MezĹ‘gazdasági hulladĂ©k bázison közepes sűrűsĂ©gű gipszkötĂ©sű formatest kompozitok előállĂtása Ă©s kötĂ©smechanizmusának vizsgálata = Manufacturing medium density gypsum bonded moulded composites based on agricultural waste and assessing its bonding mechanism
Gazdaságossági Ă©s technolĂłgiai szempontbĂłl pedig a legkedvezĹ‘bb tulajdonságokat -a már feltárt Ă©s rost formában jelenlĂ©vĹ‘ szalmacellulĂłzgyári hulladĂ©kanyag- a rostiszap mutatott. Mivel elsĹ‘sorban olyan termĂ©k előállĂtását cĂ©loztuk meg, amely lehetĹ‘sĂ©g szerint hulladĂ©kanyagok másodnyersanyagkĂ©nt törtĂ©nĹ‘ felhasználásával kĂ©szĂĽljön Ă©s a szárazĂ©pĂtĂ©sben nyerjen alkalmazást, a figyelmĂĽnket a gipsz mátrix rendszer tanulmányozásának irányába terjesztettĂĽk ki. FeltárĂł munka során ezĂ©rt kĂĽlön hangsĂşlyt fektettĂĽnk a giszkötĂ©sű kompozitok mátrix rendszerĂ©t felĂ©pĂtĹ‘ kĂĽlönbözĹ‘ gipsz alapanyagok, natur -(NAT), fĂĽstgáz- (FGD ill. REA), foszfor- (PHO) Ă©s stuck gipsz (STU)alkalmazásának lehetĹ‘sĂ©gĂ©re. Nedves eljárás: A nedves eljárás legnagyobb elĹ‘nyekĂ©nt a homogĂ©n rost-gipsz rendszer kialakĂtása mellett a gipszkarton lapokhoz közeli tĂ©rfogati sűrűsĂ©gi Ă©rtĂ©keket Ă©s jobb hajlĂtĂłszilárdságot tekintjĂĽk. FĂ©lszáraz eljárás: A fĂ©lszáraz eljárás alkalmazása esetĂ©n vált egyĂ©rtelműen felismerhetĹ‘vĂ© a mĂ©sziszap rostfellazĂtást elĹ‘segĂtĹ‘ hatása, viszonylag magas nedvessĂ©gtartalom (u = 80-125%) alkalmazása mellett. ?Száraz? eljárás: Magasabb rost-gipsz tĂ©nyezĹ‘ (x = 0,24) mellett is megfelelĹ‘ homogenitásĂş, jĂłl kezelhetĹ‘ rost-gipsz keverĂ©k előállĂtását sikerĂĽlt elĂ©rni. Az alacsonyabb vĂz-gipsz tĂ©nyezĹ‘ (w = 0,25-0,30) kedvezĹ‘bb fiziko-mechanikai tulajdonságok kialakulásához vezetett valamennyi laptĂpus esetĂ©ben. A formatestek gyártása terĂĽletĂ©n mĂ©g nemzetközi viszonylatban sem találtunk cellulĂłz ill. papĂrgyári másodnyersanyagok felhasználásával kĂ©szĂĽlt hasonlĂł termĂ©kekre utalást, | From economical and technological viewpoints fiber sludge shows the best prosperities. Since in first place we wanted to create a product that is created by re-using wastes as secondary raw material and will be capable of being used in building constructions, we have widened of sight to study the gypsum matrix system. Because of this, we have done a research with an emphasis on the application of various gypsum material: natural gypsum (NAT), flue gas desulphurisation gypsum (REA), phosphorus gypsum (PHO), stuck gypsum (STU). Wet process: The most important benefit of the wet process is the homogeneous fiber-gypsum structure, the similar material density comparing to the gypsum ?cardboard and the higher bending strength. Semi-dry process: At the semi-dry process it was clear, that the lime sludge supported to loosen the fibers at a relative high moisture content, u = 80-125%. Dry process: Higher fiber-gypsum ratio (x =0,24) with good homogeneity, and good handling behaviour. The low water-gypsum ratio (w = 0,25-0,30) improved the mechanical and physical properties. Gypsum bounded fiber stucco. The material made from fiber sludge, lime sludge and gypsum is a new material among of inorganic bounded stucco materials. There is no indication in the international publication of the utilizations of cellulose or secondary raw material of pulping plants
Worst case bin packing for OTN electrical layer networks dimensioning
The
OTN (Optical Transport Network)
standard, defined by ITU-T Recommendation G.709 and G.872, contains
a flexible digital hierarchy of
ODU (Optical Data Unit)
signals. The ODU hierarchy provides sub-wavelength
grooming in OTN networks, which is necessary for efficient utilization of the high bit rates of optical channels.
When dimensioning the links of a transport network consisting of ODU switches, the packing of lower order ODU
signals into higher order ODU signals needs to be taken into account. These networks are expected to be controlled
by
GMPLS (Generalized MPLS)
, which puts specific constraints on the dimensioning. We assume that there is no
explicit label control and that the
GMPLS control plane is using first-fit strategy for making reservations on a
link
. With these assumptions the link dimensioning problem is defined as deciding how many higher order ODU
component links are required on an OTN GMPLS bundled link for first-fit packing of a given set of lower order
ODU demands, in any order of arrival. The paper provides strict bounds for ODU hierarchy-specific item and bin
sizes. Then, it introduces an extended variant of the dimensioning problem, when lower order ODU connections
which are not controlled by GMPLS are also present

The group has made important progress in the past 4 years in the research topics declared in the research plan. The results have been published in more than 50 journal papers, and have been presented at several prestigious international conferences. The most significant results are the following: a polynomial algorithm has been found for the node-connectivity augmentation problem of directed graphs; considerable progress has been made towards the characterization of 3-dimensional rigid graphs and towards the proof of the molecular conjecture; Hendrickson's conjecture has been proved in 2 dimensions; several new algorithmic results were obtained in matching theory using a novel approach; several theorems characterizing connectivity properties of graphs have been generalized to hypergraphs
Screening and monitoring of the BTK C481S mutation in a real-world cohort of patients with relapsed/refractory chronic lymphocytic leukaemia during ibrutinib therapy
The Bruton's tyrosine kinase (BTK) inhibitor ibrutinib has revolutionised the therapeutic landscape of chronic lymphocytic leukaemia (CLL). Acquired mutations emerging at position C481 in the BTK tyrosine kinase domain are the predominant genetic alterations associated with secondary ibrutinib resistance. To assess the correlation between disease progression, and the emergence and temporal dynamics of the most common resistance mutation BTKC481S , sensitive (10-4 ) time-resolved screening was performed in 83 relapsed/refractory CLL patients during single-agent ibrutinib treatment. With a median follow-up time of 40 months, BTKC481S was detected in 48·2% (40/83) of the patients, with 80·0% (32/40) of them showing disease progression during the examined period. In these 32 cases, representing 72·7% (32/44) of all patients experiencing relapse, emergence of the BTKC481S mutation preceded the symptoms of clinical relapse with a median of nine months. Subsequent Bcl-2 inhibition therapy applied in 28/32 patients harbouring BTKC481S and progressing on ibrutinib conferred clinical and molecular remission across the patients. Our study demonstrates the clinical value of sensitive BTKC481S monitoring with the largest longitudinally analysed real-world patient cohort reported to date and validates the feasibility of an early prediction of relapse in the majority of ibrutinib-treated relapsed/refractory CLL patients experiencing disease progression
Recycling of Impregnated DĂ©cor Paper in Particleboard.
The effect of recycling dried impregnated décor paper in particleboard production wasstudied. The results of these experiments showed that by adding crushed impregnated paper thestrength of the particleboards can be increased or the same board properties can be achieved withreduced amounts of applied adhesive (UF). This waste recycling technology is serving to protect theenvironment, forests and nature. Based on our recommendations (considering also the recent rules andregulations of waste handling) a particleboard company started to recycle their impregnated paperwastes
