Sabkha Ecosystems
This is the fourth volume of the sabkha ecosystem series in Tasks for Vegetation Science. More than ten years have passed since the publication of the first volume, dealing with the Arabian Peninsula and adjacent countries. Volume two provided information on West and Central Asia, volume three on Africa and Southern Europe, where a lack of scientific capacity in this specialized field of saline dry lands was noticed. This is why volume three was comparatively thin. For the current volume however, we had almost thirty contributions, highlighting the importance of halophyte research and development, with a view to establishing pilot-farms, for food production, biofuel, anal...

Sabotage in the Arctic
The story of Australian-born Sir Hubert Wilkins and the Nautilus is usually a brief footnote, if mentioned at all, of Arctic exploration history. However, it is a tale of daring enterprise and of men captivated by the pursuit of noble deeds. Having leased and extensively modified a decommissioned vintage World War I U.S. Navy submarine, the Wilkins-Ellsworth Trans Arctic Submarine Expedition of 1931 was marked by controversy from its inception. Many considered it a huge publicity stunt, especially the planned rendezvous at the North Pole with the German airship Graf Zeppelin. The Nautilus did make it into the Arctic but suspected sabotage ended Sir Huberts quest to ...

<b>Physical Mesomechanics And Spectrum Of Metal Surface Layer Excitation At Friction Process With Heavy Loading</b><br /> <i>A.Kh. Janahmadov, N.G. Javadov</i><br /> The paper reviews the physical mesomechanics of structurally inhomogeneous media, de- veloped on the verge of continuum mechanics (macro level) and physics of plasticity and strength of deformable solids (micro level). According to the concept of the structural level of deformation, at friction the surface layer of deformable solids is an independent leading functional subsystem. It is shown that with an increase of the deformation level of material, it develops autonomous processes (plasticity waves) inside,...

<b>The Creation Of Fluid And Gas Mechanics Basis In The Micro-Cracked Channel</b><br /> <i>R.S. Gurbanov, M.A. Mammadova, A.A. Hajiyev</i><br /> There are experimental investigations of the fluids flow in the small-sized channels, the hydraulic resistances results of which are more than the estimated ones according to theoretical formulas and different supposed explanations without the quantitative evolution have been given in the reference. Taking into consideration this situation in the mechanics we were conducted the experiments in special developed unit with different fluids: water, viscous and anomalous oils.<br /> The results of the numerous experimental investigati...

Javadov&#xa0;</i><br /> The additional quantitative research tools are developed to examine the surface roughness: the fractal dimension of bearing surface curvature and the fractal dimension of profilograms. These values are used to classify the contact interaction modes of the frictional metal elements and to diagnose the type of contact according to the fractal dimension scale by describing the main three types of contacts: elastic, elastic-plastic, plastic.<br /> <b></b><br...

<b>Studying On Stability Of Piezoelectric Actuators Of Initial Alignment System Accelerometers&#xa0;</b><br /> <i>A.M. Pashayev, T.I. Karimli, V.A. Neymatov&#xa0;</i><br /> The article investigates the servo actuator system of the initial alignment of the piezoelectric accelerometers in automatic operational mode, which eliminates the parasitic transverse sensitivity. There were developed the transfer functions of the piezoelectric drive of the turntable, built and performed a simulation modeling. The resulting oscilloscopes of the simulation model confirm the reliability of the proposed calculation method for the position regulation parameters, to ensure the necessary na...

Sai cosa mangi?
Cosa mangia l’America nell’era moderna? Probabilmente molte delle cose che mangeremo anche noi nel prossimo futuro. <br /><br />Ormai la dinamica dei flussi è chiara: l’hamburger e la Coca Cola sono solo i simboli di un modello di consumo che, con diverse sfaccettature, ha definitivamente contaminato la nostra cultura del cibo. Se per noi gli spaghetti sono intoccabili e la pizza continua a essere il più gettonato tra i fast food, è comunque vero che le giovani generazioni sentono irresistibile il richiamo del cibo made in USA. All’insegna dell’intercultura e del mercato globale, ci troveremo sempre di più a fare i conti con prodotti per noi alieni come i Marshmallow (le ...

Samodzielne myślenie
Jaka przyszłość czeka naszą cywilizację? Najwyższy czas, by każdy z osobna zadał sobie to pytanie i zastanowił się, co możemy zrobić już dziś, żeby wizja przyszłości znów stała się obietnicą a nie zagrożeniem. Autor, Harald Welzer, znany niemiecki psycholog społeczny prezentuje bezwzględną analizę społeczeństwa zakażonego wirusem totalnej konsumpcji i politycznego paraliżu. Jednocześnie Welzer pokazuje wiele konkretnych i intrygujących sposobów pozwalających każdemu z nas stać się politycznie aktywnym obywatelem i poważniej traktować siebie i własne interesy. Okazuje się, że pierwszy krok wcale nie jest taki trudny – wystarczy zacząć samodzielnie myśleć!

Samotna planeta
"Samotna planeta" to krótka historia o powstaniu świata i miejscu naszej planety w Układzie Słonecznym. Książka przenosi nas w daleką przeszłość, pokazując, jak przypuszczalnie mogło wyglądać tworzenie się warunków do rozwoju życia na Ziemi. Mimo prowadzonych od dawna badań naukowych dotyczących jej rozwoju, jak dotąd nie udało się jeszcze tego wyjaśnić. Autor sądzi, że mogło to wyglądać zupełnie inaczej, niż jest to powszechnie nam przedstawiane. Jak zmieniała się Ziemia? Dlaczego w porównaniu do innych planet tylko na niej występuje życie? Dlaczego jest dla nas tak ważna i musimy o nią należycie zadbać? Na te i inne pytania odpowiada tekst Ryszarda Pr...

Sans le nucléaire on s'éclairerait à la bougie
Des OGM au nucléaire et au téléphone mobile, nous vivons à l’ère de la technoscience. Soumise aux impératifs du marché, étroitement dépendante des lobbies industriels, cette alliance très efficace de science et de marketing a une tendance naturelle à confondre profit et bien public, précipitation et progrès. Cela suscite des expressions mille fois entendues mais rarement analysées : « le nucléaire ne pollue pas », « sans les OGM, la planète va mourir de faim » ou « les pesticides sont indispensables à l’agriculture ».Jean-François Bouvet, biologiste et grand amateur de chasse aux idées reçues, et Corinne Lepage, eurodéputée et spécialiste des questions environnementales, ...

Santé, médecine, société
Ne mourra-t-on bientôt plus que par manque de savoir-vivre — et non plus de maladie ? Les progrès considérables de la médecine depuis un demi-siècle se traduisent par un allongement continu de la durée de vie. Les performances extraordinaires de l’imagerie médicale, mais aussi une compréhension toujours plus subtile des processus biologiques permettent au cancérologue Lucien Israël, président de l’Académie des sciences morales et politiques en 2007, de prédire qu’un jour prochain, les médecins pourront dire à leurs patients : « Ce n’est pas grave, c’est un cancer ».<br />Pourtant tout ne va pas pour le mieux dans le monde de la santé. L’enseignement de la médecine souffre...
