Preferential trading in agriculture: New insights from a structural gravity analysis and machine learning

American Journal of Agricultural Economics, EarlyView.
Abstract Preferential trade agreements (PTAs) contain various non‐tariff provisions, yet identifying their trade effects remains challenging because these commitments are high‐dimensional and strongly correlated within agreements. We estimated a theory‐consistent structural gravity model with domestic flows for 26 agricultural subsectors over 1988–2017

Stability and usage of nitrogen in fats and oils

Grasas y Aceites, 1998
The oxidative rancidity is, without a doubt, the main cause of the deterioration of fats and oils, and defines the shelf life of this type of products. Therefore, the stability (resistance against oxidation) has come to be one of the factors which worry ...

Novel application of silica materials to reduce phenolic content of red wines

Applied Food Research
Phenolic compounds are responsible for the most critical attributes of red wine quality. Structural changes at the molecular level influence the ability of phenolics to contribute to the colour, astringency, and bitterness of the wines.

Preparation of MOEAMCl and MAAm Based Hydrogels and Effective Use in Anionic Dye Adsorption

Journal of Applied Polymer Science, Volume 142, Issue 16, April 20, 2025.
ABSTRACT In this study, hydrogels based on [2‐(Methacryloyloxy)ethyl]trimethylammonium chloride (MOEAMCl) and methacrylamide (MAAm) were synthesized for the removal of anionic dyes from aqueous solutions. Following detailed characterization, the use of hydrogels for methyl orange (MO) adsorption was investigated.

Physicochemical Properties and In Vitro Antioxidant Activity Characterization of Protein Hydrolysates Obtained from Pumpkin Seeds Using Conventional and Ultrasound-Assisted Enzymatic Hydrolysis

Foods
Pumpkin seed proteins (PSPs) are a promising resource for obtaining bioactive peptides but their low solubility hinders enzymatic hydrolysis, reducing yield and bioactivity. In addition, enzymatic processes require specific conditions and long processing

Synergistic Integration of LiCF3SO3 in PVdF‐HFP/PVAc Polymer Blends: Multifaceted Analysis From Microstructure to Electrochemical Properties

Journal of Applied Polymer Science, EarlyView.
Solid polymer electrolyte films of PVdF‐HFP/PVAc blend with LiCF3SO3 were prepared by solution casting. XRD, FESEM, and FTIR confirmed reduced crystallinity and enhanced amorphous nature. Ionic conductivity reached 3.46 × 10−4 S cm−1 for optimized SP4.

Tips and Tricks for Hardware Removal and Allograft Fixation After a Failed Latarjet Procedure

Arthroscopy Techniques, EarlyView.
Abstract Although relatively rare, recurrent anterior shoulder instability requiring revision surgery after a failed Latarjet procedure can result in complications such as graft malposition, graft osteolysis, broken hardware and/or infection. Revision surgery after a failed Latarjet is a challenge due to a combination of technical factors such as ...

Soaking Water Management Strategies for Enhanced Quality of Parboiled Rice

Cereal Chemistry, EarlyView.
ABSTRACT Background and Objectives Parboiling is a hydrothermal process that alters rice physicochemical and nutritional properties. The soaking step is crucial, influencing off‐flavor formation, mineral retention, and effluent quality. This study evaluated five soaking water (SW) management strategies combining different frequencies and volumes of SW ...

Tetradecanuclear {Ni9Ln5} Clusters Featuring Encapsulated {Ln5} Trigonal Bipyramids: Modular 3d‐4f Architectures With Broad‐Range Magnetocaloric Response

Chemistry – A European Journal, EarlyView.
The use of 2‐aminoisobutyric acid in 3d–4f chemistry affords three {Ni₉Ln5} clusters, with the Gd analogue exhibiting an unusually broad magnetocaloric effect across an extended temperature range. ABSTRACT The solvothermal reaction between Ni(HCOO)2.2H2O, 2‐aminoisobutyric acid (aibH), Ln(OAc)3·4H2O (Ln = Gd, Y, Dy) and NEt3 in MeOH/MeCN affords the ...
