A new monitoring system using GPS is introduced to measure wind‐induced responses of high‐rise buildings. In this paper, wind‐induced responses of a long‐period structure include relative lateral displacements, acceleration records, and torsional displacements at the top of a building. After comparing responses of a test model measured by GPS with responses obtained by the most commonly used laser displacement meters and accelerometers, the wind‐induced responses of a 66‐story high‐rise building subject to the yellow dust storm were measured by the GPS‐based monitoring system. Based on the field measurement, it is concluded that the complete motion history of a high‐rise building can be monitored by GPS. Copyright © 2007 John Wiley & Sons, Ltd. 相似文献

Effects of ambient and elevated CO2 levels (360 and 650 µmol mol?1 respectively), ambient and high (5 °C above ambient) temperatures and their interactions with N application on soybean (Glycine max L.) were studied in 2001. Overall, total isoflavones in whole soybean seeds were highest (1383.0 µg g?1) in the elevated CO2 (AE) treatment without N application and lowest (414.1 µg g?1) in the elevated temperature (EA) treatment with N application. Malonylgenistin (449.2 µg g?1) and malonyldaidzin (435.9 µg g?1) concentrations in the AE treatment without N application were highest among the 12 individual isoflavones, while aglycon and acetyl conjugates showed lower concentrations (below 10 µg g?1) than glucoside and malonyl conjugates in all treatments. Overall, N application had no effect on total isoflavone concentration, while both temperature and CO2 level had a higher effect on increasing isoflavones, including aglycon and acetyl conjugates (P = 0.001). In the biological growth analysis, total dry weight was highest (100.9 g) in the elevated temperature and CO2 (EE) treatment with N application, while leaf area was more affected by CO2 than by temperature and increased with N application. There were larger numbers of pods (99) and seeds (176) per plant in the EE treatment with N application, and generally the AE treatment showed a greater increase in 100‐seed weight (g per 100 seeds) and in pods and seeds per plant than other treatments. Overall, total dry weight was highly affected (P = 0.001) by three main factors, temperature, CO2 and N application, but the interactions temperature × N and temperature × CO2× N did not affect total dry weight. Also, total dry weight tended to increase with increasing numbers of pods (r2 = 0.93***) and seeds (r2 = 0.93***) and larger leaf area (r2 = 0.85***). In addition, numbers of pods and seeds were significantly affected (P = 0.01–0.001) by temperature, CO2 and temperature × CO2. Generally, elevated CO2 and temperature did not affect N, P and K concentrations in the seeds but did decrease the concentrations of Ca and Mg, which were increased in the AE treatment. Among the nutrients, Ca and Mg were highly correlated with temperature and CO2 level. N concentration in the seeds increased with applied N and in particular showed a high increase with elevated temperature and ambient CO2 (EA treatment). The variation in isoflavones was correlated with temperature (r2 = ?0.70**) and CO2 (r2 = 0.67**), while N application was not correlated with isoflavone concentration. Also, Ca (r2 = ?0.85***) and Mg (r2 = ?0.57*) in the seeds were correlated with variation in isoflavones. This indicated that isoflavones were in higher concentrations under conditions of low temperature and increasing CO2, which also resulted in low Ca and Mg concentrations in the seeds. The results of this study suggest that the long‐term adaptation of the soybean to growth at elevated CO2 level and high temperature might potentially increase its isoflavone content, growth and yield.

BACKGROUND: The increase in drug‐resistant bacteria and the ban on antibiotic growth promoters worldwide make the search for novel means of preventing bacterial infection and promoting growth performance imperative. In this sense, antimicrobial peptides are thought to be ideal candidates owing to their antimicrobial properties, broad spectrum of activity and low propensity for development of bacterial resistance. The aim of the present study was to investigate the effect of dietary supplementation with antimicrobial peptide‐P5 (AMP‐P5) on weanling pig nutrition. RESULTS: A total of 240 weanling pigs were allotted to four treatments on the basis of initial body weight. There were four replicates in each treatment, with 15 pigs per replicate. Dietary treatments were negative control (NC, basal diet without antimicrobial), positive control (PC, basal diet + 1.5 g kg?1 apramycin), basal diet with 40 mg kg?1 AMP‐P5 (P5‐40) and basal diet with 60 mg kg?1 AMP‐P5 (P5‐60). Pigs fed the PC or P5‐60 diet showed improved (P < 0.05) overall growth performance, apparent total tract digestibility of dry matter, crude protein and gross energy and reduced (P < 0.05) faecal and intestinal coliforms compared with pigs fed the NC diet. CONCLUSION: The results obtained in this study indicate that dietary supplementation with 60 mg kg?1 AMP‐P5 has the potential to improve the growth performance and apparent total tract digestibility of nutrients and reduce coliforms in weanling pigs. © 2012 Society of Chemical Industry 相似文献

We deposited (K0.5Na0.5)(Mn0.005Nb0.995)O3 (KNMN) thin films on Pt(111)/TiO2/SiO2/Si(100) substrates with a top electrode of indium tin oxide and investigated photocurrent properties in the wavelength range of 300?400 nm. Before the photocurrent measurement, the KNMN film was poled by applying a DC voltage. The photocurrents strongly depend on the wavelength of the incident photon energy. The photocurrents of the first measurement with poling in the up (?5 V) and down (+5 V) states were 21 and 3.2 nA/cm2, respectively, at 344 nm. The difference in the photocurrents in both poling directions was explained by a space charge due to an asymmetric Schottky barrier height, which was caused by an internal electric field and polarization in the KNMN thin film. 相似文献

x
)O3 system have been investigated for compositions fromx = 0 tox = 0.20. Thea axis lattice constant increases at room temperature as substitution of tin for titanium increases, while thec axis lattice constant decreases. The dielectric constant increases and the Curie temperature is shifted to lower temperature as the amount of tin increases. 相似文献

Diagnostic investigations commenced on the 28th of June 1994 in Hungary's and Central Europe's first PET Centre at the University Medical School of Debrecen. The Centre is equipped with a GE 4096 Plus whole body PET scanner. A metabolic tracer, 18F-deoxy-D-glucose (FDG), was used in the investigations. During the first 15 months 249 PET investigations were made in the Centre of which 242 were diagnostic and 7 normal subjects served as control for the patient studies with brain scans. The number of oncological indications (intra- and extracranial tumours, Hodgkin's lymphomas) was n = 105 (43.4% of the 242 diagnostic examinations), neurological investigations (without intracranial tumours) formed the dominant group (n = 117; 48.3%), whereas the number of cardiological indications was 20 (8.3%). The oncological studies included those of intracranial tumours (n = 76; 31.4%); thyroid tumours (n = 9; 3.7%); Hodgkin's lymphomas (n = 7; 2.9%) and other extracranial tumours (n = 13; 5.4%). The distribution of different neurological and psychiatric investigations was as follows: localization of focal epileptogen zone (n = 60; 24.8%); differential diagnosis of dementias (n = 30; 12.4%); exploration of cerebrovascular diseases (n = 10; 4.1%); and other neurological diseases (n = 17; 7.0%). The main objective of the cardiological PET investigations was the exploration of viable myocardium. The present paper overviews both the procedures (including administrative issues, as well) and the results of the first 249 FDG-PET investigations. 相似文献

The authors report a case of bilateral primary malignant lymphoma of the breast presenting during pregnancy in a 24-year-old woman. After delivery of a healthy premature infant by Caesarean section, polychemotherapy was employed. The efficacy of the treatment could not be evaluated since the patient died within a very short period of time. Autopsy and histological examination revealed infiltration of Burkitt-type lymphoma in the breast, ovary, brain, liver, kidney, adrenal gland, pancreas, stomach, bone marrow and myocardium. 相似文献

The effects of oleanolic acid (OA) and ursolic acid (UA) on the fluidity and stability of dipalmitoyl phosphatidylcholine
(DPPC) liposomal membrane were monitored by measuring the fluorescence polarization of 1,6-diphenyl-1,3,5-hexatriene labeled
in the liposomal membrane and the leakage of calcein from the probe-encapsulated liposomes. The experiments with the liposomes
made of DPPC and OA or UA showed that OA and UA exhibited a moderate fluidity-modulating effect for the liquid-crystalline
liposomal membrane, and a strong condensing effect for both crystalline and liquid-crystalline liposomal membranes. Their
effects were comparable to those of cholesterol. These results suggest that their fluidity-modulating and condensing effects
might have some implications in their biological functions. 相似文献

An efficient synthesis is used for the first time to prepare CaCu3Ti4?xWxO12 (x = 0.01, 0.03, and 0.05) electroceramics for energy storage capacitors. CaCu3Ti4?xWxO12 ceramics are synthesized via flame synthesis of metal nitrates precursors in nonaqueous solution using cheap, stable, and insoluble solid TiO2 powder. The pathway yielded a CaCu3Ti4O12 (CCTO) phase with the traces of CuO and CaTiO3 sintered at 1050°C for 30 h. The SEM micrograph shows the grains with smooth surfaces associated with cubical appearance and the size range of 1.5–7, 2.0–7.5, and 2.0–8.0 μm for CCTWO01, CCTWO03, and CCTWO05, respectively. The EDX and XPS analyses show the presence of Ca, Cu, Ti, W, and O elements confirming the purity of these ceramics. The complex impedance and modulus (M) spectroscopy show that the dielectric constant (εr) values of the W‐doped CCTO were dominantly affected by the electrical properties of the grain boundary, which is also evident from the SEM micrographs. The grain‐boundary resistance decreased with increasing tungsten content. The activation energies for the grain boundaries were calculated from the impedance and modulus data using the slope of the ln τ versus 1/T and were found to be in the range 0.62–0.67 eV. 相似文献
