Quantitative NMR (qNMR) is applied to determine the absolute quantitative value of analytical standards for HPLC-based quantification. We have previously reported optimal and reproducible sample preparation method qNMR hygroscopic reagents, such as saikosaponin a, which used an standard in assay crude drug section Japanese Pharmacopoeia (JP). In this study, we examined purity determination a su...

Flame control, particularly at very lean conditions, is a critical requirement for external combustion power sources such as thermoelectric and thermophotovoltaic generators. The availability of in-situ produced hydrogen from JP-8 fuel reforming presents a potential supply of hydrogen on the battlefield without adding a second fuel to the logistics system. Dual firing of hydrogen with light hyd...

In this paper, we apply the method of QCD sum rules to study doubly heavy tetraquark states [Formula: see text] with spin-parity and strangeness using careful estimates Borel threshold parameters involved. Masses bottom charmed tetraquarks isospin are computed precisely via taking into account multifarious condensates up dimension 10. Compared two-heavy meson thresholds, find that all nonstrang...

Aquatic and semi-aquatic mammals, while resting at the water surface or ashore, breathe with a low frequency (f) by comparison to terrestrial mammals of the same body size, the difference increasing the larger the species. Among various interpretations, it was suggested that the low-f breathing is a consequence of the end-inspiratory breath-holding pattern adopted by aquatic mammals to favour b...

Let G be a finite group and suppose that the set of conjugacy class sizes of G is f1;m;mng, where m; n > 1 are coprime. We prove that m 1⁄4 p for some prime p dividing n 1. We also show that G has an abelian normal p-complement and that if P is a Sylow p-subgroup of G, then jP 0j 1⁄4 p and jP=ZðGÞpj 1⁄4 p. We obtain other properties and determine completely the structure of G.

Flow reactors are commonly employed in investigations of the pyrolysis and oxidation chemistry fuels. Typical flow use either electrical heaters or vitiation to provide energy preheat reactants desired experimental conditions. The present study seeks determine impact on reactor studies fuel combustion by conducting both experiments a which an heater is used as source. Other than all other aspec...

Jerami padi adalah salah satu limbah pertanian yang melimpah di Indonesia dapat digunakan sebagai sumber lignoselulosa untuk produksi biogas. Salah metode meningkatkan biogas dengan menambahkan cairan rumen dan kotoran sapi. Penelitian ini membandingkan pada sapi (JP-R) campuran (JP-RKS). Percobaan dilakukan dalam reaktor <em>batch</em> anaerob selama 30 hari volume kerja 3,6 L suhu...
