“…The angles of repose of mahogany seed and kernel were determined using an open ended box made of plywood 150 × 150 × 150 mm in size with a removable front panel and following the method described by Aviara et al (1999).…”

“…The inclined plane method (Aviara et al 2005a,b) was commonly used by investigators in studying the coefficient of friction of agricultural products on different structural surfaces. Dutta et al (1988a) and Aviara et al (1999) used a specially constructed box with removable front panel to determine the angle of repose of gram and guna seeds. The commonly used method of determining the specific heat of agricultural products was the method of mixtures (Dutta et al 1988b;Yang et al 2002).…”

Aviara N.A., Lawal A.A., Mshelia H.M., Musa D., 2014. Effect of moisture content on some engineering properties of mahogany (Khaya senegalensis) seed and kernel. Res. Agr. Eng., 60: 30-36.Some engineering properties of mahogany seed and kernel were investigated and expressed as a function of moisture content. In the moisture ranges of 7.1-32% and 5.3-22% (d.b.), respectively, the seed and kernel length, width and thickness increased with increase in moisture content. One thousand seed and kernel weight increased linearly with moisture content. True density, bulk density, porosity and angle of repose of seed and kernel also increased with increase in moisture content. Static and kinetic coefficients of friction increased linearly with moisture content and varied with structural surfaces. Specific heat increased with increase in both moisture content and temperature. Regression equations were used to express the relationships existing between the engineering properties and seed and kernel moisture contents.

“…The roundness and sphericity values were calculated according to Alibas and Koksal (2012). The aspect ratio (R) and surface area (A) of the seed was calculated according to Avira et al (1999) and Abdullah et al (2011).…”

A b s t r a c t. The aim of the present study was to determine various physical, mechanical, and structural characteristics of seed of pepper cultivars Yağlık Kapya, Demre Sivri, Yalova Carliston, Kandil Dolma, and Cin Sus Yediveren, which are grown extensively in Turkey, with initial moisture content ranging between 7.03 and 7.21% (w.b.). Width, length, and thickness were found to be in the range of 3.00-3.72, 3.43-4.40, and 0.66-0.82 mm, respectively. It was revealed that sphericity of the seeds of Yağlık Kapya, Demre Sivri, Yalova Carliston, Kandil Dolma, and Cin Sus Yediveren were 51, 57, 56, 51 and 57%, respectively. In terms of the roundness which ranges between 76 and 85% depending on pepper cultivars. The aspect ratio of Yağlık Kapya, Demre Sivri, Yalova Carliston, Kandil Dolma, and Cin Sus Yediveren were determined to be 84.60, 88.04, 94.43, 85.55, and 87.67%, respectively. It was also noted that the porosity of the pepper seeds was in the range of 44.94-49.61%. Besides, we found that as the weight of pepper seeds increased, their terminal velocity increased accordingly, and thus terminal velocities were found to be 2.87-4.66 m s -1 . In the current study, the static friction angle and coefficients of the cultivars were determined by means of six different plates including aluminium, stainless steel, galvanized iron, rubber, glass, and plywood. The plywood plate was found to be the least slippery; consequently, the static friction angle and coefficient were determined to be the highest for the plywood plate.

“…Shape and diameter of cocoa bean were measured by Micrometer screw gauge with 0.01mm accuracy (Stainless Steel Electronic LCD Digital Vernier Caliper Gauge Micrometer 0-6" Range) (Bart-Plange and Baryeh, 2003) (Fig.1). Ten seeds randomly selected from 10 subsamples consisting of 100 seeds were measured and the mean values were analysed (Singh and Goswani, 1996;Aviara et al, 1999). …”

“…The experiments were randomly repeated (5 x 100 random seeds) and mean values were calculated (Deshpande et al, 1993;Srinath et al, 1996, Aviara et al, 1999. The final values were divided by 100 to acquire the bean mass.…”
