In this study, species composition, density and biomass of zooplanktons including Rotatoria, Protozoa and Meroplanktons were sampled using Juday net with mesh size of 100 µ at depths of 5, 10 and 20 meters in southern Caspian Sea (Babolsar) in two seasons of cold (Feb. 2015) and warm (June 2015) . This study identified Asplanchna sp. and Synchaeta sp. from Rotatoria, and Balanus sp., Pelecypoda...
OBJECTIVES To identify the meteorological drivers of dengue vector density and determine high- and low-risk transmission zones for dengue prevention and control in Cairns, Australia. METHODS Weekly adult female Ae. aegypti data were obtained from 79 double sticky ovitraps (SOs) located in Cairns for the period September 2007-May 2012. Maximum temperature, total rainfall and average relative h...
Abstract Crowdsourced meteorological observations are becoming more prevalent and in some countries their spatial resolution already far exceeds that of traditional networks. However, due to the larger uncertainty associated with these observations, quality control (QC) is an essential step. Spatial QC methods especially well suited for such dense networks since they utilize information from ne...
this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...
introduction there are significant differences in the spatial distribution of the iran annual precipitation. this is resulted from spatial behavior of precipitation in the one hand and variation in the sources of precipitation on the other. the lack of adequate distribution of meteorological stations and the unavailability of long-term statistics of precipitation makes the analysis of precipita...
Temperature is one of the most important climate variables that many economic and social plans related to its changes. Because of The importance of this issue, this study investigated the changes of it in the province Khuzestan. Meteorological data that used in this study is mean temperature in annual and seasonal timescale. The study area is Abadan, Ahwaz, Dezful and Omidiye stations. For anal...
[1] Detailed simulations, comparisons with observations, and model sensitivity experiments are presented for the August 2011 tropical cyclone Irene and a March 2010 nor’easter that affected the New York City (NYC) metropolitan area. These storms brought strong winds, heavy rainfall, and the fourth and seventh highest gauged storm tides (total water level), respectively, at the Battery, NYC. To ...
Local studies aimed at assessing the impact of climate variability on crop yield at the individual farm level require the use of weather and climate data. These are often collected at points known as meteorological stations. In West Africa, meteorological stations are sparsely distributed and as a result, are often unable to satisfy the data requirements for such studies. One major problem aris...
