    No full text
    Social Networks such as Twitter are often used for disseminating and collecting information during natural disasters. The potential for its use in Disaster Management has been acknowledged. However, more nuanced understanding of the communications that take place on social networks are required to more effectively integrate this information into the processes within disaster management. The type and value of information shared should be assessed, determining the benefits and issues, with credibility and reliability as known concerns. Mapping the tweets in relation to the modelled stages of a disaster can be a useful evaluation for determining the benefits/drawbacks of using data from social networks, such as Twitter, in disaster management.A thematic analysis of tweets' content, language and tone during the UK Storms and Floods 2013/14 was conducted. Manual scripting was used to determine the official sequence of events, and classify the stages of the disaster into the phases of the Disaster Management Lifecycle, to produce a timeline. Twenty-five topics discussed on Twitter emerged, and three key types of tweets, based on the language and tone, were identified. The timeline represents the events of the disaster, according to the Met Office reports, classed into B. Faulkner's Disaster Management Lifecycle framework. Context is provided when observing the analysed tweets against the timeline. This illustrates a potential basis and benefit for mapping tweets into the Disaster Management Lifecycle phases. Comparing the number of tweets submitted in each month with the timeline, suggests users tweet more as an event heightens and persists. Furthermore, users generally express greater emotion and urgency in their tweets.This paper concludes that the thematic analysis of content on social networks, such as Twitter, can be useful in gaining additional perspectives for disaster management. It demonstrates that mapping tweets into the phases of a Disaster Management Lifecycle model can have benefits in the recovery phase, not just in the response phase, to potentially improve future policies and activities

    FRIGA, A New Approach To Identify Isotopes and Hypernuclei In N-Body Transport Models

    We present a new algorithm to identify fragments in computer simulations of relativistic heavy ion collisions. It is based on the simulated annealing technique and can be applied to n-body transport models like the Quantum Molecular Dynamics. This new approach is able to predict isotope yields as well as hyper-nucleus production. In order to illustrate its predicting power, we confront this new method to experimental data, and show the sensitivity on the parameters which govern the cluster formation

    Topicality. The metabolic syndrome is pathogenetically interrelated metabolic disorders in the condition of a sick person. A large set of factors is involved in its occurrence. Risk factors include genetic predisposition, overeating, insulin resistance, obesity, bad habits, hypodynamics, stress and unfavorable environmental conditions. First of all, defects of the lipid and carbohydrate metabolism provoke a cascade of genetic, metabolic, hormonal, nervous, inflammatory and other reactions and disorders in cells, tissues and organs, causing the metabolic syndrome and associated diseases, such as diabetes, kidney and gallstone disease, hypertension, platelet hyperaggregation, etc. Therefore, the rational use of synthetic and herbal medicines in the complex correction of these disorders can slow down the development of the metabolic syndrome. Aim. To develop the method for obtaining a dry modified extract from bearberry, study its chemical composition, hypoglycemic and hypolipidemic activity in order to determine the prospects of its use for the correction of the metabolic syndrome. Materials and methods. The study object was a dry extract of bearberry leaves modified with cysteine. HPLC and spectrophotometry were used to analyze the extract obtained. The hypoglycemic and hypolipidemic activity of dry extracts of bearberry was studied in rats with insulin resistance. Results and discussion. The method for obtaining a dry modified extract from bearberry leaves was developed by adding cysteine. Phenologlycoside (arbutin), 2Β phenolic acids (gallic and ellagic), 6Β flavonoids, 8Β saponins were identified in the extract, and their quantitative content was determined. Hyperoside and catechin were dominant among flavonoids, and ursolic acid, uvaol, and lupeol prevailed among saponins. The content of the main groups of phenolic compounds was determined in the extract by spectrophotometry. The introduction of the dry extract from bearberry leaves modified with cysteine has a normalizing effect on metabolic disorders on the background of a high-fructose diet; therefore, it can be a promising agent for the correction of the metabolic syndrome. Conclusions. As a result of the research conducted, a new dry extract from bearberry leaves modified with cysteine has been created. The phytochemical composition, hypoglycemic and hypolipidemic activities of the extract have been studied, indicating the prospects for its use to correct the metabolic syndrome.ΠΠΊΡ‚ΡƒΠ°Π»ΡŒΠ½ΠΎΡΡ‚ΡŒ.

    Anxiety disorders represent one of the most prevalent categories of psychiatric illnesses, affecting individuals regardless of gender, age, or social standing. They result in substantial personal and societal costs. The pursuit of novel pharmacological approaches for treating these disorders is driven by the increasing medical necessity to enhance the effectiveness and safety profiles of anxiolytic medications. Due to the fact that benzodiazepines and their derivatives have anti-anxiety, hypnotic-sedative, antidepressant, anticonvulsant, and muscle relaxant properties, they occupy a leading place in the treatment of anxiety disorders. An essential aspect of investigating the pharmacological activity of new triazolobenziazepine derivatives is assessing their impact on rodent muscle tone and coordination of movements. The aim of the work is to find out the influence of new 1,2,3-triazolo-1,4-benzodiazepine derivatives on the muscle tone of rodents in the β€œvertical grid” test and coordination of movements using the rotarod test. Materials and methods. The objects of the study were 5 new derivatives of 1,2,3-triazolo-1,4-benzodiazepines. Before conducting in vivo experiments, these derivatives were mixed with lactose at a ratio of 1:1000. The β€œvertical grid” test and rotarod test (rotating rod test) were used to reproduce the model of motor behavior of rodents. Results. The presence of a tendency to the manifestation of a myorelaxant effect in the β€œvertical grid” test was established. The indicator of the total duration of detention at the facilities was similar and did not differ significantly in the control and experimental groups at doses of 0.50 mg/kg and 0.75 mg/kg. Derivatives MA-252, MA-253 and MA-254 at a dose of 1 mg/kg reduced the total duration of retention on the vertical grid, which indicates their mild muscle relaxant effect. In the rotating rod test, MA-253 derivative at a dose of 1 mg/kg increased the retention time on the rotarod, which demonstrates greater physical endurance of the animals of these experimental groups. Conclusions. The study’s findings indicated that the 1,2,3-triazolo-1,4-benzodiazepine derivatives did not exhibit an adverse impact on movement coordination. Some of these derivatives demonstrated a mild muscle relaxant effect. These results support the need for further research into their influence on spontaneous motor activity. Additionally, there’s a necessity to determine the dosage regimen, establish an effective dose, and adapt it for human use

    This study shows that Yersinia pestis capsular antigen F1 conjugated to the CS nano-particles demonstrates apparent immunogenic effects. When injected to the test animals it was able to stimulate the production of specific antibodies under smaller antigenic load, it caused activation of the genetic apparatus in the immune system cells, and it stimulated hyperplastic processes in the lymphoid organs. Solutions of CS plus antigens appeared to be stable and caused neither general nor local responses in the test animals; they were easy to make use of, thus demonstrating their potentialities to be exploited as adjuvants in immunologic practices

    We evaluated immunochemical, physical and biochemical properties of Vibrio cholerae 569B INABA protective antigenes, derived on industrial and own-developed bioreactors as well as by technology of its concentration by tangential ultrafiltration. We detected, protease, twinase and. lysophospholipase in all samples. Also, dotimmunoanalysis showed equal concentration, of cholerogen-anatoxine and. O-antigen in all samples too. Using chromatography and. electrophoresis, we found their properties as similar. Thus, we suppose to be possible using developed bioreactor as well as technology of Vibrio cholerae 569B INABA protective antigens concentration by tangential concentration during a process of synthetic oral cholera vaccine production

    We presented the data concerning optimization of presentation and consumer container of anti-rabies immunoglobulin obtained, from horse serum.. During the experiments, ampoules and. flasks were used for primary packaging. They were filled within 5 ml of the preparation of freeze-drying. Comparative analysis of physical, chemical and. biological properties and. molecular parameters of freeze-dried and initial forms of the immunoglobulin. was carried out. Freeze-drying was demonstrated to promote stabilization of its properties and. prevent emergence of fragments and. aggregates during anti-rabies immunoglobulin storage
