Independent of the level of their development, national economies mostly bear the burden of regional inequalities and, grosso modo, of the existence of regions that fall behind in development. These regions are most vulnerable in post communist and highly centralized countries such as Croatia and the Czech Republic. Croatia and Czech Republic share many similarities, for example transitional post-communist background with centralized national economies dominated by capital city regions. Considering this, the aim of this paper is to analyse regions in Croatia with respect to their economic and social development with a detailed review of the least developed region. With that in mind, a comparative display of Czech Republic and issues concerning Czech lagging regions in economic aand social development will be used to find the common denominator with similar problems in Croatian regions followed by suggestions for solutions on a regional level. This paper uses methods of description and comparative anaysis, wih an analytical review of data made available by relevant institutions.","PeriodicalId":87252,"journal":{"name":"European scientific journal","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86669150","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}

So energy is considered one of the biggest priorities and challenges facing the world economy due to the lack of conventional energy sources of crude oil and natural gas used in energy generation. The use of thermal insulation materials in building's envelope is one of the ways to reduce energy consumption. Therefore, this study will address the importance of the use of thermal insulation materials in building' envelope to reduce energy loss as a result of heating and cooling conditions. The case sudy was the implementation of thermal insulation on Engineering Faculty building's envelope/ Muta'h University. The thermal loads were calculated for the building, with and without thermal insulation, by using four common different insulation materials which are; Rockwool, foam concert, double-glazing and extended Polystyrene. The selection of these materials depends on availability in the market, cost of implementation and the coefficient of thermal conductivity. The results showed that the polystyrene extended of thickness 10 cm is the best material for the thermal insulation in comparison of the others. The reduction ratio in thermal transmittance reached up to 76%; while in volume ratio of central heating fuel consumption reached up to 26.7%.","PeriodicalId":87252,"journal":{"name":"European scientific journal","volume":"2 1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78654257","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}

The increased ethnic diversification occuring across many larger urban areas has somewhat altered this dynamic. Chicago, Illionois is one major city possessing a long history of being highly segregated residentially. The city is especially noted for the exceptionally high levels of separation that have always existed between African-Americans and whites. Like many major cities the last few years, it has increasingly became home to larger numbers of Hispanics and Asians, a trend that has altared its residential geography. This research investigates the impacts that increased diversity had on levels of residential segregation among racial and/or ethnic groups within Chicago from 2000 to 2010. Empirical analysis entailed the measurement of two dimensions of segregation evident among Non-Hispanic whites, African-Americans, Hispanics and Asians. We focus particular attention to the role that segregation has in terms of influencing degrees to which these different groups are exsposed to poverty residentially. During the decade, African-American Chicagoans as a group became slightly less residentially isolated. Conversely, results confirm that both Asians, and Hispanics appear to be exhibiting forms of “ethnic (or racial) self-selectivity” that functioned to spatially concentrate them within their own neighborhoods. The demographic composition of the city’s extremly poor neighborhoods changed during the decade, yet they remained predominantly black. Findings lead us to conclude that in 2010 Chicago was still a highly segregated, albeit increasingly diverse, city.","PeriodicalId":87252,"journal":{"name":"European scientific journal","volume":"11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88718290","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}

In a previous paper, we singled out the DCL company’s environmental policies, as well as the cruise itinerary waste management plans for the enterprise’s ships. The paper analyses the in-house environmental personnel’s activity, the company’s internal regulations, and relevant data and field observations collected by the environmental protection staff, and presents data on the collection, sorting and storage of the waste generated by DCL cruise ships, and details food waste processing and discharge methods. The paper confirms the DCL company’s intention to minimize its fleet’s environmental impact by implementing the appropriate waste collection, sorting and storage methods, as well as by reducing food waste amounts and ensuring an efficient food waste management. In 2013, DCL was declared the most environmentally-responsible cruise line, according to the Cruise Industry Environmental Report Card. All crew members are charged with complying with environmental requirements and DCL’s environmental policy. Both crew members and customers must pay attention to practices that can accidentally result in food waste pollution. Food waste collection and the prevention of improper overboard spillage of waste are carefully supervised by everyone on board. The DCL company makes constant efforts to reduce food waste amounts and associated risks to a minimum across its commercial fleet. This entails using proper waste storage and disposal procedures, as well as planning the supply of raw materials and food ingredients","PeriodicalId":87252,"journal":{"name":"European scientific journal","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87699051","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}

Millsp.) is an important drought tolerant legume cultivated in the semi-arid regions, mainly in Sub-Saharan Africa. Despites its important potential, the crop is neglected and underutilized in many countries including Benin. In order to develop efficient in-situ strategies conservation, a study was conducted to quantify pigeon pea landrace diversity and access its spatial distribution and traditional management by local communities in southern Benin. Therefore, an ethnobotanical survey was conducted in 20 producing villages in southern Benin. Altogether, 26 farmernamed landraces further grouped into five categories were recorded with the number of landraces really cultivated per farmer comparably lower than that listed. Besides, two landraces’ categories were found to be common in the study area while two other were found highly threatened. Diverse parameters such as varietal richness, Shannon-Weaver Diversity Index, Simpson index and Pielou’s evenness were used to quantify pigeon pea diversity that appeared to be unequally distributed through the different agro-ecologies and villages surveyed. The study confirmed the absence of correlations between farmers’ gender and landrace diversity which was nonetheless found to be significantly shaped by the ethnic group and the field size exploited by farmers (P < 0.05). In diversity management, five preference criteria with variable importance across the ethnic groups were used by farmers of which cooking time and market value appeared to be the most important. Exhaustive germplasm collections, morphological/molecular characterizations of these landraces are required for efficient conservation of this important but neglected crop genetic resource in Benin.","PeriodicalId":87252,"journal":{"name":"European scientific journal","volume":"412 1","pages":"184-184"},"PeriodicalIF":0.0,"publicationDate":"2018-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78096013","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}

CSR communication contributes to a corporation’s corporate social disclosure, whose main purpose is to enhance a corporate image in order to promote customer and community relations and indirectly promote products to customers. To reach this goal, transparency is crucial. However transparency in the field of CSR is a difficult matter for two reasons: there is not uniformity in social reporting and the preparation of this document is not mandatory. The research is divided into two sections and the approach used is mainly descriptive: in the first part the concept of social balance as a means to interact with all the stakeholders of a firm is exposed. In the second part the paper analyses the web sites of a panel of selected listed Italian companies. The data are able to demonstrate that the size of the company still represent a barrier to CSR reporting and communication since require efforts and investment in term of time and resources. The research also shows that those company identified as “best practice” in the selected panel have a common strength: they attach an importan role to CSR in their corporate websites as a way to improve their image from the perspective of the multiple stakeholders.","PeriodicalId":87252,"journal":{"name":"European scientific journal","volume":"12 1","pages":"17-25"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90020595","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}

The aim of this work was to evaluate the contact toxicity of Pennyroyal mint (Mentha pulegium), oregano (Origanum compactum) and thyme (Thymus capitatus) essential oils against adults, larvae and eggs of two-spotted spider mite Tetranychus urticae Koch (Tetranychidae). The chemical composition of these three plant essential oils was also characterized. Laboratory tests were conducted to determine the acaricidal effect of plant essential oils at several doses in geometric progression. The consequences of treatments on mortality were measured in relationships with concentrations of essential oils. On the other hand, the major constituents of the three essential oils were identified by gas chromatography-mass spectrometer (GC-MS) techniques. GCMS analyses proved that the major compound present in the essential oils of thyme and oregano is carvacrol (55.59 and 55.28% respectively) while the main component of pennyroyal mint essential oil is pulegone (67,63%). Laboratory bioassay results indicated that essential oils of thyme and pennyroyal mint caused the most important acaricidal effects in comparison with the essential oil of oregano. At a concentration of 1%, thyme and pennyroyal eradicate all adults of the mite while oregano causes a mortality of 84.99%. On larvae, the mortality rate of thyme, pennyroyal and oregano is 97.7; 89.47 and 57.89% respectively. The results of the present study concluded that plant essential oils could be useful in promoting research aiming at the development of new agent for pest control from the plants with medicinal values.","PeriodicalId":87252,"journal":{"name":"European scientific journal","volume":"41 1","pages":"118-118"},"PeriodicalIF":0.0,"publicationDate":"2018-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80155082","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}
