Purification of oxyfuel-derived CO2

Vince White, Laura Torrente-Murciano, David Sturgeon, David Chadwick
2009 Energy Procedia  
Oxyfuel combustion in a pulverised fuel coal-fired power station produces a raw CO 2 product containing contaminants such as water vapour plus oxygen, nitrogen and argon derived from the excess oxygen for combustion, impurities in the oxygen used, and any air leakage into the system. There are also acid gases present, such as SO 3 , SO 2 , HCl and NO X produced as byproducts of combustion. At GHGT8 [2] we presented reactions that gave a path-way for SO 2 to be removed as H 2 SO 4 and NO and NO

In this paper we present initial results from the Oxyfuel-UK project in which these reactions are being studied experimentally to provide the important reaction kinetic information that is so far missing from the literature. This experimental work is being carried out at Imperial College London with synthetic flue gas and then using actual flue gas via a sidestream at Doosan Babcock's 160kW coal-fired oxyfuel rig.

Data-Driven MPC for Quadrotors [article]

Guillem Torrente, Elia Kaufmann, Philipp Foehn, Davide Scaramuzza
2021 arXiv   pre-print
Aerodynamic forces render accurate high-speed trajectory tracking with quadrotors extremely challenging. These complex aerodynamic effects become a significant disturbance at high speeds, introducing large positional tracking errors, and are extremely difficult to model. To fly at high speeds, feedback control must be able to account for these aerodynamic effects in real-time. This necessitates a modelling procedure that is both accurate and efficient to evaluate. Therefore, we present an

We verify our method by extensive comparison to a state-of-the-art linear drag model in synthetic and real-world experiments at speeds of up to 14m/s and accelerations beyond 4g.

Ultrastructure of the annual cycle of female sperm storage in spermathecae of the torrent salamander,Rhyacotriton variegatus (Amphibia: Rhyacotritonidae)

David M. Sever, Cynthia K. Tait, Lowell V. Diller, Laura Burkholder
2004 Journal of morphology  
This study is the first report on the ultrastructure of the sperm storage glands (spermathecae) in the salamander Rhyacotriton variegatus. The population studied is associated with cold-water, rocky streams of the redwood (Sequoia) zone in northern California. Males possess sperm in their vasa deferentia and undergo spermiation throughout the year, but mating is seasonal. Most females with large, vitellogenic follicles (2.0 -3.9 mm mean dia.) collected from February-June contain sperm in their
more » ... permathecae, although some females with large follicles lack sperm. Other mature-size females collected during this period have small ovarian follicles (0.9 -1.2 mm mean dia.) and lack stored sperm. All females collected from September-November have small follicles (0.6 -1.6 mm mean dia.) and lack sperm, except in one instance in which a female collected in November had a small amount of degraded sperm, apparently retained from the previous breeding season. The spermathecae consist of simple tubulo-alveolar glands in which the neck tubules produce a mucoid secretory product, and the distal bulbs, where sperm are stored, contain secretory vacuoles of uniform density that stain positively for glycosaminoglycans. In specimens containing sperm, some bulbs have abundant sperm and others lack sperm, but the ultrastructure is similar in both conditions. The acini contain columnar epithelial cells with wide intercellular canaliculi, and a merocrine process releases the secretion. Spermiophagy occurs. In specimens from spring and summer with small ovarian follicles, the neck tubules are similar to those of breeding females, but the distal bulbs are reduced to cords of cells lacking a discernible lumen. Secretory activity in the distal bulbs is initiated in the fall. Spermathecae of R. variegatus are most similar to those of a stream-dwelling plethodontid, Eurycea cirrigera.

The Immune System in Duchenne Muscular Dystrophy Pathogenesis

Luana Tripodi, Chiara Villa, Davide Molinaro, Yvan Torrente, Andrea Farini
2021 Biomedicines  
Growing evidence demonstrates the crosstalk between the immune system and the skeletal muscle in inflammatory muscle diseases and dystrophic conditions such as Duchenne Muscular Dystrophy (DMD), as well as during normal muscle regeneration. The rising of inflammation and the consequent activation of the immune system are hallmarks of DMD: several efforts identified the immune cells that invade skeletal muscle as CD4+ and CD8+ T cells, Tregs, macrophages, eosinophils and natural killer T cells.
more » ... he severity of muscle injury and inflammation dictates the impairment of muscle regeneration and the successive replacement of myofibers with connective and adipose tissue. Since immune system activation was traditionally considered as a consequence of muscular wasting, we recently demonstrated a defect in central tolerance caused by thymus alteration and the presence of autoreactive T-lymphocytes in DMD. Although the study of innate and adaptive immune responses and their complex relationship in DMD attracted the interest of many researchers in the last years, the results are so far barely exhaustive and sometimes contradictory. In this review, we describe the most recent improvements in the knowledge of immune system involvement in DMD pathogenesis, leading to new opportunities from a clinical point-of-view.
