Application of Remote Sensing to Planimetric, Thematic, and Topographic Mapping

Results of studies indicate some of the potential applications of space photography to mapping. The imagery used was not optimum for mapping purposes, and there is considerable room for improvement. The ERTS A and B satellites are expected to provide imagery that will be useful for small scale mapping, both planimetric and thematic. The repetitive coverage capability will certainly be useful for monitoring changing phenomena. However, to solve the world mapping problems, other imaging systems will have to be flown. Film-return satellites and geosynchronous satellites may have to be used together with aircraft to provide imagery for rapid and efficient mapping operations. Until such systems are in use on a worldwide basis, there is little likelihood that the planimetric and topographic map needs, particularly of the developing countries, will be met

Rapid Nanoparticle Synthesis by Magnetic and Microwave Heating

Citation: Chikan, V., & McLaurin, E. J. (2016). Rapid Nanoparticle Synthesis by Magnetic and Microwave Heating. Nanomaterials, 6(5), 9. doi:10.3390/nano6050085Traditional hot-injection (HI) syntheses of colloidal nanoparticles (NPs) allows good separation of the nucleation and growth stages of the reaction, a key limitation in obtaining monodisperse NPs, but with limited scalability. Here, two methods are presented for obtaining NPs via rapid heating: magnetic and microwave-assisted. Both of these techniques provide improved engineering control over the separation of nucleation and growth stages of nanomaterial synthesis when the reaction is initiated from room temperature. The advantages of these techniques with preliminary data are presented in this prospective article. It is shown here that microwave assisted heating could possibly provide some selectivity in activating the nanomaterial precursor materials, while magnetic heating can produce very tiny particles in a very short time (even on the millisecond timescale), which is important for scalability. The fast magnetic heating also allows for synthesizing larger particles with improved size distribution, therefore impacting, not only the quantity, but the quality of the nanomaterials

Rapid Induction and Microwave Heat-Up Syntheses of CdSe Quantum Dots

The production of nanoparticles on an industrial scale requires an approach other than the widely used hot-injection method. In this work, two heat-up methods are applied to nanoparticle synthesis. The induction heating method produces CdSe quantum dots with ultrasmall properties in seconds. Initial flow-through experiments demonstrate that induction heating continuously produces quantum dots. These results are compared with those from microwave synthesis, which produces quantum dots on a longer timescale but provides fast, continuous heating. Both methods can produce quantum dots within seconds because of rapid heating. In addition, different precursors, single source and separate source, give different results, ultimately providing a handle to control quantum dot properties. © Copyright 2018 American Chemical Society

Papanicoloau smear uptake among substance-using mothers in Western Australia

Background: Papanicoloau (Pap) smear screening has helped to reduce cervical cancer rates significantly through the detection of premalignant cells (Bray et al, 2005). Uptake among women who use alcohol and other drugs (AOD) is known to be low (Chau et al, 2002) so they are at increased risk of being under-represented in the adequately screened population. AOD-using women experience disproportionately increased morbidity and mortality from cervical dysplasia and cancer (Nogara et al, 2013). Pregnancy may provide the midwife an opportunity to offer this vital screening test. Objective: The audit investigated Pap smear uptake and results among AOD-using pregnant women. Setting: Pregnant women cared for by an obstetric AOD service based in a tertiary hospital in Perth, Western Australia, were eligible for inclusion in the study. Results: Across a period of 12 months, 333 childbearing-aged AOD-addicted women were audited: 142 had a Pap smear in the previous 3 years; 80 had not had a Pap smear in the previous 3 years; 80 declined a Pap smear; and 31 were either illegible or no record was available. Conclusion: This audit emphasises the importance of Pap smears being offered and followed up among the population of AOD-using pregnant mothers. Encouraging early booking and access to early antenatal care with midwives who are proficient in Pap smear collection is essential in order to provide optimal care
