Interactive influence of light intensity and soil fertility on root-associated arbuscular mycorrhizal fungi

Soil nutrients and light have major effects on the economics of arbuscular mycorrhizal (AM) symbioses. This study tests the main and interactive effects of soil fertility and light on AM fungal community. We conducted a 3 year mesocosm experiment with a full two factorial design: light (full light or shade) and soil fertility (unfertilized or fertilized), on the Qinghai-Tibetan Plateau. Plant trai

Development and the documentation of indigenous knowledge: Good intentions in bad company?

There appears to be an increasing interest within library and information studies (LIS) in so-called indigenous or traditional knowledge. Discussions on usefulness and applicability of indigenous knowledge in development seem to be motivating electronic documentation and the creation of databases. Often, definitions provided by international organisations are drawn on unquestioningly, while power

beta -Delayed gamma -Ray Spectroscopy of Heavy Neutron Rich Nuclei "South" of Lead

Relativistic projectile fragmentation of a Pb-208 primary beam has been used to produce neutron-rich nuclei with proton-holes relative to the Z = 82 shell closure, i.e., "south" of Pb. beta-delayed gamma-ray spectroscopy allows to investigate the structural properties of such nuclei with A similar to 195 -> 205. The current work presents transitions de-exciting excited states in Au-204, which are

Extending the Intermediate Data Structure (IDS) for longitudinal historical databases to include geographic data

The Intermediate Data Structure (IDS) is a standardised database structure for longitudinal historical databases. Such a common structure facilitates data sharing and comparative research. In this study, we propose an extended version of IDS, named IDS-Geo, that also includes geographic data. The geographic data that will be stored in IDS-Geo are primarily buildings and/or property units, and the

Adsorbate induced surface alloy formation investigated by near ambient pressure X-ray photoelectron spectroscopy

Formation of meta-stable surface-alloys can be used as a way to tune the binding strength of reaction intermediates and could therefore be used as improved catalyst materials for heterogeneous catalysis. Understanding the role of adsorbates on such alloy surfaces can provide new insights for engineering of more active or selective catalyst materials. Dynamical surface changes on alloy surfaces due

Ecosystem impacts of hypoxia: thresholds of hypoxia and pathways to recovery

Coastal hypoxia is increasing in the global coastal zone, where it is recognized as a major threat to biota. Managerial efforts to prevent hypoxia and achieve recovery of ecosystems already affected by hypoxia are largely based on nutrient reduction plans. However, these managerial efforts need to be informed by predictions on the thresholds of hypoxia (i.e. the oxygen levels required to conserve

Analyzing an automotive testing process with evidence-based software engineering

Context: Evidence-based software engineering (EBSE) provides a process for solving practical problems based on a rigorous research approach. The primary focus so far was on mapping and aggregating evidence through systematic reviews. Objectives: We extend existing work on evidence-based software engineering by using the EBSE process in an industrial case to help an organization to improve its auto

Sodium and potassium monolayers on Be(0001) investigated by photoemission and electronic structure calculations

Photoemission spectra show that Be(0001) surface states shift to lower energy with increasing Na or K coverage in the monolayer range. At an intermediate monolayer coverage a quantum well state appears near the Fermi edge and shifts to lower energy reaching saturation energy at full monolayer coverage. At full monolayer coverage low energy electron diffraction shows 2 X 2 order for K while Na form

Problemet är att lagarna inte efterlevs

Det kinesiska samhället har blivit alltmer baserat på lag och rätt. Men tyvärr efterlevs inte lagarna. Kommunistpartiets maktmonopol är inte enda hindret för att implementera lagar. Med i bilden finns också svaga institutioner, oklara maktbefogenheter, korruption och bristande kunskaper i rättsfrågor. Den snabba ekonomiska utvecklingen har exempelvis lett till att lokalregeringar ser mellan fingra

Biocompatibility of a polymer based on Off-Stoichiometry Thiol-Enes + Epoxy (OSTE+) for neural implants.

The flexibility of implantable neural probes has increased during the last 10 years, starting with stiff materials such as silicone to more flexible materials like polyimide. We have developed a novel polymer based on Off-Stoichiometry Thiol-Enes + Epoxy (OSTE+, consisting of a thiol, two allyls, an epoxy resin and two initiators), which is up to 100 times more flexible than polyimide. Since a fle

The same sequence variant on 9p21 associates with myocardial infarction, abdominal aortic aneurysm and intracranial aneurysm

Recently, two common sequence variants on 9p21, tagged by rs10757278-G and rs10811661-T, were reported to be associated with coronary artery disease (CAD)(1-4) and type 2 diabetes (T2D)(5-7), respectively. We proceeded to further investigate the contributions of these variants to arterial diseases and T2D. Here we report that rs10757278-G is associated with, in addition to CAD, abdominal aortic an

Radiotherapy response in head and neck cancer - evaluation of the primary tumour site

Conclusion: PET-CT scans seem to be sufficient to rule out residual tumour at the primary site. Patients with positive or equivocal PET findings should be scheduled for endoscopy with biopsy or a second PET-CT scan. Objectives: Assessment of remission at the primary site, in patients treated with organ preservation therapy with curative intent, is important to identify residual tumours requiring t

Brain natriuretic peptide is a potent vasodilator in aged human microcirculation and shows a blunted response in heart failure patients.

Brain natriuretic peptide (BNP) is normally present in low levels in the circulation, but it is elevated in parallel with the degree of congestion in heart failure subjects (CHF). BNP has natriuretic effects and is a potent vasodilator. It is suggested that BNP could be a therapeutic alternative in CHF. However, we postulated that the high levels of circulating BNP in CHF may downregulate the resp
