Factors Affecting Biological Control of Pythium Ultimum on Alfalfa using Seed Treatment with Gliocladium Virens, Trichoderma Harzianum and T. Hamatum

Gliocladium virens Miller et at. applied as a seed treatment controlled alfalfa (Medicago sativa L. ‘Travois’) damping-off in natural soils artificially infested with high levels of Pythium ultimum Trow, but Trichoderma hamatum (Bon.) Bain and Trichoderma harzianum Ragai were not effective at relatively high soil pH levels. Biocontrol with G. virens was nearly as effective as metalaxyl seed treatment, and better than Captain in most environments. Biocontrol was optimum at sail temperatures between 15 and 30 C, soil moistures of 15% to 30%, soil pH of 6 to 8 and when seeds had been treated with conidial concentrations of 109 spores/ml or greater. In a parallel study of steamed soils infested with P. ultimum, biocontrol was most effective between 25 and 35 C. at relatively low soil moistures, and as pH levels of 6 to 8. Amendment of the biocontrol spore suspension with bleached chitin did not affect the ability of the antagonists to protect alfalfa against P. ultimum, while unbleached chitin consistently destroyed effective biocontrol. G. virens seed treatment also effectively controlled damping-off in field tests. In vitro, 30 C and lower pH levels were optimum conditions for growth and sporulation of all three biocontrols

NASA Lewis F100 engine testing

Two builds of an F100 engine model derivative (EMD) engine were evaluated for improvements in engine components and digital electronic engine control (DEEC) logic. Two DEEC flight logics were verified throughout the flight envelope in support of flight clearance for the F100 engine model derivative program (EMPD). A nozzle instability and a faster augmentor transient capability was investigated in support of the F-15 DEEC flight program. Off schedule coupled system mode fan flutter, DEEC nose-boom pressure correlation, DEEC station six pressure comparison, and a new fan inlet variable vane (CIVV) schedule are identified

Science as a Subject of Learning in Islamic University

This paper aims to searching theological impact when applied a science as a subject of learning at Agrotechnology Department in the Faculty of Sciences and Technology of State Islamic University of Bandung. The atmospheric experiment was implemented as a subject of learning. By observing the atmospheric data recorded, the plant growth measured significantly affected by the implementation of treatments, the best water supply and fertilizer application. Furthermore, it found that local climate has changed, and Schmidt and Ferguson classification of regional rain types is no more valid, thus, should be renewed. The experiment impacted to a science learning program in Islamic University. Climatic change is a natural law affected by human destructed to the nature. It has been affecting farmers to maintain for their plantation activities. When organisms were effort to surviving in warmer and unpredictable condition, that is shows to human kind has to obligatory to the Almighty God

Thoracoscopic excision of asymptomatic posterior mediastinal ganglioneuroma. A case series study

Background Posterior mediastinal ganglioneuroma is the most frequent type of neurogenic tumors, and usually it is asymptomatic. The surgical approach to excise it may differ from center to center based on the surgeon's experience as well as the size of tumor. We aim to present our center's experience and short-term outcomes in surgical excision of posterior mediastinal ganglioneuroma. Methods This retrospective case series study, from June 2019 till December 2022, included 9 asymptomatic patients with mean age of 31± 5 years who expressed lesion in the posterior mediastinum. The mean size of the tumor was   5.3±3.6 cm in maximal dimensions.  Results There were 7 males and 2 females with mean age was 31± 5 years,  the excision by video-assisted thoracoscopy (VATS)  was  employed in 8 patients and conventional thoracotomy was carried out in 1 case.  The mean operative time was 57±14 minutes with mean operative blood loss 50±10 ml. The mean postoperative chest tube drainage was 120±80 ml and no complications related to the procedures were observed. The average time of hospital stay after VATS treatment was 2 days, while after thoracotomy it was 5 days and patient suffered from ptosis that eventually recovered after 1 month with supportive treatment. Histopathological examination confirmed benign nature of ganglioneuroma in all cases. Conclusions Thoracoscopic excision of asymptomatic posterior mediastinal neurogenic tumor is safe, feasible and reduces postoperative pain, however, open technique might be considered for large-sized tumor to minimize the possible complications

Adherence of Healthcare Professionals to Evidence-based Clinical Practice Guidelines in the Management of Hemodialysis Patients, Khartoum State, Sudan

Introduction: Hemodialysis (HD) is a complex procedure with many specifications and requires adherence to a set of particular clinical practice guidelines. These guidelines had already been established by globally acclaimed renal authorities and their implementation was shown to correlate with patients’ morbidity and mortality. This study was conducted to evaluate the adherence of healthcare professionals to the evidence-based clinical practice patterns in Khartoum State HD units.Methods: A cross-sectional study was conducted in Khartoum State HD units during the period from September 2010 to January of 2011. Data was collected from the healthcare professionals using a specially designed checklist. The checklist included the evidence-based clinical practice guidelines for the HD vascular access, HD adequacy, anemia of chronic kidney disease (CKD), nutrition, cardiovascular risk assessment, and hepatitis B and C virus infection control. Implementation of these guidelines was evaluated, and further graded using a Likert-type scale.Results: Four randomly selected HD units were included in the study. The rate of implementation of the HD vascular access guidelines was 54.8%, adequacy guidelines 57%, anemia of CKD 68.8%, nutrition 58.4%, cardiovascular risk assessment 57%, and hepatitis B and C infection control guidelines was 79.2%. Overall, the four HD units assessed showed moderate deviations from the practice guidelines of anemia of CKD and hepatitis B and C infection control. Extreme deviations from the clinical practice guidelines were seen in HD vascular access practices, adequacy assessments, nutrition and cardiovascular risk assessment.Conclusion: Hemodialysis services in Khartoum State are in need of great improvements regarding adherence to protocols and the standards of care.Key words: Clinical practice guidelines; Hemodialysis; Suda
