{"title":"The Dark Side of Fungal Competition and Resource Capture in Wood: Zone Line Spalting From Science to Application","authors":"Hugh Morris, Kevin T. Smith, PhD, S. Robinson, Maximilian Göttelmann, S. Fink, F. Schwarze","doi":"10.2139/ssrn.3805244","DOIUrl":"https://doi.org/10.2139/ssrn.3805244","url":null,"abstract":"Abstract On wood surfaces and in planar section, zones lines appear as narrow and sharply delineated dark lines within wood visibly altered (“spalted”) by the decay process. In intact wood, zone lines define an irregular volume of decaying wood. They are primarily aggregations of melanised hyphae that enclose wood being decayed by a single genetic individual of a wood decay fungus. In the industry for speciality wood products, zone lines are highly valued, especially for decorative pieces produced from wood turnery. While zone lines are commonly found in naturally infected wood, they can also be induced under controlled conditions. Although with great economic potential for application, there is currently no spalting process to produce zone lines on a commercial scale for niche furniture and construction markets. Successfully spalting wood in a defined timeframe that meets industry expectations requires a knowledge of fungal species, wood colonisation strategies, fungal decay processes along with wood behaviour (i.e. its hygroscopicity), anatomy and wood mechanical properties in relation to fungal decay. This review identifies current limitations of zone-line spalting and looks at a novel approach to inducing wood by combining genetic individuals from the same fungal species, enabling the operator to homogenise the spalting method.","PeriodicalId":356404,"journal":{"name":"AgriSciRN: Agricultural Research & Development (Topic)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127179454","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Conducting Commodity Assessment of Lactose Free and Ordinary (Lactose) Yoghurts on the Example of Ukrainian Producers","authors":"D. Odarchenko, K. Spodar, T. Karbivnycha, Evgenia V.

The results of the consistency assessment indicate that on the surface of sample No. 3 there was a separation of whey and a curd, with an undisturbed clot, which occurred due to the fact that lactose-free yoghurt was produced by the thermostatic method.<br><br>The second stage of the comparative merchandising assessment of selected yoghurt samples was to determine their main physical and chemical parameters in accordance with the requirements of DSTU 4343:2004 «Yoghurts.

{"title":"Networking Rural Expertise","authors":"T. Muilu, Niina Kotavaara","doi":"10.22004/AG.ECON.139078","DOIUrl":"https://doi.org/10.22004/AG.ECON.139078","url":null,"abstract":"The aim of this paper is to analyse emergence of rural expert networks and their function on the basis of an example network. The case study concerns the European Rural Development Network (ERDN). Networking has been regarded as a central model of action during this century for most of fields of society and economy. The European Union emphasizes the role of cooperation between the Member States, organizations and regions. In addition, the EU research framework programmes are based on existing or project-based research networks in most cases. The number of rural networks has risen rapidly during the last years at regional, national as well as international level. In countries dominated by rural areas, especially in those with small population and sparse population structure, the need for networking has been highlighted because of low and scattered number of rural development actors and experts. There is a need to unite the limited resources. Networking is also expected to create new innovations, increase productivity and save public resources. The ERDN originates from Poland in 2002, and since then, the network has expanded such that in 2009 it aggregated rural researchers from around 20 European countries. The empirical material of this paper consists of a web survey directed at participants of ERDN. The survey was carried out in the spring of 2009. The results suggest that the hard-core group of actors is rather small, but they have managed to create and maintain an alive and innovative network of rural researchers. Involvement among the participants seems to have increased during the years, although there are many of those who just “visit” the meetings only once. So far, the network has been relative easy to manage due to the relatively small number of participants but, however, the possible expansion of the network may lead to a need for a new kind of organizational structure. According to opinions of ERDN participants, the greatest future challenges for the network are connected to ideas on even more profound forms of international research cooperation and accomplishment of research applications and proposals.","PeriodicalId":356404,"journal":{"name":"AgriSciRN: Agricultural Research & Development (Topic)","volume":"62 16","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134127147","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
