Soil fauna feeding activity in temperate grassland soils increases with legume and grass species richness

Edaphic fauna contributes to important ecosystem functions in grassland soils such as decomposition and nutrient mineralization. Since this functional role is likely to be altered by global change and associated shifts in plant communities, a thorough understanding of large scale drivers on below-ground processes independent of regional differences in soil type or climate is essential. We investig

Measurement of the low-mass Drell-Yan differential cross section at root s=7 TeV using the ATLAS detector

The differential cross section for the process Z/gamma* -> ll (l = e, mu) as a function of dilepton invariant mass is measured in pp collisions at root s = 7 TeV at the LHC using the ATLAS detector. The measurement is performed in the e and mu channels for invariant masses between 26 GeV and 66 GeV using an integrated luminosity of 1.6 fb(-1) collected in 2011 and these measurements are combined.

Induction of morphological changes in death-induced cancer cells monitored by holographic microscopy.

We are using the label-free technique of holographic microscopy to analyze cellular parameters including cell number, confluence, cellular volume and area directly in the cell culture environment. We show that death-induced cells can be distinguished from untreated counterparts by the use of holographic microscopy, and we demonstrate its capability for cell death assessment. Morphological analysis

The radiation pattern of a QCD antenna in a dense medium

We calculate the radiation spectrum off a q (q) over bar pair of a fixed opening angle theta(q (q) over bar) traversing a medium of length L. Multiple interactions with the medium are handled in the harmonic oscillator approximation, valid for soft gluon emissions. We discuss the time-scales relevant to the decoherence of correlated partons traversing the medium and demonstrate how this relates to

The Robotic Earthshine Telescope

Lund Observatory is presently designing and constructing a robotic telescope dedicated to studies of the Earth's albedo by measuring the ratio between the intensity of the dark and bright sides of the Moon. The telescope will operate both in broadband and narrow-band modes over the entire visible wavelength range and will transmit observational results back to the operation team over the Internet.

Resolvent estimates for non-selfadjoint operators with double characteristics

We study resolvent estimates for non-selfadjoint semiclassical pseudodifferential operators with double characteristics. Assuming that the quadratic approximation along the double characteristics is elliptic, we obtain polynomial upper bounds on the resolvent in a suitable region inside the pseudospectrum.

Application of geographic information technologies to historical landscape reconstruction and military terrain analysis of an American Revolution Battlefield: Preservation potential of historic lands in urbanized settings, Boston, Massachusetts, USA

Through funding from the National Park Service's American Battlefield Protection Program, geographic information technologies were employed to create a high resolution, spatially accurate representation of the 1775 landscape of Boston's Inner Harbor and to conduct a geospatial and temporal assessment of the location, extent, and preservation potential of an American Revolutionary War battlefield a

Extended producer responsibility in Thailand: Prospects for policies on waste electrical and electronic equipment

Waste electrical and electronic equipment (WEEE) sheds light on the dimmer side of production and consumption patterns in modern societies. The rapid increase in its quantity and complexity contribute to the challenges it poses to solid waste management systems. Several members of the Organisation for Economic Co-operation and Development (OECD) have relied on the principle of extended producer re

Getting Ready for the Marriage Market? A Response

Summary: Overweight and obesity constitute a major and increasing health and welfare problem throughout the world. Assessing the multifaceted mechanisms – biological, environmental and behavioural – behind this development is a crucial task in medical, social and economic sciences. We are, therefore, grateful to have been given the opportunity to, once again, discuss whether the risk of divorce ma

Assessing tourism's global environmental impact 1900-2050

This paper pioneers the assessment of tourism's total global resource use, including its fossil fuel consumption, associated CO2 emissions, fresh water, land, and food use. As tourism is a dynamic growth system, characterized by rapidly increasing tourist numbers, understanding its past, current, and future contributions to global resource use is a central requirement for sustainable tourism asses

In vitro preparation of amelogenin nanoparticles carrying nucleic acids.

Amelogenin, a matrix protein involved in biomineralization of enamel, can self-assemble to form nanospheres in a pH-dependent manner. Nucleic acids (single-stranded, double-stranded, and plasmid DNA, as well as RNA) could be co-precipitated with amelogenin, demonstrating a strong binding of nucleic acids to amelogenin. The amounts of co-precipitated nucleic acids were analyzed and binding levels u

Isolation and structural identification of glycopolymers of Bifidobacterium bifidum BIM B-733D as putative players in pathogenesis of autoimmune thyroid diseases

Bifidobacterium bifidum 791 (commercially available as B. bifidum BIM B-733D) cell-surface biopolymers (BPs) interact selectively with human serum thyroid peroxidase (TPO) and thyroglobulin (Tg) autoantibodies (anti-TPO and anti-Tg, respectively). BPanti-TPO and BPanti-Tg were isolated from the soluble fraction of B. bifidum BIM B-733D by affinity chromatography with anti-TPO or anti-Tg, respectiv
