2. 1. Waste in road transport operations - using information sharing to increase efficiency

   Author : Henrik Sternberg; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; road transport operations; transport efficiency; ICT; information sharing; transport information systems; freight transportation; motor carrier;

   Abstract : In terms of efficiency, road transport operations have historically seen very little development relative to other supply chain areas and some authors have even referred to freight transportation as the “forgotten factor.” Several studies world-wide have shown a generally low level of efficiency in road transport operations. The U.S. READ MORE

4. 2. In vitro and in silico prediction of drug-drug interactions with transport proteins

   Author : Gustav Ahlin; Per Artursson; Christel Bergström; Johan Karlsson; Jörg König; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Solute carrier; SLC transporter; OCT1; Organic cation transporter 1; SLC22A1; OATP1B1; SLCO1B1; Organic anion transporting peptide 1B1; Drug transport; Active transport; Genetic polymorphism; Cell lines; Gene expression; Multivariate data analysis; OPLS; Pharmaceutics; Galenisk farmaci; Biopharmacy; Biofarmaci; galenisk farmaci; Pharmaceutics; Biopharmaceutics; biofarmaci;

   Abstract : Drug transport across cells and cell membranes in the human body is crucial for the pharmacological effect of drugs. Active transport governed by transport proteins plays an important role in this process. A vast number of transport proteins with a wide tissue distribution have been identified during the last 15 years. READ MORE

5. 3. Impact of carrier localization on recombination in InGaN quantum wells with nonbasal crystallographic orientations

   Author : Ruslan Ivanov; Saulius Marcinkevičius; Nicolas Grandjean; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; InGaN; quantum well; semipolar; nonpolar; near-field microscopy; carrier localization; carrier transport; optical polarization; Fysik; Physics;

   Abstract : The modern InGaN technology demonstrates high efficiencies only in the blue spectral region and low current operation modes. The growth of InGaN quantum wells (QWs) on nonbasal crystallographic planes (NBP) has potential to deliver high-power blue and green light emitting diodes and lasers. READ MORE

6. 4. Valley-Polarized Charge Transport in Diamond

   Author : Nattakarn Suntornwipat; Jan Isberg; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CVD diamond; valleytronics; Negative Differential Mobility; NDM; electron polarization; Time-of-Flight; ToF; magnetotransport; carrier transport; drift velocity; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

   Abstract : Diamond is a wide bandgap semiconductor with extreme properties such as high thermal conductivity, high breakdown field and high carrier mobilities. These properties together with the possibility to synthesize high purity Single-Crystalline (SC) diamond by Chemical Vapor Deposition (CVD), makes it a really interesting material for electronic devices.

7. 5. Establishing the mechanistic basis of sugar transport

   Author : Abdul Aziz Qureshi; David Drew; Magnus Wolf-Watz; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; membrane transport; transport energetics; nucleotide-sugar transporters; glucose transporters; malaria; cancer; Biochemistry; biokemi;

   Abstract : Sugar is a vital molecule required for cell viability and homeostasis. Sugar is important for metabolic energy, energy storage, signaling, structure and osmolyte regulation. Transport of sugar represents an important physiological process. READ MORE
