(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iași, 2018) Grecu, Codrina; Cojocariu, Mirela; Purcaru, Andrei

It is well known in history that the rapid development of culture, civilization, technology and industry of the population from certain areas of the globe has been favored by a favorable environment,either geographically and climate or from the perspective of the absence of internal or external conflicts, by the presence on their territories of mineral or flora and fauna resources, or even their own human resource. Extrapolating the idea above, this paper seeks, at the smaller scale of a city nowadays, how the environmentally arranged landscape can beneficially influence the overall development of the urbanarea, but especially of its inhabitants, from the point of view of physically-psychological-sanogenic, but also socially and culturally, with examples from the city of Iasi

Relationship between urbanism and landscaping

(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iași, 2018) Dascălu, Doina-Mira; Cojocariu, Mirela; Grecu, Codrina; Negrea Pașcu, Roxana

From the simplest forms of habitation organization to the most complex human settlements, it can be seen how nature was or was not integrated into urban space. A human settlement cannot be reduced to a simple accumulation of construction. The outer space or the space between constructions has specific functions and is governed by specific laws. The importance of this space in the complex structure of human settlements can be highlighted by reviewing the history of urbanism. In this process of evolution of the spatial component, an important role is played by the passageways or the urban transition areas. These areas are those where green spaces and/or landscaped zones are gradually emerging, increasingly performing more and more important functions. Why in this early age of the new millennium landscaping process has become an extremely effective tool of the urban science? Because in the context of accelerated pollution and degradation of the Earth, the urban regeneration is possible by interfering the urban and landscaping means of action, through functional solutions stemming from the real needs of the environment and inhabitants.

Research on the economic efficiency of the agricultural ecosystem under agro-technical measures to crops of corn

(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iași, 2018) Bacău, Cristina-Viorica; Gîdea, Mihai; Mihalașcu, Costel

Against the background of global warming, increasing pollution levels and requirements for limiting the use of fossil fuels, demand for biomass has increased. For testing the energy efficiency of the agro ecosystem in the Experimental Farm of the Moara Domneasca, Găneasa, Ilfov County, a bifactorial experience has been achieved in which Factor A = Nitrogen Fertilization Level (N) and Factor B = Irrigation Level. Increasing the level of nitrogen fertilization (N) on the same phosphorus soil conditionshas led to statistical gains of both the main production of grain production, thus maintaining land use for agricultural production, as well as secondary production that has potential for use as biofuel. The increase in the level of irrigation (a2, a3) led to a very significant increase of the grain yields (kg / ha) and of the biomass production. Analyzing the economic efficiency of the ecosystem under the influence of the technological measures, it is noted the significant increase of all economic indicators compared to unfertilized (b1) or non-irrigated (a1) control, increases are proportional to the applied nitrogen dose and watering standard.

Preliminary results regarding electrostimulation of the physiological rithm by using continuous electric current in pepper crops

(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iași, 2018) Gheorghițoaie, Mădălin-Vasile; Achiței, Vlăduț; Teliban, Gabriel-Ciprian; Stoleru, Vasile

The goal of this research was to study the usefulness of the continuous current in a sweet pepper crop, the process that aims to accelerate the rhythm of flowering, fructification and ripening, obtaining more early harvests in conditions of food safety that does not affect consumers' health. Thus, by connecting the plant to a continuous current that will generate a negatively charged mangentic field, it stimulates the absorption from the soil of the essential mineral elements in terms of good development of plant growth and development. The method consists in creating a flow of electrons circulating from the plant's base to the top. This field that will be loaded in turn with negative electrical load, has the property to attract positively charged electrical loads. The most favourable results were achieved in the case of a continuous current of 1.5 V, the positive pole being located in the apical area, and the negative one being inserted at the base of the plant's stem.

The present paper places plants as a coordinating element in the irrigation ensemble, where they can provide data on moisture and can achieve numerically the limits to which their biological systems operate optimally. The genesis of this system is based on the intensity of the electrical current measured between the two electrodes, intensity which is in relation to indirect proportionality with the hydric deficit measured at the sap level. The plant's water supply was measured using two electrodes, represented by medicinal needles specifically treated to prevent oxidation during use. In order to highlight the currents of low intensity, a galvanometer was used.On the basis of this method were performed measurements demonstrating the decrease of the intensity of electrical conductivity inversely proportionate to the water content, the average in the group subjected to stress hydric (L2) on day 3 with the value of 6.22 Amp, gradually decreasing the As the period during which it was subjected to a hydric deficit increased, reaching 3.92 Amp on day 4, 2.54 Amp on day 5 and 1.67 Amp on Day 6, compared to the normal average of 6.35 Amp.On the last day, the stage in which the group subjected to a lack of water (L2) was hydrated, a return was found in terms of the intensity values at the average of 3.44 Amp, which strengthens the relationship between the variation of the two characteristics.

Studies and research on pollution of the industry energy on the green area of the city

(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iași, 2018) Luca, Mihail; Luca, Alexandru-Lucian

The urban environment is heavily influenced by the pollution generated by thermo-power plants. Their work program and the fuels used generate intense pollution of urban green spaces. In the case of thermoelectric power plants on gaseous and liquid fuels (methane + fuel), the emissions of the gases (CO, NO, NO2, SO2), which by hydration produce acids, occur in the atmosphere. Acid rains work on green areas continuously over the dominant wind direction. The case study conducted in the Iasi areaindicated the pollution area, the concentrations of the pollutants and the lengths of the noxious transport in the considered area. The study of the dispersion of noxes in the atmosphere is done by modeling the functional phenomena of the polluting sources.

Considerations on the valuation rain -waters to waterings of the "green areas" of city

(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iași, 2018) Luca, Alexandru-Lucian; Luca, Mihail; Chirica, Ștefania; Toma, Daniel

Rain-waters have a problem of exploitation in any sewer system. European rules require the development of sewage systems for urban wastewater in Romania. Storm water must be collected and discharged separately from domestic and industrial wastewater. Some of the rainwater can be harnessed in the collection area by using them to supplement the volumes of water required to extinguish the fire. Rain-waters can be used to wash streets and platforms in localities. But an effective recovery of rainwater takes place in irrigation systems of green spaces. The sewer system consists of collectors, main collectors and storage tanks. The irrigation system of green spaces consists of water tanks, pumping stations and pipeline networks for the transport and distribution of water. The watering methods adopted are aspersion, micro-spraying, dripping and underground watering. The case study completed confirms the desirability of using pluvial waste water when watering green spaces.

Considerations on the ground pollutant effect on drinking water conveyance pipes

(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iași, 2018) Chirica, Ștefania; Luca, Mihail; Lateș, Iustina

The water supply system pipe networks are made of tubes and pipes joined by sockets or welds, on which a series of fittings are placed. The construction unit interacts with the degradation factors present on site. The research has shown that the main external mechanisms of pipe degradation result from the physico-chemical properties of the site's ground and external loads. External processes, which occur on the ground, lead to the degradation of the pipe network through the appearance of micro-pores, pores, fissures or cracks. Under specific operating conditions, water emission areas can become entering pathways for pollutants from the external environment inside the pipeline, causing the contamination of the drinking water conveyed. Considering the hydro-climatic phenomena in recent years, which have put pressure on viable drinking water resources, it is necessary to identify the external sources of degradation of the pipe networks.

Evaluation of different methods for drying of Eryngium planum and Echinops ritro flowers

(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iași, 2018) Moraru, Mihaela; Brînză, Maria; Chelariu, Elena-Liliana; Draghia, Lucia

The plants of the genres Eryngium and Echinops assume distinctive ornamental qualities, being appreciated both in landscaping design and in floral art. In this paper are presented results regarding the drying of cut flowers obtained from Eryngium planum and Echinops ritro, with the purpose of utilization as immortelles. The drying of the inflorescences was achieved by two methods, respectively, simple drying in the darkand using a desiccant (silica gel). The results obtained showthat for both species,the drying time is shorter and the water is eliminated in a higher percentage when using silicate. Eryngium inflorescences dried with silica gel have more intense blue tone; at Echinops ritro have been obtained the immortelles with similar aesthetic features with both drying methods.

Preliminary studies regarding the use of vegetable species in the concept of urban gardens

(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iași, 2018) Hangan Istrate, Ana-Maria-Roxana; Gache Lungu, Mirabela; Teliban, Gabriel-Ciprian; Stoleru, Vasile

This paper presents a literature preview regarding the use of vegetable species in the concept of urban gardens. The designing of the utilitarian gardens dates back from the antiquity when they were particularly important as a source of food. With the emergence of the concept of "edible landscaping", which promotes the use of edible plant species along with ornamental plant species in landscaping, the utilitarian garden has acquired aesthetic valences as an integral part of the green space set up on private property in the urban area and not only. Starting from the desire of people to have a place to produce some of the necessary vegetables and aromatic plants in the small space around the houses and to enjoy a recreation space, will be studied different systems of use of vegetable plants in order to develop concrete measures for the development of decorative vegetable gardens in the private environment in urban and periurban areas, taking into account the possibilities of association of the leguminous plants in raised beds
