Ecdlysichlamys transylvanica sp. nov. is described and its relations discussed based on microscopic observations and physioloical analises made on natural materials and laboratory static and batch cultures. In laboratory conditions it develops typical feature in biphasic medium, however it grows well in other usual artifical media, too (e.g. Benecke, Witsch, Knop-Pringscheim, Knop-Pringscheim-Felföldy, Kuhl-Lorenzen), in which is reveals many characteristic morphoses (pleomorphism).
Soil biological properties and CO 2 emission were compared in undisturbed grass and regularly disked rows of a peach plantation. Higher nutrient content and biological activity were found in the undisturbed, grass-covered rows. Significantly higher CO 2 fluxes were measured in this treatment at almost all the measurement times, in all the soil water content ranges, except the one in which the volumetric soil water content was higher than 45%. The obtained results indicated that in addition to the favourable effect of soil tillage on soil aeration, regular soil disturbance reduces soil microbial activity and soil CO 2 emission.
A new quasi-geoid model for Hungary was determined by combining gravity data, GPS/levelling and vertical deflections. Reduction of the measurements was performed by using Earth Gravitational Model 2008 (EGM2008) and Shuttle Radar Topographic Mission (SRTM) elevation data sets. Calculation method was Least Squares Collocation (LSC) with self-consistent planar logarithmic covariance model. In the computations the weights of GPS/levelling data were large, in this way normal heights obtained from levelling are consistent with GPS heights and with the quasi-geoid model. Astrogeodetic-gravimetric, pure astrogeodetic and pure gravimetric solutions have been calculated besides the combined solution to investigate the discrepancies among the different models. The combined quasi-geoid model fits to the GPS/levelling data with standard deviation of ±4.9 cm, nevertheless at some GPS/levelling sites large differences were indicated.
Abstract
Basic and applied research and development activities are reviewed in the field of application of nuclear methods in the Hungarian aluminium industry, carried out in the last 25 years. The work surveyed is grouped according to tracer investigations on industrial and laboratory scales, application of nuclear analytical methods and radioactive sources. A complete bibliography of the publications is given.
Abstract
The application of particle acclerators in industrial research is reviewed. An R and D mechanism of nuclear analytical research is suggested to illustrate the driving force that doubles in a couple of years the number of publications almost in every branch of nuclear analytical methods. After a general discussion of particle interactions, the various methods of activation analysis and prompt nuclear methods and their applications are shown.
Abstract
Rat luteinizing hormone /LH/ was labelled with125I by the Chloramine T method.125I-LH, used as tracer in radioimmunoassay, was separated from the labelling reaction mixture by gel filtration. By using the proper protein/radioiodine ratio in the labelling reaction mixture the specific activity of125I-LH was adjusted to 2.5–20.5 MBq 
g–1. The influence of the specific activity on the assay parameters as well as on the tracer stability was investigated.
Abstract
The radioactivities of 26 samples of mushrooms (22 species) have been determined. These samples originated primarily from the park forest near Pestszentl
rinc (Hungary). Samples were taken from different parts of the Pestszentlrinc forest including samples from pine, oak and acacia. Measurements included radionuclides such as40K,134Cs,137Cs,110mAg, total-beta and90Sr. It was found that the uptake of cesium isotopes in mushrooms is higher than in green plants, and Macrolepiota species are especially suitable test organisms to detect the110mAg isotope.
We investigated the HLA-DRB, and DQB polymorphism and haplotypes in RA subjects of Hungarian origin by PCR typing using sequence-specific primers. Molecular subtyping of HLA-DRB1*04 alleles in RA patients showed strongest association with highest relative risk with DRB1*0404. A significantly decreased frequency of DRB1*0403 was observed in patients compared to controls. A significant number of patients carried DR4 haplotypes on DQB1*0302 (54%) relative to DQB1*0301 which was present on 36% of the haplotypes. When compared to controls, the frequency was higher in the latter allele only. Few unique DRB-DQB haplotypes were observed in Hungarian RA patients. In spite of the fact, that the Hungarian population has been isolated linguistically over centuries, a considerable racial admixture has occurred following immigration and invasions, thus the present study confirms in Hungarian patients with RA, previous findings for RA and HLA in European countries.
Colour (L*, a*, b*, h o and chroma), β-galactosidase, polygalacturonase (PG) activity, pectin content, ultrastructure and volatile compounds were determined, in mature green and in yellow ber fruits ( Zizyphus mauritiana Lamk. cv. Umran).The L* did not, but a*, b* and h o significantly differed between mature green and yellow ber fruit. The pectin content and its solubilization (soluble pectin and neutral sugars), the activity of PG was higher in yellow ber fruits and in the outer part of fruits. Activity of β-galactosidase was higher in mature green ber fruits. The cell walls of mature green fruits were usually homogeneous, the density of the middle lamellae decreased in yellow bers, and at the same time, the structure of chloroplastids disintegrated. The aroma of yellow ber is characterized by the presence of even carbon number of ethyl esters from C4 to C14.
The sectorial material transport disorders induced by cutting back were first detected some two decades ago (Brunner, 1976; 1990; Brunner et al., 1996). The pruning of oblique scaffold branches to an upper bud causes one-sided drying up and material transport disorders on the lower side of the branch, leading to the formation of close to horizontal shoots on the lower side of the scaffold branch without any tendency for the branch to become bare, and with a considerable reduction in manual labour requirements. This is the essence of this novel pruning method having a bending effect.
