An overview of vine water status assessment [PDF]

Ciência e Técnica Vitivinícola
In regions influenced by the Mediterranean climate, the distribution of rainfall is uneven throughout the year, with rainfall concentrated in winter and hot, dry summers, which is being boosted by climate change towards a worsening of this situation. Due

Water quality objectives as a management tool for sustainability [PDF]

, 1994
The aim of this paper is to explore the potential role that quality objectives, particularly when backed by statutory force, may play in the sustainable management of river water quality. Economic valuation techniques are discussed, as well as the theory

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

FEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Porosidade e retenção de água em um argissolo sob manejos convencional e direto submetido a compressões unidimensionais Porosity and water retention in an acrisol under conventional and no-till systems under uniaxial compression

Revista Brasileira de Ciência do Solo, 2008
A dinâmica da ocupação do espaço poroso pela água e ar em solos sujeitos ao estresse mecânico ainda é pouco conhecida, principalmente quando as pressões situam-se sobre a reta de pré-consolidação.

Continuous Monitoring of Plant Water Potential [PDF]

Plant Physiology, 1986
Plant water potential was monitored continuously with a Wescor HR-33T dewpoint hygrometer in conjunction with a L51 chamber. This commercial instrument was modified by replacing the AC-DC mains power converter with one stabilized by zener diode controlled transistors.

Potential for water distillation by using solar energy in Malawi [PDF]

, 2008
The potential for solar water distillation in Malawi has been modelled. Mean monthly global solar radiation (H) data from 19 sites spread all over the country was used to compute the mean monthly daily distillate productivity (M).

Aggressive prostate cancer is associated with pericyte dysfunction

Molecular Oncology, EarlyView.
Tumor‐produced TGF‐β drives pericyte dysfunction in prostate cancer. This dysfunction is characterized by downregulation of some canonical pericyte markers (i.e., DES, CSPG4, and ACTA2) while maintaining the expression of others (i.e., PDGFRB, NOTCH3, and RGS5).

Stomatal Conductance and Morphology of Arbuscular Mycorrhizal Wheat Plants Response to Elevated CO2 and NaCl Stress

Frontiers in Plant Science, 2018
Stomata play a critical role in the regulation of gas exchange between the interior of the leaf and the exterior environment and are affected by environmental and endogenous stimuli.

Dual targeting of RET and SRC synergizes in RET fusion‐positive cancer cells

Molecular Oncology, EarlyView.
Despite the strong activity of selective RET tyrosine kinase inhibitors (TKIs), resistance of RET fusion‐positive (RET+) lung cancer and thyroid cancer frequently occurs and is mainly driven by RET‐independent bypass mechanisms. Son et al. show that SRC TKIs significantly inhibit PAK and AKT survival signaling and enhance the efficacy of RET TKIs in ...
