La guerra de Successió va ser un conflicte bèl·lic però també propagandístic. Entre escriptura i oralitat, una les formes propagació més efectives missatges polítics van els contrafacta, textos dissenyats per cantar-se amb melodies preexistents. Aquests circulaven en forma fulls volanders o petits plecs, aquests objectes físics només s’hi reproduïen textos; tonades què es cantaven, àmpliament c...

In this work, molecular dynamics (MD) simulations were employed to investigate the effects of duty cycle changes and utilization of tantalum nitride interlayer on the surface roughness and adhesion of Ta coating deposited by pulsed-DC plasma assisted chemical vapor deposition. To examine the simulation results, some selected deposition conditions were experimentally implemented and characterize...

PURPOSE This study aims to investigate the prevalence of the two known telomere maintenance mechanisms, telomerase activity (TA) and alternative lengthening of telomeres (ALT), and to assess their prognostic relevance in diffuse malignant peritoneal mesothelioma (DMPM). EXPERIMENTAL DESIGN In 44 DMPM specimens obtained from 38 patients, TA was determined using the telomeric repeat amplificati...

Prokaryotic chromosomes code for toxin-antitoxin (TA) loci, often in multiple copies. In E.coli, experimental evidence indicates that TA loci are stress-response elements that help cells survive unfavorable growth conditions. The first gene in a TA operon codes for an antitoxin that combines with and neutralizes a regulatory 'toxin', encoded by the second gene. RelE and MazF toxins are regulato...

The aphase is rich in Ta. When the Ta concentration is less than 14%N, adoes not interfere with the slip mechanism; when the Ta concentration is more than 15%, ainterferes with the slip mechanism. The coherent at-Co 3Ta phase forms at Ta concentrations of less than 15%1, whereas incoherent 7-Co2Ta forms only at higher Ta concentrations. The interface between aand the matrix is an important fact...

Neotropical bats use torpor as a strategy to save energy when they experience a low energy intake and/or low ambient temperature (Ta). Digestive physiology limits the energy intake of several glossophaginid bats, and could play an important role in the onset of torpor in these tropical animals. We measured the effect that diet quality and Ta had on the use of torpor by the nectar-feeding bats G...

The Pi-ta gene in rice confers resistance to races of Magnaporthe oryzae that contain AVR-Pita. Pi-ta encodes a predicted cytoplasmic receptor protein with a nucleotide-binding site and a leucine-rich domain. A panel of 51 Oryza accessions of AA genome species Oryza sativa, O. glaberrima, O. rufipogon, O. nivara, and O. barthii, and CC genome species O. officinalis were sequenced to investigate...

Porous tantalum (Ta) implants are highly corrosion resistant and biocompatible, and they possess significantly better initial stability than that of conventional titanium (Ti) implants. During loading wear, Ta nanoparticles (Ta-NPs) that were deposited on the surface of a porous Ta implant are inevitably released and come into direct contact with peri-implant osteoblasts. The wear debris may in...

In this study, a novel coordination bonding system based on metal-tannic acid (TA) architecture on zein/carboxymethyl chitosan (CMCS) nanoparticles (NPs) was investigated for the pH-responsive drug delivery. CMCS has been reported to coat on zein NPs as delivery vehicles for drugs or nutrients in previous studies. The cleavage of either the "metal-TA" or "NH2-metal" coordination bonds resulted ...

[Purpose] The purpose of this study was to devise a new urinary incontinence exercise using co-contraction of both the transverse abdominal muscle (TA) and pelvic floor muscle (PFM) and examine the intervention effect in middle-aged women with stress urinary incontinence (SUI). [Subjects] The subjects were fifteen women with SUI who were divided into two groups: the TA and PFM co-contraction ex...
