Effect Of Superconsciousness External Energy On The Atomic, Crystalline And Powder Characterisitics Of “Carbon Allotrope Powders”, Mahendra Kumar Trivedi

Mahendra Kumar Trivedi

Scientists are searching for eluding link between spirituality and science. Some believe fundamental essences of universe to be energy and information. As per current understanding energy and matter always co- existed and is considered one and the same. Energy is consideredas ‘matter-inperpetual-motion’and matter as ‘stationary-energy’.Inter conversion between matter and energy has been defined by Einstein’s famous energy-mass equation (E=mc2) which has been provedby nuclear physicists using complex nuclear reactions involving high energy particles. However, many spiritual masters have claimed to realize this energy-matter inter conversion using their spiritual powers/energy but scientifically unknown and unverified. It is the first time that …

Genetic Effect Of The Dwarfing Genes On Some Culm Characteristics Associatcd With Lodging Resistance In Bread Wheat, Md. Mahbub Hasan

Md. Mahbub Hasan

Due to the challenge of screening traits related to lodging resistance under natural field conditions, selection for lodging resistant varieties in wheat breeding programs is difficult. The identification of easily measurable culm anatomical traits related to lodging resistance would simplify the selection process. The present study was conducted to determine the effect of dwarfing genes on culm anatomical traits related to lodging resistance in our of basal internode 1. Field and laboratory study was conducted in Shahjalal University of Science and Technology, Sylhet, Bangladesh with eight wheat genotypes having Rhr1, Rht2 dwarfing genes in them and a local land race …

Effects Of Different Denture Cleansers On The Tensile Bond Strength Of Denture Liners, Selda Keskin

The effect of two denture cleansers (Polident1 and Protefix1) on the tensile bond strength between four soft liner materials (Molloplast B1, Permaflex1, Sofreliner Tough Medium1, and GC Reline Soft1) and a conventional denture base resin was investigated. For each of the liner materials 35 test specimens were prepared according to test the requirements and assigned into seven groups (n¼5). Before tensile testing, five of the liner specimens were kept in water or soaked in two cleansing solutions during 2 and 7 d. Five other samples served as a control group subjected directly to tensile testing. The bond strength values were …

Tracking Insertion Mutants Within Libraries By Deep Sequencing And A Genome-Wide Screen For Haemophilus Genes Required In The Lung, Jeffrey D. Gawronski, Sandy M. S. Wong, Georgia Giannoukos, Doyle V. Ward, Brian J. Akerley

Brian J. Akerley

Rapid genome-wide identification of genes required for infection would expedite studies of bacterial pathogens. We developed genome-scale "negative selection" technology that combines high-density transposon mutagenesis and massively parallel sequencing of transposon/chromosome junctions in a mutant library to identify mutants lost from the library after exposure to a selective condition of interest. This approach was applied to comprehensively identify Haemophilus influenzae genes required to delay bacterial clearance in a murine pulmonary model. Mutations in 136 genes resulted in defects in vivo, and quantitative estimates of fitness generated by this technique were in agreement with independent validation experiments using individual mutant strains. …

The Role Of Temperature And Desiccation Stress In Limiting The Local-Scale Distribution Of The Owl Limpet, Lottia Gigantea, Luke P. Miller, Christopher D. G. Harley, Mark W. Denny

Luke P. Miller

1 Small-scale distributions of rocky intertidal organisms may be determined in part by temperature and desiccation stress during low tide and the ability of organisms to resist such stresses. Biophysical modelling techniques, coupled with data on the physiological tolerance of organisms can be used to predict the frequency and severity of abiotic stress events. 2 The limpet Lottia gigantea is a major competitor for primary space on rocky shores along the west coast of North America. The goal of this study was to quantify the thermal and desiccation tolerance of this species and to predict the frequency of stressful events …

On The Prediction Of Extreme Ecological Events, Mark W. Denny, Luke J. H. Hunt, Luke P. Miller, Christopher D. G. Harley

Luke P. Miller

Ecological studies often focus on average effects of environmental factors, but ecological dynamics may depend as much upon environmental extremes. Ecology would therefore benefit from the ability to predict the frequency and severity of extreme environmental events. Some extreme events (e.g., earthquakes) are simple events: either they happen or they don't, and they are generally difficult to predict. In contrast, extreme ecological events are often compound events, resulting from the chance coincidence of run-of-the-mill factors. Here we present an environmental bootstrap method for resampling short-term environmental data (rolling the environmental dice) to calculate an ensemble of hypothetical time series that …

Control Of Tribolium Castaneum (Herbst) (Coleoptera: Tenebrionidae) With Spinosad Dust Formulation In Different Oilseeds, Adel Khashaveh

Adel Khashaveh

The insecticidal effect of spinosad dust, a formulation that contains 0.125% spinosad, was evaluated against adults of Tribolium castaneum (Herbst) on 4 commodities: safflower, sunflower, sesame, and canola. Fifty grams of each commodities were treated with 3 doses of the formulation: 100, 200, and 300 ppm, (corresponding to 0.125, 0.25, and 0.375 mg kg–1 a.i., respectively) at 27 °C and 60 ± 5% relative humidity. The mortality of T. castaneum adults was measured after 1, 2, 7, 14, and 21 days of exposure. After the mortality count on day 21, all surviving insects were removed while the samples were kept …

Tree-Compatible Ground Covers For Reforestation And Erosion Control, James Burger, Victor Davis, Jennifer Franklin, Carl Zipper, Jeff Skousen, Chris Barton, Patrick Angel

Jennifer Franklin

Productive native forests create economic value for landowners, produce raw materials for wood-based products, and provide benefits such as watershed control, water quality protection, carbon storage, wildlife habitat, and native plant diversity. Owners of lands mined for coal in Appalachia are increasingly interested in assuring that productive forests are restored after mining.

Sediment control is essential to coal mine reclamation under the Surface Mining Control and Reclamation Act (SMCRA). Here, we describe how mining firms can achieve good tree survival and restore forest productivity by using tree-compatible ground covers, when necessary, to control erosion and meet ground cover standards.

Incorporating Fairness Motives Into The Impulse Balance Equilibrium And Quantal Response Equilibrium Concepts: An Application To 2x2 Games, Alessandro Tavoni

Alessandro Tavoni

Substantial evidence has accumulated in recent empirical works on the limited ability of the Nash equilibrium to rationalize observed behavior in many classes of games played by experimental subjects. This realization has led to several attempts aimed at finding tractable equilibrium concepts which perform better empirically; one such example is the impulse balance equilibrium (Selten, Chmura, 2008), which introduces a psychological reference point to which players compare the available payoff allocations. This paper is concerned with advancing two new, empirically sound, concepts: equity-driven impulse balance equilibrium (EIBE) and equity-driven quantal response equilibrium (EQRE): both introduce a distributive reference point to …

Influence Of Reproductive And Environmental Factors On Population Size .. Of Wild Hyacinth [Camassia Angusta (Engelm.· And A. Gray) Blank. (Liliaceae)], An Illinois Endangered Species, Kevin M. Franken, Janice M. Coons, Henry R. Owen, Eric L. Smith, John E. Ebinger

Henry R. Owen

Wild hyacinth (Camassia angusta) is a perennial species native to mesic prairies of the midwestern and south-central United States. In Illinois, the only extant population of this state-endangered species is in a small section of degraded black-soil prairie along a railroad track right-of-way south of Elwin, Macon County. The objectives of this study were to determine the population status, seed production, and effects of scarification and stratification on germination of C. angusta. The population was surveyed from 1990 to 2007. A survey of other plant species present was conducted in 1999. The site consisted of approximately 75% native and 25% …

Neurosteroid Replacement Therapy For Catamenial Epilepsy, Doodipala S. Reddy, Michael A. Rogawski

Michael A. Rogawski

Perimenstural catamenial epilepsy, the cyclical occurrence of seizure exacerbations near the time of menstruation, affects a high proportion of women of reproductive age with drug refractory epilepsy. Enhanced seizure susceptibility in perimenstrual catamenial epilepsy is believed to be due to the withdrawal of the progesterone-derived GABA-A receptor modulating neurosteroid allopregnanolone as a result of the fall in progesterone at the time of menstruation. Studies in a rat pseudopregnancy model of catamenial epilepsy indicate that following neurosteroid withdrawal there is enhanced susceptibility to chemoconvulsant seizures. There is also a transitory increase in the frequency of spontaneous seizures in epleptic rats that …

Metabolic Variability In Seafloor Brines Revealed By Carbon And Sulphur Dynamics, Samantha B. Joye, Vladimir A. Samarkin, Beth! N. Orcutt, Ian R. Macdonald, Kai-Uwe Hinrichs, Marcus Elvert, Andreas P. Teske, Karen Lloyd, Mark A. Lever, Joseph P. Montoya, Christof D. Meile

Karen Lloyd

Brine fluids that upwell from deep, hot reservoirs below the sea bed supply the sea floor with energy-rich substrates and nutrients that are used by diverse microbial ecosystems. Contemporary hypersaline environments formed by brine seeps may provide insights into the metabolism and distribution of microorganisms on the early Earth or on extraterrestrial bodies. Here we use geochemical and genetic analyses to characterize microbial community composition and metabolism in two seafloor brines in the Gulf of Mexico: an active mud volcano and a quiescent brine pool. Both brine environments are anoxic and hypersaline. However, rates of sulphate reduction and acetate production …

The Generation Of Influenza-Specific Humoral Responses Is Impaired In St6gal I-Deficient Mice., Thandi M. Onami, J Zeng, H. M. Joo, B. Rajini, J. P. Wrammert, M. Y. Sangster

Thandi M. Onami

Posttranslational modification of proteins, such as glycosylation, can impact cell signaling and function. ST6Gal I, a glycosyltransferase expressed by B cells, catalyzes the addition of alpha-2,6 sialic acid to galactose, a modification found on N-linked glycoproteins such as CD22, a negative regulator of B cell activation. We show that SNA lectin, which binds alpha-2,6 sialic acid linked to galactose, shows high binding on plasma blasts and germinal center B cells following viral infection, suggesting ST6Gal I expression remains high on activated B cells in vivo. To understand the relevance of this modification on the antiviral B cell immune response, we …

High-Throughput Protein Purification For X-Ray Crystallography And Nmr, Rachele M. Hendricks-Sturrup

Rachele M Hendricks-Sturrup

In structural biology, the most critical issue is the availability of high-quality samples. “Structural-biology-grade” proteins must be generated in a quantity and quality suitable for structure determination using X-ray crystallography or nuclear magnetic resonance. The additional challenge for structural genomics is the need for high numbers of proteins at low cost where protein targets quite often have low sequence similarities, unknown properties and are poorly characterized. The purification procedures must reproducibly yield homogeneous proteins or their derivatives containing marker atom(s) in milligram quantities. The choice of protein purification and handling procedures plays a critical role in obtaining high-quality protein samples. …

Mmtv-Wnt1 And -Dn89b-Catenin Induce Canonical Signaling In Distinct Progenitors And Differentially Activate Hedgehog Signaling Within Mammary Tumors, Brigitte Teissedre, Alicia Pinderhughes, Angela Incassati, Sarah J. Hatsell, Minoti Hiremath, Pamela Cowin

Minoti Hiremath

Canonical Wnt/b-catenin signaling regulates stem/progenitor cells and, when perturbed, induces many human cancers. A significant proportion of human breast cancer is associated with loss of secreted Wnt antagonists and mice expressing MMTVWnt1 and MMTV-DN89b-catenin develop mammary adenocarcinomas. Many studies have assumed these mouse models of breast cancer to be equivalent. Here we show that MMTV-Wnt1 and MMTV-DN89b-catenin transgenes induce tumors with different phenotypes. Using axin2/conductin reporter genes we show that MMTV-Wnt1 and MMTV-DN89b-catenin activate canonical Wnt signaling within distinct cell-types. DN89b-catenin activated signaling within a luminal subpopulation scattered along ducts that exhibited a K18+ER2PR2CD24highCD49flow profile and progenitor properties. In contrast, …

Fisher Management Regimes And Fisheries Governance In Floodplain Wetland Of Assam, Ganesh Chandra

Ganesh Chandra

Assam is endowed with copious aquatic wealth in the form of beels, swamps, ponds and rivers. The floodplain wetlands (beels) extending over one lakh hectare, constitute the most important fishery resource of the state. The beels are considered as one of the most productive ecosystems owing to their characteristic interactions between land and water system. These wetlands are the common property resource and under different management regimes. Livelihood of fishers’ family from time immemorial is dependent upon fishing in floodplain wetlands. Fishers include the actual fishermen belonging to the Schedule castes and the Maimal community of the district of Cachar. …

Stock Enhancement And Its Impact On The Productivity Of Haribhanga Beel In Assam, Ganesh Chandra

Ganesh Chandra

The floodplain wetlands (beels), extending over one lakh hectare, constitute the most important fishery resource of the Assam. The average productivity of Assam beels is 150-200 kg./ha/year. Many factors can be attributed for this situation, but inadequate auto stocking might be one of the basic reasons. To tide over this situation, rearing of seed in pens could be a viable alternative. Stock enhancement through pen culture was demonstrated by CIFRI at Haribhanga beel with three IMC. The fisher has adopted with modification using three Indian major carp and three exotic carp. A pen enclosure of 5000 m2 has been installed …

Thermoregulation Of Male Elaphe Spiloides In An Agriculturally-Fragmented Forest In Illinois, C. Drew Foster, Sarabeth Kleuh, Stephen J. Mullin

Stephen J. Mullin

Anthropogenic forest fragmentation increases the amount of edge habitat. Although edges are harsh environments for many native species, ratsnakes often prefer this habitat. We examined thermoregulatory effectiveness of Central Ratsnakes (Elaphe spiloides) using forest edges preferentially to determine if edge preference is driven by increased thermoregulatory efficiencies. Six male subjects were located every 1-2 days using radio-telemetry and temperature sensitive transmitters. Subjects did not thermoregulate more efficiently in edges than in forest. Snakes were thermoconformers in both habitat types suggesting edge preference might be driven by other factors.

Demographics Of A Geographically-Isolated Population Of Threatened Salamander (Caudata: Ambystomatidae) In Central Illinois, Stephen J. Mullin, Sarabeth Klueh

Stephen J. Mullin

Amphibian populations that use small isolated wetlands are often small in size, susceptible to stochastic extinction processes, and have little to no contact with other populations. One can ascertain the persistence of such populations only by obtaining data that allow the prediction of future changes in population’s size, and propensity to achieve a sustainable number of individuals. The number of metamorphosing larvae leaving a pond predicts the viability of a salamander population, and thus, the number recruited into the terrestrial adult population. The Jefferson Salamander, Ambystoma jeffersonianum, is a listed threatened species in Illinois, occurring at fewer than 15 ponds …

Seasonal Variation In The Maximum Rate Of Leaf Gas Exchange Of Canopy And Understory Trees In An Amazonian Semideciduous Forest, Kerrie M. Sendall, George L. Vourlitis, Francisco A. Lobo

Kerrie M Sendall

Leaf gas exchange, water potential, and specific leaf area of two tropical semi-deciduous tree species, Brosimum lactescens S. Moore and Tovomita schomburgkii Planch & Triana, were quantified to establish how these properties were affected by seasonal variations in rainfall and leaf canopy position. The study was conducted at a site near Sinop Mato Grosso, Brazil, which is located within the ecotone of savanna and tropical rain forest. Both species exhibited significant declines in leaf water potential (ΨL), specific leaf area, area- and mass-based light saturated photosynthesis and dark respiration, and maximum stomatal conductance during the dry-season, suggesting that leaf structural …
