A β-SiH functionalized benzyl anion [C(SiHMe2)2Ph]- is obtained by deprotonation of HC(SiHMe2)2Ph with KCH2Ph or by reaction of KOtBu and (Me2HSi)3CPh; LnI3(THF)n and three equivalents of this carbanion combine to provide homoleptic tris(alkyl)lanthanide compounds Ln{C(SiHMe2)2Ph}3 (Ln = La, Ce, Pr, Nd) containing secondary metal-ligand interactions.

OBJECTIVE To analyze underreporting of deaths and hospital admissions from tuberculosis to the Information System for Notifiable Diseases (SINAN). METHODS Cases with tuberculosis as basic or associated cause of death were selected from the Brazilian Mortality Information System (SIM) and hospital admissions for tuberculosis as main or secondary cause from the Hospital Information System of th...

Hemorrhage Growth To the Editor: I read with great interest the article by Mayer reviewing ultra-early hemostatic therapy for intracerebral hemorrhage (ICH).1 Prospective and retrospective studies had confirmed that ICH growth is a common phenomenon, especially within the first 6 hours of onset. Moreover, hematoma volume has been identified as the single most powerful predictor of 30-day mortal...

Resource distributions may be important for spatial use in animals. There appears to be a negative relationship between resource quality or density and home range size (McNab 1963; e.g. Dussault et al. 2005), and moreover, the distribution of resources within a home range may also affect its overall shape (Mitchell & Powell 2004). All else equal, the more resources that are available, the less ...

%'e have applied the Schwinger multichannel formulation [K. Takatsuka and V. McKoy, Phys. Rev. A 24, 2473 (1981)]to the elastic scattering of low-energy (1—30-eV) electrons by silane. Our results, obtained within the fixed-nuclei, static-exchange approximation, are in generally good agreement with recent differential, integral, and momentum-transfer cross-section measurements between 5 and 30 e...

-Si atomic layer growth on Si was investigated by heating the surface with a Xe flash lamp in an ultraclean low-pressure environment of SiH, or Si2H6 gas. In the case of SiH4, about 0.4 atomic layer deposition per single flash light shot was observed on Si(1OO) at a substrate temperature of 385OC and at a SiH, partial pressure of 500Pa. The adsorption process of SiH, can be explained quantitati...

Objetivo: avaliar agressões físicas contra mulheres, ocorridas em Minas Gerais 2018 e no contexto da pandemia de COVID-19 (internações entre março a agosto 2019/2020).
