Design and implementation of a microcontroller based flammable gas detector and automatic alarm system to ensure the industrial and domestic safety

Author: 
Navid Bin Ahmed, Kazi Naziba Tahsin, Shahriar Khan, Mahbubul Hoq and Didarul Alam
Abstract: 

The risk of industrial and domestic accidents from methane gas leakage can be minimized by an inexpensively designed gas detector. This approach intends to produce a suitable and reliable solution in the context of a third world country, where equipment and components are either not available or prohibitively expensive. This affordable and easy-to-install device monitors and displays the concentration of gas mixed in the air and sounds a buzzer just before the concentration reaches danger level. It is often required to know the amount of gases mixed in the air for which the optimum and safe amount of oxygen can be available in that area. This system is a reliable solution as a safety tool in modern industrial and residential settings. It consists of an Atmel Atmega 328P microcontroller, an MQ-9 gas sensor, a buzzer for automatic alarm system, a red LED for warning and an LCD monitor for display the concentration of gas. The system is user friendly and fit to be installed in kitchens, labs or industries.

Abstract: 

In Côte d'Ivoire, stakes in food security are enormous for rice. The present study, which discusses about effect of rice mycorrhization, is a contribution to ricebiological fertilization. Study compared incidence of intake of a mycorrhizal inoculant "AGTIV" to mineral fertilization, on soil, growth and development parameters of upland rice, in the West part of Côte d’Ivoire. In order to assess the efficiency of these two fertilization methods, an unfertilized control treatment was integrated in the experimental device, a Fisher Block with six repetitions. Results obtained show that the rice plant lends itself well to mycorrhizal symbiosis with Glomus intraradices fungus. This symbiotic association has contributed to the maintenance of the soil structure and favored the transport of mineral nutrients, especially phosphorus to the rice plant. This significantly improved tillering (147.5 tillers/m²) and yield (1.62 t ha-1) of rice. The yields are better as mycorrhizae are combined with mineral fertilizers (2.36 tha-1), for a gain of 64%. It is therefore not excluded, in the presence of mycorrhizal fungi, to bring fertilizers (organic or mineral) to rice, since the soil is not an inexhaustible resource of nutrients. In short, mycorrhization appears to be a powerful biological tool for optimizing sustainable soil management and rice yields.

Author: 
Moumouni Derra, Dr. Ousmane I. Cisse, Dr. Luc T. Bambara, Karim Kabore and Pr. François Zougmoré
Abstract: 

The aim of this work was to assess the heavy metal environmental pollution in Ouagadougou and its suburban, in order to evaluate the risks on the population health. Lettuce samples, tap and surface waters sample were analyzed to determine the total heavy metal content. The Inductive Coupled Plasma-Spectrometry was used to analyze the samples. The concentration of Cr and Ni at Boulbi were 37.94ppm and 11.00ppm respectively and 8.19ppm of Pb in Baskuy sample. The Cr concentration in Boulbi lettuce was very high than the toxicity thresholds fixed by WHO and concentration of Ni was within the toxicity rang fixed by WHO. The higher value of Pb can lead to health risk due to the bioaccumulation effect. The concentration of Al, Ba, Cu, Fe, As and Cr were low et less than the standards set by WHO. In addition, Massili water was more polluted than Loumbila dam water. Massili water contains Co which is not found in Loumbila dam water. In addition, the concentration of Fe and Mn in water exceeded the recommended standards for irrigation water. The results of this study showthe presence of heavy metals in water and lettuce, andthe degree of risk of consumer.
