Chitosomes as drug delivery systems for C-phycocyanin: preparation and characterization.
2010
The aim of this work was to investigate chitosomes, i.e. liposomes coated by a polyelectrolyte complex between chitosan (CH) and xantan gum (XG), as potential delivery system for oral administration of the protein C-phycocyanin. To this purpose several CH-XG-microcomplexes were prepared in aqueous lactic acid at different chitosan-xanthan gum percent ratios and rheological properties of the microcomplexes were studied to analyse the contribution of chitosan and xanthan gum in the reaction of microcomplexation. After establishing the best microcomplexes, chitosomes were prepared by coating C-phycocyanin loaded liposomes with the CH-XG hydrogels using spray-drying or freeze-drying. The chitos…
The instability of the adjusted and unadjusted environmental Kuznets curves
2006
We test the stability of the unadjusted and adjusted environmental Kuznets curves (EKCs). Our results provide evidence in favour of a theoretically funded "adjusted EKC hypothesis" in which the impact of per capita GDP on CO2 emissions is evaluated conditionally to the effects of the industry mix and of the energy-supply infrastructure. In this specification, the shape of the GDP-CO2 relationship appears quite sensitive to changes in the estimation period. In the final part of the paper, signs and dynamics of fixed effects of individual countries in different specifications are interpreted as measures of virtuous or vicious of environmental behaviour. © 2006 Elsevier B.V.

LABOUR AND ECONOMIC GROWTH THROUGH EDUCATION AND RESEARCH IN LATVIA
2012
The structure of Latvian economy and distribution of employees within it during last years has changed. Dealing with study of population, one can find young people share continuous decline and labour mean age increase, but in situation of economic slowdown Latvia also face challenge to develop knowledge-based economy. One of the means of helping to achieve the goal of becoming competitive and knowledge-based economy is through an investment in human capital. To ensure sustainable development there is a need to balance between social and economical growth using available resources. The theoretical concepts have shown that further growth has to be built on innovation, diffusion and adoption o…
CREATION OF INNOVATIVE APPROACH FOR STUDY OF THE NATIONAL FISCAL SPACE
2017
The choice and topicality of the theme is substantiated by the fact that a sustainable development of a country is affected by the policy implemented by the government. One of its main parts is the fiscal or budget policy which means the formation of the necessary funds of the revenues and expenditures to ensure the functioning of the government. Accordingly, the concept of fiscal space has been activated which is closely connected with the implementation of the instruments of fiscal policy (taxes, government expenditures, government debt). The aim of the research is to create an innovative approach to the investigation of the creation of the state fiscal space applying the simulation metho…
Investment Policy Development and Problems in Latvia
2020
A promising investment compiling into a national economy is one of the main conditions that might influence positive changes of the state economical situation as well as local sustainable development and modern technologies advancement. Thus, financing private and public segments will boost the national economy and create possibilities to expand competitiveness of the whole country or its separate region.
NEITHER AUTHORIZED NOR PROHIBITED? SECESSION AND INTERNATIONAL LAW AFTER KOSOVO, SOUTH OSSETIA AND ABKHAZIA
2008
The flexibility mechanisms introduced by the Kyoto Protocol on climate change promote the realization of climate change related investment projects which aim to contribute both to the fight against climate change as well as to foster sustainable development patterns in host countries. At first glance, the flexibility mechanisms seem to represent paradigmatic examples of green economy instruments which have numerous potential benefits. However, the implementation of such mechanisms may give rise to some negative environmental externalities which have the consequence of creating a new type of investment versus environment conflict, characterized by a new form of conflict with an internal envi…
Renewable energy evaluation in Italy and Brazil
2017
The aim of this study is a comparison among Italian and Brazilian electrical energy system with a particular focus on renewable energy sources. The energy sector has a key role in the sustainable development of a country, so it influences economic and political choices. The work would underline differences, common point among two country, specially, in this particular socio-economic period and it should emphasize that green economy could be a possible answer to the financial crisis. The work will be divided into four sections: Section I will introduce all details of the question; Section II will explain the renewable assessments for the countries, Section III will talks how renewable energy…
Adoption of Green Environmental Practices in Small and Medium-Sized Enterprises: Entrepreneur and Business Policies Patterns in Romania
2021
Current research shows that SMEs’ social and environmental actions are fragmented and informal, and few have formal policies and intentions. At the same time, many SMEs are engaged with environmental policies, often not knowing it. Concurrently, there is a gap between the pro-environmental attitudes of the SMEs managers, who are often seen as the main drivers for the firm’s behavior, and the policies implemented in reality in their firms. To this end, our research’s objective is to explore pro-environmental behavior, both at the individual and firm level, to identify connections between these levels and measures but also with firm’s and managers’ demographics, based on a study of Romanian S…
Calls of the Jungle Crow (Corvus macrorhynchos s.l.) as a taxonomic character
2000
A discriminant analysis of the call structure completely separates threeCorvus taxa (levaillantii andjaponensis of the ‘macrorhynchos group’,splendens) inhabiting the southern slopes of the Himalayas (Nepal, Kashmir). The acoustic differences are considered taxonomically relevant, indicating species boundaries. Therefore the Jungle Crows of lower and upper Nepal (contact zone at around 2,000 m) are assigned to two biospecies (C. japonensis andC. levaillantii), as is consistent with morphological, ecological and parasitological data. It appears possible to extrapolate the findings regarding call structure to the systematics of other ‘macrorhynchos’ populations as distant as the Russian Far E…
Beryllium-induced disturbances of the murine immune system reflect some phenomena observed in sarcoidosis.
1994
Sarcoidosis is a systemic granulomatous disorder of unknown origin. In respect to clinical and immunological characteristics, it is indistinguishable from berylliosis. As an approach to develop a murine model reflecting some aspects of sarcoidosis, we attempted to induce berylliosis in mice by treating inbred F1 mice (C57B16 x DBA/2) with 3 mg beryllium sulfate (BeSO4) per kg body weight intraperitoneally. Either pure BeSO4 or BeSO4 in combination with incomplete Freund's adjuvant was administered. Alternatively, pure BeSO4 was injected 2 days after a single application of cyclophosphamide (150 mg/kg). The spleen index, the spontaneous and phorbolmyristate acetate (PMA)-induced radical oxyg…
