The effect of vinyl wrapping on the quality and chilling susceptibility of small-grade okra (Abelmoschus esculentus [L.] Moench.) was studied with the aim of improving storage. Pods that were stored in the air at 2-10°C rapidly dehydrated and quality decreased within two to four days. At 2°C, chilling injury was observed after four days. Pods enclosed in vinyl stored satisfactorily for ten days at 2-10°C, but on transfer to 22°C for three days deteriorated. During storage, colour intensity and firmness decreased, while a progressive increase in respiration (initially high at 2°C) indicated incipient chilling before the visual appearance of symptoms. Whereas pods were most susceptible to chilling at 2°C, the quality of those stored at 8-10°C was reduced due to fungal growth particularly during shelf life. Therefore, for best quality retention small-grade okra should be packaged and stored at 6°C.
Occupational Airborne Hazards and the Importance of Proper Respiratory Protection
Each year, the United States Occupational Safety and Health Administration (OSHA) publishes a preliminary list of the 10 most frequently cited safety and health violations for the fiscal year. It is comprised and compiled from thousands of workplace inspections conducted by federal OSHA staff from across the country. Most years, one of the top 10 cited violations involves respiratory protection. According to OSHA, an estimated 5 million workers are required to wear respirators in 1.3 million workplaces throughout...
IRSST Studies Efficacy of N95 Respirators in Conditions Representative of Human Breathing
On June 28, 2016, Institut de recherche Robert-Sauvé en santé et en sécurité du travail (IRSST) issued a press release announcing the availability of a study on “Efficiency Evaluation of N95 FFRs under Cyclic and Constant Flows.” Researchers tested the efficacy of N95 filtering facepiece respirators (FFR) in conditions of constant and cyclical air flow, simulating human breathing, from 42 to 360 liters per minute. According to the press release, N95 respirators “are...
Remote Quality monitoring in the Banana chain
A recently published paper [Remote Quality Monitoring in the Banana Chain, Jedermann et al; Philosophical Transactions A 2015; 373(issue2038)] provides a novel approach for the control of quality problems in the transportation of bananas.The authors present different models to predict the effects of the atmosphere in the storage stability of banana, as well as to evaluate the cooling efficiency, packaging and stowage in the amount of respiratory heat produced. “Quality problems occurring during or after...
Impact of barrages on downstream air entrained in water and on upstream river water quality
This research studies the effect of barrages on upstream river water quality and on its self-assimilative. Also, the impact of barrages on upstream water temperature profile is studied. The amount of entrained air in water at river downstream side as a result of barrage existence is also studied. Constructing barrages in river reaches will alter its hydraulics and thus its water quality and thermal regime. A mathematical model is developed to simulate river hydraulics, water quality parameters and temperature. A...
How PPE Makes Mining Industry Safe and Secure
Work-related health and safety has always remained a cause for concern among industry experts, managers and workers. Many industries like energy, construction, fishing and farming report high incidence of casualties. The potential hazards that miners face daily in their workplace are plenty. Many of these hazards have progressive consequences that are not realized until too late. The effects these dangers have on health are subtle and difficult to evaluate or measure. Risk and safety management principles aim to...
