The demand of groundwater has significantly increased during the past two decades to meet the food and fiber requirements due to constrained surface irrigation water.The groundwater has a major share to grow agriculture in Punjab-Pakistan, which produces more than 90% gains of the country.Beside the importance of groundwater, a major concern in rec
The Skolem problem is a long-standing open problem in linear dynamical systems: can a linear recurrence sequence (LRS) ever reach 0 from a given initial configuration? Similarly, the positivity problem asks whether the LRS stays positive from an initial configuration.Deciding Skolem (or Adapters positivity) has been open for half a century: the bes
The aim of the study is to find out the feasibility of including green manured fallow in specialized sugar beet crop rotations by comparing necessary assessment indicators with their values in a traditional crop rotation with black fallow against the background of unequal fertilization levels.The study was based on the analysis of experimental data
Thermal energy storage in long-distance heating supply pipelines can improve the peak shaving and frequency regulation capabilities of combined heat and power (CHP) units participating in the power grid.In this study, a one-dimensional numerical model was established to predict the thermal lag in long-distance pipelines at different scale levels.Th
