Pengaruh komposisi perekat tanin urea formaldehida terhadap keteguhan rekat kayu lapis meranti

open access: yesJurnal Penelitian Hasil Hutan (Journal of Forest Products Research), 2017
Based on previous  research  tannin formaldehyde  resin from  Acacia   decurens     bark can  be used for  exterior plywood adhesive.  To reduce  the cost,   the effect of urea addition  to produce tannin   urea formaldeliyde   resin has been  studied.

The Origin of Life [PDF]

open access: yes, 1974
The origin of life is in a sense a genetic problem, for, as H. J. Muller pointed out many years ago, the essential attribute that identifies living matter is its capacity to replicate itself and its variants (1). Because this uniquely biological property

Natural Variation of NAR5 Determines Nitrogenase Activity and the Yield in Soybean

open access: yesAdvanced Science, EarlyView.
This study identified NAR5, a gene encoding a subtilisin‐like protease, that regulates nitrogenase activity in soybean nodules. Overexpressing NAR5 delayed nodule senescence, enhancing nitrogenase activity, yield, and low‐nitrogen tolerance. The elite haplotype NAR5HapI‐1 linked to superior nitrogenase activity and greater seed weight has been ...

Production and Properties of Isocyanate-Bonded MDF Manufactured from Acacia Mangium [PDF]

open access: yes, 1990
Medium density fiberboards (MDF) were manufactured from fast-growing Acacia mangium wood. The boards were produced at two levels of density, 600 and 750 kg/m³. Isocyanate and urea- formaldehyde resin adhesives were used asbinders.

The HLA-E Gene encodes two differentially regulated Transcripts and a Cell Surface Protein [PDF]

open access: yes, 1992
An HLA-E-specific oligonucleotide probe was used to study the expressioonf HLA-E. This probed etects two HLA-E transcripts, 1.8 and 2.7 kb in size, which are present in varying ratios in allt issues and cell lines investigated.

Directed Evolution Improves the Catalytic Efficiency of APEX2‐Mediated Proximity‐Dependent RNA Labeling

open access: yesAdvanced Science, EarlyView.
ABSTRACT Engineered ascorbate peroxidase APEX2 has been widely used for spatially restricted profiling of subcellular biomolecules, but its catalytic efficiency toward newly developed probes such as biotin‐aniline (Btn‐An) remains suboptimal. To overcome this limitation, we performed yeast surface display‐based directed evolution to enhance APEX2 ...

Self-healing composites: A review [PDF]

open access: yes, 2015
Self-healing composites are composite materials capable of automatic recovery when damaged. They are inspired by biological systems such as the human skin which are naturally able to heal themselves.

Rational Design of Broad‐Spectrum Anti‐Enteroviral Molecular Glues Targeting Enteroviral RNAi Suppressors

open access: yesAdvanced Science, EarlyView.
By leveraging this homodimerization mechanism, molecular glues were rationally designed to induce dysfunctional 3A dimerization, thereby restoring antiviral RNAi. The optimal molecular glue, VTP‐32, demonstrated potent and pan‐enterovirus (groups A, B, D) antiviral effects.

PROPERTIES OF WOOD AND RICE HUSK PARTICLEBOARD IN DIFFERENT PROPORTIONS

open access: yesCiência Florestal, 2010
This work aimed at evaluating the quality of particleboard manufactured with different wood proportions (Eucalyptus grandis) and rice husk. The composites were produced in the proportions 0, 20, 40, 60, 80, and 100% of rice husk with the use of urea ...

T Cell‐Independent Role of PD‐L1 in Kidney Repair: Mitigation of Tubular DNA Damage via PD‐L1/BRCA1 Interaction Following AKI

open access: yesAdvanced Science, EarlyView.
PD‐L1 is primarily expressed in renal tubules and upregulated in both murine models of AKI and renal biopsy samples from patients with AKI. PD‐L1 can promote adaptive TECs repair through interacting with BRCA1, independent of its canonical immunomodulatory function of T cells, and PD‐L1 supplementation may represent a promising therapeutic strategy for
