Flotation Collector

Single flotation collector can not effectively extract the various valuable minerals from the complex ores simultaneously. Combined use of many collectors is one of the best ways to solve the problem, because the synergistic effect induced by the multifunctional composite chemical reagents will exert positive effect to the flotation and increase the recovery. The synergy is related with the reagent types, characteristics, and component contents in the mixture, and it is critical to choose and design the combination of various reagents. The maximal effect from synergy can be obtained easily by confecting the blended reagents. So the use of mixed collectors on the flotation of minerals has both benefits of reducing the costs and increasing the flotation efficiency.

The objective of this study was to evaluate the effect of combining catechin, protocatechuic, and vanillic acids against planktonic growing, adhesion, and biofilm eradication of uropathogenic Escherichia coli (UPEC), as well as antioxidant agents. The minimum inhibitory concentrations (MIC) of protocatechuic, vanillic acids and catechin against the growth of planktonic bacteria were 12.98, 11.80, and 13.78 mM, respectively. Mixing 1.62 mM protocatechuic acid + 0.74 mM vanillic acid + 0.05 mM catechin resulted in a synergistic effect acting as an MIC. Similarly, the minimum concentrations of phenolic compounds to prevent UPEC adhesion and biofilm formation (MBIC) were 11.03 and 7.13 mM of protocatechuic and vanillic acids, respectively, whereas no MBIC of catechin was found. However, combinations of 1.62 mM protocatechuic acid + 0.74 mM vanillic acid + 0.05 mM catechin showed a synergistic effect acting as MBIC. On the other hand, the minimum concentrations to eradicate biofilms (MBEC) were 25.95 and 23.78 mM, respectively. The combination of 3.20 mM protocatechuic acid, 2.97 mM vanillic acid, and 1.72 mM catechin eradicated pre-formed biofilms. The antioxidant capacity of the combination of phenolics was higher than the expected theoretical values, indicating synergism by the DPPH•, ABTS, and FRAP assays. Effective concentrations of catechin, protocatechuic, and vanillic acids were reduced from 8 to 1378 times when combined. In contrast, the antibiotic nitrofurantoin was not effective in eradicating biofilms from silicone surfaces. In conclusion, the mixture of phenolic compounds was more effective in preventing cell adhesion and eradicating pre-formed biofilms of uropathogenic E. coli than single compounds and nitrofurantoin, and showed antioxidant synergy.

Purpose The purpose of this study is to advance and test the idea that product exports and technology imports are complementary cross-border learning approaches for emerging market firms’ innovation performance. In addition, this paper also seeks to search for contextual variables that affect this complementarity. Design/methodology/approach This study takes systems approach to examine complementarity, combining a “productivity” and an “adoption” approach. In addition, interaction approach is also used as robustness check. Findings The authors show that the positive effect of export activity on firms’ growth rate is higher for firms that also engage in technology import, and vice versa. Furthermore, they show that, Ceteris paribus, firms’ adoption of one cross-border learning mechanism (e.g. entering export markets) positively influences the adoption of the other (e.g. technology import). Moreover, this complementarity is only significant for firms from province with low level of marketization. Research limitations/implications This inconsistency about learning-by-exporting and technology import on innovation can be resolved, at least partially, by the complementarities perspective. This paper also reveals two mechanisms of learning-by-exporting: the indirect effect of export on innovation through increasing the likelihood of adoption decision of importing technology and enhancing the positive effect of technology imports. Practical implications The potential of combining the two strategies should not be ignored by managers. To improve regional competitiveness, local governments should try best to improve the efficiency of customs to help firms realize the synergistic effect of learning-by- exporting and learning-by-technology-importing. Originality/value This study first explores the positive complementarity between the two cross-border learning mechanism in sharping EEEs 2019 innovation performance and identifies the condition to realize the synergistic effect of learning-by-exporting and learning-by-technology-importing.

In this research, the synergistic effect of trisodium citrate (TSC) and microbial transglutaminase (TGase) treatment on the textural properties of acidified yak skim milk gels was investigated. TSC was added to yak skim milk to concentrations of 0, 20, and 40 mmol/L, followed by adjusting the pH to 6.7. The samples were incubated with TGase for the cross-linking reaction, after which the samples were acidified with 1.4% (w/v) gluconodelta-lactone (GDL) at 42°C for 4 h to form gels. The stiffness and water holding capacity (WHC) of gels exhibited higher values at 20 or 40 mmol/L than without TSC. The final storage modulus (G′) of yak milk gels was positively related to the concentration of TSC prior to TGase treatment. Cryoscanning electron microscopy observations showed that the gel networks were more rigid with higher TSC concentrations. Overall, TSC dissociated particles in yak milk into smaller ones. The newly formed particles in yak skim milk could form acid-induced gels with greater stiffness and higher WHC in the presence of TGase.

BACKGROUND: Risk stratification systems, one of the optimal solutions for differential diagnosis of nodular pituitary disorders, are currently under development. The high prevalence of pituitary diseases makes it necessary to evaluate the effectiveness of risk stratification systems and to widely implement them into routine clinical practice. AIM: To evaluate the effectiveness of modern risk stratification systems used to diagnose nodular pituitary disorders. MATERIAL AND METHODS: A total of 1,606 medical records of patients operated on for nodular pituitary disorders in 20062014 were analyzed. The preoperative ultrasonography results and cytological findings were evaluated. The ultrasonography results were classified using the TI-RADS system, while the biopsy data were classified using the TBSRTC system. The surgery protocol and the pathomorphological data were the truth criterion. The effectiveness of the TI-RADS and TBSRTC systems, as well as their contribution to the performance of endocrinologists in outpatient clinics, was analyzed. RESULTS: Cluster analysis revealed a significant volatility of ultrasonography signs in the TI-RADS category, while there was no dominant sign that could be considered the diagnostic standard. Factor analysis proved the consistency of the imaging TI-RADS system based on individual signs. The signs being evaluated are characterized by high significance level but different priorities depending on the type of putative pathology. Discriminant analysis revealed that TI-RADS was a robust and versatile system to be used for various types of nodular pituitary disorders. The overall effectiveness of the TI-RADS system in diagnosis of pituitary tumors was low: it was characterized by 75.4% sensitivity, 84.7% specificity, and 80.1% accuracy. However, this system concretized the indications for fine-needle aspiration biopsy and drew the cytologists attention to the likelihood of pituitary tumor. The implementation of the TBSRTC system reduced the percentage of non-informative (by 9.8%) and controversial results (by 1.7%). Cytological examination was more effective in detection of pituitary cancer compared to ultrasonography (91.0% accuracy, 94.9% specificity, and 76.5% sensitivity). The impressions of ultrasound technicians and cytologists were concordant in 873 (54.4%) cases. A survey conducted among endocrinologists in outpatient clinics showed that implementation of the TI-RADS and TBSRTC risk stratification systems reduced the decision time (p0.001) and errors both in diagnostics (p0.001) and treatment approach selection (p0.001). CONCLUSION: The combined use of the TI-RADS and TBSRTC systems allows one to personalize the treatment approaches for patients with nodular pituitary disorders. The implementation of these systems has a positive effect on endocrinologists performance as it reduces the decision time and the likelihood of making errors in diagnosis and treatment strategy selection.
