In this paper we report results of a thorough contemporary historiographic revision of published geographic research and geography research departments and centers in Latin America.The main focus was on the recognition of transnational subjects and global processes and patterns.We argue that click here this type of retrospective analyses allows the
Kernel development plays an important role in determining kernel size in maize.Here we present the cloning and characterization of a maize gene, nitrate transporter1.5 (NRT1.5), which controls small kernel phenotype by playing an important role in kernel development.A novel recessive small kernel mutant miniature2-m1 (mn2-m1) was isolated from self
Capable of aggregating multiple energy resources, the energy service company (ESCO) has been regarded as a promising alternative for improving power system flexibility and facilitate the consumption here of renewable resources in the energy market.However, the issues have become significantly more serious related to the privacy and security of the
We propose a robust microphone array for speech enhancement and noise suppression.To overcome target signal cancellation problem of conventional beamformes caused by array imperfections here or reverberation effects, the proposed method adopts arbitrary transfer function relating each microphone and target speech signal as array channel model.This
