Management Contracts

Bottom-up solutions for managing the territory have been increase their importance in the last years. Local communities want to be involved in the management of the territory to avoid problems and to promote economic and social activities. Several different forms of participatory contracts have been developed during the last decades. However, a framework to enforce each single solution are required. The Territorial Management Contracts (TMCs) would like to give a contribute in such a direction. The contribute briefly illustrates the Territorial Management Contracts, to open a debate on them.

The recent development of new generation LPRO or nanofiltration membranes have received attraction for application in the field of wastewater and water treatment through an increasingly stringent regulation for drinking purpose and water reclamation. In this research, the application on treatment of anionic pollutants (nitrate, nitrite, phosphate, sulfate and chloride ions) have been investigated as functions of transmembrane pressure, crossflow velocity and temperature under very much lower pressure operation range (0.49 to 0.03 MPa) than any other previous research used to do. Negative rejection was also observed under very much low range of operating pressure in the case of membrane type NTR-7250. Moreover, the extended Nernst-Planck model was used for analysis of the experimental data of the rejection of nitrate, nitrite and chloride ions in single solution by considering effective charged density of the membranes.

In this chapter, we describe how highly erratic dynamic behavior can arise from a nonlinear logistic map, and how this apparently random behavior is governed by a surprising order. With this lesson in mind, we should not be overly surprised that highly erratic and random appearing observed data might also be generated by parsimonious deterministic dynamic systems. At a minimum, we contend that researchers should apply NLTS to test for this possibility. We also introduced tools to analyze dynamic behavior that form the foundation for NLTS. In particular, we have stressed the quite unexpected capability to achieve some form of predictability even with only one trajectory at hand. In subsequent chapters, we treat known nonlinear dynamical systems as unknown, and investigate how NLTS methods rely on a single solution (or multiple solutions) generated by them to reconstruct equivalent systems. This is a conventional approach in the literature for seeing how NLTS methods work since we know what needs to be reconstructed.

Taking Action

With changing consumption patterns, growing populations and increased urbanisation, developing countries face significant challenges with regards to waste management. Waste plastic is a particularly problematic one, with single-use plastic leaking into the environment, including the marine environment, at an unprecedented rate. Around the world, countries are taking action to minimise these impacts, including banning single-use plastics; changing petroleum-based plastics to alternative bio-benign products such as paper, glass or biodegradable plastics; and improving waste collection systems to ensure that all waste is appropriately collected and reprocessed or safely disposed. However, these “solutions” are often met with resistance, from business, government or civil society, due to the intended and unintended consequences, leaving many questioning the most appropriate solution to reducing the leakage. This paper argues that there is no one single solution to addressing the leakage of plastic into the environment, but that the solution is likely to be a combination of the three approaches, based on local considerations.

Intergenerational transmission of disadvantage remains a problem despite political and educational initiatives. This study explored the role of personality and psychosocial factors in occupational status in a survey of 383 participants (174 males and 209 females) over 39 years from age 16 to 55. Mother’s education, extraversion, and mastery motivation were the best predictors of current socioeconomic status. A focus on education and academic development as the single solution to social immobility has been ineffective. Instead a broader approach which includes realistic lifelong educational opportunities and an education system which enables socioemotional development as well as academic growth is recommended.

Abstract A 5-well rig-less & explosiveness abandonment campaign by 2 project partners operator and service provider was made a reality in Morocco whereby a novel method of cementing squeeze of perforations and an annular fill-up were established in one single operation. This is called LEAN abandonment and the method was masterminded as a result of intense collaboration between both partners. The method is scale-able and has full merit to target existing legacy wells for abandonment in Morocco and world-wide where appropriate. In this LEAN approach the tubing and annulus were communicating via SSD / non-explosive created tubing punch by holding backpressure on the annulus till perforations squeezed or pressure lock-up and subsequently immediately opening the annulus and releasing the annular pressure whilst continuing pumping and filling the annulus with some 800 m of cement creating the firm additional barrier. Clinical planning by operator and service provider on a establishing a new abandonment process that is opening-up further in-country and beyond opportunities was the critical success factors in this work. It led to organic improvement on a well by well basis in the campaign, it resulted in safe and successful operations and achieving abandonment objectives cementing to surface in tubing and annulus. LEAN Abandonment forms a paradigm shift. It may be different in different down-hole settings and there is no single solution however like in our case working a bottoms-up approach has resulted the lowest cost solution and having done so ways to improve overall safety and efficiency were identified. The use of non-explosive technology is a very good example.

Abstract In the present paper, a new uncertainty analysis-based framework for data-driven computational mechanics (DDCM) is established. Compared with its practical classical counterpart, the distinctive feature of this framework is that uncertainty analysis is introduced into the corresponding problem formulation explicitly. Instated of only focusing on a single solution in phase space, a solution set is sought for in order to account for the influence of the multi-source uncertainties associated with the data set on the data-driven solutions. An illustrative example provided shows that the proposed framework is not only conceptually new, but also has the potential of circumventing the intrinsic numerical difficulties pertaining to the classical DDCM framework.

It is not known how life originated. It is thought that prebiotic processes were able to synthesize short random polymers. However, then, how do short-chain molecules spontaneously grow longer? Also, how would random chains grow more informational and become autocatalytic (i.e., increasing their own concentrations)? We study the folding and binding of random sequences of hydrophobic (H) and polar (P) monomers in a computational model. We find that even short hydrophobic polar (HP) chains can collapse into relatively compact structures, exposing hydrophobic surfaces. In this way, they act as primitive versions of today’s protein catalysts, elongating other such HP polymers as ribosomes would now do. Such foldamer catalysts are shown to form an autocatalytic set, through which short chains grow into longer chains that have particular sequences. An attractive feature of this model is that it does not overconverge to a single solution; it gives ensembles that could further evolve under selection. This mechanism describes how specific sequences and conformations could contribute to the chemistry-to-biology (CTB) transition.

The 2008 Financial Crisis

For the past five decades, hundreds of unfinished public works have been erected in Italy as the result of inconsistent planning and the presence of corruption and organised crime. A third of these constructions are located in Sicily alone, and so, in 2007, a group of artists labelled this phenomenon an architectural style: ‘ Incompiuto Siciliano’. Through this creative approach, the artists’ objective is to put incompletion back on the agenda by viewing it from a heritage perspective. This article reviews the different approaches that the artists have envisaged to handle unfinished public works; whether to finish them, demolish them, leave them as they are or opt for an ‘active’ arrested decay. The critical implications of these strategies are analysed in order to, ultimately, conclude that incompletion is such a vast and complex issue that it will surely have more than one single solution; but rather a combination of these four. This is important because it opens up a debate on the broad spectrum of possibilities to tackle incompletion – establishing this as one of the key contemporary urban themes not only in Italy but also in those countries affected by unfinished geographies after the 2008 financial crisis.
