  1. 21. Continuous-Time Delta-Sigma Modulators for Ultra-Low-Power Radios

    Författare :Dejan Radjen; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Delta-Sigma; continuous-time; analog-to-digital; ultra-low-power; clock jitter; single operational amplifier; SAR quantizer;

    Sammanfattning : The modern small devices of today require cheap low power radio frequency (RF) transceivers that can provide reliable connectivity at all times. In an RF transceiver, the analog-to-digital converter (ADC) is one of the most important parts and it is also one of the main power consumers. LÄS MER

  3. 22. Hypoxia and auto resuscitation in the neonatal rodent with special reference to the sympatho-adrenal system

    Författare :Shi-Zeng Yuan; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :adrenal medulla; apnea; asphyxia; autoresuscitation; catecholamines; SIDS;

    Sammanfattning : Preterm infants exhibit irregular breathing with frequent episodes of apnea, which may be associated with cyanosis and bradycardia. Perinatal asphyxia causes a considerable amount of morbidity and mortality that occurs during early life. Studies of mechanisms responsible for perinatal asphyxia are therefore very important.

  4. 23. Clinical presentation and outcomes of COVID-19 compared with other respiratory virus infections and hospital populations

    Författare :Pontus Hedberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : As of September 2022, more than 600 million cases of coronavirus disease 2019 (COVID-19) and 6.5 million deaths have been officially reported to the World Health Organization (WHO). The unfolding pandemic has exerted enormous strains on healthcare systems worldwide yet to be fully understood. LÄS MER

  5. 24. Flexible cables for massive-parallel high-speed data communications

    Författare :Allan Huynh; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The demand for high-speed data communications has pushed both the wired and wireless technologies to operate at higher and higher frequencies. Classic Kirchhoffs voltage and current laws cannot be directly applied, when entering the microwave spectrum for frequency > 1 GHz. Instead, the transmission line theory should be used. LÄS MER

  7. 25. Pharmaceutical compounds; a new challenge for wastewater treatment plants

    Författare :Maja Dlugolecka; Elzbieta Plaza; Bengt Hultman; Nicklas Paxéus; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; activated sludge; biodegradation; granular activated carbon GAC ; membrane bioreactor MBR ; pharmaceutical compounds; wastewater; Water engineering; Vattenteknik;

    Sammanfattning : Analytical analyses conducted at the Himmerfjärden WWTP (285.000 PE connected) identified 70 pharmaceutical compounds belonging to different therapeutic classes. Such organic micropollutants at low detected concentration range of µg - ng l-1 did not affect the treatment processes at WWTP. LÄS MER
