Air Pollution Mapping with Bio‐Indicators in Urban Areas

Our study consists of the assessment and the mapping of the atmospheric pollution, which concerns the region of Tiaret city, by using the lichens as bioindicators. In our zone, we did a survey on 25 domains by using Kirschbaum and Wirth 1997 method. This method has enabled to define five classes according to the calculated air quality index (AQI). The dominant class was the one that contained a high pollution degree, which is reflected through the spatial distribution of the lichen species. The achieved map allows us to better visualize the pollution state

A hybrid algorithm to size the hospital resources in the case of a massive influx of victims

Disaster situations either natural or made-man caused a large number of deaths and injured people. Morocco has experienced several disasters recently, the last one was the railway accident on 16 October 2018, which caused 127 serious injuries and 7 deaths. This large number was a big problem for the hospital to manage the received victims in right direction, which caused lives lost and disability. In this article, in collaboration with Mohammed (V) hospital in Casablanca city in Morocco, we suggested a solution that saves lives and eliminates number of disability by using a hybrid algorithm to size the hospital resources in the case of a massive influx of victims. We also suggested a support decision tool that is called Emergency Support Decision Tool. This helpful tool gives an idea about the needed resources that support these emergencies according to the victim’s number. The proposed solution consisted in making a hybrid algorithm that mixed the theoretical simulation process and the experience feedback by developing hybrid genetic and hybrid heuristic algorithms. These algorithms using as an input the matrix solutions that generated under ARENA software and the solution generated by neural networks that based on experiences feedback. The objective was to provide a solution based on available resources. In fact, the results showed that the hybrid heuristic algorithm is more performant than the hybrid genetic algorithm

BIO-SURVEILLANCE DES METAUX LOURDS (PB, ZN, CU) A LA SORTIE DE LA STATION D’EPURATION DE TIARET (ALGERIE) AU MOYEN DES VEGETAUX AQUATIQUES: PLANTE LEMNA MINOR, ALGUE SPYROGYRA LINK SP ET BROYOPHYTE FONTINALIS ANTIPYRETICA

An original device has been developped and valided to monitor water quality with aquatic plants at the exit of wastewater treatment with plants in ain bouchakifin tiaret (algeria). This device or « bio-station » has provided first particularly interesting results: the selected bio-indicator plants (lemna minor ,spyrogyra link sp and fontinalis antipyretica) are able on one hand to grow in the effluents with a significant accumulation of heavy metals, and on the other hand to detect these micro-pollutants even when they are undectable in effluents. The results obtained during this study, have revealed severe contamination of purified wastewater with heavy metals specially lead, zinc and copper, the values recorded for pb are 29,17 ± 25,66 ug/g (spyrogyra link sp), 48,43 ± 39,07 ug/g (fontinalis antipyretica) et 16,78 ± 12,37 ug/g (lemna minor). The highest values were observed for copper and zinc accumulated by these plants for copper are: 275,93 ± 235,20 μg/g, 416,52 ± 285,88 ug/g and 213,92 ± 137,07 ug/g respectively. By against, the concentrations recorded for zinc are 917,04 ± 654,40 ug/g , 1040,48 ± 848,34 ug/g and 545 ± 368,76 g/g respectively. It therefore appears that a "bio-station" equipped sentinel plants sentinel can be an efficient and economical complementary device for continuously monitoring contamination waste water from treatment plants prior to their arrival at the dams

First Data On Amphibia Inventory And Distribution (Ordre Des Anoura) In Northwestern Algeria (Tiaret Area)

In the northwest of Algeria, we find the Tiaret area, which is characterized by a remarkable diversity of ecosystems, mainly composed of forests, scrub, cereal plain, steppe, a dune corridor, wetlands, Chott, Daya, dams, reservoirs of hill waters, ponds, wadis and cliffs. This diversity provides favorable and essential conditions for various species of amphibians that frequent this area with a semiarid climate. The present work aims to carry out an inventory of amphibians in the Tiaret region, as well as their distributions in these various ecosystems. We were able to inventory around 05 species of amphibians, distributed among 04 families and 01 order, distributed, in the different remarkable areas of the study region. Most of the species are frequent and abundant, cited in the bibliography (Pelophylax saharicus, Bufotes boulengeri, Sclerophrys mauritanica and Discoglossus pictus); except for one species (Hyla meridionalis), which is very rare in our study area

Climate Change Impacts Can Be Differentially Perceived Across Time Scales: A Study Among the Tuareg of the Algerian Sahara

Unidad de excelencia María de Maeztu CEX2019-000940-MAs an Indigenous community of Algeria and the broader Sahel, the Tuareg hold unique ecological knowledge, which might contribute to broader models of place-based climate change impacts. Between January and April 2019, we carried out semi-structured interviews (N = 23) and focus group discussions (N = 3) in five villages of the province of Illizi, Algeria, to document the local Tuareg community's timeline and ecological calendar, both of which are instruments used to understand place-based reports of climate change impacts. The livelihoods of the Tuareg of Illizi are finely tuned to climate variability as reflected in changes reported in the cadence of events in their ecological calendar (marked by cyclical climatic and religious events). Participants reported rain and temperature irregularities and severe drought events, which have impacted their pastoral and semi-pastoral livelihoods. These reports are aligned with scientifically measured climate observations and predictions. Paradoxically, although participants recall with detail the climatic disasters that happened in the region over the last century, the Tuareg do not explicitly report decadal trends in the frequency of extreme events. The differential perception of climate change impacts across scales can have important implications for undertaking climate change adaptation measures

Barriers to ICT Integration in Moroccan Secondary School EFL Classrooms

There is a broad consensus in the literature that the use of Information and Communication Technology (ICT) has become an effective tool that can be used for educational purposes. The use of ICT in the classroom creates better learning opportunities and enhances the quality of teaching. However, barriers to ICT integration hinder this process. The aim of this paper is to explore the perceived barriers to ICT integration that Moroccan secondary school teachers encounter in EFL classrooms. This study adopted a mixed-methods design, and data were collected through two instruments: a survey questionnaire and a semi-structured interview. Secondary school EFL teachers in the area of Agadir, Morocco, participated in this study and of the 80 informants who completed and returned the questionnaire, 8 of them were interviewed. The findings indicate that the major barriers that teachers encounter in integrating ICT into the classrooms were lack of adequate ICT facilities in the schools, lack of time, lack of continuous and effective ICT training, technical problems, and lack of technical support. Further, various solutions and recommendations are offered to minimize these barriers and maximize the beneficial use of ICT in the teaching and learning process in Moroccan EFL secondary school settings.

Analyse floristique de la végétation steppique dans la région de Djelfa, Nord-Ouest algérien

This study is a floristic investigation of the steppe region of Djelfa located in northern Algeria, with the aim of characterizing and analysing the wild flora of this region. Four stations were chosen according to a stratified sampling method and phyto-ecological surveys were carried out in 32 plots of 100m2 each. This allowed us to identify 127 taxa of plants belonging to 33 families dominated by Asteraceae (29%) and Poaceae (12%). The analysis of biological types has shown the dominance of annual Therophytes (56%) in this flora, which indicates the presence of the phenomenon of Therophytization in these regions. This phenomenon was also measured by calculating the perturbation index. The analysis of chorological types has shown the dominance of the Mediterranean element (48%), with an interesting number of endemic taxa. However, all the endemic taxa cited in the literature for this region have not been found, which reinforces our fears about the state of conservation of these taxa of biological and heritage value

Flore endemique, rare et menacees de l'Atlas Tellien Occidental de Tiaret (Algerie)

Cette étude vise la connaissance et la recherche des plantes endémiques, rares et menacées de l’atlas tellien occidental de Tiaret. Les recherches ont été guidées par les données existantes dans la littérature afin de retrouver les plantes endémiques et rares citées pour la région de Tiaret. Nous avons exploité nos données de terrain (287 relevés floristiques) ainsi que d’autres recherches ciblées afin de localiser les taxons endémiques. Cela nous a permis d’identifier 32 plantes endémiques (7 endémiques strictes Algérie; 11 Algérie-Maroc; 4 Algérie-Tunisie; 10 Afrique du Nord). Les recherches ont permis également de reconnaitre 36 taxons rares, 4 Trigger species et 17 taxons menacées (protégés). Plusieurs taxons cités dans la bibliographie pour la région n’ont pas été retrouvés ce qui laisse à s’interroger quant à l’état de conservation et l’existence de ces taxons dans un environnement très fortement perturbé par l’action anthropique dévastatrice

Flore endemique, rare et menacees de l'Atlas Tellien Occidental de Tiaret (Algerie)

This study is aims at the knowledge and research of endemic, rare and endangered plants of the Western Tell Atlas of Tiaret. The research was guided by data existing in the literature to find the endemic and rare plants cited for the region of Tiaret. We used our field data (287 foristic records) as well as other targeted research to locate endemic taxa. This allowed us to identify 32 endemic plants (7 strict endemic of Algeria, 11 of Algeria-Morocco, 4 of Algeria-Tunisia, 1O of North Africa). The research also identiied 36 rare taxa, 4 Trigger species and 17 threatened (protected) taxa. Several taxa listed in the bibliography for the region have not been found, which raises questions about the conservation status and the existence of these taxa in an environment that is highly disturbed by devastating human activity.Cette étude vise la connaissance et la recherche des plantes endémiques, rares et menacées de l’atlas tellien occidental de Tiaret.
