El indicador condición de copa se usa para estimar la proporción de árboles con alta muerte regresiva o densidad de copa que se considere inferior o distinta a la forma natural del árbol. Las copas grandes y densas se relacionan con tasas de crecimiento altas, mientras que copas pequeñas y escasas indican sitios con condiciones desfavorables para el desarrollo de las especies forestales. Este indicador proporcionó información confiable para diagnosticar el estado general de salud del arbolado urbano. Los sitios elegidos fueron parques dentro del Distrito Federal conocidos como Alamedas Oriente, Norte y Sur. Durante la época de lluvias (mayo a octubre de 201) se realizaron tres muestreos y uno durante la época seca (noviembre de 201 a abril de 2012). Las variables registradas fueron densidad de copa (dnc), transparencia de follaje (trpf) y muerte regresiva (mr) en incrementos porcentuales (5 %) de 0 a 100. Se elaboraron pruebas de normalidad, análisis de varianza y pruebas no paramétricas U de Mann-Whitney y Kruskal-Wallis. Los resultados de estas últimas pruebas estadísticas indicaron que el arbolado de Alameda Oriente presentó los valores más altos de densidad de copa y los valores más bajos de muerte regresiva, lo que sugiere un buen estado general de salud. En contraste, el de la Alameda Norte registró valores más altos de muerte regresiva, por lo que su condición general de salud se consideraría como la más precaria de las tres Alamedas.

Published: May 2018

Se proponen los estimadores muestrales para el análisis del inventario forestal del ejido Noh Bec y su remedición. Se analizó la información proveniente de 302 conglomerados distribuidos en cuatro estratos de selva mediana subperennifolia establecidos en el 2009. Se probaron los estimadores de razón de medias estratificado (RME), la media de razón estratificado (MRE) y el muestreo aleatorio estratificado (MAE). El estimador de razón se usó para actualizar el inventario mediante la remedición de 22 conglomerados en el año 2012 y así estimar el incremento periódico anual (IPA) y el incremento porcentual anual (IPA %). El IPA y el IPA % en volumen fueron de 3.721 m3 ha-1año-1 y de 3.2 %, respectivamente. Cuando las unidades de muestreo primarias (UMP) son de tamaños iguales se sugiere utilizar RME o MRE, ya que los valores de la media, error estándar y precisión también lo son. Cuando las UMPs son de tamaños desiguales, se alcanza mayor precisión mediante RME. El MAE resultó ser más preciso que el muestreo por conglomerados con RME y MRE. En los inventarios para manejo forestal no es recomendable trabajar con conglomerados como diseño de muestreo para el cálculo de la posibilidad anual o corta anual permisible ya que en áreas pequeñas se obtendrá baja precisión y alto costo comparado con un muestreo tradicional con UMP independientes de conglomerados.

Home, refuse, and reuse during the Early Helladic III to the Middle Helladic I transitional period. A social zooarchaeological study of the Asine bothroi
Authors: Macheridis Stella
Published: May 2018

The practice of digging, using, and filling large pits, cut into the ground and sometimes lined with clay, was extensive from the Early Helladic III to the Middle Helladic Period I (c. 2,200–1,900 BC) in large parts of the Aegean area. This particular type of feature is called bothros and has been reported since the early 20th century from many settlements, mainly from the Greek mainland. Although the bothroi are numerous in the archaeological record, few studies of them have been made. During the excavations at Asine, a prehistoric coastal settlement in the Argolid, a number of bothroi were identified. This paper is a contribution to the study of bothroi, and in particular of the faunal remains found within these features. I propose that the bothros was an important part of the domestic organization at Asine. Not only did it reflect spatial boundaries but it was also vital in the construction of “home”. This is based on the zooarchaeological analysis and subsequent statistical processing of the faunal remains recovered from the features. New radiocarbon dates are presented which are used in establishing a chronology of the bothroi at Asine.
People and plants. Piecing together archaeological and archaeobotanical data to reconstruct plant use and craft activities in Mycenaean Tiryns
Authors: Vetters Melissa , Brysbaert Ann , Ntinou Maria , Tsartsidou Georgia , Margaritis Evi
Published: May 2018

Archaeobotanical data are often employed to reconstruct a site’s or a region’s palaeoecology, human use of plants such as agricultural regimes, and the interplay between vegetation and anthropogenic factors in the palaeoenvironment. This paper aims to show that a context-specific integration of such data helps to guide the focus beyond the macroscale and may thus add significantly to the reconstruction of microscale activity areas. New archaeobotanical data from four different find spots in the Lower Citadel of Tiryns, Greece, dating to the Mycenaean Palatial and Post-Palatial periods highlight the importance of combining the analysis of the fruit/seed macroremains with anthracological and phytolith studies and integrating these results in their archaeological contextual study. Based on the data from botanical non-wood macroremains, wood charcoal, and phytoliths, the paper discusses methodological issues such as differential preservation of archaeobotanical remains that only becomes evident if more than one analytical method is employed. The paper additionally presents a contextual interpretation of archaeological finds and archaeobotanical remains that adds to a holistic picture of specific activity areas, production sequences, and the multifunctional use of installations.
Estudando Língua Portuguesa, História e Geografia por meio da toponímia: uma proposta
Authors: Tavares Marilze , Velasco Denise De Oliveira Barbosa
Published: May 2018

A Toponímia – uma das subdivisões da Onomástica – é a ciência que se ocupa da investigação dos nomes próprios de lugares. No Brasil, muitos estudos já foram e estão sendo desenvolvido nessa área, no entanto, uma perspectiva pouco desenvolvida é a que correlaciona os estudos toponímicos com o ensino. Por isso, neste trabalho pretendemos apresentar um esboço de uma sequência de atividades didáticas que poderia ser aplicada no Ensino Fundamental (EF), tendo o nome próprio de lugar como tema central. Considerando o caráter essencialmente interdisciplinar da Toponímia, as atividades planejadas englobam três disciplinas do currículo escolar: Língua Portuguesa, História e Geografia.

Authors: Klintsova Mariya Nikolaevna
Published: May 2018

The article reveals social and philosophical aspects of the social orphanhood problem in the modern Russian society. Special attention is paid to studying the social orphanhood phenomenon in the context of cultural trauma and anomie of the Russian society. The social orphanhood phenomenon is considered as a result of disunity of the modern Russian society, prevalence of individualistic values over collectivistic ones in individual and social consciousness. The author justifies the necessity to develop efficient family policy aimed at preventing social orphanhood and strengthening the institutions of family, fatherhood and motherhood.
PECULIARITIES OF BUILDING FORTIFIED CHURCHES IN THE NORTH OF FRANCE IN THE XVI-XVII CENTURIES
Authors: Orlov Igor' Ivanovich
Published: May 2018

The article is devoted to the problem of building fortified churches of the XVI-XVII centuries located within the territory of two modern departments of northern France - Aisne and Ardennes. Over the XVI century by improving fortification the fortified churches of this region acquire universal fortification and compositional features, which allows historians without any doubt to refer them to the typology “eglises fortifiees”. Due to their historical necessity regional “eglises fortifiees” up to the XVII century preserved the tendency for improving architectural and compositional schemes both in the aspect of fortification and in the aspect of iconography.
IRKUTSK MUNICIPAL SELF-GOVERNMENT IN THE STRUGGLE AGAINST THE FOOD CRISIS (1914 - FEBRUARY, 1917)
Authors: Dolidovich Olesya Mikhailovna
Published: May 2018

The article analyzes the efforts of Irkutsk municipal self-government to struggle against the food crisis in the years of the First World War. The author shows that at the first stage (July, 1914 - August, 1915) there was established food commission, which consisted of town councilors. It was not efficient due to its consultative and advisory status, lack of permanent staff, censored membership, deficiency of financing. At the second stage (September, 1915 - February, 1917) the commission was reorganized into the Food Committee, the membership of which was extended cardinally at the expense of the representatives of local public bodies. However they had no full voting status and the Committee was still deprived of organizational and financial autonomy. Under the war conditions there appeared urgent necessity to review the Municipal Regulations of 1892.

Telecommunication technologies have been used to bring healthcare expertise to the point of care since the 19th century. In 1878, The Lancet reported the use of the telephone to reduce unnecessary physician visits and, in 1910, a tele-stethoscope had already been described.1 During the mid-20th century, NASA (National Aeronautics and Space Administration) used remote monitoring systems to measure astronauts’ physiological functions. The Space Technology Applied to Rural Papago Advanced Health Care project further developed this field with the Papago Indians in the southwestern U.S.2 However, the greatest strides in remote monitoring technologies for telehealth have occurred over the last 10 years, with a growing evidence base showing their effectiveness in the management of chronic disease.
Touch—High or Low—Is Sometimes More Important Than High Tech
Authors: Shinsato Douglas
Published: May 2018

“Touch,” the ability to connect at a level relevant to those we try to serve, is as important (arguably more important) than deploying the high-level technology our best minds develop. I was treated to an example of this during my visit to Sony Labs several weeks ago to discuss how we might collaborate to accelerate implementation of telehealth technologies. We agreed that bringing the developed world’s healthcare systems into the 21st Century is not an easy task. There are thousands of regulations, millions of healthcare workers whose jobs are at stake, and too many politicians unwilling to tell their voters that their healthcare systems are broken and financially broke.

Telehealth Practically Speaking: Is New York at a Tipping Point?
Authors: Horowitz Ester
Published: May 2018

Medical care is becoming cost prohibitive. Responsiveness and access to care are more difficult. There are reasons and perspectives as to why and how to solve this issue. Yet, despite advances in medicine and technology, delivery of care is more complicated for the average consumer and less rewarding for doctors..

We yearn for the “Norman Rockwell” and “Marcus Welby, MD” experience of the mid-20th century that made society feel they were in good hands and made doctors feel valued in their chosen profession. Enter telehealth and telemedicine. The second fastest growing industry, giving consumers and practitioners more of what they desire: a better experience.

Author’s note: In our 25+ years in the post-acute care provider industry, we have experienced the value of integrating telehealth and remote patient monitoring into our care delivery model, which has improved our ability to care for patients at a substantially reduced cost of care. We knew that there had to be a way to apply these learnings and telemedicine technologies to assist healthcare providers—long-term acute care hospitals, skilled nursing facilities, home health agencies, hospices, etc.—who often lack access to expert wound care, to deliver evidence-based, efficacious wound care to their patients.

Published: May 2018

La sepsis es un síndrome  siempre grave, producida por anormalidades fisiológicas,  patológicas y bioquímicas asociadas a una infección y es responsable de elevada tasa de mortalidad entre las personas hospitalizadas. Varios factores aumentan la susceptibilidad a desarrollarla  siendo representativas las  edades extremas, la comorbilidad asociada, los estados que debilitan el sistema inmunitario y desde el punto de vista clínico las diferencias obedecen sobre todo a la clasificación del germen causal que desencadena la liberación de mediadores tóxicos, siendo muy temidas las causadas por gérmenes gram negativos intraluminales. Presentamos un caso de dolor abdominal de diez días de evolución, tratado empíricamente por métodos caseros en busca de analgesia sin resultados alentadores, el cual acudió al Hospital Provincial General Docente Ambato, Ecuador en el año 2017, donde se decidió operar por Peritonitis Generalizada y Sepsis de posible etiología intraabdominal; evidenciándose al acto operatorio perforación de  Divertículo de Meckel, con sus respectivas complicaciones dado su tórpida evolución que motivó además la realización de procedimientos quirúrgicos derivativos.

La Tuberculosis Genitourinaria  se ha descrito como una de las formas clínicas más  comunes de tuberculosis extrapulmonar, cuyas variaciones están determinadas por diferencias en las situaciones epidémicas. Su diagnóstico ha estado obstaculizado a menudo por la no especificidad de la sintomatología, y la insuficiencia en los sitios asistenciales de los medios de diagnóstico apropiados.  El presente trabajo posibilitó  presentar el caso de un paciente con síntomas de TBGU, diagnosticado en el Hospital General del Instituto Ecuatoriano de Seguridad Social de Ambato, Ecuador en el año 2016, en el que no se pudo identificar estigmas de primoinfección tuberculosa; adicionalmente se constató lo avanzado del proceso, debido a la presencia de una hidronefrosis bilateral por estenosis ureteral distal, que hizo sospechar un estado subyacente de inmunodeficiencia, no confirmado en el estudio clínico del paciente.

Effects of Labour Migration on Poverty and Agricultural Growth in Nepal
Authors: Pant Krishna P
Published: May 2018

Increasing labour shortage in agriculture sector and contribution of remittance on poverty reduction has raised the importance of studies on employment, poverty and agricultural growth nexus. The study explores the effects of foreign employment on poverty and agricultural growth. The study using time series secondary data for 19 years fitted econometric models at sectoral level to establish the effects of migration on poverty and agricultural production. It also compares agricultural output elasticity of foreign employment and assesses the role of foreign employment on the relationships between growth, poverty and agricultural development. The results show that migration decreases poverty and at the same time decreases agriculture production. But, the decrease in agriculture gross domestic product per unit of labour migrated is smaller than the per capita remittance. The study does not dwell on the social and cultural effects of the labour migration. The results will be useful for decision makers to devise sound policies on migration, poverty and agricultural development.
Ricebean in Home Gardens of the Chitwan Valley
Authors: Khadka Kamal , Khanal Aditya R
Published: May 2018

Ricebean is a neglected and underutilized grain legume grown in specific pockets by poor and marginal farmers. Despite being a multipurpose legume, its use in food, fodder and green manure crop were limited to farmers knowledge. Recognizing multiple use of ricebean a reconnaissance survey was conducted in Chitwan valley to assess the potential of ricebean as one of the home garden species in December 2007. Household survey was done to appraise the knowledge on ricebaean and its use. Agro-morphological traits were analysed. The study showed ricebean to be a new crop in the valley. Rice bean is helping the farmers to diversify their diet. Ricebean is also a good source of fodder and farmers believe that ricebean enriches soil fertility in the home gardens. Descriptive analysis of the agro-morphological traits showed diversity in the ricebean accessions grown by the farmers. The study clearly indicated that ricebean can be a potential crop in the home gardens of the Chitwan valley.

Epochality, Global Capitalism and Ecology
Authors: Hope Wayne
Published: May 2018

What type of capitalism do we live in today? My answer to this question draws upon two interrelated lines of argument. Firstly, I will argue that we inhabit an epoch of global capitalism. The precursors of this kind of capitalism originated from the late nineteenth century when the development of telegraph networks, modern transport systems and world time zones provided a global template for industrialisation and Western imperialism. From about 1980 a confluence of global events and processes bought a fully-fledged global capitalism into being. These included the collapse of Fordist Keynesianism, national Keynesianism and Soviet Communism along with First, Second and Third World demarcations; the international proliferation of neo-liberal policy regimes; the growth of transnational corporations in all economic sectors; the predominance of financialisation and the reconstitution of global workforces. Secondly, I will argue that the shift from organic surface energy to underground fossil energy intertwined the time of the earth with the time of human history as nature was being instrumentalised as a resource for humanity. Understanding the capitalist relations of power involved here requires that we rethink the emergence of industrial capitalism in the historical context of a world system built upon unequal socio-ecological exchange between core and periphery. Today, global capitalism has intensified the anthropogenic feedback loops associated with CO2 emissions and climate change and universalised the organisational frameworks of profit extraction and socio-ecological destruction. I refer here to the transnational systems of fossil fuel capitalism along with their interlinkages with financialisation and advertising/commodity fetishism. From the preceding lines of argument I will briefly outline the intra-capitalist and planetary-ecological crises out of which transnational coalitions of opposition might emerge.
Marx and Feminism
Authors: Federici Silvia
Published: May 2018

This contribution focuses on aspects of feminism and gender in Marx’s theory. Marx’s methodology has given us the tools and the categories enabling us to think together gender and class, feminism and anti-capitalism. However, his contribution is an indirect one because Marx never developed a theory of gender. It is important to include the role of reproductive labour, slave labour, migrant labour, labour in the Global South and the unemployed in the critical analysis of capitalism and its division of labour. Reproductive labour is the largest activity on this planet and a major ground of divisions within the working class. A different Marx was discovered in the 1970s by feminists who turned to his work searching for a theory capable of explaining the roots of women’s oppression from a class viewpoint. The result has been a theoretical revolution that has changed both Marxism and Feminism. What was redefined by the realisation of the centrality of women’s unpaid labour in the home to the production of the work-force was not domestic work alone but the nature of capitalism itself and the struggle against it.

Authors: Hardt Michael , Negri Toni
Published: May 2018

This contribution is the first part of a debate between Michael Hardt/Toni Negri and David Harvey on the occasion of Marx’s bicentenary. The discussion focuses on the question of what capitalism looks like today and how it can best be challenged. This contribution asks: In what type of capitalist society are we living today? And what is the Marxian praxis that we need to challenge it? First, this paper analyses capitalism in respect to the extraction of value from the common, immaterial labour, digitisation, automation, and finance capital. The greatest abstraction in the productive process of value, in its implementation of languages, codes, immaterial articulations of being together, cooperation, affective elements, and so forth presents also in the multitude the virtuality of an extraordinary potential of resistance and autonomy from capital. Second, the paper discusses what forms of praxis are needed today. Marxian ontology is constituted and always renewed by class struggle, by the material antagonism that distributes the elements of real being and by the continuous excess of value that living labour expresses. Today, we discuss Marxian praxis in a society where intelligence is put to work at the centre of the productive process. Here emerges with great force the theme of the liberation of humans from work, on the basis of the transformations of work. Marx demonstrates how much cognitive and intellectual activity is central to production, and how much fixed capital is mixed with cognitive labour. In this context, the notion of the appropriation of fixed capital is of key importance for class struggles.

Universal Alienation
Authors: Harvey David
Published: May 2018

This article is part of a debate between David Harvey, Michael Hardt and Toni Negri. It takes Marx’s bicentenary as occasion for an update of his concept of alienation. The paper asks: how are we to interpret universal alienation and from whence does it come? Marx radically reformulated the concept of alienation in the Grundrisse. The humanism of the early Marx can be re-rooted and reconceptualised in the scientific mode proposed in the Grundrisse. In the Grundrisse, the universality of alienation is specific to capitalism’s historical evolution. Today, alienation exists almost everywhere. It exists at work in production, at home in consumption, and it dominates much of politics and daily life. Such trends intensify through the application of information technologies and artificial intelligence. Widespread alienation has resulted in Occupy movements as well as right-wing populism and bigoted nationalist and racist movements. Donald Trump is the President of alienation. The circulation of capital as totality consists of the three key moments of production, circulation and distribution. A lot of contemporary economic struggles are now occurring at the point of realisation rather than at the point of production. Protests are therefore today often expressions of broad-based discontent. Our future is dictated by the need to redeem our debts. Under such conditions democracy becomes a sham. The big question is what forms of social movement can help us get out of the state-finance nexus. The theory of objective alienation along with an understanding of its subjective consequences is one vital key to unlock the door of a progressive politics for the future.
Repeating Marx: Introduction to the Special Issue “Karl Marx @ 200: Debating Capitalism & Perspectives for the Future of Radical Theory”
Authors: Fuchs Christian , Monticelli Lara
Published: May 2018

This introduction sets out the context of the special issue “Karl Marx @ 200: Debating Capitalism & Perspectives for the Future of Radical Theory”, which was published on the occasion of Marx’s bicentenary on 5 May 2018. First, we give a brief overview of contemporary capitalism’s development and its crises. Second, we argue that it is important to repeat Marx today. Third, we reflect on lessons learned from 200 years of struggles for alternatives to capitalism. Fourth, we give an overview of the contributions in this special issue. Taken together, the contributions in this special issue show that Marx’s theory and politics remain key inspirations for understanding exploitation and domination in 21st-century society and for struggles that aim to overcome these phenomena and establishing a just and fair society. We need to repeat Marx today.
Two Questions to Marxist Anthropology
Authors: El Khachab Chihab
Published: May 2018

“Marxist anthropology” is typically understood as a phase within the history of Euro-American anthropology, which is said to have fizzled out in the 1980s. Since some spectres are difficult to chase, however, Marx’s critique of capitalism continues to haunt the discipline’s output, which is not necessarily couched in Marxist language nor inserted in an explicitly Marxist framework. This essay will not diagnose the reasons behind the waning of “Marxist anthropology” according to the discipline’s professional narrative, but it will eschew such boundaries to concentrate on more urgent issues in criticising contemporary capitalism. Two questions are addressed: 1) How can micro- and macro-social scales in social scientific analysis be integrated? and 2) How can we distinguish between conventional ideas and ideologies through which humans guide their lives under capitalism? Anthropology, I argue, can contribute to a strong critique of contemporary capitalism by attending to these questions, which have been integral in Marxist analysis within and beyond the discipline.
Efficacy of posterior decompression and fixation based on ossification-kyphosis angle criteria for multilevel ossification of the posterior longitudinal ligament in the thoracic spine

OBJECTIVE

The range of decompression in posterior decompression and fixation for ossification of the posterior longitudinal ligament in the thoracic spine (T-OPLL) can be established using an index of spinal cord decompression based on the ossification-kyphosis angle (OKA) measured in the sagittal view on MRI. However, an appropriate OKA cannot be achieved in some cases, and posterior fixation is applied in cases with insufficient decompression. Moreover, it is unclear whether spinal cord decompression of the ventral side is essential for the treatment of OPLL. In this retrospective analysis, the efficacy of posterior decompression and fixation performed for T-OPLL was investigated after the range of posterior decompression had been set using the OKA.

METHODS

The MRI-based OKA is the angle from the superior margin at the cranial vertebral body of the decompression site and from the lower posterior margin at the caudal vertebral body of the decompression site to the prominence of the maximum OPLL. Posterior decompression and fixation were performed in 20 patients. The decompression range was set so that the OKA was ≤ 23° or the minimum if this value could not be achieved. Cases in which an OKA ≤ 23° could and could not be achieved were designated as groups U (13 patients) and O (7 patients), respectively. The mean patient ages were 50.5 and 62.1 years (p = 0.03) and the mean preoperative Japanese Orthopaedic Association (JOA) scores were 5.9 and 6.0 (p = 0.9) in groups U and O, respectively. The postoperative JOA score, rate of improvement of the JOA score, number of levels fused, number of decompression levels, presence of an echo-free space during surgery, operative time, intraoperative blood loss, and perioperative complications were examined.

RESULTS

In groups U and O, the mean rates of improvement in the JOA score were 50.0% and 45.6% (p = 0.3), the numbers of levels fused were 6.7 and 6.4 (p = 0.8), the numbers of decompression levels were 5.9 and 7.4 (p = 0.3), an echo-free space was noted during surgery in 92.3% and 42.9% of cases (p = 0.03), the operative times were 292 and 238 minutes (p = 0.3), and the intraoperative blood losses were 422 and 649 ml (p = 0.7), and transient aggravation of paralysis occurred as a perioperative complication in 2 and 1 patient, respectively.

CONCLUSIONS

There was no significant difference with regard to the recovery rate of the JOA score between patients with (group U) and without (group O) sufficient spinal cord decompression. The first-line surgical procedure of posterior decompression and fixation with the range of posterior decompression set as an OKA ≤ 23° before surgery involves less risk of postoperative aggravation of paralysis and may result in a better outcome.
A Novel Approach to Modelling Nanoindentation Instabilities
Authors: Ananthakrishna Garani , Krishnamoorthy Srikanth
Published: May 2018

We review the recently developed models for load fluctuations in the displacement controlled mode and displacement jumps in the load controlled mode of indentation. To do this, we devise a method for calculating plastic contribution to load drops and displacement jumps by setting-up a system of coupled nonlinear time evolution equations for the mobile and forest dislocation densities by including relevant dislocation mechanisms. These equations are then coupled to the equation defining constant displacement rate or load rate. The model for the displacement controlled mode using a spherical indenter predicts all the generic features of nanoindentation such as the elastic branch followed by several force drops of decreasing magnitudes and residual indentation depth after unloading. The stress corresponding to the elastic force maximum is close to the yield stress of an ideal solid. The predicted numbers for all the quantities match experiments on single crystals of Au using a spherical indenter. We extend the approach to model the load controlled nanoindentation experiments that employ a Berkovich indenter. We first identify the dislocation mechanisms contributing to different regions of the F − z curve as a first step for obtaining a good fit to a given experimental F − z curve. This is done by studying the influence of the parameters associated with various dislocation mechanisms on the model F − z curves. The study also demonstrates that the model predicts all the generic features of nanoindentation such as the existence of an initial elastic branch followed by several displacement jumps of decreasing magnitudes and residual plasticity after unloading for a range of model parameter values. Furthermore, an optimized set of parameter values can be easily determined that give a good fit to the experimental load–displacement curves for Al single crystals of ( 110 ) and ( 133 ) orientations. Our model also predicts the indentation size effect in a region where the displacement jumps disappear. The good agreement of the results of the models with experiments supports our view that the present approach can be used as an alternate method to simulations. The approach also provides insights into several open questions.
Pressure-Volume Work for Metastable Liquid and Solid at Zero Pressure

Published: May 2018

Unlike with gases, for liquids and solids the pressure of a system can be not only positive, but also negative, or even zero. Upon isobaric heat exchange (heating or cooling) at p = 0, the volume work (p-V) should be zero, assuming the general validity of traditional δW = dWp = −pdV equality. This means that at zero pressure, a special process can be realized; a macroscopic change of volume achieved by isobaric heating/cooling without any work done by the system on its surroundings or by the surroundings on the system. A neologism is proposed for these dWp = 0 (and in general, also for non-trivial δW = 0 and W = 0) processes: “aergiatic” (from Greek: Ἀεργία, “inactivity”). In this way, two phenomenologically similar processes—adiabatic without any heat exchange, and aergiatic without any work—would have matching, but well-distinguishable terms.

Bagged Decision Trees Based Scheme of Microgrid Protection Using Windowed Fast Fourier and Wavelet Transforms
Authors: Netsanet Solomon , Zhang Jianhua , Zheng Dehua
Published: May 2018

Microgrids of varying size and applications are regarded as a key feature of modernizing the power system. The protection of those systems, however, has become a major challenge and a popular research topic because it involves greater complexity than traditional distribution systems. This paper addresses this issue through a novel approach which utilizes detailed analysis of current and voltage waveforms through windowed fast Fourier and wavelet transforms. The fault detection scheme involves bagged decision trees which use input features extracted from the signal processing stage which are selected by correlation analysis. The technique was tested on a microgrid model developed using PSCAD/EMTDS, which is inspired from an operational microgrid in Goldwind Science Technology Co. Ltd., in Beijing, China. The results showed a great level of effectiveness to accurately identify faults from other non-fault disturbances, precisely locating the fault and trigger opening of the right circuit breaker/s under different operation modes, fault resistances, and other system disturbances.
