Now available on Fast Track: Fabricating nano-sized BiVO4/InVO4/g-C3N4 photocatalysts for efficient degradation of Acid Blue 92 azo dye

Posted on 15. June, 2018.

Photocatalysis using semiconductors has received considerable interest in both the scientific and engineering areas. Especially, metal oxide semiconductor photocatalysts have been widely studied for environmental applications such as cleaning of air and the removal of hazardous compounds from wastewater. Metal vanadates are a notable category of inorganic nanomaterials that have received attention due to their wide applications and many researchers has been interested in the synthesis of metal vanadates of manganese, iron, etc.

Science Progress invites world authorities to contribute review articles on the most interesting, important and meaningful scientific topics, and publishes occasional issues on specific themes. Contributions should aid significantly the understanding of any area of science including climate/environmental change, geochemistry, biochemistry, biology, technology, cosmology, physics, chemistry, mathematics, psychology, medicine and health.

Effects of supplemental food on the behaviour and paternity status of male Indigo Buntings (Passerina cyanea)

Posted on 11. June, 2018.

Breeding is energetically costly and, if energy-limited, birds may alter their time budgets, spending less time engaged in some activities and more time in others. Investigators who have provided breeding birds with supplemental food have noted changes in time budgets, but the extent and types of changes have been found to vary among species.

Relationship between morphology and trophic ecology in an assemblage of passerine birds in riparian forests of the Paraná River (Argentina)

Posted on 4. June, 2018.

We describe the ecomorphology of an assemblage of bird species found in riparian forests of the Middle Paraná River, Argentina. We sought to determine (1) the more important morphological characteristics that separate coexisting species, (2) whether such separation was related to the trophic ecology of each species and (3) whether a priori guilds showed morphological similarity.

Now available on Fast Track: Investigation of reaction mechanisms and kinetics of the radical scavenging ability of 5-tert-butylbenzene-1,2,3-triol and 3,5-di-tert-butylbenzene-1,2-diol compounds towards OOH radical

Posted on 31. May, 2018.

Reactive oxygen species (ROS) is a collective term used by biologists to refer to oxygen-centred radicals, such as the superoxide (O2) and hydroxyl radical (OH•), as well as some non-radical derivatives of O2, such as hydrogen peroxide (H2O2), singlet oxygen (1O2) and hypohalites [e.g. hypochlorous acid (HOCl)] Organic derivatives of oxygen species such as alkoxyl radicals (RO•) and peroxyl radicals (ROO•) are also important examples of ROS which can seriously alter cell structures such as lipids, proteins and DNA. Thus, this phenomenon is strongly implicated in the natural aging process: cardiovascular disorder, neurodegenerative, diabetes, Alzheimer’s disease and cancer.

Effect of variation in nestling hunger levels on the begging behaviour of nestlings and the provisioning behaviour of adult American Kestrels

Posted on 28. May, 2018.

Little is known about how variation in nestling begging intensity influences the behaviour of adult raptors and how responses of adult males and females to such variation might differ. Our objective was to manipulate the begging intensity of nestling American Kestrels (Falco sparverius) and examine the responses of adults.

The impact of the female immune challenge on parental feeding rate, mass and body condition index of offspring

Posted on 21. May, 2018.

Reproduction is a resource-demanding period, when trade-offs between investment in immunity versus other functions of an adult organism may exist. This research investigates the potential trade-off between a challenged immune system of a female parent and parental provisioning in free-living Great Tits Parus major and Eurasian Blue Tits Cyanistes caeruleus
