The Middle Palaeolithic occupation of Mar-Tarik, a new Zagros Mousterian site in Bisotun Massif (Kermanshah, Iran)

La premiere campagne de terrain de la mission franco-iranienne portant sur le Paleolithique a concerne une cavite perchee du massif de Bisotoun, region de Kermanshah (sud du Zagros, Iran) decouverte en 1986. Les sept premiers cosignataires ont participe a la phase terrain (2004) qui a consiste en une etude globale et interdisciplinaire de la petite grotte de Mar Tarik dont le remplissage avait ete malheureusement affecte par des travaux clandestins qui ont detruit l'essentiel du gisement a l'exception de lambeaux de sediments indures et conserves dans la salle du fond. Outre des temoignages de frequentation ou d'occupations d'âge historique, protohistorique (Chalcolithique) qui ne sont pas decrits ici, les vestiges paleolithiques revelent une homogeneite evidente, concernant uniquement (ou presque) le Mousterien du Zagros. Une datation U/Th d'un speleotheme anterieur au niveau mousterien a ete rapporte au Dernier interglaciaire (OIS 5e). Il est possible de distinguer la faune post-paleolithique des vestiges pleistocenes par leur etat de surface mais sans contexte stratigraphique et avec un faible echantillonnage, l'histoire des differents stocks de faune, qui est complexe, n'est pas aisee a etablir. De meme pour les restes humains attribuables a Homo sapiens sp. Un essai de datation 14C SMA sur un fragment d'os humain insuffisamment riche en collagene n'a pas donne d'estimation chronologique. L'industrie lithique montre une chaine operatoire fractionnee typique d'un site de consommation secondaire avec faible activite de taille et importation d'outils deja prepares, les outils retouches representant 44 % du total de l'industrie. La production est dominee par la methode Levallois, difficile a identifier en cas de ravivages multiples. Les outils retouches sont typiques du Mousterien du Zagros: racloirs, racloirs dejetes, convergents, pointes, outils a dos amincis. Une pierre en calcaire fin est gravee de lignes ou quadrillages geometriques, mais, sans provenance stratigraphique claire, son appartenance au Mousterien, bien que possible, n'est pas assuree.

Numerical Estimation of Torsional Dynamic Coefficients of a Hydraulic Turbine

The rotordynamic behavior of a hydraulic turbine is influenced by fluid-rotor interactions at the turbine runner. In this paper computational fluid dynamics (CFDs) are used to numerically predict the torsional dynamic coefficients due to added polar inertia, damping, and stiffness of a Kaplan turbine runner. The simulations are carried out for three operating conditions, one at about 35% load, one at about 60% load (near best efficiency), and one at about 70% load. The runner rotational speed is perturbed with a sinusoidal function with different frequencies in order to estimate the coefficients of added polar inertia and damping. It is shown that the added coefficients are dependent of the load and the oscillation frequency of the runner. This affect the system's eigenfrequencies and damping. The eigenfrequency is reduced with up to 65% compared to the eigenfrequency of the mechanical system without the fluid interaction. The contribution to the damping ratio varies between 30–80% depending on the load. Hence, it is important to consider these added coefficients while carrying out dynamic analysis of the mechanical system.

Nutrition is a major factor that has an important role in the growth and development in the toddlers. In the nutritional fulfillment of the toddler, the mother plays very important role. This study aimed to determine the factors associated with the behavior of parents with the nutritional status of toddlers. The research design was used analytical survey with cross sectional study approach. The population in this research was 213 Balita, the sample in this research was 136 children in Bulalo Village Kwandang District, North Gorontalo District, the sampling method was used purposive sampling technique. Data collection of respondents in general using questionnaires, data analysis using SPSS program version 21.0. Bivariate analysis to know the existence of relation between dependent variable and independet by using chi squared test α = 0,05. The results showed that there was a correlation between parents' knowledge on the Nutritional Status of Toddlers (p = 0,000), there was a correlation between parental attitudes with the nutritional status in the toddler (p = 0,000), there was a correlation between parental action with the nutritional status in the toddler (p = 0,000 ). This study recommends to parents to always pay attention to the type of food consumed and the mothers should often follow the counseling done by midwives and nutrition officials so that the nutritional status of toddlers has increased.
Giant molecular filaments in the Milky Way

Throughout the Milky Way, molecular clouds typically appear filamentary, and mounting evidence indicates that this morphology plays an important role in star formation. What is not known is to what extent the dense filaments most closely associated with star formation are connected to the surrounding diffuse clouds up to arbitrarily large scales. How are these cradles of star formation linked to the Milky Way’s spiral structure? Using archival Galactic plane survey data, we have used multiple datasets in search of large-scale, velocity-coherent filaments in the Galactic plane. In this paper, we present our methods employed to identify coherent filamentary structures first in extinction and confirmed using Galactic Ring Survey data. We present a sample of seven giant molecular filaments (GMFs) that have lengths on the order of ~100 pc, total masses of 104–105 M⊙, and exhibit velocity coherence over their full length. The GMFs we study appear to be inter-arm clouds and may be the Milky Way analogs to spurs observed in nearby spiral galaxies. We find that between 2 and 12% of the total mass (above ~1020 cm-2) is “dense” (above 1022 cm-2), where filaments near spiral arms in the Galactic midplane tend to have higher dense gas mass fractions than those further from the arms.
On impulse excitation of the global poloidal modes in the magnetosphere

Abstract. Through the combined action of the field line curvature and finite plasma pressure in some regions of the magnetosphere (plasmapause, ring current) there can exist global poloidal Alfven modes standing both along field lines and across magnetic shells and propagating along azimuth. In this paper we investigate the spatio-temporal structure of such waves generated by an impulsive source. In general, the mode is the sum of radial harmonics whose structure is described by Hermitian polynomials. For the usually observed second harmonic structure along the background field, frequencies of these radial harmonics are very close to each other; therefore, the generated wave is almost a monochromatic oscillation. But mixing of the harmonics with different radial structure causes the evolution of the initially poloidal wave into the toroidal one. This casts some doubts upon the interpretation of observed high-m poloidal waves as global poloidal modes.
Characterization of liposomes and their effect on the properties of Cheddar cheese during ripening

This study was undertaken to observe the location and structure of liposomes in the cheese matrix and to identify their effect on the characteristics of Cheddar cheese during ripening. Com- position, proteolysis, microstructure and texture of Cheddar cheeses treated with either empty lipo- somes or liposomes containing cell-free extracts of Lactobacillus casei ssp. pseudoplantarum were ana- Iysed during two months of ripening. Results were compared with control Cheddar cheeses. Observations on cheese microstructure showed that sorne liposomes were included in the casein matrix, but most vesicles were located in areas close to fat globules and appeared destabilized as early as the first day after manufacture, inducing sorne changes in the cheese microstructure. The pre- sence of liposomes greatly increased the moisture of cheeses, modified the microstructure and the rheo- logical characteristics of ripened cheese. Cheeses containing liposomes were softer, less cohesive and elastic and more brittle than control cheeses. After two weeks of ripening and until the end of the study, proteolysis, particularly peptidolysis, was higher in cheeses treated with liposomes containing cell- free extracts. HPLC-analysis confirmed intensive peptidolysis between one and two months of ripe- ning. © InralElsevier, Paris liposome / cheese / microstructure / ripening
The cohomology of presheaves of algebras. I. Presheaves over a partially ordered set

To each presheaf (over a poset) of associative algebras A we associate an algebra A! We define a full exact embedding of the category of (presheaf) A-bimodules in that of A! -bimodules. We show that this embedding preserves neither enough (relative) injectives nor enough (relative) projectives, but nonetheless preserves (relative) Yoneda cohomology. The cohomology isomorphism links the deformations of manifolds, algebraic presheaves, and algebras. It also implies that the cohomology of any triangulable space is isomorphic to the Hochschild cohomology of an associative algebra. (The latter isomorphism preserves all known cohomology operations.) We conclude the paper by exhibiting for each associative algebra and triangulable space a "product" which is again an associative algebra. 0. Introduction. Presheaves are rather familiar objects and arise in many situations, some of which are discussed below. Our primary purpose in this paper is to prove a theorem which reduces questions about the cohomology of presheaves of rings to questions about the (classical) cohomology of rings. Specifically, fix a commutative ring k and a partially ordered set (poset) JY. Let A be a presheaf of associative k-algebras over >J hereinafter: a diagram. Then A has naturally associated with it an abelian category of bimodules and a (relative) Yoneda Cohomology bifunctor Ext*A(-,-). (All the foregoing formalism is introduced in ? 1.) We define for each such diagram A a single k-algebra A! and a full exact embedding, M M! , of the category of A-bimodules in the category of A! -bimodules (? 2). The embedding induces a natural transformation of Yoneda cohomology bifunctors, w*: ExtA (-, -) ! A Ext l (-! ,-! ) (? 2). Our central result is the Special Cohomology Comparison Theorem (CCT), namely: for an arbitrary diagram A over an arbitrary poset w*: ExtA (-,-) * ExtA , H _(-! -! ) is an isomorphism. The proof occupies ? 3, 4. The scheme of the proof will be given shortly. First we describe some of the history and utility of the CCT. In [GS1] we proved a "primitive" version of the CCT, applicable to arbitrary diagrams defined over arbitrary finite posets and to a narrow class of diagrams defined over a limited class of infinite posets.

Stock Price Response to Earnings Announcements: Evidence From the Nigerian Stock Market

The author examines the stock market reaction to annual earnings information releases using data for a sample of firms on the Nigerian Stock Exchange. Using the event study method, the author found that the magnitude of the cumulative abnormal returns is dominated by significant reactions 20 days before the earnings release date, which suggests that a portion of the market reaction may be due to private acquisition and, possibly, abuse of information by insiders. The persistent downward drift of the cumulative abnormal returns, 20 days after the announcement, is inconsistent with the efficient markets hypothesis.
Return intentions over the life course: Evidence on the effects of life events from a longitudinal sample of first- and second-generation Turkish migrants in Germany

Background: Although a growing body of migration literature has focused on the determinants of migrants’ plans to return to the home country, the role major life events play in return migration intention – including transitions and turning points, key concepts of the life course approach – has barely been examined. Objective: We address the following research question: What are the effects of family, work, and health events on the return intentions of first- and second-generation Turks living in Germany? Methods: We answer this research question using longitudinal data of first- and second-generation Turkish migrants who participated in the German Socio-Economic Panel (GSOEP) study between 1984 and 2012. Results: The results for first-generation Turkish migrants show that entering the empty-nest stage, becoming unemployed, and becoming employed in Germany increase the likelihood of intending to return, while partnership dissolution and childbirth act as a deterrent. Partnership formation, entering retirement, and health deterioration neither trigger nor deter the intention to return. For the second generation, becoming unemployed increases the intention to return, while partnership formation has the opposite effect. Partnership dissolution, childbirth, becoming employed in Germany, and health deterioration have no impact on the likelihood of intending to return. Conclusions: Our study shows that a number of key life events are important triggers of international relocation, although differences emerge when comparing first- and second-generation migrants. Further research could reveal whether these results are specific to the Turkish community. Contribution: The paper proposes several ways in which the life course approach could be developed in return migration research. It is also one of the first attempts to quantitatively assess the role of crucial life events in the family, work, and health domains in the return decision-making process of non-Western first- and second-generation migrants.
Effects of acute normovolemic hemodilution on healing of gastric anastomosis in rats

Purpose Acute normovolemic hemodilution (ANH) is an autologous transfusion method, using blood collected during surgery, to reduce the need for allogeneic blood transfusion. ANH is controversial because it may lead to various complications. Among the possible complications, anastomotic leakage is one that would have a significant effect on the operation outcome. However, the relationship between ANH and anastomotic site healing requires additional research. Therefore, we conducted this prospective study of ANH, comparing it with standard intraoperative management, undergoing gastric anastomosis in rats. Methods Sixteen Sprague-Dawley rats were randomly assigned to three groups: group A, surgery with ANH; group N, surgery with standard intraoperative management; and group C, sham surgery with standard intraoperative management. ANH was performed in group A animals by, removing 5.8–6.6 mL of blood and replacing it with 3 times as much crystalloid. All rats were enthanized on postoperative day 6, and histopathologic analyses were performed. Results The mean hematocrit values, after hemodilution were 22.0% (range, 18.0%–29.0%), group A; 33.0% (29.0%–35.0%), group N; and 32.5% (29.0%–34.0%), group C. There were significant differences between groups A and N (P = 0.019, P = 0.009, P = 0.004, P = 0.039, and P = 0.027), and between groups N and C (P = 0.006, P = 0.027, P = 0.04, P = 0.008, and P = 0.009) with respect to inflammatory cell numbers, neovascularization, fibroblast numbers, edema and necrosis, respectively; there were no differences between groups A and N. Conclusion In rat model, anastomotic complications did not increase in the ANH group, compared with the standard intraoperative management group.
Tax Mix Corners and Other Kinks

This paper models the local tax mix determination process in the presence of statewide fiscal limitations—the decentralized government finance archetype—and shows how excess sensitivity of local public spending to grants (the conventionally and somewhat misleadingly termed “flypaper effect”) arises in the constrained tax mix irrespective of whether lower or upper limits bind and how it cannot, in general, be taken as a symptom of local government overspending. An empirical application to Italian province panel data provides consistent evidence of the role of corner solutions produced by two-sided tax limits in explaining the sensitivity of local public expenditures to grants.
Are antibiotics still the same " Wonder Drugs " they used to be , or will increasing resistance render them useless ?

Bacterial infections had been a deadly disease for centuries before antibiotics were first discovered. Since then, antibiotics have brought an era of prosperity in medical field, saving millions of lives. However, our life-saving Wonder Drugs (Antibiotics) are being horrendously threatened by the growing number of resistance bacteria. Meaning, our antibiotics are losing their effectiveness, which in turn could cast us to the dark ages of medicine. Nowadays, Cancer is believed to be the deadliest disease in the world; however, statistics prove that by 2050, this world record would be broken by AMR (antimicrobial resistance) with 10 million deaths annually. Meanwhile, the goal of this project is to fully examine data and statistics available in detail, to reveal the seriousness of antibiotic resistance, if they are still as effective as they used to be and if there is any hope in saving the future of our Wonder Drugs. In order to find a valid answer to our title question, I have collected data from various resources, including books, review papers, Journals papers, conference Proceedings, the NHS and reports published by World Health Organisation (WHO). Furthermore, I have run an online survey to collect data on peoples‘ awareness towards antibiotics resistance. This is to prove, whether antibiotics will one day be defeated by the growing resistant bacteria or will they remain as effective as they have always
APPLICATION OF THE AQUATIC INDIGENOUS PLANTMATERIAL COAGULANTS FOR WASTE WATER TREATMENT

Laboratory scale experiments were carried out to study the effectiveness of plant materials, viz. Polygonum sps, Typha sps, Limnophyton sps, Commelina sps and Ipomoea sps towards removal of hazardous components including certain important Physico-chemical parameters of contaminated Water. The polluted water when treated with the plants extracts selected for the study removed turbidity upto 97 % following Coagulation-flocculation process. Maximum turbidity from the polluted water was removed by Typha sps.The pH of water tends to be neutral, the most suitable pH for drinking water which was slightly acidic before treatment with plant extracts. The wastewater revealed better Conductivity results after the treatment. Simultaneously, amount of solid waste get decreased, making the water more potable. Aquatic plants thus act as the best natural coagulants, thereby reducing the level of contaminants from the polluted water. Also, other natural bodies which are used by the rural people for domestic purposes can be purified by implementing this cost effective and ecofriendly technology.
SOX after Ten Years: A Multidisciplinary Review

SYNOPSIS: We review and assess research findings from more than 120 papers in accounting, finance, and law to evaluate the impact of the Sarbanes-Oxley Act. We describe significant developments in how the Act was implemented and find that despite severe criticism, the Act and institutions it created have survived almost intact since enactment. We report survey findings from informed parties that suggest that the Act has produced financial reporting benefits. While the direct costs of the Act were substantial and fell disproportionately on smaller companies, costs have fallen over time and in response to changes in its implementation. Research about indirect costs such as loss of risk taking in the U.S. is inconclusive. The evidence for and social welfare implications of claimed effects such as fewer IPOs or loss of foreign listings are unclear. Financial reporting quality appears to have gone up after SOX but research on causal attribution is weak. On balance, research on the Act's net social welfare rem.
Detailed chemical abundance analysis of the thick disk star cluster Gaia 1

Star clusters, particularly those objects in the disk-bulge-halo interface are as of yet poorly charted, albeit carrying important information about the formation and the structure of the Milky Way. Here, we present a detailed chemical abundance study of the recently discovered object Gaia 1. Photometry has previously suggested it as an intermediate-age, moderately metal-rich system, although the exact values for its age and metallicity remained ambiguous in the literature. We measured detailed chemical abundances of 14 elements in four red giant members, from high-resolution (R=25000) spectra that firmly establish Gaia 1 as an object associated with the thick disk. The resulting mean Fe abundance is $-0.62\pm$0.03(stat.)$\pm$0.10(sys.) dex, which is more metal-poor than indicated by previous spectroscopy from the literature, but it is fully in line with values from isochrone fitting. We find that Gaia 1 is moderately enhanced in the $\alpha$-elements, which allowed us to consolidate its membership with the thick disk via chemical tagging. The cluster's Fe-peak and neutron-capture elements are similar to those found across the metal-rich disks, where the latter indicate some level of $s$-process activity. No significant spread in iron nor in other heavy elements was detected, whereas we find evidence of light-element variations in Na, Mg, and Al. Nonetheless, the traditional Na-O and Mg-Al (anti-)correlations, typically seen in old globular clusters, are not seen in our data. This confirms that Gaia 1 is rather a massive and luminous open cluster than a low-mass globular cluster. Finally, orbital computations of the target stars bolster our chemical findings of Gaia 1's present-day membership with the thick disk, even though it remains unclear, which mechanisms put it in that place.
Impact of Openness, Foreign Direct Investment, Gross Capital Formation on Economic Growth in Kenya

The general objective of this study was to assess the impact of impact of openness, foreign direct investment, and gross capital formation on economic growth in Kenya with the years under consideration being 1960 to 2010. There are many components of international trade that effect economic growth, but this paper examined the effect impact of openness, foreign direct investment, gross capital formation on Kenyan economic growth. World Bank data for these variables were analyzed in order to achieve the desired objectives. A multiple linear regression model, Barro growth model, was used to estimate the existing the relationship between variables then ordinary least square method was applied. From the findings, trade openness affect the Kenyan economic growth positively (? 1 = 3.062, p<0.05), while foreign direct investment and gross capital formation had no significant effect on GDP growth rate. Thus, trade openness is major determinant of economic growth particularly in developing countries. This study recommended the policy makers and the government to emphasize trade openness being the robust determinants of economic growth.
