Nutmeg (Myristica fragrans Houtt.) is an important tree spice which produces two different spices. Harvesting should be done at proper stage of maturity in order to maintain their nutrients level as attaining desirable quality. Presently, the method adopted for harvesting nutmeg in Konkan region is done manually. The DBSKKV, Dapoli has developed four different fruit harvesters. The present study was undertaken to evaluate the field performance and check feasibility for harvesting of matured Nutmeg fruits with DBSKKV, Dapoli developed fruit harvesters. The performance of the DBSKKV developed fruit harvesters for matured Nutmeg fruit were evaluated in terms of harvesting capacity (kg/h), damage fruit per cent, total harvesting time (h), labour requirement and economics of Nutmeg harvesting. The average harvesting capacity of Naveen Mango harvester, Nutan Mango harvester, Atul Sapota harvester and Multi fruit harvester foe matured Nutmeg harvesting was found to be 51.33 Nos./h (2.79 kg/h), 61 Nos./h (2.78 kg/h), 51.33 Nos./h (2.92 kg/h) and 144.66 nos./h (5.63 kg/h) respectively. The average damage fruit per cent for Naveen Mango harvester, Nutan Mango harvester, Atul Sapota harvester and Multi fruit harvester for matured                      Nutmeg harvesting were found to be 25.73%, 25.79%, 17.02% and 7.76% respectively. The cost of operation of Naveen Mango harvester, Nutan Mango harvester, Atul Saopta harvester and Multi fruit harvester for matured Nutmeg harvesting was found to be Rs 18.21/kg, Rs 18.44/kg, Rs 17.53/kg and Rs 9.01/kg respectively. Among the evaluated DBSKKV, Dapoli fruit harvesters for matured Nutmeg harvesting, Multi fruit harvester perform better with minimum damage of fruits.

Results: In DPPH free radical scavenging assessment, free radicals neutralization expressed as % of inhibition 49.69±0.06% also by IC50 values as 68.43 µg/ml surmise middle level of antioxidant property. The total phenolic content expressed as 186.25 mg/g equivalent of gallic acid indicates, active phenolic content. Oral administration of 200 and 400 mg/kg of extract dose and reference drug vildagliptin (50 mg/kg) for the duration of the 4-day study period, and initiated % of inhibition the blood glucose level measured as 22.48%, 44.78% and 62.02% regard as the significant anti-hyperglycemic properties. The analgesic activity was investigated by using the acetic acid-induced writhing test in mice, at the dose of 200 mg/kg body and 400mg/kg weight, and resulting 50.4% and 68.10% correspondingly, which was considerably significant with a standard drug. Conclusion: The present study suggests that methanolic extract of seed and mace of Myristica fragrans Houtt can manage moderate oxidative stress as well as perform the painkilling action.

In order to improve the process management of table grape packaging, its performance should be evaluated. However, the literature on performance evaluation indicators is scarce. To address this research gap, we propose a method for the development of performance evaluation indicators for table grape packaging units, which are characterized by labor-intensive and highly seasonal production processes in the agro-economic sector. The stages include the following: contextualizing table grape packaging units, selecting the performance objectives, selecting techniques to be used in the development of the indicators, and applying the method to the packaging units of table grapes. The techniques adopted in the development of the indicators aimed at the cost, quality, flexibility, reliability, and speed performance objectives were data envelopment analysis, principal component analysis, quantification of the batch, compliance with the program within the established deadline, and measurement of the execution time of the batch, respectively. The results obtained in the case study demonstrate that the correlations between the performance indicators do not indicate the need to disregard any of them. Furthermore, the standard deviation values for each indicator are similar. Thus, both results of correlations and standard deviation confirm the importance of the indicators chosen for the performance evaluation of table grape packaging.

Abstract. We present a generic algorithm for numbering and then efficiently iterating over the data values attached to an extruded mesh. An extruded mesh is formed by replicating an existing mesh, assumed to be unstructured, to form layers of prismatic cells. Applications of extruded meshes include, but are not limited to, the representation of three-dimensional high aspect ratio domains employed by geophysical finite element simulations. These meshes are structured in the extruded direction. The algorithm presented here exploits this structure to avoid the performance penalty traditionally associated with unstructured meshes. We evaluate the implementation of this algorithm in the Firedrake finite element system on a range of low compute intensity operations which constitute worst cases for data layout performance exploration. The experiments show that having structure along the extruded direction enables the cost of the indirect data accesses to be amortized after 10–20 layers as long as the underlying mesh is well ordered. We characterize the resulting spatial and temporal reuse in a representative set of both continuous-Galerkin and discontinuous-Galerkin discretizations. On meshes with realistic numbers of layers the performance achieved is between 70 and 90 % of a theoretical hardware-specific limit.

Harvesting is one of the major labor intensive works in rice cultivation. Appropriate harvesting machinery is urgently needed to reduce labor and production costs. Production cost of rice becomes high due to labor shortage and high wage rate during harvesting time. Techno-economic performance of Korean self-propelled reaper (KR), China self-propelled reaper (CR) and BRRI reaper (BR) were evaluated in order to identify the field constrains and problems of the reapers at Mithapukur of Rangpur, Bangladesh during Aman season of 2013. The actual field capacities of the KR, CR and BR were found 0.18, 0.17 and 0.15 ha h–1with the corresponding field efficiency of 55, 68 and 56%, respectively. The variation of field capacity among the models was due to turning time losses, weight of the reaper and operator’s skill. The fuel consumption of the reapers was 4.11, 2.61 and 8.39 l ha–1 for KR, CR and BR, respectively. The shattering loss of paddy harvesting was 1.66, 1.50 and 1.45% for KR, CR and BR, respectively. The break-even area of the reapers was 9.15, 7.82 and 8.43 ha yr-1 for KR, CR and BR, respectively. It is evident that the reaper could be used successfully as labor saving and user friendly technology to eliminate post-harvest problems in Bangladesh.J. Bangladesh Agril.
