Relação potássio-nitrogênio para o diagnóstico e manejo nutricional da cultura da batata Nitrogen-potassium relationship for diagnosis of plant nutritional status and fertilization of the potato crop

open access: yesPesquisa Agropecuária Brasileira, 2006
O objetivo deste trabalho foi determinar a curva máxima de diluição do K e ajustar a relação com a curva de diluição do N, durante o ciclo de crescimento e desenvolvimento da batata, para fins de diagnóstico e manejo nutricional.

Effect of Track Overlap on the Microstructure and Properties of the CoCrMoSi PTA Coatings [PDF]

open access: yesMaterials Research, 2015
Broadly speaking, the research and design of coatings are generally studied by way of single-track deposits; otherwise, the development of a coated part entails the understanding of how multi-track welding influences the microstructure and properties of ...

A Cre‐dependent lentiviral vector for neuron subtype‐specific expression of large proteins

open access: yesFEBS Letters, EarlyView.
We designed a versatile and modular lentivector comprising a Cre‐dependent switch and self‐cleaving 2A peptide and tested it for co‐expression of GFP and a 2.8 kb gene of interest (GOI) in mouse cortical parvalbumin (PV+) interneurons and midbrain dopamine (TH+) neurons.

Heterophilic interference of rheumatoid factor in tsh immunometric assay: A cross-sectional observational study

open access: yesIndian Journal of Endocrinology and Metabolism
Introduction: Considering the inherent vulnerability of immunoassays for heterophilic interference and the potential of Rheumatoid Factor (RF) to act as a heterophile-like antibody, we conducted this study to investigate if RF leads to any such ...

The Fate of the Universe: Dark Energy Dilution? [PDF]

open access: yes, 2007
We study the possibility that dark energy decays in the future and the universe stops accelerating. The fact thatthe cosmological observations prefer an equation of state of dark energy smaller than -1 can be a signal that dark energy will decay in the ...

Hematopoietic (stem) cells—The elixir of life?

open access: yesFEBS Letters, EarlyView.
The aging of HSCs (hematopoietic stem cells) and the blood system leads to the decline of other organs. Rejuvenating aged HSCs improves the function of the blood system, slowing the aging of the heart, kidney, brain, and liver, and the occurrence of age‐related diseases.

Dilution of whisky – the molecular perspective

open access: yesScientific Reports, 2017
Whisky is distilled to around 70% alcohol by volume (vol-%) then diluted to about 40 vol-%, and often drunk after further slight dilution to enhance its taste.

Clamp-tapering increases the quality factor of stressed nanobeams

open access: yes, 2019
Stressed nanomechanical resonators are known to have exceptionally high quality factors ($Q$) due to the dilution of intrinsic dissipation by stress. Typically, the amount of dissipation dilution and thus the resonator $Q$ is limited by the high mode ...

Structural insights into lacto‐N‐biose I recognition by a family 32 carbohydrate‐binding module from Bifidobacterium bifidum

open access: yesFEBS Letters, EarlyView.
Bifidobacterium bifidum establishes symbiosis with infants by metabolizing lacto‐N‐biose I (LNB) from human milk oligosaccharides (HMOs). The extracellular multidomain enzyme LnbB drives this process, releasing LNB via its catalytic glycoside hydrolase family 20 (GH20) lacto‐N‐biosidase domain.

Response of Two Different Strains of Commercial Broilers to Different Dietary Amino Acid Allowance

open access: yesMedia Peternakan, 2009
The response of Cobb and Ingham strain commercial broilers to a range of dietary amino acids in a factorial experiment (2 strains x 2 sexes x 3 dietary treatments) with 3 replicates was evaluated. A total of 180 birds was sexed and weighed at one-day-old
