- Abstract
The chemical composition of PM10 and non-overlapping PM2.5 was studied at the summit of Mt. Chacaltaya (5380 m a.s.l., lat. −16.346950°, long. −68.128250°) providing a unique long-term record spanning from December 2011 to March 2020. The chemical composition of aerosol at the Chacaltaya Global Atmosphere Watch (GAW) site is representative of the regional background, seasonally affected by biomass burning practices and by nearby anthropogenic emissions from the metropolitan area of La Paz–El Alto. Concentration levels are clearly influenced by seasons with minima occurring during the wet season (December to March) and maxima occurring during the dry and transition seasons (April to November). Ions, total carbon (EC + OC), and saccharide interquartile ranges for concentrations are 558–1785, 384–1120, and 4.3–25.5 ng m−3 for bulk PM10 and 917–2308, 519–1175, and 3.9–24.1 ng m−3 for PM2.5, respectively, with most of the aerosol seemingly present in the PM2.5 fraction. Such concentrations are overall lower compared to other high-altitude stations around the globe but higher than Amazonian remote sites (except for OC). For PM10, there is dominance of insoluble mineral matter (33 %–56 % of the mass), organic matter (7 %–34 %), and secondary inorganic aerosol (15 %–26 %). Chemical composition profiles were identified for different origins: glucose, and for the nearby urban and rural areas; OC, EC, , K+, acetate, formate, levoglucosan, and some F− and Br− for biomass burning;

- Abstract
The chemical composition of PM10 and PM2.5 was studied at the summit of Mt. Chacaltaya (5380 masl, lat.-16.346950º, lon. -68.128250º) providing a unique long-term record spanning from December 2011 to March 2020. The chemical composition of aerosol at the Chacaltaya GAW site is representative of the regional background, seasonally affected by biomass burning practices and by nearby anthropogenic emissions from the metropolitan area of La Paz – El Alto. Concentration levels are clearly influenced by seasons with minimum occurring during the wet season (December to March) and maxima occurring during the dry and transition seasons (April to November). Ions, total carbon (EC+OC) and saccharide concentrations range between 558–1785, 384–1120 and 4.3–25.5 ng m-3 for bulk PM10 and 917–2308, 519–1175 and 3.9–24.1 ng m-3 for PM2.5, respectively. Such concentrations are overall lower compared to other high-altitude stations around the globe, but higher than Amazonian remote sites (except for OC). For PM10, there is dominance of insoluble mineral matter (33–56 % of the mass), organic matter (7–34 %) and secondary inorganic aerosol (15–26 %). Chemical composition profiles were identified for different origins: EC, NO3-, NH4+, glucose, C2O4-2 for the nearby urban and rural areas; OC, EC, NO3-, K+, acetate, formiate, levoglucosan, some F- and Br- for biomass burning; MeSO3-, Na+, Mg2+, Br- for aged marine emissions from the Pacific Ocean; arabitol, mannitol, K+ for biogenic emissions; Na+, Ca2+, Mg2+ for soil dust, and SO42-, F-, and some Cl- for volcanism. Regional biomass-burning practices influence the soluble fraction of the aerosol particularly between July and September. The organic fraction is present all year round and has both anthropogenic (biomass burning and other combustion sources) and natural (primary and secondary biogenic emissions) origins, with the OC/EC mass ratio being practically constant all year round (10.5±38.9). Peruvian volcanism dominates the SO42- concentration since 2014, though it presents a strong temporal variability due to the intermittence of the sources and seasonal changes on the transport patterns. These measurements represent some of the first long-term observations of aerosol chemical composition at a continental high-altitude site in the tropical Southern hemisphere.

La violencia que no cesa busca romper estereotipos y comprender las huellas y persistencias del conflicto armado peruano en la actualidad. A veinte años de la creación de la Comisión de la Verdad y Reconciliación, ¿cuáles fueron los usos del metarrelato de su Informe final en las reparaciones a las víctimas? ¿Cómo se manifiesta el “continuum de violencia” en los conflictos sociales actuales, las migraciones o las violencias de género? ¿En qué medida las producciones culturales interrogan la herencia de la violencia política? Abordamos estas preguntas desde una perspectiva multidisciplinaria que articula ciencias sociales, humanidades y artes.

Introducción La producción literaria peruana sobre el conflicto armado interno no es un fenómeno nuevo. Desde el principio de la década de 1980, mientras la violencia se extendía desde el sur de los Andes centrales, los autores peruanos trataron el tema, ya sea en novelas, cuentos o poemas. Así, Mark R. Cox [2008] señala una importante cantidad de obras que se han enfocado en el conflicto y sus diferentes manifestaciones desde principios de los ochenta: “Desde el 2000, que inicia el tercer p...

LALINET lidar stations were used to track down aerosols generated over Amazon region and transported over the continent. These data were merged with collocated Aeronet stations in order to help in their identification together with HYSPLIT simulations. The results show potential indication of how aerosol can age in their long transport over regions South and Westward from the source areas by change of their optical properties.

Physics ,QC1-999 - Abstract
LALINET is expanding regionally to guarantee spatial coverage over South and Central Americas. One of the network goals is to obtain a set of regional representative aerosol optical properties such as particle backscatter, extinction and lidar ratio. Given the North-South extension and influence of distinct airmass circulation patterns it is paramount to distinguish these optical parameters in order to gain better perfomance in radiation transfer models. A set of lidar ratio data is presented.

Meteorology And Climatology - Abstract
A high-performance Raman lidar operating in the UV portion of the spectrum has been used to acquire, for the first time using a single lidar, simultaneous airborne profiles of the water vapor mixing ratio, aerosol backscatter, aerosol extinction, aerosol depolarization and research mode measurements of cloud liquid water, cloud droplet radius, and number density. The Raman Airborne Spectroscopic Lidar (RASL) system was installed in a Beechcraft King Air B200 aircraft and was flown over the mid-Atlantic United States during July August 2007 at altitudes ranging between 5 and 8 km. During these flights, despite suboptimal laser performance and subaperture use of the telescope, all RASL measurement expectations were met, except that of aerosol extinction. Following the Water Vapor Validation Experiment Satellite/Sondes (WAVES_2007) field campaign in the summer of 2007, RASL was installed in a mobile trailer for groundbased use during the Measurements of Humidity and Validation Experiment (MOHAVE-II) field campaign held during October 2007 at the Jet Propulsion Laboratory s Table Mountain Facility in southern California. This ground-based configuration of the lidar hardware is called Atmospheric Lidar for Validation, Interagency Collaboration and Education (ALVICE). During theMOHAVE-II field campaign, during which only nighttime measurements were made, ALVICE demonstrated significant sensitivity to lower-stratospheric water vapor. Numerical simulation and comparisons with a cryogenic frost-point hygrometer are used to demonstrate that a system with the performance characteristics of RASL ALVICE should indeed be able to quantify water vapor well into the lower stratosphere with extended averaging from an elevated location like Table Mountain. The same design considerations that optimize Raman lidar for airborne use on a small research aircraft are, therefore, shown to yield significant dividends in the quantification of lower-stratospheric water vapor. The MOHAVE-II measurements, along with numerical simulation, were used to determine that the likely reason for the suboptimal airborne aerosol extinction performance during theWAVES_2007 campaign was amisaligned interference filter. With full laser power and a properly tuned interference filter,RASL is shown to be capable ofmeasuring themain water vapor and aerosol parameters with temporal resolutions of between 2 and 45 s and spatial resolutions ranging from 30 to 330 m from a flight altitude of 8 km with precision of generally less than 10%, providing performance that is competitive with some airborne Differential Absorption Lidar (DIAL) water vapor and High Spectral Resolution Lidar (HSRL) aerosol instruments. The use of diode-pumped laser technology would improve the performance of an airborne Raman lidar and permit additional instrumentation to be carried on board a small research aircraft. The combined airborne and ground-based measurements presented here demonstrate a level of versatility in Raman lidar that may be impossible to duplicate with any other single lidar technique.

Ser. Deus. Metafísica. Lorenz Puntel. Walter Benjamin. Markus Gabriel ,Being. God. Metaphysics. Lorenz Puntel. Walter Benjamin. Markus Gabriel - Abstract
It will be basically presented the sistematic-structural philosophy of Puntel, showing how in it God is derived from the notion of being, to posteriorly defend the idea that the being and God must not be confused. Markus Gabriel’s thesis will be used which shows the impossibility of the domain of all the domains exist and the comprehension of the fundamental ambiguity of the being in the philosophy of Walter Benjamin. According to Gabriel, the philosophy of the entire generate an ontological doubling: the totality reproduces in the interior of itself, never having the determination of the last domain. Yet Benjamin proposes that there is no absolute sense of being, but multiple ways of comprehend and combine your senses. The decision to remain in fugacity of being leads to the following definition of metaphysical: a general discourse which objective is not a determined sense of reality, but an origin of the own plurality of the senses – the being. The being, then, must be understood as a name for a facticity that, because we are finite, we can not overcome and deplete theoretically. The being, therefore, must not be confused with God. He is not the transcendent guarantor, but the concept that is imposed in every way when we want to think the world and the loved ones. Apresentaremos basicamente a metafísica sistemático-estrutural de Puntel, mostrando como nela Deus é derivado da noção de ser, para posteriormente defendermos a ideia de que ser e Deus não devem ser confundidos. Utilizaremos a tese de Markus Gabriel que mostra a impossibilidade de o domínio de todos os domínios existir e a compreensão da ambiguidade fundamental do ser na filosofia de Walter Benjamin. Segundo Gabriel, as filosofias do todo geram uma duplicação ontológica: a totalidade reproduz-se no interior de si mesma, não havendo nunca a determinação do domínio último. Já Benjamin propõe que não há um sentido absoluto de ser, mas múltiplas maneiras de compreender e combinar seus sentidos. A decisão de permanecer na fugacidade do ser leva a seguinte definição de metafísica: um discurso geral cujo objetivo não é um determinado sentido da realidade, mas a origem da própria pluralidade de sentidos - o ser. O ser, então, deve ser entendido como um nome para uma facticidade que, por sermos finitos, não conseguimos superar e esgotar teoricamente. Ser, portanto, não deve ser confun- dido com Deus. Ele não é o fiador transcendente, mas um conceito que de todo modo se impõe quando queremos pensar o mundo e os entes.

Este trabalho defende a tese de que a metaf?sica em seu sentido cl?ssico, ap?s as cr?ticas da desconstru??o, perdeu totalmente sua relev?ncia filos?fica. O principal conceito deste estudo ? o de ?desconstru??o?, desenvolvido pela primeira como ?Destruktion? por Heidegger no par?grafo V de seu Ser e tempo e depois popularizado nos escritos de Derrida sobre linguagem e metaf?sica. N?o se trata, absolutamente, de um conceito acima de controv?rsias: paira, hesitante, entre o desejo de renova??o do pensamento metaf?sico e certa concep??o profundamente discut?vel de relativismo cultural. Para os autores com os quais trabalhamos ? principalmente, Benjamin, Derrida e Rorty ? toda a metaf?sica, e n?o esse ou aquele t?pico espec?fico no interior dela, tornou-se uma atividade profundamente problem?tica e que, por isso, precisa ser reexaminada e desconstru?da. Assim eles pretenderam adentrar e transcender por completo o projeto fundamental da tradi??o metaf?sica e com isso buscaram uma forma de interpret?-la numa moldura e num registro inteiramente novo, o que significou, no final das contas, forjar um estilo de escrita te?rica inteiramente original. O que defendemos nessa tese ? que h? uma tens?o dial?tica que liga essa filosofia marginal e suas quest?es com a Grande Tradi??o, no sentido em que uma s? existe pela presen?a velada da outra e de que a for?a criativa da filosofia marginal ? a fonte perene da renova??o da filosofia oficial. ? por isso que Derrida ir? falar o tempo todo de um pensamento das margens, que Benjamin ir? falar de uma filosofia do limiar e Rorty ir? propor toda uma literaliza??o do trabalho filos?fico. Todo esse trabalho de reexame dos fundamentos da metaf?sica fez com que o equil?brio do pensamento ontol?gico pendesse perigosamente em dire??o a um discurso c?tico e ir?nico que amea?ava desalojar muitas das quest?es centrais da tradi??o. Esse trabalho que pela primeira vez veio a interrogar sobre as credenciais do pensamento ontol?gico, uma vez que certa ambiguidade fundamental conduzia sua pr?pria condi??o. Sendo assim, a fun??o da cr?tica ? metaf?sica realizada pela desconstru??o foi a de resistir a certa domina??o sem?ntica, engajando-se atrav?s tanto do discurso quando da pr?tica numa atividade menor e marginal. Esse jogo de gato e rato da desconstru??o com a metaf?sica era o embate entre uma tradi??o oficial que pretendia ser a totalidade das quest?es ontol?gicas relevantes e certos fil?sofos marginais que ironizam essas quest?es por consider?-las uma fantasia do c?rebro metaf?sico compulsivamente totalizante. A desconstru??o ? ousada na medida em que desafia um pensamento que ainda precisa de valores absolutos, fundamentos metaf?sicos e sujeitos transcendentais. Contra isso ela mobilizou a transgress?o, a multiplicidade, a ironia, o ceticismo e o riso. This project defends the thesis that the metaphysics in its classical sense, after the criticism of the deconstruction, completely lost its philosophical relevance. The main concept of this study is the ?deconstruction?, developed by the first as ?Destruktion? by Heidegger in the V paragraph of his Being and Time and later popularized in the writings of Derrida about language and metaphysics. It is not, absolutely, a concept above controversy: looms, hesitant, between the desire to renewal of metaphysical thought and certain conception deeply debatable cultural relativism. For the authors with whom we worked ? mainly, Benjamin, Derrida e Rorty -, the entire metaphysics, and not this or that specific topic in its interior, turned into a deeply problematic activity and that, therefore, needs to be reexamined and deconstructed. Thus they intended to enter and transcend completely the fundamental project of the metaphysics tradition and with this sought a way to interpret in a frame and in an entirely new record, which meant, after all, to forge an entirely original theoretical writing style. What we defend in this thesis is that there is a dialectic tension that connects this marginal philosophy and its matters with the Great Tradition, in the sense which one only exists by the veiled presence of the other and of which the creative strength of the marginal philosophy is the perennial source of renewal of the official philosophy. That is why Derrida will address all the time of a boarder thought, that Benjamin will address of a philosophy of threshold and Rorty will propose a literalization of philosophical work. All this work of reexamine of the fundamentals of metaphysics made the balance of the ontological thought leaned dangerously in direction to a skeptical and ironic discourse that threatened dislodge many of the core issues of tradition. This work that for the first time came to question the credential of ontological thought, since certain fundamental ambiguity conducted to its own condition. Therefore, the criticism function to the metaphysics held by deconstruction was to resist to a certain semantics domination, engaging through both discourse as practice in a smaller marginal activity. This mouse trap game of deconstruction with the metaphysics was the brunt between an official tradition which intended to be the totality of relevant ontological matters and certain marginal philosophers that mock these issues for considering it a fantasy of the metaphysic brain compulsively totalizing. The deconstruction is bold according as it challenges a thought which still needs absolute values, metaphysical foundation and transcendental subject. Against this it mobilized the transgression, the multiplicity, the irony, the skepticism and the laughter. Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior - CAPES

Na filosofia alem? dos ?ltimos anos se pode observar o surgimento de projetos filos?ficos que abordam a quest?o das alternativas para a Filosofia no contexto da crise do conceito de consci?ncia de si. Entre essas posi??es que nascem da crise das filosofias da subjetividade se encontra a teoria da linguagem de Walter Benjamin. Nesta disserta??o, conceito de mundo vivido pretende falar de algo que se apresenta como um ato filos?fico fundador. Ele se refere a um espa?o pr?vio e antepredicativo a partir de onde as coisas tomam seus lugares e iniciam seus movimentos na experi?ncia humana. Em Walter Benjamin essa condi??o de ser anterior do mundo ? essencialmente lingu?stico. E ? por isso que se fala de uma tradu??o desse mundo j? sempre presumido. O fil?sofo deixa claro que parte do quadro te?rico da filosofia transcendental de Kant, mas, no entanto, j? aponta para a supera??o dessa forma de pensar quando mostra que a subjetividade n?o determina o sentido do ser, mas experimenta e participa dele. Nessa nova forma de pensar se tem como central o fato de a linguagem, o sentido e a hist?ria serem o a priori com os quais o homem opera em seu mundo. Assim se passa da media??o categorial dos objetos da experi?ncia pela subjetividade para a linguagem como medial de todo conhecimento. E, portanto, o modelo da filosofia da consci?ncia deve substitu?do pelo modelo da filosofia da linguagem. Por?m, a linguagem n?o surge aqui apenas como a linguagem natural humana, mas como a inst?ncia universal de express?o de todas as coisas e, assim, coextensiva ao mundo. Ela, enquanto totalidade, aparece nos pensamentos humanos, nas suas compreens?es, nos seus desejos, nas suas paisagens e fornece o texto que o conhecimento humano procura ser a tradu??o em linguagem nomeadora. E, ent?o, a autoridade epist?mica se desloca de um sujeito que representa o mundo para uma multiplicidade de participa??es lingu?sticas de sujeitos nomeadores. Assim, na teoria de Walter Benjamin, o homem deixa de ser apenas doador do sentido e passa a ser tamb?m participador do sentido no mundo. The emergence of philosophical projects can be observed in German Philosophy in the last years, which address the issue of the alternatives to the philosophy in the context of the crisis in the concept of self-awareness . Among those positions that are born of the crisis of philosophy subjectivities is the language theory of Walter Benjamin. In this dissertation, the concept of lived world aims to talk about something that is presented as a founder philosophical act. It refers to a previous space and ante predicative from which the things take its place and start their movements in human experience. In Walter Benjamin this condition of being previous to the world is essentially linguistic. And that is why we speak of a translation of this world already always assumed. The philosopher makes it clear that part of the theoretical framework of transcendental philosophy of Kent, but, however, already points to overcome this way of thinking when it shows that the subjectivity does not determine the sense of the being, but experiments and participates in it. In this way of thinking has been central the fact of the language, the sense and the history to be the a priori with which man operate its world. Thus passes the mediation categorical of the experience objects by subjectivity to a language as medial of all knowledge. And then the model of conscious philosophy must be substituted by the model of language philosophy. However, the language does not emerge here just as the natural human language, but as the universal instance of expression of all things, and thus coextensive to the world. The language, as a totality, appears in human thoughts, in their comprehensions, in their desires, in their landscapes and provides the text that the human knowledge seeks to be the translation in nominating speech. And with this, the epistemic authority moves from a subject that represents the world for a variety of linguistic interests of subjects nominators. Thus, the theory of Walter Benjamin, the man is no longer just "donor" and the meaning becomes too "participant" in the sense of the world

ATMOSPHERIC boundary layer , *AEROSOLS , *ATMOSPHERIC layers , *TROPOSPHERIC aerosols , *BIOMASS burning , *ATMOSPHERIC composition , *AIR masses , *RAIN forests - Abstract
The Chacaltaya GAW Station (16.3505ºS, 68.1314ºW, 5240 masl) was established in December of 2011 with a set of instruments for monitoring atmospheric composition; mainly aerosol physical and chemical properties as well as concentration of greenhouse and reactive gases. The station is located on the eastern flank of the Andes Mountains near the center of South America, close to the Amazon rain forest and the highest plateau in South America, the Altiplano, at 3800 m asl. Due to its strategic location, air masses arriving from the Amazon, the Altiplano, the Pacific Ocean and the metropolitan area of La Paz/El Alto, the largest city complex in the region, are sampled regularly at the station. The daily behaviors of both aerosol and gas concentration are strongly influenced by the planetary boundary layer (PBL). A clear signal of aerosols arriving from the metropolitan area (about 1200 m below the station) is frequently measured late in the morning under the right meteorological conditions. The complex topography of the region produces complicated patterns of air mass transport and several atmospheric layers in the surrounding region. In spite of this, very different conditions characterize day and night aerosol and gas concentrations. Turbulent conditions are typically observed during daytime whereas stable conditions, characteristic of the free troposphere, are present at nighttime. However, relatively large values of aerosol concentration in the free troposphere are measured at night. In addition, long range transport of aerosols is clearly discernible in the data especially during the biomass burning season, which occurs in the transition period between the dry and wet seasons in August and September. Results from the continuous measurements at Chacaltaya and from two campaigns in the metropolitan are discussed in this work. [ABSTRACT FROM AUTHOR]
