Determination Of Organophosphate Resistance-Dependent Over-Produce Esterase Allel Type With Electrophoresis In The Malaria Vector Species Anopheles Sacharovi And Culex Pipiens (Diptera: Culicidae), Ümi̇t Lüleyap, Davut Alpteki̇n, Hali̇l Kasap, Mülki̇ye Kasap

Turkish Journal of Biology

In this study, over-produce esterase allele types dependent on organophosphate resistance in mosquitoes were determined by cellulose acetate gel electrophoresis in the human malaria vector species Anopheles sacharovi and Culex pipiens in Çukurova (Adana). We found A_2 and A_5 allele bands with some unknown and unidentified gel bands in some An. sacharovi field samples, of which some bands seemed to match with over-produce esterase. We identified A_2-B_2 allele types for all the Cx. pipiens samples collected in this study.

Effects Of Endosulfan On The Isolated Sciatic Nerve Of The Frog, Ülkü Çömelekoğlu, Belgi̇n Büyükakilli, Aynur Avci Özge

Turkish Journal of Biology

The purpose of this study was to investigate the effect of endosulfan on the isolated sciatic nerve of the frog. The nerve was exposed to 0.5 ppm endosulfan for 60 min and then compound action potentials were recorded extracellulary. The latencies, amplitudes, durations of depolarization and repolarization and threshold voltage were measured (n=30). Conduction velocities were calculated using the nerve lengths and latency values of each nerve. It was observed that values of amplitude and duration of repolarization were significantly higher (p

Distance Spectra For Trellis Coded Modulation Schemes On Channels With Intersymbol Interference, Sabi̇re Haciömeroğlu, Melek D. Yücel

Turkish Journal of Electrical Engineering and Computer Sciences

The effect of intersymbol interference on distance spectra for trellis coded 8-PSK, 16-QAM and 32-AMPM modulation schemes is evaluated using the methods proposed by Schlegel. Distance spectra of 16-state 8-PSK scheme are computed for different intersymbol interference channels. It is seen that on channels with intersymbol interference the spectral lines are spread into a nearly continuous spectrum and the minimum Euclidean distance between codewords decreases severely. Hence, although the main contribution at large signal to noise ratios comes from the minimum Euclidean distance ( d_{free} ) , higher spectral components also become very important at moderate values of the signal …

Control Chart Pattern Recognition Using Artificial Neural Networks, Şeref Sağiroğlu, Erkan Beşdok, Mehmet Erler

Turkish Journal of Electrical Engineering and Computer Sciences

Precise and fast control chart pattern (CCP) recognition is important for monitoring process environments to achieve appropriate control and to produce high quality products. CCPs can exhibit six types of pattern: normal, cyclic, increasing trend, decreasing trend, upward shift and downward shift. Except for normal patterns, all other patterns indicate that the process being monitored is not functioning correctly and requires adjustment. This paper describes a new type of neural network for speeding up the training process and to compare three training algorithms in terms of speed, performance and parameter complexity for CCP recognition. The networks are multilayered perceptrons trained …

Rational Generalised Moonshine From Orbifolds, Rossen Ivanov, Michael Tuite

Articles

Frenkel, Lepowsky and Meurman constructed the Moonshine Module (MM) as a Z₂ orbifold of the Leech Lattice Meromorphic Conformal field theory. The group of automorphisms of this theory is the 'Monster Group' M - the largest finite sporadic simple group (with order ~ 8. 10⁵³ ). 'Monstrous Moonshine' is the famous observation that the Thompson series, corresponding to each class of M, is a hauptmodule for some genus zero fixing group. Norton considered Generalised Moonshine Functions (GMF), depending on two commuting Monster elements, and suggested that they are also hauptmodules. Using meromorphid Abelian orbifoldings of MM we identify …

Enantioselective Complexation Of Amino Acids By 6a-Deoxy-6a-Hydroxyethylamino- Β -Cyclodextrin And Its Metallo-Derivatives In Aqueous Solution, Nicole Van Hoof, Noel Russell, Mary Mcnamara, Raphael Darcy

Articles

Enantioselectivity towards several amino acids by metallo-6A-deoxy-6A-hydroxyethylamino-β-cyclodextrins (metallo- β CDea’s) was investigated by potentiometric titration of the various amino acid/metallo- β CDea systems with NaOH solution. It was shown that the cyclodextrin derivative is capable of distinguishing between enantiomers of amino acid species in the presence of certain metal ions (Co, Ni, Cu and Zn). Ni- β CDea complexes show the most enantioselectivity,whereas for Cu and Co2C-_CDea complexes less selectivity is observed. As expected, Zn- β CDea complexes exhibit no enantioselectivity. Stability and selectivity, however, do not go hand in hand, since the most stable complexes are formed …

Imagining Justice, Robin West

Georgetown Law Faculty Publications and Other Works

As we approach the new century and the new millennium, those of us who are legal professionals in liberal capitalist democracies need to drastically improve our practices of law if we are to bring those practices in line with our professed ideals. The commodification and marketing of legal services, for example, combined with a nearly blind commitment to overly combative advocacy, puts legal assistance beyond the means of large segments of the public, severely undercutting our commitment to equality before the law. A different and perhaps harder question, however, is whether the ideals against which we judge our practices are …

Abortions Of The Parental Prerogatives Of Unwed Natural Fathers: Deterring Lost Paternity, Jeffrey A. Parness

Faculty Articles, Papers, and Other Scholarship

A natural father's biological relationship with his child is often insufficient by itself to trigger the father's parental rights recognized within the "substantial protection" of the Due Process Clause of the Fourteenth Amendment or within comparable protections afforded by other federal or state laws. Rather, there is often required "an actual relationship" involving the assumption of parental responsibility, at least where there is no legal presumption of paternity or a certain affirmative act by an alleged natural father, like acknowledging paternity voluntarily. Determinations of actual relationships are frequently necessary and quite difficult where the natural father is not married to …

A Synoptic Climatology Of Derecho Producing Mesoscale Convective Systems In The North-Central Plains, M.L. Bentley, Thomas L. Mote, Stephen F. Byrd

Faculty Articles, Papers, and Other Scholarship

Synoptic-scale environments favourable for producing derechos, or widespread convectively induced windstorms, in the North-Central Plains are examined with the goal of providing pattern-recognition:diagnosis techniques. Fifteen derechos were identified across the North-Central Plains region during 1986–1995. The synoptic environment at the initiation, mid-point and decay of each derecho was then evaluated using surface, upper-air and National Center for Atmospheric Research (NCAR):National Center for Environmental Prediction (NCEP) reanalysis datasets. Results suggest that the synoptic environment is critical in maintaining derecho producing mesoscale convective systems (DMCSs). The synoptic environment in place downstream of the MCS initiation region determines the movement and potential strength …

A Java Graphical User Interface For Large-Scale Scientific Computations In Distributed Systems, X Shen, George K. Thiruvathukal, Wei-Keng Liao, Alok Choudhary, A Singh

Computer Science: Faculty Publications and Other Works

Large-scale scientific applications present great challenges to computational scientists in terms of obtaining high performance and in managing large datasets. These applications (most of which are simulations) may employ multiple techniques and resources in a heterogeneously distributed environment. Effective working in such an environment is crucial for modern large-scale simulations. In this paper, we present an integrated Java graphical user interface (IJ-GUI) that provides a control platform for managing complex programs and their large datasets easily. As far as performance is concerned, we present and evaluate our initial implementation of two optimization schemes: data replication and data prediction. Data replication …

Cellular Release Of And Response To Atp As Key Determinants Of The Set-Point Of Signal Transduction Pathways, Rennolds S. Ostrom, Caroline Gregorian, Paul A. Insel

Pharmacy Faculty Articles and Research

The determinants of “basal” activity of signaling pathways regulating cellular responses are poorly defined. One possibility is that cells release factors to establish the set-point of such pathways. Here we show that treatment of Madin-Darby canine kidney cells with the nucleotidase apyrase decreases basal arachidonic acid release and cAMP production 30–40% and that inhibitors of P2Y receptor action also affect basal and forskolin-stimulated cAMP accumulation. Changing medium prominently increases extracellular levels of ATP in Madin-Darby canine kidney, COS-7, and HEK-293 cells. Mechanical stimulation of ATP release likely occurs in virtually every experimental protocol with cultured cells, implicating such release and …

Effect Of Actinomycin D And Cycloheximide On Ischemic Preconditioning-Induced Delayed Cardioprotective Effect In Rats, Devinder Singh, Ajay Sharma, Manjeet Singh

Pharmacy Faculty Articles and Research

The present study was designed to investigate the effect of actinomycin D, a transcription inhibitor, and cycloheximide, a translation inhibitor, on the delayed cardioprotective effect of ischemic preconditioning. Left thoracotomy was performed in anaesthetized rats at 4th/5th intercostal space and polypropylene suture (5-0) was employed to occlude left common coronary artery. Ischemic preconditioning was produced by four episodes of 5 min of coronary artery occlusion followed by 5 min of reperfusion and thoracic cavity was sutured. Left thoracotomy was performed again after 24 hr of ischemic preconditioning and left coronary artery was occluded for 30 min followed by reperfusion for …

Novel Approaches For Designing 5'-O-Ester Prodrugs Of 3'-Azido-2'3'-Dideoxythymidine (Azt), Keykavous Parang, Leonard I. Wiebe, Edward E. Knaus

Pharmacy Faculty Articles and Research

3'-Azido-2'3'-dideoxythymidine (AZT, 1, zidovudine, RetrovirTM) is used to treat patients with human immunodeficiency virus (HIV) infection. AZT, after conversion to AZT-5'-triphosphate (AZT-TP) by cellular enzymes, inhibits HIV-reverse transcriptase (HIV-RT). The major clinical limitations of AZT are due to clinical toxicities that include bone marrow suppression, hepatic abnormalities and myopathy, absolute dependence on host cell kinase-mediated activation which leads to low activity, limited brain uptake, a sort half-life of about one hour in plasma that dictates frequent administration to maintain therapeutic drug levels, low potential for metabolic activation and/or high susceptibility to catabolism, and the rapid development of resistance by HIV-1. …

The Supreme Court Of Canada's Tax Jurisprudence: What's Wrong With The Rule Of Law, Lisa Philipps

Articles & Book Chapters

This paper reviews the history of the Supreme Court's tax jurisprudence focussing on the Court's ongoing struggle to define its proper institutional role in the creation and interpretation of the tax laws. An emprical overview is first presented to document the changing nature and volume of the Court's taxation caseload through history, and this is related to the evolution of Canada's fiscal system. Selected judgments from differing periods are then examined to illuminate how the Court has conceived its role in the adjudication of tax issues. The author suggests that tax decisions have been strongly informed by a classical liberal …

Adjudicating Constitutional Priorities In A Transnational Context: A Comment On Soobramoney’S Legacy And Grootboom’S Promise, Craig Scott, Philip Alston

Articles & Book Chapters

This article discusses the first two social rights cases to go to the Constitutional Court under the 1996 Constitution. Soobramoney v Minister of Health, KwaZulu-Natal 1998 (I) SA 765 (CC) involved a claim ofa breach of the right to health care brought by one person pursuant to s 27 of the Bill of Rights. Grootboom v Oostenburg Municipality 2000 (3) BCLR 277 (C) involves a claim of breaches of rights to housing or shelter brought by some 900 persons under ss 26 and 28. The article seeks to demonstrate why the Court's judgment in Soobramoney would be problematic if replicated …

Sovereignty On The Northern Plains: Indian, European, American And Canadian Claims, Kent Mcneil

Articles & Book Chapters

The Colonization of North America by Europeans raised fundamental issues about the status and rights of the original inhabitants of this continent. Were the Indian and Inuit peoples sovereign nations, with territorial rights equivalent to those of the European sovereigns in the so-called Old World? Did they have rights to the soil on a par with those of landowners in Britain, France, or Spain? If they were sovereign nations with territorial or land rights, what impact did European colonization have on them? Even today, these questions have not been completely resolved. In Canada, for example, as recently as 1997 the …

Mothers, Other Mothers, And Others, Shelley A. M. Gavigan

Articles & Book Chapters

My title derives its inspiration in part from the end-of-day watch sounded for my daughter by another child at her day-care centre when I arrived to pick her up:'. . . your mother's here-the other one.' As I think back to that moment more than half a decade ago, I remember with fondness the ease with which my daughter's little friends were able to assimilate that she didn't have a daddy, but rather two mommies-even the competitive little girl who said, 'Oh yeah, well I have about 10 mommies.'

Too, I recall a yet earlier conversation with one of my …

Distance Perception: A Comparison Of In-Class And Distance-Learning Psychology Of Perception Classes, Greg C. Elvers, Donald J. Polzella

Psychology Faculty Publications

Fifty students were randomly assigned to take a perception class either in a traditional lecture or in a distance-learning format in which the students attended class only to take tests. The results failed to suggest that the students in the distance-learning condition performed differently in the course than the lecture students. There were differences in what the distance-learning and the lecture students found useful and what they disliked about the course. These findings could be used to help design better distance-learning courses.

On The Seasonal Mixed Layer Simulated By A Basin-Scale Ocean Model And The Mellor-Yamada Turbulence Scheme, Tal Ezer

CCPO Publications

Seasonal changes and vertical mixing processes in the upper layers of the North Atlantic Ocean are simulated with a basin-scale sigma coordinate ocean model that uses the Mellor-Yamada turbulence closure scheme. The cause of insufficient surface mixing and a too shallow summertime thermocline, common problems of ocean models of this type, is investigated in detail by performing a series of sensitivity experiments with different surface forcing conditions and different turbulence parameterizations. A recent improvement in the parameterization of the dissipation term in the Mellor-Yamada turbulence scheme, which has shown a significant improvement in one-dimensional calculations, had a positive but relatively …

Limited By Law? Gender, Corporate Law And The Family Firm, Mary G. Condon

Articles & Book Chapters

The business enterprise is central to the operation of the Canadian capitalist economy in that it is a vehicle for the accumulation of profit, as well as a significant social location of employment. It is therefore one of the key mechanisms through which inter-class relations are mediated. A number of feminist scholars have pointed out that those class relations cannot be understood in isolation from gender relations. As Folbre and Hartmann (1988: 192) note disparagingly, 'the rhetoric of class interest simply subsumes the possibility of gender interests .' In their historical study of the English middle class between 1780 and …
