Variability in Ethiopian coriander accessions for agronomic and quality traits

Coriander (Coriandrum sativum L.) is an annual spice herb that belongs to the family of Umbelliferae/Apiaceae. Although Ethiopia is known as a primary diversity for coriander, the knowledge on nature and extent of variation of the indigenous germplasm is limited. Hence, to address the nature and extent of variability on agronomic and chemical traits, test trial was conducted at Kokate and Wondo Genet, Southern Ethiopia, using 49 accessions arranged in randomised complete block design in two replications during the main season of 2007/08. Data for 15agronomic and quality traits were measured and statistically tested. In the combined analysis of variance over locations, accessions varied significantly in all the traits except for basal leaf number, plant height and fatty oil contents. The interaction between accessions and environment was significant for nine of the 15 traits. A range of seed yield (910-3099 kg ha-1), essential oil (0.25-0.85%) and fatty  oil (11.11-16.53%) content was obtained. Overall, highest value of genetic coefficient of variation, broad sense heritability and genetic advance as percent of mean was obtained for longest basal leaf length, days to start 50% flowering, umbels number/plant, umbellets number/umbel, seed number/umbellets, seed number/plant, seed yield/ha and essential oil content

Married women's decision making power on family planning use and associated factors in Mizan-Aman, South Ethiopia : a cross sectional study

Background: Women's use of family planning service is influenced by many factors, especially by their decision making power. A woman's decision-making power, be it individual or decision made in collaboration with a partner, is the most important factor in the use of family planning in a household. The purpose of this study was to assess the impact of women's decision making power on family planning use and its associated factors. Methods: A community-based cross-sectional study was conducted on married women in the child bearing age. The women who were living in Mizan city were selected using the simple random sampling method. Trained nurses collected the data by interview, using a structured and pre-tested questioner. Bivariable and multivariable binary logistic regression analysis was used to identify the associated factors, and the odds ratio with a 95 % CI was computed to assess the strength of the association. Collinearity was also assessed by looking at standard errors in the final fitted model. Result: Overall, more than two-thirds [67.2 %: 95 % CI (63-71 %)] of the married women were found to be more autonomous to decide family planning use. Secondary education [AOR: 9.04, 95 % CI: (4.50, 18.16)], government employment [AOR: 4.84, 95 % CI: (2.03, 11.52)], being wives of government employed spouses [AOR 2.71, 95 % CI: (1.24, 7.97)], having husbands with college or university education [AOR: 11.29, 95 % CI: (4.66, 27.35)], and being in the younger age [AOR: 0.27, 95 % CI :(0.09, 0.75)] were significantly associated with women's decision-making power on family planning. Conclusions: In this study, women had a high decision making power in family planning use. Age category (34-44-years), formal education, and occupational status had effects on women's decision making power. Promoting parental adult education and engaging women in out of house employment is essential to improve their decision making power in using family planning

Direct approach to the problem of strong local minima in Calculus of Variations

The paper introduces a general strategy for identifying strong local minimizers of variational functionals. It is based on the idea that any variation of the integral functional can be evaluated directly in terms of the appropriate parameterized measures. We demonstrate our approach on a problem of W^{1,infinity} weak-* local minima--a slight weakening of the classical notion of strong local minima. We obtain the first quasiconvexity-based set of sufficient conditions for W^{1,infinity} weak-* local minima.Comment: 26 pages, no figure

On the variational limits of lattice energies on prestrained elastic bodies

We study the asymptotic behaviour of the discrete elastic energies in presence of the prestrain metric $G$, assigned on the continuum reference configuration $\Omega$. When the mesh size of the discrete lattice in $\Omega$ goes to zero, we obtain the variational bounds on the limiting (in the sense of $\Gamma$-limit) energy. In case of the nearest-neighbour and next-to-nearest-neibghour interactions, we derive a precise asymptotic formula, and compare it with the non-Euclidean model energy relative to $G$

The role of culture and religion on sexual and reproductive health indicators and help-seeking attitudes amongst 1.5 generation migrants in Australia : a quantitative pilot study

In Australia, 1.5 generation migrants (those who migrated as children) often enter a new cultural and religious environment, with its own set of constructs of sexual and reproductive health (SRH), at a crucial time in their psychosexual development—puberty/adolescence. Therefore, 1.5 generation migrants may thus have to contend with constructions of SRH from at least two cultures which may be at conflict on the matter. This study was designed to investigate the role of culture and religion on sexual and reproductive health indicators and help-seeking amongst 1.5 generation migrants. An online survey was completed by 111 participants who answered questions about their cultural connectedness, religion, sexual and reproductive health and help-seeking. Kruskall-Wallis tests were used to analyse the data. There was no significant difference between ethnocultural groups or levels of cultural connectedness in relation to sexual and reproductive health help-seeking attitudes. The results do suggest differences between religious groups in regard to seeking help specifically from participants’ parents. Notably, participants who reported having ‘no religion’ were more likely to seek help with sexual and reproductive health matters from their parent(s). Managing cross-cultural experiences is often noted in the extant literature as a barrier to sexual and reproductive health help-seeking. However, while cultural norms of migrants’ country of origin can remain strong, it is religion that seems to have more of an impact on how 1.5 generation migrants seek help for SRH issues. The findings suggest that 1.5 generation migrants may not need to adapt their religious beliefs or practices, despite entering a new ethnocultural environment. Given that religion can play a role in the participants’ sexual and reproductive health, religious organizations are well-placed to encourage young migrants to adopt help-seeking attitudes

Performance assessment of drought tolerant maize hybrids under combined drought and heat stress

Open Access Journal; Published online: 22 Nov 2018Drought and high temperature are two major factors limiting maize productivity in sub-Saharan Africa. An increase in temperature above 30 °C reduces yield by 1% under optimal rain-fed condition and by 1.7% under drought stress (DS) and up to 40% under combined drought and heat stress (DSHTS). Approaches that improve performance under the two stresses are essential to sustain productivity. The objectives of this study were to (i) assess the extent of variation in tolerance to DSHTS from among the existing best drought tolerant (DT) hybrids; (ii) examine the response patterns of the hybrids to DSHTS; (iii) identify traits that contributed to better performance under DSHTS; and (iv) select the best hybrids with tolerance to DSHTS stress. We evaluated 40 DT hybrids under DSHTS, DS, and well-watered (WW) conditions for three years. Highly significant (p < 0.001) differences were found among hybrids for grain yield and other traits. Moderately to low repeatability values were detected for grain yield under DS (0.63) and under DSHTS (0.48). Grain yield under DS was not correlated with grain yield under DSHTS (r = 0.29; p = 0.06), but it was correlated with grain yield under WW (r = 0.74; p < 0.001). Grain yield was strongly correlated with ears per plant, ear and pant aspects, days to anthesis and silking under both DS and DSHTS. Tassel blast accounted for 28% of the yield reduction under DSHTS. The top five DT hybrids produced 9 to 26% more grain yields than the best commercial hybrid. Three hybrids produced high grain yields under DTHTS and DS as well as under WW. These hybrids will be tested further in collaboration with partners for possible release

Visceral leishmaniasis patients display altered composition and maturity of neutrophils as well as impaired neutrophil effector functions

Immunologically, active visceral leishmaniasis (VL) is characterised by profound immunosuppression, severe systemic inflammatory responses and an impaired capacity to control parasite replication. Neutrophils are highly versatile cells, which play a crucial role in the induction as well as the resolution of inflammation, the control of pathogen replication and the regulation of immune responses. Neutrophil functions have been investigated in human cutaneous leishmaniasis, however, their role in human visceral leishmaniasis is poorly understood. In the present study we evaluated the activation status and effector functions of neutrophils in patients with active VL and after successful anti-leishmanial treatment. Our results show that neutrophils are highly activated and have degranulated; high levels of arginase, myeloperoxidase and elastase, all contained in neutrophils’ granules, were found in the plasma of VL patients. In addition, we show that a large proportion of these cells are immature. We also analysed effector functions of neutrophils that are essential for pathogen clearance and show that neutrophils have an impaired capacity to release neutrophil extracellular traps, produce reactive oxygen species and phagocytose bacterial particles, but not Leishmania parasites. Our results suggest that impaired effector functions, increased activation and immaturity of neutrophils play a key role in the pathogenesis of VL
