A New Stegano-Watermarking Scheme for the Creation of Medical Image Datasets
Boureima Koussoube, Moustapha Bikienga, Telesphore Tiendrebeogo, Cheick Yacouba Rachid Coulibaly
Digitisation of medical images is improving diagnosis and clinical research, but poses major challenges in terms of security and traceability. This paper proposes a hybrid solution combining digital watermarking and steganography to securely trace these images, while enabling automatic watermarking detection via adapted neural networks. We eva(...)

Effect of cooking technologies on the micronutrient and antioxidant content of Vigna radiata seeds
Mahamadi Hamed Ouédraogo, Yssouf Karanga, Rémy K. Bationo, Moumouni Koala, Éloi Palé
The actual nutrient content of legumes needs to be examined in detail. Indeed, the various mechanisms involved in preparing dishes for human consumption can affect the nutritional value and bioavailability of nutrients such as phenolic compounds, carotenoids and mineral elements. Vigna radiata varieties rich in bioactive compounds were selecte(...)

Functionalization of Arabic Gum by Both Oxidation and Acylation: Application as Sensing Materials for the Electrochemical Determination of Phenolic Compounds
Ousmane Ilboudo, Serge Foukmeniok Mbokou, Yssouf Karanga, Yibor Fabrice Roland Bako, Issa Tapsoba, Ignas Kenfack Tonlé
Novel functionalized Arabic gums (AGs) were obtained by oxidation and acylation
reactions on raw Arabic gum. The synthesized materials were used as
modifiers of carbon paste electrodes for the determination of quercetin (QCT),
rutin (RUT) and both p-aminophenol (PAP) and acetaminophen (APAP) in
0.1 M phosphate buffer solution (PBS), pH 6.0(...)

The role of non-timber forest products in reducing rural poverty in Burkina Faso
Ouedraogo, I., Maiga, E., & Esbjerg, L
Using data collected in 2023 on five hundred and thirty (530) randomly selected rural households in two regions of Burkina Faso, this research investigates the contribution of Non-Timber Forest Products (NTFP) exploitation to rural poverty reduction using two different approaches. Firstly, it considers NTFP income as an "exogenous transfer", w(...)

Implications psycho-affectives des attaques terroristes sur les conduites addictives des élèves déplacés internes des Bnwa
RAMDE Koudregma Cément, BARRY Aboubacar
Les attaques terroristes au Sahel ont provoqué un déplacement massif de populations, créant des communautés de déplacés internes, notamment dans la Boucle du Mouhoun au Burkina Faso. Cette étude se penche sur l'impact psycho-affectif de ces événements sur les élèves déplacés internes, en particulier sur leur consommation de substances psychoac(...)

Effets de la qualité des institutions sur la diversification des exportations intrarégionales en Afrique subsaharienne
Kisito Jean de Dieu Ouédraogo, Windkouni Haoua Eugenie Maïga et M. Idrissa Ouédraogo
La présente étude a pour objectif d’évaluer les effets de la qualité des institutions sur la diversification des exportations
intra-régionales en Afrique subsaharienne. Pour ce faire, nous avons utilisé des techniques économétriques efficaces
sur des données de panel, à savoir la méthode du Pooled Mean Group (PMG) développée par Pesaran, Shi(...)

Economic Dependence of Rural Households on Non-Timber Forest Products in Burkina Faso
Issoufou Ouédraogo, Windkouni Haoua Eugénie Maïga, Lars Esbjerg
Using data collected in 2023 from 530 randomly selected rural households in two regions of Burkina Faso, statistical analysis and Cragg (1971) model specifications, the present research analyzes the economic dependence of rural households on non-timber forest products (NTFPs). Unlike previous works, this article focuses solely on NTFPs derived(...)

The effect of natural resource dependence on industrialization in Africa: The role of institutional quality
Piman Alain-Raphael Bayili & Windkouni Haoua Eugénie Maïga
This article analyzes the role of institutional quality in the effect of natural resources on industrialization in Africa. Two industrialization indicators are considered: Manufacturing value added as a percentage of GDP and manufacturing value added per capita. An Autoregressive Distributed Lag model and the Pooled Mean Group (PMG) method are(...)

New Robust Watermarking Scheme for a Distributed Database with Hyperbolic Structure
Boureima Koussoube, Moustapha Bikienga, Telesphore Tiendrebeogo
In this paper we propose a new robust water-marking scheme for medical images stored in a distributed database with a hyperbolic structure. Our approach is to first generate a watermark from the patient information and the statistical parameters of the image. The watermark is then inserted into the image and fragmented before being distributed(...)

Phytochemical screening, antioxidant and anti-diabetic activities of Leptadenia hastata
Yssouf Karanga, Wende-Konté Hazael Conania Nikiema, Têeda Hamidou GANAME, Ousmane Ilboudo, Issa Tapsoba
Leptadenia hastata (L. hastata) is traditionally used in Burkina Faso to treat some diseases. Leaves extracts was assessed for antioxidant activities and α-glucosidase inhibition.
TLC analysis of fractions revealed the presence of quercetin in the ethyl acetate fractions of L. hastata and rutin in the n-butanol fraction. The results of radica(...)

New Zero Watermarking Scheme Based on Hyper-catadioptric System Model and Hyperbolic Geometry
Boureima Koussoube, Moustapha Bikienga, Telesphore Tiendrebeogo, Armand Kodjo Atiampo, Boureima Zerbo
In this paper we propose a new digital watermarking scheme for securing DICOM images in a distributed database. This new technique introduces no distortion to the images and will serve as a means of authenticating them. The database has a hyperbolic structure and its model is based on the Poincaré disk model, in which a hyperbolic tree is buil(...)

New Medical Image Hybrid Watermarking
Boureima Koussoube, Moustapha Bikienga, Telesphore Tiendrebeogo
Digital watermarking is a mechanism for protecting digital documents as a complement to cryptography. Despite the many solutions proposed in the literature, to our knowledge there is no universal solution that can be applied everywhere. In this paper, we propose a new hybrid medical image watermarking approach that is based on two watermarks.(...)
