Geographic, Seasonal, And Precipitation Chemistry Influence On The Abundance And Activity Of Biological Ice Nucleators In Rain And Snow, Brent C. Christner, Rongman Cai, Cindy E. Morris, Kevin S. Mccarter, Christine M. Foreman, Mark L. Skidmore, Scott N. Montross, David C. Sands

Faculty Publications

Biological ice nucleators (IN) function as catalysts for freezing at relatively warm temperatures (warmer than -10°C). We examined the concentration (per volume of liquid) and nature of IN in precipitation collected from Montana and Louisiana, the Alps and Pyrenees (France), Ross Island (Antarctica), and Yukon (Canada). The temperature of detectable ice-nucleating activity for more than half of the samples was ≥ -5°C based on immersion freezing testing. Digestion of the samples with lysozyme (i.e., to hydrolyze bacterial cell walls) led to reductions in the frequency of freezing (0-100%); heat treatment greatly reduced (95% average) or completely eliminated ice nucleation at …

A Reassessment Of James Joyce's Female Characters, Anna Margaretha Gordon

Theses and Dissertations

The female characters in James Joyce's fiction have received considerable critical attention since the publication of his writings and are often denigrated as misogynist portrayals of women. However, a textual and historical analysis of the female characters in A Portrait of the Artist as a Young Man, Dubliners, Ulysses, and Finnegans Wake shows them in a more constructive light. Such an analysis reveals them to be sympathetic portrayals of the situation of Irish women at the turn of the twentieth century. An historical contextualization of the characters is essential in any reading of Joyce, but is particularly important for his …

The Nature And Dynamics Of Internet Pornography Exposure For Youth., Chiara Sabina, Janis Wolak, David Finkelhor

Sociology

Abstract

We examined exposure to Internet pornography before the age of 18, as reported by college students (n = 563), via an online survey. Ninety-three percent of boys and 62% of girls were exposed to online pornography during adolescence. Exposure prior to age 13 was relatively uncommon. Boys were more likely to be exposed at an earlier age, to see more images, to see more extreme images (e.g., rape, child pornography), and to view pornography more often, while girls reported more involuntary exposure. If participants in this study are typical of young people, exposure to pornography on the Internet can …

Ethnobotany And Traditional Management Of Drought Tolerant Tree Species In Homestead Forests Of Bangladesh, Mahbubul Alam, Yasushi Furukawa

Ethnobotanical Leaflets

A study has been conducted in the homesteads of drought-prone northwestern region of Bangladesh. Since there is no natural forest, the overall climatic condition is very harsh and progressive trend of desertification is threatening the livelihood of poor people. So it is important to carry out extensive plantations throughout the region to reverse the current trend of drought and desertification. The study identified a list of 19 drought tolerant species suitable for planting in the homesteads as well as in the vacant spaces. The rural people are heavily dependent on those species for their daily requirement of timber, fruits, fuel, …

Anti-Hyperglycaemic And Insulin Release Effects Of Coccinia Grandis (L.) Voigt Leaves In Normal And Alloxan Diabetic Rats, Asirvatham Doss, Rangasamy Dhanabalan

Ethnobotanical Leaflets

Coccinia grandis (L.) Voigt (Cucurbitaceae), occurs throughout the world and has intensive popular use in the treatment of infections. The main aim of the present work was to investigate the antidiabetic effects of aqueous extracts of leaves of C. grandis obtained by Decoction method. Graded doses of the aqueous extract were administered to normal and experimental diabetic rats for 10 days. Significant (p < 0.05) reduction in fasting blood glucose levels were observed in the normal as well as in the treated diabetic animals. Serum insulin levels were not stimulated in the animals treated with the extract. The changes in body weight, serum lipid profiles, liver glycogen levels were assessed in the extract treated diabetic rats and compared with diabetic control and normal animals.

Revitalization Of Siddha Medicine In Tamilnadu, India - Changing Trends In Consumer’S Attitude: A Survey, A. Krishnan Et Al.

Ethnobotanical Leaflets

Socioeconomic characteristics have significant impact on consumer’s attitude towards the usage of traditional system of medicine. Though traditional systems of medicine have made significant contributions towards fulfilling healthcare needs of the people in the past, impacts of modern medicine have been so large that traditional medicine witnessed a dark period in southern part of India. While such practices are common in the rural/ remote areas, of late, change in the trend with respect to the usage of Siddha medicine as complementary alternative therapy among urban population has been observed. Present study aims to evaluate the resurgence of interest in Siddha …

Abcb6 Is A Porphyrin Transporter With A Novel Trafficking Signal That Is Conserved In Other Abc Transporters, Yu Fukuda

Theses and Dissertations (ETD)

The ATP-binding cassette (ABC) transporters play an important role as a barrier to protect cells from the accumulation of toxic xenobiotics and metabolites due to their ability to translocate a wide array of compounds across lipid bilayers. However, many ABC transporters, especially the ones localized in the intracellular organelles, are involved in critical biological processes such as antigen presentation. The core unit of ABC transporters contains two functional domains: the membrane spanning domain (MSD) and the nucleotide binding domain. The full transporters contain two of these units in tandem in a single polypeptide, whereas the half transporters only contain one …

Detection Of An So2 Plume Over Sapporo, Japan From The Eruption Of Mt. Kasatochi Using A Balloon Sounding Technique, Gary A. Morris, Jun Hirokawa, Masatomo Fujiwara, Fumio Hasebe, Keisuke Ishida, Nicholay Krotkov, Mark R. Schoeberl, Walter Komhyr, Barry Lefer, James Flynn

Physics and Astronomy Faculty Presentations

During the month of August 2008, 10 ozonesondes were launched from Hokkaido University in Sapporo, Japan as part of a study to examine regional pollution during the Olympic period. Seven of these soundings included a second instrument with a filter designed to remove SO2 from the intake air stream. SO2 interferes with the normal chemistry of the electrochemical cell (ECC) method for ozone detection, with the net result being that each molecule of SO2 registers as minus one molecule of O3. Thus the unfiltered sonde reports [O3] - [SO2] while the filtered sonde reports [O3]. Laboratory tests prior to launch …

Imaging Activity Of Neuronal Populations With New Long-Wavelength Voltage-Sensitive Dyes, Joseph P. Wuskell, Leslie M. Loew

UCHC Articles - Research

We have assessed the utility of five new long-wavelength fluorescent voltage-sensitive dyes (VSD) for imaging the activity of populations of neurons in mouse brain slices. Although all the five were capable of detecting activity resulting from activation of the Schaffer collateral-CA1 pyramidal cell synapse, they differed significantly in their properties, most notably in the signal-to-noise ratio of the changes in dye fluorescence associated with neuronal activity. Two of these dyes, Di-2-ANBDQPQ and Di-1-APEFEQPQ, should prove particularly useful for imaging activity in brain tissue and for combining VSD imaging with the control of neuronal activity via light-activated proteins such as channelrhodopsin-2 …

Pareto Versus Welfare, Robert C. Hockett

Cornell Law Faculty Publications

Many normatively oriented economists, legal academics and other policy analysts appear to be "welfarist" and Paretian to at least moderate degree: They deem positive responsiveness to individual preferences, and satisfaction of one or more of the familiar Pareto criteria, to be reasonably undemanding and desirable attributes of any social welfare function (SWF) employed to formulate social evaluations. Some theorists and analysts go further than moderate welfarism or Paretianism, however: They argue that "the Pareto principle" requires the SWF be responsive to individual preferences alone - a position I label "strict" welfarism - and conclude that all social evaluation should in …

Abstraction As A Basis For The Computational Interpretation Of Creative Cross-Modal Metaphor, Sylvia Weber Russell

Computer Science

Various approaches to computational metaphor interpretation are based on pre-existing similarities between source and target domains and/or are based on metaphors already observed to be prevalent in the language. This paper addresses similarity-creating cross-modal metaphoric expressions. It is shown how the “abstract concept as object” (or reification) metaphor plays a central role in a large class of metaphoric extensions. The described approach depends on the imposition of abstract ontological components, which represent source concepts, onto target concepts. The challenge of such a system is to represent both denotative and connotative components which are extensible, together with a framework of general …

Anti-Venom Activity Of Medicinal Plants – A Mini Review, S. Meenatchisundaram Et Al.

Extracts from plants have been used among traditional healers, especially in tropical areas where there are plentiful sources, as therapy for snakebite for a long time. Several medicinal plants, which appear in old drug recipes or which have been passed on by oral tradition, are believed to be snakebite antidotes. In modern science, there have been many attempts to study these plants to clarify their effectiveness.

Preliminary Phytochemical Studies And Antibacterial Activity Of Ocimum Sanctum L., X. Baskaran

Ethnobotanical Leaflets

Ocimum sanctum, commonly known as ‘Sacred basil’ or ‘Holy basil’, is grown as a household plant in India. This preliminary phytochemical study was carried out in acetone, benzene and chloroform extracts and the results showed the presence of numerous phytochemical compounds. The antibacterial activity was analyzed using four different bacterial strains (E.coli, Bacillus subtilis, Staphylococcus aureus and Klebsiella pneumonia) by using agar disc diffusion method. Our bacterial assay revealed that the extracts showed good antibacterial activity, but the acetone extract didn’t show any specific activity. The presence of the phytochemicals signifies the potential of Ocimum sanctum as …
