Chlorinated and methylated dibenzothiophenes: Preparation of the model compounds and their analysis from some environmental samples
1990
Abstract Polychlorinated and polymethylated dibenzothiophenes if occuring in the environment can cause environmental hazards and problems like chlorinated dibenzodioxins and dibenzofurans. Some chlorinated and methylated dibenzothiophenes have been synthesized to serve as model compounds in environmental and toxicological analysis. The synthesis mixtures and some environmental samples have been analyzed by high resolution GC/low resolution MS. This investigation showed that the concentrations of these compounds in environmental samples were below ppb level but it did not exclude the occurence of these compounds in our environment. More investigation is needed.
Phytoscreening as an efficient tool to delineate chlorinated solvent sources at a chlor-alkali facility
2017
Chlorinated ethenes (CE) are among the most common volatile organic compounds (VOC) that contaminate groundwater, currently representing a major source of pollution worldwide. Phytoscreening has been developed and employed through different applications at numerous sites, where it was generally useful for detection of subsurface chlorinated solvents. We aimed at delineating subsurface CE contamination at a chlor-alkali facility using tree core data that we compared with soil data. For this investigation a total of 170 trees from experimental zones was sampled and analyzed for perchloroethene (PCE) and trichloroethene (TCE) concentrations, measured by solid phase microextraction gas chromato…
Reversible dehydration polymerization of terephthalate bridged [{Cu2(2,2′-bpy)2(tp)(H2O)3(NO3)}·H2O·NO3]2
2006
The title compound is the first example of a molecular magnet sponge, which exhibits a carboxylate-assisted unique reversible dehydrative polymerization–rehydrative monomerization phenomenon.
Combining inulin multifunctional polycation and magnetic nanoparticles: Redox-responsive siRNA-loaded systems for magnetofection
2019
Superparamagnetic Iron Oxide Nanoparticles (SPIONs) are recognized as one of the most promising agents for theranostic applications. Among methods designed for siRNA delivery, magnetofection, that is, nucleic acid cell uptake under the influence of a magnetic field acting on magnetic nucleic acid vectors, is emerging as a unique approach to combining advantages such as strong improvement of the kinetics of the delivery process and the possibility of localizing nucleic acid delivery to an area where the magnetic field is applied. This paper reports on the preparation of siRNA loaded magnetoplexes&mdash
Innovating European Long-Term Care Policies through the Socio-Economic Support of Families: A Lesson from Practices
2022
LTC and socio-economic deprivation of families are two relevant issues in international debate. The economic or time investment made by families in caregiving has an impact on the socio-economic status of family members in terms of economic means and social inclusion. This study analyzes the practices that are supported by home LTC, examining their characteristics, identifying their strengths, weaknesses, drivers, and barriers, as well as identifying social innovation aspects. The study provides a qualitative interpretative comparison of 22 practices from eight countries, representing the four LTC care models existing in Europe. Cross-studies aid in the development of sustainable policies. …
Impact of landscape on spatial genetic structure and diversity ofCoenagrion mercuriale(Zygoptera:Coenagrionidae) in northern France
2015
AbstractLoss and fragmentation of habitat is a current main cause of biodiversity loss in freshwater habitats. Odonates (dragonflies and damselflies) depend on these habitats to complete their development. Fragmentation may be a particular threat for odonates because it generates a network of small habitat patches within which populations could suffer from isolation and loss of genetic diversity. The southern damselfly Coenagrion mercuriale is categorized on the IUCN red list as Near Threatened, largely because of population fragmentation and demographic declines associated with changes in land use. Small populations at the margin of this species’ range are of particular concern because the…
Spin crossover properties of the [Fe(PM-BiA)2(NCS)2] complex - phases I and II
2003
International audience; In the present review, we reexamine the photomagnetic properties of the [Fe(PM-BiA)2(NCS)2], cis-bis(thiocyanato)-bis[(N-2'-pyridylmethylene)-4-(aminobiphenyl)]iron(II), compound which exhibits, depending on the synthetic method, an exceptionally abrupt spin transition (phase I) with a very narrow hysteresis (T1/2O = 168 K and T1/2N = 173 K) or a gradual spin conversion (phase II) occurring at 190 K. In both cases, light irradiation in the tail of the 1MLCT-LS absorption band, at 830 nm, results in the population of the high-spin state according to the light-induced excited spin-state trapping (LIESST) effect. The capacity of a compound to retain the light-induced HS…
Weyers acrodental dysostosis in a family.
1984
A four generation family with postaxial polydactyly of hands and feet and dental anomalies is reported. Lower and upper incisors were abnormal in shape and number. Additional findings were prominent ear anthelices, hypoplastic and dysplastic nails and mild shortness of stature. Inheritance was dominant with variable expression. It is proposed that the family presents the syndrome of acrofacial dysostosis described by Weyers in 1952. To differentiate it from other acrofacial dysostoses, we suggest naming the condition acrodental dysostosis.
Analysis of factors determining thermal changes at osteotomy site in dental implant placement - An in-vitro study
2021
Background Heat generation during osteotomy site preparation is a crucial factor that determines the success of dental implant placement. Among the factors that affect the heat generation, drilling speed, hand pressure and coolant temperature are independent variables. However, a relation between these three parameters and their optimal values required for the maximum outcome has not been studied so far. This study aims at finding out a relation between these factors in order to derive the optimum balance required, using an in vitro study. Material and methods This in vitro experiment was performed on bovine femur. A total of 72 drillings were undertaken with the aid of a physiodispenser mo…
Laundry detergent compatibility of the alkaline protease from Bacillus cereus.
2004
The endogenous protease activity in various commercially available laundry detergents of international companies was studied. The maximum protease activity was found at 50 degrees C in pH range 10.5-11.0 in all the tested laundry detergents. The endogenous protease activity in the tested detergents retained up to 70% on incubation at 40 degrees C for 1 h, whereas less than 30% activity was only found on incubation at 50 degrees C for 1 h. The alkaline protease from an alkalophilic strain of Bacillus cereus was studied for its compatibility in commercial detergents. The cell free fermented broth from shake flask culture of the organism showed maximum activity at pH 10.5 and 50 degrees C. The…
