The current investigation is centered on the characterization of specific apple cultivars in the Garza region, within the Teniet El Abed municipality, situated 55 km east of Batna (NE-Algeria). Utilizing descriptors outlined by UPOV 2015 pertaining to apples, the study focuses on morphological parameters of leaves, fruits, and terminal shoots across three varieties: Golden Delicious, Royal Gala, and Starkrimson. Additionally, soil analysis was conducted to ascertain its suitability for apple cultivation. The examination revealed limited morphological diversity among the investigated apple cultivars, with some descriptors, particularly those related to fruit traits, showing insignificant differences between cultivar types. Overall, the studied varieties - Golden Delicious, Royal Gala, and Starkrimson - exhibit distinct physiological and morphological characteristics. Variations in size, shape, skin color, flesh attributes, as well as sugar and acid content, contribute to the uniqueness of each variety. Whether one prefers sweet or tart apples, or favors larger or smaller fruits, there exists an apple variety to cater to individual tastes. Our findings complement molecular analyses and underscore the need for further exploration of apple germplasm, alongside sustained conservation efforts.

Ilex aquifolium L. is an endemic species in Algeria’s Tellian and Saharan Atlas mountains in the country’s center and east, and it is on the verge of extinction owing to a variety of reasons. To help preserve it, we devised an in vitro micropropagation technique. The cuttings with axillary buds were cultured on different media supplemented with different combinations and concentrations of plant growth regulators. The best results were obtained on Woody Plants Medium (WPM) supplemented with 6-benzylaminopurine (BAP: 1.5 mg/LL, 3 mg/L) and naphthalene acetic acid (NAA: 1.5 mg/LL) in combination with BAP (1.5 mg/ L); BAP (1.5 mg/ L) with Gibberellins (GA3: 0.5 mg/ L). The best shoot proliferation rates were obtained on WPM supplemented with 1.5 mg/LL (BAP) and BAP: 1.5 mg/L; GA3: 0.5 mg/L; or BAP: 1.5 mg/L + ANA: 1.5 mg/L. The highest rooting rate (100%) was obtained with shoots grown on WPM medium supplemented with NAA (1.5 mg/LL). Absence of routing formation was observed in media containing indolacetic acid (IAA: 1 mg/ L) alone or combined with BAP: 0.5 mg/ L) The best-rooted shoots must be acclimatized to a substrate consisting of a mixture of peat and sand (1:1 v/vv), the seedlings have been acclimatized successfully.

Honey has a long history of use in many cultures as food and medicine. It is a food of animal origin closely linked to the territory, due to honeybees need the flora to obtain the honey. Melissopalynology plays a significant role in the identification of the distinctive food print of honey throughout its pollen content, being essential for guaranteeing origin. Algeria is the largest country in North Africa and possesses a diversified territory with different ecosystems that host wide plant biodiversity. Apiculture relies heavily on the pollination of plant species and the conservation of biodiversity, but also is a good source of economic income in rural areas. In Algeria, knowledge about plant resources for honey bees and the properties of the honey is raising interest. In this context, this chapter aims to provide a comprehensive overview of the different ecosystems of Algeria, the main pollen types found in the pollen spectra of honey and the principal honey types described.

 Daboia mauritanica (Gray, 1849), Moorish Viper, is native to North Africa. We update the distribution map for this species in Algeria, providing 19 new locality records, filling distribution gaps and significantly expanding the species’ known range. Our updated distribution map reveals a widespread presence of the species in northern Algeria, extending south into the northern Sahara. We note that some historical records in certain provinces remain unconfirmed and/or questionable, indicating the need for further investigation. Our findings underscore the importance of collaboration between researchers and citizen scientists in Algeria.

Aphids cause biotic stress and vector diseases. However, wheat’s morphological and biochemical responses to aphid infestation are poorly studied. Our study evaluated the varietal behavior of durum wheat (Triticum durum Desf) against Rhopalosiphum maidis (Homoptera: Aphididae) in laboratory conditions. We studied morphological trait variation (plant height [HP], flag leaf area [SFDF], leaf area [SF], spike length [LE], and beard length [LB]) and biochemical characteristics (chlorophyll, soluble sugars, and proline contents) of three varieties in Algeria: MBB, BOU, and GTA. MBB is the least affected, with a 13.34 % infestation rate. The heaviest infestation occurs during the heading stage. All morphological factors decreased in length or surface between control and infested samples. ANOVA showed significant variations for HP, LE, SFDF, and SF but not LB. Biochemical parameters decrease in GTA. In MBB, chlorophyll and soluble sugars decrease while proline increases. For BOU, soluble sugars decrease while chlorophyll and proline increase. Only soluble sugars showed a significant statistical variation between control and infested plants. HP is affected by aphid infestation, which is of higher significance for MBB. Proline content is affected in BOU and GTA. There is no significant variation between aphid infestation and chlorophyll, soluble sugars, and proline levels for MBB. The effect of R. maidis infestation is less important on MBB. HP, SFDF, SF, and LE are morphological selection criteria for R. maidis infestation resistance. Proline is a biochemical selection criterion. Genetic and molecular analyses are required to identify genes for programs that enhance durum wheat’s resistance to R. maidis infestations.

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.

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.
