In the Drosophila leg, activation of Notch leads to the establishment of the joints that subdivide the appendage into segments. We find that mutations in bowl result in similar phenotypes to Notch, causing fusion and truncations of tarsal segments (tarsomeres) and, like its close relative Odd-skipped, Bowl is produced in response to Notch signalling at a subset of segment boundaries. However, d...

reactivity controlled compression ignition (rcci) is a novel combustion concept which uses port fuel injection (pfi) of a low reactivity fuel and direct injection (di) of a high reactivity fuel with optimum multiple injection to provide a stratified mixture inside the combustion chamber. piston bowl design has a considerable effect on engine’s pollutant emissions specially unburned hydrocarbons...

Cucumber fruits (Cucumis sativus L., cv. Trópico F1) grown on perlite substrate and NFT (Nutrient Film Technique) were harvested during two seasons (winter and spring) to monitor the effects of climatic conditions and hydroponic growth systems on fruit quality at harvest. The best fruit quality at harvest, as measured by lightness and hue angle parameters, was obtained during the 3 weeks follow...

In order to achieve fully automated picking of camellia fruit and overcome the technical difficulties current machinery such as inefficient service manual auxiliary picking, a novel multi-links-based machine was proposed in this paper. The working principle process device analyzed. mechanism kinematics equation given, velocity executive body obtained, well acceleration. acceleration at pivotal ...

OBJECTIVE A 3-bowl system is used for washing-up eating utensils on many expeditions when running water is not available. The utensils are washed in the first bowl until they are visibly clean, rinsed in the second bowl, and disinfected in the third bowl. The objective of this study was to evaluate the efficacy of this system in reducing bacterial loads on contaminated utensils and to compare i...

Date is the most popular fruit in middle-east countries. However, the date production process is accompanied by a substantial increase of loss during picking, storage, commercialization and conditioning process. Date and their byproducts have many essential elements for the growth of microorganisms. Thus, they can be converted into valueadded compounds through biotechnology. In this paper, date...

Thirty-six F1 hybrids were generated from nine lines and four testers through line x tester mating design, these F1’s along with 13 parents 1 commercial check (Punjab-8) evaluated to study the magnitude direction of heterosis for growth earliness over various characters in okra. Heterosis was studied compare traits such as days 50% flowering, picking, plant height, number internodes, branches p...

In the era of Industry 4.0, digital agriculture is developing very rapidly and has achieved considerable results. Nowadays, agriculture-based research more focused on use robotic fruit picking technology, main direction such topics algorithms for computer vision. However, when vision successfully locate target object, it still necessary to arm movement reach object at physical level, but path p...

Cellulase, polygalacturonase (PG), pectinmethylesterase (PME), respiration, and ethylene production were determined in single "Fuerte" avocado fruits from the day of harvest through the start of fruit breakdown. PME declined from its maximum value at the time of picking to a low level early in the climacteric. PG activity was not detectable in the preclimacteric stage, increased during the clim...

For manipulators to be an effective option in soft automation, they require redundancy and versatility. A typical application is motion in unpredictable surroundings such as foliage navigation in automated fruit picking. To date, centralized control architectures with real-time constraints have proven undesirable for the control of redundant systems. This paper uses a modular decentralized tech...
