   Sammanfattning : Statistical experimental designs have been used for method development and optimisation of separation. Two reversed phase HPLC methods were optimised. LÄS MER

3. 2. Enantiomeric separation by capillary electrophoresis : With special emphasis on the partial filling technique

   Författare :Ahmad Amini; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; Farmaceutisk kemi; Pharmaceutical chemistry; Farmaceutisk kemi; analytisk farmaceutisk kemi; Analytical Pharmaceutical Chemistry;

   Sammanfattning : Capillary electrophoresis as a powerful separation technique was employed for resolution of racemic drugs. Taurodeoxycholate (TDC), different cyclodextrins and α1- acid glycoprotein (AGP) were dissolved in the background electrolyte at low pH (3.0 to 4.0 ) as chiral selectors. LÄS MER

   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CO2 separation; Ionic liquids; Deep eutectic solvents; Cosolvent; Thermodynamic modeling; Process simulation and evaluation; Energiteknik; Energy Engineering;

   Sammanfattning : CO2 separation plays a vital role in reducing CO2 emissions to combat climate change, in which solvent-based absorption is widely considered the most promising technology. Many conventional chemical and physical solvents have been introduced for CO2 separation, still facing challenges. LÄS MER

5. 4. Separation of Pharmaceuticals by Capillary Electrophoresis using Partial Filling and Multiple-injections

   Författare :Henrik Lodén; Curt Pettersson; Torbjörn Arvidsson; Ahmad Amini; Morgan Stefansson; Uppsala universitet; []
   Nyckelord :Capillary Coating; Chiral Separation; Enantiomers; Mass-spectrometric Detection; Method Validation; Multiple-injection Capillary Zone Electrophoresis; Non-aqueous Capillary Electrophoresis; Organic Solvents; Pharmaceutical Analysis; Quantitative Analysis;

   Sammanfattning : Different multiple-injection methodologies and the partial filling technique (PFT) have been utilized for separation of pharmaceuticals by capillary elec-trophoresis. In multiple-injection capillary zone electrophoresis (MICZE), the samples and all standards, used for construction of the calibration curve, are analyzed within a single run. LÄS MER

7. 5. Partial Response and Faster-than-Nyquist Signaling

   Författare :Fredrik Rusek; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication engineering; Signalbehandling; Signal processing; Partial Response Signaling; Faster-than-Nyquist Signaling; Digital Communications; Coding Theory; Telekommunikationsteknik;

   Sammanfattning : Bandwidth efficiency is a key objective in the design of a digital communication system. Traditionally it is accomplished by increasing the constellation size of the signaling system. In this thesis alternative techniques are studied. Because the communication channel is continuous, so must the actual time signals be. LÄS MER
