Mala in srednje velika industrijska mesta v Alpah so običajno na obrobnih območjih in so pogosto razvrednotena. Navedeno je večinoma posledica tega, da so se industrijske krajine v zadnjih dveh letih ...spremenile v razvrednotena območja, katerih prenovo ovira več dejavnikov. Med njimi so upad števila prebivalcev, slabšanje poslovnih priložnosti, draga okoljska sanacija in zahtevno upravljanje preobrazbe. Avtorji v članku proučujejo, katere možnosti za prenovo imajo alpska mesta z razvrednotenimi industrijskimi območji, katero podporo zagotavlja Evropska unija in koliko razvojnega potenciala se dejansko na ta način v celoti uresniči. Obravnavana so štiri obrobna območja v štirih alpskih državah: v Avstriji, Franciji, Italiji in Sloveniji. Izsledki kažejo, da veljavne politike EU nezadostno urejajo razvrednotena območja. Finančne spodbude so razpršene med več viri, zaradi česar jih je težko črpati, poleg tega na proučevanih območjih ni zadostnega znanja in zmogljivosti za pridobitev sredstev, ki jih potrebujejo za to, da svoje zamisli pretvorijo v uspešne zgodbe o prenovi.
Mesta river is a cross-border river with Greece, whose catchment area includes parts of Rila, Pirin and the Rhodope Mountains. The karst is developed in pre-Paleozoic marble that forms isolated ...outcrops with different basins. The largest of them forms two alpine karst basins located in Northern Pirin and Slavyanka Mountains. In the Rhodopes region, the marble outcrops are fragmented and embedded in non-karstic rocks. They are drained from springs with relatively low flow rates. The largest karst springs drain different hydrodynamic zones of the karst massif of Northern Pirin. From the karst basin of Slavyanka Mountain, only the large subthermal spring near the village of Musomishta falls into the catchment area of the Mesta river. The data on the chemical composition of some of the karst springs are summarized, paying attention to the largest of them. An analysis of the changes in the chemical composition and comparison is made. The changes of the hydrochemical parameters of the springs draining different vertical zones in Northern Pirin are compared. The obtained results prove that the main role in the formation of the chemical composition of karst waters has natural factors - interaction between water and marbles. It was found that the waters are unsaturated to carbonate minerals, which proves that even now there are active processes of karst formation.
To combat the shortage of single agro-residue and overcome the problem of seasonal availability, it is beneficial to use mixture of lignocellulosic biomasses. In the present study, efforts were made ...to use mixed lignocellulosic biomass for production of bioethanol, along with microbial lipids and lactic acid. Upon enzymatic hydrolysis of mixed biomass at varied proportions it was observed that mixture of paddy straw and jute in the ratio 3:1 resulted in best sugar yield (41.50 g/L) at 10% substrate loading. Ethanolic fermentation of mixed substrate hydrolysate by thermotolerant yeast, Saccharomyces cerevisiae JRC6 resulted in 8.39 g/L of ethanol. To maintain sustainability and economic impact, oleaginous yeast (Trichosporon mycotoxinivorans S2) and lactic acid bacteria (Lactobacillus plantarum LP-9) were used for lipid production (14.5 g/L) and lactic acid production (11.08 g/L), respectively. Therefore, this study explored the potential of mixed lignocellulosic biomass to be exploited for production of various value-added products.
El partido de Cuenca era uno de los cuatro en que se agrupaban los ganaderos miembros del Concejo de la Mesta que eran vecinos de lugares de las sierras. Pero también incorporó ganaderos avecindados ...en lugares de las tierras llanas, en su mayoría ubicados en la actual provincia de Ciudad Real. En este artículo el autor analiza el comercio de las lanas producidas por los ganados trashumantes de los vecinos del ámbito serrano del partido, principalmente de Cuenca y Molina de Aragón con sus aldeas. Profundiza en la caracterización de dichas lanas, diferenciándolas de las bastas producidas por el ganado estante, e informa sobre su calidad y precio. Identifica a los mercaderes que comerciaron con ellas, y da cuenta de sus procedimientos de contratación y su influencia sobre los precios.
Coordination on the management of transboundary waters is crucial for the development of riparian regions; nevertheless, lack of common legislation frameworks and communication channels jeopardize ...any cooperation among transboundary parties. The paper investigates the progress that has been conducted before and after the implementation of European Union’s common water policies in the management of transboundary surface waters and groundwaters shared between Bulgaria and Greece. To do so, the latest derivatives of the Water Framework and Flood Directives’ implementation process in both countries are analysed and processed to identify the quality and quantity (floods) of the surface waters’ status on the three transboundary river basins’ which are shared between the two countries, as well as the quality status of the groundwater bodies located in the boundary area. The outputs are compared with identified problems and pressures that were reported in the transboundary area before the operational implementation of the Directives. In terms of surface waters, the research demonstrates a remarkable amelioration of the inflows’ quality status to the downstream river basins. The most significant problem is induced floods due to transboundary waters, however the recent activation of a cooperation mechanism is a very promising engagement. Finally, it has been established that the transboundary groundwater bodies are of good status, but additional groundwater formations are proposed to be designated as transboundary ones. Concluding, legislative and technical aspects of the EU water Directives have significantly fostered shared waters management in the case study area, with the proposed methodological framework to be applicable in all EU’s shared waters.
Preseljevanje s podeželja v mesta povzroča propadanje podeželja in prenapolnjenost mest. Glavno vprašanje, ki se pojavlja v zvezi s tem, je, kako se lahko mesta izognejo tej usodi in prestrežejo ...migrante na poti v mesta v iskanju boljših priložnosti. Razvoj turizma lahko ima osrednjo vlogo v razvoju podeželskih območij v Republiki Južna Afrika, in mesto Clarens je primer zgodbe o uspehu na tem področju. Avtorica v članku raziskuje, zakaj je turističnemu mestu, kot je Clarens, uspelo, drugim podobnim mestom pa ne. Podatki so bili zbrani s tremi vprašalniki za tri različne ciljne skupine, kar je omogočilo, da je bil v raziskavo vključen širok spekter déležnikov v turističnem miljeju Clarensa. Izsledki raziskave kažejo, da je pri spuščanju multinacionalk v majhna turistična mesta potrebna pazljivost, saj lahko te pokvarijo tamkajšnje vzdušje.
Weeds and ornamental plants serve as a reservoir for geminiviruses and contribute to their dissemination, genome recombination and/or satellite capture. Ornamental sunflower (Helianthus spp.) plants ...exhibiting mild leaf curl symptoms were subjected to begomovirus and DNA-satellites isolation. The full-length genome of the isolated begomovirus clone (Od1-A) showed 96.8% nucleotide (nt) sequence identity with mesta yellow vein mosaic virus (MeYVMV; accession no. FR772081) whereas, alphasatellite (Od1-a) and betasatellite (Od1-b) clones showed their highest nt sequence identities at 97.4% and 98.2% with ageratum enation alphasatellite (AEA; accession no. FR772085) and papaya leaf curl betasatellite (PaLCuB; accession. no. LN878112), respectively. The evolutionary relationships, average evolutionary divergence and the recombination events were also inferred. The MeYVMV exhibited 9.5% average evolutionary divergence and its CP and Rep had 9.3% and 12.2%, concomitantly; the alphasatellite and the betasatellite had 8.3% and 5.2%, respectively. The nt substitution rates (site-1 year−1) were found to be 6.983 × 10-04 and 5.702 × 10-05 in the CP and Rep of MeYVMV, respectively. The dN/dS ratio and the Tajima D value of MeYVMV CP demonstrated its possible role in host switching. The absolute quantification of the begomovirus demonstrated that mild symptoms might have a correlation with low virus titer. This is the first identification of MeYVMV and associated DNA-satellites from ornamental sunflower in Pakistan. The role of sequence divergence, recombination and importance of MeYVMV along with DNA-satellites in extending its host range is discussed.
Novejše raziskave na območju svetolucijske halštatske kulturne skupine, poimenovane tudi kot posoška skupina, ki je poseljevala razen zgornjega Posočja tudi Bohinjski kot, Cerkljansko in zgornjo ...dolino Nadiže, so pokazale, da je bila poseljenost mnogo gostejša, kot je bilo znano pred tem, kar zadeva predvsem sredogorje Julijskih Alp. Glede na doslej odkrite drobne najdbe sklepamo na poselitev teh predelov v kasnem obdobju svetolucijske skupine. V obdobju, ozna- čenem kot stopnja Sv. Lucija IIa–b, je opazen tudi gospodarski vzpon naselbine na Mostu na Soči kot protourbanega središča celotne kulturne skupine, ki je bila po vsej verjetnosti teritorialno organizirana. Na osnovi doslej opravljenih analiz nekropole na Mostu na Soči pa so predstavljeni na eni strani kazalci vplivov in stikov svetolucijske skupine s sosednjimi in tudi zelo oddaljenimi kraji oz. kulturnimi skupnostmi, na drugi strani pa indikatorji družbene strukturiranosti in diferenciranosti. Pomemben nov element v okviru ritualno-religiozne sfere pa predstavljajo arheološka najdišča v nenavadnih naravnih okoljih, za katere se ponuja razlaga o svetih krajih, kjer so se odvijali posebne vrste zaobljubni obredi. Na koncu je postavljeno tudi vprašanje o pismenosti in etnični pripadnosti svetolucijske halštatske skupnosti.
Data availability and the existence of exchange mechanisms are considered crucial issues for the management of water bodies shared among riparian countries. Moreover, common legislative and technical ...frameworks are assets that foster the management of transboundary waters in an integrated and sustainable manner. The River Basin Management Plans of the European Union’s Water Framework Directive implementation process not only incorporate a cooperative framework, but also include open access internet-based databases that can enhance cooperation and shed light on water-related conflicts among countries that share transboundary waters. The proposed methodological approach in this research is applied in four transboundary river basins, where Greece is the downstream country, and the upstream countries are not all member states of the European Union. The areas of dispute were found in the 2nd Water Convention Report. For each particular case study, data and information from the respective River Basin Management Plans were used to investigate the actual situation. The results demonstrated that significant conflict situations in the past, which involved both water quality and water quantity issues, could be resolved using continuous and reliable datasets included in the management plans. The use of freely available data sources renders the findings of this work useful for the sustainable management of shared waters.
