Oscillatory internal shear layers in rotating and precessing flows

We present a direct numerical solution of a particular inertial oscillation, the so-called 'spin-over’ mode, in spherical geometry. This mode is particularly relevant to the fluid flow within a precessing oblate spheroid. We demonstrate that the oscillatory Ekman layer breaks down at ±30° latitude, and that this breakdown spawns internal shear layers. We show that the structure of these shear layers is different for a full sphere and a spherical shell, as noted in the preceding paper (Kerswell 1995). Despite the existence of these shear layers, however, the numerical decay rates agree to within 1 % with the asymptotic decay rates, which neglect any possible shear layers. Finally, we consider the nonlinear mean flow profiles driven by this mode, and demonstrate that our numerical results agree reasonably well with experimental results.
Foreign cultures and level of comfort – a three countries empirical investigation in multinational firms

Level of comfort with foreign cultures (CFC) is one of the critical variables in the ease of working in multicultural work teams. In an increasingly multi-cultural working environment in corporations, the observed and latent behavior influences the working relationship amongst employees and has great weight on individual and team performance. This paper investigates level of comfort among employees, which is influenced by the observed and latent behavior at multinational work places in three countries. A framework has been developed and implemented in Italy, Portugal and India, with a controlled sample design to ensure the cultural diversity. Paper analyses that there is a significant ‘country’ effect on many CFC scales. The Mean score differences based on each of the comfort with foreign culture variables among Portugal, Italy and India are also significant, indicating level of comfort of local cultures with foreign cultures differs from country to country. Key Words: Inter-cultural comfort; Cross cultural teams; Multicultural work places; Cultural identity
Quiet Time Geomagnetic Field Variations in the Equatorial East African Region During the Inclining Phase of Solar Cycle 24

In the present paper, geomagnetic field data obtained from magnetometer measurements at two ground based stations have been used to study solar activity dependence of the solar quiet variations. The study has focused on the horizontal component of the geomagnetic field. The data used in the current study was obtained for all quiet periods from the solar minimum year (2009) through the solar maximum year (2014) to the start of the declining phase (year 2015) of Solar Cycle 24. The present study uses the magnetic data from International Real-time Magnetic Observatory Network (INTERMAGNET) station at Addis Ababa (geomagnetic latitude 0.18°N, geomagnetic longitude110.47°E) and MAGnetic Data Acquisition System (MAGDAS) station at Nairobi (geomagnetic latitude 10.65°S, geomagnetic longitude 108.18°E). The amplitude of mean Sq(H) has shown a dependence on local time of the day and solar activity, with peak values occurring between 1100 LT and 1200 LT and increasing with increase in solar activity; attaining highest values during the solar maximum year. Further, the amplitude of mean Sq(H) at Nairobi is higher than the corresponding values at Addis Ababa in the morning hours around 0700-0800 LT. The local time dependence is attributed to the variation in solar heating and ionization rates while the solar activity dependence is attributed to the increase in electron density with increase in solar activity. The larger morning hours’ amplitudes at Nairobi than Addis Ababa are possibly due to counter electrojet effects close to the geomagnetic equator.
Relationships between flavour and chemical composition of Abondance cheese derived from different types of pastures

The relationships between the flavour and composition of half-cooked pressed Abondance cheese (Haute-Savoie, France) were studied under natural cheese production conditions on the basis of different pastures exploited by 3 producers. Cheeses manufactured from milk pro- duced from mountain pastures (M, n = 5, 1500-1850 m) were deemed to be more "fruity", "animal", "boiled milk" and "hazelnut" and less pungent and "propionic acid" than cheeses made from milk produced from valley pastures (V, n = 5, 850-1100 m). It was possible to partly attribute these differ- ences in flavour to the presence of protein-based volatile compounds in the cheeses. The V cheeses had a greater variety of flavours than the M cheeses. Cheeses from gramineae-rich pastures had the most intense "cooked cabbage" odours, related to the greater amounts of sulphur compounds in these cheeses. Terpenes, which are more abundant in cheeses produced from dicotyledon-rich pastures, did not contribute directly to cheese aroma. The differences in flavour between the cheeses manufactured by the 3 producers were of the same magnitude as those observed between different pastures used by a same producer. The origin of the volatile compounds in the cheeses - whether of microbial origin or from the feed - was discussed.
Modeling Crash Frequency of Heavy Vehicles in Rural Freeways

In the recent years, Prediction models of crash frequency have been employed to estimate accident rate and have been remarkably taken into account for safety improvement plan. Heavy vehicles are one of the main causes of accidents worldwide as there is one out of 9 accidents that they were involved. In this research, a prediction model was developed using heavy vehicles accident data collected from Karaj-Qazvin freeway. In the model, important factors of occurrence of accidents including climatic condition, road surface condition, natural light condition, average vehicle speed, average daily traffic and 5 dangerous violations commitment were considered. Poison regression and negative binomial regression models were employed for modeling purposes. After evaluation of both models, factors including natural light condition, heavy vehicles daily volume, speed limit violation and vehicle defects, especially in lighting system during darkness, were found to be the most effective factors on heavy vehicles accident. 
Reciprocal theorem for the prediction of the normal force induced on a particle translating parallel to an elastic membrane

When an elastic object is dragged through a viscous fluid tangent to a rigid boundary, it experiences a lift force perpendicular to its direction of motion. An analogous lift mechanism occurs when a rigid symmetric object translates parallel to an elastic interface or a soft substrate. The induced lift force is attributed to an elastohydrodynamic coupling that arises from the breaking of the flow reversal symmetry induced by the elastic deformation of the translating object or the interface. Here we derive explicit analytical expressions for the quasi-steady state lift force exerted on a rigid spherical particle translating parallel to a finite-sized membrane exhibiting a resistance toward both shear and bending. Our analytical approach proceeds through the application of the Lorentz reciprocal theorem so as to obtain the solution of the flow problem using a perturbation technique for small deformations of the membrane. We find that the shear-related contribution to the normal force leads to an attractive interaction between the particle and the membrane. This emerging attractive force decreases quadratically with the system size to eventually vanish in the limit of an infinitely-extended membrane. In contrast, membrane bending leads to a repulsive interaction whose effect becomes more pronounced upon increasing the system size, where the lift force is found to diverge logarithmically for an infinitely-large membrane. The unphysical divergence of the bending-induced lift force can be rendered finite by regularizing the solution with a cut-off length beyond which the bending forces become subdominant to an external body force.
Asset Bubbles, Labour Market Frictions and R&D‐Based Growth

Employing an overlapping generations model of research and development (R&D)-based growth with labor market frictions, this paper examines how employment changes induced by labor market frictions influence asset bubbles and long-run economic growth. Asset bubbles can (cannot) exist when the employment rate is high (low), which leads to higher (lower) economic growth through labor market efficiency. We also explore the steady state and transitional dynamics of bubbles, economic growth, and employment. Furthermore, we show that policy or parameter changes that have a negative influence on the labor market can lead to a bubble burst.
Enhanced Heat Transfer in Biporous Wicks in the Thin Liquid Film Evaporation and Boiling Regimes

Biporous media consisting of microscale pin fins separated by microchannels are examined as candidate structures for the evaporator wick of a vapor chamber heat pipe. The structures are fabricated out of silicon using standard lithography and etching techniques. Pores which separate microscale pin fins are used to generate high capillary suction, while larger microchannels are used to reduce overall flow resistance. The heat transfer coefficient is found to depend on the area coverage of a liquid film with thickness on the order of a few microns near the meniscus of the triple phase contact line. We manipulate the area coverage and film thickness by varying the surface area-to-volume ratio through the use of microstructuring. Experiments are conducted for a heater area of 1 cm 2 with the wick in a vertical orientation. Results are presented for structures with approximately same porosities, fixed microchannel widths w � 30 lm and w � 60 lm, and pin fin diameters ranging from d ¼3‐29 lm. The competing effects of increase in surface area due to microstructuring and the suppression of evaporation due to reduction in pore scale are explored. In some samples, a transition from evaporative heat transfer to nucleate boiling is observed. While it is difficult to identify when the transition occurs, one can identify regimes where evaporation dominates over nucleate boiling and vice versa. Heat transfer coefficients of 20.7 (62.4) W/cm 2 -K are attained at heat fluxes of 119.6 (64.2) W/cm 2 until the wick dries out in the evaporation dominated regime. In the nucleate boiling dominated regime, heat fluxes of 277.0 (69.7) W/cm 2 can be dissipated by wicks with heaters of area 1 cm 2 , while heat fluxes up to 733.1 (6103.4) W/cm 2 can be dissipated by wicks with smaller heaters intended to simulate local hot-spots.

Anaerobically digested food waste in compost for Agaricus bisporus and Agaricus subrufescens and its effect on mushroom productivity.

BACKGROUND Source-separated food waste is increasingly being treated by means of hygienisation followed by anaerobic digestion. The fibrous digester residue (digestate) is a potential mushroom substrate, while heat from the biogas can provide steam for the cultivation process. Using bag experiments the present study explored digestate as a full substitute for chicken manure conventionally used in mushroom composts. RESULTS After mixing, a rapid temperature development in the compost was stimulated by a small amount of chicken manure, as aerobic microbial seeding. Mechanical elimination of lumps was essential for full mycelial colonisation. Three straw digestate composts had Agaricus bisporus mushroom yields above 370 g kg⁻¹ substrate. The optimal compost water content was 600 g kg⁻¹ at inoculation, and high digestate content (up to 500 g kg⁻¹ by dry weight) did not affect yield for this species. High yields of A. subrufescens (200 g kg⁻¹) were related to drier composts of lower digestate content (more straw) and lower pH values at inoculation. CONCLUSION Digestate successfully substituted chicken manure in straw composts without affecting mushroom yields for both species. There were no clear differences between straw digestate and control composts in terms of mushroom dry matter, size, nitrogen or ash content.
Translational perspectives on MSMB and CRISP3 expression and regulation in prostate cancer

Prostate cancer is currently the most common form of cancer in Sweden. Currently, the only biomarker used in the clinic is serum PSA, and there is a great need for new biomarkers that may increase the diagnostic and prognostic information so that better predictions can be made, and treatment may be tailored. Here, we have investigated two proposed biomarkers microseminoprotein-β (MSMB) and cysteine-rich secretory protein-3 (CRISP3). Firstly, we wanted to validate previous findings, that MSMB and CRISP3 are predictors of recurrence in patients undergoing radical prostatectomy for localized prostate cancer. Using a novel automated image analysis tool, IHC-MARK, we found that MSMB was an independent predictor of recurrence in a large patient cohort. Further, we showed that expression of both MSMB and CRISP3 was induced by androgen in vitro, and MSMB was decreased in patients receiving androgen deprivation therapy prior to radical prostatectomy. MSMB was virtually lost in advanced prostate cancer, in contrast to CRISP3 which was highly expressed. Inflammation has been suggested to be a primary aetiological event in prostate cancer and the presence of putative binding elements for inflammatory transcription factors in the promoter region of CRISP3 led us to hypothesise that CRISP3 may be regulated by inflammatory stimuli. Instead, stimulation of prostate cancer cells with interleukin (IL)-6 strongly induced MSMB expression but had no effect on CRISP3 expression. A long-term IL-6 stimulated cell line, however, had no MSMB expression, probably due to DNA methylation. Finally, expression of MSMB in cell lines without endogenous MSMB resulted in decreased cyclin D1 expression and reduced proliferation. In conclusion, MSMB is an independent predictor of recurrence, whereas the value of CRISP3 as a biomarker remains to be elucidated. In vitro studies show that MSMB may be important for prostate cancer proliferation, but more studies on MSMB and CRISP3 functions are warranted.
Indoor Level of Polybrominated Diphenyl Ethers in the Home Environment and Assessment of Human Health Risks

ABSTRACTIt has been demonstrated that human exposure to polybrominated diphenyl ethers (PBDEs) might be associated with several adverse health effects. Dietary and microenvironmental sources are considered to be the main routes of PBDEs exposure. The study aimed to investigate PBDEs in residential indoor and outdoor air and further to assess the health risks in family members of different ages. Indoor and outdoor air samples from houses in residential areas were simultaneously collected for analysis of BDE-47, 99, 100, 153, 154, 183, 196, 197, 203, 206, 207, 208, and 209 by high-resolution gas chromatography/high-resolution mass spectrometry. PBDE concentrations were non-significantly higher indoors (81.1 pg/m3) than outdoors (42.7 pg/m3) (p = 0.513). For the outdoor air, the mean PBDE level was lower in air outside houses than in air from industrial and urban areas. Levels of Σ14PBDEs and BDE-209 in house indoor air were no higher in Taiwan than other countries. The daily intake of non-dietary PBDEs from house air and dust in Taiwan was highest in the toddlers (1–2 years old; 8.22 ng/kg b.w./day) and lowest in the male adults (≥ 20 years old; 0.562 ng/kg b.w./day) among family members. For Taiwanese, the risks of non-cancer (hazard quotient: HQ) and cancer (cancer risk: R) with neurobehavioral effects of exposure to non-dietary PBDEs in the home environment were assessed to be lower than the critical values of 1.00 and 1.00 × 10–6 for HQs and Rs, respectively. In conclusion, levels of indoor PBDEs and non-dietary daily intake were found to be low in home environments in Taiwan. This result suggests that PBDEs in the home environment are not harmful to family members from the newborn to the elderly if we only consider the neurobehavioral effects.
Catalogue of time aligned profiles of 56 pulsars at frequencies between 102 and 10500 MHz

A catalogue of integrated pulse proles of 56 pulsars with observations at 102, 230, 408, 610, 1400, 4700, and 10500 MHz is presented. The proles are aligned in time (phase) so that direct comparisons of changes in the prole shape and component composition can be made. Smearing due to interstellar scattering at low frequencies for pulsars with large dispersion measures was removed by means of a special \descattering" method (Kuzmin & Izvekova 1993). Most pulsars show good alignment over the whole fre- quency range 0.1 to 10.5 GHz, if the dispersion measure is corrected slightly in comparison to the published value. We conrm a non-dispersive time shift of the integrated prole for PSR 0809+74 as presented by Bartel et al. (1981), Davies et al. (1984), and Kuzmin et al. (1986). This paper presents the data in form of a catalogue of time aligned proles. A detailed analysis of the change of pulse structure with frequency by means of a decomposi- tion of the average pulse shape into gaussian components will be presented in a forthcoming paper.
Information needs and seeking behavior among primary care physicians in Saudi Arabia: Implications for policy and practice

This is an exploratory study conducted in Riyadh region, Saudi Arabia to determine information needs and information-seeking behavior among rural and urban primary health care physicians. The study employed self-administered questionnaires to collect data on demographic characteristics, types of medical and health information needed, sources sought and barriers encountered by physicians. The questionnaires were distributed to all primary health care physicians in Riyadh region between August and November 2010. The results indicated that physicians in rural areas were less likely to have access to medical and health information than their counterparts in urban areas, particularly for modern sources such as online databases, medical journals and the Internet websites. Physicians in both geographical locations reported similar individual and organizational barriers that hinder using information resources. Acquiring primary care physicians, particularly in rural areas with access to medical and health information is vital in the provision of primary health services. Efforts are needed to facilitate primary health care facilities with necessary information infrastructure that help develop the profession and provide quality of health care to a large segment of the population who use such health facilities. Key words: Primary health care, rural, urban, information-seeking behavior, Saudi Arabia.
Tourist perception of risk: Chengdu research base for giant panda breeding (CRBGPB)

The aim of this paper is to provide insight into wildlife tourists' risk perceptions relevant to the experience of interacting with giant pandas in a semi-captive setting. A survey of tourists to the Chengdu Research Base for Giant Panda Breeding (CRBGPB) resulted in 650 valid questionnaires. Descriptive statistics, independent-samples t-tests and one-way analysis of variances (ANOVAs) were used to explore the influence of demographic characteristics and tourist behaviour on risk perception. Perceptions relating to risks associated -with the quality of the tourism experience were the most high, whilst physical risk perception was the lowest. The most important finding was that risk perception for the CRBGPB experience was low.
Do Our School Programmes Motivate Youth for Quality? - A Case from Slovenia

Purpose: The paper highlights the issue of teaching for quality in our regular higher education programmes – just to have an insight into the situation and to find some improvement opportunities. Design/methodology/approach: Analysing a case from Slovenia our survey study focuses on quality management related courses at all the levels of education to see if they follow the realized importance of quality management in all spheres of life proved through literature review, manager claims and even through politician and journalist statements. It also analyses final student papers (undergraduate, graduate, master and doctoral theses) that could signal the students' interest in quality management. Findings: Slovenian education institutions do follow quality requirements regarding institution management. However, they offer only few specific quality management related courses. Additionally, less than 5% of published final student papers in faculties offering quality management related programmes are related to quality matters. Research limitations/implications: The analysis of quality management related final student papers was limited only to the biggest Slovenian University in this preliminary research. It should be followed by some more detailed research on this topic giving stronger suggestions. Practical implications: School programmes should cover business needs regarding quality management knowledge and skills. Social implications: Teaching for quality through regular school programmes would be the most effective and systematic way to improve the culture of quality and responsibility in the society and to implement it in our organizations as well. Originality/value: The literature review showed some research on quality management of the higher education institutions. However, no research on quality topics in their offered courses and in student papers has been found.
Transdimensional inversion of ambient seismic noise for 3D shear velocity structure of the Tasmanian crust

ABSTRACTAmbient seismic noise tomography has proven to be a valuable tool for imaging 3D crustal shear velocity using surface waves; however, conventional two-stage inversion schemes are severely limited in their ability to properly quantify solution uncertainty and account for inhomogeneous data coverage. In response to these challenges, we developed a two-stage hierarchical, transdimensional, Bayesian scheme for inverting surface wave dispersion information for a 3D shear velocity structure and apply it to ambient seismic noise data recorded in Tasmania, southeast Australia. The key advantages of our Bayesian approach are that the number and distribution of model parameters are implicitly controlled by the data and that the standard deviation of the data noise is treated as an unknown in the inversion. Furthermore, the use of Bayesian inference — which combines prior model information and observed data to quantify the a posteriori probability distribution — means that model uncertainty information can b.
Pleurotus Spent Mushroom Compost as Green Supplementary Nutrient in Tissue Culture

This study investigates the effect of Pleurotus spent mushroom compost as green supplementary nutrient in tissue culture. Different concentration of Pleurotus spent mushroom compost in powder (SMC) and activated carbon (SMCAC) were added into Murashige and Skoog media (MS) with 0.1 mg/L 6-benzylaminopurine (BAP). The shoot regeneration of Clinacantus nutans plant such as number of shoots, number of leaves and length of leaves were recorded for four weeks. Collected data was analyzed using one way analysis of variance (ANOVA) and Tukey test through the SPSS Statistics 21 software. The 0.1 g/L SMC recorded the highest leaves numbers. Meanwhile, 0.2 g/L SMC showed highest performance in length of shoot. The SMCAC showed a negative response in number of leaves and shoot as well as length of shoot. In summary, the SMC showed significant performance in number of leave and shoot length but less effective on number of shoot. In contradictory, the SMCAC reported poor performance in shoot regeneration but contribute in absorption of nutrient from environment and storage of the nutrient asfunction of biochar. Therefore, the SMC has a high potential as a green supplementary nutrient for tissue culture. The application of this material has contributes into the green technology via convert waste to product, which is in-line with zero waste concept.
