Effects of flow regime on the young stages of salmonid fishes. Summary and conclusions based on results for 1981-1985 [PDF]

open access: yes, 1985
The main British salmonid species spawn in clean gravel in streams and rivers, many of them in the upland areas of Britain. The earliest stages of the life cycle (eggs and alevins) spend some months within the gravel of the river bed.

Composite membranes comprising of polymeric and molecular amines embedded in poly(vinyl alcohol) matrices to facilitate CO2/H2 separation

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Polymeric and molecular amines embedded in hygroscopic matrices to facilitate CO2 transport for CO2/H2 separation. Abstract This work dealt with composite membranes comprising of polyvinylamine (PVAm) and triethylenetetramine (TETA) embedded in poly(vinyl alcohol) (PVA) for CO2/H2 separation via facilitated transport of CO2, where polymeric and ...

Laboratory study of the effect of the number of groin in the radial arrangement of permeable groin on the maximum scouring rate of the nose [PDF]

open access: yesمهندسی و مدیریت ساخت, 2023
The scouring phenomenon is one of the issues that are always important in the design of various types of hydraulic structures; among these structures is the groin. These structures prevent their erosion by diverting the flow from the river bank. The flow

Iron(III)‐loaded cation exchange resin: A dual approach for aqueous H2S removal and biogas desulphurization

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Left: Desulphurization method application. Right: Novel desulphurization method. Abstract The presence of hydrogen sulphide (H2S) in biogas poses significant environmental and operational challenges due to its corrosive and toxic properties. Thus, this study aimed to develop a dual‐function desulphurization system using a cation exchange resin (CIER ...
