Public transport traffic management systems simulation in Craiova city

[EN] Urban transport is a comprehensive and dynamic mechanism. Therefore, all the problems for improving and reorganization of the system can be examined only in the light of a systemic approach. Currently, public passenger transport is one of the most important branches of the urban development in cities and metropolis. Public passenger transport activity and all the steps taken to improve that activity are considered to be of great social importance. In the current stage of city development, one of the main tasks is to create a public passenger transportation system that is safe, affordable, economical, reliable and environmentally friendly. The important role of passenger transport in the city's economy and achieving important social services to the population, dictates the need to introduce measures in the system that are harmonious, balanced and effective. This can only be done, in the context of current development, only after the system as a whole is tested extensively through special traffic and management software.Dumitru, I.; Matei, L.; Racila, L.; Nicolae, D.

Saturation flow mathematical model based on multiple combinations of lane groups

[EN] The ideal value of the traffic stream that can pass through an intersection is known as the saturation flow rate per hour on vehicle green time. The saturation flow is important in the understanding of the traffic light cycle and from there the understanding the Level of Service. The paper wishes to evaluate through a series of applied mathematical methods the effect of different lane grouping and critical lane group concept on the saturation flow rate. The importance of this method is that it creates a base for a signalized intersections timing plan.Dumitru, I.; Matei, L.; Racila, L.; Nicolae, D. (2016).

Analysis of Patterns and Similarities in Service Tickets using Natural Language Processing

In this paper we propose an approach for classifying documents, embedding documents into feature vectors and using these embeddings for finding similarities between them. Our chosen domain for applying this method is the IT-Service Support branch, where the documents we try to analyse are support tickets and the potential of classifying and finding patterns between tickets is huge for optimizing the service process. We aim to tackle the problem with multiple methods of text classification and recognition, and data analysis, followed by comparison and interpretation of the results. Following our previous work in this field, we propose further means of validating our models, so we can describe and visualize several methods of feature extraction and recognition for service tickets that help the business process for Service Support

MICROBIOLOGICAL CHARACTERIZATION OF SUPPRESSIVE FOREST SOIL FROM ENISALA

Suppressiveness is the property of certain soils to inhibit or limit the development of pathogenic species due to the presence of microbial antagonists.Research has been carried out to characterize the microbial communities in the Calcic Chernozem (WRB) under cultivated forest from Enisala, Tulcea county. The bacterial microflora was dominated by pseudomonads and actinomycetes and fungal species were cosmopolitan, many of them antagonists and strong cellulolytic (Trichoderma, Mortierella, Epicoccum, Aspergillus, Penicillium). Soil suppressiveness was confirmed by the absence of the soil-borne pathogenic species. Mechanisms such as biochemical antagonism and hiperparasitism were evidenced by examination of interaction zone between Trichoderma viride and the test-pathogen Fusarium verticillioides

RESEARCH ON THE ROLE OF MICROBIAL CONSORTIUM IN BIOSYNTHESIS OF HUMIC PRECURSORS BASED ON SECONDARY EXOMETABOLITES

The ability of exometabolites formation by secondary metabolism of edaphicmicroorganisms is genetically determined and antibiotic properties and their biologically activity accompanies this skill, also. Microbial isolates from different soil types and vermicompost were selected based on their ability to excrete soluble secondary metabolites in growth medium, and identified as belonging to the genera Bacillus, Pseudomonas, Lactobacillus, Streptomyces, Fusarium, Aspergillus and Botrytis. The qualitative and quantitative influence of the number of microbial isolates or the type of microbial consortia on the content of secondary exometabolites with a composition close to humic acids precursors has been assessed by circular chromatography analysis, enzymes activities and polysaccharide biosynthesis

The possibilities of using an outline crash sketch in modelling and simulation of accidents

The paper underpins the reconstruction and analysis of a vehicle - motorcycle-biker-assembly collision type by means of a graphical method. The virtual modeling of the traffic accident reconstruction was achieved by complying the traces and the distances identified; hence it was imported and developed the accident scene sketch. Following the numerical processing of the simulation, the vehicles speed during the pre-collision, collision and post-collision phases was determined in graphical form, generating speed and space variation diagrams.This work is published under NOCC (the "Licence").

Creating the Cartographic Database and Informatization of the Systematic Cadastre Works Process

The main objective of this paper is to correlate the current cartographic database with the old one, in the systematic cadastral works. Implementing a GIS and a geodatabase containing the cartographic database is necessary for identifying the buildings in the systematic cadastral works. In order to obtain the actual mappingdatabase, a Phantom 4 PRO drone was used, with a 20 mp resolution camera. For determining the ground reference points there were used two South S82V GPS receivers with double frequency L1, L2, in base-rover radio mode. The existing cartographic database has been taken over from the Cadastre and Land Registration Office and integratedinto the newly created geodatabase. With a unique GIS database, the process of identifying new buildings with old land data is done in a fast and efficient way. The accuracy of the new cartographic database provides greater security identifications, which can be affected even in the office, especially for those owners who have not submittedthe stage of identifying the land. The exploitation of UAV photogrammetric measurements come in support of specialists carrying out systematic cadastre works, especially in the context of the low price per building imposed by the National Agency of Cadastre and Real Estate Advertising

Vitamina D şi riscul cardiovascular: rolul medicului de familie în prevenţia cardiovasculară

Universitatea Ovidius, Constanţa, Universitatea de Medicină şi Farmacie Carol Davila, Bucureşti, Institutul Naţional pentru Sănătatea Mamei şi Copilului Alessandrescu-Rusescu, Bucureşti, Universitatea Bioterra, Bucureşti, cabinet medical individualIntroducere Patologia cardiovasculară cunoaşte în ultimii ani o creştere alarmantă a incidenţei, HTA fiind considerată cea mai frecventă afecţiune în acest context. OMS consideră că bolile cardiovasculare constituie prima cauză de mortalitate în lume. Statisticile arată o creştere a incidenţei, astfel că ”în 2012 au existat 17,3 milioane decese, dintre care 7,3 milioane s-au datorat bolii coronariene, 6,2 milioane au avut un atac cerebral şi 9,4 milioane au avut drept cauză directă HTA”. În acelaşi sens, o analiză a OMS şi a Societăţii Internaţionale de HTA, realizată în 2014, a scos în evidenţă faptul că HTA constituie ”cel mai important factor de risc pentru deces şi dizabilitate la scară mondială” şi ”cel mai răspândit factor de risc cardiovascular de pe glob”. În România, prevalenţa HTA este foarte mare – aproximativ 7 milioane de persoane sau 40% din populaţia ţării. De asemenea, se constată apariţia bolii la vârste tinere, sub 40 de ani, ceea ce constituie un adevărat semnal de alarmă. Este important de precizat faptul că studiile au demonstrat că există o relaţie de interdependenţă clară între HTA şi riscul cardiovascular, uneori chiar independent de alţi factori de risc. Astfel, rolul medicului de familie este extrem de important, HTA fiind practic cea mai frecventă formă de boală cronică, monitorizată în cabinet. Prevenţia este esenţială, medicina de familie având un rol foarte important, fiind singura specialitate care are ca obiect de activitate şi prevenţia. Depistarea la timp a valorilor crescute de TA şi a celorlalţi factori de risc cardiovascular, tratarea corecta, prevenirea afectării organelor-ţintă şi a complicaţiilor, evaluarea corectă a riscului cardiovascular sunt obiectivele pe care trebuie să le aibă medicul de familie în abordarea şi managementul pacientului cu HTA şi risc de boală cardiovasculară. Obiective Există însă o multitudine de necunoscute încă în această patologie, cu identificarea a ”noi” factori de risc, ce ar putea avea rol în apariţia HTA şi a patologiei cardiovasculare, în determinarea unui risc cardiovascular crescut. Unul dintre aceşti ”noi” factori de risc cardiovascular este considerat, în ultimii ani, deficitul de vitamina D. Relaţia dintre vit. D şi riscul cardiovascular face obiectul mai multor studii în ultimii ani, dovedindu-se faptul că există o legătură directă între deficitul de vit. D şi un risc cardiovascular crescut. Material şi metodă de cercetare Am efectuat un studiu prospectiv, desfăşurat între anii 2011 şi 2017, pe un lot de 316 pacienţi din lista proprie de capitaţie, care au fost diagnosticaţi cu HTA, după o monitorizare de trei luni de zile ale valorilor TA (dintr-un lot total de 692 pacienţi). Parametrii monitorizaţi la toţi pacienţii incluşi în studiu au fost: greutate, înălţime, circumferinţa abdominală, indicele de masă corporala,Tensiunea arterială, frecvenţa cardiacă, colesterol total, HDL, LDL, non-HDL colesterol, trigliceride, glicemie, uree, creatinina serică-RFG, acid uric, fibrinogen, VSH, hs-CRP (ca marker al riscului cardiovascular), calciu seric, osteodensitometrie. La 146 de pacienţi din lotul de 316 (F-106 şi B-40) s-a dozat şi vit. D (25-hidroxi vitamin D). Criterii de includere pentru acest studiu au fost: vârsta de 35-65 ani, prezenţa HTA+/-BCV, DZ, obezitate, depresie. Criterii de excludere: vârsta <35 ani şi >65 ani, prezenţa osteoporozei/osteopeniei în tratament, hipocalcemie sau afecţiuni tiroidiene în tratament. Valoarea normală a vit. D (25 hidroxi) a fost considerată >30 ng/ml (conform Societăţii Europene de Endocrinologie). Rezultate obţinute şi discuţii Cercetările efectuate în studiu au elucidat mai multe aspecte: • Valori mici (<10 şi 10-20 ng/ml), respectiv deficitul sever sau moderat de vit. D, se atestă mai frecvent la femei decât la bărbaţi. • Grupele de vârstă 41-50 de ani şi 51-60 de ani sunt cele mai expuse, mai ales la femei. • Obezitatea (evaluatăprinIMC,CA) este înrelaţie invers proporţională cu nivelul de vit. D (IMC şi CA crescute – vit. D scăzută), IMC este mai crescut la femei decât la bărbaţi, grupele de vârstă 41-50 de ani şi 51-60 de ani fiind mai expuse. • Relaţia dintre hs-CRP şi vit. D. Riscul cardiovascular moderat sau crescut (conform datelor şi valorilor de laborator) este prezent la peste 50% din pacienţii din lotul studiat. Se evidenţiază o relaţie invers proporţională între vit. D şi valoarea hs-CRP (vit. D scade, riscul cardiovascular creşte). • Corecţia deficitului de vit. D prin administrarea acestei vitamine, conform ghidurilor Societăţii Europene de Endocrinologie, a arătat o normalizare a valorilor – 25 (OH) vit. D, după 8 săptămâni de tratament. • La pacienţii care prezentau variabilitate a TA s-a obţinut o stabilizare a valorilor şi o scădere a TA sistolice cu 10-15 mmHg la 82% din pacienţii cuprinşi în studiu şi a TA diastolice cu 5-10 mmHg la 35%. Exista o seama de limite pe care studiile viitoare ar trebui sa le depăşească: încă mai este nevoie de dovezi care să explice relaţia dintre deficitul de vitamina D şi boala cardiovasculară, rolul suplimentării cu această vitamină în protecţia cardiovasculară. Concluzii Astfel, se poate considera că vitamina D are un rol important în organism, deficitul acesteia este foarte frecvent în populaţie şi ar putea fi considerat factor ”nou” de risc cardiovascular, iar grupa de vârstă 40-50 de ani are cele mai multe variabile şi este cea care poate fi abordată cel mai bine pentru prevenţie

CONSIDERATIONS CONCERNING THE VALORIZATION OF THE JUICE OBTAINED FROM SUGAR SORGHUM STALK FROM ALCOHOL

 With a high production per hectare, sugar sorghum is a high value technical plant for farmers because from an average production of 70-80 t/ha, a high quantity of juice can be obtained, which can be used as such in the food industry (natural sweetener) or processed for the purpose of obtaining alcohol. The alcohol has a higher value/liter, can be stored more easily and its uses are multiple: in the food, pharmaceutical, chemical industry, etc

GENERAL CONSIDERATIONS CONCERNING THE EFFECTS OF ELECTRO-OSMOSIS ON DECREASING THE FORCES AND THE ENERGY NEEDED FOR TILLING THE SOIL

Electro-osmosis principle consists in the application of a direct current voltage for an anode-cathode system introduced into soil. The effect of this system consists of the mobilization of water particles from the soil and their transport, in a very short time, from the anode to cathode. The soil water transported from the anode to cathode, on the tool-soil contact surface, in consequence, will produce a lubrication of the active surface and thereby a considerable reduction of the friction forces and implicitly of the energy necessary to move the tool through the soil
