Solid fuelization technology can increase the heating value of sewage sludge such that it be utilised as a fossil fuel substitutes. Reducing landfilling bottom and fly ash resulting from heavy metals contained in is challenging. Hence, combustion melting (CMT), which discharge form slag, has been proposed herein an alternative to conventional incineration technology. However, further research r...

The reclaimed water produced by sewage treatment plants can be reused for many purposes, which has gradually been paid great attention. However, its pricing mechanism not well established especially in China, brought certain restrictions on the wide application of water. Therefore, this paper attempts to analyze current situation domestic pricing, combined with research and analysis production ...

OBJECTIVE To evaluate the risk of hepatitis A virus (HAV) infection among sewage workers from occupational exposure to raw sewage. METHODS An analytical cross sectional study of 241 company employees with possible occupational exposure to sewage in a large water and sewerage company was carried out. Previous exposure to hepatitis A virus infection was assessed, as were its associations with p...

We estimate the profitability of producing biochar from crop residue (corn stover) for two scenarios. The first employs slow pyrolysis to generate biochar and pyrolysis gas and has the advantage of high yields of char (as much as 40 wt-%) but the disadvantage of producing a relatively low-value energy product (pyrolysis gas of modest heating value). The second scenario employs fast pyrolysis to...

Traumatic optic neuropathy (TON) refers to any insult to the optic nerve secondary to trauma. The incidence of TON after traumatic head injury in various studies ranges from 0.5-2.3%. An impact injury to the optic nerve often resulting in significant visual loss and even blindness.The vast majority of TON cases are seen in males,around thirty years of age. TON can be classified depending on the...

U sing the expansion-cham ber m ethod, n inety p ro ton tracks are obtained from 850 pho to ­ graphs showing the d isintegration of nitrogen under bom bardm ent by slow a-particles. The num ber of disintegrations decreases as the energy of the a-particles is reduced, b u t the photographs show disintegrations occurring for energies less th an T7 MeV. The angular dis­ tr ibu tion is approxim ate...

This study was conducted to evaluate the effect of fasting period with or without enzyme supplementation on body weight, body weight gain, feed intake, and feed conversion ratio; carcass traits and blood parameters of broilers. One hundred sixty eight, one day old, Cobb broiler chicks were randomly distributed into eight treatments. Each treatment included three replicates each with 7 birds. Bi...
