Radio frequency (RF) energy transfer and harvesting has been intensively studied recently as a promising approach to significantly extend the lifetime of energy-constrained wireless networks. This technique has a great potential to provide relatively stable and continuous RF energy to devices wirelessly, it thus opened a new research paradigm, termed wireless-powered communication (WPC), which ...

In this work, two different technologies (electrospraying and nanospray drying) were evaluated for the encapsulation of folic acid using both a whey protein concentrate (WPC) matrix and a commercial resistant starch. The morphology of the capsules, molecular organization of the matrices upon encapsulation, encapsulation efficiency, and stability of the folic acid within the capsules under diffe...

Effects of pH and heating on deamidation whey protein concentrate (WPC) solution functional properties resultant spray-dried WPC powder were investigated. Temperature time affected rates with the highest reactivities for solutions heated at 120 °C 15 min 145 s. Deamidation sites dependent: 3 induced more glutamine deamidation; 10 asparagine deamidation. The powders also dependent. adjusted to s...

The objective of this work was to conduct an ontogenetic and structural study of the urachus. We studied 40 human fetuses (13-20 weeks post conception, WPC). The urachus was stained in Masson's trichrome, to quantify connective tissue and smooth muscle and to determine the urachal lumen area. Weigert's resorcin-fuchsin was used to observe elastic fibers, and picrosirius red and immunohistochemi...

This study evaluated the mechanical and hydrophobic properties of wood plastic composites (WPC) prepared by hot molding approach incorporating five different recycled plastics poplar flour. The WPC showed excellent tensile strength (36.9 MPa) flexural (44.7 associated with good hydrophobicity, could be due to application pressing which improved amount hydroxyl groups reduced crystallinity WPC. ...

Background Protein intake is essential to maximally stimulate muscle protein synthesis, and the amino acid leucine seems to possess a superior effect on muscle protein synthesis compared to other amino acids. Native whey has higher leucine content and thus a potentially greater anabolic effect on muscle than regular whey (WPC-80). This study compared the acute anabolic effects of ingesting 2 × ...

Whey proteins can be used as hydrogels and nanoparticle systems for encapsulation and controlled delivery of bioactive compounds. Whey protein concentrate (WPC) hydrogels exhibited pH-sensitive swelling behavior with minimum swelling ratio near the isoelectric point (pI) of whey proteins ( 5.1). The controlled drug release behavior of WPC hydrogels was studied using caffeine as a model drug. Co...

Background Supplemental protein sources vary in composition in regards to size, structure, and amino acid composition of the varying individual proteins. Serum albumin concentrate (SA) is a new protein source extracted from edible-grade bovine plasma, which was recently made available on commercial scale. As compared to the low MW proteins in whey protein concentrate (WPC), SA consists of highe...

today, by increase in production capacity of dairy manufactures, high amounts of whey is produced as a by product of cheese production. in recent decays, high amount of whey production sometimes up to 8 times more than produced cheese-, its high bod and its environmental problems caused in particular attention to whey processing and its usage in food products. according to promotions occurred i...
