A plea for the agrarian law as a distinct and autonomous branch of law
No full textThe hereby article aims at proving the necessity of regulating the agrarian law as a distinct and autonomous branch of
law, given the specificity of the social and legal relationships in the agricultural field. In this context, we consider that
it is necessary to introduce the agrarian law in the academic curricula, as a distinct subject, in the faculties of law, in
the light of the importance of agriculture, juxtaposed with the unionist politics of sustainable development
Poluarea mediului riveran pe cursul superior al râului Tazlăul Sărat
No full textThe paper presents an analysis of the pollution phenomenon in the Tazlăul Sărat River basin. The studies and researches were carried out on the upper course of the river, in the area of Zemeş locality, where there are a series of wells for oil extraction. The floods have morphologically altered the minor river bed, which has influenced the stability of the banks and river basins. Crude oil pipelines are located in the river bank. Field research has analyzed the river sector between "Toderaş" and "Canton of Maxim", which administratively belongs to the commune of Zemeş, Bacău County. The flood of June 2016 had an excessive impact on the stability of oil pipelines, a situation that caused the scrapping and suspension of the pipeline
Oribatid mites fauna and communities structure in halophilous habitats from the Danube Delta biosphere reserve
No full textThe halophilous habitats, commonly found in the Danube Delta Biosphere Reserve, are restrictive habitats for most
edaphic microarthropods; soil with high salt content, excess moisture and deficient aeration are the main limiting
environmental factors. The present study aims to investigate, both from qualitative and quantitative points of view, the
oribatid mite communities in these habitats of DDBR, less approached in previous ecological research. Following the
field research, representative sampling sites were selected, located in the western DDBR, north of the Razim-Sinoe
lagoon complex, between Murighiol and Enisala.
In terms of fauna, the small number of taxa was noticed (14 species, belonging to 12 genera and 9 families); poronotic
oribatid mites are dominant both as number of species and individuals. Humerobates rostrolamellatus Grandjean, 1936,
and also the genus Humerobates Sellnick, 1928 and the family Humerobatidae Grandjean, 1971 are recorded now for
the first time in the Romanian fauna. Oribatid communities are simply structured, with a small number of species and
low specific diversity, indicating a poor stability. In most of the investigated sites Oribatula (Zygoribatula) undulata
Berlese, 1916 is the over-dominant species, holding 46-94% of all individuals. In addition, the frequency and relative
abundance of the immature stages highlights the full adaptation of this species and its bio-indicator quality in relation to
saline soils
Polyovulatory response and in vivo embryo production at the romanian indigenous buffalo, out of breeding season in N-E of Romania
No full textIn recent years, by using Buffaloes breeding biotechnology, it has been found to improve the results obtained in the recovery of embryos produced in vivo. Following limited research in buffalo, the viable embryo production has increased significantly from less than 1 per flushing to 2.5-3.0 in general and over 4 in isolated cases and conception rate following embryo transfer improved from about 10% to about 30-40%. However, the response to superovulatory treatment and recovery of viable embryos following superovulation is still low compared to cattle due to various factors (Tyagi S. 2007). Through this study we want to make contributions regarding the obtaining of invivo embryos and their rate of recovery by the method of washing the uterus at the Romanian Indigenous Buffalo, located outside the breeding season. The breeding season for Romanian Buffaloes in the major buffalo rearing countries appear to extend from September to March. A polyovulation protocol, described by Hafez (2007), with PMSG at the single dose of 2500 IU administered on day 13, one day before the removal of progesterone vaginal devices (PRID), was used. On the 12th day, a dose of PG was also given. Ovarian response showed a rapid evolution of ovaries, follicle count and size, and ovulation. The ovary volume increased by 3 cm on the day of the oestrus and by another 0.5 cm on the flusing day (from 2 / 1.5 cm to 5.5 / 4 cm the right ovary, and from 1.5 / 1 cm to 4/3 cm left ovary). Five follicles were grown on the right ovary and 3 on the left ovary with a diameter of 0.7-0.9 cm. Of which ovulated only 6. Four corpus luteum were diagnosed on the right ovary and 2 on the left. After washing the uterus 6 days after insemination, a number of 4 embryos were recovered and identified in the laboratory. Three embryos came from the right horn and only one left.Depending on the embryonic stage of development and segmentation, two embryos were in the blastocyst stage and two were in the stage of compact morgue with non-homogeneous chromatin. Qualitative assessment of embryos was classified as two high quality transferable embryos and two non-transferable embryo
Valorificarea potentialului economic al masivului Rarău pe baza condiţiilor climatice
No full textThe Rarau Massif is a mountain area exploited for tourism purposes since 1928, but recent climate change requires a reanalysis of the new weather conditions to propose a new economical capitalizing plan.In this paper we analyzed the main meteorological elements (temperature, precipitation, speed and frequency of wind) recorded by the Rarau meteorological station to highlight the economic potential of the area.In the Rarau massif, the air temperature during the summer months has increased, which is favourable for mountain tourism. This hypothesis is also supported by the decrease of the amount of rainfall during the summer. Our analysis shows that the heating of the air is due to the warm wind, predominantly in the east -west direction with relatively slow speeds (2 m/s). Instead, the temperatures have decreased in January -February which supports the construction of one of the longest winter sports slope in Romania
The correlation of the morphological peculiarities of the hindlimb in mammals, concerning the autopodium, depending on the type of ground support
No full textIn digitigrade and plantigrade species, the head of the talus distinctly appears which together with the glenoid cavity provided by the central bone also favor lateral movements, offering better adaptability. The essential differences are observed at the level of the metatarsal head, where carnivores and plantigrade animals have a dorsal hemispherical joint surface, completed by a real crest in the plantar side, delimiting two condyles separated by an intermediate crest. This is essential for the digitigrade and plantigrade type because when the limb takes contact with the ground, the joints hyperextension also occurs and a finger abduction movement, widening the support area
Ash concrete with polystyrene waste
No full textThe paper presents the experimental results of mechanical strengths obtained on the concrete prepared with different
types of wastes. Fly ash was used as cementitious material and polystyrene granules were used as substitution of
aggregates. The properties of concrete such as density, compressive strength, flexural strength and splitting strength
were investigated having in view the waste substitution. The results show that the concrete with fly ash and polystyrene
granules in reduced dosages had characteristics of structural concrete
Studii şi cercetări privind poluarea mediului de către depozitele de deşeuri industriale
No full textThe Moldovan area has a large number of industrial waste deposits containing mine waste, slag, ash, technological waste etc. The presence of the deposit causes the air, soil, subsoil, surface and underground waters, flora and fauna and the mental state of the people to be polluted. The case study made at a landfill site highlights the multiple forms of induced pollution and their serious consequences on the environment. The deposit consists of a mixture of slag, foundry residues,industrial liquids, etc., which are extremely aggressive in air, soil, surface and underground waters. Physical and chemical indicators analyzed for soil in the area adjacent to the landfill were pH, Cd (cadmium), Mn (manganese), P (lead), SO4 (sulphate),etc. The pollution phenomenon affects all forms of environment in a serious form and the impact is indefinite
Wheat response to microbial improvement of soil
No full textIntegrated farming systems have microbiological bases in soil, microorganisms having the ability to govern nutrient
flows to and from plants. Improvement of production is based on calibration and balancing of circuits driven by
rhizosphere microorganisms. Bioproducts have the role of supplementing microbial groups with a role in promoting
plant growth. The purpose of the paper is to determine the global reaction of two wheat varieties to the application of
bioproducts based on active microorganisms. The over- and underground growth of plants and the synthetic indices
resulted from them were followed. Development parameters are significantly influenced by the application of
bioproducts. In general, autumn wheat variety has a higher developmental balance than the spring one. For autumn
wheat the presence of the microbial consortium caused the plant to transfer significant amounts of resources to the stem.
The biological bases of spring wheat give it an oversize increase much higher than the winter wheat. A possible
explanation for the growth and gradual development of plants is the provision of organic substances in a constant flow
from both sides. For microorganisms, this situation has led to their proliferation irrespective of the presence of other
organisms, and for the plant has ensured normal growth and development. Also in the case of spring wheat, the
correlation between the stem and the root is lower than in the autumn one. The autumn variety has a clustered
development, with an evolution in favor of the stem in the early stages of vegetation, and then leads to a stronger
development of the root
One and a half century of agriculture in Dobrogea. The country between The Danube and The Sea
No full textIn 2018, the Romanians celebrate 100 years since THE GREAT UNION, but also 140 years since Dobrogea's union
with Romania. This paper tries to review the main stages of Dobrogea’s agriculture throughout this period. In 1878,
after the Russian-Turkish war and Romania’s independence war, the Berlin Congress of the European countries decided
to unite Dobrogea with Romania. As a result, on November 14, 1878, the Romanian army, under the leadership of
Prince Carol, entered Dobrogea, not as conquerors but as the rightful owners of a land granted by history. In order to
capitalize the land, the Romanian administration began the colonization process. Order was made in the legal status of
agricultural holdings through a series of reforms, culminating in the great agrarian reform of 1921. Throughout this
period, agriculture had modernized and adapted to the requirements of the market economy. After World War II, the
Communist dictatorship followed, which for 40 years took its citizens the right to private property on the land. After
1989, it reverted to market economy principles and, since 2007, the European Union's agricultural system has been
practiced
