Heavy metal resistance by two bacteria strains isolated from a copper mine tailing in China

Two highly heavy metal resistant indigenous bacterial strains, DX-T3-01 and DX-T3-03, were isolated from the biggest tailing in Asia-Dexing copper mine 4# tailing. The strain DX-T3-01 exhibited high tolerance to cadmium: 10 mM Cd2+ with yeast tryptophan peptone glucose (YTPG) agar plates and 18 mM in liquid medium. The strain DX-T3-03 was highly resistant to zinc and could endure 35 mM Zn2+ with YTPG agar plates and 40 mM in liquid medium. They also showed tolerance to other heavy metals, such as copper, lead and nickel. The morphology, physiological and biochemical characteristics of the two strains were examined by scanning electron microscope (SEM) and BIOLOG. The strains showed different metabolic patterns of carbon sources. The strain DX-T3-03 had a larger range of antibiotic resistance than DX-T3-01. On the basis of 16S rDNA sequencing, the two strains were identified as Ralstonia pickettii strain DX-T3-01 and Sphingomonas sp. strain DX-T3-03, respectively. This study supplied potential bacterial materials for tailing bioremediation in the future. Key words: Heavy metals, tolerant bacteria, isolation, mine tailing.

Comparative Studies on the Production and Assay of Interferon

Interferon was produced in chick embryo cell cultures orjn chick embryos by five viruses and in mouse embryo cell cultures or mouse lungs by two viruses. The slopes of the log dose response lines for the five chick interferons were compared by using vaccinia virus as the assay virus. Analysis of variance showed that they did not differ significantly. Partially purified interferon gave the same slope as the crude preparations. These findings allowed a comparison to be made of relative yields of interferon induced by different viruses in the same cell system. Viruses differed widely in their ability to induce interferon. Chikungunya virus induced about 70 times more interferon than did vaccinia or Newcastle disease virus and 2.6 times more interferon than Kumba virus. The slopes of the log dose response lines for two interferon preparations were compared by using Chikungunya virus as the assay virus. Analysis of variance showed that they were not significantly different. A comparison of the vaccinia and Chikungunya assays for interferon showed that the Chikungunya assay was approximately 2-9 times more sensitive when the amount of interferon depressing the plaque count by 50 yo (PDD 50 doses) were compared. An analysis of variance showed that the difference in slope between the two assays was small but approaching significance. Mouse interferon, induced by two viruses, yielded parallel dose response lines. However, the slope of the curves for mouse interferon was significantly different from that for chick interferon. Because of this difference in slope, interferon production by the same virus in the two cell types could not be validly compared.
O C ] 2 2 A pr 2 01 5 Control of Generalized Energy Storage Networks ∗

The integration of intermittent and volatile renewable energy resources requires increased flexibility in the operation of the electric grid. Storage, broadly speaking, provides the flexibility of shifting energy over time; network, on the other hand, provides the flexibility of shifting energy over geographical locations. The optimal control of general storage networks in uncertain environments is an important open problem. The key challenge is that, even in small networks, the corresponding constrained stochastic control problems with continuous spaces suffer from curses of dimensionality, and are intractable in general settings. For large networks, no efficient algorithm is known to give optimal or near-optimal performance. This paper provides an efficient and provably near-optimal algorithm to solve this problem in a very general setting. We study the optimal control of generalized storage networks, i.e., electric networks connected to distributed generalized storages. Here generalized storage is a unifying dynamic model for many components of the grid that provide the functionality of shifting energy over time, ranging from standard energy storage devices to deferrable or thermostatically controlled loads. An online algorithm is devised for the corresponding constrained stochastic control problem based on the theory of Lyapunov optimization. We prove that the algorithm is near-optimal, and construct a semidefinite program to minimize the sub-optimality bound. The resulting bound is a constant that depends only on the parameters of the storage network and cost functions, and is independent of uncertainty realizations. Numerical examples are given to demonstrate the effectiveness of the algorithm.
Photobacterium histaminum sp. nov., a Histamine-Producing Marine Bacterium

A total of 23 strains of halophilic histamine-producing bacteria previously isolated from marine fish and seawater were studied phenotypically, genotypically, and phylogenetically. These organisms are facultatively anaerobic, gram-negative, short rods that are motile by means of one to three unsheathed polar flagella. They are mesophilic and nonluminescent, produce oxidase, utilize d-glucose but not d-mannitol as a carbon and energy source, and accumulate poly-β-hydroxybutyrate. The guanine-plus-cytosine contents of the DNAs are ca. 41 mol%. Genomic DNA hybridization experiments revealed that some of the isolates exhibited low levels of reassociation (less than 40%) with previously described Photobacterium species. 16S rRNA gene sequence information confirmed the phylogenetic position of one of the isolates, strain C-8T (T = type strain), as a member of the genus Photobacterium. Therefore, we concluded that these organisms are members of a new species of the genus Photobacterium and propose the name Photobacterium histaminum sp. nov. for them. The type strain is strain C-8 (= JCM 8968).
Factors affecting the services sector growth in Pakistan: A time varying parametric approach

Abstract. This empirical study followed time varying parametric approach (Kalman Filter) to find out relevant determinants of Pakistan’s services sector’s growth. To our best of knowledge, no author has made such study that could collect a number of variables from existing empirical literature and capture the impact of structural changes on relevant determinants of services sector growth in Pakistan while employing Kalman Filtering approach. Current study bridges this gap. Annual data was taken from World Development Indicators (2014) during period 1976-2014. Main findings of the study are that rolling regression estimates of explanatory variables justify the use of Kalman filtering approach. The state space Results show that foreign direct investment and gross national expenditures are positive and significant determinants of services sector growth while inflation, domestic credit to private sector, gross fixed capital formation, and remittances received and trade openness have negative impact on services sector growth. One step ahead graph inflation, domestic credit to private sector, foreign direct investment, gross national expenditures, gross fixed capital formation, remittances received and trade openness indicate that model estimated was stable as critical bounds(dotted line) in graph 2 are not crossed by central line. Based on empirical findings, it is recommended the concerned authorities to augment gross national expenditures and foreign direct investment to achieve long run services sector growth for better economic growth in country.

A Meta-Analysis of Electronic Word-of-Mouth Elasticity

The authors conduct a meta-analysis on the effect of electronic word of mouth on sales by examining 51 studies (involving 339 volume and 271 valence elasticities) and primary data collected on product characteristics (durability, trialability, and usage condition), industry characteristics (industry growth and competition), and platform characteristics (expertise and trustworthiness). Their analysis reveals that electronic word-of-mouth volume (valence) elasticity is . 236 (.417). More importantly, the findings show that volume and valence elasticities are higher for privately consumed, low-trialability products that operate in less competitive industries and whose reviews are carried on independent review sites. Furthermore, volume elasticities are higher for durable goods and for reviews on specialized review sites, whereas valence elasticities are greater for community-based sites. Drawing on the results, they discuss several implications for managers and researchers and explain why valence elasticities are often found to be insignificant. Finally, they propose numerous directions for future research in the area on the basis of their findings.
THE INTERPERSONAL-PSYCHOLOGICAL THEORY OF SUICIDE AND EXPOSURE TO VIDEO GAME VIOLENCE

According to the Interpersonal-Psychological Theory of Suicide (IPTS), individuals become capable of withstanding the pain and fear associated with a suicide attempt through habituation to painful and/or frightening stimuli. This capability, referred to as the acquired capability for suicide, is composed of both pain tolerance and fearlessness about death. Although most often these two components have been confounded in the literature, recent investigations utilizing the IPTS have found differential relationships between these components and specific life experiences. In the current study, we investigated the relationship between exposure to violent video games and both components of acquired capability. Given that a limited number of studies have found relationships between suicide ideation and excessive video game play, we also investigated the relationships among violent video game exposure, thwarted belongingness, perceived burden-someness, and passive suicide ideation. We hypothesized that exposure t.
Molecular characterization of segment 6 of bluetongue serotype 16 of sheep origin from India.

Received: Revised: Accepted: 2013–12–12 2013–12–21 2013–12–22 The bluetongue (BT) is a Culicoides vector transmitted viral disease of ruminant. The disease is endemic in India and many other countries of the world. In the present study, the bluetongue virus (BTV) isolate BT16/07, originally isolated from sheep, was cultivated in BHK–21 cell line and showed the characteristic cytopathic effect (CPE) within 48 hours. The viral nucleic acid (dsRNA) was extracted using Trizol method and tested in RNA–poly acrylamide gel electrophoresis (RNA–PAGE). The RNA–PAGE analysis of viral nucleic acid revealed a BTV– characteristic 3:3:3:1 migration pattern. The cDNA prepared from viral nucleic acid was subjected to non–structural gene 1 (NS1) based group–specific PCR to confirm the genetic nature of the virus. The group–specific NS1 gene based PCR showed a single 366bp amplicon and confirmed the isolate as BTV. The serotype specific PCR was conducted using VP5 gene specific primers for serotyping of the BT16/07 isolate. The serotype–specific PCR, using BTV16 VP5 gene–specific primer, showed a single amplicon of 757bp. The remaining BTV serotype–specific primers fail to amplify the respective gene sequence. The VP5 gene–specific PCR amplicon was cloned and subsequently sequenced. The nucleotide sequence obtained was subjected to in–silico restriction enzyme analysis and phylogenetic analysis. The phylogenetic tree, sequence identity analysis and in–silico restriction enzyme analysis (REA) indicate the eastern origin of the BT16/07 isolate.

The Vitality of the Braille in Enabling Inclusion for the Visually Impaired in Regular Secondary Schools in the North West Region of Cameroon

The inclusion of the visually impaired in regular schools necessitates that braille is provided to them. Nonetheless, there is a likelihood or possibility in actuality for the visually impaired not being included in the learning that goes on in the regular secondary schools unless appropriate measures are taken to ensure their inclusion. This article which is an excerpt of an ongoing qualitative research in the North West region of Cameroon examines the braille provisioning in regular secondary schools, the approaches used in the provision of this resource and the appropriate measure to fully include the visually impaired. An examination of the braille, the appropriate measures to fully include the visually impaired leaves the conclusion that there is a prospect and likelihood for the visually impaired to be educated in regular secondary schools and that it is important for the regular schools in Cameroon to build on the existing provisioning of the braille. This is owing to the fact that this resource in actual fact is however what is currently available and also the working initiative in the education of the visually impaired.
SD Small Decrease N Neutral LI Large Increase MI Medium Increase

This paper presents fuzzy logic controlled dc-dc boost converter based Dynamic Voltage Restorer (DVR) to compensate severe voltage sag problems in an electrical system. DVR absorbs real power from battery to compensate voltage sags in the system. This condition causes reduction in voltage magnitude of dc-link capacitor. Additionally, DVR requires large dc capacitors to compensate long and severe voltage sags in the system. In this study, dc-dc boost converter is connected to DVR for keeping dc link voltage constant. For this propose, a control algorithm based on Fuzzy Logic (FL) control is developed for dc-dc boost converter. The main contribution of this study is that Fuzzy Logic (FL) is firstly used to generate reference signal for PWM signals of dc-dc converter applied in DVR. FL is a very flexible controller which keeps the dc link voltage constant during voltage sag. The performance results of proposed study are verified with PSCAD/EMDTC.
User awareness concerning feedback data and input observations used in reanalysis systems

Abstract. A web-based survey to assess the benefits and gaps in reanalyses as part of growing climate services was carried out in 2013–2014. The survey elicited responses from about 2500 users of climate information. One of the eleven survey points specifically addressed the observations used in reanalysis, with a multiple-choice question "Have you used reanalysis input observations and feedback data? ". Almost half of the respondents admitted to not knowing what such data were about. Among the others, specific queries asked for these observations to be made available more openly. This paper summarizes the main findings in regard to use of existing reanalyses as well as user awareness and needs in regard to reanalysis feedback data and input observations. In the future, the information obtained via the survey makes it possible to perform various statistically robust analyses addressing different aspects of the use of reanalysis data.
Photocatalytic Reduction of Aqueous Cr(VI) with CdS under Visible Light Irradiation: Effect of Particle Size

Stringent environmental standards have made the removal of Cr(VI) from water an important problem for environmental scientist and engineering. Heterogeneous photocatalysis using suspended photocatalyst is an interesting technique to consider for this application. In this work, the influence of particle size of suspended CdS on the photocatalytic reduction of aqueous Cr(VI) ion was investigated. The efficiency of Cr(VI) reduction was monitored through UV-visible analysis. The experimental results showed that the nanoparticle size has a dramatic effect on the adsorption and reduction of Cr(VI). As surface area increased from 44.2±0.6 to 98.7±0.5 m 2 /g due to particle size reduction, the rate of Cr(VI) reduction nearly doubled in the first 20 min of visible light irradiation. The results evidenced the inverse relationship between the apparent reduction rate constant and the CdS particle size. Conversely, the half-life (t 1/2 ) period of the photocatalytic reduction has a direct relationship with CdS particle sizes. Copyright © 2017 BCREC GROUP.

Volumetric and Viscometric Study of MCM-41 in the Presence of Nicotinamide (A Hydrotropic Agent) in Ethanol

Mesoporous MCM-41 was synthesized by using cetylhexadecyltrimethyl-ammoniumbromide (CTAB) and tetraethylorthosilicate (TEOS). The synthesized MCM-41 was characterized by XRD, Fourier Transformed-Infrared spectroscopy (FT-IR), high resolution transmission electron microscopy (TEM) and scanning electron microscopy (SEM). The characterized showed that MCM-41 possessed high crystallinity, mesospheric morphology and porous structure to be potentially used as a catalyst, drug delivery system. Since no physico-chemical properties like density and viscosity data are available for MCM-41, the present work has been undertaken to carry out the density and viscosity measurements of the solutions of MCM-41 in the presence of nicotinamide, a hydrotropic agent in ethanol at temperatures ranging from 298.15 K to 313.15 K at an interval of 5K.The results have been discussed in the light of molecular interactions.
Is Nature Continuous or Discrete, and How Can These Two Conceptions be Reconciled?

Our contention, is that reality is actually analog, but that at a critical limit, as when the Octonian gravity condition kicks in, that for a time it appears discrete. This due to al phase transition at the start of the big bang. Our second consideration is, that symmetry breaking models, i.e. the Higgs boson are not necessary for the formation of particles with mass just before Octonionic gravity, arise in pre Planckian physics models without a potential. Finally, the necessity of potentials for pre Octonionic gravity physics can be circumvented via Sherrer k essence physics.
Greater bioavailability of chelated compared with inorganic zinc in broiler chicks in the presence or absence of elevated calcium and phosphorus

Animal diets often contain antagonists that reduce Zn bioavailability, thereby creating a deficiency. The bioavailability of Zn chelated to 2-hydroxy-4-(methylthio)butanoic acid (chelated Zn) was compared with Zn sulfate in broiler chicks in two dietary conditions: a Zn-deficient corn-soybean meal (C-SBM) diet and a Zn-deficient C-SBM diet containing elevated Ca and P as antagonists. In experiment 1, chicks were fed a common diet (19 mg Zn/kg diet) through day 8, and then a Zn-unsupplemented (21 mg Zn/kg diet; 0.82% Ca, 0.47% available P) C-SBM basal or the basal supplemented with 5, 10, 15, 20, or 30 mg Zn/kg diet as chelated Zn or Zn sulfate for 6 days. Common-intercept, multiple linear regression slope-ratio analysis indicated significantly greater Zn bioavailability for chelated Zn relative to Zn sulfate as judged by: total tibia Zn (µg) (161%; =0.001); tibia zinc concentration (µg/g; 165%, =0.0009); and small intestinal metallothionein mRNA expression (248%; =0.009). In experiment 2, chicks were fed a Zn-deficient (24 mg Zn/kg diet) common diet, then fed a C-SBM basal elevated in Ca and P (27 mg Zn/kg diet; 1.2% Ca, 1% available P), or the basal supplemented with 15 or 30 mg Zn/kg diet as Zn sulfate or 7.5, 15, or 30 mg Zn/kg diet as chelated Zn. Zn sulfate was antagonized to a greater extent than Zn chelate. Bioavailability of chelated Zn relative to Zn sulfate was 441% ( =0.0063; µg total tibia Zn), 307% ( =0.0066; µg/g tibia Zn), and 426% ( =0.0041; metallothionein). Thus, feeding chelated Zn offers advantages over inorganic Zn, especially in diets containing high levels of Ca and P, which is a common occurrence in pet food and in livestock diets. antagonism, broilers, chelate, metallothionein, minerals
Surprises in scheduled macroeconomic announcements: Why do they move the bond market?

It is well known that information arrival has an impact on prices volatility, and trading volume in financial markets. Scheduled macroeconomic announcements, such as monthly employment figures, consumer prices, or building permits, stand out from the steady flow of information. Several studies show that these releases have a very distinct impact on prices. While most of these studies try to find out which releases are significant, considerably less effort has been devoted to the question what makes some releases so important in contrast to others that seem to attract no attention. Papers addressing this question emphasize the content of releases. For example, Edison (1996) discriminates between news related to unexpected inflation and those related to unexpected changes in economic activity. Investigating intraday T-bond futures price responses to surprises in scheduled macroeconomic releases, this paper presents evidence that the type of information is relevant. More specifically, the results suggest that the sequence of releases within a given content category helps to explain their relative importance. In other words, if market participants have already observed some figures on which they can base their assessment of a particular aspect of the economy, then the additional information of another related report should be small, and thus, its impact on prices.
