This paper examines the impact of the Malaysian Syariah Advisory Council's (SAC) decision on stock eligibility. Specifically, we address four questions related to returns and trading volume of stocks in relation to the SAC's decision to add or delete a stock to their list of halal stocks. Overall, our findings suggest that inclusions experience a positive impact while deletions negative. Our sample of 39 inclusions showed positive MCAR and increased trading volume. The price impact however was delayed with significant positive MCARs in the 30 and 60 day window periods following announcement. The impact on trading volume appears immediate but short lived. Our Sample of 21 stocks deleted from SAC list experienced negative MCAR and reduced trading volume. These were however statistically significant only in the 60 day window post announcement.


In this article, Alison Stone reconsiders mother–daughter relations in the context of Christine Battersby's work, in which she attempts to resituate the female subject position as norm. Following Battersby's lead, Stone attempts to resituate the daughter's subject position as norm rather than as pathological, by virtue of the daughter's incomplete separation from her mother. It is argued that Luce Irigaray, who is also concerned to revalue mother–daughter couples, imagines them as harmonious and unified. It is necessary, instead, to understand mother–daughter relations as taking place within a web of power relations and antagonisms. Stone suggests that Marguerite Duras's semi-autobiographical novel The Lover (1984) provides a model of this understanding. Both in its content and its formal construction, the novel expresses a process whereby the daughter differentiates herself from her mother while remaining connected to her. It is an ongoing, unresolved and conflictual process in which the daughter never escapes the context of maternal body relations.


This article present the free vibration analysis of simply supported perfect and imperfect (porous) FG beams using a high order trigonometric deformation theory. It is assumed that the material properties of the porous beam vary across the thickness. Unlike other theories, the number of unknown is only three. This theory has a parabolic shear deformation distribution across the thickness. So it is useless to use the shear correction factors. The Hamilton;s principle will be used herein to determine the equations of motion. Since, the beams are simply supported the Navier\'s procedure will be retained. To show the precision of this model, several comparisons have been made between the present results and those of existing theories in the literature.


Background: Whereas the periodontal microbiota is well described, its non-bacterial component needs a better understanding. Metagenomic analyses show a strong increase of the protozoan Entamoeba gingivalis in inflamed periodontal pockets. Its presence is associated with periodontal deterioration and pockets typically 3mm or more in depth. The aim of this study is to observe the amoeba within the biofilm during active disease. Materials and Methods: Here, we present results of a phase contrast microscopy-based observation of amoebae in periodontal patients' subgingival plaque from infected sulcus. Plaque samples from deepest part of sulcus are picked up and spread out between blade and coverslip in patient saliva medium. We relate significant behavior of the parasite during active periodontal disease. Results: From low power observation, parasite is quite frequent. Once targeted, high power observation confirms amoeban anatomy and presence. We observed a high degree of amoeba locomotion and movements toward specific environments within the subgingival plaque. This was accompanied by the formation of "channels" within the biofilm. We also present evidence of adhesion to human cells as well as characteristically parasitic behavior. Specifically, we observed the intrusion of amoeba pseudopods into leukocytes coupled with a decrease in leukocyte intracellular granular activity. We documented both single trogocytic processes and trogocytosis through multiple pseudopods. In addition to leukocytes, we also observed trogocytosis of red blood cells. Parasitic behavior was also evident from the observation of amoebae digesting the nuclei of multiple vacuolar white blood cells, simultaneously. Following trogocytosis, polynuclear neutrophils had the appearance of ghost cells. Finally, we show evidence for amoeba nesting and reproduction within periodontal pockets. Conclusion: Phase contrast microscopy of periodontal biofilms strongly suggests that E. gingivalis escapes the first lines of innate defenses and promotes a pathological state. Trogocytosis and exonucleophagy processes targeting neutrophils could consequently disrupt neutrophil extracellular traps activity and normal apoptotic function, a vital component of wound healing. This study points to Entamoeba gingivalis as a microbe involved in the inflammatory process during periodontitis and as a driver of the disease rather than a harmless commensal species.


Motivated by iron-based superconductors, we develop a self-consistent electronic theory for the itinerant spin excitations in the regime of coexistence of the antiferromagnetic stripe order with wave vector ${\mathbf{Q}}_{1}=(\ensuremath{\pi},0)$ and ${s}^{+\ensuremath{-}}$ superconductivity. The onset of superconductivity leads to the appearance of a magnetic resonance near the wave vector ${\mathbf{Q}}_{2}=(0,\ensuremath{\pi})$, where magnetic order is absent. This resonance is isotropic in spin space, unlike the excitations near ${\mathbf{Q}}_{1}$, where the magnetic Goldstone mode resides. We discuss several features which can be observed experimentally.


In 1907, Franke and Roehl, working in Ehrlich's laboratory, recorded a very interesting observation (Ehrlich, 1907). They found that the feeding of nagana-infected mice with parafuchsin caused the disappearance of trypanosomes from the peripheral blood; after a week or two, however, the parasites reappeared, but further administration of the drug caused them to disappear again. The process could be repeated, but not indefinitely, as after a time it was noticed that the parafuchsin feeds began to produce less and less effect ; after each successive administration of the drug the time of banishment of the parasites from the blood of the mouse became shorter and shorter, until, finally, a period was reached when the drug entirely failed to influence the parasites. On transference of the parasites to normal mice they were found to be still uninfluenced by parafuchsin, and it became evident that they had in fact acquired a heightened resistance to the drug. This fundamental observation was quickly followed by the discovery that strains of trypanosomes resistant to other drugs could be developed. The practical significance of the capacity of trypanosomal infections to become drug-resistant, or drug-fast, for the treatment of the infections in man and stock was at once recognized by Ehrlich, and during the last twenty-five years the whole question, in its various aspects, has been the subject of an enormous literature and of a considerable amount of work. Nobody who attempts to orientate himself through the vast number of papers dealing with the subject of drug resistance call fail to be impressed with the many contradictory statements which have been made, with the unwarrantable and sweeping inferences which have been drawn from the most inadequate experimental data, and with the enormous superstructure of hypothesis which has been erected on a most insecure foundation of questionable facts. This is the more interesting because the clinician, having grasped the fact that there are such things as drug-fast strains of trypanosomes, has hastened to explain his failure to cure many of his cases of human trypanosomiasis on the hypothesis that the parasite has become arsenicor antimony-resistant. He has not paused to reflect that he has really obtained not the slightest evidence that the trypanosomes infecting his patient have actually developed resistance to the drug or drugs he has employed, or to ask himself whether there may not possibly be some other explanation for the failure of his treatment. As a matter of fact, although analogies suggest that drug resistance probably plays a very important part in the therapy of human trypanosomiasis, there is remarkably little direct evidence that drug-resistant strains do actually develop during the treatment of infected man. When we turn to other diseases such as malaria, syphilis, and leishmaniasis, we find similar explanations given of the failure to cure. Such statements are even less justifiable, as we have no satisfactory proof that Plasmodium sp. ever becomes resistant to quinine, or S. pallida to mercury and salvarsan, or Leishmania donovani to preparations of antimony. It is now about five years since my colleagues and I commenced a serious study of chemotherapy, and almost


Prediction of ship powering is traditionally based on the results of model experiments. This paper covers the extrapolation of model test results for ships that may have a multitude of appendages and one or more complex propulsors. The major differences from conventional extrapolation methods are the application of the scale effect corrections to the model propulsion test, the treatment of the appendages and acknowledging the effects of the propeller load on the propulsion parameters. The last feature is considered essential to successfully handle complex propulsors with both rotating and passive components.


A growing body of literature has emerged that demonstrates the potential of neurogaming platforms for interfacing with well-known video games. With the recent convergence of advances in consumer electronics, ubiquitous computing, and wearable sensor technologies real-time monitoring of neurocognitive and affective states can be studied in an objective, timely, and ecologically valid manner. Whilst establishing the optimal relation among frequency bands, task engagement, and arousal states is one of the main goals of neurogaming, a standardized method has yet to be established. Herein we aimed to test classifiers within the same context, group of participants, feature extraction methods, and protocol. Given the emphasis upon neurogaming, the commercial-grade Emotiv EPOC headset was used to collect electroencephalographic (EEG) signals from users as participants experienced various stimulus modalities aimed at assessing cognitive and affective processing. The EEG data were then filtered to get separate frequency bands to train cognitive-affective classifiers with three classification techniques: Support Vector Machines (SVM), Naive Bayes (NB), and kNearest Neighbors (kNN). Results revealed that the NB classifier was the most robust classifier for identifying game-based Death Events. However, the identification of General Gameplay Events is best identified using kNN and the Beta band. From this study's findings, it is suggested that using a combination of classifiers is preferable over selecting just one classifier.


This paper presents work on an artificial anthropomorphic agent with multimodal interaction abilitities. It focuses on the development of a markup language, MURML, that bridges between the planning and the animation tasks in the production of multimodal utterances. This hierarchically structured notation provides flexible means of describing gestures in a form-based way and of explicitly experessing their relations to accompanying speech.


Production control, planning, and scheduling are forms of decision making, which play a crucial role in manufacturing industries. In the current competitive environment, effective decision-making has become a necessity for survival in the marketplace. This chapter provides insight into the issues relating to integration of fuzzy logic techniques into decision support systems for profitability quantification in a manufacturing environment. The chapter is divided into five sections with a general introduction of the topic, followed by a thorough literature review on the existing techniques. Thereafter, fuzzy logic algorithms using logistic membership functions and resource variables for decision making aiming at quality improvement are discussed. A case study involving a textile firm is then described with the computational results and findings, and finally, future research directions are presented.


Why refer to licitations and administrative contracts when focus the theme of concessions and permissions of public services? The fact is that the 1988 Constitution, differently from the previous ones, has stated, in article 175 that is a task of Public, directly or under the rule of concession or permission, but always through licitation, the operation of such services, being in form of the law (it's private competence of the Union to legislate about general rules on licitation and administrative contracts) will the rules of concessionaires and permissionaires of public services be disciplined (we're not mentioning either concessions or permissions to use public properties), the feature of contract, etc., including the user's rights, the fare politics and the obligation to keep appropriate service. Sao Paulo State had already disciplined the issue through Law 7.835/92, including rules about licitation and even its exceptions, stating that this licitation must be the concurrency, and determining (article 3, sole §, that the Public Power, act of his own, or by delegation, would publish the definition of object, area of operation, time terms and directions to be observed in the concurrency "Edital" (this was repeated by the federal Law 8.987/95, article 5th). That's why in the recent governmental decision of concession of the Anhaguera/Bandeirantes system, were published the Decree 40.077, 10.05.95, and the Transport Secretary Resolution n. 16, in the following day. Such comments about licitation are enough, by now, but it's worth stating that by confronting the State law the Federal law, was prevailed what in opposite has been stated on the latter. For example, the Federal law does not foresee cases of licitation exceptions, issue that certainly constitutes "general" rule, of Union competence (art. 22, XXVII, Federal Constitution). But the questions that might be misunderstood, refer more specifically to the contracts of concession, and, after that Federal law, the permission contracts as well. My desire, here, is not to teach what is an administrative contract, but provide that a debate could arise, in order to get to a conclusion on the imperfections and the necessity or not of changes on Federal law, or interpretations that could make the application of the law possible.


This paper examines the state of small-scale business under the modern conditions of the economy of the country. Both the main promising trends of small-scale enterprise activity and significances of these trends as a basis of stabilization and development of the State economy at the current stage are defined. It is corroborated that focus on innovations and increase in quantity of small-scale enterprises themselves will make a major contribution to development of the new innovative economy in whole. It should be also noted that the partnership between state-run organizations and private business, outsourcing, government order, and creation of science intensive enterprises under institutes of higher education are of great importance when a entrepreneur choices a kind of activity.

This paper aims to find out future tasks of GICOMS(General Information Center on Maritime Safety & Security) through identification of required system for implementation of e-Navigation. We derive nine advancement subjects for model of advanced GICOMS through brainstorming with experts of maritime safety. And then, we analyze the structure of extracted nine advancement subjects using by fuzzy structural modeling method, and propose a structural model that grasps the correlation between elements. As a result, we find out that "advancement of GICOMS" is the final goal in preparation for the age of e-navigation in the highest level, and "improvement a system of information production", "improvement a scheme of information providing", "linkage between GICOMS and VTS" and "building global networks for safety cooperation" are located in the lowest level. Especially, "advancement of GICOMS" is influenced by "advancement function of VMS" and "Activation of usage" in the middle level. We suggest that state-of-the-art IT facilities, equipment and expertise should be utilized to improve and enhance the user-centered transition such as maritime workers for advancement of GICOMS based on proposed structure model.


This paper is a discussion on the computation of child support and marital support payments. The Japanese Family Court has been engaged in efforts to simplify the method for determining support amounts in divorce and separation cases, and to provide rate schedules to streamline the process. The purpose for establishing a child support schedule is to facilitate the computation of child support in a manner that ensures a level of support that is both appropriate and adequate for maintaining a child's standard of living. The schedule for marital support serves as the basis for computing payments to a spouse in cases of separation in a manner that ensures a level of support that is adequate for maintaining the spouse's standard of living.


The Southern California Edison Company (SCE) initiated a precipitation chemistry sampling network in the fall of 1979 that has continued in operation to the present. Multi-stage, wet-only, event samples are collected at a number of locations in Southern California and analyzed for the following species: acidity (pH), SO{sub 4}{sup 2{minus}}, NO{sub 3}{sup {minus}}, Ca{sup 2+}, Mg{sup 2+}, Na{sup +}, K{sup +}, NH{sub 4}{sup +}, Cl{sup {minus}}, F{sup {minus}}, PO{sub 4}{sup 3{minus}}, Br{sup {minus}}, metal ions, and conductivity.

The ultrasonographic diagnosis of urethral obstruction in a fetus is made by demonstrating bi-lateral hydroureteronephrosis plus a large, thick-walled bladder that does not empty well.' We report a case of bilateral hydronephrosis with'an unchanging bladder volume over 8 h, leading to the presumptive diagnosis of posterior urethral valves. Postnatal diagnostic studies revealed that the infant had bilateral duplex collecting systems with massive reflw into the lower moieties.


Abstract We study the time-evolution of the magnetization in the metallic glass Fe83 B12 Si5 on different isotherms (634 K ≤ T ≤ 666 K) and at different magnetic fields (300e ≤ H ≤ 10k Oe). The magnetization increases with time owing to the growth of a magnetic crystalline phase. The growth rate increases with increase of either temperature or magnetic field.


Abstract A UPLC–MS/MS method was developed and validated the determination and pharmacokinetic study of magnoflorine, cauloside C, hederagenin, and oleanolic acid from Caulophyllum robustum. Digoxin was used as the internal standard. The pretreated plasma samples were carried out on a Waters ACQUITYUPLC HSS T3 column at 35 °C with a mobile phase of acetonitrile–water (90:10, v/v) at a flow rate of 0.2 mL/min. This article describes the most simple, sensitive, and validated UPLC–MS/MS method to date for the simultaneous successful determination of four compounds in rat plasma after oral administration of the extract of C. robustum and their pharmacokinetic studies.

Design research and the literature on sociomateriality emerge out of different academic traditions but share a common interest in the material. A sociomaterial perspective allows us to account for the complex ways people mingle and mangle information systems of all sorts into their social endeavors to accomplish organizational tasks. But, how do we account for these sociomaterial phenomena in all their complexity when faced with the task of designing information systems? The panel brings together prominent researchers bridging the gap between design research and the current debate on sociomateriality. Each presenter addresses the challenges associated with informing grounded design work with insights from a highly abstract intellectual debate.


The Internet of Things (IoT) is one of the emerging technology in today's world to connect billions of electronic devices and providing the data security to these electronic devices while transmission from the attacks is a big challenging task. These electronic devices are smaller and consume less power. The conventional security algorithms are complex with its computations and not suitable for IoT environments. In this article, the hardware architecture of the new Lightweight encryption algorithm (LEA) for the secured Internet of things (SIoT) is designed, which includes Encryption, decryption along with key generation process. The New LEA-SIoT is a hybrid combination of the Feistel networks and Substitution-permutation Network (SPN). The encryption/decryption architecture is the composition of Logical operations, substitution transformations, and swapping. The encryption/decryption process is designed for 64-bit data input and 64-bit key inputs. The key generation process is designed with the help of KHAZAD block cipher algorithm. The encryption and key generation process are executing in parallel with pipelined architecture with five rounds to improve the hardware and computational complexity in IoT systems. TheLEA-SIoT is designed on the Xilinx platform and implemented on Artix-7 FPGA. The hardware constraints like area, power, and timing utilization are summarized. The Comparison of the LEA-SIoT with similar security algorithms is tabulated with improvements.


Vaginal herpes infections occur under low oxygen conditions, including anoxia. Using an anaerobic (0% O2) cell system, the infection rate, early protein expression, and progeny viability were determined. Anaerobic HeLa 229 cells (0% O2; anaerobic DMEM; 24h) were infected with MOI 1 of HSV1/2, then incubated under aerobic (control) and anaerobic conditions. Infectivity (6h post-infection (pi)) was assessed by ONPG activity and enumerating X-gal-stained cells. HSV1/2 viral immediate-early entry, early entry, and late entry protein expression were determined by fluorescent antibody staining followed by HSV1/2 glycoprotein B mouse monoclonal antibody and DAPI. Statistical analysis was performed using t-test and data were considered significant when p ≤ 0.05 (GraphPad Prism). HSV1/2 infection under standard aerobic conditions was approximately twice that measured for anaerobically infected cells. In addition, the level of HSV-2 infectivity was significantly (p < 0.05) higher (~8-fold) than that of HSV-1, regardless of oxygen level. HSV entry stage protein expression (ICP8, ICP27, VP5) was detected for anaerobic HSV1/2. A similar pattern was observed for anaerobically grown progeny of HSV1/2, i.e., the number of progeny was higher when anaerobic progenies were grown under aerobic conditions (anaerobic to aerobic) as compared to those grown under anaerobic conditions (anaerobic to anaerobic). In addition, the progeny levels grown solely under anaerobic conditions trended higher for HSV-1 than HSV-2 progeny but were not significantly different. These findings show that HSV1/2 can infect and replicate in anaerobically growing cells and that oxygen is not essential for productive replication.


Abstract : An analysis is made of the major goals in solid rocket propulsion development. These include high-specific impulse propellants and high propellant loading fraction.


We applied the transmission/disequilibrium test (TDT) for sibs (S‐TDT) and for families with one parent (1‐TDT), to the Collaborative Study on the Genetics of Alcoholism data set. The combined test is used to screen the whole genome to locate genes responsible for alcohol dependence. This analysis supports the previous finding that the region close to GABRB1 on chromosome 4 might be associated with alcohol dependence. The regions close to D6S474 and D11S1998 are also of particular interest. We found segregation distortion at the GR1K1 locus. The segregation distortion might be due to the binning method used in genotyping at this locus.


Continuous directed evolution techniques leverage error-prone replication machinery for rapid in vivo mutagenesis of target genes. However, promiscuous activity by error-prone machinery can lead to damage of the host genome. Here, we propose an orthogonal replication system, DiversiPhi29, for the continuous directed evolution of genes in vivo in a bacterial chassis. This system leverages the well-studied bacteriophage ɸ29 and E. coli . In this project, we first attempt to modify four ɸ29 proteins to enable the heterologous replication of a linear construct consisting of a single gene-of-interest and origin sequences. Once orthogonal replication is established, we will implement a system capable of tuning the mutation rate of the linear construct's replication by altering the ratio of two ɸ29 DNA polymerases, one of which contains fidelity-reducing mutations. This approach will enable high throughput molecular evolution in the best understood model organism.


The authors describe a computer program in which students define alternative policy sets and compare their effects on the welfare of producers, consumers, and the public sector. A policy set may be a single tax or quota or a mix of taxes, subsidies, quotas, and/or price supports implemented at various points in the marketing chain.


Our patients do not want scars. Even when all goes well and a surgical procedure produces an "acceptable" scar, there are quality of life measures that decline significantly as a result of the physical and psychological impact of having a scar. Problems can occur in any of the 3 stages of wound healing (inflammation phase, proliferation phase, or remodeling phase) and when a hypertrophic or keloidal scar is formed, the situation becomes even worse. Minimizing scars from our surgical procedures and those produced by other forms of trauma or disease weighs heavily on dermatologists. Good surgical technique and proper wound care go a long way in minimizing the risk of abnormal scar formation. Topical treatments, injectables, lasers, other energy sources, and physical modalities such as subcision, microneedling, and dermabrasion have all been used to improve the appearance of scars. This issue examines how normal and abnormal scars form and presents a wide variety of treatment options available today to treat scars. Drs. Berman, Maderal, and Raphael review the pathophysiology, classification, and treatment of hypertrophic and keloidal scars. They describe how the ratio of various subtypes of interleukins and growth factors play an important role in the formation of scars and howa small imbalance can have dramatic effects. They go on to present a comprehensive overview of the various treatment options available for hypertrophic andkeloidal scars anddiscuss themechanismof action of each. Drs. Cohen, Geronemus, McDaniel, and Brauer performed a literature reviewon the role elastin fibers play in scar formation and discuss how laser treatments help normalize the disorganization of the elastin fibers typically found in scars. In another article in this issue, Dr. Yang compares the gene expression of hypertrophic scar markers after being injected with a steroid, a calcium channel blocker (verapamil), and interferon.


The behavior of building during Earthquake depends critically on its overall shape, size and geometry. The Seismic performance of building is available and new design methods should account for the building ability to dissipate energy and the effect of the lateral deformation. These aspects involve both plan and structural configuration of building. This paper presents structural and seismic behavior of buildings. The purpose is to outline the criteria loading on structure of building during strong earthquake. Building are the complex system and multiple configuration have to be considered at the moment of designing them. That's why at the planning stage of building, architects and structural Engineers must work together to ensure that the unfavorable features are avoided and good configuration is chosen. The principle objective of this project is to analysis and design a multistoried building (G + 21 (3 dimensional frame)) using STAAD Pro. The design involves load calculations manually and analyzing the whole structure by STAAD Pro. The design methods used in STAAD-Pro analysis are Limit State Design conforming to Indian Standard Code of Practice. We considered a 3-D RCC frame with the dimensions of 4 bays @5m in x-axis and 3 bays @5m in z-axis. The y-axis consisted of G + 21 floors.


Abstract Based on point of view of Ma Yun, the era of pure e-commerce will soon end, and the future will not have e-commerce but "New Retail", which means enterprises must meet customer needs, and have efficient functions to integrate online, offline and logistics. Therefore, this study attempts to establish an integrated architecture, from the consumer point of view to explore the external market-oriented consumer technology acceptance model, and explores the impact of external market orientation on perceived usefulness, perceived ease of use, use attitude and behavioral intentions. The theoretical structure was validated by structural equation modeling (SEM) using AMOS software, and 315 valid samples were used for empirical analysis. Empirical results show that external market orientation positively affects perceived usefulness and perceived ease of use of consumers; perceived usefulness positively affects attitudes; perceived ease of use positively affects use attitudes; uses attitudes positively affect behavioral intentions; however, perceived usefulness cannot directly affect the behavioral intentions, so perceived usefulness can influence the behavioral intentions by enhancing the use attitude of consumers. In addition, the use attitude for perceived usefulness affects the important mediator variables of the behavioral intentions. Finally, according to the research, this paper puts forward the suggestion of management meaning and the academic future reference to the research of "New Retail".


Lots of researches have been done on Yin Fan and his The Collection of He Yue Ying Ling by the senior scholars. Based on these researches and starting with the forms of the selected poems,the content characteristics of the emotion in the poems and the official ranks of selected poets,this paper examines Yin Fan's poem-selecting mentalities in compiling The Collection of He Yue Ying Ling and concludes that Yin Fan's works,firstly displays his past-respecting mentality,secondly reveals his depression caused by the failure in realizing his lofty aspirations and his yearning for the easy and secluded life,and thirdly reflects his determination to compile works because of his genius unrecognized. Influenced by all these mentalities,The Collection of He Yue Ying Ling has become a book of some critical value and strong individual characters.


OBJECTIVES/GOALS: The primary objective of this study is to evaluate the risk of an early syphilis diagnosis following a chlamydia, gonorrhea, or HIV diagnosis, and to determine differences by race, repeat infection, diagnosing provider and STI/HIV risk behavior among cisgender women in Baltimore, MD. METHODS/STUDY POPULATION: Public health surveillance data from 2009-2021 was used to examine the overall incidence of syphilis infections among cisgender women ages 13-50 diagnosed with a reportable STI (chlamydia, gonorrhea, or HIV) and the percentage of total infections that were early infections (primary, secondary, or early latent syphilis) in Baltimore City. Data were collected on age, race, diagnosing location (i.e., STI clinic, private provider, etc.), preceding STI diagnoses, and sexual risk behaviors. STI-specific cumulative incidence and incidence rate ratios were used to compare syphilis diagnoses among Black vs. white women, women with repeat STI diagnoses vs. one STI diagnosis, women diagnosed at a public vs. private clinic, and commercial sex workers and substance users vs. those not reporting these risk behaviors. RESULTS/ANTICIPATED RESULTS: Based on recent surveillance data, we expect approximately 79,000 chlamydia, gonorrhea, and HIV diagnoses among cisgender women between 2009-2021. We hypothesize that 3% of chlamydia, gonorrhea, and HIV diagnoses among cisgender women will be followed by a syphilis diagnosis within the study period. Extrapolating from previous studies of early syphilis in men who have sex with men in Baltimore, we expect the rate of syphilis diagnosis following STI diagnosis will be higher in Black vs. white women, women with a prior gonorrhea or HIV diagnosis vs. chlamydia diagnosis, women with repeat STI diagnoses vs. one STI diagnosis, women diagnosed at public STI clinics vs. those diagnosed by private providers, and women reporting commercial sex work and/or substance use vs. those not reporting these risk behaviors. DISCUSSION/SIGNIFICANCE: Local healthcare providers should offer syphilis screening to any woman diagnosed with a chlamydia, gonorrhea, or HIV infection. The higher rates of early syphilis diagnosis among women with repeat STI diagnoses or a prior gonorrhea or HIV diagnosis suggests regular screening is critical in these populations.


In this paper, we study the divisibility of the function a(n) defined by $\sum_{n\geq 0} a(n) q^n := (q;q)^{-1}_\infty (q^2; q^2)^{-1}_\infty $. In particular, we prove certain "Ramanujan type cong...


As a form of communication that evokes laughter, humor is seen as one of important aspects in building relationship with people. Linguists suggest that humor exists because there is noncooperative interaction among interlocutors resulting from not observing Cooperative Principle in the conversations. Related to that, this study aims to analyze humorous situations in a situation comedy entitled How I Met Your Mother Season 2, Episodes 1 to 5 which are created by violating and flouting the conversational maxims as the forms of not observing the Cooperative Principle. Keywords: humorous situation, cooperative principle, flouting, violation


In this paper we focused on investigating how the sphere of musical amateurism functioned in Yugoslavia in the decades following the end of WWII. Observing through changes in the role and significance of amateur music ensembles, specifically choirs, in Yugoslav society from the late 1940s until the late 1960s / early 1970s that were manifest in their de-massification, gradual professionalisation and extensive use in cultural diplomacy, we sought to explain that this involved multiple factors – above all, the shifts in Yugoslav international policy after the confrontation with the Soviet Union in 1948, and, consequently, the revisions of its cultural policies. Their influence was observed through a detailed examination of the activities of the Beogradski madrigalisti choir, from its foundation in 1951 until the late 1960s / early 1970s. Although it was unique among Yugoslav choirs in many respects, the early history of this ensemble clearly reflected the demand for excellence in the sphere of amateur performance from the 1950s onwards, one of the most prominent indicators of its deep structural transformation.


The 370-mile shallow-draft waterway that extends from the ports of Portland, Oregon and Vancouver, Washington upstream to Lewiston, Idaho is the largest artery for waterborne commerce in the Pacific Northwest, and a critical link connecting inland grain producing areas with ocean-going transportation. Since it makes up the main stems of the Snake and Columbia Rivers, it is also subject to water issues inherent in a large, multiple-purpose river system, including electrical energy production, flood control, irrigation, and the maintenance of instream flows for fishery migration. In most years, these management objectives co-exist with navigational requirements with relatively little conflict. In low runoff years, however, competition for water uses can be critical and sensitive, reaching high levels of attention within the institutional and political arena in the Pacific Northwest.


After thirty years of work on computer security, why are almost all the systems in service today extremely vulnerable to attack? The main reason is that security is expensive to set up and a nuisance to run, so people judge from experience how little of it they can get away with. Since there's been little damage, people decide that they don't need much security. In addition, setting it up is so complicated that it's hardly ever done right. While we await a catastrophe, simpler setup is the most important step toward better security. In a distributed system with no central management like the Internet, security requires a clear story about who is trusted for each step in establishing it, and why. The basic tool for telling this story is the " speaks for " relation between principals that describes how authority is delegated, that is, who trusts whom. The idea is simple, and it explains what's going on in any system I know. The many different ways of encoding this relation often make it hard to see the underlying order.


We argue that a quantum aether is consistent with the principle of relativity and can provide an economical way of having an invariant quantum gravity or Planck scale. We also show that it may change the effective scale at which quantum gravity effects may be observable.


The impacts of the electromagnetic effects on resistive and collisionless drift waves are studied. A local linear analysis on an electromagnetic drift-kinetic equation with Bhatnagar-Gross-Krook-like collision operator demonstrates that the model is valid for describing linear growth rates of drift wave instabilities in a wide range of plasma parameters showing convergence to reference models for limiting cases. The wave-particle interactions drive collisionless drift-Alfven wave instability in low collisionality and high beta plasma regime. The Landau resonance effects not only excite collisionless drift wave modes but also suppress high frequency electron inertia modes observed from an electromagnetic fluid model in collisionless and low beta regime. Considering ion temperature effects, it is found that the impact of finite Larmor radius effects significantly reduces the growth rate of the drift-Alfven wave instability with synergistic effects of high beta stabilization and Landau resonance.


We have investigated the electronic band structure of hydrogen and oxygen adsorbed single and double layer stepped Si(100) surfaces by Empirical Tight Binding (ETB) method. The total electronic energies of the H,O-SA, DA, DB type stepped Si(100) systems are calculated with limited number of hydrogen and oxygen atoms separately to find out the most probable adsorption sites of the adatoms in the initial stage of hydrogenation and oxidation.


Amorphophallus paeoniifolius (Dennsteadt) Nicolson (elephant foot yam) plants were collected from different regions in Java to analyze the diversity of morphological and nutritional characteristics among accessions. Principal component analysis of nine morphological characteristics showed that 74% of total variations could be explained by the first four components. Scatter diagrams of the first and second components showed that 32 accessions could be classified into five groups, A to E. A comparison of growth habitats among these groups revealed the fact that most of the plants in groups A, B, and E were collected from lowland areas while most of the plants in group C were sampled in upland regions. Plants in group D did not show any distinct characteristics in terms of growth habitat. Using cluster analysis, the 32 accessions were divided into three groups, I, II, and III. Cluster I consisted of groups B, D, E, and two of the nine accessions in group C. On the other hand, cluster II corresponded to group A, and cluster III corresponded to the remaining seven accessions in group C. Starch concentrations in the corms ranged from 36 to 114 mg g-1 fresh matter, while the sucrose concentrations ranged from 0 to 2.3 mg g-1 fresh matter. It is unlikely that the carbohydrate concentration was related to the classification based on morphological characteristics.


Andrew Lefevere and Hans Vermeer' are outstanding figures in the history of translation studies.Their theory Rewriting and Skopostheory can be considered as milestone in their study history.This paper makes comparison between two theories with regard to their main features and makes persons-in-the-translation further get a deeper understanding of two theories.


The ultimate objective of this study was to identify and develop future opportunities and initiatives for the reduction and recovery of wastes generated by the food processing and foodservice sectors in the state. The food processing sector, as defined in the Standard Industrial Classification (SIC) system, represents a major portion of Georgia's industrial base, and in 1995 employed 58,700 workers, with total payrolls of $1.42 billion, and consumed $9.41 billion of raw materials to produce $16.21 billion of manufactured goods, with $6.80 billion of value added (U.S. Bureau of the Census, 1998). With respect to institutional food waste generators, restaurants employed 253,800 statewide, 139,700 of them in the Atlanta Metropolitan Service Area (Georgia Department of Labor, 2000). Other establishments considered potential generators of institutional food waste include retail food stores, educational institutions, healthcare establishments, correctional institutions, and hotels and lodgings. The potential for waste generation in the food processing and institutional food sectors, given their considerable size and broad scope, was thought to be substantial, hence the development of alternatives and opportunities for the reduction and recovery of these wastes was expected to have major impacts, not only in preserving solid waste disposal (i.e., landfill) capacity, but potentially in the economical operation of these industries as well.


The aim of the master thesis is to investigate ground movements due to pile installation at the Gamlestadstorget construction project and to compare different methods used for analysis and prediction. The thesis was conducted through a literature study, a case study of a part of Gamlestadstorget Spårskede 4, and a FE-modelling with the numerical tool PLAXIS 2D. The scope was to investigate section 100/130, with regard to horizontaland vertical displacements caused by the installation of hammered pre-cast concrete piles and bored steel pipe piles. For the FE-modelling, a reference project of the Partihall highway bridge was investigated to identify a suitable pile modelling method. With the use of volumetric expansion, to simulate the total installed pile volume, together with a 50 per cent pre-auger efficiency, it was possible to achieve good agreement compared to measured data. From the results of the section 100/130 model, it was possible to conclude that a volumetric expansion equal to 50 per cent of the installed pile volume, together with a 50 per cent pre-auger, complied best with measured data. In the comparison with the empirical method by Rehnman and the semianalytical method by Sageseta, PLAXIS had the best agreement to measured data with depth. It can also be concluded that it is possible to model the soil displacements from a pile group installation in a plane strain model. However, due to several insecurities in the case study, a general advice cannot be established until the method have been verified in several other cases. The movement caused by the bored steel pipe piles was irrelevant and thus determined as being infeasible to model in the scope of this thesis. Future research could be to study the installation effects of bored steel pipe piles by more extensive measurements or further studies to validate the pile modelling in PLAXIS.


Abstract The literature suggests that individuals will be healthier if they live in Active Community Environments that promote exercise and activity. Two key elements of such environments are walkability and safety. Examining data from the National Health and Nutrition Examination Survey III, 1988-1994 and using a multilevel analysis, we found that individuals who live in counties that are more walkable and have lower crime rates tended to walk more and to have lower body mass indices (BMIs) than people in less walk-able and more crime-prone areas, even after controlling for a variety of individual variables related to health. Among lifelong residents of an area, lesser walk-ability and more crime were also associated with respondents reporting weight-related chronic illness and lower ratings of their own health. The effect of high crime rates was substantially stronger for women than for men, and taking this interaction into account eliminated gender differences in walking, BMI, weight-related chronic conditions, and self-reported poor health. The results suggest that to promote activity and health, planners should consider community walkability, crime prevention, and safety.


This paper describes a local project that involves a battery energy storage system (BESS) for the purpose of aiding peak shaving on a feeder that will soon have a significant level of PV Penetration. Additional applications of the BESS that are compatible with peak shaving are considered, along with numerous incidental benefits that emerge from such an installation, in an effort to justify the high cost of this asset.


Recent studies have shown the spasmolytic activity of p-menthane monoterpenes (+)-pulegone and 4-terpinyl acetate (4-T) in guinea pig ileum. Since the action mechanism of these monoterpenes in intestinal smooth muscle is unknown, the present study was conducted to characterize their relaxant mechanism in isolated guinea pig ileum. We tested the involvement of voltage-dependent calcium and potassium channels and muscarinic antagonism. Both the monoterpenes caused a shift in the calcium curve to the right with reduction in the maximum effect. Pretreatment with tetraethylammonium chloride partially inhibited relaxation produced by both 4-T and (+)-pulegone. Both compounds caused a shift in the bethanechol curve to the right with reduction in the maximum effect. The results of this study indicate that the mechanisms of action of the smooth muscle relaxant monoterpenes (+)-pulegone and 4-T possibly involve the partial blockade of calcium channels, the activation of potassium channels, and the non-competitive antagonism of muscarinic receptors.

The genus Cestradoretus Ohaus, 1912 was erected by Ohaus (1912) to accommodate a Madagascan Adoretini species, C. tenuirostris Ohaus, 1912. This genus is characterized by the adults having the apex of the labrum with a long, fine, acute process curved downwards. In the addition to the above mentioned paper, Ohaus (1912) also described C. acomys Ohaus, 1912 from Tanzania, and later moved Adoretus tarsatus Klug, 1855, described from Mozambique, to Cestradoretus (Ohaus 1916).  Later, Machatschke (1965) described two species from Africa, C. freyi Machatschke, 1965 from Botswana and C. minusculus Machatschke, 1965 from Somalia, and Frey (1976) described C. clypealis Frey, 1976 from Somalia. Thus, Cestradoretus included six species, one from Madagascar and five from Africa.

This research examined the pedestrian accidents in Khon Kaen Municipality, Thailand. The data used to analyze the pedestrian accidents were obtained from Khon Kaen Regional Hospital. Initially, to determine the contributing factors of pedestrian accidents, the category analysis of data involving pedestrian accidents were conducted by using the chi- square test. Afterwards, the SPSS program was employed to develop the pedestrian prediction crash models. A step-wise analysis was performed on several selected contributing factors of pedestrian accidents. To identify locations where pedestrian crash problems exist in Khon Kaen Municipality, the ArcView GIS spatial was employed to create the pedestrian crash density map. The pedestrian unsafe conditions were also investigated through the concept of road safety audit at the identified high pedestrian crash locations. Finally, recommendations to improve these unsafe conditions were suggested.

A Holographic Versatile Disc (HVD) system, using Collinear Technologies for a high capacity and high data transfer rates storage system, is proposed. With its unique configuration the optical pickup can be designed as small as a DVD's, and can be placed on one side of the disc. With the HVD's special structure, the system can servo the focus/track and locate reading/writing address. A unique selectable capacity recording format of HVD and its standardization activity are also introduced. Experimental and theoretical studies suggest that the tilt, wavelength, defocus and de-track margins are wide enough to miniaturize the HVD system at a low cost. HVD systems using Collinear Technologies will be compatible with existing disc storage systems, like CD and DVD, and will enable us to expand its applications into other optical information storage systems.

An analysis of the frequency of H63D (c.187C>G) mutations in the HFE gene in 19 populations from Central Eurasia demonstrated that the distribution of the mutation in the region of interest was not uni form and that there were the areas of H63D accumulation. The investigation of three polymorphic variants, c.340+4T>C (rs2071303, IVS2(+4)T>C), c.893–44T>C (rs1800708, IVS4(–44)T>C), and c.1007–47G>A (rs1572982, IVS5(–47)A>G), in the HFE gene in individuals homozygous for H63D mutations in the HFE gene revealed the linkage of H63D with three haplotypes, *CTA, *TTG, and *TTA. These findings indicated the partial spread of the mutation in Central Eurasia from Western Europe, as well as the possible repeated appearance of the mutation on the territory on interest.

We shortly review the progress in the domain of deterministic chaos for quantum dynamical systems. With the appropriately extended definition of quantum Lyapunov exponent we analyze various quantum dynamical maps. It is argued that, within Quantum Mechanics, irregular evolution for properly chosen observables can coexist with regular and predictable evolution of states.


We introduce the category of finite Chow-Witt correspondences over a perfect field k with char(k) 6 2. We then define for any essentially smooth scheme X and integers p;q 2 Z generalized motivic cohomology groups H p;q (X; ~ Z). We finally prove that H n;n (Spec(L); ~ Z) = K MW (L) for any finitely generated field extension L=k and any n 2 Z.


The busy period, busy cycle, and the numbers of customers served and lost therein, of the G/M/m queue with balking is studied via the embedded Markov chain approach. It is shown that the expectations of the two discrete variables give the loss probability. For the special case G/M/1/N a closed expression in terms of contour integrals is obtained for the Laplace transform of these four variables. This yields as a byproduct the LIFO waiting time distribution for the G/M/m/N queue. The waiting time under random order service for this queue is also studied.


The purpose of the current study is to predict the difficulty (equated delta) of a large sample (n=21.3) of TOEFL reading comprehension items. (Only main idea, inference, and supporting statement items were sampled.) A related purpose was to examine whether text and text-related variables play a significant role in predicting item difficulty; we argued that evidence favoring construct validity would require significant contributions from these particular predictor variables. In addition, details of item predictability were explored by evaluating two hypotheses: (1) that multiple-choice reading comprehension tests are sensitive to many sentential and discourse variables found to influence comprehension processes in the experimental literature, and (2) that many of the variables identified in the first hypothesis contribute significant independent variance in predicting item difficulty.

The great majority of sentential and discourse variables identified in our review of the experimental literature were found to be significantly related to item difficulty within TOEFL's multiple-choice format. Furthermore, contrary to predictions which we attributed to critics of multiple-choice tests, the pattern of correlational results showed that there is a significant relationship between item difficulty and the text and text-related variables. We took this as evidence supporting our claim that multiple–choice reading items yield construct valid measures of comprehension. That is, since critics have pointed out that reading items can often be correctly answered without reading of the text passage, this seems to imply that item variables (not text nor text-related variables) should fbe prominent predictors of reading item difficulty. Since the contrary relationship was found, we concluded that this provides evidence favoring construct validity. We found, further, in several stepwise linear regression analyses, that many of these text and taxt-related variables provide independent contributions in predicting reading item difficulty. This was interpreted as providing additional support for construct validity.

More specifically, apart from the correlational results, the following stepwise linear regressions results were obtained.

For the full sample of 213 items, and where equated delta (an index of item difficulty) is the dependent variable, we found 33 percent (p < .0001) of the variance of item difficulty could be accounted for by sight variables. All sight variables reflected significant and independent contributions due solely to text and text/item overlap variables. This result provided evidence favoring constract validity of the TOEFL reading comprehension items. We also conducted a separate analysis of a subset (n=98) of the full set of 213 items to examine the possible statistical effect of nesting in the original sample, (Nesting occurs when several items relating to the same passage are analysed together; a non-nested subset is formed when only one item per passage is used.) Eleven variables accounted for 58 percent. (p < .0001) of the variance of this non-nested sample. Ten of these 11 variables reflected significant and independent contribution of text and text/item overlap variables. Eencs this subanalysis provided further support for construct validity. While both analyses provide evidence favoring construct validity of the TOEFL reading items, the differences in amount of variance accounted for suggests that nesting affects should be a concern in future studies predicting item difficulty.


Shallow biogenic gas has long known as a drilling hazard in petroleum industry which responsible for several blowouts in the past time. Despite its infamous name in the industry, biogenic gas usually composed of more than 95% methane and it contains considerable amount of global reserve to be produced in a relatively shallow area. In order to turn biogenic gas into a production horizon, different treatments are needed. This research took place in Bentu PSC, Talangjimar Field, and Tunu Field which are distributed in Central Sumatra Basin, South Sumatra Basin, and Kutai Basin respectively. By integrating AVO analysis (geophysics), burial history and geothermal gradient (geology), as well as carbon isotope and gas composition (geochemistry), one can easily detect the presence of biogenic gas in the subsurface area along with its origin and quality. Our investigation suggested that by combining the three geosciences elements, the chance of exploration success may increase significantly, leading to the addition of biogenic gas reserve to be produced in the future.


### What does "allosteric" mean?

In the context of receptors, the word allosteric is now widely used. It is, perhaps, not helpful for clarity of thought that different authors often use it to mean somewhat different things ([Colquhoun, 1998][1]).

At one extreme, the term "allosteric

The carrier-mediated transport of europium through a supported liquid membrane by immobilizing PC-88A (EHPNA) and Versatic 10 on a porous support has been investigated in order to explore its efficiency, effectiveness and utility. Europium from the source solution was transported in the pH range from 1 to 5.75 for EHPNA and 3 to 5.75 for Versatic 10 through a cellulose triacetate membrane towards a receiving solution of pH <2. However, the change in the europium concentration in the source solution with respect to time ( t ) was observed based on the expression. The observed permeability coefficient ( P ) increased along with an increase in the carrier concentration for both the EHPNA and Versatic 10 systems in the concentration ranges studied, 1.8 × 10^−5 to 1.8 × 10^−2 M (mol dm^−3) and 1.8 × 10^−5 to 4 × 10^−2 M respectively. Above this range it remained nearly constant. The effect of complexation with citric, succinic and malonic acids on the permeability has been explored. The enrichment factor (EF) has also been evaluated.


Some time ago, we developed a formalism for the statistical thermodynamics of systems in thermodynamic equilibrium (1). Although it is closely related to traditional methods, the precise nature of this relation at first appeared obscure. The difficulty can be traced to an ambiguity in the use of ensembles in statistical mechanics, connected with the incomplete separation of two logical structures in the theory. It is, of course, well known that classical statistical mechanics can be developed from both the Boltzmann and the Gibbs points of view. However, the two lines of thought have never been completely disentangled, nor is it obvious what the distinctive features are that ought to be emphasized. The following analysis is felt to be useful in clarifying the concept of statistical ensembles. In the Boltzmann scheme, a small subsystem of a large isolated system is described by a canonical distribution function. The large isolated system can be assumed to exist in many identical samples, and these may be said to form a microcanonical ensemble. In the Gibbs scheme, one considers a finite system interacting with an infinite reservoir of definite temperature. The canonical, or temperature, ensemble is now defined as a set of systems interacting with the reservoir of given temperature and exhibiting a random distribution of the energy. The microcanonical, or energy, ensemble consists of systems within a narrow range of energy u < U < u+du, and is a subset of a canonical ensemble. The microcanonical ensemble has no definite temperature because we cannot ascertain the temperature of the reservoir with which it was last in contact. Even though the Gibbsian ideas have been widely used, they have not been developed as a self-contained logical structure. In particular, Gibbs postulated the canonical ensemble merely on the basis of plausibility. This gap in the theory was filled by the use of considerations that belong to the Boltzmann context. In fact, the use of Liouville's theorem for establishing a priori probabilities seemed to require the use of an isolated microcanonical system as a point of departure. The autonomous development of the Gibbsian concept of ensembles is possible if use is made of some of the techniques of mathematical statistics, such as the theory of parameter estimation. The importance of these methods for statistical thermodynamics


It is believed that school leadership contributes to efficiency and equity in school performance. Therefore, it is essential that professionalization initiatives for school leaders foster learning and development processes towards effective leadership. Based on a literature review, several factors appear to facilitate the influence of professionalization programs on learning outcomes of school leaders but empirical research on real effects and on explanatory processes is limited. This research gap forms the basis for this mixed methods study, in which we design and implement a longitudinal professionalization program as the research setting. We distinguish an organizational dimension focusing on structural choices and an intertwined didactic dimension. We examine which specific interaction between both contributes most to concrete learning-driven actions at the school of the participant. The results indicate that by participating in the program with such a design, school leaders prepare action plans for their own school and start up school development. The interaction between actively providing theoretical frameworks, further deepening insights through peer learning in professional learning communities, the conversion of insights into concrete action plans and supporting this with school-specific coaching leads to the strongest results, analyses show.


INTRODUCTION The SGS-Thomson X.25 Link Level Controller (MK5025) is a VLSI device which provides a complete link level data communication control conforming to the 1984 CCITT version of X.25. The MK5025 also supports X.32 (XID frames) and X.75 as well as single channel LAPD (Link Access Procedure on the D-channel) for ISDN with its extended addressing capabilities and UI (Unnum-bered Information) frames for TEI assignment. One of the outstanding features of the MK5025 is its buffer managment which includes on-chip DMA. This feature allows users to handle multiple frames of receive and transmit data at a time. In order to utilize these buffer managment and DMA features with protocols not directly supported by the MK5025, a transparent mode is also available for customized protocols using HDLC framing.


Trends and determinants of childhood malnutrition in Haiti pre- and post- the earthquake. Background The January 2010 earthquake that hit Haiti was one of the most catastrophic natural disasters of our century. Before the earthquake struck, Haiti was one of the most impoverished countries in the western hemisphere and had high child malnutrition, and poor water, sanitation, and health infrastructure. We study the changes pre- and post- the earthquake in child wasting and stunting prevalence and in addition the …


A numerical solution for the unsteady free convective heat and mass transfer in a MHD viscoelastic fluid along a semi-infinite vertical plate embedded in a non-Darcy porous medium in the presence of heat source/sink. The Walters-B liquid model is employed to simulate medical creams and other rheological liquids encountered in biotechnology and chemical engineering. This rheological model introduces supplementary terms into the momentum conservation equation. The dimensionless unsteady, coupled, and non-linear partial differential conservation equations for the boundary layer regime are solved by an efficient, accurate and unconditionally stable finite difference scheme of the Crank-Nicolson type. The velocity, temperature and concentration fields have been studied for the effect of Prandtl number, viscoelasticity parameter, magnetic parameter, Schmidt number, buoyancy ratio parameter, radiation parameter, heat source/sink parameter. The local skin- friction, Nusselt number and Sherwood number are also presented and analyzed graphically. It is observed that, when the viscoelasticity parameter increases, the velocity decreases close to the plate surface.


The use of antibiotics poses an impure public goods problem. Their utilization jointly generates a (positive) private characteristic, that is, the health of the individual who consumes the drug, and a (negative) public characteristic, that is, the reduction in susceptibility that renders the drug less effective over time. The authors use an expected utility model to explicitly identify these characteristics in a dynamic setting from a social planner perspective. The trade-off between present and future use of a drug and the allocation of resources to the development of new drugs is discussed. Results suggest that the optimal policy would limit the number of people treated with an existing antibiotic through time. Also, the model indicates that short bursts of high-level investment in research and development are optimal when the research process is certain, while a steady increase in investment over time is warranted when the discovery process is uncertain.

Choiniere, Y. and Munroe, J.A. 1993. Effect of ridge opening width on naturalventilation performance during summer. Can. Agric. Eng. 35:281-287. Inside temperatures and estimatedventila tion rates based onCO2 measurements were compared ina naturally ventilated barnundersummer conditions usingridgeopening widths of 0, 25, and 125 mm. Only minimal inside to outside temperature differences were measured for any ridge opening width during the day. There were higher frequencies of high ventilation rates with either the 25 or 125 mm wide ridge opening as compared to the closedridge; however, the estimated ventilation rates were greater than one air change per minute 80, 87, and 92% ofthe time for the 0, 25, and 125 mm ridge opening widths, respectively. The size of sidewall and ridge openings required for summer ventilation could therefore be based on wind effects alone since thermal buoyancy effects are considered to be negligible.

The state attaches great importance to the physical and mental development of college students, and attaches great importance to the positive development of college students' physical quality and mental health. Sleep quality and anxiety among college students have become the mainstream chronic diseases in colleges and universities, which are important problems to be solved urgently. The participation of long-distance running is of great value to improving students' physical quality and mental health. This paper studies the effects of experimental method and two-factor repeated measurement variance method on sleep quality and anxiety level of college students with different load intensity. The results show that long-distance running with different load intensity is of great value and significance in improving sleep quality and anxiety level of college students. However, middle-intensity long-distance running has the best effect on improving sleep quality and anxiety level of college students.


Summary. The mid-crustal earthquake of 1973 March 9 (mb= 5.5, h≤ 20 km) located 60 km south-west of Sydney, Australia, provides unambiguous evidence of contemporary thrust faulting in South-eastern Australia — a region of high heat flow and Cenozoic basaltic volcanism. Aftershock locations suggest a steeply dipping fault in the depth range from 8 to 24 km with a lateral extent of about 8 km. The mechanism solution is consistent with a tectonic stress field that is dominated by east—west horizontal compression. A seismic moment of 5.7 ± 1023± 20 per cent dyne-cm was computed from surface-wave amplitudes. Minimum values of slip and stress drop, 2 cm and 1 bar respectively, were estimated from the moment and a fault size taken' from aftershock locations.

Refinement modelling by a controlled Monte Carlo technique was used to provide unbiased models directly from multimode group velocities. The dispersion of fundamental and higher mode surface waves recorded at the digital high-gain station at Charters Towers, Queensland, and the WWSSN station at Adelaide, South Australia, is satisfied by crust- and upper-mantle models which have neither pronounced S-wave low-velocity zones nor thick high-velocity lids within 140 km of the Earth's surface. These models have subcrustal shear velocities of 4.20–4.32 km/s which are 0.4–0.5 km/s slower than Canadian shield shear velocities (CANSD).


The purpose of this study was to investigate the effect of time-compressed narration and representational adjunct images on undergraduate college students' (1) ability to recall and recognize information in a multimedia learning environment, and (2) overall satisfaction with this type of learning environment. The goals of this research were to shed light on time-compression technology incorporated into multimedia learning environments, help fill the existing gap in the research literature by merging two disjoint bodies of research, and aid instructors and instructional designers to better understand time-compression technology while creating rigorous multimedia materials.
This research was guided by the underlying principles of multimedia learning. The experiment was a 4 Audio Speeds (1.0 = normal vs. 1.5 = moderate vs. 2.0 = fast vs. 2.5 = fastest rate) x Adjunct Image (Image Present vs. Image Absent) factorial design. Audio speed and adjunct image both served as between subject conditions. Cued-recall, content recognition and learner satisfaction served as the dependent measures. Multimedia interventions were developed to execute this design.
A total of 305 research participants were recruited from a public, southeastern university in the United States in this study. Fifty-five percent of the participants were male and 92% indicated that English was their primary language. Forty-nine percent of the participants were junior classification, 4% were freshman, 19% were sophomore, 26% were seniors, with the remaining indicating other. The median age of the participants was 22, and ranges in age from 18 to 53 years old.
Data were analyzed using a series of factorial Analysis of Variance (ANOVA) procedures. Results showed statistically significant differences at 2.5 times the normal audio speed, in which performance on cued-recall and content recognition tasks was significantly lower than other audio speeds. Furthermore, representational adjunct images had a significant positive effect on cued-recall, but not content recognition. Participants in the normal audio speed and picture present groups were significantly more satisfied than other treatments. Recommendations for future research are provided as well as advice for instructors, instructional designers and learners interested in time-compression technology.


Serotonin (5-HT) has recently aroused great interest and has been linked to a number of therapeutic actions of acupuncture. It was originally discovered about 45 years ago to have a vasoconstrictor effect in the clotting mechanism, but is now known to be involved in numerous body processes including the modulation of a number of anterior pituitary hormones. Multiple 5-HT receptors have been identified and drugs with specific receptor action are being developed. Sumatripan is a 5-HT1 stimulator which has a vasoconstrictive effect, relieving migraine headaches. Ondansetron is a blocker of 5-HT3 receptors in the gut, thus being a very effective antiemetic in oncology treatment. Fluoxetine prevents 5-HT reuptake and thus has an antidepressant effect. As well as being endorphin mediated, the analgesic action of acupuncture has been shown to rely partly on 5-HT release: notably from nerves electrically stimulated at 200Hz. Acupuncture is a potent antiemetic, possibly acting by the same mechanism as ondansetron. It also has antidepressant action, perhaps through altering 5-HT mobilisation in the brain. Even the treatment of drug withdrawal symptoms by electroacupuncture may be by restabilising 5-HT at a normal level.


In the past, patients with transmural MI or STEMI accounted for most ACS admissions. Currently, though, most admissions are related to NSTEMI or unstable angina, or both. Management ofSTEMI is fairly streamlined and has been well summarized in the recent STEMI guidelines. 1 However, physicians constantly face the challenge of deciding the most appropriate diagnostic and therapeutic approach (or approaches) in patients with NSTEMI -a population that includes diverse groups ranging from patients with new-onset angina to those with a hemodynamically compromised state in the setting of ACs.z-s This challenge is complicated by the plethora of choices listed in the available guidelines, some of which are based on opinion rather than hard evidence. • The situation is compounded because of the availability of very sensitive


to us, but restarting the antipsychotic drugs she'd stopped taking soon brought her symptoms under control. She began to describe to me, in great detail, her own unique schizophrenic world. Ms. Brcnt told me that, aftcr "fighting a war within her head" for the past 40 years, she was exhausted. Vividly she described the forces of darkness and light, of good and evil--their names and the parts thcy had played in numerous battles. I sensed the intensity and fierceness of her inner

This study analyzed the coverage patterns of the media outlets OTV and MTV of the 2019-2020 Lebanese protests. Qualitative content analysis of MTV prime time news videos and OTV news articles was used to identify both media outlets' standpoints. Findings showed that the coverage patterns of MTV Lebanon and OTV Lebanon differ according to their ideological hues. In their coverage of the protests', MTV deviated from the protest paradigm as they supported the protests' cause, while OTV tended to adhere more to the protest paradigm in their coverage.


The present work describes the study of obtaining new catalysts from affordable raw materials, respectively two different types of antacid drugs and egg shells. It was also studied their efficiency in heterogeneous catalysis process. In order to determine the optimal reaction conditions, the catalysts were activated in a thermal annealing oven following to be tested the different conditions of their usage: concentration of catalyst, activation temperature, reaction time, and number of reutilizations. Aiming to standardize the process, the samples used were measured to exactly 20 mL methanol and 50 mL safflower crude oil. All the catalysts tested had high yields of over 86%; the best performance was recorded in case of a catalyst derived from pills containing magnesium carbonate and calcium (92%) in a period of about 6 hours. The biodiesel obtained was analyzed qualitatively, especially for the presence of calcium ions in solution. The catalysts revealed a good potential for utilization in biodiesel production.


Science and technology have made it possible for people to enjoy longer, richer, healthier lives but also pose existential threats to human survival. Climate change, pandemics, and the danger of nuclear war know no borders and demand a global response. Mixed with politics, economics, business, law, psychology, ethics, security, and culture, science and technology underlie issues of cyberconflict, Internet governance, competitiveness, jobs, inequality, and poverty. Unbridled use of fossil fuels disrupts the climate. Hypersonic missiles, artificial intelligence, and autonomous weapons can lead to the brink of unintended nuclear war. Cyberattacks can cripple critical infrastructure. Safeguards against these dangers have been undermined. The Internet and social media may no longer embody freedom of information, communication, and innovation. Manufacturing innovation creates new, technically demanding jobs. Tackling these issues requires disciplinary knowledge often unfamiliar to international affairs professionals. It requires confronting facts and complexities while the very idea of scientific facts is under attack.


Recent data on resonant-particle widths do not conform to the hypothesis of quantized particle lifetimes to the degree that previous data did. However, other factors not noted in a previous article may lend support to an elemental unit of time of magnitude 2.20 x 10/sup -24/ sec.


Erik Sorto had been paralyzed for 10 years when he volunteered for a bold neural engineering experiment: He would receive a brain implant and try to use the signals it recorded to control a robotic arm. Erik had no qualms about signing up for brain surgery, but his mother wasn't happy about it. "She was just being a mom," Sorto says with a smile. "She was like, 'Your brain is the only part of your body that works just fine. Why would you mess with that?'" Instead of reducing his capacities, the surgery gave Sorto superhuman abilities. In the experiments, Sorto simply imagines reaching out to grab an object and the robotic arm carries out his commands. While a handful of paralyzed people have previously used brain-computer interfaces (BCIs) to control robotic limbs, those subjects' implants recorded signals from the primary motor cortex, which is linked directly to the spinal cord and muscles. Sorto's implant was the first to record instead from the posterior parietal cortex, a brain region involved in planning movements.


Learning at PPWNI Klang Malaysia is limited in many ways, one of which is the teaching staff. There are only 2 teachers so the teacher's role is not optimal, especially in the preparation of teaching media. On the other hand, learning mathematics for elementary school students still requires concrete media as a learning tool. Therefore it is necessary to provide training for teachers at PPWNI Klang Malaysia in preparing mathematics teaching media. In the context of efficiency and effectiveness of media preparation, media based on a contextual approach were selected. The output target of this service is an increase in the competence of teachers at PPWNI Klang Malaysia in preparing mathematics teaching media. Held directly at PPWNI Klang Malaysia every working day for a full month. Training is carried out after the implementation of learning in class. Followed by mentoring activities for the development of mathematics teaching media by teachers in groups. The result of this dedication is the increased competence of teachers at PPWNI Klang Malaysia in creating learning media, as evidenced by the media that has been created.

The inherent contradiction between the energy and safety of energetic compounds makes the design and synthesis of novel energetic compounds with high density, high energy, strong thermal stability, and high sensitivity characteristics a significant and big challenge. Recently, 4-amino-7,8-dinitropyrazole-[5,1-d][1,2,3,5]-tetrazine-2-oxide (BITE-101), which was characterized to possess superior integrated properties over traditional explosive HMX, was reported by our group. To promote its further applications, the optimized and scale-up preparation of BITE-101 was accomplished in this study, and the effects of acids, the ratio of hydrogen peroxide to acids, and reaction temperature in the oxidation reaction were studied and discussed. The following oxidation conditions were found to be optimal, as follows: compound 1 (60 g, 0.26 mol), concentrated sulfuric acid (120 mL) and H 2 O 2 (360 mL). The reaction temperature was 50°C, and a yield of 28.9% was obtained. The BITE-101 preparation procedure was scaled up to 15 g. This study serves as a reference for further research on the application of BITE-101.


A clear understanding of the relationship of mechanical and acoustical excitation to electrical output of piezoelectric materials is important in the design of large‐area acoustic sensors. Chen [Il Nuovo Cimento 2 D, 1145–1155 (1983)] has reported on electrical excitation of flexural mechanical resonances that are not accompanied by detectable electrical disturbances in the ac drive circuits in a number of different specimens such as X‐ and Z‐cut quartz, Z‐cut LiNbO3, ADP, PZTs, BaTiO3, and PLZTs. These observations have raised questions about the understanding of electromechanical interactions. Speculations about the cause of the resonances include the possibility of incompleteness of the constitutive equations of piezoelectricity, surface polarization phenomena, and simple couplings due to slight structural asymmetries. In the latter regard, the objective was to see if the flexural resonances could be easily excited in a Ca‐doped PbTiO3 disk having a very small lateral piezoelectric constant (d31≊0.03d3...

PurposeThe paper describes patterns of study on innovation in the regional economic resilience literature regarding methods and findings.Design/methodology/approachThis study is a descriptive one and it uses, as a method, the scoping review based on Scopus and Web of Science databases. Forty-eight theoretical-empirical papers were thematically coded, and analyses were conducted using R packages and MaxQDA.FindingsInnovation has been used narrowly in the regional resilience literature, considering the variables, the types of shocks and the analyzed loci. From the sampled papers, this study suggests that, depending on the operationalization, the addressed relationship can be positive or negative, which still needs further investigation. In addition, the study identified two lines of research. The first, characterized by quantitative research, secondary sources and multivariate analyses, focuses on testing predictive regional resilience models based on innovation-related variables. The second, characterized by qualitative or multi-method approaches, is more concerned with explaining the knowledge accumulation and the learning capacity related to regional innovation.Research limitations/implicationsThe paper's findings show a restricted view of the innovation–resilience relationship. Although this study does not present a meta-analysis, it reveals gaps for future research. Some suggestions can be highlighted, such as (1) expanding knowledge about innovation as a predictor of resilience, (2) the theoretical development of this relationship to guide empirical investigations and (3) studies that consider the meso or micro level, approaching the role of actors in fostering innovation in the regional resilience process.Originality/valueThis paper fulfills an identified need to investigate how innovation has been operationalized in regional resilience empirical research.


Dependability can be defined by maintenance costs and how long the maintenance takes. It also can be defined in terms of continuous operation. Finally, it can be defined by how well it endures abuse or failure. The following terms help define and quantify dependability: reliability, fault tolerance or performability, maintainability, testability, availability and safety.


We accomplished a cross-sectional study using a specifically designed questionnaire. The aim of our study was to examine subjective assessment of influence exerted on healthcare workers' health and psychoemotional state by changed working conditions and use of personal protective equipment during the COVID-19 pandemic. The examined healthcare workers were employed at a multi-field re-profiled in-patient hospital. We established a considerable change in the workplace setting of healthcare workers in an unfavorable epidemic situation. It involved longer contacts with hazardous biological and chemical factors, elevated work hardness and intensity as well as the necessity to use personal protective equipment for a long time. Longer use of personal protective equipment when tending COVID-19 patients was associated with higher frequency of several variable complaints made by the questioned healthcare workers. Respondents were more likely to report difficulty in breathing (p < 0.001) and some discomfort around the face and/or behind the ears (p = 0.035) when wearing a medical face mask / respirator; wearing goggles was likely to involve itching, redness and/or maceration in the area where goggles contacted the head (p = 0.009), headache (p = 0.002) and discomfort in the area where goggles contacted the head (p < 0.001); healthcare workers who wore medical gloves reported itching (p = 0.004) and skin peeling (p < 0.001); use of protective overalls led to elevated sweating (p < 0.001), feeling overheated (p < 0.001), thirst (p < 0.001), and palpitation (p = 0.012). A significant proportion of respondents experienced some difficulties in using personal protective equipment related to visual and auditory perception of information, physical discomfort, putting on and taking off personal protective equipment, performance of work requiring precise movements, and decreased work capacity. The frequency of such complaints grew statistically significantly during a period when a healthcare worker had to treat COVID-19 patients.


In New phenomenology in France, Laszlo Tengelyi invites us to think about the transformed relationship between the notions of possibility and reality in the contemporary French phenomenology. To justify his thesis, he proposes to examine Marc Richir's criticism of «transcendental Ideals» in Husserl's and Heidegger's phenomenology. In considering, next to Tengelyi, Richir's revisit of phenomenology as an extension of the Kantian criticism of ontotheological metaphysics, the present study aims to develop three main ideas. First, it scrutinizes Kantian criticism of the ontological argument in Critique of Pure Reason. The ontological argument considers transcendental Ideal as a reality, with there being confusion between an object of pure thinking and one of knowledge. Second, this study aims to clarify the way in which Richir also applies Kantian criticism to Husserl's transcendental eidetics as well as to Heidegger's existential analytic, in Experience of Thinking – Phenomenology, Philosophy, Mythology and Phantasia, Imagination, Affecitivity. On the one hand, by analyzing Husserlian manuscripts on transcendental intersubjectivity, Richir uncovers a disguised form of the transcendental Ideal, incorporated in the notion of form of essence or «Eidos» of the existing I; this notion is presupposed as a condition of passage from the possibility to the reality of the Other. On the other hand, Richir discovers in the Heideggerian description of «anticipation of death» in Being and Time, a dissimulated concept of the transcendental Ideal that takes a form of the Dasein's «ownmost» [eigenst] factual possibility. Ultimately, the main purpose of the current study is to show that contemporary French phenomenology intends to release itself from the transcendental Ideal, which is considered a reality that presupposes the total sum of possibilities.


With aqueous hypochlorite and a phase transfer catalyst, secondary alcohols undergo hitherto unreported free radical reactions that compete with and effectively limit traditional ketone syntheses. Product mixture profiles are determined by reactant ratios, organic cosolvent, and availability of oxygen to the system. Under argon, over half of substrate alcohols, PhCH(OH)R, are converted to benzaldehyde and free radical products through beta-scission of intermediate alkyl hypochlorites. Secondary alcohols with R containing three or more carbons also may undergo delta chlorination.


Throughout history, organizations for collective action have emerged and been sustained voluntarily. Greif (1993), Wade (1988), Ostrom (1990, 2000), and Mokyr (2011), among others, demonstrate the capability of autonomous social organizations to emerge and to agree on sharing the burden of funding broadly beneficial activities. The great historian of Britain, T. S. Ashton (1948, p.88) writes that, "In the 18th century, the characteristic instrument of social purpose was not the individual or the State, but the club. Every interest, tradition, or aspiration found expression in corporate form" . While many of these organizations had a narrow business purpose, others did not. Some organizations built hospitals, canals, orphanages, and also contributed to the regulation of new professions. Those organizations filled the void created by a weak state.


Considering production and reserve status, price terms of trade, and business indexes, the empirical study shows that the rise in the price of China's rare earth export does not indicate the rise of its international pricing status. The further quantitative analysis of the impact of rare earth prices finds that production volume and export volume are negative influencing factors, but market concentration is one of the biggest positive contribution factors, followed by new materials consumption ratio, industrial structure index and resource tax. Therefore, we should change the asymmetric oligopoly structure of the market, strictly manage resource and environmental protection, promote the extension of industry chain to the high-end, attach great importance to the national finance and tax policy support, and so on.


which is implemented on a reconfigurable modular robot called SuperBot. In this paper, the design of SuperBot is first reviewed, and then the configuration design and locomotion control of tricycleBot is described. Two different wireless controllers are used to remotely control tricycleBot. Experiment results show that tricycleBot is capable of carrying payloads more than 5 times of its own weight with satisfactory speed. It can also be steered remotely to move forward/backward, turn left/right, and travel over 1 km on a fully charged set of batteries in a carpeted office environment, or over 2 km on a smooth marble surface.


The research on walnut crops carried out at the Botanical Garden aimed at conserving genetic resources, analyzing the segregation of morpho-anatomical characters in some walnut selections, to breed and patent new cultivars, to obtain new rootstocks resistant to diseases and pests and to analyze the best combinations of scions and rootstocks. For more than 50 years, Professor Ion Comanici has carried out multiple studies on the biology of walnut, in parallel with the research on vegetative propagation. The study on the variability of populations has highlighted a vast local gene pool, which currently constitutes the genetic basis for the breeding of valuable cultivars.


Summary: The results of treatment of anovulatory infertility over a 6‐year period, which included the introduction of gonadotrophins and clomiphene citrate, are presented. Two hundred and sixty patients have been treated, and 139 of these became pregnant. Eighty‐nine of the first 100 completely treated patients had no other infertility factors and 69 of these (78%) achieved at least 1 pregnancy. The reasons for withdrawal from treatment before successful pregnancy had occurred included problems of remote management, and the acceptance of adoption. Four patients required psychiatric advice for disorders occurring during the treatment regimen.


In this work, a new approach is proposed to determine both the thickness and permittivity of coatings on circular PEC cylinders. The approach is based on Generalized Impedance Boundary Conditions (GIBC) which is defined in terms of thickness and physical properties of the layer and Born approximation method. Numerical results are presented to show the applicability of the method.
