Abstract: Pre- eclampsia is one of the commonest medical complications seen during pregnancy. It contributes significantly to maternal and perinatal morbidity and mortality. Dr.J.A.Pritchard in 1955, introduced magnesium sulphate for control of convulsions in eclampsia and is used worldwide. Considering the low body mass index of indian women, a low dose magnesium sulphate regime has been introduced by some authors. Present study was carried out at tertiary care centre in rural area. Fifty cases of eclampsia were randomly selected to find out the efficacy of low dose magnesium sulphate regime to control eclamptic convulsions. Maternal and perinatal outcome and magnesium toxicity were analyzed. It was observed that 86% cases responded to initial intravenous dose of 4 grams of 20% magnesium sulphate . Eight percent cases, who got recurrence of convulsion, were controlled by additional 2 grams of 20% magnesium sulphate. Six percent cases required shifting to standard Pritchard regime, as they did not respond to low dose magnesium sulphate regime. The average total dose of magnesium sulphate required for control of convulsions was 20 grams ie. 54.4% less than that of standard Pritchard regime. The maternal and perinatal morbidity and mortality in the present study werecomparable to those of standard Pritchard regime. The study did not find a single case of magnesium related toxicity with low dose magnesium sulphate regime. Low dose magnesium sulphate regime was found to be safe and effective in eclampsia.

Abstract: Pre-eclampsia and eclampsia are major health problems in developing countries. MgSO4 is the standard drug in the control of convulsions in eclampsia. Our study carried out at PDVVPF’s hospital is based on the low dose regimen than Pritchard, which is suitable for Indian women who are of smaller built thanwomen in western world. This prospective study included 50 eclampsia patients receiving low dose MgSO4 therapy. The loading dose of MgSO4 was 9gm. Following this 2.5 gm was given intramuscularly every 6 hourly for 24 hours after administration of the loading dose. Patients were monitored hourly by observing their respiratory rate, knee jerk and urine output. Out of 50, two patients required Pritchard regimen, rest completely recovered from eclampsia. The maternal and perinatal morbidity and mortality were comparable to those of the standard Pritchard regime. The study did not find a single case of magnesium related toxicity with low dose MgSO4 regime. Low dose magnesium sulphate regime was found to be safe and effective in eclampsia

Abstract: Background: Eclampsia is a hypertensive disorder related to pregnancy, in which there is occurrence of one or more generalized convulsions and or coma, in the absence of other neurologic conditions. It is a common obstetric emergency. Eclampsia is associated with elevated maternal and fetal morbidity and mortality. Objectives: To compare the efficacy of low dose magnesium sulphate (Dhaka) regime with Pritchard regime in Eclampsia. Material and Methods: A prospective randomized study of fifty eclampsia cases, treated with magnesium sulphate (25 each from low dose magnesium sulphate (Dhaka) regime and Pritchard regime) was carried out for one year i.e. January 2010 to December 2010 at Pravara Rural Hospital, Loni. Results were analysed using Statistical Package of Social Sciences (SPSS) 13.0. Results: In the present study, convulsions were controlled in 88% of eclampsia cases with low dose magnesium sulphate (Dhaka) regime. Two cases i.e. 8% had single episode of recurrence of convulsion, which was controlled by giving additional 2 grams of 20% magnesium sulphate intravenous single dose. Perinatal mortality in low dose magnesium sulphate (Dhaka) regime was lesser (24%) than Pritchard regime (32%). Conclusion: Low dose magnesium sulphate (Dhaka) regime was equally effective as Pritchard regime in control of eclamptic convulsions. There was no magnesium related toxicity with low dose magnesium sulphate (Dhaka) regime. Maternal and perinatal outcome was better in low dose magnesium sulphate (Dhaka) regime as compared to Pritchard regime. Key words: Low dose magnesium sulphate (Dhaka) regime, Pritchard regime, Eclampsia, Maternal and foetal outcome
Abrupt Climate Regime Shifts, Their Potential Forcing and Fisheries Impacts  [PDF]
Jianjun Xu, Alfred M. Powell
Atmospheric and Climate Sciences (ACS) , 2011, DOI: 10.4236/acs.2011.12004
Abstract: The purpose of this paper is to investigate whether a logical chain of events can be established to explain the abrupt climatic regime shift changes in the Pacific that link the atmosphere to the ocean to fisheries impacts. The investigation endeavors to identify synchronous abrupt changes in a series of data sets to establish the feasibility of abrupt of climate change often referred to as regime shifts. The study begins by using biological (fish catch/stock) markers to mathematically identify the dates of abrupt change. The dates are confirmed by a literature search of parameters that also show abrupt changes on the same dates. Using the biological date markers of abrupt change, analyses are performed to demonstrate that the interactions between the atmosphere, ocean, ecosystems and fisheries are a plausible approach to explaining abrupt climate change and its impacts.
Computer Simulation of Transition Regimes of Solitons in Four-Photon Resonant Parametric Processes in Case of Two-Photon Resonance  [PDF]

American Journal of Computational Mathematics (AJCM) , 2016, DOI: 10.4236/ajcm.2016.63028
Abstract: The transition regimes of solitons in four-photon resonant processes in the case of two-photon absorption of the fundamental radiation are numerically investigated. The standard system of equations for the amplitudes of probability of finding the system in state with certain energy is used to derive the expression for the induced polarization in the nonlinear medium. As for the equations for the amplitudes of the optical pulses, the general case is considered in which both the amplitudes and phases are space-time dependent. We focus on the finite difference methods and the case of simultaneously propagating solitons at all frequencies of the interacting waves (simultons). The obtained results indicate that upon certain threshold conditions all interacting pulses become the solitons of Lorentzian shape. The numerical analysis has also shown that the soliton amplitudes significantly depend on the ratio between the nonlinear polarizability at the fundamental frequency ω0 and that of combination of ω0 and the trigger-field frequency ω1(2ω0 + ω1). In the second part of the paper, we apply the method of phase planes to show that at typical values of parameters, the solitons are stable.
Structural Styles and Petroleum Potential of Miano Block, Central Indus Basin, Pakistan  [PDF]

Abstract: The main purpose of this research article is to evaluate the structural styles and hydrocarbon potential of Miano Block using seismic and well log data. The Miano Block discovered in 1993 is located in the Central Indus Basin which is a part of an extensional regime exhibiting normal faulting, formed as a result of split of the Indian Plate firstly from Africa and then from Madagascar and Seychelles. Tectonically, the Miano Block lies on the Panno-Aqil graben between two extensive regional highs i.e. Jacobabad-Khairpur High and Mari Kandhkot High. Four migrated seismic lines were used for structural enhancement; P2092-111, P2092-113 and P2092-115 (dip lines) and P2092-110 (strike line). Time and depth contours were generated for four horizons, HabibRahi Formation, Sui Main Limestone, Ranikot Formation and Lower Goru Formation which showed the presence of horst and graben structures in the subsurface. The interpretation of horst and graben structures is based on a parallel set of NS-oriented high-angle planar normal faults with dips either towards SE or SW with majority of the faults dipping towards the SW. The faults are observed to exhibit slight disruption of strata with limited displacement to the order of about 50 m in Lower Goru Formation. Thus, horst and graben structures with NS trend in the study area are interpreted. The NS trend of these structures along with similar structural dip is inconsistent to the NW-SE orientation of regional structures i.e. Panno- Aqil graben and the Jacobabad-Kharipur and Mari-Kandhkot Highs indicating about the presence of a second minor set of faults and complexity of deformation. In this setting, Maino-02 well was drilled with the primary target as B-Sands of Lower Goru Formation belonging to Lower Cretaceous age while secondary target was A-Sands of Lower Goru belonging to the same age. The result of the petrophysical analysis supports two potential zones (zone 1 and zone 2) within the Lower Goru Formation. Potential reservoir zones were marked with average hydrocarbon saturation of zone 1 calculated as 63.5% and that of zone 2 as 68.9%.
O fantasma de Evans-Pritchard: diálogos da antropologia com a sua história
Rosa,Frederico Delgado;
Etnográfica , 2011,
Abstract: through the reading of sharon hutchinson?s monograph on the nuer, this article explores the misunderstandings between contemporary anthropology and the modern classics. it tries to identify invisible genealogies that go back to the british functionalists, particularly to evans-pritchard, and minimizes the explicit oppositions between the present and the past of anthropology. it reveals that some classical notions are detectable in non-explicit ways among those who claim to reject them and, at the same time, that contemporary concerns have their roots in modern ethnographies. the author shows that static approaches - as the one by evans-pritchard on the nuer - had a historical meaning and recalls that british social anthropology had its own theoretical and methodological answers to the transformations of african contexts under colonial rule.
Conflitos recentes, estruturas persistentes: notícias do Sud?o
Perrone-Moisés, Beatriz;
Revista de Antropologia , 2001, DOI: 10.1590/S0034-77012001000200004
Abstract: in march 2000, a dinka-nuer peace treaty was signed in southern sudan. the civil war that had been going on for decades, as well as the resolutions adopted, described in the press and present in the documents, acquire full meaning when one considers evans-pritchard's deep analysis of nuer politics. the nuer structures revealed in his works, having persisted for decades, pass the "test of history", and lead to a reconsideration of his contributions to the understanding of the inter-play between structure and history
Dark Energy as a Vacuum Component of the Universe  [PDF]
Vladimir Burdyuzha
Journal of Modern Physics (JMP) , 2013, DOI: 10.4236/jmp.2013.49160

The vacuum component of the Universe is investigated in both the quantum and the classical regimes of its evolution. The associated vacuum energy density was reduced by more than 78 orders of magnitude in 10-6 sec in the quantum regime and by nearly 45 orders of magnitude in 4 × 1017 sec in the classical regime. The vacuum energy was spent for the organization of new microstates during the expansion of the Universe. In the quantum regime, phase transitions were more effective in reducing the vacuum energy than in producing new microstates. Both of these phenomena have been recorded in the history of the Universe. Herein, the need for the evolution of the Universe’s vacuum component is discussed. Indeed, through this evolution, all 123 crisis orders of dark energy are reduced by conventional physical processes. A table of the vacuum energy’s evolution as the function of red shift and a short discussion about vacuum stability are presented.

Is the Great Moderation Ending?——UK and US Evidence  [PDF]

Abstract: The Great Moderation, the significant decline in the variability of economic activity, provides a most remarkable feature of the macroeconomic landscape in the last twenty years. A number of papers document the beginning of the Great Moderation in the US and the UK. In this paper, we use the Markov regime-switching models to document the end of the Great Moderation. The Great Moderation in the US and the UK begin at different point in time. The explanations for the Great Moderation fall into generally three different categories—good monetary policy, improved inventory management, or good luck. The end of the Great Moderation, however, occurs at approximately the same time in both the US and the UK. It seems unlikely that good monetary policy would turn into bad policy or that better inventory management would turn into worse management. Rather, the likely explanation comes from bad luck. Two likely culprits exist—energy-price and housing-price shocks.
