Reciprocity towards groups : a laboratory experiment on the causes [PDF]

open access: yes, 2012
Field studies of conflict report cycles of mutual revenge between groups, often linked to perceptions of intergroup injustice. We test the hypothesis that people are predisposed to reciprocate against groups.

Medical Insurance and Free Choice of Physician Shape Patient Overtreatment: A Laboratory Experiment

open access: yes, 2014
In a laboratory experiment designed to capture key aspects of the interaction between physicians and patients in a stylized way, we study the effects of medical insurance and competition in the guise of free choice of physician.

The solution supramolecular structure of α2 → 8 polysialic acid suggests a structural cause for its low immunogenicity

open access: yesFEBS Letters, EarlyView.
α2 → 8 polysialic acid elicits poor immunogenicity. Small‐angle scattering shows a supramolecular structure with parallel‐chain binding, although in different forms at μm and mm calcium. The major histocompatibility complex requires molecular weights around 2000 Da to produce antibodies, and 2000 Da polysialic oligomers will bind in these structures ...

Biosafety and data quality considerations for animal experiments with highly infectious agents at ABSL-3 facilities

open access: yesJournal of Biosafety and Biosecurity, 2019
Animal models are crucial for the study of severe infectious diseases, which is essential for determining their pathogenesis and the development of vaccines and drugs.

European underground laboratories: An overview [PDF]

open access: yes, 2005
Underground laboratories are complementary to those where the research in fundamental physics is made using accelerators. This report focus on the logistic and on the background features of the most relevant laboratories in Europe, stressing also on the low background facilities available.

Laboratory experiments on whirlpools [PDF]

open access: yesProceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1948
Two vertical pipes, placed on the axis of an open circular tank and fitted with trumpet entries of different shapes, were used in turn as overflows. Water was led into the tank in such a way that the stream approaching the trumpet under test possessed tangential velocity, which caused a vortex to appear in and above the trumpet.

The Saccharomyces cerevisiae amino acid transporter Lyp1 has a broad substrate spectrum

open access: yesFEBS Letters, EarlyView.
In Saccharomyces cerevisiae, Yeast Amino acid Transporter family members mediate the import of amino acids, ranging from substrate specialists to generalists. Here, we show that the specialist transporter, Lyp1, has a broader substrate spectrum than previously described, with affinity constants spanning from micromolar to millimolar.

Experiments on Radioactivity in a Virtual Laboratory [PDF]

open access: yesarXiv, 2011
This paper shows how to run some experiments of physics, using a virtual laboratory. Such a laboratory is a website, equipped with objects to be measured and measuring instruments, simulated by means of Java Applets. Here we discuss in particular the case of a laboratory in which we can perform, on the Web, some experiments on radioactivity.
