Names, Travelers, Transindividuality: Italo Calvino in the 1970s
Sabrina Ovan
Enthymema , 2012, DOI: 10.6092/2037-2426/2704
Abstract: Situating the novel within the cultural, literary and political milieu of the period, this article provides a reading of Italo Calvino s 1979 hypernovel If on a Winter’s Night a Traveler and its relation to the French literary group Oulipo. It analyzes the work s link to questions of authorship and collectivity at the core of 1970s literary, philosophical, and political discourse both in Italy and France. In particular, the analysis concentrates on the function of names in the novel as signifiers of individuality and/or collectivity

Abstract: Melissopalynology (pollen analysis of honey) is an indispensable method to authenticate honey origin and characteristics. It is very effective to determine and control the geographical origin of honeys and it also provides information about other important quality aspects. Melissopalynologists are challenged not only to identify the pollen found in honey but also decide what to do with the presence of pollen grains that are represented in the honey spectra. Pollen analyses of honey can also determine important information about honeybees such as foraging ecology, habitat and vegetation visited, changes in food sources and habitat composition. The advantages of a pollen analysis is that all, or most, nectar sources involved are recognised, and if quantitative data are available, their relationship to each component, or to the dominant source, can be determined. Pollen spectra gave consistent results for the same type of honey from different areas. The large variety of meliferous sources (223) enable in Romania to produce characteristic type of honeys. The interest in the production of unifloral honeys is a higher consumer preference for some honey varieties leading to a commercial interest of the beekeepers. In six sample of commercial unifloral honey, 16 pollen types were identified. These honeys are not especially rich in pollen types and compares with many honeys characteristic of Europe. Plantago pollen grains are irregularly found in these honeys, as elsewhere, although their numbers in any one sample are insignificant. The presence of this pollen type is considered accidental, especially as numbers are always low. Comparison of results from samples extracted by different methods is impossible, for absolute pollen content may vary greatly.

Abstract: 用培养试验模拟研究了在正常水分(22%)、干旱(12%)和高含水量(32%)条件下,普通碳酸氢铵(普碳)、尿素及新型肥料长效碳酸氢铵(长碳)对土壤释放n2o的影响;同时考察了土壤no3-的形成时间和形成量.结果表明,农田中施加的无机氮肥是大气中n2o的重要来源,而长碳与普碳和尿素相比,不但可以明显延后n2o释放高峰期出现时间,而且大多数情况下可以显著减少其释放量(p<0.01).在5个月的监测期内,与普碳和尿素相比其减少n2o释放的比例分别为80.23和88.41%(12%含水量),40.00和27.59%(22%含水量),无减少作用和45.88%(32%含水量).本研究结果提示长碳具有作为农田生态系统n2o减排措施的巨大潜力,同时暗示在农业中用长碳代替目前普遍应用的普碳,可以减少地下水中no3-引起的污染.

Abstract: 应用加有脲酶抑制剂(hq)、硝化抑制剂(dcd)及其组合的标记尿素进行春小麦盆栽试验.结果表明,在生长季节结束时,小麦回收,土壤残留和损失的肥料n各占施入n量的17.65~23.69%、43.72~56.32%和19.99~36.77%.其中,与单施尿素相比,两种抑制剂配合使用处理的肥料n总回收率高16.78%,小麦回收高5.96%.施用氮肥对籽粒贡献最大,占吸收肥料n量43.3~62.0%.
