Teaching Bernoulli's Principle through Demonstrations

ABSTRACT

One proven strategy to help students make sense of abstract concepts is to sequence instruction so students have exploratory opportunities to investigate science before being introduced to new science explanations (Abraham and Renner 1986 Abraham, M. R. and Renner, J. W. 1986. The sequence of learning cycle activities in high school chemistry. Journal of Research in Science Teaching, 23: 121–143. [Crossref], [Web of Science ®] , [Google Scholar]; Renner, Abraham, and Birnie 1988 Renner, J. W., Abraham, M. R. and Birnie, H. H. 1988. The necessity of each phase of the learning cycle in teaching high school physics. Journal of Research in Science Teaching, 25: 39–58. [Crossref], [Web of Science ®] , [Google Scholar]). To help physical science teachers make sense of how to effectively sequence lessons, this article summarizes our experiences using an exploration–explanation sequence of instruction to teach Bernoulli's principle to prospective middle and secondary science teachers in a science methods course. We use demonstrations during our Bernoulli unit to help students go back and forth between their observations of phenomenon and what occurs on the microscopic level with what we have termed molecular talk. Students engage in guiding questions, consider their old and new understandings of science, and use evidence to construct new ideas during all stages of the lesson.

A new clionaid sponge infests live corals on the west coast of India (Porifera,Demospongiae, Clionaida)

Coral reef ecosystems depend on the balanced interplay of constructive and destructive processes and are increasingly threatened by environmental change. In this context bioeroding sponges play a significant role in carbonate cycling and sediment production. They occasionally aggravate erosional processes on disturbed reefs. Like other coral ecosystems, Indian reefs have suffered from local and global effects. However, the systematic affiliation and diversity of many Indian bioeroding sponges and their infestation rates are largely confused or unknown. The present study describes a new bioeroding sponge species, Cliona thomasi sp. nov. from the central west coast of India. It belongs to the Cliona viridis species complex, displaying the key characters of tylostyles and spirasters, as well as harbouring photosymbiotic dinoflagellates. Specific morphological characteristics and molecular data from nrITS1 DNA and 28S rDNA distinguished C. thomasi sp. nov. from other known C. viridis complex and a number of Spheciospongia species. The historic sample of ‘Suberites coronarius’ from Mergui Archipelago (sensu Carter, 1887 Carter, H. J. (1887). Report on the marine sponges, chiefly from King Island, in the Mergui Archipelago, collected for the trustees of the Indian museum, Calcutta, by Dr. John Anderson, F. R. S., superintendent of the museum. Zoological Journal of the Linnean Society, 21, 61–84. https://doi.org/10.1111/j.1096-3642.1887.tb00381.x[Crossref] , [Google Scholar]), but not from the Caribbean (sensu Carter, 1882 Carter, H. J. (1882). Some sponges from the West Indies and Acapulco, in the Liverpool Free Museum, described with general and classificatory remarks. Annals and Magazine of Natural History, 9, 266–301, 346–368, pls. XI-XII. https://doi.org/10.1080/00222938209459039[Taylor &; Francis Online] , [Google Scholar]), is conspecific with C. thomasi sp. nov. Cliona thomasi sp. nov. is locally very abundant, appears to be a key bioeroder, and thus regular monitoring of its abundance, distribution and infestation patterns is recommended.     

Evaluation of Bovine High-Density SNP Genotyping Array in Indigenous Dairy Cattle Breeds

In total 52 samples of Sahiwal (19 Excoffier L, Laval G, Schneider S. Arlequin 3.01: An integrated software package for population genetics data analysis. Evol Bioinform Online 2005; 1:47–50.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]), Tharparkar (17 Hayes BJ, Bowman PJ, Chamberlain, AJ, Goddard ME. Invited review: genomic selection in dairy cattle: progress and challenges.

Identification of genomic differences between Hanwoo and Holstein breeds using the Illumina Bovine SNP50 BeadChip. Genomics Inform 2011; 9:69–73.[Crossref] , [Google Scholar]) were genotyped by using BovineHD SNP chip to analyze minor allele frequency (MAF), genetic diversity, and linkage disequilibrium among these cattle. The common SNPs of BovineHD and 54K SNP Chips were also extracted and evaluated for their performance. Only 40%?50% SNPs of these arrays was found informative for genetic analysis in these cattle breeds. The overall mean of MAF for SNPs of BovineHD SNPChip was 0.248?±?0.006, 0.241?±?0.007, and 0.242?±?0.009 in Sahiwal, Tharparkar and Gir, respectively, while that for 54K SNPs was on lower side. The average Reynold’s genetic distance between breeds ranged from 0.042 to 0.055 based on BovineHD Beadchip, and from 0.052 to 0.084 based on 54K SNP Chip. The estimates of genetic diversity based on HD and 54K chips were almost same and, hence, low density chip seems to be good enough to decipher genetic diversity of these cattle breeds. The linkage disequilibrium started decaying (r²?相似文献   

Animal-Facilitated Therapy Revisited

In Disney/Pixar's phenomenally popular animated film Finding Nemo (Stanton, 2003 Stanton, A. Writer/Director. 2003. Finding Nemo [Motion picture], United States: Pixar Animation Studios.  [Google Scholar]), one of the central themes of fish welfare was highlighted when the moorish idol, Gill, commented, “Fish aren't meant to be kept in a box, kid. It does things to you.” The notion that fish might have the capacity to suffer in captivity (Chandroo, Duncan, & Moccia, 2004a Chandroo, K. P., Duncan, I. J. H and Moccia, R. D. 2004a. Can fish suffer?: Perspectives on sentience, pain, fear and stress. Applied Animal Behaviour Science, 86: 225–250. [Crossref], [Web of Science ®] , [Google Scholar], 2004b Chandroo, K. P., Duncan, I. J. H and Moccia, R. D. 2004b. An evaluation of current perspectives on consciousness and pain in fish. Fish and Fisheries, 5: 281–295. [Crossref], [Web of Science ®] , [Google Scholar]) links to the larger question of sentiency, which remains a fundamental tenet when justifying concerns for nonhuman animal welfare (Dawkins, 2006 Dawkins, M. S. 2006. Through animal eyes: What behaviour tells us. Applied Animal Behaviour Science, 100: 4–10. [Crossref], [Web of Science ®] , [Google Scholar]; Huntingford et al., 2006 Huntingford, F.

[Crossref], [Web of Science ®] , [Google Scholar]). Although terrestrial nonhuman-animal welfare has been discussed and explored for many years, the development of aquatic animal welfare concepts and approaches remains relatively new and beyond public awareness (Braastad, Damsgård, & Juell, 2006; Broom, 2007 Broom, D.

An Efficient Alternative Route To 3,6-Disubstituted-Furo[2,3-d]Pyrimidin-2-One Analogues

Copper(I)-catalyzed 5-endo-dig cyclizations of 5-(alkyn-1-yl)uracil derivatives had given poor yields of substituted furo[2 Robins, M. J. and Barr, P. J. 1983. Nucleic acid related compounds. 39. Efficient conversion of 5-iodo to 5-alkynyl and derived 5-substituted uracil bases and nucleosides. J. Org. Chem, 48: 1854–1862.

This limited flexibility for the synthesis of analogues with varied substituents at N3 and/or C6 of the furo[2 Robins, M. J. and Barr, P. J. 1983. Nucleic acid related compounds. 39. Efficient conversion of 5-iodo to 5-alkynyl and derived 5-substituted uracil bases and nucleosides. J. Org. Chem, 48: 1854–1862.

[PUBMED][INFOTRIEVE][CSA][CROSSREF][Crossref], [PubMed], [Web of Science ®] , [Google Scholar]]pyrimidin-2-one core has been overcome with 5-(3-hydroxyalkyn-1-yl)uracil compounds with no substituent at N1. Manipulation of the side-chain hydroxyl group gives access to additional furo[2,3-d]pyrimidin-2-one analogues.     

Attitudes to biotechnology: Estimating the opinions of a better-informed public

Public familiarity with basic scientific concepts and principles has been proposed as essential for effective democratic decision-making (Miller, 1998 Miller, J. D. 1998. The measurement of civic scientific literacy. Public Understanding of Science, 7: 203–23. [Crossref], [Web of Science ®] , [Google Scholar]). Empirical research, however, finds that public ‘scientific literacy’ is generally low, falling well short of what normative criteria would consider ‘acceptable’. This has prompted calls to better engage, educate and inform the public on scientific matters, with the additional, usually implicit assumption that a knowledgeable citizenry should express more supportive and favourable attitudes toward science. Research investigating the notion that ‘to know science is to love it’ has provided only weak empirical support and has itself been criticised for representing science and technology as a unified and homogenous entity. In practice, it is argued, how knowledge impacts on the favourability of attitudes will depend on a multiplicity of factors, not least of which is the particular area of science in question and the technologies to which it gives rise (Evans & Durant, 1992 Evans, G. and Durant, J. 1992. The relationship between knowledge and attitudes in the public understanding of science in Britain. Public Understanding of Science, 4: 57–74.  [Google Scholar]). This article uses a new method for examining the knowledge-attitude nexus on a prominent area of 21st century science—biotechnology. The idea that greater scientific knowledge can engender change in the favourability of attitudes toward specific areas of science is investigated using data from the 2000 British Social Attitudes Survey and the 1999 Wellcome Consultative Panel on Gene Therapy. Together the surveys measure public opinion on particular applications of genetic technologies, including gene therapy and the use of genetic data, as well as more general attitudes towards genetic research. We focus our analysis on how two different measures of knowledge impact on these attitudes; one a general measure of scientific knowledge, the other relating specifically to knowledge of modern genetic science. We investigate what impact these knowledge domains have on attitudes towards biotechnology using a regression-based modelling technique (Bartels, 1996 Bartels, L. M. 1996. Uninformed votes: information effects in presidential elections. American Journal of Political Science, 40(1): 194–230. [Crossref], [Web of Science ®] , [Google Scholar]; Althaus, 1998 Althaus, S. L. 1998. Information effects in collective preferences. The American Political Science Review, 92(3): 545–58. [Crossref], [Web of Science ®] , [Google Scholar]; Sturgis, 2003 Sturgis, P. 2003. Knowledge and collective preferences: a comparison of two approaches to estimating the opinions of a better-informed public. Sociological Methods and Research, 31(4): 453–85. [Crossref] , [Google Scholar]). Controlling for a range of socio-demographic characteristics, we provide estimates of what collective and individual opinion would look like if everyone were as knowledgeable as the currently best-informed members of the general public on the knowledge domains in question. Our findings demonstrate that scientific knowledge does appear to have an important role in determining individual and group attitudes to genetic science. However, we find no support for a simple ‘deficit model’ of public understanding, as the nature of the relationship itself depends on the application of biotechnology in question and the social location of the individual.     

Capillary Effects on Natural Remobilization of Pools of Dense Non-Aqueous Phase Liquid Mixtures in Porous Media

The natural remobilization of an initially static mixed dense non-aqueous phase liquid (DNAPL) pool due to dissolution was demonstrated by (Roy et al. 2002 Roy, J. W., Smith, J. E. and Gillham, R. W. 2002. Natural remobilization of multicomponent DNAPL pools due to dissolution. J. Contam. Hydrol., 59: 163–186. [Crossref], [PubMed], [Web of Science ®] [Google Scholar], 2004 Roy, J. W., Smith, J. E. and Gillham, R. W. 2004. Laboratory evidence of natural remobilization of multicomponent DNAPL pools due to dissolution. J. Contam. Hydrol., 74: 145–161. [Crossref], [PubMed], [Web of Science ®] [Google Scholar]) using a compositional mathematical model and laboratory experiments with open pools over a porous medium. The purposes of this study were to: a) demonstrate natural remobilization for a pool within porous media (as opposed to an open pool); and b) analyze the capillary effects associated with residual formation, a changing saturation profile, hysteresis, and aging, as these processes may reduce the potential for natural remobilization of pools in porous media. DNAPL pools comprised of tetrachloroethene and benzene were created within a zone of larger glass beads overlying smaller glass beads, in a water-saturated 2-D flow cell. In one case, remobilization occurred in the form of a DNAPL finger, after 56 days of flushing. In another case, no remobilization had occurred after 64 days of flushing, though the density increased by 430 kg m ^?3 and remobilization was predicted by the compositional model. Comparison of observations with model predictions suggest that contact angle hysteresis, related to an observed change in wettability, was the most significant contributing factor causing overprediction of the potential for natural remobilization.

Thermodynamics of Agricultural Sustainability: The Case of US Maize Agriculture

This paper considers the local, field-scale sustainability of a productive industrial maize agrosystem that has replaced a fertile grassland ecosystem.

Using the revised thermodynamic approach of Svirezhev (1998 Svirezhev, Y. M. 1998. “Thermodynamic orientors: How to use Thermodynamic concepts in ecology”. In Eco Targets, Goal Functions, and Orientors, 102–122. Berlin: Springer Verlag. [Crossref] [Google Scholar], 2000 Svirezhev, Y. M. 2000. Thermodynamics and ecology. Ecological Modelling, 132: 11–22. [Crossref], [Web of Science ®] [Google Scholar]) and Steinborn and Svirezhev (2000) Steinborn, W. and Svirezhev, Y. M. 2000. Entropy as an indicator of sustainability in agro-ecosystems: North Germany case study. Ecol. Mode., 133: 247–257. [Crossref], [Web of Science ®] [Google Scholar], it is shown that currently this agrosystem is unsustainable in the U.S., with or without tilling the soil. The calculated average erosion rates of soil necessary to dissipate the entropy produced by U.S. maize agriculture, 23–45 t ha^?1 yr^?1, are bounded from above by an experimental estimate of mean soil erosion by conventional agriculture worldwide, 47 t ha^?1 yr^?1, (Montgomery, 2007 Montgomery, D. R. 2007. Soil erosion and agricultural sustainability. PNAS, 104(33): 13268–13272. [Crossref], [PubMed], [Web of Science ®] [Google Scholar]). Between 1982 and 1997, US agriculture caused an estimated 7–23 t ha^?1 yr^?1 of average erosion with the mean of 15 t ha^?1 yr^?1 (USDA-NRCS Database). The lower mean erosion rate of no till agriculture, 1.5 t ha^?1 yr^?1 (Montgomery, 2007 Montgomery, D. R. 2007. Soil erosion and agricultural sustainability. PNAS, 104(33): 13268–13272. [Crossref], [PubMed], [Web of Science ®] [Google Scholar]), necessitates the elimination of weeds and pests with field chemicals—with the ensuing chemical and biological soil degradation, and chemical runoff—to dissipate the produced entropy. The increased use of field chemicals that replace tillers is equivalent to the killing or injuring of up to 300 kg ha^?1 yr^?1 of soil flora and fauna. Additional soil degradation, not calculated here, occurs by acidification, buildup of insoluble metal compounds, and buildup of toxic residues from field chemicals. The degree of unsustainability of an average U.S. maize field is high, requiring 6–13 times more energy to reverse soil erosion and degradation, etc., than the direct energy inputs to maize agriculture. This additional energy, if spent, would not increase maize yields. The calculated “critical yield” of “organic” maize agriculture that does not use field chemicals and fossil fuels is only 30 percent lower than the average maize yield of 8.7 tons per hectare (～140 bu/acre) assumed here. This critical yield would not likely be achieved and sustained by large monocultures, but might be achieved by more balanced organic polycultures (Baum et al., 2008 Baum, A. W., Patzek, T. W., Bender, M., Renich, S. and Jackson, W. 2008. The Visible, Sustainable Farm: A Comprehensive Energy Analysis of a Midwestern Farm 1–34.

Salmonella Typhimurium methionine sulfoxide reductase A (MsrA) prefers TrxA in repairing methionine sulfoxide

Intraphagocytic survival of Salmonella Typhimurium (ST) depends (at least in part) upon its ability to repair oxidant-damaged macromolecules. Met residues either free or in protein bound form are highly susceptible to phagocyte-generated oxidants. Oxidation of Mets leads to Met-SO formation, consequently loss of protein functions that results in cell death. Methionine sulfoxide reductase (Msr) reductively repairs Met-SO to Met in the presence of thioredoxin (trx) and thioredoxin reductase (trxR). Earlier we reported that methionine sulfoxide reductase A (msrA) gene deletion strain of ST suffered oxidative stress.^[1 Trivedi, R.N.; Agarwal, P.; Kumawat, M.; Pesingi, P.K.; Gupta, V.K.; Goswami, T.K.; Mahawar, M. Methionine Sulfoxide Reductase A (MsrA) Contributes to Salmonella Typhimurium Survival Against Oxidative Attack of Neutrophils. Immunobiology 2015, 220(12), 1322–1327.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]^] Thioredoxin system of ST comprises of two thioredoxins (trxA and trxC) and one thioredoxin reductase (trxB). Preferred trx utilized in MsrA-mediated repair of Met-SO is not known. In current study, we cloned, expressed, and purified ST TrxA, TrxB, TrxC, and MsrA in recombinant forms. The migration of TrxA, TrxB, TrxC, and MsrA proteins was approximately 10, 36, 16, and 26?kDa on SDS-gels. The nicotinamide adenine dinucleotide phosphate hydrogen (NADPH)-linked reductase assays interpreted that MsrA utilized two times more NADPH for the reduction of S-methyl p-tolyl sulfoxide when TrxA was included in the assays as compared to TrxC.

Buried Tracks: Ichnological Applications of High-Frequency Georadar

Recognition and sampling of traces in unconsolidated sands present a major challenge for ichnologists. This can be partially remedied through the application of high-resolution geophysical techniques, such as ground-penetrating radar (GPR or georadar), which uses electromagnetic impulse for continuous imaging of shallow subsurface. It addition to geological applications, GPR imaging has been used in several studies focused on animal traces as related to conservation of endangered fossorial species (Kinlaw et al., 2007 Kinlaw, A.
