Reprogramming of gene expression in Escherichia coli cultured on pyruvate versus glucose
(Springer, 2019-07-30)
Previous studies revealed important roles of small RNAs (sRNAs) in regulation of bacterial metabolism, stress responses and virulence. However, only a minor fraction of sRNAs is well characterized with respect to the spectra ...
Understanding fatness in the public sphere of young students: social representations and emotional response
(Cadernos de Saude Publica, 2018)
This study examines how youth collectively represent fatness and determines the emotions it arouses. Understanding how fatness is socially constructed by young people is crucial to create programs that better deal with it. ...
Ideas de los estudiantes universitarios sobre las relaciones trabajo y energía en Mecánica en cursos introductorios de Física
(Sociedade Brasileira de Fisica, 2018)
Las relaciones entre trabajo y energía continúan siendo fuentes de problemas de
enseñanza/aprendizaje en los cursos introductorios de física a nivel universitario, ya que implican conceptos abstractos y habilidades de ...
El espacio poético en las Epifanías urbanas de Garaicoa
(Universidade de Lisboa, 2018-03)
La ciudad constituye tanto el espacio simbólico como el campo de juego desde el que Carlos Garaicoa desarrolla su práctica artística multidisciplinar. A continuación, analizaremos las piezas incluidas en la exposición ...
Orbital magneto-optical response of periodic insulators from first principles
(Springer, 2019-03-06)
Magneto-optical response, i.e. optical response in the presence of a magnetic field, is commonly used for characterization of materials and in optical communications. However, quantum mechanical description of electric and ...
Adaptive Downregulation of Cl-/HCO3- Exchange Activity in Rat Hepatocytes under Experimental Obstructive Cholestasis
(Public Library Science, 2019-02-21)
In obstructive cholestasis, there is an integral adaptive response aimed to diminish the bile flow and minimize the injury of bile ducts caused by increased intraluminal pressure and harmful levels of bile salts and ...
Removal of Tetracycline Pollutants by Adsorption and Magnetic Separation Using Reduced Graphene Oxide Decorated with Alpha-Fe₂O₃ Nanoparticles
(MDPI, 2019-02-26)
Nanocomposites of reduced graphene oxide (RGO) with ferromagnetic alpha-Fe₂O₃ nanoparticles have been prepared in-situ by thermal treatment. The structure and morphology of the hybrid material were studied by X-ray ...
Measurements of Branching Fraction and Direct CP Asymmetry in B-+/- -> (KSKSK +/-)-K-0-K-0 and a Search for B-+/- -> (KSKS0)-K-0 pi(+/-)
(American Physical Society, 2019-02-20)
We study charmless hadronic decays of charged B mesons to the final states (KSKSK +/-)-K-0-K-0 and (KSKS0)-K-0 pi(+/-) using a 711 fb(-1) data sample that contains 772 x 10(6) B (B) over bar pairs and was collected at the ...
Divalent EuRh2Si2 as a Reference for the Luttinger Theorem and Antiferromagnetism in Trivalent Heavy-Fermion YbRh2Si2
(Nature Publishing Group, 2019-02-15)
Application of the Luttinger theorem to the Kondo lattice YbRh2Si2 suggests that its large 4f derived Fermi surface (FS) in the paramagnetic (PM) regime should be similar in shape and volume to that of the divalent ...
First Measurements of Absolute Branching Fractions of the Xi(0)(c) Baryon at Belle
(American Physical Society, 2019-02-25)
We present the first measurements of absolute branching fractions of Xi(0)(c) decays into Xi(-)pi(+), Lambda K-pi(+), and pK(-)K(-)pi(+) final states. The measurements are made using a dataset comprising (772 +/- 11) x ...
