    Compactação do solo e crescimento de plantas: como identificar, evitar e remediar.

    Get PDF
    A compactação do solo é um fenômeno conhecido e constitui tema de crescente importância demandando muita atenção por parte de produtores rurais, agrônomos da extensão rural, profissionais de vendas e assistência de tratores e implementos agrícolas e consultores. O solo compactado vem resultando na diminuição no crescimento das raízes em profundidade, predispondo a planta à morte em curtos períodos de seca, no acúmulo de água na superfície do solo impossibilitando a respiração das raízes e favorecendo o processo de erosão hídrica do solo. Esta publicação visa auxiliar, de modo sucinto, na identificação da compactação do solo, como evitar seu surgimento e como resolver o problema quando constatado.bitstream/CNPS/11604/1/doc56_2003_compactacao_solo.pd

    Brand gender and consumer-based brand equity on Facebook: The mediating role of consumer-brand engagement and brand love

    Get PDF
    Brand gender has been suggested as a relevant source of consumer-based brand equity (CBBE). The purpose of this paper is to deepen understanding of the relationship between brand gender and CBBE by analyzing the mediating roleofconsumer–brandengagement (CBE)andbrandlove(BL)onthisrelationship.Thisresearchwas conducted on Facebook, the dominant global social media platform. The hypotheses were tested using structural equation modeling. Results support 6 of the 9 hypotheses, with a significant relationship between analyzed constructs. This study advances prior work by showing that brand gender has an indirect and relevant impact on CBBE through BL and CBE. Therefore, this research confirms the advantages of clear gender positioning and extends prior research by suggesting that brands with a strong gender identity will encourage BL and CB

    Catching the Bound States in the Continuum of a Phantom Atom in Graphene

    We explore theoretically the formation of bound states in the continuum (BICs) in graphene hosting two collinear adatoms situated at different sides of the sheet and at the center of the hexagonal cell, where a phantom atom of a fictitious lattice emulates the six carbons of the cell. We verify that in this configuration the local density of states (LDOS) near the Dirac points exhibits two characteristic features: i) the cubic dependence on energy instead of the linear one for graphene as found in New J. Phys. 16, 013045 (2014) and ii) formation of BICs as aftermath of a Fano destructive interference assisted by the Coulomb correlations in the adatoms. For the geometry where adatoms are collinear to carbon atoms, we report absence of BICs
