Abstract:
Abstract This study examines the local memory of atmospheric and oceanic changes associated with a tropical cyclone (TC). The memory is quantified through anomalous maximum potential intensity (MPI) evolution for 20 days prior to the arrival of a TC through 60 days after the TC passage. The local MPI weakens and is not restored to the evolving climatology until well after the TC has departed. Stabilization occurs through warming of the atmosphere and cooling of the ocean surface on different time scales. The time scale of MPI stabilization following TC passage is approximately 30–35 days for a tropical storm to 50–60 days for a category 3–5 hurricane, with significant storm-specific and basin-specific variability. The atmospheric stabilization (warming with respect to SST) begins with TC arrival and continues for approximately 7–10 days after passage, when the troposphere cools below normal. The rewarming of SST and the subsequent rewarming of the atmosphere occurs within approximately 35 days for all intensities, despite a positive (weakened) MPI anomaly through two months. This suggests that the atmosphere retains anomalous warmth beyond what can be attributable to sensible heating from the rewarmed SST. The maintenance of a positive MPI anomaly beyond 35 days is thus attributed to a feedback on larger scales that requires considerable further research. A TC’s passage through a region does not always lead to a weakening of the MPI. In regions poleward of the sharp SST gradient, the MPI one month after TC passage is often several millibars stronger than climatology. There are also mesoscale regions of destabilization one month after TC passage that may result partially from salinity changes driven by oceanic mixing as well as changes in precipitation and evaporation.

Abstract:
Background It is unknown whether the waist circumference (WC) or the waist-to-hip ratio (WHR) is a better predictor of cardiovascular risk factors at different ages. Objective To compare WC and WHR as predictors of cardiovascular risk factors and to determine the prevalence of some cardiovascular risk factors in overweight and obese adult women at different ages. Methods In this clinical cross-sectional study, 714 overweight and obese women aged 20 to 70 years who were referred to two nutrition clinics in Sistan and Baluchestan province, Islamic Republic of Iran, were studied. The subjects were classified into three groups, 20 to < 35, 35 to < 50, and > or = 50 years of age. Anthropometric indices were measured according to the standard protocol. Total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), and TC/HDL-C ratios were enzymatically determined. Results Older subjects (> or = 50 years old) had significantly higher values of body mass index (BMI), WC, TC, TG, and LDL-C than those in the two younger age classes. The prevalence rates of obesity, high WC, high WHR, high TC, high TG, high LDL-C, and high TC/HDL-C ratios were higher in the older subjects. After adjustment for age and BMI, multiple linear regression showed that WC was significantly related to TC and TG in the 20- to < 35-year-old group and to TG in the 35- to < 50-year-old group. In the older participants, WHR was significantly related to TG. Conclusions The prevalence of cardiovascular risk factors increases with age. In clinical practice, WC is a better index for predicting some cardiovascular risk factors in younger and middle-aged women; however, for older women, WHR is better.

ABSTRACT Different properties of substrates based on tung compost (TC), carbonized rice husk (CRH) and earthworm humus (H) were analyzed, besides the effect of the formulations on the production of lettuce seedlings, cv. Veneranda. The experiment was carried out in Pelotas, Rio Grande do Sul State, Brazil, from December 2012 to February 2013, in a greenhouse, using completely randomized design with seven treatments and three replications. The used substrates were formulated on a volume basis: T1= commercial substrate S10® (control); T2= 90% carbonized rice husk (CRH) + 10% humus (H); T3= 75% CRH + 15% tung compost (TC) + 10% H; T4= 55% CRH + 35% TC + 10% H; T5= 35% CRH + 55% TC + 10% H; T6= 15% CRH + 75% TC + 10% H; T7= 90% TC + 10% H. Seedlings were produced in polystyrene trays with 200 cells, being evaluated 35 days after sowing. The substrate with larger proportion of CRH (T2 with 90% CRH) showed suitable dry density (DD) and total porosity (TP), high pH and aeration space (AS), low easily available water (EAW), electric conductivity (EC), and nutrient content, constituting an inert substrate, not being indicated as substrate due to the lower development of the seedlings. Using 15% TC, an increase was noticed in DD, AEW, EC and nutrients and, a decrease in TP, AS and pH due to, mainly, the size of tung compost particles, which accommodated themselves and altered physical and chemical properties of the substrates. Substrates with 90% and 75% TC (T7 and T6) provided the greatest shoot length, fresh and dry shoot mass and leaf area for lettuce seedlings due to higher nutrient content, also considering physical and chemical properties of these substrates. Pure CRH is not indicated to be used as substrate, but mixed with tung compost (T6), it provides high quality seedlings. Tung compost was effective in producing lettuce seedlings, since the composting is able to eliminate phytotoxic substances from this material which can hinder the seedling growth.

Abstract Context/Objective Increases of thyroid cancer (TC) incidence emerged in the past several decades in several countries. This study aimed to estimate time trends of TC incidence in India and the proportion of TC cases potentially attributable to overdiagnosis by sex, age, and area. Design TC cases aged 0 to 74 years reported to Indian cancer registries during 2006 through 2014 were included. Age-standardized incidence rates (ASR) and TC overdiagnosis were estimated by sex, period, age, and area. Results Between 2006-2008 and 2012-2014, the ASRs for TC in India increased from 2.5 to 3.5/100,000 women (+37%) and from 1.0 to 1.3/100,000 men (+27%). However, up to a 10-fold difference was found among regions in both sexes. Highest ASRs emerged in Thiruvananthapuram (14.6/100,000 women and 4.1/100,000 men in 2012-2014), with 93% increase in women and 64% in men compared with 2006-2008. No evidence of overdiagnosis was found in Indian men. Conversely, overdiagnosis accounted for 51% of TC in Indian women: 74% in those aged &lt; 35 years, 50% at ages 35 to 54 years, and 30% at ages 55 to 64 years. In particular, 80% of TC overdiagnosis in women emerged in Thiruvananthapuram, whereas none or limited evidence of overdiagnosis emerged in Kamrup, Dibrugarh, Bhopal, or Sikkim. Conclusions Relatively high and increasing TC ASRs emerged in Indian regions where better access to health care was reported. In India, as elsewhere, new strategies are needed to discourage opportunistic screening practice, particularly in young women, and to avoid unnecessary and expensive treatments. Present results may serve as a warning also for other transitioning countries.

Abstract:
SUMMARY This study aimed to evaluate biometric viscera and blood parameters of quails at 14 and 35 days of age, supplemented with different levels of inorganic selenium and vitamin E. A completely randomized design was used in a 4×4 factorial scheme (inorganic Se = 0.1125, 0.2250, 0.3375 and 0.4500 mg/kg diet x VE = 10, 23, 36 and 49 IU/kg feed). In the 0-14 days experiment, 2,400 newborn quail were used, distributed in 16 treatments and three replications of 50 birds each. In the 14-35 days experiment, 1,680 14 day-old quails were used with same treatments and three replicates of 35 birds each. At 14 days, the relative spleen weights (P=0.0203) increased linearly as a function of the VE level, while at 35 days, the relative weight of the bursa (P=0.0390) increased linearly as a function of Se concentration. At 14 days, there was a vitamin x mineral interaction (p=0.0097) affecting total cholesterol (TC), and a quadratic effect (P = 0.0138) related to Se and linear reduction levels (P=0.0275) as a function of VE. At 35 days, the TC concentrations (P=0.0055) and triglycerides (TG, P = 0.0220) showed a quadratic effect for Se. The linear increase in spleen weight and bursa after 14 and 35 days respectively suggests an improved immune response as a function of VE and Se supplementation. To achieve the lowest concentration of TC and TG at 35 days of age, supplementation of 0.26 and 0.29 mg/Se/kg/feed, respectively, is recommended.

Abstract:
It is thought that strong electron correlation in an insulating parent phase would enhance a critical temperature (Tc) of superconductivity in a doped phase via enhancement of the binding energy of a Cooper pair as known in high-Tc cuprates. To induce a superconductor transition in an insulating phase, injection of a high density of carriers is needed (e.g., by impurity doping). An electric double-layer transistor (EDLT) with an ionic liquid gate insulator enables such a field-induced transition to be investigated and is expected to result in a high Tc because it is free from deterioration in structure and carrier transport that are in general caused by conventional carrier doping (e.g., chemical substitution). Here, for insulating epitaxial thin films (∼10 nm thick) of FeSe, we report a high Tc of 35 K, which is 4× higher than that of bulk FeSe, using an EDLT under application of a gate bias of +5.5 V. Hall effect measurements under the gate bias suggest that highly accumulated electron carrier in the channel, whose area density is estimated to be 1.4 × 1015 cm–2 (the average volume density of 1.7 × 1021 cm–3), is the origin of the high-Tc superconductivity. This result demonstrates that EDLTs are useful tools to explore the ultimate Tc for insulating parent materials.

Abstract:

Detta examensarbete är ett utvecklingsarbete av demonstrationsutrustning för enkel visning av fördelarna med M2M-tekniken vid insamling av mätdata och automatisk övervakning. Arbetet består av en praktisk del, som utgörs av demonstrationsväskan, och en mer teoretisk del, som utgörs av demonstrationsprogrammet.

Programmet har utvecklats till att med ett mätkort kopplat till en PC samla in mätvärden (spänningar), dessa skickas sedan som ett SMS med ett GSM-modem till en mottagare. Mottagaren kan vara en serviceman som vill ha felmeddelanden från utrustning inom dennes ansvarsområde, mottagaren kan även vara en server som rymmer en databas vilken används för att spara viktiga mätvärden för längre tid, t.ex. loggning av elförbrukning hos något kraftbolags kund.

Det hela har alltså resulterat i ett färdigt och väl fungerande program, som utför just det som är uppdraget ovan. Mätresultatenhar tillräcklig noggrannhet för detta uppdrag om att demonstrera fördelarna med M2M-tekniken, och mätresultatet kommer även fram till mottagaren i sin rätta form.

Detta betyder att M2M Communication AB nu kan demonstrera vinsten med M2M-tekniken för potentiell kund på ett enkelt och förklarande sätt. Integrerat i demonstrationsutrustningen har nu också företaget fått en enkel och självklar utrusning för att i praktiken se hur nya givare och annan utrusning fungerar ihop med ComHost 300 som är företagets primära produkt.


The goal with this master thesis is to develop a simple equipment to show the advantage of using M2M-technic when collect measured data and when using automatic monitoring of alarm and sensors. The thesis is divided in two parts, a practical part that corresponds to a case with sensors and equipment. The case is used to collect measure data to be used when demonstrating the theoretical part, which corresponds to the software program. The software program is developed to measure voltage with the data acquisition card, and then send them as a SMS text message via the GSM network. For this tasks the software also have to control the GSM-modem. This text message is either sent to a computer for logging in a database, or to the service department who owns the equipment measured.

This work has ended up in well function software that can be installed on a PC-system with a Windows 2000(tm) operation system. The accuracy on the measured data is good enough for the task to demonstrate the function of the M2M-technic. The text message is also arrive to the receiver as expected.

The result of this master thesis ends up giving the company M2M Communication AB the possibility to demonstrate the M2M-technic on a simple and explaining manner for a potential customer. Integrated in the new equipment the company also has been given a possibility to test new sensors and signal sources in a real world M2M test.

We researched aging of the LRB (Lead Rubber Bearing) installed in a base-isolated building which was constructed 15 years ago. The hardness of the cover rubber and the height were measured for 35 LRBs which were installed in the building. The compression test and combined compression shear test with monitor samples and actually installed LRB were performed to search changes in their hysteresis characteristics. The monitor samples were composed of 4 LRBs and 1 RB. Main results obtained were as follows: 1) The LRBs installed in the TC building crept approximately 1 (mm) during 15 years and did not changed during last 5 years. 2) The hardness of the cover rubber did not change against that of 15 years ago. 3) From the testing of the monitor samples, the compression stiffness increased approximately 17% and the shear stiffness increased approximately 5%, however the yield force changed quite a little during 15 years on average. As a result, the suitability of the design specifications of the LRB was confirmed.

Abstract:
Abstract Supercritical compressed air energy storage system requires high turbine efficiency over a wide working range at both the design-point and off-design point. The operating range of the turbine is often limited by the occurrence of flow instability, such as distinct vortex and load deterioration. In specific situations, the development of aerodynamic instabilities at low inlet pressure operating conditions can lead to lower turbine efficiency, even lead to turbine choke, limiting the wide operating range of the turbine. Specifically, the high-pressure stage turbine of the expander, namely the first stage turbine, will not only bears a sharp change of inlet pressure but also experiences the maximum and variable pressure drop. In this paper, Real Gas Property (RGP) file for supercritical air is used for simulations. The CFD method and RGP file are validated by the turbine in the NASA report. A detailed 3D CFD analysis is performed for the preliminary designed first stage turbine under variable inlet pressure. With the purpose of improving the aerodynamic performance of the first stage turbine under extreme working conditions, a series of simulations are conducted to examine the effects of the IGV parameters (i.e. different types of IGVs, the nozzle-impeller radial gap distance and the nozzle blade installation angle) and blade thickness, which led to the optimization in overall turbine stability. The results show that IGV TC-2P have good aerodynamic performance, and the matched rotor can achieve an isentropic efficiency of 80% under off-design working conditions. The optimal blade installation angle blade is 35°. And there exists an optimal nozzle-impeller radial gap distance Δr. The turbine efficiency obtains a maximum value at Δr = 5 mm. In all cases for blade thickness, the different configurations have a significant change in inlet total pressure of 4.5 MPa compared to the design pressure of 7 MPa. The maximum efficiency is reached at the ellipse ratio is 1:1 for Case-2. The results of the optimal IGV TC-2P performance optimization is essential to improve the isentropic efficiency at low inlet pressure.

Abstract:
Abstract Thrust collars (TCs) are bearing elements used in geared machinery that transmit axial loads from one shaft to another. TCs are primarily used in integrally geared compressors (IGCs), but are also found in gearboxes and marine propulsion applications. TCs are hydrodynamic elements featuring a converging-diverging wedge to generate a pressure field that reacts axial loads. Accurate modeling requires knowledge of the film characteristics such as cavitation, turbulence, and air ingestion, all of which reduce load capacity. Current models in the literature do not include mass-conserving cavitation algorithms or turbulent flow. The following paper introduces a new test rig that optically characterizes the thin film region of a thrust collar. The test rig geometries, speeds, and loads match those typically seen in IGC applications. The test rig utilizes a transparent acrylic window in conjunction with a high-speed camera to obtain high-speed images of the oil film. Images are filtered and averaged to obtain areas of interest in the oil film. Cavitation and turbulence areas are captured for pinion speeds of 2.5, 5, and 7.5 krpm, and axial loads of 0.5, 1, and 1.5 kN. Cavitation occurs in the diverging (upper) region of the TC and appears at pinion speeds over 5,000 rpm, but does not change in shape after that speed. The cavitation is independent of applied load. Turbulence at the inlet region (bottom) occurs at all speeds, but increases to almost 35% of the total area at the highest speed. This paper also presents a finite element (FE) model that includes predictions for the static characteristics of the TC, specifically the cavitation area. The cavitation modeling uses an iterative Elord’s method, which conserves mass. The model predicts a similar cavitation area for all speeds and loads. A computation fluid dynamics (CFD) study predicts a similar cavitation area, and pressure field to the FE model. The CFD model predicts turbulence in the lower region that increases for increasing spin speed, which matches the experimental results. The CFD model tends to underpredict the turbulence area when compared to the experiments. As IGCs move into novel application areas to satisfy new needs, the increase in efficiency and capacity comes at a cost of more load and higher speed requirements on the TCs. This work will help original equipment manufacturers model TCs more accurately to ensure safe and efficient operation.

Abstract:
An experiment study is conducted to investigate the effect of transverse power distribution on the Onset of Nucleate Boiling (ONB) through a one-side heated narrow rectangular channel. Two test section are used to perform the experiment; uniform and non-uniform heated suction. The demineralized water is flowing in upward direction through the coolant channel with a thickness of 2.35 mm, a width of 54 mm, and a length of 300 mm. The experiment is carried out under different thermal power (0.5 kW – 6.5 kW) for the both test section. As well as, a wide variety of inlet subcooling and flow velocity are used as; 65−35 °C and 0.1–1.0 m/s, respectively. The wall temperature distribution of the heated plate is measured by 10 TCs for the uniformly heated test section, and 20 TC for the non-uniformly heated section. On the other hand, the ONB location is visualized via high speed camera, in which the ONB occurs near the edges for the non-uniformly heated section and occurs at the center of the heated surface for the uniformly power distribution. The results of the ONB heat flux and temperature in the non-uniformly heated section are compared against the one in the uniformly heated power. The results show the variety of the ONB location, ONB heat flux with the different power distribution. With the increase of the power, the ONB is shifted toward the inlet. On the other hand, the ONB for the non-uniform power distribution occurs near the edges at power lower than that the one in the uniformly power distribution. Also, the results are compared against the available correlations, such as Bergles and Rohsenow (1965), Jens and Lottes (1951), and Thom et al. (1965), as well as other experimental results done by several research institutes.
