Food Production and Water Conservation in a Recirculating Aquaponic System in Saudi Arabia at Different Ratios of Fish Feed to Plants (2008)

Abstract An indoor aquaponic system (i.e., the integration of fish culture with hydroponic plant production in a recirculating setup) was operated for maximizing water reuse and year‐round intensive food production (Nile tilapia, Oreochromis niloticus , and leaf lettuce) at different fish feed to plants ratios. The system consisted of a fish culture component, solid removal component, and hydroponic component comprising six long channels with floating styrofoam rafts for holding plants. Fish culture effluents flowed by gravity from the fish culture component to the solid removal component and then to the hydroponic component. Effluents were collected in a sump from which a 1‐horsepower in‐line pump recirculated the water back to the fish culture tanks at a rate of about 250 L/min. The hydroponic component performed as biofilter and effectively managed the water quality. Fish production was staggered to harvest one of the four fish tanks at regular intervals when fish attained a minimum weight of 250 g. Out of the total eight harvests in 13 mo, net fish production per harvest averaged 33.5 kg/m 3 of water with an overall water consumption of 320 L/kg of fish produced along with the production of leaf lettuce at 42 heads/m 2 of hydroponic surface area. Only 1.4% of the total system water was added daily to compensate the evaporation and transpiration losses. A ratio of 56 g fish feed/m 2 of hydroponic surface effectively controlled nutrient buildup in the effluents. However, plant density could be decreased from 42 to 25–30 plants/m 2 to produce a better quality lettuce.
<title>Fabrication of microlens arrays by reactive ion milling</title> (1996)

Fabrication of refractive microlens arrays on several infrared (IR) transmissive materials was studied. The fabrication process consists of forming photoresist microlenses by thermal reflow of photoresist islands, and transferring this pattern into the IR substrate by ion milling. Microlens arrays having a wide range of F-numbers (F/0.3 - F/12) and sizes were fabricated using a modified ion milling process, where background oxygen and ion energy were used to control the photoresist and substrate erosion rates, respectively. This approach enabled a large range of milling selectivity (e.g. 0.6 - 12 for CdTe) and hence accurate control of lens sag heights. This is important since photoresist microlenses can be successfully fabricated only within a limited range of F-numbers. The etch selectivity also enabled fabrication of nonspherical shapes, starting from spherical photoresist preforms, by judicious control of sputter selectivity during the milling process. Microlens arrays were fabricated in several IR materials, including CdTe, ZnS, Ge, Si, GaAs, InP, GaP and Al<SUB>2</SUB>O<SUB>3</SUB>. Among these materials GaP and ZnS are also attractive visible and near IR wavelength microlens materials, where their high refractive index results in much lower sag heights than quartz lenses of comparable F-number.
Cooperation and Cognitive Radio (2007)

Cooperation is increasingly regarded as a key technology for tackling the challenges of a practical implementation of cognitive radio. In this paper, we first give a brief overview of the envisioned applications of cooperative technology to cognitive radio, distinguishing among cooperative sensing for detection of the primary activity, cooperative transmission between secondary nodes and cooperative transmission of primary traffic by secondary users (cognitive relaying). Then, we focus on the latter scenario and investigate a simple wireless network, where one secondary transmitter has the option to relay traffic of the primary. Assuming that the primary is oblivious to the presence of the secondary (thus excluding the possibility of spectrum leasing), the secondary transmitter optimizes transmission/ relaying parameters towards the goal of maximizing the rate towards the secondary receiver. Numerical results are provided in order to discuss the advantage and limits of cognitive relaying.

Efficient soliton compression by fast adiabatic amplification (1996)

It is shown that a properly tailored, rapidly increasing gain along the distance of propagation in a monomode fiber can provide fast but still adiabatic soliton amplification and therefore high-quality one-soliton compression for fiber lengths even shorter than the characteristic dispersive length. With the variational approach an explicit expression is given for the required variation of the inhomogeneous gain, and its validity is demonstrated by comparison with direct numerical simulations that include the calculation of the pure soliton component. It is also shown by analytical and numerical perturbation analysis that the compression scheme is stable with respect to small deviations from the ideal soliton form and gain variation. Finally, it is demonstrated that efficient soliton compression can also be obtained by cascading of instantaneous optical amplifiers in an intermediate fiber with higher dispersion, where nonlinear mode conversion preserves the soliton character of the amplified pulse. The practical implementation of these compressor schemes is discussed.
The Manufacturing Equipment Support Model Based on the Manufacturing Equipment Role (2013)

This work aims to investigate the manufacturing equipment support model for the purpose of improving the efficiency and quality of manufacturing. First,the concept of manufacturing capacity is defined,and the relationship between practical and expected manufacturing capacity is described. Then the concept of role is introduced and the manufacturing equipment role is defined in detail. Based on the analysis of manufacturing capacity and manufacturing equipment role,the three-stage manufacturing equipment support model is proposed. With this model,the manufacturing task can be decomposed into several manufacturing equipment roles,and the expended manufacturing capacity involved in the manufacturing equipment role can be matched with the practical manufacturing capacity of the enterprise. The measures are discussed depending on different matching degrees.
Aquatic Resources Management of the Colorado River Ecosystem (1983)

The Colorado River system has often been referred to as "the most regulated river system in the world." The Colorado River Basin serves millions of people through agricultural, energy, municipal and industrial uses, fish and wildlife activities, and recreation. The symposium was conceived and organized to allow researchers, private industry, consultants, water users, regulatory agencies, and concerned citizens the opportunity to express needs, desires, and concerns about the vast resources of the Colorado River. We found that there were a diverse number of problems confronting the individuals who are involved in the management of this important ecosystem. A variety of broad topics have been presented which include: water policy and major diversions; energy impacts; oil shale development--resources and impacts; Lake Mead and the other major reservoirs in the system; the ecology and management of the watershed and the riparian habitat in the system; fisheries; salinity problems; sedimentation; eutrophication; flow depletion; and water augmentation. This timely symposium brought together many individuals, representing a variety of disciplines, to discuss and transfer information appropriate to the needs of the Colorado River Basin. The results of this symposium, which have been compiled herein, are an attempt to examine current and projected effects of water and land management within the Colorado River Basin and to provide a basis for determining what can be done to better manage the resources within the total context of activities affecting the Colorado River Ecosystem.
A re-determination of the equal-loudness relations for pure tones (1956)

The paper describes a new determination of the equal-loudness relations for pure tones in free-field conditions which has been carried out at the National Physical Laboratory as a result of requests from organizations interested in various aspects of the acoustics of hearing. The equal-loudness contours are of considerable importance in this field, being fundamental to a proper understanding of aural judgments of the loudness of sounds of all kinds. They are also concerned in numerous practical applications in the study of noise.
An investigation of microbial contamination in the home (1982)

An investigation of the bacterial flora in over 200 homes is reported. The occurrence of potential pathogens and the levels of contamination at individual sites, particularly in the kitchen, toilet and bathroom is described and the implications for hygiene practices in the home discussed.
Down-regulation of the transcription factor snail in the placentas of patients with preeclampsia and in a rat model of preeclampsia (2012)

We demonstrated that human preeclampsia and the salt-induced rat model of preeclampsia are associated with the reduced levels of Snail protein in placenta. Down-regulation of the transcription factor Snail in placental progenitor cell lineages, either by intrinsic defects and/or by extrinsic and maternal factors, may affect normal placenta development and function and thus contribute to the pathology of preeclampsia.
The UCSC Kestrel Application-Unspecific Processor (2006)

The UCSC Kestrel parallel processor is part of an evolution from application-specific to specialized to application-unspecific processing. Kestrel combines an ALU, multiplier, and local memory, with systolic shared registers for seamless merging of communication and computation, and an innovative condition stack for rapid conditionals. The result has been a readily programmable and efficient co-processor for many applications. Experience with Kestrel indicates that programmable systolic processing, and its natural combination with the single instruction-multiple data (SIMD) parallel architecture, will be an effective design choice for years to come
Porting existing cache-oblivious linear algebra HPC modules to larrabee architecture (2010)

Cache-obliviousness represents an important but relatively new concept for cache optimization. As cache-oblivious algorithms perform well on architectures with arbitrary cache configurations, the programming effort required for porting and optimizing for future architectures can be significantly reduced. In [8] and [9], fast parallel cache-oblivious linear algebra modules have been presented. The underlying matrix storing schemes are based on space filling curves. For matrix multiplication, all cache misses can be avoided, whereas for the LU decomposition algorithm the number of cache misses is minimized. It has been shown that the resulting codes work very well on several kinds of systems ranging from laptops to supercomputers.
Inecalcitol, an analog of 1α,25(OH)<sub>2</sub>D<sub>3</sub>, induces growth arrest of androgen‐dependent prostate cancer cells (2011)

19-nor-14-epi-23-yne-1,25(OH)(2) D(3) (inecalcitol) is a unique vitamin D(3) analog. We evaluated the activity of inecalcitol in a human prostate cancer model system. The analog was 11-fold more potent than 1,25(OH)(2) D(3) in causing 50% clonal growth inhibition of androgen-sensitive human prostate cancer LNCaP cells. Inecalcitol, more than 1,25(OH)(2) D(3) , reduced in a dose-dependent manner the expression levels of the transcription factor ETS variant 1 and the serine/threonine protein kinase Pim-1, both of which are upregulated in prostate cancer. Remarkably, dose challenge experiments revealed that inecalcitol maximal tolerated dose (MTD) by intraperitoneal (i.p.) administration was 30 μg/mouse (1,300 μg/kg) three times per week, while we previously found that the MTD of 1,25(OH)(2) D(3) is 0.0625 μg/mouse; therefore, inecalcitol is 480 times less hypercalcemic than 1,25(OH)(2) D(3) . Pharmacokinetic studies showed that plasma half-life of inecalcitol were 18.3 min in mice. A xenograft model of LNCaP cells was developed in immunodeficient mice treated with inecalcitol. The tumors of the diluent-treated control mice increased in size but those in the inecalcitol treatment group did not grow. Our data suggest that inecalcitol inhibits androgen-responsive prostate cancer growth in vivo and should be examined either alone or with other chemotherapy in clinical trials in individuals with rising serum prostate-specific antigen after receiving either surgery or irradiation therapy with curative intent.
Empiric Use of Trimethoprim‐Sulfamethoxazole (TMP‐SMX) in the Treatment of Women with Uncomplicated Urinary Tract Infections, in a Geographical Area with a High Prevalence of TMP‐SMX–Resistant Uropathogens (2002)

This study evaluated whether trimethoprim-sulfamethoxazole (TMP-SMX) is effective for treatment of uncomplicated urinary tract infections (UTIs) due to TMP-SMX-resistant (TMP-SMX-R) pathogens. Healthy nonpregnant premenopausal women with symptomatic lower UTI were assessed for the presence of pyuria and bacteriuria; if either was present, a urine sample was cultured and TMP-SMX was prescribed. Clinical and microbiologic cure was assessed at days 5-9 and 28-42 after cessation of therapy. For 71%, of patients, cultures grew TMP-SMX-susceptible (TMP-SMX-S) microorganisms, and for 29%, cultures grew TMP-SMX-R organisms. Escherichia coli remained the predominant bacteria in both groups of cultures. At visit 2, microbiological cure had been achieved in 86% of the patients in the TMP-SMX-S group and 42% of those in the TMP-SMX-R group. Similar differences were found at visit 3 by clinical evaluation. Treatment with TMP-SMX of uncomplicated UTI caused by TMP-SMX-R microorganisms results in microbiologic and clinical failure. In high-resistance areas, TMP-SMX should not be the empiric drug of choice for uncomplicated UTI.
Collisions for Hash Functions MD4, MD5, HAVAL-128 and RIPEMD (2004)

MD5 is the hash function designed by Ron Rivest [9] as a strengthened version of MD4[8]. In 1993 Bert den Boer and Antoon Bosselaers [1] found pseudo-collision for MD5 which is made of the same message with two different sets of initial value. H. Dobbertin[3] found another kind of collision which consists of two different 512-bit messages with a chosen initial value I
5‐3: OLED Display Device Mounted with a Novel External Compensating Circuit (2018)

A prototype of an external compensating circuit including an integrator is fabricated for an organic light‐emitting diode display. This integrator includes an amplifier with two differential pairs to improve the accuracy of measuring current for external compensation for variations in transistor characteristics.
Murine CD4 T Cells Produce a New Form of TGF-β as Measured by a Newly Developed TGF-β Bioassay (2011)

A newly developed 293T-caga-Luc-CD32-CD86 reporter cell bioassay demonstrated that murine CD4 T cells produce an unconventional form of TGF-β which can induce TGF-β signaling. This new form of TGF-β contains LAP as a component. Our finding of a new form of T cell-produced TGF-β and the newly developed TGF-β bioassay system will provide a new avenue to investigate T cell function of the immune system.
Computer applications in the electrical utility industry (2002)

Recently, a line has emerged: on one side computer applications working productively for electric utilities; and on the other side computer applications posing a burden for the utility. Setting clear objectives and research will assure a utility of being on the productive side of the line. Computer systems that work well for one utility may not work well for another. Electric utilities are different in many ways with the result that software applications should be examined for applicability to a given systems operation.
Electrochemical Investigation of Copper Contamination on Silicon Wafers from HF Solutions (1996)

Copper contamination of silicon wafers from 50:1 HF solutions containing 0 to 100 ppb Cu was studied using dc electrochemical techniques. As the level of copper concentration in HF solutions increased, the corrosion current density and corrosion potential of silicon as well as the amount of copper deposition were increased. Upon addition of a nonionic surfactant, the corrosion potential, corrosion current density, and the extent of copper deposition were decreased. However, the levels of deposited copper and surface roughness were dependent on sufactant concentration. When was added to copper‐spiked HF solutions, the open‐circuit potential of silicon recovered to a value that is characteristic for silicon immersed in a mixture of and HF indicating the removal of deposited copper on silicon.

Memory for places: A navigational model in support of Marr's theory of hippocampal function (1996)

In this report we describe a model that applies Marr's theory of hippocampal function to the problem of map-based navigation. Like many others we attribute a spatial memory function to the hippocampus, but we suggest that the additional functional components required for map-based navigation are located elsewhere in the brain. One of the key functional components in this model is an egocentric map of space, located in the neocortex, that is continuously updated using ideothetic (self-motion) information. The hippocampus stores snapshots of this egocentric map. The modeled activity pattern of head direction cells is used to set the best egocentric map rotation to match the snapshots stored in the hippocampus, resulting in place cells with a nondirectional firing pattern. We describe an evaluation of this model using a mobile robot and demonstrate that with this model the robot can recognize an environment and find a hidden goal. This model is discussed in the context of prior experiments that were designed to discover the map-based spatial processing of animals. We also predict the results of further experiments.
DectICO: an alignment-free supervised metagenomic classification method based on feature extraction and dynamic selection (2015)

The alignment-free supervised classification method DectICO can accurately classify metagenomic samples without dependence on known microbial genomes. Selecting the ICO dynamically offers better stability and generality compared with sequence-composition-based classification algorithms. Our proposed method provides new insights in metagenomic sample classification.
The Photothermal Stability of PbS Quantum Dot Solids (2011)

We combine optical absorption spectroscopy, ex situ transmission electron microscopy (TEM) imaging, and variable-temperature measurements to study the effect of ultraviolet (UV) light and heat treatments on ethanedithiol-treated PbS quantum dot (QD) films as a function of ambient atmosphere, temperature, and QD size. Film aging occurs mainly by oxidation or ripening and sintering depending on QD size and the presence of oxygen. We can stop QD oxidation and greatly suppress ripening by infilling the films with amorphous Al(2)O(3) using room-temperature atomic layer deposition (ALD).
A Novel Metalloprotease in Rat Brain Cleaves the Amyloid Precursor Protein of Alzheimer's Disease Generating Amyloidogenic Fragments (1997)

The amyloid protein (Aβ or βA4) is the major constituent of amyloid plaques in the Alzheimer's disease brain. Aβ is cleaved from the amyloid precursor protein (APP) by a mechanism which is poorly understood. Cell culture studies suggest that APP may be cleaved by secretases within the late Golgi compartment. Studies performed so far have mainly used exogenous APP and synthetic peptides as substrates. For this study, a Golgi and plasma membrane-enriched fraction was isolated from rat brain and incubated at 37 °C at pH 7.2 to study the degradation of endogenous APP. The breakdown of APP was accompanied by the concomitant generation of Aβ-containing C-terminal fragments, in a time-dependent fashion. The metal ion chelators EDTA and 1,10-phenanthroline inhibited this degradation. The inhibition by EDTA was reversed by 50 μM Zn2+ but not by other metal ions. The protease activity was not inhibited by cysteine, serine or aspartic protease inhibitors nor was it inhibited by compounds which are inhibitors of known metalloendopeptidases and matrix metalloproteinases (cFP, phosphoramidon and TIMP-2). Our data suggest that a novel Zn2+-dependent metalloprotease activity associated with a Golgi and plasma membrane-enriched fraction can degrade endogenous APP to generate Aβ containing C-terminal fragments. This protease may generate amyloidogenic fragments of APP which may serve as precursors for Aβ.
Coronary artery bypass grafting with saphenous vein. (1989)

Occlusion rate of the saphenous vein is around 12-20% during the 1st year and 2-4% annually for the next 4 or 5 years. Subsequently, this rate doubles, so that at 10 years, approximately 50% of grafts become occluded due to the occurrence of graft atherosclerosis. A similar percentage of patent grafts show atherosclerotic changes at the end of the 1st decade. Sequential vein grafts probably suffer the same fate although late follow-up is lacking. Reoperation is estimated to be 30% at 10 years, as judged by angiographic criteria. The operative risk of reoperation is at least double that of primary operation; symptomatic relief appears to be of shorter duration. Recent technical changes to better preserve medial and endothelial function and to pharmacologically inhibit platelet function may lead to longer duration of the venous conduit.
Colchicine treatment of liver fibrosis. (2006)
