Germanium-based wide band gap kesterite semiconductor Cu2ZnGe(S,Se)4 (CZGeSSe) is considered a very promising absorber compound as top cell in tandem devices. Autonomy to tailor the from ~1.47 eV (Cu2ZnGeSe4-CZGeSe) ~2.2 (Cu2ZnGeS4-CZGeS), well non-toxic constituents makes this strong candidate for further scientific exploration. However, record efficiency of Cu2ZnGeSe4 solar cells still signif...

Approximately 7,000 acres of carrots are planted in Michigan each year. The average state yield for fresh market carrots is 8.8 tons (350 50-lb bags) of usable carrots per acre. Yields on good fields with no nematode, water, or other limiting problems may exceed 15 tons (600 50-lb bags) per acre. Minicarrots yield about 11 tons per acre. Processing carrots can yield 35 to 40 tons per acre on go...

Climate variability adversely impacts crop production and imposes a major constraint on farming planning, mostly under rainfed conditions, across the world. Considering the recent advances in climate science, many studies are trying to provide a reliable basis for climate, and subsequently agricultural production, forecasts. The El Niño-Southern Oscillation phenomenon (ENSO) is one of the princ...

BACKGROUND Although extensive research has been performed to control differentiation of neural stem cells - still, the response of those cells to diverse cell culture conditions often appears to be random and difficult to predict. To this end, we strived to obtain stabilized protocol of NHA cells differentiation - allowing for an increase in percentage yield of neuronal cells. RESULTS Uncommi...

drought stress is a major factor limiting crop production. investigation of physiological characteristics related to drought tolerance and crop production may be useful in selecting drought tolerant cultivars as well as in improving crop yield. two drought tolerant (azar2 & back cross roshan) and two drought susceptible (marvdast & shiraz) cultivars were investigated in both greenhouse and fiel...
