Socioeconomic evaluation of wild rice as famine food crop in Southern Darfur State, Sudan

Wild rice (Oryza barthii) is increasingly used in Sudan as a food crop. Wild rice is a whole grain, rich in minerals, vitamins, protein, starch, dietary fiber and various phytochemicals; and yet low in fat, with a beneficial fatty acids profile. The objective of this study was to evaluate the socioeconomic significance of wild rice as a famine food crop in Darfur state of Sudan. A study was conducted in five districts (Tullus, Gadad, Demso, Katila, and Umshtoor) in South Darfur in Sudan. Primary data were obtained through a face-to-face semi-questionnaire interview on 146 households; supplemented with interviews of key informants and group discussions. All respondents (100%) not only attested to knowing wild rice and its growth habits, but also consumption (93.8%) of the crop. Wild rice reportedly grows naturally and widely in valleys, although it was dismally exploited by the local population. It is harvested manually and traditionally; and sold mostly in the local markets, without post-harvest value additions. The crop is consumed in various meals, but mainly in the form of porridge. Some respondents (13%) used the crop in times of famine. Wild rice is stored in traditional containers (95.9%) for periods ranging from 8 to 12 years without visible storage problems. &nbsp

Anti-inflammatory Activity of the Plant Cannabis sativa (L) Petrolium Ether Extract in Albino Rats

In this study the plant Cannabis sativa seeds petroleum oil extract was investigated for anti- inflammatory activity on albino rats. The inflammation was firstly obtained by using carrageenan suspension 0.1 ml of 10% saline injected at the sub – plantar region of the left limb for inducing a local acute oedema. A decreased in oedema size was reported after 24 hours for the rats pretreated with carrageenan30 minutes before injection with suspension( 4.56, 0.59 and 0.93 for control, 1ml/kg per day and 0.5ml/kg per day groups given C. sativa seed extracts respectively.), compared to Indomethacin standard antiinflammatory drug which reported a decrease in oedema size diameter to 0.55mm, which indicated an increase inhibition percentages were reported for the different pretreated groups 0.00, 87.03, 79.56 and 87.91 including the comparative Indomethacin treated groups of rats respectively. On the other hand, the post-treated groups of rats (given C. sativa oil extract after 30 minutes of injection of suspension) showed a similar results for maximum concentration 1 ml/day of C. sativa oil extract in comparison to the standard drug. Hence, such results recommend the prospect focus for the preventive medication use of the extract. The study also highlights no significant changes for serum and protein of the blood taken from rats of the experiments. Although there were significant decrease in lymphocyte and neutrophil, but the changes were not significant. Indomethacin was given to the rats used for a comparative drug (10mg/kg). Moreover, the drug indomethacin used as a comparative parameter showed similar results in comparison to the extract, hence wise the reported results may be recommended for use as anti-inflammatory agent and should be explored more to formulate drug on basis of its activity

SOCIO-DEMOGRAPHIC RELATIONSHIPS AND MANAGEMENT REGIMES ON USE OF FRUNDU AS FERMENTED FAMINE FOOD IN URBAN NORTHERN DARFUR IN SUDAN

Frundu, which in a local term in Darfur for fermented seeds of roselle ( Hibiscus sabdariffa L.), is a traditional Sudanese food often used as a meat substitute during famine times. The objective of this study was to assess the relationships between socio-demographic and management regimes on the use of Frundu as a food security commodity in urban Darfur in Sudan. A survey involving 140 respondents was conducted in El-Fashir city markets, where Frundu is a popular commodity in Darfur markets. A semi-structured questionnaire and Chi square analysis were used. It was found that the period of fermentation of Frundu ranged from 3 to 7 days, depending on seasonal temperature. The storage period of Frundu was on average one year. Over 55% of the respondents acknowledged Frundu as critical a coping strategy when famine struck Darfur and the majority of respondents were familiar with Frundu. Frundu is becoming less popular in Darfur for several reasons; including difficulty in obtaining Roselle seeds, competition from the cheapest food items especially during non-famine time; and lack of familiarity with Frundu among young generations. To boost its production, processing and utilisation, farmers should be encouraged to increase its cultivation particularly because it is an important cash crops in Sudan.Frundu, qui est les graines ferment\ue9es de roselle dans un terme local au Darfour (Hibiscus sabdariffa L.), est un aliment traditionnel soudanais souvent utilis\ue9 comme substitut de viande en p\ue9riode de famine. L\u2019objectif de cette \ue9tude \ue9tait d\u2019\ue9valuer les relations entre les r\ue9gimes socio-d\ue9mographiques et de gestion sur l\u2019utilisation du Frundu comme produit de s\ue9curit\ue9 alimentaire dans le Darfour urbain au Soudan. Une enqu\ueate aupr\ue8s de 140 r\ue9pondants a \ue9t\ue9 men\ue9e sur les march\ue9s de la ville d\u2019El-Fashir la o\uf9 Frundu est un produit populaire sur les march\ue9s du Darfour. Un questionnaire semi-structur\ue9 et une analyse du chi carr\ue9 ont \ue9t\ue9 utilis\ue9s. Il a \ue9t\ue9 constat\ue9 que la p\ue9riode de fermentation du Frundu variait de 3 \ue0 7 jours, selon la temp\ue9rature saisonni\ue8re. La dur\ue9e de conservation du Frundu \ue9tait en moyenne d\u2019un an. Plus de 55% des personnes interrog\ue9es ont reconnu Frundu comme une strat\ue9gie d\u2019adaptation essentielle lorsque la famine a frapp\ue9 le Darfour et la majorit\ue9 des personnes interrog\ue9es connaissaient Frundu. Frundu devient moins populaire au Darfour pour plusieurs raisons ; y compris la difficult\ue9 \ue0 obtenir des graines de Roselle, la concurrence des produits alimentaires les moins chers, en particulier dans la p\ue9riode d\u2018 abondance; et le manque de familiarit\ue9 avec Frundu parmi les jeunes g\ue9n\ue9rations. Pour stimuler sa production, sa transformation et son utilisation, les agriculteurs devraient \ueatre encourag\ue9s \ue0 augmenter la culture de Frundu, parce que Frundu est une plante de cueillettes commerciales au Soudan

INDIGENOUS KNOWLEDGE-BASED EVALUATION OF AMBACHI TUBEROUS PLANT AS A FUTURE FAMINE FOOD CROP FOR DARFUR STATE, SUDAN

Malnutrition and associated diseases are major challenges in the semi-arid Sahelian zone of Africa, where rainfall is <600 mm per annum. The objective of this study was to document indigenous knowledge on the significance and management of Ambachi ( Dioscorea hispida ) in East Darfur State, Sudan. A total of 101 respondents was interviewed using a semi-structured questionnaire in Bahr Alarab Locality, located in East Darfur State. Additionally, key informants and group discussions were held with local leaders to supplement data collection. The results revealed that Ambachi plant is fairly plentiful in East Darfur state, and grows naturally in the wild. All respondents were knowledgeable about Ambachi plant\u2019s appearance, growth cycle, usage and storage processes. Generally, Ambachi tubers are stored in various types of natural and synthetic containers, and for varied periods of time. However, up to 78% of the respondents reported Shawwal (made of plastic material), as the most preferred container for storage of dry tubers. Virtually all households (99%) attested to consuming Ambachi-based foods particularly during famine periods. Up to 98% of Ambachi plant tubers are soaked before cooking to remove the bitter taste; and two thirds of interviewees were familiar with the cooking process of Ambachi foods. Lastly, Ambachi plant tubers are tradable in different local markets across the region; although it was mainly sold in Abu matareg market located in Bahar Alara locality.La malnutrition et les maladies associ\ue9es sont des d\ue9fis majeurs dans la zone sah\ue9lienne semi-aride de l\u2019Afrique o\uf9 la pr\ue9cipitation est inf\ue9rieure \ue0 600 mm par an.

Search for Higgs bosons decaying to tautau pairs in ppbar collisions at sqrt(s) = 1.96 TeV

We present a search for the production of neutral Higgs bosons decaying into tautau pairs in ppbar collisions at a center-of-mass energy of 1.96 TeV. The data, corresponding to an integrated luminosity of 5.4 fb-1, were collected by the D0 experiment at the Fermilab Tevatron Collider. We set upper limits at the 95% C.L. on the product of production cross section and branching ratio for a scalar resonance decaying into tautau pairs, and we then interpret these limits as limits on the production of Higgs bosons in the minimal supersymmetric standard model (MSSM) and as constraints in the MSSM parameter space.Comment: 7 pages, 5 figures, submitted to PL

Measurement of three-jet differential cross sections d sigma-3jet / d M-3jet in p anti-p collisions at sqrt(s)=1.96 TeV

We present the first measurement of the inclusive three-jet differential cross section as a function of the invariant mass of the three jets with the largest transverse momenta in an event in p anti-p collisions at sqrt(s) = 1.96 TeV. The measurement is made in different rapidity regions and for different jet transverse momentum requirements and is based on a data set corresponding to an integrated luminosity of 0.7 fb^{-1} collected with the D0 detector at the Fermilab Tevatron Collider. The results are used to test the three-jet matrix elements in perturbative QCD calculations at next-to-leading order in the strong coupling constant. The data allow discrimination between parametrizations of the parton distribution functions of the proton.Comment: 10 pages, 4 figures, 2 tables, submitted to Phys. Lett.

Search for pair production of the scalar top quark in muon+tau final states

We present a search for the pair production of scalar top quarks ($\tilde{t}_{1}$), the lightest supersymmetric partners of the top quarks, in $p\bar{p}$ collisions at a center-of-mass energy of 1.96 TeV, using data corresponding to an integrated luminosity of {7.3 $fb^{-1}$} collected with the \dzero experiment at the Fermilab Tevatron Collider. Each scalar top quark is assumed to decay into a $b$ quark, a charged lepton, and a scalar neutrino ($\tilde{\nu}$). We investigate final states arising from $\tilde{t}_{1} \bar{\tilde{t}_{1}} \rightarrow b\bar{b}\mu\tau \tilde{\nu} \tilde{\nu}$ and $\tilde{t}_{1} \bar{\tilde{t}_{1}} \rightarrow b\bar{b}\tau\tau \tilde{\nu} \tilde{\nu}$. With no significant excess of events observed above the background expected from the standard model, we set exclusion limits on this production process in the ($m_{\tilde{t}_{1}}$,$m_{\tilde{\nu}}$) plane.Comment: Submitted to Phys. Lett.

Measurements of inclusive W+jets production rates as a function of jet transverse momentum in ppbar collisions at sqrt{s}=1.96 TeV

This Letter describes measurements of inclusive W (--> e nu) + n jet cross sections (n = 1-4), presented as total inclusive cross sections and differentially in the nth jet transverse momentum. The measurements are made using data corresponding to an integrated luminosity of 4.2 fb-1 collected by the D0 detector at the Fermilab Tevatron Collider, and achieve considerably smaller uncertainties on W +jets production cross sections than previous measurements. The measurements are compared to next-to-leading order perturbative QCD (pQCD) calculations in the n =1-3 jet multiplicity bins and to leading order pQCD calculations in the 4-jet bin. The measurements are generally in agreement with pQCD predictions, although certain regions of phase space are identified where the calculations could be improved
