Population is one of the most important factors for the design of the water supply systems, to know the increasing demand and ensure a continuous supply of water to the consumers. In this present paper, a study has been made on forecasting the population of India using manual calculation, python and C programming. The past population record of India was obtained from the census population records. After collecting the population data, the population at the end of the design period was predicted using various population forecasting methods using Python and C Programming. Any desired population can be forecast by feeding the required data in the program. The source codes for python and C programs are proven to be useful to solve all mathematical calculations faster and with accurate values without any approximation.

Quartz sands have a wide variety of application and play a key role in global economic development. However, the activities of mining and minerals processing have vital positive and negative environmental impacts. The environmental impacts of quartz sand mining in Sudan, particularly in North Kordofan State, around Bara Locality are poorly constrained. This study was designed to provide guidelines for evaluation of potential positive and negative environmental impacts of quartz sand mining activities. The techniques adopted are: (1) field investigations and detailed explanation for the data collection processes. During this stage, the authors visited most of the exposed silica sands to document the impact of large-scale surface mining on the environment and did some activities include; open bit excavations, Trenching, and Auger drilling; (2) Literature review and document analysis from related researches and books dealing with the problem of quartz sand mining worldwide. The outcomes of this research are valuable solutions to rehabilitation of land where soil is excavated and mitigation of positive and negative effects. This research was also meant to develop a database on potential positive and negative impacts of sand mining around Bara Locality.

An experiment on rooting of hard wood cuttings of Bougainvillea glabra cv. Cherry Blossom was conducted in the experimental farm of School of Agricultural Sciences & Engineering, IFTM University, Lodhipur Rajput, Moradabad, U.P. between the months of October to January, 2021. The experiment was laid out in Completely Randomized Design (CRD) with seven treatment combinations. The result showed that the treatment combination of Panchgavya (4%) and Vermiwash (1:5 times dilution) was significantly better than the all other treatments and control with respect to rooting of cuttings like Days to first sprout(15.2), sprouted bud/cutting at 30 DAP (6.0),  sprouted bud/cutting at 60 DAP (4.4), length of longest shoot at 30 DAP (16.4cm), length of longest shoot at 60 DAP (18.7cm), length of longest root at 30 DAP (1.6cm),length of longest root at 60 DAP (2.0cm), no. of leaves/cutting at 30 DAP (13.4),no. of leaves/cutting at 60 DAP  (23.4), survival percentage at 30 DAP (90.8%), survival percentage at 60 DAP (80.0%).
