Gross heating value of various shade-trees wood in coffee plantation in Costa Rica and its relation with extractives and specific gravity

open access: yesCoffee and Cocoa Research Journal, 2018
Shade-trees with energy use in coffee plantations are an important alternative to increase profitability in groforestry systems. The aim of this study was to investigate gross calorific value (GCV) of 15 shade-tree species in coffee plantations in Costa ...

Characterization of the gcv control region from Escherichia coli [PDF]

open access: yesJournal of Bacteriology, 1994
We constructed a set of deletions upstream of the gcv promoter and analyzed the effects of the deletions on expression of a gcvT-lacZ gene fusion. A deletion that ends at position -313 upstream of the transcription initiation site (+1) results in reduced levels of gcvT-lacZ expression, but the fusion is still inducible by glycine and repressible by ...

Neural differentiation of glioblastoma cell lines via a herpes simplex virus thymidine kinase/ganciclovir system driven by a glial fibrillary acidic protein promoter

open access: yesPLoS ONE, 2021
Glioblastoma is a malignant brain tumor with poor prognosis that rapidly acquires resistance to available clinical treatments. The herpes simplex virus thymidine kinase/ganciclovir (HSVtk/GCV) system produces the selective elimination of HSVtk-positive ...

Hipparcos Stars in The GCVS [PDF]

open access: yesHighlights of Astronomy, 1998
Prof. M. Grenon asked the team of the General Catalogue of Variable Stars to attribute GCVS names to new Hipparcos variables in order to present, in the Hipparcos Catalogue, the information on these stars already with final designations. We received lists of 5665 variables.

Nonparametric Spline Truncated Regression with Knot Point Selection Method Generalized Cross Validation and Unbiased Risk

open access: yesJTAM (Jurnal Teori dan Aplikasi Matematika), 2023
Nonparametric regression approaches are used when the shape of the regression curve between the response variable and the predictor variable is assumed to be unknown. Nonparametric excess regression has high flexibility.
