Hydrodiplomacy is the emerging framework where legal acts, based on technical data and information, aim to support commonly accepted solutions to water-related tensions among states with ...transboundary waters. In this research, hydrodiplomacy components in relation to (a) policy, (b) preventive, (c) cooperative, and (d) technical aspects are considered together with climate change, which is bound to destabilize the core element of hydrodiplomacy, i.e., water. The study area is composed of the five transboundary river basins of Greece. The coupling of all these different nature elements is conducted with the use of the AHP multicriteria method, and the results of a normalized output that quantifies water transboundary cooperation in the climate crisis era are given.
Onesnaženost zraka v urbanih območjih je pomemben dejavnik kakovosti življenja, nesporen pa je tudi vpliv kakovosti zraka na zdravje ljudi. Med pomembna onesnaževala urbanega ozračja že desetletja ...uvrščamo dušikov dioksid (NO2), po letu 2000 pa se vse več raziskav posveča tudi črnemu ogljiku (BC). V prispevku predstavljamo stacionarne in mobilne meritve črnega ogljika ter stacionarne meritve dušikovega dioksida v urbanem območju na dveh primerih. V prvem primeru gre za ugotavljanje vpliva ceste na kakovost zraka v neposredni okolici vrtca in nekdanje osnovne šole na Lavrici, v drugem primeru pa so prikazani rezultati meritev črnega ogljika na cestnem omrežju Kranja v gosti prostorski mreži.
A thermally bonded biodegradable fabric has been developed using mesta and polylactic acid fibers. The central composite rotatable design has been adapted to understand the effects of the independent ...variables, that is polylactic acid content, roller temperature and roller pressure on useful functional properties such as bursting strength, bending load, tensile stress relaxation, tensile creep, rate of absorption, absorption capacity, porosity, abrasion resistance, and surface friction. Considering the linear, quadratic, and two-way interactive effects of independent variables, the second-order polynomial has been suggested for each property which proves good association except for absorption capacity and abrasion resistance. The effect of independent parameters has been studied and optimized from contour diagrams. The optimized process parameters for 140 g/m2 fabric are polylactic acid content 30%, mesta content 70%, roller temperature 170°C, and roller pressure 150 N/cm2, which can be used successfully as a shopping bag. The shopping bag was prepared from developed fabric. Its performance test shows no deformation for up to 14 days in the hanging test, resistance up to 10 wetting-drying cycles proves reusability, it sustains up to four drops, and has a slight strength loss in 30 days of atmospheric exposure.
Demografski podatki in podatki o razpoložljivosti kapacitet domov starejših občanov (DSO) v Sloveniji nakazujejo potrebo po spremembi organiziranosti tega segmenta varstva. V prispevku smo se ...osredotočili na analizo in vrednotenje stanja urejenosti in dostopnosti zelenih površin ter storitev splošnega pomena v majhnih mestih z vidika potreb starejših prebivalcev, ki svojo starost preživljajo v DSO. Hkrati smo ocenili možnosti za dejansko uporabo zelenih površin te skupine prebivalstva. Ugotovili smo, da v Sloveniji potrebujemo temeljite sistemske spremembe na področju institucionalnega varstva starejših občanov, tudi na področju zagotavljanja, urejenosti in uporabe zelenih površin ob DSO.
Prostor posoške skupnosti iz starejše železne dobe (8.–4. st. pr. n. št.), znane kot svetolucijska halštatska kulturna skupina, zaznamujejo različne geomorfološke značilnosti in naravne ...danosti. Najstarejše jedro stalne poselitve se je izoblikovalo ob naravnih poteh, ki vodijo ob Nadiži in Soči iz Furlanske nižine oz. iz zaledja severnega Jadrana v alpski visokogorski svet.
O stalni poselitvi na začetku železne dobe pričajo predvsem grobišča, medtem ko je v naseljih zaradi skromne raziskanosti starejše obdobje (8.–6. st. pr. n. št.) slabše prepoznavno. Grobovi iz starejših faz kažejo na manjše lokalne skupnosti, grobni pridatki pa ne izražajo večjih družbenih razlik. Družbeno razslojevanje je zaznavno v mlajših fazah (6. do 4. st. pr. n. št.), ko se ob prevladujočem pokopu sežganih ostankov v preprosto grobno jamo, pokrito s kamnito ploščo, poja- vijo tudi maloštevilni žarni grobovi v obliki kamnite skrinje in z bogatejšimi pridatki. V mlajšem obdobju je naselje na Mostu na Soči doseglo največji obseg in se razvilo v glavno regionalno središče z zgodnjeurbanimi značilnostmi. V 6. in 5. st. pr. n. št. je opazna tudi ekspanzija te skupnosti, zrasla so nova manjša naselja. Večinoma so bila deloma utrjena, v neutrjenih bi lahko videli naselja drugega ranga. V 4. st. pr. n. št. so sledili pretresi in spremembe, ki so privedli do dezintegracije skupnosti. Prebivalstvo se je iz starih aglomeracij umaknilo v stranske doline in bolj hribovite predele, v grobnih in daritvenih obredjih pa je v znatnejši meri prisotno orožje.
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.
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.
