Optimisation Of Accelerated Solvent Extraction Of Antioxidant Compounds From Rosemary (Rosmarinus Officinalis L.), Marjoram (Origanum Majorana L.) And Oregano (Origanum Vulgare L.) Using Response Surface Methodology, M. Hossain, Catherine Barry-Ryan, Ana Belen Martin-Diana, N. Brunton

Articles

The present study optimised the accelerated solvent extraction (ASE) conditions (Dionex ASE® 200, USA) to maximise the antioxidant capacity of the extracts from three spices of Lamiaceae family; rosemary, oregano and marjoram. Optimised conditions with regard to extraction temperature (66–129 °C) and solvent concentration (32–88% methanol) were identified using response surface methodology (RSM). For all three spices results showed that 129 °C was the optimum temperature in order to obtain extracts with high antioxidant activity. Optimal methanol concentrations with respect to the antioxidant activity of rosemary and marjoram extracts were 56% and 57% respectively. Oregano showed a different response to …

Citizenship And Worldwide Taxation: Citizenship As An Administrable Proxy For Domicile, Edward A. Zelinsky

Articles

The United States' worldwide taxation of its citizens is less different from international, residence-based norms than is widely believed and is sensible as a matter of tax policy. An individual's citizenship is an administrable, if sometimes overly broad, proxy for his domicile, his permanent home. Both citizenship and domicile measure an individual's permanent allegiance rather than his immediate physical presence. Because citizenship and domicile resemble each other, and because other nations often define residence for tax purposes as domicile, the U.S. system of citizenship-based taxation typically reaches the same results as the residence-based systems of these other nations, but reaches …

Some Experiences, Thoughts, Ideas And Open Questions Relating To Applied Thermodynamics, Jim Mcgovern

Articles

In this paper I present some of my thoughts and experiences relating to 'applied thermodynamics' over my career so far. I explain my interest in thermodynamics, describe some topics I have worked on, point out some questions that appear still to be open and outline some ideas for work that could be done. I describe how I was inspired to pursue the area of applied thermodynamics, with reference to a glass, opposed-piston internal combustion engine. I put my heat pump research in the late 1970s briefly into today's context. Some of my research has been in relation to compressors, which …

Embodied Emissions Abatement: A Policy Assessment Using Stochastic Analysis, Adolf Acquaye, Aidan Duffy, Biswajit Basu

Articles

Policymakers traditionally focus on regulating operational energy use in buildings, ignoring other life cycle components such as embodied energy even though this may account for a significant portion of life cycle emissions. Data relating to embodied energy and emissions in buildings is limited. However, stochastic techniques can be used to estimate the distribution of such emissions from buildings. This helps policymakers identify which instruments are appropriate for achieving emissions reductions. A primary aim of this paper is to demonstrate this approach using a sample of apartment buildings in Ireland. A Monte-Carlo simulation suggests that the average probability distribution of embodied …

Comparison Of Subcellular Responses For The Evaluation And Prediction Of The Chemotherapeutic Response To Cisplatin In Lung Adenocarcinoma Using Raman Spectroscopy, Haq Nawaz, Franck Bonnier, Aidan Meade, Fiona Lyng, Hugh Byrne

Articles

Confocal Raman Micro spectroscopy (CRM) is employed to examine the chemical and physiological effects of anticancer agents, using cisplatin and A549 adenocarcinoma cells as a model compound and test system respectively. Spectral responses of the membrane and cytoplasm of the cell are analysed independently and the results are compared to previously reported spectroscopic studies of the nucleus. Moreover, Raman spectra from the proteins extracted from the control and exposed samples are acquired and analysed to confirm the origin of the molecular changes of the cell membrane and cytoplasm of the A549 cells. Multivariate data analysis techniques including Principal Component Analysis …

An Evaluation Of The Community Childcare Subvention Scheme Using Policy Design Theory, Bernie O'Donoghue Hynes, Noirin Hayes

Articles

This paper utilises Policy Design Theory to evaluate policy tool design and selection in Ireland in order to look beyond policy goals and rhetoric to the meanings and assumptions within policy design. A review of the Community Childcare Subvention Scheme (CCSS) reveals it to be an ‘incentive’ tool that is structured around a negative social construction of the target populations as ‘dependants’ with little capacity to solve their own problems. While immediate policy objectives are met through the design of the CCSS, if viewed in a wider context of overall national policy objectives a range of negative side-effects are evident …

Using The Ipad For Reference Services, Megan Lotts, Stephanie Graves

Articles

The article looks at the use of iPad for reference services at Morris Library at Southern Illinois University-Carbondale. It says that these devices have allowed librarians to access information, such as a call number, without asking a student to find and log into a desktop. iPads have also provided mobility to the librarians assigned to virtual reference service. However, librarians have reported that they are uncomfortable using the iPad as a replacement for a traditional laptop, while some of them are concerned about the fragility of the touch screen.

Culinary Voices: Perspectives From Dublin Restaurants, Máirtín Mac Con Iomaire

Articles

Despite growing interest in culinary history and gastronomy in the last three decades, the use of oral history within the culinary field remains in an embryonic stage. By discussing the strength of oral history, particularly when triangulated with other sources, and surveying some food related projects, the article focuses on the power of oral history to capture the life experiences of chefs, waiters, restaurateurs and diners. The article calls on curators of culinary libraries to build oral history archives which can be accessed electronically.

Irish Corned Beef: A Culinary History, Máirtín Mac Con Iomaire, Pádraic Óg Gallagher

Articles

This article proposes that a better knowledge of culinary history enriches all culinary stakeholders. The article will discuss the origins and history of corned beef in Irish cuisine and culture. It outlines how cattle have been central to the ancient Irish way of life for centuries, but were cherished more for their milk than their meat. In the early modern period, with the decline in the power of the Gaelic lords, cattle became and economic commodity that was exported to England. The Cattle Acts of 1663 and 1667 affected the export trade of live cattle and led to a growing …

Generational Stages In Family Firms: Expanding The Database - Kosovo, Matthew C. Sonfield, Robert N. Lussier, Robert J. Barbato

Articles

Expanding the authors’ international database of family businesses, this investigation compared first, second and third-generation family businesses in a sample from Kosovo. Both supporting and challenging the existing literature, the findings indicate that, as family businesses move from first to second to third generation, almost all managerial characteristics, activities and practices remain the same. Implications are presented for theory development, for further research, and for those who manage or advise family businesses.

Result of a simulation study will be reported to correct this problem.

Synthesis And Characterization Of A Colloidal Novel Folic Acid–Β-Cyclodextrin Conjugate For Targeted Drug Delivery, Antonio Clementi, Maria Chiara Aversa, Carmelo Corsaro, Jeroen Spooren, Rosanna Stancanelli, Christine O'Connor, Mary Mcnamara, Antonino Mazzaglia

Articles

A novel folic acid–b-cyclodextrin (b-CD) conjugate was synthesized and preliminarily characterized by 1H NMR, ESI-MS, and MALDI-MS. 1H NMR shows the presence of a- and c-conjugates which are generated by b-CD linkage in turn with both carboxylic functions of folic acid. Moreover ROESY evidences supramolecular interactions between the benzene ring of the folic acid and the b-CD cavity. DOSY suggests that ethylenediamine derived b-CD–folic acid forms a colloidal dispersion difficult to purify from free folic acid. An analysis of self-diffusion coefficient (Ds) of the three species (a-, c-conjugates, and free folic acid) and relaxation times (T1 and T2) is reported …

Legal Positivism As An Idea About Morality, Martin J. Stone

Articles

I ask what a proper critical target for 'legal positivism' might be. I argue that utilitarian moral theory, and more generally fully directive moral theories, are unacknowledged motivations for legal positivism. Contemporary debate about 'the nature of law' is, historically speaking, much more of a footnote to utilitarianism than has been recognized.

The Impact Of Ashcroft V. Iqbal On Pleading, Alexander A. Reinert

Articles

The article critically examines the Supreme Court’s decision in *Ashcroft v. Iqbal*, which extended the plausibility pleading standard to all civil actions, and argues that this ruling has led to significant inconsistencies in lower court applications, raised Seventh Amendment concerns, and potentially excluded meritorious cases from judicial review. The analysis emphasizes the need for clarity and uniformity in pleading standards while proposing reforms to align the plausibility standard with constitutional and procedural fairness principles.

Does Qualified Immunity Matter?, Alexander A. Reinert

Articles

In litigation brought pursuant to Bivens v. Six Unknown Named Agents of the Fed. Bureau of Narcotics, 403 U.S. 388 (1971), most commentators agree that qualified immunity plays a substantial role in limiting plaintiffs' ability to recover compensation. Many find this tradeoff acceptable, in part because of concerns of fairness to government official defendants and in part because courts may still play a central role in announcing the law without worrying over the retroactive effect their decision will have on the personal funds of the defendant official.

This paper considers the different role that qualified immunity may play in …

Stochastic Hybrid Embodied Co2-Eq Analysis: An Application To The Irish Apartment Building Sector, Adolf Acquaye, Aidan Duffy, Biswajit Basu

Articles

Although embodiedCO2-eq analysis has seen recent developments as evident in the establishment of the ISO14040 and 14044 LCA standards, it is recognized that due to weaknesses in gathering data on product-related emissions,embodiedCO2-eq values are probabilistic. This paper presents a stochastic analysis of hybrid embodied CO2-eq in buildings to account for this weakness in traditional methods and, by way of example, applies it to an Irish construction-sector case study. Using seven apartment buildings, 70,000 results are simulated with Monte Carlo analysis and used to derive probabilistic and cumulative embodied CO2-eq intensity distributions for apartment buildings in Ireland. A Wakeby distribution with …

Identification Of ‘Carbon Hot-Spots’ And Quantification 1 Of Ghg Intensities In The Biodiesel Supply Chain Using Hybrid Lca And Structural Path Analysis, Adolf Acquaye, Thomas Wiedmann, Kuishang Feng, Robert Crawford, John Barrett, Johan Kuylenstierna, Aidan Duffy, Lenny Koh, Simon Mcqueen-Mason

Articles

It is expected that biodiesel production in the EU will remain the dominant contributor as part of a 10% minimum binding target for biofuel in transportation fuel by 2020 within the 20% renewable energy target in the overall EU energy mix. Life cycle assessments (LCA) of biodiesel to evaluate its environmental impacts have, however, remained questionable, mainly because of the adoption of a traditional process analysis approach resulting in system boundary truncation and because of issues regarding the impacts of land use change and N2O emissions from fertiliser application. In this study, a hybrid LCA methodology is used to evaluate …

Revisiting Soil C And N Sampling: Quantitative Pits Vs. Rotary Cores, Benjamin M. Rau, April M. Melvin, Dale W. Johnson, Christine L. Goodale, Robert R. Blank, Guinevere Fredriksen, Watkins W. Miller, James D. Murphy, Donald E. Todd Jr., Roger F. Walker

Articles

Increasing atmospheric carbon dioxide and its feedbacks with global climate have sparked renewed interest in quantifying ecosystem carbon (C) budgets, including quantifying belowground pools. Belowground nutrient budgets require accurate estimates of soil mass, coarse fragment content, and nutrient concentrations. It has long been thought that the most accurate measurement of soil mass and coarse fragment content has come from excavating quantitative soil pits. However, this methodology is labor intensive and time consuming. We propose that diamond-tipped rotary cores are an acceptable if not superior alternative to quantitative soil pits for the measurement of soil mass, coarse fragment content, C and …

Development And Characterisation Of Integrated Microfluidics On Waveguide-Based Photonic Platforms Fabricated From Hybrid Materials, Robert Copperwhite, Mary O'Sullivan, Catherine Boothman, Arnaud Gorin, Colette Mcdonagh, Mohamed Oubaha

Articles

This article reports on a detailed investigation of sol–gel processed hybrid organic–inorganic materials for use in lab-on-a-chip (LoC) applications. A particular focus on this research was the implementation of integrated microfluidic circuitry in waveguide-based photonic sensing platforms. This objective is not possible using other fabrication technologies that are typically used for microfluidic platforms. Significant results on the surface characterisation of hybrid sol–gel processed materials have been obtained which highlight the ability to tune the hydrophilicity of the materials by careful adjustment of material constituents and processing conditions. A proof-of-principle microfluidic platform was designed and a fabrication process was established which …

Impact Of Technostress On End-User Satisfaction And Performance, Monideepa Tarafdar, Qiang Tu, T. Ragu-Nathan

Articles

Organizational use of information and communications technologies (ICT) is increasingly resulting in negative cognitions in individuals, such as information overload and interruptions. Recent literature has encapsulated these cognitions in the concept of technostress, which is stress caused by an inability to cope with the demands of organizational computer usage. Given the critical role of the user in organizational information processing and accomplishing application-enabled workflows, understanding how these cognitions affect users’ satisfaction with ICT and their performance in ICT-mediated tasks is an important step in appropriating benefits from current computing environments. The objective of this paper is to (1) understand the …

Unbundling Risk, Lee Anne Fennell

Articles

Scholars have explored many ways to rearrange risk outside of traditional insurance markets. An interesting literature addresses a range of innovative alternatives, including the sale of unmatured tort claims or chances at windfalls, "anti-insurance," or "reverse insurance," and index-based derivatives that address routine (but life-altering) risks, such as those to home values or livelihoods. Because most of this work grows out of a conviction that specific risk allocations embedded in law could be improved upon, the merits of the newly proposed risk arrangements have taken center stage. This Article, in contrast, examines questions surrounding risk customization itself such as the …

Buying From Secondary Markets: Acquiring Dollars And Sense, Julie Mosbo, John Ballestro

Articles

Between 2004 and 2008, Morris Library’s monographic budget was reduced by over $400,000 representing a fifty percent reduc- tion. The increase in serial prices forced the shifting of monograph funds to the serials budget. Despite this shift, the increase in serials costs, combined with an otherwise flat budget, resulted in two serials’ cancellation projects in a span of four years.

Faced with these economic realities, the acquisitions unit at Southern Illinois University’s Morris Library has sought alternative schemas to save money. One decision was to consider purchas- ing materials from secondary and used-book sources. For fiscal year 2009, a database …

The Role Of Authority, Scott A. Hershovitz

Articles

The most influential account of authority – Joseph Raz's service conception – is an account of the role of authority, in that it is an account of its point or function. However, authority does not have a characteristic role to play, and even if it did, the ability to play a role is not, by itself, sufficient to establish authority. The aim of this essay is to shift our focus from roles that authority plays to roles that people play – which we can also call roles of authority – such as chef, teacher, and parent. To justify authority, we …

Quantitative Assessment Of The Shelf-Life Of Ozonated Apple Juice, Sonal Patil, Vasilis Valdramidis, Brijesh Tiwari, Patrick J. Cullen, Paula Bourke

Articles

Sterile apple juice inoculated with S. cerevisiae ATCC 9763 (10³ CFU/mL) was processed in a bubble column with gaseous ozone of flow rate of 0.12 L/min and concentration of 33-40 µg/mL for 8 min. The growth kinetics of S. cerevisiae as an indicator of juice spoilage was monitored at 4, 8, 12 and 16 ºC for up to 30 days. The kinetics were quantitatively described by the primary model of Baranyi and Robert’s and the maximum specific growth rate was further modeled as a function of temperature by the Ratkowsky type model. The developed model was successfully validated for …

Maternal Health Behaviours During Pregnancy In An Irish Obstetric Population And Their Assocations With Socio-Demographic And Infant Characteristics, Roslyn Tarrant, Katherine Younger, Margaret Sheridan-Pereira, John Kearney

Articles

Objectives: To examine the prevalence and combined occurrence of peri-conceptional folic acid (FA) supplement use, smoking and alcohol consumption during pregnancy in a sample of women in Dublin, and determine the factors associated with these health behaviours.

Subjects/Methods: A prospective observational study (2004-2006) involving the recruitment of 491 pregnant women from antenatal clinics in a Dublin maternity hospital, with postpartum follow-up of 450 eligible mothers. Data on FA use, maternal smoking and alcohol consumption patterns during pregnancy were collected from the antenatal patient-administered questionnaire, which was completed by participants, and returned to the investigator on the day of recruitment. …

Multifluid Magnetohydrodynamic Turbulent Decay, Turlough Downes, Stephen O'Sullivan

Articles

It is generally believed that turbulence has a significant impact on the dynamics and evolution of molecular clouds and the star formation that occurs within them. Non-ideal magnetohydrodynamic (MHD) effects are known to influence the nature of this turbulence. We present the results of a suite of 5123 resolution simulations of the decay of initially super-Alfv enic and supersonic fully multifluid MHD turbulence. We find that ambipolar diffusion increases the rate of decay of the turbulence while the Hall effect has virtually no impact. The decay of the kinetic energy can be fitted as a power law in time and …

Thermal Bridging - Understanding Its Critical Role In Energy Efficiency, Joseph Little, Beñat Arregi

Articles

Plane element heat loss[1] and thermal bridging[2] together constitute all the conduction heat loss (measured in W/K, watts per kelvin) through the thermal envelope[3] of a building. Perversely insulating the plane elements more and more without carefully dealing with junctions can lead to a significant increase in thermal bridging heat loss. This is often more significant in poorly thought-out energy-focused retrofits than in existing or new buildings.
