Creating Scientific Temperament through Children’s Science Congress in Uttarakhand, India

Science and Technology provide hands-on guidance in every field such as agriculture, medical sciences, health care, innovations, public utility services, internal and external security, education, entertainment; information and technology, etc. The awareness related to science through informing, educating, and sharing knowledge for promoting sustainable development is known as science communication. The basic aim of science popularization is to expose the society and upcoming generations to the virtues of scientific development and to help them understand the science in their daily life and surroundings as well. Motivating school children towards science is an important aim of science communication at the school level. The National Council for Science and Technology Communication (NCSTC), Department of Science and Technology (DST), Government of India, New Delhi has been organizing the “Children’s Science Congress (CSC)” as one of the mega flagship programmes at the block, district, state, and the national level throughout the country since the last 27 years. In the present paper, an attempt has been made to compile the experiences of three consecutive years (2017, 2018, and 2019) of Children’s Science Congress organized by the State Council for Science and Technology. It was categorized under seven themes in 2017, while two themes were merged in 2018 and 2019. A total of 11 districts of Uttarakhand participated in the 25th Children’s Science Congress during 2017, while in 2018 and 2019, all (thirteen) districts participated in the Children’s Science Congress. The total number of child scientists from different districts were found to be diverse – 107, 142, and 138 during the 25th, 26th and 27th Children’s Science Congress of Uttarakhand held in 2017, 2018 and 2019, respectively. In the present paper an attempt has been made to understand the impact of Children’s Science Congress (CSC) for creating scientific temper among child scientists and mentors

An Efficient Human Activity Recognition Technique Based on Deep Learning

In this paper, we present a new deep learning-based human activity recognition technique. First, we track and extract human body from each frame of the video stream. Next, we abstract human silhouettes and use them to create binary space-time maps (BSTMs) which summarize human activity within a defined time interval. Finally, we use convolutional neural network (CNN) to extract features from BSTMs and classify the activities. To evaluate our approach, we carried out several tests using three public datasets: Weizmann, Keck Gesture and KTH Database. Experimental results show that our technique outperforms conventional state-of-the-art methods in term of recognition accuracy and provides comparable performance against recent deep learning techniques. It’s simple to implement, requires less computing power, and can be used for multi-subject activity recognition

Climate Change and the Potential Distribution of an Invasive Shrub, Lantana camara L

The threat posed by invasive species, in particular weeds, to biodiversity may be exacerbated by climate change. Lantana camara L. (lantana) is a woody shrub that is highly invasive in many countries of the world. It has a profound economic and environmental impact worldwide, including Australia. Knowledge of the likely potential distribution of this invasive species under current and future climate will be useful in planning better strategies to manage the invasion. A process-oriented niche model of L. camara was developed using CLIMEX to estimate its potential distribution under current and future climate scenarios. The model was calibrated using data from several knowledge domains, including phenological observations and geographic distribution records. The potential distribution of lantana under historical climate exceeded the current distribution in some areas of the world, notably Africa and Asia. Under future scenarios, the climatically suitable areas for L. camara globally were projected to contract. However, some areas were identified in North Africa, Europe and Australia that may become climatically suitable under future climates. In South Africa and China, its potential distribution could expand further inland. These results can inform strategic planning by biosecurity agencies, identifying areas to target for eradication or containment. Distribution maps of risk of potential invasion can be useful tools in public awareness campaigns, especially in countries that have been identified as becoming climatically suitable for L. camara under the future climate scenarios

Heterogeneity in glacier response in the upper Shyok valley, northeast Karakoram

Glaciers in the Karakoram show long-term irregular behaviour with comparatively frequent and sudden advances. A glacier inventory of the upper Shyok valley situated in northeast Karakoram has been generated for the year 2002 using Landsat ETM+ and SRTM3 DEM as baseline data for the investigations and subsequent change analysis. The upper Shyok valley contained 2123 glaciers (larger than 0.02 km2 in size) with an area of 2977.9 ± 95.3 km2 in 2002. Out of these, 18 glaciers with an area of 1004.1 ± 32.1 km2 showed surge-type behaviour. Change analysis based on Hexagon KH-9 (years 1973 and 1974) and Landsat TM/ETM+ (years 1989, 2002 and 2011) images had to be restricted to a subset of 136 glaciers (covering an area of 1609.7 ± 51.5 km2 in 2002) due to adverse snow conditions. The area of the investigated glaciers, including the 18 surge-type glaciers identified, showed no significant changes during all studied periods. However, the analysis provides a hint that the overall glacier area slightly decreased until about 1989 (area 1973: 1613.6 ± 43.6 km2; area 1989: 1602.0 ± 33.6 km2) followed by an increase (area 2002: 1609.7 ± 51.5; area 2011: 1615.8 ± 35.5 km2). Although the overall change in area is insignificant, advances in glacier tongues since the end of the 1980s are clearly visible. Detailed estimations of length changes for individual glaciers since the 1970s and for Central Rimo Glacier since the 1930s confirm the irregular retreat and advance
