The Coronavirus pandemic has brought the broadband gap in United States into stark relief-5.6 percent of population no access to infrastructure. But for an even larger percentage population, issue is that they can't afford access, or get by on mobile phone plans. Recent estimates, example, suggest 15 million 16 students-roughly 30 grade-school States-lack some reason.

Este estudo pretende realizar discussões iniciais sobre as possibilidades de utilização do conceito escala nas pesquisas educacionais, analisando, em especial, limitações e potencialidades das perspectivas microssocial macrossocial na formação professores. Os estudos atuais indicam que educacionais se utilizam uma perspectiva detrimento outra. Acredita-se apesar, dos diversos desafios ao tentar...

We present a multiscale micro-macro method for the Stokes problem in heterogeneous media. The macroscopic method discretizes a Darcy problem on a coarse mesh with permeability data recovered from solutions of Stokes problems around quadrature points. The accuracy of both the macro and the micro solvers is controlled by appropriately coupled a posteriori error indicators, while the total cost of...

This paper presents design aspects of a forcere ecting, motion-scaling teleoperation system for use in microsurgery experiments. A coarse-macro-micro approach is proposed. Two magnetically levitated wrists | a macro-master and a micro-slave | would share a common base positioned at the surgical site by a coarse-motion transport robot. The discussion includes features of the proposed system, a d...

Bulbous Allium spp. such as “big-headed” elephant garlic (Allium ampeloprasum L.) and common sativus contain a wide range of bioactive compounds with health-promoting properties are most commonly used food seasonings. The objective the present study is to verify if there difference in selected nutraceuticals (dry matter, TPC, allicin) elemental profiles (macro- micro-elements) two species produ...

Macro and micro-elements, carbon sources and elicitors play a central role during Panax ginseng hairy root growth, biomass and ginsenoside production and also influence numerous root developmental stages in largescale bioreactor culture. Due to the lack of biosynthetic nutrients and signalling-inducing nutrients, the regulatory role of mineral elements is not well understood. We have geneticall...
