Effects of the Insecticide Sevin on Survival and Growth of the Cockle Clam <i>Clinocardium nuttalli</i>
No full text Experiments are reported on the effects of the insecticide Sevin and its hydrolytic product, 1-naphthol, on the survival, growth, and food consumption of larval and juvenile cockle clams (Clinocardium nuttalli). Clams were tested in standing sea water at a salinity of 25‰ and a temperature of 19 ± 2.0 C, and were fed cultures of the unicellular alga Monochryis lutheri. Algal cell concentrations ranged from 10,000 to 200,000 cells per ml of test solution. Toxicant concentrations ranged from 0.1 to 10.0 mg/liter.Larvae exposed to Sevin concentrations of 0.8 mg/liter were dead by day 7 of the test, and the growth of those exposed to 0.4 mg/liter was reduced by 15%. Sevin was less toxic than 1-naphthol to juvenile clams, the respective 96-hr TLm's (median tolerance limits) being 3.75 and 2.70 mg/liter. The growth of juvenile clams was reduced more by 1-naphthol than by Sevin. The food consumption of juvenile clams exposed to 1.6 mg/liter of Sevin was markedly reduced and their food conversion efficiency was impaired.Adult clams exposed to Sevin concentrated the toxicant in their tissues; maximum concentrations were reached after 12 hr of exposure. Clams exposed at 11 C concentrated more toxicant than those exposed at 20 C. Tissue concentrations of toxicant decreased sharply after the clams had been in clean sea water for 12 hr. </jats:p
Effects of the Insecticide Sevin on Various Stages of the Dungeness Crab, <i>Cancer magister</i>
No full text Of the life-history stages of the Dungeness crab, Cancer magister, the early larvae are more sensitive to Sevin than are juveniles and adults. A concentration of 1.0 mg/liter did not affect egg hatching but prevented molting of all prezoeae to zoeae. The concentration that killed 50% of the first stage zoeae during a 96-hr exposure (96-hr EC50 for death) was estimated to be 0.01 mg/liter. Few zoeae were killed in 24 hr by 82.0 mg/liter, but the 24-hr EC50 for death within 15 days after the exposure was estimated to be 0.015 mg/liter. The 24-hr EC50 for cessation of swimming, which was not always permanent, was 0.0065 mg/liter. Survival of zoeae after 25 days exposure to concentrations of 0.0001, 0.00032, 0.001, 0.0032, and 0.01 mg/liter were 83, 60, 69, 21, and 0%, respectively, and control survival was 79%. Molting was delayed at a concentration as low as 0.0001 mg/liter.Young juvenile crabs are more sensitive to Sevin than are older juveniles or adults. The 24-hr EC50's for death or irreversible paralysis were estimated to be 0.076 and 0.35 to 0.62 mg/liter for second and ninth stage juveniles, respectively. The behavior, growth, and survival of juvenile crabs were not affected when the animals were exposed to 0.032 mg/liter of Sevin for 24 hr and then held in clean sea water for 44 days. The 24-hr and 96-hr EC50's for death or irreversible paralysis were 0.49 and 0.26 mg/liter, respectively, for adult crabs. After eating cockle clams that had just been exposed for 24 hr to 1.0, 3.2, and 10.0 mg/liter of Sevin, 22, 77, and 100% of adult crabs, respectively, were irreversibly paralyzed within 6 hr. The significance of these findings in field application of Sevin to control oyster pests and predators is discussed. </jats:p
Des projets inédits concernant les pompes funèbres du Grand Condé par Pierre Paul Sevin (1687)
No full textUnpublished drawings about the funerals of the Grand Condé by Pierre Paul Sevin (1687).
Conde died on December 11 1686. For this nationwide event, two designers, Jean I Berain and Pierre Paul Sevin, conceived drawings of projects for funeral ornaments at Notre-Dame of Paris and the Jesuit church Saint-Louis, under the leading of Father Ménestrier. Berain’s drawings were prefered to Sevin’s because of their classical inspiration, while Sevin, who had already worked with Menestrier long before 1686, faithfully rendered the latter’s notion of a decoration loaded with symbols and writing. However, Paul Sevin's designs, known from unpublished drawings, don’t mean any excessive dependance on Menestrier. The artist expresses his skill through very personal means, placing a staircase, for instance, in each mausoleum, a novelty at the time which completly changed the relationship between the corpse of the deceased and the congregation, thus serving the funeral service better.Chantrenne Damien.

Design and implementation of a man-overboard emergency discovery system based on wireless sensor networks
No full textRecently, wireless sensor networks (WSNs) have been widely employed in many different fields such as military, surveillance, health, agricultural, automation, and environmental monitoring. This paper presents a designed and implemented WSN-based man-overboard emergency discovery system, abbreviated as W-MEDS, that discovers the location of a person in emergency circumstances and runs an alarm system on a ship. The developed W-MEDS carries out a fast man-overboard (MOB) discovery and initiates the vital rescue procedure. It mainly consists of a WSN and a control and discovery system. When a MOB accident occurs, this situation is easily detected through the WSN nodes capable of real-time sensing (i.e. temperature, humidity, and acceleration) and the system enables location estimation. The control and discovery system analyzes and displays the received data from the WSN nodes. The most noteworthy advantage of the proposed W-MEDS is that it enables both real-time alarm monitoring and fast recovery. In addition to the implementation of the W-MEDS, considering hardness in performance evaluation of the real system, it has also been simulated in the OPNET Modeler to confirm the accuracy for different sizes and numbers of nodes
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Design and implementation of a new quality of service-aware cross-layer medium access protocol for wireless body area networks
No full textWireless body area networks (WBANs) consist of tiny sensors that enable monitoring the health status of a person. quality of service (QoS) is a major challenge for WBANs due to the importance of vital sign information. Therefore, many QoS-based medium access control (MAC) protocols and technologies have been developed to overcome this problem. Standardization of various technologies and protocols must be addressed. ISO/IEEE 11073 personal health data standards aim to provide interoperability between healthcare devices and technologies. This paper presents a new QoS-aware cross-layer MAC protocol based on the ISO/IEEE 11073 standards that employs a slot allocation scheme, multi-channel architecture, priority mechanism, admission control, and cross-layer solution. The proposed MAC protocol has been modeled and simulated by OPNET Modeler. In addition, the proposed MAC protocol is compared with standard technologies and recent protocols in the literature, and it achieves better results for end-to-end delay, packet loss ratio, and throughput parameters.
