Most cinnamic acids, their esters, amides, aldehydes, and alcohols present several therapeutic actions through anti-inflammatory, antitumor, and inhibitory activity against a great variety of microorganisms. In this work, eight amines derived from cinnamic acid were synthesized and tested against host cells infected with Toxoplasma gondii and the bacteria Escherichia coli, Pseudomonas aeruginosa, Staphylococcus epidermidis, and three strains of Staphylococcus aureus. Compounds 3 and 4 showed the ...

This paper presents a method to electrically trim the resonance frequency of a silicon bulk acoustic resonator (SiBAR) after its fabrication is completed. The small volume of the microresonator can be Joule heated to a sufficiently high temperature to allow for diffusion of deposited metals from its surface onto its bulk. Such high temperatures also facilitate the formation of silicon-metal bonds which, depending on the metal, are either stronger or weaker compared to the existing silicon-silicon ...

The objective of this work was to evaluate the development of soursop (Annona muricata L.) seedlings inoculated with arbuscular mycorrhizal fungi (AMFs) cultivated with different doses of phosphorus (P). The experiment was carried out in a greenhouse with a completely randomized factorial design (4 x 4), with non inoculated plants (controls), three species of arbuscular mycorrhizal fungi, Glomus clarum, Gigaspora margarita and native AMFs (Glomus macrocarpum, G. etunicatum and Entrosphopora colombiana) ...

This paper demonstrates the dependence of temperature coefficient of frequency (TCF) of silicon micromechanical resonators on charge carrier concentration. TCF compensation is demonstrated by degenerate doping of silicon bulk acoustic resonators (SiBARs) using both boron and aluminum dopants. The native TCF of -33×ppm/ ° C for silicon resistivity of >; 10 3 Ω · is shown to reduce to -1.5×;ppm/ ° C at ultralow resistivity of ~10× -4 ;Ω·cm using relatively slow diffusion-based boron doping. However, the faster thermomigration- ...

Antimicrobial proteins have been isolated from a wide range of plant species. More recently, it has become increasingly clear that these types of proteins play an important role in the protection of plants. In this study, we investigate the presence of defense-related proteins from passion fruit (Passiflora edulis f. flavicarpa) seeds. Initially, seed flour was extracted for 2 h (at 4 °C) with phosphate buffer, pH 5.5. The precipitate obtained between 0 and 70% relative ammonium sulfate saturation ...

Staphylococci bacteria are involved in many human and animal infections and development of alternative antimicrobial drugs against pathogenic bacteria is of great interest to the pharmaceutical industry. This study investigated the in vitro effect of Rauvolfia grandiflora methanol extract (root bark fraction) (RGE) on the density of ATCC strains of Staphylococcus aureus and Staphylococcus epidermidis, and a clinical enterotoxin-producer, S. aureus bovine strain. The alkaloid, isoreserpiline, obtained ...

Small-scale fisheries (SSF, boats < 12 m) represent 90% of this sector at a worldwide scale and 84% of the EU fleet. Mapping the areas and intensity where the fishing operations occur is essential for spatial planning, safety, fisheries sustainability and biodiversity conservation. The EU is currently regulating position tracking of SSF fishing vessels requiring precision resolved geo-positional data (sec to min resolution). Here we developed a series of procedures aimed at categorizing fishing boats ...

The development of a silicon-only capacitive dew point sensor is described in this paper. The principle of operation is based on the change in capacitance of an interdigitated parallel plate capacitor due to the condensation of water below dew point temperature. The proposed sensor element is simple in fabrication, with only one lithography step and no metal or polymer usage. The experiments show good repeatability and baseline stability, whereas detection accuracy needs to be further improved. ...

Clayey ceramics are being traditionally fabricated in the municipal area of Campos dos Goytacazes, Rio de Janeiro, Brazil, by a mixture of different clays to attend the technical specifications. In several cases, the simple mixture of clays is not able to grantee the required properties for a given fired ceramic product. In the present work, distinct formulation using two types of clays, with or without the addition of ornamental stone waste, were investigated for the effect on the technical properties ...

This paper presents a silicon microfabrication technique for the implementation of large-value one-port and two-port tunable capacitors with very small tuning voltages. The proposed process offers very high aspect- ratio narrow vertical gaps of different sizes in a self- aligned manner, allowing the realization of in-plane tunable capacitors in a small area. A continuous tuning of 240% is achieved for a 15 pF two-port capacitor with the application of 3.5 V. A 106 pF one-port capacitor occupies ...

Gangliogliomas (GG) are rare primary central nervous system (CNS) tumors. These CNS tumors are more commonly located at the supratentorial level. The treatment of choice for these tumors is surgical resection, and the role of radiotherapy remains controversial. A 61-year-old woman who presented with seizures underwent a magnetic resonance imaging (MRI), which showed a left-side thalamic lesion with one solid and two cystic components. A neuronavigation-guided brain biopsy of the lesion established ...
