2. 1. Theoretical Modeling of Enzyme Catalysis with Focus on Radical Chemistry

   Author : Vladimir Pelmenschikov; Per E. M. Siegbahn; Tim Clark; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; density functional theory; enzyme catalysis; radical chemistry; zinc-containing peptidase; methyl-coenzyme M reductase; ribonucleotide reductase; superoxide dismutase; Quantum chemistry; Kvantkemi;

   Abstract : Hybrid density functional theory (DFT) B3LYP method is applied to study the four diverse enzyme systems: zinc-containing peptidases (thermolysin and stromelysin), methyl-coenzyme M reductase, ribonucleotide reductases (classes I and III), and superoxide dismutases (Cu,Zn- and Ni-dependent enzymes). Powerfull tools of modern quantum chemistry are used to address the questions of biological pathways at their molecular level, proposing a novel mechanism for methane production by methyl-coenzyme M reductase and providing additional insights into hydrolysis by zinc peptidases, substrate conversion by ribonucleotide reductases, and biological superoxide dismutation.

4. 2. Modelling ice surface elevation changes in Dronning Maud Land, East Antarctica : Bridging the gap between in-situ and numerical model reconstructions

   Author : Martim Mas e Braga; Arjen P. Stroeven; Irina Rogozhina; Jonathan M. Harbor; Clas Hättestrand; Frank Pattyn; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; ice sheet modelling; glaciology; paleoglaciology; naturgeografi; Physical Geography;

   Abstract : Ice sheets are an active component of Earth's climate system. Their topography influences atmospheric circulation and changes in their volume alters freshwater fluxes to the oceans, affecting ocean water masses, atmospheric carbon uptake, and global sea level. READ MORE

5. 3. Women's Access to Land in Tanzania : The Case of the Makete District

   Author : Kerbina Moyo; Peter Ekback; Walter de Vries; Jenny Paulsson; E. August Rosnes; Alexandra Weitkamp; Jesper M. Paasch; KTH; []
   Keywords : access to land; women; property rights; customary law; customary land tenure; Real Estate and Construction Management; Fastigheter och byggande;

   Abstract : Access to land is crucial for combating discrimination. Women who are denied such access tend to be disadvantaged, a pattern that results in economic powerlessness. Tanzana is among the most undeveloped nations in the world, where gender inequalities with respect to accessing land are central problems. READ MORE

6. 4. Host-pathogen interactions during tick-borne flavivirus infection : pathogenesis, tropism and tools

   Author : Ebba Rosendal; Anna K. Överby Wernstedt; Emma Nilsson; Jonathan D. Gilthorpe; Sonja M. Best; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Tick-borne encephalitis virus; Langat virus; pathogenesis; type I interferons; central nervous system; neuroinflammation; structural proteins; Infectious Diseases; infektionssjukdomar; mikrobiologi; Microbiology;

   Abstract : Tick-borne encephalitis virus (TBEV) is a neurotropic member of the genus Flavivirus. It may transmit to humans through the bite of an infected tick or consumption of unpasteurized dairyproducts, and causes tick-borne encephalitis (TBE). TBE constitutes a significant health burden in Eurasia, with more than 10,000 cases reported every year. READ MORE

7. 5. Corporate Disclosures Regulations : Social Solution or a Problem?

   Author : Asif M Huq; Kenneth Carling; Fredrik Hartwig; Arend Hintze; Moti Zwilling; Högskolan Dalarna; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; audit choice; audit regulations; corporate governance; corporate sustainability; EU-wide accounting reforms; firm growth; greenhouse gas emissions; machine learning; microdata analysis; natural learning processing; new institutional economics; nonfinancial reporting; survey;

   Abstract : Regulations are argued to have the answer to solving various social and economic problems that society faces today (e.g., climate change, tax evasion, etc.). READ MORE
