Technical and nutritional implications of trans fatty acids in hydrogenated oils
Grasas y Aceites, 1993 Customers are increasingly paying attention to fats and oils because they are strongly health related. Many points are still confusing about this, but certainly there is one that will soon become public concern: the presence of trans fatty acids in ...

Circulant Matrix‐Based Box–Behnken Designs With Economic Run Sizes
Quality and Reliability Engineering International, EarlyView.ABSTRACT We introduce Circulant Matrix‐Based Box–Behnken Designs (CBBDs), a new class of three‐level, second‐order response surface designs constructed using circulant matrix structures. These designs satisfy an enhanced orthogonal minimally aliased (OMA∗${\rm OMA}^*$) property: they retain the classical OMA property—where main effects are orthogonal ...

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 ...

Journal of Applied Polymer Science, Volume 143, Issue 27, July 15, 2026.Optimized potential of rCB via DOE: recovered carbon black from end‐of‐life tires was assessed as a full substitute for conventional carbon black in IIR composites. DOE and response surface methodology optimized rCB loading, plasticizer, and sulfur contents. Hardness showed linear trends, while rupture energy was nonlinear.
