Anthropogenic increase of nitrogen (N) deposition has threatened forest ecosystem health at both regional and global scales. In N-limited ecosystems, atmospheric N input is regarded as an important nutrient source for plant growth. However, it remains an open question on how elevated N deposition affects plant growth in N-rich forest ecosystems. To address this question, we used a simulated N deposition experiment in an N-rich mature tropical forest of southern China, with N addition levels as 0kgNha(-1)yr(-1) (Control), 50kgNha(-1)yr(-1) (Low-N), 100kgNha(-1)yr(-1) (Middle-N) and 150kgNha(-1)yr(-1) (High-N), respectively...

Understanding sorption and desorption processes is essential to predicting the mobility of radionuclides in the environment. We investigate adsorption/desorption of cesium in both binary (Cs+one mineral) and ternary (Cs+two minerals) experiments to study component additivity and sorption reversibility over long time periods (500days). Binary Cs sorption experiments were performed with illite, montmorillonite, and kaolinite in a 5mM NaCl/0.7mM NaHCO3 solution (pH8) and Cs concentration range of 10(-3) to 10(-11)M...

Mood disorder patients frequently experience difficulty making decisions and may make sub-optimal decisions with adverse life consequences. However, patients' styles for decision-making when ill and after treatment have received little study to date. We assessed healthy controls (HC, n = 69) and patients with major depressive disorder (MDD, n = 61) or bipolar disorder (BP, n = 26) in a current major depressive episode using the Melbourne Decision-making Questionnaire. A subset of participants was re-evaluated after completing six weeks of pharmacotherapy...

In recent years, behavior-related endpoints have been proposed as rapid and reliable ecotoxicological tools for risk assessment. In particular, the use of detritivores to test the toxicity of pollutants through feeding is currently becoming a well-known method. Experiments combining feeding with other behavioral endpoints can provide relevant information about direct and indirect toxicological effects of chemicals. We carried out a feeding experiment with the shredder Gammarus pulex in order to detect indirect (through leaf conditioning) and direct effects (through water exposure) of two pollutants at environmentally relevant concentrations: the fungicide prochloraz (6 μg/L) and the antidepressant fluoxetine (100 ng/L)...

Concussed individuals have been found to experience balance deficits in the anterior-posterior (AP) direction as indicated by greater Center of Pressure (COP) displacement and velocity. One possible reason for this change in balance control could be due to damage to the lateral vestibulospinal tract which sends signals to control posterior muscles, specifically ankle extensors leading to compensatory torques about the ankle. The purpose of the study was to quantify balance assessments in individuals experiencing persistent post-concussion symptoms (PCS) to determine balance control changes following a vestibular training intervention...

Phytochemical investigation of Idesia polycarpa (Salicaceae) resulted in the structure elucidation of nine previously undescribed phenolic natural products along with six known compounds. The compounds are structurally related to salicinoids that are known defense compounds from Salix and Populus species. The I. polycarpa diet was toxic, as shown in feeding experiments with larvae of Lymantria dispar, an herbivorous broadleaf tree generalist insect, and with larvae of Cerura vinula, a specialist adapted to poplar...

Thoa T Nguyen, Steffen J Glaser
A general approach is introduced to optimize experiments for the analysis of spin systems in the presence of chemical exchange. Rather than optimizing individual pulse sequence elements, such as refocusing pulses, entire relaxation dispersion sequences are optimized in the form of a single shaped pulse. This is achieved by defining a performance index that is only based on the remaining signal after the relaxation dispersion sequence for a range of exchange, relaxation, offset, and rf inhomogeneity parameters...

BACKGROUND: While it is well documented that many experience harm from others' substance use, little is known about the psychological strain associated with others' use. The aims were: (1) to describe the prevalence of worries about others' alcohol, cigarette and illegal drug use, (2) whose substance use people worry about, (3) the overlap in worries, and (4) to examine how worries about others' use of each substance vary according to demographics, own substance use and experience of harm from others' use...

An experiment was conducted to investigate the spatial memory and transformation of spatial relations in a sample of 7-, 9-, and 11-year-olds and to compare their performance with that of adults. Four pictures of animals were presented at different locations on the outline of a circle. Participants were instructed to memorize the array of locations and then, in a direct retrieval task, to reconstruct it from memory on a piece of paper that included only the circle outline. Then, in the transformation task, participants were asked to randomly place one of the animals at a new position around the circle and then to place the remaining three animals so that object-to-object locations were preserved...

Two experiments explored preschoolers' social preferences and moral judgments of prosocial and antisocial others. In Experiment 1, 3- to 5-year-olds (N=74) observed helping and hindering scenarios previously used to explore sociomoral evaluation in preverbal infants. Whereas 3-year-olds in Experiment 1 did not reliably distinguish between the helper and hinderer when reporting social preferences or moral judgments, both 4- and 5-year-olds preferred the helper, judged the helper to be "nicer" than the hinderer, selectively allocated punishment to the hinderer, and were able to justify their punishment allocations...
