Mcnally's Men: The Homosocial Gaze In Lips Together, Teeth Apart, Gary L. Green

Graduate Research Papers

I will examine McNally's 1991 play "Lips Together, Teeth Apart" and explore his theatrical representations of the male body onstage, primarily from the point of view of the heterosexual male characters, John and Sam, and their homosocial relationship with each other, and how they relate to the invisible presence of the gay men around them. While "Love! Valour! Compassion!" displays frontal nudity, "Lips Together, Teeth Apart" uses what I will call "narrative nudity," verbally conjuring up the physicality of the male body through images designed by McNally's vivid and colorful language and dialogue. This paper will be in two parts: …

The Portrayal Of Stepfamilies In Young Adult Literature, Cynthia Buck Tuttle

Graduate Research Papers

This study used content analysis of a selected sample of 25 contemporary young adult fiction books published between 1990-2000, to determine if stepfamilies are portrayed accurately. Contemporary American families are less likely to endure as a traditional biological household. Novels read by young adults may not reflect these new realities. Findings indicate that in a majority of the titles stepparents are portrayed positively and they gave their stepchild time and flexibility to adapt to the stepfamily situation. Findings also revealed that the biological relationship was not more important than the marital relationship. There was insufficient data to prove that the …

Effects Of Isochronal Exogenously Applied Synthetic-Ga_3, Fungal-Gibberellic Acid And Red Light On The Sheath Length Of The Second Leaf Of Oryza Sativa L.Cv. Tan-Ginbozu, Ş. Fati̇h Topçuoğlu, Serpi̇l Ünyayar

Turkish Journal of Biology

The effects of isochronal exogenously applied synthetic-GA_3, fungal-gibberellic acid and different light on the sheath length of the second leaf of Oryza sativa L.cv.Tan-ginbozu were determined under controlled environmental conditions. Our results showed that the effect of fungal-gibberellic acid on the sheath length of the second leaf is higher than that on the control groups (group of 1/2N Hoagland culture solution and group of 1/2N Hoagland culture solution+methanol); however, synthetic-GA_3 was more effective on the length of the second leaf than fungal gibberellic acid. Moreover, it was identified that the effect of red light is higher than that of fluorescent …

Dechlorination Of Bleached Kraft Pulp By Laccase Enzyme Produced From Some White-Rot Fungi, Nazi̇f Kolankaya, Arzu Taşpinar Ünal

Turkish Journal of Biology

The possibility of using crude laccase in the dechlorination of chlorine-based bleached kraft pulp was investigated. Culture supernatants of seven white-rot fungal strains and kraft-pulp samples taken from E1 (Alkaline Extraction-1), E2 (Alkaline Extraction-2) and D2 (Chlorinedioxide treatment) stages of chlorine-based bleaching processes were used as the laccase source and substrates respectively during the studies. The dechlorination activity of Trametes versicolor was found to be more than that of the other fungi examined. The addition of a laccase inducer, xylidine, into the culture medium of T. Versicolor led to an increase in dechlorination activity. In the experiment performed to find …

Blood-Serum Proteins Of Rattus Rattus And Rattus Norvegicus (Mammalia: Rodentia) In Turkey, Nuri̇ Yi̇ği̇t, Reyhan Çolak, Ercüment Çolak, Mustafa Sözen, Şaki̇r Özkurt

Turkish Journal of Biology

The blood serum proteins of 35 live specimens of Rattus rattus and Rattus norvegicus collected from ten localities in Turkey were examined by SDS-PAGE (sodium dodecyl sulphate - polyacrylamide gel electrophoresis). Globulin, albumin, postalbumin, and prealbumin proteins in blood serum showed different electrophoretic patterns in populations of R. rattusand R. norvegicus.Because of the variations in electrophoretic patterns of both species, these patterns do not seem to be diagnostic characters in distinguishing R. rattus from R. norvegicus.

Isolation And Characterization Of Pediocin Producing Pediococcus Pentosaceus Pep1 From Vacuum-Packed Sausages, Özlem Osmanağaoğlu, Yavuz Beyatli, Ufuk Gündüz

Turkish Journal of Biology

Pediococcus pentosaceus Pep1 was isolated from vacuum-packed sausages, and it was shown to produce a potentially novel antimicrobial agent active against several species of Lactobacillus, Lactococcus, Leuconostoc, Pediococcus, Staphylococcus, Enterococcus, Bacillus and Listeria, many of which are associated with food spoilage and health hazards of food origin. Gram-negative organisms such as Yersinia enterocolitica and Escherichia coli were not inhibited by this antimicrobial agent. Since the antimicrobial agent was found to be sensitive to proteolytic enzymes, resistant to heat and organic solvents and active over a wide range of pH values, between 3 and 8, apparently most stable in the lower …

Optimization Of Pcr Amplification Of Wheat Simple Sequence Repeat Dna Markers, Nurdan Doğrar, Mahi̇nur S. Akkaya

Turkish Journal of Biology

Simple Sequence Repeat (SSR) DNA markers or Microsatellites are di-, tri-, tetra-nucleotide tandem repeats containing loci of eukaryotic genomes. It is demonstrated that these loci are very polymorphic due to the change in the number of repeating units among the individuals of populations. Each SSR locus can easily be amplified by using a polymerase chain reaction (PCR) knowing the DNA sequence flanking the repeat region specifically. The only limiting feature of the application of these markers is the need for prior sequence information for developing primers in locus-specific PCR amplification. This limitation is alleviated for the economically important species and …

Substitution Of The Conserved Cysteine With Glycine (Cys82gly) Of Agmenellum Quadruplicatum Methylase Aqul (M. Aqul) Is Not Cytotoxic To E. Coli, Hati̇ce Pinarbaşi, Ergün Pinarbaşi, David P. Hornby

Turkish Journal of Biology

Cytosine 5 DNA methyltransferases share ten conserved motifs. Motif IV contains an absolutely conserved proline-cysteine dipeptide. The cysteine residue of this motif is involved in catalysis by forming a covalent bond with the 6-position of cytosine prior to methyl group transfer. AquI DNA methyltransferase recognising the sequence CCCGGG is a heterodimer unlike other C5 DNA methyltransferases. We changed the conserved cysteine (Cys82) of M.AquI to serine and glycine. The presence of mutations was confirmed by automated DNA sequencing. Mutants were tested by in vivo plasmid protection assay and also by transformation into mcrA+BC+ strain of E. coli. Replacement of the …

Random Amplified Polymorphic Dna (Rapd) Markers, Fevzi̇ Bardakci

Turkish Journal of Biology

Due to advances in molecular biology techniques, large numbers of highly informative DNA markers have been developed for the identification of genetic polymorphism. In the last decade, the random amplified polymorphic DNA (RAPD) technique based on the polymerase chain reaction (PCR) has been one of the most commonly used molecular techniques to develop DNA markers. RAPD markers are amplification products of anonymous DNA sequences using single, short and arbitrary oligonucleotide primers, and thus do not require prior knowledge of a DNA sequence. Low expense, efficiency in developinga large number of DNA markers in a short time and requirement for less …

Determination Of The Dna And Amino Acid Sequences Of The Lactate Dehydrogenase Gene From Plasmodium Falciparum Strains K1 And Pf Fcbr: A Route To The Design Of New Antimalarials, Di̇lek Turgut Balik, J. John Holbrook

Turkish Journal of Biology

This paper describes cloning of the gene coding for the lactate dehydrogenase (LDH) gene from the two different strains of Plasmodium falciparum, K1 and PF FCBR. The DNA sequences of LDH genes of these two strains were found to be identical. Amino acid sequence alignment of LDH from P. falciparum strains K1 and PF FCBR (PfLDH) to some other known LDH sequences showed that PfLDH has 29% residue identities with Bacillus stearothermophilus (BsLDH) and 29%, 31%, 33% with dogfish, man-M_4, and pig-M_4 LDHs, respectively. It was also shown that PfLDH has insertions and single amino acid deletions. Two deletions are …

The Analysis Of Rhodococcus Ruber In Different Growth Conditions Using Pyrolysis Mass Spectrometry (Pyms), Ergi̇n Kari̇ptaş, Kami̇l Işik, Nevzat Şahi̇n, Reşi̇t Özkanca, Alan C. Ward

Turkish Journal of Biology

Batch grown cultures of Rhodococcus ruber from different growth phases and continuous grown cultures from carbon, phosphate and magnesium limitation were analysed by pyrolyis mass spectrometry (PyMS). Batch grown cells showed significantly different pyrograms and the stationary phase cells could be clearly distinguished from exponential phase cells. Mass pyrograms of carbon, phosphate and magnesium limited cells were clearly different and, for carbon and phosphate limitation, clear trends were seen with different dilution rates. Changes in pH and temperature had no systematic effect on mass pyrograms.

Oxylipin Pathway In The Biosynthesis Of Fresh Tomato Volatiles, Emi̇n Yilmaz

Turkish Journal of Biology

Fresh tomato volatiles are formed in intact fruit during ripening and upon tissue disruption. There are different pathways involved in the biosynthesis of these volatiles. The oxylipin pathway uses free unsaturated fatty acids with the sequential action of lipoxygenase, hydroperoxide lyase and alcohol dehydrogenase to produce volatile aldehyde and alcohol compounds. Oxylipin volatiles are the most important components in fresh tomato aroma. In order to genetically improve the quality of tomato aroma, the biochemistry of aroma synthesis must be studied thoroughly. This review examines current knowledge of the subject and opens new areas for further investigation.

Production Of Single-Cell Protein From Ram Horn Hydrolysate, Esabi̇ Başaran Kurbanoğlu

Turkish Journal of Biology

Candida utilis NRRL Y-900 was grown on horn hydrolysate for single-cell protein production. First, ram horns obtained from slaughterhouse in Erzurum were hydrolyzed by physical and chemical methods and crude horn hydrolysate (CHH) was obtained. The contents of protein, nitrogen, ash, some minerals, total sugars and amino acids of CHH were determined and it was seen that it has sufficient organic and inorganic materials to allow its use as a substrate source in the production of single-cell protein. The CHH was enriched by addition of yeast extract, glucose and KH_2PO_4. The effects of different CHH concentrations (1, 2, 3, 4, …

In Situ Localization Of Germin Gene Expression During Auxin Induced Callus Formation, Mahmut Çalişkan

Turkish Journal of Biology

Wheat embryogenic callus was induced by treating immature wheat embryos with 2,4-D. Digoxigenin-labeled germin sense and anti-sense RNA probes were prepared by in vitro transcription. By using these probes it was revealed that there was a striking induction of germin gene expression prior to visible callus formation. Although no germin gene expression was localized on the sections of immature embryos which were not incubated in callus induction medium, following 4 hours incubation in callus induction medium, germin mRNA was localized on the sections of immature embryos. Germin gene expression more conspicuous and widespread on the sections which were incubated for …

Viral Control Of The European Pine Sawfly, Neodiprion Sertifer (Geoffroy) In Turkey, Mustafa Yaman, Remzi̇ye Nalçacioğlu, Zi̇hni̇ Demi̇rbağ

Turkish Journal of Biology

The European pine sawfly, Neodiprion sertifer (Geoffr.) (Hymenoptera: Diprionidae), is a serious pest of pine plantations and ornamentals. Chemical pesticides used to control this pest have a detrimental effect on the environment. The Neodiprion sertifer nuclear polyhedrosis virus (NsNPV) frequently causes considerable decreases in the populations but doses not harm other animals or plants. In this study, we tested five different concentrations of NsNPV against the larvae of N. sertifer and showed viral infection using Giemsa staining. When a viral concentration of 5x10^9 PIB/ml (Polyhedral Inclusion Body) was utilized, larval mortality started on the fourth day and reached 90.4% on …

Susceptibility Of Different Bean (Phaseolus Vulgaris L.) Cultivars To Agrobacterium Tumefaciens, Azi̇z Karakaya, Sebahatti̇n Özcan

Turkish Journal of Biology

Although several direct gene transfer techniques have been developed, Agrobacterium tumefaciens is still preferred for the transfer of foreign genes into many plant species. Perhaps the greatest weakness of A. tumefaciens is the host range limitation. Therefore, in this study, the susceptibility of different bean cultivars to oncogenic A. tumefaciens strain A281 was assessed. The cultivars 4F-2409, Karacaşehir-90, Akman-98 and Eskişehir-855 resulted in higher frequencies of tumor formation than the other cultivars tested. Tumor formation was not observed in Afyon-3, IVD-10, Göynük-98, Yunus-90 or Şehirali-90 bean cultivars. Tumor formation was observed on both the hypocotyl and epicotyl portions of the …

Near The Lewis & Clark Trail, Chad Colin Husted

LSU Master's Theses

Near the Lewis & Clark Trail is a creative writing thesis that contains two distinct parts. Part one is a short story cycle: a collection of interlinked narratives that together, tell a larger, cohesive story. Many different points of view, narrative techniques, and non-linear time sequences are used in order to provide a pastiche of different voices, points in time, and perspectives, that ultimately form an overall narrative structure. In addition to the stories, there are several fictional documents that are used to separate the work at critical times, and to provide subtext. In between the stories are: a letter …

The Problem Of A Viscoelastic Cylinder Rolling On A Rigid Half-Space, John Murrough Golden, G.A.C. Graham

Articles

The problem of a viscoelastic cylinder rolling on a rigid base, propelled by a line force acting at its centre, is solved in the noninertial approximation. The method used is based on a decomposition of hereditary integrals developed by the authors in previous work, and on the viscoelastic Kolosov-Muskhelishvili equations which are used to generate a Hilbert problem. In this formulation, the problem reduces to a nonsingular integral equation in space and time, which simplifies under steady-state conditions and for exponential decay materials, to algebraic form. There are also two subsidiary conditions.

In the case of a standard linear model, …
