Wings of a Rhodnius specimen from Alto Beni (Bolivia) was examined for identification and compared with R. stali, R. robustus, (certified Bolivian species), R. pictipes and R. prolixus (suspected Bolivian species). A projection of the unidentified wings as supplementary data into a discriminant analysis of shape revealed clear cut differences with R. stali and R. pictipes, less differences with...

s: The agriculture plays an important role in the Moroccan economy. The cereal culture occupies a place excellence in the farming sector. Cereals are essentially represented by the cultures of the wheat and the barley.The farmers meet several obstacles which accompany them during all the season and which can cause dramatic losses. The difficulty of the estimation of these losses by the farmers ...

This paper presents a type-2 fuzzy rule based expert system to handle uncertainty in complex problems such as portfolio selection. In a type-2 fuzzy expert system both antecedent and consequent have type-2 membership function. This research uses indirect approach fuzzy modeling, where the rules are extracted automatically by implementing a clustering approach. For this purpose, a new cluster an...

This paper presents a thorough experimental analysis to investigate the behavior of neural network classifier for classification of multispectral satellite images. For this series of experiments have been performed to study the effect of various neural network parameters upon classification accuracy. It is per pixel supervised classification using spectral bands (original feature space). The pa...

The Possibilistic C-Means clustering algorithm, in its original form, is not very suitable for clustering due to the undesirable tendency to create coincident clusters and to converge to a “worthless” partitions in the case of poor initializations, but it provides robustness to noise and intuitive interpretation of the membership values. Recently, an extension of the PCM has been presented by T...

Interpretation of aerial images is an important task in various applications. Image segmentation can be viewed as the essential step for extracting information from aerial images. Among many developed segmentation methods, the technique of clustering has been extensively investigated and used. However, determining the number of clusters in an image is inherently a difficult problem, especially ...

Individual differences in working memory capacity (WMC) typically predict reduced rates of mind-wandering during laboratory tasks (Randall, Oswald, & Beier, 2014). However, some studies have shown a positive relationship between WMC and mind-wandering during particularly low-demand tasks (Levinson, Smallwood, & Davidson, 2012; Rummel & Boywitt, 2014; Zavagnin, Borella, & De Beni, 2014). More sp...

American foulbrood (AFB) is one of the most destructive diseases of the honey bee. This infectious disease causes a great economic loss in beekeeping industry worldwide. This severe brood infection is caused by the spore forming bacterium, Paenibacillus larvae subspecies larvae White (formerly: Bacillus larvae subsp. larvae). AFB was not detected in Egypt till about two years, however the disea...

This technology describes the introduction of livestock refuge mounds in the sub-Amazonian eco-region of Bolivia (Department of Beni) as a good practice to increase the resilience of cattle raisers to recurrent floods. Livestock refuge mounds are small mounds covering an area of about 0.5-1 ha, and they provide shelter for people, livestock and agricultural products during floods. In addition, ...

Due to their toxicity, long persistence, bioaccumulative nature, and biomagnification in the food chain, heavy metals pose a serious hazard. The aim of this study was evaluate health risks associated with consumption Sardina pilchardus (Walbaum, 1792) spatiotemporal dynamics four potentially toxic metallic elements. Three hundred sixty specimens sardine were collected between December 2020 Octo...
