Syncretic Arenas: Essays on Postcolonial African Drama and Theatre for Esiaba Irobi (2015)

Syncretic Arenas: Essays on Postcolonial African Drama and Theatre for Esiaba Irobi, ed. by Isidore Diala (Rodopi, 2014)Syncretic Arenas is one of the few Festschriften combining the structure of the liber amicorum with a substantial take on a specific area of investigation. It is a compelling anthology honor of the Nigerian-born playwright, poet and scholar Esiaba Irobi (1960-2010) and, at the same time, it actively contributes to the ongoing researches on postcolonial African drama as a transnational and transcultural phenomenon. Irobi's work, fact, provides an interesting case study for those who advocate the necessity of a 'transcultural turn' literary and cultural studies. As aptly reminded by the editor Isidore Diala the introduction to the volume, Irobi 'liked to describe himself as a Biafran who led all his life in exile Nigeria, the UK and the USA' (xix), but he also managed to transform this multiple exclusion into a multifaceted creative production. Differently from his renowned predecessors Soyinka and Pepper Clark, however, Irobi has been quite neglected the field of Postcolonial Studies until the publication of this volume, which also stands as a major contribution on the author.The first section of the book is entirely devoted to Esiaba Irobi, whose memory is celebrated different ways, ranging from individual memories to a series of poems dedicated to him by fellow writers such as Biodun Jeyifo, Benedictus Nwachukwu, Obiwu and Olu Oguibe. Nwachukwu's Half a Century Death, particular, manages to effectively convey the core of Irobi's life and works, as it might be appreciated these two stanzas:Your performance strategy thrilled thosein the house of words who profess truth;the Soyinkan model, the Shakesperean compass.Cultural appropriation to the core. Half a century plague.Creative, one, like pollination, east and west.You presented us with wordsof gold, frankincense and myrrhmoments later you departed from the forest of words. (54)Cultural appropriation and cross-pollination are, indeed, fundamental elements of Irobi's creative process, as he took advantage both of his 'holistic education' (104) - which he recalls his long interview with Leon Osu (103-132) - and the propensity to cultural syncretism of his most renowned predecessors, Wole Soyinka and John Pepper Clark, and his fellow writer Chimamanda Ngozi Adichie, whom Irobi repeatedly praises within the same interview.Regarding Soyinka, particular, the whole book follows the path opened by Isidore Diala's previous works on Irobi's drama, underlining, thus, the latter's tight relationship with Soyinka's oeuvre. On the one hand, fact, Irobi's play quoted by Nwachukwu, Gold, Frankincense and Myrrh (1989), seems to be 'a parody of the many conferences of the 1960s and 1970s which African writers and scholars attempted to identify and define the prime virtues of neo-African literature' (70), including Soyinka the list. …
Photoelectrochemical Tandem Cells for Solar Water Splitting (2013)

In order to be economically competitive with simple "brute force" (i.e., PV + electrolyzer) strategies or the production of promising solar fuels, like H-2, from fossil fuels, a practical photoelectrochemical device must optimize cost, longevity, and performance. A promising approach that meets these requirements is the combination of stable and inexpensive oxide semiconductor electrodes in a tandem photoelectrochemical device. In this article, we give an overview of the field including an examination of the potential solar-to-fuel conversion efficiency expected in a device with realistic losses. We next discuss recent advances with increasing the performance of promising semiconductor electrode materials and highlight how these advances have led to state-of-the-art solar-to-chemical efficiencies in the 2-3% range in real devices. Challenges for further optimization are further outlined.
Optimization of RAPD for fingerprinting <b> <i>Salmonella</i> </b> (1997)

Random amplification of polymorphic DNA (RAPD) is proving to be a useful technique in studying the epidemiology of micro-organisms. The technique can be troublesome and time consuming to establish due to the essentially empirical approach to optimization. By standardization of certain parameters and use of a commercially available PCR buffer optimization kit, a particularly promising primer was identified and RAPD conditions for a highly discriminatory and reproducible characterization of Salmonella isolates was achieved. In addition, a technique to obtain reproducible RAPD fingerprints of Salmonella isolates without the need to purify genomic DNA is described.
Influence of atmospheric stability on wind turbine loads (2012)

ABSTRACT Simulations of wind turbine loads for the NREL 5 MW reference wind turbine under diabatic conditions are performed. The diabatic conditions are incorporated in the input wind field in the form of wind profile and turbulence. The simulations are carried out for mean wind speeds between 3 and 16 m s − 1 at the turbine hub height. The loads are quantified as the cumulative sum of the damage equivalent load for different wind speeds that are weighted according to the wind speed and stability distribution. Four sites with a different wind speed and stability distribution are used for comparison. The turbulence and wind profile from only one site is used in the load calculations, which are then weighted according to wind speed and stability distributions at different sites. It is observed that atmospheric stability influences the tower and rotor loads. The difference in the calculated tower loads using diabatic wind conditions and those obtained assuming neutral conditions only is up to 17%, whereas the difference for the rotor loads is up to 13%. The blade loads are hardly influenced by atmospheric stability, where the difference between the calculated loads using diabatic and neutral input wind conditions is up to 3% only. The wind profiles and turbulence under diabatic conditions have contrasting influences on the loads; for example, under stable conditions, loads induced by the wind profile are larger because of increased wind shear, whereas those induced by turbulence are lower because of less turbulent energy. The tower base loads are mainly influenced by diabatic turbulence, whereas the rotor loads are influenced by diabatic wind profiles. The blade loads are influenced by both, diabatic wind profile and turbulence, that leads to nullifying the contrasting influences on the loads. The importance of using a detailed boundary‐layer wind profile model is also demonstrated. The difference in the calculated blade and rotor loads is up to 6% and 8%, respectively, when only the surface‐layer wind profile model is used in comparison with those obtained using a boundary‐layer wind profile model. Finally, a comparison of the calculated loads obtained using site‐specific and International Electrotechnical Commission (IEC) wind conditions is carried out. It is observed that the IEC loads are up to 96% larger than those obtained using site‐specific wind conditions.Copyright © 2012 John Wiley & Sons, Ltd.
Two-point Euclidean shortest path queries in the plane (1999)

We consider the two-point query version of the fundamental geometric shortest path problem: Given a set h of polygonal obstacles iu the plane, having a total of n vertices, build a data structure such that for any two query points s and t we can efficiently determine the length, d(s,t), of an Euclidean shortest obstacle-avoiding path, *(s,t), from s to t. Additionally, our data structure should allow one to report the path x(s, t), in time proportional to its (combinatorial) size. We present various methods for solving this two-point query problem, including algorithms with o(n), O(log n+h), 0( h log n), O(log’ n) or optimal O(log n) query times, using polynomial-space data structures, with various tradeoffs between space and query time. While severa results have been known for approtimate twepoint Euclidean shortest path queries, it has been a well-publicized open problem to obtain sublinear query time for the exact version of the problem. Our methods also yield data structures for twc+point shortest path queries on nonconvex polyhedral
Adjunctive Chemotherapy of Infection-Induced Staghorn Calculi (1979)

Bacteria induce urinary crystallization of struvite and carbonate-apatite as a by-product of ureolysis by urease. Eradication of infection and/or inhibition of urease with acetohydroxamic acid for 5 to 30 months retarded stone growth and brought about partial or comple dissolution of stones in 9 patients. Long-term chemotherapy with antimicrobial agents that achieve steril urine or acetohydroxamic acid in those patients with recalcitrant infection lessens the risk of recurrent calculogenesis.
Valuing the Reload Features of Executive Stock Options (1999)

For options with a reload feature, the holder is automatically entitled to new options when the initial option is exercised. Under Statement of Financial Accounting Standards No. 123, the grant date value of executive stock options excludes the value of a reload feature because the Financial Accounting Standards Board believes it is not feasible to value a reload feature at the grant date. We show how the Binomial Option Pricing Model can be used to value options and the reload feature at the grant date. Ignoring the reload can substantially understate the value of the option. Accordingly, the Financial Accounting Standards Board may wish to reconsider the accounting for reload features.
Photosynthesis and nutrient‐use efficiency of barley in response to low arbuscular mycorrhizal colonization and addition of phosphorus (1996)

The effects of arbuscular mycorrhizal infection by Glomus mosseae (Nicol. & Gerd.) Gerd. & Trappe on growth and photosynthesis of barley (Hordeum vulgare L. cv. Manitou) were investigated in sand culture at five levels of calcium phosphate (50, 100, 200, 400 and 800 mg P kg(-1) ). Mycorrhizal infection was low and varied with P supply, declining from 3.3% at 50 mg P kg(-1) to 1.5% at the highest P concentration. In general, there were small differences in biomass between mycorrhizal (+AM) and non-mycorrhizal (-AM) barley but a significant reduction in dry mass of senesced leaves occurred in the +AM plants. Leaf P concentrations increased with P application, but did not differ between + AM and -AM plants. Although there were no differences in dry mass between + AM and -AM plants at 50 mg P kg(-1) , it was at this lowest P supply that +AM plants had higher rates of photosynthesis and greater P-use and N-use efficiencies. The mycorrhizal enhancement of maximum photosynthetic rate at the lowest P level was associated with a higher stomatal conductance, but was not related to increased leaf P or to changes in photon yield or the ratio of variable (FV) to maximum (FM) chlorophyll fluorescence.
A memory architecture using linear and nonlinear feedback shift registers for data security (2015)

In this paper, memory architecture for ensuring data security is proposed. A Graphical User Interface (GUI) is assumed in the work to enter user ID and password for each user authentication. Valid user will be given access to the corresponding data whereas invalid user will be given access but will receive garbage data to prevent multiple trails to break in. The architecture using Galois type Linear Feedback Shift Registers (LFSRs) as well as Nonlinear Feedback Shift Registers (NLFSRs) is implemented and verified for the functionality. The power consumption is estimated using 180nm Cadence RTL Compiler and the level of data security using the National Institute of Standards and Technology (NIST) test suite for random numbers and compared the results achieved through the two implementations. The power consumption is 2.291 mW for NLFSR type of implementation and is less than that of the LFSR type of implementation by 23.9%. It is observed that NLFSR type of implementation passes the four NIST tests and whereas the LFSR type of implementation fails in two out of the four NIST tests.
Injuries in women’s professional soccer (2005)

We conclude that the injury incidence in the WUSA is lower than the 6.2 injuries per 1000 player hours found in the corresponding male professional league (Major League Soccer); however, knee injuries predominate even in these elite female athletes.
Treatment of Osteochondral Lesions of the Talus With Autologous Chondrocyte Implantation (2004)

Osteochondral lesions of the talus are a known cause of chronic ankle pain. Cartilage lacks an intrinsic healing mechanism; therefore, patients with this pathology often present to surgery. Multiple treatment methods have been advocated, including debridement, drilling, microfracture, osteochondral allografts/autografts, and autologous chondrocyte implantation. Autologous chondrocyte implantation is a technique that has been applied in the treatment of knee articular defects. We have used this technique to treat osteochondral lesions of the talus that have failed previous surgical treatment or have a large subchondral bone deficit.
Energy-efficient FPGA Implementation of the k-Nearest Neighbors Algorithm Using OpenCL (2016)

SoCs are getting increasingly heterogeneous with a combination of multi-core architectures and hardware accelerators to speed up the execution of computeintensive tasks at considerably lower power consumption. Modern FPGAs, due to their reasonable execution speed and comparatively lower power consumption, are strong competitors to the traditional GPU based accelerators. High-level Synthesis (HLS) simplifies FPGA programming by allowing designers to program FPGAs in several high-level languages e.g. C/C++, OpenCL and SystemC.
Breathalysers : no hot air : behaviour (2011)

One breathalyser test is much like another. Or is it? Breathalysers are technically designed instruments with a long - and sometimes amusing - tradition.
Vascular Tissue Engineering and Vascularized 3D Tissue Regeneration (2007)

Vascularized tissue regeneration has a great deal of potential in clinical medicine. Appropriate 3D tissue regeneration that yields tissue with the desired function and shape requires both growth signals and vascularization. In this paper, we discuss vascularized tissue regeneration using various vessel systems: artificial vessel, autologous vascular graft, autologous vascular bundle transfer and tissue engineered vessel. Vascularized 3D tissue regeneration will require a great deal of additional research before it can be applied to clinical situations. Several promising studies of vascularized tissue regeneration have been reported. However, additional studies into the maturation of neovascularization, the development of effective biomaterial, and the possibility of using stem cells will be needed before these techniques can be used in the clinical situation.
Right Family Relationships (1925)

Right family relationships are identical with happy family relationships. This thought, a magic wand, lightens all of our candles but one-the strange little blue one- and in their soft but intense light the treasures of our home will shine, will send out new streams of light. For our home is the focus into which we gather faithfully the best that is in our time and from which we send out more powerful rays, intensified by the best of the members of the family, to illuminate the world and to show the roads to progress.
Chronic telogen effluvium or early androgenetic alopecia? (2004)

A 16‐year‐old girl presented with a 12‐month history of generalized hair shedding from the scalp. The onset of shedding coincided with the development of Hashimoto's thyroiditis and iron deficiency. At the time of initial presentation, the Hashimoto's thyroiditis had been treated with Neo‐Mercazole and she was euthyroid. Her iron stores were low, with a ferritin level of 13 µg/L. As she was vegetarian, oral iron replacement therapy was commenced without further investigation. On follow‐up 6 months later, her iron stores were normal (ferritin, 36 µg/L), but the hair shedding had continued. On examination, there was a positive hair pull test from both the vertex of the scalp and the occipital scalp. There was mild bitemporal recession, but no widening of the central part, and she appeared to have a full, thick head of hair ( Fig. 1 ). Additional investigations at that time revealed normal thyroid function and negative antinuclear antibody (ANA) and syphilis serology. She was on no medication other than Neo‐Mercazole. Serum testosterone, dihydroepiandosterone sulphate (DHEAS) and sex hormone binding globulin (SHBG) were normal. Two 4‐mm punch biopsies were taken from the vertex of the scalp; one was sectioned horizontally and the other vertically. The vertical section was unremarkable. On the horizontal section, there were 32 hair follicles in total, 30 of which were terminal hairs and two of which were vellus hairs. One hair was in telogen. The ratio of terminal to vellus hairs was 15 : 1. Initial presentation image A diagnosis of chronic telogen effluvium was made. The condition was explained to the patient and she was reassured that chronic telogen effluvium is not a progressive condition and does not lead to baldness. No treatment was recommended. At follow‐up 12 months later, the hair loss had obviously progressed and the patient was assessed as having Ludwig Stage 1 androgenetic alopecia with widening of the central part ( Fig. 2 ). Repeat blood tests showed normal iron studies, thyroid function, and hormone parameters. Three 4‐mm punch biopsies were taken from the vertex of the scalp and all were sectioned horizontally. The terminal to vellus hair ratios were 1 : 1, 2.6 : 1, and 1.9 : 1. A diagnosis of androgenetic alopecia was made and she was commenced on oral spironolactone, 200 mg/day.

Embedded Databases for Embedded Real-Time Systems: A Component-Based Approach1 (2002)

Effects of two "enhanced" treatments (drying and composting mesophilic anaerobically digested (MAD) biosolid) on nutrient leaching were investigated. Repacked sandy or sandy loam textured soil cores amended with fresh, dried and composted MAD biosolid (250 kg N ha(-1)), were investigated under steady-state hydrological conditions. Two 24 h, 4.5 mm h(-1) rainfall events, with a 14-day interval, were simulated using water-tracers. Losses of nitrate from the sandy loam soil during rainfall event 1 (43.9-68.0 mg kg(-1)) were significantly greater (P < or = 0.05) than during event 2 (6.4-11.9 mg kg(-1)). Phosphate losses were significantly greater (P < or = 0.05) during event 2 (up to 0.30 mg kg(-1)) compared to the first (< 0.05 mg kg(-1)). The sand soil showed similar effects. Losses of nitrate-N (percentage of total N applied) from the sand soil were small (around 0.06% for fresh/dried and 0.63% for composted MAD biosolids). Losses of nitrate-N from the sandy loam soil were greater; 4% for fresh and dried and 3% for composted MAD biosolids. This research showed that drying MAD biosolid had little impact on nitrate and phosphate losses from soil compared to fresh MAD biosolid. The effect of composting MAD biosolid on nutrient losses was more variable.
A transcriptional corepressor of Stat1 with an essential LXXLL signature motif (2001)

Interferon (IFN) treatment induces tyrosine phosphorylation and nuclear translocation of Stat1 (signal transducer and activator of transcription) to activate or repress transcription. We report here that a member of the protein inhibitor of activated STAT family, PIASy, is a transcriptional corepressor of Stat1. IFN treatment triggers the in vivo interaction of Stat1 with PIASy, which represses Stat1-mediated gene activation without blocking the DNA binding activity of Stat1. An LXXLL coregulator signature motif located near the NH(2) terminus of PIASy, although not involved in the PIASy-Stat1 interaction, is required for the transrepression activity of PIASy. Our studies identify PIASy as a transcriptional corepressor of Stat1 and suggest that different PIAS proteins may repress STAT-mediated gene activation through distinct mechanisms.
Polymers in Controlled Release Technology (1976)

Controlled release technology emerged actively from the 1960's with promises to solve a diversity of problems that have in common the application of some active agent to a system with the objective of accomplishing a specific purpose while avoiding certain other possible responses this agent might cause. A number of techniques for effecting controlled release have been identified and analyzed, and most of these have been considered for or embodied in commercial devices or formulations which already are or soon will be on the market. Most of these concepts have been described in the literature (patents, journals, books, etc.) The proceedings of previous symposia (1-3) and recent reviews (4-16) provide a rapid way to learn the present state of the art of this technology. One of the common features of many of these techniques or formulations is the judicious selection of a polymeric material to act as a rate controlling
Directional Cell Discovery in Millimeter Wave Cellular Networks (2015)

The acute disparity between increasing bandwidth demand and available spectrum has brought millimeter wave (mmWave) bands to the forefront of candidate solutions for the next-generation cellular networks. Highly directional transmissions are essential for cellular communication in these frequencies to compensate for higher isotropic path loss. This reliance on directional beamforming, however, complicates initial cell search since mobiles and base stations must jointly search over a potentially large angular directional space to locate a suitable path to initiate communication. To address this problem, this paper proposes a directional cell discovery procedure where base stations periodically transmit synchronization signals, potentially in time-varying random directions, to scan the angular space. Detectors for these signals are derived based on a Generalized Likelihood Ratio Test (GLRT) under various signal and receiver assumptions. The detectors are then simulated under realistic design parameters and channels based on actual experimental measurements at 28 GHz in New York City. The study reveals two key findings: 1) digital beamforming can significantly outperform analog beamforming even when digital beamforming uses very low quantization to compensate for the additional power requirements and 2) omnidirectional transmissions of the synchronization signals from the base station generally outperform random directional scanning.
