Factors affecting improvement of fluorescence intensity of quartet and doublet state of NO diatomic molecule excited by glow discharge

We report on the observation of new fluorescence emission spectral transitions obtained from NO diatomic molecule in the region from ultraviolet （UV） to near infrared （NIR） in a low power glow discharge system. This glow discharge electronic excitation populates different quartet and doublet states of NO in its proximity such as the A2Z （/9 = 2）, b4∑- （υ= 3）, B2М （1） = 4）, and X2Л （u= 33-32） states. Due to inter-system crossing, emission lines originating from these levels to lower lying states are recorded and spectral line assignments are performed. The observed systems include b4∑- a4∏, B21∏-a4∏, a4∏-X2I∏, A2∑X2∏, X2∏-X2∏ （33-15）, X2∏-X2∏ （33-17）, X2∏-X2∏ （33-20）, and X2∏-X2∏ （33- 18）. This new information will conduce to the better understanding of the interesting features of NO molecule. Such parameters that affect the recording of low density of NO molecules are also discussed In addition to the factors such as the time evolution, argon gas concentration relative to NO mixture, the percentage of NO molecular gas concentration, discharge electric current signals and discharge applied voltage are studied. Those factors would enhance the fluorescence signal intensity of NO molecules. The recent results might be significant as reference data for optimizing the glow discharge spectrometer and diagnostics of NO gas.

Background: Dengue virus (DENV) infection is caused by an arboviral strain and is transmitted by the mosquito Aedes Egyties which is found in Sudan especially Red Sea and Kassala states in the east. In the year 2020 there was a significant outbreak in the both states. The disease is known to cause renal and electrolyte disturbances and a thorough understanding of that which will potentially help in the prediction, diagnosis and treatment of the disease. Methods: This study is a prospective observational cross sectional study conducted in the Eastern Sudan College of Medical Science and Technology and Port Sudan Teaching Hospital. 200 confirmed Dengue virus infection patients along with 200 healthy appearing adults (as a control) were enrolled for the study. Statistical analysis was carried out after the collection of patients’ demographic, clinical, and investigational data including electrolyte values. Results: The highest incidence of DENV infection was observed in individuals of the middle age group (29%). Although fallen within reference ranges found in the literature, mean serum electrolyte values differed significantly between patients and controls and between different categories of the disease. For our patients, hyponatraemia was seen in 43.5%, hypokalaemia in 37%, hypocalcaemia in 30%, hypophosphataemia in 12% and low magnesium concentrations in 13%. Mean serum sodium concentration differed in the control (138.2 mmol/l) from in the test (132.5 mmol/l) (P. value 0.02). Similarly, mean serum potassium in the control (3.97 mmol/l) differed significantly (P. value 0.01) from test (3.30 mmol/l). Mean calcium and phosphorus (8.80 and 3.50 mg/dl) in the control were also differed from test (8.51 and 3.30), (P. values 0.02 and 0.004, respectively). In contrast, serum magnesium (mg/dl) in the control group (1.96) showed no significant difference from that of test group (1.90) (P. value 0.08). The biochemical parameters studied were neither affected by age nor by gen
