This investigation is motivated by increasing interest in diamond and composite films for applications biomedical electronic devices. A biomimetic strategy based on the use of commercial bile acids, such as ursodeoxycholic acid (UDCA) hyodeoxycholic (HDCA). Composite are developed using UDCA HDCA solubilizing agents poly(ethyl methacrylate) (PEMA) isopropanol dispersing micro- nanodiamonds. In ...

• M. scutellaris has established, dispersed, and is impacting control of P. crassipes. Wild populations are producing macropters dispersing via flight. Dispersal been documented from herbicide treated sites across terrestrial habitat. New have reached an equilibrium density that does not change with more releases. Changes to the historical flow nutrient levels freshwater bodies in Florida made ...

Fast eradication of mature biofilms is the 'holy grail' in the clinical management of device-related infections. Endogenous nitric oxide (NO) produced by macrophages plays an important role in host defense against intracellular pathogens, and NO is a promising agent in preventing biofilms formation in vitro. However, the rate of delivery of NO by various NO donors (e.g., diazeniumdiolates, S-ni...

Artificial light at night (ALAN) is gaining recognition as having an important anthropogenic impact on the environment, yet the behavioural and physiological impacts of this stressor are largely unknown. This dearth of information is particularly true for freshwater ecosystems, which are already heavily impacted by anthropogenic pressures. Atlantic salmon (Salmo salar L.) is a species of conser...

Theories on R&D organisation draw on globalisation literature as well as on communication theories. This mixed discourse is a problem, since mixing levels of logic sometimes cause faulty conclusions. How is this double logic handled in organisations, and what is the effect on R&D organisation? This study investigates R&D activities in multinational companies with several production sites and ma...

We here present an effective strategy to prepare enhanced composites using poly(vinyl alcohol) (PVA) and multiwalled carbon nanotubes (MWCNT). It contains two essential steps. First, the elaboration of homogeneous aqueous MWCNT dispersions and the selection of the most effective dispersing agent. In a sequential dispersion protocol for seven common dispersants, including surfactants and polymer...

The presence of an endogenous circadian clock in the brain of an animal was first demonstrated in the cockroach Leucophaea maderae. However, the clock's cellular basis remained elusive until pigment-dispersing hormone-immunoreactive neurons, which express the clock genes period and timeless in Drosophila, were proposed as pacemaker candidates. In several insect species, pigment-dispersing hormo...

This work describes the application of ultrasound-assisted matrix solid-phase dispersion as an extraction and sample preparation approach for aflatoxins (B1, B2, G1 and G2) and subsequent determination of them by high-performance liquid chromatography-fluorescence detection. A Box-Behnken design in combination with response surface methodology was used to determine the affecting parameters on t...

An antiserum against the crustacean neuropeptide pigment-dispersing hormone stains a small set of neurons in the optic lobes of several hemimetabolous and holometabolous insects. These cells, the primary branches of which in the optic lobe lie in the accessory medulla, fulfill several criteria predicted for neurons of the circadian clock. For example, in fruit flies they express timeless and pe...
