Background: Non traumatic gonalgia is the second most common reason for rheumatology consultations and accounted for 15.6% of rheumatological disorders in Abidjan. Objective: The aim of this work was to study the epidemiological and diagnostic features of non-traumatic gonalgia (NTG) in a black adult population from sub-Saharan Africa. Patients and Methods: This was a five-year retrospective descriptive study (January 2014 to December 2018) of black sub-Saharan African adult patients with non traumatic gonalgia seen in the rheumatology department of the Bouake University Hospital in Côte d’Ivoire. Results: Of 2198 patients seen for rheumatological conditions, 140 had non traumatic gonalgia (6.4%). The mean age of patients was 56.13 ± 13.3 years (extremes 20 and 87 years), and the sex ratio was 0.43 (42 men and 98 women). Gonalgia without swelling was observed in 33.6% of cases. Symptoms were predominantly progressive (97.1%), chronic (82.1%) and bilateral (50%). The causes of TNM were gonarthrosis (85%), septic arthritis (7.1%), reactive arthritis (2.9%), gout (2.9%), rheumatoid arthritis (1.4%) and chondrocalcinosis (0.7%). Gonarthrosis (119/140) was bilateral in 65 patients, bi- or tri-compartmental in 83, radiographic stage (Kellgren and Lawrence) III in 80 and IV in 15. A germ was isolated in two cases of septic arthritis (methicillin-sensitive Staphylococcus aureus and Streptococcus pneumoniae). Conclusion: GNT is common in rheumatology practice in Bouake, and mainly affects women in their fifties. It is most often a chronic bilateral gonalgia, with gonarthrosis as the main etiology.

Objective: To study the epidemiological and diagnostic features of chronic rheumatic disease (CRD) in a black population in sub-Saharan Africa. Patients and Methods: Retrospective descriptive study over eight years (January 2005 to December 2012) of patients seen for CRD in rheumatology hospitalization at the CHU de Cocody in Abidjan, Côte d’Ivoire. Results: Of 3147 hospitalized patients, 92 had CRD, a frequency of 2.9%. The mean age of patients was 43.50 ± 15.6 years (extremes: 10 to 79 years). The sex ratio was 0.08 (7 men and 85 women). The socio-economic level was low in 44 patients (47.8%), medium in 44 patients (47.8%), and high in 4 patients (4.4%). The reasons for consultation were polyarthritis (64.1%), polyarthralgia (30.4%), and oligoarthritis (5.4%). The mean duration of symptomatology was 19 months (range: 3 to 20 years). The mean length of hospital stay was 14.2 ± 7.7 days (range: 2 to 36 days). The CRD observed were: rheumatoid arthritis (59.8%), systemic lupus erythematosus (23.9%), mixed connective tissue disease (6.5%), undifferentiated connective tissue disease (3.3%), polymyositis (3.3%), systemic scleroderma (2.2%), and systemic vasculitis (1%). Conclusion: CRD is not uncommon in rheumatology hospitals in Abidjan. Diagnostic delays are long, and rheumatoid arthritis and systemic lupus erythematosus are the most frequently encountered conditions.

A Generic and Reliable Land Acquisition Protocol Implementation for Sub-Saharan Africa Countries

引用

Journal of Computer and Communications 2024年第1期12卷 208-245页

作者： Bayomock Linwa André Claude traore Hamidou Department of Computer Science International University of Grand-Bassam Grand-Bassam Ivory Coast

Land acquisition is subject of many frauds worldwide. In Africa countries, land acquisition frauds are a real curse. Main reasons of the high land acquisition frauds in Africa are a lack of a reliable land acquisition protocol implementation, no centralized information system that records land transactions and integrates all actors, lack of education about the acquisition protocol and lack of applied sanctions in case of frauds. As of sanctions, the issue is bound to the corruption plague in Africa. Authorities that are supposed to rule the laws are not well paid and are part of the corruption scheme. Most frequent frauds are multiple sales of the same land, falsified land title, false owner identification. In Africa, a land belongs generally to the first residents of the area. To claim ownership of a land, an owner should be recognized by the rural or city authorities. To achieve this recognition, he must obtain from those authorities an attribution letter. The author proposed a complete and reliable land acquisition protocol named ACLAP (Africa Countries Land Acquisition Protocol). The purpose of this paper is to explain the main components of the protocol implementation and show its efficiency when confronting fraud threats. In this paper, a Generic and Reliable Land Acquisition Protocol Implementation in Sub-Saharan Africa countries context is proposed. The platform keeps relevant land transaction information for administrators, managers, buyers, sellers, or for people consultation purpose. The application may be used in village, city, department, region, or country for land management decision making.

Wiener amalgam spaces are a class of function spaces where the function’s local and global behavior can be easily distinguished. These spaces are ex-tensively used in Harmonic analysis that originated in the work of Wiener. In this paper: we first introduce a two-variable exponent amalgam space (Lq(),lp())(Ω). Secondly, we investigate some basic properties of these spaces, and finally, we study their dual.

Introduction: Pesticides are currently an essential component of agricultural production techniques for controlling pests and weeds. In Burkina Faso, non-compliance with good practice in the use of pesticides poses a real health problem for the population. This study examines the health risks associated with pesticide management in rice-growing areas. Material and Methods: A field survey was conducted in Bama, involving farmers, focusing on their socio-demographic characteristics, pesticide usage, and health effects. Cholinesterase levels were measured in subsample of farmers using a portable device. Data were analysed using Microsoft Excel, calculating means and percentages for various practices. Health consultations, protection methods, and pesticide management were studied. Erythrocyte acetylcholinesterase activity was compared before and after treatment. Data were categorised into classes based on inhibition levels, and correlation analyses determined relationships between variables such as age, years of experience, and cholinesterase activity. Results: The results indicate that rice cultivation is mainly carried out by a fairly young population, with nearly 63% being under the age of 50. Common poor practices in pesticide use include improper storage and reuse of leftover pesticides. Seven types of pesticides were identified, including organophosphates such as glyphosate, which was used in 26.7% of cases. This organophosphate has resulted in class B poisoning, causing a 30% - 50% reduction in erythrocyte cholinesterase activity. The health effects of pesticide use are felt by agricultural farmers through various symptoms of poisoning. Conclusion: To reduce the occurrence of pesticide poisoning, it is essential to launch information and awareness campaigns among the population and farmers to promote safe practices in pesticide use in Bama, Burkina Faso.

Understanding metal accumulation at organ level in roots, leaves and seeds in O. glaberrima (OG) is crucial for improving physiological and metabolic aspects in growing Asian and African rice in salted areas. The micro-analytical imaging techniques are required to reveal its accumulation and distribution within plant tissues. PIXE studies have been performed to determine different elements in rice plants. The existing microbeam analytical technique at the iThemba LABS will be applied for the 2D image mapping of fresh rice tissues to perform a concentration of low atomic mass elements (such as Al, Si, P, S, Cl, Ca, Ti, Mn, Fe, Cu, Br, Zn and K) with detection limits of typically 1-10 μg/g. Comparison of the distribution of the elements between leaves, root and seed samples using uptake and distribution of elements in particular environmental conditions with potential amount of salt in water have been performed. We are also expecting to indicate metal exclusion as salt tolerance strategies from leaves, root, and seed compartments using matrix correlation between samples and between elements on rice species.

American Journal of Plant Sciences 2024年第5期15卷 387-402页

作者： Bandiougou Diawara Sory Diallo Brahima traore Scott Staggenbord Vara Prasad Institut D’ Economie Rurale (IER) Bamako Mali Manhattan KS USA

In Kansas, productivity of grain sorghum [Sorghum bicolor (L.) Moench] is affected by weather conditions at planting and during pollination. Planting date management and selection of hybrid maturity group can help to avoid severe environmental stresses during these sensitive stages. The hypothesis of the study was that late May planting improves grain sorghum yield and yield components compared with late June planting. The objectives of this research were to investigate the influence of planting dates yield and yield components of different grain sorghum hybrids, and to determine the optimal planting date and hybrid combination for maximum biomass and grains production. Three sorghum hybrids (early, medium, and late maturing) were planted in late May and late June without irrigation in Kansas at Manhattan/Ashland Bottom Research Station, and Hutchinson in 2010;and at Manhattan/North Farm and Hutchinson in 2011. Data on dry matter production, yield and yield components were collected. Grain yield and yield components were influenced by planting date depending on environmental conditions. At Manhattan (2010), greater grain yield, number of heads per plant, were obtained with late-June planting compared with late May planting, while at Hutchinson (2010) greater yield was obtained with late May planting for all hybrids. The yield component most affected at Hutchinson was the number of kernels∙panicle−1 and plant density. Late-May planting was favorable for late maturing hybrid (P84G62) in all locations. However, the yield of early maturing hybrid (DKS 28-05) and medium maturing hybrid (DKS 37-07) was less affected by delayed planting. The effects of planting dates on yield and yield components of grain sorghum hybrids were found to be variable among hybrid maturity groups and locations.

Despite its low resistance to humidity, adobe remains the most widely used material for housing construction, particularly in developing countries. The present study aims to assess different modes of use of fermented RH and to evaluate their influence on the behavior of raw earth for application in plaster. The influences of two types of RH are evaluated: granular rice husk (RHg) and powdered RH (RHp). The clay mainly consists of clay (40%), silt (22%), and sand (38.4%), with a small proportion of gravel (0.24%). Its liquidity limit is 40% and the plasticity index is 26.5%. The mixtures were designed using earth and each of the two rice husks at the volumetric content of 10%, 15% and 20% of the total volume mixed with water 36.5%, 38.5% and 40.3% and fermented for three weeks. Each fermented mixture was added to the soil to form the paste, and 40 × 40 × 160 mm3 test speciments were made for characterization. The results generally show an improvement in the physico-mechanical properties and water resistance of the mortars containing fermented RH, with an optimal content between 10% and 15%. The powdered RH improved the performance of the mortar better than granular RH.
