这是一座建立在沙漠中的城市，引洪水灌溉出一片绿洲;这是一处失落的文明，曾经诞生了超越雅典、比肩罗马的帝国;这是一朵岩石打造的玫瑰，洪水杀不死，又在黄沙中重现……在约旦哈西姆王国南部的峡谷中，有一座神秘的城市——佩特拉。它被诗人伯根赞颂为“一道举世无双的东方奇观，一座与时间并驾齐驱的玫瑰古城”。

目的哮喘-慢性阻塞性肺疾病肺重叠症(Asthma-chronic obstructive pulmonary disease overlap,ACO)患者的生活质量较低,肺功能较差,病情经常加重。由于暴露于污染环境会加重其症状,增加发病率和病死率,环境管理对其至关重要。旨在通过系统性综述,寻找证据,以指导制订护理干预措施,促进ACO患者对空气质量的自我管理。方法 2023年3月,系统检索CINAHL、Medline、Academic search Complete、scopus、Web of science、Cochrane图书馆、乔安娜布里格斯研究所(Joanna Briggs Institute,JBI)循证实践数据库,以及Google scholar。对纳入研究进行数据提取和综合,并对护理干预措施进行分类。采用JBI研究质量评估工具进行方法学质量评估。结果共纳入5篇来自不同国家的研究。促进ACO患者自我监控空气质量的干预措施包括:警觉性干预措施(医务人员定期巡诊、进行症状评估),监测干预措施(监测室内外诱发因素),教育干预措施(空气质量警报、避免接触过敏原),以及相关政策的影响,如无烟政策和改善空气质量的综合战略。尽管这些研究报告了不同的干预措施,方法质量也存在差异,但这些干预措施显示了预防患者病情恶化、尽量减少急诊就诊和住院治疗的潜力。这些关键点可作为护理干预措施的关键组成部分。结论有必要采取全面措施,让护士参与促进患者自我监控空气质量的多学科团队、提高认识、制订和实施护理干预,从而使ACO患者受益。同时,需要进一步开展研究,以扩大证据基础并完善这些干预措施。

Okra (Abelmoschus esculentus L.) is an herbaceous plant of the Malvaceae family. In Côte d’Ivoire, okra production is estimated to be over 193,000 tons. This low production is largely due to poor soils and hardly covers the needs of the population. To remedy this, growers systematically use mineral fertilizers. However, these fertilizers pollute the environment. To find an alternative to chemical fertilization and increase production, the effect of biofertilizers (spaawet, Retone, super Gro) compared with NPK mineral fertilizer was evaluated on Divo, Teriman, and Djonan F1 cultivars. The trial was set up in a factorial block design with three replications. Plant height, number of functional leaves, and crown diameter were assessed at 60 days after sowing (DAs). The time to 50% flowering, production time, and fruit yield were calculated. The results showed that the biofertilizer Retone induced the highest heights and number of functional leaves, with averages of 61.89 cm and 29.88 leaves, respectively. The diameter at the crown (17.77 mm) was highest with the NPK mineral fertilizer, and the shortest 50% flowering time, with an average of 47.61 days, was also obtained with the biofertilizer Retone. The NPK mineral fertilizer produced the longest production time, with an average of 35.25 days. The highest yields were obtained using Retone (11.07 t/ha) and NPK (9.52 t/ha) fertilizers. The “Divosub>*sub>Retone” interaction produced the highest yield with an average of 12.19 t/ha. The biofertilizer Retone could therefore be used as an alternative fertilizer to chemical fertilization in okra crops, given its effect on the parameters assessed.

Objective: To evaluate the potential of smallanthus sonchifolius(s. sonchifolius) roots in ameliorating hepatic damage of rats fed with a high fructose ***: The effect of s. sonchifolius roots on energy intake, body weight, fat and liver mass was determined in male rats fed with a high-fructose diet. Plasma glucose, triglycerides, total cholesterol, lipoproteins and aspartate aminotransferase and alanine aminotransferase were analyzed. Histological changes of the livers were evaluated by electronic microscopy and apoptosis was examined using the TUNEL method. The levels of malondialdehyde, reducedglutathione and antioxidant enzymes(catalase, superoxide dismutase, glutathione peroxidase, glutathione s-transferase) activities were also ***: s. sonchifolius roots significantly decreased energy intake, body weight, fat and liver mass(P s. sonchifolius roots ameliorated liver steatosis and mitochondrial morphology, avoiding cellular apoptosis and normalizing transaminase activity in the liver of rats fed with high fructose. Enzymatic assays revealed that s. sonchifolius roots had a modulatory effect on the oxidative stress induced by fructose-feeding by reducing lipid peroxidation(P s(P s. sonchifolius roots can ameliorate non-alcoholic fatty liver disease by improving oxidative stress and liver injury.

One of the main factors impacting the reliability of energy systems nowadays is the growing interdependence between electricity and gas networks due to the increase in the installation of gas-fired units. securityconstrained unit commitment(sCUC) models are used to economically schedule generating units without compromising the system reliability. This paper proposes a novel sCUC formulation that includes dynamic gas constraints,such as the line pack, and transmission contingencies in power and gas networks for studying the integrated system reliability. A Benders’ decomposition with linear programming techniques is developed to be able to study large systems. By including dynamic gas constraints into the sCUC, the proposed model accounts for the flexibility and reliability that power systems require from gas systems in the short term. Case studies of different size and complexity are employed to illustrate how the reliability of one system is affected by the reliability of the other. These experiments show how both systems operate in a secure way(by including contingencies) increases operating costs by approximately 9% and also show how these costs can vary by 24% depending on the line pack scheduling.

Copper （II） dicarboxylate, MIL-53, metal-organic framework synthesized hydrothermally has been used for the first time as an adsorbent for methane gas adsorption. Methane adsorption capacity of MIL-53（Cu） was increased to about 8.52 mmol·g-1 at 298 K and 35 bar for methane storage. The adsorbent was characterized by X-ray diffraction （XRD）, Brunauer-Emmet-Teller （BET） method, Fourier transform infrared （FT-IR）, thermo gravimetric analysis （TGA） and scanning electron microscopy （sEM）. The adsorption property of CH4, on MIL-53（Cu） was investigated by volumetric measurement. The enhancement of CH4 adsorption capacity of MIL-53（Cu） is attributed to the increase of micropore volume of MIL-53（Cu）.

Following a seismic event that occurred years ago in Central Italy, the public opinion was growing and growing a concern on the adequacy of educational buildings all across Italy. This activated several political decisions and a consequent technical effort is in progress. Technically speaking one has to manage the classical problem of retrofitting existing buildings. However, the legal environment goes across national codes, targeted guidelines and the professional need of achieving pragmatic solutions based on ethical and social acceptation *** paper introduces the topic in its worldwide exception and focuses then on some operative aspects in the Italian situation. It outlines the consolidated steps along this technical process and emphasizes the weak aspects one meets when going across the designers＇ reports.

A new four-dimensional quadratic smooth autonomous chaotic system is presented in this paper, which can exhibit periodic orbit and chaos under the conditions on the system parameters. Importantly, the system can generate one-, two-, three- and four-scroll chaotic attractors with appropriate choices of parameters. Interestingly, all the attractors are generated only by changing a single parameter. The dynamic analysis approach in the paper involves time series, phase portraits, Poincare maps, a bifurcation diagram, and Lyapunov exponents, to investigate some basic dynamical behaviours of the proposed four-dimensional system.
