Abstract
It is well known that green algae cells are used for bio-fuel production. There are a few known ways of how to process algae cells for oil extraction – chemical and mechanical. Ultrasonic cavitation is one example of mechanical processing that is in use. Longitudinal ultrasonic systems are used for this purpose. In a proposed system the flow of an algae–liquid mixture is created by means of the ultrasonic capillary effect, thus the transducer is the only energy consumer which now acts as a homogenizer (disruptor) and a pump at the same time. What is important is that the capillary is located nearby the strong cavitation field which decreases the chance of unprocessed algae cells flowing into the secondary reservoir. Numerical and comparative tests are done and presented in this paper. The main results are presented in figures and tables, all advantages of the system are outlined in the conclusion section.

Published: March 2015

BACKGROUND:
Myxoma resistance protein 1 (MxA) is induced during viral infections. MxA testing could be helpful to differentiate between viral and bacterial infections.

METHODS:
A prospective multicenter cohort study was performed in pediatric emergency departments. MxA blood values were measured in children with confirmed viral or bacterial infections, uninfected controls, and infections of unknown origin. First patients were used to determine MxA threshold for viral infection. The diagnostic performance of MxA was determined by using receiver operating characteristic (ROC) analysis. Sensitivities (Se), specificities (Sp), and positive and negative likelihood ratios (LR+, LR–) were calculated.

RESULTS:
The study included 553 children; 44 uninfected controls and 77 confirmed viral infections (mainly respiratory syncytial virus and rotavirus) were used to determine an MxA threshold at 200 ng/mL. In the 193 other patients with confirmed infections and uninfected controls (validation group), MxA was significantly higher in patients with viral than in those with bacterial infections and uninfected controls (P &lt; .0001). The area under the ROC curve (AUC) were 0.98, with 96.4% Se and 85.4% Sp, for differentiating uninfected from virus-infected patients and 0.89, with 96.4% Se and 66.7% Sp, for differentiating bacterial and viral infections. MxA levels were significantly higher in patients with clinically diagnosed viral versus clinically diagnosed bacterial infections (P &lt; .001). Some patients with Streptococcus pneumonia infections had high MxA levels. Additional studies are required to elucidate whether this was due to undiagnosed viral coinfections.

CONCLUSIONS:
MxA is viral infection marker in children, at least with RSV and rotavirus. MxA could improve the management of children with signs of infection.

Authors: Crichton Alison , Knight Sarah , Oakley Ed , Babl Franz E. , Anderson Vicki 
Published: March 2015

BACKGROUND AND OBJECTIVE:Fatigue is common in chronic health conditions in childhood, associated with decreased quality of life and functioning, yet there are limited data to compare assessment instruments across conditions and childhood development. Our objective was to describe fatigue assessment instruments used in children with chronic health conditions and critically appraise the evidence for the measurement properties of identified instruments.METHODS:Data sources included Medline, Cumulative Index to Nursing and Allied Health Literature, and PsycINFO (using the EBSCOhost platform). Study selection included quantitative assessment of fatigue in children with health conditions. Data extraction was as follows: (1) study design, participant and fatigue instruments, (2) measurement properties of fatigue instruments, (3) methodological quality of included studies, and (4) synthesis of the quality of evidence across studies for the measurement properties of fatigue instruments.RESULTS:Twenty fatigue assessment instruments were identified (12 child reports, 7 parent reports, 1 staff report), used in 89 studies. Fatigue was assessed in over 14 health conditions, most commonly in children with cancer and chronic fatigue syndrome. Evidence for the measurement properties of instruments varied, and overall quality was low. Two fatigue instruments demonstrated strong measurement properties for use in children with diverse health conditions and children with cancer.CONCLUSIONS:The review is limited to children younger than 18 years and results are specific to health conditions described, limiting generalizability of findings to other populations. Evidence for the measurement properties of fatigue instruments varied according to the population in which instruments were used and informant. Further evidence is required for assessment of fatigue in younger children, and children with particular health conditions.

Published: March 2015

<p>The Wushan skarn copper deposit is genetically associated with the Wushan granodiorite. In this study, we investigate the petrography and mineralogy of biotites within the Wushan granodiorite. We also determine the formation conditions of these biotites and discuss the significance of these minerals in terms of petrogenesis and mineralization. Electron microprobe analysis shows that biotites within the Wushan granodiorite are Magnesio-biotites that contain relatively high Mg and Ti concentrations and low Fe and Al concentrations. The ionic coefficient of Al<sup>VI</sup> in these biotites ranges from 0.03 to 0.19, with SFeO/(SFeO + MgO) ratios that range from 0.531–0.567 and MgO concentrations that range from 12.80–14.06 wt%. These results indicate that the Wushan granodiorite is an I-type granite. The Wushan biotites crystallized at temperatures (T) of 720°C–750°C, with oxygen fugacity (fO<sub>2</sub>) conditions of –11.6 to –12.5 and pressures (P) of 0.86–1.03 kb. These conditions are indicative of a crystallization depth (H) of 2.84–3.39 km. These data also indicate that the Wushan granodiorite developed under conditions of high temperature and high oxygen fugacity, suggesting that the Wushan granodiorite is prospective for magma-hydrothermal mineralization and that this granodiorite probably contributed to the formation of the Wushan skarn copper deposit.</p><p> </p><p><strong>Resumen</strong></p><p>El depósito de skarn cuprífero de Wushan está asociado genéticamente con la granodiorita de Wushan.

Un análisis de microsonda a electrones muestra que las biotitas de la granodiorita de Wushan son biotitas de magnesio que contienen altas concentracionesrelativas de Mg y Ti y bajas de Fe y Al.

Estas condiciones indican una profundidad de cristalización (H) de 2,84-3,39 kilómetros. Los datos también indican que la granodiorita de Wushan se desarrolló bajo condiciones de alta temperatura y alta fugacidad de oxigeno, lo que sugiere que la granodiorita de Wushan tiene potencial para la mineralización magmática-hidrotérmica y que esta granodiorita probablemente contribuyó a la formación del depósito de skarn cuprífero de Wushan.</p>

Published: March 2015

<p>The compression ratio of Municipal Solid Waste (MSW) is an essential parameter for evaluation of waste settlement. Since it is relatively time-consuming to determine compression ratio from oedometer tests and there exist difficulties associated with working on waste materials, it will be useful to develop models based on waste physical properties. Therefore, present research attempts to develop proper prediction models using ANFIS and ANN models. The compression ratio was modeled as a function of the physical properties of waste including dry unit weight, water content, and biodegradable organic content. A reliable experimental database of oedometer tests, taken from the literature, was employed to train and test the ANN and ANFIS models. The performance of the developed models was investigated according to different statistical criteria (i.e. correlation coefficient, root mean squared error, and mean absolute error) recommended by researchers. The final models have demonstrated the correlation coefficients higher than 90% and low error values; so, they have capability for acceptable prediction of municipal solid waste compression ratio. Furthermore, the values of performance measures obtained for ANN and ANFIS models indicate that the ANFIS model performs better than ANN model.</p><p> </p><p><strong>Resumen</strong></p><p>El índice de compresión de residuos sólidos es un parámetro esencial para la evaluación del asentamiento de un basurero municipal. Debido al desgaste de tiempo para determinar el índice de compresión a partir de pruebas edométricas y debido a las dificultades asociadas al trabajo con materiales desechados es necesario desarrollar modelos basados en las propiedades físicas de los desechos solidos. Además, la presente investigación pretende desarrollar modelos de predicción apropiados a partir de los esquemas ANFIS y ANN. El índice de comprensión se modeló como una función de propiedades físicas de desechos que incluyen el peso seco de una unidad, el contenido de agua y el contenido orgánico biodegradable. De la literatura se tomó una base de datos confiable de pruebas edométricas experimentales que fue empleada para preparar y evaluar los modelos ANFIS y ANN. El desempeño de los modelos desarrollados fue investigado de acuerdo con diferentes criterios estadísticos (por ejemplo, el coeficiente de correlación, el error cuadrático medio y el error medio absoluto) recomendados por investigadores. Los modelos finales han demostrado coeficientes de correlación mayores al 90 por ciento y valores bajos de error. Esto significa que estos modelos tienen una capacidad de predicción aceptable para el índice de comprensión del basurero municipal. Además, los valores de las medidas de desempeño obtenidos para los modelos ANFIS y ANN indican que el modelo ANFIS tiene una mayor asertividad que el modelo ANN.</p><p><strong><br /></strong></p>

We present a species list of the marine cnidarians recorded from the Pakistani waters, north­ern Arabian Sea. It comprises a total of 119 species distributed in 41 families, 14 orders and 4 classes. With 44 species, the order Scleractinia (class Anthozoa) is the best-represented cnidarian taxon. Cnidarians from Pakistan are a poorly studied group which is mentioned in few occasional papers; no new species have been described from the region. The present paper will provide baseline information for future studies in Pakistan.
Temperature Dependent Structure Stability Studies on Thermoelectric Yb0.025Fe0.3Co0.7Sb3

Published: March 2015

ABSTRACTDepending on their application temperature thermoelectric (TE) materials are classified in three main categories; as low (up to 250°C), intermediate (up to 550°C) and high (above 600°C) temperature. Currently, Skutterudites (CoSb3) based materials have shown promising results in the intermediate temperature range (300-500°C). This family of material is highly suitable for automotive, marine transportation and industrial power generation applications to recover the waste heat from the exhaust and generate electricity. Conventional TE modules need p- and n-type semiconductor materials and for the skutterudite family, iron (Fe) has proven to be among the best candidates for the substitution of cobalt sites. Additionally, rare earths are introduced as rattlers in the crystal cages of the skutterudite to decrease the thermal conductivity, thus improving the figure of merit ZT of the TE material. For practical application for device fabrication, stability of these materials is of great importance. Compositional stability is being addressed as the material decomposes above certain temperature. Temperature dependent x-ray diffraction study was performed on Fe substituted, Yb-filled skutterudites, using Beam Line I711 at MAX LAB, to observe the crystal structure as a function of temperature. Diffraction patterns were collected from room temperature up to 500°C by utilizing Huber furnace. The results show success in filling process showing almost 80% reduction of the thermal conductivity from bulk. Additionally the thermal expansion coefficient value was within the average value for skutterudites which proves practical application of this powder for industrial applications.
The Courtyard Inside and Out: a Brief History of an Architectural Ambiguity
Authors: Nelson Robert 
Published: March 2015

Observing several advantages of architecture that incorporates an internal courtyard, this paper traces the history of the motif through the evidence of building archetypes and lexical and literary records. Despite the literal centrality of courtyards to so many traditions of urban construction, the motif proves quite weak in contemporary architecture. The article gives several reasons for this decline in popularity and proposes that the very words used to describe courtyards are partly to blame for the poor traction of this adorable feature. In the process of describing the many historical responses to courtyards, the article conducts a phenomenology of this remarkable 'void' in the middle of a building that has so much social presence.
The Labor-saving Kitchen: Sources for Designs of the Architects' Small Home Service Bureau
Authors: Tucker Lisa M. 
Published: March 2015

The history of the kitchen has received much attention from designers and design historians. Since the writings of Catharine Beecher, designers, household engineers, and others have written about the importance of the kitchen as the center of the home. This research traces the impact of the writings of theorists such as Frederick Taylor, Georgie Boynton Child, Helen Binkerd Young, and Christine Frederick on the designs produced by the architects in the first quarter of the 20th century. Frederick's work took the concept of an efficient kitchen to a new level applying movement studies and introducing new ideas to the kitchen layout and arrangement. In a properly laid out and equipped kitchen, steps were saved by placing kitchen cabinets, ovens and stoves, refrigerators and sinks where they were needed in the sequence of food preparation and delivery to dining table as well as clean up after the meal. In her books, she also provided advice on a variety of considerations, such as appliances and accessories, lighting and ventilation; materials, finishes and color; and appliances and equipment. In 1919 a group of architects dedicated to improving the housing stock in the United States through good design banded together to form the Architects' Small House Service Bureau (ASHSB). Their first plan book, How to Plan Finance and Build your Home published in 1921, also encouraged labor-saving kitchen design and provided advice on kitchen design. The research reported here assesses how the influence of Frederick and Boyton's advice as reflected in the work of and interpreted by Helen Binkerd Young is demonstrated in the kitchen designs of the ASHSB's first plan book. A plan content analysis instrument, developed using Frederick's writings and edited to include other variables from Young and Child, is used to analyze the 99 kitchens and two essays in the ASHSB's plan book. The plans and accompanying comments evidence enthusiasm for the concept of scientific management and other labor- and energy-saving concepts promoted by Frederick. Many of her specific suggestions are incorporated in their kitchen designs, but there is limited evidence that ASHSB designs are only influenced by Frederick but rather include other popular labor-saving concepts of the early 20th century.
Four Ways of Knowing: A Multidisciplinary Approach to Teaching Community-based Design
Authors: Harrison Sally 
Published: March 2015

Design education, especially in an undergraduate course of study, seeks to prepare students for professions and for citizenship in a world they hardly know. The studio typically provides only a surrogate experience in addressing formal and spatial problems, and is limited by time, by its geographic space, and by a dialogue that is more often than not, self-referential. It very rarely engages systemic questions of public policy, or the specific challenges of implementing at full scale ideas that are conceived through representational means. The constrained intellectual context is most poignantly seen in the urban design studios where problems are situated in the real world, and where issues outside the purview of design are found embedded in a place. Form-focused studio exercises that are necessarily a part of beginning architecture education are inadequate for exploring the indeterminacy of urban space and the complexity of human environments. When students enter an urban design studio, especially when they undertake community-based projects, they must take up the mantle of citizenship and engage in an enterprise that is fundamentally relational and grounded in experience. They need more information and more ways of knowing the world than traditionally the design disciplines can offer. This paper presents the outcomes of an experimental neighborhood-based teaching project undertaken as a collaboration among classes in architecture, landscape architecture, urban geography and the fine arts at Temple University. Although initiated through the architecture faculty's desire to enrich its own undergraduate urban design studio, all the collaborators shared our concern about the narrowing effects of disciplinary bracketing on student learning, especially when the goal was to address real world situations. Each discipline brought to the project its particular disciplinary culture -- its language, methodology and areas of concern -- and a shared aspiration to puzzle together these diverse perspectives around questions of making places that are meaningful, humane and sustainable. The struggles and synergies among disciplines were alternatively inspiring, annoying, challenging, rich and imperfect. But intense engagement with a community re-centered the dialogue from inside the academic context to outside, and framed a multidisciplinary way of thought. The community itself proved to be a powerful coalescing agent; the inherent layering of issues in the real-world context made it virtually impossible to remain insensible to interdependencies in life that transcend disciplinary boundaries. Here Richard Sennett's definition of what constitutes a democratic urbanity was applicable. The Greek term for "public”, synkoikismos, means "to bring together in the same place people that need each other but worship different household gods.” (47) This deceptively simple public-making concept became the basis for a process of learning, and a vehicle for working with the larger truths about how cities are formed and experienced.
Applications in Cross-Curriculum Teaching The Synthesis of the Design Studio and Building Technology Seminar

Published: March 2015

"Change or perish. You need to prepare yourself for a profession that you are notgoing to recognize a decade from now.”Thom Mayne, Remarks on building information modeling at the 2005 AIAConvention, Las Vegas, NVToday architects are faced with new challenges involving Integrated Project Delivery and associated digital technologies that are rapidly changing the way architects work. Collaboration is the key to this newway of working as architects discover that the management of buildinginformation requires new skills and methods in design.How do educators respond to this call? How do we prepare a futuregeneration of architects to thrive within a rapidly changing profession?Given these new models for project delivery currently being utilized by theprofession, a new pair of courses was created at the Southern CaliforniaInstitute of Architecture (SCI_Arc) for the integration of the designcurricula with a building technology course by emphasizing teamworkand the use of three-dimensional software. The aim was to develop newskill-sets for students while maintaining a deep understanding of designand built form. Educators have long struggled with traditional architectural curricula that inherently separate design and technology courses. This bifurcation, often times convenient and useful for the organization of aschool and curriculum, is of course at odds with the "comprehensive” nature of architectural education that is so strived for in most programs.This paper serves to show examples of an attempt to address this seriousissue within the first professional graduate school curriculum (3 1/2 yearM.ARCH) by bridging both the second year design and technology classesover a two semester span. The goals of the two courses were; to bridgethe gap between design and technology pedagogy, develop collaborativetools for students, investigate a comprehensive understanding of theintegration of building systems, and to finally produce a set of documentsthat demonstrate this ability and use appropriate three-dimensionalsoftware to facilitate the investigation.It is helpful to set the stage on the importance of this shift of educational methodology by outlining first the context of the current environment bothwithin the profession and the academic realms. Finally, I will attempt toreflect on the methods employed and analyze the pros and cons of theendeavor and discuss possible improvements.
