Abstract In this article, the author juxtaposes writing and conversation about care for, with, and in spite of technology in Cambodia. The scene is medical care, and the actors are radiologists, engineers, cadres, and X-ray machines. A radiologist is forced to repair an X-ray machine for doctors of the revolution; the pressure and constraints are almost unreal, yet his skill in repair affirms his humanity and the specialized knowledge and creativity required for problem solving. An engineer teaches repair as he fixes an old X-ray machine. He finds words and necessary tools are missing in Phnom Penh, a familiar story of lack, yet repair is material practice that enables improvisation in spite of linguistic and epistemic challenges. A radiologist, the same one from before, in the twilight of his life, questions the dominance of technologies within medical care and the deskilling of doctors. Juxtaposing these stories bolsters attention for the mundane and creative work of keeping things going in a “broken world,” in line with the ways that care and repair are mobilized in STS. It also shows how the radical potential of “broken world thinking” is circumscribed when a broken world is the one from which people are struggling to distance themselves. What we are left with are multiple, overlapping, fraught stories of modernity in which need, choice, and pleasure of repair all have a place.

Background: St. Petersburg is a city of federal importance with a large number of primary patients, identified annually. Objective: analysis of the main indicators characterizing medical care for children with cancer in St. Petersburg and the Leningrad region. Methods: The operative reports for 2013-2017 of the Health Committee of the Government of St. Petersburg and the Health Committee of the Leningrad Region were analyzed. Results. In 2013-2017 in the Russian Federation, 18 090 primary patients were identified, 927 (5.1%) of them in the analyzed subjects: in St. Petersburg - 697 (75,2%), in the Leningrad Region - 230 (24,8%). For 5 years, the number of primary patients increased in St. Petersburg - by 36%, in the Leningrad Region - by 2,5%. The incidence increased in St. Petersburg by 18,1% (from 14,9 in 2013 to 17,6 in 2017 per 100 000 of children aged 0-17). The incidence in the Leningrad Region fell by 4.9% (from 14.4 in 2013 to 13.7 in 2017). Mortality in 2016-2017 in St. Petersburg increased by 50% (from 2 to 3), in the Leningrad Region - by 12,5% (from 2,4 to 2,7). The one-year mortality rate in St. Petersburg increased by 3,9% (from 2,5 to 6,4%). In the Leningrad Region, the one-year mortality rate decreased from 6,5% in 2016 to 0 in 2017. The number of pediatric oncological beds did not change in St. Petersburg (0,9 per 10,000 children aged 0-17 years) and the Leningrad Region (0). In St. Petersburg patients were not identified actively in 2016-2017; in the Leningrad Region their percentage decreased from 8,7 to 0. The number of oncologists increased in St. Petersburg from 0,09 to 0.12 (+33,3%), in the Leningrad Region - from 0 to 0,03. Conclusion: Morbidity in St. Petersburg and the Leningrad region is significantly different, which indicates obvious defects in statistical data. Patients were not identified during routine preventive examinations which indicate a low oncologic alertness of district pediatric physicians. Delivery of medical care for children with cancer and the statistical data accumulation procedures should be improved.

ZnOTe compounds were grown by DC magnetron cosputtering from pure Tellurium (Te) and Zinc (Zn) cathodes in O2/Ar atmosphere. The applied power on the Zn target was constant equal to 100 W, while the one applied on the Te target took two values, i.e., 5 W and 10 W. Thus, two sample series were obtained in which the variable parameter was the distance from the Te targets to the substrate. Sample compositions were determined by Rutherford Backscattering Spectroscopy (RBS) experiments. Structural analysis was done using X-Ray diffraction (XRD) spectrometry and the growth of the hexagonal w-ZnO phase was identified in the XRD spectra. RBS results showed high bulk homogeneity of the samples forming ZnOTe alloys, with variable Te molar fraction (MF) ranging from 0.48–0.6% and from 1.9–3.1% for the sample series obtained at 5 W and 10 W, respectively. The results reflect great differences between the two sample series, particularly from the structural and optical point of view. These experiments point to the possibility of Te doping ZnO with the permanence of intrinsic defects, as well as the possibility of the formation of other Te solid phases when its content increases. The results and appreciable variations in the band gap transitions were detected from Photoluminescence (PL) measurements.

Ureasil-Poly(ethylene oxide) (ureasil-PEO500) and ureasil-Poly(propylene oxide) (u-PPO400) films, unloaded and loaded with dexamethasone acetate (DMA), have been investigated by carrying out atomic force microscopy (AFM), ultrasonic force microscopy (UFM), contact-angle, and drug release experiments. In addition, X-ray diffraction, small angle X-ray scattering, and infrared spectroscopy have provided essential information to understand the films’ structural organization. Our results reveal that while in u-PEO500 DMA occupies sites near the ether oxygen and remains absent from the film surface, in u-PPO400 new crystalline phases are formed when DMA is loaded, which show up as ~30–100 nm in diameter rounded clusters aligned along a well-defined direction, presumably related to the one defined by the characteristic polymer ropes distinguished on the surface of the unloaded u-POP film; occasionally, larger needle-shaped DMA crystals are also observed. UFM reveals that in the unloaded u-PPO matrix the polymer ropes are made up of strands, which in turn consist of aligned ~180 nm in diameter stiffer rounded clusters possibly formed by siloxane-node aggregates; the new crystalline phases may grow in-between the strands when the drug is loaded. The results illustrate the potential of AFM-based procedures, in combination with additional physico-chemical techniques, to picture the nanostructural arrangements in polymer matrices intended for drug delivery.

SummaryThe importance and difficulties of determining the height of hard X-ray sources in the solar atmosphere, in order to distinguish source models, have been discussed by Brown and McClymont (1974) and also in this Symposium (Brown, 1975; Datlowe, 1975). Theoretical predictions of this height, h, range between and 105 km above the photosphere for different models (Brown and McClymont, 1974; McClymont and Brown, 1974). Equally diverse values have been inferred from observations of synchronous chromospheric EUV bursts (Kane and Donnelly, 1971) on the one hand and from apparently behind-the-limb events (e.g. Datlowe, 1975) on the other.

Abstract Cesium hydroxide, CsOH, was for the first time characterised on the basis of single-crystal data. The structure is isotypic to the one of the room-temperature modification of NaOH and can be derived from the NaCl structure type thus allowing the comparison of all alkali metal hydroxide structures. Raman spectroscopic investigations show the hydroxide anion to behave almost as a free ion as in the gas phase. The X-ray investigations indicate possible H atom positions.

Hyaluronan (HA), a polymeric glycosaminoglycan ubiquitously present in higher animals, is hydrolyzed by hyaluronidases (HAases). Here, we used bee HAase as a model enzyme to study the HA-HAase interaction. Located in close proximity to the active center, a bulky surface loop, which appears to obstruct one end of the substrate binding groove, was found to be functionally involved in HA turnover. To better understand kinetic changes in substrate interaction, binding of high molecular weight HA to catalytically inactive HAase was monitored by means of quartz crystal microbalance technology. Replacement of the delimiting loop by a tetrapeptide interconnection increased the affinity for HA up to 100-fold, with a KD below 1 nm being the highest affinity among HA-binding proteins surveyed so far. The experimental data of HA-HAase interaction were further validated showing best fit to the theoretically proposed sequential two-site model. Besides the one, which had been shown previously in course of x-ray structure determination, a previously unrecognized binding site works in conjunction with an unbinding loop that facilitates liberation of hydrolyzed HA.

Abstract It is important that clinical research with children is encouraged so that they are not exposed to the dangers of extrapolation from adult treatments. Clinical trials with investigational medicinal products (imps) are an important part of improving medical care for children. Both the 2001 Clinical Trials Directive and the 2014 Regulation recognise the need for such research, including the need for non-therapeutic trials with imps. However, it is also recognised that a balance must be struck between permitting tailored medical care for children as a group on the one hand, and protecting individual trial participants from harm on the other. A central issue in striking this balance relates to defining the threshold of risk which should be permitted in such research. This article provides a critical analysis of the current European law in relation to the definition of acceptable risk for non-therapeutic clinical trials with imps and makes recommendations for reform, drawing on law from the Council of Europe, as well as law from the us.

In this paper, a novel and highly efficient hydroxyapatite (HA) carrier for cultivating hydrocarbon degradation bacteria (HDB) is introduced. The HA particles synthesized through a sol-gel method and different heat treatments were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and BET method. The microbial amount and activities of HDB cultivated on HA carriers were quantitatively investigated in order to assess their enriching capabilities. The results showed that HA synthesized at 550°C and the one without calcination could enrich HDB 3 and 2 magnitude orders more than the activated carbon, respectively. Mechanisms of bacterial enrichment on HA and activated carbon were also studied, and it is believed that the high bioactivity and the surface morphology of HA were responsible for the efficient reproduction of HDB. It is concluded that HA is a potential candidate to replace the conventionally used activated carbon as a novel carrier applied in the filed of bioremediation for oil contaminated soil.

The Revolution

"The fundamental transformations through the Romanian state passed since the Revolution of December 1989, have also put their mark on the legal system. For this reason, there have been major changes in the content of administrative law. However, the regulation of the territorial-administrative subdivisions survived the change of political regime, due to Law 2/1968. Moreover, regulations on administrative-territorial subdivisions are also found in Law 215/2001 and in the 1991 Constitution, revised in 2003. This has led to problems of interpretation. Thus, on the one hand, we need to identify who has the right to constitute administrative-territorial subdivisions, and on the other hand, it must be seen whether the answer to the first question, leads to a possible interpretation that would be unconstitutional. At the same time, administrative-territorial subdivisions have created problems of interpretation regarding their legal capacity. Through this article, we have proposed to look at the issues mentioned above."
