It was found that both herbicides in both doses showed good selectivity in relation to bird's–foot trefoil. Most pronounced was the effect by the applied herbicides regarding the degree of weed infestation in the year of sowing, as the treatment by Aramo 45 at a dose of 2 L/ha and Dual Gold 960 EC at a dose of 2 L/ha provided a degree of weed infestation of 6.68 and 16.11 %. The vegetation treatment of a grassland of bird's– foot–trefoil by Aramo 45 herbicide at a dose of 1 and 2 L/ha led to an increase in dry matter yield with 21.85 and 18.21 %, and with Dual Gold 960 EC EK it was 24.28 and 30.29 %. Dual Gold 960 EC showed a greater effect from both tested herbicides over the dry matter yield, applied at a dose of 3 l/ha at a phase of 2–4 leaf stage of bird's–foot trefoil. That herbicide could be recommended for the application in the practice in creating weed–free crops of bird's–foot–trefoil for forage production.

Even the waste generated from the food industries is being considered as an alternative to produce natural antimicrobials. The aim of the present study was to utilize the waste generated from the citrus fruit processing (peel) industry.

It was also observed that YYB+CP and cow paunch (CP) produced almost equal quantity of cumulative biogas yield of 398.76 mL/TMS within the first 15 days of observation compared with cumulative biogas yield 178.45 mL/TMS produced by yellow yam brute (YYB) within the same HRT. It was also observed that gas production reduced seriously in mono–digested substrates YYB and Cp compared with the co–digestate because of lack of synergistic nutrients. It is generally observed that co–digestion of more than one substrate increase cumulative biogas yield. The trend of cumulative biogas yield at the end of 35 days hydraulic retention time was YYB+CP > CP > YYB.

Method: A cross–sectional study was conducted at selected health facilities in different parts of Ethiopia from October 2011 to March 2012. A questionnaire survey was administered for all health professionals to gather information on their knowledge, altitude and perception towards toxoplasmosis. Result: From health professionals, 63 % know health risk of domestic animals like cat with regards to toxoplasmosis. Consumption of raw or undercooked meat and vegetables (71.2 %) were recognized as the common source of T. gondii infection by health professional's consumption of raw milk (18.4 %), contact with cat faces (14.3 %), and drinking unboiled water (6.1 %) were also mentioned as important modes of transmission. In this study, 52.7 % of health professionals thought toxoplasmosis as important pathogen in HIV infected patients and pregnant women. Conclusion and recommendation: The authors concluded that there is urgent need of incorporating zoonotic diseases concept in the medical education and training.

Two table vine varieties-Misket Rusenski and Super ran Bolgar were the objective of the study, grafted on two different SO4 rootstocks (which is widely used in practice and thus accepted control) and Rupestris du Lot (with common name Montikola). A total of 12 technological traits were reported for both varieties during the vegetation. Data obtained were statistically analyzed using Fisher (F) and Student (t) evaluation criteria. The results showed different levels of significance of the individual traits in both varieties using Rupestris du Lot rootstock compared to the control. Via Fisher's criterion it was found that 58 % of the traits showed significant differences in Montikola rootstock compared to the control, as the comparison was made based on variability of the traits, while when using the Student criterion for statistical evaluation, the percentage was only 33. The highest significance was reported in the influence of the rootstock on the traits: number of seeds in 100 berries and resistance of berry to pick up from the fruit stalk for cv. Misket Rusenski, determined via both criteria. Comparing the samples tested regarding variability, significant differences were reported of Rupestris du Lot rootstock for the traits: % of berries in grapes and % of mesocarp in berry mass for the same variety. Rupestris du Lot rootstock has significant influence on content of sugars, total acids and mass of 100 seeds in cv. Super ran Bolgar (by the criterion of Fisher) and traits: % of mesocarp of berry mass and % of skin of berry mass (found by the criterion of Student). These traits influence significantly on tasting qualities of grapes and technological qualities of wine. As a result of the analysis of both vines (Misket Rusenski and Super ran Bolgar) a high degree of variability of the values of some technological traits was determined, and it is recommended both criteria to be used for better statistical evaluation.
