In situ X-ray diffraction study of enstatite up to 12 GPa and 1473 K and equations of state

Abstract Crystal structures and phase transitions of enstatite (MgSiO3) were studied by in situ X-ray diffraction experiments using synchrotron radiation and a multi-anvil high-pressure apparatus at pressures to 12 GPa and temperatures to 1473 K. Low clinoenstatite with space group P21/c transforms to high-pressure C2/c clinoenstatite at high pressures and high temperatures, accompanied by a volume reduction of about 2.5%. The ß angle of this high-pressure C2/c phase ranges from 101.4° to 101.7°, shows almost no variation with pressure and temperature, and is about 8° smaller than that of the high-temperature C2/c phase previously reported. This confirms the suggestion (Hugh-Jones et al. 1994) that these two clinoenstatite phases differ at high pressures and high temperatures. The pressure-volume-temperature data for P21/c and high pressure C2/c clinoenstatite were fit to room-temperature third-order Birch-Mumahan equations of state (EOS) using the parameters: volume of V0 = 415.4 (5) Å3, isothermal bulk modulus of K0= 108.5 (6.4)GPa, and its pressure derivative of Kʹ0 =4.5 (1.3) for the P21/c phase, and F0 = 405.1 (1.7)Å3,K0= 106.4 (17.4) GPa, and Kʹ0=5.4(2.7)forthe C2/c phase. These values are at ambient conditions. For the C2/c phase, we determined the high-temperature EOS, expressed as P = 3/2 Kt [(VT/V)7/3-(VT/V)5/3] {1-3/4 (4-KʹT[(VT/V)2/3-1]}, where Kt = K0 + (მKT/მT)P (T-300), KʹT=Kʹ0, Vt= V0[exp(ʃT300α(T)dT)], where thermal expansivity α(T) is a0 + a1 T. The parameters are V0 = 405.0 (2.6) Å3, K0 = 106.9 (25.9) GPa, Kʹ0 = 5.3 (3.9), a0 = 2.01 (44) × 10-5 K-1, a1 = 2.10 (1.1) × 10-8 K-2, and (მKT/მT)P = -0.021 (10) GPa/K. Although the K0 values are nearly the same with those of previous studies for both the P21/c and C2/c phases, the Kʹ0 values are slightly smaller.
Effect of Preemptive Clonidnine Versus Pethidine and Ketamine on Postoperative Shivering During Spinal Anesthesia

Introduction: Postoperative Shivering is an early postoperative complication. Incidence of postoperative shivering (POS) following surgeries varies between 20 to 60%. There is still no consensus on treatment modalities especially in opioid-dependent patients. Aim: To compare the effect of preemptive clonidine, ketamin and pethidine in controlling postoperative shivering in addicted patients who undergo spinal anesthesia. Methods: In a clinical trial, 81 patients who underwent spinal anesthesia for elective orthopaedic surgery for lower limb were enrolled and assigned to groups of 27 patients of the study based on accidental numbers, and 2 patients in Pethidine group and 2 patients in ketamine group were excluded from the study. Clonidine 2 mg was administered orally prior to surgery. Ketamin 2mg/kg and pethidine 0.5 mg/kg were administered in recovery to the patients. Postoperative shivering was measured in patients during stay in post anethesia care unit. Blood pressure and heart rate was recorded during 30 minutes after spinal anethesia in operating room. Results: No significant differences in blood pressure and heart rate were observed between patients. Incidence of postoperative shivering was 28% in clonidine, 36% in pethidine and 48% in ketamin group. Risk of shivering was significantly reduced in patients received clonidine in compare to ketamine (RR: 0.34, 95% CI: 0.138-0.856, p=0.022) which was significant and compare to pethidine (RR=0.79, 95% CI: 0.272-2.323, p=0.67) which was not significant. Conclusion: preemptive Clonidine has superior effect compare to postoperative ketamin and pethidine in controlling postoperative shivering.
Violent mergers of nearly equal-mass white dwarf as progenitors of subluminous Type Ia supernovae

Context. The origin of subluminous Type Ia supernovae (SNe Ia) has long eluded any explanation, because all Chandrasekhar-mass models have severe problems reproducing them. Recently, it has been proposed that violent mergers of two white dwarfs of 0.9 M� could lead to subluminous SNe Ia events that resemble 1991bg-like SNe Ia. Aims. Here we investigate whether this scenario still works for mergers of two white dwarfs with a mass ratio below one. We aim to determine the range of mass ratios for which a detonation still forms during the merger, as only those events will lead to an SN Ia. This range is an important ingredient for population synthesis and one decisive point for judging the viability of the scenario. In addition, we perform a resolution study of one of the models. Finally we discuss the connection between violent white dwarf mergers
Perceived Effectiveness of Assessments Used in Online Courses in Western North Carolina Community Colleges.

The purpose of this study was to determine the most appropriate methods of assessment for online courses. Internet instructors were surveyed and asked which methods of assessment they use in the online courses that they teach and how effective they perceive those methods to be in determining if the learning objectives have been met for the course(s) that they teach online. The findings of this study indicated that there is a difference between some academic disciplines in relation to the type of assessment methods being used in online courses. There is a difference in perceived effectiveness of assessment methods among the individual instructors surveyed. The most effective means of assessment as determined by the survey results is individual projects. The least effective method of assessment as determined by the survey results is self-assessment. The study's results confirmed that objective testing is not considered the most effective method of assessment; however, several instructors still use this method because of time constraints. The study's results confirmed that a variety of assessment methods need to be used within each Internet course to determine the effectiveness of the course. Surprisingly, there was no difference in the assessment methods being used by those instructors who received training and those who did not. This conclusion could be because the training received by most online instructors was in Blackboard and/or technology and not assessment methods. There is a difference in the number of types of assessment being used by online instructors. The survey data indicated that there was not a difference in assessment methods being used by instructors who have taught for more than three years as compared to instructors who have taught three or fewer years. The study indicated that there is a difference in some of the types of assessments being used by instructors who teach more than one Internet course per year. Not surprisingly, instructors who have a large number of students and/or course sections resort to objective testing methods only because they do not have time to grade alternative assessment formats.
Vertical-cavity surface-emitting lasers for medical diagnosis

This thesis deals with the design and fabrication of tunable Vertical-Cavity Surface-Emitting Lasers (VCSELs). The focus has been the application of tunable VCSELs in medical diagnostics, specifically OCT. VCSELs are candidates as light sources for swept-source OCT where their high sweep rate, wide sweep range and high degree of coherence enable deep probing of tissue at acquisition rates that will eliminate the effects of rapid involuntary eye movements. The main achievement of the dissertation work has been the development of an electro-statically tunable VCSEL at 1060 nm with wide tuning range and high tuning rate. The VCSEL is highly single-mode and inherently polarization stable due to the use of a High-index Contrast subwavelength Grating (HCG). HCG VCSELs are presented with 1.5% relative tuning range at a tuning rate of 850 kHz. The thesis reports on the analysis of narrow linewidth Fabry-Perot filters with dissimilar mirrors and the design of such Fabry-Perot cavities for VCSELs. Fabrication of InGaAs multiple quantum wells with GaAsP strain balancing layers is covered together with the growth and wet chemical etching of InAlP. The fabrication of the proposed Fabry-Perot filters and VCSELs is outlined and the results on their characterization reported.
Preconditioning for boundary control problems in incompressible fluid dynamics

PDE‐constrained optimization problems arise in many physical applications, prominently in incompressible fluid dynamics. In recent research, efficient solvers for optimization problems governed by the Stokes and Navier–Stokes equations have been developed, which are mostly designed for distributed control. Our work closes a gap by showing the effectiveness of an appropriately modified preconditioner to the case of Stokes boundary control. We also discuss the applicability of an analogous preconditioner for Navier–Stokes boundary control and provide some numerical results.
Utilization of Soft-rot Cavity Orientation for the Determination of Microfibril Angle. Part I

These studies utilize the decay cavities formed by the soft-rot fungus, Phialocephala dimorphospora, to determine the orientation of the cellulose fibrils in the cell wall. In this study, the microfibril angle was determined utilizing three methods: X-ray diffraction (T method), iodine staining, and orientation of the soft-rot cavities. The results demonstrate good agreement between the three techniques and verify that the decay cavities are formed in a direction parallel to the cellulose microfibrils and therefore can be used to determine the orientation of the cellulose microfibrils. One advantage of the soft-rot method over the X-ray method is the ability to measure angles of any size, including those of juvenile wood.
COMPUTATIONAL AND EXPERIMENTAL INVESTIGATIONS OF BOUNDARY LAYER TRIPPING

Supersonic flow over a tapered body of revolution has been investigated both experimentally and numerically. The experimental study consisted of a series of wind tunnel tests on an ogive-cylinder body. Static pressure distributions on the body surfaces at several longitudinal cross sections, as well as the boundary layer profiles at various angles of attack have been measured. Further, the flow around the model was visualized using Schlieren technique. Tests with a natural development of the boundary layer and with tripping were also carried out. All tests were conducted in the trisonic wind tunnel of Qadr Research Center. Our results show that artificial boundary layer tripping has minor effect on the static surface pressure distribution (depending on its diameter and installation location), while the changes in total pressure around the body were significant. Tripping the boundary layer increased its thickness, changed its profile particularly near the body surface. Two oblique shock waves were formed in the front and behind the trip wire. In this study, using multi-block grid, the thin layer Navier-Stokes (TLNS) equations were solved around the above models. Also patched method was used near the interfaces. Good agreements were achieved when the numerical results were compared with the corresponding experimental data.
Corporate Governance and Firm Performance: Evidence from Saudi Arabia

This study aimed to measure the impact of Corporate Governance on Firm performance of listed companies in Saudi stock exchange. The study methodology was a pooled data collected from the Saudi stock exchange (TADAUWL) for the period from 2012 to 2014. The study sample is 171 listed companies. The study independent variable is Corporate Governance principals. The dependent variable is Firm performance which was measured using ROA, ROE and Tobin's Q. The study also utilized five control variables in order to help measuring the relationship between Corporate Governance and Firm Performance. In conclusion, the study found that the governance level was 61.4% in Saudi stock exchange which is considered high compared to previous studies. The results of the study test indicate that there is no significant impact for corporate governance adoption on firm's operational and financial performance in the listed companies in Saudi stock exchange. By testing the Tobin's Q model the study also concluded that there’s no significant impact for ownership of the largest shareholder and independency of Board of Directors on firm's market performance. Significant impact was found for the ownership and the size of the Board of Directors on firm's performance.
Fibrosed Mucocele Associated with Abnormal Frenal Attachment - A Case Report

Mucoceles are defined as mucus-filled cavities that can appear in the oral cavity, appendix, gall bladder, paranasal sinuses or lacrimal sac. The most common location of mucocele in oral cavity is the lower lip. This report describes a lesion of the upper lip that was definitively diagnosed by histopathological examination as a fibrosed mucocele. This case illustrates an uncommon presentation of mucocele with respect to symptoms, location and duration. This report will help clinicians in establishing an appropriate differential diagnosis and thereby prepare them to expect the unexpected.
Pediatric Kidney Transplant in Uropaties

In 1954 Murray performed the first truly successful pediatric kidney transplant from one homozygous twin to another (Murray et al., 1958). In 1966 Kelly reported a kidney transplantation in a patient with dysfunctional bladder who had undergone ileal segment urinary diversion (Kelly et al., 1966). Until that time, patients with ESRD and untreatable dysfunctional urinary tract were excluded from renal transplant programs. At that time, it was believed that the renal allograft connected to a dysfunctional bladder would run the same risk as the native kidneys, that is, the result would be again renal insufficiency (Sheldon et al., 1994).
Behavioral Responses to Inheritance and Gift Taxation: Bunching Evidence from Germany

The desirability of inheritance and gift taxes depends on individuals' tax responsiveness. This paper demonstrates how strongly, and in what way, the German inheritance and gift tax influences taxpayer behavior. To that end, it combines administrative data with cross-bracket tax variation: a convex kink in the tax liability precedes a concave kink. Extending the bunching approach to such double-kinked tax schedules, I document that individuals tailor their taxable wealth transfers to the schedules. One type of response dominates for inheritances: testators engage in testament planning. The magnitude of the testament-planning response is comparable to that of inter vivos gifts. However, neither the overall responses of gifts nor those of inheritances heavily interfere with tax revenue collection: the associated short-run net-of-tax elasticities of taxable wealth transfers lie below 0.1.
OUTCOMES OF DIFFERENTIATED THYROID CARCINOMA (DTC) PATIENTS AT MAHARAJ NAKORN CHIANG MAI HOSPITAL (MNCM)

Objective To compare the outcome of DTC patients treated at MNCM with various types of therapy. End point measurements were cancer recurrence and cancer death. Materials and methods A retrospective review of all available medical records of DTC patients from January 1988 to December 1998 was performed. Some patients, who were diagnosed DTC long before 1988 and had continued to follow-up, were included in this study. There were 292 patients (225 female and 67 male) comprising 54.5% papillary cell carcinoma, 39.7% follicular cell carcinoma and 5.8% mixed papillary and follicular cell carcinoma.
Postural differences in cardiac dynamics during quiet and active sleep in low birthweight infants

To study the effects of body position (supine versus prone) on changes in cardiac inter‐beat interval during quiet and active sleep, 6‐h continuous electrocardiographic recordings and simultaneous minute‐by‐minute behavioural activity state assignments were made in 61 healthy, growing, low birthweight infants. The infants weighed 795‐1600 g at birth and ranged between 30–38 wk in postconceptual age. Infants were randomly assigned to the supine or prone position for the first 3 h of each study; the position was reversed for the second 3 h. Higher heart rates and lower time and frequency domain measures of inter‐beat interval variability were observed in the prone position as compared to the supine position, during both quiet and active sleep. In addition, an analysis of consecutive increases and decreases in the instantaneous heart rate revealed a lower incidence of sustained accelerations or decelerations in the prone position. Although consistent findings concerning inter‐beat interval variability and sleeping position were obtained from all analytic techniques, the differences derived from analysis of consecutive inter‐beat changes were the most robust. These differences in multiple measures of cardiac rate and rhythm between prone and supine positions suggest that autonomic control of the heart is altered by body position, the net effect on heart rate being increased sympathetic dominance.

The Influence of Programming Training on the Computer Literacy and Attitudes of Preservice Teachers

AbstractThis pretest/posttest study measured the change in knowledge of computers and attitudes toward computers among 36 preservice teachers enrolled in an introductory computer training course. This course was oriented towards developing basic computer programming skills. Significant gains were achieved in attitudes toward computers, both in the overall Computer Attitude Index and in five of the six component attitude dimensions of this Index. Moreover, attitude gains were correlated with achievement in the course. Most students entered the course with relatively high levels of computer literacy. Nevertheless, gains in this domain were significant in all measured dimensions except that of Knowledge of Computer Uses. Gains in the Computer Literacy Index were correlated with course achievement. No gender effects were detected, and only one age-related correlation was found.
A Survey of Culture Teaching in College English

This study introduces the condition of culture teaching in college English in China by using the quantitative research method. Through analyzing the quantitative data by means of various inferential statistical procedures, and investigating how the students’ recognition, favorite approach, ideas, and attitudes on culture teaching interact and students’ sex-, major-and place-related differences in culture teaching, the results show that culture learning plays a positive part in learning language. The results also indicate that the degree of the satisfaction on cultural learning of the students is varied by sex, major, grade and place. This phenomenon urges that all the language teachers should find suitable and reliable teaching resource in directing and implementing the language-and-culture teaching. Teacher should adjust and develop the existed content-based instruction into a more feasible way and also take on more responsibilities on the students in the process of learning. This calls for further study in the field of culture teaching.
Monetary Policy in a Small Open Economy Model: A DSGE-VAR Approach for Switzerland

We study the transmission of monetary shocks and monetary policy with a behavioral model, corrected for potential misspecification using the DSGE-VAR framework elaborated by DelNegro and Schorfheide (2004). In particular, we investigate if the central bank should react to movements in the nominal exchange rate. We contribute to the empirical literature as we use Swiss data, which is very rarely used in that context.

Anthropometric and General Health Measures in Elderly Exercisers and Yoga Practitioners: A Comparative Study

Obesity is a growing problem, resulting in significant morbidity and mortality from weight-related diseases and reduced quality of life. The association between elevated BMI and subsequent disability provides evidence that obesity in older populations is associated with a substantial increase in risk for poor health outcomes. A total 102 elderly male subject above 60 yrs of age selected for study. Thee groups were prepared with 34 subject in each group. Group 1 subjects who are practicing yoga more than 3yrs. Group 2 subject doing daily light exercise for last 3yrs. Group 3 control group who are not practicing yoga or exercise. Height, Weight, BMI, mid arm circumference, mid calf circumference, waist hip ratio and BMR recorded. Socio demographic and general health questionnaire recorded and data analyzed. Result of present study shows that the yoga group have lower thresholds of BMI and BMR. Anthropometric norms are with in normal limits for their respective age. Yoga group reported better health, lower somatic symptoms, anxiety and depressive state. Yoga rather than physical exercise is recommended for preventive and promotive health in elderly.
