Determination of Active Protection Measures against Fire in Wuse Market of the Federal Capital Territory of Nigeria

This paper presents a selection of deliverables of a research project intended to develop a technology demonstrator for an active protection system smart counterprojectile. Numerical simulations were completed to analyse the effects of geometry and weight of the counterprojectile warhead on the counterprojectile flight (motion) parameters. This paper investigates four variants of the counterprojectile warhead shape and three variants of the counterprojectile warhead weight. Given the investigated geometric and weight variants, the PRODAS software environment was used to develop geometric models of the counterprojectile warhead, followed by the determination of the model aerodynamic characteristics. The final deliverable of this work are the results of the numerical simulation of the counterprojectile motion along the initial flight path length. Given the required activation of the active protection system in direct proximity of the protected object, the analyses of counterprojectile motion parameters were restricted to a distance of ten-odd metres from the counterprojectile launching system.

Coenotic Diversity

Introduction. The highlands of the Ukrainian Carpathians belong to the territories with the highest concentration of rare species and coenotic diversity in Ukraine. Due to highland ecosystem transformation, a large number of populations and communities of rare species are under the threat of degradation and elimination. Climate change. At present, effective growth and development of plants begins 2–3 weeks earlier compared to the 1980–90s. Sharp seasonal distribution of precipitation causes negative changes in the highland water-body hydrology regime affecting freshwater populations of plankton crustaceans and amphibians. Demutative successions. During the first 10–20 years of the succession its influence on the structure and vitality of the majority of rare species populations is mostly positive, but 30–40 year-long demutations usually cause negative dynamics. Overgrowing results in the simplification of spatial structure and fragmentation, as well as decreasing of population density, disappearing of rare species from the community structure. Active protection measures should be locally implemented in protected territories: traditional type of grazing, mowing, and shrub or tree cutting in the cases of protection of extremely rare phytocoenoses and populations. Anthropogenic impact. Intensive recreation pressure causes digressive changes in numerous communities, which are located along the popular tourist paths to the glacial lakes, mountain summits etc. Unfortunately, the systematic violation of the protection regime in the highland zone of the Ukrainian Carpathians is obvious nowadays. Gathering medicinal and ornamental species poses a serious threat. Uncontrolled increase in the number of recreants in the highland areas for the last 5 years has destroyed its aquatic ecosystems more than in the previous 30–40 years. Usage of vehicles for recreation purposes (4×4, quads and motorcycles) refers to significant destructive factors for highland ecosystems. Protection measures. Population conservation and revival of communities is usually possible under the condition of moderate and short-term anthropogenic pressure. The visiting regime of the most popular highland sites must be put under control immediately, while mass ascensions must be completely forbidden.

An automobile intelligent auxiliary control system performance for comity pedestrians is analysed. For safety reasons, a car safety distance model which can distinguish pedestrians at the front zebra crossing line is proposed. The important features of the active protective comity pedestrian integrated control system are derived, which can accurately identify pedestrians or cyclists in front of you and distinguish safety behaviour characteristics. According to the system feedback, active protection measures are adopted. A control system based on the combination of infrared radar probe ranging system and image processing recognition system is studied. The innovative research on car avoiding pedestrians focuses on both the behaviour characteristics of the driver and the pedestrian. Dual protection of longitudinal anti-collision comity pedestrians and horizontal pedestrian protection early warning protection can be carried out through the system. The intelligent auxiliary control system is a control system that can ensure the safety of pedestrians at non-traffic signal intersections. The system embodies more intelligent and humane, and also provides innovative ideas for the research and development of new products.

Ecological Improvement

The Arctic is of great importance for the development of the country’s economy. At the same time, the active entry of industry into this region brings with it environmental risks. The most difficult issues for reducing environmental stress in this zone are the elimination of accumulated environmental damage, prevention and elimination of accidents. The important decisions made in the development of the Arctic provide for the implementation of environmental protection measures based on the national project “Ecology”. Large industrial enterprises located in the Arctic will play a significant role in this. To ensure conditions for the further development of the economy in this zone, it is necessary to intensify the work on cleaning up the contaminated areas, including the completion of a project for the ecological improvement of the Franz Josef Land archipelago. The issue of assessing and eliminating the consequences of accidents is relevant for the Arctic, but in this direction it is necessary to improve the regulatory and methodological base. Based on the results of the study, specific measures are proposed to improve the environmental situation in the Arctic, including: to organize scientific research to assess the accumulated and current and environmental damage in the Arctic, to form a separate subprogram “Elimination of accumulated environmental damage in the Russian Arctic for the period 2022–2030”; to prepare proposals for the allocation of directions in the structure of the Arctic Development Fund for environmental safety and elimination of accumulated and future environmental damage; to develop a modern regulatory and methodological base for the determination of damage; to settle issues of a regulatory and methodological nature in terms of assessment and elimination of the consequences of accidents to develop proposals on the use of public-private partnership mechanisms with state funding of measures aimed at the rehabilitation of environmentally unfavorable territories, the elimination of environmental damage in the Arctic.

Resumen: La Ley italiana núm. 47 de 2017, sobre disposiciones en materia de medidas de protección de menores extranjeros no acompañados, constituye el primer texto normativo que contempla de manera unificada la tutela de menas en la UE. Por un lado, esta ley establece un procedimiento multidisciplinar de identificación del menor y de determinación de la minoría de edad (art. 5). Por otro, destaca la figura del «tutor voluntario», institución protectora de los MENAs que llegan al territorio italiano (art. 11). Sin embargo, la falta de coordinación entre los estados miembros amenaza la eficacia práctica de estas previsiones normativas, cuya fuerza vinculante se queda ceñida al territorio italiano. Se plantea, entonces, la necesidad de armonizar las diferentes prácticas estatales a través de una intervención legislativa europea.Palabras clave: MENAs, identificación, tutor voluntario, Italia, Unión Europea.Abstract: The Italian Law n. 47 of 2017 on dispositions upon protection measures of foreign unaccompanied minors, represents the first normative text, which contemplates, in a uniform way, the protection of unaccompanied minors in the EU. On one side, it establishes a multidisciplinary proceeding for the identification of the minor and for the determination of his/her minor age (art. 5). On the other, it stand out the legal figure of a «volunteer guardian», institution that protect unaccompanied minors who arrive at the Italian territory (art. 11). However, the lack of coordination among Member States threats the practice efficacy of those legal provisions, which coercive force is confined through the Italian territory. We discuss upon the need of harmonizing the different states’ practices through a legislative intervention of the EU.Keywords: Unaccompanied foreign minors, identification, volunteer guardian, harmonisation, Italy, European Union.

Khorasan wheat occupies a special place in the group of new-old cereals (Triticum turgidum, ssp. Turanicum McKey). It is an ancient species, native to eastern Persia, that is very close to durum wheat by morphological characteristics. Investigations were carried out in agro ecological conditions of the eastern Srem, with two wheat populations with dark and bright awns as objects of study. The following morphological and productive characteristics were investigated: plant height (PH), spike length (SH), number of spikelets per spike (NSS), absolute weight (AW) and grain weight per spike (GW), seed germination (G) and grains yield (YG). Field micro-experiments were set on the carbonate chernozem soil type on loess plateau in 2011 and 2012. Hand wheat sowing was conducted in early March with drill row spacing of 12 cm. The experiment was established as complete randomized block system with four replications. Tending crops measures were not applied during the growing season. Plants were grown without usage of NPK mineral nutrients. Chemical crop protection measures were not applied, although powdery mildew (Erysiphe graminis) was appeared before plants spike formation in a small extent. The results showed that both populations have a genetic yield potential. In general, both populations manifested a satisfactory tolerance on lodging and there was no seed dispersal. Plants from bright awns population were higher, had longer spikes and larger number of spikelet?s per spike. However, plants from dark awns population had higher absolute weight and grains weight per spike, as well as grain yield per plant. Strong correlation connections were identified among the investigated characteristics. The determination of correlations, as well as direct and indirect affects, enabled easier understanding of the mutual relationships and their balancing in order to improve the yield per unit area.

Improve Water Quality

Bivalves play an important part in freshwater ecosystems and improve water quality; the thick-shelled river mussel Unio crassus is classified as a bioindicator. Unfortunately, the species is regarded as endangered and is under species protection in the whole of Europe. The reasons for the drastic decline of its populations are: considerable eutrophication of waters, anthropogenic influence in its broad sense and the presence of invasive species. The life cycle of U. crassus includes the stage of larva which is an obligatory parasite of fish. This makes it possible for the species to disperse and populate new territories but it limits the development to places where appropriate host species are available. Intensive measures have been taken in Poland to protect U. crassus, while in France numerous new localities of the species have been bar-coded. In 2010–2014 active protection measures were taken in southern Poland, including inventorying, studies of genetic diversity and reintroductions. The project contributed to the increase in population abundance and in the number of localities of the thick-shelled river mussel, which resulted in a twofold increase in the range of occurrence of the species in the river. The procedures presented here can and should be used in further restitution of U. crassus not only in Poland but also elsewhere in Europe.
