Practical Solution for Temperature Control for Inertial Object
Authors: Mężyk Jordan
Published: July 2016

The issue of temperature control in the research devices is well known and well described in the literature. Yet in the practical applications, in every-day engineering practice there are situations where theoretical knowledge is not applicable in a straight forward manner and the proper settings of the controller parameters constitutes a problem to be addressed and solved with and individual approach. This article presents an example of commissioning of a heated test chamber that is a part of a research apparatus for testing the erosive wear of materials, developed and built at the Institute for Sustainable Technologies – National Research Institute in Radom.The test apparatus is used for eroding the surface of the tested sample with a stream of a mixture of air and an abrasive medium. The test can be performed in room temperature and in raised temperature, both for the ambient of the sample as well as for the air used to make a mixture. The maximal temperature allowed in the machine is 600°C, so the test chamber is equipped with a hermetic door and heat insulation. The construction of the chamber makes it very inertial in terms of heating and cooling, which makes the temperature control a bit challenging.The system is controlled with a PLC with software PID controller implemented in Temperature Controller library. The use of standard set-up of PID parameters resulted in heating with significant overshoot and long settling time which was unacceptable. Trials to tune the parameters with use of built-in algorithm resulted in slower heating and still didn’t eliminate the overshoot. The literature research and tests were performed to identify the problem and to implement simple solution.The article presents the selected results of the literature research and details on the performed tests. The algorithm of the final solution is presented and the characteristics of the heating process after the modification of the control algorithm. The final solution of the issue is an algorithm that uses the standard available temperature controller and the temperature monitor to influence the actions of the controller. The difficulties in identification of the control object (the chamber) caused the inability to solve the problem analytically, but the practical and empirical approach and several trials and errors allowed for the almost optimal control characteristics, which allows no overshoot and as fast as possible heating of the object.

The role of Ab and B cells in preventing infection is established. In contrast, the role of B cell responses in containing chronic infections remains poorly understood. IgG2a (IgG1 in humans) can prevent acute infections, and T-bet promotes IgG2a isotype switching. However, whether IgG2a and B cell–expressed T-bet influence the host–pathogen balance during persisting infections is unclear. We demonstrate that B cell–specific loss of T-bet prevents control of persisting viral infection. T-bet in B cells controlled IgG2a production, as well as mucosal localization, proliferation, glycosylation, and a broad transcriptional program. T-bet controlled a broad antiviral program in addition to IgG2a because T-bet in B cells was important, even in the presence of virus-specific IgG2a. Our data support a model in which T-bet is a universal controller of antiviral immunity across multiple immune lineages.

IL-15 has been implicated as a key regulator of T and NK cell homeostasis in multiple systems; however, its specific role in maintaining peripheral T and NK cell populations relative to other γ-chain (γc) cytokines has not been fully defined in primates. In this article, we address this question by determining the effect of IL-15 inhibition with a rhesusized anti–IL-15 mAb on T and NK cell dynamics in rhesus macaques. Strikingly, anti–IL-15 treatment resulted in rapid depletion of NK cells and both CD4+ and CD8+ effector memory T cells (TEM) in blood and tissues, with little to no effect on naive or central memory T cells. Importantly, whereas depletion of NK cells was nearly complete and maintained as long as anti–IL-15 treatment was given, TEM depletion was countered by the onset of massive TEM proliferation, which almost completely restored circulating TEM numbers. Tissue TEM, however, remained significantly reduced, and most TEM maintained very high turnover throughout anti–IL-15 treatment. In the presence of IL-15 inhibition, TEM became increasingly more sensitive to IL-7 stimulation in vivo, and transcriptional analysis of TEM in IL-15–inhibited monkeys revealed engagement of the JAK/STAT signaling pathway, suggesting alternative γc cytokine signaling may support TEM homeostasis in the absence of IL-15. Thus, IL-15 plays a major role in peripheral maintenance of NK cells and TEM. However, whereas most NK cell populations collapse in the absence of IL-15, TEM can be maintained in the face of IL-15 inhibition by the activity of other homeostatic regulators, most likely IL-7.

The lack of balanced use of fertilizers is one of the reasons for the low yield and the low quality of kiwifruits in Gilan Province, Iran. In order to determine a suitable fertilization planning for kiwi orchards ( Actinidia deliciosa L. cv. Hayward) in Astaneh Ashrafieh, an experiment was performed in 10 treatments with 3 replications based on a randomized complete block design with different amounts of fertilizers in different fertilizing methods. Treatments include different amounts of macro- and micronutrient fertilizers with foliar spraying of calcium, zinc, and potassium in different stages. In this study, the yield of each tree, the fruit firmness, sugar, pH, wet weight, percentage of dry matter, and the content of macronutrients (nitrogen, phosphorus, and potassium) and micronutrients (iron, zinc, and manganese) in the fruit were measured. The results showed that the treatment of 350 g urea, 500 g potassium sulfate, 500 g superphosphate, 80 g iron sulfate sprayed foliarly with 5 parts per thousand of zinc chelate and iron chelate, and foliar spraying with 0.5% of calcium during several stages for each tree has the highest effect on the yield of each tree, the fruit firmness, the fruit pH, and the percentage of the fruit dry matter, so such a yield of this treatment showed a difference of 7.9 kg with control.

Schistosomiasis is the second most significant parasitic disease in children in several African countries. For this purpose, the “Programme National de Lutte contre les Bilharzioses” (PNLB) was developed in partnership with the World Health Organization (WHO) to control this disease in Senegal. However, geographic isolation of Bedik ethnic groups challenged implementation of the key elements of the schistosomiasis program in eastern Senegal, and therefore, a hospital was established in Ninefescha to improve access to health care as well as laboratory support for this population. The program we have implemented from 2008 in partnership with the PNLB/WHO involved campaigns to 1) evaluate schistosomiasis prevalence in children of 53 villages around Ninefescha hospital, 2) perform a mass drug administration following the protocol established by the PNLB in school-aged children, 3) monitor annual prevalence, 4) implement health education campaigns, and 5) oversee the building of latrines. This campaign led to a drop in schistosomiasis prevalence but highlighted that sustainable schistosomiasis control by praziquantel treatment, awareness of the use of latrines, and inhabitants' voluntary commitment to the program are crucial to improve Schistosoma elimination. Moreover, this study revealed that preschool-aged children, for whom praziquantel was not recommended until 2014 in Senegal, constituted a significant reservoir for the parasite.

In Senegal, tick-borne relapsing fever (TBRF) is a major cause of morbidity and a neglected public health problem. Borreliosis cases commonly detected in two villages led us to implement a borreliosis preventive control including cementing of floors in bedrooms and outbuildings attended by inhabitants to avoid human contacts with tick vectors. Epidemiological and medical monitoring of the TBRF incidence was carried out at Dielmo and Ndiop by testing the blood of febrile patients since 1990 and 1993, respectively. Intra-domiciliary habitat conditions were improved by cementing, coupled with accompanying measures, from March 2013 to September 2015. Application of this strategy was associated with a significant reduction of borreliosis incidence. This was more evident in Dielmo, dropping from 10.55 to 2.63 cases per 100 person-years (P < 0.001), than in Ndiop where it changed from 3.79 to 1.39 cases per 100 person-years (P < 0.001). Thirty-six cases of TBRF were estimated to be prevented at a cost of €526 per infection. The preventive control strategy was successful in Dielmo and Ndiop, being associated with decreased incidence by 89.8% and 81.5%, respectively, suggesting that TBRF may be widely decreased when the population is involved. Public health authorities or any development stakeholders should adopt this effective tool for promoting rural health through national prevention programs.
Decline in Child Hospitalization and Mortality After the Introduction of the 7-Valent Pneumococcal Conjugative Vaccine in Rwanda
Authors: Rurangwa Janvier , Rujeni Nadine
Published: July 2016

Pneumonia is a public health problem in the tropics, and the 7-valent pneumococcal conjugative vaccine (PCV-7) has been introduced in an effort to prevent the disease and therefore reduce childhood mortality. In Rwanda, PCV-7 was introduced in 2009, and we aimed to determine its impact on the rate of child hospitalization/mortality due to pneumonia. A retrospective survey was conducted on hospitalization rates and pediatric deaths between two periods, that is, before the introduction of PCV-7 (2007–2009) and after the introduction of PCV-7 (2010–2013) in Kabutare District Hospital. There was a 53% reduction in hospitalization, with a significant decline in in-hospital deaths between the two periods. There was also a significant correlation between vaccination coverage and decline in hospitalization rates between 2009 and 2013. We conclude that PCV-7 vaccine is associated with significant reduction in the rate of child hospitalization and mortality but more mechanistic studies are warranted to determine the immunological impact, especially in the context of coinfections and malnutrition.
Augusto Graziani's Equilibrio generale ed equilibrio macroeconomico: a key milestone in a long journey out of the neoclassical mainstream
Authors: Cingolani Massimo
Published: July 2016

Educated in the best Italian cultural and economic tradition, Augusto Graziani was a scholar of great finesse and erudition. These qualities come out clearly in Equilibrio generale ed equilibrio macroeconomico (1965a), interpreted here as the initial step in a process that eventually brought Graziani to the final rejection of methodological individualism and the reconstruction of microeconomics on macroeconomic bases achieved with The Monetary Theory of Production (2003). In his 1965 book, Graziani shows that, save for the Sraffian–Kaldorian heterodox alternative, extending Walras to dynamics in a multisectoral framework requires assumptions logically equivalent to those of single good models. This also points implicitly towards the need of interpreting the mainstream temporary equilibrium method in terms of path dependency when it refers to multiple sectors, and thus precludes that it converges towards a ‘plain’, long-term intertemporal general equilibrium. The latter is a notion generally associated with the name of Walras and early marginalists, but which owes much to later developments by Hayek, Lindahl and Hicks.

For the single period, Graziani's work on the monetary circuit can be read as an original variant of the monetary temporary equilibrium of Myrdal, where money and debt, combined with errors in exogenous expectations, explain the path-dependency of short-term equilibria. For continuation analysis, this is completed with insights from Wicksell, Schumpeter, Marx and Kalecki, whereby the circuit provides a simple explanation of the Keynesian fallacy of composition critique of microeconomics.

But the book is also an important contribution to an Italian debate on capital theory, which emerged mainly in Il Giornale degli Economisti in the 1960s, in parallel with the more cosmopolitan ‘two Cambridge capital controversies’ that developed at the same time in the top American and British journals. Both originated in Sraffa's famous 1960 contribution and should thus be examined together.
Graziani's analysis of the circuit: does it extend to the era of financialisation?
Authors: Sawyer Malcolm
Published: July 2016

This paper outlines some key features of the circuitist analysis provided by Augusto Graziani, and some key features of the processes of financialisation. It argues that the key features of the monetary circuit analysis remain relevant and indeed central to a monetary analysis. It presents a development of a circuit analysis in which some features of financialisation are incorporated. It argues that the circuitist approach provides a framework within which the detailed analysis of a specific monetary economy can be located.

Abstract. A large-scale comparison of water-vapour vertical-sounding instruments took place over central Europe on 17 October 2008, during a rather homogeneous deep stratospheric intrusion event (LUAMI, Lindenberg Upper-Air Methods Intercomparison). The measurements were carried out at four observational sites: Payerne (Switzerland), Bilthoven (the Netherlands), Lindenberg (north-eastern Germany), and the Zugspitze mountain (Garmisch-Partenkichen, German Alps), and by an airborne water-vapour lidar system creating a transect of humidity profiles between all four stations. A high data quality was verified that strongly underlines the scientific findings. The intrusion layer was very dry with a minimum mixing ratios of 0 to 35 ppm on its lower west side, but did not drop below 120 ppm on the higher-lying east side (Lindenberg). The dryness hardens the findings of a preceding study (“Part 1”, Trickl et al., 2014) that, e.g., 73 % of deep intrusions reaching the German Alps and travelling 6 days or less exhibit minimum mixing ratios of 50 ppm and less. These low values reflect values found in the lowermost stratosphere and indicate very slow mixing with tropospheric air during the downward transport to the lower troposphere. The peak ozone values were around 70 ppb, confirming the idea that intrusion layers depart from the lowermost edge of the stratosphere. The data suggest an increase of ozone from the lower to the higher edge of the intrusion layer. This behaviour is also confirmed by stratospheric aerosol caught in the layer. Both observations are in agreement with the idea that sections of the vertical distributions of these constituents in the source region were transferred to central Europe without major change. LAGRANTO trajectory calculations demonstrated a rather shallow outflow from the stratosphere just above the dynamical tropopause, for the first time confirming the conclusions in “Part 1” from the Zugspitze CO observations. The trajectories qualitatively explain the temporal evolution of the intrusion layers above the four stations participating in the campaign.
Turbulence kinetic energy budget during the afternoon
transition – Part 1: Observed surface TKE budget and boundary layer
description for 10 intensive observation period days

Published: July 2016

Abstract. The decay of turbulence kinetic energy (TKE) and its budget in the afternoon period from midday until zero-buoyancy flux at the surface is studied in a two-part paper by means of measurements from the Boundary Layer Late Afternoon and Sunset Turbulence (BLLAST) field campaign for 10 intensive observation period days. Here, in Part 1, near-surface measurements from a small tower are used to estimate a TKE budget. The overall boundary layer characteristics and mesoscale situation at the site are also described based upon taller tower measurements, radiosoundings and remote sensing instrumentation. Analysis of the TKE budget during the afternoon transition reveals a variety of different surface layer dynamics in terms of TKE and TKE decay. This is largely attributed to variations in the 8 m wind speed, which is responsible for different amounts of near-surface shear production on different afternoons and variations within some of the afternoon periods. The partitioning of near-surface production into local dissipation and transport in neutral and unstably stratified conditions was investigated. Although variations exist both between and within afternoons, as a rule of thumb, our results suggest that about 50 % of the near-surface production of TKE is compensated for by local dissipation near the surface, leaving about 50 % available for transport. This result indicates that it is important to also consider TKE transport as a factor influencing the near-surface TKE decay rate, which in many earlier studies has mainly been linked with the production terms of TKE by buoyancy and wind shear. We also conclude that the TKE tendency is smaller than the other budget terms, indicating a quasi-stationary evolution of TKE in the afternoon transition. Even though the TKE tendency was observed to be small, a strong correlation to mean buoyancy production of −0.69 was found for the afternoon period. For comparison with previous results, the TKE budget terms are normalized with friction velocity and measurement height and discussed in the framework of Monin–Obukhov similarity theory. Empirically fitted expressions are presented. Alternatively, we also suggest a non-local parametrization of dissipation using a TKE–length scale model which takes into account the boundary layer depth in addition to distance above the ground. The non-local formulation is shown to give a better description of dissipation compared to a local parametrization.
Air–surface exchange of gaseous mercury over permafrost soil: an
investigation at a high-altitude (4700 m a.s.l.) and remote site in the central
Qinghai-Tibet Plateau
Authors: Ci Zhijia , Peng Fei , Xue Xian , Zhang Xiaoshan
Published: July 2016

Abstract. The pattern of air–surface gaseous mercury (mainly Hg(0)) exchange in the Qinghai-Tibet Plateau (QTP) may be unique because this region is characterized by low temperature, great temperature variation, intensive solar radiation, and pronounced freeze-thaw process of permafrost soils. However, air–surface Hg(0) flux in the QTP is poorly investigated. In this study, we performed filed measurements and controlled field experiments with dynamic flux chambers technique to examine the flux, temporal variation and influencing factors of air–surface Hg(0) exchange at a high-altitude (4700 m a.s.l.) and remote site in the central QTP. The results of field measurements showed that surface soils were net emission source of Hg(0) in the entire study. Hg(0) flux showed remarkable seasonality with net high emission in the warm campaigns and net low deposition in winter campaign, and also showed the diurnal pattern with emission in daytime and deposition in nighttime, especially on days without precipitation. Rainfall events on the dry soils induced large and immediate increase in Hg(0) emission. Snowfall events did not induce the pulse of Hg(0) emission, but snow melt resulted in the immediate increase in Hg(0) emission. Daily Hg(0) fluxes on rainy or snowy days were higher than those of days without precipitation. Controlled field experiments suggested that water addition to dry soils significantly increased Hg(0) emission both in short and relatively long timescales, and also showed that UV radiation was primarily attributed to Hg(0) emission in the daytime. Our findings imply that a warm climate and environmental change could facilitate Hg release from the permafrost terrestrial ecosystem in the QTP.

Published: July 2016

Abstract. Astronauts on board the International Space Station (ISS) have taken thousands of high-resolution colour photographs of the aurora, which could be made useful for research if their pointing information could be reconstructed. We describe a method to do this using the star field in the images, and how the reconstructed pointing can then be used to georeference the images to a similar level of accuracy in existing all-sky camera images. We have used this method to make georeferenced auroral images taken from the ISS available and here describe the resulting data set, processing software, and how to access them.

Interfaces como metacomunicação: contribuição da engenharia semiótica na representação no ciberespaço
Authors: Santos Miriam Cristina Fava , Monteiro Silvana Drumond
Published: July 2016

Introdução: O ciberespaço com suas características interativas trouxe novos desafios para a representação do conhecimento, devido as mudanças tecnológicas, o protagonismo dos sujeitos em ambientes de informação digital e a experiência que esses ambientes podem fornecer. A interação no ciberespaço pode ser vista como um processo de indicações recíprocas, em que o designer deve indicar como outra pessoa pode agir. Nesse processo, o sujeito informacional não é um agente passivo, ele é chamado à interpretação. A metacomunicação leva o designer a se preocupar em prever as necessidades levando em conta a visão de quem esse sujeito é, o que ele busca na Interface e por meio dela. 

Objetivo: 1) Analisar as Interfaces como Metacomunicação do designer no ciberespaço.  2) Identificar a contribuição da Engenharia Semiótica para o designer no processo de significação e representação nas interfaces.

Metodologia: Para efetuar a Análise Documental, utilizou-se a técnica de análise categorial, ou seja, um desmembramento dos signos estáticos, dinâmicos e metalinguísticos da Teoria da Engenharia Semiótica, comparando-os com a divisão triádica dos signos de Peirce (ícone, índice e símbolo) no corpus selecionado: sites da Biblioteca Nacional da Austrália e da Biblioteca do Congresso dos Estados Unidos.

Resultados: Percebeu-se uma maior preocupação do designer da Biblioteca do Congresso dos Estados Unidos para a metacomunicação, pois o designer criou mais rotas e indicações para caminhos que antecipavam as possíveis intenções dos sujeitos informacionais na busca pelo conhecimento. Conclusões: A Teoria da Engenharia Semiótica contribui com a Ciência da Informação na busca por representar melhor o conteúdo ao trazer o conceito da Interface como Metacomunicação do designer para o sujeito informacional que navega no ciberespaço, ambos mentes interpretadoras e produtoras de conhecimento.

BACKGROUND: The effect of controlling blood sugar on decreasing diabetes complications and their fatality has been investigated in many cross-sectional studies, but instability of blood sugar and some of the potential effective factors on it during the time render these studies imprecise and unreliable. Exploring among a big number of possible covariates is another challenging issue which renders the traditional methods inefficient. Therefore, we aimed to determine factors which are mostly associated with HbA1c level, among a large number of potential covariates using penalized linear mixed model in a longitudinal study

METHOD: The participants consisted of diabetic patients referred to Endocrine and Metabolism Research Center of Isfahan from 2000 to 2012 who were measured 4-12 times. Linear mixed model with LASSO penalty was used to investigate the relationship between HbA1c and the factors which potentially affect HbA1c. SPSS version 18 and glmmLassopackage in R. 3.1.3 software were used for statistical analysis.

RESULTS: Most of the 360 patients, (62.5%) were female. Their mean age was 52.2 years (SD=9.24) and median number of their visit was 5 with inter-quartile range of 4 to 6. The simple mixed model revealed that all of the covariates had significant effects on HbA1c, but using LMMLASSO led to elimination of 8 redundant covariates from the final model.

CONCLUSION: By Appling linear mixed model with LASSO penalty retinopathy, hypertension, cholesterol, HDL and TG had the most significant association with HbA1c level.

Authors: Leite Maria Jorge Dos Santos
Published: July 2016

O objetivo desse trabalho é analisar o processo de construção identitária da comunidade quilombola de Conceição das Crioulas, observando o entrelaçamento étnico-cultural entre seus habitantes e os da aldeia indígena Atikum. Ambas são comunidades tradicionais localizadas no sertão de Pernambuco.  Devido à proximidade geográfica entre as duas comunidades e as múltiplas relações historicamente estabelecidas entre elas, há evidências de que há certa assimilação da cultura indígena pela população quilombola, o mesmo acontecendo com os índios Atikum.

Etnicidade de hutus e tutsis no Manifesto Hutu de 1957 (Ethnicity of Tutsis and Hutus in the 1957 Hutu Manifest)
Authors: Fonseca Danilo Ferreira da
Published: July 2016

O presente artigo visa refletir acerca do modo com que a etnicidade de hutus e tutsi é vivenciada e problematizada na turbulenta década de 1950 de Ruanda, principalmente devido ao processo de independência frente a Bélgica, que foi concretizado em 1962. O foco principal está na maneira que o chamado “Manifesto hutu”, de 1957, compreende e divulga múltiplas faces acerca da etnicidade de hutus e tutsis, envolvendo a relação construída entre os dois grupos e o seu sentimento de pertencimento. O movimento emancipatório de Ruanda possibilita novas reflexões acerca da unidade nacional ruandesa e do pertencimento étnico que os hutus constroem acerca de si mesmos e acerca dos tutsis, em um movimento que funde elementos tradicionais e modernos a partir dos costumes locais e da inserção de instituições ocidentais no país. Tais elementos são centrais para a construção da Revolução hutu de 1959, que rompe com a dominação aristocrática dos tutsis e traz cicatrizes históricas profundas que são reabertas em diferentes momentos da história ruandesa, inclusive no próprio genocídio ocorrido em 1994.

The main focus is on so that the called "Hutu Manifest" of 1957 comprises and discloses multiple faces on the ethnicity of Hutus and Tutsis, involving the relationship built between the two groups and their sense of belonging. The emancipatory movement of Rwanda provides new insights about the Rwandan national unity and ethnic belonging that Hutus build about themselves and about the Tutsis, in a move that merge traditional and modern elements from the local customs and the inclusion of estern institutions in the country. These elements are central to Hutu revolution of 1959 building that breaks with the aristocratic domination of Tutsis and back deep historical scars that are reopened at different times of Rwandan history, including genocide occurred in 1994.

Diásporas africanas e contatos afroindígenas na Amazônia Marajoara (African diasporas and afroindígenas contacts in Marajoara Amazon)
Authors: Pacheco Agenor Sarraf
Published: July 2016

Este artigo percorre evidências históricas das diásporas africanas na Amazônia Marajoara e das intersecções tecidas por índios e negros desde o período colonial. Focaliza descobertas e sentidos na escrita do saber acerca da temática e questiona o lugar da região na compreensão mais ampla e inclusiva da história da Amazônia. Em seguida, procura mapear e discutir o processo de colonização do grande arquipélago, formação dos latifúndios, introdução da mão de obra africana, bem como fugas e práticas de solidariedade entre nativos e diaspóricos na constituição de mocambos e quilombos entre campos e florestas marajoaras. Fundamentado nos Estudos Culturais e no Pensamento Pós-Colonial e Decolonial, analisa experiências dos variados sujeitos históricos na compreensão das zonas de contato e mediações interculturais, deixando ver que entre idas e vindas, índios e negros recriaram costumes, renovaram e readaptaram rituais, festas e tradições na ambiguidade de viveres sempre domados e regidos pelo invencível regime das águas marajoara. Nessas simbioses, as Áfricas foram recriadas na Amazônia Marajoara, assim como as identidades de homens e mulheres marajoaras de matrizes afroindígenas vêm sendo reinventadas ao longo da história regional.
