maritime transport has been playing a decisive role in global trade. Its contribution to the air pollution of the sea and coastal areas has been widely recognized. The air pollutant emission inventories of several harbors in China have already been established. However,the emission factors of local ships have not been addressed comprehensively, and thus are lacking from the emission inventories. In this study, on-board emission tests of eight diesel-powered offshore fishing ships were conducted near the coastal region of the northern Yellow Bo Sea fishing ground of Dalian, China. Results show that large amounts of fine particles（ 0.5 μm, 90%） were found in maneuvering mode, which were about five times higher than those during cruise mode. Emission rates as well as emission factors based on both distance and fuel were determined during the cruise and maneuvering modes（including departure and arrival）. Average emission rates and distance-based emission factors of CO, HC and Pm were much higher during the maneuvering mode as compared with the cruise mode. However, the average emission rate of Nitrous Oxide（NOx） was higher during the cruise mode as compared with the maneuvering modes. On the contrary, the average distance-based emission factors of NOxwere lower during the cruise mode relative to the maneuvering mode due to the low sailing speed of the latter.

Objective:To test the effect of voltage-gated sodium channels (VGSCs) blockers on the motility and viability of human spermin-vitro and to evaluate the tested compounds as potential contact ***: Sperm samples were obtained from healthy non-smoking volunteers of age 25-30 years who had not taken any drug 3 months before and during the course of the study. The effect of VGSCs blockers evaluated from two pharmacological classes including antiarrhythmic (amiodarone, procainamide and disopyramide) and antiepileptic (carbamazepine, oxcarbazepine, phenytoin, and lamotrigine) drugs. They were tested on thein-vitro motility and viability of human sperm using Computer Assisted Semen ***:All tested drugs except oxcarbazepine showed dose dependent inhibition of total motility with significant reduction (Pmaximum concentration of 200 μm when compared with the control. The concentrations of drugs that reduced total sperm motility to 50% of control (half maximal inhibitory concentration) were 2.76, 14.16 and 20.29 μm for phenytoin, lamotrigine and carbamazepine, respectively;and 2.53, 5.32 and 0.37 μm for amiodarone, procainamide and disopyramide, respectively. The anti-motility effects were reversible to various degrees. There was statistically insignificant difference in the inhibition of sperm viability among amiodarone, procainamide and disopyramide. Phenytoin demonstrated the most potent spermicidal ***:VGSCs blockers have significant adverse effects onin-vitro motility of human spermatozoa. Soin-vivo studies are required to determine their potential toxicological effects on human semen quality, which is an important factor regarding fertility. moreover, these drugs have the potential to be developed into contact spermicidal.

Using a bidentate ligand, a Schiff base 4-（{[（Z）-（2-hydroxyphenyl）methyldene]amino}methyl）cyclohexanecarboxylic acid, complex I（mL2, where m = Cd（Ⅱ）） was synthesized and characterized by IR spectroscopy and X-ray crystallography. It crystallizes in monoclinic system, space group C2/c, m_r = 685.04, 0.34 mm × 0.26 mm × 0.14 mm, a = 54.050（3）, b = 6.1220（3）, c = 9.5081（5） A, β = 90.229（2）°, Z = 4, C_（30） H_（40） CdN_2 O_9 and V = 3146.2（3） A^3. Complex I was screened for its bactericidal activity against four bacterial strains Chromohalobactersalexigens, Chromohalobacterisraelensis, Halomonashalofila and Halomonassalina and fungicidal activity against Aspergillusnigerand Aspergillusflavus. Antimicrobial activity results showed that the synthesized complex displayed good anti-fungal activity against two fungal strains. It was found to be inactive against four different bacterial strains analyzed and was negative for bactericidal effect.

High-resolution aeromagnetic data of parts of middle Benue Trough, Nigeria (sheets 212, 213, 233 and 234) was interpreted by applying source Parameter Imaging (SPI) and Spectral Depth analysis with the aim of mapping out the magnetic lineaments and analysing magnetic signals coming from different sources. The results from the derivatives maps show major and minor lineaments trends in the NE-SW and NW-SE directions respectively. Results from SPI show the maximum sedimentary thickness of about -4546.7 m (-4.5467 km) around the region of Awe, Aman, Langtang south, Gassol and the north-eastern part of Donga. minimum depth of -167.9 m (-0.1679 km) around the region of north of Shendam, north of Wase, north-eastern part of Aman, Bantaji, Donga, Ibi and Bali. The residual map was divided into twenty-five sections. Spectral Depth was run for each of these twenty-five sections, the result shows that the depth to the deep magnetic source ranges between -0.65 km and -3.35 km. The depth to the shallow magnetic sources ranges between -0.03 km and -0.44 km showing the presence of magnetic intrusive bodies within the sediments. Since the sedimentary thickness of 3.0 km and above is only sufficient for hydrocarbon maturation and accumulation, then the results from this present study show that the study area might be sufficient enough for hydrocarbon maturation and accumulation.
