Popular science General introduction Two main activities take place into forests: photosynthesis, or GPP (the uptake of CO2 by plants, which leads to their growth) and respiration (the release of CO2 by those plants). The Net Ecosystem Exchange NEE is the difference between photosynthesis and respiration, and it depends on the nature of the forests and on climate particularities. With the ongoing This study shows how six different European forests react during the summer to abnormally warm temperatures, from 1996 to 2006. With the forecasted increase of summer temperatures over Europe, the carbon balance of forests – photosynthesis (GPP), ecosystem respiration and Net Ecosystem Exchange - in likely to change. In this thesis, the photosynthesis and the respiration of six European forests w

I södra Kanada finns ett område med mängder av unikt välbevarade fossil från silurperioden (444-416 miljoner år sedan). I berglager från det så kallade Eramosaområdet har nu omkring 425 miljoner år gamla fossila rester efter havsborstmaskar hittats. Eftersom dessa djur består av mjuka vävnader som snabbt bryts ner efter döden så är det framför allt deras käkar, eller scolecodonter, som bevaras somThe Silurian Eramosa Lagerstätte in Ontario, Canada, is represented by three distinguished biotas (1 to 3) with exceptionally well preserved fossils. In this study, the jawed polychaete fauna is described and discussed for the first time, on the basis of scolecodonts and jaw apparatuses, recovered from Biota 1 and 3. One new paulinitid species, Kettnerites sp. a, is described from a wealthy collec

Ett första steg i arbetet att uppskatta kolflödet mellan landbaserade ekosystem och atmosfären är att så precist som möjligt analysera kvantiteten ovanjordisk biomassa. LiDAR teknologi har i detta avseende visat sig vara ett värdefullt verktyg. Det överlöpande målet med denna studie är att utveckla en förenklad metod, baserad på fjärranalys, för att uppskatta ovanjordisk biomassa för individuella As a first step in the assessment of carbon flux between the terrestrial environment and the atmosphere it is important to accurately quantify the carbon stock of forest ecosystems. LiDAR technology, in this respect, has proved to be a valuable tool, able to provide accurate estimates of aboveground biomass (AGB). The overall goal of this study was to develop a simplified method for assessing AGB

Syftet med denna uppsats var att undersöka effekterna av användningen av Facebook för organisationer med fokus på ungdomar inom socialt arbete med fokus på vad organisationsrepresentanterna har för syn på professionalitet kopplat till Facebook och även hur detta påverkar deras roll som socialarbetare och relationen till ungdomarna. Vi utförde två kvalitativa metoder. En innehållsanalys över offici”We're also on Facebook!” Organizations, that work in the social field focusing on adolescents, view on professionalism on Facebook The aim of this paper was to examine the impact of the use of Facebook for organizations focusing on adolescents within the social work. More specifically was to find out what view the organizations representatives have on professionalism when using Facebook. Als

Sverige behöver ett förbättrat konsumentkreditskydd. Fler sms-lån än någonsin har hittills i år hamnat i Kronofogdemyndighetens register som obetalda. Konsumenternas skydd är i stort sett verkningslöst, många sms-långivare missköter kreditupplysningarna och ger ut lån till människor som redan är skuldsatta. Förslag till förbättringar för konsumenternas skydd på sms-lånemarknaden finns. Nu återstår

The aim of this essay was to study how posters on the internet forum Flashback discuss social assistance and social assistance recipients. Research show that there is a tendency in today’s society to interpret the reasons for receiving social assistance as having individualistic causes. This is in spite of the fact that studies show that the individuals’ ability to provide for oneself often have s

Following rising remuneration levels, significant owner reactions to excessive executive pay, and a request for more executive accountability, there has been increased focus on disclosure of more complete information on the pay levels, program structure and performance criteria for key executives in most European markets. In general, the academic research in the area has been about the conformance

Letters of credit is an instrument of payment that is frequently used in international trade. Normally the buyer engage a bank which irrevocably promise to pay the seller when the seller (beneficiary) present a specific set of documents. The document’s purpose is to prove that the seller has fulfilled the obligation in the underlying contract of sale. The bank’s task is to investigate the document

"What should we have for dinner?" is one of the most challenging and anxiety provoking questions of today. In a society where appreciation for eating rituals and common knowledge about food have been almost lost, a new look at layout, space and functions of kitchens is needed to demystify and dedramatize the dogmatic image people have of cooking so they can rediscover the fun in the kitc

Inadequate adaption to mechanical forces, including blood pressure, contributes to development of arterial aneurysms. Recent studies have pointed to a mechanoprotective role of YAP and TAZ in vascular smooth muscle cells (SMCs). Here, we identified reduced expression of YAP1 in human aortic aneurysms. Vascular SMC–specific knockouts (KOs) of YAP/TAZ were thus generated using the integrin α8–Cre (I

Objective: The first-line approach for childhood obesity is lifestyle intervention (LI); however, success varies. This study aimed first to identify distinct subgroups of response in children living with overweight and obesity and second to elucidate predictors for subclusters. Methods: Based on the obesity patient follow-up registry the APV (Adipositas-Patienten-Verlaufsdokumentation) initiative,
