Ecuador potato crop is family based production system. Potato production has two roles in their economy, the first is providing food for their families and the second is a source of income for the household. However small scale farmers have limited access to local markets and most of the sales are through intermediates’ who purchase directly in the field at the lowest price possible. Potato production challenges for the small-scale farmers are among others availability of quality potato seed, direct sales, purchase of agrochemical inputs to maintain their crops and lack of education. In 2021, only 4% of potato farmers used certified seed. Potato yield is still low around 16.1 t·ha-1, in the last 10 years the total potato cultivated area was reduced by at least 50%. The farmers produce “Bokashi” and other organic fertilizer and these are effective to improve soil fertility and plant health. Homemade bio-pesticides reduce agrochemical pesticides. The Decision Support System (DSS) is a handheld device to control late blight, minimizes fungicide applications and improve fungicide rotation. In 2018 Candidatus Liberibacter solanacearum (Lso), the causal agent of zebra chip, and its vector, the potato psyllid Bactericera cockerelli, together created havoc for farmers and researchers. Promotion of early potato varieties INIAP—Libertad is an alternative to lower the impact of this newest pest.

戴维·米勒早期关注社会正义,随着全球化的进程推进,后期则关注全球正义。米勒全球正义思想的前提就是批判全球平等主义。全球平等主义理念来源于世界主义,它主张国家边界内的社会正义可以扩充至全球层面以实现全球正义。米勒认为全球正义与社会正义在背景条件、适用范围和责任主体等都不尽相同,全球正义不是社会正义的扩展版,国内社会正义原则不适用于全球领域。米勒在国内领域坚持多元主义的社会正义原则,在全球领域坚持保障基本人权的底线原则和民族责任原则,但保障基本人权的底线原则支持的是“弱式的世界主义”,实际上认肯了某种形式的全球平等主义,这凸显了米勒共同体主义正义思想的困境。米勒的社会正义与全球正义观点的矛盾反映了道德情境主义与普遍主义正义之间存在内在张力,立足于现实乌托邦的共同体主义全球正义与立足于道德乌托邦的世界主义全球正义思想存在冲突与对抗,充满了内在思辨张力,而“人类命运共同体”新理念是走出这个困局的现实途径。

近年来,印刷电子技术作为一种可实现低成本、大面积电子系统的技术,已获得了可观的收益。印刷允许进行充分有效的处理,从而降低了过程的复杂性,减少了材料的使用种类。加上使用如塑料、金属箔等低成本基板,预计印刷电子技术能实现更多领域电子系统的简单开发,包括显示器,传感器和RFID标签等。回顾印刷电子技术开发及应用工作,通过合成无机纳米粒子和有机材料的结合,可以制成一系列的印刷电子"油墨",并用于印刷无源元件、多层互联结构、二极管、晶体管、存储器、电池、不同类型的气体和生物传感器。通过拓展印刷能力,进一步降低将多种功能材料集成在相同基板上的成本。因此,开发出具有该优势的印刷系统是有可能的。

目的比较白内障超声乳化摘除和小切口无缝线囊外摘除的疗效。对108例明显白内障患者进行前瞻性,随机比较。方法设备:显微眼外科扶贫诊所;病人:108例白内障病人随机接受白内障超声乳化摘除和小切口无缝线囊外摘除;并植入白内障手术植入人工晶体;主要检测:手术时间、手术并发症、术后视力和最好矫正视力、散光、中央角膜水肿情况。结果两种手术都有很好的手术效果而且并发症少。术后第一天,两组病例的未矫正视力无显著性差异(=0.185),而小切口组的角膜水肿发生率要低于超乳组(=0.0039)。六个月后,小切口组有89%病人未矫正视力达到20/60以上,98%病人的最好矫正视力达到20/60以上,而超乳组,这两个比例未85%和98%,两者无统计学上差异(=0.30)。在手术时间上,小切口的手术时间明显少于超乳组,二者有统计学上差异(<0.0001)。结论小切口和超乳都有很好的手术效果和低并发症。两者相比。小切口手术更快、费用低、对技术要求低。因此,小切口白内障摘除是治疗发展中国家成熟白内障的有效治疗方法。
