ABSTRACT
Jeans, C.V., Hu, X-F and Mortimore, R.N. 2012. Calcite cements and the stratigraphical significance of the marine δ 13 C carbonate reference curve for the Upper Cretaceous Chalk of England. Acta Geologica Polonica, 62 (2), 173-196. Warszawa.
The hypothesis of Jarvis et al. (2006) that a δ 13 C (calcite) reference curve based upon bulk samples from the Upper Cretaceous Chalk of England can be used as a primary criterion for trans-continental correlation is reviewed in the light of new stable isotope data from the Upper Albian and Cenomanian chalks of eastern England and from the Cenomanian to Campanian chalks of southern England. Evidence demonstrates that in the coloured chalks of eastern England the cements invariably have positive δ 13 C values (up to 3.5‰) except where they have been affected by hardground development when the cements have negative δ 13 C values down to -6.5‰. In contrast, the White Chalk of southern England may have cements with δ 13 C values as negative as -8‰. Modelling indicates that the coloured chalks may preserve a truer record of the primary palaeo-oceanographic δ 13 C signal than the white and grey chalks of southern England. It is suggested that (1) many of the 72 isotope events described from the δ 13 C (calcite) reference curve and proposed for correlation may reflect the effects of variations in the type and extent of calcite cementation; and (2) until much more is known about the patterns of calcite cementation in the Upper Cretaceous Chalk the use of minor isotope events for trans-continental stratigraphic correlation can only be applied with the utmost caution.

ABSTRACT
Aubrecht, R., Meres, Š., Gradziński, M. and Sykora, M. 2012. High (ultrahigh) pressure metamorphic terrane rocks as the source of the detrital garnets from the Middle Jurassic sands and sandstones of the Cracow Region (Cracow- Wieluń Upland, Poland). Acta Geologica Polonica, 62 (2), 231-245. Warszawa. The Middle Jurassic (Upper Bathonian/Lower Callovian) sands and sandstones of the Cracow-Wieluń Upland contain detrital garnets with high contents of the pyrope molecule (30-73 mol %). The predominance of detrital pyrope garnets, and inclusions represented mainly by omphacite and kyanite, show that the garnets were derived from high (ultrahigh) pressure (H/UHP) metamorphic terrane rocks (garnet peridotites, eclogites and granulites). Their source is unknown. The Moldanubian Zone of the Bohemian Massif is closely comparable. However, the terranes between this zone and the Cracow- Wieluń Upland are dominated by almandine garnets. The relatively low proportion of almandine garnets in the examined samples indicates that transport of the detrital material could not have been from a far distant source as the garnet assemblage would otherwise be strongly dominated by almandine. A less distant possible source could have been the Gory Sowie Mts., which incorporate UHP/HP metamorphic rocks, but the exposed areal extent of these rocks is too small. It is possible that larger portions of these metamorphic rocks are buried beneath the Cenozoic cover and might have earlier represented a larger source area. Reworking of the entire heavy mineral spectra from older clastics is improbable because of the low maturity of the heavy mineral assemblages (higher proportion of less stable minerals). The source area therefore remains unknown. Most probably it was formed by primary crystalline complexes of lower crust to mantle origin, outcrops of which were not far distant from the area of deposition. Similar detrital garnet compositions were also recorded in the Outer Western Carpathians (Flysch Zone, Pieniny Klippen Belt), i.e. the crustal segments which formed the Silesian and Magura cordilleras; the Czorsztyn Swell was also formed by similar rocks.
Organic-walled dinoflagellate cysts from the Bathonian ore-bearing clays at Gnaszyn, Kraków-Silesia Homocline, Poland – a palaeoenvironmental approach

ABSTRACT
Gedl, P. 2012. Organic-walled dinoflagellate cysts from the Bathonian ore-bearing clays at Gnaszyn, Kraków- Silesia Homocline, Poland - a palaeoenvironmental approach. Acta Geologica Polonica, 62 (3), 439-461. Warszawa.
A succession of Middle-Upper Bathonian (Subcontractus-Retrocostatum zones) ore-bearing clays exposed at Gnaszyn has been investigated for the presence of dinoflagellate cysts. The assemblages are dominated by Ctenidodinium. However, analysis of diversity shows some subtle differences throughout the succession, possibly related to the palaeoenvironmental conditions in the photic zone. Impoverished assemblages, dominated by Ctenidodinium, occur mainly in monotonous muddy intervals. More diverse assemblages, albeit also dominated by Ctenidodinium, occur in intervals which contain siderite concretion levels. The taxonomic composition of the former assemblage seems to reflect slightly restricted conditions in the photic zone, possibly related to a minor reduction in salinity and/or increase in nutrient availability. More diverse dinoflagellate cyst assemblages reflect periods of less intense terrigenous influx and relatively higher, possibly normal, salinity. These changes were possibly caused by variable intensity of freshwater influx into the basin, controlled by sea-level fluctuations. Sea-level changes may be related to migrations of Tethyan water masses, which were probably partly responsible for the composition of the dinoflagellate cyst assemblages.

Authors: Burbelko A.A. , Gurgul D. , Kapturkiewicz W. , Górny M. 
Published: February 2013

Abstract
The mathematical model of the globular eutectic solidification in 2D was designed. Proposed model is based on the Cellular Automaton Finite Differences (CA-FD) calculation method. Model has been used for studies of the primary austenite and of globular eutectic grains growth during the ductile iron solidification in the thin wall casting. Model takes into account, among other things, non-uniform temperature distribution in the casting wall cross-section, kinetics of the austenite and graphite grains nucleation, and non-equilibrium nature of the interphase boundary migration. Calculation of eutectic saturation influence (Sc = 0.9 - 1.1) on microstructure (austenite and graphite fraction, density of austenite and graphite grains) and temperature curves in 2 mm wall ductile iron casting has been done.

In addition the results of visualisations of the core-box filling with the sand-air stream, from the blowing chamber, obtained by the process filming by means of the quick-action camera are presented in the paper and compared with the results of simulation calculations with the application of the ProCast software.
The Effect of Ductile Cast Iron Matrix on Zinc Coating During Hot Dip Galvanising of Castings
Authors: Kopyciński D. , Szczęsny A. 
Published: February 2013

Abstract
The growth kinetics of the zinc coating formed on the surface of casting made from ductile iron grade EN-GJS-500-3 was investigated. To produce homogenous metal matrix in test samples, the normalising and ferritising annealing was carried out. Studies showed a heterogeneous structure of cast iron with varying content of the phases formed. This was followed by hot dip galvanising treatment at 450°C to capture the growth kinetics of the zinc coating (the time of the treatment ranged from 60 to 600 seconds). Nonlinear estimation of the determined growth kinetics of the alloyed layer of a zinc coating was made and an equation of the zinc coating growth was derived. Based on the results of the investigations it was concluded that thickness of the zinc coating formed on the surface of casting with a 100% pearlitic matrix makes 55% of the thickness of coating formed on the surface in 100% ferritic.

Nine year results of growth and yielding estimation of six scab-resistant apple cultivars grafted on three dwarfing rootstocks in integrated fruit production
Authors: CZYNCZYK ALOJZY 
Published: February 2013

ABSTRACT
During the nine years (2002-2010) 6 apple cultivars, scab-resistant or partially resistant to apple scab: ‘Bohemia’, ‘Topaz’, ‘Rubinola’, ‘Goldstar’, ‘Pinova’ and ‘Redkroft’ grafted on 3 dwarfing rootstock: M.9, P 22 and P 60, were tested at the Experimental Orchard in Dąbrowice with integrated fruit production. The susceptibility to apple canker (Nectria sp.), apple scab and powdery mildew, as well as growth, yielding, fruit quality and damage by pests were observed. After 9 years, the highest number of infected trees, on trunks and branches, were observed on the cultivars: ‘Topaz’, ‘Bohemia’, and ‘Redkroft’. All the cultivars grafted on P 60 rootstocks formed the largest trees, whereas on P 22 the smallest. The highest yields were obtained from all the cultivars grown on P 60 and the smallest on P 22. The cropping efficiency index was the highest for: ‘Bohemia’, ‘Rubinola’, ‘Goldstar’ and ‘Pinova’ on P 22. ‘Topaz’ had the highest cropping efficiency on P 60 and ‘Redkroft’ on M.9 and P 60. In the last three years (2008-2010), the effect of rootstock on fruit quality was minimal and not significant. Apple scab and powdery mildew, and some important pests, were not observed after applying on integrated system of spraying. The apple cultivars: ‘Bohemia’, ‘Rubinola’, ‘Topaz ‘and ‘Redkroft’ are the most promising for processing and amateur orchards with the integrated system of management. The cultivars: ‘Pinova’ and ‘Goldstar’ should not be recommended for growing on light soil in the integrated system of production. The fruits of ‘Goldstar’ are susceptible to bitter pit.
Effects of organic and inorganic nitrogen on growth, yield and quality of Sapota ‘Kalipatti’
Authors: Devashi Varu 
Published: February 2013

ABSTRACT
An experiment was conducted to study the effect of organic and inorganic nitrogen in the form of urea and castor cake on the growth, yielding and fruit quality of sapota trees. Nitrogen in the form of urea significantly influenced the vegetative growth of the trees. The greatest tree height (7.26 m), tree spread (8.11 m in N-S and 8.13 m in E-W directions), fruit weight (63.65 g), the number of fruit per tree (2627.56) and fruit yield per tree (163.30 kg) were obtained with the application of 900 g N/tree in the form of urea. However, that was found on a par with the application of 900 g N/tree in which 50% N was from urea and 50% from castor cake. Total sugars and reducing sugars content in fruit was found the highest in the 900 g N/tree treatment in which 25% N was from urea and 75% N from castor cake.
Invariant Method of Load Independent Pressure Control in Steam Boiler
Authors: Sniders Andris , Komass Toms 
Published: February 2013

Abstract
The paper considers the possibility of steam production and supply process improvement by perfection of the steam boiler control system, applying invariance principle that makes possible preemptive compensation of the influence of steam expenditure as a disturbance on the control process quality and efficiency. For the development of invariant control system, the mathematical modeling and simulation in MATLAB - SIMULINK environment is made. The control unit is low pressure steam boiler with one input impact to control - the heat flow of burning gas mixture fuel, one measured output parameter of the process - the steam pressure, and the main disturbance as a load impact - the steam expenditure. The mathematical and virtual models and block-diagrams for transient process simulation is compiled, allowing to start practical design and investigation of steam boiler invariant control system with high operation stability under essentially fluctuating load. The simulation results prove that the optimal solution for the transient process improvement in steam boiler, taking in account fluctuating load, is invariant PID-DPC two loop control system with disturbance impact on steam pressure preemptive compensation. Under invariant control the steam pressure overshoots decreases substantially in comparison with the traditional PID-feedback control method.

Authors: Tetervenoks Olegs , Galkin Ilya , Armas Jelena 
Published: February 2013

Abstract
Usually wireless devices require autonomous power supply. They are equipped with radio frequency transceiver modules with relatively high energy consumption especially in data transmission mode. This also means that autonomous power supply of wireless device requires relatively large energy storage. Rechargeable battery in this case is a good solution, but the charging process of a battery takes a long time. In this paper the use of supercapacitor as energy storage for autonomous power supply of wireless node is further elaborated on the example of light sensor for illumination measurement test bench.
Clinique de la violence transgénérationnelle... à partir d'un dispositif de thérapie familiale psychanalytique
Authors: Joubert Christiane , Ravit Magali , Gaillard Georges , Grange-Ségéral Évelyne , Vivier-Vacheret Claudine 
Published: February 2013

Résumé Nous avons montré, au sein d’une thérapie familiale psychanalytique, que le trans­générationnel entraîne une grande violence dans les liens familiaux. Il peut se déposer sur, se destiner à un membre de la famille, peut-être le plus fragile, qui fait alors figure d’intrus à éliminer. Cela va se répéter au niveau générationnel, avec par exemple une mort subite du nourrisson et des avortements. Nous nous appuyons sur la théorie de J. Bergeret (à partir des quatre niveaux de réflexion structurant les fantasmes originaires) et sur le concept de « violence fondamentale » que nous lui empruntons.
Le Periphyseon d'Érigène comme une extrapolation de l'Ambiguum 41 de Maxime le Confesseur
Authors: Guiu Adrian , Lemaire Juliette 
Published: February 2013

Résumé Cet article examine la manière dont Jean Scot Érigène s’approprie et emploie de façon constructive l’anthropologie de Maxime le Confesseur. Il s’agit de montrer que la division en cinq parties de l’être, puisée dans l’ Ambiguum 41 de Maxime le Confesseur, constitue le cadre du Periphyseon . Selon l’auteur, la compréhension de l’être humain de Maxime le Confesseur comme « un atelier de création », comme la synthèse de tous les aspects de la création, comme un agent d’unification, fournit la prémisse anthropologique pour la division dialectique du genre de la nature propre à Érigène. C’est dans le cadre de l’ontologie de Maxime centrée sur « l’homme comme un atelier de création » qu’Érigène a recours à la tradition des arts libéraux. Par conséquent, la division du genre de la nature comme un exercice dialectique doit être comprise dans le cadre de l’appropriation par Érigène de la division en cinq parties de l’être de Maxime le Confesseur, ainsi que de son corollaire, l’anthropologie de l’ officina omnium o. Le projet du Periphyseon est guidé par la possibilité qu’à travers l’application des arts, l’homme pourrait devenir l’ officina omnium , en dépit de la chute ; si la connaissance intellectuelle de la création peut être achevée, alors le retour de toute la création à l’unité de l’être humain intelligible et ultimement à celle de Dieu pourrait être garanti.
Le langage de l'union mystique : le désir et le corps dans l'œuvre de Jean Scot Érigène et de Maître Eckhart
Authors: Otten Willemien , Lachance Geneviève 
Published: February 2013

Résumé L’article propose une analyse comparative de la pensée mystique de Jean Scot Érigène (810-877) et de Maître Eckhart (1260-1328). Nuançant les critiques contemporaines relatives au rôle joué par l’expérience dans le mysticisme médiéval, il défend la position selon laquelle il est préférable d’instaurer une comparaison sémantique détaillée de la pensée de ces deux auteurs plutôt que de diviser le mysticisme médiéval en fonction de l’influence mystique augustinienne ou dionysienne décelable chez chacun d’entre eux. L’auteure mène une telle analyse en se reposant sur l’utilisation du concept d’incarnation comme principe sémantique fécond et non comme doctrine théologique. Tandis qu’Érigène utilise ce concept pour engager la conversation avec le divin (utilisation « horizontale »), Eckhart s’en sert pour donner naissance à une vision mystique plus incisive (utilisation « verticale »). Nuançant également l’idée selon laquelle l’apophase est une caractéristique commune de la tradition néoplatonicienne médiévale, l’auteure montre qu’Érigène et Eckhart utilisent l’apophase pour obtenir des effets fort différents. Guidés par leur désir de percer tout mécanisme de la contemplation mystique sans pour autant discréditer l’expérience en tant que telle, Érigène et Eckhart ne conçoivent pas l’apophase en contradiction avec la corporalité, mais l’utilisent pour affirmer l’ordre sous-jacent et le caractère commun de la nature et de la vie.
Peut-on parler d'espèce symbolique ?
Authors: Forest Denis 
Published: February 2013

Résumé Dans L’animal, l’homme, la fonction symbolique (1964), Raymond Ruyer cherchait à caractériser la spécificité de l’homme à l’intérieur du monde biologique et il en distinguait trois traits constitutifs : le rôle modifié du cerveau, la transmission ou « hérédité » culturelle, la dimension symbolique du langage. Sa thèse était qu’il faut chercher dans le maniement des symboles ce qui rend possible les diverses manifestations de la culture, et qu’en vertu de cette origine commune, ces manifestations doivent être considérées comme indissociables. Mais, il y a chez Ruyer, une troisième voie entre émergence et réduction. Il a, en ce qui concerne les symboles, une dette à l’égard de Cassirer et surtout de Susanne K. Langer. Enfin les acquis en éthologie cognitive et les recherches contemporaines sur l’évolution de la faculté du langage permettent d’apprécier avec quelque scepticisme la position de Ruyer.

Published: February 2013

ABSTRACT

Objectives
The purpose of the study is to determine the level of serum uric acid (s. uric acid) above which all complications occur, to analyze the maternal and fetal clinical and laboratory changes associated with elevated s. uric acid, and to determine whether s. uric acid can be used to predict maternal and fetal complications.

Design
A retrospective study of hospital records was done on 80 women of pregnancy induced hypertension including both gestational hypertension and preeclampsia from January 2011 to March 2012 at Civil Hospital, Ahmedabad. The women were divided in two groups: with s. uric acid > 6 mg/dl/ s. uric acid < 6 mg/dl.

Results
S. uric acid > 6 mg/dl was associated with maternal complications while s. uric acid > 5.5 mg/dl was associated with low birth weight babies. The mean creatinine and platelet count in two groups were significantly different at 5% level. Statistically significant elevation of s. uric acid was found in women of eclampsia.

Conclusion
S. uric acid > 6 mg/dl is associated with increased maternal complications specially eclampsia and higher incidence of low birth weight. Thus, women with pregnancy induced hypertension with s. uric acid > 6 mg/dl should be offered termination of pregnancy.

Sexual Dysfunction in Women: An Overview of Risk Factors and Prevalence in Indian Women
Authors: Aggarwal Rohina S , Mishra Vineet V , Panchal Navin A , Patel Nital H , Deshchougule Vrushali V , Jasani Anil F 
Published: February 2013

ABSTRACT

Objective
To detect the prevalence of sexual dysfunction and also to investigate possible risk factors that may cause sexual dysfunction in the Indian women.

Materials and methods
The prospective study consisted of 500 women between ages 18 and 66 years from different sociocultural areas. The women were divided into five groups according to their ages <24 years (n = 129), 24 to 30 years (n = 182), 31 to 37 years (n = 125), 38 to 42 years (n = 22), >42 years (n = 42). Female sexual function was assessed with a detailed 19-item FSFI questionnaire to evaluate five domains of sexual dysfunction, i.e. desire, arousal, lubrication, orgasm and pain. Demographic characteristics and medical risk factors were evaluated and findings were compared between the women with and without sexual dysfunction.

Results
Based on total sexual function score, 278 (55.6%) of total 500 patients had sexual dysfunction. The commonest dysfunction was orgasmic (91.7%) followed by lubrication (89.2%). Out of 278 patients, 53 patients (19%) were in the age of more than 38 years in the FSD group. Female sexual dysfunction was more prevalent in illiterate women, 7.19% patients were illiterate in the FSD group as compared to 3.15% patients in the women with no FSD (p = 0.04). It shows that prevalence of female sexual dysfunction was significantly higher in the older age group and in illiterate patients.

Conclusion
The prevalence of female sexual dysfunction rises with age, lower education level, chronic disease and menopausal status.
