Authors: Sandu Mirela , Virsta Ana 
Published: September 2018

AbstractThe paper presents an original research regarding the risk for human health in the area of Ploiesti city using SADA software - Spatial Analysis and Decision Assistance. Due to the high level of toxicity, international legislation provides the list of PCBs compounds to be monitored: PCB28, 52, 101, 118, 138, 153, 180. Sample collection was made in 22 points including public green gardens, residential areas, roadsides and industrial areas. The chemical analyses were conducted in the Laboratory of National Research and Development Institute for Soil Science, Agro-Chemistry and Environment from Bucharest, according to an own analytical method adapted after EPA. According to the Romanian standards, PCBs were elevated across industrial regions near urban and industrial sources. The concentrations of PCBs overcome the normal values in the most sampling points and the area presents a potential of risk for people. Local authorities should address the human health threats from urban and industrial soils in Ploiesti city.

A Potential Method of Chemical Remediation of Arable Lands Polluted with Heavy Metals
Authors: Vrancuta Luciana 
Published: September 2018

Abstract
Soils from agricultural areas are under anthropic pressures, one of the causes being atmospheric deposition of heavy metals. In order to prevent that diffuse pollution affects the soil for long term it is important to reduce the releases of pollutant from air and water. In this paper it was analysed a potential method of chemical remediation applied to the case of an accidental situation of arable soil pollution with heavy metals. The technology of remediation proposed is based on a chemical fixation by adding a reagent into the contaminated soil where it reacts with heavy metals and form insoluble complexes. The organic reagent is one of the best-known and most frequently used in extraction and trace analysis. So, the chemical remediation proposed could decrease the migration of heavy metals in soil and subsequently, in water, plant and other environmental media.

Abstract
The investigations were aimed to establish the comparative efficiency of four disinfectants (Aquadez, Ecocide S, Virocide and Na OH) used for the disinfection of cattle farm of State Agrarian University of Moldova. According to the classical methodology, the disinfectants have been used in concentrations which were recommended by the producers. Following this, lavages were collected from different supports and equipment of the cattle farm before sparing of the disinfectants and one hour after the contact of the disinfectants with the substrates. In this context samples were taken from places as the feeding space for animals and the rest area, cows’ milking rooms and the milk collection rooms. Afterwards, the samples have been inseminated in laboratory conditions for establishing the afterwards disinfecting effect on the farm. As a result, the microbiological investigation demonstrated that concentrations which were recommended by the producers and double concentrations of disinfectants don’t have satisfactory 100% of the anti-microbial and antifungal effect. For all disinfected places with the mentioned disinfectants colonies of microorganisms grew on nutrient media, especially bacterial forms as Streptococcus, Staphylococcus and microscopic fungal. Following comparisons, Ecocide S 3% and Na OH 3% had a higher efficiency than Aquadez 3%. The after application effect of Aquadez 3% established the presence of Salmonella, E. coli colonies grown on nutrient media as well as, Streptococcus and microscopic fungal.

Published: September 2018

Abstract
The decrease of variability sources and the genotypes instability as a result of climate changes from the last years were issues addressed in the breeding programs. For breeders the stability of some parameters like plant height is very important in selection process, therefore the influence of climatic variations it is aimed to be reduced by genetic response of the genotypes. Semi-dwarf genotypes are preferred by breeders because in this way is avoided the lodging risk. A set of 307 mutant and mutant/recombinant wheat DH lines, along with parental genotypes, was analyzed in three different years for plant height and the semi-dwarf selected lines were evaluated for stability of this parameter. The material was also analyzed for the presence of Lr34, or genes and 1A/1R translocation. In our study the reduced plant height and its stability was not associated with any of the genetic background

Abstract
The purpose of this paper was to compare the composition (weight % of total identified FA) in saturated (SFA), monounsaturated (MUFA) and polyunsaturated (PUFA) fatty acids from 3 food matrices (sunflower oil, palm oil and lard) by 2 different techniques, gas chromatography - mass spectrometry (GC-MS) and nuclear magnetic resonance (NMR). For GC-MS technique, fatty acid methyl esters (FAMEs) identification in the samples was performed by comparison of the retention times (RT) and the mass/charge (m/z) ratio characteristic of each FAME component in the reference standards used (F.A.M.E. Mix C4 - C24 and SRM®2377). FAMEs quantification from food samples was realized by applying correction factors calculated based on reference standards. NMR spectra were recorded on a Bruker Advance 400 MHz spectrometer, operating at 9.4 Tesla corresponding to the resonance frequency of 400.13 MHz for the 1H nucleus. The NMR spectra was recorded directly on the oil without any sample preparation. The difference between the mean values of the fatty acids content determined by GC-MS and NMR was not more than ± 15% for sunflower oil and lard, and ± 6% for palm oil.

Abstract
The decontamination and detoxification of pesticides-contaminated soils is a tough task, due to their persistence and mobility. Camelina sativa is resistant to pests and weeds which affect similar crops mostly due to its unique defence system, attributed tocamalexin and metoxi-camalexin. Considering this, camelina may be cultivated without input of pesticides, but what happens if camelina is cultivated on an already pesticide-contaminated soil? The purpose of the study is to analyze the Camelina sativa potential to concentrate or not the residual pesticides from the soil in its seeds.It was assessed the level of pesticides from the soil on which Camelina sativa-Mădălina variety was cultivated and from the resulted seeds. The quantification was done using a GC-MS-MS equipment. In the soil it was found a total amount of 0.03 mg/kg of pesticides consisting in: o,p-DDE, p,p-DDE, o,p-DDD, o,p-DDT, p,p-DDT, from which 81.4% was p,p-DDE. All the signals registered for camelina seeds were below the LOQ of 0.005mg/kg. Camelina sativa-Mădălina variety can be cultivated on soils contaminated with DDT and its metabolites, minimizing the risk of pesticides translocation.

Published: September 2018

Abstract
The excessive use of synthetic pesticides for plant pathogens control could cause possible harmful side-effects to humans and animals, environmental pollution, residual toxicity, affects soil characteristics or induce the development of fungal resistance. Alternative ways for fungal contamination control involve natural products, based on microorganisms, many of them being already available for use. The selection and characterization of new biological agents useful for plant pathogens control are permanent goals for plant protection researches. In the last decade, several studies revealed that Streptomyces species are promising biocontrol agents against a wide range of phytopathogenic fungi, including Fusarium spp., one of the most important wheat pathogens. In our study, 60 strains of Streptomyces spp. were isolated from soil or compost and evaluated for in vitro antifungal abilities by dual confrontation method. At least 30% of the isolates presented inhibitory activity against F. culmorum and F. graminearum. The bacterial strains were also tested for their ability to produce various bioactive compounds, possible involved in fungal inhibition. The capacity of some of the bacterial isolates to produce cellulases, amylases, lipases and volatile metabolites was proved. In addition, a new screening method for chitinases production was developed, based on the use of a combination of Congo red and Lugol solutions, which allowed the detection of chitinases in several Streptomyces spp. strains. Moreover, the reduction of the level of some Fusarium mycotoxins was detected by HPTLC analysis. As a conclusion, antagonistic interactions between Streptomyces isolates and fusaria could involve antibiosis, competition and parasitism and suggested that at least some of the selected isolates could be used in obtaining biological control products.

Boyd (Chebyshev and Fourier Spectral Methods, 2ed, 2000) has presented a method for calculating the optimal approximate amount of L and we have used the same method for calculating the amount of L. With the aid of quasilinearization and FRC2 collocation methods, the equation is converted to a sequence of linear algebraic equations. An excellent approximation solution of y(t), y′ (t), and y ′ (0) is obtained.

Abstract
Let T(M; x,y) = ∑ij Tij xiyjdenote the Tutte polynomial of the matroid M. If Tij is a corner of T (M; x, y), then Tij counts the sets of corank i and nullity j and each such set is a cyclic flat of M. The main result of this article consists of extending the definition of cyclic flats to a pair of matroids and proving that the corners of the linking polynomial give the lower bound of the number of the cyclic flats of the matroid pair.

Published: September 2018

Abstract
The health condition of rolling bearing can directly influence to the efficiency and lifecycle of rotating machinery, thus monitoring and diagnosing the faults of rolling bearing is of great importance. Unfortunately, vibration signals of rolling bearing are usually overwhelmed by external noise, so the fault frequencies of rolling bearing cannot be readily obtained. In this paper, an improved feature extraction method called IMFs_PE, which combines the multivariate empirical mode decomposition with the permutation entropy, is proposed to extract fault frequencies from the noisy bearing vibration signals. First, the raw bearing vibration signals are filtered by an optimal band-pass filter determined by SK to remove the irrelative noise which is not in the same frequency band of fault frequencies. Then the filtered signals are processed by the IMFs_PE to get rid of the relative noise which is in the same frequency band of fault frequencies. Finally, a frequency domain condition indicator FFR(Fault Frequency Ratio), which measures the magnitude of fault frequencies in frequency domain, is calculated to compare the effectiveness of the feature extraction methods. The feature extraction method proposed in this paper has advantages of removing both irrelative noise and relative noise over other feature extraction methods. The effectiveness of the proposed method is validated by simulated and experimental bearing signals. And the results are shown that the proposed method outperforms other state of the art algorithms with regards to fault feature extraction of rolling bearing.
