rivers and runoff have always been of interest to human beings. in order to make use of the proper water resources, human societies, industrial and agricultural centers, etc. have usually been established near rivers. as the time goes on, these societies developed, and therefore water resources were extracted more and more. consequently, conditions of water quality of the rivers experienced rap...
Objectives: Time-use has become an important field of research in social and medical sciences. Time diary is the most popular method for measuring time-use that has 2 different methods of administration including yesterday and tomorrow diary. The present study aimed to compare these methods of measuring time-use. Methods: This cross-sectional comparative study was conducted on 256 under 5-yea...
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
There have been important changes in the United Kingdom’s (UK) fertility and immigration in the past decade, with a large share contributed by migrants from Poland. A detailed understanding of Polish migrant fertility is lacking, however, because the relevant data are not routinely collected. This paper provides new insights into the fertility patterns of Polish migrants in the UK, and compares...
In recent years, real-time global ionospheric map (RT-GIM) products have been actively developed by the international navigation satellite system (GNSS) service (IGS) and its ionosphere associate analysis centers (IAACs) along with increase of RT-GNSS multi-frequency multi-constellation observations. this study, accuracy consistency three RT-GIM from Chinese Academy Sciences (CAS), Wuhan Univer...
The complexity of advanced in-vehicle systems and level automation provided is currently increasing, making the understanding smart design limitations challenging to a driver. As result, misinterpretation system’s capabilities can be detrimental perceived usefulness usage. personalized real-time driver support concept presented in this paper designed improve driver’s Pilot Assist (PA) increase ...
Visual ship tracking provides crucial kinematic traffic information to maritime participants, which helps accurately predict traveling behaviors in the near future. Traditional models obtain a satisfactory performance by exploiting distinct features from images, may fail when scale varies image sequences. Moreover, previous frameworks have not paid much attention weather condition interferences...
