The Influence of Physiological Status on Age Prediction of Anopheles Arabiensis using Near Infra-red Spectroscopy
No full textDetermining the age of malaria vectors is essential for evaluating the impact of interventions that reduce the survival of wild mosquito populations and for estimating changes in vectorial capacity. Near infra-red spectroscopy (NIRS) is a simple and non-destructive method that has been used to determine the age and species of Anopheles gambiae s.l. by analyzing differences in absorption spectra. The spectra are affected by biochemical changes that occur during the life of a mosquito and could be influenced by senescence and also the life history of the mosquito, i.e., mating, blood feeding and egg-laying events. To better understand these changes, we evaluated the influence of mosquito physiological status on NIR energy absorption spectra. Mosquitoes were kept in individual cups to permit record keeping of each individual insect’s life history. Mosquitoes of the same chronological age, but at different physiological stages, were scanned and compared using crossvalidations. We observed a slight trend within some physiological stages that suggest older insects tend to be predicted as being physiologically more mature. It was advantageous to include mosquitoes of different chronological ages and physiological stages in calibrations, as it increases the robustness of the model resulting in better age predictions. Progression through different physiological statuses of An. arabiensis influences the chronological age prediction by the NIRS. Entomologists that wish to use NIR technology to predict the age of field-caught An. gambiae s.l from their study area should use a calibration developed from their field strain using mosquitoes of diverse chronological ages and physiological stages to increase the robustness and accuracy of the predictions.\ud

Festuca ovina L., s.l. en Festuca rubra L., s.l. in Nederland
No full textThe author gives a survey of the taxa belonging to Festuca ovina L., s.l. and F. rubra L., s.l. as they occur in the Netherlands. Four species are distinguished, viz. F. ovina L., F. trachyphylla (Hack.) Kraj., F. heterophylla Lamk., and F. rubra L. F. ovina L. is represented by 3 subspecies, subsp. tenuifolia (Sibth.) Čelak., subsp. ovina, and subsp. cinerea (Vill.) Duyfjes, nov. comb.; F. rubra L. can be subdivided into 2 subspecies, subsp. rubra and subsp. juncifolia (St. Am.) R. Lit.
Of these taxa F. heterophylla is most probably introduced with grass-seeds; the others are native

Life of Saint Gregory the Great Written in Four Books by John the Deacon: A Translation and Commentary of Book III
No full textThose interested in St. Gregory and his times find constant reference to the life of that pope written by John the Deacon. Because no translation of that work has hitherto appeared in English, a group of students, at the suggestion of Dr. L.V. Jacks, director of the classical department of The Creighton University, decided to undertake a translation and commentary on the Vita as their piece of research. |Since Books I and II of the Vita Sancti Gregorii Magni were already in process of translation when this work was begun, the original plan was to present a translation and commentary on Books III and IV. However, as the manuscript took shape, it ran into a forbidding length--some three hundred pages of translation alone; hence the first plan was abandoned and the scope of the work was limited to the third book alone. The text used was that of J.P. Migne, Volume LXXV of Patrologlae cursus completus Patrum Latinorum, which in the course of this study will be referred to as the Patrologia Latina. |Through the commentary the author has endeavored to supplement and clarify the text and to present various views on controversial questions. No textual, grammatical, or stylistic problems are handled, herein since these points have already been treated by competent scholars in this field. |This study has the secondary purpose of examining the historiography of John the Deacon in the Vita III. As background material a chapter containing the few known facts about this Roman deacon of the ninth century and his works has been included; also a chapter dealing with the early life and writings of St. Gregory because this material is not included in Book III.ProQuest Traditional Publishing Optio
An Estimation of the Entomological Inoculation Rate for Ifakara: A Semi-Urban Area in a Region of Intense Malaria Transmission in Tanzania.
No full textAn entomological study on vectors of malaria and their relative contribution to Plasmodium falciparum transmission in the semi-urban area of Ifakara, south-eastern Tanzania, was conducted. A total of 32 houses were randomly sampled from the area and light trap catches (LTC) performed in one room in each house every 2 weeks for 1 year. A total of 147 448 mosquitoes were caught from 789 LTC; 26 134 Anopheles gambiae s.l., 615 A. funestus, 718 other anophelines and 119 981 culicines. More than 60% of the total A. gambiae s.l. were found in five (0.6%) LTCs, with a maximum of 5889 caught in a single trap. Of 505 A. gambiae s.l. speciated by polymerase chain reaction, 91.5% were found to be A. arabiensis. Plasmodium falciparum sporozoite enzyme-linked immunosorbent assay tests were performed on 10 108 anopheles mosquitoes and 39 (0.38%) were positive. Entomological inoculation rate (EIR) estimates were generated using a standard method and an alternative method that allows the calculation of confidence intervals based on a negative binomial distribution of sporozoite positive mosquitoes. Overall EIR estimates were similar; 31 vs. 29 [95% confidence interval (CI): 19, 44] infectious bites per annum, respectively. The EIR ranged from 4 (95% CI: 1, 17) in the cool season to 108 (95% CI: 69, 170) in the wet season and from 54 (95% CI: 30, 97) in the east of the town to 15 (95% CI: 8, 30) in the town centre. These estimates show large variations over short distances in time and space. They are all markedly lower than those reported from nearby rural areas and for other parts of Tanzania
