    Ethnobotanical researches reflect the conventional learning of a region. Over the previous decade, medical plants which used for healing indigenous people has become a significant notion among the people and impacted improvement of scientific and ethnobotanical knowledge and investigations of eliminating health problems. A public database has been based on data assembled from various verifiable sources, including journals, travel records, and treatises on therapeutic plants, composed by explorers, botanists, doctors, researchers who went to the nations during the most recent three centuries. In addition, ethnobotanical data depicted in chronicled natural accumulations and in Ancient and Medieval writings from the inquired district have been incorporated into the database. The databases have to be sufficiently adaptable to illustrate a valuable tool for analysts who need to store and analyze present and past ethnobotanical data from the researched location. The ethnobotanical researches are improved in Azerbaijan day by day. The database is used for informing people about some national plants which are growing in the different region of Azerbaijan. The ethnobotanical databases from different countries are analyzed in this article.There are used some special methods for comparing the differences among these databases as data mining and text mining. As a first step the suitable databases are gathered for our investigation, then are defined the best information systems that are used in many countries\u27 biologists and scientists and the end is observed advantages and disadvantages of all existing ethnobotanical databases which we researched. The features of information systems are evaluated. The results demonstrated each of databases has its very own quality, but none has turned a standard form for universal research. The reason is very basic: none of these databases enable specialists to include their own information. There is also illustrated sample structure, main tables and key components of the ethnobotanical database.The obtained results, while a few ethnobotanical databases existing, none are satisfactory answers for worldwide work, and none enable analysts to include their very own information. There is a need brought together all essential properties of existing databases, and creating a free database that encourages ethnobotanical research. Due to the rise and quick improvement in the field of data advances, it has now turned out to be conceivable to digitize, oversee and make ethnobotanical information accessible to a more extensive gathering of people

    A Comprehensive Severity Analysis Of Large Vehicle Crashes

    Get PDF
    The goal of this thesis is to determine the contributing factors affecting severe traffic crashes (severe: incapacitating and fatal - non-severe: no injury, possible injury, and non-incapacitating), and in particular those factors influencing crashes involving large vehicles (heavy trucks, truck tractors, RVs, and buses). Florida Department of Highway Safety and Motor Vehicles (DHSMV) crash reports of 2008 have been used. The data included 352 fatalities and 9,838 injuries due to large vehicle crashes. Using the crashes involving large vehicles, a model comparison between binary logit model and a Chi-squared Automatic Interaction Detection (CHAID) decision tree model is provided. There were 13 significant factors (i.e. crash type with respect to vehicle types, residency of driver, DUI, rural-urban, etc.) found significant in the logistic procedure while 7 factors found (i.e. posted speed limit, intersection, etc.) in the CHAID model. The model comparison results indicate that the logit analysis procedure is better in terms of prediction power. The following analysis is a modeling structure involving three binary logit models. The first model was conducted to estimate the crash severity of crashes that involved only personal vehicles (PV). Second model uses the crashes that involved large vehicles (LV) and passenger vehicles (PV). The final model estimated the severity level of crashes involving only large vehicles (LV). Significant differences with respect to various risk factors including driver, iii vehicle, environmental, road geometry and traffic characteristics were found to exist between those crash types and models. For example, driving under the influence of Alcohol (DUI) has positive effect on the severity of PV vs. PV and LV vs. PV while it has no effect on LV vs. LV. As a result, 4 of the variables found to be significant were similar in all three models (although often with quite different impact) and there were 11 variables that significantly influenced crash injury severity in PV vs. PV crashes, and 9 variables that significantly influenced crash injury severity in LV vs. PV crashes. Based on the significant variables, maximum posted speed, number of vehicles involved, and intersections are among the factors that have major impact on injury severity. These results could be used to identify potential countermeasures to reduce crash severity in general, and for LVs in particular. For example, restricting the speed limits and enforcing it for large vehicles could be a suggested countermeasure based on this study

    Immuun Etiquette: omgang met vorm in context

    Mijn eerste kennismaking met de immunologie, de leer van het afweersysteem, was als student Medische Biologie aan de VU in Amsterdam. Ik kreeg colleges in dit keuzevak van professor Henk Langevoort. Hij was een uitstekend docent en bovendien viel mij sterk op hoe hij als voorzitter bij lezingen ook als een beminnelijk soort wetenschappelijk gastheer optrad en zo de discussie stimuleerde. Dat sprak mij wel aan, zo een hoogleraar te zijn, als ver en onbereikbaar ideaal. Langevoort was een van de grondleggers van de Nederlandse traditie Histofysiologie van de immuunrespons. Dat laat zich kort omschrijven als: hoe werken de afweerreacties in de intacte weefsels. Vandaag zal ik u onder meer tonen hoe die traditie in het werk van onze groep wordt voortgezet. De immunologie als vakgebied is voortgekomen uit een groot en overrompelend succes, namelijk effectieve vaccinatie die beschermt tegen tal van infectieziekten zoals polio en pokken. Jaarlijks worden miljoenen levens gered door toepassing van een immunologisch principe, ontwikkeld nog lang voor het vak zelf bestond.Rede Uitgesproken bij de aanvaarding van het ambt van bijzonder hoogleraar Immuunregulatie aan het Erasmus MC, faculteit van de Erasmus Universiteit Rotterdam op vrijdag 12 mei 200

    Cutting edge technologies in chronic inflammation research

    Get PDF
    This concise review provides the broad background and selection from the literature for a Keynote lecture at EHSF 2022 on state of the art technologies in inflammation research, with an emphasis on disease of the skin and the nervous system. The value of ex vivo skin explant models is discussed, as well as the innovative use of animal models, wherein the crucial roles of antigen experience and "wild" microbiota are emphasized. Spectral flow cytometry allowing large surface marker panels to be explored is touched upon, as well as multiplex technology for cytokines and other analytes important for inflammation and tissue damage. Single-cell sequencing and in situ transcriptomics (spatial profiling) now provide exciting granular information on functional cell subsets, interactions and plasticity. A selection of novel research and diagnostic tools for antibodies against linear peptides or gangliosides is presented. Finally, the review discusses a new anti-inflammatory strategy against skin inflammation with a panel of protease inhibitors derived from the protein fraction of industrial starch potatoes

    In this study, series of small scale laboratory pull-out tests were conducted on anchors embedded in sand. Model tests were performed in a test box. The effects of embedment ratioof anchor plates and relative density of sand on uplift capacity behaviour were investigated.Also numerical analyses of the test models were carried out using the finite element package Plaxis. Based on the results, it can be concluded that the embedment ratio of anchor plates and relative density of sand are main parameters that affect the uplift capacity of anchor plates. Atthe end of the study, the results of experimental study were also compared with the results of numerical solutions

    In this study, the induced vertical soil stress values occuring along with horizontal surfaces at predetermined depths of the shallow foundations on sandy soils were investigated by model tests. In the model tests pressure transducer was used to measure the stresses.Circular foundations at different size were used in the model tests and the size effect were investigated. As a result of this study, the size effect at circular foundations wasn't found tobe an important factor on stress distribution of sandy soils
