Közép–Duna Menti Területi Beruházási Program
Get PDFA 2014-20 közötti beruházási időszakban várhatóan erősödik a városi dimenzió. Az Európai Bizottság új eszközöket javasol a tervezésben és a források hatékonyabb felhasználásában. Megkülönböztetett figyelem irányul az Integrált Városfejlesztési Stratégiákra (IVS), valamint az Integrált Területi Beruházásokra (ITI). Hazánkban 2013-tól a területfejlesztés feladatai az országos szint mellett a megyei önkormányzatok szintjére helyeződött. A városok célszerűen nagyobb és kezdeményező szerepet kell, hogy vállaljanak a területfejlesztési programok kialakításában, azon belül is a helyi és térségi, gazdasági és innovációs potenciál fejlesztésében. A Dunaújvárosi Főiskola kezdeményezésével jött létre a Közép-Duna Mente Integrált Területi Beruházási Program, amely 5 megye közigazgatási területét érinti a Duna mindkét oldalán Érdtől az országhatárig. A beruházási Program épít a térségben működő nagyvállalatok lehetőségeire és igényeire, figyelembe veszi a gazdasági, társadalmi és kulturális potenciálokat és a lehetőségeket, veszélyeket is
Catabolic FDA microbial activity as site-dependent monitoring tool in soils of an industrial town
Get PDFThe degree of soil pollutants in the Dunaújváros area has been monitored regularly at 10 sampling points of the town from the upper 0–20 cm and lower 20–40 cm layers of the soils. The quantity of some organic (PAH, TPH) and inorganic (toxic metal) pollutants were determined by GC-MS and ICP analyzation. Microbial status, such as the total cultivable bacteria (CFU) and total catabolicenzyme activity, measured by fl uorescein diacetate analysis (FDA) were also estimated. The area of the industrial town could be divided into more and less contaminated regions, although the measured pollutants were far below the estimated permissible limits. However, at some of the more polluted soils even triple amounts of contaminants could be measured compared to the less-contaminated sites. Among inorganics the Zn microelement reached the highest levels (average is about 100 mg·kg–1 soil), which could be related to the heavy industrial activity. A positive correlation appeared among the organic and inorganic pollutants and also between the pollutants and the measured enzymatic values. The enhanced FDA activity was found at the most contaminated sites preceding the potential “loss of function” on a long-term basis. The fast and reliable microbial parameter could be suggested as further regular monitoring tool
A lower bound for the number of blocks of t − (v, k, λ) designs with t odd
No full textThe aim of this paper is to give a new combinatorial proof of Fisher’s inequality and to prove that if t is odd, t > 1, ε > 0 and b is the number of blocks of a t − (v, k, λ) design, then b = (1 − ε)(λ 2t − (λ − 1)2t )t2 (t − 1)−t2 vt2 for v = v0

Performance of a cyclone combined with electrostatic precipitator
Get PDFIn the present investigation a cylindrical electrostatic precipitator was built into a cyclone’s outlet tubes, and was tested at various dusts and voltages. It has been found that the penetration (the unremoved fraction of the dust) for the airborne particles (d < 10 mm) in the case of working built in electrostatic precipitator, decreased to 5–10% of the penetration of the (only) mechanical cyclone operation. The penetration data is given at various dusts and voltages. All are proving that the method is working satisfactorily. If the voltage was smaller than the on set voltage of the discharge, the better performance could be observed. It means that with elec-tric fi eld it is possible to utilize the tribo-charge of the dust particles caused by the collision with the wall of the cyclone
A karbon aktivitás számításán alapuló diffúziós modell
Get PDFThe paper deals with the stability of centerline inhomogenity of the continuously cast slabs. The pattern of the centerline segregation was modeled physically by preparing a sandwich structure of steel plates with different levels of carbon and alloying elements. The eligibility of sandwich structured samples for diffusional experiments, i.e. the permeability of the metal-metal boundaries in the samples from diffusional point of view was checked by the comparison of measured and theoretically calculated hardness value for plain carbon steels. Diffusional homogenization experiments were performed and the samples were examined metallographically. The paper deals with the details of mathematical approach including the cross effects between carbon and manganese during the diffusional process
The suicidal linguistic behaviour (conclusions based on the multiple-standpoint analysis of the farewell letters written by 152 suicides)
No full textThe present article deals with farewell letters written by 152 suicides in the Hungarian language. The examples are given in translation into English. The author of the article compares structure, grammar and content of these farewell letters with the general rules of letter writing and classifies them basing on the multiple-standpoint analysis. Key words: suicidal intention, suicide; farewell letter; suicidal communication; linguistic behaviour
Analysis of the effects of finite element approximations or geometry of mesh and type of finite elements does matter
Get PDFE cikkel szeretnénk fölrázni a tervezéssel foglalkozó mérnöki társadalmat. Napjainkban agyakorló tervezõi tevékenységet végzõ mérnökök körében még mindig egyfajta „misztikum”kategóriába esik a végeselemmódszer, ezért szinte kétely nélkül fogadják el azokat a számításieredményeket, amit végeselemes szoftver produkál. A cikkben arra kívánjuk a hangsúlyt helyezni,hogy miképp befolyásolják a számítási eredményeket a választott elemtípusok, valamint a véges-elem-háló különbözõ geometriai kialakításai. Ezt egy konkrét példa alapos és átfogó elemzésénkeresztül tesszük meg. Tapasztalatunk szerint ugyanis éppen e kérdés elhanyagolásából, az erreirányuló figyelem hiányából adódik a mérnökileg már nem elfogadható mértékû hibákat tartalmazószámítások legtöbbje
Network teaching and learning in practice
Get PDFThe pedagogic and methodology studies play an important role in the MA teachertraining in Dunaújváros. Within the frames of these studies – considering that most ofthe students are either practicing teachers or are involved in pedagogical type ofprofessional practice – there are several opportunities to have an insight in others’experiences and to acquaint these. Network experience and knowledge-share – whichhas been implemented within the frames of MOTIVATE project and is ongoing in thenext semester - is a significant part of the handover.This presentation will on one hand introduce those professional areas and issue in whichthere are some new possibilities to use network learning and will also introduce the newteacher role model
Analysis of the biological clock of Neurospora
Get PDFA dynamical system describing the circadian fluctuation of a protein (FRQ) in Neurospora cells is investigated from the bifurcation point of view. The possible phase portraits and local bifurcations are studied. The saddle–node and Hopf-bifurcation curves are determined in the plane of two parameters using the parametric representation method. The number and the stability of the stationary points are determined. Using center manifold approximation we determine the Bautin-bifurcation point numerically
