Heat and moisture production in growing-finishing pigs and broilers CIGR Journal
Aarnink-FBC, Andre.
Heat and moisture production are important parameters for designing ventilation and climate control systems in livestock housing. In 2002 a report was published of the CIGR Section II Working Group on Climatization of Animal Houses ‘Heat and moisture production at animal and house levels’ with formula to calculate heat and moisture production for different livestock categories. The objective of this paper is to discuss these CIGR formula for growing-finishing pigs and broilers. Results from calculated heat and moisture production with the relatively simple formula in the CIGR report were compared with results from a more comprehensive model. From this comparison the following conclusions were drawn: 1) The relatively simple CIGR formula to calculate total...

What are the main environmental factors driving the development of the neurotoxic dinoflagellate Vulcanodinium rugosum in a Mediterranean ecosystem (Ingril lagoon, France)? ArchiMer
Abadie, Eric; Chiantella, Claude; Crottier, Anais; Rhodes, Lesley; Masseret, Estelle; Berteaux, Tom; Laabir, Mohamed.
Vulcanodinium rugosum, a dinoflagellate developing in Ingril Lagoon (Mediterranean, France) is responsible for shellfish intoxications due to the neurotoxin pinnatoxin G. A one year survey (March 2012–April 2013) was conducted in this oligotrophic shallow lagoon and key environmental parameters were recorded (temperature, salinity and nutrients). The spatio-temporal distribution of V. rugosum in water column and on macrophytes was also determined. Planktonic cells of V. rugosum were observed at all sampling stations, but in relatively low concentrations (maximum of 1000 cell/L). The highest abundances were observed from June to September 2012. There was a positive correlation between cell densities and both temperature and salinity. Non-motile cells were...

Intensification of rain-fed groundnut production in North Kordofan State, Sudan JARTS
Abdalla, Elgailani Adam; Aune, Jens B.; Osman, Abdelrahman K.; Idris, Aldaw M..
The main objective of this study was to evaluate intensification pathways for groundnut production in the marginal rain-fed environment of North Kordofan State, Sudan. The effect of intensification on yields was assessed in three different experiments. In the first experiment, the treatments were organised according to increasing level of intensification from the traditional production package to the improved production package (the ladder experiment). The complete improved package in the ladder approach consisted of increased density, new variety, seed priming, microdosing (0.6 g NPK per pocket) and mulching. Three levels of mulching and two levels of intensification constituted the second experiment (mulching experiment), while the third was an on-farm...

Accuracy and precision of phytonematode sampling plans CIGR Journal
Abd-Elgawad, Mahfouz Mohamed Mostafa.
Sampling accuracy and precision are basic to nematode research and rational management decision. Taylor's Power Law is used to determine sample size. The published power law parameters are used here differently to define levels of reliability associated with a fixed, cost-determined, sample size. Such levels may provide the decision-maker with more informative data on sampling methods and their reliabilities. Instead of solving for unknown sample number, the rearranged equation to solve for sampling accuracy permitted the use of exact Student’s t-values. The t-values for confidence limits and standard normal variate were used. Both statistical techniques resulted in identical confidence band, in terms of being below, at, or above the economic threshold...

Postharvest application with propolis for controlling white rot disease of green bean pods CIGR Journal
Abd-El-Kareem, Farid; Abd-Elgawad, Mahfouz Mohamed Mostafa; Saied, Nehal.
White rot is the most severe disease attacking green bean pods during pre and postharvest stages. Ethanol extracted propolis (EEP) at four concentrations i.e. 0, 5, 10 and 15% was tested to study its effect on growth inhibition zone of the causative fungus Sclerotinia sclerotiorum. Results indicated that all tested concentrations of EEP significantly increased the inhibition zone of S. sclerotiorum growth. The highest increase was obtained with at 15% where complete reduction in sclerotia germination occurred. At EEP 10%, the sclerotia germination was reduced by 91.6%.  When the same concentrations were tested to study their effect on white rot disease of green bean pods during storage, all EEP significantly reduced the percentage of white rot incidence...

Prediction Of Lateral Force In An Off-Road Tire As A Function Of Seven Variables Using Response Surface Methodology (RSM) CIGR Journal
Abdolmaleki, Hamid; Jafari, Ali; Mousazadeh, Hossein; Hajiahmad, Ali.
In this study an in-situ Single Wheel Tester (iSWT) was used to investigate the effect of some of the most important independent variables on the lateral force of a high lug agricultural tire. The variables include some soil parameters and tire characteristics. Response Surface Methodology (RSM) also was used to construct a design of experiment and propose the lateral force model as a function of seven variables (various combination treatments of soil characteristics and tire parameters). A total of 152 experimental tests were conducted to find appropriate model. Reduced form of a quadratic model was selected to predict the tire lateral force (R2 > 0.9). The results show that the side slip angle and moisture content had major and minimal effect on tire...

Here we report the discovery of two Tupanvirus strains, the longest tailed Mimiviridae members isolated in amoebae. Their genomes are 1.44?1.51 Mb linear double-strand DNA coding for 1276?1425 predicted proteins. Tupanviruses share the same ancestors with mimivirus lineages and these giant viruses present the largest translational apparatus within the known virosphere, with up to 70 tRNA, 20 aaRS, 11 factors for all translation steps, and factors related to tRNA/mRNA maturation and ribosome protein modification. Moreover, two sequences with significant similarity to intronic regions of 18 S rRNA genes are encoded by the tupanviruses and highly expressed. In this translation-associated gene set, only the ribosome is lacking. At high multiplicity of...
