Martinez, Chois Claudia. „Réhabilitation des sols pollués par les éléments traces métalliques grâce aux bactéries du sol associées à la rhizosphère de Miscanthus x giganteus“. Thesis, Université de Lorraine, 2012. http://www.theses.fr/2012LORR0323/document.
Der volle Inhalt der QuelleSoil is a nonrenewable resource to maintain because of its socio-economic and environmental importance. However, (bio)industrial activities can degrade soil and cause the appearance of persistent pollution brownfields. The ability of Miscanthus x giganteus to adapt to brownfield soils polluted with heavy metals (HM), while promoting the consolidation process of bioremediation of polluants, without causing a negative impact on the environment, is studied. Soils from Lorraine region (France), very affected by past industrial activity, are used. Considering the complexity of soil-plant-microorganisms relationships, various complementary assessment tools (i.e. in vitro,mesocosm and field) are used to determine the response of each component and their interactions, and thus deduce the sustainability of the method. The culture of M. x giganteus has great potential for rehabilitation of brownfield soils having a multimetallic pollution or mixed (+PAH) with a double benefit: phytostabilisation of HM at the root level and the production of biomass reclaimable (limited transfer of HM). The plant does not alter the characteristics of the soil involved in the mobility of HM (pH, CEC) ; but changes from those related to soil fertility, toxicity (liquid fraction) and the accumulation of HM by other organisms attest to the interaction of the plant with the elements that would make them more available. Plant's activity is causing associations with soil bacteria, for which the phylopes potentially métalloresistants (Zn, Cr) seem common in soils used
Soulier, Hélène. „La friche urbaine : déchet ou ressource ?“ Paris 8, 2006. http://www.theses.fr/2006PA083669.
Der volle Inhalt der QuelleEver since the end of the eighties, so-called « urban wasteland » refer to forgotten spaces in cities. They came after industrial, portuary or rail wasteland, which were seen as territorial consequences of the economical crisis. We try here to redefine this concept through its social and economic context. We examine then how it met the landscape issue, although they’re strangers to each other. As a consequence, the main idea of this research suggests that these non-planned urban wasteland lead to modify the practice of landscape design. The thesis presents thoughts and practices of several actors (institutions, clients, landscape architects) who had to focus on urban wasteland in their proper way. It enhances first the different approaches related to the kind of practice and its cultural background and then the place of urban wasteland study in the landscape practice. A few topics are consequently re-defined: site, landscape project and their relation to each other

Der volle Inhalt der QuelleIn this work, we studied short-range photoassociation of rubidium atoms. We realize trap-loss spectroscopy in a magneto-optical trap of 85Rb using high power fiber laser, which had around 1MHz linewidth and 50W power at 1060nm to 1070nm interval. Two vibrational levels of the 0u+ excited potential were observed (v=137 e v=138). Besides that, we measured the lifetime of a crossed optical dipole trapped. As expected, the lifetime is shorter when the laser is tuned on resonance. A theoretical model predicts the molecular distribution in the vibrational levels of electronic ground state. The results suggest us perspectives to produce Rb2 molecules in the ground vibrational state.

Der volle Inhalt der QuelleIn this work, we present the construction of a new experimental system for trapping atoms and molecules. It is an all optical crossed dipole trap, formed by a fiber laser with 40 W of power at 1064 nm. In this system, we have trapped K and Rb atoms as well as Rb2 molecules. We have carried out two experiments in this new system. In the first, we studied the temporal evolution of atomic samples of different isotopes, 85Rb and 87Rb, in the crossed trap dipole. We were able to measure for the first time the hyperfine-changing collisions of atoms in the absence of resonant light, and we have observed photoassociation of atoms by the dipole trap laser beam. In the other experiment, we have developed a technique that allows us to study the trapped molecule population decay in the trap. It was also observed the molecule population decay in the presence of atoms prepared in a given hyperfine state of the ground state. These results together with a theoretical development may suggest us new perspectives towards the production of a system that can produce and trap KRb molecules in the ground state 1Σ+ (v = 0).

Der volle Inhalt der QuelleThe current problem of disposal of electronic waste stimulates research aiming at the reuse of this type of waste in the manufacture of new products or existing processes. The disposal of computer monitors and televisions based on the technology of cathode ray tube (CRT) is not simple, since they contain heavy metals and there are few recycling alternatives nearby the consumer center, generating an unsolved environmental liability. The CRT corresponds to approximately 85 wt% of a computer monitor, and is composed by three silicate glasses with different compositions, in the approximate proportions (wt%): 65% panel, 30% funnel and 5% neck glass. Among the different glasses of which the CRT\'s are made, the panel has higher percentages of alkali and alkaline earth metal oxides, which thus give them potential to be used as frits substitute in the formulation of ceramic glazes. An additional advantage is the fact that these heavy metals are stabilized in the form of oxides, presenting minimal dissolution after sintering and vitrification. In the present work, the chemical compositions of a CRT\'s panel glass and glaze frits were characterized by XRF and ICP-AES. Then, the value of thermal expansion coefficients and viscosity were calculated as a function of temperature using empirical models that relate such properties with the glass chemical composition, aided by the SciGlass software. The partial replacement of frits for CRT\'s panel glass was experimentally tested in the composition of a typical transparent ceramic glaze. Aqueous suspensions containing 10 to 40 wt% of CRT\'s panel glass as a substitute for the traditional frit were prepared and applied on the surface of substrates formerly obtained by pressing a clay raw material into plates. Subsequently, the plates were fired following a thermal treatment similar to the used industrially. The resulting thermal expansion coefficients were characterized by dilatometry. The glaze viscosity was measured at high temperatures (low viscosities). The color and transparency of the glazes after firing were characterized by colorimetry. In a comparative analysis, the substitution of 20 wt% of frit by CRT\'s panel glass resulted in ceramic tiles with properties equivalent to those of the commercial glazes.

Der volle Inhalt der QuelleSince the beginning of industrialization, many wastes contaminated with metal(loid)shave been released into the environment without any management. Mining has generated huge quantities of fine, unconsolidated waste, rich in metal(loid)s, stored in tailing or in settling ponds and then left to be abandoned in the open air without any development or protection. This waste remains on site exposed to strong wind and water erosion leading to the spread of contaminated particles in the various environmental compartments (soil/sediment/water/atmosphere). First, the study of the fate of metal(loid)s in contaminated soils related to mining activity revealed the presence of associated environmental and health risks. The results highlight that (i) the geochemical behaviour of the three elements (cadmium, zinc and lead) is different, (ii) the speciation of these elements clearly changes between tailings and soils, (iii) Pb lead can cause adverse health effects for children. In a second step, two techniques for the rehabilitation of contaminated sites were apprehended: (i) in the context of soil refunctionalization, the potential for phytostabilization assisted by organic and inorganic amendments of plots contaminated with Douglas fir, as well as (ii) ex-situ recovery by attacking mining waste by alkaline way, which involves reducing the pollution source
Birks, Charlotte. „Des friches aux parcs : La loisirification des espaces verts“. Thesis, Nantes, 2019. http://www.theses.fr/2019NANT2034.
Der volle Inhalt der QuelleMore and more meadows, fallow lands, forests, ponds or river banks are being transformed in order to be used for outdoor leisure activities (walking, running, water sports, etc.). Hidden behind the increase in amenities (paths, benches, car parks, etc.), institutions and their agents have historically monopolized the management of these areas when transforming them into leisure “parks”. Whether they be elected councils, civil servants, private landowners or company directors, these public and/or private actors have created a wide range of responses within political and economic contexts that are favourable to these kinds of land transformations. The analysis is based on three case studies : a private estate owned by a French aristocratic family, a public park managed by a local Town Council and a leisure park run by a multinational sporting goods corporation. This study, undertaken for a doctoral thesis, shows that, despite differences that seemingly separate these parks together with their landholders, the creation of green leisure parks Whether they be elected councils, civil servants, follows a similar process of land institutionalizion. This specific process is hereby called the “leisurefication” of nature. Results show similar processes of labour division, reallocation and commodification of land

Der volle Inhalt der QuelleThe thesis provides a comprehensive analysis of the policies and instruments used to redevelop the abandoned land in both countries, within their national framework. The first part focuses on the origins of the state strategies of regeneration. The integrated aproach and the linkage between remediation and urban regeneration are discussed with particular attention. The next part shows the regeneration as an element of local development policies. The third part focuses closely on legal instruments used for the urban planning and to manage the redevelopment projects. The french instruments, specially the ZAC, are studied with the aim to offer some principles that could be adopted into the Czech conditions. The case studies in the fourth part deal with the issues discussed in the previous part. Its aim is to evaluate the efficiency of studide instruments in the redevelopment process undertaken on different scales and administration levels

Der volle Inhalt der QuelleIn this paper, we present an experimental setup to simultaneously trap atoms of K and Rb in a crossed optical dipole trap. This accomplishment required the individual study of each atomic species during the project development. This allowed the development of a new technique for loading a dipole trap directly from a magneto-optical trap of 39K, providing evidence of the importance of the hyperfine structure of the state 4P3/2 in the loading process. We also observe and explain the photoassociation process of Rb2 due to the dipole trap laser at 1071 nm, including an isotopic difference between 85Rb and 87Rb. In the sequence, we performed dual species loading of K and Rb and observed the photoassociation process of KRb. A simple theoretical model predicts the final distribution of vibrational levels obtained. The same model provides a potential path to optically pump the molecules and accumulate them in the molecular ground state X1Σ+ (v = 0) for KRb.

Der volle Inhalt der QuelleSince the 1950’s, the conversion of industrial wastelands constitute an important phenomenon in Europe. Even if it is more known as a movement of urban redevelopment, it also holds a particular meaning for today’s cultural and artistic practices. These huge (vast) spaces that were abandoned by science and industries of the modern era start to become the places of alternative expressions which are convenient for exchanges between art, industry and science of contemporary times. Thus, these memorial places‐ through their particular characteristics incarnate the entity of the western contemporary societies. Starting by their facilities, the model of organization of work, and the industrial production approach that they reflect; their factories, laboratories and centers are at the crossroads of several artistic questions. The major objective of this thesis is to analyze the possibility of an interaction between art, science, and industry but also academia within the project of a particular cultural wasteland realized in Istanbul in Turkey by putting the emphasis on social –economicalechoes of such a conversion at urban level. Observing the unique example of Santralistanbul – an initiative of Bilgi University that gave life again to the ancient electricity power station of Silahtaraga‐, the point is to highlight theparticularities of the project and to focus principally on the activities concerning the domain of performing arts

Der volle Inhalt der QuelleDosimetric parameters such as Percentage Depth Dose, Field Profile and Output Factor are necessary in radiotherapy routine, once they can help to improve the quality of the treatment and consequently of the absorbed dose delivered to the tumor. In this work the dosimetric parameters for electron beams of 8 and 10 MeV were measured with the chemical dosimeter Fricke Xylenol Gel for small field sizes (square and circular) and were compared with those obtained with an ionization chamber. The chemical dosimeter signal, given by the complex Fe+3 - Xylenol concentration, has a temporal dependency, to which its diffusion coefficient was determined together with the activation energy, necessary for the Fe+3 migrations in the gel. These two parameters were measured, for the first time, for the Fricke Xylenol Gel and for that a novel methodology was also created. The measured parameters, dosimetric ones together with the diffusion coefficient and activation energy corroborate, to present the chemical dosimeter, as an adequate one to be used in radiotherapy with electron beams for small field sizes.

Der volle Inhalt der QuelleThis research, dealing with areas abandoned by agriculture, shows the stakes and ambiguities of the different literature developped on the topic of fallow lands and on the dangers they are supposed to entail for rural landscapes. Beyond problems of definition of these marginal lands and uncertainties about statistical results - from 2. 5 to 5. 4 millions of hectares, according to different inventories -, fallow lands are studied in their full diversity : diversity of causes, mechanisms and situations of land abandonment, diversity of the real estate statutes, diversity of thelandscapes and the ecollogical evolutions. In two areas of small and medium-sized mountains, on mediterranean margins, where fallow lands and agricultural decline have been operating for a long time (boutieres ardechoises, occidental high-languedoc), Two complementary ways of research try to point out such a diversity : the first one analyses the place of marginal lands in the farming concerns' areas and strategies, and their functions, espacially pastoral ones. Prospects of succession of the farmers, and also phenomenons of agricultural recovering of abandoned lands (quality vineyards) showing the ever possible reversibility of the processes, are particularly emphasized. The second method, closely linked to the previous one, deals with vegetation and landscape dynamics of the marginal lands, especially ex-vineyards and chestnut orchards, where anthropic influences remain strong. This work finally insists on the non-agricultural uses of the marginal lands, attempting to distinguish those abandoned for a long time from those which are going to quickly recover other functions such as reforestation, recreation, urban development. . . These new functions are sometimes sources of conflicts when they bring many social actors (animal breeders, hunters, foresters. . . ) in the same area

Der volle Inhalt der QuelleThis doctoral thesis is about plant relocation. This is a thesis of industrial organization focused on plant; we will try to demonstrate that the turbulent environment nowadays causes frequent relocation of existing plants. Therefore, these firmmust learn to master and manage the plant relocation process. In a first part of the thesis, we have tried to understand the relocation phenomenon and determine how location and relocation articulate one with the other. The second part aims at analysing the plant relocation at the firm level and answer such questions as: how to work out plant relocation, which ruptures can we identify and how to manage them?

Der volle Inhalt der QuelleThis thesis is concerned with higher cluster tilting objects in generalized higher cluster categories and tropical friezes associated with Dynkin diagrams. The generalized cluster category arising from a suitable 3-Calabi-Yau differential graded algebra was introduced by C. Amiot. It is Hom-finite, 2-Calabi-Yau and admits a canonical cluster-tilting object. In this thesis, we extend these results to the case where the initial differential graded algebra is (m+2)-Calabi-Yau for an arbitrary positive integer m. We show that its associated generalized m-cluster category is Hom-finite, (m+l)-Calabi-Yau and admits a canonical m-cluster tilting object. In this triangulated category, we obtain a class of m-cluster tilting objects by taking advantage of silting mutation and derived equivalence. For generalized m-cluster categories arising from strongly (m+2)-Calabi-Yau differential graded algebras, we prove that each almost complete m-cluster tilting P-object admits exactly m+1 complements with periodicity property. Finally, inspired by Ringel's work on cluster-additive functions on stable translation quivers, we introduce tropical friezes on 2-Calabi-Yau categories with cluster-tilting object. We show that any tropical frieze on the cluster category of a Dynkin quiver is of a special form and give a proof of a conjecture of Ringel on the form of cluster-additive functions

Der volle Inhalt der QuelleDouble trapping of neutral atoms is one of the most recent advances in the study of collisions cold. Experimentally obtained the rates of loss due to the interaction of species alkaline mixed (Cs / Rb). We use a magneto-optical trap mixed operating with beams of high intensity allowing the cooling and containment of the samples successfully. This work is so important because it represents the first step to study the process of formation of molecules heteronucleares cold. A comparison between two techniques of monitoring procedures for cargo of atoms was performed. The results both qualitatively and quantitatively were satisfactory. And the rates of loss of interest and analyze the rates considering the ratio between the masses of atoms involved and focusing on the effect caused by the difference of mass between them thus completing the main objective of this dissertation.

Der volle Inhalt der QuelleA dosimetria química tem sido utilizada como referência na medida da dose absorvida, com o dosimetro Fricke, em laboratórios de padronização. Este dosímetro é considerado um padrão dosimétrico absoluto em medidas de dose de radiação entre 20 e 400 Gy, cobrindo um amplo espectro de energia, desde raios- X, raios-g até feixe de elétrons rápidos. O presente trabalho tem como objetivos implementar o dosímetro Fricke tradicional no Centro Regional de Ciências Nucleares CRCN/CNEN e desenvolver uma metodologia para a sua utilização em raios-X de baixa energia, isto é, raios-X com energia média no intervalo de 19,7 KeV a 52,2 KeV. Esta metodologia é requerida para viabilizar uma faixa mais ampla de aplicação do dosímetro Fricke incluindo os raios-X de baixa energia utilizados no tratamento de tumores superficiais. O método proposto foi validado por meio de intercomparaçãoes com câmaras de ionização calibradas para medidas de Kerma no ar em feixes de radiação de Co-60 e raios-X de baixas energias (superficiais). Quando utilizado na dosimetria de fontes de radiação gama de altas energias, Co-60, o desempenho do dosímetro Fricke foi avaliado comparando-se os seus resultados aos obtidos com câmara de ionização cilíndricas, rastreadas ao PTB Physikalisch-Technischen Bundesanstalt e ao NPL National Physical Laboratory. Para análise da reprodutibilidade do dosímetro Fricke, utilizou-se um irradiador do tipo Gammacell, com 5 amostras de solução Fricke distribuídas simetricamente; as irradiações foram realizadas em 8 experimentos cujos tempos de irradiação foram de 6,4 até 160 segundos. As doses induzidas foram analisadas e com a avaliação estatística um desvio padrão de 1,5 % foi obtido. Para medidas da grandeza dose absorvida na água em feixes de raios-X, utilizou-se fatores de correção para a resposta do dosímetro Fricke em relação a uma câmara de ionização de placas paralelas do tipo rastreada ao PTB. Os resultados indicam que o dosímetro Fricke tradicional opera adequadamente para dosimetria de altas energias (Co-60) e para se obter uma incerteza em torno de 3% deve-se utilizar absorvâncias com valores maiores do que 0,15, o que corresponde a uma dose de aproximadamente 40Gy. Estas condições de operação do dosimetro Fricke atendem às especificações da norma ASTM E 1026-04. Para a dosimetria de raios-X superficiais, houve a necessidade de calibrar a resposta do Fricke com a câmara de ionização, pois nesta faixa de energia o dosímetro Fricke não é absoluto, devendo ser calibrado. A introdução desta etapa induziu nova incerteza que foi avaliada e calculada na incerteza total. A incerteza na dosimetria de raios-X superficiais, para doses acima de 62 Gy, com o dosímetro Fricke é em torno de 10%; neste caso, devido à correção da exatidão do Fricke em relação à câmara de ionização, uma absorvância de 0,15 corresponde no caso de pior exatidão a uma dose de 62 Gy. A sensibilidade do método dosimétrico sendo limitada pela medida no espectrofotômetro da concentração de +3Fe induzida pela radiação, leva à conclusão: o dosímetro Fricke é um instrumento adequado para a medição de raios-X superficiais em uma faixa de 42 Gy a 620 Gy

Resumo: Este trabalho busca elementos para se determinar a densidade de empacotamento de esferas definida por reticulados no plano hiperbólico.Consideramos o espaço de teichmuller Tu de todas as superfícies orientadas com-pactas e fechadas de gênero 9 2: 2, as quais tem o plano hiperbólico como recobrimento universal riemanniano. É conhecido o sistema de coordenadas Fricke em Tu que associa a cada superfície um domínio fundamental de Voronoi-Dirichlet dado por um polígono convexo com 4g arestas. Sabemos que, fixado o gênero, a densidade cresce com o número de arestas do domínio de Voronoi-Dirichlet escolhido, de modo que é natural a busca por polígonos com um número máximo de arestas associado ao gênero dado, que é sempre limitado por 12g - 6.Neste trabalho, determinamos as coordenadas Fricke em Tu que associa a cada su-perfície um domínio de Voronoi-Dirichlet com 4g + 2 e 12g - 6 arestas. Além disso, determinamos e implementamos algoritmos para a determinação dos círculos inscrito e circunscrito de um polígono (em superfícies de curvatura constante). Estes algorit-mos, em sua generalidade tem complexidade O (n4) mas, restringindo os polígonos a vizinhanças abertas de um polígono dado, possui complexidade O (n), situação ótima.A determinação dos domínios de Voronoi-Dirichlet e dos círculos inscritos permitem definir a densidade de empacotamento diretamente nos espaços de teichmuller através de um sistema de equações polinomiais
Abstract: This work searches elements to determine the packing density of spheres defined by lattices in the hyperbolic plane. We consider the teichmüller space Tg of all closed compacts oriented surfaces of genus 9 ~ 2, which has the hyperbolic plane as universal covering rienmannian surface. It is known that the system of Fricke coordinates in Tg associates each surface to a fundamental of Voronoi-Dirichlet domain, given by convex polygon with 49 edges. We know that, with fixed genus, the density increases with the number of edges of the chosen Voronoi-Dirichlet domain. Thus it is naturallooking for polygons with a maximum number of edges associated to a given genus, which is always limited by 129 - 6.In this work, we determine Fricke coordinates in Tg which associates each surface to a Voronoi-Dirichlet domain with 49 + 2 and 129 - 6 edges. Furthermore, we determine and we program the algorithms for determination of the inscribed and circumscribed circles of a polygon (in surfaces of constant curvature). These algorithms, have com-plexity O (n4) , but when restricted to open neighbourhoods of a given polygon, have complexity O (n), best situation.The determination of the Voronoi-Dirichlet domain from the inscribed circles per-mits to define the packing of density directly on teichmüller spaces through a polyno-mials of system equations

Der volle Inhalt der QuelleMarginality was first tackled especially from the 1970's and was analysed by various scientific disciplines, for instance by geography and more particularly by social geography. It was often confused and used to characterise exclusion, and it also knew a shift in meaning so that it was then regarded as subjected. However, why not define marginality as a voluntary choice which will enable the individual to become an active subject who will be shaping their own life and their surroundings. Margins, from then on, come down to laboratories for innovation and creation, thus developing an ideology, standards, and distinct values. Subjects in margin indirectly contribute to the town and territory planning as well as to the local development. Thus, relying on urban wastelands invested in France by creative movements, we aim at showing the dynamics, the process and the mechanisms thanks to which a margin can become a centre of the process of territorial reconstruction and redefinition, leading to new planning approaches and new approaches of territory planning and local development

Der volle Inhalt der QuellePAHs are present in many industrial wasteland soils. Their remediation using biological techniques remains limited because of their low availability. This work identifies some of the factors controlling this availability in soil and proposes management strategies able to modify it, focusing on plant assisted treatment. First, we have shown that PAHs availability can be estimated by a 30 hours extraction using a Tenax® resin. The analysis of PAHs availability for three wasteland soils showed that the size of black carbon particles, which is the main PAHs reservoir, and the aggregation intensity are the two main availability controlling factors. Laboratory experimentation also showed that this availability can be influenced by rhizosphere parameters. Acidification of a calcareous soil, in dissolving the carbonated cement, can increase PAHs availability by desaggregation. Soil alkalinisation, in decreasing sorption forces between PAHs and the solid matrix, may also increase availability. Citric acid has an effect even more pronounced than the pH alone. Its chelating properties can increase PAHs availability by 40%. Some of these laboratory results have been confirmed by in situ experiments. Indeed, a white lupine culture was able to increase anthracene dissipation for one of the tested wasteland soil over a 5 months period

Der volle Inhalt der QuelleIn a context of general reform of public policies and of adaptation of the tool of Defence to new geostrategical pressures, Military brownfields are growing.In the past, the city used easily the land space on its fringes. While it is today trying to rationalize the urban network in the frame of sustainable development, it is more interested in its derelict lands and it tries to set up a logic of urban regeneration which could be applied to all these wastelands, whatever is the nature of their initial activities. Among these waiting of renewal sites, the urban military wastelands could give real opportunities as part of regeneration and so participate to the urban renewal.The objective of this thesis is twofold: It is to consider how the military urban brownfields can be unmarked since their initial activity has ceased. Then, by reading the results of the regeneration with the fourth time of wastelands, it is about to determine if the regeneration of an urban military brownfields can have a leverage effect for a city or region.Five study sites are analyzed to answer these questions

Der volle Inhalt der QuelleThe nature of historical documentation in Languedoc has tended to draw the attention of ruralist historians to the heart of cultivated area and the famous trilogy of cereals, vines and olive trees. Margin, that is to say the vast amount of reputedly uncultivated land, has held little interest. However, most of these lands were indeed maintained and brought a great deal of resources to rural areas. Whether enjoyed communally or privately, they were areas cleared on a permanent or temporary basis, but they were also for grazing, food and wood gathering as well as various other purposes. On some of them grew the plant Spartium junceum L. , a marker of the human exploitation of land located at the interface between ager and saltus. The increasing maintenance of this broom growing in the Lodévois during the modern period is involved in processes of complex cropping at the borders of the cultivated area. A microhistorical approach – which opens onto neighboring regions of the Lodévois and the periods before and after – to this plant from uncultivated areas, crosses economic and social history with the history of technology, and in particular agronomy. Broom regenerated the poor soils of hills, providing textile fibers and nourishment for livestock during the winter. The exploitation of spartium, seemingly marginal, does indeed contribute in its own way to agricultural change from the eighteenth century onward

Der volle Inhalt der QuelleIn this work, we study a partial wave resonance process which allows us to increase the molecule formation rate up to six times. This was done by an atomic temperature variation which was first trapped in a magneto optical trap (MOT) by applying a molasses stage. A qualitative explanation was presented for the observed effect through the partial waves solutions for ground states interacting atoms. We loaded an optical dipole trap formed by a Ti:Sapphire laser. Finally, we discuss the importance of such results for our research and their use in future experiments.
