In modern agriculture, the energy that is consumed in every stage of production can be divided in direct (e.g. fuels and lubricants) and indirect (e.g. machinery embodied energy, materials and agrochemicals etc). This energy consumption can be examined further in environmental level as environmental impact. Environmental impact regards to the CO2 that is emitted during the production process an...

Bifunctional hairy silica nanoparticles (BHSNs), which are silica nanoparticles covered with alkyl and amino organic chains, were prepared as high-performance additives for lubricants. Compared with hairy silica nanoparticles covered by a single type of organic chain, binary hairy silica nanoparticles exhibit the advantages of both types of organic chains, which exhibit excellent compatibility ...

Preliminary note The occurrence of working irregularities in journal bearing such as loss of geometry correctness, sudden failure of lubrication, overloading, etc., requires that serious damage of journal bearings have to be overcome in a short period of time. In such cases, it is important that the applied combinations of materials and lubricants do not have a tendency to seizure. Such critica...

PURPOSE To describe a case of severe rosacea with ocular involvement. CASE REPORT A 28-year-old female patient presented with extensive facial and ocular eruptions. She had a history of treatment with oral prednisolone due to the clinical diagnosis of lupus erythematosus (LE), which had resulted in transient improvement of the lesions, but was followed by exacerbation of the lesions. With the...

The translational diffusion of a fluorescent dye embedded at a dilute concentration in a confined fluid was compared at rest and during shear. The fluid, octamethylcyclotetrasiloxane (OMCTS), was confined between step-free muscovite mica to thickness 3-4 layers. Fluorescence correlation spectroscopy showed that the time scales of intensity-intensity autocorrelation functions were essentially th...

I would love a microbicide gel. But right now, even cheap water-based lubes are simply NOT available in many settings. So what would be the case with a specially formulated gel? Of course, something to consider is that in some of our countries, something that “promotes homosexuality” like a rectal microbicide for anal sex, God forbid, might be banned before it is even actually produced! But, th...
