Heavy water distillation carried out via vacuum distillation in packed columns is a necessary facility at every heavy water based nuclear power plant. This is an energy intensive process technology and has a significant impact on the overall economics of nuclear power production using heavy water based power reactors. Energy consumption patterns and energy saving opportunities in a typical water distillation plant are analysed in this work. The mathematical models and solution codes developed in-house are used to perform these calculations.
This report is the first description of the use of Serum Amyloid A in a free-ranging gull spp. Combined with haematological and biochemical parameters this biomarker might be a valuable tool in order to investigate the physiological status of wild avian species. An adult herring gull (Larus argentatus) found lethargic and moribund showed an open fracture of the right radius and ulna with necrosis of the surrounding tissue. Hematologic testing and plasma biochemical analysis revealed elevated creatinine kinase consistent with traumatic muscle damage in addition to hyperuricemia, hyperkalaemia, and hyperphosphatemia consistent with renal insufficiency. Marked increase in the acute phase protein Serum Amyloid A indicated a high degree of inflammation supported by leucocytosis, heterophilia, and hypoglycaemia pointing towards septicaemia. This case provides knowledge about Serum Amyloid A in gulls, and how bone fracture and secondary infection may affect gull blood haematology and biochemistry. Serum Amyloid A seem to be an important tool in the diagnosis of inflammation in avian species along with standard haematology testing and we encourage further studies on Serum Amyloid A in general as well as studies providing reference ranges in other domestic and wildlife avian species.
Anaerobic digestion of textile wastes under mesophilic conditions were conducted in batch mode with aim of investigating the bio-methane evolution with an initial solid mass of cow dung – 2 kg, cotton and water in 3:1 ratio and press mud is use in the ratio 3:1 with water were evaluated subsequently for 7 weeks (42 days).The highest production of biogas is noted as 3 m3 in fourth week and the higher production of biogas due to press mud is noted as 0.49 in the fifth week. Carbon dioxide is produced as bi product in this bio digestion process. Highest production rate of methane, biogas and carbon dioxide are in their fourth week. Through this experiment 65%-75% of bio gas is collected by the fourth week.
Objectives: It was aimed to evaluate the effects of nutritional factors, dependence in daily life activities, and polypharmacy on hospitalization time, clinical prognosis and mortality in hospitalized older COVID-19 patients.\nMethods: 503 hospitalized patients with PCR (+) COVID-19 disease were retrospectively evaluated and patients aged ≥ 60 patients were included. The first admission findings, comorbidities, number of drugs used (polypharmacy) were obtained. The Mini Nutritional Assessment (MNA), Barthel (BADL) and Lawton Instrumental Activities of Daily Living (IADL) were applied. \nResults: Of the 73 patients, 39 were female and the mean age was 69.65 ± 7.39 years. 14 (19.2%) patients were tranferred to intensive care unit, and 9 (12.3%) of them died there. 64 patients were discharged. When the patients who were transferred to intensive care/ex and discharged from the hospital were compared separately, the number of respiration at the first admission were significantly higher, and BADL, IADL scores and oxygen saturations were found to be significantly lower, even after ajustment for age (p<0.05). There was no relationship between hospitalization time and age, number of drugs, BADL and IADL scores, but significant negative correlation between hospitalization time and MNA score and daily protein intake (r: -0.310, r: -0.275, respectively; p<0.05). There was no relationship between polypharmacy and clinical progression of COVID-19 (p>0.05).\nConclusion: While the decrease in MNA scores and daily protein intake in older COVID-19 patients was associated with prolonged hospitalization, functional dependence was associated with the need for intensive care and mortality.
A multifunctional nanobiocomposite polymer was developed in this study through a cross-linking polymerization of cyclodextrin with phosphorylated multi-walled carbon nanotubes followed by sol-gel for the incorporation TiO2 and Ag nanoparticles. This developed multifunctional nanobiocomposite polymer was characterized using a range of spectroscopy and electron microscopy techniques. Fourier-transform infrared (FTIR) confirmed the presence of oxygen containing groups on the developed nanobiocomposite polymer and carbamate linkage (NH(CO)) distinctive peak at around 1645 cm-1 which is an evidence that the polymerization reaction was successful. The developed nanobiocomposite polymer has a rough surface. It was also successfully tested as a filter nanosponge to remove organic, inorganic, and microorganisms’ pollutants from wastewater samples. The multifunctional nanobiocomposite polymer was designed to be as cost-effective as possible that is, it can be regenerated and re-used.
Background. Due to the pandemic caused by the SARS-CoV-2 virus, the great health problem it represents, and the lack of a vaccine that approves all clinical phases, it is necessary to develop therapeutic strategies to control the spread of the virus. Objective. Evaluation of Ivermectin and Nitazoxanide for the treatment of early phases of patients with symptoms suggestive of COVID-19. Methods. 93 patients with symptoms suggestive of CODIV-19 who attended a terminal outpatient clinic at the Health Center of the Secretaría de Salud de Nuevo León and met the inclusion criteria were evaluated for 14 days after administering single doses of Ivermectin, Nitazoxanide or Paracetamol. Results. The statistical analysis of the results showed a significant difference between the means of the recovery days of the patients who received the Ivermectin + Paracetamol treatment and the patients who received only Paracetamol (95% CI 0.4648-3.640; p <0.0077). Conclusions. The administration of Ivermectin or Nitazoxanide did not show an improvement in the recovery time compared to the administration of Paracetamol in patients with symptoms suggestive of COVID-19.
In this paper we consider an approach of changing the temperature of liquids and gases in the pipeline by local heating and cooling. A model of heat transfer taking into account convection and an analytical approach for its analysis are introduce.
