Fig. 1. The German CHAMP satellite (view from antivelocity direction with GPS occultation antennas) Abstract: The German CHAMP (Challenging Minisatellite Payload) satellite (launched on July 15, 2000) is a geoscience mission aiming for the determination of Earth’s gravity and magnetic field and for GPS-based atmospheric sounding. The atmospheric profiling experiment onboard CHAMP was started in...

We evaluated nutrient uptake efficiency and subsequent leaching fractions for western white pine (Pinus monticola Dougl. ex D. Don) seedlings grown with exponentially increasing or conventional (constant) fertilization in a greenhouse. Conventional fertilization was associated with higher leachate electrical conductivity and greater nutrient losses, which were more pronounced for the more mobil...

AIM The study was undertaken to find out the effect of feeding cottonseed meal (CSM) on performance of hematological and serum biochemical parameters in broiler birds. MATERIALS AND METHODS A 6-week biological trial was carried out with 432-day-old Cobb 400 broiler chicks distributed to nine experimental diets with six replicates, each containing eight chicks. The experimental diets were form...

Last May, Dr. Bibiana Campos-Seijo, Editor-in-Chief of C&EN, tweeted about her new world record in the deadlift for her age/weight category. The video clip of Bibiana lifting a 320-lb barbell was a powerful and literal reminder of how working the body can fuel the brain. Getting out of the lab to hit the gym, pool, basketball court, softball fieldor even the neighborhood sidewalkscan clear th...

A study was conducted to develop a computer model to simulate the spatial variability of field-measured saturated hydraulic conductivity (Ks) using Fourier series analysis. Ks measurements, both in situ and in the laboratory, were made at 150 and 300 mm depths at regular intervals of 4.6 m on two perpendicular transects crossing each other at the centre of a no-till field. Three Fourier series ...

Global Navigation Satellite System Radio Occultation (GNSS-RO) refractivity climatologies for the stratosphere can be obtained from the Abel inversion of monthly average bending-angle profiles. The averaging of large numbers of profiles suppresses random noise and this, in combination with simple exponential extrapolation above an altitude of 80 km, circumvents the need for a “statistical optim...

Purpose: To evaluate whether Millettiae Speciosae Champ. (Leguminosae) can enhance exercise performance as well as ascertain if it a potential functional food material. Methods: The extract of Millettia speciosa Champ. (MSE) was orally administered to mice in 500, 1000, 2000 mg/kg doses to investigate its anti-fatigue effect in both forced swimming and climbing tests. Glycogen, triglyceride (TG...

The simulation of complex light effects such as depth-of-field, motion blur or scattering in participating media requires a tremendous amount of computation. But the resulting pictures are often blurry. We claim that those regions should be computed sparsely to reduce their cost. To do so, we propose a method covariance tracing that estimates the local variations of a signal. This method is bas...

Nearly half of the mammalian genome is occupied by repetitive transposon elements, including longinterspersed nuclear elements (LINEs), short-interspersed nuclear elements, and long terminal repeat retrotransposons. The ability of these transposable elements to propagate and insert randomly throughout the genome plays an important role in genome evolution (1). However, as transposon-mediated in...

Many economically important tree species respond positively to an elevated CO2 environment. However, the variability and stability in growth responses among genotypes grown in a global change environment are generally not documented. The present study investigated the differences, at the seedling stage, among 15 maternal families of jack pine (Pinus banksiana Lamb.) in response to an elevated C...
