Authors: Akhtar Parveen Shahida , Khatun Nazreena , Parveen Rahnuma , Islam Rafiqul , Ara Ferdous
Published: March 2019

Background: Malnutrition is a frequent complication in patients with advanced staged lung cancer and can negatively affect the outcome of treatments. Lack of knowledge about nutrition, complications of disease and side effects of anticancer therapies can also lead to inadequate nutrient intake and subsequent malnutrition. Nutritional status is a strong predictor of quality of life in cancer patients.

Objective: To get the effect of the nutritional intervention on outcome of dietary intake, body composition, nutritional status, functional capacity and quality of life in patients with lung cancer cachexia receiving chemotherapy.

Patients and Methods: This 6 months study included the lung cancer patients who were interviewed with clinical assessment. Nutritional score of each patient was recorded. Individualized management plan with nutritional intervention was given and nutritional counseling was done by a nutritionist every week. Chemotherapy ± radiotherapy was given. Every patient was followed up at 1st, 2nd, 3rd and 6th week and was assessed regarding symptoms, clinical findings, nutritional score and radiological status.

Results: Total 628 lung cancer patients with 523 (83%) males and 105 (17%) females (Male: female 4.98:1) were enrolled. Mean age was 56.88 years. Two thirds of them were illiterate. Around 90% came from poor and below average socioeconomic group. More than 95% male and >66% female were tobacco users in different forms. On assessing nutritional score, almost all were with high risk score (95%). About 80% presented with WHO performance status at 2 and 3. About 61% patients got treatment after hospitalization. Following nutritional intervention along with supportive, symptomatic, treatment of comorbid diseases and anti-cancer treatment, the result showed that mean nutritional score at 1st and 2nd week were 8.24 and 6.63 (high risk), at 3rd and 6th week were 5.46 and 4.34 (Intermediate risk). There was a significant effect for time (p<.001). Symptomatic improvement occurred in 60% of the patients.

Conclusion: Nutritional intervention improves nutritional score if the other treatment like supportive, symptomatic, comorbid condition and anticancer treatment could be applied adequately.

Published: March 2019

La invención de los molinos hidráulicos revolucionó el desarrollo de la humanidad, al facilitar la utilización de los recursos naturales para su alimentación. Los molinos instalados en la costa fueron una aplicación ingeniosa a las mareas; los molinos mareales constituyeron una potente industria en el litoral atlántico europeo. El molino mareal más antiguo del continente data del siglo VII d. de C., difundiéndose a lo largo de la Edad Media y durante los siglos XVII y XVIII. En el sudoeste peninsular se instalaron molinos de agua salada a partir del siglo XIII, tras su conquista a los musulmanes. En Huelva, en las marismas de las desembocaduras de sus ríos, llegaron a existir más de cincuenta. Con la llegada de la revolución industrial comenzó su lenta agonía, debida a la pérdida de rentabilidad y competitividad a lo largo de los siglos XIX y XX. Uno de los molinos mareales onubenses más singulares y de mayor envergadura fue El Pintado (Ayamonte); adquirido mediado el siglo XVIII, fue reconstruido y funcionó hasta 1946. Su historia expresa el vínculo existente entre las poblaciones costeras y el aprovechamiento de los recursos naturales, así como su vinculación con el comercio con América. La reconstrucción del molino mareal El Pintado, y su rehabilitación como centro de interpretación del patrimonio cultural y natural, como ecomuseo, ha constituido un hito en la divulgación y puesta en valor de los molinos mareales de Huelva. Actualmente, este ecomuseo constituye un equipamiento de la Red de Espacios Naturales Protegidos de Andalucía.

Authors: Sánchez Romero Margarita
Published: March 2019

Entre los días 5 y 8 de septiembre de 2018 tuvo lugar en Barcelona el 24 congreso anual de la European Association of Archaeologists (EAA). Estas reuniones suponen un lugar de encuentro y de debate en una disciplina que cada vez trabaja más en redes y conoce menos fronteras, donde la movilidad de las y los profesionales y la colaboración (o al menos el conocimiento mutuo) entre equipos de investigación está cada día más asentada como práctica; con la certeza de que, sin esos vínculos, es mucho más complicado enfrentarse a los retos, tanto científicos como sociales, de la práctica arqueológica.

Authors: Crespo Solana Ana M.
Published: March 2019

ForSEAdiscovery es un proyecto fuertemente interdisciplinar que relaciona la historia marítima de la Edad Moderna y la arqueología subacuática con las Ciencias de la Información Geográfica (SIG), con la Dendrocronología, así como con diversas técnicas analíticas sobre la procedencia de la madera, especialmente la datación por radiocarbono. Es el primer proyecto financiado por el programa Marie Curie de la Unión Europea (Programa PEOPLE) orientado a la investigación histórica-arqueológica de pecios ibéricos. Durante sus cuatro años de desarrollo primigenio el proyecto ha logrado situar el estudio histórico-arqueológico de la historia marítima en el centro de un discurso teórico-técnico que abre nuevas líneas de investigación interdisciplinar y sobre todo en la generación de new data. Es así un proyecto holístico que se espera sea continuado por una amplia red de discípulos, científicos y colaboradores de diversas disciplinas.
Función simbólica del patrimonio
Authors: Cobo Gómez Asunción
Published: March 2019

Abordar desde una perspectiva imparcial el tema de “la memoria histórica” e íntimamente ligada a ella su patrimonio implica hacer un ejercicio de humildad, solidaridad, perdón, acogimiento e inmersión en los sentimientos del “otro”. Desde que años atrás se elaboró la llamada Ley de memoria histórica, ésta ha permanecido semi dormida hasta la llegada, en mi opinión, de algunas fuerzas políticas que han aflorado en la escena pública en los últimos tiempos y han reavivado el debate. Evidentemente se ha comenzado por el elemento más representativo de la Guerra Civil, el Valle de los Caídos, un bien patrimonial distintivo de los que “ganaron” la guerra, si es que en una guerra gana alguien.
La memoria histórica y su dimensión política, social y académica
Authors: Velasco Mesa Custodio
Published: March 2019

Tres grandes vertientes convergen en el debate internacional acerca de la memoria histórica. En primer lugar se halla la estructural dimensión política inherente a la historia y, por derivación, a toda tentativa de poner de relieve un discurso contrahegemónico de la historia. En segundo lugar, las polémicas acerca de la memoria tienen, asimismo, una inmediata y elemental dimensión humana y social, por cuanto afectan, en el presente, a sentimientos íntimos de víctimas, que se han organizado para llevar a cabo sus reclamaciones. En tercer lugar, las controversias acerca de la memoria incumben de lleno a los historiadores, afectan a la propia epistemología de la historia y, en esa medida, tienen una dimensión académica. A este respecto, se distinguen dos posturas antagónicas: la de historiadores que consideran que la memoria no es asunto de la historia ni, por consiguiente, de la atención del historiador, y la de quienes reivindican su opuesto. En este artículo se abordan estas tres vertientes del debate, desde el convencimiento de que es necesario delimitarlas y tenerlas en consideración, no solo para una adecuada comprensión del fenómeno, sino también para intentar encontrar vías que mitiguen, desde premisas democráticas, las tensiones y conflictos generados al respecto.
Implementation of Sobel Method Based Edge Detection for Flower Image Segmentation
Authors: Asmaidi Asmaidi , Putra Darma Setiawan , Risky Muharratul Mina , R Fitria Ulfa
Published: March 2019

Edge detection is the first step to cover information in the image. The edges characterize the boundaries of objects and therefore edges are useful for the process of segmentation and identification in the image. The purpose of edge detection is to increase the appearance of the boundary line of the object in the image. The sobel method is a method that uses two kernels measuring 3x3 pixels for gradient calculations so that the estimate gradient is right in the middle of the window. Digital image processing aims to manipulate image data and analyze an image with the help of a computer. Matlab is made to facilitate the use of two collections of subroutines in the fortran library, linpack and eispack, in handling matrix computing, and develops into an interactive system as a programming language. Experimental results from the input image research, namely the flower image have different MSE values because each input image has a different pixel value

Authors: Desmulyati Desmulyati , Perdana Putra Muhammad Rizki
Published: March 2019

One of the providers of cloud computing services is the Google Cloud Platform developed by Google LLC. PT Lintas Data Indonesia as a vendor and distributor of technology devices is in dire need of a web server for the publicity of its products. At present, PT Lintas Data Indonesia's web server system still uses the services of hostgator hosting providers with packages with limited resources and also cannot implement system load balances and fail over on the current server system, in terms of latency access speed when pinging web servers in HostGator is quite high up to 200Ms. To improve the performance of a web server so that a load balance and fail over system can be implemented, migrating to the Google Cloud Platform environment is a solution that is expected to be able to handle existing problems. The advantages of Google Cloud Platform are servers that are rented for web servers in the form of Virtual Private Servers (VPS) so that they are easy to maintain and if you want to upgrade services. The addition of three web servers in the cluster with HAProxy server makes PT Lintas Data Indonesia's web server service more reliable in handling requests, load balances with round robin methods and fail over web servers and with HAProxy it is proven that it can increase up to 150% in handling latency issues previously it was around 30Ms.

Authors: Akmaludin Akmaludin , Badrul Mohammad
Published: March 2019

Today's communication is very important to do, this can be done by using communication tools that are currently being used by everyone, none other than SmartPhone, so people are competing to get it. Many found difficulties in choosing a SmartPhone Brand Product that suits the wishes of each user from a number of alternatives such as Advance, Xiaomi, OPPO, SAMSUNG, and VIVO, because many criteria must be considered such as memory capacity, battery durability, sharpness of capture camera, the form of design producy, the number of features produced from the product, which is equally important is the overall performance of the product. This difficulty is a general matter discussed by each user, because it requires the best solution that can be used to solve the problem. One method that can be used to select the right SmartPhone is the Analytic Hierarchy Process (AHP) method combined with the TOPSIS method. In this case AHP is used to determine the preference quantity in weighting and TOPSIS is used for mathematical detailed calculations of a number of criteria specified in ranking from a number of alternatives. The results obtained based on the mathematical calculation process are the first rank brand products with the highest weight of 0.597 from SAMSUNG, followed by a weight of 0.586 from OPPO, then weighing 0.555 from Advance, then weighing 0.511 from VIVO, and the smallest weight 0.491 from Xiaomi.

Published: March 2019

Indonesian Batik has a variety of styles. Coloring techniques affect the color quality of batik. Color is very important to show staining breakthroughs. The colors R (Red) G (Green) and B (Blue) have a close color correlation level so that it is difficult to segment. Segmentation is the process of partitioning digital images into several segments. The segmentation process is carried out on 15 batik sample data. The first step, each sample is converted from RGB - XYZ - Lab color. The average ratio of Red, Green and Blue on the RGB color and XYZ color 1:10. Segmentation using L*a*b color, displays the composition of the sample data colors into six clusters: background, yellow, magenta, purple, red and green using the clustering method. This proposed work L*a*b color space is selected which is a homogeneous space for visual perception.
Reflection of the Problems of Ukrainian Church Singing in the Source
Materials of Galicia at the End of the XIX – early XX Century
Authors: Guralna Svitlana
Published: March 2019

As a result of the awareness of the important role of spiritual and cultural
phenomena in the development of Ukrainian culture, modern society has a particular interest in the historical context of the formation of sacred art. Therefore, the process of research of church singing based on reliable information, fixed in Galician periodicals since the appearance of the first publications on this topic and before the Second World War, became the basis of the writing of the article.
The choice of methodological principles is conditioned by the specifics of
the research carried out, in particular, the accumulation of materials with
further understanding and selection. Historical and cultural studies, art
studies, theological and teaching materials, which are found at the time
periodical, preserved in the department of ukrainian, in the scientific
department of periodicals by Maryana and Ivanni Kotsiv, National Library of Ukraine the name of V. Stefanyk, and in the State Archives of the Ternopil region. The use of comparative and cultural methods helped to highlight the historically determined features of ritual and church-musical life of Galicia at the end of the 19th and the first half of the twentieth century under the conditions of expansion of the pro-government structures. Due to the functional approach, the problems of coexistence of denominations, social conditions of the Greek Catholic Church, the status of daco-regent education and publishing, and the role of personalities in the practice of church singing are outlined. On this basis, a holistic evaluation of spiritual and choral performance and the social context of church singing as a form of realization of the liturgical art of the Eastern rite in Galicia at the end of the nineteenth and first half of the twentieth century was achieved.
The source materials revealed the activation of public opinion in the press at that time, showed the significant role of the Ukrainian Church in
shaping national self-awareness and dominance of the spiritual factor in the outlook and everyday life of the Galician.
German Studies of Koreans in Manchuria: Gustav Fochler-Hauke and the Influence of Karl Haushofer’s National Socialist Geopolitics
Authors: Cathcart Adam , Winstanley-Chesters Robert
Published: March 2019

This article analyses scholarship and memoir writing by German geographer Gustav Fochler-Hauke with respect to Korean settlement in Manchuria, and along the Tumen and Yalu/Amnok rivers in the 1930s and early 40s. The research note demonstrates that while Focher-Hauke’s work has its value—not least due to the access he received thanks to the Japanese military government—his concepts of geopolitics and the influence of his mentor and collaborator, Karl Haushofer, renders the work flawed; its value as a historical source for scholars today is therefore limited. The research note begins with Fochler-Hauke’s rising profile within German geopolitical studies and turns toward that field’s documentation of Koreans in Manchuria, the role of borders between Korea and Manchuria, the blind eye turned toward Korean resistance to Japan, and the rehabilitation of some of these scholars and works after World War II.

The Yellow Peril as a Travelling Discourse: A Comparative Study of Wang Lixiong's China Tidal Wave
Authors: Shi Flair Donglai
Published: March 2019

Joining recent scholarly efforts to free the study of the Yellow Peril from the conventional framework of Asian American and postcolonial studies, this paper offers a comparative analysis of the manifestations of this mutable racial discourse in twentieth-century Anglophone and Sinophone literatures. As a case in point, I focus on the Chinese dissident writer Wang Lixiong and his ‘racist’ appropriation of the Yellow Peril ideology in fin-de-siècle Anglo-American popular writings. By juxtaposing his canonical work China Tidal Wave, known in Chinese as Huang Huo (‘Yellow Peril’), with the Asian invasion fictions by Jack London and M. P. Shiel, I argue that instead of some kind of indisputable metaphysical truth, the Yellow Peril ideology manifested in these texts is merely a performative cultural practice that shifts its functions and allegiances according to the situated socio-political agenda of its practitioner. This performative nature is made explicit through my analyses of the changes of their paratexts as these texts travel across languages, leading to further reflections on theoretical concepts such as Occidentalism, the postcolonial palimpsest, Sinophone literature, and world literature.
Obstructive Sleep Apnea is Associated with Longitudinal Increases in Amyloid Burden in Elderly Mild Cognitive Impairment Individuals

Published: March 2019

Cross sectional analysis has shown an association between Obstructive Sleep Apnea (OSA) severity and Aβ burden using amyloid-PET among Mild Cognitive Impairment (MCI) patients. However, whether OSA accelerates longitudinal increases in amyloid beta (Aβ) burden in MCI patients is presently unclear. Study participants included a total of 798 subjects with a diagnosis of MCI and were a subset of the ADNI cohort (adni.loni.usc.edu). OSA was self-reported and participants were labeled either as OSA+ or OSA−. Aβ burden was determined by florbetapir SUVRs. To test whether OSA is associated with the rate of change in Aβ data longitudinally, multilevel mixed effects linear regression was used to fit the models with randomly varying intercepts and slopes allowing dependence on OSA status. The final model was adjusted for age, sex, body mass index, education, CPAP use status, history of respiratory disease, hypertension, diabetes, and history of cardiovascular disease. A significant variation in the change (slope) in Aβ volumes over time was seen (p<.0001). The covariance between the baseline Aβ level and Aβ volume change over time indicated that OSA subjects experienced greater mean change differences in brain Aβ volumes over time (p < .0001). The rate of change in Aβ deposition also varied significantly across OSA groups over the follow-up period. Obstructive Sleep Apnea possibly facilitates longitudinal increases in amyloid burden in elderly Mild Cognitive Impairment individuals. Further research examining mechanisms underlying effects of OSA on the longitudinal increases in Aβ burden is needed.

Experiencias agroecológicas para el mejoramiento de suelos en el huerto orgánico de la UIDE, campus matriz
Authors: Terneus Esteban
Published: March 2019

En la agricultura libre de agrotóxicos los microbios, minerales y materia orgánica (“Las Tres Ms”) son esenciales para lograr un huerto productivo. Con el fin de crear un espacio para evaluar el potencial de este concepto, se creó en la UIDE una huerta que funciona bajo los principios de la agricultura orgánica. Ante la deficiencia de nutrientes en el cultivo, se planteó su manejo mediante técnicas agroecológicas. Para ello se recolectó materia orgánica abundante (una mezcla de viruta y majada de caballo) para incorporarla al suelo. Un sustrato que presenta retos importantes por su contenido alto de carbono y que, aparentemente, inmoviliza el nitrógeno presente. Nuestro trabajo comprende diversos ensayos que incluyen el uso de minerales presentes en el polvo de roca. Materiales que la agricultura convencional no los considera esenciales. Presentamos aquí resultados de diversos experimentos con sustratos para germinación, vermicompost, bocashi. mulch orgánico, microorganismos de montaña y microorganismos efectivos activados (EMAs) dirigidos a mejorar la disponibilidad de nutrientes. Los resultados obtenidos evidenciaron que la alfalfa y el césped, usados como mulch (18 kg/m2), tienen potencial como fuentes rápidas y efectivas de nutrientes. Además, el polvo de roca (0.85 g/ml) y el hueso molido (concentraciones iguales o inferiores a 0.011 g/ml) podrían ser útiles para optimizar sustratos para germinación.

Published: March 2019

Healthy riverine systems provide ecological services that can be translated into human use and consumption. However, human activities cause environmental degradation limiting available pristine water supply and raising public health concerns. In the present study, four tributaries surrounding Mt. Matutum Protected Landscape (MMPL) were selected (Glandang, Linan, Kawit, and Amlok) for evaluation of their physicochemical and microbial characteristics between wet and dry season. The pH and total dissolved solids (TDS) of the river waters ranged from 6.75-8.68 and 55.96-221.89 ppm, respectively, with a pronounced pH fluctuation and TDS increase in Glandang and Linan tributaries from upstream to downstream stations. All tributaries showed varying dissolved oxygen (DO) levels upstream but become relatively stable downstream. All DO values, however, are below the standard limit set for freshwater quality. In terms of microbial load, total coliform ranged from 51-275 cfu/ml while E. coli showed absence (0 cfu/ml) to as high as 77 cfu/ml. Higher total coliform counts were observed on Kawit and Amlok tributaries which are situated in areas that are relatively more forested than the other two rivers. Presence of E. coli was also detected in the water samples from all tributaries. Temporal variation is significant indicating increased pH, TDS and microbial load during the wet season and DO during the dry season. The present microbial load of the four tributaries would restrict the utilization of water resource and necessitate proper treatments prior to domestic use.

Radiographic Calibration With a Prosthetic Femoral Head Allows Accurate Preoperative Templating for Total Hip Arthroplasty
Authors: Pachter Cole S. , Garfinkel Jonathan H. , Romness David W. , Gladnick Brian P.
Published: March 2019

Templating for total hip arthroplasty requires proper radiographic calibration. One option for radiograph calibration is using a cobalt-chrome femoral head ball. The authors reviewed radiographs and clinical data for patients undergoing primary total hip arthroplasty. Radiographs were calibrated using a 28-mm cobalt-chrome femoral head ball. Agreements between templated and actual implant size were calculated. The templated acetabulum matched within one size of the actual acetabulum in 76.7% to 80.0% of cases. The templated femur matched within one size of the actual femur in 83.3% to 93.3% of cases. This technique is an attractive option when a standardized calibration marker is unavailable. [

On Heckits, LATE, and Numerical Equivalence
Authors: Kline Patrick , Walters Christopher R.
Published: March 2019

Structural econometric methods are often criticized for being sensitive to functional form assumptions. We study parametric estimators of the local average treatment effect (LATE) derived from a widely used class of latent threshold crossing models and show they yield LATE estimates algebraically equivalent to the instrumental variables (IV) estimator. Our leading example is Heckman's (1979) two‐step (“Heckit”) control function estimator which, with two‐sided non‐compliance, can be used to compute estimates of a variety of causal parameters. Equivalence with IV is established for a semiparametric family of control function estimators and shown to hold at interior solutions for a class of maximum likelihood estimators. Our results suggest differences between structural and IV estimates often stem from disagreements about the target parameter rather than from functional form assumptions per se. In cases where equivalence fails, reporting structural estimates of LATE alongside IV provides a simple means of assessing the credibility of structural extrapolation exercises.
Measurable Selection for Purely Atomic Games
Authors: Hellman Ziv , Levy Yehuda John
Published: March 2019

A general selection theorem is presented constructing a measurable mapping from a state space to a parameter space under the assumption that the state space can be decomposed as a collection of countable equivalence classes under a smooth equivalence relation. It is then shown how this selection theorem can be used as a general purpose tool for proving the existence of measurable equilibria in broad classes of several branches of games when an appropriate smoothness condition holds, including Bayesian games with atomic knowledge spaces, stochastic games with countable orbits, and graphical games of countable degree—examples of a subclass of games with uncountable state spaces that we term purely atomic games. Applications to repeated games with symmetric incomplete information and acceptable bets are also presented.
The Interval Structure of Optimal Disclosure
Authors: Guo Yingni , Shmaya Eran
Published: March 2019

A sender persuades a receiver to accept a project by disclosing information about a payoff‐relevant quality. The receiver has private information about the quality, referred to as his type. We show that the sender‐optimal mechanism takes the form of nested intervals: each type accepts on an interval of qualities and a more optimistic type's interval contains a less optimistic type's interval. This nested‐interval structure offers a simple algorithm to solve for the optimal disclosure and connects our problem to the monopoly screening problem. The mechanism is optimal even if the sender conditions the disclosure mechanism on the receiver's reported type.

Comúnmente y a valores de pH inferiores a 5-6, este elemento esta presente en los medios acuosos como catión Pb2+. En el presente trabajo se investiga la eliminación de este catión de disoluciones acuosas empleando la tecnología de cambio iónico con la resina Amberlite IR-120. Se consideran una serie de variables que pueden afectar al proceso de carga del metal en la resina: velocidad de agitación del sistema, temperatura, dosificación de la resina y tamaño de partícula de la misma y pH del medio acuoso. La carga del metal responde a la isoterma de Freundlich, siendo el proceso endotérmico y no espontáneo, el mecanismo de carga no depende del tamaño de partícula de la resina y responde a un mecanismo por difusión en el medio acuoso. La eliminación del plomo(II) de disoluciones acuosas mediante la resina compite de forma favorable con respecto a los resultados obtenidos cuando se emplean nanotubos de carbono de pared múltiple como adsorbentes del Pb2+. En ensayos llevado a cabo con disoluciones binarias, la carga del Pb2+ en la resina también compite favorablemente con respecto a la de otros metales base en forma catiónica. La elución del plomo(II) se puede llevar a cabo de forma casi cuantitativa con disoluciones de HCl y distintas condiciones experimentales.

Shallow coastal areas are ecosystems with high productivity. Although the eastern part of the Mediterranean Sea is oligotrophic, the shallow coastal waters of the northern Aegean, such as Kavala Gulf, are productive due to the influence of the Black Sea water and the presence of freshwater input from three rivers. The aim of this work was to determine the structure of zooplankton communities in Kavala Gulf in the summer of 2002 and 2003 and to investigate their relation to environmental variables. Zooplankton communities were characterized by the presence of common coastal Cladocera, such as Penilia avirostris, small pelagic Copepoda, such as the calanoida Acartia clausi and the cyclopoida Oithona plumifera, and Tunicata, such as Oikopleura, Fritillaria and Doliolidae. The abundances corresponded to the peak of the warm period and were significantly greater in 2002 because of a P. avirostris bloom, which seemed to have better exploited the environmental sources favouring its dominance in the area. Overall, the structure of summer mesozooplankton communities in Kavala Gulf follows the pattern exhibited by mesozooplankton communities in other Greek coastal areas of the northern Aegean Sea.

The Río de la Plata is a large, shallow estuary located at approximately 35°S and flowing into the southwestern Atlantic Ocean. It carries a high amount of nutrients and suspended particulate matter, both organic and inorganic, to the adjacent shelf waters and is considered among the most turbid estuarine systems in the world. Knowledge of the concentration and spatial and temporal variability of these materials is critical for any biological study in the Río de la Plata. In this work, the relationship between suspended particulate matter and turbidity is empirically established in order to derive suspended particulate matter maps from satellite data (MODIS-Aqua) for the Río de la Plata region. A strong correlation between suspended particulate matter and turbidity was found (Pearson correlation coefficient =0.91) and the linear regression (slope =0.76 and intercepts =12.78, R2=0.83) explained 83% of the variance. The validation of the empirical algorithm, using co-located and coincident satellite and in situ measurements, showed good results with a low mean absolute error (14.60%) and a small and positive bias (3.04%), indicating that the estimated suspended particulate matter values tend to slightly overestimate the field values.
Iconoclasme, histoire de l’art et valeurs
Authors: Gamboni Dario
Published: March 2019

Constatant l’abondance des études sur les phénomènes de destruction, cet essai commence par analyser la situation historiographique du début des années 1980. Au point de vue normatif de l’Histoire du vandalisme de Louis Réau, dénonçant « les crimes de lèse-beauté », répondait l’Ulmer Verein für Kunstwissenschaft, qui mettait en cause l’autonomie de l’art et cherchait à comprendre pourquoi la réflexion critique se voyait taxer d’« iconoclasme ». L’essai passe en revue les directions de recherche qui ont profité de cette ouverture et les publications résultantes, mettant en évidence leurs points communs (« agentivité » des objets) et leurs liens avec l’actualité (destruction des monuments de l’époque communiste, iconoclasme islamiste, « iconoclasme » dans l’art contemporain). Il montre enfin que la valeur de la destruction dans l’« économie de l’attention » rend illusoire toute volonté de « neutralité axiologique » et appelle à une conscience réflexive accrue de la part de l’histoire de l’art.
Mutiler, tuer, désactiver les images en Égypte pharaonique
Authors: Connor Simon
Published: March 2019

Les antiquités égyptiennes qui nous sont parvenues sont souvent sévèrement mutilées. Si des causes naturelles et accidentelles peuvent être à l’origine des dommages, les images portent dans de très nombreux cas des traces évidentes de dégradation intentionnelle. À l’époque pharaonique, les images sont considérées comme puissantes et significatives, actives en tant que substituts de l’être représenté. Elles sont soignées, servent à des rites, connaissent des déplacements, sont parfois transformées et, dans beaucoup de cas, mutilées ou brisées. Pendant la période chrétienne, on les considère comme des reliques du paganisme et, en tant que telles, elles sont l’objet de vandalisme. Les contextes pharaoniques témoignent également de plusieurs phases de mutilation des images. Plusieurs causes peuvent avoir entraîné cette pratique : damnatio memoriae, pillages, dommages causés par la guerre, mais parfois aussi des raisons plus pratiques, comme la réutilisation de matériaux. Dans beaucoup de situations, comme peut-être dans le cas des « cachettes », dans lesquelles les images sont enterrées sous le pavement d’une cour du temple, la dégradation des supports du culte peut avoir été un moyen de priver l’objet de ses facultés lorsqu’il était extrait de son contexte architectural et rituel. La mutilation serait alors un moyen de « désactiver » l’image avant de l’enterrer et de la protéger magiquement.
Entre monumentum et abolitio : le rôle des images et de leur destruction dans l’art romain
Authors: Galinier Martin
Published: March 2019

Détruire un monument ou une image est, dans l’Antiquité romaine, un phénomène qui comporte deux aspects : l’abolitio memoriae à proprement parler, qui consiste à éradiquer tout signe de l’individu condamné et à laisser visible cette absence, et son contraire, la memoria des actes et du visage (imago) du grand homme, signes visibles de celui qui est considéré comme un exemple à suivre.Le destin des cités (Carthage, Corinthe, Troie) et celui des hommes sont intimement liés dans la culture romaine : les exemples civiques et familiaux, domestiques et funéraires, mettent en exergue l’obligation de se conformer à la pietas, sous peine d’éradication. Les destructions ont en conséquence une valeur morale, éducative, et elles se doivent d’être spectaculaires pour atteindre cet objectif.
Détruire, reconstruire, redéfinir : la fragmentation volontaire de la Santa Casa de Loreto et ses altérations répliquées
Authors: Giffin Erin
Published: March 2019

En tant qu’elle est le lieu de l’Annonciation, la Santa Casa de Loreto fait écho au passé, devenant une puissante destination de pèlerinage dans l’Europe catholique. Pourtant, cette construction nazaréenne ne reçoit aucune dévotion en Terre sainte. La Santa Casa s’établit d’abord dans la ville de Lorette, à l’Est de l’Italie – vers laquelle l’édifice aurait volé au xiiie siècle –, mais aussi dans les nombreuses copies de l’édifice qui occupent des nefs d’églises, des chapelles et des cloitres à travers l’Europe. Des signes d’une communion tactile apparaissent dans nombre de ces Sante Case, aux briques et aux pierres minutieusement inégales, dont les surfaces peintes à fresque s’effritent délibérément. Chaque Sainte Maison transmet effectivement la structure contemporaine au sein de nouvelles communautés, « rejouant » la dévotion à travers les actes d’une fragmentation perpétuelle qui renforcent l’adoration lorettienne.
Perdre son époque. La destruction des statues parisiennes et leur conservation au moyen de la photographie. Une relation dialectique ?
Authors: Pittnauer Beate
Published: March 2019

Entre 1940 et 1944, dans la France occupée, plus d’un millier de monuments et de sculptures ont été retirés de l’espace public puis fondus afin de servir à l’industrie de l’armement allemande. La perte du patrimoine national s’avère être une question politique épineuse, qui a suscité différentes interprétations dans le débat public de l’époque comme dans l’historiographie. Dans cette perspective, le livre d’artiste La mort et les statues (1946), publié par Jean Cocteau et Pierre Jahan, représente un document d’époque unique, qui aborde l’« autre » côté de la destruction comme une perte sans précédent, absolue. Il s’agit ici d’analyser le rôle endossé par le médium photographique dans un commentaire historique au ton personnel, et la façon dont il fait parler l’« invisible » de la destruction.

Physical and mental health are very closely tied and either of them can exert a significant effect on the other. The aim of the present study was to examine the effects of aerobic exercise training on mental health and self-esteem of type 2 diabetes mellitus patients. 60 participants, aged 40 to 55 years, with blood sugar ranging between 150 to 250 mg/dL participated in the study. They were randomly divided into two groups of 30 patients. The interventional group exercised for twelve weeks, three sessions per week, lasting from 45 to 60 minutes, followed by endurance training on treadmill. Training’s intensity was considered equal to 60-70% of maximum oxygen consumption. According to the results of the study, 12-week aerobic exercise training had significant effects on self-esteem (P=0.001), and mental health (P=0.020), sub-scales of physical symptoms (P=0.001), and anxiety and insomnia (P=0.044). But it had no significant effects on the subscales of depression (P=0.078) and social functioning (P=0.207). Regular aerobic exercise training as an effective strategy plays an important role in improving self-esteem and mental health and also promoting life quality among diabetic patients.
