Aims The material and design of knee components can have a considerable effect on the contact characteristics of the tibial post. This study aimed to analyze the stress distribution on the tibial post when using different grades of polyethylene for the tibial inserts. In addition, the contact properties of fixed-bearing and mobile-bearing inserts were evaluated. Methods Three different grades of polyethylene were compared in this study; conventional ultra high molecular weight polyethylene (UHMWPE), highly cross-linked polyethylene (HXLPE), and vitamin E-stabilized polyethylene (VEPE).

The purpose of this study was to compare complication rates after total ankle replacement in 2 groups of patients based on polyethylene insert size. The total cohort was divided into 2 groups based on insert size. Group 1 included patients with polyethylene insert size less than 10 mm in thickness. Group 2 included patients with polyethylene insert sizes 10 mm and larger. Available charts were reviewed for patients who underwent primary total ankle arthroplasty by one surgeon.

Objectives Unicompartmental knee arthroplasty (UKA) is an alternative to total knee arthroplasty with isolated medial or lateral compartment osteoarthritis. However, polyethylene wear can significantly reduce the lifespan of UKA. Different bearing designs and materials for UKA have been developed to change the rate of polyethylene wear. Therefore, the objective of this study is to investigate the effect of insert conformity and material on the predicted wear in mobile-bearing UKA using a previously developed computational wear method.

Insects while feeding, encounter a wide array of hydrocarbon polymers in their diet and the digestive tracts of various insects contain microbial symbionts that aid in the degradation of these polymers. Thus the idea of insects as synthetic polymer bio-degraders was established. Soon various insect, like mealworms, flour beetles, weevils, wax moths etc. particularly from the Coleopteran and Lepidopteran orders, were identified to have remarkable abilities to consume and degrade a wide range of synthetic polymers like polyethylene, polyurethane, polypropylene, polystyrene and polyvinyl chloride into lower molecular weight, simple, and nontoxic molecules which are eventually excreted as fecula. In this review we aim at congregating the diversity of polymer degrading insect fauna and understanding the underlying mechanism in which the insect’s digestive enzymes works in synergy with the gut microbiota to digest complex synthetic polymers.

As the population of India is continuously rising we have to adopt certain ways of sustaining our agricultural growth and it can be achieved through conservation farming. Mulching has many strategic effects on soil ecosystem, crop growth and climate. It has become an important practice in modern crop production due to benefits such as reduced weed competition, moisture conservation, decrease in certain insect pests, improved yields of crops and more efficient use of soil nutrients. The most common mulching material is plastic, especially black polyethylene, which is used almost everywhere because of its low cost and production-proven benefits. Biodegradable films are also becoming more popular in fieldbecause they can be left there safely after harvesting but are less durable and cost much more than plastics. Generalizations are difficult to make because different mulching materials have been employed for various agricultural and horticultural species in various climatic situations. Results vary depending on the chosen strategy, growth techniques, environmental factors, and species
