Bridging the nuclear structure gap between stable and super heavy nuclei

2009

International audience; Due to recent advances in detection techniques, excited states in several trans-fermium nuclei were studied in many laboratories worldwide, shedding light on the evolution of nuclear structure between stable nuclei and the predicted island of stability centered around spherical magic numbers. In particular, studies of K-isomers around the Z=100 and N=152 deformed shell closures extended information on the energies of Nilsson orbitals at the Fermi surface. Some of these orbitals originate from spherical states, which are relevant to the magic gaps in super-heavy nuclei. The single-particle energies can be used to test various theoretical predictions and aid in extrapo…

Kπ=8−isomers andKπ=2−octupole vibrations inN=150shell-stabilized isotones

2008

Isomers have been populated in {sup 246}Cm and {sup 252}No with quantum numbers K{sup {pi}}=8{sup -}, which decay through K{sup {pi}}=2{sup -} rotational bands built on octupole vibrational states. For N=150 isotones with (even) atomic number Z=94-102, the K{sup {pi}}=8{sup -} and 2{sup -} states have remarkably stable energies, indicating neutron excitations. An exception is a singular minimum in the 2{sup -} energy at Z=98, due to the additional role of proton configurations. The nearly constant energies, in isotones spanning an 18% increase in Coulomb energy near the Coulomb limit, provide a test for theory. The two-quasiparticle K{sup {pi}}=8{sup -} energies are described with single-pa…

Identification of excited states in119Ba

2000

Excited states have been identified in the very neutron-deficient ${}^{119}\mathrm{Ba}$ nucleus. Two bands have been observed, which are likely to be based on ${h}_{11/2}$ and ${(g}_{7/2}{d}_{5/2})$ neutron orbitals. Despite this being the first observation of excited states in ${}^{119}\mathrm{Ba},$ the bands extend to $(75/2)\ensuremath{\Elzxh}$ and $(79/2)\ensuremath{\Elzxh},$ respectively. The bands have been assigned to ${}^{119}\mathrm{Ba}$ using gamma-recoil and gamma--x-ray coincidences. Several quasiparticle alignments have been identified, involving neutron ${(h}_{11/2}{)}^{2}$ and proton ${(h}_{11/2}{)}^{2}$ aligned configurations. Furthermore, the bands show features which are r…

Jacqueline Woodson’s narrative style in The Other Side: An African American picture book for children

2012

The Other Side (2001) is a children’s story with multicultural characters and themes that can be regarded as an aesthetic exploration of the human experience in the process of the acquisition of knowledge. Following the Black Arts Movement, Jacqueline Woodson’s work portrays many of the issues that are present in the real world but seldom appear in children’s literature, such as racial division or interracial relationships. Using the metaphor of a fence, this African American author reveals issues of loneliness and friendship, inclusion and exclusion, and the overcoming of prejudice and segregation through the wisdom of Clover and Annie, an African American and a white girl, who become frie…

Nanocomposites based on esterified colophony and halloysite clay nanotubes as consolidants for waterlogged archaeological woods

2017

We have designed an innovative protocol for the consolidation of waterlogged archaeological woods by using acetone mixtures of halloysite clay nanotubes and a chemically modified colophony (Rosin). Firstly, we have investigated the thermal properties of HNTs/Rosin nanocomposites, which have been prepared by means of the casting method from acetone. The HNTs content have been systematically changed in order to study the influence of the inorganic filler on the thermal stability and glass transition process of Rosin. We have observed that the thermal properties of the hybrids are affected by the specific HNTs/Rosin interactions. Then, acetone dispersions of HNTs/Rosin composites at variable f…

Recovery of aliphatic low-molecular-mass carboxylic acids from hardwood kraft black liquor

2015

Abstract During alkaline pulping of wood, substantial amounts of carbohydrates-derived aliphatic carboxylic acids (formic and acetic acids together with various hydroxy acids) are formed and dissolved into the cooking liquor (“black liquor”). These acids with low heating values are considered to be potential feedstocks for the chemical industry but, due to many factors, their straightforward recovery as free acids from black liquor (pH 13–14) is difficult. In this paper, we outlined the partial recovery of volatile formic and acetic acids from the acidified birch ( Betula pendula ) kraft black liquor (pH approximately 2.5) by distillation, and the partial recovery of significant low-molecul…

Bretton Woods uudella vuosituhannella : kehityspolitiikka uusliberaalin käänteen jälkeen

2010

Maailmanpankki on ehkä merkittävin kehitysyhteistyön määrittelijä ja yhdessä toisen Bretton Woods -instituution, Kansainvälisen valuuttajärjestön IMF:n kanssa huomattava tekijä globaalissa talousjärjestelmässä. Instituutiot myöntävät talouspoliittisesti ehdollistettuja lainoja kehitysmaille, jotta ne pystyisivät kohentamaan elinolojaan sekä turvaamaan talouskasvun ja sitä myötä vähentämään köyhyyttä. Tutkimuksessani käyn läpi Bretton Woods- instituutioiden, etenkin Maailmanpankin, tapaa vähentää köyhyyttä kehitysmaissa. Tarkastelen, millaiseen ajatusmaailmaan sen voidaan katsoa perustuvan ja miten nykyinen, uusliberaali kehityspolitiikkaa on muotoutunut. Yksinkertaisin kysymys on, pystyykö …

The International Monetary System in the Context of the Actual Financial Crisis. Change Proposals

2013

The International Monetary System (I.M.S.) has a crucial role in economy, representing the frame for a sustainable development of the economic relationships between states, while contributing at the progress of the world’s economies. Nowadays, this system confronts large difficulties, as a consequence of the lack of financial disciplinary instruments, meant at regulation and coordination. The actual economic-financial crisis proved the limits of the present I.M.S., reason why it is now under “reconstruction”. In this direction, there is a series of reforms that can be implemented, so that the new architecture of the system is much more solid.
