three communicable diseases (Brucellosis, Tuberculosis and Foot-and-Mouth Disease) in the
district of Souk Ahras in north-eastern Algeria, between November 2015 and June 2016.
Obtained results on tuberculosis and brucellosis during the year of 2015 showed No significant
difference in the suspected mean annual frequencies by veterinarians and those reported by the
DSA of Souk Ahras district, with 5.37% for Tuberculosis and 2.50% for Brucellosis. Only FMD
with a frequency of 4.58% was significantly different, where the frequency reported by
veterinarians was higher than that reported by the DSA.Diplôme : Magistère En ligne : ../theses/veterinaire/REZ7029.pdf Format de la ressource électronique : Permalink : https://bu.umc.edu.dz/md/index.php?lvl=notice_display&id=10570 Contribution a l’etude de la frequence et de la repartition des principales maladies bovines a declaration obligatoire dans la wilaya de Souk Ahras.

have information on the risk coming from the phenomenon of resonance. We hope to contribute in this area of
vibration this insufficiency which is based on the background and investigation in this area using energy method.
The dynamic analysis of strategic elements of thin rectangular isotropic and orthotropic plates with various
conditions limits was considered. This study was reinforced by addition a load uniformly distributed and a hole on
the isotropic thin plates.
In this work we develop a good program using mathematical software “MAPLE” , to investigate dynamic
behavior of rectangular plate with various conditions limits. The development and solutions of free dynamic
behavior are use as responses factors and obtained based on Rayleigh-Ritz. To enhance the possibility of the
developed program in performing dynamic analysis, we use many type of shapes functions consistent with the usual
boundaries conditions, and based on trigonometry or polynomial parameter, or with combination of both one. To
test the good performance of those selected shape functions, we compare the frequencies solutions calculated from
the program with those obtained from literature. Using the same steps as indicated from the literature and then
performing the dynamic analysis based on those combinations and lead to response within good tolerances. Others
investigations are performed to certify the performance of the program from one hand, and then open new
perspectives about the capability to handle the dynamic behavior analysis, concerning rectangular plates subjected
to some assumptions, that is:
1. A study on parametric frequency for dynamic analysis of rectangular isotopic thin plate with different
combinations of boundaries conditions (SSSS, SCSS, SCSC, CCSS, CCCS, CCCC, CSSF, CSCF,CCSF,
SCSF,CSFF, SSSF).
2. A study on parametric frequency for dynamic analysis of rectangular orthotropic thin plate with different
combinations of boundaries conditions (CCCC,SSSS,SSCC,SCSC,CFCC,SFSS).
3. Effect of distributed load on the free dynamic behavior of rectangular thin plate
(SSSS ,SSCC,SCSC,SSCS,CSCC,CCCC).

Biologie Résumé : Overweight and obesity in adolescence often persist into adulthood and it’s accompanied by risks of increased morbidity and mortality in patients being overweight or obese in adolescence.
A cross-sectional study with single elementary sampling nominative list of all college students enrolled in the academic year 2012/2013 has allowed us to estimate the frequency of overweight and obesity in teenagers of Constantine. For that 457 teenagers were recruited.
The frequency of overweight and obesity according to the 2007 WHO reference z-score, is respectively 18.2% and 13.2%, including 1.8% with severe obesity. Overweight and obesity are more prevalent in boys than in girls. Obesity is more common among adolescents who don’t respect the main meal of the day and those who don’t take their family meals. The obese have low nutritional knowledge and less physical activity compared to leans ones. Birth order may be identified as a risk factor. Obesity is more common among adolescents who have
parents with a higher socio-economic and socio-professional status. Breast feeding plays an essential role in the prevention of overweight in childhood and adolescence. Birth weight would influence the weight at the age of 5 and 10 years and at adolescence, anxiety of obese adolescents associated with poor felt the denial of the image of their own body size may increase overweight and obesity among these. Puberty is a critical period in the development of obesity.
The genotype of CD36 gene lingual, rs1761667 (AA) could be responsible for the low
detection of lipids and encourage teenagers to over-consume fat to have the same appreciation that subjects with the other two AG and GG genotypes.
Obesity in adolescence seems to play an important role in predicting very slight increase in glucose and lipid values, insulin and inflammatory, confirming the deleterious role of excess weight on biological data.
Through measures as dietary and behavioral, we can fight effectively against long-term obesity in adolescents.

CD والاقتصادي و الجين 36Index. décimale : 570 Sciences de la vie. Biologie Résumé : This study aims at determining the incidence of overweight and obesity in children aged, from 7 to 8 years, attending school in the town of Constantine, with a follow-up for three years 2009-2010, 2011-2012 and 2012-2013.
The determinants of obesity are multiple and complex interactions. Beyond the individual biological or genetic factors that can not be ignored, obesity is primarily the result of an energy imbalance but this imbalance is strongly influenced by the child's environment, as well as early throughout the life.
We have also characterized in a second part of the risk factors associated with overweight. The third objective of this thesis was to investigate a relationship between fat taste and weight. Whether the oral sensitivity, in the obese, to oleic acid and normal weight children was the same. In other words, if they had the same fat taste detection thresholds or if this threshold was altered in obese children. There was a significant correlation between
age and childhood obesity.
The low level of education, corpulence of the parents, macrosomia seem to play an important role in the development of childhood obesity. Although the difference was not significant, obesity is more common in children with artificial feeding. Obese children are more sedentary compared to normal weight.
Obese children took less often breakfast compared to normal weight ones. They also tended to take more snacks in the evening and throughout the day with high energy density foods. All children consumed foods high in fat, grains, starches, meats and fish and soft drinks during lunch and dinner.
Obese children appear to have a significant reduction (40 times) in the gustatory perception of fat taste. These differences in taste sensitivity may be the result of polymorphism of CD36 gene. Early preventive actions, therefore, are necessary to stop and, if possible, reverse the progression of overweight/obesity.
