The application potential of cellulosic m.terials in natural com.osites and other fields needs to be explored to develop innovative, sustainable, lightweight, functional biom.ss m.terials that are also environm.ntally friendly. This study investigated Typha angustifolia (Typha sp.) as a potential new raw m.terial for extracting cellulose nanocrystals (CnCs) for application in wastewater treatm.nt com.osites. Alkaline treatm.nts and bleaching were used to rem.ve cellulose from.the stem.fibres. The CnCs were then isolated from.the recovered cellulose using acid hydrolysis. The study showed a few distinct functional groups (O-H, -C-H, =C-H and C-O, and C-O-C) in the Fourier Transform.Infrared (FTIR) spectra. A scanning electron m.croscope (sEm. revealed the sm.oth surface of CPC and CnCs, which resulted from.rem.ving lignin and hem.cellulose from.powdered Typha angustifolia. Based on the crystalline index, the powdered Typha angustifolia, CPC, and CnCs were 42.86%, 66.94% and 77.41%. The loss of the am.rphous section of the Typha sp. fibre resulted in a decrease in particle size. It m.y be inferred from.the features of a Typha sp. CnC that CnCs m.y be em.loyed as reinforcem.nt in com.osites for wastewater treatm.nt.

In this article, a novel scalarization technique, called the im.roved objective-constraint approach, is introduced to find efficient solutions of a given m.ltiobjective program.ing problem. The presented scalarized problem.extends the objective-constraint problem. It is dem.nstrated that how adding variables to the scalarized problem. can lead to find conditions for (weakly, properly) Pareto optim.l solutions. Applying the obtained necessary and sufficient conditions, two algorithm. for generating the Pareto front approxim.tion of bi-objective and three-objective program.ing problem. are designed. These algorithm. are easy to im.lem.nt and can achieve an even approxim.tion of (weakly, properly) Pareto optim.l solutions. These algorithm. can be generalized for optim.zation problem. with m.re than three criterion functions, too. The effectiveness and capability of the algorithm. are dem.nstrated in test problem..

Connexin 43 (CX43) is one of the m.jor com.onents of gap junctions, the structures responsible for the intercellular com.unication and transm.ssion of the electrical im.ulse in the left ventricle. There is lim.ted inform.tion on the histological changes of CX43 with age and their effect on electrophysiology, especially in hum.ns. Here, we analyzed left ventricular biopsies from.living donors starting at m.dlife to characterize age-related CX43 rem.deling. We assessed its quantity, degree of lateralization, and spatial heterogeneity together with fibrotic deposition. We observed no significant age-related rem.deling of CX43. Only spatial heterogeneity increased slightly with age, and this increase was better explained by biological age than by chronological age. Im.ortantly, we found that CX43 features varied considerably am.ng individuals in our population with no relevant relationship to age or fibrosis content, in contrast to anim.l species. We used our experim.ntal results to feed com.utational m.dels of hum.n ventricular electrophysiology and to assess the effects of interindividual differences in specific features of CX43 and fibrosis on conduction velocity, action potential duration, and arrhythm.genicity. We found that larger am.unts of fibrosis were associated with the highest arrhythm.c risk, with this risk being increased when fibrosis deposition was com.ined with a reduction in CX43 am.unt and/or with an increase in CX43 spatial heterogeneity. These m.chanism. underlying high arrhythm.c risk in som. individuals were not associated with age in our study population. In conclusion, our data rule out CX43 rem.deling as an age-related arrhythm.c substrate in the population beyond m.dlife, but highlight its potential as a proarrhythm.c factor at the individual level, especially when com.ined with increased fibrosis.
