Maintaining electron flow through the photosynthetic apparatus, even in the absence of a sufficient amount of NADP as an electron acceptor, is essential for chloroplast protection from photooxidative stress. At least two different pathways are thought to participate in this process, i.e. cyclic electron flow and the water-water cycle. Although the function of the water-water cycle was inferred ...

Microscopic oil displacement of water flooding and sweep efficiency of continuous gas injection could be improved by water alternating gas (WAG) injection. The WAG injection process aims to squeeze more oil out of the reservoirs; in this method, water and gas are alternatively injected into the reservoir. Also, availability of hydrocarbon or CO2 gases in the field makes it attractive for gas-ba...

Atmospheric reactions and slow geological processes controlled Earth's earliest nitrogen cycle, and by ~2.7 billion years ago, a linked suite of microbial processes evolved to form the modern nitrogen cycle with robust natural feedbacks and controls. Over the past century, however, the development of new agricultural practices to satisfy a growing global demand for food has drastically disrupte...

the importance of environmental protection in modern communities is vital, the action and implementation of any program requires the sufficient knowledge and understanding of environment. one of the methods to preserve natural resources and achieving sustainable development, especially sustainable agriculture, is the environmentally evaluation of agriculture production processes. life cycle ass...

The TROpospheric WAter RAdiometer (TROWARA) is a ground-based microwave radiometer with an additional infrared channel observing atmospheric water parameters in Bern, Switzerland. TROWARA measures with nearly all-weather capability during dayand nighttime with a high temporal resolution (about 10 s). Using the almost complete data set from 2004 to 2016, we derive and discuss the diurnal cycles ...

The continuous expansion of urban areas is associated with increased water demand, both for domestic and non-domestic uses. To cover this additional demand, centralised infrastructure, such as water supply and distribution networks tend to become more and more complicated and are eventually over-extended with adverse effects on their reliability. To address this, there exist two main strategies...

Water authorities around the world are faced with the problem of ageing distribution networks and often only limited historical data on which to base a sound long term, cost efficient replacement policy. The LICAN approach to whole of life costing is introduced and a hypothetical case study is used to demonstrate the importance of such an approach. A selection of pipe networks utilizing differe...
