2. 1. Drivers of carbon sink function in tropical seagrass beds : influence of carbon import, plant composition, seascape configuration and human activities

   Author : Rashid O. Ismail; Mats Björk; Martin Gullström; Maria E. Asplund; Amelia S. Buriyo; Matern S.P. Mtolera; Teresa Alcoverro; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon sequestration; tropical seagrass meadows; coastal seascape; landscape configuration and transformation; calcification; allochthonous carbon; community respiration; carbon sink; human disturbance; coastal conservation; Plant Physiology; växtfysiologi;

   Abstract : Seagrass meadows are effective carbon sinks, sequestering atmospheric CO2 and capturing allochthonous organic material, storing organic carbon (Corg) in their sediments, so called Blue Carbon. In tropical areas, seagrass meadows have a high number of calcareous organisms, which can offset carbon sequestration by releasing CO2 through their calcification. READ MORE

4. 2. Studies on the enantioselective disposition of amlodipine : A challenge in bioanalysis

   Author : Martin Josefsson; Martin Ahnoff; Linköpings universitet; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : To study the disposition of the enantiomers of the calcium channel blocker amlodipine in human plasma, an enantioselective high performance liquid chromatographic (HPLC) assay was developed. Several HPLC techniques such as chiral ion-pair forming, chiral derivatisation and direct separation on chiral columns were evaluated. READ MORE

5. 3. Climate in the eastern Mediterranean during the Holocene and beyond – A Peloponnesian perspective

   Author : Martin Finné; Karin Holmgren; Hanna S. Sundqvist; Georgia Destouni; Neil Roberts; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Stable isotopes; U-Th dating; stalagmites; climate variability; flooding history; eastern Mediterranean; southern Greece; Holocene; Pleistocene; Physical Geography; naturgeografi;

   Abstract : This thesis contributes increased knowledge about climate variability during the late Quaternary in the eastern Mediterranean. Results from a paleoclimate review reveal that regional wetter conditions from 6000 to 5400 years BP were replaced by a less wet period from 5400 to 4600 years BP and to fully arid conditions around 4600 years BP.

6. 4. Striping on flexo post-printed corrugated board

   Author : Martin Holmvall; Tetsu Uesaka; Joseph S Aspler; Mittuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik; Chemical engineering; Kemiteknik;

   Abstract : Striping is the most common print non-uniformity on corrugated board. It is defined as periodic print density and/or print gloss variations parallel to the flutes. Corrugated boards are mainly printed with flexography, making striping a major concern for the flexographic post-printing industry. READ MORE

7. 5. Electro-Acoustic and Electronic Applications Utilizing Thin Film Aluminium Nitride

   Author : David Michael Martin; J. Olsson; I. Katardjiev; S. Gevorgian; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AlN; FBAR; FPAR; CMP; SOI; Nickel Silicide; Wafer Bonding; Electronics; Elektronik; Elektronik; Electronics;

   Abstract : In recent years there has been a huge increase in the growth of communication systems such as mobile phones, wireless local area networks (WLAN), satellite navigation and various other forms of wireless data communication that have made analogue frequency control a key issue. The increase in frequency spectrum crowding and the increase of frequency into microwave region, along with the need for minimisation and capacity improvement, has shown the need for the development of high performance, miniature, on-chip filters operating in the low to medium GHz frequency range.
