Treatment for the amelioration of persistent factors in complex anal fistula
(Springer, 2021-11-19)Anal fistulae are abnormal hollow connections between the wall of the anal canal and the perianal skin around the anus that have remained a burden on the medical sector for centuries. The complexity of this disease is ... -
Application of biomaterials for complex anal fistulae
(Taylor & Francis, 2021-11-07)Complex anal fistulae remain a challenge for the medical sector as conventional treatments put patients at risk of incontinence. Clinicians and researchers have become interested in the application of bioresorbable ... -
Evaluation of titanium nitride coatings in bandsaw blades for wood splitting by cold plasma
(Taylor & Francis, 2021-11-06)Due to the advances in surface treatments, it is possible to obtain excellent cutting tools. However, the field for wood cutting tools still needs to be further investigated. In this work, titanium nitride was deposited ... -
Upcycling biodegradable PVA/starch film to a bacterial biopigment and biopolymer
(MDPI, 2021-10-27)Meeting the challenge of circularity for plastics requires amenability to repurposing post-use, as equivalent or upcycled products. In a compelling advancement, complete circularity for a biodegradable polyvinyl ... -
Transfer and optimisation of injection moulding manufacture of medical devices using scientific moulding principles
(MDPI, 2021-10-25)Scientific moulding, also known as decoupled injection moulding, is a production methodology used to develop and determine robust moulding processes resilient to fluctuations caused by variation in temperature and viscosity. ... -
On the possibility of replacement of calcium carbonate by a high-performance, economically viable filler in polyethylene composites
(Sage, 2021-07-14)Calcium carbonate (CaCO3) is frequently added to polyethylene (PE) as a filler to reduce costs. An alternative to CaCO3, calcium fluoride (CaF2) was proposed in this research. PE/CaCO3 and PE/CaF2 composites in a wide ... -
Composite films of thermoplastic starch and CaC12 extracted from eggshells for extendiing food shelf-life
(MDPI, 2021-09-03)Calcium chloride (CaCl2) has been widely used to maintain the quality of fresh-cut fruits and vegetables because it stabilizes and strengthens the membrane system against fungal attacks. It is mainly applied via spray ... -
