Bastin et al (Reports, 5 July 2019, p. 76) claim that 205 gigatonnes of carbon can be globally sequestered by restoring 0.9 billion hectares of forest and woodland canopy cover. Reinterpreting the data from Bastin et al, we show that the global land area actually required to sequester human-emitted CO2 is at least a factor of 3 higher, representing an unrealistically large area.

The construction and general implications of a model with complete supersymmetric unification of the Standard Model matter content, interactions and families' replication into a single E8 gauge superfield in ten dimensions is presented. The gauge and extended Poincaré symmetries are broken through compactification of the T6/(Z3×Z3) orbifold with Wilson lines, which reduces the original symmetry an
The interaction between swimming micro-organisms or artificial self-propelled colloids and passive (tracer) particles in a fluid leads to enhanced diffusion of the tracers. This enhancement has attracted strong interest, as it could lead to new strategies to tackle the difficult problem of mixing on a microfluidic scale. Most of the theoretical work on this topic has focused on hydrodynamic intera
Cu(II) complexation at the water-goethite (alpha-FeOOH) interface was studied by XAFS, potentiometry, and sorption experiments. Thermodynamic data indicate that the initial Cu(II) sorption is not accompanied by release of a H+. As pH is raised, hydrolysis occurs, and a maximum of two H+ are released per sorbed ion. Sorption experiments also show that Cu(II) complexation is insensitive to variation
To detect effects of Cu pollution, the Cu tolerance of soil bacterial communities extracted from several vineyards located in NW Spain was measured. Bacterial community tolerance was estimated by means of the thymidine (TdR) and leucine (Leu) incorporation techniques using either IC50 values (the log of the metal concentration that reduced incorporation to 50%) or the percentage of activity at one
BACKGROUND: Vascular rings are a classical cause of tracheal and esophagus compression. We report the case of such an abnormality in an infant with neurofibromatosis. CASE REPORT: A 1 week-old male infant with a familial neurofibromatosis presented a stridor with severe respiratory distress. A vascular ring was demonstrated and operated on. The stridor persisted after surgery. A postoperative oeso
In this study using cross-sectional survey data from suburban and rural Scania, Sweden (N=24,847), we assessed how the recently validated index score of area-aggregated perceived green neighborhood qualities (Scania Green Score; SGS), and the five distinct qualities within this index were associated with three self-reported indicators of well-being: neighborhood satisfaction, physical activity and

The slippery slope argument is often used in (bio)ethical debates. It is an intriguing argument: it confronts us with fears, gut feelings, and fundamental values; it invites us to think about the future, and it forces us not only to look at a technology or policy in isolation but at the whole picture. Rhetorically it is attractive with its often vivid images and sweeping statements, sometimes deri
Background and purpose — With a rapidly increasing population in need of total knee arthroplasty (TKA), there is renewed interest in cost-saving all-polyethylene designs. Differences between metal-backed and all-polyethylene designs in initial component migration assessed by radiostereometric analysis (RSA), a proven predictor for late aseptic loosening, have been scantily reported. The purpose of
Dextrose syrups are produced from starch by liquefaction combined with saccharification. In the conventional production process, rotary vacuum filters (RVFs) with a diatomaceous earth (kieselguhr) coating as filter aid are often used for removal of the so-called mud phase after the liquefaction and saccharification step. This mud phase consists of insoluble impurities and suspended solids such as
