Nonlinear Aeroelastic Response of Highly Flexible Flying Wing Due to Different Gust Loads
Nonlinear aeroelastic responses of a flying wing aircraft due to different gust profiles are investigated. Three different gust profiles are obtained considering light, moderate, and severe turbulence. A flying wing configuration is designed for the purpose of this investigation. The structural properties of the wings are obtained using VABS software, and then the flying wing is simulated with Nonlinear Aeroelastic Trim and Stability of HALE Aircraft (NATASHA) computer program. The results of time domain analysis are reported for the cases when engine is placed at the root of the wing and close to the area of maximum flutter speed. It has been found that the flying wing experiences limit cycle oscillation, when the engines are mounted at the root of the aircraft, for all three gust profiles. However, when the engines are placed at the area of maximum flutter speed, the oscillations die out. In addition, the real and imaginary part of eigenvalues and the unstable mode shape of the aircraft are reported
The effect of 10-week aerobic training with and without ginger supplementation on aerobic power, BFP, and insulin resistance in obese middle-aged women with type 2 diabetes
Background and aims: Diabetes is a metabolic disorder associated with diseases. The use of supplements, herbal extracts, and exercise training for the treatment of diseases and metabolic disorders has increased among people. Thus, the aim of this study was to investigate the effect of 10-week aerobic training with and without ginger supplementation on aerobic power, BFP, and insulin resistance in obese middle-aged women with type 2 diabetes. Methods: In this study, 46 obese diabetic women (BMI > 30, blood fasting sugar more than 150-250 mg/dL, 45-60 years old) were selected and randomly assigned into four groups, ginger (n=12), aerobic exercise training + ginger (n=12), aerobic exercise training (n=12) and control (n=10). Participants in supplementary groups received four 250 mg capsules ginger extract 1000 mg daily for 10 weeks. Aerobic training program included 10 weeks of training, 3 sessions per week and each session was 60 minutes at 55 maximum heart rate during the first week and gradually increased with the progress of the training program to 75 percent of maximum heart rate. Results: After 10 weeks, significant difference was observed in weight, BMI, body composition, VO2max, Insulin, fasting glucose and insulin resistance (P<0.05). In the within group changes was observed significant decrease in insulin levels and insulin resistance was in the aerobic exercise training + ginger group (P<0.05). Conclusion: According to obtained results, it appears that aerobic training plus ginger extract consumption have better effect on insulin levels and insulin resistance in obese middle-aged women with type 2 diabetes
Synovial cavernous hemangioma with juxta-articular hemangioma in a 29-year old woman: A case report
Introduction: Synovial hemangiomas are a rare benign vascular malformation that most commonly affects the knee joint, usually involving the anterior compartment. Histopathology examination is considered the gold standard for the diagnosis of synovial hemangioma. Surgical excision, either done per arthroscopy or per arthrotomy, is the treatment of choice. Presentation of case: This study presents a 29-year-old female admitted to our hospital in March 2020 who complained of continuous pain, swelling, and recurrent haemarthroses without a history of trauma for six months. The anteroposterior and lateral plain radiographs of the left knee showed no abnormality. An ultrasound of the left knee showed lobulated hypoechoic lesions in intra-articular and infra-suprapatellar pouches. Multiple vessels within the lesion with the low-velocity venous flow have appeared in color-Doppler imaging. Magnetic resonance imaging (MRI) of the left knee showed an irregular soft tissue mass in intra-articular fossa that infiltrating infra-suprapatellar pouches along to vastus medialis muscle (juxta-articular areas) measuring about 87 � 72 � 75 mm. Synovial effusion and bone erosions were notable. Fine-needle aspiration cytology (FNAC) offered hemarthrosis. The excisional biopsy obtained from the lesion and imprint cytology performed immediately after tissue removal. The cytologic diagnosis was compatible with a benign vascular neoplasm. The histologic exam confirmed synovial hemangioma. Discussion: Synovial hemangioma is a rare benign tumor of vascular origin arising from synovium-lined tissues, and often affects adolescents and young adults. Synovial hemangioma is often associated with an adjacent cutaneous or deep soft tissue hemangioma. It is a vascular malformation that contains variable amounts of adipose, fibrous, and muscle tissue, as well as thrombi in the vessels. At present, MRI has become the modality of choice for the evaluation of hemangiomas. The final diagnosis established with the histologic examination. The choice treatment is surgical excision. Conclusion: Although synovial hemangioma is a rare condition, be considered for non-specific clinical symptoms. However, an early diagnosis of synovial hemangioma is fundamental for adequate treatment. © 2020 The Author

Effects of epidemiology learning software on nursing and midwifery students
Background: Being informed of new methods of teaching and comparing their outcome help teachers use more effective and efficient methods in developing and implementing new training courses. The aim of this study was to examine the efficacy of epidemiology learning software on learning epidemiology courses. Methods: This quasi-experimental study included 101 nursing and midwifery students taking epidemiology course in two separate classes. One of the classes was selected as intervention group (taught via software) and another one as the control group. At the end of the semester, scores of the courses were analyzed using covariance analysis. Results: After adjusting the effect of grade point average, covariance analysis indicated a significant difference in epidemiology scores between the two groups (p<0.001). The students taught through the software obtained significantly higher scores compared to the students in traditional group. Conclusion: By means of this training software, teachers can use several strategies for presenting lessons and increasing training efficacy, leading to active learning in students
Right side splenorenal fusion with marked extramedullary hematopoiesis, a case report
Developmental abnormalities of the spleen are common, much less common is splenic fusion abnormality. It may present as a renal mass sometimes with symptoms of hypersplenism (anemia) or as a renal mass only, mimicking primary or secondary renal neoplasms on imaging studies. Its documented that occurred on the right side which is significant that provides evidence for the possible migration of spleen cells in embryogenesis as an explanation for some other splenic fusion anomalies. We report a case of splenorenal fusion in a 5-year old girl with only right functional kidney who initially presented with a large renal mass which mimicked a primary renal neoplasm with no history of splenic trauma or splenectomy in past medical history. Also, the child didn't present with symptoms of hypersplenism. The child underwent right nephrectomy for a renal mass that was subsequently confirmed as right splenorenal fusion pathologically. © 201
