the characterization of pore structures and permeability of diesel contaminated clays under different aging

Frontiers of Structural and Civil Engineering   Pages 1264-1280 doi: 10.1007/s11709-023-0921-x

Abstract: to characterize the pore structures and investigate the permeability characteristics of clay after agingThe results of the MIP tests showed that aging leads to reductions in porosity and average diameter,The XRμCT analysis yielded consistent results; it showed that aging renders pores more spherical andMechanistic analysis showed that aging weakens interparticle cohesion; this causes large agglomeratesBoth aging and diesel content can weaken the permeation characteristics of soil.

Role of brown adipose tissue in metabolic syndrome, aging, and cancer cachexia

Meng Dong, Jun Lin, Wonchung Lim, Wanzhu Jin, Hyuek Jong Lee

Frontiers of Medicine 2018, Volume 12, Issue 2,   Pages 130-138 doi: 10.1007/s11684-017-0555-2

Abstract:

Brown adipose tissue (BAT) plays a fundamental role in maintaining body temperature by producing heat. BAT that had been know to exist only in mammals and the human neonate has received great attention for the treatment of obesity and diabetes due to its important function in energy metabolism, ever since it is recently reported that human adults have functional BAT. In addition, beige adipocytes, brown adipocytes in white adipose tissue (WAT), have also been shown to take part in whole body metabolism. Multiple lines of evidence demonstrated that transplantation or activation of BAT or/and beige adipocytes reversed obesity and improved insulin sensitivity. Furthermore, many genes involved in BAT activation and/or the recruitment of beige cells have been found, thereby providing new promising strategies for future clinical application of BAT activation to treat obesity and metabolic diseases. This review focuses on recent advances of BAT function in the metabolic aspect and the relationship between BAT and cancer cachexia, a pathological process accompanied with decreased body weight and increased energy expenditure in cancer patients. The underlying possible mechanisms to reduce BAT mass and its activity in the elderly are also discussed.

Abstract: 在LED灯具加速老化过程中,为获得最小截止时间,对其寿命进行快速预估,本文采用5阶滑动平均误差方法分析数据。选用同批次的16个样本,分别进行80℃和85℃应力条件下的加速老化。首先,采用e指数对光通维持率进行拟合,获得每个灯具的加速寿命,进而采用威布尔分布对加速寿命进行拟合,获得中位寿命。其次,采用平均滑动误差方法,可获取不同截止时间下中位寿命预估误差。结果表明:加速老化过程中,存在最小截止时间,该时间可通过滑动平均误差和截止时间的关系确定;当截止时间小于该值时,寿命预估不合理;寿命预估误差随截止时间增加而逐渐减小。对于该类LED灯具,80℃时最小截止时间为1104小时,寿命预估误差为1.15%;85℃时最小截止时间为936小时,寿命预估误差为1.24%。当寿命估计误差约为0.46%时,80 ℃和85 ℃对应的中位寿命分别为7310小时和4598小时。
