High-density polyethylene (HDPE) has a linear structure with very little or no branching and possesses a high degree of crystallinity, but it is difficult to process. Low-density polyethylene (LDPE) however has a chaotic structure with short and long branches and is easy to process. Blending of polyethylenes (PEs) is a common industrial practice. The principal reasons behind the blending of PEs...

PURPOSE To report a case of corneal melting in a patient with fornix foreshortening being treated with reformulated generic diclofenac. METHODS Case report. RESULTS An asymptomatic 76-year old man presented with central corneal melting while being treated with reformulated generic diclofenac. This formulation did not contain the vitamin E derivative, tocophersolan, which has been felt to co...

European Regulation 1169/2011 requires producers of foods that contain refined vegetable oils to label the oil types. A novel rapid and staged methodology has been developed for the first time to identify common oil species in oil blends. The qualitative method consists of a combination of a Fourier Transform Infrared (FTIR) spectroscopy to profile the oils and fatty acid chromatographic analys...

Blending different low molecular weight gelators (LMWGs) provides a convenient route to tune the properties of a gel and incorporate functionalities such as fluorescence. Blending a series of gelators having a common bis-urea motif, and functionalised with different amino acid-derived end-groups and differing length alkylene spacers is reported. Fluorescent gelators incorporating 1- and 2-pyren...

We present the case of a young male that suffered from fungal corneal abscess and corneal melting. The patient was treated successfully by corneal cross-linking. Taking into account our experience from this case, we offer to consider corneal cross-linking as a therapeutic option in cases of fungal keratitis.

The work presents a comprehensive profile of the physicochemical characteristics opoka sedimentary rock in context its use as hybrid filler for thermoplastics. Determining functional parameters studied was main aim this research. Thermal treatment leads to changes morphology and phase composition. A wide range techniques used, such low-temperature nitrogen adsorption, FT-IR, TGA, XRD, optical, ...

The geochemical variations of Kilauea's historical summit lavas (1790^1982) document a rapid fluctuation in the mantle source and melting history of this volcano. These lavas span nearly the entire known range of source composition for Kilauea in only 200 yr and record a factor of V2 change in the degree of partial melting. In this study, we use high-precision measurements of the U-series isoto...

This study demonstrates the capabilities of NIR imaging as an effective tool for characterization of pharmaceutical powder blends. The powder system used in this small-scale powder blending study consists of acetaminophen (APAP, the model API), microcrystalline cellulose (MCC) and lactose monohydrate. Mixtures of these components were blended for different times for a total of ten time points (...

Commercial ecological gasoline is being obtained by blending multiple components. Increasing a refinery’s economic performance depends, among other things, on obtaining optimum blending recipes for the available components. To determine the optimum blending recipe, knowing the mathematical blending model for blending properties estimation and a linear optimization algorithm are necessary. As a ...
