The Impact

Differences between the territories in economic-geographical situation, socioeconomic development, and political conditions of economic activity, the accumulated knowledgebase and competences, generate nonuniformity of the innovation space, where each region is unique and has its own innovative trajectory of innovative development trajectory. The subject of this research is the the process of formation and development of the regional innovation system (RIS) of Primorsky Region. The hypothesis is advanced that the RIS of Primorsky Region has certain peculiarities substantiated by the impact of economic-geographical location, which are reflected in engraining the specificity of marine management in localized innovation processes. The object of this research is the Kaliningrad Oblast located on the coast of the Baltic Sea. The article covers the period from 1945 to 1990, which allowed determining the peculiarities of the three stages of the life cycle of RIS  (origin, development, and maturity), as well as assessing the influence of the factor of coastal location  upon them. The author examines the qualitative and statistical data that characterize the five components of RIS: human resources, infrastructure, research and development, innovation environment, and framework conditions. The novelty of this work lies in application of comprehensive approach towards studying life cycle of RIS in its structural complexity in different time periods, as well as in consideration of coastal specificity of the economy. It is demonstrated that the RIS of Kaliningrad Oblast of the Soviet period specialized in marine management, formed as a result of concerted efforts of the government.

The Impact

There remains uncertainty about the legal and policy tools, processes and institutions needed to support ecosystem-based marine management (EBM). This article relies on an interdisciplinary study of ecosystem-based language and approaches in the laws and policies of New Zealand, Australia and Chile, which uncovered important lessons for implementing EBM around the need to accept regulatory fragmentation, provide effective resourcing, respect and give effect to Indigenous rights, and avoid conflating EBM with conventional approaches to marine spatial planning. We suggest a new way of thinking about EBM as a ‘relational’ process; requiring laws, policies and institutions to support its dynamic process of dialogue, negotiation and adjustment. We argue that relational EBM can be best supported by a combination of detailed rule and institution-making (hooks) and high- level norm-setting (anchors). With its focus on relationships within and between humans and nature, relational EBM may enable new ways to secure cross-government collaboration and community buy-in, as well as having inbuilt adaptability to the dynamics of the marine environment and the impact of climate change at different scales.

Reef Ecosystem

Mo’orea’s reefs have rebounded from environmental disturbance throughout the years largely due to herbivorous fish that deter damaging algal blooms. This resilience suggests herbivorous fishes act as a keystone species in the coral reef ecosystem, and the greater island community of Mo’orea. Parrotfish support reef health and stability, and reefs support the development of the local economy by way of tourism and access to medicine, nourishment, and protection. Because island communities rely heavily on coral reef ecosystems, identifying the impact of fishing on the morphology and ecosystem function of parrotfish in a time of marine management and demographic transition can increase our knowledge of the vulnerability and resilience of these complex socio-ecosystems. The 2016 study reported here seeks to understand to what extent changes in fisheries management and off-take rates have affected the historically sustainable relationship between Mo’orea’s fishing population, the lagoon’s supply of larger-sized parrotfish, and the ecological stability of the greater coral reef ecosystem. Specifically, this study measured average parrotfish size at various fishing zones and paired Marine Protected Areas (MPAs) around the island, and then used participatory surveys to quantify fishermen observation of changes in parrotfish size since they started fishing. Both field data and participatory survey data show a decrease in parrotfish size since the establishment of MPAs. Island-wide, parrotfish also appear to be smaller in fished sites than in MPAs. Results suggest that the joint effect of zoning, catch-size enforcements and increased fishing pressure have caused a size-selection of parrotfish in the fishing zones of studied lagoons. These findings highlight the vulnerability of Mo’orea’s coral reef ecosystem to transitions in marine management strategy and size-selective fishing.

The Impact

The phenomena accompanying the impact of large meteorites on the surface of the Moon or of the Earth can be examined on the basis of the theory of explosive phenomena if we assume that, instead of an exploding meteorite moving inside the rock, we have an explosive charge (equivalent in energy), situated at a certain distance under the surface.

The term geo-sciences has been used here to include the disciplines geology, geophysics and geochemistry. However, in order to apply geophysics and geochemistry effectively one must begin with a geological model. Therefore, the science of geology should be used as the basis for lunar exploration. From an astronomical point of view, a lunar terrain heavily impacted with meteors appears the more reasonable; although from a geological standpoint, volcanism seems the more probable mechanism. A surface liberally marked with volcanic features has been advocated by such geologists as Bülow, Dana, Suess, von Wolff, Shaler, Spurr, and Kuno. In this paper, both the impact and volcanic hypotheses are considered in the application of the geo-sciences to manned lunar exploration. However, more emphasis is placed on the volcanic, or more correctly the defluidization, hypothesis to account for lunar surface features.

AbstractWhilst lithopanspermia depends upon massive impacts occurring at a speed above some limit, the intact delivery of organic chemicals or other volatiles to a planet requires the impact speed to be below some other limit such that a significant fraction of that material escapes destruction. Thus the two opposite ends of the impact speed distributions are the regions of interest in the bioastronomical context, whereas much modelling work on impacts delivers, or makes use of, only the mean speed. Here the probability distributions of impact speeds upon Mars are calculated for (i) the orbital distribution of known asteroids; and (ii) the expected distribution of near-parabolic cometary orbits. It is found that cometary impacts are far more likely to eject rocks from Mars (over 99 percent of the cometary impacts are at speeds above 20 km/sec, but at most 5 percent of the asteroidal impacts); paradoxically, the objects impacting at speeds low enough to make organic/volatile survival possible (the asteroids) are those which are depleted in such species.

AbstractA large amount of CO has been detected above many SL9/Jupiter impacts. This gas was never detected before the collision. So, in our opinion, CO was released from a parent compound during the collision. We identify this compound as POM (polyoxymethylene), a formaldehyde (HCHO) polymer that, when suddenly heated, reformes monomeric HCHO. At temperatures higher than 1200°K HCHO cannot exist in molecular form and the most probable result of its decomposition is the formation of CO. At lower temperatures, HCHO can react with NH3 and/or HCN to form high UV-absorbing polymeric material. In our opinion, this kind of material has also to be taken in to account to explain the complex evolution of some SL9 impacts that we observed in CCD images taken with a blue filter.

AbstractHydrogen cyanide polymers – heterogeneous solids ranging in color from yellow to orange to brown to black – may be among the organic macromolecules most readily formed within the Solar System. The non-volatile black crust of comet Halley, for example, as well as the extensive orangebrown streaks in the atmosphere of Jupiter, might consist largely of such polymers synthesized from HCN formed by photolysis of methane and ammonia, the color observed depending on the concentration of HCN involved. Laboratory studies of these ubiquitous compounds point to the presence of polyamidine structures synthesized directly from hydrogen cyanide. These would be converted by water to polypeptides which can be further hydrolyzed to α-amino acids. Black polymers and multimers with conjugated ladder structures derived from HCN could also be formed and might well be the source of the many nitrogen heterocycles, adenine included, observed after pyrolysis. The dark brown color arising from the impacts of comet P/Shoemaker-Levy 9 on Jupiter might therefore be mainly caused by the presence of HCN polymers, whether originally present, deposited by the impactor or synthesized directly from HCN. Spectroscopic detection of these predicted macromolecules and their hydrolytic and pyrolytic by-products would strengthen significantly the hypothesis that cyanide polymerization is a preferred pathway for prebiotic and extraterrestrial chemistry.

The Impact

Crushed and statically compressed Madagascar graphite that was explosively shocked at 425 kb by means of a planar flyer-plate is characterized by a black zone extending for 2 to 3 nun below the impact plane of the driver. Beyond this point, the material assumes the normal gray color of graphite. The thickness of the black zone is identical with the distance taken by the relaxation wave to overtake the compression wave.The main mechanical characteristic of the black material is its great hardness; steel scalpels and razor blades are readily blunted during attempts to cut it. An average microhardness value of 95-3 DPHN was obtained with a 10 kg load. This figure is a minimum because the indentations were usually cracked; 14.8 DPHN was measured in the gray zone.
