The spatial variation of poplars’ reproductive phenology in Beijing’s urban area has aggravated the threat poplar fluff (cotton-like flying seeds) to public health. This research explored impact microclimate conditions on female Populus tomentosa Taoranting Park, a micro-scale green space Beijing (range <1 km). observed phenophases covered flowering, fruiting, and seed dispersal, ENVI-MET wa...

Commercial poultry hatcheries provide ideal conditions for the multiplication and spread of microorganisms. Formaldehyde is widely used as a disinfectant; however, it harmful to human health can cause abnormal morphology in chicks. An alternative microbiological control use copper, metallic antimicrobial agent contact surfaces. The efficacy copper surfaces has been established healthcare enviro...

Flax (Linum usitatissimum) is widely used as a source of linen oil and fiber. As rule, the flax varieties are suitable for either seeds or stem fibers production. The “fiber” bring low seed, while “oil” ones have poor fibers. straw not textile industry has to be burned degraded naturally in field. However, it contains DP cellulose, which can at least varnish main challenge industrial applicatio...

The aim of this study is the thermal recovery of manganese and zinc from a mixture of zinc-carbon and alkaline spent batteries containing 40.9% of Mn and 30.1% of Zn after a preliminary physical treatment. Separation of the metals is carried out on the basis of their different phase change temperatures, the boiling point of zinc being 906°C and 1564°C that of Mn3O4, the main Mn-bearing phase in...

Clostridium perfringens strains (type A) isolated from an integrated poultry operation were subtyped using repetitive-element PCR with Dt primers. Isolates were obtained from fecal, egg shell, fluff, and carcass rinse samples as part of a previously reported temporally linked epidemiological survey. A total of 48 isolates of C. perfringens were obtained from different stages of the broiler chic...

The properties of interstellar matter (ISM) at the Sun are regulated by our location with respect to the Local Bubble (LB) void in the ISM. The LB is bounded by associations of massive stars and fossil supernovae that have disrupted natal ISM and driven intermediate velocity ISM into the LB interior void. The Sun is located in such a driven ISM parcel, which is low density (< 10 g cm). The Loca...

The problem of evolving an artificial ant to follow the Santa Fe trail is used to study the well known genetic programming feature of growth in solution length. Known variously as “bloat”, “fluff” and increasing “structural complexity”, this is often described in terms of increasing “redundancy” in the code caused by “introns”. Comparison between runs with and without fitness selection pressure...
