Using rainfall-runoff modeling to interpret lake level data

Using water balance computations, the behavior of different kinds of lakes is discussed. Simple analytical expressions relating water level to hydrological conditions and lake bathymetry are given. The importance of knowing the river basin area when analyzing lake levels is stressed. A conceptual rainfall-runoff model including lake routing is used to simulate runoff and lake levels and to compute

Investigation of the spring thermal regime in Lake Ladoga using field and satellite data

We use a combination of field and satellite data to investigate the thermal regime in Lake Ladoga in spring 1992. The analysis concentrates mainly on the temperature structure in the convectively mixed region and the dynamics of a special thermo‐hydrodynamic phenomenon called “thermal bar” (a zone of descending water with the temperature of maximum density equal to ∼4°C). A theoretical model of th

”Är det verkligen fred vi vill ha?” : Att kommunicera det komplexa fredsbegreppet genom populärmusik

Hösten 1971 släppte en ny grupp från Malmö, Hoola Bandoola Band, sitt första album, Garanterat individuell, vilket kom att få stor spridning och innebära gruppens genombrott i den svenska populärmusikgenren. En av de sånger som har kommit att göra albumet ihågkommet genom flera decennier är Fred (Till Melanie)skriven av Mikael Wiehe. Den drygt 13 minuter långa sången avslutar albumet och är av när

Fairness conceptions and self-determined mitigation ambition under the Paris Agreement : Is there a relationship?

This paper investigates the empirical relationship between countries’ expressed concerns with fairness and the ambition levels in their pledged contributions (NDCs) to the Paris Agreement, asking the following questions: 1) Are the NDCs of countries who express the most concern with fairness more or less ambitious than those of other countries? 2) Does the relationship between fairness and ambitio

Situating overtourism in urban contexts

One of the most important trends in contemporary tourism is the increase in urban tourism, both in absolute and in relative terms. In some destinations, e.g. Barcelona, the pressure from tourism on local resources such as housing and urban space has reached a point where we begin to speak about overtourism. The development of overtourism is related to decreasing relative costs of travel, e.g. low-

Influence of single-walled carbon nanotubes induced exciton dissociation improvement on hybrid organic photovoltaic devices

Torch-plasma-grown single-walled carbon nanotubes (SWCNTs) are integrated with regioregular poly(3-hexylthiophene) (P3HT) and a fullerene derivative 1-(3-methoxycarbonyl) propyl-1-phenyl[6,6]C61 (PCBM) as a hybrid photoactive layer for bulk heterojunction solar cell devices. We demonstrate that molecular information could be accurately obtained by time-of-flight secondary ion mass spectrometry thr

A Bacterial Effector Mimics a Host HSP90 Client to Undermine Immunity

The molecular chaperone HSP90 facilitates the folding of several client proteins, including innate immune receptors and protein kinases. HSP90 is an essential component of plant and animal immunity, yet pathogenic strategies that directly target the chaperone have not been described. Here, we identify the HopBF1 family of bacterial effectors as eukaryotic-specific HSP90 protein kinases. HopBF1 ado

An extraterrestrial trigger for the mid-Ordovician ice age : Dust from the breakup of the L-chondrite parent body

The breakup of the L-chondrite parent body in the asteroid belt 466 million years (Ma) ago still delivers almost a third of all meteorites falling on Earth. Our new extraterrestrial chromite and 3He data for Ordovician sediments show that the breakup took place just at the onset of a major, eustatic sea level fall previously attributed to an Ordovician ice age. Shortly after the breakup, the flux

New synthetic approaches to biofuels from lignocellulosic biomass

Lignocellulose from terrestrial plant biomass is abundant and contains polymeric carbohydrates and lignin; both recognized as attractive renewable feedstocks for energy, chemicals and materials as alternatives to fossils to meet the targets for future sustainable development. Liquid biofuels are particularly important renewable commodities because of the vast infrastructure already in place to use

Religion and domesticity

Catholics and Protestants assumed that God instituted the family and that it had certain spiritual functions to perform. In 1985, Colleen McDannell addressed changes in Christian perceptions of the home and family in nineteenth-century America. This chapter focuses on Christian ideas of the home and family in nineteenth-century Europe and touches on similar themes to those discussed by McDannell,

The regio- and stereoselective synthesis of trans-2,3-dihydropyridine n-oxides and piperidines

Reactivity N - Own: Pyridine N-oxides can be used for the complete regio- and stereoselective synthesis of trans-substituted piperidines. The sequential addition of Grignard reagents and aldehydes or ketones to pyridine N-oxides yields a complete regio- and stereoselective trans 2,3- addition reaction in high yields, and the substituted 2,3-dihydropyridine N-oxide can be reduced to form 2,3-trans-

Laboratory study of chemical speciation of mercury in lake sediment and water under aerobic and anaerobic conditions

Chemical speciation and partitioning of radiolabeled HgCl2 were studied in model aquatic systems consisting of undisturbed entrophic lake sediment and water in plastic cylinders. The cylinders were either gradually made anaerobic by a gentle flow of N2-CO2 or kept aerobic by air flow. The proportion of methylated 203Hg was significantly higher, in both water and sediment, in the anaerobic systems

Pollination by deceit, floral sex ratios and seed set in dioecious Rubus chamaemorus L.

Male and female flowers of the dioecious perennial herb Rubus chamaemorus L. are similar in general appearance. However, female flowers are somewhat smaller, do not produce any pollen, and contain very small amounts of nectar. Syrphids and bumblebees, which are important pollinators of R. chamaemorus, showed a strong preference for male flowers. Male flowers were also less often rejected by flower
