Sorption of Heavy Metals to the Filamentous Bacterium <i>Thiothrix</i> Strain A1 (1993)

A study was undertaken to determine the ability of the filamentous bacterium Thiothrix strain A1 to sorb heavy metals from solution. Cells of Thiothrix strain A1 were harvested, washed, and suspended in solutions of metals. After an equilibration period, biomass was separated from solution and the metal content in acid-digested cells and/or filtrates was determined by atomic absorption spectrophotometry. Sorption of nickel and zinc was very rapid; most of the sorbed metal was bound in less than 10 min. The sorption data for copper fit the Freundlich isotherm, and nickel and zinc data fit biphasic Freundlich isotherms. Sorption of both nickel and zinc was dependent on cell age. Cells harvested 24 h after inoculation sorbed approximately one-half of the amount of metal per gram cell protein than did cells harvested after 48, 72, or 96 h. Calcium and magnesium effectively competed with zinc for binding sites, whereas potassium had only a slight effect on the capacity of cells to sorb zinc. The primary mechanism of metal sorption apparently was ion exchange, because 66 to 75% of nickel or zinc could be desorbed by placing metal-laden cells in a solution of 5 mM CaCl(2). A competition experiment with nickel and zinc indicated that both metals occupied the same sorption sites. The strong chelating agents EDTA and NTA effectively prevented metal uptake, but lactate enhanced the uptake of nickel. Thiothrix strain A1 grown in nickel-containing medium had a relatively low uptake of nickel compared with uptake by resting cells suspended in a simple buffer solution.
Continuous recording of suspended solids in effluents (1962)

An account is given of a suspended-solids recorder which makes use of the principle of measuring continuously the ratio of the light transmitted by a water sample to that scattered from a beam passing through it, using a single photocell and amplifier. Two light beams, passing at right angles through the sample, are chopped at characteristic frequencies so that the component of photocell output due to transmission may later be separated from that due to scatter. The range of the instrument can be varied between 0-20 parts per million and 0-1000 parts per million. Readings are not affected by variations in incident light, sensitivity of amplifier or photocell, fouling of cell windows, colour of suspended particles or dissolved colour.
Catalytic and adsorption chemical removal of oxygen from noble gases, hydrogen and methane (1984)

The results of hydrogenation of oxygen in noble gases, hydrogen, and methane catalyzed by Pd/Al/sub 2/O/sub 3/ and Ni/Cr/sub 2/O/sub 3/ and the chemical adsorption of oxygen from these same gases by Ni/SiO/sub 2/, Ni/Cr/sub 2/O/sub 3/, CrO/SiO/sub 2/ adsorbents are reported. The possible reduction of the oxygen content of these gases by these processes to a level of 10/sup -10/ eq of O/sub 2/ is reported.
Mantener la promesa de la seguridad del ingreso en la vejez en America Latina (2004)

Many Latin American governments have radically restructured their old age income security systems, starting with Chile's 1981 pension reform. The reforms move national pension system from purely social to largely individual responsibility; from risk pooling to individual savings accounts. They maintain reduced public risk pooling features, combined with mandatory and voluntary individual private savings to finance pensions and diversify the risks to adequate income in old age-the multi-pillar approach.
Simulation tool for manpower forecast loading and resource leveling (2007)

Large scale / mega projects are lengthy complex endeavors that require significant planning by management, engineers and construction personnel to ensure the success of the project. When we examine the state of mega projects today, we are faced with a real crisis. Companies, both client and contractor, are reporting significant cost and schedule overruns. Lack of project scope definition and planning are the primary characteristics of this problem. Computer simulation is a powerful tool for analyzing complex and dynamic scenarios. It provides an appealing approach for the analysis of repetitive processes. Simulation helps decision makers identify different possible options by analyzing enormous amounts of data. Hence, computer simulation can be used effectively to analyze the resource loading and manpower requirements needed to complete a task in a given time frame, based on current progress levels. This paper discusses a special-purpose simulation (SPS) tool for optimization of manpower forecast loading and resource leveling. The simulation model is capable of optimizing resource requirements for a petrochemical project, based on standard discipline requirements and involvements. Tests of this simulation tool have produced exceptional results; currently, the system is being modified to incorporate historical data within the simulation.

Phase II Study of Erlotinib in Patients With Advanced Biliary Cancer (2006)

Results suggest a therapeutic benefit for EGFR blockade with erlotinib in patients with biliary cancer. Additional studies with erlotinib as a single agent and in combination with other targeted agents are warranted in this disease.
Concerning “Sprechgesang” (1946)

In part III of Schönberg's Gurrelieder there is a section, Des Somtnenvindes wilde Jagd , that is described as a “melodrama” and that constitutes the only appearance in the work of the character listed among the soloists as “The Speaker.” The words of this number are written under what would appear to be a normal vocal line (though perhaps of rather unusually simple nature), except that crosses are used instead of note-heads: There are no directions in the score as to how the part is to be rendered.
석탄 비산재로 합성한 Na-A형 제올라이트에 의한 구리와 아연 이온의 동역학적 흡착 특성 (2011)

The adsorption performance of cupper and zinc ions(Cu2+ and Zn2+) in aqueous solution was investigated by an adsorption process on reagent grade Na-A zeolite(Z-WK) and Na-A zeolite (Z-C1) prepared from coal fly ash. Z-C1 was synthesized by a fusion method with coal fly ash from a thermal power plant. Batch adsorption experiment with Z-C1 was employed to study the kinetics and equilibrium parameters such as initial metal ions concentration and adsorption time of the solution on the adsorption process. Adsorption rate of metal ions occurred rapidly and adsorption equilibrium reached at less than 120 minutes. The kinetics data of Cu2+ and Zn2+ ions were well fitted by a pseudo-second-order kinetics model more than a pseudo-first-order kinetics model. The equilibrium data were well fitted by a Langmuir model and this result showed Cu2+ and Zn2+ adsorption on Z-C1 would be occupied by a monolayer adsorption. The maximum adsorption capacity(qmax) by the Langmuir model was determined as Cu2+ 99.8 mg/g and Zn2+ 108.3 mg/g, respectively. It appeared that the synthetic zeolite, Z-C1, has potential application as absorbents in metal ion recovery and mining wastewater.
Optimal Design of Slider Air-Bearing for Discrete Track Recording Technology (2009)

This paper suggests a design methodology for slider air bearings over a discrete track recording (DTR) disk using a simplified static analysis including the flying-height (FH) loss equation instead of a computationally expensive, time consuming transient dynamic analysis. Because a slider over a DTR disk has different flying characteristics than a slider over a continuous track recording (CTR) disk, the design of the slider requires modification. However, it is challenging to dynamically simulate slider air bearings over a DTR disk. Furthermore, it is nearly impossible to design the slider using an expensive dynamic analysis as a solver. Therefore, we define the flying characteristics of the DTR slider as a function of that of the CTR slider by using the FH loss equation based on averaged flow effect. A design optimization problem is formulated to meet the design requirements of the DTR slider, which include target FH, FH flatness, altitude FH drop, pitch and roll angle ranges, and altitude pitch drop. The design problem is changed to an inverse problem using a conventional static analysis for a CTR disk instead of an expensive dynamic analysis for a DTR disk. Simulation results showed that the optimally designed DTR slider can meet the target FH while satisfying all design requirements over the entire recording band.
Spinal cord injury in the monkey (1979)

We have investigated the effectiveness of surface cord cooling in reducing spinal cord temperature with respect to the rate of cooling and the temperature gradient within the spinal cord parenchyma. Another question of some practical importance if spinal cooling is to be used clinically is that of the temperature within the spinal cord as a function of the dura being intact or open. In five monkeys, a laminectomy was carried out at T-10 and an impact injury of 350 g-cm force was applied to the spinal cord with the dura intact. Hypothermic perfusion with Elliott's B solution (artificial cerebrospinal fluid) was started, and we measured temperatures in the spinal cord with a thermistor probe mounted on a stereotactic drive. A series of measurements were made with the dura intact and the measurements were then repeated with the dura open. For comparison, we also recorded temperatures in one animal that had not been cord-injured. The rate of cord cooling was rapid during the first 3 minutes of hypothermic perfusion, after which there was a slight further reduction in cord temperature; a low level plateau of 6.7° C was reached within 21 minutes after the start of cooling. The temperature gradient at varying depths of the spinal cord was approximately 6° C (3.8° C at the posterior surface to 10.1° C in the deepest portion of the spinal cord), representing a temperature gradient of 1.3° C/mm of cord tissue. Transmission of the cooling effect from perfusate to the spinal cord was not appreciably affected by the dura being intact or open. (Neurosurgery, 5: 583-587, 1979)
Propagating and Standing Sawtooth Waves (1969)

The well-known theory for energy dissipation in weak shock waves is applied to the case of propagating and standing acoustic waves of finite amplitude. The known results for the decay of plane, cylindrical, and spherical waves propagating in a fluid are obtained by means of a simple technique previously used by Rudnick [J. Acoust. Soc. Amer. 25, 1012 (L) (1953)] and based on the assumption that the waves are of the sawtooth type with a weak discontinuity each wavelength. The same technique is then applied to large-amplitude resonant oscillations in tubes, assuming that the acoustic field can be represented by two sawtooths traveling in opposite directions inside the tube. These calculations are of a very simple nature and yield solutions that compare favorably with results obtained by more rigorous techniques.
Renewable polyamides and polyurethanes derived from limonene (2012)

The addition of cysteamine hydrochloride to (R)-(+)- and (S)-(−)-limonene is described as a versatile and effective way to obtain new amine functionalized renewable monomers for polyamide and polyurethane synthesis. Thus, through different combinations, limonene, fatty acid, as well as Nylon 6,6 copolymers were prepared and their structure–thermal property relationships were studied. GPC and DSC characterization revealed that these monomers can be used to synthesize polyamides with good and adjustable thermal properties. Moreover, the synthesized diamines have successfully been transformed into dicarbamates via a phosgene-free route and their behaviour in polycondensation was studied. A number of linear renewable polyurethanes, from amorphous to semi-crystalline, were thus obtained via an isocyanate-free route, demonstrating new potential uses for these renewable resources. Also these polyurethanes were characterized in detail and their thermal properties were studied.
Carry delayed save adders for computing the product <i>A · B</i> modulo <i>N</i> in log <sub>2</sub> <i>N</i> steps (1990)

The design of a new modular multiplier which uses carry delayed save adders is presented. The system makes use of the techniques of sign estimation and digital division from the right in order to produce the product in n steps. The inputs to the device can be in carry save, delayed save or standard binary and the output is produced as a delayed save integer. This means that the system is ideal for use in situations where the product produced by the previous operation is then fed back to be re-multiplied, e.g. repeated squaring and exponentiation
Security Research of a Social Payment App (2014)

We have performed a security audit of Venmo, a social payments application. We were interested in analyzing Venmo because of its position at the intersection of pay-ment processing (which must be implemented securely) and social networking. We think it is important to know if secure payment is possible in a social networking envi-ronment. As such, we searched for both technical and social vulnerabilities, in addition to reverse-engineering the private API used by Venmo’s apps. We looked for bugs that would allow us to steal money from others, and also ways to trick people into voluntar-ily giving money to the wrong person. We found several issues, including some which could allow some adversaries to steal other users ’ money, and some which leak infor-mation which should not be public. We recommend that Venmo they improve their user interface, remove certain user actions, and change their default privacy settings.

Stakeholder perceptions of older adult mental health day services in Huddersfield (2005)

This report presents the findings of a qualitative inquiry into the purposes, processes and outcomes of NHS day services for older adults with mental health problems in Huddersfield. The study canvassed a variety of viewpoints amongst patients, carers and staff as a first step to developing further research into NHS and social day services for this patient group. All interviewees perceived help with mental health problems as the main purposes of attendance. Other views diverged: patients and carers stressed help with physical health problems and other practical assistance whilst staff chose process-related variables such as assessment and monitoring. The divergence between patients, carers and staff was even stronger when we asked about the processes and the perceived outcomes of these facilities. These different views of purposes, processes and outcomes provide a starting point for developing further exploratory and evaluative research of different NHS day services for this patient group. This may also be useful in future comparisons between NHS and social services day provision.
A Regularized Framework for Sparse and Structured Neural Attention (2017)

Modern neural networks are often augmented with an attention mechanism, which tells the network where to focus within the input. We propose in this paper a new framework for sparse and structured attention, building upon a smoothed max operator. We show that the gradient of this operator defines a mapping from real values to probabilities, suitable as an attention mechanism. Our framework includes softmax and a slight generalization of the recently-proposed sparsemax as special cases. However, we also show how our framework can incorporate modern structured penalties, resulting in more interpretable attention mechanisms, that focus on entire segments or groups of an input. We derive efficient algorithms to compute the forward and backward passes of our attention mechanisms, enabling their use in a neural network trained with backpropagation. To showcase their potential as a drop-in replacement for existing ones, we evaluate our attention mechanisms on three large-scale tasks: textual entailment, machine translation, and sentence summarization. Our attention mechanisms improve interpretability without sacrificing performance; notably, on textual entailment and summarization, we outperform the standard attention mechanisms based on softmax and sparsemax.
A (3H)2-Deoxyglucose Method for Comparing Rates of Glucose Metabolism and Insulin Responses Among Rat Tissues In Vivo: Validation of the Model and the Absence of an Insulin Effect on Brain (1984)

In 1980 we described an in vivo method for estimating the rate of glucose uptake among selected tissues during an acute insulin response. The method was based upon the same principles as Sokoloff's 2-deoxyglucose (2DG) method. We now report further examination of the basic assumptions of the model and validation of its general applicability by comparing the response of brain and other tissues to prolonged insulin infusion (while glucose is held constant) with their response to a single injection of insulin. The method provides a reproducible estimate of relative insulin response in any tissue that can be anatomically separated at death. Tissues that are minimally sensitive to insulin such as spleen, lung, skin, and gut do not display increments in the calculated value for net rate of tissue uptake of 2DG. Insulin-sensitive tissues display increased rates of uptake that are characteristic for each specific tissue, ranging in magnitude from 1.7- to 17.9-fold over basal among an array of insulin-sensitive tissues. The duration of a unit response to a sub-maximal dose of insulin also varied among the tissues, persisting for 20-30 min after plasma insulin had returned to basal in heart and for 10-20 min in the other insulin-sensitive tissues. The method provides a reproducible measure of glucose metabolism in vivo and has been validated as a means of quantifying relative insulin sensitivity among the peripheral tissues. During steady-state conditions with plasma glucose held constant, brain glucose metabolism was unaffected by a 60-min infusion of insulin.

The Communication of Process Based on StreamSocket of Winsock (2010)

Socket is the foundation of the communication.It is the basic operating unit that supports TCP/IP protocol at network communication.Socket is the end that the process of the different host computer communicates each other.A socket is an end of communication.Socket exists in communication domain.Socket exchange data with the socket of the same domain.Windows Sockets criterion supports the single communication domain that is also named Internet domain.Various kinds of processes use this domain and the groups of Internet protocol to communicate with each other.Stream Socket provides data stream serve that is double-oriented and has no repetition and record boundary.It applies to the processing of large data.Thus the communication of different processes can be realized in the network environment.
[The evaluation of the detoxication function of the kidneys by the clearance of middle molecules]. (1997)

The detoxifying function of the kidneys was examined in 56 patients with renal diseases. The function was assessed from the clearance of medium-mass molecules in relation to the total water content in the body. Medium-mass molecules in the serum and urine were assessed by the method based on direct UV spectrophotometry. A correlation has been revealed between the content of medium-mass molecules, serum creatinine, clearance of creatinine, and the detoxifying function of the kidneys. The method is simple, reliable, and does not require expensive reagents.
A Software Package for the Numerical Integration of ODEs by Means of High-Order Taylor Methods (2005)

Abstract This paper revisits the Taylor method for the numerical integration of initial value problems of Ordinary Differential Equations (ODEs). The main goal is to present a computer program that outputs a specific numerical integrator for a given set of ODEs. The generated code includes a function to compute the jet of derivatives of the solution up to a given order plus adaptive selection of order and step size at run time. The package provides support for several extended precision arithmetics, including user-defined types. The paper discusses the performance of the resulting integrator in some examples, showing that it is very competitive in many situations. This is especially true for integrations that require extended precision arithmetic. The main drawback is that the Taylor method is an explicit method, so it has all the limitations of these kind of schemes. For instance, it is not suitable for stiff systems.
