Disposal and storage of raw poultry manure has become an environmental problem because of the associated air, water and soil pollution. Poultry manure begins to decompose immediately after excretion giving off ammonia which, in high concentrations, can have adverse effects on the health and productivity of birds as well as the health of the farm workers. Application to land is the most common w...

In a 10-ton capacity pilot plant solar liquid desiccant air conditioner (LDAC) developed, dehumidification of the outside air is achieved through a honeycomb packed-bed heat and mass exchanger, using lithium chloride solution as the desiccant. The dry air obtained from the dehumidification process is evaporative cooled inside a cooling pad and directed into the conditioned space. The dilute sol...

The collapse of the Fundão dam in Brazil caused one biggest environmental disasters. One challenges was how to manage tailings so that affected areas could be reused. This study aimed verify whether applying different irrigation depths Xaraés grass grown with iron mining would affect shoot and root dry masses. experiment set up a randomized design five (40%, 60%, 80%, 100%, 120% crop evapotrans...

Abstract Super absorbent polymer is a new type of functional material that has been researched in recent decades. Due to its special structure and water-absorbing water-retaining properties, it broad field drought resistance, soil improvement crop protection. It conditioner agricultural drought-resistant water-saving materials. Combining with fertilizers prepare forestry slow-release functions,...

Mining activities has generated large amounts of mine tailings each year, and these usually contain high concentrations heavy metal pollutants, which not only cause serious damage to the local surrounding soil ecosystems, but also harm human health via transmission food chain. Phytoremediation is treated as environmentally friendly, long-term effective low-cost restoration method. However, tail...

application of outflow water from treatment plants for irrigation as a non-usual water resource is being developed due to the lack of usual water resources in iran. activated carbon as a conditioner in water treatment procedures causes undesired changes in hydraulic properties of porous media and soil degradation. in this paper, the effects of activated carbon concentration on hydrodynamic prop...

Abstract Glycophyte biomass-derived biochars are currently concerned in most studies. However, little attention is given to the characteristics of halophyte-derived biochars. In this study, five typical halophytes euhalophytes ( Suaeda altissima , salsa and Kalidium foliatum ), recretohalophytes Phragmites australis pseudohalophytes Tamarix chinensis ) which widely distributed arid semiarid reg...

In this paper, we propose a traffic conditioner with promotion and fairness guarantee (TC_PFG) schemes to amend the inappropriate marking by conventional traffic conditioners. The TC_PFG is based on the Two Rate Three Color Marker (TRTCM) scheme. It can allocate appropriate bandwidth to micro-flows to reduce the unfair distribution among micro-flows and improve the utilization by allowing promo...
