THE SPECIFIC FORCED RADIATION WAVE IMPEDANCE OF A FINITE RECTANGULAR PANEL EXCITED BY A PLANE SOUND WAVE

The average specific forced radiation wave impedance of a finite rectangular panel, excited by a plane sound wave incident at a particular angle of incidence, is of importance for the prediction of both sound insulation and sound absorption. In 1982, Thomasson published numerical calculations of the average specific forced radiation wave impedance of a square of side length 2e for wave number k for values of ke in half octave steps from 0.25 to 64. Thomasson also published approximate formulae for values of ke above and below the published results. This paper combines Thomasson's high and low frequency formulae and compares this combined formula with Thomasson's numerical calculations. The real part of the approximate formula is between 0.7 dB higher and -1 dB lower than the numerical calculations. The imaginary part of the approximate formula is between 2.3 dB higher and - 2.6 dB lower than the numerical calculations. These extreme differences occur in the region of ke equals 2. However the imaginary part also has a difference of 1.7 dB for ke equals 64 at an angle of incidence of the forcing wave of 60 degrees relative to the normal to the square panel. An approximate formula for the real part developed previously by Davy is between 0.4 dB higher and -0.6 dB lower than Thomasson's numerical calculations. Thus it is in slightly better agreement with Thomasson's numerical calculations than the formula obtained by combining Thomasson's high and low frequency approximations. The imaginary specific radiation impedance of a rigid disk of equal area to a square and vibrating in phase gives a good approximation, up to ke equals 5, to the imaginary part of the specific forced radiation impedance of a square which has been excited by a plane wave incident normally to the square.
Stakeholder consultations in the energy directorate : can they help integrate climate change?

Investigation of the conditions under which formal stakeholder consultations of the Directorate General Energy of the European Commission can help integrate climate change policy in energy policy in the European Union suggests that stakeholder consultations that aim at producing soft law and binding recommendations are rather insular, have low diversity of participants, and do not integrate climate change issues. Forums that aim at providing a discussion platform have higher diversity and integrate climate change issues to a certain extent. Stakeholder consultations can facilitate climate policy integration in European Union energy policy, as they take place early in the policy process. However, integration requires political commitment, and a concrete structure and format of the consultations that would facilitate integration.
Bioavailability of Two Oral Tablet Formulations of citalopram 20 mg: Single-Dose, Open-Label, Randomized, Two-Period Crossover Comparison in Healthy Mexican Adult Subjects

The aim of this study was to compare the bioavailab ility and determine the bioequivalence of one test formul ation (citalopram 20 mg oral tablet) with its correspondi ng list reference-drug formulation in Mexico. A single dose, randomized, open-label, 2-period cro ss- over, post-marketing study with a 2-weeks washout p e- riod between doses was conducted. Blood samples wer e drawn at baseline, 0.5, 1.0, 2.0, 3.0, 4.0, 5.0, 6. 0, 7.0, 8.0, 10.0, 12.0, 24.0, 48.0, 72.0, 96.0 y 120.0 hours af ter dos- ing. Citalopram plasma levels were determined using HPLC assay method. A total of 24 subjects were enrolled in the study. The bioequivalence test drug values were C max of 26.37 ng/ mL, t max of 3.76 h, AUC 0-t of 613.84 h.ng/mL, AUC 0- ∞ of 879.65 h. ng/mL, and reference drug values of C max of 25.50 ng/mL, t max of 3.96 h AUC 0-t of 596.65 h. ng/mL, AUC 0- ∞ of 982.38 h. ng/mL. No period or sequence effect w as observed. In this study in healthy Mexican adult subjects, a single dose of citalopram 20 mg of the test formulation wa s found to be bioequivalent to the corresponding reference formu- lation according to the regulatory definition of bioequivalence based on the rate and extent of abso rp- tion. Both formulations were generally well tolerat ed.
Unit Root Tests and Heavy‐Tailed Innovations

We evaluate the impact of heavy‐tailed innovations on some popular unit root tests. In the context of a near‐integrated series driven by linear process shocks, we demonstrate that their limiting distributions are altered under infinite variance vis‐à‐vis finite variance. Reassuringly, however, simulation results suggest that the impact of heavy‐tailed innovations on these tests is relatively small. We use the framework of Amsler and Schmidt ( ) whereby the innovations have local‐to‐finite variances being generated as a linear combination of draws from a thin‐tailed distribution (in the domain of attraction of the Gaussian distribution) and a heavy‐tailed distribution (in the normal domain of attraction of a stable law). We also explore the properties of augmented Dickey–Fuller tests that employ Eicker–White standard errors, demonstrating that these can yield significant power improvements over conventional tests.
Analysis of strawberry genes differentially expressed in response to Colletotrichum infection

Important losses in strawberry production are caused by species of the fungus Colletotrichum, the causal agent of anthracnose. However, very limited studies at molecular level exist of the mechanisms related to strawberry susceptibility against this pathogen. We have analysed a moderately resistant cultivar (cv. Andana) together with a very susceptible one (cv. Camarosa) during the process of infection with Colletotrichum acutatum at a molecular level. To gain insight into this interaction we have identified a large number of strawberry genes involved in signalling, transcriptional control, defence and many genes with unknown function with altered expression in response to C. acutatum infection. Spatial and temporal gene expression profiles after infection showed that the response was dependant on the tissue and cultivar analysed and also quicker and/or stronger in the moderately resistant cultivar (cv. Andana) than in the susceptible one (cv. Camarosa). Interestingly, we found that genes described as being induced during pathogen infection such as g-thionins, peroxidases, chitinases and b-1-3-glucanases were downregulated in fruit and/ or crown tissues of the very susceptible cultivar. Our results yielded a first insight on some of the genes responding to this plant–pathogen interaction at molecular level and suggest that pathogen progression can be dependent upon a reduction of the active defences of strawberry and this is genotype and tissue dependent.
Comparison of Postfire Soil Water Repellency Amelioration Strategies on Bluebunch Wheatgrass and Cheatgrass Survival

Abstract Soil water repellency can limit postfire reseeding efforts and thus increase the susceptibility of a site to weed invasion. We evaluated the effectiveness of wetting agents and simulated anchor chaining for improving seedling growth and survival in water-repellent soil, for the native perennial bluebunch wheatgrass (Pseudoroegneria spicata) and invasive annual cheatgrass (Bromus tectorum). Research was performed in a glasshouse, on 20-cm-diameter soil cores that were excavated from underneath burned Utah juniper (Juniperus osteosperma) trees. The experiment was arranged as a randomized split-plot design, with the two grass species sown separately under four soil treatments: 1) no treatment (control), 2) simulated anchor chaining (hereafter referred to as “till”), 3) wetting agent, and 4) till plus wetting agent. Soil water content was highest in the wetting agent treatment, lower for till, and lowest in the control. Overall, the response of bluebunch wheatgrass and cheatgrass was similar among treatments. At the conclusion of the study, wetting agent cores had twice as many seedlings as the control, while the till and control were similar. Despite a lower number of seedlings, tilling in general resulted in the same level of biomass as the wetting agent treatment. Overall, biomass in the till and wetting agent treatments was at least twofold higher than the control. No benefit was found in applying both till and wetting agent treatments together in comparison to just applying wetting agent. Because of a lack of correlation between glasshouse and field settings the results of this study need to be interpreted with caution. Our data may indicate that if cheatgrass is not already present on the site, anchor chaining or treating the soil with wetting agent can increase establishment of seeded species.
Temperature variations in the dayside magnetosheath and their dependence on ion‐scale magnetic structures: THEMIS statistics and measurements by MMS

The magnetosheath contains an array of waves, instabilities, and nonlinear magnetic structures which modify global plasma properties by means of various wave‐particle interactions. The present work demonstrates that ion‐scale magnetic field structures (∼0.2–0.5 Hz) observed in the dayside magnetosheath are statistically correlated to ion temperature changes on orders 10–20% of the background value. In addition, our statistical analysis implies that larger temperature changes are in equipartition to larger amplitude magnetic structures. This effect was more pronounced behind the quasi‐parallel bow shock and during faster solar wind speeds. The study of two separate intervals suggests that this effect can result from both local and external drivers. This manuscript presents two separate case studies, one from using THEMIS (Time History of Events and Macroscale Interactions during Substorms) data and another from Magnetospheric Multiscale; these measurements are then supported by extensive THEMIS statistical observations. These results could partly explain the 10–20% dawn‐favored asymmetry of the magnetosheath ion temperature seed population and contribute to the dawn‐favored asymmetry of cold component ions in the cold dense plasma sheet.
EVALUATION OF ANTIBACTERIAL ACTIVITY OF ENDOPHYTIC FUNGI ASPERGILLUS JAPONICUS ISOLATED FROM TRIDAX PROCUMBENS L.

Objective: The main purpose of the present study was to isolate the endophytic fungi from Tridax procumbens L. and evaluate their antibacterial activity at different concentration of compatible solvents extracted metabolites against the test pathogenic bacterial strain, as well as the molecular characterization of potent endophytic fungal isolate that showed the maximum antibacterial activity.Methods: The endophytic fungi were isolated from the different parts of the collected T. procumbens plant. Screening of endophytic fungi for the antibacterial activity was scrutinized against five pathogenic bacteria such as Bacillus subtilis, Streptococcus pyogenes, Escherichia coli, Klebsiella pneumoniae, and Salmonella typhimurium using agar well diffusion method. After screening, the metabolite of the potent fungal isolate was extracted using different solvents by solvent-solvent extraction procedure and observed their antibacterial activity. For molecular identification of the fungi, the DNA was extracted, quantified, and amplified using two oligonucleotide primers ITS4 and ITS6 in polymerase chain reaction.Results: In the present study, five endophytic fungi were isolated from medicinal plant T. procumbens and screened for their antibacterial activity against E. coli (22.60±0.32 mm), S. typhimurium (19.26±0.23 mm), S. pyogenes (16.36±0.18 mm), K. pneumoniae (14.26±0.54 mm), and B. subtilis (14.43±0.27 mm) bacterial strain. The endophytic fungal strain A. japonicus isolated from T. procumbens was showed the significant antibacterial activity against the pathogenic bacteria. The morphological identification of all the isolated endophytic fungi was observed on the basis of their macroscopic and microscopic characteristics, and the molecular identification of the potent fungal strain was observed through 18s rRNA sequence analysis. Using solvent-solvent extraction technique, different solvent residues of the potent fungal metabolite were extracted in benzene, n-,butanol and toluene. The n-butanol solvent extract exhibited a maximum zone of inhibition against the test bacterial strains.Conclusion: The present study reveals that the endophytic fungi serve as a potential source for the production of effective bioactive compounds.
The Impact of Land Conversion on Income and Food Security Status For Farmer Households in 5 Villages in Temon Sub-District, Kulon Progo District, 2017

Preparation for the construction and development of NYIA airport in Temon sub district, Kulon Progo district, D.I. Yogyakarta province has caused displacement of people for their land, including farmers. Farmers affected are located in five villages that include Jankaran, Palihan, Sindutan, Glagah and Kebon Rejo. The objective of this resrarch is to analyze the impact of land conversion on farmer household incomes and food security status. The research used both primary and secondary data. Primary data was collected using structured questionnaire. Analysis of data was based on descriptive statistics and test of differences between paired samples. Results showed that land conversion has had a negative and significant influence on incomes of affected farmer households. The decline in household income of farmers in 5 villages in Temon sub district among other factors, is attributable to the reduction in farming land. Secondly, consequently, loss of farmer household income aggravated the vulnerability of the affected households to food insecurity. The number of farmer households that experienced food insecurity increased from 87 percent of all farmer households prior to land conversion to 90 percent after land conversion. Conclusions formed the basis for several policy recommendations to mitigate and if possible overcome the problem.
Conflict in cross-functional teams: a practical case analysis

The present study is a qualitative analysis of the tensions that occur in cross-functional teams (CFTs) and the way in which they can affect the teams' accomplishments. The research is focused on a single case, COHTTEC 2005, a program aimed at transforming new technologies into businesses that took place in Lisbon, Portugal, starting March 2005. In this program, participants were organized in cross-functional teams that included researchers and management students. Semi-structured interviews were made to a sample of 17 participants. These interviews were recorded and transcribed. A table was then elaborated based on the primary data provided by the subjects and these data were classified in different categories. A three-stage model of group dynamics is proposed. The major findings of this project point to the role of interpersonal relationships on group outcomes. More specifically, several patterns associated with team malfunction were uncovered, the clearest ones being autocratic decision-making and arrogant behavior from some team members, as well as escalation in relationship conflict. Implications from these results are discussed, both for future research and for practice.
Looking Awkward when Winning and Foolish when Losing: Inequity Aversion and Performance in the Field

The experimental literature and studies using survey data have established that people care a great deal about their relative economic position and not solely, as standard economic theory assumes, about their absolute economic position. Individuals are concerned about social comparisons. However, behavioral evidence in the field is rare. This paper provides an empirical analysis testing the model of inequity aversion using two unique panel data sets for basketball and soccer players. We find support that the concept of inequity aversion helps to understand how the relative income situation affects performance in a real competitive environment with real tasks and real incentives.
Identification of inclusive education classroom teachers views and needs regarding ın-service training on special education in Turkey

The aim of the study is to identify the views and needs of classroom teachers providing inclusive education in Turkey regarding in-service training on special education. Research was conducted in Bolu Province of Turkey with 222 teachers. Identification Tool for Teachers’ In-Service Training Needs (ITTIST) developed for the current study was used in this research. Reliability and validity studies for ITTIST were undertaken as the first step followed by analysis of the scores obtained from the teachers based on ITTIST through descriptive analysis and one-way analysis of variance. Results showed that in-service training needs of inclusive education classroom teachers related to special education were at high levels. The study also presented teachers’ need for general knowledge about students with special educational needs (SEN), social skills training, use of least restrictive environments, and forming goals and assessment. Obtained results were discussed in terms of increasing teacher capacity in inclusive education practices. Key words: Inclusive education, in-service training, needs of teachers, teacher expectations, students with special needs.
CORPORATE GOVERNANCE AND TRANSACTION COST ECONOMICS: A STUDY OF THE EQUITY

This paper extends the Transaction Cost Economics (TCE) theory of the equity governance structure by introducing a (hitherto absent) full analysis of the key TCE issue of bilateral dependency between the firm and its shareholders. In addition, the paper discusses the implications of the analysis for the topic of corporate governance and firm performance. We find that when bilateral dependency holds contractual hazards are mitigated as predicted by TCE, but that when it does not contractual safeguards are altered to the disadvantage of shareholders and managerial discretion costs increase as reflected by lower firm valuation. Importantly, our study documents for the first time a class of transactions where business relationships persist indefinitely even though transaction costs are not minimized.
Fossil groups origins - I. RX J105453.3+552102 a very massive and relaxed system at z ~ 0.5

Context. The most accepted scenario for the origin of fossil groups is that they are galaxy associations in which the merging rate was fast and efficient. These systems have assembled half of their mass at early epoch of the Universe, subsequently growing by minor mergers, and therefore could contain a fossil record of the galaxy structure formation. Aims. We have started an observational project in order to characterize a large sample of fossil groups. In this paper we present the analysis of the fossil system RX J105453.3+552102. Methods. Optical deep images were used for studying the properties of the brightest group galaxy and for computing the photometric luminosity function of the group. We have also performed a detail dynamical analysis of the system based on redshift data for 116 galaxies. Combining galaxy velocities and positions we selected 78 group members.
Are living and non-living category-specific deficits causally linked to impaired perceptual or associative knowledge? evidence from a category-specific double dissociation

Abstract Perhaps the most influential view of category-specific deficits is one in which the dissociation between living and non-living kinds reflects differential reliance on, or weighting of visual or associative-functional attributes. We present data collected from two patients, which question the apparent relationship between category-specific deficits and loss of specific attribute types. One patient with dementia of Alzheimer's type presented with relatively poor performance on living things but failed to show a difference between knowledge of visual and associative-functional information. The other patient with semantic dementia demonstrated relatively poor knowledge of visual attributes but failed to exhibit a category-specific impairment for animate kinds. In fact her comprehension and naming were slightly but significantly better for living things. The data are discussed with reference to various theories of category-specific impairment. We suggest that category-specific deficits for living thin.
The Effects of Asthma on Academic Achievement in a Sample of Former Head Start Children

The ways in which a diagnosis of asthma can affect the academic achievement of students were examined in a sample of 5,711 former Head Start children, 788 of which were identified as having asthma. Â Results indicated statistically significant group differences in standardized reading and mathematics scores, with students with asthma performing worse than students without this diagnosis in both academic areas. Â In reference to reading abilities among students with asthma, indicators of socioeconomic status, gender, and level of school absences were found to be predictive of reading scores. Â Regarding mathematics abilities, results indicated the significant contribution of both socioeconomic status and level of school absences in predicting the math scores of students with asthma. Â Variables regarding the family environment did not make a significant contribution to explaining the asthma-academic achievement relationship beyond the effects of these variables.
Comparison of Four Different Irrigating Solutions on Dentinal Debris Removal

Aim: The aim of this research was to compare the dentinal debris removal capacity of 17% EDTA, 2.5% NaOCl, MTAD and 2% Clorhexidine when used as an irrigants throughout root canal instrumentation. Methodology: Eighty maxillary incisors were used and allocated into four groups and instrumented with the same clinical procedure but rinsed with a different irrigant solution. Results: Irrigating solutions employed were: 17% EDTA, MTAD, 2.5% NaOCl and 2% Clorhexidine. After irrigation with: EDTA and MTAD resulted in little debris residual on canals as related with NaOCl and Clorhexidine. NaOCl left little debris on canals as compared with Clorhexidine but the difference was not statistically major. The Q-Cochran test showed statistical significance among the four groups. As the results for each group did not follow a normal distribution, the variables were analyzed using a nonparametric test. The level of statistical significance was set at p<0.05. Conclusion: The final third of the canals revealed more debris than the two coronal canal and any of the irrigant employed left a clean canal in 100%.
A comparison of North American and West European oyster embryo-larval toxicity tests on North Sea sediments

During the Bremerhaven Workshop, Pacific oyster embryos Crassostrea gigas were exposed both directly to sediment and to elutriates of sediment from 2 transects through contamination gradients in the North Sea. One transect consisted of 7 stations down-current from an abandoned drilling site off the Dutch coast. The other transect comprised 9 stations in the German Bight positioned in a northwesterly direction from the Elbe-Weser plume out to the Dogger Bank. The toxicity tests, conducted by 4 research laboratories, were carned out either immediately following sediment sampling on board a research vessel, or after periods of up to 4 wk after sediment collection at mainland laboratories in the UK, Canada and The Netherlands. Oyster embryo-larval sediment elutriate tests showed highest levels of tox~city at the most contaminated sites on the German Bight transect, but data were not consistent on the drill~ng site transect. The optimal method of sediment elutriation should be determined by further studies. Oyster embryos exposed directly to sediment over a 48 h period identified the most toxic and contaminated sites from both transects and gave comparable results to infaunal amphipod acute toxicity tests. This study has demonstrated that oyster embryo-larval tests can easily be carried out on board a sea-going research vessel, although there is no absolute requirement to do so when sediment samples can be returned to mainland laboratories within a few days after collection.
