Radar Absorbing Materials(RAM)are a class of composites that can attenuate incident electromagnetic waves to avoid radar *** carbon allotropes that have the potential to be used as RAM are either carbon nano-tubes(cNTs),graphene,carbon black(cB)and ultimately,sustainable porous carbon(SPc).Here,black wattle bark waste(following tannin extraction)was used as a sustainable source to produce SPc made from biomass *** was characterized and used as aﬁller for a silicone rubber matrix to produce aﬂexible *** elec-tromagnetic performance of this composite was compared with composites made with commercial cB and cNT through reﬂection loss(Rl),where-10 dB is equivalent to 90%of *** composites were evaluated in single-layer,double-layer,and as radar absorbing structures(RAS)with the aim of improving their effective absorption bandwidth(EAB)performances and a reduction in *** cNT composite presented a Rl of-26.85 dB at 10.89 GHz and an EAB of 2.6 GHz with a 1.9 mm thickness,while the double-layer structures using cNT and SPc provided a Rl of-19.74 dB at 10.75 GHz and an EAB of 2.51 ***,the double-layer structures are~42%cheaper than the composite using only cNT since less material is ***,the largest EAB was achieved with a RAS using SPc,reaching~2.8 GHz and a Rl of-49.09 dB at 10.4 ***,SPc made of black wattle bark waste can be a competitive,alternative material for use as RAM and RAS since it is cheaper,sustainable,and suitable for daily life uses such as absorbers for anechoic chambers,sensors,and elec-tromagnetic interference shields for electronics,wallets,vehicles,and others.

AIM： TO assess the safety and efficacy of antioxidant therapy for patients with chronic hepatitis c virus （HcV） infection.METHODS： One hundred chronic HcV infection patients failed in interferon treatment were enrolled and randomly assigned to receive combined intravenous and oral antioxidants or placebo, or oral treatment alone, Primary end points were liver enzymes, HcV-RNA levels and histology.RESUlTS： combined oral and intravenous antioxidant therapy was associated with a significant decline in AlT levels in 52% of patients who received antioxidant therapy vs 20% of patients who received placebo （P = 0.05）. Histology activity index （HAI） score at the end of treatment was reduced in 48% of patients who received antioxidant therapy vs 26% of patients who received placebo （P = 0.21）. HcV-RNA levels decreased by l-log or more in 28% of patients who received antioxidant therapy vs 12% who received placebo （P = NS）. In part 11 of the trial, oral administration of antioxidants was not associated with significant alterations in any of the end points.cONclUSION： Antioxidant therapy has a mild beneficial effect on the inflammatory response of chronic HcV infection patients who are non-responders to interferon. combined antiviral and antioxidant therapy may be beneficial for these patients.

Open Journal of Stomatology 2015年第8期5卷 211-216页

作者： Endang Suprastiwi Itja Risanti nila Kesuma Djauharie Department conservative Dentistry Faculty of Dentistry Universitas Indonesia Depok Indonesia Department Dentistry Fatmawati Hospital Jakarta Indonesia

Background: chlorhexidine could have effect on shear bond strength of composite resin-dentin. Objective: The purpose of this study is to compare two methods of chlorhexidine application of shear bond strength degradation between composite resin and dentin. Methods: Thirty samples of dentin were taken from the crown of premolars and then divided into three groups (n = 10). Group 1 were applied bonding without chlorhexidine, group 2 were applied with liquid chlorhexidine and followed by bonding, group 3 were applied bonding which contains chlorhexidine. Each group was divided into two sub-groups (n = 5): the group with and without 10% NaOcl immersion for one hour. Then, 4 samples in each sub-group were used to measure shear bond strength using Universal Testing Machine, and 1 sample was examined with Scanning Electron Microscope (SEM). Data were analyzed using SPSS 17 by Mann-Whitney and Kruskal Wallis test. Results: The highest mean shear bond strength without 10% NaOcl immersion was in group 1, while the highest mean with 10% NaOcl immersion was in group 3. Significant differences occurred between the groups 1 and 2, groups 2 and 3. conclusion: Method of using bonding contains chlorhexidine can increase and inhibit degradation shear bond strength between composite resin and dentin.

Partnerships for Success： An Evaluation of Head to Toe, a family centered childhood Obesity Intervention that Partners with an Obesity clinic

Journal of food Science and Engineering 2018年第3期8卷 103-111页

作者： Melody Schaeffer claire cioni Jill Schnurbusch Nicole Kozma Sarah Reinhold nila Garba St. louis children's Hospital Child Health Advocacy and Outreach

The prevalence of childhood obesity is a growing epidemic in the United States and as of 2014 its prevalence among children ages two to 19 was 17.0%. Without intervention, obese children are at risk for negative health consequences and for the increased likelihood of staying obese through adulthood. St. louis children＇s Hospital provides HTT （Head to Toe）, an interactive 12-session fimess, nutrition, and social well-being class focuses on adopting healthier lifestyles through daily exercise, and proper nutrition. One program referral method is through a partnership with the hospital＇s HSc （Healthy Start clinic）, a multi-disciplinary obesity clinic. Pretest and posttest assessments are used to measure changes in body metrics, health behaviors, knowledge, readiness to change, and self-concept. Between August 2011 and May 2016, 485 children and at least one parent or guardian with them were enrolled in the program, and up to 235 children completed at least one pretest- or post-assessment. Analysis determined multiple statistically significant improvements in body metrics, health behaviors, knowledge, including questions related to nutrition and food guidelines, readiness to change assessment, and self-concept. Total knowledge increased by 22%; questions related to nutrition increased by 28.2%, social emotional by 18.9% and physical activity by 17.8%. findings suggest that the Head to Toe program is effective in improving nutrition, physical activity, social emotional knowledge and behaviors among participants. childhood obesity is a growing epidemic and creating a relationship with a pediatric obesity clinic can increase the total number of children and teens that are introduced to weight management programs.

文章以广西梧州市某不稳定斜坡为例,详细分析了不稳定斜坡的地质环境条件,斜坡体分布位置、规模、范围及影响因素等,得出不稳定斜坡由人工填土和残积砂质黏性土组成,属于小型浅层推移式土质不稳定斜坡,并对该不稳定斜坡稳定性做定性及定量分析。结果表明:在天然工况下,斜坡体处于稳定状态;在暴雨工况(饱和状态)下,斜坡体处于基本稳定状态。由于坡上荷载较大,如遇持续暴雨不利工况,斜坡将处于不稳定状态,在此基础上提出采用锚杆+格构梁植草加固支护措施。

为使菊花白锈病的抗性鉴定在可控条件下进行,笔者将目测观察与显微镜检方法相结合,制定了菊花白锈病6级抗性鉴定标准,并优化了人工离体接种方法。结果表明,培养瓶内茎段扦插法、培养皿内平铺叶片法均可用于菊花白锈病的离体鉴定;培养瓶内茎段扦插法优于培养皿内平铺叶片法,是最佳的人工离体接种鉴定方法。该优化方法是评价菊花白锈病抗性的既安全又简单的接种方法。
