Introduction: Dengue Haemorhagic Fever is an endemic disease caused by dengue virus with Aedes aegypti as the vector. Most of waste pickers in waste goods pool refuse fogging, 3M programme and abatization, so that DHF outbreak occurs in that area every year. Larva free rate also remains under the target. Therefore, it was necessary to improve DHF relation with behaviour of waste pickers. This study was used a cross sectional design.

Abstract:

Order picking (OP) is a critical yet time-consuming and labor-intensive warehouse operation within the supply chain. In picker-to-part systems with high demand, pickers are exposed to fatigue due to the excessive repetition of picking activities, which results in high human energy expenditure. The literature indicates that energy expenditure depends on the picking activity and the worker’s attributes, such as pickers’ weight, gender, and age. Studies have shown that as the weights of individuals increase, the energy consumed for the same task increases. This study proposes a two-stage stochast

Abstract:

The harvest phase plays an important role in the whole process of production of tomato fruit. Therefore, it is necessary to ensure a technological process that will not damage biological materials. The harvest phase plays an important role in the whole process. Many growers use special machines for harvesting, but there are fruits and vegetables that should be harvested manually to avoid damaging the surface or parenchyma tissue of the harvested objects. In addition to maintaining the quality of biological materials, work comfort, and ergonomic conditions for pickers should be ensured because

Abstract:

Scheduling the availability of order pickers is crucial for effective operations in a distribution facility with manual order pickers. When order-picking activities can only be performed in specific time windows, it is essential to jointly solve the order picker shift scheduling problem and the order picker planning problem of assigning and sequencing individual orders to order pickers. This requires decisions regarding the number of order pickers to schedule, shift start and end times, break times, as well as the assignment and timing of order-picking activities. We call this the order picker

As circularity is momentous, waste-picker communities all around the world are getting noticed.

Understanding these political relations is key to recognising the role of waste-pickers and making the case for justice in the circularity discourse and practices.

Abstract:

Harvesting in soft-fruit farms is labor intensive, time consuming and is severely affected by scarcity of skilled labors. Among several activities during soft-fruit harvesting, human pickers take 20–30% of overall operation time into the logistics activities. Such an unproductive time, for example, can be reduced by optimally deploying a fleet of agricultural robots and schedule them by anticipating the human activity behaviour (state) during harvesting. In this paper, we propose a framework for spatio-temporal prediction of human pickers’ activities while they are picking fruits in agricultur

Nevertheless, the domestic chores of women, gendered differences in stigmatisation, and possible societal expectations about the compatibility of waste picking with femininity do seriously hamper their work as waste pickers.

Abstract:

The spindle picker and brush-roll stripper are the two machines used to harvest cotton produced in the U.S. Adoption of each harvester type is dictated by regional differences in production environment, production practices, cultivar, and yield. The spindle picker is a selective-type harvester that harvests seed cotton only from well-opened bolls, collecting a minimal amount of undesirable foreign material with the seed cotton. The brush-roll stripper utilizes a nonselective harvesting mechanism to indiscriminately remove mature seed cotton, immature bolls, sticks, leaves, and any other vegeta

A private landowner is expected to accept a certain limitation of property rights when a vulnerable person's ability to work, and therefore right to human dignity, is in the balance.

Abstract:

Tea-picking is a highly skilled activity that is usually performed by women. This study, conducted on the Balanoor Plantations, India, from 1996 to 1998, was successful in empowering 339 women pickers and their families to take iron (60 mg of elemental iron two times a week) and vitamin A (1,600 IU) once a week, and to purchase subsidized iodized salt (30 ppm) from the plantation ration shop. The average hemoglobin level of the pickers rose significantly (p < .001) from 11.0 g/dl at baseline to 11.9 g/dl at the end of the nine months of intervention.

Intuitively, tree architecture will affect harvest efficiency of tree fruit crops, yet there are no empirical studies that document this. The objective of the current research was to investigate the role of training system on harvest rate of individual pickers in commercial sweet cherry (Prunus avium L.) orchards. We used a real-time labor monitoring system (LMS) with the ability to track and record individual picker efficiency in 11 orchards throughout the Pacific Northwest. Trees were trained to one of five different architectures: 1) upright fruiting offshoots (UFO), a planar architecture c

The control strategy of a power shift system has a significant impact on the driving stability and comfort of cotton pickers. To prevent the cotton picker from stopping to shift and reduce the jerks while shifting, in this study, the power shift system of a four-speed cotton picker was taken as the research object, and the working principles of the power shift transmission of the cotton picker and the hydrostatic transmission were analyzed. Firstly, the intelligent fuzzy control strategy of the variable pump and dual variable motor displacement of the cotton picker power shift system was desig

Abstract:

Crop characteristics of cotton are crucial to identify the important crop attributes like plant height, canopy width, sympods and monopods distribution, row spacing which affects the performance of mechanical harvesters. The activity and effectiveness of most harvest aids, including desiccants is reduced by low temperature conditions. Trash content was observed to be lesser in cotton harvested by cotton picker than cotton harvested by cotton stripper. It was found that a maximum cotton yield of 1000 kg acre-1 was obtained for a cotton plant population ranging between 45,000 and 90,000 plants a

Abstract:

Harvesting is one of the major labour intensive operations in cotton cultivation. Since cotton varieties used in our country require picking at several stages, the using of mechanical pickers is not feasible. Therefore pneumatic pickers were thought of. The dimensions of machine parameters viz. pick up pipe diameter, filter type, filter height, capacity of collection drum and speed of aspirator were varied and they were optimized through statistical analysis. The combination of 25 mm diameter pick up pipe, nylon mesh filter, 300 mm height drum were optimised. The maximum speed of aspirator i.e

One of the most significant fibre cash crops in both India and the rest of the world is cotton (Gossypium herbaceum). India is the world’s second-largest cotton producer. Cotton is hand-picked by human labours in India, which is a laborious and time-consuming task. In existing knapsack cotton picker, the cotton quality was compromised due to the impact of the impeller vanes during conveying of picked cotton to collector. Keeping all these aspects in mind, a picking mechanism for knapsack power driven cotton picker was developed with considering the agronomical parameters, functional requiremen

Abstract:

In ultrasonic testing, the time of flight (ToF) of a signal can be used to infer material and structural properties of a test item. In dispersive media, extracting the bulk wave velocity from a received signal is challenging as the waveform changes along its path of propagation. When using signal features such as the first peak or the envelope maximum, the calculated velocity changes with the propagation distance. This does not occur when picking the signal onset. Borrowing from seismology, researchers used the Akaike information criterion (AIC) picker to automatically obtain onset times. In a
