UDK 631.4:632.954; 633.1:632.954(497.6) The aim of the study is to present the elements which must be considered while determining the risk of the mobility of the herbicides. Herbicides used for maize production have the special eco toxical significance and special risk because some are potentially mobile, they are used on the large surfaces during the rainy period and near rivers. Behaviour of the herbicides in the environment, particularly in the soil is very complex. It does not depend only on the characteristics of the herbicide, but on the many factors of the environment which are very variable. Regardless of this fact, there are experimentally determined physical-chemical indicators for each herbicide that show the possible behaviour of herbicides in the environment. Studied physical-chemical indicators of herbicide behavior are: Distribution Coefficient (Kd); Organic Carbon Partitioning Coefficient (Koc); Time of the Semi-Decomposition (DT50); Water Solubility (S); Groundwater Ubiquity Score (GUS); Henry's Law Constant (Kh), Vapor Pressure (PV) and the Dissociation Constant (pKa). Namely, herbicides, in larger or smaller measure, have “leaching potential“, which is ability to reach the underground water. One of the basic criteria for evaluating the herbicide ability to reach the underground water is related to indicators of mobility and persistency (DT50) herbicides, but neglecting some other criteria in that evaluation such as the amount of applying, characteristics of the soil and the aim of the crop growth. According to the EPA criteria, for the herbicides used in maize production in Bosnia and Herzegovina (BiH), the “trigger“ value will indirectly indicate if the herbicides have large leaching potential.

AbstractBackgroundGraded exercises tests are performed in adult populations; nonetheless, the use of this type of assessment is greatly understudied in overweight and obese adolescents.ObjectiveTo investigate heart rate autonomic responses to submaximal aerobic exercise in obese and overweight adolescents.MethodsWe recruited 40 adolescents divided into two groups: (1) overweight group comprising 10 boys and 10 girls between Z-score +1 and +2 and (2) obese group comprising 10 boys and 10 girls above Z-score >+2. Heart rate variability was analysed before (T1) and after exercise (T2–T4) on treadmill at a slope of 0%, with 70% of the maximal estimated heart rate (220 – age) for 20 minutes.ResultsHeart rate in the overweight group was: 93.2±10.52 bpm versus 120.8±13.49 bpm versus 94.6±11.65 bpm versus 93.0±9.23 bpm, and in the obese group was: 92.0±15.41 bpm versus 117.6±16.31 bpm versus 92.1±12.9 bpm versus 91.8±14.33 bpm. High frequency in the overweight group was: 640±633.1 ms2 versus 84±174.66 ms2 versus 603.5±655.31 ms2 versus 762.6±807.21 ms2, and in the obese group was: 628.4±779.81 ms2 versus 65.4±119.34 ms2 versus 506.2±482.70 ms2 versus 677.9±939.05 ms2; and root mean square of successive differences in the overweight group was: 37.9±18.81 ms versus 10.9±8.41 ms versus 32.8±24.07 ms versus 36.7±21.86 ms, and in the obese group was: 38.7±23.17 ms versus 11.5±8.62 ms versus 32.3±16.74 ms versus 37.3±24.21 ms. These values significantly changed during exercise compared with resting values in overweight and obese groups. Moreover, we also reported no significant difference of resting parasympathetic control of heart rate between obese and overweight adolescents.ConclusionThere was no significant difference of autonomic responses elicited by submaximal aerobic exercise between overweight and obese adolescents.

Background: Inappropriate antimicrobial use continues to threaten modern medicine. The ongoing pandemic likely exacerbated this problem because COVID-19 presents similarly to bacterial pneumonia, confusion exists regarding treatment guidelines, and testing turnaround times (TATs) are slow. Our primary object was to quantify antimicrobial use changes during the pandemic to rates before the crisis. A subanalysis within the COVID-19 cohort was completed based on SARS-CoV-2 status. Methods: The pre–COVID-19 period was January–May 2019 and the COVID-19 period was January–May 2020. Subanalyses were used to explore differences in antibiotics use between persons not under investigation (non-PUIs), SARS-CoV-2–negative PUIs, and SARS-CoV-2–positive PUIs. Non-PUI patients were those without respiratory symptoms and/or fever. The χ2 and Wilcoxon signed rank-sum tests were used for analysis. Results: During the 2019 and 2020 study periods, 7,909 and 7,283 patients received >1 antimicrobial, respectively (Figure 1). Overall, antibiotic therapy per 1,000 patient days increased from 633.1 before COVID-19 to 678.5 during COVID-19, a 7.2% increase (Table 1). Notably, broad-spectrum respiratory antibiotics demonstrated a significant increase between pre–COVID-19 and COVID-19 cohorts (p < 0.001). Of the 7,283 patients within the COVID-19 cohort, 34.7% (n = 2,532) were PUI and 13.8% (n = 1,002) of these patients tested SARS-CoV-2 positive. Again, broad-spectrum respiratory antibiotics use was significantly increased for COVID-19 patients (p < 0.001). Of note, the proportion of patients receiving respiratory antibiotics steadily decreased over time (R2 = 0.99). Conclusions: There was a significant increase in antibiotic use during the COVID-19 pandemic. Encouragingly, antimicrobial use decreased over time, likely due to (1) faster TATs, (2) real-time education to clinicians and subsequent de-escalation of unnecessary antimicrobials, and (3) development of treatment guidelines as new research emerged.Funding: NoDisclosures: None

Context. The general theory of relativity predicts the redshift of spectral lines in the solar photosphere as a consequence of the gravitational potential of the Sun. This effect can be measured from a solar disk-integrated flux spectrum of the Sun’s reflected light on Solar System bodies. Aims. The laser frequency comb (LFC) calibration system attached to the HARPS spectrograph offers the possibility of performing an accurate measurement of the solar gravitational redshift (GRS) by observing the Moon or other Solar System bodies. Here, we analyse the line shift observed in Fe absorption lines from five high-quality HARPS-LFC spectra of the Moon. Methods. We selected an initial sample of 326 photospheric Fe lines in the spectral range between 476–585 nm and measured their line positions and equivalent widths (EWs). Accurate line shifts were derived from the wavelength position of the core of the lines compared with the laboratory wavelengths of Fe lines. We also used a CO5BOLD 3D hydrodynamical model atmosphere of the Sun to compute 3D synthetic line profiles of a subsample of about 200 spectral Fe lines centred at their laboratory wavelengths. We fit the observed relatively weak spectral Fe lines (with EW< 180 mÅ) with the 3D synthetic profiles. Results. Convective motions in the solar photosphere do not affect the line cores of Fe lines stronger than about ∼150 mÅ. In our sample, only 15 Fe I lines have EWs in the range 150< EW(mÅ) < 550, providing a measurement of the solar GRS at 639 ± 14 m s−1, which is consistent with the expected theoretical value on Earth of ∼633.1 m s−1. A final sample of about 97 weak Fe lines with EW < 180 mÅ allows us to derive a mean global line shift of 638 ± 6 m s−1, which is in agreement with the theoretical solar GRS. Conclusions. These are the most accurate measurements of the solar GRS obtained thus far. Ultrastable spectrographs calibrated with the LFC over a larger spectral range, such as HARPS or ESPRESSO, together with a further improvement on the laboratory wavelengths, could provide a more robust measurement of the solar GRS and further testing of 3D hydrodynamical models.

Research was conducted at Reading University over three growing seasons into alternatives to herbicides m spnng cereals by identifying traits that enhance crop competitive ability and exammmg the role of seed quality in Integrated Weed Management (IWM~. Nine spring wheat genotypes, spring Barley, spring Triticale and a mixture of spring wheat genotypes Paragon and Belvoir were monitored for their competitive ability in three weed treatments, i.e. weed free and with model weeds Sinapis alba L. or Avena sativa L. The ranking of competitive ability (CA) was estimated from both crop tolerances to weed pressure (i.e. a low crop grain yield loss - CYL) and weed suppression. Genotypic differences in CA were repeatable, with CYL of 28%, 39% and 28-75% for barley, triticale and wheat in 2003, respectively. Barley also suppressed weed biomass by 59% more than wheat. Among wheats, Axona consistently maintained higher yields (10% CYL in 2002 and 46% in 2003). Paragon suppressed weeds by 63% in 2002 and 50% in 2003 whereas cv. Status was a poor competitor. The wheat mixture reduced CYL but had no significant effect on weed suppression. An important observation for variety trials was that the ranking for grain yields in weed free plots was inconsistent with those with weeds. Competitive genotypes tended to be taller and have rapid early growth at GS 15 giving early ground cover, a higher absolute growth rate at GSI5, a shorter mean time to emergence and higher early leave area. On seed quality and its interactions with agronomic practices such as seeding rate and sowing date, doubling seed rate improved crop competitiveness if the crop was sown at the same time as weeds rather than a week later. When a vigorous seed lot was used, higher number of seedlings, ground cover, harvest index and number of fertile tillers per m2 and lower mean time to emergence contributed to its higher crop grain yield. High vigour seeds suppressed total weed biomass up to 89,-43 and 63% in three experiments, the suppression varying between individual weed species. For example, when natural weed infestations were present, high vigour seeds suppressed Convolvulus arvensis L. by 52.5% and Solanum nigrum L. by 95.5%. One particular feature of this thesis was an attempt to understand why high vigour seeds are more competitive. The results indicated that more than 75% of the variations in grain yield and 81 % of the variation in weed dry mutter suppression can be accounted for due to achieving more rapid emergence than the weeds.

Genetic resistance to Wheat streak mosaic virus (WSMV) offers the most attractive and environmentally safe strategy for disease control. While effective resistance in hexaploid bread wheat (Triticum aestivum) has recently been described in only one case, the Wsm2 gene, more successful resistance has been introgressed from the related hexaploid wheatgrass, Thinopyrum intermedium, as the Wsm1 and Wsm3 genes. In the current study, fluorescent in situ hybridization (FISH) with genomic DNA from Th. intermedium, Aegilops tauschii and repetitive DNA probes was applied to four breeding populations of wheat-Th. intermedium, previously tested for WSMV-resistance. Three different wheat-Th. intermedium recombinant chromosomes, the well-known 4Ai#2S.4DL and two novel, 1B and 3D, were identified to be associated with WSMV-resistance. These novel introgressed genes from Th. intermedium were designated as Wsm4 and Wsm5 respectively. The Wsm4 gene was pinpointed to a 6% interstitial map region on the 1BS flanked by Xgwm4144 and Xgwm1100 markers. Six new PCRmarkers, five linked to Wsm1 and one to Wsm4 were identified. Molecular markers now provide a good coverage of the 4Ai#2S arm for effective marker assisted selection and the new genes increase our arsenal to combat the disease. Two highly repetitive satellite DNA families, Afa and pSc119.2, were isolated for the first time from Th. intermedium and their diversity in respect to copies from other Triticeae species were investigated. They showed contrasting evolutionary dynamics leading to time dependent or independent homogenization of Afa and pSc119.2 sequences. Both repeats are excellent cytological markers and characterized the 4Ai#2S chromosomal arm, in the alien wheat lines and the Th. intermedium genome. Southern hybridization, with methylation sensitive and insensitive restriction enzymes and immunostaining with anti-5-methyl-cytosine antibodies were employed to assess DNA methylation. Overall, no massive changes were evident in the wheat genome, however the alien arm showed reduced cytosine methylation which is characteristic for actively transcribing chromatin.

Modern annual arable crops are susceptible to outbreaks of pests due mainly to the uniform habitats that agricultural fields represent. Cereals are particularly prone to infestations of aphids, which may damage the crop directly through herbivory, or indirectly by acting as vectors of disease. These insects, however, have a large range of invertebrate natural enemies, which under certain circumstances, can maintain infestations below economically damaging levels. Greater habitat complexity at landscape and farm scale usually leads to more diverse assemblages of natural enemies at the field scale, but such diversity less often translates to a higher risk for pests. When higher natural enemy diversity is associated with lower levels of pest control, intraguild predation (IGP) is often cited as one of the primary antagonsitic mechanisms. IGP occurs where predators not only compete for the same resource, but also partake in a trophic interaction with one another. Controlled experiments suggest that the niche proximity of predators relative to each other and their shared prey may help predict the outcome of multiple- predator interactions. The primary aim of this thesis was to assess levels of IGP amongst generalist invertebrate predators and to elucidate their spatial patterns, in fields of winter wheat (Triticum aestivum), an important cereal crop in North-West Europe. The chief objective was to establish the regulatory abilities of these predators in the control of aphids. Post-mortem gut content analysis using PCR was used to establish the intensity of IGP by two polyphagous predators, the carabid beetles Pterostichus melanrius and P. madidus, on a number of insectivorous linyphiid spiders and their shared aphid prey. Each of the spiders tested was found to suffer IGP. Predation rates were adjusted using data from controlled feeding trials and resampled using Monte Carlo models to test the hypothesis that predation was density-dependent. In one experiment, the web-occupying linyphiid Tenuiphantes tenuis was consumed by up to a third of P. melanarius. Predation rates by carabids on the linyphiid Bathyphantes gracilis were consistently lower than expected. B. gracilis also relies principally on its web to capture prey, but builds these webs significantly higher in the wheat stem than T. tenuis . Preferences for intraguild prey species more likely to hunt aphids on the ground, the tetragnathid spider Pachygnatha degeeri, and the linyphiids Erigone spp. (E. atra and E. dentipalpis ), were less consistent than those species more dependent on their webs to hunt aphids and other prey. While many factors may contribute to the outcomes of multi-predator interactions, these findings broadly supported the hypothesis that niche proximity of intraguild predators is positively related to levels of disruption due to intraguild interactions.

There is increasing pressure from government legislation and supermarket quality assurance schemes to reduce chemosynthetic pesticide-inputs in conventional production systems. This has resulted in the need to study potential management based approaches to develop alternative management (e.g. rotational design or crop nutrition) strategies and/or crop breeding/variety selection based approaches to reduce disease pressure or crop resistance to biotic stress. Two long-term, factorial field trials (the NSCS and the NUE-crops trials) were used to assess effects of fertiliser input types (composted manure vs mineral fertilisers), fertiliser input levels, pre-crop/rotational position, crop protection (with and without the use of chemosynthetic pesticides) and wheat genetics/variety choice on phenolic profiles in flag leaves, foliar disease severity and grain yield in winter wheat. Interactions between crop management practices and growing season were investigated using univariate and redundancy analysis approaches. Flag leaf concentrations of phenolic compounds differed between years and plant growth stages and were higher (approx 40%) in crops fertilised with organic compared to mineral fertilisers, but there were virtually no effects of crop protection on phenolic profiles. In contrast, both disease severity and crop yield were significantly affected by crop protection and fertilisation practices. The use of conventional, pesticide based crop protection resulted in lower disease severity and higher yields and mineral NPK fertilisers resulted in lower Septoria and higher mildew and stripe rust severity. Effects of precrop/rotational position and wheat genetics/variety choice, and interactions between precrop, fertilisation, crop protection and/or variety choice were also detected for phenolic profiles, disease severity and grain yield. RDA identified (a) positive associations between organic fertilisation and radiation, and concentrations of phenolic compounds in leaves, (b) positive associations between organic crop protection and relative humidity, and disease severity and (c) negative associations between concentrations of most phenolic compounds and disease severity. Results indicate that it is possible to increaseing concentrations of phenolic compounds in cereals via changes to fertilisation practices, and that this may (a) reduce disease severity and/or increase crop yield in cropping systems which omit chemosynthetic pesticides, but (b) may have no effect on disease and reduced crop yields in cereal cropping systems which use pesticides. However, varietal differences in leaf phenolic expression under organic fertilisation could not be linked to differences in disease severity and yields.

Spot blotch is one of the most important diseases of barley (Hordeum vulgare) in Libya and worldwide. The overall aim of this study was to investigate the potential of biological control in combination with disease resistance to control spot blotch without the potential hazards of chemical application. Fungi were isolated from barley plants with spot blotch symptoms from different areas in Libya. As well as the commonly known spot blotch pathogen Bipolaris sorokiniana (teleomorph Cochliobolus sativus), Bipolaris spicifera (teleomorph Cochliobolus spicifer), Curvularia inaequalis, and Alternaria alternata were identified by their morphology and ribosomal DNA sequences. Bipolaris sorokiniana was the most serious pathogen under the test conditions; the others infected barley but caused less severe symptoms. Spot blotch resistance of barley seedlings was tested under greenhouse conditions with four Libyan cultivars (ACSAD, Nibola, Rehan, and Wadi Utbah) and two UK cultivars (Gaelic and Pastoral). Nibola was the most resistant. The ability of the organisms in three commercial biocontrol products, Trichoderma harzianum T-22 (Trianum), Streptomyces lydicus WYEC 108 (Actinovate) and Bacillus subtilis QST 713 (Serenade), to control spot blotch individually and in combination was investigated. On agar plates, all three inhibited growth of the pathogens completely on the second day of culture, except that for B. spicifera with S. lydicus there was an inhibition zone and the pathogen grew in the opposite direction. Disease severity was lowest when T. harzianum T-22 was applied individually to the most resistant cultivar, Nibola. Foliar application, soil treatment and seed coating all reduced disease severity. With foliar application, T. harzianum T-22 was more effective when applied at the same time as the pathogen than when applied one week before or four days after. In a field experiment with T. harzianum T-22, foliar application combined with seed treatment suppressed spot blotch more effectively than either method individually.

Published research showed there was a link between the abundance of septoria diseases (Zymoseptoria tritici and Parastagonospora nodorum) and sulphurous acid in acid rain. Historical records showed that P. nodorum was at a peak in 1970s while Z. tritici became more abundant at 1980s. Another, small scale, study showed that both pathogens were affected by sulphur, but Z. tritici was reduced more by sulphur than P. nodorum. These studies suggested it could be useful to investigate the effect of sulphur fertilizer under larger scale, field, conditions. Thus, the aim of this project was to study if sulphur fertilizer affects the abundance of these pathogens, and to study if sulphur fertilization alters the yield and quality of wheat under disease pressure. A further question was whether silicon fertilizer affects both pathogens and the yield and quality of wheat. A final aspect of this thesis was to develop a way to quantify pathogens by using qPCR assay on large field samples. A glasshouse experiment showed that all wheat cultivars were susceptible to available pure isolates of both pathogens, but the proportion of leaves infected by these isolates varied between cultivars. Cv. Paragon showed a high proportion of infected leaves in comparison with Gallant and Maris Huntsman (M. Huntsman). Three successive field experiments were conducted. Z. tritici infected all plots, so it was not possible to estimate changes in competitive effects due to the fertiliser regimes. In the field experiments a variety of measurements were used at different growth stages to assess the diseases. The proportion of leaves infected with, and disease severity of, Z. tritici were not significantly affectedly by sulphur fertilization in 2013. In two further experiments, proportion of leaves infected with, and spore concentration of, Z. tritici were reduced by sulphur fertilization. In the 2014-2015 experiment disease severity of Z. tritici was significantly reduced by sulphur fertilization. Although autumn spray and seed inoculation with P. nodorum did not succeed, a spring spray inoculation was successful in the 2014-2015 experiment. In this experiment, proportion of leaves infected and disease severity of both fungi were reduced by sulphur fertilization. but Z. tritici was reduced more than P. nodorum. These results agree with the historical trends. Yield and quality measurements results showed that sulphur fertilization increased yield and the wheat quality was improved. This result was obtained when the sulphur fertilization was split and applied at multiple times throughout the growing season of wheat (Table 6).

Wheat is one of the main staple food crops, providing an essential source of carbohydrates for millions of people. Therefore, demand for wheat will increase in next few decades as the global population increases toward a prediction 9 billion by 2050. Further advances in wheat yield requires the integration of new tools and strategies to complement traditional approaches to select genotypes that are better suited to abiotic stress, in the context of climate change. Identifying morphological and physiological characters, correlated with tolerance to environmental stress, is a priority for wheat breeders. One approach that can be combined in wheat breeding programmes is to create new genetic variation, for example by crossing wheat with close relatives such as spelt. The overall objective of this study is to investigate the physiological traits associated with radiation use efficiency (RUE) in a segregating population of 225 recombinant inbred lines, originating from the cross of wheat (cv. Forno) with spelt (cv. Oberkulmer). Three field experiments from 2010 to 2012 were carried out at Sutton Bonington. All lines, and their parents, were grown as ear rows in 2010 and arranged in randomized design with one replicate of mini plots in 2011. In 2012 three replicates were grown in a randomised complete block design. In these experiments, plant development, RUE, biomass, grain yield and associated physiological traits were measured in the recombinant inbred lines. In addition, a glasshouse experiment was conducted in 2013 to investigate gas exchange traits amongst 18 selected lines with a wide range of RUE, alongside the parents.

Self-assembled monolayers (SAM) formed on gold or hydroxylated surfaces are well ordered organic surfaces that enable the control of interface property at the molecular scale. Microcontact printing is a simple technique that can pattern the formation of SAM in the plane with dimensions on the micron scale. The combination of SAM and microcontact printing makes a technique useful for studying a variety of fundamental phenomena in bio-interfacial science such as cell adhesion. However, the existence of surface roughness tends to impede the effectiveness of the method in generating the desirable interface properties. Studies have shown that surface roughness significantly changes adhesion of SAM coated material. The current study tries to understand the roughness effects on bio-adhesion of cell-SAM substratum. A current model of cell adhesion considers the effects of nonspecific and specific interactions between adhesion molecules and the substrate assuming an isotropic Gaussian distributed roughness. Simulation results show the change of pull-off force and contact area due to different scales of roughness. The reduction rate of cell adhesion due to roughness and chemical-mechanical factors are then compared to show the significance of roughness effects on SAM adhesion. Results suggest that caution must be taken in quantitative interpretation of protein and cell adsorption strength by using SAM device as a biosensor.

Lubrication characteristics between a cylinder block and a valve plate in axial piston pumps play an important role in volumetric efficiency and durability of a hydraulic unit. In this paper, the finite element method is used for the computation of the pressure distribution between a cylinder block and a valve plate of the axial piston pump. Also, the Runge-Kutta method is applied to simulate the dynamics of a cylinder block of three-degrees of freedom motion. From the results of computation, two major conclusions are drawn. One is related to the fluid film characteristics between a cylinder block and a valve plate, and the other is related to the average leakage flow rate which is determined by the pressure gradient and the clearance near the discharge port. To confirm results of numerical simulation of cylinder block dynamics, experiment is conducted using three eddy-current type gap sensors, which are imbedded at the pump housing. Finally, a revised shape of a valve plate is proposed which increases the stability of the cylinder block dynamics and the volumetric efficiency of the pump based on numerical simulation.

Chlorine- and sulfur- and phosphorus-containing compounds are commonly added to the base fluid to synthesize lubricants used under extreme-pressure (EP) conditions. Analyzing the resulting tribological films on iron reveals that chlorinated hydrocarbons thermally decompose forming a layer that consists of iron chloride (FeCl2) or carbide (Fe3C), and that dialkyldisulfides react to form FeS and Fe3C. Alkyl phosphates thermally decompose on iron oxide to form alkyl and alkoxy, as well as POx species, on the surface. The alkyl and alkoxy species thermally decompose on heating to evolve gas-phase products and deposit carbon onto the surface. The POx species rapidly diffuse into the oxide forming a film that consists of a carbonaceous layer covering a phosphate film. The tribological properties of evaporated and reactively grown thin films have been investigated in ultrahigh vacuum. This strategy eliminates contamination and allows films of known composition and structure to be grown on well-characterized substrates. Three tribological regimes are identified depending on film thickness. In the first regime, an initial rapid decrease in friction is found when a film that is a few nanometers thick (corresponding to a monolayer) covers the surface. The friction coefficient increases once again in the second regime as the film becomes thicker, due to the increased contact area between the film and the rough tribotip, and the behavior is well described by a modified Greenwood-Williamson model. A third regime is found when the film becomes thicker than the interfacial roughness, where the surfaces are completely separated by the film. Finally, measuring the friction coefficients of thin halide films deposited onto various substrates, where the local pressure at the asperity tips depends on the substrate hardness, shows that the shear strength of the “monolayer” films depends on pressure.

The presence of rigid abrasive contaminant between the plunger and sleeve of high-pressure injection fuel system causes scuffing failure. The abrasive contaminant is modeled as a spherically shaped rigid particle. The contaminant is envisioned to penetrate into the sleeve while positioning itself in rubbing contact with the plunger. Excessive temperature rise known as flash temperature between the particle-plunger interface is used as an indication of whether scuffing would take place. The model uses flash temperature in conjunction with the material properties to determine the critical particle size that may result in scuffing failure. The range of critical particle size initiating significant abrasive wear is determined and validated with the experimental results available in literature. Our predicted model can be used as a guide for selecting an appropriate filter size for high-pressure injection fuel system.

The pumping effect which is proposed by the authors to explain the accumulation of liquid-like chemicals on the air bearing surface has been analyzed by taking into the account the incline of the air bearing surface. Numerical results show that the accumulation rate of the contaminant decreases as the incline of the air bearing surface increases and at the same time the maximum adsorbed film thickness shifts from the outlet to the inner surface.

Numerous investigations have been conducted to extend adiabatic liquid-gas VOF flow solvers to include condensation phenomena by adding an energy equation and phase-change source terms. Some proposed phase-change models employ empirical rate parameters, or adapt heat transfer correlations, and thus must be tuned for specific applications. Generally applicable models have also been developed that rigorously resolve the phase-change process, but require interface reconstruction, significantly increasing computational cost and software complexity. In the present work, a simplified first-principles-based condensation model is developed, which forces interface-containing mesh cells to the equilibrium state. The operation on cells instead of complex interface surfaces enables the use of fast graph algorithms without reconstruction. The model is validated for horizontal film condensation, and converges to exact solutions with increasing mesh resolution. Agreement with established results is demonstrated for smooth and wavy falling-film condensation.

Natural ventilation is an effective method to save energy required to condition buildings and to improve indoor air quality. Computational fluid dynamics (CFD) software was used to model single-sided buoyancy-driven natural ventilation in a single room with a heater and door. The velocity and temperature profiles at the doorway agreed fairly well with published literature that includes an experimental [1] and numerical study [2]. The CFD models predicted the neutral level with a difference of 1.5 % compared to experimental results. Using solutions at the doorway, heat transfer rates were calculated. More realistic situations were modeled by considering conduction through walls. The heat loss through the wall was measured and the solutions at the doorway were compared to the case with an adiabatic wall condition. The effect of heat transfer coefficients and the ambient temperature on heat loss through wall, room temperature, and airflow in the room were studied.

We have developed a process that uses both hierarchical and non-hierarchical clustering methods to mine data in tool catalogs. Principal component regression is used for quantifying the correlation between the predictor and criterion variables, and multiple regression analysis is used for creating an end-milling condition determinant matrix for each cluster. We fixed the outside diameter of the tool shape parameter as a constant trivial value and examined the correlation between the other tool shape parameters and the end-milling conditions. We thereby extracted valuable new knowledge hidden in trivial parameters and built a hypothesis in regards to data-mining effect. We found that cutting speed is the most important of the criterion variables and that the number of determination coefficient is no less important for determining prediction accuracy of end-milling condition decision equations. End-milling condition decision determinants derived from our data-mining process are important indicators for adjusting end-milling conditions on the basis of end-milling efficiency and tool life.
