Based on the analyses of landslide spatial occurrence, a regional landslide susceptibility model for the area of Slovenia with medium spatial resolution was calculated. Of 3241 landslides with known locations, 67% were selected randomly but representatively as the learning sub-set and used for univariate statistical analyses (c2) to analyse the landslide occurrence in relation to the precondition factors (lithology, slope inclination, slope curvature, slope aspect, distance to geological boundaries, distance to structural elements, distance to surface waters, flow length and land-cover type). In addition, a relation to the triggering factors (maximum 24-hour rainfall intensity with a return period of 100 years, average annual rainfall, and peak ground acceleration with a return period of 475 years) was assessed. The analyses were performed using a geographic information system – GIS in raster format with 25 × 25 m pixel size. The results of the analyses were later used for the development of a weighted linear susceptibility model where more than 156 000 automatically calculated models with random weight combinations were derived. The landslide testing sub-set (33% of landslides) and representative areas with no landslides were used for the validation of all models developed. The results showed that relevant precondition factors for landslide occurrence are (with their weight in a linear model): lithology (0.33), slope inclination (0.23), land-cover type (0.27), slope curvature (0.08), distance to structural elements (0.05), and slope aspect (0.05).

A GIS+analysis was carried out in a test basin of southern Sicily, the Magazzolo River basin, in order to assess susceptibility conditions to gully erosion phenomena. The linear density of ephemeral and permanent gullies computed within each class of nine environmental variables was used to generate a gully erosion susceptibility map for the area. A validation procedure carried out in order to test the reliability of the adopted method highlighted a clear correlation between the occurrence of gullies and the computed susceptibility levels.

Human biomonitoring, as a tool to identify health risk from environmental exposures, has gained increasing interest especially in the areas of cancer risk assessment and diseases treatment. Chromosome aberrations resulting from direct DNA breakage or from inhibition of DNA repair or synthesis, measured in peripheral blood lymphocytes, have been used successfully in the assessment of health risk associated to environmental genotoxic exposures. A faster but sensitive and reliable method for detection of DNA damage, or DNA repair capacity, might be crucial to many fields from molecular epidemiology and toxicology to preventive and clinical medicine. There are reports that results of DNA measures with the use of single cell gel electrophoresis (SCGE) correlate, on the one hand, with physical measures of genotoxins, and on the other hand, with cytogenetic damage that is a biomarker associated to the alteration of the health risk. This review is based on studies in which exposure to radiation was applied as a challenging treatment and DNA damage induced and repaired was analyzed with the use of the alkaline version of SCGE assay. Results from studies on susceptibilities and repair competence carried out in various groups of exposed workers, controls, and cancer patients (more than 700 donors) show variability between donors both in a response to challenging treatment and in the efficiency of repair process. Influences of the occupational exposures and factors depending on genotypes or life style on cellular capacities are observed. Discussed results suggest that study in vitro with the challenging cells by radiation exposure and measuring, with the SCGE assay, the DNA damage before and after repair, may develop a good biomarker of the individual susceptibility to various genotoxins and exposures (environmental, occupational, therapeutic). Such a biomarker may have a potential use in a molecular epidemiology and preclinical identification.

It has not been possible to transform resistivity models in terms of magnetic field in order to account for variation of giant magnetoresistance (GMR) with external magnetic field, which would have led to determination of material properties. This problem is approached mathematically via variation calculus to arrive at an exponential function that fits observed GMR values. Using this model in free electron approximation, the mean Fermi vector, susceptibility and total density of states of a number of metallic multilayers are determined from their reported GMR values. Susceptibility is found to depend on interface roughness and antiferromagnetic (AF) coupling; thus, it gives qualitative measure of interface quality and AF coupling. Comparison of susceptibilities and GMRs of electrodeposited and ion beam sputtered Co/Cu structures shows that a rough interface suppresses GMR in the former but enhances it in the latter.

The aim of the date was to determine the sensitivity to chitosan ascorbate microaerophilic bacteria isolated from pathological pockets, root canals and apical abscesses. Chitosan was obtained from Antarctic krill. The experiments included 70 clinical isolates and 4 standards strains. The susceptibility of microaerophilic bacteria was performed by means of plate dilution technique in Brucella agar supplemented with 5% defibrinated sheep blood. Inoculum contained 105 CFU per spot. Incubation inoculated agar was performed at 37°C for 48 hrs in microaerophilic conditions. MIC was defined as the least concentrations of chitosan ascorbate that inhibited growth of tested bacteria. The results indicated that 47% of all date bacteria was susceptible to chitosan ascorbate in ranges ≤ 0.01 – 0.5 mg/ml. The most susceptible were the strains of Corynebacterium matruchotii (100%, MIC ≤ 0.01 – 0.5 mg/ml) and the least sensitive strains of Rothia dentocariosa (MIC in ranges 1.0 ˗ ≥ 4.0 mg/ml ).

World-wide, urinary tract infections (UTIs) are an important clinical problem. In such, the most frequently isolated uropathogen is Escherichia coli. In the treatment of uncomplicated UTIs, e.g. cystitis, the widely used antibiotics are nitrofurantoin, trimethoprim/sulfamethoxazole, fosfomycin trometamol or ciprofloxacin, while the treatment of pyelonephritis requires the usage of antibiotics with a broader spectrum of activity, such as cephalosporins of the 3rd and 4th generation, aminoglycosides or even carbapenems. The aim of this study was to assess the susceptibility to aminoglycosides (such as amikacin, gentamicin, netilmicin and tobramycin) of E. coli isolated from UTIs in adult community patients living in Lubelszczyzna. We found that all of the 86 strains of E. coli encountered were susceptible to amikacin. Moreover, the prevalence of susceptibility to tobramycin, gentamicin or netilmicin among the tested strains was found to be 89,5%, 90,7% or 94,2%, respectively. The data obtained in the present study shows the high susceptibility to aminoglycosides of E. coli isolated from the community-acquired UTIS in adults. These data, together with that derived from current literature, indicate that aminoglycosides, when employed in combination therapy with other antibiotics, may still be very useful group of antibacterial agents in the treatment of UTI’s in Poland.

Presented here is a method of interpretation of the results of investigation on susceptibility of coal to spontaneous combustion, the essence of which is to define each test under study with a respective numerical index. Owing to this approach one can determine whether the given coal sample, relative to each other, is more or less susceptible to spontaneous combustion. It was noted that the investigations had been conducted compliance with the prevailing Standard Specification PN-93/G-04558. Indicated has been a difference in the procedure of classification resulting from the proposed method and that currently in use as determined in the PN-93.G-04558 Specification.

In the paper we introduce a general approach to wildland fire risk management that we applied for the Slovensky raj territory. The risk management concept is based on assessment of several risk components: susceptibility in the form of calculation of a priori probability of forest destroying by fire, vulnerability based on calculation of posteriori probability of forest destroying by fire and based on modelling the fire behaviour in FARSITE environment. We also briefly introduce an approach to set the measures to prevent the forest fire occurrence and to manage it to minimize its impacts on human, environment and property (resilience).

The aim of the study was determine activity of chitosan ascorbate against 17 strains of Helicobacter pylori. The strains were isolated from gingival pockets (7 strains), atherosclerotic plaques from carotid and femoral (10 strains). Chitosan was obtained from krill chitin and deacetylation degree was equal 60%. The ratio of ascorbic to chitosan was equal 1. The susceptibility of rods was determined by means of plate dilution technique in Brucella agar with 5% sheep’s blood. The inoculum contained 105 CFU/spot. Incubation was performed in anaerobic jars with Campy Pak (BBL) for 48 hrs. The MIC was interpreted as the lowest concentration of chitosan ascorbate inhibiting the growth of bacteria. The results indicated, that chitosan ascorbate at the lowest concentrations was active against 35% of the strains. The Helicobacter pylori rods isolated from gingival pockets were the highest susceptible than isolated from atherosclerotic plaques.

We report on electron spin resonance (ESR) investigations of a FeVO4 single crystal. Temperature and angular dependences of ESR resonance positions were measured and calculated in temperature range of 35 – 100 K. The spectra show rich angular dependences of the linewidth, the shape and the resonance field. They consist of a single broad line with asymmetric distortion. Due to the low symmetry of the crystal lattice this distortion can be explained by taking into account the influence of non diagonal dynamic susceptibility.

Natural killer (NK) cells are the most abundant lymphocyte population in the decidua. These cells express killer immunoglobulin-like receptors (KIRs), which upon recognition of HLA class I molecules on tropho- blasts may either stimulate NK cells (activating KIRs) or inhibit them (inhibitory KIRs) to produce soluble factors necessary for the maintenance of pregnancy. KIR genes exhibit extensive haplotype polymorphism; individuals differ in both the number and kind (activating vs. inhibitory) of KIR genes. This polymorphism affects NK cell reactivity and susceptibility to diseases, including gynecological disorders. Therefore we ATR-genotyped 149 spontaneously aborting women and 117 control multiparae (at least 2 healthy-born children). Several genotypes (i.e. combinations of various KIR genes) were differently distributed among the patients and control subjects. Differences were observed in the numbers and the ratios of activating to inhibitory KIRs between patients and healthy women: (i) genotypes containing 6 activating KIR genes were less frequent and those containing 6 inhibitory KIR genes were more frequent in patients than in control subjects, and (ii) an excess of inhibitory KIRs (activating-to-inhibitory KIR gene ratios of 0.33 to 0.83) was associated with miscarriage, whereas ratios close to equilibrium (0.86-1.25) seemed to be protective. In addition, the results suggest for the first time that sporadic and recurrent spontaneous abortions as well as miscarriage in the presence or absence of autoantibodies may have different KIR genotypie backgrounds.

The paper presents the results of plot experiments on susceptibility of 4 cultivars of fiber flax: Alba, Belinka, Nike and Wiko to broad-leaved weed herbicides (chlorsulfuron, bentazon + MCPA) and graminicides (haloksylop-R, chizalofop P, and setoxidim), used as single or mixtures. The experiments were conducted on two soil suitability complexes in the years 1994-1996. The cultivars Alba and Wiko were more susceptible to herbicides than Nike and Belinka. More susceptible Alba and Wiko showed faster phenological development as compared to two other cultivars, especially in the first period of growing season (from germination to the stage of fast growth). Herbicides had more phytotoxic effect on flax plants on light soil than on other ones. The most phytotoxic effect on tested cultivars, leading to a reduction of scutched fiber yield, was observed for the mixture of haloksylop-R + chlorsulfuron and bentazon + MCPA followed by setoxidim at 7-day interval. Higher yields of most flax cultivars were observed when flax was sprayed with chlorsulfuron herbicides followed by one of the tested graminicides (haloksylop-R, chizalofop P or setoxidim) after seven days from application of chlorsulfuron. The cultivar Nike has been found to be the most resistant to tested herbicides. Application of chemical methods of weed control for cultivation of this cultivar resulted in an increase of long yield of scutched fiber. The herbicides tested in the experiment usually had a beneficial effect on the quality of flax scutched fiber, especially in case of Alba and Wiko cultivars.

Odmiany Alba i Wiko były bardziej wrażliwe na herbicydy niż odmiany Nike i Bielinka. Odmiany wrażliwe charakteryzowały się szybszym wzrostem w początkowym okresie wegetacji. Herbicydy wykazały większą fitotoksyczność na rośliny lnu na glebie lekkiej. Największy ujemny wpływ fitotoksyczny na odminy lnu oraz redukcja włókna długiego wystąpiła po zastosowaniu mieszaniny herbicydów: chlorsulfuronu + haloksylop-R i bentazonu + MCPA i zastosowaniu 7 dni później setoxidimu. Największy plon uzyskano po zastosowaniu chlorsulfuronu a po 7 dniach graminicydów (haloksylop-R, chisalofop P i setoxidimu). Odmiana Nike okazała się najbardziej odporna na badane herbicydy. Badane herbicydy miały korzystny wpływ na jakość włókna w słomie lnu, szczególnie miało to miejsce w odmianach Alba i Wike.

During our study we examined 19 most popular Polish potato cultivars. Susceptibility of tubers to bacterial infection was assessed by two methods: direct injection of bacterial suspension into tuber tissue and clay-inoculation method. The cultivars were divided into three groups: tolerant, relatively susceptible and susceptible. Elida, Bila and Vistula proved to be the most susceptible potato cultivars whereas Ekra and Mila the most resistant. Some of the cultivars such as Oda had resistant peel and susceptible tissue. Therefore during storage of Oda-like cultivars healthy and undamaged tubers are so important.

Najważniejszą rolę w ograniczaniu chorób bakteryjnych odgrywa profilaktyka, między innymi stosowanie odmian odpornych lub wykazujących wysoką tolerancję w stosunku do patogena. Nasze badania objęły 19 powszechnie uprawianych w Polsce odmian ziemniaka. Ocenę podatności bulw ziemniaka na infekcję bakteryjną oraz gnicie przeprowadzono dwiema metodami: metodą powierzchniowej inokulacji przy pomocy gliny zawierającej bakterie oraz metodą iniekcji miąższu zawiesiną bakteryjną końcówkami pipet. Na podstawie uzyskanych wyników badane odmiany zostały zaliczone do trzech grup: tolerancyjne, średnio wrażliwe i podatne. Najwrażliwszymi odmianami okazały się Elida, Bila i Vistula, zaś najodporniejsze były Ekra i Mila. Niektóre odmiany, takie jak np. Oda, charakteryzowały się odporną skórką i podatnym miąższem. W ich przypadku szczególnie ważne jest więc przechowywanie zdrowych i nieuszkodzonych mechanicznie bulw. Opisane badania mogą być wykorzystane przy doborze odmian ziemniaka w uprawie w zależności od warunków klimatycznych, a także w przechowalnictwie.
