Evaluating appropriate maximum holding times for private well water samples

Privately maintained groundwater wells are often located at a great distance from laboratories, creating a barrier to bacteriological testing (a necessity for determining drinking water potability). Extending the acceptable holding time between testing and collection could potentially diminish this barrier. Using seven Escherichia coli strains isolated from private well waters, the acceptability of Ontario's current allowable sample maximum holding time (48 h) was compared with time of collection. Additionally, the acceptability of extending the holding time from 48 h to 72 h was investigated. All analyses were performed using noninferiority statistical approaches to determine if later holding times had no meaningful difference in bacterial growth (determined by colony forming unit enumeration). All strains did not statistically decrease below the acceptable 10% difference during the two time periods. However, variations in the survival rates of isolates were observed, suggesting that a risk management ap.
Two-dimensional simulation of orientation effects in self-aligned GaAs MESFETs

The stress-induced orientation effects in self-aligned GaAs MESFETs were studied using a two-dimensional analysis. Devices oriented along different crystal directions, with different gate lengths, and under different stress conditions were studied. It was found that the piezoelectric effect caused by the surface stress plays a very important role in the device characteristics of short-channel self-aligned MESFETs. Structure parameters such as lateral spreading of N/sup +/ ions and p-type impurity concentration in the substrate were found to have great influence on the short-channel effect as well as the orientation effect. The short-channel effects can be suppressed and the device performance improved if the devices are oriented in the right direction and the structure of the devices and the thickness of the surface dielectric layer are properly chosen. >
Optimal Instantaneous Unit Hydrograph from Multistorm Data

An optimization method for estimating an optimal smooth instantaneous unit hydrograph (IUH) from multistorm data taken simultaneously is proposed. A gamma IUH is used for representing the analytical IUH. The parameters of the analytical IUH are optimized. The method avoids oscillations in the tail end of IUH. It automatically takes care of the volume and nonnegativity constraints. The application of the method is illustrated through examples. The new method reliably estimates the optimal IUH.

Effect of Gasoline and Paint Products on Cardiac Markers and Blood Glucose

Hydrocarbons (benzene, toluene, ethyl benzene and xylene (BTEX) found in gasoline and organic solvents are ubiquitous in the environment, and are known to have toxic effects in human system. This study therefore investigated in workers occupationally exposed to gasoline and paint products, the levels of glucose, apoprotein-B100 and cardiac troponin-I as indices of diabetes and cardiac functions. A total of 162 subjects were recruited for this study; (56 gasoline pump attendants and 56 paint factory workers) and 50 subjects as control. Sample collected were used for the estimation of Fasting blood sugar (FBS) using spectrophotometer; Apoprotein-B100 and troponin-I using Enzyme linked immunosorbent assay (ELISA) techniques. APOB-100 was significantly higher (P<0.05) in the gasoline workers (2.30±0.85) than in the paint workers (1.86±1.12) and control subjects (1.90±0.77). The mean Troponin-I level was significantly higher in the gasoline workers (10.35±4.87) than in the paint workers (4.65±2.71) and in control group (8.14±5.13) (P=0.000). The mean glucose level, body mass index, systolic and diastolic blood pressures were of non-significant difference (P>0.05) across the groups. The correlation coefficient between Apo-B100 and Troponin-I with the duration of exposures for gasoline and paint products showed non-significant negative correlations (P>0.05) respectively. Our result finding is suggestive of significant alterations in the serum levels of Apo-B100 and Troponin-I as evidently shown by the significant elevations of APO-B100 and Troponin-I in workers exposed to both gasoline and paint products than in control subjects. Thus, workers exposed to gasoline and paint products could be predisposed to cardiovascular diseases at later age.
Numerical simulation of PD activity in a spherical cavity embedded in the stator winding insulation of an inverter-fed induction motor

As shown in recent papers, partial discharge activity has a fundamental role in the premature failure of electrical insulation of machine stator windings fed by PWM inverters. The existence of partial discharges can be easily explained if we take into account that the presence of microvoids inside a composite insulation is essentially unavoidable. Since such microcavities are filled with a gas whose permittivity is generally several times lower than the permittivity of the surrounding dielectric, the electric field in such occlusions can be much higher than the local expected average stress. The aim of the present paper is to study the influence of the different voltage waveshapes impinging on the motor on the partial discharge activity in a spherical cavity embedded in the stator winding electrical insulation. The numerical study is carried out by using a multiconductor transmission line model for the evaluation of the potential distribution inside the machine and a PD simulation model for the evaluation of the possible ensuing PD activity.
Oil palm fruit bunch grading system using red, green and blue digital number.

This research deals with the ripeness grading of oil palm fruit bunches. The current practice in the oil palm mills is to grade the oil palm bunches manually using human graders. This method is subjective and subject to disputes. In this research, we developed an automated grading system for oil palm bunches using the RGB color model. This grading system was developed to distinguish between the three different categories of oil palm fruit bunches. The maturity or color ripening index was based on different color intensity. Our grading system employs a computer and camera to analyze and interpret images equivalent to the human eye and brain. The colors namely Red, Green and Blue (RGB) of the palm oil fruit bunch were investigated using this grading system. The computer program developed and used the mean color intensity to differentiate between the different color and ripeness of the fruits such as oil palm FFB. The program results showed that the ripeness of fruit bunch could be differentiated between different categories of fruit bunches based on RGB intensity.
Reviving the Search for Optimal Tetrahedralizations

This paper revisits a local mesh modiﬁcation method known as the Small Polyhedron Reconnection (SPR) [1]. The core of the SPR operation is a branch and bound algorithm which computes the best 3D triangulation (tetrahedralization) of a polyhedron through an eﬃcient exploration of the set of all its triangulations. The search can accomodate for additional geometric constraints and will inevitably ﬁnd the highest quality triangulation of the polyhedron if a triangulation exists. This paper focuses on the design of an optimized SPR operator and its application to improving the quality of ﬁnite element meshes. Compared to the original algorithm, a speed-up of 10 million is obtained by changing the heuristics determining the search space exploration order. This enables the integration of the SPR operator into standard mesh generation procedures. We show quality improvements obtained by applying this operation to meshes that have already been optimized using smoothing and edge removal techniques.
A novel method to compute the closest unstable equilibrium point for transient stability region estimate in power systems

It is well known that the threat of instability governs most aspects of modern power system operation. This being the case, any improvements made in determining the imminence of an unstable condition, or controlling it has great benefits to modern interconnected power networks. In this paper, we first review the well-known closest unstable equilibrium point (closest UEP) method for transient stability region estimate. One key step involved in the closest UEP method is to search for the closest UEP. This paper presents a new search algorithm for the closest UEP so that one can avoid the fractal nature of the Newton-Raphson method which is usually used in the closest UEP method. Finally, we applied the algorithm to three-machine system and obtained satisfactory simulation results.

THE FREE VIBRATION OF LONG-SPAN TRANSMISSION LINE CONDUCTORS WITH DAMPERS

Abstract The free vibration of a transmission line conductor equipped with a number of Stockbridge dampers is modelled by a differential equation of motion of a tensioned beam acted on by concentrated frequency dependent forces, and an exact solution is obtained using integral transformation. By evaluation through aeolian vibration level computation, the expressions obtained for the mode shapes can be easily used to predict accurately the overall strains of lines in operation or under design. Numerical examples show that the usual sinusoidal mode shapes can be significantly distorted by the dampers to give rise to dangerous strains.
Woman, Man, Society and Sex: How Pre-Service Teachers Perceive Basic Gender Concepts?

The aim of the study is to reveal Turkish pre-service teachers' gender perceptions. For this, cognitive structures of pre-service teachers were analysed with minds maps created with the word association test (WAT) and their mental models were analysed by drawing. In this context, a holistic single case study was adopted depending on the purpose of the research and the data collection process. According to the findings obtained from the WAT, it was determined that the cognitive structures of pre-service teachers were built on the sex, society and woman, and the man was in a weakly related in the cognitive structure. On drawing analysis, it was seen that most of the pre-service teachers depicted man and woman with visuals reflecting traditional stereotypes. On the other hand, visuals reflecting an egalitarian and contemporary perspective. In the light of both analysis results, Turkish teacher education curricula were discussed and specific suggestions were presented.

Playing the ".ac" card in noise analysis of RSFQ circuits

Noise-induced bit error rate (BER) is an important design constraint for RSFQ circuits. No method, however, has been reported to calculate the BER of real, multi-junction RSFQ gates. We report such a method that requires only the operating margins and the root-mean-square noise current of the device in question. Noise current is determined using the ". ac" analysis card built into SPICE circuit simulators. As usual, operating margins are also determined using SPICE. These quantities determine BER via the error function, as is appropriate for threshold dynamics. The method is general enough to be applied to any RSFQ gate and even exotic circuits such as those that use passive microstrip signal propagation. Comparison to experimental data indicates that BER in RSFQ circuits does indeed arise strictly from thermal noise.
Assessing design by design: progress report 1

This paper is a first progress report of a National Science Foundation Assessment of Student Achievement project designed to develop and test assessments of the ABET student learning outcome of "an ability to design a system, component or process to meet desired needs. " The overall strategy is to use the research on the nature and acquisition of expertise to guide the choice of assessment tools and then to embed those assessments in a course based continuous improvement loop to evaluate which work best to improve those learning outcomes. So far, the project, which began in June 2002, has yielded prototypes of four assessments and a precursor to a fifth. One of those tools, a multiple-choice test of declarative understanding of design process principles, has been refined and the current version (the third of four versions) exhibits both reliability and validity.

The Impact of Hotel Room Colors on Affective Responses, Attitude, and Booking Intention

ABSTRACT Drawing on color psychology, two scenario-based experiments were conducted to investigate how hotel room colors affect consumer’s affective responses, attitude, and booking intention. The moderating effects of trip purpose and consumer characteristic (environmental consciousness) were also examined. In Study 1, consumers demonstrated more positive attitude and higher booking intention for a hotel room that featured the cool color scheme than a room that featured the warm color scheme. Meanwhile, feeling of pleasure mediated the effect of hotel room color on booking intention. In Study 2, we found that consumers who are more environmental conscious demonstrated more positive attitude and higher booking intention for a hotel room featuring the green color than a room featuring the red color. Implications and future research are discussed.
The effect of dietary supplementation of ensiled pomegranate by-products on growth performance, nutrient digestibility, haematology parameters and meat characteristics of fat-tail lambs

Abstract The dietary effects of ensiled pomegranate by-products (EPB) with different levels of polyethylene glycol (PEG) on growth performance, nutrient digestibility, haematological parameters, carcase traits, and meat quality of fat-tail lambs were investigated in vivo. Thirty-two lambs were allocated to four experimental diets: containing: (1) diet without EPB as control, (2) diet containing EPB (EPB), (3) diet containing EPB with 5% PEG (EPB5%PEG) and (4) diet containing EPB with 10% PEG (EPB10%PEG). The nutrient digestibility, growth performance, internal organs, carcase traits, and chemical composition of Longissimus thoracis et lumborum (LTL) were unchanged between treatments (p > .05). However, a significant increase in fatty-acid profile of LTL (vaccenic acid, p = .04; C18:2 cis-9 cis12, p = .05; rumenic acid, p = .03; C18:2 trans-10 cis12, p = .02; alpha-linolenic acid, p = .01; punicic acid, p = .03 and total PUFA, p < .0001) was found in EPB-fed animals. The highest total antioxidant capacity (p = .001) and the lowest serum malondialdehyde concentration (p = .05) were observed in lambs fed EPB. The results indicated that dietary incorporation of EPB without PEG and its partial replacement with grains can improve animal health and meat fatty-acid profile without deleterious effects on growth performance. HIGHLIGHTS The fat-tail lambs were fed with ensiled pomegranate by-products (EPB). EPB improved the fatty-acid profile of Longissimus thoracis et lumborum and total antioxidant capacity of serum. EPB can be partially replaced with cereals without deleterious effect on performance.
Coating impact and radiation effects on optical frequency domain reflectometry fiber-based temperature sensors

Temperature response of radiation-tolerant OFDR-based sensors is here investigated, with particular attention on the impact of coating on OFS. By performing consecutive thermal treatments we developed a controlled system to evaluate the performances of our distributed temperature sensor and to estimate the radiation impact. We show an important evolution of the temperature coefficient measurements with thermal treatments for non-irradiated fiber and that the amplitude of this change decreases increasing radiation dose. As final results, we demonstrate that sensor performances are improved if we performed a pre-thermal treatment on the fiber-based system permitting to monitor temperature with an error of 0.05°C.

Chemical strategies for die/wafer submicron alignment and bonding.

This late-start LDRD explores chemical strategies that will enable sub-micron alignment accuracy of dies and wafers by exploiting the interfacial energies of chemical ligands. We have micropatterned commensurate features, such as 2-d arrays of micron-sized gold lines on the die to be bonded. Each gold line is functionalized with alkanethiol ligands before the die are brought into contact. The ligand interfacial energy is minimized when the lines on the die are brought into registration, due to favorable interactions between the complementary ligand tails. After registration is achieved, standard bonding techniques are used to create precision permanent bonds. We have computed the alignment forces and torque between two surfaces patterned with arrays of lines or square pads to illustrate how best to maximize the tendency to align. We also discuss complex, aperiodic patterns such as rectilinear pad assemblies, concentric circles, and spirals that point the way towards extremely precise alignment.
