Fragmentation–Coagulation Processes With Advection or Diffusion in Space

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this paper, we consider a continuous fragmentation–coagulation model in which the reacting particles can be transported in physical space through either advection or diffusion. We prove new results on the generation of C0$$ {C}_0 $$‐semigroups with parameter and use them to show that the abstract Cauchy problem associated with a more ...

Composite Fibers of Hydroxypropyl Cellulose and Alginate Spun From Aqueous Solution: Crosslinking Effects on Water Absorption and Mechanical Properties

open access: yesPolymer Engineering &Science, EarlyView.
Alginate‐HPC composite fibers spun via CaCl2‐induced gelation process. Fiber diameter ranges from 100 to 200 μm after air drying. Higher alginate boosts water absorption in dried fibers. HPC selectively diffuses out when fibers are soaked in water. Crosslinking with hexamethylene diisocyanate improves mechanical strength.

The Long Trajectory of Rubber Physics: 3500+ Years and Counting

open access: yesJournal of Polymer Science, EarlyView.
Natural rubber's trajectory is traced from Mesoamerican use of Castilla elastica through vulcanization and the pneumatic tire to macromolecular physics and modern solid‐state refrigeration. Illustrations of C. elastica and an H. brasiliensis plantation frame the historical progression from indigenous material, then industrial crop and on to advanced ...

Evaluation of buttermilk purification stage using an organic tannin-based coagulante

open access: yesOBSERVATÓRIO DE LA ECONOMÍA LATINOAMERICANA
With a growing estimate for the production of milk and dairy products for the next decade, Brazil has great potential in this sector. However, the large amount of effluents generated must be taken into account, and therefore, the most appropriate way of treating them. Buttermilk is the main by-product of butter processing, it has high nutritional value

Mating history shapes Wolbachia‐induced cytoplasmic incompatibility and female fitness in an insect pest

open access: yesPest Management Science, EarlyView.
Mating order and remating of females by males with different endosymbiont associations strongly shape Wolbachia‐induced cytoplasmic incompatibility, female fitness and offspring sex ratio. An incompatible first mating was weakly affected if followed by a compatible mating and vice versa, indicating strong first‐male sperm precedence with consequences ...

Estudio comparativo de un coagulante natural frente a coagulantes químicos

open access: yes, 2016
La escasez del agua es un problema global. Uno de los principales problemas en la industria textil es la eliminación de color de los efluentes residuales, así como la alta concentración de sal residual en estos efluentes. Los colorantes reactivos que son los más empleados en este mercado son responsables en gran parte de este problema debido a su gran ...

Protective Potentials of Natural Products Against Vascular Dementia: A Comprehensive Review of Experimental Studies

open access: yesPhytotherapy Research, EarlyView.
ABSTRACT Vascular dementia (VaD), accounting for up to 20% of dementia cases globally, is primarily driven by chronic cerebral hypoperfusion (CCH), which leads to progressive cognitive impairment. Despite the increasing prevalence of VaD, effective treatments remain limited.
