Petrophysical and Mineralogical Research on the Influence of CO2 Injection on Mesozoic Reservoir and Caprocks from the Polish Lowlands

Afin de mener des recherches sur l'impact CO 2 ― roche - saumures, nous avons developpe un modele de simulation des conditions de gisement, pour lesquelles l'injection de dioxyde de carbone est envisagee. Des analyses ont ete effectuees sur des echantillons de carotte de roche provenant des reservoirs et de la couverture, preleves dans les forages de Pagorki (formations du Cretace) et de Brześc Kujawski (formations du Jurassique). Ces echantillons ont ete soumis, avant et apres les experiences, a des analyses petrographiques et mineralogiques classiques, afin de determiner les variations induites par les experiences. Les etudes menees ont montre que les reservoirs possedent de bonnes proprietes de stockage de CO 2 , et les roches de couverture de bonnes proprietes d'etancheite. L'experimentation realisee ne montre pas d'impact notable du gaz injecte sur les proprietes des roches reservoir analysees.
Evidence of the water-cage effect on the photolysis of NO 3 - and FeOH 2+ , and its implications for the photochemistry at the air-water interface of atmospheric droplets

Abstract. Experiments are conducted to determine the photolysis quantum yields of nitrate, FeOH 2+ , and H 2 O 2 in the bulk and at the surface layer of water. Results show that the quantum yields of nitrate and FeOH 2+ are enhanced at the surface compared to the bulk due to a reduced water-cage surrounding the photo-fragments ( • OH+ • NO 2 and Fe 2+ + • OH, respectively). However, no evidence is found for an enhanced quantum yield for H 2 O 2 at the surface. The photolysis rate constant distribution within nitrate, FeOH 2+ , and H 2 O 2 aerosols is calculated by combining the quantum yield data with Mie theory calculations of light intensity. Values for the photolysis rate constant of nitrate and FeOH 2+ are significantly higher at the surface than in the bulk due to enhanced quantum yields at the surface. The results concerning the rates of photolysis of these photoactive species are applied to the assessment of the reaction between benzene and • OH in the presence of • OH scavengers in an atmospherically relevant scenario. For a droplet of 1μm radius, a large fraction of the total • OH-benzene reaction (15% for H 2 O 2 , 20% for nitrate, and 35% for FeOH 2+ ) occurs in the surface layer, which accounts for just 0.15% of the droplet volume. By neglecting the surface effects on photochemistry, the rate of the important reactions could be underestimated by a considerable amount.
Additives Promote Adventitious Buds Induction from Stem Segments of Bitter Melon (Momordica charantia L.)

The effects of thidiazuron (TDZ), silver nitrate (AgNO 3 ) and triacontanol on adventitious buds induction from stems of balsam pear ( Momordica charantia L.) were investigated. It was found that TDZ was necessary for bud development and the higher concentration of it could induce adventitious buds efficiently, while 0.1 mg/L was the best concentration to induce adventitious buds considered effect and cost. Bud formation was significantly affected by AgNO 3 and triacontanol. Best results were obtained at concentration of 2.0 mg/L separately.
Crisis Preparedness among Clinical Staff: A Brief Survey in an Iranian Context

Background and Objectives: During crisis, hospitals have great responsibility in saving life and protect health of the damaged individuals. Fulfilling this responsibility relies on preparedness of hospital staff, particularly the clinicians to face the relevant challenges. Given the lack of adequate information on the topic from Iran, the present study aimed to explore the technical crisis preparedness of healthcare staff in a sample Iranian hospital. Methods: A cross-sectional study was conducted. A sample of 265 clinicians were randomly selected from among clinicians of a hospital in Tehran (Iran Capital), based on Cochran's formula. Data were collected using a researcher-made inventory containing 28 multiple-choice questions related to the technical preparedness and three questions related to the attitudes of respondent towards relevant training programs. Data were summarized using descriptive statistical methods and analyzed by Mann-Whitney and Kruskal-Wallis tests. Findings: The respondents expressed a moderate self-assessment of their technical crisis preparedness. Females, the age group of 51-60 years, work experience group of 21-30 years, married participants showed a significantly higher level of technical preparedness, compared with other respective groups (P < 0.05). The “ability to perform duties” was expressed as a major motivation to take part in crisis preparedness training programs, followed by “high probability of crisis happening”. On the other hand “lack of time” and “poor work conditions” were expressed as the major factors negatively affecting clinicians’ willingness to participate in training programs. Conclusions: Our result highlights the significance of assigning crisis management to the adequately experienced individuals. Training programs and maneuvers should be constantly held to provide clinicians the opportunity to enhance their crisis preparedness. Specific organizational arrangements are required to be made to encourage staff take the advantages of training opportunities and help them overcome the relevant barriers.
COMPETITION FOR PREY BETWEEN ANTS AND BURYING BEETLES (NICROPHORUS SPP): DIFFERENCES BETWEEN NORTHERN AND SOUTHERN TEMPERATE SITES.

Burying beetles (Silphidae: Nicrophorus) utilize small vertebrate carcasses which can be quickly buried or rolled down a hole and concealed. Because carrion is also used by other invertebrates and vertebrates, burying beetles may be in competition with species of a wide variety of taxa for access to carcasses. For example, calliphorid flies are often first to oviposit on carrion and if the eggs are not detected and destroyed by Nicrophorus the carcass may be consumed by developing fly larvae, causing the beetles to abandon the resource. One aspect of resource competition in Nicrophorus that has not been examined concerns interactions between burying beetles and ants (Arnett 1946). Ants are abundant, omnivorous scavengers in many habitats; ant colony size is often large and many species have swift recruitment systems that would allow them to occupy and defend small vertebrate prey. Ant species diversity and abundance are known to follow a latitudinal gradient (Kusnezov 1957, Wilson 1971, Jeanne 1979), and therefore the predatory or scavenging habits of ants may exert different effects on the ability of northern and southern temperate Nicrophorus species to control small vertebrate carrion. In this paper we report on the results of a study examining competitive interactions between burying beetles and ants at northern and southern sites in North America.
Distribution of Oecomys catherinae Thomas, 1909 (Rodentia: Cricetidae) in northeastern Brazil with karyotypical and morphometrical notes

The genus Oecomys Thomas, 1906 is currently composed of 16 species with unclear taxonomy and poorly known geographic limits. O. catherinae Thomas, 1909 is known to occur within the Brazilian Atlantic Forest from the states of Santa Catarina to Pernambuco (where the northernmost previously known specimen of Oecomys in the Atlantic forest was recorded), and along riverine forest into the Cerrado. To gain a greater understanding of its geographical and ecological distribution (mainly in Northeastern Brazil) and of its taxonomic characterization, we provide a short review of karyotypical and morphometrical data from specimens collected within the distribution range of the species. Specimens presented 2n = 60 and AN varying between 62 and 64. A table with external and cranial measurements of the analyzed specimens is provided. In this paper we also report the presence of O. catherinae in the semi-deciduous forests of the state of Paraiba, representing the northernmost records of the species in the Atlantic forest and thereby extending its known geographical limits.
Dynamic Probit Models and Financial Variables in Recession Forecasting

In this paper, various financial variables are examined as predictors of the probability of a recession in the USA and Germany. We propose a new dynamic probit model that outperforms the standard static model, giving accurate out-of-sample forecasts in both countries for the recession period that began in 2001, as well as the beginning of the recession in 2008. In accordance with previous findings, the domestic term spread proves to be an important predictive variable, but stock market returns and the foreign term spread also have predictive power in both countries. In the case of Germany, the interest rate differential between the USA and Germany is also a useful additional predictor. Copyright © 2009 John Wiley & Sons, Ltd.
Reported Impacts of Coaches’ Facework on Motivation and Credibility

Coaches’ credibility and athletes’ motivation were examined in the context of the coaches’ facework skills. Young and older adults were surveyed with questionnaires that looked at facework, credibility, and motivation in order for them to reflect on their past experiences with coaches. Analysis revealed that the perceived credibility of the coaches by their athletes was significantly correlated with the coaches’ reported facework during performance feedback. In contrast, facework showed no significant correlation with the athletes’ reported levels of motivation. Together these findings show that the facework of coaches holds differing importance for different outcomes in the coaching process and can affect the potential of the athletes’ growth in sport.
Iodine-mediated coastal particle formation: an overview of the Reactive Halogens in the Marine Boundary Layer (RHaMBLe) Roscoff coastal study

Abstract. This paper presents a summary of the measurements made during the heavily-instrumented Reactive Halogens in the Marine Boundary Layer (RHaMBLe) coastal study in Roscoff on the North West coast of France throughout September 2006. It was clearly demonstrated that iodine-mediated coastal particle formation occurs, driven by daytime low tide emission of molecular iodine, I2, by macroalgal species fully or partially exposed by the receding waterline. Ultrafine particle concentrations strongly correlate with the rapidly recycled reactive iodine species, IO, produced at high concentrations following photolysis of I2. The heterogeneous macroalgal I2 sources lead to variable relative concentrations of iodine species observed by path-integrated and in situ measurement techniques. Apparent particle emission fluxes were associated with an enhanced apparent depositional flux of ozone, consistent with both a direct O3 deposition to macroalgae and involvement of O3 in iodine photochemistry and subsequent particle formation below the measurement height. The magnitude of the particle formation events was observed to be greatest at the lowest tides with the highest concentrations of ultrafine particles growing to the largest sizes, probably by the condensation of anthropogenically-formed condensable material. At such sizes the particles should be able to act as cloud condensation nuclei at reasonable atmospheric supersaturations.
Simulation studies on the electron cloud build-up in the elements of the LHC Arcs at 6.5 TeV

The formation of electron clouds in the arcs of the Large Hadron Collider (LHC) has been identified as one of the main limitations for the performance of the machine. In particular, the impacting electrons can deposit a significant power on the cold beam screens of the LHC superconducting magnets, which translates into a significant heat load for the cryogenic system. A detailed model of the e-cloud formation in the different elements of the LHC arc half-cell has been developed using the PyECLOUD simulation code. The model includes the main dipole and quadrupole magnets, shorter corrector magnets and drift spaces. Particular care was taken to correctly model the impact of the photoelectrons produced by the beam synchrotron radiation. For this purpose, we reviewed the available literature on the characterization of the LHC beam screen surface in terms of reflectivity and photoelectron yield and we defined the necessary steps to obtain the photoemission model in the format required in input by the PyECLOUD code. This allowed assessing element by element the impact of the photoemission process on the e-cloud formation. Simulation results could be compared with heat load measurements collected at the LHC during operation with 25 ns bunch spacing.
The nature of interaction between Israeli entrepreneurs and investment capital available within and from outside Israel

Israel is a small country that has rapidly become a global leader in production of hightech goods. Supporting this industry is strong investment and high levels of entrepreneurship. Some scholars suggest a close similarity between the Israeli Venture Capital industry and that of Silicon Valley. To validate that claim I have closely replicated a network model developed for entrepreneur-venture capital interactions in Silicon Valley and applied it to Israel. This has been achieved through mapping the linkages with a 3D network modelling software (Pajek) between biotech firms created since 2000 and other players in the Israeli market such as venture capital funds, universities and government institutions. Information gathered on the entrepreneurs responsible for the biotech firms creation suggests that the majority are either professors at research institutes or hold a doctorate degree, suggesting strong linkages between the entrepreneurs and their research institutes. Many firms are also found to employ professional management teams. The matrix of inter-connections and supporting institutions suggests that biotech research institutions have a strong focus on fostering commercialization of new technologies. There is also abundant support for high-tech and venture capital from the Israeli government, which is a point of difference between Israel and Silicon Valley. Taken together the strong presence of institutions and of government support may explain,at least in part, the attractiveness of Israel for investors despite the country’s precarious and uncertain condition as one of the global war and conflict hot spots. Introduction Israel is a small country in the Middle-East surrounded by nations and ideologies which have openly proclaimed and sought its destruction since it’s inception in 1948. Since that time Israel has been embroiled in numerous international and domestic conflicts: 1 1948 the War of Independence 2 1956 the Sinai War 3 1967 the Six Day War 4 1973 the Yom Kippur War 5 1976 the Entebbe Raid 6 1981 the air raid on Iraq nuclear facilities 7 1982 the Lebanon War 8 1987 the First Palestinian Intifada 9 1991 the Gulf War 1
Injury Severity Analysis of Crashes in Right-Turn Lanes at Signalized Intersections

This study investigated the level of injury severity in crashes in right-turn lanes at signalized intersections. It used a dataset of 1900 injuries occurring at 275 signalized intersections in the Las Vegas area in the 2003 to 2005 period. An advanced random parameter binary logit model was used to determine the factors that significantly influence injury severity with PDO and severe injury in right-turn lanes. A comparison of this model with the traditional fixed parameter model was made to account for the unobserved heterogeneity. It was comparable to the two-level binary logistic model, which accounts for cross-group heterogeneity. The analysis showed that the following factors lead to a significantly higher likelihood of severe injury: rear-end crashes, the involvement of a vehicle going through the intersection, stopped and parked vehicles on main and minor streets, length of corner clearance, number of through lanes on minor streets, and intersection angle.
Quantitative Prediction of Twitter Message Dissemination: A Machine Learning Approach

Predicting the popularity of contents in social networks is quite important for several applications such as viral marketing, news propagation and personalization. In this work, we developed an statistical learning approach to predict the popularity of tweets in the twitter social network. We extracted several user-based, tweet-based and network-based features from each tweet and adopted several classifiers to predict the popularity of tweets. We model this problem with a binary classification problem where popular tweets are considered as the positive and non-popular tweets are considered as the negative class. Popularity is defined by a threshold which indicates how many time a tweet is retweeted. We defined several popularity thresholds and examined the performance of different classifiers based on different threshold values. Our experimental results show that there is no global best classifier for the problem of popularity prediction in twitter but depending on the dataset, popularity threshold and our interest, we can adopt an optimal classifier with a proper set of features for this task.
Job History, Work Attitude, and Employability

We study whether employment history can provide information about a worker’s noncognitive skills—in particular about “work attitude,” or the ability to work well and cooperatively with others. Our hypothesis is that, holding all else equal, a worker’s frequent job changes can indicate poorer work attitude, and that this information can be transmitted in labor markets through employment histories. We provide support for this hypothesis across three studies that employ complementary field, lab and survey experiments. First, using a laboratory labor market in which the only valuable characteristic of workers is their reliability in cooperating with an employer’s effort requests, we demonstrate that prior employment information allows employers to screen for such reliability and allows high-reliability workers to obtain better employment outcomes. Second, we conduct a field experiment in which we vary the frequency of job changes in fictitious job applicants’ resumes. Those applicants with fewer job changes are more likely to receive callbacks from prospective employers. A third survey experiment with human resource professionals confirms that the resume manipulations in the field study create different perceptions of work attitude. Our work highlights the potential importance of job history as a signal of worker characteristics, and points to a cost for workers of frequent job changes.
Students' Misconceptions about the Ozone Layer and the Effect of Internet-Based Media on It.

Living beings and the environment are in constant interaction with one another. The physical, chemical and biological factors that constitute any given environment have a unique impact on particular habitats (Ozkaya & Usak, 2009). Up until the 1980s, the environment had been an ordinary subject, of no great concern. Once people began to understand the seriousness of air pollution and its effects on human health, it became a popular topic in the media. For example, the wide spread attention given to the disappearance of forests in Scandinavia due to acid rain has raised public awareness about this issue in places far removed from the site of actual occurrence. The depletion of the ozone layer and the increased cases of skin cancer that have emerged as a result have caused a great deal of concern among people. Today, even young people have begun to realize that the sustainability of the environment is being threatened in various ways (Hillman, Stanisstreet, & Boyes, 1996).
Randomized controlled trial of the active music engagement (AME) intervention on children with cancer

Background: Coping theorists argue that environmental factors affect how children perceive and respond to stressful events such as cancer. However, few studies have investigated how particular interventions can change coping behaviors. The active music engagement (AME) intervention was designed to counter stressful qualities of the in‐patient hospital environment by introducing three forms of environmental support.
Volatile organic compounds and isoprene oxidation products at a temperate deciduous forest site

Biogenic volatile organic compounds (BVOCs) and their role in atmospheric oxidant formation were investigated at a forest site near Oak Ridge, Tennessee, as part of the Nashville Southern Oxidants Study (SOS) in July 1995. Of 98 VOCs detected, a major fraction were anthropogenic VOCs such as chlorofluorocarbons (CFCs), alkanes, alkenes and aromatic compounds. Isoprene was the dominant BVOC during daytime. Primary products from BVOC oxidation were methylvinylketone, methacrolein and 3-methylfuran. Other compounds studied include the BVOCs α-pinene, camphene, β-pinene, p-cymene, limonene and cis-3-hexenyl acetate and a series of light alkanes, aromatic hydrocarbons and seven of the CFCs. The correlation of meteorological parameters, with the mixing ratios of these different compounds, reveals information on atmospheric oxidation processes and transport. Long-lived VOCs show very steady mixing ratio time series. Regionally and anthropogenically emitted VOCs display distinct diurnal cycles with a strong mixing ratio decrease in the morning from the breakup of the nocturnal boundary layer. Nighttime mixing ratio increases of CFCs and anthropogenic VOCs are suspected to derive from emissions within the Knoxville urban area into the shallow nocturnal boundary layer. In contrast, the time series of BVOCs and their oxidation products are determined by a combination of emission control, atmospheric oxidation and deposition, and boundary layer dynamics. Mixing ratio time series data for monoterpenes and cis-3-hexenyl acetate suggest a temporarily emission rate increase during and after heavy rain events. The isoprene oxidation products demonstrate differences in the oxidation pathways during night and day and in their dry and wet deposition rates.
Screening Of Salt Pans Actinomycetes For Antibacterial Agents

The actinomycetes exist in various habitats in nature. The terrestrial ones from the soil have been extensively used for the production of secondary metabolites useful to human. However the aquatic counterparts have reminded relatively unknown and unexploited. The soil from the saltpan regions of Cuddalore and Parangipettai (Porto-novo) were screened for the isolation of actinomycetes. In this investigation 17 actinomycete isolates were obtained and were screened for primary antibacterial activity. Three actinomycetes namely two species of Streptomyces and one species of Saccharomonospora collected and showed promising antimicrobial activity against eight test organisms. Secondary screening of the actinomycetes isolates also indicated positive antibacterial activity against Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Vibrio cholerae, salmonella typhi, Staphylococcus aureus, and Shigella dysenteriae the present study indicate that the saltpan soil harbors diverse species of actinomycetes possessing potent antibacterial activity, which could be later scaled up for large scale commercial production of antibiotics if found suitable. The extraction of antibacterial activity in various solvents indicated that the active organic moiety responsible for antibacterial activity was soluble in aniline and ethyl acetate was found active against the test microorganisms.
