Sustainable development of concrete construction requires sustainable materials or binders. Specifically, alkali-activated (AAMs) are an interesting and wide group materials. They have good strengths considered environmentally friendly because secondary consumed during the preparation AAMs. The durability AAMs is also excellent. One most important parts frost resistance. resistance usually very...

thionyl chloride (or oxalyl chloride) has been used as an efficient and cheap acid activator for one-pot synthesis of β-lactams in good to excellent yields by reaction between imines and acids in the presence of triethylamine at room temperature.

acquired azole resistance in opportunistic fungi causes severe clinical problems in immunosuppressed individuals. this study investigated the molecular mechanisms of azole resistance in clinical isolates of candida glabrata . six unmatched strains were obtained from an epidemiological survey of candidiasis in immunocompromised hosts that included azole and amphotericin b susceptible and azole r...

objective: to evaluate the efficacy and safety of intravenous and catheter directed thrombolysis by recombinant tissue plasminogen activator (alteplase) in the patients with non-traumatic acute limb ischemia (ali). methods: this was a randomized clinical trial being performed between 2009 and 2011 in mashhad university of medical sciences. we included those patients who were<75 years, with symp...

poly(styrene-co-butyl acrylate)/clay nanocomposites were synthesized via in situ atom transfer radical polymerization using activators generated by electron transfer in the presence of a montmorillonite ion-exchanged with mixed surfactants of dodecyl trimethyl ammonium bromide and vinyl trimethyl ammonium chloride. the living nature of polymerization is confrmed by occurrence of narrow molecula...

tissue plasminogen activator (tpa) is a serine protease, which is composed of five distinct structural domains with 17 disulfide bonds, representing a model of high-disulfide proteins in human body. one of the most important limitations for high yield heterologous protein production in escherichia coli (e. coli) is the expression of complex proteins with multiple disulfide bridges. in this stud...

Abstract Based on the knowledge that exists today, it is generally accepted there are basic parameters and characteristics to obtain effective mixtures for their use in 3D printing. Rheological behavior setting time (initial final) those determine workability, as well speed nature of hardening molded pastes and, a result, final framework integrity resulted structure. Among promising options pri...

The purpose of research to measure and analyse the quality quantity food waste composting by adding cow rumen activator efective microorganisme (EM4). This do identify dominant bacteria that play a role in composting. method applied this is Takakura for bacterial identification was referred as Bergey's manual which consisted gram stain test biochemical test. Three types composter variation are ...
