Retrospective determination of U and Pu isotopes and atom ratios in lung samples from Vienna, Austria.

Uranium and plutonium isotope concentrations as well as U/U and Pu/Pu atom ratios were measured by AMS in human lung samples from the early 1960s. The U concentrations as well as the U/U atom ratios show a maximum in 1964, Pu and Pu concentrations are increasing continually from 1962 to 1965. U/U atom ratios are lower by two orders of magnitude compared to corresponding aerosol data from Vienna, probably due to older U deposited in the lungs, enhanced U concentrations in the city air, and activity partition within different particle sizes.

Extreme weather layer method for implementation of nature-based solutions for climate adaptation: Case study Słupsk.

One of the most severe climate risks that is expected to affect all regions is related to stormwater. Climate models, constructed based on long-term trends, show that extreme weather events such as storms, cloudbursts and a large rise in sea level will be significant in the coming decades. Moreover, even the frequency and intensity of "normal" rainfall events, such as microbursts, are expected to be remarkably higher than today in some regions.

Tracking Fluorescent Dye Dispersion from an Unmanned Aerial Vehicle.

Commercial unmanned aerial vehicles continue to gain popularity and their use for collecting image data and recording new phenomena is becoming more frequent. This study presents an effective method for measuring the concentration of fluorescent dyes (fluorescein and Rhodamine WT) for the purpose of providing a mathematical dispersion model. Image data obtained using a typical visible-light camera was used to measure the concentration of the dye floating on water.

Towards a multi-basin SWAT model for the migration of nutrients and pesticides to Puck Bay (Southern Baltic Sea).

Background: This paper analyzes the impact of changes in fertilization on crop yields and the runoff of nutrients from a small agricultural catchment (176 km) to a shallow bay, using the SWAT model. Puck Bay is part of the Gulf of Gdansk and belongs to the Baltic Sea. The whole area of Puck Bay (364 km) is protected (Natura 2000) yet despite this it suffers from eutrophication problems due to the relatively minimal depth and difficult water exchange.

Nutrient loss from three small-size watersheds in the southern Baltic Sea in relation to agricultural practices and policy.

Agriculture is the major contributor of waterborne nutrient fluxes into the Baltic Sea, one of the world's most eutrophication-sensitive areas. Poland, as a large, densely populated state ohf the Baltic Region, with dominating agricultural land use, largely contributes to riverborne loads of N and P. The aim of our study was to examine the input of nutrients from three small first-order agricultural watersheds (Bladzikowski Stream, Gizdepka river and Mrzezino canal) in the Pomerania region, into the Bay of Puck, inner part of the Gulf of Gdansk.

Reproduction of the Atlantic Forest endemic star-throated antwren, Rhopias gularis (Aves: Thamnophilidae).

The Thamnophilidae are one of the most speciose Neotropical bird families, yet aspects of their natural history remain poorly documented. Here we provide information on breeding phenology, the length of incubation and nestling periods, parental care, and nesting success of the Star-throated Antwren, Rhopias gularis, an Atlantic Forest endemic. The data are discussed in light of life history theories.

Combining computational fluid dynamics with a biokinetic model for predicting ammonia and phosphate behavior in aeration tanks.

The aim of this study was to use computational fluid dynamics for predicting the behavior of reactive pollutants (ammonia and phosphate) in the aerobic zone of the bioreactor located at the Wschod wastewater treatment plant in Gdansk, Poland. The one-dimensional advection-dispersion equation was combined with simple biokinetic models incorporating the Monod-type expressions as source terms for the two pollutants. The problem was solved numerically by a multi-step splitting technique algorithm.

Effects of different hydraulic models on predicting longitudinal profiles of reactive pollutants in activated sludge reactors.

This paper presents effects of dispersion on predicting longitudinal ammonia concentration profiles in activated sludge bioreactor located at "Wschod" WWTP in Gdansk. The aim of this study was to use the one-dimensional advection-dispersion Equation (ADE) to simulate the flow conditions (based on the inert tracer concentrations in selected points) and longitudinal profile of reactive pollutant (based on the ammonia concentration profiles in selected points). The simulation results were compared with the predictions obtained using a traditional "tanks-in-series" (TIS) approach, commonly used in designing biological reactors.

IgA nephropathy associated with psoriasis vulgaris: a contribution to the entity of 'psoriatic nephropathy'.

Background: It is generally accepted that there is no higher prevalence of renal disease in psoriatic patients, except in the case of secondary renal amyloidosis in psoriatic arthropathy. Contrary to this, however, some authors suggest that kidney diseases in psoriasis vulgaris may be more common and they presume the existence of 'psoriatic nephropathy'.

Method: We report a case of IgA nephropathy in a patient with psoriasis vulgaris as a contribution to the ongoing discussion concerning this entity of 'psoriatic nephropathy'.

Temperature modeling in activated sludge systems: a case study.

A model of temperature dynamics was developed as part of a general model of activated-sludge reactors. Transport of heat was described by the one-dimensional, advection-dispersion equation, with a source term based on a theoretical heat balance over the reactor. The model was compared to several reference models, including a tanks-in-series model and the dispersion model with heat components neglecting biochemical-energy inputs and other activated-sludge, heat-balance terms.

[Microbiological diagnosis of mycobacterioses caused by Mycobacterium haemophilum].

Introduction: According to foreign literature Mycobacterium haemophilum causes diseases of the skin, subcutis and lymph nodes in immunocompetent individuals, while in AIDS patients and in subjects after kidney transplantations it is responsible for osteomyelitis and disseminated infections.

Material And Methods: The authors tested the possibility of using a BioFM medium with the X-factor for the detection of Mycobacterium haemophilum in clinical samples and Middlebrook's 7H9 medium with ADC and the X-factor to establish the sensitivity of strains to antimicrobials using the MIC method.

Conclusions: Given the favourable results of preliminary tests the use of the BioFM medium was included among the routine methods applied at the department.

[Surgical treatment of injuries of the bile ducts].

The bile ducts were injured during cholecystectomy in 143 of 155 patients treated at the clinic. In most cases (78) the iatrogenic injuries occurred under conditions of a severe inflammatory and cicatricial process in the zone of the cystic neck and hepaticocholedochus. Mortality in correction of a fresh injury of the duct by the traditional methods was 11.

[Cicatricial strictures of anastomosis of the hepatic duct and common bile duct].

The authors have observed 34 cases of scarry strictures of bilio-digestive anastomoses requiring repeated surgical correction. The causes of such complications, methods of clinical and special diagnostic are discussed. The technique of reoperations for such complications is described along with their results and recommendations for prevention of scarry strictures of anastomoses of the common hepatic duct.

[Pancreatitis in obstruction of Vater's ampulla].

Clinical observations of 478 patients operated for pancreatitis resulting from different obturating lesions of the Vater papilla (stones, cicatricial stenosis, polyps etc.) are analyzed. The questions of diagnosis, preoperative preparation, medical methods, technique of the operation and postoperative management are discussed.
