AIM:To report the results of a medical management of sphincter of oddi dysfunction(SOD) after an intermediate follow-up ***:A total of 59 patients with SOD(2 men and 57 women,mean age 51 years old) were included in this prospective *** medical treatment for one year,the patients were clinically re-evaluated after an average period of 30 ***:The distribution of the patients according to the Milwaukee's classification was the following:11 patients were type 1,34 were type 2 and 14 were type *** patients underwent an endoscopic sphincterotomy(ES) after one year of medical *** median intermediate follow-up period was 29.8 ± 3 mo(3-72 mo).The initial effectiveness of the medical treatment was complete,partial and poor among 50.8%,13.5% and 35%,respectively,of the *** the end of the follow-up period,37 patients(62.7%) showed more than 50% *** rate of improvement in patients who required ES was not significantly different compared with the patients treated conservatively(64.2% vs 62.2%,respectively).CONCLUSION:Our study confirms that conservative medical treatment could be an alternative to endoscopic sphincterotomy because,after an intermediate follow-up period,the two treatments show the same success rates.

New LMI Conditions for Reduced-order Observer of Lipschitz Discrete-time Systems: Numerical and Experimental Results

引用

International Journal of Automation and computing 2019年第5期16卷 644-654页

作者： Noussaiba gasmi Assem Thabet mohamed Aoun Research Center for Automatic Control of Nancy CRAN-CNRS UMR 7039University of LorraineCosnes et Romain 54400France Modeling Analysis and Control of Systems(MACS)LaboratoryNational Engineering School of GabesUniversity of GabesGabes 6072Tunisia

The objective of this paper is to propose a reduced-order observer for a class of Lipschitz nonlinear discrete-time *** conditions that guarantee the existence of this observer are presented in the form of linear matrix inequalities(LMIs). To handle the Lipschitz nonlinearities, the Lipschitz condition and the Young′s relation are adequately operated to add more degrees of freedom to the proposed LMI. Necessary and sufficient conditions for the existence of the unbiased reduced-order observer are given. An extension to H_∞ performance analysis is considered in order to deal with H_∞ asymptotic stability of the estimation error in the presence of disturbances that affect the state of the system. To highlight the effectiveness of the proposed design methodology, three numerical examples are considered. Then, high performances are shown through real time implementation using the ARDUINO MEGA 2560 device.

This study aims to assess the small ruminant value chain in Al-Ruwaished District,Jordan,to identify the potential intervention areas that could improve the production efficiency and guarantee the sustainability of the small ruminant sector in this *** breeding is the source of livelihood for most of the people in Al-Ruwaished District,which is characterized by the large number of sheep and *** surveyed 5.0% of the small ruminant holders in the study area and conducted individual interviews and surveys with the potential actors in the value chain to undertake a small ruminant value chain *** the survey,we found that the small ruminant value chain consists of five core functions,namely,input supply,production management,marketing,processing,and *** the stable impression given by the large number of holdings in the small ruminant sector,the surveyed results show a clear fragility in the value chain of small ruminants in this *** small ruminant production system is negatively impacted by climate change,especially continuous *** addition,the high prices of feed that the farmer cannot afford with clear and real absence of the governmental and non-governmental support activities also impact the development of the value *** results of strengths,weaknesses,opportunities,and threats(SWOT)analysis reveal that the major constraints faced by this value chain could be divided into external and internal ***,the most prominent external threats are the nature of the desert land and continuous drought,while the major internal threats are the absence of appropriate infrastructure,shortage of inputs,and weakness in the production management and *** proposed solutions to these challenges to ensure the sustainability and effectiveness of the sector,such as the formulation of emergency response plans to severe weather,qualifying farmers’skills,and establishment of agricultural cooperative societies.

Groundwater Protection Using DRASTIC Vulnerability Maps and ArcFem Tools for Perimeter Protection: A Case Study in the Charf El Akab Aquifer (Morocco North)

引用

International Journal of Geosciences 2018年第6期9卷 289-307页

作者： Moulay Lhassan Sadiki Lhoussaine El Mezouary Abdelaziz Khomsi Badr Benseddik El Houssine El gasmi mohamed El Bouhaddioui Malika Kili Jamal Chao Bouabid El Mansouri Aicha Benmohammadi Geosciences of Natural Resources Laboratory (GeoNaRes) Hydroinformatique Section Faculty of Science Ibn Tofail Univer-sity Maamora Campus Kenitra Morocco Laboratory of Analyse Mathématiques Géométrie Non-Commutative et Applications Faculty of Sciences Ibn Tofail Univer-sity Maamora Campus Kenitra Morocco Laboratory of Agrophysiology Biotechnology Environment and Quality Faculty of Sciences Ibn Tofail University Maamora Campus Kenitra Morocco

The Charf El Akab aquifer has a surface area of 17 km2 and is located about 20 km southwest of the Tangier city, it circulates in the Miocene sandy basin of the same name and comprises two layers, one high and the other low, these two are separated in some places by an airtight impenetrable sand-marly formation. The requirements for water whether potable or industrial, in the Tangier-Asilah region are expected to amplify in order to support the increasing demand prompted by the economical development, population growth as well as the heightened threat of scarcity related to climate change. Currently, the water supply of this region is ensured mostly by the two dams: Ibn Battouta and “April 9, 1947”. However, this aquifer plays the role of an easily usable emergency reservoir, in case of an extra water supply in rush hour or in the event where current service works of the cities of Tangier and Asilah are unavailable. Nevertheless, water resources are still vulnerable because of the existence of abandoned quarries in the area. Therefore, the protection of this aquifer against any source of pollution is the purpose of this work. The lower water layer is the only one that can be exploited by the ONEE (National Office for Electricity and Drinking Water), due to the fact that it has a better quality and very good hydrodynamic characteristics. The most important thing about this work is the establishment of an intrinsic vulnerability map to the pollution by the DRASTIC method, by exploiting of the calibrated hydrodynamical model results. In the same context of protection, a guesstimate of the close protection perimeter of 72.76 ha was acquired, using a new numerical modeling approach by the “Arcfem” software under the ArcMap environment.
