Abstract  

In northern part of Indian sub-continent, As related environmental and health issues receive attention from all over the world. Forty-eight sediment samples were collected from the Ganga Alluvial Plain (GAP) and its weathering products (from the Gomati River) for the study of As distribution and mobilization. These sediment samples were analyzed by Instrumental Neutron Activation Analysis (INAA) method using Cirus Research Reacter of Bhabha Atomic Research Centre, Mumbai. Average As concentrations in the GAP sediments (10.44 mg kg−1), the Gomati River bed sediments (1.36 mg kg−1) and the Gomati River suspended sediments (5.30 mg kg−1) were reported. Significant decrease of As content from the alluvial sediments to the river sediments is a clear indication of its mobilization by chemical weathering processes of mineral biotite. Present study demonstrates the importance of INAA for quantification and mobilization of As and improves our understanding related to As related environmental issues in northern India and elsewhere.

A felületes thrombophlebitist hosszú időn át meglehetősen jóindulatú betegségnek tartották. Újabban, amióta a diagnózishoz egyre gyakrabban használnak duplex ultrahangtechnikát, kiderült, hogy a betegség veszélyesebb, mint ahogy azt eddig gondoltuk. A thrombosis az esetek 6–44%-ában a mélyvénákra terjed, tüdőembóliát pedig a betegek 1,5–33%-ánál észleltek. Minden negyedik betegnél alakul ki vénás thromboemboliás szövődmény. A diagnózis klinikai, de a duplex ultrahangvizsgálatot mindig el kell végezni a thrombus kiterjedésének meghatározására, a mélyvénás thrombosis kizárására. Ezzel a vizsgálattal ellenőrizzük később is a betegeket. Ultrahanggal mindkét lábat meg kell vizsgálni, mert egyidejű mélyvénás thrombosis az ellenoldali végtagon is kialakulhat. A betegség két formáját lehet megkülönböztetni: felületes vénás thrombosis varicosus vénákon vagy varicositas nélkül. A spontán, nem varicosus formában, különösen, ha a folyamat migráló vagy kiújuló, a betegek gondos kivizsgálásra szorulnak, azért, hogy a malignus betegségeket és a thrombophiliát kizárjuk. A kezelési lehetőségeket a legújabb nemzetközi konszenzus alapján foglaljuk össze. Az amerikai és a német útmutatók hasonlóak. A kompresszió és a mobilizáció a terápia sarkköve. Rövid szegmentű thrombosisnál a nem szteroid gyulladáscsökkentő gyógyszerek hatásosak. Hosszabb szegmentnél előnyösebbek a kis molekulasúlyú heparinok. Az új, orális antikoagulánsokkal végzett kezelésre vonatkozó információval nem rendelkezünk. A jövőben ezek a gyógyszerek ebben az indikációban is hatásosak lehetnek. Ha a thrombus a saphenofemoralis vagy saphenopoplitealis junctióhoz közel van, crossectomiát (magas lekötést) kell végezni vagy terápiás dózisban kis molekulasúlyú heparint kell adni. Ne használjuk a felületes thrombophlebitis kifejezést, mert nem a gyulladás és fertőzés a patológia primer tényezője. Felületes vénás thrombosis az új, helyes elnevezés, azért, hogy ne adjunk feleslegesen antibiotikumokat, és elkerüljük azt a téves feltételezést, hogy a felületes vénás thrombosis benignus betegség.

Abstract  

Mobility of137Cs was investigated in columns of calcareous loam and clay soils leached under river water, NH4OAc, KCl, CaCl2, and EDTA. Fractionation of Cs into ten sequential fractions was accomplished in the leached soils as well as in soil samples received carrier-free137Cs and incubated for 60 d. At the end of 90 d of leaching with river water and CaCl2, the bulk of Cs applied (>97%) was found to remain in the upper 1 cm of soil columns. On the other hand, the reduction in Cs concentration was approximately 30% with NH4OAc, 18% with KCl, and 10 to 25% with EDTA. The major soil constituents appeared to be responsible for retaining Cs were clay, silt, and Fe oxides. The leaching consistently increased the magnitude of fractions bound to clay minerals and in most cases decreased the fractions of water soluble, exchangeable, carbonate, and organic matter.

The diazotrophic heterocystous cyanobacterial strains of four different taxonomic groups were able to grow under inorganic-P-limited (P-stress) condition with a little cell biomass, which was supported by the stored polyphosphate granules. Nitrate-N could support the growth of all the strains under P-limitation, which acted as an important nutrient, and an able support to overcome P-stress. All the strains under P-limitation synthesised the phosphomonoesterase enzyme and the resultant activity differs among the strains. Almost all the cyanobacteria investigated showed potential to mobilise organic-P substrates such as p-nitrophenyl phosphate (p-NPP), glucose-6-phosphate (G-6-P) andb-glycero phosphate (Gly-P) as evident in the diminishing PMEase activity and growth. Among the strains, Calothrix brevissima and Anabaena flos-aquae behaved as a novel organism to survive under P-stress and solubilise organic-P substrates.

In the 1930s in Hungary, the periodical Magyar Szemle (Hungarian Review) ranked as the foremost intellectual review of conservative thinking. Edited by the pro-establishment historian Gyula Szekfű, the journal provided important intellectual ammunition to the traditionalists of the right, in other words those who for various reasons sought to hold on to István Bethlen’s version of moderate conservatism in ideology and a parliamentary system of limited pluralism and authoritarian checks in practice. The 1930s, however, bore witness to several challenges to the Horthy regime. The rise of the extreme right and the emancipatory (though often also fervently nationalist) program of the so-called népi (populist or narodniki ) writers presented coherent political alternatives to the prevailing order for the first time since the marginalization and emaciation of the left in the wake of the 1918–19 revolutions. Simultaneously, the country had to grapple with the emergence of Nazi Germany as an expansionist great power in the region. In this complicated situation, authors of Magyar Szemle confronted what they perceived as a dual threat: the increasing appeal of German imperialism and German political and historical thinking. Many intellectuals of the time, feeling that the German political challenge should be resisted through the adoption and adaptation of innovative German thinking on politics and history, espoused the new ideologies emanating from the unquestioned cultural center of Central Europe in some form. Magyar Szemle , however, emerged as a hub for public intellectuals who sought to hold on to a conservatism both more traditional and more open to some of the ideas of liberalism and who refused to abandon the established view of Hungarian history for a more ethnically conscious vision of the past. In the context of the dual German challenge of the 1930s, Magyar Szemle represented a site of intellectual resistance not so much against direct German political ambitions but against the new wave of German political thought and interpretations of history.

Abstract  

Specific extraction studies in our laboratory have shown that iron and manganese oxide- and alkaline earth sulfate minerals are important hosts of radium in uranium mill tailings. Iron- and sulfate-reducing bacteria may enhance the release of radium (and its analog barium) from uranium mill tailings, oil field pipe scale [a major technologically enhanced naturally occurring radioactive material (TENORM) waste], and jarosite (a common mineral in sulfuric acid processed-tailings). These research findings are reviewed and discussed in the context of nuclear waste forms (such as barium sulfate matrices), radioactive waste management practices, and geochemical environments in the Earth's surficial and shallow subsurface regions.

In modern Shi’i Islam, power constitutes a major concern for thinkers and movements alike. Above all, Muham mad Husayn Fadlallah stands as the most systematic Shi’i thinker who produced an Islamic theory of power. The present article analyses Fadlallah’s concept of social power. In Islam and the Logic of Power (al-Islam wa-mantiq al-quwwa), he emphasised the importance of social solidarity, justice, and the obligation of “commanding right and forbidding wrong” as a means to create the ideal society. For him, this social model has are ciprocal relation to social power. Muhammad Husayn Fadlallah tells the tale of two societies: the weak and the strong, arguing that beliefs, unity and values determine the power of a community. He claims that the strong society is best illustrated by the first Islamic community. He confronts it with the weak society which lacks unity and solidarity — echoing to a great extent contemporary Lebanon. Fadlallah’s social theory — embedded in his theology of power — transforms spiritual power into a collective deployment of action. He draws on a wide range of elements (Sunni, Shi’i and Marxist) to create a coherent system of power in which social power is a mediator between the ideology of power and its political manifestation.
