SRAM Red eTap 11 Speed Rear Mech - Schaltwerke
493,05 € *
ggf. zzgl. Versand

SRAM’s own wireless technology provides a secure connection and the removable battery has a 1000km range. So, if you forget to top up your battery and it runs low miles from home, simply swap it over with the front derailleur's battery to get back on the road with a full cassette range. It also benefits from the same quality construction of the mechanical SRAM Red version, featuring ceramic pulley bearings, a carbon cage, and an anodised alloy body. Technologies: AIREA™ - Utilizing 128-bit encryption, eTap® shift signals are transmitted and received in accordance with SRAM’s proprietary wireless protocol known as AIREA. Each time an eTap groupset is paired, a new encryption code is generated and assigned to the components in this group to ensure complete shifting security. eTAP - All of the underlying tech in the SRAM RED® eTap groupset such as wireless shifting, advanced battery power management and mechatronics technologies are all meant to serve one ultimate purpose, to facilitate the most intuitive and consistent shifting available. This shift logic is called eTap. Right lever makes it harder, left lever makes it easier, both levers shift the front derailleur. Simple, unmistakable, and intuitive. Exact Actuation: When SRAM launched their road technology from scratch they reapplied their MTB proven SRAM 1:1 actuation ratio (shifter cable travel: derailleur movement) for 10 speed rear shifting. EA helps to simplify/stabilise the uneasy act of balancing rear derailleur hanger design, tight cog spacing and exact cable tension. The result: the easiest index shifting system to set up and it stays that way.

Carbon Sequestration in Urban Ecosystems
225,64 € *
ggf. zzgl. Versand

Rapid urbanization started since early 1950s. Among numerous consequences of urbanization are change in landuse and land cover including deforestation, encroachment of prime farmland, and alterations in landscape. These consequences reduce the ecosystem carbon stocks especially in biota and soils, alter the hydrologic cycle by increasing runoff and decreasing soil water storage, change energy budget by altering albedo, and disrupt cycling of carbon and other elements. Such drastic alterations in land use and land cover and biogeochemical cycling of C and other elements affect global climate at local, regional and global scales because of drastic and irreversible changes in the structure, functions and dynamics of ecosystems. The global urban expansion rate is estimated at ~2 million ha (Mha) of additional land to accommodate annual population growth of 70 to 80 millions. Because urban areas consist of build up areas and green areas or free space, judicious management of free space is crucial to moderating the global carbon cycle. Open spaces can be sustainably managed for home lawns, sports grounds, recreational areas, forests, and urban agriculture. Green roofs are also important in influencing the albedo and the carbon and hydrologic cycles. The strategy is to increase the green space areas, enhance their net primary productivity, and increase the overall carbon budget of urban ecosystems. It is also important to link science with policy. Urbanization drastically alters the ecosystems structure and functions, disrupts cycling of C and other elements along with water. It alters the energy balance and influences climate at local, regional and global scales. In 2008, urban population exceeded the rural population. In 2050, 70% of the world population will live in urban centers. The number of megacities (10 million inhabitants) increased from three in 1975 to 19 in 2007, and is projected to be 27 in 2025. Rapid urbanization is altering the ecosystem C budget. Yet, urban ecosystems have a large C sink capacity in soils and biota. Judicious planning and effective management can enhance C pool in urban ecosystems, and off-set some of the anthropogenic emissions. Principal components with regards to C sequestration include home lawns and turfs, urban forests, green roofs, park and recreational/sports facilities and urban agriculture.

The Black Earth
139,09 € *
ggf. zzgl. Versand

Soil is the Earth's living skin. It provides anchorage for roots, holds water long enough for plants to make use of it and the nutrients that sustain life - otherwise the Earth would be as barren as Mars. It is home to myriad micro-organisms and armies of microscopic animals as well as the familiar earthworm that accomplish biochemical transformations from fixing atmospheric nitrogen to recycling wastes, it receives and process all fresh water, provides the foundations for our built environment, and comprises the biggest global carbon store that we know how to manage. This book is about the best soil in the world - the black earth or chernozem: how it is being degraded by farming and how it may be farmed sustainably. Industrialisation of farming has laid bare contradictions between the unforgiving laws of ecology and economics. Soil organic matter is the fuel that powers soil systems and the cement that holds the soil together - and in place - but agriculture is burning it up faster than it is being formed: even the chernozem cannot long survive this treatment. Here is the evidence for this trend and, based on long-term field experiments, ecological principles for sustainable agriculture that can reverse the trend and, at the same time, feed the world. Unlike other volumes in the series, this is not an edited collection of scientific papers. The authors have chosen the classical monograph to be near to the reader from beginning to end - to convey their anxiety about the state of the land and their optimism about the possibility of retrieving the situation by changing the social and political approach to the land so as to provide the necessary incentives for sustainable land use and management.

Seminar paper from the year 2009 in the subject Politics - International Politics - Environmental Policy, grade: 1,5, Grenoble Ecole de Management, course: Business Ethics, language: English, abstract: For many years scientists alert that a climatic change is taking place which is significantly caused by the way human beings are treating their environment. The negative effects of this development had their origin in the end of the 19th respectively in the beginning of the 20th century when the industrialization in many western countries began. With the industrial progress over the last 100 years an increasingly amount of greenhouse gases is released into the atmosphere causing the ecological balance to become incrementally out of order. The impact can be already felt today as temperatures are rising and this is likely to bring about changes for nature including the human beings and many other species. Although the global climatic change is unlikely to be stopped medium-term because carbon dioxide, the greenhouse gas with the largest quantity in the air, is said to have a 100 years+ lifetime span in atmosphere , the effects of the worldwide warming can be mitigated. In the early 1990's this environmental issue was picked up and first steps for global climate policies were made. In 1997, the diplomatic efforts led to the resolution of the so called Kyoto protocol which obligates the member states to reduce its greenhouse gas emissions. This result can still today be seen as a milestone in the international climate policy. Therefore, this agreement will be the subject of examination on the following pages. The author will firstly describe the rationale behind the protocol before underlining its main provisions for developed and less developed countries. Moreover, the effectiveness of the treaty will be critically evaluated and finally emphasize will be also given to the impact it has on my home country, Germany.

The traditional workforce-using the model of the 9-to-5 employee-is a thing of the past. Companies, and their employees, are utilizing flex-time and work-from-home arrangements. Modern telework solutions counter problems of escalating real estate costs, traffic and commuting and employee turnover, and promote carbon footprint reduction and higher employee productivity and satisfaction. Telework has taken center stage as a means to generating productive business. Making Telework Work is a call to action, helping organizations gain competitive advantage in a technology-rich world. Leaders of teleworkers must grasp the big picture while still accounting for the details. To do so means developing capabilities that mark extraordinary leadership, not just run of the mill management.
