Under these conditions, grain growth is characterized by the formation of large elongated rectangular grains in a matrix of normal grains. The multi-phase-field model is extended by mechanisms which are responsible for the abnormal anisotropic growth: anisotropic interface energy, anisotropic interface mobility and a recrystallization driving force. Two types of the mobility anisotropy are considered: anisotropy due to the misorientation between grains and anisotropy due to the dependency on inclination angles. The experimental data from heat treatments of the ceramic fiber Nextel 610 at 1200-1300 °C with different dwell times are examined by the proposed model. The comparison of the experiment and the simulation results at various times shows that the extended multi-phase-field model is able to simulate the microstructure realistically. In most model cases, abnormal grains have a rectangular shape, similar to the experiment. The best fit of the experimental grain size distribution and the grain shape is achieved by the simulation with the misotientation dependency of the interface mobility. Furthermore, it was shown that a strong decrease on the grain growth rate with time, observed in the experiment, can be reproduced by the simulations taking into account the segregation of impurities on grain boundaries that results in the decreasing grain boundary mobility.

Some cases continue vomiting despite of adequate pyloromyotomy. Several pre-and postoperative factors may have a role. The aim of this study is to detect infants at risk of prolonged PPMV. Methods Fifty-three infants with infantile hypertrophic pyloric stenosis were operated at single tertiary center. Laparoscopic pyloromyotomy was performed in all cases. According to toleration of oral intake, patients were categorized in two groups, A and B. Group A included cases who didn't vomit or vomited and stopped vomiting during the first 8 h postoperative, while group B included cases who continued vomiting for more than 8 h postoperative and got improved by time. Results Mean age was 30.24 and 38.23 days in group A and B, respectively. Mean body weight was 2.7 and 2.4 kg. Mean duration of symptoms was 12.3 and 18.4 days. Mean pyloric canal length was 18.6 and 20.2 mm. Mean muscle thickness was 4.5 and 6.9 mm. Conclusion There is prolonged period of PPV with increase of pyloric canal length, pyloric thickness, and duration of preoperative vomiting. PPV decreases with minmum body weight loss of infant at the time of operation.

There are few reports about pancreatic injury during LS. The purpose of this study is to spot on factors increasing the risk of pancreatic injury during LS in children. Patients and Methods: A total of 140 children had LS for benign causes. Children were categorized into A and B groups. LigaSure™ was used to control pedicle in Group A, while endoscopic staplers were used in Group B. Preoperative levels of amylase, lipase, and lactate dehydrogenase (LDH) were obtained. The mean of pancreatic enzymes and LDH values was calculated on the 3 postoperative successive days. Results: A total of 71 boys and 69 girls had LS. The mean splenic size was 13.50 cm in Group A and 12.51 cm in Group B. The mean operative time in Group A was 41.91 min and in Group B was 56.36 min. The mean level of amylase was 42.99 IU/ml in Group A and 75.70 IU/ml in Group B (P = 0.001). The mean level of lipase was 37 IU/ml in Group A and 76.66 IU/ml in Group B (P = 0.001). Conclusion: Pancreatic injury during LS is a rare complication usually presented on biochemical level. We believe that it is a hemostatic-dependent complication rather than splenic size or nature of disease.

Pectinase improved the yield, stable color, color-assayed as release of anthocyanins or carotinoids and clarity of the juice. A significant increase in the effectiveness of pectinase was observed as the concentration was increased from 0.05 to 0.50% v/w. However, at concentration > 0.25% v/w they tended to impart a bitter flavor in the juice. Among three concentrations of pectinase and cellulase, pectinase at 0.50% v/w produced higher yield, a sediment-free clear juice and high-quality juice. The results indicated that depectinated clarified prickly pear juice behaves as a Newtonian fluid. It was found that the activation energy (Ea) for viscous flow was in the range of 5.02 x 10(3)-20.06 x 10(3) kJ/mol depending on the concentrations of pectinase and cellulase enzyme treatment of prickly pear juice, in contrast to 22.15 x 10(3) kJ/mol in untreated juice. Volatile compound concentrations of twelve compounds were not affected by pectinase and cellulase treatment. Overall the quality of prickly pear juice was better in pectinase-treated juice compared with untreated and cellulase-treated juice.

Objectives: This prospective study was designed to assess the outcome of microvascular decompression (MVD) in patients with a more than 3-year history of intractable idiopathic trigeminal neuralgia (TN) and poor drugs response. Methods: Twenty one patients (8 females/13 males) with intractable idiopathic TN (group-1) were enrolled to MVD and followed up for two years postoperatively. Group-2 (n=15, 6 females/9 males), continued on drug under their will. The outcome responses, pain relief and morbidity, were evaluated using: Ten-cm visual analog scale (VAS), and the Barrow Neurological Institute (BNI) scoring. Results: All patients, who disclosed the inclusion criteria, clinically and MRI brain, got benefits as of MVD surgery. The immediate efficiency in group-1 was 95.2% (n=20) and 90.5% (n=19) painfreedom during follow-up. Gaze at the morbidity rate in both groups, group-1 had no significant signs of recurrence or surgical complications (P>0.5), although group-2 showed 53.3% (n=8) poor response to medical therapy over the same period of time with experience of drug intolerance (P<0.01). Conclusion: We concluded that MVD should be done early to avoid drug side effects and psychological drawbacks of long term pharmacotherapy and disease comorbidity.

A small incentive has been added on answering to very simple questions about information provided by the project as condition re-inforcer. At this stage, MSM's perception of barriers hindering use of condoms too is lessened through dissonance reduction i.e. reduction in perception of a discrepancy between attitudes and behavior. They are motvated to use condoms even if there is some personal disliking and/or lack of sexual pleasure is involved. Thirdly MSM are motivated to practice the continuous use of condoms through fulfillment of their deficiency and social needs. Networks have been established with other NGOs providing financial supports and elligible clients are forwarded to them. In the end, the production provides a condition reinforcer (satisfaction); thus the client, on perceiving reward of the performance, does not only act as guided but also advocates fellow MSM and their own clients to use condoms. Lessons learned: The success of the project is evident by increasing number of registered MSM; enhanced utilization of condoms and application of negotiation skills by MSM with their clients. Such innovative interventions may be expanded to other high risk groups and also other areas. (F.A. Boughdadi). Introduction: High frequency mechanical strain has been shown to stimulate bone strength in animals. However, the effects of vibration exercise on the human skeleton have rarely been studied. Particularly in post menopausal women, data on the efficacy of vibration loading are lacking. The aim of this study was to assess the effect of two different programs (whole body vibration and resistance exercise) for osteoporosis hindered. Materials and methods: Twenty four volunteers aged from 46-56 years (M= 52.21, SD = 4.73) were randomly assigned to a whole body vibration (power plate) group (n = 8) and resistance exercise (RES) group (n = 8) four times weekly for 16 weeks and control group, the wbv group performed static and dynamic knee extensor exercises on a vibration, (35-40)hz, the resistance exercise (RES) group performed knee extensors by dynamic leg press and leg extension exercises increasing from low (20 RM) to high (8 RM) resistance. The control group did not participate in any training; hip bone density was measured using DXA before and after intervention, leg strength by dynamometer, parathyroid and estradiol 17B by Eliza. Data were analyzed by means of ANOVA. Results: Vibration training improved leg strength p>0.05 and also significantly increased BMD of the hip. Non significant changes in BMD were observed in resistance training, no change in control group. Parathyroid and estradiol 17B increased significantly after vibration training p >0.05, non significant change was observed in resistance group and no change in control group. Conclusion These findings suggest that power plate training may be effective in osteoporosis and may modify risk factors in post menopausal women.
