The operating conditions can have uncontrolled effects on the voltage of a High-Temperature Proton Exchange Membrane Fuel Cell (HT-PEMFC). For instance, HT-PEMFC be used at ambient pressure, i.e., without having back pressure regulator. In this case, variation in atmospheric directly affects pressures inside fuel cell, which induces variation. Moreover, transient phases, several coupled phenome...

1,3-butadiene is an essential platform chemical for producing rubberlike polymers, which extracted from C4 hydrocarbons that are produced through steam cracking. The current state-of-the-art technology the BASF process uses thermally coupled extractive distillation (ED) followed by two columns. However, requires high temperature heat input, thus cost hot utility and reduces possibility integrat...

Two experiments were conducted to examine the influence of addition of microbial phytase to diets differing in native phytase content, on the performance of sows and digestibility of nutrients. Barley and wheat grains relatively poor in native phytase used in Experiment 1 mixtures were replaced by triticale and rye (rich in this enzyme) in Experiment 2 diets. There were 3 groups in each experim...

OBJECTIVES The 30-minute rule for RBC concentrates out of controlled temperature storage does not take into account multiple parameters that influence warming of RBC concentrates. This study evaluated two temperature-sensitive indicators (TIs) for monitoring RBC concentrates during transport. METHODS TI labels (Check-Spot [Harald H. Temmel KG, Gleisdorf, Austria] and Thermoindikator V4 [BASF,...

The title compound, C22H18N4OS, crystallized with four independent mol-ecules (A, B, C and D) in the asymmetric unit. All four mol-ecules have a Z conformation about the C=N bond with the benzyl ring being inclined to the indoline ring mean planes by 73.4 (2), 77.9 (2), 73.2 (2) and 77.2 (2)° in mol-ecules A, B, C and D, respectively. In mol-ecules A and B, the phenyl ring is inclined to the me...

A consistent framework is developed for studying hadronic form factors of heavy mesons using QCD sum rules in the heavy quark effective theory, including the-next-to-leading order renormalization group improvement. Sum rules are derived for the asymptotic value of the meson decay constant jp and for the universal Isgur-Wise form factor. It is shown that renormalization group effects considerabl...

Because of the uniqueness geological mineralization, tailings obtained from Chenchao Iron Mine have low SiO2 content only 27.80%. Content Al2O3 and MgO is 13.31% CaSO4 22.09%. The fineness modulus ores large enough for convenient mineral separation, thus resulting in 16.03% −5 μm particles 27.76% −10 tailings, respectively. average particle size 69.36 μm; it belongs to category very fine tailin...

copper trimesate (cu-btc) mof has been pointed out as a promising adsorbent for separating carbon dioxide from methane. however, mof’s need to be shaped prior to their use in packed bed adsorbers in order to reduce pressure drop; on the other hand, the production of mechanically resistant shaped bodies reduces their adsorption performance. in this work, cu-btc tablets provided by basf are evalu...

Latar Belakang: Tercukupinya kebutuhan akan asupan asam lemak tidak jenuh ganda (polyunsaturated fatty acids, PUFA) dan status gizi ibu hamil yang optimal diketahui memiliki peran penting dalam mendukung pertumbuhan perkembangan otak janin bayi. Studi menunjukkan bahwa PUFA di beberapa daerah Indonesia sangat rendah juga masih banyak kurang. Kedua masalah pada tersebut diduga berpengaruh terhad...

The hyperthermophilic archaeon Sulfolobus solfataricus contains an unusual large number of sugar binding proteins that are synthesized as precursors with a class III signal peptide. Such signal peptides are commonly used to direct archaeal flagellin subunits or bacterial (pseudo)pilins into extracellular macromolecular surface appendages. Likewise, S. solfataricus binding proteins have been sug...
