Sumintary. A spring wheat (Triticumo aestivumin) and(I anl obligate winter wheat (Triticumt compactutm) variety were each grown for 5 weeks in controlled environments at 20 and 250. The threshold for flower induction in the winter wheat was 4 to 5 weeks at 20, whereas the spring wheat had no low temperature requirement for flowering. Changes in the levels of carbohydrate and nitrogen fractions ...

In the Kansas Flint Hills, grassland burning is conducted during a relatively narrow window because management recommendations for the past 40 years have been to burn only in late spring. Widespread prescribed burning within this restricted time frame frequently creates smoke management issues downwind. A potential remedy for the concentrated smoke production in late spring is to expand burning...

Opium arrests life, anesthetises. Well being comes from a kind of death. Without opium I am cold I catch cold I do not feel hungry. I am impatient to impose what I invent When I smoke I am warm, I do not know what colds are, I am hungry. My impatience disappears." "Opium lead s the organism towards death in euphoric mood. The tortures arise from the process of returning to life against one's wi...

the purpose of this research is to analyze heat waves characteristics in the warm period of the year as a climatic hazard in iran. in this study, the daily maximum temperature is taken at 44 synoptic stations during the period 1981-2010. these temperature values were used to extract the intensity, frequency and duration of heat waves using percentile thresholds of 90, 95, and 98. the results sh...

Such a lecture series is prominent on many college campuses, made especially famous by Randy Pausch, a Carnegie Mellon professor whose lecture ironically was his last lecture having just been diagnosed with terminal pancreatic cancer. In Spring 2012, the inaugural UCSF Last Lecture received a warm and welcoming response. This year the student-initiated event will continue to build the tradition...

Air filter samples collected at Sodankylä (6722’N, 2639’E) were analyzed for determining concentrations of Cs, Sr and total beta in surface air at northern Finland during 1963. Activity concentrations of Cs, Sr and total beta varied seasonally being highest in spring and summer, due to enhanced transportation of aerosols containing radioactive particles from stratosphere to troposphere during w...

OBJECTIVES To ascertain whether the weather affects the attendance rate of children with injuries at a paediatric accident and emergency department. METHODS The maximum daily temperature and weather conditions (rain/cloud/sun) were noted over a three month period in spring/summer 2002, together with the number of children attending with new injuries or trauma. RESULTS There was a direct ass...
