The consensus algorithm is the core mechanism of blockchain and is used to ensure data consistency among blockchain nodes. The PBFT consensus algorithm is widely used in alliance chains because it is resistant to Byzantine errors. However, the present PBFT (Practical Byzantine Fault Tolerance) still has issues with master node selection that is random and complicated communication. The IBFT consensus technique, which is enhanced, is proposed in this study and is based on node trust value and BLS (Boneh-Lynn-Shacham) aggregate signature. In IBFT, multi-level indicators are used to calculate the trust value of each node, and some nodes are selected to take part in network consensus as a result of this calculation. The master node is chosen from among them based on which node has the highest trust value, it transforms the BLS signature process into the information interaction process between nodes. Consequently, communication complexity is reduced, and node-to-node information exchange remains secure. The simulation experiment findings demonstrate that the IBFT consensus method enhances transaction throughput rate by 61% and reduces latency by 13% when compared to the PBFT algorithm.
Stress is an inevitable part of life. Stress occurs when stressful events of self, environmental, or social origin affect the individual's resilience and threaten to collapse his psychological and physical systems. The stress represents difficulties and obstacles that may exceed the individual's ability to bear them and deal with them, which causes him stress and causes negative effects on his psychological and physical health. Therefore, the current research aimed to identify the negative effects of psychological stress on the psychological and physical health of the individual through the literature that dealt with this topic. It was among the results of the research that one of the negative effects of stresses on mental health is the

يُعدّ التناص أحد تقانات البلاغة الحديثة – الأسلوبية- التي تنهض برقي النص ، بوصفه عنصراً فاعلاً في بلورة المعنى وتناغمه مع قصدية المتكلّم ؛ ممّا يسهم في تواشج علائقية البنية الدلالية للنص وتعاضدها النسقي في تكوينه ؛ لفتح نافذة التأويل عند المتلقي بحثاً عن الدلالات المتغلغلة في البنية العميقة ، وهذا ما بدا واضحاً في متن كتاب (غرر البلاغة) للصابي ، فهو يزخر بنصوص تناصية دينية وأدبية ، تمدّ المعنى بطاقات جمالية م

Международные контакты обусловили интерес к изучению основной формы общения – диалога. Форма диалога в каждом из контактирующих в процессе общения языков должна быть рассмотрена в разных аспектах – не только лингвистическом, но и социолингвистическом и этическом. Это объясняется тем, что в речевой коммуникации необходима как адекватность выражения мысли, так и соблюдение тради
