Abstract : Over the past 70 years, the free-floating aquatic fern Salvinia molesta D. S. Mitchell (giant salvinia) has spread from its native range in Brazil to many tropical and subtropical regions. Though innocuous within its native range, elsewhere this species is an aggressive menace that has had devastating ecological and socioeconomic impacts on aquatic systems in parts of Africa, Sri Lanka, India, Australia, New Guinea, and the Philippines. In the United States, the plant is established in waterways in at least 10 states (mainly in the south) and is expected to continue to expand in areas generally where Eichhornia crassipes (Mart.) Solms (water hyacinth) persists. Listed as a Federal Noxious Weed since 1984, S. molesta is prohibited from importation to the United States and from transport across state lines. Dense mats of S. molesta can suppress growth of native vegetation and degrade water quality, fish and wildlife habitat, and numerous other ecological values. Notably, massive infestations have occurred in the Swinney Marsh Complex, Texas, in the Lower Colorado River, Arizona/California, and in Lake Wilson and Enchanted Lake, Hawaii. This report presents a review of available information on the growth, distribution, and ecology of S. molesta. Information is provided on the plant's taxonomic status, its field characteristics, phenology, and spread overseas and in the United States. Growth responses of S. molesta in relation to environmental variables (e.g., temperature, nutrients, light, pH, conductivity) are emphasized as are impacts of the species on the environment and other aquatic organisms Different technologies (i.e. physical chemical biological and integrated) applied to control S. molesta infestations are discussed along with information on the effectiveness of these procedures and their need for further study.


Stark broadening of hydrogen lines is investigated in low-density magnetized plasmas, at typical conditions of magnetic fusion experiments. The role of time ordering is assessed numerically, by using a simulation code accounting for the evolution of the microscopic electric field generated by the charged particles moving at the vicinity of the atom. The Zeeman effect due to the magnetic field is also retained. Lyman lines with a low principal quantum number are first investigated, for an application to opacity calculations; next Balmer lines with successively low and high principal quantum numbers are considered for diagnostic purposes. It is shown that neglecting time ordering results in a dramatic underestimation of the Stark effect on the low- lines. Another conclusion is that time ordering becomes negligible only when ion dynamics effects vanish, as shown in the case of high- lines.


The ~200 km diameter Chicxulub crater in the Yucatan carbonate platform in Mexico is currently considered the K/T impact site, responsible for the K/T global ejecta layer. In this work we report results of the studies of the impact breccia sequence cored in the UNAM-5, UNAM-6, UNAM-7 and Yaxcopoil-1 boreholes. UNAM drilling program involved continuous coring of the Tertiary carbonate sequence and the impact lithologies. Yaxcopoil-1 borehole was drilled a year ago as part of the Chicxulub scientific drilling project, in the southern sector of the crater. The Chicxulub deep drilling is part of the International Continental Drilling Program. Coring started at 400 m and was continuous to the final depth of about 1.5 km. We concentrate on the initial studies of the breccia sequence where apparent fragments of meteorite are present and descriptions of the fragments. These findings provide a unique opportunity to investigate on the nature of the Chicxulub impactor, from the study of the impact-related material directly recovered inside the carter. Identification of impactors forming large terrestrial craters is a difficult problem, mainly because, in contrast to small impacts in which fragments can be preserved, no physical evidence survives the high-energy events. Investigations can be based on analyses of the crater melt rocks and/or melt-rich ejecta. Chemical data on Ni, Cr, Co and PGE contents and interelement ratios have been successfully used in large crater studies. However, fractionation during melting in large impacts, vaporization, condensation, etc can modify chemical composition. Further, subsequent processes of hydrothermal alteration, metamorphism, diagenesis or weathering may alter or erase the chemical signature. Survival of parts of the impacting body in large impacts is restricted by the high temperature/pressures attained and vaporization of impactor. This has been considered the case for the Cretaceous/Tertiary large impact, with siderophile material present into the fine-grained global ejecta layer.


The canonical voltage-gated calcium channel (VGCC) subunit complex is comprised of the α1 subunit, the ion permeable channel, plus three auxiliary subunits: β, α2δ and γ. β is the most extensively studied auxiliary subunit and is necessary for proper forward trafficking of the α1 subunit to the plasma membrane. α1 subunits mediate voltagedependent movement of calcium ions into the cytoplasm of neurons, including at dendritic sites, where increased intracellular calcium initiates signaling cascades that shape structural and functional plasticity of dendritic spines. Genetic studies strongly implicate calcium signaling dysfunction in the etiology of neurodevelopmental disorders including schizophrenia. Dendritic spine density (DSD) is significantly decreased in schizophrenia in primary auditory cortex where DSD is driven by loss of small spines, and small spine loss is associated with increased peptide levels of ALFDFLK found in the VGCC β subunit β4. Overexpessing CACNB4 to increase β4 levels selectively reduced small spine density in cortical neuron cultures. The studies described herein set out to validate this in vitro observation in an intact mammalian system within a neurodevelopmental context. We overexpressed CACNB4 in neurodevelopment and assessed DSD and morphology in cerebral cortex of male and female mice at an adult timpoint. We then characterized β protein levels and β4 protein-protein interactions in male and female mouse cortex. Overexpression selectively reduced small dendritic spine density but this effect was present only in female mice and did not appear to result from estrous stage. Instead, the sex-dependent effect on DSD corresponded to sex differences in the β4 interactome of male versus female mice: the VGCC β subunit β1b was significantly enriched in the β4 interactome of brain tissue of male mice, and thus may have served to mitigate VGCC overexpression-mediated spine loss in male mice.


We track 38,000 money market trades from execution to delivery and return, and provide a first empirical analysis of settlement delays in financial markets. In accord with the predictions of recent models of strategic settlement of financial claims, we document a tendency by lenders to delay delivery of loaned funds until the afternoon hours. We find banks to follow a simple strategy to manage the risk of account overdrafts, by delaying settlement of large payments relative to that of small payments. More sophisticated strategies such as increasing delays when own liquid balances are low and when dealing with small trading partners play a marginal role. We find evidence of strategic delay also when returning borrowed funds, although we can explain a smaller fraction of the dispersion in delays in the return than in delivery leg of money market lending.


A novel cellular concrete with millimeter-level pores fabricated with superabsorbent polymers and fiber is introduced. Porous structure with reinforcement of fiber are adopted to improve crack resistance and shock-absorbing ability. To investigate the dynamic mechanical performance of fiber-reinforced cellular concrete, quasistatic compression and split Hopkinson pressure bar tests with strain rate from 15 to 90 s−1 were conducted. Three different fiber volume fractions (0.2%, 0.6%, and 1%), and two types of fibers (polypropylene fiber and basalt fiber (BF)) were adopted. Along with two levels of porosities (20% and 60%), total of 12 mix designs of cellular concrete to three-level axial impacting. The research results show that the novel cellular concrete is sensitive to high strain rates, demonstrating increasing dynamic compressive strength, dynamic elastic modulus, dynamic increase factor (DIF), and peak toughness with the increase in strain rate. In addition to the inertia effect, the locally enhanced porous structure and fiber structure can change the stress field and crack path, along with the energy consumption of deformation and cracks in the pores. The amount of fiber, physicochemical property, distribution, and shape amplify or dampen through its thickening effect, interface reaction, and stress transmission. Recommended fiber types and dosages were proposed to improve strength, stiffness, and toughness. BF showed an enhanced performance in terms of strength, modulus, and sharp strain-rate effect. Rules of DIFs were also studied. Awareness of the dynamic properties provides a foundation for proper design of structural members and increases the use of cellular concrete.


This paper has been prepared for publication from several papers written some years ago. It is essentially a new presentation of the more important features of the earlier papers. The paper is about the transonic area rule, which states that the variation of zero-lift drag of an aircraft configuration at transonic speeds depends primarily on its axial distribution of cross-sectional area. The detailed discussion concerns a more restricted but more explicit result, namely that the drag jump (the discontinuity in zero-lift wave drag predicted by linearised theory at sonic speed) of a smooth wing-body combination is given by a formula which involves only the area distribution of the combination; this result is called the sonic area rule. The present treatment of the sonic area rule is one of exploitation rather than explanation. The paper does not consider in detail the relation of the sonic area rule to the entire problem of drag rise, but makes some contributions to the use of the sonic area rule in the design of wing-body combinations of low drag rise. Resuks for several optimum area distributions for minimum drag jump are given, in a more compact and enlightening form than hitherto. Some simple, yet fairly general, cases of the design of wing-body combinations of low drag jump are discussed, and a numerical example is given; the cases investigated illustrate some of the principal features of design for low transonic drag rise.


Elimination of a biological entity from a sizeable area is a challenging approach to an age-old problem. Undesirable insects, disease organisms, nematodes, weeds, rodents, even birds, frequently create economic problems when they are permitted entry into new areas. "From time immemorial," said Parrott (1), "inroads of injurious insects on agriculture have been regarded as inevitable handicaps for whleh there was little or no amelioration." This is no longer true. We find no references in literature prior to the late 19th century i~dieating that anyone seriously considered the possibility of eradicating an insect once established in a new land. The theory of eradication thus can be considered as relatively new. The term "eradicate" means to destroy, remove utterly, complete destruction, or removal in general; thus "exterminate" is a synonym. To the professional entomologist, "eradication" means extermination or elimination of an insect population, and the term is generally applied with reference to an incipient infestation of an insect new to an area or not widely distributed. We now have a background of experience that permits us to draw some conclusions. Some 30 years of experience in suppressing incipient infestations of pests introduced into the United States provide data on which to measure success or failure as the case may be.


Stability of the Higgs vacuum during early universe inflation is dependent on how the Higgs couples to the spacetime curvature. Limits on the curvature coupling parameter at the electroweak scale $\xi_{EW}$ are shown to be consistent only when quantum gravity effects are included and a covariant quantisation procedure, such as Vilkovisky-DeWitt, is adopted. Stability requires $\xi_{EW}>-0.03$ for a top quark mass $M_t=173.34\,{\rm GeV}$.


OBJECTIVE To analyze the clinical features and risk factors of chronic cervicitis and to provide reference for its prevention and treatment.METHODS The clinical data of 42 cases with chronic cervicitis treated in our hospital from Jan to Jun 2011 were analyzed retrospectively to summarize the clinical features.And 42 healthy subjects were chosen as the control group for analyzing the risk factors of chronic cervicitis.RESULTS Cervical erosion was the main clinical characteristics of patients with chronic cervicitis,accounting for 59.5%.The patients with chronic cervicitis with 55 years of age or older accounted for 26.2%,the patients with less than 55 years of age,accounted for 73.8%,the patients with IUD placement 83.3% laboring workers 76.2%,the patients in rural area 71.4%.CONCLUSION It is neccesary to take corresponding countermeasures in accordance with the risk factors for chronic cervicitis so as to reduce the incidence of chronic cervicitis.


In this paper,a water droplet motion model in thermal insulation countercurrent air flow is built based on the non-spherical particle drag coefficient,and the explicit formulation for terminal velocity is derived.On the basis of this model,the influence of water droplet deformation and internal flow on drag force and terminal velocity is studied.It is shown that with the increase of deformation,drag force on water droplet is increasing,but the terminal velocity is(decreasing).When considering internal flow of water droplet,the drag force decreases within a maximal deviation of 15%.


The On-Time Disclosure Rule, implemented by the U.S. Department of Transportation in 1987, makes reports of the on-time performance of the major U.S. carriers available to the public. The purpose of the disclosure rule was to create incentives for the carriers to improve their on-time performance by either reducing the amount of time to complete a flight or lengthening the amount of time scheduled for a flight. The evidence shows that although actual flight times have fluctuated, scheduled flight times have increased significantly since 1988. The largest increases occurred just after the disclosure rule went into effect, and a regression analysis shows that since 1988, on-time performance has been a significant factor in the scheduling decisions of many carriers. Then two scheduling strategies are presented that are designed to improve on-time performance. The strategies are implemented, and their performance is compared with the performance of the carriers' schedules. The comparison highlights the challenges that carriers face when designing schedules with the disclosure rule in mind.


Interlayer diffusion and interdigitation in Langmuir-Blodgett multilayers containing asymmetric interfaces between cadmium arachidate (CdA) and an octadecyl-substituted polyglutamate (PG) were studied using neutron reflectometry and X-ray reflectometry. It was found that the structure of the two-component CdA/PG multilayers is less stable to annealing than is the structure of multilayers containing only CdA or only PG. The PG side chains and CdA tails at adjoining layers appear to interdigitate significantly in unannealed multilayers, and this interdigitation becomes more marked after annealing.


Organizations will capitalize on social media marketing with the use of analytics. Big data allows entities to study various facets of consumer behavior and develop marketing strategies. The use of analytics gives businesses a direct competitive advantage over those who do not use such tools. The use of sentimental analysis curtailed risk management issues as the COVID-19 pandemic disrupted the masses.


Membrane protein crowding may influence the biological processes that drive vesicle formation. The surfaces of biological membranes are very crowded places (1, 2). "Steric pressure" created by interactions between membrane proteins can influence important aspects of membrane behavior, including the lateral diffusion of membrane proteins (3), the architecture and function of cell adhesion proteins (4), and cargo selection in clathrin-mediated endocytosis (5, 6). On page 1359 of this issue, Čopič et al. (7) propose that surface-crowding effects can also influence the bending of membranes into highly curved structures such as transport vesicles.


A series of logical events must occur for a pathogen to spill over from animals to people. The pathogen must be present in an animal reservoir, it must be shed from the reservoir into the environment or be transferred from the reservoir to a vector, it must persist in the environment or vector until contact with a human or amplifier host, and it must successfully enter, colonize, and reproduce within the human. These events each represent a barrier the pathogen must cross to successfully infect a human. Percolation models of pathogens completing the series of barriers or logical events can connect models of spillover risk with standard tools for statistical inference. Here, we develop percolation-based models of spillover risk and a theoretical framework for managing spillover as an inextricably multilevel process. Through analysis and simulation, we show that estimated associations between level-specific covariates and spillover events will err towards associations from dominant pathway to spillover, a potential problem if there are alternative pathways to spillover with different associations with covariates. Furthermore, estimated associations between covariates and spillover will better reflect associations between covariates and success probabilities of bottleneck events with the highest pathogen attrition rates in the data observed. If one agrees with a percolation model for spillover, then GLMs should not be used to estimate relative importance of various levels. We recommend always using nonlinear models for predicting spillover risk with quantitative covariates and discuss why switching regression models may be well suited for avoiding some obvious pitfalls in predicting spillover from alternative pathways or wildlife reservoirs. Finally, we demonstrate how percolation models formalize an intuitive management paradigm for mitigating risk in the inherently multilevel process of pathogen spillover.

As the basic system of the rescue robot, the SLAM system largely determines whether the rescue robot can complete the rescue mission. Although the current 2D Lidar-based SLAM algorithm, including its application in indoor rescue environment, has achieved much success, the evaluation of SLAM algorithms combined with path planning for indoor rescue has rarely been studied. This paper studies mapping and path planning for mobile robots in an indoor rescue environment. Combined with path planning algorithm, this paper analyzes the applicability of three SLAM algorithms (GMapping algorithm, Hector-SLAM algorithm, and Cartographer algorithm) in indoor rescue environment. Real-time path planning is studied to test the mapping results. To balance path optimality and obstacle avoidance,

 algorithm is used for global path planning, and DWA algorithm is adopted for local path planning. Experimental results validate the SLAM and path planning algorithms in simulated, emulated, and competition rescue environments, respectively. Finally, the results of this paper may facilitate researchers quickly and clearly selecting appropriate algorithms to build SLAM systems according to their own demands.


EXECUTIVE LEADERSHIP AND POLITICAL DECISION-MAKING: A CASE STUDY OF THE DEVELOPMENT AND EVOLUTION OF THE COMMUNITY COLLEGE SYSTEM IN THE COMMONWEALTH OF MASSACHUSETTS 1957-1962 SEPTEMBER 1994 JAMES H. MULLEN, JR., B.S., COLLEGE OF THE HOLY CROSS M.S., HARVARD UNIVERSITY Ed.D., UNIVERSITY OF MASSACHUSETTS AMHERST Directed by: Professor William C. Wolf, Jr. Politics plays an inevitable and integral role in the development of policy concerning higher education at the state level. Governors are fundamental to the political process of statewide higher education policymaking. This study examines the role which two governors played in the early development of community colleges in Massachusetts between 1957 and 1962. The purpose of this study is essentially two-fold. First, it seeks to tell a political story about two governors of different personalities, parties, and policy priorities. Focusing on the common historical theme of community college development, this story presents how the contexts of their times influenced the strategies and decisions of Foster Furcolo (1957-1960) and John Volpe (1961-1962) and how, in turn, these two men shaped the period in which they lived. The second purpose of this study is to analyze specifically how Furcolo and Volpe influenced the critical


This paper gives the distribution of the independent variable in a first-order autoregressive equation which is necessary for the modelled variable to have a mixed exponential marginal distribution. Restricting attention first to a mixture of two exponentials which is probabilistic, a solution is shown to exist over a restricted range of the first serial correlation; tabulations of the boundary values are given. The independent variable has a distribution which includes a discrete component at zero and a not necessarily probabilistic mixture of three exponentials. The marginal distribution is then considered with a negative mixture weight; this weight is shown to be lower bounded in value, but not to depend on the first serial correlation.


Infection with the HIV has become a pandemic and has posed a great health problem both in developed and developing countries. In response to the above most developed countries offer routine screening to all pregnant women and to test them for HIV after counseling and obtaining informed consent. In developing countries this approach has also been suggested but has not been seriously implemented. Following the increasing incidence of HIV infection throughout the world a policy of routine HIV screening for pregnant women was adopted in the obstetric department of the University of Nigeria Teaching Hospital Enugu Nigeria in the latter part of 1998. In a retrospective analysis of the antenatal records of 600 women 234 (39%) failed to have the HIV test performed even when they had consented to it. Some of the reasons for non-testing include the high cost of routine screening and lack of structure for taking care of HIV positive pregnant mothers and their babies. In this regard developing countries should emphasize on prevention through education information and communication. Health education campaigns should be intensified as well as prevention and treatment of sexually transmitted diseases changes in behavioral patterns of the people promotion of barrier methods of contraception and the practice of monogamous faithful relationships. These cost-effective interventions are worth exploring in resource poor countries; governments and other health care providers are called upon to make this a priority.


These studies investigated the effectiveness of in vivo administration of cytokines in ameliorating potential marrow damage induced by chemotherapy. Breast cancer patients received 5‐fluorouracil, leucovorin, doxorubicin and cyclophosphamide (FLAC) followed by either GM‐CSF, PIXY321, or no cytokine. Marrow was obtained before and after one or two cycles of FLAC once blood cell counts had recovered. Colony‐forming units for granulocytes and macrophages (CFU‐GM) were used to indicate the effect of therapy on recovery of committed progenitor cells responsible for early blood cell recovery. The frequency and number of CFU‐GM in marrow obtained after FLAC + PIXY321 were significantly lower than in marrow obtained after FLAC + GM‐CSF or FLAC without cytokine. CD34+ cell numbers were also reduced after FLAC + PIXY321. CFU‐GM production in marrow long‐term cultures (LTC) was used to assess the effect of therapy on primitive progenitors. After 5 weeks the number of CFU‐GM in LTC of post‐therapy marrow from all three treatment arms was < 15% of the number in pre‐therapy LTC. Suppressive effects of FLAC on primitive progenitors were observed even when committed progenitors and CD34+ cells had recovered to pre‐therapy levels. These results demonstrate that cytokine treatment did not ameliorate suppressive or toxic effects of FLAC on the functional integrity of the marrow.


Background: Macular recovery after surgery for retinal detachment depends on pre-operative and post-operative predictive factors. Pre-operative factors, which influence macular recovery negatively, include duration of macular detachment, height of macular detachment and vitreomacular traction. Post-operative factors, which influence macular recovery negatively, include cystoid macular edema, epiretinal membranes, retinal folds, subretinal Retinal Pigment Epithelium (RPE) migration and persistent subretinal fluid. OCT has elucidated several postoperative factors correlating with poor vision. These features include persistent SRF and increased foveal thickness ,demonstrating as well the submacular fluid that couldn't be detected clinically. OCT can detect persistent foveal detachment, distortion and disruption of Outer Retinal Layers (ORLs) and macular folds following successful surgery for RD. FAF has been used to investigate the morphological and functional changes occurring after RD repair. Objective: The aim of our study is to correlate the structure-function relationship of the macula following successful repair of rhegmatogenous retinal detachment, by correlating the SD-OCT and FAF macular images with BCVA. Study Design: Prospective observational case series study. Patients and Methods: Forty-five eyes underwent surgical repair of RRD followed by SD-OCT and FAF imaging one to three months post-operative. SD-OCT and FAF findings were correlated with post-operative BCVA. Results: Forty-five eyes achieved complete post-operative reattachment with 95.6% SOSR. The values of BCVA showed significant difference between eyes with the following OCT findings: Macular edema, persistent SRF, RPE-choriocapillaries complex, IS/OS junction disruption and neurosensory detachment and eyes not showing the same OCT changes (p 0.05). The values of BCVA showed significant difference between eyes showing hyper-autofluorescence on FAF imaging and eyes not showing hyper-autofluorescence (p=0.015). Correspondence to: Dr. Mariam R. Fadel, The Department of Ophthalmology, Faculty of Medicine, Cairo University We found significant association between fundus hyperautofluorescence and the following OCT findings: Macular edema, RPE-choriocapillaries complex irregularity, IS/OS junction disruption and neurosensory detachment. Conclusion: SD-OCT is considered a valuable tool for evaluating the microstructural changes at the macula. The IS/OS junction disruption, persistent SRF, macular edema, neurosensory detachment and RPE-choriocapillaries complex irregularity are considered vital measures affecting the structure and function of the macula and can explain the incomplete visual recovery despite an anatomical successful RD surgery. Fundus autofluorescence is a non-invasive imaging modality that evaluates the function and health of the photoreceptor and the RPE layers showing great advantage in analyzing the macular function abnormality.


Purpose: To compare dynamic multileaf collimator (DMLC) and helical tomotherapy (TOMO) IMRT delivery techniques for head and neck re‐irradiation. Method and Materials: Five cases were selected. For each case, a planning target volume (PTV) and the spinal cord were contoured. A 5 mm margin was added to the spinal cord to create a planning organ‐at‐risk volume (PRV). Plans were developed to deliver 60 Gy to 95% of the PTV while minimizing PRV dose. For DMLC delivery, 7 fields in the transverse plane were used. Plans were developed for two secondary collimator configurations, one in which the collimators were set by the optimization engine (DMLC STD) and one in which the PRV was always blocked by a collimator jaw (DMLC BLOCK). For both DMLC STD and TOMO, the optimization parameters were adjusted to minimize the PRV dose without exceeding 69 Gy to a volume of tissue >1 cc. DMLC BLOCK plans were optimized using the same parameters as the DMLC STD plans. The PTV D1cc, spinal cord D0.5cc, and non‐specified normal tissue D1cc were calculated. Results: The TOMO plans were able to both minimize the spinal cord dose and limit the hotspot. The DMLC plans were not able to limit the hotspot to the extent of the TOMO plans. The DMLC BLOCK plans achieved equivalent cord sparing, but with increased dose heterogeneity. The mean spinal cord D0.5cc, was 8.8, 16, and 8.4 Gy for the TOMO, DMLC STD, and DMLC BLOCK plans respectively. The mean PTV D1cc was 67.7, 68.6, and 71.4 Gy and the normal tissue D1cc was 65.2, 68.2, and 71.5 Gy. Conclusion: Dynamic MLCIMRT is capable of producing spinal cord sparing equivalent to helical tomotherapy. However, with current technology, the sparing is at the expense of PTV heterogeneity and larger doses to small volumes of normal tissue.


Severe scaling problems have been encountered in the pipeline networks in the lowtemperature geothermal field in Kebili, South Tunisia, due to the chemical changes resulting from degassing, evaporation and cooling that are necessary to produce a valid water for oasis irrigation. Data from three wells: Kebili-Ras Elain-C.I.10, Om Somaa-C.I.5 and Lymagues-C.I.8 was analysed to study the calcium carbonate scaling potential. One scaling sample and two pipe samples from Kebili-Ras Elain pipeline network were also analysed for scale identification by microscope and X-Ray Diffraction. The scale consisted mainly of aragonite. Two chemical models, the WATCH program and the SOLVEQ program were used to predict calcite and aragonite scaling, and to determine the allowable supersaturation before calcium carbonate formation becomes a problem. The saturation index, log (Q/K), for the two calcium carbonate polymorphs are high. For calcite the log (Q/K) exceeds 1.50 and for aragonite at the final step log (Q/K) exceeds 1.30, which indicates that the CaCO3 scaling problems will occur. Based on these findings more accurate predictions of calcium carbonate scaling can be made.


wholly omitted. Similarly on the presence or absence of members of aristocratic and 'new' families in the ' fasti' under Augustus is chiefly based the discussion of Augustus' general policy at different times in his Principate. Here again the point is original and ingenious, and the appendices in which the ' fasti' are analysed contain most useful matter; but the students for whom the book is presumably intended would need to be warned that other considerations of at least equal importance receive little or no attention. But with these cautions the book may be safely recommended as a useful and reliable guide to what is after all the most important of all periods of ancient history.


Hybrid palm ash/silica/natural rubber composites were prepared using a laboratory-sized two roll mill. The effects of partial replacement of palm ash by silica on curing characteristics, mechanical properties, and morphology of hybrid palm ash/silica/natural rubber composites were investigated. Compared to the control composite (30 phr of palm ash), increasing the silica in the weight ratio of silica/palm ash increases the scorch time and cure time, the maximum and minimum torques, and enhances the rubber—filler interaction, tensile strength, tensile modulus, and fatigue life. However the incorporation of palm ash also exhibits the beneficial effects by shorter curing time of hybrid palm ash/silica/natural rubber composites.


Background Acute myeloid leukemia (AML) is a complex, heterogeneous neoplasm characterized by the accumulation of complex genetic alterations that are responsible for the initiation and progression of the disease. Secondary AML (sAML) represents a progression from antecedent hematologic disorders such as myelodysplastic syndromes (MDS) or myeloprolifrative neoplasms (MPN). Certain acquired mutations have been reported to be specific for sAML when compared to primary AML (pAML), but many limitations exist when cytogenetic grouping or other parameters are taken into account. In addition, some mutations have been shown to impact survival in some studies, but not others. Methods We performed targeted deep sequencing on samples from bone marrow and peripheral blood of pts diagnosed with sAML and pAML and treated at our institution between 1/2003-1/2013. Additional data on pAML was added from The Cancer Genome Atlas (TCGA). A panel of 62 gene mutations described as frequently recurrent mutations in myeloid malignancies were assessed. Cytogenetic grouping was defined by CALGB/Alliance criteria. Differences were compared using Fisher9s exact test and the Mann-Whitney U test for categorical and continuous variables, respectively. Overall survival (OS) was calculated from the time of diagnosis to last follow up or death. Results: A total of 496 pts included: 273 with pAML and 223 with sAML. Comparing pAML to sAML, pts were younger (median age 59 vs. 68 years, p 9 /L, p 3 abnormalities) compared to 11% and 16% for pAML ( p ASXL1 ( p JAK2 ( p =.014), CBL ( p =.05), BCOR ( p =.02), STAG2 ( p =.003), SF3B1 ( p =.04), SRSF2 ( p =.001 ), and U2AF1 ( p =.03) were highly specific for the sAML phenotype, whereas mutations in NPM1 (p FLT3 ( p DNMT3A ( p IDH2 ( p =.02) were more specific for pAML. When the analysis was restricted to pts with NK cytogenetics, only ASXL1 (p DNMT3A (p ASXL1 (p=.01) remained specific for sAML. No other mutations were specific for pAML. We then evaluated whether the mutations that were specific to each AML phenotype had an impact on OS. We observed different mutations that impacted OS in each phenotype: DNMT3A (HR 1.81, 95% CI 1.28-2.57, p TP53 (HR 3.1, 95% 1.74-5.53, p SUZ12 (HR 3.18, 95% CI 1.01-10, p=.05) led to worse OS in pAML, whereas mutations in EZH2 (HR 2.12, 95% CI 1.07-4.21, p =.03), PRPF8 (HR 2.32, 95% CI 1.20-4.46, p=.01), and TP53 ( HR 2.92, 95% CI 1.69-5.04, p FLT3 (HR 2.15, 95% CI 1.37- 3.35, p DNMT3A (HR 2.41, 95% CI 1.57-3.70, p BCOR (HR 2.41, 95% CI 1.57-3.70, p TP53 (HR 2.41, 95% CI 1.57-3.70, p BOCR (HR 2.95, 95% CI 1.03-8.50, p SF3B1 (HR .19, 95% CI .05-.82, p SUZ12 (HR .12, 95% CI .01-.99, p TP53 (HR 1.9, 95% CI 1.09-3.46, p Conclusion Clear genomic variations exist between sAML and pAML. Although some of these genomic changes are more specific to each phenotype in general, this specificity and the impact on OS differed for each cytogenetic subgroup, highlighting the complexity of interpreting genomic information in pts with AML and the need to incorporate both cytogenetic and molecular data in prognosis-driven treatment decisions.

This paper is an investigation into the semantics of ability attributions ("AAs"), i.e. sentences (or utterances) that are used to ascribe some individual some ability. AAs come in various different shapes.,and forms and the extent to which the components responsible for their distinct semantics are disguised or shown transparently varies accordingly. Below are a few examples to give an impression of the range of facts that 1 think belong ultimately to this


Scholars have suggested that the elderly need close, intimate relationships to enhance the quality of their lives. These relationships can be found in closest friendships. In the present study, we aimed to determine self-perceived variable patterns in the closest friendship relational network of both, one, or neither gender among nonconfined aged males. Specifically, we examined the most frequently perceived variable patterns with reference to the particular structural friendship unit, then reported on the similarities and/or differences among the groups.


As a typical large-flow high-head pump, the vertical long-axis fire pumps have the advantages of rapid startup, superior structure, and strong applicability in multiple occasions. In order to shorten the non-overload optimization cycle, CFturbo, ICEM and CFX are integrated by writing batch processing commands to achieve automatic multi-load and no-load optimization of vertical long-axis fire pumps based on Isight's multi-disciplinary optimization platform. With the objective of achieving the non-overload characteristics of vertical long-axis fire pumps, the optimal Latin hypercube design is used to spatially sample the design variables of the impeller. After sampling, the particle swarm optimization (PSO) algorithm is used to optimize the design. The results show that, vertical long-axis fire pumps achieve non-overload characteristics within 1.5Q 0 after optimization, while the head and efficiency at the rated operating point are almost unchanged.


This study aims to develop alternatives for making vegetable protein based feed for the growth of African Catfish seeds (Clarias gariepinus) by utilizing flour made from Kiapu (Pistia stratiotes). This research was conducted for ± 1 month, namely from September to October 2017. The place of this research was conducted at the Laboratory of Aquaculture Study Program, Department of Fisheries, Faculty of Agriculture, University of Palangka Raya. From the research that has been carried out it can be concluded that the growth rate of length and weight of African Catfish seeds during the observations showed good results. The use of kiapu flour as an addition to the Prima Feed commercial feed on the growth of African Catfish seeds shows a response to weight and length growth. However, for Fengli Fl-1 type feed, kiapu flour which is given in conjunction with Prima Feed type feed is still under Fengli Fl-1 type feed. Conversion of feed from Fengli Fl-1 commercial feed is lower than Prima Feed commercial feed mixed with kiapu flour.

Keywords : Additional feed, kiapu flour, African Catfish seeds.


Charcot-Marie-Tooth disease (CMT) is the most common inherited peripheral polyneuropathy in humans, and its subtypes are linked to mutations in dozens of different genes, including the gene coding for ganglioside-induced differentiation-associated protein 1 (GDAP1). The main GDAP1-linked CMT subtypes are the demyelinating CMT4A and the axonal CMT2K. Over a hundred different missense CMT mutations in the GDAP1 gene have been reported. However, despite implications for mitochondrial fission and fusion, cytoskeletal interactions, and response to reactive oxygen species, the etiology of GDAP1-linked CMT is poorly understood at the protein level. Based on earlier structural data, CMT-linked mutations could affect intramolecular interaction networks within the GDAP1 protein. We carried out structural and biophysical analyses on several CMT-linked GDAP1 protein variants and describe new crystal structures of the autosomal recessive R120Q and the autosomal dominant A247V and R282H GDAP1 variants. These mutations reside in the structurally central helices α3, α7, and α8. In addition, solution properties of the CMT mutants R161H, H256R, R310Q, and R310W were analysed. All disease variant proteins retain close to normal structure and solution behaviour. All mutations, apart from those affecting Arg310 outside the folded GDAP1 core domain, decreased thermal stability. In addition, a bioinformatics analysis was carried out to shed light on the conservation and evolution of GDAP1, which is an outlier member of the GST superfamily. Many CMT mutation sites are highlighted in the bioinformatics analyses focusing on sequence conservation and entropy, and the analyses support the outlier nature of GDAP1 in the GST superfamily. A central role for the α6-α7 loop, within a conserved interaction network, is identified for GDAP1 protein stability. To conclude, we have expanded the structural analysis on GDAP1, strengthening the hypothesis that alterations in conserved intramolecular interactions may alter GDAP1 stability and function, eventually leading to mitochondrial dysfunction, impaired protein-protein interactions, and neuronal degeneration.


Main sequence stars are commonly surrounded by debris disks, composed of cold far-IR emitting dust generated by a reservoir of undetected dust-producing planetesimals. In debris disks harboring massive planets, the trapping of dust in gravitational resonances with the planet creates a density enhancement in a ring-like structure outside the orbit of the planet, while gravitational scattering with the planet creates a clearing of dust inside the planet's orbit. Massive planets, therefore, can create structure in the dust disk, and the study of this structure can help us survey a range of planetary parameters that are not detected by other methods. Spitzer will obtain spatially unresolved spectrophotometric observations of many of these systems. We discuss how the structure carved by massive planets affects the shape of the disk's spectral energy distribution (SED), and consequently how the SED may be used to infer the presence of planets. We show, however, that the SED modeling presents some degeneracies that can only be broken if spatially resolved images of the dust disks are obtained, justifying the need of SAFIR for the interpretation of debris disk structure in terms of planetary architectures. In addition, the very high sensitivity of SAFIR will allow us to understand whether debris disks originate from a steady production of dust, or from stochastic collisional events. SAFIR will provide unique capabilities to study stars at a stage when terrestrial planet formation might be taking place, results that will allow us to learn whether terrestrial planets are common or rare.


This is a follow-up study of an earlier one in which positive effects of early day-care experience were found on children's cognitive and socioemotional competence at age 8. 128 children were followed from their first year of life. At 8 and 13 years of age, 92% and 89% of the children, respectively, remained in the study. Most children could be classified according to age at first entry into day-care. Cognitive and socioemotional competence was rated by the children's classroom teachers. Hierarchical regression and path analyses were used in the statistical treatment of the data. It was possible to trace independent positive effects of age of entry into day-care as far as age 13. Children entering center care or family day-care before age 1 generally performed better in school when 8 and 13 years old and received more positive ratings from their teachers on several socioemotional variables. The path analyses indicated the following causal model: family characteristics, such as type of family, family's socioemotional status, and mother's educational level, influence the time of first entry into day-care. This variable, in turn, has consequences for children's competence at 8 and/or 13 years of age even after controlling for home background, child gender, and intelligence, which, of course, have their own effects. The effect of socioeconomic status was often mediated through age of entry into day-care.


The concept of reforming of the budgetary process in Russia in 2004-2006, approved by the resolution of the Government of the Russian Federation of May 22, 2004 No. 249 (further the Concept), defined a number of tasks and the directions of improvement of the budgetary process. It is obvious that with implementation of the Concept financial control at federal level also should undergo changes, on level of statement of tasks and control methods to correspond to the checked phenomena subjected to reforming and processes.


The orthogonal cutting-stock problem tries to place a given set of items in a minimum number of identically sized bins. Combining the new BLF2G heuristic with an advanced genetic algorithm can help solve this problem with the guillotine constraint. According to the item order, the BLF2G heuristic creates a direct placement of items in bins to give a cutting format. The genetic algorithm exploits the search space to find the supposed optimal item order. Other methods try to guide the evolutionary process. A new enhancement guides the evolutionary process, enriching the population via qualified individuals, without disturbing the genetic phase. The evolution of the GA process is controlled, and when no improvements after some number of iterations are observed, a qualified individual is injected to the population to avoid premature convergence to a local optimum. A generated set of order-based individuals enriches the evolutionary process with qualified chromosomes. The proposed method is compared with other heuristics and metaheuristics found in the literature on existing data sets.


The paper presents a model for the local bond-slip relationship in well-confined concrete that can be used for monotonic, cyclic, and fatigue-type loadings. The model is based on load- and slip-controlled cyclic and fatigue tests of local bond specimens reported here, as well as tests performed at the University of California, Berkeley. The model's parameters are all related to the bar's deformation pattern and can be quantified directly from the physical dimensions of the bar and the concrete strength. A simple damage rule was developed based on the total slip excursion and the amount of friction lost. Additional work is needed to generalize the model for it to be applicatble to any scale.

A useful and convenient method for sp3 C–P(O) bond formation via direct regioselective hydrophosphinylation of simple and readily available alkenes using a lanthanum-based N,N-dimethylbenzylamine complex (La(DMBA)3) as a precatalyst is demonstrated. The reaction proceeds with perfect atom economy for a wide range of styrenes with secondary phosphine oxides, giving moderate to excellent yields.


In the present study, an interactive mode of the computing system has been developed for the hydraulic analysis of the circulating waters in the industrial pipings. The system consists of three separated modules, which are linked together with common graphical user interfaces. Application to the design of the cooling sea-water system for the ships was demonstrated to be very reliable and practical in support of design activities.


Plants procure phosphorus from soil as the phosphate anion. It is the most un-portable component in plant and soil in comparison to other macronutrients. It's very well known that phosphorus is the second most significant supplement after the nitrogen required/needed in plant growth. It is a fundamental component in every single living system. Barely 1%-2% of phosphorous is provided to different parts of the plants. It precipitates in soil as orthophosphate or is adsorbed by Fe and Al oxides through legend exchange. Phosphorus-solubilizing bacteria play a substantial part in phosphorus nutrition by increasing phosphorus' accessibility to plants through discharge from inorganic and natural soil P pools by solubilization and mineralization. Lowering the pH of the soil through microbial generation of natural acids and mineralization of natural phosphorus by acid phosphates is the key element in the soil for mineral phosphate solubilization. Chemical composts are used as an additional source of phosphorous to satisfy the plant's need. Additionally, co-inoculating P solubilizing microorganisms with other beneficial bacteria and mycorrhiza has shown to increase their efficiency. Microbial inoculants or biofertilizers can thus be used as an alternative source because they are both economical and environmentally favourable.


The mobile telephone is the representation of mobile communication. In this paper we proposed a new machine translation method called Super-Function Based Machine Translation (SFBMT) to try to use for mobile terminal. SFBMT uses Super Function(SF) to translate the sentence without thorough syntactic and semantic analysis. And it can translate the sentence fast and high correct. Our experiment shows that this method can get 70% translation precision using the sentences that learned for extracting Super-Function, And 40% translation precision using the sentences that not learned for extracting Super-Function.


THE term engineering is employed with many different shades of meaning. Tredgold's famous definition of civil engineering, which appears in the charter of the Institution of Civil Engineers (London), dating from 1828, commences with the excellent phrase "—the art of directing the great sources of power in nature for the use and convenience of man—." In Tredgold's time there were only two recognised types of engineering — i.e. civil and military. At the present time, nearly forty different branches of engineering have been itemised in technical literature. For the purposes of this discussion the following broad definition is suggested to cover all types of non-military engineering: "the economic application of the sciences to construction, production or useful accomplishment, especially on a large scale."


Hierarchical Optimal Problem is characterized as mathematical programming to solve decentralized decision making problems. The simplest case is two level optimal problem, which is usually thought of as two DMs at two different hierarchical levels, and is called bi level programming problem or static Stackelberg game too. The review on literatures of the BLP problems and multi level problems is presented. It presents the basic models and their characterizations of these problems as well as the related areas for further research.

Ignazio Angeloni believes that the increase in financial interdependence in recent decades has not been matched by sufficient progress in the international coordination among regulatory authorities. In fact, the international financial system has suffered from insufficient globalisation of regulatory and supervisory policies, not excessive globalisation of financial markets.


The author proposes an effective capacitor control model for unbalanced radial and meshed distribution systems. Due to the linear characteristic of the proposed model, a constant sensitivity matrix relating the incremental capacitor shifts and system status can be derived, and then the sensitivity-based objective function and network constraints can be obtained. The linear formulation can be solved by the commonly used linear programming and integer programming techniques, which are among the best choices for real-time control in terms of computational speed, reliability, and ability to handle many different operating constraints. The development of the sensitivity matrix does not need any assumptions about voltage magnitudes, voltage angles, line r/x ratios, and network topology; thus, the proposed method can achieve high robustness and accuracy. The proposed capacitor control model can be used to solve the capacitor placement and real-time capacitor control problems; however, in order to verify the accuracy of the model, only the corrective dispatching problem is solved in this work. Test cases including the unbalanced radial and meshed distribution systems and a large-scale distribution system acquired from Taiwan Power Company are all conducted. Test results show that the proposed method can effectively handle the capacitor control problems and has great potential to be integrated into distribution automation.


Under standard equilibrium assumptions, a bidder in an independent private value auction chooses her bid by trading off between markup and probability of winning. Under similar assumptions, a producer in a differentiated product market chooses its price by trading off between markup and residual demand. This similarity in the nature of the problem lands itself to a striking similarity in the first order conditions, which form the basis for estimation. Despite these similarities, the two literatures evolved in very different directions; much of the auction literature emphasizes nonparametric identification and nonparametric estimation techniques, while the demand literature concentrates on (parametric) ways to deal with endogeneity of prices. This note tries to provide a unified framework which nests the two literatures, thereby clarifying the differences in assumptions that made the literatures go in such distinct directions.


Mixed iodide‐bromide organolead perovskites with a bandgap of 1.70–1.80 eV have great potential to boost the efficiency of current silicon solar cells by forming a perovskite‐silicon tandem structure. Yet, the stability of the perovskites under various application conditions, and in particular combined light and heat stress, is not well studied. Here, FA0.15Cs0.85Pb(I0.73Br0.27)3, with an optical bandgap of ≈1.72 eV, is used as a model system to investigate the thermal‐photostability of wide‐bandgap mixed halide perovskites. It is found that the concerted effect of heat and light can induce both phase segregation and decomposition in a pristine perovskite film. On the other hand, through a postdeposition film treatment with benzylamine (BA) molecules, the highly defective regions (e.g., film surface and grain boundaries) of the film can be well passivated, thus preventing the progression of decomposition or phase segregation in the film. Besides the stability improvement, the BA‐modified perovskite solar cells also exhibit excellent photovoltaic performance, with the champion device reaching a power conversion efficiency of 18.1%, a stabilized power output efficiency of 17.1% and an open‐circuit voltage (V oc) of 1.24 V.

Lettuce plants grown in sand culture, and recelvmg nitrogen, phosphorus, and potassium at five levels in all combinations, were analysed at different stages of growth for these elements. An attempt was made to relate these analytical data to the growth response following a supplementary application of phosphorus.


A simple, extractive spectrophotometric method for the trace determination of thorium is developed using 5-chloro-7-iodo8-hydroxyquinoline as a complexing agent for the metal ion in neutral solution. The resulting complex bears a metal to ligand ratio of 1: 4 whose absorption maximum lies at 390nm. The method obeys Beer's law in the range 0-15 µg Th (IV) ml -1 with a molar absorptivity and Sandell's sensitivity value of 1.09 × 10 4 L mol -1 cm -1 and 0.0213µg Th(IV) cm -2 respectively. It is also free from the interference of a large number of cations and anions. Utilizing the proposed procedure, the analysis of various synthetic samples has been carried out to a greater degree of accuracy.


In this paper, we propose a nonlinear back-stepping controller (NBC) to damp the generator oscillations and improve the transient stability in multi-machine power systems. An observer is designed to estimate the inaccessible states, which is different from previous back-stepping designs with complete states of the whole system. Moreover, in order to counteract the destabilizing effect of the observer errors, observation errors are treated as disturbances and accounted for using nonlinear damping term. Different from other back-stepping controller design in power system before, the proposed controller is designed on a reduced forth order nonlinear model of a synchronous generator with which the voltage error of steady state is decreased. The stability of the system is verified by Lyapunov methods. The 3-machine power system is applied to demonstrate the effectiveness of the proposed controller over tuned power system stabilizers.


The good quality patchouli plants, it takes patchouli cuttings that have good initial vegetative growth. The initial vegetative growth in plants is an important phase that supports the further growth of patchouli until the productive phase. To produce patchouli plants with good initial vegetative growth, fertilization is necessary to ensure the availability of nutrients needed in the metabolic process of patchouli plants. Patchouli plants require adequate amounts of nutrients, especially macro nutrients such as nitrogen and others which can be done by administering NPK with the right dose and frequency of administration. The results showed that (1) the treatment of patchouli cuttings (treatment B) had a very significant effect on the growth of patchouli at week 2,4,6,8,10 and 12 WAP. Meanwhile, the concentration of liquid NPK fertilizer (treatment A) had a very significant effect only at the age of 10 and 12 WAP for the number of leaves. (2) The treatment of the number of patchouli cuttings (treatment B) had a significant effect on the growth of patchouli at week 4 WAP, had a very significant effect at week 2,6,8 and 12 WAP. As for the treatment, the concentration of liquid NPK fertilizer (treatment A) had a significant effect on week 8 MST and had a very significant effect at week 10 and 12 MST for the number of shoots (3) There was an interaction between the two treatments, namely at the age of 10 and 12 MST while on the number of shoots only occurred at the age of 12 MST


The main advantage of Soraa's GaN on GaN (Gallium Nitride on Gallium Nitride) LED material is that it allows reliable operation at very high current densities. It has 1000x fewer defects than conventional LEDs, which have GaN layers on cheaper foreign substrates like sapphire, silicon carbide, or silicon. This enbles Soraa LEDs to emit 10x more light per unit area of LED material than conventional LEDs. GaN on GaN's optical transparency and high thermal and electrical conductivity also enable a very robust, simple LED design that delivers maximum light output and performance.


Objective To explore the effect of hypertension treatment by combination of felodipine and fluoxetine through ambulatory blood pressure observation.Methods Totally 110 patients with hypertension were randomly divided into two groups.The combination group was given both felodipine and fluoxetine,while the simple group was given felodipine only.After the treatment lasting for 6 weeks,ambulatory blood pressure observation was applied to observe the mean daytime value,mean nighttime value,24H value of blood pressure,blood pressure rhythm,efficacy and quality of life as well as lifestyle changes.Results Compared with the combination group,the mean daytime value,mean nighttime value,24H value of blood pressure of systolic blood pressure were all high in the simple group(P 0.05).Except the mean nighttime value,the other two values in simple group were superior to those in combination group(P0.05).There were significant differences on the level of efficacy and blood pressure rhythm between two groups(P0.05).The fluctuation of both SBP and DBP in combination group were less than the simple group.The improvement of following indices in combination group were significantly greater than the simple group such as body,role,emotional,cognitive,social function,overall health score and Hamilton Depression Rating Scale score.After the Health intervention,there were significant changes in the lifestyle and habits compared with the situation before intervention.Conclusions The treatment in combination of felodipine and fluoxetine shows an satisfactory effect in the therapy of hypertension,manifesting in both the ambulatory blood pressure observation and the improvement of lifestyle and habits.

Abstract This study examined the relationship of activity readiness with self efficacy, perceived behavioral control, exercise attitudes, self-rated health, and selected demographic variables among high functioning, independent-living elderly. Four hundred seventy-one subjects, ranging in age from 62 to 93 years, were drawn from a popular retirement area and data were gathered through a self-report survey instrument. Subjects residing at no exercising readiness stages held negative self-efficacy, behavioral control, and attitudinal beliefs whereas regular exercisers held positive beliefs toward these constructs. Perceived behavioral control was most indicative of active lifestyle attainment, suggesting intervention strategies designed to initiate and maintain activity in the high functioning elderly focus on control belief cognitions.


Recent research suggests that Recurrent Neural Networks (RNNs) can capture abstract generalizations about filler-gap dependencies (FGDs) in English and so-called island constraints on their distribution (Wilcox et al., 2018, 2021). These results have been interpreted as evidence that it is possible, in principle, to induce complex syntactic knowledge from the input without domain-specific learning biases. However, the English results alone do not establish that island constraints were induced from distributional properties of the training data instead of simply reflecting architectural limitations independent of the input to the models. We address this concern by investigating whether such models can learn the distribution of acceptable FGDs in Norwegian, a language that is sensitive to fewer islands than English (Chris-tensen, 1982). Results from five experiments show that Long Short-Term Memory (LSTM) RNNs can (i) learn that Norwegian FGD formation is unbounded, (ii) recover the island status of temporal adjunct and subject islands, and (iii) learn that Norwegian, unlike English, permits FGDs into two types of embedded questions. The fact that LSTM RNNs can learn cross-linguistic differences in island facts therefore strengthens the claim that RNN language models can induce the constraints from patterns in the input.


For the last decade in Indonesia, pharmacist roles and responsibilities has been
more expanding from medication dispensing to patient-focused care services
(Pharmaceutical Care). This alteration consequently will affect pharmacist-patient
professional relationship, including interpersonal communication. To determine the
relationship, pharmacist and patient rely on role perceptions of one another, which
also form expectations of one another and influence the produced interaction.
The aim of study is to describe the patients' expectation of pharmacist associated
with Pharmaceutical Care practice in Puskesmas.
We developed a semi-structure interview guide using a focus group of clinical
pharmacists. The interview guide was used to direct face-to-face patient interviews
at 5 different Puskesmas in East Java. The interviews were conducted in April and
May 2011, recorded and transcribed verbatim. The interview transcripts were
analysed to determine related themes.
Total 10 interviews were conducted. Several themes emerged from interview
transcripts were medicines services, medicines information, self-surrender, and
speedy health recovery.
The lack of patients' understanding of pharmaceutical care services could be one
reason for the minimal patients' expectation from pharmacist.


ABSTRACT Background: Starting from the "frontal lobe hypothesis of cognitive aging", we aim to study the metacognitive functions (deception, reciprocity, cognitive and affective theory of mind), autonomy and quality of life in normal aging. Methods: Eighty healthy subjects (30 young adults [YA] aged 20–40, 30 old adults [OA] aged 65–79 and 20 very old adults [VOA] aged 80 and over) participated in our study. Standard and novel neuropsychological tasks have been used, assessing abilities to understand others' mental and affective states, deceptive and cooperative situations. Results: OA and VOA's performances are significantly poorer than those of YA on first-/second-order false beliefs, deception, reciprocity and emotion recognition tasks. VOA have made more errors than other participants on control false beliefs, general cognition, and memory tasks. Normal aging seems also to be characterized by a reduction in processing speed. The level of instrumental activities of daily living decreases with aging. Theory of mind is associated with individual general cognitive state and executive functions, but not with OA and VOA's levels of autonomy and quality of life. Conclusion: In this study, we have shown an age-related deterioration of metacognitive functions, which does not seem to be associated with old adults' autonomy and satisfaction of life. A good level of mental activity could be necessary to maintain satisfactory interpersonal relationships.


Within a production machine, various electromechanical and pneumatic structures can be used for drive tasks. As these drive technologies can often replace each other, the energy efficiency, performance and TCO of pneumatic drives must be permanently enhanced to remain competitive. There is a large number of known measures for the reducing their energy consumption, e.g. minimizing of filling volumes, energy saving circuits etc. However, these measures are mainly considered separately and the possible overall energy saving effect resulting from their combination is rarely taken into account. The main goal of this paper is therefore to explore the possible combinations of pneumatic energy saving measures and their cumulative saving effect. Due to the fact that some measures are mutually exclusive (e.g. a general pressure reduction in properly sized drive), each combination should be considered separately. To evaluate their efficiency plausibly, a comprehensive assessment is required that contains both the total cost of ownership analysis (TCO) and a mechanical properties assessment. The presented comprehensive approach of the task analysis can serve as example of how an optimal drive configuration for the specific task can be found, thus creating a basis for solving constructive challenges in designing of pneumatic automation systems.


Assessment of land exploitation potential is a basic foundation for scientific exploitation of the land. As there're numerous factors affecting exploitation potential of the land, so far no well-recognized mature theory and methods are available for its assessment. Based on the real conditions of Luzhai County, Guangxi, this paper brings forward an index system which includes 13 factors. It uses the fuzzy comprehensive evaluation model to assess exploitation potential of the virgin land in Luzhai County, GuangXi. Besides, it discusses some essential issues related to establishment of the index system and identification of assessment standard. The paper raises some useful suggestions on how to exploit the virgin land in Luzhai County.


The study of categorical data is one of the most crucial part of statistical analysis. Modeling for these data has been considered by many authors in terms of log linear, logit, probit and logistic models. Mixed effects models containing both fixed and  random effects are useful in a variety topics in the physical, biological and social sciences. In present study, some considerations have been sought in parallel categorical data such as the relation between the past and presentwith some rigorous modeling techniques. The relation is usually depicted via random effects. Random effect distribution can control the correlation among variables in longitudinal study in an appropriate way. When the response variable is an ordinal random variable, random effect distribution is taken as multivariate normal distribution. According to Azzalini(1985) the skew normal distribution has better properties and it is more efficient. In the present paper, an attempt has been made to study mixed effects model wherein the random effects follow skew normaldistribution given by Azzalini (1985).The mixed model is considered for longitudinal ordered categorical data. A method for estimating the model parameters has been explored. The properties of the proposed model have been investigated in terms of validity and efficiency. Comparisons have also been made between fixed effect model and model with skew normal random effects. Simulation have been carried out for finding the estimates of the model parameters.

According to the flexible force sensor capable of measuring the normal force and tangential force, the flexible supporting layer is adopted to replace a traditional solid dielectric layer, the capacitance change value generated when stress is conducted on the sensor is effectively increased, and the force measuring sensitivity is improved remarkably.


In this article we consider two linguistic facts which occured in Brazil during the years 1930-1940: first, the project of the Parliament to change the name of the language spoken in Brazil from Portuguese language to Brazilian language; second, the campaigns for nationalizing the educational system, intended for the large wave of European immigrante. Those campaigns aimed at teaching immigrants Brazil's national language and at officially discouraging them from talking or writing their own languages. From these two facts, one can see how citizenship and Brazilianity are related to the general questions of language and nationality. At the root of those juridical measures there is a discursive formulation of national unity and linguistic homogeneity, related to the heterogeneity of Brazilian society.


Man, W. Va., Aug. 1, 1902. To the Editor: —Progress is the ever restless, unsatisfied, aggressive law of human wisdom and experience, and the march of this unsatiated human intellect, in every direction, is ever onward and upward, and will be so to the end of time. So long as knowledge increases, opportunity is multiplied and with it, additional motives, to ambitious incentive, drive the wheels of effort and energy in all the fields of scientific enterprise. Thus we find the standard of excellence of to-day placed up on a higher elevation to-morrow, such progression continuing unceasingly, ever seeking but never reaching the greatest heights, which lie in the limitless beyond. What a stupendous thought is this—No limit to human attainment! Yet the country practitioner gathers very little from the modern medical journal and many of the text-books of new authors from the fact its discussions deal almost exclusively with


The concepts of the 'public sphere', 'public opinion' and the 'public use of reason' have a long and complex genealogy. Jurgen Habermas' (1989) early study, The Structural Transformation of the Public Sphere, traces much of that genealogy, revealing the shifting meanings that have attached to these concepts and the various struggles and socio-historical changes which have occasioned them. In recent years, however, it has been Habermas' own work on the public sphere, both in Structural Transformation and later studies, which has set the agenda for much of the debate on these issues. Habermas has been criticized, extensively and perhaps sometimes unfairly. But even when his work has been strongly criticized it has remained central. This book has been compiled with the aim of deepening and extending the Habermasian project by way of both an engagement with Habermas and, more particularly, a consideration of other theories and frameworks which afford us different ways of problematizing and exploring the public sphere. Although we cannot speak for our contributors, we, as editors, believe that it is important to begin to consider other possible frameworks for understanding the public sphere than those presented by Habermas. Or rather, since this process has already begun (see below), to provide a central reference point where some of the main alternatives can be brought together. This book is therefore 'after Habermas' in two senses. It follows him to a point but then seeks also to break new ground beyond his work. We will offer a brief overview of the alternatives considered in the book in the latter part of this introduction. First, however, it is necessary briefly to reiterate the main points of Habermas' own position and some of the key criticisms that have been levelled against him. It is only against this yardstick that it will be possible to gauge whether the various attempts to move beyond Habermas, as spelled out in the main chapters of the book, really do constitute useful alternatives or additions.


ABSTRACT
Positron emission tomography (PET) is a nuclear medicine imaging method with increasing relevance for the diagnosis, prognostication, and monitoring of glioblastomas. PET provides additional insight beyond magnetic resonance imaging (MRI) into the biology of gliomas, which can be used for noninvasive grading, differential diagnosis, delineation of tumor extent, planning of surgery, and radiotherapy and post-treatment monitoring. In clinical practice, two classes of radiotracers have been used predominantly for imaging purposes, namely glucose metabolism tracers and amino acid transport tracers. Both classes of tracers can provide information on grading and prognosis of gliomas, but amino acid tracers, which exhibit lower uptake in normal brain tissue, are better suited for delineation of tumor extent, treatment planning, or follow-up than 18F-2-fluoro- 2-deoxy-D-glucose (18F-FDG). Owing to the progress in PET imaging using radiolabeled amino acids in recent years, the Response Assessment in Neuro-Oncology (RANO) working group, an international effort to develop new standardized response criteria for clinical trials in brain tumors, has recently recommended amino acid PET as an additional tool in the diagnostic assessment of brain tumors. These developments as well as multimodality imaging should improve the diagnostic assessment of these tumors.


This paper summarizes the work for defining a new protocol. The goal was to create a multicast routing protocol, which works in an IP over ATM network and-unlike the existing ones-is truly scalable. After studying the literature, we realized that no existing protocol is fully suitable for these requirements, so modifying an existing one we created a new routing protocol. In the first chapter we discuss the necessity of developing such a protocol. Next we provide the goals for the new protocol and the results of the studies of the existing proposals, moreover some words are told about the essentials of our new protocol. In the third chapter we summarize the pros and the contrast of the most scalable proposal: SEAM. In the fourth part of this documentation we show, how to manage the multicast tree in order to reach the best efficiency of network resource utilization.


Building on studies of L1 error effects in writing, the present study aimed to gain further insight into thecommunicative consequences of actual and perceived L2 errors in writing by investigating their effects beyond theevaluation of text quality. No studies of L2 writing would appear to have investigated the impact of errors onperception of the author and communicative outcomes. We investigated the effect of L2 English errors in persuasivewriting on native and non-native English speakers' evaluation of the text, of the author, and of the persuasiveness ofthe text. Selected, authentic, errors from a corpus of petitions written in English by Dutch native speakers wereincluded in a stimulus text. Two versions of the text were presented to (non-teacher) participants in a 2 (errors vs. noerrors) by 2 (native vs. non-native judges) between-subject experimental design. It was found that, while actual errorhad no effect on the participants' evaluation of the text, the author, or the persuasiveness of the text, perceived error(that is, if participants thought the text contained errors) had a significant negative effect on text attractiveness andthe author's trustworthiness, friendliness and competence. Thus, the findings would suggest that perceived errorplays an important role in how non-teacher judges evaluate a text and its author, and, more generally, that suchjudges would seem to use their own standards of correctness against which to judge writing and the writer, regardlessof whether the judges are native or non-native speakers.


This paper shows how state wage surveys can be used to compare the earnings of public and private sector workers within states. This subject of long-running interest to economists has generated a complex and sometimes contradictory set of empirical results. Surprisingly little, if any, of this academic work has used the publicly available wage surveys that many states routinely collect. This paper serves as an introduction to such surveys and an application of the Wisconsin State Wage Survey for the purpose of comparing public and private compensation. While the evidence generally indicates public earnings are higher, we are careful to point out the limitations of our methodology which suggests this conclusion is incomplete.


According to uncertainty management theory, this research examined the effect of the Organization's Leadership and Supervision (OLS) and Training and Development (T&D) on employees' satisfaction among employees of casual restaurants. This research presented the environment of work as a mediating variable to describe and clarify the correlation between OLS, T&D and employees' satisfaction. This Research developed all measurements using scales suggested by previous authors. The current research depends on the longitudinal form for data collection. A five-point Likert scale used to test the attitude of the participators toward research variables. 135 Participators shared in this survey are full-time workers employed at casual restaurants located at Greater Cairo. Data collected analyzed using SPSS (23) and AMOS (23) statistical tools. Path analysis approach used to test the research conceptual model. The research found that work environment partiallymediates the effect of OLS and T&D on employees' satisfaction at casual dining restaurants.Casual dining restaurants should develop adequate training programs and care about their work environment to increase employees' satisfaction and adjust their attitude through changing circumstances

A kinetic study was carried out on the solvolysis of benzoyl bromide, BzBr, benzoyl chloride, BzCl, and benzoyl fluoride, BzF, in microemulsions of AOT/isooctane/water at 25 °C, where AOT is sodium bis(2-ethylhexyl)sulfosuccinate. In all cases, the pseudo-first-order rate constant, kobs, increases together with the [AOT] as a consequence of incorporating the substrates into the interface of the microemulsion. The application of a kinetic model based on the formalism of the pseudophase, which considers the distribution of the reagents between the continuous medium and the interface and that the reaction is taking place only at the interface, has enabled us to obtain the intrinsic values of the rate constant at the interface of the microemulsion for the three benzoyl halides, . The values of vary together with the water content of the microemulsion. The study of the variation of with W (W = [H2O]/[AOT]), the correlations with the ET polarity parameter, and the effect of the leaving group have allowed us to ...


The present study sought to determine the nature of the correlation and impact relationship between the dimensions of employees empowerment and strategic dexterity at Cihan University/Erbil under study. The study was based on the development of a questionnaire consisting of (34) paragraphs for the purpose of measuring the dimensions and variables according to the Likert scale of five weights. As a mechanism for this study in achieving its objectives, two main hypotheses were developed indicating a significant correlation between the dimensions of employees empowerment and strategic dexterity (collectively and individually). And a significant effect on the dimensions of employees empowerment in the strategic dexterity (collectively and individually). The questionnaire was distributed to the functional and teaching staff at the researched university. The study chose a random sample of (75) forms, of which 58 were valid for analysis, ie, the response rate was 77.33%. The study used statistical methods to process, analyze and reach the results by adopting the SPSS program.


In 2009–2010, record warming occurred in the South Pacific and western Antarctica. To document the oceanic and atmospheric conditions associated with the sea surface temperature anomalies, Lee et al. analyzed satellite and in situ observations.

The anomalous warming in the south central Pacific region began in September 2009 and reached a record high in December, around the same time that the 2009–2010 central Pacific El Nino peaked. The amplitude of the South Pacific warming was more than 5 times larger than the usual variability in the region and was substantially stronger than the concurrent El Nino. The spatial extent of the South Pacific warming was comparable to the size of the continental United States and was associated with an unusually strong and persistent high-pressure system.


Yager's entropy was proposed to compute the information of fuzzy indiscernibility relation. In this paper we present a novel interpretation of Yager's entropy in discernibility power of a relation point of view. Then some basic definitions in Shannon's information theory are generalized based on Yager's entropy. We introduce joint entropy, conditional entropy, mutual information and relative entropy to compute the information changes for fuzzy indiscerniblity relation operations. Conditional entropy and relative conditional entropy are proposed to measure the information increment, which is interpreted as the significance of an attribute in fuzzy rough set model. As an application, we redefine independency of an attribute set, reduct, relative reduct in fuzzy rough set model based on Yager's entropy. Some experimental results show the proposed approach is suitable for fuzzy and numeric data reduction.


This paper is aimed to investigate the potentiality of describing and differentiating optical-anisotropic properties of biological liquid crystal net by statistic analysis of coordinate distributions of a new analytical parameter, a complex degree of mutual anisotropy.


The European Centre for Medium-range Weather Forecasts' (ECMWF) Composition - Integrated Forecast System (C-IFS) provides global operational forecasts and re-analyses of atmospheric composition at high spatial resolution (~80 km). In this thesis the C-IFS system, with Global Fire Assimilation System (GFAS) emissions, is used to assess the impact of fires on tropospheric ozone and aerosol concentrations. The skill of the model and the impact of data assimilation is evaluated using independent aircraft, ground and satellite observations. In particular, observations from the 2012 South American Biomass Burning Analysis (SAMBBA) field campaign is used as a case-study. This work represents the first evaluation of trace gas observations from SAMBBA.
C-IFS simulations show that 4% of the total tropospheric column is produced by fire emissions, with significantly larger contributions closer to fire sources. Compared to both SAMBBA aircraft measurements and Ozone Monitoring Instrument (OMI) satellite data (0-6 km column) O3 concentrations are underestimated in the tropics. Evaluation of precursor emissions show that this is due to a combination of NOx flux underestimation in GFAS and the lack of a prescribed injection height, partly acting through a subsequent limited influence of PAN. Carbon monoxide, a tracer of biomass burning transport, is well captured by C-IFS implying that GFAS detects the majority of fires although the occurrence of small ones appears underestimated.
The assimilation of satellite reactive gas measurements from OMI, Measurements Of Pollution In The Troposphere (MOPITT) and the Microwave Limb Sounder (MLS) generally improved the C-IFS comparison against SAMBBA and other independent data. The O3 tropospheric representation was improved by MLS assimilation but a significant negative bias against OMI (0-6 km column) remained. The chemical data assimilation impacts non-assimilated species such OH with increases up to 8% in the tropics. However, compared to observations this degraded the OH Northern/Southern hemisphere ratio and the impact of the OH change on other species was minimal.
Fires in C-IFS are shown to dominate the global carbonaceous aerosol budget during the tropical fire season. Aerosol concentrations are slightly underestimated by C-IFS compared to SAMBBA. The relative contribution of black carbon (BC) and organic matter (OM) is similar to that observed in the eastern savannah but the contribution of BC is overestimated in the western deforestation region. The use of the suggested ×3.4 GFAS scaling factor leads to a large positive bias in the model aerosol compared to SAMBBA. The assimilation of aerosol optical depth (AOD) generally decreases concentrations near fire-sources, due to this scaling, but still increases concentrations in remote regions. This suggests an inaccurate model loss of aerosol is a cause of the bias. The analysis/model bias used to characterise a more realistic local scaling factor which is shown to be different for BC and OM, and for AOD metrics compared to aerosol mass.


Largely through the work of Ranson and his associates (1), inability of the kidney tubule d to resorb water in normal quantity has been established as the primary functional disturbance in the patient suffering from the syndrome of diabetes insipidus. Because of the large volume of urine thus secreted, such subjects seem peculiarly adapted to a study of the action of hormones and other agents which are apparently capable of affecting water and electrolyte balance in the body. Three patients with diabetes insipidus, two of the persistent and one of the intermittent type, have served as the basis of the study. In each of these three patients the presence of diabetes insipidus has been proven by the use of water-deprivation and saltloading tests when the patients have been successively on a dietary of average, low, and high salt content, respectively. methods and procedure Each of the three patients with proven diabetes insipidus was hospitalized for several weeks prior to a study of the influence of various...

Two red chalk drawings unearthed among the anonymous sheets in the Pinacoteca Civica, Varallo, are here attributed to the Bolognese artist Ubaldo Gandolfi. One of them matches a drawing in the Fondazione Giorgio Cini in Venice; the other, an image of Clemency, is a study for the monochrome painting of the same subject frescoed by Ubaldo in a salone of the Palazzo Malvezzi in Bologna as part of the Apotheosis of Hercules.


There has been much recent interest in using a nonlinear lensing element combined with an aperture to produce a saturable absorber for laser modelocking. [1, 2] This Kerr-lens-modelocking (KLM) technique normally uses the gain medium as the nonlinear element, but lasers with separate gain and nonlinear elements have also been demonstrated,[3] allowing application of this method to lasers in which the gain medium does not provide adequate self-focusing or gain-guiding. The analysis we have carried out seems to indicate that the nonlinear element need not be self-focusing; in fact, it appears that a larger effect can be obtained by a self-defocusing element. Additionally, in the ring resonator geometry we consider, the intensity-dependent lensing leads naturally to unidirectional propagation for continuous-wave lasing.
