Résumé :

When and where might ethnic party outbidding occur? This article examines potential outbidding dynamics via a study of local elections in Romania, where the dominant Hungarian UDMR/RMDSz (Democratic Alliance of Hungarians in Romania) was recently challenged by a rival party, the MPP (Hungarian Citizens’ Party). A comparison of election results is made across cities and counties that differ according to demographic characteristics. Two primary findings emerge. First, Hungarian unity in the form of the RMDSz remained strong except under enclave conditions — where the ethnic minority is the local

In this study urethane dimethacrylate (UDMA) based dental resin materials were synthesized. Urethane methacrylate oligomers (UDMO) were synthesized via a radical chain growth polymerization mechanism using polyethylene glycol (PEG) in order to improve the mechanical properties, without adding a solvent in the reaction medium. The structure of the new monomer and oligomer were confirmed by FT-IR and 1H-NMR spectra. The results of FT-IR analysis indicated that the addition of PEG as plasticizer in the urethane methacrylate dental material in the adequate molar ratio (isophorone diisocyanate : HE

Unsymmetrical dimethylhydrazine (UDMH) is a kind of cheap propellant for rocket luanching. But it is harmful to environment and human body. At present, the majority of UDMH eliminating agents are unsafe and inconvenient for use because of strong oxidizing property. The eliminating effects of vitamin B6, vitamin C and glacial acetic acid on UDMH are studied. 1mg vitamin B6 , 1mg vitamin C and 1mg glacial acetic acid is added into 10.00ml UDMH solution (1μg/ml) respectively, UDMH content is determined respectively in 30 minutes and 60 minutes through amino sodium ferrocyanide (TPF) spectrophotom

Résumé :

Urethane dimethacrylate (UDMA) is a dimethacrylate-based resin monomer that can react with other related monomers and inorganic particles, causing hydrophobic polymerization through cross-linking upon light activation. UDMA polymers are commonly used for the reconstruction and reinforcement of teeth and bones. UDMA can become unbound and be released from light-cured polymer resins. Thus far, no evidence exists on the toxic effects of UDMA and its related working mechanisms for macrophages. Therefore, in the present study, we investigated the cytotoxicity, mode of cell death, DNA damage, caspas

Résumé :

The present article presents some theoretical considerations about the implicationsdue the change of the oxidizer in a bipropellant propulsion system. Preliminaryanalysis conducted on the NTO/UDMH 400 N engine of a roll control system showsthat this engine could be capable of operation with HTP90 without significantmodification in the design. The new propellant combination is less toxic, can behandled more easily, has a wider operational temperature range, and yields a moreamenable thermal environment from the combustion down to the exhaustion.

Résumé :

This work on organic dental composites was undertaken to determine the role of residual reactive methacrylate functions at the end of the photopolymerization cycle, and to investigate the fate of the residual monomers and oligomers in organic (ethanol) and aqueous (water and artificial saliva) media. The results show that all the methacrylate monomers present in dentine migrate into ethanol (about 1% (w/w)). In aqueous media on the other hand, only the most hydrophilic monomer (UDMA) migrates (0.05% (w/w)) into water and 0.03% into artificial saliva (pH = 9). This desorption in the three media

Résumé :

This essay considers the Universal Declaration of Human Rights (UDHR) at a time at which humans are dramatically changing the planet, prompting scientists to suggest that we are living in a new geological epoch: “the Anthropocene.” The Anthropocene, even if an essentially contested concept, prompts reconsideration of our interhuman socioeconomic relations and our understanding of the human-nature interface, both of which come with significant challenges. This essay suggests that the UDHR offers the space for engaging with these challenges, if we adopt an Anthropocene-relevant reading of its pr

Résumé :

AbstarctThe Uniform Data System for Medical Rehabilitation (UDSmr) provides a method for uniform assessment of the severity of patient disability and the outcomes of medical rehabilitative care. The effectiveness and efficiency of medical rehabilitation services may be analyzed using the Functional Independence Measure (FIM), the functional assessment component of the UDS, and other data. Program evaluation models based on the UDSMR and the FIM are useful for measuring resource cost of disability.

Résumé :

Abstract A new method for determining 1,1-dimethylhydrazine (UDMH) in peaches and apples is presented. The method consists of extraction with L-ascorbic acid, derivatization with 2-nitrobenzaldehyde to the corresponding hydrazone, and cleanup on an alumina column. The hydrazone derivative is determined by gas chromatography using an electron-capture detector. Recoveries were determined from 10 to 100 ppb. Stability of the UDMH residues on frozen peaches was investigated, and results indicate that the residues degrade even while frozen.

The relations between moral reasoning and political attitudes were examined in a representative sample of 2520 Dutch adolescents and young adults. This study was repeated for a second, select sample, 210 Dutch university students. In the latter study both moral reasoning and political attitudes were related to the evaluation of the 30 articles of the Universal Declaration of Human Rights (UDHR). Moral reasoning was measured using the N2 index of the Defining Issues Test (Rest, 1979a). Political attitudes were measured using 10 Likert-type multiitem scales, representing both the cultural and th

Résumé :

The use of highly toxic rocket fuel based on 1,1-dimethylhydrazine (UDMH) in many types of carrier rockets poses a threat to environment and human health associated with an ingress of UDMH into wastewater and natural reservoirs and its transformation with the formation of numerous toxic nitrogen-containing products. Their GC-MS quantification in aqueous samples requires matrix change and is challenging due to high polarity of analytes. To overcome this problem, accelerated water sample preparation (AWASP) based on the complete removal of water with anhydrous sodium sulfate and transferring ana

Résumé :

Most of the dental materials available on the market are still based on traditional monomers such as bisphenol A-glycidyl methacrylate (Bis-GMA), urethane dimethacrylate (UDMA), triethyleneglycol dimethacrylate (TEGDMA), and ethoxylated bisphenol-A dimethacrylate (Bis-EMA). The interactions that arise in the monomer mixture and the characteristics of the resulting polymer network are the most important factors, which define the final properties of dental materials. The use of three different monomers in proper proportions may create a strong polymer matrix. In this paper, fourteen resin materi
