Full textAbstract:
Background: Malaria is a protozoal disease caused by infection with parasites of Plasmodium species, such as P. vivax, P. falciparum, P. malariae, P. ovale and P. knowlesi through female Anopheles mosquito. Plasmodium vivax alone causes 60 to 65% of infections in India. The main objective of the study was to observe various complications in the patients affected with P. vivax malaria and to analyse the clinical, hematological and biochemical profile of these patients.Methods: A non-randomized prospective study was carried out on 170 patients with acute febrile illness admitted in the department of Medicine, SMS Hospital, Jaipur during period from October 2011 to September 2012 presented The infection was confirmed by detection of parasite (for P. vivax) in peripheral blood film by thick and thin slide methods and rapid diagnostic test (Optimal test).Results: Male preponderance was seen in the study. Death was noted in 5 (3%) patients. Thrombocytopenia (85%) was the most common finding observed. Level of serum creatinine was more than 1.5 mg/dl in 34.7% patients. Thirty-one patients (18.23%) had severe anaemia (Hb <6 gm/dl). Severe hypoglycemia was observed in 19 patients (<40-60 mg/dl). Acute renal failure was common comorbidity observed in majority of the patients. Mean LDH value was significantly higher in patients with hepatitis and anemia.Conclusions: The clinical pattern of P. vivax monoinfection has changed recently. Every patient of P. vivax malaria should be evaluated thoroughly for clinical or biochemical evidence of any complications and patients presenting with complications should managed as per guidelines of severe malaria.

Background.Malaria and typhoid fever are major public health problems in tropical and subtropical countries. People in endemic areas are at risk of contracting both infections concurrently.Objectives.The study was aimed at determining the prevalence and associated risk factors of malaria, typhoid, and their coinfection among febrile patients.Methods.A cross-sectional study was conducted on 200 febrile patients suspected for malaria and/or typhoid fever from April to May, 2013, at Ayinba Health Center, Northwest Ethiopia. Blood samples were collected for blood culture, Widal test, and blood film preparation. Data were analyzed using SPSS version 20 statistical software.Results.The prevalence of malaria was 36.5% (n=73). Among these 32 (43.8%), 30 (41.1%) and 11 (15.1%) were positive forP. falciparum, P. vivax,and mixed infections, respectively. The seroprevalence of typhoid fever was 38 (19%), but 1 (0.5%) with blood culture. Malaria typhoid fever coinfection was 13 (6.5%). 2–5-year-old children and poor hand washing habit were significantly associated with malaria and typhoid infection, respectively (P<0.05).Conclusions.The prevalence of malaria and typhoid fever was found high. Further studies should be done on the other determinants of malaria and typhoid fever coinfection in different seasons and different study areas.

Full textAbstract:
Background. Malaria is a mosquito-borne infectious disease known to cause significant numbers of morbidities and mortalities across the globe. In Ethiopia, its transmission is generally seasonal and highly unstable due to variations in topography and rainfall patterns. Studying the trends in malaria in different setups is crucial for area-specific evidence-based interventions, informed decisions, and to track the effectiveness of malaria control programs. The trend in malaria infections in the area has not been documented. Hence, this study aimed to assess the five-year trend in microscopically confirmed malaria cases in Dembecha Health Center, West Gojjam Zone, Amhara national regional state, Ethiopia. Methods. A health facility-based retrospective study was conducted in Dembecha Health Center from February to April 2018. All microscopically confirmed malaria cases registered between 2011/12 and 2015/16 were carefully reviewed from laboratory record books and analyzed accordingly. Results. A total of 12,766 blood films were requested over the last five years at Dembecha Health Center. The number of microscopically confirmed malaria cases was 2086 (16.34%). The result showed a fluctuating yet declining trend in malaria infections. The highest number of cases was registered in 2012/13, while the lowest was in 2015/16. Males and age groups >20 constituted 58.9% and 44.2% of the patients, respectively, being the hardest hit by malaria in the area. Malaria existed in almost every month and seasons. Plasmodium falciparum was the predominant species. The highest peak of malaria infections was observed in the late transition (October-December) 799 (38.3%) and early transition (May-June) 589 (28.2%) seasons. Conclusion. Although the results indicate a fluctuating yet declining trend, the prevalence of confirmed malaria cases in the area remains alarming and indicates a major public health burden. Therefore, close monitoring and intervention measures to control malaria infections in the area and also to tackle the dominant species, Plasmodium falciparum, are necessitated accordingly.

Full textAbstract:
ABSTRACTEleven ancient Chinese ceramics from the early Bronze Age Qijia culture (c. 2200 – 1600 BCE) in the collection of the Harvard Art Museums were the subject of an interdisciplinary research project to explore questions about manufacturing techniques, specifically details of formation and decoration. While the Qijia culture, centered in the Gansu and Qinghai provinces of northwest China, is historically important as one of the earliest metalworking cultures of China and as a center of intercultural communication between China and central Asia, detailed scholarship about the culture is still emerging. Qijia ceramics have been categorized by typology, but little has been done regarding methods of manufacture. This study used visual examination and digital X-radiography to investigate ceramic production, especially the use of a wheel. In addition, the ceramic paste, including natural inclusions and temper, was examined. While film radiography has often been used to study ceramics, digital radiography presented new capabilities as well as challenges. Experimentation through the making of test vessels and tiles at the Harvard Ceramics Program provided additional insights into Qijia ceramics’ manufacture and surface decoration techniques, often described as cord-impressed.

Full textAbstract:
With the increase in urbanization, intraurban residential mobility, which underlies urban growth and spatial restructuring, is gradually becoming an integral part of migration in China. However, little is known about the differences in residential mobility between locals and migrants, especially in urban areas in Northwest China. In this study, we aimed to fill this void by investigating the residential mobility patterns among Urumqi’s locals and migrants based on data from a survey and face-to-face interviews that were conducted in 2018. The results first show that the migrants with low homeownership rates relocated more frequently, but had less intentions to move within Urumqi, compared with the locals. A larger proportion of migrants than locals was forced to migrate. Evidence also suggests that the migration directions of locals and migrants differ: both locals and migrants tended to relocate from the southern areas, like Tianshan and Saybark Districts, to northern areas, like Xinshi and Midong Districts, which show the northward migration process of the urban population center in Urumqi. In contrast to the locals, whose net migration direction was from marginal areas to the central area, the net migration direction of migrants was from the central area to the marginal areas, contributing to the formation of migrant communities in the suburbs and spatial segregation between locals and migrants. Lastly, the locals’ intentions to move were widely influenced by age, ethnic group, type of employment, family population, housing area, and residential satisfaction; the migrants’ mobility intentions were mainly influenced by housing type and residential satisfaction. To attract more migrants to the urban areas in Northwest China, a more relaxed migrants’ household registration policy should be implemented, and the inequalities of the social security system and housing system between migrants and locals should be reduced to bridge the gap between migrants and locals.

Full textAbstract:
Background In Ethiopia, anti-malaria treatment is initiated after parasitological confirmation using blood film microscopy at health centers and hospitals, or serological rapid diagnostic tests at health posts. At health posts, the diagnosis is performed by health extension workers using rapid diagnostic tests after little training. However, there is paucity of data about the health extension workers’ performance on rapid diagnostic tests. Hence, periodic monitoring of the performances of health extension workers on malaria rapid diagnostic tests and predicted factors plays a pivotal role for the control of malaria. Methods A cross sectional study was conducted in May 2020, among 75 health extension workers working at health posts in Bahir Dar Zuria district, Northwest Ethiopia. Their performance on malaria rapid diagnostic tests was assessed by distributing known positive and negative samples as confirmed by investigators using both rapid diagnostic test and blood film microscopy. Test results from health extension workers were then compared with that of investigators. Procedural errors committed while performing the tests were assessed using observational checklist. Data were analyzed using SPSS software version 20. Results The overall sensitivity and specificity of health extension workers in detecting Plasmodium species were 96.8% and 98.7%, respectively with 97.3% result agreement between the health extension workers and investigators (kappa value = 0.949). The most common procedural errors committed by health extension workers was ‘not checking expiry date of the test kits’ followed by ‘not adhering to the appropriate time of reading results’ that 70.7% and 64% of the participants committed these errors, respectively. Total number of procedural errors committed by those who have got in-service training was decreased by 47.3% as compared to those without in-service training. Conclusions Health extension workers had high performance on malaria rapid diagnostic tests. However, in-service training and periodic supervision should be given in order to maximize performance on these tests.

Full textAbstract:
Two years after Dutch émigré Andries Deinum was fired from the University of Southern California in 1955 for refusing to cooperate with the House Un-American Activities Committee, he moved to Portland, Oregon to teach film courses through the Portland Extension Center. By 1969 he had become integral to the local film community and had formed Portland State University's Center for the Moving Image (CMI), where he and Tom Taylor taught film history, criticism, and production for the next thirteen years. Although CMI was eliminated in 1981 as part of PSU's financial exigency, CMI's teachers and students have been a vital part of the thriving film community in Portland since its foundation. A key former student and figure in Portland's film community, Dr. Brooke Jacobson credits Deinum, Taylor, and CMI for laying the foundation for the Northwest Film Center (co-founded by Jacobson in 1971 as the Northwest Film Study Center). Through archival research and oral history methodology, this thesis pieces together Andries Deinum's role in the development of film education in the United States and the mark he left on Portland's cultural landscape, specifically the city's vital and thriving cinematic community.

This chapter surveys a breadth of approaches to the ethics of film and other narrative media, both contemporary and historic, and positions them in relation to developments in cognitive media ethics. These include cine-ethics and film philosophy, phenomenological approaches, literary ethics and hermeneutics, notions of aesthetic autonomy, and ethics in narratology. The contributions and challenges of each approach are summarized, as are their uses in the development of a normative ethics for cognitive media studies. Throughout this chapter, a case emerges for the complementary, elaborative rigors of cognitive science, normative ethics, and consequentialism. The chapter concludes by indicating how methods for analysis developed at the center of these areas of study will inform the remainder of the book.

Full textAbstract:
In the art of cinema, which fulfills the function of a “dream factory” with its male-dominated narrative structure, men are represented in active roles with their actions, while women in passive roles that do not or cannot interfere with the flow of events with their inactions. This perception, which dominates the cinema, showed a change with the reflection of intellectual context of the Second Wave Feminism to the films. In this sense, in the study, Fried Green Tomatoes, regarded as a feminist film example by movie critics and directed by Jon Avnet in 1991, was chosen as a sample. In the study, structuralist narrative codes that construct meaning in the film are analyzed in the context of feminist thought and film theory paradigms. In the film, the “strong female character representations,” which are placed in the center of narrative and positioned to advance the story, are subjected in the foreground; these characters also stand against the known stereotyped roles imposed on women by traditional narrative cinema.

This film shows the immigrants' situation and hopelessness as distinct from the other films (by Umut Dag and Hüseyin Tabak). The film by Kenan Kiliç presents immigrants' alienation in their post-migration processes and emphasizes the phenomenon of not belonging to their own culture. The film departs from a binary opposition and makes a reference on one hand to people's alienation and their relations, and consequently to the power, center-periphery relations while referring to social problems such as immigration, moving up into a higher class, financial troubles and unemployment on the other hand. It is clearly from this research that as a result of migration, consumerism, technology and the culture generated by a new society, immigrants become estranged with each other and the society.

In this chapter, the science fiction anime that takes its source from Masamune Shirow's manga with the same name, Kōkaku Kidōtai (攻殻機動隊, Ghost in the Shell), is examined and compared with the U.S. adaptation film Ghost in the Shell (2017) within the framework of techno-orientalism. The study aims a comparative critique through anime and film, which both allow explaining the transformative potential-effects of technology in a socio-cultural context in the east-west axis, through dissociations, convergences, and integration. It is to review the representations of traditional Western-centered thought that is deconstructed with the narrative which maintains focus on technology axis; it is aimed to reveal with the analysis that takes the 2017 film to the center. In this way, Ghost in the Shell offers possibilities of representation in the axis of futuristic Eastern culture with the female-cyborg character that presents the cyber-society environment, the deconstruction of the idea that puts focus on anthropocentrism, especially the ‘Western man'.

Full textAbstract:
Port-centric logistics clusters are considered as intermodal gateways and/or hubs of international trade, which connect national economies with global production networks. These clusters are spatial agglomeration of logistics related interconnected and interdependent companies. Singapore, Dubai and Rotterdam are world class exemplary of port-centric logistics clusters. The formation of these clusters is a derivative of conducive business environment generated within a geographically defined area. Despite the recognition of port-centric approach to economic development there is insufficient evidence to empirically assess the functional and spatial characteristics of port centric logistics clusters. There is also disagreement on three key questions: how port-centric logistics clusters are defined and identified, what industry types do they constitute and what methods are appropriate to delineate the boundary of port centric logistics cluster. In this paper, a spatial approach is adopted to geographically delineate the spatial congregation of port-centric logistics employment using three major container ports in Australia. Using the Census data from the Australian Bureau of Statistics (ABS 2006), analysis has been conducted on employment data containing information about where people work and what industry they work within the close vicinity of case study seaports. The results show that the spatial extent Australian port centric logistics clusters, which tend to vary both in size and shape. Overall size of employment in port-related industries in Australia has grown substantially. Road freight is dominating industry in the port-centric logistics cluster with a contribution of 23.02% and 37.54% in 2001 and 2006 respectively. The range of port-centric logistics cluster in Melbourne is towards western suburbs and in Botany Bay the port-centric logistics cluster is discerned mainly around eastern suburbs and in Brisbane the spread of port-centred logistics cluster is towards southeast inner Brisbane and Northwest Inner Brisbane suburbs. This shows the impact of land use consolidation by the State Government in their effort to boost transport and warehousing employment closer to Australian container ports. The establishment of port-centric logistics clusters, we argue, could mean the opportunities for organisations to achieve agglomeration economies, increase rivalry among organizations to promote competition, access to greater pool of customers, availability of skilled labour force, closer proximity between customers and supplier, sharing of public infrastructure and resources, increased inter-firm interactions, and knowledge spill-over.

The film technicians who used and managed the technology within the Hollywood studios themselves, such as cameramen and electricians, take center stage in this chapter, focusing on how the technical work of motion picture production was understood, managed, and promoted within the new “factory” system of Hollywood. The primary case study here is the cameramen, who used their organization, the American Society of Cinematographers, and its publication, American Cinematographer, to establish their status as the chief technicians in motion picture production in the silent period, often by resisting unionization and by touting their special knowledge of the tools of the trade. The cinematographers positioned themselves as “engineers” within the studio, a position that the incursion of trained sound engineers into Hollywood challenged.

Full textAbstract:
Chapter Three compares and contrasts the psychotic realism of Psycho and American Psycho to the financial realism of more contemporary finance fictions such as Alger’s The Darlings. The case-study in this chapter is Robert Harris’ science-fiction thriller The Fear Index. While The Fear Index continues the finance novel’s theme of psychosis—its main character, a finance man, is suggested to be psychotic and the novel includes a murder scene set in a hotel shower that is clearly inter-textual with Hitchcock’s film. The novel also resists this theme by refusing to blame everything that is happening to its main character on psychosis. Instead, it gradually reveals that the source of the evils narrated in the book is a trading algorithm that has gone rogue. The Fear Index thus introduces its readers to the contemporary economy of algorithmic, high-frequency trading—a reality that, while it may sound like science fiction, is represented in the novel in a realist, and at one point even documentary-like, mode. Generally received as a sci-fi thriller, The Fear Index thus presents an important step forward in relation to the psychotic realism of American Psycho in that it resists what Joseph Vogl in his philosophical study of the economy has called “the spectralization of capital.” The economy is certainly not forgotten in Harris’ novel but instead takes center-stage.

Full textAbstract:
A concept for mitigating the adverse effects of jet vorticity and lift-off at high blowing ratios for turbine film cooling flows has been developed and studied at NASA Glenn Research Center. This “anti-vortex” film cooling concept proposes the addition of two branched holes from each primary hole in order to produce a vorticity counter to the detrimental kidney vortices from the main jet. These vortices typically entrain hot freestream gas and are associated with jet separation from the turbine blade surface. The anti-vortex design is unique in that it requires only easily machinable round holes, unlike shaped film cooling holes and other advanced concepts. The anti-vortex film cooling hole concept has been modeled computationally for a single row of 30 degree angled holes on a flat surface using the 3D Navier-Stokes solver Glenn-HT. A modification of the anti-vortex concept whereby the branched holes exit adjacent to the main hole has been studied computationally for blowing ratios of 1.0 and 2.0 and at density ratios of 1.0 and 2.0. This modified concept was selected because it has shown the most promise in recent experimental studies. The computational results show that the modified design improves the film cooling effectiveness relative to the round hole baseline and previous anti-vortex cases, in confirmation of the experimental studies.

Full textAbstract:
Film cooling performance of the double-wave trench was numerically studied to improve the film cooling characteristics. Double-wave trench was formed by changing the leading edge and trailing edge of transverse trench into cosine wave. The film cooling characteristics of transverse trench and double-wave trench were numerically studied using Reynolds Averaged Navier Stokes (RANS) simulations with realizable k-ε turbulence model and enhanced wall treatment. The film cooling effectiveness and heat transfer coefficient of double-wave trench at different trench width (W = 0.8D, 1.4D, 2.1D) conditions are investigated, and the distribution of temperature field and flow field were analyzed. The results show that double-wave trench effectively improves the film cooling effectiveness and the uniformity of jet at the downstream wall of the trench. The span-wise averaged film cooling effectiveness of the double-wave trench model increases 20–63% comparing with that of the transverse trench at high blowing ratio. The anti-counter-rotating vortices which can press the film on near-wall are formed at the downstream wall of the double-wave trench. With the double-wave trench width decreasing, the film cooling effectiveness gradually reduces at the hole center-line region of the downstream trench. With the increase of the blowing ratio, the span-wise averaged heat transfer coefficient increases. The span-wise averaged heat transfer coefficient of the double-wave trench with 0.8D and 2.1D trench width is higher than that of the double-wave trench with 1.4D trench width at the high blowing ratio conditions.

Researchers at NASA Glenn Research Center have developed and investigated a novel film cooling design, the anti-vortex hole (AVH), which has been shown to cancel or counter the vorticity generated by conventional holes and increase film effectiveness at high blowing ratios and low turbulence levels. This paper presents preliminary CFD results on the film effectiveness and net heat flux reduction at high blowing ratio and elevated freestream turbulence levels for the adjacent AVH. Baseline cases at low turbulence levels of 5% intensity and length scale of Λx/dm = 1 with a nominal blowing ratio of 2 and a density ratios of 1 and 2 were compared to previous results reported by Heidmann [1]. Higher freestream turbulence cases were investigated with a turbulence intensity and length scale of 10% and Λx/dm = 1 and 3, respectively. Results showed that higher freestream turbulence improves adiabatic effectiveness for the AVH design.

Full textAbstract:
Edge-defined Film-fed Growth (EFG) is a promising technology for production of silicon wafers with minimum loss of silicon material for photovoltaic applications. The growth of the hollow tubes by the EFG method is a very high temperature gradient along the direction of tube growth at the melt-solid interface. As this high temperature gradient is necessary to sustain the high speed of silicon growth through dissipating latent heat at the melt-solid interface, it generates substantial amount of thermal stresses that are associated with defect generation and deformation of the structure. With increase of the tube diameter and reduction of wall thickness, the large thermal stresses lead to significant buckling of the tube. In this study, the buckling behavior of the growing silicon tube is studied experimentally by monitoring deflection of two pairs of opposite faces of an octagonal tube during the growth. Four capacitance sensors were placed on a fixed plane normal to the translation of the tube to measure the varying thickness of the air between the sensor and the tube surface throughout the tube growth. The recorded data reveal the buckling behavior of tubes for several growth runs. Despite the different growth conditions in the EFG systems, similar patterns of buckling behavior have been observed in octagonal silicon tubes with face width of 12.5 cm. A typical buckling pattern observed can be divided into three distinctively different stages, namely seed holder-influenced stage, tube growth stage, and a random fluctuation stage. Each stage has different amplitude of deflection and covers different length of the tube. More interestingly, the recorded surface deflection reveals the displacement of the center of the tube, suggesting off-centered growth and possible instability of the meniscus. It is considered that these mechanisms may contribute to the special buckling pattern observed during growth.

Full textAbstract:
A flat plate test section was used to study how surface roughness representative of an in-service turbine affects the film cooling adiabatic effectiveness and heat transfer coefficient for a round hole geometry. The injection was from a single row of round film cooling holes with injection angle of 30°. The density ratio of the injectant to the mainstream was 2.0 for the adiabatic effectiveness tests, and 1.0 for the heat transfer coefficient tests. A range of momentum flux ratios was examined to characterize the adiabatic effectiveness and heat transfer performance. Streamwise distributions of adiabatic effectiveness and heat transfer coefficients were obtained along the hole center line, and lateral distributions extending to halfway between hole centerlines were obtained at selected streamwise locations to 90 hole diameters downstream. Two rough surfaces with a factor of two difference in roughness levels were compared to an aerodynamically smooth surface. Both rough surfaces degraded the film cooling effectiveness with increasing degradation farther downstream. Degradation of film cooling effectiveness was greater at low momentum flux ratios. At momentum flux ratios high enough so that the cooling jets completely detached from the surface, the rough surfaces slightly increased adiabatic effectiveness in some cases. There was little difference in the effectiveness results between the two rough surfaces. Film cooling injection had little effect on heat transfer rates for any of the surfaces.

Full textAbstract:
Experimental and numerical results are presented for evaporative heat transfer from ten-micron square open-top channels. The radial channels are fabricated in epoxy photoresist on a two micron thick silicon membrane. The working fluid is pumped by capillary forces from a reservoir at the edge of the silicon membrane into the channels where it evaporates. The electrical power dissipated in a thin-film heater in the center of the membrane, the conduction heat transfer rate radially out of the membrane, and the rate of evaporation of the working fluid are measured. A three-dimensional finite difference, time-domain integration is used to predict sensible and latent heat transfer rates. Only 5-10% of the energy dissipated as heat in the thin film heater is carried away as latent heat by the evaporating working fluid. Computed temperatures and heat transfer rates are shown to match the experimental results.

This study models the internal fluid flow from the center to the edge of a rotary atomizer wheel, the flow out of the atomizer, including the film, rivulet and ligament formation, as well as the subsequent atomization process associated with the atomizer outflow using computational fluid dynamics with a volume of fluid approach. The model shows how fluid exits through the overflow and not through the bushing at high inlet fluxes and can reproduce experimental results of power consumption. Furthermore, the drop-size distribution at a given distance from the bushing exit is in good agreement with experimental results.

Full textAbstract:
In this study, the effects of impingement with various configurations at different aerothermal conditions on film cooling are investigated. The detailed adiabatic film cooling effectiveness distributions are obtained by solving steady three dimensional Reynolds-averaged Navier-Stokes equations with SST k-ω turbulence model closure. The influence of impingement on film cooling effectiveness is revealed by comparing the results from two cases: one where coolant is directly fed from a plenum (baseline case) and the other where the film coolant is extracted from the post-impingement flow on spherical dimples. For the latter case with post-impingement flow, the variations of the jet impingement configurations are considered at separation distances (H/Dj) from jet plate to target surface of 1, 2, 4 and 6, and eccentricities (F/Dj) between dimple center and film hole center of 0, 2, and 4. Besides, the effects of target wall heating the post-impingement flow on the external adiabatic film cooling performance are examined. The temperature ratios of the target surface to main flow at the inlet are set at 0.6, 0.7 and 0.8. The results are presented for four various averaged jet Reynolds numbers, which correspond to blowing ratios ranging from 0.5 to 2.0. It is observed that the impingement through the jet plate brings out pressure re-distributions on the target plate with film holes, and the dominant effect is on the flow structures in the supply chamber and near the entrance of the film hole. At the lowest blowing ratio of 0.5, film cooling with post-impingement air on dimples is reduced in comparison with the baseline case, while at higher blowing ratios, the effect of the impingement configuration on film cooling all depends on the flow conditions. In addition, the heating effect of target wall on the post-impingement flow could lower the coolant-to-mainstream density ratio, and then reduces the adiabatic film cooling performance.

Full textAbstract:
The present study numerically investigates the effectiveness of film cooling on a turbine blade leading-edge model through a single-hole coolant exit. The model used in this study has the same dimensions as that of an experimental investigation done earlier by Ekkad et al [1]. The cylindrical model, a half cylinder and a flat after-body attached to it, well represents the leading edge of a turbine blade. The half-cylinder is 88.9 mm in diameter with a length of 364 mm. The flat after-body is attached to it to constitute the model of a turbine blade leading edge. The coolant hole is situated approximately at the center of the cylindrical model along the spanwise direction. The coolant hole makes an angle of 21.5 degrees to the true leading edge and 20 degrees to the spanwise direction. A multi-block grid is generated using GridGen, and the flow is simulated using the flow solver Fluent. The highly clustered structured C-grid is developed around the leading edge of the model with an initial Δy corresponding to a y+ value of 1 and a growth ratio of 1.1 till 10d from the surface. The outer unstructured domain imitates the wind-tunnel as used in the experimental study of Ekkad et al. [1], and the leading-edge model is placed at the center of the domain. Simulations are carried out for different blowing ratios M, ranging from 0.25 to 1.0, with the k-ε realizable turbulence model and κ-ω SST model. The flow is assumed to have a free-stream turbulence intensity of 0.75%. Additionally, the enhanced wall function approach is used as the near-wall treatment in the computational model for the simulation with k-ε realizable turbulence model. Results obtained indicate an increased film-effectiveness for low blowing ratio in the far downstream region. Also, in the vicinity of coolant jet exit, it is observed that increase in blowing ratio increases the film cooling effectiveness.

The 2007 US EPA report to Congress (US EPA, 2007) on the state of energy consumption in data centers brought to light the true energy inefficiencies built into today’s data centers. Marquez et al. (2008) conducted an initial analysis on the productivity of a Pacific Northwest National Lab computer using The Green Grid’s Data Center Energy Productivity metric (The Green Grid, 2008). Their study highlights how the Top500 ranking of computers disguises the serious energy inefficiency of today’s High Performance Computing data centers. In the rapidly expanding Cloud Computing space, the race will be won by the providers that deliver the lowest cost of computing — such cost is heavily influenced by the operational costs incurred by data centers. As a means to address the urgent need to lower the cost of computing, solution providers have been intensely focusing on real-time monitoring, visualization, and control/management of data centers. The monitoring aspect involves the widespread use of networks of sensors that are used to monitor key data center environmental variables such as temperature, relative humidity, air flow rate, pressure, and energy consumption. Such data is then used to visualize and analyze data center problem areas (e.g., hotspots), which is then followed by control/management actions designed to alleviate such problem areas. The authors have been researching the operational benefits of a network of sensors tied in to a software package that uses the data to visualize, analyze, and control/manage the data center cooling system and IT Equipment for maximum operational efficiency. The research is being conducted in a corporate production data center that is networked in to the authors’ company’s global network of data centers. Results will be presented that highlight the operational benefits that are realizable through real-time monitoring and visualization.

This report describes the results of technical analysis, field tests, and laboratory tests that were performed for LED highway lighting options by the Energy Efficiency and Reliability Center (EERC) at Purdue University Northwest for the Indiana Department of Transportation (INDOT). This effort was conducted over the past 3 years to evaluate and test the technology and viability of using modern highway lighting technology to enhance energy efficiency, safety, security, and economic development of communities and roadways. During the testing period there was a continuous discussion between INDOT and EERC regarding the laboratory and field testing of INDOT approved luminaires submitted by vendors. There were multiple discussions with INDOT and vendors regarding the individual details and issues for the 29 luminaires that were tested. A comparison study was conducted by EERC of the various alternatives and comparison to currently installed luminaires. Data was collected for field tests of the luminaires by EERC and INDOT personnel for the luminaires. Field data was evaluated and compared to lighting models using vendor supplied ies data files. Multiple presentations were made at 3 separate Purdue Road Schools regarding the results and procedures of the testing program by EERC in conjunction with INDOT. A total of 22 final reports, considered confidential by INDOT, for individual vendor luminaires have been prepared as part of this effort. These reports were submitted sequentially to INDOT as testing was completed during the course of this effort. A total of 29 luminaires were tested. Some luminaire testing was terminated during testing due to design issues or vendor requests. All testing was summarized in the INDOT specification sheet attached to each report. Observations regarding the consistency of the supplied test luminaire with the requirements of Section 7.2 of the INDOT test procedure “Procedure for evaluation and approval list requirements for solid state ballasted luminaires ITM 957-17P” is provided in the Appendix to the report for each luminaire. Details regarding how these tests were performed and the respective associated evaluation of performance and reliability are provided in the report. This effort included: consideration of published and vendor information; appraisal of products consistent with national industry standards; review of physical design, thermal performance; laboratory testing of photopic performance, reliability, life cycle data and characteristics, and power characteristics; technical and probabilistic risk studies; and field testing and analysis of LED light sources including comparison to currently installed conventional light sources. Assistance in preparing INDOT standards for highway lighting was provided on multiple occasions.
