A northern hemisphere thermodynamic climate model is used to compute the effect of the insolation anomalies due to orbital variations in the climates for the next 4000 years. Berger’s mean monthly anomalies of insolation are used in the computations, which are carried out for 1000, 2000, 3000 and 4000 years after present (kyears AP). The numerical simulations show that in the climates of the ne...

` We have, in fact, plans in place for several API 4000 LC/ MS/MS systems,’ said Jim Hulse, senior vice president, bioanalytical, MDS Pharma Services. ` The capabilities of the API 4000 are of critical importance. More and more drugs with highly speci® c pharmacological activities and lower daily dosage recommendations are being developed through pharmaceutical pipelines. The lower the dosage r...

Polyethylene glycol (PEG) 4000 is one of numerous substances used as non-absorbable markers to correct for variable faecal output when assessing daily faecal losses of nutrients. The introduction of enteric coated micro-encapsulated pancreatic enzyme (EMPE) preparations has greatly improved the control of fat malabsorption in cystic fibrosis and chronic pancreatitis patients. Unfortunately, the...

Availability changes with crank angle at the optimum engine operating point of 4000 rpm and WOT for CNG fuelling, CNG and gasoline engine operations at optimal engine conditions with the equivalence ratio Φ = 1.1, distribution of fuel availability of CNG and gasoline fuelled engine at equivalence ratio of Φ = 1.1, entropytemperature diagram for the engine optimal operating point and CNG fuellin...

The present study aimed at characterizing the suppressing effect of contralateral medial olivocochlear (MOC) efferents on human auditory sensitivity and mechanical cochlear responses at sound levels near behavioral thresholds. Absolute thresholds for pure tones of 500 and 4000 Hz with durations between 10-500 ms were measured in the presence and in the absence of a contralateral broadband noise...

BACKGROUND The recording of otoacoustic emissions (OAE) enabled us to prove that the cochlea is able not only to receive sounds but also to produce acoustic energy. Through the use of distortion-product otoacoustic emission measurements, the growth of the response was seen according to the intensity of the sound stimulus presented (growth curve). OBJECTIVE to determine the thresholds for the ...

By 4000 BP, trans-Eurasian agricultural exchanges increased across the Hexi Corridor. However, nature and timing of many early prehistoric remain unclear. We present systematically collected archaeobotanical data from ancient Haizang site (3899–3601 cal a BP) within Adding to previous studies Corridor, we find that production transformed purely millet-based agriculture during Machang Period (43...

PURPOSE To determine trends in utilization and off-label use of polyethylene glycol (PEG) 4000 in children and to determine the prevalence of constipation. METHODS Retrospective cross-sectional analyses were conducted from 1997 to 2007 in a French health care database comprising general practitioners and pediatricians. Patients prescribed PEG 4000 (Forlax(®); Ipsen Pharma, Paris, France) were...

1 Abstract DEC 4000 AXP systems demonstrate the highest performance and functionality for Digital's 4000 series of departmental server systems. DEC 4000 AXP systems are based on Digital's Alpha AXP architecture and the IEEE's Futurebus+ profile B standard. They provide symmetric multiprocessing performance for OpenVMS AXP and DEC OSF/1 AXP operating systems in an office environment. The DEC 400...
