This paper addresses the single machine early/tardy problem with unrestricted common due date and sequence-dependent setup
times. Two algorithms are introduced to reach near-optimum solutions: the SAPT, a heuristic tailored for the problem, and
a simulated annealing (SA) algorithm. It will be shown that SA provides solutions with slightly better quality; however, SAPT
requires much less computational time. SAPT-SA is a hybrid heuristic that combines both approaches to obtain high quality
solutions with low computational cost. Solutions provided by the three algorithms were compared to optimal solutions for problems
with up to 25 jobs and to each other for larger problems. 相似文献

Wastewater sludge usually contains large amounts of water and organic materials; therefore, its stabilization and dewatering are of particular importance. The present study aimed to investigate the possibility of sludge stabilization and dewatering from wastewater sludge by bioleaching (Thiobacillus ferrooxidans), Fenton/bioleaching, and bioleaching/Fenton-like processes. To evaluate sludge stabilization and dewatering, specific resistance to filtration (SRF), volatile suspended solids (VSS), total suspended solids (TSS), and soluble chemical oxygen demand (SCOD) were measured. In biological treatment with T. ferrooxidans with Fe2+ (2?g?L?1), 99.75, 33, 37, and 72% reduction were observed in SRF, VSS, TSS, SCOD, respectively, after 2 days. In the combined treatment of Fenton before bioleaching (including Fe2+ 2?g?L?1 and H2O2 1?g?L?1 with Fenton oxidation for 30?min followed by biological treatment with T. ferrooxidans for 2 days), the reduction rates in TSS, VSS, SCOD, and SRF were 40.18, 40.88, 60.95, and 75.43%, respectively. In treatment with the combined method of bioleaching before Fenton-like oxidation, the removal rates of the aforementioned parameters were 52.5, 54.4, 88, and 99.82%, respectively. In comparison to Fenton oxidation and bioleaching alone, combined biological method of bioleaching/Fenton-like oxidation using a lower dose of H2O2 and Fe2+ significantly improved sludge dewatering and stabilization. 相似文献

Activated carbon has been proven to be an effective adsorbent for the recovery of a wide variety of metal ions from aqueous solutions. In this research, the activated hard shell of Iranian apricot stones was used for gold recovery from electro-plating wastewater. The effect of parameters such as dose and particle size of adsorbent,pH, agitation speed of mixing on the gold recovery was investigated. The results showed that under the optimum operating conditions more than 98% of gold ions were adsorbed onto activated carbon after just 3 h. In addition, the adsorbed gold could be eluted from this adsorbent by improved striping method. The process involves contact of gold-laden adsorbent with a strong base at ambient temperatures followed by elution with an aqueous solution containing an organic solvent. It was found that activated hard shell of apricot stones has the potential to replace im ported commercial activated carbons in gold adsorption processes. 相似文献

With the increased demand for lightly preserved and/or ready‐to‐eat (RTE) food products, the prevalence of the foodborne pathogen Listeria monocytogenes has increased, which is a public health concern. The goal for this review is to discuss the incidence, epidemiological importance, and contamination routes of L. monocytogenes in various aquatic ecosystems, seafood products, and processing environments and to summarize the data obtained since the 1990s. L. monocytogenes primarily enters the food‐production chain by cross‐contamination in production plants, making this pathogen a major threat to the seafood industry. This pathogen generally contaminates food products at low or moderate levels, but the levels involved in listeriosis outbreaks are significantly higher. The majority of isolates from aquatic products belong to serotype 1/2a, and outbreaks have been linked to highly similar or even indistinguishable strains. Several seafood‐processing plants are colonized by specific “in‐house” flora containing special DNA subtypes of L. monocytogenes. In such cases, L. monocytogenes populations can persist and/or multiply despite the inherent obstacles to their growth in food preservation and manufacturing operations. Therefore, food‐processing facilities must be designed carefully with an emphasis on effective cleaning and disinfecting operations in the production line. 相似文献

Following the previous work (Kaghazchi et al., 2010 [11]), dealing with applying a combination of two kinds of agricultural wastes to produce a new adsorbent, this study is dedicated to investigate the details of mercury adsorption process from aquatic medium by this adsorbent. So the Mix-ZC activated carbon (the sample prepared by chemical activation of a mixture of pistachio-nut shells and licorice residues impregnated with zinc chloride) was selected for doing a series of batch adsorption experiments on it. Equilibrium isotherms, such as Freundlich, Langmuir, Dubinin–Redushkevich and Temkin have been tested. Kinetic studies based on Lagergren first-order, pseudo-second-order rate expressions and intra-particle diffusion studies have been done. The mechanisms of mercury adsorption onto this adsorbent under the operating conditions were also studied. 相似文献

In our previous study, a three‐dimensional gelatin/bioactive glass nanocomposite scaffold with a total porosity of about 85% and pore sizes ranging from 200 to 500 μm was prepared through layer solvent casting combined with lamination technique. The aim of this study was to evaluate in vitro biocompatibility and in vivo bone regeneration potential of these scaffolds with and without endothelial cells when implanted into a critical‐sized rat calvarial defect. MTT assay, SEM observation, and DAPI staining were used to evaluate cell viability and adhesion in macroporous scaffolds and results demonstrated that the scaffolds were biocompatible enough to support cell attachment and proliferation. To investigate the in vivo osteogenesis of the scaffold, blank scaffolds and endothelial/scaffold constructs were implanted in critical‐sized defects, whereas in control group defects were left untreated. Bone regeneration and vascularization were evaluated at 1, 4, and 12 weeks postsurgery by histological, immunohistochemical, and histomorphometric analysis. It was shown that both groups facilitated bone growth into the defect area but improved bone regeneration was seen with the incorporation of endothelial cells. The data showed that the porous Gel/BaG nanocomposite scaffolds could well support new bone formation, indicating that the proposed strategy is a promising alternative for tissue‐engineered bone defects. 相似文献
