. In addition, our model ensembles indicate that statistically significant effects on global surface temperatures are limited to the first 5 years and are much smaller in magnitude than those shown in earlier works. None of the simulations produced a nuclear winter effect. We find that the effects on global surface temperatures

    Directory of Open Access Journals (Sweden)

    Jasjit Singh

    2012-10-01

    Full Text Available The primary objections raised against total elimination of nuclear weapons are built around a few arguments mostly of non-technical nature.Nuclear weapons and the strategies for their use have resulted in the establishment of a vicious circle within which the international community is trapped.The argument that the world will be unsafe without nuclear weapons is only meant to further the narrow self-interest of the nuclear weapon states and their allies.The World Court’s far-reaching 1996 advisory opinion concluded that almost any use or threat of use of nuclear weapons would violate international humanitarian law and law applicable in armed conflict, undermining most claims of nuclear weapon states regarding the legitimacy of possession, use or threat of use of nuclear weapons. The next logical step would be an initiative for a nuclear convention banning the use and threat of use of nuclear weapons in Asia and the adjoining oceans. But as long as the dominant elites in society and the nation-state believe in the utility of nuclear weapons for national security or as the currency of power, abolition of nuclear weapons will remain a mirage.

    We investigated the prevalence of juvenile weapon carrying and psychosocial and personality-related risk factors for carrying different types of weapons in a nationally representative, population-based sample of Finnish adolescents. Specifically, we aimed to investigate psychopathic-like personality features as a risk factor for weapon carrying. The participants were 15-16-year-old adolescents from the Finnish self-report delinquency study (n = 4855). Four different groups were formed based on self-reported weapon carrying: no weapon carrying, carrying knife, gun or other weapon. The associations between psychosocial factors, psychopathic-like features and weapon carrying were examined with multinomial logistic regression analysis. 9% of the participants had carried a weapon in the past 12 months. Adolescents with a history of delinquency, victimization and antisocial friends were more likely to carry weapons in general; however, delinquency and victimization were most strongly related to gun carrying, while perceived peer delinquency (antisocial friends) was most strongly related to carrying a knife. Better academic performance was associated with a reduced likelihood of carrying a gun and knife, while feeling secure correlated with a reduced likelihood of gun carrying only. Psychopathic-like features were related to a higher likelihood of weapon carrying, even after adjusting for other risk factors. The findings of the study suggest that adolescents carrying a weapon have a large cluster of problems in their lives, which may vary based on the type of weapon carried. Furthermore, psychopathic-like features strongly relate to a higher risk of carrying a weapon.

    Full text: Considerations revolving around physical protection of nuclear material are quite commonly and naturally focused on protecting weapons-grade plutonium (WGPu) and highly enriched uranium (HEU) from theft and diversion. These two materials are the center of attention because of their well-known (and demonstrated) potential for use in first-generation nuclear explosive devices of which potential terrorists are widely thought to be capable. They are also the center of attention because of retirements of these materials from military use as the Russian Federation and the United States reduce the number of nuclear weapons in their arsenals. Three other materials - an 'overlooked trio' - must also be borne in mind within this context: (1) reactor-grade plutonium (RGPu); (2) neptunium-237 (Np-237); and (3) tritium (H-3). Although there are still some authorities who either contend that RGPu cannot be used in a nuclear explosive or that there are (for a terrorist) insurmountable difficulties in doing so, the knowledgeable scientific and technical community, recognizes the potential utility of RGPu for hypothetical terrorist nuclear devices. A much smaller community of experts recognizes the usefulness of Np-237 for nuclear devices, but Np-237 is as straight-forwardly and easily usable as HEU and similarly abundant (but not often in separated form). Tritium can be used (with a modest increase in design sophistication) in a conventional first-generation nuclear device with any of the weapons-usable materials (WGPu, HEU, RGPu or Np-237) to increase the yield and/or increase the reliability of a non-fizzle yield. Given the presence of RGPu and Np-237 in abundant quantities in spent commercial reactor fuel, widely available knowledge of how to separate these materials, and a world-wide total of more than 400 nuclear power plants, spent reactor fuel also requires stringent controls. This is especially true of old spent fuel which has far less radiation dose

    Lawrence Livermore and Los Alamos National Laboratories have developed a common framework and key elements of a national certification methodology called Quantification of Margins and Uncertainties (QMU). A spectrum from senior managers to weapons designers has been engaged in this activity at the two laboratories for on the order of a year to codify this methodology in an overarching and integrated paper. Following is the certification paper that has evolved. In the process of writing this paper, an important outcome has been the realization that a joint Livermore/Los Alamos workshop on QMU, focusing on clearly identifying and quantifying differences between approaches between the two labs plus developing an even stronger technical foundation on methodology, will be valuable. Later in FY03, such a joint laboratory workshop will be held. One of the outcomes of this workshop will be a new version of this certification paper. A comprehensive approach to certification must include specification of problem scope, development of system baseline models, formulation of standards of performance assessment, and effective procedures for peer review and documentation. This document concentrates on the assessment and peer review aspects of the problem. In addressing these points, a central role is played by a 'watch list' for weapons derived from credible failure modes and performance gate analyses. The watch list must reflect our best assessment of factors that are critical to weapons performance. High fidelity experiments and calculations as well as full exploitation of archival test data are essential to this process. Peer review, advisory groups and red teams play an important role in confirming the validity of the watch list. The framework for certification developed by the Laboratories has many basic features in common, but some significant differences in the detailed technical implementation of the overall methodology remain. Joint certification workshops held in June

    Chemical weapons dumped into the ocean for disposal in the twentieth century pose a continuing environmental and human health risk. In this review we discuss locations, quantity, and types of sea-dumped chemical weapons, related environmental concerns, and human encounters with sea-dumped chemical weapons. We utilized the Ovid (http://ovidsp.tx.ovid.com) and PubMed (http://www.pubmed.org) search engines to perform MEDLINE searches for the terms 'sea-dumped chemical weapons', 'chemical warfare agents', and 'chemical munitions'. The searches returned 5863 articles. Irrelevant and non-English articles were excluded. A review of the references for these articles yielded additional relevant sources, with a total of 64 peer-reviewed articles cited in this paper. History and geography of chemical weapons dumping at sea: Hundreds of thousands of tons of chemical munitions were disposed off at sea following World War II. European, Russian, Japanese, and United States coasts are the areas most affected worldwide. Several areas in the Baltic and North Seas suffered concentrated large levels of dumping, and these appear to be the world's most studied chemical warfare agent marine dumping areas. Chemical warfare agents: Sulfur mustard, Lewisite, and the nerve agents appear to be the chemical warfare agents most frequently disposed off at sea. Multiple other type of agents including organoarsenicals, blood agents, choking agents, and lacrimators were dumped at sea, although in lesser volumes. Environmental concerns: Numerous geohydrologic variables contribute to the rate of release of chemical agents from their original casings, leading to difficult and inexact modeling of risk of release into seawater. Sulfur mustard and the organoarsenicals are the most environmentally persistent dumped chemical agents. Sulfur mustard in particular has a propensity to form a solid or semi-solid lump with a polymer coating of breakdown products, and can persist in this state on the ocean floor

    Nuclear weapons contain a wide variety of nonnuclear components - items that are not made from nuclear materials. These components comprise the majority of parts in nuclear weapons, including the ones needed to guide weapons to their targets, initiate the nuclear explosion, increase the weapons' explosive yield, and ensure the weapons' safety and security. DOE has three facilities, the Kansas City Plant in Missouri, the Mound Plant in Ohio, and the Pinellas Plant in Florida, that are dedicated primarily to nonnuclear activities and have unique manufacturing responsibilities. Some additional nonnuclear manufacturing activities are performed at the Rocky Flats Plant in Colorado, the Y-12 Plant in Tennessee, and the Pantex Plant in Texas. Descriptions of each plant and the activities they conduct are contained in appendix I of this report. In 1991, DOE began planning to reconfigure the nuclear weapons complex into one that is smaller, less diverse, and less expensive to operate. More specifically, DOE issued a reconfiguration study in January 1991 that set forth a detailed framework for making the complex smaller and more efficient. The study will lead to a complex-wide Programmatic Environmental Impact Statement (PEIS) on how best to reconfigure the complex. This statement is planned to be completed in late 1993. As part of the effort to analyze the reconfiguration, DOE's Assistant Secretary for Defense Programs directed the Albuquerque Operations Office in April 1991 to develop a nonnuclear consolidation plan to serve as input to the PEIS. There are a number of weaknesses in DOE's NCP. First, because the NCP's scope was limited to examining single-site consolidation alternatives, the decision to select Kansas City as the preferred option was made without analyzing other nonnuclear options. These options included down sizing and modernizing all facilities in place or maximizing consolidation by eliminating all nonnuclear sites and relocating their functions to a
