The end-Permian extinction event (EPEE) considered to have been caused by the eruption of Siberian Large Igneous Province (SLIP), age which is critical for extinction-SLIP model evaluation. Tunguska Basin flora during this time, in accordance with EPEE model, supposed killed massive injection into atmosphere poisonous substances such as methane, sulfates, mercury and combastion coals. In additi...

In gold-endowed greenstone belts, ore bodies generally correspond to orogenic gold systems (OGS) formed during the main deformation stage that led craton stabilization (syntectonic period). Most OGS deposits postdate and locally overprint magmatic-hydrothermal systems, such as Au-Cu porphyry mostly magmatic (synvolcanic period) polymetallic intrusion-related (IRGS) of syntectonic period. Porphy...

Winchcombe is a CM chondrite that fell in England on February 28, 2021. Its rapid retrieval was well characterized. Within two polished sections of Winchcombe, terrestrial phases were observed. Calcite and calcium sulfates found sample recovered from field March 6, 2021, halite observed months after its recovery driveway 2, These characterized by scanning electron microscopy, Raman spectroscopy...

there are now several tests available that can assess fetal status. a series of 164 cases of high risk pregnancies were studied in order to assess predictive value of a nonstress test. the majority (36%) of patients complained about postdate pregnancy. a nonreactive test was identified in 24 of the patients (14.6%). fetal distress, low apgar score in 1 and 10 minutes after birth and mean of apg...

Introduction: The density of impact craters is widely used in planetary science to study relative and absolute surface ages and the nature of resurfacing on planets. On Venus, the applicability of such methods is very limited due to the small total number of impact craters (about a thousand) [1-3], which is caused both by shielding with a thick atmosphere and active volcanic/tectonic resurfacin...

Introduction. Venus' ribbon tessera terrain [1,2] (rtt) records ancient environmental conditions significantly different than contemporary Venus [3,4], and geologic relations are consistent with rtt representing the oldest locally exposed unit across Venus [5], although individual tracts of rrt may have formed at differnet times [6]. We have constructed a global geologic map of rtt exposures an...

Objectives: to compare the mechanical, pharmacological or combination of both in induction labour. Methods: This comparative observational study was conducted Department Obs and Gynae, Lady Reading Hospital, from January 2019 December 2019. In this all women presenting labor room with singleton pregnancy gestational age > 37 weeks admitted for were included. All those multiple pregnancies, p...

Background: Normal pregnancy is usually associated with weight gain. Abnormal gain in could result adverse neonatal and maternal outcome. Studies related to this Nigeria are limited.Objective: The aim was evaluate the pattern of feto-maternal outcome among women different body mass indices attending antenatal clinic Federal capital territory (FCT).Study design: This a longitudinal, multicentre ...
