Abstract

Precipitation data is of utmost importance to carry out many hydro-meteorological studies. Observed warming over several decades has been linked to changes in the large-scale hydrological cycle such as: increasing atmospheric water vapour content, changing precipitation patterns, intensity and extremes, reduced snow cover and widespread melting of ice, and changes in soil moisture and runoff. Precipitation changes show substantial spatial and inter-decadal variability. General Circulation Models (GCMs), representing physical processes in the atmosphere, ocean, cryosphere and land surface, are the most advanced tools currently available for simulating the response of the global climate system. Recent interest in global warming has also increased concerns about the possible changes in rainfall amount including floods and drought patterns. This study is based on statistical downscaling, which provide good example of focusing on predicting the rainfall using the input of coarse GCM outputs. In this study, we have used GCM outputs for predicting the rainfall. It is obtained from the study that predicted rain values are higher for the first 30 years in compared to remaining prediction periods. The result has shown that winter rainfall may highly decrease in compared to monsoon, post monsoon and pre-monsoon seasons

Abstract

Aims: This study aimed to provide more information about the influence of Coronavirus Disease2019 (COVID-19) on infected individuals. The symptoms, conditions, and treatments used may be served as important clues to find out potential medications.
Materials & Methods: Various current papers were reviewed, and the findings were summarized. In addition, other diseases such as severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS), which have similar causes or symptoms in patients, were investigated.
Findings: The most common symptoms in infected patients were fever (98%), dry cough (76%), and dyspnoea (55%). Mechanical ventilation was the main supportive treatment for ICU patients, and the mortality rate of patients with chronic diseases in the intensive care unit (ICU) was high (55%). The virus is highly contagious compared to the previous Betacoronaviruses causing epidemic, but its mortality rate is lower so that most of the infected patients studied had minor symptoms or were asymptomatic. Several treatments, such as antiviral agents and antimalarial drugs, are presently being proposed and tested, but none have yet been proven to be effective.
Conclusions: Seniors and patients with chronic diseases are at higher risk of COVID-19 induced severe consequences and mortality. Currently, supportive treatment is the mainstay for severely ill patients.

Abstract

Salt-induced changes in the accumulation pattern of seed proteins were studied in salt-sensitive (MI-48) and tolerant (CSR-10) rice lines. An increase in seed protein content was observed with progress in seed development from 4 to 12 Days After Flowering (DAF) and up to maturity at each salinity level (4, 7, and 10 dS m-1). However, a 10-21, and 14-30% reduction in seed protein was noted when compared at a given developmental stage at all the salinity levels in ‘CSR-10’ and ‘MI-48,’ respectively. Among the four seed protein fractions, the proportion of glutelins revealed an increase (5-9%) in mature seeds of ‘CSR-10’ with a decrease (11-13%) in ‘MI-48’ under increasing salinity levels. Prolamins exhibited a reverse trend in both lines. Albumins and globulins revealed a decreased proportion in 'CSR-10' but an increase in 'MI-48' only at 10 dS m-1 at a given developmental stage. In ‘CSR-10’, the accumulation pattern of the glutelin [Molecular weight (Mr.) 36-40.5 and 19-21.5 kDa] and prolamin (13 kDa) polypeptides was seen similar at the control, 4, and 7 dS m-1 except for the higher concentration of these at later two. At 10 dSm-1, a contradictory pattern of accumulation of these polypeptides was observed. In ‘MI-48’, a completely different trend (earlier and faster accumulation) of the above-mentioned polypeptides was seen at 4 and 7 dS m-1 in comparison to the control from early stages. Prolamin polypeptide (13 kDa) showed a continuous decrease in its concentration at all the salinity levels; more pronounced at 10 dSm-1. Therefore, both lines revealed a different mechanism in response to a given salinity condition.
