Coastal flooding has been a significant hazard in Hong Kong. Influenced by climate change, extreme coastal events have frequently observed the past decades. Nowadays, real estate sector increasingly recognized significance of managing future risks. However, there are few relevant Geographic Information System (GIS)-based assessment tools and studies about scenarios. Against this background, stu...
Understanding the factors related to teacher burnout helps in creating schools which foster teachers’ job satisfaction and delivery of high-quality education. We studied its three subdomains across several teacher-, student-, organisation-level variables, including category, class size, number students with support needs, attitudes towards inclusive education, availability support. The particip...
BACKGROUND The impact of climate change and particularly increasing temperature on mortality has been examined for three cities in the province of Québec, Canada. METHODS Generalized linear Poisson regression has been fitted to the total daily mortality for each city. Smooth parametric cubic splines of temperature and humidity have been used to do nonlinear modeling of these parameters. The m...
تغییرات خصوصیات بارش تحت تاثیر تغییر اقلیم شامل تغییر تعداد روزهای مرطوب، مدت بارش، شدت بارش و هم چنین تغییر در مقدار بارش میباشد. هدف این تحقیق تعیین اثر تغییر اقلیم بر مقدار و شدت باران در سواحل جنوبی دریای خزر است. به همین منظور مولفههای بارش در سه دوره (2030-2011)، (2065-2045) و (2099-2080) در شمال ایران با استفاده از پیش بینیهای مدل چرخش عمومی جوHadCM3 ، سناریوی انتشارA1B و همچنین مدل ...
با توجه به گسترش رشته کوههای زاگرس در بخشهای غرب و جنوب غرب کشور، پوشش برفی این رشته کوهها یکی از منابع بزرگ تامین آب در حوزههای آّبریز دز، کرخه و کارون میباشد این در حالی است که تغییر در سطح پوشش برف در دهههای آینده میتواند روانآب حاصل از ذوب برف که نقش عمدهای در تأمین پتانسیل آبی در این مناطق را دارا میباشد، دستخوش تغییراتی قرار دهد. در پژوهش حاضر نوسان روانآب حاصل از ذوب برف...
Elisabeth Hamin, for their guidance in constructing the project and for posing important questions that helped drive the design of the project. I would especially like to thank Tim Randhir for working with me to build the model. I would also like to thank Nancy Sammons and Raghavan Srinivasan for their extensive support in troubleshooting problems with the model. Their willingness to take time ...
This paper presents the assessment of climate change impacts on some critical water management issues such as reservoir storage and hydroelectric production. Two equilibrium scenarios (UK Meteorological Office High Resolution model, UKHI and Canadian Climate Centre model, CCC) referring to years 2020, 2050 and 2100 and one transient scenario (UK High Resolution Transient output, UKTR) referring...
Climate models generally project an increase in the winter North Atlantic Oscillation (NAO) index under a future high-emissions scenario, alongside precipitation northern Europe and decrease southern Europe. The extent to which forced NAO trends are important for European their uncertainty remains unclear. We show using Multimodel Large Ensemble Archive that plays small role mean projections 20...
This work describes the construction of an ultra-compact narrowband fiber laser source for coherent anti-Stokes Raman scattering microscopy tags, that is, addressing resonances deuterated molecules and alkyne tags in spectral range from 2080 to 2220 cm?1. A fast electronically tunable cw seed based on a semiconductor optical amplifier (SOA) emitting around 1335 nm has been employed four-wave mi...
India is the second largest producer of potato in the world. The Indo-Gangeticplains (IGP) is the main potato growing region accounting for almost 85% of the1.8 Mha under the crop in India where it is grown as an irrigated crop during thewinter season. Since IGP is in sub-tropical plains, duration of the thermally suitablewindow is the main determinant limiting yields. Hence the impact of clima...
