On the acoustics of turbulent non-premixed flames

Gas turbines are clean, compact and eAEcient engines for electric power generation. They are used at a large scale to this end and are usually red with natural gas. A novel development is to re them with coal gas produced by a coal gasier. This opens ways to use the huge coal resources in a clean and eAEcient operation. As the combustion properties and conditions of coal gas are very dierent from those of natural gas, it is necessary to redesign the burners and combustors of the gas turbine. Because of the complexity of the burners and combustors in a gas turbine, many diAEculties have to be taken care of.
Energy Efficiency In Residential Buildings: A Case Study Of 1004 FederalHousing Authority Estate, Victoria Island, Lagos

Globally, energy consumption in buildings takes up the largest proportion of world‘s energy production. This consumption is more in developing countries including Nigeria and Least Developed economies than the developed worlds. Researches are therefore, currently been geared towards reducing energy consumption due to the global problem of insufficient energy needed to meet the demand and the attendant environmental issues associated with the production based largely on fossil burning. In Nigeria, consumption in buildings takes up about a third of the total electricity production with Lagos accounting for the larger percentage of the total energy production due to the fast rising population, teeming economic growth and increased rate of construction across the state. This paper thus investigates the energy consumption in residential buildings (1004 Federal Housing Authority Estate), in Lagos state. Survey analysis approach was adopted in this work. Field trips to the study area were conducted, measurements were taken and questionnaires were administered to occupants. The design features of the buildings were analyzed. The household equipments and the occupants were also taken into consideration. The work also analyze the present electric energy use for cooling and lighting typical residential buildings of upper income households in Lagos and the possible energy savings by adopting certain energy efficient features (in wall) in the case study building. The enveloped thermal transfer value (ETTV) equation was utilized to account for the quantity of heat taking into the building through the buildings envelop. Building wall of 200mm concrete thickness plastered with 13mm cement thickness in and out was used in the study. Result obtained indicates that doubling the thickness of external walls, reduces the cooling load of the building and hence reduces its total energy consumption. The total envelop energy of the building obtained was found to be 64.98W/m2, while 57.60 W/m2 was obtained when perlite was used in wall plastering in place of the cement with same thickness. Improvement of energy efficiency in residential buildings was also achieved through series of demonstration works carried out in the analysis using ETTV equation. The study established that the perlite plaster has a lower thermal transmittance value (U-value) when compare to that of cement hence a better energy reducing material option in building construction. The impact of ETTV on the energy consumption of residential buildings leading to a reduction in building heat load was also established in the study.

LEGISLATION AND REALITY: THE ARCHAEOLOGICAL EVIDENCE FOR SANITATION AND HOUSING QUALITY IN URBAN WORKERS’ HOUSING IN THE ANCOATS AREA OF MANCHESTER BETWEEN 1800 AND 1950

Abstract This paper will look at some of the excavated material for British urban workers’ housing, built and occupied during the period 1800 to 1950 in the Ancoats area of Manchester: Ancoats was notorious amongst contemporary writers and campaigners for its poor quality and overcrowded housing. This archaeological evidence has emerged as a result of developer-funded excavations and represents part of a growing body of data collected since 1990 from within many of the great industrial cities of Britain (Glasgow, London and Manchester), as well as excavations in the numerous smaller industrial manufacturing towns of the UK. In this study particular attention is given to the impact of national legislation, private acts and local by-laws aimed at improving industrialised living conditions and the build quality of 19th-century workers’ housing occupied into the 20th century. Using excavated examples from more than 50 houses within Ancoats, it will be argued that archaeology can provide a distinctive and unique view of urban domestic life in the 19th and first half of the 20th century, whilst demonstrating continuity in occupation patterns during this period. The evidence for urbanised, industrial living also compliments the more extensive archaeological studies of manufacturing industry from the period.
The Cambridge Handbook of Evolutionary Perspectives on Human Behavior

The transformative wave of Darwinian insight continues to expand throughout the human sciences. While still centered on evolution-focused fields such as evolutionary psychology, ethology, and human behavioral ecology, this insight has also influenced cognitive science, neuroscience, feminist discourse, sociocultural anthropology, media studies, and clinical psychology. This handbook’s goal is to amplify the wave by bringing together world-leading experts to provide a comprehensive and up-todate overview of evolution-oriented and influenced fields.While evolutionary psychology remains at the core of the collection, it also covers the history, current standing, debates, and future directions of the panoply of fields entering the Darwinian fold. As such, The Cambridge Handbook of Evolutionary Perspectives on Human Behavior is a valuable reference not just for evolutionary psychologists, but also for scholars and students from many fields who wish to see how the evolutionary perspective is relevant to their own work.
Moisture Susceptibility of Asphalt Mixtures with Known Field Performance

Moisture damage in asphalt mixtures refers to loss in strength and durability due to the presence of water. The level and the extent of moisture damage, also called moisture susceptibility, depend on environmental, construction, and pavement design factors; internal structure distribution; and the quality and type of materials used in the asphalt mixture. This study evaluates the moisture susceptibility of asphalt mixtures with known field performance using dynamic analysis and a crack growth model to characterize the asphalt mixtures and corresponding asphalt mastics. The model parameters were obtained from surface energy measurements, uniaxial dynamic testing for the asphalt mixtures, and dynamic shear testing for the asphalt mastics. Results showed good differentiation between the moisture-conditioned (wet) and unconditioned (dry) specimen behavior and provided a good correlation with the reported field performance of the asphalt mixtures.

A Simplified Unbalanced Control Strategy of PWM-VSC Based on Line Voltage Calculation

Presently, with regard to the research in control of three-phase PWM-VSC under unbalanced dips, most of the literatures gain the current commands through the phase voltages based on the PQ power theory and the control flow is complicate too much. This paper, based on the instantaneous power analysis of VSC grid-side, calculate the current commands through line voltages and use the line voltages instead of the phase voltages in the feedforward. Not only the equation of current commands calculation is simplified, but also avoids the transformation of line voltages to phase voltages. In addition, this method adopts neither PLL nor coordinate transformation, and current sequential extraction is eliminated by adopting the PR controller in the current loop. In the end, the simulation results testify the efficiency of the proposed scheme in resisting grid voltage harmonics and nullifying fluctuation of dc-voltage.
Stabil Angina Pektoris Hastalarında Tiyol/Disülfid Homeostazı Analizi

Objective: To investigate thiol/disulfide homeostasis in patients with stable angina pectoris. Materials and Methods: The study population consisted of 85 stable angina pectoris patients and 31 healthy volun-teers. To compare the thiol/disulfide values of the patients and controls, the newly developed analysis method was used by Erel and Neselioglu. Disulfide/total thiol, free thiol/total thiol and disulfide/free thiol values were calculated for both groups. Results: Disulfide, free thiol and total thiol values obtained in the study were; 18.00 µmol/L, 365.08 µmol/L, 401.10 µmol/L for the patient group and 9.67 µmol/L for the control group, 372.51 µmol/L, 391.85 µmol/L for the control group. It is the first time thiol/disulphide homeostasis in plasma was examined by new developed method in stable angina pectoris patients with this study. Disulfide, disulfide/free thiol and disulfide/total thiol values were significantly higher in the patient group compared to the control group. free thiol/total thiol levels were significantly lower in patients (p<0.001). Conclusion: Thiol and disulfide values can be seen at high levels in patients with stable angina pectoris, so thiol/ disulfide homeostasis may be an indicator for this disease.
The amino acid transporter OsAAP4 contributes to rice tillering and grain yield by regulating neutral amino acid transport through two splicing variants

Background Amino acids, which are transported by amino acid transporters, are the major forms of organic nitrogen utilized by higher plants. Among the 19 Amino Acid Permease transporters (AAPs) in rice, only a small number of these genes have been reported to influence rice growth and development. However, whether other OsAAPs are responsible for rice growth and development is unclear. Results In this study, we demonstrate that OsAAP4 promoter sequences are divergent between Indica and Japonica, with higher expression in the former, which produces more tillers and higher grain yield than does Japonica. Overexpression of two different splicing variants of OsAAP4 in Japonica ZH11 significantly increased rice tillering and grain yield as result of enhancing the neutral amino acid concentrations of Val, Pro, Thr and Leu. OsAAP4 RNA interference (Ri) and mutant lines displayed opposite trends. In addition, exogenous Val or Pro at 0.5 mM significantly promoted the bud outgrowth of lines overexpressing an OsAAP4a splicing variant compared with ZH11, and exogenous Val or Pro at 2.0 mM significantly enhanced the bud outgrowth of lines overexpressing splicing variant OsAAP4b compared with ZH11. Of note, the results of a protoplast amino acid-uptake assay showed that Val or Pro at different concentrations was specifically transported and accumulated in these overexpressing lines. Transcriptome analysis further demonstrated that OsAAP4 may affect nitrogen transport and metabolism, and auxin, cytokinin signaling in regulating rice tillering. Conclusion Our results suggested that OsAAP4 contributes to rice tiller and grain yield by regulating neutral amino acid transport through two different splicing variants and that OsAAP4 might have potential applications in rice breeding.
Enriched and depleted microbes at phyla level in humic acid (HA) fertilizer associated with delayed drought responses in maize

Background: Humic acid (HA) fertilizer was previously considered to be able to enlarge the effective absorption area of roots and promote plant root growth. While recent evidences suggested that certain root-associated microbes might be able to mitigate the negative responses of drought stress. In this study, we sought to explore abundance and diversity of root-associated bacterial communities under humic acid (HA) fertilizer and drought stress treatments. Results: We collected rhizospheres of three groups (HA, drought, and control) and microbiomes from bulk soil during flowering period in maize. We obtained the bacterial community for the V4 region of the 16S rRNA gene using Illumina Hiseq2500. By analyzing the sequencing data, we identified 40 bacteria phyla across samples. The abundance level of the 12 bacterial communities at phyla level are significantly different in the rhizosphere of the drought treated samples as compared to the controls, two of which, Actinobacteria and Bacteroidetes, were also significantly enriched (FC=1.79, adj.P=0.043) and depleted (FC=0.70, adj.P=0.086) in HA fertilizer treated samples. Conclusions: The results suggested that the delayed responses of plants to drought stress in HA fertilizer treated soils might be through supply a resource of substance to recruit drought-resistance microbiomes.
Improving Legacy Aircraft Systems Through Condition-Based Maintenance: An H-60 Case Study

Abstract : Condition-Based Maintenance (CBM) has been the focus of Department of Defense efforts to reduce the cost of maintaining weapons systems for nearly two decades. Through an investigation of the MH-60S helicopter, this paper uses a gap analysis framework to determine the value of increasing CBM usage. The Naval Aviation Maintenance Program (NAMP) has used scheduled inspections as the backbone of aviation maintenance since 1959. The most significant of these inspections is the phase cycle, which provides inspection of aircraft components based on flight hours. This study uses the MH-60S to conduct a capability gap analysis for CBM in naval aviation. Through the use of a JCIDS Capabilities Based Assessment, the capability gap between the CBM enabling IMD-HUMS and the NAMP phase cycle is determined. From this gap analysis, Earned Value Management (EVM) tools determine the value of closing the CBM capability gap between the phase maintenance and IMD-HUMS in terms of cost and safety. Finally, an alternative phase maintenance structure is proposed for MH-60S maintenance which leverages the CBM capabilities of the IMD-HUMS to reduce total lifecycle costs.

Comparison of nonlinear behavior of steel moment frames accompanied with RC shear walls or steel bracings

In this paper, the seismic behavior of dual structural systems in forms of steel moment‐resisting frames accompanied with reinforced concrete shear walls and steel moment‐resisting frames accompanied with concentrically braced frames, have been studied. The nonlinear behavior of the mentioned structural systems has been evaluated as, in earthquakes, structures usually enter into an inelastic behavior stage and, hence, the applied energy to the structures will be dissipated. As a result, some parameters such as ductility factor of structure (μ), over‐strength factor (Rs) and response modification factor (R) for the mentioned structures have been under assessment. To achieve these objectives, 30‐story buildings containing such structural systems were used to perform the pushover analyses having different load patterns. Analytical results show that the steel moment‐resisting frames accompanied with reinforced concrete shear walls system has higher ductility and response modification factor than the other one, and so, it is observed to achieve suitable seismic performance; using the first system can have more advantages than the second one.

Interferometric sensor based on the polarization-maintaining fibers

The interferometers composed of optical fibers are due to its high sensitivity capable of to measure various influences affecting the fiber. These influences may be bending or different sorts of fiber deformations, vibration, temperature, etc. In this case the vibration is the measured quantity, which is evaluated by analyzing the interference fringes representing changes in the fiber. Was used a Mach-Zehnder interferometer composed of the polarization maintaining elements. The polarization maintaining elements were used because of high sensitivity to polarization state inside the interferometer. The light was splitted into the two optical paths, where the first one is the reference fiber and it is separated from the actual phenomenon, and the second one is measuring fiber, which is directly exposed to vibration transmission from the underlying surface. The light source was narrowband DFB laser serating at a wavelength of 1550nm and as a detector an InGaAs PIN photodiode were used in this measurement. The electrical signal from the photodiode was amplified and fed into the measuring card. On the incoming signal the FFT was applied, which performs the transformation into the frequency domain and the results were further evaluated by software. We were evaluating the characteristic frequencies and their amplitude ratios. The frequency responses are unique for a given phenomenon, thus it is possible to identify recurring events by the characteristic frequencies and their amplitude ratios. The frequency range was limited by the properties of the used speaker, by the frequency characteristics of the filter in the amplifier and used resonant element. For the experiment evaluation the repeated impact of the various spherical objects on the surface board was performed and measured. The stability of amplitude and frequency and also the frequency range was verified in this measurement.
Analysis on Ergonomic Factor of Duties and Organizations towards Stress and Occupational Disease in Manufacturing Industry in Malaysia

Stress and occupational disease are the main issues that need to be addressed by the organization. Unconcerned organizations on this issue will provide a negative impact on employees and organizations and contributing to the increase in work accidents, employee absences problems, and the rise in non-infectious diseases at work. Previous studies show that safety and health problems including stress and occupational disease occur mainly in the manufacturing industry. This study will try to seek an answer whether the ergonomic factors of duties and organizations are related to the increase of stress and occupational disease in the manufacturing industry? A total of 843 respondents from few companies and states in Malaysia were reviewed and analysed. The findings of the study indicated that most group workers were unaware of ergonomics-related problems at work place. The research found that there was a significant relationship between the ergonomics factors of organizations and duties with stress and work-related disease in manufacturing industry. Therefore, several initiatives should be taken by the organizations to improve employee performance especially in relation to the implementation of ergonomics aspects and emphasize on safety and health campaign widely.
