The present study records the first observation of a female Delta dimidiatipenne constructing its nest in Oran (NW-Algeria). The nest construction and developments thereafter were monitored every three days from July to September 2022 (70 days). Ultimately four female wasps were successfully emerged. This first record will be useful for future studies on the distribution, behaviour, ecology and conservation in this semi-arid region.

The present study evaluated the potential of Salvia balansae from the Aures Mountains as a source of natural bioactive compounds. Leaves, flowers, and stems were extracted separately using methanol, ethanol, and acetone. Phenolic compounds were quantified colorimetrically and identified using liquid chromatography coupled with mass spectrometry (LC-MS). Antioxidant capacity was assessed using six different in vitro assays, 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt, 1,1-diphenyl-1-picrylhydrazyl, cupric reducing antioxidant capacity, ferric reducing antioxidant power, ferrous ion chelating, and phenanthroline assay, while the photo-protective capacity was evaluated using the sun protective factor. The methanolic flower extracts revealed the highest O-diphenol and phenolic levels (287.9 ± 0.50 and 147.87 ± 0.21 µg GAE/mg, respectively), whereas the acetonic and ethanolic leaf extracts contained the highest flavonoid (72.17 ± 0.12 μg QE/mg) and flavonol (35.28 ± 0.05 μg QE/mg) levels, respectively. LC-MS was used to identify 18 phenolics, including quinic acid (5.051–69.69 ppm), luteolin-7-o-glucoside (7.802–44.917 ppm), apigenin-7-o-glucoside (3.751–68.507 ppm), and cirsiliol (2.081–15.608 ppm), distinguishing this Aures taxon. Principal component analysis and unweighted pair-group method with arithmetic mean revealed variability in phytochemicals, antioxidant properties, and photo-protective activity influenced by biological activities and the compound content. Overall, S. balansae demonstrated promising photo-protective capacity, the presence of key bioactive compounds, and wide-ranging antioxidant potential, presenting this endemic plant as a valuable source of natural antioxidants and photo-protective agents with pharmaceutical and cosmetic applications.

In August 2021, very intense fires swept through various forested areas in northern Algeria, particularly in Kabylia. The population dynamics of Cistus salviifolius and Cistus monspeliensis were studied along a post-fire successional gradient during the first nine months (September 2021 – May 2022), in two forest communities: the Cork oak (Quercus suber) and the Aleppo pine (Pinus halepensis) forests in the coastal zone of Bejaia province. The Cistus spp. germinations were counted monthly in each forest on 10 plots of 1 m2, evenly distributed along 2 transects of 45 m each. The results showed that the majority of germinations occur in December with 207.5 ± 24.2 seedlings in the Cork oak forest and 171.3 ± 18.0 seedlings in the Aleppo pine forest. Student’s t-test does not reveal significant differences for December between the two communities. During the first months following the fire (September and October 2021), germinations were almost absent. The monthly rainfall in September 2021 was estimated at 16.25 mm, an insufficient amount for effective germination. Late germination results in an extension of its period, showed a high rate in January 2022 with 42.2 ± 2.1 and 11.5 ± 0.8 seedlings, respectively, in the Cork oak forest and the pine forest. Beyond January, germination was practically nonexistent in both communities. Therefore, the majority of the seed germination was concentrated in November, December, and January with a unimodal germination pattern.

Salt resistance studies have, unfortunately, mainly been focused on conventional crops, with very few studies being conducted on the potential of available halophytes as new crops in the future. Portulaca oleracea L. has been listed as one of the most used medicinal plants by the World Health Organization as an edible halophyte. It is a fast-growing herbaceous annual with high nutritional relevance. The present work was designed to determine the effect of six soluble salts (NaCl, Na2SO4, KCl, CaCl2, CaCO3, and MgCl2) on germination of P. oleracea seeds. The effect of salinity was tested on final germination percentage (FGP%), and germination tolerance index (GTI%) using five concentrations (0, 200, 300, 400, and 600 mM) of each salt. In addition, laboratory experiments were conducted to assess the effects of salinity on germination recovery from high saline conditions (600 mM). Salinity level and salt composition significantly influenced germination attributes. P. oleracea seeds were non-dormant, exhibited approximately 100% germination in distilled water. Both FGP and GTI gradually decreased with increasing salinity. This study showed that seeds of P. oleracea can germinate under 300 mM in all tested salts. The salts causing germination inhibition exhibited specificity, with an increasing trend observed in the following sequence: MgCl2 > Na2SO4 > NaCl > KCl > CaCl2 > CaCO3. Transferring ungerminated seeds from 600 mM to distilled water recovered their germination ability. Based on these results, we can conclude that P. oleracea is a high salt-tolerant species that can tolerate a variety of salts found in soil. Therefore, P. oleracea may be considered a promising species for improving ecological balance in saline soils.

This study aims to update the list of Nitidulidae species observed on date palms in Algeria (Ziban region), their spatial dynamics according to the development stages (larva, pupa, adult), and the effectiveness of the bagging operation. In 2020, we sampled and examined 1800 dates of the Deglet Nour variety from three palm groves managed with different protection modes: yellow bagging, white bagging, and no bagging. The results obtained mention the presence of nine species of Nitidulidae with five species reported for the first time on dates in Algeria. The highest relative abundance (RA) of Nitidulidae beetles was noted in the southern (28%) direction. However, the variation of infestation rate (IR) according to the direction was not very accentuated. The GLM analysis showed that, except for the adult stage, the direction presented a highly significant effect on the RA variation of the total Nitudilidae, the larva and pupa stages (p < 0.0001), but there was no significant effect of direction on the IR in all studied cases. The highest RA of total Nitidulidae was found on the white plastic-protected dates (RA = 42%), the IR of the total Nitidulidae was higher on dates protected by yellow plastic (IR = 38%). The unprotected dates recorded the lowest RA and IR for all studied cases and the effect of bagging type on the RA variation of Nitidulidae, in all studied cases, was statistically highly significant (p < 0.0001). This effect on the IR was very highly significant only for total Nitudilidae, larvae, and adults (p < 0.0001). So, the southern direction presents the best conditions for sheltering the largest numbers of Nitidulidae. The latter also has a marked preference for bunches covered by plastic bags rather than for those left uncovered. This implies the ineffectiveness of the operation of protecting dates with plastic bags, especially the yellow-coloured ones.

Wetlands are present within intricate ecological settings, exhibiting dynamic changes over time and across different areas with regard to their functional and structural diversity. Several approaches have been introduced for ecosystem analysis and management since 1990s, where Driver – Pressure – State – Impact – Response (DPSIR) framework is one of the widely used approaches for assessing and managing environmental problems. In this study, we proposed a DPSIR framework as a model in the Sebkhates of Aures wetland complex (SAWC, Northeast of Algeria), in order to create a regional wetland observatory to deliver ecosystem services within current state of changes resulted from socioeconomic drivers. DPSIR facilitates the identification of essential indicators to detect threats to the Sebkahtes of Aures wetlands complex (SAWC), influencing policymakers to enhance the protection and management of these wetlands. In line with the established DPSIR framework. This same approach and methodology could be applied to the other 15 wetlands complexes known in Algeria, culminating in the creation of a national wetland observatory. Furthermore, DPSIR can be employed as an analytical tool for policy making in the context of sustainable management of wetland ecosystems and can serve as a model in the establishment and development of various observatory programs in Algeria.

Le présent article propose une étude portant sur l’œuvre « Simorgh » de Mohamed Dib. L’auteur nous présente une œuvre marquée par une ivresse moderniste et utopique sous une nouvelle forme qui escamote toutes les règles, pour offrir une hybridité, un éclatement, une fragmentation ; En somme une œuvre riche, tant au niveau de la forme qu’au niveau du fond. Sa construction apparemment erratique n’est en réalité que le signe, mais surtout l’appel à explorer sa richesse pluridimensionnelle, tel l’oiseau mythique dont l’esprit habite subtilement l’œuvre se donnant pour mission cette quête qui semble savoir intrinsèquement que ce que le cherche au dehors de soi est plutôt dedans.

Les pratiques langagières réalisées sur le web, en particulier sur les réseaux sociaux et précisément dans un espace techno-discursif algérien, connaissent une effervescence impressionnante. En effet, une accélération imposante est constatée dans les interactions en ligne. Toutes ces transformations sont le fruit de l’association de la machine et de l’outil informatique aux compétences langagières des internautes. Ces pratiques ont favorisé la possibilité d’aller très vite dans la communication en ligne, ainsi que dans la qualité du message produit qui est de plus en plus proche au message fait dans la communication ordinaire.Language practices carried out on the web, in particular on social networks and precisely in an Algerian techno-discursive space, are experiencing an impressive effervescence. Indeed, an imposing acceleration is observed in online interactions. All these transformations are the result of the association of machines and IT tools with the language skills of Internet users. These practices have favored the possibility of going very quickly in online communication, as well as in the quality of the message produced, which is increasingly close to the message made in ordinary communication.

Since 2011,Syria has witnessed a furious civil war that has resulted in a dangerous humanitarian crisis. Thousands of Syrians were obliged to leave Syria searching for a decent life.Some of these refugees succeeded in reaching their destination while others lost their lives.This paper seeks to investigate the representation of Syrian refugees in media discourse. More specifically, it aims to analysethe linguistic and discursive strategies employed by CNN andAl Jazeera in their representations of Syrian refugees through analyzing two articles published in 2015.It is a qualitative study that adopts Critical Discourse Analysis (CDA) drawing on the social discoursal framework of Norman Fairclough. The results revealed that there is no neutral representation, and that both channels dehumanized Syrian refugees by representing them as great masses of vulnerable people.

Enterprises have always given great importance to business process management to be competitive and profitable. With the advent of cloud computing, other opportunities are given to these enterprises to execute their business processes with minimal cost in a very short time. Business processes (BPs) are modelled using specific languages. BPMN is the most popular of these languages. However, its current version does not support process modelling for eventual execution in the cloud. Resource management, risk management, deployment, and security are key concepts in cloud computing that a modelling language must support. This paper presents an extension of the BPMN language for modelling business processes in the cloud, integrating the concept of security to secure cloud execution. The use of our new proposed architecture and models for secure BPs is illustrated by a real-life example that demonstrates how our extension is used to define/enforce actual security requirements.

La verbalisation métagraphique, inspirée des entretiens d’explicitation de Vermersch (1991) favorise la métacognition. En effet, le scripteur est conduit à réfléchir à la fois sur la langue écrite comme objet d’étude et sur son propre fonctionnement. Ceci nous conduit à nous demander : Quelle méthodologie mettre en place afin d’accompagner les scripteurs, à savoir des étudiants universitaires dans le retour réflexif sur le fonctionnement de la langue ? Partant de l’analyse de verbalisations métagraphiques menées avec lesdits étudiants, nous postulons à ce titre, que l’accent serait mis sur une méthodologie qui pourrait être transposée dans le milieu institutionnel et ce, afin d’aider les scripteurs à expliciter leurs cheminements cognitifs voire, leurs choix orthographiques. Abstract: The metagraphic verbalization, inspired by Vermersch's explanatory interviews (1991), promotes metacognition. Indeed, the writer is led to reflect both on the written language as an object of study and on its own functioning. This leads us to ask ourselves: Which methodology should be set up to accompany the writers, namely university students, in the reflective feedback on the functioning of the language? Starting from the analysis of metagraphic verbalizations conducted with these students, we postulate that the emphasis would be placed on a methodology that could be transposed in the institutional environment in order to help writers to explain their cognitive processes or even their spelling choices.

Notre article est une étude littéraire qui s’articule autour d’une composante importante du texte littéraire ; le personnage romanesque. Ce concept que nous allons explorer dans trois textes : le Festin Nu de William Burroughs. La Morsure du Coquelicot de Sarah haidar, et Archéologie du Chaos (amoureux) de Mustapha Benfodil. Notre étude vise à rechercher le lien intertextuel, en l’occurrence le personnage révolté, entre les trois romans. Plusieurs renvois dans les deux textes algériens au texte américain, nous ont poussé à s’interroger sur ce lien qui pourrait les rassembler. Cette étude va être à la lumière des théories faites par Roland Barthes et Kristeva sur l’intertextualité, aussi les travaux de Philippe Hamon et Vincent Jouve sur le personnage romanesque.

Agriculture is a crucial element to build a strong economy, not only because of its importance in providing food, but also as a source of raw materials for industry as well as source of energy. Different diseases affect plants, which leads to decrease in productivity. In recent years, developments in computing technology and machine-learning algorithms (such as deep neural networks) in the field of agriculture have played a great role to face this problem by building early detection tools. In this paper, we propose an automatic plant disease classification based on a low complexity convolutional neural network(CNN)architecture, which leads to faster on-line classification. For the training process, we used more than one 57,000 tomato leaf images representing nine classes, taken under natural environment, and considered during training without background subtraction. The designed model achieves 97.04% classification accuracy and less than 0.2 error, which shows a high accuracy in distinguishing a disease from another.

Le présent article met en jeu un objectif bien précis, celui de nous interroger sur le rôle des questions argumentatives et de cerner leurs relations avec l’évolution argumentative des thèmes mis en délibération onusienne. Le corpus d’analyse est un recueil de comptes rendus analytiques « textes officiels » qui ont été récoltés sur le site officiel des Nations Unies. Notre travail s’inscrit dans la conception de l’interaction argumentative telle qu’elle a été définie par Christian Plantin. Ce modèle s’accorde parfaitement avec une analyse du dialogue onusien. Dans ce travail nous visons à présenter le statut argumentatif et interactionnel de la question argumentative. This article brings in a very precise objective that allows us to interrogate the role of argumentative questions, and to identify their relations with the argumentative evolution of themes provided in the United Nations’ deliberation. The corpus of analysis is a collection of analytic reports “official texts”, which were collected from the UN’s official website. Our work falls under to the conception of argumentative interaction such as the one defined by Christian Plantin. This model corresponds perfectly with the UN’s dialogue analysis. In this work, we aim to present the argumentative and interactional statuses of argumentative questions.

An effective Food Traceability System (FTS) in a Food Supply Chain (FSC) should adequately provide all necessary information to the consumer(s), meet the requirements of the relevant agencies, and improve food safety as well as consumer confidence. New information and communication technologies are rapidly advancing, especially after the emergence of the Internet of Things (IoT). Consequently, new food traceability systems have become mainly based on IoT. Many studies have been conducted on food traceability. They mainly focused on the practical implementation and theoretical concepts. Accordingly, various definitions, technologies, and principles have been proposed. The “traceability” concept has been defined in several ways and each new definition has tried to generalize its previous ones. Nevertheless, no standard definition has been reached. Furthermore, the architecture of IoT-based food traceability systems has not yet been standardized. Similarly, used technologies in this field have not been yet well classified. This article presents an analysis of the existing definitions of food traceability, and thus proposes a new one that aims to be simpler, general, and encompassing than the previous ones. We also propose, through this article, a new architecture for IoT-based food traceability systems as well as a new classification of technologies used in this context. We do not miss discussing the applications of different technologies and future trends in the field of IoT-based food traceability systems. Mainly, an FTS can make use of three types of technologies: Identification and Monitoring Technologies (IMT), Communication Technologies (CT), and Data Management Technologies (DMT). Improving a food traceability system requires the use of the best new technologies. There is a variety of promising technologies today to enhance FTS, such as fifth-generation (5G) mobile communication systems and distributed ledger technology (DLT).

In this paper, we present a novel hybrid meta-heuristic by enhancing the Basic Bees Algorithm through the integration of a local search method namely Simulated Annealing and Variable Neighbourhood Search like algorithm. The resulted hybrid bees algorithm (BASA) is used to solve the Single Machine Scheduling Problem with Early/Tardy jobs, where the generated outcomes are compared against the Basic Bees Algorithm (BA), and against some stat-of-the-art meta-heuristics. Computational results reveal that our proposed framework outperforms the Basic Bees Algorithm, and demonstrates a competitive performance compared with some algorithms extracted from the literature.

The aim of this paper is to propose a new family of codes.  We define this family over the ring R=∑4s=0vs5A4R=∑s=04v5sA4, with v55=v5v55=v5.  We derive its properties, a generator matrix and Gray images.  This new family of codes is illustrated by three applications.

From the 1990s, urban policy in Algeria underwent significant upheavals, including authoritarian management, which was replaced by participatory management. Following the example of Algerian cities, the city of Batna adheres with this new vision, hence the implementation of a partnership program that involves various stakeholders including the citizen. The latter is present within multiple associations. The objective of this work is to highlight the activism of neighborhood associations as a representative element of civil society and their determining role in the management of different situations. To report on this issue, a field survey was conducted in the form of semi-directive interviews addressed to the three local actors: associations, citizens and elected officials.
