First Insight Into Nutrition Effect on Spawning and Larvae Rearing of the Clam Ruditapes Decussatus L
First insight into nutrition effect on spawning and larvae rearing of the clam Ruditapes decussatus L. from Dakhla Bay 1Yassine Ouagajjou, 2Touryia El Aloua, 3Mohamed El Moussaoui, 1El Mustafa Ait Chattou, 4Adil Aghzar, 3Younes Saoud 1 National Institute of Fisheries Research, INRH, Casablanca, Morocco; 2 Faculty of Science, Chouaib Doukkali University, El Jadida 24000, Morocco; 3 Faculty of Science, Abdelmalek Essaadi University, Tétouan 93002, Morocco; 4 Higher School of Technology, Sultan Moulay Slimane University, Khénifra, Morocco. Corresponding author: Y. Ouagajjou, [email protected]; [email protected] Abstract. The local clam Ruditapes decussatus has been a widespread bivalve along the natural beds in Dakhla Bay (Morocco). But, nowadays its overexploitation during many years has prompted the depletion of its occurrence in many extents and also has limited the availability of natural spat. In this study, the influence of nutrition on spawning, fertilization and larvae rearing was assessed for the first time. The potential of oocytes accumulation and release was highly influenced by the quality of microalgae combination (F = 20.7, p < 0.001) rather than their availability (F = 4.092, p < 0.05). Nevertheless, the eggs fertilization was also significantly affected by diet and ration respectively (F = 7.347, p < 0.01 and F = 4.645, p < 0.05). For larvae rearing, as regards to physiological responses, small size strains Isochrysis galbana and Pavlova lutheri are the most suitable regimen during early larvae phase, while diatom Chaetoceros calcitrans and large size strain Tetraselmis chui are more appropriate during late larvae phase. Therefore, the mixture of the four microalgae was the only diet that led to metamorphosis and settlement throughout this experiment. -

Harmful Environmental Exposures and Vulnerable Populations Environmental Health in Nursing
Unit II: Harmful Environmental Exposures and Vulnerable Populations Environmental Health in Nursing Unit 1I: Harmful Environmental Exposures and Vulnerable Populations INTRODUCTION Unit 1 highlighted various roles of the nursing profession where knowledge of environmental exposures is central to practice. In Unit 2, the focus is upon population groups who are most vulnerable to harmful environmental exposures. While risks to adverse health outcomes can vary according to geography, housing and location of environmental exposures, some humans are at greater risk due to their biophysical and sociopolitical vulnerability. Unit 2 explains risk and vulnerability across the lifespan with a focus upon specific vulnerabilities and harmful effects at various developmental stages. A second chapter highlights anticipatory guidance for parents and caregivers to reduce environmental exposures for children from infancy to adolescence. Third, Unit 2 considers the impact of social determinants of health, which are commonly referred to as factors where people live, learn, work, play and pray. Social determinants at neighborhood and community levels impact individual level exposures. Finally, Unit 2 includes a chapter about the effects of social determinants on the vulnerability of immigrants and refugees. See Unit 5: Sustainable Communities, for the chapter about Environmental Justice, which addresses the adverse outcomes for those who live in more environmentally hazardous areas.

“Hard, Bitter, Unpleasantly Necessary Duty” a Little-Known World War II Story of the Philippines
A Filipino medical assistant bandages the injured arm of a woman in a PCAU clinic at San Rogue on Leyte Island, January 1945. “Hard, Bitter, Unpleasantly Necessary Duty” A Little-Known World War II Story of the Philippines By David Smollar 6 Prologue Summer 2015 n the steamy dawn of Friday, May 4, 1945, hundreds of Filipino residents in the western Leyte port of Palompon lined the shore along the Visayan Sea. The special U.S. Army team known as PCAU 17, after four months of helping to heal and jump-start their war-torn com- munity, was sailing to another island needing aid. For more than two hours under an already baking sun, they watched the boat slowly make its way from Ithe pier, serenading the departing soldiers and wishing them Godspeed. “The local citizens sought us out to wring our hands, thank us, and bless us, and thank us again in their own version of Bon Voyage,” the medical officer with Philippine Civil Affairs Unit (PCAU) 17 wrote in one of his many letters home. “Lots of emotion was expressed,” he added. “A real poverty stricken mother of a skeletal child I saw during the first days after fighting stopped, reckoned now as long ago in ‘war time,’ handed me a dozen fresh eggs. Another former patient gave me fried chicken. The hospital men and women, they financed a pair of house slippers and tea cloth as a ‘thank you’ for me. “You know, I’m pretty gruff, and I was often damn tough in getting these people to understand how to fight illness and disease, but all this made me, well, downright sentimental. -
