Summary: This study investigates the synergistic effect of plasma-activated water (PAW) combined with twin-screw extrusion (TSE) on the structure, properties, and digestibility of yam starch (YS). The results show that PAW-TSE increases the amylose content, crystallinity, ordered degree, and gelatinization enthalpy of YS. It also improves the gel strength, thermal stability, and resistant starch content. The impact of PAW-TSE on YS is enhanced with longer preparation time of PAW.

Summary: Starch/PVA degradable straws with different PVA contents were prepared using the twin-screw extrusion method. The straws with 40% PVA exhibited the highest dispersion uniformity and molecular interactions, resulting in improved mechanical properties and water resistance. Compared to the straws without PVA, the swelling volume of the 40% PVA straws decreased significantly, and the diameter strength and water absorption were greatly increased.

Summary: This study investigated the impact of soluble soybean polysaccharide (SSPS) on the cooking and eating quality of rice noodles. The addition of SSPS improved the cooking and sensory quality of rice noodles, and rice noodles prepared by twin-screw extrusion had a more desired appearance and better taste. The addition of SSPS reduced the pasting viscosity of rice flour and inhibited the generation of the starch-ordered structure. Double-3% rice noodles exhibited higher cooking and eating quality, as well as intensity of V-type diffraction peak.

Summary: PP nanocomposites with MWCNT and/or CNF, fabricated by melt mixing, show enhancements in hardness, elastic modulus, and strength, with slow degradation in PEMFC environments. Based on the results, PP/20MWCNT, PP/21.5MWCNT, and PP/15MWCNT/15CNF nanocomposites are ideal choices for producing bipolar plates for PEMFCs.

Summary: This study provides insights into the precopulatory mating behavior of the papaya fruit fly, Anastrepha curvicauda, and how intrasexual selection affects mate selection. Dominant males were significantly preferred by females in choice experiments, and the presence of rival males altered courting behavior and led to agonistic interactions among males before and during mating.

Summary: The steady torsional parallel-plate flow of a viscoplastic microgel with apparent slip was analyzed using simultaneous rheometrical and particle image velocimetry (rheo-PIV) measurements. The velocity distributions of the microgel were found to be linear across the gap, except at the edge where non-linear flow occurred. The slip yield stress and slip velocity beyond this stress were calculated, and various methodologies were used to determine the yield stress of the microgel. The validity of the Mooney and Yoshimura and Prud'homme analyses in characterizing yield-stress fluids was confirmed.

Summary: This study analyzed the tribological and rheological behavior of mineral oil additivated with graphene nano-sheets as a lubricant, focusing on its potential application in automatic transmission systems. The addition of graphene nano-sheets made the lubricants non-Newtonian shear-thinning, increased viscosity at high shear rates, reduced wear rate for metallic interfaces, and enhanced the thermal stability and anti-shudder property of wet clutches.

Summary: Bacteria of the genera Xenorhabdus and Photorhabdus show differences in their pathogenicity and virulence mechanisms. Pangenome analysis revealed that Photorhabdus has a higher number of genes associated with pathogenicity. However, biological tests demonstrated that Xenorhabdus cells were more virulent than Photorhabdus cells when injected into G. mellonella larvae.

Summary: It has been discovered that the steady fractal vane-in-cup (fVIC) flow of complex fluids using vanes with fractal cross sections can produce an almost axisymmetric flow field and rotation rate-independent effective radius, making it a reliable measurement tool for complex fluids. However, axial shearing/compression during the insertion of the rheometric tool in the sample also accelerates syneresis, leading to shear banding for Couette and fVIC flows.

Summary: Mating is the process of males and females searching for potential reproductive partners. It is often believed that males prefer virgin, young, and large females, while females prefer virgin, young, and large males. However, this statement is not always true, and there are exceptions in nature. Understanding the attributes selected by each gender is important for population management and species evolution.

Summary: This study evaluated the effects of lactose-free milk as a culture medium and the addition of various carbon sources on the biomass production of Lactobacillus kefiranofaciens and Saccharomyces cerevisiae. The addition of 6% w/w agave fructans stimulated biomass growth and increased the content of fat, ash and protein. Furthermore, the absence of lactose resulted in significant changes in microbial diversity.

Summary: This study aimed to encapsulate Saccharomyces boulardii using agavins and whey protein as wall materials through ionic gelation, and evaluate the morphostructural changes during in vitro gastrointestinal digestion. The results showed that the encapsulated sample with 5% agavins and 3.75% whey protein had a cell survival rate of 88.5% after simulated digestion, with significantly different microstructure compared to the controls. The mixture of agavins and whey protein improved the survival of S. boulardii compared to encapsulation with alginate, agavins or whey protein alone.
