The physical and mechanical properties of foods are important, if not essential, in the design of suitable systems, machines, and structures for planting, harvesting, handling and processing of agro-products. Phaseolus vulgaris L. is a popular legume species that play an important role in human diet and among easily available sources of plant protein. However, despite its important roles, there is a lack of information on the physical and mechanical properties of common beans cultivated in Tanzania. The objective of this study was therefore focused on experimental determination of physical and mechanical properties for Uyole-96, Kablanketi, and Wanja, common beans cultivars grown in the Southern Highlands of Tanzania. Experimental results showed that the average length, width, and thickness were 19.96 mm, 8.97 mm, and 7.6 mm at a moisture content of 17.15% dry basis (db.), 13.92% db., and 14.64% db. for Uyole-96, Kablanketi, and Wanja, respectively. The results further show that the average mean diameters (Da) were 10.93, 9.35, and 9.55 mm for Uyole-96, Kablanketi, and Wanja, respectively. The geometric mean diameters (Dg) were 9.66, 8.35, and 8.80 mm for Uyole-96, Kablanketi, and Wanja, respectively, whereas sphericity was found to be 53, 64, and 58% for the same types of beans. Repose angle measuremnts were experimentally determined as 40, 36, and 35 degrees for Uyole-96, Kablanketi, and Wanja, respectively. Weight for apparent density analysis was 709.27, 686.30, and 766.10 kg/m3 for Uyole-96, Kablanketi, and Wanja, respectively, whereas the apparent densities were determined as 1142, 1158, and 1327 kg/m3, respectively, for the same types of beans. Results from the study showed that physical and mechanical properties for Uyole-96, Kablanketi, and Wanja differ significantly from other common beans cultivars cultivated in other countries. Data on physical and mechanical properties determined in this study establishes a convenient reference table for the mechanization and processing of Tanzanian common beans cultivars .

Physical And Mechanical Characteristics

Abstract Peanut is one of the most important oil crops in Turkey and grown mainly in Adana, Osmaniye and Aydın provinces. Five peanut cultivars (NC-V11, Halisbey, Arioglu 2003, Sultan and Osmaniye 2005), mostly grown in Turkey, were analyzed for the physical and mechanical characteristics of pods to select the most promising candidate. The average length, width, thickness, the geometric mean diameter, sphericity index and rupture force were studied. The results indicated that all the studied traits were varied significant among the varieties. Thus, a significant extent of genetic diversity was observed among the peanut cultivars under study. Shelling percentage values were varied between 65.7 - 71.6%. The highest shelling percentage was obtained at NC-V11 variety, while the lowest value was obtained at Sultan. The variety NC-V11, Halisbey, Arioglu 2003, Sultan and Osmaniye 2005 showed the average lengths of 42.27, 44.68, 46.17, 49.39 and 44.57 mm; width of 16.00, 17.90, 17.57, 17.45, and 17.92 mm; thickness of 17.33; 18.68; 18.54, 18.42, and 19.10 mm, respectively. Rupture force and stiffness values of peanuts depend on the cultivars and varied from 191.06 to 253.19 N and 129715.61 to 184954.67 N/m as higher and lower values, respectively. The varieties Arioglu 2003, Halisbey and Sultan have lower rupture force and stiffness values. On the other hand, NC-V-11 and Osmaniye-2005 varieties have higher value of rupture force and stiffness. These findings indicated that these two varieties need to more energy for hull rupture. But, in the same time, it played an important role for storage. The NC-V-11 variety achieved the highest values of rupture force than others. Some varieties had thick and strong hull, while some other had thin and weak.

Some physical such as length, width, thickness, mass, geometric mean diameter, sphericity and surface area and mechanical properties such as deformation at cracking, cracking force, energy absorbed and hardness of nuts and kernels were determined at three orientations first time for two walnut cultivars, namely Mara?-18 and Yalova-1 widely grown in Turkey. For nuts, the average length (45.48 mm), mass (12.70 g), geometric mean diameter (36.83 mm) and surface area (42.66 cm2) were the highest in cv. Yalova-1 while width (34.18 mm), thickness (33.74 mm), shell thickness (1.48 mm) and sphericity (87.41%) were the highest in cv. Mara?-18. For all the loading orientations, the values of deformation at cracking, cracking force, energy absorbed and hardness of cv. Mara?-18 were higher than those of cv. Yalova-1. The effect of loading orientation to kernel extraction quality was found insignificant for both walnut cultivars.

Studying the physical and mechanical properties of agricultural products has been the subject of criticism and discussion for many years already and has attracted the attention of many researchers. The physical and mechanical properties of agriculture products are the most important parameters in the design of agricultural machinery sorting systems, transmissions, processing and packaging systems. The potato is one of the most important agricultural products as a food resource. The aim of this research is to investigate the physical properties and mechanical behaviour of the potato due to its importance and the current inadequate information about it. In this research, some of the physical and mechanical properties of the potato were measured in standard conditions. The length, width, thickness, geometric mean diameter and arithmetical diameter, sphericity, surface area, aspect ratio, mass, volume, bulk density and the  projected mean area were included in the physical properties. The mechanical properties of the potato were determined by using a universal testing machine (MRT-5; Santam, Germany) with a uniaxial compression test. Then, the mechanical properties were measured with four repetitions. The physical properties of the potato such as length, width, thickness, mass, volume and geometric mean diameter had a direct relationship, while the density had an inverse relation to the size. The result of the mechanical properties of the sample, such as vertical stress, elasticity module, deformation energy, fracture force and deformation were obtained respectively as 0.34 MPa, 3.09 MPa, 892.02 J, 8.80 N and 207.22 mm. The comparison of the potato’s real volume with the standard shapes showed that the potato’s shape is similar to an oval due to the largest determination coefficient (R<sup>2</sup> = 0.86). The results of this research can be used for the design and optimisation of the processing equipment, as well as the transporting, sorting and packing of the potato crop.

The beetle Astylus variegatus (Germ.) (Coleoptera: Melyridae) is frequently found in flowers feeding on pollen. Responses of A. variegatus to volatile floral attractants were studied in common beans (Phaseolus vulgaris L.) fields. Traps originally designed to capture Diabrotica speciosa (Germ.) (Coleoptera: Chrysomelidae), consisted of plastic bottles (2 L) with 150 holes (5-mm diameter) yellow gold painted and containing inside a plastic strip (3.5 <FONT FACE=Symbol>´</FONT> 25 cm) with Lagenaria vulgaris (L.) powder (0.28% B cucurbitacin - feeding stimulant and arrestant for diabroticites) sprayed with carbaril insecticide. Treatments consisted of 1,4-dimethoxybenzene (one or two dispensers per trap), 1,4-dimethoxybenze + indole, 1,4-dimethoxybenzene + cinnameldehyde and control. Volatile average release rates (over ten days) was approximately 32 mg day-1 per dispenser under laboratory conditions. 1,4-dimethoxybenzene-lured traps caught significantly more beetles than the control, three and seven days after trap setting. Ten days after the onset of the experiment, there were no differences in number of beetles caught by treatments. Captures were higher in the 1,4-dimethoxybenzene + cinnamaldehyde treatment than in 1,4-dimethoxybenzene only in the first assessment. Adding indole to 1,4-dimethoxybenzene did not improve beetle captures.
