Abstract:

Introduction: Knowledge of fetal weight in utero is vital for the obstetrician in deciding whether or not to deliver the fetus as well as in fixing the mode of delivery. Both low birth weight and excessive fetal weight at delivery are associated with increased risk of newborn complications during labor and the puerperium. Various clinical formulae like Johnson's formula & Dare's formula and USG are in use for fetal weight estimation.Objectives: The aim of this study was to assess the fetal weight in term pregnancies by various methods- Dare’s formula, Johnson's formula and Hadlock's formul

Abstract Accurate fetal weight estimation is important for the management of birth. According to the existing literature, none of the clinical techniques is superior to any other. This study aimed to compare error analysis for the determination of the accuracy of Johnson’s formula, Dare’s formula and mother's opinion for the estimation of birth weight. A cross-sectional study involving 147 full-term, cephalic, singleton pregnancies, was performed. The mother’s opinion was recorded and Johnson’s and Dare’s formulas were used to calculate the fetal weight. Accuracy was determined by percentage e

Measurement of uterine fundal height (TFU) to determine the estimated fetal weight (TBJ) is an important component of antenatal care in labor management. Babies born with low body weight or born with very large body weight are associated with increased complications during labor and the puerperium. This study aims to compare the accuracy of the Risanto and Johnson Toshack formulas in determining the estimated fetal weight.

Abstract:

Introduction: The estimation of fetal weight during pregnancy has a significant impact on the survival of newborns and some immediate and late sequelae of the life of newborns. Estimation of fetal weight also plays a paramount role in determining time, mode, and place of delivery. There are many methods to estimate fetal weight like the palpation method, fundal height measurement, and radio frequency volume reduction. Johnson's method is one of the clinical methods that require no expense and is easier to estimate the precise birth weight and fetal weight. This study aimed to analyze the accur

Abstract:

Background: Estimation of fetal weight is essential for prenatal care and delivery management. Clinical methods, such as symphysiofundal height (SFH) assessment, and ultrasound-based techniques are commonly used for this purpose. Maternal body mass index (BMI) can influence fetal weight estimation accuracy, particularly in obese patient. In periphery where ultrasound facilities are not available clinical estimation of fetal weight plays very important role in antenatal care. This study was aimed to examine the impact of maternal BMI on the accuracy of clinical fetal weight estimation. Methods:

Abstract:

Niki Johnson shows that despite Uruguay being an institutionalized democracy, women have struggled to make numerical progress in politics. Formal and informal institutions that are inherently ridden with political biases limit women’s representation. Small district and party magnitudes along with male-biased candidate selection rules hindered women’s entry into office until the adoption of a gender quota, which was applied minimally by the main parties. Even with a quota, they still do not prioritize gender as a criterion for political office. Johnson points out that substantive representation

"that both Syrians and Americans are more likely to either accept or mitigate the force of the compliment than to reject it. Both groups employed similar response types (e.g. agreeing utterances, compliment returns, and deﬂecting or qualifying comments); however, they also differed in their responses. US recipients were much more likely than the Syrians to use appreciation tokens and a preferred Syrian response, acceptance + formula, does not appear in the US data at all. Recently, in a conversation with an American who had taught EFL in Damascus for two years, one of the researchers mentioned that she was investigating the strategies Syrians use in responding to compliments. The teacher looked surprised and asked, ‘What’s there to study? Syrians just say Shukran (“thank you”). When I’m complimented in Arabic, that’s what I say – Shukran.’ This teacher was apply-ing a rule from his L1 speech community to an L2 speech community. The rule he was transferring is one that American parents teach their children and one that is taught in etiquette books: ‘When you are complimented, the only response nec-essary is “Thank you” ’ (Johnson 1979: 43). Compliment responses in Syrian Arabic, as shall become clear later, are much more complex than saying Shukran when praised. In this paper, we report on a study of Syrian Arabic speakers’ and American English speakers’ verbal responses to compliments. The purpose of the study is to better understand the strategies used by Syrians and Americans in responding to compliments, to discover similarities and differences between the two groups, and to relate the ﬁndings to second language acquisition and second language teaching."

The Hertz contact theory allows the onset of yielding to be predicted for those contacts in which the effect of adhesion can be neglected. However in microscale contacts, such as those which occur in MEMS, yielding will occur for lower loads than predicted by the Hertz theory. For such cases, the JKR, DMT, and Greenwood-Johnson theories extend the Hertz theory to include the effect of adhesion. The present study provides yield conditions for the JKR, DMT, and Greenwood-Johnson theories of adhesion. Attention is first focused on the initiation of yield along the axis of symmetry of the contact.
