The exchange of radiophosphonis between water on the one hand and Artemia, Gammarus, and microorganisms on the other was observed. Results are expressed as turnover time, which is related to the rate at which phosphorus moves back and forth, being defined as the time required for as much material as is present to enter or leave a phase of the system. Tt for Arlemia is 14 hours; for Gammarus 43 hours; the equilibrium between organic and inorganic phosphorus in the presence of microorganisms has a Tt of 19 hours. In Gammarus there is a lag period of a few hours before they reach a maximal uptake rate. Gammarus, treated with terramycin to kill bacteria, do not remove appreciable quantities of radiophosphorus from water. Evidently they must acquire their phosphorus from particulate matter, such as bacteria.

AbstractThis report presents the results of a study regarding the transfer of maleic hydrazide (MH) into mainstream cigarette smoke. Cigarettes with different levels of MH were used in this study. This included cigarettes with MH preexistent in the tobacco due to the agronomical practice, and with spiked MH. Because the MH can be present in tobacco as bound and free forms, both levels of MH were measured in the tobacco section. The cigarette designs covered a range of possibilities, including Plain, Filter King Size (KS), Lights 100’s, Ultra Lights, etc. The results showed that the amount of MH in smoke, on the one hand, is a function of the total particulate matter (TPM) of the cigarette, and higher TPM levels lead to more MH in smoke. On the other hand, the transferred level of MH depends on the total amount of MH (both bound and free) in the tobacco. The relative % transfer is higher for lower MH levels than for higher MH levels in tobacco. When normalized by TPM, the transfer as an average is about 0.24% per mg of TPM from the amount of MH in 1 g of tobacco, and as high as 0.46% per mg of TPM from the amount of MH in 1 g tobacco for a nonfilter low MH level cigarette. The resulting MH transfer for a nonfilter cigarette with low tobacco MH is therefore about 8.3% from the total MH in the cigarette. For filter full flavor (FF) cigarettes with high tobacco levels of MH, the transfer is about 5.8%. This relative transfer rate appears to be lower from higher MH levels in tobacco.

SummaryInvestigations of the clotting mechanism were carried out by lysis time determinations when plasminogen was activated by streptokinase and the following results were obtained:1. The recalcification time during the period of activation showed an initial decrease of the clotting time, followed by a prolongation.The thrombin time method showed only a prolongation up to the moment when inhibition of coagulation occurred.2. The clotting factors II, V, VII, VIII and IX remained unaffected in this system.3. The clotting activity, as well as the time required for the inhibition of coagulation, were dependent on the streptokinase concentration on the one hand, and on the fibrinogen concentration on the other.4. An antithrombin-like inhibitor could be excluded as the cause of incoagulability.5. In our system, inhibition of coagulation was caused by fibrinogenolysis, by which fibrinogen was altered to a biologically inactive globulin. The latter could still be demonstrated in large amounts by means of certain protein estimations. But the proteolytic activity is assumed to be not strong enough to destroy the other clotting factors as well.This system is, therefore, especially useful for studying the isolated “anti-fibrinogenic“ effect of plasmin.

The conditions established to regulate the admission of patients into lunatic asylums have given rise, in every country, to a great deal of discussion. On the one hand, many unacquainted with medicine are inclined to dread the abuse of the power to confine individuals not really insane under the pretext of insanity, and with more or less criminal intent; therefore these persons contend that admissions to asylums should be preceded by intricate formalities and repeated inquiries, with the interference of some public authority, such as a commission of either judicial or administrative officers. On the other hand, physicians advocate the necessity of prompt recourse to an asylum, not only for the patient's own benefit, but for his family's welfare; they demonstrate that a man labouring under acute insanity cannot be left to himself during the time required to set in motion the working of such complicated machinery as that proposed to be brought into action prior to his admission into a hospital; they further reject all interference of the public authorities to this end, as hurtful to private family feeling and the maintenance of professional secrecy, demanding, likewise, the greatest facilities for easy admission, guaranteed, nevertheless, by any number of subsequent examinations, or other means of inquiry into the case; and, finally, they hold that such supposed illegal confinements do not exist, since it has not been proved that any one really of sound mind has ever been shut up in any asylum, and that, therefore, the liberty of the subject is in no danger whatever. So in this respect we may rest confident, seeing that the past gives us full assurance for the future. Such is, upon the whole, the main point of dispute in every discussion on the subject, which happens to spring up again and again in different countries.

<p>Air Quality in Berlin is a particular problem during winter episodes. During this episodes, local emissions are only one factor contributing to the high concentrations. The other factors are the lowered height of the planetary boundary layer and the advection of pollutants, some of which are produced in Eastern Europe. To trace the share of total pollution in Berlin for 2016-18 back to its origins, the Chemistry Transport Model (CTM) LOTOS-EUROS v2.1 (LOng Term Ozone Simulation EURopean Operational Smog, invented by TNO, Netherlands) is used, which also provides a labelling approach. Some specifications were made for the emission datasets used to drive the model, including emission dependencies on temperature (e.g. cold engine starts and heating degree-days for households).</p><p>The model results are evaluated using the German AirBase monitoring sites. An incremental approach (Lenschow et al., 2001) is used for the evaluation and estimation of the urban share of Berlin. The focus is on Particulate Matter (PM): PM10, PM2.5, and the coarse-mode fraction (PM10-PM2.5). Due to the seasonal variability of PM and its composition, seasonal differentiation is investigated. The labelling approach provided in LOTOS-EUROS allows to distinguish between the sources relevant for Berlin’s PM pollution, with the focus of this work on local contributions such as households and traffic on the one hand and regional contributions from Berlin itself and Germany’s Eastern European neighbors (Poland and the Czech Republic) on the other hand.</p><p>This study is in relation to the “Berliner Luftreinhalteplan” (Berlin Clean Air Plan).</p>

The first question to be answered, in seeking coordinate systems for geodynamics, is: what is geodynamics? The answer is, of course, that geodynamics is that part of geophysics which is concerned with movements of the Earth, as opposed to geostatics which is the physics of the stationary Earth. But as far as we know, there is no stationary Earth – epur sic monere. So geodynamics is actually coextensive with geophysics, and coordinate systems suitable for the one should be suitable for the other. At the present time, there are not many coordinate systems, if any, that can be identified with a static Earth. Certainly the only coordinate of aeronomic (atmospheric) interest is the height, and this is usually either as geodynamic height or as pressure. In oceanology, the most important coordinate is depth, and this, like heights in the atmosphere, is expressed as metric depth from mean sea level, as geodynamic depth, or as pressure. Only for the earth do we find “static” systems in use, ana even here there is real question as to whether the systems are dynamic or static. So it would seem that our answer to the question, of what kind, of coordinate systems are we seeking, must be that we are looking for the same systems as are used in geophysics, and these systems are dynamic in nature already – that is, their definition involvestime.

Abstract. Two experiments examined the influence of stories on recipients’ self-perceptions. Extending prior theory and research, our focus was on assimilation effects (i.e., changes in self-perception in line with a protagonist’s traits) as well as on contrast effects (i.e., changes in self-perception in contrast to a protagonist’s traits). In Experiment 1 ( N = 113), implicit and explicit conscientiousness were assessed after participants read a story about either a diligent or a negligent student. Moderation analyses showed that highly transported participants and participants with lower counterarguing scores assimilate the depicted traits of a story protagonist, as indicated by explicit, self-reported conscientiousness ratings. Participants, who were more critical toward a story (i.e., higher counterarguing) and with a lower degree of transportation, showed contrast effects. In Experiment 2 ( N = 103), we manipulated transportation and counterarguing, but we could not identify an effect on participants’ self-ascribed level of conscientiousness. A mini meta-analysis across both experiments revealed significant positive overall associations between transportation and counterarguing on the one hand and story-consistent self-reported conscientiousness on the other hand.

SummaryThe prognosis of patients with acute myeloid leukaemia (AML) has improved considerably by introduction of aggressive consolidation chemotherapy and haematopoietic stem cell transplantation (SCT). Nevertheless, only 20-30% of patients with AML achieve long-term diseasefree survival after SCT. The most common cause of treatment failure is relapse. Additionally, mortality rates are significantly increased by therapy-related causes such as toxicity of chemotherapy and complications of SCT. Including radioimmunotherapies in the treatment of AML and myelodyplastic syndrome (MDS) allows for the achievement of a pronounced antileukaemic effect for the reduction of relapse rates on the one hand. On the other hand, no increase of acute toxicity and later complications should be induced. These effects are important for the primary reduction of tumour cells as well as for the myeloablative conditioning before SCT.This paper provides a systematic and critical review of the currently used radionuclides and immunoconjugates for the treatment of AML and MDS and summarizes the literature on primary tumour cell reductive radioimmunotherapies on the one hand and conditioning radioimmunotherapies before SCT on the other hand.

In recent years, political and social conditions have changed dramatically. Many analyses help to capture these dynamics. However, they produce political pessimism: on the one hand there is the image of regression and on the other, a direct link is made between socio-economic decline and the rise of the far-right. To counter these aspects, this article argues that current political events are to be understood less as ‘regression’ but rather as a moment of movement and the return of deep political struggles. Referring to Jacques Ranciere’s political thought, the current conditions can be captured as the ‘end of post-democracy’. This approach changes the perspective on current social dynamics in a productive way. It allows for an emphasis on movement and the recognition of the windows of opportunity for emancipatory struggles.

Political ideological pluralism, religious diversity are characteristic features of modern Ukrainian society. On the one hand, multiculturalism, socio-political, religious differentiation of the latter appear as important characteristics of its democracy, as a practical expression of freedom, on the other - as a factor that led to the deconsocialization of society, gave rise to "nodal points" of tension, confrontational processes, in particular, in political and religious spheres.

Two aspects of Schumpeter' legacy are analyzed in the article. On the one hand, he can be viewed as the custodian of the neoclassical harvest supplementing to its stock of inherited knowledge. On the other hand, the innovative character of his works is emphasized that allows to consider him a proponent of hetherodoxy. It is stressed that Schumpeter's revolutionary challenge can lead to radical changes in modern economics.
