Six days before arrival, the Mars Express spacecraft released the landing probe Beagle2. This paper extends a reconstruction of the lander’s drift trajectory from atmospheric entry to landing. Uncertainties of the initial drift trajectory and contributions by uncertainties in the atmospheric descent computation are mapped to the landing site. Parameters of key events during the descent are deri...

The survival of the tropical crayfish Cherax quadricarinatus in earthen ponds under ambient winter temperatures was studied in the temperate zone in the central coastal plain of Israel. Four treatment groups in which sex and size were each tested at two levels were simultaneously run in Ž . four replicates over a period of 118 days 28 November 1996–26 March 1997 . Minimum and maximum water temp...

On29March 2005 a 41 year old journalist died of sepsis six days after a minor surgical procedure; she had consulted eight doctors over the intervening Easter bank holiday weekend. Whereas the national press focused on the political question relating to the provision of out of hours medical services in the United Kingdom, the coroner pointed out that “nonrecognition of the seriousness of her con...

Water retting is a traditional retting method that enables the low-cost production of bast fibers. This study investigated the retting of flax straws by distilled water for three different durations at room temperature in laboratory condition. The retting quality was evaluated in terms of the weight loss and degumming rate together with the fiber properties, which included color, linear density...

Dieta.—Male Wistar rats were placed on a semi synthetic diet at weaning, and the food consump tion of each was measured. A week later each rat was paired with one of equal body weight and food consumption. At this time one rat of each pair was designated as the experimental rat which would receive a tumor transplant; the other rat, his pair fed control, consumed the amount of diet eaten by th...

The technical feasibility of geothermal power production will be demonstrated in the geothermal research wells Groß Schönebeck using a borehole doublet. This task includes safeguarding the thermal fluid cycle and the optimisation of energy conversion technology at the surface. In order to complete the Enhanced Geothermal System, three massive hydraulic stimulations were performed injecting a to...

The air quality design value is the mathematically determined pollutant concentration at a particular site that must be reduced to, or maintained at or below the National Ambient Air Quality Standards (NAAQS) in order to assure attainment. The design value may be calculated based on ambient measurements observed at a local monitor in a 3-year period or on model estimates. The design value, howe...
