Purification of Trypsin by Affinity Chromatography with Sulphamethoxazolum Ligand (1996)

Pharmaceuticals have already been studied comprehensively both in their physico-chemical properties and their biological effect. Most of these compounds are chemically synthesized and less susceptible to degradation by micro-organism or suffering from solvent effect compared with the bio-active substances. Affinity chromatographic columns composed of pharmaceutical compounds as the ligand should have advantages such as long life, low cost and low toxicity. This paper describes the preparation of sulphamethoxazolum immobilized on silica as the column packing and the study of its interactions with proteins and enzymes. It was found that this material showed an affinity specific to trypsin with a dissociation constant of around 10(-6) M. The enzymatic activity of commercial trypsin can be increased by a factor of ten after purification with such a column.
A model of the formation of branched polymethyl methacrylates (2009)

A model of formation of macromolecules in the form of a crown of a tree was suggested to describe the character of branching and architecture of branched macromolecules synthesized by radical copolymerization of a monomer with a bifunctional monomer-branching agent in the presence of a chain transfer agent. The branch representing a polymer chain with included branching agent units was accepted as the main structural element of macromolecules. Model parameters were determined from the kinetic characteristics of copolymerization, such as reagent ratio and growth rate and chain transfer constants. Branching and architecture parameters of branched polymethyl methacrylates synthesized at various monomer: branching agent: chain transfer agent ratios were calculated

New CMOS floating voltage-controlled resistor (1986)

A new CMOS floating voltage-controlled resistor for continuous-time filtering applications is described. The value of the resistance simulated by this circuit is independent of the threshold voltage of the transistors. This allows us to obtain a larger input range and also minimises the effects of threshold voltage mismatches and substrate noise. These improvements are obtained at the expense of a higher sensitivity to mismatches in the W/L ratios of the transistors.
Annealing Effect of ZnO Seed Layer on Enhancing Photocatalytic Activity of ZnO/TiO<sub><b>2</b></sub>Nanostructure (2013)

Zinc oxide (ZnO)/titanium dioxide (TiO 2 ) nanorods have been synthesized via a hydrothermal method for ZnO nanorods and an electron-beam deposition for TiO 2 nanorods. This work examined the effect of annealing ZnO seed layer on the photocatalytic activity of the ZnO/TiO 2 nanorods which was determined from photodecomposition of methylene blue under UV irradiation. The photocatalytic activity of the ZnO/TiO 2 nanorods was improved with increasing annealing temperature of the seed layer from 300°C to 500°C. Annealing the seed layer at 500°C showed the best photocatalytic activity resulting from high UV absorption ability, a large surface area with flower structure and copious oxygen defects which promote separation of electron-hole pairs reducing electron recombination. The prepared nanorods were characterized by field emission-scanning electron microscopy (FE-SEM), X-ray diffraction (XRD), photoluminescence (PL), and UV-visible spectroscopy.
Building Information Modeling Based Integration and Visualization for Facilities Management (2012)

Facilities managers need to identify and understand deterioration/failure causes-effect patterns in order to prepare preventive maintenance plans. However, this task is difficult because of the complex interaction between different building components and their operational conditions. In spite of the availability of advanced Computerized Maintenance Management Systems (CMMSs), these systems focus on the data management aspects (i.e. asset inventory, work orders and resource management) and lack the functions necessary to analyze the collected data in order to identify deterioration/failure patterns. Standardization based on Building Information Modeling (BIM) provides new opportunities to improve the efficiency of Facilities Management (FM) by sharing and exchanging building information between different applications throughout the lifecycle of the facilities. This research proposes the integration of FM related data from different sources such as CMMS and BIM through adding the CMMS inspection and maintenance data to the BIM database. This integration, in addition to defined logical and spatial relationships between components and spaces, is used to find the cause-effect relationships through a BIM-based visual analytics. This method facilitates heuristic problem solving and helps to increase the quality of O&M phase. It is also proposed to integrate CMMS, BIM, video, and Real Time Location System (RTLS) data using Augmented Reality (AR) techniques to visualize construction and renovation operations and to retrieve information about the time, space, and related activities to visualize construction and renovation operations. Several case studies are implemented and tested to show the feasibility of the proposed methods.
Predictive direct torque control strategies of induction motor based on area voltage vectors table (2004)

In this paper, the torque ripples in low speed range of conventional direct torque control are discussed in detail, and a new vector selection table based on area voltage is proposed to control the torque and flux. In this case, two predictive control schemes of torque and flux are presented to reduce torque ripples and improve the steady and dynamic performance. Finally, simulations and experiment results are given to show the validity and the advantages of the proposed predictive schemes based on area voltage vector table.
Automated Oxidase-Coupled Amperometric Microsensor with Integrated Electrochemical Actuation System for Continuous Sensing of Saccharoids (2006)

Recent developments for biosensors have been mainly focused on miniaturization and exploratory use of new materials. It should be emphasized that the absence of an "in-situ self-calibration/diagnosis technique" that is not connected to an external apparatus is a key obstacle to the realization of a biosensor for continuous use with minimum attendance. To address this deficiency, a needle-type biosensor system with fully automated operations is being developed, in which an oxidase-coupled amperometric sensor with oxygen depleting/generating actuator is interfaced with an electrochemical instrument and a perfusion system. Labview virtual instrument has been also developed to oversee the automatic control of the prototype sensor. Using the proposed system, a large amount of data can be rapidly collected for more effective sensor characterization and more advanced sensor designs. Autonomous and continuous sensing and self-calibration with minimal human intervention is also envisioned
Transjugular percutaneous Inoue balloon mitral commissurotomy in a patient with inferior vena cava obstruction after liver transplantation (2003)

Percutaneous transvenous mitral commissurotomy was performed successfully via the transjugular approach in a patient with severe rheumatic mitral stenosis and obstruction of the inferior vena cava due to prior liver transplantation. This case demonstrates the advantage of the jugular approach in patients with difficult anatomy.
Antifatigue activity of water extracts of Toona sinensis Roemor leaf and exercise-related changes in lipid peroxidation in endurance exercise (2009)

This study evaluated the antifatigue activity of water extracts of Toona sinensisRoemor leaf (ETL) and exercise-related changes in lipid peroxidation in swimming exercise of mice. Male Kunming mice were studied by being divided into four groups (n = 30 mice per group): low, medium, high-dose ETL treated groups and control group. Swimming endurance experiment were conducted after 21 days of ETL supplementation and the result showed that ETL was found to possess an antifatigue activity, extend the swimming time of the mice, prevent the increase in lactic acid, increasing content of liver and muscle glycogen of mice and may decrease the contribution of exercise-induced oxidative stress.

Dissolution of Cystine Calculi by Pelviocaliceal Irrigation with B-Penicillamine (1980)

We report on a cystinuric patient in whom unilateral hydronephrosis developed as a result of massive renal stone formation owing to non-compliance of systemic penicillamine therapy. At operation a large number of calculi could not be removed for technical reasons. After successful in vitro dissolution of 1 calculus using a 0.5 per cent solution of D-penicillamine at pH 8.0 the same solution was used to irrigate the renal collecting system via a nephrostomy tube. After 2 months of daily irrigations, which were decreased to 2 times a week for another 2 months, all the stones appeared radiographically to have disappeared. At followup 2 years after removal of the nephrostomy tube the patient is on regular systemic therapy with no evidence of residual or recurrent stone formation.
Polarization in an Aluminum Reduction Cell (1956)

A new method, which combines the technique of current reversal with the use of an a‐c bridge, is presented for determining polarization in an aluminum reduction cell. Polarization was found to be composed of two parts. One part had a very short time constant and the other, a very long time constant.
All-values symbolic execution (2012)

This paper discusses and exemplifies our ideas on all-values symbolic execution, an alternative strategy to the traditional all-paths style of symbolic execution. All-values symbolic execution focuses on enumerating the (symbolic) values that may derive from the symbolic execution of program statements. It exploits program dependencies to optimize the symbolic execution of those statements that can be executed with the same symbolic inputs on multiple (up to infinite) paths. Although a fully working implementation and a thorough evaluation are yet to come, this paper illustrates with simple, but representative examples that the proposed technique can boost the efficiency of symbolic execution, and suite interesting new applications.
A Low-Power 4-PAM Transceiver Using a Dual-Sampling Technique for Heterogeneous Latency-Sensitive Network-on-Chip (2015)

This brief presents a four-level pulse-amplitude modulation (4-PAM) transceiver for latency-sensitive network-on-chip (NoC) applications. The proposed source-synchronous PAM transceiver uses a novel encoder/decoder and dual-sampling technique that transmits and receives two data streams through a shared single-ended channel simultaneously. A conventional PAM transceiver for heterogeneous NoCs is sensitive to a possible latency skew between on-chip intellectual properties during encoding/decoding multiple PAM signals. To mitigate this problem, a dual-sampling technique that makes the link insensitive to PAM latency skews is used to transfer data signals reliably. The proposed 4-PAM transceiver is designed and fabricated using the 130-nm CMOS technology at a 1.2-V supply. The proposed transceiver operates at 6 Gb/s/pin with a power efficiency of 0.7 pJ/b/pin and with a 0.13-mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> die area.

Effect of light-emitting diode vs. fluorescent lighting on laying hens in aviary hen houses: Part 1 – Operational characteristics of lights and production traits of hens (2015)

Light-emitting diode (LED) lights are becoming more affordable for agricultural applications. Despite many lab-scale studies concerning impact of LED on poultry, little research has been documented under field production conditions, especially for laying hens. This 15-month field study was carried out to evaluate the effects of LED vs. fluorescent (FL) lights on laying hens (Dekalb white breed) using 4 (2 pairs) aviary hen houses each at a nominal capacity of 50,000 hens. The evaluation was done regarding operational characteristics of the lights and hen production traits. The results show that spatial distribution of the LED light was less uniform than that of the FL light. Light intensity of the LED light decreased by 27% after 3,360 h use but remained quite steady from 3,360 to 5,760 h use. Eleven out of 762 (1.44%) LED lamps (new at onset of the study) in the 2 houses failed during the 15-month experiment period. The neck area of the LED lamp was hottest, presumably the primary reason for the lamp failure as cracks were noticed in the neck region of all failed LED lamps. No differences were observed in egg weight, hen-day egg production, feed use, and mortality rate between LED and FL regimens. However, hens under the FL had higher eggs per hen housed and better feed conversion than those under the LED during 20 to 70 wk production (P < 0.05). Hens under the LED tended to have less feather uniformity and insulation than those under the FL (P < 0.05). Moreover, hens under the LED showed a larger median avoidance distance than those under the FL at 36 wk age (P < 0.05), indicating that hens under the LED were more alert; but no difference at 60 wk age. More comparative research to quantify behavioral and production responses of different breeds of hens to LED vs. FL lighting seems warranted.
Pseudorandom Arrays for Built-In Tests (1986)

Parallel pseudorandom sequences for use in built-in test are discussed. The two-dimensional nature of these sequences-makes it natural to consider the resulting binary arrays. Some of the desired properties of such arrays are discussed, as well as some of the problems. Generators for such arrays are described. A conventional LFSR with parallel output is shown to be a poor choice for such a generator. Several compact generators are described, which are shown to be compromises between complexity and varying degrees of implementation of the desired properties in the resulting sequences. One of the compact generators produces sequences which have the desired properties for built-in tests.
Operational strategies, monitoring and control of heterologous protein production in the methylotrophic yeast Pichia pastoris under different promoters: A review (2006)

The methylotrophic yeast Pichia pastoris has been widely reported as a suitable expression system for heterologous protein production. The use of different phenotypes under PAOX promoter, other alternative promoters, culture medium, and operational strategies with the objective to maximize either yield or productivity of the heterologous protein, but also to obtain a repetitive product batch to batch to get a robust process for the final industrial application have been reported. Medium composition, kinetics growth, fermentation operational strategies from fed-batch to continuous cultures using different phenotypes with the most common PAOX promoter and other novel promoters (GAP, FLD, ICL), the use of mixed substrates, on-line monitoring of the key fermentation parameters (methanol) and control algorithms applied to the bioprocess are reviewed and discussed in detail.
Detection of bushing insulation defects by diagnostic monitoring (2016)

Comparative diagnostic tests were performed in the laboratory on oil-impregnated paper and resin-bonded paper bushings. The bushings have undergone long-term AC tests and insulation capacitance, dissipation factor and partial discharge were continuously monitored. A 110 kV oil impregnated paper bushing with artificially induced defects was tested. The effect of insulation contamination and oil leakage on the bushings' insulation condition were investigated with on-line monitoring. With concern to the resin bounded paper bushing, a new 52 kV unit with design flaws was tested. After the tests, the bushing was opened and the capacitive layers were inspected individually. The results are presented in the paper. A correlation between the monitored values and the bushing condition can be done based on the performed measurements. This information would support the field engineers to set realistic threshold limits of the monitored parameters and for asset managers to establish appropriate condition-based maintenance strategies.
Metal-foam interface stability during the filling of lost foam moulds with aluminium alloys (2011)

Aluminium Lost Foam castings were made using gravity and counter-gravity filling techniques. Tensile strength was found to be most uniform in those castings which had been filled slowly from the bottom and where the metal front had remained stable throughout filling sequence. Pores containing carbon deposits were found on the fracture surfaces of all the castings made and this suggested that the defect was caused by polymer entrapment. A Saffman-Taylor instability was observed at the interface between Hg and a viscous glucose syrup which were contained in an analogue, that was used simulate the casting of Lost Foam moulds at room temperature. The liquid degradation products of the polystyrene patterns were also found to be viscous, although this was reduced by treatment with Br. Under the same conditions of temperature and velocity, the interface observed during the filling of a Br-treated pattern was planar whereas that of an untreated pattern was unstable. This demonstrated not only that the interfacial instability entrapped polymer degradation products, which adversely affected casting quality, but was probably of the Saffman-Taylor type.
HARVESTMEN RECORDS FROM THE KÖPRÜLÜ CANYON NATIONAL PARK, ANTALYA (ARACHNIDA: OPILIONES) (2014)

In this study, a total of 91 harvestmen specimens were collected from various localities of the Koprulu Canyon National Park between 2005 and 2006. Adult individuals as a result of a systematic evaluation of the collected and bioecological aspect, four species in four genera in two families were determinated. Description, morphology, habitat, ecology and geographical distribution of the species were examined. At the end of this study, in Phalangiidae, Lacinius ephippiatus (CL Koch, 1835), Odiellus lendli (Soerensen 1894), Zacheus crista (Brulle, 1832), and in Dicranolasmatidae, Dicranolasma scabrum (Herbst, 1799) have been identified. Among the species Odiellus lendli is a new record for the opilionid fauna of Turkey. Together with Odiellus lendli the species number that recorded from Turkey raised to 70.
The Accident at Chernobyl Unit 4 in the Ukraine—April 1986 (1988)

Abstract On April 26, 1986, the worst accident in the history of commercial nuclear power generation occurred at the Chernobyl Nuclear Power Station some 60 miles north of Kiev in the Ukraine, This paper describes the sequence of events that occurred and the consequences of the accident. There was extensive damage to the Unit 4 reactor and the building that housed it. Some 31 people died as a result of the accident, either directly or as a result of receiving lethal radiation doses. A significant release of fission products occurred, contaminating land around the station and requiring the evacuation of around 135,000 people from their homes. The radioactive cloud generated over several days was carried by winds to all parts of Europe, where there was a varying degree of public concern. The contamination resulted in restrictions on the consumption of meat and vegetables. The latent health effects are, however, unlikely to be statistically significant when viewed against the normal mortality rate over the next 40 years. Although there were gross violations by the operators, the primary cause of the accident can be attributed to inherent design shortcomings in the RBMK reactor type, which is unique to the Soviet Union. The Russians have said that the accident is not possible in any commercial reactor operational outside the USSR.
Improved triple lumen all purpose drains and their care and management. (1983)

A triple lumen all purpose drain has become well established over the past decade as an all purpose drain. It permits either overflow or suction (closed or sump) drainage, aspiration for the taking of cultures or analysis of fluid, irrigation either continuous or intermittent, and the instillation of medications. Further improvements have been made in the drain in the quest for the ideal surgical drain. It is now made of silicone, has a radiopaque stripe, a suture sleeve, a triple lumen molded connector with a drainage tube, irrigation port, bacterial filter, and stoppers. The advantages of these additions are presented. In addition, the drain is being made in two sizes; the smaller one is indicated in pediatric, breast, plastic, head and neck, and other procedures. The care and management of these drains is discussed.

Contactless energy transfer using planar printedcircuit board windings (2001)

An energy transfer circuit is proposed which employs a pair of neighbouring printed circuit board windings as a contactless energy transfer device, thereby making it amenable to low-profile designs and suitable for applications in which stringent requirements for height, space, and reliability have to be met.
