New physics searches with heavy flavour observables at ATLAS

New and recent results from the programme of studies in electroweak physics with open beauty performed by the ATLAS experiment are presented. Flavour-Changing-Neutral-Current (FCNC) processes are sensitive to New Physics contributions, in particular through additional electroweak loop amplitudes. The angular analysis of the decay of $B_d \to K^* \mu \mu$ for a number of angular coefficients are measured as a function of the invariant mass squared of the di-muon system for data collected by the ATLAS experiment at a centre-of-mass energy $\sqrt{s}$ = 8 TeV. A comparison is made to theoretical predictions, including for the observable $P^\prime_5$, for which there has been recent tension between theory and experiments.
CRUDE OIL FOULING: PETRONAS REFINERIES EXPERIENCE

Managing crude oil fouling has been a challenge in PETRONAS refineries. Over the past several years, numerous initiatives have been conducted in order to have better control of the situation [1][2][3][4]. The control strategy currently implemented is to periodically clean the heat exchanger based on the heat exchanger monitoring parameter and supported by antifouling chemical injection program. A review was conducted in one of PETRONAS’ refineries in order to come up with a better fouling control strategy. The review is separated into two parts. Firstly, the plant operational data for two selected hot pre-heat exchanger trains was analyzed. From the analysis, deposition build-up is apparent for only one exchanger train despite both trains receiving the same crude blend. It seems that there are several significant parameters which caused one of the exchanger to fall into fouling threshold region. EXPRESS [5] software was used to evaluate the fouling threshold region for the heat exchanger. Secondly, foulant sample obtained from the heat exchangers were subjected to analytical testing to investigate the constituent of the foulant. The analyses show that it is mainly organic in nature with a minor portion of the inorganic content made up of mostly corrosion products, salt and sand.
Modern Economic Growth and Quality of Life: Cross Sectional and Time Series Evidence

To what extent are improvements in quality of life (material living levels, health, education, political and civil rights, happiness, and the like) associated with economic growth? International comparisons of quality of life (QoL) conditions almost always point to a strong positive association with real GDP per capita. Historical experience, however, frequently belies the results of these comparisons. More often than not the timing of various improvements in QoL, material living levels excepted, is different from that in real GDP per capita – some indicators preceding, others following. Moreover, the sequence of improvements in various aspects of QoL is not always the same from one part of the world to another. And sometimes, as in the case of happiness and life satisfaction, QoL indicators remain unchanged despite a doubling or more of real GDP per capita. In contrast to the results of simple international point-of-time comparisons, history suggests that improvements in many realms of life are not an automatic result of economic growth.
Psychological Capital Questionnaire - Short Version (PCQ-12): evidence of Validity of The Brazilian Version

Abstract This study aimed to show evidence of validity for the Brazilian short version (12 items) of the Psychological Capital Questionnaire (PCQ-12). Three independent samples participated in the study, totaling 1771 subjects (64.3% women, 32.9% men and 2.9% undeclared), aged 18-79 years (M = 38.59, SD = 12.98). Confirmatory factor analyses showed acceptable adjustment indices for the four-factor structure (self-efficacy, hope, resilience and optimism) and for a second-order structure with a general factor of psychological capital explaining the four primary factors. Multi-group confirmatory factor analyses found configural, metric and scalar invariance of the measure for the different samples as well as for men and women. Finally, convergent validity analyses found a positive and moderate correlation of PCQ-12 with satisfaction with life and subjective happiness, as well as a negative and moderate correlation with perceived stress and depression.
Non-linear water waves generated by impulsive motion of submerged obstacles

Abstract. A fully non-linear problem on unsteady water waves generated by an impulsively moving obstacle is studied analytically. Our method involves reduction of the Euler equations to the integral-differential system for the wave elevation together with normal and tangential fluid velocities at a free surface. Exact model equations are derived in explicit form in a case where an isolated obstacle is presented by a totally submerged elliptic cylinder. A small-time asymptotic solution is constructed for a cylinder which starts with constant acceleration from rest. It is demonstrated that the leading-order solution terms describe several wave regimes such as the formation of non-stationary splash jets by vertical rising or vertical submersion of the obstacle; the generation of diverging waves is also observed.
Haze types in Beijing and the influence of agricultural biomass burning

Abstract. Emissions from agricultural biomass burning (ABB) in northern China have a significant impact on the regional and global climate. The monthly average aerosol optical depth (AOD) at 550 nm in northern China in 2007 had a maximum of 0.7 in June. The AOD measurements are consistent with regional brown hazes that occurred at that time, which was a period of severe aerosol pollution. Aerosol particles were collected in urban Beijing from 12 to 30 June 2007, during a period of high haze, and studied using transmission electron microscopy with energy-dispersive X-ray spectrometry. The dominant particle types collected in the fine fraction (diameter
Nonlocal Trigger-Target Relations

This article argues that an approach to unbounded harmony that enforces restrictions only over adjacent elements undergenerates for patterns with nonlocal trigger-target relations. Such patterns may occur even in cases where assimilation propagates locally, as found in Baiyina Oroqen and Mọ̀bà Yorùbá. However, a harmony im(perative that is not restricted to adjacent elements is capable of producing these systems, in which a trigger may be related to both adjacent and nonadjacent targets. The appropriate one-to-many relational structure is compatible with Optimality Theory, where well-formedness is evaluated over the entire candidate at once, but it is not consistent with a local iterative spreading rule or an approach using a local spreading constraint, lacking additional constraints on nonlocal dependencies. This study thus identifies a previously unrecognized advantage of analyzing harmony within Optimality Theory, and it signals the necessity for any theory of harmony to handle nonlocal trigger-target relations.
Mediating Role of Relationship Quality in Online Services

This paper is the first to examine the mediating role of relationship quality in the online context. By investigating this major tenet of customer relationship management theory in this nascent service setting, this paper clarifies the interaction between service quality and relationship quality, as they impact on customer loyalty. The findings reveal some fundamental differences in the way that strong relationships and loyalty develop in the online setting vis-à-vis the offline setting. The findings of this empirical research support the existence of a partial mediating relationship. While effective service delivery was found to enhance the quality of customer-firm relationships, and consequently, the customer's perceived loyalty to their main financial institution; there was also evidence of a concurrent link between service quality and loyalty. This finding suggests that a strong relationship does not make customers immune to poor future services, and that firms operating in the online environment should maintain high service standards if they are to enjoy continued loyalty from their customers.
Subjective Questions to Measure Welfare and Well-being

This paper provides arguments in favor of using subjective questions as a proxy to measure welfare and well-being. This approach makes it possible to avoid having to define welfare and well-being means and having to identify the relevant indicators. Instead, individuals themselves define their level of welfare and well-being. For a meaningful analysis of subjective questions, two main assumptions are needed: namely, that individuals are able to evaluate their own situation, and that responses among individuals can be compared. Both assumptions are discussed here. Next, empirical studies that use subjective questions are surveyed. This offers a fIrst approximation of the structure of individual well-being and preferences. Finally, four areas of application are identified, along with a short survey of relevant studies.
ASSESSMENT OF HEAVY METALS IN SURFACE WATER OF THE IKPOBA RESERVOIR, BENIN CITY, NIGERIA.

The present study was carried out to determine the impact of some heavy metals namely, Cd, Mn, Cu, Fe, Pb, Ni, Zn and Cr on the water quality of the Ikpoba reservoir Benin City, Nigeria, with a view to safeguard public health. Water samples were randomly collected from four stations within the Reservoir from August 2005 to December 2005 and were analyzed for heavy metal concentrations using Atomic Absorption Spectrometric technique. The mean concentration of these metals were, Cd, (0.02mg/l), Mn(0.026mg/l), Cu(0.24mg/l), Fe(5.60mg/l), Pb(0.07mg/l), Ni(0.03mg/l), Zn(116.59mg/l) and Cr(0.033mg/l). The mean concentrations of Cd, Fe, Pb, Ni and Zn, exceeded the World Health Organization (WHO) maximum permissible level for drinking water. Keywords: water quality, heavy metals, Ikpoba reservoir
With a Little Help from Our Colleagues: A Longitudinal Study of Social Networks for Innovation

In this paper we investigate the dynamics of networks of employees in the front end of the new product development process. So far, the literature has focused on network structure and has argued that sparse (low density) networks of weak ties are optimal for idea generation. In this paper we include both network structure and network content, and we emphasize the importance of strong ties, density, range, seniority and decision-maker involvement in specific phases of the front end in an environment of uncertainty, ambiguity and tacit knowledge. To test our assumptions, we mapped the full networks of 17 ideas for new product development projects over time in a longitudinal study in two research laboratories. For specific phases of the front end, we found confirmation of our expectations. In addition, it appeared that particularly strong ties between different units advance the adoption chances of ideas. The managerial implication of this latter finding is that communication with good acquaintances or friends in other units should be promoted in the front end of idea generation.
ENHANCEMENT OF RECYCLED AGGREGATE CONCRETE PROPERTIES BY A NEW TREATMENT METHOD

Recently, decreasing natural sources of aggregate accompanied by increasing large quantities of construction and demolition waste (CDW) cause challenges for environment and construction industry. A significant solution for this is to recycle CDW as a new aggregate source for concrete. However, using recycled concrete aggregate (RCA) in concrete involves various obstacles and controversial issues in controlling the quality of recycled aggregate concrete (RAC). This study is an effort to improve the quality of RAC containing 100% coarse RCA by using pozzolanic and sodium silicate solution as new treatment solutions. This study examined performance abilities of RAC after being treated with new treatment solutions and a new mixing procedure. The mechanical properties of RAC were evaluated based on testing of concrete under various conditions. The significant results indicated that sodium silicate combined with pozzolanic materials can improve mechanical properties of RAC containing 100% coarse RCA. At 20% concentration of sodium silicate and silica fume, the compressive strength of RAC could improve up to 36%. Achievements of this approach demonstrated its effectiveness in enhancing the strength of RAC, which is potentially applied to treating RCA for concrete in the future.
An Investigation of the Effects of Emotional Experience Induction on Mirror Neurons System Activity with Regard to Spectrum of Depressive Symptoms

The aim of the present study was to assess the effect of emotional experience induction in the mirror neurons systems (MNS) activity with regard to the spectrum of depressive symptoms. For this purpose, at first stage, 449 students of Kharazmi University of Tehran were selected randomly and completed the second version of the Beck Depression Inventory (BDI-II). Then, 36 students with standard Z-score equal or above +1.5 and equal or equal or below 1.5 were selected to construct two groups of high and low spectrum of depressive symptoms. In the next stage, the basic activity of MNS was recorded (mu wave) before presenting the positive and negative emotional video clips by Electroencephalography (EEG) technique. The findings related to emotion induction (neutral, negative and positive emotion) demonstrated that the activity of recorded mirror neuron areas had a significant difference between the depressive and non-depressive groups. These findings suggest that probably processing of negative emotions in depressive individuals is due to the idea that the mirror neurons in motor cortex matched up the activity of cognitive regions with the person’s schema. Considering the results of the present study, it could be said that the MNS provides a substrate where emotional disorders can be studied and evaluated. Keywords—Emotional experiences, mirror neurons, depressive symptoms.
Discrimination of maize inbreds for kernel quality traits and fatty acid composition by a multivariate technique - doi: 10.4025/actasciagron.v33i4.11031

Quality is considered to be mainly related to protein and oil concentration in maize kernel. Great effort has been made through the elevation of oil and protein concentrations; however, studies to enhance the composition quality of oil have been limited. Maize genotypes with special fatty acid composition may confer different end uses and added value. We investigated eight maize inbreds for kernel quality and fatty acid composition. Kernel samples from a two-year experiment were analyzed for oil, protein, moisture and ash, as well as several fatty acids, including oleic, linoleic, and linolenic acids. Results indicated differences among the genotypes for all traits, except for behenic acid. A680 appeared to be a promising parent to elevate oleic acid, while N194 and RSSSC were the genotypes with the highest oil and protein levels, respectively. A new statistical approach, Canonical Discriminant Analysis with Hypothesis-Error plot technique was utilized to evaluate the data. It showed a good level of agreement with linear tests, and show similar results with those of multi comparison test. With the easily understandable graphical outputs that can interpret the interaction of variables and cases, it offers a good alternative way in analyzing data.
Does proactive personality matter in mobile learning

Increasing attention has been paid to mobile learning studies. However, there is still a dearth of studies investigating the moderating effect of proactive personality on mobile learning achievements. Accordingly, the primary purpose of this study is not only to investigate the key elements that could improve the effectiveness and efficiency of mobile learning, but also to examine the moderating role of proactive personality in mobile learning outcomes. The findings indicate that continuance intention will have a positive influence on mobile learning performance, whereas perceived playfulness will have a limited influence on mobile learning outcomes. Moreover, perceived flexibility advantages will positively affect mobile learning continuance intention and perceived playfulness. With respect to the role of perceived usefulness in perceived playfulness, the results indicate that although perceived usefulness has a positive influence on continuance intention, it has a limited impact on perceived playfulness. Finally, the results indicate that proactive personality plays a moderating role in the relationship between perceived playfulness and mobile learning performance, the connection between perceived flexibility advantages and mobile learning continuance intention, the nexus between perceived usefulness and mobile learning continuance intention, as well as the connection between perceived usefulness and playfulness.
Measurement of antiproton production in p-He collisions and prospects for other inputs to cosmic rays physics from the fixed target program of the LHCb experiment

The LHCb experiment has the unique possibility, among the LHC experiments, to be operated in fixed target mode, using its internal gas target SMOG. The energy scale achievable at the LHC and the excellent detector capabilities for vertexing, tracking and particle identification allow a wealth of measurements of great interest for cosmic ray physics. We present the first measurement of antiproton production in proton-helium collisions at $\sqrt{s_{NN}} = 110$ GeV, which allows to improve the accuracy of the prediction for secondary antiproton production in cosmic rays. Prospects for other measurements achievable in the fixed target program are also discussed.
Quality of Atlantic Cod Frozen in Cell Alive System, Air-Blast, and Cold Storage Freezers

ABSTRACT Gutted Atlantic cod, packed in cartons, were frozen immediately after killing in a magnetic field (cell alive system). The results were compared with traditional air-blast freezing or by putting the cartons directly in a cold storage room (without forced convection of air). After frozen storage, external and fillet properties were compared. In spite of differences in freezing rates, only minor differences were found among treatments. The mechanism for the freezing of fish in the magnetic field, under the current conditions, appeared to be similar to that of traditional freezing methods.
Improving Understanding of Microclimate Heterogeneity within a Contemporary Plant Growth Facility to Advance Climate Control and Plant Productivity

Greenhouse crop production is maximized by maintaining optimal growing conditions. Accurate management of climate conditioning equipment based on measurements of the internal greenhouse microclimate is necessary to optimize crop production. Traditionally, greenhouse microclimate is monitored by a single suite of sensors located at a fixed (often central) location that is considered representative of the entire greenhouse climate. To advance greenhouse crop production additional sensors may better represent greenhouse microclimate heterogeneity and improve performance of climate conditioning equipment. However, elucidating the proper number and distribution of additional sensors requires investigation. Distributed high resolution air temperature (n = 63), relative humidity (n=63), and incoming solar radiation data were collected between May 9th, 2012 and September 5th, 2012 to test the efficacy of conventional centrally located sensors to characterize the spatial and temporal climate variability inside three contemporary greenhouse facilities. Results indicate substantial microclimate heterogeneity with mean horizontal temperature gradients of as much as 5.0°C/m, and mean horizontal VPD gradients of 1.5 kPa/m. Most substantially, the maximum vertical temperature gradient was 11.65°C/m. Results indicate that as few as five properly deployed sensor assemblages (e.g. temperature, humidity, solar radiation) may be necessary to more accurately monitor horizontal and vertical microclimate heterogeneity in a typical greenhouse room. This would improve climate conditioning accuracy and improve the homogeneity of the internal greenhouse climate, which may result in increased productivity and profits for greenhouse managers.
Do U.S. Analysts Improve the Local Information Environment of Cross-Listed Stocks?

We investigate stock return and trading volume reactions to analyst recommendation changes issued by local and foreign analysts for international stocks from 40 countries cross-listed in the U.S. We find that recommendation changes by analysts based in the U.S. lead to significantly higher abnormal returns and lower abnormal volumes in the home market of the cross-listed firm, compared to changes made by local analysts. Our results are strengthened by an identification strategy that relies on analysts who move locations. We do not find evidence that this U.S.-location premium can be explained by a bonding or certification role of U.S. analysts.
Genetic variation and population structure of willowy flounder Tanakius kitaharai collected from Aomori, Ibaraki and Niigata in Northern Japan

The first hypervariable region (HVR-1) of the mitochondrial DNA control region was utilized for determination of genetic variation and population structure in willowy flounder (Tanakius kitaharai) collected from Aomori, Ibaraki and Niigata. A total of 35 haplotypes were detected among 66 individuals with a total of 30 variable sites out of 387 bp sequenced. Average sequence differences between populations (1.0 - 1.1%) were comparable to those within populations (0.9 - 1.2%), suggesting no genetic heterogeneity among samples. The pattern of distribution of genetic variability with high level of haplotype diversity (h = 0.94) and moderate nucleotide diversity ( = 1.0%) was also detected in the HVR-1 region of the mitochondrial DNA control region. AMOVA tests and the conventional population st comparisons revealed no significant genetic structure among the populations. Partitioning populations into coherent geographic groups divided willowy flounder samples (ct = -0.007, P > 0.05) into two major groups: a Sea of Japan group composed of Aomori and Niigata populations; a Pacific Ocean group composed of Ibaraki populations. The minimum spanning tree constructed with 35 haplotypes showed four low-divergent clades, corresponding to those defined in the NJ tree. However, these clades did not appear to have geographic structure. Altogether, the results indicate that willowy flounder is panmictic throughout the examined range in Aomori, Ibaraki and Niigata.
