Vyacheslav M. Tyutyunnik

The paper explores the research work of one of the youngest winners of the 2010 Nobel Prize in Physics, Konstantin Sergeevich Novoselov (born 23.08.1974). Since 2004 when the single-atom graphene was extracted and the research findings were published for the first time, the graphene breakthrough has been made. The paper focuses on the main milestones of Novoselov’s biography and analyzes his publishing activity between 2004 and 2018. The data confirming the highest number of citation of Novoselov’s publications in the world’s leading scientific journals are presented. Novoselov’s main scientific awards are listed.

Medicinal plants plays a significant role in the pharmaceutical industry. In present scenario, the need is to explore, identify and utilize this new medicinal plant on one hand and, on the other, to help conserve the existing but threatened species of rare medicinal plant.This present research work was carry out for the first time in South India to analyse and estimate the biochemical profiles of various extracts of fresh parts of Gnaphalium polycaulon pers., plant. The biochemical composition such as total carbohydrates, total proteins, total lipids, total phenols, cholesterol, total chlorophylls and reducing sugar, sterols were estimated using the standard procedure in fresh plant material.The biochemical analysis of Gnaphalium polycaulon plant showed the presence of various phytochemicals. The results of the present study supplement the usage of the studied plant which possesses several bioactive compounds and used as food and also as medicine.The results of present studies demonstrated that Gnaphalium polycaulon plant could be a sourceof valuable information and a guideline for the scientists, researchers in India and also all over the world

The annual prize, awarded by the Norwegian Academy of Sciences, bears the name of the famous scientist Niels-Henrik Abel and has a reputation as a Nobel Prize for mathematicians, with its size in terms of money of about $1 million. Since Alfred Nobel, in his will, determined the range of scientific areas for the payment of bonuses that did not include mathematics, the Norwegian mathematician Sofus Lee at the end of his life devoted all his efforts and his international authority to create a foundation for awarding prizes to mathematicians. He wanted to give the award the name of Niels Henrik Abel, also a Norwegian mathematician. The article presents a historical background for the formation of the Abel Prize. The winners of the main mathematical prize for all the years of its existence and their major achievements are shown. Among laureates of the Abel Prize there are outstanding scientists from 11 countries: France, Great Britain, Lebanon, USA, Hungary, Sweden, India, Belgium, Russia, Canada and Israel. Three times the prize was at once awarded to two scientists. And in 2019, for the first time ever the woman – Karen Keskalla Uhlenbeck – professor, American mathematician, became the winner of the prestigious mathematics award.

AbstractSingle-atom catalysts (SACs) are promising candidates to catalyze electrochemical CO2 reduction (ECR) due to maximized atomic utilization. However, products are usually limited to CO instead of hydrocarbons or oxygenates due to unfavorable high energy barrier for further electron transfer on synthesized single atom catalytic sites. Here we report a novel partial-carbonization strategy to modify the electronic structures of center atoms on SACs for lowering the overall endothermic energy of key intermediates. A carbon-dots-based SAC margined with unique CuN2O2 sites was synthesized for the first time. The introduction of oxygen ligands brings remarkably high Faradaic efficiency (78%) and selectivity (99% of ECR products) for electrochemical converting CO2 to CH4 with current density of 40 mA·cm-2 in aqueous electrolytes, surpassing most reported SACs which stop at two-electron reduction. Theoretical calculations further revealed that the high selectivity and activity on CuN2O2 active sites are due to the proper elevated CH4 and H2 energy barrier and fine-tuned electronic structure of Cu active sites.

Objectives: We investigated factors associated with Care Home (CH) discharge following stroke using routinely collected data in unselected patients and assessed the relevance of previous research findings to such patients seen in routine clinical practice. Design: Retrospective analysis of data from the Sentinel Stroke National Audit Programme using univariate analysis and logistic regression. Setting: A large acute and rehabilitation UK stroke unit with access to early supported discharge. Subjects: All patients with stroke treated from 1 January 2014 to 1 January 2017. Main measures: National Institutes of Health Stroke Scale (NIHSS) and modified Rankin Scale (mRS). Results: Of 2584 patients (median age 78 years, interquartile range (IQR) 69–86; 50.6% male; 86.7% infarcts; median admission NIHSS 4, IQR 2–9), 401 (15.5%) died in hospital and 203 patients (7.9%) were permanently discharged to CH for the first time. Most had pre-discharge mRS scores of 4/5. Factors (odds ratios; 95% confidence intervals) associated with CH discharge included age (1.07; 1.05–1.10), incontinence (11.5; 7.13–19.25), dysphagia (2.13; 1.39–3.29), severe weakness (1.93; 1.28–2.92), pneumonia (1.68; 1.13–2.50), urinary tract infection (UTI) (1.70; 1.04–2.75) and depression (1.65; 1.00–2.72). In a subgroup of all patients with a pre-discharge mRS of 4/5, age (1.04; 1.02–1.06), incontinence (4.87; 2.39–11.02), UTI (2.0; 1.09–3.71) and pneumonia (1.59; 1.02–2.50) were the only factors associated with CH discharge. Conclusion: Potentially modifiable variables like incontinence, UTI and pneumonia were associated with CH discharge, particularly in the severely disabled.
