Determinants of Dietary Adequacy Among School Age Children in Guraghe Zone, Southern Ethiopia

Dietary diversity (DD) is a validated proxy indicator of micronutrient adequacy among different age groups including infants, children and women. This study assessed level of dietary adequacy and its associated factors among school age children in Guraghe Zone, Ethiopia. Survey was conducted among 769 children aged 6 to 12 years of with their care givers using multistage sampling method. Data were collected by using structured questionnaire containing the ten food groups for minimum dietary diversity for women and other parts. Adequate dietary diversity was categorized those children who consume at least five food groups. Bivariate and multivariable binary logistic regression with odds ratios (95% CI) was computed. Overall 769 children were included in the study, with a mean age of 8 years. The mean dietary diversity score was 4.9 (±1.42). About 444 (58.3%) had an inadequate dietary diversity. Those children from extended family size had 1.3 times to have inadequate DD level (AOR=1.3). Children from female headed households, did not attend formal education had 1.3 and 1.4 times higher odds of having an inadequate DD level (AOR=1.3 and 1.4). Similarly, children living with uneducated caregiver had six fold more likely to have an adequate DD level (AOR=6.7). The dietary diversity of children in the study area was below average. Household head, caregiver\u27s educational status, occupation of the household head, father/female headed household and family size were found to be associated with DD score. There should be awareness creation through existing Health extension platform and back yard vegetation should be improved

Cattle milk and meat production and marketing systems and opportunities for market-orientation in Fogera woreda, Amhara region, Ethiopia

This study was conducted in Fogera woreda, South Gondar Zone of the Amhara National Regional State in northwestern Ethiopia in 2005/06. The aim was to characterize cattle milk and meat production and marketing systems, identify the major constraints and provide development interventions for more market-orientation. Twelve kebeles were randomly selected (five from the Fogera plains and seven outside the plains) based on their potential for cattle milk and meat production. A total of 480 households were sampled from these kebeles and focus group discussion, personal observations and administration of semi-structured questionnaires on milk and meat production practices were employed. Only 12 (2.52%) of the respondents were female-headed households. About 98.8% of cattle milk and meat production was based on traditional husbandry using indigenous cattle breeds. The Fogera cattle is the major breed used and is mainly found in the Damote, Sendeye and Tigre mender villages. The main feed resources in the woreda are communal grazing land and crop residues of teff, rice, finger millet, barley, wheat, chickpea, field pea and maize. The communal grazing land currently accounts for about 9602.4 ha; out of which 3418.5 ha (35.6%) is infested by a noxious weed known as Asracantha longifolia (amykila). Over a period of two years, large area of communal grazing land has been transformed into crop farms, mainly to rice production, and this has apparently created severe feed shortage in the woreda. Flooding of the plains during the wet season from Gumara and Rib rivers further reduced the availability of grazing land. In addition, large number of animals are trekked from the highlands of Fogera and adjacent woredas of Dera and Estie to the plains during the dry season and this has resulted in inter-breeding of the Fogera cattle breed with highland zebus and has exacerbated the feed shortage. Rice husk, a by-product from rice polishers, is becoming an important feed resource. On average, about 35 kg of rice husk is produced from a quintal of rice. The major water resources are wells (48.8%), rivers (47.2%), lake (3%), ponds (2.3%) and tap water (0.2%). Cattle are watered once a day. Trypanosomiasis, facioliasis and schistosomiasis are the most prevalent diseases

Observation of resonant interactions among surface gravity waves

We experimentally study resonant interactions of oblique surface gravity waves in a large basin. Our results strongly extend previous experimental results performed mainly for perpendicular or collinear wave trains. We generate two oblique waves crossing at an acute angle, while we control their frequency ratio, steepnesses and directions. These mother waves mutually interact and give birth to a resonant wave whose properties (growth rate, resonant response curve and phase locking) are fully characterized. All our experimental results are found in good quantitative agreement with four-wave interaction theory with no fitting parameter. Off-resonance experiments are also reported and the relevant theoretical analysis is conducted and validated.Comment: 11 pages, 7 figure

Magnetic field reversals in an experimental turbulent dynamo

We report the first experimental observation of reversals of a dynamo field generated in a laboratory experiment based on a turbulent flow of liquid sodium. The magnetic field randomly switches between two symmetric solutions B and -B. We observe a hierarchy of time scales similar to the Earth's magnetic field: the duration of the steady phases is widely distributed, but is always much longer than the time needed to switch polarity. In addition to reversals we report excursions. Both coincide with minima of the mechanical power driving the flow. Small changes in the flow driving parameters also reveal a large variety of dynamo regimes.Comment: 5 pages, 4 figure

Generation of magnetic field by dynamo action in a turbulent flow of liquid sodium

We report the observation of dynamo action in the VKS experiment, i.e., the generation of magnetic field by a strongly turbulent swirling flow of liquid sodium. Both mean and fluctuating parts of the field are studied. The dynamo threshold corresponds to a magnetic Reynolds number Rm \sim 30. A mean magnetic field of order 40 G is observed 30% above threshold at the flow lateral boundary. The rms fluctuations are larger than the corresponding mean value for two of the components. The scaling of the mean square magnetic field is compared to a prediction previously made for high Reynolds number flows.Comment: 4 pages, 5 figure

Transport of magnetic field by a turbulent flow of liquid sodium

We study the effect of a turbulent flow of liquid sodium generated in the von K\'arm\'an geometry, on the localized field of a magnet placed close to the frontier of the flow. We observe that the field can be transported by the flow on distances larger than its integral length scale. In the most turbulent configurations, the mean value of the field advected at large distance vanishes. However, the rms value of the fluctuations increases linearly with the magnetic Reynolds number. The advected field is strongly intermittent.Comment: 4 pages, 6 figure

Factors Associated with Late Initiation of Antenatal Care among Pregnant Women Attending Antenatal Clinic at Public Health Centers in Kembata Tembaro Zone, Southern Ethiopia

The purpose of this study was to identify those factors associated with late initiation of antenatal care among pregnant women attending antenatal clinics in public health centers in Kembata Tembaro Zone, Ethiopia. A facility based cross-sectional study with supplement of qualitative data was carried out to collect data from 401 pregnant women who were attending antenatal care service at five randomly selected governmental health centres in Kembata Tembaro Zone from March 10 to May 8, 2012 .  Pretested and structured questionnaire was used to collect the data and data were entered onto a computer using Epi-info 3.5.1 statistical program then exported to SPSS Windows version 16.0 for further analysis. Binary descriptive statistics and multiple variable regressions were done.This study showed that prevalence of late entry to antenatal care was 68.6%. The mean timing was 5.5±1.8 months. Multivariate analysis revealed that age, maternal education, family income, parity, previous utilization of antenatal care and type of pregnancy remained significant factors influencing late booking. The findings of this study showed that most women book antenatal care late. This seems to be because antenatal care is viewed primarily as curative rather than preventive in the study population. Public enlightenment, health education coupled with women empowerment would be helpful in reducing the problem. In addition to that incorporation of the benefits of early booking in the routine antenatal care education
