This study attempted to optimize the adaptive neuro-fuzzy inference system (ANFIS) using particle swarm optimization (PSO) and a genetic algorithm (GA) for calculating occupational risk. Numerous studies have shown that the ANFIS is a good approach for predicting engineering problems. However, it is not well investigated in the area of risk assessment.

Lead poisoning, is currently recognized as a real public health problem, The WHO classifies lead as one of 10 chemicals of serious public health concern. In Algeria and North Africa, to date, no study on the evaluation of lead impregnation has been carried out at the national level. The main objective of this work is to assess the exposure of the general Algerian population to lead.

The synthesis, acid-base equilibrium, aggregation properties, and antibacterial activity were investigated. Conductivity and fluorescence were used to establish critical micelle concentrations.

Extensive phylogenetic investigations based on 18S-rRNA gene sequences have shown that (Apicomplexa: Haemogregarinidae) is able to infest a large diversity of freshwater turtle species, including the European pond turtle , the Sicilian pond turtle , the Caspian turtle , the Mediterranean pond turtle , and the Western Caspian turtle , among others. From the same molecular markers, is further considered to be a complex of cryptic species predisposed to infect the same host species.

Aim: To assess the acceptance of COVID-19 vaccines among health workers in Sidi Bel Abbès and to identify the psychological determinants of vaccination acceptance.
Methods: A descriptive cross-sectional study was conducted from December 01, 2021 to January 31, 2022 and involved health professionals in Sidi Bel Abbès, through an anonymous questionnaire.
Introduction: Clove essential oil is isolated from the dried flower buds of Syzygium aromaticum from which many biological activities have been reported. The aim of this work was to develop a cream for topical use containing clove essential oil (HE) as an active ingredient and to test its biological activity.
Material And Methods: Clove EO was extracted by hydrodistillation, its chemical composition was analysed by Gas chromatography-mass spectrometry (CG-SM).
Several endemic species of Blaps occur in Tunisia, and the species Blaps nefrauensis nefrauensis has been reported in Moulares (urban zone in west-central Tunisia), where it lives and reproduces in home gardens and old buildings. The aim of this work is to study the life cycle of the darkling beetle, considering both field and laboratory rearing conditions. As a result, the beetle species has different developmental stages (egg, larva, prepupa, pupa, and adult) that last about 15 months.

The opportunistic microorganisms provoke environmental contaminations in health and storage facilities to represent a serious concern to health security. The present work investigates the antifungal activity of two amino-alcohols based cationic surfactants such as CEtOH, CPrOH (with = 14 and 16 are the carbon numbers of alkyl chain and EtOH = Ethanol and PrOH = Propanol) against a collection of different species (, , respectively.
View Article and Find Full Text PDFSpecies of Haemogregarina are apicomplexan blood parasites that use vertebrates as intermediate hosts. Due to limited interspecific morphological characters within the genus during the last decade, 18S rRNA gene sequences were widely used for species identification. As coinfection patterns were recently reported from nuclear molecular data for two sympatric freshwater turtles Mauremys leprosa and Emys orbicularis from Tunisia, our objectives were to design COI specific primers to confirm the presence of three distinct species in both host species.

Methods: An expert consultation was conducted during the first week of May 2020, using the "Delphi" technique. An email was sent to them requesting the formulation of a lesson, in the form of a "Public Health" good practice recommendation.
Objective: Identify the lessons learned in the Greater Maghreb, during the first semester of the fight against the COVID-19 pandemic, in the field of response.
Methods: During the first week of May 2020, a consultation of experts was conducted, using the "Delphi" technique, through an email asking each of them, the drafting of a good practice recommendation for "Public health". The Group coordinator finalized the text of the lessons, later validated by the signatories of the manuscript.
Objective: To compile the lessons learned in the Greater Maghreb, during the first six months of the fight against the COVID-19 pandemic, in the field of "capacity building" of community resilience.
Methods: An expert consultation was conducted during the first week of May 2020, using the "Delphi" technique. An email was sent requesting the formulation of a lesson, in the form of a "Public Health" good practice recommendation.
Introduction: Medication adherence is the cornerstone of the successful drug management of a chronic disease.
Aim: To develop a systematic review and meta-analysis of the prevalence and the factors associated with non-adherence in patients with type 2 diabetes in North African countries.
Methods: A literature search was conducted on Medline via Pubmed with a complementary search on Google Scholar.
While Liocranidae is a family encompassing 283 species distributed in 32 genera (World Spider Catalog 2019), the genus Agraecina Simon, 1932 currently counts only six described species: Agraecina canariensis Wunderlich, 1992 from the Canaries, A. cristriani (Georgescu, 1989) from Romania, A. hodna Bosmans, 1999 from Algeria, A.
View Article and Find Full Text PDFHaemogregarina species are apicomplexan blood parasites infecting vertebrates such as fish, lizards, and turtles. Due to the high morphological similarity of the erythrocytic stages infecting host species, it has always been a challenge to identify the true diversity of these parasites. Therefore, taxonomic studies are presently based on the combination of morphological and molecular data.

Methods: This scoping study was based on a "Google Form" covering three constituents of the response plan against COVID-19: responders, activities and crisis communication. The attitudes of health professionals who are working in Tunisia and Algeria were measured through the Likert scale with four propositions, grouped in pairs, during the analysis.
Context: The Maghreb Central, like all the countries of the world, was strongly mobilized (governments, ministries of health, population, civil society) in the response against COVID-19, immediately after the registration of the first cases on its territory (end of February, beginning of March) and according to pre-established control strategies.
Objectives: Describe the perceptions of health professionals in the Central Maghreb (Tunisia, Algeria and Morocco) as to the Strengths/Opportunities and Weaknesses/Threats of the national response plans against COVID-19, during the first weeks of their execution, and report their proposals for optimizing the performance of control strategies.
Methods: This is a qualitative study of the perceptions of health professionals in the Maghreb Central regarding their experience of the first six weeks of fighting the COVID-19 pandemic.
Neurogenic paraosteoarthropathies are ectopic ossifications which develop near the joints. They are a process of neo-ectopic osteogenesis occurring after central or peripheral neurological lesions, in some types of comas (oxygen carbon intoxication, prolonged sedation) and following peripheral traumas including burns. They inolve almost exclusively the large proximal joints of the limbs.

The cosmopolitan species, Porcellionides pruinosus (Brandt, 1833), exhibited a geographical variation of its morphological features and its reproduction pattern. In fact, some Tunisian populations had a seasonal reproductive period and other ones showed a reproductive activity. A phenetic analysis has been performed to compare populations belonging to P.
