工业生产是碳排放的主要来源。减少能源浪费、达成生产节能对实现我国“双碳”目标至关重要。随着数字化技术进步,数字化能源管理系统可通过将不可见的能源可视化,促进企业节能。文章分析了英国、美国、德国、日本和瑞典应用能源管理系统的现状,总结了其特点与应用条件,与我国在此方面的发展进行了对比,并探讨了我国在部署能源管理系统过程中所面临的挑战。文章还提出从“工厂、产线和设备”到“产品”角度分析能耗,构建“基于生产步骤的单位产品能耗标签”的方法论框架。探讨了政府、企业等利益相关者在该方法论中的角色,并提出了政府支持发展数字化能源管理系统的对策,包括推动系统建设、支持合作、确定能耗基准和引导企业对标行业最优实践。

Lack of dietary fiber contributes.to many health is.ues. particularly chronic vas.ular dis.as.s. Mixed linkage β-1.3 - 1.4 beta-glucan (beta-glucan, in this.paper) is.a confirmed beneficial ingredient for the human diet through reduction of choles.erol and the glycemic index. Barley contains.the highes. beta-glucan content of all the grains. and in this.s.udy, a percentage of flour from two high beta glucan lines.was. each, added to an array of wheat-bas.d food products.to meas.re how it impacted total dietary fiber. Res.lts.s.owed that beta-glucan content was.higher in all the products.containing the added high beta-glucan flour, along with increas.d total dietary fiber content. Protein content in the food products.is.als. increas.d with the higher protein in the barley flours.added. Beta-glucan content in the barley-added products.increas.d to 1.2% - 4.0% vers.s.0.2% - 0.5% in the pure wheat products. while the dietary fibers.increas.d to 3.5% - 24.4% vers.s.2.1% - 9.1% in pure wheat product controls. This.res.arch provided experimental evidence that us.ng a high beta-glucan barley ingredient in food can increas. dietary fiber to benefit health.

We report an unus.al cas. of an inherited dis.rder of the des.os.mal protein plakophilin 1, res.lting in ectodermal dys.las.a-s.in fragility s.ndrome. The affected 6-year-old boy had red s.in at birth and s.bs.quently developed s.in fragility, progres.ive plantar keratoderma, nail dys.rophy, and alopecia. s.in biops. revealed widening of intercellular s.aces.in the epidermis.and a reduced number of s.all, poorly formed des.os.mes. Mutation analys.s.of the plakophilin 1 gene PKP1 revealed a homozygous.deletion of C at nucleotide 888 within exon 5. This.mutation differs.from the PKP1 gene pathology reported in 8 previous.y publis.ed individuals.with this.rare genodermatos.s. However, all cas.s.s.ow s.milar clinical features. highlighting the importance of functional plakophilin 1 in maintaining des.os.mal adhes.on in s.in, as.well as.the role of this.protein in as.ects.of ectodermal development.

本文重新解读了中古英语文学作品中手稿变体对句法和意义产生的效果。论文借用“事后性”(弗洛伊德称之为“延迟性”)这一心理分析概念,以《巴斯妇人的开场语》为个案,将变体视为一个双向时间结构。伯纳德·塞尔奎利尼在《对变体的赞美》(1989)中将变体描述为一种产生新句法结构的活动。异文追溯、重构了它嵌入其中的话语的句法。异文不是嵌入固定句法结构的替代词汇选择;它们应被视为动态组合,当它们在话语中出现时,会改变每个话语的结构,往前往后都起作用。因此,意义永远不会准时到达,而是总会延迟。

The s.atial pattern dis.ribution of plant hormones.in res.ons. to aluminum (Al) toxicity in roots.remains.to be s.own. This.s.udy was.performed to as.es. the root hormonal accumulation and gene expres.ion in res.ons. to Al toxicity in five trans.enic miniature dwarf tomatoes.cv. Micro-Tom (MT). MT and MT trans.enics.to acid indole acetic, cytokinin, gibberellin, abs.is.c acid and ethylene were cultivated in nutrient s.lutions.containing different Al concentrations. Root growth elongation was.meas.red and cellular damage was.vis.alized by s.aining evans’s.blue. The GUs.reporter gene s.aining technique was.us.d to vis.alize hormonal changes.in MT apex root tis.ues. Data indicated that the MT is.s.ns.tive to Al that induced s.gnificant growth inhibition and cellular damage. Al concentration of 27 μM was.s.gnificantly toxic, inducing root apex darkening and inhibition of root development. The qualitative evaluation of GUs.reporter gene expres.ion s.owed intens. cros.talk among all hormones.s.udied, unders.oring the complexity of s.gnaling induced by Al in apex roots. Res.lts.point out to a major unders.anding of the hormonal s.gnaling in res.ons. to Al toxicity, which may induce a change of root growth and architecture with growth inhibition and cell cons.raints.modulated by all different hormones.evaluated.

In this.s.udy, geophys.cal and geotechnical s.udies.were carried out in NE Turkey to evaluate the s.ability and s.pport des.gn of cut s.opes.that will be excavated during the cons.ruction of a new border control complex. 13 vertical and 3 inclined boreholes.were drilled, and 2D electrical res.s.ivity tomography s.rveys.were conducted along 8 profiles.to inves.igate the horizontal and vertical continuity of the geological units. s.rength characteris.ics.of all units.were determined by laboratory tes.s. Limit equilibrium(LE) s.ope s.ability analys.s.were conducted on the geological model for s.atic and ps.udo-s.atic conditions.and factor of s.fety values.as.low as.0.227 were determined for pos.-excavation. Back analys.s.was.conducted for the determination of required s.pport forces.on the s.opes.to achieve a factor of s.fety of 1.3. A feas.ble s.pport s.s.em cons.s.ing of bored piles.and rock anchors.was.des.gned bas.d on back analys.s.res.lts.for each cut s.ope. LE analys.s.were repeated after the implementation of the des.gned s.pport s.s.ems.and the lowes. factor of s.fety value increas.d to 1.35. The utility and s.fety of the des.gned s.pport s.s.ems.were inves.igated us.ng finite element s.ope s.ability analys.s.and s.rength reduction factor values.higher than 1.3 were determined which means.s.pport s.s.ems.will function as.intended and no s.pport failure will occur. Las.ly, quick reference charts.were created for alluvium and res.dual s.il materials.to eas.ly determine the s.fe s.ope angle in the future in cas. no s.pport meas.res.will be applied.
