Decision Making Methodology for the Selection of Gas-liquid Separators

Gas liquid separation is a critical operation in many industries, including the gas and oil industry. In fact, costly equipment like heat exchangers and compressors rely on the good performance of gas scrubbers. In the particular case of Norway, most of these operations are offshore where the plot area is critical. On the other hand, the separation of liquid droplets from the gas stream is generally performed in bulky and heavy pressure vessels. More compact technologies are emerging though. However, it is becoming difficult to select the appropriate separator and it is required engineering experience. Therefore, the objective of this project is to develop mathematical models for selected technologies to facilitate the selection. The technologies selected were the traditional knitted mesh separator and the recent multi-cyclone scrubber. The models provide the basic dimensions, weight, purchase and installed costs for both scrubbers. The results of both models were compared and extrapolated to hypothetical situations to establish when a compact technology becomes competitive. For this comparison, gas load factor and costs per flow rate were used. In fact the vessel compactness is related to the former. Therefore, it is intended to have values much higher than 0.107 m/s corresponding to traditional separators at atmospheric pressure. In fact, a factor slightly higher than 0.14 m/s would make very competitive multi-cyclones; which can be achieved at pressures higher than 70-80 bar. Furthermore, technologies with factors up 0.5 to 1 m/s might be much more attractive. Nevertheless, there would be restrictions in achieving the maximum gas load factor expected.
Hotspot-ridge interaction in the Indian Ocean: constraints from Geosat/ERM altimetry

SUMMARY Upper-mantle structure of Indian Ocean spreading ridges was investigated by track segments of Geosat/ERM altimeter measurements. To determine the upper-mantle structure of the Earth’s gravity field, a low-degree and -order spherical harmonic representation of the geoid was removed. A test of several reference fields suggested that a degree 2-25 field with gradually rolled off coefficients (Sandwell & Renkin 1988) offers an adequate representation of the long-wavelength geoidal undulations. Filtered profiles of three individual ridge segments display a strong asymmetry in geoid versus age trends of conjugated rift flanks. The unusually low geoid slopes on one flank can perhaps best be explained as a dynamic or thermal phenomenon reflecting a flow connection between a neighbouring off-axis hotspot plume and the ridge axis, while the other flank simply cools as it spreads away from the axial zone. It seems reasonable to hypothesize that the Southwest Indian Ridge and the Southeast Indian Ridge act as sinks for plumes beneath Agulhas Plateau and Kerguelen Islands, respectively. The Carlsberg Ridge data suggest that the Rkunion hotspot contaminated northwestern African lithosphere until 15 Ma. Moreover, symmetric flattening of geoid versus age trends of conjugated ridge flanks offers evidence that plume events affect geoid versus age trends

Background: COPD, a progressive, partly reversible condition with airflow limitation particularly warrants the inclusion of pharmacists in the healthcare team. Extreme physician scarcity severely limits the implementation of quality healthcare in India. Pharmacist-led educational intervention achieves smoking cessation and improves medication adherence. Objective: This study evaluated the effectiveness of a clinical pharmacist-led intervention on medication adherence in COPD patients in a teaching hospital. Methods: In an open-labelled randomized controlled study at Kasturba Medical College Hospital, Manipal, India, patients were randomly assigned to two groups (Intervention group [IG] and Control group [CG]), and were matched for socio-demographics and clinical characteristics. Medication adherence was assessed by the Morisky, Green and Levine Medication Adherence Questionnaire (MAQ). In IG, pharmacist intervention placed emphasis on (1) compliance, (2) smoking cessation, (3) exercise, (4) inhaler use and (5) need for timely follow up. The MAQ assessment was repeated at 6, 12, 18 and 24 months. Data were analysed statistically by SPSS version 20.0. Results: Out of 328 patients screened during March 2012 to June 2013, 260 were recruited. Of these, 206 completed the follow-up (98 in CG and 104 in IG). Medication adherence improved significantly after pharmacist intervention in IG at all follow-up time points (P<0.001). It increased from 49% at the baseline to 80% after 24 months (P<0.001). Carelessness about taking medicines was one of the main reasons for non-adherence in COPD patients, but was effectively reduced by the intervention. Conclusions: This is the first randomized controlled trial in India that demonstrates the pivotal role of pharmacist-led educational intervention in improving medication adherence in COPD. Involving non-physician health professionals could be the best strategy, for resource-poor nations like India, because the current physician-centric healthcare has no emphasis on patient education and counseling.
Experience Does not Eliminate Bubbles: Experimental Evidence

We study the role of investor experience in the formation of asset price bubbles. We conduct a call market experiment in which participants trade assets with each other and a learning-to-forecast experiment in which participants only forecast future prices (while trade based on these forecasts is computerized). Each experiment comprises three treatments varying the information that participants receive about the fundamental value. Each experimental market is repeated three times. Throughout, we observe sizable bubbles that persist despite participant experience. Our findings in the call market experiment contrast with those in the literature. Our findings in the learning-to-forecast experiment are novel.
Phase tuning approach for polyharmonic power amplifiers

In this paper, new conditions for achieving the high efficiency and high output power capability of polyharmonic power amplifies are presented. These conditions can be used in future development of new types of polyharmonic amplifiers with similar efficiency and output power capability as those of Class F amplifies. However, a quite difficult tuning of an output network as in class-F amplifiers is not required.
Development of a test setup for exploring the potential of haptic feedback for maritime operations

When human operators control complex machines, haptic feedback on the control interfaces can reduce operator errors and workload and increase situational awareness. Such benefits have been demonstrated during control of vehicles, drones, remote-controlled robots, but the maritime industry has so far largely ignored the potential of haptic feedback on the control interface of vessels. This paper aims to illustrate such potential. First, three vessel control schemes are provided to illustrate similarities and differences in: manual control, supervisory control of an autopilot, and manual control while assisted by haptic feedback. Second, the design of a maritime simulator with active control levers is described, that allows exploration of the potential of haptic feedback for ship propulsion and manoeuvring control. An actuated 2-DOF azimuth control lever was designed, that can not only command engine speed and thruster azimuth angle by providing a position input, but that can also provide haptic feedback by generating force feedback in both degrees of freedom. Two such levers were constructed and were programmed to communicate with a commercial ship simulation environment, in which a scenario of a harbour tug navigating towards the next waypoint was programmed. A haptics software module was designed to allow easy programming of various types of assistive haptic feedback: virtual hard stops, damping fields, vibrations and repulsive or attractive forces. A real-time visualisation of the operation and the relevant signals is presented on multiple computer screens. Third, this paper describes the implementation of three different types of haptic feedback to support navigation towards a waypoint: vibrations when heading errors exceed a certain boundary; repulsive forces that assist in steering away from certain boundaries; and assistive forces to guide towards a waypoint. It is concluded that the developed maritime haptic simulator allows for human-in-the-loop experiments to explore potential benefits of haptic feedback for maritime applications: we could stably and reliably implement various force feedback designs based on task-related information from the simulated environment. This work also paves the way for developing operator support systems for other, more complex tug operations, as well as support for remote control of (semi-)autonomous ships.
Effects of Glutamine on Growth Performance, Intestinal Morphology and Intestinal Barrier Function of Broilers

The effect of glutamine (Gln) on growth performance, intestinal morphology and intestinal barrier function were evaluated in broilers. A total of 320 birds were divided into a control group (CON) and three experimental groups (Gln 1, Gln 2 and Gln 3). Broilers of group CON received basal diet; broilers in group Gln 1, Gln 2 and Gln 3 were supplemented with 0.5%, 1.0% and 1.5 % Gln, respectively, for 42 days. The results indicated that Gln has no influence on the average daily gain (ADG) among the treatments in the periods of 1 to 21 d, 22 to 42 d and 1 to 42 d (P > 0.05). However, Gln improved average daily feed intake (ADFI) and feed intake: average daily gain (F: G), increased the villus height, villus height to crypt depth ratio (V/C) and the activities of sucrose, the ZO1, claudin-1 and occluding mRNA expression levels (P 0.05). Moreover, Gln decreased the crypt depth of jejunum and ileum in broilers at days 21 and 42 (P 0.05). In conclusion, Gln had a positive effect on growth performance and gut parameters by modifying the function of the intestinal mucosa barrier.
Labor-market status and first-time parenthood: The experience of female minorities in the United States, 1979-2012

Background. The United States has been a diverse country since it is establishment. The effects of socioeconomic characteristics including immigration, age, employment status, educational attainment on total fertility rate have been discussed in the previous studies. Objective. The objectives in this study are to explore whether the difference in the timings of first childbirth among Hispanic women, Black women, and Non-Hispanic, Non- Black women exist in the United States and what factors affect the timings of first childbirth by means of exploiting the National Longitudinal Survey. Design. The National Longitudinal Survey 1979 is used as the dataset in the study. 5276 female respondents, whose age is from 17 to 22 years old, participated in the survey. The Cox Proportional Hazard Model estimates the risk of first childbirth among various races by 2012. The effects of ethnicity and educational attainment on the timing of first birth are calculated using an interaction regression. Results. The female employment exerts negative impacts on the timing of first childbirth. The extent to which the female employment prevents parenthood is different among various ethnicities. The risk of first childbirth in female minority with higher education is not different with that in Non-Hispanic/Non-Black women. The risk of first childbirth in single women is the lowest. (Less)
Less-Java , More Learning : Language Design for Introductory Programming

We present Less-Java, a new procedural programming language with a simple and concise syntax, implicit but strong typing via type inference, and built-in unit testing. These features make programming in Less-Java more intuitive for novice programmers than programming in traditional introductory languages. This will allow professors to dedicate more class time to fundamental programming concepts rather than syntax and language-specific quirks.
Ultrathin limit and dead-layer effects in local polarization switching of BiFeO3

Using piezoresponse force microscopy in an ultrahigh vacuum, polarization switching has been detected and quantified in epitaxial BiFeO3 films from 200 to about 4 unit cells thick. Local remnant piezoresponse was utilized to probe both ferroelectric properties and effects of imperfect electrical contacts. It was found that the shape of electromechanical hysteresis loops is strongly influenced by an extrinsic dielectric gap, primarily through the suppressing effect of the depolarizing field on the spontaneous polarization in the ultrathin films. Furthermore, statistical analysis of the hysteresis loops has revealed lateral variation of the extrinsic dielectric gap with sub–10-nm resolution. Robust and reproducible ferroelectric properties of nanoscale BiFeO3 indicate its potential for nanoscale applications in information storage and spintronics.
Ophiostomatoid fungi and their roles in Quercus robur dieback in Tellermann forest

Several eastern European countries have reported outbreaks of oak die-back during the 1980’s. Species of Ophiostoma Syd. were isolated from diseased trees and have been suggested to be the possible causal agents of the die-back, but this view have generally not been accepted. In order to monitor the post-outbreak region of oak die-back and to consider the possible role of Ophiostoma spp. in the syndrome, research has been conducted in the Tellerman forest, Voronezh region, Russia between 2005 and 2011. Our study resulted in the isolation of ophiostomatoid fungi from Quercus robur L. trees displaying external signs of desiccation. Fungi were identified based on morphological characteristics and DNA sequence comparisons. Three species of Ophiostoma were identified including O. grandicarpum (Kowalski & Butin) Rulamort, a species closely related to O. abietinum Marm. & Butin, O. fusiforme Aghayeva & M.J. Wingf. and O. lunatum Aghayeva & M.J. Wingf. representing a poorly understood species complex, and most commonly O. quercus (Georgev.) Nannf. Pathogenicity of these fungi was tested using artificial inoculations on Q. robur trees. The fungi were shown to be non-pathogenic and unlikely to play any role in oak die-back. These fungi are most likely only components in a complex of abiotic, biotic and anthropogenic factors that have contributed to a die-back of Quercus spp. in Russia.
The PEP survey: evidence for intense star-forming activity in the majority of radio-selected AGN at z ≳ 1

In order to investigate the FIR properties of radio-active AGN, we have considered three different fields where both radio and FIR observations are the deepest to-date: GOODS-South, GOODS-North and the Lockman Hole. Out of a total of 92 radio-selected AGN, ~64% are found to have a counterpart in Herschel maps. The percentage is maximum in the GOODS-North (72%) and minimum (~50%) in the Lockman Hole, where FIR observations are shallower. Our study shows that in all cases FIR emission is associated to star-forming activity within the host galaxy. Such an activity can even be extremely intense, with star-forming rates as high as ~10^3-10^4 Msun/yr. AGN activity does not inhibit star formation in the host galaxy, just as on-site star-formation does not seem to affect AGN properties, at least those detected at radio wavelengths and for z>~1. Furthermore, physical properties such as the mass and age distributions of the galaxies hosting a radio-active AGN do not seem to be affected by the presence of an ongoing star-forming event. Given the very high rate of FIR detections, we stress that this refers to the majority of the sample: most radio-active AGN are associated with intense episodes of star-formation. However, the two processes proceed independently within the same galaxy, at all redshifts but in the local universe, where powerful enough radio activity reaches the necessary strength to switch off the on-site star formation. Our data also show that for z>~1 the hosts of radio-selected star-forming galaxies and AGN are indistinguishable from each other both in terms of mass and IR luminosity distributions. The two populations only differentiate in the very local universe, whereby the few AGN which are still FIR-active are found in galaxies with much higher masses and luminosities.
evision of primary total hip arthroplasty for peri-prosthetic fracture : prospective epidemiological study of 249 consecutive cases in rance

Background: Revision total hip arthroplasty (reTHA) for peri-prosthetic fracture (PPF) is increasingly performed but still ranks fourth among reasons for reTHA in registries. In France, no specific registry is available and the frequency of PPF among reasons for THA revision is therefore unknown. Here, our objectives were to determine the relative frequency of PPF as a reason for reTHA, to identify patientrelated and primary-THA-related factors associated with reTHA for PPF, to describe reTHA modalities for PPF, and to determine the morbidity and mortality associated with reTHA for PPF. Hypothesis: PPF is the second most common reason for reTHA, after loosening. Methods: Consecutive reTHA procedures performed in 30 French centres over a 2-year period were collected prospectively. Repeat revisions and revisions of hemi-arthroplasties were excluded. The epidemiological, clinical, and surgical data needed to answer the questions of the study were collected. Results: PPF was the second leading reason for reTHA (249/2107, 11.8%). Vancouver type B2 fractures were the most common (n = 127 [51.5%]). Compared to patients who underwent reTHA for reasons other than PPF, those with reTHA for PPF were older at primary THA (67.9 years versus 57.7 years) and more often had intra-operative complications (16.9% versus 11.6%); furthermore, the primary THA was more often cementless (62.7% versus 42.7%) with a dual-mobility cup (20.6% versus 11.1%). At reTHA, the patients with PPF were older (77.6 years versus 69.2 years), had worst medical condition (mean ASA score, 2.4 versus 2.1) and less physically active (mean Devane score, 2.1 versus 2.4). The patients with reTHA for PPF had a shorter time to revision (9.8 years versus 11.4 years), a longer operative time (144 minutes versus 128 minutes), and more frequent use of the posterior approach (77% versus 67%) with a cementless dualmobility cup (78% versus 60%) and a cementless revision femoral stem (72% versus 50%). Morbidity and mortality rates were high (5.9% operative complication rate and 12% of surgical complications with 4.8% mortality within the first 3 months) however, these results were similar to those in the rest of the cohort. Discussion and conclusion: PPF is the second most common reason for reTHA, a result that is at variance with data in national registries. Level of evidence: Level IV, prospective observational cohort study.
New Improved Maximum Power Point Tracking Algorithm for Partially Shaded PV Systems

The paper presents new MPPT algorithm for partial shading of series connected PV cells/modules. In the shaded condition, there is a problem of decrease in the total output power of the PV system. The proposed algorithm aims to reduce this problem by active bypassing of the shaded cells. The algorithm senses the irradiance of each cell and performs calculation in order to decide if to actively bypass the shaded cell or not. Extensive simulation results proved that algorithm works and increases the output power under partial shading conditions. Furthermore, the algorithm becomes more efficient when the number of cells is increased.
Subjective and physiological measures of well-being : an exploratory analysis using birth-cohort data

We use a rich longitudinal data set following a cohort of Swedish women from age 10 to 49 to analyse the effects of birth and early-life conditions on adulthood outcomes. These latter include both well-being and the stress hormone cortisol. Employment and marital status are important adult determinants of well-being. Log family income and absence from school also predict adult well-being, although their importance falls when controlling for adult and birth characteristics. Among the birth characteristics, we find that high birth weight (>4.3kg) affects adult well-being. We predict the level of adult cortisol only poorly, and suggest that the relationship between life satisfaction and cortisol is non-monotonic: both high and low cortisol are negatively correlated with life satisfaction. The results from an OLS life satisfaction regression and a multinomial logit of high or low cortisol (as compared to medium) are more similar to each other.
Inhibition of Staphylococcus Aureus in Hamburger Using Chitosan Film Containing the Nanoemulsion of Trachyspermum Ammi and Bunium Persicum Essential Oils

Introduction: Antimicrobial agents such as essential oils have wide applications, and their use in edible films has been reported to enhance the shelf life of meat and its products. The present study aimed to assess the effects of chitosan films on the inhibition of Staphylococcus aureus in hamburger samples in storage conditions (temperature: 4±1°C). Methods: The prepared films contained 0.8% nanoemulsion of Bunium persicum essential oil (NBPEO) and 1.6% nanoemulsion of Trachyspermum ammi essential oil (NTEO). The hamburger samples were inoculated with S. aureus and divided into several groups, including control (no film), chitosan with 7.5% cellulose nanofiber (Ch-CNF), chitosan with 7.5% cellulose nanofiber, 0.8% NBPEO, and 1.6% NTEO (Ch-CNF-NEO). The samples were preserved in storage conditions (temperature: 4°C), and bacterial count was carried out on days 0, 3, 6, 9, and 12. Data analysis was performed using Bonferroni post-hoc test and repeated measures ANOVA. Results: According to the results, S. aureus count significantly decreased in the treatment groups compared to the control samples. In addition, the maximum reduction rate was observed in the Ch-CNF-NEO treatment (1.41 log CFU/g) compared to the control samples. Conclution: According to the results, it is offered that nanocomposite film of chitosan with nanoemulsion of essential oils practically be applied in hamburger to enhance its safety against S. aureus.
The Impact of Service Quality and Institutional Image on the Satisfaction and Loyalty of Master of Management Students

This study aimed to determine the effect of service quality, image of the institution on the satisfaction and loyalty of master’s degree in management at Universitas Muhammadiyah Jember. The study population was all graduate students in Management Universitas Muhammadiyah Jember, and 50 students of them were taken as samples. Validity and reliability tests are used to test questionnaires which were used as the research instruments. This study was analysed by using linear regression analysis of which influenced student satisfaction. The results of the study indicate that quality of service and institution’s image to public affect student satisfaction. The quality of service and the institution’s image affect student loyalty; in other words, student satisfaction does not affect student loyalty.
