Waste and industrial by-products represent a significant
percentage of the industrial landfill. The evaluation of these products has a
dual effect: it avoids both the landfill (risk of environmental pollution) and
limits the use of natural aggregates (depletion of natural resources and
landscape fragmentation and the imbalance of the ecosystem). In recent years,
applications for industrial waste have been taken into account in the
construction of roads with a great interest in many industrialized countries
and developing countries. The use of these materials in the construction of the
road is a decision based on technical, economic and ecological criteria. In Algeria, the steel plant of El-Hadjar (Annaba), due to its
activity generates a significant industrial waste (slag) which creates a
storage problem and pollution. For industrialized countries, this product is an
abundant raw material at low cost that must be used on a large scale public
works. Our study implies the use of slag in the preparation of the subgrade and
surface course (as coated). The results of chemical, physical and mechanical
analyses of El-Hadjar slag and materials developed, compared to those of natural
aggregates, can be used as aggregate in road construction.


A study was conducted during 2009-10 to assess the toxicity of chloroform extracts of Pogostemon parviflorus (Benth.) and Polygonum hydropiper (L) against red spider mite (Oigonychus coffeae, Neitner) under laboratory condition using leaf detached method. Both the plant extracts possesed the acaricidal properties on developmental stages of red spider mite. The treatment with both plant extracts exhibited prolonged developmental period which affected the population build up of the pest in subsequent generation. The efficacy of extracts was found to be dose dependent. However, except in deutonymph the duration was found to be reduced at lower dose with Pogostemon parviflorus extracts then the normal but, the result was not significant. It is also observed that high toxicity to the mite was exhibited by Polygonum hydropiper.


The purpose of this study was to create an Interpersonal Communication (IC) program for middle school students to (a) obtain knowledge of personality traits and communication skills and (b) to assess the program effectiveness. The IC program identified the communication skills (such as listening, starting a conversation, asking for help), personality types (how they think and behave), and interpersonal conflicts (communication conflict such as yelling) among middle school students. The program helped students identify what knowledge and skills they acquired at the end of the program. The IC program increased prosocial communication for middle school adolescents and helped students discover their personality types, strengths, and values.


We present a fourth-order finite dierence method for general second-order nonlinear boundary value problem iy 00 +f (x;y;y 0 ) = 0 sub- ject to two-point boundary conditions. We use nonequidistant discretiza- tion mesh and each discretization of the dierential equation at an interior mesh point is based on just three evaluations of f: The present paper ex- tends the results given in Chawla (1978) to the case of nonequidistant mesh. Numerical examples are considered to demonstrate computation- ally the fourth order of the method.


The metabolism of amphetamines and their derivatives with substituents in the propyl side chain have been studied extensively over the past 10 years. (1, 3,4, 6, 7,8, 9,10,14, 15, 20). The possible routes for metabolism are parahydroxylation, a-C-oxidation (deamination and dealkylation) and N-oxidation. The lipid-solubility plays an important role in directing routes of the total elimination, because a high lipid-solubility results in a less renal clearance, a great volume of distribution, a longer life time in the body and consequently more extensive metabolism. Weak lipophihc properties cause a high renal excretion of the unchanged compound and subsequently low degree of metabolism, such as can be observed with the ephedrines (15, 20). In general, ring substitution results in


Microwave mutation on Acidithiobacillus ferrooxidans (At.ƒ6 bacteria) was made in this study. The results showed that the microwave mutation could produce an evident mutation in the At.ƒ6 bacteria, which could improve its bio-activity and its bioleaching properties for low-grade copper tailings. The At.ƒ6 bacteria had the best oxidation after microwave radiating 60 seconds. The oxidation rate of Fe2+ reached 100 % after 24 hours, which was at least 18 hours in advanced comparing the original bacteria. The copper leaching rate of the At.ƒ6 bacteria after mutation was improved by 20 %, which showed that the bioleaching properties of mutant bacteria were much better than that of unmutated. The XRD analysis of leached residues indicated that Cu oxidized fast and dissolved to ion state with the bacterial action in the leaching solutions. Our study shows that mutant bacteria from microwave irradiation have great potentials for copper recovery from low-grade copper tailings.


1.5D, however, so a much greater speedup relative to the 2D models than is shown here is expected in those Work This report documents the development and initial demonstration of a capability to model LWR fuel rods using a 1.5D representation. The results presented here show very good agreement between 1.5D and 2D axisymmetric models of a short LWR fuel rod. The 1.5D model runs 10x faster than the 2D model, and much greater speedups are expected for full-length rod


Seventeen years ago, Jaap Spier convened a meeting of tort law experts at the University of Tilburg, where he was teaching at the time. This 'Tilburg Group', as it was called at the beginning, initially discussed fundamental aspects of tort law with an eye to 'keeping the floodgates shut', as their first publication referred to in its subtitle.1 The Group then decided to embark upon a highly ambitious project, namely the drafting of principles governing delictual liability in Europe—the Principles of European Tort Law (PETL). The Group has since grown and continues to expand.2 It is now called the European Group on Tort Law (EGTL). One of its original members, Christian von Bar, has meanwhile left the Group and is pursuing a similar project within the framework of the Study Group on a European Civil Code (SGECC), presented by John Blackie in this special issue.3 Despite its name, the Group's members are not all from Europe. The undeniable influence of US tort law as a global driving force in the development of this body of law is reflected in the fact that eminent experts from that side of the Atlantic were part of the

The letter tells us that as a result of COVID-19 we have been forced to unlearn, that is, put everything aside what we have learned, to re-learn, to acquire information on the protection measures against this disease and to learn the use of information and communication technologies, which brings new challenges to the production process, generating new work strategies. The writing reflects that through the different industrial revolutions, people have had to unlearn in order to relearn and thus be up to the requirementstechnology, which eliminates jobs but also creates new positions for those trained and at the height of these technological changes, which has generated a significant change in theaptitudes and attitudes in each and every one of the activities carried out on a daily basis.


【Objective】 The objective of this study was to investigate the difference of nitrogen release from incorporated rice straw and nitrogen utilization of rice under different tillage patterns. 【Method】 Rice straw was incorporated into field under no-tillage and conventional tillage in the late seasons of 2006 and 2007 and nitrogen contents in incorporated straw were measured at different growth stages after incorporation. At the same time,rice straw with 15N feed was incorporated into pot under no-tillage and conventional tillage,nitrogen and 15N uptake by rice plant were measured at maturity. 【Result】 Residual nitrogen amount in incorporated straw decreased and obvious differences were observed at different stages. The nitrogen loss in incorporated straw was about 60% during the 0-40 days and about 10% during the 40-100 days. However,the residual nitrogen content increased in two tillage patterns. Nitrogen in straw was more easily released under no-tillage than conventional tillage if the straw status was not considered. Nitrogen in wet incorporated straw was more easily released under no-tillage while dry straw under conventional tillage. 【Conclusion】 Great nitrogen dry matter production efficiency (NDMPE) and grain yield were observed under conventional tillage. No tillage was beneficial to straw nitrogen release,but nitrogen uptake from incorporated straw by rice plant and nitrogen use efficiency were decreased.


President Trump's nomination of Judge Neil Gorsuch to replace the late Justice Antonin Scalia has sparked many questions about how he will affect the court's ideological balance. Will he be less conservative than Scalia, more so, or roughly the same? And, readers of Kappan may wonder, how will his appointment affect the outcomes of cases that bear upon K-12 education? For clues, we can examine a number of opinions --touching on religion, student discipline, employee speech, and special education --that he has written while serving on the 10th Circuit Court of Appeals. Religion In Green v. Haskell County Board of Commissioners, 574 F.3d 1235 (10th Cir. 2009), the 10th Circuit found the display of the Ten Commandments outside an Oklahoma county courthouse to be unconstitutional. Gorsuch, writing in dissent, criticized his colleagues' reliance on the so-called Lemon test --after the historic Lemon v. Kurtzman (1971) decision--which proposed three criteria for deciding whether a state action oversteps the Establishment Clause: What is the purpose of the action, what is its effect, and to what extent does it "entangle" the state government with a religion? "Lemon has been criticized by many members of the court and a variety of legal scholars," Gorsuch noted, arguing that its three criteria are hopelessly subjective, which "[leaves] the state of the law in establishment clause purgatory." On this, and perhaps on future cases involving religious expression within public schools, Gorsuch's reasoning appears to be quite similar to that of Scalia. He, too, saw no constitutional violation in posting the Ten Commandments on public grounds and also believed the Lemon test should be abandoned. Student discipline In A.M. v. Holmes, 830F. 3d 1123 (10th Cir. 2016), the 10th Circuit Court granted qualified immunity to a school resource officer who used handcuffs to remove a student who was being disruptive by making burping noises in class. Gorsuch dissented, noting that police should not have been involved in a minor classroom disruption. "If a 7th grader starts trading fake burps for laughs in gym class, what's a teacher to do? Order extra laps? Detention? A trip to the principal's office? Maybe. But then again, maybe that's too old school. Maybe today you call a police officer. And maybe today the officer decides that, instead of just escorting the now-compliant 13-year-old to the principal's office, an arrest would be a better idea. So out come the handcuffs and off goes the child to juvenile detention. My colleagues suggest the law permits exactly this option, and they offer 94 pages explaining why they think that's so. Respectfully, I remain unpersuaded," Gorsuch wrote. [ILLUSTRATION OMITTED] Justice Scalia's opinions consistently favored school district authority over students. Thus, Gorsuch's opinion on burping may suggest a more lenient approach to student misbehavior. Employee speech In Casey v. West Las Vegas Independent School District, 473 F.3d 1323 (10th Cir. 2007), Gorsuch wrote the opinion for a unanimous panel in a case brought by a school district superintendent who had been fired by her board. The superintendent, Casey, was concerned about possibly fraudulent enrollment data in the district's Head Start program, and she took that information to the school board president. After the board president told her to drop the issue, Casey ordered a district employee to report the information to federal officials. Separately, she went to the state attorney general about her concerns that the school board had violated the state's open meetings act. Gorsuch wrote that the school district could dismiss Casey based on the Head Start issue but not the open meetings issue. He cited Garcetti v. Ceballos, 547 U.S. 410 (2006), in which the Supreme Court held that the First Amendment protects public employees when they speak on private issues as citizens but not when they speak as public employees about issues that are part of their official duties. …


Abstract Under the management pattern of enterprises group sales, how to assign all market orders reasonably and optimally within member enterprises is one of the important aspects that enterprises group has to study. On the basis of summary of the order allocation principles of enterprises group, a multi-objective optimization model is established to rationally allocate the order, maximize the total demands of assigned orders and optimize the overall profits of enterprises group. At the same time, based on the characteristics of the problem, an algorithm flow is proposed to attain the model solution. Finally, an application example verifies this model. The feasibility and effectiveness of algorithm flow are also confirmed.


Present work investigates development of the vehicle design in the Texas Tech University EcoCAR program with industry standard vehicle development process (VDP). The three different architectures considered are fuel cell, GM two-mode hybrid and belt alternator/starter system (BAS+). The design process started from the architecture selection with the use of PSAT software. Based on results, best choice of vehicle architecture among the three considered is two-mode hybrid. With Matlab/Simulink environment vehicle model is developed. The plant model and controller model is tested with software-in-loop (SIL) and hardware-in-loop (HIL) simulations. The testing of this stage is done with NI PXI and dSPACE MicroAutoBox.


The temperature dependence of Rayleigh waves in Fe(110), measured by helium atom scattering in the range of 150 to 905 K (0.91 T c ), is shown to provide new information on surface magnetization. The magnetic shifts of the surface phonon frequencies exhibit a large anisotropy, with the [110] direction showing the expected decrease of frequency for increasing temperature, while the [001] direction shows an anomalous increase with temperature. The results are interpreted in terms of a simple model


It is easy to tell people how to be environmentally friendly. It is easy to promise what you intend to do in the future. But in my mind the number of green people declines when we talk about true round-the-clock environmentalists, those who live like they teach; we cut out the talkers and look at what people have achieved instead of what they intend to do.


We analyze the choice of the truncation lag for unit root tests as the ADF(GLS) and the M(GLS) tests proposed by Elliott et al. (1996) and Ng and Perron (2001) and extended to the context of structural change by Perron and RodrIguez (2003). We consider the models that allows for a change in slope and a change in the intercept and slope at unknown break date, respectively. Using Monte-Carlo experiments, the truncation lag selected according to several methods as the AIC, BIC, M(AIC), MBIC is analyzed. We also include and analyze the performance of the hybrid version suggested by Perron and Qu (2007) which uses OLS instead of GLS detrended data when constructing the information criteria. All these methods are compared to the sequential t-sig method based on testing for the signiOcance of coe¢ cients on additional lags in the ADF autoregression. Results show that the MGLS tests present explosive values associated with large values of the lag selected which happens more often when AIC, AIC(OLS) and t-sig are used to select the lag length. The values are so negative that imply an over rejection of the null hypothesis of a unit root. On the opposite side, lag length selected using M(AIC), M(AICOLS), M(BIC), M(BICOLS) methods lead to very small values of the M-tests implying very conservative results, that is, no rejection of the null hypothesis. These opposite power problems are not observed in the case of the ADF(GLS) test for which it is highly recommended. JEL Classification-JEL: C22, C52


Many real world optimization problems cannot be formulated readily as one involving either the minimization or the maximization of a single objective function. Under these circumstances, the concepts of dominance and Pareto-optimality are usually invoked (Deb, 2001; Das & Panigrahi, 2008). A multiobjective framework provides a formal basis to develop effective optimization algorithms, and to evaluate their performances. Nature inspired algorithms, heuristic approaches that tend to mimic various natural phenomena, have been very successful in addressing multi-objective optimization problems. These algorithms are typically population-based approaches that store a set (or population) of solutions, which are regularly updated – a feature that is significant in a multi-objective framework, as it is not easy to discern between ABStrAct

This study was carried out to determine chemical, fermentation, microbiological and sensory properties of alfalfa silages of propolis added at different levels as additive. In the study, propolis was added to alfalfa silages at 0 % (control), 0.5, 1.0 and 2.5 levels. Ensiling period continued for 75 days. There was no statistically significant difference between dry matter, crude ash, crude protein, NDF ADF contents and lactic acid bacteria count (P>0.05). pH and propionic acid content decreased with the addition of propolis to the silages (P<0.01). The content of acetic acid decreased with the 1.0% and 2.5% propolis (P<0.01). Listeria spp., ammonia nitrogen and butyric acid were not found in silages. The Fleig Score of the groups containing 0.5% and 1.0% propolis was higher than the other groups (P<0.05). Sulphite reducing anaerobes, mold and Enterobacteriacaea were found to be below the detection limit and yeast was observed in the propolis group 0.5% and in only one sample. At the end of the study, it was concluded that the addition of 1.0 % propolis could increase the quality of silages.


Two competing hypotheses on market structure and performance of firms are the traditional structure-conduct-performance (SCP) paradigm and the efficiency structure hypothesis. This paper reveals the profits made by firms in the trucking industry were because of greater efficiencies than their competitors and not because of collusive activities.


Abstract Three-dimensional explicit dynamic simulations are carried out to study the failure of hybrid bolted-bonded vertical T- and L-joints under noncontact underwater explosion shock pressure. In this modelling, adherends are fibrous laminated composites having an orthotropic behavior, while bolts and adhesive layers exhibit an isotropic behavior. It is found that hybrid vertical T- and L-joints display appreciably higher joint resistance to underwater explosion shock pressure than adhesive T- and L-joints.


Deficiencies in the existing International Nuclear Event Scale (INES)[1] have become clear in the light of comparisons between the 1986 Chernobyl and 2011 Fukushima Daiichi nuclear power plant accidents.[2–4] First, the scale is essentially a discrete qualitative ranking, not defined beyond event level 7. Second, it was designed as a public relations tool, not an objective scientific scale. Third, its most serious shortcoming is that it conflates magnitude with intensity.


Cadmium telluride thin films deposited by spray pyrolysis using aqueous solution of cadmium chloride and tellurium tetrachloride of each 0.02 M on pre-heated glass substrate at 350 0 C. From the resistivity plot two activation energy calculated 380 m eV and 360 m eV at higher temperature and lower temperature region. This indicate that shallow trapping state due to the interstial of cadmium or telluride vacancies are dominates the extrinsic conductivity near the room temperature whereas at higher temperature higher temperature deep traps are appears to be operative. Chemical composition analysis reveals that CdTe thin films have good stoichiometric, n-type semiconductor.

INTRODUCTION Bilateral cervical exploration with identification of all four parathyroid glands by an experienced surgeon is considered the gold standard for the treatment of primary hyperparathyroidism. More recently, the development of preoperative localization studies has allowed a more targeted minimally invasive surgical approach. One of the largest series reported is the video-assisted minimally invasive parathyroidectomy (VAP) described by Miccoli. Unlike a purely endoscopic approach, it does not rely on gas insufflation but is based on central access through a <2 cm incision. His six-year experience of 370 cases from a total of 520 patients with primary hyperparathyroidism has shown comparable results to conventional bilateral neck exploration. There is a scarcity of publications concerning VAP in the otolaryngology literature; as a consequence, we describe our experience since introducing this video-assisted technique into a general head and neck practice and present our initial results to date.


Current DC open short test meets the bottleneck in both test time and test efficiency and its test time is nearly 1 second which causes long test time of the whole flow leading to negative impact on the manufacture delivery.In this paper,we will introduce the dynamic open short test and VTT Terminal open short test which are improved on both test methodology and test flow,and it will solve the bottleneck we mentioned above.Based on the test data comparison on the same unit,we find that these test methodology will obviously improve the efficiency and lower the cost to the semiconductor high volume manufacture.The reduction time will arrive 40 minutes if we run the whole lot.Besides that,this dynamic methodology can also be used on other static DC test items and it will lead to more improvement on the test time and test efficiency.


A new concept of a low‐frequency (<1000‐Hz) underwater sound source has been developed and tested. The oscillation of a rigid body and a means for converting the dipole oscillation of the body to monopole radiation are used in this source. The source can be powered with electric or linear motors or hydrodynamic exciters that convert tow or flow to vibration. To prove the concept, a small version of the electric motor powered source has been built and successfully tested. To extend the bandwidth of the source, the variable resonance frequency and multiresonances of the device are discussed. A gas spring with a frequency‐dependent stiffness is employed for the multifrequency resonant source design. The source promises to be reliable, inexpensive, highly efficient, and powerful.


Impacted teeth are teeth obstructed during the eruption process; the high prevalence of impacted teeth, especially third molars, accompanied by complaints that arise, requires omentectomy. Winter's classification shows various positions of impacted third molars based on angulation. This classification is judged to be describe the relationship of the apical position of the mandibular third molar tooth to the mandibular canal more clearly. The odontectomy procedure requires an excellent preoperative approach to consider the structures around the mandibular third molar, one of which is the mandibular canal, because the canal's proximity to the third molar root can increase the risk of nerve injury during the odontectomy procedure. This study aims to determine the relationship between the third mandibular impaction Winter classification and the mandibular canal distance on panoramic radiographs. The samples of this study were 53 and were grouped according to the position of the impaction vertically, mesioangularly, horizontally, and distoangularly. The study was conducted cross-sectionally by measuring the apical distance of the mandibular third molar to the upper border of the canal on a panoramic radiograph using a manual caliper. The space obtained was statistically analyzed using the eta correlation test. The results showed that 38 and 48 impactions were found to have the most mesioangular impaction, followed by horizontal, vertical, and distoangular paping the least. The mesioangular position measured the distance from the apical third molar of the impacted mandible to the closest distance to the mandibular canal, followed by the horizontal and the longest distance in the vertical position. Statistical tests were conducted to determine the relationship between the mandibular third molars and the mandibular canal. In the test results, the calculated F value on tooth 38 (2.64) and tooth 48 (0.507) was smaller than the F table value (2.794); this indicates there is no significant relationship between the two variables. The absence of a close relationship between the mandibular third molar distance and the mandibular canal indicates the possible low risk of complications in paresthesia after the odontectomy procedure.


We investigate numerically the evolution of black hole binaries embedded within geometrically thin gas discs. We find that the binary decays at a rate which is in good agreement with analytical estimates. Scaling our results, we calculate the maximum rate of binary decay that is possible without fragmentation occurring within the surrounding gas disc. We find that decay due to gas discs can be more efficient than that due to stellar scattering for separations below a∼0.01–0.1 pc. The minimum merger time scale is shorter than the Hubble time for M<107 M⊙. This implies that gas discs could commonly attend relatively low mass black hole mergers, and that a significant population of binaries might exist at separations of a few hundredths of a pc. For more massive binaries, scattering of stars formed within a fragmenting gas disc could act as a significant additional sink of binary angular momentum.


Purpose: The present paper examines IS outsourcing success through the satisfaction achieved therewith. It simultaneously analyzes how IS outsourcing may influence IS managers' job. Design: The results obtained in a survey on this topic carried out over a twelve-year period are described. The proposal consists in a model that relates the degree of outsourcing with the satisfaction achieved therewith, in which the influence exerted by IS on the systems manager's job acts as a mediating variable. Findings: The study concludes that the way in which outsourcing affects the IS managers positively influences the satisfaction achieved with this service. Implications: Outsourcing poses a great challenge for IS managers because they must devote more time to their managerial functions, and they need more knowledge too. These greater requirements or demands will most probably make these executives feel unsatisfied with outsourcing. However, the paper shows that satisfaction increases insofar as, despite all these demands, the working post characteristics improve, and the satisfaction and autonomy of IS managers grows and, most importantly, they believe that their job has a higher added value. Originality/value: No studies had hitherto related outsourcing success and the implications of outsourcing for IS managers.


Dentists will make an outstanding contribution to fluoridation programs when they see their responsibility not only to educate but also to propagandize. Complete knowledge of the detailed scientific literature is not a prerequisite for this important community role. Many competent commissions have reviewed the voluminous data on the practical effectiveness and safety of fluoridation programs.


The invention provides an axial adjusting and controlling system of a printing plate roller of a corrugated board printer. The printing plate roller is arranged between a power side mechanical wall board and an operating side mechanism wall board. The roll shaft of the printing plate extends out of the operating side mechanism wall board to be in transmission connection with a mechanical reducing mechanism. The mechanical reducing mechanism is in transmission connection with a motor which is connected with a reversible contactor. The system is characterized in that double synchronous pulleys are arranged at the roll shaft of the printing plate. The double synchronous pulleys are respectively connected with a rotary coder and a mechanical transmission limiting system. Based on axial adjustment and electric control of current printing plate roller of the corrugated board printer unit, a mechanical axial limiting system is further arranged, so that when the axial device of the device changes out of the allowed range, the system can stop the machine under the effect of the mechanical axial limiting system to ensure the safety of the device.


I report a spectroscopic observation of Rydberg polarons in an atomic Bose gas. Polarons are created by excitation of Rydberg atoms as impurities in a strontium Bose–Einstein condensate. First experiments are described on the impact of additive noise on the ionization of Rb Rydberg atoms in microwave fields. Dynamical localization and its gradual destruction by noise are observed. The atoms surviving in Rydberg states are detected by ionization in a static electric field. First, we count the number of atoms initially laser excited to Rydberg states. The ionization signal includes atoms excited to the continuum as well as atoms which are excited to principal quantum numbers higher than ne. Instanton tunnel effect is theoretically based on pseudoparticle Instanton, known like a classical solution of kinematic equations in classical theory of fields in Eucleides Spacetime. Typically events of quantum mechanics is condition of a quantum interference. Graphene is the most favourite material model with simply hexagonal structure and simply chemical composition, it's the clear mono–layer of hexagonal polygons of carboneum with kovalent bonds and electron–electron gas. The Walter Christaller's Theory of Central Places (hexagonal settlements structure) is the most illustrative sight to express the graphene chemical bond structure in macro–dimensions. It's possibly to say that graphene has a structure of microcosmos, and Christaller's Theory of Central Places is a mirror reflex of this microcosmos to extradimensional MACROCOSMOS (STRUCTURE OF HUMAN CONURBATION, CITIES, TOWNS, VILLAGES AND THEIR CONNECTIONS LIKE A NANO–CHEMICAL KOVALENT BONDS OF CARBONEUM / GRAPHENE). In the ending part of this text, the Author dedicated attention to a mafic silicar mineral biotite with its typical hexagonal space–structure like a space–point super density of hexagonal layers of this rock–forming mineral.

In order to control laser beams precisely in a caesium atom interferometer,a laser frequency and power control system which is suitable for various demands is designed.Based on an acousto-optical modulator,the system integrates the functions of frequency shift,power stabilization and modulation.Firstly,based on the principle of the atom interferometer,the requirement of the optical part in the system is proposed.Secondly,the hardware circuit system including a phase-locked loop frequency synthesizer and the LabVIEW software control system are designed.Finally,the developed system is tested.The experimental results show that the frequency shift range of the laser beam through the acousto-optical modulator is 100 ~ 200MHz;and the power fluctuation of the laser decrease to 2% using the power stabilization system.The designed system has multi-functions,achieves the desired aims and satisfies the requirements of atom transition,matter wave interference and other processes to laser beams.In addition,the designed system could be applied to other systems which need to adjust and control laser beam precisely,such as atomic clock,atom interferometer gravity gradiometer and so on.


Abstract A cosmetic ester, cetyl oleate was synthesized using microwave irradiated system. The esterification reaction was carried using Candida antarctica lipase B in a solvent-free media. The influence of various reaction parameters was studied, and the efficiency of Fermase CALBTM10000 was compared with other enzymes. Equilibrium conversion of 97.5% was obtained within 20 min at 60 °C temperature, 1:2 oleic acid to cetyl alcohol molar ratio and 4% w/w dose of lipase. A comparative study showed that microwave irradiation is a much more efficient method than ultrasound irradiation and conventional heating. Fermase CALBTM10000 was reusable over 6 enzymatic cycles as its stability improved under microwave system. Physicochemical parameters of cetyl oleate were tested in order to analyze its suitability for further cosmetic use.


The purpose of this research was to investigate the effectiveness of music therapy on general health of post-traumatic stress disorder (P.T.S.D) veterans. The research design is semi-experimental with pretest post-test and a control group. The population also included all post-traumatic stress disorder (P.T.S.D) veterans of Isfahan in 2013. In so doing, 60 veterans with post-traumatic stress disorder (P.T.S.D) were selected through convenience sampling and assigned to two groups of control and experimental randomly (30 each). The research tool for data collection was the Goldberg General Health questionnaire (1972). Music Therapy intervention was done for 12 weeks for the experimental group and the control group did not have any intervention. Data were analyzed by ANCOVA and Mann-Whitney U analysis. The results showed that music therapy intervention had a significant effect on general health of posttraumatic stress disorder (P.T.S.D) veterans in post


One of the fundamental challenges for neuropsychological aging research is how to maintain and promote cognitive functioning in old age. Previous research revealed thatan active lifestyle, social participation, and emotional support during adulthood seem to be protective against cognitive decline in old age. However, up to now, a detailed examination of the interplay of these relations based on a broader variety of past activities and considering the individual's available social capital is missing. The present study seeks to extend the literature by investigating the interactions of family based social capital as a mediator between the build-up of cognitive reserve (via the engagement in a broad variety of past leisure activities) and old age cognitive functioning in a large sample of older adults with a wide age range. A total of 2,788 older adults (aged 65–101 years) served as the sample for the present study. A test on verbal abilities, one on processing speed and one on cognitive flexibility were applied. In addition, individuals were retrospectively interviewed regarding their family network and regarding received and given support within it, as well as regarding 18 leisure activities (carried out at age 45). Present results suggest that network size as well as the given support within the family network mediate the relation between having an active lifestyle during middle adulthood and better cognitive functioning in old age. These findings are discussed with respect to models of cognitive reserve and cognitive aging.


Simple and precise UV spectrophotometric method by area under curve [AUC]-have been developed and validated for the estimation of tenofovir disoproxil fumrate in bulk and its tablet formulation. The standard and sample solutions of tenofovir disoproxil fumrate were prepared in distilled water. Tenofovir disoproxil fumrate was estimated area under curve (AUC) method, the zero-order spectrum of tenofovir disoproxil fumrate was measured in between 255 nm to 265 nm. Beer's law was obeyed in the concentration range of 1 to 20 μg/ml with coefficient of correlation value 0.9999. These methods were tested and validated for various parameters according to ICH guidelines. The precision expressed as relative standard deviation were of 0.1560% respectively. The proposed method was successfully applied for the determination of tenofovir disoproxil fumrate in pharmaceutical formulation. Results of the analysis were validated statistically and were found to be satisfactory. The proposed method is simple, easy to apply, low-cost and require relatively inexpensive instruments.


The open reading frame gene sequences of Mud crab arginine kinase was cloned through the molecular biology technology method.The cloning of arginine kinase gene amplified with sequence analysis showed that the cloned DNA fragments had open reading frames of 1 071 bp,and predicted to encode proteins with 356 amino acid residues.The obtained gene was deposited in Genbank under accession number of GQ 851626.Sequence alignment revealed that the Mud crab arginine kinase shared 94 % of homology to Litopenaeus vannamei,and more than 90 % homology to other shellfishes,such as Carcinus maenas,Eriocheir sinensis.Mud crab arginine kinase gene was further recombined with the vector of pGEX-4T-3 and expressed in Escherichia coli BL21.The expressed protein revealed a band of about 65 ku on SDS-PAGE.Western blot analysis using anti-Mud crab AK polyclonal antibody revealed positive reaction to the GST-AK fusion protein.


Experimental data on directional and bulk solidification of hydrogen-charged samples of aluminum alloy A356 and nickel alloy Inconel 718 are discussed. The solidification structure of the porous zone is shown to be dependent on many process variables. Of these variables, hydrogen content in the melt prior to solidification, and furnace atmospheric pressure during solidification play the decisive role. Also important are the furnace atmosphere composition, the solidification velocity, and the temperature distribution of the liquid metal inside the mold.


The Permian-Middle Triassic is mainly composed of carbonate rocks in the northwestern margin of the Yangtze block. In this paper, based on the application of theories and methods of carbonate sequence stratigraphy and the analysis of seismic data, outcrop, drill core and log information, we identify in the Permian-Middle Triassic strata four depositional sequence surfaces, i.e., erosional unconformity, transgression onlap sequence unconformity, subaqueous depositional break sequence unconformity and local exposure sequence unconformity. We also divide the strata into 11 third-level sequences and 23 system tracts. By the contrast of stratigraphic sequence, the sequence stratigraphic framework is established, within which characteristics of sedimentary facies of different system tracts are analyzed. And it's concluded that platform edge reef and beach facies and platform inside beach facies are the best reservoir facies belts, and the former is mainly located in highstand systems tract of sequence I (Qixia Formation), and transgressive systems tract of sequence V (Changxing Formation) and sequence VI (Feixianguan Formation).

Reminiscence is the process whereby an individual recalls the past, previous events, people, incidents. It can also be used to connect the present with the past, an event that brings to mind a similar, former event. It is a powerful tool that can be used to extract knowledge, skills and experiences held by our seniors, allowing them to share this with others, and make them feel valued. This could be of great benefit in the workplace and in other learning environments. Since 2004, a strategic change was made in the bulletin to incorporate at least one paper from all the sections viz., Drug standardization, Drug proving, Clinical research, clinical verification, fundamental research and drug research.


The isotopic thermal diffusion factor for He, Ne, and Ar has been measured by an all‐glass ``swing separator'' with its lower tube ends at 78° and 195°K, extending the temperature range of earlier data. These new data, along with the older ones, have been interpreted in terms of the L‐J (12–6) and modified exp‐six potentials. Various equilibrium and nonequilibrium properties are calculated and compared with the experimental data. An equation has been developed which relates the thermal diffusion factor with the absolute values of the viscosity, diffusion coefficient, and their derivatives and is essentially independent of the nature of intermolecular force. The thermal diffusion values are consistent with the available experimental data of viscosity and diffusion, through the use of the proposed relation, but more accurate data on diffusion as a function of temperature are needed for a precise evaluation. Approximate calculations are given to estimate the quantum corrections for He at 78° and 195°K.


Recently, Mn content in steel scrap is increasing due to the production of high strength steel for automobile body. The increase in Mn content particularly reduces the elongation of ductile cast iron. In the near future, this increase in Mn content is expected to make the production of high ductility cast iron in the cast condition extremely difficult. This paper aims at the removal of Mn from molten cast iron. First we confirmed that Mn in molten iron can be removed by adding sodium-sulfide in laboratory tests. The reproducibility was also checked in the manufacturing process. Furthermore, as a result of a study on the influence of each factor related to Mn removal, the optimal conditions for Mn removal processing were obtained.


The issue of immigration and the discourse of the press is a recurring theme in the ACD's investigation. In this paper we study the discourse of four American newspapers about the debate that Arizona Law SB 1070 raises. Law that criminalizes the undocumented. we examined 100 texts: first of all, we study the journalistic texts (news and editorials)and after we apply the theory of the actants associate to the semantic macropropositional analysis. The synchronous cut was from April 23, 2010, date of the approval until July 29 date in which it was put into effect.We find that the debate among the participants focuses on the constitutionality or not of the measure and that it leaves out of the discussion those involved, the undocumented immigrants.

The 3D computer graphics (3D‐CG) animation using a virtual actor's speaking is very effective as an educational medium. But it takes a long time to produce a 3D‐CG animation. To reduce the cost of producing 3D‐CG educational contents and improve the capability of the education system, we have developed a new education system using Virtual Actor. It includes a 3D‐CG stage, many kinds of stage parts (3D‐CG shaped models, photographs or text panels) and Virtual Actor(s). Virtual Actor is a software robot of various shapes based on 3D‐CG and speech synthesis. Virtual Actor speaks English/Japanese by voice synthesizer with facial expressions and body actions. We have developed two kinds of education system, one is a Cyber Assistant Professor (CAP) and another is a Cyber Theater (CT). CAP has been designed for a self‐learning system, which enables interactive communication between Virtual Teacher and learner. CT has been designed for a 3D‐CG story maker, which is a new 3D‐CG media player, attractive enough to arouse the pupil's interest. We also have developed the exclusive scenario language to write a scenario of 3D‐CG animation. It is a tag‐based hypertext language like HTML. Both CAP and CT convert this scenario to real‐time interactive 3D‐CG animations, which are not rendering movies. This paper describes the system architecture of CAP and CT, details of scenario language and results of experimental lessons.


My comment on the paper by Enrico Berti is larger than the paper it should comment. It includes two sections: A) the first one refers to some aspects of Berti's paper, concerning the presence/absence of the classical notion of person in contemporary philosophical debate; B) the second one is a development on person in political realm. Its method relies on political sciences and political philosophy which are fundamental field of application of the idea of person. We have to integrate the classical notion of person into to-day socio-political dialectics. With the focus on that my comment goes behind the face to face relationships or what I would name the 'short relationships'. As social scientists we are challenged by the present Plenary Session's subject to explore both the content of concept of person and its presence/absence in contemporary social sciences, sampling the notion of person prevailing in them. The ideas of man, human nature and person we at least implicitly form, influence deeply the development of social sciences and of the related policies; and reciprocally social sciences' researches shape our concept of man.


Summary: A new type of actin rods formed in both of the nucleus and the cytoplasm are implicated in the maintenance of dormancy and viability of Dictyostelium discoideum spores. The rods are composed of hexagonally cross-linked actin tubules with 13 nm diameter, and include S-adenosyl-L-homocysteine hydrolase. In addition to actin rods, the complex of G-actin and fat droplets are formed in the spore cytoplasm. Half of the actin molecules in the spores are tyrosine-phosphorylated. The high level of the phosphorylation is required for stabilizing spores. D-glucose is a trigger molecule for the actin dephosphorylation. In the contact-sensitive plant Mimosa pudica L., actin of the main pulvinus is heavily tyrosine-phosphorylated and changes in the extent of phosphorylation correlate with the degree of bending of the plant's petioles. Also in dormant forms of the true slime mold Physarum polycephalum actin is phosphorylated. In D. discoideum , SrfA , a homologous gene to the MADS-box family, is involved in the formation of the actin rods as well as actin phosphorylation.


Foam and leaf samples from ten streams in the Western Ghat region (south-west India) were examined for aquatic hyphomycetes. A total of 47 conidial forms were distinguished, 15 of them unknown. Cluster and principal component analysis suggested that stream category (defined primarily by distance from source) was the primary factor connected with the composition of fungal communities. Data from the current and earlier studies in the same region showed a negative correlation between species number and pH of streams (r = 0.3, P = 0.18). The correlation was stronger (r = 0.4, P = 0.051), when one stream with an unusually high number of species was excluded. A resampling test suggested that fungal species richness differed among stream categories, with the highest numbers occurring in mid-altitude streams.


At present,logistics outsourcing becomes a major trend for logistics of household electrical appliance industry,and how to balance the interests and risk of the logistics outsourcing is a problem for household electrical appliance enterprises to think carefully when they choose the mode of logistics.Through analysis,this article thinks that logistics outsourcing of household elec-trical appliance enterprises is helpful to optimize the management of enterprises,reduce logistics costs and enhance their core competitiveness,but it will also bring tremendous business risk,management risk,and risk of information asymmetry and being exposed.To this end,the article offers related measures to avoid risks,such as cultivating logistics management personnel,estab-lishing logistics outsourcing performance evaluation system,establish a corporate integrity evaluation mechanisms,and establishing a public information platform,and so on.


Nature builds by 1) using local, available materials which 2) self-ordering or growing by attributes shared between material and environment; 3) repairing themselves, 4) sensing and adapting to changes in environment; 5) disintegrating, recycling back into the material sink; and 6) sometimes enhancing the shared environment. The author has invented and developed materials for all parts of the paradigm either individually or in tandem. Application of these rules in funded research projects described herein are: 1) in-situ adaptive ports in ocean made from chemicals in seawater based on bio-mimicking the human body 2) self-repairing, self-sensing concrete 3) self repairing polymer composites 4) bone-mimicry material self-formation to achieve a cement/polymer composite 5) fly ash building materials sequestering heavy metals.


The article is devoted to the results of new research carried out in Tigray (Ethiopia) in October 2019. The focus is on rock-hewn churches located in the southern part of the region, in historical areas Tämben and Sähart (Endärta). These are the churches: Wuqro Yohannes Wäldä Nägwädgwad, Abunä Samu'el ʽ Abiy ʽAddi and Maryam Gunfan. They belong to different types. According to a number of features, the churches of Yohannes Wäldä Nägwädgwad and Abunä Samu'el ʽAbbiy ʽAddi seem to be one of the earliest in Tämben. Maryam Gunfan, on the contrary, is the most characteristic of the late cave-type churches for the Sähart (Endärta) area. The purpose of this article is to consider new material collected during the expedition, solving typological issues and dating of these monuments.


Changes in technology have affected a large number of sections in the domain of Ethernet. Cloud computing has provided a new dimension for virtual networks (VLAN) as well. These changes have help shaped the paradigm of computer networks on the whole and continues to be the back bone of linking various datacenters. With the introduction of shortest path bridging (approved by IEEE as 802.1aq) computer networks will experience a more refined way of getting things done in a very excellent way. Distributed Denial of Service (DDoS) on the other hand has affected computer systems and networks to a large degree, although solutions have been provided to contain the situation. Attackers typically exploit well-known vulnerabilities, many of which have readily available fixes. Complicating matters are the intrusion tools that are widely available. Intruders have automated the processes for discovering vulnerable sites, compromising them, installing daemons, and concealing the intrusion. Even security-conscious sites can suffer a denial of service because attackers can control other, more vulnerable computer systems and use them against the more secure site. The use of shortest path bridging to manage DDoS attack is not only to help contain the situation but to also provide a way out and render the attacker helpless. This paper suggests ways that can be used by a victim computer to counter a DDoS attack from a possible attacker or an unintentional attack. It helps to safeguard the user against unwarranted service which might command a computer to do without necessarily being aware. The simulation was conducted on a Linux operating system using ns3 and result obtained gives a promising future to pursue further work on the use of IEEE 802.1aq Shortest Path Bridging in managing Distributed Denial of service (DDoS).


The interconnection of a long tailed pair switch and a monolithic diode-transistor coupled structure facilitates the generation of a symmetrical triangle voltage waveform having a 150-V//spl mu/s edge-speed capability and a typical 5-V amplitude. Deviations from sweep linearity, as given by sweep speed error is typically <0.3 percent for the positive-going edge of the waveform; for the negative-going edge it is <3 percent, but this figure can be reduced by using a suggested modification. The circuit essentially employs a current rerouting technique but differs from existing fast types in that the waveform stays automatically symmetrical as the magnitude of the timing capacitor charging current is varied.


Three Christian films have become popular in the Commune of Cobly of today's Republic of Benin, notably the American "Jesus Film" (1979), the American-Ivorian film "La Solution" (1994) and the Beninese video film "Yatin: Lieu de souffrance" (2002). The discussion centres on how people receive and understand these films together with the digital video technology that facilitate their recent success. Christian films are so important in this part of Benin that the question needs to be raised whether Christianity is shifting from a religion of the book towards a religion of film.
The theoretical starting point is semiotics, a theory that has been foundational not only for film, media and media reception studies, but more recently also for the study of materiality. This thesis' main theoretical contribution is a critique of semiotics, arguing that this theory, which has been foundational to Western science, is in fact too limiting. Semiotics, even in its Peircean orientation, cannot sufficiently explain how people in the Commune of Cobly understand shrines, film and media more generally, both through their material manifestations and interactively in terms of communication. Instead, a process called "presencing", which goes beyond semiotics, can explain better people's understanding of shrines and media.


The effects of gas composition,main voltage,pressure,temperature and active screen size on the voltage-current characteristics of bias in active screen plasma nitriding was studied.The voltage-current characteristics are explained by glow discharge theory.The results show that the voltage-current characteristics of the bias is linear growth in H2 or N2/H2 mixture gases.But in N2,the curve is non-linear and a knee point of the curve appears at 250V.It is also found that the current is increased with increase of the main voltage and pressure,but decreased with increase of the temperature under constant bias.No significant influence of the active screen size on the curve is observed.

The speaker, who is a priest and an architect, offers some reflections coming from his professional activity. His experience with some clients allows him to focus on some questions. The main problem is the consideration itself of architecture, which does not necessarily meet with particular interest; on the contrary, it is more and more disregarded. Even the best clients lack nerve, passion, ambition, pride, i.e. the strong feelings and the convictions which make artistic creation possible. Understanding the profound reasons for this is not easy. Theology can probably help interpret this situation and contribute to finding a solution.

Analyses for the present paper were carried out from October 2009 to February 2010. Grain seeds for microbiological analyses were sampled from various grain stores, both from granaries and from silos, in Brzeznica, Czernichow and Tomice communes in Malopolskie province, from individual farms and from agricultural schools. Quantity of microscopic fungi - Micromycetes in the stored grain seeds was influenced by the following factors: seed moisture, store type, grain type and length of storage. 10 out of 22 isolated fungi belonged to potentially toxicogenic genera: Alternaria alternata, Aspergillus candidus, Aspergillus flavus, Aspergillus fumigatus, Fusarium graminearum, Fusarium nivale, Fusarium oxysporum, Fusarium redolens, Penicillium citrinum, Trichoderma viride. Metabolites of the following strains showed the strongest phytotoxicity: Aspergillus flavus - strain isolated from spring-wheat 'Bombona' cv., Penicillium citrinum - strain isolated from spring barley 'Poldek' cv. and Fusarium graminearum - strain isolated from winter-wheat 'Tonacja' cv.


Krzysztof Kieślowski is a cult figure among Russian moviegoers, but "proving" this is not as easy as in the case of the popularity of other Polish classic names in Russia, such as Andrzej Wajda and Krzysztof Zanussi. Placing Kieślowski on the list of Polish filmmakers who have influenced Russian culture in this or some other way is a not obvious move. The article is an attempt at exposing the reader to the presence of the director's films in Russia through the history of the distribution of his films, an analysis of reviews by Russian authors and texts in which Kieślowski's name appears. It also discusses references to his films in works by other filmmakers. It is complemented by the statements of two Russian directors who talk about the importance of Kieślowski in their work and academic practice.

The variability of the optical energy distributions of magnetic CP stars are investigated using indices based on fitting pseudo-continua through those magnitudes least affected by the photometric peculiarities of these stars. Examples of variability consistent with that previously found using other colors and indices are presented. The performance of the indices is evaluated by the examination of the feature profiles as measured by spectrophotometry


Recent media reports suggest Labour MPs may be gearing up to move against Jeremy Corbyn. This is supposed to happen before a change in rules could see the number of nominations needed for any would-be candidate to enter a leadership contest reduced. Yet Corbyn was not elected by mistake, explain Tim Bale, Paul Webb and Monica Poletti. A large number of Labour members – whether they joined before or after Corbyn was nominated by MPs – wanted what they got. Persuading them to change their views now they've got it will not be easy.


Vortex tube is a non-conventional device which is capable of separating hot and cold gas stream from an inlet gas stream with proper pressure energy. Number of researches has been carried out in order to identify the parameters which affect Vortex tube performance. The performance of the vortex tube depends on types of parameters, firstly inlet air pressure of compressed air, cold mass fraction and secondly tube or geometric parameters such as length of hot side tube, cold orifice diameter, number of nozzles, diameter of nozzle, cone diffuser angle and also material of vortex tube affects Coefficient of Performance. The RHVT (Ranque Hilch Vortex tube) has been used for many appliances in different engineering applications. Because of its compact design and low maintenance requirements, it is very popular in cooling and heating processes. Despite its simple geometry, the mechanism that produces the temperature separation inside the tube is fairly complicated. There is no theory so perfect, which gives the satisfactory explanation of the vortex tube phenomenon as explained by various researchers. In this paper we have experimentally studied the pressure vs. temperature graphs and result conclusions for different valve angles of diffuser and the material used is cast iron.


Electric power marketing is faced with a number of endogenous and exogenous risks while it is in full swing. And it has become the problem to be solved urgently to accurately identify these risk factors and their influences, so as to promote the smooth development of the electric power market. In this paper, the data related to 167 enterprises operating in the electric power market in Shanghai, Guangzhou, Qingdao and other cities are adopted. And the big data dual channel marketing model is used to analyze the risk factors of the electric power marketing. Studies show that the key risks that influence the electric power marketing include the network marketing risk, the cross-border electronic payment risk, the electronic customs clearance risk, the logistics risk and the credit risk; laws and regulations can have an indirect impact on the power marketing by influencing the online transactions, the customs clearance and other means.


The traditional notion of intellectual - white, heterosexual, man - lags behind the productions of the black / afro-diasporic intellectuals of the twentieth and twenty-first century, when united to the notion of mental decolonization the gap widens, so that the intellectuality of black women is also thinking ways to decolonize knowledge and question established places, for example, within the University.


The addition reaction between melamine and formaldehyde has been kinetically separated from the subsequent condensation stage by suitable choice of concentration and temperature conditions. The reaction, which is reversible, has been monitored by estimation of the free formaldehyde content of the system. It has been investigated over the range of mean degree of methylolation 1 < R′ < 3.7 of the melamine nuclei, the temperature range 25–55°C., and the pH range 5.7–10.2. The rate data thus obtained have been treated according to the random reversible addition scheme for which reasonable, first approximation, agreement was obtained. Average kinetic and thermodynamic constants have been calculated and are discussed in terms of the present model. The factors which are likely to cause deviations from randomness are described. The addition of formaldehyde to melamine proceeds by superposition of an OH−-catalyzed step with a minor solvent-catalyzed or uncatalyzed one.


The friction-induced charging (i.e., tribocharging) and the following discharging (referred here as tribodischarging) are always believed to have negative effects on the daily life and on the industrial production. Thus, how to inhibit the tribocharging and the tribodischarging has caused wide public concern. Because the discharge caused by the electrical breakdown of the ambient gas is generally accompanied with the generation of light, we investigated here the tribocharging and the tribodischarging by observing the light emitted during friction. We found that the position reversal of the friction pair has a dramatic impact on the intensity of the tribo-induced light. Experimental results show that an intense light is produced when a stationary Al2O3 disk is sliding on a rotating SiO2 disk, but only a weak light is observed for the case of a stationary SiO2 disk and a rotating Al2O3 disk. This means that the process of the tribocharging and the tribodischarging can be significantly influenced owing to the change in the relative position of the friction couple. The experimentally measured polarities of the tribo-induced charge on the friction surfaces further indicated that the strong discharging occurs when the rotating surface is negatively charged. The reason for the difference in the intensity of the tribocharging and tribodischarging can be attributed to the combined effects of the contact potential difference and the temperature gradient between the contacting surfaces on the charge transfer when friction. Finally, a simple, low cost, yet effective approach, i.e., just keep the friction partner whose surface is tribo-induced negatively charged as the stationary one, can be utilized to suppress the intensity of the tribocharging and the tribodischarging. This work may provide potential applications in numerous areas of science and engineering and also in the everyday life.


The interest in cruise tourism having been increased dramatically in recent years, the number of cruise tourists is increasing. Our country is located in the principal geographical condition on the cruise route in Northeast Asia, so we are in the advantageous environment. The government has recognized it as a high-value marine tourism industry and has being promoted the various policies to improve the economic impact of the cruise industry. In accordance with it, overall infrastructure of the private pier , terminal and experts are also required. It is expected that a large number of new cruise terminal will be established in our country. In addition, it is required that systematic study on spatial composition and circulation for the humanistic types of terminals for the rational usage of the cruise terminal. Therefore, this study examines the characteristics of the types of cruise terminal throughout the examples of overseas. As comparing and analyzing the spatial components and circulation of the cruise terminal, considering their relevance, this study suggests that an efficient space configuration and rational circulation system.

Interleukin (IL)-12 and transforming growth factor (TGF)-beta1 regulate the balance between pro- and anti-inflammatory cytokines in animal models of malaria. Since the cytokine balance may be an important determinant of whether a protective or a pathogenic immune response develops, plasma cytokine ratios were examined in Gabonese children with various degrees of malarial severity. Severe disease was characterized by high-density parasitemia and severe anemia. IL-12 and TGF-beta1 were significantly lower, whereas tumor necrosis factor (TNF)-alpha and IL-10 were significantly higher in children with severe malaria. The ratios of TGF-beta1/IL-12 and IL-10/IL-12 were significantly higher in the severe, compared with the mild, malaria group. In contrast, ratios of TGF-beta1/TNF-alpha and IL-10/TNF-alpha were significantly lower in the severe malaria group. These results suggest that the inflammatory cascade in severe malaria is characterized by suppression of the protective effects of TGF-beta1 and IL-12, and that overproduction of TNF-alpha may promote deleterious effects, such as severe anemia.


Objective Objective To observe the effect of electroacupuncture on the gastric function of patients undergone laparoscopic surgery, by observing the changes of gastric mucosal partial pressure of CO2(PgCO2), arterial partial pressure of CO2(PaCO2), and the partial pressure difference [P(g-a)CO2] during surgery. Methods Sixty-two patients who were going to receive laparoscopic surgery were included for a randomized single-blind controlled clinical trial. They were divided into two groups: thirty-two in the control group were intervened by ordinary general anesthesia; 30 in the treatment group were given electroacupuncture in addition to general anesthesia till the end of the surgery. During the surgery, data of gastric function and arterial blood gas analysis were collected for evaluation. Results After intervention, there were significant differences in comparing PgCO2 and [P(g-a)CO2](P0.01, P0.05). The intra-group differences in comparing all indexes were statistically significant in both groups(P0.01). Conclusion Electroacupuncture adopted in laparascopic surgery with general anesthesia can guarantee the supply of blood oxygen to gastric mucosa, thus protecting the gastric function.


Aim of the study The aim of the paper is to assess changes in organization and supervision of bathing areas and sites occasionally used for bathing in Poland after the implementation of the Bathing Water Directive 2006/7/EC. Material and methods The study is based on the law regulation published in the Journal of Laws and Polish Monitor Official Journals of the Republic of Poland). Also, Chief Sanitary Inspectorate annual reports and Bathing Web Service (www.sk.gis.gov.pl) were used in the investigation. The analysis of the number of bathing waters covers the period of 2010–2019, while the quality of bathing waters was analysed in the period of 2014–2018. Results and conclusions In terms of quality, the highest number of evaluations of water unsuitability for bathing in 2011–2018 was given due to cyanobacteria blooms (the highest in 2018). The assessment of water quality carried out in 2018 (being the mean from 2015–2018), similarly to the assessment from 2014 (the mean from 2011–2014), indicated the excellent quality of more than 70% of bathing waters, about 10% were sufficient and only 3 inland bathing waters (1%) were found to have poor quality. According to data from 2018, Poland ranks 22nd among EU countries in terms of the number of bathing waters with excellent water quality. Despite the constantly growing tendency to improve the quality of bathing waters, when compared to other EU countries, Poland still lacks a lot to the European average of 85% of bathing areas with excellent water quality.

To stay in touch with reality, universities need to adapt their courses to
the needs of employers. We analyse 510 job advertisements in the area
of supply chain management in order to understand the skills that
employers are seeking from employees, the type of jobs that these will be
conducting, and the personal characteristics that are preferred by
employers. The information contained in the advertisements was captured
by means of 132 keywords. The resulting data set was analysed using
multivariate statistical tools: Ordinal Multidimensional Scaling and Cluster
analysis. It was found that every advertisement can be described by
means of six dimensions: managing versus planning; analysis versus
applicability; experience required; a focus on the firm's internal processes
versus a focus on the firm's external stakeholders; the level of expertise
required; and the way in which employers reward employees according to
the skills, duties and job type. Advertisements fell into two categories,
those aimed at experienced individuals who were enticed to change jobs,
and those aimed at graduates. Skills required from graduates included
analytical skills, and ability to solve problems. The consequences for
designing university courses in supply chain management are explored.


Abstract One of the main classifications of materials uses the categories of metals, semiconductors and insulators. However, the boundaries are vague. In so-called confined metals the mobility of conduction electrons is restricted by at least one of the following circumstances: (a) Tendency towards electronic localization in covalent bonds, on ions or in lone-pairs (chemical confinement). (b) Contrast of bonding interactions in adjacent parts of the structure, i.e. separation of metallic and non-metallic domains (structural confinement). (c) Reduced size of metallic particles (size confinement). One playground for the investigation of the properties of matter at the limit of the metallic state is the chemistry of low-valent bismuth compounds, from which metallic nanotubes and nanorods, crystalline metal/salt hybrids, low-dimensional metals and unique clusters emerge. Strange physical effects, like coexistence of ferromagnetism and superconductivity, are found.


The art of Chinese prehistoric ancient painted pottery is unique. Underneath its fullness of form and luxuriant pattern, it reflects the aesthetic consciousness of self-observation of prehistoric ancestors. Ancient painted pottery schema (图式) is a holistic visual presentation of form, pattern, structure, rhythm, and color, as well as a unity of multi-dimensional spatial perception such as vision, touch and perception. In this article, the "图" in "图式 " is based on the iconographic research method of prehistoric ancient painted pottery patterns, and the "式" takes the schematic structure of the pattern as the starting point. From the three aspects of "pattern" — drawn from the eyes, "vessel" — taken from the bodies, and "schema" — comprehended from the hearts, the author detaches and analyzes the "personification" artistic features that appear in the ancient painted pottery patterns of the Neolithic Age in China. The purpose is to use this unique aesthetic outlook to trace the origin of later aesthetic concepts and provide a three-dimensional interpreted concept for them.


Acyl coenzyme A: monoacylglycerol acyltransferase 2 (MGAT2) catalyzes the committed step of the monoacylglycerol pathway for the synthesis of triacylglycerol in the small intestine.  MGAT2 is an emerging target for the treatment of metabolic diseases such as obesity, type 2 diabetes and dyslipidemia.  Multiple pharmaceutical companies have launched medicinal chemistry programs and several MGAT2 inhibitors have been described in the patent literature.  However, due to the membrane bound nature of the enzyme and the hydrophobicity of its substrates, in vitro assay techniques used for traditional kinetic studies on soluble enzymes cannot be applied. To circumvent this obstacle, we synthesized the novel, soluble radioligand [ 3 H]-Compound A and established steady state and kinetic binding assay protocols.   In the steady state radioligand displacement assay, diverse novel chemotypes that were identified in a high-throughput screen were found to compete binding of [ 3 H]-Compound A, indicating the broad utility of [ 3 H]-Compound A for testing various classes of MGAT2 inhibitors.  In the dynamic binding assays, the kinetic values of MGAT2 inhibitors such as K D , K on , K off and the residence times of inhibitors on MGAT2 enzyme were derived. Inasmuch as pharmacodynamic effects for enzyme inhibitors are driven by the physical interaction of the enzyme and inhibitors, the current binding assays provide a unique platform for identifying MGAT2 inhibitors of longer residence time as therapeutic candidates.

467 After a cluster of cases of pneumonia was reported in the Wuhan province of China in December 2019, a new strain of Coronavirus gained global importance. It rapidly spread across various countries. Deeply concerned by its alarming levels of spread and severity, the WHO finally called it a pandemic [1]. The year to come would be dominated by this single event, as no year has been since the Second World War. Going through the euphoria of false victory due to herd immunity by the beginning of 2021, India stepped into the critical stage after the emergence of new strains [2]. With more than 20.2 million cases of COVID-19 being reported, a rolling average of 4,12,262 cases daily and death tolls crossing 3,980 per day, hospitals, and health workers were overwhelmed and exhausted across the country [1,2]. As a result, a draconian step needs to be taken. The economic fallout after the pandemic threatens a wave of defaults across the globe, where people are foreseeing the darkened sky of the gloomy evening with a picture of millions being pushed into extreme poverty and famine amidst acute scarcities. With the virus spreading to 220 countries extensively, the human toll in India after the second wave is more than double the number of humans killed over 320 natural disasters during the past two decades [1]. The COVID-19 pandemic has created the largest disruption in social, economic, political, and educational systems in history. We have now realized that medical fraternities need more workforces to embrace the enduring competencies of professionalism, thereby accounting for better skills for addressing the health challenges today [3]. Successful residency in medical careers have always implied perseverance in both theory and practical classes. One has to give extra conference presentations, do well in bedside clinics, and have meaningful non-academic extra-curricular activities as well. A combined effort of all these aspects reflects the knowledge, persistence, dedication, and collaborative spirit of a medical scholar. This trajectory has suffered a detrimental disruption owing to the suspension of curriculum in recent times. Reduction in patient interaction, which is vital for both skill acquisition and relationship building, has become a serious issue that needs urgent attention. Students are thereby losing the opportunity for personal development through case presentations and bedside examinations. Looking into the Indian scenario, the second wave of COVID-19 affected the country the most. Hospitals across the country experienced a dwindling oxygen supply and a scarcity of beds [4]. In such heartbreaking times prevalent in India, lack of manpower has compelled the government to take strict decisions regarding deployment of final year MBBS students and intern doctors to COVID-19 dedicated duties across the nation [4]. As hospitals have exploded with the growing number of COVID-19 patients across countries, most medical associations have already formulated guideEffects of the COVID-19 pandemic on post graduate gynecological training and surgical skills: Indian perspective


Oversowing Lotus uliginosus cv. 'Grasslands Maku' offers considerable scope for improvement of understorey forage production in New Zealand's plantation forests. In a grazing trial in Kaingaroa Forest annual forage yields of predominantly Maku lotus were 3000-5000 kg/ha dry matter (DM) from tree age 4-7 years but declined to 1000-3000 kg DM/ha by age 11 years. Forage yields available for grazing under different tree stockings (100,200 and400 stems/ha) were (up to treeage 11) approximately the same, in spiteof the percentage area covered with slash being significantly affected by tree stocking. Forage species composition since time of oversowing has changed from initial stands of almost pure lotus to a mixture of lotus and lower fertility grasses, particularly Yorkshire fog, and flat weeds. By tree age 11 years (8 years after oversowing) lotus comprises 20-30% of understorey ground cover, both with and without cattle grazing.


A teaching strategy is an organized and systematic procedure employed by a teacher in making students learn.  It consists of steps which are logically arranged. A teacher employs it to make the learning process a more directed undertaking and to make it highly efficient, thus maximizing the teaching output. Without it, learning becomes cumbersome and a big waste in terms of efforts, time, and even money. The teaching strategy is primarily a matter of organization of materials and effort to get certain definite things done. The organization of the content to be taught and to be learned is part of this method.  Teaching strategy in English teaching is an organized, orderly, systematic and well-planned procedure aimed at facilitating and enhancing student's learning. It is undertaken according to some rule which is usually psychological in nature. That is, it considers primary the abilities, needs and interests of the learners. It is done to achieve certain specific aims of instruction. To make it as an effective instrument, it should be presented with certain amount of efficiency and ease.

While 3 percent of the fields in Norway are grown organically in the advent of the 21st century, only a small share of the resulting products reaches the consumers as organic food. A number of factors can explain the relative lack of success of organic products through the value chain. Lack of differentiation from conventional foods may discourage consumers. Extra costs limit the interest of processors and retailers. The political decisions and subsidies are directed at production, and have few direct effects on the organization of the value chain.
The marketing of organic products has followed different strategies. Organic milk is handled through the national dairy cooperative, and around forty percent is sold as organic varieties of conventional brands. Meat producers have been less successful as only about twenty percent of the certified production is marketed as organic. In some of the more promising cases organic products are marketed in a niche strategy where organic production methods is one of several differentiating product attributes.


An RF system using solid-state switching has been designed and constructed that is capable of driving a pair of loop antennas with a circulating power of 60 MW for millisecond pulses. The primary application of this system is to produce an oscillating magnetic field in the frequency range of 0.2 to 0.7 MHz, to generate and sustain large plasma currents. The maximum power transfer from the RF source was measured to be greater than 10 MW. The driver consisted of 12 insulated gate bipolar transistor (IGBT) modules driven in parallel, and was capable of switching 20 kA at 1600 V. A sinusoidal current waveform with large circulating currents was obtained on the antenna by incorporating the antenna in both parallel LCR and series LCR resonant circuits. Other switch configurations such as the H bridge are being evaluated for a much larger driver that would deliver enough power (several hundred MW) to bring the plasma to fusion conditions.


dige Nachrichten von alten und neuen theologischen Sachen (1702-19) and lasted under various names until 1761.2 He is famous for his attack on pietism and the philosophy of Leibniz and Wolff. Although his theological interests and a varied professional career took him to Jilterbog, Delitzsch, Wittenberg, and finally Dresden, where he resided from 1707 until his death in 1749, he found time to write and to revise a handbook for students of Germanic linguistics. After the fashion of the day he included Gaulish and, so far as he knew them, the other Celtic languages, since he believed them to be Germanic languages. His booklet is probably the first conspectus of Celtic studies. His letter to his friend Christian Feustel declares his intentions in writing Literator Celta:

mize some of the distortions from the first. In addition to these two "world" maps, there are 26 regional maps. Of course, judging by today's standards, we can see that the distortions of the maps are primarily due not to the methods of projection but to the errors in position of the specific locations, especially as they get further from the Mediterranean region. In this important edition, the authors have translated only the "theoretical parts" (Books 1, 2, 7 and 8), thus eliminating the lengthy lists of places. They did this to shift attention away from topography to the theory and methodology of map-making. The book begins with a long introductory section of over 50 pages, giving the reader a grounding in fundamental geometrical information and projection techniques required for fully comprehending the maps. The book presents historical background material on the work and the history of the manuscript versions as well as the translations. Following the four translated Books of the Geography (the core of this edition) is a series of plates and maps and eight appendices. Several plates are wonderful color reproductions of the "world" maps, while many of the maps portray sections of Ptolemy's version and juxtapose these with present-day projections of the same sections—a most interesting comparison. This is an important publication for historians of science (especially of cartography) and classicists. Although the novice reader will enjoy perusing the plates and maps and certainly gain from some of the early introductory material, the rest of this edition is directed primarily to the advanced scholar.


(57) Abstract: reducing the coagulation of the fluid to be sprayed, an actuator for a fluid dispensing (100a, 100b, 100c, 100d, 100e, 100f, 100g, 100h) and dispensing container is disclosed.


Atomic layer deposition (ALD) is a special type of chemical vapor deposition (CVD) technique that can grow uniformed thin films on a substrate through alternate self-limiting surface reactions. Recently, the application of these thin film materials to catalytic systems has begun to attract much attention, and the capacity to deposit these catalytic films in a highly controlled manner continues to gain importance. In this study, IrO2 and NiO thin films (approximately 25 to 60 nm) were deposited on industrial Ni expanded mesh as an anode for alkaline water electrolysis. Different ALD operating parameters such as the total number of deposition cycles, sublimation and deposition temperatures, and precursors pulse and purge lengths were varied to determine their effects on the structure and the electrochemical performance of the thin film materials. Results from the electrochemical tests (6 M KOH, 80 °C, up to 10 kA/m2) showed the catalytic activity of the samples. Oxygen overpotential values (ηO2) were 20 to 60 mV lower than the bare Ni expanded mesh. In summary, the study has demonstrated the feasibility of using the ALD technique to deposit uniformed and electroactive thin films on industrial metallic substrates as anodes for alkaline water electrolysis.


It has become possible to implant a network of Bio sensor nodes inside human body for remote health monitoring, diagnostic and prosthetic purposes. For communication of these sensors the channel available is human tissue. The sensors communicate using wireless technology, by sending information as electromagnetic (EM) radio frequency (RF) waves. These signals encounter a significant loss during transmission because this communication channel contains a major portion of fluid. To find out this loss, a propagation loss model PMBA has already been developed. This paper investigates the appropriate distance between nodes for better communication. The frequency range of Radio spectrum (1GHz to 3.5GHz) is used for MATLAB simulation. It is observed that as frequency of transmitting signal is increased, the distance limit is decreased and Power loss is increased. Using radiation pattern it is shown that the electric field intensity decreases with increasing distance.


Photovoltaic (PV) manufacturers are providing warranties for their products. These warranties are regulated by federal and state laws; however, it appears that most PV manufacturers are unaware of the applicable laws and are therefore exposing themselves to unintended liability as well as leaving their customers somewhat uncertain about their warranty rights. The requirements of warranties for PV systems are examined, and methods for economically verifying the performance of a PV system are discussed. A model warranty for PV manufacturers is included.


Throughout most of its range the Palaearctic moth Hepialus humuli shows a striking sexual dimorphism correlated with a dimorphism in wing scale ultrastructure. Male uppersides are uniformly silvery white, due to light reflection from unpigmented scales with an elaborate internal cuticular meshwork; the conspicuous wings are visual cues for females when lekking males swarm at dusk. Female uppersides have a yellow-and-orange pigment pattern, and commonplace scale morphology. Male specimens from the Shetland and Faroe Islands populations are polymorphic, with wing uppersides ranging from the typical uniform white to being patterned much as in females, or even more melanic; forewing length is slightly greater in the darker and patterned male morphs. Male wing-scale polymorphism is only modest: even the superficially most female-like specimens are overall similar to typical males with respect to important details of scale structure. The polymorphic N. Atlantic forms are likely derived from dimorphic ancestors of the continental type. The principal selective force favouring male darkening in these insular populations is most probably a locally strong predation by visual hunters (primarily gulls and terns) on the lekking moths, combined with a lessened importance of the colour-related conspicuousness of males for female mate-searching at the high ambient light level at the swarming time at these high latitudes. This assumption is supported by the finding of a higher abundance of cryptic males (and perhaps by the smaller average size of the non-cryptic male morphs) in sites with intense bird predation.
