Decomposition of individual components of bio-organic waste: volatile organic compounds and the impact on health and psycho-emotional state

The study considers the impact on the person’s health and psycho-emotional state of unpleasant odors arising from the storage and accumulation of bioorganic waste, including food waste (meat, poultry, fruits and vegetables) and bird droppings. The survey data of poultry and livestock farms’ employees in Serbia are given. The impact of unpleasant odors on the Waste sorting complex (Moscow region) employees’ vital signs is assessed. The impact of high-intensity odor groups for individual components of food waste (pork meat, poultry meat, vegetables and fruits) and bird droppings was studied by interviewing volunteers and measuring their vital signs

Приведены данные опроса работников птицеводческих и животноводческих ферм Сербии. Оценено влияние неприятных запахов на показатели жизнедеятельности работников Комплекса по сортировке отходов (КПО) (Московская область). Влияние групп запахов высокой интенсивности на отдельные компоненты пищевых отходов (мяса свинины, мяса птицы, овощей и фруктов) и птичьего помета изучали путем опроса добровольцев и измерения их показателей жизнедеятельности

Resonant X-ray emission spectroscopy reveals d–d ligand-field states involved in the self-assembly of a square-planar platinum complex

Resonant X-ray Emission Spectroscopy (RXES) is used to characterize the ligand field states of the prototypic self-assembled square-planar complex, [Pt(tpy)Cl]Cl (tpy=2,2′:6′,2′′-terpyridine), and determine the effect of weak metal-metal and π-π interactions on their energy. © 2012 the Owner Societies

N-atom Production at High Electric Fields: E-FISH and TALIF Experiments for Understanding Fast Ionization Wave Kinetics

International audienceThis work forms part of a larger effort to develop a suite of diagnostics for making measurements in non-equilibrium, nanosecond pulse discharges, so as to facilitate an improved understanding of the plasma kinetics. Electric field induced second harmonic (E-FISH) generation, is used to probe the electric field in a fast ionization wave, nanosecond pulse discharge in pure N2 at a pressure of 20 mbar. The field evolution during the fast ionization wave development is clearly captured in the form of three distinct phases. An initial field overshoot ahead of the front to about 10.5 kV/cm (or about 2 kTd), followed by a field drop as the wave traverses the measurement location, and finally a subsequent rise as a quasi-steady state regime is established. TALIF measurements of N-atom density are also performed with a view to understanding the impact of the reduced electric field on the consequent atomic species production. These measurements are limited to the post-discharge phase, mainly due to the poor signal to raise ratio associated with the lower atomic densities and strong fluorescence-overlapping plasma emission. A relatively low peak N-atom density of about 5.5 x 10 12 cm-3 is obtained, in line with the low specific deposited energy of this discharge (0.01 eV/molecule). Finally, attempts to model this plasma show that the results of simulations are strongly influenced by the radial non-uniformity of the discharge
