Authors: DOBOS Laura , PUIA Carmen 
Published: December 2021

Crude oil is a highly complex mixture of hydrocarbons amounting to hundreds of individual compounds with different chemical structure and molecular weight plus a series of lower molecular weight compounds other than hydrocarbons (phenols, thiols, naphthenic acids, heterocyclic compounds with N (pyridines, pyrrole, indole, s.o.) compounds S (alkyl thiols, thiophene, etc.) (Zarnea, 1994).
Mineral oil and polycyclic aromatic hydrocarbons (PAHs) creates larger environmental problems. They are considered particularly dangerous.
In this regard, EPA Agency from U.S.A. includes a number of polycyclic aromatic hydrocarbons under 16 priority pollutants, which require special attention. IARC (International Agency for Research on Cancer) has identified 15 types of polycyclic aromatic hydrocarbons including six of the 16 types of PAHs, identifiable by the USEPA as having carcinogenic properties (Chauhan Archana et al., 2008).

Authors: CIOBAN Camelia , RABA Diana 
Published: December 2021

In the paper studied the possibility of extending the validity term of bakery products(croissant) by slowing the aging process them.
For this purpose investigate sorts were packed in impermeable materials to water and water vapor while were stored at temperatures ranging between 15-20°C and relative air humidity below 70 %. By preserving the croissants under proper conditions in special packing: PE, PP, PP sterilized, paraffin paper, ethylic alcohol treated paper and complex material, the validity term has been extended to 7 days at most, when the first depreciation signs of sensorial (taste, colour, smell),and physical (consistency-the core becomes brittle, humidity-the water quantity lowers significantly) properties become evident. The smooth and rigid crust becomes wrinkled, elastic and soft, the odour and the taste gradually disappear and the taste becomes flat or stuffy and sometimes even sour.
The introduction of ethylic alcohol as well as the packing in proper materials determines the extension of croissant validity term to 30 days when the first signs of mould appear.

Authors: MICU Lavinia Mădălina , PETANEC Doru , GIUCHICI Camelia 
Published: December 2021

Wheat grains are, in general, good sources of thiamine (vitamin B1), pyridoxine (vitamin B6), niacin, inozitol, biotin and vitamin E. They also contain important amounts of pantotenic acid (vitamin B5). Vitamin A is absent in wheat grains.The goal of our research was to monitor quantitative changes in hydro soluble vitamins in wheat grains damaged by Rhizoperta dominica.They have published relatively few data about the effects of insect infestation on the vitamins in wheat grains.Insects are one of the main causes of the losses produced in stored cereals and seeds. (Munro,1966). Rhizoperta dominica F. infests cereals and develops inside the grains thus producing the ‘hidden infestation’ of the cereals.
Bio-chemical analyses through modern methods, we used a chromatographic equipment for liquids, model Shimadzu 10 AD-VP.Quantitative changes the lipids and fat acids were monitored on a number of 5 sample variants infested with 25, 50, 75, and 100 insects of Rhizoperta dominica, respectively.According to the results we obtained, we can note that after a month of attack by Rhizoperta dominica F., the quantity of hydrosoluble vitamins destroyed by these differs to some extent, in relation to the number of insects that infested and attacked the wheat sample.After a month from the initial attack we could see that the insects from species Rhizoperta dominica F. degrade in a higher proportion vitamins B2 and B6. 25 insects destroy about 1.39% B1, 3.98% vitamin B2 and 7.84% vitamin B6, and the 100 insects 44.95% more vitamin B2 and 14,15% more vitamin B6 than 25 insects

Authors: MIHALACHE Mircea , ILIE Leonard 
Published: December 2021

Samples from surface and subjacent horizons of main soil types from chernozem to podzol were selected. Both soil colloids and released cations may be retained or deplaced to the depth. The differences of the averages and medians and the histograms of the two horizon properties show the translocation of clay and free sesquioxides and the retention or migration of some nutrient cations.
The deplacement to the depth were charactherized by migration level difference of concentration in the two horizons A2-A1, by the migration index namely the concentration ratio A2/A1 and by migration gradient, the angular coefficient m of linear relation between the content of the same component in the two horizons.

Published: December 2021

The aim of this paper was to study the restraint kinetic of N-NO3 on a sandy soil sampled from Caracal-Olt area. The kinetic study aimed to establish the interdependences between ion exchange-sorption global process and the main factors that influence the retention process on sandy soil granule level, N- NO3 concentration and N- NO3 soil load.
Theoretical studies present in the speciality literature lead to various kinetic models able to give a satisfactory answer for samples regarding dependence between rate determinative stage of ion exchange process and process parameters. The problem becomes complicate when it is necessary to describe mathematically mutual influence of different elementary stages, solving this kind of problems being impossible with the existing models. In this paper it was presented a methodology by which ion exchange process rate is expressed only based on experimental results, that aren’t influenced by changes of ion exchange mechanism during process. The present paper initiates a new perspective in problem approach by offering a new graphical presentation of the experimental data (kinetical maps), after achievieng a proper experiments time table.

Published: December 2021

Pea’s proteins represent a valuable source of edible proteins which are well tolerating by human body, and contain all essential amino acids. Mature pea’s seeds are very rich in proteins that can be extracted in order to be used to improve the nutritional value of other foods.
Pea’s proteins contain several fractions of albumins and globulins. We have used electrophoresis to separate and identify these fractions, to establish the molecular weight of each fraction, and also the proportion between them. The electrophoresis was conducted following the SDS-PAGE protocol.
Using pea protein isolate as sample, we have found a number of 12 protein fractions with molecular weights ranging between 12500 and 140000 Daltons. From these, six fractions are prevalent.

Authors: NECULIŢĂ Mihaela , ŞARPE Daniela , MAZILESCU Vasile 
Published: December 2021

Agriculture is very important for the regional economy. Despite Romania’s great agricultural potential, the agricultural products processing capacity is low because of the outdated technologies. The high fragmentation of the cultivated land in small parts is another obstacle for agricultural development. The low economical potential of small farms and their inefficient management determined the underdevelopment of the agricultural products processing sector.
Romania must quickly adapt the agricultural economy and rural development for a better integration on the Unique Market, using the European funds.

Published: December 2021

Phosphate sorption capability is an important soil characteristic which determines the nutrients dynamics. Research studies on the chemistry of inorganic phosphorus in soil showed that in soil occur several reactions with resulting compounds; these reactions are dependent on factors like soil pH, type and quality of soil minerals, quantity of soil phosphorus and other soil properties.
The work seeks to determine the equilibrium curves by using a thermodynamic study in order to determine sorption degree of phosphorus (P) on soil grains (chernozem from Teleorman area and sandy soil from Dabuleni area) using the isotherm functions Langmuir and Freundlich typically used to describe adsorption equilibrium, at a phases mass ratio soil:water of 1:5 in the pH range 59. KH2PO4 solutions were used as aqueous phases at a concentration range of 10-100.
The Freundlich isotherm was more attractive than the Langmuir isotherm in describing phosphorus sorption by soil. Thus, quantifying the ratio between concentration of P adsorbed on soil and concentration of P in soil solution is an important step for describing the specific adsorption of ions on soil’s charged surfaces taking pH into account. Moreover, these simple isotherms used in describing phosphorus sorption have a significant role being useful for summarizing both the information about a given soil and the effects of a particular treatment involving the same soil.

Using in Vitro Selection to Distinguish Red Clover Mutations that Tolerate Salinity
Authors: VICAS Gabriela 
Published: December 2021

In this paper are presented the results of some research made to obtain cellular lines tolerating salinity from embryogen callus and non embryogen red clover, from the di- and tetraploid genotypes to verify if the potential mutants, shown by us, may manifest some salinity tolerance. Our studies aimed both untreated biological material and chemical mutagens (DES and DMS).
It was observed that salty environment influences in a negative way the development of callus by decreasing growth and by necrosis appearance on areas more or less extended.
Under the aspect of the genotype reaction towards the salinity, the tetraploid cultivar has proved more tolerant, compared to the diploid one.
At a concentration of 0,5% NaCl the percentage of survival of the red clover callus is of 53,2% at Napoca-tetra cultivar, 23,4% at Apollo-tetra and 23,4% at Roxana diplod, respectively 21,0% at Select. At the concentration of 1,0% NaCl the callus growing is strongly inhibited, up to 19,3% at Napoca-tetra, 17,4% at Apollo-tetra and 4,3 and 3,2% at Roxana (2n), respectively Select (2n).
Following the genotypes behavior of red clover, which are potential mutants, resulted after the treatment with DMS and DES, pointed out positive reaction of the obtained callus at these plants, on medium culture with 0,5% NaCl.
The transfer of callus on culture medium with NaCl 1,0% points out also a growing of the callus surface, but in a low percent, especially at Roxana cultivar (2n).

European mistletoe (Viscum album L., family Santalaceae) is native from Europe and is an evergreen, perennial, hemiparasitic shrub that lives on a wide range of woody plants species. The mistletoe has a number of biological effects, such as anticancer, antimycobacterial, apoptosis – inducing, antiviral, and immunomodulatory activities. In the first part of this study, we present the floral and vegetative characters of five varieties of Viscum album ssp. album that are growing on five different host trees (Acer campestre, Mallus domestica, Fraxinus excelsior, Populus nigra and Robinia pseudoacacia).
In the second part, we recorded the UV-VIS spectrum of methanolic extract (400 to 700 nm), to determined the level of chlorophyll a and b, and also the ratio of A280/A340 (to identify which the bioactive compounds is predominantly). We find the diference between the stem and leaves from the mistletoe that are growing on the same host, and also between the mistletoe that are growing on different host trees.

Authors: DE VLIEGHER Alex , CARLIER Lucien 
Published: December 2021

22 commercial mixtures were compared in a mowing trial (complete block design, 2 replicates) in 4 locations during 3 consecutive years. These mixtures contained mainly diploid and tetraploid varieties of Lolium perenne L.. Festuca pratensis Huds., Phleum pratense L. and Trifolium repens L. were also included at various times. 250 - 400 kg N.ha-1.year-1 was used. Dry matter yield (DM-yield), disease resistance and persistence were evaluated. Similar results were obtained for all three performance parameters (DM-yield, crown rust resistance and persistence) of the mixtures as compared with the individual components.
There was almost no relationship between the percentage of diploid perennial ryegrass in the mixture and its persistence (R2 = 0.18). Similar results were obtained for the relation between the percentage of tetraploid perennial ryegrass in the mixture, as well as for disease resistance of the mixture in late summer (R2 = 0.25).

Authors: NEACSU Ana-Laura , TOFANĂ Maria 
Published: December 2021

Food quality and food safety rely on the efforts of all stakeholders involved in the complex chain including agricultural production, processing and transport as well as consume. According to the European Union and the World Health Organization food safety is a common responsibility of all citizens and authorities, beginning from the origins until the moment food reaches consumers tables. This integrated “farm to fork” approach is now a general principle for EU food safety policy.
In order to maintain food quality and safety throughout the above-mentioned chain, there is need for both special procedures ensuring the integrity of food, and monitoring procedures ensuring the finalization of the operations in best conditions.
In the present work, we will underline a few considerations regarding the regulation milestones in Food Safety, having in consideration the Commissions Report on the experience gained from the application of the hygiene Regulations (EC) No 852/2004, (EC) No 853/2004 and (EC) No 854/2004 of the European Parliament and of the Council of 29 April 2004.

Published: December 2021

As the food industry is interested to recuperate the valuable waste such as beer yeast (Saccharomyces cervisiae) and grape seed (Vitis vinifera), both with high nutritional and health promotion effects, new products and processes are expected to be released on the market. The new modern drying technologies used to process natural compounds and extracts aim a protected evaporation under controlled temperatures and immobilization on matrices, in order to keep high concentrations of bioactive compound in the final products. One of the most important technological parameter during the drying process is the Inlet and Outlet Temperature Using Spray Drying (SD) and Fluid Bed Drying (FBD) optimized technologies we obtained beer yeast (BY) and the grape seed extract (GSE) solid forms, demonstrating that functionality is well preserved (by determination of vitamins B and phenolics, respectively) in the final products comparing with the initial, genuine extracts.
Beer yeast and grape seed concentrated forms (stabilized powders and granulated formulas) have emerging consequences in this context and attract the modern consumer for their positive action on health.

The paper presents the results of the researches concerning the influence of the sowing period on the biology and productivity of the Apullum wheat variety made in the agricultural year 2006-2007 at Floresti, Cluj county, situated at the interface between forest steppe area of Transilvania’s Depression and the under humid area closely to Apuseni Mountains.
The sowing date influenced the vegetation period of the Apullum variety which is shorten in proportion as the planting is delayed, taking place between 263 days at the sowing from 15 September and 233 days at the sowing from 30 November.
The forward sowing (15 September) and the late sowing (30 November) determinate an important secrease of production towards the sowing in the optimal period (15 October). At the sowing from the period of 30 September-15 November, the obtained productions are very close and more up, confirming the fact that in the rainless autumn it is recommended to use the late sowing of the wheat.
