Copepod Feeding Strategy Determines Response To Seawater Viscosity: Videography Study Of Two Calanoid Copepod Species, Abigail Tyrell

SoMAS Research Data

Calanoid copepods, depending on feeding strategy, have different behavioral and biological controls on their movements, thereby responding differently to environmental conditions such as changes in seawater viscosity. To understand how copepod responses to environmental conditions are mediated through physical, physiological, and/or behavioral pathways, we used high-speed microvideography to compare two copepod species, Acartia hudsonica and Parvocalanus crassirostris, under different temperature, viscosity, and dietary conditions. Acartia hudsonica exhibited “sink and wait” feeding behavior and typically responded to changes in seawater viscosity; increased seawater viscosity reduced particle-capture behavior and decreased the size of the feeding current. In contrast, P. crassirostris continuously …

Deactivation And Regeneration Study Of A Co-Promoted Moo3 Catalyst In Hydrogenolysis Of Dibenzofuran, Jie Zhang, Chuang Li, Weixiang Guan, Xiaozhen Chen, Xiao Chen, Chi Wing Tsang, Changhai Liang

Faculty of Science & Technology (THEi)

The efficient hydrogenolysis of dibenzofuran (DBF) was investigated at 360 °C and atmospheric hydrogen pressure with Co/MoO3 catalysts. All catalysts selectively cleaved the C-O bond and thus effectively transformed DBF to biphenyl (BP) at relatively moderate conditions. A strong promotional effect in the catalytic activity was observed over the Co/MoO3 catalyst with the optimal Co content of 3 wt %, as evidenced by the decreasing activation barrier which was resulted from Co-facilitated increase of active Mo species and acidic sites. The best catalytic activity was realized with almost 100% yield of BP over Co/MoO3. During 300 h of catalyst life …

Diseases With Skin And Lung Involvement: Pulmonologist's Perspective, Vishnu Moleyar, Anupama Noojibail

Open Access archive

A variety of conditions/diseases can involve skin and lungs together. Knowledge about these conditions and the skin and respiratory manifestations in these conditions will lead to early diagnosis and proper management. Some of the dermatological manifestations may be very classical where the diagnosis will be obvious at a glance. Many a times, dermatological manifestations may narrow the differential diagnoses. In some cases, dermatological manifestations may indicate the severity/stage of the disease and prognosis. In some diseases with dermatological manifestations, where no obvious respiratory symptoms or signs are evident, screening for the underlying lung disease may be indicated. Some dermatological manifestations …
