In this study we examined whether a training oriented to activate Epistemic Agency (Scardamalia, 2002) of teachers can allow them take the Knowledge Building (KB) perspective and realise appropriation use Forum (KF) environment. During project “Classi in rete”, promoted by INDIRE, 22 from primary lower secondary Abruzzi small schools participated an online discussion KF, focused on problems imp...

AIM To investigate the effect of temperature-humidity index (THI) on the expression pattern of heat-shock protein 72 (HSP72) mRNA of Sahiwal and Karan-Fries (KF) cattle in different THIs. MATERIALS AND METHODS Five different periods of a year were selected based on combinations of Tmax/Tmin, viz., P1: <20°C/<10°C; P2: >20°C/<10°C, P3: <30°C/<15°C; P4: >35°C/<20°C, and P5: >35°C/>20°C. The THI...

Administration of kefir and a kefir cell-free fraction (KF) to mice injected with breast tumor cells produced, locally in the mammary gland, different profiles of cells secreting cytokines. Here, the immune cell populations in mammary glands affected by the cyclic consumption of kefir or KF for 2 or 7 d were evaluated using a breast tumor model. Apoptosis was also assayed as another mechanism i...

Using the two-loop approximation of chiral perturbation theory, we calculate the momentum and density dependent nuclear spin-orbit strength Uls(p, kf ). This quantity is derived from the spin-dependent part of the interaction energy Σspin = i 2 ~σ ·(~q×~p )Uls(p, kf ) of a nucleon scattering off weakly inhomogeneous isospin symmetric nuclear matter. We find that iterated 1π-exchange generates a...

Nanoscale pores are a tool for single molecule analysis of DNA or RNA processing enzymes. Monitoring catalytic activity in real time using this technique requires that these enzymes retain function while held atop a nanopore in an applied electric field. Using an alpha-hemolysin nanopore, we measured the dwell time for complexes of DNA with the Klenow fragment of Escherichia coli DNA polymerase...

Knowledge of the mechanisms of interaction between self-aggregating peptides and nucleic acids or other polyanions is key to the understanding of many aggregation processes underlying several human diseases (e.g., Alzheimer's and Parkinson's diseases). Determining the affinity and kinetic steps of such interactions is challenging due to the competition between hydrophobic self-aggregating force...

Spectral anomaly for interacting Fermions is characterized by the spectral function A([k − kF ], ω) satisfying the scaling relation A(Λy1 [k − kF ],Λy2ω) = ΛyAA([k − kF ], ω), where y1, y2, and yA are the exponents defining the universality class. For a Fermi liquid y1 = 1, y2 = 1, yA = −1; all other values of the exponents are termed anomalous. In this paper, an example for which y1 = 1, y2 = ...

In this paper we study the properties of a gas of fermions coupling to a U~1! gauge field at wave vectors q,L!kF at dimensions larger than 1, where L!kF is a high-momentum cutoff and kF is the Fermi wave vector. In particular, we shall consider the e2→` limit, where charge and current fluctuations at wave vectors q,L are forbidden. By generalizing a method reported in a previous paper @Phys. Re...

We present the expression for the quasiparticle vertex function (KF ,PF ) (proportional to the Landau interaction function) in a 2D Fermi liquid (FL) near an instability towards antiferromagnetism. This function is relevant in many ways in the context of metallic quantum criticality. Previous studies have found that near a quantum critical point, the system enters into a regime in which the fer...
