spruce-dominated forests are commonly exposed to disturbances associated with mass occurrences of bark *** dieback of trees triggers many physical and chemical processes in the ecosystem resulting in rapid changes in the vegetation of the lower forest *** aimed to determine the response of non-tree understory vegetation to the mass dieback of norway spruce(Picea abies)in the first years after the disturbance caused by the European spruce bark beetle(Ips typographus)*** study area was the Białowieża Biosphere Reserve covering the Polish part of the emblematic Białowieża Forest,in total 597km^(2).The main data source comprised 3,900 phytosociological relevés(combined spring and summer campaigns)collected from 1,300 systematically distributed forest sites in 2016–2018–the peak years of the bark beetle *** found that the understory responded immediately to mass spruce dieback,with the most pronounced changes observed in the year of the disturbance and the subsequent ***-tolerant forest species declined in the initial years following the mass spruce dieback,while hemicryptophytes,therophytes,light-demanding species associated with non-forest seminatural communities,as well as water-demanding forest species,*** acetosella,the most common understory species in the Białowieża Forest,showed a distinct fluctuation pattern,with strong short-term expansion right after spruce dieback,followed by a gradual decline over the next 3–4 years to a cover level 5 percentage points lower than before the ***,our study revealed that mass spruce dieback selectively affects individual herb species,and their responses can be directional and non-directional(fluctuation).Furthermore,we demonstrated that the mass dieback of spruce temporarily increases plant species diversity(α-diversity).

It is of great scientific and economic value to recycle waste poly（ethylene terephthalate）(PET) into high-value PET-based metal organic frameworks（MOFs） and further convert it into porous carbon for green energy storage applications. In the present study, a facile and costeffective hydrothermal process was developed to direct recycle waste PET bottles into MIL-53（Al） with a 100% conversation, then the MOFderived porous carbon was assembled into electrodes for high-performance supercapacitors. The results indicated that the as-synthesized carbon exhibited high ssA of 1712 m2g-1and unique accordion-like structure with hierarchical porosity. Benefit to these advantageous characters, the assembled three-electrode supercapacitor displayed high specific capacitances of 391 F g-1at the current density of 0.5 A g-1and good rate capability of 73.6% capacitance retention at 20 A g-1in 6 mol L-1KOH electrolyte. Furthermore, the assembled zinc ion capacitor still revealed outstanding capacitance of 335 F g-1at 0.1 A g-1, excellent cycling stability of 92.2% capacitance retention after 10 000 cycles and ultra-high energy density of 150.3 Wh kg-1at power density of 90 W kg-1in 3 mol L-1ZnsO4electrolyte. It is believed that the current work provides a facile and effective strategy to recycle PET waste into high-valuable MOF, and further expands the applications of MOF-derived carbons for high-performance energy storage devices, so it is conducive to both pollution alleviation and sustainable economic development.

Effect of pH-dependent bath speciation on cobalt electrodeposition from sulfate-gluconate solutions

引用

Transactions of nonferrous Metals society of China 2024年

作者： ewa Rudnik AGH University of Krakow， Faculty of non–Ferrous Metals Al.Mickiewicza 30

pH-dependent multiple equilibria in cobalt sulfate-gluconate bathswerecalculated using stability constants adopted from literature. Changes of the bath speciation were thendiscussed in terms of spectrophotometric experiments and buffering properties of the solutions (pH of 3-10).Cyclic voltammetry indicated changes in electrochemical behavior of cobalt species caused by different ionic composition of the electrolytes. Tafel slopes were calculated and discussed in relation to electroreduction of cobalt species. Chronoamperometric studies showed 3D instantaneous nucleation of cobalt followed by diffusion controlled growth， but it was disturbed at higher pH due to release of cation from gluconate complexes as a limiting step. Diffusion coefficients of cobalt species were found. Changes in the pH werealso reflected by modifications of morphology (sEM)，development of preferred orientation planes(XRD， texture coefficients)and current efficiency， but not thickness of the coatings deposited at constant potential of -1.0V (Ag/AgCl).Anodic stripping analysis showed changes in anodic responses originated from the existence of preferentially oriented planes in cobalt layers.

The break-up tendency of long rod projectiles

引用

Defence Technology（防务技术） 2016年第2期12卷 177-187页

作者： ewa LIDén Andreas HELTE FOI Swedish Defence Research Agency

A model for the tendency of fragmentation of a long rod projectile subjected to armour components in add-on armours such as reactive armour and active protection systems is presented. The model is based on studies of the interaction between a cylindrical streamlined projectile and moving thin plates(backwards moving like the front plate in a reactive armour panel and forwards moving like the rear plate in a reactive armour panel).The assumption behind the model is that the sliding force, with velocity vslidebetween the projectile and the plate, gives rise to a transverse velocity vtransof the projectile segment it passes, which will deflect the projectile segment. This deflection is assumed to be a major reason for the fractures that can emerge along the projectile. The velocity, geometry and material of the projectile and the plate are of importance for the fragmentation of the projectile and the dimensionless parameterδ? = v trans vslideexpresses how these parameters influence the break-up tendency. Experiments and simulations have verified that the identifiedδ?-parameter predicts an increased amount of fragmentation of the projectile with increasing value of this parameter.

AIM:To examine if dietary and socio-economic factors contribute to Helicobacter pylori(H pylori)re-infection. METHODs:The population of patients consisted of subjects in whom H pylori infection had been successfully treated in the *** were divided into two groups:Ⅰ-examined group(111 persons with H pylori re-infection)andⅡ-control group(175 persons who had not been re-infected).The respondents were interviewed retrospectively on their dietary habits and socio-economic factors. REsULTs:A statistically significant lower frequency of fermented dairy products(Ps (P=0.02),and fruit(P=0.008)consumption was noted among patients with H pylori re-infection as compared to those who had not been re-infected. COnCLUsIOn:High dietary intake of probiotic bacteria,mainly Lactobacillus,and antioxidants,mainly vitamin C(contained in fruit and vegetables),might decrease the risk of H pylori re-infection.

文章反思了动物史这一新兴史学领域,并提出了动物史研究的主要论点与未来任务。文章的主要目标是明确苏珊·南斯主编的《历史中的动物》给动物史研究带来的新前景和可能性。这些研究前景和可能性体现在,从动物的视角理解动物中介(将动物看作认识历史的中介和历史中的行动者);在“以人类为中心”的档案中寻找动物的痕迹,并搜集有关动物记述的历史资料。文章还讨论了动物史研究在方法论上面临的困难,尤其是探索动物历史过程中人文社会科学与生命科学合并的可能性。这篇评论思考了动物史研究如何推动学术界反思历史学的学科基础问题。一些学术反思来自于主张彻底进行跨学科研究的学者,其中许多是历史学家。这些学者不仅致力于将历史学与动物心理学、生态学、行为学、进化生物学和动物学等学科结合,而且对历史学科的基本假设提出了质疑:历史学家获得的建构过去知识的地位以及这类知识的认识论地位。在这种语境中,出现了若干问题:我们能否实现“物种间的能力”(埃丽卡·富奇的术语),以创造有关过去的多物种知识?对动物感知变化的研究能否帮助我们提出看待过去的非历史路径?我们能够以多物种的作者身份想象过去的解释吗?
