  • Nutritional Value and Associated Potentials Risks of Seafood Consumption

    Seafood provides essential nutrients to the body. A study funded by CDC found that eating seafood for essential Omega-3 fatty acids can prevent 84,000 deaths each year [1-3]. According to a Harvard study, 3-ounce servings of fatty fish a week reduces the risk of dying from heart disease by nearly 40% [4]. Eating 8 two servings of fish per week during pregnancy can improve baby’s IQ, cognitive development, and eye health [5,6]. Older adults with the highest fish consumption live and average of 2.2 years longer [7]. But all these statements possess another side of the coin. Food-born poisoning, mercury-lead-arsenic-cadmium poisoning, exposure to polycyclic aromatic hydrocarbons (PAHs) raised the issue of safety with aberrant consumption of seafoods. Seafood choices that are very low in mercury include: salmon, sardines, pollock, flounders, cod, tilapia, shrimp, oysters, clams, scallops and crab. The U.S. Food and Drug Administration (FDA) and Environmental Protection Agency (EPA) have developed directions to help consumers minimize risks that could be associated with several pollutants (specially mercury) in seafood.

  • Discussion on the Design of Cultural Commercial Complex—Taking a design of a cultural and commercial complex next to a university in Yichang as an example

The test data is trained 2000 times so that the vector of each weight is located at the center of the input vector cluster, and the 6*6 competitive network is constructed. The network classifies or eliminates the screening of data, and obtains a healthy sample library that can be used to predict the running state of the machine in the future, achieving a good data cleaning effect.

  • Evaluation of Fungicides with the combinations of Potato (Solanum tuberosum L.) Varieties to Manage Late Blight (Phytophthora infestans (Mont) de Bary) in Highlands of Guji Zone, Southern Ethiopia

    Potato late blight (Phytophthora infestans (Mont.) de Bary) is one of the most devastating plant diseases world-wide and is feared globally by farmers and industry. There is little information on the type of fungicide to be sprayed to control late blight for optimum production of the crop in the study area. Therefore, an experiment was conducted at Bore Agricultural Research Center, Southern Ethiopia during the 2015 and 2017 cropping season to evaluate fungicides with the combination of Potato varieties to manage late blight and to assess the cost and benefits of different fungicides on Gudanie and Jalenie potato varieties. The treatments consisted of two (2) Potato varieties Gudanie and Jalenie currently under production but differ in their late blight reaction and three (3) fungicides Ridomil Gold MZ 63.5%WP, Mancozeb 80% WP2 and Matico and one (1) unsprayed treatments were used as experimental materials. The experiment was laid out as a Randomized Complete Block Design (RCBD) in a 4 x 2 factorial arrangement and replicated three times per treatment. The improved potato varieties called Gudanie and Jalenie were planted as the test crop in a plot size of 3 m * 2.1 m with intra and inter-row spacing of 0.30 and 0.75 m respectively. Data were collected on growth, yield, yield components and disease incidence and severity. The two years combined data analysis results revealed that the interaction effect of fungicides and potato varieties had influenced significantly (P0.05) effect on days to50% emergency and average tuber weight. The two year data analysis the highest (47.34 t ha-1and 46.31 tha-1) marketable tuber yield was obtained from Gudanie variety with Ridomil Gold fungicide spraying at Bore on-station and Ana sora on-farm both locations respectively. The result of 2015 year disease data indicates that maximum (59.52% and 3.67) disease incidence and severity, respectively was…

  • Community Based Forest Management (CBFM) in Ethiopia: Progress and Prospects

    This paper critically reviewed the status of Participatory or Community Based Forest Management (CBFM) in the case of Ethiopia. Ethiopia is located in the Horn of Africa between 3o and 15o North latitude and 33o and 48o east longitude. The country covers 1.13 million square kilometers, with a wide altitudinal variation ranging from 110 meters below sea level (b.s.l.) in Kobar Sink (Dallol) to 4,620 meters above sea level (a.s.l.) at Ras Dashen (Ras Dejen). The Great African Rift Valley runs diagonally across the country from northeast to southwest separating the western and southeastern highlands. This physiographic feature enabled the ecosystems to host a great diversity of flora and fauna resources. The flora of Ethiopia is estimated to comprise about 6,500-7,000 plant species; 12 per cent of these plant species considered as endemic. Forests provide numerous ecosystem services, products for human consumption, and habitat for countless species. Unfortunately, deforestation has occurred at alarming scales and its effects have threatened environmental and livelihood sustainability. In Ethiopia, for the most part, forests have been managed under the support of national agencies, often with the exclusion or outright removal of local people. No sustainable forest management program has been put in place due to lack of adequate funding and stable structural set up for the forestry sector. To combat this problem Participatory or Community Based Forest Management (CBFM) is accepted throughout the world and in Ethiopia currently. This is due to the recognition that communities are the direct users of the forests and no one can care adjacent forests without the full involvement of the society. CBFM is one attempt to reverse deforestation, and, by doing so, preserves ecological services and products that provide local communities with ways to secure livelihoods. CBFM has also grown in practice because centralized management of natural resources…


    The objective of this paper was to review milk processing techniques and consumption rate in West African Sub-Region. The Nigerian dairy industry represents an important component of the agribusiness sector of the economy with great economic, nutritional, and social benefits. Processing of fresh milk is achieved by local techniques into various traditional milk products. About 47kg of liquid milk per individual is consumed per year in Nigeria compared to an average of 25kg for the sub-Saharan Africa region. Consumers display strong preference for locally produced and processed products such as nono (sour milk), kindirmo (sour yoghurt), maishanu (local butter), cuku (Fulani cheese) and wara (Yoruba cheese). The choice of preference is based on flavour, perceived nutritional value and regional customs and beliefs. Similarly, the local products are believed to be cheaper than their imported counterparts. Sour milk and local butter accounted for over 30% of all dairy products consumption. Urban household consume about 20% more dairy products than rural household. Pastoralists are mostly the producers, but consume less of the products. Modern milk processing techniques and higher consumption rate should be encouraged in West African Sub-Region to ensure improved human and animal productivity in the region.

  • Prevalence of Ovine Haemonchosis and Associated Risk Factors in Jimma Municipal Abattoir

    Haemonchus contortus is a blood sucking nematode parasite of sheep all over the tropics and subtropics which causes retarded growth, lower productivity and even mortality in young animals. A cross sectional study was conducted from April, 2018 to May, 2018 in sheep slaughtered at Jimma municipal abattoir in Jimma town conducted using purposive. Purposively, sheep were selected during ante-mortem examination and the necessary information was recorded in data collection format. In the present study, a total of 384 sheep (217 males and 167 females) were slaughtered at the Jimma municipal abattoir and inspected for the presence or absence of the parasite. Accordingly, the findings of this study revealed that an overall prevalence of 33.1% was recorded. High prevalence of disease occur in poor body condition score 117/245(47.8) and low prevalence occur in good body condition score 10/139 (7.2%) and there was statistically significant differences (P= 0.000) between body condition scores. Among the male and female slaughtered sheep, 70 (32.3%) and 57 (34.2%) were found to be positive for H. contortus, respectively; and shows no statistical significant difference (P >0.05) between sex. Based on age group, prevalence of haemonchosis was 57 (30.5%) and 70 (35.5 %), in young and adult, respectively. The result from the present study indicated that there was no statistical significance (P > 0.05) among age groups. There is no statistical significance difference (P > 0.05) between urban and rural origin of sheep. In the present study, moderate prevalence of H. contortus was observed in sheep during the study period. Therefore, strategic prevention and control measures should be implemented to decrease the burden of the parasitic infection so as to enhance productivity of sheep in the study area.

  • Professional training in mindfulness in brazil: what is the profile of participants?

    Introduction: During the last 30 years, mindfulness interventions have been used worldwide for prevention and treatment of anxiety, depression, and chronic pain, with exponential growth of scientific evidence on the subject. Training professionals in Brazil is fundamental for the implementation of these interventions all over the country, and knowing the profile of those who seek training is important to make it more effective and accessible. Objective: To describe the professional profile of the participants of a group of the Mindfulness Instructor Training Program of the Brazilian Center for Mindfulness and Health Promotion (Open Mind – UNIFESP). Methodology: Twenty-nine volunteers from the basic module group of the mindfulness instructors training course held in September 2017 participated in this study. Data such as area of work, professional training, gender, age and city were collected from the partner questionnaire -demographic and provided by the Open Mind Center. Results: Of the 29 volunteers evaluated in this study, 79.31% were women and 20.69% were men (age = 45.44 years, ± 12.56 years). 96.56% are Brazilian, and 85.71% of these are residents of the Southeast region. Regarding the professional profile, 68.97% work in health promotion, of which 50% are psychologists, 15% are psychotherapists and 10% are doctors. Discussion and Conclusion: The data obtained by this pilot study indicate that the standard profile of professionals seeking mindfulness training are psychologist women aged 45.44 years living in southeastern Brazil. It is important to emphasize that more comprehensive studies are necessary so that we can understand the professional profile of professionals who seek the Instructor Training of mindfulness in order to make such programs more effective and accessible for Brazilian professionals.
