One of the most important depassivation mechanisms of steel reinforcement in concrete is that caused by the neutralisation of the cement matrix. In this work, a summary of the development of a model for the carbonation of cementitious matrixes (UR-CORE) is presented. On one hand, in-situ monitoring of the changes that take place in the phase composition of cement pastes during accelerated carbonation (100% CO2) for different binders, is reported, by taking Neutron Diffraction patterns in parallel with the carbonation experiments. The variation of the intensity of chosen reflections for each phase along the experiment supplied data, in real time, for fractional conversion of different phases. On the second hand, fitting of these results allowed to make a quantitative approach to the kinetics of the carbonation of the different phases, and develop the UR-CORE model that is based on the principles of the "unreacted-core" systems, typical of chemical engineering processes.

The necking phenomena and molecular orientation of nylon-6 filament yarn in an industrial cold drawing process were observed by determining the value of birefringence (Δn) of drawn filament yarn. Further, the relation between the properties of drawn filament yarns and the drawing conditions were considered. The following results are obtained : (1) When the yarn is drawn under the industrial draw ratio 4.0, the value of birefringence (Δn) of the yarn passed through feed rollers becomes maximum at the end of the necking point, close to the feed roller. (2) Then, Δn is in equilibrium where the yarn speed is equal to the drawing roller speed. (3) Further, Δn becomes smaller between the drawing roller and the winding bobbin. (4) When yarn is wound under any tension, Δn becomes greater with the lapse of time and reaches to the constant value. (5) Δn increase asymptotically with the lapse of time when the yarn is drawn under the draw ratio 3.0, but Δn is approximately constant under the draw ratio 3.5, 3.6 and 4.0. The values of Δn of filament yarns drawn at the high drawing temperature are greater than those of yarns drawn at the low drawing temperature. (6) Variations of Δn under different drawing condition, e.g., draw ratio, humidity in a drawing chamber, etc., are also observed. (7) The determination of yarn properties under different drawing condition shows that the orientation behaviour in drawing process is related to the yarn properties. (8) The drawing tension, molecular orientation and crystalization under different draw ratio are determined and their behaviours are also analysed. (9) An attempt is successfully made to estimate the winding tension on a draw-twisting bobbin by determining Δn of the wound filament yarn.

We have developed appropriate and excellent catalysts for direct DME synthesis. The catalysts, Cu-Zn/Al2O3 catalysts prepared by the sol-gel method, produce DME with high DME activity and high DME selectivity under milder reaction temperature and pressure compared with the usual direct DME synthesis catalysts (mixed catalysts of methanol synthesis catalysts and methanol dehydration catalysts). It will be the reason why the methanol synthesis active sites (copper) and the methanol dehydration active sites (alumina) on the sol-gel Cu/Al2O3 catalysts exist closer than those of the mixed catalysts.


The SARS‐CoV‐2 variant Omicron emerged in late 2021. In British Columbia (BC), Canada, and globally, three genetically distinct subvariants of Omicron, BA.1, BA.2, and BA.5, emerged and became dominant successively within an 8‐month period. SARS‐CoV‐2 subvariants continue to circulate in the population, acquiring new mutations that have the potential to alter infectivity, immunity, and disease severity. Here, we report a propensity‐matched severity analysis from residents of BC over the course of the Omicron wave, including 39,237 individuals infected with BA.1, BA.2, or BA.5 based on paired high‐quality sequence data and linked to comprehensive clinical outcomes data between December 23, 2021 and August 31, 2022. Relative to BA.1, BA.2 cases were associated with a 15% and 28% lower risk of hospitalization and intensive care unit (ICU) admission (aHRhospital = 1.17; 95% confidence interval [CI] = 1.096–1.252; aHRICU = 1.368; 95% CI = 1.152–1.624), whereas BA.5 infections were associated with an 18% higher risk of hospitalization (aHRhospital = 1.18; 95% CI = 1.133–1.224) after accounting for age, sex, comorbidities, vaccination status, geography, and social determinants of health. Phylogenetic analysis revealed no specific subclades associated with more severe clinical outcomes for any Omicron subvariant. In summary, BA.1, BA.2, and BA.5 subvariants were associated with differences in clinical severity, emphasizing how variant‐specific monitoring programs remain critical components of patient and population‐level public health responses as the pandemic continues.


The quasi-normal scale elimination (QNSE) theory is an analytical spectral theory of turbulence based upon successive elimination of small scales of motion and calculating ensuing corrections to the viscosity and diffusivity. The main results of the theory are analytical expressions for eddy viscosity, eddy diffusivity, and kinetic energy and temperature spectra. Partial scale elimination yields a subgrid-scale representation for large-eddy simulations, whereas the elimination of all fluctuating scales is analogous to the Reynolds averaging. The scale-dependent analysis enables one to put processes on different scales at the spotlight and elucidate their contributions to eddy viscosities and eddy diffusivities. In addition, the method traces the modification of the flow with increasing stratification and recovers growing anisotropy and the effect of the internal waves. The QNSE-based Reynolds-averaged models present a viable alternative to conventional Reynolds stress models. A QNSE model of this kind was tested in the numerical weather prediction system HIRLAM instead of the existing reference Reynolds stress model. The performance of the QNSE model was superior in all simulations where stable stratification was noticeable.


The purpose of this study is to examine the principles and mechanisms of a unique exercise method known as Tension Stress Trauma Releasing Exercises (TRE) and to explore whether TRE relieves adult state anxiety. Physical tremors are generally physical symptoms experienced during or immediately after experiencing excessive tension, stress, and trauma. In this study, TRE was briefly introduced and a pilot study was conducted first before starting to verify the effect in earnest by applying a structured experimental design.The subjects of the study were 25 graduate students who participated in the training. The condition anxiety test was performed before and after training for the group who received 3 hours of TRE training, and the paired-t test was applied for data processing. As a result of the study, it was found that TRE body tremor exercise reduces state anxiety. The results of this study indicated that TRE tremors have an anxiety reduction effect and suggested the possibility of therapeutic values for various physical and psychological difficulties.


Carbon fiber-reinforced epoxy composite has become the material of choice in highperformance bicycle frames. Compared to the traditional frame building materials (steel, aluminum, and titanium alloys), composites offer greater specific strength, modulus, and vibration damping; as well as the ability to form aerodynamic tube profiles, and finely tuned ride characteristics by varying fiber modulus and stacking sequence throughout the frame. However, bicycle frames are often subject to unintended impacts -oriented out-of-plane with respect to the tube walls -which frequently result in structural damage of the laminated composite. Fortunately, this damage is often repairable. In this work, a single case study demonstrates how the principles of bonded structural repair developed by the aviation composites industry can be applied to bicycle frames and other thin-walled, tubular composite structures. The repair process is documented step-by-step with explanations of the underlying theory, as well as attention to practical aspects.


This paper systematically analyzed the change of hydrogeological hazard environment happened during recent years in Hebei Province.It is believed that in the range of decades or hundred of years, human action played the key role in the dramatic change of hydrogeological environment. Technological and engineering adjustments to reallocate surface water and the development of groundwater resource have on one hand obtained significant achievements, but on the other hand, accumulated the sideeffects into hazards or even led to disasters. To reduce the damage caused by hydrological hazards and achieve the aim of sustainable development, human beings should keep the order of natural while make use of natural resources to develop social economy.


Malathion is an organophosphate pesticides commonly used to eradicate the pest of agricultural crops. It is routinely used to protect the ornamental and home gardening plants. Malathion is found in market by its trade name called cythion. In Indian scenario farmers and spray men use pesticide in their fields ignoring its toxicological effects. The main target organs of any toxicant in human body are liver and kidney.Present study is based on the effects of different dose of Malathion on blood biochemical parameter like blood sugar, blood urea, creatinine and bilirubin. These four parameters are used to observe the behavior of liver and kidney in albino rats. Four doses of Malathion has been selected as 25 mg, 50mg, 75mg and 100mg per kilogram body weight per day for 7 days and 15 days of treatment. Findings indicate that at normal condition the value of sugar was 121.54 +14.44 mg/dl , blood urea 41.27 + 3.13 mg/dl , blood bilirubin 0.76 + 0.10 mg/dl and value of creatinine was observed as 0.85 + 00.52 mg/dl. with different doses of Malathion after 7 and 15 days the value of blood sugar significantly decreases upto 78.52 + 10.25 mg/dl at higher dose while blood urea value significantly increased up to 50.88+4.8 mg/dl, the value of creatinine significantly increased 1.05 + 0.18 mg/dl and bilirubin also increased significantly 2.20 +0.64mg/ dl. The fluctuation in parameter represents the abnormal behavior of liver and kidney of albino rats due to the toxicity of pesticide.


We detect atomic parity violation (APV), by using stimulated emission, in the form of a chiral optical gain of a cesium vapor on the 7S-6P3/2 transition, consecutive to linearly polarized 6S-7S excitation. The method relies on a pump-probe scheme in which the excited 7S state is populated, in zero B-field, by an intense, pulsed excitation beam, with a linear polarization Eex and a wave vector k parallel to the applied electric field E. The atoms are then probed by a second, collinear pulsed laser beam, tuned to resonance with the 7S-6P3/2 transition. The probe beam is amplified by stimulated emission and its linear polarization Epr undergoes a small change of direction, due to a linear dichroism arising from the presence of the pseudoscalar PV term (Eex.Epr)[ (Eex X Epr). E] in the gain, associated with a tilt theta^{pv} of the gain eigen-axes with respect to the plane of symmetry (Eex, k). The tilt of typically 1µrad, theta^{pv} = - Im E1pv/ beta.E, odd under E- reversal, is the relevant APV quantity. We measure it by balanced-mode two-channel polarimetry, with dedicated real-time calibration. We have demonstrated the validity of this detection method by performing a measurement of expected sign and magnitude with a 9% accuracy, now improved by more than a factor of two, thanks essentially to a dichroic polarization-tilt magnifier. Rotational symmetry around the common pump-probe axis is used to reduce systematic effects. Latest progress will be presented at the conference. Amplification of the left-right asymmetry by stimulated emission of radiation while the probe beam propagates through the excited vapor takes advantage of the large number of atoms excited along the pump-beam path. In the longitudinal El-field configuration currently exploited, this number is limited only by the total voltage sustainable by the Cs vapor. In order to overcome this limit, we consider, both theoretically and experimentally, the possibility of performing the measurements in transverse E-field pump-probe configuration, requiring a much lower voltage. We discuss the necessarily different nature of the observable and the magnetoelectric optical effects of a novel kind that occur. They condition modifications of the experimental configuration with, in particular, the application of a transverse magnetic field. We suggest a means of rotating the transverse direction of the fields so as to suppress systematic effects. With a long interaction length (typically 40cm), a precision reaching 0.1% in a quantum noise limited measurement can be expected, in this case limited only by the necessity of operating below the threshold of spontaneous superradiant emission of the excited medium. By approaching this limit, however, we could greatly amplify the asymmetry using triggered superradiance.


Based on the literature, recurrent disease is observed in 4–20% of the patients receiving a kidney transplant and will lead to graft failure in 2–5% [1–6]. In a large study of the University of WisconsinuUSA that evaluated 1557 patients, followed for a mean of 7.3 years after transplantation, recurrence of the underlying disease was observed in 98 cases, i.e. 8% [7]. More than 75% of these cases were recurrent glomerulonephritides (GN) and the present discussion will therefore be limited to these disease entities. However, before going into detail, it should be realized that the above data need to be treated with great caution for a number of reasons.

Following a long period during which scholarly attention was paid predominantly to the role of change agents in organizational change, change recipients and their experiences have finally begun to take center stage. Yet the typical view of recipients has been as passive reactors to change. In this article we take steps toward highlighting the central, active roles change recipients play in organizational change events. We discuss and distinguish between dimensions of valence and activation and introduce a circumplex of recipients' affective and behavioral responses to change events. We describe the primary and secondary appraisal processes through which each response type emerges and discuss outcomes of each response type. We use our model to explain how change context and process variables affect recipients' responses to change. Finally, we discuss implications of our model for theory, research, and practice.


Understanding knowledge work and supporting it with information systems (ISs) are challenging tasks. Knowledge work has changed substantially recently and studies on how knowledge work is currently performed are scarce. Ethnography is the most suitable qualitative research method for studying knowledge work, yet too time-consuming, costly and unfocused for the fast changing IS domain. Moreover, results from qualitative studies need to be transformed into artefacts useful for IS requirements engineering and design. This paper proposes a procedure for collaborative ethnography to study knowledge work practices and inform IS requirements gathering and design illustrated with the case of a collaborative ethnographic study of seven organisations in four European countries performed in a large-scale international IS research and development project. The paper also critically discusses the procedure's applicability and limitations.

The invention relates to a construction method for a reinforced ecological floating bed. The method comprises the following steps: preparing a rectangular frame structure by connecting PVC pipes with elbows and then laying a double-layer nylon net with 2-to-4-cm meshes on the frame structure; and putting a stereo elastic filling material into domestic sewage for intermittent natural biofilm formation, hanging 30 to 50 strings of formed biofilms below the frame structure per square meter and planting 20 to 30 plants having a good purifying effect on phosphorus in the meshes of the nylon net per square meter so as to obtain the reinforced ecological floating bed. Compared with the prior art, the invention has the following advantages: the purpose of water purification can be achieved through synergism of the plants and the biofilms, the aquatic plant canna with strong phosphorus removal capability can be used, the biofilms on the elastic filling material can effectively remove nitrogen in a water body through nitration and denitrification effects, and the reinforced ecological floating bed can be widely applied to ecological restoration of a natural water body.


The average output power of fiber lasers have been scaled deep into the kW regime within the recent years. However a further scaling is limited due to nonlinear effects like stimulated Raman scattering (SRS). Using the special characteristics of femtosecond laser pulse written transmission fiber gratings, it is possible to realize a notch filter that mitigates efficiently this negative effect by coupling the Raman wavelength from the core into the cladding of the fiber. To the best of our knowledge, we realized for the first time highly efficient gratings in large mode area (LMA) fibers with cladding diameters up to 400 μm. The resonances show strong attenuation at design wavelength and simultaneously low out of band losses. A high power fiber amplifier with an implemented passive fiber grating is shown and its performance is carefully investigated.


The purpose of the essay is to give a picture of the contents and character of The Vehicle Programme at Tanum's upper secondary school. Do the students, who have graduated, understand that they have got a vocationally-oriented training? The other questions the essay will try to answer are: What different kinds of knowledge does The Vehicle Programme at Tanum's upper secondary school offer its students? Is it possible to find all the different kinds of knowledge which are mentioned in Arfwedsson and Arfwedsson's book Didaktik for larare and what is the essence of The Vehicle Programme? The essay will, moreover, try to compare Tanum's upper secondary school's Vehicle Programme with traditional Vehicle Programmes.


Technology has an established pedigree in helping to foster bonds between people over large distances. Most solutions provide some kind of medium for communication but do not adequately support the challenging task of getting people who don(cid:146)t know each other to interact in the first place. This paper suggests that an exertion interface , which requires intense physical effort from the participants, will create a better social bonding experience than traditional computer interfaces. To test this assertion, we created a system in which two remotely-located participants can play a soccer-like sports game against each other. The results generated will inform the creation of future interfaces that encourage bonding between remote individuals.


Chinese herbal medicine Curcuma longa is used in food, Chinese herbal medicine and parts of medicine. In particular, Curcuma longais also used as spice due to its unique fragrance, and curcumin substance, a Curcuma longa substance, is known as an outstanding anti-cancer substance. Thus, it is a Chinese herbal medicine that is attracting the attention of numerous researchers. This research conducted an experiment, separating substances that are found in Curcuma longa. In particular, curcumin(CUR), activation material,and other effective substances were subjected to extraction, separation and purification to verify effective substance index by production site by leveraging a method of analysis that uses HPLC.

Towards this end, each chemical combination of separated substances are subjected to physical property, IR, ¹H-NMR, GC Mass, HPLC spectrum analysis for publication.


This work presents an analysis of the dative alternance of the verb senden from German language. The theoretical assumptions from the Construction Grammar postulated by GOLDBERG (1995) regarding the ditransitive and its prepositional paraphrase and a verb-sensitive approach to the dative alternation by RAPPAPORT HOVAVAND LEVIN (2008) are compared and used as a corpus analysis tool. By means of them, it is analysed whether the constructions constituted by the verb senden and the prepositional syntagma denote an event schemata caused possession or event schemata caused motion. The precepts raised by Adler (2011) in her studies about the dative alternance in German are presented, assisting in the event distinction denoted by the construction. Thus, the realized research reinforces the author's reflections about the new facet of the preposition an that appears in transfer verbs – the addressee-an, supporting the argumentation about the fact that it is not the double object variant or the prepositional syntagma the responsible for the event denoted by the construction, but the arguments that constitute it. This research also proposes another kind of classification for the analysis of German language verbs that denote transfer event in clauses deprived of volitive agent: causal event as transfer (GOLDBERG 1995), in which X CAUSE Y (AFFECT) TO RECEIVE Z (EFFECT).


Ongoing professional development is a mandatory component of a nurse's license to practice. One such opportunity to engage in professional development is through clinical supervision. Clinical supervision is a formal arrangement embedded within a structure aimed at supporting staff and enhancing outcomes for both clinicians and service users.

Wolfram Research, Inc., 100 Trade Center Drive Champaign, IL 61820-7237 Phone: 1-217-398-070 Price: Free website http://www.wolframalpha.com/ (Note: See the Winter 2010 issue for another review of this software.) One of the more enjoyable "additional duties" that I have at the University of Nebraska at Omaha is to help other faculty and staff find new technology-based resources to support instruction in their classes. While scanning the web for new applications that might be useful, I came across various references and announcements suggesting that Wolfram Research was launching a new type of search engine called "Wolfram Alpha: A New Computational Knowledge Engine". Further investigation showed Wolfram Alpha to be an innovative and impressive new resource that was of particular interest to my mathematics and computer science colleagues. It is accessible freely on the web, and appears to work quickly and efficiently with any common browser. Wolfram Alpha was developed by Wolfram Research not only to search for answers but also to involve embedded calculations in order to bring up the most relevant data, as well data-related charts and visuals of a searched query, unlike browsers that simply generate a list of web pages that a user would have to sift through to find an answer. The website, developed in March 2009, went public with its first version on May 15, 2009. Wolfram describes Alpha as a very long-term project, similar to the Mathematica software package upon which the project is based, which has been in development for more than 20 years now. Although relatively intuitive to use and using common text for queries, Wolfram Alpha also includes a wide range of directions, tutorials, and help screens. For example, in the middle of the Wolfram Alpha home page, a video tutorial and short summary describe what the site can do and what it has to offer. Initial search suggestions for trying out the site are also included. Initially, I used short words and phrases to try out the search mechanism. For example, "corn nutrition" provided a wide variety of nutritional values for corn; and "corn prices" gave me the current pricing of a bushel of corn. "What is the population of Nebraska?" yielded 1 .783 million people. Various suggestions given regarding search capabilities to try were impressive to see in action. These include such options as searching for a date in history, which will show the most important events that occurred on that date, or entering the name of a town, which will bring up information about the town's population, geographic location, elevation, etc. A search on stock values allows you not only to check the current price of a particular stock in the market but also to compare two stocks from rival companies. The example given on this website is Apple vs. IBM. In a twocolumn comparison, the results showed quite a bit of information related to these two stocks and how they have performed in the past. In fact, all the data returned by Wolfram Alpha comes back in a well-organized and userfriendly table format. …


This article describes a pulsed thermal Time-of-Flight (TTOF) flow sensor system as two subsystems i.e., a pulsed-wire system and a heat flow system. The entire flow sensor is regarded system-theoretically as a linear time-invariant (LTI) system and is described by its transfer function or impulse response. The characterization of the thermo-fluid dynamic signals obtained by a pulsed-wire and by a heat flow is strived. Hence, the impulse response of both pulsed-wire and heat flow is analyzed according to the flow velocity. Experimental and theoretical results are compared in a flow velocity range in air between 0.1 m/s and 1.4 m/s.


Residual chlorine is a common by-product of warm drainage in coastal nuclear power plants. when accumulating to some limit, it may threaten marine ecosystem especially for benthic clam. However, there are few studies on the molecular mechanisms related to immunity and antioxidant of residual chlorine stress on clams. In this study, the clam (Cyclina sinensis) was exposed for 96 h at different concentrations (0, 50, 100, 150, 200, 250, 300, 350, 400, 450 and 500 mg/L) of residual chlorine to observe its mortality, measure the activity of antioxidant and immune-related enzymes, and analyses the gene expression level in the hepatopancreas by using the transcriptome sequencing. The results showed that the mortality rate increased with the increase of stress time and concentration, and the mortality rate in the 400, 450 and 500 mg/L groups reached 100% at 96 h. The tolerance to residual chlorine of C. sinensis decreased with the increase of chlorine dioxide concentration, and the LC50 of 96 h was 217.6 mg/L by linear regression method. After residual chlorine stress, the activity of antioxidant-related enzymes (T-AOC and SOD) in the hepatopancreas showed a trend of first increase and then decrease with the extension of stress time. The immune-related enzyme activities of AKP and LZM showed a downward trend between 0 and 96 h, while the ACP enzyme activity showed a trend of first rising and then decreasing. Transcriptome analysis showed that residual chlorine stress significantly changed the expression levels of immune-related molecules associated with signal transduction, prophenoloxidase cascade, cell apoptosis and pattern recognition protein/receptor. Moreover, glutathione S-transferase (GST), heat shock protein (HSP) and other antioxidant-related genes were significantly affected under residual chlorine stress. This study provided valuable information for understanding the effects of residual chlorine stress on survival, physiological metabolism and molecular mechanisms of immune and antioxidant functions of C. sinensis.


Benchmarks have always been one of the greatest assets in evaluating a Data Management System (DBMS) performance and providing a standard way to compare different DBMSs from various angles. As DBMSs evolve over time, new benchmarks are created, and the older ones need to advance and adapt in order to continue to be a valid and capable comparison tool. Many of the standard benchmarks use synthetic data and as such may not be able to capture the complexity of real data and its relationships correctly. The Wisconsin Benchmark was one of the first and main benchmarking tools made four decades ago by Dewitt et al at the University of Wisconsin. One of the most powerful features of this benchmark is that its relations are designed so their structure and distribution of attributes is easy to understand and control. While the Wisconsin Benchmark was a very powerful and widely-used benchmark years ago, it is given less attention in current studies. We believe that the Wisconsin Benchmark and its carefully designed relations can be utilized and provide capabilities that are unique and useful.. In this paper, we present a flexible, easy-to-use and scalable JSON Data Generator implemented in java based on the Wisconsin Benchmark Data Generator description, with more advanced features to provide relations and attributes closer to real-world data. Attribute skewness and variable length records using different size distributions are some of these newly added features. It is a ready-to-use, parameterized, and scalable data generator tool that since its development has been used in several AsterixDB's [4] performance benchmarking and publications [13,14,17,18], and we believe that can be useful to many others. The source code and more information are provided at [1].


My internet provider, like most, carries advertisements on its home page. A recent one for a dating agency invited me to enter my age, postcode and relationship preferences into a menu. For fun, I entered my details as a 95-year-old woman living in the Outer Hebrides, seeking love with an older woman. The site immediately informed me there were several suitable contacts obtainable—on payment of a fee. A similar ad the next day, for a genealogy agency, offered to trace all my relatives around the world. In the spirit of the previous exercise I entered the name Flora McFinkelstein into the menu and was instantly offered the contact details of 1963 people sharing the same surname, also for a fee. I wondered if the clan McFinkelstein might be holding a gay and lesbian diamond anniversary reunion on North Uist.

Scams like this are easy enough to see through unless you are terminally gullible, but there is a similar form of internet deception that is being targeted at doctors and academics and is harder to recognise. 'Spamnals' are online journals that approach professionals via mass email, inviting them to submit papers for publication on what seem like very favourable terms. This includes rapid processing, swift acceptance of papers and immediate publication …


Objective
To detect the genomic copy number variations(CNVs) of mice embryonic neural tissue with neural tube defects(NTDs) induced by methotrexate(MTX), and investigate the molecular genetic mechanisms between folic acid metabolism disorders and NTDs pathogenesis.

Methods
C57BL/6J NTD mice model was induced by MTX on gestational day 7.5, and the maternal serum and NTD embryonic neural tissues were collected; the array-comparative genomic hybridization(array-CGH) assay was utilized to analyze the whole genomic CNVs in NTD embryonic neural tissues; reverse transcription polymerase chain reaction(RT-PCR) was used to confirm the positive results; the maternal serum concentrations of folic acid and related metabolites and dihydrofolate reductase(DHFR) activity were detected by liquid chromatography-tandem mass spectrometry and enzymatic methods, respectively.

Results
Array-CGH and RT-PCR results showed the 3 high confidence CNVs on XqE3, XqA1.1-qA2 and XqA1.1 in the NTD embryonic neural tissues.The NTD maternal serum concentrations of 5-methyltetrahydrofolate, 5-formyltetrahydrofolic acid, S-adenosyl methionine and DHFR activity were reduced significantly compared with the control group, and there were statistical differences(all P<0.05).

Conclusions
There are obvious CNVs in embryonic neural tissue of NTD mice induced by MTX and folic acid dysmetabolism might cause mice embryonic neural tube developmental disorders through CNVs.

EPR spectroscopy has been used to study the motions of several spin-labelled and spin-trapped proteins (α-chymotrypsin, cytochrome c and myoglobin) enclosed within reverse micelles formed by sodium bis-(2-ethylhexyl) sulfosuccinate (AOT) in isooctane. In several cases the spectra obtained from the encapsulated protein are significantly different from those observed in bulk solution. The motions of the labelled proteins, inferred from the anisotropy of the EPR spectra (A‖ values), vary with the amount of solubilized water (W0) and hence the physical size of the water-pool in the reverse micelles; it is suggested that the level of solvation and the solvent structure in the water-pool of the reverse micelle cause the observed changes in motion. These results support the previously postulated 'water-shell' model of proteins contained in reverse micelles.

Telecytology has been used for education, training, and consultation. Cytological studies from gynecological, nongynecological and fine‐needle aspiration cytology (FNAC) specimens (including studies of thyroid FNAC) analyzed the diagnostic accuracy and reproducibility of telecytology‐based predominantly on static digital images. The aim of this study was to evaluate the diagnostic reproducibility of virtual cytology by measuring intraobserver and interobserver agreements among two cytopathologists, using the Bethesda System for Reporting Thyroid Cytopathology (BSRTC) nomenclature. 502 glass slides from 222 cases of thyroid FNAC were retrieved and scanned by a high‐resolution scanner generating whole slides images (virtual cytology). Conventional and virtual cytology were analyzed by a skilled cytopathologist and the intraobserver agreement rate was 77.5% with the corresponding κ value of 0.54, suggesting a moderate agreement between both methods. A second cytopathologist analyzed the same slides only by virtual cytology and the interobserver agreement rate was 80.2% with the corresponding κ value of 0.57, suggesting a moderate agreement between both cytopathologists. The virtual cytology resulted in a higher proportion of aspirates classified as nondiagnostic (20.3 and 14.9% for the first and second cytopathologist, respectively) as compared to conventional cytology (8.1%). Regarding specific diagnostic categories as defined by the BSRTC nomenclature, the follicular lesion of undetermined significance category presented the lowest concordance rates, corresponding to 5.9% intraobserver agreement and no (0.0%) interobserver agreement. We suggest that virtual cytology can be an alternative to conventional cytology in assessment of thyroid FNAC specimens, but nondiagnostic aspirates obtained by virtual cytology should be reassessed by conventional cytology.

The biological control of wireworm (Agriotes spp.) in potato crops has not yet caught up to conventional controls at a time in which deregistration of pesticides is increasing, leaving a paucity of options for growers. Some measure of control has been achieved with use of entomopathogenic fungi (EPF), and to a lesser extent, entomopathogenic nematodes (EPN), with varying success. Factors affecting efficacy range from instability of pathogens within a soil matrix to difficulty in accurately targeting a subterranean pest in a heterogeneous population. The overall aim of this project was to identify areas for improvement for biological control strategies for wireworm, through identification of bioactive compounds and exploring synergies between these and existing entomopathogens. Using historical research to identify botanical extracts for bioactivity against invertebrate pests, tea tree (Melaleuca alternifolia) and rosemary (Salvia rosemarinus) oils were found to elicit repellent properties in wireworm, positively associated with mortality. Cedarwood (Cedrus atlantica) oil produced the opposite effect, an attractant response with no adverse effects on larval health. The second aspect of the project posited a novel behavioural assay methodology, demonstrating wireworm plant preferences and complex behavioural responses to introduced botanical semiochemicals beyond that of a simple attraction or repulsion. Identified botanicals were then evaluated for compatibility with strains of Metarhizium brunneum, with each of the three exhibiting fungicidal and fungistatic effects on the EPF, but at lower concentrations improving mortality and rate of pathogenicity. Finally, wireworm behavioural responses to EPF inoculations were exploited with two fungal volatile organic compounds (VOC), 1-octen-3-ol and 3-Octanone, found to have direct bioactivity towards wireworm and marginal synergistic effects with a known biological control in the entomopathogenic nematode, Heterorhabiditis bacteriophora. The project has clearly demonstrated methods for improvement for existing biological controls and given strong evidence for use of botanicals as crop protectant compounds in an integration pest management system for potato crops.


A sensorless vector control scheme is proposed in the presence of voltage and current measurement error caused by dead-time. To overcome the pure integrator prob- lem, we modified the stator flux observer through the injec- tion of the current observation error so that poles lie in the left half complex plane. Further, upper bounds of the ob- servation error and the speed estimation error are derived in the presenece of voltage and current measurement er- rors. Experimental results show that the proposed scheme yields fairly good dynamic and steady-state performances irrespective of an applied load torque in low speed.


The principle of the "amplified halogen bonding (XB) in a small space" is here exploited as a catalytic tool for the activation of a XB acceptor substrate in a nanoconfined environment. The inner cavity of the resorcinarene capsule has been equipped with a XB catalyst bearing an ammonium unit acting as a Trojan horse to drive the catalyst inside the capsule. In the presence of the XB catalyst 5, the capsule is able to catalyze a Michael reaction between N-methylpyrrole and methyl vinyl ketone. In the bulk medium, in the absence of the resorcinarene capsule, the XB catalyst 5 was catalytically ineffective. Quantum-mechanical investigations highlighted that the Michael reaction proceeds through the activation of the carbonyl by synergistic enhanced halogen/hydrogen bonding interactions, and takes place in an open pentameric capsule.

This paper proposes an approach to the classification of respiration states based on a neural network model by visualizing respiratory signals using a spectrogram. The analysis and processing of human biosignals are still considered some of the most crucial and fundamental research areas in both signal processing and medical applications. Recently, learning-based algorithms in signal and image processing for medical applications have shown significant improvement from both quantitative and qualitative perspectives. Human respiration is still considered an important factor for diagnosis, and it plays a key role in preventing fatal diseases in practice. This paper chiefly deals with a contactless-based approach for the acquisition of respiration data using an ultra-wideband (UWB) radar sensor because it is simple and easy for use in an experimental setup and shows high accuracy in distance estimation. This paper proposes the classification of respiratory states by using a feature visualization scheme, a spectrogram, and a neural network model. The proposed method shows competitive and promising results in the classification of respiratory states. The experimental results also show that the method provides better accuracy (precision: 0.86 and specificity: 0.90) than conventional methods that use expensive equipment for respiration measurement.


The dental microabrasion treatment is an effective and conservative procedure against enamel surface defects. The white spots appear frequently in children because inactive enamel caries, hypoplasia and fluorosis. When these spots affect anterior teeth produce an aesthetic effect. We describe two cases of enamel microabrasion of the upper incisors for both cases using 37 % H3PO4 and a mechanical technique (micromotor) in a 7 year old child with enamel hypoplasia and a 7 year old boy with inactive enamel caries. The aim of study was to compare affectivity of enamel microabrasion with 37% H3PO4 and pumice using different gadgets for this mechanical technique. After the first microabrasion session, the best result was the one using resin polishing burs and home made acrylic pads respect to the group which use rubber points, but these differences did not longer appeared in the afterward sessions.


: Strauss, the advocate of classical political philosophy, made the accusation of "nihilism" against "modern rationalism" initiated by Machiavelli and Hobbes' enlightenment rationality, and advocated returning to the virtue and wisdom of Socrates of Plato in classical Greece. Strauss' political philosophy tries to return to Plato's Socrates, guide the justice with the good of natural justice, educate the legislator to return to the state of universal political community, restore the natural state of human beings. The classical natural rights lie in that the value difference derive from the hierarchy of desire, and the hierarchy of this natural value difference is regarded as the proper good and justice, just as Plato's "justice lies in the division and performance of each". According to Strauss, the good life is consistent with human nature, that is, natural law. This is justice.

A flexible and efficient chip Infrared (IR) thermal imaging system was implemented on the product manufacturing test platform by collaboration with the burn-in/wafer test, systems, process, and failure analysis teams. A liquid cooling cell was successfully designed and tested. The imaging system was applied to investigate some wafer probe power/thermal issues for server high end products. Furthermore, we applied the method of Spatially-resolved Imaging of Microprocessor Power (SIMP) [1] to translate the thermal map into a power map. Finally, we propose a new concept of product thermal qualification as a supplement and potential alternative to the traditional thermal test vehicle (TTV) qualification.


One of the sources of freshwater is groundwater, from below the ground. However, due to excessive human consumption and population growth, groundwater depletion has been a pressing problem all over the world, and it can lead to water scarcity in the future. In elevated areas where water scarcity is rampant due to its high elevation thus resulting in seasonal low surface and groundwater flow, the use of alternative water resources must be assessed. One of the alternative water resources is fog collectors which involves the use of fog harvesting technology. This paper aims to study the application of fog catchers in Atok, Benguet, Philippines by analyzing the fog water collected from standard fog catchers for one month. To determine the suitable fog catcher materials in the area, two types of mesh materials (Raschel mesh and Polypropylene) were installed and analyzed for their water collection ability, availability in the area, and strength to withstand environmental factors. An average of 0.30036 liter/meter/day and 0.20695 liter/meter/day of water were collected from the Raschel mesh and Polypropylene mesh, respectively. The results of this study can pave the way for further development and assessment of the application of fog catchers in the Philippines as an alternative water resource in elevated areas to provide solution to water scarcity.

The research of work of the architect Milan Zlokovic (1898, Trieste - 1965, Belgrade) so far has focused mostly towards analysis of his projects which are key to the study of the modern movement in architecture in Serbia and the region. This paper, however, opens a line of inquiry which focuses on another feature of his creative disposition, which has been overlooked to some extent. It is argued that this sensibility, which characterises his early projects of the 1920s, owes much to his Mediterranean ancestry and upbringing in Italy. In his projects this feature corresponds to a certain transhistorical interpretation and transposition of cultural, artistic and tectonic principles of the Italian-Mediterranean architecture. In the architecture of the regions of Italy which were under the Austro- Hungarian rule until its break-up in WW1 and particularly in Trieste, where the architect was born and lived until he left for university studies, Central European and especially Viennese cultural influences mix with those of Italian and Mediterranean origin. The aim of this article is to examine this very feature of Zlokovic's designs in relation to historical and cultural context of Trieste architecture at the turn of the 20th century. The analysis of Zlokovic's early projects is based on study of primary sources, i. e., projects and photographic documentation from the architect's family archive, as well as on secondary sources on Trieste architecture. In a more general sense, this article on the polyvalent foundation of Belgrade modern movement aims to expand the referential and interpretative field of research of modernist discourse in which architect Zlokovic had a key role.

After attending counseling for pregnant women, they are able to express disturbing feelings and feel relieved and relaxed.


Abstract In 1995 the Philadelphia Museum of Art's Education Department embarked on an experiment to see how videoconferencing technology could benefit educational programming. Since then it has blossomed into a robust full-time program that has become an important asset to both the Education Department and the museum as a whole. This article describes the Distance Learning program from its beginnings to where it is currently, and discusses the changes, challenges, and learning experiences that the staff encountered along the way.


Relapse after initial achievement of complete remission remains a major issue in the treatment of Acute Myeloid Leukemia (AML). Emerging evidence suggest a critical role of Leukemia Stem Cells (LSCs) during AML relapse. FOXM1 is a member of the forkhead family of transcription factors. Here we report a novel role of Foxm1 as a key regulator of LSCs. MLL-rearranged AML patients have a very poor prognosis and are more resistant to traditional chemotherapy. Recently, we found that high FOXM1 expression is associated with MLL-rearranged AMLs and AMLs with a complex karyotype. We also found that loss of Foxm1 significantly reduced serial replating capacity of MLL-AF9 (MA9)-induced myeloid progenitor cells and increased apoptosis of MA9-induced leukemia stem cell (MA9-LSC)-enriched cells but not mature leukemia cells in vitro. In addition, we showed that Foxm1 loss in mice markedly delayed the initiation and progression of MLL-AF9-induced AML. Notably, Foxm1 loss reduced the number of MA9-LSCs as well as quiescence of MA9-LSCs. However, Foxm1 loss significantly increased apoptosis of LSCs but not normal HSCs in vivo. Our RNA-seq data revealed that expression of both Bcl2, a survival factor and p21Cip1, known as cyclin-dependent inhibitor 1, are significantly decreased as a consequence of Foxm1 deletion in MA9-LSCs. In addition, Foxm1 loss led to down-regulation of Itga1. Of interest, Chip-PCR revealed that Foxm1 regulates Itga1 expression by directly binding to its promoter. Collectively, these data suggest that Foxm1 is required for the maintenance of quiescence and survival of MA9-LSCs. Mechanistically, we found that loss of Foxm1 inhibited leukemogenic function of MA9-LSCs, at least partially through down-regulating the a1b1-mediated integrin pathway.
 We next demonstrated that conditional deletion of single or both alleles of Foxm1 significantly delayed the progression of MA9-induced AML after initiation of disease in mice, and that pharmacological inhibition of Foxm1 prolonged disease latency of MA9-induced AML in mice. It has been reported that MA9-induced mouse leukemia cells are resistant to chemotherapeutic drugs. Notably, our data showed that deletion of Foxm1 or loss of a single allele of Foxm1 significantly increases the sensitivity of MA9-induced leukemia cells to chemotherapeutic drugs in mice. Furthermore, we found that human AML cell lines with expression of MA9, the MA9-transduced primary human CD34+ cells as well as primary bone marrow cells from patients with MA9-induced AML, are more sensitive to FOXM1 inhibition in vitro than the control human CD34+ cells. Moreover, inhibition of FOXM1 significantly prolonged the survival of xenografted mice with MA9-tranduced human CD34+ cells as well as primary bone marrow cells from a MLL leukemia patient. Of note, we found that FOXM1 inhibition also significantly induced the apoptosis of human CD34+ LSCs in vivo in xenografted mice. Our studies strongly suggest that inhibition of FOXM1 may benefit MLL leukemia patients by eliminating LSCs, thereby reducing the frequency of relapse in these patients after treatment.

The first excavation season of a joint project of the PCMA and Department of Archaeology and Excavations, Ministry of Heritage and Culture, Oman, was carried out in the microregion of Qumayrah in the fall of 2016. A single tomb was investigated at an Umm an-Nar period burial site in the area of the village of Al-Ayn. A complete ground-plan was traced, identifying the tomb as an example of a well-known type with interior divided into four burial chambers by crosswalls. The excavated quadrant yielded commingled skeletal remains and mortuary gifts: numerous beads, a number of pottery sherds and a single complete vessel, a few metal objects and a score of stone vessel fragments.


ABSTRACT The advent of what we call, 'The Corporate Marketing Internet Revolution' necessitates a radical rethinking of marketing practice and scholarship. As such, mindful of the importance of the Internet and, in particular, the Internet of Things (IoT) phenomenon, this article formally introduces and elucidates the Internet of Total Corporate Communications (IoTCC) notion. Moreover, it particularises the nature and importance of quaternary (fourth-order) total corporate communications. To date, the total corporate communications effect of the Corporate Internet Marketing Revolution has not been accorded importance in the extant literature. As such, this article seeks to address this omission.


X-ray polychromaticity is a well-known source of artifacts in clinical CT imaging. As a polyenergetic X-ray beam passes through an object, rays with lower energy are preferentially attenuated, and thus the spectrum of the beam becomes increasingly skewed towards high-energy rays. This beam hardening phenomenon results in inconsistent projection data, and produces artifacts in images reconstructed using filtered backprojection (FBP). Methods for reducing or eliminating beam hardening artifacts can be broadly categorized into postreconstruction approaches, which attempt to eliminate artifacts from an image reconstructed using FBP, or iterative reconstruction approaches, which attempt to reconstruct an artifact free image from the projection data, by incorporating X-ray polychromaticity directly into the system model. In this paper we compare a well-known post-reconstruction approach with an iterative approach that uses a quasi-Newton minimization algorithm. The post-reconstruction approach is a two-step process consisting of a soft-tissue correction and bone correction, while our iterative approach is based on modeling energy-dependent attenuation coefficients as a sum of photoelectric and Compton scattering components. Two numerical phantom experiments are used to demonstrate that the postreconstruction approach does not compensate for artifacts caused by more than one different type of high attenuation material, while the iterative approach is able to reconstruct artifact-free images in both experiments. The presented iterative approach does not require any segmentation and can readily incorporate attenuation models other than the one used in this paper.

ABSTRACT This essay examines a set of memoranda, speeches, and other official discourse issued during the Global War on Terrorism that transformed the legal paradigm under which the enemy was defined and authorized new norms of conduct previously prohibited by law. It argues that these texts employ "deconstitutive rhetoric," defined as discursive action that undermines the existing legal status of those to whom it refers and produces a disarticulate, destitute subject by denying the individual access to the civic forums in which rhetorical agency may be exercised. The essay begins with an analysis of the use of deconstitutive rhetoric in the decision to legally re-define Afghanistan as a "failed state" in order to absolve the United States of treaty obligations with that nation. It then addresses the emergence of "unlawful enemy combatant status," a new legal category not recognized under the international laws of war. The essay concludes with a discussion the Obama administration's detention and drone strike policies, which have continued to use deconstitutive rhetoric to undermine the legal status of those captured and killed in the Global War on Terrorism.


An investigation of students' perceptions of talent in relation to mathematics showed that gender stereotyped perceptions of talent were a determining factor in their planned mathematics courses in senior high school. Furthermore perception of talent affected students' intended careers which also revealed gender imbalances in participation according to the level of mathematics required, as rated by six senior teacher educators from two universities in Sydney. The Year 10 students in Advanced and Intermediate courses were from coeducational government schools in an upper middle-class metropolitan area of Sydney. Actual performance on a standardised mathematics test was used to measure students' achievement, and perception of talent and predicted mathematics participation were ascertained through use of a questionnaire. Despite similar performance on the test, boys perceived themselves as more talented than girls, and also planned to participate in the higher levels of mathematics more than girls, both in the Higher School Certificate and their intended career.


The UN Security Council (UNSC) was an important arena of confrontation between the major powers during the recent pre-war crisis on Iraq, yet the realist-materialist focus of IR theory does not provide a useful perspective for analysing the debate and the ensuing defeat of American interests. This paper seeks to establish the meaning of "power" within a rhetorical context, applying insights from Searle's theory of institutional facts, constructivism, and self-presentation theory. Rhetorical strategies are then examined empirically by means of thematic and structural analyses of key texts from the UNSC debate on Iraq.


In this thesis we adopt an artificial intelligence approach in investigating the online information retrieval activity and in studying the design of online information retrieval systems. Our initial approach was to investigate the interactions between the searcher and the retrieval system, and the searcher and the reference librarian. Our objective was to develop cognitive models of these processes that will provide a sound basis for incorporating search assistance into an online system.
This research consisted of three stages: an empirical investigation stage, a system building stage, and a system testing stage. During the empirical investigation stage, we conducted two cognitive psychology based empirical studies observing the searcher/librarian and the searcher/system interactions. We have derived some important findings from these studies. Firstly, we have identified a taxonomy of misconceptions users have about the subject area, the system and the classification scheme. Secondly, we have developed five online search strategies. Thirdly, we have developed an empirically based process model for assisting searchers in refining their queries.
At the system building stage, a blackboard architecture was adopted for our prototype system where the proposed capabilities (alleviating searcher's misconceptions, selecting appropriate search strategies, and refining searchers' queries) were incorporated. This system was created using Lisp and Flavors.
After the prototype system development effort, a system testing stage followed. Our system was tested against an existing online catalog in a laboratory experiment. The test results showed that our system out-performed the existing online catalog in search recall and satisfaction level.
Our research suggests a knowledge-based information retrieval system design. Armed with the appropriate search heuristics, the knowledge about the subject area and the classification scheme, and the query refinement mechanisms, we believe, information retrieval systems can become more responsive and intelligent, capable of providing interactive support of a variety of users.


Rhabdomyosarcomas are the most common sarcomas of childhood, comprising 5% to 15% of all childhood solid tumors and 4% to 8% of total childhood malignancies. Although primary lesions are most common in the head and neck, approximately 20% involve the genitourinary system. Most rhabdomyosarcomas present by age 10 years, and 2 age peaks are observed at ages 2 to 6 years and 15 to 19 years. However, neonatal rhabdomyosarcomas are extremely rare. Of 3,217 patients in Intergroup Rhabdomyosarcoma Study (IRS) groups I to IV only 14 (0.4%) were younger than 30 days at diagnosis.1 To our knowledge only 2 other cases of bladder rhabdomyosarcoma neonates have been reported.1, 2 CASE REPORT

We developed an on‐chip DNA analysis method, in which free‐solution transient isotachophoresis (FstITP) were coupled with CGE. Using chloride ions in the sample matrix and HEPES in the background electrolyte, respectively, as the leading and terminating ions, dsDNAs were isotachophoretically preconcentrated in free‐solution and then separated in sieving polymer. The coupling of FstITP and CGE enabled higher separation efficiency due to higher preconcentration rate in free‐solution. The FstITP‐CGE analysis offered adjustable signal intensities by varying sample injection time. With the maximum sample loading volume, the LOD of the FstITP‐CGE analysis was determined to be 0.24 ng/mL by confocal laser‐induced fluorescence detection. The FstITP‐CGE method is simple, robust and flexible, thus well suited to the analysis of highly saline DNA samples at different concentration level.


Dec 0 Tumour lysis syndrome (TLS) is an important metabolic disorder frequently encountered in the management of a variety of cancers including lymphoma, leukemia, neuroblastoma and small cell lung cancer. The acute tumour lysis syndrome (ATLS) may be a dramatic complication of anticancer therapy. It occurs mostly in haematological malignancies and less commonly in solid tumours. Spontaneous tumour lysis syndrome (STLS) has been reported more frequently in Burkitt s lymphomas than in other haematological tumours and exceptionally in solid tumours like small-cell lung carcinoma and germ-cell tumours . Delayed recognition can result in biochemical abnormalities resulting in lifethreatening complications such as renal failure, arrhythmias and seizures. Identification of high-risk patients and early recognition of the syndrome is crucial in early institution of appropriate prophylaxis and treatment.


Among various multiferroics, bismuth iron oxide (BFO, BiFeO3) is currently known as the only material that exhibit ferromagnetic and ferroelectric behavior at room temperature. As compared to the bulk, low dimensional BFO exhibits extra ordinary different properties. Such advanced properties arise because of the enhancement of surface area along with the development of energy states. On the other hand, high value of leakage current and week ferromagnetism are the two limitations that still need to be addressed. In the present study, BFO nanoparticles are synthesized using low cost sol-gel method. Chemically synthesized nanoparticles are calcined at 300 ̊C, 400 oC, 500 oC and 600 oC. X-ray diffraction (XRD) results show amorphous nature for nanoparticles calcined at 300 oC. Transition from amorphous to crystalline phase pure BiFeO3 is observed at calcination temperature of 400 ̊C. Nanoparticles calcined at temperature of 500 oC and 600 oC result in Bi2Fe4O9 and BiFeO3 mixed phases. Nanoparticles with calcination temperature of 300 oC, 500 oC and 600 oC result in weak magnetic behavior. Strong ferromagnetic behavior with saturation magnetization of 0.027emu is obtained at calcination temperature of 400 oC.


In this reply, I address four general issues raised in the commentaries. Specifically, I attempt to (a) clarify the nature of immediate-return needs, (b) provide more detail on the mechanisms through which frustration of immediate-return needs makes one susceptible to the effects of social motives, (c) address in more detail the relation between I–D compensation theory and other theoretical conceptualizations, and (d) indicate the extent to which my distinction between immediateand delayed-returned societies was accurate. I begin, however, by briefly describing the development of I–D compensation theory. In doing so, I hope to make the theory, as well as its connection to the associated literature (e.g., hunter–gatherers), clearer.


According to a 2013 report by the American Society of Civil Engineers (ASCE), almost 11% of bridge structures in the U.S. are structurally deficient. This makes durability of existing concrete infrastructures a huge concern in North America. It also brings attention to the lack of reliable quality control tools and procedures that can affect the durability of future construction. The Concrete Industry's Resistance to Change


We use the Hamiltonian formulation of the geodesic equation in the Schwarzschild space-time so as to get the variational equation as the counterpart of the Jacobi equation in this approach. In this context we are able to apply the Morales-Ramis theorem to link the integrability of the geodesic equation to the integrability, in the sense of differential Galois theory, of the variational equation. This link is strong enough to hold even on geodesics for which the usual conserved quantities fail to be independent, as is the case of circular geodesics. We show explicitly the particular cases of some null geodesics and their variational equations.


The adsorption of carbon monoxide on alumina has been studied by infrared spectroscopy. Only one absorption band can be assigned to carbon monoxide; all others are assigned to adsorbed carbon dioxide produced mainly by oxidation of carbon monoxide. The formation of carbon dioxide adsorbed on alumina is attributed to the presence of oxidising centres. These can be removed by treatment with hydrogen.


Scientific theories are developed in response to a certain set of phenomena and subsequently evaluated, at least partially, in terms of the quality of fit between those same theories and appropriately distinctive phenomena. To differentiate between these two stages it is popular to describe the former as involving the accommodation of data and the latter as involving the prediction of data. Predictivism is the view that, ceteris paribus, correctly predicting data confers greater confirmation than successfully accommodating data. In this paper, I take issue with a variety of predictivist theses, argue that their role for issues of confirmation is extremely limited, and attempt to account for the appeal that predictivism has enjoyed.


Thomas Bishop Advisor: Paul Wiegand 4/19/94 This project examines the effect of black liquor carryover from the brownstock washing section on the bleach plant effluent qualities of COD. Black liquor carryover not only directly effects the organic loading to the effluent treatment plant but also interferes with bleaching chemicals during the bleaching sequence. The goal of the project was to establish the relationship and quantify the effects of this carryover on the bleaching effluent COD. Samples of pulp were spiked with black liquor and then bleached by a D-E bleaching sequence to a specific target Kappa number. The effluents from both of the bleaching stages were analyzed for the organic wasteload in terms of COD. The effect of the carryover on the COD of the chlorine dioxide stage effluent is increasingly more significant as increasing amounts of carryover are used. The carryover cannot be shown to have any effect on the COD of the extraction stage of the bleaching process. This Is a direct reversal of the carryover effects when using a typical chlorination first stage bleaching, where most of the effluent COD is from the extraction stage of the bleaching process. The information from this project can be utilized to determine if improved washing efficiency will eliminate the need for additional wastewater treatment to meet the proposed Federal regulations. Introduction: This project examines the effects of black liquor carryover from the brownstock washers on bleach plant effluent COD (Chemical Oxygen Demand). Bleach plant effluents are one of the major contributors to the oxygen demand of a pulp mill waste stream, typically over 50% of the BOD in combined mill effluent originates in the bleach plant.(1) Several factors influence the characteristics of this effluent stream, including the chemical charge on the pulp, the organic loading in the first bleaching stages, ending pH, the change in the Kappa Number of the pulp, as well as the bleaching sequence.( 1) Brownstock Washing: The objective of brownstock washing is to remove all but the bound constituents of the liquor on the pulp with a minimal amount of dilution. Several factors effect the efficiency of the brownstock washing stage including; quality of wash water, displacement ratio, nature of the pulp, air entrainment, temperature, as well as physical parameters of the washer unit.(2) Some of the more common problems associated with the washer unit include non-uniform distribution of pulp across the drum, shower distribution profile, and an even consistency profile across the drum.(3) Some of the recent improvements in washer design have included a compaction zone, pressurized drum enclosure instead of vacuum drums, and pond washing.(4) Past procedures often compensated for inadequate washing of the pulp by the addition of sulfuric acid, to neutralize the pulp and overcome the effect of alum precipitation oflignosulfates from the acid soluble portion of the liquor carried over, but this practice has been shown to drastically decrease burst strength in linerboard pulps.(5) As in any process, the time and cost constraints limit the true efficiency of the washing process before the pulp is passed on to the next stage and eventually to the bleach plant. The amount of black liquor that is carried over into the bleaching stage effects the COD of the bleach plant effluent directly by the organic content of the liquor. In addition this carryover also interferes with the efficiency of the bleaching chemicals, leading to increased bleaching chemical costs. Black liquor carryover also leads to increased salt cake makeup due to the loss of the sodium ions in the carryover portion of the black liquor. A portion of sodium and organic fraction of the black liquor are actually bound by adsorbtion onto the surface of the fibers. This loss represents the minimal amount of carryover that a theoretically perfect washing stage would still exhibit. Due to the required makeup, with directly identifiable costs, the inorganic or sodium portion of this carryover has been investigated thoroughly with a fair understanding of the mechanisms by which sodium is transferred. Several factors effect the desorption of sodium from the fibers including pH, pulp type, and cation concentrations as well as their ionic strength.(2) The non-bound portion of the black liquor is theoretically available for displacement or diffusion and its recovery is the objective of improved washer efficiency. While some research has found that the rate of sodium diffusion will not reach equilibrium for up to three hours, Edwards and Rydin have shown that these experiments were performed in non-continuous stirring chambers and that with continuous mixing a first order mass transfer time rate constant exists which varies between 10 to 60 seconds for low Kappa kraft pulps.(6) This information indicates that at least the inorganic components of the liquor are readily transferable in the first bleaching stages. When considering the organic fraction of the black liquor carryover, the factors which effect transfer are less studied and less understood. As with the inorganic portion of the carryover the organic components will have a bound portion that may actually be "bound" to the fiber more by lack of solubility than by the mechanism of adsorption.(2) In addition, the diffusion oflignin fragments, thought to be primarily from the second cell wall as opposed to the cell comers, will transfer preferentially with regard to the smaller lighter fragments.(2) The factors that effect this transfer of the organic fraction with regard to COD are much less understood than the mechanisms which effect the sodium transfer. This information indicates that the mechanisms by which BOD and COD are diffused from the fiber mat during the brownstock washing stage are much less understood than the processes which regulate diffusion of the sodium from this mat.during the same process. This is largely due to the fact that the organic fraction may be seen as coming from multiple sources (i.e. both lignin and cellulose) while the inorganic fraction is primarily from residual black liquor only. A 1974 NCASI laboratory study established a relationship between the sodium ions of black liquor and the BOD which suggests that a linear correlation could be established between sodium and effluent oxygen demand qualities (2). This relationship is influenced by several factors which complicate universal use including; process physical conditions such as use of additives and types of suspended solids from the pulp as well as operation parameters such as wood species, cooking variations, and the Kappa Number of the pulp.(2) Several methods have been used to reduce the amount of BOD loading into the bleach sequence. These include using pressure diffusion washers before the blow tank, extended and oxygen delignification, using the bleach plant effluent as wash liquid in brownstock washers, and improved brownstock washing.(7, 8, 9) For the purposes of this project the examination will be limited to the study of the effects of reducing the carryover of the non-bound portion of the black liquor by improving brownstock washer efficiency. EPA Regulations: The newly proposed EPA regulations as set forth in December of 1993 suggest new standards for the industry effluent streams by proposing limiting the discharges on the basis of chemical oxygen demand tests and imposing more restrictive limits on the standard BOD5 tests. By using COD as a limiting quality for the effluent stream the EPA has placed severe restrictions on the effluent stream, and for some mills this may necessitate the use of additional waste treatment to meet the proposed limits. Because both organic and inorganic carbon are consumed in the COD test, the COD will almost always show a higher oxygen demand than the BOD5, but for the same waste there does exist a linear correlation between COD and BODs. These newly proposed regulations are forcing the industry to study all the sources of pollutants and methods by which their quantities in the effluent stream may be decreased without extravagant capital investment. Bleaching: The first two stages of the bleaching sequence have been shown to produce most of the effluent BOD and color loading and therefore will be the only stages used in this project.(1,8) Typically the first stage was either a chlorine or chlorine, with partial chlorine dioxide substitution, which in small quantities acts as a chlorine radical scavenger to prevent cellulose degradation.(10) Chlorine has been shown to produce products that oxidize to highly colored quinones, this is shown to be most significant at about 100% of the chlorine demand for the pulp, decreasing if the chlorine charge is either above or below this amount.(8) Newer technologies have improved this stage by adding the chlorine in several stages to prevent excess chlorine charge at the initial contact and an insufficient chlorine charge as contact time reaches the end, this also has the increased benefit of reducing the formation of both tetrachlorinated phenolics and the dioxins TCDD and TCDF when used with pH control by caustic addition of the "C" bleaching stage.(11) The typical "C" stage of bleaching has seen modifications to a ECF (Elemental Chlorine Free) sequence, both to reduce chlorinated organic compounds and reduce viscosity losses. These new sequences require total chlorine dioxide substitution for the chlorine stage, and have been shown to decrease the BOD5 of the bleach plant efiluent.(8) Chlorine dioxide has 2.5 times the oxidative power of chlorine on lignin but is selective to the lignin fraction and does not significantly lower the viscosity of the pulp indicating that there is little cellulose degradation.

There is disconnection of teaching content between moral cultivation and legal education in the teaching practice of the course Ideological and Moral Cultivation and Basic Knowledge of Law.Therefore the part of moral cultivation and the part of legal education should be constructively integrated on different levels;that is,to ideologically implement the scientific concept of development and practice the socialist core value system,to logically establish an organic system of theories and to technically integrate concepts,knowledge and values etc.


A recent comprehensive review of empirical studies that measured the strength of selection concluded that there was little evidence for strong nonlinear selection in natural populations (Kingsolver et al. 2001). The median quadratic selection gradient identified by Kingsolver et al. (2001) was only 0.1, and gradients consistent with stabilizing or disruptive selection were found at a similar frequency and to be of similar magnitude. Stabilizing selection in particular is an important premise in many areas of evolutionary biology (Travis 1989), so this finding challenges our current understanding of how selection may operate in the wild (Conner 2001; Kingsolver et al. 2001). There is already some evidence that the strength and frequency of nonlinear selection identified in the review of Kingsolver et al. (2001) has influenced how evolutionary biologists view the potential role of stabilizing selection (Barton and Keightley 2002; Zhang et al. 2002). Kingsolver et al. (2001) suggest a number of reasons why empirical studies may not find or may underestimate nonlinear selection, including an empirical bias toward selecting experimental systems that are likely to show directional selection. In addition, nonlinear selection gradients are often able to be estimated from data sets but are not published (Kingsolver et al. 2001), probably as a consequence of the paucity of significant individual gradients and the difficulty of interpreting the overall pattern of nonlinear selection from the large number of estimated gradients. Here, we demonstrate that the strength of non-


Interest rate volatility (IRV) affects a wide base of individuals, investors, companies, and even governments. Individuals who have borrowed through adjustable-rate retail products, such as student loans and mortgages, are susceptible to greater uncertainty about the magnitude of their liabilities from one payment period to the next when short-term interest rates are volatile. For individual and institutional investors in fixed-income products like corporate bonds and mortgage-backed securities, IRV translates directly into undesirable, and sometimes devastating, portfolio volatility. Routine issuers of debt, such as financial institutions, corporations, and governmental agencies, are also forced to deal with the impact of IRV on their vital funding decisions. As with other asset classes, IRV trading resides in the domain of interest rate derivative (IRD) markets. However, unlike volatility trading in spot instruments such as equity indexes, commodities, and currency cross rates, fixed-income assets and derivatives require significantly different mathematical treatments to address added complexities such as annuities and credit risk to name a few. This chapter aims to equip the reader with a foundational understanding of the vast IRD market and the quantitative tools for measuring and managing IRV. Section 20.2 provides perspective on the immensity of over-the-counter (OTC) and listed IRD markets and gives context to how IRV affects market participants. Section 20.3 introduces notation and foundational concepts required to understand various IRD contracts and their risks. Section 20.4 surveys a portion of the large literature on IRD pricing methodologies to the extent relevant to the subject of IRV. Section 20.5 reviews existing volatility trading practices, introduces model-free option-based volatility measures for various interest rates, and covers recent developments in the standardization of IRV trading. Section 20.6 concludes. A technical appendix contains additional details aiming to make the chapter as self-contained as possible.

In the past two decades, the development of nanophotonics, particularly photonic crystals, plasmonics, metamaterials and 2D material photonics, has led to the demonstration of many new and exotic optical phenomena that greatly changed our understanding of optics and electromagnetics. Bringing such cutting-edge knowledge to optical courses for undergraduate and postgraduate students can not only help the students better understand the fundamental principles of optics but also significantly increase their study interests. We have done this in the past several years and here we show some examples ranging from metamaterials to the optical responses of graphene.


The capacity of arthropod populations to adapt to long-term climatic warming is uncertain. Here, we combine theory and extensive data on diverse arthropod taxa to show that their rate of thermal adaptation to climatic warming will be constrained in two fundamental ways. First, the rate of thermal adaptation is predicted to be limited by the rate of shift in the temperature of peak performance of four life-history traits in a specific order: juvenile development, adult fecundity, juvenile mortality, and adult mortality. Second, thermal adaptation will be constrained due to differences in the temperature of peak performance among these four traits, which are expected to persist because of trade-offs. By compiling a new global dataset of 61 diverse arthropod species, we find strong evidence that contemporary populations have indeed evolved under these constraints. Our results provide a basis for using relatively feasible trait measurements to predict the adaptive capacity of diverse arthropod populations to climatic warming.


Distributed acoustic sensing (DAS) systems using fiber optic (FO) cables are becoming commonplace in many perimeter security applications. They have the advantage of cost-effectively covering large geographic expanses without temporal or spatial gaps. Recent technology advances in commercial DAS systems have significantly improved system sensitivity and the ability to generate time-harmonic waveforms similar to microphones and geophones. These waveforms can be saved at regular channel intervals along the length of the cable. Relative to microphones and geophones, there are a number of DAS limitations, including generally lower system sensitivity, random signal fading,1 and strong longitudinal radiation pattern effects. The latter limits DAS systems for detecting seismic-acoustic waves propagating perpendicular to the cable. In this paper, we investigate the use of coiled bundles of FO cable. We show that coherently stacking channel waveforms in coils improves signal-to-noise ratio (SNR) by a root mean square (RMS) factor of 6 relative to noise in unstacked channels, and that the coils generate a more omnidirectional radiation pattern relative to straight cable segments. However, this is at the expense of decreased signal power and more complex installation methods. These developments are incremental steps in enhancing our ability to use DAS FO systems for tracking ground and air vehicles. In our test, we used a commercially available FO DAS system configured to monitor ground vehicles and low-flying aircraft. The experiment was conducted in the deep sandy soils of the New Jersey Pine Barrens.2 The two primary DAS components were a laser interrogator unit (IU) and acoustically sensitive FO cable (both manufactured by OptaSense). For redundancy, we used an additional IU from the Naval Research Laboratory. We buried 3,000 m of FO cable at an approximate 30 cm depth, collecting 2,900 channels of strain time series data. We constructed four arrays by coiling cable in discrete bundles. A single bundle could contain 16-24 m of cable wound on a 20 cm diameter jig. Across the entire emplacement, we made roughly 100 such bundles (i.e. 2/3 of the buried cable was wound into coils). As a result, the sensor covered a straight-line distance of approximately 1,000 m. This paper focuses exclusively on the FO array design and installation, as well as the processing methods and benefits of using coiled arrays. Our results indicate that these methods have significant merit for enhancing DAS air and ground vehicle detection and tracking

Campus Placements is one of the most preliminary parameters for measuring Higher Education Graduation Outcome. As such, placement strategies of every such institution remain a matter of curiosity and debate. The Government approved National Institutional Ranking Framework (NIRF) outlines a methodology to rank institutions across the country on basis of various critical parameters. Therefore, with a view to determine how the top-ranked institutions are successful in terms of placing total students and salary offered is studied and analyzed through this research for arriving at meaningful inferences and interpretations. An attempt is also made to explore the various placement strategies, industry-interaction initiatives, and interview scheduling practices of higher ranked management institutions of India as well.
