Upgrading of Transmission Lines in Areas of Severe Environmental Constraints

The need for increasing the loading capacity of transmission lines in a traditional way, by replacing or reinforcement of the structures and foundations on routes crossing areas considered of permanent environmental preservation, may require additional works that alter the environment. The present rigorous environmental legislation turns these changes and substitution unfeasible. One way to increase the capacity of these lines is the use of new conductor technology. The aim of this paper is to discuss the needs for upgrading a transmission line and minimize or eliminate the damage to the environment by using special conductors. Because the aluminum conductor composite reinforced technology is relatively new and considering the lack of information related to its effective performance in practical system, there is a need to verify the behavior of these conductors through monitoring procedures.

What Happened to Participation? Urban Development and Authoritarian Upgrading in Cairo's Informal Neighbourhoods

Participation appeared in development discourses for the first time in the 1970s, as a generic call for the involvement of the poor in development initiatives. Over the last three decades, the initial perspectives on participation intended as a project method for poverty reduction have evolved into a coherent and articulated theoretical elaboration, in which participation figures among the paraphernalia of good governance promotion: participation has acquired the status of “new orthodoxy”. Nevertheless, the experience of the implementation of participatory approaches in development projects seemed to be in the majority of cases rather disappointing, since the transformative potential of ‘participation in development’ depends on a series of factors in which every project can actually differ from others: the ultimate aim of the approach promoted, its forms and contents and, last but not least, the socio-political context in which the participatory initiative is embedded. In Egypt, the signature of a project agreement between the Arab Republic of Egypt and the Federal Republic of Germany, in 1998, inaugurated a Participatory Urban Management Programme (PUMP) to be implemented in Greater Cairo by the German Technical Cooperation (Deutsche Gesellschaft für Technische Zusammenarbeit, GTZ) and the Ministry of Planning (now Ministry of Local Development) and the Governorates of Giza and Cairo as the main counterparts. Now, ten years after the beginning of the PUMP/PDP and close to its end (December 2010), it is possible to draw some conclusions about the scope, the significance and the effects of the participatory approach adopted by GTZ and appropriated by the Egyptian counterparts in dealing with the issue of informal areas and, more generally, of urban development. Our analysis follows three sets of questions: the first set regards the way ‘participation’ has been interpreted and concretised by PUMP and PDP. The second is about the emancipating potential of the ‘participatory approach’ and its ability to ‘empower’ the ‘marginalised’. The third focuses on one hand on the efficacy of GTZ strategy to lead to an improvement of the delivery service in informal areas (especially in terms of planning and policies), and on the other hand on the potential of GTZ development intervention to trigger an incremental process of ‘democratisation’ from below.

New catalytic processes for the upgrading of furfural and 5-hydroxymethylfurfural to chemicals and fuels

The demand of energy, fuels and chemicals is increasing due to the strong growth of some countries in the developing world and the development of the world economy. Unfortunately, the general picture derived sparked an exponential increase in crude oil prices with a consequent increase of the chemical, by-products and energy, depleting the global market. Nowadays biomass are the most promising alternative to fossil fuels for the production of chemicals and fuels. In this work, the development of three different catalytic processes for the valorization of biomass-derived has been investigated. 5-hydroxymethylfurfural oxidation was studied under mild reaction condition using gold and gold/copper based catalysts synthetized from pre-formed nanoparticles and supported onto TiO2 and CeO2. The analysis conducted on catalysts showed the formation of alloys gold/copper and a strong synergistic effect between the two metals. For this reason the bimetallic catalysts supported on titania showed a higher catalytic activity respect to the monometallic catalysts. The process for the production of 2,5-bishydroxymethyl furan (BHMF) was also optimized by means the 5-hydroxymethylfurfural hydrogenation using the Shvo complex. Complete conversion of HMF was achieved working at 90 °C and 10 bar of hydrogen. The complex was found to be re-usable for at least three catalytic cycles without suffering any type of deactivation. Finally, the hydrogenation of furfural and HMF was carried out, developing the process of hydrogen transfer by using MgO as a catalyst and methanol as a hydrogen donor. Quantitative yields to alcohols have been achieved in a few hours working in mild condition: 160 °C and at autogenous pressure. The only by-products formed were light products such as CO, CO2 and CH4 (products derived from methanol transformation), easily separable from the reaction solution depressurizing the reactor.

Analisi dell' upgrading di un impianto di digestione anaerobica: da biogas a biometano.

L'opera preliminarmente in una accurata analisi della configurazione e delle interrelazioni dei sistemi energetici presenti nello stabilimento produttivo Caviro Enomondo. Successivamente è svolto un approfondimento del quadro normativo relativo all’incentivazione delle fonti energetiche rinnovabili non fotovoltaiche e delle sue recenti evoluzioni, andando ad identificare tutte le possibili vie di sviluppo per impianti di produzione di biogas promosse a livello nazionale e che possono potenzialmente trovare applicazione nell’impianto in esame; questo studio è effettuato con particolare attenzione alla opportunità di effettuare un upgrading di tale impianto per realizzare ad una raffinazione totale o parziale del biogas a biometano. A seguito dell’identificazione della tipologia di prodotto e/o di processo che offre le migliori prospettive per una implementazione industriale e delle caratteristiche chimico-fisiche che questo deve rispecchiare, si prosegue quindi individuando lo schema impiantistico ottimale per adeguare l’attuale sistema di produzione al nuovo target. A seguire, approfondendo lo studio delle varie tecnologie disponibili ad oggi allo stato dell’arte, si identificano quelle maggiormente promettenti, mettendone in evidenza peculiarità positive e negative di ciascuna e giungendo alla identificazione della combinazione ottimale in termini di economicità, capacità produttiva, sicurezza ed impatto ambientale. Una volta individuate le caratteristiche di massima dell’impianto si procede ad un dimensionamento più accurato dello stesso andandone a valutare anche entità dei costi di investimento e di gestione. Attraverso l’instaurazione di contatti con ditte specializzate operanti nel settore industriale di riferimento, si giunge all’individuazione specifica dei modelli dei macchinari ed impianti richiesti. Il progetto si sviluppa successivamente andando a valutare le possibili modalità di utilizzo del prodotto finale che offrono maggiori prospettive di valorizzazione per l’azienda, identificando le varie soluzioni e gli interventi necessari per ciascuna di essa. La parte successiva dell’elaborato consiste in un confronto, in termini di valutazioni economiche, sull’opportunità di ognuna delle soluzioni prospettate, tenendo in considerazione i costi di investimento, di esercizio, i ricavi, e la componente incentivante. Si va infine a concludere il progetto proponendo una road-map per la realizzazione della soluzione che si evidenzia come la più promettente, con crono-programma degli interventi da eseguire, e aspettative di sviluppo a medio-lungo termine dell’investimento.

A Divergent Path of Industrial Upgrading: Emergence and Evolution of the Mobile Handset Industry in China

Starting from almost null in the late 1990s, China's mobile phone handset industry has grown to account for more than 40 percent of the current world production. While export growth has been overwhelmingly led by multi-national corporations (MNCs), increasingly fierce competition in the domestic market ignited by the advent of local handset makers has induced unique industrial evolution: (1) outgrowth of independent design houses specialized in handset development and (2) emergence of IC fabless ventures that design core ICs for handsets. In the background of this evolutionary industrial growth there are factors such as, the scale and increasing diversity of China's domestic market that advantages local firms vis-a-vis MNCs; modularization of handset and semiconductor technologies; policy interventions that supports local startups. The emergence and evolution of China's handset industry is likely to have international implications as the growth of the global demand for low-cost and multi-function mobile phone handsets is expected to accelerate. Thus, our case suggests that the conventional view of latecomer industrialization and upgrading that emphasizes the key role of international production networks organized by MNCs needs to be modified in order to accommodate China's rise into perspective.

Is the Vietnamese garment industry at a turning point? : upgrading from the export to the domestic market

Vietnam’s garment industry has been loosely characterized by the duality based on market orientation: export and domestic. Export-oriented garment suppliers were typically SOEs and foreign invested firms, while those producing for the domestic market have been mostly small, private companies. With a booming economy, other industrial sectors have emerged, and the garment industry is no longer the sector most favored by workers. Wage rates have been increasing, and a supplier’s ability to cope with this through successful upgrading has been the key determinant of whether it can further grow and flourish. Those who fail to cope are finding themselves in an increasingly difficult position. This paper looks at both the export- and domestic-oriented garment suppliers, and attempts to highlight how the industry can further develop by examining the bottlenecks that vary depending on the type of supplier. It suggests that in the long run, upgrading and value addition in the domestic market will be the key strategy.

Does trade liberalization boost quality upgrading? : evidence from Indonesian plant-product-level data

In this study, we examine the effects of tariff reduction on firms' quality upgrading by employing an Indonesian plant-product-level panel dataset matched with a plant-level dataset. We explore the effects of lower output and input tariffs separately, by focusing on the apparel industry. By estimating the Berry-type demand function, we derive product-quality indicators based on the Khandelwal (Review of Economic Studies, 2010) methodology, which enables us to isolate quality upgrading from changes in prices. Our findings are as follows. First, a reduction in output tariffs does not affect product quality upgrading. Second, a reduction in input tariffs boosts quality upgrading in general. In particular, this impact is greater for import firms, which is consistent with the fact that the source of the boost is the import of high-quality foreign inputs.

The UN General Assembly Vote: Upgrading the Status of Palestine and Its Implications for a Possible Role of the ICC. IES Policy Brief Issue 2013/06 • June 2013

On 29 November 2012, the General Assembly of the United Nations (UN) voted overwhelmingly to accord Palestine ‘Non-Member Observer State’ Status in the UN. In the first part of this Policy Brief, the implications of upgrading the status of Palestine with regard to the possible role of the International Criminal Court (ICC) will be assessed. In April 2012, the Office of the Prosecutor of the ICC declined to accept jurisdiction for acts committed on the territory of Palestine since 1 July 2002, justifying its decision based on the fact that Palestine had, at the time, only the status of an ‘Observer Entity’ at the UN. Subsequently, it will be analysed if the Palestinian pursuit of its cause before the ICC can be considered as an effective lawfare strategy or rather as a poisoned chalice.
