To explore the infectivity of predelivery women with different modes of hepatitis B virus infections to their fetuses, eight indicators (HBsAg, anti-HBs, HBcAg, anti-HBc, HBeAg, anti-HBe, PHSA-R and anti-HBc-IgM) in serum of mother and umbilical cord blood of baby were detected. By matched pairs the result s showed that there were 170 mothers whose serum was positive for more than one indicator. The positive rate was 47.2% altogether. 15 infections modes appeared. There were 18 mothers whose serum was positive for HBsAg. Of their baby, there were 16 whose umbilical card blood was positive for HBsAg. From mother to baby, the infection rate was 88.8%(16/18). There were two babies whose umbilical cord blood was positive for HBsAg, but the serum of their mother was only positive for anti-HBc. There was one case, the umbilical cord blood of baby was positive for HBsAg, but the serum of his mother was all negative for these eight indicators. (author)

God-mother-baby: what children think they know.

Kiessling, Florian; Perner, Josef

2014-01-01

This study tested one hundred and nine 3- to 6-year-old children on a knowledge-ignorance task about knowledge in humans (mother, baby) and God. In their responses, participants not reliably grasping that seeing leads to knowing in humans (pre-representational) were significantly influenced by own knowledge and marginally by question format. Moreover, knowledge was attributed significantly more often to mother than baby and explained by agent-based characteristics. Of participants mastering the task for humans (representational), God was largely conceived as ignorant "man in the sky" by younger and increasingly as "supernatural agent in the sky" by older children. Evidence for egocentrism and for anthropomorphizing God lends support to an anthropomorphism hypothesis. First-time evidence for an agent-based conception of others' knowledge in pre-representational children is presented. © 2013 The Authors.

Breastfeeding is recognized as the single most cost-effective intervention to reduce child morbidity and mortality. However, few studies have explored perceived barriers to breastfeeding and factors associated with breastfeeding intent among mothers of newborn babies in Viet Nam. We conducted a study to assess breastfeeding initiation rates, intent to breastfeed exclusively for 6 months or more and perceived barriers to breastfeed among mothers of newborn babies in Da Nang, Viet Nam. We conducted a cross-sectional questionnaire survey of mothers in the postnatal wards of Da Nang Hospital for Women and Children in central Viet Nam from 10 February 2017 to 24 February 2017, following implementation of the World Health Organization (WHO) Essential Newborn Care (ENC) package. Of 286 mothers surveyed, 259 (90.6%) initiated breastfeeding; 203/258 (78.7%) within 1 hour (h) of birth. Most (207, 72.4%) mothers indicated intent to breastfeed exclusively for 6 months or more, but this was lower among mothers of preterm babies (82.2% versus 20.0%, p  < 0.001) and those without post-secondary school education (74.8% versus 55.6%, p  = 0.02). Amongst mothers struggling to establish breastfeeding, 18/27 (66.7%) had a Cesarean section. Planned non-exclusive breastfeeding was mostly (39, 60.9%) motivated by mothers' concern that their milk supply would be insufficient for their baby's growth requirements. Most mothers had good knowledge about the benefits of breastfeeding and indicated strong decision autonomy. We documented high rates of early breastfeeding establishment and intent to breastfeed exclusively for 6 months or more. This probably reflects high levels of maternal education and successful implementation of the WHO ENC package. Mothers of premature babies may benefit from additional support.

this paper explores changing messages about place of birth offered to women by Mother and Baby magazine, a UK publication aimed at a general readership DESIGN: the research uses an historical perspective to explore changing messages about place of birth in Mother and Baby magazine between 1956-1992. It analyses the content and medium of the magazine through a narrative and semiotic approach. the UK between the mid-1950s and 1990s. The period was a time of significant change in the maternity services, at both a philosophical and organisational level with a move towards hospital rather than home birth and a dominant discourse which privileged medical models of care over social ones. producers and consumers of Mother and Baby magazine FINDINGS: Mother and Baby moved from an assumption of home birth to a focus on hospital birth, reflecting national changes in policy. The magazine moved from a social to a risk focused medical view of birth, with an emphasis on the safety of the baby and the sacrifice of the mother. These changes can be traced through both the organisation and the language of content between 1956 and 1992. However, home birth was always offered to readers as a viable, if increasingly niche, option. This reflected the magazine's need to appeal to its readers as consumers; both in consumption of the magazine and of maternity care. the evidence suggests that Mother and Baby magazine mirrored elements of the prevailing policy discourse around place of birth. However, it always gave space to other narratives. In doing so it reminds us of the complexity about how messages about labour and birth are told and received. It gives insight into ways in which the media lead and reflect change and the impact this might have on decision making by women. Copyright © 2017 Elsevier Ltd. All rights reserved.

Full Text Available Loss-to-follow-up (LTFU throughout the Prevention of Mother-To-Child Transmission (PMTCT cascade remains one of the major threats to the success of PMTCT programs. In this study, we aimed to determine the mother-to-child transmission rate in a programmatic setting and to determine factors associated with LTFU among enrolled mothers and unfavorable outcomes among HIV-exposed babies which includes being HIV positive, death and LTFU.A retrospective cohort study reviewing routinely collected data in an Integrated HIV care program, Mandalay, Myanmar in June 2016.LTFU means mother/infant missing appointed visit for more than three months.Of 678 pregnant women enrolled in PMTCT program between March 2011 and June 2014, one stillbirth and 607 live births were recorded in this cohort. Of 457 HIV-exposed babies with HIV-test recorded at the end of the intervention, nine (2% were HIV-positive. Pregnant women's and exposed-babies' LTFU rate was 7 per 1000 person-years, and 10 per 1000 person-years respectively. PMTCT option B protocol was found to be significantly associate with maternal LTFU [adjusted Hazard Ratio (aHR 95% CI: 3.52 (1.38-8.96] when compare to mothers receiving option B+/lifelong antiretroviral therapy (ART.

However, a high proportion of HIV-infected mothers and exposed babies LTFU was recorded. Lifelong ART provision to HIV-positive pregnant women was shown to reduce exposed babies' LTFU, death and transmission rate (unfavorable outcomes in this setting. Lessons learned from this program could be used to

Full Text Available In adults, hypothyroidism caused by thyroid stimulation blocking antibody (TSB Ab is rare, and confirmed cases are even fewer, as TSB Ab levels are rarely assayed. However, this may create problems in babies, as the transplacental passage of maternal TSB Ab can cause a rare type of hypothyroidism in the infant. Prompt levothyroxine replacement for the baby starting immediately after birth is important. We describe a congenital hypothyroid baby born to a hypothyroid mother who was not aware of the cause of her hypothyroid condition, which turned out to be associated with the expression of TSB Ab. This cause was confirmed in both the infant and mother using a series of thyroid function tests and measurements of autoantibody levels, including TSB Ab. During periodic follow-up, the TSB Ab and thyroid stimulating hormone receptor antibody titers became negative in the baby at 8 months of age, but remained positive in the mother. Evaluation of hypothyroidism and its cause in mothers during pregnancy is important for both maternal and child health.

to describe and compare sexual and reproductive history as well as reactions to the pregnancy and attendance in antenatal care, family classes and childbirth of fathers of babies born to teenage mothers and fathers of babies born to average aged mothers. a descriptive comparative study using a structured questionnaire for data collection. eleven postnatal wards at the five obstetric and gynaecological departments in the Stockholm area. 132 fathers of babies born to primiparous teenage mothers (Group A) and the same number of fathers of babies born to primiparous women aged between 25-29 years (Group B) who were present in the postnatal wards. 43 of Group A compared to 17% of the Group B fathers had their first intercourse before 15 years of age. This early sexual debut was related to other health hazard, such as use of illicit drugs and cigarette smoking. The majority of the pregnancies in Group A were unplanned but most fathers reacted positively to the pregnancy and participated in the antenatal care. In contrast, only half of these fathers attended family classes. fathers of babies born to teenage mothers differed from fathers of babies to older mothers regarding reproductive background as well as involvement during pregnancy. The findings of this study challenge midwives to organise clinical practice in order to meet the specific needs of this group.

The aim of this study is to evaluate the emotional stress and its effects on parental self-efficacy and mother-infant attachment in mothers whose babies were diagnosed with retinopathy of prematurity (ROP). Study sample was consisted of voluntarily participating 82 mothers whose babies were first diagnosed with ROP, 83 mothers of preterm babies without ROP, and 85 mothers of term babies admitting for their routine visits. Sociodemographic data form maternal attachment scale, state-trait anxiety inventory, Edinburgh postnatal depression scale, and parental self-efficacy scale were applied to study participants, and the overall results of three groups were statistically compared. The sociodemographic features of three study groups were similar. Statistical significant differences were found in depression and state anxiety levels among study groups, while maternal attachment scale and trait anxiety level scores and parental self-efficacy scale total score were similar in study groups. Maternal depression and state-anxiety levels were tend to be higher in mother of children diagnosed with ROP and prematurity; however, there were no statistically significant differences between levels of mothers' of premature children with or without ROP. This is the first study in literature assessing the additional effect of ROP on the anxiety and depression levels of recent mothers, as well as mother-infant attachment and parental self-efficacy. Supporting of mothers having an infant with diagnosed ROP is crucial because of feeling themselves inefficient and responsible for all interventions applied to their babies.

Full Text Available Kangaroo Mother Care (KMC is a practical technique for nursing of low birth weight babies by direct skin to contact with the mother. This study was undertaken to observe and record the effect of KMC with focus on increase in weight of at term low birth weight (LBW babies weighing less than 2000 grams. The study was conducted over thirty six month’s period from July 2011 to June 2014. The method of care consisted of skin to skin contact between the mother and the infant along with exclusive breast milk. Upon implementation of KMC babies under observation showed satisfactory gain in weight of average 25grams per day and an average hospital stay of 10 days. KMC aims towards achieving good weight gain in LBW babies. It is a simple hassle free technique which can be implemented at all levels of health care.

Full Text Available BACKGROUND: Zambia adopted Option A for prevention of mother-to-child transmission of HIV (PMTCT in 2010 and announced a move to Option B+ in 2013. We evaluated the uptake, outcomes, and costs of antenatal, well-baby, and PMTCT services under routine care conditions in Zambia after the adoption of Option A. METHODS: We enrolled 99 HIV-infected/HIV-exposed (index mother/baby pairs with a first antenatal visit in April-September 2011 at four study sites and 99 HIV-uninfected/HIV-unexposed (comparison mother/baby pairs matched on site, gestational age, and calendar month at first visit. Data on patient outcomes and resources utilized from the first antenatal visit through six months postpartum were extracted from site registers. Costs in 2011 USD were estimated from the provider's perspective. RESULTS: Index mothers presented for antenatal care at a mean 23.6 weeks gestation; 55% were considered to have initiated triple-drug antiretroviral therapy (ART based on information recorded in site registers. Six months postpartum, 62% of index and 30% of comparison mother/baby pairs were retained in care; 67% of index babies retained had an unknown HIV status. Comparison and index mother/baby pairs utilized fewer resources than under fully guideline-concordant care; index babies utilized more well-baby resources than comparison babies. The average cost per comparison pair retained in care six months postpartum was $52 for antenatal and well-baby services. The average cost per index pair retained was $88 for antenatal, well-baby, and PMTCT services and increased to $185 when costs of triple-drug ART services were included. CONCLUSIONS: HIV-infected mothers present to care late in pregnancy and many are lost to follow up by six months postpartum. HIV-exposed babies are more likely to remain in care and receive non-HIV, well-baby care than HIV-unexposed babies. Improving retention in care, guideline concordance, and moving to Option B+ will result in

Full Text Available Zika virus (ZIKV is an emerging mosquito-borne pathogen. ZIKV infection is linked to the development of severe fetal abnormalities that include spontaneous abortion, stillbirth, hydranencephaly, and microcephaly. ZIKV outbreaks have been recorded in the United States. We recently demonstrated the first congenital ZIKV infection in the United States. In this study, we investigated archived blood samples from six mothers who gave birth to babies with microcephaly and 12 mothers who gave birth to healthy babies in Hawaii between 2009 and 2012. We tested maternal blood for the presence of ZIKV IgM and IgG antibodies using commercially available human ZIKV IgM and IgG ELISA kits. Blood from one mother who delivered babies with microcephaly tested positive for ZIKV IgM antibody (16.6% and blood from three mothers tested positive for ZIKV IgG antibody (50%. ZIKV showed a trend toward significance with microcephaly. ZIKV IgG antibody positive mothers were more likely to deliver babies with microcephaly than mothers who were negative for ZIKV IgG antibodies (Odds ratio [OR] = 11.0, 95% confidence interval [CI] = 0.8-147.9, p = 0.083. Similarly, ZIKV IgM antibody positive mothers were also more likely to deliver babies with microcephaly than mothers who were negative for ZIKV IgM antibody (OR = 6.8, 95% CI = 0.2-195.1. These data provide further evidence of a link between ZIKV infection and microcephaly and suggests presence of ZIKV positive cases and associated microcephaly in the United States as early as 2009.

Full Text Available Aim: To evaluate traditional baby care practices employed by mothers in the Turkish province of Trabzon. Materials and methods: This descriptive study was planned around babies born in the provincial center of Trabzon between 1 June and 31 December, 2005, and aged 6-12 months at the time of the research. Data were collected in July-September 2006. In order to determine sampling size the prevalence of mothers using traditional practices was calculated at 50%, with a deviation of 0.05, giving a sample size of 384 mothers, the final number being put at 400. The study was performed at six clinics selected on the basis of settlement location and socioeconomic level out of 11 health clinics in the city center of the province of Trabzon. Data in the study are presented as numbers, and percentage distributions as mean±standard deviation. Results: It was determined that 69.8% of mothers breastfed their babies immediately and that 91.3% gave them colostrum. It was also determined that 3.7% of mothers resorted to various practices in order to ensure a male or female baby, 44.5% in order to facilitate labor, 25% in order to avoid puerperal fever, 63.5% in order eliminate postnatal pain, 88% to prevent their babies smelling, 86.2% for the shedding of the umbilical cord, 54.2% to protect their babies against jaundice, 73.7% to protect their babies from the evil eye, 26.2% so their babies would be good-looking and 40.7% to safely complete the first 40 days after childbirth. The main practices having a harmful effect on health in the study were swaddling, salting the baby, waiting for the call to prayer before breastfeeding the baby after birth and not giving colostrum. Conclusions: Traditions were observed to have an impact and to be persisting in child care in Trabzon. This suggests it will be useful for health personnel working in the field of infant care to evaluate the traditional characteristics in the locations where they work and to correct negative

2016-03-01

Full Text Available Introduction: This study approaches the process of teaching-learning of a group of occupational therapy students to act in the care of mothers of babies at risk in the hospital context. It is linked to a community project, supported by the ‘Programa de Extensao Universitaria’. Objective: It aimed to qualify the students for understanding the risk rising, the initial mother-baby bond in the hospital environment, the monitoring of the child development and troubleshooting, as well as to see themselves as subjects of their own training. Method: Participants were six students, three teachers, 26 mothers and their 28 babies. The procedures had been developed in three articulated axles: practice, theoretical basis and invitation to reflection, each axle guided by one of three teachers. There were 65 meetings; 27 of the group of mothers, 11 of the group for theoretical overviews and 27 of the reflection group. Six students have completed their participation in the study, having achieved qualification for the care of occupational therapy to mothers of babies at risk during hospitalization and at home after discharge, as well as the co-responsibility with people and served family. All 26 mothers received care in the nursery; 25 of them in addition to the nursery, were treated at mothers group and 6 in addition to the nursery and the group, were visited at home. Conclusion: This study made it possible to contemplate two subjects with the same priority: the mother and her baby, as subjects of the attention and care of an occupational therapist and the student, as the subject of the attention and care of the teacher of occupational therapy.

2015-09-01

Teen pregnancy remains a public health problem of varying importance in developing and developed countries. There are risks and consequences for teen parents and the child on the medical and socioeconomic level. We conducted a literature search on multiple databases, focusing on the risk and the consequences of teen pregnancy and childbearing. We used different combined keywords as teen pregnancy, teen mother, teenage parents, teenage childbearing, teenage mother depression. Our search included different type of journals to have access on different views (medical, psychological, epidemiologic). The teen mothers are more at risk for postnatal depression, school dropout and bad socioeconomic status. The babies and children are more at risk for prematurity and low birthweight and later for developmental delays and behavior disorders. Pregnancy in adolescence should be supported in an interdisciplinary way (gynecologist, psychologist, child psychiatrist, midwives, pediatrician). We need further studies that allow targeting patients most at risk and personalizing maximum support.

Reich, Stephanie M; Penner, Emily K; Duncan, Greg J

2011-01-01

To determine whether educational baby books are an effective method for increasing low-income, first-time mothers' safety practices during their child's first 18 months. Primiparous women (n = 167) were randomly assigned to 1 of 3 groups: an educational book group, a noneducational book group, or a no-book group. Home visits and interviews measured safety practices when women were in their third trimester of pregnancy (baseline) and when their children were 2, 4, 6, 9, 12, and 18 months of age. Women in the educational book group had fewer risks in their homes and exercised more safety practices than the no-book group (- 20% risk reduction; effect size = -.30). When the safety practices involved little time or expense (eg, putting away sharp objects), the educational book group was significantly more likely to engage in these behaviors than the no-book group (40% higher practices; effect size = 0.19) or noneducational book group (27% higher practices; effect size = 0.13). However, no differences were found between groups for behaviors that required high effort in time, money, or hassle (eg, installing latches on cabinets). Educational baby books appear to be an easy and low-cost way to increase the safety practices of new mothers, especially if the practices involve little to no time, money, or hassle.

Campos, Viviani Jaques; Morais, Tania Beninga

2015-08-01

A homemade chicken liver baby food (CLBF) that meets infants' nutritional requirements was developed and its acceptance by children and their mothers determined. CLBF's nutritional content was determined by chemical analyses. A blind sensory test (ST) by 50 infants 7-12 months old and their mothers of CLBF and ground beef baby food (GBBF) was applied. Mothers' preferences for liver and beef, answers of an hedonic scale and infants' acceptance were investigated. CLBF met the nutritional requirements for infants. There were no significant differences in the ST between the CLBF and GBBF, either for infants or for their mothers. There was no correlation between mothers' like or dislike of liver and the ST scores. Infants tried and liked the CLBF that match dietary recommendations and could help prevent iron deficiency. Mothers, on the other hand, demonstrated an 'I don't like it; I never tried it' attitude. © The Author [2015]. Published by Oxford University Press. All rights reserved.

Support for healthy breastfeeding mothers with healthy term babies

Science.gov (United States)

Renfrew, Mary J; McCormick, Felicia M; Wade, Angela; Quinn, Beverley; Dowswell, Therese

2014-01-01

Background There is extensive evidence of important health risks for infants and mothers related to not breastfeeding. In 2003, the World Health Organization recommended infants be exclusively breastfed until six months of age, with breastfeeding continuing as an important part of the infant’s diet till at least two years of age. However, breastfeeding rates in many countries currently do not reflect this recommendation. Objectives To assess the effectiveness of support for breastfeeding mothers. Search methods We searched the Cochrane Pregnancy and Childbirth Group’s Trials Register (3 October 2011). Selection criteria Randomised or quasi-randomised controlled trials comparing extra support for healthy breastfeeding mothers of healthy term babies with usual maternity care. Data collection and analysis Two review authors independently assessed trial quality and extracted data. Main results Of the 67 studies that we assessed as eligible for inclusion, 52 contributed outcome data to the review (56,451 mother-infant pairs) from 21 countries. All forms of extra support analysed together showed an increase in duration of ‘any breastfeeding’ (includes partial and exclusive breastfeeding) (risk ratio (RR) for stopping any breastfeeding before six months 0.91, 95% confidence interval (CI) 0.88 to 0.96). All forms of extra support together also had a positive effect on duration of exclusive breastfeeding (RR at six months 0.86, 95% CI 0.82 to 0.91; RR at four to six weeks 0.74, 95% CI 0.61 to 0.89). Extra support by both lay and professionals had a positive impact on breastfeeding outcomes. Maternal satisfaction was poorly reported. Authors’ conclusions All women should be offered support to breastfeed their babies to increase the duration and exclusivity of breastfeeding. Support is likely to be more effective in settings with high initiation rates, so efforts to increase the uptake of breastfeeding should be in place. Support may be offered either by

Mother and newborn baby: mutual regulation of physiology and behavior--a selective review.

Science.gov (United States)

Winberg, Jan

2005-11-01

This article reviews 30 years of work demonstrating that interactions between mother and newborn infant in the period just after birth influence the physiology and behavior of both. Close body contact of the infant with his/her mother helps regulate the newborn's temperature, energy conservation, acid-base balance, adjustment of respiration, crying, and nursing behaviors. Similarly, the baby may regulate--i.e., increase--the mother's attention to his/her needs, the initiation and maintenance of breastfeeding, and the efficiency of her energy economy through vagus activation and a surge of gastrointestinal tract hormone release resulting in better exploitation of ingested calories. The effects of some of these changes can be detected months later. Parallels to animal research and possible mechanisms are discussed.

Baby M: babies (and justice) for sale.

Science.gov (United States)

Annas, G J

1987-06-01

A professor of health law criticizes the decisions of New Jersey Superior Court Judge Harvey R. Sorkow which culminated in his awarding permanent custody of Baby M to her biological father, William Stern. Annas quotes from the In re Baby M decision and from the contract between Stern and his wife and surrogate mother Mary Beth Whitehead to support his contention that Sorkow "rendered a sermon filled with contradictions, double-standards, inapt analogies, and unsupported conclusions." He argues that legally Mrs. Whitehead could not have prospectively waived her right to rear a child she bore, that Sorkow was biased in favor of the "upper-middle-class Sterns," and that consideration should be given to returning Baby M to Mrs. Whitehead. He urges state legislatures to outlaw the sale of children, to affirm the legal status of the gestational mother, and to forbid a surrogate's relinquishment of parental rights until after her child's birth.

Full Text Available INTRODUCTION: Linkage of HIV-infected pregnant women to HIV care remains critical for improvement of maternal and child outcomes through prevention of maternal-to-child transmission of HIV (PMTCT and subsequent chronic HIV care. This study determined proportions and factors associated with intra-facility linkage to HIV care and Early Infant Diagnosis care (EID to inform strategic scale up of PMTCT programs. METHODS: A cross-sectional review of records was done at 2 urban and 3 rural public health care facilities supported by the Infectious Diseases Institute (IDI. HIV-infected pregnant mothers, identified through routine antenatal care (ANC and HIV-exposed babies were evaluated for enrollment in HIV clinics by 6 weeks post-delivery. RESULTS: Overall, 1,025 HIV-infected pregnant mothers were identified during ANC between January and June, 2012; 267/1,025 (26% in rural and 743/1,025 (74% in urban facilities. Of these 375/1,025 (37% were linked to HIV clinics [67/267(25% rural and 308/758(41% urban]. Of 636 HIV-exposed babies, 193 (30% were linked to EID. Linkage of mother-baby pairs to HIV chronic care and EID was 16% (101/636; 8/179 (4.5%] in rural and 93/457(20.3% in urban health facilities. Within rural facilities, ANC registration <28 weeks-of-gestation was associated with mothers' linkage to HIV chronic care [AoR, 2.0 95% CI, 1.1-3.7, p = 0.019] and mothers' multi-parity was associated with baby's linkage to EID; AoR 4.4 (1.3-15.1, p = 0.023. Stigma, long distance to health facilities and vertical PMTCT services affected linkage in rural facilities, while peer mothers, infant feeding services, long patient queues and limited privacy hindered linkage to HIV care in urban settings. CONCLUSION: Post-natal linkage of HIV-infected mothers to chronic HIV care and HIV-exposed babies to EID programs was low. Barriers to linkage to HIV care vary in urban and rural settings. We recommend targeted interventions to rapidly improve linkage to

In view of the implementation of new care strategies for mothers of high-risk babies attended at neonatal units through a program involving play, recreation and educational activities, this study aims to analyze this experience according to these women's perspectives. A qualitative and descriptive study was conducted at the University Hospital of Ribeirão Preto, Brazil. Seven mothers were interviewed who had attended at least three activity sessions in the program and signed an informed consent document. The interviews were taped and were guided by the following question: "Tell us about your experience in these group meetings". It was observed that the mothers described the activities as "...they are nice and help to establish ties" and "...they are good because we get some distraction", thus revitalizing them to cope with the stress from long hospitalization. They pointed out the opportunity to learn about some types of care for their children through games and educational films -- "They solve many of our doubts, especially for those who have pre-term babies", as well as the opportunity to do manual work -- "We learned how to embroider, which was something no one knew how to do". This activity resulted in the production of clothing for the child. It was concluded that the program contributed to the process of constructing a more integral and humanized care by focusing on the family and broadening the perspective on hospitals as places that also offer leisure.

Full Text Available Introduction: Involving the parents in caring of premature newborns is one of the best and effective manners for preventing the hospitalization of premature newborns. The present study aimed to evaluate the effect of mother – baby skin- to- skin care on neonatal outcomes in preterm infants, in Kosar hospital. Methods: This was a descriptive comparative study conducted on 400 nulliparous women with premature infants admitted to neonatal intensive care unit of Kosar hospital during April 2012 and March 2015. Sampling was performed via convenience sampling. Sample population divided into two groups, one of them 200, the kangaroo care and non- care groups. The data were obtained by a researcher prepared check list, including mother’s demographic characteristics and neonatal outcomes. Both descriptive and statistical analysis methods were applied. For analyzing the data, chi-square test, t-test, and logistic regression tests was applied (P 0.05. In the intervention group, the relationship between maternal variables and neonatal outcome was significant (P <0.05. Conclusion: Mother – baby skin- to- skin care has a positive effect on neonatal outcomes. Thus, supporting and awareness of premature infants’ mothers in order to implement this type of care can reduce the neonatal complications. Moreover, it is effective in decreasing the treatment costs.

To describe the clinical population of women admitted to a Mother-Baby Unit in Adelaide, South Australia and to evaluate changes during admission in both Axes I and II diagnoses of maternal mental health, and in mother-infant relationships. Both clinical and self-report assessments of maternal mental health were made at admission and discharge, and self-report comparisons of the mother-infant relationship. Depressive illnesses (46.2%) were found to be the most prevalent conditions leading to admission, with rates of psychosis (10.3%) and bipolar disorder (3.4%) being lower. A high incidence of borderline personality disorder (23.1%) was found clinically, with almost half the admitted women showing features of borderline personality disorder on a self-report measure at admission. Significant improvements in maternal mental health and the mother-infant relationship were found at the time of discharge. Admission to this Mother-Baby Unit on mothers' self-report scales showed improvement in mothers' mental health and the relationship that they have with their infant. Given the high prevalence of borderline personality disorder and emotional dysregulation identified within the population, treatment implications and possible consequences for the infant are discussed for this client group. © The Royal Australian and New Zealand College of Psychiatrists 2015.

Hepatitis B (HBV) in sub-Saharan Africa is believed to be horizontally acquired. However, because of the high HBV prevalence in northern Uganda, no hepatitis B vaccination at birth and no access to HBV immunoglobulin, we hypothesize that vertical transmission also could also play an important role. We therefore investigated the incidence of HBV among babies presenting for their first HBV vaccine dose in Gulu, Uganda. We recruited mothers and their babies (at least 6-week old) presenting for their postnatal care and first HBV vaccine dose respectively. Socio-demographic and risk factors for HBV transmission were recorded. Mothers were tested for Hepatitis B core antibody (anti-HBc-IgG) and hepatitis B surface antigen (HBsAg). HBsAg-positive sera were tested for hepatitis B e antigen (HBeAg) and HBV viral load (HBVDNA). Babies were tested for HBsAg at presentation and at the last immunization visit. A sample of HBsAg-negative babies were tested for HBVDNA. Incident HBV infection was defined by either a positive HBsAg or HBVDNA test. Chi-square or fisher's exact tests were utilized to investigate associations and t-tests or Wilcoxon rank-sum test for continuous differences. We recruited 612 mothers, median age 23years (IQR 20-28). 53 (8.7%) were HBsAg-positive and 339 (61.5%) were anti-HBc-IgG-positive. Ten (18.9%) of the HBsAg-positive mothers were HBeAg-positive. Median HBVDNA levels of HBV-infected mothers was 5.7log (IQR 4.6-7.0) IU/mL with 9 (17.6%) having levels≥10 5 IU/mL. Eighty (13.3%) mothers were HIV-infected of whom 9 (11.5%) were co-infected with HBV. No baby tested HBsAg or HBVDNA positive. Vertical transmission does not seem to contribute substantially to the high HBV endemicity in northern Uganda. The current practice of administering the first HBV vaccine to babies in Uganda at six weeks of age may be adequate in control of HBV transmission. Copyright © 2017 Elsevier Ltd.

High baby birth weight and risk of hormone-associated cancer in mothers: the cancer-cardiovascular disease dichotomy and its possible causes.

Science.gov (United States)

Berstein, Lev M

2013-07-01

The idea of intrauterine or fetal factors being the cause of several prevalent noninfectious diseases in adults has recently gained the status of an axiom. One of the most thoroughly studied predictors is birth weight (BW). Although many published studies point at relations between BW and later adult morbidity or mortality, much less attention is paid to associations between baby BW and maternal morbidity. Available data suggest a sort of dichotomy in these relationships. Thus, cardiovascular risk is higher in mothers of babies with a reduced BW, while cancer risk, mainly of the breast and some other hormone-dependent cancers, is often higher among mothers of babies with a large BW (newborn macrosomia). This review addresses possible causes and endocrine mechanisms of this topic and suggests a 'particular' and 'general' solution for arising controversy. Emphasis is placed on a probable competition between chronic diseases (mainly, between female hormone-related cancer and cardiovascular pathology) within the concept of multiple causes of death. These associations should be remembered while studying the relation between offspring BW and maternal predisposition to hormone-associated cancers and other noncommunicable diseases.

Comparative Analysis of Baby Food Labelling in Hungary and in Romania: Consumers’ Perspective

2018-02-01

Full Text Available Baby food represents a growing segment of the food industry; the baby food labelling issues affect more and more mothers who want to make better and safer nutritional choices. In a continuously improving food labelling regulation environment consumer studies regarding the baby food labelling are very limited. Present article has an exploratory nature and aims to find specific patterns of baby food buying behaviour and labelling preference in Romania and Hungary, and also to reveal the behavioural similarities and differences between the two countries. To meet this aim, a questionnaire-based quantitative research was designed. The sample consists of 993 mothers (590 from Hungary and 403 from Romania with small children. Results show that there is a difference between Romanian and Hungarian mothers regarding the baby food buying habits. The profile of the mothers buying jarred baby food can be characterised by living in towns, with one or two children, and the propensity to give jarred baby food to their child is growing with their age. The mothers agree that the labels contain tiny, unreadable letters, disordered information, unknown expressions and bad translation. The Hungarian mothers pay more attention to the indication of allergen and to the ingredients list. The most important information cluster they seek on a label is related to product ingredients, the second is related to usage of baby food and the least important are the label design elements. The paper provides insightful results for the producers and policy-makers to improve the baby food label quality to help consumers to make better, healthier and safer food choices for their children.

Auger, Anamarie; Reich, Stephanie M.; Penner, Emily K.

2014-01-01

The impact of a baby book intervention on promoting positive reading beliefs and increasing reading frequency for low-income, new mothers (n = 167) was examined. The Baby Books Project randomly assigned low-income, first-time mothers to one of three study conditions, receiving educational books, non-educational books, or no books, during pregnancy and over the first year of parenthood. Home-based data collection occurred through pregnancy until 18 months post-partum. Mothers who received free baby books had higher beliefs about the importance of reading, the value of having resources to support reading, and the importance of verbal participation during reading. The results showed that providing any type of baby books to mothers positively influenced maternal reading beliefs, but did not increase infant-mother reading practices. Maternal reading beliefs across all three groups were significantly associated with self-reported reading frequency when children were at least 12 months of age. PMID:25264394

Previous cross-diagnosis studies of interaction between mothers with severe mental illness and their babies have concluded that mothers with schizophrenia have deficits in interaction, but these studies have not included healthy controls. In-patients on a mother and baby unit, with diagnoses of schizophrenia (n=15), depressive mood disorders with or without psychosis (n=23), or mood disorders where mania was the predominant feature, with or without psychosis (n=12), were observed interacting with their infants on admission and discharge. Mothers' mind-mindedness and other measures of the quality of maternal and infant behaviour were coded. Findings from this sample were compared with those from healthy mothers and their infants (n=49). Compared with healthy controls, on admission depressed mothers were marginally less likely to comment appropriately on their infants' mental states. Both the depressed and mania groups were more likely to touch their babies and engage in attention-seeking behaviours. Interactional behaviours of mothers in the schizophrenia group were not markedly different from healthy controls. On discharge there were fewer differences between the clinical and healthy groups, although the depressed group continued to engage in more attention-seeking and touching behaviour and the mania group continued to touch their infants more. Only mothers in the schizophrenia group showed changes in interactional behaviours between admission and discharge, talking more to their infants. The findings challenge previous conclusions that mothers with schizophrenia have deficits in their interactions with their babies, and demonstrate that mothers with severe mental illness are able to respond appropriately to their infants' cues.

[Attachment theory and baby slings/carriers: technological network formation].

Science.gov (United States)

Lu, Zxy-Yann Jane; Lin, Wan-Shiuan

2011-12-01

Healthcare providers recognize the important role played by attachment theory in explaining the close relationship between mental health and social behavior in mothers and their children. This paper uses attachment theory in a socio-cultural context to ascertain the mechanism by which baby slings/carriers, a new technology, produced and reproduced the scientific motherhood. It further applies a social history of technology perspective to understand how baby carriers and attachment theory are socially constructed and historically contingent on three major transformations. These transformations include the use of attachment theory-based baby carriers to further scientific motherhood; the use of baby slings/carriers to further the medicalization of breastfeeding and enhance mother-infant attachment; and the use of baby slings/carriers to transform woman's identities by integrating scientific motherhood, independence and fashion. Implications for nursing clinical policy are suggested.

Reaching mothers and babies with early postnatal home visits: the implementation realities of achieving high coverage in large-scale programs.

Directory of Open Access Journals (Sweden)

Deborah Sitrin

Full Text Available BACKGROUND: Nearly half of births in low-income countries occur without a skilled attendant, and even fewer mothers and babies have postnatal contact with providers who can deliver preventive or curative services that save lives. Community-based maternal and newborn care programs with postnatal home visits have been tested in Bangladesh, Malawi, and Nepal. This paper examines coverage and content of home visits in pilot areas and factors associated with receipt of postnatal visits. METHODS: Using data from cross-sectional surveys of women with live births (Bangladesh 398, Malawi: 900, Nepal: 615, generalized linear models were used to assess the strength of association between three factors - receipt of home visits during pregnancy, birth place, birth notification - and receipt of home visits within three days after birth. Meta-analytic techniques were used to generate pooled relative risks for each factor adjusting for other independent variables, maternal age, and education. FINDINGS: The proportion of mothers and newborns receiving home visits within three days after birth was 57% in Bangladesh, 11% in Malawi, and 50% in Nepal. Mothers and newborns were more likely to receive a postnatal home visit within three days if the mother received at least one home visit during pregnancy (OR2.18, CI1.46-3.25, the birth occurred outside a facility (OR1.48, CI1.28-1.73, and the mother reported a CHW was notified of the birth (OR2.66, CI1.40-5.08. Checking the cord was the most frequently reported action; most mothers reported at least one action for newborns. CONCLUSIONS: Reaching mothers and babies with home visits during pregnancy and within three days after birth is achievable using existing community health systems if workers are available; linked to communities; and receive training, supplies, and supervision. In all settings, programs must evaluate what community delivery systems can handle and how to best utilize them to improve postnatal care

The Baby-Friendly Hospital Initiative requires hospitals to pay market price for infant formula. No studies have specifically examined the effect of hospitals paying for infant formula on breastfeeding mothers' exposure to Baby-Friendly steps. To investigate the effect of hospitals implementing a policy of paying for infant formula on new mothers' exposure to Baby-Friendly steps and examine the effect of exposure to Baby-Friendly steps on breastfeeding rates. We used a repeated prospective cohort study design. We recruited 2 cohorts of breastfeeding mother-infant pairs (n = 2470) in the immediate postnatal period from 4 Hong Kong public hospitals and followed them by telephone up to 12 months postpartum. We assessed participants' exposure to 6 Baby-Friendly steps by extracting data from the medical record and by maternal self-report. After hospitals began paying for infant formula, new mothers were more likely to experience 4 out of 6 Baby-Friendly steps. Breastfeeding initiation within the first hour increased from 28.7% to 45%, and in-hospital exclusive breastfeeding rates increased from 17.9% to 41.4%. The proportion of mothers who experienced all 6 Baby-Friendly steps increased from 4.8% to 20.5%. The risk of weaning was progressively higher among participants experiencing fewer Baby-Friendly steps. Each additional step experienced by new mothers decreased the risk of breastfeeding cessation by 8% (hazard ratio = 0.92; 95% CI, 0.89-0.95). After implementing a policy of paying for infant formula, breastfeeding mothers were exposed to more Baby-Friendly steps, and exposure to more steps was significantly associated with a lower risk of breastfeeding cessation. © The Author(s) 2015.

To investigate the impact of maternal age on pregnancy outcomes with special emphasis on adolescents and older mothers and to investigate the differences in demographic profile between adolescents and older mothers. This study is a secondary analysis of pregnancy outcomes of women in Riyadh Mother and Baby cohort study according to maternal age. The study population was grouped according to maternal age into five subgroups; mothers were married when conceived with the index pregnancy. Young mothers were less likely to be illiterate, more likely to achieve higher education and be employed compared with mothers ≥ 40 years. Compared with the reference group, adolescents were more likely to have vaginal delivery (and least likely to deliver by caesarean section (CS); OR=0.6, 95% CI 0.4 to 0.9, while women ≥40 years, were more likely to deliver by CS; OR 2.9, 95% CI 2.3 to 3.7. Maternal age was a risk factor for gestational diabetes in women ≥40 years; OR 1.7, 95% CI 1.3 to 2.1. Adolescents had increased risk of preterm delivery; OR 1.5, 95% CI 1.1 to 2.1 and women ≥40 years had similar risk; OR, 1.3, 95% CI 1.1 to 1.6. Adverse pregnancy outcomes show a continuum with the advancement of maternal age. Adolescents mother are more likely to have vaginal delivery; however, they are at increased risk of preterm delivery. Advanced maternal age is associated with increased risk of preterm delivery, gestational diabetes and CS. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Maternal psychological factors like depression, anxiety and stress have been associated with infant fussiness or colic. However, little research exists on whether positive factors such as social support and the happiness of the mother-partner relationship are associated with lower rates of infant fussiness or colic. We investigated the association between infant colic and three types of maternal support: general maternal social support (during pregnancy and post partum), the happiness of the mother-partner relationship (during pregnancy and post partum) and partner involvement in caring for the newborn. Participants were 3006 women in the First Baby Study, a prospective study of the effect of mode of first delivery on subsequent childbearing. Women were interviewed by telephone during pregnancy and 1 month after first childbirth and asked about social support and if their baby had a variety of problems since birth, including 'Colic - crying or fussiness three or more hours a day'. Multivariable logistic regression models were used to model the association between maternal support and infant colic, controlling for confounders, including maternal race or ethnicity, insurance, marital status, smoking, mode of delivery, maternal post-partum depression, breastfeeding, other neonatal illnesses and newborn gestational age. Infant colic was reported by 11.6% of new mothers. High general maternal social support (in comparison with low), measured during pregnancy, was associated with lower reported infant colic (adjusted odds ratio (AOR), 0.55, 95% confidence interval (CI), 0.40-0.75) and measured post partum (AOR, 0.51, 95% CI, 0.39-0.67); high relationship happiness (in comparison with low), measured during pregnancy (AOR, 0.71, 95% CI, 0.54-0.93), and measured post partum (AOR, 0.22, 95% CI, 0.12-0.40); and high partner involvement with newborn care (in comparison with low) (AOR, 0.60, 95% CI, 0.44-0.81).

Haul truck tire dynamics due to tire condition

Anzabi, R Vaghar; Nobes, D S; Lipsett, M G

2012-01-01

Pneumatic tires are costly components on large off-road haul trucks used in surface mining operations. Tires are prone to damage during operation, and these events can lead to injuries to personnel, loss of equipment, and reduced productivity. Damage rates have significant variability, due to operating conditions and a range of tire fault modes. Currently, monitoring of tire condition is done by physical inspection; and the mean time between inspections is often longer than the mean time between incipient failure and functional failure of the tire. Options for new condition monitoring methods include off-board thermal imaging and camera-based optical methods for detecting abnormal deformation and surface features, as well as on-board sensors to detect tire faults during vehicle operation. Physics-based modeling of tire dynamics can provide a good understanding of the tire behavior, and give insight into observability requirements for improved monitoring systems. This paper describes a model to simulate the dynamics of haul truck tires when a fault is present to determine the effects of physical parameter changes that relate to faults. To simulate the dynamics, a lumped mass 'quarter-vehicle' model has been used to determine the response of the system to a road profile when a failure changes the original properties of the tire. The result is a model of tire vertical displacement that can be used to detect a fault, which will be tested under field conditions in time-varying conditions.

The result is a model of tire vertical displacement that can be used to detect a fault, which will be tested under field conditions in time-varying conditions.

To determine changes in the breastfeeding practices of mothers after receiving counseling on Ten Steps to Successful Breastfeeding as defined by the Baby Friendly Hospital Initiative comparing baby friendly hospitals (BFHs) and non-baby-friendly hospitals in Sindh, Pakistan. Methods: The observational study was conducted from June 2007 to June 2009 in randomly selected baby-friendly and non-baby-friendly hospitals of Sindh, Pakistan. Non-probability purposive sampling was employed. The maternity staff was trained on Ten Steps to Successful Breastfeeding. The changes in breastfeeding practices were analysed by SPSS version 15. Results: A total of 236 women were included in the study. Of them, 196 (83.05%) were from baby-friendly hospitals and 40 (16.94%) from non-baby-friendly hospitals. Besides, 174 (88.7%) mothers in baby-friendly hospitals and 5 (12.5%) in non-baby-friendly hospitals during antenatal care received counseling by healthcare providers. There was an increase in breastfeeding practice up to 194 (98.97%) in the first category compared to 12 (30%) in the other category. Conclusion: Counseling under the Baby Friendly Hospital Initiative improved breastfeeding practices up to 98.97% in baby-friendly compared to non-baby-friendly hospitals. (author)

Asnani, Vivake M.; Benzing, Jim; Kish, Jim C.

2011-01-01

The spring tire is made from helical springs, requires no air or rubber, and consumes nearly zero energy. The tire design provides greater traction in sandy and/or rocky soil, can operate in microgravity and under harsh conditions (vastly varying temperatures), and is non-pneumatic. Like any tire, the spring tire is approximately a toroidal-shaped object intended to be mounted on a transportation wheel. Its basic function is also similar to a traditional tire, in that the spring tire contours to the surface on which it is driven to facilitate traction, and to reduce the transmission of vibration to the vehicle. The essential difference between other tires and the spring tire is the use of helical springs to support and/or distribute load. They are coiled wires that deform elastically under load with little energy loss.

Mothers say "baby" and their newborns do not choose to listen: a behavioral preference study to compare with ERP results

Christine M Moon

2015-03-01

Full Text Available Previously published results from neonatal brain evoked response potential (ERP experiments revealed different brain responses to the single word baby depending on whether it was recorded by the mother or an unfamiliar female. These results are consistent with behavioral preference studies in which infants altered pacifier sucking to contingently activate recordings of the maternal vs. an unfamiliar female voice, but the speech samples were much longer and information-rich than in the ERP studies. Both types of neonatal voice recognition studies imply postnatal retention of prenatal learning. The preference studies require infant motor and motivation systems to mount a response in addition to voice recognition. The current contingent sucking preference study was designed to test neonatal motivation to alter behavior when the reward is the single word baby recorded by the mother or an unfamiliar speaker. Results showed an absent or weak contingent sucking response to the brief maternal voice sample, and they demonstrate the complementary value of electrophysiological and behavioral studies for very early development. Neonates can apparently recognize the maternal voice in brief recorded sample (previous ERP results but they are not sufficiently motivated by it to alter sucking behavior.

Full Text Available The purpose of this study was to examine first-time mothers' postpartum stress and its correlates following discharge from the hospital or clinic after vaginal delivery. One hundred and eightythree first-time mothers were enrolled from hospitals and clinics in Kaohsiung City. All first-time mothers reported normal pregnancies and vaginal deliveries, delivered healthy infants at term, and were surveyed during their postpartum periods after discharge from hospitals or clinics. The Hung Postpartum Stress Scale was used to examine first-time mothers' postpartum stress and stressors during their postpartum periods. The top ten postpartum stressors perceived by the women were: “the baby getting sick suddenly”, “the flabby flesh of my belly”, “the unpredictability of the baby's schedule”, “interrupted sleep”, “the shape of the baby's head due to the sleeping position”, “not sleeping enough”, “lack of information regarding infant's growth and development”, “the baby's crying”, “my life is restricted”, and “the baby choking during feeding”. There were no significant differences between the first-time mothers' demographic characteristics and their postpartum stress and its three components (negative body changes, maternal role attainment, lack of social support, respectively. Insight into the study results of first-time mothers' post- partum stress and stressors provides a reference for health professionals that the development of programs and resources addressing primiparous women's unique needs are required.

The relationship between mother and baby is of fundamental importance in the development of cognitive function and emotion. In this study we investigated the effects of affective photographs of a mother and baby (crying or smiling faces) and other stimuli (neutral mother or baby faces) on visual cognitive function in schizophrenic patents. We recorded exploratory eye movements in 22 healthy controls and 22 age-matched schizophrenic patients. Total number of right and left field gaze points (right TNGP, left TNGP) in the visual fields were determined using an eye-mark recorder as subjects viewed affectively charged or neutral photographs (crying, smiling or neutral faces). Left TNGP for all mother photographs (crying, smiling or neutral) were significantly larger in controls than patients, and right TNGP for neutral mother photographs were significantly larger in controls than in patients. Right TNGP for photographs of smiling babies were significantly larger in controls than patients, and left TNGP for photographs of both smiling and crying babies were significantly larger in controls than patients. Within the patient group, right TNGP were significantly larger than left TNGP for all mother photographs (crying, smiling or neutral). Left TNGP for photographs of mothers and babies correlated negatively with negative symptom scores. These results suggest that exploratory eye movements when viewing emotionally laded twin stimuli such as photographs of a mother and baby are a useful marker of visual cognitive function in both healthy controls and schizophrenic patients.

Full Text Available Introduction: The prevalence of Low Birth Weight (LBW is higher in Asia than elsewhere predominantly because of undernutrition and poor socioeconomic status of mothers. Nearly half of the pregnant women still suffer from varying degrees of anaemia with the highest prevalence in India. Optimal weight gain during pregnancy and a desirable foetal outcome in terms of normal birth weight of the baby may be a result of synergistic effect of literacy, knowledge, improved food intake, and higher level of socioeconomic status of the pregnant women and their family. Aim: To observe the influence of maternal nutritional, socioeconomic status and literacy level on birth weight of babies. Materials and Methods: Total 250 mothers who delivered babies and admitted to the post natal ward of B.S.T. Rural Hospital, Talegaon Dabhade, District Pune, Maharashtra, India, were randomly selected and the relevant information was recorded in self prepared and pre validated questionnaire. Dietary history was collected by 24 hours recall method. Results: A total of 250 mothers and their babies were included. The average birth weight of babies was 2.65 Kg with the lowest birth weight of 1.2 Kg while the highest birth weight of 4 Kg. The prevalence of LBW babies was 27.6%. Most of the women (77.2% had caloric intake less than 1800 Kcal, 80% of mothers had protein intake of less than 45 gm. Nearly, 31.60% of women who were taking daily intake of calories less than 1800 Kcal delivered LBW babies. About 30.50% of the women with protein intake less than 45 gm/ day delivered LBW babies. In all 34.86% of the women with hemoglobin level below 11 gm% delivered LBW babies. These findings were statistically significant. Conclusion: Maternal caloric and protein deficiencies including anaemia during pregnancy had direct effect on the birth weight of newborns, as less nourished mothers were found to deliver higher percentage of LBW babies as compared to the mothers who were better

Neonatal jaundice is the commonest abnormal physical finding in the new born nursery and hemolytic disease of the newborn (HDN) among babies born to Rh negative mothers is the most formidable etiology. During last few decades considerable evolution has been observed in this entity secondary to development of several novel preventive, diagnostic and therapeutic modalities. To study the current trends in presentation, management and outcome of hyperbilirubinemia among newborns delivered to Rh negative mothers. This observational descriptive study with prospective data collection included one hundred live born term babies born to Rh negative mothers in our hospital. A predesigned proforma was used to record antenatal and postnatal data .Cord blood collected during delivery for assessment of bilirubin,hematocrit and direct coombs test.Serum bilirubin levels were estimated in babies with clinical jaundice and treated for the same if required.All babies were regularly followed up weekly for one month. Chi square test/Fisher Exact test and Student "t" test has been used to find the significant association of jaundice(incidence,treatment) and study characteristics. Out of 100 babies enrolled, 57 babies developed jaundice. Jaundice is 2.7 times more likely associated with babies born to multiparous Rh-ve mothers with p=0.017*. Jaundice is 3 times more likely associated with Rh+ve babies born to multiparous mothers with p=0.020*. Jaundice is 3.97 times more likely associated with Rh+ve babies born to multiparous mothers who have not received Anti-D with p=0.154. Treatment of jaundice is 2.75 times more likely in Rh+ve babies born to multiparous mothers who have not received Anti-D with p=0.162. Duration of phototherapy is significantly more in Rh+ve babies born to multiparous mothers who had not received Anti-D with p=0.0097*.Exchange transfusion was required in two babies. Although the incidence of Rh isoimmunization has declined dramatically over the years ,it is still an

Preterm babies are more prone to develop disorders and so require immediate intensive care. In the conventional neonatal intensive care, the baby is kept in the incubator, separated from the mother. Some actions have been taken in order to make this mother-child separation less traumatic. One of these actions is the Kangaroo mother care (KMC) characterized by skin-to-skin contact between a mother and her newborn. The objective of this study was to compare the mood variation of mothers enrolled in the KMC program to those in the conventional incubator care. In one general hospital in Sao Paulo, Brazil, 90 mothers were evaluated before and after contact with the baby in the Neonatal Intensive Care Unit. The participants were divided into three groups: 30 mothers of term newborns (TG), 30 mothers of preterm infants included in KMC program (PGK) and 30 preterms with incubator placement (PGI). The Brazilian version of the Visual Analogue Mood Scale (VAMS) was used for the assessment before and after the infant's visit. Results showed that TG mothers reported fewer occurrences of depressive states than PGK and PGI mothers. A significant mood variation was observed for PGK and PGI after the infant's visit. PGK mothers reported feeling calmer, stronger, well-coordinated, energetic, contented, tranquil, quick-witted, relaxed, proficient, happy, friendly and clear-headed. The only variation showed by PGI mothers was an increase in feeling clumsy. This study shows a positive effect of the KMC on the mood variation of preterm mothers and points to the need of a more humane experience during the incubator care.

The purpose of this descriptive qualitative study was to gain understanding of perceptions of low-income pregnant women and mothers about parenting. Participants were 65 low-income, primarily African American, women in their 20s and 30s who were recruited from a faith-based social service center in Memphis, Tennessee. Interviews were conducted by nursing, social work, and psychology students. The existential phenomenological method was used to analyze verbatim responses of participants to vignettes depicting parenting behaviors of hypothetical mothers. Five global themes were identified: (a) Focus on baby's development: "Because I'm the Mother, I'm the First Teacher"; (b) Focus on baby's safety/security: "The Baby Could Be Hurt"; (c) Focus on conveying love: "She Just Wants the Baby to Feel Her Love"; (d) Focus on learning the rules of good childcare: "It's Important to Know the Do's and Don'ts"; and (e) Focus on doing it differently (better) than parents did: "When You Know Better, You Do Better." Findings suggest that these mothers care deeply about providing a better life for their children than the life they have had. They desire to learn about being the best parents they can be. As nurses, we can help to provide educational opportunities for mothers through a variety of evidence-based interventions delivered across the childbearing years.

Immunity to diphtheria has been noted to wane with age such that previous studies have shown that a significant proportion of females with characteristics comparable to those of Nigerian women of reproductive age have inadequate levels of immunity to diphtheria. Thus, it is envisaged that Nigerian newborns may inherit inadequate levels of immunity to diphtheria from their mothers. Cord blood and peripheral maternal blood samples were collected from 231 mother-infant pairs at delivery. Anti-diphtheria antibody titres were assayed using Enzyme-linked immunosorbent assay (ELISA) technique. Recruited babies were those born at term with normal birth weight. As much as 29.9% of both mothers and their babies had no protection (antibody titrediphtheria. Ninety (39.0% CI 33%,45%) mothers and 107 (46.3% CI 40%,52%) babies were inadequately protected (antibody titrediphtheria. The difference in the geometric mean antibody titres of mothers and babies was statistically significant (pdiphtheria.

Kenanga Purbasary, Eleni; Rustina, Yeni; Budiarti, Tri

Mothers giving birth to low birth weight babies (LBWBs) have low confidence in caring for their babies because they are often still young and may lack the knowledge, experience, and ability to care for the baby. This research aims to determine the effect of education about kangaroo mother care (KMC) on the confidence and ability of young mothers to implement KMC. The research methodology used was a controlled-random experimental approach with pre- and post-test equivalent groups of 13 mothers and their LBWBs in the intervention group and 13 mothers and their LBWBs in the control group. Data were collected via an instrument measuring young mothers' confidence, the validity and reliability of which have been tested with a resulting r value of .941, and an observation sheet on KMC implementation. After conducting the education, the confidence score of young mothers and their ability to perform KMC increased meaningfully. The score of confidence of young mothers before education was 37 (p = .1555: and the ability score for KMC Implementation before education was 9 (p = .1555). The median score of confidence of young mothers after education in the intervention group was 87 and in the control group was 50 (p = .001, 95% CI 60.36-75.56), and ability median score for KMC implementation after education in the intervention group was 16 and in the control group was 12 (p = .001, 95% CI 1.50-1.88). KMC education should be conducted gradually, and it is necessary to involve the family, in order for KMC implementation to continue at home. A family visit can be done for LBWBs to evaluate the ability of the young mothers to implement KMC.

Kristjana Einarsdóttir

Full Text Available BACKGROUND: The Australian baby bonus maternity payment introduced in 2004 has been reported to have successfully increased fertility rates in Australia. We aimed to investigate the influence of the baby bonus on maternal demographics and birth characteristics in Western Australia (WA. METHODS AND FINDINGS: This study included 200,659 birth admissions from WA during 2001-2008, identified from administrative birth and hospital data-systems held by the WA Department of Health. We estimated average quarterly birth rates after the baby bonus introduction and compared them with expected rates had the policy not occurred. Rate and percentage differences (including 95% confidence intervals were estimated separately by maternal demographics and birth characteristics. WA birth rates increased by 12.8% following the baby bonus implementation with the greatest increase being in mothers aged 20-24 years (26.3%, 95%CI = 22.0,30.6, mothers having their third (1.6%, 95%CI = 0.9,2.4 or fourth child (2.2%, 95%CI = 2.1,2.4, mothers living in outer regional and remote areas (32.4%, 95%CI = 30.2,34.6, mothers giving birth as public patients (1.5%, 95%CI = 1.3,1.8, and mothers giving birth in public hospitals (3.5%, 95%CI = 2.6,4.5. Interestingly, births to private patients (-4.3%, 95%CI = -4.8,-3.7 and births in private hospitals (-6.3%, 95%CI = -6.8,-5.8 decreased following the policy implementation. CONCLUSIONS: The introduction of the baby bonus maternity payment may have served as an incentive for women in their early twenties and mothers having their third or fourth child and may have contributed to the ongoing pressure and staff shortages in Australian public hospitals, particularly those in outer regional and remote areas.

Liddle, Mitzi-Jane E; Bradley, Ben S; Mcgrath, Andrew

2015-01-01

Empathy is an important competence in our social world, a motivator of prosocial behavior, and thought to develop throughout the second year of life. The current study examined infants' responses to naturalistic peer distress to explore markers of empathy and prosocial behavior in young babies. Seventeen 8-month-old infants participated in a repeated measures design using the "babies-in-groups" paradigm, with maternal presence as the independent variable. Significant differences were found between response types: Gaze was the standard response to infant distress, followed by socially directed behaviors and affect, with self-distress rarely occurring. Maternal presence was not found to impact the nature or frequency of babies' responses to peer distress. During distress episodes, babies looked preferentially at the distressed peer, then other mothers, and least to their own mother. Data revealed that infant responses to peer distress resulted in a successful cessation of that distress episode over one third of the time. Case studies are provided to illustrate the quantitative data. The results provided evidence of empathic concern and prosocial behavior in the first year of life, and provoke a challenge to developmental theories of empathy. © 2015 Michigan Association for Infant Mental Health.

2017-06-01

Skin provides several important homeostatic functions to the developing neonate. However, no consensus guidelines exist in the United States for skin care in the healthy term newborn. We performed a study of skin and umbilical cord care (including bathing practices, vernix removal and antiseptic cord application) in newborn nurseries and mother-baby units throughout the state of Maryland to determine practices in a variety of clinical settings and assess if uniformity in skin care exists. These data were then assessed in the context of a review of the current literature. We received responses from over 90% of nurseries across the state. In our cohort, practices varied widely between institutions and specific populations, and often were not evidence-based or were contrary to best practices discussed in the scientific literature. The frequent departures from evidence that occur regarding the aforementioned practices are likely due to a lack of consensus on these issues as well as limited data on such practices, further highlighting the need for data-driven guidelines on newborn skin care.

As Baby Boomers enter late life, relationships with family members gain importance. This review article highlights two aspects of their intergenerational relationships: (a) caregiving for aging parents and (b) interactions with adult children in the context of changing marital dynamics. The researchers describe three studies: (a) the Within Family Differences Study (WFDS) of mothers aged 65-75 and their multiple grown children (primarily Baby Boomers) ongoing since 2001; (b) the Family Exchanges Study (FES) of Baby Boomers aged 42-60, their spouses, parents, and multiple grown children ongoing since 2008; and (c) the Longitudinal Study of Generations (LSoG) of 351 three-generation families started when the Baby Boomers were teenagers in 1971, with interviews every 3-5 years from 1985 to 2005. These studies show that the Baby Boomers in midlife navigate complex intergenerational patterns. The WFDS finds aging parents differentiate among Baby Boomer children in midlife, favoring some more than others. The FES shows that the Baby Boomers are typically more involved with their children than with their aging parents; Boomers' personal values, family members' needs, and personal rewards shape decisions about support. The LSoG documents how divorce and remarriage dampen intergenerational obligations in some families. Moreover, loosening cultural norms have weakened family bonds in general. Reviews of these studies provide insights into how the Baby Boomers may negotiate caregiving for aging parents as well as the likelihood of family care they will receive when their own health declines in the future.

A 9-Year-Old Girl Discovers That Her Mother Was Murdered.

Science.gov (United States)

Schonfeld, David J; Shekunov, Julia; Jellinek, Michael; Stein, Martin T

Susan was a 9-year-old girl living with her mother; she had never met her father. Her mother returned one evening from her job as a cocktail waitress and Susan met her at the apartment door to let her know they had run out of cat food. Her mother said she would go and buy some the next morning because it was late and she was tired, but Susan insisted she go out that evening because the cat had not eaten all day. Her mother was fatally shot in the parking lot of the convenience store shortly thereafter; since there was no robbery involved, the police suspected it was someone that she knew. Susan's extended family had her move out of the apartment that evening and relocate to live with her aunt and uncle out-of-state. The transition happened quickly. Susan was unable to return to her apartment to pick up any additional belongings and never returned to say goodbye to her friends. The family decided she was too young to attend the funeral.Susan had trouble fitting in with her aunt and uncle's family; they had 2 children who were 8 and 6 years old, and Susan felt she was being treated like a baby. She resented having a bedtime (her mother allowed her to stay up as late as she wished), and she complained that the work at school was boring and her classmates were childish. When the family went to a festival in town, she left abruptly without telling them, which frightened Susan's aunt and uncle. They wanted to be supportive but felt that she needed more structure than her mother had provided her. Susan's aunt and uncle sought bereavement support for Susan from her pediatrician and parenting advice for themselves.

DEMOGRAPHIC-ANAMNESTIC PARAMETERS WHICH AFFECT IMPLEMENTATION OF BABY FRIENDLY PROGRAM

Directory of Open Access Journals (Sweden)

2005-12-01

Full Text Available Various studies and extensive researches, particularly during recent years, on the advantages of breastfeeding and the use of breast milk in infant`s nourishment, have stressed its immeasurable benefit to mothers, infants, family and society. The objective of the research was to ascertain demographic and anamnestic factors affecting the implementation of the baby friendly program. The study was undertaken at OGC CC Kragujevac and based on data from 432 women. The mean age of the examinees was 25,9 years and they were 6 months younger than the corresponding examinees from similar world researches. In most cases, the examinees were from urban areas and lived in bigger families, which did not affect the implementation of the program. With equal probability, it was the first or second pregnancy and in most cases, there were no hospitalizations during the pregnancy in both tested groups. Medications are more often used during the implementation of the baby friendly program. The reason for positive influence of the use of medications during the pregnancy on implementation of the baby friendly program probably lies in better supervision of the pregnancy. The gestation age did not influence the selection into the program. By means of higher level of supervision and by the use of medications during pregnancy, we can positively influence mother`s and infant`s starting with the baby friendly programme implementation.

Purpose: As Baby Boomers enter late life, relationships with family members gain importance. This review article highlights two aspects of their intergenerational relationships: (a) caregiving for aging parents and (b) interactions with adult children in the context of changing marital dynamics. Design and Methods: The researchers describe three studies: (a) the Within Family Differences Study (WFDS) of mothers aged 65–75 and their multiple grown children (primarily Baby Boomers) ongoing since 2001; (b) the Family Exchanges Study (FES) of Baby Boomers aged 42–60, their spouses, parents, and multiple grown children ongoing since 2008; and (c) the Longitudinal Study of Generations (LSoG) of 351 three-generation families started when the Baby Boomers were teenagers in 1971, with interviews every 3–5 years from 1985 to 2005. Results: These studies show that the Baby Boomers in midlife navigate complex intergenerational patterns. The WFDS finds aging parents differentiate among Baby Boomer children in midlife, favoring some more than others. The FES shows that the Baby Boomers are typically more involved with their children than with their aging parents; Boomers’ personal values, family members’ needs, and personal rewards shape decisions about support. The LSoG documents how divorce and remarriage dampen intergenerational obligations in some families. Moreover, loosening cultural norms have weakened family bonds in general. Implications: Reviews of these studies provide insights into how the Baby Boomers may negotiate caregiving for aging parents as well as the likelihood of family care they will receive when their own health declines in the future.

Death without dignity for commercial surrogacy: the case of Baby M.

Science.gov (United States)

Annas, G J

1988-01-01

The New Jersey Supreme Court's In re Baby M ruling is applauded for remedying the flawed opinion of the lower court by invalidating surrogate contracts, applying existing law to determine custody, and restoring the natural mother's parental rights. Portions of the decision highlighted are the court's rejection of the label "surrogate mother" and the claim that surrogacy promotes family building. The author analyzes the surrogacy contract's violation of existing adoption laws, the constitutional issues raised by the contract, the court's controversial ruling on custody, and responses to the opinion by commercial baby brokers. He concludes that legislation must be enacted now to prevent "full surrogacy," in which in vitro fertilization and embryo transfer render the gestational mother an incubator with no rights or interests in the child.

Food allergy is a rare disorder among breastfeeding babies. Our aim was to identify responsible allergens in human milk. We studied babies developing allergic symptoms at the time they were breastfeeding. Skin prick tests (SPT) were performed with breast milk and food allergens. Specific IgE was assessed and IgE Immunoblotting experiments with breast milk were carried out to identify food allergens. Clinical evolution was evaluated after a maternal free diet. Five babies had confirmed breast milk allergy. Peanut, white egg and/or cow's milk were demonstrated as the hidden responsible allergens. No baby returned to develop symptoms once mother started a free diet. Three of these babies showed tolerance to other food allergens identified in human milk. A maternal free diet should be recommended only if food allergy is confirmed in breastfed babies.

Few interventions for Postnatal Depression (PND) have focused on parenting difficulties; the aim of this research was to investigate the feasibility and evaluate a parenting intervention (Baby Triple P) in women with PND. This was a pilot randomised controlled trial (RCT) to evaluate and determine the feasibility of the newly developed Baby Triple P compared with treatment as usual (TAU) in women with PND. In all, 27 female participants aged from 18 to 45 years (mean age = 28.4 years, standard deviation (SD) = 6.1), with a primary diagnosis of major depression and an infant under 12 months (mean age = 6.2 months, SD = 3.2 months), were recruited from primary care trusts in Greater Manchester, United Kingdom. Participants were randomly allocated to receive either eight Baby Triple P sessions in addition to TAU or TAU only. Outcomes were assessed at post-treatment (Time 2) and 3 months post-treatment (Time 3). Self-report outcomes were as follows: Beck Depression Inventory, Oxford Happiness Inventory, What Being the Parent of a New Baby is Like, Postpartum Bonding Questionnaire and the Brief Parenting Beliefs Scale-baby version. An assessor-rated observational measure of mother-infant interaction, the CARE Index and measure of intervention acceptability were also completed. Significant improvements from Time 1 to Time 2 and Time 1 to Time 3 were observed across both groups. Although women allocated to Baby Triple P showed more favourable improvements, the between-group differences were not significant. However, the intervention was highly acceptable to women with PND. A large-scale RCT is indicated. © The Author(s) 2014.

Full Text Available Background: Fluoride has been widely used in the prevention of dental caries for a long time. To prevent dental caries, fluoride must be induced in low amount at high frequency. Inducing it through implantation process even make slow release of small concentration of fluoride. Purpose: The aim of this research was to analyze whether the induction of monofluorophosphate (MFP implant into the white rat mothers affects the level of fluoride in the incisors of their young babies. Method: The objects of the research were twenty white rat mothers in two days of pregnancy which then were divided into four groups (n=5. First, those mothers have been induced with implant under their back skin until their born young babies in the age of 35 days (n=5. The level of fluoride in the incisors of those young babies then is measured with Potentiometer. The obtained data were finally analyzed with One-Way ANOVA test and continued by with LSD test (p=0.05. Result: The result of this research showed that the means of the fluoride level in the incisors of those babies divided into those four groups in series were about 11956.16±201.35 ppb (K, 27328.04±234.56 ppb (P1, 37267.21±248.86 ppb (P2, and 18103.50±267.11 ppb (P3. The result of ANOVA test then showed that the induction of various MFP implant levels significantly affected the level of fluoride in the incisors of the babies. The mean differences among the treatment groups after being tested with LSD 0.05 were also significant. Conclusion: The finding confirm that the significant increasing of the optimal fluoride retention in the incisors of white rat babies can be achieved with the induction of fluoride with MFP ions implant in about 52.98 mg.Latar belakang: Pencegahan karies gigi menggunakan senyawa fluor telah banyak dilakukan dan berlangsung dalam jangka waktu lama.

Full Text Available This paper aims to simulate the effects of different friction models on tire braking. A truck radial tire (295/80R22.5 was modeled and the model was validated with tire deflection. An exponential decay friction model that considers the effect of sliding velocity on friction coefficients was adopted for analyzing braking performance. The result shows that the exponential decay friction model used for evaluating braking ability meets design requirements of antilock braking system (ABS. The tire-pavement contact stress characteristics at various driving conditions (static, free rolling, braking, camber, and cornering were analyzed. It is found that the change of driving conditions has direct influence on tire-pavement contact stress distribution. The results provide the guidance for tire braking performance evaluation.

1997-01-01

Cryopolymers, Inc. tapped NASA expertise to improve a process for recycling vehicle tires by converting shredded rubber into products that can be used in asphalt road beds, new tires, hoses, and other products. In conjunction with the Southern Technology Applications Center and Stennis Space Center, NASA expertise in cryogenic fuel-handling needed for launch vehicle and spacecraft operations was called upon to improve the recycling concept. Stennis advised Cryopolymers on the type of equipment required, as well as steps to reduce the amount of liquid nitrogen used in the process. They also guided the company to use more efficient ways to control system hardware. It is estimated that more than 300 million tires nationwide are produced per year. Cryopolymers expects to reach a production rate of 5,000 tires recycled per day.

The recycling of waste tires has been a big environmental problem. About 280 million waste tires are produced annually in the United States and more than 2 billion tires are stockpiled, which cause fire hazards and health issues. Tire rubbers are insoluble elastic high polymer materials. They are not biodegradable and may take hundreds of years to decompose in the natural environment. Microwave irradiation can be a thermal processing method for the decomposition of tire rubbers. In this study, the microwave absorption properties of waste tire at various temperatures are characterized to determine the conditions favorable for the microwave heating of waste tires.

Full Text Available Background: Periodontal infections, which serve as a reservoir of inflammatory mediators, may pose a threat to the fetal-placental unit and cause adverse pregnancy outcomes. Objective: The aim of this study was assessing the periodontal status of women during puerperium and determining the possible relationship between their periodontal disease and low birth weight delivery. Materials and Methods: This was a case-control study. The sample included 88 ex-pregnant women were seen at maternity hospitals of Yazd, Iran. Half of the mothers had low birth babies (LBW (birth weight below 2500g- case group and the others had normal weight babies (>2500g- control group. The mothers’ data were obtained from medical files, interview and periodontal clinical examination carried out up to 3 days after delivery. Bleeding on probing, presence of supra-gingival calculus and CPITN (Community Periodontal Index for Treatment Needs were used for periodontal assessment Results: Among the known risk factors of LBW babies, history of previous LBW infant among case mothers reached statistical significance (p=0.0081, Student t-test. Mothers of LBW infants had less healthy areas of gingiva (p=0.042, and more deep pockets (p=0.0006, Mann-Whitney test. Conclusion: The maternal periodontal disease can be a potential independent risk factor for LBW.

Breastfeeding policies and breastfeeding support programs in the mother's workplace.

Science.gov (United States)

Bettinelli, Maria Enrica

2012-10-01

Women should never be forced to make a choice between mother-work and other work. Many women mistakenly think they cannot breastfeed if they plan to return to work, and thus they may not talk with their employers about their intention to breastfeed or how breastfeeding might be supported at their workplace. All breastfeeding policies and strategies underline the importance of providing support for lactating mothers and highlight the need to promote specific interventions in the workplace. Possible strategies for working mothers include having the mother keep the baby with her while she works, allowing the mother to go to the baby to breastfeed during the workday, telecommuting, offering flexible work schedules, maintaining part-time work schedules, and using on-site or nearby child care centres.

Tire inspection machine presenting an X-ray image of the entire width of the tire

International Nuclear Information System (INIS)

1975-01-01

An X-ray machine for production line inspection of tires places each tire in turn with one sector of the tire inside of a U-shaped arrangement of three fluorescent screens so that one screen faces the tread and the other two face the sides of the tire. An X-ray source inside the bead circle of the tire produces X-ray shadow pictures on the screens, which are separately viewed by a video camera, with an image of the picture on each screen transferred to a third of the target of a storage tube, so that a composite image of the entire width of the tire sector can be displayed on a picture tube. The tire is rotated step-wise for display of still pictures of every sector of the tire. (Auth.)

Full Text Available We are reporting a rare case of severe hemolytic disease of newborn (HDN with Bombay phenotype mother. A retrospective study of a case with severe haemolytic disease of newborn with Bombay phenotype mother was done. Blood grouping, antibody screening, and lectin study was done on the blood sample of the baby and mother to confirm the diagnosis. Hematological and biochemical parameters were obtained from the hospital laboratory information system for the analysis. Blood group of the baby was A positive, direct antiglobulin test was negative. Blood group of the mother was confirmed to be Bombay phenotype, Hematological parameters showed all the signs of ongoing hemolysis and the bilirubin level was in the zone of exchange transfusion. Due to the unavailability of this rare phenotype blood unit, baby was managed conservatively. Anticipating the fetal anemia and HDN with mothers having Bombay phenotype and prior notification to the transfusion services will be of great help in optimizing the neonatal care and outcome.

de Groot, Sonja; Vegter, Riemer J K; van der Woude, Lucas H V

2013-10-01

The purpose of this study was to evaluate the effect of wheelchair mass, solid vs. pneumatic tires and tire pressure on physical strain and wheelchair propulsion technique. 11 Able-bodied participants performed 14 submaximal exercise blocks on a treadmill with a fixed speed (1.11 m/s) within 3 weeks to determine the effect of tire pressure (100%, 75%, 50%, 25% of the recommended value), wheelchair mass (0 kg, 5 kg, or 10 kg extra) and tire type (pneumatic vs. solid). All test conditions (except pneumatic vs. solid) were performed with and without instrumented measurement wheels. Outcome measures were power output (PO), physical strain (heart rate (HR), oxygen uptake (VO2), gross mechanical efficiency (ME)) and propulsion technique (timing, force application). At 25% tire pressure PO and subsequently VO2 were higher compared to 100% tire pressure. Furthermore, a higher tire pressure led to a longer cycle time and contact angle and subsequently lower push frequency. Extra mass did not lead to an increase in PO, physical strain or propulsion technique. Solid tires led to a higher PO and physical strain. The solid tire effect was amplified by increased mass (tire × mass interaction). In contrast to extra mass, tire pressure and tire type have an effect on PO, physical strain or propulsion technique of steady-state wheelchair propulsion. As expected, it is important to optimize tire pressure and tire type. Copyright © 2013 IPEM. Published by Elsevier Ltd. All rights reserved.

Analysis of automotive tire construction. Jidosha tire no kozo kaiseki

Energy Technology Data Exchange (ETDEWEB)

Ishihara, K. (Toyo Tire and Rubber Co. Ltd., Osaka (Japan))

1993-06-15

This paper introduces features and trends of analyzing performance and construction of automotive tires. Tires are demanded of high durability, high motion performance, good comfort performance for vibration and noise, and low fuel consumption performance. A feature of analyzing the construction is to execute a modelling assuming that a tire has air-rigid flexible structure and rubber materials show hyperelastic behavior, hypothesizing a strain energy density function. In addition, a tire is highly incompressible. Visco elasticity and anti-friction performance are also important points. Rubber and cord layers have elastic characteristic of three-dimensional perpendicular anisotropy as well as non-linearity with which characteristics change according to transformation. A structural analysis must cover from static analysis to steady dynamic analysis, non-steady dynamic analysis, and eigenvalue analysis. Thermal analysis of tires simulates phenomena by combining dynamical analysis with thermal analysis. Super-computers have now come to be used for formulating equilibrium equations using finite element methods, developing finite elements, and performing heat or visco elasticity analysis and applied analysis. 35 refs., 3 figs.

2000-11-01

Various methods for measuring the milk intake of breast fed babies are available. Most methods are time consuming, cumbersome and inaccurate. The report describes various methods used for Breast Milk intake measurement with emphasis on the D/sub 2/O dilution method. The methodology of the D/sub 2/O dilution method is now streamlined in this Inst. for measuring the milk intake of babies. Advantages and disadvantages of all the methods used to determine the breast milk intake of the infants are also included in the present report. For the D/sub 2/O dilution method, and oral administration of small dose of deuterium oxide (sup 2/H/sup 2/O) is given to the mothers after collecting pre-dose samples. The post dose samples of urine from the baby and saliva from the mother are collected at 24 hours intervals over a 14 days period. These samples are analyzed on isotope ratio Mass spectrometer. The D/H values obtained over a 14 days period are then extrapolated to calculate the milk intake of babies using the Microsoft Excel Computer programme designed for this purpose. (author)

Patricia Alvarenga

2013-09-01

Full Text Available This longitudinal study investigated the impact of maternal mental health, including postpartum depression, and of maternal-fetal attachment, on maternal sensitivity when babies were eight months old. The study included 38 mother-infant dyads. The women answered the SRQ-20 and the Maternal-Fetal Attachment Scale in the third trimester of pregnancy, and the BDI, for evaluation of postpartum depression in the first month following birth. Maternal sensitivity was examined through an observation of mother-child interaction when babies were eight months old. The multiple regression model considering the three factors explained 18.6% of the variance in sensitivity, and only maternal-fetal attachment was a significant predictor. The results indicate the importance of interventions to promote the bond of pregnant women with their babies, which may even minimize possible harmful effects of postpartum depression on mother-child interaction.

Making time for well-baby care: the role of maternal employment.

Science.gov (United States)

Hamman, Mary Kathryn

2011-10-01

The American Academy of Pediatrics recommends children receive six well-baby visits between ages 1 month and 1 year, yet by age 14 months less than 10% of infants have received all six visits. Cost sharing under public and private insurance is very low. Low compliance rates despite the low cost of care suggest other factors, such as time costs, may be important. This paper examines the relationship between maternal employment and receipt of well-baby care. The Medical Expenditure Panel Survey contains rich information on use of preventive care, maternal employment, and other economic and non-economic factors that may influence care decisions. Several approaches, including a proxy variable strategy and instrumental variables analysis, are used to attempt to address the potential endogeneity of maternal employment and examine the sensitivity of findings. Findings indicate mothers who work full-time take their children to 0.18 fewer visits (or 9% fewer at the mean) than those who have quit their jobs. Mothers with employer provided paid vacation leave take their children to 0.20 more visits (or 9% more at the mean) than other working mothers. Time appears to be an important factor in determining well-baby care receipt. Policies that extend paid leave to more employed women may improve compliance with preventive care recommendations.

1988-01-01

We compared results of urine drug analysis with clinical data and history to test the usefulness of peripartum drug screening and to establish guidelines for optimal testing. Urine from 28 mothers and 52 babies was analysed. Drugs not suspected by history were found in 10 mothers and six babies. Results assisted in the management of neonatal withdrawal in three babies. Drugs suspected by history were not found in 11/22 mothers and 23/35 babies. About half of these results were associated with delayed urine collection. In 12/28 mothers, drugs administered in hospital could have confused interpretation of screen results. We conclude that urine drug screening without strict protocols for specimen collection is of limited usefulness for management of drug abuse in pregnancy and neonatal drug withdrawal. We favour testing of maternal urine obtained before drugs are administered in hospital. Neonatal urine, if used, should be collected in the first day of life.

Feeding by numbers: an ethnographic study of how breastfeeding women understand their babies' weight charts

Directory of Open Access Journals (Sweden)

Dykes Fiona

2006-12-01

Full Text Available Abstract Background Weighing breastfed babies has been the subject of some controversy as the previous international growth chart was largely based on data from infants fed infant formula. The concern that professionals may be misled by the charts into suggesting to mothers that they supplement unnecessarily was a major impetus for the World Health Organization's investment in a new growth chart. Evidence of interpretation in practice has been scant. Methods An ethnographic study was conducted in a town in the Northwest of England to investigate this issue. In the first phase, women and health visitors were observed in the well-child clinic during clinic sessions and breastfeeding group meetings. In the second phase, longitudinal interviews with 14 women were conducted. Each woman was interviewed up to three times in the first six months after the birth of her baby, with a total of 35 interviews. Results Mothers and health visitors focussed on weight gain with frequent weighing and attention to even minor fluctuations of the plotted line being evident. Women felt it important to ensure their baby's weight followed a centile, and preferred for this to be the fiftieth centile. Interventions included giving infant formula and solids as well as changing what the mother ate and drank. Women also described how they worried about their baby's weight. Little effective support by health professionals with breastfeeding technique was observed. Conclusion Babies were weighed more often than officially recommended, with weighing and plotting being at the core of each clinic visit. The plotted weight chart exerted a powerful influence on both women's and health visitors' understanding of the adequacy of breastfeeding. They appeared to rate the regular progression of weight gains along the chart centiles more highly than continued or exclusive breastfeeding. Thus weighing and visual charting of weight constituted a form of surveillance under the medical gaze

Method and apparatus for inspecting tires

International Nuclear Information System (INIS)

Fox, R.L.T.

1975-01-01

A method and apparatus for inspecting tires by the use of x-rays is disclosed in which a tire is advanced to an inspection station, engaged along opposite bead rims and inflated to axially spread the bead rims and side walls. An x-ray source is advanced axially into the tire and the tire is eccentrically rotated relative to the x-ray source to enable radial positioning of the source relative to the tire near the tire bead rim diameter without requiring radial movement of the x-ray source. The x-ray source produces an x-ray beam which sweeps about the interior of the expanded tire from bead rim to bead rim while the tire is rotated about its centerline. An x-ray detection system detects x-rays which have penetrated the wall and produces inspection information concerning the tire construction. (Patent Office Record)

Although racial/ethnic disparities in neonatal and infant health are well known, positive associations between migration and perinatal health exist among immigrant mothers in western countries. There are unique marriage migration, East Asia culture, universal national health insurance system, and adequate social support in Taiwan that may differ from the situation in western countries. We aimed to assess the neonatal outcomes among live births to married immigrant mothers in recent years in Taiwan. We conducted a population-based analysis among all the live births in Taiwan during the period 1998-2003 to assess neonatal outcomes, including incidence of low birth weight and preterm birth and of early and late neonatal mortality, according to maternal nationality. Logistic regression was used to estimate the odds ratios (ORs) associated with low birth weight and preterm birth, and Cox proportional hazards were used to estimate the relative risks (RRs) associated with mortality in the neonatal period. There were a total of 1,405,931 single live births, including 6.6% born to immigrant mothers and 93.4% born to Taiwanese mothers. Disparities existed among the intercultural couples, including paternal age, parental educational level, and residential distribution. Fewer low birth weight and fewer preterm babies were born to immigrant mothers than to Taiwanese mothers. In addition, babies born to immigrant mothers had lower early neonatal and neonatal mortalities than those born to Taiwanese mothers. There were lower risks of having a low birth weight (adjusted OR [AOR] 0.73, 95% confidence interval [CI] 0.70-0.75) or preterm (AOR 0.72, 95% CI 0.69-0.74) baby and lower hazard ratios (HRs) of having an early neonatal death (adjusted HR [AHR] 0.68, 95% CI 0.56-0.82) or neonatal death (AHR 0.74, 95% CI 0.64-0.87) in babies born to immigrant mothers. There is a gradual increase in the risks of adverse neonatal outcomes associated with increases in length of residence

2011-11-01

To provide an understanding of Chinese new mothers' breastfeeding behaviors and especially to explore the relationship between the mothers perceived family perception about breastfeeding and the new mothers' breastfeeding behaviors. A cross-sectional questionnaire survey was conducted in Beijing and Yinchuan, the capital of Ning Xia Province, China. 214 new mothers with a baby at the age of 4 months were recruited to the study. The family perception of breastfeeding scale and the new mothers' breastfeeding behavior record were used. The response rate was n=200, 94%. Most of the new mothers perceived positive family perceptions about breastfeeding with an average score of 23.13 using the family perception of breastfeeding scale. Nearly half of the respondents reported that they exclusively breastfed their infants (n=94, 47%). The main reason for breastfeeding difficulty was inadequate lactation (n=56, 69%). The new mothers who breastfed their infants mentioned significantly stronger family perceptions/support compared to those who used mixed feeding or artificial feeding (p0.05) in the types of mothers' feeding behaviors across the different age group, occupation, ethnicity, educational level, mode of delivery, the time of the baby's first suck, bottle feeding before the baby's first suck and the time of having colostrums. It is suggested to develop some strategies, such as family-centered antenatal and postnatal education programmes, to increase the rate of exclusive breastfeeding by influencing new mothers' families about breastfeeding. Further research is needed to explore socio-demographic variables associated with new-mothers' breastfeeding behaviors. Copyright © 2011 Elsevier B.V. All rights reserved.

Impact of forced separation policy on incarcerated postpartum mothers.

Chambers, Angelina N

2009-08-01

The number of incarcerated women in the United States is steadily increasing with 9% giving birth while serving time. Mothers and babies are routinely separated immediately and during most of the postpartum period. This qualitative study examines the impact of this policy by exploring the nature and meaning of the mother-infant bonding experience when the mothers know separation is coming. Twelve incarcerated postpartum mothers were interviewed during the early postpartum period about their antepartum and postpartum relationships with their babies. Qualitative data analysis produced four relational themes: (a) "a love connection," (b) "everything was great until I birthed," (c) "feeling empty and missing a part of me," and (d) "I don't try to think too far in advance." Results of this qualitative study provide information to professionals exploring gender-sensitive prison policies for the growing female population.

Tire-soil interaction model for turning (steered) tires

Karafiath, L. L.

1985-07-01

A review of the experimental information on the development of lateral forces on tires traveling at an angle to their center plane is presented and the usefulness of the consideration of the lateral forces for the development of an analytical model is evaluated. Major components of the lateral force have been identified as the forces required to balance the tractive force and the drawbar pull vectorially. These are the shear stresses developing in the contact area and the horizontal component of the normal stresses acting on the in-ground portion or the curved side walls of the tire. The tire-soil interaction model for steady state straight travel has been expanded to include the necessary algorithms for the calculation of these lateral forces. The pattern of tractive force-slip and longitudinal-lateral force relationships is in general agreement with experiments.

Zinc Leaching from Tire Crumb Rubber

Science.gov (United States)

Rhodes, E. P.; Ren, J.; Mays, D. C.

2010-12-01

Recent estimates indicate that more than 2 billion scrap tires are currently stockpiled in the United States and approximately 280 million more tires are added annually. Various engineering applications utilize recycled tires in the form of shredded tire crumb rubber. However, the use of tire crumb rubber may have negative environmental impacts, especially when the rubber comes into contact with water. A review of the literature indicates that leaching of zinc from tire crumb rubber is the most significant water quality concern associated with using this material. Zinc is generally used in tire manufacturing, representing approximately 1.3% of the final product by mass. This study will report results from the U.S. Environmental Protection Agency’s (EPA’s) Synthetic Precipitation Leaching Procedure, batch leaching tests, and column leaching tests performed to quantify the process by which zinc leaches from tire crumb rubber into water. Results are interpreted with a first-order kinetic attachment/detachment model, implemented with the U.S. Agricultural Research Service software HYDRUS-1D, in order to determine the circumstances when zinc leaching from tire crumb rubber would be expected to comply with the applicable discharge limits. One potential application for recycled tires is replacing sand with tire crumb rubber in granular media filters used for stormwater pollution control. For this to be a viable application, the total zinc in the stormwater discharge must be below the EPA’s benchmark value of 0.117 mg/L.

Abortion denied--outcome of mothers and babies.

Science.gov (United States)

Del Campo, C

1984-02-15

A consistent argument favoring therapeutic abortions has been that mothers who are denied abortions will seek "illegal" help elsewhere, often in less than optimal conditions. Yet, a review of published reports on women who had been denied abortion and were followed up shows that 70.67% of the 6298 women completed their pregnancies and only 13.2% had an abortion elsewhere. Several studies have shown that the incidence of Complications of pregnancy is no greater in mothers denied abortion than in paired controls. The results of a prospective study by Laukaran and Van Den Berg showed a higher incidence of maternal accidental injury, a borderline increase of maternal accidental injury, a borderline increase in the prevalence of congenital anomalies, and a higher incidence of infection and hemorrhage during the puerperium in women who had been denied abortion. They concluded that maternal attitude and psychosocial stress had little effect on the progress of the pregnancy and labor. Published reports on the psychological effects on the children of women who had been denied abortion are few, mainly because longterm follow-up is required. In 1966 Forssman and Thuwe described the results of their study of 120 children whose mothers had been denied abortion. The children had been followed up until their 21st birthdays. The controls had been carefully paired. The proportion of children who had been placed in foster and children's homes was significantly higher among the "unwanted" children than among the controls (50% versus 18%). There was no statistically significant difference in the rates of drunken misconduct, crime, or "educational mental subnormality" between the 2 groups, but the incidence rates of delinquency and psychiatric consultation were 10% and 13% higher respectively among the unwanted children than among the controls. There have been virtually no objective studies on the psychologic and social well-being of women who have been denied abortion. The literature

This paper aims to simulate the effects of different friction models on tire braking. A truck radial tire (295/80R22.5) was modeled and the model was validated with tire deflection. An exponential decay friction model that considers the effect of sliding velocity on friction coefficients was adopted for analyzing braking performance. The result shows that the exponential decay friction model used for evaluating braking ability meets design requirements of antilock braking system (ABS). The ti...

Cocaine use and the breastfeeding mother.

Science.gov (United States)

Jones, Wendy

2015-01-01

Cocaine is the second most commonly used illicit drug. Use in pregnancy and breastfeeding may have severe consequences for the baby due to its pharmacokinetic properties. Midwives need to be aware of the prolonged action of cocaine and be alert to the possibility of cocaine toxicity if a baby is excessively irritable and tachycardic. Euphoric highs are brief but breast milk and urine remain positive for long periods. Infant urine following exposure to cocaine via breast milk may remain positive for up to 60 hours. Mothers who snort cocaine should pump and dump breast milk for 24-48 hours. Passive inhalation of crack cocaine smoke may also result in infants with positive toxicology screens. Cocaine powder should never be applied to the nipples of breastfeeding mothers.

Mother's perceptions of postpartum stress and satisfaction.

Horowitz, J A; Damato, E G

1999-01-01

To examine mothers' postpartum perceptions of stress and satisfaction. Methodologic triangulation with quantitative and qualitative data in a nonexperimental design. A convenience sample of 95 women was obtained during normally scheduled postpartum appointments at a health maintenance organization. The self-administered questionnaire included the Mothers' Information Tool (MIT), What Being the Parent of a Baby Is Like (WPL-R), and the Brief Symptom Inventory (BSI). Open-ended MIT items revealed mothers' perceptions of stress and satisfaction. The WPL-R provided maternal satisfaction scores, and the BSI yielded Global Stress Index scores. Content analysis identified the following categories: Roles, Tasks, Resources, and Relationships. Subcategories identified as areas of stress were Work/School, Sleep/Rest, Adjustment/Own Needs, Health/Body Image, Organization of Life, Child Care, Day Care, Housework, Future Challenges, Finances, Housing, Time, Partner, and Family. Subcategories identified as areas of satisfaction were Participating in Relationships, Sharing the Future, Being Proud to Be a Mother, Enjoying a Healthy Baby, and Caring for a Child. Levels of stress and satisfaction of mothers who scored high and low on quantitative measures were compared. The outcomes contribute to the knowledge concerning postpartum women's perceptions of the mothering experience and suggest approaches to nursing assessment and intervention to prevent postpartum adjustment difficulties.

Original article The effects of kangaroo mother care in a sample of preterm, preschool aged children

Full Text Available Background The research has shown that kangaroo mother care has a protective impact both on health and future cognitive skills of prematurely born babies. The aim of this study was to investigate the relation between the early skin-to-skin contact and the cognitive and emotional-social functioning of preschool aged preterm babies. Participants and procedure The study group included 99 preterm babies. The children participated in a psychological examination conducted using the Columbia Mental Maturity Scale and the Terman-Merrill Test. The data concerning the skin-to-skin contact during the child’s hospitalisation were acquired during interviews with mothers. The emotional development was assessed on the basis of interviews with mothers, conducted using the Rescorla DSM-IV Orientation Scale (2005. Results The study showed no relation between kangaroo mother care and cognitive development. Nevertheless the early skin-to-skin contact turned out to be connected with the emotional functioning of the subjects. Preterm babies who used to experience kangaroo mother care experienced fewer anxiety and depressive disorders than those who did not. In addition it was revealed that the children who suffered from early damage to the brain in the forms of intraventricular and periventricular haemorrhages and experienced kangaroo mother care demonstrated less intense depressive symptoms than those who did not. Conclusions The obtained results, combined with the review of the foreign literature of the subject, indicate the usefulness of introducing kangaroo mother care to neonatal wards and encouraging parents to care about their prematurely born babies in such a way.

Full Text Available Objective: To identify the relationship between periodontitis in pregnant women through the periodontal disease index (PDI and low birth weight babies. Methods: A case-control study was conducted to determine the relationship between periodontitis in pregnant women through the periodontal disease index (PDI and the low birth weight babies (LBW. The participants were mothers with periodontitis and non-periodontitis mothers aged 20–35 years who gave birth in the Department of Obstetrics and Gynecology-Dr. Hasan Sadikin General Hospital, Bandung in the period of December to January 2005. Results: Based on the chisquare test results a highly significant relationship between periodontitis and low birth weight (p=0.002 was found. The Odd’s ratio showed that the risk of low birth weight in pregnant women with periodontitis was 15.58 times higher compared to those who did not suffer from periodontitis. The periodontal disease index has an accuracy of 88.6% in predicting the incidence of LBW. It strongly influenced the incidence of LBW with a high Odd’s ratio of 28.0. Pregnant women who suffer from periodontitis with a PDI > 3.25, have 19.2 times higher risk for delivering babies with LBW compared to the non-periodontitis mothers. Conclusions: The loss of attachment affects the possibility of delivering LBW babies.

Baby Factories in Nigeria: Starting the Discussion Toward a National Prevention Policy.

Baby factories and baby harvesting are relatively new terms that involve breeding, trafficking, and abuse of infants and their biological mothers. Since it was first described in a United Nations Educational, Scientific and Cultural Organization report in Nigeria in 2006, several more baby factories have been discovered over the years. Infertile women are noted to be major patrons of these baby factories due to the stigmatization of childless couples in Southern Nigeria and issues around cultural acceptability of surrogacy and adoption. These practices have contributed to the growth in the industry which results in physical, psychological, and sexual violence to the victims. Tackling baby factories will involve a multifaceted approach that includes advocacy and enacting of legislation barring baby factories and infant trafficking and harsh consequences for their patrons. Also, programs to educate young girls on preventing unwanted pregnancies are needed. Methods of improving awareness and acceptability of adoption and surrogacy and reducing the administrative and legal bottlenecks associated with these options for infertile couples should be explored to diminish the importance of baby factories. © The Author(s) 2015.

Azam Nickkhaha

2015-06-01

Full Text Available Background: The Baby-Friendly Hospital Initiative was launched in 1989 by World Health Organization and the United Nations Children's Fund for the promotion of breastfeeding. This program was implemented in many departments of gynecology and obstetrics and resulted in reduced malnutrition, infection, morbidity and mortality in children. This program has introduced 10 specific steps to support successful breastfeeding. For instance, in the fourth step, skin-to-skin contact and breastfeeding are promoted since the time of birth, and in the fifth step, mothers are instructed on how to breastfeed or persist in breastfeeding. In these ten steps, mothers are trained in various fields. Methods: In this cross-sectional study, a standardized questionnaire was used to collect data at baby-friendly hospitals. To assess the difference between multiple nominal variables, variance analysis was performed, using SPSS version 17. Results: Based on the analysis, mothers' awareness of the benefits of breast milk and breastfeeding was 83% in a baby-friendly hospital. Also, their awareness of proper breastfeeding was estimated at 78.5%. In addition, mothers' knowledge about the frequency of breastfeeding was 70%. Conclusion: Given the role of Baby-Friendly Hospital Initiative in training mothers on the importance of breastfeeding and its persistence in future, careful monitoring of these hospitals, breastfeeding support services and breastfeeding training by midwives at healthcare centers are of great importance.

Evans, J J

1997-01-01

Tires have a deleterious effect on the environment. This review discusses the background of scrap tires discarded in the environment, including tire composition, adverse environmental effects, threats to public health and safety, and solid waste management. Despite the widespread use of scrap tires in environmental applications, both land-based and aquatic, data on the indicators of environmental degradation are extremely scarce. Indicators of environmental degradation include analysis of chemicals within the water and sediment, analysis of contaminants within organisms, and analysis of the biological effects of these compounds on plants, animals, microbes, and organelles. Although these indicators are most useful when used in parallel, a review of the available information on chemical characterization of tire leachate from tire storage facilities, manufacturing, usage in recycling applications, and toxicity exposure studies, of vegetation surveys from waste tire areas and reviews of mammalian tire product toxicity, and of toxicity, mutagenicity, and carcinogenicity of tire exposure in experimental aquatic animals, microbes, and organelles is presented. The major characteristics of these studies are discussed in specific sections. The "Discussion and Conclusions" section discusses and summarizes the biological effects and chemical characterization of tire leachates. A global environmental perspective is included to improve our understanding of the deficiency of the current knowledge of tire leachate toxicity from various sources and to encourage interdisciplinary studies to establish the pattern of pollution associated with waste tire management.

to describe the grief of mothers and fathers and its influence on their relationships after the loss of a stillborn baby. a postal questionnaire at three months, one year and two years after stillbirth. a study of mothers and fathers of babies stillborn during a one-year period in the Stockholm region of Sweden. 55 parents, 33 mothers and 22 fathers. mothers and fathers stated that they became closer after the loss, and that the feeling deepened over the course of the following year. The parents said that they began grieving immediately as a gradual process, both as individuals, and together as a couple. During this grieving process their expectations, expressions and personal and joint needs might have threatened their relationship as a couple, in that they individually felt alone at this time of withdrawal. While some mothers and fathers had similar grieving styles, the intensity and expression of grief varied, and the effects were profound and unique for each individual. experiences following a loss are complex, with each partner attempting to come to terms with the loss and the resultant effect on the relationship with their partner. anticipating and being able to acknowledge the different aspects of grief will enable professionals to implement more effective intervention in helping couples grieve both individually and together.

2016-01-01

Full Text Available Background: Kangaroo Mother Care (KMC is dened as skin-to-skin contact between a mother and her newborn baby derived from practical similarities to marsupial care giving, proximately exclusive breastfeeding and early discharge from hospital. This concept was proposed as an alternative to conventional methods of care for low birth weight (LBW infants, and in replication to quandaries of earnest overcrowding in Neonatal Intensive Care Units (NICUs. KMC essentially utilizes the mother as a natural incubator Aim and Objectives: The aim was to assess the feasibility, acceptability and the effectiveness of KMC in LBW infants. It avoids agitation routinely experienced in busy ward. Material and Methods: A pilot open-labeled quasi-randomised clinical trial was conducted in Level III NICU of a teaching institution. 60 newborn infants <2500 g, meeting inclusion criteria were alternatively randomised into two groups: Kangaroo Mother Care (KMC and Conventional Methods of Care (CMC. Kangaroo mother care was practiced with minimum total period of eight hours a day intermittently for the intervention group while the controls remained in incubators or cots. Weight, head circumference, length, morbidity episodes, hospital stay, feeding patterns were monitored for all infants till postmenstrual age of 42 weeks in preterm babies or till a weight of 2500 g is achieved in term SGA babies. Results: The pilot study conrmed that trial processes were efcient, the intervention was acceptable (to mothers and nurses and that the outcome measures were appropriate; KMC babies achieved signicantly better growth at the end of the study (For preterm babies, weight, length and head circumference gain were signicantly higher in the KMC group (weight 19.28±2.9g/day, length 0.99±0.56cm/week and head circumference 0.72±0.07 cm/week than in the CMC group (P <0.001.

2016-07-01

Full Text Available Introduction: Sounds are part of our life and are able to produce effects on physical and emotional balance of people. Objective: To evaluate the effects of mother’s singing on the preemie using as parameters the heart and respiratory frequency and blood oxygen concentration of preemies, and also the mother perception related to baby behavior during the exposition to her singing. Methods: It is an exploratory investigation with quantitative and qualitative analyzes. Twenty preemies babies were observed during three consecutive days. Each child was exposed to the mother singing during ten minutes for three periods. The data were collected before and immediately after the music exposition. The heart and respiratory frequency and blood oxygen concentration of the baby were registered in two moments: pre and post- music exposition; the two measures were analyzed and compared. In the third day, the mother was interviewed to know her perception related to baby behavior during the singing exposition. The assessment of data was performed from March to July 2015 in two public hospitals in Sorocaba, São Paulo, Brazil. For the statistical analysis, Wilcoxon, Mc Nemar and variance test of Friedman were applied. Results and Conclusion: Statistics showed no significant results, however the qualitative analyzes showed positive results from the mother’s speech, such as benefic changes on babies behavior, recognition of mother’s voice and in helping to consolidate the bond between mother and her baby. s positivos nos discursos obtidos das mães, tais como alterações comportamentais benéficas, reconhecimento da voz materna e auxílio na consolidação do vínculo mãe-bebê.

Describing the efficacy and achievements of the kangaroo mothers' programme (KMP) regarding preterm or low-birth-weight babies' health and development in Hospital San Rafael in Tunja from November 2007 to December 2009. This was a retrospective observational cohort study; 374 infants born prematurely or having low-birth-weight were included to assess household socio-demographic factors, maternal and obstetric history, delivery characteristics and complications and follow-up until 40 weeks post-conception age. There was a high prevalence of teenage pregnancy (17.5 %) and in women older than 35 years (12.6 %), unwanted pregnancy (40.6 %), low quality and poor availability of food in families, complications such as preeclampsia, infection and premature rupture of membranes, 1,969 grams average birth weight, 2,742.9 grams average weight on discharge and 22 grams average weight gain per day. It was found that KMP methodology substantially improved the mothers' psychological aspects and health status and the newborns' prognosis and led to stabilising body temperature and weight gain rate while decreasing risks of complications and nosocomial infection. It also lowered health care costs and shortened hospital stay.

Tire Development for Effective Transportation and Utilization of Used Tires, CRADA 01-N044, Final Report

Energy Technology Data Exchange (ETDEWEB)

Scrap tires represent a significant disposal and recycling challenge for the United States. Over 280 million tires are generated on an annual basis, and several states have large stockpiles or abandoned tire piles that are slated for remediation. While most states have programs to address the accumulation and generation of scrap tires, most of these states struggle with creating and sustaining recycling or beneficial end use markets. One of the major issues with market development has been the costs associated with transporting and processing the tires into material for recycling or disposal. According to a report by the Rubber Manufactures Association tire-derived fuel (TDF) represents the largest market for scrap tires, and approximately 115 million tires were consumed in 2001 as TDF (U.S. Scrap Tire Markets, 2001, December 2002, www.rma.org/scraptires). This market is supported primarily by cement kilns, followed by various industries including companies that operate utility and industrial boilers. However the use of TDF has not increased and the amount of TDF used by boiler operators has declined. The work completed through this cooperative research and development agreement (CRADA) has shown the potential of a mobile tire shredding unit to economically produce TDF and to provide an alterative low cost fuel to suitable coal-fired power systems. This novel system addresses the economic barriers by processing the tires at the retailer, thereby eliminating the costs associated with hauling whole tires. The equipment incorporated into the design allow for small 1-inch chunks of TDF to be produced in a timely fashion. The TDF can then be co-fired with coal in suitable combustion systems, such as a fluidized bed. Proper use of TDF has been shown to boost efficiency and reduce emissions from power generation systems, which is beneficial to coal utilization in existing power plants. Since the original scope of work outlined in the CRADA could not be completed because

Intelligent tires for identifying coefficient of friction of tire/road contact surfaces using three-axis accelerometer

International Nuclear Information System (INIS)

Matsuzaki, Ryosuke; Kamai, Kazuto; Seki, Ryosuke

2015-01-01

Intelligent tires equipped with sensors as well as the monitoring of the tire/road contact conditions are in demand for improving vehicle control and safety. With the aim of identifying the coefficient of friction of tire/road contact surfaces during driving, including during cornering, we develop an identification scheme for the coefficient of friction that involves estimation of the slip angle and applied force by using a single lightweight three-axis accelerometer attached on the inner surface of the tire. To validate the developed scheme, we conduct tire-rolling tests using an accelerometer-equipped tire with various slip angles on various types of road surfaces, including dry and wet surfaces. The results of these tests confirm that the estimated slip angle and applied force are reasonable. Furthermore, the identified coefficient of friction by the developed scheme agreed with that measured by standardized tests. (paper)

A review of the tire research programs which address the various needs identified by landing gear designers and airplane users is presented. The experimental programs are designed to increase tire tread lifetimes, relate static and dynamic tire properties, establish the tire hydroplaning spin up speed, study gear response to tire failures, and define tire temperature profiles during taxi, braking, and cornering operations. The analytical programs are aimed at providing insights into the mechanisms of heat generation in rolling tires and developing the tools necessary to streamline the tire design process and to aid in the analysis of landing gear problems.

Factors affecting exclusive breastfeeding of healthy babies aged zero to four months: a community-based study of Turkish women.

Karaçam, Zekiye

2008-02-01

The purpose of this study was to determine the factors that affect exclusive breastfeeding of healthy babies aged 0-4 months. Both the World Health Organization (WHO) and UNICEF recommend feeding babies of 0-6 months exclusively with breast milk and starting complementary foods after the sixth month. In Turkey, however, a vast majority of babies 1-5 months of age (89.4%) are given complementary foods. This cross-sectional study was conducted in central Ankara province, with a sampling of 514 individuals who were selected using the convenience sampling method. Of the 514 mothers who participated in my research, 260 (50.6%) were found to be feeding their babies exclusively with breast milk; 77 (15.0%), with breast milk + water; 87 (16.9%), with breast milk + baby formula; 70 (13.6%), with breast milk + baby formula + other foods; and 20 (3.9%), baby formula + other foods. Based on multivariate logistic regression analysis results, the mother's employment [odds ratio (OR) = 0.488; 95% confidence interval (CI) = 0.288-0.827) considerably reduced the incidence of complementary foods, while frequent crying of the baby (OR = 1.687; 95% CI = 1.125-2.530) significantly increased the use of supplementary foods in infant nutrition. This study concluded that frequent crying of the baby increases the likelihood of giving the baby complementary foods. Midwives and nurses can encourage exclusive breastfeeding behaviour by providing individual education and counselling to women whose babies cry frequently. Exclusive breastfeeding of babies aged 0-6 months is crucial for the development and growth of the baby and instrumental in reducing infant morbidities and mortalities. One factor that increases the likelihood of provision of complementary foods is frequent crying of the baby. Midwives and nurses can encourage exclusive breastfeeding behaviour by providing individual education and counselling to women whose babies cry frequently.

Full Text Available Abstract Background Early diagnosis of HIV in infants provides a critical opportunity to strengthen follow-up of HIV-exposed children and assure early access to antiretroviral (ARV treatment for infected children. This study describes findings from an Early Infant Diagnosis (EID program and the effectiveness of a prevention of mother-to-child transmission (PMTCT intervention in six health facilities in Cross-River and Akwa-Ibom states, south-south Nigeria. Methods This was a retrospective study. Records of 702 perinatally exposed babies aged six weeks to 18 months who had a DNA PCR test between November 2007 and July 2009 were reviewed. Details of the ARV regimen received to prevent mother-to-child transmission (MTCT, breastfeeding choices, HIV test results, turn around time (TAT for results and post test ART enrolment status of the babies were analysed. Results Two-thirds of mother-baby pairs received ARVs and 560 (80% babies had ever been breastfed. Transmission rates for mother-baby pairs who received ARVs for PMTCT was 4.8% (CI 1.3, 8.3 at zero to six weeks of age compared to 19.5% (CI 3.0, 35.5 when neither baby nor mother received an intervention. Regardless of intervention, the transmission rates for babies aged six weeks to six months who had mixed feeding was 25.6% (CI 29.5, 47.1 whereas the transmission rates for those who were exclusively breastfed was 11.8% (CI 5.4, 18.1. Vertical transmission of HIV was eight times (AOR 7.8, CI: 4.52-13.19 more likely in the sub-group of mother-baby pairs who did not receive ARVS compared with mother-baby pairs that did receive ARVs. The median TAT for test results was 47 days (IQR: 35-58. A follow-up of 125 HIV positive babies found that 31 (25% were enrolled into a paediatric ART program, nine (7% were known to have died before the return of their DNA PCR results, and 85 (67% could not be traced and were presumed to be lost-to-follow-up.

Processing Satellite Imagery To Detect Waste Tire Piles

Skiles, Joseph; Schmidt, Cynthia; Wuinlan, Becky; Huybrechts, Catherine

2007-01-01

A methodology for processing commercially available satellite spectral imagery has been developed to enable identification and mapping of waste tire piles in California. The California Integrated Waste Management Board initiated the project and provided funding for the method s development. The methodology includes the use of a combination of previously commercially available image-processing and georeferencing software used to develop a model that specifically distinguishes between tire piles and other objects. The methodology reduces the time that must be spent to initially survey a region for tire sites, thereby increasing inspectors and managers time available for remediation of the sites. Remediation is needed because millions of used tires are discarded every year, waste tire piles pose fire hazards, and mosquitoes often breed in water trapped in tires. It should be possible to adapt the methodology to regions outside California by modifying some of the algorithms implemented in the software to account for geographic differences in spectral characteristics associated with terrain and climate. The task of identifying tire piles in satellite imagery is uniquely challenging because of their low reflectance levels: Tires tend to be spectrally confused with shadows and deep water, both of which reflect little light to satellite-borne imaging systems. In this methodology, the challenge is met, in part, by use of software that implements the Tire Identification from Reflectance (TIRe) model. The development of the TIRe model included incorporation of lessons learned in previous research on the detection and mapping of tire piles by use of manual/ visual and/or computational analysis of aerial and satellite imagery. The TIRe model is a computational model for identifying tire piles and discriminating between tire piles and other objects. The input to the TIRe model is the georeferenced but otherwise raw satellite spectral images of a geographic region to be surveyed

To explore the impact of pre-pregnancy body mass index on baby's physical growth and nutritional status. A total of 491 pairs of mother-infant were divided into 3 groups according to mother's pre-pregnancy body mass index (BMI): a pre-pregnancy low BMI group (BMIpregnancy normal BMI group (18.5 kg/m² ≤ BMIpregnancy high BMI group (BMI ≥ 24.0 kg/m², n=72). Analysis of variance of repeated measurement data and the median percentage methods were used to compare the physical growth and nutritional status of babies in different groups. Baby's weight in the high BMI group were higher than that in the normal BMI and the low BMI group (F=3.958, P=0.020). The incidence of malnutrition in the low BMI group showed a tendency to decline along with the months (χ²=5.611, P=0.018), the incidence of overweight and obesity in the high and the normal BMI groups displayed a tendency to decline along with the months (χ²=18.773, 53.248, all PPregnancy BMI was correlated with the growth of baby. Too high or too low prepregnancy BMI exerts harmful effect on baby's weight and nutritional status. Medical workers should strengthen the education on women's pre-pregnancy to remind them keeping BMI at normal level.

To explore the meaning of rituals that women and their families perform after a stillbirth. A cultural taboo in Taiwan prohibits discussing death; thus, parents of stillborn babies have no established public mourning or burial ceremonies to perform for their stillborn children. Stillbirths are often treated as if they had never happened. Qualitative descriptive study. In-depth interviews, which were transcribed and content analysed, were conducted with a purposive sample of 16 women discharged from two teaching hospitals in Taiwan after they had a stillbirth. Families engaged in rituals for two underlying reasons: to benefit the deceased child and the immediate family. The meanings of the rituals for the child are presented through three themes: (i) sending the baby's spirit to a safe place, (ii) protecting it from suffering and (iii) preparing it for a better reincarnation. The meanings of rituals for the families are presented through four themes: (i) releasing parental guilt by doing their best for the deceased child, (ii) cutting bonds with the child, (iii) avoiding additional misfortune should they mishandle the funeral and (iv) praying for a successful subsequent pregnancy. Death-related rituals are highly culturally diverse. This study fills a gap about Asian cultures. Participating in rituals permits a mother to do something for her deceased child, helps relieve her guilt and lets her cope with the stillbirth. Rituals after a stillbirth can help a woman recover from grieving and allow her to hope for a successful subsequent pregnancy. Health professionals should discuss with bereaved parents what rituals they would like to perform and then respect their decisions. A continuum of care and support that exists from the prenatal diagnosis through the stillbirth and beyond is recommended for parents and families during this difficult time. © 2017 John Wiley & Sons Ltd.

Although boys outshine girls in a range of motor skills, there are no reported gender differences in motor performance during infancy. This study examined gender bias in mothers' expectations about their infants' motor development. Mothers of 11-month-old infants estimated their babies' crawling ability, crawling attempts, and motor decisions in a novel locomotor task-crawling down steep and shallow slopes. Mothers of girls underestimated their performance and mothers of boys overestimated their performance. Mothers' gender bias had no basis in fact. When we tested the infants in the same slope task moments after mothers' provided their ratings, girls and boys showed identical levels of motor performance. Copyright 2000 Academic Press.

Objective To find out the knowledge and behavior of mothers of under-fives about the technique of nursing and its related factors. Methods The study was perionned from September 20 to October 15, 1999 at Kelurahan Pisangan Baru, East Jakarta. The respondents were 101 mothers owning under-fives, attained by the multi-stage cluster random sampling method. Questionnaires were used and observation was made only on mothers who were suckling their child during the interview. Results Mother's knowledge about the way of suckling was found unsatisfactory in 46.5% although 51.5% of mothers revealed a good behavior. Statistical analysis showed no significant relationships between factors such as age, educational level, occupation, family income and mother's activity with mother's knowledge and behavior about the way of nursing their child. Conclusions There was no significant relationship between mother's knowledge and behavior about breastfeeding. Other factors beyond this studied factors should be taken into account.

Preventing mother-to-child transmission: factors affecting mothers' choice of feeding--a case study from Cameroon.

2004-11-01

This paper reports on factors influencing the decision of mothers regarding the type of feeding method for their babies in a rural setting in Cameroon. The aim of the study was to ascertain the proportion of mothers choosing the different methods of feeding, to determine the various factors influencing their choices, and to ascertain the relationships of these factors to their respective choices. Questionnaires were used on 108 HIV-positive mothers who had delivered babies and who were administered nevirapine at least 3 months prior to the study. A focus group discussion with mothers also took place. Findings were that more mothers (84%) chose breastfeeding than artificial feeding (16%), while a minority (4%) selected mixed feeding. Factors found to militate against artificial feeding were cost (69%), stigma (64%), family pressure (44%), inconvenience in preparation/administration (38%), prior education from health workers (23%), and loss of special attention from family (8%). On the other hand, advice of health worker (44%), ill health (19.5%), free milk (12.5%),job pressure (12.5%) and loss of beauty (12.5%) were found to militate against breastfeeding. A direct relationship was also found between age, educational level, income size, marital status and choice of feeding. Policies targeting stigma reduction and socio-cultural factors affecting the choice of feeding are needed to optimise uptake of the less risky methods of feeding which could in turn contribute to a reduction in transmission.

New birth weight reference standards customised to birth order and sex of babies from South India

2013-02-01

Full Text Available Abstract Background The foetal growth standards for Indian children which are available today suffer due to methodological problems. These are, for example, not adhering to the WHO recommendation to base gestational age on the number of completed weeks and secondly, not excluding mothers with risk factors. This study has addressed both the above issues and in addition provides birthweight reference ranges with regard to sex of the baby and maternal parity. Methods Data from the labour room register from 1996 to 2010 was obtained. A rotational sampling scheme was used i.e. the 12 months of the year were divided into 4 quadrants. All deliveries in January were considered to represent the first quadrant. Similarly all deliveries in April, July and October were considered to represent 2nd, 3rd and 4th quadrants. In each successive year different months were included in each quadrant. Only those mothers aged 20–39 years and delivered between 24 to 42 weeks gestational age were considered. Those mothers with obstetric risk factors were excluded. The reference standards were fitted using the Generalized Additive Models for Location Scale and Shape (GAMLSS method for Box – Cox t distribution with cubic spline smoothing. Results There were 41,055 deliveries considered. When women with risk factors were excluded 19,501 deliveries could be included in the final analysis. The male babies of term firstborn were found to be 45 g heavier than female babies. The mean birthweights were 2934 g and 2889.5 g respectively. Similarly, among the preterm babies, the first born male babies weighed 152 g more than the female babies. The mean birthweights were 1996 g and 1844 g respectively. In the case of later born babies, the term male babies weighed 116grams more than the females. The mean birth weights were 3085 grams and 2969 grams respectively. When considering later born preterm babies, the males outweighed the female babies by 111 grams. The

Very preterm infants are known to be at risk of developmental disabilities and behavioural disorders. This condition is supposed to alter mother-infant interactions. Here we hypothesize that the parental coping with the very preterm birth may greatly influence mother-infant interactions. 100 dyads were included in 3 university hospitals in France. Preterm babies at higher risk of neurodevelopmental sequelae (PRI>10) were excluded to target the maternal determinants of mother-infant interaction. We report the follow-up of this cohort during 1 year after very preterm birth, with regular assessment of infant somatic state, mother psychological state and the assessment of mother-infant interaction at 12 months by validated scales (mPPQ, HADS, EPDS, PRI, DDST and PIPE). We show that the intensity of post-traumatic reaction of the mother 6 months after birth is negatively correlated with the quality of mother-infant interaction at 12 months. Moreover, the anxious and depressive symptoms of the mother 6 and 12 months after birth are also correlated with the quality of mother-infant interaction at 12 months. By contrast, this interaction is not influenced by the initial affective state of the mother in the 2 weeks following birth. In this particular population of infants at low risk of sequelae, we also show that the quality of mother-infant interaction is not correlated with the assessment of the infant in the neonatal period but is correlated with the fine motor skills of the baby 12 months after birth. This study suggests that mothers' psychological condition has to be monitored during the first year of very preterm infants' follow-up. It also suggests that parental interventions have to be proposed when a post-traumatic, anxious or depressive reaction is suspected.

To explore prospective mothers' perspectives regarding antenatal consultations by neonatology teams for threatened preterm delivery. In a prospective multicenter study, women at risk of preterm delivery between 26 and 32 weeks of gestational age were surveyed during the 72 hours following their antenatal consultation. The questionnaire used was developed and validated during a single-center study. Over 18 months, 229 mothers completed the survey (73% response rate), at a median gestational age of 30 weeks. Spouses/partners were present for 49% of consultations. Most women (90%) reported a positive experience. They found it important to discuss the outcomes of prematurity (96%), but 39% of them reported receiving too much information. Women wanted their spouse/partner to be present (71%) and wished to discuss parental concerns: their roles as mother of a premature baby (82%), their integration in their baby's care (83%), and a better understanding of the neonatal intensive care unit (NICU) environment, including antenatal NICU visits (69%). The majority (56%) wanted a follow-up consultation: this was less likely if a NICU visit had been offered (P parents with child-centered information. Although clinicians follow these guidelines, mothers want personalized information focusing on their individual concerns and questions, such as what they can do for their baby, how NICUs work, and the integration of their family.

We investigated whether attachment quality is related to infant-mother dyadic patterns in monitoring animated social situations. Sixty 12-month-old infants and their mothers participated in an eye-tracking study in which they watched abstractly depicted distress interactions involving the separation of a "baby" and a "parent" character followed by reunion or further separation of the two characters. We measured infants' and their mothers' relative fixation duration to the two characters in the animations. We found that infant attachment disorganization moderated the correspondence between the monitoring patterns of infant-mother dyads during the final part of the animations resulting in reunion or separation. Organized infants and their mothers showed complementary monitoring patterns: the more the mothers focused their attention on the "baby" character, the more the infants focused their attention on the "parent" character, and vice versa. Disorganized infant-mother dyads showed the opposite pattern although the correlation was nonsignificant: mothers and their infants focused on the same character. The attachment-related differences in the nature of the synchrony in the attentional processes of infants and their mothers suggest that by 12 months the dyads' representations of social situations reflect their shared social-emotional experiences.

The main objective of the paper is to capture the behavior of a vehicle on a race circuit, depending on the different inflation pressures of the tires (underpressure and overpressure). Taking into account that in the cornering the forces and the moments of inertia rise due the vehicle mass, and an inertial force decomposes in two components, one in the longitudinal plane and one in the transverse plane, the work aims the assessing the lateral forces that appear, to the contact between the tires and the tread, depending on the inflation pressure. The results have a graphic interpretation, enabling a comparative study of them. Results have been obtained regarding the lateral tire forces that occur between the tire and the road. The differences between these forces were particularly noticeable in cornering, and the differences between these forces were interpreted according to the tire inflation pressure.

The foetal growth standards for Indian children which are available today suffer due to methodological problems. These are, for example, not adhering to the WHO recommendation to base gestational age on the number of completed weeks and secondly, not excluding mothers with risk factors. This study has addressed both the above issues and in addition provides birthweight reference ranges with regard to sex of the baby and maternal parity. Data from the labour room register from 1996 to 2010 was obtained. A rotational sampling scheme was used i.e. the 12 months of the year were divided into 4 quadrants. All deliveries in January were considered to represent the first quadrant. Similarly all deliveries in April, July and October were considered to represent 2nd, 3rd and 4th quadrants. In each successive year different months were included in each quadrant. Only those mothers aged 20-39 years and delivered between 24 to 42 weeks gestational age were considered. Those mothers with obstetric risk factors were excluded. The reference standards were fitted using the Generalized Additive Models for Location Scale and Shape (GAMLSS) method for Box-Cox t distribution with cubic spline smoothing. There were 41,055 deliveries considered. When women with risk factors were excluded 19,501 deliveries could be included in the final analysis. The male babies of term firstborn were found to be 45 g heavier than female babies. The mean birthweights were 2934 g and 2889.5 g respectively. Similarly, among the preterm babies, the first born male babies weighed 152 g more than the female babies. The mean birthweights were 1996 g and 1844 g respectively.In the case of later born babies, the term male babies weighed 116 grams more than the females. The mean birth weights were 3085 grams and 2969 grams respectively. When considering later born preterm babies, the males outweighed the female babies by 111 grams. The mean birthweights were 2089 grams and 1978 grams

METHODS: According to provincial health directorate, the number of women who was pregnant on 30 June 2010 is 1,532, and 958 of these women have experienced at least one pregnancy previously. The universe of this conducted cross-sectional type research has been comprised of 958 women who had experienced pregnancy once at least. A sample was not selected in the study; it was aimed to reach the whole of universe. The data have been gathered, after getting necessary permissions, between the dates of 15 March and ndash; 21 June 2010 with a questionnaire and face to face. The data were analyzed in SPSS 10,5 package program. RESULTS: Congenital malformation prevalence in Burdur is 4,2%. Delivering babies with congenital malformation is 2,5 times (OR:1,1 and ndash;5,4 more in mothers 35 years of age or older with reference to 34 years of age and younger mothers. Delivering babies with congenital malformation is 2,9 times greater (OR:1,4 and ndash;5,7 in fathers whose education level are primary and under with reference to fathers whose education level are secondary and higher; 8 times greater (OR:2,2 and ndash;21,3 in mothers who had stillbirths with reference to mothers who had not stillbirths; 3,4 times greater (OR:1,0 and ndash;11,5 in mothers whose children died before the age of 5 with reference to mothers whose children not died before the age of 5. CONCLUSiON: In conclusion, congenital malformation prevalence is similar with the data of Turkey. For prevention of congenital malformations prenatal care as sufficient number and quality should be provided to the mothers who were over 35 years and above, child death below 5 years or had stillbirths and had educatiol level as primary education or less.

Full Text Available Pregnant women are at high risk for infection by pathogens. Vertical transmission of infectious agents, such as Zika, hepatitis B, and cytomegalovirus during pregnancy, remains a public health problem, associated with dire outcomes for the neonate. Thus, a safe prophylactic and therapeutic approach for protecting the mother and the neonate from infections remains a high priority. Our work is focused on better understanding the safety and efficacy determinants of IgG antibody preparations when used during pregnancy to benefit the mother and her baby. Using pregnant guinea pigs, we demonstrated that biodistribution of administered IgG to the fetus increases with gestation and results in lower maternal and higher fetal antibody concentrations as pregnancy progresses. Data suggests that partition of antibody immunotherapy to the fetal compartment may contribute to a lower maternal exposure (as measured by the AUC and a shorter mean residence time of the IgG therapeutic at the end of pregnancy compared to nonpregnant age-matched controls, irrespective of the administered dose. Our studies provide insights on the importance of selecting an efficacious dose in pregnancy that takes into account IgG biodistribution to the fetus. The use of appropriate animal models of placental transfer and infectious disease during pregnancy would facilitate pharmacokinetic modeling to derive a starting dose in clinical trials.

Objective: To assess the frequency of hepatitis B markers in pregnant females and estimate rate and potential risk factors for transmission to newborn. Place: Department of pediatrics and gynecology and obstetrics, Dow Medical College and Civil Hospital, and Sobraj Maternity Home, Karachi. Subjects and Methods: Two hundred and forty-five pregnant females admitted at term between September 1993 to April 1999 were screened for HbsAG and HbeAg using a rapid immuno chromatographic test (ICT), on whole blood. Venous blood samples were collected simultaneously from all these patients and every fifth specimen was analysed by ELISA method. Babies of mother with Hbs or Hbe Antigenemia were also tested at birth for both the antigens. The risk factors studied included maternal age, parity history of previous abortion, transfusion, operation, drug addiction and liver diseases in the family. Results: Eight out of 245 mothers tested (3.26%) were positive for HbsAg and one out of eight mothers (12.5%) positive for HbsAb and HbeAg by ICT method. Results of 52 samples re-tested by ELISA were comparable with ICT. All babies born to mother with HBV infection were negative for these markers. Increasing maternal age, number of pregnancies, repeated injections and addition emerged as significant risk factors. Conclusion: Vertical transmission in the early prenatal period is either minimum suggesting horizontal transmission in majority of children infected through mother or delayed sero-conversion in babies infected through prenatal route. This requires a prospective longitudinal study to measure the outcome. (author)

Energy requirements of tire pulling.

We have investigated the effect using walking poles and pulling tires at 4 and 6 km·h-1 (1.11 and 1.67 m·s-1) speeds on oxygen uptake (V̇O2) and heart rate. Eleven subjects, 6 males, with a mean (SD) age of 25.2 (6.9) years participated in field tests involving walking without poles, walking with poles and tire pulling with poles. Increasing the load caused the largest increases in energy demand, more than 4 MET. Speed increase also caused substantial energy increase, approximately 4 MET. Increasing the inclination only modestly increased the oxygen uptake, approximately 2 MET. In both level walking and uphill walking, using poles marginally increased oxygen uptake compared to working without poles. Pulling one tire (12.5 kg) required an oxygen uptake of 27 (4) mL·kg-1·min-1 at 4 km·h-1 and 0% inclination. Adding one more tire (6 kg) drove the oxygen uptake further up to 39 (4) mL·kg-1·min-1. This is close to the requirement of level running at 10.5 km·h-1. Pulling both tires at 6 km·h-1 and 5% inclination required a V̇O2 of 54 (6) mL·kg-1·min-1, equal to running uphill at 5% inclination and 12.5 km·h-1 speed. Heart rate rose comparably with oxygen uptake. At 4 km·h-1 and 0% inclination the increase was 29 bpm, from 134 (21) to 163 (22) bpm when going from pulling one tire to two tires. In the hardest exercise, 6 km·h-1 and 5% inclination, heart rate reached 174 (14) bpm. The study showed that tire pulling even at slow speeds has an energy requirement that is so large that the activity may be feasible as endurance training.

Rubber friction and tire dynamics

International Nuclear Information System (INIS)

Persson, B N J

2011-01-01

We propose a simple rubber friction law, which can be used, for example, in models of tire (and vehicle) dynamics. The friction law is tested by comparing numerical results to the full rubber friction theory (Persson 2006 J. Phys.: Condens. Matter 18 7789). Good agreement is found between the two theories. We describe a two-dimensional (2D) tire model which combines the rubber friction model with a simple mass-spring description of the tire body. The tire model is very flexible and can be used to accurately calculate μ-slip curves (and the self-aligning torque) for braking and cornering or combined motion (e.g. braking during cornering). We present numerical results which illustrate the theory. Simulations of anti-blocking system (ABS) braking are performed using two simple control algorithms.

The 2010 earthquake in Haiti displaced about 1.5 million people, many of them into camps for internally displaced persons. It was expected that disruption of breastfeeding practices would lead to increased infant morbidity, malnutrition and mortality. Haiti's health ministry and the United Nations Children's Fund, in collaboration with local and international nongovernmental organizations, established baby tents in the areas affected by the earthquake. The tents provided a safe place for mothers to breastfeed and for non-breastfed infants to receive ready-to-use infant formula. Such a large and coordinated baby tent response in an emergency context had never been mounted before anywhere in the world. Baby tents were set up in five cities but mainly in Port-au-Prince, where the majority of Haiti's 1555 camps for displaced persons had been established. Between February 2010 and June 2012, 193 baby tents were set up; 180 499 mother-infant pairs and 52 503 pregnant women were registered in the baby tent programme. Of infants younger than 6 months, 70% were reported to be exclusively breastfed and 10% of the "mixed feeders" moved to exclusive breastfeeding while enrolled. In 2010, 13.5% of registered infants could not be breastfed. These infants received ready-to-use infant formula. Thanks to rapid programme scale-up, breastfeeding practices remained undisrupted. However, better evaluation methods and comprehensive guidance on the implementation and monitoring of baby tents are needed for future emergencies, along with a clear strategy for transitioning baby tent activities into facility and community programmes.

Little is known about learning/adherence after different baby massage teaching strategies. We compared the learning/adherence after two strategies. Twenty mothers from the group manual-course (GMC) and 20 from the group manual-orientations (GMO) received a booklet. GMC participated in a course during the third trimester. GMO received verbal instructions during the postpartum hospital stay. Multiple-choice and practical tests assessed learning (GMC: performing strokes on a doll; GMO: on the baby). Adherence was measured 3 months after childbirth. No differences were found between the groups in learning/adherence. Both teaching strategies showed similar and positive results. © 2014, Wiley Periodicals, Inc.

Environmental impact caused by incorrect discard of tires

2015-11-01

Full Text Available Tires are wastes that need special treatment, because when buried whole, its shape facilitates the accumulation of gases from the decomposition of other waste and in case of emerge surface provides shelter for diseases. Thus, this research aimed to provide information about the environmental impacts caused by the improper disposal of unserviceable tires and about some techniques for reusing and recycling them. We opted for the literature search using databases SCIELO, GOOGLE SCHOLAR, CAPES journals, resolutions of the MMA, the ANIP and regulations of IBAMA instructions. The consultation material comprises a period from 1992 to 2015 with the following descriptors: industrial waste; laws of tires; environmental impacts caused by improper disposal of tires and technological alternatives usable by tires and scrap therefore improper disposal of scrap tires can cause negative impacts such as floods, by reducing the flow capacity of water bodies and drains. In contrast, after use, the tire can undergo reform and be reused, but the wear out is completely characterized as waste tire and the correct disposal are the possible ways of recycling. Thus it is very important compliance of laws that deal with the proper disposal of tires.

Rural, low-income pregnant women and their children are at high risk for poor oral health and have low utilization rates of dental care. The Baby Smiles study was designed to increase low-income pregnant women's utilization of dental care, increase young children's dental care utilization, and improve home oral health care practices. Baby Smiles was a five-year, four-site randomized intervention trial with a 2 × 2 factorial design. Four hundred participants were randomly assigned to one of four treatment arms in which they received either brief Motivational Interviewing (MI) or health education (HE) delivered during pregnancy and after the baby was born. In the prenatal study phase, the interventions were designed to encourage dental utilization during pregnancy. After childbirth, the focus was to utilize dental care for the infant by age one. The two primary outcome measures were dental utilization during pregnancy or up to two months postpartum for the mother, and preventive dental utilization by 18 months of age for the child. Medicaid claims data will be used to assess the primary outcomes. Questionnaires were administered at enrollment and 3, 9 and 18 months postpartum (study end) to assess mediating and moderating factors. This trial can help define the most effective way to provide one-on-one counseling to pregnant women and new mothers regarding visits to the dentist during pregnancy and after the child is born. It supports previous work demonstrating the potential of reducing mother-to-child transmission of Streptococcus mutans and the initiation of dental caries prevention in early childhood.

Nonlinear Analysis and Modeling of Tires

Science.gov (United States)

Noor, Ahmed K.

1996-01-01

The objective of the study was to develop efficient modeling techniques and computational strategies for: (1) predicting the nonlinear response of tires subjected to inflation pressure, mechanical and thermal loads; (2) determining the footprint region, and analyzing the tire pavement contact problem, including the effect of friction; and (3) determining the sensitivity of the tire response (displacements, stresses, strain energy, contact pressures and contact area) to variations in the different material and geometric parameters. Two computational strategies were developed. In the first strategy the tire was modeled by using either a two-dimensional shear flexible mixed shell finite elements or a quasi-three-dimensional solid model. The contact conditions were incorporated into the formulation by using a perturbed Lagrangian approach. A number of model reduction techniques were applied to substantially reduce the number of degrees of freedom used in describing the response outside the contact region. The second strategy exploited the axial symmetry of the undeformed tire, and uses cylindrical coordinates in the development of three-dimensional elements for modeling each of the different parts of the tire cross section. Model reduction techniques are also used with this strategy.

The vehicle refurbished tire test system was constructed, got load-deformation, load-stiffness, and load-compression ratio property laws of engineering vehicle refurbished tire under the working condition of static state and ground contact, and built radial direction loading deformation mathematics model of 26.5R25 engineering vehicle refurbished tire. The test results show that radial-direction and side-direction deformation value is a little less than that of the new tire. The radial-direction stiffness and compression ratio of engineering vehicle refurbished tire were greatly influenced by radial-direction load and air inflation pressure. When load was certain, radial-direction stiffness would increase with air inflation pressure increasing. When air inflation pressure was certain, compression ratio of engineering vehicle refurbished tire would enlarge with radial-direction load increasing, which was a little less than that of the new and the same type tire. Aging degree of old car-case would exert a great influence on deformation property of engineering vehicle refurbished tire, thus engineering vehicle refurbished tires are suitable to the working condition of low tire pressure and less load.

Some national guidelines recommend the use of water alone for napkin cleansing. Yet, there is a readiness, amongst many parents, to use baby wipes. Evidence from randomised controlled trials, of the effect of baby wipes on newborn skin integrity is lacking. We conducted a study to examine the hypothesis that the use of a specifically formulated cleansing wipe on the napkin area of newborn infants (skin hydration when compared with using cotton wool and water (usual care). A prospective, assessor-blinded, randomised controlled equivalence trial was conducted during 2010. Healthy, term babies (n=280), recruited within 48 hours of birth, were randomly assigned to have their napkin area cleansed with an alcohol-free baby wipe (140 babies) or cotton wool and water (140 babies). Primary outcome was change in hydration from within 48 hours of birth to 4 weeks post-birth. Secondary outcomes comprised changes in trans-epidermal water loss, skin surface pH and erythema, presence of microbial skin contaminants/irritants at 4 weeks and napkin dermatitis reported by midwife at 4 weeks and mother during the 4 weeks. Complete hydration data were obtained for 254 (90.7 %) babies. Wipes were shown to be equivalent to water and cotton wool in terms of skin hydration (intention-to-treat analysis: wipes 65.4 (SD 12.4) vs. water 63.5 (14.2), p=0.47, 95% CI -2.5 to 4.2; per protocol analysis: wipes 64.6 (12.4) vs. water 63.6 (14.3), p=0.53, 95% CI -2.4 to 4.2). No significant differences were found in the secondary outcomes, except for maternal-reported napkin dermatitis, which was higher in the water group (p=0.025 for complete responses). Baby wipes had an equivalent effect on skin hydration when compared with cotton wool and water. We found no evidence of any adverse effects of using these wipes. These findings offer reassurance to parents who choose to use baby wipes and to health professionals who support their use. Current Controlled Trials ISRCTN86207019.

Personality differences between surrogate mothers (SMs) who gestate and relinquish and intended mothers (IMs) who commission a genetically related or unrelated baby have been unexplored in the UK. Furthermore, the psychological effects of the arrangement have not been determined in a prospective longitudinal study, making this the first quantitative report of psychological functioning in SMs and IMs. SMs and IMs (n = 81: 61 surrogate, 20 intended) undergoing genetic or gestational surrogacy (4 groups) were assessed by postal questionnaire during the first, second and third trimesters of pregnancy. Those with a positive outcome were assessed again in the first week, at 6 weeks and 6 months post-delivery of the surrogate baby. There were no significant differences between or within SM and IM groups on personality characteristics. Social support, marital harmony and state anxiety differed significantly (to P pregnancy and the baby were also observed between groups during pregnancy (to P surrogate arrangement are notable and occur over an extended period of time. It also shows that psychological screening and support prior to, during and following surrogacy is indicated.

Directory of Open Access Journals (Sweden)

Ateekh-Ur-Rehman

2017-02-01

Full Text Available In response to the present dynamic market, automobile manufacturing industries are constantly evaluating and improving their manufacturing strategies to stay competitive. It is also evident that they evaluate those strategies considering multiple criteria. In one such case, an automobile project manager has to ensure that the selected tire (among the available alternatives complies with the prospective automobile’s performance. This paper presents an approach for the assessment of alternative automobile tires taking into account multiple criteria, such as tire sustainability, tire road performance, environmental issues, tire purchase cost and tire road grip. The presented approach is quite helpful to any decision maker who is interested not only in ranking alternatives but also in establishing the superiority of an alternative over others. The approach also helps to specify the position of each alternative with respect to ideal solution. A case illustration is used to demonstrate an application of the approach.

The beneficial effects of breastfeeding for mothers and babies are well recognized. When maternal breast milk is not available in sufficient quantity, donor breast milk is recommended as an alternate source of nutrition, particularly in preterm and other high-risk infants. Australia lags behind the rest of the developed world in establishing and promoting human milk banks; there is no human milk bank in South Australia and little is known concerning mothers' perceptions of using human milk banks in that state. This study explored mothers' knowledge of and attitudes toward human milk banks, to inform the development of human milk banking policies and guidelines in South Australia should a milk bank be established. In-depth semistructured interviews were conducted with 12 mothers who were breastfeeding and/or had preterm or sick babies. In addition, 2 focus groups were conducted-1 with breastfeeding mothers as potential donors (n = 5) and the other with mothers of preterm or high-risk infants (n = 4)-to answer questions raised by early analysis of the individual interview data. Breastfeeding mothers, as potential donors, unanimously supported donating their breast milk to a human milk bank, provided it would be easy (especially if required to drop off milk) and not overly time consuming. Mothers of preterm or sick infants would use a human milk bank if they were assured the milk was safe and appropriate for their babies. Study participants would welcome having access to a human milk bank for both donating and receiving milk in South Australia.

Use of shredded tire chips and tire crumbs as packing media in trickling filter systems for landfill leachate treatment.

Mondal, B; Warith, M A

2008-08-01

Scrap tire stockpiles are breeding grounds for pests, mosquitoes and west Nile viruses and, thereby, become a potential health risk. This experimental study was carried out in six stages to determine the suitability of shredded tire materials in a trickling filter system to treat landfill leachate. Biochemical oxygen demand (BOD5), chemical oxygen demand (COD) and NH3-N removals were obtained in the range of 81 to 96%, 76 to 90% and 15 to 68%, respectively. The removal of organics appears to be largely related to total dissolved solids reduction in leachate. A sudden increase, from time to time, in organic content of effluent could be attributed to biomass sloughing and clogging in the trickling filters. However, tire crumbs exhibited more consistent organics removal throughout the experimental program. Due to the high surface area of shredded tire chips and crumbs, a layer of biomass, 1-2 mm thick, was attached to them and was sloughed off at an interval of 21 days. Apart from that, as shredded tires are comparatively cheaper than any other usable packing material, tire chips and tire crumbs appeared to be quite promising as packing media in trickling filters for landfill leachate treatment.

To study the impact of postnatal depression on the quality of life of young French mothers and to evaluate if the gender of their child influences this. Postnatal depression (PND) constitutes a major public health problem considering its high prevalence and consequences upon quality of life and parental skills. This research is a cross-sectional study during the postnatal period. This study was carried out during a two-month period. Data were collected by interview and questionnaires. The authors compared the prevalence rate of PND and life quality in a cohort of 181 women and measured the short-term impact of the child's birth. Postnatal depression strongly negatively influences all dimensions of life quality explored through the SF36, e.g. physical functioning (PF), physical Role (RP), bodily pain (BP), mental health (MH), emotional role (RE), social functioning (SF), vitality (VT), general health (GH), standardized physical component (PCS) and standardized mental component (MCS). The baby's gender (having a boy) also significantly reduces quality of life, irrespective of depressive state. There is a relationship between baby gender and PND. This research is the first to show that the birth of a boy reduces several dimensions of the mothers' quality of life. The importance of the impairment of quality of life in case of PND, as well as its effects on mother-child interaction, could justify prevention programs and early psychotherapeutic care. Further research needs to explore the effectiveness of programmes targeting the construction of parenting skills as a preventative measure against PND, especially for parents of boys.

The tire is a significant part for control of a vehicle. For a well-working brake system the contact properties between the tire and the ground is the limiting factor for a safe braking. To get optimal performance it is important that the system can utilize all friction resources. The brush tire model was a popular method in the 1960's and 1970's before the empirical approaches became dominating. The brush model gives an educational interpretation of the physics behind the tire behavi...

2008-11-01

Full Text Available Every year, 3-5% of pregnant mothers in South Africa lose their babies to a stillbirth or neonatal death. These mothers need adequate services to prevent complications in their grieving process. Most of these babies are lost in hospital settings, so the treatment medical staff provide is vital. This study examined mothers’ experiences of accessing hospital, religious, formal and social services after a stillbirth or neonatal death. An exploratory research design was used to conduct applied research. A semi-structured interview schedule was used with a sample of 15 mothers who had lost a baby in the last 5 years. The findings were analysed quantitatively and qualitatively. The primary focus of this article is the quantitative findings relating to hospital services. The sample was small and these results cannot be generalised, but some conclusions are reached and recommendations are made to service providers in hospitals working with mothers who have lost babies. Mothers generally experienced the support services from hospitals as inadequate, compared to what hospitals could offer. Mothers that receive support after the loss of a baby generally cope better. This support thus assists them in the grieving process. Hospital staff can be trained to provide these services. Opsomming In Suid-Afrika verloor 3-5% swanger moeders hulle babas deur stilgeboorte of neonatale dood. Hierdie moeders benodig voldoende dienste om komplikasies in die rouproses te verhoed.

Tarasov, V. N.; Boyarkina, I. V.

2018-01-01

Analytical calculations in the pneumatic tire theory are more preferable in comparison with experimental methods. The method of section of a pneumatic tire shell allows to obtain equations of intensities of internal forces in carcass elements and bead rings. Analytical dependencies of intensity of distributed forces have been obtained in tire equator points, on side walls (poles) and pneumatic tire bead rings. Along with planes in the capacity of secant surfaces cylindrical surfaces are used for the first time together with secant planes. The tire capacity equation has been obtained using the method of section, by means of which a contact body is cut off from the tire carcass along the contact perimeter by the surface which is normal to the bearing surface. It has been established that the Laplace equation for the solution of tasks of this class of pneumatic tires contains two unknown values that requires the generation of additional equations. The developed computational schemes of pneumatic tire sections and new equations allow to accelerate the pneumatic tire structure improvement process during engineering.

Intestinal colic in newborn babies: incidence and methods of proceeding applied by parents

Directory of Open Access Journals (Sweden)

Anna Lewandowska

2017-06-01

Full Text Available Introduction: Intestinal colic is one of the more frequent complaints that a general practitioner and paediatrician deal with in their work. 10-40% of babies formula fed and 10-20% breast fed are stricken by this complaint. A colic attack appears suddenly and very quickly causes energetic, squeaky cry or even scream. Colic attacks last for a few minutes and appear every 2-3 hours usually in the evenings. Specialist literature provides numerous definitions of intestinal colic. The concept was introduced for the first time to paediatric textbooks over 250 years ago. One of the most accurate definitions describe colic as recurring attacks of intensive cry and anxiety lasting for more than 3 hours a day, 3 days a week within 3 weeks. Care of a baby suffering from an intestinal colic causes numerous problems and anxiety among parents, therefore knowledge of effective methods to combat this complaint is a challenge for contemporary neonatology and paediatrics. The aim of the study is to estimate the incidence of intestinal colic in newborn babies formula and breast fed as well as to assess methods of proceeding applied by parents and analyze their effectiveness. Material and methods: The research involved 100 newborn babies breast fed and 100 formula fed, and their parents. The research method applied in the study was a diagnostic survey conducted by use of a questionnaire method. Results: Among examined newborn babies that were breast fed, 43% have experienced intestinal colic, while among those formula fed 30% have suffered from it. The study involved 44% new born female babies and 56% male babies. 52% of mothers were 30-34 years old, 30% 35-59 years old, and 17% 25-59 years old. When it comes to families, the most numerous was a group in good financial situation (60%. The second numerous group was that in average financial situation (40%. All the respondents claimed that they had the knowledge on intestinal colic and the main source of knowledge

Pogrebna, Ganna; Oswald, Andrew J; Haig, David

2018-03-01

Using ultrasound scan data from paediatric hospitals, and the exogenous 'shock' of learning the gender of an unborn baby, the paper documents the first causal evidence that offspring gender affects adult risk-aversion. On a standard Holt-Laury criterion, parents of daughters, whether unborn or recently born, become almost twice as risk-averse as parents of sons. The study demonstrates this in longitudinal and cross-sectional data, for fathers and mothers, for babies in the womb and new-born children, and in a West European nation and East European nation. These findings may eventually aid our understanding of risky health behaviors and gender inequalities. Copyright © 2018 The Authors. Published by Elsevier B.V. All rights reserved.

To examine oxidative & nitrosative stress (O&NS) biomarkers at the end of term in relation to perinatal affective symptoms, neuro-immune biomarkers and pregnancy-related outcome variables. We measured plasma advanced oxidation protein products (AOPP), nitric oxide metabolites (NOx), total radical trapping antioxidant parameter (TRAP), -sulfhydryl (-SH), peroxides (LOOH) and paraoxonase (PON)1 activity in pregnant women with and without prenatal depression and non-pregnant controls. Pregnancy is accompanied by significantly increased AOPP and NOx, and lowered TRAP, -SH and LOOH. Increased O&NS and lowered LOOH and -SH levels are associated with prenatal depressive and physio-somatic symptoms (fatigue, pain, dyspepsia, gastro-intestinal symptoms). Increased AOPP and NOx are significantly associated with lowered -SH, TRAP and zinc, and with increased haptoglobin and C-reactive protein levels. Increased O&NS and lowered TRAP and PON 1 activity, at the end of term predict mother (e.g. hyperpigmentation, labor duration, caesarian section, cord length, breast milk flow) and baby (e.g. sleep and feeding problems) outcome characteristics. Pregnancy is accompanied by interrelated signs of O&NS, lowered antioxidant defenses and activated neuro-immune pathways. Increased O&NS at the end of term is associated with perinatal depressive and physio-somatic symptoms and may predict obstetric and behavioral complications in mother and baby.

Breast feeding provides a lot of short and long-term benefits for the mother and the baby. It prevents the baby of gastrointestinal, urinary and respiratory infections, atopical conditions and assures long-term protection of cardiovascular and metabolic diseases. The breast feeding decreases the risk for the mother of ovary and breast carcinoma and creates a positive emotional bond between the mother and the baby Mother's milk is a species specific; its content is relatively stable regardless of mother's age race, way and place of living. Mother's milk is not sterile. There is a 10 year international trial held in Spanish and Finnish universities. It has identified and count all microorganisms in mother's milk (more than 700) and proved that their content and quantity varies according the age of the baby. Mother's milk is a source of lactobacillus for baby's intestines and most of them have probiotic potential. Lactobacillus fermentum Lc40 (hereditum) is isolated from mother's milk. It has a good viability in gastrointestinal system, high level of adhesion to intestinal epithelium cells, produces glutation--strong antioxidant, good antibacterial activity to entero-pathogens and potential of increasing the immunologic response. Clinical trials reveal that Lactobacillus fermentum plays important role to microflora balance of mother's milk in mastitis during lactation. Many trials estimating the efficiency of lactobacillus fermentum in prevention and treatment of acute and subacute mastitis have been carried out. The results of them open a new door in front of us in the treatment of these conditions--treatment with probiotics instead of antibiotics.

Constraints to exclusive breastfeeding practice among breastfeeding mothers in Southwest Nigeria: implications for scaling up

Agunbiade Ojo M

2012-04-01

Full Text Available Abstract Background The practice of exclusive breastfeeding is still low despite the associated benefits. Improving the uptake and appropriating the benefits will require an understanding of breastfeeding as an embodied experience within a social context. This study investigates breastfeeding practices and experiences of nursing mothers and the roles of grandmothers, as well as the work-related constraints affecting nurses in providing quality support for breastfeeding mothers in Southwest Nigeria. Methods Using a concurrent mixed method approach, a structured questionnaire was administered to 200 breastfeeding mothers. In-depth interviews were also held with breastfeeding mothers (11, nurses (10 and a focus group discussion session with grandmothers. Results Breastfeeding was perceived as essential to baby's health. It strengthens the physical and spiritual bond between mothers and their children. Exclusive breastfeeding was considered essential but demanding. Only a small proportion (19% of the nursing mothers practiced exclusive breastfeeding. The survey showed the major constraints to exclusive breastfeeding to be: the perception that babies continued to be hungry after breastfeeding (29%; maternal health problems (26%; fear of babies becoming addicted to breast milk (26%; pressure from mother-in-law (25%; pains in the breast (25%; and the need to return to work (24%. In addition, the qualitative findings showed that significant others played dual roles with consequences on breastfeeding practices. The desire to practice exclusive breastfeeding was often compromised shortly after child delivery. Poor feeding, inadequate support from husband and conflicting positions from the significant others were dominant constraints. The nurses decried the effects of their workload on providing quality supports for nursing mothers. Conclusion Breastfeeding mothers are faced with multiple challenges as they strive to practice exclusive breastfeeding. Thus

An Analytical Tire Model with Flexible Carcass for Combined Slips

Directory of Open Access Journals (Sweden)

Nan Xu

2014-01-01

Full Text Available The tire mechanical characteristics under combined cornering and braking/driving situations have significant effects on vehicle directional controls. The objective of this paper is to present an analytical tire model with flexible carcass for combined slip situations, which can describe tire behavior well and can also be used for studying vehicle dynamics. The tire forces and moments come mainly from the shear stress and sliding friction at the tread-road interface. In order to describe complicated tire characteristics and tire-road friction, some key factors are considered in this model: arbitrary pressure distribution; translational, bending, and twisting compliance of the carcass; dynamic friction coefficient; anisotropic stiffness properties. The analytical tire model can describe tire forces and moments accurately under combined slip conditions. Some important properties induced by flexible carcass can also be reflected. The structural parameters of a tire can be identified from tire measurements and the computational results using the analytical model show good agreement with test data.

Jadva, Vasanti; Murray, Clare; Lycett, Emma; MacCallum, Fiona; Golombok, Susan

2003-10-01

This study examined the motivations, experiences and psychological consequences of surrogacy for surrogate mothers. Thirty-four women who had given birth to a surrogate child approximately 1 year previously were interviewed by trained researchers, and the data rated using standardized coding criteria. Information was obtained on: (i) reasons for the woman's decision to become a surrogate mother; (ii) her retrospective view of the relationship with the commissioning couple before the pregnancy, during the pregnancy, and after the birth; (iii) her experiences during and after relinquishing the child; and (iv) how others reacted to her decision to become a surrogate mother. It was found that surrogate mothers do not generally experience major problems in their relationship with the commissioning couple, in handing over the baby, or from the reactions of those around them. The emotional problems experienced by some surrogate mothers in the weeks following the birth appeared to lessen over time. Surrogate mothers do not appear to experience psychological problems as a result of the surrogacy arrangement.

A Novel Strain-Based Method to Estimate Tire Conditions Using Fuzzy Logic for Intelligent Tires

Directory of Open Access Journals (Sweden)

Daniel Garcia-Pozuelo

2017-02-01

Full Text Available The so-called intelligent tires are one of the most promising research fields for automotive engineers. These tires are equipped with sensors which provide information about vehicle dynamics. Up to now, the commercial intelligent tires only provide information about inflation pressure and their contribution to stability control systems is currently very limited. Nowadays one of the major problems for intelligent tire development is how to embed feasible and low cost sensors to obtain reliable information such as inflation pressure, vertical load or rolling speed. These parameters provide key information for vehicle dynamics characterization. In this paper, we propose a novel algorithm based on fuzzy logic to estimate the mentioned parameters by means of a single strain-based system. Experimental tests have been carried out in order to prove the suitability and durability of the proposed on-board strain sensor system, as well as its low cost advantages, and the accuracy of the obtained estimations by means of fuzzy logic.

Baby boom generation at the retirement onset

Stojilković Jelena

2010-01-01

Full Text Available Sudden increase in the number of live births after the Second World War due to an increase in fertility rates has led to the formation of cohorts with specific characteristics or baby boom generation. This generation is unique in the history of the demographic phenomenon that has affected and affects the functioning of many segments of society. The aim of this paper is to assess structure of baby boomers who are few years away from retirement, using demographic data. Impact of baby boomer age structure of current and future retirees is described with a graphical display of current and projected age pyramid of baby boomers. Demographic pattern that women live longer than men is evident in the projected pyramid. In addition, the number of baby boomers will lead to a "younger" old population. The imbalance in the number of men and women pensioners, as well as older cohorts of women and female baby boomers was analyzed. As a result, an increasing trend of women's age pensioners who are members of the baby boom generation was clearly observed, which is opposite to the older cohort of women who often were family pensioners. Different circumstances and conditions in which female boomers lived and worked will form a new "pension model" because they will gain their benefits as well as men, for the first time in significant number, unlike their mothers, which gained the right to retire after they become widows. Number of women age pensioners is getting greater comparing to men, as the result of changes in the economic activities of women in the last half of the 20th century. When baby boomers retire and exit the working population, this will create a vacuum, because the numerically smaller generations will enter working population, while the sudden and very shortly, the number of population older than 60 or 65 will increase, most of them will likely to acquire the right to a pension. It is undeniable that baby boomers had impact on demographic structure

Full Text Available An experimental work was undertaken to study the effect of rubber tires on the geotechnical properties of a dredged sediment, using a mixing ratio of large size. For comparison, two types of soil were studied (dredged sediment from Fergoug dam and Tizi Tuff from the north west of Algeria. Taking into account the high compressibility and the low water absorption of the rubber tires, grain size analysis, density, Atterberg limits analysis, chemical composition, direct shear tests, loading-unloading tests, modified Proctor and CBR tests are performed on the two soils and their mixtures with different scrap tire rubber (10, 20, 25 and 50%. The results show that liquid limits and plastic indexes decrease with the scrap tire rubber content and that the decrease is more significant for soil with high plasticity. Cohesion also decreases with scrap tire rubber content when the internal friction angle is vacillating. Compression and recompression indexes increase gradually with the scrap tire rubber content and the variation for compression index is more significant for the two soils. Compaction characteristics and CBR values decrease with scrap tire rubber content. The CBR values for W=3% are important compared to those with W=5% excepted for mixture with (75% tuff and 25% scrap tire rubber. The results show that the scrap tire rubber can be used as a reinforcement material for dredged soil, but with a content that should not highly affect the compressibility.

Urbanization and industrialization has resulted in a vast amount of artificial water containers in Taiwan, especially discarded automobile tires. 3.5 million automobile tires and several million motorcycle tires are discarded annually. The discarded tires contaminate the environment and also become a substantial number of breeding sites for the dengue vector mosquitoes. In order to establish a sound system for the recovery and disposal of discarded tires and to control dengue fever through source reduction, it has been emphasized that users must pay for their waste. It is necessary to recover and properly dispose of these discarded tired. The commercial firms which sell or manufacture tires are therefore advised to cooperate with the Environmental Protection Administration of the Executive Yuan, R.O.C. and follow the "Regulations of Recovery and Disposal of Discarded Tires". They are requested to establish foundations for the recovery of discarded tires. Those who are willing to join should prepay a deposit or related charge by the size of tire, which is imported or locally manufactured. The foundation utilizes the deposits for the recovery and disposal of discarded tires. From 1991 to 1993 the commercial tire firms had already achieved the 80% recovery rates declared by the authorities concerned. Some of the tires, after having been recovered, were recycled in the original form and the rest were cut into small pieces for recycling after physical treatment. It should be mentioned that the Department of Environmental Protection of Kaohsiung City has collected 80 thousand discarded automobile tires to be used as ocean jetty.(ABSTRACT TRUNCATED AT 250 WORDS)

Mothers care for their infants' umbilical cord stump in various ways. Different cord care practices have been documented; some are beneficial while others are harmful. Who and what influence the cord care practiced by mothers have, however, not been fully explored particularly in the study locale. The objective of this study was to determine the factors that influence cord care practices among mothers in Benin City. The study subjects included 497 mothers who brought their babies to Well Baby/Immunization Clinic at the University of Benin Teaching Hospital (UBTH), Benin City, Edo State, between July and August 2009. A structured questionnaire served as an instrument to extract information on their biodata and possible determinants of cord care practices. Significantly older women (P=0.023), educated mothers (P=0.029), and those who had male babies (P=0.013) practiced beneficial cord stump care practices. Beneficial cord care practice increased with increasing maternal educational status. The best predictors of beneficial cord care practices are maternal level of education (P=0.029) and infant's sex (P=0.013). The use of harmful cord care practices was more common among mothers who delivered outside the Teaching hospitals. Most (71.2%) of the mothers were aware of hygienic/beneficial cord care. The choices of cord care methods eventually practiced by mothers were influenced mainly by the disposition of nurses (51.3%), participants' mothers (32.0%), and their mothers-in-law (5.8%). There was no significant relationship between cord care practice on one hand and maternal parity, tribe, and socioeconomic classes on the other. The need for female education is again emphasized. The current findings strongly justify the need for public enlightenment programs, using the mass media and health talks in health facilities, targeting not only women of reproductive age but also secondary audience like their mothers, mothers-in-law, nurses, and attendants at health facilities

Dynamics and Stability of Rolling Viscoelastic Tires

Potter, Trevor [Univ. of California, Berkeley, CA (United States)

2013-04-30

Current steady state rolling tire calculations often do not include treads because treads destroy the rotational symmetry of the tire. We describe two methodologies to compute time periodic solutions of a two-dimensional viscoelastic tire with treads: solving a minimization problem and solving a system of equations. We also expand on work by Oden and Lin on free spinning rolling elastic tires in which they disovered a hierachy of N-peak steady state standing wave solutions. In addition to discovering a two-dimensional hierarchy of standing wave solutions that includes their N-peak hiearchy, we consider the eects of viscoelasticity on the standing wave solutions. Finally, a commonplace model of viscoelasticity used in our numerical experiments led to non-physical elastic energy growth for large tire speeds. We show that a viscoelastic model of Govindjee and Reese remedies the problem.

In this investigation, palm empty fruit bunch (EFB) and almond shell (AS) were implemented as two natural catalysts rich in alkali metals, especially potassium, to enhance the reactivity of tire-char through co-gasification process. Co-gasification experiments were conducted at several blending ratios using isothermal Thermogravimetric analysis (TGA) under CO2. The pronounced effect of inherent alkali content of biomass-chars on promoting the reactivity of tire-char was proven when acid-treated biomass-chars did not exert any catalytic effect on improving the reactivity of tire-char in co-gasification experiments. In kinetic studies of the co-gasified samples in chemically-controlled regime, modified random pore model (M-RPM) was adopted to describe the reactive behavior of the tire-char/biomass-char blends. By virtue of the catalytic effect of biomass, the activation energy for tire-char gasification was lowered from 250 kJ/mol in pure form 203 to 187 kJ/mol for AS-char and EFB-char co-gasified samples, respectively.

Tires are a key sub-system of vehicles that have a big responsibility for comfort, fuel consumption and traffic safety. However, current tires are just passive rubber elements which do not contribute actively to improve the driving experience or vehicle safety. The lack of information from the tire during driving gives cause for developing an intelligent tire. Therefore, the aim of the intelligent tire is to monitor tire working conditions in real-time, providing useful information to other systems and becoming an active system. In this paper, tire tread deformation is measured to provide a strong experimental base with different experiments and test results by means of a tire fitted with sensors. Tests under different working conditions such as vertical load or slip angle have been carried out with an indoor tire test rig. The experimental data analysis shows the strong relation that exists between lateral force and the maximum tensile and compressive strain peaks when the tire is not working at the limit of grip. In the last section, an estimation system from experimental data has been developed and implemented in Simulink to show the potential of strain sensors for developing intelligent tire systems, obtaining as major results a signal to detect tire's loss of grip and estimations of the lateral friction coefficient.

A lot of challenges face the current efforts at reducing Mother to Child transmission of HIV infection (MTCT) in Sub Saharan Africa due to limited access to Highly active antiretroviral therapy (HAART) and breast feeding practices. A regular review of progress is necessary in order to identify areas of need. This is a one year prospective descriptive study of seven hundred and twenty six mother-infant pairs managed in the PMTCT programme in Nnamdi Azikiwe University Teaching Hospital, Nnewi Southeast Nigeria. The babies HIV status was tested with PCR for HIV DNA while the mothers provided information on infant feeding pattern and the use of antiretroviral (ARV) drugs including prophylaxis for the baby. Information was augmented from the antenatal records. The transmission rate was 2.8% for mothers, who were on HAART, did not breastfeed and whose babies received ARV prophylactic therapy. But for mothers who did not receive HAART, did breastfeed and whose babies did not received ARV prophylactic therapy, the transmission rate was 37.5%. When both the mother and child received ARV drugs, the transmission rate was significantly lower in those who did not breastfeed (2.8%) than in those who breastfed (12.5%)(P < 0.001). When both the mother and child did not receive ARV drugs, the transmission rate significantly lower in those who did not breastfeed (21.1%)than in those who breastfed (37.5%) (P < 0.02). The use of HAART in PMTCT programme in the under resourced areas can achieve similar success rates to that in the industrialized countries. Breastfeeding reduces the efficacy achieved by the use of ARV drugs. Provision of wider access to HAART as well as adequate counselling and support for safer infant feeding practices is recommended.

In 1999, two leading Australian academics challenged Australian universities to lead moves to better manage employees' maternity and breastfeeding needs, and 'bring babies and breasts into workplaces'. This paper addresses the question of how universities cope with the need for women to breastfeed, by exploring barriers facing women who combine breastfeeding and paid work at the Australian National University (ANU). Data were collected through online surveys in 2013 using mixed method, case study design, nested within a larger national study. Participants were 64 working mothers of children aged 0-2 years from the ANU community of employees and users of on-campus child care. Responses highlighted the ad hoc nature of support for breastfeeding at ANU. Lack of organisational support for breastfeeding resulted in adverse consequences for some ANU staff. These included high work-related stresses and premature cessation of breastfeeding among women who had intended to breastfeed their infants in line with health recommendations.

Full Text Available Abstract Background Some national guidelines recommend the use of water alone for napkin cleansing. Yet, there is a readiness, amongst many parents, to use baby wipes. Evidence from randomised controlled trials, of the effect of baby wipes on newborn skin integrity is lacking. We conducted a study to examine the hypothesis that the use of a specifically formulated cleansing wipe on the napkin area of newborn infants ( Methods A prospective, assessor-blinded, randomised controlled equivalence trial was conducted during 2010. Healthy, term babies (n = 280, recruited within 48 hours of birth, were randomly assigned to have their napkin area cleansed with an alcohol-free baby wipe (140 babies or cotton wool and water (140 babies. Primary outcome was change in hydration from within 48 hours of birth to 4 weeks post-birth. Secondary outcomes comprised changes in trans-epidermal water loss, skin surface pH and erythema, presence of microbial skin contaminants/irritants at 4 weeks and napkin dermatitis reported by midwife at 4 weeks and mother during the 4 weeks. Results Complete hydration data were obtained for 254 (90.7 % babies. Wipes were shown to be equivalent to water and cotton wool in terms of skin hydration (intention-to-treat analysis: wipes 65.4 (SD 12.4 vs. water 63.5 (14.2, p = 0.47, 95 % CI -2.5 to 4.2; per protocol analysis: wipes 64.6 (12.4 vs. water 63.6 (14.3, p = 0.53, 95 % CI -2.4 to 4.2. No significant differences were found in the secondary outcomes, except for maternal-reported napkin dermatitis, which was higher in the water group (p = 0.025 for complete responses. Conclusions Baby wipes had an equivalent effect on skin hydration when compared with cotton wool and water. We found no evidence of any adverse effects of using these wipes. These findings offer reassurance to parents who choose to use baby wipes and to health professionals who support their use. Trial registration Current Controlled

Since 1958, phototherapy has been used as a method to cure jaundice, which is still an important disease in newborn children. Supported by a phenomenological and qualitative approach, this study aims to investigate the mothers' perception of the phototherapy treatment their children are submitted to. Research subjects were ten mothers of newborns under phototherapy treatment at the Neonatological Hospitalization Unit of a public maternity in Fortaleza-CE, Brazil. Data were collected between May and July 2002. We used group meetings with the mothers as suggested by Carl Rogers. Discourse was organized into categories according to Bardin, which revealed themes that were analyzed in view of Paterson's and Zderad's humanistic nursing theory, as follows: mothers' knowledge on phototherapy and concerns about the treatment. We concluded that the analyzed mothers' major concern is related to the babies' vision.

This study aimed to assess the impact of the Baby-Friendly Hospital Initiative on WHO-defined breastfeeding indicators in Shaqlawa district in Kurdistan region of Iraq. A household survey was carried out on a purposive non-probability sample of 200 mothers with a child aged < 30 months. Mothers were interviewed using a structured form to determine demographic data and feeding practices of the most recent child. The rate of early initiation of breastfeeding was 38.1%, exclusive breastfeeding was 15.4% and continued breastfeeding was 61.0% and 39.5% at 1 and 2 years of age respectively. A significant relationship was found between delivery at the Baby- Friendly accredited hospital and early initiation of breastfeeding but not with exclusive or continued breastfeeding. While continued breastfeeding at 1 year and 2 year was good, early initiation and exclusive breastfeeding indicators were not at an acceptable level, which indicates an ineffective role for the Baby-Friendly Hospital Initiative.

Full Text Available The identification of optimal tire design parameters for satisfying different requirements, i.e. tire performance characteristics, plays an essential role in tire design. In order to improve tire performance characteristics, formulation and solving of multi-objective optimization problem must be performed. This paper presents a multi-objective optimization procedure for determination of optimal tire design parameters for simultaneous minimization of strain energy density at two distinctive zones inside the tire. It consists of four main stages: pre-analysis, design of experiment, mathematical modeling and multi-objective optimization. Advantage of the proposed procedure is reflected in the fact that multi-objective optimization is based on the Pareto concept, which enables design engineers to obtain a complete set of optimization solutions and choose a suitable tire design. Furthermore, modeling of the relationships between tire design parameters and objective functions based on multiple regression analysis minimizes computational and modeling effort. The adequacy of the proposed tire design multi-objective optimization procedure has been validated by performing experimental trials based on finite element method.

Optical strain measurement for fault detection in haul-truck tires

International Nuclear Information System (INIS)

Kotchon, A; Nobes, D S; Lipsett, M G

2012-01-01

Tire condition is integral to the safe operation of heavy machinery, such as ultra-class haul trucks. A new approach to haul truck tire monitoring is being investigated based on optical strain measurement, which has the advantage of providing quantitative information from sensors that do not contact the tire. A laboratory-scale apparatus has been constructed to monitor a tire as it is subjected to various loads and pressures. Digital image correlation is used to calculate the deformation in the tire. Using this method, damage resulting from a horizontal and vertical cut created on the tire surface could be detected. A three-dimensional surface reconstruction of the tire was created to assist in the characterization of more complex damage types such as wear and fatigue. In addition to providing information for a possible industrial scale damage detection system, this apparatus will also further the understanding of damage mechanisms in tires.

To evaluate the relationship between mothers and their developmentally normal infants in terms of maternal alexithymia, depression and anxiety, and marital satisfaction. Fifty children between 18 and 48 months of age, and their mothers, were referred consecutively to the Infant Mental Health Unit of Ankara University School of Medicine, Department of Child and Adolescent Psychiatry. The sociodemographic features of the families and the depressive symptoms, anxiety, marital satisfaction and alexithymia levels of the mothers were assessed. The relationships between children in normal developmental stages and their mothers were evaluated and rated using a structured clinical procedure. There was a negative correlation between the mothers' alexithymia scores and the quality of the mother-infant relationship (p Mothers with high alexithymia showed higher depression and lower relationship qualities than mothers with low alexithymia, according to the correlation analysis. When depression and anxiety were controlled, high alexithymia levels were predictive of a low, impaired mother-infant relationship. Since alexithymia is a trait-like variable which has a negative correlation with impairment in a mother-infant relationship, it must be investigated in the assessment of mothers' interactions with their babies.

Expressed breast milk as 'connection' and its influence on the construction of 'motherhood' for mothers of preterm infants: a qualitative study

Full Text Available Abstract Background Breast milk is considered the optimal nutrition for all newborn infants. While there is high initiation of lactation among mothers of preterm infants in Australia, there is a rapid decline of continued lactation. Furthermore, there is an inverse relationship between infant gestation and duration of lactation. To better understand the breastfeeding experience of parents of very low birth weight (VLBW preterm infants an interpretive phenomenological study was conducted. Methods This longitudinal study was conducted using an interpretive phenomenological approach. Data were collected from 17 parents through 45 individual interviews with both mothers and fathers, from birth to 12 months of age. This data was then transcribed verbatim and analysed using thematic analysis. Results The analysis identified six primary themes: the intention to breastfeed naturally; breast milk as connection; the maternal role of breast milk producer; breast milk as the object of attention; breastfeeding and parenting the hospitalised baby and the demise of breastfeeding. This paper reports on the theme of 'breast milk as connection'. Providing expressed breast milk offered one way the mothers could be physiologically and emotionally connected to their preterm infant while they were in the constant care of hospital staff. Indeed, breast milk was considered the only way the new mother could connect her body (or part there of to her preterm baby in hospital. This sense of connection however, comes at a cost. On the one hand, the breast milk offers a feeling of connection to the baby, but, on the other, this connection comes only after disconnection of the mother and baby and – through breast expression – mother and her milk. This ability of breast milk to connect mother and baby makes the expressed breast milk highly valued, and places unexpected pressure on the mother to produce milk as integral to her sense of motherhood. Conclusion The findings of

Exclusive breastfeeding has the potential to reduce infant and under-five mortality, but research shows the practice is not widespread in resource-poor settings of sub-Saharan Africa. We explored factors influencing the decision to exclusively breastfeed among HIV-positive mothers accessing interventions for prevention of mother-to-child transmission of HIV in selected sites of Zambia. This exploratory qualitative study was embedded in research conducted on: HIV and infant feeding; choices and decision-outcomes in the context of prevention of mother-to-child transmission among HIV-positive mothers in Zambia. Thirty HIV-positive mothers and six key informants were recruited from two health facilities providing mother-to-child HIV transmission prevention services. A semi-structured guide was used to conduct interviews, which were digitally recorded and simultaneously transcribed. Data coding and analysis was done with the support of QRS Nvivo 10 version software. Despite the known benefits of exclusive breastfeeding, gaps in understanding and potential for behaviour change remained. We found that information promoting exclusive breastfeeding may have been understood by mothers as instructions from the health care workers indicating how to feed their HIV-exposed babies rather than as an option for the mothers' own informed-decision. This understanding influenced a mother's perceptions of breast milk safety while on antiretroviral medicine, of the formula feeding option, and of the baby crying after breastfeeding. The meanings mothers attached to exclusive breastfeeding thus influenced their understanding of breast milk insufficiency, abrupt weaning and mixed feeding in the context of preventing mother-to-child transmission of HIV. In order to enhance feeding practices for HIV-exposed infants, our study suggests a broader health campaign supporting all mothers to exclusively breastfeed.

The objective of this article was to determine the impact of different bottles and teats for feeding babies with a cleft palate (with and without a cleft lip) on weight velocity, feeding behaviour, and maternal self-esteem. A mixed methods study incorporating the use of diaries to record feeding patterns of babies and levels of professional support received was used. Growth was assessed by converting weights into standard deviation scores and using the differences to express weight velocity over a six-week period. Visual analogue scales were used to assess mothers' perceptions of their children and themselves. The Edinburgh Postnatal Depression Score (EPDS) was used to identify maternal depression. The study demonstrated that the most significant effect on weight was determined by cleft type. Babies with isolated clefts of the hard and soft palate experienced greater feeding problems and suffered the biggest weight losses. This remained significant independently of the type of bottle/teat used. Poor weight gain was also associated with a mother's low perception of herself and her child, and her tendency towards depression. The study highlights the importance of the early assessment of babies' feeding skills and regular follow-up and support from trained and experienced nurse specialists.

Gueissaz, Line; Massonnet, Geneviève

2013-07-10

Tire traces can be observed on several crime scenes as vehicles are often used by criminals. The tread abrasion on the road, while braking or skidding, leads to the production of small rubber particles which can be collected for comparison purposes. This research focused on the statistical comparison of Py-GC/MS profiles of tire traces and tire treads. The optimisation of the analytical method was carried out using experimental designs. The aim was to determine the best pyrolysis parameters regarding the repeatability of the results. Thus, the pyrolysis factor effect could also be calculated. The pyrolysis temperature was found to be five time more important than time. Finally, a pyrolysis at 650°C during 15s was selected. Ten tires of different manufacturers and models were used for this study. Several samples were collected on each tire, and several replicates were carried out to study the variability within each tire (intravariability). More than eighty compounds were integrated for each analysis and the variability study showed that more than 75% presented a relative standard deviation (RSD) below 5% for the ten tires, thus supporting a low intravariability. The variability between the ten tires (intervariability) presented higher values and the ten most variant compounds had a RSD value above 13%, supporting their high potential of discrimination between the tires tested. Principal Component Analysis (PCA) was able to fully discriminate the ten tires with the help of the first three principal components. The ten tires were finally used to perform braking tests on a racetrack with a vehicle equipped with an anti-lock braking system. The resulting tire traces were adequately collected using sheets of white gelatine. As for tires, the intravariability for the traces was found to be lower than the intervariability. Clustering methods were carried out and the Ward's method based on the squared Euclidean distance was able to correctly group all of the tire traces

To examine levels of parenting stress in mothers of preterm and term infants when the children were 2 years old; to determine the trajectory of stress over three time periods and to examine the association of maternal and neonatal factors and developmental outcomes with parenting stress. It is a prospective longitudinal study to determine parenting stress in mothers of preterm and term infants with outcomes having been previously obtained at 4 and 12 months. At 2 years, 79 preterm mothers (96 babies) and 64 term mothers (77 babies) participated. The mothers completed the Parenting Stress Index-Short Form (PSI-SF), the Depression, Anxiety, Stress Scale (DASS) and the Child Behaviour Checklist (CBCL). The infants had a neurological examination and the Bayley-III scales were administered. The mean total PSI-SF at 2 years was significantly higher for the preterm group compared with the term group of mothers (p=0.007). There was a significant increase in the mean total PSI over time for the preterm mothers (pparenting stress and abnormal scores on the DASS (pparenting stress and maternal demographics, neonatal factors or Bayley-III results. Parenting stress in mothers of preterm infants continues to be high at 2 years having increased over time. Maternal mental health problems and infant behavioural issues contribute to the stress. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Nowadays preserving nature, recycling or reusing materials are good policies. Around ten million tires are put out by year in Brazil, and it is not known for how long they will remain in environment till their complete degradation. This research used tires to replace coal in ceramic processing. In this way it helps to protect environment, to reduce the consumption of mineral deposits and to save money. Results show that tire powder can replace coal to obtain ceramic material, using one percent of tire. Experiments were carried out using TA instruments SDT 2960, in air or nitrogen atmospheres, at heating rate of 10 C/min., flow 120 ml/min. TG/DTA curves of tire and coal have exothermic events at close temperatures between 450-600 C. At range of temperatures clay have endothermic events. (orig.)

Related to the ionizing radiation exposure, the breast feed babies can be classified as individuals occupational y exposed and public individuals existing dose limits, and nonexisting limits. breast feeds are always considered as public individuals, independently of the category which women are classified. The contamination can occur by ingestion of mother warm milk on the cases of accidents involving mothers occupational y exposed, intake of radionuclides by inhalation, or ingestion, or when the mother are submitted to diagnostic procedures or therapeutics with radiopharmaceuticals, that can reach high concentrations in the milk which can cause significant absorbed doses for the children organs. Besides the internal dose, the close contact between the mother and the baby results in external doses. In Brazil, round 7 % of the diagnostic procedures use 131 I or 123 I, and 84 % are carry out by women. For 131 I, 67 Ga and 201 Tl, it is necessary the definitive interruption of the breast feeding. This work proposes a study on the risk of children and babies breast feed in the country. A questionnaire was developed to be applied to interviews with doctors and nurses on public and private nuclear medicine services, for the evaluation of the procedures used with young women. After that, will be developed a brochure for multidisciplinary teams, presenting the basic concepts on internal dosimetry of the children and babies, allowing the precise prediction of interruption time of the maternal breast feed and, when applicable, the alternative methods for that period

Full Text Available Tire rolling resistance has a major impact on vehicle fuel consumption. Rolling resistance is the loss of energy due to the interaction between the tire and the pavement surface. This interaction is a complicated combination of stresses and strains which depend on both tire and pavement related factors. These include vehicle speed, vehicle weight, tire material and type, road camber, tire inflation pressure, pavement surfacing texture etc. In this paper the relationship between pavement surface texture depth and tire/surfacing contact stress and area is investigated. Texture depth and tire/surfacing contact stress were measured for a range of tire inflation pressures on five different pavement surfaces. In the analysis the relationship between texture and the generated contact stresses as well as the contact stress between the surfacing and base layer are presented and discussed, and the anticipated effect of these relationships on the rolling resistance of vehicles on the surfacings, and subsequent vehicle fuel economy discussed.

The paper constructed engineering vehicle refurbished tire computer geometry model, mechanics model, contact model, finite element analysis model, did simulation study on load-deformation property of engineering vehicle refurbished tire by comparing with that of the new and the same type tire, got load-deformation of engineering vehicle refurbished tire under the working condition of static state and ground contact. The analysis result shows that change rules of radial-direction deformation and side-direction deformation of engineering vehicle refurbished tire are close to that of the new tire, radial-direction and side-direction deformation value is a little less than that of the new tire. When air inflation pressure was certain, radial-direction deformation linear rule of engineer vehicle refurbished tire would increase with load adding, however, side-direction deformation showed linear change rule, when air inflation pressure was low; and it would show increase of non-linear change rule, when air inflation pressure was very high.

The objective of this project was to design, develop, and demonstrate fuel efficient and safety regulation compliant tire filler and barrier coating technologies that will improve overall fuel efficiency by at least 2%. The program developed and validated two complementary approaches to improving fuel efficiency through tire improvements. The first technology was a modified silica-based product that is 15% lower in cost and/or enables a 10% improvement in tread wear while maintaining the already demonstrated minimum of 2% improvement in average fuel efficiency. The second technology was a barrier coating with reduced oxygen transmission rate compared to the state-of-the-art halobutyl rubber inner liners that will provide extended placarded tire pressure retention at significantly reduced material usage. A lower-permeance, thinner inner liner coating which retains tire pressure was expected to deliver the additional 2% reduction in fleet fuel consumption. From the 2006 Transportation Research Board Report1, a 10 percent reduction in rolling resistance can reduce consumer fuel expenditures by 1 to 2 percent for typical vehicles. This savings is equivalent to 6 to 12 gallons per year. A 1 psi drop in inflation pressure increases the tire's rolling resistance by about 1.4 percent.

Niskanen, Arto; Tuononen, Ari J

2015-08-05

Direct tire-road contact friction estimation is essential for future autonomous cars and active safety systems. Friction estimation methods have been proposed earlier for driving conditions in the presence of a slip angle or slip ratio. However, the estimation of the friction from a freely-rolling tire is still an unsolved topic. Knowing the existing friction potential would be beneficial since vehicle control systems could be adjusted before any remarkable tire force has been produced. Since accelerometers are well-known and robust, and thus a promising sensor type for intelligent tires, this study uses three three-axis IEPE accelerometers on the inner liner of a tire to detect friction potential indicators on two equally smooth surfaces with different friction levels. The equal roughness was chosen for both surfaces in order to study the friction phenomena by neglecting the effect of surface texture on vibrations. The acceleration data before the contact is used to differentiate the two friction levels between the tire and the road. In addition, the contact lengths from the three accelerometers are used to validate the acceleration data. A method to differentiate the friction levels on the basis of the acceleration signal is also introduced.

Ontario tire recycling and economic development (OnTRED) plan : a market approach to eliminating tire stockpiles and promoting recycled rubber product manufacturing in Ontario

Energy Technology Data Exchange (ETDEWEB)

NONE

2005-05-15

Details of the Ontario Tire Recycling and Economic Development (OnTRED) plan were presented. The plan was developed to address deficiencies in the Ontario Tire Stewardship's (OTS) Scrap Tire Diversion Program plan. The OTS promotes the burning of scrap tires contrary to the Waste Diversion Act, and transfers the financial responsibility for scrap tire management from manufacturers to retailers. The OnTRED plan will attempt to improve the current 87 per cent recovery rate for passenger scrap tires in Ontario, and prevent the formation of any new tire stockpiles. The aim of the OnTRED plan is to ensure reuse and recycling consistent with provisions in the Waste Diversion Act and enhance the existing workings of the tire and scrap tire market through the promotion of reuse and recycling. In addition, the plan aims to minimize administration and compliance costs. A program summary of the OnTRED plan was presented, as well as details of market development plans and buy-recycled rebates. Issues concerning collector registration and transaction tracking were presented, as well as details of brand-owner and first importer pay-in models. Stakeholder roles and responsibilities were reviewed. A budget scenario was presented, as well as a rebate and diversion scenario. It was concluded that Ontario's 87 per cent scrap tire diversion rate can be improved through a focus on patterns of reuse and recycling. 3 tabs., 7 figs.

An evaluation of string theory for the prediction of dynamic tire properties using scale model aircraft tires

Science.gov (United States)

Clark, S. K.; Dodge, R. N.; Nybakken, G. H.

1972-01-01

The string theory was evaluated for predicting lateral tire dynamic properties as obtained from scaled model tests. The experimental data and string theory predictions are in generally good agreement using lateral stiffness and relaxation length values obtained from the static or slowly rolling tire. The results indicate that lateral forces and self-aligning torques are linearly proportional to tire lateral stiffness and to the amplitude of either steer or lateral displacement. In addition, the results show that the ratio of input excitation frequency to road speed is the proper independent variable by which frequency should be measured.

A molecular dynamics (MD simulation on tire-aggregate friction

Directory of Open Access Journals (Sweden)

Fengyan Sun

2017-07-01

Full Text Available The friction between tire and road surface is fundamentally depending on the molecular forces. In this paper, the nanoscale 3D contact model is employed to investigate the tire-aggregate friction mechanism. The tire and aggregate micro-structure are both constructed to evaluate the microscopic performance of tire-aggregate friction influence. Simulation results show for a high velocity, the energy dissipation of sliding on crystal structure is small, which results in a small friction coefficient; temperature will have influences on the friction coefficient, and with the increasing of velocity, the effect will gradually reduce. Keywords: Tire, Aggregate, Friction coefficient, Microscopic mechanism, MD simulation

Born Too Soon: Care for the preterm baby

Science.gov (United States)

2013-01-01

As part of a supplement entitled "Born Too Soon", this paper focuses on care of the preterm newborn. An estimated 15 million babies are born preterm, and the survival gap between those born in high and low income countries is widening, with one million deaths a year due to direct complications of preterm birth, and around one million more where preterm birth is a risk factor, especially amongst those who are also growth restricted. Most premature babies (>80%) are between 32 and 37 weeks of gestation, and many die needlessly for lack of simple care. We outline a series of packages of care that build on essential care for every newborn comprising support for immediate and exclusive breastfeeding, thermal care, and hygienic cord and skin care. For babies who do not breathe at birth, rapid neonatal resuscitation is crucial. Extra care for small babies, including Kangaroo Mother Care, and feeding support, can halve mortality in babies weighing Neonatal intensive care units in high income settings are de-intensifying care, for example increasing use of continuous positive airway pressure (CPAP) and this makes comprehensive preterm care more transferable. For health systems in low and middle income settings with increasing facility births, district hospitals are the key frontier for improving obstetric and neonatal care, and some large scale programmes now include specific newborn care strategies. However there are still around 50 million births outside facilities, hence home visits for mothers and newborns, as well as women's groups are crucial for reaching these families, often the poorest. A fundamental challenge is improving programmatic tracking data for coverage and quality, and measuring disability-free survival. The power of parent's voices has been important in high-income countries in bringing attention to preterm newborns, but is still missing from the most affected countries.

Selbes, Meric; Yilmaz, Ozge; Khan, Abdul A; Karanfil, Tanju

2015-11-01

One concern for recycle and reuse of scrap tires is the leaching of tire constituents (organic and inorganic) with time, and their subsequent potential harmful impacts in environment. The main objective of this study was to examine the leaching of dissolved organic carbon (DOC), dissolved nitrogen (DN), and selected inorganic constituents from scrap tires. Different sizes of tire chips and crumb rubber were exposed to leaching solutions with pH's ranging from 3.0 to 10.0 for 28days. The leaching of DOC and DN were found to be higher for smaller size tire chips; however, the leaching of inorganic constituents was independent of the size. In general, basic pH conditions increased the leaching of DOC and DN, whereas acidic pH conditions led to elevated concentrations of metals. Leaching was minimal around the neutral pH values for all the monitored parameters. Analysis of the leaching rates showed that components associated with the rubbery portion of the tires (DOC, DN, zinc, calcium, magnesium, etc.) exhibited an initial rapid followed by a slow release. On the other hand, a constant rate of leaching was observed for iron and manganese, which are attributed to the metal wires present inside the tires. Although the total amounts that leached varied, the observed leaching rates were similar for all tire chip sizes and leaching solutions. Operation under neutral pH conditions, use of larger size tire chips, prewashing of tires, and removal of metal wires prior to application will reduce the impact of tire recycle and reuse.

The in-plane deformation of a tire carcass: analysis and measurement

OpenAIRE

Xiong, Yi; Tuononen, Ari

2015-01-01

The deformation of parts of a tire is the direct result of tire–road interactions, and therefore is of great interest in tire sensor development. This case study focuses on the analysis of the deformation of the tire carcass and investigates its potential for the estimation of the in-plane tire force. The deformation of the tire carcass due to applied steady-state in-plane forces is first analyzed with the flexible ring model and then validated through optical tire sensor measurements. Couple...

Congenital malformations among babies born following letrozole or clomiphene for infertility treatment.

2014-01-01

Clomiphene citrate (CC) is the first line drug for ovulation induction but because of its peripheral antiestrogenic effect, letrozole was introduced as the 2nd line drug. It lacks the peripheral antiestrogenic effect and is associated with similar or even higher pregnancy rates. Since letrozole is a drug for breast cancer, its use for the purpose of ovulation induction became controversial in the light of studies indicating an increased incidence of congenital malformations. To evaluate and compare the incidence of congenital malformations among offsprings of infertile couples who conceived naturally or with clomiphene citrate or letrozole treatment. A retrospective cohort study done at a tertiary infertility centre. A total of 623 children born to infertile women who conceived naturally or following clomiphene citrate or letrozole treatment were included in this study. Subjects were sorted out from medical files of both mother and newborn and follow up study was done based on the information provided by parents through telephonic conversations. Babies with suspected anomaly were called and examined by specialists for the presence of major and minor congenital malformations. Other outcomes like multiple pregnancy rate and birth weight were also studied. Overall, congenital malformations, chromosomal abnormalities were found in 5 out of 171 (2.9%) babies in natural conception group and 5 out of 201 babies in the letrozole group (2.5%) and in 10 of 251 babies in the CC group (3.9%). There was no significant difference in the overall rate of congenital malformations among children born to mothers who conceived naturally or after letrozole or CC treatment. Congenital malformations have been found to be comparable following natural conception, letrozole and clomiphene citrate. Thus, the undue fear against letrozole may be uncalled for.

Malmivuo, Mikko; Luoma, Juha; Porthin, Markus

2017-07-04

The aim of the study was to compare the safety effects of studded and unstudded winter tires based on fatal road accidents. The data included 958 road accidents involving a passenger car or van that occurred in Finland from November to March between 1997 and 2012. Comparing the proportions of winter tire type in accidents and in general traffic showed that the overall effect of tire type on the number of accidents was not significant, although studded tires reduced fatal accidents by 10-15%. Compared to unstudded tires, studded tires reduced accidents significantly only on bald ice in 2005-2012. Drivers using unstudded tires were more experienced and their profession was more frequently related to driving. In addition, the vehicle age was lower for vehicles with unstudded tires. On the other hand, the state of repair was less pertinent for unstudded than for studded tires. These confounding factors offset their effects to some degree. The risk of fatal road accidents in winter between studded and unstudded tires does not differ significantly. However, the accident risk has recently been substantially higher on bald ice for unstudded than for studded tires. The magnitude of this risk difference is difficult to determine without specific information on exposure by road surface.

2016-02-01

This study investigated the quality of mother-infant interaction and maternal ability to recognise adult affect in three study groups consisting of mothers with a diagnosis of schizophrenia, mothers with depression and healthy controls. Sixty-four mothers were recruited from a Mother and Baby Unit and local children's centres. A 5-min mother-infant interaction was coded on a number of caregiving variables. Affect recognition and discrimination abilities were tested via a series of computerised tasks. Group differences were found both in measures of affect recognition and in the mother-infant interaction. Mothers with schizophrenia showed consistent impairments across most of the parenting measures and all measures of affect recognition and discrimination. Mothers with depression fell between the mothers with schizophrenia and healthy controls on most measures. However, depressed women's parenting was not significantly poorer than controls on any of the measures, and only showed trends for differences with mothers with schizophrenia on a few measures. Regression analyses found impairments in affect recognition and a diagnosis of schizophrenia to predict the occurrence of odd or unusual speech in the mother-infant interaction. Results add to the growing body of knowledge on the mother-infant interaction in mothers with schizophrenia and mothers with depression compared to healthy controls, suggesting a need for parenting interventions aimed at mothers with these conditions. While affect recognition impairments were not found to fully explain differences in parenting among women with schizophrenia, further research is needed to understand the psychopathology of parenting disturbances within this clinical group.

Suncor Energy is the first company in Canada to use a new technology designed uniquely for tire recycling at oil sand facilities. The technology is owned by CuttingEdge Tire Recycling, a partnership between Denesoline Environmental Limited Partnership and Beaver Environmental Rubber Technologies Limited. Suncor has supported the development of this Aboriginal-owned and operated business by offering land, electricity, diesel fuel and stockpiles of used truck tires from its oil sand mining activities. These tires are the largest off-road tires in the world. In this new technology, tires that are worn-out through oil sand mining are shredded in a portable shredder before being recycled for subsequent use by the Alberta Recycling Management Association. 1 fig.

The status of chronic and occult HBV infection (OBI) in neonatal hepatitis B vaccine and immunoglobulin (HBIG) vaccinated infants born to HBsAg+ mothers was investigated at a major hospital in China. Seventy-seven and 15 blood samples were collected in first or second follow-up detection from the vaccinated babies aged 3-36 months born to 43 HBsAg+ or plus 25 HBeAg+ mothers. HBV infection was analyzed between the paired baby and mother by serology and DNA analysis. Among 77 children born to 68 HBsAg+ mothers, 3.9% (3/77) were HBsAg+, and 36.4% (28/77) were HBV DNA+/HBsAg- (OBIs) by a single PCR, respectively. Thirteen of 28 HBV DNA+/HBsAg- samples were conformed by two PCRs or S sequence, which accounted for 16.9% (13/77) of children. Three HBsAg+ and six OBIs were genotyped in consistent with their mother's HBV strains. Of 77 babies' blood samples, anti-HBs reactivity varied slightly according to age groups, while passively transmitted anti-HBc reactivity declined from 100% high reactivity at age 3-5 months to mostly negative at age ≥12 months. Babies with apparent OBI had higher levels of anti-HBc and lower levels of anti-HBs than those without OBI but all eight OBI babies with second follow-up samples became HBV DNA negative beyond 1 year of age. The vaccinated infants born to HBsAg+ mothers presented the low rate of HBsAg occurrence as vaccination failure and high frequency of viral persistence in the form of transient OBIs since no evidence of active HBV infection occurred beyond 1 year of age. © 2017 Wiley Periodicals, Inc.

The music of containment: Addressing the participants in mother-infant psychoanalytic treatment.

Science.gov (United States)

Salomonsson, Björn

2011-11-01

The author discusses the psychoanalyst's approach in mother-infant treatments. Emphasis is given to the infant as an important, though often neglected, addressee. A clinical example is used in which a telephone call during a prior session triggered fretting in a 3-month-old girl and distress in her mother. It is suggested that in the session, nonverbal levels of the interventions reached the girl and contained her, and that this containment worked along similar lines as the communicative musicality between mother and baby. In the discussion, the psychoanalytic concept of containment (Bion, 1962) is linked with the concept of communicative musicality (Trevarthen & Aitken, 2001). The mother's need for containment also is emphasized, and the therapist must be on alert when it is essential to focus on either participant in the therapy room. This choice is guided both by explicit deliberations and by the unconscious countertransference. However, the therapist's wish to grasp the countertransference is countered by his or her unwillingness of being reminded of feelings of infantile helplessness. Similarly, when the mother's conscious and unconscious messages diverge, the baby's ability to receive her caretaking is compromised. In the article's clinical case, this happened when the mother tried to soothe her daughter while being preoccupied with anger at the therapist to an extent to which she was not fully aware.

Polycyclic aromatic hydrocarbons, elemental and organic carbon emissions from tire-wear.

Science.gov (United States)

Aatmeeyata; Sharma, Mukesh

2010-09-15

Tire-wear is an important source of PAHs, elemental carbon (EC) and organic carbon (OC). The emissions of these pollutants have been studied in an experimental set-up, simulating a realistic road-tire interaction (summer tire-concrete road). The large particle non-exhaust emissions (LPNE; diameter greater than 10 microm) have been evaluated over 14,500 km run of the tire. An increasing linear trend with cumulative km run was observed for emissions of PAHs and carbon. Amongst PAHs in LPNE, pyrene has been observed to be the highest (30+/-4 mg kg(-1)) followed by benzo[ghi]perylene (17+/-2 mg kg(-1)). Different fractions of EC-OC for tire-wear have been analyzed, and unlike exhaust emissions, EC1 was observed to be 99% of EC whereas more than 70% of the OC was the high temperature carbon (OC3 and OC4). The overall emission factors (mass tire(-1) km(-1)) for PAHs, EC and OC from tire-wear are 378 ng tire(-1) km(-1), 1.46 mg tire(-1) km(-1) and 2.37 mg tire(-1) km(-1) for small cars.

Perceptions of low-income African-American mothers about excessive gestational weight gain.

Science.gov (United States)

Herring, Sharon J; Henry, Tasmia Q; Klotz, Alicia A; Foster, Gary D; Whitaker, Robert C

2012-12-01

A rising number of low-income African-American mothers gain more weight in pregnancy than is recommended, placing them at risk for poor maternal and fetal health outcomes. Little is known about the perceptions of mothers in this population that may influence excessive gestational weight gain. In 2010-2011, we conducted 4 focus groups with 31 low-income, pregnant African-Americans in Philadelphia. Two readers independently coded the focus group transcripts to identify recurrent themes. We identified 9 themes around perceptions that encouraged or discouraged high gestational weight gain. Mothers attributed high weight gain to eating more in pregnancy, which was the result of being hungrier and the belief that consuming more calories while pregnant was essential for babies' health. Family members, especially participants own mothers, strongly reinforced the need to "eat for two" to make a healthy baby. Mothers and their families recognized the link between poor fetal outcomes and low weight gains but not higher gains, and thus, most had a greater pre-occupation with too little food intake and weight gain rather than too much. Having physical symptoms from overeating and weight retention after previous pregnancies were factors that discouraged higher gains. Overall, low-income African-American mothers had more perceptions encouraging high gestational weight gain than discouraging it. Interventions to prevent excessive weight gain need to be sensitive to these perceptions. Messages that link guideline recommended weight gain to optimal infant outcomes and mothers' physical symptoms may be most effective for weight control.

The objective of this paper is a study of the potential of laser induced breakdown spectroscopy (LIBS) for detection of tire tread particles. Tire tread particles may represent pollutants; simultaneously, it is potentially possible to exploit detection of tire tread particles for identification of optically imperceptible braking tracks at locations of road accidents. The paper describes the general composition of tire treads and selection of an element suitable for detection using the LIBS method. Subsequently, the applicable spectral line is selected considering interferences with lines of elements that might be present together with the detected particles, and optimization of measurement parameters such as incident laser energy, gate delay and gate width is performed. In order to eliminate the matrix effect, measurements were performed using 4 types of tires manufactured by 3 different producers. An adhesive tape was used as a sample carrier. The most suitable adhesive tape was selected from 5 commonly available tapes, on the basis of their respective LIBS spectra. Calibration standards, i.e. an adhesive tape with different area content of tire tread particles, were prepared for the selected tire. A calibration line was created on the basis of the aforementioned calibration standards. The linear section of this line was used for determination of the detection limit value applicable to the selected tire. Considering the insignificant influence of matrix of various types of tires, it is possible to make a simple recalculation of the detection limit value on the basis of zinc content in a specific tire. - Highlights: • LIBS experimental measurement parameters for tire tread particles were optimize. • Calibration curve was prepared. • Limit of detection was determined.

The objective of this paper is a study of the potential of laser induced breakdown spectroscopy (LIBS) for detection of tire tread particles. Tire tread particles may represent pollutants; simultaneously, it is potentially possible to exploit detection of tire tread particles for identification of optically imperceptible braking tracks at locations of road accidents. The paper describes the general composition of tire treads and selection of an element suitable for detection using the LIBS method. Subsequently, the applicable spectral line is selected considering interferences with lines of elements that might be present together with the detected particles, and optimization of measurement parameters such as incident laser energy, gate delay and gate width is performed. In order to eliminate the matrix effect, measurements were performed using 4 types of tires manufactured by 3 different producers. An adhesive tape was used as a sample carrier. The most suitable adhesive tape was selected from 5 commonly available tapes, on the basis of their respective LIBS spectra. Calibration standards, i.e. an adhesive tape with different area content of tire tread particles, were prepared for the selected tire. A calibration line was created on the basis of the aforementioned calibration standards. The linear section of this line was used for determination of the detection limit value applicable to the selected tire. Considering the insignificant influence of matrix of various types of tires, it is possible to make a simple recalculation of the detection limit value on the basis of zinc content in a specific tire. - Highlights: • LIBS experimental measurement parameters for tire tread particles were optimize. • Calibration curve was prepared. • Limit of detection was determined

When disaster strikes -- caring for mothers and babies. Special feature -- mothers as refugees.

Science.gov (United States)

1997-01-01

In many countries, women are poorly nourished and have a high rate of reproductive morbidity. However, during war and other disaster situations, women and children become even more vulnerable. Most of the world's refugees and internally displaced people are women and children. Many women refugees are malnourished and during the emergency and exodus phases, many are starving. Severe malnutrition in a pregnant woman causes fetal malnutrition. Infants born to a malnourished mother are of low birth weight and will grow up malnourished if they stay in the same deprived environment as their mothers. Households headed by women tend to obtain the least food and the children of such households tend to be poorly nourished. Many of the problems and obstacles women face during peacetime and non-emergency situations are simply exacerbated during disasters and war. It may not be possible to head off disasters which result in massive social upheaval, but preparations can nonetheless be made to mollify conditions once disaster hits. Responsible organizations and agencies should research the situation and plan for the worst. This paper discusses how women lose social and economic power during periods of armed conflict, the often lack of even basic reproductive health care during armed conflict and emergencies, coping in an emergency, and living in a refugee camp.

2014-11-01

The aim of this study was to investigate the development of mother-infant interaction patterns from 3 to 12 months among three groups of mother-baby pairs recruited during pregnancy: one group from residential substance abuse treatment (n=28), a second group from psychiatric outpatient treatment (n=22), and a third group from well-baby clinics (n=30). The mother-infant interaction at 3 and 12 months was assessed by the Parent-Child Early Relational Assessment (PCERA), which consists of maternal, child and dyadic subscales (Clark, 2006). Linear mixed effects models were used to analyze group differences and the changes in mother-infant interaction from 3 to 12 months. At 3 months, pairwise comparisons showed that the group with psychiatric problems had significantly more difficulties in the mother-infant interaction than the two other groups. The group with substance abuse problems was not significantly different from the two other groups. At 12 months, the mother-infant pairs in the substance abuse group showed significantly more relational disturbances than the non-clinical pairs, as well as a poorer affective quality of interaction than the dyads in the group with psychiatric problems. Analysis of change from 3 to 12 months showed that difficulties in the interaction increased among the mother-baby pairs in the substance abuse group, while improvements were displayed in the two other groups. These results underline that mother-infant pairs at double risk due to maternal substance abuse and other non-optimal factors, are in need for long-term follow up in order to prevent the development of negative interactional patterns.

New developments in tire derived fuels (TDF)

Energy Technology Data Exchange (ETDEWEB)

Hawkins, G. [Portland Cement Association, Skokie, IL (United States)

2006-07-01

Portland cement is a mixture of finely ground raw materials that are processed in a rotary kiln heated to 1500 degrees C by various fuels. Cooled clinker from the kiln is ground into portland cement. This presentation provided an overview of the role that tire-derived fuels is now playing in cement manufacturing. Data on the extent of TDF use in cement manufacturing processes were presented, as well as the results of air emissions monitoring programs conducted to assess the environmental impacts of TDF. During the cement manufacturing process, shredded and chipped tires are blown into the kiln to provide fuel, while whole tires are placed in the midpoint of long dry or wet kilns. For preheater and precalciner kilns, whole tires are added to raw material entering the kiln. The kiln's controlled combustion environment ensures the complete destruction of scrap tires. Approximately 130 million scrap tires were recycled in Portland cement plants in 2003. Forty-four portland cement plants are currently using TDF in North America. The United States Department of Energy has estimated that TDF produces less carbon dioxide (CO{sub 2}) per unit of energy than coal. Monitoring programs at Portland cement plants have indicated that the use of TDF in place of coal has resulted in moderate reductions of nitrogen oxide (NO{sub x}) emissions, slightly lower sulfuric oxide (SO{sub 2}) emissions and moderate reductions in carbon monoxide (CO). Some plants have reported slight reductions in particulate matter (PM) emissions. It was concluded that the use of scrap tires as a fuel reduces a waste stream and contributes to energy and raw material requirements. Moreover, plant air emissions are either reduced or are not impacted by TDF use. refs., tabs., figs.

Maternal Coping with Baby Hospitalization at a Neonatal Intensive Care Unit

Fabiana Pinheiro Ramos

Full Text Available Abstract: Coping is defined by actions of self-regulation of emotions, cognitions, behaviors, and motivational orientation under stress. This study analyzed the maternal coping with hospitalization of premature and low birth weight infants at the Neonatal Intensive Care Unit (NICU, using the Motivational Theory of Coping. A questionnaire, a scale and an interview were applied to 25 mothers three times between birth and hospital discharge. The results showed that the mothers’ first visit to the NICU had strong emotional impact; longer hospitalization periods were linked to the decrease in Delegation coping strategies. There was more Support Seeking after the hospital discharge. Multiparous mothers and those who had a job appeared to be more vulnerable to stress. Predominantly adaptive coping responses were identified, even among two mothers whose babies had died, including Self-Reliance strategies, which were mediated by religious beliefs.

Optimal tread design for agricultural lug tires determined through failure analysis

Directory of Open Access Journals (Sweden)

Hyun Seok Song

2018-04-01

Full Text Available Agricultural lug tires, commonly used in tractors, must provide safe and stable support for the body of the vehicle and bear any additional load while effectively traversing rough, poor-quality ground surfaces. Many agricultural lug tires fail unexpectedly. In this study, we optimised and validated a tread design for agricultural lug tires intended to increase their durability using failure analysis. Specifically, we identified tire failure modes using indoor driving tests and failure mode effects analysis. Next, we developed a threedimensional tire model using the Ogden material model and finite element method. Using sensitivity analysis and response surface methodology, we optimised the tread design. Finally, we evaluated the durability of the new design using a tire prototype and drum test equipment. Results indicated that the optimised tread design decreased the tire tread stress by 16% and increased its time until cracking by 38% compared to conventional agricultural lug tires.

This study describes the multigenerational caregiving structure of infants born to young women, the prenatal predictors of caregiving structure, and the effects of caregiving structure on the health of young mothers and their infants 6 months postpartum. The sample consisted of 784 young mothers involved in a longitudinal study in two U.S. cities. Women were classified into eight caregiving structure groups based on the mother's report of herself as a caregiver and her selection of the baby's father and/or grandparents as caregivers. ANCOVA analyses identified predictors and 6 month postpartum outcomes of caregiving structure. Planned comparisons explored the relationships among caregiving structure groups. A majority of women reported caregiving structures other than herself and the father as caregivers (87.1%). Grandparents were indicated as caregivers by most women (62.2%). Postpartum caregiving groups differed on prenatal social support, self-esteem, attachment avoidance and anxiety, relationship status, and living with the baby's father. While mother's self esteem significantly predicted father involvement, there were no differences on predictors between when the mother and father were caregivers, versus when the mother and grandparents were caregivers. Differences existed between groups on mother and child outcomes, including parenting stress, distress, and child dysfunction. Women reported significantly less parenting stress, child dysfunction, and negative child emotions when she and the father were caregivers, versus when she and grandparents were caregivers. The family system and the intergenerational dynamics within a multigenerational caregiving structure are critical to the health and well-being of both mothers and their children.

Full Text Available We developed a method for pattern recognition of baby's emotions (discomfortable, hungry, or sleepy expressed in the baby's cries. A 32-dimensional fast Fourier transform is performed for sound form clips, detected by our reported method and used as training data. The power of the sound form judged as a silent region is subtracted from each power of the frequency element. The power of each frequency element after the subtraction is treated as one of the elements of the feature vector. We perform principal component analysis (PCA for the feature vectors of the training data. The emotion of the baby is recognized by the nearest neighbor criterion applied to the feature vector obtained from the test data of sound form clips after projecting the feature vector on the PCA space from the training data. Then, the emotion with the highest frequency among the recognition results for a sound form clip is judged as the emotion expressed by the baby's cry. We successfully applied the proposed method to pattern recognition of baby's emotions. The present investigation concerns the first stage of the development of a robotics baby caregiver that has the ability to detect baby's emotions. In this first stage, we have developed a method for detecting baby's emotions. We expect that the proposed method could be used in robots that can help take care of babies.

Research has found corporal punishment to have limited effectiveness in altering child behavior and the potential to produce psychological and cognitive damage. Pediatric professionals have advocated reducing, if not eliminating its use. Despite this, it remains a common parenting practice in the U.S. Using a three-group randomized design, this study explored whether embedding educational information about typical child development and effective parenting in baby books could alter new mothers’ attitudes about their use of corporal punishment. Low-income, ethnically diverse women (n = 167) were recruited during their third trimester of pregnancy and followed until their child was 18 months old. Findings from home-based data collection throughout this period suggest that educational baby books compared with non-educational baby books or no books can reduce new mothers’ support for the use of corporal punishment (respective effect sizes = .67 and .25) and that these effects are greater for African-American mothers (effect size = .75 and .57) and those with low levels of educational attainment (high school diploma, GED or less) (effect sizes = 0.78 and .49). Given their low cost and ease of implementation, baby books offer a promising way to change new mothers’ attitudes and potentially reduce the use of corporal punishment with infants and toddlers.

Grace, J T

1993-12-01

A postpartum measure, What Being the Parent of a New Baby is Like, was administered to explore the development of maternal role for mothers (N = 76) at 1, 3, 4 1/2, and 6 months postpartum. Individual differences were relatively stable across time and accounted for much more variance than time effects. Mean scores on the Centrality (of baby) and Help (with parenting tasks) subscales decreased over time, and Evaluation (satisfaction with role performance) and Lifechange subscale scores increased. Primiparas demonstrated the steepest mean increase in Evaluation scores over time. Mean Evaluation scores for first- (n = 29) and second-time mothers (n = 33) were similar, but mothers of three or more children (n = 14) had significantly higher scores. Parity was also related inversely to amount of life change, and maternal education was related inversely to Evaluation and Centrality scores. Demographic, subscale, and contextual variable interrelationships were generally consistent with maternal role adaptation theory. Findings also suggest that parity effects are more complex than a dichotomous primipara/multipara representation.

Dynamic tire pressure sensor for measuring ground vibration.

Wang, Qi; McDaniel, James Gregory; Wang, Ming L

2012-11-07

This work presents a convenient and non-contact acoustic sensing approach for measuring ground vibration. This approach, which uses an instantaneous dynamic tire pressure sensor (DTPS), possesses the capability to replace the accelerometer or directional microphone currently being used for inspecting pavement conditions. By measuring dynamic pressure changes inside the tire, ground vibration can be amplified and isolated from environmental noise. In this work, verifications of the DTPS concept of sensing inside the tire have been carried out. In addition, comparisons between a DTPS, ground-mounted accelerometer, and directional microphone are made. A data analysis algorithm has been developed and optimized to reconstruct ground acceleration from DTPS data. Numerical and experimental studies of this DTPS reveal a strong potential for measuring ground vibration caused by a moving vehicle. A calibration of transfer function between dynamic tire pressure change and ground acceleration may be needed for different tire system or for more accurate application.

A variety of tests was undertaken to determine the nature of heat generation associated with a pneumatic tire operating under various conditions. Tests were conducted to determine the magnitude and distribution of internally generated heat caused by hysteresis in the rubber and ply fabric in an automobile tire operating under conditions of load, pressure, and velocity representative of normal operating conditions. These included tests at various yaw angles and tests with braking applied. In other tests, temperature sensors were mounted on a road to measure the effect of a tire rolling over and an attempt was made to deduce the magnitude and nature of interfacial friction from the resulting information. In addition, tests were performed using the scratch plate technique to determine the nature of the motion between the tire and road. Finally, a model tire was tested on a roadwheel, the surface covering which could be changed, and an optical pyrometer was used to measure rubber surface temperatures.

2013-09-01

Poor diet quality is common among low-income, overweight, African-American mothers, placing them at high risk for adverse pregnancy outcomes. We sought to better understand the contextual factors that may influence low-income African-American mothers' diet quality during pregnancy. In 2011, we conducted semi-structured interviews with 21 overweight/obese, pregnant African Americans in Philadelphia, PA, all of whom received Medicaid and were eligible for the Special Supplemental Nutrition Program for Women, Infants, and Children. Two readers independently coded the interview transcripts to identify recurrent themes. We identified 10 themes around motivators and barriers to healthy eating in pregnancy. Mothers believed that consuming healthy foods, like fruits and vegetables, would lead to healthy babies and limit the physical discomforts of pregnancy. However, more often than not, mothers chose foods that were high in fats and sugars because of taste, cost, and convenience. In addition, mothers had several misconceptions about the definition of healthy (eg, "juice is good for baby"), which led to overconsumption. Many mothers feared they might "starve" their babies if they did not get enough to eat, promoting persistent snacking and larger portions. Living in multigenerational households and sharing resources also limited the mothers' control over food choices and made consuming healthy foods especially difficult. Despite the good intentions of low-income African-American mothers to improve diet quality during pregnancy, multiple factors worked together as barriers to healthy eating. Interventions that emphasize tasty and affordable healthy food substitutes, address misconceptions, and counsel mothers about true energy needs in pregnancy may improve low-income, African-American, overweight/obese mothers' diet quality.

2010-01-01

The first part of this paper presents the results of experimental estimation of the contact patch area depending on the normal wheel load and inflation pressure for different car tires. The data were obtained for test bench conditions on the basis of the visual processing of tread footprint. Further, the contact length in the cohesion area during wheel rolling for single points on the tire profile has been chosen as a benchmark criterion. This paper has analyzed the influence of the wheel normal load and tire inflation pressure on the contact length with small rolling velocities. The results of the investigations are given for winter and racing tires with different grades of wear.

To measure levels of parenting stress and postnatal depression in mothers of very preterm infants in comparison with mothers of infants born at term is the objective of this study. The study also aimed to explore factors associated with parenting stress in the mothers of the preterm infants. One hundred and five mothers who delivered 124 babies at ≤30 weeks gestation were enrolled together with 105 term mothers who delivered 120 babies. At one year of age (corrected for prematurity for the preterm cohort), the mothers completed the Parenting Stress Index Short Form (PSI), the Edinburgh Postnatal Depression Scale (EPDS) and the Short Temperament Scale for Toddlers. The infants had neurodevelopmental assessment. The preterm and term groups were compared. Questionnaires were completed by 101 of the preterm mothers and 98 of the term mothers. The mean PSI Total Stress score was significantly higher for the preterm mothers (70.28 vs 64.52, p = 0.022), with 19% of the preterm group and 9% of the term group having high scores (p = 0.038).There was no group difference on the EPDS or measures of temperament, with disability being greater in the preterm infants. For the preterm group, maternal depression and infant temperament were independent predictors of Total Stress scores on multivariate analysis. Parenting stress in mothers of preterm infants at one year of age is significantly greater than that found in mothers of term infants. For preterm mothers, symptoms of depression and infant temperament are independent risk factors for higher levels of parenting stress. Copyright © 2013 Elsevier Ltd. All rights reserved.

Indirect Tire Monitoring System - Machine Learning Approach

Svensson, O.; Thelin, S.; Byttner, S.; Fan, Y.

2017-10-01

The heavy vehicle industry has today no requirement to provide a tire pressure monitoring system by law. This has created issues surrounding unknown tire pressure and thread depth during active service. There is also no standardization for these kind of systems which means that different manufacturers and third party solutions work after their own principles and it can be hard to know what works for a given vehicle type. The objective is to create an indirect tire monitoring system that can generalize a method that detect both incorrect tire pressure and thread depth for different type of vehicles within a fleet without the need for additional physical sensors or vehicle specific parameters. The existing sensors that are connected communicate through CAN and are interpreted by the Drivec Bridge hardware that exist in the fleet. By using supervised machine learning a classifier was created for each axle where the main focus was the front axle which had the most issues. The classifier will classify the vehicles tires condition and will be implemented in Drivecs cloud service where it will receive its data. The resulting classifier is a random forest implemented in Python. The result from the front axle with a data set consisting of 9767 samples of buses with correct tire condition and 1909 samples of buses with incorrect tire condition it has an accuracy of 90.54% (0.96%). The data sets are created from 34 unique measurements from buses between January and May 2017. This classifier has been exported and is used inside a Node.js module created for Drivecs cloud service which is the result of the whole implementation. The developed solution is called Indirect Tire Monitoring System (ITMS) and is seen as a process. This process will predict bad classes in the cloud which will lead to warnings. The warnings are defined as incidents. They contain only the information needed and the bandwidth of the incidents are also controlled so incidents are created within an

Full Text Available O presente estudo teve por objetivo investigar a evolução do desenvolvimento motor e de linguagem em bebês com atraso de desenvolvimento a partir da perspectiva materna. Participaram do estudo seis mães de bebês com atraso de desenvolvimento. A pesquisa foi realizada numa instituição com programa de intervenção precoce e em ambiente domiciliar. Foram feitas entrevistas com as mães, por meio de um roteiro semiestruturado. O modo de compreensão das mães, tanto do processo de desenvolvimento motor, quanto linguístico dos filhos, indicou uma evolução no desenvolvimento dessas crianças. Uma das provas disso, foi a forma como essas mães se referiram ao desenvolvimento das crianças, antes destas ingressarem no programa de intervenção precoce e no momento atual. Conhecer e valorizar as percepções trazidas pelos cuidadores e particularmente pelas mães, implica em ampliar o entendimento dos seus saberes e práticas. Estes valores, por sua vez, podem ser utilizados no sentido de favorecer todo o processo de desenvolvimento infantil.The aim of the present study was to investigate the evolution of motor and language development in developmentally delayed babies from the mother's perspective. Six mothers of developmentally delayed babies participated in the study. This study was conducted in an institution that had an early intervention program and in the home environment. Interviews with the mothers were conducted using a semi-structured questionnaire. The way the mothers understood both their children's processes of motor and language development was indicative of an evolution in these children's development. The ways these mothers reported on the development of the children before they entered the early intervention program and at present is evidence to this effect. To know and to value the perception that caretakers have about their children has to do with broadening their understanding and practices. These values, in turn, can be

We aimed to investigate the role of peripheral blood mononuclear cell transportation from mother to baby in hepatitis B virus (HBV) intrauterine infection. Thirty HBsAg-positive pregnant women in the second trimester and their aborted fetuses were included in this study. Enzyme-linked-immunosorbent-assay was utilized to detect HBsAg in the peripheral blood of pregnant women and the femoral vein blood of their aborted fetuses. HBV-DNA in serum and peripheral blood mononuclear cells (PBMC) and GSTM1 alleles of pregnant women and their aborted fetuses were detected by nested polymerase chain reaction (PCR) and seminested PCR, respectively. We also examined the location of placenta HBsAg and HBcAb using immunohistochemical staining. The expression of placenta HBV-DNA was detected by in situ hybridization. For the 30 aborted fetuses, the HBV intrauterine infection rate was 43.33%. The HBV-positive rates of HBsAg in peripheral blood, serum, and PBMC were 10% (3/30), 23.33% (7/30), and 33.33% (10/30), respectively. Maternal-fetal PBMC transport was significantly positively correlated with fetal PBMC HBV-DNA (P = 0.004). Meanwhile, the rates of HBV infection gradually decreased from the maternal side to the fetus side of placenta (decidual cells > trophoblastic cells > villous mesenchymal cells > villous capillary endothelial cells). However, no significant correlation between placenta HBV infection and HBV intrauterine infection was observed (P = 0.410). HBV intrauterine infection was primarily due to peripheral blood mononuclear cell maternal-fetal transportation in the second trimester in pregnant women.

Full Text Available Introduction: Babies born before arrival at a health facility have a higher risk of neonatal death and their mothers a higher risk of maternal death compared with those born in-facility. The study explored the reasons for mothers giving birth before arrival (BBA at health facilities and their experiences of BBA. Methods: A qualitative research design was used. Individual and focus group interviews of BBA mothers and of nurses were undertaken at a community health centre and a district hospital in King Sabata Dalindyebo Local Municipality. Results: Reasons for BBA included a lack of transport, a lack of security at night that deterred mothers from travelling, precipitate labour, failure to identify true labour, and a lack of waiting areas at health facilities. Traditional and cultural beliefs favouring childbirth at homeand nurses’ negative attitudes during antenatal care and labour influenced mothers to go to health facilities when in advanced labour. Mothers were aware of possible complications associated with BBA. Conclusion: Socio-economic, individual, cultural and health system factors influence the occurrence of BBA. Relevant parties need to address these factors to ensure that all babies in the King Sabata Dalindyebo Local Municipality are delivered within designated health facilities.

Using Baby Books to Change New Mothers’ Attitudes About Corporal Punishment

OpenAIRE

Reich, Stephanie M.; Penner, Emily K.; Duncan, Greg J.; Auger, Anamarie

2012-01-01

Research has found corporal punishment to have limited effectiveness in altering child behavior and the potential to produce psychological and cognitive damage. Pediatric professionals have advocated reducing, if not eliminating its use. Despite this, it remains a common parenting practice in the U.S. Using a three-group randomized design, this study explored whether embedding educational information about typical child development and effective parenting in baby books could alter new mothers...

There are reports that the maternal diet during pregnancy may affect development of babies' eczema. We sought to investigate the association between the maternal diet during pregnancy and the risk of eczema in infancy in Japan. A birth cohort was set up at 2 hospitals in Chiba city. Dietary habits concerning fish, butter, margarine, yogurt and natto during pregnancy was obtained from mothers just after delivery. The intake frequencies of these foods were classified into four groups: 1) daily, 2) 2-3 times a week, 3) once a week and 4) once a month or less. Diagnosis of eczema at 6 months of age was made by the presence of an itchy rash that persisted more than two months. Valid data on 650 mother-baby pairs were obtained. No relationship between frequencies of the maternal intake of fish, margarine and yogurt during pregnancy and the onset rate of the babies' eczema were observed. For butter consumption, the incidence of babies' eczema was significantly higher in the group with daily intake than in those with an intake 2-3 times a week or less (p = 0.044). For natto, incidence of babies' eczema was significantly lower in the group with everyday intake than those eating it 2-3 times a week or less (p = 0.020). High frequency intake of natto during pregnancy possibly reduces the incidence of eczema in children at 6 months of age.

Breastfeeding promotion, protection, and support are one of the most cost-effective public health interventions to advance maternal and child health. The World Health Organization, the United Nations International Children's Emergency Fund, and numerous health organizations have recommended exclusive breastfeeding for the first 6 months of life, which is a key indicator of breastfeeding promotion programs worldwide. Despite the recommendations and various initiatives to promote breastfeeding, most women do not reach the exclusive breastfeeding target in both developed and developing countries. Such has been the case in the United Arab Emirates (UAE). Therefore, based on the decree for breastfeeding promotion, protection, and support by the ruler of the Emirate of Sharjah, UAE, H.H. Sheikh Doctor Sultan Al Qasimi, a multisectorial, multidirectional breastfeeding campaign--the Sharjah Baby-Friendly Campaign--was launched in March 2012 by H.E. Sheikha Bodour Al Qasimi, under her patronage. It consisted of four initiatives-namely, Baby-Friendly Health Facility, Mother-Friendly Workplace, Breastfeeding-Friendly Nursery, and Mother-Baby Friendly Public Place. Once an organization met the criteria for any of these initiatives, it was awarded the designation or accreditation of that initiative. The campaign initiatives worked through capacity building of healthcare workers, provided professional support and facilitation for the accreditation process, developed breastfeeding education content and resources, and organized and conducted breastfeeding promotion seminars in health facilities and community, as well as community outreach through social media and an innovative mobile mother' room. The positive impact of the campaign on breastfeeding promotion, protection, and support is evident by the increased exclusive breastfeeding rate at 6 months and decreased bottle feeding rates at both 4 and 6 months.

Final Scientific Report - "Improved Fuel Efficiency from Nanocomposite Tire Tread"

Energy Technology Data Exchange (ETDEWEB)

Dr. Andrew Myers

2005-12-30

Rolling resistance, a measure of the energy lost as a tire rotates while moving, is a significant source of power and fuel loss. Recently, low rolling resistant tires have been formulated by adding silica to tire tread. These "Green Tires" (so named from the environmental advantages of lower emissions and improved fuel economy) have seen some commercial success in Europe, where high fuel prices and performance drive tire selection. Unfortunately, the higher costs of the silica and a more complicated manufacturing process have prevented significant commercialization - and the resulting fuel savings - in the U.S. In this project, TDA Research, Inc. (TDA) prepared an inexpensive alternative to silica that leads to tire components with lower rolling resistance. These new tire composite materials were processed with traditional rubber processing equipment. We prepared specially designed nanoparticle additives, based on a high purity, inorganic mineral whose surface can be easily modified for compatibility with tire tread formulations. Our nanocomposites decreased energy losses to hysteresis, the loss of energy from the compression and relaxation of an elastic material, by nearly 20% compared to a blank SBR sample. We also demonstrated better performance than a leading silica product, with easier production of our final rubber nanocomposite.

Photocatalytic Desulfurization of Waste Tire Pyrolysis Oil

Directory of Open Access Journals (Sweden)

Napida Hinchiranan

2011-11-01

Full Text Available Waste tire pyrolysis oil has high potential to replace conventional fossil liquid fuels due to its high calorific heating value. However, the large amounts of sulfurous compounds in this oil hinders its application. Thus, the aim of this research was to investigate the possibility to apply the photo-assisted oxidation catalyzed by titanium dioxide (TiO2, Degussa P-25 to partially remove sulfurous compounds in the waste tire pyrolysis oil under milder reaction conditions without hydrogen consumption. A waste tire pyrolysis oil with 0.84% (w/w of sulfurous content containing suspended TiO2 was irradiated by using a high-pressure mercury lamp for 7 h. The oxidized sulfur compounds were then migrated into the solvent-extraction phase. A maximum % sulfur removal of 43.6% was achieved when 7 g/L of TiO2 was loaded into a 1/4 (v/v mixture of pyrolysis waste tire oil/acetonitrile at 50 °C in the presence of air. Chromatographic analysis confirmed that the photo-oxidized sulfurous compounds presented in the waste tire pyrolysis oil had higher polarity, which were readily dissolved and separated in distilled water. The properties of the photoxidized product were also reported and compared to those of crude oil.

The evolution of vehicle safety systems, from the earliest brakes to today's accident avoidance systems, has led vehicles to have very high passenger safety. Driving on ice, though, still happens to be one of the driving conditions of low safety. A multitude of factors were identified by various studies to contribute to the complex frictional mechanism at the tire-ice interface. The tire is only force transmitting element of the vehicle, to the surface. Thus it is very essential to have in de...

Distribution of sulphur into products from waste tire pyrolysis

International Nuclear Information System (INIS)

Susa, D.; Haydary, J.; Markos, J.

2012-01-01

Tire pyrolysis is getting growing attention as an effective waste tire disposal method in comparison to environmentally less friendly methods like dumping or incineration. But the scrap tire sulphur content can be a potential obstacle to scrap tire utilization as a fuel. In this paper the distribution of sulphur into tire pyrolysis yields, solid (char) and liquid (tar), was investigated. The pyrolysis experiments were carried out under different conditions to determine the partitioning of sulphur into pyrolysis products. The influence of different temperatures and reaction times was investigated in a laboratory flow reactor under nitrogen atmosphere. Solid and liquid residues were collected and analyzed by elemental analysis. The sulphur content in residual char and tar was determined using an elemental analyzer and the sulphur forms in tar were characterized by the X-ray photoelectron spectroscopy (XPS). (Authors)

Birth of a healthy baby from abdominal pregnancy, a rare event: A case report

Nahreen Akhtar

2016-07-01

Full Text Available Abdominal pregnancy is a rare form of ectopic pregnancy with very high morbidity and mortality for both the mother and the fetus. Diagnosis and management can pose some difficulties especially in low resource centres. High index of suspi­cious is vital in making prompt diagnosis in such situations. A young lady of 30 years presented with 2nd gravida at 31 wks pregnancy with pain in the whole abdomen having loose motion admitted in Dept of Obs and Gynae BSMMU. She was diagnosed as a case of 31 wks pregnancy with gastroenteritis. She was treated conservatively according to advice of gastroenterologist and was discharged after improvement. Patient was readmitted again with pervaginal watery discharge. Decision for cesarean section was taken because of transverse lie, fetal growth restriction with severe oligohydramnios. After opening the abdomen, abdominal pregnancy was diagnosed. Following delivery of the baby significant bleeding started which was secured with ligature. Placenta was kept in situ. Mother and baby were discharged healthy on fourteenth postoperative day.

Full Text Available Now improvement of technological design specification of trucks tires develops very much. In modern mechanical engineering polyamide and kapron cords for tires of line-haul trucks and buses are replaced with all-metal ones (AMC even more often. It was defined that at increase in AMC tires production their technical characteristics were investigated insufficiently. In this regard there were carried out bench tests to compare the main operational indicators of domestic (JSC Nizhnekamskshina production and foreign tires with an all-metal cord: 315/60R22.5 the NF-201 model with 315/60r22.5 the XZA2 ENERGY Michelin model (steering; 315/60R22.5 the NR-201 model with 315/60R22.5 the XDA2+ ENERGY Michelin model (drive; 315/80R22.5 the NF-201 model with 315/80R22.5 the 3D Michelin XZE X MultiWay model (steering; 315/80R22.5 the NR-201 model with 315/80R22.5 the 3D XDE X MultiWay model (drive. The laboratory researches were carried out for the purpose of an assessment of the universal, load, damping (hysteresis and other characteristics of tires with use of the universal functional SIB-1M test-bench. It was established that Michelin AMC tires of steering low-profile 315/60R22.5 XZA2 ENERGY models have the best indicators on power heterogeneity - 0.47-0.89 percent. The high-profile AMC tires of drive wheels 315/80R22.5 of the NR-201 model of JSC Nizhnekamskshina have the worst indicators. However, all the tested tires correspond to GOST 5513-97on this indicator. It was noted that Nizhnekamsk AMC tires of the size 315/60R22.5 are flush with AMC tires Michelin on set of operational indicators, except power heterogeneity, and last one of Michelin tires is lower than Nizhnekamsk ones by 2-3 times. It was suggested to conduct further researches on definition of optimum operational tires indicators because of an intensive use of KAMAZ trucks in agricultural production

Comparison between swinging and playing of white noise among colicky babies: A paired randomised controlled trial.

Science.gov (United States)

Sezici, Emel; Yigit, Deniz

2018-02-01

This study aimed to compare the effects of swinging and playing of white noise on the crying and sleeping durations of colicky babies. Infantile colic (IC) is one of the most common reasons for doctor visits among babies younger than 3 months. One of five babies older than 3 months also experiences IC. IC, unlike gastrointestinal problems, is regarded as an individual differentiation and maturation of the central nervous system. Providing a warm bath, breastfeeding, swinging and playing of white noise are nonpharmacological methods. The efficiency of these methods has been proven by various studies independently of one another. The study is a prospective, multicentre, paired randomised controlled trial. The study was conducted between April-December 2016. The study sample consisted of 40 1-month-old babies with gas pains who passed a hearing screening and their mothers. The total daily crying and sleeping durations of the babies were determined without any intervention on the first week. On the second week, 20 randomly selected babies (first group) were swung each time they cried, and on the third week, they were made to listen to white noise. The other 20 babies (second group) were made to listen to white noise on the second week and were swung on the third week. Swinging and playing of white noise were performed until the babies stopped crying. After every intervention, the total crying and sleeping durations of the babies were evaluated using a "Colicky Baby's Diary." Playing of white noise significantly decreased the daily crying durations (p white noise was found to be a more effective nonpharmacological method on crying and sleeping durations of colicky babies than swinging. Playing of white noise may be helpful for parents and healthcare personnel in reducing the gas pains of babies. © 2017 John Wiley & Sons Ltd.

The prediction of airborne and structure-borne noise potential for a tire

Science.gov (United States)

Sakamoto, Nicholas Y.

Tire/pavement interaction noise is a major component of both exterior pass-by noise and vehicle interior noise. The current testing methods for ranking tires from loud to quiet require expensive equipment, multiple tires, and/or long experimental set-up and run times. If a laboratory based off-vehicle test could be used to identify the airborne and structure-borne potential of a tire from its dynamic characteristics, a relative ranking of a large group of tires could be performed at relatively modest expense. This would provide a smaller sample set of tires for follow-up testing and thus save expense for automobile OEMs. The focus of this research was identifying key noise features from a tire/pavement experiment. These results were compared against a stationary tire test in which the natural response of the tire to a forced input was measured. Since speed was identified as having some effect on the noise, an input function was also developed to allow the tires to be ranked at an appropriate speed. A relative noise model was used on a second sample set of tires to verify if the ranking could be used against interior vehicle measurements. While overall level analysis of the specified spectrum had mixed success, important noise generating features were identified, and the methods used could be improved to develop a standard off-vehicle test to predict a tire's noise potential.

T.R.I.C.K.-Tire/Road Interaction Characterization & Knowledge - A tool for the evaluation of tire and vehicle performances in outdoor test sessions

Science.gov (United States)

Farroni, Flavio

2016-05-01

The most powerful engine, the most sophisticated aerodynamic devices or the most complex control systems will not improve vehicle performances if the forces exchanged with the road are not optimized by proper employment and knowledge of tires. The vehicle interface with the ground is constituted by the sum of small surfaces, wide about as one of our palms, in which tire/road interaction forces are exchanged. From this it is clear to see how the optimization of tire behavior represents a key-factor in the definition of the best setup of the whole vehicle. Nowadays, people and companies playing a role in automotive sector are looking for the optimal solution to model and understand tire's behavior both in experimental and simulation environments. The studies carried out and the tool developed herein demonstrate a new approach in tire characterization and in vehicle simulation procedures. This enables the reproduction of the dynamic response of a tire through the use of specific track sessions, carried out with the aim to employ the vehicle as a moving lab. The final product, named TRICK tool (Tire/Road Interaction Characterization and Knowledge), comprises of a vehicle model which processes experimental signals acquired from vehicle CAN bus and from sideslip angle estimation additional instrumentation. The output of the tool is several extra "virtual telemetry" channels, based on the time history of the acquired signals and containing force and slip estimations, useful to provide tire interaction characteristics. TRICK results can be integrated with the physical models developed by the Vehicle Dynamics UniNa research group, providing a multitude of working solutions and constituting an ideal instrument for the prediction and the simulation of the real tire dynamics.

2012-01-01

A scenario of an automotive accident caused by tire failure is given followed by a human factors analysis of the information available to consumers on tire aging. Consumers have not been told that the age of the tire is a safety concern. It is not easy to decode the date of manufacture on tires. More publicity and prominent warnings are needed to communicate the dangers of older tires. Also, better ways to present the date of manufacture so that consumers can more easily and accurately assess tire age are needed.

Breastfeeding provides optimal and complete nutrition for newborn babies. Although new mothers in Hong Kong are increasingly choosing to breastfeed their babies, rates of exclusive breastfeeding are low and duration remains short. The purpose of this study was to describe the breastfeeding and weaning practices of Hong Kong mothers over the infant's first year of life to determine the factors associated with early cessation. A cohort of 1417 mother-infant pairs was recruited from the obstetric units of four public hospitals in Hong Kong in the immediate post-partum period and followed prospectively for 12 months or until weaned. We used descriptive statistics to describe breastfeeding and weaning practices and multiple logistic regression to investigate the relationship between maternal characteristics and breastfeeding cessation. At 1 month, 3 months, 6 months and 12 months only 63%, 37.3%, 26.9%, and 12.5% of the infants respectively, were still receiving any breast milk; approximately one-half of breastfeeding mothers were exclusively breastfeeding. Younger mothers, those with a longer duration of residence in Hong Kong, and those returning to work postpartum were more likely to wean before 1 month. Mothers with higher education, previous breastfeeding experience, who were breastfed themselves and those who were planning to exclusively breastfeed and whose husbands preferred breastfeeding were more likely to continue breastfeeding beyond 1 month. The introduction of infant formula before 1 month and returning to work postpartum were predictive of weaning before 3 months. Breastfeeding promotion programs have been successful in achieving high rates of breastfeeding initiation but the focus must now shift to helping new mothers exclusively breastfeed and sustain breastfeeding for longer.

A longitudinal pre-pregnancy to post-delivery comparison of genetic and gestational surrogate and intended mothers: confidence and genealogy.

Science.gov (United States)

Van Den Akker, Olga B A

2005-12-01

For women opting to use surrogacy to overcome subfertility, a choice can be made to have a genetically related or unrelated baby. Similarly, women opting to become surrogate mothers also have to choose to gestate and relinquish a genetically related or unrelated baby. This study explored the cognitions behind the initial choices made and determined the strength of those cognitions six months post-delivery of the surrogate baby. Surrogate and Intended mothers (N=81) undergoing Artificial Insemination (AI, genetic) or Embryo Transfer (ET, gestational) were studied separately (four groups) at the start of their surrogate arrangement and those with a positive outcome (n=34) were re-interviewed at six months post-relinquishment. There were significant differences between surrogate and intended mothers in their confidence about the arrangement. Beliefs about the importance of a genetic link were predictors of ET arrangements. Responses were consistent over a one and a half-year study period. The ethical and clinical implications of the results are discussed in relation to appropriate self-selection and confidence with the surrogate process and the importance of genetic offspring.

The chemical states of sulfur in 11 tires were analyzed using X-ray absorption near-edge structure (XANES) in order to discriminate between various tire rubbers. All tires had peaks around 2471.5 and 2480.5eV, and the shapes and heights of these peaks differed among tires, suggesting that the sulfur chemical state could be used for discrimination between tire rubbers. Based on t-tests on the results of XANES, 43 of 55 combinations were different at a significance level of 5%. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

1993-03-15

The recycled automobile tires in 1991 amounts to 87%, and the tires are used most effectively for heat generation. The utilization of tires for heat in Japan and in other countries are outlined, and a detailed report is made on the use of used tires as fuel at coal cogeneration plants in tire manufacturing plants. The 'utilization percent for heat' is steadily increasing among the recycling applications of used tires. Energy recovery by dry distillation method and by direct combustion method is discussed. The states of used tire utilization in America, West Germany, and Britain are introduced. A concrete example of utilization for heat of used tires at a tire manufacturing plant is shown. Used tires are chopped into chips, mixed and burned in a coal boiler, the generated steam is used as the heat source for private power generation, and the power is used as the power source for the plant. 15 refs., 5 figs., 7 tabs.

NUMERICAL MODELLING AND EXPERIMENTAL INFLATION VALIDATION OF A BIAS TWO-WHEEL TIRE

Directory of Open Access Journals (Sweden)

CHUNG KET THEIN

2016-02-01

Full Text Available This paper presents a parametric study on the development of a computational model for bias two-wheel tire through finite element analysis (FEA. An 80/90- 17 bias two-wheel tire was adopted which made up of four major layers of rubber compound with different material properties to strengthen the structure. Mooney-Rivlin hyperelastic model was applied to represent the behaviour of incompressible rubber compound. A 3D tire model was built for structural static finite element analysis. The result was validated from the inflation analysis. Structural static finite element analysis method is suitable for evaluation of the tire design and improvement of the tire behaviour to desired performance. Experimental tire was inflated at various pressures and the geometry between numerical and experimental tire were compared. There are good agreements between numerical simulation model and the experiment results. This indicates that the simulation model can be applied to the bias two-wheel tire design in order to predict the tire behaviour and improve its mechanical characteristics.

Blast overpressure after tire explosion: a fatal case.

Science.gov (United States)

Pomara, Cristoforo; D'Errico, Stefano; Riezzo, Irene; Perilli, Gabriela; Volpe, Umberto; Fineschi, Vittorio

2013-12-01

Fatal blast injuries are generally reported in literature as a consequence of the detonation of explosives in war settings. The pattern of lesion depends on the position of the victim in relation to the explosion, on whether the blast tracks through air or water, and whether it happens in the open air or within an enclosed space and the distance from the explosion. Tire explosion-related injuries are rarely reported in literature. This study presents a fatal case of blast overpressure due to the accidental explosion of a truck tire occurring in a tire repair shop. A multidisciplinary approach to the fatality involving forensic pathologists and engineers revealed that the accidental explosion, which caused a series of primary and tertiary blast wave injuries, was due to tire deterioration.

Spray From a Rolling Tire: Mechanics of Droplet Formation

Science.gov (United States)

Plocher, Dennis; Browand, Fred

2010-11-01

The spray pattern immediately behind a single-groove tire rolling on a wet surface is produced in the laboratory using a specially designed tire spray simulator. The spray development is examined using high speed video. Water from the groove forms a liquid sheet as the tire-tread lifts away from the surface. The sheet is not of uniform thickness, but it remains attached to the tread. The thinner portions of the sheet become even thinner as the tire rotates, and eventually break to produce holes near the tire surface. The holes grow as the sheet margins surrounding the holes retract into the thicker portions of the sheet which become roughly cylindrical "ligaments" aligned at right angles to the direction of spray motion. The ligaments break into large droplets via a Rayleigh instability. The smallest droplets form when the margins of two holes collide. As Weber number, We = ρU^2w/2σ , based on tire groove half width, w/2, varies by a factor of 25, the sheet-ligament structure persists, but ligaments become less organized, and more small droplets appear in the pattern.

Umbilical cord blood banking is one of many biomedical innovations that confront pregnant women with new choices about what they should do to secure their own and their child's best interests. Many mothers can now choose to donate their baby's umbilical cord blood (UCB) to a public cord blood bank or pay to store it in a private cord blood bank. Donation to a public bank is widely regarded as an altruistic act of civic responsibility. Paying to store UCB may be regarded as a "unique opportunity" to provide "insurance" for the child's future. This paper reports findings from a survey of Australian women that investigated the decision to either donate or store UCB. We conclude that mothers are faced with competing discourses that force them to choose between being a "good mother" and fulfilling their role as a "good citizen." We discuss this finding with reference to the concept of value pluralism.

Baby Skyrmion chains

2010-01-01

The Baby Skyrmion model is a two-dimensional analogue of the full three-dimensional Skyrme model. It is not just useful for guiding investigations in the Skyrme model, it also has applications in condensed matter physics. Previous results on multi-charged Baby Skyrmion solutions have pointed to a modular structure, comprised of charge two rings and single charge one Skyrmions, which combine to form higher charged structures. In this paper we present alternative numerical solutions that correspond to new finite Baby Skyrmion chains, which have lower energy than those found previously, and are also good candidates for the global minimum energy solutions. We then proceed from the infinite plane, to Baby Skyrmions on a cylinder and then a torus, to obtain the solutions of periodic Baby Skyrmions, of which periodic segments will correspond to sections of large charge Baby Skyrmions in the plane

The efficacy of maximum label rates of bifenthrin applications to dry tires to prevent Aedes mosquito breeding was investigated by field colonization and bioassay trials in shaded and unshaded locations. Aedes notoscriptus and Culex quinquefasciatus larvae were the most abundant species present in the field colonization trial. Colonization and survival of Ae. notoscriptus larvae to the late instar occurred significantly earlier in treated tires in shaded compared with unshaded locations (P = 0.002). Bifenthrin applications in shaded tires only prevented early instar survival for approximately 2.6 wk. Aedes notoscriptus late instars did not appear in the treated unshaded tires. Culex quinquefasciatus colonized treated tires from the 2nd wk in both shaded and unshaded treatments. In the bioassay, water from bifenthrin-treated tires, through extrapolation, was found to kill approximately 100% of late instar Ae. notoscriptus for only approximately 2.0-2.2 wk in shaded and unshaded tires. Under conditions optimal for Aedes breeding, such as shaded locations, high ambient temperatures, high relative humidity, and high amounts of leaf/organic matter accumulations, bifenthrin may not be effective as a larval control measure in tires for greater than 2.0-2.6 wk.

Who benefited from the US tariffs on the Chinese tires?

The purpose of this paper is to evaluate the short-run effect of the tariffs on Chinese tires imposed by the US in September 2009. First, we investigated whether the tariffs were beneficial to the US domestic tire industry in terms of employment. Our empirical analysis found that there were no significant benefits to US employment in the tire industry. This result led us to the next question: Who benefited from the tariffs? We found that the tire imports to the US were significantly deviated ...
