Актуальные вопросы диагностики йерсиниоза в Республике Молдова
Centrul Naţional Ştiinţifico-Practic de Medicină Preventivă, Chişinău, Conferinţa Ştiinţifico-Practică „Medicina modernă, actualităţi şi perspective”, consacrată aniversării de 40 de ani ai Spitalului Clinic al Ministerului Sănătăţii, 27-28 mai, 2010, Chişinău, Republica MoldovaIn this work we present the results of 8784 examined patients (4410 by microbiological and 4374 by serological method), 5348 samples (intestine
and other internal organs) of more than 35 thousand small mammals, 247 samples of fish, 298 vegetable and fruit washes, 790 ambient samples
washes, 328 animals from the Chisinau zoo and 253 of other substrates to identify yersiniosis. It was established that in Moldova yersiniosis is
a local natural infection with all features of epizootic process in small mammals and requires active epizootic and epidemiological surveillance,
it has a wide spread in the human population, attacks all age groups and manifests in different syndromes of infectious and somatic diseases,
which lead to essential errors in the preliminary diagnosis of the disease.Были обследованы на выявление йерсиниоза 8784 пациентов (4410 микробиологическим и 4374 серологическим методом), 5348
образцов (кишечник и другие внутренние органы) более 35 тысяч мелких млекопитающих, 247 проб воды, 298 промывок овощей и
фруктов, 790 промывок образцов окружающей среды, 328 животных зоопарка Кишинева, 253 других субстратов. Было установлено,
что в Молдове йерсиниоз является инфекцией с природным очагом, со всеми характеристиками эпизоотического процесса у мелких
млекопитающих и требует активного эпизоотического эпидемиологического надзора. Йерсиниоз часто встречается у людей, поражает
все возрастные группы и проявляется различными синдромами инфекционных и соматических заболеваний, что приводит к
существенным отклонениям от истинного диагноза
Clogging vs. fouling in immersed membrane bioreactors
Whilst the fouling of MBR membrane surfaces has been very extensively explored by the academic community, there is an increasingly widespread recognition by practitioners of the issue of clogging of membrane channels with sludge solids, sometimes termed “sludging”. The study undertaken has quantified this phenomenon using a bespoke test cell allowing a flat sheet membrane channel to be viewed directly during operation and the accumulated solids determined by digital image processing. Sludging behaviour has then been correlated both with the sludge properties, from sludge samples taken from both an industrial and municipal MBR, and the permeability decline rate data.
The work has revealed the expected trends in fouling propensity, as quantified by the exponent n of the Δp/Δt = m.exp(nJ) correlation from classical flux-step tests. With zero membrane aeration the industrial samples exhibited sludging, the filling of the complete thickness of the membrane channel with sludge solids, whereas for municipal sludge the solids formed a cake layer which did not fill the channel. In the absence of sludging the permeability decline followed the expected pattern of increasing at the elevated soluble COD and capillary suction time values of the industrial sludge, compared with municipal sludge at the same solids concentration range (8–12 g.L−1). However, there was no evident correlation between fouling (permeability decline without sludging) and sludging: incipient sludging did not appear to influence permeability, though can be assumed to negatively impact on long-term operation, or relate to the sCOD concentration. Sludging instead appeared to depend on the sludge physical properties, and primarily the viscosity: sludge samples at high viscosities were found to exhibit a different air-scour pattern to that at normal MLSS concentrations.
Outcomes suggest that sludging is caused by rheological conditions promoting bubble coalescence and bubble stream constriction, reducing the exposure of the membrane surface to scouring air
TOPOGRAPHIC SURVEYS CARRIED FOR DRAWING GENERAL URBAN PLAN OF A VILLAGE FOR AGROTOURISTIC ARRANGEMENT
The paper aims at presenting a methodology and surveying equipment and technical documentation needed for the general urban plan, indispensable for agrotouristic arrangement works of a settlement. The investigations undertaken have shown that for preparing fast, accurate and detailed urban plan for the studied locality was necessary use of modern surveying technology, such as GPS technology, completed with the total station for surveying the details. It was also found that only use of such a method could produce a unitary and accurate urban plan with high efficiency, compliant with all requirements and technical standards imposed by law, for such work of great importance and complexity.Having the plan and technical data gathered from the field can be achieved in the best conditions a design and implementation at the highest level, of agrotouristical arrangement works in the locality

RESEARCH CONDUCTED IN THE EXPERIMENTAL FIELD, ON FERTILITY OF THE PSAMOSOIL IN THE DANUBE LOWLAND (AREA POIANA MARE-DOLJ)
In order to test the productive ccapacity of sandy soils from Poiana Mare as well as the way they respond to fertilization there were carried out two monofactorial experiments: one experiment was located on an eutric sandy soil (typical) placed on the tip of the dune and the second one was set up between dunes on a wide place. The treatments were as follows:V1= not fertilized (control);V2= fertilized by N100;V3= fertilized by N100 P60;V4= fertilized by N100 P60 K40;V5= fertilized by manure, 30 t/ha, applied every three years.The experiment lasted three years in a wheat – maize crop rotation.These crops are most frecquently cropped in this area in in the above mentioned crop rotation. The trials have been carried out with irrigation
Transparent and Electrically Conductive Carbon Nanotube-Polymer Nanocomposite Materials for Electrostatic Charge Dissipation
In recent years, nanocomposite materials have been extensively studied because of their superior electrical, magnetic, and optical properties and large number of possible applications that range from nano-electronics, specialty coatings, electromagnetic shielding, and drug delivery. The aim of the present work is to study the electrical and optical properties of carbon nanotube(CNT)-polymer nanocomposite materials for electrostatic charge dissipation. Single and multi-wall carbon nanotubes were grown by catalytic chemical vapor deposition (CCVD) on metal/metal oxide catalytic systems using acetylene or other hydrocarbon feedstocks. After the purification process, in which amorphous carbon and non-carbon impurities were removed, the nanotubes were functionalized with carboxylic acid groups in order to achieve a good dispersion in water and various other solvents. The carbon nanostructures were analyzed, both before and after functionalization by several analytical techniques, including microscopy, Raman spectroscopy, and X-Ray photoelectron spectroscopy. Solvent dispersed nanotubes were mixed (1 to 7 wt %) into acrylic polymers by sonication and allowed to dry into 25 micron thick films. The electrical and optical properties of the films were analyzed as a function of the nanotubes' concentration. A reduction in electrical resistivity, up to six orders of magnitude, was measured as the nanotubes' concentration in the polymeric films increased, while optical transparency remained 85 % or higher relative to acrylic films without nanotubes
