In the recent years, increasing labour cost and shortage of being major constraints to follow manual harvesting in cotton staggered manner. Further, it is very expensive farmers would like increasingly opt for mechanical harvesting. this context, suggested that research should focus reduce cultivation substantially by promoting use synchronized maturity defoliants encourage agriculture, are use...

Studies on harvesting robots with manipulator were started with the tomato fruit harvesting robot since 30 years ago by Prof. Kawamura, Kyoto University [1]. The robot consisted of a 5 DOF manipulator, a harvesting end-effector, a color TV camera which was used for stereo vision, and a battery car for traveling in the ridges as shown in Figure 1. Following the harvesting robot, the robotic tech...

original article   health, safety, and environment management are dedicated a vast area in which ergonomics aspects known as one of the related aspects. in the following case study, the occupational hygiene by ergonomic intervention is focused. one of the prevalent activities among industrial sectors' workers in the developing countries is manual lifting tasks and other related physical activit...

purpose: to report the outcomes of manual lamellar keratoplasty (lkp) in patients with delayed-onset mustard gas keratitis (mgk) and compare visual outcomes between subgroups with simultaneous or sequential klal and lkp. methods: in this retrospective, interventional study, 52 eyes of 37 male survivors of chemical warfare with mgk who underwent lkp were included. the results were evaluated with...

background: the nature of work in the construction industry is closely associated with many human factor hazards. manual construction workers are exposed to hand-arm vibration, repetitive movements, holding of heavy loads and tools, and frequent manual materials handling hazards in their daily tasks. work related musculoskeletal disorders are major problems faced by construction workers, which ...

The purpose of this study was to evaluate the impact of introduction a new work tool on health and productivity of manual harvesting sugarcane workers. In this study it was performed aErgonomic Work Analysis (EWA) to analyze the work tool changes.The study included sugarcane workers, drivers, fiscals, and technical's safety at work.During the analysis process, 134 questionnaires were applied,ai...

Policy decisions in governmental models are often based on their perception and acceptance in the general public. Traditional methods for harvesting opinions like telephone or street surveys are time intensive and costly and direct interaction between a governmental member and the population is limited. Social media harbor the chance to easily get a high number of opinions and proposals in form...

When exposed to excess light illumination photosynthetic organisms switch into a photoprotective quenched state where the excess energy is safely dissipated as heat. When these processes are investigated by means of ultrafast spectroscopy, the experimentalist is faced with the unnatural process of singlet–singlet annihilation which often makes the interpretation of the results very complicated....

The light-harvesting antenna of photosystem II (PSII) has the ability to switch rapidly between a state of efficient light use and one in which excess excitation energy is harmlessly dissipated as heat, a process known as qE. We investigated the single-molecule fluorescence intermittency of the main component of the PSII antenna (LHCII) under conditions that mimic efficient use of light or qE, ...

Single-molecule spectroscopy was employed to elucidate the fluorescence spectral heterogeneity and dynamics of individual, immobilized trimeric complexes of the main light-harvesting complex of plants in solution near room temperature. Rapid reversible spectral shifts between various emitting states, each of which was quasi-stable for seconds to tens of seconds, were observed for a fraction of ...
