Abstract Diphenylamine (DPA), formyl chloride, and sodium hydride (NaH) as raw materials synthesize methyldiphenylurea stabilizer by alkylation reaction. The physical chemical properties of were characterized nuclear magnetic resonance hydrogen spectrum (1HNMR), X-ray energy (EDS), Fourier transforms infrared spectroscopy (FT-IR) differential thermal analysis (DTA). Thermal Decomposition Experi...

The demand to synthesize economical detoxification adsorbents of organic pollutants has been a thriving solicitude for most environmental research aspirants. Here, we synthesized titanium(III) oxide doped with spherical shaped meta-aminophenol formaldehyde magnetic microspheres (Ti2O3/mAPF MMSs) by the polymerization method Ti2O3 nanoparticles and m-aminophenol. SEM analysis confirmed material ...

We describe a technique that maps unranked trees to their hash codes using a bottom-up deterministic tree automaton (DTA). In contrast to techniques implemented with minimal tree automata, our procedure builds a pseudo-minimal DTA. Pseudo-minimal automata are larger than the minimal ones but in turn the mapping can be arbitrary, so it can be determined prior to the automaton construction. We al...

Recent advances in Immuno-Oncology (IO) have shown that the immune system can be activated to induce long term durable anti-tumor responses. For IO drug development, immune activation is typically explored using rat surrogate antibodies in immunocompetent mouse models. While these models can be used to show efficacy in vivo, the development of anti-drug immune responses to experimental protein-...

Consider a 2NTA A, and let k be the magnitude of the largest constant appearing in a clock constraint in the transitions of A. Given a timed word w = (;) of length n, deene R w to be the set comprising of i + c and (i + j + c)=2 for 1 i; j n ...

چکیده در این مقاله، نانوذرات فریت بیسموت (BiFeO3) به روش سل-ژل تهیه شدند. برای پی‌بردن به گسترۀ دمایی پخت نانوذرات فریت بیسموت آنالیز توزین حرارتی (TGA) و آنالیز حرارتی تفاضلی(DTA) بر روی ژل خشک آن انجام شد. به‌منظور بررسی خواص ساختاری و نوری نمونه‌ها با استفاده از نتایج آنالیزهای حرارتیTGA و DTA عملیات پخت در دماهای 600، 650، 700، 750، 800 و °C850 انجام شد. سپس خواص ساختاری نمونه‌ها با آ...

The Haft Sandogh alunite deposit is located in the northwest of Takestan (about 60 Km west of Qazvin), and is a part of large Takand alunite deposit. Mineralogical and field study reveal that there is a zonation in the alteration zones of the Haft Sandogh deposit and surrounding area including silica zone in the central part, and quartz-alunite (quartz alunite), kaolinite and propylitic formed ...

AIM To investigate the reproducibility of the updated Standards for the Reporting of Diagnostic Accuracy Studies tool (STARD 2015) in a set of 106 studies included in a Cochrane diagnostic test accuracy (DTA) systematic review of imaging tests for diagnosing manifest glaucoma. METHODS One senior rater with DTA methodological and clinical expertise used STARD 2015 on all studies, and each of t...

The deteriorating effect of corrosion can be controlled by applying suitable polymeric-based coatings. In this work, polyolefin based smart composite coatings containing modified halloysite nanotubes decorated with ceria particles were investigated to analyze their anti-corrosion behavior. For purpose, (Hals) utilized as nanocarriers which loaded sodium dodecyl sulfate (SDS) a inhibitor via ove...

OBJECTIVE To investigate diagnostic test accuracy (DTA) of different tests for obstructive sleep apnea (OSA) compared to polysomnography (PSG) in children. METHODS We performed a systematic review according to DTA criteria published by the Cochrane Collaboration. Studies that compared any possible diagnostic test with PSG for diagnosing OSA were considered. Study quality assessment was conduc...
