From centuries, many incidents happened in the ocean shipping that have mostly condemn the water sear with harmful substances that pollute the marine fauna. And with the coming evolution into the ships size, the challenges that concern the Marpol contamination is constantly increasing. Conventions and legislations in that concern have put many actions for that issue, in order to stop disease of ocean ecology and maintain its sustainability. This paper seeks to review the topic of Sustainable development and its impact on the different phases of moving the Classic logistics into the green logistics within the maritime industry.

Soil characteristics and crop maturation are some of the most important factor that determined the engineering properties of agricultural products. In this study, the mechanical properties of plantain (Musa paradisiaca) fingers were determined under two soil treatment conditions and five maturity stages. The plantain plants were cultivated under two soil treatment methods, which were organic and inorganic treatments. The results revealed that soil condition had significant (P ≤0.05) effect on all the mechanical parameters investigated. The findings of the study revealed that the mechanical parameters of the organic produced plantain fingers were higher, when compared to the mechanical properties of fingers produced with inorganic soil treatment. The results further displayed that there were increment in the mechanical behaviours of the plantain fingers, as the maturation period increased from maturity stage 1 to maturity stage 3, before they started to decline to maturity stage, irrespective of the soil treatment applied. According to the results plantain fingers harvested matured but unripe (stage 3) can withstand the postharvest operations. Data obtain from this study will help engineers in designing and fabrication of systems for the mechanization of plantain production.

Objective: Describe the characteristics of patients admitted to the otolaryngology emergency department for an episode of epistaxis and analyze epidemiological, clinical, endoscopic data between the two groups in order to establish a model that predicts the risk factors associated to epistaxis. Methods: prospective study including 161 adult patients spread over a month in the department of otolaryngology; interesting two groups; patients who had epistaxis (group 1) and those who had another emergency (control group = group 2) in the same study period .A comparison was made of age, sex, time of consultation, surgical or traumatic history, taking medication (anticoagulants, nasal corticoids), hemodynamic parameters at admission (blood pressure, pulse, hemoglobin). Intergroup variations were analyzed using t student and chi-square tests. Univariate and multivariate logistic regression were used to establish a predictive model of occurrence of epistaxis. Results: Univariate logistic regression confirmed that the occurrence of epistaxis was associated with male gender, consultation during the night, an history of High Blood pressure (BP) or Coagulopathy, a high Mean systolic BP, a high Mean diastolic BP, high Cardiac frequency or a low Hemoglobin level at admission. According to the multivariate logistic analysis, the predictive factors of epistaxis despite were: male gender (OR =0.089, 95% CI [0.008-0.978], p = 0.048), history of high blood pressure (OR = 0.009, 95% CI [0.00-0.236], p = 0.005). Furthermore, the multivariate analysis excluded the effect of age, history of cardiovascular disease, or anticoagulants. Conclusion: The only predictive factors of epistaxis were male gender, and arterial Hypertension.

Demand for freight to be transported by road increases in many countries, around the world. Consequently, we should determine an interval of vehicle velocities of minimal dynamic effects on a mixed bridge. For this, we describe the dynamic behavior of the type vehicle 12-b on the steel-concrete bridge by combining the model equations of bridge, apron and vehicle and propose a framework in which the overall model equations is solved using the newmark method. In this approach, a criteria of limited deformation on the mixed bridge is required from eurocode 4 to examine the vehicle velocities that lead to minimal dynamical effects. The sensitivity analysis is experimented and this provides a number of admissible velocities of the type vehicle 12-b that satisfies the requirements of our steel-concrete mixed bridge. This type of operation is of great importance in the monitoring of a bridge at the stages of its design, construction or maintenance. Monitoring is an essential step prior to any other management action, and in the context of this monitoring, the measurements represent important issues. This is particularly true for the two special surveillance actions, which are enhanced surveillance and high surveillance; in the latter case, measurements on structures even constitute an essential condition for the very existence of high-level surveillance, because they alone are capable of giving precise information in real time on the unfavorable development of a structure.
