受控核聚变的一种新途径──低能注入式磁盖势阱约束法受控核聚变

提出了磁盖势阱（ＭＬＰＷ）一种静电装置,该装置是在球形静电势阱的外围加上磁盖而构成的,可用于受控核聚变．通过建立磁盖势阱中带电粒子的运动方程并取单粒子谐振子近似以及运用自洽场的统计方法,球形聚变炉内大量带电粒子的集体行为被计算机所研究和模拟．由于使用了电场与磁场的联合约束,与单独的磁约束或惯性约束受控核聚变相比,所需达到的技术指标将有所改善,工程技术上的难度也会有所降低

文章分析了游戏机手柄上盖塑料件的工艺特点,介绍了游戏机手柄上盖注射模结构设计和工作过程。该模具采用浇口开设在顶杆上,在分型时实现自动拉断凝料,同时将曲面分型改为平面分型,降低模具加工的难度,节约成本和提高注塑、脱模的稳定性。生产实践证明,该套模具结构合理,运行可靠。     

新型PET瓶盖杀菌系统的研究与开发

PET瓶超净及无菌灌装技术已成为饮料行业的发展趋势。目前在PET生产线上对瓶盖的杀菌方式主要有紫外线杀菌、倒瓶热力杀菌、化学药剂杀菌等,都存在着杀菌不彻底或者收集处理困难以及成本高等问题。在研究各类杀菌方式、特点的基础上,文章提出了通过过氧化氢喷雾+无菌热空气激发+高强度紫外线结合杀菌的理论,开发一种杀菌彻底,残留少的新型PET瓶盖在线杀菌系统。     

Lean-healthcare approach to reduce costs in a sterilization plant based on surgical tray rationalization

Abstract

Sterilization plants process all reusable materials used in hospitals during different stages of healthcare provision. Most items sterilized come from the surgical theater in the form of individual instruments, linen and surgical trays. Reducing the number of instruments in trays impacts on the performance of the sterilization process. Here, we propose a three-phase method, based on lean healthcare principles, cluster analysis and kaizen groups of experts to rationalize surgical trays, reducing sterilization processing costs. We innovate by proposing a strategy to approach tray rationalization prioritizing surgical specialties that are both complex and frequent, and by using group technology to cluster surgical trays expediting expert analyses carried out by kaizen groups. Our propositions were tested in a high complexity, tertiary care hospital, covering 12 surgical specialties, reducing the number of instruments by average 9.75%, and the time-to-assemble trays by average 9.68%, obtaining annual savings of US$285.756,00 in sterilization processing costs.     

Sex-positive criminology: Possibilities for legal and social change

This article provides an introduction to sex-positive criminology and its goals for change. Sex-positive criminology draws from the “thick desire” organizing principle, which is a rights-based approach to human sexuality, as well as from positive sexuality approaches. It also draws from critical, queer, and feminist criminological traditions and abolitionist sensibilities. We discuss examples that pertain to key tenets of sex-positivity: consent and bodily autonomy, education, medical access, harm reduction, and ways to increase agency. Main topics of discussion include addressing deeply harmful and sex-negative laws and policies that perpetuate state violence, such as coerced or forced sterilization, criminalization of abortion and pregnancy loss, sexual and physical assault of sex workers by police, criminalization through medically inaccurate laws, and legislation such as Allow States and Victims to Fight Online Sex Trafficking Act and the Stop Enabling Sex Traffickers Act that puts marginalized populations at risk. Throughout, we reflect on possibilities for sex-positive laws and policies and the social impacts they would have, such as improving health and well-being.

Webs of empire: locating New Zealand's colonial past

This article reports on the views of non-medical interest groups about sterilization and intellectually disabled people in New Zealand. The rationale for undertaking a study in this sensitive area is presented. Notes about survey distribution method are included and participants’ responses outlined. The study found that a majority of participants agreed that intellectually disabled people should make their own decisions about reproductive capacity. Yet a clear tension between an overall endorsement of individual choice and a majority who also considered that sterilization could be warranted in at least some cases emerged from the data. Reasons for sterilization included: the best interests of intellectually disabled people and carers; concerns about sexual health/well-being; lack of sexual control; and concerns about sexual abuse. The extent of agreement with sterilization as a desirable practice for intellectually disabled boys/men was an unexpected finding. The article concludes with questions posed to promote further discussion.
