Effects of reducing nutrient loads to surface waters within the Mississippi River Basin and the Gulf of Mexico: Topic 4 Report for the Integrated Assessment on Hypoxia in the Gulf of Mexico

The overall goal of this assessment was to evaluate the effects of nutrient-source reductions that may be implemented in the Mississippi River Basin (MRB) to reduce the problem of low oxygen conditions (hypoxia) in the nearshore Gulf of Mexico. Such source reductions would affect the quality of surface waters—streams, rivers, and reservoirs—in the drainage basin itself, as well as nearshore Gulf waters. The task group’s work was divided into addressing the effects of nutrient-source reductions on: (1) surface waters in the MRB and (2) hypoxia in the Gulf of Mexico.

Syntheses, structures and reactions of a series of beta-diketiminatoyttrium compounds

This paper describes the synthesis and selected reactions of a series of crystalline mono(beta-diiminato) yttrium chlorides 3a, 3b, 4a, 4b, 5a, 5b, 5c and 9. The X-ray structure of each has been determined, as well as of [YCl(L-4)(2)] (6), [Y(L-1)(2)OBut] (7) and [Y{CH(SiMe3)(2)}(thf)(mu-Cl)(2)Li(OEt2)(2)(mu-Cl)](2) (8).

A new species of Orinus (Poaceae) from Qinghai, China

A new species of Orinus Hitchcock, O. alticulmus L. B. Cai & Tong Lin Zhang, is described and illustrated. This species is endemic to Qinghai province, China, occurring at altitudes of 2450-2600 m on sandy soils. It resembles O. kokonorica (K. S. Hao) Tzvelev, but differs from that species by its slightly effuse panicles, longer spikelets usually with five or six florets, purple-yellow anthers, shorter caryopses, and the paleas usually longer than the lemmas. A key to the five species of the genus is provided.

Non-Uniform Reductions

We study properties of non-uniform reductions and related completeness notions. We strengthen several results of Hitchcock and Pavan and give a trade-off between the amount of advice needed for a reduction and its honesty on NEXP. We construct an oracle relative to which this trade-off is optimal. We show, in a more systematic study of non-uniform reductions, that among other things non-uniformity can be removed at the cost of more queries. In line with Post's program for complexity theory we connect such 'uniformization' properties to the separation of complexity classes.

Utility of telomerase-pot1 fusion protein in vascular tissue engineering.

While advances in regenerative medicine and vascular tissue engineering have been substantial in recent years, important stumbling blocks remain. In particular, the limited life span of differentiated cells that are harvested from elderly human donors is an important limitation in many areas of regenerative medicine. Recently, a mutant of the human telomerase reverse transcriptase enzyme (TERT) was described, which is highly processive and elongates telomeres more rapidly than conventional telomerase. This mutant, called pot1-TERT, is a chimeric fusion between the DNA binding protein pot1 and TERT. Because pot1-TERT is highly processive, it is possible that transient delivery of this transgene to cells that are utilized in regenerative medicine applications may elongate telomeres and extend cellular life span while avoiding risks that are associated with retroviral or lentiviral vectors. In the present study, adenoviral delivery of pot1-TERT resulted in transient reconstitution of telomerase activity in human smooth muscle cells, as demonstrated by telomeric repeat amplification protocol (TRAP). In addition, human engineered vessels that were cultured using pot1-TERT-expressing cells had greater collagen content and somewhat better performance in vivo than control grafts. Hence, transient delivery of pot1-TERT to elderly human cells may be useful for increasing cellular life span and improving the functional characteristics of resultant tissue-engineered constructs.

Uranium halide complexes in ionic liquids

We report here the syntheses, characterisation and electrochemistry of some 1-ethyl-3-methylimidazolium, [emim], uranium halide salts. The electrochemistry of the uranium halide salts were investigated in both basic and acidic haloaluminate ionic liquids (ILs). The solid state structures of the uranium chloride salts have previously been reported, but have now been re-evaluted using a new statistical model to determine the presence or absence of weak hydrogen bonding interactions in the crystalline state.

1948-1965: o declínio do paradigma clássico e a emergência do maneirismo de Hollywood

O presente trabalho, investiga as origens históricas e as características formais do maneirismo de Hollywood, através de uma análise da produção cinematográfica dos estúdios de Hollywood, entre o final da década de 1920 e o fim do chamado studio system (em meados da década de 1960). Tal como o maneirismo histórico, o maneirismo hollywoodiano constitui um fenómeno artístico complexo e contraditório, cujas origens remontam ao estilo germânico introduzido no cinema dos estúdios em final dos anos vinte, por cineastas europeus como F.W. Murnau, Paul Leni, Rouben Mamoulian e James Whale. Tendo eclodido no final da II Guerra Mundial, período que assinala o início crise do sistema social, cultural e industrial que havia originado o cinema clássico, o maneirismo de Hollywood nasceu de uma consciência do cinema em relação ao seu passado. Obrigado a concorrer com a chamada “modernidade” cinematográfica europeia e com a ficção televisiva (que se apropriara do modelo clássico), o cinema de Hollywood explorou novos temas e géneros cinematográficos e investiu na exibição da técnica e do aparato tecnológico, forçando os limites do paradigma clássico, através de uma retórica de efeitos maneiristas que, não implicando um corte radical com o classicismo, representou uma clara tentativa de renovação formal, levada a cabo por cineastas como Alfred Hitchcock, Vincente Minnelli, Douglas Sirk, Stanley Donen e Jerry Lewis. A coexistência de varias correntes estéticas no cinema do pós-guerra (1945-1968), período em que, a par das últimas grandes obras clássicas, o maneirismo enquanto manifestação estética emergiu como modelo dominante, permite-nos concluir que o chamado cinema “clássico” (do estúdios de Hollywood) incluiu também, desde cedo, um cinema maneirista.

Divinyldisiloxane and divinylsilane complexes of rhodium(I)

Reaction of the tetrakis(cyclooctene)rhodium(I) complex [{Rh(C8H14-c)2(μ-Cl)}2] with the appropriate divinyldisiloxane molecules (ViSiR2)2O (R=Me or Ph) yields, by displacement of the cycloctene ligands, the complexes [{Rh(ViSiR2)2O(μ-Cl)}2] (R=Me (1) or Ph (2)). These react further with a tertiary phosphine PR3 to give cis-[Rh{(ViSiR2)2O}(PR′3)Cl] (R′=Ph or C6H4Me-p). The complex cis-[{Rh(Vi2SiMe2)(μ-Cl)}2] (7) was similarly prepared by the displacement of ethylene from [{Rh(C2H4)2(μ-Cl)}2] by the divinyldimethylsilane Vi2SiMe2. X-ray molecular structures of the crystalline complexes 1, 2 and 7 show a distorted square planar Rh(I) environment, the CH2CH groups being orthogonal to this plane; 1 and 2 have the Rh–(ViSiR2)2O metallacycle in the chair conformation, but differ in the nature of the central Rh(Cl)RhCl core, which is planar for 1 and puckered for 2, but each of 1 and 2 is the rac-diastereoisomer, whereas 7 has the meso-configuration. In solution 1 and 2 exist as a mixture of isomers, probably the rac- and meso-pairs as established by multinuclear NMR spectral studies. A series of saturation transfer NMR spectroscopic experiments showed that the divinyldisiloxane ligands in [{Rh(ViSiPh2)2O(μ-Cl)}2] underwent a dynamic process involving the dissociation, rotation and then reassociation of the vinyl groups.
