(Editura ”Ion Ionescu de la Brad” Iași, 2013) Arhip Însurățelu, Ioana-Cristina; Murariu Cojocariu, Mirela; Draghia, Lucia; Luca, Ana
Originating from tropical areas of Africa and Asia, Zantedeschia and Gloriosa genus include species which are grown in protected areas, when present in temperate climate conditions, as plants in pots, or as cut flowers. Gloriosa is growing lush and pretentious to environmental factors, especially to light intensity, which influences the quality and quantity of flowers. Zantedeschia, more common known as Cala, is very appreciated as cut flower. This paperwork presents aspects of the culture in pots of Zantedeschia hybrids (‘Picasso‘, ‘Cameo‘, ‘Black Eyed Beauty‘ and ‘Black Star‘) and Gloriosa superba species and its four cultivars (‘Rotschildiana‘, ‘Greenii‘, ‘Lutea‘ and ‘Orangerie‘). Biological material was imported from Holland and observations were made on underground organs characteristics (diameter, mass), planting period up to the appearance of floriferous stems, production of flowers/plant.

Modeling and optimization of a real textile effluent treatment by sorption onto sawdust as ‘low cost’ sorbent
(Editura ”Ion Ionescu de la Brad” Iași, 2013) Zaharia, Carmen; Șuteu, Daniela
An experimental planning of sorption on sawdust (as ‘low cost’ sorbent) applied for a real textile effluent (i.e. collected after the dyeing and rinsing steps of cotton fabrics manufacturing) is discussed using a 23 central compositive rotatable planning. It was elaborated an empirical model considering the sorbent concentration, pH and temperature of textile effluent as indepen-dent variables, while the decoloration degree (color removal) was chosen as optimization criterion. The highest decoloration degree was 65.815 % after 24 hours of continuous static sorption. The proposed model was found adequate for the real effluent treatment by sorption on sawdust as primary treatment step.

Use of remote sensing in monitoring water quality
(Editura ”Ion Ionescu de la Brad” Iași, 2013) Slave, Camelia; Man, C.M.; Rotman, A.L.; Dima, C.I.
Environmental pollution has become one of the most debated issues of the contemporary and one first order for the company management. Man and environment are inseparable entities, human existence is dependent on the environment, and environmental factors (air, water, soil) may change as a result of their use by humans. Such pollution occurs, dimension of life, in the course of which some products resulting from physiological processes and human activity and animal residues are likely to interfere with the welfare of the nature and quantity. With the great scientific advances, the amount and nature has changed dramatically. In recent decades, the degradation of the environment from all over the planet has fared increasingly worrying amount of pollutants reaching in excess of imagination. Removing pollution is a problem that causes error correction To study the effects of water pollution on the river, we chose Arges River. The aim is to show the changes caused by pollution on water quality using remote sensing images.

Thermodynamic calculations of complex chemical equilibria in soils containing aluminium minerals
(Editura ”Ion Ionescu de la Brad” Iași, 2013) Povar, I.; Spînu, Oxana
A thermodynamic method for calculating complex chemical equilibria in soils containing aluminium minerals under the real, non-standard conditions has been developed. The expression for calculating the change in real Gibbs energy was deducted. Heterogeneous systems with simultaneous reactions involving aluminium soluble and insoluble (minerals) species have been investigated. Comparisons of thermodynamic stability of Al oxysulfate minerals and gibbsite were carried out. The developed approach for calculating the Gibbs energy may be successfully applied for the prediction of complex chemical processes in soil.

Noise pollution monitoring in Cluj-Napoca parks by GPS mapping
(Editura ”Ion Ionescu de la Brad” Iași, 2013) Singureanu, Valentin; Husti, Anca; Neacșu, Ioana; Moldovan, G.
According to demographic statistics afferent for 2006, in the city of Cluj-Napoca were recorded in the local government 305.620 residents, resulting an average density of inhabitants per km2, located around 1771. The most important Romanian auditor in acoustic measurements, show that in all cities with over 250.000 inhabitants, there we have about 2.9 million people exposed to noise beyond the limit set in the auditing standards. Thus, for more than 60% of the population, quality of life is considerable affected by phonic pollution. The determinations aimed the existence of noise pollution in Cluj- Napoca parks based on standard measurements using a digital sound level meter and a ground GPS recording data such as: noise level day-evening-night Lzsn in decibels (dB), night noise Lnight. The data collected were entered into mapping programs resulting maps related to real databases, efficient in future landscape works for reducing this type of pollution.

The ecological evaluation of the landscaped projects in software procedure
(Editura ”Ion Ionescu de la Brad” Iași, 2013) Pohoață Lupu, Oana; Grădinariu, G.
The urban landscape architecture and territorial establishment are ensembles with diverse functions, in harmony with the human life and the environment. Vegetation, with all its features, constitutes the bond that physically incorporates the urban buildings. In the competitions of projects proposals, the evaluation in order to select the recipient solution takes into account some factors: the implementation of the functionality criteria, aesthetical value, costs etc. An additional evaluation of the projects method, that of the ecological impact, can be accomplished digitally, by means of some subroutines created under the license of original software, through out a sequence of commands. The procedure takes into account the capacity of the species introduced in the project to reduce the level of pollutants (Pollution Removed, Tree Rainfall Interception, Carbon Storage, etc.), and the evaluation of its beneficial effect both on the human life quality and on the physiological parameters of plants (Canopy Cover, Leaf Area, Tree Condition, Leaf Biomass).

Functional and aesthetic landscape quality: urban square criticism – Focșani
(Editura ”Ion Ionescu de la Brad” Iași, 2013) Lazăr Bâra, Alexandru-Paul
Middle size provinces reflect in a dramatic manner the gap between Romanian landscape culture and the European urban standards. Environmental culture lacks, the shallow civic involvement, the lack of management and administrative culture and the shame toward national and local models are only some of the symptoms of a crushed society with major landscape impacts. This paper analyses urban square designs in a representative town using aesthetic, environmental and social criteria, in an attempt to trace specific responsibilities for landscape architects targeting urban sites. In the end it is concluded that stronger landscape architect’s professional ethics is needed to suSLort cultural development, urban life quality and social wounds healing.

The aesthetic and symbolism of architectural landscape forms
(Editura ”Ion Ionescu de la Brad” Iași, 2013) Grecu, Codrina; Pohoață Lupu, Oana
If for the man "in the beginning was the word", and for each word he can find a grafic representation by symbols, then is shore that Nature "speaks" through form, color, light, sound, - whatever suggestive expressions of life that we humans are made it with native perception sensibilities. Art of landscape planning was subject more or less to the same attributes of Nature, loaded by ancestral, sacred or secular symbolism, with traditional or ganed value. Knowledge of symbolic forms: geometric or tortuous, natural or man-made, pure or vicious, lead landscape designer and architect, through educated or intuitive actions to create the necessary space for human life, dictated by aesthetic and utility.
