Authors: Liu Bin , Zhu Shun Ying , Wang Hong
Published: January 2015

135 Subjectively Equal Speed experiments were designed by using the Forced-Choice Method, 6 males and 2 females’ experiment results indicated that fog exerts a two-way influence to the driver's speed perception. When visibility was low (e.g:39m), fog resulted in overestimation of the speed, When visibility was higher, fog resulted in underestimation of the speed, it is not in accordance with one-way influence of Anstis and Snowden. Have analyzed the reason why the experimental result is inconsistent and emerge in terms of light stream rate and contrast ratio in thesis. When visibility is low, the nearby optical flow rate is great which cause the driver overestimate the speed; When visibility is higher, the decline of contrast cause the driver underestimate the speed.

Vehicle Height Control of Automotive Air Suspension System Using Fuzzy Neural Network Approach
Authors: Shan Hong Yan
Published: January 2015

Vehicle height adjustment is one of the main features of automotive air suspension system, which plays a significant role to improve driving stability and fuel economy of the vehicle. However, direct open-loop control can’t achieve the vehicle height control with high precision for undesirable phenomenon of over-charge and over-discharge of the air spring. Therefore, a fuzzy neural network approach was proposed in this paper for designing the vehicle height controller. According to the operational principle of the vehicle height adjustment process, the system mathematical model was established based on vehicle system dynamics and variable mass charge/discharge gas system thermodynamic theory. Then, the fuzzy neural network control laws were designed based on the nonlinear model to maximize the control accuracy. Finally, the effectiveness and applicability of the proposed control algorithm are verified by simulation results.

Fault Diagnosis Simulation of a Space Propulsion System Based on Fuzzy Rule Set Neural Network Method
Authors: Huang Min Chao , Xing Bao Yu
Published: January 2015

Based on fuzzy rule sets match method which is a series of fuzzy neural networks, a system framework used for the fault diagnosis is proposed. This fault diagnosis system consists of five parts, including the extraction of fuzzy rules, fuzzy reference rule sets, the fuzzy rule scheduled to detect, the fuzzy match module and the diagnosis logic module. The extraction of fuzzy rules involves two steps: step one adaptively divides the whole space of the trained data into the subspaces in the form of hypersphere, which is expected efficiently to work out the recognition questions in the high dimension space; step two generates a fuzzy rule in each sample subspace and calculates the membership degree of each fuzzy rule. Many fuzzy reference rule sets are produced by the extraction module of fuzzy rules for the offline learning, and a fuzzy rule set to be detected is online formed while the monitoring process is happening. Beliefs estimated from the fuzzy match process of fuzzy rule sets, which indicate the existence of the working classes in the plant, the diagnosis logic module can export fault detection time, fault isolation time, fault type and fault degree. The simulation researches of the fault diagnosis in space propulsion system demonstrate the superior qualities of the fault diagnosis method on the basis of the fuzzy match of the fuzzy rule sets.

Authors: Feng Shuo , Wang Zhong Qi , Xue Hong Qian
Published: January 2015

Tool wear can affect surface quality of the work-piece and frequent tool changing leads to low machining efficiency. Tool life of milling ultrahigh strength steel is thus an important indicator in manufacturing. In this study, we compare Diffuse Approximation (DA) and Kriging method for predicting tool life of milling ultrahigh strength steel. Latin hypercube method is employed as design of experiments after comparing three different designs of experiments (full factorial design, Latin Hypercube Sampling (LHS) and random design). An example with LHS is taken to investigate accuracy of approximation of DA and Kriging method. The results show that the DA provides significant improvement in accuracy of prediction compared with Kriging method. Tool life of milling ultrahigh strength steel predicted by DA is almost close to ‘exact’ values, especial for big mutation of adjacent measured values. The most errors with DA are less than ones with Kriging method.

Authors: Sandulyak Alexander , Sandulyak Anna , Shkatov Petr
Published: January 2015

We note that for a wide range of porous, especially granular, ferromagnetics used as matrices of magnetic filter-separators, there is still an issue of defining their demagnetizing factor N which has a dramatic effect on the values of average magnetic permeability of these operating units of filter-separators. The work aims at filling the existent gaps in the issue, we supply N values depending on the relative size of such magnets as well as a respective generalizing phenomenological dependence which is characterized by an exponential realtion between the demagnetizing factor and relative size radical. The established relation allows obtaining real values of magnetic permeability of a short filter matrix thus providing an unbiased comparative estimate of its technological workability.

Published: January 2015

I present the systematics and distribution of a new species of oribatid mite in the genus Metrioppia Grandjean, 1931 (Oribatida: Peloppiidae) from western North America. Metrioppia walbranensisnew species is diagnosed on the basis of adult morphology using the following character states: shape and dentition of the rostrum, length of lamellae, shape of lamellar cusps, length of the interlamellar setae, and number of posterior notogastral setae. The known distribution of M. walbranensis is provided based on sampling and museum collections. Metrioppia walbranensis has been collected only from a small number of locations on south-west Vancouver Island, British Columbia, Canada, while its congener M. oregonensis Woolley and Higgins, 1969 has been collected widely within the Pacific Northwest, including sites on Vancouver Island. However, the two species do not appear to co-occur. Nucleotide sequence of the COI gene firmly places Metrioppia within the family Peloppiidae.
Tim-1 Is Essential for Induction and Maintenance of IL-10 in Regulatory B Cells and Their Regulation of Tissue Inflammation
Authors: Xiao Sheng , Brooks Craig R. , Sobel Raymond A. , Kuchroo Vijay K.
Published: January 2015

T cell Ig and mucin domain (Tim)-1 identifies IL-10–producing regulatory B cells (Bregs). Mice on the C57BL/6 background harboring a loss-of-function Tim-1 mutant showed progressive loss of IL-10 production in B cells and with age developed severe multiorgan tissue inflammation. We demonstrate that Tim-1 expression and signaling in Bregs are required for optimal production of IL-10. B cells with Tim-1 defects have impaired IL-10 production but increased proinflammatory cytokine production, including IL-1 and IL-6. Tim-1–deficient B cells promote Th1 and Th17 responses but inhibit the generation of regulatory T cells (Foxp3+ and IL-10–producing type 1 regulatory T cells) and enhance the severity of experimental autoimmune encephalomyelitis. Mechanistically, Tim-1 on Bregs is required for apoptotic cell (AC) binding to Bregs and for AC-induced IL-10 production in Bregs. Treatment with ACs reduces the severity of experimental autoimmune encephalomyelitis in hosts with wild-type but not Tim-1–deficient Bregs. Collectively, these findings suggest that in addition to serving as a marker for identifying IL-10–producing Bregs, Tim-1 is also critical for maintaining self-tolerance by regulating IL-10 production in Bregs.

Clinical Management of Familial Hypercholesterolemia: New Insights from International Guidelines and Recent Studies
Authors: Wierzbicki Anthony
Published: January 2015

This review article assesses the clinical features, diagnosis and management of familial hypercholesterolemia (FH). FH is mostly an autosomally dominantly inherited with an incidence of 1 in 250. Tendon xanthomata are pathognomonic. Untreated FH is associated with 100-200 fold increase in risk of cardiovascular disease (CVD). FH is diagnosed by screening for elevated low density lipoprotein cholesterol (LDL-C) and confirmed by DNA techniques. Once index cases have been identified cascade family screening should occur. FH is primarily treated with high dose statin therapy. This reduces progression of surrogate markers of coronary arterial disease and registry studies show a 70% long-term decrease in CVD mortality. The justification for other lipidlowering therapies e.g., ezetimibe relies on the high population attributable risk of LDL-C in FH. Novel therapies with greater LDL-C reducing actions such as proprotein convertase subtilisin kexin-9 inhibitors show promise in FH Children with FH should be identified through cascade screening but drug treatment is dependent on LDL-C and family history. They should be managed in specialist paediatric units or in family clinics. Cases of homozygous FH are rare. This orphan condition should be managed in specialist centers with a combination of drug therapy, apheresis and liver transplantation. Novel therapies for the treatment of homozygous FH such as mipomersen and lomitapide are gradually coming into use FH is a common underdiagnosed condition. Current, let alone future, therapies are extremely effective in reducing both LDL-C and CVD events in patients with FH. Identification and treatment of FH should be a feature of preventative CVD medicine programmes.
How older persons structure information in the decision to seek medical care
Authors: Veazie Peter J.
Published: January 2015

Typical models of the decision to seek care consider information as a single conceptual object. This paper presents an alternative that allows multiple objects. For older persons seeking care, results support this alternative. Older decision-makers that segregate information into multiple conceptual objects assessed separately are characterized by socio-demographic (younger age, racial category, non-Hispanic, higher education, higher income, and not married), health status (better general health for men and worse general health for women, fewer known illnesses), and neuropsychological (less memory loss for men, trouble concentrating and trouble making decisions for men) factors. Results of this study support the conclusion that older persons are more likely to integrate information, and individuals with identifiable characteristics are more likely to do so than others. The theory tested in this study implies a potential explanation for misutilization of care (either over or under-utilization).
Factors influencing the predation rates of Anisops breddini (Hemiptera: Notonectidae) feeding on mosquito larvae
Authors: Weterings R. , Vetter K.C. , Umponstira C.
Published: January 2015

Notonectidae are a family of water bugs that are known to be important predators of mosquito larvae and have great potential in the biological control of vector mosquitoes. An experiment was conducted to assess mosquito larvae predation by Anisops breddini, a species common to Southeast Asia. The predation rates were recorded in context of prey density, predator density, predator size and prey type. Predation rates were strongly affected by prey type and less by prey density and predator density. They ranged between 1.2 prey items per day for pupae of Aedes aegeypti and Armigeres moultoni to 5.9 for Ae. aegypti larvae. Compared with studies on other Notonectidae species, the predation rates appear low, which is probably caused by the relative small size of the specimens used in this study. An. breddini is very common in the region and often found in urban areas; therefore, the species has potential as a biological control agent.

Published: January 2015

A colony of the encyrtid wasp Psyllaephagus euphyllurae (Masi) (Hymenoptera, Encyrtidae) has been established in the quarantine laboratory at the University of California, Riverside, California, USA as part of a classical biological control program against its invasive host, the olive psylla, Euphyllura olivina (Costa) (Hemiptera, Psylloidea, Liviidae), an important pest of olives in some parts of the world. The colony originators were reared from the same host found on abandoned, commercial olives in Catalonia, Spain; additional collections were made in Murcia. The parasitoid reproduces primarily by thelytoky; however, a few occasional males have been found in the field in Spain, but not in colonies reared under quarantine or laboratory conditions. Here, the female of P. euphyllurae is redescribed and its male is described and illustrated for the first time; the only previous mention of male P. euphyllurae was from Tunisia, reared from the same psyllid host but without any details on its morphology. A lectotype is designated for Encyrtus euphyllurae Masi. Information is given on the results of genetic matching between the two sexes of the parasitoid and also on the presence of the bacterial Wolbachia symbiont that apparently is affecting reproduction of this species, including its sex ratio in the field. Two species of hyperparasitoids have also emerged from the parasitized olive psylla nymphs from Catalonia: numerous specimens of Apocharips trapezoidea (Hartig) (Hymenoptera, Figitidae) and one specimen of a Pachyneuron sp. (Hymenoptera, Pteromalidae).
Iron in Haemoglobinopathies and Rare Anaemias
Authors: Porter John
Published: January 2015

Iron overload in haemoglobinopathies and rare anaemias may develop from increased iron absorption secondary to hepcidin suppression, and/or from repeated blood transfusions. While the accumulation of body iron load from blood transfusion is inevitable and predictable from the variable rates of transfusion in the different conditions, there are some important differences in the distribution of iron overload and its consequences between these. Transfusion-dependent thalassaemia (TDT) is the best described condition in which transfusional overload occurs. Initially iron loads into macrophages, subsquently hepatocytes, and then the endocrine system including the anterior pituiatry and finally the myocardium. The propensity to extrahepatic iron spread increases with rapid transfusion and with inadequate chelation therapy but there is considerable interpatient and interpopulation variability in this tendency. The conduits though which iron is delivered to tissues is through non transferrin iron species (NTBI) which are taken into liver, endocrine tissues and myocardium through L-type calcium channells and possibly through other channells. Recent work by the MSCIO group1 suggests that levels of NTBI are determined by three mechanisms: (i) increasing with iron overload; (ii) increasing with ineffective erythropoieis; (iii) and decreasing when level of transferrin iron utilisation is high. In TDT all three mechanisms increase NTBI levels because transferrin iron utilisation is suppressed by hypertransfusion. It is hypothesized that the transfusion regimen and target mean Hb may have a key impact on NTBI levels because high transfusion regimes may suppress the ‘sink’ effect of the erythron though decreased clearance of transferrin iron. In sickle cell disease (SCD) without blood transfusion the anaemia results mainly from haemolysis rather than from ineffective erythropoiesis.2 Thus there is a tendency to iron depletion because of urinary iron loss from intrascular haemolysis outweighs any increased iron absortion from hepcidin suppression. These effects result in a low trasferrin saturation and NTBI levels and a low tendency from extrahepatic iron distribution. In rare anaemias that result from low production of red cells such as Diamond Blackfan Anaemia (DBA) there is little or no clearance of transferrin iron by the erythron. This leads to high NTBI and a high tendency to extrahepatic iron distribution in DBA. These differences potentially impact on strategies for monitoring and treatment of iron overload in these different conditions.

Tracking the employee satisfaction-life satisfaction binary: The case of South African academics
Authors: Mafini Chengedzai
Published: January 2015

Orientation: The study tests a conceptual framework that suggests a positive interplay between life satisfaction and five employee satisfaction dimensions, namely workplace flexibility, skills utilisation, teamwork, remuneration and autonomy.Research purpose: The aim of the study was to investigate the relationship between employee satisfaction and life satisfaction amongst university academics in South Africa.Motivation for the study: The study occupies the gap in literature focusing on the interaction between employee satisfaction and life satisfaction amongst South African university academics.Research design, approach and method: A three-section survey questionnaire was administered to 273 academics recruited from three universities in Gauteng, South Africa. After a confirmatory factor analysis, hypotheses were tested using a combination of Kendall’s tau correlation coefficient and regression analysis.Main findings: Correlation tests revealed strong positive relationships between life satisfaction and three factors: workplace flexibility, skills utilisation and autonomy. Regression analysis showed that workplace flexibility, skills utilisation and autonomy were statistically significant.Practical/managerial implications: Research findings could expedite the generation of strategies for meeting the employment needs and expectations of university academics, thereby reducing the shortage of university academics in South Africa.Contributions/value-add: The conceptual framework proposed in this study is a useful tool for conceptualising the relationship between employee satisfaction and life satisfaction in the higher education environment.
Laboratorios artísticos colaborativos. Espacios transfronterizos de producción cultural
Authors: Collados-Alcaide Antonio
Published: January 2015

El emerger del paradigma del código abierto y las demandas de los movimientos sociales han permeabilizado los modos de organización de las instituciones culturales modernas. El artículo analiza el surgimiento de una nueva espacialidad crítica y colaborativa y cómo ésta está transformando los modos de investigación y producción cultural actual. Se centra en presentar el potencial instituyente de las nuevas formas de cooperación que se están ensayando en lo que se define como laboratorios artísticos colaborativos. Espacios de investigación y creación híbridos, fundamentados en estructuras cooperativas y en red, que hacen emerger un nuevo cuerpo socio-técnico que obliga a replantear las condiciones orgánicas tradicionales que han demarcado los escenarios de producción de conocimiento y práctica artística.

Authors: PEREZ PATRÍCIA MARIA PÉRICO , GERMANI ROGÉRIO
Published: January 2015

O objetivo deste trabalho foi estudar as características físicas e químicas da farinha de berinjela pura e em combinação com farinha de trigo. A farinha de berinjela apresentou elevado teor de fibra alimentar total e alta quantidade de proteína, de cinzas e de açúcares totais. Maior concentração de farinha de berinjela em misturas com a farinha de trigo aumentou significativamente os teores de proteína, de sais minerais e de fibra alimentar total das farinhas mistas. O alto teor de fibra alimentar da farinha de berinjela permite apontá-la como alternativa para uso em mistura com farinha de trigo na elaboração de produtos de panificação (biscoitos, pães e massas alimentícias). Maior quantidade de farinha de berinjela na farinha mista amplia a capacidade da mistura em absorver água, podendo aumentar o rendimento da massa em produtos de panificação. A farinha de berinjela é facilmente obtida na granulometria da farinha de trigo, facilitando sua homogeneização. WHEAT AND EGGPLANT MIXED FLOUR: PHYSICAL AND CHEMICAL CHARACTERISTICS Abstract The aim of the present work was to study the physical and chemical characteristics of eggplant flour and its combination with wheat flour. The eggplant flour presented high total dietary fiber content and high protein, ashes and total sugars contents. Higher concentration of eggplant flour in mixtures with wheat flour significantly enhanced protein mineral salts and total dietary fiber content of the mixed flours. The high dietary fiber content of the eggplant flour allows to designate it as utilization alternative in mixture with wheat flour in the elaboration of bakery products (cookies, breads and pasta). Greater quantity of eggplant flour in the mixed flour enlarges the mixture capacity to absorb water, being able to enhance the mass yield in bakery products. The eggplant flour is easily obtained at particle size similar to wheat flour, facilitating its homogenization.
L' agriculture familiale et l' agriculture durable en Amérique du Nord: vers une agriculture "environnementalement correcte"
Authors: Jean Bruno
Published: January 2015

L'auteur analyse les mesures mises en oeuvre aux Etats-Unis et au Canada et qui vont dans le sens de l' auto-responsabilisation des agriculteurs face à la protection de l'environnement et des ressources agricoles renouvelables. L'auteur défend la these que 1'émergence de cette responsabilité environnementale des agriculteurs nord-américains peut donner naissance à une agriculture durable ou "environnementalement correcte" qui se fera dans le cadre du systeme agoalimentaire actuel et qui repose des fermes familiales modemisées. Apres avoir décrit les principales mesures du dispositif agroenvironnemental du Farrn Billaméricain qui met l' accent sur la capacité de "stewarship" des agriculteurs (gestion avisée des terres au sens de "ménagement" comme le disaient Olivier de Serres, un fondateur de 1'agronomie modeme) et dont les mesures canadiennes se font aussi l' écho, I' auteur conclue en montrant que l'agriculture familiale est une forme sociale de production agricole proche du modele théorique de l' agriculture durable.

O patchouli (Pogostemon cablin), pertencente à família Lamiaceae, possui grande interesse comercial pela presença de óleo essencial, contido nas folhas, que é utilizado principalmente na indústria de perfumaria. O objetivo deste trabalho foi avaliar o enraizamento de estacas de patchouli, de acordo com o número de folhas e a região do ramo utilizado para a estaquia. As estacas de patchouli foram obtidas de plantas cultivadas no município de Joinville-SC. Foram instalados dois experimentos com delineamentos experimentais inteiramente casualizados e cinco repetições. No primeiro experimento, foi avaliada a presença de folhas (estacas sem folhas, estacas com uma folha e estacas com duas folhas) usando estacas medianas. No segundo experimento, foi avaliada a posição de coleta das estacas no caule, testando estacas basais, medianas e apicais. As estacas apicais e medianas foram preparadas com um par de folhas e as estacas basais sem folhas. As avaliações foram realizadas aos 30 dias após a estaquia. Estacas apicais e medianas não diferiram entre si, quanto à porcentagem de enraizamento (93,7% e 83,7%, respectivamente) e comprimento médio das três maiores raízes por estaca (11,1 cm e 10,2 cm, respectivamente), sendo superiores em relação às estacas basais. O número de raízes emitidas por estaca decresceu significativamente das estacas apicais (35,5) para as basais (7,3). Estacas com duas folhas e uma folha apresentaram maior porcentagem de enraizamento (71,7% e 51,7%, respectivamente) e de brotação (78,4% e 44,9%, respectivamente) do que as estacas sem folhas. Para o número de raízes emitidas por estaca, aquelas que continham duas folhas (25,7) foram superiores às com uma folha (15,6) e às sem folhas (2,7). Recomenda-se para a propagação por estaquia do patchouli o uso de estacas apicais ou medianas com duas folhas.
