Photovoltaic mismatch losses caused by moving clouds
Mismatch losses is a major issue in the photovoltaic (PV) system and are mainly caused by partial shading; largest mismatch losses are caused by sharp shadows. These shadows are a typical problem for rooftop and residential installations. In large-scale PV plants, partial shading is mostly caused by moving clouds which produce gentle irradiance transitions causing typically only minor irradianc...

متن کاملCrop losses by insects and the problem of control.
Food losses in field and store 5 cause outstanding losses in many crops. Because there are few trained nematologists, many other important nematode problems on key food crops such as rice and paddy remain uninvestigated. Because nematodes are soil organisms, control is especially difficult. Few satisfactory nematicides are known and these are too expensive for most agricultural crops in Europe....
متن کاملAutomatic Quantification of Destructive Changes Caused by Rheumatoid Arthritis
Rheumatoid arthritis is an incurable disease affecting predominantly peripheral joints of the appendicular skeleton. It can lead to severe disabling mutilations and even to the complete destruction of the joints. The accurate and reproducible quantification of the progression of the disease and of the destructive changes caused to the joints is a decisive factor during therapy and during clinic...
متن کاملInsects Overshoot the Expected Upslope Shift Caused by Climate Warming
Along elevational gradients, climate warming may lead to an upslope shift of the lower and upper range margin of organisms. A recent meta-analysis concluded that these shifts are species specific and considerably differ among taxonomic lineages. We used the opportunity to compare upper range margins of five lineages (plants, beetles, flies, hymenoptera, and birds) between 1902-1904 and 2006-200...
