Integrated waste management as a climate change stabilisation wedge for the Maltese islands

The continuous increase in anthropogenic greenhouse gas emissions occurring since the Industrial Revolution is offering significant ecological challenges to Earth. These emissions are leading to climate changes which bring about extensive damage to communities, ecosystems and resources. The analysis in this article is focussed on the waste sector within the Maltese islands, which is the largest greenhouse gas emitter in the archipelago following the energy and transportation sectors. This work shows how integrated waste management, based on a life cycle assessment methodology, acts as an effective stabilisation wedge strategy for climate change. Ten different scenarios applicable to the Maltese municipal solid waste management sector are analysed. It is shown that the scenario that is most coherent with the stabilisation wedges strategy for the Maltese islands consists of 50% landfilling, 30% mechanical biological treatment and 20% recyclable waste export for recycling. It is calculated that 16.6Mt less CO2-e gases would be emitted over 50 years by means of this integrated waste management stabilisation wedge when compared to the business-as-usual scenario. These scientific results provide evidence in support of policy development in Malta that is implemented through legislation, economic instruments and other applicable tools.peer-reviewe

David, Prieur, and Robert: Artistic Architects of the French Revolution

In the absence of mass media and high literacy rates, art became a powerful tool for spreading revolutionary sentiment among the populace during the French Revolution. Hubert Robert, Jean-Louis Prieur, and Jacques-Louis David all employed varying levels of embellishment in their artistic creations in order to promote the Revolution. By analyzing the works of these three artists with three widely different scopes, the importance and impact of embellishment in patriotic artwork is fully revealed. The influence and objectives of Robert, Prieur, and David differed greatly and the level of embellishment that can be seen in their creations is affected by these notions. This implies that artists of the French Revolution were not only passive revolutionaries but instead, shaped the socio-political landscape through their talents.https://orb.binghamton.edu/research_days_posters_2024/1058/thumbnail.jp

Deep Brain Stimulation of the Subthalamic Nucleus Improves Reward-Based Decision-Learning in Parkinson's Disease

Recently, the subthalamic nucleus (STN) has been shown to be critically involved in decision-making, action selection, and motor control. Here we investigate the effect of deep brain stimulation (DBS) of the STN on reward-based decision-learning in patients diagnosed with Parkinson's disease (PD). We determined computational measures of outcome evaluation and reward prediction from PD patients who performed a probabilistic reward-based decision-learning task. In previous work, these measures covaried with activation in the nucleus caudatus (outcome evaluation during the early phases of learning) and the putamen (reward prediction during later phases of learning). We observed that stimulation of the STN motor regions in PD patients served to improve reward-based decision-learning, probably through its effect on activity in frontostriatal motor loops (prominently involving the putamen and, hence, reward prediction). In a subset of relatively younger patients with relatively shorter disease duration, the effects of DBS appeared to spread to more cognitive regions of the STN, benefiting loops that connect the caudate to various prefrontal areas importantfor outcome evaluation. These results highlight positive effects of STN stimulation on cognitive functions that may benefit PD patients in daily-life association-learning situations

Recurrent Syncope Triggered by Temporal Lobe Epilepsy: Ictal Bradycardia Syndrome

Ictal asystole is potentially lethal, and known to originate from the involvement of limbic autonomic regions. Appropriate treatment must include an antiepileptic drug and the implantation of a pacemaker. We report the case of a 54-year-old male with recurrent syncope secondary to ictal asystole triggered by temporal lobe epilepsy. This was confirmed by combined Holter and video-electroencephalogram monitoring

These lipids appear in conventional gas chromatograms as unresolved complex mixtures (UCMs) and include cyclic and acyclic biphytanes, C36-C39 derivatives of the biphytanes, and C31-C35 extended hopanes. Biphytane and extended hopanes are also found in high pressure catalytic hydrogenation (HPCH) products released from solvent-extracted sediments,indicating that archaea and bacteria were present in Late Archean sedimentary environments. Post-depositional, hydrothermal gold mineralization and graphite precipitation occurred prior to metamorphism (~2,665 Ma). Late Archean metamorphism significantly reduced the kerogen’s adsorptive capacity and severely restricted sediment porosity, limiting the potential for post-Archean additions of organic matter to the samples. Argillites exposed to hydrothermal gold mineralization have disproportionately high concentrations of extractable archaeal and bacterial lipids relative to what is releasable from their respective HPCH product and what is observed for argillites deposited away from these hydrothermal settings. The addition of these lipids to the sediments likely results from a Late Archean subsurface hydrothermal biosphere of archaea and bacteria.This project was supported by NASA Exobiology grant #NAG5-13446 to Fabien Kenig.

Because the constituents of UCMs are not ordinarily identified, a large amount of geochemical information is never explored. Gas chromatograms of saturated/unsaturated hydrocarbons extracted from Late Archean argillites and greywackes of the southern Abitibi Province of Ontario, Canada contain UCMs with different appearances or “topologies” relating to the intensity and retention time of the compounds comprising the UCMs. These topologies appear to have some level of stratigraphic organization, such that samples collected at any stratigraphic formation collectively are dominated by UCMs that either elute early- (within a window of C15-C20 of n-alkanes), early- to mid- (C15-C30 of n-alkanes), or have a broad UCM that extends through the entire retention time of the sample (from C15-C42 of n-alkanes). Comprehensive two-dimensional gas chromatography time-of-flight mass spectrometry (GC×GC-MS) was used to resolve the constituents forming these various UCMs. Early- to mid- eluting UCMs are dominated by configurational isomers of alkyl-substituted and non substituted polycyclic compounds that contain up to six rings. Late eluting UCMs are composed of C36-C40 mono-, bi-, and tricyclic archaeal isoprenoid diastereomers. Broad UCMs spanning the retention time of compound elution contain nearly the same compounds observed in the early-, mid-, and late retention time UCMs. Although the origin of the polycyclic compounds is unclear, the variations in the UCM topology appear to depend on the concentration of initial compound classes that have the potential to become isomerized. Isomerization of these constituents may have resulted from hydrothermal alteration of organic matter.This project was supported by NASA Exobiology grant #NAG5-13446 to Fabien Kenig.

Law and Policy Resource Guide: A Survey of Eminent Domain Law in Texas and the Nation

Eminent Domain is the power of the government or quasi-government entities to take private or public property interests through condemnation. Eminent Domain has been a significant issue since 1879 when, in the case of Boom Company v. Patterson, the Supreme Court first acknowledged that the power of eminent domain may be delegated by state legislatures to agencies and non-governmental entities. Thus, the era of legal takings began. Though an important legal dispute then, more recently eminent domain has blossomed into an enduring contentious social and political problem throughout the United States. The Fifth Amendment to the United States Constitution states, “nor shall private property be taken for public use, without just compensation.” Thus, in the wake of the now infamous decision in Kelo v. City of New London, where the Court upheld the taking of private property for purely economic benefit as a “public use,” the requirement of “just compensation” stands as the primary defender of constitutionally protected liberty under the federal constitution. In response to Kelo, many state legislatures passed a variety of eminent domain reforms specifically tailoring what qualifies as a public use and how just compensation should be calculated. Texas landowners recognize that the state’s population is growing at a rapid pace. There is an increasing need for more land and resources such as energy and transportation. But, private property rights are equally important, especially in Texas, and must be protected as well. Eminent domain and the condemnation process is not a willing buyer and willing seller transition; it is a legally forced sale. Therefore, it is necessary to consider further improvements to the laws that govern the use of eminent domain so Texas landowners can have more assurance that this process is fair and respectful of their private property rights when they are forced to relinquish their land. This report compiles statutes and information from the other forty-nine states to illustrate how they address key eminent domain issues. Further, this report endeavors to provide a neutral third voice in Texas to strike a more appropriate balance between individual’s property rights and the need for increased economic development. This report breaks down eminent domain into seven major topics that, in addition to Texas, seemed to be similar in many of the other states. These categories are: (1) Awarding of Attorneys’ Fee; (2) Compensation and Valuation; (3) Procedure Prior to Suit; (4) Condemnation Procedure; (5) What Cannot be Condemned; (6) Public Use & Authority to Condemn; and (7) Abandonment. In analyzing these seven categories, this report does not seek to advance a particular interest but only to provide information on how Texas law differs from other states. This report lays out trends seen across other states that are either similar or dissimilar to Texas, and additionally, discusses interesting and unique laws employed by other states that may be of interest to Texas policy makers. Our research found three dominant categories which tend to be major issues across the country: (1) the awarding of attorneys’ fees; (2) the valuation and measurement of just compensation; and (3) procedure prior to suit

Combining biomarker and bulk compositional gradient analysis to assess reservoir connectivity

The definitive version was published in Organic Geochemistry 41 (2010): 812-821, doi:10.1016/j.orggeochem.2010.05.003.Hydraulic connectivity of petroleum reservoirs represents one of the biggest uncertainties for both oil production and petroleum system studies. Here, a geochemical analysis involving bulk and detailed measures of crude oil composition is shown to constrain connectivity more tightly than is possible with conventional methods. Three crude oils collected from different depths in a single well exhibit large gradients in viscosity, density, and asphaltene content. Crude oil samples are collected with a wireline sampling tool providing samples from well‐defined locations and relatively free of contamination by drilling fluids; the known provenance of these samples minimizes uncertainties in the subsequent analysis. The detailed chemical composition of almost the entire crude oil is determined by use of comprehensive two‐dimensional gas chromatography (GC×GC) to interrogate the nonpolar fraction and negative ion electrospray ionization Fourier transform ion cyclotron resonance mass spectrometry (ESI FT‐ICR MS) to interrogate the polar fraction. The simultaneous presence of 25‐ norhopanes and mildly altered normal and isoprenoid alkanes is detected, suggesting that the reservoir has experienced multiple charges and contains a mixture of oils biodegraded to different extents. The gradient in asphaltene concentration is explained by an equilibrium model considering only gravitational segregation of asphaltene nanoaggregates; this grading can be responsible for the observed variation in viscosity. Combining these analyses yields a consistent picture of a connected reservoir in which the observed viscosity variation originates from gravitational segregation of asphaltene nanoaggregates in a crude oil with high asphaltene concentration resulting from multiple charges, including one charge that suffered severe biodegradation. Observation of these gradients having appropriate magnitudes suggests good reservoir connectivity with greater confidence than is possible with traditional techniques alone.The mass spectrometry work was supported by the NSF Division of Materials Research through DMR‐06‐54118, and the State of Florida
