Ecological Analysis of Some Azerbaijan Phanerophytes in ex situ Conditions

Analyzes of the relationship of 115 species of phanerophytes used in cultural conditions (Azerbaijan) against some abiotic factors (light, temperature, water, wind, etc.) have been presented in the paper. 2 species of these taxa are hygrophytes, 56 species are mesophytes, 23 species are xerophytes, 9 species are mesoskerophytes and 25 species are xeromesophytes have been determined depending from the relationship with water according to the results of analyzes. 100 light-loving species, 15 shade-loving species, 97 wind-resistant species and 18 wind-resistant species were found as a result of the study.

The Pressor Response to the Drinking of Cold Water and Cold Carbonated Water in Healthy Younger and Older Adults

Purpose: Water drinking has been proposed for the treatment of orthostatic hypotension because it can increase blood pressure in patients. This study aimed to investigate whether drinking water with a cold or carbonation stimulus would cause a more effective pressor response, and whether it would be greater in older than in younger adults.Methods: We assessed blood pressure and heart rate from non-invasive arterial pressure (a volume-clamp method) and type II electrocardiography in 13 healthy young adults (6 females, 7 males; mean age, 19.9 ± 1.1 years) and nine healthy older adults (all females; mean age, 71.4 ± 4.2 years) who drank 200 mL of cold, cold carbonated, and room temperature water.Results: The pressor response to the drinking of cold and cold carbonated water was greater than that to room temperature water in both younger and older participants (p < 0.05; changes in systolic blood pressure of room temperature water, cold water and cold carbonated water in young: 15.31 ± 9.66, 22.56 ± 11.51 and 32.6 ± 17.98 mmHg, respectively; changes in systolic blood pressure of room temperature water, cold water and cold carbonated water in elderly: 21.84 ± 14.31, 41.53 ± 19.82 and 48.16 ± 16.77 mmHg, respectively). In addition, the pressor response to cold and cold carbonated water was persistent during the recovery period by about 5–10 mmHg (p < 0.05). Furthermore, the pressor response during the drinking and recovery periods was greater in the older than in the younger participants (p < 0.05).Conclusion: Our data suggest that even smaller amounts of water are able to elicit a sustained pressor response, in particular if the water is cold and carbonated. We speculate that the pressor effect may render cold and carbonated water an appropriate first aid method against certain forms of acute hypotension.

Phytodiversity in Relation to Some Environmental Factors Of Some Wetland Habitats

The present research work was carried out on phytodiversity in relation to some environmental factors of three ponds namely, Pond-1, Pond-2 and Pond-3 of Zanjira upazila at Shariatpur district, Bangladesh where a total of 13 parameters were measured for one year. Monthly average different parameters of three ponds varied : air temperature from 23.5-36.50˚ C, water temperature 21-30.50 ˚ C,pH 7.10-8.50, TDS 55-227 mg/l, EC 103-463 μS/cm, DO 2.90-19.94 mg/l, alkalinity 0.73-5.40 meq/l, SRP 7.11-229.84 μg/l, SRS0.84-13.34 mg/l, NO3-N0.02-0.96 mg/l, chla1. 18-31.97 μg/l, phaeopigment 0.26-5.46 μg/l and phytoplankton density 6.50-119.50×106 ind/l. The total number of 122 species of phytoplankton were recorded in the studied ponds. Phytoplankton density showed positive correlation with air temperature, water temperature, pH, TDS, EC, alkalinity and SRP for Pond-1. Phytoplankton density showed positive correlation with pH, TDS, EC, DO and alkalinity for Pond-2. On the other hand phytoplankton density of Pond-3 showed positive correlation with air temperature, water temperature, TDS, EC, alkalinity, SRP, SRS, NO3-N and chlorophyll-a. During the period of present investigation some aquatic plants were found to grow in those shallow margins of the studied three ponds. Results indicated that Pond-1 is in a position undergoing eutrophic status, Pond-2 and Pond-3 are in the oligotrophic status. If the anthropogenic disturbances are continued in these ponds, it is likely that in near future these ponds would turn to eutrophic. Bangladesh J. Bot. 50(4): 1087-1094, 2021 (December)

Cooling Temperature and Heat Transfer Coefficients in Cylindrical Heat Exchangers

The parameters behavior that characterize the process was carried out through an experimental investigation to obtain the cooling temperature, heat transfer coefficients and the heat flow in mineral coolers. The values of water temperature, water flow and mineral temperature were recorded at the inlet and outlet of the cylindrical cooler. Experiments were carried out with five values of the mass flow, keeping the cylinder revolutions constant. The calculation procedure for the system was obtained, in the mineral coolers the heat transfer by conduction, convection and evaporation predominates as a function of the cooling zone. A reduction in temperature is shown with increasing length, the lowest temperature values were obtained for a mass flow of 8 kg/s. The mineral outlet temperature should not exceed 200 oC, therefore it is recommended to work with the mass flow less than 10 kg/s that guarantees the cooling process.

Causticum hahnemanni, Conium maculatum and Lycopodium clavatum highly diluted medications decreases parasitemia in mice infected by Trypanosoma cruzi

Introduction: Benznidazole is the only medicine available in Brazil for Chagas’ disease treatment, however it presents low efficacy in the chronic phase and several adverse effects [1-3]. Aim: Evaluate the effect of Causticum hahnemanni, Conium maculatum and Lycopodium clavatum [4-6] administered to mice infected with T. cruzi. Method: In blind randomized controlled trial 42 male Swiss mice, 8 weeks of age, have been grouped: GCaus –treated with C. hahnemanni 13cH (n=10), GCon –treated with C. maculatum 13 cH (n=11), GLy –treated with L. clavatum13cH (n=10) and CG – control group (n=11) treated with 7% hydro alcoholic solution 13cH. The animals were infected intraperitoneally with 1.400 blood trypomastigotes of T. cruzi - Y strain. Medications were been prepared according to Brazilian Homeopathic Pharmacopoeia [7]. Medication was diluted in water (1mL/100mL) offered ad libitum, from amber recipient during 16 hours administered 48 hours before infection and 48, 96 and 144 hours after inoculation. Parasitological parameters assessed: total parasitemia (TP), maximum peak of parasites (MPP), pre-patent period (PPP) and area under curve (AUC). Parasitemia was evaluated daily counting from the first day of infection. Clinical parameters assessed: weight, temperature, water and food intake and excreta were measured counting from the 5º day before infection until animals’ death or checking negative parasitemia for 3 consecutive days. Mortality was registered for 75 days after infection. Ethics Committee for Experiments in Animals gave approval UEM 054/11. Statistical comparison of data was performed with Kruskal-Wallis test, with 5% significance. Results and Discussion: The diluted medications have been significantly reduced the parasitological parameters: MPP (p
