“…The glass gave the least amount of friction due to its smooth and polished surface. Similar results have been reported for sweet corn (Cos ßkun, Yalc ßın, & Ö zarslan, 2006); cactus pears (Kabas, Ozmerzi, & Akinci, 2006); plum cultivars (Ertekin, Gozlekci, Kabas, Sonmez, & Akinci, 2006); faba beans (Altuntas ß & Yıldız, 2007); neem nuts (Visvanathan, Palanisamy, Gothandapani, & Sreenarayanan, 1996); and raw cashew nuts (Balasubramanian, 2001).…”

“…Positive linear relationships between the bulk density and the moisture content have also been reported by Paksoy and Aydın (2004) for edible squash seed, by Çalışır and Aydın (2004) for cherry laurel, and by Kabas et al (2006) for cactus pear. …”

Altuntas E., Erkol M. (2010): Physical properties of shelled and kernel walnuts as affected by the moisture content. Czech J. Food Sci., 28: 547-556.The variations in physical properties such as the size dimensions, unit mass, sphericity, projected area, bulk density, true density, volume, coefficient of friction on various surfaces, and terminal velocity of shelled and kernel walnuts as a function of the moisture content were determined. With an increase in the moisture content, the sphericity, projected area, bulk density, volume, and porosity of shelled and kernel walnuts increased, whereas the true density linearly decreased. Studies on rewetted walnuts showed that the terminal velocity increased from 14.17 m/s to 15.50 m/s, and from 12.60 m/s to 14.35 m/s, for shelled and kernel walnuts, respectively. The static and dynamic coefficients of friction of shelled and kernel walnuts on chipboard and plywood surfaces also increased linearly with an increase in the moisture content.

“…Figure 3a, b, and c shows dimensions of onion, namely length, width and thickness; PA, PB, and PC are the projected areas taken along these three mutual perpendicular axes. Mass (g) of individual onion was determined by using an electronic balance with an accuracy of 0.01 g. Actual volume was measured by the water displacement method (Mohsenin 1986;Kabas et al 2005;Karababa 2006). The bulk density was determined using the mass-volume relationship by filling an empty plastic container of predetermined volume and weight, the onion were placed inside the container from a constant height, and weight (Fraser et al 1978).…”

Ghabel R., Rajabipour A., Ghasemi-Varnamkhasti M., Oveisi M., 2010. Modeling the mass of Iranian export onion (Allium cepa L.) varieties using some physical characteristics. Res. Agr. Eng., 56: 33-40.Mass modeling can be used for development of post-harvest equipment related to onion (Allium cepa L.) processing such as grading, packing and food production processes. There are instances in which it is desirable to determine relationships among crop physical characteristics. In this study, the mass of Iranian export onion varieties (Azarshahr and Sefide Qom) was predicted by using different physical characteristics applying linear models with three different classifications: (1) -single or multiple variable regressions of onion dimensional characteristics, (2) -single or multiple variable regressions of onion projected areas, (3) -estimating onion mass based on measured (actual) volume and volumes of assumed shapes (prolate spheroid and ellipsoid). The results showed that mass modeling of onion based on length and three projected areas are the most appropriate models in the first and second classification, respectively. In third classification, the highest determination coefficient was obtained for mass modeling based on the actual volume as R 2 = 0.99 whereas corresponding values were 0.96 for both assumed onion shapes (prolate spheroid and ellipsoid), respectively. In economical and agronomical point of view, suitable grading system of onion mass was obtained based on length as nonlinear relation M = 0.035a 2 -1.64a + 36.137, R 2 = 0.96.
