N/A
Abstract: Developmental milestones are anxiously awaited by every parent, particularly in the first year of their child's life. One such milestone is the eruption of their child's first tooth. Natal and neonatal teeth are most commonly a part of deciduous dentition and erupt in the same position as that of deciduous teeth in the arch .natal teeth are those teeth that are present at the time of birth and neonatal teeth are those that erupt within 30 days of life. Clinically, natal teeth are small or normal size, conical or of normal shape. They may reveal an immature appearance with enamel hypoplasia and small root formation. The management of natal and neonatal teeth is largely aimed at their preservation for aesthetics and maintenance of space for eruption of successor tooth. Paediatric dentists should make every effort to educate the parents and the paediatrician on the preferred treatment for the natal teeth. Extraction should be done only by the paediatric dentist to avoid any undue trauma to the underlying tissue. Periodic follow-up by a paediatric dentist to ensure preventive oral health is very essential. Hence, to avoid any further complication, early diagnosis and adequate treatment should be a prime concern in the management of natal and neonatal teeth.

N/A
Abstract: Fault plays an important role in petroleum exploration, especially the fault sealing ability which is the key during the formation of the reservoir. The research analysis the controlling factors on fault sealing ability based on the throw, fault filling and fault section pressure. Throw controls the fault types by influencing the contact status of the sand stratum in both sides of the fault; Fault filling decides the sealing ability on vertical and lateral directions and it is also the key of the membrane sealing in lateral fault seal. The pressure on the fault section controls the vertical sealing ability directly, which means the higher the pressure is, the stronger the sealing ability is.

Abstract: The early neonatal outcome of vaginal breech delivery is an important to determine which way the breech presentation should be dealt with. This will help counseling the pregnant women with breech about the possible early adverse outcome that associated with vaginal breech delivery. This study was done to determine the Early Neonatal Outcome. of breech presentation delivered vaginally at El Sheikh Fadul maternity. This was a descriptive cross sectional hospital based study of vaginal breech deliveries, done from February to August 2015, using a time frame of vaginal breech births of babies alive. Data collection was by a well-designed questionnaire. There were 2812 deliveries during the study period with only 90 patients with vaginal breech deliveries representing 3.2%. Eighty-three women with breech presentation (92.2%) had attended antenatal clinic. Only 58% (52 women) of women had emergency intrapartum ultrasound scans. Thirty-seven babies (41.1%) had respiratory distress, neonatal encephalopathy was present in 19 babies (21.3%), three babies (3.3%) had significant physical injuries. Two babies had lacerations on anus secondary to vaginal examinations and one baby had a fractured clavicle. Neonates discharged from nursery were 91, and there were 8 perinatal deaths. The median birth weight of the newborns was 2370 g with a range of 800 g to 3920 g. There were 8 newborns with a birth weight less than 1000 g. The calculated incidence of perinatal death of the study period was 0.3%. A small percentage (2%) of poor neonatal outcomes occurred subsequent to vaginal breech delivery, with small risk of perinatal morbidity and mortality. low 5-min, Apgar scores, and admission to the neonatal care unit found to be higher in patients who have no antenatal care. However, the majority of undiagnosed breech was delivered vaginally without significant morbidity or mortality.

N/A
Abstract: Plate boundary is often sedimentary basin boundary. Different plate boundary takes different control actions on sedimentary basin. Therefore, the study on the identification plate boundary sedimentary basin is very important. Plate tectonics are three different mechanical properties of its boundary with the adjacent plate with zoning, so ancient and recovery partition plate is identified with the identification of ancient plate boundaries closely linked. However, it is precisely on this fundamental issue where there is a need to look at. Because the so-called boundary is not really determined by plate boundary that divided up the bulk of the plate but not truly Asian plate, the plate and the secondary block, rock. Therefore, in the study of ancient plate, the first problem is to identify the real plate boundary to suture, subduction zones, and expanding boundaries and transform boundary. When plate tectonics in the boundary school division of the plate is determined by a series of geographical, geological, seismic, geophysical and other signs; and for ancient plate boundary is determined, geomorphology, geophysics, seismology methods and logo on the petrology, structural geology, geography and ancient methods of ancient plate replaced by a sign which petrology has special significance.
