This article gives an in-depth analysis of the experimental data of the TK-1G sounding rocket installed with the satellite navigation system. It turns out that the data acquisition rate of the rocket sonde is high, making the collection of complete trajectory and meteorological data possible. By comparing the rocket sonde measurements with those obtained by virtue of other methods, we find that...

OBJECTIVE To determine whether the addition of a parental monitoring intervention (Informed Parents and Children Together [ImPACT]) alone or with "boosters" could enhance (either broaden or sustain or both) the effect of a small group, face-to-face adolescent risk reduction intervention Focus on Kids (FOK). METHODS A longitudinal, randomized, community-based cohort study was conducted of 35 l...

The present article shows that all scientific texts included in journals, magazines, and newspapers are vulnerable to the penetration of hedges and boosters.  However, it was found that scientific texts in the three corpora tended to open up the possibilities of alternative voices rather than narrowing them down. The relatively higher frequency of occurrence of hedges in comparison with booster...

crops that better tolerate weed competition or preempt resources from weeds may reduce dependence on herbicides and benefit an integrated weed management program. a field trail was conducted to determine the morphophysiological characteristics affecting tolerance and weed suppressive ability of some winter wheat cultivars in competition with rocket. the experimental treatments consisted of eigh...

Rocket plume temperature distribution plays an important role on the heat transfer analysis of launch carriers. Thus, a non-intrusive IR scanner is used in this paper to analyze the influence of spin motion on plume centerline temperature measurements of spinning solid-propellant rockets. Results show that the average error of temperature measurement is below 3.5% even with a 10% error of estim...

Japanese sounding rocket “S-310-35” was launched from Andøya Rocket Range in Norway on December 13, 2004 during Dynamics and Energetics of the Lower Thermosphere in Aurora (DELTA) campaign, in which the rocket-borne in-situ measurements and ground-based measurements were coordinated to carry out a comprehensive observation of the thermospheric response against the auroral energy input. The inst...

In November of 2003 a rollout test was performed to gain a better understanding of the dynamic environment for the Space Shuttle during transportation from the Vehicle Assembly Building to the launch pad. This was part of a study evaluating the methodology for including the rollout dynamic loads in the Space Shuttle fatigue life predictions. The rollout test was conducted with a partial stack c...

Wild rocket [Diplotaxis tenuifolia (L.) DC.] belongs to the Brassicaceae family and has its origin in the Mediterranean region. The effect of conventional and integrated cultivation practices on the nutritional properties and benefits of wild rocket [Diplotaxis tenuifolia (L.) DC.] were studied. Bioactive molecules content (vitamin C, quercetin, lutein), antioxidant properties and bioactivity o...

This paper presents a laboratory study of body dimensions, seated posture, and seatbelt fit for children weighing from 40 to 100 lb (18 to 45 kg). Sixty-two boys and girls were measured in three vehicle seats with and without each of three belt-positioning boosters. In addition to standard anthropometric measurements, three-dimensional body landmark locations were recorded with a coordinate dig...
