In the present study, we applied extrusion-cooking to polished rice flour so as prepare gluten-free pasta. The aim of work was investigate effect feed moisture (28, 30 and 32%) screw speed (60, 80 100 rpm) on selected pasta quality attributes (water absorption, cooking loss, firmness, stickiness microstructure) extrusion response (specific mechanical energy). Our results showed that significant...

OBJECTIVES To investigate the effects of height, surface firmness, and visual reference on standing balance in construction workers. DESIGN Controlled laboratory study with balanced repeated measures. PARTICIPANTS Twenty four construction workers. SETTING Test subjects performed standing tasks at ground level as well as at 3 m and 9 m high balconies on firm or deformable surfaces with clo...

Factor XIII (F XIII) is an essential parameter for final clot stability. The purpose of this study was to determine the impact of the addition of factor (F)XIII on clot stability as assessed by Rotation Thromboelastometry (ROTEM®). In 90 intensive care patients ROTEM® measurements were performed after in vitro addition of F XIII 0.32 IU, 0.63 IU, 1.25 IU and compared to diluent controls (DC; aq...

Microbicides are being actively researched and developed as woman-initiated means to prevent HIV transmission during unprotected coitus. Along with safety and efficacy, assessing and improving compliance is a major area of research in microbicide development. We have developed carrageenan-based semisoft vaginal suppositories and have previously evaluated how physical properties such as firmness...

Shelf life estimation is an important factor to predict the freshness of fruits. This study aimed investigate shelf and changes in physicochemical properties three different pineapple varieties, namely MD2, Josapine, Morris stored at 5, 10, 25 °C. The effect storage temperature on total soluble solids, pH, moisture content, firmness, colour was evaluated for 21 days period. It revealed that tem...

A relatively new, non-destructive, method for the assessment of optimal blueberry fruit maturity directly on plant uses a DA-meter (delta absorbance) to measure chlorophyll absorbance (IAD). Here, ‘Aurora’ quality parameters (peel color, firmness), chemical composition (individual sugars, organic acids and phenolics) relative expression anthocyanidin synthase (ANS) genes were examined at four d...

The onset of climacteric is associated with the end of melon fruit shelf-life. The aim of this research was to develop practical and applicable models of fruit ripening changes (hardness, moisture loss) also able to discriminate between climacteric and non-climacteric behaviour. The decrease in firmness was measured non-destructively by flat-plate compression; moisture loss was measured by weig...

Previous literature suggests that haptic gas pedals can assist the driver in search of maximum fuel economy. This study investigated three haptic pedal designs, each with high and low intensities of feedback, in a rapid prototyping, paired comparison design. Twenty drivers took part, experiencing the systems in a high-fidelity driving simulator. Results suggested that drivers were best guided t...
