New Books Network Podcast - C.J. Alvarez, A History of Construction on the US-Mexico Divide
No full textRecent debates over the building of a border wall on the U.S.-Mexico divide have raised logistical and ethical issues, leaving the historical record of border building uninvoked. A recent book, written by UT Austin professor Dr. C.J. Alvarez, offers an over one-hundred-year history that extends to before the building of a border wall in 1990. Border Land, Border Water: A History of Construction on the US-Mexico Divide (University of Texas Press, 2019) recounts the history of how both US and Mexican government agencies surveyed, organized, and operationalized land and water from 1848 until 2009. By centering the relationship between government agencies and border policing, Alvarez clearly shows how construction and manipulation of the border space’s natural features maintained the political and geographical form of the nation-state, how it reproduced the notion of the border space as something needing to be controlled and dominated, and how it transformed the border space into one of economic possibility and growth. The history of construction and hydraulic engineering on the divide is largely about the opposing forces of border building to keep certain people and things out, and border building to let certain things in. Alvarez lays bare this tension between tactical infrastructure and trade infrastructure both as forces that have organized border life. During the 1960s and 70s, “the ports of entry began to embody the ever-deepening contradictions embedded in policies designed to accelerate sanctioned economic exchange on the one hand while seeking to decelerate black market commerce on the other,” Alvarez writes (143). By the turn of the 21st century, Alvarez argues, most of the police construction on the border was designed to manage the negative effects of previous building projects and policies. In regards to the completion of the 2009 border fence, Alvarez writes, “It was overbuilding designed to compensate for an unsustainable immigration system, unsustainable ‘drug wars,’ and an unsustainable politics of scapegoating noncitizens. Far more successful at achieving its stated goals, however, was the infrastructure of cross-border commerce” (222). Dr. Alvarez utilizes extensive government records from the binational agency International Boundary and Water Commission (IBWC)/ Comisión Internacional de Límites y Aguas (CILA), records from Army Corps of Engineers, the INS, and the prodigious W.D. Smithers photograph collection from the Harry Ransom Center. The number of photographs included in the manuscript shows the vastness of the US-Mexico divide's natural landscape, shows how agencies attempted to make sense of such vastness, and shows what they constructed. Border Land, Border Water is a must-read for historians of the US-Mexico divide, environmental historians, and anyone interested in better understanding from a historical perspective current calls construction on the border.Office of the VP for Researc

Co-digestion of the mechanically recovered organic fraction of municipal solid waste with slaughterhouse wastes
No full textThe current work aimed to resolve some long-standing questions about the potential benefits and limitations of co-digestion of slaughterhouse wastes. To achieve this, a laboratory-scale trial was carried out using the mechanically recovered organic fraction of municipal solid waste mixed with either sheep blood or a mixture of pig intestines with flotation fat. Both of these co-substrates are difficult to digest in isolation because of their high nitrogen and lipid concentrations, and are regulated as Category 3 materials under the Animal By-Products Regulations (EC 1069/2009). The results showed that at an organic loading rate of 2 kg VS m?3 day?1 with the slaughterhouse material making up 20% of the load on a volatile solids basis the process could operate successfully. As the loading was increased to 4 kg VS m?3 day?1 signs of inhibition appeared with both co-substrates, however, and volumetric methane production was reduced to a point where co-digestion gave no process advantage. The main operational problem encountered was an increase in the concentration of volatile fatty acids in the digestate, particularly propionic acid: this was thought to be a result of ammonia toxicity. The concentration of potentially toxic elements in the digestate made it unsuitable for agricultural application for food production, although the increased nitrogen content made it more valuable as a fertiliser for non-food crop use

The Actors' Perceptions and Expectations of their Roles in BIM-based Collaboration
No full textThe inter-organisational collaboration with Building Information Modelling (BIM) is one of the hottest topics in construction sector nowadays. The implementation of BIM is a complex inter-organisational process, and the sharing of information among numerous actors from multi-disciplinary backgrounds may affect the actors’ role perception and performance. This study offers insights into the BIM roles of various actors by analysing a BIM-based project carried out by an integrated partnership across many tiers. The analysis identified inconsistencies between the actors' perceptions and their partners’ expectations of their BIM roles. Inconsistencies in BIM roles were more related to soft rather than hard (domain- or technical) skills. Mismatches were found in the architect's role, as it was deemed necessary to be more domain- and BIM-related, contrary to their perceptions. Likewise, the suppliers' role called for an enhanced BIM orientation. The paper concludes with set of suggestions for increasing the joint responsibility and supporting the multi-actor collaboration.Design & Construction ManagementSustainable Housing Transformatio
A pilot-scale trial comparing mesophilic and thermophilic digestion for the stabilisation of source segregated kitchen waste
No full textSource segregated food waste was collected from domestic properties and its composition determined together with the average weight produced per household, which was 2.91 kg per week. The waste was fed over a trial period lasting 58 weeks to an identical pair of 1.5 m3 anaerobic digesters, one at a mesophilic (36.5 oC) and the other at a thermophilic temperature (56 oC). The digesters were monitored daily for gas production, solids destruction and regularly for digestate characteristics including alkalinity, pH, volatile fatty acid (VFA) and ammonia concentrations. Both digesters showed high VFA and ammonia concentrations but in the mesophilic digester the pH remained stable at around 7.4, buffered by a high alkalinity of 13,000 mg l-1; whereas in the thermophilic digester VFA levels reached 45,000 mg l-1 causing a drop in pH and digester instability. In the mesophilic digester volatile solids (VS) destruction and specific gas yield were favourable, with 67% of the organic solids being converted to biogas at a methane content of 58% giving a biogas yield of 0.63 m3 kg-1 VS added. Digestion under thermophilic conditions showed potentially better VS destruction at 70% VS and a biogas yield of 0.67 m3 kg-1 VS added, but the shifts in alkalinity and the high VFA concentrations required a reduced loading to be applied. The maximum beneficial loading that could be achieved in the mesophilic digester was 4.0 kg VS m-3 d-1
