| evaluating niger's experience in strengthening supervision, improving availability of child survival drugs through cost recovery, and initiating training for integrated management of childhood illness (imci). | background: who and unicef have recently developed the "integrated management of childhood illness" (imci) as an efficient strategy to assist developing countries reduce childhood mortality. early experience with imci implementation suggests that clinical training is essential but not sufficient for the success of the strategy. attention needs to be given to strengthening health systems, such as supervision and drug supply. results: this paper presents results of evaluating an innovative approac ... | 0 | 11504567 |
| seasonal variation in metabolic rate, flight activity and body size of anopheles gambiae in the sahel. | malaria in africa is vectored primarily by the anopheles gambiae complex. although the mechanisms of population persistence during the dry season are not yet known, targeting dry season mosquitoes could provide opportunities for vector control. in the sahel, it appears likely that m-form a. gambiae survive by aestivation (entering a dormant state). to assess the role of eco-physiological changes associated with dry season survival, we measured body size, flight activity and metabolic rate of wil ... | 0 | 22623189 |
| comparative studies on respiration : ii. the effect of anesthetics and other substances on the respiration of aspergillus niger. | 1. in concentrations which are high enough to produce any effect, formaldehyde, ether, and acetone cause an increase, followed by a decrease, in the rate of respiration. 2. 3.65 per cent ether, which causes an increase with certain cultures, produces only a decrease with others. 3. the reaction producing an increase in the respiration with 7.3 per cent ether is a reversible process, while the reaction producing the decrease is not reversible. 4. 0.5 per cent caffeine produces only a decrease in ... | 1918 | 19871735 |
| comparative studies on respiration : ix. the effects of antagonistic salts on the respiration of aspergillus niger. | 1. in the presence of 0.05 per cent dextrose the respiration of aspergillus niger is increased by nacl in concentrations of 0.25 to 0.5m, and by 0.5m cacl(2). 2. stronger concentrations, as 2m nacl and 1.25m cacl(2), decrease the respiration. the decrease in the higher concentrations is probably an osmotic effect of these salts. 3. a mixture of 19 cc. of nacl and 1 cc. of cacl(2) (both 0.5m) showed antagonism, in that the respiration was normal, although each salt alone caused an increase. 4. sp ... | 1919 | 19871785 |

| the effects of certain heavy metals on respiration. | 1. the effect of the heavy metals on the respiration of aspergillus niger is to cause the rate of carbon dioxide production to decrease from the first or to increase and subsequently diminish. 2. the speed of the toxic action varies as a constant power of the concentration. 3. the temperature coefficient of the toxic action is between 1.5 and 2. 4. an hypothesis is advanced to account for the action of the heavy metals, by means of which the experimental results may be accounted for. it is assum ... | 1926 | 19872277 |
| a latent period in the action of copper on respiration. | 1. when copper chloride is allowed to act on aspergillus niger there is at first a period during which there is no change in the rate of the production of carbon dioxide, following which the rate of respiration falls. the interval of no change is called the latent period. 2. when the copper is removed from the external solution before the end of the latent period this interval is prolonged. the rate of respiration then falls to a new level below the normal level. 3. experiments on nitella and on ... | 1926 | 19872281 |

| the effects of ultraviolet radiation on spores of the fungus aspergillus niger. | the survival ratio of aspergillus spores exposed to ultraviolet radiation has been measured as a function of total incident energy for wave lengths of 2537 a, 3022 a, 3129 a, and 3650 a. the effect of humidity on killing of aspergillus spores by ultraviolet radiation has been found to be negligible. a delay in germination as a result of irradiation has been found. the bunsen-roscoe reciprocity law has been found to hold within the limits of the radiation intensities studied. certain morphologica ... | 1939 | 19873127 |
| electron bombardment of biological materials : ii. the rate of death of fungus spores bombarded in vacuum with cathode ray beams from 4 kv.-15 kv. | a study has been undertaken of the rate of inactivation of spores of the ascomycete fungus aspergillus niger when bombarded in vacuum, with homogeneous beams of cathode rays of energies from 4 to 15 electron kv. and current densities of 1 x 10(-7) to 3 x 10(-6) amperes per square cm. these velocities and densities are in the range of those of showers of secondary electrons produced in biological materials irradiated with moderately soft x-rays, and so may be made to serve as quantitative indicat ... | 1940 | 19873162 |
