Response Surface Methodology Guided Release Of Two Acetate Volatiles From An Oil-In-Water Emulsion, Mark Traynor, Roisin Burke, N. Brunton, Catherine Barry-Ryan

Articles

Optimization of the volatile release of two commonly used flavor compounds (isoamyl acetate and furfuryl acetate) from a food emulsion model system was evaluated using response surface methodology (RSM). Twenty-seven random order settings were established using a central composite face-centered (CCF) experimental design. The main and combined effects of four independent variables—concentration of isoamyl acetate (50–90 ppm), furfuryl acetate (20–30 ppm), salt (NaCl; 0.1–2%), and pH (5–7)—on the responses were examined. The main objective of the present study was to determine the optimal concentration level of the four variables leading to optimal release of the volatile compounds. Quantitative measurements were …

Development of visible light active (VLA) titania photocatalysts

Fujishima and Honda (1972) demonstrated the potential of titanium dioxide (TiO 2) semiconductor mate-rials to split water into hydrogen and oxygen in a photo-electrochemical cell. Their work triggered the development of semiconductor photocatalysis for a wide range of environmental and energy applica-tions. One of the most significant scientific and commercial advances to date has been the development of visible light active (VLA) TiO2 photocatalytic materials. In this review, a background on TiO2 struc-ture, properties and electronic properties in photocatalysis is presented. The development of different strategies to modify TiO2 for the utilization …

Sales Between A Partnership And Non-Partners, Douglas A. Kahn

Articles

The code denies a deduction for a loss recognized on a sale or exchange between certain related parties. Two of the principal code sections that deny a deduction in that circumstance are sections 267(a)(1) and 707(b)(1)(A). Two regulatory provisions promulgated under section 267 apply the denial of a loss deduction rule to partnerships — reg. section 1.267(b)-1(b) and temp. reg. section 1.267(a)-2T(c), Question 2. I conclude that to the extent reg. section 1.267(b)-1(b) applies to section 267(a)(1), it is invalid and has been invalid since 1986. Also, two of the questions and answers in the temporary regulation are invalid.

Anti-Cancer Activity And Mutagenic Potential Of Novel Copper (Ii) Quinolinone Schiff Base Complexes In Hepatocarinoma Cells, Brian Duff, Venkat Reddy Thangella, Bernadette Creaven, Maureen Walsh, Denise Egan

Articles

This study determined the cytotoxic, cyto-selective and mutagenic potential of novel quinolinone Schiff base ligands and their corresponding copper(II) complexes in human-derived hepatic carcinoma cells (Hep-G2) and non-malignant human-derived hepatic cells (Chang). Results indicated that complexation of quinolinone Schiff bases with copper served to significantly enhance cytotoxicity. Here, the complex of (7E)-7-(3-ethoxy-2-hydroxybenzylideamino)-4-methylquinolin-2(1H)-one (TV117-FM) exhibited the lowest IC₅₀ value (17.9 μM) following 96 h continuous exposure, which was comparable to cisplatin (15.0 μM). However, results revealed that TV117-FM lacked cytoselectivity over non-malignant cells. Additionally, the complex was minimally effluxed from cells via Pglycoprotein (P-gp) and was shown to be non-mutagenic …

Rhyme Or Reason:That Is The Question?, Jim Roche

Articles

Noting that “the aesthetic should not be limited merely to the way things look” the organisers of this conference sought “in part to address the discursive limitation in architecture and related subjects by broadening the aesthetic discourse beyond questions relating to purely visual phenomena in order to include those derived from all facets of human experience”.

So where does etchics come in? Well, the introductory brochure noted that most philosophical trained aestheticians will say that “the aesthetic is everything” hinting perhaps of the necessity for a more haptic experience of architecture. It also drew on Wittgenstein’s quote that “ethics and …

The Latest Homebond House Building Manual : A Critique, Joseph Little

Articles

The Homebond House Building Manual had the distinction of being called the ‘bible’ for many building during the boom. It was a commonly‐used reference book, even for many builders and architects who never built housing estates and therefore had little need of a Homebond guarantee. One might design a construction detail of a dwelling differently, but one did it with an awareness of what the manual showed. It gave the insurance scheme great credibility and standing. This architect remembers reluctantly getting involved with an external wall insulation self‐build project in rural Ireland in 2006 (far beyond his normal travel distance) …

Proximity Study Of A Uwb Directional Conformal Antenna On Water Pipe, Domenico Gaetano, Max Ammann, Patrick Mcevoy, Matthias John, Louise Keating, Frances Horgan

Articles

A preliminary study on the conformal properties of an antipodal exponentially tapered antenna placed on the surface of a flow meter system in the UWB range is presented. It was observed that the water effect can be mitigated by shifting the antenna away from the pipe surface.

Comparative Review Of Imaging Methods Used For Diagnosing Renal Artery Stenosis (Ras), Deirdre King, Carmel Moran, Jacinta Browne

Articles

This comparative review examines the efficacy of different imaging methods to detect and quantify renal artery stenosis (RAS). Detection of RAS is important because it can lead to renovascular hypertension which is the most common form of secondary hypertension. Furthermore, it is important that a RAS is detected as early as possible as it is a potentially correctable cause of hypertension.¹ If detected at an early stage RAS can potentially be treated using a minimally invasive drug treatment regimen rather than the more invasive percutaneous transluminal renal angioplasty without or with stent placement or surgery. Currently there are a …

Clinical Applicability Of The Macular Degeneration Detection Device (Mdd-2): A Novel Photostress Recovery Measurement Device, James Loughman, Ciara Hewitt, Claire Judge, Louise Martin, Claire Moulds, Peter Davison

Articles

Background: Diseases affecting the macula, such as age-related macular degeneration (AMD), diabetic retinopathy and central serous retinopathy can result in impaired photostress recovery time (PSRT) despite normal visual acuity and fundoscopic appearance. The MDD-2 Macular Degeneration Detection Device is a novel flash photostress recovery device. In this study, we examine the repeatability of the MDD-2 in a normal population and its suitability for incorporation into routine clinical practice. Methods: One hundred (60 female) subjects (mean age 35+-8 years; range 18 to 66 years) were recruited to partake in this study. The photostress recovery time was measured using the MDD-2 on …

Inhibition Of Burkholderia Multivorans Adhesion To Lung Epithelial Cells By Bivalent Lactosides, Ciara Wight, Rosaria Leyden, Paul V. Murphy, Máire Callaghan, Trinidad Velasco-Torrijos, Siobhan Mcclean

Articles

Burkholderia cepacia complex (Bcc) is an opportunistic pathogen in cystic fibrosis patients which is inherently resistant to antimicrobial agents. The mechanisms of attachment and pathogenesis of Bcc, a group of 17 species, are poorly understood. The most commonly identified Bcc species in newly colonised patients, Burkholderia multivorans, continues to be acquired from the environment. Development of therapies which can prevent or reduce the risk of colonization on exposure to Bcc in the environment would be a better alternative to antimicrobial agents. Previously, it has been shown that Bcc strains bound to many glycolipid receptors on lung epithelia. Using a …

Contribution Of A Built-In Loss To A Partnership, Douglas A. Kahn

Before 2004, it was possible to use the partnership tax provisions of the code to shift the benefit ofa loss deduction for a decline in property valuefrom the person who incurred it to another person.One method of accomplishing that goal involvedthe contribution of depreciated property to a partnership.

Students Fail To Transfer Knowledge Of Chromosome Structure To Topics Pertaining To Cell Division, Dina L. Newman, Christina M. Catavero, Leslie Kate Wright

Articles

Cellular processes that rely on knowledge of molecular behavior are difficult for students to comprehend. For example, thorough understanding of meiosis requires students to integrate several complex concepts related to chromosome structure and function. Using a grounded theory approach, we have unified classroom observations, assessment data, and in-depth interviews under the theory of knowledge transfer to explain student difficulties with concepts related to chromosomal behavior. In this paper, we show that students typically understand basic chromosome structure but do not activate cognitive resources that would allow them to explain macromolecular phenomena (e.g., homologous pairing during meiosis). To improve understanding of …

Concentrated Flow Erodibility For Physically Based Erosion Models: Temporal Variability In Disturbed And Undisturbed Rangelands, Osama Z. Al-Hamdan, Frederick B. Pierson, Mark A. Nearing, C. Jason Williams, Jeffry J. Stone, Patrick R. Kormos, Jan Boll, Mark A. Weltz

Articles

Current physically based overland flow erosion models for rangeland application do not separate disturbed and undisturbed conditions in modeling concentrated flow erosion. In this study, concentrated flow simulations on disturbed and undisturbed rangelands were used to estimate the erodibility and to evaluate the performance of linear and power law equations that describe the relationship between erosion rate and several hydraulic parameters. None of the hydraulic parameters consistently predicted the detachment capacity well for all sites, however, stream power performed better than most of other hydraulic parameters. Using power law functions did not improve the detachment relation with respect to that …

Retirees Beware: Don't Worry About The British-- 2013 Is Coming, Douglas A. Kahn, Lawrence W. Waggoner

Articles

Retirees beware. The easy money policy of the Federal Open Market Committee and the 15 percent tax rate on qualified dividends have encouraaged retirees, especially middle-income retired savers, to reorient their nest eggs away from certificates of deposit, treasuries, and money market funds to dividend-paying stocks and mutual funds. According to the IRS, 43 percent of taxpayers age 65 or older reported qualified dividend income amounting to nearly half of the qualified dividend income reported by all taxpayers. By contrast, 46 percent of taxpayers age 65 or older reported net capital gains amounting to 30.5 percent of the net capital …

Our Broken Misdemeanor Justice System: Its Problems And Some Potential Solutions, Eve Brensike Primus

Articles

Although misdemeanors comprise an overwhelming majority of state criminal court cases, little judicial and scholarly attention has been focused on how misdemeanor courts actually operate. In her article, Misdemeanors, Alexandra Natapoff rights this wrong and explains how the low-visibility, highly discretionary decisions made by actors at the misdemeanor level often result in rampant discrimination, incredible inefficiency, and vast miscarriages of justice. Misdemeanors makes a significant contribution to the literature by refocusing attention on the importance of misdemeanor offenses and beginning an important dialogue about what steps should be taken going forward to fix our broken misdemeanor justice system.

A Coupled Mathematical Model For Simultaneous Microwave And Convective Drying Of Wheat Seeds, Mohamed Hemis, Ruplal Choudhary, Dennis G. Watson

Articles

Faster drying techniques are preferred to prevent spoilage of harvested wheat seeds. Microwave (MW) drying may be used as an alternate technique for faster drying of crops with efficient utilisation of time and energy. The objective of this study was to develop a mathematical model to simulate the drying condition of wheat seeds during drying in a MW oven. A coupled mathematical model was developed for simultaneous MW and convective drying of wheat seeds in a domestic MW oven, resulting in a system of non-linear equations. Wheat samples with initial moisture levels of 15e25% wet basis were dried under MW …

Developing Archetypes For Domestic Dwellings:An Irish Case Study, Albert Famuyibo, Aidan Duffy, Paul Strachan

Articles

Stock modelling, based on representative archetypes, is a promising tool for exploring areas for resource and emission reductions in the residential sector. The use of archetypes developed using detailed statistical analysis (multi-linear regression analysis, clustering and descriptive statistics) rather than traditional qualitative techniques allows a more accurate representation of the overall building stock variability in terms of geometric form, constructional materials and operation. This paper presents a methodology for the development of archetypes based on information from literature and a sample of detailed energy-related housing data. The methodology involves a literature review of studies to identify the most important variables …

Articles

The fabrication 1 and characterization of a 2 chalcogenide glass microsphere resonator has been demonstrated. 3 At wavelengths near 1550 nm, whispering gallery mode 4 resonances can be efficiently excited in a 74-μm-diameter 5 chalcogenide glass microsphere via evanescent coupling using a 6 tapered silica glass fiber with a waist diameter of circa 2 μm. 7 Resonances with Q-factors greater than 105 were observed. 8 Due to the high nonlinearity properties of the chalcogenide 9 material and the ease of fabrication process, chalcogenide 10 microspheres offer the potential for robustly assembled fully 11 integrated photonic devices. 12 Index Terms—Chalcogenide

Prisoner's Rights And The Separation Of Powers: Comparing Approaches In Ireland, Scotland And England And Wales., Mary Rogan

Articles

The decision of Hogan J in Kinsella v. Governor of Mountjoy Prison [2011] IEHC 235 (hereinafter Kinsella) is an important development in the protection of prisoners’ constitutional rights in Ireland. The decision, which found that a prisoner’s right to have his person protected had been breached by his detention in a padded cell with a cardboard box for use as a toilet in conditions amounting to a form of sensory deprivation, may represent a new direction for prison law jurisprudence. The judgment is also of significance for its analysis of the circumstances in which conditions of detention can give rise …

Revisiting "Special Needs" Theory Via Airport Searches, Alexander A. Reinert

Articles

Controversy has raged since the Transportation Security Administration (TSA) introduced Advanced Imaging Technology, capable of producing detailed images of travelers' bodies, and "enhanced" pat frisks as part of everyday airport travel. In the face of challenges in the courts and in public discourse, the TSA has justified the heightened security measures as a necessary means to prevent terrorist attacks. The purpose of this Essay is to situate the Fourth Amendment implications of the new regime within a broader historical context. Most germane, after the Federal Aviation Administration (FAA) introduced sweeping new screening of air travelers in the 1960s and 1970s …
