Impact of Sensor Motes on Web Server of IEEE 802.15.4 for Wireless Sensor Networks
Main aspire of this paper is to observe the outcome of diverse sensor motes namely BPART, MOTEIV, Z1 on web server of IEEE 802.15.4 in case of Wireless Sensor Networks (WSNs). The three motes are studied by keeping all the other factors same in all the three cases. The results are compared on the basis of collision status, packets marked noise, media access delay, throughput, end to end delay. These parameters are considered at physical, MAC and application layers and results were analyzed. Overall, it is concluded that if the performance of the web server is to be enhanced then there has to be trade-off for utilization of motes in the IEEE 802.15.4 (WSNs) connected to web server
Role of arbuscular mycorrhizal fungi (AMF) in global sustainable development
Mycorrhizal symbiosis is a highly evolved mutually beneficial relationship that exists between Arbuscular Mycorrhizal Fungi (AMF) and most of the vascular plants. The majority of the terrestrial plants form association with Vesicular Arbuscular Mycorrhiza (VAM) or Arbuscular Mycorrhizal fungi (AMF). This symbiosis confers benefits directly to the host plant’s growth and development through the acquisition of Phosphorus (P) and other mineral nutrients from the soil by the AMF. In addition, their function ranges from stress alleviation to bioremediation in soils polluted with heavy metals. They may also enhance the protection of plants against pathogens and increases the plant diversity. This is achieved by the growth of AMF mycelium within the host root (intra radical) and out into the soil (extra radical) beyond. Proper management of Arbuscular Mycorrhizal fungi has the potential to improve the profitability and sustainability of agricultural systems. In this review article, the discussion is restricted to the mycorrhizal benefits and their role in sustainable development
Solid Wastes Recyling through Sinter-Status at Tata Steel
Integrated steel plants generate several by-products rich in iron, flux and fuel values, categorised as waste. These by-products contain, besides mineral values, hazar-dous constituents causing damages to the environment. The environmental quality consciousness, the product cost competitiveness and high mineral values of these wastes have resulted in attempts to recyle these materials. Recycling recovers the mineral values, preserves the dec-reasing natural resources and deteriorating environment and eliminates the disposal cost. Sinter plant provides an avenue for recycling of these wastes. Recycling decreases the cost of sinter and hence the cost of steel produced. Present paper outlines the status of waste generation, their characteristics, and the quantity being recycled via the sinter plant at Tata Steel.Furthermore, it highlights the problems, which restricts its further recycling and
discusses its influence on cost and quality of sinter
Diphtheria, pertussis, and tetanus vaccine-induced extensive longitudinally extensive transverse myelitis: A case report
Transverse myelitis (TM) has been reported in association with vaccination, including post-diphtheria, pertussis, and tetanus (DPTw) vaccination. Here, we report the case of a 21-month-old female child presented with loss of neck control with a history of DPTw booster vaccination approximately 4 weeks before this illness. The child was referred to the tertiary care service hospital. Magnetic resonance imaging of the spine revealed longitudinally extensive TM in the cervical segment. Extensive investigation effectively excluded causes other than vaccination-associated TM. Following treatment with corticosteroids and intravenous immune-globulin, the child had a complete recovery. Early diagnosis and prompt treatment with immunotherapy are associated with a good outcome
Effect of wheat bran and dried carrot pomace addition on quality characteristics of chicken sausage
Objective Effect of addition of wheat bran (WB) and dried carrot pomace (DCP) on sensory, textural, colour, physico-chemical and nutritional characteristics of chicken sausage were evaluated. Methods WB and DCP were used as a source of dietary fibre at 3%, 6%, and 9% level individually. Different quality attributes of sausages were estimated. One product from each source with very good sensory acceptability was selected to analyze dietary fibre content and shelf life under refrigerated storage. Results Sensory acceptability of 3% fibre enriched sausage was comparable with control and a further increase in fibre level resulted in a decrease in sensory acceptability. Fibre enriched sausages were significantly harder and less cohesive than control sausage. Significant increase in gumminess and chewiness was observed at 6% level in WB treated sausages and 9% level in DCP treated sausages. Moisture content decreased significantly in all treated sausages, protein content decreased significantly in DCP-2 and DCP-3 sausages while fat content decreased in all WB and DCP-3 treated sausages in comparison to control. The fibre enriched sausage had significantly higher dietary fibre and lower cholesterol content. Cooking yield and emulsion stability increased in treated sausages and a significant difference was noticed at 6% level in both types of sausages. pH of WB treated sausages was significantly higher and DCP treated sausage significantly lower in comparison to control. Conclusion The results of present study indicate that fibre enriched chicken sausage with moderate acceptability can be developed by incorporating WB and DCP each up to 9% level. Chicken sausage with very good acceptability, higher dietary fibre content and storability up to 15 days at refrigerated temperature can be developed by incorporating WB and DCP at 6% level each

Effect of superphosphate, urea and bioinoculants on Zinnia elegans Jacq.
Current agricultural practices depend heavily on chemical inputs, and their overuse seriously contaminates the soil health. Microbial bioinoculants are emerging as an effective greener replacement for chemical fertilizers. These bioinoculants are beneficial for plant growth and also diminishes pathogenicity. Here, we explored three microbial inoculants along with commonly used fertilizers, i.e., Superphosphate (SP) and Urea (UR) for their effectiveness on Zinnia elegans Jacq., that has considerable demand in the floral market. The experiment was conducted in three parts with recommended doses of fertilizers, low (half) doses, and high (double) doses in combination with Glomus mosseae (GM), Acaulospora laevis (AL) and Pseudomonas fluorescens (PF), as microbial inoculants. The consortium of microbial inoculants (GM+AL+PF) fed with the low dose of SP and UR gave the best results for growth parameters (Shoot and Root Length, Shoot and Root Weight), Floral traits (floral head number and diameter), mycorrhization pattern and for other physiological attributes (shoot phosphorus content, root phosphorus content, acidic phosphatase, alkaline phosphatase). Overall, the study establishes that microbial bioinoculants is a potential fertilizer supplement at the recommended dose supports optimum Z. elegans growth
Structural phase transitions in perovskite BaCeO3 with data mining and first-principles theoretical calculations
Several experiments conducted over decades have revealed that the
perovskite-structured BaCeO3 goes through a series of temperature-induced
structural phase transitions. However, it has been frequently observed that the
number of phases and the sequence in which they appear as a function of
temperature differ between experiments. Insofar as neutron diffraction and
Raman spectroscopy experiments are concern, four structures are well
characterized with three transitions: Pnma to Imma [563 K] to R-3c [673 K] to
Pm-3m [1173 K]. In contrast, thermoanalytical methods showed multiple
singularities corresponding to at-least three more structural transitions at
around 830 K, 900 K, and 1030 K. In account of these conflicting experimental
findings, we computed free energy phase diagram for BaCeO3 employing crystal
structure data mining in conjunction with first principles electronic structure
and phonon lattice dynamics. A total of 34 polymorphs have been predicted, the
most stable of which follows the Glazer classification of the perovskite tilt
system. It has been predicted that the Cmcm and P4/mbm phases surpass Pnma at
666 K and 1210 K, respectively. At any temperature, two alternate tetragonal
phases (P42/nmc and I4/mcm) are also found to be 20 to 30 meV less favored than
the Pnma. While the calculated stability order of the predicted polymorphs is
in acceptable agreement with the results of neutron diffraction, the
transitions observed in thermoanalytical studies could be ascribed to the
development of four novel phases (Cmcm, P4/mbm, P42/nmc, and I4/mcm) at
intermediate temperatures. However, we analyze that the R-3c phase
predominantly stabilized over a broad temperature field, masking all subsequent
phases up until the cubic Pm-3m. Consequently, the novel phases predicted to
occur in thermoanalytical studies are only fleetingly metastable.Comment: 20 pages, 5 figures, 1 tabl
