Risk management for build, operate and transfer (BOT) projects in Kuwait

Successful implementation of build-operate-transfer (BOT), infrastructure projects is dependent on a full and thorough analysis of factors that include social, economic and political, amongst others. Alongside the financially focused evaluations, qualitative factors will also have a strong impact on the project and so require specific techniques for the analysis. This paper presents a new evaluation framework, based on the analytical hierarchy process technique, for use in assessing the most common and significant decision factors relating to risks in BOT projects. Consultations with an expert group identified a series of risk decision factors. The results produced twenty-eight critical Risk Factors, which have a particular impact on the risks of BOT projects. The project risk framework was constructed by classifying the factors into five categories. The framework was successfully validated using a BOT project case study. This research seeks to make a valuable contribution to the field by having developed and validated a new risk evaluation framework, focused on BOT projects in Kuwait.
Spatial distributions of core-collapse supernovae in infrared-bright galaxies

We have measured the correlation between the locations of core-collapse supernovae (CCSNe) and host galaxy light in the Hα line, near ultraviolet (NUV), R-band and Ks-band to constrain the progenitors of CCSNe using pixel statistics. Our sample consists of 86 CCSNe in 57 infrared (IR) -bright galaxies, of which many are starbursts and ten are luminous infrared galaxies (LIRGs). We also analyse the radial distribution of CCSNe in these galaxies, and determine power-law and exponential fits to CCSN surface density profiles. To probe differences between the SN population of these galaxies and normal spiral galaxies, our results were compared to previous similar studies with samples dominated by normal spiral galaxies where possible. We obtained a normalised scale length of 0.23 +0.03 0.02 R25 for the surface density of CCSNe in IR-bright galaxies; less than that derived for CCSNe in a galaxy sample dominated by normal spiral galaxies (0.29 ± 0.01). This reflects a more centrally concentrated population of massive stars in IR-bright galaxies. Furthermore, this centralisation is dominated by a central excess of type Ibc/IIb SNe. This may be due to a top-heavy initial mass function and/or an enhanced close binary fraction in regions of enhanced star formation. Type Ic SNe are most strongly correlated with Hα light and NUV-bright regions, reflecting the shortest lifetime and thus highest mass for type Ic progenitors. Previous studies with samples dominated by normal spiral galaxies have indicated a lower Ibc–Hα correlation than our results do, which may be due to the central excess of type Ibc/IIb SNe in our sample. The difference between types II and Ib is insignificant, suggesting that progenitor mass is not the dominant factor in determining if a SN is of type Ib or II. Similar differences in correlation can be seen in the Ks-band (which in these galaxies is dominated by red supergiants and thus also traces recent star formation), with type Ibc/IIb SNe tracing the Ks-band light better than type II in our sample.
Study of Heterosis and Combining Ability for Yield and its Component Traits in Brassica juncea L.

In Indian subcontinent, B. juncea is the dominant species growing along with B. rapa (syn. B. campestris L.) and B. napus L. and these are the important sources of edible oil in India. Brassica juncea is commonly known as Indian mustard. It is an amphidiploid of B. rapa (2n=20; genome AA) and B. nigra (2n=16; genome BB) having 36 chromosomes and genome AAB Heterosis breeding approach is the most successful technological options being employed for the improvement of crop varieties. Heterosis is the interpretation of increased vigor, manifested by cross bred as compared with corresponding inbreds. Heterosis breeding could be used for enhancing crop productivity in Brassica juncea, a major oilseed crop of the Indian subcontinent. It is an important tool to overcome the existing yield barriers. For developing promising varieties through hybridization a careful choice of parents and breeding methodology are matters of great concern to a plant breeder.
We love to hate them! Social media-based anti-brand communities in professional football

Social media has promoted anti-brand communities, which build around the shared aversion to a specific brand. The purpose of this paper is to investigate social media-based anti-brand communities and their effects on the sports team brand in question. ,The authors conducted a netnographic study of Facebook-based anti-brand communities that oppose a professional football team. ,The netnographic study reveals characteristics and drivers of Facebook-based anti-brand communities that oppose a professional football team. The research further identifies co-destructive behaviours of anti-brand community members that harm the sports team brand and even its sponsors. However, the findings also reveal that anti-brand communities may play a positive role in sport, as they strengthen the relationship between fans of the opposed brand and this brand and foster rivalry among football fans. ,This research establishes the relevance of social media-based anti-brand communities for sports brands. Recommendations are made for team sport brands with regards to how to deal with the phenomenon of anti-brand communities. ,While the previous research on anti-brand activism focused on either offline movements or movements using traditional websites, this research is the first to investigate the pivotal role of social networking sites for anti-brand activism. The paper further uncovers unique motivational, attitudinal, and behavioral patterns of fans that meet in communities opposing not only the rival team, but also the brand associated with the team. Findings show ways to better understand and deal with such anti-brand communities in sports.
Characterization of differentially expressed genes induced by virulent and avirulent Magnaporthe grisea strains in rice

To identify differentially expressed genes of rice induced by virulent and avirulent of pathogen Magnaporthe grisea, an indica rice Zhong156 with race-specific resistance to leaf blast, was used to establish two subtractive cDNA libraries. For this purpose a Suppression Subtractive Hybridization was used after inoculation with an avirulent strain ZC15 and a virulent strain ZB1 of Magnaporthe grise. Then differential screening, sequencing, function annotation and RT-PCR were carried out and 25 cDNA clones showing differential expression (during 72 h of infection) between the avirulent and virulent strains were identified. The expression profile showed that (1) these differentially expressed genes were induced or suppressed after inoculation with the two strains, but the changing trends, degree and time of expression varied in different interactions. These differences were due to the different strains of the pathogen infection; (2) the genes induced or repressed by both strains were considered participating in the fundamental defense responses and (3) genes induced by the avirulent strain which repressed by the virulent strain (or opposite trends) might play a pivotal role in regulating the race-special resistance.
Architectural classes of aquatic food webs based on link distribution

Link distribution is an important architectural feature of ecological networks, since it is thought to influence community dynamics. Several attempts have been made in order to characterize the typical link distribution of food webs, but the number of webs studied thus far is low and their quality is unbalanced. Comparability is a rarely asked methodological question, and as far as we see only two data bases are available which allow reliable comparison of food webs: one for terrestrial, high resolution, host-parasitoid webs and another for highly aggregated, marine trophic networks. We present an analysis of a set of food webs belonging to the latter type, since the host-parasitoid networks are only subgraphs and therefore uninformative on the structure of the entire community. We address the following three questions: (1) how to characterize the link distribution of these small networks which cannot always be fitted statistically to well-known distributions (such as the exponential or the Poisson, etc.), (2) are these distributions of more or less similar shape or they belong to different „architectural classes”, and (3) if there are different classes, then what are their distinctive topological and biological properties. We suggest that link distribution of such small networks can be compared to each other by principal coordinates ordination and clustering. We conclude that (1) the webs can be categorized into two different classes, and (2) one of the classes contains significantly larger and topologically more heterogeneous webs for which net output of material is also of higher variance. We emphasize that link distribution is an interesting and important property not only in case of complex, speciose food webs, but also in highly aggregated, low-resolution webs.
Beyond Migrant Integration Policies: Rethinking the Urban Governance of Migration-Related Diversity

Bringing together literature from public administration and migration studies, this article makes the case for a reconceptualisation of urban governance of migration-related diversity. It shows that Europe is experiencing a transformation towards structurally high levels of mobility (with the recent refugee situation as only the most recent manifestation), contributing to a further increase in the complexity of diversity, i.e., superdiversity. The local level in particular seems to be facing these challenges most concretely. The article therefore calls for a local turn, not only in policies themselves, but also in the study of migration and diversity. Mainstreaming is identified in this article as a promising governance strategy for cities to devote greater structural attention to the issues of diversity and migration. It reflects the generalisation of migration as a phenomenon that influences all policies and institutions in a city, and calls for a generic rather than a specific approach.
Continued disappearance of the benthic amphipod Diporeia spp. in Lake Michigan: is there evidence for food limitation?

Benthic surveys were conducted in the southern basin of Lake Michigan and throughout the lake to assess trends in benthic populations, emphasizing recent changes in densities of the benthic amphipod Diporeia spp. and dreissenid mussels. In the southern basin, Diporeia populations declined 89%, 91%, and 45% between 1993 and 2002 at sites <30, 3150, and 5190 m, respectively. Lakewide, the population declined 65% between 19941995 and 2000. Over the same time period, dreissenid densities, particularly Dreissena bugensis, increased. Intensive studies at 45 m sites in the southeastern region examined changes in lipid content, age structure, and benthic food inputs relative to the hypothesis that food limitation was a factor in Diporeia's disappearance. As Diporeia densities declined to zero, lengthweight remained unchanged, and lipid content generally increased. Recruitment still occurred, but the young did not survive to become adults.

Dynamics Modeling of “CEDRA” Rescue Robot on Uneven Terrains

In this paper an effective approach for kinematic and dynamic modeling of high mobility wheeled mobile robots (WMR) has been presented. As an example of these robots, the method has been applied on CEDRA rescue robot which is a complex, multibody mechanism. The model is derived for 6-DOF motions enabling movement in x, y, z directions, as well as pitch, roll and yaw rotations. Forward kinematics equations are derived using Denavit-Hartenberg method and the wheels Jacobian matrices. Moreover the inverse kinematics of the robot is obtained and solved for the wheel velocities and steering commands in terms of desired velocity, heading and measured link angles. Finally dynamical analysis of the rover has been thoroughly studied. Due to the complexity of this multi-body system especially on rough terrain, Kane’s method of dynamics has been used to model this problem. The approach has been developed in such a way that it can easily be extended to other mechanisms and rovers.Copyright © 2004 by ASME
Peroxidase Activity in Native and Callus Culture of Moringa Oleifera Lam

Manscript received May 13, 2013; revised July 11, 2013. Abstract—In vitro Moringa oleifera Lam. seedlings were successfully produced through seed culture on Murashige & Skoog (MS) agar medium containing 3% (w/v) sucrose and 0.2% (w/v) Gelrite in the absence of growth regulators under 1,500 lux of light density, 16 hour photoperiod light at temperature of 25 ± 2°C. Shoot-derived callus and rootderived callus of M. oleifera were established via culture of shoot and root on the MS medium supplemented with 0.5 mg/l of 2,4-dichlorophenoxy acetic acid (2,4-D) in the dark at 25 ± 2°C. Stem, leaf and root of native M. oleifera and M. oleifera callus were assayed for peroxidase activity using guaiacol as a substrate of the enzyme. In native plant, crude extract from root provided the highest peroxidase specific activity, followed by those from stem and leaf with the specific activity of 19.73 ± 0.18, 16.56 ± 1.43 and 13.38 ± 1.04 unit/mg protein, respectively. Crude extract of root-derived callus and shoot-derived callus of M. oleifera possessed specific activity of 167.25 ± 16.12 and 103.99 ± 10.64 unit/mg protein. These values are significantly higher than their counter parts from native M. oleifera suggesting the potential use of the callus cultures as new and improved sources of peroxidase.
Muscles of the Neck , Trunk and Tail in the Noisy Scrub-bird , Atrichornis clamosus , and Superb Lyrebird , Menura novaehollandiae ( Passeriformes : Atrichornithidae and Menuridae

Muscles of the neck, trunk and tail of the Noisy Scrub-bird, Atrichornis clamosus, are described, illustrated and compared with those of the Superb Lyrebird, Menura novaehollandiae. It is proposed that hypertrophy of various neck muscles in A trich orn is is related to use of the head in penetrating litter and undergrowth. Atrichornis and Menura are shown to have qualitative differences in myology and in morphology of the uropygial glands, but taxonomic interpretation of these differences is judged to be premature without broader comparisons.

Phenology of Protura in a northwestern Italian forest soil (Hexapoda: Protura)

GALLI L. , CAPURRO M. , SHRUBOVYCH J., TORTI C. 2012. Phenology of Protura in a northwestern Italian forest soil (Hexapoda: Protura). Acta zool. cracov. , 55(1): 33-43. Abstract. Protura extracted from soil and litter samples collectedmonthly in aQuercus suber wood (from February 2007 to January 2008) near Bergeggi (Liguria, NW Italy) were studied. Of 786 mounted specimens, 682 were determined to specific level and attributable to 11 species: Proturentomon minimum, Acerentulus confinis, Acerentulus terricola, Gracilentulus gracilis, Acerentomon affine, Acerentomon doderoi, Acerentomon italicum, Acerentomon maius, Acerella tiarnea, Eosentomon noseki and Eosentomon transitorium. A. terricola is a new record for the Italian fauna. Two peaks of Protura abundance were found (March-April and June, respectively); however they were still substantial throughout the winter and spring, while in August and September there was a minimum, probably due to summer drought. Phenology of the dominant species (Acerentulus confinis, Acerentomon italicum, Acerentomon maius, Acerella tiarnea and Eosentomon transitorium) was examined.
Correlation Between Cyclooxygenase-2 Expression and HuR Cytoplasmic Translocation of Breast Cancer

Background : Embryonic lethal abnormal vision (ELAV)-like protein HuR is known to stabilize mRNA through binding AU-rich elements in the 3’-untranslated region. Recent studies show that HuR expression is associated with the expression of several genes including cyclooxygenase-2 (COX-2). HuR exists predominantly in the nucleus, but cytoplasmic translocation of HuR is thought to be more important for its activity. COX-2 is a well-known enzyme that promotes tumor growth. Methods : To evaluate the correlation of HuR and COX-2 expression, we analyzed expression of HuR and COX-2 in 91 cases of breast cancer using immunohistochemistry. Results : Nuclear and cytoplasmic expression of HuR was seen in 76 (83.5%) and 19 (20.9%) of 91 cases respectively. COX-2 immunoreactivity was seen in 54 (59.4%) cases. Cytoplasmic HuR expression showed significant correlation with COX-2 expression (p=0.001). Nuclear HuR showed no correlation with COX-2 expression or other clinicopathological parameters. COX-2 expression is significantly associated with tumor grade (p=0.028). COX-2 (p=0.092) and cytoplasmic (p=0.569) and nuclear HuR (p=0.247) expression showed no correlation with survival. Conclusions : These results suggest that cytoplasmic HuR expression is associated with COX-2 expression in breast cancer and cytoplasmic location of HuR might contribute to the stabilization of COX-2 mRNA.
Dimensional crossover in spin-orbit-coupled semiconductor nanowires with induced superconducting pairing

We show that the topological Majorana modes in nanowires much longer than the superconducting coherence length are adiabatically connected with discrete zero-energy states generically occurring in short nanowires. We demonstrate that these zero-energy crossings can be tuned by an external magnetic field and are protected by the particle-hole symmetry. We study the evolution of the low-energy spectrum and the splitting oscillations as a function of magnetic field, wire length, and chemical potential, manifestly establishing that the low-energy physics of short wires is related to that occurring in long wires. This physics, which represents a hallmark of spinless p-wave superconductivity, can be observed in tunneling conductance measurements.
Why Do They Continue to Use Pesticides? The Case of Tomato Growers in Boushehr Province in Southern Iran

Despite huge environmental, economical, health, and societal costs of pesticides, research has argued that farmers in developing countries will continue to use pesticides. The present study used an extended model of the theory of planned behavior (TPB), which includes the additional variables of moral norm and self-identity, to predict the farmers’ decisions (intentions) regarding pesticides usage in a multistage, clustered random sample of farmers (n= 150) in a face-to- face survey of students that was undertaken in Dyer County in Southern Iran. The reliability and validity of the instruments were examined and approved. Findings revealed that the extended model is an improvement over the standard TPB variables for predicting intention. Hierarchical regression analysis showed that attitude, subjective norm, perceived behavior control and self-identity can predict 63% of variances in farmers’ intentions. In conclusion, the results of this study demonstrated that the extended TPB can be used as a conceptual framework for intervention programs aimed at decreasing pesticides spraying intention.
Fast-spinning Black Holes Inferred from Symmetrically Limb-brightened Radio Jets

This paper theoretically investigates the relations between the structure of relativistic jets and produced synchrotron images, by using a steady, axisymmetric force-free jet model. We especially focus on the limb-brightened jets that are largely symmetric to the jet axes and observed in some active galactic nuclei, such as M87, Mrk 501, Cyg A, and 3C84. We find that symmetrically limb-brightened images can be produced when magnetic field lines of the jet penetrate a fast-spinning black hole (BH), as motivated by the Blandford–Znajek mechanism. On the other hand, jets with magnetic field lines that pass through a slowly spinning BH or the Keplerian accretion disk produce highly asymmetric radio images. In addition, the edge of a counterjet tends to be luminous in the accretion-disk model even for rather small viewing angles, which may be problematic for some observed jets. We also suggest that the site of particle accelerations in relativistic jets can be constrained by fitting the radio images to observations. This kind of study focusing on the jet images far away from the central engine is complementary to those concentrating directly on the innermost region with upcoming data from the Event Horizon Telescope.
Evolution of GaSb epitaxy on GaAs(001)‐c(4×4)

The growth of GaSb films by molecular beam epitaxy on GaAs(001)‐c(4×4) at 490 °C has been studied in situ with scanning tunneling microscopy and ex situ with transmission electron microscopy. As the film is deposited, four distinct growth regimes are observed: the first two monolayers grow layer by layer with platelet‐like two‐dimensional (2D) islands; the next monolayer forms coherently strained three‐dimensional (3D) quantum dots; further deposition induces film relaxation and rough 3D growth; for film thicknesses ≳100 nm the growth is again 2D, proceeding via spiral growth around emerging threading dislocations. The atomic‐scale mechanisms inherent in the transitions between the growth regimes are discussed. Variations in growth procedures aimed at improving the quantum dot uniformity and reducing the dislocation density are proposed.
Attractiveness of Methyl Eugenol–Baited Traps to Oriental Fruit Fly (Diptera: Tephritidae): Effects of Dosage, Placement, and Color

The attractiveness of methyl eugenol-baited traps to the oriental fruit fly, Bactrocera dorsalis (Hendel), was tested under different conditions; i.e., trap place- ment, color, and methyl eugenol dosage. The mean number of flies caught in hanging traps, 1-2 m above the ground (255), was not significantly different from the mean number in uncovered leaf litter traps (264), but was significantly greater than the num- ber of flies in the covered leaf litter traps (85). Hanging and leaf litter traps interfered with each other when placed 2-3 m apart, but not when they were over 10 m apart. The mean numbers of oriental fruit flies caught in traps baited with 0, 2, 10 and 20 drops of methyl eugenol were significantly different, the numbers of flies increasing with in- creasing dose. In color preference studies, the mean number of flies captured in the clear traps was significantly greater than the numbers caught in the yellow, red, blue, or green traps. These results indicate that males have a strong aversion to entering shaded or dark traps. Clear traps placed in exposed sites should improve trap effi- ciency in both control and monitoring programs.
