利久酒  [PDF]
张柏青
食品科学 , 1988,
Abstract: ?<正>利久酒是一类配制酒。是以发酵酒、蒸馏酒或酒精为原料、再加糖类、香料和色素配制而成的。这类酒的特点是酒精度较高、香味浓厚、味甜、外观颜色很美观。据传是路易十四世60岁时,因体力衰弱,待医把白兰地加入糖和香料配成药送给路易饮用的。当时把这种饮料叫做兴奋剂、因含酒精故又称为利久酒。利久酒一词来源于拉丁语

Adaptive Routing Algorithm for MANET:TERMITE  [PDF]
Sharvani G S,Cauvery N K,Dr.Rangaswamy.T
International Journal of Next-Generation Networks , 2009,
Abstract: Mobile Ad hoc network consists of a set of mobile nodes. This network does not have anyinfrastructure or central administration, hence it is called infrastructure less network. As the nodes aremobile, it is very difficult to find the path between two end points. This paper presents a solution forfinding path between nodes in mobile ad hoc network. Termite is an innovative algorithm for packetrouting in communication networks. Termite is an adaptive, distributed, mobile-agents-based algorithmwhich was inspired by recent work on the ant colony metaphor. According to this algorithm, a group ofmobile agents (or artificial termites) build paths between pair of nodes; exploring the networkconcurrently and exchanging obtained information to update the routing tables. Some of the parametersused to evaluate its performance are packet delays and throughput. The results of this algorithm showsbetter throughput as compared to existing algorithms. So, Termite algorithm is a promising alternativefor routing of data in commercial networks.
桃蛀果蛾学名的更正  [PDF]
昆虫分类学报 , 1992,
Abstract: 桃蛀果蛾俗称桃小食心虫、苹果食心虫等,简称“桃小”,在国外分布于日本和朝鲜;在我国分布于31°N以北,102°E以东的广大地区,包括吉林、辽宁、河北、北京、天津、山东、江苏、浙江、江西、河南、山西、陕西、宁夏、甘肃、青海、四川等省(市),寄主植物包括苹果、梨、枣、酸枣、山楂、桃、海棠、花红、李、杏、梅等10多种果树。桃蛀果蛾以幼虫取食这些寄主植物的果实,长期以来一直是我国果树生产上的重要害虫,所以国内各地对此虫的生物学、发生规律、防治等方面的研究颇多。目前国内普遍使用的学名是CarposinaniponensisWalsingham,但我国分布的桃蛀果蛾,其学名究竟是不是C.niponensis,却有必要予以澄清,否则将引起混乱。
Preliminary Assessment of the Termite Distribution in Portugal
Nobre,Tania; Nunes,Lina;
Silva Lusitana , 2001,
Abstract: although extensive references can be found on the presence in the last 50 years of subterranean termites, particularly reticulitermes lucifugus (rossi), in portugal, their exact distribution and importance have never been critically evaluated. termites were found to be widespread in the country and are probably the most serious wood destroying insects in buildings. to provide a future working tool that would permit an evaluation of the probability of termite infestation within a given area, an attempt was made to model the probability of the presence of r. lucifugus to a set of environmental variables. logistic regression was the chosen statistical method. four variables were found to explain, in part, the distribution of the data. the overall effect of changes in environmental variables on the probability of termite occurrence is inferred from the model.
Termite Resistant Properties of Sisal Fiberboards  [PDF]
Firda Aulya Syamani,Bambang Subiyanto,Muhamad Yusram Massijaya
Insects , 2011, DOI: 10.3390/insects2040462
Abstract: A study was carried out to test sisal ( Agave sisalana Perrine) fiberboards properties as building materials against Asian subterranean termite, Coptotermes gestroi (Wasmann). Evaluation was in the laboratory according to the JWPA Standard-TW-S.1-1992. To improve mechanical properties of fiberboards made from sisal fibers, the boards were overlaid by rubber veneer, betung bamboo matting or formica. Result showed that the formica-overlaid sisal fiberboards performed better than other overlaid fiberboards against C. gestroi.
Fungiculture or Termite Husbandry? The Ruminant Hypothesis  [PDF]
Tania Nobre,Duur K. Aanen
Insects , 2012, DOI: 10.3390/insects3010307
Abstract: We present a new perspective for the role of Termitomyces fungi in the mutualism with fungus-growing termites. According to the predominant view, this mutualism is as an example of agriculture with termites as farmers of a domesticated fungus crop, which is used for degradation of plant-material and production of fungal biomass. However, a detailed study of the literature indicates that the termites might as well be envisioned as domesticates of the fungus. According to the “ruminant hypothesis” proposed here, termite workers, by consuming asexual fruiting bodies not only harvest asexual spores, but also lignocellulolytic enzymes, which they mix with foraged plant material and enzymes of termite and possibly bacterial origin. This mixture is the building material of the fungus garden and facilitates efficient degradation of plant material. The fungus garden thus functions as an external rumen for termites and primarily the fungi themselves benefit from their own, and gut-derived, lignocellulolytic enzymes, using the termites to efficiently mix these with their growth substrate. Only secondarily the termites benefit, when they consume the degraded, nitrogen-enriched plant-fungus mixture a second time. We propose that the details of substrate use, and the degree of complementarity and redundancy among enzymes in food processing, determine selection of horizontally transmitted fungal symbionts at the start of a colony: by testing spores on a specific, mechanically and enzymatically pre-treated growth substrate, the termite host has the opportunity to select specific fungal symbionts. Potentially, the gut-microbiota thus influence host-fungus specificity, and the selection of specific fungal strains at the start of a new colony. We argue that we need to expand the current bipartite insect-biased view of the mutualism of fungus-growing termites and include the possible role of bacteria and the benefit for the fungi to fully understand the division of labor among partners in substrate degradation.
Termite activity in relation to natural grassland soil attributes
Kaschuk, Glaciela;Santos, Julio Cesar Pires;Almeida, Jaime Antonio;Sinhorati, Deise Cristina;Berton-Junior, Jo?o Francisco;
Scientia Agricola , 2006, DOI: 10.1590/S0103-90162006000600013
Abstract: soil-feeding termites transport soil for mound building, and this process can affect soil characteristics. to verify the influence of soil termite activity on soil characteristics, samples were collected from top, bottom and center of termite mounds, and of the adjacent area, to assess chemical and physical properties and mineralogical composition. four replicates of termite mounds and respective adjacent areas were randomly sampled in lages, cap?o alto, painel, s?o josé do cerrito and coxilha rica (state of santa catarina, southern brazil). results of chemical analyses showed a greater content of k, p, ca, mg and organic c in the inner part of termite mounds, accompanied by lower ph in relation to soil of the adjacent area. there were no differences regarding clay mineral composition between termite mounds and adjacent soil, however the proportion of sand and clay differed between them. it is concluded that termites modify soil characteristics due to great volume of soil transported per ascensum for mound construction (varying from 20.9 m3 ha-1 to 136.6 m3 ha-1, in this study) which promotes a strong pedo-bio-perturbation and affects nutrient cycling and soil physical properties.
