- Abstract
Ore preparation facilities are complex facilities and various wastes in the form of solid, liquid and gas can come out of these facilities. Generally, various chemicals can be found in the wastes that pass through the aqueous processes. According to the type of enrichment method used in the process, the contents of the wastes also change. While some wastes consist entirely of harmless natural stones, some wastes may contain harmful chemicals such as cyanide, sulfur, fatty acid, alcohol and caustic. In such cases, the treatment of waste also differs. A different waste disposal method should be followed for each mine type. In this study, the wastes from the ore preparation facilities, which are also under control with legal sanctions, and the management of wastes are discussed. [ABSTRACT FROM AUTHOR]

- Abstract
Depuis plusieurs décennies, le Québec tente de faire preuve de leadership sur la scène internationale sur les sujets du climat et de l’environnement, et ce, de manière distincte du Canada. Les orientations stratégiques adoptées par l’État québécois dans le cadre de sa politique internationale visent notamment des actions en faveur d’une transition énergétique. En ce sens, lors de la 26e Conférence des Parties à Glasgow en 2021, le Québec joint la Beyond Oil and Gas Alliance, une alliance internationale visant à mettre fin progressivement à l’utilisation des combustibles fossiles. À titre de signataire, le Québec s’est engagé à : 1) mettre fin à toutes nouvelles concessions, licences ou location destinées à la production ou à l’exploration pétrolière ou gazière, 2) mettre un terme aux subventions publiques impliquant des activités liées aux hydrocarbures 3) assurer une transition juste 4) adopter des orientations politiques claires permettant le foisonnement d’innovations technologiques et une diversification des activités économiques et, 5) soutenir les pays en développement dans l’atteinte d’une croissance verte. L’objectif de cet essai est donc d’analyser l’état de mise en œuvre de ces objectifs au Québec, et ce, par l’analyse de deux outils structurants : la Loi visant principalement à mettre fin à la recherche et à la production d’hydrocarbures ainsi qu’au financement public de ces activités – ou loi 21 - et le Plan pour une économie verte 2030. En complément, un bref regard est également porté sur le Programme de coopération climatique internationale. L’analyse de ces outils et des données disponibles permet de déterminer que le Québec progresse dans la bonne voie pour atteindre les objectifs de la Beyond Oil and Gas Alliance. Toutefois, il est possible de noter que l’application de la loi 21 et le processus de suivi des actions issues du Plan pour une économie verte 2030 comportent des lacunes. Dans le premier cas, la mise en œuvre est au statu quo due à la mu

How did the French Television cover the Iran-Iraq War (1980-1988)? What imaginary did the TV journalists refer to? Why and how has the political, economic and social context in France also interfered in reading the conflict? Based on a systematic study of the eight years of this War as shown by French TV, this article aims to analyze the shifts that have taken place, ranging from a presentation of a conventional and distant war, with its parallel with the First World War and for then, leading to the appearance of a great fear of Islam. It also aims to complete studies on the crystallization of representations of an "Islamic threat" in France in the 1980s.

Russia's geographical position is closely linked to its geopolitics, and geographical assumptions are historical determinants in the development of both society and territory. Specific assumptions are mainly the natural conditions, which applied to the location of the economy, but which also affected its mutual relations with other states. The role of natural determinism as well as Russia's position as a power controlling a crucial part of the Eurasian continent is discussed in many studies. The presented study nanalyzed the importance of primary energy sources in the interdependence of the links between Russia and the European Union; with an emphasis on the energy factor in the influence it exerts on policy, as well as the interdependence of both entities. This questions were examined by analyzing the current situation of the unchanging territorial structure of the Russian export and European import flows of fossil fuels. The current transport structure of Russian fuel and trade flows of primary energy resources from Russia to the European Union were also analyzed. The synthesis of the acquired knowledge shows the necessity for the further development of mutual relations. It also showed the need for diversification of energy of both geographical segments which were examined. [ABSTRACT FROM AUTHOR]

Energy is a life-sustaining global commodity having the quality of bringing prosperity. There is a strong mutual affinity between the availability of energy supplies and opportunities for growth, innovation, and increasing prosperity. In the last decade, the biggest change in energy was how and where hydrocarbons were removed from the earth in the lead of The United States. For instance hydraulic fracturing, or “fracking,” which allows natural gas to be collected from shale rock formations indicate that, the next decade will be about how energy already removed from the earth is moved across it while the last decade was about the energy buried in the earth and how to get it out. Recent advances show that the shale gas and solar energy promise as alternative energy sources for future. In that article, we aim to requestion energy strategies based on the future economic and geopolitical effects.

- Abstract
Considered as the heart of electrical power transmission and distribution networks, power transformers are essential part of the electricity transmission grid. Among the condition monitoring and fault diagnosis tools for these machines, dissolved gas analysis (DGA) has proven its effectiveness in their early detection and classification of faults. Up to date, many methods have been proposed in the literature for the interpretation of DGA data, classified into traditional and intelligent methods. This paper proposes a two-steps hybrid method, which uses the strengths of both methods. The approach uses the evolutionary k-means clustering algorithm based on the genetic algorithm for subset formation and subset analysis by human expertise. In the diagnostic procedure, to determine the condition of a sample, the subset to which it belongs is first identified and then the corresponding diagnostic sub-model is applied. The proposed method has been implemented with 595 DGA data, tested on 254 DGA data and validated on the International Electrotechnical Commission (IEC) TC10 database. Their performances were evaluated and compared with existing traditional, intelligent and hybrid methods. From the results obtained with the IEC TC10 database, the newly proposed approach depicts the best overall diagnosis accuracies. Indeed, the best performance is achieved with the proposed method compared to other models in the literature, with diagnostic accuracy of 98.29% compared to 88.89% of the Gouda triangle method, to 88.03% of the Hyosun Corporation gas ratio method or to 86.32% of the three ratios technique.

Dynamic nuclear polarization, or DNP, refers to the increase of the polarization of nuclear spins in condensed matter, liquid or solid, coupled with electronic spins at low relative concentration, by inducing radio or microwave transitions at frequencies close to the electronic resonance frequency in the external magnetic field. Another described method relies on indirect optical pumping methods at temperatures close to room temperature for the nuclear polarization of rare gases. The various mechanisms of DNP are described in physical terms. This is followed by a succinct description of its main applications in various domains of physics, in chemistry and in medicine.

Background: Aflatoxins are toxic and carcinogenic secondary metabolites usually produced by certain strains of the fungi such as Aspergillus flavus, Aspergillus parasiticus and rarely Aspergillus nomius. In appropriate temperature and humidity, these fungi are able to contaminate agricultural commodities and then produce aflatoxins. This study aimed to determine the total aflatoxin level in “Gaz” produced in Isfahan city, Iran. Methods: 40 Gaz samples containing 28% and 40% pistachio nuts were prepared from production units in Isfahan city and the total aflatoxin level was evaluated via enzyme-linked immunosorbent assay (ELISA). Findings: 39 samples (97.5%) were contaminated with the mean aflatoxin level of 4.11 ± 3.55 ng/g. The total aflatoxin level in 40 samples was between non-detected and 13.97 ng/g. The mean aflatoxin level was 3.53 ± 2.49 and 4.70 ± 4.40 ng/g in samples containing 28% and 40% pistachio, respectively, with no significant difference between the two groups (P = 0.82). The mean aflatoxin level was found to be lower than the maximum tolerance limit (15 ng/g) determined by the Iranian National Standards Organization but in 4 samples (10% of samples) higher than the maximum tolerance limit (10 ng/g) accepted by the European countries. Conclusion: According to the Gaz economic importance, especially exporting to the world markets, as well as dangers of aflatoxin for human health and considering it as one of the most important health indicators, definitely an extra effort is needed to warranty the hygiene and safety of this product. In addition, national standard should be promoted to the level of developed countries.

The increased number of modern livestock farming increase pollutant gas and particulate matter emissions and expanding of residential area against rural area cause to be more sensitive to these gas and particulate matter emissions from animal operations. In this study, pollutant gas dispersions from three dairy cattle barns operated in Bursa region were modelled using hourly outdoor environmental and topographic conditions. To develop dispersion models and describe dispersion problem as a quantity, pollutant gas emissions from dairy cattle operations and CALPUFF VIEW 5.8 modelling software were used. It was determined that estimated pollutant gas concentrations in five receptor points (A-E) in surrounding environment were significant levels. Furthermore pollutant gas emissions from dairy cattle barns can reach a remarkable values in an area with 2000 m diameter in surrounding environment. [ABSTRACT FROM AUTHOR]

Ish yo’li taktida, to’g’ridan-to’g’ri yuqori haroratga ega gazlar ta’sirida bo’lgan detallar (silindrlar, silindrlar kallagi, porshenlar, klapanlar) haddan tashqari qiziydi. Yonilg’ining silindrda yonishidan ajralgan issiqlikning 20=25%i dvigatel detallarining qizishiga sarflanadi. Agarda detallardan issiqlik tashqi muhitga tarqatilmasa, ya’ni dvigatel sovitilmasa, unda harakatdagi detallarning ishqalanuvchi yuzalari orasidagi moy kuyib, ishqalanishni haddan tashqari orttirib yuboradi. Ayniqsa, aluminiyli qotishmadan ishlangan porshenning qizishi va kengayishi oqibatida, uning silindr ichida qadalib qolishi xavfi ham tug’iladi. Qiziganda, dvigatel to’la quvvat hosil qila olmaydi, yonilg’i sarfi ortadi, detallari esa yetarli darajada moylanmaganligi sababli tez yeyiladi. Shu sababli dvigatelning qizigan detallaridan issiqlikni uzluksiz ravishda tashqi muhitga tarqatib turish lozim. Lekin dvigatel haddan tashqari sovitib yuborilsa ham issiqlik energiyasi bekorga sarf bo’ladi, moy quyuqlashib, ishqalanishga sarflanadigan quvvat ortadi. Undan tashqari yonuvchi aralashma to‘liq bug’lanm aydi, qisman bug’langanlari esa silindrning sovuq devorlariga urilib, yonilg’i tomchisiga aylanadi va devordagi moyni yuvib tushirib, karterdagi moyni suyultiradi. Natijada silindr-porshen guruhiga kiruvchi detallarning yoyilishi ortadi.

- Abstract
Ushbu maqolada Issiq iqlim sharoitida dizel dvigatellarni moyi kamayishini oldini olish haqida so’z boradi. Ish yo’li taktida, to’g’ridan-to’g’ri yuqori haroratga ega gazlar ta’sirida bo’lgan detallar (silindrlar, silindrlar kallagi, porshenlar, klapanlar) haddan tashqari qiziydi. Yonilg’ining silindrda yonishidan ajralgan issiqlikning 20=25%i dvigatel detallarining qizishiga sarflanadi. Agarda detallardan issiqlik tashqi muhitga tarqatilmasa, ya’ni dvigatel sovitilmasa, unda harakatdagi detallarning ishqalanuvchi yuzalari orasidagi moy kuyib, ishqalanishni haddan tashqari orttirib yuboradi. Ayniqsa, aluminiyli qotishmadan ishlangan porshenning qizishi va kengayishi oqibatida, uning silindr ichida qadalib qolishi xavfi ham tug’iladi. Qiziganda, dvigatel to’la quvvat hosil qila olmaydi, yonilg’i sarfi ortadi, detallari esa yetarli darajada moylanmaganligi sababli tez yeyiladi. Shu sababli dvigatelning qizigan detallaridan issiqlikni uzluksiz ravishda tashqi muhitga tarqatib turish lozim. Lekin dvigatel haddan tashqari sovitib yuborilsa ham issiqlik energiyasi bekorga sarf bo’ladi, moy quyuqlashib, ishqalanishga sarflanadigan quvvat ortadi. Undan tashqari yonuvchi aralashma to‘liq bug’lanm aydi, qisman bug’langanlari esa silindrning sovuq devorlariga urilib, yonilg’i tomchisiga aylanadi va devordagi moyni yuvib tushirib, karterdagi moyni suyultiradi. Natijada silindr-porshen guruhiga kiruvchi detallarning yoyilishi ortadi.

- Abstract
Au Québec, la politique énergétique 2030 lancée par le gouvernement vise des cibles ambitieuses et l’atteinte d’une véritable transition énergétique. Pour assurer son succès, beaucoup de recommandations vont dans le sens de l’utilisation d’énergies moins polluantes disponibles dans la province pour un futur faible en carbone. Toutefois, la mise en œuvre de projets d’exploitation des ressources naturelles, notamment les projets énergétiques, exige de plus en plus l’atteinte de l’acceptabilité sociale pour répondre à la montée en puissance des contestations citoyennes environnementales qui questionnent les modalités et même les fondements de ces projets, dont leur capacité à s’intégrer aux territoires. L’objectif général de cet essai est de procéder à l’analyse des facteurs d’acceptabilité sociale du projet Énergie Saguenay dans le contexte de la transition énergétique pour la construction et l’exploitation d’un complexe de liquéfaction de gaz naturel et d’un terminal d’exportation dont le promoteur est la société Gazoduc. Pour ce faire, il est nécessaire d’analyser le contexte énergétique du Canada et de la province, ensuite, l’analyse des barrières réglementaires et normatives qui nuisent à la transition énergétique et les facteurs influençant l’acceptabilité sociale des projets. Le projet Énergie Saguenay est par la suite présenté, puis analysé selon sa capacité à correspondre aux objectifs fixés dans le cadre de cette politique énergétique et les facteurs influençant son acceptabilité sociale. Ainsi, une analyse multicritère est effectuée selon la grille d’évaluation du développement durable préparée par la Chaire en éco-conseil de l’Université du Québec à Chicoutimi, et le questionnaire d’analyse des facteurs de l’acceptabilité sociale de Mathieu Champagne et Mathieu Coté-Demers. L’analyse révèle que seul l’aspect économique du projet est favorable et que tous les autres portent d’importantes carences pour favoriser l’acceptabilité sociale. De plus, le projet ne

Hazar bölgesi belirli bir coğrafi peyzaj alanına ve büyük maden rezervlerine sahip eşsiz bir su kütlesidir. SSCB'nin çöküşünden sonra denize erişimi olan ülke sayısının ikiden (SSCB ve İran) beşe (Rusya, İran, Kazakistan, Azerbaycan ve Türkmenistan) çıkmasıyla birlikte, Hazar'ın uluslararası hukuki statüsüne dair daha önceki anlaşmalar (Rusya Sosyalist Cumhuriyeti ile İran arasında 1921 ve SSCB ile İran arasında 1940) yeni devletler tarafından sorgulanmaya başlanmıştır. Hazar'ın hukuki statüsünün belirlenmesine ilişkin Hazar devletleri arasındaki anlaşmazlık, bu sorunun çözümüne engel olan birçok nedene dayanmaktadır. Çalışmada Hazar bölgesinin en son hukuki statüsünün pekiştirilmiş olduğu 20. yüzyıldaki tarihi arka planı ve 1991'den sonra ortaya çıkan yeni siyasi durumu incelenmektedir. Çalışmamızın temel konusu olan Kazakistan Cumhuriyeti'nin, ulusal çıkar, komşularla ve dünya güçleriyle iyi ilişkiler, denge ve çok yönlü politika ilkelerine dayalı dış politikası bağlamında, 1991'den itibaren Hazar bölgesi konusunda yürüttüğü diplomasi, aldığı siyasi kararlar, hukuki düzenlemelerin araştırılması neticesinde Kazakistan'ın ekonomi politikası, enerji politikası ve enerji güvenliği politikasının öncelikleri, prensipleri, araçları ve pratikteki sonuçları açıklanmaya çalışılmıştır. Aynı zamanda genel olarak bölgenin tarihsel arka planı da dikkate alınarak, söz konusu ekonomik ve siyasi çelişkinin temel aktörleri olan beş bölge ülkesinin (Azerbaycan, İran, Kazakistan, Rusya, Türkmenistan) Hazar su kütlesi konusunda uyguladıkları diplomasi ve verdikleri kararlar, giriştikleri iktisadi projelerde yaptıkları işbirlikleri de değerlendirilmiştir. Son olarak, Enerji güvenliğinin, Kazakistan devletinin ulusal güvenlik sisteminde önemli bir unsur olduğu, ülke ekonomisinin ağır payını oluşturduğu ve dış politikayı büyük ölçüde etkilediği sonucuna varılmıştır. Araştırma konusu, Kazakistan devletinin Hazar denizi enerji politikası olduğundan yola çıkarak, dış politika kavramının temel aktör sayılan devlet (Kazakistan) ile ilişkin olduğundan dolayı realist Uluslararası Ekonomi Politik teori çerçevesinde analiz edilmiştir. The Caspian region is a unique water body with a specific geographical landscape and large mineral reserves. With the increase in the number of countries with access to the sea from two (USSR and Iran) to five (Russia, Iran, Kazakhstan, Azerbaijan and Turkmenistan) after the collapse of the USSR, previous agreements on the international legal status of the Caspian (between the Russian Socialist Republic and Iran in 1921 and 1940) between the USSR and Iran began to be questioned by the new states. The disagreement between the Caspian states regarding the determination of the legal status of the Caspian is based on many reasons that prevent the solution of this problem. In the study, the historical background of the Caspian region in the 20th century, when the last legal status was consolidated, and the new political situation that emerged after 1991 are examined. In the context of the foreign policy of the Republic of Kazakhstan, which is the main subject of our study, based on national interests, good relations with neighbors and world powers, balance and multi-faceted policy principles, as a result of the diplomacy, political decisions and legal regulations it has carried out on the Caspian region since 1991, It has been tried to explain the priorities, principles, tools and practical results of the economic policy, energy policy and energy security policy of Turkey. At the same time, given the historical background of the region as a whole, the diplomacy and decisions taken by the five countries of the region (Azerbaijan, Iran, Kazakhstan, Russia, Turkmenistan), which are the main actors of the economic and political conflict under consideration, in the Caspian reservoir, and the cooperation that they did in the economic projects they embarked on were also valued. Finally, it was concluded that energy security is an important element in the national security system of the state of Kazakhstan, it constitutes a heavy share of the country's economy and greatly affects foreign policy. The research subject has been analyzed within the framework of the realist International Political Economy theory since the concept of foreign policy is related to the state (Kazakhstan), which is considered the main actor, starting from the Caspian Sea energy policy of the Kazakhstan state.

Intact human skin surface is essential for protection against infection, preservation of body fluid homeostasis and thermoregulation. Burn injury compromises the skin barrier and enables bacterial infection, hence delaying burn wound healing. This study aimed to determine the microbial profile of burn wounds, and resistance patterns of microbes with respect to the source of the injured patient's wound. Fifty wound swab samples were collected from fifty burn patients at the Korle-Bu Teaching Hospital, Accra (KBTH). Sterile swabs moistened with sterile saline were used to swab burn wounds. The swabs were plated on blood agar and MacConkey agar for 24 hrs at 37°C. Biochemical tests were carried out on the representative isolate on each plate, and antibacterial sensitivity pattern was determined using the Kirby-Bauer disc diffusion method. The study revealed that the main source of burns was gas flames (66%) and scalds (28%). Out of the 50 samples analysed, 86% were culture positive and 14% were culture negative for bacteria. The predominant organisms isolated were Pseudomonas sp. (30.2%) and Acinetobacter sp. (20.9%). Proteus mirabillis (2.3%) and Staphylococcus aureus (2.3%) were the least frequently isolated bacteria. Although Pseudomonas sp. showed varying resistance levels to gentamicin, cotrimoxazole and ciprofloxacin, all the Acinetobacter sp. were resistant to most of the tested antibiotics used. Resistant gram negative bacteria are the most common isolates associated with burn wounds in Accra, Ghana. Hence a careful selection of antibiotics to control the wound infection is required for proper management of burn wounds in order to help reduce morbidity and mortality. [ABSTRACT FROM AUTHOR]

Pour l’année 2021, la hausse des prix en France a ainsi atteint 3,4 % selon Eurostat, soit un taux inférieur à la moyenne de la zone euro, à savoir un peu plus de 5 %. Outre l’énergie, cette inflation s’explique par le redémarrage concomitant des grandes économies mondiales. Cependant, l’on peut déjà constater un début de désengorgement des chaînes de production. Cet embouteillage était en effet dû au fait que tout le monde s’était mis à consommer, des biens industriels notamment, au même moment. Il s’agit là d’un premier indice qui peut nous laisser penser, même s’il faut être prudent, que les prix, qui continuent d’augmenter en janvier 2022, pourraient se stabiliser en cours d’année, voire même baisser quelque peu en fin d’année.

- Abstract
Introduction: Fractional laser technology is a new emerging technology to improve scars, fine lines, dyspigmentation, striae and wrinkles. The technique is easy, safe to use and has been used effectively for several clinical and cosmetic indications in every skin type. Devices: Different fractional laser machines, with different wavelengths, both ablative and non-ablative, are now available in Turkey. A detailed understanding of the device and wavelenght being used is recommended. Indications: Common indications include resurfacing for acne, chickenpox and surgical scars, periorbital and perioral wrinkles, photoageing changes, facial dyschromias. The use of fractional lasers in stretch marks, melasma and other pigmentary conditions, dermatological conditions such as granuloma annulare has been reported. Laser parameters: There are different machines based on different technologies available. Choice parameters depend on the type of machine, location and type of lesion, and skin color. Physician needs to be familiar with these requirements before using the machine. Anesthesia: Fractional laser treatment can be carried out under topical anesthesia with mixture of lidocaine and prilocaine. Some machines can be used without any anesthesia or only with topical cooling or cryospray. But for maximal patient comfort, a topical anesthetic prior to the procedure is recommended. Postoperative care: Proper postoperative care is important in avoiding complications. Post-treatment edema and redness settle in a few hours to a few days. A sunscreen is mandatory, and emollients may be prescribed for the dryness and peeling that could occur. [ABSTRACT FROM AUTHOR]

Microfluidics is the manipulation of fluids in channels of micrometer or submillimeter size. One branch of microfluidics has developed particularly in recent years, digital microfluidics, which consists in the use of simple, synchronized and programmable operations to perform more complex operations on microfluidic objects. In liquid microfluidics, the manipulated objects are usually drops formed with two immiscible fluids.Four main elementary operations are used: moving the samples, immobilizing them, mixing them and separating them. These basic operations can then be combined to perform more complex operations, such as sample analysis or processing. More original operations are also possible, such as the realization of logic gates with microfluidic cards.All the advances in digital microfluidics have been achieved by using liquid microfluidic objects dispersed in a liquid phase. Previously, work with drops has been mentioned, but work with bubbles has also been published. To our knowledge, no work has been done on the manipulation of gaseous samples in a gaseous phase.The aim of this thesis is to develop a digital microfluidic platform for the manipulation of gaseous samples dispersed in continuous gaseous phases.For this purpose, silicon microcomponents have been developed in the laboratory: the micropreconcentrators. These components include a cavity filled with an adsorbent able to trap chemical compounds when cold and to release them when hot. A heating resistor engraved on the back of the concentrator allows to control its temperature.These micro-preconcentrators can be assembled in a fluidic circuit, adding pumps to create gas flows, valves to control and direct the flows, and thermal conductivity micro-sensors developed in the laboratory.With this setup, the four basic operations of digital microfluidics could be demonstrated. A more complex operation could be performed: the measurement of the piercing volume of several linear alkanes on Tenax TA, the adsorbent used in the concentrators. The results have been published in Lab on Chip1.Other more complex operations are being studied: sample separation, which is currently difficult to perform and to model, the possibility of performing chemical reactions in the gas phase (esterification) or digital preconcentration. The latter, more advanced, is based on the use of several preconcentrators for the detection of trace volatile compounds in a sample: in a first step the compound is captured and concentrated on a first preconcentrator with a flow lower than the piercing volume, and then transferred punctually, in a second step, to a second preconcentrator placed on another fluidic path; this second preconcentrator is thus not swept by the sampling flow and the volume of gas implemented in this second step is much lower than that needed for the first one. By repeating the sampling and transfer steps, it is then possible to greatly increase the preconcentration factor of this setup without risking the breakthrough of the compound. This operation has the advantage of not having to worry about the volume of the sample: the first concentrator only needs to trap the sample, even if it is not very efficient, to be able to increase the concentration factor by repeating the operations. This allows the detection of highly volatile compounds that would not be detected in a single preconcentration step.; La microfluidique consiste en la manipulation de fluides dans des canaux de taille micrométrique ou submillimétrique. Une branche de la microfluidique s’est particulièrement développée ces dernières années, la microfluidique digitale, qui consiste en l’utilisation d’opérations simples, synchronisées et programmables pour réaliser des opérations plus complexes sur des objets microfluidiques. En microfluidique liquide, les objets manipulés sont en général des gouttes formées à l’aide de deux fluides non miscibles.Quatre grandes opérations élémentaires sont employées : déplacer les échantillons, les immobiliser, les mélanger et les séparer. Ces opérations élémentaires peuvent ensuite être combinées pour réaliser des opérations plus complexes, telles que l’analyse d’échantillons ou leur traitement. Des opérations plus originales sont aussi possibles, telles que la réalisation de portes logiques avec des cartes microfluidiques.Toutes les avancées de la microfluidique digitale ont été réalisées en employant des objets microfluidiques liquides dispersés dans une phase liquide. Précédemment, les travaux sur des gouttes ont été évoqués, mais des travaux avec des bulles ont aussi été publiés. A notre connaissance aucun travail n’a concerné la manipulation d’échantillons gazeux dans une phase gazeuse.L’objet de cette thèse est de développer une plateforme microfluidique digitale pour la manipulation des échantillons gazeux dispersés dans des phases continues gazeuses.Pour cela, des microcomposants en silicium ont été développés au laboratoire : les micropréconcentrateurs. Ces composants comportent une cavité remplie par un adsorbant capable de piéger à froid les composés chimiques et de les libérer à chaud. Une résistance chauffante gravée sur la face arrière du concentrateur permet de contrôler sa température.Ces micropréconcentrateurs peuvent être assemblées dans un circuit fluidique, en y ajoutant des pompes pour créer des flux de gaz, des vannes pour contrôler et diriger les flux, et des micro-détecteurs à conductivité thermique développés au laboratoire.A l’aide de ce montage, les quatre opérations élémentaires de la microfluidique digitale ont pu être démontrées. Une opération plus complexe a pu être réalisée : la mesure du volume de perçage de plusieurs alcanes linéaires sur le Tenax TA, l’adsorbant utilisé dans les concentrateurs. Les résultats ont été publiés dans Lab on Chip1.D’autres opérations plus complexes sont en cours d’étude : la séparation d’un échantillon, pour l’instant difficile à réaliser et à modéliser, la possibilité de réaliser des réactions chimiques en ligne en phase gaz (estérification) ou la préconcentration digitale. Cette dernière, plus avancée, repose sur l’utilisation de plusieurs préconcentrateurs pour la détection de composés volatils à l’état de traces dans un échantillon: dans une première étape le composé est capté et concentré sur un premier préconcentrateur avec un flux inférieur au volume de perçage, puis transféré ponctuellement, dans une deuxième étape, vers un deuxième préconcentrateur placé sur un autre chemin fluidique ; ce second préconcentrateur n’est donc pas balayé par le flux de prélèvement et le volume de gaz mis en œuvre dans cette seconde étape est très inférieur à celui qui est nécessaire à la première. En répétant les étapes de prélèvement et de transfert, il est alors possible d’augmenter fortement le facteur de préconcentration de ce montage sans risquer le perçage du composé. Ce fonctionnement a donc l’avantage de s’affranchir du volume de perçage : il suffit que le premier concentrateur arrive à piéger l’échantillon, même peu efficacement, pour pouvoir augmenter le facteur de concentration en répétant les opérations. Ceci permet la détection de composés très volatils qui ne le seraient pas en une seule étape de préconcentration.
