Phosphate solubilizers enhance NPK fertilizer use efficiency in rice and legume cultivation

It has been reported that phosphate solubilizing bacteria (PSB) are the most promising bacteria among the plant growth promoting rhizobacteria (PGPR); which may be used as biofertilizers for plant growth and nutrient use efficiency. Moreover, these soil micro-organisms play a significant role in regulating the dynamics of organic matter decomposition and the availability of plant nutrients such as nitrogen (N), phosphorus (P), potassium (K) and other nutrients. Through this study, the management of nutrient use efficiency by the application of PSB was targeted in order to make the applied nutrients more available to the plants in the rice (Oryza sativa) and yardlong bean (Vigna unguiculata) cultivation. Results have shown that the treatments with PSB alone or in the form of consortia of compatible strains with or without the external application of chemical NPK gave more germination index (G. I.) from 2.5 to 5 in rice and 2.7 to 4.8 in bean seeds. They also showed a higher growth in both shoot and root length and a higher biomass as compared to the control. This gives us an idea about the potentiality of these PSB strains and their application in rice and yardlong bean cultivation to get a better harvest index. Their use will also possibly reduce the nutrient runoff or leaching and increase in the use efficiency of the applied fertilizers. Thus, we can conclude that the NPK uptake and management can be improved by the use of PSB in rice and yardlong bean cultivation, and their application may be much more beneficial in the agricultural field

Multi-Sensor Based healthcare monitoring system by LoWPAN-based architecture

The development of the Internet of Things (IoT) has recently revived interest in IPv6 over Low-Power Wireless Personal Area Networks (6LoWPAN). For the enormous IP-based detection technologies in the future IoT, 6LoWPAN mobile compatibility is still in its infancy. A significant 6LoWPAN use of IoT, the hospital's wireless technology, which continuously monitors patients' vital signs, regardless of whether they are moving. To track accurate patient positions, communication between patient nodes and the hospital network needs to be maintained through sensor network. In addition, it must offer automatic switching and improve the power consumption of devices. In this research, a hospital structure based on 6LoWPAN with a Media Access Control (MAC) design for patient data was offered. Our preliminary numerical results indicate a decrease in the expenses associated with transfers on the mobile router, which generally represents a bottleneck in such a network. Biological ECG signals are routed via low pan before transmission via routing algorithms to the gateway network
