In this work, a novel thinner derived from natural botany Chinese Larch Tree was obtained by combination lignin with phenol using H2O2 as oxidant and the acting efficiency of lignosulfonate in the drilling fluids is greatly enhanced after oxidation with H2O2. Both the chemical structure and the adsorptive ability of the oxidation...

Since the early 1980s, the research community has developed ever more sophisticated algorithms for the problem of energy disaggregation, but despite decades of research, there is still a dearth of applications with demonstrated value. In this work, we explore a question that is highly pertinent to this research community: how good does energy disaggregation need to be in order to infer characte...

mucosa-adhesive gels can be used as a useful mean of delivering drugs to or via mucosal membranes, and in particular buccal mucosa. carbomers are among the best mucosa-adhesive materials known. the aim of this study was to compare the results obtained from the mucosa-adhesive strength of aqueous gels containing carbomers, either alone or in combination, to the data obtained from assessing the d...

The treatment of Chagas disease is limited by the frequent cutaneous side effects of benznidazole. We tested the use of steroids plus escalating doses of benznidazole to prevent this complication in 17 adult patients with chronic Trypanosoma cruzi infection and found extremely good tolerance. A randomized trial is warranted.
