A relationship is shown between energy requirements and properties of biomass, which is a quite variable material.The relationship between comminution machinery and energy which is necessary for the process is highlighted. The derivation of the model is focused on chipping, but it is generally possible to make it available for both different types of biomass (f. ex. agricultural residues)and different types of comminution machinery (f. ex. hammermills) by using different material properties adjuBiomass energyCongressesBiomass energy662.8Niedzwiecki Lukasz1678728MiAaPQMiAaPQMiAaPQBOOK9910816569303321Guide to Biomass comminution4046559UNINA02874nam 2200601Ia 450 991082870910332120240313221005.01-74224-632-X(CKB)2670000000359972(EBL)1557299(SSID)ssj0001054844(PQKBManifestationID)11588500(PQKBTitleCode)TC0001054844(PQKBWorkID)11134064(PQKB)10143726(MiAaPQ)EBC1192597(MiAaPQ)EBC6216002(MiAaPQ)EBC1557299(Au-PeEL)EBL1192597(CaPaEBR)ebr10700258(OCoLC)845258977(Au-PeEL)EBL1557299(OCoLC)863203920(EXLCZ)99267000000035997220130523d2013 uy 0engurcn|||||||||txtccrA savage history whaling in the Pacific and Southern oceans /John Newton1st ed.Sydney NewSouth Publishing20131 online resource (311 p.)Description based upon print version of record.1-74223-374-0 Includes bibliographical references and index.Front Cover; Title Page; Copyright Page; Contents; 1.

What Now for Whales?Whaleography Bibliography; Acknowledgments; Picture Credits; IndexCelebrated, revered, and studied, whales hold particular allure, but for much of history they have been relentlessly hunted throughout the oceans. A Savage History is a powerful account of a complex and bloody relationship that tells the rich history of whales and whaling, following the stories of whalers from the 18th century to the present day. It explores not only the drama and danger of whaling but the ways in which whales have infused human imagination throughout history. The book also covers the end of industrial whaling and the work still to do to protect these magnificent andWhalingWhalesWhaling.Whales.639.28091644Newton John Sefton1624575MiAaPQMiAaPQMiAaPQBOOK9910828709103321A savage history3959640UNINA
