This paper reports the fabrication and characterization of fully-integrated, fully-batch-microfabricated electromagnetic vibrational energy harvesters. The 4 – 15 mm structures utilize embedded NdFeB powder micromagnet technology, and represent some of the smallest magnetic energy harvesters demonstrated to date. Of three different designs, the best performing demonstrated 13.2 μVrms at the dev...

Recent portable electronic devices have strict requirements regarding size, weight, and power. The power needed directly impacts the size of the required batteries, and larger batteries compromise the sizes and weights of portable devices. In order to design successful portable devices that maximize power and minimize size, devices should be operated in lowpower-consuming or self-powered mode. ...

The paper introduces the notion of “entropy harvesting” in physical and biological systems. Various physical and natural systems demonstrate the ability to decrease entropy under external stimuli. These systems, including stretched synthetic polymers, muscles, osmotic membranes and suspensions containing small hydrophobic particles, are called “entropic harvesters”. Entropic force acting in the...

Total Allowable Catch (TAC)-regulating schemes have been introduced in most fisheries. TAC distribution following the Proportional Rule, based on historical catches, implies that harvesters or vessel groups that have captured more in the past and contributed to overfishing are getting larger quotas than groups that have contributed less to overfishing. In contrast to this rule, a more egalitari...

Forage harvesters in modern design are powerful machines that ensure the harvesting of fodder according to agrotechnical requirements. The unloading channel forage is made such a way cut mass enters vehicle for further transportation shortest time possible. accelerator combine provides convenience operation, allowing load into at distance more than 10 m not only vehicles moving next but also be...

Whole-plant corn silage (WPCS) is a major source of forage for dairy cattle in Brazil. Improved kernel processing may be especially advantageous when feeding hybrids with vitreous endosperms. Two experiments were conducted to evaluate the effects theoretical length cut (TLOC) and ensiling time on WPCS particle size two types harvesters. In first trial, plant was harvested by pull-type harvester...

A demonstration was conducted to examine the stored forage yield and stored forage quality of two different hay forage management systems. The forage management systems were a hay harvest only system or a complimentary hayround bale silage harvest system. The hay system harvested bermudagrass forage as hay during the summer when weather conditions allowed, the complimentary system harvested ber...

To govern the commons, states often focus on structures or instruments, such as delegated co-management or tradable quotas. This research argues that this emphasis often presents a trade-off with making investments into socially just action arenas. I revisit the case of the Port Lameron groundfish and lobster fishery in Southwest Nova Scotia, Canada, originally explored by Elinor Ostrom in Gove...

Understanding the factors that underlie the production of non-timber forest products (NTFPs), as well as regularly monitoring production levels, are key to allow sustainability assessments of NTFP extractive economies. Brazil nut (Bertholletia excelsa, Lecythidaceae) seed harvesting from natural forests is one of the cornerstone NTFP economies in Amazonia. In the Peruvian Amazon it is organized...
