LEED Practices, Certification, and Accreditation Handbook

Followed within the usa and several other international locations, LEED? certification is the famous usual for measuring construction sustainability. reaching LEED? own certification or venture certification is how one can reveal that the venture is really ''green. '' Written via an architect with over 30 years of overseas event, this e-book presents architects, designers, construction vendors, and building engineers with a simple to appreciate advisor to the nuts and bolts of LEED?

Ecological Effects of Water-level Fluctuations in Lakes (Developments in Hydrobiology)

Such a lot aquatic ecosystems have variable water degrees. those water-level fluctuations (WLF) have a number of results at the organisms above and less than the waterline. usual WLF styles in lakes warrantly either productiveness and biodiversity, whereas premature floods and droughts could have unwanted effects. Human affects on WLF have resulted in a stabilization of the water degrees of many lakes by means of hydraulic rules, premature drawdown because of water use, or floods because of water unencumber from hydropower crops within the catchments.

Wassertechnologie: Fällung · Flockung · Separation

Fallung, Flockung und die dazugehorige Abtrennung sind "Arbeitspferde' der Wasseraufbereitung, ebenso wie die mechanisch-biologische Behandlung das wichtigste Grundverfahren der Abwasserreinigung ist. Mit zunehmender In tensivierung der Wassernutzung und der sich ergebenden Verkiirzung des natiirlichen Wasserkreislaufes verlieren sich die Unterschiede zwischen Wasser aufbereitung und Wasserreinigung mehr und mehr.

Average-weighted ecosystems. A2 B3 137 Cs specific activity in different components of forest In general, the total 137Cs activity is non-uniformly distributed. In each forest ecosystem, three key components play a major role in the migration of 137Cs (Fig. 11). Common to all ecosystems were the soil (including the forest litter and the mineral layers) and the tree canopy, containing about 88% of 137Cs activity in the Cladonio-Pinetum, 90% in the DicranoPinetum and 93% in the Molinio-Pinetum. Also important were the lichen layer (12% in the Cladonio-Pinetum), and the moss layer (9% in the Dicrano-Pinetum and 7% in the Molinio-Pinetum).

Because the contaminated areas are often very large, off-site soil treatment technologies are prohibitively expensive (Gerth et al. 2003). Facilities for the treatment of explosive contaminated ground- and surface water have to be operated over decades. Since there is a need for cost-effective new technologies for the remediation of soil and water, biological technologies for the treatment of TNT in both media have been developed and applied. We present an overview of the in situ remediation of a former trickling pond by autochthonous microorganisms, and the treatment of explosive-polluted surface water from a firing range.

ORLOV ET AL. 40 5. , 2000). , 1996). The model for the migration of 137Cs was based on the compartmental method, as proposed by Georgievsky (1994), and the conceptual scheme used to create the model has been described in detail by Yanchuk et al. (2002). The structure of the model can be represented as a system of linear ordinary differential equations, where each equation describes 137Cs migration into and out of the compartment: dxk dt ¦ ai _ k ˜ l i _ k ˜ xi  xk ˜ ( ¦ ak _ i ˜ l k _ i  O  qk ) , i 1,n, i zk i 1,n, i zk In this equations, lk_i are the coefficients of the compartments’ ties; xi is the 137Cs activity in a given compartment; O is the half-life of 137ɋs; q is the coefficient of 137Cs fixation by the compartment; ai_j are the weight coefficients of the model.
