Swarm is a European Space Agency (ESA) project that was launched on 22 November 2013, which consists of three Swarm satellites. Swarm precise orbits are essential to the success of the above project. This study investigates how well Swarm zero-differenced (ZD) reduced-dynamic orbit solutions can be determined using space-borne GPS data and optimized pseudo-stochastic pulses under high ionospheric activity. We choose Swarm space-borne GPS data from 1-25 October 2014, and Swarm reduced-dynamic orbits are obtained...

Plants damaged by herbivorous insects often respond by mounting a series of defense responses that can inhibit the insect's fitness. Ostrinia furnacalis (Guenée) (Lepidoptera: Crambidae) is a major insect pest in maize throughout much of Asia, Australia, and the western Pacific islands. We examined the effects of O. furnacalis -induced maize defenses on O. furnacalis fitness, and explained the effects from biochemical changes that occur in maize leaves in response to O. furnacalis feeding. The results of the age-stage, two-sex life table showed that significantly longer larval and pupal life spans, and total preoviposition period (TPOP) occurred...

Spodoptera litura (F.), one of the most devastating pests in many Asian countries, is normally controlled by relying on chemical insecticides. To encourage an integrated pest management approach, we determined the economic injury level (EIL) for S. litura on peanut, Arachis hypogaea L., by larval infestation with late instars at different crop growth stages. The cumulative consumption rate of the fifth- and sixth-instars was used as the relative unit for the "Spodoptera injury equivalent" (SIE). The yield of marketable pods significantly decreased from 6...

Helicoverpa zea (Boddie), corn earworm, is a damaging insect pest of many crops, including soybeans. An economic threshold for soybeans during the pod-filling stages exists to prevent economic damage to seeds. However, the impact of florivory (flower feeding) by H. zea larvae on seed yield is poorly understood and there is no economic threshold for flowering-stage soybeans. Four small plot experiments were conducted in North Carolina during 2011 and 2012 to assess the impact of H. zea feeding during the flowering stages of determinate soybeans on various yield components...

Bradycardia is the most common form of dysrhythmia developing after disruption of the sympathetic pathway by a spinal cord injury (SCI), and it can have fatal consequences, including cardiac arrest. Here, we report a case of cardiac arrest developing after cervical SCI attributable to sympathetic hypoactivity. A 26-year-old male pedestrian was admitted after a traffic accident. Radiologically, fractures were apparent at the C6-7 bilateral articular facets, and cord contusion with hemorrhage was evident at C4-7...

BACKGROUND: Gastric leak (GL) is one of the main early-onset postoperative complications of sleeve gastrectomy (SG). Many institutions perform routine upper gastrointestinal (UGI) contrast studies within 24 hours of surgery, looking for GL or gastric stenosis and to determine the need for urgent re-exploration, but this examination delays oral feeding, can cause side effects and is responsible for systematic and probably unnecessary irradiation of the patient. OBJECTIVE: Determine the efficacy of routine UGI contrast studies to predict postoperative complications after SG in a large population...

Soil salinity is gradually becoming a threat to the global economy by affecting agricultural productivity worldwide. Here, we analyze the salinity tolerance of Pongamia pinnata with an insight into the underlying physiological and molecular responses. Despite a reduction in net photosynthetic rate, P. pinnata efficiently maintained its leaf water potentials even at 500mM NaCl for 15days and displayed no visible stress symptoms. Na(+) localization analysis using CoroNa-Green AM revealed effective Na(+) sequestration in the roots when compared to leaves...
