First Survey about Current Practices of Environmental Monitoring Programs within French Agri-Food Industries

Food safety is a constant challenge for stakeholders in the food industry. To manage the likelihood of microbiological contamination, food safety management systems must be robust, including food and environmental testing. Environmental monitoring programs (EMP) have emerged this last decade aiming to validate cleaning–sanitation procedures and other environmental pathogen control programs. The need to monitor production environments has become evident because of recent foodborne outbreaks. However, the boundaries of environmental monitoring are not only limited to the management of pathogens but also extend to spoilage and hygiene indicators, microorganisms, allergens, and other hygiene monitoring. Surfaces in production environments can be a source of contamination, either through ineffective cleaning and disinfection procedures or through contamination during production by flows or operators. This study analyses the current practices of 37 French agri-food industries (small, medium, or large), reporting their objectives for EMPs, microbial targets, types, numbers and frequency of sampling, analysis of results, and types of corrective actions.

Comparative Assessment of Physico-Chemical Results of Air, Water and Soil Samples Tested at Accredited and Non-accredited Laboratories

There are thousands of results produced by the environmental testing laboratory for the air, water and soil parameters. The results produced by the environmental testing laboratories are always basis of the policy decision on various occasions. The results produced by the environmental testing laboratory provide the basis for the water whether it is fit for drinking purposes or not. The soil of a particular area is fit for specific agriculture or not. Similarly, the air of a specific location is under the permissible limit of the required component or not. Over some time the environmental testing laboratories are increasing in our county and these laboratories can be segregated broadly into two categories namely accredited laboratories and non-accredited laboratories. The accreditation is done by the independent authoritative body as per the international standard ISO/IEC 17025. It is believed that the accredited laboratory has a quality management system and proven technical competence to perform a specific type of testing. This work presents the comparative studies of the physico-chemical results of air, water and soil samples tested by accredited and non-accredited laboratories. In case of soil, the pH and sulfate is tested by the accredited and non-accredited laboratories in the specific environment. Similarly, construction water and drinking water are tested for various parameters as per the relevant standard. The air samples were collected from the same site and analysis was done for the various parameters like PM2.5, PM10 and other toxic gases present in air. It is observed that there is a considerable difference between the results produced by the accredited and non-accredited laboratories. It is believed that the results produced by the accredited laboratory are more reliable in comparison to the non-accredited laboratory.

Residual Life Estimation of Humidity Sensor DHT11 Using Artificial Neural Networks

Electronic systems have become an integral part of our daily lives. From toy to radar, system is dependent on electronics. The health conditions of humidity sensor need to be monitored regularly. Temperature can be taken as a quality parameter for electronics systems, which work under variable conditions. Using various environmental testing techniques, the performance of DHT11 has been analysed. The failure of humidity sensor has been detected using accelerated life testing, and an expert system is modelled using various artificial intelligence techniques (i.e., Artificial Neural Network, Fuzzy Inference System, and Adaptive Neuro-Fuzzy Inference System). A comparison has been made between the response of actual and prediction techniques, which enable us to choose the best technique on the basis of minimum error and maximum accuracy. ANFIS is proven to be the best technique with minimum error for developing intelligent models.

A movable type bioelectronics printing technology for modular fabrication of biosensors

Biosensors have been widely used in various fields such as food industry, environmental testing and medical testing for their high sensitivity. However, current fabrication methods of biosensors, such as screen printing, micro fabrication and 3D printing suffer from complex procedures, requirement of cleanroom facility and limited fabrication materials, which significantly restrict the development and utilization of biosensors. Here, we propose a movable type bioelectronics printing method for the fabrication of biosensors by directly transferring bioelectronic materials onto various substrates using pre-fabricated molds. This simple, low-cost, yet robust method facilitates on-demand printing of master molds of partial or complete circuits on both rigid or flexible substrates. With this method, bioactive materials such as enzymes can be directly transferred onto substrates together with other electronic components, without complex modification after electrode fabrication using conventional methods. For demonstration, a dual-channel flexible electrochemical biosensor was fabricated by the movable type bioelectronics printing method for continuous monitoring of glucose and lactate. The movable type bioelectronics printing technology holds advantages of repeatability, flexibility and low cost for fabrication of biosensors on rigid and flexible substrates, as well as direct transfer printing of bioactive materials, which greatly promotes small-scale production of biosensors.

MiniCarb: A Passive, Occultation-Viewing, 6U CubeSat for Observations of CO2, CH4, and H2O

We present the final design, environmental testing, and launch history of MiniCarb, a 6U CubeSat developed through a partnership between NASA Goddard Space Flight Center and Lawrence Livermore National Laboratory. MiniCarb’s science payload, developed at Goddard, was an occultation-viewing, passive laser heterodyne radiometer for observing methane, carbon dioxide, and water vapor in Earth’s atmosphere at ~1.6 microns. MiniCarb’s satellite, developed at Livermore, implemented their CubeSat Next Generation Bus plug-and-play architecture to produce a modular platform that could be tailored to a range of science payloads. Following the launch on December 5, 2019, MiniCarb traveled to the International Space Station and was set into orbit on February 1, 2020 via Northrop Grumman’s (NG) Cygnus capsule which deployed MiniCarb with tipoff rotation of about 20 deg/sec (significantly higher than the typical rate of 3 deg/sec from prior CubeSats), from which the attitude control system was unable to recover resulting in a loss of power. In spite of this early failure, MiniCarb had many successes including rigorous environmental testing, successful deployment of its solar panels, and a successful test of the radio and communication through the Iridium network. This prior work and enticing cost (approximately $2M for the satellite and $250K for the payload) makes MiniCarb an ideal candidate for a low-cost and rapid rebuild as a single orbiter or constellation to globally observe key greenhouse gases.

Productivity of seed peas Nemchinovsky 50 in mixed crops with cereals

Abstracts. Peas is the best-known annual legume forage crop. Creation of a new variety of seed peas Nemchinovsky 50 is a breeding approach to solve the problem of vegetable protein and the production of high-quality feed with a high protein content in grain and in concentrated feed with a high content of essential amino acids (lysine, tryptophan). The analysis of long-term data showed that under various agrometeorological conditions of environmental testing, the variety was characterized by resistance to lodging and major diseases, good productivity in comparison with the previously bred variety Nemchinovsky 100. The increase in yield was facilitated by its high productivity (laying of fertile nodes), the number of seeds in a pod (4-5 pieces), the mass of 1000 seeds is at the level of 180-190 g with a protein content in the grain about 26-28%.

Preface

NOTITLE. THE MESSAGE FROM THE GENERAL CHAIRS It is our great pleasure to welcome all of you to the PHM 2021 Zhengzhou International Conference. In the past few years, this annual conference represented one of the largest gatherings of researchers and professionals to discuss most recent advancements in prognostics and system health management. This year, however, the ongoing COVID-19 pandemic and the resulting travel restrictions in many regions impose unprecedented challenges to the organization of the conference. Instead of meetings fully in person, the Conference Organization Committee has decided to shift the conference to a hybrid mode, with which some authors attended this conference in person while others participated in this conference virtually via a shared Zoom link. We hope this shift in conference mode will not affect your enthusiasm in participating in the conference and discussions. We are pleased to invite two well-known experts in the field to deliver keynote speeches at this conference: Professor Wilson Wang, Professor and University Research Chair in Intelligent Diagnostics and Prognostics of Engineering Systems, Lakehead University, Canada, and his talk is on “Fault diagnosis in gearboxes”; Dr. Yiqiang Chen, Deputy Chief Engineer of National Key Laboratory, China Electronic Product Reliability and Environmental Testing Research Institute, China, and his talk is about “Prognostic and health management technology for electric system based on PoF and data-driven method”. The conference program is also offering three paper oral presentation sessions and one poster session, arranged in the late morning and entire afternoon on October 23.
