Most infectious diseases follow a seasonal cycle that allows germs to spread and infect humans. An abrupt climate change can promote infections in the winter. The study aims to determine winter disease prevalence in Narayanganj. To learn about seasonal illness risk factors, management, treatment, and other implications. People in Narayanganj city were interviewed using a self-designed English questionnaire. The questionnaire asked about demographics, education, socioeconomic level, winter sickness awareness, etc. Our of total 200 participant population male respondents were 59% and female 41%, among them the prevalence of diseases are allergy 59%, stomach flu 76%, common cold 345, influenza 17%, skin disease 11%, asthma 21%, croup 6% and sore throat 14% which is counted respectively of total surveyed participants number.
The Aalborg Centre for Problem Based Learning in Engineering Science and Sustainability is a category 2 centre under the auspices of UNESCO, approved by the General Conference of UNESCO in November, 2013. The Aalborg Centre was formally launched on May 26, 2014.
Globally, there is a need for educating engineers and scientist who can participate in development of sustainable innovations. This will imply a reform of engineering and science education to educate engineers with employable knowledge and skills.
The Aalborg Centre contributes to a reform strategy to higher education by combining Problem and Project Based Learning (PBL), Engineering Education Research (EER) and Education for Sustainable Development (ESD). This is a unique combination of Research & Development areas that are mutual dependent and complementary.
A driving force for the Aalborg Centre is the exemplary practice Aalborg University has for both PBL and integration of sustainability in engineering and science education. Since 1974, Aalborg University has practised PBL as the pedagogical learning methodology during the entire study period. Aalborg University has also the objective for all students to gain sustainability knowledge, skills and competences as a result of a series of sub-learning outcomes throughout the education.
The Aalborg Centre encompass the UNESCO Chair in Problem Based Learning (UCPBL) which was established in 2007 and is renown for its accomplishments in supporting the development of Problem Based and Project Based Learning in Engineering Education. The Obel Family Foundation has kindly offered to sponsor the UNESCO Centre in PBL for a period of five years with the main task to lead the Aalborg Centre.
Control of capillary flow through porous media has broad practical implications. However, achieving accurate and reliable control of such processes by tuning the pore size or by modification of interface wettability remains challenging. Here we propose that the liquid flow by capillary penetration can be accurately adjusted by tuning the geometry of porous media. Methodologies: On the basis of Darcy’s law, a general framework is proposed to facilitate the control of capillary flow in porous systems by tailoring the geometric shape of porous structures. A numerical simulation approach based on finite element method is also employed to validate the theoretical prediction. Findings: A basic capillary component with a tunable velocity gradient is designed according to the proposed framework. By using the basic component, two functional capillary elements, namely, (i) flow accelerator and (ii) flow resistor, are demonstrated. Then, multi-functional fluidic devices with controllable capillary flow are realized by assembling the designed capillary elements. All the theoretical designs are validated by numerical simulations. Finally, it is shown that the proposed concept can be extended to three-dimensional design of porous media
