Performance of a base isolator with shape memory alloy bars

引用

Earthquake Engineering and Engineering Vibration 2007年第4期6卷 401-408页

作者： Fabio Casciati lucia Faravelli Karim Hamdaoui Dept. of Structural Mechanics University of Pavia Pavia Italy

A new and innovative base isolation device is introduced in this paper based on extensive research carried out by the authors and their co-workers. A prototype of the device was built and experimentally tested on the shaking table. The new base isolation device consists of two disks, one vertical cylinder with an upper enlargement sustained by three horizontal cantilevers, and at least three inclined shape memory alloy （SMA） bars. The role of the SMA bars is to limit the relative motion between the base and the superstructure, to dissipate energy by their super-elastic constitutive law and to guarantee the re-centring of the device. To verify the expected performance, a prototype was built and tested under sinusoidal waves of displacement of increasing frequency with different amplitudes. It is shown that the main feature of the proposed base isolation device is that for cyclic loading, the super-elastic behavior of the alloy results in wide load-displacement loops, where a large amount of energy is dissipated.

Objective: To explore the effects of aqueous extract from Phthirusa pyrifolia leaves(67 mg/kg body weight for 12 days) on the reproductive function of male Wistar rats through oral ***: Animals(n = 30), aged 13 weeks and weighing(378.5 ± 5.0) g, were housed in a vivarium under controlled environmental conditions [photoperiod of 12 h light/dark,temperature of(23 ± 1)C] and were fed standard rations ad libitum. The experiment ran for 12 days, wherein animals were divided into three groups: negative control(n = 6)received water, positive control(n = 12) with finasteride at a concentration of 1.0 mg/kg;and a test group(n = 12) submitted to aqueous extract. At the end of the experiment, the animals were sacrificed and submitted to ***: The morphological results of the testes showed that the aqueous extract induced significant changes in the diameter and cross-sectional area of the seminiferous tubules as well as the thickness of the seminiferous epithelium. Furthermore, the extract was able to abruptly decrease testosterone concentrations by about 81.88% in the treated group when compared with the negative control,(47.0 ± 4.8) ng/d L and(255.0 ± 2.0) ng/d L,respectively, and 76.8%,(211.0 ± 8.7) ng/d L, when compared with finasteride. However,the extract causes neither liver damage nor impairment of renal ***: These results suggest that the high amounts of flavonoids shown to be in the extract may be responsible for its hepato-protective effects and suggest a possible decrease in the libido and reproduction of rats.

Transport and Metabolism of the Endogenous Auxin Precursor Indole-3-Butyric Acid

引用

Molecular Plant 2011年第3期4卷 477-486页

作者： lucia C. Strader Bonnie Bartel Department of Biochemistry and Cell Biology Rice University Houston TX 77005 USA

Plant growth and morphogenesis depend on the levels and distribution of the plant hormone auxin. Plants tightly regulate cellular levels of the active auxin indole-3-acetic acid （IAA） through synthesis, inactivation, and transport. Although the transporters that move IAA into and out of cells are well characterized and play important roles in devel- opment, little is known about the transport of IAA precursors. In this review, we discuss the accumulating evidence sug- gesting that the IAA precursor indole-3-butyric acid （IBA） is transported independently of the characterized IAA transport machinery along with the recent identification of specific IBA efflux carriers and enzymes suggested to metabolize IBA. These studies have revealed important roles for IBA in maintaining IAA levels and distribution within the plant to support normal development.

Hyperkalemia in Patients on Peritoneal Dialysis: Clinical Use Experience with New Potassium-Binders

引用

Open Journal of Nephrology 2024年第3期14卷 324-333页

作者： Gennaro Argentino Mario Iorio Alessandra Antonia Mele Andrea Camocardi Enrica Emanuela Cascone Maria Elena Liberti Adelia Sagliocca Andrea Pota Luigi Russo Maria Luisa Sirico Germano Terzini Michele Cavasso Chiara Mennillo Francesca Nettuno Raffaele Genualdo Giuseppe Surfaro lucia Di Micco UOC Nefrologia e Dialisi Ospedale del Mare Naples Italy UOC Chirurgia Generale Ospedale del Mare Naples Italy

Background: Patients with end-stage kidney disease (ESKD) on maintenance dialysis have a high risk of developing hyperkalemia. In addition to traditional approaches, a new option for the management of patients on dialysis includes the use of a potassium binder, sodium zirconium cyclosilicate (SZC). We evaluated the effect and safety of SZC in patients with chronic PD. Objective: To present a case series that illustrates the real-world use of new potassium-binders in hyperkalemic patients on peritoneal dialysis. Methods: This case series collected 9 patients on PD with baseline potassium values > 5.5 mmol/l and who were treated with SZC 5 g once a day. Data were collected at baseline and at 1, 2, and 3 months after initiation of treatment. Results: The median age of patients was 64.5 years and the median duration of observation was 90 ± 5 days. It was observed that median serum potassium decreased (5.8 mmol/l at baseline with a range of 5.8 mmol/L - 6.8 mmol/L versus 4.5 in the third month with a range of 3.6 mmol/L - 5.3 mmol/L) after SZC treatment. Adverse events were observed in 2 (22.2%). The unique adverse event was constipation and presented in 2 patients (22.2%). Constipation was mild and transient during the observation period. No adverse events of special interest were reported. Conclusion: Normokalemia was established and maintained in this series of patients treated with SZC. No episodes of hyper- or hypo-kalemia were observed. SCZ had a good safety profile and was well tolerated over 3 months.
