Levrier Bay, located in the western part of Mauritanian Cost, has a strategic position in Mauritania’s fish economy and reproduction environment. Recently, fishmeal factories have multiplied in the bay. This study was carried out in Levrier Bay. It is the first one in this area which is interested in assessing the environmental impact of fishmeal factory discharges by measuring several parameters such as suspended matter, chemical oxygen demand (COD), biological oxygen demand (BOD), conductivity, turbidity, and salinity. A total of 27 samples were collected at 9 sites distributed on the link between effluents from factories and the Atlantic Ocean (discharge site). Results show that some parameters are over permissible values, like suspended matter content (SS), which reached 2020 mg. L.-1 level. The turbidity measure shows excessively high values (50 to 961 mg.L.-1); impacted by effluents at the reject point, the seawater conductivity and salinity are particularly low (4.53 to 188.2 and 13 to 56.4, respectively). The total organic carbon (TOC) values ranged from 200 to 780 mg/L, whereas the highest measured level of chemical oxygen demand was 4010 mg.L.-1 Biochemical oxygen demand content ranged from 685 to 961 mg/L. The biodegradability index (COD/BOD) shows that these effluents are not easily biodegradable because the index > 3.

Eco-design is a key trend in industry today. DCNS, a major French shipbuilder, has taken a position in this market thanks to a consortium of several concerned specialists: Arts et Métiers ParisTech, Ifremer, SITA Suez, and Bureau Veritas. The purpose is to create a tool to assess the impacts on the aquatic environment, but also an eco-design tool making it possible to improve design. Based on life cycle analysis (LCA) principles, it is improved by a specific eco-indicator for the maritime environment and the possibility of a return to design at the design stage. This tool is currently being developed by a computer engineer. The functionalities proposed and expected in the tool requirements are being tested by this development.

Background Integrated diagnostics is increasingly gaining scientific traction as it promises to address several challenges currently facing diagnostic medicine. These challenges range from the need for improved diagnostic accuracy to optimized timing of diagnostic procedures, to the variety of diagnostic markers and thus the complexity of their interpretation, and finally to economic pressure. Methodical innovations While many of these challenges may be difficult to solve with a monomodal approach, the integration of laboratory markers and imaging procedures promises to allow both disciplines to achieve their actual clinical potential. Combining complementary diagnostic approaches can help to improve the interpretation of measurements, provide a better cost-effectiveness particularly when cutting-edge techniques are used for specific indications, and facilitate optimized timing and rational choice of appropriate diagnostic approaches for disease surveillance. Furthermore, close interdisciplinary assessment of diagnostic results will increase diagnostic accuracy and will enable selection of specific patient cohorts at increased risk for certain diseases who are suitable for further testing. Conclusion The potential of an integrated diagnostic approach represents a strategic goal for diagnostic disciplines as it achieves better visibility and greater clinical impact. In addition to close collaboration among relevant diagnostic experts, an appropriate structure for integrated data evaluation needs to be established to provide actionable health guidance so that integrated diagnostics can be implemented in standard care.

Professionals from minority world nations are increasingly consulting with majority world nations to develop intervention and educational training programs, yet minority world programs cannot be simply transferred to majority world countries. Participatory action research (PAR) provides a methodology that can be used to facilitate the development of programs that are useful for and sustainable by the majority world communities. This article describes the principles of PAR and gives examples of the ways that cultural values and behaviors may influence interactions between minority and majority world persons. An understanding of these cultural variations in values is essential for the successful implementation of PAR and will reduce miscommunication and incorrect interpretations of behaviors.

Purpose: Vietnamese children’s performance on language-based processing tasks of fast-mapping (FM) word-learning and dynamic assessment (DA) word- and rule-learning tasks were investigated. Method: Twenty-one first- and second-generation Vietnamese preschool children participated in this study. All children were enrolled in 2 Head Start programs in a large city in the Midwest. All children had passed a developmental assessment and routine speech, language, and hearing screenings. All participants were taught 4 invented monosyllabic words in an FM word task, an invented monosyllabic suffix rule (- po ) meaning \"a part of\" in a DA rule task, and 4 invented bisyllabic words in a DA word task. Potential relationships among task performances were investigated. Receptive task performances, expressive task performances, and task totals were added to create receptive total, expressive total, and accumulated performance total (APT) scores. Relationships among receptive total, expressive total, and APT scores were also investigated. Results: Significant correlations were found between FM word, DA rule, and the receptive total. The expressive total correlated with all task total scores, APT, age, and modifiability scores. Modifiability scores correlated with the two DA tasks, expressive total, and the APT. Findings indicate that FM word and the expressive total were positively correlated with most of the other tasks, composite totals, and age. Clinical Implications: Performance on language-based processing tasks may provide valuable information for separating typically developing Vietnamese preschool children from their peers with language disorders. Practitioners should consider linguistic characteristics of target stimuli. Comparisons should include task, receptive, expressive, and APT.

The number of individuals in the United States whose native language is Vietnamese has increased dramatically during the past decade. To work effectively with Vietnamese speakers, speech-language practitioners need to understand basic aspects of the Vietnamese language, especially the sound system, and how it differs from English. The purpose of this report is to provide basic information that can be used by practitioners to understand not only the differences between Vietnamese and English phonology, but also the influence of dialects. Characteristics of Vietnamese phonology and speech samples of three native speakers, representing the northern, central, and southern dialects, are used to illustrate information from the literature in this tutorial. Clinical Implications include considerations for assessment and intervention with Vietnamese individuals who may have a phonological disorder.

Purpose: Interviews with Southeast Asian families and Head Start staff, participant observation of family and staff conferences, observations of teacher-child and parent-child interactions, and a review of all written Head Start information given to parents were used to gain information regarding how Southeast Asian parents, children, and Head Start staff make sense of early childhood education, their roles in child learning, and the identification of disabilities or learning problems. Methods: Nine Southeast Asian families and 10 children were participants. One Vietnamese and 3 EuroAmerican Head Start staff members participated in a series of two or three semistructured individual interviews. Additionally, 3 families were observed during scheduled conferences with Head Start staff. Each child was observed at Head Start during meals, center time, and outdoor play time. All literature routinely given to parents was analyzed. Ethnomethodology (the study of how participants make sense of their world) was used in collection and analysis of the data. The constructs of organizational culture (Schein, 1987, 1992), independence/interdependence, and power/distance relationships were used to help to make sense of the data themes. Clinical Implications: Both families and staff were unaware of differences in their beliefs and values in the areas of education, parenting, child learning, and disability, which led to confusion and misunderstanding. All early childhood staff need to be aware of their underlying assumptions and how these may affect their interactions with children and families who may have different assumptions and expectations.

SummaryThe dynamic mechanical behaviour of random copolymers of LC monomer - 1-(hexyl-oxycarbonyl)ethyl 4-[4-(methacryloyloxy)benzoyloxy]benzoate (HB) and octyl methacrylate (OMA) was studied in the main transition and flow regions. Even though the aliphatic end groups of the side chain of HB and OMA are roughly the same, the Tg temperature of poly(HB) is ∼ 80 K higher than that of poly(OMA); this fact is due to the presence of the stiff phenyl benzoate mesogenic group in the side chain of HB. With increasing content of OMA in the copolymer the superimposed curves of the storage G′p and los G″p moduli at a constant temperature shift towards shorter frequencies. It has been shown that this shift is mainly due to an increase of the free volume in the copolymers with increasing content of OMA. While HB monomer shows liquid crystalline (LC) properties, its polymer (poly(HB)) and random copolymers with OMA show only isotropic thermal behaviour because no flexible spacer is present in the side chain of HB which would decouple the main chain and mesogenic group motions. This means that neither the homopolymer of HB, nor its copolymers with a flexible comonomer retain the LC properties of the starting LC monomer, HB.

In a phase 3 trial, participants with early Alzheimer’s disease who received the monoclonal antibody lecanemab had less decline on measures of cognition and function at 18 months than those who received placebo.
