Assessment of impact of ten days fishing ban in the major spawning grounds of hilsa (Tenualosa ilisha, Fisher and Bianchi, 1984)

A study was undertaken to find out the impact of ten days fishing ban in the major spawning grounds of hilsa during October to December. The study revealed a positive impact of fishing ban during spawning season on reproduction success of hilsa. Proportionate distribution of male and female hilsa also showed a significant level of distribution in and around the spawning grounds where the ratio was 35:65. Percent of oozing hilsa during fishing ban period in the spawning grounds was observed 1.61%. About 5% spent hilsa was observed in the fish landing centers and was compared with the data of Global Environment Facility (GEF) and Bangladesh Fisheries Research Institute (BFRI) studies and was found about 2.80-3.57 times higher than that of the findings of 2002 and 2003. Estimated egg production value showed about 46,800 Kg of eggs could have been produced that indicating a positive impact of 10 days fishing ban in spawning season. Abundance of higher percentages of gravid hilsa was found which were not available in the same quantity and condition in the non-fishing ban period. During the present investigation, fairly higher amount of spent hilsa and juveniles were also observed in the spawning grounds. Along with the jatka fry, spawn and fries of other fishes were also found in higher quantity than the previous years and thus it is assumed that fishing ban also might have positive impact on the successful breeding of other fishes. Overall, the fishing ban was found effective for successful breeding of hilsa.

两种聚砜预聚物和多嵌段聚合物的合成及形态结构

以双酚A、酚酞和4，4'-二氯二茉砜为单体，合成了双酚A型聚砜和酚酞型聚砜两系列不同分子量的预聚物。将这两系列预聚物作为硬段，以不同分子量的聚氧化丙烯或聚氧化丙烯-聚二甲基硅氧烷作为软段，以二异氰酸酯二苯甲烷作为硬段和软段间的连接桥，合成了硬、软段分子量不同的双酚A型聚砜-聚氧化丙烯多嵌段聚合物、双酚A型聚砜-（聚氧化丙烯-聚二甲基硅氧烷）多嵌段聚合物的酚酞型聚砜-聚氧化丙烯多嵌段聚合物。经红外光谱分析、分子量测定和粘度测定等表征，确认产物与预想结果相符。用示差扫描量热仪、扭辨分析仪和电子显微镜研究了硬段预聚物和多嵌段聚合物的形态结构及性能。硬段预聚物在实验温度范围（-30到250 ℃）内，具有三种转变，分别为局部短程有序（60到70 ℃）的破坏，玻璃化转变，玻璃化温度与分子量的关系如下式所示：双酚A型聚砜 T_g = 462 - 8.07 * 10~4/M-bar 酚酞型聚砜 Tg = 519 - 8.33 * 10~4/M-bar和较大范围的长程有序性的解离。在双酚A型聚砜-聚氧化丙烯多嵌段聚合物体系中，当硬段分子量固定在1500时，多嵌段聚合物的形态结构随软段的分子量降低由两相结构（软段分子量≥1000）变成为单相结构（软段分子量为450）。当软段分子量固定为2000时，多嵌段聚合物的形态结构随硬段的分子量增加由单相结构（硬段分子量为700）变为两相结构（硬段分子量≥1500）。双酚A型聚砜-（聚氧化丙烯-聚二甲基硅氧烷）多嵌段聚合物均显示两相结构（软段分子量2400，硬段分子量≥700）。在硬段分子量增加到3900就发生相倒转，软段变为分散相，硬段成为连续相。酚酞型聚砜-聚氧化丙烯多嵌段聚合物，当固定分子量为2000时，硬段分子量在本工作的变化范围内，850至1900，所得产物均为两相结构。

Archaeological Excavations at 18AP14: The Victualling Warehouse Site, 77 Main Street, Annapolis, Maryland, 1982 - 1984

The Victualling Warehouse Site, located at 77 Main Street in Annapolis, Maryland, was excavated by Archaeology in Annapolis during the summers of 1982 and 1983 and the fall of 1984. Funding was provided by Historic Annapolis, Incorporated (now Historic Annapolis Foundation), the University of Maryland, the Maryland Committee for the Humanities, and the Maryland Commission on the Capital City. This site has been used for commercial and residential purposes since the 1740's. During the Revolution the warehouses were used as a victualling office to supply American troops. A fire in 1970 destroyed these buildings and the present structure, also used as a store, was built about twenty years later. Over the three years of excavation, a total of 36 5 foot by 5 foot units were excavated revealing several features, including the foundations of one of the eighteenth century warehouses.
