Archaeoacoustic Analysis of an Ancient Hypogeum in Italy

Abstract The archaeoacoustic properties of an ancient hypogeum in Cividale del Friuli (North Italy) were studied. A series of experiments took place over a one year period to establish its acoustical resonant properties. A number of male and female singers were used and a resonance of 94Hz and 103Hz was discovered in two of the hypogeum’s six chambers. The best frequency response was obtained when male singers were positioned inside a ‘sound node’ that was discovered in both chambers. The term "node" refers to the point in the interior space of the chamber where the greatest acoustic resonance effect is achieved. Later the effects of a frame drum were studied in one of the two chambers. Although it had an average frequency response of 55Hz, the drum was able to activate the chambers resonance of 103Hz from its harmonics. The research demonstrated the male voice was more successful in stimulating the resonance than a female voice, as the required resonant frequencies commonly fall within the male vocal range. This study demonstrates that archaeoacoustics is an interesting emerging field capable of analyzing ancient sites, utilizing different study parameters to those usually used in archaeology. Research in this field is re-discovering lost technology that operates on the human emotional sphere.
On the structure of almost einstein manifolds

In this paper, we study the structure of the limit space of a sequence of almost Einstein manifolds, which are generalizations of Einstein manifolds. Roughly speaking, such manifolds are the initial manifolds of some normalized Ricci flows whose scalar curvatures are almost constants over space-time in the L1-sense, Ricci curvatures are bounded from below at the initial time. Under the non-collapsed condition, we show that the limit space of a sequence of almost Einstein manifolds has most properties which is known for the limit space of Einstein manifolds. As applications, we can apply our structure results to study the properties of Kahler manifolds.
Assessment of Water Quality Index of Borehole and Well Water in Wukari Town, Taraba State, Nigeria

Water samples collected from boreholes and hand dug wells located in two wards in Wukari town were assessedfor some physico-chemical parameters on collection and after one week of storage using standard analyticalmethods. Furthermore the quality indices were determined for the water samples on collection and after oneweek of storage. The parameters determined include temperature, turbidity, suspended solids, total dissolvedsolids, conductivity, pH, nitrate –nitrogen, phosphates, chlorides, alkalinity, COD and DO. The result showedthat some parameters like turbidity, conductivity and suspended solids exhibited a marked drop in valuefollowing their storage for one week in both borehole and hand dug well water samples. Mean values ofparameters like nitrate-nitrogen, phosphates and chlorides did not exhibit marked drop in concentration values inboth water sources. Turbidity and suspended solid values in the well water samples was more than that ofborehole waters however the mean conductivity values in borehole water is more than in well water. Water fromboth sources was found to exhibit hardness on collection and after one week of storage. The quality indices inborehole and well water on collection were found to be 26 and 136 respectively. After one week of storage thequality indices were determined and the values were found to be 15 and 89 respectively indicating improvementin the water quality after storage for one week. Borehole water in Wukari was found to possess better quality fordrinking than well water. The study provides baseline information on the quality of borehole and hand dug wellwaters in Wukari Town. In addition, the hardness of the water sources may be an indication of the presence ofunderlying minerals in the ground. Keywords : Borehole, hand dug well, storage,water quality index
Stability of Recombinant Proteins in Escherichia coli: The Effect of Co-Expression of Five Different Chaperone Sets

Chaperones are produced by prokaryotic, yeast and higher eukaryotic cells for various purposes. Over-expression of each chaperone or sets of them affect the production level of a recombinant protein in the cell. On the basis of this hypothesis, five different plasmids with 5 different combinations of 6 chaperones molecule, transformed into Escherichia coli along with human basic Fibroblast Growth Factor expression plasmid. Each transformant that contain both plasmids for expression of hbFGF and chaperone combinations was induced with proper concentration of related inducers. Subsequently, total amount of produced hbFGF was analyzed b ased on SDS-PAGE and ELISA. O ur results indicated that “ TF” and “DnaK/DnaJ/GrpE” destabilized hbFGF, while “DnaK/DnaJ/GrpE/GroEL /GroES” and “GroEL/GroES” combinations were able to stabilize it. It has also revealed that “GroEL/GroES/TF” combination negatively affected the hbFGF production.

Therefore, the results of electronic customer relationship management performance are repeat purchase, word of mouth, retention, cross buying, brand loyalty and customer satisfaction. The keen competitive in the communication and mobile phone service market place and the increasing numbers of mobile phone users all over the world has influence the researcher to investigate usability and enjoyment as antecedents of electronic customer relationship management performance in mobile phone services industry. Four hundreds and eighty eight set of questionnaires have returned and analyzed. Two factors been tested to investigate the relationship with E-CRM performance. The analysis shows that usability was positively significant towards E-CRM performance. Enjoyment has failed to predict E-CRM performance. Base on the results, it can be concluded that the mobile service provider has to ensure their services fully satisfied their customer usability. Somehow, future research must investigate other factors as the antecedent for E-CRM performance. Other initiative is to consider a model testing in difference context of electronic service to see any generalization on the research result.
Review of peat strength, peat characterisation and constitutive modelling of peat with reference to landslides

Resume: On a etabli les courbes de compressibilite et de resistance et de deformation a la rupture en fonction du confinement pour des roches tres diverses (gaizes, calcaires, marbres, gres.). Sur ces 3 types de courbes on met en evidence 5 pressions de confinement particulieres: P0 (pression de fermeture), Pt (pression de transition), Pc (pression de consolidation), Pd (pression de pleine ductilite) et Pf (pression de changement de phase). Les valeurs de chacune de ces pressions sont differentes en fonction du type de roche. Dans certains cas, ces pressions peuvent etre interpretees par rapport a la structure intime des materiaux: pour un grand nombre de roches P0 est interprete classiquement comme la fermeture des cracks; Pt correspond a la transition fragile–ductile; dans les gaizes, Pc correspond a la combinaison de la rupture fragile de certains mineraux et de la deformation plastique de certains autres, conduisant au collapse des pores; Pd peut s’expliquer par la rupture soit cataclastique soit ductile des grains, les 2 conduisant a la pleine ductilite a l’echelle de l’echantillon; Pf peut correspondre dans les carbonates au changement de phase calcite–aragonite. Cependant sur les gres de Tumlin nous montrons que P0 ne correspond pas a la fermeture de fissures mais a l’ecrasement de particules d’argiles intergranulaires. On est donc conduit a proposer que chacune de ces pressions remarquables correspond a des mecanismes intimes differents selon la roche concernee.
NHANCEMENT OF OBLIQUE EFFECT IN THE CAT ’ S PRIMARY ISUAL CORTEX VIA ORIENTATION PREFERENCE SHIFTING NDUCED BY EXCITATORY FEEDBACK FROM HIGHER-ORDER ORTICAL AREA 21 A

bstract—It is often suggested that the oblique effect, the ell-known phenomenon whereby both humans and animals re visually more sensitive to vertical and horizontal conours than to oblique ones, is due to the overrepresentation f cardinal orientations in the visual cortex. The functional role f feedback projections from higher-order cortical areas to lowr-order areas is not fully understood. Combining the two isues in a study using optical imaging here, we report that the eural oblique effect was significantly enhanced (3.7 times igher than the normal) in the cat’s primary visual cortex hrough orientation shifting induced by excitatory feedback rom the higher-order cortical area 21a. This suggests that a eciprocal co-excitatory mechanism may underlie the percepual oblique effect. © 2006 IBRO. Published by Elsevier Ltd. ll rights reserved.

Physico Chemical, Antioxidant and Pasting Properties of Pre-heated Purple Sweet Potato Flour

Purple sweet potatoes contain anthocyanins which could function as a natural food colorant, and an antioxidant. One of the problems in handling the fresh roots is their susceptibility during storage, and to extend their uses, fresh purple sweet potato could be processed into flour. However, during flouring process, the properties of the purple sweet potato may undergo some changes such as partial gelatinization of the starch and discolorization. Therefore, the purpose of this study was to investigate the effect of pre-heating treatment during flouring process on degree of gelatinization, the anthocyanin content, the antioxidant activity and the total phenolic content of heat treated purple sweet potato flour. Other objectives were to observed the changes in the starch properties such as rheological properties, granular appearance of the heat treated- purple sweet potato flour. Pre-heating treatment of purple sweet potato flour was prepared by heating grated purple sweet potato in a single rotary drum cooker at 90°C for 15, 30, 45, 60 and 75 min, followed by drying in a cabinet dryer at 60°C for 8 h. The results showed the longer pre-heating time at 90°C had caused increase in the degree of gelatinization, increase in total phenolic and anthocyanin retention. In addition, differences in gelatinization temperature, maximum viscosity, paste stability and retrogradation, and differences in scanning electron microscope (SEM) of granular appearance were also observed. The overall results indicated that pre-heating treatment can be used for modifying the physical, chemical and rheological properties to suit various applications and preserving functional properties of purple sweet potato flour.
Removal of Methylene Blue Dye by Using Eggshell Powder

Dyes contain carcinogenic materials which can cause serious hazards to aquatic life and the users of water. Textile industry is the main source of dye wastewater which results in environmental pollution. Many studies have been conducted to investigate the use of low cost adsorbent as an alternative technique for the adsorption of dye. The objective of this study is to determine the potential of eggshell powder as an adsorbent for methylene blue removal and find out the best operating conditions for the color adsorption at laboratory scale. The adsorption of cationic methylene blue from aqueous solution onto the eggshell powder was carried out by varying the operating parameters which were contact time, pH, dosage of eggshell powder and temperature in order to study their effect in adsorption capacity of eggshell powder. The results obtained showed that the best operating condition for removal of methylene blue was at pH 10 (78.98 %) and temperature 50°C (47.37 %) by using 2 g of eggshell powder (57.03 %) with 30 minutes equilibrium time (41.36 %). The kinetic studies indicated that pseudo-second-order model best described the adsorption process.
The Long-Run Stock Performance of Privatization IPOs

This paper compares the long-run buy-and-hold returns of privatization initial public offerings (IPOs) to those of the domestic stock markets of respective countries using a sample of 241 privatization IPOs from 41 countries. The evidence indicates that the privatization IPOs significantly outperform their domestic stock markets if the returns are equally-weighted while value-weighted returns show a sharp reduction in performance. However, there are substantial variations in the long-run performance of privatization IPOs across industries, issuing countries, issue period, and the origin of commercial law of the country. This paper also analyzes the cross-sectional determinants of the long-run buy-and-hold returns of privatization shares. The results indicate that the long-run performance of privatization IPOs is significantly related to the proxies of policy uncertainty, consistent with the signaling models of Perotti (1995). Such effects appear to be overwhelming in the earlier post-IPO period, while the traditional market factors become more important as the policy uncertainty disappears over time. The institutional features of the country such as accounting standards, origin of commercial law, and corporate governance scheme also affect the return performance of privatization issues.
Indications for sexology consultation in women after surgical treatment due to breast cancer.

INTRODUCTION AND OBJECTIVES Surgical treatment due to brest cancer have an impact on women sexuality. There is a need for research about effective indications for sexology consultation in women after such treatment. The aim of this study is to determine the indications for sexology consultation in women after surgical treatment for breast cancer. MATERIAL AND METHODS We tested 42 women patients diagnosed with breast cancer who had undergone mastectomy 3 months before the study. 3 months after the surgery the women were surveyed using the Polish version of FSFI assessing sexual functioning in women. The result of PL-FSFI were compared with the control group. RESULTS It was found that the mean score of PL-FSFI in the study group 3 months after the surgery was 13.33 points (score range: 1.2-31.7; median 8.3 points) with a statistically significant difference in terms of areas: desire, arousal, lubrication and orgasm in favour of the control group. The total score of PL-FSFI was significantly lower in women after mastectomy than in women after breast-conserving surgery. It has been shown that sexually active women in whom the surgery concerned the right breast (on the side of the dominant hand) scored lower on the scale "sexual functioning" of QLQ-BR-23 than women with surgery of the left breast, with this difference being statistically significant. There was a statistically significant correlation between the baseline performance status on the Zubrod scale and the scales: desire, lubrication and satisfaction of PL-FSFI. Living in a small town proved to be statistically significant for predicting a lower risk of sexual dysfunction among the surveyed women. CONCLUSIONS The women who underwent surgery due to breast cancer had a higher risk of sexual dysfunction compared to the general population. Higher risk of sexual dysfunction especially concerns women after mastectomy, those who underwent breast surgery on the side of the dominant hand, and those with a worse preoperative overall level of functioning of > = 1 point on the Zubrod scale. A lower risk of disorders was observed in women living in smaller towns. The above factors indicate the advisability for sexology consultation in women with breast cancer.
Awareness of reading strategy use and reading comprehension among poor and good readers

The present study was designed to explore the primary school students' awareness of reading strategies and to identify possible differences between poor and good readers, in terms of frequency and efficiency. Furthermore, it aimed at exploring the relation between reading strategy awareness and reading comprehension. Eighteen poor readers and eighteen good readers, aged between 11 and 12, which were selected from a total of 201 sixth grade students, participated in the study. The study was conducted by using retrospective interviews as the basic instrument, in combination with reading test scores. Both groups utilized a variety of cognitive strategies, though it was revealed that poor readers, on the one hand, were less aware of the more sophisticated cognitive strategies, and on the other hand they reported a limited number of metacognitive strategies in comparison with good readers. In addition, both cognitive and metacognitive strategy awareness made a unique contribution to reading comprehension, beyond and above the effects of reading accuracy and reading speed.
Relationship Between Foreign Language Listening Anxiety and Listening Comprehension

This study was carried out to investigate the relationship between foreign language listening anxiety and listening comprehension. The study employed correlational study design. Participants of the study were 40 grade 11 students who attended the listening class in 2015/2016. Foreign language listening anxiety questionnaire and listening comprehension tests were used as data gathering instruments. These data were analyzed using Pearson’s Product moment correlation and one way ANOVA. In order to identify the significance of differences between the pairs of FL listening anxiety, multiple comparisons or a post hoc test was also conducted. The results revealed that there was a significant, negative correlation between listening comprehension and foreign language listening anxiety. The findings also showed that the mean differences were statistically significant between the low anxiety and average anxiety, low anxiety and high anxiety and average anxiety and high anxiety.
Testing the Dynamic Trade-off Theory of Capital Structure: An Empirical Analysis

We employ a new empirical approach based on dynamic threshold partial adjustment models to study the asymmetry in firms’ adjustment towards their target leverage ratios. We examine several factors proxying for differential costs of adjustment that may lead to the heterogeneity in the speed with which firms adjust their capital structure. Using an unbalanced panel of UK firms, we find that firms having high dividend payments, large investment, high profitability, high growth opportunities, or a large deviation from their target leverage have slower speeds of adjustment than those with the opposite characteristics. We further observe a consistent pattern that firms move towards target leverage quickly when they are over-levered, possibly to avoid the large financial distress associated with having above-target leverage. Taken together, our results provide strong empirical support for the dynamic trade-off theory. JEL Classification: G32.
Online retail returns management: Integration within an omni-channel distribution context

Purpose – With the rapid growth of consumer sales being fulfilled through omni-channel retailing, the purpose of this paper is to explore the subsequent impact on the levels of consumer retail returns experienced through online sales and the emergent returns management strategies being affected by retailers in relation to network configuration and returns management processes. Design/methodology/approach – The authors uses a mixed methods approach from an interpretive perspective. It is appropriate to describe the approach in terms of convergent design, since the authors have collected both qualitative and quantitative data. Findings – Return rates for online retailing can be double those for stores, while return levels for “considered purchases” remain similar. The findings suggest that omni-channel returns management has yet to fully mature and the authors find challenges for network design and returns processes in offering a seamless solution. Research limitations/implications – For practitioners the a.
The Mediating Role of Job Characteristics in the Relationship between Organizational Commitment and Job Satisfaction

The study aims at examining the influence of organizational commitment on job characteristics and job satisfaction. Moreover, it aims at investigating the influence of job characteristics and job satisfaction. A random sample was selected from non-managerial employees working at three malls in Amman, the capital city of Jordan. It consists of 750 participants. A total of 731 questionnaires were completed and returned. The results supported the hypothesized paths among constructs. As such, there is a significant and positive influence of organizational commitment on job characteristics and job satisfaction. Additionally, there is a significant and positive influence of job characteristics and job satisfaction. Hence, malls in Jordan should pay more attention to organizational commitment since it increases job satisfaction and improves job characteristics from the employees’ perspective. This research paper contributes to job satisfaction literature; job satisfaction should be enhanced by organizational commitment and job characteristics.
