Abstract:
Tazkiyah al-nafs is a method of purification of the human soul in the form of internal purification and external formation in order to suppress desires and bad habits that lead to mental health and behavioral disorders. Sufism figures have introduced the method of purification of the soul, including Sheikh Sa'id Hawwa, which further explains Imam al-Ghazali's method of purification of the soul. This article aims to highlight the contribution of this figure in this field and analyse the approach presented by Sheikh Sa'id Hawwa in the method of tazkiyah al-nafs. This study is a qualitative study with content analysis design. The results show that Sheikh Said Hawwa has highlighted the method of tazkiyah al-nafs that is able to educate the human soul to avoid mental health and behavioral disorders. This study can provide early guidance and highlights on the method of purification of the soul based on the Quran and al-sunnah

Abstract:
The purification of the soul is one of the spiritual activities of humans in the process of cleansing their souls so that life can be calm, understand the nature of truth and become good people through religious practice. Many humans feel uneasy, along with the times that continue to experience changes and trends in consumptive lifestyles. However, in the midst of a society that is undergoing changes due to situations of social change and lifestyle trends, there is a group of Muslims who are members of the Tariqat Al-Tijaniyah Cianjur community trying to live in peace. They try, understand the nature of truth and try to be good people through purification of the soul as a religious experience. The aim of this paper is to understand the technical way of cleansing the soul as a religious experience according to the followers of Thariqat Al-Tijaniyah Cianjur. The method used in this study is a qualitative method by describing the religious experience of the followers of Tariqat Al-Tijaniyah in Cianjur through words. The theory used is the theory of soul purification according to Shaykh Ahmad Al-Tijani. The findings show that the followers of Tariqat Al-Tijaniyah in Cianjur practice the syar'i tradition, often read magical texts so they feel confident in their souls and often recite certain prayers. The conclusion shows that the followers of Tariqat Al-Tijaniyah Cianjur understand that they are committing soul praise as a religious experience.

Abstract:
Man is a creature of God who was made as caliph of God on this earth. In order to become a caliph or messenger of God on this earth, people must always strive to purify themselves or their souls must be clean from all reprehensible actions. Thus, a soul that has been dirty and far from praiseworthy deeds will not reach union with the Creator. The term for the purification of the soul in the study of Sufism is Tazkiyah An-Nafs. To get closer to God, people must first purify their souls. This type of research is literature research using primary data sources and secondary data. The results of this research explain that in order to get closer to God, humans must first purify their souls through three steps, namely takhalli, tahalli and tajalli. By carrying out the three processes above, humans will achieve soul purification and unite with the Creator. Furthermore, this Tazkiyah An-Nafs can also be used as a therapy in all problems that occur in modern society. This can be seen in acts of patience, repentance, contentment and so on.

Abstract:
The path of enlightenment consists imitating of Jesus by practicing the virtues, especially the supernatural ones. The condition for this development of virtues is a some purity of heart. Man has to put his passions in order and fight with his major weaknesses. Then comes self-control, order in everyday life, deep conviction of the truths of faith, and more time to talk with the Lord during prayer. To achieve this state, a Christian must to pass a process of passive purification, which leads him into the mystical life. All imperfections must be removed. Therefore, God’s intervention is needed, which is expressed through special inspirations. Then the gifts of the Holy Spirit enable us to receive them. The Christian experiences passive purifications of senses and of spirit. This state can be compared to the purification of the senses. The purification of the soul is compared to the purification of gold in a crucible. In this state, prayer develops from meditation to emotional prayer. The Christian must therefore remove the obstacles in the development of prayer.

Abstract:
Scholars often take purification (κάθαρσις) to be a concept that persists the same throughout Plato’s dialogues. Generally, they take it to mean the separation of the soul from the body, picking up on Socrates’s account at Phaedo 67c–d. I do not find that this account of purification endures throughout the dialogues. In this paper, I argue that in Symposium Diotima describes purification differently. I argue that her account of purification emphasizes preparedness for encountering the forms, not the eradication of the corporeal. I present this account in three steps. First, I discuss Diotima’s lower and higher mysteries, focusing on the lower mysteries. Next, I examine Diotima’s use of the Eleusinian mysteries as an analogy for her own mysteries. Here, I overview the historical rites at Agrai and the Eleusinian Mysteria. I argue that, mirroring the Agrai rites, Diotima’s lower mysteries are purificatory, and therefore provide an account of purification. Finally, I explain the account of purification Diotima presents in the lower mysteries as the desire to possess the deathless deathlessly. Diotima’s account of purification is importantly distinct from the Phaedo account. In the former, the separation of the soul from the body is in no way important for purification. We must confront the discrepancies between these accounts and recognize that purification is not a doctrine that persists throughout the dialogues.

Abstract:
This paper presents Olympiodorus’ and Damascius’ explanations of the philosopher’s practice of dying in Plato’s Phaedo. It also includes a presentation of Ammonius’ exegesis of the practice of death (meletē thanatou). The Neoplatonic commentators discern two kinds of death, the bodily or physical death and the voluntary death. Olympiodorus suggests that bodily death is only an image of voluntary death and cannot be recognized as an original death, because original death presupposes the preparation for death and the constant effort for the purification of the soul during the philosopher’s life-time. Only preparation for death and purification can ensure the complete separation of the soul from the body. Relative to this distinction is that between apothnēskein and tethnanai; these infinitives denote the dual meaning of death: death as an event or a process and death as a state. Our study examines thoroughly the subtle distinctions made by Olympiodorus and Damascius and offers a comparative analysis of the two definitions of death as well as that of purification. It reaches the conclusion that apothnēskein is a necessary condition of tethnanai, i.e. of a definitive release and parting of the soul from the body. On the other hand, the process of eventual purification, a notion which betrays the religious character of purification, can be identified with apothnēskein, which is the practice of dying by the true philosopher. Finally, our study also emphasizes and explains the difference between the voluntary philosophical death and the voluntary unphilosophical suicide; the latter guaranteeing only bodily or physical death.

Abstract:
Happiness is the goal of human life throughout the world. All teachings in religion are meant to bring about a happy life. However, mental disorders have now reached 13% associated with suicide with 800,000 suicide deaths worldwide. The human soul has an important role in the success of a person to achieve his goals. According to Imam Al-Ghazali, a person will gain success in his life with a healthy and calm soul, and purify himself through remembrance of Allah SWT. This research uses descriptive and analytical methods. The aims of self-purification are (1). Taṭahhur, which is an effort to cleanse the soul of all the bad things that have been done in the past. (2). Takhallaq is an effort to adorn oneself with praiseworthy morals. While (3). Taḥaqquq is an effort to realise noble positions. The virtues of dhikr according to Imaam Al-Ghazali by doing one of them. Can get forgiveness, anticipate forgetfulness and negligence and reassure the soul. By doing dhikr through self purification, it is a means to get closer to Allah and have a sense of attachment to Allah SWT.

Abstract:
Ce travail a porté sur l'étude des mécanismes de purification du silicium par plasma inductif oxygène en présence d'un laitier fluore sous polarisation. Nous avons focalisé notre travail sur l'élimination du bore et du phosphore qui sont les deux principaux dopants du silicium. La première partie de cette étude a consisté à établir et comparer les diagrammes thermochimiques de stabilité des composés du bore et du phosphore en présence de Baf#2, Caf#2 et Mgf#2. Nous avons conclu qu'en présence de fluor et d'oxygène le bore était éliminé sous forme d'un composé volatil: bof. Nous avons pu déduire que Baf#2 est le meilleur laitier pour l'élimination du bore. Nous avons également mis en évidence la nécessité d'imposer un potentiel au matériau au cours du traitement. La seconde partie de ce travail a consisté à suivre l'élimination du bore au cours du traitement par spectroscopie d'émission en ligne. Nous avons alors pu confirmer que Baf#2 permettait l'élimination du bore la plus importante. De plus, l'imposition d'un potentiel anodique augmente l'évaporation du bore. Nous avons déduit que la polarisation anodique stabilise les espèces clés des mécanismes de purification: les anions O#2# et F#. L'efficacité du laitier fluore a également été mise en évidence dans le cas de l'élimination du phosphore. La stabilisation de l'anion O#2# permet la formation dans la goutte liquide d'oxydes volatiles du phosphore (P#4o#6, Po#2) dont l'évaporation s'ajoute a celle du phosphore gazeux. Enfin, nous avons procédé a l'étude physico-chimique du matériau après traitement. Nous avons déterminé que la présence de Baf#2 augmente la ségrégation des impuretés aux joints de grain et abaisse la viscosité de la goutte liquide, ce qui augmente la taille de l'interface plasma-bain liquide et donc l'efficacité du traitement. L'analyse du matériau après traitement (ICP, ESCA) a permis de confirmer les conclusions obtenues.

Abstract:
La biosynthese des desoxyribonucleotides, elements de base des chaines de l'adn, resulte de la reduction des ribonucleotides correspondants. Cette reaction essentielle est catalysee par une seule enzyme chez tous les organismes vivants : la ribonucleotide reductase (rnr), utilisant un mecanisme radicalaire. Actuellement, trois classes de rnrs ont ete identifiees et sont relativement bien definies. Parmi celles-ci, les rnrs de la classe i regroupent les enzymes de la plupart des eucaryotes ; elles sont composees de deux sous-unites homodimeriques r1 (#2) et r2 (#2) dont l'association permet la formation d'un complexe de type #2#2. Curieusement, la rnr des vegetaux n'a pas encore ete repertoriee. La caracterisation de la rnr des vegetaux superieurs et en particulier celle d'arabidopsis thaliana est l'objet de ce manuscrit. La sequence nucleotidique codante pour la proteine r1 a ete isolee du genome d'a. Thaliana, permettant ainsi la surexpression de cette proteine dans e. Coli et sa purification. La proteine r2 a egalement ete surexprimee et purifiee. La caracterisation de ces deux proteines a permis d'apparenter la rnr d'a. Thaliana a une enzyme de la classe i. Cette derniere est composee par un dimere de r1 et un dimere de r2. L'etude de la proteine r2 confirme, apres une etape d'activation, la presence des centres redox habituellement trouves chez les rnrs de cette classe. Il s'agit d'un radical tyrosinyle stable et d'un centre binucleaire de fer ferrique a pont oxo par chaine polypeptidique. L'association des proteines recombinantes genere le complexe fonctionnel, capable de reduire un ribonucleotide. L'enzyme est controlee par la regulation allosterique habituellement observee dans la classe i. La reduction du substrat cdp est stimulee en presence d'atp et est inhibee en presence de datp. Par contre, c'est la premiere fois qu'une activite ribonucleotide reductase vegetale est mesuree in vitro a partir d'un systeme purifie. L'interet porte a la rnr de plante est lie aux applications pratiques qui pourraient en resulter dans le domaine de l'agrochimie. En effet, cette enzyme serait une cible de choix pour la conception de nouveaux herbicides. L'obtention de cette proteine et sa caracterisation autorisent maintenant des etudes en ce sens.

Abstract:
The need for water is constantly growing, and the use of this natural resource is still not ta-ken seriously. In modern production systems, water must be of a certain quality to meet the requi-rements of its specific application. However, in recent times, there has been a growing realization that freshwater resources are finite, prompting the search for solutions that will enable reuse, thereby alleviating to some extent the problems of scarcity, cost and regulation. The use of water in industry takes a significant share of the world's water consumption, which is why this area should be given special attention. Reducing the amount of water used in various industrial branches and technical-technological processes will lead to less extraction from local water sour-ces, increased productivity, reduced discharge of waste water and its polluting impact, as well as heat energy consumption and operating costs. The reuse of wastewater in industry can be realized within one or more companies, guaranteeing them savings on water bills and treatment costs. De-pending on the pollutants they contain and the intended reuse, wastewater can either be used di-rectly or first treated and recycled. Process control is extremely important for any water tre-atment. In most cases, programmable logic controllers analyze all measured signals from the va-rious stages and control the process to ensure successful and accurate purification. Standard communication technologies (most often Profibus or Ethernet) are used to transfer this data. Mo-dern systems include solutions based on a cloud platform and automated remote control.

Abstract:
Soil contamination by polycyclic aromatic hydrocarbons (PAHs) is a widespread concern due to the high potential for human exposure through inhalation, ingestion, and dermal contact. In this study, we compared the efficiency of three different methods for PAHs extraction from model samples, including ultrasonic (US), mechanical shaking and purification with commercial QuEChERS kit (Shq), and ultrasonic extraction coupled with QuEChERS (USq) by gas chromatography coupled to a triple quadrupole tandem mass-spectrometry (GC-MS). The results showed that in the ultrasonic extraction with subsequent purification using QuEChERS, the content of PAHs in the sample varied from 86.91 to 2211.60 ng/g. Whereas, in mechanical shaking method, this range was in the range 1.56-761.20 ng/g. In the case of ultrasonic extraction without sorbent purification, only for acenaphthene, fluorene, and benzo(g,h,i)perylene, the values were higher compared to the other two methods: 285.78�27.56 ng/g, 577.48�73.62 ng/g, and 266.35�177.30 ng/g, respectively. The comparison of PAH extraction efficiency showed that the combination of ultrasonic extraction and purification with QuEChERS (USq) was the most efficient method and rapid, obtaining the highest yields for all tested PAHs.

Abstract:
The production of oil mist in machinery processing workshop is harmful. To control concentration of oil mist, the TiO2 which can treat with manifold organic pollutants is used to purify oil mist. At first, the nanometer TiO2 is prepared using the sol-gel method on the optimum formulation that showed a higher activity. Then it is treated by dip-coating technique using the non-woven fabric as composite support. The efficiency of suppression of oil mist is compared with ordinary materials. With the increase of time, the purification of the nanometer TiO2 photocatalyst sieve against oil mist of non-woven fabric is investigated in solar radiation at room temperature. It oxidizes pollutants of oil mist to CO2 and H2O. The experiments demonstrat oil mist is oxidized on the TiO2 sol at the 22nd minute with a maximum capacity of 0.3219g. It infers from the experiments the photodegradation effect is high and the reaction is fast. It also concludes that the nanometer TiO2 photocatalysis material is an ideal material for suppressing oil mist in air. At last, a status the application of technology in air purification as well as its problems and trends are presented. The technique has a promising prospect to solve the increasing air problem of the workshop.

Abstract:
Water pollution is one of the serious concerns across the world at the moment. Industrial wastewater significantly contributes to the negative impacts caused by water pollution. Textile industries discharge large amounts of effluents into water streams with little or no treatment of the discharge because wastewater treatment is an expensive process. Thus, there exists a need for a cheap and effective way to treat textile effluent that contains dyes before being discharged. A high purity silica-based Nano-adsorbent was synthesized by using rice husk as the commercially available main cheap precursor. Copper-loaded silica nanoparticles were successfully functionalized with 3-aminopropyl triethoxysilane (APTES) via the sol-gel pathway to enhance the adsorption performance of organic dyes from textile effluent. The performance of produced Nano-adsorbent was evaluated by using methylene blue as waste adsorbate. As synthesized nanomaterial was characterized by X-Ray Diffraction (XRD) and Fourier Transform Infrared (FTIR) spectroscopy, the XRD results confirmed the presence of silicon dioxide (SiO2) and paramelaconite (Cu4O3) as predicted. The FTIR confirmed the presence of Si–O stretching, N-H bending, C–H stretching, Cu–O stretching and O–H bending vibrations thereby suggesting the presence of SiO2, NH2 groups, CH2, Cu4O3 and physisorbed H2O. The optimum conditions for pH and adsorbent dosage were successfully evaluated for the adsorption process. The optimum pH at which the nanomaterial performed best was at pH 4. The optimum mass of the adsorbent that gave maximum adsorption performance was 20 mg. Kinetic studies revealed that the experimented data was in better correlation with pseudo-second-order kinetics. The outcome of this project would be of interest to textile industries looking for a cheap and effective way to treat textile wastewater.

Abstract:
Regardless of the fact that both urban ecosystems studied – Orhei and Telenești – have purification stations, they are still an essential source of surface water pollution. The aqueous soil extract (Telenești) has a pH value of 8 up to 9.8 due to the high content of calcium and potassium in the soil, due to the fact that the area under investigation has a specific character caused by the spread of solonetz-type soils, solonized chernozems, and salinated soils. The anthropogenic impact in urban ecosystems produces an imbalance in the ratio of spontaneous species and ruderal and ruderal-segetal species. The number of spontaneous species is the indicator of the degree of anthropization in urban ecosystems. Urban ecosystems have a major impact on the environment.

Abstract:
Fukushima nuclear accident of March 11, 2011, soil and water had been contaminated by radioactive cesium. Moreover, radioactive cesium was found in the ocean sludge in Tokyo Bay flowing from rivers. Cesium which is adsorbed to the sludge cannot be easily removed. One of the authors developed decomposition and purification system, a circulation-type system by fine bubbles, that is, by creating aerobic state, aerobic bacteria are activated resulting to decomposition and purification of ocean sludge. Based on the hypothesis that radioactive cesium is adsorbed on the surface of the sludge deposition. It is considered that cesium can be eluted after decomposing the deposited sludge. Once the cesium is eluted in the water, it can fix to a mineral such as zeolite. Eluting and fixing cesium adsorbed on sludge takes so much time. In this case, the concept of removing the left sludge by flocculation method and then followed by coagulating sedimentation method is studied. In this study, our objects are to show the effectivity and efficiency of using flocculation and coagulating sedimentation in removing radioactive cesium. As the results, we pointed out this method is very good.

Abstract:
The overall goal of this project was to elucidate the role of dissolved organic matter (DOM) in soil retention, bioavailability and plant uptake of silver and cerium oxide NPs. The environmental risks of manufactured nanoparticles (NPs) are attracting increasing attention from both industrial and scientific communities. These NPs have shown to be taken-up, translocated and bio- accumulated in plant edible parts. However, very little is known about the behavior of NPs in soil-plant system as affected by dissolved organic matter (DOM). Thus DOM effect on NPs behavior is critical to assessing the environmental fate and risks related to NP exposure. Carbon-based nanomaterials embedded with metal NPs demonstrate a great potential to serve as catalyst and disinfectors. Hence, synthesis of novel carbon-based nanocomposites and testing them in the environmentally relevant conditions (particularly in the DOM presence) is important for their implementation in water purification. Sorption of DOM on Ag-Ag₂S NPs, CeO₂ NPs and synthesized Ag-Fe₃O₄-carbon nanotubebifunctional composite has been studied. High DOM concentration (50mg/L) decreased the adsorptive and catalytic efficiencies of all synthesized NPs. Recyclable Ag-Fe₃O₄-carbon nanotube composite exhibited excellent catalytic and anti-bacterial action, providing complete reduction of common pollutants and inactivating gram-negative and gram-positive bacteria at environmentally relevant DOM concentrations (5-10 mg/L). Our composite material may be suitable for water purification ranging from natural to the industrial waste effluents. We also examined the role of maize (Zeamays L.)-derived root exudates (a form of DOM) and their components on the aggregation and dissolution of CuONPs in the rhizosphere. Root exudates (RE) significantly inhibited the aggregation of CuONPs regardless of ionic strength and electrolyte type. With RE, the critical coagulation concentration of CuONPs in NaCl shifted from 30 to 125 mM and the value in CaCl₂ shifted from 4 to 20 mM. This inhibition was correlated with molecular weight (MW) of RE fractions. Higher MW fraction (> 10 kDa) reduced the aggregation most. RE also significantly promoted the dissolution of CuONPs and lower MW fraction (< 3 kDa) RE mainly contributed to this process. Also, Cu accumulation in plant root tissues was significantly enhanced by RE. This study provides useful insights into the interactions between RE and CuONPs, which is of significance for the safe use of CuONPs-based antimicrobial products in agricultural production. Wheat root exudates (RE) had high reducing ability to convert Ag+ to nAg under light exposure. Photo-induced reduction of Ag+ to nAg in pristine RE was mainly attributed to the 0-3 kDa fraction. Quantification of the silver species change over time suggested that Cl⁻ played an important role in photoconversion of Ag+ to nAg through the formation and redox cycling of photoreactiveAgCl. Potential electron donors for the photoreduction of Ag+ were identified to be reducing sugars and organic acids of low MW. Meanwhile, the stabilization of the formed particles was controlled by both low (0-3 kDa) and high (>3 kDa) MW molecules. This work provides new information for the formation mechanism of metal nanoparticles mediated by RE, which may further our understanding of the biogeochemical cycling and toxicity of heavy metal ions in agricultural and environmental systems. Copper sulfide nanoparticles (CuSNPs) at 1:1 and 1:4 ratios of Cu and S were synthesized, and their respective antifungal efficacy was evaluated against the pathogenic activity of Gibberellafujikuroi(Bakanae disease) in rice (Oryza sativa). In a 2-d in vitro study, CuS decreased G. fujikuroiColony- Forming Units (CFU) compared to controls. In a greenhouse study, treating with CuSNPs at 50 mg/L at the seed stage significantly decreased disease incidence on rice while the commercial Cu-based pesticide Kocide 3000 had no impact on disease. Foliar-applied CuONPs and CuS (1:1) NPs decreased disease incidence by 30.0 and 32.5%, respectively, which outperformed CuS (1:4) NPs (15%) and Kocide 3000 (12.5%). CuS (1:4) NPs also modulated the shoot salicylic acid (SA) and Jasmonic acid (JA) production to enhance the plant defense mechanisms against G. fujikuroiinfection. These results are useful for improving the delivery efficiency of agrichemicals via nano-enabled strategies while minimizing their environmental impact, and advance our understanding of the defense mechanisms triggered by the NPs presence in plants.
