Light Microscopic and Histochemical insights in the kidneys of Aseel birds
A study was conducted to find out normal histology and histochemistry in kidneys of Aseel birds. The cortical areas were larger and lobulated, though it was challenging to differentiate the lobes due to minimal intralobular connective tissue. The medullary areas appeared as small cones, with the apex facing the uteric bud and those oriented toward the cortex. Both the cortex and medulla were encapsulated containing abundant collagen fibers. The components of the cortical regions were compactly arranged, whereas the medullary components were loosely arranged. Renal corpuscles, including juxtamedullary and cortical renal corpuscles, were observed. The juxtamedullary corpuscles were larger and located in the cortical regions near to the medulla, while the cortical renal corpuscles were smaller, loopless, and appeared toward the periphery of the cortex. Central veins were observed, surrounded by proximal convoluted tubules (PCT) and distal convoluted tubules (DCT), creating a lobular pattern similar to that of the liver. The cortical tubules, medullary tubules, and the capsules of both cortex and medulla showed a positive reaction to the combined PAS-Alcian blue stain. The cortical capsule was moderately positive for acid Phosphatase and exhibited a strong reaction to alkaline phosphatase. The brush border and basement membrane of PCT displayed a moderate reaction to both acid and alkaline phosphatases. The DCTs were moderately positive for both enzymes. Additionally, the medullary capsule showed a moderate reaction to acid phosphatase and a strong reaction to alkaline phosphatase. The thin and thick segments of the medullary collecting ducts exhibited moderate reactions to both acid and alkaline phosphatases.
Eco-friendly Technology for the Management of Root-knot Nematode Meloidogyne incognita Infesting Noni (Morinda citrifolia L.) Plantation Under Field Conditions
Root-knot nematode Meloidogyne incognita (RKN), a key pest infecting noni (Morinda citrifolia) plantations cultivated as intercrop in coconut gardens in coastal states of India. One alternative to using nematicides to protect the affected crop is to plant marigold (Tegetes erecta) as an antagonistic crop to suppress nematode populations in infested soil. Therefore, field experiments were conducted with marigold seedlings planted in different numbers at noni tree basins to reduce RKN and minimize the plant mortality. The result indicated planting six marigold plants around the Noni tree basin from June to December suppressed the M. incognita population up to 89.7% with a significant increase in the number of branches (175%) and yield (264.6%) over control, indicating efficacy in managing the nematodes and also showing better plant vigor in coconut gardens. Moreover, the mortality rate of noni plants decreased from 22.07% to 3.9. The present finding confirms that planting of marigold plants around noni plant basins plays a significant role in the management of M. incognita infesting noni plantations cultivated intercropped in coconut gardens. These results would have the potential to develop comprehensive integrated plant parasitic nematode management strategies.
Evaluation of Real-Time Target Path Adjustment in Autonomous Driving Performance for an Agricultural Autonomous Platform
This study developed and evaluated the performance of an autonomous driving system that enhances the work efficiency and precision in orchard work. The autonomous driving system includes a main controller equipped with an RTK-GPS and IMU, automatic steering wheel, interface box, and a one-touch switch. The experimental conditions included a one and two-stage variable driving test where the path-position deviation was altered to 10, 20, and 30 cm on both a standard paved road and test orchard field at a tractor speed of 2 km/h. On the test orchard field, adjusting the work path to 10 cm and 20 cm resulted in a positional error of approximately 2 cm between the initial adjustment and the return to the original driving path. For a 30 cm adjustment in the work path, position errors were noted at 10 cm for both the initial change and return, with heading angle errors of 4 degrees; however, the vehicle exhibited stable driving on the autonomous path after re-entering the initial path.
A Novel Optimization Design Method of Picking Robot Based on MBSE and Lean Thinking
Aiming at the problems of low efficiency and poor accuracy of the existing picking robot, this paper proposes a novel optimization design method based on MBES and lean thinking. Firstly, the optimization analysis is accomplished by deeply excavating the potential lean factors in robot design requirements. Then the functional architecture is established by operational analysis and system analysis. Based on the analysis results, the lean optimization design of the robot is studied. Specifically, by constructing the value flow of the picking process, the picking manipulator is optimized from a fully flexible arm to a rigid-flexible hybrid structure. Furthermore, in order to reduce the waste of time in the picking process, the DMAIC method is used to optimize the action of the picking equipment on both sides to operate separately, so as to improve the picking efficiency.
Impact of different spatial geometries of Gmelina arborea on performance of lentil varieties in Bundelkhand region
Gmelina arborea-based agroforestry provides farmers with increased economic benefits, improves soil health, helps counteract the decline in national forest cover, and offers raw materials for both industrial use and local community needs. The study examined three different spacings of Gmelina arborea: 5 m × 5 m, 5 m × 4 m, and 5 m × 3 m, under two growing conditions: sole cropping and intercropping. Data analysis revealed that lentil varieties grown in open conditions exhibited better growth and yield attributes than those grown in agroforestry. The analysis of various growth and yield characteristics indicated that growing environment significantly affected plant growth and yield attributes. Specifically, parameters such as plant height (37.76 cm), number of primary branches (5.34), root nodules per plant at 90 days after sowing (1.23), dry matter accumulation (9.43), days to physiological maturity (124.43), days to 50% flowering (77.1), pods per plant (87.6), straw yield (1732 kg ha-1), grain yield (1014 kg ha-1), and biological yield (2746 kg ha-1) were all higher in sole cropping as compared to agroforestry. IPL 316 lentil variety performed better compared to L 4727 in both cropping systems. Overall, Gmelina arborea-based agroforestry yielded greater economic returns than sole cropping.
