Меритократия (пер. с англ. Н. Микшиной)
Authors: Judt Tony
Published: September 2015

Тони Джадт (1948–2010) — известный британский философ, интеллектуал, специалист по новейшей истории европейских стран. Профессор Нью-Йоркского университета, директор-учредитель Института Ремарка, одна из главных целей которого — способствовать сближению между американцами и европейцами. В 1996 г. Джадт стал членом Американской академии наук и искусств. В 2008 г. получил европейскую премию за книгу «После войны», посвященную политическим и духовным процессам в послевоенной Европе. В 2009 г. он получил премию Оруэлла «за беспримерный вклад в развитие британской политической мысли». Тони Джадт — автор книг Identity politics in a multilingual age (2004); Postwar: A history of Europe since 1945 (2005); Reappraisals: Reflections on the identity politics (2008). О чем бы ни писал Джадт, во всех его работах присутствует одна из ключевых тем: сложные конфликты и парадоксы европейской истории, которые стали еще острее и поставили новые проблемы после 1989 г. По мысли Джадта, их можно решать только сообща, в содружестве Восточной, Западной Европы и России. Джадт создал целую школу, воспитал молодых исследователей. Его ученики вспоминают Джадта как одного из самых любимых, культовых преподавателей, внимательного и требовательного, одаренного лектора, способного увлечь даже самых равнодушных.Мы публикуем мемуарный очерк покойного историка. Сегодняшний читатель найдет в нем бесценный опыт точного самоанализа, объясняющий непростой путь в науку. Это последний текст ученого, написанный им, вернее записанный и расшифрованный его помощником, когда Джадт уже не мог двигаться, когда с каждым днем сужалось пространство его жизни, но оставалось одно — мысль, работающая по-прежнему ясно и бесперебойно. Материал опубликован через неделю после смерти Джадта в августовском номере журнала The New York Review of Books, с которым профессор Тони Джадт постоянно сотрудничал без малого четыре десятилетия.

Efficiency of Steam-Over-Solvent-Injection-in-Fractured-Reservoirs (SOS-FR) Method Considering Oil Recovery and Solvent Retrieval: Core-Scale Experimentation
Authors: Mohammed M. Almojtaba , Babadagli Tayfun
Published: September 2015

Sole injection of steam or solvent into heterogeneous reservoirs usually yields an inefficient recovery performance. The steam-over-solvent-injection-in-fractured-reservoirs (SOS-FR) method was suggested as a solution to improve the efficiency of heavy-oil/bitumen recovery from fractured carbonates and oil-sands reservoirs after cold production (Al-Bahlani and Babadagli 2008). The method consists of three phases: Phase 1, where steam is injected at low temperatures to heat the matrix and condition the oil for subsequent solvent injection; Phase 2, when solvent-injection dilutes matrix oil by diffusion and enhances gravity-drainage recovery rate; and Phase 3, when low-temperature (at approximately the boiling point of solvent) steam injection retrieves the solvent diffused into matrix.

Previous research was focused on the effectiveness of Phases 1 and 2 of the method (Al-Bahlani and Babadagli 2009a, b), and positive responses were reported at the field scale (Al-Bahlani and Babadagli 2010) with high ultimate recoveries. The efficiency of this process, however, is determined purely by the amount of solvent retrieved at the end of the process. This paper, therefore, focuses on Phase 3, which is performed mainly for solvent retrieval (additional oil is also produced during this phase). Twenty-two static core experiments were performed on water- and oil-wet sandstone and limestone. After saturating the rock samples with different heavy oils, they were immersed into different liquid solvents--hexane, heptane, decane, and diluent oil. Diluent oil used in this study is a distillate that was obtained from a heavy-oil-upgrading unit in Canada. Once the ultimate recovery was achieved by diffusion and gravity drainage (Phase 2), the samples were exposed to different temperatures of hot water (Phase 3) and the amount of solvent retrieved was measured through volumetric and weight measurements and refractometer readings. The retrieval of solvent diffused into matrix was caused mainly by two reasons: (1) evaporation of solvent at elevated temperature and (2) imbibition of hot water into rock (if oil-wet samples become more water-wet during Phase 2).

The amount of solvent retrieved through these processes was determined, and the efficiencies were analyzed for different parameters, including rock wettability, oil viscosity, solvent type, solvent-soaking period, rock type, boundary conditions, different combinations of steam/solvent cycle, and temperature applied.
Tight Cardium Multistage-Fractured Horizontal-Oil-Well-Performance Study Focusing on the Effectiveness of Various Fracture-Fluid Systems
Authors: Reynolds Murray , Moscoso Krefthelle , Buendia Juliana , Gallup Michael
Published: September 2015

In recent years, the tight Cardium sandstones of west central Alberta have observed significant new development with the application of multistage-fractured horizontal wells (MFHWs). This case study reviews the completion costs, economics, and production performance of 148 horizontal oil wells completed in the Pembina field halo areas (west and east), central Pembina, Willesden Green, and Garrington fields.

Production analysis was performed on all wells using the Duong decline-curve-analysis technique. This technique has been used successfully on tight multistage-fractured wells in other areas, and has proved successful at predicting long-term well performance and recoveries. Wells were chosen for comparison that were in the same geological and pressure regions, had a minimum of 2 years of production information, and were stimulated with various fracture-fluid systems.

In one of the analyzed areas, a definite trend was identified; it was found that wells drilled in a certain orientation performed better than wells drilled with other orientations.

Completions and hydraulic-fracturing costs were gathered from public sources in order to understand the cost differences between areas and types of fracture-fluid systems. Using decline curves and cost information, full-cycle economics were run on the ’average’ well for each area in order to determine the net present value (NPV) of each area.

This case study shows there is value in optimizing fracture designs through look-back studies, and there is a need to focus on more-effective fracture-treatment designs in unconventional oil development. The overall results of the study showed: (1) the choice of fracture-fluid system is a key component in optimizing economics in the Cardium halo areas; and (2) the optimum fluid system varies in different areas of the Cardium.
Benchmarking the Supercomputer Trace 7/200
Authors: O'Donnell J. J. , Campbell C. L. , Chase C. A. , Woo P. T.
Published: September 2015

The supercomputer Multi flow TRACE 7/200 was benchmarked with a compositional simulation model. For comparison, the model was also run on the CRAY X-MP/12, the CONVEX C-l XP, and the ALLIANT FX/8-8. The performance of the computer was judged in terms of CPU time and main memory requirements.

The Multiflow system uses the very long instruction word (VLIW) architecture. The instruction word can be as wide as 1,024 bits. It is packed with up to 28 primitive machine operations, which are executed in overlapped fashion. Thus, many different operations such as load, store, add, multiply, etc. may be executed simultaneously in one clock cycle.

The entrance level Multi flow system is the TRACE 7/200. It has a cycle time of 130 ns. Up to 7 operations may be executed on the 7/200 per instruction, resulting in 53 MIPs and 60 MFLOPs.

The object code for the Multi flow system is generated by the trace-scheduling compacting compiler. In addition to generating the compacted instructions for the VLIW, the computer predicts branch paths and prepares compensation codes to guarantee correct branching. The amount of compensation codes must be small in order not to degrade computing efficiency.

The reservoir model was an expanded version of the gas cycling model in the Third SPE Comparative Solution Project. It was derived by repeating the SPE model twice in the × direction and 4 times in the y direction. The dimensions of the new grid were thus 18 × 36 × 4. There were 8 injection wells and 8 production wells in the new grid.

The MULTIFLOOD simulator of Todd, Dietrich & Chase, Inc. was used to run the numerical model. The simulator is 3-dimensional, 3-phase, and compositional. It solves the system of partial differential equations by the finite difference technique and Newton-Rafson iteration. The system of linear equations is solved by Gaussian elimination with alternate diagonal ordering.

The scalar version of MULTIFLOOD was used in benchmarking. A ground rule was established that no changes were to be made to optimize the source code for each computer. However, the object code could be optimized by involving the appropriate compiler options or directives for vectorization on the CRAY and the CONVEX or for parallelization on the ALLIANT. On the TRACE, a fine tuning tool was used to assist the compiler in unrolling and in automatic inlining of the object code.

In evaluating the benchmark results, the simulator calculations are grouped into 4 categories. They are: physical properties evaluation, formation of finite difference coefficients, solution of linear equations, and miscellaneous calculations.
Application of Spatial Pedotransfer Functions to Understand Soil Modulation of Vegetation Response to Climate
Authors: Levi Matthew R. , Schaap Marcel G. , Rasmussen Craig
Published: September 2015

A fundamental knowledge gap in understanding land–atmosphere interactions is accurate, high‐resolution spatial representation of soil physical and hydraulic properties. We present a novel approach to predict hydraulic soil parameters by combining digital soil mapping techniques with pedotransfer functions (PTFs) and demonstrate that simple derived quantities are related to observed spatial patterns in ecosystem production during the North American Monsoon. Landsat reflectance and elevation data were used to predict physical soil properties at a 5‐m spatial resolution for a semiarid landscape of 6265 ha using regression kriging. Resulting soil property maps were applied to the Rosetta PTF to predict saturated hydraulic conductivity and water retention parameters from which approximate water residence times were derived. Estimated idealized residence time for water lost to the deeper vadose zone and evapotranspiration corresponded to vegetation response. Antecedent precipitation was more important for explaining the relationships between modeled soil properties and vegetation response than the amount of monsoon precipitation. Increased spring precipitation before the monsoon produced stronger negative correlations with hydraulic conductivity and stronger positive correlations with plant available water. Modeled water residence times explained the patterns of vegetation and landscape morphology validating our approach as a method of producing functional spatial PTFs. Linking digital soil mapping with Rosetta led to predictions of hydraulic soil properties that were more closely related to vegetation dynamics than the data available in the Soil Survey Geographic (SSURGO) soil database.
Electrical Conductivity Breakthrough Experiment and Immobile Water Estimation in Organic Substrates: Is R = 1 a Realistic Assumption?
Authors: Caron Jean , Létourneau Guillaume , Fortin Josée
Published: September 2015

Core Ideas

Breakthrough of NaCl in peat shows that R may differ from 1.

Immobile water in peat is difficult to estimate because of NaCl sorption.

Solute sorption in peat varies because of uncoiling of organic components.

Measuring electrical conductivity (EC) in outflow breakthrough curves (BTCs) is an approach commonly used to define transport parameters because it is rapid, inexpensive, and reliable. Earlier work has raised questions regarding the assumption that the retardation factor may be set at R = 1 when using EC as a tracer in organic soils. This study investigates the breakthrough of a NaCl tracer in a peat–sawdust mixture leached with distilled water. The results show that in such system, R may significantly differ from 1 because of sorption of Na+ and Cl− by peat with the R value estimated by batch experiments to reach 1.9 for Na+ and 1.5 for Cl−. The sorption properties may vary during solute transport because of uncoiling of humic and fulvic components with decreasing ionic strength of the solution.

Isolation and identification of a new set of microsatellite loci from Ucides cordatus genome
Authors: Araújo Erlane , Britto Fábio , Carvalho Adriana , Orasmo Gleice , Diniz Fábio
Published: September 2015

A new set of microsatellite loci (simple sequence repeats, SSRs) from the
overexploited mangrove crab Ucides cordatus is described in this study.
Microsatellite isolation used a highly simplified and inexpensive protocol
based on (i) multiple enzyme digestion/ligation; (ii) mixed biotin-labeled
probes and streptavidin-coated magnetic bead hybridization capture strategy,
and (iii) a double-repeat-enrichment procedure. A genomic library,
double-enriched for inserts containing tetranucleotide repeat motifs
[(GACA)6, (GATA)7, (GGAT)5 and (GTAT)5], was constructed to increase the
chance of recovering SSR-containing sequences within DNA fragments. Amplified
enriched DNA was cloned and transformed into competent E. coli. Then,
positive clones were identified by 'white/blue plaque selection?. One hundred
and five colonies were PCR-screened for sequencing, and 72 of these were
found to have unique SSR inserts. Microsatellite motifs contained more than
five repeats, and most loci were found to have perfect tandem repeats
(51.4%), of which 94.4% were dinucleotide and 5.5% trinucleotide. Only 20% of
all loci were compound and 28.6% were imperfect repeats containing di-, tri-
and/or tetranucleotides. The high frequency of perfect repeat motifs after
enrichment is additional evidence of the importance of adopting this
procedure for the isolation of SSR. The novel 34 SSRs described in this study
are expected to be highly polymorphic and, therefore, useful in
population/stocks discrimination of this valuable mangrove species throughout
its range, currently subjected to excessive fishing efforts.
Competitive Networks and School Leaders’ Perceptions
Authors: Jabbar Huriya
Published: September 2015

School choice policies are often based on the idea that competition will generate better outcomes for all students. Yet there is limited empirical research about how school leaders actually perceive competition and whom they view as rivals. Drawing on concepts from economic sociology, I study principals’ competitive networks and the sets of schools they view as rivals, and I use network and statistical analysis to explore factors that explain the existence of a competitive tie between two schools. Most school leaders perceived some competition, but the extent to which they competed with other schools varied significantly. Factors that predicted a competitive relationship between two schools included geography, student transfers, school performance, principal characteristics, and charter network.
Comparative study of functional outcome between plantar fascia stretching and achilles tendon stretching exercises in choronic plantar fasciitis
Authors: Shrestha S , Rai S , Limbu H , Bajracharya S
Published: September 2015

Background: Plantar fasciitis is a self limiting disease, with only 10% of patient developing chronic condition even after ten months. We hypothesized that patient with chronic plantar fasciitis who are treated with standard plantar fascia stretching program can have a better functional outcome than those treated with Achilles tendon-stretching exercise.Method: Forty patients who had chronic plantar fasciitis for duration of at least ten months were randomized into one of two groups. Group A received plantar stretching exercise and Group B had Achilles tendon stretching program. All patients completed the pain subscale of Foot Function Index and a subject relevant outcome survey that incorporated generic and condition-specific outcome measures related to pain, function and satisfaction with treatment outcome.Result: The pain subscale scores of the Foot Function Index showed significantly better results at eight weeks for the patients managed with plantar fascia stretching program respect to item 1 (worst pain; p = 0.004) and item 2 (first steps in the morning; p =0.001). Similarly at ten months follow up, pain subscale score comparison was statistically significant for item 1 (p = 0.018) and item 2 (p =0.003).Conclusions: A treatment method of non-weight-bearing stretching exercises specific to plantar fascia is superior to the conventional method of weight-bearing Achilles tendon-stretching exercises for treating patients with chronic plantar fasciitis.Nepal Journal of Medical Sciences Vol.3(2) 2014: 84-88
Body weight perception by college going adolescents of North Karnataka, India- A cross sectional study
Authors: Banjade B , Naik VA , Narasannavar AB
Published: September 2015

Background: Adolescence (10-19 year) is a period of transition from childhood to adulthood. The factor that determines how adolescents feel about themselves is ‘Body image’. The objective of study is to understand body weight perception of adolescents.Methods: This cross-sectional study was conducted in the two Pre- University colleges with a sample of 330 adolescents. Pre-designed and pre-tested questionnaire was used to elicit the required information.Results: 13 % of study participants underestimated their body weight and 11.2 % over estimated their body weight. 82.7% of study subjects perceived themselves as normal weight for their age and height, 7.6% perceived as underweight and 9.7% perceived as overweight/obese.Conclusion: Inappropriate perceptions about body weight leads to increase in the problems related to overweight/obesity. Lack of knowledge about and access to growth charts has probably made difficult for adolescents to evaluate their weight status objectively. So, college can play an effective role to help them to know actual body weightNepal Journal of Medical Sciences Vol.3(2) 2014: 106-109
Asphalt Concrete Field Compactibility Models Focusing on Aggregate Properties and Moisture
Authors: Cox Ben C. , Howard Isaac L. , Williams Kevin L. , Cooley L. Allen
Published: September 2015

Some aggregates used in asphalt production retain fine dust coatings after crushing and washing operations, and these coatings, especially when coupled with moisture, can be severe enough to cause asphalt mixture tender-zone characteristics. This paper's objective was to investigate asphalt mixture field compactibility by focusing on aggregate properties (e.g., moisture content and dust coating). In cooperation with the Mississippi Department of Transportation (DOT), 12 asphalt mixtures and 44 test locations were selected and studied. Considered for selection were mixtures with which the Mississippi DOT had experienced tenderness issues that were thought to be related to aggregate-adhered fines or aggregate moisture. Field compactibility was investigated with multiple regression procedures where air void (Va) level was the selected response variable. For each paving project, 31 material, production, and construction properties were collected for consideration within regression models. Through screening and processing procedures, the set of properties was refined to develop three regression models with R2 values ranging from .74 to .86. These models incorporated terms for fine aggregate angularity (FAA), surface area of coarse aggregate (SA8), cold-feed aggregate methylene blue value (MBVCF), cold-feed aggregate moisture (wCF), and other mixture properties (e.g., asphalt content and lift thickness). Key findings were the following: aggregate-adhered fines (ASTM D5711) and FAA had no effect on Va; increasing wCF slightly negatively affected Va; and increasing MBVCF positively affected Va. In general, aggregate property effects on Va were less meaningful than other properties included (e.g., lift thickness). Overall, regression models could be valuable to agencies and contractors for general guidance regarding factors affecting Va.
Quick Determination of Freeze–Thaw Durability of Concrete Aggregates Using the Indiana Department of Transportation Hydraulic Fracture Test Equipment
Authors: Desta Belayneh , Whiting Nancy , Olek Jan , Snyder Mark , Nantung Tommy
Published: September 2015

The freeze–thaw durability of carbonate aggregates can vary greatly, from durable to highly susceptible to freeze–thaw distress. Using nondurable aggregate in concrete pavement exposed to freeze–thaw cycles may lead to serious distress and greatly decrease the pavement's service life. The testing needed to identify freeze–thaw durable aggregates can take several months to complete. The main objective of this study was to develop a reliable, quick test method for determining the freeze–thaw resistance of carbonate aggregates quarried in Indiana by using the hydraulic fracture test (HFT) equipment. Aggregate samples collected from 18 quarried carbonate sources that represented a range of freeze–thaw performance were subjected to HFT with the modified Indiana Department of Transportation (Indiana DOT) HFT equipment. Aggregates from the same sources were also used to produce concrete beams that were subjected to the Indiana DOT-modified AASHTO T161-B freeze–thaw test. This test evaluated the dilation of beams exposed to freeze–thaw cycles. The experimental data were analyzed statistically, and a linear regression model was developed to predict the average percent dilation of freeze–thaw test beams using parameters obtained from HFT results. Comparing the predicted dilations to the measured dilations gave an adjusted R2 value of .85 and indicated that the model has a high degree of certainty. The modified Indiana DOT HFT equipment, refined test procedures, and data analysis developed during this study are recommended as screening tools for predicting AASHTO T161–ASTM C666 test results in 8 days. However, further testing is necessary to refine and validate the model before it is fully implemented as an accepted standard.
Delegated integrity check for hierarchical cloud data
Authors: Shen Shiuan-Tzuo , Tzeng Wen-Guey
Published: September 2015

Abstract

In cloud storage, a data owner can store his data in a cloud and authorize some users to access his data. Since the data are outsourced to the cloud, the authorized users should check the data to assure integrity. The data owner does not allow unauthorized users to check integrity of his data. There are many private and public integrity check schemes. Nevertheless, this paper concerns the verification key spread problem. Delegated integrity check deals with the verification key spread problem and provides effective management of verifiers. A data owner can delegate a verifier to check his data and revoke the right of the verifier later. The verifier cannot re-delegate his integrity check capability to someone else. Delegated integrity check guarantees that only the delegated verifier can check integrity of data.

This paper provides the model of delegated integrity check, an application scenario of personal health records, and two delegated integrity check schemes for hierarchical cloud data. The first scheme allows a verifier to check data possession of a storage server. The second scheme allows a verifier to check data retrievability from a storage server. The schemes achieve proof unforgeability, proof indistinguishability and delegation key unforgeability in the random oracle model.
CookiExt: Patching the browser against session hijacking attacks
Authors: Bugliesi Michele , Calzavara Stefano , Focardi Riccardo , Khan Wilayat
Published: September 2015

Abstract

Session cookies constitute one of the main attack targets against client authentication on the Web. To counter these attacks, modern web browsers implement native cookie protection mechanisms based on the HttpOnly and Secure flags. While there is a general understanding about the effectiveness of these defenses, no formal result has so far been proved about the security guarantees they convey. With the present paper we provide the first such result, by presenting a mechanized proof of noninterference assessing the robustness of the HttpOnly and Secure cookie flags against both web and network attackers with the ability to perform arbitrary XSS code injection. We then develop CookiExt , a browser extension that provides client-side protection against session hijacking, based on appropriate flagging of session cookies and automatic redirection over HTTPS for HTTP requests carrying these cookies. Our solution improves over existing client-side defenses by combining protection against both web and network attacks, while at the same time being designed so as to minimise its effects on the user’s browsing experience. Finally, we report on the experiments we carried out to practically evaluate the effectiveness of our approach.

All consecutive patients with severe sepsis were enrolled as study subjects.Results: A total of 228 patients were admitted in ICU and among them, 95 patients of severe sepsis were included . The mean age of the patients was 59.56 years & male to female ratio being 3:2. Ninety two (92% ) patients had any kind of comorbidity. Commonest comorbidity was diabetes mellitus (77%). Respiratory, renal dysfunction, and cardiovascular, were the most frequent organ dysfunctions (87% , 64%, 58%, respectively). In severesepsis patients single organ dysfunction was 30 %, double organ dysfunction was also 30% & triple organ dysfunction was 35% of patients. The most common primary source of infection were the respiratory system 70%, followed by urinary tract11% , intravascular catheter related infection 7% and abdomen 5%.Conclusion: Severe sepsis is a significant & common health problem in ICU Patients of Bangladesh. An understanding of the primary sources of severe sepsis is vital for treatment and these information will allow us to make preventive strategy for severe sepsis.Bangladesh Crit Care J September 2015; 3 (2): 45-48

Objective: To determine etiological pattern of patients presenting with upper gastrointestinal bleeding in a tertiary care hospital of Bangladesh.Methods: This study was a prospective observational study, carried out in the Department of Gastroenterology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from January 2013 to June 2013. Fifty adult patients presenting with haematemesis and/or melaena admitted into gastroenterology inpatient unit from outpatient department or patients referred from other inpatient units of Department of Medicine of BSMMU were included in the study. Endoscopic examination was performed within 24 to 48 hours of presentation. Lower GI endoscopy was done in selected cases.Results: The study patients were predominantly young or of early middle age with mean age being 34.45 ± 16.5 yrs. A male preponderance was observed with male to female ratio being 7.3:1 (44 male and 6 female). 62% of the patients presented with both haematemesis and melaena, 26% with melaena only and 12% with haematemesis alone. Endoscopy of upper gastrointestinal tract demonstrated duodenal ulcer to be predominant finding (50%), followed by gastro-esophageal erosions (20%), gastric ulcer (12%), esophageal varices (10%), gastric adenocarcinoma (4%) and stomal ulcer (4%).Conclusions: Endoscopy revealed that duodenal ulcer was the most common cause of upper gastrointestinal bleeding followed by oesophageal erosion, gastric ulcer, esophageal varices and stomal ulcer. Peptic ulcer disease still remains as the major cause of acute upper gastrointestinal haemorrhage, though cases of oesophageal erosion were also significant.Bangladesh Crit Care J September 2015; 3 (2): 60-62
Physical Rehabilitation in the ICU

Intensive care unit (ICU) based rehabilitation has become an important evidence-based component in the management of patients with critical illness. In addition to critical illness, prolonged bed rest and immobility may lead to severe physical deconditioning and loss of muscle mass and muscle weakness. Intensive care unit acquired weakness is associated with increased duration of mechanical ventilation and weaning, longer ICU and hospital stay, and increased mortality. These physical impairments may last for years after ICU discharge. Early Physical Medicine and Rehabilitation (PM&R) interventions in the ICU may attenuate or prevent the weakness and physical impairments occurring during critical illness. This article reviews the effects of prolong bed rest and inactivity, early PM&R interventions, their safety, feasibility, benefits and future directions for early PM&R in the ICU.Bangladesh Crit Care J September 2015; 3 (2): 63-66

Published: September 2015

Meliodosis, caused by the gram negative saprophyte Burkholderia pseudomallei, is very difficult to diagnose clinically because of varied presentations and lack of awareness. It causes various clinical manifestations like pneumonia, septicaemia, septic shock, septic arthritis, abscesses in different organs etc. The organism can be difficult to identify in laboratories with little experience of B pseudomallei. For effective and timely initiated treatment, clinicians and microbiologists should communicate with each other. Here we report a case of a middle aged diabetic lady who presented with septic arthritis. Burkholderia pseudomallei was isolated from blood and synovial fluid cultures. The unfortunate woman succumbed to death from septic shock before diagnosis.Bangladesh Crit Care J September 2015; 3 (2): 74-76

From Altered States to Altered Titles: A Close Analysis of the Title Sequence to Ken Russell's Altered States (1981)
Authors: Post Jack
Published: September 2015

Although most title sequences of Ken Russell's films consist of superimpositions of a static text on film images, the elaborate title sequence to Altered States (1981) was specially designed by Richard Greenberg, who had already acquired a reputation for his innovative typography thanks to his work on Superman (1978) and Alien (1979). Greenberg continued these typographic experiments in Altered States. Although both the film and its title sequence were not personal projects for Russell, a close analysis of the title sequence reveals that it functions as a small narrative unit in its own right, facilitating the transition of the spectator from the outside world of the cinema to the inside world of filmic fiction and functioning as a prospective mise-en-abyme and matrix of all the subsequent narrative representations and sequences of the film to come. By focusing on this aspect of the film, the article indicates how the title sequence to Altered States is tightly interwoven with the aesthetic and thematic structure of the film, even though Russell himself may have had less control over its design than other parts of the film.

Sports and energy (S/E) drinks are commonly used by high school (HS) athletes, yet little is known about this population’s consumption patterns or the drinks’ side-effects. The objectives of this pilot study were to survey HS athletes about their use of S/E drinks and assess potential side-effects. One hundred American HS athletes (72 were female; 27 were male; one did not identify gender) were part of a cross-sectional internet-based survey. The mean age of the athletes was 16.0 ± 1.1 years. The athletes self-reported S/E consumption patterns, motivations for consumption, and drink side-effects. Nearly two-thirds (59.5%) of athletes surveyed were at least occasional users of sports drinks, and more than one-third (37.3%) were at least occasional users of energy drinks. Of the athletes who had ever drunk an S/E drink, 49.5% drank their first sport drink at ≤ 8 years and 41.3% consumed their first energy drink ≤ 11–12 years of age. The most common motivation for consumption of sports drinks was to rehydrate (84.1%) and of energy drinks was to gain energy (61.8%). Side effects of S/E drinks were frequently reported; 25.3% of energy drink users reporting being nervous/jittery after consumption. Thus HS athletes should be cautioned about consumption of S/E drinks until more is understood about their short- and long-term side-effects.

Published: September 2015

This paper proposes a hybrid algorithm to solve the optimal energy dispatch of an ice storage air-conditioning system. Based on a real air-conditioning system, the data, including the return temperature of chilled water, the supply temperature of chilled water, the return temperature of ice storage water, and the supply temperature of ice storage water, are measured. The least-squares regression (LSR) is used to obtain the input-output (I/O) curve for the cooling load and power consumption of chillers and ice storage tank. The objective is to minimize overall cost in a daily schedule while satisfying all constraints, including cooling loading under the time-of-use (TOU) rate. Based on the Radial Basis Function Network (RBFN) and Ant Colony Optimization, an Ant-Based Radial Basis Function Network (ARBFN) is constructed in the searching process. Simulation results indicate that reasonable solutions provide a practical and flexible framework allowing the economic dispatch of ice storage air-conditioning systems, and offering greater energy efficiency in dispatching chillers.
