A comparative study between self-piercing riveting and resistance spot welding of aluminium sheets for the automotive industry

The increased application of lightweight materials, such as aluminium has initiated many investigations into new joining techniques for aluminium alloys. The Resistance Spot Welding (RSW) concept for aluminium has always attracted many researchers from different organizations. Selfpiercing riveting (SPR) is the major production process used to join aluminium sheet body structures for the automotive industry. The research team at the University Of Warwick has investigated these two major joining technologies for aluminium assembly. The paper reported here gives an in depth comparison of the mechanical behavior for each joint type under different loading conditions. It covers symmetrical and asymmetrical assembly from thin gauge of 1.0mm to thick gauge of 3.0mm. The results suggest that generally RSW can provide similar strength performance to SPR with the exception of T-peel; the energy to maximum load needs be considered ‘case to case’ and is dependent largely on loading conditions and the failure mode particularly with respect to SPR. The spread of results for SPR is generally smaller than RSW, and the performance of SPR joints improves as the thickness increases.
Bunch frequency multiplication in the CLIC Test Facility CTF3

The aim of the CLIC Test Facility CTF3 at CERN is to prove the feasibility of key issues of the two-beam based Compact Linear Collider (CLIC) study. In particular, it addresses the generation of a drive beam with the appropriate time structure to produce high power RF pulses at a frequency of 30 GHz. The first major goal of CTF3 was to demonstrate, at low charge, the combination of successive bunch trains by RF deflectors in an isochronous ring. This bunch frequency multiplication has been successfully performed for various combination factors up to five and will be presented.
Characterization of stx2 and its variants in Escherichia coli O157:H7 isolated from patients and animals

In this study, we investigated 72 Escherichia coli O157:H7 strains from humans and animals to determine stx2 and its variants by polymerase chain reaction (PCR) and PCR-restriction fragment length polymorphism. Most isolates were found to carrystx2 or its variants and the stx2c was the dominant subtype; for the prevalence ofstx2c in stx2-positive isolates was 89.6% (42/47). All stx2 and stx2c harboring isolates obtained from humans had caused diarrhea or hemolytic-uremic syndrome. Three strains isolated from a piglet and two cattle carried the stx2c gene with an IS1203v inserted sequence. Sequencing of this region revealed that, this 1.3 kb insertion was very similar to a previously identified IS 1203v sequence and the insertion interrupted the carboxyl end of the B subunit coding region of stx2c gene. The corresponding positions in the stx2c gene sequence in which the IS 1203v sequence was inserted was varied. The isolates possessing IS1203v were inactive in the Vero cell toxicity assay. Key words: Shiga toxin-producing Escherichia coli; stx2; PCR-RFLP; insertion sequence; cytotoxicity.
In vitro comparative toxicity of different insecticides against adults of seven spotted beetle, Coccinella septempunctata L. (Coleoptera: Coccinellidae)

Under the laboratory conditions (28 C±1, 70 ± 5%% relative humidity) a trial was conducted in the laboratory of Department of Entomology, University of Agriculture Faisalabad during 2012-13 to evaluate the effect of comparative toxicity of different insecticides against adults of the ladybird beetle (Coccinella septempunctata L.). In this experiment seven treatments used namely Ememectin Benzoate (Timer® 1.9 EC), Indoxacarb (Steward® 150 EC), Imidachloprid (Crown® 70 WS), Chlorpyrifos (Helmat® 40 EC), Spinosad (Tracer® 480 SC), Leufenoron (Track® 10 EC) and Acetamaprid (Astarp® 250 WP). The experiment was laid out with five replications under Completely Randomized Design (CRD). Leaf dip bioassay method was used for Coccinella septempunctata L. Probit analysis was applied for statistical analysis. Our Results showed that the most toxic chemical was Chlorpyrifos that caused 100% mortality of adults of ladybird beetle after 72 hours and imidachloprid was the safest insecticide which can be included in integrated pest management practices. The order of toxicity on the basis of mortality was Chlorpyrifos > Indoxacarb > Spinosad > Acetamaprid > Ememectin Benzoate > Leufenoron > Imidachloprid.
A structural equation model for evaluating user’s intention to adopt internet banking and intention to recommend technology

Although several prior research projects have focused on the factors that impact on the adoption of information technology, there are limited empirical research works that simultaneously capture technology factors (UTAUT2) and customer specific factors (perceived technology security and intention to recommend) helping users adopt internet banking. Thus, the current study aims to develop an integrated technology adoption model with extended UTAUT model and perceived technology security to predict and explain user’s intention to adopt internet banking and intention to recommend internet banking in social networks. A quantitative approach based survey was conducted to collect the data from 398 internet banking users. For statistical analysis, structural equation model (SEM) approach was used. Convergence and divergence with earlier findings were found, confirming that performance expectancy, effort expectancy, social influence, hedonic motivation and perceived technology security had significant influence on user’s intention to adopt internet banking. Additionally, IPMA analysis show that among all constructs hedonic motivation and perceived technology security had the highest impact on user’s intention to adopt internet banking. For researcher, this study provides a basis for further refinement of technology adoption model while for practitioner improving security factor (perceived technology security) may turn users towards adoption of internet banking.
Antinutritional factors, metabolizable energy and chemical composition of rice bran

Rice bran (RB) samples from the United Kingdom (UK) and Malaysia were analysed for their metabolizable energy (ME), proximate values, mineral contents, amino acid profiles and activities of antinutritional factors, namely lectin (haemagglutinin) and trypsin inhibitor (TI). The lectin activity in the fullfat RB had its greatest haemagglutinating effect on human type B erythrocytes. Defatted RB had no agglutination in any of the blood types tested. In the UK, autoclaving of RB for 5–20 min at 15 psi (121 °C) reduced the lectin and TI activities to 12–25% and 7–10% of its original values respectively, as compared with the activity in the raw forms. However, in Malaysia, autoclaving of RB sampels for 20 min totally destroyed the activity of TI and suppressed their lectin activity to about one half of its original activity. The mean proximate values of
Application of a Biosurfactant Produced in Low-cost Substrates in the Removal of Hydrophobic Contaminants

This work describes the environmental application of a biosurfactant produced from Pseudomonas sp. cultivated in a mineral medium formulated with low-cost substrates. Fermentations were conducted in the mineral medium supplemented with 3 % corn steep liquor and 3 % molasses at 28 oC during 144 h under 200 rpm. The medium surface tension was reduced to 29 mN/m. A Critical Micelle Concentration (CMC) of 0.5 % was obtained from the isolated biosurfactant. The application of the biosurfactant demonstrated an ability to remove 80.0 % of motor oil adsorbed on beaker surfaces. Stone washing tests showed 48.0 % removal at 0.5 % biosurfactant concentration and testing for oil removal in soil results showed around 63.0 % for the removal of motor oil adsorbed on fresh sand. The results obtained with the biosurfactant produced by Pseudomonas sp. , under the conditions tested above show the promising properties of this biomolecule for use in bioremediation of hydrophobic compounds in soils and waters.

How plume‐ridge interaction shapes the crustal thickness pattern of the Réunion hotspot track

The Réunion mantle plume has shaped a large area of the Earth's surface over the past 65 million years: from the Deccan Traps in India along the hotspot track comprising the island chains of the Laccadives, Maldives, and Chagos Bank on the Indian plate and the Mascarene Plateau on the African plate up to the currently active volcanism at La Réunion Island. This study addresses the question how the Réunion plume, especially in interaction with the Central Indian Ridge, created the complex crustal thickness pattern of the hotspot track. For this purpose, the mantle convection code ASPECT was used to design three‐dimensional numerical models, which consider the specific location of the plume underneath moving plates and surrounded by large‐scale mantle flow. The results show the crustal thickness pattern produced by the plume, which altogether agrees well with topographic maps. Especially two features are consistently reproduced by the models: the distinctive gap in the hotspot track between the Maldives and Chagos is created by the combination of the ridge geometry and plume‐ridge interaction; and the Rodrigues Ridge, a narrow crustal structure which connects the hotspot track and the Central Indian Ridge, appears as the surface expression of a long‐distance sublithospheric flow channel. This study therefore provides further insight how small‐scale surface features are generated by the complex interplay between mantle and lithospheric processes.
Phenotypic and genotypic characterization of Staphylococcus aureus isolates recovered from bovine milk in central highlands of Ethiopia

Antimicrobial resistance is becoming an extremely serious global problem. The goal of this study was to determine the prevalence and phenotypic and genotypic characteristics of Staphylococcus aureus isolated from milk and milk product samples in Ethiopia and also to determine the presence of methicillin resistant Staphylococcus aureus (MRSA). A total of 577 milk and milk product samples were collected from central Ethiopia and Staphylococcus spp. were isolated using the method described in FDA Bacteriological Analytical Manual (BAM). Resistance of S. aureus isolates to 12 antimicrobials was determined by using the Kirby-Bauer disk diffusion method. PCR detection of mecA and nuc gene was also conducted. To determine the clonal relatedness of S. aureus isolates, DNA fingerprinting of selected isolates was performed by PFGE. Of the 577 milk and milk product samples investigated, S. aureus isolates were recovered from 120 (21%) of the sample. In addition, coagulase negative Staphylococcus species were also isolated from 361/577 (63%) of the samples. The highest frequency of resistance was observed for penicillin (83%) and the lowest was noted for amoxicillin/clavulanic acid (3%) and gentamicin (3%). Fourteen (14) isolates (13%) recovered from raw milk were found to be susceptible to all the tested antimicrobials while 57% of the isolates were resistant to more than one of the antimicrobials. All the isolates were susceptible to vancomycin and none were found to be methicillin resistant S. aureus based on mecA gene carriage. PFGE analysis of 39 S. aureus isolates identified three separate clonal clusters and also several sporadic isolates. S. aureus isolates in this study were found to be resistant to multiple antimicrobials. This warrants a larger representative study to fully understand the extent of the problem and design better strategies for regulation of antimicrobial use in both the medical and veterinary sectors in central Ethiopia. Key words: Bovine milk, Ethiopia, genotypic resistance, Staphylococcus aureus.
Testing baryon-induced core formation in $\Lambda$CDM: A comparison of the DC14 and coreNFW dark matter halo models on galaxy rotation curves

Recent cosmological hydrodynamical simulations suggest that baryonic processes, and in particular supernova feedback after bursts of star formation, can alter the structure of dark matter haloes and transform primordial cusps into shallower cores. To assess whether this mechanism offers a solution to the cusp-core controversy, simulated haloes must be compared to real dark matter haloes inferred from galaxy rotation curves. For this purpose, two new dark matter density profiles were recently derived from simulations of galaxies in complementary mass ranges: the DC14 halo ($10^{10} < M_{\text{halo}}/M_{\odot} < 8 \times 10^{11}$) and the coreNFW halo ($10^{7} < M_{\text{halo}}/M_{\odot} < 10^{9}$). Both models have individually been found to give good fits to observed rotation curves. For the DC14 model, however, the agreement of the predicted halo properties with cosmological scaling relations was confirmed by one study, but strongly refuted by another. A next question is whether the two models converge to the same solution in the mass range where both should be appropriate. To investigate this, we tested the DC14 and cNFW halo models on the rotation curves of a selection of galaxies with halo masses in the range $4 \times 10^{9}$ - $7 \times 10^{10}$ $M_{\odot}$. We further applied the DC14 model to a set of rotation curves at higher halo masses, up to $9 \times 10^{11}$ $M_{\odot}$, to verify the agreement with the cosmological scaling relations. We find that both models are generally able to reproduce the observed rotation curves, in line with earlier results, and the predicted dark matter haloes are consistent with the cosmological $c-M_{\text{halo}}$ and $M_{*}-M_{\text{halo}}$ relations. The DC14 and cNFW models are also in fairly good agreement with each other, even though DC14 tends to predict slightly less extended cores and somewhat more concentrated haloes than cNFW.
Isolation and characterization of a moderately thermophilic anaerobic alkaliphile, Clostridium paradoxum sp. nov.

Alkaliphilic, moderately thermophilic anaerobic bacteria able to grow above pH 10.5 and 55°C were isolated from various sewage plants in the United States. The strains were motile with two to six peritrichous flagella and formed round to slightly oval terminal spores in terminally distended and slightly enlarged cells. Sporulated cells remained motile. The pH range for growth was between 7.0 and 11.1, with an optimum of around 10.1 At pH 10.1 the temperature range for growth was between 30 and 63°C, with an optimum of 56°C. The shortest observed doubling time (glucose) was around 16 min at 56°C and pH 10.1. No dissimilatory sulfate reduction was detected. The organism utilized glucose, fructose, sucrose, maltose, and pyruvate but required yeast extract or tryptone for growth. Optimal NaCI concentrations for growth were between 50 and 200 mM. The guanine-plus-cytosine content was 30.0 ± 0.10 mol%. On the basis of unique properties and 16S rRNA analysis, the strains are placed in a new species, Clostridium paradoxum, referring to the unusual retainment of motility by sporulated cells. Strain JW-YL-7 (DSM 7308) is designated as the type strain.
PREVALENCE OF SUBCLINICAL MASTITIS AT BANARIPARA UPAZILLA

A study was aimed to determine the prevalence of sub-clinical mastitis and also determine the other risk factors that intensify this condition. Prescribed questionnaire was used to take baseline information of the animals and farms and California mastitis test kit was used to determine the SCM in lactating cow at farm level. It appears from this study that an overall prevalence of SCM was 51.56% in milking cows at Banaripara Upazilla, Barisal. Crossbred cows were significantly affected with SCM than local breed lactating cows. The farm type affect significantly (p<0.05) on the occurrence of this diseases. The prevalence of sub-clinical mastitis in cow was significantly (p<0.05) higher in 3 rd (80%) parity compared to 1 (38.09%) and 2 (45.83%) parity as well as non pregnant cows (55.55%) are more prone to infection than pregnant cow (46.43%). The farm floor condition and aged cows don’t have any effect on SCM. Prevalence of sub-clinical mastitis was significantly (p<0.05) higher in high yielding (87.5%) cows than medium (70%) to low (33.33%) yielding cows. A well documented continued research and educational effort is required to increase producer awareness of cost due to mastitis to the dairy enterprise. From this study it was concluded that cow breed, farm type, parity of cows, physiological status of animal and milk yield per cow were found to be important risk factors associated with the occurrence of sub clinical mastitis in dairy cows. The occurrence of this disease remains a substantial problem for dairy producers.
Black Hole Mass Scaling Relations for Spiral Galaxies. II. MBH–M*,tot and MBH–M*,disk

Black hole mass (MBH) scaling relations are typically derived using the properties of a galaxy’s bulge and samples dominated by (high-mass) early-type galaxies. Studying late-type galaxies should provide greater insight into the mutual growth of black holes and galaxies in more gas-rich environments. We have used 40 spiral galaxies to establish how MBH scales with both the total stellar mass ( M * , tot ) and the disk’s stellar mass, having measured the spheroid (bulge) stellar mass ( M * , sph ) and presented the MBH– M * , sph relation in Paper I. The relation involving M * , tot may be beneficial for estimating MBH either from pipeline data or at higher redshift, conditions that are not ideal for the accurate isolation of the bulge. A symmetric Bayesian analysis finds log ( M BH / M ⊙ ) = ( 3.05 − 0.49 + 0.57 ) log { M * , tot / [ υ ( 6.37 × 10 10 M ⊙ ) ] } + ( 7.25 − 0.14 + 0.13 ) . The scatter from the regression of MBH on M * , tot is 0.66 dex; compare 0.56 dex for MBH on M * , sph and 0.57 dex for MBH on σ*. The slope is >2 times that obtained using core-Sérsic early-type galaxies, echoing a similar result involving M * , sph , and supporting a varied growth mechanism among different morphological types. This steeper relation has consequences for galaxy/black hole formation theories, simulations, and predicting black hole masses. We caution that (i) an MBH– M * , tot relation built from a mixture of early- and late-type galaxies will find an arbitrary slope of approximately 1–3, with no physical meaning beyond one’s sample selection, and (ii) evolutionary studies of the MBH– M * , tot relation need to be mindful of the galaxy types included at each epoch. We additionally update the M * , tot –(face-on spiral arm pitch angle) relation.
Research on Teacher Self-efficacy in Turkey: 2000-2017

In this study, 48 empirical studies on teacher self-efficacy published between 2000-2017 were reviewed in terms ofcertain basic characteristics, and the research trends were revealed in this area. According to the results obtained inthe review, teacher self-efficacy studies in the Turkish context showed an increase in the course of time. Teacherself-efficacy in a specific area was observed to be frequently examined within the context of teaching a subject orusing technology in education. This increase in the number of studies did not reflect much on the diversity of theresearch methods employed, and the studies were often conducted by using quantitative methods. Elementary andmiddle schools were mostly chosen as the research context. Furthermore, the amount of research on threeself-efficacy areas (i.e. collective teacher efficacy, teacher self-efficacy sources, and teachers’ general self-efficacy)were considerably limited. Moreover, none of the studies examined the relationship between teacher self-efficacyand collective teacher efficacy and student achievement. Common findings of the studies showed that teacherself-efficacy was a strong predictor or a mediator variable. In this sense, researchers are suggested to study howself-efficacy can be developed experimental and longitudinal works and to conduct studies to reveal insights aboutcollective efficacy in schools, teachers’ general self-efficacy, and the outcomes of these efficacy characteristics.
Conflict Resolution in the Culturally Diverse Workplace: Some Data from Hong Kong Employees

L’objectif de la presente recherche etait l’etude de la facon dont la distance sociale percue par des salaries de Hong Kong affecte leurs attributions et perceptions d’une situation de conflit, ainsi que leurs choix des procedures de resolution du conflit. 122 autochtones ayant affirme avoir des contacts interculturels dans le cadre de leur emploi ont lu un scenario decrivant une discussion professionnelle impliquant un salarie local et un superieur qui etait de Hong Kong, des Etats-Unis ou de Chine continentale. On leur demandait alors d’imaginer qu’ils etaient l’employe local et de remplir un questionnaire concu pour evaluer les dimensions sus-mentionnees. La mesure de la distance sociale montre que, comme prevu, ces sujets se sentaient plus proches de leur compatriote que de l’Americain ou du Chinois continental. De plus, la perception de la distance sociale etait liee a cette de la situation, a l’attribution des responsabilites et a la resolution du conflit. On analyse les retombees theoriques et pratiques de ces resultats sur la gestion des conflits interculturels et sur la construction social des categories courantes portant sur la diversite culturelle. The present study was designed to examine how perceived social distance affects Hong Kong employees’ attributions and perceptions of a conflict situation, and their choices of conflict resolution procedures. One hundred and twenty-two local workers who reported having intercultural contacts in their jobs read a scenario of a workplace dispute involving a local employee and a superior who was either from Hong Kong, the US, or Mainland China. They were then asked to imagine that they were the local employee in that situation and to complete a questionnaire that was designed to measure the above constructs. Results of the social distance measure suggest that, as expected, these participants were closest to fellow Hong Kong Chinese, and were more distant with people from the US and Mainland China. In addition, differences in perceived social distance were associated with how they perceived the conflict situation, attributed responsibilities, and resolved the conflict if they were in such a situation. Both theoretical and applied implications of these findings for conflict management in culturally diverse workplaces are discussed, as well as the social construction of commonly used diversity categories.
Dual birth and death processes and orthogonal polynomials

We discuss connections between birth and death processes and orthogonal polynomials. We survey certain spectral properties of orthogonal polynomials and spectra of birth and death processes. Birth and death processes with linear birth and death rates are studied in some detail. We also mention some results concerning birth and death processes whose transition rates are rational functions.
