Okręty podwodne typu Vanguard jako podstawa brytyjskiego systemu odstraszania militarnego w XXI wieku
2016
W świecie pozimnowojennym arsenał atomowy bogatych państw Zachodu przestał odgrywać decydującą rolę w polityce międzynarodowej. Nie znaczy to jednak, iż państwa te całkowicie zrezygnowały z tego narzędzia wywierania wpływu i wyznacznika pozycji siły. Broń atomowa w XXI w. nadal pozostaje najbardziej śmiercionośnym narzędziem pozostającym w arsenale wojskowym. W związku z tym każde państwo dysponujące tego typu uzbrojeniem poszukuje co rusz nowych metod i środków przenoszenia, użycia i modernizacji tejże. W przypadku Wielkiej Brytanii sytuacja jest szczególna, ponieważ flota strategicznych okrętów podwodnych o napędzie atomowym typu Vanguard jest jedynym brytyjskim rodzajem uzbrojenia zdolny…
Influence of accelerated ageing conditions on the process of polyolefines degradation
2003
The process of polymers weathering and the methods of polymers weathering and accelerated ageing investigations were characterized. Accelerated ageing tests of polyethylene and polypropylene samples have been done in laboratory conditions. The ageing time (up to 400 h) influence, at various levels of ageing factors: UV radiation intensity (80—190 W/m2), temperature (35—55 °C) and humidity (30—90%), on the changes of the structures of polymers investigated (shares of carbonyl and olefinic groups from FT-IR spectra — Fig. 1, 2, 4 and 5), on the changes of polymers molecular weights (Fig. 3 and 6, Table 1) and on the changes of mechanical properties during tension (Table 1) has been investigat…
Observacions sobre la posició dels subjectes postverbals en català i castellà
2007
This is a comparative study of the different positions of postverbal subjects in two closely related languages that nevertheless show clear differences in this respect. The comparative study will allow us to reject the idea that postverbal subjects in Romance languages are in a unique in situ position Spec VP as has been proposed recently (Motapayane1995, Ordóñez 1998, Costa 2000, Alexiadou i Anagnostopoulou 2001, Cardinaletti 2001). On the contrary, this study will show clearly that there is a need for two positions for postverbal subjects in order to understand the parametric differences between Catalan and Spanish. The general hypothesis will be that the subjects can access a higher Spec…
The paradox of endogenous poverty line in the poverty indices
2007
february 23-25, 2007; When measuring poverty, the poverty line is considered to be relatively determined as a percentage of the median income or as a percentage of the average income so as to allow international comparisons. The poverty line relative to the median income may be described as endogenous in contrast with the poverty line relative to the average income which may be described as exogenous because it is independent of the normalized distribution of incomes. As the existing literature is focused on the properties of the indices but not on the respective interest of the endogenous and exogenous poverty lines, this paper compares the two definitions of the relative poverty. The Rela…
S. Toscano, Tolle Divitem. Etica, Società e Potere nel De Divitiis, Catania, Edizioni del Prisma, 2006
2010
Review of the monograph by S. Toscano that proposes an original interpretation of De Divitiis, a text generally linked to the environment of the Pelagian cells of Sicily.The book is divided into three parts: one focusing on the ideology of wealth; one on De Divitiis' society; the last on power dynamics.
When other rules defend dissidents : the situation of Protestants and Orthodox Christians in the Polish - Lithuanian Commonwealth of the Saxon era
2018
The article address the problem of limiting the rights of Protestants and other non-Catholic Christian denominations during the reigns of two kings from the Wettin dynasty - King Augustus II (1697-1733). The process started as early as the second half of the 17th century, but it was fully accomplished in the years 1717-1736. In the article the author discussed the resolutions of the sejms and other legal acts introduced at that time, the aim of which was to eliminate dissenters from public life. The Polish monarchs were inert towards the process. It was the rulers of non - Catholic European states (Prussia, Russia and Great Britain) that helped Protestants an Orthodox Christans in Poland
Pressure support ventilation + sigh in acute hypoxemic respiratory failure patients: Study protocol for a pilot randomized controlled trial, the PROT…
2018
Background Adding cyclic short sustained inflations (sigh) to assisted ventilation yields optimizes lung recruitment, decreases heterogeneity and reduces inspiratory effort in patients with acute hypoxemic respiratory failure (AHRF). These findings suggest that adding sigh to pressure support ventilation (PSV) might decrease the risk of lung injury, shorten weaning and improve clinical outcomes. Thus, we conceived a pilot trial to test the feasibility of adding sigh to PSV (the PROTECTION study). Methods PROTECTION is an international randomized controlled trial that will be conducted in 23 intensive care units (ICUs). Patients with AHRF who have been intubated from 24 h to 7 days and under…
Early warning system in logistics project management
2017
Risk management is a vital process in all complex logistics project management. We discuss the concept of early warning system EWS dedicated to logistics project, which enable management under the conditions of uncertainty and risk. The complexity and uniqueness of the logistics projects as well as the discontinuity of the effects in the environment of goods and services, significantly impact the inability to eliminate the risks and subsequently lead to changes during execution. The introduction into companies and supply chains things such as: principles, methods, mechanisms of knowledge management and project risk, e.g. by implementing into the logistics project management the early warnin…
A Stochastic Decision Process Model for Optimization of Railway and Tramway Track Maintenance by means of Image Processing Technique
2013
One of the key targets for an efficient transport network management is the search for proper maintenance policies to guarantee acceptable safety and quality standards in the travel and to optimize available resource allocation. Methodologically, the proposed model presented in this paper uses the stochastic dynamic programming and in particular Markov decision processes applied to the rail wear conditions for the railway and tramway network. By performing the integrated analysis of the classes of variables which characterize the rail quality (in terms of safety), the proposed mathematical approach allows to find the solutions to the decision-making process related to the probability of det…
Balancing food, activity and the dangers of sunlit nights
2019
Living in northern latitudes poses challenges to the animals that live in those habitats. The harsh environment provides a short breeding season where the sunlit summer nights provide little reprieve from visibility to predators and increased risk. In this paper, we tested the activity and food choice patterns of bank voles Myodes glareolus in early spring season, categorized by 18 h of daylight and 6 h of dusk in every day cycle. We found that territorial females showed a less predictable pattern of activity than males that were most active during the hours of dusk. The voles also showed preference to forage on high carbohydrate foods at sunset, while switching over to a more protein and f…
