Role of Mineral Nutrients in Plant Growth Under Extreme Temperatures
Food productivity is decreasing with the drastic increase in population, while it is expected that the global population will be nine to ten billion in 2050. Growth, production, and development on whole plant, cell, and subcellular levels are extremely affected by environmental factors particularly with the extreme temperature events (high- or low-temperature stress). Increase in the fluidity of lipid membrane, protein accumulation, and denaturation are the direct effects of high temperature on a plant. Membrane integrity loss, protein deprivation, protein synthesis inhabitation, and inactivation of mitochondrial and chloroplast enzymes are the indirect effects of high temperature. Similarly, the oval abortion, alteration of the pollen tube, reduction in fruit set, pollen sterility, and flower abscission are the consequences of low temperature at the time of product development, which in turn lowers the yield. The judicious nutrient management is essential for improving the plant nutrition status to mitigate the drastic effects of temperature stress as well as for sustainable plant yield under extreme temperature events, because nutrient deficiency results in growth and development problems in 60% cultivars worldwide. Additionally, effective nutrient management increases the temperature stress tolerance in plants. Therefore, the appropriate nutrient application rates and timings are imperative for alleviating the heat stress in plants and can serve as an effective and decent strategy. To minimize the contrasting effects of the environmental stresses, particularly heat stress, several examples of the supplemental applications of N, P, K, Ca, Mg, Se, and Zn are given in detail in this study, to observe how these nutrients reduce the effects of temperature stress in plants. This study concluded that judicious nutrient management minimizes the heat stress and increases the growth and yield of plants

The LHCb Upgrade I
Abstract
The LHCb upgrade represents a major change of the
experiment. The detectors have been almost completely renewed to
allow running at an instantaneous luminosity five times larger than
that of the previous running periods. Readout of all detectors into
an all-software trigger is central to the new design, facilitating
the reconstruction of events at the maximum LHC interaction rate,
and their selection in real time. The experiment's tracking system
has been completely upgraded with a new pixel vertex detector, a
silicon tracker upstream of the dipole magnet and three
scintillating fibre tracking stations downstream of the magnet. The
whole photon detection system of the RICH detectors has been renewed
and the readout electronics of the calorimeter and muon systems have
been fully overhauled. The first stage of the all-software trigger
is implemented on a GPU farm. The output of the trigger provides a
combination of totally reconstructed physics objects, such as tracks
and vertices, ready for final analysis, and of entire events which
need further offline reprocessing. This scheme required a complete
revision of the computing model and rewriting of the experiment's
software.</jats:p
