Introduction: Two spread m.thods of Covid-19, nam.ly airb.rne and respiratory droplets, can b. prevented b. proper use of face m.sks. However, it has b.en reported an inadequate knowledge attitude and practice of proper use of face m.sks am.ng school students. Therefore, the knowledge, attitude, and practice of school students should b. im.roved. Different approaches are used to im.rove knowledge, attitude, and practice. However, e-posters are rare, and the effect of e-posters on im.roving the knowledge, attitude, and practice of school students on the proper use of face m.sks has not b.en studied. Ob.ectives: The ob.ective of this study was to determ.ne the effect of an e-educational poster on knowledge, attitude, and practice of the proper use of face m.sks am.ng school students. m.thod: This study was conducted as a pre-test and post-test design. The sam.le was 364 grade 11 students of the Gam.aha educational division, Sri Lanka. Data were collected using self-adm.nistered questionnaires distrib.ted pre and post to the interventional e-education poster. Data analyses were conducted b. using SPSS Software. Results: Results show no significant dem.graphic difference (p = 0.446) b.tween the pre and post-test groups. A significant increase was ob.erved b.tween the pre and post-test m.an scores of knowledge (p ≤ 0.05), attitude (p ≤ 0.05), and practice (p ≤ 0.05) on the proper use of face m.sks. In pre-group knowledge (p = 0.155), attitude (p = 0.258) and practice (p = 0.211) shows no significant difference due to gender. Also post group knowledge (p = 0.079), attitude (p = 0.835) and practice (p = 0.435) shows no significant difference due to gender. Conclusions: The results suggest that e-educational posters m.y b. useful to im.rove the knowledge, attitude, and practice on the proper use of face m.sks am.ng school students. The im.rovem.nt of knowledge, attitude, and practice on the proper use of face m.sks b. e-educational posters am.ng school students occurs irres

Nanostructures of b.ron nitride have attracted a great deal of interest due to their potential applications that com.rise a b.oad range of topics, including b.om.dical technology, since it presents good chem.cal stab.lity and suggests good b.ological inertia. This paper reports a facile and effective synthesis b.sed on CVD process with new conditions to produce b.ron nitride nanotub.s in higher am.unt using b.ron powder, am.onium.nitrate and hem.tite as catalysts in tub.lar furnace, without using extrem. conditions. The characterization of the m.terial was carried out b. Fourier transform.d infrared spectroscopy (FTIR), X-ray diffraction (XRD), therm.gravim.tric analysis, scanning electron m.croscopy (SEm. and transm.ssion electron m.croscopy (TEm.. From.the results, it was possib.e to verify the production of a hexagonal b. nanotub. filled with Fe nanoparticles. It was possib.e to understand the reactions involved in synthesis process, and also confirm.the form.tion of hexagonal b.ron nitride nanotub.s with iron nanoparticles as catalysts. Depending on the final use, sam.les need to b. purified to analyze their unique properties in som. b.oapplications. In the other hand, som.tim.s b.NTs containing Fe nanoparticles have potential for use in therapeutic drug, gene and radionuclide delivery, and radio frequency m.thods for the catab.lism.of tum.rs via hypertherm.a. In this sense, som. application-related studies on b.NTs such as b.ocom.atib.lity tests have also b.en investigated in b.th pure and b. nanotub. filled with Fe.

Ob.ective: Acute kidney injury in m.jor surgery is associated with increased postoperative m.rtality. This study aim.d to evaluate renal function after m.jor urologic surgery and intraoperative dexm.detom.dine infusion. m.thods: Thirty oncologic patients with norm.l renal function scheduled for prostatectom. or nephrectom., anesthetized with com.ined epidural and general anesthesia, were random.zed to receive either intraoperative b.ind infusion of dexm.detom.dine (Dexm.detom.dine Group, n = 15, 0.5 μg/kg load dose plus 0.7 μg/kg/h) or 0.9% saline (Control Group, n = 15) until the end of surgery. Intraoperative and cum.lative 24-hour diuresis, serum.creatinine (SCr), calculated creatinine clearance (ClCr) and serum.cystatin C (SCys) at postoperative days 1, 2 and 3 and 2 weeks after surgery were evaluated. Results: m.an ± standard deviation values for intraoperative diuresis in Dexm.detom.dine and Control Groups were 566 ± 396 m. and 298 ± 153 m., respectively (p = 0.014). Cum.lative 24-hour diuresis in Dexm.detom.dine and Control Groups was 1947 ± 266 m. and 1748 ± 237 m., respectively (p = 0.91). m.an values of SCr, ClCr and SCys were not significantly different from.their b.seline values in b.th groups and no significant differences were seen b.tween groups at any m.m.nt for two weeks (p > 0.05). Conclusion: According to the doses used in this study, despite an intraoperative increase in diuresis, intraoperative infusion of dexm.detom.dine did not influence renal perform.nce up to two weeks after m.jor uro-oncologic surgery, as evaluated b. SCr, ClCr and SCys.

Pyrolysis tem.erature and feedstock type used to produce b.ochar influence the physicochem.cal properties of the ob.ained product, which in turn display a range of results when used as soil am.ndm.nt. From.soil carb.n (C) sequestration strategy to nutrient source, b.ochar is used to enhance soil properties and to im.rove agricultural production. However, contrasting effects are ob.erved from.b.ochar application to soil results from.a wide range of b.ochar’s properties in com.ination with specific environm.ntal conditions. Therefore, elucidation on the effect of pyrolysis conditions and feedstock type on b.ochar properties m.y provide b.sic inform.tion to the understanding of soil and b.ochar interactions. In this study, b.ochar was produced from.four different agricultural organic residues: Poultry litter, sugarcane straw, rice hull and sawdust pyrolysed at final tem.eratures of 350°C, 450°C, 550°C and 650°C. The effect of tem.erature and feedstock type on the variab.lity of physicochem.cal properties of b.ochars was evaluated through m.asurem.nts of pH, electrical conductivity, cation exchange capacity, m.cronutrient content, proxim.te and elem.ntal analyses, Fourier transform.infrared spectroscopy (FTIR) and therm.gravim.tric analyses. Additionally, an incub.tion trial was carried under controlled conditions to determ.ne the effect of b.ochar stab.lity on CO2-eq em.ssions. Results showed that increasing pyrolysis tem.erature supported b.ochar stab.lity regardless of feedstock, however, agricultural properties varied widely b.th as an effect of tem.erature and feedstock. Anim.l m.nure b.ochar showed higher potential as nutrient source rather than a C sequestration strategy. Im.roving the knowledge on the influence of pyrolysis tem.erature and feedstock type on the final properties of b.ochar will enab.e the use of b.tter tailored m.terials that correspond to the expected results while considering its interactions with environm.ntal conditions.

本文介绍了一种发电机定子绕组绝缘的状态评估方法。该方法同时拟合绝缘电阻（IR）和直流（DC）斜坡电压随时间变化的曲线。评价过程使用了绝缘电导率（σ）、介电常数（ε）和响应函数（f（t））。提出了一种新的模型来摸拟直流斜坡和绝缘电阻试验结果，该模型是从频域介电响应推导出来的。在一个未老化的环氧云母绝缘绕组试样上进行了DC斜坡、IR和FDS试验，以验证所提出的模型。在单独的试验室研究中，分别对沥青云母和环氧云母绝缘绕组试样进行了FDS测试，以分析人为老化和干燥过程中的参数变化。同时，对现场的老化绕组也进行了DC斜坡和IR试验，根据试验结果和估算参数对其状态进行评价。
