In the present research, charging carbon composite briquettes (CCB) in a blast furnace (BF) was investigated. The CCB used contained 29.70 wt.% Fe3O4, 39.70 wt.%, FeO, 1.57 iron, 8.73 gangue, and 20.30 carbon. Its reaction kinetics BF examined by nonisothermal tests modeled. Thereafter, influence of replacing 10% ore with on performance studied numerical simulations. Results showed that behavio...

To study the caving of thick hard overburdens and evolution water-conducting fracture zones in fully mechanized top-coal faces gently inclined extra-thick coal seams, we comprehensively analyzed 8103 working face Beixinyao Coal Mine. We investigated to characteristics overburden faces, information internal structure overburden, development heights “two zones” after mining. Our research methods ...

The critical zone (CZ) includes natural and anthropogenic environments, where life, energy matter cycles combine in complex interactions time space. Critical observatories (CZOs) have been established around the world, yet their limitations space duration of observations, as well oft-existing dominant disciplinary research field(s) each CZO may limit transferability local knowledge to other set...

BACKGROUND AND AIMS Banana finger drop is defined as dislodgement of individual fruits from the hand at the pedicel rupture area. For some banana varieties, this is a major feature of the ripening process, in addition to ethylene production and sugar metabolism. The few studies devoted to assessing the physiological and molecular basis of this process revealed (i) the similarity between this pr...

In response to changes in phloem supply, adenylate demand, and oxygen status, legume nodules are known to exercise rapid (seconds to hours) physiological control over their permeability to oxygen diffusion. Diffusion models have attributed this permeability control to the reversible flow of water into or out of intercellular spaces. To test hypotheses on the mechanism of diffusion barrier contr...

Production scheduling in underground mines is still a manual process, and achieving a truly optimal result through manual scheduling is impossible due to the complexity of the scheduling problems. Among the underground mining methods, sub-level caving is a common mining method with a high production rate for hard rock mining. There are limited studies about long-term production scheduling...

Henna (Lawsonia inermis L.) is a commercial and export-oriented important perennial shrub used in the ornamentation of palm, feet, dyeing hair, etc. Developing high-yielding varieties elite plant materials are best method to increase productivity quality henna. An experiment was conducted at research farm ICAR-Central Arid Zone Research Institute, Regional Station, Pali-Marwar, Rajasthan during...

background and aim: auditory p300 is an event-related potential. cognitive factors like attention are involved in the generation of p300. it seems that normative variation of p300 is necessary for clinical purposes. thus, the current study was designed to establish preliminary normative variation of p300 amplitude and latency at fz and cz sites in adults. methods: this cross-sectional study was...
