In this study, the effects of different sowing environment (greenhouse and nursery), pretreatment (cold moist stratification), time (autumn, spring summer) some climate factors (air temperature, relative air humidity, soil temperature moisture) on germination Acer pseudoplatanus L. seeds were studied. Seeds harvested from tree located in Karadeniz Technical University campus. Three trials carri...

The medicinal plant, coastal glehnia (Glehnia littoralis F. Schmidt ex Miq.), belongs to the Apiaceae, which is known exhibit morpho-physiological seed dormancy (MPD). In this study, we aimed determine type of along with conditions for breaking dormancy, and how increase its germination rate mass production. Initially, seeds had undeveloped embryos, gradually developed following cold (5 °C) str...

Shoreward pulses of cold, high salinity, phytoplankton-rich bottom water represent short time scale changes in nearshore hydrography and biological community structure off the leeward coast of Oahu, Hawaii. A three-week mooring deployment in Spring 2009 revealed that ‘cold pulses’ occurred over all phases of the semidiurnal surface tide, but that a statistically greater proportion occurred at l...

Abstract Cold pulses generated by the fission of internal solitary waves over gentle slopes are an important source nutrients and relief from excess heat to benthic ecosystems. This numerical study investigates effect stratification form on produced propagating a smooth, gentle, linear topographic slope in 2D simulations. Three types investigated, namely (i) thin tanh (homogeneous upper lower l...

[1] Four years of sustained glider observations are used to compute the seasonal cycle of hydrographic fields in the central Middle Atlantic Bight (MAB). Results reveal a large phase lag in near bottom temperatures, with peak values occurring in September at the inner shelf, in October at the mid shelf, and in November at the outer shelf. Unlike the northern MAB, the seasonal cycle explains ove...

background: the aim of this study was that the past five years data were collected to analyze the situation of malaria and health facilities in this area for better understanding malaria problem and to find solutions. methods: in this retrospective study data of the last 5 years were obtained from health center of bandar abbas, published papers and reports, weather forecasting organization of t...

Circadian rhythms are widespread in nature and reflect the activity of an endogenous biological clock. In metazoans, the circadian system includes a central circadian clock in the brain as well as distinct clocks in peripheral tissues such as the retina or liver. Similarly, plants have distinct clocks in different cell layers and tissues. Here, we show that two different circadian clocks, disti...
