Abstract : Exploratory research was conducted to determine the stages and nature of degradation of glass fiber-plastic composite systems under various environmental conditions. Glass fiber-epoxy structural composites have many characteristics that are desirable in Army materiel; however, they suffer appreciable losses in strength on storage in high humidity-high temperature conditions. A number of mechanical, physical and chemical tests were performed on the individual components in the system and on samples of composites made of these components. It was found that the glass filaments are a reactive component and lose their strength rapidly on direct exposure to water at elevated temperatures. Magnesium is a particularly active component. It was also found that the silane coupling agent that is incorporated in standard commercial glass finishes is a possible reactive component. It is recommended that research be conducted to find ways to stabilize the glass and glass fiber-epoxy composite structural materials against water degradation. A possible experimental research program was outlined for this purpose. It was emphasized that the most pronounced need is to establish a formulation and application procedure for a protective finish material. This material is a critical part of the structural system and should not be left as a proprietary, unregulated part of the system.


Plates were injection molded from isotactic polypropylene filled with up to 40 wt% Mg(OH)2 and investigated by site-resolved wide-angle X-ray scattering measurements, performed directly on the plates or on cross-sections cut from the plates. The experimental data were analyzed in terms of various parameters and functions capable of characterizing the orientation of the filler particles and of the polypropylene crystallites in dependence on the distance from the gate and from the surface of the plates. The results establish that Mg(OH)2 influences the orientation of the polypropylene crystallites only moderately, in spite of the pronounced orientation of the platy filler particles parallel to the mold surface, whereas other platy fillers like talc or graphite were found to exert a very pronounced orientation effect on the polypropylene matrix. The different efficiency of Mg(OH)2 may be explained by the poor ability of this filler to nucleate polypropylene.

In almost all parts of the world, including Britain, some invading species have had a marked impact on the abundance and distribution of the native biota. The com munities affected include natural and seminatural ones, although the effect of inva sions is better known in agricultural habitats. Because of the importance of this prob lem in some areas both economically and for conservation, SCOPE (the Scientific Committee on Problems of the Environment) initiated a programme in 1982 that com prised national meetings and international working parties. This volume records the papers and discussion at a Royal Society Discussion Meet ing in February 1986, which was the British National meeting under the SCOPE pro gramme. Partly because of the strong tradition of natural history in this country, British data on the distribution, spread and impact of invaders are as good as any. In recent years British ecology has been noted for its strength in quantitative studies, both analysis and modelling, so this national SCOPE meeting not only concentrated on the quantitative aspects of invasions in a British context, but also reports on the results of two of the SCOPE international working parties, on modelling invasions and on inva sions into nature reserves. Included in the papers in this volume there are discussions of invasions by plants, animals and microbes, of the importance of genetic and historical factors, and of mod els of different invasive processes. From the surveys of what is known of British invad ers and their characteristics there are critical discussions of the extent to which valid generalizations may be made in this field. The volume will be of interest to ecologists and conservationalists, to population geneticists and naturalists, and to adminis trators and planners concerned with invasive species and their effects.

We provide a Camusian/Peircean notion of inquiry that emphasises an attitude of fallibilism and sustained epistemic dissonance as a conceptual framework for a theory of classroom practice founded on Deep Reflective Thinking (DRT), in which the cultivation of collective doubt, reflective evaluation and how these relate to the phenomenological aspects of inquiry are central to communities of inquiry. In a study by Fynes-Clinton, preliminary evidence demonstrates that if students engage in DRT, they more frequently experience cognitive dissonance and as a result improve their ability to engage in further and more frequent DRT. Parecidos de familia Family Resemblances Propuestas actuales en Filosofía para niños Current Trends in Philosophy for Children 48 Sustained intellectual progress occurs when the inquiry reaches a point whereby students can thoughtfully move between the position of disequilibrium (doubt) and equilibrium (belief) whilst understanding the impermanency of any fixed belief, which, in turn, enables reconstruction of thinking and appropriation of learning in the context of collaborative philosophical inquiry.


This paper proposes a fuzzy bi-objective unit commitment optimization model considering source-grid-load interactions. On the one hand, the model combines economic objective and environmental objective reasonably, and it can deal with bi-objective optimization both with priority and without priority. On the other hand, the model takes the interactions between supply side and demand side of power system into account. Besides, we solve the optimization by a new approach, modified Particle Swarm Optimization employing Crossover and Mutation operators in Genetic Algorithm. Results of our research show that this model has the ability to balance economic benefits and environmental benefits. In addition, it is proven that source-grid-load interactions are of evident significance to make power system operation more environment-friendly, and the interactions may also have economic advantages during the peak-load period. This model can take advantage of demand side resources effectively to reduce emission and cost of power system.


Optimal control-based cooperative guidance laws, which enforce at intercept a relative geometry in between a group of missiles and a single maneuvering target, are presented. An example scenario of interest is that of intercepting a high-value target (such as a ballistic missile) by a team of cooperating interceptors arriving from different directions. The problem is posed in the linear quadratic framework, and closed-form analytic solutions are obtained for any team size with any linear missile dynamics. The performance of the cooperative guidance laws is investigated using a nonlinear two-dimensional simulation of the missiles' lateral dynamics and relative kinematics. It is shown that cooperatively imposing a relative intercept angle between the missiles provides substantially better results than when each missile independently enforces, using a one-on-one strategy, a preselected intercept angle that satisfies the relative intercept requirement. It is also shown that the missiles' acceleration requirem...


Abstract We study, from a quite general point of view, a CQ*-algebra (X, 𝖀0) possessing a sufficient family of bounded positive tracial sesquilinear forms. Non-commutative L2-spaces are shown to constitute examples of a class of CQ*-algebras and any abstract CQ*-algebra (X, 𝖀0) possessing a sufficient family of bounded positive tracial sesquilinear forms can be represented as a direct sum of non-commutative L2-spaces.


In today's global economy, human performance technology (HPT) professionals must understand how to help organizations as they make the transition to an international marketplace. Many organizations are realizing that they must make changes in their ''strategy, structure, design and performance'' as they operate in different cultural settings (Sanchez & Curtis, 2000, p. 57). Therefore, HPT practitioners should develop and implement performance interventions that fit various cultures yet remain aligned with the core values and traits that characterize and differentiate corporations (Schneider & Barsoux, 1997). In this context, the challenge for HPT is to gain a clear understanding of how factors like national and organizational culture influence the existing HPT framework (Addison & Wittkuhn, 2001; Carey, 1998). Specifically, studies examining the impact of culture on the use of HPT interventions are especially important because these are the strategies that practitioners rely on when they recommend solutions to performance problems. The issues involved with adapting human performance interventions to international settings are among the most challenging tasks facing the field (Laurent, 1986).


A method is described for determining the Pockels coefficient r63 of an electro-optic crystal simply by identifying and measuring the peak r.f. power that maximises or minimises the time-average transmitted-light intensity when the crystal is used to intensity-modulate light via the longitudinal electro-optic effect. Results are given for ADP at 5.5 GHz. The effect of modulator-cavity-endplate perforations is discussed.


A program of research was conducted to assess the performance of current and future CO2 separation technologies with respect to their exergy limits. The technical exergy analysis focused on two post-combustion separation systems—chemical absorption using MEA and vacuum-swing surface adsorption using zeolite 13X. The former was chosen as a well-vetted, canonical example of today's approach, and the latter as an example of a possible option for the future (perhaps using an advanced nano-engineered sorbent in place of the zeolite). The analysis showed that despite years of refinement, the MEAbased system had an exergy efficiency of only 9%. Perhaps more surprising, the largest loss in this system was avoidable—it is due to poor steam integration with the power cycle. In the case of the zeolite adsorption system, the exergy efficiency was much higher at 23%. But similar to the absorption system, its largest loss was also avoidable— it is due to a poor choice of how to generate the vacuum necessary for CO2 removal from the sorbent. The other thing the two systems have in common is that once the avoidable losses are corrected, the next most limiting loss is in the fluid contactors. In both cases, achieving a significant further improvement will require rethinking of how exergy is managed so as to reduce the driving chemical potentials in these units. Life Cycle Assessment was used to extend the boundaries of analysis beyond those normally used for a technical exergy analysis. Although exergy has been used in LCA studies before, significant extensions and adaptation was required for this work. In particular, a new method for incorporating exergy analysis into LCA was developed, referred to as Cumulative Exergy Intervention, in which both the exergetic resource drawdown and exergetic waste deposition are tracked. Using this method, it was shown that only a small fraction of the complex exergetic flows (0.02%) need to be specified to obtain a satisfactory analysis. This method was applied to the analysis of both natural gas and coal electricity generation, with and without CCS. This work showed that achieving reduced exergy discharge into the environment in the form of CO2 came at the cost of both increased exergy resource use (for example, to make MEA) and increases in other forms of exergy discharge (e.g., thermal exergy in flue gas and cooling water). This work also helped to show some key limitations of using exergy as a metric for environmental impact. Namely, difficulties associated with changes in the dead state over long time scales, and the sensitivity of the real environment—a driven, nonequilibrium system—to small, accumulating discharges of exergy (like CO2). Introduction This project had two main objectives. The first was to find how close candidate carbon-capture systems were to their thermodynamic limits. The second was to extend the boundaries of analysis of such systems using Life Cycle Assessment, and to do so using exergy as a key analysis tool. Both of these objectives were accomplished in the project. In addition, two secondary objectives were identified: to extend the analysis of the candidate technologies to include economics, and to work to extend an overall framework for comparing technologies on an absolute basis. These objectives were not accomplished due to complications encountered in the core technical analyses needed for the first two objectives. Simply stated, until the primary objectives were properly satisfied, it made no sense to add additional efforts (e.g., techno-economics) to the analysis. As such, the secondary objectives were released in favor of providing definitive, correct answers for the primary objectives. (It should be noted that a complementary project in GCEP has its primary focus on techno-economics, and that knowledge was in part responsible for our being comfortable with relaxing that effort.) Detailed exergy analyses were performed on two post-combustion carbon-capture systems: an MEA-based system modeled after one that has been extensively studied by NETL, and a relatively new vacuum-swing-adsorption (VSA) system using zeolite 13X. The former system was chosen both to quantify its performance and to provide a wellunderstood example of a canonical capture system. The latter was chosen as an example of a proposed advanced system with the potential for a significant reduction in the energy penalty for the separation. In addition to overall performance quantification, the distribution of exergy loss was established for both systems so that the most important targets for sub-process improvement were identified. In order to understand the economy-wide impacts of CCS technologies, a life cycle assessment (LCA) model was built to handle general exergy analysis of all direct and indirect impacts of a technology. Building off of Ecoinvent, the largest available database of industrial mass and energy flows, we constructed a "matrix reduction technique" to distill the most important flows associated with CCS-based power generation processes. We were then able to perform exergy analysis on these flows to determine the economywide drawdown of exergy resources, as well as the deposition of exergy to the environment in waste streams such as hot flue gas or cooling water streams. We then applied this method to a detailed reconstruction of a MEA-based CCS system to determine the plant-level and economy-wide exergy efficiencies. Background Carbon dioxide capture and storage (CCS) is a necessary part of any comprehensive strategy for achieving reductions in atmospheric carbon. Many studies of proposed carbon capture systems have been performed, including those produced as part of the IPCC process [1], those produced by the U.S. DOE [2], those from the IEA [3], and numerous academic and industrial analyses [4-6]. These studies conclude that existing options for post-combustion carbon capture lead to a significant loss of plant output—as much as 30%—when compared to a similar plant without carbon capture. These numbers might be acceptable were it not for the fact that thermodynamic limits suggest that much more efficient processes are possible. Considered in terms of the minimum work required to separate carbon dioxide generated by combustion of natural gas from its flue gas at atmospheric pressure, only a 2.4% loss of plant output is actually required [7]. And even with compression of the CO2 to 100 bar—the pressure prescribed by NETL for use in comparing separation options [2]—the fraction of exergy required only rises to 3.5%. These figures illustrate a key point: Assuming an exergy efficiency of ~50% for the overall plant, it should be possible to develop a separation methodology that meets NETL specifications while incurring only a 7% loss of plant output.1 This leads to a need to analyze the performance of carbon capture systems via an exergy analysis so as to understand their operation relative to this thermodynamic baseline. The objective of this type of analysis is to quantify the distribution of exergy within a system such that the causes of its destruction are exposed. With the exergy distribution of a plant or process known, not only is its overall quality assessed with respect to a fundamental, absolute yardstick, but the locations and magnitudes of losses are revealed for inspection and improvement. Exergy analysis provides both an unambiguous assessment of system quality and points the way to future process improvement. Our research takes the analysis beyond the traditional system boundary, incorporating global effects in the comparison of carbon capture systems. Using results from the exergetic systems analysis, we are conducting a life-cycle assessment (LCA) in order to better understand how a given CCS technology interacts with the environment at broad scales. This assessment includes not only direct energy consumption (i.e., exergy consumption) at a facility, but also the exergy destruction associated with all "embodied" materials and components, as well as the operational interactions with the environment. The goal of this analysis is to understand which technology option results in the smallest disruption to the environment and results in the smallest drawdown of valuable energy and material resources (e.g., exergy stores) across the entire supply chain. This will enable a better understanding of the tradeoffs between using sophisticated material inputs (which often require more embodied energy inputs) and reducing energy impacts on site. A number of LCAs have been performed of CCS technologies [8-10]. These LCAs serve to situate a CCS technology within the broader industrial ecosystem, tracking all material and energy flows both upstream and downstream of a technology of interest. In our case, this set of material and energy flows is utilized in an exergetic approach to LCA [11-13]. Several professional LCA datasets exist, such as the GaBi databases or the U.S. LCI database. After an overview of the available options, we chose to purchase the Ecoinvent Data life cycle assessment database, commissioned by the Swiss Centre for Life Cycle Inventories. The selection was based largely on the accessible nature of the raw database files, from which we could construct and manipulate individual matrices and perform exergetic life-cycle assessments without the utilization of a third-party LCA software package. 1 For example, the exergy efficiency of a modern (F-class) NGCC power plant is ~52%. Results The results of this project follow along the two lines described above—technical exergy system analysis and life cycle assessment. The results in each area are detailed comprehensively in a PhD thesis [14], two MS theses [15, 16], and a peer-reviewed publication [17]. A summary of the key results from each of theses comprehensive reports is given below. The theses themselves are available both from the authors and the GCEP website (as Appendices A-C).

Data fusion is a well-known technique, becoming more and more popular in the Artificial Intelligence for Earth Observation (AI4EO) domain mainly due to its ability of reinforcing AI4EO applications by combining multiple data sources and thus bringing better results. On the other hand, like other methods for satellite data analysis, data fusion itself is also benefiting and evolving thanks to the integration of Artificial Intelligence (AI). In this letter, four data fusion paradigms, based on Convolutional Neural Networks (CNNs), are analyzed and implemented. The goals are to provide a systematic procedure for choosing the best data fusion framework, resulting in the best classification results, once the basic structure for the CNN has been defined, and to help interested researchers in their work when data fusion applied to remote sensing is involved. The procedure has been validated for land-cover classification but it can be transferred to other cases.


psychology" (161). In addition to this Antologia, it is apparent that feminist and feminine literature was also a growing interest for anthologists during this period. António Salvado published three religious anthologies and two others completely dedicated to Portuguese women's poetry from 1969–1973. Much more radical were Natália Correia's contributions, ranging from the fairly tame Trovas de D. Dinis (c.1970) to the much more controversial Antologia de Poesia Portuguesa Erótica e Satírica (1965), among others. All of these anthologies serve to show the varied "contradictions or tensions in Portuguese cultural life" (180) and, while adding to Portuguese literary history, are also clear documents of the political and social currents of the time. Th e fi nal chapter of Baubeta's book focuses on anthologies from 1974 to the present (2007) and emphasizes the idea of revolution and innovation in literature. Many anthologies published in the late 1970s included literature previously censored by the Estado Novo, many texts began to explore heretofore prohibited topics such as the civil war in Spain, race, gender, identity and other topics, and the overall idea of "promoting literary culture" (193) though anthologies oft en brought back old favorites for didactic purposes. Overall, the overwhelming role of the anthology was for exploration and gaining knowledge, which is a trend that can be seen to the present day, and in Baubeta's extensive catalogue of anthologies for various literary genres which is followed by a detailed bibliography. In conclusion, I recommend this book for both early and advanced scholars alike, who should approach the book as a means for furthering knowledge. Many of the anthologies analyzed contain material that has not been canonized or perhaps even fully studied, and the catalogue and bibliography provide many indications of where to begin to search. As such, the book is an excellent tool and does, as Baubeta acknowledges, accomplish her initial goal: "At the beginning of this study, I asked whether anthologies limit our horizons of expectation or extend them. I believe that a study of anthologies cannot help but open up new avenues for exploration" (215).


Relatively speaking,compared to the equal election,the competitive election has its own development vein.The basic content of the competitive election means there are more candidates than deputy positions.By combing the development vein of the east and west electoral system and analyzing the situation of the execution on the competitive,the author points out that raising the competitive election actively is not only beneficial to the reform of the electoral system but also beneficial to the development of the democratic legal construction in our country.


This paper proposes two greedy heuristics based on an iterated insertion technique to solve the flexible job shop scheduling problem with transportation time's constraint. The approaches treat the two sub-problems of: the assignment of machines to operations and the sequencing of the operations on the assigned machines. The idea is to start with a greedy construction method, then, apply an iterative destroy and recreate algorithm, to minimise the maximal completion time of machines (makespan). The heuristics were tested on a benchmark that considers the transportation times between the machines and based on a real flexible job shop 'AIP-PRIMECA cell of Valenciennes University'. The results of the proposed heuristics are compared with the results of a mixed integer linear program (MILP) and the potential fields (PF) approach. The results obtained are very promising.

Using 1990 5% Census and American Community Survey data, we examine the economic integration of Afghan refugees to the US, focusing on employment rates and income levels. First-wave Afghan refugees (those arriving 1980-90) have made significant income and employment gains, while poverty rates and reliance on government assistance have decreased dramatically. The most recent wave is not doing as well at comparable points in time.


On 25 August 2020, the ESRF succeeded in opening its new Extremely Brilliant Source (EBS), a first-of-its-kind, new generation of high-energy synchrotron light source, to the international scientific community (Fig. 1). Also in 2020, the ESRF, like all institutes worldwide, had to deal with the COVID-19 pandemic, requiring us to adapt our strategy and find innovative ways to keep the facility operational while ensuring above all that the ESRF remains a safe place to work. The pandemic has highlighted, more than ever, the importance of state-of-the-art research infrastructures to contribute to providing a rapid, collective response to the vital challenges facing our society today.

Strigolactones (SLs) are a group of plant apocarotenoids that act as rhizosphere signaling molecules for both arbuscular mycorrhizal fungi and root parasitic plants. They also regulate plant architecture as phytohormones. The model legume Lotus japonicus produces canonical 5-deoxystrigol (5DS) and non-canonical lotuslactone (LL). The biosynthesis pathways of the two SLs remain elusive. In this study, we characterized the L. japonicus MAX1 homolog, LjMAX1, found in the Lotus japonicus genome assembly build 2.5. The L. japonicus max1 LORE1 insertion mutant was deficient in 5DS and LL production. A recombinant LjMAX1 protein expressed in yeast microsomes converted carlactone (CL) to 18-hydroxycarlactonoic acid (18-HO-CLA) via carlactonoic acid (CLA). Identity of 18-HO-CLA was confirmed by comparison of the methyl ester derivative of the MAX1 product with the chemically synthesized methyl 18-hydroycarlactonoate (18-HO-MeCLA) using LC-MS/MS. (11R)-CL was detected as an endogenous compound in the root of L. japonicus. 13C-labeled CL, CLA, and 18-HO-MeCLA were converted to [13C]-5DS and LL in plant feeding experiments using L. japonicus WT. These results showed that LjMAX1 is the crucial enzyme in the biosynthesis of Lotus SLs and that 18-hydroxylated carlactonoates are precursors for SL biosynthesis in L. japonicus.

IgG and IgA antibodies to Epstein‐Barr virus (EBV) membrane antigen (MA) were detected in sera from 96 NPC patients and normal individuals by the indirect immunofluorescence test. For MA/IgG antibody, 100% of NPC patients were positive with a GMT of 1:439.7 and 97.9% of normal individuals were positive with a GMT of 1:94.7. In contrast, for MA/IgA antibody, 58.3% of NPC patients were positive with a GMT of 1:7.3 and none of the normal individuals were positive. There was no difference in the detection of antibodies to EBV MA when other P3HR‐1 or B95‐8 cell lines, differing in their major membrane antigen, were used.

Objective
To analyze the result and adverse reactions of radiation therapy in patients with pelvic recurrence following cervical cancer postoperative.

Methods
A retrospective analysis of 147 patients with pelvic recurrence after surgical treatment of cervical cancer in the Fourth Hospital of Hebei Medical University from August 2004 to December 2016 was performed. All patients received radiotherapy with or without chemotherapy. According to different clinical factors and pathological factors, Logistic regression analysis was used to analyze the factors influencing radiotherapy outcomes in patients with pelvic recurrence after cervical cancer surgery. The Kaplan-Meier method was used to analyze the survival rate, and the corresponding survival curve was drawn. The survival rate and prognosis related factors were compared by using the log-rank test. The COX proportional hazards regression model was used for multivariate analysis of statistically relevant factors in univariate analysis. After treatment, toxicities were analyzed using chi-square test.

Results
The median follow-up time was 33.2 months. 95% of the patients completed radiation therapy with a dose of ≥67 Gy (median radiotherapy dose), and 91 patients (61.9%) had complete remission (CR). The 5-year local control (LC), progression-free survival (PFS), distant metastasis-free survival (DMFS), and overall survival (OS) were 63.6%, 56.0%, 73.9%, and 55.0%, respectively. Univariate logistic regression analysis showed that FIGO staging (stage 0-ⅠB and ⅡA-ⅡB), pelvic sidewall involvement, and recurrent tumor volume were associated with complete remission (P<0.05). Multivariate statistical analysis found that FIGO staging and pelvic sidewall invasion were independent factors influencing the efficacy and survival of patients with pelvic recurrence after cervical cancer surgery (P<0.05). Patients with pelvic wall invasion after cervical cancer surgery had a higher incidence of ≥grade 2 proctitis than those without pelvic walls involved, which were 26.9% and 16.7%, respectively.

Conclusions
This study shows that after the surgical treatment of cervical cancer patients with pelvic recurrence can be tolerated by toxicities after radiation therapy. In addition, the incidence of toxicities in patients with pelvic wall invasion was significantly higher than those without pelvic wall invasion. Preoperative staging and the pelvic wall involvement are independent influencing factors influencing the effect of radiotherapy and long-term prognosis in patients with pelvic recurrence after cervical cancer surgery.

As the number of installed Battery Energy Storage Systems (BESSs) increases, the concerns related to possible cyber-attacks to these systems rise accordingly. The most of BESS owners knows their systems may be vulnerable, but they often consider only denial of service attacks in their risk assessment. Unfortunately, other, subtler and more dangerous attacks exist. In this paper we show that a stealth attack to BESSs can be performed by applying a Man-in-the-Middle (MitM) approach. The aim of the attack is to stealthily manage the physical system by hiding the actual behavior of the system to its supervisory controller. In this case the attacker would be able to: (i) degrade the BESS by reducing its expected lifetime, (ii) produce economic losses for the prosumer, and (iii) affect the security and stability of the grid. The feasibility of the attack is demonstrated by providing an example of a stealth MitM attack on a real BESS coupled with a photovoltaic power plant. The proposed case study demonstrates that such attack can be performed without being discovered by end-users and shows that its effects can be severe. Finally, possible strategies to avoid or detect such kind of attack are discussed.


Turning of hard materials usually presents poor machinability. However, for high productivity, it is desirable to employ turning of hard materials rather than grinding. In this work, turning of hardened 16MnCrS5 steel with hardness of 43 HRC was explored to judge machining performance with plain and wide-groove-type chip-breaking TiC-coated carbide inserts under dry and wet environmental conditions, different cutting velocity, and feed. Tool wear tests were also done in dry and wet conditions. Satisfactory tool performance was observed under wet condition using TiC-coated plain and wide-groove carbide inserts even at 268 m/min cutting velocity, when dry machining could not be done effectively.


The invention provides a method for synthesizing alfa-methylpyridine through continuous catalytic distillation, comprising the following steps: in the presence of metallocene catalyst, letting liquid phase acetonitrile and gas phase acetylene continuously pass through a filling tubular reactor and be subject to reaction at the reaction temperature of 100-200 DEG C under reaction pressure of 0.5-2.0 MPa with the catalyst addition which accounts for 0.3-0.35 % of the total weight of acetonitrile and acetylene, keeping the reactant in the reactor for 20-60 min, and carrying out double-tower continuous rectification separation on the obtained crude product of alfa-methylpyridine to obtain the high purity alfa-methylpyridine.

Here,we presented the estimated NH4-N and TP budget in the Jiulongjiang Reservoir Reach in 2007 to find out the effect of nutrition retention.The results reveal that the amount of runoff and the nutrient flux were both high in the wet season and low in the dry season.The NH4-N was highly retained at a rate of 32%.While the TP retention rate was-10%,it is possibly because a large amount of TP was released from the sediments when the river was turned into a reservoir.

Background: Acute pancreatitis is a common surgical entity with a wide clinical spectrum ranging from mild pancreatitis to severe acute pancreatitis with lethal complications. A number of scoring systems have been devised to predict and manage complications associated with severe acute pancreatitis. The objective of this study was to study the demographics, early complications of acute pancreatitis with their outcome, and to assess the efficacy of multi organ system failure score. Methods: This was a descriptive study including 120 patients of acute pancreatitis done over a period of 2 years. The management of complications and their outcome were recorded in detail. A multi organ system failure score was used to predict and assess the severity of acute pancreatitis. Results: Total 120 patients were evaluated with mean age of 40 years and male preponderance. Alcohol consumption was the most common etiological factor. Acute fluid collection was the most common local complication while shock was the most common systemic complication. MOSF scoring system had a sensitivity, specificity and positive predictive value of 96%, 92.8% and 90.5% respectively. Mortality was 5.8% seen in patients with MOSF score above 5. Conclusions: The management of early complications of acute pancreatitis is mainly conservative, with surgical management limited to only a few selected patients. MOSF score is a valuable tool to predict and assess the severity of acute pancreatitis and should be used for monitoring of high risk patients.


Background There is conflicting evidence concerning the extent to which the intravenous general anesthetic thiopental acts by enhancing inhibitory &ggr;-aminobutyric acid–mediated (GABAergic) synaptic transmission or by inhibiting excitatory glutamatergic transmission. Yet there are remarkably few studies on the effects of thiopental on functional synapses. In addition, the degree of stereoselectivity of thiopental acting at synapses has yet to be tested. Methods The actions of thiopental and its enantiomers on GABAergic and glutamatergic synapses were investigated using voltage clamp techniques on microisland cultures of rat hippocampal neurons, a preparation that avoids the confounding effects of complex neuronal networks. Results Racemic thiopental markedly enhanced the charge transfer at GABAergic synapses without significantly affecting the peak of the postsynaptic current. At a surgically relevant concentration (25 &mgr;m), charge transfer was increased by approximately 230%. However, even at twice this concentration there were no significant effects on glutamatergic postsynaptic currents. At GABAergic synapses, thiopental acted stereoselectively, with the S(−) enantiomer being approximately twice as effective as the R(+) enantiomer at enhancing charge transfer. Conclusions Thiopental stereoselectively enhances inhibitory GABAergic synaptic transmission in a way that reflects animal potencies, supporting the idea that this is a principal mode of action for this drug. The absence of any effect on glutamatergic synapses at surgically relevant concentrations suggests that the inhibition of these excitatory synapses is not an important factor in producing thiopental general anesthesia.


THE ORIGINALS of this series of documents, known as the Preguntas y Respuestas, copies of which are preserved in the Santa Barbara Mission Archives, were written by the Franciscan missionaries of the nineteen missions founded in California between 1769 and 1804. They were answers to the questionnaire sent out by the Spanish Government in 1812 to all the civil and ecclesiastical rulers of the overseas dominions concerning certain cultural aspects of the native races in their original, pre-Christian state. The questionnaire was forwarded to California from Culiacari, Sinoloa, by the Bishop of Sonora, August 13, 1813. In California it was received by the Very Rev. Jose Sefian, O.F.M., president of the California missions. He in turn informed the missionaries of the government's request. Fortunately, at the time the missionaries sent in their official replies to the government, they retained copies for the Franciscan Mission Archives. These are the ones that are preserved at Santa Barbara. There are respuestas for eighteen of the nineteen missions then in existence—that of Mision Purisima, for some unknown reason, is missing.


The general objective for this study was to examine a relationship between Manpower Planning and Workload Imbalance in the Tanzania Police Force. The researcher wished to find whether not manpower planning had any impact towards workload imbalance in the Tanzania police force or other factors were in charge. Primary data were collected from police officers in Geita Police Commands. Research questionnaires were set on five-lickert scale whereby out of 150 targeted respondents only 125 respondents were able to respond for this study. Collected data were edited, coded, analyzed by using descriptive statistics, regression analysis and chi-square test whereby it proved that both manpower planning and premeditated factors were major factors contributed towards workload imbalance in the Tanzania police force. Study findings identified that Manpower planning positively explained workload imbalance in the Tanzania police force. The chi-squire proved that the study had to accept the null hypothesis that "Manpower planning had the impact towards workload imbalance in the Tanzania police". In this case, it was proved that poor manpower planning was the actual course of the workload imbalance in the Tanzania police force. Policy implication was drawn and stipulated that police leaders should build up good manpower deployment, good manpower placement, good manpower quality and good manpower quantity and they should avoid nepotism, ethnicity, corruption and bribery and sexual relations with their subordinates.

Key words: Manpower deployment, manpower placement, manpower quality, manpower quantity, workload imbalance and poor manpower planning.


Avian embryo thyroid responses to incubator temperature and oxygen concentrations during the plateau stage in oxygen consumption were measured. It was hypothesized that turkey embryo thyroid responds in a limited way at this critical time to environmental conditions to modulate basal metabolism. Turkey embryos were exposed to one of four incubator temperatures (36, 37, 38 or 39 C) beginning on the o 25 day of incubation at the onset of the plateau, a time when plasma thyroxine (T ) and triiodothyronine (T ) th 4 3 concentrations normally increase. Blood was collected and thyroid hormone concentrations were measured at pipping (27 day) and hatching (28 day). Elevated temperatures depressed T and T concentrations and th th 3 4 increased the T to T ratios. In a second experiment four oxygen concentrations (17, 19, 21 or 23% oxygen) 3 4 were provided to the embryos using identical procedures. The 21% treatment significantly reduced T and 3 T at pipping compared to all other treatments, but 23% oxygen increased plasma T and the T to T ratio 4 3 3 4 compared to all other treatments. The 17% oxygen treatment elevated T compared to all other treatments. 3 At hatching, 23% oxygen elevated T and T to T ratios compared to all other treatments. When temperature 3 3 4 and oxygen treatments were applied together in a factorial arrangement, temperature and oxygen affected T and T hormone concentrations independently but did not interact. Therefore, we conclude that 3 4 temperature and oxygen are independent stimuli of the avian embryonic thyroid gland during the plateau stage, and that incubator temperature and oxygen concentrations can modulate development of turke y embryos by changing plasma T and T concentrations. 3 4


One feature that distinguishes the new nations of Africa from many other developing areas is a profound commitment to formal education as the pre-eminent instrument of modernization. However, in spite of considerable efforts to diffuse schooling more widely, most contemporary African states still contend with generally low enrolments and marked inequalities in the diffusion of schooling.' Although these problems may be due partially to financial difficulties, shortage of teachers, or insufficient stimulus by the previous colonial power, there can be little doubt that inequality in educational provision reflects to a marked degree variable levels of educational demand among the populations. Contemporary leadership exhibits an ideological commitment to formal education, but such zeal is very unevenly diffused among the masses. Consequently a major educational research task is to examine factors influencing educational demand and to delineate the dynamics of educational growth. We are only now beginning to understand some aspects of the diffusion of education in the Western context; in the developing areas few data are available. There is, to be sure, no scarcity of opinion on the matter, but in the case of Africa there is little evidence that opinions stem from direct observation or systematic research.2 In rather crude fashion we can distinguish several general viewpoints concerning the problem of educational demand. One approach attributes low demand to the "organizational" characteristics of the school itself and to the idiosyncratic relationships be-


Examination of the 20 species currently included in Cyathodes Labill. has shown a number of distinct species groups that warrant recognition at generic level. Accordingly, Cyathodes Labill. s. str, is restricted to three species endemic to Tasmania, including one new species, C. platystoma C.M.Weiller, which is described below.


Advanced composite material consists of fibers of high specific strength and stiffness embedded in a stabilizing resin matrix of lower stiffness and strength. For composite structure, the longitudinal tension and compression are carried by the fibers. The matrix distributes the load between the fibers for the tension case and it stabilizes and prevents the fibers from buckling for the compression case. The fiber dominates the tensile properties and the matrix dominates the compression and in-plane shear. The lap shear joint where all of the load in the structural members is transferred through the joining fasteners. This paper presents joint strength for laminate of advanced composite material in the bolted joints. The single lap joints were investigated experimentally with respect to stabilized and unstabilized lap joints. The stabilized single lap joint means joints with out-of-plane rotational constraints. The unstabilized single lap joint is joint without out-of-plane deflection constraints. The standard angles 0 degree, +45 degree, -45 degree and 90 degree, in the laminate reference system, were used for ply orientation within a laminate. The composite material used in this paper is a carbon/epoxy unidirectional(UD) tape prepreg cured at 350F. A total of 112 single lap joint tests were conducted on specimens from 8 distinct laminates. The ASTM-D-5961M standard was used for stabilized and unstabilized single lap shear joints.


Contingency theory recognizes that an important factor of survival of the organizations is their attitude to adopt diverse type of structural configurations depending on the environmental changes. This article attempts to show that the pragmatic character of the contributions of this approach, sustained in the concept of Adjustment, is convenient to explain how organizations fulfill their aims of survival and growth, but it is incomplete to explain how they can fulfill their social function. This affirmation is illustrated from an analysis on the process of emergence and proliferation of the technical and technological programs in management in Colombia.


The finite difference (FD) method of monopole source is used to simulate the response of full-wave acoustic-logging in cave formations. The effect of the cave in the formation of borehole full-waves was studied. The results show that the radius of cave is not only linearly related to the first arrival of the compressional wave (P-wave), but also to the energy of the shear wave (S-wave). The converted S (S–S wave) and P-waves (S–P wave) are formed when the S-wave encounters the cave. If the source distance is small, the S–S and S–P waves are not separated, and the attenuation of the S-wave is not large, due to superposition of the converted waves. The S–P wave has been separated from the S-wave when the source distance is large, so the attenuation of the S-wave increases. The amplitude of the P and S–waves changes most when the distance of the cave to the borehole wall reaches a certain value; this value is related to the excitation frequency. The amplitude of the Stoneley wave (ST wave) varies directly with the radius of cave. If the radius of the cave is large, the energy of ST wave is weak. The scattered wave is determined by the radius and position of the cave. The investigation depth of a monopole source is limited. When the distance of the cave to the borehole wall exceeds the maximum investigation depth, the borehole acoustic wave is little affected by the cave. In actual logging, the development of the cave can be evaluated by using the first arrival of the P-wave and the energy of the S and ST waves.


Extending a theorem of Shelah we prove that fundamental groups of Peano continua (locally connected and connected metric compact spaces) are finitely presented if they are countable. The proof uses ideas from geometric group theory.


The electrophysiologic properties of tocainide were evaluated by electrophysiologic studies in 11 patients before, during and after a constant intravenous infusion of the drug for 15 minutes. Peak plasma tocainide concentrations averaged 11.0 +/- 1.7 microgram/ml (SEM), range 3.7 to 22.7. AH, HV, QRS, QTc and RR intervals were measured every 5 minutes during sinus and atrial-paced rhythms and showed small changes which were not statistically significant for HV and QRS. Mild shortening of RR was significant (P less than 0.05) at 15 minutes only. AH tended to increase slightly for spontaneous (but not paced) rhythm, becoming significant at 15 minutes only (P less than 0.05). QTc decreased slightly, a change which was significant (P less than 0.05) for paced but not spontaneous rhythm. A progressive rise in mean arterial pressure occurred during infusion and persisted through 30 minutes (P less than 0.001). Comparison of electrophysiologic studies at 0 and 30 minutes showed decreased in mean effective refrac...


This study was conducted in Roopnagar and Patiala districts of Punjab state in order to assess the level of adoption and knowledge of farmers on mineral mixture and interaction of these factors in defining the level of knowledge. A total of 137 farmers were randomly selected and data were collected with a pretested questionnaire and knowledge test through an interview schedule. The results indicated that 22.62% farmers have adopted the technology of supplementing mineral mixture and 21.46% have adopted it partially. About 71.53% respondents used calcium supplements with or without mineral mixture. About 45.3% respondents had low level, 15.3% respondents had medium and 39.4% farmers had a high level of knowledge regarding use of mineral mixture. Approximaely, 50.4% farmers knew that mineral mixture has to be fed by mixing with concentrate mixture while only 10.9% knew that it can be mixed with green fodder too. About 9–16% respondents had the knowledge on categories of animals to be fed mineral mixture. 11–19% respondents had the knowledge that mineral mixture can positively affect milk production. However, awareness on deficiency symptoms like anoestrous, abortion, pica, indigestion and prolapse was as high as 48%. Higher education, bigger herd size, more frequent use of information sources, training and contact with extension agents affected (P<0.05) the knowledge level while age was found to have a non-significant effect.

Based on the analysis of the real traffic system and the research on the former simulation software,the authors propose that"model simulation"and"application simulation"are of the same importance,while"application simulation"is often em-phasized and provided in simulation software system.According to this i dea,the microscopic urban traffic s imulation system is designed which is a distributed rese arch platform for the traffic project and the traffic participant is base d on dynamic model and decisive model.In this simulation s oftware system,the purpose of"model simulation"is to validate the traffic participant model and improve them,and that of"application simulation"is to validate and improve a traffic management project by the use of the improved and validated traffic participant model.This paper introduces the detailed i dea of traffic participant model use d in simulation system.The design of traffic partic-ipant model aims at the Chinese actual traffic surroundings including th e bike model,car model and pedestria n model.These models have been validated and impro ved through module of"model simulation"and will be used in the module of"application simulation"to simulate some material traffic ap plication.Based on the idea of"model simulation"and"application simulation",this paper carries out the needed analysis of the simulation system and in troduces the system configuration o f the simulation software which can realize the functions of"model simulation"and"application simulation".In order to develop a reusable and interactive system easily,a Web thr ee-layer architecture is proposed,which realizes the three-module sep aration of data storage,simulation computing and graphical displaying.Due to the merits of the Web three-layer architecture,it is p ossible for the simulation software system to serve for the large-scale traffic simulation in the future.


IHE title of the paper which I am going to read to you is "Jewish Contributions to the British Textile Industry." The sub-title is "Builders of Bradford" as it deals almost exclusively with the development of the Bradford Textile Industry. You will hear the expression "piece goods" or "pieces" which to people not connected with the Textile business may sound somewhat strange. For their benefit I should like to explain that a "piece" in the Bradford area is generally a length of worsted cloth about sixty yards long and fifty-four to sixty inches wide, doubled up edge to edge lengthways and then rolled or cuttled for convenient handling and packing. I should like also to explain briefly the meaning of "shorts" and "damages" as used in this paper. When the pieces arrive from the mill at the merchant's or shipper's warehouse each piece is remeasured and "perched" or examined for faulty places or damages. When the account for goods supplied is paid to the cloth-manufacturer, deductions are made for any short measure or damage. Some shippers were rather too exacting in their examinations. With these preliminary remarks we can now proceed to the subject matter. The City of Bradford in Yorkshire is known throughout the world as the centre of the wool textile industry. Its greatest development as such took place in the second half of last century, when numbers of immigrants, for the most part German Jews, settled there and engaged in an intensive and extensive export trade of textile goods manufactured in Bradford and the surrounding district. The pioneer and principal of all these immigrant merchants was Sir Jacob Behrens who came to Yorkshire in 1832 from Hamburg where his family was established in the textile business. In 1934 when the firm of Sir Jacob Behrens and Sons Ltd., celebrated its centenary, the Bradford newspapers printed special supplements giving the story of the growth of the firm which is closely bound up with the growth of Bradford as a wool textile centre. Here is an extract from the Yorkshire Observer Centenary Supplement of December 6th, 1934.

Consumption of alkyl leaded gasoline has decreased considerably in the United States over the last 15 years. In order to evaluate the chemical response of the ocean to decreased atmospheric deposition of anthropogenic lead, new 210Pb and stable Pb data have been obtained near Bermuda (June 1983 to December 1984). Concentrations of these tracers in the mixed layer are highly variable during the period of observations (+/− 25%). From June through September, soluble eolian deposits accumulate in the shallow mixed layer because mixing and productivity are inhibited by the seasonal thermocline. In the fall, these enriched surface waters mix with upper thermocline waters, and surface Pb concentrations decrease. In the winter, storms from the east coast of North America cause local episodes of high Pb and 210Pb input into the ocean surface; the resulting areally-limited high Pb concentrations are dispersed within less than 2 weeks by vertical and horizontal mixing. Pb/210Pb ratios in surface waters are almost invariant over this period (averaging 669 pmol/dpm, ranging from 564 to 718 pmol/dpm). Surface Pb/210Pb appears to have declined by a factor of 2 since 1979, similar to the 2.6-fold decrease in U.S. leaded gasoline consumption during this period. A substantial fraction (on the order of 10%) of gasoline Pb is transported into the ocean. Pb concentrations in the upper thermocline may have declined by about 15% from 1979 to 1984. The helium-tritium thermocline ventilation model of Jenkins (1980), coupled with boundary conditions appropriate for Pb and 210Pb, shows that the supply of Pb and 210Pb to the thermocline is dominated by lateral isopycnal ventilation. The shape of the vertical profile is dominated by this physical ventilation, near-surface biological removal processes, in-situ scavenging, and (for stable lead) time-dependent input. Vertical transport by particles is responsible for minimal transport of dissolved lead into the upper ocean. Similar processes are likely to account for the plutonium maximum in the thermocline of the North Pacific. Observations of Pb and other reactive species in winter surface outcrops of thermocline isopycnals would provide valuable constraints on chemical processes within the thermocline.


CONCLUSION: Students achieved the recommended 10,000 steps daily goal on M/W/F and did not meet the step goal on T/Th. This difference in steps could be attributed to the mandatory no class 'common hour' which may allow students to be more physically active than the T/Th schedule. In addition, the shorter class structure on M/W/F (50 min/class) might also provide opportunities for students to be more active than T/Th (75 min/class). These preliminary results may be useful for planning early physical activity interventions on specific days of the week among college students.

Abstract The child-rearing beliefs of 32 mothen and 36 day-care providers in Mexico were compared. Day-care providers expected children to master developmental skills at an earlier age than did mothers. Day-care providers more strongly valued the development of independent and cooperative behavior. and placed less importance on obedience. The y also reported employing more flexible and nonauthoritarian discipline strategies than did mothers. Mothers and caregivers did not differ in the extent to which they attributed the success of their discipline strategies to their own actions rather than to external factors. Also examined was how mothers' beliefs differed in families characterized by interdependent versus individualistic social structures. In interdependent families, mothers were more likely to believe in later mastery of developmental skills and to make external attributions. The se fmdmgs suggest that Mexican children experience incongruous social norms as they move between home and day care setting...

The ability to accurately measure chlorine or other disinfectants in water is important for control of microorganisms. Whereas amperometry is specified for chlorine in Standard Methods for the Examination of Water and Wastewater, manufacturers of automatic titrators are marketing their potentiometric devices for such titrations. In this article, the electrochemical basis for amperometric and potentiometric endpoint detection is examined, and two amperometric and two potentiometric methods are compared. Both amperometric methods are shown to be superior to potentiometric endpoint detection and amenable to automatic titration. Finally, fundamentals of amperometry are discussed, and the simple circuit that was used to perform amperometric titrations using a modified automated pH/potentiometric titrator is presented.


Introduction: In recent years, with the rapid advancement of technology, tools capable of minimising discomfort for the diabetic patient are becoming increasingly popular, thereby increasing adherence to treatment. The use of technology improves glycometabolic compensation and quality of life. Objective: The aim of the present study is to verify, in the group using the Flash Glucose Monitoring system, improved diabetes management and satisfaction in insulin-treated patients. Materials and Methods: A retrospective cross-sectional study was performed through the administration of the "Diabetes Treatment Satisfaction Questionnaire". The study was performed from January to July 2019. 82 validated questionnaires were administered in the Italian version. Participants were 47 women (39 Type 1 Diabetes Mellitus and 8 Type 2 Diabetes Mellitus) and 35 men (19 Type 1 Diabetes Mellitus and 16 Type 2 Diabetes Mellitus). Results: Results show that subjects with the Flash Glucose Monitoring system have greater satisfaction than those using the Self-Monitoring of Blood Glucose system. Patients using Flash Glucose Monitoring showed 83.9% satisfaction, while patients using Self-Monitoring of Blood Glucose showed 33.3% complete satisfaction. The average glycosylated haemoglobin of the group of subjects using Flash Glucose Monitoring was 53.2 mmol/mol, while that of subjects with self-monitoring of capillary blood glucose was 60.3 mmol/mol. Conclusions: The adoption of new technologies has benefits for the patient that positively affect quality of life. The study showed better glycometabolic compensation in the group of patients using Flash Glucose Monitoring. Diabetes carries significant costs to public health, and prevention and improvement of care could be a primary goal for the community and health systems.

The notion of gender, introduced into France by queens and drags in the late 20th century (the glorious period of the "drag-queens") and revitalized by American "queer", follows a traditionally feminist path where homosexual and particularly male issues are once again being hidden away. Having played a big part in popularizing that first version, Patrick Cardon proposes, in order to avoid any misunderstanding and escape once for all from any attempts at reification, to use the term and the universal notion of transgender, which would cover the deconstructivist notions of queer, post-colonial and cultural studies, in order to give a place intelligently to ALL diversities beyond any binarism and with a foresight of future hybridity.


As this 11.1 issue goes into production, it is with great delight and some pride that we can celebrate the completion of ten years of TDPT. The journal, founded by Simon Murray and Jonathan Pitches, was and remains a much needed response to the growing networks of practitioners, artists and scholars who consider that the skills, knowledges and histories embedded in training for performance are worthy of rigorous research. Looking back at the first editorial in issue 1.1, Pitches and Murray reveal both the excitement at the enterprise of starting a journal of this nature and a certain trepidation at the range of potential problems they faced. In particular, their concern was with 'all the conundrums associated with "writing training" [that] seem to be exposed' (2010: 1). They recognised the challenges involved in calls from practitioner/ scholars such as Alison Hodge in the first edition of Twentieth Century Actor Training (2000) and Simon Shepherd in Performance Research: On Training (2009) for a meta-language and concluded, 'if we look back in another decade at the indexes of Volumes 1–10, we hope it will have at least offered multiple answers to the challenge (2010: 3). Many of the provocations raised in that first editorial have been at the heart of submissions and special issues that have followed, addressing the diversity of training processes that were interdisciplinary, inter-and intra-cultural, collaborative, digital, international. So too, the fields of performance training have proliferated as articles or guest editors open up perspectives and dig into processes taking place within specific national traditions, beyond the studio, outside of the conservatoire, or enriched and accumulated in specific training places. Ten years of the journal trace an array of visual and textual methods that wrestle with this question of how we go about 'writing training', extended in 2015 through the introduction of the TDPT blog. This platform with its enthusiastic, dedicated team of associate editors responded to the increased demand for space to host video, audio and immediate discussions on training. Free for all, it has increasingly become a welcome space into which the journal expands and interweaves but that also has a life of its own, with opportunities for interviews, discussions, artists' award pages and digital play. As plans go ahead to blow out the candles on TDPT's 10 birthday cake, simultaneously we celebrate the move from three to four issues per year. The growth of the journal from its original biannual set-up and its ability to be responsive to the changing national and global contexts for performance and performance training rests on the incredible support offered by associate editors working on Training Grounds, the blog and in generating new submissions/proposals, alongside the wider editorial board. We are fortunate in having such staunch support from Routledge colleagues who help in navigating a rapidly changing publishing world and who greeted expansion enthusiastically.


A new closed-form expression for the partial cancellation factor (PCF) in a multistage partial parallel interference cancellation (PPIC) receiver is introduced. This approach has several advantages compared to a previously proposed method. First of all, PCFs are found directly from the moments of the eigenvalues of the correlation matrix. This results in less complexity in circuitry. In addition, there is no need that the PCFs be ordered. Therefore, a monotonically improving performance is obtained with even more reduced complexity. Finally, it is not necessary to know the number of interference cancellation stages a priori. It is shown that by choosing these PCFs, the performance of PPIC receiver converges to that of the minimum mean-squared error (MMSE) receiver.

Since the first publication in 1989 [1] on the concept of resonant interband tunneling (RIT), there has been a large number of papers reporting on experimental demonstration and theoretical investigation of the three different versions of the RIT devices proposed by Sweeny and Xu I2l. The-results presented in these papers confirm that resonance effects are greatly enhanced with the combination of interband coupling of quantum levels and bandgap blocking. They also show that the concept of RIT is applicable to polytype heterostructures, homojunction delta-doped stnrctures and p n -j unction hetero st:lJcture.


The numerical simulations of the multi-element airfoils are realized by an explicit gridless method. Only clouds of points instead of grids are distributed over the computational domain and the spatial derivatives of the Euler equations are estimated using a least-square curve fit on local clouds of points. The paper gives discrete form for Euler equations on base of gridless method, and five steps of Runge-Kutta are adopted for time-marching . In addition, the paper describes a convenient technique of distributing points and selecting points to constitute clouds of points. The numerical results have been obtained for the flows over complex multi-element airfoils using the method presented.

Throughout this essay we approach the current environmental problems in our country, and teaching Environment, from the field of constitutional law. The process of "constitutionalisation" of the environment is examined from the law and environmental principles, delving into the protection concept "thing" (environmental goods), through constitutional right (from the realm of the subjective right of persons) evaluating the so-called "constitutional crisis", by the matter is already regulated, therefore the matter is already regulated, and the lack or shortage of this regulation within our Constitution, and the importance of knowledge of each and every one of them in order to promote their research and teaching. It is intended to indicate that the environment, understood as a constitutional right, whose content and environmental claims may be accompanied by other rights better protected by the laws, and wherein the same procedure juxtaposing claims, could be articulated in our legal environmental rights sheltered under invocations of other constitutional rights, with a greater degree of protection, which together with the new provisions of our courts, would environmental law a right, not understood as something abnormal product of a series of exceptional needs and problems that should be resolved in the future, but as a reality that contribute to introducing it as a subject in which the defendant is able to provide solutions and current, simple, effective and quick responses.


Discontinuation of long-term lithium treatment leads to early and severe affective recurrences [Baldessarini et al. 1999], and to a bipolar disorder course more severe than that before lithium treatment with an increased risk of suicide [Post, 2012], which is often resistant not only to other mood stabilizers, but also to the reinstitution of lithium treatment at the prior effective serum lithium level [Post, 2012].

Unfortunately, the currently available lithium-alternative mood stabilizers are of limited (anticonvulsants) [Geddes et al. 2010; Kessing et al. 2011; Greil and Kleindiest, 1999], or questionable (atypical neuroleptics) [Goodwin et al. 2011] efficacy.

We have recently provided clinical observations strongly suggesting that memantine, a noncompetitive N-methyl D-aspartate receptor antagonist, has a clinically relevant antimanic and a sustained mood-stabilizing effect in treatment-resistant bipolar disorder with excellent safety and tolerability [Koukopoulos et al. 2010, 2012; Sani et al. 2012; Serra et al. 2013].

More recently we have observed a long-lasting mood-stabilizing effect of memantine after lithium discontinuation in a bipolar I patient [Serra et al. 2013].

In order to evaluate further the effect of memantine in the prophylaxis of affective recurrences occurring after long-term lithium discontinuation, we administered the drug to three patients who had to discontinue lithium because of severe renal complications (two patients) or excessive tremor (one patient).

These case histories confirm our previous observations, and suggest that memantine may be considered a useful lithium substitute to prevent the affective recurrences after lithium discontinuation.

Case 1
Woman born in 1930, suffering from a bipolar II disorder with rapid cycling course.

She has a family history of bipolar disorder.

Her first affective episode was a depression in May 1979 (aged 49 years), followed by a hypomania until January 1980. She started lithium prophylaxis and had a very good response to lithium.

In June 2009 lithium was gradually reduced to 150 mg every 2 days (serum lithium level 0.2 mmol/L) and then withdrawn because of renal impairment. After we had obtained the informed written consent, she was put on 20 mg/day memantine and lamotrigine (250 mg/day). She started with rapid cycling recurrences until May 2010. Since then she has been well and stable on memantine 20 mg/day, lamotrigine 250 mg/day and lithium 150 mg every 2 days (lithium serum level 0.2 mmol/L).


The thermal convection in a porous medium is studied through the nonlinear interactions (normal forms) of the static state instabilities, in two cases: 1) one mode is marginally unstable; 2) tow modes become simultaneously unstable. From this study, in each case, models corresponding to different truncations of the Darcy-Boussinesq equations, are numerically studied. They allow to predict dynamical behaviours which are not described by the usual amplitude equations. Higher order truncations keep qualitative aspect of some solutions, in the problem parameters-space Etude des interactions non lineaires des instabilites de la solution de conduction dans deux cas: 1) un seul mode est marginalement instable; 2) deux modes deviennent simultanement instables.

First, a model of static data flow computer and a model of data flow graph are pro-posed; then a model of system is presented to calculate practical parallelism degree withoverhead of instruction execution on data flow computers as its parameter. From the compu-tation, the maximum practical parallelism degree of a program running on a static dataflow computer is determined with MP/OH (MP is the mean parallelism degree of a program,OH is the overhead of instruction execution on the computer). Therefore the overhead hasgreat influence on the performance of a data flow computer.


In this research, we study the use of fiber-reinforced concrete, including steel fiber-reinforced concrete in the construction of outrigger floors of a high-rise building. The definition and classification of fiber-reinforced concrete as a construction material, the methodology for calculating high-rise buildings using fiber-reinforced concrete, the advantages and disadvantages of this composite material, and the specifics of its use are formulated. The domestic and foreign experience in use of fiber-reinforced concrete is analyzed. The rationale for its use on the experience of construction of residential building in seismically active regions is given. A comparative analysis of concrete and fiber concrete use in the outrigger floors' construction is carried out.


This paper presents a model of generic entry competition that captures salient features of the HatchWaxman Act, enacted with two incompatible objectives of restoring incentives for new drug development and stimulating generic competition. For the latter objective, Hatch-Waxman eases FDA approval procedures for generics, and encourages patent challenges by granting marketing exclusivity rights to the first patent challenger. We show that the two entry-promoting measures complement each other in restoring innovative incentives. While branded and generic drug manufacturers' interests are opposed in general, there are cases in which they all benefit from marketing exclusivity. The welfare implications are also examined.


Strong localization effects are observed in epilayers of GaN and InGaN. We relate them to microstructure characteristics of samples studied. The same mechanism of localization is shown to be the dominant in GaN and in InGaN. Influence of strong localization effects on light emission properties is discussed.© (2001) COPYRIGHT SPIE--The International Society for Optical Engineering.

Planar single-gate (SG) silicon (Si) tunnel field effect transistors (TFETs) are attracting interest for ultra-low voltage operation and CMOS applications. For the achievement of subthreshold swing (S.S.) less than thermal limit of Si MOSFETs (S.S. = 60 mV/decade at 300 K), previous studies have proposed the formation of a pocket region, which needs very difficult implantation process. In this work, a planar SG Si TFET without pocket was proposed by using the technology computer-aided design (TCAD) simulations. An average S.S. of less than 60 mV/decade for 0.3 V (= Vgs = Vds) operation was obtained. It is found that both low average S.S. (= 27.8 mV/decade) and high on-current Ion (= 3.8 µA/µm) are achieved without pocket doping by scaling the equivalent oxide thickness (EOT) and increasing the gate-to-source overlap length Lov.


In this paper we consider a labour constrained scheduling problem which is a simpliication of a practical problem arising in the industry. Jobs are subject to precedence constraints and have speciied processing times. Moreover, for each job the labour requirement varies as the job is processed. Given the amount of labour available in each period, the problem is to nish all the jobs as soon as possible (minimise makespan, subject to the precedence and labour constraints). Several Integer Programming (IP) formulations for this problem are discussed and valid inequalities for these diierent models are introduced. We point out to the major drawbacks in using the IP approach which are essentially due to the weakness of the lower bound relaxations. However, we report computational experiments showing how IP can be used to provide good feasible solutions and we indicate directions for further investigations which may turn IP techniques an interesting tool for solving such a problem.

A methodology is presented for health monitoring and subsequent inspection of critical structures. Algorithms have been developed to detect and approximately locate damaged regions by analyzing signals recorded from a permanently mounted, sparse array of transducers. Followup inspections of suspected flaw locations are performed using a dual transducer ultrasonic approach where a permanently mounted transducer is the source and an externally scanned transducer is the receiver. Scan results are presented as snapshots of the propagating ultrasonic wavefield radiating out from the attached transducers. This method, referred to here as Acoustic Wavefield Imaging (AWI), provides an excellent visual representation of the interaction of propagating ultrasonic waves with the structure. Pre‐flaw and post‐flaw ultrasonic waveforms are analyzed from an aluminum plate specimen with artificially induced damage, and the AWI results show the location and spatial extent of all of the defects.

of -dibromides to is in organic synthesis a double bond protection-depro-tection strategy. A number of methods for effecting debromination have been developed, but most require long reaction times or elevated temperatures. It has been reported that Cp 2 TiCl 2 /Zn system can be used for a reductive debromination of vic -dibromides 1 to alkenes 2 . 3 We have found that various vic -dibromides 1 on treatment with Cp TiCl 2 /In system in THF are also smoothly converted into the corresponding alkenes 2 in good to excellent yields. In comparison with Cp 2 TiCl 2 /Zn system, the reactions using Cp 2 TiCl 2 /In system are fast and high-yielding. The chemical of Cp 2 TiCl 2 /M system (M=Na, Al,


ABSTRACT A method of designing and evaluating HMI (human–machine interaction) is proposed for the design in supervisory control of fully digitalized I&C (instrumentation and control) and digitalized human–machine interface system, which is a large-scale complex system in the NPPs (nuclear power plants). The proposed method consists of plant accident scenario simulation, knowledge base establishment, and interaction simulation. The plant accident scenario simulation is to analyze the plant behavior and system sequences under the predefined conditions; the knowledge base is modeled based on the simulation results as human and machine roles; and the interaction simulation is to simulate the interactions such as between operator and plant, operator and technical advisor. The proposed method utilizes the object-oriented software named plant DiD (defense-in-depth) risk monitor with the combination of accident simulation by an advanced nuclear safety analysis code such as RELAP5/MOD4. The practical developments for the details are demonstrated using an example practice for the SBLOCA (small break loss of coolant accident) case of passive safety PWR (pressurized water reactor) AP1000.


Analytical studies reveal that for a four-wheel-drive tractor with rigidly coupled drive axles to achieve the optimum tractive performance under a given operating condition, the theoretical speed (the product of angular speed and free rolling radius) of the front tires must be equal to that of the rear tires, or the theoretical speed ratio must be one. This paper presents tractive performance test data obtained using an instrumented four-wheel-drive tractor with seven different sets of tires at various theoretical speed ratios. Field data confirm the analytical findings that when the theoretical speed ratio is equal to one, the slip efficiency and tractive efficiency reach their respective peaks, the fuel efficiency (the ratio of drawbar power to fuel consumed per hour) reaches a maximum, and the overall tractive performance is at an optimum. It is concluded that to achieve optimum tractive performance in the field, proper matching of front and rear tire sizes and careful control of the inflation pressure and normal load of the tires to ensure the theoretical speed ratio equal or close to one are of practical importance.

Natural forests have many ecological, economic and other values, and sustaining them is a challenge for policy makers and forest managers. Conventional approaches to forest management such as those based on maximum sustained yield principles disregard fundamental tenets of ecological sustainability and often fail. Here we describe the failure of a highly regulated approach to forest management focused on intensive wood production in the mountain ash forests of Victoria, Australia. Poor past management led to overcutting with timber yields too high to be sustainable and failing to account for uncertainties. Ongoing logging will have negative impacts on biodiversity and water production, alter fire regimes, and generate economic losses. This means there are few options to diversify forest management. The only ecologically and economically viable option is to cease logging mountain ash forests altogether and transition wood production to plantations located elsewhere in the state of Victoria. We outline general lessons for diversifying land management from our case study.


. This study aims to examine the form of collaborative actions of advocacy actors, i.e. government and NGOs (communities) in policies related to domestic violence handling in the Municipality of Malang, Indonesia during the time of the COVID-19 Pandemic, and to analyze the supporting as well as inhibiting factors. Several actors collaborated in advocacy efforts; namely The Women's Empowerment & Child Protection, Population Control & Family Planning Agency and Women and Children Integrated Service and a non-governmental organization (community) called WCC Dian Mutiara also participated in these efforts. Results showed that the Women's Empowerment, Child Protection, Population Control and Family Planning Agency, the National Policewomen and Children's Protection Units, the Health Agency, the Social Services Agency, the District Court and the Woman Crisis Center Dian Mutiara had collaborated in advocacy efforts, supported by the existing Regulation Number 12 of 2015 and an intensive public education, but inhibited by public perception of domestic violence and their weak synergy.

GridFTP is a high-performance, secure, and reliable data transfer protocol that is being widely used in data transmission in Grid computing. A GridFTP server needs to achieve high throughput as it sends and receives data to and from multiple sources, each with its own configuration. Profiling tools can potentially help GridFTP administrators gain insight into the system's activities and identify configuration tradeoffs as well as potential bottlenecks. This paper presents a new profiling tool, called FTProfiler, which is built upon standard system profiling tools OProfile and Sar, to provide a more complete view of the system and simplify the profiling process for new GridFTP servers. FTProfiler calls OProfile and Sar, analyzes their profiling results and generates a detailed report. Through a case study, we show how FTProfiler can help administrators understand the effects of system parameters such as the TCP buffer size, block size, and parallel TCP streams on server performance and load, thus simplifying the process of detecting bottlenecks and tuning for performance.


This study was carried out to determine the "The Role of Learners as a Determinant Factor for Quality Education in Bauchi State primary schools." This study employed Ttest statistics and mean in analyzing the data collected. The population for the research constituted teaching staff drawn from lower basic primary schools of 2013/14 Academic session. Altogether, 180 teaching staff were randomly selected and used out of the 18 selected primary schools of the state. Information ware obtained through school interview and questionnaires. The findings of the study revealed that most Primary School Pupils cannot read, write nor communicate effectively in English language. They tend to have nonchallant attitude toward studies. In short, they don't have the spirit of hard-study habit. All these accredited to poor quality education in primary schools of the state.


By carrying forward the tradition of the neoculture,modern Chinese Left-wing literature is critical of the traditional family ethics, and consequently,the family heroes endowed with traditional ethics are transformed into the proletarian revolutionary soldiers in the writing.As a mater of fact,what is transformed involves not only the heroes but also the entire discourse and order of life.Nevertheless,instead of vanishing truly from the revolutionary field of discourse,the family ethics has returned to it in a special manner,thus having become a component of the new revolutionary discourse order.


This paper presents an analysis of wheel wear as a function of the relationship between the lateral and longitudinal primary suspension stiffness and the coefficient of friction at the centre plate between the wagon body and the bolster. The objective is to further minimise the wheel wear rate of a self-steering three-piece bogie without compromising vehicle stability. Simulation results indicate that wheel wear is theoretically the lowest for low lateral and longitudinal primary suspension stiffness and no friction at the centre plate. As zero friction at the centre plate is impractical, a low coefficient of friction and a low primary suspension stiffness were chosen as the optimum.


Abstract To identify and prioritize natural areas for consideration as research natural areas (RNAs) on the Superior National Forest (National Forest hereafter NF) in northeastern Minnesota, we developed a six-step approach that could be applied to natural area selection anywhere. Our goal was to select a limited number of sites to represent the NF's landscape and local ecosystem diversity. We also sought to minimize management conflicts. The steps are: (1) review existing information to create a list of potential sites; (2) develop a scoring system and score sites based on attributes that assess "natural area" quality of sites from maps, data, and other office information; (3) list ecosystems represented by each site and review sites based on their quality scores and the ecosystems they represent; (4) conduct field evaluations to confirm ecosystem quality for as many high scoring sites as feasible; (5) integrate the information from steps 1–4 with regional and local guidelines for conservation goals, ecosystem representation, and standards for site quality; and (6) review sites to minimize management conflicts and to maximize ecosystem representation and document the findings. Even with limited funds, using the six steps, we pared down the list from 114 to 41 sites for consideration in forest planning. Managers later used results to select 11 of the 41 sites for RNA establishment.
