Abstract At the conclusion of road construction projects, an erosion control product (e.g., blankets, spray mulch) is installed to reduce soil loss and promote plant growth. Wildlife, such as snakes (suborder Serpentes), are prone to entanglement in erosion control blankets (ECBs) that contain polypropylene mesh with fused apertures. Previous reports have noted that the occurrences of entanglements are not uniform in their distribution across an ECB, but primarily occur where the edge of the mesh is exposed. We conducted an experiment to determine if modification to the installation methods of ECBs affects the likelihood of snake entanglement. We conducted entanglement trials to compare the likelihood of snake entanglement between two treatments: 1) exposed ECB edge (i.e., perimeter) and 2) buried ECB edge. Snakes were less likely to attempt to pass through the mesh on the buried edge treatment and all entanglements occurred on the exposed edge treatment. These results provide support that modification to the installation methods reduces snake entanglement in ECBs in some settings. However, we conducted our study in an experimental setting, and it should be evaluated under natural field conditions. This research can be used to inform several parties including contractors, habitat managers, and agency decision makers on additional steps that can be taken for products that fit their application needs to minimize risks to wildlife.

Theory and principles of rheology can be used for, process control, product design and as a tool for prediction process if the process could not actually be measured. The purpose of this research is to find rheological properties of margarine in dough/non-newtonian fluid developed on two parallel flat acrylic separated by an infinitesimally small gap. The driving force of the development fluid is CO2 fermented yeast. Fluid driven and expands passed a small gap in various sizes. Development time and time to pass through the small gap measured. The samples are used are two, dough without addition of margarine and other. Experiments showed that fluid added by margarine would be easier to pass through small gap than other, characterized by shorter time to pass through the small gap.

Since the early 1980s willow and poplar trees originally planted for erosion control have been cut and fed to hungry livestock during droughts, with impressive results. This involves shaping trees by cutting them to develop an operating "nest" that enables the farmer to prune regrown branches with greater safety, provided forestry training has been undertaken. More recently, trees have been planted specifically to grow supplementary fodder and some types have performed better than others. The concept is, in our opinion, quite cost-effective and the benefits of growing these trees far outweigh any drawbacks.

Circular Economy is a means to ensure sustainable production and consumption patterns. However, it is still at an embryonic stage of implementation in manufacturing companies. Given its potential, the household appliance industry is a promising arena for the adoption of Circular Economy. Thus, this study aims to investigate and systematize how Circular Economy has been adopted in the household appliance industry, through a multiple case study research. Twenty cases are analyzed following a Research Framework, to map: (i) the Circular Economy 4R strategies of reduce, reuse, remanufacture and recycle; (ii) the Circular Economy levers, i.e., whether circular product design practices, servitized business models or supply chain management actions are undertaken; (iii) the role of digital 4.0 technologies as enablers; (iv) the benefits achieved. The analysis showed that servitized business models and supply chain management actions are widely used levers, while little attention is devoted to circular product design practices. Internet of Things (IoT), Big Data and Cloud emerged as powerful enablers of servitized business models. Two main patterns of Circular Economy adoption in the household appliance industry emerged from cases: incremental and radical adoption patterns. Incremental adoption patterns are based on design strategies focused on reduce and recycle, mainly led by manufacturers. Radical adoption patterns are instead focused on disruptive practices based on reuse, remanufacture, servitization and sharing, where digital 4.0 technologies serve as enablers. Overall, this exploratory research lays the foundation for a stronger and more systemic understanding of the adoption of Circular Economy in the household appliance industry.
