Yumurtacı Bıldırcınların Yemlerine Katılan Farklı Çinko Kaynaklarının Yumurta Eni Üzerine Etkisi
No full textBu çalışma, farklı çinko kaynaklarının yumurtacı bıldırcınlarda yumurta eni üzerine etkisinibelirlemek amacıyla yapılmıştır. Nanoteknoloji, maddeyi 1'den 100 nm'ye kadar olanboyutlarında benzersiz özellikleri ve özgün uygulamaları ile kullanan ve gelişen yeni birbilimdir. Bunlar yüksek sıcaklık ve basınç altında dengelidir, gastrointestinal sistem tarafındankolayca alınabilir ve canlılarda kullanılabilir. Dolayısıyla daha düşük dozlarda daha büyükboyutlu çinko oksitten (ZnO) daha etkilidir.Deneme gruplarında yumurta eni bakımından 4-6. haftalarda istatistiksel açıdan farklılık tespitedilmiştir (P>0.05). Çalışmanın 4-6 haftalarında en yüksek yumurta eni (mm) rasyona 6 mg/kgdüzeyinde inorganik ZnO ilave edilen grupta tespit edilmiştir (P>0.05). Rasyona farklı çinkokaynaklarının eklenmesi ile yapılan çalışmada denemenin 1. ve 2. haftalarında en düşükyumurta eni (mm) yemlerine bitki özütleri ile elde edilen 3 ve 6 mg/kg nano ZnO ilave edilengruplarda tespit edilmiştir (P>0.05). 3-6. Haftalarda ise en düşük yumurta eni yemlerine bitkiözütü ile elde edilen 6 mg/kg nano ZnO ilave edilen grupta tespit edilmiştir (P>0.05).Bıldırcın yemlerine farklı çinko kaynaklarının ilave edilmesi yumurta eni yemlerine 6 mg/kginorganik ZnO ilave edilmesi etki etmiştir fakat bitki özütü ile elde edilen nano ZnO etkisigörülmemiştir. This study was carried out to determine the effect of different zinc sources on egg width in layerquails. Nano-technology is a new emerging science that uses matter in sizes from 1 to 100 nmwith unique properties and unique applications. They are stable under high temperature andpressure and are readily uptake by the gastrointestinal tract and usable in vivo, thus moreeffective at lower doses than larger sized ZnO.A statistically significant difference was found between 1-6 weeks in terms of egg width in theexperimental groups (P>0.05). In the 1-6th weeks of the study, the highest egg width (mm) wasdetermined in the group with 6 mg/kg inorganic ZnO added to the ration (P>0.05). In the studyconducted with the addition of different sources of zinc to the ration, the lowest egg width (mm)was detected in the groups with the addition of 3 and 6 mg/kg nano ZnO obtained with plantextracts in the 1st and 2nd weeks of the experiment (P>0.05). At 3-6 weeks, the lowest eggwidth was detected in the group that added 6 mg/kg nano ZnO obtained with plant extract tothe feeds (P>0.05).Adding different sources of zinc to quail feeds and adding 6 mg/kg of inorganic ZnO to eggwidth feeds had an effect, but the effect of nano ZnO obtained with plant extract was notobserved.</p
Coupled PDE for Ultrasound Despeckling Using ENI Classification
No full textAbstractSpeckle is a type of noise which is often present in ultrasound images. Speckle is formed due to constructive or destructive interference of ultrasound waves. Due to the granular pattern of speckle noise, it hides important details in ultrasound images. Many despeckling techniques are proposed in the literature, but most of them fail to reach a balance between the removal of speckle noise and preservation of the fine details in the image. In this work, an improved coupled PDE model is proposed which combines second order selective degenerate diffusion (SDD) model and fourth order PDE model based on the assumption that speckle in ultrasound image follows Gamma distribution. An edge noise interior (ENI) method is used to control the diffusion. With the help of ENI controlling function, the diffusion at edge pixels and noisy pixels are selectively accomplished with varying speed. Thus, the proposed model preserves the edges and fine texture details in the image. The model is tested on simulated images after corrupting the images with various levels of Gamma noise. Further, we have tested it on real ultrasound images also. The performance of the proposed model is compared with other similar techniques and the proposed method outperforms other state-of-the-art methods, both in terms of qualitative and quantitative measures
Petrolio e Mezzogiorno. Lo sviluppo del Sud nel cinema industriale: il caso Eni (1960-1965)
No full textThe Eni (Ente nazionale idrocarburi), the oil and gas state ownes enterprise, founded by Enrico Mattei in 1953, has used many advertising communication’s strategies to diffuse its activities throughout the national territory and abroad. Among the many instruments that the company has used (billboards advertising on the road, magazines, newspapers, house organ “Il gatto selvatico”, television spots “Carosello”) there are also the documentaries that are seen in Italian cinemas. The author explores the representation that Eni gave the south of Italy in the years of the “miracolo economico” (economic miracle) with its industrial documentaries. Eni show himself as one of the key factors for economic and social development of southern Italy and resolve the “Questione meridionale”. The study of documentaries shows that while a country is moving towards modernity, still has problems of poverty and backwardness that even industrial progress can be solved, despite the company advertises itself as the motor of a new history for the Italy
Functional Cramér–Rao bounds and Stein estimators in Sobolev spaces, for Brownian motion and Cox processes
No full textWe investigate the problems of drift estimation for a shifted Brownian motion and intensity estimation for a Cox process on a finite interval [0,T], when the risk is given by the energy functional associated to some fractional Sobolev space H01⊂Wα,2⊂L2. In both situations, Cramér–Rao lower bounds are obtained, entailing in particular that no unbiased estimators (not necessarily adapted) with finite risk in H01 exist. By Malliavin calculus techniques, we also study super-efficient Stein type estimators (in the Gaussian case)
The Government and Civil Society roles in the CSR: the case of Poland
No full textPaper presented at the Third Core Conference: The potential of CSR to
drive integration in an enlarged Europe held in Nottingham, June 19-20, 2008Taking for granted that a joint action of all actors of the society is necessary to ensure sustainable development and human rights protection universally, and that State and civil society roles not only complement each other, but often overlap, this paper attempts to define the roles of the State and civil society in the area of CSR, focusing on Poland as a case study.
The role of State with regards to CSR is approached from a human rights perspective.
States are not only obliged to ensure that appropriate legislation protecting human
rights from abuse by business, is in place and is enforced, but also have an explicit duty under ratified treaties to promote human rights. The author argues that promoting CSR should be viewed as a way of contributing to a better realization and respect for human rights and therefore constitutes part of a State’s obligations.
Finally, the author provides a number of suggestions regarding State policies, strategy,‘leading by example’ approach and relevant institutional frameworks, which aim at encouraging CSR practices among companies and involve civil society organisations.
These, due to their very nature and purpose, could be a State’s natural ally in this quest, particularly in the area of multi-stakeholder engagement, ensuring mechanisms of verification and raising awareness.CORE is financed by the European Commission, Sixth Framework Programme and it is coordinated by Fondazione Eni Enrico Mattei (FEEM)
Information and modeling issues in designing water and sanitation subsidy schemes
No full textIn designing a rational scheme for subsidizing water services, it is important to support the choice of design parameters with empirical analysis that stimulates the impact of subsidy options on the target population. Otherwise, there is little guarantee that the subsidy program will meet its objectives. But such analysis is informationally demanding. Ideally, researchers should have access to a single, consistent data set containing household-level information on consumption, willingness to pay, and a range of socioeconomic characteristics. Such a comprehensive data set will rarely exist. The authors suggest overcoming this data deficiency by collating, and imaginatevily manipulating different sources of data to generate estimates of the missing variables. The most valuable sources of information, they explain, are likely to be the following: 1) Customer databases of the water company, which provide robust information on the measured consumption of formal customers, but little information on unmeasured consumption, informal customers, willingness to pay, or socioeconomic variables. 2) General socioeconomic household surveys, which are an excellent source of socioeconomic information, but tend to record water expenditure rather than physical consumption. 3) Willingness-to-pay surveys, which are generally tailored to a specific project, are very flexible, and may be the only source of willingness-to-pay data. However, they are expensive to undertake, and the information collected is based on hypothetical rather than real behavior. Where such surveys are unavailable, international benchmark values on willingness to pay may be used. Combining data sets requires some effort and creativity, and creates difficulties of its own. But once a suitable data set has been constructed, a simulation model can be created using simple spreadsheet software. The model used to design Panama's water subsidy proposal addressed these questions: a) What are the targeting properties of different eligibility criteria for the subsidy? b) How large should the subsidy be? c) How much will the subsidy scheme cost, including administrative costs? Armed with the above information, policymakers should be in a position to design a subsidy program that reaches the intended beneficiaries, provides them with the level of financial support that is strictly necessary, meets the overall budget restrictions, and does not waste an excessive amount of funding on administrative costs.Water Conservation,Environmental Economics&Policies,Health Economics&Finance,Economic Theory&Research,Decentralization,Water Supply and Sanitation Governance and Institutions,Economic Theory&Research,Environmental Economics&Policies,Town Water Supply and Sanitation,Health Economics&Finance

A Data Envelopment Analysis Approach to the Assessment of Natural Parks’ Economic Efficiency and Sustainability. The Case of Italian National Parks
No full textWilderness protection is a growing necessity for modern societies, and this is particularly true for areas where population density is extremely high, as for example Europe. Conservation, however, implies very high opportunity costs. It is thus crucial to create incentives to efficient management practices, to promote benchmarking and to improve conservation management. In the present paper we propose a methodology based on Data Envelopment Analysis, DEA, a non parametric benchmarking technique specifically developed to assess the relative efficiency of decision-making units. In particular, the objective of the discussed methodology is to assess the relative efficiency of the management units of the protected area and to indicate how it could be improved, by providing a set of guidelines. The main advantage of this methodology is that it allows to assess the efficiency of natural parks’ management not only internally (comparing the performance of the park to itself in time) but also by external benchmarking, thus providing new and different perspectives on potential improvements. Although the proposed methodology is fairly general, we have applied it to the context of Italian National Parks in order to produce a representative case study. Specifically, the choice of adequate cost and benefit indicators is a very important and delicate phase of any benchmark analysis. For this purpose, a questionnaire was used to investigate the opinions of Italian National Parks managers and stakeholders and to define the relevant indicators for the analysis. Finally, relevant policy implications for the case study are given.Data envelopment analysis, Natural park management
Processo de descolonização linguística e lusofonia
No full textIn this text, Eni Orlandi formulates the concept of linguistic descolonization: the imaginary imaginary in which takes place a linguistic event founded upon the fact that a language males sem se in relation to subjects that have been, bit are no more submitted to a power which imposes a language over subjects belonging to another society, State, Nation. The author analysies the process of linguistic decolonization in Brazil and proposes a turn in the relationship with Portugal and the other countries colonized by it through the resignification of the notion of "lusophony" towards decolonization.Eni Orlandi fórmula, neste texto, o conceito de descolonização linguística: o imaginário no Qual se dá um acontecimento linguístico sustentado no fato de que a língua faz sentido em relação a sujeitos que foram, mas não são mais submetidos a um poder que impõe uma língua sobre sujeitos de outra sociedade, Estado,Nação.
