Повний текст джерелаFats, oil and grease (FOG) is a significant constituent in numerous wastewaters such as those in dairy industry. The hydrolysis of FOG results in the production of long chain fatty acids (LCFA) which destabilize the anaerobic treatment process due to their physico-chemical and microbial toxicity effects. Harnessing the high methanogenic potential of FOG necessitates effective treatment of high LCFA loads, wherein the feasibility of LCFA treatment at low temperatures has been not investigated up to now. The aim of this thesis was to study the feasibility of high-rate anaerobic treatment of LCFA-rich wastewaters at low ambient temperatures using a dairy wastewater matrix.The screening of mesophilic inocula for treatment of mixed LCFA containing synthetic dairy wastewater (SDW) in batch studies showed that granular sludge inoculum achieved faster and higher methane yields (76-82% of theoretical yield) than the two municipal digestates (1-72%) at both 20 and 10°C. The LCFA degradative capacity in the granular sludge inoculum was attributed to the presence of β-oxidizing bacteria from the family Syntrophaceae (Syntrophus and uncultured taxa), the acetotrophic activity from Methanosaeta and putative syntrophic acetate oxidizing bacteria (SAOB). Continuous high-rate treatment of SDW was found to be feasible in expanded granular sludge bed (EGSB) reactors at 20°C (hydraulic retention time (HRT) 24 h, LCFA loading rate (OLR) 670 mgCOD-LCFA/L·d, 33% COD-LCFA) with a COD removal of 84–91% and methane yield of 44–51%. SDW feeding for longer than two months resulted in LCFA accumulation, which led to granular sludge flotation (36-57%) and disintegration. To counter the LCFA induced granular sludge disintegration and flotation, a novel reactor type, dynamic sludge chamber-fixed film (DSC-FF), was designed and achieved sCOD removal of 87-98% at HRTs from 12-72 h (LCFA loading rate 220-1333 mgCOD-LCFA/L·d) at 20°C. Moreover, even at the 12 h HRT, the unsaturated LCFAs (linoleate and oleate) were treated and only part of saturated LCFAs (stearate, palmitate) remained after treatment in the DSC-FF reactors. An increased methanogenic activity was established in the reactor sludges during reactor runs; evidenced by a higher acetotrophic activity in the granular sludge (from DSC), and a higher hydrogenotrophic activity in the biofilm (from FF) indicating development of distinct metabolic capabilities in the different reactor compartments. High throughput 16S rRNA sequencing showed that the relative abundance of the acetoclastic methanogen, Methanosaeta increased in EGSB reactors when fed with increased LCFA concentrations. The relative abundance of Methanosaeta increased also in the active microbiomes of granules (from DSC) and biofilm (from FF) during the 150-d reactor operation, demonstrating acetoclastic methanogenesis as the predominant methanogenesis pathway for SDW and LCFA degradation at 20°C. Microbial communities with a high β-oxidizing along with high methanogenic activity were developed during SDW treatment in DSC-FF reactors at 20°C. In DSC-FF reactors, the biofilm microbiome (from FF) had a prominent presence of the β-oxidizing bacteria Syntrophus and the hydrogenotrophic methanogen Methanospirillum; in comparison to the presence of the acetogenic bacteria - Syntrophobacter, Desulfobulbus, and Geobacter in the granular sludge microbiome, suggesting a role of these taxa at different trophic levels during LCFA degradation. In summary, this work demonstrated successful inoculum selection at low temperatures (10 and 20°C), and high-rate anaerobic LCFA degradation at 20°C using combined approaches of inoculum mixture and novel reactor design (here, DSC-FF). The key bacterial and archaeal taxa involved in the anaerobic conversion of LCFA to methane at 20°C were also deduced

Повний текст джерелаeffect of water temperature on cohesive soil erosion should be explored. The objectives of this study are to: determine the effect of water temperature on the erosion rates of clay; determine how erosion rates vary with clay mineralogy; and, explore the relationship between zeta potential and erosion rate. Samples of kaolinite- and montmorillonite-sand mixtures, and vermiculite-dominated soil were placed in the wall of a recirculating flume channel using a vertical sample orientation. Erosion rate was measured under a range of shear stresses (0.1-20 Pa) for a period of five minutes per shear stress at water temperatures of 12, 20, and 27�"C. The zeta potential was determined for each clay type at the three testing temperatures and compared to mean erosion rates. The kaolinite erosion rate doubled when the temperature increased from 12 to 20�"C, and erosion of vermiculite samples tripled when the temperature increased from 20 to 27�"C. The montmorillonite samples generally eroded through mechanical failure rather than fluvial erosion, and the limited fluvial erosion of the montmorillonite-sand mixture was not correlated with water temperature. The data suggest correlation between zeta potential and erosion rate; however, due to the small sample size (n=3), statistically significant correlation was not indicated. Research should continue to explore the influence of water temperature on cohesive soil erosion to better understand the influence of clay mineralogy. Due to the high degree of variability in cohesive soil erosion, multiple replications should be used in future work. The vertical sample orientation enabled discrimination between fluvial erosion and mass wasting and is recommended for future studies.

Повний текст джерелаGlobal climate change may result in rising temperatures. As a result, ecological health and the human use of rivers may be impacted. The hydrologic cycle, watershed hydrology, and in-stream hydraulics are dynamic systems, influenced by human activities, natural events, and climate. Although known drivers like precipitation and stream velocity govern sediment processes, the effect of water temperature on sediment transport remains unclear. In-stream sediment movement could lead to blocked harbors, flooding, and degradation of vulnerable fish habitat. To better understand how fluctuations in water temperature affect sediment dynamics, six transport models were analyzed on the Niobrara River, with water temperatures ranging 1° to 40° C. The results indicate that as water warms sediment transport decreases, according to an inverse, non-linear law, with the highest reduction at colder water temperatures. The results given here can help predict changes in sediment transport for rivers with similar characteristics at various water temperatures.

Повний текст джерелаJordens medeltemperatur beräknas öka med upp till 5 °C det här århundradet. För fiskar, som är ektotermer, är temperatur en av de viktigaste abiotiska faktorerna och påverkar dem på en mängd olika sätt, bland annat genom förändring av fysiologiska attribut, tidpunkter för steg i livscykeln och beteende. Lax har visats växa snabbare efter att ha blivit inkuberade i varmare vattentemperatur. En möjlig förklaring till det kan vara att en förhöjd inkuberingstemperatur orsakar en lägre metabolism. Det här projektet syftade till att undersöka om så är fallet. Ägg från lax inkuberades i tre olika temperaturförhållanden: naturliga temperaturförhållanden, förhöjd temperatur och en blandad temperaturbehandling, där ägg inkuberades i förhöjd temperatur till början av januari, varefter de utsattes för naturliga temperaturförhållanden. Gälslagsfrekvens, som fungerar som en indikator för metabolism, mättes på fisk från varje behandlingsgrupp, samt fiskarnas längd och vikt. Resultaten visade signifikant lägre gälslagsfrekvenser hos fiskarna från behandlingen med förhöjd temperatur, men inte hos fiskarna från behandlingen med blandad temperatur. Detta indikerar att en förhöjd inkuberingstemperatur orsakar en lägre metabolism hos lax, och att förändringen sker senare än tidiga januari. På grund av skillnader i storlek och livsstadier hos fiskarna från de olika grupperna är resultaten dock osäkra, vilket gör att ytterligare studier behövs. En lägre ämnesomsättning påverkar fiskars beteende. En uppföljning kan därför vara att studera fiskars överlevnad i det vilda i relation till deras metabolism.

Повний текст джерелаIncludes bibliographical references (p. 333-348).
Poly(ethylene terephthalate) is widely used for consumer products such as drawn fibers, stretched films, and soda bottles. Much of its commercial success lies in the fact that it crystallizes at large strains during warm deformation processing. The imparted crystallinity increases its stiffness and strength, improves its dimensional stability, and increases its density. The crystallization process and the stress-strain behavior above the glass transition depend strongly on temperature, strain rate, strain magnitude, and strain state. A robust constitutive model to accurately account for this stress-strain behavior in the processing regime is highly desirable in order to predict and computationally design warm deformation processes to achieve desired end product geometries and properties. This thesis aims to better understand the material behavior above the glass transition temperature in the processing regime. It examines the strain rate, strain state, and temperature dependent mechanical behavior of two polymers: PET and PETG, an amorphous non-crystallizing copolymer of PET, in order to isolate the effects of crystallization on the stress-strain behavior. Experiments over a wide range of temperatures and strain rates were performed in uniaxial and plane strain compression. A constitutive model of the observed rate and temperature dependent stress-strain behavior was then developed. The model represents the material's resistance to deformation with two parallel elements: an intermolecular resistance to flow and a resistance due to molecular network interactions.
(cont.) The model predicts the temperature and rate dependence of many stress-strain features of PET and PETG very well, including the initial modulus, flow stress, initial hardening modulus, and dramatic strain hardening. The modeling results indicate that the large strain hardening behavior of both materials can only be captured by including a critical orientation parameter to halt the molecular relaxation process once the network achieves a specific level of molecular orientation. This suggests that much of the strain hardening in PET is due to molecular orientation and not to strain-induced crystallization. An example blow molding process is simulated to demonstrate the industrial applicability of the proposed model.

Повний текст джерелаThe objective of the present study was to evaluate and quantify the effect of artificial shade given by different types of roofing materials on the physiology, behavior and development of dairy heifers in a pasture environment. The present study took place from January 8, 2007 to April 30, 2007. The experimental area was divided into 16 equal, adjacent plots with 84 m2. Three roofing treatments (fiber-cement roofing tiles without amianthus, galvanized roofing tiles and 80% polypropylene screen) were compared to a control (no shade). Shelter structures had no lateral walls and measured 2m x 4m x 4m height (4m² shaded per animal). Animals consisted of 16 Holstein heifers and 16 Holstein x Jersey heifers with initial age and weight being 17.2 ± 5.6 months and 265.3 ± 66.9 kg, respectively. Animals were equally distributed among the treatments according to weight and age. At night, heifers were kept in fields with Pennisetum purpureum, also known as elephant grass. After 9:00 am, animals were taken to the experimental plots. Black globe thermometer temperature (tbg) was measured using a mini-datalogger connected to a black globe. Values were then used to calculate Radiant Thermic Load (RTL) and Black Globe Humidity Index (BGHI) of each plot. Meteorological variables were obtained from the agricultural-meteorological post at the ESALQ/USP. Respiration rate (RR), rectal temperature (RT) and skin temperature (ST) were registered weekly. Behavioral observations were recorded every other day using the focal method. Animals were weighed monthly. Environmental conditions during the research period were characterized as stressful for the heifers. Physical analysis of the material (tbg, RTL and BGHI) indicated the roofing treatments to be significantly different (P<0.05), with the fiber-cement roofing tiles without amianthus to be the most comfortable regarding temperature, followed by the galvanized roofing tiles and the 80% polypropylene screens. Respiration rate was lower under the fiber-cement roofing tiles (P<0.05) and similar under the galvanized tiles and polypropylene screen (P>0.05). RR values were lower under the fiber-cement tiles (P<0.05) and similar under the galvanized roofing tiles and polypropylene screen (P>0.05). There were no significant differences in RT values among treatments; however, a difference was found among data collection times. Concerning ST, fiber-cement tiles were significantly different from the control (P<0.05). On the other hand, there were no significant differences regarding ST among the other treatments (P>0.05). RR presented the most immediate response to environmental alterations. RT presented correlation with RR and ST. No behavioral alterations were observed among the treatments. Daily behavior followed known bovine patterns. Weight gain was not altered by the treatments. A cost analysis indicated fibercement roofing tiles to be better for shelter construction. The present study also indicated improved heifer thermal well-being; however, no effective gains could be determined from shade use.

Повний текст джерелаThe purpose of this study is the development of an affordable computer-based electrocardiogram, heart rate and temperature monitoring system, that would complement those that are available on the market and contribute to the reduction of the shortage of these medical instruments in South African hospitals and clinics. Electrocardiogram (ECG) refers to the graph that results from time versus voltage in a patient's chest. It reflects the rhythmic activity of the heart. For this reason the electrocardiogram has a diagnostic value that can be used by medical personnel to examine the biological (hence, clinical) behavior of the heart. The electrocardiogram can also be used to get the heart rate. This thesis explained how to acquire ECG signals from the patient and also how to achieve a cheaper way of providing galvanic isolation, which is required for sensors that are attached to the human body. It also explains computer interfacing using the parallel port and computer-based processing of these ECG signals to determine the instantaneous value of the heart rate and also to reduce the interference that contaminates these signals. In reducing interference, the performance of traditional IIR notch and adaptive filters, as noise cancelers, has been analyzed and compared. Least Mean Squares (LMS) and Normalized Least Mean Squares (NLMS) algorithms are the two algorithms that were considered in this study for adaptive noise canceling and their performance is evaluated and is compared based on their convergence rate, complexity and noise reduction.

Climate change in recent years is a formidable challenge for Aquaculture. Macrobrachium rosenbergii is a high-value aquatic product. It is a poikilotherm, so the change in ambient temperature has a direct impact on the physiological status of Macrobrachium rosenbergii, this is also related to the optimal temperature range for it to survive and the tolerance limits. This study will measure the heart rate and the swinging rate of scaphognathite in the freely moving Macrobrachium rosenbergii at different temperature ranges, to understand the relationship between temperature changes and their physiological regulation. The ECG signals were get with an electrode embedded in the posterior edge of the heart and measuring the swing of scaphognathite by using an electrode embedded in the operculum. The experiment was divided into two parts, namely the temperature rising experiment and the cooling experiment. The Macrobrachium rosenbergii continued to heat up at 23 ° C and died (about 38 ° C), and after 28 ° C rest, the temperature was continuously cooled to death (about 10 ° C). The results showed that the heart rate and respiration rate change was linearly correlated with the increase/decrease of temperature. The limitation of heart rate was the rate at 33°C degrees and the respiration rate was the rate at 37°C degrees; The extreme low lethal temperature is 10°C degrees for heart rate. The high temperature is estimated because the heart rate increases to the limit and cannot effectively supply the blood required for metabolism, resulting in death at high temperatures. Low temperatures may result in systemic hypoxia and death due to slow heart rate and breathing.

With the advancement of integrated circuit technology, increasing number of electronic instruments are designed with high circuit density. In this situation, overheat is a very important issue, so we need a temperature sensor for thermal management. In this thesis, we proposed a high conversion rate time-domain temperature sensor with temperature compensated self-oscillation, which uses a time-amplified temperature-dependent delay line to perform the delay. Compared with the traditional temperature delay line, the time-amplified temperature-dependent delay line can greatly reduce the power consumption and the number of transistors used. We also added a temperature compensated oscillator to provide a high-frequency signal for the temperature sensor and to reduce the costs of the instruments and their noise contribution to the circuit. This chip has been implemented in the TSMC 0.18μm 1P6M CMOS technology, and the supply voltage is 1.2 V. The oscillator frequency is 602 MHz. At a conversion rate of 146 kHz, the energy consumption per conversion is 9.83 nJ. The core area of chip is 0.149 mm2. The temperature measurement range is from 20 to 80 oC with a resolution of 0.48 oC/bit and a measurement error between -0.61 and 0.46 oC. Based on the simulation results, the oscillation frequency is close to the required system frequency. During the actual measurement, the temperature sensor had high conversion rate and resolution and outputted correct digital codes, making it suitable for thermal management in SoCs.
